Description

Technical Field

[0001] This invention belongs to the technical field of building construction, specifically an automatic material control pouring hopper for high-altitude concrete and its pouring method. Background Technology

[0002] Concrete hoppers are key tools in construction engineering for transferring, temporarily storing, and precisely controlling concrete pouring. They are indispensable, especially in space-constrained or high-rise construction. By temporarily storing concrete in complex or restricted construction sites and using a controllable discharge system, they can achieve precise and uniform material distribution, effectively preventing concrete segregation and ensuring pouring quality and structural density.

[0003] Patent document CN113944333A describes a multifunctional concrete pouring hopper for building construction. The discharge trough is opened on the side plate of the hopper. The reinforcing plate is fixedly installed on the front and rear inner side walls of the discharge trough. The material blocking component is screwed on the outer side wall of the hopper and covers the discharge trough. It is sandwiched between the reinforcing plates. The threaded rod is screwed on the lower side of the front side wall of the front reinforcing plate through a bearing. The connecting frame is screwed on the lower end of the material blocking component through a rotating shaft. Its front end extends from the lower side of the front reinforcing plate and is movably sleeved on the threaded rod. The connecting block is fixedly installed on the connecting frame and is screwed on the threaded rod. The support component is fixedly installed on the lower side of the rear reinforcing plate.

[0004] Traditional concrete pouring hoppers generally suffer from problems such as crude unloading control, easy material sticking and clogging, significant operational safety hazards, low automation, and insufficient structural durability. During high-altitude concrete pouring, the manual operation of concrete hoppers relies heavily on gate handles or inserts, making it difficult to precisely control the discharge speed and prone to "material interruption" or "pipe bursting." There is also a risk of concrete splashing during discharge, and close-range operation can easily result in burns. If the concrete inside the hopper clumps, uneven force during opening and closing may cause the gate to suddenly detach, leading to material falling and injuring people. The hopper gate is prone to jamming due to long-term concrete friction, and manual operation requires considerable physical strength. Furthermore, operation depends on the operator's experience, and fatigue can easily lead to misoperation, affecting the quality of concrete construction and resulting in direct economic losses. In summary, existing technologies suffer from problems such as crude unloading control, easy material sticking and clogging, significant operational safety hazards, low automation, and insufficient structural durability. In the process of high-altitude concrete pouring, the manual opening and closing of the concrete hopper relies heavily on gate handles or insert plates, making it difficult to accurately control the unloading speed. Summary of the Invention

[0005] This invention provides an automatic high-altitude concrete pouring hopper and its pouring method, which can solve the problems of crude unloading control, easy material sticking and clogging, large operational safety hazards, low degree of automation, and insufficient structural durability in the existing technology. In the process of high-altitude concrete pouring, the manual opening and closing of the concrete hopper mostly relies on the gate handle or the insert plate, which makes it difficult to accurately control the material discharge speed. An automatic controlled material pouring hopper for high-altitude concrete includes a loading hopper, a first material gate, and a second material gate. A discharge nozzle is fixedly installed at the lower middle position of the loading hopper. The second material gate and the first material gate are both located at the lower end of the discharge nozzle. The second material gate is located on one side of the first material gate, and the second material gate and the first material gate are arranged in a mirror-symmetrical manner. The loading hopper and the second material gate, as well as the loading hopper and the first material gate, are all connected and fixed by a fixed frame. The first material gate and the second material gate each include a sliding sleeve and a gate plate. The sliding sleeve is located at the lower middle position of the gate plate.

[0006] As a further technical solution of the present invention, two sets of limiting slide rails are fixedly installed on the inner side of the fixed frame to cooperate with the gate. The gate is slidably installed between the two sets of limiting slide rails. The first material gate and the second material gate are both driven by a hydraulic structure to move the gate. When one end of the two gates is closed to each other, it seals the discharge nozzle of the hopper. When the two gates move outward, they open the discharge nozzle of the hopper, so that the concrete in the hopper is discharged downward through the discharge nozzle.

[0007] As a further technical solution of the present invention, both the first and second material gates are provided with hydraulic rods for use with the gate plate. The hydraulic rods are located on the upper part of the gate plate. A hydraulic press for use with the hydraulic rods is provided at the rear end of the fixed frame, and a controller for use with the hydraulic press is provided at the front end of the fixed frame. The hopper and the fixed frame are connected and fixed together by a connecting part. The controller operates the hydraulic press, so that the hydraulic press controls the two hydraulic rods respectively. The hydraulic rods drive the sliding sleeve, so that the sliding sleeve moves along the inner sleeve rod, thereby causing the sliding sleeve to drive the gate plate and complete the opening and closing control of the gate plate.

