The invention relates to agricultural machinery, in particular to assemblies with a pull rope for agricultural and reclamation works, and can be used for cleaning in the rice fields, especially at high soil moisture.

Known unit with a pull rope, mainly for the cultivation of vineyards on the slopes, including a motor truck with a winch connected by rope to a fixed anchor, and a cutting knife pivoted on an axis with the possibility of change is Gata is the inability to use it for harvesting rice self-propelled combine harvester in the rice fields with high soil moisture.

Also known self-propelled rice-picking harvester containing the motor to move the machine and turn it on (Izakson H. I. Grain combines "Niva" and "ear", M. Kolos, 1980).

However, with a strong soil moisture in paddy fields self-propelled rice combine harvester even on tracks (ACS-6 "spike") slips, making it impossible to harvest rice.

Closest to the invention to the technical essence and the achieved effect is a unit with a pull rope for agricultural and reclamation works, including the technological cart with working bodies and supporting wheels located on opposite sides of the truck power tools with winches, cable-and-pulley system of winches related to the technological cart, and drive.

The disadvantage of this unit is the presence of complex assemblies for the spread of technological truck at the end of the rut and when translating from one rut to another, which does not ensure reliable operation of the plant when harvesting rice in wetland checks and, in addition, it is not possible to use the same technology cart (instead of which in the inventive Assembly can be used self-propelled RISO the traveler or planting rice in the fields. Therefore, the known Assembly is used for simple operations, such as cultivation, which do not require such care as if the machine moves or direct combine harvesting or cleaning roll in check.

The aim of the invention is to improve the efficiency, economy and reliability of operation in conditions of extremely moist soil in paddy fields by simplifying the design and reducing capital and labor costs for its production and maintenance.

This is achieved by the fact that in the known unit with a pull rope, including technological cart with the engine, for example, self-propelled rice combine harvester, power tools with winches located on opposite sides of the truck, a cable-and-pulley system of winches associated with technological trolley, industrial trolley is equipped with an adjustable mast with two pulleys on the end through which it is connected with cable-and-pulley systems, winches and with a drive pulley truck, the mast can rotate around its own axis and around the axis of the drive pulley of the truck in a vertical plane coincident with the longitudinal axis of the technological cart.

In Fig. 1 shows the unit with kanatal, acting on the fixed ends of the wire rope on the winch power tools, and external technological boom truck.

Unit with a pull rope for agricultural and reclamation work includes (Fig. 1-4) technological cart, for example self-propelled rice-picking harvester 1, two power tools 2 winches 3 located on opposite sides relative to the technological trolleys, cable-and-pulley system 4 winches 3, removable swivel mast 5 with two pulleys 6 at one end and a driven pulley (not shown), bogies, traction ropes 7 connecting cable-and-pulley system of winches with the technological cart through pulleys 6 swivel mast.

The mast 5 is installed on the rotary base truck, able to rotate around the vertical axis, the mast can rotate around the axis of the drive pulley of the truck in a vertical plane coincident with the longitudinal axis of the technological trucks, in the direction of the forces acting contacts 7 on the pulleys 6.

Drive pulley (not shown) of the truck is able to move the cart by choosing the rope 7 in one direction or another at full slip self-propelled chassis of the truck 1 and the failure of perematyvanie rope 8 with minimum expenditure of energy. When moving the self-propelled truck with power tools drive pulley is locked.

The unit works as follows.

At the beginning of the operation of the unit during the harvest in paddy fields with very high soil moisture establish energy means 2 (Fig.1-4) with winches 3 and cable-and-pulley systems 4 at opposite sides of the check in front of the technological cart (self-propelled harvester) and fill the traction rope to the mast 5 with two pulleys on the end and the drive sheave trolley, adjust the position of the mast with the pulleys on the end of a rotation around its axis vertical so that the pulley on the end of the mast was vertical axis coinciding with the longitudinal axis of the truck. This mast can be tilted in a vertical plane backward relative to the direction of movement of the truck to prevent tipping of the truck when towing checks in with very wet soil. When moving technological cart includes 3 power winch means 2 located in front of the truck (Fig. 1), and with a traction rope 7 associated with the mast 5, the cart is towed to the end of the rut, with winch 3 opposite the power trolley.

