[0002] When feeding livestock and poultry, it is usually necessary to chop the forage. Current forage chopping equipment generally includes a frame, a housing mounted on the frame, a drive mechanism located at the bottom of the housing, and a forage chopping mechanism located inside the housing. The drive mechanism drives the forage chopping mechanism to work, so as to chop the forage.

[0003] However, the inventors found in actual operation that the above-mentioned grass shredder has at least the following disadvantages: Since there is a certain gap between the grass shredder and the bottom surface of the shell, some of the shredded grass tends to accumulate in the gap during the grass shredding process, which makes it impossible for the grass shredder to cut the material. Usually, the equipment needs to be shut down and the grass in the gap needs to be cleaned manually before the grass shredder can continue to work. The operation is troublesome and the grass shredding efficiency is low. Utility Model Content

[0046] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0047] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use.

[0051] This application discloses a grass-chopping device for chopping grass and other materials. The grass-chopping device typically includes a frame, a housing mounted on the frame, a drive mechanism located at the bottom of the housing, and a grass-chopping mechanism housed within the housing. The inventors have discovered that existing grass-chopping devices have a gap between the grass-chopping mechanism and the bottom surface of the housing. During the grass-chopping process, some chopped grass tends to accumulate in this gap, causing the grass-chopping mechanism to malfunction. Typically, the equipment needs to be shut down, and the grass in the gap needs to be manually cleared before the grass-chopping mechanism can resume operation, which is cumbersome and inefficient. Therefore, this application provides a grass-chopping device that, by incorporating a pusher at the bottom of the cutting blade, automatically pushes the grass scraps that fall into the gap between the bottom wall of the housing and the cutting blade towards the discharge port when the drive mechanism rotates to perform the cutting operation. This prevents the scraps from accumulating at the bottom of the cutting blade, thus ensuring the normal operation of the grass-chopping mechanism. Therefore, the grass shredder of this invention can automatically clean the debris at the bottom of the cutting blade during operation, thereby ensuring the normal operation of the cutting blade. It does not require manual operation, saving time and effort and increasing work efficiency.

[0052] Please see Figures 1 to 7 The diagram shown is a structural schematic of a grass-chopping device according to one embodiment. The grass-chopping device in this embodiment includes a frame 10, a housing 20, a grass-chopping mechanism 30, and a drive mechanism 40.

[0053] The frame 10 mainly serves a supporting function, supporting the housing 20 and the drive mechanism 40. The frame 10 can be welded from profiles such as channel steel and angle steel. The top of the frame 10 is provided with a support plate, and the support plate has a first discharge port 11.

[0054] The housing 20 is mounted on the frame 10 and can be detachably connected to the frame 10 via a snap-fit ​​structure. The housing 20 has an internal cavity, with a feed inlet 21 at the top and a second discharge outlet 22 at the bottom that communicates with the first discharge outlet 11. The cavity is used to accommodate the grass-chopping mechanism 30 and the material fed in through the feed inlet 21. The specific shape of the housing 20 is not limited here; for example, it can be circular, polygonal, etc. This embodiment describes the housing 20 as circular.

[0055] The grass-chopping mechanism 30 is disposed inside the housing 20 and is used to cut the material placed inside the housing 20. The grass-chopping mechanism 30 includes a cutter shaft 31 and a cutting blade 32 mounted on the cutter shaft 31. The bottom surface of the cutting blade 32 facing the second discharge port 22 is provided with a pusher 33, which is used to push the grass fragments that fall into the gap between the bottom wall of the housing 20 and the cutting blade 32 toward the second discharge port 22.

[0056] The drive mechanism 40 is mounted on the frame 10 and is connected to the cutter shaft 31 of the grass shredding mechanism 30. It is used to drive the grass shredding mechanism 30 to rotate for cutting operations. When the grass shredding mechanism 30 rotates, the pusher 33 at its bottom also rotates, thereby automatically pushing the grass scraps that fall into the gap between the bottom wall of the housing 20 and the cutting blade 32 to the second discharge port 22 for discharge, avoiding the accumulation of scraps at the bottom of the cutting blade 32, thus ensuring the normal operation of the grass shredding mechanism 30.

[0057] Please see Figure 7 As shown, in some embodiments of this application, multiple cutting blades 32 can be provided. These multiple cutting blades 32 are spaced apart along the axial direction of the cutter shaft 31, and are staggered along the circumferential direction of the cutter shaft 31. The pusher 33 is disposed on the bottommost cutting blade 32. By providing multiple cutting blades 32, cutting efficiency and cutting quality can be improved.

