DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 5 As shown, a brick stacker according to an embodiment of the present invention comprises a receiving frame 1, a driving assembly 11 is arranged at the top of the receiving frame 1, and the driving assembly 11 is used to adjust the position of the receiving frame 1; a pair of first hydraulic cylinders 12 are symmetrically arranged at both ends of the receiving frame 1, and a clamping plate 13 is arranged at the end of the output end of the first hydraulic cylinder 12;

[0035] A plurality of plug holes 2 are evenly provided at the top of the receiving frame 1, and an interception plate 21 is inserted inside the plug hole 2, and a first connecting frame 22 is provided at the top of the interception plate 21; a second hydraulic cylinder 23 is provided at the end of the first connecting frame 22 away from the interception plate 21; the housing of the second hydraulic cylinder 23 is fixed to the top of the receiving frame 1; a third hydraulic cylinder 3 is provided at the top of the receiving frame 1, and a connecting member 31 is provided at the output end of the third hydraulic cylinder 3; a linkage plate 32 is provided at the end of the connecting member 31 away from the third hydraulic cylinder 3, and a push plate 33 is provided at the bottom end of the linkage plate 32;

[0036] In the actual stacking operation of bricks, when a large number of bricks are clamped and transferred at one time, the clamping structure needs to apply sufficient squeezing force to the outermost bricks to ensure that the clamping is firm; however, a large clamping force is easy to cause damage to the bricks, so it is necessary to optimize the clamping structure to ensure that the bricks are protected while transferring enough bricks; to solve the above problems, the embodiment of the present invention provides an intercepting plate 21, and when clamping bricks, the position of the receiving frame 1 is controlled by the driving component 11, so that the clamping plate 13 is located in the clamping position, and then the third hydraulic cylinder 3 is connected to the connecting member 13 to control the position of the receiving frame 13. The connecting piece 31 and the linkage plate 32 drive the push plate 33 to squeeze the side of the brick, and the other side of the brick is supported by the intercepting plate 21; it should be pointed out that the position where the push plate 33 cooperates with the intercepting plate 21 to clamp is the side position after the bricks are arranged; then the first hydraulic cylinder 12 controls the clamping plate 13 to clamp and fix the outermost bricks after the bricks are arranged; therefore, the arranged bricks are clamped and fixed from two directions, maintaining a stable clamping effect during the transfer process, and there is no need to apply much squeezing force to one clamping direction, thereby protecting the bricks.

[0037] A plurality of fourth hydraulic cylinders 34 are arranged on the side of the push plate 33 away from the intercepting plate 21, and the end of the output end of the fourth hydraulic cylinder 34 passes through the push plate 33 and is provided with an adjustment plate 35; for the transfer of bricks arranged in different numbers, when clamping and fixing, the fourth hydraulic cylinder 34 drives the adjustment plate 35 to squeeze the side of the brick, and the second hydraulic cylinder 23 and the first connecting frame 22 drive part of the intercepting plate 21 to move upward in the plug-in hole 2; the remaining intercepting plate 21 cooperates with the adjustment plate 35 to clamp the side of the brick, thereby avoiding interference between the clamping plate 13 and the push plate 33 and the intercepting plate 21.

[0038] like Figures 4 to 8 As shown, the connecting member 31 includes a cylinder 312 and a piston 311; the piston 311 is connected to the output end of the third hydraulic cylinder 3; the cylinder 312 is installed on the side of the linkage plate 32, and the piston 311 slides inside the cylinder 312; the side of the cylinder 312 is connected to a pressure relief valve 313; after the bricks are transferred to the stacked bricks, the transferred bricks need to be pushed to dock with the bricks on the stack; specifically, when the third hydraulic cylinder 3 drives the push plate 33 to squeeze the side of the brick through the connecting member 31 and the linkage plate 32, the air pressure in the cylinder 312 is the same as the squeezing force of the push plate 33 on the brick; and the pressure relief valve 313 automatically releases the pressure when the air pressure in the cylinder 312 reaches a certain level, and the piston 311 squeezes the gas in the cylinder 312 to be buffered, so as to avoid excessive thrust during the pushing process of the bricks and push down the stacked bricks.

[0039] A hose 314 is provided on the side of the cylinder 312, and an air pump 315 is provided on the end of the hose 314 away from the cylinder 312; when in use, the air pump 315 continuously inflates the interior of the cylinder 312 through the hose 314; when in use, the air pump 315 continuously inflates the interior of the cylinder 312 through the hose 314, so that the gas inside the cylinder 312 remains full, and the air can be reused, which facilitates the continuity of the brick stacking operation.

[0040] like Figures 4 to 10 As shown, a fifth hydraulic cylinder 4 is provided at the top of the receiving frame 1, a second connecting frame 41 is provided at the output end of the fifth hydraulic cylinder 4, a receiving plate 42 is provided at the end of the second connecting frame 41 away from the fifth hydraulic cylinder 4, and the receiving plate 42 is located below the clamping plate 13; when the bricks are transferred to the specified position, the receiving plate 42 is controlled by the fifth hydraulic cylinder 4 and the second connecting frame 41 to move to the bottom of the clamped bricks, and then the bricks are pushed to dock with the bricks on the stack through the adjustment plate 35. The docking process avoids the relative movement between the transferred bricks and the bricks on the stack by setting the receiving plate 42, thereby avoiding friction loss caused by the relative movement between the bricks.

