[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is in conjunction with the appendix Figures 1-3 The trench excavation component of this utility model is described in detail below.

[0028] The trenching assembly of this utility model embodiment includes a body 1 and a connector 2. The body 1 includes a surrounding plate 11 and a bottom plate 12. The surrounding plate 11 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114. The first plate 111, second plate 112, third plate 113, and fourth plate 114 are connected end-to-end to form a chamber 13. The first plate 111 and third plate 113 are spaced apart in a first direction, and the second plate 112 and fourth plate 114 are spaced apart in a second direction and symmetrically arranged along the centerline of the first plate 111 in the second direction. The second direction is orthogonal to the first direction. The dimension of the first plate 111 in the second direction is larger than the dimension of the third plate 113 in the second direction. The bottom plate 12 is connected to the first plate 111, second plate 112, third plate 113, and fourth plate 114 to close one end of the chamber 13. The connector 2 is located on the outside of the first plate 111 and is adapted to be rotatably connected to a driving member to drive the body 1 to rotate around the second direction under the drive of the driving member.

[0029] The trenching assembly of this utility model embodiment forms a chamber 13 by connecting a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114 end to end. The first plate 111 and the third plate 113 are spaced apart in a first direction, and the second plate 112 and the fourth plate 114 are spaced apart in a second direction. The dimension of the first plate 111 in the second direction is larger than the dimension of the third plate 113 in the second direction, so that on a projection plane parallel to both the first and second directions, the outer periphery of the body 1 is... It is generally trapezoidal in shape, with the second plate 112 and the fourth plate 114 being trapezoidal side plates. The bottom plate 12 is connected to the surrounding plate 11 to enclose one end of the chamber 13. It is rotatably connected to the driving member by the connecting member 2, so that the body 1 can rotate around the second direction under the driving action of the driving member to excavate the land. By using the inclined plates of the second plate 112 and the fourth plate 114, the trench wall surface of the excavated trench is inclined, which avoids the trench wall from collapsing, improves the stability of the trench, and ensures the normal use of the trench.

[0030] Specifically, such as Figures 1-3 As shown, the first direction is consistent with the front-back direction, and the second direction is consistent with the left-right direction. The first plate 111 and the third plate 113 are arranged alternately in the front-back direction, and the second plate 112 and the fourth plate 114 are arranged alternately in the left-right direction. The dimension of the first plate 111 in the left-right direction is larger than that of the third plate 113 in the left-right direction, and the second plate 112 and the fourth plate 114 are arranged symmetrically in the left-right direction. The bottom plate 12 is connected to the lower ends of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 to close the lower end of the chamber 13, leaving the upper end of the chamber 13 open.

[0031] Connector 2 is located on the outside of the first plate 111. Connector 2 enables a rotatable connection between the main body 1 and the driving component, so that the driving component can drive the main body 1 to rotate around the second direction. During the rotation of the main body 1, the third plate 113 first contacts the ground and excavates downward. The narrower design of the third plate 113 compared to the first plate 111 guides the main body 1 to continue moving downward, reducing frictional resistance. At the same time, the inclined plates 112 and 114 further guide the main body 1 to slide along the trench wall, preventing trench wall collapse and improving the stability of the trench wall while ensuring the ease of movement of the main body 1.

[0032] Compared to related technologies where the outer contour of the body 1 is rectangular and the excavated trench is also rectangular, and the slope of the trench wall needs to be set after the trench is excavated, this embodiment sets the outer contour of the body 1 to be trapezoidal, so that the excavated trench is a trapezoidal trench, that is, the trench wall of the excavated trench is inclined, which improves the excavation efficiency and the stability of the trench.

[0033] The trench excavation component of this embodiment can be applied in scenarios with high groundwater levels, high soil moisture content, and where the walls of manually excavated trenches are prone to collapse, thereby improving the efficiency and quality of trench excavation and thus improving the efficiency and quality of land reclamation.

[0034] Optionally, the second plate 112 and the fourth plate 114 are made of 8-10mm thick Q345 steel plates to improve their resistance to soil lateral pressure and prevent landslides.

[0035] Optionally, the base plate 12 is a steel plate with a thickness of 12mm. The base plate 12 bears the weight of the surrounding plate 11, and the flatness of the base plate 12 ensures the flatness of the bottom of the trench.

[0036] Optionally, the first plate 111 has a left-right dimension of 800-1000 mm, and the third plate 113 has a left-right dimension of 500 mm, adapting to the standard cross-sectional dimensions of agricultural ditches. Of course, other dimensions can also be determined according to actual conditions.

[0037] In some embodiments, such as Figure 1 As shown, the third plate 113 is an arc-shaped plate, which protrudes in the direction away from the chamber 13. By setting the third plate 113 as an arc-shaped plate, the body 1 is guided to slide on the groove wall, which further reduces the frictional resistance between the body 1 and the groove wall while improving the flatness and stability of the groove wall.

