Description

Paddy field inter-row same-direction differential rotary cutting combined weeding monomer

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a paddy field interline weeding operation assembly.

Background

At present, the intertillage weeding operation in paddy fields mostly adopts the cage weeding roller of single structure to undertake and accomplish, and based on the characteristics that the overall structure of the cage weeding roller is simple, the manufacturing cost is low, and the installation is simple and convenient on the intertillage weeding machine, the weeding roller is continuously used up to now. However, in the practice of production operation, the cage type weeding roller rotates with the following rotation of the cage type weeding roller due to the soil resistance, so that the disturbance to the soil between rows of the paddy field is small, the weeding rate is low, the weeding quality is poor, and the whole operation quality is not high.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and combines the actual requirements of intertillage weeding operation in paddy fields to research and develop a paddy field intertillage equidirectional differential rotary-cut combined weeding monomer.

The purpose of the invention is realized as follows: triangular star-shaped frames are symmetrically and respectively fixed on two opposite side parts of the single frame, the upper end parts of two triangular star frames which are oppositely configured are respectively and rotatably provided with a positioning support planetary gear, the planet gear shaft A and the planet gear shaft B are respectively and rotatably arranged on the front side and the rear side of the lower end of the two triangular star frames which are oppositely arranged, the central parts of two triangular star frames which are oppositely arranged are respectively and rotatably provided with a sun gear, the sun gear is meshed with the planet gears of the planet gear shaft A and the planet gear shaft B and the positioning support planet gear, inner gear rings are arranged on the outer sides of the positioning support planetary gears, the planetary gear shafts A and the planetary gear shafts B in a mutually meshed matched manner, and the cage type weeding roller is fixedly sleeved on the outer portions of the inner gear rings to form a whole; the blade type weeding roller A and the blade type weeding roller B are fixedly supported and arranged between the planetary gear shaft A and the planetary gear shaft B which are arranged oppositely, the planetary gear shaft A and the planetary gear shaft B are arranged in an axially crossed and staggered mode, the rotating directions are the same, and therefore the same-direction differential rotary cutting combined weeding unit among rows of the paddy field is formed.

The invention creates the mode that the blade type weeding roller A and the blade type weeding roller B are respectively assembled in the cage type weeding roller, the planetary gear train transmission structure is adopted to transmit the rotation power of the cage type weeding roller to the blade type weeding roller A and the blade type weeding roller B to enable the blade type weeding roller A and the blade type weeding roller B to rotate in the same direction and in a differential way, the combined compound operation of intertillage weeding, grass smashing and soil loosening of weeding monomers is completed and realized, and the invention has the characteristics of novel, unique, reasonable and compact structure, good operation quality, high efficiency, strong adaptability and reliable use.

Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A paddy field interline equidirectional differential rotary-cut combined weeding unit comprises a cage type weeding roller 7, triangular star-shaped frames 2 are fixedly arranged on two opposite side parts of a unit frame 1 symmetrically and respectively, positioning support planetary gears 10 are rotatably arranged on the upper end parts of the two triangular star-shaped frames 2 which are oppositely arranged respectively, planetary gear shafts A4 and planetary gear shafts B5 are rotatably arranged on the front side parts and the rear side parts of the lower ends of the two triangular star-shaped frames 2 which are oppositely arranged respectively, sun gears 3 are rotatably arranged on the central parts of the two triangular star-shaped frames 2 which are oppositely arranged respectively, the sun gears 3 are meshed with the planetary gear shafts A4 and planetary gears of the planetary gear shafts B5 and the positioning support planetary gears 10, inner gear rings 6 are arranged on the outer side parts of the positioning support planetary gears 10, the planetary gear shafts A4 and the planetary gear shafts B5 in a mutually meshed matching manner, the cage type weeding roller 7 is fixedly sleeved on the outer part of the inner gear ring 6 to form a whole; the blade type weeding roller A8 and the blade type weeding roller B9 are fixedly supported between the two pairs of planet gear shafts A4 and planet gear shafts B5 which are oppositely arranged, and the blade type weeding roller A8 and the blade type weeding roller B9 are axially arranged in a crossed and staggered mode and have the same rotating direction.

When the weeding machine is used, the single frame 1 is utilized to integrally assemble the weeding machine on a cultivation weeding machine, the cage-type weeding roller 7 is arranged in soil at the inter-row position of a paddy field and moves forwards along with the whole machine, the cage-type weeding roller 7 is pushed to rotate under the action of soil resistance, the rotating motion of the cage-type weeding roller 7 sequentially drives the blade-type weeding roller A8 and the blade-type weeding roller B9 to rotate at high speed through the inner gear ring 6, the planet gear shaft A4, the planet gear shaft B5 and the sun gear shaft 3 respectively, the rotating directions of the blade-type weeding roller A8 and the blade-type weeding roller B9 are the same as the rotating direction of the cage-type weeding roller 7, and the cage-type weeding roller 7, the blade-type weeding roller A8 and the blade-type weeding roller B9 sequentially and respectively perform weeding, weed removal, soil disturbance and soil loosening operation. The blade type weed removing roller A8 and the blade type weed removing roller B9 can perform high-speed cutting, beating, smashing and throwing operations on the soil after the operation of the cage type weed removing roller 7, so that the quality of soil intertillage operation is improved, weeds are cut, grass seeds carried in the soil can be beaten out to lose growth conditions, and the weed removing operation effect is guaranteed.
