[0024] See attached Figure 1-7 The soil repair loosening device comprises a top plate 1, side plates 2 are symmetrically fixedly arranged at the bottom of both sides of the top plate 1, a plurality of vertical plates 3 are arranged equidistantly between the two side plates, a vertical shaft sleeve 4 is fixedly arranged at the front end of the vertical plate 3, the upper end of the shaft sleeve 4 is rotatably connected to the bottom of the top plate, a vertical shaft 5 is arranged in the shaft sleeve, a soil shovel 6 is fixedly installed at the lower end of the vertical shaft 5, a first through hole 7 is opened at the position of the top plate 1 corresponding to the vertical shaft 5, the upper end of the vertical shaft 5 passes through the corresponding first through hole 7 and is located at the upper side of the top plate, an internal threaded sleeve 8 is fixedly installed at the upper end of the first through hole 7, and the vertical shaft 5 is fixedly installed at the upper end of the vertical shaft 5. An external thread is provided at the upper end of the shaft, and the external threaded part at the upper end of the vertical shaft is threadedly matched with the internal threaded sleeve 8. The upper end of the vertical shaft passes through the internal threaded sleeve and is connected to one end of the rocker arm 9. A reciprocating drive device is arranged at the upper part of the top plate corresponding to the other end of the rocker arm. The other end of the rocker arm 9 is connected to the reciprocating drive device. The reciprocating drive device drives the vertical shaft to rotate reciprocatingly through the rocker arm. At this time, the vertical shaft realizes up and down reciprocating movement by cooperating with the thread of the internal threaded sleeve 8, thereby driving the soil shovel to move up and down. At this time, the soil shovel also swings synchronously, which can better shovel the soil layer.

[0025] A vertical bar 10 is fixedly installed on the upper rear side of the vertical plate 3, and an arc-shaped second through hole 11 is provided at the position of the top plate corresponding to the vertical bar. Limiting plates are fixedly installed at the upper and lower ends of the second through hole on the vertical bar. The limiting plates fit the top plate. The upper end of the vertical bar 10 passes through the second through hole 11 and is located on the upper side of the top plate. The upper end of the vertical bar 10 is fixedly connected to one end of the cross bar 12. A reciprocating drive device is also provided at the other end of the cross bar 12 at the upper part of the top plate. The other end of the cross bar 12 is connected to the reciprocating drive device. The reciprocating drive device drives the vertical plate to swing back and forth around the vertical axis 5 through the cross bar and the vertical bar. The vertical bar moves back and forth along the arc-shaped second through hole 11. Adjacent vertical plates can achieve uninterrupted approach and distance from each other. When two adjacent vertical plates approach each other, the soil blocks between them are crushed to achieve a loosening effect. The limiting plates can improve the installation stability of the vertical bars and the installation stability of the vertical plates at the same time.

[0026] The wave plates 13 are symmetrically arranged on both sides of the vertical plate 3, the front end of the wave plates 13 is fixedly connected to the corresponding side of the vertical plate 3, the wave plates themselves have a certain elasticity, and are preferably made of elastic steel plates, and there is a gap between the rear end of the wave plates and the corresponding side of the vertical plate. Through the arrangement of the wave plates, when two adjacent vertical plates are close to each other, the uneven surface of the wave plates can better crush the soil blocks, and when encountering hard soil blocks, the elasticity of the wave plates themselves can also play a buffering role, which can achieve a crushing effect.

[0027] A fixing frame 14 is fixedly installed on the upper part of the top plate, and the upper side of the fixing frame 14 is connected to a traction frame 15 through a lifting device. The traction frame is fixed to the rear end of a tractor, not shown in the figure. The device is towed by the tractor, and the height of the fixing frame is controlled by the lifting device, so that the side plates and the soil shovel can be lowered during loosening work, and the side plates and the soil shovel can be raised during non-working.

[0028] The lifting device includes a plurality of parallel connecting rods 16, the two ends of the connecting rod 16 are respectively hingedly connected to the fixed frame and the traction frame through axle seats, the traction frame and the side of the connecting rod 16 are hingedly connected through a hydraulic rod, and the angle between the connecting rod and the traction frame can be adjusted by extending and retracting the hydraulic rod, thereby adjusting the height of the fixed frame.

[0029] The reciprocating drive device includes a guide rail 17 installed on the top of the top plate, a slider 18 is installed at the position corresponding to the vertical plate on the guide rail, a lever 19 is fixedly installed on the upper end of the slider, an eccentric wheel 20 is arranged on the side of the slider corresponding to the top of the top plate, the eccentric position of the eccentric wheel is hingedly connected to the corresponding side of the slider through a driving rod 21, the eccentric wheel is a driven gear and is connected to the driving gear on the driving motor 22, the driving motor is fixedly installed on the upper part of the top plate through a motor frame, a long hole 23 is provided at the bottom of the other end of the swing rod, and the lever 19 corresponding to the swing rod is inserted into the long hole, and a long groove 24 is provided at the bottom of the other end of the cross bar 12, and the upper end of the lever corresponding to the cross bar is inserted into the corresponding long groove. The working of the driving motor cooperates with the eccentric wheel and the driving rod to drive the slider to slide reciprocatingly on the guide rail.

[0030] The rear end of the fixed frame 14 is provided with a soil crushing roller 25, the shaft of which is connected to a rotary drive device, which is a prior art and will not be described in detail herein. The loose soil can be further broken up by the arrangement of the soil crushing roller, so as to facilitate the planting of plants in the later stage.

[0031] A vertical blade 26 is arranged on the front side of the shaft sleeve 4, and the blade of the blade 26 faces forward. This design can reduce the resistance when the device moves forward.

[0032] A soil pressing plate 27 inclined toward the upper front side is fixedly installed at the front end of the top plate. This design ensures that the top plate is on the upper side of the ground during operation, which is convenient for the operation of the staff.

[0033] Working principle: when in use, the device is towed by a tractor. After reaching the working area, the side plates and the soil shovel are lowered as a whole. The side plates and the soil shovel are slowly inserted into the soil layer, and the vertical plates are also inserted into the soil layer. The reciprocating drive device drives the soil shovel to move back and forth up and down. At this time, the soil shovel can initially crush the soil blocks in the up and down directions. The reciprocating drive device can also drive the adjacent vertical plates to approach and move away from each other. When two adjacent vertical plates approach each other, the soil blocks between them will be crushed again. Through two squeezings in different directions, large pieces of soil can be crushed, which can better deal with compacted soil blocks. This loosening method can reduce damage to the equipment. The side plates also have the function of controlling the loosening range. When working, only the soil in the range between the two side plates is loosened, which can better control the loosening range. The device can accurately loosen the soil in a long strip area. Through the staff operating the tractor, multiple long strip areas with loosened soil can be formed. The multiple long strip areas are parallel to each other, and an area without loosening soil is retained between two adjacent long strip areas. The long strip area is used as a planting area, and the area without loosening soil can be used as a ridge. The ridge can be automatically retained during the loosening process, and people can enter the field through the ridge with relatively hard soil to apply fertilizers, spray pesticides, etc.
