[0014] The above-mentioned prefabricated assembled large-volume concrete chute device is used. Specifically, in the actual setting, since the discharge hopper structure, the collecting hopper structure, the chute main structure, the chute vertical pipe structure and the distribution chute structure are used to form a tool chute and serve as a concrete transportation channel, and then the concrete's own gravity potential energy is used to move the concrete along the tool chute to the pouring position, the concrete pouring method is simple and easy to implement and the concrete flow can be completed only by relying on the gravity potential energy of the concrete. At the same time, the tool chute can also be used for high-rise garbage channels for turnover, which solves the problem of high cost and slow construction speed of pouring large-volume concrete in a small space. Since the chute main structure and the chute vertical pipe structure are both composed of multiple pipe bodies The conical tube body of the plurality of tube unit assemblies is made of plastic material to form the conical tube body. At the same time, the plurality of conical tube bodies are connected to each other by inserting the large end into the small end. The manufacturing method of the plurality of tube unit assemblies is economical and practical, and the series connection method is simple and easy to implement, which is convenient for installation and use, and improves the safety of the chute main pipe structure and the chute vertical pipe structure, meeting the use requirements of concrete pouring. In addition, since the front and rear sides of the conical tube body of each tube unit assembly are respectively provided with the chain and the locking rod, the two conical tube bodies can be connected by clamping the chain of one conical tube body on the locking rod of the other conical tube body and adding the locking ring. The tube units are quickly connected in series, which further improves the combination efficiency between the various tube unit assemblies and facilitates the rapid assembly of the tool-type chute. At the same time, by adjusting the connection position of the chain and the locking rod and increasing or decreasing the tube unit assemblies, the chute main pipe structure and the chute vertical pipe structure can be adapted to the use needs of different floor heights, thereby improving the applicability of the tool-type chute. Since each of the tube unit assemblies is provided with the tube body anti-movement assembly, and then the fixed clamping seat and the movable clamping seat of the tube body anti-movement assembly are clamped on the outside of the tapered tube body, the tapered tube body can be prevented from axial displacement after the arrangement is completed, thereby improving the structure of the chute main pipe structure and the chute vertical pipe. The stability of use after the structure is arranged is achieved. At the same time, the fixed bracket and the movable bracket are fixedly connected together by the connecting screw passing through the connecting hole and then installing the locking nut. The assembly and disassembly method is simple and easy to implement, which not only makes it convenient for the fixed bracket and the movable bracket to be combined together to prevent the tube unit assembly from moving, but also facilitates the subsequent maintenance and replacement operations of the chute main pipe structure and the chute vertical pipe structure after the fixed bracket and the movable bracket are disassembled. Since the telescopic matching tubes are respectively provided on both sides of the hopper structure as the inlet and outlet pipes, the telescopic matching tubes can be extended out of the hopper and retracted into the hopper by means of the threaded engagement of the telescopic matching tube and the matching sleeve.Therefore, when the chute main pipe structure and the chute vertical pipe structure have been arranged in series, it is ensured that the collection bin structure can be smoothly moved to the position between the chute main pipe structure and the chute vertical pipe structure for fixed arrangement by the inward retraction of the telescopic matching pipe, and it is also ensured that when the collection bin structure moves into place, it can be smoothly connected with the chute main pipe structure and the chute vertical pipe structure by the outward extension of the telescopic matching pipe. Since the lower part of the drop bin of the hopper structure is provided with the drop control assembly, the drop control assembly is used to By pulling the gate plate outward and tightening the clamping stud, the bottom of the discharge bin can be opened, and the concrete can be smoothly dropped into the distribution chute structure through the discharge straight pipe, which is convenient for pouring concrete at the side position and prevents the gate plate from moving around in the open state. By pushing the gate plate inward and tightening the clamping stud, the bottom of the discharge bin can be closed, which is convenient for stopping concrete discharge in time when the side pouring is completed and prevents the gate plate from moving around in the closed state. Since the lower part of the collecting hopper structure is also equipped with the buffer inclined pipe and the discharge straight pipe, the buffer The inclined buffering method of the inclined pipe can reduce the impact force when the concrete falls into the discharge straight pipe, thereby ensuring that the concrete will not splash or spill when it continues to fall into the distribution chute structure, which is conducive to ensuring the stable use of the distribution chute structure for lateral concrete pouring. In addition, since the chute formwork of the distribution chute structure is a U-shaped wooden formwork, and the inner periphery of the chute formwork is covered and fixed with the lining made of galvanized iron sheet, it is convenient to obtain and make, and can also avoid affecting the fluidity of the concrete, which is conducive to ensuring the smooth completion of lateral pouring. At the same time, the bottom assembly of the chute formwork is The movable bracket is provided, and the pouring position of the chute formwork can be changed by means of the movable bracket, thereby improving the flexibility of the material distribution chute structure. The discharge bin of the discharge hopper structure can be used as a concrete turnover box, and the grate plate is provided at the top opening of the discharge bin to prevent large aggregates in the concrete from blocking the chute main pipe structure and the chute vertical pipe structure. In addition, the electric stirring mechanism configured in the discharge bin can also continuously stir the concrete in the discharge bin, thereby ensuring the long-term stability of the concrete fluidity.

