Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a dual-purpose transport vehicle for powder and granular materials and general cargo. In other words, rice must be transported in bulk.

Powdered materials such as flour, other grains, sand, cement, etc.
The present invention relates to a highly versatile transport vehicle that can transport miscellaneous goods and other general cargo by transshipping them as appropriate.

"Conventional technology" Conventional vehicles for transporting powder, granular materials, etc. are as follows.

First of all, specially constructed transport vehicles such as bulk vehicles are generally widely used as transport vehicles specialized for powder and granular materials. This type of transport vehicle cannot transport general cargo.

Second, vehicles that carry both powder and granular materials and general cargo are also used. In this dual-purpose carrier, unloading when loaded with powder and granular material was performed as shown in FIGS. 11 and 12. In other words, one can hear both or one of the double-opening rear doors 2, which are installed at the rear end of the cargo compartment 1 loaded with powder and granular material A, and are also used for loading and unloading general cargo, and the vehicle chassis 3 can be opened. By tilting the cargo compartment 1 loaded on top backward, the powder and granular material A can be removed. M wholesale was being carried out.

Thirdly, as an improved version of such a general purpose transport vehicle, the 13th
As shown in the figure, a rear door 2 was provided with a discharge section 4 for discharging powder A at the lower center of the rear door 2.

``Problems to be Solved by the Invention'' By the way, the following problems have been pointed out with such conventional transport vehicles.

First, regarding the bulk vehicle etc. of the prior art example 1, the following is true.

In other words, because of the special structure of such a transport vehicle, it was not possible to transport general cargo other than the granular material A. Therefore, the scope of use is severely restricted, and in many cases, one-way transportation is performed, such as transporting powder or granules on the outward trip but leaving the return trip empty, resulting in extremely poor transportation efficiency.

Next, regarding the dual-purpose transport vehicle of Conventional Example 2, the details are as follows.

This transport vehicle is excellent at transporting general cargo, and can also transport powder and granular material A as appropriate.For example, it is possible to transfer general cargo to powder and granular material on the outbound and return trips. Although it was excellent in terms of efficiency, it had the following problems. In other words, as shown in Figures 11 and 12, the powder and granular material A is unloaded by opening the rear door 2, which is used for loading and unloading general cargo. The granular material A is discharged, and the unloaded granular material A is scattered over a wide area. Therefore, depending on the condition of the equipment on the receiving side, it may not be possible to unload the powder or granular material A within the designated receiving area, and it may be scattered around, causing the risk of contamination with foreign matter such as dirt and dust, making it virtually difficult to control the unloading. Sometimes it happened. Therefore, depending on the type of powder or granular material A, such as food, there may be some that are unsuitable for transportation by such a transport vehicle, making it difficult to transport the powder or granular material, which has become a problem.

This problem becomes particularly noticeable when unloading with both rear doors 2 open, as shown in FIG. 11. On the other hand, as shown in Fig. 12, when only one side of the rear door 2 is opened to unload cargo,
Although the range in which the particulate material A is scattered is somewhat narrowed, and this problem has been somewhat resolved, the following problem has been raised. That is,
It was not possible to unload all of the powder and granular material A naturally, and the powder and granular material A was stored in the cargo compartment 1 near the rear door 2 on the side that could not be opened.
There was a problem that '' remained. Furthermore, the entire transport vehicle
There is also a problem that the remaining powder particles may lean toward the A' side, and depending on the condition of the ground on which the vehicle is parked, there is a concern that an accident may occur.

Further, in the case of the dual-purpose transport vehicle provided with the discharge section 4 for powder and granular material A according to the conventional example 3, the procedure is as follows.

In this transport vehicle, as shown in FIG. 13, while the above-mentioned problem of scattering of the powder and granules A was solved, the problem of the remaining powder and granules A' remained unsolved. Therefore, as a countermeasure for residual powder A' in such a transport vehicle, first,
When transporting, a removable attachment member is attached around the discharge part 4 of the cargo hold 1 to form the part into a hopper shape or a trumpet shape. The bag was built into cargo hold 1, etc.

