Description

Technical Field

[0001] The utility model relates to the technical field of mortar detection equipment, and specifically to a detection equipment for acceptance of mortar. Background Art

[0002] The mortar consistency meter is an instrument used to measure the fluidity of mortar. Generally, fluidity is also called consistency. The consistency of mortar is expressed by the number of centimeters of the depth of a standard cone of a certain geometric shape and weight that sinks freely into the mortar mixture with its own weight. With the continuous development of science and technology, the mortar consistency meter is constantly being improved in structure and function, and it is believed that it will be more widely used in the future.

[0003] At present, when the existing mortar consistency meter is tested, the test cone is generally lifted manually and then released to make the test cone automatically drop, or the connecting rod is fixed by bolts after lifting, and then the bolts are twisted to release the fixing of the connecting rod to make the test cone automatically drop. The automation level is low, and inaccurate detection may occur due to touching the device during manual operation.

[0004] The application number is 202320224870.1, and the patent name is a testing device for accepting mortar. It cooperates with a fixed frame, connecting rod, test cone, top plate, screw, fixed plate, support plate, first mounting plate, and first motor to make the test cone automatically drop into the mortar in the mortar barrel to detect the mortar consistency. It has a high degree of automation and does not require manual touching of the device during detection, thus avoiding inaccurate detection due to touching the device during manual operation.

[0005] However, there are still some shortcomings: the height at which the test cone automatically descends is fixed, and the height at which the test cone descends cannot be adjusted for the same mortar. The experimental data is single and not accurate enough. Utility Model Content

[0006] The utility model aims at the deficiencies of the prior art and provides a testing device for acceptance of mortar, which effectively solves the problems in the prior art that the height of the automatic descent of the test cone is fixed, the descent height of the test cone cannot be adjusted for the same mortar, and the test data is single and not accurate enough.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is:

[0008] A testing device for accepting mortar comprises a material storage box, on which a height adjustment structure is provided, and the height adjustment structure is drivingly connected to a support plate, a through hole is opened in the middle of the support plate, a limit bracket is provided at the upper end of the through hole, fixed blocks are provided at both sides of the upper end of the limit bracket, an electromagnet is provided at the lower end of the fixed block, a test cone corresponding to the through hole is provided on the inner side of the limit bracket, sliding shaft blocks slidably connected to the inner wall of the limit bracket are provided at both sides of the upper end of the test cone, and an iron sheet corresponding to the electromagnet is provided at the upper end of the sliding shaft block.

[0009] The height adjustment structure includes a motor fixedly connected to one side of the material storage box, the output end of the motor is fixedly connected to a screw rod, the two ends of the support plate are respectively provided with a first support shaft and a second support shaft, the inner wall of the second support shaft is fixedly connected to a screw barrel threadedly connected to the screw rod, and the inner wall of the first support shaft is slidably connected to a limiting sliding rod fixedly connected to the other side of the material storage box.

[0010] The limit sliding rod is provided with scale lines.

[0011] A discharge pipe is arranged at the bottom of the material storage box, and a closing valve is arranged on the discharge pipe.

[0012] The diameter of the through hole is larger than the diameter of the test cone.

[0013] The utility model has novel structure, ingenious design, simple and convenient operation, and has the following advantages compared with the prior art:

[0014] 1. The utility model controls the vertical up and down movement of the support plate, thereby indirectly adjusting the height of the test cone, and obtains multiple sets of detection data by changing the falling height of the test cone, thereby improving the accuracy of the detection.

[0015] 2. After the electromagnet is powered off, the iron sheet on the sliding block and the electromagnet are disconnected. Under the influence of gravity, the test cone slides down, and the sliding block limits the movement of the test cone to ensure that the test cone falls vertically. The test cone falls into the mortar in the storage box. Since the test cone is provided with a scale, the consistency of the mortar can be tested. There is no need to manually touch the device during the test, thus avoiding inaccurate detection due to touching the device during manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0022] like Figure 1-4 As shown, a testing device for acceptance of mortar includes a storage box 1, on which a height adjustment structure is provided, and the height adjustment structure is driven and connected to a support plate 7, a through hole 18 is opened in the middle of the support plate 7, a limit bracket 8 is provided at the upper end of the through hole 18, and fixed blocks 9 are respectively provided on both sides of the upper end of the limit bracket 8, and an electromagnet 10 is provided at the lower end of the fixed block 9, and an experimental cone 13 corresponding to the through hole 18 is provided on the inner side of the limit bracket 8, and sliding shaft blocks 11 slidably connected to the inner wall of the limit bracket 8 are respectively provided on both sides of the upper end of the experimental cone 13, and an iron sheet 12 corresponding to the electromagnet 10 is provided at the upper end of the sliding shaft block 11.

