[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] like Figures 1 to 7 As shown, the present invention provides an inclined shaft concrete conveying device, including a guide trough 1, a shell 2 is arranged at intervals between the guide trough 1, and the number of shells 2 is set according to the concrete conveying distance and slope. One side of the shell 2 is fixedly connected to the driving motor, and the main shaft of the driving motor extends into the shell 2 and is fixedly connected to at least two fan-shaped box bodies 3. Preferably, the number of box bodies 3 is greater than or equal to six, which plays a buffering role while reducing the impact on the concrete conveying efficiency. For the sake of simplicity, the present invention takes two box bodies 3 as an example. Through grooves 4 are respectively provided on both sides of the shell 2 near the guide trough 1. The through grooves 4 are corresponding to the entrance of the outer arc surface of the box body 3, and an arc plate 7 is fixedly connected between the two box bodies 3. , the curved plate 7 is slidably connected to the inner wall of the shell 2, the box body 3 leaves the through groove 4, the curved plate 7 temporarily closes the through groove 4, the concrete temporarily gathers on the outside of the through groove 4, which plays a buffering role, and the box body 3 receives the concrete that slides down the upstream guide trough 1 and rotates into the shell 2. The entrance of the box body 3 is temporarily closed by the inner wall of the shell 2. When the box body 3 rotates to the through groove 4 on the downstream side of the shell 2 relative to the guide trough 1, it is discharged from the through groove 4 to the subsequent guide trough 1, realizing intermittent transportation and slowing down the influence of continuous acceleration of gravity on long-distance concrete. A cooling water bag 5 is set on the bottom side of the box body 3 in the rotation direction and is rotatably connected to the gravity pressure plate 6, which plays a cooling role in time during long-distance transportation;

[0027] The gravity pressure plate 6 plays a role of expanding the cooling water bag 5 when it is located below the box body 3, and plays a role of compressing the cooling water bag 5 when it is located above the box body 3;

[0028] The housing 2 is provided with a water circulation device, which collects the discharged water from one cooling water bag 5 and supplies water to the other cooling water bag 5 .

[0029] For long-distance inclined shaft tunnels, one of the box bodies 3 receives the concrete sliding down from the upstream material guide trough 1 and rotates, and the entrance of the box body 3 is temporarily closed by the inner wall of the shell 2. When the box body 3 rotates to the through groove 4 on the downstream side of the shell 2 relative to the material guide trough 1, the concrete is discharged from the through groove 4 to the subsequent material guide trough 1, slowing down the sliding speed of the long-distance concrete and cooling the concrete. At the same time, the box body 3 can have a flipping effect, that is, the bottom plate of the box body 3 rotates clockwise when receiving the upstream material guide trough 1, and when the box body 3 filled with concrete rotates to the through groove 4 on the downstream side of the shell 2 relative to the material guide trough 1, the bottom plate of the box body 3 rotates clockwise at the top, which is convenient for intercepting the falling concrete on the one hand, and on the other hand, it plays a role in turning over the concrete. The intermittent conveying cools the concrete, slows down the separation of concrete sand and gravel (the sliding speed of large aggregate is fast), and prevents large aggregate from sinking to the bottom of the concrete mortar.

[0030] Example 2

[0031] like Figures 1 to 7 The top of the support 32 is provided with a plurality of support members 321, 322 and 323, and the support 322 is provided with a plurality of support members 321. The support 322 is provided with a plurality of support members 321 and 323, and the support 322 is provided with a plurality of support members 321.

[0032] Example 3

[0033] like Figures 1 to 7 As shown, the water circulation device has a water suction pipe 81 and a water inlet pipe 82, the water inlet pipe 82 is located below the through slot 4 on the upper side of the shell 2, and the water suction pipe 81 is located below the through slot 4 on the lower side of the shell 2. A water pump 83 is provided on the water inlet pipe 82. A radiator 84 is fixedly connected between the water suction pipe 81 and the water inlet pipe 82. The radiator 84 adopts a conventional structure and is not described in detail here.