[0038] In some embodiments, the curvature of the arc plate is 90° to 120°. By setting the curvature of the arc plate to 90° to 120°, the curvature of the arc plate is avoided from being too large or too small, which would affect the flatness of the trench wall.

[0039] Optionally, the curvature of the curved plate is 90°, 100°, 110°, 115°, or 120°.

[0040] In some embodiments, the third plate 113 has a chamfer at at least one end in the second direction. By providing a chamfer at at least one end of the third plate 113 in the second direction, the structural strength of the third plate 113 is ensured while the smoothness of the trench wall is improved.

[0041] Specifically, the third plate 113 has a chamfer at at least one end in the second direction, which can be understood as: the left end of the third plate 113 has a chamfer; or, the right end of the third plate 113 has a chamfer; or, both the left and right ends of the third plate 113 have chamfers.

[0042] In some embodiments, the trench excavation assembly further includes a partition plate 3 disposed within the chamber 13. The partition plate 3 is connected to a first plate 111 and a third plate 113 to divide the chamber 13 into a first chamber 131 and a second chamber 132 arranged at intervals in a second direction.

[0043] Specifically, such as Figures 1-3 As shown, the partition plate 3 extends in the front-to-back direction and is connected to the first plate 111 and the third plate 113. The lower end of the partition plate 3 is connected to the bottom plate 12. By setting the partition plate 3, the soil pressure is dispersed, the body 1 is prevented from deforming, and the structural strength and compressive strength of the body 1 are improved.

[0044] It is understandable that in areas with high groundwater levels, the soil moisture content is high, and the body 1 in the related technology is prone to deformation during long-term excavation. In this embodiment, by setting a partition plate 3 in the chamber 13 and connecting the partition plate 3 with the first plate 111, the third plate 113 and the bottom plate 12, the partition plate 3 is connected to the body 1 as a whole, thereby improving the compressive strength of the body 1 and ensuring the regularity of the excavated trench.

[0045] For example, partition 3 is made of steel plate with a thickness of 6mm.

[0046] In some embodiments, such as Figures 1-3 As shown, the partition plate 3 has a notch 31 on the side adjacent to the third plate 113 and away from the bottom plate 12. By setting the notch 31 at the upper end of the partition plate 3, the first chamber 131 and the second chamber 132 are connected through the notch 31, which facilitates the movement of soil in the first chamber 131 toward the second chamber 132, and also facilitates the movement of soil in the second chamber 132 toward the first chamber 131, thus dispersing soil pressure and preventing deformation of the main body 1.

[0047] In some embodiments, such as Figure 2 and Figure 3As shown, a first reinforcing rib 41 is provided between the partition plate 3 and the first plate 111. By providing the first reinforcing rib 41 between the partition plate 3 and the first plate 111, the connection strength between the first plate 111 and the partition plate 3 is improved.

[0048] Optionally, there are two first reinforcing ribs 41, which are symmetrically arranged in the left and right directions to further improve the connection strength between the first plate 111 and the partition plate 3.

[0049] Optionally, the first stiffener 41 is a triangular rib with a bending stress greater than or equal to 200 MPa.

[0050] In some embodiments, such as Figure 3 As shown, a second reinforcing rib 42 is provided between the connector 2 and the first plate 111. By providing the second reinforcing rib 42 between the connector 2 and the first plate 111, the connection strength between the connector 2 and the first plate 111 is improved.

[0051] Optionally, there are two second reinforcing ribs 42, which are symmetrically arranged in the left and right directions to further improve the connection strength between the connector 2 and the first plate 111.

[0052] Optionally, the second stiffener 42 is a triangular rib with a bending stress greater than or equal to 200 MPa.

[0053] In some embodiments, such as Figure 1 As shown, there are two connectors 2, which are spaced apart in the second direction, and both connectors 2 are rotatably connected to the driving component. By using two connectors 2, the connection stability between the connectors 2 and the driving component is improved.

[0054] In some embodiments, such as Figure 1 As shown, the connector 2 has a connecting groove 21 that extends through the connector 2 along its thickness direction. The connecting groove 21 is rotatably connected to the drive component via a rotating shaft. The connector 2 allows the drive component to drive the body 1 to achieve multi-angle traction, thus improving excavation efficiency.

[0055] Specifically, the connector 2 has a connecting groove 21 that runs through the connector 2 in the left-right direction, and the rotating shaft extends in the left-right direction and passes through the connecting groove 21 of the two connectors 2, so as to realize the rotational connection between the connector 2 and the driving member, and facilitate the body 1 to rotate around the rotating shaft.
