Description

FEED AND WATER MIXING DISPENSING HOPPER FOR LIGUID PHASE FEEDING

The present invention relates to a hopper, and more specifically, to a liquid feed and drinking water mixing and discharging hopper capable of automatically and uniformly mixing and supplying dry feed and drinking water.

In general, pig farms that raise pigs install automatic feeders that automatically supply feed inside pig pens. The configuration of such automatic feeders for pig farming is known from Korean Patent No. 10-1201545, Patent No. 10-1277590, etc. Specifically, the automatic feeder for pig farming includes an upper supply pipe arranged horizontally at the top through which feed is transported, a feed storage box that receives feed from the upper supply pipe and temporarily stores it, and a feed supply unit that supplies feed stored in the feed storage box to a feed plate arranged below. Here, the feed supply unit uses a screw or a rotary part, etc. connected to a shaft that is rotated by a motor, and a predetermined amount of feed is supplied to the lower feed plate according to the rotation of the screw or rotary part.

These conventional automatic feeders are mainly for supplying dry feed (dry feed) such as compound feed. Compound feed is feed made by appropriately processing and mixing two or more types of feed ingredients and various types of images according to the purpose of raising, and is mainly composed of powder or granule form. However, since the production cost per 1 kg of such compound feed is significantly high, the selling price is very high, which is increasing the difficulties of pig farms.

An alternative to these compound feeds is liquid feeding, which is a method of automatically and repeatedly feeding feed optimized for the growth of pigs by liquefying water, feed or liquid by-products, grains, and liquid raw materials in a large stirring tank for a set period of time. When weaned piglets are fed liquid feed, the surface cross-sectional area of the intestinal villi and microvilli that absorb nutrients is much higher than in the case of dry feeding (feeding only compound feed), and the feed intake and growth rate are significantly higher (announced in the May/June 2013 issue of Pig International). This liquid feeding system consists of a stirring tank, a stirrer, a transfer pump, a pipeline, various valves, and an intake tank, etc. A large amount of liquid feed is manufactured and stored in the stirring tank, then pumped by the transfer pump and supplied to the pigsty through a pipeline of about 300 to 500 meters. At this time, it is operated based on a centralized computer system because it requires various controls such as raw material supply, mixing, feeding amount adjustment, feeding time, feeding location, and washing method.

In this way, the conventional liquid automatic feeding system centrally manufactures liquid feed in a large stirring tank and then transports and supplies it to each area, so there is a disadvantage in that it is difficult to install and maintain because the overall system scale is large. In addition, if the length and slope of the transport pipeline or the transport height (height of the pigsty) is large, there is a problem in that there is difficulty in transport due to the limitation of the pump capacity, and it is difficult to apply to pigsty that is three stories above ground. And, since some of the water and mixed feed are fed into the mixing tank at the same time, the ratio of feed and water is not constant, so the quality of the liquid feed is not constant; if the feed and water are directly mixed, it is easily hardened over time; there is the inconvenience of having to re-supply wash water to the pipe to deal with the residual feed remaining inside the transport pipeline after the liquid feed is supplied; if the structure is such that the wash water is returned and mixed again with the residual feed, re-mixing may cause sanitary problems such as bacterial growth and wastewater treatment problems; if the mixed feed particles are large or float on water when stirred, the water and feed move separately, causing the transport pipe to become clogged; there is a limit to the feed transport capacity per hour; the size of the PVC pipe for liquid transport is small, making rapid transport difficult; and since a mixing tank and a wash water tank are required, a lot of kitchen room space is required.

Meanwhile, to resolve these shortcomings, liquid feeding is used in which feed and water are mixed in a mixing tank located on the top of individual feed troughs, the valve is opened, and the feed is spurted into the feed trough. In this case, the feed and water ratio must be approximately 1:3 to enable natural transport through the transport pipe. If the water amount is reduced, transport is not smooth, and if the water amount is large, there is a high probability that gastric ulcers will occur during the period when pigs consume liquid feed. In addition, there is the problem of having to clean the mixing tank frequently, and since the height of the liquid feeder equipment itself is high, the capacity of the feed tank for storing feed is small, so the feed must be refilled frequently.

Republic of Korea Patent No. 10-1201545 Republic of Korea Patent No. 10-1277590 Republic of Korea Patent No. 10-2134167

The present invention has been made to solve the problems of the conventional liquid automatic feeding system as described above, and the purpose of the present invention is to provide a liquid feeding feed and water mixing discharge hopper which, instead of transporting liquid feed through a long transport line, supplies feed and water mixed whenever necessary from the upper side of an individual feeding trough, while allowing the ratio of water to feed to be adjusted low, thereby reducing the probability of gastric ulcers in pigs, is easy to clean, has high space utilization, thereby increasing the capacity of the feed storage trough and extending the feed filling cycle, and prevents hardening by not directly mixing the feed and water, and supplies the feed and water evenly distributed, thereby enabling a uniform supply of liquid feed.

