Description

Technical Field

[0001] This utility model relates to the field of fine aggregate concrete mixing technology, specifically a fine aggregate concrete precision mixing device for truss plate production. Background Technology

[0002] Truss panels are an innovative building material, mainly used in building roof design. They are typically constructed by pouring fine aggregate concrete between two parallel steel frames to form a base, thereby providing support and allowing for non-removal.

[0003] The production of fine aggregate concrete requires thorough mixing of fine aggregate and concrete. During mixing, some raw materials adhere to the inner wall of the mixing drum, which is difficult to clean and requires workers to spend a lot of time scraping them off, reducing work efficiency and affecting subsequent mixing. Utility Model Content

[0004] To address the problem of raw materials adhering to the inner wall of the mixing drum during mixing and being difficult to clean, the purpose of this utility model is to provide a fine aggregate concrete precision mixing device for truss plate production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fine stone concrete precision mixing and stirring device for truss plate production, comprising a tank body, a rotating shaft passing through the center of the tank body, a connecting sleeve rotatably sleeved on the rotating shaft, the connecting sleeve rotatably passing through the top of the tank body, two symmetrically distributed fixed shafts fixedly connected to the bottom of the connecting sleeve, a circular plate fixedly connected to both ends of the two fixed shafts, a diversion pipe fixedly connected to the bottom of the circular plate, multiple nozzles fixedly connected to the bottom of the diversion pipe, multiple scrapers fixedly connected to the bottom of the circular plate, a spiral stirring block fixedly installed on the rotating shaft inside the tank body, and a feeding device provided at the top of the tank body.

[0006] Preferably, the feeding device includes a feeding trough, which is trapezoidal, and a storage frame is fixedly connected to the top of the feeding trough. A partition is fixedly provided in both the feeding trough and the storage frame.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This utility model uses a motor to drive the second bevel gear to rotate, which in turn drives the first bevel gear to rotate the shaft and the stirring block. The third bevel gear, which rotates in the opposite direction, drives the scraper to assist in stirring. When it is necessary to clean the tank, the inner wall is cleaned by the diversion pipe and the nozzle in conjunction with the scraper, so that the raw materials will not remain inside the tank, reducing the workload of the staff and improving work efficiency.

[0009] 2. By pouring different raw materials into the storage boxes on both sides of the partition, it is more convenient to feed them later. After pouring, the baffle is pulled by the handrail to allow the raw materials to be added into the tank through the feed chute for stirring. Attached Figure Description

Two symmetrically distributed baffles 32 are slidably connected at the connection between the feeding trough 3 and the storage frame 34. A handrail 33 is fixedly connected to one end of the baffle 32. By pouring different raw materials into the storage frames 34 on both sides of the partition 31, it is more convenient to discharge the materials. After pouring, the baffle 32 is pulled by the handrail 33 to allow the raw materials to enter the tank 1 through the feeding trough 3 for stirring.

[0020] A discharge pipe 41 is fixedly provided at the bottom of the tank body 1, and a control valve 42 is provided on the discharge pipe 41; the discharge is controlled by the discharge pipe 41 and the control valve 42.

[0022] A first bevel gear 21 is fixedly provided near the top of the rotating shaft 2, and a third bevel gear 23 is fixedly provided on the top of the connecting sleeve 231 and sleeved on the rotating shaft 2. A second bevel gear 22 is meshed between the first bevel gear 21 and the third bevel gear 23. The rotation of the second bevel gear 22 drives the first bevel gear 21 and the third bevel gear 23 to rotate in opposite directions.

[0025] Working principle: First, the staff pours different raw materials into the storage boxes 34 on both sides of the partition 31. After pouring, the baffle 32 is pulled by the handle 33 so that the raw materials are added into the tank 1 through the feed chute 3 for stirring. Then, the motor 5 is started, and the second bevel gear 22 is driven to rotate, so that the first bevel gear 21 drives the rotating shaft 2 and the stirring block 24 to rotate. The third bevel gear 23 rotating in the opposite direction drives the scraper 235 to perform auxiliary stirring. When the stirring is completed, the control valve 42 is opened so that the mixed raw materials enter the collection box 4 from the feed pipe 41, which is convenient for the staff to carry out the next operation.

[0026] When cleaning is required, the motor 5 is started and water is sprayed into the tank 1 through the diversion pipe 233 and the nozzle 234. The motor 5 drives the scraper 235 to clean the inner wall of the tank 1, so that the raw materials will not remain inside the tank, reducing the workload of the staff and improving work efficiency.
