Description

Technical Field

[0001] This utility model belongs to the field of heavy-duty floor emery spreading technology, specifically, it relates to a heavy-duty floor emery spreading device. Background Technology

[0002] The background technology of heavy-duty flooring corundum spreading devices mainly involves ground hardening and wear-resistant treatment. Corundum spreading devices are used to spread corundum or other hardeners on concrete surfaces to enhance the hardness and wear resistance of the ground. They are widely used in the construction of industrial plants, warehouses, workshops, parking lots, and other flooring applications. The corundum spreading device works by spreading corundum onto the concrete surface, allowing it to react naturally over a period of time or be mechanically compacted, forming a strong adhesion layer between the corundum and the concrete surface, thereby improving the wear resistance of the ground. Modern heavy-duty flooring corundum spreading devices are usually automated, capable of automatically adjusting the spreading amount and speed as needed, improving work efficiency and construction quality. These devices are generally suitable for environments with heavy loads and high friction; therefore, their design not only requires high-quality corundum, but also that the strength and stability of the spreading device meet certain standards to adapt to complex industrial environments. Corundum spreading devices can work on concrete layers of varying thicknesses and are unaffected by environmental factors such as weather and temperature, ensuring the stability of construction quality.

[0003] The existing heavy-duty floor construction has technical problems such as uneven application of corundum and difficulty in controlling the thickness, making it difficult to ensure the consistency of the floor surface hardness and the stability of the construction quality. Utility Model Content

[0004] In view of this, the present invention provides a heavy-duty floor emery spreading device, which can solve the technical problems of uneven spreading and difficulty in controlling the thickness of emery in the construction of existing heavy-duty floors.

[0005] This utility model is implemented as follows: This utility model provides a heavy-duty floor emery spreading device, comprising a frame, an adjustable height hopper, a spiral distributing mechanism, a guide plate, and a rotatable spreading disc. The frame is a rectangular frame structure, with the adjustable height hopper at its top for storing raw materials. The bottom of the adjustable height hopper is connected to the rotatable spreading disc, and the surface of the rotatable spreading disc is configured with multiple radially distributed guide grooves. The spiral distributing mechanism is connected to the lower interior of the adjustable height hopper, and the guide plate is disposed between the spiral distributing mechanism and the rotatable spreading disc. The spreading holes evenly distributed on the guide plate are used to achieve precise dispensing of emery.

[0006] Based on the above technical solution, the heavy-duty concrete abrasive spreading device of this utility model can be further improved as follows: The spiral material distribution mechanism includes a V-shaped rotating chamber, a screw, and an external drive rotating assembly. The top of the V-shaped rotating chamber is connected to the bottom of the adjustable height hopper. The screw is installed at the center of the V-shaped rotating chamber. The outer wall of the V-shaped rotating chamber is engaged with the external drive rotating assembly. The external drive rotating assembly is used to drive the V-shaped rotating chamber to rotate, thereby changing the distance between the inner wall of the V-shaped rotating chamber and the screw to achieve uniform material distribution.

[0007] Furthermore, a driven gear is provided on the outer wall of the V-shaped rotating chamber, one side of which meshes with the driving gear. The center of the driving gear is connected to a rotary motor, which drives the driving gear to rotate, thereby driving the V-shaped rotating chamber to rotate.

[0008] Furthermore, the guide plate is made of galvanized sheet and is set at an angle of 25-45° to the horizontal, with a length of 600 mm.

[0009] Furthermore, the spray holes are φ8 mm in size and arranged in a quincunx pattern.

[0010] Furthermore, a chrome-plated ball bearing guide rail is provided on one side of the bottom of the adjustable height hopper to drive the adjustable height hopper to adjust its height.

[0011] Furthermore, the dispensing hole is a stepped hole with an upper diameter of φ9 mm and a lower diameter of φ7 mm, forming a Venturi effect and reducing the probability of clogging.

