Description

The invention relates to agriculture, specifically to choppers for root and tuber crops, and can be used in individual farming (peasant) farms.

There is an analogue of a root and tuber shredder (RF patent for a useful model No. 152461, IPC B02C 18/14, 2014) containing a frame, a loading hopper fixed on it, a cylindrical body with reflectors and outlets, opposite which replaceable knife walls are installed, where the processed material is fed to the knife walls using a centrifugal rotor through three guide tubes located at an angle of 120 ° relative to each other and making a rotational movement in a cylindrical body with three outlets, opposite which replaceable knife walls are installed, allowing to obtain slices of various thicknesses, characterized in that additionally contains a vibrator-shaker and a drum-type dispenser, while the vibrator-shaker is located on the side of the feed hopper; the dispenser is located between the feed hopper and the cylindrical body, while the dispenser has a rocker valve in the lower neck, and the outlets of the cylindrical body are equipped with plugs.

The disadvantage of the known grinder is the complexity of adjusting some of the operating and design parameters of the centrifugal rotor, including the lack of the ability to adjust the rotation speed, which reduces the efficiency of the cutting process and degrades the quality of the finished product. Increased rotor rotation noise requires special sound protection for personnel.

For the prototype, a fruit and vegetable shredder was chosen (RF patent for a useful model No. 129845, IPC B02C 18/14, 2013), containing a frame, a housing fixed to it with a grinding chamber, a loading mouth and an unloading window, as well as a gear motor with a drive shaft , a crank mechanism driven by a motor-reducer and moving the knife wall along the guides inside the body towards the counter-counter support.

The disadvantage of the known grinder is that the cutting of the processed material in the grinding chamber is carried out by forcing the root crops through the working bodies of the knife wall, which leads to an increase in the energy consumption of the process, while after the completion of the work the product remains on the knives, which requires manual cleaning by the operator, which is unsafe.

The essence of the invention is as follows.

The objectives of the invention are to increase the productivity of the grinder, the level of work safety, as well as improve the working conditions of personnel by carrying out a continuous process of crushing root tubers without getting stuck in the upper part of the grinding chamber and clogging the gap between the blades of the grinder's knife wall.

The technical result is the elimination of clogging of the gap between the blades of the cutter wall of the chopper during chopping of fruit and vegetable products, stuck root and tuber crops in the upper part of the chopping chamber, as well as manual cleaning of the blades at the end of work and thereby increasing the productivity of the chopper, increasing the level of work safety, as well as improving working conditions staff.

The specified technical result is achieved by the fact that in a root and tuber grinder containing a frame, a housing fixed to it with a grinding chamber, a loading neck and an unloading window, a gear motor with a drive shaft and a crank mechanism moving the knife wall along the guides inside the housing towards the counter-shearing support, According to the invention, the knife wall is provided with a restrictive plate fixed on its upper end, the counter support interacting with the knife wall knives is equipped with a comb, and the loading neck is equipped with an adjusting flap.

The invention is illustrated by drawings.

FIG. 1 shows a general diagram of a root and tuber grinder; in fig. 2 shows a top view AA of FIG. 1.

The device contains a frame 1, a housing 2 fixed on it with a grinding chamber 3 of square or rectangular cross-section, a loading throat 4 with an adjusting flap 5, an electric motor 6, a gear motor 7, a crank mechanism 8, knives 9 in the knife wall 10, which makes a reciprocating - translational movements along the guides (not shown in the figures) inside the body together with the limiting plate 11. The plate 11 is fixed on the upper end of the knife wall 10, which prevents root and tuber crops from getting stuck in the upper part of the grinding chamber during grinding. The counter-cutting support 12 is equipped with a comb 13, which ensures self-cleaning of the knives 9. There is an unloading window 14.

The equipment of the knife wall 10 with a restrictive plate 11, located at its upper end from the side of the loading neck, does not allow root and tuber crops to get stuck during grinding in the upper part of the installation.

The equipment of the counter backing 12 with a comb 13 makes it possible to exclude clogging of the gap between the knives 9 of the knife wall 10 of the grinder during chopping of fruits and vegetables.

The device works as follows.

The operator loads the root crops into the loading neck 4 with an adjusting flap 5, which limits their supply, without creating obstacles for the root crops when entering the grinding chamber 3. The crank mechanism 8 moves the knife wall 10 along the guides (not shown in the figure) inside the body 2 towards counter support 12 with a comb 13. To increase the productivity and quality of work in the grinding chamber 3, the knife wall 10, with the knives 9 fixed in it, reciprocates along the guides inside the housing 2, together with the limiting plate 11, which prevents it from getting stuck root crops when grinding in the upper part of the installation. Slices of the required thickness are removed through the discharge window 14 into the container tray. Self-cleaning of the knives 9 occurs upon contact with the comb 13 of the counter-support 12, which excludes manual cleaning of the knives, increases the level of work safety and improves the working conditions of the personnel.

Thus, the use of the proposed device in agricultural production will allow eliminating the clogging of the gap between the blades of the chopper's knife wall during chopping of fruits and vegetables, stuck root and tuber crops in the upper part of the chopping chamber, as well as manual cleaning of the knives at the end of work and thereby increase the productivity of the chopper, increase the level of safety work, as well as improve the working conditions of personnel.
