DETAILED DESCRIPTION

[0024] like Figures 1 to 10 As shown, the present invention mainly includes a first conveyor 1, a blocking unit 2, a toggle unit 4, a transition block 3, a lifting frame 5, a lifting unit, a lifting unit, a second conveyor 73 and a folding conveying unit. The present invention is described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, the first conveyor 1 is a belt conveyor, which is arranged at the front end of the entire transfer system. When in use, the coal sample barrels are placed one by one on the first conveyor. A blocking unit is provided above the rear end of the first conveyor, and the blocking unit includes a rotating wheel 21 and a block 22 fixed on the outer wall of the rotating wheel. The block includes an arc-shaped part and a straight part, and the arc-shaped part and the straight part are arranged tangently, and the arc-shaped part of the block is in contact with the circular outer wall of the rotating wheel. When the straight part of the block is vertically downward, the vertical part of the block can contact the coal sample barrel, thereby preventing the coal sample barrel from moving backward with the first conveyor. After the rotating wheel swings 90 degrees counterclockwise, the block is in a horizontal state. At this time, the lowest point of the block is higher than the highest point of the coal sample barrel, and the coal sample barrel can pass through the block and continue to move backward. The function of the blocking unit is to contact the coal sample barrel to prevent the coal sample barrels from moving to the rear end of the first conveyor.

[0026] A transition block 3 is provided at the rear end of the first conveyor. The upper surface of the transition block is an inclined surface 31. The upper end of the inclined surface is connected to the conveyor belt of the first conveyor. After the coal sample bucket on the first conveyor moves to the inclined surface, it can move from top to bottom along the inclined surface. A horizontal surface is provided at the lower end of the transition block, and the horizontal surface is connected to the lower end of the inclined surface.

[0027] A toggle unit is provided above the lower end of the transition block, such as Figure 2 As shown, the toggle unit includes a toggle motor 41 arranged above the lower end of the transition block, a toggle rod 42 fixed to the output end of the toggle motor, an ear plate 44 fixed to the side wall of the lower end of the toggle rod, and an extension rod 43 hingedly connected to the ear plate, and the mounting end of the extension rod overlaps a portion of the free end of the toggle rod. When the toggle rod swings counterclockwise, the mounting end of the extension rod maintains surface contact with the outer wall of the free end of the toggle rod, which can drive the extension rod to swing synchronously. When the toggle rod rotates clockwise, the extension rod can swing with the toggle rod but does not move synchronously with the toggle rod; and after the free end of the extension rod contacts the coal sample barrel, the extension rod can swing counterclockwise. After the coal sample barrel slides along the inclined surface to the horizontal surface of the transition block, the toggle unit is actuated to cause the toggle rod to swing counterclockwise, and then the coal sample barrel is toggled by the extension rod so that the coal sample barrel moves to the rear side into the lifting frame.

[0028] like Figure 3 As shown, the lifting frame 5 is a rectangular hollow structure, and guide rails are arranged in the lifting frame. The guide rails include a first outer rail 51, a first inner rail 52, a second outer rail 54, and a second inner rail 55, which are arranged in sequence from the outside to the inside. A rectangular slide 53 is formed between the first outer rail 51 and the first inner rail 52, and between the second outer rail 54 and the second inner rail 55, and the corners of the slide are rounded. A reinforcing rod 56 is provided between the first outer rail 51 and the first inner rail 52, and between the second outer rail 54 and the second inner rail 55 to maintain the stability of the slide. An annular groove 57 is formed between the first inner rail and the second outer rail, and the annular groove is rectangular as a whole, and the corners are rounded.

[0029] A lifting unit 6 is provided in the lifting frame, and the setting of the lifting unit is used to realize the lifting of the barrel clamp. Figure 5 As shown, the barrel clamp includes a pair of side plates 63 arranged front and back, the side plates are "L" shaped, a first connecting rod 64 is provided on the side wall of the side plate, and a sliding rod 65 is provided on the left and right sides of the first connecting rod. The first connecting rod is used to extend into the annular groove, and the sliding rod is used to extend into the corresponding slideway, and the sliding rod is slidably connected with the slideway. Figure 4 , Figure 6As shown, the lifting unit includes two groups of lifting sprockets 61, a lifting chain 62 arranged between the lifting sprockets arranged in groups, and a barrel clamp arranged between the two chains. The lifting sprockets arranged in groups include four lifting sprockets located at the four vertices of the rectangle. The first connecting rod on the side plate passes through the annular groove and is fixedly connected to the lifting chain. When the lifting chain moves, it can drive the barrel clamp to move along the slideway, and when the barrel clamp moves from bottom to top, the barrel clamp is lifted. Due to the sliding connection between the slide bar and the slideway, the barrel clamp always maintains a fixed posture when sliding from bottom to top. There are several barrel clamps. In this embodiment, there are three barrel clamps, and the three barrel clamps are arranged at equal intervals on the lifting chain. When the barrel clamp is lifted to connect with the horizontal plane at the lower end of the transition block, the toggle unit can toggle the coal sample barrel onto the barrel clamp. At this time, the coal sample barrel is located between the two clamps that constitute the barrel clamp.

