[0002] Before planting vegetables in a greenhouse, it is usually necessary to turn the soil over and maintain it. The crop residues, weeds and fertilizers on the surface need to be turned into the soil to improve the sowing quality of the soil in the greenhouse. The buried fertilizer can adjust the vertical distribution of soil nutrients and turn the compacted soil layer of a certain depth into a loose tillage layer, which can increase the soil porosity and facilitate the reception and storage of rainwater. Currently, the soil turning and maintenance process is usually carried out using a tiller.

[0003] The existing tiller includes an engine, a driving device, a rotating shaft and a tilling blade. The driving device drives the rotating shaft to rotate, and the rotating shaft drives the tilling blade to rotate. The tilling blade is inserted into the ground to turn up the soil and turn the compacted soil layer into a loose tillage layer.

[0004] However, the tilling blades of traditional tillers are usually fixed on the rotating shaft, and the width range that the tilling blades can cover during rotation cannot be adjusted, and they cannot be used for tilling ridges of various widths. In addition, since the traditional tilling blades are L-shaped, the area of ​​action on the soil blocks during the tilling process is small, and therefore there is often a problem of hard soil blocks remaining after tilling, making it difficult to carry out targeted tilling and crushing according to soils of different hardness.

A bearing 8 is connected between the rotating shaft 7 and the fixed seat 6. The rotating shaft 7 is connected to the fixed seat 6 through the bearing 8. The fixed seat 6 is rotatably connected, and first telescopic shafts 9 are arranged on both sides of the rotating shaft 7, and second telescopic shafts 10 are arranged on the sides away from each other of the two first telescopic shafts 9, and the first telescopic shaft 9 and the second telescopic shaft 10 are used to extend the length of the rotating shaft 7, and the outer walls of the two ends of the rotating shaft 7 and the ends of the two first telescopic shafts 9 away from each other are connected with fixed disks 12, and the middle part of the first telescopic shaft 9 and the outer walls of the ends of the two second telescopic shafts 10 away from each other are connected with movable disks 13, the outer wall of the fixed disk 12 is connected with a fixed blade 14, and the outer wall of the movable disk 13 is connected with a movable blade 15, and the fixed blade 14 and the movable blade 15 are used to be inserted into the ground to turn over the soil.

[0023] Specifically, telescopic grooves 20 are provided on both sides of the rotating shaft 7 and on the side where the two first telescopic shafts 9 are away from each other. The cross-section of the telescopic groove 20 is rectangular, so that the inner wall of the telescopic groove 20 can push the first telescopic shaft 9 and the second telescopic shaft 10 to rotate when the rotating shaft 7 rotates. Through holes 21 are provided on the upper and lower sides of the telescopic groove 20. Each telescopic groove 20 corresponds to two through holes 21, which are respectively used for positioning the first telescopic shaft 9 and the second telescopic shaft 10 in the retracted state and the extended state. A positioning bolt 22 is provided inside the through hole 21.

[0024] Furthermore, the first telescopic shaft 9 and the second telescopic shaft 10 are both in the shape of a rectangular rod. The first telescopic shaft 9 is inserted into the telescopic groove 20 to form a sliding connection with the rotating shaft 7. The second telescopic shaft 10 is inserted into the telescopic groove 20 to form a sliding connection with the first telescopic shaft 9. The second telescopic shaft 10 is pulled out from the first telescopic shaft 9, and the first telescopic shaft 9 is pulled out from the rotating shaft 7. The first telescopic shaft 9 and the second telescopic shaft 10 drive two movable disks 13 and a fixed disk 12 to move, and the separation of the movable disk 13 and the fixed disk 12 drives the fixed blade 14 and the movable blade 15 to separate, thereby increasing the width covered by the fixed blade 14 and the movable blade 15 when turning the soil.

[0025] Furthermore, a pull ring 11 is connected to the sides of the two second telescopic shafts 10 that are away from each other.

After the first telescopic shaft 9 and the second telescopic shaft 10 are pulled out, the positioning bolt 22 passes through the through hole 21 to position the first telescopic shaft 9 and the second telescopic shaft 10 to prevent the first telescopic shaft 9 and the second telescopic shaft 10 from sliding freely in the telescopic groove 20.

