Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a furrow opener. Background Art
[0002] Furrow openers are commonly used parts in agriculture, mainly used to form planting furrows during sowing. Furrow openers mainly include chain type, disc type and moldboard plow, among which the moldboard plow is a farm tool for tilling land, which has the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standards of agricultural mechanized operations. Usually, the moldboard plow cannot adjust the width, and the opener needs to be replaced with the appropriate angle multiple times when facing different soil and seed types, which not only increases the purchase cost, but the replacement process also affects the operation efficiency. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a furrow opener with reasonable structural design, convenient operation and adjustment, which can reduce costs and improve working efficiency.

[0006] With the above structure, since the two plowboards are respectively hinged on the plow support, and a width adjustment mechanism that can adjust the distance between the connecting seat and the plow post is connected between the plowboard and the plow post, in the triangle formed by the width adjustment mechanism, the plowboard and the plow post, after the width adjustment mechanism changes the distance between the connecting seat and the plow post, the angle between the plowboard and the plow post also changes, so that the unfolded width of the two plowboards can be adjusted to meet different furrowing requirements.
[0007] Furthermore, the plow support and plow wall plate are made of plastic injection molding, and the plow column and plowshare are made of metal.
[0008] The plow post is made of metal as the supporting part of the furrow opener, which can ensure the stability of the working state such as the angle of the furrow opener. The plowshare is made of metal as the soil-breaking part, which can ensure the reliability of soil-breaking. The plow support and plow wall plate are plastic injection molding as the soil-turning parts after breaking the soil, which can not only ensure their working strength, but also plastic has good plasticity, and is not easy to deform compared to metal plow walls. In addition, plastic is not easily corroded by soil and has a longer service life. The injection-molded plow support and plow wall plate have lower costs and are easier to replace and repair later. In actual use, the existing metal plow wall plates are prone to soil adhesion, while the plastic plow wall plates do not adhere to the soil, which can achieve better soil turning effects and are easier to clean.
[0009] Furthermore, a support column is provided on the plow column, and the support column is located on the side of the plow column away from the plow support and on the symmetrical center plane of the plow support; the width adjustment mechanism is connected between the connecting seat and the support column.

[0011] In this way, by loosening the locking piece, the slider can be moved along the length of the support column, thereby changing the angle between the support rod and the support column, and then adjusting the opening size of the moldboard and changing the width of the furrow opener. After adjusting to the appropriate width, the slider is fixed to the support column through the locking piece, and the furrowing operation can be maintained at a fixed width.
[0012] Furthermore, the support column has a strip hole arranged along the length direction, the sliding block has a threaded hole arranged opposite to the strip hole, and the locking member is a locking bolt passing through the strip hole and connected to the threaded hole.
[0013] Furthermore, the support column has a guide groove arranged along the length direction, and the slider can be slidably engaged in the guide groove; the strip hole is located at the bottom of the guide groove, and the support rod has a hinge hole at one end facing the slider and can be rotatably sleeved on the locking piece.
[0014] In this way, after the locking piece is released, the locking piece and the slide block move together along the guide groove, and drive the support rod to swing, thereby controlling the rotation of the moldboard. After moving to a suitable position, the locking piece is rotated to fix the position of the support rod.
[0015] Furthermore, the support column is formed by bending a steel plate, and the guide groove is a U-shaped groove formed by bending.
[0016] Furthermore, a cross bar is hinged at the upper end of the plow column, and the cross bar is transversely arranged on the symmetrical center plane of the plow support; the front end of the cross bar has a connecting part for agricultural machinery, and a pitch adjustment mechanism is connected between the rear end and the plow column to adjust the distance between the two.
[0017] In this way, by adjusting the distance between the rear end of the cross bar and the plow column, the pitch angle of the plow column relative to the cross bar can be adjusted to meet different furrowing requirements.
[0018] Furthermore, a first hinge is hinged on the cross bar, and a second hinge is hinged on the side of the plow column away from the plow support. The first hinge has a threaded hole extending radially therethrough, and the second hinge has a through hole arranged radially. The pitch adjustment mechanism is a screw rod that fits on the threaded hole of the first hinge rod, one end of the screw rod can be relatively rotatably connected to the through hole of the second hinge shaft, and the other end is provided with a handle.
[0019] Furthermore, the plowshare includes two side plates arranged in a V-shape and a bottom plate connected to the bottom of the two side plates, and the upper ends of the side plates are connected to the plow support.
[0020] In summary, the utility model has the advantages of reasonable structural design, convenient operation and adjustment, and can reduce costs and improve working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

After moving to a suitable position, the locking piece is rotated to fix the position of the support rod.
[0032] In this embodiment, a first hinge is hinged on the cross bar 7, and a second hinge is hinged on the side of the plow column 1 away from the plow support 2. The first hinge has a threaded hole extending radially therethrough, and the second hinge has a through hole arranged radially.
