Description

Technical Field

[0001] This utility model relates to the field of cement mortar flowability testing technology, and in particular to a cement mortar flowability testing instrument. Background Technology

[0002] Cement mortar flowability is a measure of the fluidity of cement mortar. Under a certain amount of water, cement mortar flowability reflects the plasticity of cement mortar. Flowability is used to control the amount of water used for cement mortar strength molding. Cement mortar flowability depends on the water demand of cement and is expressed as the average diameter of the cement mortar spreading on a flow table.

[0003] However, existing cement mortar flowability testers all use cams to achieve vibration. The manufacturing of cams is extremely complex, and cams are prone to wear. Furthermore, they are prone to accumulation during mortar cleaning, which can easily affect the accuracy of cement mortar flowability measurement. Therefore, those skilled in the art have provided a cement mortar flowability tester to solve the problems mentioned in the background art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cement mortar flowability tester, which aims to improve the problem in the prior art that the accumulation of cement mortar during cleaning can easily affect the accuracy of cement mortar flowability measurement.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cement mortar flowability tester includes a base, a motor fixedly connected to the upper right side of the base, a rotating shaft fixedly connected to the output end of the motor, a turntable fixedly connected to the right side of the rotating shaft, an adjustment hole inside the turntable, a fixed frame fixedly connected to the upper part of the base, a sleeve fixedly connected to the inner side of the fixed frame, a jump rod inside the sleeve, a drive frame fixedly connected to the lower part of the jump rod, a support rod inside the drive frame, a threaded head on the left side of the support rod, a jump table fixedly connected to the upper part of the jump rod, a conical mold on the upper part of the jump table, and a cleaning component on the upper right side of the jump table.

[0007] With the above technical solution, by starting the motor, the output end of the motor drives the rotating shaft to rotate, the rotating shaft drives the turntable to rotate, and as the turntable rotates, it drives the support rod fixed on the turntable to rotate. The rotation of the support rod drives the drive frame to rotate, and the drive frame drives the jumping rod to move up and down inside the sleeve. The jumping rod vibrates up and down on the jumping table. By rotating the support rod, the threaded head of the support rod is turned out from the adjustment hole on the turntable. The jumping rod is slid up and down to adjust its position. Then, the threaded head is threaded into the designated adjustment hole for fixation, thereby adjusting the stroke of the up and down movement and adjusting the amplitude of the jumping table.

[0008] Furthermore, the cleaning assembly includes a cylinder, which is fixedly connected to the lower part of the jumping table. An L-shaped rod is fixedly connected to the telescopic end of the cylinder, and a sliding block is fixedly connected to the upper part of the L-shaped rod. Fixed plates are fixedly connected to the front and rear sides of the jumping table. A sliding rod is fixedly connected to the inner side of the fixed plate on the same horizontal plane. The sliding block is disposed outside the sliding rod. A connecting frame is fixedly connected to the upper part of the sliding block. A scraper is fixedly disposed at the lower part of the connecting frame. A filter box is disposed inside the left side of the jumping table. A filter screen is disposed inside the filter box. A collection box is fixedly connected to the upper left side of the base.

[0009] The above technical solution involves starting the cylinder, which causes the extension end of the cylinder to move the L-shaped rod. The L-shaped rod then causes the sliding block to slide outside the sliding rod, thereby causing the sliding block to move the connecting frame. The scraper at the bottom of the connecting frame scrapes the cement mortar remaining on the table into the filter box. The mortar is then filtered through the filter screen inside the filter box and collected in the collection box. This effectively scrapes off and cleans the residual cement mortar.

[0010] Furthermore, a connecting rod is fixedly connected to the outside of the conical mold, and an electric push rod is fixedly connected to the outside of the connecting rod. The bottom of the electric push rod is fixedly connected to the front and rear sides of the upper part of the base.

[0011] The above technical solution involves activating an electric push rod, which, via a connecting rod, moves the conical mold upwards, facilitating subsequent cleaning.

[0012] Furthermore, the threaded head is threaded into the interior of the adjusting hole.

[0013] By using the above technical solution, the amplitude of the jumping table can be adjusted by connecting the threaded head to the inside of different adjustment holes.

[0014] Furthermore, the jump bar is slidably connected inside the sleeve.

[0015] The above technical solution allows for vibration testing of the vaulting table by sliding the vaulting bar inside the sleeve.

[0016] Furthermore, the sliding block is slidably connected to the outside of the slide rod.

[0017] The above technical solution allows the scraper to move on the top of the jumping table by sliding the sliding block outside the slide bar.

[0018] Furthermore, the turntable is rotatably connected to the upper part of the base.

[0019] With the above technical solution, the rotation of the turntable on the upper part of the base can drive the support rod fixed on the turntable to rotate. The support rod drives the jumping bar to move up and down inside the sleeve through the drive frame, thereby causing the jumping table to vibrate up and down.

[0020] Furthermore, the scraper is slidably connected to the upper part of the folding table.

[0021] Using the above technical solution, the scraper can slide on the top of the table to scrape the cement mortar remaining on the table into the filter box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation between the base, motor, sleeve, support rod, jumping table, conical mold, drive frame and adjustment hole, the vibration test of cement mortar can be achieved. The amplitude of the jumping table can be adjusted by threading the threaded head into the inside of different adjustment holes.

[0024] 2. In this utility model, through the cooperation of structures such as cylinder, L-shaped rod, jumping table, sliding block, fixed plate, scraper, filter screen and collection box, the cement mortar remaining on the jumping table can be scraped off and cleaned, preventing the mortar from accumulating during cleaning and improving the accuracy of cement mortar flowability measurement.
