Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a freight vehicle equipped with a conveyor device, and more specifically, the present invention relates to a freight vehicle equipped with a conveyor device. This relates to a freight vehicle that can be used and cleaned.

[Prior art]

For freight cars that carry cargo boxes such as containers and tanks to transport irregularly shaped materials such as powder and granules, a conveyor device is installed on the floor of the cargo box to facilitate the unloading of the transported materials. will be installed. BACKGROUND OF THE INVENTION Recently, flat conveyors are often used as conveyor devices for storing and moving powder and granular materials, so that they can also transport fixed-sized objects and improve the efficiency of transportation.

By the way, when such a conveyor device moves a loaded object, a certain amount of clearance is ensured so that the lower part of the inner wall of the container and the side part of the conveyor do not come into contact with each other. Therefore, when loading or unloading granules, it is inevitable that some granules will spill from the sides of the conveyor through the gaps onto the floor of the container. Even when the conveyor is constructed of a large number of slat members extending in the width direction of the conveyor, if there are gaps between the slat members, a portion of the conveyed objects may fall through the gaps. Spilled powder and granules can no longer be carried out using a conveyor; once they have accumulated to a certain extent on the floor, they can be scraped out separately from the opening at the bottom of the container, or sucked up by inserting a suction device into the side of the conveyor. It must be removed by doing something like this.

[Problem that the invention seeks to solve]

As mentioned above, objects that fall on the floor of the container enter the sides and bottom of the conveyor. During transportation, they are scattered at locations where transmission devices for driving the conveyor, support devices for suppressing deflection of the conveyor, etc. are installed. Therefore, even if the scraping rod is inserted through the opening provided at the bottom of the container, it is necessary to weave between various devices and operate it back and forth and left and right, which is time-consuming. Moreover, there are limits to the range and amount that can be scraped out. Although the use of a suction device considerably reduces the labor required by the operator, there are problems with its operability, as the suction duct must be placed inside the container or crawled around the vehicle. Also,
Due to the arrangement of the drive device, there are shadow areas that are difficult to reach for the suction pipe. If the object to be transported has a shape or size that prevents suction, cleaning in this manner is also impossible.

The present invention has been made in view of the above-mentioned problems, and its purpose is to make it possible to easily, quickly and widely remove transported goods that have fallen or spilled onto the floor of a container by using the movement of a conveyor, while also making cleaning easier. To provide a freight car with a conveyor device, in which a cleaning tool can be removed when unnecessary, and the operation of the conveyor is not obstructed.

[Means for solving problems]

The features of the freight vehicle with a conveyor device of the present invention are as follows.
The explanation is as follows with reference to the drawings. A cargo box is provided on the vehicle body, and the front and rear sprocket 6 [second
Refer to figure] A freight car is equipped with a conveyor 3 moved by a chain 7 stretched between them, on the floor of the cargo box 2, and the conveyor 3 is arranged so as to extend in the width direction of the vehicle.
A large number of slat members 4 constituting the cargo box are arranged endlessly in the front-rear direction, and at least one of the slat members 4 is formed with a plurality of internal threads 18 in the vehicle width direction to clean the floor surface of the cargo box. A brush device 19 is removable, and a discharge port 28 (see FIG. 6) is provided on the floor of the cargo box 2 so that it can be opened and closed.

[Effect]

While the object is placed on the conveyor 3 and transferred, a screw for fitting a blind cover is screwed into the female threaded portion 18 formed in the slat member 4 so that its head does not come out. Therefore, the upper surface of the slat member 4 is smooth, and irregular-shaped objects such as powder or granular materials or regular-shaped objects mounted on pallets can be loaded into the cargo box or moved to the rear for unloading. Move to. on the other hand,
The conveyed object spills or falls between the slats 4 or from the sides of the slats 4. When loading or unloading, remove the screw screwed into the female threaded portion 18, and remove the screw threaded into the female threaded portion 18.
Attach the brush device 19 to. Since the female threaded portion 18 is provided on at least one of the many slat members 4, if the female threaded portion 18 is provided on the top surface of the conveyor 3, the threaded portion 18 is immediately inserted into the conveyor 3, and if it has gone around the bottom surface, the threaded portion 18 is provided on the conveyor 3 until it appears on the top surface. Turn and attach. When the conveyor 3 is moved, the brush device 19 moves together with the slat member 4 and moves to the lower side. The tip of the brush comes into contact with the floor surface of the cargo box, and as the conveyor 3 moves, the brush device 19 moves on the floor surface of the cargo box. During this process, the spilled material on the floor is swept up with a brush and brought to the front or back of the floor. The collected objects can be discharged by opening an outlet 28 provided in the floor. If there is a large amount of spillage, continue to move conveyor 3,
Sweep the floor surface many times with the brush device 19. The brush device 19 is moved by the movement of the conveyor 3, and discharge from the cargo box is automatically performed when the discharge port 28 is left open. When cleaning is completed, the slat member 4 to which the brush device 19 is attached is turned upward and the brush device 19 is removed. Then, by screwing the screw into the female threaded portion 18, it can be used as a conveyor.

〔Effect of the invention〕

At least one of the slat members arranged to extend in the vehicle width direction and connected endlessly in the longitudinal direction
The book has multiple internal threads in the vehicle width direction, a brush device that cleans the floor of the cargo box can be attached and removed, and a discharge port is provided on the floor of the cargo box that can be opened and closed. Therefore, it is possible to sweep up spills in a narrow space where it is difficult for an operator to clean. Furthermore, the movement of the conveyor can be used to easily and quickly remove a wide area. On the other hand, when cleaning is not required, the brush device can be removed so as not to interfere with the operation of the conveyor.

