Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment, specifically a cotton harvester with a baling film and a limiting device. Background Technology

[0002] When harvesting cotton, the cotton harvester first uses a divider at the front of the machine to precisely guide rows and individual cotton plants into the harvesting head. Then, the cotton is separated from the plants by a picker with barbs and threads inside the harvester. Behind the harvesting head, a pneumatic conveying system uses a powerful, high-pressure airflow to transport the separated cotton through pipes to the back of the machine. During this process, cotton branches or leaves are discharged. The cotton that has undergone preliminary screening is transported to the machine's storage box, where it is compacted and then rolled up and discharged through a plastic film.

[0003] When harvesting cotton with a cotton harvester, the divider needs to be close to the ground, but at a certain distance. If the divider is too close to the ground, due to uneven ground, it will easily disturb the soil in the uneven areas when guiding the cotton plants, affecting the cotton harvesting efficiency. However, if the divider is too far from the ground, some cotton plants cannot be accurately guided into the picking head during harvesting. This can lead to problems such as incompatible varieties, poor boll opening, and cotton plants being prone to lodging when the fruiting branches are less than 20cm long. Inaccurate plant and row spacing, such as the conventional 64+12 plant and row spacing, can cause misalignment during harvesting. When the plant height is less than 90cm, especially with severe lodging, the cotton harvester's divider cannot gather the cotton plants in time, resulting in missed harvesting. This leads to a low cotton harvesting efficiency, wasting yield and affecting profits.

[0004] In summary, the present invention provides a cotton harvesting machine with a limiting device for baling film to solve the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a cotton harvester with a baling film and a limiting device, thereby solving the problems in the prior art where the cotton harvesting efficiency is low, resulting in wasted output and reduced profits.

[0006] A cotton harvester with a limiting device includes a cotton harvester body, on which multiple divider groups are installed. Each divider group includes two dividers. The cotton harvester body includes a cotton collection box, in which a baling film roller is installed. A baling film is installed on the baling film roller. A joint groove is opened at the end of each divider, and a linkage shaft is rotatably connected in the joint groove. A ridging mechanism is connected to the end of each divider. The ridging mechanism is connected to the divider via a swing angle guide mechanism. The swing angle guide mechanism includes an angle guide plate, one end of which is fixedly connected to the linkage shaft. A worm gear sleeve is sleeved on the linkage shaft. A worm groove is opened on the divider, and a worm gear is installed in the worm groove. The worm gear sleeve meshes with the worm gear. The ridging mechanism includes a ridging head, one end of which has a roller groove, and the other end has a track groove. A counterweight roller is arranged in the roller groove. The angle guide plate is slidably connected to the ridging head.

[0007] Furthermore, a positioning shaft is installed in the joint groove, the positioning shaft movably passes through the middle of the linkage shaft cylinder, and a fixing bolt is installed on the positioning shaft.

[0008] Furthermore, the worm groove is connected to the joint groove, a through hole is provided in the worm groove, a self-locking rotating rod is fixedly connected to the surface of the worm gear rod, the self-locking rotating rod passes through the worm gear rod and is rotatably connected to the through hole, and one end of the self-locking rotating rod passes through the hole and is fixedly connected to an anti-slip rotating block.

[0009] Furthermore, the worm gear is movably disposed within the worm groove, the worm gear sleeve is installed at the end of the linkage shaft cylinder and contacts the worm gear, and the angle guide plate is installed at the bottom of the linkage shaft cylinder.

[0010] Furthermore, the end of the angle guide plate away from the linkage shaft cylinder is a track head, one end of which is slidably inserted into the track groove and slidably connected to the track groove. The top of the angle guide plate is connected to the track groove by a return spring.

[0011] Furthermore, the counterweight roller is rotatably installed in the roller groove, and the edge of the counterweight roller protrudes from the upper and lower ends of the ridging head.

[0012] Furthermore, a reinforcing stop bar is rotatably connected to one side of the divider. One end of the reinforcing stop bar is rotatably connected to one side of the divider via a stop bar bushing, and the other end of the reinforcing stop bar is located on one side of the ridging head.

[0013] Furthermore, a limiting sleeve is installed on one side of the ridging head, and a limiting groove is opened in the middle of the limiting sleeve. The reinforcing stop bar has a "U" shaped structure, and one end of the reinforcing stop bar is inserted into the limiting groove of the limiting sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by incorporating a movable divider, effectively controls the distance between the divider and the ground, avoiding soil disturbance caused by uneven ground, thereby improving cotton harvesting efficiency. Simultaneously, through the cooperation of the ridging mechanism and the sway guide mechanism, the angle can be flexibly adjusted according to the ground height and distribution, ensuring that cotton plants are accurately guided into the picking head. The worm gear limits the position of the linkage shaft cylinder, thus limiting the rotation direction of the ridging head.

