[0002] If mulch and plastic bags are not completely cleaned up, they cannot be completely decomposed in the soil, forming harmful lumps. Plastic bag garbage is not easy to degrade when applied to the soil, causing compaction. Compaction reduces the soil's ability to absorb water, oxygen and nutrients, and the decrease in permeability causes poor development of crop roots, affecting the growth and development of crops.

[0003] The treatment of soil compaction usually adopts the method of combined land preparation with large agricultural machinery. Large agricultural machinery is usually used on sunny days when the soil is relatively dry, and the soil is easily broken into small pieces by the cutting of large agricultural machinery. However, in rainy areas, the soil often remains moist, and large agricultural machinery has a poor effect on the treatment of moist and compacted soil. Summary of the invention

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] like Figure 1-5 As shown, a device for ecological land restoration and management includes a fixing member 1, a driving member 2, a guide mechanism, a turntable 3, and two or more cutting mechanisms arranged equidistantly along the axial direction of the turntable 3, the fixing member 1 is used to limit the position of the driving member 2, the driving member 2 is used to drive the turntable 3 to rotate, and the guide mechanism is used to drive the turntable 3 to move up and down;

[0030] The cutting mechanism comprises a connecting rod 4 arranged on a rotating disk 3, and two or more cutting blades 5 for cutting soil are fixed on the connecting rod 4 at equal distances along its axial direction.

[0031] In the above embodiment, the fixing member 1 is fixed on the traction device, so that the present invention is fixed, and the traction device can be used to drive the present invention to move in the field. The driving member 2 drives the turntable 3 to rotate, so that the cutting mechanism on the turntable 3 makes a circular motion along the axis of the turntable 3. When the present invention moves, the cutting blade block 5 extends into the soil, and the cutting blade block 5 breaks and cuts the soil when rotating. In the process of the cutting blade block 5 moving forward with the traction device, it can not only turn up the soil, so that the deep plow bottom layer is brought up, but also increase the number of soil crushing times during the rotation process. The position of the cutting blade block 5 changes continuously during the rotation process, so that the soil can be fully cut and crushed, and the plow bottom layer brought up is broken. The present invention performs rotary cutting of the soil by the continuously moving and rotating cutting blade block 5, so that the soil is repeatedly cut, thereby improving the compaction of wet soil, which is helpful for farmers to carry out agricultural activities.

[0032] As a further solution of the present invention, the guiding mechanism includes a circular ring 6 arranged on the fixing member 1, the bottom end of the circular ring 6 is a wavy structure, a top rod 7 is provided on the top of the turntable 3, the top rod 7 is used to contact the circular ring 6 and drive the turntable 3 to move up and down, the driving member 2 is movably connected to the fixing member 1, a reset spring is provided between the driving member 2 and the fixing member 1, and the driving member 2 is an electric motor.

[0033] In the above embodiment, the top rod 7 is driven to rotate during the rotation of the turntable 3, so that the top of the top rod 7 moves along the bottom contour of the ring 6. Because the bottom of the ring 6 is a wavy structure, the top rod 7 causes the turntable 3 to produce intermittent up and down reciprocating motion during the movement. When the cutting mechanism moves downward, it drives the driving member 2 to move downward, so that the reset spring is stretched. When the top rod 7 moves to the position of the wave crest at the bottom of the ring 6, the driving member 2 and the cutting mechanism are pulled upward under the action of the reset spring. The process of the cutting blade block 5 being lifted upward further increases its turning-up effect on the plow bottom layer, so that the plow bottom layer is brought into the soil surface, thereby facilitating the mixing and crushing of the soil.

[0034] As a further solution of the present invention, the cutting blade block 5 includes a No. 1 blade block 8, a No. 2 blade block 9 and a shovel block 10. The No. 1 blade block 8 and the No. 2 blade block 9 each include a No. 1 blade and a No. 2 blade that are rotatably connected. A return spring 11 is provided between the No. 1 blade and the No. 2 blade.

[0035] In the above embodiment, the first blade block 8 and the second blade block 9 of the cutting blade block 5 are arranged in two sections so that the cutting blade block 5 can be deformed when encountering stones and obstacles that cannot be cut and driven, that is, the second blade block 9 can rotate to a certain extent, so that the cutting blade block 5 can avoid obstacles, avoid the cutting blade block 5 from breaking during operation, and avoid the present invention as a whole from being shaken or even damaged, thereby ensuring the continuous operation of the present invention. At the same time, the cutting blade block 5 can collect plastic bags and rope-like objects in the soil during movement and hang them on the cutting blade block 5, which has the effect of removing impurities. The shovel block 10 is arranged at an angle, which can have a good soil turning effect. The soil can be lifted up during the upward movement of the shovel block 10, and it helps to drive the cutting blade block 5 into the soil during the downward movement.

