Drawings

The following detailed description of embodiments of the invention is provided in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of a first embodiment of the present invention;

fig. 2 is a schematic structural diagram of a second embodiment of the present invention.

Detailed Description

The first embodiment is as follows: when the stemming 7 cannot be directly fed into the hydraulic clay gun 5 by the vertical blanking pipe 4 due to the limitation of field environmental factors, as shown in figure 1, a belt conveying system is additionally arranged between the hydraulic feeding system and the clay gun system,

when the hydraulic clay gun 5 needs to be charged with clay, an operator firstly puts the clay 7 into the clay hopper 2 by a travelling crane, then converts the hydraulic conversion module 15 to the clay charging side, the hydraulic station is started by the wireless controller 16 to work, at the moment, the travelling trolley 10 runs to the clay charging side along the track 11 under the driving of the travelling motor and the chain, when the specified position is reached, a baffle on the travelling trolley 10 is touched with the limit switch, and the limit switch acts to stop the travelling motor, then, the belt conveyor 8 is driven by the conveyor transmission motor 9, meanwhile, the hydraulic oil cylinder 3 pushes the clay 7 to the vertical blanking pipe 4 from the clay conveying piston cylinder 1 through the back-and-forth movement, the clay 7 falling from the vertical blanking pipe 4 falls onto the belt conveyor 8 and is sent into the hydraulic clay gun 5 through the belt conveyor 8. The design of the limiting block and the mechanical limiting block 13 limits the farthest stroke of the walking trolley 10, and prevents the walking trolley 10 from separating from the track 11. In addition, the dust excluding hood 14 that sets up establishes belt conveyor system and mud gun system cover in inside, and hydraulic cylinder 3, stemming transport piston barrel 1 and mud gun bucket 2 install in the top of dust excluding hood 14, can conveniently add stemming 7 through the driving.

Example two: when the field conditions are met, the vertical blanking pipe 4 can directly input the stemming 7 into the hydraulic clay gun 5. As shown in fig. 2, when the hydraulic clay gun 5 needs to load clay, an operator firstly puts the clay 7 into the clay hopper 2 by a travelling crane, then converts the hydraulic conversion module 15 to the clay loading side, starts the hydraulic station work by the wireless controller 16, at this time, the travelling trolley 10 runs to the clay loading side along the track 11 under the driving of the travelling motor and the chain, when the specified position is reached, a separation blade on the travelling trolley 10 touches the limit switch, the limit switch acts to stop the travelling motor, and then the belt conveyor 8 is driven by the conveyor transmission motor 9, and meanwhile, the hydraulic oil cylinder 3 pushes the clay 7 from the clay conveying piston cylinder 1 to the vertical blanking pipe 4 by reciprocating motion, the falling clay 7 in the vertical blanking pipe 4 directly passes through the clay gun mud loading port 6 and falls into the hydraulic clay gun 5.

The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments may be combined with each other into a new embodiment. The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
