FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

in the figure: a hoist 1; a fixed pulley 2; a first movable sheave 3; a bulk head 4; a balancing weight 5; an infrared sensor 6; a counterweight support 7; a dust collection pipe 8; a wire rope 9; a proximity switch 10; a dust collection cover 11; a second movable sheave 12; a base 13; a connecting rod 14.

Detailed Description

The present invention will be further described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, the lower limiting device of the bulk machine comprises a hoisting device, a bulk head 4 and the like, wherein the bulk head 4 is of a three-section telescopic structure, a dust collection cover 11 is mounted at the lower end of the bulk head 4, the dust collection cover 11 is communicated with a dust collection pipe 8, and a dust collector connector is arranged at the upper end of the dust collection pipe 8. The lifting of the bulk head 4 is driven by a winding device, the winding device comprises a winding engine 1, a fixed pulley 2, a first movable pulley 3, a steel wire rope 9 and the like, the three first movable pulleys 3 are arranged at the lower part of the lower section of the bulk head 4, the three fixed pulleys 2 are arranged on a rack above the bulk head 4, the winding engine 1 is arranged on a base 13 at the outer side of the upper section of the bulk head 4, and the first movable pulley 3, the fixed pulley 2 and the winding engine 1 are connected through the steel wire rope 9.

A second movable pulley 12 is arranged on a steel wire rope 9 between the winch 1 and the fixed pulley 2, a wheel shaft of the second movable pulley 12 is hinged with one end of a counterweight support 7, the counterweight support 7 is a straight rod or a welding component, the other end of the counterweight support 7 is hinged with an ear seat (not shown in the figure) through a pin shaft, and the ear seat is installed on a base 13. The axle of second movable pulley 12 installs vertical connecting rod 14, and the lower extreme installation balancing weight 5 of connecting rod 14, the weight of balancing weight 5 are 20 kilograms, and the below of balancing weight 5 is equipped with infrared inductor 6, and infrared inductor 6 installs in the frame of bulk machine. The upper section of the bulk head 4 is provided with a proximity switch 10, and the infrared sensor 6 and the proximity switch 10 are electrically connected with a control circuit of the windlass 1.

The working process of the embodiment is as follows: when a vehicle stops below the bulk head 4, an operator controls the winch 1 to operate through the handle, the bulk head 4 descends downwards to the bottom in the carriage, when the dust collection cover 11 touches the bottom of the carriage, the steel wire rope 9 loosens, the counterweight 5 begins to descend at the moment, when the counterweight 5 touches the infrared sensor 6, the winch 1 stops operating automatically, the steel wire rope 9 is tightened, the dust collection cover 11 is located at the optimal position height, materials are loaded through the bulk head 4, dust is collected by the dust collection cover 11 and conveyed into the dust collector through the dust collection pipe 8 to be dedusted in bulk, when the vehicle loading is finished, the operator controls the winch 1 to operate, the bulk head 4 ascends, the winch 1 stops operating automatically after touching the proximity switch 10, and the vehicle runs out of a bulk loading lane. The utility model discloses can adapt to the vehicle of co-altitude not, put the carriage bottom with the bulk head, then automatic shutdown descends, increases the dust collecting capacity of dust cage, improves dust removal effect.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
