[0019] The utility model will be further described below in connection with the drawings and examples.

[0020] As Figs. 1-3 Indicated, a kind of wind-driven sample delivery coal bottle automatic opening and closing cover device, including fixed unit and opening and closing cover unit;

[0021] The fixed unit includes first air cylinder 4 and coal bottle mouth fixed plate 5, the first air cylinder 4 is vertically arranged in the edge of carousel 1 at coal bottle 2 fixed point position, auxiliary fixture 3 is also provided on carousel 1 at coal bottle 2 fixed point position, the coal bottle mouth fixed plate 5 is horizontally arranged in the upper end of first air cylinder 4, the inside of coal bottle mouth fixed plate 5 is provided with coal bottle mouth fixed hole and it is opposite fixed point position, the initial state of first air cylinder 4 is in elongation state, so that the height of coal bottle mouth fixed plate 5 is greater than the height of coal bottle 2;

[0022] The opening and closing cover unit includes second air cylinder 7 and three grab air cylinder 9, the second air cylinder 7 is vertically fixed on the device above coal bottle 2 fixed point position by mounting seat 6, the three grab air cylinder 9 is fixed on the lower end of second air cylinder 7 by connecting seat 8, the front end of three grab air cylinder 9 three grabs is respectively provided with three support claws;

[0023] First air cylinder 4, second air cylinder 7 and three grab air cylinder 9 are electrically connected with the control system of coal coke intelligent robot analysis system.

[0024] The working process of the utility model:

[0025] In use, a chip code scanner is provided beside the installation point of the turntable 1, and the chip code scanner is aligned with the position of the coal bottle 2. The manual sample and the machine sample can be identified by scanning the code, so that the machine sample is separated and automatically opened, and the manual sample does not need to be automatically opened, but is directly pushed into the manual temporary storage cabinet. The lower end of the coal bottle 2 is clamped by the auxiliary clamp 3 to prevent shaking. After the coal bottle 2 reaches the opening position, the control system senses the coal bottle information through the photoelectric switch, controls the first cylinder 4 to retract, drives the coal bottle mouth fixing plate 5 to descend, and makes the coal bottle mouth fixing hole be sleeved on the coal bottle 2 to clamp the shoulder of the coal bottle 2.

[0026] Initially, the second cylinder 7 is in a retracted state, and the three-grabbing cylinder 9 is in a closed state, and the three supporting claws are an integral whole. After the coal bottle 2 is fixed, the second cylinder 7 is controlled to extend, and the three supporting claws at the lower end of the three-grabbing cylinder 9 exert a downward pressure on the center of the bottle cap. When the pressure reaches a preset value, the bottle cap spring is retracted, and the bottle cap is loosened. The sensor receives the signal feedback to the control system, and the second cylinder 7 is controlled to stop extending.

[0027] After the bottle cap is loosened, the three-grabbing cylinder 9 is controlled to open, and the three supporting claws are driven to open. The height of the three supporting claws is adjusted through the second cylinder 7, so that the three supporting claws clamp the bottle cap. Then, the second cylinder 7 is retracted to lift the bottle cap, and the bottle cap is opened. Then, the bottle cap is transported to a specified position for sample sub-packaging. After the sample sub-packaging is completed, the bottle cap is returned to the opening position. The second cylinder 7 is extended to drive the supporting claws to descend, and the bottle cap is loosened and then rises. The spring rebounds, the bottle cap is closed, and the coal bottle is transported to the return position to wait for the return.
