Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete raw material silo with a feeding structure. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water in a certain proportion. It is widely used in civil engineering.

[0003] In concrete production, raw materials are transported to storage sites by trucks, and then aggregates are transported to raw material silos by forklifts and other transport tools. After being metered by the raw material silos, the aggregates are discharged into the output equipment and then conveyed to the mixer for mixing. The use of forklifts and other transport tools to transport aggregates to the raw material silos can easily cause dust to fly up during the feeding process, polluting the environment. To solve this problem, we propose a concrete raw material silo with a feeding structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete raw material silo with a feeding structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete raw material silo with a feeding structure, including a silo body and an aggregate storage seat. The aggregate storage seat has a downwardly inclined discharge channel connected to its side. The other end of the discharge channel is provided with a discharge buffer seat. The lower end of the discharge buffer seat is provided with a discharge cylinder. A switch seat is connected inside the discharge cylinder. The discharge buffer seat is provided with a lifting switch assembly. The lifting switch assembly is provided with a sealing head. The opening and closing of the switch seat opening is achieved by moving the sealing head up and down.

[0006] A conveyor sealing cover is connected between the hopper body and the lower end of the feeding cylinder, and a belt conveyor with the same length and width as the conveyor sealing cover is installed inside the conveyor sealing cover.

[0007] Using the above technical solution, aggregates are centrally stored in the aggregate storage seat and discharged into the discharge buffer seat through the discharge channel. The lifting switch assembly drives the sealing head to move, opening the opening of the switch seat located in the discharge cylinder, allowing the aggregates to be discharged into the conveyor sealing cover through the discharge cylinder, and then transported to the silo by the belt conveyor for feeding. This realizes automatic feeding of aggregates after storage and feeding in a closed environment.

[0008] As a preferred embodiment of this utility model, the lower end of the silo is provided with a discharge pipe, and an automatic switching valve is connected to the outside of the discharge pipe.

[0009] By adopting the above technical solution, the aggregate stored in the silo is discharged through the discharge pipe by opening the automatic switching valve.

[0010] As a preferred embodiment of this utility model, the sealing head is a frustum with an upper diameter smaller than the lower diameter, and the switch base is funnel-shaped with its inner wall sloping downwards.

[0011] By adopting the above technical solution, the inner wall of the switch seat is set with a sloping surface, so that the aggregate slides out along the sloping surface to the sloping surface of the sealing head, which buffers the material and reduces the impact of the aggregate discharge on the belt conveyor, thus avoiding damage to the belt conveyor.

[0012] As a preferred embodiment of the present invention, the lifting switch assembly includes a guide seat disposed on the upper end of the feeding buffer seat, a hydraulic push rod disposed on the upper end of the guide seat, a movable seat disposed on the push rod of the hydraulic push rod that slides outside the guide seat, and a connecting rod disposed on the movable seat that connects to the upper end of the sealing head.

[0013] Using the above technical solution, the hydraulic push rod pushes the movable seat to move on the guide seat, and simultaneously drives the sealing head on the connecting rod to move, thereby opening and closing the opening of the switch seat.

[0014] In a preferred embodiment of this utility model, the connecting rod and the sealing head are arranged concentrically, a drive motor is provided at the upper end of the movable seat, the output end of the drive motor is connected to the connecting rod, and a plurality of actuating levers are provided on the outside of the connecting rod.

[0015] Using the above technical solution, the drive motor drives the sealing head and the actuating rod to rotate synchronously, thereby actuating the aggregate at the discharge port and avoiding discharge blockage.

[0016] As a preferred embodiment of this utility model, the aggregate storage seat is open on the side opposite to the discharge channel. Guide rail grooves are provided on both the front and rear sides of the inner cavity of the aggregate storage seat. A push plate that slides between the guide rail grooves and is in contact with and sealed to the inner wall of the aggregate storage seat is provided on the aggregate storage seat. A hydraulic push rod connected to the push plate is provided on the aggregate storage seat.

