Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an anti-clogging cotton picking head device and a horizontal spindle cotton picking machine. Background Technology

[0002] With the continuous advancement of agricultural mechanization, machine cotton picking has been widely used, with horizontal spindle cotton pickers being the main type, which significantly improves work efficiency compared to manual labor.

[0003] When picking cotton, broken cotton stalks and other impurities enter the picking head of a horizontal spindle cotton harvester along with the seed cotton. As picking continues, if the stalks and other impurities cannot be discharged in time, they tend to accumulate near the triangular area of ​​the picking head. In this area, the stalks are not directly affected by the spindle, but rather by mutual compression between the stalks. The low discharge efficiency makes them prone to accumulation, eventually causing the front picking roller to jam. It is necessary to manually discharge some of the stalks before the machine can continue working, resulting in reduced picking efficiency. Utility Model Content

[0016] One or more technical solutions provided in the embodiments of this utility model have at least the following technical effects or advantages:

[0017] 1. The cotton picking head of this utility model is equipped with a material feeding unit inside. Through the feeding teeth of the material feeding unit, straw and other impurities are subjected to force throughout the entire channel inside the cotton picking head. Therefore, they are continuously pushed to the rear of the cotton picking head, so they will not accumulate inside the cotton picking head. This can effectively solve the problem of blockage inside the cotton picking head, eliminate the need to manually remove straw, and improve picking efficiency.

[0018] 2. Because the feeding unit can ensure the periodic extension and retraction of the feeding teeth by the size and shape of the cam groove, it will slowly extend when in contact with impurities such as straw, and push the impurities to move continuously towards the rear of the cotton picking head. When it is no longer in contact, the feeding teeth can retract into the feeding unit, which does not hinder the normal movement of impurities such as straw, and also avoids the feeding teeth from getting stuck.

[0019] 3. The teeth are mounted side by side on the lever using a bearing structure. If one tooth is damaged and needs to be replaced, only the corresponding tooth needs to be replaced. There is no need to remove the entire row, which is convenient and quick.

[0020] 4. The anti-clogging cotton picking head of this utility model does not require major modifications to the original cotton picking head structure. It only requires the installation of an anti-clogging component and the branching off of the original power source to the feeding unit to work normally, which is easy to implement.

[0021] Additional advantages of this invention will be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0034] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] like Figure 1 As shown, this is the cotton-picking head structure of an existing horizontal spindle-type cotton harvester. It has a front picking roller 1 and a rear picking roller 2 inside the housing, and a triangular cavity on the left side between the front picking roller 1 and the rear picking roller 2. Figure 1 (Shaded area). When picking cotton, broken cotton stalks and other impurities enter the picking head of a horizontal spindle cotton harvester along with the seed cotton. As picking continues, if the stalks and other impurities cannot be discharged in time, they tend to accumulate near the triangular area of ​​the picking head. The stalks in this area are not directly affected by the picking spindle, but rather by mutual compression between the stalks. Low discharge efficiency leads to easy accumulation, eventually causing the front picking roller 1 to jam. It is necessary to manually discharge some of the stalks before work can continue, resulting in reduced picking efficiency. Therefore, it is urgent to design a cotton picking head device with anti-clogging function.

[0036] like Figure 2 As shown, one embodiment of this utility model proposes an anti-clogging cotton picking head device, including a front picking roller 1 and a rear picking roller 2, with an anti-clogging component provided on the side between the front picking roller 1 and the rear picking roller 2, such as... Figure 3 As shown, the anti-clogging component includes a side wall 5, a feeding unit 4, and a grid plate 3. The side wall 5 is fixed to the outer shell of the cotton picking head, and the grid plate 3 and the side wall 5 form a space to accommodate the feeding unit 4. Figure 4As shown, the grid plate 3 has a grid groove 31. The material feeding unit 4 includes a driving mechanism and feeding teeth 45. The feeding teeth 45 are arranged parallel to the grid groove 31. The driving mechanism can drive the feeding teeth 45 to feed the material out of the grid groove 31 and move the material from the front picking roller 1 to the rear picking roller 2.

[0037] like Figure 3 As shown, the middle part of the side wall 5 is an arc-shaped structure, and the two sides of the arc-shaped structure are support plate structures; the middle part of the grid plate 3 is also an arc-shaped structure, and the two sides of the arc-shaped structure are support plate structures; the opening of the arc-shaped structure of the side wall 5 is arranged opposite to the opening of the arc-shaped structure of the grid plate 3, and the radius of the arc-shaped structure of the side wall 5 is larger than the radius of the arc-shaped structure of the grid plate 3. The side wall 5 and the grid plate 3 constitute the housing structure of the drive mechanism. The feeding unit 4 is located on the left side between the front picking roller 1 and the rear picking roller 2. The side wall 5 is installed on the left side of the feeding unit 4 and fixed to the outer wall of the cotton picking head to provide protection. The grid plate 3 is fixedly installed on the right side of the feeding unit 4 to prevent straw and other impurities from entering the interior of the feeding unit 4.

[0038] The cotton picking head of this invention is equipped with a material feeding unit 4. The feeding teeth 45 of the material feeding unit 4 cause straw and other impurities to be subjected to force throughout the entire channel inside the cotton picking head. As a result, they are continuously pushed to the rear of the cotton picking head, so they will not accumulate inside the cotton picking head. This can effectively solve the problem of blockage inside the cotton picking head, eliminate the need to manually remove the straw, and improve picking efficiency.

