Detailed Description

As shown in fig. 1 to 8, the present invention mainly includes a housing 1, a water pipe 2, a dial wheel 3, and a pickup unit, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a casing 1 is a basic component of the present invention, the casing is a rectangular parallelepiped, charging barrels 11 are fixed on the left and right side walls of the upper part of the casing, and the charging ports of the charging barrels are arranged upward as shown in fig. 7, so as to facilitate the charging of coal 8. Two guide blocks 12 are arranged at the bottom of the inner cavity of the shell, the guide blocks are arranged in front and at the back, the guide block on the left side is in contact with the left side wall of the shell, and the guide block on the right side is in contact with the right side wall of the shell. The guide block is provided with an arc surface 13 which is tangent with the bottom of the inner cavity of the shell and the left side wall or the right side wall of the inner cavity of the shell. The guide block is arranged, so that water at the bottom of the inner cavity of the shell can flow to the upper part of the inner cavity of the shell conveniently, and the guide block plays a role in guiding the water. Two shifting wheels 3 which are arranged left and right are arranged on the inner side of the shell, and the shifting wheels are rotationally connected with the shell. A plurality of blades 31 are fixed on the cylindrical outer wall of the thumb wheel, and grooves 32 are arranged on the blades. The poking wheel and the arc surface on the guide block are coaxially arranged, and the edge of the blade is contacted with the arc surface. The rotation directions of the two thumb wheels are opposite, wherein the left thumb wheel rotates clockwise, and the right thumb wheel rotates anticlockwise.

As shown in fig. 2 and 7, a water pipe 2 is arranged on the inner side of the shell, the lower part of the water pipe is vertically arranged and is arranged in the middle of the shell, the upper part of the water pipe is arranged along the inner wall of the shell, and the upper part and the lower part of the water pipe are in smooth transition. The bottom of the water pipe is provided with a spray head 21 which is a conical structure with a small upper end and a large lower end, water in the water pipe is sprayed out through the spray head, then the water flows to the left side and the right side, and the water 7 can be stirred when the stirring wheel rotates, so that the water at the bottom of the shell is pushed upwards. A water outlet 14 is arranged on the side wall of the upper part of the shell, and a filter screen is arranged in the water outlet. Water enters the shell through the water pipe and then flows out of the water outlet. After the coal is added into the shell, the gangue with high density sinks to the bottom of the shell, and the coal with relatively low density is placed on the upper part of the shell under the action of water flow.

And a picking unit is arranged at the top of the shell, and the coal on the upper layer of the water is taken out through the picking unit. As shown in fig. 3 to 7, the picking unit comprises a fixed arm 4, a rotating shaft 41 rotatably mounted at the lower part of the fixed arm, vertical beams 5 fixed at both ends of the rotating shaft, and a coal basket 6 arranged at the first end of the vertical beams, wherein the fixed arm is relatively and fixedly connected with the casing. A driving mechanism for driving the rotating shaft to rotate is disposed in the inner cavity of the fixing arm, and as shown in fig. 6, the driving mechanism includes a driven gear 42 fixed on the rotating shaft, a driving gear 43 engaged with the driven gear, and a motor 44 disposed on the side wall of the fixing arm and driving the driving gear. The vertical beam is of a hollow structure, a fixed plate 51 is arranged in an inner cavity of the vertical beam, a telescopic oil cylinder 52 is fixed on the fixed plate, a push plate 53 is fixed on a piston rod of the telescopic oil cylinder, a telescopic arm 54 is fixed on the push plate, and the telescopic arm is connected with the vertical beam in a sliding mode. A boss 55 is arranged at one end of the telescopic arm far away from the push plate, and when the piston rod of the telescopic oil cylinder is completely retracted, the boss is contacted with the first end of the vertical beam. The left side and the right side of the vertical beam are provided with coal baskets 6 which are in a flat H-shaped structure. The first end of coal basket and the left and right side wall fixed connection of flexible arm, flexible arm this moment is arranged in the first end of coal basket. The bottom of the second end of the coal basket is hinged with a support plate 61 through a hinge shaft 62, lug plates 63 are fixed in the middle of the support plate and the coal basket, and two swing oil cylinders 64 are arranged between the lug plates on the support plate and the lug plates in the middle of the coal basket. After the piston rod of the swing oil cylinder retracts completely, the supporting plate is vertically arranged with the middle part of the coal basket. After the piston rod of the swing oil cylinder extends out, the supporting plate and the middle part of the coal basket form an obtuse included angle.

When the coal basket is used, the rotating shaft rotates under the action of the driving mechanism, the telescopic oil cylinder piston rod extends out when the rotating shaft rotates to drive the vertical beam to rotate in the vertical surface, and an obtuse included angle is formed between the middle part of the coal basket and the supporting plate. After the coal basket stretches into the water, an included angle between the supporting plate and the middle part of the coal basket is gradually reduced under the action of the swing oil cylinder, and the coal on the water layer is shoveled through the coal basket at the moment. The rotating shaft continues to rotate, and the piston rod of the telescopic oil cylinder retracts, so that the coal basket gradually moves out of the shell. After the coal basket moves out of the shell, the piston rod of the telescopic oil cylinder extends out and the piston rod of the swing oil cylinder extends out, and then coal in the coal basket is poured out.
