[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] The utility model discloses a raw salt crushing device, the structure of which is shown in the attached figure. Figure 1 ~Attached Figure 3 As shown, it includes a frame 1, a first roller 2 and a second roller 3 arranged side by side on the frame 1 at intervals, a conveyor belt 4 sleeved on the outer periphery of the first roller 2 and the second roller 3, a third roller 5 arranged just above the first roller 2 at intervals, a first cleaning component 6 for cleaning the conveying surface of the conveyor belt 4, and a second cleaning component 7 for cleaning the third roller 5.

[0029] Specifically, the rotation direction of the third roller 5 is opposite to that of the first roller 2. The first cleaning assembly 6 is arranged on the side of the frame 1 corresponding to the first roller 2, and is in contact with the conveying surface of the conveyor belt 4 to clean the raw salt that is crushed and adheres to the conveying surface of the conveyor belt 4. The second cleaning assembly 7 is arranged above the third roller 5, and is in contact with the surface of the third roller 5 to clean the raw salt that is crushed and adheres to the third roller 5.

[0030] By adopting the above structure, in actual application, the raw salt enters the gap between the first roller 2 and the third roller 5 along the conveyor belt 4 for extrusion and crushing, which is beneficial to improving the crushing efficiency and meeting the requirements of automated production; further, by setting the first cleaning component 6 to clean the raw salt adhered to the conveying surface of the conveyor belt 4 after crushing, it can not only help the crushed raw salt particles to enter the next process, but also prevent the raw salt particles remaining on the conveyor belt from falling to other places; at the same time, the second cleaning component 7 is cooperated to clean the third roller 5, so as to prevent the raw salt particles from affecting the crushing accuracy between the first roller 2 and the third roller 5.

[0031] In order to prevent the raw salt from gathering between the first roller 2 and the third roller 5 and affecting the crushing efficiency, in some embodiments, a scraper plate 8 is further included, which is arranged above the conveyor belt 4 and between the third roller 5 and the second roller 3. Thus, the height of the raw salt entering between the first roller 2 and the third roller 5 is limited by the distance between the scraper plate 8 and the conveyor belt 4, so as to improve the crushing efficiency.

[0032] In some embodiments, a batching hopper 9 is also included, and a discharge port of the batching hopper 9 is located above the conveyor belt 4, so that the discharge amount is controlled by the batching hopper 9 to avoid the accumulation of raw salt on the conveyor belt 4.

[0033] In some implementations, a screening component 10 is further included, and the screening component 10 is connected to the discharge side of the conveyor belt 4 to receive the crushed raw salt particles and screen and grade them.

[0034] Specifically, the screening assembly 10 includes a screening box 101 and a receiving tray 102. The receiving tray 102 is arranged at an angle, and its upper end is connected to the discharge side of the conveyor belt 4, and its lower end is connected to the screening box 101, so that the crushed raw salt particles are introduced into the screening box 101 through the inclined receiving tray 102 for screening and grading.

[0035] In this embodiment, the screening box 101 is a vibrating screening machine, which is common in the prior art and does not present any difficulty to those skilled in the art, and will not be described in detail herein.

[0036] The working process of the embodiment of the utility model is:

[0037] First, the raw salt is transported to the batching hopper 9 through the conveying device, and is evenly transported to the conveyor belt 4 through the discharge port of the batching hopper 9; then, the raw salt is scraped flat by the scraper plate 8 along the conveyor belt 4, and then enters between the first roller 2 and the third roller 5 for extrusion and crushing; the crushed raw salt falls onto the receiving tray 102 through the discharge side of the conveyor belt 4, and at the same time, the first cleaning component 6 and the second cleaning component 7 clean the conveyor belt 4 and the third roller 5 respectively; finally, the inclined receiving tray 102 guides the crushed raw salt particles into the screening box 101 for screening and grading.

[0038] As a specific implementation of the above embodiment, the first cleaning component 6 and the second cleaning component 7 both adopt a scraper cleaning structure, which does not present any difficulty to those skilled in the art and will not be described in detail here.

[0039] It can be seen from the above description that the beneficial effects of the embodiments of the utility model are:

[0040] The raw salt is transported by the conveyor belt 4 and crushed by the extrusion of the first roller 2 and the third roller 5, which can meet the requirements of industrial and automated production, and is convenient for cleaning, which is beneficial to improving the crushing efficiency; further, the conveyor belt 4 and the third roller 5 are cleaned by the first cleaning component 6 and the second cleaning component 7 respectively, which can prevent the raw salt particles from adhering to the conveyor belt 4 and the third roller 5, thereby helping to improve the crushing efficiency and the service life of the equipment; further, a material hopper 9 is provided for unloading and a scraper plate 8 is provided for leveling, so that the raw salt can be evenly introduced between the first roller 2 and the third roller 5, which is beneficial to improving the crushing efficiency; finally, a screening component 10 is provided to screen and grade the raw salt particles for the convenience of subsequent process use.

[0041] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
