Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mat for removing mud clogged from the large wheels of heavy vehicles such as general passenger cars and trucks, and especially dump trucks, concrete mixer trucks, and the like.

The sludge and gravel that clog the wheels of large vehicles entering and exiting construction sites do not wash off easily even with water, but when the vehicle is in motion, it falls off due to the weight of the vehicle, resulting in dirt on the road. It was hot.

In order to easily remove the sludge from the wheels that is difficult to remove by driving the vehicle over it, this invention focuses on rigid filaments cut into appropriate lengths. A single brush material is clamped by clamping fittings, and the clamping fittings are bent into an annular shape so that the aggregation surfaces of the ends of the filaments form an annular shape. and a section is formed inside the boxes arranged in length, and has a depth of about half of the height protruding from the filament clamping bracket, and has a margin for the ring-shaped clamping bracket part of the single material. The ends of the filaments are placed in a number of small boxes having cylinders at the bottom large enough to fit into the ring-shaped clamping fittings made of a single material, with the ends of the filaments facing upward. It is characterized in that the cylinder is fitted into the annular clamping fitting so that it can be replaced.

According to the present invention having such a configuration, even if the deep grooves in the wheel treads are clogged with sludge or gravel, the rigid linear brushes can be removed simply by driving the vehicle over the mats and reciprocating them. The cylinder at the bottom of the small box is fitted into the ring-shaped clamping fitting of the single brush material, so the cylinder allows the single brush material to be pushed down by the pressure of the wheel. This not only prevents the brush from falling sideways in the box or causing the filaments to fall inward, but also prevents the brush from sticking to the wheels and being dragged out of the small box. Materials can be stored reliably and stably in each small box,
In addition, if the rigid filaments collapse due to the pressure of the wheels, the single brush material can be taken out of the small box and easily replaced, thereby immediately regenerating it as a pine with excellent brushing effects. be able to.

In the embodiment shown in the attached drawings, the mud removal mat is a shallow box 1 made of metal plate with partitions arranged in a grid pattern.
and a single brush material 2 that is fitted into each of the partitions of the box 1.

As can be seen in Figures 1 and 3, the box 1 is mainly made of a metal plate such as an iron plate, synthetic resin, or concrete.The box 1 is partitioned vertically and horizontally into a grid pattern, and is divided into a large number of small boxes 10, 10...
form... The height of the box wall 11 of the box 10 is about 1/2 of the height of a single brush material 2, which will be described later.

The single brush material 2 is made of a clamping metal fitting 21 having a U-shaped cross section, made of a rigid filament 20 made of vinyl resin, nylon, wire, etc., either alone or in combination.
The metal fitting 21 is bent into a ring shape large enough to fit into the small box 10, and formed into the shape shown in FIG. A strong material with a thickness of 1 mm is acceptable, but even if it is a synthetic resin filament or a wire, it will not be possible to rest on it if it is bundled as a single wire and clamped with the clamping fittings 21. There is a risk of deformation at any time due to the pressure of the wheels. Therefore, in order to make the single wire of the filament 20 even stronger, several to ten of the single wires 20 are braided into a rough string shape, and when this is used as a brush material, the strength and rigidity of the coarse string is improved. The brush material not only penetrates into the wheel grooves and scrapes off the sludge that is clogged in the grooves, but also has the toughness of the brush material so that even if it is knocked over by the pressure of the wheels, it immediately returns to its upright position once the pressure is removed. However, it has the advantage of maintaining its mud-removing effect.

When the single brush material 2 is fitted into the small box 10 of the box 1 with the fittings 21 facing downward, the brush portion of the single material 2 protrudes from the top surface of the box 1, as shown in FIGS. It forms a flat mud-shedding surface like this.

When the boxes 1 having the above structure are laid out in the required width and length to form a mat as shown in Fig. 1, and the inclined plates 3 and 4 for getting on and off the mat are laid before and after the mat, and the mat is used for removing mud. , the rigid filaments 20, 20... effectively wipe away the wheels of a vehicle passing slowly over the mat, and also penetrate sufficiently into the grooves of the wheel treads, thereby removing the sludge that clogs the grooves. Scrape off the gravel,
This made it possible to create a mat that was especially effective for removing mud from the wheels of heavy vehicles.

If the stiff filaments 20, 20 of the single brush material 2 break, fall down, or wear out due to the pressure of the wheels passing over the mat, the effectiveness of mud removal and wiping is reduced. If you take out the single material 2 from the small box and replace it with a new one, you will have a pine that continues to have excellent mud removal effects, and it has the advantage of being easy to replace.

In addition, the small box 10 is
There is a risk that the entire brush single material 2 fitted therein may fall sideways within the small box 10 or be attached to the wheels and be dragged out of the small box 10. Therefore, in order to prevent this, a single brush material 2 is placed in the center of each small box 10.
A cylinder 12 large enough to fit into the annular shape of the box is attached to the bottom of each small box 10, and drainage holes 13 and 14 are provided at the bottom of each small box 10, as well as to the partition wall 11 (not shown), if necessary. A general drainage hole shall be provided.

Claims (1)

[Claims] 1. Rigid filaments cut to appropriate lengths were gathered together and clamped between clamping metal fittings, and the clamping metal fittings were bent into an annular shape so that the collecting surfaces of the tips of the filaments formed an annular shape. A section is formed inside a box in which single brush material is laid out in a width and length that corresponds to the width and diameter of the wheel.
It has a depth of about half of the height protruding from the filament clamping metal fitting, and has a size that allows the ring-shaped clamping metal part of the single material to be fitted with a margin, and the ring shape of the single material It can be replaced by placing the filament in a number of small boxes with cylinders at the bottom that are large enough to fit into the clamping fixtures, with the ends of the filaments facing upward and the cylinders inserted into the annular clamping fixtures. A mat for removing mud from wheels of a vehicle, particularly a heavy vehicle, characterized by forming a mud removal surface for scraping off mud adhering to the wheels as the vehicle travels by being fitted into the mat.
