Description

  The present invention relates to a transport vehicle having a deep body luggage compartment.

  As a typical example of a transport vehicle, a dump truck that transports earth and sand is well known. In the dump truck, a granular material such as a wood chip or a plastic chip (hereinafter referred to as a bulk) having a specific gravity smaller than that of the earth and sand. When the material is transported, the load capacity is bulky, making it difficult to fully utilize the load capacity of the dump truck, which is very uneconomical and inefficient transport work. As means for solving the problem, for example, Patent Document 1 describes a structure of a transport vehicle including a cargo room (hereinafter referred to as a deep body cargo room) having a raised wall surface.

A transport vehicle according to the prior art will be described with reference to FIGS.
In FIG. 11, a transport vehicle 80 includes a driver's cab 83 at a front portion of a chassis 82 and a deep body luggage compartment 84 at an upper portion. The cargo compartment 84 has side plates 87 on the left and right sides, and floor plates (hereinafter referred to as slide floor plates) 85 that slide back and forth by a hydraulic cylinder 86 at the bottom. A push plate 88 is provided between the side plates 87 and 87. The push plate 88 is selected by a coupling device (not shown) between a state of being coupled to the slide floor plate 85 (state of Fa in the drawing) and a state of being coupled to the left and right side plates 87 and 87 (state of Fb in the drawing). It is possible.

  The operation of the above configuration will be described. First, in FIG. 12A, in the state where the push plate 88 is coupled to the slide floor plate 85 (in the state of Fa in the drawing), the slide floor plate 85 is indicated by the arrow X in the drawing by the hydraulic cylinder 86. If it is slid in the direction, the rear portions of the slide floor plate 85 and the load W project on the pit 91 by the stroke length of the hydraulic cylinder 86. Next, in FIG. 12B, in the state where the push plate 88 is coupled to the left and right side plates 87, 87 (the state of Fb in the drawing), the slide floor plate 85 is slid in the direction of arrow Y in the drawing by the hydraulic cylinder 86. Then, the rear portion W1 of the load W falls into the pit 91. In this manner, the operation shown in FIG. 12A and the operation shown in FIG. 12B are alternately repeated to unload the load W, whereby a large cargo chamber 84 is obtained. The load W can be unloaded without tilting the rearward.

Japanese Patent No. 30625568 (pages 2 to 3, FIGS. 1 to 9)

However, some problems described below remain in the configuration of the transport vehicle according to the above prior art.
(1) When loading a bulk material on the transport vehicle 80, in order to load the bulk material into the large deep body loading chamber 84 substantially uniformly without any deviation, the bulk material is placed at each position in the front-rear direction on the loading chamber 84. The material has to be thrown in substantially evenly. Therefore, when throwing with a fixed hopper whose installation position is fixed, it is necessary to always move the transport vehicle back and forth. It is required and the load on the driver is large. Moreover, if a moving hopper having a loading port movably provided is prepared, the equipment cost of the hopper increases.

(2) For the reason of (1) above, when loading a bulk material on the transport vehicle 80, the upper surface of the cargo compartment 84 is often in an open state without a cover, and as a result, for example, incineration When a bulk material containing powder such as ash is added, dust may rise and cause environmental pollution.

(3) As a means for preventing spillage of the load when the transport vehicle 80 travels, there is known a method of attaching an openable / closable simple cover on the upper surface of the cargo compartment 84, a so-called automatic opening / closing tilt, Airtightness is insufficient, so when a bulk material containing powder is loaded, loads such as powder and wood chips may be scattered by the wind and cause environmental pollution.

  The present invention has been made paying attention to the above-mentioned problems, and it is possible to load a bulk material containing powder into the cargo room without any deviation, and to prevent powder scattering during loading of the bulk material and during traveling. An object of the present invention is to provide a transport vehicle having a deep body cargo room.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a transport vehicle having a deep body cargo room, a slide floor plate slidably provided in a vehicle front-rear direction, fixed to a rear portion of the cargo compartment, A fixed floor plate provided so that a rear end portion of the slide floor plate slides and overlaps with each other in accordance with a front-rear slide, and the rear end portion of the slide floor plate is a rear end of the fixed floor plate when sliding backward It is configured so as not to protrude rearward.

  According to a second invention, in the transport vehicle according to the first invention, at least one of the sliding surfaces of the rear end portion of the slide floor plate and the fixed floor plate is configured by a slide member having a good sliding property. .

  According to a third invention, in the first invention, a closed bottom plate is provided at the bottom of the cargo compartment, and the slide floor plate is provided above the bottom plate.

  4th invention attaches the roof which has one or more hatches used as loading port of a load, such as a granular material, and a hatch cover which can be opened and closed to the upper surface of a loading room in a cart equipped with a deep body loading room It has a configuration.

  In a fifth aspect based on the fourth aspect, it is preferable that the roof is configured so as to be divided into a plurality of removable segments.

