Detailed Implementation

[0026] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] Its structure includes a testing box 1, a controller 2, and an equipment box 3. The testing box 1 is integrally and rigidly connected to the inside of the equipment box 3. The surface of the equipment box 3 is bolted to the bottom of the controller 2. The left end of the controller 2 is clearance-fitted to the inside of the testing box 1. The testing box 1 includes an experimental barrel 11, a hinged cylinder 12, a sealing cover 13, and a partition groove 14. The outer side of the experimental barrel 11 is integrally clearance-fitted to the hinged cylinder 12. Both ends of the hinged cylinder 12 are hinged to the bottom of the sealing cover 13. The inner surface of the sealing cover 13 is movablely fitted to the surface of the experimental barrel 11. The right end of the experimental barrel 11 is integrally clearance-fitted to the partition groove 14.

[0030] The experimental barrel 11 includes a barrel wall 111, a mixer 112, and an auxiliary turntable 113. The interior of the barrel wall 111 is nested with the mixer 112. The lower end of the mixer 112 is nested with the center of the auxiliary turntable 113. The surface of the auxiliary turntable 113 is welded to the lower end of the barrel wall 111. The mixer 112 is distributed inside the barrel wall 111 and is nested with the interior of the barrel wall 111. Its bottom is nested with the center of the auxiliary turntable 113. The auxiliary turntable 113 helps to assist the mixer 112 in rotating, thereby mixing the added concrete and test reagents to obtain test results.

[0031] The mixer 112 includes a scraper a1, a mixing chamber a2, a drive rod a3, and a mixing table a4. The center of the scraper a1 is nested with the drive rod a3, the middle of the drive rod a3 is engaged with the inner wall of the mixing table a4, the surface of the mixing table a4 is movable with the interior of the mixing chamber a2, the outer end of the mixing chamber a2 is movable with the surface of the scraper a1, the scraper a1 is distributed at the outer end of the drive rod a3, the center is nested with the surface of the drive rod a3, and the inner side is in a clearance fit with the mixing table a4. The scraper a1 is driven to rotate under the drive rod a3, thereby scraping the concrete thrown onto the inner wall of the bucket and preventing the concrete from sticking to the bucket wall.

[0032] The scraping frame a1 includes a through-hole groove a11, a stabilizing frame a12, a scraping plate a13, and a swing bar a14. The through-hole groove a11 is integrally fixedly connected to the center of the stabilizing frame a12. The lower end of the stabilizing frame a12 is hingedly connected to the top end of the swing bar a14. The surface of the swing bar a14 is fixedly connected to the inner wall of the scraping plate a13. The two ends of the scraping plate a13 are clearance-fitted with the inner side of the stabilizing frame a12. There are four sets of scraping plates a13, distributed on the surface of the swing bar a14 and fixedly connected to the surface of the swing bar a14. The two sides are clearance-fitted with the stabilizing frame a12. The swing bar a14 facilitates the swinging of the scraping plate a13 during rotation. When encountering hardened concrete, it will swing hingedly, changing the angle of the scraping plate a13, thereby removing the concrete.

[0033] The specific working principle is as follows:

[0034] This invention opens the sealing cover 13 through the hinged cylinder 12, exposing the test box 1 to the outside. With the cooperation of the controller 2 and the equipment box 3, concrete is added inside the test bucket 11. Then, the corresponding test reagent is added to the test bucket 11 through the partition groove 14. With the cooperation of the auxiliary turntable 113 and the mixer 112, the reagent is fully mixed in the mixing chamber a2 inside the bucket wall 111. The drive rod a3 then rotates the scraper a1 and the stirring table a4. The stabilizing frame a12 nested in the through-hole groove a11, under the action of rotation, drives the swing bar a14 and the scraper a13 to slap the mixture against the bucket wall 11. The concrete is scraped, and when it solidifies, the swing bar a14 moves to change the angle of the scraper a13. The angle is changed, and then the concrete is further removed. The present invention drives the scraper a1 to rotate with the cooperation of the internal motor through the rear drive rod a3 to scrape the concrete mixed with the test reagent. This avoids the concrete sticking and solidifying on the barrel wall during the scraping process. At the same time, the scraping angle of the scraper a13 can be changed by the movement of the swing bar a14, thereby removing the concrete on the barrel wall 111. This effectively solves the problem of the barrel wall of the test device being difficult to clean and easy to leave residue. Example 2

