Description

Technical Field

[0001] The present application relates to the technical field of agricultural and animal husbandry solid waste treatment equipment, and specifically discloses a cleaning device for a belt conveyor. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor. It is a continuous conveying machine that uses a flexible conveyor belt as a material carrying and traction component. Belt conveyors are widely used in people's production and life because of their simple structure, stable and reliable operation, strong adaptability to materials, large conveying capacity, and low power consumption. Especially in the field of agriculture and animal husbandry, belt conveyors play a very important role. For example, in the agricultural and animal husbandry solid waste industry, belt conveyors are used to transport agricultural and animal husbandry solid waste products, which can maintain continuous and stable work. Compared with manual labor, it greatly improves production efficiency and saves labor costs. However, after a long period of work, agricultural and animal husbandry solid waste will gradually accumulate on the conveyor. Therefore, while ensuring production, we also need to clean the belt conveyor regularly.

[0003] The Chinese patent application number CN211664121U discloses a belt conveyor belt cleaning device, and the utility model provides a belt conveyor belt cleaning device. The belt conveyor belt cleaning device includes a base; four support plates, the four support plates are fixedly mounted on the top of the base, and the four support plates are distributed in a rectangular array; a belt, the belt is arranged on the four support plates; a collection box, the collection box is arranged on the top of the base, the collection box is located between the four support plates, and the collection box is located below the belt; four embedded grooves, the four embedded grooves are opened on the top of the base, and the four embedded grooves are distributed in a rectangular array; four embedded blocks, the four embedded blocks are respectively arranged in the four embedded grooves, and the tops of the four embedded blocks extend to the outside of the base and are fixedly connected to the collection box; the cleaning device provided by the utility model has not only the basic cleaning function, but also the function of the spring The design of the scraper can fit tightly to the belt, which enhances the effect of the scraper on the belt and improves the cleaning effect. However, this design still has certain defects. When the spring is compressed, it can indeed provide an upward force to make the scraper fit tightly to the belt itself. However, if the belt itself is far away from the scraper and the compression of the spring is limited, the scraper will not be able to fit tightly to the belt. Even if the length of the belt from the scraper exceeds the size of the spring itself, the scraper cannot act on the belt and cannot perform cleaning work. Therefore, in view of this, the inventor provides a cleaning device for a belt conveyor to solve the above problems. Utility Model Content

[0004] The utility model is intended to provide a cleaning device for a belt conveyor, which is used to solve the existing problem that due to the limited length of the spring itself, the spring is limitedly compressed by the belt, and then the scraper cannot fit closely with the belt, which ultimately affects the cleaning efficiency.

[0005] In order to solve the above technical problems, the basic scheme of the utility model provides a cleaning device for a belt conveyor, including a telescopic component connected to a support frame and an elastic scraper component located on the top of the telescopic component and capable of scraping off materials adhered to the belt. The telescopic component includes a plurality of first connecting rods vertically symmetrically hinged to the support frame, a plurality of spur gears respectively located at the bottom of the first connecting rods and respectively rotating synchronously with the first connecting rods, and a disc rotatably connected to the support frame, a spiral groove meshing with the spur gears is provided on the disc, and when the disc rotates, the meshing of the spiral groove with the spur gears causes the spur gears to rotate, a driving component for driving the disc to rotate is provided on the base, the top of the first connecting rod is connected to a plurality of second connecting rods hinged from bottom to top and end to end, and also includes a plurality of limit rings for preventing the second connecting rods from naturally retracting, and the limit rings are hinged to the plurality of second connecting rods located at the same horizontal height.

[0006] The principles and effects of this basic solution are:

[0007] Compared with the prior art, when the spiral groove in the utility model rotates, the spur gear meshing with the spiral groove also starts to rotate, thereby causing the first connecting rod that has a synchronous rotation relationship with the spur gear to also start to rotate, thereby driving several second connecting rods hinged at the head and tail to extend or retract, and the elastic scraper assembly located at the top of the second connecting rod is also driven to move closer to or away from the belt. Compared with the traditional design that uses passive compression of the spring to make the cleaning assembly fit the belt, this design is more controllable and has a wider adjustment range, and can be used on belt conveyors with different distances from the cleaning device.

[0008] Compared with the prior art, when the second connecting rod in the utility model has a tendency to naturally retract during operation, because the limiting ring is hinged on the rod body of the second connecting rod, if the rod body continues to move downward, it will be stuck by the limiting ring and will not be able to continue to retract downward, thus playing a limiting role. By setting the limiting ring, the utility model ensures the stability of the telescopic assembly and even the elastic scraper assembly in fitting the belt, ensuring that it will not retract due to external force during operation, thereby affecting the cleaning effect of the device on the belt.

