[0015] (Three) beneficial effects

[0016] The building garbage recycling device for building construction has the following beneficial effects:

[0017] 1.

Therefore, when shoveling construction waste, the fixed claw can grip it firmly without loosening, and it can be opened when dumping is required, achieving the goal of reducing the amount of manual labor required.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 7This utility model provides a technical solution: a construction waste recycling device for building construction, comprising a housing 1. A shovel 2 is fixedly connected to the side of the housing 1, and shovel walls 3 are fixedly connected to both sides of the shovel 2. A hollow rod 4 is fixedly connected to the other end of the housing 1. A handle 5 is sleeved on one end of the hollow rod 4, and a release button 6 is installed on the side of the hollow rod 4 near the handle 5. A battery is installed inside the housing 1. The housing 1 is the main connecting part of the device and the installation space for the mechanism. The shovel 2 and the shovel walls 3 on both sides constitute the part used to shovel construction waste. The hollow rod 4 and handle 5 connected to the other end of the housing 1 facilitate the operator's grip and control of the device, enabling flexible operation on the construction site. The release button 6 is a control component that contacts the fixed claw 17 and works in conjunction with the motor 7 and the solenoid valve 22. The battery inside the housing 1 provides power to the entire device, ensuring that the device can be operated by hand. A motor 7 is installed inside the outer casing 1. A motor gear 8 is fixedly connected to the motor shaft of the motor 7. A bushing gear 10 meshes with the side of the motor gear 8. The bushing gear 10 is located on the outer surface of the bushing 9. The bushing 9 has a space inside the outer casing 1 that allows it to rotate. Inside the outer casing 1, the motor 7 acts as a power source. Through the meshing of the motor gear 8 and the bushing gear 10 on the outer surface of the bushing 9, the motor 7 transmits power to the bushing 9, enabling the bushing 9 to rotate within the space inside the outer casing 1, thus driving subsequent mechanisms. A rotating shaft 12 is movably connected inside the bushing 9. A retaining strip 11 is formed on the outer surface of the rotating shaft 12, and a retaining groove is formed on the inner side of the bushing 9 to mate with the retaining strip 11. The rotating shaft 12 can move axially relative to the bushing 9 but cannot rotate. The bushing 9 and the rotating shaft 12 are connected through the engagement of the retaining strip 11 and the retaining groove. This design allows the rotating shaft 12 to move axially within the bushing 9 without relative rotation. This connection method ensures that the rotating shaft 12 can rotate with the bushing 9, while also enabling its own axial movement, providing a structural foundation for subsequent functional implementation. One end of the rotating shaft 12 is fixedly connected to a torque-limiting main gear 13, and a torque-limiting spring 14 is fixedly connected to one side of the torque-limiting main gear 13. The other end of the torque-limiting main gear 13 meshes with a torque-limiting secondary gear 15, and one end of the torque-limiting spring 14 is fixedly connected to the interior of the outer casing 1. The elasticity provided by the torque-limiting spring 14 allows the torque-limiting main gear 13 and the torque-limiting secondary gear 15 to mesh. When encountering significant resistance, the torque-limiting main gear 13 and the torque-limiting secondary gear 15 generate an axial force on the rotating shaft 12, overcoming the elastic force of the torque-limiting spring 14 and compressing it. This causes displacement of the rotating shaft 12, disengaging the torque-limiting main gear 13 and the torque-limiting secondary gear 15. This torque-limiting mechanism prevents damage to the device due to excessive torque, thus protecting the device. A pawl wheel 16 is fixedly connected to the side of the torque limiting gear 15. A fixed pawl 17 is fixedly connected to the side of the pawl wheel 16. A pawl hook 18 is fixedly connected to the inner side of the fixed pawl 17. There are two fixed pawls 17 and several pawl hooks 18. A ratchet 19 is fixedly connected to the outer surface of the pawl wheel 16.The torque-limiting gear 15 drives the pawl wheel 16 and the fixed pawl 17 to rotate. The fixed pawl 17 and several inner hooks 18 are components directly used to fix construction waste. When the pawl wheel 16 rotates, the fixed pawl 17 and hooks 18 move accordingly, realizing the function of grabbing and fixing the waste. The ratchet 19 on the outer surface of the pawl wheel 16 cooperates with the subsequent outer ratchet 20 to limit the rotation direction of the pawl wheel 16. The outer ratchet 20 is provided on the side of the pawl wheel 16. The outer ratchet 20 can mesh with the ratchet 19, so that the pawl wheel 16 can only rotate in one direction. A ratchet spring 21 is fixedly connected to the side of the outer ratchet 20. The other end of the ratchet spring 21 is fixed inside the outer casing 1. The solenoid valve 22 is located on the side of the outer ratchet 20. The solenoid valve rod 23 of the solenoid valve 22 is fixedly connected to the outer ratchet 20. The outer ratchet 20 meshes with the ratchet 19 of the pawl wheel 16 to ensure that the pawl wheel 16 can only rotate in one direction, so that the construction waste will not be released after being fixed. Ratchet spring 21 connects the outer ratchet 20 and the interior of housing 1, serving to reset and maintain the engagement state between the outer ratchet 20 and ratchet teeth 19. Solenoid valve 22 and its solenoid valve rod 23 are connected to the outer ratchet 20. By controlling the on / off state of solenoid valve 22, the position of the outer ratchet 20 can be controlled, thereby releasing the unidirectional rotation function of the control pawl wheel 16 and enabling it to rotate in the opposite direction. A pressure plate 24 is mounted on the upper surface of the shovel face 2. The pressure plate 24 contains an elastic contact blade 25 and a contact 26. The pressure plate 24 and the elastic contact blade 25 have a certain degree of elasticity, and the elastic contact blade 25 and contact 26 are electrically connected to the motor 7. The pressure plate 24 on the shovel face 2 and its internal elastic contact blade 25 and contact 26 constitute a pressure triggering device. When construction waste is placed on the shovel surface 2 and pressure is applied to the pressure plate 24, the elastic contact blade 25 and the contact head 26 will come into contact due to the elastic deformation of the pressure plate 24, thereby triggering an electrical signal. This electrical signal is electrically connected to the motor 7 and is used to control the start and rotation direction of the motor 7, realizing the automatic triggering function after the device shovels up the waste.