[0035] As attached Figure 6 To be continued Figure 9 As shown:

[0036] The mixing table a4 includes a movable mixing plate a41, an anti-detachment ring a42, and a protective cylinder a43. The movable mixing plate a41 is nested inside the protective cylinder a43. The center of the protective cylinder a43 is welded to the inner wall of the anti-detachment ring a42. The anti-detachment ring a42 is nested to the center of the movable mixing plate a41. The movable mixing plate a41 is distributed and nested inside the protective cylinder a43, and its center is nested to the center of the anti-detachment ring a42. The anti-detachment ring a42 helps to assist the movable mixing plate a41 in its movement, thereby changing the orientation of the movable mixing plate a41 and ensuring that the concrete inside is fully mixed with the anti-corrosion testing reagent.

[0037] The movable stirring plate a41 includes a swinging stirring bar b1, a slide b2, a tension spring b3, and a rolling bar b4. The end of the swinging stirring bar b1 is fixed to the inside of the slide b2 with bolts. The outer wall of the slide b2 is embedded and connected to the top of the tension spring b3. The inner wall of the slide b2 is integrally engaged with the rolling bar b4. There are two slides b2, with their bottoms integrally engaged with their rolling bars b4, and their interiors fixed to the end of the swinging stirring bar b1 with bolts. The slides b2 facilitate swinging with the gap between the inner wall of the inner ring with the tension spring b3 and the rolling bar b4, thereby providing the swinging stirring bar b1 with spacing and movement distance.

[0038] The swing agitator b1 includes an extension bar b11, a sleeve bolt b12, and a connecting rod b13. The end of the extension bar b11 is hinged to the inside of the sleeve bolt b12. The left wall of the sleeve bolt b12 is welded to the top of the connecting rod b13. The right end of the connecting rod b13 is in clearance fit with the extension bar b11. There are three extension bars b11 in total, which overlap when triggered, and their ends are staggered and nested inside the sleeve bolt b12. The extension bars b11 help to accelerate the agitation and mixing of concrete and test reagents, thereby increasing the mixing area, reducing the mixing time, and improving the testing efficiency.

[0039] The extension strip b11 includes an impact ball c1, a ball-locking groove c2, a strip body c3, and a nesting pin c4. The impact ball c1 is fully engaged with the ball-locking groove c2, and the impact ball c1 is nested within the strip body c3. The end of the strip body c3 is nested within the nesting pin c4, and the outer end of the nesting pin c4 is loosely fitted with the impact ball c1. The impact ball c1 is distributed inside the strip body c3 and nested within it. Its surface is engaged with the ball-locking groove c2. The impact ball c1 facilitates the unfolding of the strip body c3 with the help of the nesting pin. After unfolding, the centrifugal inertia causes the impact ball c1 to be thrown out and strike the concrete gel block, delaying the setting of the concrete and extending the reaction time with the test reagent.

[0040] The specific working principle is as follows:

[0041] This invention utilizes a drive rod a3 engaged with an anti-detachment ring a42 for meshing connection. During rotation, the movable stirring disc a41 inside the protective cylinder a43, driven by rotational force, causes the slide table b2 to swing left and right under the cooperation of the spring spring b3 and the rolling bar b4. This provides spacing and movement distance for the swinging stirring bar b1. Upon reaching a certain rotational speed, the sleeve bolt b12 at the front end of the connecting rod b13 spreads out the diffuser bar b11. The overlapping diffuser bars b11, under the hinged engagement of the nested pin c4, unfold the bar body c3, allowing it to contact... The striking ball c1 is thrown out from the ball-holding groove c2 to strike the concrete gel block, delaying the setting of the concrete and extending the reaction time with the test reagent. This invention uses the swinging stirring bar b1 and the movable stirring plate a41 to swing left and right in conjunction with the sliding table b2 and the rolling bar b4, thereby providing the spacing and movement distance for the swinging stirring bar b1. At the same time, under the action of centrifugal force, it cooperates with the sleeve bolt b12 to divide the diffuser bar b11 into three, which accelerates the stirring and mixing of concrete and test reagent, effectively expands the mixing area, reduces the mixing time, and indirectly improves the testing efficiency.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention; no reference numerals in the claims should be construed as limiting the scope of the claims.
