Description

Technical Field

[0001] This utility model relates to a mechanical device for weeding between crop rows, belonging to the technical field of weeding equipment. Background Technology

[0002] Inter-row weeding machinery is an important tool in agricultural mechanization. It is mainly used to remove weeds between crop rows, reducing manual labor, increasing efficiency, and avoiding environmental pollution from chemical herbicides. The rotary blades of the inter-row weeding mechanism move in a straight line with the crop rows, removing weeds with a very high weeding rate.

[0003] There are various existing inter-row weeding machines for crops, such as the one disclosed in application number 201822213078.8. However, practical experience has shown that the following technical problems still exist: Existing inter-row weeders are generally suitable for weeding between two rows of crop plants, but they cannot weed simultaneously between multiple rows of plants. For example, they cannot weed simultaneously between three or four rows of plants, which means there is still much room for improvement in weeding efficiency.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a mechanical device for weeding between crop rows, which can simultaneously perform weeding operations between multiple rows of plants. It can be flexibly adjusted according to the row spacing of the crop plants, significantly improving weeding efficiency.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A weeding machine for inter-row crops includes a walking frame. A main support arm is fixed to the bottom of the walking frame and is arranged vertically. There are side support arms arranged parallel to the main support arm on both sides. Both the main support arm and the side support arms are hollow structures. A drive arm and a driven arm are installed between the side support arms and the main support arm and are arranged vertically and parallelly. A drive shaft is installed inside the main support arm and the side support arms. The top end of the drive shaft is connected to the output shaft of the geared motor through a coupling. A cutter head is installed at the bottom end of the drive shaft.

[0007] Furthermore, the drive arm comprises a slidingly disposed outer arm and an inner arm.

[0008] Furthermore, the outer arm is fixed to the bottom of the walking frame, and one end of the inner arm extends out from inside the outer arm, with the extended end of the inner arm fixedly connected to the side support arm.

[0009] Furthermore, an electric telescopic rod is installed inside the drive arm.

[0010] Furthermore, the head of the electric telescopic pole is connected to the inner arm of the drive arm, and the tail of the electric telescopic pole is connected to the outer arm of the drive arm.

[0011] Furthermore, the driven arm comprises a slidingly disposed outer arm and an inner arm, one end of the inner arm extending from inside the outer arm, the end of the outer arm away from the inner arm being fixedly connected to the main support arm, and the end of the inner arm away from the outer arm being fixedly connected to the side support arm.

[0012] Furthermore, bearing seats are installed at the bottom ends of both the main support arm and the side support arm, and the bearing seats are sleeved on the lower end of the drive shaft.

[0013] Furthermore, flanges are fixedly connected to the top ends of both the main support arm and the side support arm, and the flanges are connected to the geared motor.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: In this invention, the geared motor drives the transmission shaft to rotate at high speed within the main support arm and the side support arm. During the rotation, the blade disc rotates, enabling weeding between crop rows. By setting multiple blade discs, weeding can be carried out simultaneously between multiple rows of plants. In this invention, the distance between adjacent blade discs can be flexibly adjusted according to the different row spacing of crop plants, significantly improving weeding efficiency.

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0019] like Figures 1-3As shown in the figure, this utility model provides a mechanical device for weeding between crop rows, including a walking frame 1. A main support arm 2 is fixed to the bottom of the walking frame 1 and is arranged in a vertical direction. There are side support arms 3 arranged parallel to the main support arm 2 on both sides. Both the main support arm 2 and the side support arms 3 are hollow structures. A drive arm 4 and a driven arm 5 are installed between the side support arms 3 and the main support arm 2 and are arranged in parallel vertically.

[0020] The drive arm 4 consists of an outer arm and an inner arm that are slidably disposed. The outer arm is fixed to the bottom of the walking frame 1, and one end of the inner arm extends out from inside the outer arm. The extended end of the inner arm is fixedly connected to the side support arm 3.

[0021] An electric telescopic rod 6 is installed inside the drive arm 4. The head of the electric telescopic rod 6 is connected to the inner arm of the drive arm 4, and the tail of the electric telescopic rod 6 is connected to the outer arm of the drive arm 4. The electric telescopic rod 6 provides power for the extension and retraction of the drive arm 4.

[0022] The driven arm 5 consists of an outer arm and an inner arm that are slidably disposed. One end of the inner arm extends out from inside the outer arm. The end of the outer arm away from the inner arm is fixedly connected to the main support arm 2, and the end of the inner arm away from the outer arm is fixedly connected to the side support arm 3.

[0023] The driven arm 5 extends and retracts synchronously with the driving arm 4, and a stable rectangular structure is formed between the driven arm 5, the driving arm 4, the main support arm 2 and the side support arm 3, ensuring the stability of the main support arm 2 and the side support arm 3 during operation.

[0024] Both the main support arm 2 and the side support arm 3 have a drive shaft 7 inside. Both the main support arm 2 and the side support arm 3 have a bearing seat 11 installed at their bottom ends. The bearing seat 11 is sleeved on the lower end of the drive shaft 7 to provide rotational support.

[0025] The top ends of the drive shafts 7 are connected to the output shaft of the geared motor 9 via couplings 8, and the bottom ends of the drive shafts 7 are equipped with cutter heads 12. The geared motor 9 provides power for the high-speed rotation of the cutter heads 12.

[0026] The top ends of the main support arm 2 and the side support arm 3 are both fixed with flanges 10, and the flanges 10 are connected to the geared motor 9.

[0027] The specific working principle of this utility model is as follows: In this invention, the geared motor 9 drives the transmission shaft 7 to rotate at high speed within the main support arm 2 and the side support arm 3. During rotation, the blade disc 12 rotates, achieving weeding between crop rows. By setting multiple blade discs 12, weeding can be carried out simultaneously between multiple rows of plants. In this invention, the distance between adjacent blade discs 12 can be automatically adjusted to flexibly adjust according to different row spacings of crop plants. During adjustment, the electric telescopic rod 6 drives the drive arm 4 to extend and retract, thereby adjusting the distance between the side support arm 3 and the main support arm 2, and consequently adjusting the distance between adjacent blade discs 12.
