Description

The proposed technical solution relates to transport and technological machines, which can be used, including in agriculture, as a tractor or agricultural chassis to perform various agricultural and transport operations on various soils, especially with low bearing capacity.

The possibilities of using agricultural machines to perform various transport and technological agricultural work, especially on loose soils with low bearing capacity, are limited. This is due to the large (over 1.0 kgf / cm ² ) pressure on the soil created by the wheels of the agricultural machine, which leads to the destruction of the soil structure, reduced maneuverability of the machine and the formation of a track under its wheels, which is highly undesirable, especially when driving on crops.

Known transport and technological agricultural machinery (TTC), for example, the tractor LT3-155, containing an engine and four-wheel drive four-wheel chassis on pneumatic tires (magazine "Special vehicles 2000", Third Rome, 2000, p 57).

A well-known universal transport-operational agricultural machine (see RF patent for PM No. 21177 dated July 10, 2001 for MPK V62D 63/00 is a prototype), containing an engine, a chassis in the form of a frame with two driving axles on pneumatic tires with ultra-low internal pressure in t .h. 5-60 kPa, transmission (these signs are common with the stated solution). In addition, it is equipped with a device for mounting mounted, semi-mounted and trailed agricultural equipment.

A disadvantage of the known technical solutions is the significant turning radius of the TTC and, consequently, the insufficiently wide functionality of the device, which does not allow full use of the high throughput of a transport-technological machine of this type in narrowed areas or other places where a large turning radius is not desirable.

The purpose of the proposed technical solution is to eliminate these drawbacks, namely the expansion of the functionality of the transport and technological machine, including and by acquiring the possibility of turning the TTS with a reduced radius.

This goal is achieved by the fact that in the well-known transport-technological agricultural machine containing a frame mounted on three bridges operating on ultra-low tires, including from 5 to 60 kPa of internal pressure, at least two of which are driven, the internal combustion engine and transmission, according to a utility model, the front axle is made with steered wheels, and the distances between the axles of the axles are related by the ratio where L1 is the center distance between the front and middle axles, L2 is the center distance between the rear and middle axles, in addition, it is equipped with a power take-off shaft for driving attachments, including mounted on the frame.

The second option to achieve this goal is a transport-technological agricultural machine containing a frame mounted on three bridges operating on ultra-low tires, including from 5 to 60 kPa of internal pressure, at least two of which are made by the leading ones, an internal combustion engine and a transmission in which, according to the invention, the front and rear axles are made with steered wheels, and the distances between the axles of the axles are related by the ratio where L1 is the center distance between the front and middle axles, L2 is the center distance between the rear and middle axles, in addition, it is equipped with a power take-off shaft for driving attachments, including mounted on the frame.

In the third version, the machine differs from the first two only in that the mounted equipment mounted on the frame is made in the form of a granular fertilizer spreader.

In the fourth, attachments are made in the form of a sprayer mounted on the frame for chemical treatment of fields.

In the fifth, attachments are mounted on the frame and made in the form of a kung (for a team of repairmen) equipped with an electric generator.

The specified set of features exhibits new properties, namely, due to their use, the device has a new quality, expressed in increasing its functionality in combination with high passability and a small turning radius. Therefore, the proposed utility model meets the criterion of "Novelty."

The presence of the criterion of "industrial applicability" is confirmed by the proposed example of a specific implementation of this technical solution, a diagram of which is shown in Fig.1-5, which gives a schematic diagram of the device (options) in which

The transport and technological machine (Fig. 1) contains a frame mounted on ultra-low pressure tires 1 with an operating pressure of about 10 kPa, an engine 2, including a housing with a crankshaft, one end of which is docked through a gearbox 3 with a drive axle 4, and the second end has a sealed outlet from the housing and is docked to the power take-off shaft 5 for the functioning of attachments (6, 7, or 9,) mounted on the frame. The ratio L ₂ \ L ₁ = 0.6 since this is the optimal value for a TTC with three bridges, the extreme of which are leading, and the front ones, in addition, are controllable.

Figure 2 shows the TTC, which differs from the first in that both the front and rear axles in this case are controllable, with the ratio L ₂ \ L ₁ = 1, (since this is the optimal value for this option). The optimality was determined from the conditions of the minimum turning radius and minimum energy consumption during the rotation (turn) of the triaxial TTS on wide-profile ultra-low pressure tires (5-60 kPa).

Figure 3 presents a variant of the TTC with attachments mounted on the TTS frame, made in the form of a granular fertilizer spreader 6, the drive of which is carried out from the power take-off shaft 5.

Figure 4 presents a variant of the TTC with attachments mounted on the TTC frame made in the form of a sprayer 9 for chemical treatment of fields, the drive of which is carried out from the power take-off shaft 5.

Figure 5 presents a variant of the TTC with attachments mounted on the frame of the TTC, made in the form of a kung 10, equipped with an electric generator 11, the drive of which is carried out from the power take-off shaft 5.

The operation of the device is as follows. When starting engine 2, the crankshaft starts to rotate, and with it the power take-off shaft 5, which drives the attachments, including and mounted on the frame of the TTC (spreader 6 or sprayer 7 or generator 9). Due to the fact that the relation L ₂ \ L ₁ satisfies the condition , TTS in this case has a significantly smaller turning radius with minimal energy consumption for it, which with the presence of equipment located on the frame, significantly increases the functionality of the triaxial TTS on wide-profile tires of ultra-low (5-60 kPA) internal pressure.

Thus, the use of the proposed technical solution will reduce the TTS turning radius with reduced energy costs for this maneuver, and thereby increase its functionality.