[0058] It should be noted that "multiple" refers to a quantity of 2 or more, such as 2, 3, 4, etc.

[0059] The cutting blade 32 may be arc-shaped, with a cutting edge formed on its inner arc surface, and a connecting part at one end. The connecting part can be fixedly connected to the blade shaft 31 by welding or bolts. Of course, in some embodiments of this application, the cutting blade 32 is S-shaped, with its middle part connected to the blade shaft 31 and cutting edges formed on its two diagonal edges.

[0060] Among them, the pusher 33 can be a push plate fixed on the bottom surface of the cutting blade 32. The push plate can be arc-shaped or straight.

[0061] Please see Figure 6 In some embodiments of this application, the drive mechanism 40 may include a drive motor 41, a pulley 42, and a belt 43. The drive motor 41 can be fixed inside the frame 10 by bolts or other fasteners. The pulley 42 is located at the bottom end of the cutter shaft 31 extending into the frame 10. The belt 43 connects the output shaft of the drive motor 41 and the pulley 42. By installing the drive motor 41 inside the frame 10, this application not only improves the overall aesthetics but also reduces the size of the equipment, facilitating packaging and transportation. Secondly, since the drive motor 41 and the cutter shaft 31 are connected by the pulley 42 and the belt 43, the belt 43 can act as a buffer when the cutting blade 32 gets stuck, reducing damage to the drive motor 41 and extending its service life. In addition, by setting the belt 43, the drive motor 41 and the cutter shaft 31 can be staggered, preventing the juice from the crushed material inside the housing 20 from flowing into the drive motor 41 along the cutter shaft 31 and affecting its operation.

[0062] Furthermore, in some embodiments of this application, the grass-chopping device may further include a baffle plate 50 disposed between the frame 10 and the housing 20, the baffle plate 50 having a connecting hole connecting the first discharge port 11 and the second discharge port 22. Specifically, the baffle plate 50 may be a grid plate, which can filter out large pieces of unchopped material inside the housing 20 to ensure that the discharged material is completely chopped.

[0063] Furthermore, the baffle plate 50 can move back and forth relative to the frame 10. When the shredded material cannot be discharged in time and gets stuck on the baffle plate 50, the baffle plate 50 can be pulled out to fully open the discharge port so that the material can be discharged quickly.

[0064] The grass shredder also includes a lifting component 60, which is positioned between the frame 10 and the housing 20 to create a gap between the top surface of the frame 10 and the bottom surface of the housing 20, allowing the baffle plate 50 to move. The lifting component 60 can be a rivet nut fixed to the top of the frame 10. Multiple lifting components 60 can be provided, evenly distributed on the frame 10, thereby ensuring the stability of the housing 20.

[0065] It should be noted that the lifting distance of the lifting component 60 can be set according to actual needs, as long as the baffle plate 50 can slide smoothly.

[0066] Furthermore, the frame 10 is provided with a guide groove for guiding the movement of the baffle plate 50. The guide groove can be a groove formed on the top surface of the frame 10, and the bottom surface of the baffle plate 50 is provided with a slider that is slidably connected in the groove. By providing the guide groove, the movement direction of the baffle plate 50 can be guided, preventing problems such as deflection of the baffle plate 50 during movement.

[0067] Furthermore, in some embodiments of this application, the grass-chopping device may further include a discharge hopper 70 disposed on the frame 10. One end of the discharge hopper 70 is connected to the first discharge port 11, and the other end extends outward from the frame 10. The discharge hopper 70 may include a first baffle and a second baffle, both of which may be U-shaped. One end of the first baffle is connected to the inner wall of the frame 10 by a rivet nut and is connected to the first discharge port 11. One end of the second baffle is connected to the end of the first baffle away from the first discharge port 11, and the other end is inclined downward and outward from the frame 10. By providing the discharge hopper 70, the grass-chopping material discharged from the first discharge port 11 can be guided to flow into the outside of the frame 10, and the grass-chopping material can also be shielded to prevent it from splashing everywhere.

[0068] Furthermore, in some embodiments of this application, the grass-chopping device may also include a feed hopper 80 disposed at the first discharge port 11, the feed hopper 80 being shaped like a funnel, wider at the top and narrower at the bottom. By providing the feed hopper 80, the user can easily observe the grass-chopping situation inside the housing 20, while also preventing the grass fragments inside the housing 20 from splashing during operation.

[0070] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner.