[0008] As a further technical solution of the present invention, a connector for use with a hydraulic rod is fixedly installed at the upper part of one end of the sliding sleeve. One end of the hydraulic rod is fixedly connected to the connector, and the connector, in conjunction with the threaded sleeve, plays a connecting and fixing role in the installation of the hydraulic rod.

[0009] As a further technical solution of the present invention, the other end of the hydraulic rod is fixedly connected to the discharge nozzle, and a threaded sleeve for use with the hydraulic rod is movably installed on one side of the connector. The user can rotate the threaded sleeve to complete the docking and fixing between the threaded sleeve and the telescopic end of the hydraulic rod by utilizing the thread structure of the threaded sleeve.

[0010] As a further technical solution of the present invention, a docking part is provided on the outer surface of one end of the gate plate. The docking part of the first gate plate is provided with a V-shaped groove, and the docking part of the second gate plate is provided with a V-shaped retaining strip. When the two sets of docking parts move towards each other, the V-shaped groove and the V-shaped retaining strip are docked with each other, thereby improving the sealing effect when the two sets of gate plates are closed and preventing material leakage from the lower end of the discharge nozzle.

[0011] As a further technical solution of the present invention, one end of the gate is provided with inclined scrapers on both sides of the docking part. The surface of the inclined scraper has a bidirectional inclined structure. The surface of the inclined scraper is inclined from top to bottom and simultaneously inclined from one side to the other side, so that the surface of the inclined scraper forms a bidirectional inclined structure. When the inclined scraper of the gate slides in the left and right sets of limit slide rails, the bidirectional inclined scraper can discharge the stones stuck in the slide rail grooves to the outside, thus completing the cleaning operation of the limit slide rails.

[0012] As a further technical solution of the present invention, the lower middle part of the discharge nozzle is inclined to both sides, and the gate and the sliding sleeve are inclined to each other. The inclination angle between the gate and the sliding sleeve is greater than the inclination angle of the lower sides of the discharge nozzle, so that when the sliding sleeve drives the gate to move, the gate and the lower end of the discharge nozzle are in a contact state. With the continuous movement of the gate, the gate is tightly attached to the lower outer surface of the discharge nozzle.

[0013] As a further technical solution of the present invention, the sliding sleeve and one end of the gate are movably connected by a rotating shaft. An elastic part is provided between the sliding sleeve and the gate. The elastic part provides a certain elasticity between the sliding sleeve and the gate. At the same time, in conjunction with the use of the rotating shaft, the angle of the gate can be adjusted. When the sliding sleeve closes and moves, the gate is squeezed by the lower end of the discharge nozzle and makes a corresponding angle change during the movement of the gate. At the same time, the elastic part makes the gate elastically abut against the lower part of the discharge nozzle.

[0014] A method for pouring concrete into an automatic controlled material hopper at high altitudes involves using a controller to operate a hydraulic press, which in turn controls two hydraulic rods. These hydraulic rods drive a sliding sleeve, causing the sliding sleeve to move along the inner sleeve rod. This causes the sliding sleeve to move along two gates, which in turn move along limit rails. The gates control the opening of the discharge nozzle, allowing the concrete in the hopper to be discharged from the discharge nozzle.

