Description

Technical Field

[0001] This utility model belongs to the field of "control devices or systems that are distinguished only by mechanical characteristics", and in particular relates to an automatic cleaning device for a non-powered return belt. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are divided into stationary and mobile types. They use flexible conveyor belts as the material-carrying and traction components, and are continuously operating mechanical devices. The equipment consists of a single, endless, looping conveyor belt between a drive drum and a return drum, supported by multiple idlers at both the upper and lower sections. Material is placed in the upper section, and the friction between the drive drum and the conveyor belt moves the entire device and the goods on it forward. This type of machine is suitable for transporting granular materials or finished products horizontally or at an incline. Belt conveyors are renowned for their simple construction, stable and reliable performance, wide material adaptability, large conveying capacity, and low energy consumption, and are therefore widely used in many fields. However, during operation, the return belt can generate dust when carrying material past the lower idlers, which is detrimental to on-site management and environmental protection.

[0003] The purpose of this invention is to provide an automatic cleaning device for non-powered return conveyor belts in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: an automatic cleaning device for a non-powered return belt, comprising an upper housing, a lower housing, a drive wheel, a driven wheel, a cable tray, a main rod, a bracket, a directional movement device, and a return spring; the drive wheel includes a rubber wheel, a drive wheel bearing, a drive wheel bevel gear, and a drive wheel shaft; the driven wheel includes a driven bevel gear, a driven wheel shaft, a driven wheel bearing, and a ratchet; the main rod includes a mounting rod, a main rod bearing, a brush, a cleaning flat belt, and a flat belt mounting cylinder; the directional movement device includes a guide rod, a lower housing plate, a return spring, a slider, and a locking strip; the return spring... The positioning spring includes a pulley, a thrust spring, and a mounting plate. The upper and lower housings are connected by bolts, and mounting holes are provided on the sides of the upper and lower housings and the bottom of the lower housing for mounting with the driving and driven wheels. The rubber wheel, driving wheel bearing, and driving wheel bevel gear pass through and are fixed to the driving wheel shaft in sequence. The driving wheel bearing is fixed to the upper and lower housings. The driven bevel gear, driven wheel bearing, and ratchet pass through and are fixed to the driven wheel shaft in sequence. The driving and driven bevel gears are located in the enclosed space formed by the upper and lower housings and mesh with each other. The narrow end of the guide rod engages with a ratchet, and the central pin is fixed to the lower housing, allowing the guide rod to rotate around the pin for centering. The slider hole fits onto the wide end of the guide rod, with its arc surface facing upwards, and inserts into the square hole of the retaining strip. The lower housing plate is welded to the lower housing. The restoring spring connects the lower housing plate and the non-protruding end of the retaining strip. The shorter protrusion of the retaining strip with a protruding end inserts into the track of the wiring board, and the longer protrusion of the retaining strip with a protruding end inserts into the hole at one end of the mounting rod. The mounting plate is welded to the lower housing. A pulley presses against the side of the retaining strip and is connected to the mounting plate by a thrust spring. The inner side of the flat mounting cylinder... Main rod bearings are installed at both ends. The outer side of the flat strip mounting cylinder is fixed axially to clean the flat strip, ensuring no movement between the flat strip mounting cylinder and the cleaning flat strip. The mounting rod is used to install mounting cylinders and brushes at required intervals. After installation, it is pressed onto the surface of the return belt. The bracket is installed on the end of the mounting rod that does not cooperate with the clamp and is fixed. The drive wheel provides power to the device, the driven wheel performs displacement conversion, the main rod cleans the belt, and the directional movement can meet the requirement of limiting the main rod to move in a specified direction. The return spring causes the device to perform cyclic execution at a certain time period.

[0005] Preferably, the surface of the rubber wheel is provided with protrusions to increase friction.

[0006] Preferably, the cleaning flat sheet can automatically wrap around the mounting rod during operation and is not affected by the direction of belt rotation.

[0007] Preferably, when the wiring board, directional movement, and return spring work together, the main rod can form a working mode of "moving to a certain distance in one direction and then automatically returning to the initial position".

[0008] Preferably, the alternating cleaning device for flat leather and brushes can increase the cleaning efficiency of the return conveyor belt.

[0009] Preferably, the cleaning flat skin and brushes are arranged in multiple sets, so that even if a single cleaning flat skin or brush is damaged, the entire device will not become ineffective.

