[0025] like Figures 1 to 8 As shown, the present invention provides a soil conveying device for deep foundation pit construction, including several conveying modules 1 and at least two power drive devices; the conveying module 1 adopts a C-shaped box structure, so that multiple conveying modules 1 are hooked and matched, that is, the openings of two upper and lower adjacent conveying modules 1 are opposite to each other, and the lower conveying module 1 extends into the opening of the upper conveying module 1 and is hooked and matched with its lower part. As shown in 1, the number of conveying modules 1 can be adjusted according to the actual depth of the deep foundation pit, thereby adjusting the height of the entire device, and the side close to the side wall of the deep foundation pit is installed and fixed by an installation structure.

[0026] The conveying modules 1 are all provided with soil conveying devices, and the soil conveying devices of the two adjacent conveying modules 1 can be driven by the transmission structure so that the soil conveying devices of the two adjacent conveying modules 1 can work and soil can be transferred between the two adjacent soil conveying devices; the top and bottom surfaces of each conveying module 1 are provided with a mounting seat 19 for detachably installing a power drive device, so that the entire device is driven by the two power drive devices at the top and bottom, and the transmission structure is used to drive the soil between the two adjacent conveying modules 1, so that the soil conveying devices inside all conveying modules 1 can work and transfer the soil at the bottom of the deep foundation pit from bottom to top. At the same time, the two adjacent conveying modules 1 are fixed by a fixed locking structure, so that the entire device is more stable when in use.

[0027] One embodiment of the soil conveying device is that a C-shaped cavity 2 is provided inside the conveying module 1, and the cavity 2 includes a first curved portion 3 at the top, a vertical portion 4 in the middle, and a second curved portion 5 at the bottom. A first rotating shaft 6 along the front-to-back direction is provided near the end of the first curved portion 3, and the front and rear ends of the first rotating shaft 6 are respectively rotatably connected to the corresponding inner wall of the cavity 2, and a first chain roller 8 is fixedly installed on the outer periphery of the first rotating shaft 6; a second rotating shaft 7 along the front and rear directions is provided near the end of the second curved portion 5, and the front and rear ends of the second rotating shaft 7 are respectively rotatably connected to the corresponding positions of the cavity 2, and a second chain roller 9 is fixedly installed on the outer periphery of the second rotating shaft 7, and the first chain roller 8 and the second chain roller 9 located in the same cavity 2 are connected by a conveying chain plate 10, and C-shaped slide grooves 11 are provided on the inner walls on both sides of the front and rear of the cavity 2, and the front and rear ends of the conveying chain plate 10 extend into the slide grooves 11 on the corresponding sides and slide with them, such as Figure 2 As shown in the figure, the conveying module 1 at the uppermost end and the conveying module 1 at the lowermost end are driven to rotate by the power driving module, and the adjacent conveying modules 1 are connected by the transmission structure, so that all the conveying chain plates 10 are moved, and the conveying chain plates 10 on one side of the opening of the corresponding conveying module 1 in the cavity 2 are moved from bottom to top, so that the overall conveying from top to bottom can be realized.

[0028] The transmission chain plates 10 each include a plurality of first chain plates, which are hingedly connected head to tail to form a closed loop, and a plurality of arc-shaped transmission plates 14 are fixedly installed on the outer side of the first chain plates, and the front and rear sides of the transmission plates 14 are respectively matched with the inner wall gaps of the corresponding sides of the cavity 2, such as Figure 2 As shown in FIG. 1 , the concave surface of the conveying plate 14 near the opening of the conveying module 1 faces upward, so that the concave surface of the conveying plate 14 located directly below the second through hole 13 faces the corresponding vertical portion 4. Figure 2 As shown in FIG. 1 , a vertical first through hole 12 is formed at the end of the first curved portion 3. Figure 4As shown in , the curved portion of the second curved portion 5 is provided with a vertical second through hole 13, and when the transmission module 1 is hooked and matched, the first through hole 12 and the second through hole 13 are connected and communicated; Figure 5 As shown in the figure, when the soil is transported from bottom to top, the soil is poured into the cavity 2 from the second through hole 13 corresponding to the lowermost conveying module 1, and because the front and rear ends of the conveying plate 14 are in contact with the corresponding sides of the cavity 2, the front and rear ends of the first chain plate are inserted into the slide groove 11, so that the soil entering the cavity 2 falls on the conveying chain plate 10 on the upper side of the second curved portion 5, and the soil falls between the two adjacent conveying plates 14 located below the second through hole 13. In this way, as the conveying chain plate 10 moves, the soil moves to the vertical portion in the cavity 2 and falls into the concave surface of the conveying plate 14 below it under the action of gravity. In this way, the soil can be conveyed from bottom to top in the corresponding conveying module 1 through the conveying plate 14.

[0029] The first curved portion 3 is provided with an upwardly inclined guide plate 15, the upper ends of which are all facing the upper part of the vertical portion 4 and the upper ends of which are flush with the inner walls of the corresponding sides of the vertical portion 4; when the conveying plate 14 conveys the soil to the uppermost end of the vertical portion 4, the conveying chain plate 10 moves toward the side of the first curved portion 3, and in this process, the side of the conveying plate 14 connected to the conveying plate 10 gradually turns upward, so that the soil in the conveying plate 14 gradually falls downward on the corresponding guide plate 15 under the action of gravity, and the soil moves downward along the guide plate 15 to the end of the first curved portion 3, and successively passes through the first through hole 12 and the second through hole 13 into the interior of the conveying module 1 on the upper side, thereby repeating the above-mentioned conveying steps inside the conveying module 1 on the upper side, so that the soil is connected to the conveying module 1 from bottom to top for docking and conveying, until it is conveyed to the uppermost conveying module 1, and then output through the first through hole 12 of the uppermost conveying module 1, so that the soil in the deep foundation pit can be conveyed.

