Description

[Detailed Description of the Invention] This invention relates to a tire desilting machine for large vehicles such as large trucks, which mainly have three axles (the two rear axles have double wheels).

In recent years, Japan's road paving rate has improved markedly, especially in urban areas, but there are still many unpaved roads in the outer areas, which means that the number of trucks traveling from the outer areas to the cities is increasing. The mud that adheres to the wheels of large vehicles, such as silt, is scattered and polluted on the city's paved roads, creating a serious problem that impairs urban beautification and public health. In addition, various large-scale construction works and civil engineering works are being carried out all over the place, especially in urban areas recently, and the construction sites have to be frequently visited and visited every day.
The number of large vehicles such as large trucks transporting concrete aggregate and various other materials is also large.
At construction sites, mud adhering to car wheels is carried out onto the city's paved roads and spread widely. In particular, in vehicles with a large load capacity, such as large trucks, which have three axles and two rear axle wheels that are double-wheeled, the vehicle may get stuck between the double-wheeled wheels. The amount of mud is large and stubbornly adhered to the city, and large amounts of mud are spread over long distances on the city's paved roads, which seriously undermines the beautification of the city and poses a threat to the city's environmental health. The current situation is such that a huge amount of money is wasted every year on road cleaning, etc., and there is a strong demand for a simple tire desilting machine for large vehicles.

This idea allows a car to ride on a mud-dropping drum in a predetermined position and simply rotate its wheels on the mud-dropping drum, automatically shaking off stubborn mud stuck to all wheels and tires in a single hour. This equipment provides tire desilting machines, and is installed at entrances and exits leading from various construction sites to paved roads, expressways, and city paved roads, etc., so that when we enter indoors, we can remove our shoes at matuto. By removing the mud thoroughly before entering a clean car, the conventional evils are completely corrected, contributing to the beautification of the city and public health, and the sense of superiority that comes from driving a car that is always clean. The purpose was to encourage self-respect and public morals.

The large automobile tire desilting machine of this invention will be described in detail below with reference to the drawings.

It is a mud-dropping drum shaped like a drum-shaped basket, which is connected by welding with a large number of iron rods 4 installed in a circle and gradually constricted from both ends toward the center with an appropriate taper. and each of the two rotating shafts 5, 5, rotating shafts 9, 9, and rotating shafts 10, 10.
The mud-dropping drums 2 are integrally attached to the left and right sides, respectively. In this case, the left and right wheels of the front axle of the truck 27 are placed on the front and rear mud-dropping drums 2, 2 on both the left and right sides of the front, and the left and right wheels of the rear axle on the front side are placed on the front and rear mud-dropping drums 2, 2 on both the left and right sides of the rear. However, the mud-dropping drums 2 are positioned so that the left and right wheels of the rear axle can ride on the front and rear mud-dropping drums 2, 2, respectively. And each rear rotation shaft 9, 10 of the two front and rear rotation shafts 9, 10.
A reversal prevention device 22, such as a one-way clutch, is provided at one end so that each can rotate only in one direction in the direction of the arrow in the figure. In addition, a control chain 15 is provided between the chain wheels 13a and 14 attached to the front rotation shaft 9 and the rear rotation shaft 10, respectively, and the intermediate shaft 28 and the front rotation shaft 9 supported between the center portions of the left and right step portions 7.
A control chain 17 is provided between the chain wheels 16b and 13b attached to the rear rotating shaft 5 and the intermediate shaft 28, and a regulating chain 20 is provided between the chain wheels 18a and 16a attached to the rear rotating shaft 5 and the intermediate shaft 28, respectively. A control chain 21 is connected between the chain wheels 19 and 18b respectively attached to the side rotation shaft 5, and the rotation shafts other than the rear rotation shafts 9 and 10, which can rotate only in one direction (back and forth rotation), are connected to each other. axis 5,
5 and both front rotation shafts 9, 10) are configured to be able to rotate in the same direction. That is, of the two sets of front and rear mud-dropping drums 2, 2 for rear left and right two-axle rear wheels, only the rear mud-dropping drums 2 are made rotatable in one direction, and each of the other mud-dropping drums 2 is wrapped around the transmission mechanism. They are connected so that they can rotate in the same direction. Reference numerals 23 denote side rolls that are attached to the mounting frames 24 at several appropriate positions on both the left and right sides of the base frame 1, so that the trucks 27 can move the front and rear mud-dropping drums 2, 2 so that each wheel can correctly straddle the wheel. Furthermore, 25, 25 is the base frame 1 mentioned above.
The right and left entry steps 26, 26 connected to the rear end are the right and left entry steps connected to the front end.