[0015] 2. This invention utilizes the meshing design of the worm gear and worm gear sleeve to adjust the angle of the ridging mechanism. The self-locking rotating rod is sleeved on the worm gear, and the meshing between the worm gear and worm gear sleeve achieves the self-locking function of the device, improving operational safety and reliability. The combination of the reinforcing stop bar and the limiting sleeve further optimizes the structural strength. The reinforcing stop bar guides the cotton plants when lifting them, reducing the risk of wear and deformation in complex operating environments and extending the service life. The overall design balances functionality and practicality, significantly improving cotton harvesting efficiency and providing strong support for agricultural production.

[0016] 3. Through the aforementioned structural design, this invention achieves highly efficient adaptability to different terrain conditions. The linkage design between the divider and the ridging mechanism allows the equipment to automatically adjust its angle and height according to ground undulations during operation, ensuring the stability and accuracy of cotton harvesting. Simultaneously, the application of the elastically lifting ridging head effectively prevents soil disturbance caused by the divider being too close to the ground, thereby improving cotton harvesting efficiency and reducing the possibility of impurities entering the soil. Furthermore, the combination of the reinforced baffle and the limiting sleeve not only enhances the overall structural strength of the equipment but also provides additional support for lodged cotton plants, making them easier to guide into the harvesting head and further optimizing the operational effect. This innovative design significantly improves the working efficiency and reliability of the cotton harvester, bringing substantial improvements to agricultural production.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] like Figures 1-7 As shown, the present invention provides a cotton harvester with a limiting device, comprising a cotton harvester body 2, on which multiple divider groups are installed, each divider group including two dividers 1. The cotton harvester body 2 includes a cotton collection box, within which a baling film roller is installed, and a baling film 15 is installed on the baling film roller. A joint groove 6 is provided at the end of each divider 1, and a linkage cylinder 5 is rotatably connected within the joint groove 6. A ridging mechanism 3 is connected to the end of each divider 1, and the ridging mechanism 3 is connected to the divider 1 via a swing angle guide mechanism 9. The feed mechanism 9 includes an angle guide plate 901, one end of which is fixedly connected to the linkage shaft cylinder 5. A worm gear sleeve 8 is sleeved on the linkage shaft cylinder 5. A worm groove 14 is provided on the divider 1. A worm gear rod 11 is installed in the worm groove 14. The worm gear sleeve 8 meshes with the worm gear rod 11. The ridging mechanism 3 includes a ridging head 301. A roller groove 303 is provided at one end of the ridging head 301, and a track groove 304 is provided at the other end. A counterweight roller 302 is provided in the roller groove 303. The angle guide plate 901 and the ridging head 301 are slidably connected.

[0021] The packing film 15 is wound around the surface of the packing film roller in a roll shape, such as... Figure 7 .

[0022] In one embodiment of the present invention, a positioning shaft 7 is installed in the joint groove 6, the positioning shaft 7 movably passes through the middle of the linkage shaft cylinder 5, and a fixing bolt is installed on the positioning shaft 7.

[0023] The joint groove 6 is located on the divider 1 at one end away from the main body 2 of the cotton harvester. The positioning shaft 7 in the joint groove 6 is used to fix the linkage shaft cylinder 5. The linkage shaft cylinder 5 can rotate freely along the positioning shaft 7 in the joint groove 6. The end of the positioning shaft 7 is fixed by a fixing bolt to limit the position of the linkage shaft cylinder 5.

[0024] In one embodiment of the present invention, the worm groove 14 is connected to the joint groove 6. A through hole is provided in the worm groove 14. A self-locking rotating rod 10 is fixedly connected to the surface of the worm gear rod 11. The self-locking rotating rod 10 passes through the worm gear rod 11 and is rotatably connected to the through hole. One end of the self-locking rotating rod 10 passes through the hole and is fixedly connected to an anti-slip rotating block.

[0025] The self-locking rotating rod 10 drives the worm gear rod 11 to rotate in the worm groove 14. When the worm gear rod 11 rotates, it can drive the worm gear sleeve 8 to rotate at the same time. As a result, the linkage cylinder 5 can rotate along the positioning shaft 7, swing the direction of the swing angle guide mechanism 9, and adjust the angle of the ridging mechanism 3.

[0026] In one embodiment of the present invention, the worm gear 11 is movably disposed in the worm groove 14, the worm gear sleeve 8 is installed at the end of the linkage shaft cylinder 5 and contacts the worm gear 11, and the angle guide plate 901 is installed at the bottom of the linkage shaft cylinder 5.

[0027] The worm gear sleeve 8 and the angle guide plate 901 are connected along the outer periphery of the linkage shaft cylinder 5. When the worm gear sleeve 8 rotates, the linkage shaft cylinder 5 can drive the angle guide plate 901 to rotate simultaneously.

[0028] In one embodiment of the present invention, the end of the angle guide plate 901 away from the linkage shaft cylinder 5 is the track head 903. One end of the track head 903 is slidably inserted into the track groove 304 and slidably connected to the track groove 304. The top of the angle guide plate 901 is connected to the track groove 304 by a return spring 902.

