Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a device for adjusting furrows on both sides of a rice transplanter. Background Art

[0002] With the development and application of various advanced technologies, mechanization has gradually been realized in the rice planting process. Rice transplanter is an important machine in the rice planting process. During the operation, rice seedlings are transplanted through the grooves opened by the furrow opener. The efficiency and results of transplanting are directly related to the grooves.

[0003] At present, a Chinese invention with the announcement number of CN210959428U discloses a synchronous furrowing device for rice transplanting on a rice transplanter, which relates to a furrowing device for opening furrows in the middle after rice transplanting. Although the device can adjust the height of the furrow opener, it does not have a buffering effect on the furrow opener, resulting in the furrow opener being easily deformed when encountering hard objects;

[0004] Moreover, most of the current furrow openers are fixedly mounted on the floating plate, and when the furrow opener is damaged and needs to be replaced, it is inconvenient to disassemble it. Summary of the invention

[0005] The invention aims at providing a furrowing adjustment device on both sides of a rice transplanter, which has the advantages of being convenient for buffering the furrow opener and facilitating the disassembly, assembly and replacement of the furrow opener.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a furrowing adjustment device on both sides of a rice transplanter, comprising a connecting beam, a furrow opener is arranged below the connecting beam, the top of the furrow opener is fixedly connected to a connecting column, a fixing column is slidably connected inside the connecting column, the top of the fixing column is fixedly connected to the top of the inner cavity of the connecting beam, a first spring is arranged on the outside of the fixing column, a buffer mechanism is arranged inside the connecting column, a positioning groove is arranged on the top of the furrow opener, a limiting groove is arranged on the inner wall of the positioning groove, a positioning block is fixedly connected to the bottom of the connecting column, a limiting ear plate is fixedly connected to one side of the positioning block, and a fixing screw is threadedly connected to the inner wall of the limiting ear plate.

[0007] The above technical solution is adopted: when the furrow opener encounters a hard object, it drives the connecting column to move along the fixed column, thereby compressing the first spring. At this time, the connecting block moves in the buffer chamber and squeezes the buffer solution. Part of the buffer solution flows through the through hole to the top of the connecting block under the action of pressure. The furrow opener is buffered by the first spring and the buffer solution to prevent it from being deformed or damaged: when the furrow opener needs to be replaced, the fixing screw is removed from the limiting ear plate, and then the furrow opener is moved downward to make the limiting ear plate disengage from the limiting groove, and the arc-shaped fixed block moves into the cavity and disengages from the arc-shaped fixed groove, and then the furrow opener continues to be moved downward to make the positioning block disengage from the positioning groove, thereby completing the disassembly of the furrow opener, and the reverse operation can be used to install and fix it.

[0008] The present invention is further configured as follows: the buffer mechanism comprises a buffer chamber opened in the inner cavity of the connecting column, and the bottom end of the fixing column is located in the buffer chamber.

[0009] The above technical solution is adopted to facilitate the movement of the connecting column along the fixed column.

[0010] The present invention is further configured such that the buffer mechanism further comprises a connecting block fixed to the bottom of the fixing column, and a through hole is formed on an inner wall of the connecting block.

[0011] By adopting the above technical solution, the buffer solution can be decompressed.

[0012] The present invention is further configured such that a buffer solution is provided in the buffer chamber, and the buffer solution is located below the connecting block.

[0013] Adopting the above technical solution: it is convenient to buffer the furrow opener.

[0014] The present invention is further configured such that a slider is fixedly connected to the outer side of the connecting column, the number of the slider is two, and the two sliders are symmetrically arranged.

[0015] The present invention is further configured such that an inner wall of the connecting beam is provided with a sliding groove for use with a sliding block.

[0016] The above technical solution is adopted to facilitate the stable movement of the connecting column.

[0017] The present invention is further configured such that an arc-shaped fixing groove is provided on the inner wall of the positioning groove.

[0018] Adopting the above technical solution: it is convenient to limit the furrow opener.

[0019] The present invention is further configured such that a cavity is formed on the inner wall of the positioning block, and an arc-shaped fixing block is slidably connected to the inner wall of the cavity.

[0020] The above technical solution is adopted to facilitate storage of the arc-shaped fixing block.

[0021] The present invention is further configured such that a guide rod is fixedly connected to one side of the arc-shaped fixed block, a second spring is arranged on the outer side of the guide rod, one end of the second spring is fixedly connected to the inner wall of the positioning block, and the other end of the second spring is fixedly connected to one side of the arc-shaped fixed block.

[0022] The above technical solution is adopted to facilitate automatic resetting of the arc-shaped fixing block.

[0023] The present invention is further configured such that the inner wall of the positioning block is provided with a guide groove for use in conjunction with the guide rod.

[0024] By adopting the above technical solution, the arc-shaped fixed block can remain stable when moving.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1: When the furrow opener encounters a hard object, it drives the connecting column to move along the fixed column, thereby compressing the first spring. At this time, the connecting block moves in the buffer chamber and squeezes the buffer. Under the action of pressure, part of the buffer flows through the through hole to the top of the connecting block, and the furrow opener is buffered by the first spring and the buffer to prevent it from deformation or damage.

[0027] 2: When the furrow opener needs to be replaced, remove the fixing screw from the limiting ear plate, then move the furrow opener downward to disengage the limiting ear plate from the limiting groove, and move the arc-shaped fixing block into the cavity and disengage the arc-shaped fixing groove. Then continue to move the furrow opener downward to disengage the positioning block from the positioning groove, thereby completing the disassembly of the furrow opener. The reverse operation can be performed to install and fix it. BRIEF DESCRIPTION OF THE DRAWINGS
