Problems solved by technology

[0003] Seedling avoidance involves the lateral movement of weeding parts. However, the structural design of the existing weeding parts between rice rows cannot adapt to the control strategy of intelligent seedling avoidance. There is a large lateral contact area of ​​the weeding parts, which causes the lateral movement of the seedlings to scrape the soil. Severe, high resistance; at the same time, it also causes soil to accumulate at the base of the rice seedling stem, causing the rice seedling to tilt or be overwhelmed, seriously affecting normal growth

Embodiment 1

[0029] A paddy inter-row weeding component suitable for horizontal control of seedling avoidance, comprising a weeding knife, a stepped shaft, and a walking frame; the stepped shaft is mounted on a weeding machine through the trailing frame, and the weeding knife is mounted on the stepped shaft.

[0030] The weeding knife includes a blade hub installed on a stepped shaft, a plurality of weeding blades and baffles that are evenly distributed in the circumferential direction on the outside of the blade hub, the root of the weeding blade is connected to the blade hub, and the weeding blade is formed from the inner root to the outer blade. arc. In this embodiment, there are two weeding knives, which are symmetrically arranged left and right, and the imitation frame is located in the middle of the two weeding knives.

[0031] The weeding blade includes a front cutting surface, a back cutting surface and a cutting edge; Figure 5 As shown in the side view direction, both the front ...

Embodiment 2

[0039] The inclination angle, back section, and front section of the cutting edge of the weeding blade are selected from the Archimedes spiral under different proportional constants, which are determined by the soil type and the material properties of the weeding blade. The width of the weeding blade is determined by the working parameters of different machine transplanting. , The length design of the weeding blade (that is, the maximum working depth) is determined by the specific weeding operation requirements. The inclination angle of the cutting edge selected by the weeding blade in this embodiment is 30°, the proportional constant of the Archimedes spiral is 31, the width of the weeding blade is 100 mm, and the length is 80 mm.

[0040] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

Abstract

A paddy rice inter-row weeding component suitable for horizontal control of seedling avoidance, including a weeding knife, a ladder shaft, and a copying frame; the ladder shaft is installed on the control frame of the weeder through the copying frame, and the weeding knife is installed on the ladder shaft; The knife includes a blade hub installed on a stepped shaft, a plurality of weeding blades and baffles evenly distributed in the circumferential direction on the outside of the blade hub, the root of the weeding blade is connected to the blade hub, and the weeding blade forms an arc from the inner root to the outer edge shape. The invention has the advantages of simple structure and reliable operation. The soil cutting resistance required by the weeding blade and the horizontal control resistance of seedling avoidance are small, the stability of horizontal seedling avoidance and weeding control is improved, and the horizontal seedling avoidance control is suitable for the horizontal control of seedling avoidance, which belongs to the technical field of agricultural machinery.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a paddy rice inter-row weeding component suitable for horizontal control of seedling avoidance. Background technique [0002] In the rice field ecosystem, weeds compete with rice for growth space, fertilizer nutrients, light, heat and other resources, which is one of the important reasons for the decline in rice yield and quality. Effective control of weed growth is an important link in the growth process of rice. The application of chemical herbicides is currently a widely used weed control method, but long-term, large-scale, and high-frequency application will cause weed resistance, drug resistance, and Harm, environmental pollution and other negative issues. For this reason, vigorously developing mechanical weeding is the key to ensuring the sustainable development of agriculture. However, in actual operation, the change of the curvature of the seedling belt causes the damage of the...
