[0029] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0030] Example 1

[0031] This embodiment provides a green manure turning device with adjustable turning range, including: a main frame 1, a spacing adjustment mechanism 2, a depth adjustment mechanism 3, an inclination adjustment mechanism 4, and a plow blade 5;

[0032] The spacing adjustment mechanism 2 includes a first driving device 6, a lead screw 7, a scissor-type connecting rod 8, five mounting blocks 9, and a guide rail 10. Two plates are mounted on the side of the main frame 1, and the guide rail 10 is mounted on one side of the main frame 1 via the plates. The mounting blocks 9 are slidably connected to the guide rail 10. The scissor-type connecting rod 8 includes three X-shaped movable rods with their ends hinged to each other sequentially. Each X-shaped movable rod is formed by two rods 11 hinged together, and also includes four short rods. The four short rods are grouped in pairs, with the ends of the two short rods in each group hinged together, and the remaining two ends hinged to the two ends of the outer X-shaped movable rod. Each mounting block 9 corresponds to one X-shaped movable rod and is hinged to the hinge points of the two rods 11 in the X-shaped movable rod. The mounting blocks on both sides are hinged to the hinge points of the ends of the two short rods. When the scissor-type connecting rod 8 extends or retracts, it can drive the mounting blocks 9 to slide on the guide rail 10, thereby changing the spacing between each mounting block 9.

[0033] In this embodiment, the first driving device 6 is a servo motor. The first driving device 6 is installed on one side of the main frame 1. The lead screw 7 is driven and connected to the output end of the first driving device 6. The outermost mounting block 9 near the free end of the lead screw 7 is threadedly connected to the lead screw 7. The middle mounting block 9 is fixedly connected to the main frame 1. The spacing adjustment mechanism 2 also includes a limiting plate 24, which is installed on the side of the main frame 1. The limiting plate 24 includes a first limiting plate 24 and a second limiting plate 24. The first limiting plate 24 has a through hole. The lead screw 7 passes through the through hole of the first limiting plate 24 and abuts against the side of the second limiting plate 24.

[0034] The depth adjustment mechanism 3 is installed on the mounting block 9, the tilt adjustment mechanism 4 is installed on the working end of the depth adjustment mechanism 3, and the plow blade 5 is installed on the working end of the tilt adjustment mechanism 4. The tilt adjustment mechanism 4 is used to adjust the angle at which the plow blade 5 plows the ground.

[0035] The depth adjustment mechanism 3 includes a second drive device 12 and a support rod 13. The support rod 13 is connected to the output end of the second drive device 12. The second drive device 12 is used to control the support rod 13 to move up and down in the vertical direction, thereby controlling the vertical height of the plow blade 5. In this embodiment, a cylinder is used as the second drive device 12.

[0036] The depth adjustment mechanism 3 also includes a limiting device 14, which includes two vertical rods and a fixing plate. The vertical rods are fixed on the second driving device 12 and are parallel to the support rod 13. The fixing plate is fixedly connected to the two vertical rods perpendicular to the vertical rods. A through hole is provided in the middle of the fixing plate, through which the support rod 13 passes. When the second driving device 12 drives the support rod 13 to move up and down, the opening in the middle of the fixing plate can limit the swaying of the support rod 13.

[0037] Before starting the tobacco green manure turning operation, the operator adjusts the vertical height of multiple plow blades 5 according to the soil conditions through the depth adjustment mechanism 3, then changes the tilt angle of the plow blades 5 through the tilt angle adjustment mechanism 4 so that the plow blades 5 can fit in contact with the soil surface, and then adjusts the spacing between multiple plow blades 5 through the spacing adjustment mechanism 2, thereby adjusting the turning range.

[0038] Taking a concentrated compaction operation as an example, when the spacing between multiple plow blades 5 is adjusted by the spacing adjustment mechanism 2, the first drive device 6 drives the lead screw 7 to rotate. At this time, the mounting block 9 threadedly connected to the lead screw 7 will move towards the mounting block 9 closer to the middle, causing the scissor linkage 8 to retract. The retraction of the scissor linkage 8 will cause the mounting block 9 hinged to the X-shaped movable rod to also move towards the mounting block 9 closer to the middle, thereby reducing the spacing between the mounting blocks 9, which is the spacing between the plow blades 5.

[0039] When a more concentrated turning and compaction operation is required, the distance between adjacent plow blades 5 can be reduced again. Through the cooperation of the first drive device 6, lead screw 7, scissor linkage 8, five mounting blocks 9 and guide rail 10, the device can flexibly adjust the distance between multiple plow blades 5 according to the green manure turning and compaction situation. It can not only carry out large-scale uniform turning and compaction operations, but also small-scale concentrated turning and compaction operations, which improves the practicality of the device and the quality of tobacco green manure turning and compaction.

[0040] Example 2

[0041] This embodiment provides a green manure turning device with an adjustable turning range. Based on embodiment 1, this embodiment differs from embodiment 1 in that the tilt angle adjustment mechanism 4 includes a horizontal support plate 15, a first vertical support plate 16, a second vertical support plate 17, a fixed toothed disc 18, a rotating toothed disc 19, a rotating shaft 20, a spring 21, a push rod 22, and a support shaft 23.

[0042] The horizontal support plate 15 is connected to the lower end of the depth adjustment mechanism 3 in the height direction. The first vertical support plate 16 and the second vertical support plate 17 are respectively perpendicular to the horizontal support plate 15 and connected to the two ends of the horizontal support plate 15. The first vertical support plate 16 has a groove on the side near the second vertical support plate 17. The second vertical support plate 17 has a through hole at the corresponding position. One end of the spring 21 is fixedly connected to the inside of the groove, and the other end is fixedly connected to one end of the support shaft 23. The other end of the support shaft 23 is rotatably connected to one end of the rotating shaft 20. The other end of the rotating shaft 20 is fixedly connected to the rotating gear 19. The fixed gear 18 is fixedly connected to the side of the second vertical support plate 17 near the first vertical support plate 16, and the center of the fixed gear 18 is set at the position where the through hole is opened. The center of the fixed gear 18 also has a through hole. The push rod 22 passes through the through holes on the second vertical support plate 17 and the fixed gear 18, and is fixedly connected to the center of the side of the rotating gear 19 near the second vertical support plate 17. The fixed gear 18 and the rotating gear 19 mesh with each other.

[0043] The plow blade 5 is fixedly connected to the side of the rotating shaft 20.

[0044] When the tilt angle of the plow blade 5 needs to be adjusted, push the push rod 22 to drive the rotating toothed disc 19, rotating shaft 20 and support shaft 23 to move toward the first vertical support plate 16, compressing the spring 21. At this time, the rotating toothed disc 19 disengages from the fixed toothed disc 18. Rotate the push rod 22 to drive the rotating toothed disc 19 and rotating shaft 20 to rotate until the plow blade 5 reaches the required tilt angle and is in contact with the soil surface. Then release the push rod 22, the spring 21 returns to its original position, and drives the rotating toothed disc 19 to engage with the fixed toothed disc 18 again to maintain the stability of the tilt angle of the plow blade 5. Then the tobacco green manure turning and compaction operation can be carried out.

[0045] In this embodiment, the plow blade 5 can perform green manure turning operations on soil at different heights and tilt angles by the cooperation of the turning depth adjustment mechanism 3 and the tilt angle adjustment mechanism 4, further improving the practicality of the device.
