Description

Technical Field

[0001] This utility model belongs to agricultural machinery, and mainly relates to a ball cage type single unit suitable for simultaneous weeding and loosening of soil on both sides of the ridge. Background Technology

[0002] Ridge planting is a dryland farming technique adapted to cold regions. Due to its many advantages, such as wind protection, increased soil temperature, moisture retention, and reduced soil erosion, this method has been widely used in regions such as Heilongjiang and Jilin in Northeast my country.

[0003] In recent years, in order to ensure and improve the quality of agricultural products and reduce chemical residues, and with the introduction of the "three reductions" requirement (reducing the use of chemical fertilizers, chemical pesticides, and chemical herbicides) in my country, many high-tech weeding methods such as flame weeding and laser weeding have begun to be developed. However, they are still in the research and testing stage, and are not only technically immature and costly, but also cannot guarantee the quality and effectiveness of the operation. Under these circumstances, traditional mechanical weeding and soil loosening equipment has been put back on the research and development agenda. Traditional mechanical weeding equipment used for ridge planting uses a weeding and hoeing component to weed and loosen the soil on both sides of the ridge. In recent years, a trapezoidal weeding toothed disc roller composed of multiple weeding toothed discs connected in series according to the shape of the ridge has been used in practice. However, due to deficiencies and shortcomings in structural design, the above-mentioned ridge weeding and soil loosening components cannot be adjusted in position according to different changes in ridge shape, ridge side shape, and size, resulting in poor adaptability and unreliable weeding and soil loosening quality and operation effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and problems of the existing technology, and to develop and design a new type of ball cage-type double-sided ridge weeding and soil loosening unit based on the current actual needs for mechanized weeding and soil loosening operations. This unit aims to achieve strong adaptability, high operating efficiency, good quality weeding and soil loosening operations, and simple, convenient, and quick adjustment and operation.

[0005] The basic design of this utility model is as follows: A front axle sleeve and a rear axle sleeve are coaxially fixed on the lower middle part of the longitudinal single beam, from front to back. A pin is axially and radially positioned and circumferentially rotatably supported and inserted into the sleeve holes of the front and rear axle sleeves. A left crossbeam is fixed on the front end of the pin, located on the outer left side of the longitudinal single beam. A front clamping plate is axially adjustable via a U-shaped clip B on the left crossbeam. A ball-cage type weeding and soil loosening device is fixed on the front clamping plate, movable vertically and circumferentially via a U-shaped clip A. An L-shaped limiting plate A is fixed on the right end of the left crossbeam. A limiting screw A is axially adjustable and inserted into the L-shaped limiting plate A, and is in contact with or disengaged from the right vertical wall of the longitudinal single beam. A right crossbeam is fixed on the rear end of the pin, located on the outer right side of the longitudinal single beam. A rear clamping plate is axially adjustable via a U-shaped clip D on the right crossbeam. A cage-type weeding and soil loosening device for ridges is mounted on the rear clamp plate, which can move up and down and rotate circumferentially via a U-shaped clip C. An L-shaped limiting plate B is fixedly mounted on the left end of the right crossbeam. The limiting screw B is axially adjustable and inserted into the L-shaped limiting plate B, and is in contact with or out of contact with the left side wall of the longitudinal single beam. The structure of the cage-type weeding and soil loosening device is as follows: a fixed base plate that is inclined downwards is mounted on the lower end of the mounting column. The cage column is fixed on the base plate by a nut. A rack-shaped circular base plate is rotatably mounted on the lower side of the cage column, located below the base plate. N arc-shaped weeding and soil loosening racks are evenly distributed and fixed along the circumferential direction on the lower part of the outer edge of the rack-shaped circular base plate. The bottom end of the N arc-shaped weeding and soil loosening racks is generally in the shape of a circular through hole. A circular support plate is fixed on the inner side of the N arc-shaped weeding and soil loosening racks. This constitutes a cage-type double-sided ridge weeding and soil loosening unit.

[0006] This utility model features a ball-cage type ridge weeder and soil loosener mounted on the left and right sides of the longitudinal single beam frame. It can be adjusted laterally, vertically, and circumferentially. This enables simultaneous weeding and soil loosening on both sides of ridges of various shapes and sizes. It has the characteristics of novel, unique, and reasonable structure, strong adaptability, wide application range, simple, convenient, and quick adjustment and operation, high work efficiency, good weeding quality, reliable use, and few operation failures.

