Description

Technical Field

[0001] This utility model relates to the field of transport machinery technology, and in particular to a belt conveyor. Background Technology

[0002] Belt conveyors are widely used in mining, metallurgy, chemical, casting, building materials and other industries for conveying and production lines, as well as in hydropower station construction sites and ports [3]. They are mainly used to convey crushed materials. Depending on the conveying process requirements, they can be used as a single unit or multiple units can be combined or combined with other conveying equipment to form a horizontal or inclined conveying system.

[0003] Existing patent number CN216154826U discloses a belt conveyor with a cleaning device. It includes a base, with two short poles and two tall poles connected to the left and right sides of the base top, respectively. A crossbar connects the short and tall poles on the same side. A drive roller is rotatably connected between the two short poles, and a driven roller is rotatably connected between the two tall poles. A conveyor belt is sleeved between the drive and driven rollers. A drive component is provided on the short poles to drive the drive roller to rotate. A connecting plate is connected between the two tall poles and located below the driven roller. A waste bin with an open top is located above the connecting plate. A telescopic component is provided on the top of the connecting plate to drive the waste bin to move. A brush roller is rotatably connected inside the waste bin. A second drive component is provided on the waste bin to drive the brush roller to rotate. The brush roller and the drive roller rotate in the same direction. Soft bristles are distributed on the outer peripheral wall of the brush roller, abutting against the lower part of the conveyor belt. This not only effectively collects and removes debris remaining on the conveyor belt but also improves the convenience of cleaning for workers.

[0004] The above solution has the following problems during implementation: the device can only clean debris on the surface of the conveyor belt, and it is difficult to clean stains that are dissolved and adhered to the surface of the conveyor belt by the brush roller, which reduces the cleaning effect of the device on the conveyor belt. In addition, the brush roller of the device is fixedly installed, and when too much dust accumulates in the bristles of the brush roller or it is damaged, the device cannot be disassembled, which reduces the effectiveness of the device. Utility Model Content

[0005] In view of the above-mentioned problems that the brush roller can only clean debris on the surface of the conveyor belt, and that it is difficult to clean stains that are dissolved and adhered to the surface of the conveyor belt by water, and that the brush roller of the device is fixed and cannot be disassembled, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a belt conveyor, including a U-shaped frame, two conveying rollers connected inside the U-shaped frame, a drive motor installed on one side of the U-shaped frame, and the output end of the drive motor passing through the U-shaped frame and connected to the conveying rollers, a spraying mechanism provided inside the U-shaped frame for spraying cleaning liquid, a sleeve connected inside the U-shaped frame, a sponge roller clamped inside the sleeve, and the sponge roller passing through the U-shaped frame, a first belt sleeved between the side of the sponge roller passing through the U-shaped frame and the output end of the drive motor, and a squeezing mechanism provided inside the U-shaped frame for squeezing the sponge roller;

[0007] The extrusion mechanism includes a reciprocating lead screw connected to the mechanism, with one side of the reciprocating lead screw passing through a U-shaped frame. A second belt is fitted between the side of the reciprocating lead screw passing through the U-shaped frame and the sponge roller. A slider is screwed onto the reciprocating lead screw. A fixed rod is connected to the side of the slider near the sponge roller. A positioning rod is connected to the fixed rod. A pressure rod is connected inside the positioning rod. A first spring is provided between the bottom of the positioning rod and the bottom of the pressure rod.

[0008] In a preferred embodiment of the belt conveyor of this utility model, the spraying mechanism includes an L-shaped plate connected to the bottom of the U-shaped frame, a connecting rod connected to the side of the L-shaped plate near the sponge roller, and a spray head connected to the connecting rod.

[0009] In a preferred embodiment of the belt conveyor of this utility model, a hollow column is connected to the sleeve, a limiting rod is connected inside the hollow column, the limiting rod passes through the sleeve and the sponge roller, a locking block is connected to one side of the limiting rod passing through the sponge roller, a rectangular groove is opened on the sponge roller, and a second spring is provided inside the hollow column.

[0010] In a preferred embodiment of the belt conveyor of this utility model, a water tank is provided at the bottom of the U-shaped frame, and a water pump is provided on the water tank.

[0011] In a preferred embodiment of the belt conveyor of this utility model, a material collection box is provided at the top of the U-shaped frame, and a water outlet is provided at the bottom of the material collection box, with the water outlet penetrating through the U-shaped frame.

