[0027] Combined with Figure 3 and attached Figure 4 As shown, the crushing mechanism 6 includes a stirring disc 63 and a knife disc 66 rotatably arranged inside the crushing box 2, a plurality of stirring rods 64 are evenly arranged on the inner side of the stirring disc 63, a plurality of shredding knives 68 are evenly arranged on the inner side of the knife disc 66, the stirring rods 64 and the shredding knives 68 are staggered, a plurality of turning plates 65 are arranged at the inner edge of the stirring disc 63, the crushing box 2 is tilted, and a feed pipe 21 connected to the feed box 3 is provided at the eccentric upper part, and the stirring disc 63 is provided with a cutting knife 69 on the side of the groove.
[0028] Working principle of the crushing mechanism 6: the grass enters the crushing box 2 through the feed box 3 and the feed pipe 21. Under the drive of the driving mechanism 5, the stirring disc 63 and the knife disc 66 rotate in opposite directions. When the stirring disc 63 rotates, the cutting knife 69 will cut the grass that has just entered the crushing box 2 into segments. After the grass segment enters the area between the stirring disc 63 and the knife disc 66, it is chopped by the chopping knife 68 on the knife disc 66. In this process, the stirring rod 64 is driven by the stirring disc 63 to stir the grass. The turning plate 65 turns over the grass accumulated at the screen 22 to prevent the screen 22 from being blocked by the material, and turns over the long grass to the cutting space for re-chopping. The inclined crushing box 2 prevents excessive accumulation of grass at the screen 22, and the grass can rotate with the knife disc 66.
[0029] Combined with Figure 3 and attached Figure 4 As shown, the driving mechanism 5 includes a motor 51, and an bevel gear 1 52 is provided on the output end of the motor 51. A coaxially connected bevel gear 2 54 and a bevel gear 3 55 are rotatably provided in the base 1. The bevel gear 1 52 is meshed with the bevel gear 2 54. A main shaft 61 that is rotatably matched with the crushing box 2 is provided at the axis of the stirring plate 63. An bevel gear 4 62 is provided at one end of the main shaft 61 through the axial through hole of the cutter disc 66. An bevel gear 5 67 is provided on the rear side of the cutter disc 66. The bevel gear 3 55 is meshed with the bevel gear 4 62 and the bevel gear 5 67 respectively.
[0030] Working principle of driving mechanism 5: motor 51 drives bevel gear 1 52 to rotate, and bevel gear 1 52 is meshed with bevel gear 2 54 to transmit transmission, so that bevel gear 2 54 rotates, and bevel gear 3 55 coaxially connected with bevel gear 2 54 rotates, driving bevel gear 4 62 and bevel gear 5 67 meshed with bevel gear 3 55 to rotate, and bevel gear 4 62 and bevel gear 5 67 rotate in opposite directions, bevel gear 4 62 drives stirring plate 63 to rotate through main shaft 61, and bevel gear 5 67 drives cutter disc 66 to rotate, so that stirring plate 63 and cutter disc 66 rotate synchronously and in opposite directions.
[0031] Combined with Figure 3 , Attachment Figure 5 and attached Figure 6 As shown, a pushing mechanism 7 is provided at the feed box 3, and the pushing mechanism 7 includes a transmission shaft 72 and a plurality of inclined pushing plates 71. One end of the main shaft 61 passes through a through hole on the crushing box 2 and is provided with a universal joint 8. The transmission shaft 72 is rotatably arranged at the bottom of the feed box 3 and the end thereof is connected to the universal joint 8. A cam 721 is provided on the transmission shaft 72 for pushing the pushing plate 71 to move, and adjacent cams 721 are in opposite directions.
[0032] The working principle of the pushing mechanism 7 is that the main shaft 61 is connected to the transmission shaft 72 through the universal joint 8. The rotation of the main shaft 61 will drive the transmission shaft 72 to rotate, thereby causing the multiple cams 721 to rotate. Since the adjacent cams are in opposite directions, when the cam 721 drives the pushing plate 71 to slide obliquely in the inclined groove 31, the adjacent pushing plates 71 move in opposite directions, thereby realizing an alternating pushing effect.
[0033] Combined with Figure 6 , Attachment Figure 7 and attached Figure 8 As shown, the bottom of the feed box 3 is obliquely provided with an inclined groove 31 that slides with the push plate 71, the bottom of the push plate 71 is provided with a transmission plate 711, the bottom of the feed box 3 is provided with an inclined groove 2 32 that slides with the transmission plate 711, the bottom of the transmission plate 711 is provided with an inclined platform 712 that cooperates with the cam 721, slide bars 713 are provided on both sides of the bottom of the push plate 71, and a groove platform 33 is provided at the bottom of the feed box 3. The slide bar 713 slides with the through hole on the inner side of the groove platform 33, and a spring 714 connected to the groove platform 33 is provided on the outer side of the slide bar 713, and guide grooves 715 are provided on both sides of the push plate 71. A soil discharge box 73 connected with the inclined groove 31 is provided below the feed box 3, and the bottom of the soil discharge box 73 is open.
[0034] Working principle of the push plate 71 and the soil discharge box 73: the cam 721 contacts the inclined platform 712 and pushes the push plate 71 to slide through the transmission plate 711. At this time, the spring 714 is compressed. After the cam 721 rotates, the elastic potential energy will push the slide bar 713 to reset the push plate 71. When the gap between multiple push plates 71 pushes the hay to move in the feed box 3, the push of the push plate 71 on the hay will cause the hay to vibrate, thereby shaking off the dust on the hay. The dust enters the soil discharge box 73 along the guide groove 715, realizing the soil removal operation of the hay.
[0035] Combined with Figure 1 and attached Figure 3 As shown, the output end of the motor 51 is provided with a screw rod 53 coaxially connected to the bevel gear 52, the screw rod 53 is arranged in the discharge pipe 4, the base 1 is provided with a plurality of hooks 11 near the discharge pipe 4, and a screen 22 is inserted into the groove at the connection between the bottom of the crushing box 2 and the discharge pipe 4.
[0036] Working principle of the discharge pipe 4: the forage bag is put on the pipe mouth of the discharge pipe 4 in advance, and the bag mouth is hung on the hook 11. When discharging, the crushed forage enters the discharge pipe 4 after being screened by the screen 22, and the spiral rod 53 driven by the motor 51 pushes the forage into the forage bag at the pipe mouth of the discharge pipe 4.
[0037] During the specific implementation of the utility model, the grass is fed into the feed box 3, and the grass is pushed into the crushing box 2 by the pushing mechanism 7, and the dust on the grass is shaken off. Driven by the driving mechanism 5, the two stirring discs 63 and the knife disc 66 of the crushing mechanism 6 rotate in opposite directions to realize the cutting, stirring and chopping functions, and then the grass is fed into the grass bag through the discharge pipe 4 by the spiral rod 53.
[0038] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
