Abstract
Description
Technical Field
[0001] This utility model relates to the field of forage processing, and in particular to a forage refining and grinding device for livestock. Background Technology
[0002] The fine grinding of livestock feed is a technology that uses mechanical means to process coarse and hard livestock feed into fine particles, powders or fragments. The core purpose is to improve the palatability of feed, increase the digestibility and absorption rate of animals, reduce feeding waste, and at the same time make it easier to mix with concentrates and additives to form total mixed rations.
[0003] For example, patent document CN223055724U discloses a livestock forage refining and grinding device, including a forage processing box. The top of the box is provided with a feed inlet. A driving component drives a grinding rod and a first auger to rotate. The rotating grinding rod grinds and crushes the forage. The crushed forage is screened once by a first filter plate and then enters the middle layer of the box. The first auger propels the forage by rotating. After passing through a second cylinder, the forage enters the lower layer of the box. Unqualified forage continues to be pushed into a lifting component. The lifting component lifts the forage to the upper layer and then it is ground a second time by the grinding rod. The second cylinder drives a pressure plate to squeeze the forage, squeezing out the water, which is discharged through a round hole at the bottom of the box. After squeezing, the first cylinder drives a baffle to descend. A discharge port is provided on the side of the baffle that contacts the box for discharging the material.
[0004] In existing technologies, most methods control the particle size of ground forage by screening it with sieves. However, in practical applications, the sieves are usually fixed, which leads to low screening efficiency and clogging. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] The present invention will be further described below with reference to the accompanying drawings:
[0028] like Figures 1-7 As shown, a livestock feed refining and grinding device includes a main body, which includes a support frame 101. Two symmetrically arranged slide rails 107 are bolted to the upper end of the support frame 101. An extension ear 108 is welded to one side of the support frame 101. A discharge mechanism is provided at the bottom of the support frame 101. A screen mechanism is provided inside the support frame 101, including a screen frame 301 slidably connected to the slide rails 107. An arc-shaped screen 302 is screwed to the screen frame 301. A fixing rod 304 extending outward from the support frame 101 is fixedly connected to one side of the screen frame 301, and the fixing rod 304 is slidably and sealingly connected to the support frame 101. A grinding rotor is provided on the support frame 101, including a rotating shaft 402 rotatably connected to the support frame 101 via bearings. A first bevel gear 405 is fixedly connected to one end of the rotating shaft 402. A crankshaft 406 is rotatably connected to the extension ear 108 via bearings, and a second bevel gear 405 is fixedly connected to the crankshaft 406. A bevel gear 407 meshes with a first bevel gear 405. Two connecting rods 408 are hinged to a crankshaft 406, with the other end of each connecting rod 408 hinged to a fixed rod 304. In use, the rotating shaft 402 rotates, driving the first bevel gear 405 to rotate. The first bevel gear 405 drives the second bevel gear 407 to rotate, which in turn drives the crankshaft 406 to rotate. The crankshaft 406 drives the connecting rods 408 to move, which in turn drives the fixed rod 304 to reciprocate. The fixed rod 304 then drives the screen frame 301 to reciprocate, which in turn drives the arc-shaped screen 302 to reciprocate. Thus, while the grinding rotor grinds and crushes the forage, the arc-shaped screen 302 vibrates back and forth. This improves the efficiency of forage screening and prevents forage from clogging the arc-shaped screen 302 through vibration. Furthermore, the slight relative displacement between the arc-shaped screen 302 and the grinding rotor further enhances the grinding efficiency of the forage.
[0029] The top of the support frame 101 is fixedly connected to the feed hopper 102, and the top of the screen frame 301 is fixedly connected to two symmetrically arranged baffles 303. The baffles 303 are slidably connected to the feed hopper 102 and extend into the feed hopper 102. The bottom of the support frame 101 is fixedly connected to the base 103. In use, the pre-treated grass enters the screen frame 301 from the feed hopper 102. The baffles 303 ensure that the grass in the screen frame 301 will not escape from the top when vibrating.
