The utility model has the advantages of convenient prefabricated part taking and placing, and reducing operation process, and is mainly used for prefabricated part taking and placing.

[0004] However, the above-mentioned patent still has some disadvantages in use: when working, the material is placed on the push plate, and the push plate is easily shaken and dumped when moving into the push plate kiln, which causes the material to fail to be built, causes the waste of material, increases the input cost, does not meet the actual use requirement, and the structure for placing the article cannot be flexibly adjusted. Under certain production conditions, different sizes of firebrick green bricks need to be placed in the furnace for firing together, which affects the firing.

At this time, the expansion block 10 above the second fixed screw cylinder 7 can also limit and fix the refractory bricks. Since there is a gap between the stacked refractory bricks, the height of the expansion plate can be changed by rotating the second adjusting screw 8, thereby avoiding the adhesion between the upper and lower refractory bricks, which affects the heat transfer, thereby ensuring the subsequent firing effect. After the refractory bricks are stacked, the unprocessed refractory bricks existing in the push plate structure 16 can be pushed into the push plate kiln main body 2 for firing operation by pushing the hydraulic rod 19. The push plate structure 16 with fired refractory bricks can be extruded. When the push plate structure 16 is running, the heat insulation doors 23 on both sides are in closed state, which can avoid heat overflow when the kiln is opened. After the push plate structure 16 is changed, the kiln door 13 can be reset to close the push plate kiln. Then, the circulating fan 17 on the top of the return cover 11 can suck the heat overflowed from the kiln and the heat of the fired refractory bricks existing in the return cover 11, so that this part of heat can be introduced into the push plate kiln for reuse. At the same time, the return cover 11 can be cooled to avoid scalding the operator, improving the overall use effect of the device. The device has the advantages of adjustable bearing space, good applicability, and heat insulation and recycling of kiln opening.
