Abstract
Description
Technical Field
[0001] The invention relates to the technical field of planting and weeding, in particular to weeding equipment for citrus plantations. Background Art
[0002] During the citrus planting process, the growth of weeds will compete with citrus trees for nutrients, water and sunlight, affecting the growth and development of citrus trees and fruit yield.
[0003] Traditional weeding methods mainly include manual weeding and chemical weeding. Manual weeding is labor-intensive, inefficient, and costly. Although chemical weeding is relatively efficient, long-term use of chemical herbicides can easily lead to soil compaction and environmental pollution, and may also cause weeds to develop resistance. At the same time, chemical residues can also pose a potential threat to the quality of citrus. With the development of agricultural mechanization, some weeding equipment has also appeared on the market, but most of the existing weeding equipment has the problem of poor adaptability. For example, in citrus plantation terrains with different slopes, the weeding depth and angle cannot be adjusted well, which can easily cause damage to the root system of citrus trees or incomplete weeding. Moreover, the stability and flexibility of the equipment need to be improved. It is inconvenient to operate in a complex plantation environment, and it is difficult to meet the diverse weeding needs of citrus plantations. Summary of the invention

[0038] Based on the above-mentioned weeding device for a citrus plantation, as another aspect of the present invention, a method for using the weeding device for a citrus plantation is provided, comprising the following steps:
[0039] Step 1: Install the hood 1 on the mobile vehicle body, and adjust the length of the telescopic rod 4 according to the slope of the citrus planting soil so that the side plate 14 moves in an arc shape inside the hood 1, so as to adjust the position of the side plate 14 up and down, thereby driving the rotating disk 8 to bend up and down with the bottom end of the adjustment plate 7 as the node;
[0040] Step 2: In step 2, since the connection position between the adjustment plate 7 and the guide shaft 20 remains unchanged, the side plate 14 is lowered, causing the movable shaft 18 to begin to lower, thereby realizing the upward tilting of the guide shaft 20. At the same time, the movable shaft 18 rotates inside the guide shaft 20 to play a transmission role for the universal shaft 21.
[0041] Step 3, start the motor inside the chassis 2, the motor drives the transmission shaft 13 to rotate, the transmission shaft 13 transmits power to the transmission box 6, and transmits it to the transmission shaft 13 to make the guide shaft 20 and the rotating disk 8 start to rotate, the rotating disk 8 on the outer wall of the guide shaft 20 increases or decreases according to the slope to adjust the number of the tilling blades 16, and the tilling blades 16 rotate accordingly to perform weeding work. After the motor is started, it rotates for 1 to 2 minutes first, and stops every 30 to 45 minutes of work to perform heat dissipation treatment;
[0042] In step 4 and step 3, the rotation direction is changed by meshing of the bevel gear 23, so that the transmission shaft 13 drives the universal shaft 21 to rotate under the transmission of the two sprockets 22 and the chain.
[0043] In actual use:
[0044] For example, in a citrus plantation hillside area with a slope of 10° to 20°, the hood 1 is first installed on a mobile body equipped with a suitable power source (such as a small tractor or an electric drive chassis), and the length of the telescopic rod 4 is adjusted according to the soil slope. When it is necessary to adapt to the uphill terrain, the telescopic rod 4 is extended, and the side plate 14 moves upward in an arc inside the hood 1, driving the movable shaft 18 to rise, and the guide shaft 20 is tilted upward with the lower end as a node, so that the tilling blade 16 maintains a suitable soil entry angle (such as 30° to 45° with the ground), and at the same time, the number of tilling blades 16 on the rotating disk 8 is increased according to the slope (such as increased to 4 to 5) to enhance the weeding effect. Start the motor in the chassis 2, the motor drives the transmission shaft 13 to rotate, the power is transmitted through the transmission box 6, and the direction is changed through the bevel gear 23. The sprocket 22 and the chain drive drive the universal shaft 21 to rotate, thereby rotating the guide shaft 20 and the rotating disk 8, and the tilling blade 16 starts to rotate to weed. After the motor is started, it will idle for 1 to 2 minutes, and then start working after checking that there is no abnormality in the equipment. It will stop every 30 to 45 minutes to observe the equipment's operating conditions and perform heat dissipation treatment. When working in a flat area, shorten the telescopic rod 4 to keep the tillage blade 16 at a lower depth (such as 5 to 10 cm) into the soil, and appropriately reduce the number of tillage blades 16 on the rotating disk 8 (such as 3) to improve working efficiency.
[0045] It can be seen from such embodiments that the weeding equipment of the present invention can be flexibly adjusted according to different terrains and operational requirements. While ensuring the weeding effect, it effectively protects citrus trees and the equipment itself, and has high practical value and promotion prospects.
[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
