[0026] EMBODIMENT

[0027] As Figures 1-6 shown, an agricultural planting soil turning equipment in the field of agricultural machinery, including the bearing rod 1 of the week side fixed sleeve has at least a pair of limit ring and the vertical guide frame 3 fixed on the pair of limit ring;

[0028] Still include rotating sleeve in the outside of bearing rod 1 and located between the pair of limit ring rotating ring 5, fixed in the bottom of rotating ring 5 and the lowest point is located in the vertical direction of the center of bearing rod 1 turning tooth 6 and fixed in the top of rotating ring 5 protrusion 7;

[0029] Still include the inclined plate 9 of vertical sliding on vertical guide frame 3, the reset spring 8 of fixed between vertical guide frame 3 and inclined plate 9 and the upward extrusion of inclined plate 9 and the block 11 of sliding in horizontal direction and the downward extrusion of inclined plate 9;

[0030] The included angle between the inclined surface on the inclined plate 9 and the horizontal plane is between 60 degrees-80 degrees, and the inclined surface on the block 11 is attached to the inclined surface on the inclined plate 9;

[0031] When encountering obstacles, the turning tooth 6 rotates clockwise, the protrusion 7 extrudes the block 11 to move horizontally in the direction of turning, extrudes the inclined plate 9, and the height of the lowest point of the turning tooth 6 rises to avoid obstacles;

[0032] In the process of turning, when encountering obstacles, the turning tooth 6 will rotate clockwise due to the obstruction of the obstacles, the height of the lowest point of the turning tooth 6 rises, at this time the protrusion 7 will extrude the block 11 to move in the direction of turning, the block 11 extrudes the inclined plate 9, and the inclined plate 9 drops until the lowest point of the turning tooth 6 passes the obstacle, and finally the reset spring 8 extrudes the inclined plate 9 to reset;

[0033] By setting the included angle between the inclined surface of the inclined plate 9 and the horizontal plane to be between 60 degrees and 80 degrees, the inclined plate 9 can have a smaller horizontal component force when being pressed strongly, so that the inclined plate 9 is difficult to descend, that is, the inclined plate 9 is difficult to be pressed to descend in the normal state, unless an obstacle is encountered, the force between the obstacle and the turning tooth 6 is large, in order to avoid damage to the turning tooth 6, the lowest point of the turning tooth 6 can be lifted by the descent of the inclined plate 9, so as to avoid the obstacle.

[0034] The inclined surface of the inclined plate 9 and the inclined surface of the abutting block 11 are rough, and the inclined surface of the inclined plate 9 covers the inclined surface of the abutting block 11.

[0035] By roughening the inclined surface of the inclined plate 9 and the inclined surface of the abutting block 11, the abutting block 11 can be more difficult to press the inclined plate 9, and by covering the inclined surface of the abutting block 11 with the inclined surface of the inclined plate 9, the contact area can be increased, so that the abutting block 11 is more difficult to press the inclined plate 9, and when an obstacle is encountered, the turning tooth 6 is not easy to rotate, and a larger force is required to rotate the turning tooth 6.

[0036] The bearing rod 1 is fixed with a shielding frame 2 for limiting the counterclockwise rotation of the protrusion 7, and the shielding frame 2 is located on the side of the protrusion 7 away from the abutting block 11.

[0037] By arranging the shielding frame 2, the protrusion 7 can be blocked, so that the turning tooth 6 is prevented from rotating counterclockwise.

[0038] The vertical guide frame 3 is fixed with a horizontal guide bent rod 4, and the abutting block 11 is fixed with a sliding block 10 penetrating through the horizontal guide bent rod 4 through a mounting rod.

[0039] By using the horizontal guide bent rod 4 and the sliding block 10 in combination, the abutting block 11 can only slide in the horizontal direction.

[0040] The vertical guide frame 3 is provided with a vertical T-shaped sliding groove, and the side of the inclined plate 9 close to the vertical guide frame 3 is fixed with a T-shaped sliding block in sliding fit with the T-shaped sliding groove.

[0041] By using the T-shaped sliding groove and the T-shaped sliding block in combination, the inclined plate 9 can stably slide in the vertical direction.

[0042] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications shall all belong to the protection scope of the utility model.
