Technical Field
[0001] The utility model relates to the technical field of concrete, in particular to an auxiliary discharging device for a concrete mixer. Background Art
[0002] Concrete, abbreviated as "tóng", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
[0003] After concrete mixing is completed, it is discharged for use. The traditional discharge device has a single structure and cannot quickly open and close the discharge, which easily causes excessive discharge of materials and waste of materials. In addition, most discharge devices lack large aggregate screening and filtering measures. When pouring concrete in densely reinforced building components, it is necessary to strictly control the size of aggregates to avoid oversized aggregates getting stuck in the gaps between steel bars, resulting in the inability of the poured concrete to enter the steel frame, causing the strength of the component to decrease. Therefore, in response to the above problems, an auxiliary discharge device for a concrete mixer is proposed. Utility Model Content

[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.
[0015] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of the auxiliary discharging device for a concrete mixer provided by the utility model. The auxiliary discharging device for a concrete mixer includes a main body 10, an opening and closing mechanism 20 arranged on the main body 10, and a screening mechanism 30 arranged on the main body 10. It can be imagined that the auxiliary discharging device for a concrete mixer also includes other functional modules such as an electrical cabinet, an operation panel, etc., which are well known to those skilled in the art and will not be described one by one here.
[0016] The main body 10 includes a support frame 11 , a work surface 12 disposed on the support frame 11 , and a hopper 13 disposed on the work surface 12 .
[0017] The support frame 11 is a main body for supporting the above structures, including two parallel and spaced support plates, which can be made of rigid materials such as solid wood, stainless steel, alloy, cast iron, etc. to ensure its stability and reliability. The work surface 12 is mounted on the support frame 11 and is parallel to the ground to serve as an operating platform. The hopper 13 is opened on the work surface 12, and the hopper body is a rectangular channel that passes through the work surface 12 and is inserted into the support frame 11. The hopper mouth is funnel-shaped and is located on the other side of the connection between the work surface 12 and the support frame 11, so as to guide the material when the material is put in.
[0018] The opening and closing mechanism 20 includes a fixed shell 21 disposed on the work surface 12 , a driving motor 22 disposed in the fixed shell 21 , a baffle 23 disposed on the driving motor 22 , and a baffle insertion slot 24 disposed on the hopper 13 .
[0019] The fixed housing 21 is a closed rectangular frame fixed on the work surface, with a cavity structure inside, and is located on one side of the hopper 13, and an opening for the baffle 23 to extend out is opened toward the hopper, so as to protect the drive motor 22 and accommodate the baffle 23. The drive motor 22 is arranged inside the fixed housing 21, and can be a servo motor or other drive device, which is not specifically limited here, to drive the baffle 23 to move. One end of the baffle 23 is arranged in the fixed housing 21, and is meshed and connected with the drive motor 23, so that the other end is inserted into or withdrawn from the baffle insertion slot 24 under the driving action of the drive motor 23. The baffle insertion slot 24 is arranged on both sides of the hopper 13, and the baffle insertion slot 24 located on the side close to the fixed housing 21 is provided with an opening for the baffle 23 to be inserted, so that the baffle 23 can be located in the baffle insertion slot 24 when it is fully inserted into the hopper 13, so that the baffle 23 has a strong bearing force in the material input direction.
[0020] The screening mechanism 30 includes a lifting mechanism 31 disposed on the ground, a shock absorbing mechanism 32 disposed on the lifting mechanism 31 , and a vibration screening mechanism 33 disposed on the shock absorbing mechanism 32 .
[0021] The lifting mechanism 31 includes two bottom plates 311 disposed on the ground, and two electro-hydraulic push rods 312 disposed on the bottom plates 311. The bottom plates 311 are disposed on the ground, and the two bottom plates 311 are axially symmetrical with the hopper 13 as an axis, so as to place and support the electro-hydraulic push rods 312. The electro-hydraulic push rods 312 are a driving device, and are used to drive the vibrating screening mechanism 33 to move in the vertical direction.
[0022] The shock absorbing mechanism 32 includes two fixed blocks 321 respectively arranged on the electro-hydraulic push rod 312, two shock absorbing rubber pads 322 respectively arranged in the fixed blocks 321, two telescopic rods 323 respectively arranged on the shock absorbing rubber pads 322, and two shock absorbing springs 324 respectively sleeved on the telescopic rods 323. The fixed block 321 is divided into upper and lower blocks, which are respectively connected to the electro-hydraulic push rod 312 and the telescopic rod 323, and the shock absorbing rubber pad 322 is arranged in the middle to reduce the vibration transmission of the vibration screening mechanism 33 and avoid damage to the electro-hydraulic push rod 312. The telescopic rod 323 and the shock absorbing spring 324 are arranged between the fixed block 321 and the vibration screening mechanism 33 to cooperate with the vibration screening mechanism 33 to vibrate.
[0023] The vibrating screening mechanism 33 includes two connecting plates 331 connected to the telescopic rod 323, two vibration motors 332 arranged on the connecting plates 331, and a screening hopper 333 connected to the two connecting plates 331. The connecting plates 331 are respectively fixed to the telescopic rods 323 and are respectively located on both sides of the hopper 13, so as to connect and fix the screening hopper 333. The vibration motor 332 is fixed to the connecting plates 331, and drives the screening hopper 333 to vibrate and screen materials by vibrating the connecting plates 331. The screening hopper 333 is connected between the two connecting plates 331 and is located directly below the discharge port of the hopper 13, so that the materials put into the hopper 13 will fall into the screening hopper 333. The bottom of the screening hopper 333 is a screen to filter the physical falling into the screening hopper 333. It can be imagined that after the material falls into the screening hopper 333, it is vibrated by the vibration motor 332 so that the concrete can be quickly retained. At the same time, the aggregate with too large particle size in the concrete is filtered through the filter of the screening hopper 333. When there are many large-size aggregates filtered out in the screening hopper 333, the screening hopper 333 is lowered by shortening the electro-hydraulic push rod 312, and the large-size aggregates in the screening hopper 333 are cleaned to ensure smooth passage of concrete.
[0024] Compared with the prior art, the auxiliary discharging device for a concrete mixer provided by the utility model is provided with the hopper 13 to discharge material downward, and the baffle 23 is driven to be withdrawn from the hopper 13 by the driving motor 22, so that the hopper 13 is opened, and concrete passes through the hopper 13 and enters the screening hopper 333. When the hopper 13 needs to be closed, the baffle 23 is driven to be inserted into the baffle insertion slot 24 by the reverse rotation of the driving motor 22, and the discharge is quickly stopped to avoid excessive discharge and material waste, and the operation is convenient. At the same time, the vibration motor 332 is provided to drive the connecting plate 331 to vibrate, so that the concrete can flow down quickly from the screening hopper 333, and the aggregate with too large particle size in the concrete is filtered to avoid the aggregate with too large particle size being poured into the building structure, which causes the quality problems of the concrete structure.
