Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and specifically relates to an anti-blocking structure for crushers. Background Art

[0002] The design of the anti-blocking structure of crushers is the key to improving their efficiency and reliability. This design ensures uniform feeding and smooth flow of materials and effectively handles the problem of material jamming by optimizing the feeding system, improving the shape of the crushing chamber, adopting an automatic control system, and using wear-resistant and low-adhesion materials. With the development of technology, the application of intelligent and modular designs, and the use of new composite materials have further improved the anti-blocking performance of crushers, making the equipment more efficient and economical.

[0003] After retrieval, the existing patent (Publication No.: CN213255026U) discloses an anti-blocking device for crushers, which includes a crusher and a frame. An inlet guiding port is arranged at the upper part of the frame, the lower part of the frame is threadedly connected to the inlet of the crusher, a guiding plate is slidably connected inside the frame, a first cylinder is arranged on the left side of the frame, a mounting plate is threadedly connected to the piston rod of the first cylinder, a material taking port is opened on one side of the frame close to the mounting plate, a rotating plate is hinged to the frame at the position of the material taking port, a reinforcing rib is threadedly connected to the rotating plate, a cover plate is arranged at the lower part of the reinforcing rib, sealing strips are arranged around the cover plate, and second cylinders are hinged to the front and rear sides of the frame respectively, and the piston rods of the second cylinders are hinged to the rotating plate. The beneficial effects of the utility model are: good sealing performance, reducing the overflow of dust and debris, and the structural strength of its material taking port is relatively high.

[0004] However, during the actual use of the above scheme, if a blockage occurs, it is time-consuming and laborious to manually remove the stuck raw materials. At the same time, manually removing the stuck raw materials requires the operator to directly contact the working part of the machine, which may pose a safety hazard. If the operation is improper, it may lead to accidental injuries or more serious safety accidents.

[0005] Therefore, the utility model provides an anti-blocking structure for crushers. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem that it is time-consuming and laborious to manually remove the stuck raw materials when a blockage occurs, the utility model proposes an anti-blocking structure for crushers.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A material jamming prevention structure for a crusher according to the present utility model includes a crushing box. At the bottom of the front end on the left side of the crushing box, a first support plate is fixedly connected. At the top of the crushing box, a feeding box is fixedly connected. On the outside of the feeding box, front and rear opposite feeding hoppers are fixedly connected. At the top of the first support plate, a motor is fixedly connected. At the output end of the motor, a driving gear is fixedly connected. On the right side of the driving gear, a second crushing rod is fixedly connected. The second crushing rod is rotatably connected to the crushing box. Behind the driving gear, a driven gear is meshingly connected. On the right side of the driven gear, a first crushing rod is fixedly connected. The first crushing rod is rotatably connected to the crushing box. On the left side of the driven gear, a driving sprocket is fixedly connected. On the outside of the driving sprocket, a transmission chain is meshingly connected. On the inner side at the top of the transmission chain, a driven sprocket is meshingly connected. On the right side of the driven sprocket, a driving pulley is fixedly connected. On the right side of the driving pulley, an eccentric wheel is fixedly connected. Inside the eccentric wheel, a transmission rod is rotatably connected. At the bottom of the transmission rod, a hinge frame is rotatably connected. At the bottom of the hinge frame, a buffer assembly is provided. At the bottom of the buffer assembly, a connecting frame is provided. At the bottom of the connecting frame, a pressing rod is fixedly connected. On the outside of the middle end of the connecting frame, a limiting assembly is provided. At the top of the feeding box, left and right opposite second support plates are fixedly connected. The second support plates are rotatably connected to the driving pulley;

[0008] Through the above technical solution, the motor drives the first crushing rod and the second crushing rod to rotate in opposite directions simultaneously by using the driving gear and the driven gear, so as to crush the raw materials. At the same time, the driven gear drives the driven sprocket to rotate by using the driving sprocket and the transmission chain, and the driven sprocket drives the eccentric wheel to rotate by using the driving pulley. Thus, the eccentric wheel drives the limiting sleeve and the pressing rod to move up and down reciprocally by using the transmission rod, the hinge frame and the buffer assembly, and presses the raw materials reciprocally, so as to ensure that the raw materials enter the crusher more evenly and compactly, reduce the voids, which helps to improve the working efficiency of the crusher and make the crushing process more continuous and smooth.

[0009] Further, the buffer assembly includes a spring. At the top inside the hinge frame, a spring is fixedly connected. The bottom end of the spring is fixedly connected to the connecting frame. The connecting frame is slidably connected to the hinge frame. On the outside of the bottom end of the hinge frame, left and right opposite sliding grooves are opened. On the outside of the top end of the connecting frame, left and right opposite sliding blocks are fixedly connected. The sliding blocks are slidably connected to the sliding grooves;

[0010] Through the above technical solution, a buffer is provided between the hinge frame and the connecting frame by the spring, so as to leave a buffer space between the raw materials and the pressing rod and avoid affecting the normal operation of the equipment.

[0011] Further, the limiting component includes a support frame. A limiting sleeve is slidably connected to the outer side of the middle end of the connecting frame. The limiting sleeve is fixedly connected with the support frame on the outside, and the support frame is fixedly connected with the inner wall of the feeding box.

[0012] Through the above technical solution, the connecting frame is limited by the support frame and the limiting sleeve, so as to limit the operating angle of the connecting frame.

[0013] Further, the inner wall of the feeding box is fixedly connected with guard nets that are opposite to each other left and right. The outer wall of the feeding box is fixedly connected with filter nets that are opposite to each other left and right. A fan blade is rotatably connected to the middle end of the filter net. A driven pulley is fixedly connected to the outside of the fan blade. A transmission belt is rotatably connected to the outside of the driven pulley. The inner side of the top end of the transmission belt is rotatably connected with a driving pulley.

[0014] Through the above technical solution, the guard nets and the filter nets are fixed by the feeding box at the same time. At the same time, the driving pulley drives the driven pulley and the fan blade to rotate through the transmission belt, so that the air inside the feeding box is extracted and discharged outwards through the fan blade. At the same time, dust and impurities are filtered by the filter net.

[0015] Further, the same driven gears and driving sprockets are arranged at the outer ends of both sides of the first crushing rod. The same driving gears are meshed with the front ends of the driven gears on both sides.

[0016] Through the above technical solution, the motor first drives the driving gear to rotate, and at the same time drives the second crushing rod to rotate through the driving gear, so that the driving gear on the right side can be driven by the second crushing rod, and the driven gears and driving sprockets at the rear can be driven by the driving gears on both sides at the same time to drive the top structure.

[0017] Further, anti-slip layers are arranged on the inner outer walls of the driving pulley and the driven pulley and the inner outer wall of the transmission belt.

[0018] Through the above technical solution, the friction between the driving pulley, the driven pulley and the transmission belt is increased through the anti-slip layer.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. For the anti-blocking structure of the crusher of the present utility model, the eccentric wheel drives the connecting frame and the pressing rod to move up and down reciprocally, so that the raw materials are pressed down by mechanical means, which can ensure that the raw materials enter the crusher more evenly and compactly, reduce the gaps, which helps to improve the working efficiency of the crusher and make the crushing process more continuous and smooth.

[0021] 2. The anti-jamming structure of a crusher according to the present utility model drives a fan blade to rotate through a driving belt and a driven pulley by an active pulley, so as to extract the air inside the feed box, and at the same time discharge it outwards, and filter dust and impurities through a filter screen, thereby performing dust removal treatment on the dust and impurities generated during the operation of the equipment.
