Furthermore, the power device can drive the roller to rotate, and the contact between the roller and the concrete block drives the concrete block to translate on the bottom plate, thereby changing the hammering position of the hammer head on the concrete block. The rotation of the roller driven by the power device can make the concrete block translate on the bottom plate, thereby changing the hammering position of the hammer head, making the crushing process more uniform and improving the crushing quality; The present invention adopts a rotating hammer head for hammer crushing, which can effectively crush the concrete blocks into small pieces and remove the steel bars therein. It is suitable for crushing reinforced concrete blocks of different sizes and shapes, has strong adaptability, is suitable for various construction waste treatment scenarios, and is convenient for recycling concrete and steel bars.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0018] like Figure 1-Figure 6 As shown, a concrete crushing and recycling device proposed by the present invention includes a base plate 1 and a motor 11. A main board 12 is provided on one side of the upper surface of the base plate 1. A main shaft 19 is rotatably provided on the upper end of the main board 12. A hammer head 15 is provided at one end of the main shaft 19 through a shaft rod 14. A shaft head 18 is provided at the other end of the main shaft 19.

[0019] Based on Example 1: During the use of the concrete crushing and recycling device of the present invention, a large concrete block containing steel bars can be placed on the bottom plate 1, and then an external power supply is connected to make the device work, and the push plate 6 is driven by the push assembly to slide against the concrete block on the bottom plate 1 to a specified position; Then the motor 11 works to drive the square head 21 to rotate, the square head 21 drives the main shaft 19 to rotate through the shaft head 18, the main shaft 19 drives the hammer head 15 to rotate through the shaft rod 14, when the hammer head 15 rotates to a certain height, the motor 11 stops working, then the upper cylinder 16 works, thereby driving the motor 11 to move through the connecting rod 17, at this time the motor 11 drives the slider 22 to slide in the slide groove 23, so that the square head 21 is separated from the shaft head 18, at this time the hammer head 15 falls along the circular trajectory under the action of gravity until the hammer head 15 hits the concrete block, breaking the concrete block into small pieces by hammering and removing the steel bars therein; The brake assembly is controlled to work. When a single hammering is completed, the main shaft 19 is quickly braked to prevent the hammer head 15 from swinging under the action of inertia. After the hammer head 15 is kept in a vertical state under the cooperation of the brake assembly, the square head 21 is reinserted into the shaft head 18 through the operation of the sliding assembly to complete the preparation action for the next hammering; Furthermore, the power device can drive the roller shaft 7 to rotate, and the contact between the roller shaft 7 and the concrete block drives the concrete block to translate on the bottom plate 1, thereby changing the hammering position of the hammer head 15 on the concrete block. Example 2

[0020] like Figure 1-Figure 6 As shown in the figure, a concrete crushing and recycling device proposed by the present invention, compared with the first embodiment, this embodiment also includes: the sliding assembly is composed of a support leg 9, a cross plate 10, an upper cylinder 16, a connecting rod 17, a slider 22 and a slide groove 23, the cross plate 10 is arranged at the upper end of the main plate 12, one end of the support leg 9 is arranged on the cross plate 10, the other end of the support leg 9 is arranged on the bottom plate 1, the slide groove 23 is opened on the upper surface of the cross plate 10, the slider 22 is arranged on the outer wall of the motor 11, the slider 22 is slidably arranged in the slide groove 23, the upper cylinder 16 is arranged on the lower surface of the cross plate 10, one end of the connecting rod 17 is arranged at the output end of the upper cylinder 16, and the other end of the connecting rod 17 is arranged on the outer wall of the motor 11, the upper cylinder 16 works, thereby driving the motor 11 to move through the connecting rod 17, and at this time the motor 11 drives the slider 22 to slide in the slide groove 23.

[0021] The brake stop assembly consists of an electromagnetic ring 13, a brake pad 24, a slide rod 25, a spring 26, an iron seat 27 and a main ring 28. The main ring 28 is arranged on the main board 12, and the main shaft 19 passes through the central axis of the main ring 28. The electromagnetic ring 13 is arranged on the outside of the main ring 28, the slide rod 25 is slidably arranged on the main ring 28, the brake pad 24 is arranged at the bottom end of the slide rod 25, the iron seat 27 is arranged at the top end of the slide rod 25, and the spring 26 is sleeved on the slide rod 25. When the electromagnetic ring 13 is energized, the iron seat 27 is adsorbed by the action of magnetic attraction. At this time, the brake pad 24 is away from the main shaft 19, and the spring 26 is compressed to produce deformation. When the electromagnetic ring 13 is de-energized, the brake pad 24 is squeezed against the outer wall of the main shaft 19 under the action of the elastic force of the spring 26.

[0022] The spring 26 is located between the inner wall of the main ring 28 and the outer wall of the brake pad 24. The original length of the spring 26 is greater than the distance between the main ring 28 and the main shaft 19. The design of the spring 26 being located between the inner wall of the main ring 28 and the outer wall of the brake pad 24 ensures that the spring 26 has sufficient elastic force to push the brake pad 24 close to the main shaft 19, thereby achieving fast and accurate braking. Due to the elastic force of the spring 26, when the electromagnetic ring 13 is powered off, the brake pad 24 can quickly rest on the main shaft 19 to achieve fast braking of the hammer head 15, reducing the swinging time of the hammer head 15 caused by inertia. The original length of the spring 26 is greater than the distance between the main ring 28 and the main shaft 19, ensuring that the spring 26 is always in a pre-compression state, thereby providing a stable braking force and ensuring the reliability of equipment operation.

[0023] A square opening 8 is provided on the bottom plate 1, and a roller shaft 7 is rotatably arranged in the square opening 8, and the upper end of the roller shaft 7 is flush with the upper surface of the bottom plate 1. The power device can drive the roller shaft 7 to rotate, and the contact between the roller shaft 7 and the concrete block drives the concrete block to translate on the bottom plate 1.

[0024] A screw rod 20 is installed on the hammer head 15, and the thread of the screw rod 20 is arranged at the bottom end of the shaft rod 14. Through the cooperation of the above structure, the screw rod 20 installed on the hammer head 15 cooperates with the thread of the bottom end of the shaft rod 14, so that the disassembly and replacement process of the hammer head 15 becomes simpler. When the hammer head 15 is worn or damaged, the operator can quickly disassemble it through the screw rod 20, replace or repair it, thereby reducing the downtime of the equipment.

[0025] A support base 2 is disposed on the lower surface of the base plate 1 . There are four support bases 2 in total, and the positions of the four support bases 2 are distributed in a rectangular array on the lower surface of the base plate 1 .
