Description

Technical Field

[0001] The utility model belongs to the technical field of cement density testing, in particular to a cement and admixture density testing device. Background Art

[0002] When conducting density tests on cement and admixtures, the test tool commonly used is a Leah flask, also known as a density bottle. It has a capacity of 220-250 ml and a narrow neck approximately 18-20 cm long and 1 cm in diameter. The neck is graduated from 0 ml to 24 ml, with 0.1 ml marks between 0-1 ml and 18-24 ml.

[0003] When adding cement and admixtures to a Leclerc flask, the existing cement and admixture density test device cannot accurately grasp the amount of cement and admixtures entering the Leclerc flask because the cement and admixtures are viscous. Cement and admixtures need to be added slowly, which is inefficient. Utility Model Content

[0004] The present invention aims to solve the problems in the prior art and proposes the following technical solutions:

[0005] The cement and admixture density testing device includes a constant temperature box and a Levin flask body placed inside the constant temperature box. A feeding box is arranged above the Levin flask body. The outer wall of the feeding box is fixedly connected to a fixing frame, and the fixing frame is fixedly connected to the constant temperature box. The inner wall of the feeding box is rotatably connected to a feeding roller, and a cleaning component fixedly connected to the feeding box is arranged below the feeding roller.

[0006] As a preferred embodiment of the above technical solution, the feed roller is provided with a plurality of feed grooves.

[0007] As a preferred embodiment of the above technical solution, one side of the feed roller is fixedly connected to a rotating shaft, and the end of the rotating shaft away from the feed roller passes through the feed box to drive one side and is fixedly connected to a rotating handle.

[0008] As a preferred embodiment of the above technical solution, the cleaning component includes a fixed support plate fixed on the inner wall of the feed box, and the fixed support plate is fixedly connected to a guide slide rod on the side close to the feed roller. The outer ring movable sleeve of the guide slide rod is provided with a scraper, and the scraper is in contact with the feed trough.

[0009] As a preferred embodiment of the above technical solution, two symmetrically arranged material guide plates are fixedly connected to the side of the scraper away from the feed roller.

[0010] As a preferred embodiment of the above technical solution, the fixed support plate is fixedly connected to an elastic member, and one end of the elastic member away from the fixed support plate is fixedly connected to the scraper.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model drives the feed roller to rotate by rotating the rotary handle. The cement and admixture located above the feed roller will enter the interior of the feed trough, and then be quantitatively fed from top to bottom into the interior of the Lehr flask body. While the feed roller is rotating, the scraper will scrape off the cement and admixture attached to the feed roller and the outer wall of the feed trough, and shake the cement and admixture into the interior of the Lehr flask body through its own shaking, which not only accurately feeds the materials but also improves the experimental efficiency.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example 1

[0020] like Figure 1 and Figure 2 As shown, the cement and admixture density testing device includes a constant temperature box 1 and a Levin flask body 2 placed inside the constant temperature box 1, a feeding box 4 is arranged above the Levin flask body 2, the outer wall of the feeding box 4 is fixedly connected to a fixing frame 3, the fixing frame 3 is fixedly connected to the constant temperature box 1, the inner wall of the feeding box 4 is rotatably connected to a feeding roller 5, and a cleaning component fixedly connected to the feeding box 4 is arranged below the feeding roller 5, and the feeding roller 5 is provided with a plurality of feeding troughs 51, and the feeding troughs 51 are arranged in a circular array with the center of the feeding roller 5.

[0021] It should be noted that the feed roller 5 divides the feed box 4 into two parts. The part above the feed roller 5 is the material storage area, and the part below the feed roller 5 is the material discharge area.

[0022] like Figure 2As shown, one side of the feed roller 5 is fixedly connected to a rotating shaft 6, which is located at the center of the feed roller 5. The end of the rotating shaft 6 away from the feed roller 5 passes through the feed box 4 to drive one side, and is fixedly connected to a rotating handle 7, which is located at the center of the rotating shaft 6.

[0023] Specifically, rotating the rotating handle 7 can drive the rotating shaft 6 connected to it to rotate together, and the rotation of the rotating shaft 6 will drive the feeding roller 5 to rotate. At this time, the cement and admixture located in the storage area above the feeding roller 5 will fall into the inside of the feeding trough 51. Through the rotation of the feeding roller 5, the materials are quantitatively fed from top to bottom into the interior of the Lethenium flask body 2, thereby improving the feeding accuracy.

[0024] Example 2

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the cement and admixture density testing device, compared with Example 1, the cleaning component of this embodiment includes a fixed support plate 8 fixed on the inner wall of the feed box 4, the fixed support plate 8, and a guide slide 9 is fixedly connected to the side close to the feed roller 5. The outer ring of the guide slide 9 is movably sleeved with a scraper 10. There are at least two guide slides 9, which are used to increase the stability of the scraper 10 so that the scraper 10 does not shake when moving. The scraper 10 conflicts with the feed trough 51, and the side of the scraper 10 away from the feed roller 5 is fixedly connected to two symmetrically arranged guide plates 11. The scraper 10 and the guide plate 11 are in a "Y" shape. The fixed support plate 8 is fixedly connected to an elastic member 12, which is a spring and is sleeved on the outer ring of the guide slide 9. The end of the elastic member 12 away from the fixed support plate 8 is fixedly connected to the scraper 10.

[0026] Specifically, the elastic member 12 will push the scraper 10 away from the fixed support plate 8. When the feed roller 5 rotates, the scraper 10 will move along the outer wall of the feed roller 5 and the feed trough 51, and scrape off the cement and admixtures attached to the outer wall of the feed roller 5 and the feed trough 51. The rotation of the feed roller 5 will cause the scraper 10 and the guide plate 11 to shake up and down continuously through the cooperation of the elastic member 12, so that the cement and admixtures on the outer wall of the feed roller 5 and the feed trough 51 will not adhere to the scraper 10 and the guide plate 11 during the falling process. At the same time, the scraper 10 and the guide plate 11 are in a "Y" shape, and the fallen cement and admixtures will not adhere to the fixed support plate 8, the guide slide bar 9 and the elastic member 12.

[0027] Working principle: Turning the rotary handle 7 can drive the rotating shaft 6 connected to it to rotate together. The rotation of the rotating shaft 6 will drive the feeding roller 5 to rotate. At this time, the cement and admixture in the storage area above the feeding roller 5 will fall into the inside of the feeding trough 51. Through the gear shift of the feeding roller 5, the cement and admixture are quantitatively fed from top to bottom into the interior of the Lethen flask body 2. When the feeding roller 5 rotates, the scraper 10 will move along the outer wall of the feeding roller 5 and the feeding trough 51, and the cement attached to the outer wall of the feeding roller 5 and the feeding trough 51 will be removed. The rotation of the feeding roller 5 will cause the scraper 10 and the guide plate 11 to shake up and down continuously through the cooperation of the elastic member 12, so that the cement and admixtures on the outer wall of the feeding roller 5 and the feeding trough 51 will not adhere to the scraper 10 and the guide plate 11 during the falling process. At the same time, the scraper 10 and the guide plate 11 are in a "Y" shape, and the fallen cement and admixtures will not adhere to the fixed support plate 8, the guide slide rod 9 and the elastic member 12, which can improve the experimental efficiency while feeding accurately.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
