Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed Reason, concrete block crush values easy to use hit detection device, it is using the impact hammer of Mechanical Driven to concrete block side wall Percussion repeatedly is carried out, the hardness of concrete is judged with raw sample mass percent by the quality after tapping, is applicable in From the test experience of the flintiness of different concrete formulations.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes hemispherical shield, anti-down branch Frame, support base, fixed slot, fixed support rectangular frame, rotating platform, driving gear, driven gear, connecting rod, shock Pendulum, concrete block;A circle falling-proof bracket is connected on the outside of the hemispherical shield, the bottom of hemispherical shield is set It is equipped with support base, the centre of support base is provided with fixed slot, and the fixed slot upper end is plugged with fixed support square Shape frame, and concrete block limit is connected among support base upper end by fixed support rectangular frame;The fixed support The upper end of rectangular frame is connected with rotating platform, and driving gear, driving gear and clamping are provided among the upper end of rotating platform Driven gear in rotating platform side is intermeshed;And connecting rod is connected on the outside of driven gear, the top rotation of connecting rod It is connected to shock pendulum.
Preferably, the outside of the shock pendulum is provided with the thread groove that is screwed on, and rotation inside the thread groove that is screwed on It is connected to convex clump weight.
Preferably, the driving gear and driving motor is coaxially connected, and drive the outside half sliding tooth of gear Item, generally smooth cambered surface.
Preferably, the upper end of the hemispherical shield is flushed with rotating platform holding.
After adopting the above structure, the utility model has the beneficial effect that concrete block crush values described in the utility model are hit Detection device is hit, it carries out percussion repeatedly to concrete block side wall using the impact hammer of Mechanical Driven, passes through the matter after tapping Amount judges the hardness of concrete with raw sample mass percent, is applicable in and the detection of the flintiness of different concrete formulations The advantages that experiment, the utility model have structure simple, and setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Description of symbols:
Hemispherical shield 1, falling-proof bracket 2, support base 3, fixed slot 4, fixed support rectangular frame 5, rotary flat Platform 6, driven gear 8, connecting rod 9, hits pendulum 10, concrete block 11 at driving gear 7.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to as Figure 1-Figure 4, present embodiment adopt the following technical scheme that it include hemispherical shield 1, Falling-proof bracket 2, support base 3, fixed slot 4, fixed support rectangular frame 5, rotating platform 6, driving gear 7, driven gear 8, connecting rod 9, shock pendulum 10, concrete block 11;The outside of the hemispherical shield 1 is connected with a circle falling-proof bracket 2, the bottom of hemispherical shield 1 is provided with support base 3, and the centre of support base 3 is provided with fixed slot 4, and described consolidates Determine 4 upper end of slot and be plugged with fixed support rectangular frame 5, and the limit of concrete block 11 is connected to by fixed support rectangular frame 5 Among 3 upper end of support base;The upper end of the described fixed support rectangular frame 5 is connected with rotating platform 6, rotating platform 6 it is upper End is intermediate to be provided with driving gear 7, and driving gear 7 is intermeshed with the driven gear 8 for being connected to 6 side of rotating platform;And from The outside of moving gear 8 is connected with connecting rod 9, and the top of connecting rod 9, which is screwed with, hits pendulum 10.
