[0002] In the production of selenium-rich feed, crushing equipment is needed to refine the selenium-rich feed raw materials. The crushing equipment can cut the feed into crushed materials or powder, which is convenient for feed processing and mixing, and improves the taste of livestock feed.

[0003] Because the humidity of selenium-rich feed raw materials is too high, the existing feed crushing equipment often causes the raw materials to adhere to the crushing roller during crushing. The adhesion of the raw materials to the crushing roller will cause the rotation of the crushing roller to be obstructed, reducing its rotation speed and crushing efficiency, which will not only prolong the time of the entire crushing process, but also affect the overall efficiency of feed production. At the same time, the adhesion of the raw materials will not only affect the operation of the crushing roller, but may also increase the friction between it and other parts of the equipment, thereby accelerating the wear and aging of the equipment.

[0030] The box body 1 is provided with a crushing and screening component 2, which includes a screening plate 21 installed on the inner side of the box body 1. The screening plate 21 includes a fixed frame, a screen installed on the inner side of the fixed frame and a mounting seat 211. The mounting seat 211 is located at the center of the fixed frame 1. The crushing and screening component 2 can perform preliminary screening on the feed and separate feed of different particle sizes, thereby improving the quality of the crushed feed and ensuring uniform particle size. A crushing knife roller 22 is movably connected to the screening plate 21. The crushing knife roller 22 can rotate and cut the feed to achieve the crushing function. The crushing knife roller 22 is hollow. The crushing knife roller 22 is movably connected to the mounting seat 211 through a rotating shaft. A transmission shaft 23 is installed at the end of the crushing knife roller 22 away from the screening plate 21. The transmission shaft 23 can drive the crushing knife roller 22 to rotate. The transmission shaft 23 is hollow. A partition 24 connected to the box body 1 is provided on the outside of the transmission shaft 23. A motor 25 is fixedly connected to the partition 24. A gear set 26 is provided between the motor 25 and the transmission shaft 23. The gear set 26 includes two mutually meshing bevel gears. The gear set 26 transmits power and adjusts the speed to adapt to different crushing requirements.

[0031] The crushing and screening element 2 is provided with a heating box 3, and a fan 4 is installed on the side wall of the heating box 3. The side wall of the box body 1 is provided with a through hole connected to the air inlet of the fan 4, and the exhaust end of the fan 4 is connected to the side wall of the heating box 3. A heating plate 5 is installed on the inside of the heating box 3. The heating plate 5 includes a heat-resistant plate and a heating wire installed on the surface of the heat-resistant plate. The surface of the heat-resistant plate is provided with a plurality of air outlet holes. The heating plate 5 is installed on the inside of the heating box 3 to heat the air. Under the blowing of the fan 4, the internal temperature of the box body 1 is increased, the humidity of the feed is reduced, and adhesion is prevented. At the same time, the fan 4 can ensure that the feed is heated evenly. The end of the heating box 3 away from the fan 4 is connected with a connecting pipe 6;

[0032] A water pump 7 is installed on the heating box 3. The water pump 7 is convenient for cleaning the inside of the box body 1 after the crushing operation is completed. The drainage end of the water pump 7 is connected to the connecting pipe 6 through a water pipe 701. The connecting pipe 6 and the water pipe 701 are respectively equipped with a control valve 702. The control valve 702 can control the flow and start and stop of the heated air or flushing water. The setting of the control valve 702 is convenient for the operator to adjust according to actual conditions, thereby improving the flexibility and controllability of the equipment. The water inlet end of the water pump 7 passes through and extends to the outside of the box body 1, and the drainage end of the water pump 7 is connected to the connecting pipe 6.

[0033] A docking seat 8 is installed on the inner wall of the box body 1, and the docking seat 8 is connected to an insertion tube 801 at one end close to the transmission shaft 23.

The rotating sealing ring 802 fits against the inner wall of the transmission shaft 23. The setting of the docking seat 8 ensures that the flushing water and hot air can smoothly enter the interior of the box body 1. The docking seat 8 is connected to the connecting pipe 6 and the crushing and screening component 2. The crushing and screening component 2 is connected to a nozzle 9, which can spray flushing water to clean the interior of the box body and the crushing and screening. The number of the nozzles 9 is several, and the several nozzles 9 are equidistantly distributed on the outside of the crushing knife roller 22.

[0034] Taking selenium-rich feed as an example, the selenium-rich feed to be crushed is put into the box 1. The selenium-rich feed is selected because with the improvement of consumers' health awareness, the demand for selenium-rich food is increasing. Animal products fed with selenium-rich feed are favored by the market due to their unique nutritional value. Therefore, selenium-rich feed is selected as an example to better demonstrate the market application prospects of feed processing technology. The steps of crushing the selenium-rich feed are as follows:

[0035] The selenium-rich feed to be crushed is fed into the box body 1 through the feed hopper 101. The selenium-rich feed to be crushed is larger than the aperture of the screening plate 21, and the selenium-rich feed to be crushed is drained through the aperture of the screening plate 21.

[0036] At the same time, the heating plate 5 in the heating box 3 heats the air, the fan 4 draws in the external air and heats it through the heating box 3, opens the control valve 702 on the connecting pipe 6, closes the control valve 702 on the water pipe 701, and the hot air passes through the connecting pipe 6, the docking seat 8 and the transmission shaft 23, and then blows into the interior of the box 1 through the nozzle 9 on the crushing roller 22;

[0037] The heated air increases the temperature inside the box 1 and reduces the humidity of the feed;

[0038] The motor 25 is started, and the power is transmitted to the transmission shaft 23 through the gear set 26. The transmission shaft 23 drives the crushing roller 22 to rotate. The blades on the crushing roller 22 cut and crush the feed. The crushed feed is discharged through the screening plate 21 and the discharge pipe 102. The screen of the screening plate 21 separates feeds of different particle sizes to ensure that the particle size of the crushed feed is uniform.

[0039] After the feed is crushed, the control valve 702 on the control connecting pipe 6 is closed, the control valve 702 on the water pipe 701 is opened, and the water pump 7 is started. Water passes through the connecting pipe 6, the docking seat 8 and the transmission shaft 23, and then sprays flushing water through the nozzle 9 on the crushing knife roller 22 to clean the inside of the box 1 and the crushing and screening element 2.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
