The setting of the mounting groove 7 provides an installation space for the cross mounting plate 508, so that the cross mounting plate 508 can be quickly installed in the working box 1 or taken out from the working box 1 for replacement or maintenance. The rotating shaft 1 501 and the rotating shaft 2 502 are both rotatably mounted in the cross mounting plate 508, and can be installed and fixed on the cross mounting plate 508 without affecting the rotation of the rotating shaft 1 501 and the rotating shaft 2 502. The circumferential surface of the rotating shaft 1 501 is provided with a screening roller 503, and the circumferential surface of the rotating shaft 2 502 is provided with a crushing roller 504;

[0020] It should be noted that there are four motors 2, rotating shafts 501 and screening rollers 503, which are arranged in a horizontal array inside the upper end of the working box 1. At the same time, the feed bin 4 is located above the leftmost screening roller 503, so that after the material enters the working box 1 through the feed bin 4, the four screening rollers 503 rotate, and qualified materials will fall into the lower end of the working box 1 through the gaps between the four screening rollers 503, and larger materials will move to the right with the rotation of the screening rollers 503, thereby realizing the screening and transfer of materials.

[0021] The front ends of the rotating shaft 1 501 and the rotating shaft 2 502 are respectively connected to the rear ends of the motor 1 2 and the motor 2 3 through the cross plug block 505, and the rear ends of the rotating shaft 1 501 and the rotating shaft 2 502 are plugged with a rotating rod 506 through the cross plug block 505;

[0022] It should be noted that a cross slot matching the cross plug block 505 is provided inside the motor shaft at the rear end of motor 1 2 and motor 2 3 and inside the front end of the rotating rod 506, so that the cross plug block 505 at the front end of rotating shaft 1 501 and rotating shaft 2 502 can be smoothly plugged into the inside of the motor shaft, and the cross plug block 505 at the rear end of rotating shaft 1 501 and rotating shaft 2 502 can be smoothly plugged into the front end of the rotating rod 506. Then, when motor 1 2 and motor 2 3 are working, motor 1 2 and motor 2 3 can respectively drive rotating shaft 1 501 and rotating shaft 2 502 to rotate, and can also drive the rotating rod 506 to rotate.

[0023] The circumferential surface of the rear end of the rotating rod 506 is provided with a fan blade 507, and the dust box 6 is fixedly installed inside the rear end of the working box 1 by bolts. The rotating rod 506 is rotatably installed inside the front end of the dust box 6, and the fan blade 507 is arranged inside the dust box 6. The setting of the fan blade 507 can blow air to the rear side of the dust box 6 when the fan blade 507 is working, and then the air is introduced into the feed bin 4, so that the inside of the dust box 6 forms air circulation with the outside world, and then the dust generated when the material is screened and crushed can be collected to prevent the dust from floating randomly. In order to pollute the working environment and harm the health of the workers in the working environment, a ventilation plate is arranged at the front end of the dust collecting box 6, a dust outlet pipe 8 is arranged in the middle of the rear end of the dust collecting box 6, and a baffle 9 is arranged inside the working box 1, and the baffle 9 is arranged above the crushing roller 504, and the baffle 9 is arranged between the rightmost screening roller 503 and the left end crushing roller 504, which can block the crushed materials above the crushing roller 504, and prevent the materials from falling into the lower end of the working box 1 through the gap between the screening roller 503 and the crushing roller 504 before they are crushed;

[0024] It should be noted that the rear end of the dust outlet pipe 8 is connected to the water tank, and it directly leads to the inside of the water tank, so that the dust directly enters the water, avoiding the dust from being directly discharged to the outside to pollute the air.

[0025] The working principle and use process of the utility model are as follows: when it is necessary to screen and crush ore and other materials, first, the ore and the like are fed into the interior of the working box 1 through the feeding bin 4, and then the motor 1 2 and the motor 2 3 are started. The motor 1 2 and the motor 2 3 drive the rotating shaft 1 501 and the rotating shaft 2 502 to rotate, so that the screening roller 503 and the crushing roller 504 rotate. The rotation of the screening roller 503 can screen the materials, so that the qualified materials pass through the gap of the screening roller 503 and fall into the lower end of the working box 1, and the unqualified materials move to the right and fall on the crushing roller 504. After being crushed by the crushing roller 504 and qualified, they fall into the lower end of the working box 1, and then are discharged and collected through the discharge port.

[0026] At the same time, during the screening and crushing process, the rotation of the rotating shaft 1 501 and the rotating shaft 2 502 will also drive the rotating rod 506 to rotate, so that the rotating rod 506 drives the fan blade 507 to rotate, so that air circulation is generated inside the working box 1, and the dust generated during the screening and crushing is discharged and collected through the dust outlet pipe 8, so as to prevent the dust from directly floating in the working environment and polluting the air.

[0027] After this device has been used for a period of time, when some screening rollers 503 or crushing rollers 504 are damaged, unscrew the bolts and remove the dust box 6 from the rear end of the working box 1. At this time, the damaged screening roller 503 or crushing roller 504 can be pulled out from the rear end and replaced with a new screening roller 503 or crushing roller 504, thereby improving subsequent screening and crushing work.

[0028] 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.
