[0016] This invention provides a concrete slump testing device. Compared with the prior art, it has the following advantages:

[0017] (1) The concrete slump testing device, through the film winding mechanism, can be stably wound as a power drive. By inserting one end of the disposable film into the slot, after the test, the motor output drives the drive wheel, and the drive wheel drives the driven wheel on one side to rotate. At this time, the shaft and the winding rod rotate, and the winding rod winds the disposable film. After the test, the concrete piled on the disposable film moves to the connecting plate at the top of the winding rod and then falls through the connecting plate. After the concrete falls, the winding rod rolls up a portion of the used disposable film.

[0018] (2) The concrete slump testing device facilitates the replacement and delivery of the film through the film laying mechanism. The L-shaped groove has an "L" shaped opening, which makes it easy to quickly insert the connecting shaft. Push it in along the "L" shape and slide it longitudinally into the arc groove. The operation is simple and quick. The film surface is smooth and wrinkle-free, and can fit with the base to ensure that the concrete slumps tightly with the film. When the film is taken in by the film taking mechanism, the connecting shaft drives the plastic film roll to rotate. The connecting shaft contacts the roller, which reduces friction when rotating, making it easy to deliver the plastic film roll smoothly. Attached Figure Description

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

[0027] Example 1:

[0028] Please see Figure 1 A concrete slump testing device, comprising:

[0029] A base 1 has connecting frames 2 fixedly installed on both sides of the base 1. A lifting component 3 is provided on the upper end of the connecting frame 2. A slump cylinder 4 is fixedly installed on the bottom end of the lifting component 3. The slump cylinder 4 is located on the upper end of the base 1.

[0030] The film-laying mechanism 5 is located at one end of the base 1. The film-laying mechanism 5 facilitates the continuous laying of disposable plastic film on the surface of the base 1.

[0031] Film winding mechanism 6 is located at the other end of base 1. Film winding mechanism 6 is used to wind up the used disposable plastic film.

[0032] Measurement component 7 is located inside one side of the connecting frame 2.

[0033] In this embodiment, the film-laying mechanism 5 and the film-collecting mechanism 6 work together. Before testing, one end of a disposable plastic film is pulled from the film-laying mechanism 5 and laid on the surface of the base 1. Then, the film-collecting mechanism 6 fixes one end. At this time, the lifting component 3 places the slump cylinder 4 on the top of the laid base 1. Concrete is filled into the slump cylinder 4, leveled, and then the lifting component 3 lifts the slump cylinder 4. The measuring component 7 measures the highest point of the concrete after slumping. After measurement, the film-collecting mechanism 6 pulls the disposable plastic film. After the concrete falls through one end of the base 1, the used disposable plastic film is rolled up. A new disposable plastic film is then laid on the top of the base 1 for the next test.

[0034] Example 2:

[0035] Please see Figure 2 and Figure 5 This embodiment provides a technical solution based on embodiment one: the film laying mechanism 5 includes two support blocks 51, which are symmetrically fixedly installed on one side wall of the base 1. L-shaped grooves 9 are formed on the surface of the two support blocks 51. An arc-shaped groove 14 is formed at the bottom of one side of the L-shaped groove 9. An installation groove 15 is formed at the bottom of the arc-shaped groove 14. Several sets of rollers 54 are rotatably installed in the installation groove 15. A connecting shaft 52 is rotatably installed on both arc-shaped grooves 14. A plastic film roll 53 is fixedly installed at one end of the two connecting shafts 52 that are close to each other.

[0036] In this embodiment, the film-laying mechanism 5 facilitates film replacement and delivery. The L-shaped groove 9 has an "L"-shaped opening, which facilitates the quick insertion of the connecting shaft 52. It is pushed in along the "L" shape and slides longitudinally into the arc-shaped groove 14. The operation is simple and quick. The film surface is smooth and wrinkle-free, and can fit with the base 1 to ensure tight adhesion to the film when the concrete collapses. When the film is taken in by the film-taking mechanism 6, the connecting shaft 52 drives the plastic film roll 53 to rotate. The connecting shaft 52 contacts the roller 54, which reduces friction when rotating, making it easier to deliver the plastic film roll 53 smoothly.

