Abstract
Description
Technical Field
[0001] This utility model relates to the field of bentonite strength testing technology, and specifically to a bentonite strength testing device. Background Technology
[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. It is widely used due to its characteristics such as low permeability, high expansion and high adsorption.
[0003] Before using bentonite in large quantities, various indicators of bentonite need to be tested, including the strength test. However, during the bentonite sampling and testing process, bentonite of different hardness needs to be tested. Only bentonite that meets the qualified strength can proceed to the next indicator test. Therefore, the bentonite is tested after processing. However, testing each type of bentonite with different strengths individually wastes a lot of overall production time. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bentonite strength testing device. This device solves the technical problem that, during the bentonite sampling and testing process, it is necessary to test bentonite of different hardness levels before proceeding to the next stage of index testing. Therefore, all bentonite samples are tested after processing, which results in a significant waste of overall production time due to the need to test each type of bentonite with different strengths individually.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bentonite strength testing device includes a workbench with a support frame on the workbench and a support platform on one side of the support frame. A first motor is mounted on the support platform, and a first rotating shaft is horizontally mounted on the output end of the first motor. The first rotating shaft rotates through the support frame. A first thread and a second thread are respectively provided on the outer wall of the first rotating shaft, and the first thread and the second thread are in opposite directions. Two movable platforms are screwed onto the first rotating shaft, and the two movable platforms are respectively screwed to the first thread and the second thread. A guide block is integrally connected to the rear side of the two movable platforms. A horizontal sliding groove is provided on the support frame, and the two guide blocks are slidably mounted on the sliding groove. A pressing component is mounted on each of the two movable platforms, and the pressing component faces the workbench. A stabilizing component for fixing the bentonite is provided on the workbench.
[0007] Working principle:
[0008] When testing the strength of bentonite, the operator first places bentonite of different strengths on the workbench. Then, the operator starts the first motor, which drives the first rotating shaft to rotate. The first rotating shaft drives the moving platform to rotate, and the moving platform drives the guide block to move. The guide block drives the pressing component to move until the pressing component moves above the bentonite to be tested. Then, the operator starts the stabilizing component to stabilize the bentonite placed on the workbench. Next, the operator starts the pressing component. At this point, the two pressing components press the two pieces of bentonite stabilized on the stabilizing component to obtain different strengths, allowing for a simultaneous comparison of the different strengths of the two pieces of bentonite.
[0009] The beneficial effects of this utility model are as follows:
[0010] The first motor drives the first rotating shaft to rotate, which in turn drives the moving platform to rotate. The moving platform then moves the guide block, which in turn moves the pressing components. The two pressing components can simultaneously test bentonite of different strengths. The operator then only needs to compare the ultimate pressure that bentonite of different strengths can withstand under the same given pressure. The stabilizing components not only fix the bentonite to be tested, but also allow the remaining bentonite debris to be cleaned off the workbench after the ultimate strength test is completed.

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1As shown, a bentonite strength testing device includes a workbench 1, a support 2 on the workbench 1, and a support platform 3 on one side of the support 2. A first motor 5 is mounted on the support platform 3. A first rotating shaft 4 is horizontally mounted on the output end of the first motor 5 and rotatably passes through the support 2. A first thread 6 and a second thread 7 are respectively provided on the outer wall of the first rotating shaft 4, with the first thread 6 and the second thread 7 in opposite directions. Two movable platforms 8 are screwed onto the first rotating shaft 4, and the two movable platforms 8 are respectively screwed to the first thread 6 and the second thread 7. A [missing information - likely a device name] is integrally connected to the rear side of the two movable platforms 8. The guide block 9 is provided with a horizontal slide groove 10 on the bracket 2. Both guide blocks 9 are slidably installed on the slide groove 10. Each of the two moving platforms 8 is provided with a pressing assembly. The pressing assembly includes two hydraulic cylinders 11 and two pressure gauges 12. The two hydraulic cylinders 11 are fixedly installed on the two moving platforms 8, and the telescopic ends of the two hydraulic cylinders 11 pass vertically downward through the moving platform 8. The two pressure gauges 12 are fixedly installed on the telescopic ends of the two hydraulic cylinders 11, and face vertically downward toward the worktable 1. The pressing assembly faces the worktable 1. The worktable 1 is provided with a stabilizing assembly for fixing bentonite.
[0015] When it is necessary to test the strength of bentonite, firstly, the operator places bentonite of different strengths on the workbench 1. Then, the operator starts the first motor 5, which drives the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the moving platform 8 to rotate, and the moving platform 8 drives the guide block 9 to move. The guide block 9 drives the pressing component to move until the pressing component moves above the bentonite to be tested. Then, the operator starts the stabilizing component to stabilize the bentonite placed on the workbench 1. Then, the operator starts the pressing component. At this time, the two pressing components press the two pieces of bentonite stabilized on the stabilizing component to obtain different strengths, and the different strengths of the two pieces of bentonite can be compared at the same time.
[0016] The first motor 5 drives the first rotating shaft 4 to rotate, which in turn drives the moving platform 8 to rotate. The moving platform 8 then moves the guide block 9, which in turn moves the pressing components. These two pressing components can simultaneously test bentonite of different strengths. The operator then only needs to compare the ultimate pressure that bentonite of different strengths can withstand under the same given pressure. The stabilizing components not only fix the bentonite to be tested but also allow for the removal of any remaining bentonite debris from the workbench 1 after the ultimate strength test is completed. Figure 1As shown, the stabilizing assembly includes two cylinders 16, two L-shaped pressing blocks 17, and a T-shaped stabilizing block 18. The two cylinders 16 are respectively horizontally fixed at both ends of the workbench 1, and the two cylinders 16 face each other. The telescopic ends of the two cylinders 16 pass through the bracket 2. The two pressing blocks 17 are respectively fixedly installed at the telescopic ends of the two cylinders 16, and the two pressing blocks 17 face each other. The stabilizing block 18 is fixedly installed in the middle of the workbench 1 and located between the two pressing blocks 17. It also includes two first shovel plates 19 and two second shovel plates 20, wherein the two first shovel plates 19 are respectively fixedly installed at the... Located at the bottom of two extrusion blocks 17, two second shovel plates 20 are fixedly installed on both sides of the stabilizing block 18, and the two second shovel plates 20 are respectively opposite to the two first shovel plates 19. The two first shovel plates 19 and the two second shovel plates 20 are close to the surface of the workbench 1. The workbench 1 is provided with four long strip-shaped through grooves 21. The four long strip-shaped through grooves 21 are arranged in pairs, and each pair of long strip-shaped through grooves 21 is located on both sides of the stabilizing block 18. It also includes a chip collection cylinder 22 with an opening at the top. The chip collection cylinder 22 is fixedly installed at the bottom of the workbench 1, and its opening faces the four long strip-shaped through grooves 21.
[0017] The two cylinders 16 can drive the two extrusion blocks 17 to move. Then, the extrusion blocks 17 move and extrude to both sides of the stabilizing block 18. In this way, the bentonite blocks on the workbench 1 can be gathered and stabilized, and the strength of the bentonite can be measured more easily. The shovel plate can also be used to clean the bentonite residue and debris after testing, and better clean the bentonite residue and debris into the long groove 21, and finally collect it into the chip collection cylinder 22.
