[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0021] Please refer to Figures 1-3

[0022] A gear cleaning device includes a first conveyor 1 and a second conveyor 2. The first conveyor 1 and the second conveyor 2 are respectively horizontally installed on the upper and lower parts of an installation frame 3. One end of the installation frame 3 is provided with a turning guide plate 4. The turning guide plate 4 is located at the tail end of the conveying end of the first conveyor 1 and above the head end of the second conveyor 2. Cleaning components are provided above both the first conveyor 1 and the second conveyor 2. The cleaning components are installed on the installation frame 3. The cleaning components include a rolling brush 6 and a water pipe 7. The rolling brush 6 and the water pipe 7 are alternately installed on the installation frame 3 in sequence and are horizontally arranged along the conveying directions of the first conveyor 1 and the second conveyor 2. Among them, the rolling brush 6 is rotatably connected to the installation frame 3. The water pipe 7 is used to connect to an external conveying pump, and a plurality of water spray holes 8 are provided at the lower end of the water pipe 7.

[0023] The first conveyor 1 and the second conveyor 2 adopt existing chain plate conveyors and are horizontally fixedly installed on the installation frame 3 as a whole. The chain plate conveyor is a conveyor that uses a series of chain plates fixed to the traction chain to convey materials in the horizontal or inclined direction. It uses a single-piece steel plate hinged into an endless belt as the traction and load-bearing member of the conveyor, and installs a driving device at the end to make the endless belt rotate cyclically to achieve the transportation of materials. In this embodiment, the single-piece steel plates on the first conveyor 1 and the second conveyor 2 preferably use perforated mesh plates. When cleaning the gears, the cleaning water is conveyed to the water pipe 7 through an external conveying pump. The conveying pump uses a liquid conveying pump, which can increase the pressure of the cleaning water in the water pipe 7 while conveying the cleaning water to the water pipe 7, facilitating the cleaning water to spray out from the spray holes 8 and spray onto the end face of the gear for cleaning the gear. The use of perforated mesh plates facilitates the fall of the cleaning water and avoids the accumulation of the cleaning water on the conveying chain plates of the conveyor.

[0024] The rotary brush 6 includes a roller body and a number of brushes arranged circumferentially along the outer wall of the roller body. The two ends of the roller body are provided with connecting shafts, and the connecting shafts are horizontally rotatably installed on the installation frame 3 through bearings, bearing seats, etc. At the same time, adjacent connecting shafts can be connected by existing pulleys and belts, and the pulley of the connecting shaft at the end is connected to the reduction motor through a belt. The reduction motor can be fixedly installed on the installation frame 3, and the synchronous rotation of multiple roller bodies is realized through the reduction motor, pulleys and belts. When the roller body rotates, the brushes on it rotate accordingly and the brushes use plastic bristles for scrubbing the end face of the gear.

[0025] Specifically, the conveying plates of the first conveyor 1 and the second conveyor 2 (i.e., the endless belt of the chain plate conveyor) are provided with a number of partition plates 5 arranged at intervals. The distance between the partition plates 5 is greater than the diameter of the gear, so that the gear can be placed flat between two partition plates. The height of the partition plate 5 is greater than the thickness of the gear. When the rotary brush 6 rotates to scrub the end face of the gear, since the scrubbing of the gear end face is realized by the rotation of the brush and contact with the gear end face, there will be a situation as Figure 1 shown. The endless belt on the first conveyor 1 rotates clockwise, the gear moves to the right, and the rotary brush 6 rotates clockwise to scrub the end face of the gear. At this time, the gear will receive a leftward thrust from the rotary brush 6, resulting in the problem that the gear is blocked by the rotary brush 6 and cannot move to the right. Therefore, by setting the partition plate 5 with a height greater than the thickness of the gear, a rightward thrust can be provided for the gear, enabling the gear to smoothly pass through the rotary brush 6 and continue to move to the right to complete the scrubbing of the upper end face of the gear.