[0037] Please see Figure 3 and Figure 6The film collecting mechanism 6 includes two fixing blocks 66, which are symmetrically fixedly installed on the two side walls of the other end of the base 1. Each fixing block 66 has a through hole 8 on its surface. A bearing 62 is installed in the through hole 8. A rotating shaft 61 is fixedly connected to the inner ring surface of the bearing 62. A winding rod 67 is fixedly installed at the end of the two rotating shafts 61 that is close to each other. The winding rod 67 has a "+" structure. A slot 68 is opened at one end of the winding rod 67. The slot 68 is used to insert one end of the disposable film for fixing. A motor 65 is fixedly installed on one side of one of the fixing blocks 66. A drive wheel 64 is fixedly installed at the output end of the motor 65. A driven wheel 63 is meshed on one side of the drive wheel 64. The driven wheel 63 is fixedly connected to one end of one of the rotating shafts 61 on the side close to the fixing block 66.

[0038] A connecting plate 10 is fixedly installed at one end of the base 1, and the connecting plate 10 is located at the top of the coil rod 67.

[0039] In this embodiment, the film winding mechanism 6 is a power-driven mechanism that can stably wind up the film. The film laying mechanism 5 pulls one end of the disposable plastic film and inserts one end of the disposable film into the slot 68. After testing, the used portion of the film located at the bottom of the collapse tower 4 needs to be moved and wound up. The motor 65 is started, and the output end of the motor 65 drives the drive wheel 64. The drive wheel 64 drives the driven wheel 63 meshing on one side to rotate. At this time, the rotating shaft 61 and the winding rod 67 rotate. The winding rod 67 winds the disposable film. After testing, the concrete accumulated on the disposable film moves to the connecting plate 10 at the top of the winding rod 67 and then falls through the connecting plate 10. After the concrete falls, the winding rod 67 rolls up a portion of the used disposable film. The winding rod 67 has a "+" structure. After too much disposable film is wound on the surface of the winding rod 67, it is easy to cut it open and remove it with a sharp tool.

[0040] Please see Figure 2 The top of the connecting frame 2 is symmetrically provided with a moving groove 11. The lifting component 3 includes two moving plates 31, which are slidably installed in the moving groove 11. A top plate 32 is fixedly installed on one end of the two moving plates 31 above the connecting frame 2. A cylinder 33 is provided below the top plate 32. The bottom end of the cylinder 33 is fixedly installed on the top wall of the connecting frame 2. The telescopic end of the cylinder 33 is fixedly connected to the bottom wall of the top plate 32. A connecting block 34 is fixedly installed on one end of the two moving plates 31 below the connecting frame 2. The two connecting blocks 34 are symmetrically fixedly installed on the outer wall of the slump cylinder 4 at their closest ends.

[0041] In this embodiment, the lifting component 3 can accurately lift the slump cylinder 4, avoiding the risk of tilting when lifted manually. After the slump cylinder 4 is filled with concrete and leveled, the cylinder 33 is activated, and the cylinder 33 lifts the top plate 32. At this time, the moving plate 31 moves upward in the moving groove 11. The two moving plates 31 drive the connecting block 34 and the slump cylinder 4 to move upward, which can realize the slump of concrete.

[0042] Please see Figure 4 The connecting frame 2 has an adjustment groove 12 on one side wall and sliding grooves 13 on both sides of the adjustment groove 12. The measuring component 7 includes a measuring rod 71, which is located in the adjustment groove 12. A pull block 73 is fixedly installed at the bottom of the measuring rod 71. Two rotating wheels 72 are rotatably installed on both sides of the upper end of the measuring rod 71. The two rotating wheels 72 are rotatably installed in the sliding grooves 13. A scale line 74 is provided on one side of the connecting frame 2, which is located on the side of the measuring rod 71.

[0043] In this embodiment, the measuring component 7 can conveniently measure the slump concrete. When the slump cylinder 4 is lifted, the pull block 73 is pulled to rotate the measuring rod 71. The measuring rod 71 is rotated to 90 degrees and then moved up and down in the slide groove 13 via the rotating wheel 72. When it reaches the highest point of the concrete, the other end of the measuring rod 71 corresponds to the scale line 74, and the reading can be taken intuitively.
