Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder discharge device for a powder transport vehicle.

In general, in powder and granule transport vehicles, and in particular in screw-type powder and granule transport vehicles, a first transport cylinder that communicates with the tank is rotatably installed at the rear of a powder storage tank, and a second transport cylinder is installed above the first transport cylinder. By connecting the conveying tubes so that they can be raised and lowered, and by rotating and raising and lowering the first conveying tube and the second conveying tube, the powder and granular material is introduced into the upper part of the silo installed on the ground through the opening of the tip of the second conveying tube. It's becoming like that.

However, with the above structure, once the vehicle is stopped, if the silo is not located on the circumference with the radius of the length up to the opening of the second conveyor tube, the second conveyor tube must be raised or lowered or the vehicle must be moved. Therefore, in the former case, the opening of the second conveying cylinder and the silo were separated and the powder particles were scattered around, and in the latter case, it was very troublesome to adjust the stop position.

The present invention is intended to solve the above-mentioned problems, and an embodiment thereof will be described below with reference to the drawings. Reference numeral 1 denotes a powder storage tank mounted on a vehicle body 2, and the tank 1 faces downward and has left and right sides. The sides are tapered,
Screw conveyor 3 installed in the longitudinal direction of the bottom
The powder and granules stored in the
It's designed to lead you up to the point.

Reference numeral 5 denotes a powder discharge device that guides the powder and granules guided to the discharge section 4 to a silo (not shown) installed on the ground. - A transport cylinder 9 consisting of a second transport cylinder 8 and an auxiliary cylinder 1 provided at the tip of the transport cylinder 9
It consists of 0.

The first conveying cylinder 7 is erected at the rear of the tantalum 1, and has a structure in which the lower end is connected to the tantalum discharge section 4 and the upper part is supported so as to be rotatable. A base portion of a second conveying tube 8 is connected to the upper end of the first conveying tube 7, and the second conveying tube 8 is connected to the first conveying tube 7.
It is designed to be able to rise and fall using a hydraulic cylinder 11 installed at the top.

An opening 12 extending in the longitudinal direction is provided on the lower surface of the tip of the second conveying tube 8, and an auxiliary tube 10 for blocking the opening 12 is attached to the outer periphery of the tip so as to be slidable in the longitudinal direction. It has been done. A discharge port 13 having an opening area sufficiently smaller than the opening area of the opening 12 is formed on the lower surface of the auxiliary cylinder 10, and the discharge port 13 is always connected to a portion of the opening 12 regardless of the sliding of the auxiliary cylinder 10. It is connected to the department.

Reference numeral 14 denotes a hydraulic cylinder for sliding the auxiliary cylinder 10 in the longitudinal direction, and both ends of the hydraulic cylinder 14 are pivotally supported by the second conveyance cylinder 8 and the auxiliary cylinder 10 via brackets 15, 15, respectively.

Reference numeral 16 denotes a stopper provided on the outer periphery of the second conveying cylinder 8, and the stopper 16 is for preventing the discharge port 13 of the auxiliary cylinder 10 from coming off from the opening 12. In the embodiment, the auxiliary cylinder is slid by a hydraulic cylinder, but the same effect can be obtained even if the sliding movement is performed by mechanical means using a wire or the like.

Next, the operation of the present invention will be explained with the above-mentioned configuration. First, the vehicle is stopped at a position close to the silo, the first conveying cylinder 7 and the second conveying cylinder 8 are rotated and raised, and the discharge port 13 is connected to the silo. Match.
After that, the screw conveyor inside Tanta 1,
If the transport cylinder 7 and the second transport cylinder 8 are activated, the tanta 1
The powder inside can be transferred to a silo.

At that time, if the discharge port 13 does not align with the silo only by turning and undulating the first conveyance cylinder 7 and the second conveyance cylinder 8, the hydraulic cylinder 14 is extended and the discharge port 13 is moved from the solid line position in FIG. 2 to one point. By appropriately moving the discharge port 13 to the chain line position, the discharge port 13 can be aligned with the silo without moving the vehicle, and the opening 12 has an opening area that can sufficiently cover the sliding range of the discharge port 13. Therefore, the outlet 13 is always in communication with the opening 12, and the powder can be reliably guided to the silo.

As described above, the present invention provides an opening with a large opening area extending in the longitudinal direction on the lower surface of the tip of the conveying cylinder, and further includes an auxiliary cylinder that blocks the opening and has a discharge port that communicates with a part of the opening. It is movable, making it easy to align the discharge port to the silo, and eliminating the need for powder and granules to scatter around and the need to move the vehicle multiple times, as was the case in the past.
