Description
Technical Field
The invention relates to the field of mechanical weeding, in particular to a double-row type flexible weeding component between rice plants.
Background
Chemical weeding is an important method for preventing and controlling paddy weeds, but long-term, large-amount and high-frequency application of the herbicide can easily cause the problems of drug resistance of the weeds, phytotoxicity of crops, environmental pollution and the like. The development of environment-friendly mechanical weeding is realized, and the reduction of the application amount of the herbicide is the key of sustainable development of agriculture. However, due to the small planting distance of rice and the interference of rice rows during weeding, the weeding executive component is difficult to avoid rice plants to selectively prevent and remove weeds among the plants, so that the harm of near-plant weeds among the plants is serious, and the development of a mechanical weeding technology is restricted. Therefore, it is necessary to develop a research on inter-plant weeding parts of rice.
The conventional rice inter-plant weeding parts mainly comprise a counter rotating type, a swinging type and a fixed type, and the difference of weeding effects of the 3 weeding parts is not large. The contra-rotating inter-plant weeding part is a pair of rotating elastic fluted discs. However, the biggest problem of such weeding units is that the weeding units must be operated strictly in line, otherwise the seedling damage rate is increased dramatically. However, the paddy field operation machine has unstable line and changes the bending degree of the seedling belt, so that the row aligning quality is difficult to ensure in the actual operation.
The swing type inter-plant weeding mainly adopts the comb teeth which swing left and right to complete inter-plant weeding, and during traveling operation, because the working comb teeth have gaps, rice plants can pass through the gaps of the comb teeth, so that the dependence of a contra-rotating weeding part on the row is eliminated, but because the comb teeth are shorter and have higher rigidity, and the comb teeth are vertical to the ground during operation, the damage to the root system of rice seedlings is serious; in addition, the weeding effect is greatly influenced by the advancing speed of the machine, is difficult to be matched with the row weeding parts, cannot realize the efficient synchronous weeding of the existing weeds, and limits the application and popularization of the weeding parts.
When the fixed inter-plant weeding component works, the weeding elastic wires cross over the two sides of the rice row and drag, pull or bury and press the inter-plant weeds along with the forward movement of the machine. Such inter-plant weeding techniques also have serious row requirements, otherwise the weeding member may not accurately enter the inter-plant area or the weeding member may not avoid the rice plant, resulting in that the weeds in the inter-plant area cannot be controlled or the rice seedlings are damaged.
Therefore, aiming at the transplanted rice field, the invention controls the operation intensity of the weeding part according to the root soil fixation difference between the rice plant and the weed without aligning the row (avoiding the seedling), and removes the weed among the plants without damaging the rice seedling.

Before the machine works, the weeding machine is fixed on the frame, and the weeding brush fingers are positioned on the weeding parts between adjacent rows, namely the working area is the inter-plant area of rice. And selecting and adjusting the working height, the working inclination angle, the brush finger spacing and the brush finger diameter of the front row and the rear row of brush fingers according to the actual condition of the soil of the transplanted rice field and the growth difference of rice seedlings and weeds.
The method specifically comprises the step of adjusting the working height of a brush finger according to the main body length of the root system of the weeds in a mechanical weeding period (10-25 days of rice transplanting) and the depth of the brush finger in soil is 4-8cm, wherein the working height has the advantage of early growth of transplanted rice, the root system is thicker than the weeds, and the soil fixation capacity is strong, so that mechanical damage to rice seedlings can be avoided. Regarding the working inclination angle, the larger the working inclination angle is, the better the weeding effect is, but the more serious the seedling injury is, in order to obtain higher weeding rate and smaller seedling injury rate, the mechanical weeding strength adopts a progressive mode, namely the working inclination angle adopted by the front row is larger than that adopted by the rear row during adjustment, so that under the condition that the brush fingers of the front row are used for mechanically disturbing the soil, the rice plant root system and the weed root system, the smaller working inclination angle is adopted by the rear row, the secondary soil disturbance strength is reduced, and the rice seedling loss is protected. The brush finger spacing and the brush finger diameter need to be matched with each other, and an arrangement mode that the brush fingers in the front row are relatively sparse in spacing and relatively large in diameter and the brush fingers in the rear row are relatively dense in spacing and relatively small in diameter is adopted. When the weeding brush is in work, the front row of brush fingers weed and disturb soil to form longitudinal strip-shaped disturbance marks, the mechanical strength of the soil between the disturbance marks is greatly weakened, the separation of a weed root system and the soil is facilitated, but the effective operation range is small due to the fact that the brush fingers are large in distance, and weed removal is easy to cause. Therefore, the double-row weeding structure is adopted, the brush finger space corresponding to the back row is small, the operation range is effectively enlarged, the probability of missed weeding is reduced, but the dense brush finger space easily causes mechanical damage to rice seedlings, and therefore the brush finger diameter corresponding to the back row is smaller, and the damage to the rice seedlings is relieved to a certain extent.
When the machine works, the weeding brush fingers can randomly work, because the bending strength of the brush fingers is smaller in the vertical advancing direction, the brush fingers can automatically deform under the blockage of the stem base parts or the roots of rice seedlings when passing through the rice seedlings, and then the rice seedlings are avoided, and after passing through the rice seedlings, the original shape of the brush fingers is restored under the action of the elasticity of the brush fingers, and the weeding operation is continued. In the proceeding direction, the weeding brush fingers have certain depth of penetration into the soil, and the brush fingers have the effects of drawing, raking, pressing and burying and the like on the weed root systems, so that the weed root systems are separated from the soil, and the separated weed root systems can float on the accumulated water in the paddy field, thereby preventing the root systems from contacting with the soil. In addition, although the roots of the weeds which do not float up are not completely separated from the soil, the weeds are seriously damaged mechanically, the growth of the weeds is inhibited, and the purpose of mechanically controlling the weeds is also achieved.
