Description

A kind of fertilizer distribution equipment

technical field

The invention relates to the technical field of agricultural machinery, in particular to a fertilizer distributing equipment.

Background technique

Fertilizer distributing equipment in the prior art generally carries out the transportation of chemical fertilizer materials by fan transportation, screw transportation, bucket lifting and other methods. Fan conveying designs the fertilizer distribution equipment as a closed system, uses the operation of the fan to generate a vacuum negative pressure in the closed fertilizer distribution equipment pipeline, and sucks the fertilizer material into the storage hopper or discharge hopper for subsequent feeding or discharging operate. The screw conveyor uses the motor as the power source, and the screw blade rotates in the pipeline to push the fertilizer material to the storage hopper or discharge hopper. The bucket is lifted through the bucket as a carrier, and the motor drives the steel rope or chain to drive the bucket to lift the fertilizer material to the storage hopper or unloading hopper.

However, the above-mentioned delivery method has the following disadvantages:

Fan transportation has very high sealing requirements for storage hoppers, discharge hoppers and pipeline systems. As long as there is air leakage, the transportation efficiency of materials will be greatly reduced, the processing cost is high, the processing difficulty is high, the installation is difficult, and the long-term operation reliability of the equipment is poor. The power components conveyed by the fan generally use high-speed fans, air compressors, motors, etc., which consume a lot of power. When conveyed by wind, it is difficult to convey pure powder materials or materials with a lot of powder. The powder materials will generate dust under the drive of high-speed wind. During production, fertilizer materials are first loaded into the lower station hopper on the ground, and then transported upwards to the upper station storage hopper through pipelines, and the material transportation efficiency is extremely low. Fan power conveying materials requires a lot of electrical components and electric switching valves to control the fan air system. There are many control points. As long as some of the control components are damaged, the entire fertilizer distribution machine will not work normally, and it is easily damaged and has a high failure rate.

Screw conveying relies on the friction between the material and the screw blade to push the material to be transported in the pipeline. If the screw processing strength is not enough, the screw is easy to break, and the selection of the motor is unreasonable, and it is easy to cause overload and tripping. The extrusion force generated by the screw blade and the material during the conveying process can easily destroy the particle integrity of the material. Fertilizer raw materials are all corrosive, and the requirements for the material of the screw rod are very strict, and the moving parts are easily corroded. In a humid environment, the powdery material is easy to agglomerate, causing the screw to be stuck and cannot continue to work. Each feeding screw needs to be equipped with a motor as power, and the energy consumption of the whole fertilizer distributing equipment is relatively large. During production, fertilizer materials are first loaded into the lower station hopper on the ground, and then transported upwards to the upper station storage hopper through the screw, and the material transportation efficiency is extremely low. There are more control points, more control components are required, and the frequent work of control components leads to a higher failure rate.

For the fertilizer distribution equipment that is lifted by the bucket, since the fertilizer distribution materials are corrosive, the ropes and chains of the bucket are easily corroded, and mechanical failures are very easy to occur. After a period of operation, the equipment needs to spend a lot of time on maintenance. In addition, the lifting method of the bucket also has the disadvantages of high energy consumption, low material conveying efficiency, and many control points, resulting in high failure rate.

Moreover, the existing fertilizer distributing equipment has the disadvantage of being inconvenient to transport because of its large volume.

For example, the conveying device 1 adopts a conveyor belt, and if a worker accidentally touches the conveyor belt, he may be involved in the moving conveyor belt. By providing a slideway mechanism under the other end 12 of the conveying device, the whole bag of fertilizer materials falls from the other end 12 of the conveying device to the slideway mechanism, and then slides down to the bottom surface of the upper station platform 2, thereby preventing the staff from interacting with the conveying device. 1 contact.

As shown in FIG. 4 , the upper station platform 2 is provided with a control panel 22 for controlling the conveying device 1 . Specifically, the control panel 22 is provided with keys for controlling the conveying speed, starting and stopping of the conveying device 1 . Since the staff on the upper station platform 2 are the main operators for feeding materials, it is necessary to set the control panel of the conveying device on the upper station platform and be controlled by the staff on the upper station platform 2 to avoid excessive conveying speed of the conveying device. Fast, too late to feed and lead to the accumulation of fertilizer materials. In addition, the upper station platform 2 has limited operating space and a high height. Operation control on the upper station platform 2 can avoid sudden failures and safety accidents.

