Abstract

PURPOSE:To make the titled equipment compact by installing two rollers which support both left and right tires of one shaft in a dropped position as well as one roller which supports both left and right tires of another shaft at the bottom and by allowing all tires to be supported in a stabilized manner. CONSTITUTION:Front and rear rollers 1 and 2 which support both left and right tires (a) in a dropped position, and a roller 3, which supports both left and right tires (b) approximately overhead and a passage bridge 4 are installed on a frame 5 provided with a cleaning water injection unit 6. The rollers 1, 2, and 3 comprise steel pipe 15, a slip prevention member 16, a disk 17 and a pivot shaft 18. This construction makes it possible to support all tires (a) and (b) in a sufficiently stabilized manner to make the work of cleaning off the mud even when three rollers 1, 2, and 3 are used, thereby allowing the entire equipment to be brought into compact size and low weight.

Description

[Detailed Description of the Invention] A bottle for removing mud adhering to the tires of large vehicles such as trucks, dump trucks, and trailers for the purpose of preventing road pollution just before they leave civil engineering or construction sites and exit onto general roads. Conventionally known tire desilting machines used for this purpose generally have four tire support rollers in the front and rear, in order to simultaneously desilt all left and right tire groups of the two rear axles of the large vehicle. Equipped with book rollers.

In other words, the two front rollers support the left and right tires on one shaft in a dropped shape S, and similarly the two rear rollers support the left and right tires on the other shaft in a dropped shape! This is to support IK. This four-roller type has the advantage of being able to stably support all the tires, but when a vehicle gets in and gets out after de-sludge, the tires ride on the rolls and slip. Not only does the rear part of the vehicle suffer from splashing (PTM), which causes discomfort to the vehicle driver, but the frame that supports the roller group has a large front-to-back length, which is a factor that increases the size and weight of the vehicle, which in turn increases costs. Ta.

In view of this point, the present IjlIFi aims to solve the above-mentioned inconvenience without causing abnormal flashing in the tire posture during mud removal.

The tire desilting machine Fi according to the present invention includes a group of rollers that should be equipped with it: two front and rear rollers that support the single-axis left and right tires in a dropped state, and one roller that supports the other l-axis left and right tires at or near the bottom thereof. 1 total 3 with 2 rollers
It is important to install a roller to maintain parallelism between the tire axis and the roller axis, and to prevent the tire from moving forward or backward during desilting.

This can be achieved sufficiently by supporting the left and right tires on the left and right axle, so it is possible to achieve this by dropping the left and right tires on the other axle. Since the front and rear positions of one roller are fixed, there is no need for slippage to occur due to slippage that would occur if the roller is supported biased to either the front or back (even if it occurs, it is only a small amount), so three Even rollers support all the tires in a sufficiently stable manner, so the front and rear lengths of these support frames can be significantly shortened compared to conventional ones, and the lower detached mud (water) storage tank is created by shortening the frame. The dimensions of the sludge removal device for the sideways parts can also be reduced, making the overall design considerably more compact and lightweight.
As a result, it is possible to achieve considerable cost reductions in terms of component parts and their assembly work.
In addition, since there are three rollers, the rear splash V when the vehicle enters and exits can be reduced more than before.

An embodiment of the present invention will be described below based on the drawings.
