Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-6 , the present invention provides a technical solution: In order to improve the cutting and crushing performance of the device, a livestock grass crusher is proposed, including a machine body 1, a conveyor belt 2, and a cutting mechanism 3. The conveyor belt 2 is arranged below the machine body 1, and a penetration notch 201 is arranged on the conveyor belt 2. Grass is transported to the bottom of the cutting mechanism 3 through the conveyor belt 2. The cutting mechanism 3 is arranged in the machine body 1. The cutting knife 312 of the cutting mechanism 3 is movably installed in the machine body 1. A notch corresponding to the cutting knife 312 is arranged on the lower surface of the machine body 1. The grass on the conveyor belt 2 is cut by the cutting knife 312. A crushing mechanism 4 is arranged on one side of the cutting mechanism 3. The time required for each penetration gap 201 on the conveyor belt 2 to move successively under the cutting knife 312 is the same as the total movement time required for the reciprocating motion of the cutting knife 312, ensuring that the cutting knife 312 passes through the penetration gap 201 during cutting.

[0017] The cutting mechanism 3 includes: a motor 301, a rotating wheel 303, and a cutting knife 312. The motor 301 is fixedly arranged in the machine body 1. The output shaft of the motor 301 is fixedly connected to one end of the first connecting rod 302. The other end of the first connecting rod 302 is fixedly connected to the rotating wheel 303. The non-center of the surface of the rotating wheel 303 is hinged to one end of the first pushing rod 304. The other end of the first pushing rod 304 is hinged to one end of the pushing plate 305. One side of the pushing plate 305 is fixedly connected to the first sliding block 306. The first sliding block 306 is slidably mounted. In the first slide rail 307, the first slide rail 307 is fixedly arranged in the machine body 1, the other end of the push plate 305 is fixedly connected to one end of the "U"-shaped plate 308, the other end of the "U"-shaped plate 308 is fixedly connected to the mounting plate 309, and the second sliders 310 are fixedly arranged on both sides of the mounting plate 309. The second sliders 310 are slidably installed in the second slide rail 311, and the second slide rail 311 is fixedly arranged in the machine body 1. The end of the mounting plate 309 away from the "U"-shaped plate 308 is detachably connected to the cutting knife 312 through screws; The motor 301 and the telescopic rod 323 adopt the existing technology.

[0018] The motor 301 provides energy for the first connecting rod 302 to rotate. The rotation of the first connecting rod 302 drives the rotating wheel 303 to rotate. The rotation of the rotating wheel 303 will drive one end of the first push rod 304 to move. The overall length of the first push rod 304 will not change, so the other end of the first push rod 304 will change in position. The movement of the first push rod 304 will pull or push the push plate 305 to move. The push plate 305 drives the first slider 306 to slide in the first slide rail 307. Under the restriction of the first slide rail 307, the push plate 305 moves up and down in a straight line. This structure is similar to the existing crank slider mechanism. When moving, the push plate 305 will drive the "U"-shaped plate 308 to move, and the cutting knife 312 will move in a straight line to cut the grass.

[0019] The middle part of the first connecting rod 302 is fixedly connected to two first pulleys 313, each of which is sleeved with one end of a first belt 314, and the other end of the first belt 314 is sleeved on the second pulley 315. The second pulley 315 is rotatably arranged in the body 1, and one side of the second pulley 315 is fixedly connected to one end of a toggle rod 316, and a toggle tooth 317 is arranged on the surface of the toggle rod 316. The toggle rod 316 is meshed and connected with two eccentric wheels 318 through the toggle tooth 317. The side of the eccentric wheel 318 is provided with teeth. The eccentric wheel 318 is hinged to one end of the second connecting rod 319 at the center. The other end of the second connecting rod 319 passes through the fixed plate 320 and is fixedly connected to the upper surface of the pressing plate 322.

The upper surface of the pressing plate 322 is fixedly connected to one end of the first spring 321. The other end of the first spring 321 is fixedly connected to the lower surface of the fixed plate 320. The first spring 321 is sleeved on the surface of the telescopic rod 323. One end of the telescopic rod 323 is fixedly connected to the fixed plate 320, and the other end is fixedly connected to the upper surface of the pressing plate 322. The pressing plate 322 is in contact with the surface of the forage.

[0020] When the first connecting rod 302 rotates, it will drive the two first pulleys 313 to rotate at the same time. The two first pulleys 313 are of the same size. The first pulley 313 rotates through the first belt 314 to drive the second pulley 315 to rotate. The rotation of the second pulley 315 drives the toggle rod 316 to rotate. The toggle rod 316 is meshed and connected with the eccentric wheel 318. Therefore, the rotation of the toggle rod 316 drives the eccentric wheel 318 to rotate. When the center of the eccentric wheel 318 gradually rotates away from When the lever 316 is moved, the first spring 321 is extended, the telescopic rod 323 is extended, the second connecting rod 319 slides on the fixing plate 320, and drives the pressing plate 322 to move toward the direction of the grass material, and gradually extends to the outside of the machine body 1. The pressing plate 322 presses the grass material tightly, thereby facilitating the cutting knife 312 to cut the grass material, preventing the grass material from being squeezed into a "V" shape when the cutting knife 312 is cutting, and not easy to enter under the subsequent roller 405, and fixing the position of the grass material, facilitating the cutting of the cutting knife 312; When the center of the eccentric wheel 318 gradually rotates to a position close to the toggle rod 316, due to the reset of the first spring 321, the telescopic rod 323 is shortened, and the first spring 321 pulls the pressure plate 322 to move toward the fixed plate 320. The pressure plate 322 no longer presses the grass, and under the reset force of the first spring 321, the eccentric wheel 318 and the toggle rod 316 are ensured to continue to engage and not disengage.

