Description

Technical Field

[0001] The utility model belongs to the technical field of rock salt crushing, and particularly relates to a two-stage crushing device. Background Art

[0002] The rock salt two-stage crushing device is a device specially designed for processing rock salt. First, a pair of rotating crushing rollers are used to crush large pieces of rock salt into smaller particles. Then another pair of rotating crushing rollers are used to further squeeze and crush these particles to achieve the required fineness.

[0003] The existing two-stage rock salt crushing device uses two rotating crushing rollers to crush the rock salt into small pieces, and then squeezes and crushes the rock salt through the two rotating crushing rollers. However, the crushing rollers will adhere to the rock salt when crushing the rock salt. In order to avoid affecting the crushing quality, personnel need to disassemble the crushing device and manually clean the crushing rollers. Frequent shutdowns and manual cleaning greatly reduce the efficiency of rock salt crushing and increase non-production time. It not only consumes manpower, but also increases maintenance costs, including additional labor costs and potential equipment damage risks. Utility Model Content

[0004] In view of this, the utility model addresses the shortcomings of the existing technology and provides a two-stage crushing device, which is equipped with a cleaning brush mechanism that can automatically scrape off the rock salt adhered to the two crushing rollers, thereby reducing downtime, improving the operating efficiency of the overall equipment, reducing dependence on manpower, and saving labor costs and maintenance costs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a two-stage crushing device, including a crushing box, two crushing rollers are rotatably provided inside the crushing box, the front and rear positions of the two crushing rollers correspond, and the right ends of the two crushing rollers are provided with two gears 1 that are meshed with each other; two crushing rollers are rotatably provided inside the lower end of the crushing box, the front and rear positions of the two crushing rollers correspond, and the right ends of the two crushing rollers are provided with two gears 2 that are meshed with each other; a motor 1 is provided on the right side of the crushing box through a mounting plate, and the output shaft of the motor 1 is connected to the right end of the gear 1 on the rear side through a coupling; a Motor 2 and the output shaft of motor 1 are connected to the right end of gear 2 on the rear side through a coupling. A cleaning scraping brush mechanism for cleaning the scraping brush of the crushing roller is provided at the lower end of the interior of the crushing box. The cleaning scraping brush mechanism includes a guide column provided at the lower end of the interior of the crushing box, and a scraping brush plate is slidingly provided on the outer arc surface of the guide column. Two crushing rollers are installed in conjunction with a scraping brush plate. A screw rod threadedly connected to the scraping brush plate is rotatably provided on the front side of the interior of the crushing box. An electric drive unit for driving the screw rod to rotate is provided on the left side of the crushing box. The electric drive unit includes motor 3 provided on the left side of the crushing box. The output shaft of motor 3 is connected to the left end of the screw rod through a coupling.

[0006] As a further improvement of the present invention, a control panel is provided on the front side of the crushing box, and motor one, motor two, and motor three are all electrically connected to the control panel.

[0007] As a further improvement of the present invention, two material guide plates are provided inside the crushing box, and the two material guide plates are both located between the two crushing rollers and the two crushing rollers.

[0008] As a further improvement of the present invention, a feed shell is provided in the feed opening opened at the upper end of the crushing box, and a discharge plate is provided in the mounting opening opened at the lower end of the crushing box.

[0009] As a further improvement of the present invention, a support frame is provided at the lower end of the crushing box, the crushing box and the support frame are fixed by welding, and a plurality of mounting holes are provided inside the support frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] First, by controlling and turning on motor one and motor two, the output shaft of motor one drives the rear gear one to rotate and drives the front gear one meshing with it to rotate, so that the two crushing rollers rotate toward each other. At the same time, the output shaft of motor one drives the rear gear two to rotate and drives the front gear two meshing with it to rotate, so that the two crushing rollers rotate toward each other. Then, the personnel add the rock salt blocks to be crushed from the inside of the feed shell, so that they fall between the two crushing rollers for crushing, and fall between the two crushing rollers for more fine crushing. The crushed rock salt falls on the discharge plate, which can quickly achieve two-stage crushing and discharge of rock salt.

[0012] Secondly, the crushed rock salt can be guided to between the two crushing rollers for crushing through the guide plate, thereby improving the stability of the rock salt crushing.

[0013] Thirdly, by controlling the operation of motor 2, the two crushing rollers are rotated, and then by controlling the operation of motor 3, the output shaft drives the screw to rotate so that the scraper plate moves to the right under the restriction of the limit guide column and cooperates with the rotating crushing roller to scrape off the rock salt adhered to its surface, reducing the involvement of personnel. A cleaning scraper mechanism is provided to automatically scrape off the rock salt adhered to the two crushing rollers, which can reduce downtime, improve the operating efficiency of the overall equipment, reduce dependence on manpower, and save labor costs and maintenance costs.

[0014] Fourthly, the support frame is used to provide stable support for the crushing device, and the internal mounting holes can also be fixed to the ground by bolts, making the crushing device more stable and indirectly improving the two crushing qualities of rock salt.