[0030] When placing the coal sample barrels into the sample delivery vehicle, since the coal sample barrels are placed at different heights, the setting of the lifting unit can meet the placement needs of the coal sample barrels at different heights.

[0031] A lifting unit and a second conveyor 73 are provided on the lifting frame to receive and transfer the coal sample barrel on the barrel clamp. Figure 1 , Figure 7 As shown, an auxiliary frame 7 is fixed on the side wall of the lifting frame, and a lifting frame 71 that moves up and down is slidably installed on the auxiliary frame 7. A second conveyor 73 is provided on the inner side of the lifting frame, and a lifting unit that drives the lifting frame to move up and down is provided on the auxiliary frame. The lifting unit includes a pair of lifting sprockets 74 arranged up and down, and a lifting chain 75 arranged between the two lifting sprockets. The second conveyor is a belt conveyor, and the second conveyor is always in a horizontal state. The front end of the second conveyor is a feeding end 731, which extends into the lifting frame and reaches between the front and rear guide rails. A material-beating cylinder is provided on the lifting frame. When the belt of the second conveyor is flush with the lower surface of the coal sample barrel on the barrel clamp, the material-beating cylinder moves to push the coal sample barrel onto the second conveyor, and then the coal sample barrel moves from front to back under the action of the second conveyor. A folding conveying unit is provided on the rear side of the second conveyor. The folding conveying unit can be extended or shortened, and can also receive the coal sample barrel on the second conveyor, and continue to convey the coal sample barrel, and finally convey the coal sample barrel to the sample delivery vehicle.

[0032] like Figure 1 , Figure 8As shown, the folding conveying unit includes an extension frame 8 fixed on the lifting frame, a third conveyor 81, a fourth conveyor 82 and a fifth conveyor 83 which are slidably arranged on the extension frame and arranged sequentially from top to bottom, and an extension mechanism arranged inside the extension frame and driving the third to fifth conveyors to approach or move away from the lifting frame. The third to fifth conveyors are arranged sequentially from top to bottom and are all slidably connected to the extension frame. The extension mechanism includes a spring seat 85, an extension spring 84 arranged between the spring seat and the third to fifth conveyors, a folding motor 86, a wire wheel 87 fixed at the output end of the folding motor, and a pull rope 88 arranged between the outer wall of the wire wheel and the third to fifth conveyors. The folding motor and the spring seat of the extension mechanism driving the third conveyor are fixed on the lifting frame, the folding motor and the spring seat of the extension mechanism driving the fourth conveyor are fixed on the third conveyor, and the folding motor and the spring seat of the extension mechanism driving the fifth conveyor are fixed on the fourth conveyor. Under the action of the extension spring, there is a tendency to drive the third to fifth conveyors to move to the side away from the lifting frame. And when the extension spring is in a natural state, the total length of the third, fourth and fifth conveyors is the largest. The folding motor drives the wire wheel to rotate, so that the pull rope is wound on the wire wheel. At this time, the elastic force of the extension spring can be overcome, so that the third to fifth conveyors move to the side close to the lifting frame. When in use, according to the arrangement of the coal sample barrels in the sample delivery vehicle, the length of the folding conveying unit is adjusted to meet the placement needs of the coal sample barrels. The coal sample barrel can be transferred from the second conveyor to the third conveyor, then from the third conveyor to the fourth conveyor, and finally to the fifth conveyor. Take the coal sample barrel 9 from the fifth conveyor for placement.

[0033] like Fig.10 As shown, the transfer route of the coal sample barrel is: first conveyor → transition block → barrel clamp → second conveyor → third conveyor → fourth conveyor → second conveyor. When moving from the first conveyor to the transition block, it relies on the gravity of the coal sample barrel, and then when moving from the transition block to the barrel clamp, it relies on the toggle mechanism; when moving from the barrel clamp to the second conveyor, it relies on the punching cylinder; then it moves from the second conveyor to the third conveyor, and then to the fourth conveyor, and then to the fifth conveyor, relying on the gravity of the coal sample barrel. In this process, the lifting unit lifts the coal sample barrel, and according to the need for placement height, the lifting unit moves to adjust the height of the second conveyor.

[0034] The present invention can horizontally transfer and lift the coal sample bucket according to the need of placement height, and can adjust the lifting height of the coal sample bucket at will to achieve the purpose of saving time and labor.