[0010] The beneficial effects of this utility model are as follows: This utility model is installed below the return belt. The rubber wheel of the drive pulley presses against the belt surface. When the return belt starts to move, it drives the rubber wheel to rotate, providing working power for the device and enabling simultaneous start and stop of the device and the return belt. The rubber wheel transmits power sequentially from the drive pulley to the driven pulley. The coordinated work of the driven pulley and the directional movement device converts rotational displacement into linear displacement. The direction of movement is limited by the cable guide plate, and a periodic cyclic movement is formed by the return spring. Driven by the directional movement, the main rod drives the cleaning flat belt and brush to reciprocate in the vertical direction of the belt, achieving the purpose of cleaning the belt. This utility model requires no electricity and has a high degree of automation. No on-site personnel are required, reducing the risk of occupational diseases for workers. After cleaning the surface of the return belt, it reduces the probability of adhering substances that may damage the belt and rollers, thus increasing the service life of the belt conveyor. Furthermore, by changing the dimensions of some components, it can be applied to belt conveyors of more sizes and specifications, possessing greater flexibility and applicability.

The rubber wheel (301), the driving wheel bearing (302), and the driving wheel bevel gear (303) pass through and are fixed on the driving wheel shaft (304) in sequence. The driving wheel bearing (302) is fixed with the upper housing (1) and the lower housing (2), and the driven bevel gear (401) and the driven wheel bearing (403) are fixed with the driving wheel shaft (304). The ratchet (404) passes through and is fixed to the driven gear shaft (402) in sequence. The driving bevel gear (303) and the driven bevel gear (401) are located in the closed space formed by the upper housing (1) and the lower housing (2) and mesh with each other. The narrow end of the guide rod (801) engages with the ratchet (404). The middle pin is fixed to the lower housing (2) so that the guide rod (801) can rotate around the pin. The hole of the slider (804) fits into the wide end of the guide rod (801), and the arc surface is inserted into the square hole of the clip (805). The lower housing plate (802) is welded to the lower housing (2). The restoring spring (803) connects the lower housing plate (802) and the non-protruding end of the retaining strip (805). The shorter protrusion of the retaining strip (805) is inserted into the track of the cable tray (5), and the longer protrusion of the retaining strip (805) is inserted into the hole at one end of the mounting rod (601). The mounting plate (903) is welded to the lower housing (2). The pulley (901) presses against the side of the retaining strip (805) and is connected to the mounting plate (601) by the thrust spring (902). Plate (903), the inner ends of the flat skin mounting cylinder (605) are respectively installed with main rod bearings (602), the outer side of the flat skin mounting cylinder (605) is fixed along the axial direction with cleaning flat skin (604) so ​​that there is no mutual movement between the flat skin mounting cylinder (605) and the cleaning flat skin (604), the mounting rod (601) is installed with mounting cylinder (605) and brush (603) at required distance intervals, and after installation, it is pressed on the surface of the return belt, the bracket (7) is installed on the end of the mounting rod (601) that does not cooperate with the clamp (805) and is fixed.

[0022] After installation and fixing, the return belt starts, driving the rubber wheel (301), flat leather mounting cylinder (605), and brush (603) to rotate. At this time, the cleaning flat leather (604) begins to wrap around the surface of the flat leather mounting cylinder (605). After wrapping a certain number of times, when the mounting cylinder (605) rotates, the free end of the cleaning flat leather (604) will pat the surface of the return belt. Under the combined action of the cleaning flat leather (604) and the brush (603), the cleaning work begins to be carried out parallel to the running direction of the return belt. The rubber wheel (301) drives the drive bevel gear (303) to rotate, which in turn drives the driven bevel gear (401) to rotate, which in turn drives the ratchet (404) to rotate. After the ratchet (404) rotates, the guide rod (801) converts the movement of the narrow end into the rotation of the wide end, and drives the slider (804) to push the clip (805) and the mounting rod ( 601) Move away from the rubber wheel (301). At the same time, due to the track setting of the return spring (9) and the guide plate (5), the clip (805) and the mounting rod (601) can only move in one direction before reaching a certain distance. After reaching a certain distance, the return spring (803) will pull the clip (805) and the mounting rod (601) back to the initial position along the long arc track of the guide plate (5). The slider (804) will also return to the initial position of the clip (805) due to the lack of movement constraint. The device will move in the next cycle. When the mounting rod (601) moves, the movement direction of the cleaning flat skin (604) and the brush (603) will be at an angle with the belt running direction. On the basis of increasing the cleaning area, all areas of the return belt are subjected to the dual effects of the cleaning flat skin (604) beating and the brush (603) scrubbing, which increases the cleaning rate of the sticky material.
