DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] Reference Figures 1-4As shown in the figure, a multi-stage composite crusher includes a first crushing box 1 and a second crushing box 2 located below the first crushing box 1 and communicating with the inside of the first crushing box 1. It also includes two groups of rotating rods 318 and two groups of second crushing rollers 319 that are parallelly distributed inside the second crushing box 2. Sliding grooves 317 are provided on the left and right side walls of the second crushing box 2. A sliding block 316 is slidably connected inside the sliding groove 317. The two groups of rotating rods 318 are respectively rotatably connected between the sliding blocks 316 on the left and right sides. The second crushing roller 319 is fixed to the outer wall of the rotating rod 318. A second motor 315 is installed on the outer wall of any one group of sliding blocks 316. The output end of the second motor 315 is connected to the rotating rod 318. When the second motor 315 is turned on, it can drive the rotating rod 318 and the second crushing roller 319 to rotate towards each other. After the material falls between the two groups of second crushing rollers 319, it can be comprehensively crushed. Under the action of the sliding block 316 and the sliding groove 317, the distance between the two groups of second crushing rollers 319 can be adjusted. When the distance between the two groups of second crushing rollers 319 increases, large-volume materials can be used for crushing work; when the distance between the two groups of second crushing rollers 319 decreases, small-volume materials can be crushed, which can enhance the scope of use of the equipment and meet the working requirements.

[0028] On the outer walls of the left and right sides of the second crushing box 2, vertically distributed slots 413 are provided. A movable block 414 is slidably connected to the inner wall of the slot 413. A connecting plate 411 is fixed to the bottom end of the sliding block 316. The connecting plate 411 and the outer wall of the movable block 414 are hinged by a hinge rod 412. By moving the movable block 414 up and down inside the slot 413, the two hinge rods 412 can be controlled to rotate towards or away from each other, and at the same time drive the two second crushing rollers 319 to move towards or away from each other. This control method is more stable, and the moving distances of the two second crushing rollers 319 can be the same, so as to stably control the distance between the two second crushing rollers 319. A spring 415 is arranged inside the slot 413. One end of the spring 415 is connected to the movable block 414, and the other end is connected to the inner wall of the slot 413. The spring 415 can play a good elastic effect. In the initial state, the spring 415 can be in a compressed state. Without applying external force, the spring 415 can drive the movable block 414 to rise to achieve a stable moving effect. A contact rod 416 is fixed to the bottom end of the movable block 414. A movable plate 417 corresponding to the contact rod 416 is slidably connected to the side wall of the second crushing box 2. One side of the bottom end of the contact rod 416 is set to be arc-shaped, and an inclined surface matching the arc shape is arranged on the top of the movable plate 417. After horizontally moving the movable plate 417, the inclined surface can be in contact with the bottom arc of the contact rod 416 and push the contact rod 416 and the movable block 414 to rise, so that the spring 415 stretches and the stability effect is improved. A hydraulic rod 418 is installed on the side wall of the second crushing box 2. The output end of the hydraulic rod 418 is connected to the movable plate 417. By turning on the hydraulic rod 418, the movable plate 417 can be driven to move horizontally back and forth, so as to control the contact rod 416 and the movable block 414 to move up and down reciprocally. This method can also lock the height of the movable block 414, so as to ensure that the distance between the two second crushing rollers 319 can be stably controlled.

[0029] The first crushing box 1 includes a first motor 311, a first crushing roller 312 and a rotating gear 313. Two first crushing rollers 312 are provided and are parallelly distributed on the inner wall of the first crushing box 1. Rotating gears 313 that mesh with each other are fixed to the left ends of the two first crushing rollers 312. The first motor 311 is installed at the right end of the first crushing box 1 and the output end is connected to any one of the first crushing rollers 312. By turning on the first motor 311, the first crushing roller 312 and the rotating gear 313 can be driven to rotate. The rotation of any one of the rotating gears 313 can drive the other rotating gear 313 to rotate towards each other, so that the two first crushing rollers 312 rotate towards each other to achieve a preliminary crushing effect. Two protective plates 314 distributed front and back are fixed to the top end of the first crushing box 1. The two protective plates 314 are inclined from top to bottom. The protective plates 314 are arranged to facilitate guiding the material to fall into the first crushing box 1. At the same time, when the material is crushed, it is easy to splash, and the protective plates 314 can provide protection to improve the use safety of the equipment.

[0030] Working principle: When it is needed, pour the material into the first crushing box 1, and guide it through the protective plate 314 to make it completely enter the first crushing box 1, turn on the first motor 311 to drive the first crushing roller 312 and the rotating gear 313 to rotate, so that the two sets of first crushing rollers 312 rotate towards each other, which can perform preliminary crushing on the material; under the action of gravity, the material continues to be fed, and turn on the second motor 315 to drive the rotating rod 318 and the second crushing roller 319 to rotate for crushing again.

[0031] When it is necessary to adjust the distance between the two sets of second crushing rollers 319, the movable plate 417 is driven to move backward by opening the hydraulic rod 418. At this time, the inclined surface at the top of the movable plate 417 can interfere with the arc-shaped bottom of the interference rod 416, so that the interference rod 416 rises. At this time, the movable block 414 can slide on the inner wall of the groove 413 and drive the spring 415 to stretch. The movable block 414 rises and drives the two sets of hinged rods 412 to rotate separately, and pushes the two sets of sliding blocks 316, the two sets of rotating rods 318 and the two sets of second crushing rollers 319 to move away from each other, thereby increasing the distance between the second crushing rollers 319, which is convenient for crushing large-volume materials.

[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.