[0014] The following is a detailed description of the embodiments of this utility model with reference to the accompanying drawings. A ball-cage type double-sided ridge weeding and soil-loosening unit has a parallel four-bar linkage 2 and a ground wheel 4 respectively installed on the upper and lower front sides of the longitudinal unit beam 1. A front axle sleeve 8 and a rear axle sleeve 10 are coaxially fixed from front to back on the lower middle part of the longitudinal unit beam 1. A pin 9 is axially and radially positioned and circumferentially rotatable, inserted into the holes of the front axle sleeve 8 and the rear axle sleeve 10. A left crossbeam 7 is fixed on the front end of the pin 9, located on the outer left side of the longitudinal unit beam 1. The left crossbeam 7 can be axially reciprocated and adjusted via a U-shaped clip B6. The front clamping plate 5 is equipped with a clamping ball cage type weeding and soil loosening device 17 that can move up and down and rotate circumferentially on the front clamping plate 5 via U-shaped clamps A3. An L-shaped limiting plate A18 is fixed on the right end of the left crossbeam 7. A limiting screw A19 is axially adjustable and inserted into the L-shaped limiting plate A18, and is in contact or disengaged from the right vertical wall of the longitudinal single beam 1. A right crossbeam 13 is fixed on the rear end of the pin shaft 9, located on the outside of the right side of the longitudinal single beam 1. The right crossbeam 13 can be axially reciprocated via U-shaped clamps D11. The adjustable clamping rear plate 12, on which a clamping ball cage type ridge weeder and soil loosener 17 can be moved up and down and rotated circumferentially via a U-shaped clip C14, has an L-shaped limiting plate B16 fixedly mounted on the left end of the right crossbeam 13. The limiting screw B15 is axially adjustable and inserted into the L-shaped limiting plate B16, and is in contact with or not in contact with the left vertical wall of the longitudinal single beam 1. The structure of the ball cage type ridge weeder and soil loosener 17 is as follows: a fixed base plate 17-2 that is inclined downwards is mounted on the lower end of the mounting column 17-1. Cage column 17-3 is fixed on the base plate 17-2 by nuts 17-7. A rack-shaped circular base plate 17-4 is rotatably installed on the lower side of the cage column 17-3, below the base plate 17-2. N arc-shaped weeding and loosening racks 17-5 are evenly distributed and fixed along the circumference on the lower part of the outer edge of the rack-shaped circular base plate 17-4. The bottom of the N arc-shaped weeding and loosening racks 17-5 is a circular through hole. A circular support plate 17-6 is fixed on the inner side of the N arc-shaped weeding and loosening racks 17-5.

[0015] During operation, the entire unit is mounted on the frame of the mechanical tillage, weeding, and soil loosening machine using the parallel four-bar linkage 2. It floats and moves forward randomly, following the contours of the machine. The ball cage-type ridge weeding and soil loosening devices 17 on the left crossbeam 7 and right crossbeam 13 are located on the left and right sides of the same ridge, respectively. The lower arc-shaped parts of the N inclined arc-shaped weeding and soil loosening racks 17-5 contact and cooperate with the soil on the ridge side in sequence. Under the action of soil resistance, the arc-shaped weeding and soil loosening racks 17-5 and the rack circular seat plate 17-4 rotate together on the cage column 17-3 to perform and complete the synchronous weeding and soil loosening operation on both sides of the ridge. During operation, the bottom ends of the N arc-shaped weeding and loosening teeth 17-5 are generally circular through-hole structures, which not only prevents soil from depositing in the ball cage type weeding and loosening device 17, but also increases the repeated impact and crushing ability of the soil by the elastic deformation reciprocating motion of the lower end of each arc-shaped weeding and loosening tooth 17-5 under the resistance of the soil on the ridge, thus ensuring and improving the weeding and loosening operation effect and reducing the occurrence of operation failures.

[0016] The limiting screw A19 contacts the right vertical side of the longitudinal single beam 1, controlling the lowest point of the ball cage type weeding and soil loosening device 17 on the lower part of the left crossbeam 7 through the left crossbeam 7. At the same time, the pin 9 and the right crossbeam 13 simultaneously limit the highest point of the ball cage type weeding and soil loosening device 17 on the lower part of the right crossbeam 13. The limiting screw B15 contacts the left vertical side of the longitudinal single beam 1, controlling the lowest point of the ball cage type weeding and soil loosening device 17 on the lower part of the right crossbeam 13 through the right crossbeam 13. At the same time, the pin 9 and the left crossbeam 7 simultaneously limit the highest point of the ball cage type weeding and soil loosening device 17 on the lower part of the left crossbeam 7.