However, such attachment members are troublesome to handle and pose problems in terms of work efficiency, and since the bag body is formed in a hopper shape near the discharge section 4 of the cargo compartment 1 as described above, there is a gap between the bag body and the rear door 2. A large gap was created in the bag, making it difficult to hold the bag in place, making the part of the bag easily damaged and causing problems in durability.

In the conventional example, the above points were pointed out.

In view of these circumstances, the present invention has been made to solve the problems of the conventional example described above. It is an object of the present invention to propose a dual-purpose transport vehicle for powder and granular materials and general cargo, in which the loaded powder and granular materials can be unloaded reliably and easily by forming the vehicles so that they are inclined to approach each other.

"Means for Solving the Problems" The technical means of the present invention to achieve this objective are as follows.

This dual-purpose transport vehicle for powder, granular materials and general cargo has a box-bar shape and a cargo compartment mounted on a chassis that can be tilted rearward in the longitudinal direction. The cargo compartment has a loading section for granulated particles, and a rear door for general cargo which is provided at the rear end of the cargo compartment and has a center section and both sides and can be opened and closed.

A powder discharge section including a discharge port and a lid is provided at the lower center of the rear door.

In addition, both sides of this rear door are located between both side walls of the cargo compartment and the discharge section when closed, and have opposing inner surfaces that are sloped so that they approach each other toward the rear. .

"Function" Since the combined use vehicle for transporting powder and granular materials and general cargo according to the present invention is comprised of such means, it functions as follows.

First, loading and unloading of the prefecture transporting general cargo is done by opening the rear door.

Next, the powder and granular material is transported as follows.

Loading is done through the loading port by opening the lid of the loading section, which is placed on the top wall of the cargo hold.

The cargo is unloaded by opening the lid of the discharge section attached to the rear door and tilting the cargo compartment rearward on the vehicle chassis. Then, the powder and granules that had been accumulated in the output chamber are discharged from the discharge port by the own vehicle.

In this way, powder and granular materials and general cargo can be transshipped and transported as appropriate, and there is also an fJl exit section exclusively for powder and granular materials.
Since the powder and granules are discharged from the low and small discharge port, the powder and granules are not scattered around and are reliably unloaded to a predetermined receiving location.

Further, both sides of the rear door are located between the side walls of the cargo compartment and the discharge part of the rear door in the closed state, and have opposing inner surfaces formed at an angle so as to approach each other toward the rear. The tilted powder and granules in the cargo compartment are guided by this inner surface and flow naturally toward the outlet at the bottom of the center of the rear door, ensuring that all of the material leaves the outlet without leaving any residue. It is drained and unloaded.

As described above, powder and granular materials can be unloaded reliably and easily. In addition, since the inner surfaces of both sides of the rear door are sloped as mentioned above, even if a bag is used to store powder and granules in the cargo compartment, there will be no unnecessary voids, and the bag will be able to handle the cargo. Reliably kept indoors.

The open end surface of the rear end 7 is sealed. Furthermore, this rear door 2
In the illustrated example, it is attached to the rear end portion 7 of the cargo compartment 5 via a hinge portion 19 so as to be openable and closable.

A discharge section 20 for the granular material A is provided at the lower part of the central portion 17 of the rear door 16, and the discharge section 20 includes a discharge port 21 and an attached lid body 22.

This discharge part 20, especially its discharge port 21, is made of a relatively small part suitable for unloading the powder and granular material A, and in addition to a box shape projecting backward as shown in the figure, a part with almost no wall thickness, and various other shapes. is possible.