[0015] The beneficial effects of this invention are as follows: By setting up a first material gate and a second material gate, this invention enables the high-altitude automatic concrete material control pouring hopper to have a hydraulic gate opening and closing control structure. This eliminates the need for manual opening and closing of the concrete hopper, improving operational efficiency, reducing safety risks, reducing labor intensity, and improving the quality of concrete construction. During operation, both the first and second material gates are driven by a hydraulic structure to move the gates. When one end of the two gates is closed, it seals the discharge nozzle of the hopper. When the two gates move outward, they open the discharge nozzle of the hopper, allowing the concrete in the hopper to be discharged downward through the discharge nozzle. The controller operates the hydraulic press, which controls two hydraulic rods. The hydraulic rods drive the sliding sleeve, causing the sliding sleeve to move along the inner sleeve rod, thereby causing the sliding sleeve to drive the gates. This causes both gates to move along the limit slide rail, and the gates control the opening of the discharge nozzle, allowing the concrete in the hopper to be discharged from the discharge nozzle. By setting up a docking section and an inclined scraper, the gate structure of this high-altitude automatic concrete material control pouring hopper is optimized, improving the sealing performance when the two gates are closed. At the same time, the gates clean the limiting slide rails when they move, preventing them from getting stuck. During operation, when the two sets of docking sections move towards each other, the V-shaped groove and V-shaped clips engage with each other, improving the sealing effect when the two sets of gates are closed and preventing material leakage at the bottom of the discharge nozzle. Secondly, when the inclined scraper of the gate slides in the left and right sets of limiting slide rails, the inclined scraper with bidirectional inclination can discharge the stones stuck in the slide rail grooves, completing the cleaning operation of the limiting slide rails. By incorporating an elastic section and a rotating shaft, this high-altitude automatic concrete material control pouring hopper features an elastic contact structure between the discharge nozzle and the gate. This optimizes the sealing effect between the gate and the discharge nozzle, effectively preventing material leakage, while allowing the gate to move laterally. During operation, the elastic section provides a certain degree of elasticity between the sliding sleeve and the gate. Combined with the rotating shaft, the angle of the gate can be adjusted. When the sliding sleeve closes and moves, the gate is squeezed by the lower end of the discharge nozzle, causing corresponding angle changes during the gate's movement. The elastic section ensures that the gate elastically abuts against the lower part of the discharge nozzle. As the sliding sleeve drives the gate to move, the gate and the lower end of the discharge nozzle are in contact. With the continuous movement of the gate, the gate remains tightly pressed against the lower outer surface of the discharge nozzle. Attached Figure Description

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-4 As shown, an automatic controlled material pouring hopper for high-altitude concrete includes a loading hopper 1, a first material gate 5, and a second material gate 6. A discharge nozzle 3 is fixedly installed at the lower middle position of the loading hopper 1. The second material gate 6 and the first material gate 5 are both located at the lower end of the discharge nozzle 3. The second material gate 6 is located on one side of the first material gate 5, and the second material gate 6 and the first material gate 5 are arranged in a mirror symmetrical manner. The loading hopper 1 and the second material gate 6, as well as the loading hopper 1 and the first material gate 5, are all connected and fixed by a fixing frame 2. The first material gate 5 and the second material gate 6 both include a sliding sleeve 11 and a gate plate 12. The sliding sleeve 11 is located at the lower middle position of the gate plate 12.

[0021] Two sets of limiting slide rails 4 are fixedly installed on the inner side of the fixed frame 2 to cooperate with the gate 12. The gate 12 is slidably installed between the two sets of limiting slide rails 4. The first material gate 5 and the second material gate 6 are both driven by the hydraulic structure to move the gate 12. When one end of the two gates 12 is closed to each other, it seals the discharge nozzle 3 of the hopper 1. When the two gates 12 move outward, the discharge nozzle 3 of the hopper 1 is opened, so that the concrete in the hopper 1 is discharged downward through the discharge nozzle 3.

[0022] In Example 1, both the first material gate 5 and the second material gate 6 are equipped with hydraulic rods 20 that work with the gate plate 12. The hydraulic rods 20 are located on the upper part of the gate plate 12. The rear end of the fixed frame 2 is equipped with a hydraulic press 9 that works with the hydraulic rods 20, and the front end of the fixed frame 2 is equipped with a controller 7 that works with the hydraulic press 9. The hopper 1 and the fixed frame 2 are connected and fixed together by a connecting part 8. The controller 7 controls the hydraulic press 9, so that the hydraulic press 9 controls the two hydraulic rods 20 respectively. The hydraulic rods 20 drive the sliding sleeve 11, so that the sliding sleeve 11 moves along the inner sleeve rod 10, thereby causing the sliding sleeve 11 to drive the gate plate 12 and complete the opening and closing control of the gate plate 12.

[0023] A connector 18 is fixedly installed at the upper part of one end of the sliding sleeve 11 to cooperate with the hydraulic rod 20. One end of the hydraulic rod 20 is fixedly connected to the connector 18. The connector 18, together with the threaded sleeve 19, plays a connecting and fixing role in the installation of the hydraulic rod 20.

[0024] The other end of the hydraulic rod 20 is fixedly connected to the discharge nozzle 3. A threaded sleeve 19 that is used in conjunction with the hydraulic rod 20 is movably installed on one side of the connector 18. The user can rotate the threaded sleeve 19 to complete the docking and fixing between the threaded sleeve 19 and the telescopic end of the hydraulic rod 20 by utilizing the thread structure of the threaded sleeve 19.

