Description

Technical Field

[0001] This utility model belongs to the technical field of chaff cutters, specifically relating to a livestock chaff cutter. Background Technology

[0002] In the process of animal husbandry, different feeds need to be fed. During feeding, grass needs to be cut into different lengths to accommodate different livestock. The grass cutter is a key piece of equipment for processing grass.

[0003] Some chaff cutters use a traditional narrow-mouth feeding design, which requires manual feeding to process chaff. This not only increases the intensity of manual labor, but also poses a safety hazard of accidental injury from high-speed rotating parts, especially when the hands are close to the feeding inlet during large-scale chaff processing.

[0004] Some chaff cutters use conveyor belts to transport fodder instead of manual pushing, which reduces close contact between workers and equipment. However, when dealing with large clumps of loose fodder, workers need to manually break them down and compress them into smaller volumes before laying them flat on the conveyor belt. This is to prevent the fodder from getting stuck in the channel due to its large size or loose structure. The extra breaking, compressing, and laying operations prolong the fodder processing time and reduce the efficiency of fodder processing. Utility Model Content

[0005] The purpose of this invention is to provide a livestock hay chopper that allows large, tangled, and loose hay to be directly fed without prior splitting and compression. It can break up clumps of hay to avoid blockages, deliver hay stably and evenly, and improve hay processing efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1-4 As shown, a livestock chaff cutter includes a U-shaped support frame 1 and a chaff cutter housing 4 fixed to the top of the U-shaped support frame 1, and a drive motor 2 installed inside the U-shaped support frame 1. The output end of the drive motor 2 is fixed with a first double-pulley 3. A cutter disc assembly is installed inside the chaff cutter housing 4. The two ends of the chaff cutter housing 4 are respectively provided with a feed inlet and a discharge outlet. The cutter disc assembly includes a throwing blade group, a chopping blade group, and a transmission rod 23 that drives the throwing blade group and the chopping blade group. The transmission rod 23 passes through the inside of the chaff cutter housing 4 and is rotatably connected to the chaff cutter housing 4. A first pulley 5, which is connected to the first double-pulley 3 via a belt, is fixed to the outside of the transmission rod 23 and located on the chaff cutter housing 4. A feeding assembly is provided at the feed inlet of the chaff cutter housing 4.

[0021] The aforementioned U-shaped support frame 1, drive motor 2, first double-pulley 3, chaff cutter housing 4, throwing blade assembly, shredding blade assembly, and transmission rod 23 are all existing mature technologies. The drive motor 2 operates, and through the first double-pulley 3 and the first pulley 5, it causes the transmission rod 23 to rotate. The transmission rod 23 drives the throwing blade assembly and the shredding blade assembly to operate, shredding and throwing the material entering the chaff cutter housing 4. In this embodiment, they will not be described in detail. The core solution of this technical solution lies in the specific structure of the feeding assembly.

[0022] The feeding assembly includes a feed hopper 6 installed at an angle on the chaff cutter housing 4. The feed hopper 6 adopts a flat-bottomed conical design, with the feed end and discharge end at the two ends of the feed hopper 6, respectively. When the feed hopper 6 is installed on the chaff cutter housing 4, the feed end of the feed hopper 6 is higher than the discharge end.

[0023] See attached document Figure 1 , 3 and attached Figure 4 The feed hopper 6 is designed with a large opening at the feed end to facilitate the collection of larger materials. The feed end of the feed hopper 6 gradually narrows towards the discharge end, and the discharge end is adapted to the feed inlet of the chaff cutter housing 4. After the feed hopper 6 is installed, the discharge end is located inside the feed inlet of the chaff cutter housing 4 to ensure the directional introduction of materials.

[0024] See attached document Figure 1 and attached Figure 4 To facilitate the disassembly and installation of the feed hopper 6, the feed hopper 6 is installed on the chaff cutter housing 4 via an installation assembly. The installation assembly includes two rectangular limiting plates 17 fixed on both sides of the chaff cutter housing 4. Rectangular support plates 16 that can be inserted into the rectangular limiting plates 17 are fixed on both sides of the feed hopper 6. The rectangular limiting plates 17 and the rectangular support plates 16 are interference-fitted. The rectangular limiting plates 17 limit the rectangular support plates 16, so that the rectangular support plates 16 can only move along their length direction inside the rectangular limiting plates 17.