[0017] Using the above technical solution, the hydraulic push rod works to push the push plate to move in the guide rail groove, thereby promoting the discharge of the aggregate stored in the aggregate storage seat into the discharge channel.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This concrete raw material silo with a feeding structure centrally stores aggregates through an aggregate storage seat and discharges them into a discharge buffer seat through a discharge channel. The lifting switch assembly drives the sealing head to move, opening the opening of the switch seat located in the discharge cylinder, allowing the aggregates to be discharged through the discharge cylinder into the conveyor sealing cover. The aggregates are then conveyed into the silo body by a belt conveyor for feeding, realizing automatic feeding after aggregate storage and feeding in a closed environment. Compared with existing technologies, this achieves dust-free feeding and achieves the goal of environmental protection.

[0020] 2. The concrete raw material silo with feeding structure has an inner wall sloping surface on the switch seat, which allows the aggregate to slide out along the sloping surface to the sloping surface of the sealing head, buffering the material and reducing the impact of the aggregate discharge on the belt conveyor, thus avoiding damage to the belt conveyor. The drive motor drives the sealing head and the actuating rod to rotate synchronously, thereby actuating the aggregate at the discharge port to avoid discharge blockage. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 5 The concrete raw material silo with feeding structure in this embodiment mainly consists of a silo body 1 and an aggregate storage seat 4. The aggregate storage seat 4 has a downwardly inclined discharge channel 8 connected to its side, and a discharge buffer seat 9 connected to its other end. The lower end of the discharge buffer seat 9 is connected to a discharge cylinder 10. A switch seat 17 is connected inside the discharge cylinder 10. A lifting switch assembly is installed on the discharge buffer seat 9. The assembly is equipped with a sealing head 18 that can move up and down to control the opening and closing of the switch seat 17. The silo body 1 and the lower end of the discharge cylinder 10 are connected by a conveyor sealing cover 19. A belt conveyor 20 with the size matching the conveyor sealing cover 19 is installed inside.

[0029] It should be added that the belt conveyor 20 is existing technology, and the conveyor belt of the belt conveyor 20 is in close contact and sealed with the inner wall of the conveyor sealing cover 19.

[0030] The aggregate storage seat 4 is used to store a large amount of aggregate. Its side is connected to an inclined downward discharge channel 8, which allows the aggregate to slide smoothly into the discharge buffer seat 9. The discharge buffer seat 9 is connected to the discharge cylinder 10, which plays a role in buffering the impact of the falling aggregate. The switch seat 17 is located inside the discharge cylinder 10 and is funnel-shaped with a downward slope on the inner wall, which facilitates the sliding out of the aggregate and also reduces the impact on the subsequent belt conveyor 20.

[0031] The sealing head 18 is a key part of the lifting switch assembly. It is shaped like a frustum with a small diameter at the top and a large diameter at the bottom. When the lifting switch assembly is working, the sealing head 18 moves up and down, thereby precisely controlling the opening and closing of the switch seat 17 and effectively regulating the aggregate feeding process.

[0032] The lifting switch assembly is installed on the upper end of the unloading buffer seat 9, including the guide seat 11, which is fixed on the upper surface of the unloading buffer seat 9 and serves to guide the moving seat 13 to slide outside the guide seat 11. The hydraulic push rod 12 is installed and fixed on the upper surface of the guide seat 11 and pushes the moving seat 13 to slide along the outer wall of the guide seat 11. The connecting rod 15 connects and fixes the lower end of the moving seat 13 and the upper end of the sealing head 18, ensuring that the sealing head 18 moves stably together with the moving seat 13.

[0033] A drive motor 14 is fixed to the upper end of the movable seat 13 by bolts. Its output end is connected and fixed to the connecting rod 15. Multiple actuating rods 16 are mounted and fixed on the outside of the connecting rod 15. When the aggregate is fed, the drive motor 14 drives the connecting rod 15 and the actuating rods 16 to rotate. The actuating rods 16 actuate the aggregate at the feeding port to prevent the aggregate from blocking and ensure smooth feeding.

[0034] The conveyor sealing cover 19 connects the bin body 1 and the lower end of the discharge cylinder 10 to form a closed conveying channel. The belt conveyor 20 is placed inside the conveyor sealing cover 19, and its length and width are consistent with the conveyor sealing cover 19, so as to ensure that the aggregate can be stably conveyed to the bin body 1 in a sealed environment.