When the upper station platform is provided with a bottom surface, a feeding port 23 is provided on the bottom surface of the upper station platform 2 , and the feeding port 23 is connected to the material storage device 3 . The feeding port 23 can be directly connected to the material storage device, or connected to the material storage device through an opening or a channel, or connected to the material storage device through an opening or a channel provided on the top wall of the working chamber. For example, the storage bin of the material storage device 3 is provided with a first opening (not shown in the figure), and the first opening is arranged opposite to the feeding port 23, and the fertilizer material falls into the storage bin through the feeding port 23 and the first opening successively. Inside. In addition, when the top wall of the storage device 3 is used as the bottom surface of the upper station platform, that is, when the bottom surface of the upper station platform is omitted and replaced by the top wall of the storage device, the storage device 3 The top wall is provided with a feeding port. The embodiment of the present invention is mainly described in the case that the bottom surface of the above station platform is formed by the top wall of the material storage device.

A partition 231 is provided at the position of the feeding port 23, and each feeding port 23 is separated by the partition 231, so as to prevent different types of fertilizer materials from splashing to other feeding ports.

The other side of the operating area 24 is connected to the climbing device 81 , which is convenient for the staff to climb to the upper station platform 2 from the climbing device 81 . As shown in Figure 6, each feeding port 23 is arranged around the periphery of the operating area 24, thereby saving as much space as possible for the operating area 24, and the staff in the central position are also convenient to throw fertilizer materials to the surrounding feeding ports. Not much moving around is required.

Fig. 7 is a top view structure schematic diagram of the material storage device of the first embodiment of the present invention, as shown in Fig. 7, the material storage device 3 of the first embodiment of the present invention is surrounded by six storage bins 31 with the same external structure in the middle of the material storage device Composition of vertical lines. Each storage bin 31 is used to store one kind of fertilizer material, therefore, the fertilizer distributing device of the embodiment of the present invention can simultaneously process and produce six kinds of fertilizer materials. In addition, the present invention does not limit the number of storage bins, and the number of storage bins can be increased or decreased according to actual production needs.

Fig. 8 is a schematic diagram of the three-dimensional structure of the storage bin in Embodiment 1 of the present invention, and Fig. 9 is a schematic diagram of the stereoscopic structure of the storage bin in Embodiment 1 of the present invention without the first valve, as shown in Fig. 8 and Fig. 9 , the storage bin The silo is provided with a feeding port 311 (the situation on the bottom surface of the upper station platform is omitted), a feeding port 312 and a first valve 313 .

The feeding port 311 of the storage bin is arranged on the outer edge of the top wall 314 of the storage bin, and the feeding port 312 is arranged at the bottom of the storage bin. The first valve 313 is located at the feeding port 312 . The adjacent first side walls 315 between the storage bins are arranged vertically and cooperate with each other, so that a plurality of storage bins surround the vertical line of the storage device and form a storage device. As shown in FIG. 7 , the top surface of the storage bin 31 is triangular, and the six storage bins 31 are assembled into a storage device 3 with a hexagonal top surface. The discharge port 312 of each storage bin is offset to the vertical line of the material storage device 3 , that is, the discharge port of each storage bin 312 is arranged around and close to the vertical line of the material storage device 3 . Because the volume of the storage bin 31 is much larger than the metering device 4 below, it is necessary for the feeding port 312 to move closer to the center so that each feeding port 312 is located above the metering device 4, otherwise the metering device 4 is too large due to the top surface area. The side wall also needs to meet the setting of the angle of repose, which will inevitably lead to an oversized metering device, adding unnecessary space and height to the fertilizer distribution equipment as a whole.

Fig. 10 is a schematic diagram of the upward structure of the storage bin omitting the first valve according to Embodiment 1 of the present invention. The projection of 311 on the ground and the projection of the feeding port 312 on the ground do not overlap with each other. The second side wall 316 of the storage bin extends from the feeding port 311 to the feeding port 312 , and the projection of the feeding port 311 on the ground falls within the projection range of the second side wall 316 on the ground. The fertilizer materials input from the feeding port 311 first all fall to the second side wall 316 , and then slide into the feeding port 312 from the second side wall. In this way, the chemical fertilizer material is prevented from falling directly to the feeding port 312, and when the material is fed to the metering device 4, the chemical fertilizer material will not directly impact the metering device, reducing the adverse effect on the weighing accuracy. The second side wall 316 conforms to the setting of the angle of repose, so as to prevent the fertilizer material from hanging on the wall. The second side wall 316 in the figure is a planar structure. In addition, the second side wall 316 can also be set as an arc-shaped wall structure, and its arc-shaped wall is tangent to the adjacent side wall, which can reduce the edges and corners formed by the contact between the planes. , to reduce the bridging phenomenon of fertilizer materials.