[0021] The total time required for the reciprocating motion of the pressing plate 322 is the same as the total time required for the reciprocating motion of the cutting blade 312 , ensuring that the reciprocating directions of the pressing plate 322 and the cutting blade 312 remain the same.

[0022] In order to improve the crushing capacity of the device, a livestock forage crusher is proposed, the crushing mechanism 4 includes: a third connecting rod 401, a roller 405, the toggle rod 316 is fixedly connected to the first contact disc 5 at the end away from the second pulley 315, the first contact disc 5 is meshed with the second contact disc 501, the surfaces of the first contact disc 5 and the second contact disc 501 are provided with teeth corresponding to each other, the second contact disc 501 is slidably installed on the third connecting rod 401, a spline shaft is provided at one end of the third connecting rod 401, the second contact disc 501 is slidably installed on the spline shaft, one end of the second contact disc 501 is rotatably installed on one side of the second contact disc 501, the other end of the fourth connecting rod 502 is rotatably connected to the side of another second contact disc 501, a fixing frame 503 is fixedly arranged in the middle of the fourth connecting rod 502, a threaded rod 504 is fixedly arranged on the fixing frame 503, the threaded rod 504 extends out of the machine body 1, and a screw 505 is threadedly connected to the surface of the threaded rod 504.

[0023] The other end of the third connecting rod 401 is fixedly connected to the third pulley 402, and one end of the second belt 403 is sleeved on the third pulley 402. The other end of the second belt 403 is sleeved on the fourth pulley 404. One side of the fourth pulley 404 is rotatably installed in the machine body 1, and the other side of the fourth pulley 404 is fixedly connected to the roller 405. The other end of the roller 405 is rotatably installed in the machine body 1, and the surface of the roller 405 is in contact with the surface of the forage.

[0024] As the toggle rod 316 rotates, the first contact disk 5 will rotate. When the first contact disk 5 is meshed and connected with the second contact disk 501, the first contact disk 5 will drive the second contact disk 501 to rotate. The rotation of the second contact disk 501 drives the third connecting rod 401 to rotate, and the third pulley 402 rotates. Through the transmission of the second belt 403, the fourth pulley 404 rotates. The fourth pulley 404 drives the roller 405 to rotate, and the roller 405 crushes the grass below it.

[0025] Loosen the screw 505, pull the threaded rod 504 out of the body 1, tighten the screw 505, the first contact plate 5 is disconnected from the second contact plate 501, the second contact plate 501 loses kinetic energy input, the second contact plate 501 does not rotate, the third connecting rod 401 no longer rotates, and the roller 405 stops rotating.

[0026] Working principle of the present invention: The grass is placed parallel to the conveyor belt 2, and the conveyor belt 2 is used to transport the grass to the first roller 405 for preliminary crushing, so as to facilitate subsequent cutting and crushing.

[0027] Then the conveyor belt 2 transports the fodder to the bottom of the cutting mechanism 3, and the motor 301 is turned on. The motor 301 provides energy for the first connecting rod 302 to rotate. The rotation of the first connecting rod 302 drives the rotating wheel 303 to rotate. The rotation of the rotating wheel 303 drives one end of the first push rod 304 to move. The movement of the first push rod 304 pulls or pushes the push plate 305 to move. The push plate 305 drives the first slider 306 to slide in the first slide rail 307. The push plate 305 moves up and down in a straight line. When moving, the push plate 305 drives the "U"-shaped plate 308 to move, and the cutting knife 312 moves in a straight line to cut the fodder.

[0028] When the cutting knife 312 descends to cut the grass, the first connecting rod 302 rotates to drive the two first pulleys 313 to rotate at the same time, the second pulley 315 rotates, the toggle rod 316 rotates, and the eccentric wheel 318 rotates. When the center of the eccentric wheel 318 gradually rotates to a position away from the toggle rod 316, the first spring 321 extends, the telescopic rod 323 extends, and the second connecting rod 319 slides on the fixed plate 320, and drives the pressing plate 322 to move toward the direction of the grass and gradually extends to the outside of the machine body 1. The pressing plate 322 presses the grass, thereby facilitating the cutting knife 312 to cut the grass, preventing the grass from being squeezed into a "V" shape when the cutting knife 312 cuts, and it is not easy to enter under the subsequent roller 405, and fixing the position of the grass, facilitating the cutting of the cutting knife 312; After the cutting knife 312 completes cutting the grass, the cutting knife 312 rises, and the center of the eccentric wheel 318 gradually rotates to a position close to the toggle rod 316. Due to the reset of the first spring 321, the telescopic rod 323 is shortened, and the first spring 321 pulls the pressure plate 322 to move toward the fixed plate 320. The pressure plate 322 no longer presses the grass, and under the reset force of the first spring 321, it is ensured that the eccentric wheel 318 and the toggle rod 316 continue to engage and do not disengage.

[0029] The conveyor belt 2 passes the hay under the second roller 405, and the second roller 405 crushes the hay again to improve the degree of crushing of the hay.

[0030] When only the grass needs to be cut into segments and no crushing is required, the screw 505 is loosened, and the threaded rod 504 is pulled out of the body 1, and the screw 505 is tightened, the first contact plate 5 is disconnected from the second contact plate 501, the second contact plate 501 loses kinetic energy input, the second contact plate 501 does not rotate, the third connecting rod 401 no longer rotates, and the roller 405 stops rotating.