〔Example〕

Hereinafter, the present invention will be explained in detail based on examples thereof. FIG. 2 shows an example of a freight vehicle to which the present invention is applied, in which a container 2, which is a cargo box, is provided on a vehicle body 1, and a conveyor 3 is installed on the floor of the container 2. The conveyor 3 has a flat surface and is capable of transporting not only regular objects but also irregularly shaped objects such as powder and granules and wood chips. In this example, a conveyor 3 consisting of a large number of slat members 4 and a shielding member 5 that fills the gaps between them as shown in FIG. The chain links 8 are fixed to each slat member 4 to form an endless conveyor. As shown in FIG. 4, this conveyor 3 vertically surrounds girder members 9 arranged on the left and right sides at the bottom of the container 2, and the upper side, where the weight of the transported object acts, is supported by a rail 10 installed on the girder members 9. be done.

The lower part of the inner wall 11 of the container 2 is composed of a side plate 12, and a hanging part 14 extending toward the conveyor 3 is formed on the side of the transported object 13 to prevent the transported object 13 from easily falling off. . Here, to briefly explain the drive structure of the conveyor 3, a slat member 4 having a box-shaped cross section and extending in the left-right direction is attached to a bracket 15 fixed to a chain link 8a inside the chain 7 by bolts 1.
6, and the upper side of the conveyor moves forward when loading and backward when unloading by the rotation of the motor 17 (see Figure 2). Note that the slat members 4 are made of drawn aluminum, and as shown in FIG. 3, the inner sides are close to each other at the front and rear ends where the sprocket 6 is located, so a gap is provided to prevent mutual interference. ing. If the gap remains as it is, it will be impossible to transport fine irregular-shaped objects such as powder or granules, so the above-mentioned shielding member 5 of the fit-in type made of vinyl chloride or the like is adopted, and its deformation is used to prevent the return. Allows for bending.

Such a conveyor 3 is provided with a brush device for cleaning the floor surface of the container, as shown in FIG. To explain in detail with reference to FIG. 1, at least one of the slat members 4 is formed with a plurality of internal threads 18 in the vehicle width direction, and a brush device 19 for cleaning the floor surface of the container can be detachably attached. be.
The brush device 19 consists of an L-shaped member 20, a brush 21, and a holding fitting 22 that holds the brush 21 so as to sandwich the upper part of the L-shaped member 20, and the holding fitting 22 is fixed by a rivet 23. The L-shaped member 20 has a hole 24 for fixing it to the slat member 4, through which a bolt 25 screwed into the female threaded portion 18 described above is inserted. Therefore, the brush device 19 is fixed with the bolt 25,
Also, if you loosen and remove the bolt 25, the brush device 19
It has become possible to remove the The height of the brush device 19 is such that when the conveyor 3 rotates downward, the brush 21 sweeps the floor surface 2a of the container 2 as shown in FIG. etc., are appropriately selected depending on the arrangement of the conveyor drive mechanism, support mechanism, etc. on the floor of the container 2 and the objects to be transported. The bolt 25 mentioned above is screwed into the slat member 4, and in order to increase the amount of screw engagement, in this example, it is fixed to the slat member 4 by forming a retaining protrusion 26 by a simple pulling operation. A screw hole body 27 that can be used is employed.

On the other hand, a discharge port 28 is provided in the floor of the container 2 so as to be openable and closable. In the illustration, one is provided at the rear, rotates around a hinge 29, and can be kept closed by a screw 30.
Note that the discharge port 28 may be placed at the front, or may be placed at the front and back. Depending on the vehicle, it may be possible to discharge the spilled material from a location where it is easy to collect it, such as the lower center of the container.

The operation of the conveyor 3 configured in this way will be explained next. When attaching the brush device 19 to the conveyor 3, the slat member 4 having the female threaded portion 18 is moved so as to be on the top surface of the conveyor 3. A slat member 4 provided with such a female threaded portion 18
If they are provided every half circumference of the conveyor 3 or are provided in three or more places, one of them will be located on the top surface, and there is no need to move the conveyor 3 one by one to attach the brush device 19. . The countersunk screw 31 shown in FIG. 7 screwed into the female threaded portion 18 is removed, and the L-shaped member 20 of the brush device 19 is placed on the slat member 4. Female thread part 1
8 and the hole 24, insert the bolt 25, and screw the brush 21 into an upright state. When the discharge port 28 on the floor of the container 2 is opened and the motor 17 is driven, the brush device 19 moves together with the slat member 4, and the brush 21 sweeps the floor surface 2a. The materials collected by the brush 21, such as powder and granules, are dropped to the outside from the discharge port 28.
As long as the brush 21 continues to move, the floor surface 2a will be cleaned. When the brush 21 is attached to the L-shaped member 20 so as to extend in the width direction of the container 2,
Cleaning of the entire surface is completed in just a few operations. Outlet 28
For example, if the position is in the front, the sweeping direction may be changed by rotating the motor 17 in the opposite direction.

After cleaning, with the slat member 4 to which the brush device 19 is fixed facing upward, remove the bolt 25 and insert the countersunk screw 31 (see Fig. 7), and then remove the slat member 4.
Close the female threaded portion 18 on the top surface. Nothing protrudes from the upper surface of the conveyor 3, so that there is no hindrance to the movement of fixed-sized objects and irregular-shaped objects. Note that the brush device 19 is connected to the conveyor 3.
In order to attach the conveyor 3 to the slat member 4, it is preferable that a highly rigid member corresponding to the slat member 4 be connected in an endless manner. However, since the shielding member 5 in the above-described example merely fills the gap between the slat members 4, the present invention can be applied without the shielding member 5. By the way,
It is sufficient that the structure of the brush device 19 is compatible with the shape of the slat member to which it is attached, and the above-mentioned bolts or thumbscrews may be used as fastening members for fixing.
