Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] The embodiment of the present application provides a method for solving the technical problem in the prior art that the bottom of the material conveying equipment is prone to material accumulation and causes the rotating main shaft to break.

[0034] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0035] like Figure 1 、 Figure 2 As shown, the present application provides a conveying device for contaminated soil remediation, comprising: a lower hopper 100, a belt conveyor assembly 1 and a pneumatic pusher assembly 10 arranged in sequence from top to bottom;

[0036] like Figure 1 、 Figure 2 、 Figure 4 As shown, the pneumatic pushing assembly 10 includes:

[0037] A material pushing trough 110, wherein a material pushing assembly is provided inside the material pushing trough 110, and a material discharge port 111 is provided at one end of the material pushing trough 110;

[0038] A pushing cylinder 11 is hingedly arranged at one end of the pushing trough 110 away from the discharge port 111, and an output end of the pushing cylinder 11 is fixedly connected to the pushing assembly;

[0039] The arm lifting cylinder 12 is hingedly arranged on the side of the pushing trough 110. The output end of the arm lifting cylinder 12 is connected to the hanging shaft transmission connecting rod 14 through the arm lifting transmission mechanism. The hanging shaft transmission connecting rod 14 is hinged to the pushing assembly through the first connecting rod 141.

[0040] Preferably, the push plate 18 is provided with two cylinder assemblies, and the cylinder located at the end of the belt conveyor is responsible for the horizontal reciprocating pushing function; the arm lifting cylinder 12 arranged on the side of the belt conveyor unit is responsible for lifting the pushing assembly through the arm lifting transmission mechanism after the material is delivered to the discharge port 111, so that the pushing assembly is suspended in the air, and then, driven by the pushing cylinder 11, returns to the starting position of the pushing assembly, reducing the friction between the pushing assembly and the pushing trough 110, and preventing the pushing assembly from pushing the material back during the recovery movement.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] Preferably, there are at least two suspension shaft transmission links 14, and the arm lifting transmission mechanism includes a second link 142 and a third link 13. The second link 142 is fixedly arranged at the end of the suspension shaft transmission link 14, and the third link 13 is arranged below the suspension shaft transmission link 14. The second link 142 is rotatably connected to the third link 13, and the output shaft of the arm lifting cylinder 12 is rotatably connected to the third link 13.

[0043] The power is transmitted to the entire pusher assembly through the suspension shaft transmission link 14, and the arm lifting cylinder 12 drives the suspension shaft transmission link 14 to rotate through the second link 142 and the third link 13, thereby lifting the entire pusher assembly. The operation is simple and convenient, and prevents the pusher assembly from bringing materials back when moving back.

[0044] Further, such as Figure 5 As shown, the pusher assembly includes a push plate cross bar 16, a push plate vertical bar 17 and a push plate 18. The push plate cross bar 16 is a plurality of parallel fixed arrangements on the push plate vertical bar 17. The push plate 18 is fixedly arranged on the push plate cross bar 16. The output end of the push cylinder 11 is fixedly connected to the push plate vertical bar 17. In this embodiment, the push plate cross bar 16 is a push plate angle steel, the push plate vertical bar 17 is a push plate square tube, and the push plate 18 is a polyurethane plate, which is customized according to the size of the bracket 120. The use of the polyurethane plate not only reduces the abnormal noise during the operation of the equipment, but also achieves the purpose of reducing the operating load of the push cylinder 11 when conveying materials normally.

[0045] It should be noted that the spacing between the polyurethane push plates 18 should be smaller than the effective stroke of the push cylinder 11. Different numbers of push plates 18 can be set according to the length of the push plates. There is no specific limit on the number of push plates 18 in the present invention.

[0046] The lower bin 100 is fixedly arranged above the belt conveyor assembly 1 through a bracket 120 , and the pushing chute 110 is fixedly connected to the bracket 120 .