[0035] The lower end of the silo 1 is connected to a discharge pipe 2, which is connected to an automatic switch valve 3 to control the discharge of aggregate in the silo 1. The operation is convenient and the output of aggregate can be adjusted in a timely manner according to production needs.

[0036] The aggregate storage seat 4 is open on the side opposite to the discharge channel 8. The front and rear side walls inside are provided with guide rail grooves 5, in which the push plate 6 can slide and fit tightly against the inner wall of the aggregate storage seat 4 to ensure sealing. The hydraulic push rod 7 is installed and fixed on the side of the aggregate storage seat 4, and the push rod is connected and fixed to the push plate 6. During operation, the hydraulic push rod 7 pushes the push plate 6 to move along the guide rail grooves 5, pushing the aggregate in the aggregate storage seat 4 evenly into the discharge channel 8, thereby improving the discharge efficiency of the aggregate.

[0037] It is equipped with a PLC-based automated control system to achieve centralized control of the entire silo feeding process.

[0038] Working principle and usage steps: Aggregate is loaded into aggregate storage seat 4 through the open side of aggregate storage seat 4. When it is necessary to feed material into bin 1, the hydraulic push rod 7 is activated to push the push plate 6 to slide in the guide rail groove 5, so that the aggregate in aggregate storage seat 4 is evenly pushed into the discharge channel 8. Under the action of the aggregate's own gravity, the aggregate slides down the inclined discharge channel 8 to the discharge buffer seat 9.

[0039] At this time, the hydraulic push rod 12 pushes the moving seat 13 to slide downward along the guide seat 11, and drives the sealing head 18 to move downward through the connecting rod 15, opening the opening of the switch seat 17. After the aggregate is briefly buffered in the feeding buffer seat 9, it continues to fall into the feeding cylinder 10, and then is discharged into the conveying sealing cover 19 through the switch seat 17. The belt conveyor 20 in the conveying sealing cover 19 starts, and the aggregate is stably and evenly conveyed into the bin 1 along the sealed channel, completing the feeding operation.

[0040] If the aggregate feeding process is obstructed or blocked, the drive motor 14 will start immediately, driving the connecting rod 15 and the actuating rod 16 to rotate. The actuating rod 16 agitates the aggregate at the feeding port, loosening the aggregate and restoring smooth feeding. At the same time, the frustum shape of the sealing head 18 matches the funnel-shaped structure of the switch base 17, allowing the aggregate to slide out smoothly under the guidance of the slope, slowing down the feeding speed, reducing the impact on the belt conveyor 20, and further preventing blockage.

[0041] After the equipment has been running for a period of time, if it is necessary to discharge the aggregate in the bin 1, the automatic switch valve 3 on the discharge pipe 2 can be opened. The aggregate will be discharged through the discharge pipe 2 under the action of gravity and enter the next production process.

[0042] Beneficial effects: Through the design of aggregate storage seat 4 and conveying sealing cover 19, the entire feeding process is carried out in a closed environment, effectively avoiding the dust problem generated when feeding with a traditional loader. This not only improves the environmental quality of the production site and protects the health of the workers, but also meets the strict environmental protection requirements of modern industry and reduces pollution to the surrounding environment.

[0043] The combination of the sloping surface of the switch base 17 and the frustum shape of the sealing head 18 provides a good buffer for the discharged aggregate, effectively controlling the speed of the aggregate during its descent, reducing the impact on the belt conveyor 20, and extending the service life of the equipment. At the same time, the setting of the drive motor 14 and the toggle lever 16 can promptly handle the problem of blockage at the discharge port, ensuring the smooth discharge of aggregate and providing a stable supply of raw materials for subsequent concrete production.

[0044] In summary, the concrete raw material silo with feeding structure in this embodiment, through innovative structural design, successfully solves the dust and blockage problems existing in aggregate feeding in traditional concrete production, and realizes environmentally friendly and efficient automated feeding. It provides concrete production enterprises with a high-performance and practical raw material storage and feeding solution, which has significant application value and promotion prospects.

[0045] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
