Description

Technical Field

[0001] This utility model relates to the technical field of double-layer roller crushers, specifically a double-layer roller crusher. Background Technology

[0002] A double-roll crusher, also known as a twin-roll crusher or a double-roll crusher, is a mechanical device that crushes materials by applying compression, shearing, and grinding forces through the relative rotation of two sets of parallel cylindrical rollers. During operation, the material is crushed under high pressure and shearing forces within the gap between the two rollers. When encountering highly viscous materials, the material tends to adhere to the outer side of the cylindrical rollers. While scraping structures are typically installed, existing scraping structures are located inside the device, making them difficult to replace and increasing the burden on the user. Therefore, we propose a new double-roll crusher. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a double-layer roller crusher, including a crushing box, a top plate, a support plate, a crushing component, and a scraping component. The crushing box has an installation hole on its outer side, a limit block is fixedly installed at the front end of the crushing box, the top plate is fixedly installed at the top of the crushing box, a feed hopper is fixedly installed at the top end of the top plate, the support plate is fixedly installed at the front end of the crushing box, the crushing component is fixedly installed on the crushing box, and the scraping component includes a crossbar inserted into the installation hole, a scraper fixedly installed on the left side of the crossbar, a stop block fixedly installed at the front end of the crossbar, a sliding groove opened on the rear side of the stop block, and a fastener threadedly connected to the crossbar.

[0005] Preferably, a support rod and a discharge hopper are fixedly provided at the bottom of the crushing box, and scale lines are provided on the rear side of the crushing box.

[0006] Preferably, the crushing assembly includes an upper crushing roller connected to the crushing box by a bearing, a lower crushing roller connected to the crushing box bearing and connected to the upper crushing roller belt, and a rotary motor fixedly disposed at the front end of the lower crushing roller.

[0007] Preferably, there are two crushing components, which are symmetrically distributed on the crushing box.

[0008] Preferably, a slot is provided on the rear side of the crossbar, and the cross section of the slot is square.

[0009] Preferably, the fastener is composed of a nut and a metal washer welded together.

[0010] Preferably, it also includes a reference rod, which is inserted into the slot, and the cross-section of the reference rod is square.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: the fasteners of the scraping component can be directly rotated to disengage from the crossbar. After disengagement, the crossbar can be directly pulled out, allowing for quick disassembly of the scraping component. Then, the crossbar can be inserted into the crushing box through the mounting hole. Next, the stop block is rotated until the slide groove of the stop block engages with the limiting block. Then, the fasteners are rotated to fix the crossbar, allowing for quick installation of the scraping component. This process does not require disassembly of the device, thus reducing the burden on the user when replacing the scraper. At the same time, the reference rod can be inserted into the slot, and the crossbar can be moved by loosening the fasteners. During movement, the position of the scraper can be precisely adjusted by referring to the position of the reference rod on the scale line, so as to accurately adjust the distance between the scraper and the crushing roller.