[0015] The beneficial effects are as follows: 1. The present invention adopts a discharge hopper structure, a collection hopper structure, a chute main pipe structure, a chute vertical pipe structure and a distribution chute structure to form a tool chute as a concrete transportation channel, and then utilizes the concrete's own gravitational potential energy to move the concrete along the tool chute to the pouring position. The concrete pouring method is simple and easy to implement, and the concrete flow can be completed only by relying on the concrete's gravitational potential energy. At the same time, the tool chute can also be used for high-rise garbage channels for turnover, solving the problems of high cost and slow construction speed in pouring large-volume concrete in a narrow space; 2. Both the chute main structure and the chute riser structure are composed of multiple pipe unit assemblies. Each of the multiple pipe unit assemblies is made of a tapered plastic tube. The multiple tapered tubes are connected to each other by inserting the large end into the small end. The production method of the multiple pipe unit assemblies is economical and practical, and the series connection is simple and easy to implement. This not only facilitates installation and use, but also improves the safety of the chute main structure and the chute riser structure, meeting the requirements of concrete pouring. 3. Chains and locking rods are respectively provided on the front and rear sides of the tapered tubes of each tube unit assembly. By clamping the chain of one tapered tube onto the locking rod of another tapered tube and adding a locking ring, the two tapered tubes can be quickly connected in series, further improving the assembly efficiency between the various tube unit assemblies and facilitating the rapid assembly of the tool-type chute. At the same time, by adjusting the clamping position of the chain and the locking rod and adding or removing tube unit assemblies, the chute main pipe structure and chute riser structure can be adapted to different floor height requirements, thereby improving the applicability of the tool-type chute. 4. Each pipe unit assembly is provided with a pipe anti-movement assembly. Then, by clamping the fixed clamp and the movable clamp of the pipe anti-movement assembly on the outside of the tapered pipe body, the tapered pipe body can be prevented from axial displacement after the arrangement is completed, thereby improving the stability of the chute main pipe structure and the chute vertical pipe structure after the arrangement is completed. At the same time, the fixed clamp and the movable clamp are fixedly connected together by passing the connecting screw through the connecting hole and then installing a locking nut. The assembly and disassembly method is simple and easy to implement, which is convenient for combining the fixed clamp and the movable clamp to prevent the pipe unit assembly from moving. It is also convenient for subsequent maintenance and replacement operations of the chute main pipe structure and the chute vertical pipe structure after the fixed clamp and the movable clamp are disassembled. 5. Telescopic matching pipes are respectively provided on both sides of the hopper structure as inlet and outlet pipes. Then, by means of the threaded cooperation between the telescopic matching pipe and the matching sleeve, the telescopic matching pipe can be extended outwards into the hopper and retracted into the hopper. Thus, when the chute main pipe structure and the chute vertical pipe structure have been arranged in series, the hopper structure can be smoothly moved to the position between the chute main pipe structure and the chute vertical pipe structure for fixed arrangement by the retraction of the telescopic matching pipe. At the same time, it can also be ensured that when the hopper structure is moved into place, the telescopic matching pipe can be extended outwards to smoothly complete the plug-in connection with the chute main pipe structure and the chute vertical pipe structure. 6. The lower part of the hopper structure is equipped with a drop control assembly. By pulling out the gate of the drop control assembly and tightening the compression stud, the bottom of the drop hopper can be opened, and the concrete can be smoothly dropped into the distribution chute structure through the discharge straight pipe. This is convenient for pouring concrete at the side and prevents the gate from moving when it is open. By pushing the gate inward and tightening the compression stud, the bottom of the drop hopper can be closed. This is convenient for stopping concrete discharge in time when the side pouring is completed and prevents the gate from moving when it is closed. 7. The lower part of the hopper structure is also equipped with a buffer inclined pipe and a discharge straight pipe. The inclined buffer pipe can reduce the impact force when the concrete falls into the discharge straight pipe, thereby ensuring that the concrete will not splash when it continues to fall into the distribution chute structure, which is conducive to ensuring the stable use of the distribution chute structure for side concrete pouring work; 8. The chute formwork of the material distribution chute structure is a U-shaped wooden formwork. At the same time, the inner periphery of the chute formwork is covered and fixed with a lining made of galvanized iron sheets, which is convenient for production and can avoid affecting the fluidity of concrete, which is conducive to ensuring the smooth completion of side pouring. At the same time, the bottom of the chute formwork is combined with a movable bracket. The casting position of the chute formwork can be changed by means of the movable bracket, which improves the flexibility of the use of the material distribution chute structure. 9. The unloading bin of the unloading hopper structure can be used as a concrete turnover box. At the same time, the top opening of the unloading bin is equipped with a grate plate to prevent large aggregates in the concrete from blocking the chute main pipe structure and the chute vertical pipe structure. In addition, the electric stirring mechanism configured in the unloading bin can also continuously stir the concrete in the unloading bin, thereby ensuring the long-term stability of the concrete fluidity.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below.

