Detailed Implementation

[0021] like Figure 1-4 As shown, an adjustable concrete chute includes a mobile trolley. A first chute body 10, a second chute body 11, and a third chute body 12 are detachably mounted on the top of the mobile trolley. The first chute body 10, the second chute body 11, and the third chute body 12 are detachably connected together by bolts. Specifically, the two ends of the second chute body 11 overlap the first chute body 10 and the third chute body 12 to prevent concrete from falling from the gaps at the joints.

[0022] like Figure 2 As shown, the mobile trolley includes a base plate 1. A height adjustment frame is connected to the top surface of the base plate 1 near both sides. An adjustment seat 13 is movably connected to the top of the height adjustment frame. A connecting seat 14 is connected to the top surface of the adjustment seat 13. Mounting seats 15 are connected to the bottom surfaces of the first chute body 10 and the third chute body 12. The mounting seats 15 are detachably connected to the connecting seats 14 by bolts.

[0023] Specifically, the height adjustment frame includes two fixed tubes 2, which are connected side by side to the top surface of the base plate 1. A connecting beam 16 connects the two fixed tubes 2. A lifting rod 3 is provided on the upper part of the fixed tube 2. The bottom of the lifting rod 3 is inserted into the fixed tube 2 and locked and positioned by a locking bolt 4. A limiting groove 3-1 is opened on the opposite surface of the two lifting rods 3. The end of the locking bolt 4 passes through the mounting hole on the lifting rod 3 and is pressed against the limiting groove 3-1. A crossbeam 5 is connected to the top of the two lifting rods 3. A drive mechanism for driving the crossbeam 5 to rise and fall is provided below the crossbeam 5. The adjustment seat 13 is hinged to the top of the lifting rod 3.

[0024] The drive mechanism includes a rotating seat 7, which is rotatably mounted in a through hole at the middle position of the connecting beam 16 via a bearing. A screw 6 is threadedly connected to the center of the rotating seat 7. The top end of the screw 6 is connected to the crossbeam 5, and the bottom end of the screw 6 extends to the bottom of the connecting beam 16. A handwheel is installed on the top of the rotating seat 7.

[0025] In use, rotating the handwheel causes the rotating seat 7 to rotate, which in turn causes the screw 6 to rise. The screw 6 then pushes the crossbeam 5 to rise, thereby causing the lifting rod 3 to rise, thus increasing the overall height of the height adjustment frame. By adjusting the height of the two height adjustment frames, the tilt angles of the first chute body 10, the second chute body 11, and the third chute body 12 can be adjusted.

[0026] like Figure 3 As shown, the adjusting seat 13 has an arc-shaped adjusting groove, and a fixing bolt is installed in the adjusting groove. The fixing bolt passes through the adjusting groove and is threadedly connected to the lifting rod 3, thereby locking the position of the adjusting seat 13.

[0027] The base plate 1 has casters 8 installed at the four corners of its bottom surface, and the casters 8 are equipped with brakes. In addition, the base plate 1 has adjustable feet 9 installed on the bottom surface and on one side of the casters 8. When the road surface is uneven, the height of the adjustable feet 9 can be changed to keep the moving trolley stable.

[0028] During use, to prevent the mobile trolley from tipping over, sandbags can be added to the top surface of the base plate 1 as a counterweight.

[0029] The working process of this utility model is as follows:

[0030] First, the first chute body 10, the second chute body 11 and the third chute body 12 are connected together by bolts to form an integral chute;

[0031] Then, the mounting base 15 is bolted to the connecting base 14, thereby installing the entire chute onto the mobile trolley;

[0032] Next, rotate the handwheel to rotate the rotating seat 7. The rotation of the rotating seat 7 causes the screw 6 to rise, and the screw 6 pushes the crossbeam 5 to rise, thereby causing the lifting rod 3 to rise, increasing the overall height of the height adjustment frame. Adjust the height of the other height adjustment frame in the same way. Adjust the slope of the chute by adjusting the height of the two height adjustment frames. After the adjustment is completed, tighten the locking bolt 4 so that the end of the locking bolt 4 passes through the mounting hole on the lifting rod 3 and is pressed against the limit groove 3-1 to lock the position of the lifting rod 3. Tighten the fixing bolt. The fixing bolt passes through the adjustment groove and is threaded to the lifting rod 3, thereby locking the position of the adjusting seat 13.

[0033] Next, move the mobile cart to the work position;

[0034] Finally, the concrete from the tanker truck is poured into the chute. One person controls the concrete discharge rate and directs the tanker truck to move forward, while another person works with the workers at the bottom of the pit to control the amount of concrete. Once the concrete bedding and sealing layer have been filled to a sufficient quantity, the remaining concrete in the chute is cleaned up and the truck is moved to the next pouring point. This process ensures that the bedding and sealing layer construction is completed at a uniform speed. The process is flexible, does not spill out, is easy to operate, reduces waste, and is highly efficient.

[0035] When not in use, remove the mounting base 15 from the connecting base 14 to separate the entire chute from the moving trolley. Disassemble the first chute body 10, the second chute body 11, and the third chute body 12 into three sections and keep them for later use. The moving trolley can be used normally for other purposes, such as transporting prefabricated well chamber steel bars.

[0036] The aforementioned adjustable concrete chute requires cleaning after construction and can be used as a supporting equipment for foundation pit pouring construction to meet long-term use needs.

[0037] In practical work, commonly available waste templates, timber, steel pipes, and reinforcing bars can be used for modification. The waste templates can be assembled into three "U"-shaped sections: the first section is 1×0.5×0.3mm, the second is 1.5×0.52×0.31mm, and the third is 1.5×0.54×0.32mm, reinforced with timber. Symmetrical holes are made on the sides of the template, three on each side, spaced 25cm apart, to facilitate connection between two "U"-shaped template sections. During use, the trolley is connected to the "U"-shaped template (the number of chute sections used depends on the site conditions; if too many chute sections are added, a counterweight needs to be added to the end of the trolley). The trolley is adjusted to a downward-sloping discharge chute. Ready-mixed concrete is poured into the "U"-shaped template chute, flowing into the trench under its own weight. One person operates and controls the direction and position of the chute, while another person directs the concrete truck and controls the discharge chute regulating gate, slowly releasing the concrete into the template, thus uniformly pouring the concrete foundation layer.
