Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically, to a spiral crusher. Background Technology

[0002] A spiral crusher, also known as a spiral pulverizer, is a mechanical device that uses the shearing, squeezing, and friction generated by the rotation of spiral blades to crush, grind, or mix materials, thus achieving spiral crushing operation.

[0003] In existing publicly available literature, patent publication number CN221821255U discloses a screw conveyor mechanism and a crusher. This technology uses auger blades connected to the motor output shaft via a coupling. The lower end of the pipe has a feed inlet, and the upper end has a discharge outlet. Multiple suction ports are evenly distributed on the pipe, each equipped with a filter screen. These suction ports are connected to a negative pressure fan and a powder collection bag via pipes. This application uses suction to collect the powder from the crushed material, preventing it from entering the subsequent cleaning process. However, this patent has the following problems.

[0004] While spiral crushers can perform spiral crushing when crushing raw materials, it is difficult to switch to different crushing and conveying positions according to actual needs after crushing and conveying, resulting in poor adjustability of crushing and conveying. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a spiral crusher, comprising a crushing box, a bolt cylinder, and a lower discharge pipe. The bolt cylinder is fixedly connected to the bottom end of the crushing box, and the lower discharge pipe is fixedly connected to the outer wall of the bolt cylinder. The outer wall of the lower discharge pipe is provided with a crushing switching guide assembly. The crushing switching guide assembly includes a sleeve fixedly disposed on the outer wall of the lower discharge pipe, and a switching motor is fixedly installed on one side of the sleeve. The output end of the switching motor is fixedly connected to a guide hopper, and the output end of the switching motor is rotatably connected to the sleeve. A rotary motor is installed on one side of the crushing box, and a cutting and crushing blade is fixedly connected to the output end of the rotary motor. Both the cutting and crushing blade and the output end of the rotary motor are rotatably connected to the crushing box. A guide filter is provided below the cutting and crushing blade, and the guide filter is fixedly connected to the crushing box.

[0006] Preferably, the guide hopper has a circular arc cross-section and a smooth inner wall. The switching motor drives the guide hopper to rotate. The guide hopper is made of stainless steel. A spiral auger is installed inside the bolt cylinder, and a drive motor is fixedly installed at the top of the bolt cylinder to drive the spiral auger to rotate. A support frame is fixedly installed at the bottom of the crushing box near its edge to support the rotating motor. A discharge hopper is fixedly connected to the top of the crushing box, and the inner wall of the discharge hopper is smooth.

[0007] In use, the material is fed into the cutting and crushing blades through the hopper. The cutting and crushing blades are driven to rotate by a rotary motor. The cutting and crushing blades rotate and crush the material inside the crushing chamber. The spiral auger is driven to rotate by a transmission motor. The spiral auger carries the crushed material to the lower discharge pipe. The switching motor drives the guide hopper to rotate counterclockwise. The guide hopper carries the crushed material to tilt to the designated rotation position of the buffer plate.

[0008] Preferably, both ends of the feed hopper are fixedly connected to a support column, and the outer wall of the support column is provided with a limiting buffer assembly; the limiting buffer assembly includes a support ring fixedly disposed on the outer wall of the support column, a buffer plate is fixedly connected to one end of the support column, and an arc-shaped retaining ring is fixedly connected to one side edge of the buffer plate.

[0009] When this technology is in use, the guide hopper drives the support ring to rotate counterclockwise, the support ring drives the pillar to rotate counterclockwise, and the buffer plate drives the arc-shaped retaining ring to rotate counterclockwise. The crushed raw material is buffered along the buffer plate and then discharged into the arc-shaped retaining ring.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a crushing and switching material guiding component. The rotary motor drives the cutting and crushing blade to rotate and discharges it into the guide hopper through the lower discharge pipe. After the crushed material enters the guide hopper, the connecting strip supports the switching motor. The switching motor drives the guide hopper to rotate counterclockwise. The guide hopper drives the crushed material to tilt to the buffer plate position. It can be switched to different crushing and conveying positions according to actual use needs, and the switching crushing and conveying is more adjustable.

[0012] 2. This utility model uses a guide hopper to drive the support ring to rotate counterclockwise, and a buffer plate to drive the arc-shaped retaining ring to rotate counterclockwise. The crushed raw material is buffered along the buffer plate and discharged through the arc-shaped retaining ring. It can transport and discharge the crushed raw material in different directions, and the buffer discharge efficiency is greatly improved. Attached Figure Description

[0021] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, a spiral auger 10 is installed inside the bolt cylinder 2, and a drive motor 11 is fixedly installed at the top of the bolt cylinder 2. The drive motor 11 drives the spiral auger 10 to rotate, so that the spiral auger 10 rotates inside the bolt cylinder 2 to achieve rotation operation. A support frame 12 is fixedly installed at the bottom of the crushing box 1 near its edge. The support frame 12 supports the rotary motor 7 to increase the stability of the rotary motor 7.
