Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a powdery or granular material consolidation prevention device applied to, for example, a powdery or granular material application vehicle.

(Prior Art) Conventionally, for example, Japanese Patent Laid-Open No. 61-24 has been used as a powder-dispersion vehicle.
2658 and JP-A-62-206106 are known.

As shown in FIGS. 1 and 2, the powder-dispersion vehicle 100 basically has an engine 101, a cooling mechanism 102 that cools the engine 101 with a cooling liquid, and a hopper 103 that stores the powder. A feeder 104 that is provided in the hopper 103 to transfer the granular material, and a metering rotor 105 that discharges the granular material from the feeder 104 by a predetermined amount.
The metering rotor 105 is used to disperse the powder and granules.

The engine 101 is provided on the vehicle body 107, drives the wheels 110 via the transmission 108 and the differential 109, and at the same time, transmits the transmission 108.
The feeder 104 is driven via a power takeoff device 111, a speed reducer 112, a torque limiter 113, and a sprocket chain 114 provided between the differential gear 109 and the differential 109.

However, such a powder-dispersion vehicle is often used in a cold region as well as using an antifreezing agent (crushed salt) as the powder.

In such a case, the powder or granules are cooled by the outside air through the hopper, so that they are solidified and the fluidity is deteriorated, so that they cannot be transferred by the feeder.

This is because the antifreezing agent which is a granular material starts to solidify at -6 ° C when the water content becomes 6%.

For this reason, in the past, solidification was prevented by applying mechanical force to the powder or granular material using a rod or the like, but the workability was very poor.

(Problems to be solved by the invention) In view of the above problems, the present invention was devised to solve this problem, and the purpose of the invention is to solidify the heating of the powder and granules. It is an object of the present invention to provide an apparatus for preventing the solidification of powder and granules for preventing the solidification.

(Means for Solving the Problem) The powdery / agglomerate solidification preventing device of the present invention is provided in an engine, a cooling mechanism for cooling the engine with a cooling liquid, a hopper for storing the powdery or granular material, and a hopper. The feeder for transferring the powder and granules, the circulation path provided in the hopper for circulating the cooling liquid of the cooling mechanism, and the cooling mechanism and the circulation path are connected so that the cooling liquid of the cooling mechanism circulates through the circulation path. There is a feature in that it consists of a connecting part.

(Operation) When the engine is started, the cooling liquid of the cooling mechanism is heated by the heat of combustion.

The heated cooling liquid circulates among the cooling mechanism, the connection path, and the circulation path.

At this time, the cooling liquid passing through the circulation path heats the granular material through the hopper.

When the powder or granules are heated, they do not solidify.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing a powder / particle spraying vehicle that employs a powder / particle solidification preventing device according to an embodiment of the present invention.

FIG. 2 is a vertical sectional rear view.

The powder / solid aggregation prevention device 1 includes an engine 101 and a cooling mechanism 1.
02, the hopper 103, the feeder 104, the circulation path 2, and the connection path 3 constitute a main part thereof.

The engine 101 is the main body of the powder / particle solidification prevention device 1.

In this example, the diesel engine is used and mounted on the vehicle body 107 of the powder-dispersion vehicle 100.

The cooling mechanism 102 cools the engine 101 with a cooling liquid.

In this example, a jacket 115 formed in the engine 101 and having an inlet and an outlet, a radiator 116 arranged in front of the engine 101 and having an inlet and an outlet, and an inlet of the jacket 115 and an outlet of the radiator 116 are connected. The connection passage 117, the cooling liquid (cooling water) filled therein, and the radiator 1 driven by the engine 101
And a fan 118 for cooling 16.

In the cooling mechanism 102, normally, the outlet of the jacket 115 and the inlet of the radiator 116 are also connected by a connection passage so that the cooling liquid circulates, but this connection passage is removed.

The hopper 103 stores the granular material.

In this example, it has a substantially V-shaped box shape, has an inlet at the top, an outlet at the rear, and a substantially mountain-shaped partition plate inside, and is provided on the vehicle body 107 of the powder-dispersion vehicle 100. There is.

The feeder 104 is provided in the hopper 103 to transfer the powder or granular material.

In this example, the screw feeder is used and the hopper 10
3 is provided in the lower part of the hopper 3 so that the powder or granular material in the hopper 103 is transferred to the outlet side.

The circulation path 2 is provided in the hopper 103.

In this example, a pipe is provided around the outer lower half of the outer wall forming the hopper 103 and provided with an inlet and an outlet, and the pipe is filled with a cooling liquid.

The connection path 3 connects the cooling mechanism 102 and the circulation path 2 so that the cooling liquid circulates through the circulation path 2.

In this example, the inlet of the circulation path 2 and the outlet of the jacket 115 are connected, and the outlet of the circulation path 2 and the radiator 116 are connected.
There is a hose that connects the inlets of, and these are filled with cooling liquid.

Next, the operation will be described based on such a configuration.

When the engine 101 is started, the cooling liquid in the jacket 115 is heated by the heat of combustion.

The heated cooling liquid is, as shown by the arrow in FIG. 1, jacket 115 → one connecting path 3 → circulating path 2 → other connecting path 3 → radiator 116 → connecting path 117 → jacket 11
It circulates like 5.

At this time, the cooling liquid passing through the circulation path 2 heats the granular material inside through the lower half of the outer wall of the hopper 103, especially the granular material transferred by the feeder 104.

When the granules are heated, they no longer unite.

Therefore, the granular material is smoothly transferred by the feeder 104.

In addition, although the powder / particle solidification preventing device 1 is applied to the powder / particle spraying vehicle 100 in the above-described embodiment, the powder / particle solidification preventing device 1 is not limited to this and may be applied to other devices, for example.

The cooling mechanism 102, in the previous embodiment, is a radiator 116.
However, the present invention is not limited to this and may be omitted, for example. In this case, the outlet of the circulation path 2 and the inlet of the jacket 115 are connected by the connection path 3.

Although the feeder 104 is a screw feeder in the above embodiment, the present invention is not limited to this, and may be a belt conveyor or the like.

Although the circulation path 2 is a pipe in the above embodiment, the circulation path 2 is not limited to this and may be, for example, a jacket.

Although the circulation path 2 is provided in the lower half of the outer wall of the hopper 103 in the above embodiment, the present invention is not limited to this and may be provided, for example, on the entire outer wall of the hopper 103.

Although the powdery or granular material was the antifreezing agent in the above-mentioned embodiments, the powdery or granular material is not limited to this, and may be, for example, another material.

(Effect of the Invention) As described above, according to the present invention, the following excellent effects can be achieved.

(1) Engine, cooling mechanism, hopper, feeder, circulation path,
Since it is composed of the connecting path, it is possible to prevent the solidification by heating the powder or granular material.

(2) Since the engine is used as a heat source, a dedicated heat source is not required.

(3) Since the circulation path also becomes a part of the cooling mechanism, the cooling efficiency of the engine is improved.