In addition, both sides 18.18 of the rear door 16 are located between the side walls 23.23 of the cargo compartment 5 and the discharge part 20 in the closed state, and are formed so as to be inclined toward each other by one side. It has an inner surface 24.2=1. The inclination angle θ of the inner surface 24 of both side portions 18 with respect to the inner surface of the center portion 17 is set to an angle that matches the general angle of repose and slip angle of the powder and granular material A loaded fi in the cargo compartment 5. Both sides 18 like this
The shape of the rear door 16 consisting of ゜ 18 and the center part 17,
The rear end 7 of the cargo compartment 5 is formed in a corresponding manner, and in the illustrated example, the planar cross-sectional shape of the rear end 7 is approximately trapezoidal, so that the rear end 7 can be sealed against the rear door 16. be done. Also, both sides 18. Although the central portions 17 each have a flat plate shape in the illustrated example, they may be formed into a normal arc shape or the like as appropriate.

Note that the rear door 16 has a central portion 17 and both side portions 18 and 18 that are integrally bent as shown in FIGS. 2 and 3, and a central portion 17 as shown in FIGS. and both sides 1

By inserting the engagement rods 28, 28.28 into the engagement holes 27, 27.27, respectively, which are provided in the rear end 7 of the cargo compartment 5 in correspondence with the above, the two are engaged. , so that the rear door 16 is locked to the rear end 7.

In FIGS. 1 and 2, 29 is a ladder, and this ladder 29 is used for climbing up and down the top wall 12 for opening/closing the loading section 13 and the like. Further, 3o is an intake part, and this intake part 3o is used for unloading the powder and granular material A from the discharge part 20,
This is to take in air from outside so that the inside of the cargo compartment 5 does not become a negative pressure.

This concludes the explanation of the configuration.

Next, the operation of this dual-purpose transport vehicle will be explained.

When used for transporting general cargo B, it will be as follows.

In other words, loading and unloading of general cargo B is done through rear door 1.
This is done from the rear end 7 of the cargo compartment 5 by opening 6.

When used for transporting powder or granular material A, it will be as follows.

Loading of the powder or granular material A is carried out through the loading port 14 after viewing the lid 15 of the loading section 13, and the lid 15 is then opened.

After arriving at the destination, unloading of the powder and granular material A is done through the rear door 16).
This is done by pulling the lid 22 of the J1m exit part 20 and driving the cylinder 10 to tilt the cargo compartment 5 upward and rearward on the chassis 6.

The powder and granular material A scattered in the cargo compartment 5 flows out from the discharge port 21 due to its own weight.

In this way, the granular material A and the general cargo B can be transported by transshipping as appropriate. For example, the granular material A can be transported on the outbound trip, and the general cargo B can be transported on the return trip. In addition, it is equipped with a discharge part 20 for the powder and granular material A, and the powder and granular material A is discharged little by little from a low and small discharge port 21, so that the powder and granular material A is not scattered around and is delivered to a predetermined receiving place etc. It will definitely be unloaded.

Here, both sides 18 of the rear door 16 are located between the side walls 23, 23 of the cargo compartment 5 and the discharge part 20, and are provided with opposing inner surfaces that are inclined so as to approach each other toward the rear.

4 and naturally flows toward the outlet 21 in the lower part of the central part 17 of the rear door 16.

All of the powder and granular material A is reliably discharged from the discharge port 21 and unloaded without any residual portion remaining in the cargo compartment 5.

In this way, the granular material A can be unloaded reliably and easily, and there is no need to install a special attachment section in the cargo compartment 5 each time the granular material A is transported.

A bag C is built into the cargo hold 5, and rice, flour, other edible grains, etc. that need to be transported hygienically are stored therein. This bag C is folded upward in the cargo compartment 5 when not in use. Now, as mentioned above, the inner surfaces 24 and 24 of both sides 18 and 18 of the rear door 16 are inclined, so when using this bag C, the bag C
The shape almost matches the shape of the corresponding part, so there is no large wasteful gap between the two. Therefore, the bag C is securely held on the rear door 16 and the like through a small gap, so that this part will not be damaged.

"Other Embodiments" FIGS. 6 and 7 show a second embodiment of the dual-purpose carrier according to the present invention.
