Description

Technical Field

[0001] The present application relates to the technical field of determination of the water - binder ratio of concrete, and particularly relates to a device for rapidly determining the water - binder ratio of concrete. Background Art

[0002] The device for rapidly determining the water - binder ratio of concrete is an instrument used at the construction site of concrete pouring to comprehensively manage the mix proportion of concrete before it is poured into the mold.

[0003] Currently, for the device for rapidly determining the water - binder ratio of concrete, the top of its box body is a sealing cover. A driving member is fixedly installed on the top of the sealing cover. One end of the driving member is provided with a rotating shaft, and stirring blades are fixedly installed on the rotating shaft. The rotating shaft and the stirring blades are located inside the box body. During operation, the driving member is used to drive the rotating shaft to rotate, so that more moisture in the concrete can evaporate, thereby achieving the functions of stirring, accelerating the drying of the concrete, and improving the test efficiency.

[0004] When the sealing cover is closed, when the stirring shaft and the stirring blades are inserted downward into the concrete, they are subject to the resistance of the concrete and need to overcome a large resistance to insert the stirring shaft and the stirring blades into the inside of the box body to realize the closing of the sealing cover, which is rather troublesome and needs to be improved. Content of the Utility Model

[0005] The purpose of the present application is to provide a device for rapidly determining the water - binder ratio of high - performance concrete to improve the resistance when the sealing cover is closed and enhance the working efficiency of water - binder ratio determination.

[0006] The device for rapidly determining the water - binder ratio of high - performance concrete provided by the present application adopts the following technical solutions:

[0007] A device for rapidly determining the water - binder ratio of concrete includes a drying box body and a cover body for covering the drying box body. A stirring part is arranged inside the drying box body. The stirring part includes a stirring shaft and stirring blades. An installation hole for inserting the lower end of the stirring shaft is arranged on the bottom wall of the drying box body. The cover body is provided with a driving member, and the driving shaft of the driving member penetrates through the cover body and is connected to the stirring shaft. The upper end of the stirring shaft is a prism, and the driving shaft of the driving member is provided with a sleeve, and the sleeve is sleeved on the upper end of the stirring shaft. The inner side wall of the sleeve is matched with the upper end of the stirring shaft.

[0008] By adopting the above technical solutions, when it is necessary to measure the water - binder ratio of concrete, the operator can insert the stirring shaft and the stirring blades into the installation hole at the bottom of the drying box, pour the concrete or material to be measured into the drying box, then insert the sleeve and the upper end of the stirring shaft, and at the same time, the cover body covers the drying box body. Since the stirring shaft and the stirring blades do not need to overcome the resistance of the concrete, the working efficiency is improved, and the working efficiency of water - binder ratio determination is enhanced.

[0009] Preferably, a bearing for inserting the stirring shaft is embedded inside the installation hole.

[0010] By adopting the above technical solution, the bearing effectively reduces the friction between the stirring shaft and the inner wall of the mounting hole; the stirring shaft contacts the inner wall of the mounting hole through the bearing, thereby reducing the frictional force between the stirring shaft and the inner wall of the mounting hole, and making the stirring of the stirring shaft smoother.

[0011] Preferably, a sealing gasket is provided above the bearing in the mounting hole.

[0012] By adopting the above technical solution, when the driving member operates, it drives the driving shaft to rotate, causing the bearing to rotate. Setting a sealing gasket on the bearing can effectively protect the bearing and increase the service life of the bearing.

[0013] Preferably, a fixing ring is threadedly connected to the inner wall of the mounting hole, and the lower surface of the fixing ring abuts against the upper surface of the sealing gasket.

[0014] By adopting the above technical solution, a fixing ring is provided on the top of the sealing ring to ensure that the sealing ring remains in contact with the bearing during rotation. The sealing gasket can block the concrete from entering the bearing interior and reduce the entry of concrete into the bearing.

[0015] Preferably, a positioning cone is fixedly provided on the upper end surface of the stirring shaft.

[0016] By adopting the above technical solution, since the positioning cone is in a conical shape, it is convenient to insert into the sleeve, and the stirring shaft can be quickly inserted into the sleeve interior to achieve quick connection.

[0017] Preferably, a through hole is provided on one side of the cover body where the driving member is located, and a visual plate is fixed to the inner wall of the through hole.

[0018] By adopting the above technical solution, a through hole is provided on one side of the sealing cover where the driving member is located, and a transparent plate is fixed to the inner wall of the through hole, which is convenient for observing the measurement progress and can also assist in the sleeving of the driving shaft and the stirring shaft. A through hole is provided on one side of the sealing cover where the driving member is located, and a transparent plate is fixed to the inner wall of the through hole, which is convenient for observing the progress of the concrete drying state and can also assist in the sleeving of the driving shaft and the stirring shaft through perspective observation.

[0019] Preferably, a positioning convex ring is provided on the inner wall of the through hole on the side away from the driving member.

[0020] By adopting the above technical solution, a positioning convex ring is provided on the inner wall of the through hole to fix the visual plate, effectively preventing the visual plate from falling off due to the vibration of the device.

[0021] Preferably, a magnet that magnetically attracts the cover body is fixed to the outer surface of the visual plate.

[0022] By adopting the above technical solution, a magnet magnetically attracted to the cover body is fixed on the outer surface of the visual board, so that the visual board is adsorbed on the sealing cover for convenient regular disassembly, cleaning and installation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. An installation hole for inserting the lower end of the stirring shaft is provided on the bottom wall of the drying box body, and a driving member is provided on the cover body.
