Description

Technical Field

[0001] This invention belongs to the field of cotton harvester technology, specifically a low-noise cotton harvester side reduction assembly system. Background Technology

[0002] Cotton harvesters are mainly used for cotton picking operations, which can significantly improve picking efficiency and reduce labor costs. They are usually composed of multiple parts such as cotton picking head, machine body, conveyor belt, storage box and control system. They realize the rapid picking and collection of cotton through mechanization and automation. The side reduction assembly system is an important part of the cotton harvester, which mainly plays the role of distributing vehicle pressure and protecting tires. The reducer is one of the core components of the side reduction assembly system, which is responsible for realizing the torque reduction and torque increase function.

[0003] Currently, in order to reduce wear caused by friction between internal parts, the reducer is filled with lubricating oil during use. However, the lubricating oil inside the reducer will be consumed during use, resulting in a decrease in the amount of lubricating oil. As a result, the lubricating oil cannot fully lubricate the parts, making them susceptible to damage. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a low-noise cotton harvester side reduction assembly system, which effectively solves the problem that lubricating oil cannot fully lubricate the parts.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1.

This allows the lubricating oil in the oil tank to enter the oil outlet pipe through the bottom pipe, through hole, top pipe, and movable tube, facilitating the even flow of lubricating oil from each oil outlet head. This intermittent flow of lubricating oil ensures complete lubrication of the parts inside the housing.

[0017] 2. This invention facilitates the extraction and re-entry of used lubricating oil from the tank through the cooperation of the suction pipe, oil pump, and return pipe, enabling the recycling of lubricating oil. Furthermore, the cooperation between the inclined plate, left guide plate, and right guide plate facilitates the flow of lubricating oil, ensuring its complete extraction. Finally, the cooperation between the top plate, fixed plate, mounting frame, and filter plate facilitates the filtration of the lubricating oil entering the tank.

[0018] 3. This invention, through the cooperation between the guide plate and guide column, as well as the return spring and support shaft, facilitates the two limiting plates to be respectively fitted into the two fixed plates, so that both limiting plates can be located at the top of the top plate, thereby limiting the top plate, which in turn facilitates the fixing of the mounting frame and filter plate in the oil tank for filtering the lubricating oil.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figures 1-8 The present invention relates to a low-noise cotton harvester edge reduction assembly system, comprising a housing 1, wherein an input shaft 6 and an output shaft 8 are rotatably connected inside the housing 1, and one end of the input shaft 6 and the output shaft 8 extends to the outside of the housing 1.

The input gear 7 is located below the output gear 5 and the input gear 7 and the output gear 5 mesh with each other. A lubrication mechanism 2 is provided inside the housing 1, and a circulation mechanism 3 and a fixing mechanism 4 are provided on the outside of the housing 1.

[0032] In Example 2, based on Example 1, the lubrication mechanism 2 includes a top pipe 201 fixed to the inner top wall of the housing 1. A movable pipe 202 is movably sleeved inside the top pipe 201. An oil outlet pipe 206 is fixedly connected to one end of the movable pipe 202 located outside the top pipe 201. The oil outlet pipe 206 is located above the output gear 5. Multiple oil outlet heads 205 are evenly spaced at the bottom of the oil outlet pipe 206. A bottom sealing ring 2015 is fixedly connected to the bottom of the top pipe 201, and the bottom sealing ring 2015 is sleeved on the outside of the movable pipe 202. By setting the bottom sealing ring 2015, lubricating oil leakage is prevented. Two L-shaped round rods 2017 are symmetrically and fixedly connected between the inner top wall of the housing 1 and the interior of the jacking pipe 201. A lifting plate 2020 is movably sleeved between the two L-shaped round rods 2017. Two connecting rods 2016 are symmetrically and fixedly connected between the bottom of the lifting plate 2020 and the top of the movable pipe 202. A sealing column 2018 and a top sealing ring 2019 are fixedly connected to the top of the lifting plate 2020. The top sealing ring 2019 is fixed to the outside of the sealing column 2018. A bottom pipe 209 is fixedly connected to the top of the housing 1. An oil tank 208 is fixedly connected to the top of the bottom pipe 209. The outside of the oil tank 208 is fixed. The housing 1 is connected to an oil injection pipe 207. A through hole is provided at the top of the housing 1. A bottom pipe 209 connects to a top pipe 201 through the through hole. The inner diameter of the bottom pipe 209 is equal to the inner diameter of the through hole. The outer diameter of the sealing column 2018 is equal to the inner diameter of the through hole, and the sealing column 2018 is located directly below the through hole. A rotating shaft 204 is rotatably connected inside the housing 1. The rotating shaft 204 is located between the oil outlet pipe 206 and the output gear 5. A side plate 2013 is fixedly connected to one end of the rotating shaft 204. A movable rod 2011 is rotatably connected to the side of the side plate 2013 away from the rotating shaft 204. A U-shaped... A round rod 2014, a sleeve plate 2010 is movably sleeved on the outer side of the U-shaped round rod 2014, the sleeve plate 2010 is fixedly sleeved on the outer side of the movable tube 202, the top of the side plate 2013 is rotatably connected to the outer side of the sleeve plate 2010, a vertical plate 2012 is fixedly sleeved on the middle of the outer side of the U-shaped round rod 2014, a rotating shaft 204 passes through the vertical plate 2012 and is rotatably connected to the vertical plate 2012, the vertical plate 2012 is set to support the rotating shaft 204 to ensure the stable rotation of the rotating shaft 204, an external gear 203 is fixedly installed on the outer side of the rotating shaft 204, the external gear 203 is meshed with the output gear 5;

