[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0029] like Figure 1-6 As shown, a device for measuring the compressive strength of a concrete block comprises:

[0030] The bottom plate 1 has an arc-shaped bracket 12 symmetrically arranged on the bottom plate 1, a slide groove 121 is provided in the arc-shaped bracket 12, and a support plate 4 is slidably arranged in the slide groove 121;

[0031] The support frame 3 is arranged on the bottom plate 1, and the support frame 3 is provided with a cylinder 2, and the output end of the cylinder 2 is clamped with a pressure plate 32 facing the support plate 4;

[0032] Transmission unit 5, which is disposed on base plate 1, includes a rack 52, a support block 51, and a motor disposed on support block 51, a first gear 53 on the motor output shaft, the first gear 53 meshing with the rack 52, and the support block 51 cooperating with base plate 1;

[0033] The rack 52 is provided with a rotating rod 42 that cooperates with the supporting plate 4 , and the first gear 53 rotates to control the rack 52 to push the supporting plate 4 on the arc-shaped bracket 12 to generate an inclination.

[0034] Specifically, during the operation of the motor, the rack 52 is linked to slide on the base plate 1 through the first gear 53, so that the support plate 4 is pushed to slide in the slide groove 121 through the rotating rod 42. When sliding to the tail end of the slide groove 121, the support plate 4 rotates relative to the rotating rod 42 under the action of gravity, so that the support plate 4 is tilted and fits with the arc-shaped bracket 12, and the concrete debris on the support plate 4 is tilted and poured into the lower hopper 11. During the flipping process, the first gear 53 is in an idling state and does not contact the rack 52. After the first gear 53 is reversed, it will re-engage the tooth groove of the rack 52. The motor model is: MHMF042L1U2M2.

[0035] As an embodiment further provided by the present invention, a second gear 54 is rotatably provided on the support block 51 and meshed with the first gear 53. A turntable 55 is symmetrically provided on the second gear 54. A swing arm 56 is provided on the turntable 55. A slider 58 that touches the pressure plate 32 is provided on the swing arm 56. A lower hopper 11 is provided on the bottom plate 1, and the slider 58 slides on the lower hopper 11. Since the swing arm 56 is located at the eccentric position of the turntable 55 and there are two turntables 55, the swing arm 56 on one side is located at the eccentric position below the turntable 55, and the swing arm 56 on the other side is located at the eccentric position above the turntable 55. During the rotation of the second gear 54, the turntable 55 also rotates on the support block 51, so that the two swing arms 56 reciprocate and drive the two sliders 58 to slide intermittently, that is, intermittently touch the support plate 4, thereby increasing the contact frequency between the slider 58 and the support plate 4.

[0036] As an embodiment further provided by the present invention, a touch head 59 is provided at one end of the slider 58, and the touch head 59 is a rubber head. When the slider 58 slides back and forth on the lower hopper 11, the rubber head continuously hits the support plate 4, further improving the cleaning effect of the debris on the support plate 4.

[0037] As an embodiment further provided by the present invention, an inclined portion 110 is provided on the lower hopper 11, and the inclined portion 110 is in contact with the arc-shaped bracket 12. When the debris on the pallet 4 falls, the debris will slide along the inclined portion 110 into the lower hopper 11 and flow out of the lower hopper 11, thereby reducing the noise generated by the collision between the debris and the lower hopper 11.

[0038] As an embodiment further provided by the present invention, the support plate 4 is symmetrically provided with rubber rods 41 that are engaged with the base plate 1. When the support plate 4 contacts the base plate 1, the rubber rods 41 are used to, on the one hand, have a buffering effect to reduce the collision between the support plate 4 and the base plate 1, and on the other hand, to support the support plate 4. A part of the rubber rods 41 will be stuck in the base plate 1 to limit the movement of the support plate 4.

[0039] As an embodiment further provided by the present invention, the support frame 3 includes a first support plate 33 and a second support plate 36. The second support plate 36 is symmetrically arranged on the base plate 1, and the first support plate 33 is fixed on the two second support plates 36 to support the cylinder 2. The support frame 3 consists of a horizontally placed first support plate 33 and two vertically placed second support plates 36, and the cylinder 2 is located at the axis center of the first support plate 33 for output.

[0040] As a further embodiment provided by the present invention, a tripod 34 is symmetrically arranged between the first support plate 33 and the second support plate 36. The tripod 34 is used to support the first support plate 33 and the second support plate 36, thereby improving the stability of the support frame 3 and reducing the shaking generated during measurement.

[0041] As an embodiment further provided by the present invention, a pressure tester 37 is connected to the output end of the cylinder 2, and the pressure tester 37 cooperates with the pressure plate 32. When the compressive strength of the concrete block is measured, the pressure value is obtained by the pressure tester 37 and recorded. After obtaining the test data of multiple concrete blocks, a comparison is performed to improve the accuracy of the experimental data.

[0042] As an embodiment further provided by the present invention, a guide block 35 is symmetrically arranged on the pressure plate 32 and cooperates with the second support plate 36. A sliding groove 121 is provided on the second support plate 36, and the guide block 35 is located in the sliding groove 121. The guide block 35 supports the pressure plate 32 and guides the pressure plate 32 to slide upward or downward along the axis.

[0043] As an embodiment further provided by the present invention, a fixing hole 31 is provided on the support frame 3, and a protective cover 30 is provided on the support frame 3 to engage with the fixing hole 31. The protective cover 30 is made of a transparent material. When the static compressive strength of the concrete block is measured, the protective cover 30 is engaged with the fixing hole 31 to provide a protective function during the measurement to prevent the bump from collapsing.

[0044] Working principle: extract multiple concrete blocks, place one of them on the support plate 4, make the protective cover 30 fit with the fixing hole 31, and then operate the cylinder 2 to make the pressure plate 32 slide along the support frame 3 until it contacts the concrete block, and perform a compressive strength test on it, record the value detected by the pressure tester 37, and then the motor runs, and drives the rack 52 to slide on the bottom plate 1 through the first gear 53, and pushes the support plate 4 to slide on the arc bracket 12 through the rack 52. When it slides to the end of the slide groove 121, the rotating rod 42 causes the support plate 4 to tilt on the arc bracket 12, and the tested concrete The soil fragments slide from the support plate 4 to the lower hopper 11 and are discharged from the lower hopper 11. At the same time, the first gear 53 drives the second gear 54 to rotate, that is, the turntable 55 rotates, thereby driving the swing rod 56 to push the slider 58 to slide back and forth on the lower hopper 11, so that the contact head 59 knocks on the tilted tray, causing it to shake, further improving the cleaning effect of the concrete fragments. After cleaning, the rack 52 will pull the support plate 4 to slide to the bottom of the pressure plate 32, and then the compressive strength of the next concrete block will be measured. The automated method improves the testing efficiency of the concrete blocks and the accuracy of the experimental test values.

[0045] The technical solution of the above-mentioned utility model provides a solution that is significantly different from the existing technology to address the technical problem that the existing technology solution is too single. The parts not involved in the technical solution of this application are the same as the existing technology or can be implemented by using the existing technology, and will not be repeated here.

[0046] The technical solutions in the above embodiments have clearly and completely described the contents of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
