[0054] like Figures 1 to 6 As shown, this embodiment provides a blockage-resistant crusher, including a crusher body 100, wherein the crusher body 100 is provided with a feed hopper 40, through which materials are transported into a crushing chamber of the crusher body 100, and a crusher 50 is provided in the crushing chamber of the crusher body 100, and the crusher 50 is driven by a drive system 10, and the crusher 50 is driven by the drive system 10 to crush the materials, and the drive end of the drive system 10 is connected to a belt drive 20, and is connected to a crushing main shaft of the crusher 50 through the belt drive 20.

[0055] In this embodiment, by starting the driving system 10, the driving system 10 drives the belt drive 20, and the belt drive drives the crusher 50 to rotate to crush the materials.

[0056] When the crusher is crushing materials, the raw materials entering the crusher are uneven in size, especially if some materials are mixed with large pieces of raw materials, which makes it impossible to effectively crush them, which will increase the load of the crusher and cause the crusher to be blocked. To solve the above technical problems, please refer to Figures 1 to 6 As shown, a screening system 70 is provided on one side of the crusher body 100, and the screening system 70 includes a screening storage box 702, on the bracket of which a screening box 704 is fixedly mounted by means of fastening screws or the like, and a pre-treatment crusher is provided in the screening box 704, which is driven by a rotating motor 701.

[0057] In this embodiment, the pre-processing crusher is driven by the rotating motor 701 to crush the raw material and perform preliminary processing on the raw material.

[0058] Furthermore, a sifter 705 is disposed in the screening box 704 , and the sifter 705 and the screening box 704 are detachably connected.

[0059] In this embodiment, the raw materials to be processed are placed in the screening box 704, and by starting the rotating motor 701, the pre-treatment crusher is driven by the rotating motor 701 to crush the raw materials. The crushed raw materials are screened by the screener and fall into the screening storage box 702 below. At this time, the larger pieces of preliminary crushed raw materials are blocked in the screening box 704, and then the staff puts the screened preliminary crushed raw materials into the crusher for re-crushing. The utility model has a simple structure, and the screening system ensures that the size of the materials entering the crushing chamber is relatively uniform, reduces the load of the crusher, and prevents the crusher from being blocked.

[0060] In order to improve the application of the screening system in practical applications, please refer to Figures 1 to 6 As shown, the crusher body 100 has a tilted screen built in, a discharge port (not noted in the figure) is opened between the discharge hopper 401 of the crusher body 100 and the screen, and a discharge plate 60 is provided on the outer wall of the crusher body 100 at the discharge port, and the discharge plate 60 is fixedly installed below the discharge port of the crusher body 100 by fastening screws, and the discharge plate 60 is tilted, and the inclination angle is 30-55°.

[0061] In this embodiment, after the material crushed by the crusher is screened by the screen, the material that meets the standards falls into the discharge hopper 401 through the screen and is discharged through the discharge hopper 401, while the material that does not meet the standards remains on the screen and flows to the lower material plate through the inclined screen, and is transported to the screening system 70 through the lower material plate for further crushing, thereby improving practicality.

[0062] See also Figures 1 to 6 As shown, the pre-treatment crusher includes a rotating shaft 706, the driving end of the rotating shaft 706 is connected to the driving shaft of the rotating motor 701 through a bearing assembly, and at least one group of hammering mechanisms 707 are arranged on the rotating shaft 706. The hammering mechanism 707 includes a pillar 7072, and the pillar 7072 is installed on the rotating shaft 706 by a fixed connection method such as fastening screws, and a crushing knife 7071 is fixedly installed on the pillar 7072.

[0063] In this embodiment, by starting the rotating motor, the rotating motor 701 is used to drive the rotating shaft 706 to rotate, thereby driving the crushing knife 7071 on the rotating shaft 706 to rotate, and the crushing knife is used to crush the raw material.

[0064] Furthermore, a connecting shaft 706 is fixedly installed in the mounting hole of the crushing blade 7071 through a positioning pin, and a crushing disk 7075 is welded on the connecting shaft, and the crushing disk 7075 is arranged in a fan shape, and at least one group of protrusions 7074 is arranged on the crushing disk 7075. The crushing disk 7075 arranged in a fan shape can quickly crush the material, thereby reducing energy consumption to a certain extent.

[0065] See also Figures 1 to 6 As shown, the sifter 705 includes two groups of first sieve plates 7052 and second sieve plates 7053 arranged in parallel in an upper and lower manner, the first sieve plate 7052 is provided with multiple groups of first sieve holes 7051 evenly distributed, and the second sieve plate 7053 is provided with multiple groups of second sieve holes 7054 evenly distributed.

[0066] Furthermore, a spring 7055 is provided between the first screen plate 7052 and the second screen plate 7053, and both ends of the spring 7055 are fixedly mounted on the first screen plate 7052 and the second screen plate 7053 by fastening bolts, respectively.

[0067] In this embodiment, in order to prevent blockage, two groups of first screening plates 7052 and second screening plates 7053 are added and arranged in parallel up and down, and a spring 7055 is arranged between the first screening plates 7052 and the second screening plates 7053. When in use, the hammering mechanism 707 is driven to rotate by the rotation of the rotating shaft, and when the hammering mechanism rotates, it hammers the screener inside the screening box to generate vibration. At this time, the vibration force is transmitted to the spring 7055 through the screening plate, and the spring produces a certain elastic deformation. When the vibration force disappears, the spring rebounds, and the rebound force generated by the spring causes the screening plate to further vibrate, thereby preventing the material from being blocked.

[0068] The use process and working principle of this utility model:

[0069] In actual application, the raw materials to be processed are first placed in the screening box 704, and the rotating motor 701 is started to drive the pre-treatment crusher to crush the raw materials. The crushed raw materials are screened by the screener and fall into the screening storage box 702 below. The screened raw materials are then placed in the crushing chamber through the feed hopper, and then the driving system 10 is started, the driving system 10 drives the belt drive 20, and the belt drive drives the crusher 50 to rotate to crush the materials.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
