Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained shall fall within the protection scope of the present invention.
Embodiment
Referring to figs. 1 to Fig. 3, the present embodiment is related to solidified earth direct shear apparatus, including pedestal 1, slidably on pedestal 1 under
Box body 2 and the upper cartridge body 3 on lower box body 2 are provided with through-hole 31, and be provided on the lower box body 2 on the upper cartridge body 3
Slot 21, the through-hole 31 are connected with the slot 21；Rolling mechanism, the rolling are equipped between the pedestal 1 and lower box body 2
Motivation structure includes ball 41 and the limiting plate 42 being fixedly mounted on the pedestal 1, is provided on the limiting plate 42 for placing
The arc groove of ball 41 is stated, and the perforation through the limiting plate 42 is provided on the arc groove；The one of the ball 41
End is contacted with the pedestal 1, stretches out the perforation outside the other end；The diameter of the perforation is less than the diameter of ball 41.It is shearing
Measure when, first upper cartridge body 3 and pedestal 1 are fixed, the solidified earth after demoulding is then put into the through-hole 31 and slot again
In hole 21, in next step, the wheel shaft to be advanced using constant speed applies horizontal applied force on lower box body 2, makes lower box body 2 in ball 41
It leads downwardly with respect to 3 carry out level slip of upper cartridge body, so as to be sheared to solidified earth.In the process that ball 41 rotates, ball
41 can only be rotated in the original location under the constraint of limiting plate 42, will not be moved and be slided with lower box body 2, it is therefore prevented that rolling
What the both ends horizontal of pearl 41 from pedestal 1 came off happens, and since the diameter of perforation is less than the diameter of ball 41, further
So that ball 41 will not be deviate from from vertical direction, so as to ensure that the stability and reliability of the work of ball 41.
The bottom surface of the lower box body 2 is provided with groove 22, and the external part of the ball 41 is caught in the groove 22.In groove
Under 22 constraint, groove 22 and the cooperation of ball 41 cause lower box body 2 that can only be moved in a straight line along the direction of ball 41, prevent
Lower box body 2 deviates from pedestal 1.
As shown in figure 4, the lower box body 2 is equipped with the top plate 5 through the slot 21, and the both ends of the top plate 5 are stretched
Go out the two sides of the lower box body 2；Specifically, the top plate 5 includes the ejection section 51 being slidably mounted in the slot 21,
And one end two pressing sections 52 hinged with ejection section 51 both ends respectively, described in the other end of the pressing section 52 stretches out
Lower box body 2.After solidified earth is cut, by applying downward pressure to pressing section 52, pressing section 52 drive ejection section 51 to
Upper movement, you can rapidly the remaining solidified earth in lower box body 2 is ejected, greatly facilitates the cleaning inside lower box body 2.
The lower box body 2 includes outter box 23 and the inner box 24 being fixedly installed in inside outter box 23, the slot 21
On inner box 24, the upper cartridge body 3 is set on inner box 24, and the through-hole 31 is connected with the slot 21.It is described
The upper surface of inner box 24 and the upper end surface of the outter box 23 are in same level.
In order to which the water in through-hole 31 and slot 21 is enable to be discharged downwards from by Water permeable body, the institute on the top plate 5
State the Water permeable body 6 that is equipped with and can be slided along slot 21 in slot 21.
Completion is measured carrying out shearing to solidified earth, in order to facilitate the taking-up of upper cartridge body 3, the inner box 24 is equipped with handle
Inner box 24 by holding handle 7, rapidly can be detached dismounting by hand 7 with outter box 23.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
Novel interest field, therefore the equivalent variations made according to the utility model claims, still belong to what the utility model was covered
Range.
