[0002] The self-propelled residual film recycling machine is an agricultural machine used to recycle plastic mulch film residues in farmland. In modern agricultural production, in order to improve crop yield and quality, plastic film covering technology is often used. This technology can retain moisture, keep warm, inhibit weed growth, etc., but it also brings with it the problem of a large amount of residual film after use.

DETAILED DESCRIPTION

[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0017] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0018] Figure 1-4The invention shows an automatic row alignment device for a self-propelled residual film recycling machine, comprising a bracket 1, two crop dividers 2, a left guide plate 3, a right guide plate 4, a lower connecting plate 7, an upper connecting plate 8, a row alignment angle sensor 5, an automatic return assembly 9, a rear wheel angle sensor 12, a controller 10 and a motor 11. The two crop dividers 2 are arranged on both sides of the bracket 1. Both sides of the bracket 1 are provided with an inner cavity, in which a lower connecting plate 7 and an upper connecting plate 8 are connected through a bearing seat 6. The left guide plate 3 and the right guide plate 4 are arranged between the two crop dividers 2, and One end of the left guide plate 3 and the right guide plate 4 are both horizontally arranged at the bottom of each straw divider 2, and the other end thereof is connected to the lower connecting plate 7, and the lower connecting plate 7 is connected to the upper connecting plate 8. A row angle sensor 5 is provided on the bearing seat 6, and the other end of the upper connecting plate 8 is connected to an automatic return assembly 9. A rear wheel angle sensor 12 is provided on the rear wheel of the machine body, and a controller 10 is provided in the machine body control room. A motor 11 is connected to the steering wheel, and the row angle sensor 5, the rear wheel angle sensor 12, and the motor 11 are all electrically connected to the controller 10. Through the straw divider, left and right guide plates, angle sensors, and automatic return assemblies, the residual film recycling machine can accurately align the rows with the cotton stalks, and harvest according to the trajectory of the cotton stalks, thereby improving the efficiency of field operations.

[0019] It is worth mentioning that the specific technology of the automatic return component 9 mentioned above can be found in patent application number CN202220820876.0, and the patent name is "A patent for automatic row return device of a cotton picker", which will not be repeated here.

[0020] like Figure 1 A pointed shell 201 is sleeved on the front end of the straw divider 2 to facilitate the cotton stalks to smoothly enter between the two straw dividers. The edges of the left guide plate 3 and the right guide plate 4 are arranged to be smooth surfaces at the relative positions, so that the cotton stalks can fully contact the left guide plate 3 and the right guide plate 4 when the self-propelled residual film recycling machine is in operation.

[0021] The angle between the slope 202 on the crop divider 2 and the horizontal plane can be designed to be 45 degrees, so that the cotton stalks entering between the two crop dividers 2 do not leave the crop divider 2.

[0022] Working principle of this utility model:

[0023] During the operation of the self-propelled residual film recycling machine, if the deviation occurs, the cotton stalks drive the left guide plate 3 or the right guide plate 4, so that the lower connecting plate 7 and the upper connecting plate 8 swing, and drive the row angle sensor 5 to rotate around point A. The row angle sensor 5 transmits the angle change signal to the corresponding controller 10, and the controller 10 controls the motor 11 to rotate, and further drives the steering wheel to rotate. At this time, the rear wheel of the self-propelled residual film recycling machine 14 is prompted to rotate, and the direction is adjusted. The setting parameters of the controller 11 are adjusted so that the rear wheel angle sensor 12 cooperates with the row angle sensor 5, so that the rear wheel angle sensor 12 feedbacks the angle of rotation of the rear wheel, so that the rotation amplitude and direction of the motor 12 are controlled by the controller 11 until the cotton stalks do not interfere with the left guide plate 3 or the right guide plate 4. At this time, the row angle sensor 5 no longer produces an angle change, and then the automatic return component 9 is started, so that the left guide plate 3 and the right guide plate 4 automatically maintain the middle position. Through the automatic row device of the utility model, the self-propelled residual film recycling machine can automatically move along the cotton stalk planting trajectory.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
