Description

Technical Field

[0001] This utility model belongs to the field of concrete production technology, specifically relating to a storage silo for a concrete mixing plant in bridge construction. Background Technology

[0002] In bridge construction, concrete, as a crucial construction material, directly impacts the overall quality and construction progress of bridge projects through its quality and supply stability. Traditionally, concrete mixing plants used in bridge construction employ a single-bin design for single-material storage, meaning each silo can only store one specific material, such as cement, sand, or gravel. This not only increases the number of silos used but also requires a separate motor for the discharging mechanism of each material. On one hand, the large number of motors increases equipment purchase costs and energy consumption, leading to higher operating costs for the mixing plant. On the other hand, maintaining and servicing numerous motors requires significant manpower, resources, and time, further increasing the maintenance costs and complexity of the mixing plant. Utility Model Content

[0003] The purpose of this invention is to provide a storage silo for a concrete mixing plant in bridge construction, which solves the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A storage silo for a concrete mixing plant in bridge construction includes a support frame. Two symmetrically distributed material silos are fixed to the upper side of the support frame. A hopper is connected to the lower side of each material silo. A discharge pipe is horizontally connected to the lower side of each hopper. One end of the discharge pipe has a discharge port. A matching auger is rotatably mounted inside the discharge pipe. A power unit is fixed between the two hoppers. A rotating rod, which is rotatably connected to the power unit, is rotatably mounted on the lower side of the power unit. Connecting blocks are fixed to both ends of the rotating rod. A circular cavity is formed inside each connecting block. A ratchet is rotatably mounted inside the circular cavity, with the ratchet teeth of the two ratchets facing opposite directions. A pawl, hinged to the connecting block and matching the ratchet, is mounted on the side of the ratchet. A spring plate, fixed to the side wall of the circular cavity, is fixed to the side of the pawl. A transmission rod, rotatably connected to the connecting block and fixedly connected to the ratchet, is mounted on the outer side of the connecting block. Each transmission rod is rotatably connected to the corresponding lower auger.

[0006] Two loosening rods are rotatably mounted on the upper side of the auger, distributed front to back and rotatably connected to the hopper. The left and right ends of the loosening rods extend outward from the outside of the hopper. Multiple loosening columns are evenly fixed in the middle of the loosening rods. Two first sprockets and one second sprocket are rotatably mounted on the outside of the hopper. The first sprockets are fixedly connected to the loosening rods, and the second sprockets are driven by the auger. A chain is connected between the two first sprockets and the second sprocket. Each drive rod is driven by one of the loosening rods on the same side.

[0007] The two discharge ports on the left and right are close to each other.

[0008] The side of the hopper is fixed with a protective shell that matches the first sprocket, the second sprocket, and the chain.

[0009] Multiple diagonal rods are fixed to the upper side of the bracket.

