SUMMARY OF THE INVENTION A conventional powder and granular material transport vehicle 1
In this case, as described above, the granular material P in the tank 2 is aerated with pressurized air, and the powder P is caused to flow down along the sliding plate 3 inclined downward from the front, rear, left, and right to the center. The gas was discharged from the discharge pipe 7 opened at the center of the lower part to the silo 9 or the like by using only the pressure difference between the inside and outside of the tank 2. Therefore, such a conventional granular material transport vehicle 1
In addition to the above, the sliding plate 3 is not only tilted largely down from the left and right toward the center (the center in the short direction) as described above, but also the sliding plate 3 and the bottom of the tank 2 are centered from the front and rear (the center in the longitudinal direction) It was necessary to form a special shape that was greatly inclined downward at the inclination angle α.

[0005] Therefore, such a conventional granular material transport vehicle 1
Then, the following problems were pointed out. First, there was a problem in terms of manufacturing cost. That is, since the slide plate 3 and the bottom of the tank 2 have a special shape which is greatly inclined downward from the front and rear to the center in order to cause the powder P to flow down, it is not easy to manufacture them. It has been pointed out that the manufacturing cost is increased and the cost is increased, for example, because it takes a lot of man-hours for assembling and hinders the automation of manufacturing.

[0006] Second, there is a problem in terms of volumetric efficiency. That is, since the slide plate 3 and the bottom of the tank 2 are inclined downward greatly from the front and rear toward the center in this way, a space is required under the bottom of the tank 2 to secure the inclination at the front and rear parts other than the center, It was pointed out that the dead space in terms of space and area was large, and the volume in the tank 2 for loading the granular material P had to be reduced by the dead space, resulting in wastefulness and poor volumetric efficiency. .

The present invention has been made in view of such circumstances, and has a structure in which an air supply pipe and a discharge pipe are arranged side by side below a discharge port between left and right slide plates, and the powder loaded in the tank is thus provided.

In addition, the discharge pipe has a slit-shaped opening formed in the longitudinal direction in opposition to a large number of holes at the outlet of the air supply pipe, and can be connected to an external silo or another receiving pipe. The granular material loaded in the tank flows in from the opening together with pressurized air from a number of holes in the outlet of the air supply pipe, and is discharged to the receiving pipe.

Next, claim 2 is as follows. That is, in the powder and grain carrier according to the above-described powdery and particulate carrier, a large number of holes at an outlet portion of the air supply pipe are provided in the discharge pipe in the discharge flow direction of the powder and grain.

The granular material transport vehicle 12 is also referred to as a bulk vehicle, and transports cement, flour, and other granular materials P by loading them in a dispersed state inside. As the granules P, carbon, sand, rice, other grains, chemical products, chemicals, and the like can be considered in addition to the above. The granular material transport vehicle 12 is disposed on a straight cylindrical tank 13 having a closed front and rear portion, and disposed on both lower sides in the tank 13 over the entire length in the longitudinal direction, and is inclined downward toward the center. Left and right sliding plates 14,
A central discharge port 15 formed in the longitudinal direction interposed between the slide plates 14, and a straight air supply pipe 16 and a discharge pipe 17 below the discharge port 15, which are arranged side by side at intervals. And In the illustrated example, each of them has a linear shape and is arranged horizontally without tilting further back and forth, that is, arranged in parallel with the road surface.

More specifically, first, a tank 13 in which the powders P are loaded is mounted on a chassis via a receiving stand or the like, and is made of aluminum, stainless steel, or other metal one-tank type. Is closed and has a substantially cylindrical shape with the same diameter (see FIG. 1 (1), each figure in FIG. 2, etc.). , At least one of the outer shape and the inner shape of the tank 13. At the top of the tank 13, a plurality of manholes for loading the granular material P are provided along the longitudinal direction (not shown), and the manhole includes an opening and a lid. Further, one end of an air introduction pipe (not shown) is connected to the tank 13, and the other end of the air introduction pipe is connected to a vehicle-mounted or external-side supply source of compressed air such as a compressor. It has become so.

