Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of a conveyor device capable of moving cargo by a conveyor body supported by a pair of left and right chains.

(b) Conventional technology Conventional conveyor devices span a chain between a pair of front and rear sprockets, a conveyor body is attached to the chain, and the chain is driven.
It is designed to move the cargo on the conveyor body.

However, when the above structure is installed on a freight vehicle, for example, the waste on the conveyor device may scatter onto the road, or the waste on the road may fly up and adhere to the conveyor device. It was necessary to install a floor plate below the equipment.

(c) Problems to be solved by the invention However, in the case of a structure in which a floor plate is provided below the conveyor device, although the above-mentioned drawbacks can be solved,
It has been very difficult to clean the waste accumulated on the floorboards because the conveyor device and the floorboards are close to each other.

(d) Means for Solving the Problems The present invention solves the above-mentioned drawbacks by providing a pair of front and rear sprockets, and between the pair of sprockets, a chain driven by an appropriate drive means is connected to the left and right. A conveyor body is provided between the pair of chains, a floor plate for preventing waste from scattering is provided below the entire conveyor body, and a part of the conveyor body or between the pair of chains extends in the left-right direction. This invention relates to a floor cleaning device for a conveyor device, in which a cleaning brush is attached so as to be in sliding contact with the floor surface, and the floor plate is further provided with an outlet for discharging waste collected by the brush and for replacing the brush. be.

(e) Embodiment The following embodiment will be explained with reference to the drawings. Fig. 1 is an overall view of the present invention installed in a freight vehicle, and numeral 1 indicates a van-shaped cargo box mounted on a vehicle body 2. A door 3 is provided at the rear of the cargo box 1, and a conveyor device 5 for moving cargo is provided on the floor plate 4 of the cargo box 1.

The conveyor device 5 will be explained below.6,
Reference numeral 6 denotes sprockets provided at the front and rear, and a pair of left and right endless chains 7, 7 are spanned between the pair of sprockets 6, 6, and between the left and right chains 7, there is an end on which a load can be placed. A conveyor body 8 having a shape is provided.

The conveyor main body 8 is provided with metal slats 9 and shielding members 10 made of vinyl chloride alternately, so that it is possible to transfer the powder and granules and also to move in an arc.

A protective frame 11 is provided at the front end of the conveyor body 8 to prevent cargo from collapsing.
consists of an underframe 12 having a predetermined width and a stand 13 erected on the underframe 12, and by fixing both ends of the underframe 12 to the chains 7, it moves with the movement of the conveyor main body 8. It's becoming like that.

The rear end of the conveyor body 8 is turned downward, and a cleaning brush 15 having approximately the same length as the slat 9 is fixed to the slat 9 at the rear end via a bracket 14. The brush 15 cleans the floor surface 16 of the packing box 1, and the collected garbage and the like are formed on the rear part of the floor plate 4.
It is designed to be able to discharge downward from a discharge port 17 which is approximately the same length as the discharge port 17, and the discharge port 17 is normally closed with a lid 18.

Further, when the brush 15 becomes worn, it can be replaced through the discharge port 17.

A frame 19 is provided between the upper and lower chains 7, 7 passing through in the left-right direction, and both ends of the frame 19 are provided with protective covers 20, 2 forming part of the side wall of the cargo box 1.
Fixed to 0.

Rails 21 are fixed on the pedestal 19 in the front-rear direction at appropriate intervals.

Support members 22 for directly supporting the conveyor body 8 are provided within the rails 21.

The supporting members 22, 22 are made of a polymer compound with a small coefficient of friction, such as plastic, in order to reduce the moving load of the conveyor body 8.

23 is a screw for holding the lid 18 closed. A cover 24 protects the conveyor body 8 from forks of a forklift.

Reference numerals 25, 25 are girders fixed to the frames 19, and are designed to support the chains 7, 7 that have been moved upward.

In the embodiment, the case where the conveyor device is used in a freight vehicle has been described, but the same effect can be obtained even if the conveyor device is used alone.

Furthermore, although the brushes are attached to the conveyor body in the embodiment, they may also be attached to a pair of left and right chains.

Furthermore, it is also possible to make the conveyor body endless.

The present invention has the above-mentioned structure. Next, the operation will be explained. First, when unloading the cargo on the conveyor main body, the chains 7, 7 are moved clockwise by appropriate driving means from the state shown in FIG. 3. .

Since the protective frame 11 also moves rearward accordingly, the cargo can be unloaded sequentially from the rear of the cargo box 1. When loading cargo, the protection frame 11 moves the chains 7, 7 counterclockwise from the rearmost position. Since the protection frame 11 moves forward accordingly, the conveyor main body 8 also moves forward, and the cargo can be loaded onto the conveyor main body 8 one after another.

By the time the cargo transport work is completed, waste has accumulated on the floor 16 of the cargo box 1, so first remove the screws 23 at the rear of the floorboard 4, then rotate the lid 18 downward to open the discharge port 17. I'll keep it.

In this state, the protection frame 11 is moved forward, the brush 15 provided on the conveyor body 8 is moved backward, and the waste on the floor surface 16 is discharged from the discharge port 18.
When the discharge is completed, the discharge port 17 is closed.

(f) Effects of the Invention As described above, the present invention provides a brush on the conveyor main body or chain and also provides a discharge port on a part of the floor plate, so that the brush is brought into sliding contact with the floor surface when the chain is driven, and the brush is removed from the floor surface. The garbage on the floor can be cleaned, collected and discharged, and the floor surface can be cleaned easily and reliably.

Furthermore, since the brush faces the outlet side, it can be replaced more easily than the outlet.