[0010] The dual-material silo configuration helps reduce the overall number of silos required by the mixing plant. The discharge mechanism, employing a discharge pipe with an auger and a power unit with left and right forward and reverse ratchet and pawl mechanisms, replaces the dual-motor drive system with a single motor. This directly reduces the procurement costs of core components such as motors, reducers, and frequency converters, and lowers the complexity of the electrical system. Simultaneously, halving the number of motors reduces the overall equipment weight, facilitating transportation and installation, and further reducing daily maintenance time and costs. The first and second sprockets and chains, along with multiple evenly fixed loosening columns on the loosening rod, ensure that the two loosening columns rotate synchronously with the auger during operation. This eliminates the need for an additional power mechanism and prevents material blockage in the hopper or discharge pipe, guaranteeing smooth material discharge from the silo. The symmetrical distribution of the two material silos and their close proximity to each other facilitates concentrated discharge, improving efficiency. The protective shell on the outside of the hopper prevents external dust and debris from contacting the sprockets and chain, extending their service life. The diagonal brace and support enhance the overall stability of the silo. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-5 As shown, a storage silo for a concrete mixing plant in bridge construction includes a support 101. Two symmetrically distributed material silos 102 are fixed to the upper side of the support 101. A hopper 103 is connected to the lower side of each material silo 102. A discharge pipe 104 is horizontally connected to the lower side of each hopper 103. A discharge port 105 is opened at one end of the discharge pipe 104. A matching auger 106 is rotatably installed inside the discharge pipe 104. A power unit 107 is fixed between the two hoppers 103. A rotating rod 108, which is rotatably connected to the power unit 107, is rotatably installed on the lower side of the power unit 107. The rotating rod 108 rotates left and right. Both ends are fixed with connecting blocks 109. A cavity 110 is opened on the inner side of the connecting block 109. A ratchet 111 is rotatably installed on the inner side of the cavity 110, and the ratchet teeth of the two ratchets 111 are in opposite directions. A pawl 112 is installed on the side of the ratchet 111, which is hinged to the connecting block 109 and matches the ratchet 111. A spring plate 113 is fixed on the side of the pawl 112 and fixed to the side wall of the cavity 110. A transmission rod 114 is installed on the outer side of the connecting block 109, which is rotatably connected to the connecting block 109 and fixedly connected to the ratchet 111. Each transmission rod 114 is connected to the auger 106 on the corresponding lower side.

[0020] The power unit 107 is a combination of a traditional reduction gearbox and a motor. The cooperation of the connecting blocks 109, ratchet 111 and pawl 112 on the left and right sides of the rotating rod 108, and the opposite direction of the ratchet teeth of the ratchet 111 on the left and right sides, enables the power unit 107 to rotate in both directions, thereby driving the different augers 106 on the left and right sides to rotate, thereby controlling the discharge of different discharge pipes 104 on the left and right sides.

[0021] The dual material storage bins 102 help reduce the overall number of storage bins required by the mixing plant. The discharge mechanism, using a discharge pipe 104 in conjunction with an auger 106 and a power unit 107 with left and right forward and reverse ratchet and pawl mechanisms, replaces the dual-motor drive system with a single motor. This directly reduces the procurement costs of core components such as motors, reducers, and frequency converters, as well as lowers the complexity of the electrical system. Simultaneously, halving the number of motors reduces the overall equipment weight, facilitating transportation and installation, and further reducing daily maintenance time and costs.

[0022] Two loosening rods 201 are rotatably mounted on the upper side of the auger 106, distributed front to back and rotatably connected to the hopper 103. The left and right ends of the loosening rods 201 extend out of the hopper 103. Multiple loosening columns 202 are evenly fixed in the middle of the loosening rods 201. Two first sprockets 203 and one second sprocket 204 are rotatably mounted on the outer side of the hopper 103. The first sprockets 203 are fixedly connected to the loosening rods 201, and the second sprocket 204 is driven by the auger 106. A chain 205 is connected between the two first sprockets 203 and the second sprocket 204. Each drive rod 114 is driven by one of the loosening rods 201 on the same side.

[0023] The first sprocket 203, the second sprocket 204, and the chain 205 are set up and cooperate to evenly fix multiple loosening columns 202 on the loosening rod 201, so that the two loosening rods can rotate synchronously with the auger 106 when it is working. This prevents the material from getting stuck in the hopper 103 or the discharge pipe 104 without the need for an additional power mechanism, thus ensuring smooth material discharge from the storage bin.

[0024] The two discharge ports on the left and right are close to each other.

[0025] The side of the hopper 103 is fixed with a protective shell 401 that matches the first sprocket 203, the second sprocket 204 and the chain 205.

[0026] Multiple diagonal rods 501 are fixed on the upper side of the bracket 101.

[0027] The two material bins 102 are symmetrically distributed on the left and right, and the discharge ports 105 are close to each other, which facilitates centralized material discharge and improves discharge efficiency. The protective shell 401 on the outside of the hopper 103 can prevent external dust and debris from contacting the sprocket and chain 205, which helps to extend their service life. The inclined bar 501 and the bracket 101 work together to enhance the overall stability of the storage bin.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
