Description

Technical Field

[0001] This utility model relates to the field of mixing machinery technology, and in particular to a mixing equipment for plastic mat raw materials. Background Technology

[0002] The surface layer of permeable synthetic running tracks is typically made of colored ethylene propylene diene monomer (EPDM) rubber granules mixed with polyurethane adhesive. During construction, the raw materials need to be evenly mixed on-site using mixing equipment before being laid out. Existing small-scale EPDM granule mixing equipment usually consists of a wheeled frame and a mixing device mounted on the frame. Its compact structure and easy mobility meet the portability requirements for construction in small areas such as kindergartens and community activity squares.

[0003] In practice, to improve efficiency, workers often use the "mixing equipment moving and unloading method," which involves pushing the equipment along the construction area while simultaneously opening the unloading port to allow the mixture to fall directly to the ground, avoiding the intermediate transfer process of "mixing → loading into barrels → handling → dumping." While this operating mode saves material transfer time, it exposes deficiencies in the power cord management mechanism of existing equipment. Current equipment treats the power cord as an "external independent accessory" separate from the main body of the equipment, lacking integrated storage and follow-up design, leading to the following technical problems: Firstly, labor costs increase significantly. The equipment relies on an external power cord for operation. When workers push the equipment to move and unload materials, a dedicated worker must accompany the equipment throughout the process to lift, straighten, and retract the power cord, preventing it from getting tangled in the equipment wheels, snag on ground obstacles, or being crushed. This results in at least one additional worker being added to the cost of each piece of equipment per operation. Secondly, the power cord lacks a dedicated storage carrier and is usually haphazardly wrapped around the vehicle frame during transportation, leading to wear on the outer sheath and loose connections, posing significant safety hazards. Therefore, it is necessary to design a plastic mat raw material mixing equipment that can retract and coordinate the power cord during operation. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a plastic mat raw material mixing device, which solves the defect that the power cord cannot move with the material when using the "moving pouring method" for construction, and also solves the problem of integrated storage of the power cord.

[0005] The technical solution of this utility model is as follows: A plastic mat raw material mixing device includes a frame supported by four wheels, a mixing tank on the frame, a mixing rod inside the mixing tank, the bottom end of the mixing rod being connected to the output shaft of a motor via a coupling, the motor being located below the mixing tank, and a winding device installed between the wheels of the frame and the mixing tank, the mounting base of the winding device being connected to the frame via a manual screw jack. In the winding device, the driving gear and the first pulley are coaxially mounted on the driving shaft. The driving shaft passes through the first pulley and extends outward to the outside of the frame, with a crank handle connected to its end. The driving gear meshes with the driven gear on the winding shaft. A second pulley is mounted on the axle of the traveling wheel, and the second pulley is connected to the first pulley via a belt. By setting the transmission ratio between the first pulley and the second pulley, as well as the gear ratio between the driving gear and the driven gear, the linear speed of the winding device releasing the wire is greater than or equal to the circumferential linear speed of the traveling wheel.

[0006] The height of the winding device is raised by a manual screw jack, which keeps the belts of the first and second pulleys taut. The rotating wheels drive the winding device to wind and unwind the cable via belt transmission. In scenarios where the equipment is stationary or needs to wind up the cable when changing direction, the height of the winding device is lowered by a manual screw jack, the belts loosen and disengage from the transmission, and the cable can be manually wound and unwound by cranking a handle, enhancing operational flexibility.

[0007] Furthermore, the mixing tank is provided with a discharge port at the bottom, and a discharge hopper is provided below the discharge port. The discharge hopper is detachable. The structure is installed at the front end of the frame. The detachable structure includes an arc-shaped hook located on the rear side of the unloading hopper. The frame has a matching slot at the corresponding position. The detachable structure facilitates cleaning of residual materials after unloading and improves the convenience of equipment maintenance.

[0008] Furthermore, the frame is a frame formed by connecting multiple longitudinal and transverse rods. The bottom of the frame is provided with four wheel mounting posts that extend outwards. The main body of the frame is provided with transverse mounting beams. One end of the mounting beam is detachably connected to the frame by bolts, and the other end forms a belt avoidance hollow area with the frame.

[0009] Furthermore, an axle is provided at the lower part of the wheel mounting post, a travel wheel is installed on the outer side of one of the axles, and a second pulley is coaxially fitted on the inner side of the axle. The travel wheel and the second pulley are symmetrically distributed on both sides of the wheel mounting post.

