The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 3 As shown, the present invention provides a fertilizer tank backfilling device, comprising: a support frame 1, a receiving hopper 2, and a guide tube.

[0030] The support frame 1 is arranged in the horizontal direction. The support frame is used to set up the receiving hopper.

[0031] Specifically, the support frame 1 has a first side and a second side facing each other. Multiple wall-mounting rods 17 are mounted on the first side of the support frame 1 in a scalable manner. These rods 17 are used to mount the top of one side wall of the fertilizer trough. A cantilever rod 12 is connected to the other side of the support frame 1. The cantilever rod 12 is used to rest on the top of the other side wall of the fertilizer trough. A wall-mounting rod 13 is adjustable and mounted on the cantilever rod 12. The wall-mounting rod 13 is used to press against the other side wall.

[0032] The receiving hopper 2 is mounted on the supporting frame 1. The discharge port of the receiving hopper 2 is aligned with the notch of the fertilizer tank.

[0033] The guide tube includes a flexible fabric tube 3 and multiple inner support collars 31. The flexible fabric tube is vertically positioned within the manure tank. The inner support collars 31 are supported on the inner wall of the flexible fabric tube 3. The inner support collars 31 are spaced apart along the length of the flexible fabric tube 3. The multiple inner support collars 31 are mounted on the flexible fabric tube, forming a vertical flexible sleeve.

[0034] The upper end of the flexible cloth tube 3 is connected to the discharge port. The lower end of the flexible cloth tube 3 extends to the bottom of the fertilizer tank.

[0035] As a preferred embodiment, the inner support ring 31 of the lower end of the flexible cloth tube 3 is connected to opposite sides of the inner support ring 31. During the backfilling process of the fertilizer trough, the flexible cloth tube is gradually pulled upward by the lifting rope, so that the lower end of the flexible cloth tube gradually rises, thereby achieving layered backfilling of the soil in the fertilizer trough.

[0036] As a preferred embodiment, the support frame 1 includes at least two trusses 11 and a connecting beam 14 .

[0037] At least two trusses 11 are arranged in the same direction. Specifically, the trusses 11 include two chord members 111 and a web member 112 arranged opposite to each other. The web member 112 is connected between the two chord members 111. There are multiple web members 112. The multiple web members are spaced apart along the length of the chord members.

[0038] At least two ends of the two trusses 11 are respectively connected to connecting beams 14 .

[0039] See Figure 1 There are four trusses, with walkway panels placed on the two middle trusses. The two middle trusses form a material dropout opening with the remaining two trusses. The feeding port of the receiving hopper is connected to the material dropout opening. There are two receiving hoppers, each located at opposite ends of the support frame.

[0040] See Figure 3 The wall hanging rod 17 is attached to one side wall of the fertilizer tank. The upper end of the wall hanging rod 17 is connected to an end rod 18. The top of one side wall of the fertilizer tank is supported by the end rod 18.

[0041] The wall-mounted rod 17 is disposed between one end of the two chord rods 111. The wall-mounted rod 17 is provided with a plurality of first locking holes. One end of the chord rod 111 is provided with a second locking hole aligned with one of the first locking holes. The first locking rod 15 is detachably inserted into the first and second locking holes.

[0042] See Figure 2 The other end of the chord 111 extends to form a cantilever rod 12. The upper end of the wall-abutting rod 13 is disposed between the two cantilever rods 12. The cantilever rod 12 defines a plurality of third locking holes. The wall-abutting rod 13 defines a fourth locking hole aligned with one of the third locking holes. A second locking rod 16 is detachably inserted into the third and fourth locking holes.

[0043] As a preferred embodiment, the diameters of the plurality of inner support collars 31 gradually decrease from bottom to top. The plurality of inner support collars 31 are arranged at equal intervals. The spacing between two adjacent inner support collars 31 is adapted to the layer height of the layered backfill of the fertilizer tank.

[0044] When the flexible cloth tube of the guide tube is lifted, the lower end of the flexible cloth tube is folded upward, thereby adjusting the length of the flexible cloth tube. Since the distance between the two inner support rings is adapted to the layer height of the fertilizer tank, the fertilizer tank can be backfilled layer by layer by lifting one layer height each time.

[0045] The present invention provides a construction method of a fertilizer tank backfilling device, comprising the following steps:

[0046] S1: Based on the height difference between the tops of the two side walls of the fertilizer trough, the multiple wall-hanging rods 17 on the first side of the lifting support frame 1 are raised and lowered so that the multiple wall-hanging rods 17 are hung on the top of one side wall of the fertilizer trough and the supporting frame 1 is arranged in the horizontal direction, and the cantilever rods 12 on the second side of the supporting frame 1 are placed on the top of the other side wall of the fertilizer trough.

[0047] Based on the distance between the two side walls of the fertilizer trough and the height difference between the tops of the two side walls of the fertilizer trough, the first locking rod and the second locking rod are adjusted so that the distance between the end rod and the supporting frame is adapted to the height difference, and the distance between the wall-hanging rod and the wall-aft rod is adapted to the distance.

[0048] After adjusting the height of the end rod and the position of the wall rod, the fertilizer trough backfill device is erected at the backfill construction point of the fertilizer trough by a crane.

[0049] S2: Based on the distance between the two side walls of the fertilizer trough, adjust the position of the wall-abutting rod 13 on the cantilever rod 12 of the support frame 1 so that the wall-abutting rod 13 is pressed against the other side wall, thereby aligning the discharge port of the receiving hopper 2 with the notch of the fertilizer trough and the lower end of the flexible cloth tube 3 extending to the bottom of the fertilizer trough.

[0050] S3: dump the backfill soil into the receiving hopper 2, and the backfill soil is backfilled into the fertilizer tank in layers through the flexible cloth tube 3.

[0051] When backfilling on site, the backfill volume can be increased through two receiving hoppers. The backfilling method can be to set up fertilizer trough backfilling devices at both ends of the fertilizer trough to backfill simultaneously, thereby increasing the backfilling efficiency.

[0052] After backfilling at one backfill construction point, the fertilizer trough backfilling device is adjusted based on the distance and height difference of the next backfilling point and hoisted to the next backfilling point to backfill the earth.

[0053] The fertilizer trough backfilling device of the present invention is adapted to different widths of the fertilizer trough and different height differences of the top of the side wall by adjusting the height of the wall hanging rod and the position of the wall-abutting rod. Therefore, the fertilizer trough backfilling device of the present invention can be used for backfilling the entire section of the fertilizer trough at the construction site, realizing rapid layered backfilling of the fertilizer trough and improving the engineering construction efficiency of the underground structure.
