Description

Technical Field

[0001] The present invention belongs to the field of weeding devices, and more particularly, to a row-by-row weeding device for a dry-field intelligent weeding machine. Background Art

[0002] A weeding device is a mechanical tool for trimming lawns, vegetation, etc., and is divided into diesel engines and gasoline engines. It consists of a cutter head, an engine, walking wheels, a walking mechanism, blades, a handrail, control, etc. The output speed of the blades is greatly increased by the high-speed rotation of the engine, saving the working time of weeding workers and reducing a large amount of human resources; while the row-by-row weeding device of a dry-field intelligent weeding machine is widely used in various dry-field crop planting scenarios, such as field management of crops such as corn, soybeans, and wheat. In large-scale farmlands, traditional weeding methods are often time-consuming and laborious and have poor effects, while the row-by-row weeding device of an intelligent weeding machine can efficiently process large areas of land, improving agricultural production efficiency and sustainability.

[0003] Among the existing weeding devices, for some low-cost products, when weeding, the weeding machine is manually pushed by workers. For the parts that need to be weeded, the equipment is manually moved to the corresponding position, and the weeding operation is completed by a high-speed rotating mowing rope. This method requires manual operation, and the efficiency is low. Currently, in actual use, at the same time, the diameters of the blades of most weeding machines cannot be changed, so that the weeding machine cannot adjust the weeding range of the blades according to actual needs, wasting more working time to a certain extent. Summary of the Invention

[0004] In view of the problems in the related art, the present invention provides a row-by-row weeding device for a dry-field intelligent weeding machine to overcome the above-mentioned technical problems existing in the related art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention provides a row-by-row weeding device for a dry-field intelligent weeding machine, including a weeding machine main body. A driving cylinder is arranged above the weeding machine main body. The output shaft of the driving cylinder penetrates through the weeding machine main body and is fixedly installed with a moving plate. The moving plate is rotatably installed with a storage disc through a connecting rod. The storage disc is fixedly installed with the output shaft of a first motor. The storage disc is fixedly installed with a second motor. The second motor is fixedly installed with a cutting mechanism. The cutting mechanism includes a fixed frame arranged inside the storage disc. The fixed frame is slidably connected with a cutting knife. The cutting knife is provided with a sliding block. The sliding block is slidably connected inside an arc-shaped chute. The arc-shaped chute is opened on a first gear. The first gear meshes with a second gear.

[0007] Further, the driving cylinder is fixedly installed above the main body of the weeding machine. One end of a connecting rod is fixedly installed on the moving plate, and a receiving tray is rotatably installed at the other end of the connecting rod. The first motor is fixedly installed on the moving plate.

[0008] Further, the second motor is fixedly installed on the receiving tray, and the output shaft of the second motor penetrates through the receiving tray and is fixedly installed on the second gear.

[0009] Further, the fixing frame is fixedly installed inside the receiving tray. The fixing frame is provided with a sliding groove, and a cutting knife is slidably connected to the sliding groove.

Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] Please refer to Figures 1-6 As shown, the present invention is an in-row weeding device for a dry-field intelligent weeding machine, including a weeding machine main body 1. A driving cylinder 2 is arranged above the weeding machine main body 1. The output shaft of the driving cylinder 2 penetrates through the weeding machine main body 1 and is fixedly installed with a moving plate 3. The moving plate 3 is rotatably installed with a storage tray 5 through a connecting rod 4. The output shaft of a first motor 6 is fixedly installed on the storage tray 5. A second motor 7 is fixedly installed on the storage tray 5. The second motor 7 is fixedly installed with a cutting mechanism. The cutting mechanism includes a fixed frame 8 arranged inside the storage tray 5. A cutting knife 9 is slidably connected to the fixed frame 8. The cutting knife 9 is provided with a sliding block 10. The sliding block 10 is slidably connected inside an arc-shaped chute 11. The arc-shaped chute 11 is opened on a first gear 12. The first gear 12 meshes with a second gear 13.

[0032] The working principle of the in-row weeding device for a dry-field intelligent weeding machine proposed by the present invention is as follows: First, move the weeding machine main body 1 to a designated position, and then start the driving cylinder 2. Drive the moving plate 3 to move downward through the output shaft of the driving cylinder 2, thereby driving the storage tray 5 to move downward. After moving to a suitable position, start the first motor 6. Drive the storage tray 5 to rotate through the output shaft of the first motor 6, and then drive the cutting knife 9 to rotate, so as to cut and clean the weeds.

[0033] It should be noted that when the weed range is too large, the second motor 7 can be started, and the output shaft of the second motor 7 drives the second gear 13 to rotate. Since the second gear 13 meshes with the first gear 12, the first gear 12 is driven to rotate, and then the arc-shaped chute 11 is driven to rotate. Since the sliding block 10 is slidably connected to the inside of the arc-shaped chute 11, when the arc-shaped chute 11 rotates, the sliding block 10 is driven to move along the inside of the arc-shaped chute 11, and then the cutting knife 9 is driven to move along the fixed frame 8, so that the cutting knife 9 moves away from the center position of the storage tray 5, and then the rotation range of the cutting knife 9 is increased, so that large-range weed cutting can be carried out, improving work efficiency.

[0034] In one embodiment, for the above-mentioned driving cylinder 2, the driving cylinder 2 is fixedly installed above the weeding machine main body 1. One end of the connecting rod 4 is fixedly installed on the moving plate 3, and the other end of the connecting rod 4 is rotatably installed with the storage tray 5.
