DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 This embodiment discloses a conveying device for in-situ mixing of solid waste for improving foundation, including a soil crushing component and a soil turning component.

[0038] The soil crushing assembly includes a connecting plate 3, side plates 4 are fixed at both ends of the connecting plate 3 in the length direction, a first rotating shaft 1 is installed between the two side plates 4 through a bearing, a plurality of crushing knives 2 are fixedly installed on the first rotating shaft 1, and the crushing knives 2 are arranged at equal intervals along the length direction of the first rotating shaft 1, and the connecting plate 3 is bent downward near the first rotating shaft 1.

[0039] The soil-turning assembly includes a receiving plate 10 fixed between two side plates 4, both ends of the receiving plate 10 in the width direction are bent upward, and a second rotating shaft 13 and a third rotating shaft 14 are installed between the two side plates 4 through bearings. The second rotating shaft 13 and the third rotating shaft 14 are arranged in parallel, and the second rotating shaft 13 and the third rotating shaft 14 are located at the same height. Spiral blades are fixedly installed on the second rotating shaft 13 and the third rotating shaft 14. The spiral blades on the second rotating shaft 13 and the spiral blades on the third rotating shaft 14 are both located above the receiving plate 10, and a mud outlet hole 11 arranged along the length direction of the receiving plate 10 is opened on the bottom side of the receiving plate 10.

[0040] The position of the accommodating plate 10 close to the first rotating shaft 1 and the position of the connecting plate 3 far from the first rotating shaft 1 are fixedly connected, and the lowest point of the bottom side of the accommodating plate 10 is higher than the lowest point of the bottom side of the connecting plate 3 .

[0041] Furthermore, the difference between the height of the lowest point on the bottom side of the receiving plate 10 and the height of the lowest point on the bottom side of the connecting plate 3 is 5.0-30.0 cm.

[0042] Furthermore, the length direction of the connecting plate 3 is parallel to the length direction of the accommodating plate 10 .

[0043] The working process and principle of this embodiment are:

[0044] The staff lays solid waste on the road surface. The conveying device for in-situ mixing of the solid waste improved foundation is installed on an external traction vehicle through an external three-point suspension device. The height of the conveying device for in-situ mixing of the solid waste improved foundation is adjustable, and the external traction vehicle drives the conveying device for in-situ mixing of the solid waste improved foundation to move.

[0045] The first rotating shaft 1, the second rotating shaft 13 and the third rotating shaft 14 are all driven to rotate by an external power mechanism. The rotation direction of the spiral blade on the second rotating shaft 13 is opposite to the rotation direction of the spiral blade on the third rotating shaft 14. The first rotating shaft 1 drives the crushing knife 2 to rotate, and the rotating crushing knife 2 enters the soil. The rotating crushing knife 2 makes the solid waste and the crushed soil fall on the receiving plate 10. The spiral blade on the second rotating shaft 13 makes the solid waste and the soil on the receiving plate 10 accumulate close to one of the side plates 4, and then the accumulated solid waste and soil are pushed to the other side plate 4 by the spiral blade on the third rotating shaft 14 and accumulated. The solid waste and soil accumulated there are pushed by the spiral blade on the second rotating shaft 13. The spiral blades are removed, and the solid waste and soil on the receiving plate 10 are continuously accumulated and mixed during the horizontal movement, so that the solid waste is evenly distributed in the crushed soil, and the mixture of solid waste and soil on the receiving plate 10 falls to the ground through the mud outlet holes 11, and then the external compacting machinery compacts the mixture of solid waste and soil, and in the process of in-situ transporting the soil at the foundation, the foundation is improved by solid waste, the energy consumption of reciprocating soil transportation is reduced, and the construction period of foundation improvement is shortened. The in-situ mixing and conveying device for improving the foundation of solid waste improves the mixing effect of solid waste and soil, improves the construction quality, reduces the construction cost, ensures the strength of the foundation, and promotes the resource utilization of solid waste.

[0046] Furthermore, the solid waste and soil mixture on the receiving plate 10 falls to the ground through the mud outlet holes 11, thereby preventing the depression or protrusion of the foundation before improvement from affecting the flatness of the road surface after compaction.