[0010] Furthermore, the mounting beam is equipped with the manual screw jack, and the output end of the manual screw jack is connected to the mounting base of the winding device.

[0011] Furthermore, the winding device and the manual screw jack are arranged at the rear of the vehicle frame, and the operating handle of the manual screw jack extends to the outside of the vehicle frame for easy operation by the worker.

[0012] The beneficial effects of this utility model are as follows: This invention utilizes a transmission system formed by the second pulley on the axle of the traveling wheel, the first pulley of the winding device, and a gear set. The rotation of the traveling wheel drives the winding device to release the wire. By setting the transmission ratio and gear ratio, the wire release speed is ensured to match the equipment's travel speed, enabling automatic wire release as the equipment moves. No dedicated personnel are required to operate this system, reducing labor costs. 2. This invention also features a quick-release structure with an arc-shaped hook and frame slot at the rear of the unloading hopper, facilitating the cleaning of residual materials after unloading and improving equipment maintenance convenience.

[0013] 3. This utility model supports manual winding and unwinding of the wire by using a crank handle at the end of the drive shaft. In scenarios where the equipment is stationary or the direction of travel of the equipment needs to be changed and the wire needs to be wound up, the height of the winding device can be adjusted by adjusting the manual screw jack, thereby adjusting the tension or slack of the belt between the first pulley and the second pulley, realizing the switching between automatic winding and unwinding and manual winding and unwinding modes, and enhancing operational flexibility.

A winding device 6 is installed between the wheels 2 of the frame 1 and the mixing tank 3. The mounting seat of the winding device 6 is connected to the frame 1 through a manual screw jack 7. In the winding device 6, the driving gear 6-1 and the first pulley 6-2 are coaxially mounted on the driving shaft. The driving shaft passes through the first pulley 6-2 and extends outward to the outside of the frame 1, with a crank 6-3 connected at the end. The driving gear 6-1 meshes with the driven gear 6-4 on the winding shaft for transmission. A second pulley 6-5 is mounted on the axle of the traveling wheel 2. The second pulley 6-5 is connected to the first pulley 6-2 through a belt 6-6. By setting the transmission ratio between the first pulley 6-2 and the second pulley 6-5 and the gear ratio between the driving gear 6-1 and the driven gear 6-4, the linear speed of the winding device 6 unwinding the wire is greater than or equal to the circumferential linear speed of the traveling wheel 2. The height of the winding device 6 is raised by the manual screw jack 7, so that the belt 6-6 between the first pulley 6-2 and the second pulley 6-5 is in a taut state. The rotation of the traveling wheel 2 drives the winding device 6 to wind and unwind accordingly through the belt 6-6. In the case of use where the equipment is stationary or the equipment changes direction and needs to wind up the cable, the height of the winding device 6 is lowered by the manual screw jack 7, the belt 6-6 is loosened and disengaged from the transmission state, and the manual winding and unwinding mode of the cable is achieved by shaking the crank 6-3, which enhances the flexibility of operation. Furthermore, the bottom of the mixing tank 3 is provided with a discharge port, and below the discharge port is a discharge hopper 8. The discharge hopper 8 is installed at the front end of the frame 1 through a detachable structure. The detachable structure includes an arc-shaped hook 8-1 set on the rear side of the discharge hopper 8. The frame 1 is provided with a matching slot 1-1 at the corresponding position. The detachable structure facilitates the cleaning of residual materials after unloading and improves the convenience of equipment maintenance. Furthermore, the frame 1 is a frame formed by multiple longitudinal and transverse rods connected to each other. At the bottom of the frame, there are four wheel mounting posts 1-2 extending outward. Inside the main body of the frame, there are transverse mounting beams 1-3. One end of the mounting beam 1-3 is detachably connected to the frame by bolts, and the other end forms a belt avoidance hollow area between the beam and the frame. Furthermore, an axle is inserted through the lower part of the wheel mounting post 1-2, and a traveling wheel 2 is installed on the outer side of one of the axles. A second pulley 6-5 is coaxially fitted on the inner side of the axle. The traveling wheel 2 and the second pulley 6-5 are symmetrically distributed on both sides of the wheel mounting post 1-2. Furthermore, a manual screw jack 7 is provided on the mounting beam 1-3, and the output end of the manual screw jack 7 is connected to the mounting base of the winding device 6. Furthermore, the winding device 6 and the manual screw jack 7 are arranged at the rear of the frame 1, and the operating handle 7-1 of the manual screw jack 7 extends to the outside of the frame 1 for easy operation by workers. 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.
