Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a weeding device. Background Art

[0002] At present, with the development of green agriculture and ecological agriculture, people gradually give up using herbicides and other drugs with chemical components for weeding, and often use weeders for weeding. In the prior art, a "multifunctional machine for weeding in rows" is disclosed, and the publication number is CN 111149454 A, which includes a frame, on which a plurality of transmission boxes arranged in the same row are arranged, and the transmission box is tilted backward and one end extending downward is rotatably connected to a transmission shaft, and in the left and right directions, both ends of the transmission shaft extend out of the transmission box, and the two ends of the transmission shaft extending out of the transmission box are respectively connected to a row weeding wheel, and a plurality of weeding blades are arranged on the periphery of the row weeding wheel. In this design, the row weeding wheel moves between rows, and the weeding blades rotate continuously to remove weeds between rows. This machine is suitable for weeding in dry fields, and the weeding effect in paddy fields is not good. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a weeding device to solve the technical problem of poor weeding effect in the prior art. The present invention works reliably and has good weeding effect.

[0004] The objective of the present invention is achieved as follows: a weeding device comprises a frame, on which are arranged a plurality of transmission boxes arranged in the same row, wherein one end of the transmission box which is inclined backward and extends downward is rotatably connected to a transmission shaft, and in the left and right directions, both ends of the transmission shaft extend out of the transmission box, and the two ends of the transmission shaft extending out of the transmission box are respectively connected to a weeding wheel, the outer periphery of the weeding wheel is provided with a rolling gear assembly, the rolling gear assembly comprises a plurality of weeding plates arranged on the outer periphery of the weeding wheel, one end of the weeding plate is fixed to the outside of the weeding wheel, and the other end of the weeding plate is arranged with a plurality of rolling gears, and a tooth groove is formed between two adjacent rolling gears, and a limiting frame is fixed to the rear end of the transmission box, and two sliding shovels are connected to the lower side of the limiting frame, and the positions of the two sliding shovels in the left and right directions correspond to the positions of the two weeding wheels on the transmission shaft.

The rotation direction of the weeding wheel is the same as the forward direction of the frame. The transmission box is rotatably connected to the connecting shaft; the transmission box moves, the transmission shaft rotates, and the rotation of the transmission shaft drives the rotation of the weeding wheel. The movement direction of the transmission box is controlled to make the rotation direction of the weeding wheel consistent with the forward direction of the frame. The weeding wheel drives the rotation of the weeding plate 1, and two adjacent hobs 1 pick out the weeds in the corresponding area out of the soil and throw the picked weeds backwards to achieve weeding. At the same time, the limit frame provides support for the weeding wheel and limits the weeding depth at the same time. It can be applied to inter-row weeding.

[0006] In order to improve the weeding effect, a gear rolling assembly 2 is also provided on the periphery of the weeding wheel, and the gear rolling assembly 2 includes a plurality of weeding plates 2 arranged on the periphery of the weeding wheel, a weeding plate 2 is arranged between two adjacent weeding plates 1, one end of the weeding plate 2 is fixed to the outside of the weeding wheel, and a plurality of gear rolling 2 is arranged on the other end of the weeding plate 2, and tooth grooves 2 are formed between adjacent gear rolling 2, and the tooth grooves 1 and 2 are staggered in the axial direction.

[0007] In order to further improve the weeding effect, at least one weeding component 1 is provided on the lower side of the sliding shovel, and the weeding component 1 includes a plurality of grass hooking teeth 1 arranged in the same row, and a grass shoveling space 1 is formed between the grass hooking teeth 1 and the downward side of the sliding shovel; in this design, the tooth groove 1 between two adjacent rolling teeth 1 and the tooth groove 2 between two adjacent rolling teeth 2 throw the grass together with the root backwards, and the grass hooking teeth 1 scoop up the grass thrown backwards to clean the roots of the grass. The grass floats in the paddy field and the roots cannot touch the ground. Through the combined arrangement of the weeding wheel, the rolling tooth assembly and the weeding component, the purpose of weeding is achieved, which is beneficial to the growth of crop seedlings.

[0008] As a further improvement of the present invention, the weeding component one is provided with two groups, and the two groups of weeding component one are arranged at intervals in the front-to-back direction.

[0009] In order to further avoid missing weeds, a weeding component 2 is also connected to the lower side of the slide between the two groups of the weeding components 1. The weeding component 2 includes a plurality of grass hook teeth 2 arranged in the same row. A grass-hoveling space 2 is formed between the grass hook teeth 2 and the downward side of the slide. In the left and right directions, a grass hook tooth 2 is provided between two adjacent grass hook teeth 1. In this design, the grass hook tooth 2 scoops up the grass between the two grass hook teeth 1 at the front and rear ends, so that the grass can be cleaned, thereby avoiding missing weeds and further improving the weeding effect.

[0010] In order to further realize the rotation of the weeding wheel, a driving box is fixedly connected to the front part of the frame, a driving shaft is connected to the driving box, one end of the driving shaft extending out of the driving box is connected to a driving wheel, a connecting shaft is connected to the frame behind the driving box, a driven wheel is connected to the connecting shaft, the driving wheel and the driven wheel are connected in transmission, and the power input of the transmission box is the connecting shaft.

[0011] In order to further improve the reliability of the rotation of the connecting shaft, a plurality of supporting seats are connected to the frame, and the connecting shaft is rotatably connected to the supporting seats.

[0012] As a further improvement of the present invention, the slide extending forward out of the limit frame is tilted upward, and the rear part of the slide is tilted upward; in this design, the front and rear ends of the slide are both tilted upward, and mud is not easy to accumulate on the slide, thereby reducing the sliding resistance of the slide.
