Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a weeding assembly suitable for mechanical weeding operations between paddy field rows. Background Art

[0002] With the increasing demand for green organic rice in my country, the use of less or no chemical herbicides in rice fields has become a development trend. Mechanical weeding machines have been used in paddy field inter-row weeding operations, providing technical support for the production of green organic rice. At present, paddy field inter-row weeding wheels are mostly used as weeding working parts on paddy field inter-row weeding machines. During operation, the paddy field inter-row weeding wheel relies on gravity to extend into the paddy field soil. As the tool moves forward, it rotates passively under the resistance of the paddy field mud and water, cutting off the weed roots in the paddy field inter-row or picking them out of the soil layer, so that the weeds float on the water surface and die, completing the paddy field inter-row weeding. However, since the existing paddy field inter-row weeding wheels are all rigid integral structures connected by metal weeding plate teeth and weeding wheel discs, they are easy to adhere to the soil during weeding and slipping occurs, which not only increases the traction force of the operation, but also has low weeding efficiency and poor weeding quality, and cannot meet the technical requirements of paddy field inter-row weeding. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of inter-row weeding operations in paddy fields, and design a bionic flexible paddy field inter-row driven weeding unit with a new structure, so as to achieve good weeding quality, high efficiency, small traction resistance, and provide technical support for mechanical weeding between paddy fields.

[0004] The purpose of the invention is achieved in the following way: a driving main shaft is rotatably mounted on the middle part of the inner side of the driving box housing, a driving sprocket is fixed on the middle part of the driving main shaft, active bevel gears are fixed symmetrically on the left and right ends of the driving main shaft, and driving half shafts are symmetrically and rotatably mounted on the left and right sides of the driving box housing and located outside the two ends of the driving main shaft, a downward angle α is set between the axis of the driving half shaft and the axis of the driving main shaft, and the driven bevel gear is fixed on the driving half shaft On the inner end portion, the driven bevel gear is meshed with the active bevel gear, and bionic flexible weeding wheels are respectively fixed on the outer ends of the driving half shafts on the left and right sides; the structure of the bionic flexible weeding wheel is: a plurality of cylindrical seats are evenly fixed along the circumferential direction on the circumferential edge of the spoke plate fixed to the outer end portion of the driving half shaft, and the upward inclination angle β between the axis line of the cylindrical seat and the vertical line of the spoke plate is the same as the downward inclination angle α between the axis line of the driving half shaft and the axis line of the driving main shaft, and a pin can be used to fix the outer side of the cylindrical seat. The rod seat is hingedly mounted to swing back and forth, and the web board return pins and limit pins of the same number as the cylinder seat are respectively installed on the spoke plate, and the web board return torsion spring is sleeved on the web board return pin, and the two ends of the web board return torsion spring are respectively in extrusion contact with the rod seat and the limit pin; the left support rod of the web board, the middle support rod of the web board, and the right support rod of the web board are respectively hingedly mounted on the rod seat in sequence so as to swing back and forth through the left support rod shaft, the middle support rod shaft, and the right support rod of the web board, and the left pin and the right pin are fixed on the rod seat, and the left torsion spring and the web board are used to adjust the web board opening. The right torsion spring for adjusting the opening is respectively mounted on the left pin shaft and the right pin shaft, and the two ends of the left torsion spring for adjusting the opening of the web board are respectively in extrusion contact with the middle support rod of the web board and the left support rod of the web board, and the two ends of the right torsion spring for adjusting the opening of the web board are respectively in extrusion contact with the middle support rod of the web board and the right support rod of the web board, and an elastic web board is fixed on the left support rod, the middle support rod and the right support rod of the web board, and the elastic web board connects the left support rod, the middle support rod and the right support rod of the web board into one, thereby constituting a bionic flexible paddy field row-to-row driven weeding unit.

