Technical Field

[0001] This utility model relates to the field of concrete equipment structure, and more specifically, it relates to a concrete conveyor belt cleaning structure. Background Technology

[0002] In the production and transportation of concrete, conveyor belts are key conveying equipment used to transport concrete raw materials from the mixing plant to the designated location. However, concrete tends to adhere to the surface of the conveyor belt during transportation, especially during long-term use or shutdown. Some concrete will gradually dry and solidify on the conveyor belt, making it difficult to clean. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete conveyor belt cleaning structure to solve the cleaning difficulties caused by the drying and consolidation of concrete on the conveyor belt.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concrete conveyor belt cleaning structure, including a support frame and a conveyor belt located on the support frame, a water trough located below the conveyor belt is fixedly connected to the support frame, a cleaning roller is provided between the water trough and the conveyor belt, the highest point of the cleaning roller contacts the bottom surface of the conveyor belt, the lowest end of the cleaning roller is located in the water trough, and a motor for driving the cleaning roller is fixedly connected to the support frame.

[0005] The present invention is further configured such that the depth of the water tank gradually increases along the direction of movement of the conveyor belt.

[0006] The present invention is further configured such that the cleaning roller is located above the shallower end of the water tank.

[0007] The present invention is further configured such that a drain gate is rotatably connected to the deeper end of the water tank.

[0008] The present invention is further provided that: a groove is provided at the end of the sewage gate away from its rotation axis.

[0009] The present invention is further configured such that: a brush plate is provided on the top surface of the water tank, the bristles at the top of the brush plate are in contact with the bottom surface of the conveyor belt, and the conveyor belt passes through the cleaning roller and the brush plate in sequence along the forward direction of the conveyor belt.

[0010] The present invention is further configured such that: a guide rail is fixedly connected to the top surface of the water tank, and the brush plate is detachably connected to the guide rail in a sliding connection manner.

[0011] The present invention is further configured such that at least two guide rails are provided on the top surface of the water tank.