Next, the left and right sliding plates 14, which are also referred to as a fluidized plate or an inclined plate, have a long plate shape and are disposed on the left and right sides of the lower portion in the tank 13 over the entire length in the longitudinal direction. It gradually descends from left and right toward the center (center in the short direction) (FIG. 1 (1), FIG. 2 (3),
(See FIG. 4D, FIG. 3A and FIG. 3C). In this way, the left and right sliding plates 14 are inclined symmetrically downward so as to move away from each other toward the upper side and approach toward the lower side, and there is an appropriate interval between the lower edges, and this interval is the discharge port 15. . That is, the discharge port 15 is interposed between the lower end edges of the left and right sliding plates 14, and is formed linearly in the longitudinal direction at the lower portion in the tank 13 at the center (the center in the short direction).

An air supply pipe 16 and a discharge pipe 17 are arranged directly below the discharge port 15. The air supply pipe 16 and the discharge pipe 17 have a cylindrical shape and are linearly arranged in the longitudinal direction of the lower part in the tank 13 corresponding to the discharge port 15, and the upper ends thereof are directly or interposed in the discharge port 15. They are arranged so as to be substantially closed under the discharge port 15 while being in contact with each other via a member, and there is a slight space between them (FIGS. 1 and 2 (3)). , (4), and each figure in FIG. 3).

First, the air supply pipe 16 is connectable to a supply source of pressurized air, and has an outflow portion 19 in which a number of holes 18 are formed in the longitudinal direction so as to face the discharge pipe 17. That is, the other end of the air supply pipe 16 is connected to a supply source of pressurized air on the vehicle or outside such as a compressor, and the outflow portion 19 is connected to the discharge pipe 17 side in the illustrated example. A plurality of holes 18 are formed at appropriate intervals along the longitudinal direction, and each of the holes 18 is arranged toward the opening 20 of the discharge pipe 17. (See FIG. 1 (2), FIG. 3 (2), etc.).

Next, the discharge pipe 17 has a slit-shaped opening 20 formed in the longitudinal direction, facing the multiple holes 18 of the outflow portion 19 of the air supply pipe 16, and has the other end connected to the outside. It can be connected to the silo 9 and other receiving pipes 8 (see FIG. 1 (3), FIG. 3 (2), FIG. 4 (2), etc.). The opening 20 is formed on a side surface of the discharge pipe 17,
In the illustrated example, the shape is a single linear slit,
It is also conceivable to form two or three parts separately.
The receiving pipe 8 is formed of a pipe or a hose attached to an external silo 9 or the like. Then, the granular material P loaded in the tank 13 flows into the discharge pipe 17 from the opening 20 together with the pressurized air from the many holes 18 of the outlet 19 of the air supply pipe 16, and It flows through the inside to the other end, and is discharged to the receiving pipe 8 and the silo 9.

In the illustrated example, a large number of holes 18 in the outlet 19 of the air supply pipe 16 are arranged so as to be inclined toward the discharge flow direction of the granular material P in the discharge pipe 17 and pressurized air. The granular material P flows into the discharge pipe 17 from the opening 20 substantially along the discharge flow direction (see FIG. 4A). That is, the large number of holes 18 of the outflow portion 19 of the air supply pipe 16 are arranged toward the opening 20 of the discharge pipe 17, and the vertical position thereof coincides with the opening 20 as in the illustrated example. Even if there is, the direction in the left-right direction is not perpendicular to the linear opening 20, and it is on the discharge flow direction side of the granular material P in the discharge pipe 17 (on the side opposite to the cab 10 in the illustrated example), It is formed to be inclined by the inclination angle β.

Further, in the illustrated example, the opening 20 of the discharge pipe 17 is formed on the bottom side of the discharge pipe 17 so that the pressurized air and the granular material P flow into the bottom of the discharge pipe 17. (See FIG. 1 (3), FIG. 3 (2), etc.).
That is, the opening 20 is formed at the bottom of the side surface of the discharge pipe 17, and pressurized air from the air supply pipe 16 and the tank 1.
The powder P from 3 flows into the bottom of the discharge pipe 17 reliably.