In order to achieve the above-mentioned purpose, the liquid feed and drinking water mixing discharge hopper according to the present invention comprises a hopper body having a lower portion opened so that dry feed can be stored therein and a portion of the dry feed can be discharged downward; and a distribution discharge portion that simultaneously discharges dry feed discharged through the lower opening of the hopper body and drinking water supplied from the outside in multiple directions through independent flow paths.

Here, the distribution outlet is configured as a hollow truncated cone having a cylindrical shape at the upper part and a tapered shape with a diameter that increases toward the lower part so as to be fitted into the lower opening of the hopper body, a water supply pipe for supplying water is provided on the outside, a tray, which is a plate member for temporarily receiving dry feed falling from the hopper body, is arranged at the center of the inside, and a plurality of tray brackets are provided at a predetermined interval along the circumference of the edge of the tray and interconnect the tray and the feed distribution outlet, a feed distribution outlet having a space formed between the inner surface of the tray and the feed distribution outlet and between adjacent tray brackets so that feed temporarily received in the tray can be discharged; The feed distribution outlet is coupled to the lower portion of the feed distribution outlet and is supplied through a water supply pipe provided on the outside of the feed distribution outlet, and is guided to the center and then uniformly distributed downward and discharged, and is configured in a circular disk shape and has a water supply inlet pipe provided on one side extending in the normal direction so as to be in communication with the water supply pipe of the feed distribution outlet, and the central portion is configured flat so as to be in contact with the lower surface of the tray of the feed distribution outlet, and a concave circulation path is formed on the outer periphery of the flat portion so as to be in communication with the water supply inlet pipe, and a plurality of water discharge ports are formed radially on the outer step of the circulation path so that the water supplied through the water supply pipe of the feed distribution outlet flows in through the water supply inlet pipe, fills the circulation path, and is discharged downward through the water discharge ports formed on the outer step of the circulation path.

And, it includes a lower cover coupled to the inside of the lower opening of the hopper body to receive dry feed from the hopper body and temporarily store it, and having a feed discharge port formed on the bottom surface so that the dry feed can be discharged downward; a shaft which is arranged vertically in the center of the inside of the hopper body, is arranged to penetrate the center of the lower cover, and is rotated by a motor (31); a first rotating blade which is formed on the outer surface of the shaft and moves the dry feed stored inside the lower cover as it rotates inside the lower cover and discharges it through the feed discharge port; and a second rotating blade which is provided at the lower end of the shaft penetrating the lower cover and discharges the dry feed put into the tray downward through the space between the tray and the inner wall of the outer casing as it pushes it by rotation.

According to the present invention as described above, since the liquid feed is individually manufactured in small quantities in individual feeding areas and supplied instead of being manufactured in large quantities in a centralized manner and then transported, it has the advantages of being simple in equipment, requiring little space, and being easy to manage. In addition, rather than manufacturing liquid feed by mixing a large amount of feed and drinking water at once, the feed and drinking water are mixed and directly injected into the feeding trough in small quantities whenever necessary, thereby lowering the ratio of feed to drinking water, thereby reducing the probability of gastric ulcers in pigs. In addition, since the drinking water is not supplied to a large feed trough, but rather the feed and drinking water are independently discharged into the feeding trough in a small mixing space, the feed and drinking water are not directly mixed, thus preventing the phenomenon of easy hardening and solidification, and since the feed and drinking water are supplied evenly and dispersed, it has the advantages of being able to supply a uniform liquid feed.

Hereinafter, the configuration and operation of the liquid feed mixing and discharging hopper according to the present invention will be described in detail with reference to the attached drawings and preferred embodiments.

As shown in FIGS. 1 to 5, the liquid feed mixing and discharging hopper according to the present invention includes a hopper body (100), a distribution and discharging section (200), a shaft (30), a motor (31), a lower cover (32), a stirring blade (34), a water supply section (40), a bridge prevention device (50), and a control section (60).

The hopper body (100) is a container in which dry feed is stored inside, and is configured in a tapered hopper shape with the upper and lower parts open and the diameter becoming smaller as it goes down, so that a large amount of dry feed stored inside can be sequentially discharged and supplied little by little to the distribution and discharge part (200) at the bottom. If necessary, an upper cover (not shown) can be placed on the upper part of the hopper body (100).