The effect of this arrangement is that the concrete can be moved along the tool chute to the pouring position by utilizing the gravity potential energy of the concrete itself. The concrete pouring method is simple and easy to implement and the flow of concrete can be completed only by relying on the gravity potential energy of the concrete. At the same time, the tool chute can also be used for high-rise garbage channels for turnover use, which solves the problem of high cost and slow construction speed of pouring large-volume concrete in a narrow space. It should be noted that the entire tool chute should be set on a preset bracket. The preferred installation scheme of the preset bracket is as follows: the preset bracket is erected with a steel pipe scaffolding, and the preset bracket frame adopts Φ48×2.8 The steel pipe scaffolding is set up in four rows. The vertical pole spacing in the direction of the tool chute is 900mm, the vertical pole spacing along the direction of the tool chute is 1200mm, and the horizontal step spacing is 1500mm. A small cross bar is added on the upper part of the contact part between the tool chute and the small cross bar of the preset frame to fix the tool chute. At the same time, scissor braces must be set up on both sides of the preset frame, and the width of the scissor braces should not be less than 4 spans. In addition, diagonal supports are set up every 4 spans on both sides of the preset frame, and the inclination angle of the diagonal bar to the ground is 1500mm. The angle of the chute is 60°, and horizontal scissors braces and vertical scissors braces are set up every 4 spans. The steel pipe foundation on the inclined surface adopts 25 steel bars embedded in the slope with a depth of 50cm. For the fixation of the chute vertical pipe structure 5, the chute vertical pipe structure 5 is fixed on the steel pipe of each step of the frame by setting up small cross bars of steel pipe scaffolding around the pipe wall. The clamps 401 of the pipe body anti-movement assembly should also be installed in combination on the corresponding scaffolding steel pipe. The connecting rod 402 is fixed by welding and the length is selected and set according to the actual spacing.

[0021] See also Figures 1-8As shown, the number of chute main pipe structures 3 is multiple and all are inclined. Adjacent chute main pipe structures 3 are connected with a collecting hopper structure 2, and the outer end of the chute main pipe structure 3 at the uppermost end is connected with a discharge hopper structure 1. Specifically, the discharge hopper structure 1 includes a discharge bin 103 and a discharge pipe 101.

A grate plate 102 is fixedly connected to the horizontal structure, and the discharge bin 103 is combined with an electric stirring mechanism 104 that can stir the concrete inside. The purpose of this arrangement is that, first of all, the discharge bin 103 can be used as a concrete turnover box, and at the same time, the grate plate 102 can prevent large aggregates in the concrete from blocking the chute main pipe structure 3 and the chute vertical pipe structure 5. In addition, with the help of the electric stirring mechanism 104, the concrete in the discharge bin 103 can also be continuously stirred, thereby ensuring the long-term stability of the fluidity of the concrete.

[0022] See also Figures 1-10As shown, the collecting hopper structure 2 includes an collecting bin 201, a dropping bin 206, a buffer inclined pipe 209 and a dropping straight pipe 207. The collecting bin 201 is consistent with the inclination direction of the chute main pipe structure 3. The top of the collecting bin 201 is open and the bottom is fixedly connected to the dropping bin 206.

