Description

Technical Field

[0001] This invention relates to the field of belt conveyor bottom cleaning technology, and particularly to a belt conveyor bottom cleaning robot. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are widely used in power plants, mines, metallurgy, ports, and other fields for transporting bulk materials. When conveying bulk materials, after the material is unloaded from the bearing surface, one side of the bearing surface turns towards the return belt section via the head roller. With the bearing surface facing the ground, material on the bearing surface that has not been cleaned properly can spill due to the squeezing of the return idlers and belt vibration. The space under the belt conveyor is very limited, and some belt conveyors even have support leg steps, making it extremely inconvenient to collect spilled material. In stockyards, there are often stacker / reclaimer equipment above the belt conveyors, resulting in significant spillage at the bottom and around the belt conveyors, making manual cleaning time-consuming and labor-intensive. Furthermore, manual cleaning requires the belt conveyor to be shut down to ensure the safety of personnel and equipment. Summary of the Invention

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0033] First, combine Figures 1-7 This invention describes a conveyor belt bottom cleaning robot for collecting materials spilled at the bottom of a conveyor belt, with the bottom of the conveyor belt 400mm above the ground. It has a wide range of applications.

[0034] like Figure 1 As shown, the conveyor belt bottom cleaning robot of this embodiment of the invention has: a submachine 1 and a mother machine 2.

[0035] Specifically, such as Figure 1 As shown, the slave machine 1 cleans and collects the material at the bottom of the belt conveyor; the mother machine 2 collects the material collected by the slave machine 1 and conveys the collected material to the belt conveyor.

[0036] Furthermore, such as Figure 2 , 3 As shown, the submachine 1 includes: a cleaning module 11, a material collection module 12, a box-turning module 13, and a loosening module 14; the cleaning module 11 cleans the material; the material collection module 12 is connected to the cleaning module 11, and the material cleaned by the cleaning module 11 is collected by the material collection module 12; the box-turning module 13 is connected to the material collection module 12, and the material collected by the material collection module 12 is turned over by the box-turning module 13; the loosening module 14 is arranged adjacent to the cleaning module 11, and the loosening module 14 loosens the hardened or frozen material.

[0037] Furthermore, such as Figure 2 , 3 As shown, the cleaning module 11 includes: a first roller brush 111 and a pair of side brushes 112; the first roller brush 111 rolls to clean the material, and the pair of side brushes 112 are connected to the first roller brush 111. The pair of side brushes 112 clean and gather the spilled material, and the first roller brush 111 cleans the gathered material.

[0038] Furthermore, such as Figure 2 , 3 As shown in Figure 6, the material collection module 12 includes a material collection box 121. The inlet end of the material collection box 121 is connected to the first roller brush 111, and the material collection box 121 collects the material swept by the first roller brush 111. A baffle 1211 is movably provided at the outlet end of the material collection box 121 to prevent the material in the material collection box 121 from spilling out. In this embodiment, the baffle 1211 is connected to the material collection box 121 by a hinge, so that the baffle 1211 can be flipped open. A pin 1212 is also provided on the baffle 1211, and a corresponding pin hole 1213 is provided on the material collection box 121. The pin 1212 can be inserted into the pin hole 1213 to close the box, and the box can be opened and the material poured out when the pin 1212 is pulled out from the pin hole 1213.

[0039] Furthermore, such as Figure 2 , 3 As shown, the tilting module 13 includes a pair of tilting mechanisms 131, which are respectively located on both sides of the collection box 121. The pair of tilting mechanisms 131 are used to drive the tilting of the collection box 121. In this embodiment, the tilting mechanism 131 is an electric cylinder. The tilting of the collection box 121 is achieved by the extension and retraction of the electric cylinder. When the tilting mechanism 131 tilts the collection box 121, the pin 1212 on the baffle 1211 is pulled out from the pin hole 1213. Under the action of gravity, the baffle 1211 automatically opens, and the material is poured out of the collection box 121, achieving the unloading function.

[0040] Furthermore, such as Figure 3 As shown, the loosening module 14 includes a rotating shaft 141 and loosening teeth 142 mounted on the rotating shaft 141. The rotating shaft 141 rotates, driving the loosening teeth 142 to loosen the hardened or frozen material, making it easier for the first roller brush to clean.

[0041] Furthermore, such as Figure 7 As shown, the top of the submachine 1 is equipped with a pushing mechanism 15, and the moving end of the pushing mechanism 15 is equipped with a second roller brush 151. The pushing mechanism 15 drives the second roller brush 151 to move. The pushing mechanism 15 is used to sweep the material spilled on the steps to the ground, and then clean it through the cleaning module 11. In this embodiment, the pushing mechanism 15 is a pair of electric cylinders. By extending and retracting the electric cylinders, the second roller brush 151 located at the extension and retraction end of the electric cylinders moves back and forth, sweeping the material on the steps down.

[0042] Furthermore, the vertical height of submachine 1 is no more than 300mm, which ensures that submachine 1 can work normally at the bottom of the belt conveyor.

[0043] Furthermore, such as Figure 1 , 4As shown in Figure 5, the mother machine 2 includes: a bucket 21, a lifting device 22, a bucket elevator 23, and a screw conveyor 24. The bucket 21 receives the material collected by the daughter machine 1. The lifting device 22 can be a combination of a drive motor 221 and a rope 222. One end of the rope 222 is connected to the drive motor 221, and the other end is connected to one end of the bucket 21. The drive motor 221 drives the rope 222 to lift the bucket 21. The lifting device 22 is connected to one end of the bucket 21, and lifts one end of the bucket 21, causing the material in the bucket 21 to pour out. The bucket elevator 23 is connected to the other end of the bucket 21. The material in the bucket 21 is lifted by the lifting device 22 and poured onto the bucket elevator 23, where it is lifted. The screw conveyor 24 is located at the top of the bucket elevator 23 and conveys the material lifted by the bucket elevator 23.

[0044] Furthermore, such as Figure 4 As shown, it also includes: a sensing module 25, which is used to sense obstacles.

[0045] In use, the bottom cleaning robot of the belt conveyor moves forward, and a pair of side brushes 112 gather the spilled material on the cleaning path of the first roller brush 111. The first roller brush 111 sweeps the material into the collection box 121. For the material on the step, the second roller brush 151 is pushed by the pushing mechanism 15 on the submachine 1 to push the material on the step down the step, and then the submachine 1 cleans it. When the collection bin 121 is full of material, the slave machine 1 moves to the hopper 21 of the mother machine 2, the pin 1212 is pulled out from the pin hole 1213, the flipping mechanism 131 flips the collection bin 121, and the material in the collection bin 121 is poured into the hopper 21. The slave machine 1 goes out to continue the cleaning work, the mother machine 2 moves to the belt conveyor, the lifting device 22 lifts the hopper 21, and the material is poured onto the bucket elevator 23. After being lifted by the bucket elevator 23, it is transferred to the screw discharger 24. The material is discharged from the screw discharger 24 onto the belt conveyor, completing the cleaning and recycling of the spilled material.

[0046] Above, refer to Figures 1-7 A conveyor belt bottom cleaning robot according to an embodiment of the present invention is described, which can clean and collect materials on the bottom of the conveyor belt and the cement platform of the conveyor belt support, and transport the cleaned materials onto the conveyor belt.
