Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a safety protection structure for crushers. Background Art

[0002] The recycling of waste plastic products using crushers is an important part of today's environmental protection and resource recycling. This crusher is specially designed for waste plastics and can effectively break discarded plastic products into small pieces, providing convenience for subsequent processing and reuse.

[0003] Publication No. CN218111382U discloses a safety protection structure of a plastic crusher. The device places materials on the first feeding cylinder and the second feeding cylinder of the hopper respectively, and then the driving component drives the first feeding cylinder and the second feeding cylinder to rotate. As the first feeding cylinder and the second feeding cylinder rotate, the materials fall into the hopper, and then the pressing component presses the materials to the side close to the crusher body, which helps to prevent the waste of plastic products from splashing due to high brittleness during crushing, and reduces the risk of injury to workers caused by splashing materials. However, the patent still has the following problems in actual use:

[0004] The device causes the material to fall into the hopper through the rotation of the first feeding barrel and the second feeding barrel, and then the pressing component presses the material to the side close to the crusher body, which helps to prevent the waste of plastic products from splashing when crushed due to their high brittleness, and reduces the risk of injuries to workers caused by flying materials. However, when the device pours the material into the grooves on the outside of the first feeding barrel and the second feeding barrel, there is no shielding structure on the outside of the feeding barrel, which makes it easy for the material to fall from both sides of the feeding barrel. When the material is poured between the first feeding barrel and the second feeding barrel, the pressing plate may block the material and cause it to get stuck, causing inconvenience to the workers when using it.

[0005] A crusher safety protection structure is proposed to solve the above problems. Utility Model Content

However, when the device pours the materials into the grooves on the outer sides of the first feeding barrel and the second feeding barrel, since there is no shielding structure on the outer side of the feeding barrel, the materials are easily dropped from both sides of the feeding barrel, and when the materials are poured between the first feeding barrel and the second feeding barrel, the pressing plate may block the materials and cause them to get stuck, causing inconvenience to the workers when using them.

The design of the protective cover 201 can prevent dust and impurities from entering the expansion shell 102 and the crusher body 101, thereby affecting the service life of the crusher body 101, and bringing convenience to the workers when using it.

[0027] A retractable rod 209 is installed between the top of the lifting plate 205 and the inner side of the limit box 203, and a third telescopic spring 210 is sleeved on the outer side of the retractable rod 209. Through the design of the retractable rod 209 and the third telescopic spring 210, the lifting plate 205 is not easily deflected by the tension generated by the third telescopic spring 210.

[0029] Working principle: Before using this crusher safety protection structure, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, by placing the protective cover 201 on the top of the expansion shell 102, the clamping plate 202 cooperates with the protective cover 201 to be clamped and connected to the expansion shell 102, and then the lifting plate 205 is driven to move by rotating the screw 204, and the movement of the lifting plate 205 drives the rotation of the rotating rod 207, and then the rotating rod 207 pushes the movement of the plug plate 206. At this time, one side of the plug plate 206 is slidably connected with the slide groove 208, so that the plug plate 206 and the clamping plate 202 can be clamped and fixed, so that the effect of quickly installing and removing the protective cover 201 can be achieved, and then the protective cover 201 can be used to shield the two sides of the feeding barrel assembly 103 to avoid the phenomenon of material splashing and falling and injuring the staff, thereby improving the protection. The protective cover 201 is designed to prevent dust and impurities from entering the expansion shell 102 and the crusher body 101, thereby reducing the service life of the crusher body 101, which brings convenience to the staff when using it. The design of the retractable rod 209 and the third telescopic spring 210 can prevent the lifting plate 205 from being easily deflected by the tension generated by the third telescopic spring 210. The material is poured into the expansion shell 102 through the feed hopper 214. At this time, the fixing knob 213 is loosened to press the N-shaped rod 211, thereby driving the squeezing plate 212 to squeeze the falling material, thereby preventing the material from clogging the feeding barrel assembly 103 and affecting the material breakage effect, which brings practicality to the staff when using it.

[0030] When the crusher body 101 crushes the material, the crusher body 101 and the expansion shell 102 will shake. When the crusher body 101 shakes, the distance between the first fixed plate 302 and the second fixed plate 303 changes, so that the movable rod 307 rotates crosswise outward, and then the movable rod 307 pushes the slider 305 to slide inside the sliding box 304. At this time, the first telescopic spring 306 contracts to achieve a longitudinal buffering effect. At the same time, the position between the first rotating seat 308 and the second rotating seat 309 changes, so that the telescopic rod 310 rotates and contracts, and then the second telescopic spring 311 contracts, so as to achieve a lateral buffering effect. Through longitudinal and lateral buffering, the shock is absorbed layer by layer, thereby greatly reducing the shaking amplitude of the crusher body 101 and the expansion shell 102, thereby increasing the service life of the device while reducing noise, bringing convenience to the staff when using it, and through the design of the shock-absorbing rubber block 312, the buffering effect of the crusher body 101 can be better.

[0031] The crusher body 101, the expansion shell 102 and the feeding barrel assembly 103 are in the prior art. Publication No. CN218111382U discloses a safety protection structure for a plastic crusher, and the devices used therein are not described in detail here.