[0005] The invention is based on the structural characteristics of the webbed claws of livestock and poultry, and is designed into a paddy field inter-row driven weeding unit using the bionic principle. Under the control of the left and right torsion springs for adjusting the opening of the web plate, the elastic web plate is elastically deformed and shaken by the cooperation of the left and right support rods of the web plate and the support rod in the web plate, so as to complete the removal of soil adhered to the weeding component. At the same time, the web plate return torsion spring can drive the elastic web plate to swing back and forth quickly in the circumferential direction of the spoke plate through the rod seat, thereby improving the technical effect of the weeding component in removing adhered soil. The invention has the characteristics of scientific principle, novel, unique and reasonable structure, good weeding effect, high working efficiency and low power consumption.

The web plate return pin shaft 7-11 and the limit pin 7-13 are equal in number to the cylindrical seat 7-18, and the web plate return torsion spring 7-12 is sleeved on the web plate return pin shaft 7-11, and the two ends of the web plate return torsion spring 7-12 are respectively in extrusion contact with the rod seat 7-2 and the limit pin 7-13; the web plate left support rod 7-7, the web plate middle support rod 7-6, and the web plate right support rod 7-5 are respectively hinged and installed on the rod seat 7-2 in sequence so as to be reciprocatingly swingable through the left support rod shaft 7-15, the middle support rod shaft 7-16, and the right support rod shaft 7-17, and the left pin shaft 7-8 and the right pin shaft 7-4 are fixed on the rod seat 7-2, and the web plate opening adjustment left torsion spring 7 —10 and the right torsion spring 7-3 for adjusting the web opening are respectively mounted on the left pin 7-8 and the right pin 7-4, and the two ends of the left torsion spring 7-10 for adjusting the web opening are respectively in extrusion contact with the web middle support rod 7-6 and the web left support rod 7-7, and the two ends of the right torsion spring 7-3 for adjusting the web opening are respectively in extrusion contact with the web middle support rod 7-6 and the web right support rod 7-5, and an elastic web 7-9 is fixed on the web left support rod 7-7, the web middle support rod 7-6 and the web right support rod 7-5, and the elastic web 7-9 connects the web left support rod 7-7, the web middle support rod 7-6 and the web right support rod 7-5 into one.

[0014] When in operation, the bionic flexible paddy field inter-row driven weeding unit is mounted on the paddy field inter-row weeding machine and moves forward with the machine. The external rotational power drives the bionic flexible weeding wheel 7 to actively rotate through the driving sprocket 2, the driving main shaft 1, the driving bevel gear 4, the driven bevel gear 6, and the driving half shaft 5, and the active rotation movement of the elastic webs 7-9 is used to perform paddy field inter-row weeding operations. During the operation, under the action of the resistance of the paddy field mud, the elastic web 7-9 is bent and deformed in an arc shape. At this time, the left web support rod 7-7 and the middle web support rod 7-6 and the right web support rod 7-5 and the middle web support rod 7-6 respectively increase the torsion of the web opening adjustment left torsion spring 7-10 and the web opening adjustment right torsion spring 7-3. When the elastic web 7-9 is out of contact with the paddy field mud, under the action of the torsion of the left and right torsion springs 7-10 and 7-3 for adjusting the web opening, the elastic web 7-9 is quickly restored to a planar state through the left and right web support rods 7-7 and 7-5, and its elastic shaking force removes the mud adhering to the elastic web 7-9. At the same time, when the elastic web 7-9 is subjected to the resistance of the paddy field mud, the rod seat 7-2 rotates counterclockwise relative to the spoke 7-1 on the barrel seat 7-18 around the latch 7-14. At this time, the web return torsion spring 7-12 is squeezed by the torsion force and the torsion increases. When the elastic web 7-9 is out of contact with the paddy field mud, under the torsion of the web return torsion spring 7-12 with increased torsion, the elastic web 7-9 quickly completes the clockwise return rotation relative to the spoke 7-1, and its shaking vibration increases the ability to remove the mud adhered to the elastic web 7-9, so as to achieve better operation quality and effect. The upward inclination angle β between the axis of the barrel seat 7-18 and the vertical line of the spoke 7-1 is the same as the downward inclination angle α between the axis of the drive half shaft 5 and the axis of the drive main shaft 1, which ensures that the elastic web 7-9 enters the mud symmetrically on both sides to ensure the effect of weeding between rows.
