[0026] In this embodiment, the raw materials are placed into the crushing box 6 through discharge, and the power device is started to drive the rotating shaft 101 to rotate. The rotation of the rotating shaft 101 will synchronously drive the scraper 3 and the mounting frame 4 to rotate. The scraper 3 is against the inner wall of the crushing box 6, so that the rotation of the scraper 3 will scrape off the raw materials stuck on the inner wall of the crushing box 6, and at the same time, the input raw materials are turned over, and the large particles in the lower layer are turned to the upper layer, and the rock salt raw materials are crushed by the crushing roller 401 rotatably installed on the mounting frame 4, so that the crushing effect is better. The mounting frame 4 is fixedly connected to the rotating shaft 101 through the telescopic rod 5, so as to limit the position of the crushing roller 401, avoid the position of the crushing roller 401 from being misplaced, and avoid the problem of the crushing roller 401 being thrown up and hitting the inner wall of the device.

[0027] Among them, in order to achieve the purpose of driving the crushing box 6 to rotate, the present device adopts the following technical scheme: a power motor 102 is fixedly installed on the outer wall of one side support 1, the output end of the power motor 102 is fixedly connected to the rotating shaft 101, and the other end of the rotating shaft 101 is fixedly connected to the first pulley 103, and a connecting shaft 2 is rotatably installed in the other side support 1, a second pulley 201 is fixedly installed at one end of the connecting shaft 2, and a first gear 202 is fixedly installed at the other end of the connecting shaft 2, a transmission belt 104 is sleeved on the first pulley 103 and the first gear 202, a second gear 602 is fixedly installed on one side of the support 1, the second gear 602 cooperates with the first gear 202, a scraper 403 is fixedly installed on the mounting frame 4, and the scraper 403 cooperates with the crushing roller 401.

[0028] By starting the power motor 102, the rotating shaft 101 can be driven to rotate, and the rotation of the rotating shaft 101 can drive the first pulley 103 to rotate. The first pulley 103 is connected to the second pulley 201 through the transmission belt 104, so that the rotation of the first pulley 103 can drive the second pulley 201 to rotate, and the rotation of the second pulley 201 can drive the first gear 202 to rotate. The first gear 202 cooperates with the second gear 602, so that the rotation of the first gear 202 can drive the crushing box 6 to rotate. The rotation of the crushing box 6 can first adjust the position of the discharge chute to facilitate the placement or discharge of raw materials. Secondly, the crushing box 6 can rotate alone, so as to drive the internal raw materials to turn over, avoid the problem that large particles of raw materials are accumulated in the lower layer and are difficult to contact with the crushing roller 401, thereby improving the crushing efficiency. The scraper 403 fits the inner wall of the mounting frame 4, and can scrape off the raw materials stuck on the mounting frame 4.

[0029] Among them, in order to achieve the purpose of fixing the sealing plate 7, the present device is implemented by the following technical scheme: a first crushing knife 601 is fixed to the inner wall of the crushing box 6, a second crushing knife 701 is fixedly installed on the sealing plate 7, a tooth groove 301 is provided on the scraper 3, and the tooth groove 301 cooperates with the first crushing knife 601 and the second crushing knife 701, a rolling groove 402 is provided on the crushing roller 401, and the rolling groove 402 cooperates with the first crushing knife 601 and the second crushing knife 701, the telescopic rod 5 includes a first connecting rod 501 and a second connecting rod 502, a connecting hole 503 is provided in the first connecting rod 501, a return spring 504 is fixedly installed in the connecting hole 503, and the other end of the return spring 504 is fixedly connected to the second connecting rod 502, a spring pad 803 is fixedly installed on the limit latch 802, an extrusion spring 804 is sleeved on the limit latch 802, and a pull ring 805 is fixedly installed at one end of the limit latch 802.

[0030] Through the cooperation between the crushing knife and the tooth groove 301, the scraper 3 can be made to fit the inner wall of the crushing box 6 to scrape out the raw materials stuck between the gaps of the crushing knife. The crushing knife and the rolling groove 402 cooperate with each other to crush the raw materials. The extrusion spring 804 can provide a certain thrust for the spring pad 803. The spring pad 803 will drive the limit pin 802 to move when it is subjected to the thrust. The limit pin 802 moves and is inserted into the limit hole 703, thereby fixing the sealing plate 7 inside the discharge groove. The movable pull ring 805 can drive the limit pin 802 to move. The return spring 504 can provide a certain thrust for the second connecting rod 502, so that the second connecting rod 502 pushes the mounting frame 4 to fit the inner wall of the crushing box 6, so that the crushing roller 401 has a certain extrusion force, which cooperates with the centrifugal force of high-speed rotation to crush and crush the raw materials.

[0031] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, first start the power motor 102 to drive the crushing box 6 to rotate, so that the discharge slot rotates to the top, and move the pull ring 805 to drive the limit pin 802 to move out of the limit hole 703, thereby releasing the restriction on the sealing plate 7. At this time, the sealing plate 7 can be easily removed, and then the raw materials are added to the inside of the crushing box 6 through the discharge slot, and then the sealing plate 7 is installed into the discharge, and the power motor 102 is started to drive the crushing box 6, the scraper 3, and the crushing roller 401 to rotate. The crushing box 6 will flip over when it rotates, and the crushing roller 401 cooperates with the first crushing knife 601 to crush the added raw materials. The scraper 3 fits the inner wall of the crushing box 6, and can scrape off the raw materials stuck between the first crushing knife 601 to avoid the raw materials being tightly stuck inside the crushing box 6.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