[0047] Furthermore, an external power mechanism drives the first rotating shaft 1, the second rotating shaft 13 and the third rotating shaft 14 to rotate. The external power mechanism is an engine of a traction vehicle, and the engine realizes power transmission through a belt and pulley transmission assembly or a chain and sprocket transmission assembly.

[0048] Furthermore, the diameter of the solid waste is less than 40 mm.

[0049] Embodiment 2:

[0050] like Figure 2 , Figure 5 , Figure 8 , Fig. 9As shown, the present embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is substantially the same as that of the first embodiment, except that, a rope cloth assembly 7 is provided on the bottom side of the connecting plate 3 of the present embodiment, and the rope cloth assembly 7 comprises a mounting frame 76 vertically fixed on the bottom side of the connecting plate 3, and two guide wheels 71 are installed on one side of the mounting frame 76 corresponding to the accommodating plate 10 through bearings, and the two guide wheels 71 are respectively located at both ends of the length direction of the mounting frame 76, and the two guide wheels 71 are connected by a belt 73, and a driving mechanism 72 for driving one of the guide wheels 71 to rotate is installed on the mounting frame 76, and a plurality of rope drum support frames 74 are fixedly installed on the belt 73, and a rotating rope drum 75 is installed on each rope drum support frame 74, and a reinforcing rope is wound around each rope drum 75.

[0051] Among them, one end of the reinforcing rope on the rope drum 75 passes under the mud discharge hole 11.

[0052] Furthermore, the driving mechanism 72 is an electric motor or a hydraulic motor commonly used in the prior art.

[0053] The working process and principle of this embodiment are:

[0054] The staff makes one end of the reinforcing rope on each rope drum 75 pass under the mud outlet hole 11, and the solid waste and soil mixture falling from the mud outlet hole 11 is pressed on the reinforcing rope. The driving mechanism 72 drives the belt 73 to rotate through the guide wheel 71, and the rope drum 75 on the rope drum support frame 74 rotates synchronously with the belt 73. During the movement of the conveying device for in-situ mixing of the solid waste improved foundation, the reinforcing rope is arranged back and forth in the mixture of solid waste and soil. The solid waste in the soil increases the friction between the reinforcing rope and the soil, and the reinforcing rope increases the strength and stability of the compacted mixture of solid waste and soil.

[0055] Furthermore, the reinforcing rope is made of polyester fiber, nylon or polypropylene.

[0056] Embodiment three:

[0057] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, this embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is substantially the same as that of the second embodiment, except that a plurality of stacked fixed frame plates 12 are fixed to the bottom side of the receiving plate 10 of this embodiment, and the frame holes of the fixed frame plates 12 are arranged corresponding to the mud outlet holes 11.

[0058] The working process and principle of this embodiment are:

[0059] The staff adjusts the number of fixed frame plates 12 on the bottom side of the receiving plate 10 to adjust the paving thickness of the solid waste and soil mixture, thereby improving the applicability of the conveying device for in-situ mixing of the solid waste improved foundation.

[0060] Embodiment 4:

[0061] like Figure 2 , Figure 3 As shown, this embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is substantially the same as that of the third embodiment, except that, in this embodiment, one of the side panels 4 is provided with an opening 8, and the opening 8 is higher than the second rotating shaft 13 and the third rotating shaft 14.

[0062] The working process and principle of this embodiment are:

[0063] When there is too much solid waste and soil mixture on the receiving plate 10, the solid waste and soil mixture on the receiving plate 10 falls through the opening 8 to the outside of the opening 8, thereby ensuring the paving thickness of the solid waste and soil mixture and reducing the energy consumption of the conveying device for in-situ mixing of the solid waste improved foundation.

[0064] Embodiment five:

[0065] like Figure 3 As shown, the present embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is substantially the same as that of the fourth embodiment, except that, in the present embodiment, a material box 9 is installed at a position corresponding to the opening 8 on the side plate 4, and the material box 9 comprises a box body 91 fixed on the side plate 4, and the top and bottom sides of the box body 91 are both opened, and a rotatable opening and closing bottom plate 94 is installed on the bottom opening of the box body 91, and an elastic member 95 is installed on the side plate 4 to make the bottom plate 94 snap into the bottom opening of the box body 91, the opening 8 is connected to the inner cavity of the box body 91 or the opening 8 is located above the top opening of the box body 91, and a first permanent magnet 92 is fixed to the bottom of the outer side of the box body 91, and a second permanent magnet 93 is fixed to the position of the bottom plate 94 corresponding to the first permanent magnet 92.