[0025] See attached document Figure 4 The mounting assembly also includes two T-shaped plates 18. The lower vertical portions of the two T-shaped plates 18 are inserted into the rectangular limiting plate 17 and the rectangular support plate 16 on the same side, respectively. The top of the T-shaped plates 18 is located above the rectangular limiting plate 17. When the T-shaped plates 18 are inserted into the rectangular support plate 16 and the rectangular limiting plate 17, the rectangular support plate 16 can be limited again, restricting the rectangular support plate 16 from moving along the length direction of the rectangular limiting plate 17, thereby achieving the positioning of the rectangular support plate 16 and the feed hopper 6.

[0026] To reduce the risk of the T-shaped plate 18 falling out of the rectangular limiting plate 17 and the rectangular support plate 16 due to unintentional upward movement, a first magnetic block 19 is installed on the top of the rectangular limiting plate 17, and a second magnetic block 20 adapted to the first magnetic block 19 is installed on the lower part of the upper horizontal portion of the T-shaped plate 18. When the T-shaped plate 18 is inserted into the rectangular limiting plate 17 and the rectangular support plate 16, the first magnetic block 19 and the second magnetic block 20 will generate magnetic attraction. The cooperation of the first magnetic block 19 and the second magnetic block 20 can reduce the possibility of the T-shaped plate 18 falling out unintentionally.

[0027] In use: Lift the feed hopper 6, insert the rectangular support plate 16 on the feed hopper 6 into the inside of the rectangular limiting plate 17, and then insert the T-shaped plate 18 into the inside of the rectangular limiting plate 17 and the rectangular support plate 16 to complete the installation of the feed hopper 6. When disassembling the feed hopper 6, simply pull out the T-shaped plate 18.

[0028] See attached document Figure 1 - Appendix Figure 4 A first round rod 7 is provided at the bottom of the feed hopper 6 and near the feed end, and a second round rod 8 is provided at the bottom of the feed hopper 6 and near the discharge end. The two ends of the first round rod 7 and the second round rod 8 are respectively rotatably connected to the mounting block 22, and the mounting block 22 is fixed to the bottom of the feed hopper 6.

[0029] Both the second round rod 8 and the first round rod 7 have multiple rectangular positioning plates 13 inserted inside.

[0030] Wherein: the rectangular positioning plates 13 on the first round rod 7 are arranged in a ring array inside along its axis and pass through one end of the first round rod 7;

[0031] The rectangular positioning plates 13 on the second round rod 8 are arranged in a ring array inside along the axis of the second round rod 8 and pass through one end of the second round rod 8;

[0032] Multiple material-pulling knife sets are also installed on the first round rod 7, and the multiple material-pulling knife sets are evenly arranged along the length direction of the rectangular positioning plate 13 on the first round rod 7.

[0033] Each set of material feeding blades includes a number of first blades 11 equal to the number of rectangular positioning plates 13, and multiple rectangular positioning plates 13 are respectively inserted into the first blades 11 of each set of material feeding blades. At the same time, a first slot adapted to the bottom of the first blade 11 is opened on the first round rod 7, and the bottom of the first blade 11 is embedded in the first slot.

[0034] Multiple material conveying knife sets are installed on the inner side of the second round rod 8, and the multiple material conveying knife sets are evenly arranged along the length direction of the rectangular positioning plate 13 on the second round rod 8.

[0035] Each set of feed knife groups includes a second blade 12 in the same number as the rectangular positioning plates 13, and multiple rectangular positioning plates 13 are respectively inserted into the second blade 12 of each set of feed knife groups. In addition, a second slot adapted to the bottom of the second blade 12 is provided on the second round rod 8, and the bottom of the second blade 12 is embedded in the second slot.