[0030] The discharge mechanism includes a feeding bin 204 fixedly connected to the base 103. An auger 201 is rotatably connected inside the feeding bin 204. The feeding bin 204 is located on the upper side of the bottom of the support frame 101 and is set with a bucket-shaped opening. A discharge pipe 205 is fixedly connected to the bottom of the feeding bin 204 on the side away from the support frame 101. In use, the ground and screened grass falls into the feeding bin 204. The auger 201 rotates and pushes the grass to move. The grass leaves the device from the discharge pipe 205.
[0031] A driven large bevel gear 202 is fixedly connected to one side of the auger 201, and a driving small bevel gear 203 is fixedly connected to the lower part of the crankshaft 406. The driving small bevel gear 203 meshes with the driven large bevel gear 202. When in use, the crankshaft 406 rotates, which drives the driving small bevel gear 203 to rotate. The driving small bevel gear 203 drives the driven large bevel gear 202 to rotate, and the driven large bevel gear 202 drives the auger 201 to rotate.
[0032] A motor 401 is fixedly connected to the support frame 101 on the side away from the extension ear 108. The output end of the motor 401 is fixedly connected to the rotating shaft 402. Several rotary blades 403 are fixedly connected to the rotating shaft 402. Several hammer-crushing blades 404 are hinged to the rotating shaft 402. Several hammer-crushing blades 404 are evenly distributed circumferentially at the same axial position on the rotating shaft 402. The rotary blades 403 and hammer-crushing blades 404 are staggered. When in use, the motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the rotary blades 403 and hammer-crushing blades 404 to rotate. During grinding, the rotary blades 403 chop the grass. For materials with smaller particles, the centrifugal impact force of the hammer-crushing blades 404 crushes the grass, thus achieving fine grinding of the grass.
[0033] The top of the base 103 is fixedly connected to two fixed shafts 104 arranged front and rear. A baffle fixedly connected to the base 103 is provided on the outside of the fixed shafts 104. An inspection door 105 is hinged on the fixed shafts 104. Several connecting components 106 are fixedly connected to the upper edge of the inspection door 105. The connecting components 106 can be the locking buckle or bolt buckle structure in the prior art. Several fixed seats corresponding to the connecting components 106 are fixedly connected to the side of the support frame 101. When the device needs to be repaired or the arc screen 302 needs to be replaced, the staff can release the lock of the connecting components 106, and then rotate the inspection door 105 to separate the inspection door 105 from the support frame 101 and push the inspection door 105 to one side to expose the space inside the support frame 101.
[0034] Working principle: Pre-treated forage enters the screen frame 301 from the feed hopper 102. The baffle plate 303 ensures that the forage in the screen frame 301 will not escape from the top during vibration. The motor 401 drives the rotating shaft 402 to rotate, which in turn drives the rotary cutter 403 and the hammer crusher 404 to rotate. During grinding, the rotary cutter 403 cuts the forage into smaller particles, and the centrifugal impact force of the hammer crusher 404 further crushes the forage, thus achieving fine grinding of the forage. At the same time, the rotating shaft 402 drives the first bevel gear 405 to rotate, which in turn drives the second bevel gear 407 to rotate, which in turn drives the crankshaft 406 to rotate. The drive link 408 moves, which in turn drives the fixed rod 304 to move back and forth. The fixed rod 304 drives the screen frame 301 to move back and forth, and the screen frame 301 drives the arc screen 302 to move back and forth. In this way, while the grinding rotor grinds and crushes the forage, the arc screen 302 can vibrate back and forth. This improves the efficiency of screening forage and prevents the forage from clogging the arc screen 302 through vibration. At the same time, the crankshaft 406 rotates, which drives the driving small bevel gear 203 to rotate. The driving small bevel gear 203 drives the driven large bevel gear 202 to rotate. The driven large bevel gear 202 drives the auger 201 to rotate. The rotation of the auger 201 pushes the forage to move, and the forage leaves the device from the discharge pipe 205.
[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