[0012] In summary, this utility model has the following beneficial effects: Under the drive of the motor, the surface of the cleaning roller rubs against the surface of the conveyor belt. The water on the cleaning roller wets the residual concrete, making it easier for the concrete to fall into the water tank below due to the friction between the cleaning roller and the conveyor belt. The water in the water tank ensures that the fallen concrete will not dry and solidify in the water tank, making it easy to clean. At the same time, the rotation of the motor can also throw the residue on the cleaning roller into the water tank, preventing the residue from accumulating on the surface of the cleaning roller.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A concrete conveyor belt cleaning structure, such as Figure 1 , Figure 2As shown, the system includes a support frame 1 and a conveyor belt 2 located on the support frame 1. In this embodiment, the support frame 1 includes six support legs and protective plates fixedly connected to the top of the support legs. The protective plates are located on both sides of the conveyor belt 2. The support frame 1 has rollers for driving the conveyor belt 2 and motors for driving the roller assembly to rotate. The motors drive the roller assembly to rotate, thereby transporting the concrete above the conveyor belt 2 from one end of the support frame 1 to the other end. A water tank 3 located below the conveyor belt 2 is fixedly connected to the support frame 1. A cleaning roller 4 is provided between the water tank 3 and the conveyor belt 2. The cleaning roller 4 is rotatably connected between two support legs of the support frame 1. A motor 5 for driving the cleaning roller 4 is fixedly connected to the support frame 1. The motor 5 is fixedly connected to a support leg on one side of the cleaning roller 4 by bolts. A drive shaft is formed at one end of the cleaning roller 4. The drive shaft passes through a support leg and is connected to the motor 5 for transmission. The highest point of the cleaning roller 4 contacts the bottom surface of the conveyor belt 2, and the bottom surface of the conveyor belt 2 and the conveyor belt 2 are used to support... The top surface of the concrete is actually the same surface, ensuring that the cleaning roller 4 can contact the residual concrete on the surface of the conveyor belt 2. The lowest point of the cleaning roller 4 is located in the water tank 3, and the liquid level in the water tank 3 is higher than the lowest point of the cleaning roller 4. At the same time, the surface of the cleaning roller 4 adopts a water-absorbing structure. In this embodiment, the outer layer of the cleaning roller 4 adopts an open-cell rubber composite sponge (such as EPDM sponge). While ensuring the wear resistance of the surface of the cleaning roller 4, it also ensures that the cleaning roller 4 can remain moist during rotation. Meanwhile, under the drive of the motor 5, the surface of the cleaning roller 4 rubs against the surface of the conveyor belt 2. The water on the cleaning roller 4 wets the residual concrete, making it easier for the concrete to fall into the water tank 3 below during the friction between the cleaning roller 4 and the conveyor belt 2. The water in the water tank 3 ensures that the fallen concrete will not dry and solidify in the water tank 3, making it easy to clean. At the same time, the rotation of the motor 5 can also throw the residue on the cleaning roller 4 into the water tank 3, preventing the residue from accumulating on the surface of the cleaning roller 4.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, the depth of the water tank 3 gradually increases along the movement direction of the conveyor belt 2. In this embodiment, the inner cavity of the water tank 3 has a right-angled trapezoidal cross-section, and the inner bottom surface of the water tank 3 forms an inclined surface. The residual concrete falling into the water tank 3 is concentrated along the inner bottom surface of the water tank 3 at one end, which facilitates centralized cleaning. The cleaning roller 4 is located above the shallower end of the water tank 3 to prevent concrete from accumulating below the cleaning roller 4, which would cause the cleaning roller 4 to come into contact with the residue falling into the water tank 3 during water suction. A drain gate 6 is rotatably connected to the deeper end of the water tank 3. The drain gate 6 has a groove 7 at the end away from its rotation axis. When the drain gate 6 is drained, a drain valve 6 is connected to the drain valve 6. When the gate 6 is closed, the latch 7 is located on the side of the drain gate 6 closest to the water tank 3, and the latch 7 is lower than the lowest point of the bottom surface of the water tank 3, that is, the latch 7 is not connected to the water tank 3. The latch 7 makes it easy for the user to apply force when rotating the drain gate 6. The drain gate 6 and the cleaning roller 4 are located at both ends of the water tank 3. When the drain gate 6 is rotated away from the water tank 3, the end of the water tank 3 generates a drain outlet that can discharge the residue and sewage in the water tank 3. After cleaning the water tank 3, the drain gate 6 is closed again. A rubber strip is fixedly connected to the drain gate 6 to ensure the sealing of the inner cavity of the water tank 3 when the drain gate 6 is closed.

[0020] like Figure 1 , Figure 2 As shown, a brush plate 8 is provided on the top surface of the water tank 3. The bristles at the top of the brush plate 8 contact the bottom surface of the conveyor belt 2. Along the forward direction of the conveyor belt 2, the conveyor belt 2 passes through the cleaning roller 4 and the brush plate 8 in sequence. The cleaning roller 4 serves to wet and perform preliminary cleaning, while the brush plate 8 further brushes off the wetted residue, ensuring a cleaning effect. A guide rail 9 is fixedly connected to the top surface of the water tank 3. The brush plate 8 is detachably connected to the guide rail 9 by a sliding connection. The guide rail 9 is U-shaped when viewed from above. One side of the U-shaped opening is for the brush plate 8 to be inserted. When the brush plate 8 is inserted to abut against the other end of the guide rail 9, it is considered clean. The brush plate 8 has been installed. The part of the brush plate 8 outside the opening has a handle, which makes it easy for the user to pull out the brush plate 8. There are at least two guide rails 9 on the top surface of the water tank 3. In this embodiment, there are two guide rails 9. One is used for normal use, and the other is used to insert the new brush plate 8 and then pull out the old brush plate 8 when it is necessary to replace the brush plate 8, so that at least one brush plate 8 is always working. The bristles at the top of the brush plate 8 are higher than the lowest point of the guard plate to reduce the residue that is thrown out due to the shaking of the bristles. When the brush plate 8 is pulled out, the bristles pass under the guard plate through the bending deformation of the bristles.