The air supply pipe 16 and the discharge pipe 17
Can have various structures other than the illustrated examples described above. For example, as shown in each drawing of FIG.
Although there is an interval between the tube 6 and the discharge pipe 17, the lower portions of the two are integrally connected by an intermediary plate 21.
An outflow portion 19 provided with a number of holes 18 on the side of the air supply pipe 16 and an opening 20 on the side of the discharge pipe 17 may be provided above.

In the first example shown in FIG. 5A, the interposition plate 21 has a linear flat plate shape, and is horizontally connected to the bottoms of the air supply pipe 16 and the discharge pipe 17 respectively. The bottom plate of the tank 13 is in contact with the lower surface thereof. In the second example shown in FIG. 5 (2), the interposition plate 21 is in the form of a straight flat plate, and is inclined between the air supply pipe 16 side and the discharge pipe 17 side, and connected between them. Has been established. Further, in the third example shown in FIG. 5C, the interposition plate 21 has a concave curved surface, and is connected to the bottoms of the air supply pipe 16 and the discharge pipe 17 respectively. Therefore, in the first example shown in FIG. 5A, the pressurized air is blown out horizontally from the air supply pipe 16 to the discharge space 17 while being guided by the intermediary plate 21 and flows therethrough. In the second example of FIG. 2B, the pressurized air flows from the air supply pipe 16 side to the discharge pipe 17 side so as to blow down while being guided by the intermediary plate 21, and the pressurized air flows between the two. The distance is short, and in the third example of FIG. 5C, the pressurized air flows from the air supply pipe 16 side to the discharge pipe 17 so as to be blown up while being guided by the intermediary plate 21.

The present invention has been described above. Then, it becomes as follows. In this granular material transport vehicle 12, the granular material P loaded and transported in the tank 13 is transported.
Is discharged as follows. That is, since the pressurized air is supplied from the supply source to the air supply pipe 16 and is blown out from the many holes 18 of the outlet 19 of the air supply pipe 16, first,
The powder P near the discharge port 15 flows into the discharge pipe 17 from the opening 20 while being mixed with such pressurized air (see FIG. 3 (2)). In addition, when the granular material P has already accumulated in the discharge pipe 17, the granular material P is caused to flow toward the receiving pipe 8. After that, the granular materials P loaded in the tank 13 sequentially flow down to the lower portion of the tank 13 along the left and right sliding plates 14, drop through the discharge port 15, and then fall into the air supply pipe 16. Outflow part 1
9 are mixed with the pressurized air blown out from the large number of holes 18, aerated and fluidized, and both flow into the discharge pipe 17 from the opening 20 (see each figure in FIG. 3). Then, it flows through the discharge pipe 17 and is discharged to the outside silo 9 and the like via the receiving pipe 8 while utilizing the pressure difference between the inside and outside of the tank 13 due to the pressurized air (see FIG. 4 (2)). ). In the illustrated example, since the discharge pipe 17 has a cylindrical shape, the pressurized air and the granular material P that have flowed in by aeration are:
In the discharge pipe 17, a vortex is formed along the inner surface of the pipe, and the vortex flows extremely smoothly through the discharge pipe 17 to be discharged.

In addition, in addition to the above, in the granular material transport vehicle 12, an air introduction pipe (not shown) of pressurized air is separately connected to the tank 13 as described above, and the sliding plate 14 is provided.
The powder P is discharged while using the pressurized air from the air inlet pipe connected to the upper level. That is, pressurized air is introduced into the tank 13 by this air introduction pipe, blown into the loaded granular material P, mixed, aerated, and fluidized. The powder P is discharged from the discharge pipe 17 and the receiving pipe 8 while utilizing the pressure difference. In addition, in FIG. 3 (1) and FIG. 4 (2), A indicates the internal pressure of the tank 13 serving as the inside, and B indicates the internal pressure of the silo 9 serving as the outside.