[0026] When the upper end face of the gear moves to the end of the first conveyor 1 and the washing of the upper end face is completed, the gear slides onto the second conveyor 2 by flipping the guide plate 4, and the lower end face of the gear is turned upwards; specifically, the flipping guide plate 4 includes a vertical plate and an inclined plate, and the included angle a between the vertical plate and the inclined plate is 120°-135°. The vertical plate is vertically located at the conveying end of the first conveyor 1, and the inclined plate is located above the conveying plate of the second conveyor 2. When the partition plate 5 is perpendicular to the inclined plate, the vertical distance from the vertex of the partition plate 5 to the end face of the inclined plate is less than the thickness of the gear. When the gear moves to the conveying end of the first conveyor 1 (i.e., the inflection point of the endless belt), the gear will continue to move horizontally to the right for a certain distance. When the center of gravity of the gear moves out of the inflection point, the right end of the gear will fall first and contact the front partition plate 5. At this time, the gear is in an inclined state. As the endless belt rotates, the inclination of the gear will gradually increase. When the gear completely moves out of the inflection point, the gear is completely erected on the partition plate 5. The lower end of the gear (i.e., the right end when it is in a horizontal state on the first conveyor 1) contacts the partition plate 5, and the upper end of the gear (i.e., the left end when it is in a horizontal state on the first conveyor 1) leans against the vertical plate under the action of the falling inertia at the inflection point. The vertical plate provides a guiding and supporting function for the downward movement of the gear; on the other hand, the distance between the vertex of the partition plate 5 and the end face of the vertical plate is less than the thickness of the gear, preventing the gear from falling onto the inclined plate in advance; as the endless belt rotates, the distance that the lower end of the gear moves horizontally is greater than the distance that the upper end moves horizontally, so the inclination of the gear increases. When the front partition plate 5 in front of the gear is perpendicular to the inclined plate, the lower end face of the gear (i.e., the upper end face when it is in a horizontal state on the first conveyor 1) fits on the inclined plate, and the upper end face is placed on the vertical plate, completing the preliminary flipping of the gear; as the endless belt rotates, the distance between the vertex of the front partition plate 5 and the inclined plate gradually increases. When it increases to be greater than the thickness of the gear, the gear slides off the partition plate 5 and is completely located on the inclined plate, and then slides onto the porous mesh plate of the second conveyor 2 to complete the flipping of the gear. The cleaning component on the second conveyor 2 is the same as the cleaning component on the second conveyor 1 and will not be elaborated here.

[0027] It should be noted that the length of the second conveyor 2 is greater than the long end of the first conveyor 1. After both end faces of the gear are cleaned, the gear continues to move. On the other hand, it also includes a drying component. The drying component includes a blower 9. The blower 9 can use existing hot air blowers or hair dryers. Preferably, a hot air blower is used. Compared with a hair dryer, the hot air blower can blow hot air to the end face of the gear to accelerate the drying of the gear end face. The blower 9 is installed on the installation frame 3 and is located above the second conveyor 2 and obliquely below the first conveyor 1. That is to say, the blower 9 is located above the part where the second conveyor 2 exceeds the first conveyor 1, which can effectively prevent the cleaning water from falling onto the blower 9. Preferably, the blower 9 can be inclined so that the end face of the gear can be blown with inclined hot air, and the redundant cleaning water on the gear end face can be easily blown off by the inclined hot air.

[0028] Specifically, it further includes a third conveyor 10 which is the same as the first conveyor 1 and the second conveyor 2 and is an existing chain plate conveyor. The third conveyor 10 is installed on the installation frame 3 and is located obliquely below the second conveyor 2. A turning guide plate 4 is provided at the end of the installation frame 3 facing the conveying end of the second conveyor 2. A blower 9 is provided above the third conveyor 10. When the upper end face of the gear on the second conveyor 2 is dried, the gear is turned over through the turning guide plate 4 and moved onto the third conveyor 10 to complete the drying of the other end face of the gear.

[0029] A water collecting tank 11 is provided directly below the second conveyor 2 and opposite to the first conveyor 1. The water collecting tank 11 is installed on the ground and is used to collect the cleaning water. Of course, the delivery pump connected to the water pipe can also be placed in the water collecting tank 11 to realize the recycling of the cleaning water. Of course, in order to ensure the cleaning effect of the gear, the delivery pump can also be placed in another box for holding clean cleaning water. The water collecting tank 11 can prevent the cleaning water from flowing around randomly.

[0030] In this article, specific examples are used to elaborate on the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. It is possible to make changes and improvements to the present invention without exceeding the concept and scope defined by the appended claims. In summary, the content of this specification should not be construed as a limitation to the present invention.
