s101, when producing the jth concrete block, first calculating a weight difference between a first corresponding amount of concrete of the jth concrete block and intermediate concrete poured during preparation of the jth concrete block, wherein j is an integer greater than 0 and an initial value is 1, and when j is 1, the weight of the intermediate concrete poured during preparation of the jth concrete block is 0, then controlling the pouring device to pour the concrete with the weight difference through the first through hole 2, wherein the upper surface of the concrete on the two sliding plates 11 after pouring the concrete is higher than the upper end of the first heating plate 5, as shown in fig. 8(b), the first telescopic rod 6 remains unchanged and does not extend downwards under the action of the spring after pouring the concrete, the two sliding plates 11 remain abutted against the lower end of the first heating plate 5, and at this time, controlling the heating wires on the two sliding plates 11 and the four first heating plates 5 to abut against the concrete surrounded by the four first heating plates 5 Heating to remove air in the concrete, and after heating for a preset time, curing the concrete surrounded by the four first heating plates 5 to form a first layer of concrete of the jth concrete brick;

Step S102, controlling the pouring device to pour i +1 th concrete through the first through hole, where i is an integer greater than 0 and the initial value is 2, during pouring the i +1 th concrete, part of the concrete flows into a void formed when air in the ith concrete layer is removed, controlling the two sliding plates to stop heating when the i +1 th concrete begins to be poured, the first telescopic rod gradually extends downwards, the relative position of the first heating plate and the concrete changes, after the i +1 th concrete is completely poured, the lower end of the first heating plate is located below the upper surface of the ith concrete layer, and the upper surfaces of the concrete on the two sliding plates are higher than the upper end of the first heating plate, as shown in fig. 8(c) (i ═ 1 in fig. c), while the first telescopic rod gradually extends downwards, for each connecting wire, the connecting wire drives the corresponding sliding plate to slide towards the corresponding first groove, at the moment, only the parts of the ith concrete and the (i + 1) th concrete surrounded by the four first heating plates are heated by the four first heating plates to remove air in the concrete, after the parts are heated for the preset time, the concrete surrounded by the four first heating plates is cured to form the (i + 1) th layer of concrete of the jth concrete brick, i + +, and whether i is equal to N-1 is judged, if so, step S103 is executed, otherwise, the step S102 is executed again.
In this embodiment, when the first portion of concrete is heated, two sliding plates and four first heating plates are used for heating, and when the 2 nd to N th portions of concrete are heated, only four first heating plates are used for heating, because the two first sliding plates still keep abutting against the lower ends of the four first heating plates when the first portion of concrete is heated, the lower end of a square formed by the first portion of concrete can be uniformly heated by the two sliding plates, when the 2 nd to N th portions of concrete are heated, because the first telescopic rod can drive the supporting plate to move downwards, the two sliding plates can be gradually folded into the corresponding first grooves, the area of the sliding plate contacting with the lower surface of the concrete brick is gradually reduced, if the two sliding plates are still used for heating at this time, the non-uniformity of the temperature of the middle portion and the temperature of the peripheral portion of the concrete brick can be intensified, in the process of completing the curing of the middle part of the concrete block, not only the part surrounded by the four first heating plates but also the part above the four first heating plates in the peripheral part are cured, which is not favorable for the firmness of the curing and forming of two adjacent parts of concrete. Therefore, when the 2 nd to N th parts of concrete are heated, the concrete surrounded by the four first heating plates is heated only by the four first heating plates, and after the (i + 1) th layer of concrete surrounded by the four first heating plates is cured, the residual concrete belonging to the (i + 1) th part of concrete above the (i + 1) th layer of concrete can be more easily kept in a non-cured state so as to be mixed and cured with the next part of concrete, so that the quality and the firmness of the formed brick to be produced are improved.

step S104, controlling each first heating plate to stop heating, controlling the tilting device to pour intermediate concrete into the first through hole, similarly, in the process of pouring the intermediate concrete, enabling part of the concrete to flow into a pore space generated by the Nth layer of concrete when air is removed, after the (N + 1) th part of the concrete is completely poured, driving the corresponding sliding plates to be respectively folded into the corresponding first grooves by the two connecting lines, enabling the formed jth concrete brick containing the 1 st to Nth layers of concrete to pass through the second through hole and fall onto the placing plate, enabling the jth concrete brick to completely pass through the second through hole, enabling the two sliding plates to restore to the initial state where the opposite sides abut against each other under the action of the elastic ropes, and dividing the jth concrete brick from the intermediate concrete in the process of restoring the two sliding plates to the initial state, thereby completing the preparation of the jth concrete brick, and j + +, then, returning to the step S101, and entering the preparation of the next concrete brick.
In addition, if the heat radiating plate is directly connected to the first vertical plates, the heat radiating plate may transfer a part of heat to the first vertical plates, and a part of concrete may adhere to the first vertical plates when the concrete is poured into the space region surrounded by the four first vertical plates. When the two sliding plates slide and are folded into the corresponding first grooves respectively, the distance between the lower surface of the supporting plate and the placing plate is equal to the maximum thickness of the concrete bricks allowed to be produced, and therefore the concrete bricks of various specifications can be guaranteed to completely pass through the second through hole. In order to avoid the performance change of the elastic ropes, a second heat insulation plate is arranged at the connecting position of each sliding plate and the corresponding elastic rope.
According to the embodiment, when the concrete brick is prepared, the concrete is divided into a plurality of layers for layered preparation, so that the amount of pores generated when the air in the concrete is removed can be reduced, the compactness of the concrete brick is improved, and for each layer of concrete in 1-N-1 layers, the amount of the corresponding part of concrete poured in the preparation process is larger than that of the concrete required for preparing the layer of concrete; when the Nth layer of concrete is prepared, the upper surfaces of the concrete on the two sliding plates are lower than or equal to the upper end of the first heating plate after the Nth part of concrete is poured, so that concrete bricks with different thicknesses can be prepared, and after the concrete of each layer is prepared, the whole prepared concrete brick can fall onto the placing plate from the second through hole by adding the middle concrete so as to be convenient for preparing the next concrete brick.
