RU55342U1 - TRANSPORT MACHINE - Google Patents

Abstract

The utility model relates to the construction of transport vehicles and can be used in agriculture. The technical task is to reduce the specific pressure on the soil in order to reduce its compaction, as well as reduce the wear of the tracks. The technical task is achieved by installing on-board gear sleeves instead of the usual serial wheels of caterpillar tracks with a triangular track circumference, and instead of serial front wheels, wheels with wide-profile arched tires are installed.

Description

The utility model relates to the construction of transport vehicles and can be used in agriculture.

The famous Kirovets tractor K-700, containing a frame, engine, transmission, wheels and a control cabin (B.F. Kosenko. Tractors. Lenizdat. 1968. p. 255) is a prototype.

The disadvantage of the chassis of the K-700 tractor is a deep, up to 65 cm, soil compaction when working on arable land, as a result of which the yield of crops sharply decreases along the track of the tractor.

The technical task of the utility model is to reduce the specific pressure on the soil in order to reduce its compaction, as well as reduce track wear.

The technical task is achieved by installing on-board gear sleeves instead of the usual serial wheels of caterpillar tracks with a triangular track circumference, and instead of serial front wheels, wheels with wide-profile arched tires are installed. This increases the footprint and reduces the specific pressure on the soil.

The installation of a device to increase the span of the sprocket of the track allows you to reduce the tension of the track and therefore reduce its wear. This is also facilitated by the installation of a device over the caterpillar to clean it of dirt.

Comparison of the proposed solution with the prototype shows that it differs in the following features:

1. Instead of rear wheels, the tractor has tracked engines with a triangular track circumference;

2. Instead of front wheels to increase the supporting area are installed

wide-profile arch tires;

3. To reduce track wear, a device is installed on top to clean the track from dirt.

4. To increase the span of the sprocket by the caterpillar, a device is placed above it to increase the span of the sprocket of the sprocket.

Therefore, the claimed solution meets the criterion of "novelty."

The utility model can be manufactured on standard equipment using well-known processes, therefore, it meets the criterion of "industrial applicability".

Figure 1 shows a transport machine. The machine has wide-profile arch tires 1, a caterpillar mover with a triangular contour of the caterpillar 2, a device for cleaning dirt 3, a device to increase the angle of the sprocket of the sprocket track 4, the drive sprocket 5.

The machine operates as follows.

Torque is transmitted from the transmission to the drive sprocket 5, which drives the caterpillar mover 2, and also the torque is transmitted to the front drive wheels 6.

For more efficient operation of the caterpillar mover 2, a device is provided for cleaning the caterpillar from dirt 3 and a device for increasing the angle of coverage of the sprocket with the caterpillar 4.

When such a machine is working on arable land, the tractor's supporting area on the soil increases, which leads to a decrease in soil compaction to 10-15 cm.

Claims (1)

A transport machine comprising a frame, an engine, a transmission and a control cabin, characterized in that caterpillar track drives with a triangular contour of the caterpillar equipped with a device for cleaning the track from dirt are installed at the rear of the machine, and wheels with wide-profile arched tires are installed in the front part.
