The guard plate 7 is an L-shaped plate that matches the corners of the pallet 3, and the counterweight 8 is fixed at The outer surface of the guard plate 7 is located at the corner of the guard plate 7, and the weight of the outer side of the guard plate 7 is increased by the counterweight block 8; the limit rod 9 is fixed on one side of the opening of the installation groove 4, and the two sides of the limit rod 9 are fixed to the side walls of the support plate 2. The limit rod 9 is used to limit the flipping angle of the positioning member. When there is no object pressing on the surface of the movable plate 6, the guard plate 7 is flipped toward the outer side of the support plate 2 by the weight of the counterweight block 8. After the guard plate 7 is flipped to a certain angle, the range of movement is limited by the limit rod 9, and after the guard plate 7 is flipped outward, the support plate 2 Each group of guard plates 7 protruding from the surface of the plate 2 forms an outwardly opened funnel shape, which enlarges the space when the pallet 3 enters the top of the support plate 2, which is conducive to the placement of the pallet 3. When the pallet 3 is pressed on the surface of the movable plate 6, the movable plate 6 moves toward the bottom of the support plate 2. When the movable plate 6 is flush with the support plate 2, the inner corner of the guard plate 7 is aligned with the corner of the pallet 3, so that the guard plate 7 limits the various sides of the pallet 3, avoiding the pallet 3 from shaking significantly during the stacking of brick blanks, thereby reducing the possibility of the brick blanks tilting and collapsing.

[0025] A hydraulic cylinder 10 is fixed at the bottom center of the support plate 2. The height of the support plate 2 is controlled by the hydraulic cylinder 10.

A turntable 11 is fixed at the bottom of the hydraulic cylinder 10. The turntable 11 can drive the support plate 2 to rotate through the hydraulic cylinder 10, thereby driving the pallet 3 to turn. During the process of stacking bricks, each layer of bricks needs to be staggered and stacked to improve the stability of the brick stacking. When staggered stacking is performed, the pallet 3 can be turned by the turntable 11, so that the conveyor belt 1 can enter the bricks on the surface of the pallet 3. Under the condition that the angle is not changed, overlapping stacking can still be achieved on the surface of the pallet 3. A fixed plate 12 is fixed at the bottom of the turntable 11. A bottom plate 13 is provided below the fixed plate 12, mounting plates are fixed at both ends of the bottom plate 13, a screw rod 14 is provided between the two sets of mounting plates, guide rods are provided on both sides of the screw rod 14, nut seats are sleeved on the surfaces of the screw rod 14 and the guide rods, the top of the nut seat is fixed to the fixed plate 12, a motor 15 is fixed to one end of the screw rod 14, the motor 15 drives the screw rod 14 to rotate, so that the nut seat sleeved on the outer ring of the screw rod 14 moves, and the nut seat drives the fixed plate 12 and each set of accessories above the fixed plate 12 to move together, when stacking brick blanks, the conveyor belt 1 transports the brick blanks to the surface of the pallet 3 through the guide roller, and the motor 15 controls the distance of the pallet 3 close to the conveyor belt 1, so that the brick blanks transported by the conveyor belt 1 can be arranged regularly, which is beneficial to the stability of the brick blank stacking.

[0026] Working principle: the motor 15 is arranged at the bottom of one side of the discharge port of the conveyor belt 1. When the bricks are stacked, the pallet 3 is placed on the surface of the support plate 2 by means of an instrument or manually. When the pallet 3 is placed, the bottom of the pallet 3 presses the movable plate 6, so that the movable plate 6 drives the guard plate 7 to rotate, so that the guard plate 7 is vertically arranged on the side of the pallet 3, and the corners of the pallet 3 are limited to prevent the pallet 3 from deflecting and shaking during stacking. The height of the surface of the pallet 3 is controlled by the hydraulic cylinder 10, so that the pallet 3 is close to the bottom of the guide roller of the conveyor belt 1, and the conveyor belt 1 can directly transport the bricks to On the surface of the tray 3, the distance between the bottom plate 13 and the conveyor belt 1 is controlled by the motor 15, so that the tray 3 can arrange the bricks in order when receiving them. When the bricks are stacked higher, the tray 3 can be turned by the turntable 11, so that the layers of the bricks are staggered and stacked, which is beneficial to the stability of the brick stacking. When the bricks on the surface of the tray 3 are stacked to a certain number, the tray 3 is lifted from the surface of the support plate 2 by machinery. When the tray 3 moves up, the positioning piece is rotated outward again by the gravity of the counterweight block 8, so that the top of the guard plate 7 is opened outward, which is beneficial to the placement of the subsequent tray 3.
