In this embodiment, the mounting manner of the cylinder cover 2 on the first cylinder 1 is as follows:
when the cylinder cover 2 needs to be fixed on the first cylinder 1, the cylinder cover 2 is firstly placed at the opening of the first cylinder 1, the second cylinder 7 is driven to rotate by the anticlockwise rotating turntable 6 (because the second cylinder 7 drives the first gear 20 to rotate clockwise at this moment, the second gear 23 only rotates under the limiting effect of the limiting groove 21 and can not move along the groove body direction of the limiting groove 21), so that the second gear and the screw 8 interact with each other in a threaded manner, the screw 8 drives the butt-joint column 4 to be inserted into the column slot 9, the preliminary fixation of the cylinder cover 2 on the first cylinder 1 is completed, the hook 12 can touch the guide slope 14 to centripetally deflect (compress the first spring) and cross the gap between the guide slopes 14 along with the gradual entering of the butt-joint column 4 into the column slot 9, and then the butt-joint column 4 is locked in the column slot 9 through the clamping of the plane clamping of the top of the hook 12 at the bottom of the guide slope 14, and further the further fixation of the cylinder cover 2 on the first cylinder 1 is completed.
During the period, when the butt-joint column 4 does not move in the column slot 9 in the accommodating groove 5, the coil spring is in a non-deformation state, the pull rope is in a loose state, and the second spring in the sliding groove 16 enables the roller on the cross rod 27 to press the guide part 15 by pushing the sliding block 17 and the connecting rod 18, so that the first spring is compressed, and the hook parts 12 are in a gathering state. And as the docking post 4 moves towards the post slot 9 and before the hook 12 touches the guiding slope 14, the pull rope starts to be gradually tightened, and pulls the connecting rod 18 to drive the cross rod 27 to move upwards so as to be separated from the guiding portion 15, the swing arm 10 swings (the first spring returns to the non-deformation state) to enable the hook 12 to be in the separation state, and at the moment, the compression deformation amount of the second spring is gradually increased.

The dry mix storage device for concrete experiments according to claim 7, wherein a chute is fixed in the cavity, a slide block is connected in the chute in a sliding manner, a connecting rod is fixedly inserted on the slide block, the bottom of the connecting rod is fixed at the top of the cross rod, a second spring is sleeved outside the connecting rod, and two ends of the second spring are respectively fixed on the top of the slide block and the corresponding chute wall of the chute; when the roller moves downwards and does not touch the guide part, the second spring is in a compression deformation state.
9. The dry mix storage device for concrete experiments according to claim 8, wherein a fixed disc is arranged in the cylinder cover, the second cylinder penetrates through the center of the fixed disc and can rotate relative to the fixed disc, a first gear is sleeved and fixed on the outer side of the second cylinder, a limiting groove is obliquely fixed at the bottom of the fixed disc, a limiting shaft capable of moving along a groove body of the limiting groove is elastically inserted in the limiting groove, a second gear meshed with the first gear all the time is rotatably sleeved on the limiting shaft, a reel is inserted at the bottom of the fixed disc through a coil spring, a third gear matched with the second gear is sleeved and fixed on the outer side of the reel, a wire wheel is sleeved and fixed at the bottom of the third gear, a pull rope is wound on the wire wheel, and the free end of the pull rope is fixedly connected to the top of the connecting rod in a bolt manner;
when the butt-joint column is separated from the column slot, the second gear is meshed and rotated by the first gear, and can move to be meshed with the third gear along the limit groove through the limit shaft, so that the wire wheel is forced to perform rope paying-off operation.
10. The dry mix storage device for concrete experiments of claim 9, wherein:
when the butt-joint column does not enter the column slot, the cross rod presses the guide part through the roller under the action of the elasticity of the second spring to force the hook part to centripetally deflect, and the pull rope is in a loose state;
when the butt-joint column is inserted into the column slot, the pull rope starts to be gradually tightened, the connecting rod is pulled to drive the cross rod to move upwards so as to be separated from the guide part, and the compression deformation quantity of the second spring is gradually increased.
