[0036] The lower end of the connecting seat 9 is fixedly connected with a furrowing member 10, which is a commonly used furrowing device structure, used for furrowing and fertilizing in loose plough layers, and has a cutting edge, so the furrowing resistance is small; the connecting seat 9 is a Y-shaped structure, and the upper end of the connecting seat 9 has hinge points, which are set as points B and C. The upper end of the connecting seat 9 is hinged to the main support and the linkage structure respectively with points B and C as hinge points;

[0037] The reset structure transmits torque through the linkage structure, so that the connecting seat 9 moves with point B as the center of the circle; the linkage structure is used to connect the reset structure and the connecting seat 9 and transmit torque to achieve linkage and reset of the reset structure and the groove opening member 10.

[0038] Furthermore, the main body bracket includes two first connecting plates 1, which are symmetrically arranged, and a sleeve is arranged between the two first connecting plates 1. Bolts are passed through the sleeve and the two first connecting plates 1 on both sides of the sleeve and locked to form an integral main body bracket.

[0039] Furthermore, the specific structure of the linkage structure includes a special-shaped connecting member 5, two oppositely arranged third connecting plates 6, a fourth connecting plate 7 and a fifth connecting plate 8;

[0040] The lower ends of the two third connecting plates 6 are respectively hinged to the second connecting plate 4, and the upper ends of the two third connecting plates 6 are hinged together with the point E on the upper part of the special-shaped connecting member 5 as the hinge point;

[0041] The special-shaped connecting piece 5 is arranged between the two first connecting plates 1. The special-shaped connecting piece 5 is a plate-like structure with three hinge points, namely point D, point E and point F; the front end of the special-shaped connecting piece 5 is hinged to the first connecting plate 1 with point F as the hinge point; the rear end of the special-shaped connecting piece 5 is provided with a sleeve with a thread, and an adjusting bolt is screwed into the bottom of the sleeve; the reset position of the connecting seat 9 and the groove opening piece 10 can be adjusted by adjusting the adjusting bolt; the adjusting bolt can be used in conjunction with a locking nut, and when the position of the adjusting bolt is adjusted, the locking nut is used to lock the adjusting bolt and the sleeve.

[0042] There are two fourth connecting plates 7, which are symmetrically connected to point D of the special-shaped connecting member 5. The front ends of the two fourth connecting plates 7 are hinged to the special-shaped connecting member 5 with point D as the hinge point; the rear ends of the two fourth connecting plates 7 are hinged to the connecting seat 9 at point C.

[0043] The fifth connecting plate 8 is fixed between the two fourth connecting plates 7 and contacts the bottom of the adjusting bolt.

[0044] When the second connecting plate 4 rotates around point A under the action of the tension spring 3, the special-shaped connecting piece 5 and the third connecting plate 6 move synchronously at point E; under the action of the tension spring 3, the bottom end of the adjusting bolt is pressed on the top surface of the fifth connecting plate 8; when adjusting the adjusting bolt, the relative position of the fourth connecting plate 7 and the special-shaped connecting piece 5 can be changed, so that the fourth connecting plate 7 rotates with point D as the center of the circle. The rotation of the fourth connecting plate 7 will drive the connecting seat 9 to rotate with point B as the center of the circle, and the connecting seat 9 will drive the groove opening piece 10 to move, thereby achieving the effect of adjusting the position of the groove opening piece 10 in the reset state.

[0045] Furthermore, the reset structure also includes a tension spring seat 2; the tension spring seat 2 is fixed on the first connecting plate 1, and one end of the tension spring 3 is hung on the tension spring seat 2; the corresponding first connecting plate 1 is provided with a plurality of mounting holes located at different positions, and the tension spring seat 2 can be installed on the mounting holes at different positions by bolts according to the situation. The tension spring seat 2 is used to fix one end of the tension spring 3. By changing the installation position of the tension spring seat 2, the stretching length of the tension spring 3 can be adjusted and then the output tension force can be adjusted, so that the ditching component can adapt to different working conditions.

[0046] Furthermore, the connecting seat 9 is provided with a plurality of mounting holes along its length direction, and the ditching member 10 is mounted on the selected mounting holes by bolts, and the mounting height of the ditching member 10 can be adjusted by selecting different mounting holes.

[0047] Furthermore, a fertilizer guiding structure is provided on the trenching member 10. The fertilizer guiding structure is a slide groove structure provided along the rear edge of the trenching member 10. The fertilizer guiding structure on the trenching member 10 enables fertilization to be carried out while trenching, thereby achieving two goals at one stroke and improving the efficiency of agricultural operations.

[0048] The working principle and process are as follows:

[0049] Before starting the operation, the operator needs to adjust the initial position and reset position of the trenching member 10 by adjusting the bolts according to the hardness of the soil and the operation requirements. The trenching member is connected to the traction device and all the hinge points are ensured to be correctly connected.

[0050] The traction equipment is started, and the trenching member 10 is extended into the ground to start trenching. As the trenching member 10 is extended into the ground, it is subject to resistance from the soil, which causes the connecting seat 9 to move backward, thereby driving the fourth connecting plate 7 and the fifth connecting plate 8 hinged thereto to rotate upward as a whole.

[0051] The upward rotation of the fourth connecting plate 7 and the fifth connecting plate 8 pushes the adjusting bolts, and the adjusting bolts then drive the special-shaped connecting member 5 to rotate upward.

[0052] The rotation of the special-shaped connecting member 5 further drives the third connecting plate 6, and the third connecting plate 6 drives the second connecting plate 4 to rotate with point B as the center.

[0053] The rotation of the second connecting plate 4 stretches the tension spring 3, and the tension spring 3 provides a greater tension to adapt to the working state after being stretched.

[0054] In the working state, the trenching member 10 automatically adjusts the trenching pressure according to the soil hardness under the action of the tension spring 3 to maintain the trenching depth and quality to adapt to different soil conditions.

[0055] Reset after work:

[0056] At this time, the trenching member 10 leaves the ground and is no longer stressed. The tension spring 3 is in the shortest length state, and the tension spring 3 drives the second connecting plate 4 to rotate with point A as the center. The second connecting plate 4 drives the third connecting plate 6 to move downward, and then the third connecting plate 6 drives the special-shaped connecting member 5 to move downward with point F as the center. The adjusting bolt on the special-shaped connecting member 5 presses the fourth connecting plate 7 and the fifth connecting plate 8 downward as a whole, and the fourth connecting plate 7 drives the connecting seat 9 to rotate with point B as the center. When the upper surface of the connecting seat 9 rotates to contact with the fifth connecting plate 8, the connecting seat 9 is blocked by the fifth connecting plate 8 and reaches the reset position, completing the reset work.

[0057] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
