Spring one end is fixedly connected on the working tips of full-automatic reisilometer, and the other end is connected with weight；The gear of motor is half tooth
Wheel construction, the bottom side of the weight is set to the broached-tooth design being engaged with motor gear, bottom side and the motor tooth of weight
Wheel part with teeth is meshed；Graduated scale is set in parallel in above centre pilot, is recovered spring and is run through setting on the scale, and one
End is fixed on the scale, other end concatenation pointer.
Preferably, a kind of described full-automatic reisilometer for being used to test concrete crushing strength, its feature exists
In：Also include set screw, the one end for recovering spring is connected on the scale by set screw, for being adjusted by changing
The position of section screw is corrected to instrument.
A kind of described full-automatic reisilometer for being used to test concrete crushing strength, it is characterised in that：Also include main frame,
Data for recording measurement.
A kind of described full-automatic reisilometer for being used to test concrete crushing strength, it is characterised in that：Also include being used for
Control the switch of electric motor operation and the battery of power supply is provided.
A kind of described full-automatic reisilometer for being used to test concrete crushing strength, it is characterised in that：Also include rotation

Preferably, a kind of described full-automatic reisilometer for being used to test concrete crushing strength, its feature exists
In：The full-automatic reisilometer whole installation is gun stock formula structure.
Beneficial effect：The present invention provide it is a kind of be used to test the full-automatic reisilometer of concrete crushing strength, with electronic
Machine driving spring and weight, weight hit the elastic stem with concrete surface perpendicular contact with constant kinetic energy, make local coagulation
Soil deforms and absorbs part energy, and another part energy is converted into the bounce-back kinetic energy of weight, when bounce-back kinetic energy all turns
When being melted into potential energy, weight bounce-back reaches ultimate range, and instrument shows the maximum rebound distance of weight with the name of rebound value
Come；Motor driving spring is used, and an extension spring is only installed, the energy consumption of motor, and the construction behaviour of its gun stock formula is reduced
It is more convenient, it is time saving and energy saving.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is scale portion schematic diagram in the present invention；
In figure：Elastic stem 1, rotary handle 2, motor 3, switch 4, battery 5, centre pilot 6, graduated scale 7, main frame 8, refer to
Pin 9, recovery spring 10, set screw 11, weight 12, extension spring 13.
Embodiment
The present invention is further described with reference to specific embodiment.
As shown in figure 1, a kind of full-automatic reisilometer for being used to test concrete crushing strength, including elastic stem 1, rotation hand
Handle 2, motor 3, switch 4, battery 5, centre pilot 6, graduated scale 7, main frame 8, pointer 9, recover spring 10, set screw 11,
Weight 12, extension spring 13;Wherein, elastic stem 1 and weight 12 are sequentially sleeved on centre pilot 6, and can be along centre pilot 6
Slidably reciprocate, wherein, elastic stem 1 is arranged on the working tips of full-automatic reisilometer；The one end of extension spring 13 is fixedly connected on entirely
The working tips of automatic rebounding instrument, the other end is connected with weight 12；The gear of motor 3 is half gear structure, the weight 12
Bottom side is set to the broached-tooth design being engaged with motor gear, and the part that the bottom side of weight 12 is with teeth with motor gear is mutually nibbled
Close；Graduated scale 7 is set in parallel in the top of centre pilot 6, recovers spring 10 through setting on the scale 7, one end is fixed on tune
Save on screw 11, other end concatenation pointer 9, and pass through the data of 8 record pointer of main frame 9.Also include being used to control electric motor operation
Switch 4 and provide power supply battery 5.Rotary handle 2, rotary handle is axially vertical with centre pilot, and can be led around center
Bar is rotated, and user can be adjusted handle to suitable position according to the custom of oneself, it is operated more and is facilitated.Entirely certainly
Part in dynamic reisilometer is arranged in the housing of the construction of gun stock formula.
Main frame is similar to the digital-display resiliometer host function principle applied in the market, and processing data can be recorded automatically.
Weight 12 uses gear drive with motor 3, and motor gear is half gear structure, and motor 3 is arrived with moving gear extension spring
After certain distance, weight sawtooth portion departs from motor gear and hits elastic stem 1 under the effect of extension spring 13.Recover spring 10
7 on through graduated scale（As shown in Figure 2）, one end concatenation pointer 9, the other end is fixed in set screw 11, by changing tune
The position of section screw 11 is corrected to instrument.
The specific implementation process of the present invention is as follows：
The first step, the regulation of device：
Adjusting nut 11 is opened, by moving left and right the position of adjusting nut so as to adjust the elasticity of recovery spring 10, is entered
And the reading of adjusting means, comply with standard；
Second step, starts measurement：
Make reisilometer working end perpendicular contact to component surface to be measured, press switch 4, motor 3 drives weight 11, makes weight
Hammer is stretched to motor gear after certain distance along centre pilot 6 and is out of gear with weight, and extension spring 13 pulls weight to hit
Elastic stem 1, makes local concrete deform and absorbs part energy, the bounce-back that another part energy is converted into weight is moved
Can, weight bounce-back drives pointer 9 to reach ultimate range, and the record data of main frame 8 finally recovers spring 10 and pulls pointer to return pointer
To initial position, measurement terminates.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