[0041] A plurality of receiving rollers 43 are rotatably provided at the top end of the receiving plate 42; the receiving rollers 43 are provided to reduce the friction between the receiving plate 42 and the bricks, thereby further protecting the bricks.

[0042] When the adjustment plate 35 pushes the brick to the specified position, the clamping plate 13 is first released from the brick, and then the brick is pushed to the specified position by the adjustment plate 35, and the clamping plate 13 is controlled to clamp the brick again; then the receiving plate 42 is pulled out, and finally the brick is released; when the brick is released, it moves downward as a whole, and will not tilt due to the withdrawal process of the receiving plate 42, so that the bricks are neatly placed downward, ensuring the stability of the stacking.

[0043] When the moving bricks reach the stacking position, the bottom end of the receiving plate 42 is received by the top end of the stacked bricks, thereby avoiding the receiving plate 42 from tilting due to the weight of the bricks when receiving the bricks, and further improving the stability and accuracy of the brick stacking.

[0044] A pair of vibrators 10 are arranged at the top of the receiving frame 1; when the stacking is completed, the vibrators 10 are started, and the vibrators 10 will drive the receiving frame 1 and the connected structure to vibrate, so that the foreign particles attached to the clamping plate 13, the intercepting plate 21 and the adjusting plate 35 are vibrated and fall off, thereby preventing the brick particles from affecting the clamping effect; it should be pointed out that in the process of brick production, foreign particles will inevitably appear, and when the foreign particles adhere to the clamping surface of the clamping structure, the friction between the clamping surface and the brick will be reduced, thereby affecting the clamping effect.

[0045] A detection plate 51 is provided on the side of the receiving frame 1, and a pair of connecting springs 52 are symmetrically provided at both ends of the detection plate 51, and the end of the connecting spring 52 away from the detection plate 51 is connected to the receiving frame 1; when the intercepting plate 21 moves up and down, the side is slidably connected with the detection plate 51; an early warning device 5 is provided on the side of the receiving frame 1; the pressure-bearing end of the early warning device 5 contacts the side of the detection plate 51; when the intercepting plate 21 bears the pressure of bricks for a long time, it will bend; therefore, the detection plate 51 is provided, and when the intercepting plate 21 bends, as the intercepting plate 21 moves upward, The bent intercepting plate 21 squeezes the detection plate 51, which in turn causes the intercepting plate 21 to stretch the connecting spring 52 and squeeze the pressure surface of the early warning device 5. The early warning device 5 sends out an early warning signal to remind the staff to replace it; to avoid the intercepting plate 21 being continued to be used after being bent and damaged, affecting the use effect; it should be pointed out that when in use, the second hydraulic cylinder 23 drives the intercepting plate 21 to move upward through the first connecting frame 22, so as to avoid affecting the alignment between the transferred bricks and the bricks on the stack; therefore, each time the bricks are transferred, the intercepting plate 21 will be driven to move upward.

[0046] During operation, when clamping bricks, the position of the receiving frame 1 is controlled by the driving component 11, so that the clamping plate 13 is in the clamping position, and then the third hydraulic cylinder 3, the connecting piece 31 and the interlocking plate 32 drive the push plate 33 to squeeze the side of the brick, and the other side of the brick is received by the intercepting plate 21; it should be pointed out that the position where the push plate 33 cooperates with the intercepting plate 21 to clamp is the side position after the bricks are arranged; then the first hydraulic cylinder 12 is used to control the clamping plate 13 to clamp and fix the outermost bricks after the bricks are arranged; therefore, the arranged bricks are clamped and fixed from two directions, and a stable clamping effect is maintained during the transfer process, and there is no need to apply much squeezing force to one clamping direction, so as to protect the bricks; among them, for the transfer of bricks with different numbers of arrangements, when clamping and fixing, the fourth hydraulic cylinder 34 is used to drive the adjusting plate 35 to squeeze the side of the brick, and the second hydraulic cylinder 23 and the first connecting frame 22 drive part of the intercepting plate 21 to clamp. The cut-off plate 21 moves upward in the plug-in hole 2; the remaining intercepting plate 21 cooperates with the adjusting plate 35 to clamp the side of the brick, avoiding interference between the clamping plate 13 and the push plate 33 and the intercepting plate 21; after the brick is transferred to the stacked brick, it is necessary to push the transferred brick to dock with the brick on the stack; specifically, when the third hydraulic cylinder 3 drives the push plate 33 to squeeze the side of the brick through the connecting piece 31 and the linkage plate 32, the air pressure in the cylinder 312 is the same as the squeezing force of the push plate 33 on the brick; and the pressure relief valve 313 automatically releases the pressure when the air pressure in the cylinder 312 reaches a certain level, and the piston 311 squeezes the gas in the cylinder 312 to be buffered, avoiding excessive thrust during the pushing process of the brick and pushing down the stacked brick; when in use, the air pump 315 continuously inflates the interior of the cylinder 312 through the hose 314, so that the gas inside the cylinder 312 remains full and can be reused, which is convenient for the continuity of the brick stacking operation.

[0047] When the bricks are transferred to the designated position, the receiving plate 42 is controlled by the fifth hydraulic cylinder 4 and the second connecting frame 41 to move to the bottom of the clamped bricks, and then the bricks are pushed to dock with the bricks on the stack by the adjusting plate 35.
