Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a protective cover structure for a shredder. Background Technology

[0002] A shredder is a mechanical device used to process hard materials such as crop stalks, straw, and branches into soft, fibrous materials. It uses high-speed rotating blades or hammers to rub and chop the materials, breaking down the hard nodes on the surface and making them soft and lump-free, easier for livestock to eat and digest, while also improving material utilization. Shredders are widely used in livestock farming, biomass power generation, papermaking, and engineered wood products industries, and are a multi-functional and efficient agricultural waste treatment and resource utilization device.

[0003] However, some existing straw shredders have the following shortcomings: 1. When the shredder is working, the work area is shrouded in dust raised by the machine while shredding straw. People entering the area become covered in dust within 20 minutes, their breath coming in mouths and noses filled with grime. 2. The straw processed by the shredder is generally collected in the fields by balers. During baling, small branches, stones, and foreign objects such as rotary tiller blades, screws, and bolts inevitably get mixed into the straw bales. When these straw bales enter the shredder, the machine operates at a high speed of 3000 revolutions per minute. The blades, while shredding and striking the straw, scatter the mixed stones, branches, and metal foreign objects everywhere at speeds comparable to bullets. If these objects hit workers, it can easily cause serious safety accidents. Therefore, this application aims to provide a protective cover structure for a straw shredder to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a protective cover structure for a shredder.

[0005] The technical solution of this utility model is: a protective cover structure for a shredder, comprising a shredder body and a protective mechanism, wherein the protective mechanism includes a protective barrel, a protective top cover and a support; the protective barrel is installed on the base of the shredder body via the support, and the protective top cover is positioned above the protective barrel, forming a closed space with the protective barrel, completely covering the space above the shredder body, preventing dust, straw chips and other substances stirred up during the operation of the shredder from escaping outside the protective barrel, that is, the protective mechanism can confine the dust and debris generated during the operation of the shredder inside the protective barrel, so that it can only be discharged through the discharge port of the shredder.

[0006] Furthermore, the protective barrel consists of a cylindrical body and two steel rings, which are respectively located at the upper and lower ends of the cylindrical body. The relevant dimensions of the protective barrel are adapted to the body of the shredder.

[0007] Furthermore, the cylinder and the steel ring are connected together by welding, and there are no gaps at the connection between the cylinder and the steel ring to prevent material leakage.

[0008] Furthermore, a sealing gasket is installed between the lower end of the protective barrel and the base of the shredder body. This prevents the contents of the barrel from leaking out through the gap between the protective barrel and the base.

[0009] Furthermore, since the base of the shredder does not rotate, the protective mechanism fixed to the base will also not rotate.

[0010] Furthermore, the protective barrel, protective cover, and support frame are all made of metal.

[0011] Furthermore, the steel ring of the protective barrel is made of stainless steel, and the thickness of the barrel body is not less than 3mm. This effectively prevents metal foreign objects from impacting and penetrating the barrel body. Preferably, the steel ring is made of square steel.

[0012] Furthermore, the brackets are fixedly connected to the base, and there are multiple brackets evenly distributed around the circumference; the protective barrel is placed in the circle formed by the brackets, and the protective barrel is fixedly connected to the brackets. Preferably, the brackets are made of square steel and there are 8 of them.

[0013] Furthermore, the connection point between the bracket and the protective barrel is located on the steel ring.

[0014] Furthermore, the protective barrel and the support frame are connected by welding or by bolts for detachable connection.

[0015] Furthermore, a cleaning port is provided on the side wall of the protective barrel, and a baffle is installed at the cleaning port. When the protective barrel is filled with dust and debris after a period of use, the baffle at the cleaning port can be opened manually to clean the inside of the barrel.

[0016] Furthermore, the protective top cover and the protective barrel are detachably connected for easy loading, and are sealed to prevent leakage.

[0017] Furthermore, an observation port can be installed on the side wall of the protective barrel, with transparent bulletproof glass at the observation port, which is used to view the situation inside the barrel.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: By adopting the protective cover structure of this application, dust and impurities generated during the operation of the shredder are effectively collected and confined within the protective cover structure. The protective cover structure completely blocks the outward emission of dust, ensuring a clean working environment and protecting the respiratory health of workers. Simultaneously, the protective cover structure also strictly confines splashes generated during processing inside, effectively preventing them from flying out and injuring people, thus comprehensively protecting the personal safety of workers. Furthermore, the collected impurities and dust can be reused as fuel or fertilizer after subsequent processing. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides a protective cover structure for a shredder, including a shredder body 3 and a protective mechanism. The protective mechanism includes a protective barrel 1, a protective top cover 2, and a bracket 4. The protective barrel 1 is installed on the base 31 of the shredder body 3 via the bracket 4. The protective top cover 2 is positioned above the protective barrel 1 and can form a closed space with the protective barrel 1, completely covering the space above the shredder body 3. This prevents dust, straw chips, and other substances stirred up during the operation of the shredder from escaping outside the protective barrel 1. In other words, the protective mechanism can confine the dust and debris generated during the operation of the shredder inside the protective barrel 1, so that they can only be discharged from the discharge port of the shredder.

[0024] In this embodiment, the protective barrel 1 consists of a cylindrical body 13 and a steel ring. The cylindrical body 13 is a cylinder with a diameter of 3700mm and a height of 1500mm, rolled from a 3mm thick steel plate. The steel ring includes an upper steel ring 11 and a lower steel ring 12, which are respectively located at the upper and lower ends of the cylindrical body 13. The steel ring is made of 40x40x2 square steel with a diameter of 3700mm. The cylindrical body 13 and the steel ring are welded together, and there are no gaps at the connection between the cylindrical body 13 and the steel ring to prevent material leakage. The protective top cover 2 is also made of 3mm steel plate.

[0025] In this embodiment, the height of the bracket 4 is 2500mm, and all of them are made of 40x60x3 square steel. There are 8 brackets 4, which are evenly arranged in a circle on the base 31 of the body 3 of the shredder. The lower end of the bracket 4 is welded and fixed to the base 31, and the upper end of the bracket 4 is welded and connected to the protective barrel 1, and the connection point is located on the steel ring.

[0026] In this embodiment, a sealing gasket is used to seal the lower end of the protective barrel 1 with the base 31 of the shredder body 3. The sealing gasket is a dustproof rubber gasket.

[0027] In this embodiment, the base 31 of the shredder body 3 does not rotate, so that the protective mechanism fixed on the base 31 will also not rotate, thus making the protective mechanism work more stably.

[0028] In this embodiment, the protective cover structure, once installed on the shredder, can effectively block dust from escaping, ensuring a clean working environment. At the same time, the protective cover structure can also strictly confine the splashes generated during processing inside the protective barrel, effectively preventing them from flying out and injuring people, thus protecting the personal safety of the workers.

[0029] In some other embodiments, the protective barrel 1 and the bracket 4 can also be detachably connected by bolts for easy assembly and disassembly. In other embodiments, a cleaning port can be provided on the side wall of the protective barrel 1, and a baffle is provided at the cleaning port. After a period of use, the inner wall of the protective barrel 1 will be covered with dust and other debris. The baffle at the cleaning port can be manually opened to clean and collect the contents of the barrel.

[0030] In some other embodiments, an observation port may be provided on the side wall of the protective barrel 1, and the observation port is provided with transparent bulletproof glass. The observation port is used to view the situation inside the barrel.

[0031] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
