The four separation oil cylinders 35 are equally divided into two groups and symmetrically arranged on a pair of long sides of the surrounding frame 32 and are respectively vertically opposite to the four lugs 34.4 on the rectangular groove 34.2 one by one; As Figure 3As shown in the figure, the four separating oil cylinders 35 are all installed in the following manner: The separating oil cylinders 35 are vertically placed inside the bottom-opening clamping cavity 32.1. A first flange 35.1 is provided on the outer periphery of the cylinder body. The first flange 35.1 is fixed to the inner top wall of the bottom-opening clamping cavity 32.1 by screws to fix the separating oil cylinder 35 to the surrounding frame 32. The piston rod of the separating oil cylinder 35 passes upward through the first rod hole provided on the top surface of the bottom-opening clamping cavity 32.4 and is exposed. A top block 35.2 for jacking the corresponding lug 34.4 is provided on the rod head. The top block 35.2 and the lug 34.4 are vertically aligned and spaced apart. The top block 35.2 can be set as a cylinder with an inner hole on the bottom surface. The top block 35.2 is sleeved on the top end of the piston rod of the separating oil cylinder 35 through its inner hole and fixed by screws.

The supporting plate 31 is fixedly installed on the top of the base 20 to support the entire stone slab ramming system 30 by the base 20.

[0029] There are four lifting oil cylinders 33. The four separating oil cylinders 33 are equally divided into two groups and symmetrically arranged on a pair of long sides of the surrounding frame 32; as Figure 4As shown, the four lifting cylinders 33 are all installed in the following manner: the lifting cylinder 33 is inserted into the installation hole provided on the supporting plate 31 from the bottom of the supporting plate 31, and the outer periphery of the cylinder body is provided with a second flange 33.1, and the second flange 33.1 is screwed to the bottom surface of the supporting plate 31, so as to fix the lifting cylinder 33 upright on the supporting plate 31, and make the upper half of the cylinder body of the lifting cylinder 33 built into the bottom opening clamping cavity 32.1; the piston rod of the lifting cylinder 33 passes upward through the second rod hole provided on the top surface of the bottom opening clamping cavity 32.1, and then The upper part of the surrounding frame 32 which is exposed to avoid the lug 34.4 is sleeved with an inner locking block 33.2 and an outer locking block 33.3 on the rod head. The inner locking block 33.2 is arranged in the bottom opening clamping cavity 32.1 and is screwed to the inner top wall of the bottom opening clamping cavity 32.1. The outer locking block 33.3 is fixed to the piston rod of the lifting cylinder 33 from the upper part of the surrounding frame 32, and cooperates with the inner locking block 33.2 to lock and fix the piston rod of the lifting cylinder 33 to the top of the bottom opening clamping cavity 32.1, so as to lift and connect the surrounding frame 32 to the supporting plate 31. The advantage of this installation method is that the lifting cylinder 33 can be disassembled and assembled from the lower part of the supporting plate 31, and there is no need to lift the surrounding frame 32 and the pressure head assembly 34 during disassembly and assembly, so as to facilitate quick disassembly and assembly. For this purpose, an operating space is required between the base 10, the base 20 and the supporting plate 31 to allow the lifting cylinder 33 to be loaded or pulled out from the lower part of the supporting plate 31.

The transmission roller group 42 lifts the bottom of the transmission belt 41 from the bottom so that the bottom of the transmission belt 41 also passes between the frame 32 and the supporting plate 31.

[0032] During operation, the surrounding frame 32 and the press head assembly 34 are in the high position to open the transfer channel. The preformed quartz stone slab is conveyed by the conveyor belt 41 to the lower part of the surrounding frame 32 and the press head assembly 34. Then, the surrounding frame 32 can be driven by the lifting oil cylinder 33 to slowly press on the supporting plate 31 and the conveyor belt 41. The press head assembly 34 is driven by the separating oil cylinder 35 to move downward and press on the bottom of the surrounding frame 32. The quartz stone slab is tamped and formed by the action of the vibration device 34.3. Then, the press head assembly 34 can be driven by the separating oil cylinder 35 to disengage from the bottom of the surrounding frame 32. The surrounding frame 32 is driven by the lifting oil cylinder 33 to lift and open the transfer channel. The formed quartz stone slab is taken away from the compaction system 30 by the conveyor belt 41.

[0033] If it is necessary to replace and maintain the lifting oil cylinder 33, the outer lock block 33.3 can be removed first, and then the fixing screws of the second flange 33.1 can be unscrewed, and the lifting oil cylinder 33 can be taken out from under the supporting plate 31. If it is necessary to replace and maintain the separating oil cylinder 35, the surrounding frame 32 can be lifted by the lifting oil cylinder 33 first, then the top block 35.2 can be removed, and then the fixing screws of the first flange 35.1 can be unscrewed, and the separating oil cylinder 35 can be taken out from under the surrounding frame 32.
