Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 5 The utility model provides a concrete raw material crushing device, comprising a machine body 1, a feed inlet 2, the feed inlet 2 is fixedly installed on the top of the machine body 1, and two driving motors 5 are fixedly installed on one side of the machine body 1. One end of the output shaft of each driving motor 5 is fixedly connected to a transmission rod 4, and both ends of the transmission rod 4 are rotatably connected to the inner wall of the machine body 1. The outer wall of each transmission rod 4 is fixedly connected to a crushing tooth 3, and a plurality of crushing teeth 3 are arranged in an array inside the machine body 1 through the transmission rod 4.

Limiting grooves 16 are provided on the other two sides of the machine body 1, and a connecting rod 10 is sleeved inside each limiting groove 16, and one end of each connecting rod 10 is rotatably connected to the inner wall of one side of the movable plate 7. The other end of each connecting rod 10 is rotatably connected to a large gear 11, and one side of each large gear 11 is meshed with a small gear 13. The second transmission rod 14 is fixedly connected inside the two pinions 13, and the middle part of the second transmission rod 14 is rotatably connected to the inner wall of the body 1. A servo motor 15 is fixedly connected to one side of the body 1, and one end of the output shaft of the servo motor 15 is fixedly connected to the second transmission rod 14.

[0027] During operation, the machine body 1 is moved to the work site and connected to the power supply, and then the two driving motors 5 are controlled to start, and the output shafts of the two driving motors 5 are used to drive the two transmission rods 4 to rotate, so that the multiple crushing teeth 3 rotate inside the machine body 1. Then the concrete raw material is poured between the multiple crushing teeth 3 from the feed port 2, and the crushing work of the concrete raw material is completed by the rotation of the crushing teeth 3, and the crushed raw material falls on the surface of the screen 8. The movable plate 7 is used to ensure the stability of the screen 8, and then the servo motor 15 is started, and the output shaft of the servo motor 15 is used to drive the second transmission rod 14 to rotate, and the connection between the two ends of the second transmission rod 14 and the inside of the machine body 1 is used to prevent the second transmission rod 14 from being misaligned when rotating. Each pinion 13 can stably mesh with the large gear 11, and the large gear 11 is driven to rotate by the rotation of the pinion 13. Then, the rotation of the large gear 11 can involve the connecting rod 10 to move inside the limit groove 16, and then the connecting rod 10 is connected to the movable plate 7 by rotation, so that the large gear 11 can drive the movable plate 7 to move inside the machine body 1 when rotating. The concrete raw materials accumulated on the surface of the screen 8 can be screened by utilizing the force generated when the movable plate 7 moves. With the above-mentioned method, when the movable plate 7 cannot move and the screening efficiency of the screen 8 is reduced, the staff can quickly repair or replace the equipment, thus reducing the time consumed for repair or replacement and improving the crushing efficiency of the concrete raw materials.

[0028] Further, such as Figure 2 As shown, a positioning rod 12 is rotatably connected to the middle of each large gear 11 , one end of each positioning rod 12 is fixedly connected to the machine body 1 , and each large gear 11 is arranged on one side of the machine body 1 via the positioning rod 12 .

[0030] Further, such as Figure 4 As shown, the three inner side walls of the machine body 1 are fixedly connected with inclined plates 18, and a conveyor belt 19 is arranged on one side of the bottom of the inclined plate 18, and the conveyor belt 19 is rotatably connected with the inner part of the machine body 1. Two limit plates 20 are fixedly connected to one side of the machine body 1, and a recovery box 21 is arranged between the two limit plates 20, and one side of the recovery box 21 is in contact with one side of the machine body 1.

[0031] During operation, the screened concrete raw materials can stably slide onto the surface of the conveyor belt 19 through the inclined plate 18, and then the conveyor belt 19 is started to rotate to bring these screened concrete raw materials out of the machine body 1. The limiting plate 20 allows the worker to quickly place the recovery box 21 under one end of the movable plate 7, and then the larger opening groove 6 opened on one side of the machine body 1 allows the raw material particles that cannot pass through the screen 8 to slide into the interior of the recovery box 21, so that the staff can uniformly collect and process these raw materials, so that the raw material particles can stably enter the interior of the recovery box 21, thereby improving the use efficiency of the device.

[0032] Further, such as Figure 5 As shown, both sides of the movable plate 7 are provided with slide grooves 9, and two positioning blocks 17 are sleeved inside each slide groove 9. One side of each positioning block 17 is fixedly connected to the body 1, and both sides of the movable plate 7 slide inside the body 1 through multiple positioning blocks 17.

[0033] During operation, when the movable plate 7 is moved by the connecting rod 10, the sliding grooves 9 on both sides of the movable plate 7 are engaged with the screen 8, so that the movable plate 7 can move stably inside the machine body 1 to prevent the movable plate 7 from being misplaced during the movement, thereby improving the stability of the movable plate 7, improving the screening effect of the screen 8, and improving the practicability of the device.

[0034] Working principle: After the machine body 1 is moved to the work site and connected to the power supply, the two driving motors 5 are controlled to start, and the output shafts of the two driving motors 5 are used to drive the two transmission rods 4 to rotate, so that the multiple crushing teeth 3 rotate inside the machine body 1. Then the concrete raw materials are poured between the multiple crushing teeth 3 from the feeding port 2, and the crushing work of the concrete raw materials is completed by the rotation of the crushing teeth 3, and the crushed raw materials fall on the surface of the screen 8. Then the servo motor 15 is started, and the output shaft of the servo motor 15 is used to drive the second transmission rod 14 to rotate, and the rotation of the small gear 13 is used to drive the large gear 11 to rotate. When the large gear 11 rotates, it can drive the movable plate 7 to move inside the machine body 1, and the engagement of the slide grooves 9 on both sides of the movable plate 7 with the screen 8 can prevent the movable plate 7 from being misaligned during the movement. The concrete raw materials accumulated on the surface of the screen 8 can be screened by the force generated when the movable plate 7 moves. The screened concrete raw materials can stably slide onto the surface of the conveyor belt 19 through the inclined plate 18, and then the conveyor belt 19 is started to rotate to bring the screened concrete raw materials out of the machine body 1. The larger opening groove 6 opened on one side of the machine body 1 allows the raw material particles that cannot pass through the screen 8 to slide into the inside of the recovery box 21, thereby completing the crushing of the concrete raw materials.
