The upper part of the rice transplanter connecting frame is rotatably connected to one end of an electric push rod device, and the other end of the electric push rod device is rotatably connected to a furrow opener; the lower part of the rice transplanter connecting frame is rotatably connected to the upper part of a limiting plate, and the lower part of the limiting plate is rotatably connected to the furrow opener. The lower end of the limiting plate has a sawtooth-shaped limiting structure, and the limiting structure abuts against the end of the furrow opener to limit the fixed angle formed between the furrow opener and the limiting plate; the extension and contraction of the electric push rod device drives the furrow opener and the limiting plate to rotate around the hinge axis with the rice transplanter connecting frame. The present invention cooperates with the working state of the electric push rod and the limiting plate to ensure that the furrow opener is always at an angle of about 20° with the horizontal plane to prevent grass from hanging; the limiting plate and the furrow opener are only provided with a bolt connection part, which is convenient for disassembly and assembly, and the furrow opener is limited by the sawtooth structure at the bottom of the limiting plate, and the design is ingenious.

Description

Technical Field

[0001] The invention relates to a furrowing device for furrowing water in the middle after transplanting rice seedlings, in particular to a rice transplanting synchronous furrowing device used on a rice transplanter. Background Art

[0002] After rice seedlings are transplanted, a ditch needs to be opened beside the transplanted rice seedlings for drainage in the later stage. In the prior art, the transplanting and ditching processes are usually carried out separately. The transplanter first completes the transplanting, and then the ditching equipment is used to dig the ditch, which makes the overall process of transplanting and ditching more complicated and inefficient.

[0003] The angle between the furrow opener and the horizontal plane is often an important factor affecting the grass hanging on the furrow opener and the furrow opening depth. The existing technology generally uses manual adjustment to adjust the furrow opening depth of the furrow opener, which has high labor intensity and also affects the work efficiency of furrow opening.

[0004] Therefore, how to combine a rice transplanter with a furrow opener for digging furrows and realize automatic adjustment of the angle between the furrow opener and the horizontal plane is a technical problem to be solved urgently in this field. Summary of the invention

[0005] The purpose of the present invention is to provide a synchronous ditching device for rice transplanting on a rice transplanter, wherein the ditching device can directly connect a rice transplanter connecting frame to a planting mechanism of the rice transplanter through bolts; an electric push rod adjusts the ditching depth of the ditch opener and controls the retraction and extension of the ditch opener; and a limit plate limits the maximum ditching depth by adjusting the position state of the ditch opener. In conjunction with the working state of the electric push rod and the limit plate, it is ensured that the ditch opener is always at an angle of about 20° with the horizontal plane to prevent grass from hanging.

[0006] The present invention adopts the following technical solutions:

[0007] A rice transplanting synchronous furrowing device for a rice transplanter, comprising a rice transplanter connecting frame 1, a limiting plate 2, a furrow opener 3, and an electric push rod device 4; the upper portion of the rice transplanter connecting frame 1 is rotatably connected to one end of the electric push rod device 4, and the other end of the electric push rod device 4 is rotatably connected to the furrow opener 3; the lower portion of the rice transplanter connecting frame 1 is rotatably connected to the upper portion of the limiting plate 2, and the lower portion of the limiting plate 2 is rotatably connected to the furrow opener 3, and the lower end of the limiting plate 2 has a serrated limiting structure, which abuts against the end of the furrow opener 3 to limit the fixed angle formed between the furrow opener 3 and the limiting plate 2; the extension and retraction of the electric push rod device 4 drives the furrow opener 3 and the limiting plate 2 to rotate together around the hinge axis with the rice transplanter connecting frame 1.

[0008] Preferably, the opening of the furrow opener 3 gradually decreases from the front end to the rear end, and the tail portion forms a portion that is tightly attached to the clamping limit plate 2.

[0009] Preferably, a vertical pole extends vertically upward in the furrow opener 3, and the upper end of the vertical pole is rotatably connected to the electric push rod device 4.

[0010] Furthermore, a pair of ear plates are provided at the upper end of the vertical rod, and the electric push rod device 4 is rotatably connected to the pair of ear plates.

[0011] Furthermore, the back of the rice transplanter connecting frame 1 is provided with a connecting hole for connecting and fixing with the rice transplanter.

[0012] Furthermore, the electric push rod device 4 controls the furrowing depth of the furrow opener 3 to be in the range of 12-18 cm.

[0013] Furthermore, the electric push rod device 4 controls the angle between the furrow opener 3 and the ground to be 20°. When furrowing is not needed, the furrow opener 3 is retracted by the electric push rod device.

[0014] The beneficial effects of the present invention are:

[0015] 1) The water channel opening device can directly connect the rice transplanter connecting frame to the planting mechanism of the rice transplanter by means of bolts;

[0016] 2) The electric push rod adjusts the furrowing depth of the furrow opener and controls the retraction and extension of the furrow opener;

[0017] 3) The limit plate limits the maximum trenching depth by adjusting the position of the trench opener. In conjunction with the working state of the electric push rod and the limit plate, ensure that the trench opener is always at an angle of about 20° to the horizontal plane to prevent grass from hanging.

[0018] 4) The limit plate and the furrow opener are connected by only one bolt connection part, which is convenient for disassembly and assembly. At the same time, the furrow opener is limited by the serrated structure at the bottom of the limit plate, so that the furrow opener and the limit plate form a similar part, which is ingeniously designed.
