[0031] When testing the building wall materials, the spring buckle 5 must be opened first, and then the threaded rod 6 must be rotated, so that the threaded rod 6 can push the upper layer 4 upward, and then the upper layer 4 is separated from the frame 3, and then the building materials are built into the frame 3, and a thickened pressing plate is placed on the upper side of the building materials, and then the upper layer 4 is put back on the upper side of the frame 3, and the threaded rod 6 is rotated to move the upper layer 4 downward, so that the upper layer 4 presses the thickened pressing plate downward, so that the building materials are compacted to simulate the real use environment, and then the spring buckle 5 is locked, so as to complete the building material masonry;

[0032] When drying building materials, the sealing plate 701 can be moved to the left to contact the right side of the frame 3, and then the hot air blower 703 is started, so that the hot air blower 703 pumps hot air into the exhaust box 709 through the air pipe 704, so that the heated air flow is evenly discharged through the air groove on the left side of the exhaust box 709, so that it blows on the wall surface, and at the same time, the first motor 706 is started, so that the first motor 706 drives the winding rod 705 to reciprocate through the bevel gear 707, so that the winding rod 705 reels or loosens the pull rope 708, so that the pull rope 708 hoists and pulls the exhaust box 709, and then the exhaust box 709 moves up and down, and the wall surface is evenly dried, and the heated air flow is discharged through the exhaust port 702, so that the wall material can be quickly and evenly dried;

[0033] The overheating prevention mechanism 8 includes a cross bar 801, both ends of which are fixedly connected to the outer wall of the mounting frame 1, a second motor 802 is fixedly connected to the inner wall of the middle part of the cross bar 801, a transmission wheel 803 is fixedly connected to the outer wall of the second motor 802, a threaded column 804 is rotatably connected to the left part of the upper side of the mounting frame 1 through a bearing, the right end of the threaded column 804 sequentially penetrates the threaded column 804 and the sealing plate 701, the outer wall of the threaded column 804 is rotatably connected to the inner wall of the frame 3 through a bearing, the outer wall of the threaded column 804 is threadedly connected to the inner wall of the sealing plate 701, and the outer wall of the left end of the threaded column 804 is connected to the transmission wheel 80 3 is sleeved with a transmission chain 805, the outer wall of the transmission wheel 803 is connected to the outer wall of the threaded column 804 through the transmission wheel 803, the upper side of the cross bar 801 is provided with a control module 806, the second motor 802 is electrically connected to the control module 806, and the humidity monitor 710 is electrically connected to the control module 806. When the humidity monitor 710 detects that the moisture content of the airflow is lower than a preset threshold, the second motor 802 can be started through the control module 806, so that the second motor 802 drives the threaded column 804 to rotate through the transmission wheel 803 and the transmission chain 805 to push the sealing plate 701 away from the frame 3;

[0034] During the wall drying process, the airflow is always discharged from the exhaust port 702. During this process, the humidity monitor 710 detects the moisture in the airflow in real time. When the moisture in the airflow is lower than the preset threshold, the control module 806 starts the second motor 802, so that the second motor 802 drives the transmission wheel 803 to rotate, and then drives the threaded column 804 to rotate through the traction of the transmission chain 805. Since the outer wall of the threaded column 804 is threadedly connected with the inner wall of the sealing plate 701, and the sealing plate 701 is slidably connected with the mounting frame 1 and cannot rotate, the sealing plate 701 will be pushed to the right, so that the outer wall of the sealing plate 701 is separated from the outer wall of the frame 3, so that the wall can quickly dissipate heat, so that it enters the detection process, and avoids damage caused by excessive wall drying;

[0035] The anti-adhesion mechanism 711 includes a tooth groove 101, which is provided at the front of the left inner wall of the sealing plate 701 and the rear of the left inner wall of the sealing plate 701. A fixing frame 102 is fixedly connected to the lower side of the exhaust box 709. A rotating rod 103 is rotatably connected to the lower inner wall of the fixing frame 102 through a bearing. Both ends of the rotating rod 103 extend to the inside of the tooth groove 101. A gear 104 is fixedly connected to the outer wall of the rotating rod 103. A brush 105 is fixedly connected to the middle of the outer wall of the rotating rod 103. A protruding tooth structure is provided on the inner wall of the tooth groove 101, and the outer wall of the gear 104 meshes with the tooth structure of the inner wall of the tooth groove 101. The left side of the brush 105 protrudes to the left relative to the left side of the outer wall of the sealing plate 701.

[0036] When the exhaust box 709 moves up and down reciprocatingly, the fixed frame 102 and the rotating rod 103 will be driven to move up and down synchronously. Since the outer wall of the rotating rod 103 is fixedly connected to the gear 104, and the outer wall of the gear 104 is meshed with the inner wall of the tooth groove 101, the rotating rod 103 can synchronously reciprocate and rotate as the exhaust box 709 moves up and down. The rotation of the rotating rod 103 will drive the brush 105 to rotate. The outer wall of the brush 105 protrudes to the left relative to the outer wall of the tooth groove 101, and the outer wall of the brush 105 will contact the wall surface. When the brush 105 rotates, it will remove the moisture seeping from the wall surface or the powdery detached matter adhering to the wall surface, so that the wall surface can be dried by the airflow faster.

[0037] Since the bristles on the surface of the brush 105 are elastic, they will rebound at the moment of separation after contacting the wall, and the moisture on its surface will be thrown to the inner wall of the sealing plate 701, making it easier for the moisture condensed on the inner wall of the sealing plate 701 to flow downward, thereby reducing the heat loss caused by the thermal conduction of the moisture on the inner wall of the sealing plate 701, and the dust brushed off after the wall is partially dry can absorb the moisture in the airflow in the airflow, reducing the environmental moisture and speeding up the drying speed.