[0030] When the elastic contact blade 25 contacts the contact head 26, it triggers an electrical signal to make the motor rotate in the forward direction and the fixed claw 17 moves downward to achieve the action of fixing and grabbing construction waste. When the button 6 is released, it triggers its own electrical signal on the one hand and intercepts the signal of the contact head 26 on the other hand, causing the solenoid valve 22 to start and retract the outer ratchet 20, no longer engaging with the ratchet 19, releasing the one-way locking of the claw wheel 16. At the same time, the motor rotates in the reverse direction and the fixed claw 17 moves upward. The fixed claw 17 releases the construction waste, which can then fall to the collection point such as the truck bed.

[0031] In summary, this construction waste recycling device, through the arrangement of the claw wheel 16, fixed claw 17, and claw hook 18, enables it to fix construction waste inside the shovel. The claw hook 18 can grip uneven objects, increasing the fixing strength. Through the coordinated arrangement of the bushing 9, rotating shaft 12, torsion-limiting main gear 13, torsion-limiting spring 14, and torsion-limiting secondary gear 15, the rotating shaft 12 is allowed to move axially within the bushing 9 during use. When fixing or moving to its limit position, the trapezoidal design of the teeth of the torsion-limiting main gear 13 and torsion-limiting secondary gear 15 generates an axial force that overcomes the torsion-limiting spring 14, causing the rotating shaft 12 to move axially. The torsion-limiting main gear 13 and torsion-limiting secondary gear 15 disengage, preventing damage to the structure. Simultaneously, it allows the two fixed claws 17 to move asynchronously. This construction waste recycling device, through the arrangement of ratchet 19, outer ratchet 20, and ratchet spring 21, effectively restricts the unidirectional rotation of the pawl wheel 16. Through the coordinated arrangement of the outer ratchet 20, ratchet spring 21, solenoid valve 22, and solenoid valve rod 23, during operation, when the fixed pawl 17 moves downwards, the triangular tooth design of the ratchet 19 and outer ratchet 20 overcomes the force of the ratchet spring 21, causing the ratchet 19 and outer ratchet 20 to disengage from the pawl wheel. 16 can rotate. When the fixed claw 17 is only subjected to an upward force and the button 6 is not pressed, the ratchet spring 21 will reset the outer ratchet 20, causing it to lock the claw 16 and prevent it from rotating. When the button 6 is pressed, the solenoid valve 22 pulls the outer ratchet 20 downward through the solenoid valve rod 23, so that the ratchet 19 and the outer ratchet 20 are no longer engaged, and 16 can rotate freely. Thus, when shoveling construction waste, it can be gripped by the fixed claw 17 and will not loosen. It can be opened when it needs to be dumped, thus achieving the purpose of reducing the amount of work required by workers.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