[0047] like Figure 2 As shown, an adjustment port 112 is set at the front end of the discharge port 111 of the discharge bin 100, and slots 113 are set on both sides of the adjustment port 112. The adjustment plug is inserted into the slot 113 to block the adjustment port 112. The flow of the material is controlled by adjusting the position of the adjustment plug on the adjustment port 112.

[0048] Specifically, the belt conveyor assembly 1 includes a driving pulley 3, a driven pulley 2, a belt supporting pulley group 5 and a belt driving mechanism 6. The driving pulley 3 and the driven pulley 2 are installed at both ends of the pushing trough 110 through bearing seats. The belt supporting pulley group 5 is arranged between the driving pulley 3 and the driven pulley 2. A conveying belt 4 is provided on the belt supporting pulley group 5, the driving pulley 3 and the driven pulley 2.

[0049] Preferably, if Figure 1-Figure 3 As shown, the driving pulley 3 and the driven pulley 2 on both sides of the belt are both grille pulleys, the belt support pulley group 5 is a through-type straight pulley group, and the grille pulley is composed of customized ribs 31, customized plates 32 and customized main shafts 33. The customized main shaft 33 is located in the center, and the customized plates 32 are vertically connected to the customized main shaft 33. The customized plates 32 and the customized main shaft 33 are coaxially arranged, and the customized plates 32 are connected by customized ribs 31 to avoid the situation where the material sticks to the wheel and causes the belt to deviate. The customized plates 32 on both sides of the customized main shaft 33 are provided with cleaning ports 34 for cleaning dirt in the driving pulley 3 and the driven pulley 2.

[0050] The belt drive mechanism 6 includes a variable frequency motor, a reducer and a roller chain. The output ends of the variable frequency motor and the reducer are connected to the roller chain and the driving pulley 3.

[0051] The belt drive machine drives the driving pulley 3 to rotate, and the belt supporting pulley assembly 5 lifts the belt so that the belt can be tightened. The belt transports the material to the discharge port 111, thereby improving the conveying efficiency.

[0052] In some embodiments, as Figure 1 As shown, the belt conveyor assembly 1 further includes a sealing cover 7 , which covers the conveying belt 4 , and an air suction port 8 is provided at one end of the sealing cover 7 close to the discharge port 111 .

[0053] The sealing cover 7 around the belt is a closed shell, and a dust removal suction port 8 is set at the discharge end. When the belt is running, the dust inside the belt conveyor can be sucked away through the suction port 8, maintaining the sealing cover 7 under a slightly positive pressure condition or a slightly negative pressure condition, and the system can feed smoothly with zero interference to meet the process requirements required for production; inspection ports can be set on both sides of the sealing cover 7.

[0054] In some embodiments, as Figure 1 、 Figure 6 As shown, a discharger 19 is connected below the discharge port 111 , and two sets of impellers 20 rotating in opposite directions are provided in the chamber of the discharger 19 .

[0055] Preferably, the two rotating impellers 20 of the discharger 19 rotate in opposite directions, and the fallen materials are discharged into the bottom conveying device under the rotation of the impellers 20. Both sides of the chamber are set in arcs. Under the premise of ensuring that the materials can be conveyed normally, the air locking effect of the system is also well guaranteed, which is convenient for solving the fault of material blocking or jamming.

[0056] Furthermore, it also includes a timing transmission gear 21 arranged at the end of the dual-axis discharger 19, which can not only realize the transmission of torque, but also realize the condition that the two rotating impellers 20 always run synchronously, ensuring that there is no mutual collision or tooth jamming between the two impellers 20 in the chamber. Through the staggered installation of the timing gears, the interaction, superposition and staggered peaks of the two impellers 20 are realized, which not only realizes the wind locking effect, but also discharges the materials with higher moisture content and higher viscosity from the chamber through the alternating rotation of the blades, realizing fast, uniform and continuous unloading, and achieving the purpose of the two impellers 20 cleaning the adhered materials from each other and making the materials discharged smoothly.

[0057] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0058] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