[0036] Both the first round rod 7 and the second round rod 8 have a plug 14 fixed to one end by a bolt 15. When the two plugs 14 are installed on the first round rod 7 and the second round rod 8 respectively, the plugs 14 can abut against one end of the rectangular positioning plate 13. Through the cooperation of the plugs 14 and the bolts 15, the rectangular positioning plate 13 inside the first round rod 7 and the second round rod 8 can be stably fixed to prevent loosening.

[0037] By tightening the two bolts 15, the two plugs 14 are separated from the first round rod 7 and the second round rod 8, so that the rectangular positioning plate 13 inside the first round rod 7 and the second round rod 8 can be removed, so that the rectangular positioning plate 13 releases the restriction on the first blade 11 and the second blade 12, thus providing convenience when the first blade 11 and the second blade 12 need to be replaced after long-term use.

[0038] See attached document Figure 1 and attached Figure 4 The bottom of the feed hopper 6 is provided with a first cutting groove adapted to the first blade 11 and a second cutting groove adapted to the second blade 12;

[0039] When the feeding knife group and the conveying knife group are working, multiple first blades 11 and multiple second blades 12 can be screwed into the feed hopper 6 through the corresponding knife slots, and the length of the second blade 12 is set to be longer than that of the first blade 11.

[0040] One end of the second round rod 8 is fixed with a second double pulley 9, which is connected to the first double pulley 3 via a belt. One end of the first round rod 7 is fixed with a second pulley 10, which is connected to the second double pulley 9 via a belt.

[0041] When using:

[0042] When the drive motor 2 operates and causes the first double pulley 3 to rotate, the first double pulley 3 drives the second double pulley 9 and the second pulley 10 to rotate through belt transmission, thereby driving the first round rod 7 and the second round rod 8 to rotate, causing the first blade 11 of the feeding knife group and the second blade 12 of the conveying knife group to rotate.

[0043] The enlarged opening design at the feed end of the feed hopper 6 allows large clumps, tangled, and fluffy hay to be easily fed into the feed hopper 6. Workers do not need to pre-separate or compress the hay; they can simply feed the clumps and tangled hay directly into the feed end of the feed hopper 6, greatly improving the ease of operation. When the first blade 11 rotates, it penetrates deep into the hay to effectively disperse and hook up clumps and tangled hay, preventing accumulation and blockage. After the hay is evenly dispersed, it enters the rotating area of ​​the second blade 12.

[0044] The second blade 12 can continuously and stably convey the material into the chaff cutter housing 4. The feeding amount is relatively uniform. After entering the chaff cutter housing 4, the chopping blade group performs chopping, and then the throwing blade group throws the chopped grass outward to complete the entire processing.

[0045] Meanwhile, the first blade 11 and the second blade 12 can also pre-cut the grass during rotation, reducing the load on the subsequent shredding blade assembly;

[0046] By adapting the first cut seam to the first blade 11 and the second cut seam to the second blade 12, the entanglement of grass on the outside of the first blade 11 and the second blade 12 can be reduced respectively.

[0047] The design of installing the first round rod 7 and the second round rod 8 at the bottom of the feed hopper 6 reduces the probability of grass getting tangled on the outside of the first round rod 7 and the second round rod 8, and further improves the smoothness of equipment operation;

[0048] A storage tank 21 is provided at the bottom of the feed hopper 6 and below the first round rod 7 and the second round rod 8. The storage tank 21 can be fixed to the ground or to the U-shaped support frame 1.

[0049] The straw that falls out from the first and second cuts can fall directly into the storage bin 21 for storage and be taken out from the feeding port, avoiding the accumulation of scattered straw at the bottom of the equipment and causing a cleaning burden. At the same time, the storage bin 21 forms a physical shield for the first round rod 7 and the second round rod 8, the first blade 11 and the second blade 12, preventing personnel from contacting the first blade 11 and the second blade 12 when the first round rod 7 and the second round rod 8 are rotating at high speed, further improving the safety of the equipment during operation.

[0050] In summary, this utility model allows large, tangled, and fluffy hay to be directly fed in without prior splitting and compression through the feeding component. In addition, the cooperation of the first blade 11 and the second blade 12 can break up clumps of hay to avoid blockage, ensure stable conveying and uniform feeding, improve hay processing efficiency, and enhance the smoothness of equipment operation.

[0051] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