The bottom of the dropping bin 206 is vertically fixedly connected to the buffer inclined pipe 209, and the bottom end of the buffer inclined pipe 209 is vertically fixedly connected to the dropping straight pipe 207. Matching holes 202 are provided on both sides of the collecting bin 201, and the matching holes 202 are coaxially interspersed with telescopic matching pipes 203 that can extend outward and retract inward. At the same time, the telescopic matching pipes 203 can be respectively connected to the ends by extending outward. The corresponding chute main structure 3 is plugged in and connected, and the blanking control component 208 includes a mounting box 2082 and a gate 2081. The outer side of the blanking bin 206 is extended and connected with the mounting box 2082, and the mounting box 2082 is inserted with the gate 2081 in a horizontal sliding manner, and the gate 2081 extends into the blanking bin 206 and is horizontally sealed to the blanking bin 206. The bottom surface of the mounting box 2082 is vertically threaded with a clamping stud 2083, and the top of the clamping stud 2083 is pressed tightly on the bottom surface of the gate 2081, and the bottom end of the clamping stud 2083 is coaxially configured with an end head 2084 for easy holding. The reason for this arrangement is that, first, telescopic matching pipes 203 are respectively provided on both sides of the collecting hopper structure 2 as the inlet and outlet pipes, and then with the help of the telescopic matching pipe 2 The threaded cooperation mode of 03 and the matching sleeve 204 can make the telescopic matching tube 203 extend outwards of the collecting bin 201 and retract into the collecting bin 201, so that when the chute main pipe structure 3 and the chute vertical pipe structure 5 have been arranged in series, it can ensure that the collecting bin 201 structure can be smoothly moved to the position between the chute main pipe structure 3 and the chute vertical pipe structure 5 for fixed arrangement by the way of retracting the telescopic matching tube 203, and it can also ensure that when the collecting bin 201 structure is moved into place, it can be smoothly connected with the chute main pipe structure 3 and the chute vertical pipe structure 5 by extending the telescopic matching tube 203 outwards. By pulling out the gate plate 2081 of the blanking control component 208 and tightening the clamping stud 2083, the bottom of the blanking bin 206 can be made to When opened, the concrete can be smoothly dropped into the distribution chute structure 6 through the discharge straight pipe 207, which is convenient for the concrete pouring at the side position and prevents the gate plate 2081 from moving around in the open state. By pushing the gate plate 2081 inward and tightening the compression stud 2083, the bottom of the discharge bin 206 can be closed, which is convenient for stopping the concrete discharge in time when the side pouring is completed and prevents the gate plate 2081 from moving around in the closed state. In addition, by means of the inclined buffer pipe 209 buffering method, the impact force of the concrete when it falls into the discharge straight pipe 207 can be reduced, thereby ensuring that the concrete will not splash or spill when it continues to fall into the distribution chute structure 6, which is conducive to ensuring the stable use of the distribution chute structure 6 for the side concrete pouring work.

[0023] See also Figures 1-10 As shown, the bottom of the collecting hopper structure 2 is connected to a vertical chute riser structure 5, and the bottom of the chute riser structure 5 is provided with a distribution chute structure 6. Specifically, the distribution chute structure 6 includes a chute template 601 and a movable bracket 603.

At the same time, the inclined upper end of the chute template 601 is located below the bottom end of the chute riser structure 5.

Preferably, the chute template 601 is a U-shaped wooden template and the lining 602 is Galvanized iron sheet, the movable bracket 603 is a steel pipe scaffolding. The purpose of this setting is that the chute template 601 of the material distribution chute structure 6 is a U-shaped wooden template, and the inner periphery of the chute template 601 is covered with a lining 602 made of galvanized iron sheet, which is convenient for obtaining and making, and can also avoid affecting the fluidity of concrete, which is conducive to ensuring the smooth completion of side pouring.

The reason is that, first of all, since the multiple tube unit assemblies 7 are all made of plastic tapered tube bodies 701, and the multiple tapered tube bodies 701 are connected to each other by inserting the large end 703 into the small end 702, the manufacturing method of the multiple tube unit assemblies 7 is economical and practical, and the series connection method is simple and easy to implement, which is convenient for installation and use and improves the safety of the chute main pipe structure 3 and the chute vertical pipe structure 5. At the same time, by clamping the chain 707 of one tapered tube body 701 on the locking rod 706 of another tapered tube body 701 and adding a locking ring 705, the two tapered tube bodies 701 can be quickly connected in series, which facilitates the rapid assembly of the tool-type chute. At the same time, by adjusting the clamping position of the chain 707 and the locking rod 706 and adding or removing the tube unit assemblies 7, the chute main pipe structure 3 and the chute vertical pipe structure 5 can also be adapted to the use needs of different floor heights, thereby improving the applicability of the tool-type chute.

