[0032] Refer to Figure 1 and Figure 2, a grass feed chopping device, including a device body 1, a feed inlet 101 is provided on the device body 1, a pressure reduction structure 2 is provided above the feed inlet 101, the pressure reduction structure 2 includes two pretreatment hoppers 201 located above the feed inlet 101 and an air extraction pump 205 installed on the device body 1. A first arc-shaped pipe 206 is connected between the two pretreatment hoppers 201. The suction end of the air extraction pump 205 is installed with a first hose 208. The other end of the first hose 208 is connected with a first connecting pipe 207. The other end of the first connecting pipe 207 is connected to the inside of the first arc-shaped pipe 206. Filter nets 209 are installed in both pretreatment hoppers 201. The two filter nets 209 are respectively attached to both ends of the first arc-shaped pipe 206. First butterfly valves 202 and second butterfly valves 203 are installed on both pretreatment hoppers 201. According to the above technical solution, specifically, keep the first butterfly valve 202 in a closed state, pour the grass feed raw material into one of the pretreatment hoppers 201, and then keep the second butterfly valve 203 in a closed state. At this time, start the air extraction pump 205, so that the air in the pretreatment hopper 201 is discharged through the first arc-shaped pipe 206, then enters the first connecting pipe 207, and then enters the first hose 208, and finally is discharged to the outside, so that the air pressure in the pretreatment hopper 201 is reduced, thereby reducing the moisture of the grass feed raw material and weakening the firmness of the internal fibers. Then, open the first butterfly valve 202 and the second butterfly valve 203, so that the grass feed raw material in the pretreatment hopper 201 falls into the feed inlet 101, and the grass feed raw material is cut by the cutter in the device body 1, achieving the effect of being easier to cut the grass feed raw material and preventing the feed from winding around the cutter during feeding.

[0033] Refer to Figure 1 , switches 204 are installed on both pretreatment hoppers 201. The two switches 204 are electrically connected to the corresponding first butterfly valves 202 and second butterfly valves 203.

The cold outlet end of the refrigerator 401 is installed with a second flexible pipe 404. The other end of the second flexible pipe 404 is connected to the second connecting pipe 403. When the first butterfly valve 202 and the second butterfly valve 203 are in the closed state and there is grass feed raw material in the pretreatment hopper 201, start the refrigerator 401, so that the cold air enters the second arc-shaped pipe 402 through the second connecting pipe 403, and then enters the pretreatment hopper 201 from the second arc-shaped pipe 402, which is used to cool the grass feed raw material, so that the grass feed raw material becomes brittle while maintaining moisture, and further improves the speed at which the grass feed raw material is broken and cools the internal cutter of the device body 1 subsequently.

[0037] Refer to Figure 1 and Figure 4 , two second solenoid valves 405 are installed on the second arc-shaped pipe 402. The second solenoid valves 405 are used to control the cold air to be discharged only into the pretreatment hopper 201 with grass feed raw material.

[0038] Working principle:

[0039] For this grass feed chopping device, start the air extraction pump 205, so that the air in the pretreatment hopper 201 is discharged through the first arc-shaped pipe 206, then enters the first connecting pipe 207, and then enters the first flexible pipe 208, and finally is discharged to the outside, thus reducing the air pressure in the pretreatment hopper 201, further reducing the moisture of the grass feed raw material and weakening the firmness of the internal fibers. Then, open the first butterfly valve 202 and the second butterfly valve 203, so that the grass feed raw material in the pretreatment hopper 201 falls into the feed inlet 101, and the grass feed raw material is cut by the cutter in the device body 1, achieving the effect of more easily cutting the grass feed raw material and preventing the feed from winding around the cutter during feeding.

[0040] For the grass feed chopping device, with the first butterfly valve 202 and the second butterfly valve 203 in the closed state and there being grass feed raw materials in the pretreatment hopper 201, start the refrigerator 401 so that cold air enters the second arc-shaped pipe 402 through the second connecting pipe 403, and then enters the pretreatment hopper 201 from the second arc-shaped pipe 402 to cool the grass feed raw materials, thereby making the grass feed raw materials brittle while maintaining moisture, further improving the speed at which the grass feed raw materials are broken, and cooling the cutter inside the subsequent device body 1.
