[0043] As Figures 1 to 11 shown, the integrated device for preparing gravel slip zone soil of the embodiment of the present invention includes a crushing device 100, a rotary grinding device 200, a rotary screening device 300, a spiral drying device 400, and a moisture content preparation device 500.

The driving rotating shaft 11 can drive the screening cylinder 9 to rotate, so that the soil material in the screening cylinder 9 can be screened through the annular screen 10. A first discharge door 13 is arranged on the bottom plate of the screening cylinder 9 for discharging materials to the spiral drying device 400.

[0047] Among them, the spiral drying device 400 includes a drying cylinder 14 and a spiral heating plate 15 arranged inside the drying cylinder 14. The drying cylinder 14 is arranged below the screening cylinder 9. The driving rotating shaft 11 passes through the drying cylinder 14 and is rotationally matched with the bottom plate of the drying cylinder 14. The spiral heating plate 15 is fixedly installed on the driving rotating shaft 11. That is to say, the soil material screened by the rotary screening device 300 can fall into the drying cylinder 14 through the first discharge door 13. The driving rotating shaft 11 can drive the spiral heating plate 15 to rotate, so as to realize the drying treatment of the soil material in the drying cylinder 14. When the driving rotating shaft 11 rotates, since there is no contact between the drying cylinder 14 and the screening cylinder 9, the drying cylinder 14 will not rotate with the driving rotating shaft 11.

The driving rotating shaft 11 can drive the spiral stirring blade 18 to rotate, so as to uniformly stir the soil material and water in the preparation cylinder 17 and realize the moisture content preparation of the soil material.

[0049] Thus, the soil mixing and matching integrated device for crushed stone slip zone soil in the embodiment of the present invention can realize the integrated operation of crushing, grinding, screening, drying and moisture content preparation of crushed stone slip zone soil, effectively improving the working efficiency of soil mixing and matching of crushed stone slip zone soil.

[0050] Specifically, the integrated device for preparing gravel slip zone soil also includes a PLC controller (not shown in the figure), and the PLC controller is electrically connected to the crushing device 100, the rotary grinding device 200, the rotary screening device 300, the spiral drying device 400, and the moisture content preparation device 500 respectively.

[0051] In some embodiments of the present invention, the crushing device 100 further includes an L-shaped mounting plate 20 and a vibration mechanism 26 provided on the L-shaped mounting plate 20. The vibration mechanism 26 is drivingly connected to the crushing cylinder 1.

[0054] Among them, the flipping device includes two arc-shaped plates 23 arranged in parallel. Arc-shaped slide rails are respectively provided on the outer sides of the arc-shaped plates 23, and each arc-shaped slide rail is slidably matched with two pulleys 24 respectively. Each pulley 24 is respectively installed on a support column 25, and each support column 25 is fixedly installed on the rotating platform 22. The L-shaped mounting plate 20 is respectively connected and fixed to the inner sides of the two arc-shaped plates 23. An arc-shaped plate drive mechanism (not shown in the figure) for driving the arc-shaped plate 23 to slide along the corresponding pulley 24 is also provided on the rotating platform 22, so that the L-shaped mounting plate 20 can be flipped by 90 degrees.

[0055] That is, the rotation driving motor can drive the rotation of the rotating platform 22, thereby driving the equipment arranged on the rotating platform 22 to rotate, which is convenient for the operator to load materials into the crushing cylinder 1 in different directions. Before crushing, the arc plate driving mechanism is used to drive the arc plate 23 to turn over, so that the crushing cylinder 1 is in a vertical state. Then, the hammering mechanism 2 is used to hammer and crush the soil material in the crushing cylinder 1. During the hammering and crushing process, the vibration mechanism 26 can be used to drive the crushing cylinder 1 to vibrate intermittently, so as to ensure that the soil material in the crushing cylinder 1 is fully crushed. When the soil material in the crushing cylinder 1 is fully crushed, the arc plate driving mechanism is used to drive the arc plate 23 to turn over, so that the crushing cylinder 1 is in a horizontal state, which is convenient for feeding the material into the vibrating disk 4 through the spiral discharging mechanism 3.

[0056] In some embodiments of the present invention, the hammering mechanism 2 includes a flange 201. A plurality of telescopic rods 202 are arranged on one side of the flange 201, and rubber hammers 203 are respectively connected to the telescopic ends of the telescopic rods 202.

A spiral discharging blade 303 is fixedly installed on the first rotating shaft 302, and the spiral discharging blade 303 extends from the first end to the second end of the first rotating shaft 302. The port of the second end of the discharging cylinder 301 is arranged above the vibrating disk 4.

[0058] When the soil material in the crushing cylinder 1 is hammered and crushed, the first rotating motor is used to drive the first rotating shaft 302 to rotate, and then drive the spiral discharging blade 303 to rotate in the crushing cylinder 1 and the discharging cylinder 301, so that the soil material in the crushing cylinder 1 can be conveyed outwards under the driving action of the spiral discharging blade 303 and finally conveyed into the vibrating disk 4. During the feeding process of the spiral discharging mechanism 3, the vibration mechanism 26 can be used to drive the crushing cylinder 1 to vibrate, so that the soil material in the crushing cylinder 1 enters the discharging cylinder 301 under the vibration action, which is convenient for feeding through the spiral discharging blade 303.

[0059] In some embodiments of the present invention, the rotary grinding device 200 further includes a support frame, which includes two lifting columns 27 and a connecting column 28.

That is to say, the second rotating motor can drive the second rotating shaft to rotate, so as to drive the grinding column 5 to rotate in the vibrating disk 4 through the second rotating shaft, and realize the grinding of the soil material in the vibrating disk 4.

[0061] Among them, the two lifting columns 27 have a lifting function, and the realization of the lifting function can be achieved by a cylinder or an oil cylinder. Through the lifting actions of the two lifting columns 27, the grinding column 5 can be driven to perform up-and-down lifting adjustment, so as to adjust the gap between the grinding column 5 and the bottom surface of the vibrating disk 4, and thus the soil material in the vibrating disk 4 can be ground according to actual usage requirements.

[0062] Specifically, the vibrating disk 4 is a cylindrical structure with an open upper end. The spiral rising feeding track 7 is fixedly arranged on the inner wall of the vibrating disk 4.