By the way, in this granular material transport vehicle 12,
A discharge port 15 is formed over the entire length between the lower slide plates 14 in the tank 13, and an air supply pipe 16 is formed below the discharge port 15.
And a discharge pipe 17 are arranged side by side, and the powder P is discharged using the flow of pressurized air between the two. Therefore, the sliding plate 14 may be inclined downward only from the left and right to the center (the center in the short direction) to cause the powder P to flow down from the left and right to the center. 6 and 7, the sliding plate 3 and the bottom of the tank 2 are tilted further toward the center (the center in the longitudinal direction) from the front and rear. There is no need to make a special shape that makes a large downward slope at α. That is, they have a linear shape (further horizontal in the illustrated example) before and after. Therefore,
The following is the first, second, third, and fourth aspects of the powder carrier 12.

First, the tank 13, the sliding plate 14,
The air supply pipe 16, the discharge pipe 17 and the like all have a linear shape in the longitudinal direction, that is, in the front and rear directions (see the respective drawings). As described above, the powder and granular material transport vehicle 12 has a straight and simple shape without the components being inclined in the middle, so that the production of the components is easy, and No assembly man-hours are required between them, and overall manufacturing automation is promoted. In addition, the canvas 6 in this type of conventional example shown in FIGS. 6 and 7 is not required, and the configuration is simplified from this aspect.

Second, the bottom of the tank 13 is also formed linearly in the longitudinal direction, that is, in the front-back direction, so that no space is required below the bottom of the tank 13 to ensure an inclination. Therefore, the granular material transport vehicle 12 has a spatial and
Small dead space in area
Can be made large in the tank 13 in which the container is loaded.

Third, in the illustrated example of the granular material transport vehicle 12, in addition to the above-described configuration, the outlet portion 1 of the air supply pipe 16 is provided.
The nine holes 18 are inclined by a predetermined inclination angle β (see FIG. 4A). Then, the pressurized air flows from the air supply pipe 16 side to the discharge pipe 17 at an inclination angle β, and the pressurized air and the granular material P flow into the discharge pipe 17 from the opening 20 substantially in the discharge flow direction. Since the water flows along the discharge pipe, such a flow flows through the discharge pipe 17 extremely smoothly and is discharged. Further, in the granular material transport vehicle 12 of the illustrated example, an opening 20 is formed on the bottom side of the discharge pipe 17 in addition to the above-described configuration (FIG. 3 (2), FIG. 5). Etc.). Then, pressurized air and powder P
Surely flows into the bottom of the discharge pipe 17 through such an opening 20, and the powder P is discharged from the discharge pipe 17 by such a flow.
Because they are all paid off without stagnation and stagnation at the bottom of the
Also from this surface, the gas flows extremely smoothly through the discharge pipe 17 and is discharged.

Fourth, in the granular material carrier 12 shown in the figure, the tank 13, the sliding plate 14 and the like are formed linearly forward and backward without being inclined in the middle, and furthermore, horizontally. That is, they are arranged parallel to the road surface. In contrast,
In the above-described prior-art granular material transport vehicle 1 of FIGS. 6 and 7, since these have a shape inclined downward from the front and rear toward the center in order to discharge the granular material P. However, there is a restriction that discharge must be carried out on horizontal roads and places before and after.
In No. 2, such a restriction is eliminated. That is, even if the road / place is inclined, the powder P can be discharged without any trouble.

[0031]

According to the present invention, as described above, the air supply pipe and the discharge pipe are arranged side by side below the discharge port between the left and right sliding plates, and are loaded into the tank. The following effects are exhibited by allowing the powdered particles to flow into the discharge pipe through the opening together with the pressurized air from the many holes at the outlet of the air supply pipe and discharge the same.

First, the manufacturing cost is excellent. In other words, this powder carrier is easy to manufacture, does not require assembling man-hours at the time of manufacture, and promotes automation of manufacturing.
Manufacturing costs are reduced.

Second, the volumetric efficiency is also improved. That is,
In this granular material transport vehicle, the spatial and area dead space below the bottom of the tank is small, and accordingly, the volume in the tank in which the granular material is loaded is increased, and the volume efficiency is improved.

Thirdly, the granular material carrier according to the second aspect of the present invention further includes a plurality of holes at the outlet of the air supply pipe which are inclined as predetermined. Since the opening is formed on the bottom side of the discharge pipe, the discharge of the granular material can be realized extremely smoothly. in this way,
The effects exhibited by the present invention, such as eliminating the problems existing in this type of conventional example, are remarkably large.
