DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 3 and Figure 4As shown, in this embodiment, a crushing device for compound fertilizer production includes a crushing box 1, which is characterized in that: two limit frames 301 are fixedly connected to the outer walls at both ends of the crushing box 1, and multiple crushing components 3 are installed on the two limit frames 301. The crushing component 3 includes four mounting blocks 302 that are slidably connected inside the two limit frames 301, and the same crushing roller 303 is rotatably connected relative to the two mounting blocks 302. The two crushing rollers 303 can cooperate with each other. A cleaning component 4 is installed at the bottom of the two crushing rollers 303, and the cleaning component 4 includes two extension blocks 401 fixedly connected to the outer walls of the bottom of the two mounting blocks 302. The same cleaning roller 402 is rotatably connected between the two extension blocks 401, and the cleaning roller 402 can fit with the crushing roller 303.

[0024] The rotating shaft fixing sleeve of the crushing roller 303 is provided with a pulley 1 403 , and the rotating shaft fixing sleeve of the cleaning roller 402 is provided with a pulley 2 404 . The pulley 1 403 and the pulley 2 404 are provided with the same belt 405 .

[0025] When the crushing roller 303 rotates, its rotating shaft will drive the pulley 1 403 to rotate synchronously, and the pulley 1 403 can drive the pulley 2 404 to rotate through the belt 405. The cleaning roller 402 installed between the two extension blocks 401 will be driven by the pulley 2 404 to rotate in the same direction, which can ensure that the surface of the crushing roller 303 is cleaned when passing through the cleaning roller 402, avoiding the debris attached to the surface of the crushing roller 303 affecting the processing.

[0026] like Figure 1 and Figure 4 As shown, a motor 304 is fixedly installed on the outside of multiple mounting blocks 302 at one end, and multiple motors 304 are coaxially fixed with multiple crushing rollers 303 respectively. A guide hopper 2 is fixedly connected to the top of the crushing box 1, and multiple discharge ports at the bottom of the guide hopper 2 correspond to the positions of multiple crushing components 3 respectively.

[0027] An extension plate 305 is fixedly connected to one end of the top outer wall of the crushing box 1, and a hydraulic cylinder 306 is fixedly installed on the top outer wall of the extension plate 305. The output end of the hydraulic cylinder 306 is fixedly connected to a driving plate 307. Multiple groups of guide grooves 308 are provided inside the driving plate 307. A group of guide grooves 308 consists of two symmetrically arranged oblique grooves. An extension column 309 is fixedly connected to the outer wall of one end of multiple mounting blocks 302 at one end, and the multiple extension columns 309 are slidably inserted into the multiple guide grooves 308 respectively.

[0028] First, adjust the distance between the two adjacent crushing rollers 303 to ensure that the processed compound fertilizer particles meet the composite requirements, which is conducive to increasing the practicality of the device. Start the hydraulic cylinder 306 on the top of the extension plate 305, and the output end of the hydraulic cylinder 306 drives the driving plate 307 to move downward. Since the mounting block 302 is restricted by the limit frame 301, the mounting block 302 can only move in the horizontal direction. At this time, the guide groove 308 can drive the two adjacent extension columns 309 and the mounting block 302 to approach each other, and then the two adjacent crushing rollers 303 will also approach each other. Finally, start the motor 304 to drive multiple groups of crushing rollers 303 to rotate at the same time. With the cooperation of the guide hopper 2, a large amount of compound fertilizer can be processed, which is conducive to improving processing efficiency.

[0029] like Figure 3 As shown, the transmission ratio of pulley 1 403 to pulley 2 404 is less than 1. When pulley 1 403 rotates one circle, pulley 2 404 rotates multiple circles, and then the cleaning roller 402 is also driven to rotate rapidly, thereby further increasing the cleaning effect.

[0030] like Figure 3 As shown, the bristles on the surfaces of the multiple cleaning rollers 402 are all made of steel wire, which has high hardness and elasticity, thereby ensuring that the cleaning work can proceed smoothly and also helping to improve the cleaning effect.

[0031] The utility model provides a crushing device for compound fertilizer production, and the specific working principle is as follows:

[0032] When the device is working, first adjust the distance between the two adjacent crushing rollers 303 to ensure that the processed compound fertilizer particles meet the composite requirements, which is conducive to increasing the practicality of the device. Start the hydraulic cylinder 306 on the top of the extension plate 305, and the output end of the hydraulic cylinder 306 drives the driving plate 307 to move downward. Since the mounting block 302 is restricted by the limit frame 301, the mounting block 302 can only move in the horizontal direction. At this time, the guide groove 308 can drive the two adjacent extension columns 309 and the mounting block 302 to move closer to each other, and then the two adjacent crushing rollers 303 will also move closer to each other. Finally, start the motor 30 4 can drive multiple groups of crushing rollers 303 to rotate simultaneously. With the cooperation of the guide hopper 2, a large amount of compound fertilizer can be processed, which is beneficial to improving processing efficiency. During this period, when the crushing roller 303 rotates, its rotating shaft will drive the pulley 1 403 to rotate synchronously. The pulley 1 403 can drive the pulley 2 404 to rotate through the belt 405. The cleaning roller 402 installed between the two extension blocks 401 will be driven by the pulley 2 404 to rotate in the same direction, which can ensure that the surface of the crushing roller 303 is cleaned when passing through the cleaning roller 402, so as to prevent the crushed particles attached to the surface of the crushing roller 303 from affecting the processing.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