[0036] As a further solution of the present invention, the cutting mechanism also includes a servo motor 12 fixed on the turntable 3, the output shaft of the servo motor 12 is fixedly connected to the connecting rod 4, a pressure sensor 13 is provided between the return spring 11 and the No. 2 blade, and the pressure sensor 13 is used to measure the relative position between the No. 1 blade and the No. 2 blade. A storage box 14 is provided at the top of the turntable 3, and the storage box 14 is used to store stones in the soil.

[0037] In the above embodiment, by providing a pressure sensor 13, when the cutting blade block 5 encounters a stone, a resistance is formed on the cutting blade block 5, so that the movement of the cutting blade block 5 is blocked, thereby causing the No. 2 blade to rotate to a certain extent. When the No. 2 blade rotates, it squeezes the return spring 11, so that the return spring 11 squeezes the pressure sensor 13. The measured value of the pressure sensor 13 is analyzed by the controller. When it is determined that the cutting blade block 5 carries a stone when moving, the servo motor 12 is started, and the servo motor 12 drives the connecting rod 4 to rotate, so that the cutting blade block 5 rotates. The cutting blade block 5 brings up the stone when rotating, and throws the stone into the storage box 14 when it reaches the storage box 14, and then the cutting blade block 5 rotates to the initial position. By collecting the stones, the normal operation of the cutting blade block 5 can be guaranteed, and the cleanliness of the soil can also be improved.

[0038] As a further solution of the present invention, the storage box 14 is provided with more than two connecting parts along its length direction, and the number of the connecting parts corresponds to the number of cutting blade blocks 5 in the cutting mechanism. A mounting groove is provided on the connecting plate, and a spool 15 is provided at the mounting groove. A telescopic rod 16 is provided at the bottom of the connecting part, and a collision block 17 is provided at the bottom end of the telescopic rod 16. A connecting rope 18 is provided between the collision block 17 and the corresponding cutting blade block 5 and passes through the spool 15.

[0039] In the above embodiment, when the cutting blade block 5 encounters an obstacle that cannot be driven, the pressure on the pressure sensor 13 increases suddenly. Under the control of the controller, the servo motor 12 drives the cutting blade block 5 to reverse, so that the cutting blade block 5 rotates in the direction away from the obstacle. When the cutting blade block 5 rotates to a horizontal state, the connecting rope 18 is in a relaxed state, so that the impact block 17 is in a free state. The impact block 17 moves downward under the action of its own gravity, and contacts the obstacle during the movement. When it contacts the obstacle, it forms a violent impact on the obstacle, so that the obstacle is broken or driven into the deep soil layer. The impact of the impact block 17 can reduce the obstruction of the subsequent cutting operation of the cutting blade block 5, which is conducive to the continuous operation of the present invention. When the horizontal cutting blade block 5 returns to the initial position driven by the servo motor 12, the connecting rope 18 is pulled, so that the impact block 17 is lifted up again, thereby ensuring that the impact block 17 can be reused.

[0040] As a further solution of the present invention, the telescopic rod 16 is a closed structure, and the air pressure inside the telescopic rod 16 is the same as the atmospheric pressure when the telescopic rod 16 is fully extended.

[0041] In the above embodiment, the volume of the telescopic rod 16 is reduced and the volume of the inner cavity is also small during the lifting of the impact block 17, thereby increasing the gas pressure inside the telescopic rod 16. The gas pressure inside the telescopic rod 16 makes the telescopic rod 16 have a tendency to extend, and provides thrust to the impact block 17 when the impact block 17 is in a free state, thereby making the impact block 17 have a large acceleration. The impact block 17 is accelerated to hit the obstacle under the push of the telescopic rod 16, thereby improving the clearing effect of the impact block 17 on the obstacle.

[0042] A method for land restoration and management using any of the above-mentioned devices for ecological land restoration and management comprises the following steps:

[0043] S1: Fix the fixing member 1 on the traction device, adjust the height of the turntable 3 so that the cutting mechanism enters the soil; fix the fixing member 1 on the traction device, thereby fixing the present invention, and the traction device can be used to drive the present invention to move in the field.

[0044] S2: The traction device drives the turntable 3 to move, and the driving member 2 drives the turntable 3 to rotate, so that the cutting mechanism rotates and performs rotational cutting on the compacted soil; the driving member 2 drives the turntable 3 to rotate, so that the cutting mechanism on the turntable 3 performs circular motion along the axis of the turntable 3. The cutting blade block 5 of the present invention extends into the soil during movement, and the cutting blade block 5 crushes and cuts the soil during rotation. In the process of the cutting blade block 5 moving forward with the traction device, the soil can not only be turned up, so that the deep plow bottom layer is brought up, but also the number of soil crushing times can be increased during the rotation process. The position of the cutting blade block 5 changes continuously during the rotation process, so that the soil can be fully cut and crushed, and the plow bottom layer brought up can be crushed.

[0045] S3: After completing a single pass of cutting, clean up the stones and proceed to the next pass of repair work. Collect the stones in the soil during the movement process, which improves the cleanliness of the soil and reduces the workload of removing impurities from the soil in the later stage.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