The distribution discharge unit (200) is a unit that simultaneously supplies dry feed discharged through the lower opening of the hopper body (100) and drinking water supplied from the water supply unit (40) to the lower feed tank (10; see FIG. 5). It is inserted and connected to the lower part of the hopper body (100), but is configured in a shape in which the upper and lower parts are open and the lower part is generally wider and tapered than the upper part.

More specifically, the distribution outlet (200) is configured to include a feed distribution outlet (210) and a negative distribution outlet (220), as illustrated in FIG. 3. The feed distribution outlet (210) is configured to have a shape corresponding to the shape of the lower portion of the hopper body (100) so that the upper portion can be fitted into the lower portion of the hopper body (100). More specifically, as illustrated in FIG. 2, the lower portion of the hopper body (100) is configured to have a cylindrical shape, and two guide protrusions (110) are vertically and parallelly formed to protrude from the outer surface, and the upper portion of the feed distribution outlet (210) of the distribution outlet (200) is also configured to have a cylindrical shape, and a guide groove (212) is cut and formed on one side so that the guide protrusions (110) can be inserted and fitted. Accordingly, the distribution outlet (200) is fitted into the lower part of the hopper body (100) and is firmly connected by preventing rotation by the guide projection (110) and the guide groove (212). For a more secure connection, the hopper body (100) and the feed distribution outlet (210) can be firmly connected by a separate fastener such as a bolt.

Meanwhile, the lower part of the feed distribution outlet (210) of the distribution outlet (200) is configured in a hollow truncated cone shape with a diameter that increases toward the bottom, and a water supply pipe (213) for supplying water is provided on the outside. As shown in Fig. 4, a tray (214) is arranged in the center of the inside. The tray (214) is a circular plate member that temporarily receives feed that falls from the upper hopper body (100), and is configured to have a diameter smaller than the diameter of the feed distribution outlet (210). A plurality of tray brackets (215) are provided on the edge of the tray (214) at predetermined intervals along the circumferential direction and interconnect the tray (214) and the feed distribution outlet (210), so that a space is formed between the inner surface of the tray (214) and the feed distribution outlet (210) and between the adjacent tray brackets (215), and as described later, feed temporarily stacked on the tray (214) falls into the space and is discharged into the feed trough (10).

Referring to FIGS. 3 and 4, a negative distribution outlet (220) is connected to the lower portion of the feed distribution outlet (210) of the distribution outlet (200). The negative distribution outlet (220) is intended to guide negative water supplied through a water supply pipe (213) provided on the outer side of the feed distribution outlet (210) to the central portion and then evenly distribute and discharge the water downward. The negative distribution outlet (220) is generally configured in a circular disk shape, and a negative water inflow pipe (222) is formed on one side to extend in a normal direction so as to communicate with the water supply pipe (213) of the feed distribution outlet (210). The above-mentioned negative water inlet pipe (222) is configured as a pipe body with an open upper portion, and the outer end communicates with the water supply pipe (213), and guides the negative water supplied through the water supply pipe (213) along the concave portion in the center to the negative water distribution outlet (220). The negative water distribution outlet (220) is configured in a disc shape, and the central portion is configured flat so as to be in contact with the lower surface of the tray (214) of the feed distribution outlet (210), and a concave circulation path (224) communicating with the negative water inlet pipe (222) is formed on the outer periphery of the flat portion, and a plurality of negative water outlets (226) are formed radially on the outer step of the circulation path (224). Through this configuration, the negative water supplied through the water supply pipe (213) of the feed distribution outlet (210) flows into one side of the negative water distribution outlet (220) through the negative water inflow pipe (222), fills the circulation path (224), and is discharged to the feed tube (10) arranged at the lower side through the negative water discharge ports (226) formed on the outer step of the circulation path (224). Here, since the negative water discharge ports (226) are arranged radially at regular intervals, the negative water is uniformly distributed and discharged in multiple directions. It is preferable that the feed distribution outlet (210) and the negative water guide (220) are made of a synthetic resin material and are mutually joined by a method such as heat fusion.

Meanwhile, the inside of the hopper body (100) includes a shaft (30), a lower cover (32), and a second rotating blade (34) to distribute and discharge dry feed.

The shaft (30) is vertically arranged in the center of the inside of the hopper body (20) and is rotated by the motor (31) connected to the upper side, thereby discharging dry feed to the lower side of the lower cover (32) described later. Here, the motor (31) is coupled with the shaft (30) while built into the motor casing and is fixedly supported by a motor bracket (31a) having a number of legs that branch radially from the center and are coupled to the inner surface of the hopper body (100).

The shaft (30), as shown in Fig. 2, is provided with a first rotary blade (30a) that is formed to protrude outwardly at a position spaced apart from the lower end by a predetermined distance. The first rotary blade (30a) moves and discharges dry feed as it rotates within the lower cover (32) described below. In addition, the lower end of the shaft (30) is rotatably coupled to the tray (214) inside the feed distribution outlet (210) and the center of the negative distribution outlet (220) after penetrating the lower cover (32).