[0033] When the output shaft 8 and output gear 5 rotate, the output gear 5 meshes with the external gear 203, thereby driving the rotating shaft 204 to rotate and the side plate 2013 to rotate. Then, the movable rod 2011 drives the sleeve plate 2010 to reciprocate along the U-shaped round rod 2014, while the movable tube 202 reciprocates up and down. Then, the two connecting rods 2016 drive the lifting plate 2020 to slide back and forth along the two L-shaped round rods 2017. When the lifting plate 2020 rises, the sealing column 2018 is inserted into the through hole to seal the through hole. When the lifting plate 2020 falls, the sealing column 2018 is removed from the through hole. At this time, the lubricating oil in the oil tank 208 enters the top tube 201 through the bottom tube 209 and the through hole, and flows out evenly from each oil outlet 205 through the movable tube 202 and the oil outlet tube 206. Finally, the lubricating oil flows out intermittently to completely lubricate the parts inside the housing 1 and reduce the noise during the operation of the parts.

[0034] In Example 3, based on Example 1, the circulation mechanism 3 includes an oil pump 301 fixed to the top of the tank 1. A return oil pipe 307 is fixedly connected between the oil pump 301 and the oil tank 208. An oil suction pipe 302 is fixedly connected between the oil pump 301 and the tank 1. The end of the oil suction pipe 302 away from the oil pump 301 is located on the outer side of the tank 1 near the bottom. A left guide plate 303, a right guide plate 304, and an inclined plate 305 are fixedly installed on the inner bottom wall of the tank 1. Both the left guide plate 303 and the right guide plate 304 are fixedly connected to the inclined plate 305. A top plate 306 is provided above the oil tank 208. A rubber pad 308 is fixedly connected to the bottom of the top plate 306. The bottom of the rubber pad 308 is in contact with the top of the oil tank 208. The rubber pad 308 is placed between the oil tank 208 and the top plate 306 to ensure the sealing of the oil tank 208. An installation frame 3010 is provided inside the oil tank 208. A filter plate 3011 is fixedly connected inside the installation frame 3010. Two fixing plates 309 are symmetrically fixedly connected to the top of the installation frame 3010. The top plate 306 is fixedly sleeved on the outside of the two fixing plates 309. The connection between the return oil pipe 307 and the oil tank 208 is located above the installation frame 3010.

[0035] First, place the mounting frame 3010 and filter plate 3011 inside the oil tank 208 until the rubber pad 308 is at the top of the oil tank 208. Then, start the oil pump 301 to draw the used lubricating oil from the tank 1 through the suction pipe 302. Under the action of the left guide plate 303, the right guide plate 304, and the inclined plate 305, the lubricating oil is guided so that the used lubricating oil in the tank 1 is completely drawn out. The drawn lubricating oil then re-enters the oil tank 208 through the return pipe 307, realizing the recycling of the lubricating oil. When the lubricating oil enters the oil tank 208, it is filtered through the filter plate 3011 to remove impurities from the lubricating oil.

[0036] In Example 4, based on Example 1, the fixing mechanism 4 includes a guide plate 401 located between the oil tank 208 and the housing 1. The guide plate 401 is movably sleeved on the outside of the bottom tube 209. Two support shafts 405 are symmetrically rotatably connected to the top of the guide plate 401. The oil tank 208 is located between the two support shafts 405. Limiting plates 404 are fixedly connected to the top of each of the two support shafts 405. Handles 403 are fixedly connected to the top of each of the two limiting plates 404. The two limiting plates 404 are located on the top of the top plate 306, and the two limiting plates 404 are respectively sleeved on the outside of the two fixing plates 309. Two guide pillars 402 are symmetrically fixedly connected between the oil tank 208 and the housing 1. The guide plate 401 is movably sleeved on the outside of the two guide pillars 402. Two return springs 406 are symmetrically fixedly connected between the guide plate 401 and the oil tank 208. The two return springs 406 are respectively sleeved on the outside of the two guide pillars 402.

[0037] First, place the mounting frame 3010 and filter plate 3011 inside the oil tank 208, ensuring the rubber pad 308 is in contact with the top of the oil tank 208. Then, pull the two handles 403 upwards, causing the two limiting plates 404 to rise. The guide plate 401 then slides upwards along the two guide posts 402 via the two support shafts 405. At this time, both return springs 406 are compressed. Next, rotate the two limiting plates 404 and place them on the outside of the two fixed plates 309. Then, release the two handles 403. The guide plate 401 then slides downwards along the two guide posts 402 under the elastic force of the two return springs 406. The two supporting shafts 405 then move the two limiting plates 404 downwards until they both abut against the top of the top plate 306, thus limiting the top plate 306. Finally, fix the mounting frame 3010 and filter plate 3011 inside the oil tank 208 to filter the lubricating oil.