[0025] In embodiment 2, a docking part 13 is provided on the outer surface of one end of the gate 12. The docking part 13 of the first material gate 5 is provided with a V-shaped groove 14, and the docking part 13 of the second material gate 6 is provided with a V-shaped retaining strip. When the two sets of docking parts 13 move towards each other, the V-shaped groove 14 and the V-shaped retaining strip are docked with each other, which improves the sealing effect when the two sets of gates 12 are closed and avoids material leakage at the lower end of the discharge nozzle 3.

[0026] One end of the gate plate 12 is provided with inclined scraper heads 15 on both sides of the docking part 13. The surface of the inclined scraper head 15 has a bidirectional inclined structure. The surface of the inclined scraper head 15 is inclined from top to bottom, and the surface of the inclined scraper head 15 is inclined from one side to the other side at the same time, so that the surface of the inclined scraper head 15 forms a bidirectional inclined structure. When the inclined scraper head 15 of the gate plate 12 slides in the left and right sets of limit slide rails 4, the bidirectional inclined scraper head 15 can discharge the stones stuck in the slide groove of the limit slide rail 4, thus completing the cleaning operation of the limit slide rail 4.

[0027] In embodiment 3, the lower middle part of the discharge nozzle 3 is inclined to both sides, and the gate plate 12 and the sliding sleeve 11 are inclined to each other. The inclination angle between the gate plate 12 and the sliding sleeve 11 is greater than the inclination angle of the lower sides of the discharge nozzle 3. When the sliding sleeve 11 drives the gate plate 12 to move, the gate plate 12 is in abutting state with the lower end of the discharge nozzle 3. With the continuous movement of the gate plate 12, the gate plate 12 is tightly attached to the lower outer surface of the discharge nozzle 3.

[0028] The sliding sleeve 11 and one end of the gate 12 are movably connected by a rotating shaft 17. An elastic part 16 is provided between the sliding sleeve 11 and the gate 12. The elastic part 16 provides a certain elasticity between the sliding sleeve 11 and the gate 12. In conjunction with the use of the rotating shaft 17, the angle of the gate 12 can be adjusted. When the sliding sleeve 11 closes and moves, the gate 12 is squeezed by the lower end of the discharge nozzle 3. The gate 12 changes its angle accordingly during the movement. At the same time, the elastic part 16 makes the gate 12 elastically abut against the lower part of the discharge nozzle 3.

[0029] A method for pouring concrete into an automatic controlled material hopper at high altitudes involves using a controller 7 to operate a hydraulic press 9, which in turn controls two hydraulic rods 20. The hydraulic rods 20 drive a sliding sleeve 11, causing the sliding sleeve 11 to move along the inner sleeve rod 10. This causes the sliding sleeve 11 to move the gate 12, resulting in both gates 12 moving along the limiting slide rail 4. The gates 12 control the opening of the discharge nozzle 3, allowing the concrete in the hopper 1 to be discharged from the discharge nozzle 3.

[0030] An automatic high-altitude concrete pouring hopper and its pouring method are disclosed. During operation, the first material gate 5 and the second material gate 6 are both driven by hydraulic structures to move the gate plate 12. When one end of the two gate plates 12 is closed to each other, it seals the discharge nozzle 3 of the hopper 1. When the two gate plates 12 move outward, the discharge nozzle 3 of the hopper 1 is opened, allowing the concrete in the hopper 1 to be discharged downward through the discharge nozzle 3. The controller 7 controls the hydraulic press 9, which controls two hydraulic rods 20 respectively. The hydraulic rods 20 drive the sliding sleeve 11, which moves along the inner sleeve rod 10, thereby causing the sliding sleeve 11 to drive the gate plate 12. Both gate plates 12 move along the limit slide rail 4, and the discharge nozzle 3 is opened by controlling the gate plate 12, allowing the concrete in the hopper 1 to be discharged from the discharge nozzle 3. When the two sets of docking parts 13 move towards each other, the V-shaped groove 14 and the V-shaped retaining strip dock together, improving the sealing effect when the two sets of gates 12 are closed, and preventing material leakage at the lower end of the discharge nozzle 3. Secondly, when the inclined scraper head 15 of the gate 12 slides in the left and right sets of limit slide rails 4, the inclined scraper head 15 with bidirectional inclination can discharge the stones stuck in the slide groove of the limit slide rail 4, completing the cleaning operation of the limit slide rail 4.

[0031] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