[0009] Furthermore, it also includes a solid waste collection box for storing residual solid waste on the belt, a flat block is provided between the top of the second connecting rod at the uppermost end and the bottom of the solid waste collection box, the bottom of the flat block is hinged to the top of the second connecting rod, and the top of the flat block is fixedly connected to the bottom of the solid waste collection box. The flat block is provided between the top of the second connecting rod at the uppermost end and the bottom of the solid waste collection box, so that the connection between the solid waste collection box and the second connecting rod can be made more stable.

[0010] Furthermore, the elastic scraper assembly includes a fixed rod set in the solid waste collection box, a sliding rod slidably connected to the fixed rod, and a scraper located on the top of the sliding rod, one end of the sliding rod extends into the fixed rod and a spring is arranged between the sliding rod, so that the scraper fits with the belt, thereby scraping off the materials adhering to the belt.

[0011] Furthermore, a concave block is fixedly connected to the side wall of the support frame to provide support for the disc, and the bottom edge of the disc is rotatably connected to the concave block. The concave block is provided to provide an upward support force for the bottom of the disc, thereby enabling the disc to run stably during work.

[0012] Furthermore, it also includes a stand frame arranged on the base, the driving assembly includes a first rotating shaft fixedly connected to the bottom of the disc and a first bevel gear arranged at the free end of the first rotating shaft, the first bevel gear is meshed with a second bevel gear, the second bevel gear is fixedly connected to the second rotating shaft, the second rotating shaft is rotatably connected to the stand frame and the free end of the second rotating shaft is connected to a crank. The setting of the crank allows the operator to adjust the speed of the second rotating shaft by himself, and the setting of the first bevel gear and the second bevel gear meshed with each other transmits the power originally on the second rotating shaft to the first rotating shaft, thereby realizing the driving of the disc.

[0013] Furthermore, a protective cover is installed on the upper surface of the base, which can be detachably covered with the first bevel gear, the second bevel gear, the first rotating shaft, the second rotating shaft and the concave block, thereby preventing solid waste from falling into the drive assembly during the belt cleaning process, thereby ensuring the stability of the overall device operation.

[0014] Furthermore, the rod body of the second connecting rod is provided with a protrusion, and the limiting ring is provided with a recessed part that is hinged with the protrusion. The protrusion and the recessed part are used for hinged cooperation, which makes it more convenient to disassemble and assemble the limiting ring and the second connecting rod.

[0015] Furthermore, the upper surface of the disc is provided with disc-shaped spiral ring strips, the spacing between the ring strips forms a spiral groove, and the width of the ring strips and the spacing of the spiral grooves are adapted to the teeth of the spur gear. The width of the ring strips and the spacing of the spiral grooves are set to be adapted to the teeth, so that the power transmission of the disc to the spur gear is more stable.

[0022] The components that provide support for the disc 8 include but are not limited to the concave block 21 , and the selection criteria are that the components can stably support the disc 8 and will not interfere with the rotation of the disc 8 .

[0023] like Figure 1 and Figure 2As shown, it also includes a solid waste collection box 4 for storing residual solid waste on the belt 12, and a flat block is provided between the top of the second connecting rod 16 at the uppermost end and the bottom of the solid waste collection box 4, the bottom of the flat block is hinged to the top of the second connecting rod 16, and the top of the flat block is fixed to the bottom of the solid waste collection box 4.

[0024] The connecting piece between the bottom of the solid waste collection box 4 and the top of the second connecting rod 16 includes but is not limited to a flat block, which is capable of fixing the solid waste collection box 4, and the surface where the flat block contacts the solid waste collection box 4 can also be provided with an anti-slip layer to enhance the fixing effect.

[0025] like Figure 1 and Figure 2 As shown, the elastic scraper assembly includes a fixed rod 5 set in the solid waste collection box 4, a sliding rod 6 slidably connected to the fixed rod 5 and a scraper 7 located on the top of the sliding rod 6, one end of the sliding rod 6 extends into the fixed rod 5 and a spring is provided between the fixed rod 5.

[0026] The solid waste accumulated in the solid waste collection box 4 needs to be cleaned regularly, and the diameter of the solid waste collection box 4 needs to be larger than the area of ​​the base 1, so that the solid waste is not easy to fall onto the base 1 during cleaning.

[0027] like Figure 1 and Figure 2 As shown, it also includes a stand 10 arranged on the base 1, and the driving assembly includes a first rotating shaft 9 fixedly connected to the bottom of the disc 8 and a first bevel gear 19 arranged at the free end of the first rotating shaft 9, the first bevel gear 19 is meshed with a second bevel gear 20, the second bevel gear 20 is fixedly connected to the second rotating shaft 18, the second rotating shaft 18 is rotatably connected to the stand 10, and the free end of the second rotating shaft 18 is connected to a crank 11.
