[0040] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In the description of this utility model, it should be understood that the terms "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0042] The purpose of this invention is to provide a water brush device for cotton harvesters, which can improve the problem of uneven distribution of cleaning fluid in the prior art.

[0043] Please see Figure 1 , Figure 2 and Figure 3To achieve the above objectives, this utility model provides a water brush device for a cotton harvester, including a fixed frame 100, a water distribution component 200 located on one side of the fixed frame 100, a plurality of fixed seats 300 evenly arranged along the length of the fixed frame 100 on the other side, and water brush blades 400 corresponding to each fixed seat 300. The water brush blades 400 are used to clean the spindles, and the cleaning liquid flows out evenly from the staggered holes on the water brush blades 400, thereby achieving continuous brushing of the spindles. The water distribution component 200 includes a water distribution plate 210 and water pipes 220 corresponding to each water brush blade 400. The water distribution plate 210 is used to achieve uniform distribution of the cleaning liquid. The outlet of the water pipe 220 is connected to the flow channel on the water brush blade 400. The inlets of all water pipes 220 are evenly arranged in the circumferential direction of the water distribution plate 210 and are connected to the water distribution plate 210.

[0044] The fixing frame 100 is provided with multiple first through holes 110, each corresponding to a water pipe 220. The first through holes 110 are used for the water supply pipe 220 to pass through. Specifically, after the inlet of the water pipe 220 is connected to the corresponding position of the water distribution plate 210, the outlet of the water pipe 220 passes through the corresponding first through hole 110 and is connected to the corresponding water brush 400. The first through holes 110 enable the inlet and outlet of the water pipe 220 to be located on both sides of the fixing frame 100. The fixing frame 100 can be provided with buckles for the arrangement and fixing of the water pipe 220, reducing the space occupied by the water pipe 220.

[0045] A water distribution component 200 is provided on one side of the fixing frame 100. The water distribution component 200 includes a water distribution plate 210 and water pipes 220. The inlets of all water pipes 220 are evenly arranged around the water distribution plate 210 and are connected to the water distribution plate 210. A fixing seat 300 and a water brush 400 corresponding to the fixing seat 300 are provided on the other side of the fixing frame 100. The water pipes 220 and the water brush 400 are corresponding to each other, and the outlets of the water pipes 220 are connected to the flow channels on the water brush 400. This is used to evenly transport the cleaning liquid in the water distribution plate 210 to the water brush 400, so that the water brush 400 can clean the spindle during the contact process with the spindle. This improves the problem of uneven distribution of cleaning liquid in the prior art, ensures that each spindle is cleaned, and reduces the number of times the spindle wraps around the cotton.

[0046] In one possible implementation, the water distribution assembly 200 further includes a water cup 230 and a nozzle 240. The water cup 230 has a receiving cavity, a water distribution plate 210 is located at the bottom of the water cup 230, and the nozzle 240 is located at the top of the water cup 230. The nozzle 240 has a first channel inside, and the outlet of the first channel communicates with the receiving cavity. The first channel is used to atomize the cleaning fluid into a uniform water mist and discharge it into the receiving cavity. The water cup 230 has a conical structure, and the receiving cavity also has a conical structure. The outlet of the first channel is located at the top center of the conical structure, atomizing the cleaning fluid into a uniform water mist that falls evenly into the small holes in the water distribution plate 210, and then enters the water pipes 220 corresponding to each small hole.

[0047] In one possible implementation, the nozzle 240 further includes a first water inlet channel 241 and a second water inlet channel 242 spaced apart from each other. Both the first water inlet channel 241 and the second water inlet channel 242 are connected to the first channel for the cleaning fluid to enter the first channel. The flow cross-sectional area of ​​the first water inlet channel 241 is larger than that of the second water inlet channel 242. The first water inlet channel 241 and / or the second water inlet channel 242 are connected to control valves for controlling their on / off state or flow rate. When the cotton harvester is harvesting cotton, the first water inlet channel 241 is kept closed and the second water inlet channel 242 is kept open, allowing a small amount of cleaning fluid to enter the water distribution plate 210 and be distributed to the water brush 400 for continuous small-volume cleaning of the spindles. When the cotton harvester is not harvesting cotton, if it turns around in the field, the first water inlet channel 241 is opened and the second water inlet channel 242 is closed. A large amount of cleaning liquid enters the water distribution plate 210 and is distributed to the water brush plate 400. The continuous large water function cleans the spindles, quickly rinses the spindles, ensures the cleanliness of the spindles, and reduces the amount of cotton entangled in the spindles.

[0048] In one possible implementation, the cotton harvester water brush device further includes a locking assembly 500, which includes a clamping plate 510, a pressure rod 520, and a pressure plate 530. The clamping plate 510 is fixedly connected to the fixing frame 100, and a groove is formed on the side of the clamping plate 510 facing the fixing frame 100. The pressure rod 520 includes a first rod 521 and a second rod 522 connected to the first rod 521. The first rod 521 and the second rod 522 are set at an angle. The first rod 521 passes through the groove and can rotate relative to the groove about its own axis. The pressure plate 530 is fixedly connected to the first rod 521 and is used to drive the first rod 521 to rotate so that the second rod 522 abuts against the retaining sleeve 600 to restrict the rotation of the fixing frame 100 relative to the retaining sleeve 600.

