Technical Field

[0001] The utility model relates to the technical field of concrete products, and particularly relates to a concrete test block crushing device. Background Art

[0002] After the detection of the concrete test block is completed, it is necessary to crush the concrete test block for the purpose of recycling the crushed concrete test block. The crusher is the device for crushing the concrete test block. When it is necessary to crush the concrete test block, generally, the staff directly pours the concrete test block into the feed hopper of the crusher, and then the crusher crushes the concrete test block. However, a large amount of dust and relatively loud noise will be generated during the crushing process of the above device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a concrete test block crushing device to solve the problems put forward in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a concrete test block crushing device, including a workbench and support beams straddling both sides of the workbench; an electric heater and a blanking hole are provided on the workbench, and a receiving container is provided directly below the blanking hole; a hydraulic jack is provided on the support beam, and the provided pressing plate is urged by the hydraulic jack to move into the receiving container to crush the test block entering the receiving container.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0017] Please refer to Figures 1 - 3, an embodiment provided by the present utility model: a concrete test block crushing device, including a workbench 1 and support beams 7 straddling both sides of the workbench 1; an electric heater 12 and a blanking hole 6 are provided on the workbench 1, and a receiving container 11 is provided directly below the blanking hole 6; a hydraulic jack 8 is provided on the support beam 7, and a pressing plate 5 provided is urged by the hydraulic jack 8 to move into the receiving container 11 to crush the test block that enters the receiving container 11.

[0018] In summary, when the test block is placed on the workbench 1, the electric heater 12 is used to cover the outside of the test block and heat the test block; after the heating is completed, the test block is moved into the receiving container 11. At this time, the hydraulic jack 8 is used to urge the pressing plate 5 to move downward to crush the test block that enters the inside of the receiving container 11. Since the pressing plate 5 can cover the opening of the receiving container 11 during the process of moving into the inside of the receiving container 11, blocking the splashing of dust, and at the same time, the slow descent of the hydraulic jack 8 can also reduce the splashing of dust.

[0019] Based on this, while the device realizes the crushing of the test block, the cooperation of the receiving container and the pressing plate can reduce the problem of a large amount of dust caused by the exposure of the test block, and the noise generated during the crushing of the test block is also reduced.

[0020] Furthermore, since a connecting pipe 3 is provided on the upper end surface of the electric heater 12, and a guide rod 14 is provided on the connecting pipe 3, and the guide rod 14 slides along a guide seat 16 provided on the workbench 1, therefore, the connecting pipe 3 can be used to introduce the wire into the electric heater 12, and at the same time, the guide rod 14 slides in the guide seat 16, which can also guide the electric heater 12 to move up and down smoothly, thereby facilitating the electric heater 12 to cover the outside of the test block; specifically, the cross-section of the guide rod 14 is preferably rectangular, so that the problem of axial rotation of the electric heater 12 during the up and down movement can be avoided.

[0021] Even further, since an electric push rod 13 is also provided on the guide seat 16, and the guide rod 14 is urged by the electric push rod 13 to slide in the guide seat 16, therefore, the electric push rod 13 can be used to complete the automatic lifting of the electric heater 12. Among them, the electric push rods 13 are all purchased on the market. For example, the model of the electric push rod 13 is: LX401, a 24V electric push rod; in addition, the electric heater 12 can also be purchased on the market. Its general structure is as follows: it has a housing, which is connected to the connecting pipe 3, and then electric heaters or electric heating sheets are uniformly arranged on the inner wall surface of the housing.

[0022] In addition, since a heat insulation pad 4 is also laid on the workbench 1 and the heat insulation pad 4 is located below the electric heater 12, the heat insulation pad 4 can be used to prevent heat dissipation and the burn caused by heat to the surface of the workbench 1.

[0023] On the basis of the above solution, since a support seat 10 for carrying the receiving container 11 is further provided on the workbench 1 and a limiting projection 9 is provided on the support seat 10, when the receiving container 11 is pushed into the workbench 1 until it contacts the limiting projection 9, the movement of the receiving container 11 can be stopped, thereby ensuring that the opening of the receiving container 11 can be aligned with the blanking hole 6, so that the test block can smoothly fall into the receiving container 11; wherein, the limiting projection 9 is semi-circular in shape and the inner diameter is equal to the outer diameter of the receiving container 11.

[0024] In addition, since a hydraulic pump station 15 is further provided on the support seat 10, on the one hand, it provides power for the hydraulic jack 8; on the other hand, integrating it on the support seat 10 can make full use of the space of the workbench 1.

[0025] At the same time, since a control box 2 is further provided on the workbench 1, it is convenient for the user to use the control buttons on the control box 2 to realize the lifting, heating of the electric heater 12 and the lifting of the hydraulic jack 8.

[0026] In summary, compared with the crushing equipment in the prior art, such as the prior art with the publication numbers of: CN209791618U and CN112474011A, this equipment can use the cooperation of the pressing plate 5 and the receiving container 11 to reduce the exposed space of the test block during the crushing process; at the same time, during the crushing process of the test block, since it is crushed by extrusion, the noise is small and the dust is small.

[0027] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