[0026] Furthermore, the fixed disk 12 and the movable disk 13 are both in annular shape, and there are four fixed disks 12 and movable disks 13, and two are symmetrically arranged relative to the rotating shaft 7 in a group. The two fixed disks 12 in the same group are respectively welded and fixed to the outer walls of the rotating shaft 7 and the first telescopic shaft 9, and the two movable disks 13 in the same group are respectively welded and fixed to the outer walls of the first telescopic shaft 9 and the second telescopic shaft 10. When the rotating shaft 7 rotates, the first telescopic shaft 9 and the second telescopic shaft 10 are driven to rotate, and the rotating shaft 7, the first telescopic shaft 9 and the second telescopic shaft 10 drive the fixed disk 12 and the movable disk 13 to rotate.

[0027] Furthermore, the fixed plate 12 and the movable plate 13 are provided with screw holes 16, and the screw holes 16 are provided with mounting screws 17. The movable plate 13 is provided with a slide groove 18, and the movable blade 15 is provided with a mounting hole 19. The movable blade 15 is slidably connected with the slide groove 18.

In the process of the fixed blade 14 turning the soil, the movable blade 15 crushes the turned-up soil blocks, so that the device can be realized. To switch between the soil turning state and the soil crushing state, the mounting screw 17 passes through the fixed blade 14 and is threadedly connected with the screw hole 16 in the fixed plate 12. There are two mounting holes 19, and the two mounting holes 19 correspond to the movable blade 15 to form an L shape and an F shape with the fixed blade 14 respectively. The mounting screw 17 passes through the mounting hole 19 and is threadedly connected with the screw hole 16 in the movable plate 13. The mounting screw 17 passes through the fixed blade 14 and the movable blade 15 and is connected with the screw hole 16, and the fixed blade 14 and the movable blade 15 are respectively installed in the fixed plate 12 and the movable plate 13.

[0028] The method of using the present embodiment is as follows: when the user is actually turning the soil in the greenhouse for maintenance, first the frame 1 is placed on the ground to be turned over, the engine 2 is turned on, the engine 2 drives the driving motor to rotate, the driving motor drives the rotating shaft 7 to rotate through the transmission group, the rotating shaft 7 drives the first telescopic shaft 9 and the second telescopic shaft 10 to rotate, the rotating shaft 7, the first telescopic shaft 9 and the second telescopic shaft 10 drive the fixed plate 12 and the movable plate 13 to rotate, the fixed plate 12 and the movable plate 13 respectively drive the fixed blade 14 and the movable blade 15 to rotate, at this time the fixed blade 14 and the movable blade 15 are combined to form an L shape for turning the soil, and at the same time the frame 1 is pushed by the operating handle 4 so that the frame 1 moves on the ground through the bottom roller 5, and the soil in the greenhouse is turned over and maintained in turn. When the soil is too dry and the soil block hardness is high, the movable blade 15 is pushed to slide in the slide groove 18 so that the movable blade 15 moves relative to the fixed blade 14, and the two are still in a combined state and form an F shape, and then the mounting screw 1 is installed. 7 penetrates the mounting hole 19 and is connected with the screw hole 16 to fasten the movable blade 15. When the fixed blade 14 turns the soil, the movable blade 15 crushes the turned-up soil blocks to increase the fineness of the turned soil and avoid residual hard soil blocks. When it is used for turning the soil on a wider ridge or reducing the reciprocating frequency of turning the soil, the positioning bolt 22 can be loosened, and the pull ring 11 is pulled, and the pull ring 11 pulls the second telescopic shaft 10 to slide in the telescopic groove 20, so that the second telescopic shaft 10 is pulled out from the first telescopic shaft 9. By utilizing the limiting effect between the second telescopic shaft 10 and the first telescopic shaft 9, the first telescopic shaft 9 is pulled to slide in the telescopic groove 20, so that the first telescopic shaft 9 is pulled out from the rotating shaft 7. At the same time, the first telescopic shaft 9 and the second telescopic shaft 10 drive two movable disks 13 and a fixed disk 12 to move, and the separation of the movable disk 13 and the fixed disk 12 drives the separation of the fixed blade 14 and the movable blade 15, so that the fixed blade 14 and the movable blade 15 cover a larger width when turning the soil, and the device has a wider range of turning the soil at a single time.
