A second grinding disc is rotatably installed inside the barrel body, and a first grinding disc is positioned on top of the second grinding disc. A feed guide pipe extends through and is fixedly installed on one side of the bottom of the cutting chamber. A sleeve is fixedly installed through and around the center of the top of the first grinding disc, and the sleeve is fitted onto the outer wall of the lower end of the feed guide pipe.

This two-stage processing effectively solves the defects of coarse, hard lumps or incomplete crushing in single-stage processing, improving feed palatability and animal digestibility.

Description

Technical Field

[0001] This utility model relates to the field of forage crushing technology, and in particular to a forage crushing and cutting machine. Background Technology

[0002] In the livestock feed processing sector, forage pulverization is a crucial step in improving feed palatability, digestibility, and storage convenience. Existing forage processing equipment has significant technical limitations in its processing flow, mainly in the following aspects:

[0003] Traditional equipment often uses a single cutting or crushing method (such as simply hitting with hammers or rolling with rollers), resulting in a coarse processing effect for forage. For example, simply cutting forage fibers is not sufficiently broken down, resulting in uneven lengths and a hard texture, leading to low digestibility after animals consume it. Equipment that simply rolls forage is difficult to process longer or coarser forage, and is prone to tangling and clogging. Furthermore, the rolled material tends to clump together, resulting in poor uniformity and poor palatability of the forage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a forage crushing and cutting machine, which solves the problems that simple cutting or crushing equipment is prone to entanglement and blockage, and the crushed material is prone to clumping and poor uniformity, resulting in poor palatability of the forage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A forage shredder and cutter includes a barrel body, a cutting chamber fixedly installed on the top of the barrel body, a second grinding disc rotatably installed inside the barrel body, and a first grinding disc disposed on the top of the second grinding disc;

[0007] A material guide pipe is provided, which is installed through and fixedly installed on one side of the bottom of the cutting chamber. A sleeve is installed through and fixedly installed at the center of the top of the first grinding disc, and the sleeve is fitted on the outer wall of the lower end of the material guide pipe.

[0011] The second drive assembly is mounted on the barrel and is used to drive the second grinding disc to rotate.

[0012] An adjustment component is mounted on the barrel and is used to adjust the distance between the first grinding disc and the second grinding disc.

[0013] Preferably, the feeding assembly includes:

[0014] A first conveyor belt is fixedly installed on the bottom of the cutting chamber, and a second conveyor belt is fixedly installed on the top of the cutting chamber. The distance between the second conveyor belt and the first conveyor belt is gradually changing. A material guide channel is provided on one side of the small distance end of the second conveyor belt and the first conveyor belt, and the material guide channel is fixedly installed on the inner wall of the cutting chamber.

[0015] Preferably, the cutting assembly includes:

[0016] The main shaft is rotatably mounted on the inner wall of one end of the cutting chamber. The main shaft is located on the upper side of the material guide pipe. Multiple saw blades are fixedly mounted on the outer wall of the main shaft, with one side of each saw blade close to the opening of the material guide channel.

[0017] Preferably, the first driving component includes:

[0018] The first motor is fixedly installed on the top of the cutting chamber. The output end of the first motor and the shaft end of the main shaft are both fixedly installed with first synchronous pulleys. A first synchronous belt is sleeved between the outer walls of the two first synchronous pulleys.

[0019] Preferably, the second driving component includes:

[0020] The second motor is fixedly installed on the bottom outer wall of the barrel. The output end of the second motor and the shaft end of the bottom of the second grinding disc are both fixedly installed with second synchronous pulleys.

The second synchronous belt and the second synchronous pulley are both inside the isolation shell.

[0021] Preferably, the adjustment component includes:

[0022] Four adjusting brackets are fixedly installed on the four sides of the top of the first grinding disc. The other end of each of the four adjusting brackets passes through and is slidably connected to the barrel body. Two bearing seats are fixedly installed on the outer walls of the four sides of the barrel body. A threaded rod is rotatably installed between each two adjacent bearing seats. The four threaded rods pass through and are threadedly connected to one end of each of the four adjusting brackets.

[0023] Preferably, the first and second grinding discs are separated from the inner wall of the barrel, and the bottom of the barrel is funnel-shaped.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0076] Second conveyor belt 21: a chain plate type conveyor belt matched with the first conveyor belt 17, the installation height of which can be finely adjusted to form a gradual spacing (inlet spacing 100-150mm, outlet spacing 30-50mm), driven by the same geared motor (synchronous reverse rotation is achieved through a gearbox).

[0077] Working principle:

[0078] The first step involves inserting hay into the large openings of the first conveyor belt 17 and the second conveyor belt 21. The hay needs to be inserted longitudinally and moved towards the cutting assembly under the conveying of the first conveyor belt 17 and the second conveyor belt 21. Since the interval between the first conveyor belt 17 and the second conveyor belt 21 is gradual, the hay will be compacted during the conveying process to the cutting assembly and then pass through the guide channel 18 with the gradual opening.

[0079] The second step involves starting the first motor 3, which, through the transmission of the first synchronous belt 5 and the two first synchronous pulleys 4, causes the main shaft 19 to start rotating, driving the saw blade 20 to rotate as well. Multiple blades on both sides of the saw blade 20 will cut the hay at high speed. The cut hay will fall into the feed pipe 11, then slide down along the inclined inner wall of the feed pipe 11, and enter the sleeve 12 from the lower port. Finally, it will enter the gap between the first grinding disc 13 and the second grinding disc 14 through the other port of the sleeve 12.

[0080] The third step involves starting the second motor 10, which, through the transmission of the two second synchronous pulleys 9 and the second synchronous belt 16, causes the second grinding disc 14 to start rotating. The relative rotation of the first grinding disc 13 and the second grinding disc 14, combined with the crushing of the forage by the first grinding disc 13 and the second grinding disc 14, crushes the forage. Then, under the continuous rotation of the second grinding disc 14 and the action of centrifugal force, the crushed forage is discharged from the edge of the second grinding disc 14 and falls into the barrel 1, and finally discharged from the lower port of the barrel 1.

[0081] Fourth, the isolation shell 15 can protect the second synchronous pulley 9 and the second synchronous belt 16 to prevent the hay from getting tangled in them. By rotating multiple threaded rods 7 in the same direction, the relative position of the adjusting bracket 6 and the threaded rods 7 is changed, thereby changing the height of the first grinding disc 13. This allows the degree of hay crushing to be adjusted by changing the gap between the first grinding disc 13 and the second grinding disc 14.

[0082] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
