Description

Technical Field

[0001] The invention relates to the technical field of soil restoration, in particular to a highly efficient garden soil restoration device. Background Art

[0002] Soil remediation is divided into chemical remediation, biological remediation and physical remediation. Most traditional remediation methods use chemical remediation. Some soil remediation particles are sprinkled on the soil that needs to be repaired, and the soil is repaired by the soil remediation particles to change the heavy metal content in the soil so that its content can meet the standard for plant growth. Some soils also need to be biologically repaired after chemical remediation. For example, chemically repaired soil usually has soil compaction, resulting in soil poverty, imbalance of microorganisms, and low air content. At this time, the soil is still not suitable for planting vegetation. At this time, it is necessary to cover the soil and fertilize it to repair the soil, using farmyard manure, straw debris, etc. as remediation agents. This type of remediation agent can not only serve as a carrier to provide a living environment for microbial flora, but also increase the air content in the soil. After a period of microbial decomposition, the soil can be repaired, so that the planted vegetation can survive, and the speed of forest formation of tree vegetation in the garden can be accelerated.

When the screening mechanism is working, the soil blocks can be pushed out horizontally and discharged from the first discharge nozzle, and the soil blocks can be preliminarily crushed during pushing. The discharged soil blocks fall into the roller screen from the first discharge nozzle, and the roller screen is used to perform secondary crushing and screening on the soil blocks. The broken soil crushed by the screening mechanism falls into the mixing mechanism through the screen plate, and the small soil blocks screened fall into the roller screen through the second discharge nozzle.

[0027] 2. The screening mechanism provided in the present invention, when in use, drives one of the transverse axes to rotate through the rotation of the reduction motor, and the multiple transverse axes are linked by the first gear, so that the multiple transverse axes can drive the spiral blades with different spiral directions to rotate, and because the two adjacent spiral blades rotate in opposite directions, the soil to be repaired can be jointly pushed to move horizontally, and small particles of soil can fall from the gaps between the spiral blades, thereby achieving preliminary screening of the compacted soil blocks in the soil. There are still larger soil blocks in the screened soil, and the soil blocks fall into the frame, and when the transverse axis rotates, it drives the first bevel gear to rotate the second bevel gear, and the rotation of the second bevel gear drives the transmission shaft to make the rocker arm do circular motion. When the rocker arm moves, it drives the first rectangular frame to reciprocate horizontally. At this time, the first rectangular frame drives the transmission rod to make the transverse plate reciprocate, so that the screening effect of the soil can be achieved under the multiple guide plates, and the crushing knife fixed on the transverse plate can cooperate with the guide plate to cut the soil blocks, so as to further crush the soil.

[0028] 3. The mixing mechanism provided in the present invention, when in use, the first motor drives the brake rod to make the shaft pin do circular motion, and the shaft pin drives the second rectangular frame to swing the second gear when it moves, and the swing of the second gear drives the first gear ring to swing the circular ring back and forth, so that the soil and the repair agent can be mixed by using two screens, and the soil and the repair agent first fall into the upper screen, and then a part of the soil and the repair agent falls through the screen, and the other part of the soil and the repair agent falls through the mixing part, so that the soil and the repair agent can be fully mixed when the screen 17 swings back and forth.

[0029] 4. The driving mechanism provided in the present invention, when in use, starts the second motor to drive the worm to rotate the worm wheel, and when the worm wheel rotates, it drives the rotating shaft to rotate the third gear, and the third gear rotates to drive the second gear ring to rotate the roller screen, and when the roller screen rotates, it can stir the soil blocks falling from the first discharge nozzle and the second discharge nozzle, and when stirring, the soil blocks are pushed to a high place in the roller screen through the material-diverting plate, and hit the edge blocks when sliding down, so that the larger soil blocks can be crushed, and when the roller screen rotates, the support frame supporting it drives the casing to rotate, and when the casing rotates, it drives the outer gear ring to rotate the gear shaft, and when the gear shaft rotates, it drives the fourth gear to rotate through its meshing part, and the two meshing parts on the gear shaft have different numbers of teeth, which can play a speed-increasing effect between the outer gear ring and the fourth gear, so the fourth gear rotates and drives the supporting shaft to rotate the multiple circular plates at a speed greater than the roller screen, and when the circular plate rotates, it drives the crushing plate and the crushing teeth to impact and crush the soil blocks falling from the material-diverting plate, so that the soil blocks can be fully crushed.

[0062] The side wall of the shell 5 is rotatably connected with a sleeve 52 through a rolling bearing, and the side wall of the sleeve 52 is fixedly connected to one of the support frames. The sleeve 52 is rotatably connected to the shaft wall of the support shaft 44 through a sealed bearing. One end of the sleeve 52 is located in the shell 5 and is fixedly connected with an outer gear ring 50. A gear shaft 49 is arranged in the shell 5. Two meshing parts are arranged on the shaft wall of the gear shaft 49, one of which meshes with the outer gear ring 50, and the other meshes with a fourth gear 51. The fourth gear 51 is fixed on the shaft wall of the support shaft 44. A plurality of circular plates are fixedly connected to the shaft wall of the support shaft 44. The edges of the plurality of circular plates are rotatably connected with crushing plates 47 through pins. The side wall of the crushing plate 47 is fixedly connected with crushing teeth 48. A plurality of evenly distributed material-pickling plates 53 and a plurality of edge blocks 54 are fixedly connected to the inner side of the roller screen 9.

[0063] The present invention is provided with a driving mechanism. When in use, the second motor 40 is started to drive the worm 46 to rotate the worm wheel 45. When the worm wheel 45 rotates, it drives the rotating shaft to rotate the third gear 38. The rotation of the third gear 38 drives the second gear ring 55 to rotate the roller screen 9. When the roller screen 9 rotates, it can stir the soil blocks falling from the first discharge nozzle 4 and the second discharge nozzle 13. When stirring, the soil blocks are moved to a high place in the roller screen 9 through the material-moving plate 53, and hit the edge block 54 when sliding down, so that the larger soil blocks can be crushed;

[0064] When the roller screen 9 rotates, the support frame drives the sleeve 52 to rotate. When the sleeve 52 rotates, it drives the outer gear ring 50 to rotate the gear shaft 49. When the gear shaft 49 rotates, it drives the fourth gear 51 to rotate through its meshing portion. The two meshing portions on the gear shaft 49 have different numbers of teeth, and the outer gear ring 50 and the fourth gear 51 can have a speed-increasing effect. Therefore, the fourth gear 51 rotates and drives the support shaft 44 to rotate multiple circular plates at a speed greater than the roller screen 9. When the circular plates rotate, they drive the crushing plates 47 and the crushing teeth 48 to impact and crush the soil blocks falling from the material-selecting plate 53, so that the soil blocks can be fully crushed. In addition, the electric push rod can push the roller screen 9 to tilt, and the angle can be adjusted at any time. By adjusting the tilt angle, the moving speed of the soil blocks in the roller screen 9 can be controlled, that is, when the roller screen 9 is laid flat, the moving speed of the soil blocks is the slowest, and the crushing teeth 48 can be fully utilized for crushing. When the roller screen 9 is tilted, the moving speed of the protrusions can be increased, and the stones and other debris that cannot be crushed can be discharged.