Fig. 11 is a schematic diagram of the three-dimensional structure of the metering device in Embodiment 1 of the present invention, Fig. 12 is a schematic diagram of the bottom view of the metering device in Embodiment 1 of the present invention, and Fig. 13 is a schematic diagram of the stereoscopic structure of the metering mechanism in Embodiment 1 of the present invention, as shown in Fig. As shown in 11 to 13 , the metering device 4 of the embodiment of the present invention includes: three metering mechanisms 41 . Adjacent side walls between the respective metering mechanisms 41 are arranged vertically and cooperate with each other, so that the three metering mechanisms 41 can be closely fitted together around the vertical line of the metering device to save space. Each metering mechanism 41 is arranged opposite to the two storage bins 31, and each metering mechanism 41 weighs the fertilizer materials in the two storage bins 31 in sequence, that is, firstly, the fertilizer materials in one storage bin 31 are fed to the other. The metering mechanism 41 below performs metering, and when the fertilizer material in the metering mechanism 41 reaches a preset weight, the feeding of the storage bin 31 is stopped, and the feeding of another storage bin 31 above the metering mechanism 41 is started simultaneously. For feeding and conveying, the weighing mechanism 41 weighs the fertilizer material in the other storage bin 31 . The three metering mechanisms 41 perform metering at the same time, and each metering mechanism 41 works independently. If there is only one measuring mechanism to weigh the fertilizer materials in each storage silo sequentially, the weighing step will take a lot of time, and the stirring device must wait for the weighing to be completed before stirring, resulting in a significant drop in fertilizer distribution efficiency. However, if each storage bin is equipped with a metering mechanism, the overall volume of the metering device will be too large, and the additional metering mechanism will increase the cost of the fertilizer distribution equipment.

The top wall of the metering mechanism 41 is provided with a second opening 411 , the bottom of the metering mechanism is provided with a third opening 412 , and the third opening 412 is provided with a second valve 413 . The second opening 411 is opposite to the feeding opening 312 . As shown in Figure 12, the third opening 412 of each metering mechanism is offset to the vertical line of the metering device, that is, around and close to the vertical line of the metering device 4, the principle of which is the same as that of the discharge port of the storage bin. similar and will not be repeated here. Referring to Fig. 9, a first dust-proof mechanism 317 is provided between the feeding port 312 and the second opening 411. For powdery chemical fertilizer materials, a certain amount of dust will still be generated if the material is transported by gravity. A dust-proof mechanism 317 is provided between the mechanisms to prevent dust from flying out.

Wherein, a weighing sensor is provided in the measuring mechanism, and the weighing sensor can adopt a resistance strain type weighing sensor. When the weight of the chemical fertilizer raw material in the measuring mechanism 41 increases, the measuring mechanism 41 sinks, resulting in deformation of the resistance strain type weighing sensor. , and then output the weight signal of the fertilizer raw material.

The silo 31 is in an inverted conical shape, and the surface of the entire storage silo is arc-shaped, without edges and corners formed by contact between planes. The formation of edges and corners can easily bridge the accumulated materials and affect the flow properties of the materials. Although the arc-shaped inner wall can effectively improve the fluidity of granular fertilizer materials, for powdery or high-humidity fertilizer materials, bridging may still occur, affecting the free flow of fertilizer materials. Therefore, a first screw mechanism 32 is vertically provided in the storage bin 31 to destroy the bridging structure of the powdery or high-humidity fertilizer materials in the storage bin, and make the fertilizer materials loose by stirring to facilitate flow.

The first screw mechanism 32 includes: a first screw assembly, a second screw assembly and a vertically arranged first rotating shaft 321 . The first helical component and the second helical component are arranged on the first rotating shaft and are arranged in opposite directions. The radius of the first helical assembly is greater than the radius of the second helical assembly. The first screw assembly rolls the fertilizer material downwards and pushes the fertilizer material to the outlet 312 .