The fixed clamping seat 405 and the movable clamping seat 403 are fixed to the middle of the tapered tube 701. 03 The end faces facing each other are vertically extended and fixed with connecting rods 402, and the outer ends of the connecting rods 402 are fixedly connected with the hoop parts 401. The lower wing plates 408 and the upper wing plates 406 are respectively extended and fixed on both sides of the fixed base 405 and the movable base 403. The lower wing plates 408 are each provided with matching holes 202. The upper wing plates 406 are vertically fixed with connecting screws 407, and the connecting screws 407 are coaxially passed through the corresponding matching holes 202 and are equipped with locking nuts 401. 0, is used to fix the fixed bracket 405 and the movable bracket 403 in combination on the outside of the middle section of the conical tube body 701. The advantage of such a setting is that, by means of the fixed bracket 405 and the movable bracket 403 of the tube body anti-movement component being clamped on the outside of the conical tube body 701, the conical tube body 701 can be prevented from axial displacement after being laid out, thereby improving the stability of the chute main pipe structure 3 and the chute vertical pipe structure 5 after being laid out. At the same time, the fixed bracket 405 and the movable bracket 403 are fixedly connected together by passing the connecting screw 407 through the connecting hole 409 and then installing the locking nut 4010. The combined assembly and disassembly method is simple and easy to implement, which is convenient for combining the fixed bracket 405 and the movable bracket 403 together to perform anti-movement protection on the tube body unit assembly 7, and also convenient for subsequent maintenance and replacement operations of the chute main pipe structure 3 and the chute vertical pipe structure 5 after the fixed bracket 405 and the movable bracket 403 are disassembled.

[0026] See also Figures 1-10As shown, the present solution has been optimized as follows. Specifically, the mating hole 202 is an internal threaded hole, and the inner wall of the collecting bin 201 is fixed with a mating sleeve 204 coaxial with the mating hole 202, and the mating sleeve 204 is an internal threaded sleeve. The telescopic mating tube 203 is an external threaded tube, and the telescopic mating tube 203 can be extended and retracted by coaxial threaded mating with the mating hole 202 and the mating sleeve 204. The end of the telescopic mating tube 203 located in the collecting bin 201 is coaxially fixed with a limiting flange 205, and the outer diameter of the limiting flange 205 is larger than the outer diameter of the matching sleeve 204. With this arrangement, it is first convenient to realize the extension and retraction adjustment of the telescopic mating tube 203 by twisting, and the extension length of the telescopic mating sleeve 204 can also be limited by the limiting flange 205. Further optionally, the conical tube body 701 is a plastic conical tube, the locking rod 706 is a stud, and the locking ring 705 is a nut, so that the conical tube body 701 can be easy to manufacture and have a good concrete flow effect, and at the same time, the locking ring 705 and the locking rod 706 can be combined and disassembled by twisting.

