Description

Technical Field

[0001] The utility model relates to the technical field of weeders, in particular to a transverse movement mechanism of an intelligent weeder. Background Art

[0002] The intelligent weeder is a weeding equipment that integrates mechanical, electrical and hydraulic functions. It can cut and bury weeds in field crops. The transverse movement mechanism is a key component that can perform precise weeding operations in rows. It can ensure that the weeder can accurately and effectively remove weeds around crops, thereby preventing weeds from competing with crops for nutrients and water, and ensuring the healthy growth of crops.

[0003] The transverse movement mechanism can adjust the weeding frame to move left and right. The existing transverse movement mechanism is controlled by a one-way hydraulic cylinder. When weeding, due to uneven terrain or changes in the position of planted crops, row adjustments are required. The single hydraulic cylinder has a slow adjustment speed and certain limitations, which affects the efficiency and quality of weeding operations.

[0004] In view of the above situation, a double hydraulic cylinder transverse movement mechanism is proposed, and a displacement potentiometer is added to control the distance to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art. During the process of planting field crops with mechanical equipment, the position of the crop row often changes due to the influence of comprehensive factors such as the tractor's walking route and the error of the mechanical equipment. If the weeder always works in a straight line, it may damage the crops. At present, a single hydraulic cylinder is used to change the position of the agricultural machinery equipment during the farming process to adapt to the change of the position of the crop row. The operation efficiency is not accurate and efficient enough. Weeding is a job that requires refinement. Therefore, a double hydraulic cylinder lateral movement mechanism is added to the mechanical weeder, the double hydraulic cylinders move synchronously, and the displacement potentiometer is used to accurately control the lateral movement distance to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A transverse movement mechanism of an intelligent weeder comprises a frame, one side of the frame is connected to a towing device through a three-point suspension, a hydraulic control valve is installed at the front end of the frame, and ground wheels are installed on both sides of the frame. An upper slide groove and a lower slide groove are provided on the frame, and an upper slide rod and a lower slide rod are respectively provided in the upper slide groove and the lower slide groove, and the upper slide rod and the lower slide rod are connected by a transverse movement plate, and sliding holes are respectively provided on the upper and lower parts of the transverse movement plate, and the transverse movement plate is slidably connected to the upper slide rod and the lower slide rod through the sliding holes, and a positioning block is respectively provided on both sides of the transverse movement plate, and the positioning blocks are respectively connected to the right hydraulic cylinder and the left hydraulic cylinder, and the right hydraulic cylinder and the left hydraulic cylinder are respectively connected to the hydraulic control valve.

[0008] In a further embodiment, a mounting hole is provided in the slide groove on the frame, the mounting hole is fixedly connected to the end of the displacement potentiometer by a fastening bolt, the front end of the displacement potentiometer is connected to the transverse plate through a slide, and the displacement potentiometer is connected to the computer control system through a wire.

[0009] In a further embodiment, mounting holes are provided on both sides of the interior of the frame, and the rear ends of the left hydraulic cylinder and the right hydraulic cylinder are fixedly mounted on both sides of the interior of the frame through plunger plates.

[0010] In a further embodiment, mounting holes are provided on both sides of the lower end of the frame, and the ground wheels are fastened to both sides of the lower end of the frame by bolts.

[0011] In a further embodiment, a connecting rod is provided on one side of the transverse frame, the connecting rod is connected to the weeding machine frame, and is connected to the towing device through a three-point suspension.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is used, the lateral movement distance is calculated by the control system, and the electrical signal is transmitted to the hydraulic control valve, and the control signal is implemented to the hydraulic cylinder. The hydraulic cylinder drives the lateral movement plate, and the lateral movement plate slides left and right in the upper and lower slide grooves of the frame through control, thereby realizing the horizontal movement of the lateral movement plate relative to the frame.

[0014] When the utility model is used, the two hydraulic oil cylinders as power output have their cylinder bodies fixed to the frame through the plunger plate at the end and fixed to the transverse plate at the front end. The two transverse hydraulic oil cylinders are in a synchronous motion state during the working process. When the hydraulic rod of one hydraulic cylinder is extended, the hydraulic rod of the other hydraulic cylinder is retracted. The displacement potentiometer is connected to the transverse plate. With the extension and retraction of the hydraulic rod, the displacement potentiometer also moves synchronously, and the digital signal is fed back to the computer system at the same time, so that the computer can analyze the real-time transverse state and send corresponding control signals.