[0039] The housing structure has openings at both ends, and a cam disk 41 is provided at each opening. The drive mechanism includes a central shaft 44, which is positioned between the two cam disks 41, and both ends of the central shaft 44 are rotatably connected to the cam disks 41 at both ends. The upper cam disk 41 is fixedly mounted on the top of the cotton-picking head and connected to the central shaft 44 via a rolling bearing, while the lower cam disk 41 is fixedly mounted on the bottom of the cotton-picking head and connected to the central shaft 44 via a rolling bearing.

[0040] like Figure 5 , Figure 6 As shown, the upper end of the central shaft 44 protrudes from the cam disk 41, and a transmission gear 46 is mounted on the portion of the central shaft 44 protruding from the cam disk 41. By mounting the transmission gear 46 on the upper end of the central shaft 44, power is transmitted to the central shaft 44, causing the central shaft 44 to rotate synchronously.

[0041] Furthermore, such as Figure 5As shown in the figure (only one set of levers 49 is shown for clarity), the drive mechanism also includes a rotating frame 42 and levers 49. The rotating frame 42 has two parts, one upper and one lower. Both rotating frames 42 are mounted on the central shaft 44 and can rotate together with the central shaft 44. The two rotating frames 42 are respectively mounted on the two ends of the central shaft 44 located inside the gear plate. The two ends of the levers 49 are respectively mounted on the rotating frames 42 at both ends, and the levers 49 can rotate along the central shaft 44 with the rotating frames 42. The teeth 45 are mounted on the levers 49.

[0042] like Figure 9 As shown, a bearing 48 is mounted on the lever 49. Multiple bearings 48 are arranged along the axial direction of the lever 49. Each bearing 48 includes a main bearing, a secondary bearing, and a pin. The main bearing and the secondary bearing are fastened to the lever 49. Figure 6 As shown. The first end of the main tile and the first end of the auxiliary tile are rotatably connected by a pin, and the second end of the main tile and the second end of the auxiliary tile are detachably connected. The tooth 45 is detachably installed on the second end of the main tile.

[0043] like Figure 5 As shown, multiple bearing shells 48 are mounted side-by-side on the lever 49. The teeth 45 are fixed to the lever 49 along with the bearing shells 48 by bolts and can rotate with the lever 49. The teeth 45 are mounted side-by-side on the lever 49 using the bearing shell structure. If one tooth 45 is damaged and needs replacement, only the corresponding tooth needs to be replaced; there is no need to remove the entire row, making it convenient and quick.

[0044] In another preferred embodiment, the radial end of the rotating frame 42 is provided with a mounting sleeve, and both ends of the lever 49 are inserted into the mounting sleeve of the rotating frame 42. The lever 49 and the mounting sleeve are clearance-fitted, or a bearing is installed between the lever 49 and the mounting sleeve, so that the lever 49 can rotate freely within the mounting sleeve of the rotating frame 42.

[0045] Furthermore, such as Figure 7 , Figure 8 As shown, the cam disk 41 is provided with cam grooves 411, and the cam grooves 411 of both cam disks 41 are arranged facing the direction of the rotating frame 42. Figure 6 As shown, both ends of the lever 49 protrude from the rotating frames 42 at both ends. A crank 43 is installed at the end of the lever 49 protruding from the rotating frames 42. A roller 47 is installed on the crank 43. The roller 47 is embedded in the cam groove 411 of the cam disk 41 and can move along the contour of the cam groove 411. The trajectory of the cam groove 411 is a smooth curve, and the smooth curve has an indentation near the center of the cam disk 41. The indentation faces the direction in which the lever tooth 45 is pulled out.

[0046] The cam grooves 411 of the upper cam disk 41 and the lower cam disk 41 have the same shape and size. The crank 43 rotates together with the paddle lever 49. The paddle tooth 45 forms a fixed angle with the crank 43 in the horizontal direction. A roller is mounted on the crank 43, and the roller rotates synchronously with the crank 43. A roller 47 is mounted at the end of the roller. The diameter of the roller 47 is approximately equal to the width of the cam groove 411 and is located inside the cam groove 411. At this time, the cam groove 411 restricts the movement of the roller 47, thereby driving the crank 43 to rotate at a small angle.

[0047] When the crank 43 rotates, the prying tooth 45 also rotates, thereby achieving the periodic extension and retraction of the prying tooth 45 through the contour of the cam groove 411. When the prying tooth 45 rotates to the right, it extends under the restriction of the cam groove 411 and pries out impurities such as straw, causing them to move continuously towards the rear of the cotton picking head. At this time, the straw and other impurities will enter the meshing area of ​​the rear picking roller 2 and continue to move towards the rear of the cotton picking head under the action of the picking rod until they are discharged from the cotton picking head.

[0048] Because the feeding unit 4 can ensure the periodic extension and retraction of the feeding tooth 45 through the size and shape of the cam groove 411, it will slowly extend when in contact with impurities such as straw, and push the impurities to move continuously towards the rear of the cotton picking head. When it is no longer in contact, the feeding tooth 45 can retract into the feeding unit 4, which does not hinder the normal movement of impurities such as straw, and also prevents the feeding tooth 45 from getting stuck.

[0049] The anti-clogging cotton picking head of this utility model does not require major modifications to the original cotton picking head structure. It only requires the installation of an anti-clogging component and the branching off of the original power source to the feeding unit 4 for normal operation, which is easy to implement.

[0050] Based on the above-mentioned anti-clogging cotton picking head device, this utility model embodiment also provides a horizontal spindle cotton picker, which is equipped with the anti-clogging cotton picking head device described in the above embodiment. Since the above-mentioned anti-clogging cotton picking head device has the above-mentioned technical effects, please refer to the above embodiment for the technical effects of the horizontal spindle cotton picker using the anti-clogging cotton picking head device.

[0051] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