[0030] One implementation of the transmission structure is that the front end of the first rotating shaft 6 passes through the corresponding cavity 2 and is rotatably connected thereto, the front end of the second rotating shaft 7 passes through the corresponding side of the cavity 2 and is rotatably connected thereto, the first pulley 17 is fixedly installed on the outer periphery of the front end of the first rotating shaft 6 and the front end of the second rotating shaft 7, a vertical adjustment groove 23 is provided on the outer side of the transmission module 1 corresponding to the first rotating shaft 6 close to the vertical part, and a first slider 24 is provided in the adjustment groove 23 to slide with and lock therewith, and a first tensioning wheel 25 is rotatably installed on the outer side of the first slider 24, so that the height of the first tensioning wheel 25 can be adjusted by vertically moving the first slider 24 along the corresponding adjustment groove 23; the second tensioning wheel 26 is rotatably installed on the outer side of the transmission module 1 corresponding to the first rotating shaft 6 away from the vertical part, and the two first pulleys 17 corresponding to one side of the hooked cooperation of two adjacent transmission modules 1 and the corresponding first tensioning wheel 25 and the second tensioning wheel 26 are connected by a first belt 18, such as Figure 7 As shown in , the first pulley 17 located on the lower side (i.e., the first pulley 17 on the outer side of the first rotating shaft 6 in the hooking part of the two adjacent conveying modules 1) is located on the inner side of the first belt 18, and the first pulley 17 located on the upper side (i.e., the first pulley 17 on the outer side of the second rotating shaft 7 in the hooking part of the two adjacent conveying modules 1) is located on the outer side of the first belt 18, so that the first belt 18 is connected between the soil conveying structures between the two adjacent conveying modules 1, and the tightness of the first belt 18 can be adjusted by vertical movement of the first slider 24, which is convenient for the installation and disassembly of the first belt 18. At the same time, such a connection method can not only enable transmission between the two adjacent conveying modules 1, but also enable the conveying chain plates 10 in the two adjacent conveying modules 1 to move from bottom to top near the opening of the conveying module 1, as shown in FIG. Figure 7 As shown by the middle arrow, this ensures that the entire device can transfer the soil from bottom to top; of course, the transmission structure can be implemented by other structures with the same function.

[0031] In one embodiment of the power drive device, each power drive device includes a motor 20, the motor 20 is detachably mounted on the mounting seat 19, and the output shaft of the motor 20 is fixedly mounted with a second pulley 21, such as Figure 8 As shown in , the second pulley 21 and the first pulley 17 can be connected by a second belt 22 with adjustable length. When in use, the mounting seat 19 at the upper end of the uppermost conveying module 1 is installed with the motor 20, and the mounting seat 19 at the lower end of the conveying module 1 is installed with the motor 20, as shown in Figure 1 As shown in , any transmission module 1 can be detachably installed with a power drive device for use when it is located at the uppermost end or the lowermost end. Of course, the power drive device includes but is not limited to this embodiment.

[0032] In order to further reduce manual participation and improve the construction efficiency of the deep foundation pit, a horizontal first conveying structure can be set below the first through hole 12 corresponding to the conveying module 1 at the uppermost end, and the soil conveyed from bottom to top by this device passes through the first through hole 12 corresponding to the conveying module 1 at the uppermost end and falls on the first conveying structure to be conveyed to the outside of the deep foundation pit; of course, a horizontal second conveying structure can be set above the second through hole 13 corresponding to the conveying module 1 at the lowermost end, so that the soil at the bottom of the deep foundation pit only needs to be placed on the second conveying structure and then conveyed to the second through hole 13 through the second conveying structure.

[0033] Working principle: During the construction of the deep foundation pit, as the construction progress of the deep foundation pit progresses, the depth of the deep foundation pit will gradually deepen. The number of conveying modules 1 is adjusted according to the actual depth of the deep foundation pit. When in use, several conveying modules 1 are distributed up and down, and the openings of the two adjacent conveying modules 1 are opposite to each other. The lower conveying module 1 extends into the opening of the upper conveying module 1 and is hooked with its lower part to cooperate with the side close to the side wall of the deep foundation pit for installation and fixation through the mounting structure; the soil at the bottom of the deep foundation pit is placed on the second conveying structure, and is conveyed to the second through hole 13 through the second conveying structure. The soil that enters the corresponding cavity 2 from the second through hole 13 of the lowest conveying module 1 falls on the soil that enters the cavity 2 and falls on the conveying chain plate 10 on the upper side of the second curved portion 5, and the soil falls between the two adjacent conveying plates 14 below the second through hole 13. In this way, as the conveying chain plate 10 moves, the soil moves to the vertical portion in the cavity 2 and falls on the conveying plate 14 below it under the action of gravity. When the soil is transported to the uppermost portion 4, the conveyor plate 10 moves toward the first curved portion 3, and in the process, the side of the conveyor plate 14 connected to the conveyor plate 10 gradually turns upward, so that the soil in the conveyor plate 14 gradually falls downward on the corresponding guide plate 15 under the action of gravity, and the soil moves downward along the guide plate 15 to the end of the first curved portion 3, and passes through the first through hole 12 and the second through hole 13 in turn to enter the conveyor module 1 on the upper side, so that the above-mentioned conveying steps are repeated inside the conveyor module 1 on the upper side, so that the soil is transported from bottom to top by each conveyor module 1 until it is transported to the uppermost conveyor module 1, and then output through the first through hole 12 of the uppermost conveyor module 1, and the first through hole 12 corresponding to the conveyor module 1 at the uppermost end falls on the first conveying structure to be transported to the outside of the deep foundation pit, thus completing the entire conveying process.

[0034] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