[0066] Furthermore, the elastic member 95 is a spring or an elastic rod.

[0067] The working process and principle of this embodiment are:

[0068] When there is too much solid waste and soil mixture on the receiving plate 10, the solid waste and soil mixture on the receiving plate 10 falls into the box body 91 through the opening 8. When the force exerted by the solid waste and soil mixture in the box body 91 on the bottom plate 94 is greater than the magnetic attraction between the first permanent magnet 92 and the second permanent magnet 93, the bottom plate 94 rotates downward, and the elastic member 95 accumulates elastic potential energy. The solid waste and soil mixture in the box body 91 falls downward to the ground, and then the elastic member 95 causes the bottom plate 94 to rotate upward, and the bottom plate 94 is buckled on the opening on the bottom side of the box body 91.

[0069] The material box 9 allows the excessive solid waste and soil mixture on the receiving plate 10 to be gathered into a pile after leaving the opening 8. The piled solid waste and soil mixture is convenient for workers to clean up, thereby reducing the workload of the workers.

[0070] Embodiment six:

[0071] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is roughly the same as that of the first embodiment, except that it also includes a compaction component 6. The compaction component 6 of this embodiment includes a pressure wheel 66, and support rods 67 are installed at both ends of the pressure wheel 66 through bearings, and the support rods 67 and the side plates 4 are connected through bearings.

[0072] The working process and principle of this embodiment are:

[0073] When the conveying device for in-situ mixing of the solid waste improved foundation is driven by an external traction vehicle, the pressing wheel 66 rolls and compacts the mixture of the solid waste and the soil, and the compaction of the mixture of the solid waste and the soil is achieved by relying on the weight of the pressing wheel 66.

[0074] Embodiment seven:

[0075] like Figure 4 As shown, this embodiment discloses a conveying device for in-situ mixing of solid waste improved foundation, and its structure is substantially the same as that of the sixth embodiment, except that a coaxial annular plate 61 is rotatably mounted on the end of the pressure wheel 66 of this embodiment, and a coaxial annular fixing frame 64 is fixedly mounted on the end of the pressure wheel 66, and a plurality of insertion rods 65 are slidably mounted on the annular fixing frame 64 at equal angles around the central axis of the pressure wheel 66, and the insertion rods 65 move radially along the pressure wheel 66, and the side surface of the insertion rod 65 is connected to one end of the connecting rod 63 by a bearing or a rotating pin, and the other end of the connecting rod 63 is connected to the side surface of the annular plate 61 by a bearing or a rotating pin, and a positioning bolt 62 is mounted on the annular plate 61.

[0076] When the annular plate 61 is rotated, the annular plate 61 drives the insertion rod 65 to extend or retract the end surface of the pressure wheel 66 through the connecting rod 63 .

[0077] The working process and principle of this embodiment are:

[0078] Before the compaction operation of the compaction assembly 6, the staff rotates the annular plate 61, and the annular plate 61 drives the insertion rod 65 to extend out of the end face of the pressing wheel 66 through the connecting rod 63. Then the staff rotates the bolt 62 so that the bolt 62 presses against the end face of the pressing wheel 66, so that the annular plate 61 cannot rotate. During the rotation of the pressing wheel 66, the insertion rod 65 is inserted into the solid waste and soil mixture to avoid the solid waste and soil mixture from shifting during the rotation of the pressing wheel 66, so that the thickness of the compacted solid waste and soil mixture is uniform.

[0079] After the compaction operation of the compaction assembly 6, the staff rotates the bolt 62 to make the bolt 62 and the end face of the pressure wheel 66 disengage from contact, and the staff rotates the annular plate 61, and the annular plate 61 drives the insertion rod 65 to retract the end face of the pressure wheel 66 through the connecting rod 63. Then the staff rotates the bolt 62 to make the bolt 62 press against the end face of the pressure wheel 66, so as to facilitate the rotation of the pressure wheel 66 on the vehicle driving surface and prevent the insertion rod 65 from damaging the vehicle driving surface.
