Wherein, the fixed frame 16 is horizontally arranged on the first frame 11, and the area of the inner ring of the fixed frame 16 is larger than that of the brick pile, thereby facilitating the fixed frame 16 to be sleeved on the brick pile. In order to separate the brick layers from each other from top to bottom by the brick supporting device 14 and the folding device 15, the distance between the fixed frame 16 and the bearing platform 12 needs to be adjusted, and as a preferred embodiment of the invention, the bearing platform 12 is fixed, and the fixed frame 16 moves up and down along the first machine frame 11, so that the height of the fixed frame 16 sleeved on the brick pile is adjusted.

The folding device 15 and the brick supporting device 14 are arranged up and down on the fixed frame 16, so that the brick supporting device 14 corresponds to a lower layer brick, and the folding device 15 corresponds to an upper layer brick.

As a preferred embodiment of the present invention, the tile-supporting device 14 comprises a first clamping plate 141, a first clamping cylinder 142, a second clamping plate 143, and a second clamping cylinder 144, wherein,

a first clamping plate 141 provided inside a set of opposite sides of the fixing frame 16;

a second clamping plate 143 disposed inside the other pair of opposite sides of the fixing frame 16;

and a second clamping cylinder 144, which is arranged outside the fixed frame 16 and is used for driving the second clamping plate 143 to translate.

From this setting, when the fragment of brick terminal surface of lower floor's brick just is first clamp plate 141, the fragment of brick side of lower floor's brick just is second clamp plate 143, and at this moment, first clamp cylinder 142 drive first clamp plate 141 translation, and two sets of first clamp plates 141 are the translation relatively, carry out the centre gripping to fragment of brick both ends face simultaneously, eliminate the clearance between the fragment of brick terminal surface, and then realize that the fragment of brick presss from both sides tightly each other in length direction. At this time, the second clamping plate 143 is driven by the second clamping cylinder 144 to slightly translate, and only the lateral side of the outermost brick of the lower brick is supported without performing translation and extrusion, so as to prevent the upper brick from toppling over without the support of the lower brick after the bricks are closed. According to the different initial brick pile placing forms, the end face of the brick of the lower layer brick is opposite to the second clamping plate 143, and the side face of the corresponding brick of the lower layer brick is opposite to the first clamping plate 141.

In the embodiment of the present invention, the push plate 150 is enclosed around the upper layer brick, specifically, the push plate 150 includes a first plate 1501 and a second plate 1502, the first plate 1501 is disposed inside one set of opposite sides of the fixing frame 16, the second plate 1502 is disposed inside the other set of opposite sides of the fixing frame 16, the first plate 1501 is located right above the first clamping plate 141, and the second plate 1502 is located right above the second clamping plate 143;

On the basis of the above embodiment, after the lower layer brick is clamped by the first clamping plate 141 and the second clamping plate 143, the lower layer brick is kept in a static state on the horizontal plane, at this time, the first plate 1501 corresponds to the side face of the upper layer brick, the second plate 1502 corresponds to the end face of the upper layer brick, the first pushing cylinder 1511 drives the first plate 1501 to translate, the second pushing cylinder 1512 drives the second plate 1502 to translate, because the opposite faces of the first plate 1501 and the second plate 1502 are arranged in an inclined shape, the upper portions of the first plate 1501 and the second plate 1502 are firstly contacted with the upper portions of the bricks, that is, the first plate 1501 is contacted with the upper portions of the side faces of the bricks, and the second plate is contacted with the upper portions of the end faces, when the bricks are pushed, the upper layer brick and the lower layer brick can be easily separated by using the lever principle, thereby avoiding the defect or bonding problem between the bricks caused by the horizontal friction shear separation of the upper layer brick and the lower layer brick 1502, the surface quality of the shale bricks after being stacked is improved. During the relative translation of the two groups of first plates 1501 and the relative translation of the two groups of second plates 1502, the upper layer of bricks can be folded and reshaped inwards.

In order to make the first plate 1501 and the second plate 1502 can be fine separation upper brick and lower floor's brick in the translation in-process, and do not take place the brick and empty, the scheme that this embodiment adopted is: the distance from the top surface of the first plate 1501 to the inner side surface of the fixed frame 16 is larger than the distance from the bottom surface of the first plate 1501 to the inner side surface of the fixed frame 16; the distance from the top surface of the second plate 1502 to the inside surface of the fixed frame 16 is greater than the distance from the bottom surface of the second plate 1502 to the inside surface of the fixed frame 16; the first plate 1501 and the second plate 1502 are both inclined at an angle of 1 ° to 20 °. Adopt above-mentioned technical scheme, first plate 1501 and second plate 1502 slope down, the angle so sets up, when easily realizing upper brick and lower floor's fragment of brick separation, can avoid the fragment of brick to empty again, guarantees that the upper brick folds whole buttress and goes on smoothly. Specifically, when the angle is too small, the contact area between the first plate 1501 and the second plate 1502 and the brick is large, the brick approaches to the horizontal pushing direction, the upper layer brick and the lower layer brick are in surface-to-surface contact at the moment, and are separated through mutual friction shearing, so that at least the separated brick is bonded or has surface defects. The angle is too large, and when the first plate 1501 and the second plate 1502 push the bricks in the upper layer, the bricks are easy to push, so that the bricks cannot be folded.

Because the brick supporting device 14 and the folding device 15 are arranged up and down inside the fixed frame 16, the brick layer is supported and stabilized or folded in a surrounding mode. Each brick separating mechanism can only perform the brick separating operation on one brick pile, thereby causing low efficiency.