The lower cover (32) is configured to be coupled to the inside of the lower opening of the hopper body (100) to temporarily store some dry feed supplied from the hopper body (100) and discharge the dry feed downward by the first rotary blade (30a) of the shaft (30). More specifically, as shown in FIG. 2, the lower cover (32) is configured in a cylindrical shape with an open upper portion and is inserted and coupled to the inside of the lower opening of the hopper body (100), and a through hole (32a) is formed in the center of the bottom surface so that the shaft (30) is inserted through it, and a plurality of feed discharge ports (32b) are formed radially on the outside of the through hole (32a).

A second rotary blade (34) is provided at the lower end of the shaft penetrating the lower cover (32). The second rotary blade (34) is configured to push dry feed fed into a tray (214) provided inside the feed distribution outlet (210) by rotation, thereby discharging the feed downward through the space between the tray (214) and the inner wall of the feed distribution outlet (210). A plurality of blades are provided radially, and the lower end of the shaft (30) is penetrated through the center, but is fixedly connected by a force-fit or key combination, and rotates together with the rotation of the shaft (30).

Referring to FIGS. 2 and 5, the lower cover (32) and the tray (214) are spaced apart from each other vertically, and a shaft (30) is rotatably connected to the lower cover (32) and the tray (214), respectively. Here, the first rotary blade (30a) of the shaft (30) is positioned on the inside of the lower cover (32) and rotates by the rotation of the shaft (30) to move dry feed temporarily stored inside the lower cover (32) in a circumferential direction, thereby causing the dry feed to be discharged and supplied in small amounts to the lower tray (214) through the feed discharge port (32b). Meanwhile, the second rotary blade (34) coupled with the shaft (30) is placed on the tray (214) and rotates to push the dry feed stacked on the tray (214) and move it outward, thereby discharging it downward through the space between the tray (214) and the inner wall of the feed distribution outlet (210).

In this way, the drinking water supplied through the water supply pipe (213) is distributed in multiple directions from the drinking water distribution outlet (220) through the drinking water inlet pipe (222) and is discharged into the feed trough (10) as shown in FIG. 5, and the dry feed is distributed in multiple directions by the second rotary blade (34) and is discharged into the feed trough (10). In this way, the dry feed and the drinking water are discharged into the feed trough (10) independently through different paths and meet and mix within the feed trough (10). Accordingly, since the dry feed and the drinking water are directly mixed in the hopper, the phenomenon of the liquid feed solidifying in the hopper can be prevented. Since the liquid feed is prevented from solidifying in the hopper, the inconvenience of having to frequently clean the hopper is eliminated. In addition, since the drinking water and the dry feed are evenly distributed and discharged in multiple directions, they are uniformly mixed with each other in the feed trough (10).

Meanwhile, the present invention further includes a water supply unit (40) to automatically supply drinking water to the water supply pipe (214) as shown in FIG. 5. The water supply unit (40) includes a filter, a water supply valve, a flow sensor, and a water supply hose, and supplies a certain amount of drinking water at a certain cycle under the control of the control unit (60). The configuration and operational relationship between the water supply pipe (214) and the control unit (60) are described in detail in the registered patent No. 10-2134167, so further description is omitted.

An anti-bridge device (50) is additionally provided on the lower side of the hopper body (100). In general, when a large amount of dry feed is stored inside the hopper body (100), the feed located in the lower layer is partially clumped or hardened as it is pressurized by the load of the feed located in the upper layer. This phenomenon is called a bridge phenomenon. When the bridge phenomenon occurs, the dry feed is in a hardened state, making it difficult to discharge, and it is also difficult to mix with water, making it difficult to smoothly manufacture liquid feed. In order to prevent this bridge phenomenon, a bridge prevention device (50) is provided. The bridge prevention device (50) is also described in detail in Patent Registration No. 10-2134167, so further description is omitted.

Meanwhile, the control unit (60) is a controller that controls the entire operation of the liquid feed and water mixing discharge hopper according to the present invention, and controls the operation of the motor (31) and the water supply unit (40) according to an operation start command so that the feed and water are discharged simultaneously.

Above, specific embodiments of the present invention have been described. However, the spirit and scope of the present invention are not limited to these specific embodiments, and those skilled in the art will understand that various modifications and changes can be made without changing the gist of the present invention. Therefore, the embodiments described above are provided to fully inform those skilled in the art of the present invention of the scope of the invention, and therefore should be understood to be exemplary and not restrictive in all respects, and the present invention is defined only by the scope of the claims.
