Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery technology, specifically a contour cutting disc device. Background Technology

[0002] In agricultural planting, especially for fruit trees, many weeds and climbing plants grow around the fruit trees, seriously affecting their growth. Currently, people either manually pull the weeds, but this is time-consuming, labor-intensive, and wastes a lot of manpower; existing technologies also involve using a robotic arm fixedly connected to a cutting disc to cut the weeds in the field. However, each time the cutting reaches the vicinity of the fruit tree trunk, the robotic arm needs to be controlled to avoid the trunk before cutting, which is very cumbersome and cannot automatically bypass the trunk to cut the weeds. Moreover, the cutting process causes weeds to fly around, and the cut weeds flying everywhere can easily cause injury. To solve the above problems, a vibrating spraying device is proposed. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a contour cutting disc device.

[0004] The specific solution of this utility model is: a contour cutting disc device, comprising: a connecting plate; a rotating swing arm rotatably connected to the bottom of the connecting plate, and a cutting disc at the bottom of the other end of the rotating swing arm, the cutting disc being used to cut weeds; a limiting plate at the bottom of the connecting plate, connecting ears on both the connecting plate and the rotating swing arm, a tension spring between the two connecting ears, one end of the tension spring being connected to the connecting ear of the connecting plate, and the other end being connected to the connecting ear of the rotating swing arm, the tension spring being used to generate tension to rotate the rotating swing arm toward the limiting plate;

[0005] The cutting disc includes:

[0006] A circular plate is disposed at the bottom of the rotating swing arm and is fixedly connected to the rotating swing arm;

[0007] A drive motor is mounted on a rotating arm. The output shaft of the drive motor passes vertically downward through the rotating arm and the circular plate. A rotating seat is fixedly connected to the output shaft of the drive motor. The rotating seat is located directly below the center of the circular plate. Two or more cutting blades are symmetrically arranged on the rotating seat. The cutting blades are used to cut weeds.

[0008] Furthermore, an annular tube is provided on the outer contour of the circular plate, and the annular tube is welded and fixed to the circular plate.

[0009] Furthermore, the bottom of the circular plate is provided with a material guiding mechanism, the material guiding mechanism including:

[0010] A cutting notch is provided, with arc-shaped plates on both sides of the cutting notch, and an inclined plate on the side of the arc-shaped plate away from the cutting notch, forming a guide port between the two inclined plates.

[0011] Furthermore, a buffer section is provided at the feed inlet. The buffer section consists of several flexible chains arranged side by side. The upper end of the flexible chain is connected to the circular plate, and the lower end hangs down naturally.

[0012] Furthermore, the connecting plate is provided with a mounting plate, and the mounting plate is provided with mounting holes for connecting to external devices.

[0013] This invention has the following advantages: It has a simple structure and is easy to use. During weed cutting, the cutting notch is positioned in the cutting direction. When encountering the trunk of a fruit tree, the ring tube contacts the trunk, generating a squeezing force that stretches the tension spring. This causes the rotating arm to rotate in the opposite direction of the limiting plate until it bypasses the trunk. After bypassing the trunk, the cutting disc automatically resets under the tension of the tension spring and the limiting action of the limiting plate. Furthermore, this invention has a material guiding mechanism and a buffer section, which effectively discharges the cut weeds through the material guiding mechanism to the buffer section. The buffer section effectively prevents the cut weeds from splashing and injuring people. Attached Figure Description