[0023] When the test cone 13 is used, the mortar to be inspected is added into the material storage box 1. When the electromagnet 10 is energized, the electromagnet 10 and the iron sheet on the sliding shaft block 11 are adsorbed to fix the position of the sliding shaft block 11. When the test cone 13 is used to detect the mortar, after the electromagnet 10 is powered off, the iron sheet 12 on the sliding shaft block 11 and the electromagnet 10 are disconnected. Under the influence of gravity, the test cone 13 slides down, and the sliding shaft block 11 limits the movement of the test cone 13 to ensure that the test cone 13 falls vertically. The test cone 13 falls into the mortar in the material storage box 1. Since a scale is provided on the test cone 13, the consistency of the mortar can be detected. There is no need to manually touch the device during detection, which avoids the situation that inaccurate detection occurs due to the touch device during manual operation. The height adjustment structure is controlled to work, and the falling height of the test cone 13 is indirectly adjusted by controlling the support plate 7 to move up. By changing the falling height of the test cone 13, multiple groups of detection data are obtained, thereby improving the accuracy of detection.

[0024] The height adjustment structure includes a motor 16 fixedly connected to one side of the storage box 1, and the output end of the motor 16 is fixedly connected to a screw 15. The two ends of the support plate 7 are respectively provided with a first support shaft 6 and a second support shaft 17. The inner wall of the second support shaft 17 is fixedly connected to a screw barrel 14 threadedly connected to the screw 15, and the inner wall of the first support shaft 6 is slidably connected to a limiting slide rod 4 fixedly connected to the other side of the storage box 1.

[0025] like Figure 1-3 As shown, the motor 16 is working, and the output end of the motor 16 drives the screw 15 to rotate. During the rotation of the screw 15, it cooperates with the screw barrel 14 on the inner wall of the second support shaft 17, thereby driving the support plate 7 to move up and down. During the up and down movement of the support plate 7, the first support shaft 6 can move up and down along the limiting slide bar 4, and the limiting slide bar 4 is used to limit the movement of the support plate 7 to ensure that the support plate 7 moves vertically up and down, thereby indirectly adjusting the height of the experimental cone 13.

[0026] The limit sliding rod 4 is provided with scale lines 5 .

[0027] like Figure 1 As shown, the scale line 5 on the limit slide bar 4 can be used to mark the height to which the test cone 13 falls.

[0028] A discharge pipe 2 is disposed at the bottom of the storage box 1 , and a closing valve 3 is disposed on the discharge pipe 2 .

[0029] like Figure 1 As shown, after the mortar in the storage box 1 is tested, the closing valve 3 can be opened to discharge the mortar in the storage box 1 for next use.

[0030] The diameter of the through hole 18 is larger than the diameter of the test cone 13 .

[0031] like Figure 1 and 3 As shown, it is ensured that the test cone 13 can move down normally.

[0032] The working process of the utility model is as follows: when the utility model is in use, the mortar to be inspected is added into the storage box 1, and when the electromagnet 10 is energized, the electromagnet 10 and the iron sheet on the sliding block 11 are adsorbed to fix the position of the sliding block 11. When the test cone 13 is used to test the mortar, the electromagnet 10 is powered off, and the iron sheet 12 on the sliding block 11 and the electromagnet 10 are disconnected. Under the influence of gravity, the test cone 13 slides down, and the sliding block 11 limits the movement of the test cone 13 to ensure that the test cone 13 falls vertically. The test cone 13 falls into the mortar in the storage box 1. Since the test cone 13 is provided with a scale, the consistency of the mortar can be tested. There is no need to manually touch the device during the test, which avoids inaccurate detection due to the touching device during manual operation.

[0033] The motor 16 is working, and the output end of the motor 16 drives the screw 15 to rotate. During the rotation of the screw 15, it cooperates with the screw barrel 14 on the inner wall of the second support shaft 17, thereby driving the support plate 7 to move up and down. During the up and down movement of the support plate 7, the first support shaft 6 can move up and down along the limiting slide bar 4, and the limiting slide bar 4 is used to limit the movement of the support plate 7 to ensure that the support plate 7 moves vertically up and down, thereby indirectly adjusting the height of the experimental cone 13. By changing the falling height of the experimental cone 13, multiple sets of detection data can be obtained, thereby improving the accuracy of the detection.

[0034] After the mortar in the storage box 1 is tested, the closing valve 3 can be opened to discharge the mortar in the storage box 1 for next use.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