[0034] A water supply groove 85 and a drainage groove 86 are provided on the inner wall of the shell 2. The upper ends of the water supply groove 85 and the drainage groove 86 are respectively provided with air leakage holes for balancing the air pressure in the chamber and facilitating the extraction of cooling water. A water suction pipe 81 is provided at the bottom of the drainage groove 86. Two sealing rings 87 are provided on the outer circle of the box body 3 and the arc-shaped plate 7. The water supply groove 85 and the drainage groove 86 are located between the two sealing rings 87, limiting the water absorption and drainage between the two sealing rings 87, playing a role of waterproof sealing. A circular tube 9 is provided on the box body 3 between the two sealing rings 87. The circular tube 9 is connected to the cooling water bag 5. The circular tube 9 only acts as a connecting valve when connected to the water supply groove 85 and the drainage groove 86, and acts as a closing valve for the cooling water bag 5 when in other positions.

[0035] Furthermore, the water supply trough 85 and the drainage trough 86 are respectively provided with arc-shaped protrusions 91, which are provided correspondingly to the circular tube 9. The end of the circular tube 9 away from the arc-shaped protrusion 91 is in a closed structure, and the end surface of the circular tube 9 contacts the arc-shaped protrusion 91 to form an axial displacement.

[0036] One end of the bottom of the rubber support plate 32 is fixedly connected to the horizontal bar 92, and a guide groove 93 is provided on one side of the horizontal bar 92. The guide groove 93 is connected to the inner cavity of the cooling water bag 5. Sliding grooves 94 are provided on both side walls of the mounting groove 31. The two ends of the horizontal bar 92 slide in the sliding groove 94. The horizontal bar 92 is provided with a sliding hole. The circular tube 9 is stepped and slides in the sliding hole. The inner wall of the sliding hole is connected to the guide groove 93. A support spring 95 is fixedly connected between the circular tube 9 and the horizontal bar 92. A waist-shaped groove 96 is provided on the outer wall of the circular tube 9. The waist-shaped groove 96 enters the sliding hole so that the circular tube 9 is connected to the cooling water bag 5 through the guide groove 93.

[0037] In Example 3, after the box body 3 rotates to the through groove 4 on the downstream side of the shell 2 relative to the material guide groove 1, the concrete in the box body 3 is discharged by its own gravity and the squeezing of the gravity pressure plate 6. At the same time, the circular tube 9 rotates to the drainage groove 86, and the gravity pressure plate 6 squeezes the cooling water bag 5 to drain the water. The cooling water squeezed out of the cooling water bag 5 flows into the bottom of the drainage groove 86 and is sucked into the radiator 84 by the suction pipe 81 for heat dissipation, and then pumped into the water supply groove 85. As the box body 3 continues to rotate, the circular tube 9 enters the water supply groove 85, and the circular tube 9 is connected to the cooling water bag 5. The gravity pressure plate 6 expands the cooling water bag 5 to absorb the cooling water, forming a new round of cooling cycle;

[0038] When the cylindrical tube 9 is in contact with the arc-shaped protrusion 91, the cylindrical tube 9 is pushed to slide relative to the horizontal bar 92. The waist-shaped groove 96 on the outer wall of the cylindrical tube 9 enters the sliding hole so that the cylindrical tube 9 is connected with the cooling water bag 5 through the guide groove 93, which plays the role of connecting the cooling water bag 5 and facilitating the drainage of the cooling water bag 5. On the other hand, the cylindrical tube 9 is in contact with the arc-shaped protrusion 91. When the cylindrical tube 9 is connected with the water supply groove 85 and the drainage groove 86, it plays the role of a connecting valve. The cylindrical tube 9 continues to slide to the highest point of the arc of the arc-shaped protrusion 91. At this time, due to the limitation of the step, the cylindrical tube 9 pushes the horizontal bar 92 to overcome the supporting force of the rubber support plate 32 (the rubber support plate 32 itself has elasticity). Through the effect of multiple arc-shaped protrusions 91, water is injected into the cooling water bag 5, while the rubber support plate 32 is vibrated, thereby evenly distributing the concrete, facilitating the concrete to enter between the two baffles 321, dividing the concrete into multiple pieces, and improving the efficiency of contact cooling.

[0039] When the box body 3 rotates to the through groove 4 on the downstream side of the shell 2 relative to the material guide trough 1, the concrete is discharged from the through groove 4 to the subsequent material guide trough 1. The circular tube 9 cooperates with the rubber support plate 32 to move downward through the multiple arc-shaped protrusions 91, and the distance between the two baffles 321 away from the rubber support plate 32 is increased, which facilitates the discharge of concrete.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