[0012] Furthermore, a 0.5 mm thick carbide ring is provided at the opening position of each of the dispensing holes.

[0013] Furthermore, the bottom of the rotatable spreading disc is connected to a rotary motor, and its outer edge is provided with a 5 mm high stainless steel guard to prevent sand particles from flying to the side.

[0014] Furthermore, the bottom of the frame is equipped with casters.

[0015] Compared with existing technologies, the beneficial effects of the heavy-duty floor emery spreading device provided by this utility model are: The frame, serving as the basic framework of the entire device, provides stable support for the equipment through its rectangular structure, ensuring the normal operation and durability of all components. Its design ensures the stability of the equipment in various working environments.

[0016] The adjustable-height hopper is used to store raw materials (such as granular materials like corundum) and features height adjustment for convenient material storage and unloading as needed. Its connection to a rotatable spreading disc at the bottom ensures smooth flow of raw materials into the spreading disc.

[0017] The spiral feeding mechanism achieves uniform distribution of diamond abrasive through the combination of a V-shaped rotating chamber, a screw, and an external drive rotating assembly. The distance between the V-shaped rotating chamber and the screw is adjustable, allowing for precise control of the material flow rate and thus improving the uniformity of distribution. The external drive rotating assembly drives the rotation of the V-shaped rotating chamber, ensuring uniform material distribution.

[0018] The deflector plate guides and distributes the diamond grit, ensuring precise application. Its evenly distributed application holes (such as a quincunx pattern) contribute to improved application. Made of galvanized steel, the deflector plate offers enhanced corrosion resistance, and its 25-45° angle further improves the accuracy and efficiency of diamond grit application.

[0019] The rotating function of the spreading disc allows the diamond powder to cover a large area, ensuring uniform distribution. The surface of the spreading disc has multiple radially distributed guide grooves to improve the application effect of the diamond powder. The bottom of the disc is connected to a rotary motor, and the rotation speed can be adjusted as needed to ensure uniform distribution.

[0020] The spreading holes are φ8 mm in size and arranged in a quincunx pattern, which allows for more uniform application of the diamond abrasive. The stepped hole design (upper hole diameter φ9 mm, lower hole diameter φ7 mm) creates a Venturi effect, thereby reducing the probability of clogging and further ensuring the reliability of the equipment.

[0021] Each application hole is fitted with a 0.5 mm thick carbide ring to enhance wear resistance and extend the service life of the application hole.

[0022] The outer edge of the rotatable spreading disc is equipped with a 5 mm high stainless steel guard, which can effectively prevent the diamond powder from splashing during the spreading process, thereby improving the cleanliness of the working environment and the safety of operation.

[0023] The casters at the bottom of the frame facilitate the movement of the equipment on the work site, increasing the flexibility of the device, especially when it is necessary to adjust the position or clean it.

[0024] This device solves the technical problems of uneven application of corundum and difficulty in controlling thickness during heavy-duty floor construction, ensuring the consistency of floor surface hardness and the stability of construction quality. Attached Figure Description

The frame 10 is a rectangular frame structure, with an adjustable height hopper 20 at its top for storing raw materials. The bottom of the adjustable height hopper 20 is connected to the rotatable spreading disc 50, and the surface of the rotatable spreading disc 50 is configured with multiple radially distributed guide grooves. The spiral distributing mechanism 30 is connected to the lower interior of the adjustable height hopper 20, and a guide plate 40 is provided between the spiral distributing mechanism 30 and the rotatable spreading disc 50. The guide plate 40 has evenly distributed spreading holes for precise dispensing of emery.

[0029] In the above technical solution, the spiral material distribution mechanism 30 includes a V-shaped rotating chamber 31, a screw 32, and an external drive rotating assembly 33. The top of the V-shaped rotating chamber 31 is connected to the bottom of the adjustable height hopper 20. The screw 32 is installed at the center of the inside of the V-shaped rotating chamber 31. The outer wall of the V-shaped rotating chamber 31 is engaged with the external drive rotating assembly 33. The external drive rotating assembly 33 is used to drive the V-shaped rotating chamber 31 to rotate, thereby causing the distance between the inner wall of the V-shaped rotating chamber 31 and the screw 32 to change, so as to distribute the material evenly.