At the end of the rut, to which came the combine, move both power tools 2 winches 3 on the next pass, simultaneously turning on the machine in the desired position using the actuator to the mast 5, which being connected with hauling rope 7 with cable-and-pulley system 4 winches 3, provides a reversal of the harvester without ocalenia from the power means with the winch when it is spread.

After turning the truck and setting it on the following gona include winch 3 opposite the power generating device 2 for winding the traction rope 7 than provide towing torque truck in very wet soil, with winch, remaining at the rear of the truck, unwind rope 7, which stretches for moving the cart to the end of the rut, etc.

When using the unit with a pull rope for agricultural work running the truck engine is used at full capacity only on the turns at the end of the rut, and on the straights when very wet soil of rice paddies for movement of the trolley 2 are primarily used traction winches through the traction ropes 7 or the drive pulley trolley, which prevents the destruction of the surface layer of the soil ravegnini soil.

Despite the fact that during movement of the trolley along the mating line of thrust due to the tension of the ropes 8 winch directed at an angle to the horizon (Fig.2 and 4), the vertical component of the tension of the ropes, promote the penetration of the wheels of the truck in the soil corresponds to the additional weight of the truck, for example, equal to 260 kg, compared to its main mass is 2%

For towing rice-picking harvester weight 12000 kg in highly alaninol soil of rice paddies take the most unfavorable conditions for rolling with the movement of the harvester,characterized by the coefficient of resistance to rolling, equal to fm=0,44 Necessary traction for towing harvester (Samohodnoy combine and towing free unwinding of the rope from the second power means is not taken into account) is equal to

P=fmg=12000 0,44 9,81=52000 H. (1)

Taken with a large stock of steel wire rope h=222 22 mm diameter with a breaking load from 200500 to 272500 N with a weight per meter of rope, q= 1.638 kg/m

The basis of the arguments based on the calculated dependences for sagging flexible strands.

According to the above scheme the difference between the levels of attachment of the rope to an arrow of the harvester and to the winch equal to h=2 m, DLC (X, Y) is equal to

fx= (2)

Maximum SAG when X is equal to

f 3,55 m

(3)

If we take the height of the attachment point of the rope to the boom Assembly is equal to H=6 m, you can see that in terms of towing pull rope will not touch the soil, so as H>fmax.

From the drawing follows the equation of a curve deflecting flexible strands

y=xtg +fmax, (4) and the angle of the tangent to the curve SAG is determined by the derivative

tg tg

(5) if x tg tg

Angleinat point b (X=l)

tgB= tg+ + 0,05 rad

(6)

The vertical component of the tension contributing to the indentation process truck into the soil, will be determined by the expression

Rb=Ptgin=52000 0,05=2600 H, (7) which corresponds to the additional weight of the harvester 260 kg, compared to the bulk of the harvester 12000 kg is slightly more than 2%

Determine the horizontal component of the tension (expansion) of rope from his weight taking into account (3)

Pto= = 51800 H

(8) Shows that R>Rto. In equation (7) in the calculation adopted a great value. Obviously, when Rto>P rope could reach the ground.

It is also obvious that a machine will also have a tipping point is an arrow, it is advisable to rotate in the opposite direction relative to the direction of movement of the harvester.

However, for self-propelled combine or planter traction will be much less compared to the adopted in the calculations and the overturning moment, as additional pressure on the soil, will be much less.

The use of a rotary mast with external boom, communicating through the tension of the rope, the self-propelled harvester (technological cart) with cable-and-pulley system of winches, allowed us to simplify the design of the unit due to the refusal of a complex system of hard-leverage automation in the prototype to turn the harvester moving energy funds with winches on the next pass without disconnecting them from the combine.

In addition, the proposed design of the unit allows to increase the reliability of its performance in terms of harvesting rice in wetland checks, and reduce capital and operating costs in its manufacture and maintenance compared to the prototype.

UNIT WITH a PULL ROPE FOR AGRICULTURAL AND RECLAMATION activities, namely harvest in paddy fields, including technology cart motor, power tool with winches located on opposite sides of the truck, a cable-and-pulley Zavorotny around its own axis mast with two pulleys on the end and a driven pulley, associated with cable-and-pulley systems, winches, mast installed with the possibility of rotation around the axis of the drive pulley in a vertical plane coincident with the longitudinal axis of the technological cart.