The automobile tire desilting machine of this invention has the above-mentioned configuration, and to explain how it is used, first, the truck 27 with mud adhered to each wheel is driven, and the machine is removed from the platform 25 on the left and right of the rear end. The left and right wheels of the front axle are placed on the front and rear mud-shedding drums 2, 2 on both the left and right sides of the front, and the left and right wheels of the front rear axle are placed on the front and rear mud-shedding drums 2, 2 on both the left and right sides of the rear. The left and right wheels of the side rear axle are connected to the same rear side front and rear mud removal drums 2,

These are designed to sandwich the central constriction of the front and rear mud-dropping drums 2, 2, respectively, so that they can be correctly mounted on both the left and right sides. When the truck 27 is driven and the front rear axle is driven to rotate, the rotation of the left and right wheels (double wheels) causes the front and rear mud-shedding drums 2, 2 on the left and right sides of the rear front side on which they are straddled, to induce friction. rotated, and at the same time each other mud removal drum 2
is rotated via a transmission mechanism, and the track 27
All remaining wheels are caused to rotate by friction induction. Therefore, while the tires of all the wheels of the truck 27 rotate at high speed, the mud adhering to them can be shaken off and wiped off by the rotation of the front and rear mud removal drums 2, 2 on which they ride. be.

In the above embodiment, the base frame 1 is fixed on the ground, and the entry step 26 and the entry step 25 are installed at the front and rear of the base frame 1, respectively. It is also possible to install the base frame 1 inside the vehicle so that the truck 27 can be entered and exited from the ground without the entrance step 25 and the exit step 26, and the base frame 1 can also be installed in the front mud-dropping drum attachment section. It may be divided into three parts: a left and right step part, and a rear mud-dropping drum mounting part.

As mentioned above, the tire desilting machine of this invention has a simple structure, and all that is required is to install it at an appropriate location on the entry point of a paved road, and then the driver drives the truck 27 to enter the vehicle, and each wheel is moved to the front and rear of the road, respectively. If you ride the mud drums 2 and 2 and rotate the wheels at high speed,
This is a dry method that automatically and extremely efficiently removes and wipes off mud adhering to each wheel by rotating the front and rear mud-dropping drums 2, 2, and also uses self-propelled rotation after a truck is driven into the vehicle and set in place. Therefore, it is extremely economical and does not require any manpower or expense, and by installing it at entrances to paved roads, expressways, etc., it can greatly contribute to urban beautification campaigns, public health, and traffic safety. It has outstanding effects such as

The front and rear mud-shedding drums 2, on which the tires of each wheel ride, are constructed by connecting several disks 3a arranged parallel to each other at appropriate intervals with a large number of iron rods 4 extending around their peripheries. It has a drum-shaped structure that gradually constricts from both ends toward the center with appropriate tapers, so when carrying out rotating mud removal with the wheel tire placed in the center, it gradually becomes thicker from the center toward both ends. Due to the tapered shape, the wheel tires (especially the double-wheeled rear wheel tires) are always located in the center of the front and rear mud-shedding drums 2 and are prevented from sliding to the left end or right end. is,
The excellent effect of being able to efficiently and completely scrape off and wipe off the mud adhering to each iron bar 4 in a stable state at all times, especially the stubborn mud stuck between the wheel tires. There is.

Furthermore, since only the rear mud-shedding drums 2 of the two sets of front and rear mud-shedding drums 2, 2 for the two rear left and right rear wheels are rotatable in only one direction in the direction of the arrow, the above-mentioned tire After completing mud removal, the truck 27 can be easily moved forward from the machine by backing up the truck 27 slightly, placing the front left and right rear wheels on the intermediate platform 11, and then starting forward. be.
