The belt 6 here will drive the follower wheel 1 8 and the follower wheel 2 9 to rotate together under the drive of the main wheel 5.

[0026] Reference Figure 2-3The four sides of the outer side of the rotating shaft are fixedly connected with a scraper box 10, and a groove 11 is opened inside the scraper box 10. A plurality of springs 12 are arranged inside the groove 11. The spring 12 here is used to provide elastic potential energy. The inner wall of the groove 11 is slidably connected with a scraper 13. The scraper 13 here can be squeezed more tightly with the inner wall of the barrel 2 under the elastic potential energy provided by the spring 12, and the effect of cleaning the inner wall grass is better, ensuring the cleanliness of the inside of the barrel 2, preventing the rotting of the retained grass and the breeding of bacteria, etc., and ensuring the health of livestock cattle. The spring 1 One end of the spring 12 is fixedly connected to one side of the inner wall of the groove 11, and the other end of the spring 12 is fixedly connected to one side of the scraper 13.

The outside of the scraper 13 is slidably connected to the inner wall of the scraper box 10, and the outer wall of the scraper 13 contacts the inner wall of the barrel 2. The left side of the barrel 2 is fixedly connected with a discharge port 14, and the discharge port 14 here is used to transport the cut grass out, and then the staff can collect the cut grass.

[0027] Reference Figure 2 and Figure 4 , the left inner wall of the barrel 2 is fixedly connected with a dredging component, and the dredging component here is used to prevent the discharge port 14 from being blocked. The dredging component includes a motor 2 15, and the left side of the motor 2 15 is fixedly connected to the left inner wall of the barrel 2, and the driving end of the motor 2 15 is fixedly connected with a turntable 16. When the motor 2 15 is started, it will drive the turntable 16 to rotate under the drive of electricity, and the right outer side of the turntable 16 is rotatably connected with a short rod 17. When the turntable 16 rotates, it will drive the short rod 17 thereon to move together, and the other end of the short rod 17 is rotatably connected with a main shaft 18, and when the short rod 17 moves, it will drive the main shaft 18 to reciprocate back and forth, and the outside of the main shaft 18 is slidably connected to the rear end inner wall of the discharge port 14, and the outside of the main shaft 18 is slidably connected to a support block 19, and here The support block 19 can support the movement of the main shaft 18 so that it can make a linear translational motion, that is, a limiting effect. The bottom end of the support block 19 is fixedly connected to the bottom end of the left inner wall of the barrel 2. The front end of the main shaft 18 is fixedly connected with a tamping head 20. The tamping head 20 here is in direct contact with the cut grass. Through continuous reciprocating motion, the discharge port 14 is unblocked to prevent the accumulation of grass here. The rear end of the tamping head 20 is in contact with the inner wall of the discharge port 14. The front end of the barrel 2 is fixedly connected with an operating table 21. The operating table 21 here is used to control the entire machine. The rear end bottom of the operating table 21 is fixedly connected to the top front part of the frame 1, and the rear end of the operating table 21 is fixedly connected to the front end of the feed port 3. The feed port 3 and the frame 1 here can provide additional support force to the operating table 21 to make it more stable.

[0028] Working principle: When using this device, the staff can first place the grass to be cut on the feed port 3. The feed port 3 here is equipped with multiple blades to cut the grass, and then start the motor 4 at the bottom of the frame 1. Then the motor 4 will drive the main wheel 5 to rotate under the drive of electricity. Because the outside of the main wheel 5 is provided with a belt 6, and the belt 6 is also provided on the outside of the slave wheel 1 8 and the slave wheel 2 9, the main wheel 5 will drive the belt 6, the slave wheel 1 8 and the slave wheel 2 9 to rotate together when it rotates. Here, the slave wheel 1 8 will drive the conveying roller 7 to rotate when it rotates, and then the slave wheel 1 8 will transport the cut grass placed inside the feed port 3 to the inside of the barrel 2, and then the cut grass will be further transported to the scraper box 10. Under the rotation of the slave wheel 2 9, it will drive the scraper box 10 to rotate together, so as to transport the cut grass along the scraper box 10 to the discharge port 14. The function of the spring 12 here is to transport the scraper box 10 When feeding the grass, the scraper 13 can be made to fit more tightly with the inner wall of the barrel 2, and the fine grass attached to the inner wall of the barrel 2 can also be scraped off to prevent it from being stagnant on the inner wall of the barrel 2 for a long time and causing decay, further affecting the freshness of the grass, and thus causing harm to the health of livestock cattle. When discharging, the discharge port 14 will inevitably be blocked. At this time, the motor 2 15 can be started. The motor 2 15 will drive the turntable 16 to rotate under the drive of electricity. When the turntable 16 rotates, it will drive the short rod 17 thereon to move. The short rod 17 further drives the main shaft 18 thereon to move back and forth. The support block 19 here is to support the sliding of the main shaft 18 and at the same time limit its sliding range so that it always makes a linear translation motion. At this time, the main shaft 18 will drive the pounding head 20 at the head to reciprocate, so that the pounding head 20 can reciprocate and pound the cut grass to prevent the grass from being blocked.
