Description

Technical Field

[0001] The invention belongs to the field of rice transplanter equipment, and in particular relates to a wire pulling and releasing structure of a rice transplanter marking device. Background Art

[0002] Rice transplanters are planting machines that plant rice seedlings in paddy fields. There are different types of rice transplanters. According to the state of the seedlings, they are divided into the type of pulling and washing seedlings, the type of seedlings with soil, and the dual-purpose type; according to the power, they are divided into two types: manual transplanters and motorized transplanters; according to the movement characteristics of the seedling separation and transplanting mechanisms, they can be divided into longitudinal rolling direct transplanting, longitudinal swing direct transplanting, and transverse swing direct transplanting; rice transplanters can be divided into walking rice transplanters, motorized rice transplanters, and high-speed rice transplanters. The composition of the planting parts of various transplanters is basically the same. The manual transplanter is composed of a seedling box, a seedling separation and transplanting mechanism, a frame, and a float, etc. The self-propelled motorized transplanter is also equipped with power drive, walking device, and seedling delivery mechanism. The basic working principle of the rice transplanter: the seedlings are placed neatly in the seedling box in a group state, and move horizontally with the seedling box, so that the seedling taker can take a certain number of seedlings one by one. Under the action of the transplanting trajectory control mechanism, the seedlings are inserted into the soil according to agronomic requirements, and the seedling taker then returns to the seedling box along a certain trajectory to take the seedlings.

[0003] In order to make the seedlings planted more regularly, the existing transplanters are generally equipped with a marking device, and the marking device is put down when traveling and collected when transplanting. The current retractable structure of the transplanter is complicated and difficult to operate. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a wire pulling and releasing structure of a wire marker of a rice transplanter, which has a simple structure and is easy to operate.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A wire pulling and releasing structure of a wire marking device for a rice transplanter comprises an operating handle, a second positioning plate, a pulling plate, a limit hook plate, a pulling wire transmission plate, a hydraulic cylinder, a seedling stand frame and a control valve, wherein the second positioning plate is rotatably arranged on a vehicle frame, the operating handle is rotatably arranged on one side of the second positioning plate, the operating handle is L-shaped, and a handle is fixed at one end, and a bent hook is formed at the other end, the pulling plate is slidably arranged on the vehicle frame, a first notch and a second notch are respectively arranged at both ends of the pulling plate, the bent hook of the operating handle is clamped in the first notch of the pulling plate, driving the pulling plate to slide, and the two side walls of the second notch of the pulling plate are respectively engaged with two limit hooks The side walls of the plate are abutted against each other, and the limit hook plate is set on the frame through a short axis rotation. A hook portion is provided at one end of the limit hook plate, and a wire transmission plate connected to the scriber wire is hinged on the frame and set in a sliding groove of the frame. The hook portion of the limit hook plate is abutted against the wire transmission plate, and a reset column is also fixed to the lower part of the wire transmission plate. The control valve is fixed on the frame and connected to the hydraulic cylinder through a pipeline. The piston rod of the hydraulic cylinder is connected to the seedling stand frame, and a reset cross bar is provided on the seedling stand frame. When the seedling stand frame rises, the reset cross bar pushes the reset column, so that the wire transmission plate is clamped by the limit hook plate again when it retreats.

[0007] As a preferred solution: the second positioning plate is fan-shaped as a whole, and the arc edge is serrated. The operating handle can simultaneously drive the second positioning plate to move, and the serrated arc edge of the second positioning plate is more conducive to the positioning of the operating handle.

[0008] As a preferred solution, the side of the hook portion of the limit hook plate away from the wire pulling transmission plate is a guide arc surface. The guide arc surface facilitates the limit hook plate to be pushed away when the wire pulling transmission plate returns to its original position, and the movement process is smoother.

[0009] The present invention drives the pull plate to slide by operating the hand lever, and then drives the limit hook plate to release the pull wire transmission plate, thereby realizing the release of the marker, and pushes the pull wire transmission plate to be clamped by the limit hook plate again through the movement of the seedling stand frame. The overall structure is simple, the operation is reliable, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0015] like Figures 1 to 4 As shown, the present invention provides a wire pulling and releasing structure of a wire marking device for a rice transplanter, comprising an operating handle 1401, a second positioning plate 1411, a pulling plate 1402, a limit hook plate 1403, a wire pulling transmission plate 1404, a hydraulic cylinder 1406, a seedling stand frame 1407 and a control valve 1410, wherein the second positioning plate 1411 is rotatably arranged on the vehicle frame 2, the operating handle 1401 is rotatably arranged on one side of the second positioning plate 1411, the operating handle 1401 is L-shaped, and a handle is fixed at one end, and a bent hook is formed at the other end, and the pulling plate 1402 is slidably arranged On the frame 2, a first notch and a second notch are respectively provided at both ends of the pull plate 1402. The bent hook of the operating handle 1401 is clamped in the first notch of the pull plate 1402, driving the pull plate 1402 to slide. The two side walls of the second notch of the pull plate 1402 are respectively against the side walls of two limiting hook plates 1403. The limiting hook plates 1403 are set on the frame 2 through short axis rotation. A hook portion is provided at one end of the limiting hook plate 1403. The wire transmission plate 1404 connected to the scriber wire is hinged on the frame 2 and is set in the sliding groove of the frame 2.

[0016] The hook portion of the limit hook plate 1403 is against the wire transmission plate 1404, and a reset column 1405 is also fixed to the lower part of the wire transmission plate 1404. The control valve 1410 is fixed on the frame 2 and connected to the hydraulic cylinder 1406 through the pipeline 1409. The piston rod of the hydraulic cylinder 1406 is connected to the seedling stand frame 1407, and a reset cross bar 1408 is provided on the seedling stand frame 1407. When the seedling stand frame 1407 rises, the reset cross bar 1408 pushes the reset column 1405, so that the wire transmission plate 1404 is again caught by the limit hook plate 1403 when it retreats.