[0012] In a preferred embodiment of the belt conveyor of this utility model, an installation rod is connected to the bottom of the collection box, a scraper is connected inside the installation rod, and a third spring is provided between the bottom of the scraper and the bottom of the installation rod.

[0013] In a preferred embodiment of the belt conveyor of this utility model, a conveyor belt is sleeved between the two conveyor rollers, and a plurality of rollers are connected inside the U-shaped frame, with the rollers located inside the conveyor belt.

[0014] The beneficial effects of this utility model are:

[0015] 1. By starting the water pump and coordinating with the spraying mechanism, alcohol is sprayed onto the conveyor belt to melt the solidified impurities on the belt. Then, the drive motor rotates, working with two belts and sleeves, to move the sponge roller to melt and wipe away the melted adhesive on the conveyor belt, making the cleaning more thorough. In addition, the reciprocating screw, slider, fixing rod, and positioning rod move the pressure rod to squeeze the sponge roller, squeezing out the alcohol and other liquids adsorbed in the sponge roller. This prevents the sponge roller from working for a long time and adsorbing too much alcohol inside, which would affect the adsorption force of the sponge roller and improve the adsorption effect of the sponge roller.

[0016] 2. By manually rotating the limit rod and pulling it upward, the locking block can be moved out of the inside of the sponge roller, thus disassembling the sponge roller and facilitating its replacement, thereby improving the effectiveness of the device. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Please see Figures 1 to 5 This is the first embodiment of the present invention, providing a technical solution: a belt conveyor, including a U-shaped frame 1, with two conveyor rollers 2 rotatably connected inside the U-shaped frame 1. A drive motor 4 is installed on one side of the U-shaped frame 1. Starting the drive motor 4 can drive the conveyor rollers 2 to rotate, and the output end of the drive motor 4 passes through the U-shaped frame 1 and is fixedly connected to one of the conveyor rollers 2. A spraying mechanism is provided inside the U-shaped frame 1 for spraying cleaning liquid. A sleeve 12 is rotatably connected inside the U-shaped frame 1, and a sponge roller 10 is clamped inside the sleeve 12. The sponge roller 10 passes through the U-shaped frame 1 and can absorb alcohol. A first belt is sleeved between the side of the sponge roller 10 that passes through the U-shaped frame 1 and the output end of the drive motor 4. Starting the drive motor 4 and cooperating with the first belt can drive the sponge roller 10 to rotate, avoiding the situation where the sponge roller 10 can only absorb alcohol on one side. A squeezing mechanism is provided inside the U-shaped frame 1 for squeezing the sponge roller 10.

[0027] The extrusion mechanism includes a reciprocating screw 8 rotatably connected to the sponge roller 10. One side of the reciprocating screw 8 passes through a U-shaped frame 1. A second belt is fitted between the side of the reciprocating screw 8 passing through the U-shaped frame 1 and the sponge roller 10. The rotation of the sponge roller 10, in conjunction with the second belt, drives the reciprocating screw 8 to rotate. A slider 9 is screwed onto the reciprocating screw 8. The rotation of the reciprocating screw 8 drives the slider 9, which in turn drives the transmission along the reciprocating screw 8. A fixing rod 11 is fixedly connected to the side of the slider 9 closest to the sponge roller 10. The movement of the slider 9 drives the fixing rod 11 to move. A positioning rod 1101 is fixedly connected to the fixing rod 11. The movement of the fixing rod 11 drives the positioning rod 1101 to move. A pressure rod 1102 is slidably connected inside the positioning rod 1101. The movement of the pressure rod 1102 causes the sponge roller 10 to be squeezed, squeezing out the alcohol adsorbed in the sponge roller 10. This prevents the sponge roller 10 from working for a long time, which could lead to alcohol adsorption inside the sponge and reduce the adsorption effect of the sponge roller 10. A first spring 1103 is provided between the bottom of the positioning rod 1101 and the bottom of the pressure rod 1102. By providing the first spring 1103, the pressure rod 1102 is always in contact with the outside of the sponge roller 10. A rotating ball is provided on the pressure rod 1102 to reduce the friction between the pressure rod 1102 and the sponge roller 10. A through hole is provided on the pressure rod 1102, through which the water squeezed by the pressure rod 1102 flows out.