[0030] Furthermore, in the above technical solution, a driven gear is provided on the outer wall of the V-shaped rotating chamber 31, which meshes with the driving gear on one side. The center position of the driving gear is connected to a rotary motor, which drives the driving gear to rotate, thereby driving the V-shaped rotating chamber 31 to rotate.

[0031] Furthermore, in the above technical solution, the guide plate 40 is made of galvanized sheet and is set at an angle of 25-45° to the horizontal, with a length of 600 mm.

[0032] Furthermore, in the above technical solution, the size of the spreading holes is φ8 mm, and they are arranged in a plum blossom shape.

[0033] Furthermore, in the above technical solution, a chrome-plated ball bearing guide rail is provided on one side of the bottom of the adjustable height hopper 20 to drive the adjustable height hopper 20 to adjust its height.

[0034] Furthermore, in the above technical solution, the spreading hole is a stepped hole with an upper diameter of φ9 mm and a lower diameter of φ7 mm, forming a Venturi effect and reducing the probability of clogging.

[0035] Furthermore, in the above technical solution, a 0.5 mm thick hard alloy ring is provided at the orifice position of each dispensing hole.

[0036] Furthermore, in the above technical solution, the bottom of the rotatable spreading disc 50 is connected to a rotary motor, and its outer edge is provided with a 5 mm high stainless steel guard to prevent sand particles from flying to the side.

[0037] Furthermore, in the above technical solution, the bottom of the frame 10 is equipped with casters.

[0038] Specifically, the principle of this utility model is as follows: Before use, check whether all components of the device are intact, including the frame, hopper, spreading disc, and spiral distributing mechanism. Adjust the height of the hopper according to the needs of the construction site to ensure that the diamond powder can flow smoothly into the spreading disc. Chrome-plated ball bearing guides can be used during adjustment to ensure precise adjustment of the hopper height. Ensure that the spreading holes and guide plates are not blocked and that the angle of the guide plates is correct to achieve uniform dispensing of diamond powder.

[0039] Place the required granular materials for applying corundum or other flooring materials into the adjustable-height hopper. Ensure the hopper contains sufficient material to avoid shortages during operation. Turn on the power to the device and ensure the rotary motor and external drive rotating assembly are functioning correctly. Use the control system to adjust the rotation speed of the auger distributing mechanism to ensure the corundum is evenly distributed onto the spreading disc. The external drive rotating assembly will drive the V-shaped rotary chamber to rotate, regulating the material flow rate.

[0040] Turn on the rotating spreader disc to begin its rotation. The rotation of the disc will evenly distribute the abrasive powder onto the floor surface. Adjust the rotation speed of the spreader disc according to the construction requirements. The uniformity of the spread can be further adjusted by regulating the angle of the spreader orifices and the guide vanes. The guide vanes direct the material to the appropriate position on the spreader disc, ensuring that there are no blockages or uneven distribution during the spreading process.

[0041] Use the casters at the bottom of the frame to move the equipment to the area where it needs to be spread. Ensure the equipment is parallel to the ground surface to avoid uneven spreading. Observe the spreading effect continuously during operation. If uneven spreading or other problems are found, stop the equipment immediately and check and adjust the position of the spreading holes, guide vanes, and spreading disc.

[0042] After spreading is complete, stop the equipment and turn off the power. Clean the spreading device regularly, especially the spreading holes and guide channels, to prevent material residue from causing blockages. The spreading holes and guide plates can be cleaned with compressed air or a brush. Inspect all mechanical parts for wear, especially the carbide rings and spreading hole areas, to ensure they are in good working order.
