The fixing mechanism 4 includes a motor 41, a supporting plate 42, a support frame 49 and a wear-resistant plate 410. The top of the supporting plate 42 is rotatably connected with a gear ring 43. Four groups of gears 44 are meshed inside the gear ring 43. Racks 45 are meshed on the outer walls of the four groups of gears 44. Support rods 46 are fixedly installed at the bottom of the four groups of racks 45. Moving plates 47 are fixedly installed on the tops of the four groups of racks 45. Rubber pads 48 are fixedly installed on one side of the four groups of moving plates 47. The top of the motor 41 is connected to the bottom of the support frame 49 for sliding, the output end of the motor 41 is connected to the bottom of a group of gears 44 for transmission, the tops of the four groups of gears 44 are connected to the bottom of the support frame 49 for rotation, the clamping arm 6 is installed inside the two groups of connecting blocks 7, the bottom of the supporting plate 42 is fixedly connected to the top of the fork frame 3, the top of the motor 41 is fixedly connected to the bottom of the supporting plate 42, the four groups of moving plates 47 are respectively arranged at the four corners of the supporting plate 42, the four groups of moving plates 47 are arranged around the support frame 49, the bottom of the wear-resistant plate 410 is fixedly connected to the top of the support frame 49, the four groups of moving plates 47 are arranged below the wear-resistant plate 410, and the bottom of the support frame 49 is fixedly connected to the top of the supporting plate 42.

[0025] The specific settings and functions of this embodiment are described in detail below. When it is necessary to unload the green bricks, the forklift 1 is driven to the edge of the brick pile, the adjustment mechanism 5 is started, and the clamping arm 6 is driven to clamp the stacked green bricks. At the same time, the fork frame 3 of the forklift 1 is started, so that the fork frame 3 drives the supporting plate 42 to move to the height of unloading bricks, and the clamping arm 6 moves the stacked green bricks to the top of the wear-resistant plate 410. At this time, the motor 41 is started to drive a group of gears 44 to rotate, and then the gear 44 drives the ring gear 43 to rotate on the top of the supporting plate 42. Therefore, the ring gear 43 simultaneously drives the other three groups of gears 44 to rotate, so that the four groups of gears 44 rotate synchronously, and the top of the gear 44 does not contact the bottom of the moving plate 47. The four groups of gears 44 drive the four groups of racks 45 to slide at the bottom of the support frame 49. The rack 45 drives four groups of support rods 46 to slide on the top of the supporting plate 42, and the rack 45 drives four groups of movable plates 47 to move. The four groups of movable plates 47 approach the center position synchronously until multiple groups of rubber pads 48 contact the side walls of the blue bricks and apply a slight pressure to make the blue bricks stacked neatly and compactly. Then the forklift 1 is started to unload and move the blue bricks away. By setting a fixing mechanism 4 and using the supporting plate 42 to support the bottom of the blue bricks, the bricks can be supported more evenly, reducing the possibility of damage to the bricks, protecting the integrity of the bricks, and reducing work interruptions caused by shaking or instability. The four groups of movable plates 47 are used to fix and limit the blue bricks to ensure that the blue bricks remain in a neat shape during the unloading and transportation process, and to avoid the blue bricks falling due to bumps or machine jams during movement.

The inner wall of the threaded sleeve 56 is threadedly connected to the outer wall of the screw rod 54.

[0028] The effect achieved by the entire embodiment is that the forklift 1 is driven to one side of the brick pile, at which time the clamping arm 6 is in an open state, and the electric cylinder 52 is started to drive the mobile frame 51 to slide up and down on one side of the door frame 2, so that the mobile frame 51 moves to a suitable height, and then the motor 2 53 is started to drive the screw 54 to rotate, and then the threaded sleeve 56 moves horizontally inside the mobile frame 51, and at the same time drives the moving seat 55, the connecting block 7 and the clamping arm 6 to move to the side of the stacked blue bricks, and then the two sides of the clamping arm 6 gradually approach and contact the side wall of the lowest blue brick, and apply pressure to clamp and lift the piled blue bricks, and at the same time the fork frame 3 drives the moving plate 47 to move in the vertical direction, so that the clamping arm 6 horizontally transports the blue bricks to Above the wear-resistant plate 410, the four groups of movable plates 47 are in an open state, the movable frame 51 drives the blue bricks to move downward, and the fork frame 3 drives the wear-resistant plate 410 to move upward until the bottom of the blue brick contacts the top of the wear-resistant plate 410, and the clamping arm 6 reduces the pressure on the blue brick, but is still on both sides of the blue brick. The forklift 1 transfers the blue brick. By setting an adjustment mechanism 5, the blue bricks of different stacking heights can be integrated, clamped and unloaded, and in conjunction with the fixing mechanism 4, the stress time of the side wall of the blue brick at the bottom is shortened, and the stacked blue bricks can be transferred to the top of the wear-resistant plate 410 at a faster speed, avoiding damage or falling caused by the stress on the side wall of the blue brick, which is convenient for unloading and transferring the blue bricks.

At this time, start the motor 41 to drive a set of gears 44 to rotate, and then the gear 44 drives the ring gear 43 to rotate on the top of the supporting plate 42. Therefore, the ring gear 43 drives the other three sets of gears 44 to rotate at the same time, so that the four sets of gears 44 rotate simultaneously. The top of the gear 44 does not contact the bottom of the moving plate 47, and the four groups of gears 44 drive the four groups of racks 45 to slide at the bottom of the support frame 49. The racks 45 drive the four groups of support rods 46 to slide on the top of the supporting plate 42, and the racks 45 drive the four groups of moving plates 47 to move. The four groups of moving plates 47 move toward the center synchronously until the multiple groups of rubber pads 48 contact the side walls of the blue bricks and apply a slight pressure to make the blue bricks stacked neatly and compactly, and then start the forklift 1 to unload and move the blue bricks away.