[0028] The spraying mechanism includes an L-shaped plate 5 fixedly connected to the bottom of the U-shaped frame 1. A connecting rod 6 is fixedly connected to the side of the L-shaped plate 5 near the sponge roller 10. A spray head 7 is fixedly connected to the connecting rod 6 for spraying liquid.

[0029] A water tank 13 is installed at the bottom of the U-shaped frame 1. The water tank 13 stores alcohol. Alcohol has good volatility, which makes the belt with alcohol attached dry faster and facilitates the subsequent conveying work of the conveyor belt 3. A water pump is installed on the water tank 13. A water pipe connects the water tank 13 and the water pump. The side of the water pump near the spray head 7 is connected to the spray head 7 by a water pipe. When the water pump is started, the alcohol in the water tank 13 is transported to the spray head 7 through the water pipe.

[0030] A collection box 14 is provided at the top of the U-shaped frame 1, and a water outlet is provided at the bottom of the collection box 14. The water outlet is provided through the U-shaped frame 1, and the impurities inside the collection box 14 are discharged through the water outlet.

[0031] An installation rod 15 is fixedly connected to the bottom of the collection box 14. A scraper 16 is slidably connected inside the installation rod 15. A third spring 17 is provided between the bottom of the scraper 16 and the bottom of the installation rod 15. By providing the third spring 17, the top of the scraper 16 is always in contact with the bottom of the conveyor belt 3, which facilitates the scraping of impurities.

[0032] A conveyor belt 3 is fitted between two conveyor rollers 2. Several rollers are rotatably connected inside the U-shaped frame 1, and the rollers are located inside the conveyor belt 3 to provide support for the conveyor belt 3.

[0033] In use, the water pump is started to transport the alcohol inside the water tank 13 to the spray head 7 through the water pipe. The alcohol is sprayed onto the conveyor belt 3 through the spray head 7. At the same time, the drive motor 4 is started to drive the conveyor roller 2 to rotate, which drives the conveyor belt 3 to move. When the conveyor belt 3 moves above the scraper 16, the scraper 16 can scrape off the dust and other impurities adhering to the conveyor belt 3 and let them fall into the collection box 14. The drive motor 4 rotates in conjunction with the first belt and the second belt, which drive the sleeve 12 and the reciprocating screw 8 to rotate respectively. When the sleeve 12 rotates, it drives the sponge roller 10 to rotate, so that the sponge roller 10 absorbs the alcohol on the conveyor belt 3 and melts and wipes off the melted adhesive. When the reciprocating screw 8 rotates, it drives the slider 9 to move on the reciprocating screw 8, thereby driving the fixed rod 11 to move, which in turn drives the positioning rod 1101 to move. The movement of the positioning rod 1101 drives the pressure rod 1102 to move, squeezing the sponge roller 10 and squeezing out the alcohol absorbed in the sponge roller 10.

[0034] Example 2

[0035] Please see Figures 4 to 5This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a hollow column 1201 is fixedly connected to the sleeve 12, and a limiting rod 1202 is slidably connected inside the hollow column 1201. The limiting rod 1202 passes through the sleeve 12 and the sponge roller 10. A locking block 1203 is fixedly connected to one side of the limiting rod 1202 that passes through the sponge roller 10. Manually rotating the limiting rod 1202 moves the locking block 1203. A rectangular groove is provided on the sponge roller 10, and the size of the rectangular groove matches the size of the locking block 1203. When the locking block 1203 moves to the position of the rectangular groove, it pulls the limiting rod 1202 upward. The hollow column 1201 is equipped with a second spring 1204, which is sleeved on the outside of the limiting rod 1202. Pulling the limiting rod 1202 compresses the second spring 1204, and the locking block 1203 moves out from the inside of the sponge roller 10, thereby disassembling the sponge roller 10. Both sides of the U-shaped frame 1 are provided with observation windows, which are located close to the sponge roller 10. The sponge roller 10 can be disassembled by opening the observation windows.

[0036] When in use, first open the observation window, then manually rotate the limit rod 1202 and pull the limit rod 1202 upward. At this time, the second spring 1204 deforms. When the locking block 1203 moves to the position of the rectangular groove, it can drive the locking block 1203 to move out of the inside of the sponge roller 10, thereby disassembling the sponge roller 10 and improving the use effect of the device.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