[0029] The track groove 304 is set vertically along the ridging head 301. The opening of the track groove 304 is set close to the sway guide mechanism 9, so that the track head 903 of the angle guide plate 901 can be inserted into the track groove 304 and slidably connected. The return spring 902 is connected between the track groove 304 and the angle guide plate 901, so that the ridging mechanism 3 can move up and down along the angle guide plate 901. Under the elastic force of the return spring 902, it is always subjected to a downward elastic force.

[0030] In one embodiment of the present invention, the counterweight roller 302 is rotatably installed in the roller groove 303, and the edge of the counterweight roller 302 protrudes from the upper and lower ends of the ridging head 301.

[0031] When the cotton harvester is ridging, the counterweight roller 302 contacts the ground and pulls the ridging head 301 close to the ground. The ridge head 301 can then gather the fallen cotton and allow it to enter between each group of harvesters 1 for unified cotton harvesting. When the counterweight roller 302 is working, the return spring 902 pulls the ridging head 301, causing the counterweight roller 302 to contact the ground.

[0032] In one embodiment of the present invention, a reinforcing baffle 4 is rotatably connected to one side of the divider 1. One end of the reinforcing baffle 4 is rotatably connected to one side of the divider 1 through a baffle bushing 13, and the other end of the reinforcing baffle 4 is located on one side of the ridging head 301.

[0033] In one embodiment of the present invention, a limiting sleeve 12 is installed on one side of the ridging head 301, and a limiting groove is opened in the middle of the limiting sleeve 12. The reinforcing stop 4 has a "U" shaped structure, and one end of the reinforcing stop 4 is inserted into the limiting groove of the limiting sleeve 12.

[0034] The reinforcing stop 4 is set on the side where the two dividers 1 are close to each other. The reinforcing stop 4 covers one side of the worm gear sleeve 8. When the angle of the ridging head 301 changes, one end of the reinforcing stop 4 rotates along the stop shaft sleeve 13, and the other end slides in the limiting groove, without restricting the range of motion of the ridging head 301. The reinforced baffle 4 not only enhances the stability of the equipment but also effectively prevents external impurities from interfering with key components. The limiting sleeve 12 further improves the overall structural reliability, ensuring efficient operation in complex working environments. Through this ingenious design, the equipment exhibits stronger adaptability to different terrains while reducing the risk of failure due to external factors. Furthermore, the cooperation between the reinforced baffle 4 and the limiting sleeve 12 allows for more flexible angle adjustment of the ridging head 301 without affecting the normal operation of the divider 1, thus ensuring the continuity and stability of cotton harvesting. This design improves equipment durability while providing operators with a more convenient maintenance experience. Example

[0035] like Figure 1 Under normal plant spacing, the ridging mechanism 3 and the divider 1 are set in a straight line in the horizontal direction. When the cotton harvester body 2 is started, the counterweight roller 303 contacts the ground. Under the action of the return spring 902, the ridging head 301 pulls the counterweight roller 303 to gather and collect the cotton plants with smaller height. The ridging head 301 is close to the ground and can collect and guide the small cotton plants, so that they are gathered between the dividers 1.

[0036] The reinforcing stop 4 remains stable under the constraint of the limiting sleeve 12, while allowing a certain degree of movement to adapt to terrain changes. When the cotton harvester encounters uneven ground, the ridging head 301 moves up and down with the terrain. At this time, the reinforcing stop 4 slides accordingly within the limiting groove, ensuring structural stability without affecting the normal operation of the ridging head 301. This design effectively avoids mechanical jamming caused by terrain changes and improves the equipment's adaptability to complex terrain conditions. Example

[0037] like Figure 2 When the plant spacing is too large, the self-locking rotating rod 10 is rotated. When the self-locking rotating rod 10 rotates, it drives the worm gear rod 11 to rotate, which in turn drives the linkage cylinder 5 to rotate. This causes the angle guide mechanism 9 to shift, and the angle guide plate 901 rotates relative to the end of the divider 1, which drives the ridging head 301 to rotate. This increases the cotton plant collection range at the end of the divider 1, adapting to cotton plant planting with various plant spacings and better collecting cotton plants. The worm gear rod 11 limits the position of the linkage cylinder 5, thus limiting the rotation direction of the ridging head 301.

[0038] When the plant spacing is too small, the self-locking lever 10 is rotated in the opposite direction, causing the worm gear 11 to rotate in the opposite direction as well. This changes the rotation direction of the linkage cylinder 5, and the angle of the swing guide mechanism 9 is adjusted accordingly. The angle guide plate 901 deflects in the opposite direction relative to the end of the divider 1, changing the angle of the ridging head 301, thereby reducing the cotton plant gathering range at the end of the divider 1. This adjustment mechanism can flexibly adapt to the operational needs of cotton fields with different plant spacings, ensuring that the cotton harvester maintains efficient cotton harvesting capacity in densely planted areas, while avoiding mechanical interference problems caused by excessively small plant spacing, further improving the equipment's versatility and operational efficiency.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
