A receiving groove is provided on the left shell wall of the carrier plate 71, and a scraper 72 for scraping the paving material is installed in the receiving groove by adjusting bolts. When the scraper 72 is assembled, the height between its bottom end and the ground can be adjusted according to the thickness requirement of the paving material. A moving groove is provided on the right shell wall of the carrier plate 71, and a slide rail is slidably connected in the moving groove, and an L-shaped slide plate 73 is fixedly connected to the right side of the slide rail. A plurality of distribution plates 74 for distributing the paving material are linearly distributed at the bottom of the L-shaped slide plate 73. A cleaning plate 10 for cleaning the adhered objects on the rolling roller 62 is installed above the L-shaped slide plate 73 by bolts. The cleaning plate 10 is arranged to scrape off the objects adhered to the rolling roller 62 after the rolling roller 62 rotates one circle, thereby ensuring the compaction effect of the rolling roller 62 on the road.

[0082] See attached Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of the present application, a rectangular through hole and a strip movable groove are provided on the vehicle body 12. The rectangular through hole is located directly below the discharge end of the auger conveying device 3, the strip movable groove is located on the left side of the rectangular through hole, and a movable plate is slidably connected in the strip movable groove.

[0083] The discharging mechanism 9 is composed of an adjusting arm 91, a straight plate 92, a bellows 93 and a fixed plate 94. The adjusting arm 91 is fixedly connected to the left end of the screw conveying shaft 34, and a rod body is fixedly connected to the side wall of the adjusting arm 91. The screw conveying shaft 34 drives the adjusting arm 91 to move synchronously when rotating.

[0084] The straight plate 92 is fixedly connected to the top of the movable plate, and a motion groove is provided on the straight plate 92, and the left end of the rod body extends into the motion groove. When the adjusting arm 91 performs a rotational motion, the movement of the rod body arranged thereon in the motion groove drives the straight plate 92 to perform a linear reciprocating motion.

[0085] The bellows 93 is fixedly connected to the discharge end of the auger conveying device 3 by bolts, and the bottom end of the bellows 93 passes through the rectangular through hole. The setting of the bellows 93 can put the paving materials discharged by the auger conveying device 3 onto the ground. The movable plate and the bellows 93 are connected by the fixed plate 94, and the L-shaped slide plate 73 and the fixed plate 94 are connected by the bending plate. The adjusting arm 91 drives the straight plate 92 to reciprocate, thereby driving the movable plate to move, and the swing of the bottom end of the bellows 93 is realized through the fixed plate 94, so that the paving materials can be dispersed when they are put in. The setting of the bending plate enables the L-shaped slide plate 73 to move with the movement of the fixed plate 94, thereby driving the distribution plate 74 to further spread the dispersed paving materials.

[0086] See attached Fig.12 As shown, in one embodiment of the present application, during the road paving process, both sides of the road surface at the construction site can be unobstructed, and the road paving operation can be performed on the road surface by the equipment, or retaining walls can be piled on both sides of the road surface, and then the road surface between the retaining walls on both sides can be paved by the equipment. When the equipment is performing the road paving operation on the road surface, the layered paving operation of the road can be realized through the repetitive operation of the equipment. The design requirements of the retaining walls on both sides are that the upper part of the retaining wall is about 2m-3m, the height is about 2m, and the slopes on both sides are 1:1.

[0087] The present invention provides a laying method for a laying device for recycling waste soil, the method comprising the following steps:

[0088] Step 1: Material loading. Material loading consists of three steps: loading, shocking and generating cementitious materials.

[0089] The first step is loading: first, the equipment is driven to the location of the landfill by a transport vehicle 1, and then the soil in the landfill is loaded into the hopper 2 by an excavator or other loading equipment, and the cement and ultrafine cement used to generate the cementitious material are placed in proportion into the storage box 42 for storage, wherein the raw materials of the cementitious material are placed after the hopper 2 completes the material loading.

[0090] The second step is to vibrate the material: during the loading process, the conveying motor 33 in the auger conveying device 3 is started by the external control device to drive the screw conveying shaft 34 to move in the reverse direction. During the reverse movement of the screw conveying shaft 34, the discharging mechanism 9, the transmission assembly 13 and the blocking mechanism 14 are synchronously driven to operate. Among them, during the reverse movement of the blocking mechanism 14, the gear 141 engages with the front end teeth 1422 in the rack 142. The front end teeth 1422 are always in a disengaged state with the gear 141 under the cooperation of the corresponding spring telescopic rod 1423, and then the rack 142 drives the blocking plate 144 to remain unchanged through the curved frame 143, so as to achieve the blocking of the material drop channel 8. At this time, the soil material falling into the hopper 2 is always in the hopper 2 and has not entered the auger conveying device 3. The toothed chain member 132 in the transmission assembly 13 causes the reciprocating screw 131 to move under the action of the rotation of the screw conveying shaft 34. During the movement, the reciprocating screw 131 synchronously drives the disc 55 of the driving member in the vibration mechanism 5 to rotate synchronously. During the rotation of the disc 55, the horizontal plate 56 movably connected to the guide column 57 performs longitudinal reciprocating movement. During the longitudinal reciprocating movement, the horizontal plate 56 drives the multiple connecting frames 54 to move synchronously, and the connecting frames 54 are loaded with the joint plate 53 in the vibration member. The joint plate 53 performs longitudinal reciprocating movement with the connecting frame 54, so that the multiple knocking rods 52 arranged thereon perform synchronous movement. The knocking rods 52 realize knocking and vibration on the hopper 2 when performing longitudinal reciprocating movement, thereby solidifying the soil materials falling into the hopper 2.

