Then, the hydraulic oil cylinder contracts, the long-stroke hydraulic oil cylinder extends out again, the line changing process is completed, meanwhile, the direction of the intertillage weeding rake wheel array is changed, in the process, rolling of rice seedlings caused by wheel steering is avoided, and damage to the seedlings is reduced. The device can adopt a remote control operation or automatic driving mode, and manual driving is not needed.

Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a remote-controlled translational and row-changing reciprocating paddy field tillage and weeding machine. Background Art

[0002] Weeding can effectively remove weeds in rice fields and reduce the competition of weeds for rice nutrients, thereby increasing the growth rate and yield of rice. However, long-term use of manual chemical weeding can lead to weed resistance and cause environmental pollution. Mechanical weeding, as an environmentally friendly alternative, can reduce the use of chemical herbicides and protect the paddy field environment.

[0003] At present, most weeding and cultivating machines need to be directly driven by humans and need to turn when changing rows. During the turning process, the wheels will crush the rice seedlings at the edge of the field, making it impossible to effectively utilize the land at the edge of the field, affecting rice yields and increasing planting costs. Summary of the invention

[0082] Working principle of the present invention:

[0083] See also Figures 1 to 5 The remote control translational reciprocating paddy field tillage weeding machine of the present invention works as follows. The motor (3) rotates to drive the entire device forward. During the movement, the weeding wheel (19) at the front rotates passively, so that the rake teeth can effectively pull up the weeds by the roots, thereby achieving the purpose of efficient weeding. At the same time, the weed pressing wheel (15) at the rear also rotates passively as the machine moves, compacting the remaining weeds into the soil, further ensuring a thorough weeding effect.

[0084] When the device moves to the edge of the paddy field and needs to change rows, the hydraulic cylinder (27) extends, the base (28) lifts the entire device, and the walking wheel (2) and the paddy field weeding harrow wheel (9) leave the paddy field soil surface. At this time, the long-stroke hydraulic cylinder (29) contracts, driving the frame (A) and the paddy field weeding harrow wheel array (B) to move horizontally to the side of the lateral moving mechanism (C), so that the frame (A) and the paddy field weeding harrow wheel array (B) are placed in the next tillage row. Subsequently, the hydraulic cylinder (27) contracts, the base (28) leaves the soil, and the walking wheel (2) contacts the paddy field soil. At this time, the long-stroke hydraulic cylinder (29) extends, driving the lateral moving mechanism (C) to move horizontally to the center position of the entire device. Finally, the paddy field weeding harrow wheel (9) is manually reversed through the turntable (10) and the tightening knob (25), completing the row change, and then continuing to weed.

[0085] During operation, the camera in the signal receiver (5) obtains information in front of the device and feeds it back to the operator. The operator sends instructions to the control box (6), and the control box (6) adjusts the speed of the motor (3), thereby adjusting the travel speed. In addition, the control box (6) can automatically control the frame (A) of the device and the paddy field weeding harrow wheel array (B) during the row-changing operation, without the need for manual frequent sending of control instructions.
