DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0018] like Figure 3 , Figure 4 As shown, the carrier 2 slides vertically at the bottom of the vehicle body 1 through a slider and a slide rail, the first oil cylinder 11 is vertically installed on the surface of the vehicle body 1, the telescopic end of the first oil cylinder 11 is connected to the carrier 2, the rotary tillage tool 3 is rotatably installed at the bottom of the carrier 2, the second motor 31 is installed on the surface of the carrier 2, and the second motor 31 is connected to the rotary tillage tool 3 through a belt drive; like Figure 3 , Figure 4 , Figure 6As shown, the humidity control assembly 4 includes a cover plate 41, which is arranged at the rear of the carrier 2. A plurality of water spray strips 42 are arranged at the bottom of the cover plate 41. The water spray strips 42 are located behind the rotary tillage tool 3. There are gaps between the water spray strips 42 for conducting soil. The water spray strips 42 include a plate body 421. The cross section of the plate body 421 is a pointed cone. The pointed cone edge of the front of the plate body 421 points to the rotary tillage tool 3. The rear of the plate body 421 has a groove 423. The plate body 421 has a cavity 422 inside. The cavity 422 is connected to a water pipe 45. The water pipe 45 is connected to a water supply source. A plurality of nozzles 424 connected to the cavity 422 are arranged in the groove 423. According to the requirements of the test project, when it is necessary to increase the soil moisture, during the movement of the vehicle body 1, the first oil cylinder 11 is opened and extended, so that the carrier 2 drives the rotary tillage tool 3 to descend, and the second motor 31 is opened to drive the rotary tillage tool 3 to rotate. The rotary tillage tool 3 tills and loosens the soil in the soil trough, and the water spraying strips 42 are evenly inserted into the soil. The broken soil rotated by the rotary tillage tool 3 is conducted through the gaps between the water spraying strips 42. The external water supply source guides water into each cavity 422 through the water pipe 45. The water is sprayed backwards by the nozzle 424. The sprayed water is mixed with the rotated soil, which can quickly and evenly reduce the soil moisture.

[0019] like Figure 4 As shown, the top of the cover plate 41 is rotatably connected to the carrier 2, a handle 43 is extended and fixed on the top of the cover plate 41, a groove 46 is provided on the surface of the handle 43, a second oil cylinder 44 is installed on the surface of the carrier 2, and buckle columns 47 distributed up and down are fixed to the telescopic end of the second oil cylinder 44, the telescopic end of the second oil cylinder 44 passes through the groove 46, and the buckle columns 47 are respectively attached to the upper and lower surfaces of the cover plate 41; like Figure 5 As shown, the water control valve 7 includes a valve housing 71, the valve housing 71 is fixed to the cover plate 41, a valve block 72 is elastically slidable in the valve housing 71 through a spring, the bottom of the valve block 72 passes through the valve housing 71, fixed valve ports 73 are oppositely opened on both sides of the valve housing 71, the fixed valve ports 73 are respectively connected to the water pipe 45 and the water supply source, and a movable valve port 74 is opened on the surface of the valve block 72; When there is no need to adjust the soil moisture, the second oil cylinder 44 is opened to extend, and the handle 43 is pressed down through the buckle column 47, so that the cover plate 41 drives each water spray strip 42 to be tilted up, and the water spray strip 42 does not contact the soil, thereby reducing the resistance of the vehicle body 1 during the movement. When the cover plate 41 is tilted up, the valve block 72 does not contact the carrier 2, and the elastic force causes the valve block 72 to extend out of the valve housing 71, and the movable valve port 74 is misaligned with the fixed valve port 73, thereby cutting off the water supply line.

[0020] When adjusting soil moisture, the second oil cylinder 44 is opened and contracted, and the handle 43 is pulled up through the buckle column 47 to make the cover plate 41 descend and fit the surface of the carrier 2, and the water spray strip 42 descends and inserts into the soil. The valve block 72 is squeezed and contracted by the carrier 2 to align the fixed valve port 73 with the movable valve port 74, and the water channel is connected. The external water supply source guides water into each water spray strip 42 through the fixed valve port 73, the movable valve port 74, and the water pipe 45 to adjust the soil moisture.

[0021] like Figure 7 , Figure 8 As shown, the soil compacting assembly 6 includes a pressing roller 61, which is rotatably connected to a hanger 62. A bracket 67 extending backward is fixed on the surface of the carrier 2. The hanger 62 is connected to the bracket 67 through a regulating assembly. The soil leveling roller 5 is rotatably arranged in front of the pressing roller 61. The third motor 51 is installed on the surface of the hanger 62. The third motor 51 is connected to the soil leveling roller 5 through a belt drive. The edge of the soil leveling roller 5 has a plurality of bars, and the bars contact the surface of the pressing roller 61. When implementing soil state adjustment, the bracket 67 drives the soil leveling roller 5 and the pressure roller 61 to follow the carrier 2 to descend, and the third motor 51 is turned on to drive the soil leveling roller 5 to rotate, so that the bar at the bottom of the soil leveling roller 5 rotates forward, and the bar flattens the protruding broken soil to make the soil surface in the soil trough relatively flat. The pressure roller 61 presses down on the soil surface to compact the soil to meet the test requirements. At the same time, the rotating soil leveling roller 5 can peel off the soil adhered to the surface of the pressure roller 61 to avoid excessive clay on the surface of the pressure roller 61 affecting the compaction work.

[0022] like Figure 7 As shown, the regulating component includes a seat frame 63, a third oil cylinder 68 is symmetrically installed on both sides of a bracket 67, a slide groove 69 is symmetrically provided on both sides of the seat frame 63, a slider 610 is slidable left and right in the slide groove 69, the telescopic end of the third oil cylinder 68 is rotatably connected to the slider 610, and guide pillars 64 extending upward are fixed at both ends of the hanger 62, and the guide pillars 64 slide through the seat frame 63, and a top plate 65 is elastically connected to the top of the seat frame 63 through a spring, and a pressure sensor 66 is provided at the bottom of the top plate 65, and the top of the guide pillar 64 squeezes and contacts the pressure sensor 66, and the pressure sensor 66 is connected to the third oil cylinder 68 through a controller; When the soil compaction work is carried out, the pressure roller 61 is pressed down to contact the soil surface. According to the compaction strength requirement, the downward pressure of the two third oil cylinders 68 is adjusted through the controller. The two third oil cylinders 68 are extended to push the seat frame 63 down, and the guide column 64 slides through the seat frame 63. Through the tension of the spring, the guide column 64, the hanger 62, and the pressure roller 61 are pressed down to press the soil. The pressure sensor 66 is squeezed by the guide column 64 to feedback the pressure value to the controller. When the two pressure sensors 66 monitor that the pressure at both ends of the pressure roller 61 is uneven, the expansion and contraction amount of the two third oil cylinders 68 is adjusted to make the pressure at both ends of the pressure roller 61 adaptively adjusted to make the soil compaction more uniform.