[0091] By coordinating the loading and the shaking, it is ensured that the soil material is loaded in the hopper 2 to the maximum extent.

[0092] The one-way valve provided on the discharge pipe of the auxiliary material delivery mechanism 4 is in a closed state under normal conditions, and the operation of the transmission assembly 13 during the soil material feeding process of the product does not cause the cementitious material to be quantitatively added to the auger conveying device 3. At this time, since there is no material in the auger conveying device 3, the movement of the discharge mechanism 9 and the paving assembly 7 along with the movement of the screw conveying shaft 34 will not cause any adverse effects.

[0093] The third step is the generation of cementitious materials: after the cement and superfine cement in the storage box 42 are added in proportion, the stirring assembly 48 is started to operate, thereby stirring and mixing the materials in the storage box 42 to generate cementitious materials.

[0094] Step 2: Material transfer. When the soil material is loaded into the hopper 2 and the cementitious material is placed into the storage box 42, the transport vehicle 1 transports the loaded soil material and cementitious material from the loading site to the construction site.

[0095] Step 3: Generation of paving materials. The generation of paving materials consists of crushing soil and outputting cementitious materials.

[0096] When the transport vehicle 1 arrives at the predetermined construction site, the transport vehicle 1 is temporarily parked first, and the paving material needs to be prepared first, and then the transport vehicle 1 is started to move at a uniform speed after the material is discharged, so as to spread the paving material on the road.

[0097] For the crushing output of soil materials, the crushing mechanism 15 is first started by the external control device to crush the soil materials that are falling and output, and then the conveying motor 33 in the auger conveying device 3 is started to drive the screw conveying shaft 34 to move forward. The forward movement of the screw conveying shaft 34 causes the gear 141 in the blocking mechanism 14 to engage with the end teeth 1422 at the front end position of the rack 142. At this time, under the action of the spring telescopic rod 1423, the long rack 1421 in the rack 142 moves, and then the gear 141 and the long rack 1421 are meshed and transmitted, so that the rack 142 moves in the opposite direction. The blocking of the blocking plate 144 is opened by the curved frame 143. When the gear 141 is meshed and contacted with the end teeth 1422 at the rear end position of the rack 142, the gear 141 and the rack 142 are disengaged by the corresponding spring telescopic rod 1423. At this time, the opened blocking plate 144 is in a long-term open state, so that the soil in the hopper 2 can continuously enter the auger conveying equipment 3 through the drop channel 8 after being crushed.

[0098] When the blocking mechanism 14 is opened, the vibration mechanism 5 realizes continuous knocking and vibration of the hopper 2 under the action of the transmission assembly 13. With the help of vibration, the material inside the hopper 2 continuously and stably falls into the interior of the auger conveying device 3 through the material dropping channel 8, and is continuously mixed and conveyed from right to left as the screw conveying shaft 34 runs.

[0099] When the paving material is produced, the cementitious material stored in the storage box 42 can be automatically input into the quantitative box 43 through the discharge pipe and the one-way valve under the action of gravity.

[0100] The movement of the screw conveying shaft 34 synchronously drives the transmission assembly 13 to move, thereby causing the adjustment plate 46 in the auxiliary material feeding mechanism 4 to reciprocate horizontally under the action of the cross rod 45. The horizontal adjustment of the cross rod 45 drives the pushing plate 44 to reciprocate.

[0101] When the pushing plate 44 moves to the left, it removes the obstruction to the discharge pipe, and the cementitious material in the storage box 42 is put into the quantitative box 43 through the one-way valve. When the pushing plate 44 moves to the right, the air pump body 49 operates in the synchronous process, thereby blowing air into the quantitative box 43 through the cross rod 45, so as to realize the air delivery of the cementitious material in the quantitative box 43. Due to the setting of the one-way valve, the cementitious material can only be discharged from the material delivery pipe 47. After the cementitious material is input into the auger conveying device 3 through the material delivery pipe 47, it is mixed with the conveyed soil material, and the paving material is generated under the mixing and conveying action of the auger conveying device 3. The pushing plate 44 further pushes the cementitious material during the movement, thereby improving the efficiency of the cementitious material being conveyed.

[0102] Step 4: The paving material is unloaded and distributed. The paving material generated by the mixed transportation of the auger conveying equipment 3 is discharged from the discharging end. During the movement of the spiral conveying shaft 34, the adjusting arm 91 in the discharging mechanism 9 is synchronously driven to perform circular motion, so that the straight plate 92 moves. Since the straight plate 92 is loaded on the movable plate, the straight plate 92 performs linear reciprocating motion with the movement of the adjusting arm 91. The movement of the movable plate synchronously drives the fixed plate 94 to move, so that the bottom end of the bellows 93 swings, so that the paving material is prevented from piling up during the unloading process. During the movement of the fixed plate 94, the L-shaped slide plate 73 in the paving assembly 7 is synchronously driven to reciprocate, and the paving material discharged from the bellows 93 is further distributed through the distribution plate 74 distributed on the L-shaped slide plate 73, thereby reducing the burden of scraping the paving material in the later stage and ensuring the effect of scraping it.

[0103] Step 5: Rolling and paving. When the paving material falls on the ground, the transport vehicle 1 starts to move at a constant speed to spread the paving material on the ground. The movement of the transport vehicle 1 causes the scraper 72 in the paving assembly 7 to scrape the paved material after spreading, and under the continuous movement of the transport vehicle 1, the rolling roller 62 in the rolling assembly 6 rolls the scraped paving material, thereby paving the road. When the rolling roller 62 moves one circle, the cleaning plate 10 scrapes and cleans the material adhered to it to ensure the rolling effect of the rolling roller 62 on the paving material.