[0049] There are two second rods 522, each connected to one end of the first rod 521. The second rods 522 and the first rod 521 can be welded together, or they can be formed by bending the same rod. The second rod 522 connected to the top of the first rod 521 restricts the downward movement of the first rod 521 by abutting against the clamping plate 510. The second rod 522 connected to the bottom of the first rod 521 restricts the upward movement of the first rod 521 by abutting against the clamping plate 510, thus stabilizing the position of the first rod 521 in its axial direction. Plate 530 is fixedly connected to the first rod 521. This connection method can be, but is not limited to, welding. By rotating the pressure plate 530 around the axis of the first rod 521, the first rod 521 can be driven to rotate around its own axis to adjust the position of the second rod 522 on the horizontal plane. The top of the spindle picking device is provided with a downwardly extending sleeve 600. When the cotton picker water brush device rotates to a preset position relative to the spindle picking device, the second rod 522 can be rotated to abut against the sleeve 600 to interfere with the movement of the cotton picker water brush device, thereby limiting the position of the cotton picker water brush device.

[0050] In one possible implementation, a protective plate 130 is fixedly connected to the side of the fixing frame 100 where the water pipe 220 is located. The water pipe 220 is located between the fixing frame 100 and the protective plate 130. The protective plate 130 is used to protect the water pipe 220. The connection between the fixing frame 100 and the protective plate 130 can be, but is not limited to, welding, bolting, etc., as long as the connection between the fixing frame 100 and the protective plate 130 is firm. The fixing frame 100 is provided with a second through hole 120, and the protective plate 130 is also provided with a limiting member 132 and a third through hole 131 corresponding to the second through hole 120. The second through hole 120 and the third through hole 131 are used for the pressure plate 530 to pass through, that is, to make the end of the pressure plate 530 away from the first rod 521 located on the side of the protective plate 130 away from the fixing frame 100. The second through hole 120 and the third through hole 131 have a certain size to provide clearance space for the rotation of the pressure plate 530. The pressure plate 530 is connected to a handle 540, and the handle 540 is connected to the pressure plate 530. Bolt connection can be used. The handle 540 can rotate in the vertical plane relative to the pressure plate 530. The handle 540 is located on the side of the protective plate 130 away from the fixed frame 100. The handle 540 is provided with a limiting groove adapted to the limiting member 132. When the handle 540 drives the pressure plate 530 to rotate, causing the second rod 522 to rotate to abut against the retaining sleeve 600, the limiting groove of the handle 540 abuts against the limiting member 132 through the rotation of the handle 540 relative to the pressure plate 530 in the vertical plane, so that the position of the handle 540 is stable, thereby stabilizing the position of the second rod 522.

[0051] Please see Figure 4 and Figure 5In one possible implementation, the cotton harvester water brush device further includes a height adjustment component 700. The height adjustment component 700 includes a fixing member 710 and an adjusting member 720. The fixing member 710 is fixedly connected to the protective plate 130 and has an internal thread. The adjusting member 720 is rotatably connected to the main frame 800 of the spindle removal device and has an external thread adapted to the internal thread. The internal thread of the fixing member 710 is engaged with the external thread of the adjusting member 720. Rotating the adjusting member 720 causes the fixing member 710 to move up or down in the axial direction of the adjusting member 720 to adjust the distance between the protective plate 130 and the main frame 800, thereby adjusting the relative position of the water brush 400 and the spindle removal device to ensure contact between the water brush 400 and the spindle removal device. In addition, a locking nut is fitted on the external thread of the adjusting component 720. The locking nut is located between the fixing component 710 and the main frame 800. When the distance between the protective plate 130 and the main frame 800 reaches the preset distance, the locking nut is screwed up until it abuts against the bottom of the main frame 800 to restrict the rotation of the adjusting component 720 relative to the main frame 800, thereby ensuring that the distance between the protective plate 130 and the main frame 800 is fixed. If the distance between the protective plate 130 and the main frame 800 needs to be adjusted again in the future, the locking nut can be loosened first before subsequent adjustment can be made.

[0052] Please see Figure 6 In one possible implementation, the cotton harvester's water brush device further includes a gap adjustment plate 900, which is detachably connected to the bottom of the protective plate 130. The gap adjustment plate 900 includes a windbreak portion extending below the protective plate 130. The protective plate 130 has a strip-shaped hole extending in the height direction, and the gap adjustment plate 900 has a corresponding connecting hole. Bolts are inserted through the connecting hole and the strip-shaped hole and secured with nuts, thus fixing the gap adjustment plate 900 relative to the protective plate 130. By inserting bolts at different heights through the strip-shaped hole, the length of the gap adjustment plate 900 extending below the protective plate 130 can be adjusted to reduce the gap between the protective plate 130 and the base frame 1000 of the picking device. This makes it less likely for wind force to disperse within the picking head, ensuring cotton conveying efficiency, reducing the frequency of cotton blockage within the picking head, and improving picking efficiency.

[0053] Based on the above, this application provides a cotton harvester including the cotton harvester water brush device of all the above embodiments. The cotton harvester also possesses all the beneficial effects of the above-described cotton harvester water brush device, and the remaining structure of the cotton harvester can refer to the prior art as long as it can achieve the above objectives.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] This article uses specific examples to illustrate the principles and implementation methods of this utility model.