[0027] With the above structure, specifically in the actual setting, since the discharge hopper structure 1, the collecting hopper structure 2, the chute main structure 3, the chute vertical pipe structure 5 and the distribution chute structure 6 are used to form a tool chute and serve as a transportation channel for concrete, and then the concrete's own gravity potential energy is used to move the concrete along the tool chute to the pouring position, the concrete pouring method is simple and easy to implement and the concrete flow can be completed only by relying on the gravity potential energy of the concrete. At the same time, the tool chute can also be used for high-rise garbage channels for turnover use, solving the problem of high cost and slow construction speed of pouring large-volume concrete in a small space. Since the chute main structure 3 and the chute vertical pipe structure 5 are composed of multiple pipe unit assemblies 7, the multiple pipe unit assemblies 7 are all made of plastic materials. The conical tube body 701 is made of high quality material, and the multiple conical tube bodies 701 are connected to each other by inserting the large end 703 into the small end 702. The manufacturing method of the multiple tube unit assemblies 7 is economical and practical, and the series connection method is simple and easy to implement, which is convenient for installation and use, and improves the safety of the chute main pipe structure 3 and the chute vertical pipe structure 5, meeting the use requirements of concrete pouring. In addition, since the front and rear sides of the conical tube body 701 of each tube unit assembly 7 are respectively provided with a chain 707 and a locking rod 706, then the chain 707 of one conical tube body 701 is clamped in the locking rod 706 of another conical tube body 701 and a locking ring 705 is added, the two conical tube bodies 701 can be quickly connected in series. The combination efficiency between each tube unit assembly 7 is further improved, and the tool type chute is convenient for quick assembly. At the same time, by adjusting the connection position of the chain 707 and the locking rod 706 and the method of adding or reducing the tube unit assembly 7, the chute main structure 3 and the chute vertical pipe structure 5 can also be adapted to the use needs of different floor heights, thereby improving the applicability of the tool type chute. Since each tube unit assembly 7 is provided with a tube body anti-movement assembly, and then the fixed clamping seat 405 and the movable clamping seat 403 of the tube body anti-movement assembly are clamped on the outside of the tapered tube body 701, the tapered tube body 701 can be prevented from axial displacement after the layout is completed, thereby improving the stability of the chute main structure 3 and the chute vertical pipe structure 5 after the layout is completed. When the fixed card seat 405 and the movable card seat 403 are fixedly connected together by connecting screws 407 through connecting holes 409 and then installing locking nuts 4010, the assembly and disassembly method is simple and easy to implement, which not only facilitates the combination of the fixed card seat 405 and the movable card seat 403 to prevent the pipe unit assembly 7 from moving, but also facilitates the subsequent maintenance and replacement of the chute main pipe structure 3 and the chute vertical pipe structure 5 after the fixed card seat 405 and the movable card seat 403 are disassembled. Since the two sides of the hopper structure 2 are respectively provided with telescopic matching pipes 203 as the inlet and outlet pipes, the telescopic matching pipes 203 can be extended out of the collection bin 201 and retracted into the collection bin 201 by means of threaded cooperation between the telescopic matching pipes 203 and the matching sleeves 204.Therefore, when the chute main pipe structure 3 and the chute vertical pipe structure 5 have been arranged in series, it is ensured that the collection bin 201 structure can be smoothly moved to the position between the chute main pipe structure 3 and the chute vertical pipe structure 5 for fixed arrangement by the way of the telescopic matching tube 203 being retracted inwards, and it is also ensured that when the collection bin 201 structure is moved into place, it can be smoothly connected with the chute main pipe structure 3 and the chute vertical pipe structure 5 by the way of the telescopic matching tube 203 being extended outwards. Since the lower part of the drop bin 206 of the hopper structure 2 is provided with a drop control assembly 208, the gate plate 2081 of the drop control assembly 208 is pulled outwards and By tightening the compression stud 2083, the bottom of the discharge bin 206 can be opened, and the concrete can be smoothly dropped into the distribution chute structure 6 through the discharge straight pipe 207, which is convenient for pouring concrete at the side position and prevents the gate 2081 from moving around in the open state. By pushing the gate 2081 inward and tightening the compression stud 2083, the bottom of the discharge bin 206 can be closed, which is convenient for stopping the concrete discharge in time when the side pouring is completed and prevents the gate 2081 from moving around in the closed state. Since the lower part of the collecting hopper structure 2 is also equipped with a buffer inclined pipe 209 and a discharge straight pipe 207, The inclined buffer pipe 209 can reduce the impact force of concrete when it falls into the discharge straight pipe 207, thereby ensuring that the concrete will not splash or scatter when it continues to fall to the distribution chute structure 6, which is conducive to ensuring the stable use of the distribution chute structure 6 for lateral concrete pouring. Since the chute template 601 of the distribution chute structure 6 is a U-shaped wooden template, and the inner periphery of the chute template 601 is covered with a lining 602 made of galvanized iron sheet, it is convenient to obtain and make, and can also avoid affecting the fluidity of the concrete, which is conducive to ensuring the smooth completion of lateral pouring. At the same time, the bottom assembly of the chute template 601 is fixed. A movable bracket 603 is provided, and the pouring position of the chute template 601 can be changed by the movable bracket 603, thereby improving the flexibility of the distribution chute structure 6. Since the discharge bin 103 of the discharge hopper structure 1 can be used as a concrete turnover box, and the top opening of the discharge bin 103 is equipped with a grate plate 102, it can prevent large aggregates in the concrete from blocking the chute main structure 3 and the chute vertical pipe structure 5. In addition, the electric stirring mechanism 104 configured in the discharge bin 103 can also continuously stir the concrete in the discharge bin 103, thereby ensuring the long-term stability of the concrete fluidity.