  In a sixth aspect based on the fifth aspect, it is preferable that a seal is provided between adjacent segments of the plurality of segments.

  Further, a seventh invention is the fourth invention, wherein the hatch cover is provided so as to be swingable or movable in a substantially horizontal direction when the hatch is opened and closed.

  According to an eighth aspect, in the seventh aspect, the hatch cover is configured to be lifted upward by a predetermined distance above the hatch.

  According to the first invention, the slide floor board can be slid in the front-rear direction with the tailgate on the rear surface of the luggage compartment closed. Thus, if a push plate similar to that described in FIG. 11 (description of the prior art) is installed, the load can be placed behind the cargo compartment using the slide floor plate and the push plate with the tailgate closed. Can be moved to. As a result, when bulk material is loaded into the cargo compartment, for example, even if bulk material is intensively introduced from the front of the cargo compartment, the slide floor plate and the push plate are moved and driven in a timely manner, and the bulk material is loaded into the cargo compartment. It can be loaded almost uniformly without any deviation.

  According to the second invention, if at least one of the sliding surfaces of the rear end portion of the sliding floor plate and the fixed floor plate is formed of a sliding member having a small friction coefficient such as hard resin and having good sliding properties, the sliding Even if the floor board and the fixed floor board are brought into close contact with each other and slid, failure such as seizure does not occur. As a result, since the sliding operation in the front-rear direction of the sliding floor plate can be performed smoothly, the load on the sliding floor plate can be easily conveyed onto the fixed floor plate, and the loading function in the first invention can be more reliably performed. It can be demonstrated.

  According to the third aspect of the invention, when a bulk material containing powder is loaded in the cargo compartment, even if the powder leaks from the gap between the movable parts of the slide floor plate, the bottom plate of the cargo compartment is sealed, so Scattering outside the cargo space can be prevented. Thereby, scattering of powder during traveling can be reliably prevented.

  According to the fourth invention, when a bulk material containing powder is loaded in the cargo compartment, for example, if the skirt of the cloth discharge duct of the loading hopper is fitted into the hatch and the bulk material is thrown in, the bulk material is It is possible to prevent the powder from being scattered during loading. Moreover, since the upper surface of the cargo compartment is covered with a roof, powder does not scatter during traveling of the transport vehicle. Furthermore, if a predetermined number of hatches are arranged side by side in the front-rear direction of the roof and are inserted from the respective hatches, the bulk material can be loaded into the cargo compartment substantially uniformly without any deviation. Furthermore, when used in combination with the first invention, even if the number of hatches is reduced (for example, when one hatch is provided in the foremost part), the bulk material can be loaded almost uniformly in the cargo compartment without any deviation. As a result, it is possible to easily prevent the dust from rising during loading and to prevent powder scattering during traveling.

  According to the fifth invention, since the roof can be easily attached and detached, the transport vehicle can be used as a general-purpose transport vehicle with the roof removed. Furthermore, since the roof can be divided into a plurality of segments, for example, if a roof is formed by combining a hatched segment and a non-hatch segment, the number and position of hatches are appropriately set according to the application. Therefore, the number of hatches depends on the bulk material with poor fluidity (ie with a large angle of repose) such as wood chips and the bulk material with granular and good fluidity (ie with a small angle of repose). Can be easily changed. As a result, the versatility of the transport vehicle can be greatly improved, and the implementation of the fourth invention becomes extremely easy.

  According to the sixth aspect of the invention, the powder in the load can be reliably prevented from scattering from the gaps between the segments constituting the roof, and the load can be prevented from getting wet in the rain. .

  According to the seventh invention, since a large space for opening and closing the hatch cover is not required above the hatch, in the loading yard where the ground height of the loading hopper is low and the distance between the loading hopper and the roof cannot be increased. In addition, the hatch lid can be easily opened and closed under the loading hopper. As a result of this, for example, as an example of work that may occur in the case of an upper opening hatch lid, stop temporarily before the loading yard, open the hatch lid, enter the loading yard, exit the loading yard, temporarily stop, and then hatch Since troublesome work such as closing the lid can be avoided, workability can be greatly improved.

  According to the eighth aspect of the invention, since the packing can be attached between the hatch and the hatch lid and the packing can be pressed in the vertical direction by the hatch lid, the airtightness of the hatch lid can be reliably ensured. Furthermore, since the hatch lid is lifted and rotated or moved in the horizontal direction, it is possible to install a cylindrical draining hem on the outer periphery of the hatch lid and cover the outer periphery of the hatch with this hem, Therefore, the intrusion of rainwater from the hatch can be reliably prevented. As a result, it is possible to easily prevent the load from getting wet when it rains.

  As a result of the above, it is easy to load almost uniformly into the luggage compartment, and even when bulk materials containing powder are loaded, dust rising during loading and powder scattering during traveling are prevented. In addition, it is possible to provide a transport vehicle having a deep body cargo room that can prevent the load from getting wet when it rains.
