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.

[0022] Example:

[0023] See also Figure 1-4 , a crusher for recycled rubber production which is easy to clean and maintain, comprises a support platform 1 and two groups of half-crushing box frames 2 symmetrically slidably fitted on the support platform 1, the two groups of half-crushing box frames 2 are rotatably connected with crushing rollers 3, a feeding chute 10 adapted to the two groups of half-crushing box frames 2 is provided in the middle position of the support platform 1, a crushing driving mechanism for driving the crushing rollers 3 on the same side to rotate is provided on the outside of each group of half-crushing box frames 2, a locking mechanism is provided between the two groups of half-crushing box frames 2, a crushing guide mechanism adapted to the crushing roller 3 is provided on the inner side wall of each group of half-crushing box frames 2, and a confluence mechanism is provided above the two groups of half-crushing box frames 2, the two half-crushing box frames 2 can be separated to both sides by the support platform 1 and the two groups of half-crushing box frames 2 rotatably connected with the crushing rollers 3, so as to facilitate the two crushing rollers 3 to be moved between the two separated crushing rollers 3. The pulverizing rollers 3 are driven by the pulverizing drive mechanisms on their respective sides to rotate, so that the two pulverizing rollers 3 cooperate to complete the pulverization of the scraps. The pulverizing guide mechanism is convenient for cooperating with the pulverizing rollers 3 to pulverize the scraps. The confluence mechanism is convenient for collecting the scraps put onto the two pulverizing rollers 3, so that timely adding materials for pulverization is convenient. The pulverizer for recycled rubber production, which is easy to clean and maintain, is convenient for separating the two pulverizing rollers 3, so that the two pulverizing rollers 3 can be cleaned and maintained from the gap between the two pulverizing rollers 3, so as to avoid the problem that the sticky rubber adheres to the pulverizing rollers and causes hardening after standing, which is easy to affect the subsequent pulverization operation, thereby ensuring a certain pulverization effect.

[0024] The crushing drive mechanism includes a crushing motor 8 fixedly mounted on the semi-crushing box frame 2. The output end of the crushing motor 8 is connected to the crushing roller 3 on the same side through a sprocket chain 9. When the crushing motor 8 is started, the crushing roller 3 on the same side is driven to rotate through the transmission cooperation of the sprocket chain 9.

[0025] Both ends of the crushing roller 3 are rotatably connected to the semi-crushing box frame 2 through a rotating seat 4. The arrangement of the two rotating seats 4 increases the rotation stability of the crushing roller 3 and further ensures the crushing effect.

[0026] The crushing and guiding mechanism includes a plurality of guide baffles 5 which are fixedly installed at intervals on the inner wall of the semi-crushing box frame 2 and adapted to the crushing roller 3 on the same side. The top and bottom of the guide baffles 5 have a certain inclination slope toward the crushing roller 3. The arrangement of the plurality of guide baffles 5 and the inclination slopes of the top and bottom facilitates the crushing and cleaning and maintenance of the crushing roller 3.

[0027] The confluence mechanism includes a semi-confluence cover 12 fixedly mounted on the top of the semi-crushing box frame 2. Two semi-confluence covers 12 arranged on two groups of semi-crushing box frames 2 can be combined to form a guide cover, so that the scraps can be conveniently concentrated and introduced into the middle of the two semi-crushing box frames 2.

[0028] The locking mechanism includes a fixed seat 13 with an arc-shaped slot 14 on the top and a rotating clip strip 16 fixedly connected to a clip rod that slidably cooperates with the arc-shaped slot 14. The fixed seat 13 is fixedly connected to one of the half-crushing box frames 2, and the rotating clip strip 16 is rotatably connected to the other half-crushing box frame 2 through a rotating shaft 15. By rotating the rotating clip strip 16, the clip rod can be driven to slide out of the arc-shaped slot 14, so that the two half-crushing box frames 2 can be moved to both sides. After the two half-crushing box frames 2 are merged in the middle, the clip rod can be slid into the arc-shaped slot 14 by rotating the rotating clip strip 16, so that the two half-crushing box frames 2 can be tightened.

[0029] The support platform 1 is located on both sides of the material drop chute 10 and is provided with slide rails 6 compatible with the two half-crushing box frames 2, and the crushing motor 8 is fixedly connected to the half-crushing box frame 2 through a slide plate 7 that slides with the support platform 1. A plurality of support legs 11 are fixedly installed at the bottom of the support platform 1. The slide rails 6 can be used to guide the half-crushing box frame 2 horizontally. The crushing motor 8 can be used to transfer the gravity of the crushing motor 8 to the support platform 1, thereby reducing the pressure on the half-crushing box frame 2 and improving the stability of the overall device. The setting of a plurality of support legs 11 makes it convenient to raise the position of the material drop chute 10 so that the crushed material can be received from the bottom of the material drop chute 10.

[0030] When in use, the scraps are placed from above into the space formed by the two half-crushing box frames 2, and the crushing drive mechanisms on both sides are driven. The crushing drive mechanisms on both sides drive the crushing rollers 3 on their respective sides to rotate, thereby cooperating with the crushing guide mechanisms on their respective sides to crush and stir the scraps. The two crushing rollers 3 rotate to both sides at the same time to divert the scrap powder. While diverting, the scrap waste can be pulled and a certain crushing effect is achieved. The crushed scraps fall out through the drop chute 10. After the crushing is completed, the locking mechanism is released and the two half-crushing box frames 2 are pulled to both sides, so that the two crushing rollers 3 can be cleaned and maintained in the middle position. After the cleaning and maintenance are completed, the two half-crushing box frames 2 are merged to the middle and locked by the locking mechanism to prepare for the next crushing operation.
