[0002] With the improvement of people's living standards and the enhancement of health awareness, the demand for green organic agricultural products has increased significantly. In order to reduce the application of chemical agents and the harm to the environment and human body, the research and development and application of mechanical weeding equipment in agricultural production have been put on the agenda of agricultural science and technology. At present, due to the shortcomings and deficiencies in structural design, the running tracks of the inter-row mechanical weeding parts for ridge planting agronomic techniques are all straight lines, the weeding operation is in a flat state, the operation and disturbance range is small, the quality and effect of weeding operation are poor, especially it cannot adapt to and meet the use of inter-row weeding operations in ridge planting agronomic techniques. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine the actual needs of the use of inter-row tillage and weeding operations in ridge farming methods, and study and design an inter-row tillage and weeding device to achieve the purpose of expanding the operating range, greatly improving the quality and effect of inter-row tillage and weeding operations, and reducing grass entanglement.

[0004] The purpose of the invention is achieved in this way: a reducer is fixedly mounted on the vertical wall plate of the L-shaped plate frame, a motor is fixedly mounted on the upper end of the reducer, the motor shaft of the motor is connected to the power input shaft of the reducer, a triangular special-shaped planetary gear mechanism is hung and fixedly mounted on the lower side of the horizontal wall plate of the L-shaped plate frame, the driving shaft of the triangular special-shaped planetary gear mechanism is rotatably inserted into the horizontal wall plate of the L-shaped plate frame, the driving shaft is fixedly connected to the power output shaft of the reducer, an active tool rod is rotatably mounted below the central part of the triangular special-shaped planetary gear mechanism, the active tool rod is connected to the upper part of the triangular special-shaped planetary gear mechanism The driving shaft is connected, three layers of active blades are sequentially installed on the lower side of the active knife bar from top to bottom, and driven knife bars I, II and III are uniformly and rotatably installed in sequence on the lower part of the triangular special-shaped planetary gear mechanism and located outside the active knife bar along the circumferential direction. Driven blades are respectively installed on the lower sides of the driven knife bars I, II and III, and the driven blades on the driven knife bars, II and III are respectively matched with the upper, middle and lower active blades on the active knife bar in a shearing manner with vertical dislocation and radial overlap, thereby forming an inter-ridge tillage and weeding device.

[0005] The invention applies the existing triangular-shaped special-shaped planetary gear mechanism to the inter-ridge tillage and weeding device of the ridge farming method. The driven blade not only rotates on its own, but also can realize revolution around the driving shaft on the central part of the triangular-shaped special-shaped planetary gear mechanism. During the operation movement, a circular cycloid running track is formed, which greatly expands the inter-ridge weeding operation range of the driven blade, eliminates missed tillage and weeding, can better loosen the soil, and is beneficial to the root development and growth of crops. During the use of the triangular-shaped special-shaped planetary gear mechanism, the overlap amount of the driven blade and the active blade will increase as the driven blade moves on the triangular track. The change makes the driven blade and the active blade have both shearing cooperation and changing movement of the axis distance during operation, which improves the shearing and crushing effect on weeds and makes the blades less likely to be entangled by weeds. At the same time, the three-layer active blade and the driven blades on the three driven knife bars at different heights shear and cooperate in sequence to form a three-dimensional tillage and weeding operation, which adapts to and meets the requirements of the ridge side position use in the ridge planting agronomic method. It has the characteristics of novel, unique and reasonable structure, good quality of tillage and weeding operation, high efficiency and reliable use, especially providing technical support for inter-row tillage and weeding in ridge planting technology.

[0014] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A ridge-to-ridge weeding device includes a triangular-shaped planetary gear mechanism 4, a reducer 2 is fixedly mounted on the vertical wall plate of an L-shaped frame 3, a motor 1 is fixedly mounted on the upper end of the reducer 2, the motor shaft of the motor 1 is connected to the power input shaft of the reducer 2, a triangular-shaped planetary gear mechanism 4 is suspended and fixed on the lower side of the horizontal wall plate of the L-shaped frame 3, a drive shaft 4-1 of the triangular-shaped planetary gear mechanism 4 is rotatably inserted into the horizontal wall plate of the L-shaped frame 3, the drive shaft 4-1 is fixedly connected to the power output shaft of the reducer 2, an active cutter bar 7 is rotatably mounted below the center of the triangular-shaped planetary gear mechanism 4, and the active cutter bar 7 is connected to the triangular-shaped planetary gear mechanism 4. The driving shaft 4-1 on the angular special-shaped planetary gear mechanism 4 is connected, and three layers of active blades 10 are installed in sequence from top to bottom on the lower side of the active knife rod 7. On the lower part of the triangular special-shaped planetary gear mechanism 4, the driven knife rod Ⅰ5, the driven knife rod Ⅱ6 and the driven knife rod Ⅲ9 are evenly and rotatably installed in sequence along the circumferential direction on the outside of the active knife rod 7. The driven blades 8 are respectively installed on the lower sides of the driven knife rods Ⅰ5, Ⅱ6 and Ⅲ9. The driven blades 8 on the driven knife rods Ⅰ5, Ⅱ6 and Ⅲ9 are respectively shear-matched with the upper, middle and lower active blades 10 on the active knife rod 7 in a vertically staggered and radially overlapping manner.

[0015] When in use, the weeding device is mounted on a tillage weeding machine used in ridge cultivation and randomly moves forward along the ridge. The active cutter bar 7 is placed at the center of adjacent ridges in the field. The rotational power of the motor 1 drives the drive shaft 4-1 to rotate through the reducer 2. The triangular special-shaped planetary gear mechanism 4 makes the active cutter bar 7 and the driven cutter bars Ⅰ, Ⅱ, Ⅲ5, 6, 9 rotate, while making the driven cutter bars Ⅰ, Ⅱ, Ⅲ5, 6, 9 revolve around the active cutter bar 7 synchronously, so as to carry out and complete the three-dimensional tillage weeding operation at the ridges and ridge sides. The three layers of active blades 10 from top to bottom on the active cutter bar 7 cooperate with the driven blades 8 on the driven cutter bars Ⅰ, Ⅱ, Ⅲ5, 6, 9 in turn to carry out and complete the shearing and crushing processing of weeds and soil blocks.

[0016] The invention applies the existing triangular shaped special-shaped planetary gear mechanism to the inter-ridge tillage and weeding device of the ridge farming method, so that the driven blade not only rotates on itself, but also can realize revolution around the driving shaft on the central part of the triangular shaped special-shaped planetary gear mechanism, and a circular cycloid running track is formed during operation. The overlapping amount of the driven blade and the active blade will change as the driven blade moves on the triangular track, so that during operation, the driven blade and the active blade have both shearing cooperation and changing movement of the axis distance. At the same time, the three-layer active blade is sheared and cooperated with the driven blades on the three driven knife rods with different heights in sequence, forming a three-dimensional inter-ridge tillage and weeding operation, which greatly expands the inter-ridge tillage and weeding operation range of the driven blade, adapts to and meets the use requirements of the ridge side part of the ridge planting agronomic method, has the characteristics of no missed tillage and missed weeding, can better loosen the soil, improve the shearing and crushing effect on weeds, and makes the blade not easily entangled by weeds.
