Description

The invention relates to haymaking machines.

Known rake-tedders swathers containing a beam on the support wheels, the hitch, the mechanisms of rotation of the sections and the lifting mechanism of the sections with a hydraulic cylinder, bars with hinges and impellers. The hydraulic cylinder is connected with rods connected by two coupling nuts to the section turning mechanisms, the section turning mechanisms are pivotally connected to shock absorbers and section lifting pipes, the pipes are connected to the bars, and the bars are able to rotate 360 ° in the unlocked state together with the hinges and impellers, see RF patent No. 2301517, class. A01D 78/02.

These rakes have increased maneuverability due to tractor hydraulics and reduced specific material consumption.

The disadvantages of these rakes should include the insufficient width of the rake on each side of the bars, which reduces their productivity.

However, if the impellers are obviously added to the boards, this will lead to the need for the boards to be increased in length, which will negatively affect the mobility of the rake during transportation and increase their material consumption.

The objective of the invention is to create a rake with increased productivity due to the use of a larger number of impellers without increasing the specific material consumption of the rake and their dimensions.

The specified technical result is achieved by the fact that the rake-tedders swathers contain a beam on the support wheels, a hitch, section turning mechanisms and a section lifting mechanism with a hydraulic cylinder, the cylinder is connected to rods connected by two coupling nuts to the section turning mechanisms, the section turning mechanisms are pivotally connected to shock absorbers and section lifting pipes, the pipes are connected to the bars, and the bars are able to rotate in a vertical plane through 360 ° in a relaxed state together with hinges and working finger wheels arranged at their ends, while the beams of each section from one of the ends have two bending radii, each at an angle of 45 °, between the hinges located at the ends of each beam there is an additional hitch with two working finger wheels, with an additional hitch it is mounted with the possibility of removal on the beam by means of pin clamps and a pipe, a pine pipe lifting the section, all the linkages are L-shaped, and all the impellers of the section, starting from the extreme, lie in the follower ny parallel planes.

The invention is illustrated by drawings on which is shown in:

figure 1 - a rake in the position of raking and wrapping the roll;

figure 2 - a rake in the tedding position;

figure 3 - a rake in the transport position;

figure 4 - a rake in the transport position, a top view;

5 is a pin retainer bars;

6 is an impeller.

Tedder rakes have a beam 1 on the support wheels 2. A hitch is attached to the beam 3. A hydraulic cylinder 4 is mounted on the platform fixed to the beam, connected by four rods and two coupling nuts with section 5 turning mechanisms pivotally connected to shock absorbers. To the mechanisms for turning the sections, the lifting pipes of 6 sections are pivotally connected. The bars 7 with the help of pin clamps 8 are connected to the pipes for lifting the sections and have the ability in the unlocked state to rotate in a vertical plane 360 °. Two L-shaped hinges 9 are attached at the ends of the beams 7, at the ends of which two working pinwheels are installed in parallel planes 10. The angle of attack of the sections to the direction of movement of the rake is ensured by two adjustable coupling nuts 11 connecting the section lifting pipes to the rotation mechanisms sections.

Between the two hinges 9 of each section mounted hinge 12 L-shaped. The hinge 12 is mounted by means of a pipe 13, a pine lifting pipe of section 6. The pipe 13 is detachably connected to both the hinge and the beam 7 using pin clips similar to the clips 8. The location of the pipe 13 coaxially to the lifting pipe of 6 sections is necessary so that it is in the bars 7, additional bending moments of force did not occur. Since the two hinges located at the ends of the bars balance one another with respect to the arising moments, accordingly, the location of the hinge 12 coaxially with the lift pipe 6 will not cause any additional bending moments. This is very important so that all impellers are pressed evenly and with equal force to the ground.

The length of the pipe 13 is selected so that all the impellers of the section, starting from the extreme, lie in consecutive parallel planes. Since the tube 13 is detachably mounted on the beam, this makes it possible to quickly change failed parts, as well as adjust the position of the impellers relative to the beam.

To reduce the dimensions of the rake, which is very important when transporting them on roads, so as not to create difficulties for faster transport, the bars 7 from one end have two bending radii at an angle of 45 °. With this arrangement of the beams in combination with the L-shaped form of the hinges, there is practically no extension of the beams themselves, since the double bending forms a sufficient pocket for the location of the hinge 12. Moreover, the width of the section is such that it meets the conditions for its safe transportation when inoperative.

Use a rake for tedding, raking, wrapping and doubling the rolls.

Rakes work with tractors of class 0.6 ... 1.4.

Rake work on a tedding.

When the rake moves along the swath, the impellers 10 rotate due to adhesion to the soil or mass. Copying of the soil with the impellers is carried out by switching the tractor hydraulic system to the “floating” position, due to shock absorbers, swinging hinges and turning the bars at the junction with the section lifting pipes. Due to the location of the working finger wheels at an angle to the direction of movement and rotation, their sagging mass turns and moves approximately perpendicular to the plane of the wheels.

The tedding process is carried out in the case when each impeller, moving and fluffing up the mass, does not feed it into the zone of the next wheel (figure 2).

Reducing or increasing the pressure of the impellers on the soil is made by adjusting the force of the shock absorber springs with the help of coupling nuts.

The rake is moved to the raking position by turning the bars with hinges and impellers 180 ° in the vertical plane in the following sequence: release the clamps 8 with the lifting pipes of 6 sections, using the tractor hydraulic system lift the sections approximately 45 °, turn the bars 7 with the hinges 9 and 12 and the working finger wheels 10 to 180 °, combine the holes with the pipes for lifting the sections and insert the clips 8. Put the tractor hydraulic lever into the “floating” position, the sections are lowered and occupied horizontal position. The width of the rake grip and the width of the roll are adjusted with coupling nuts.

The raking process in the roll is carried out as follows: the dry mass captured by the first wheel is moved by the amount of capture of this wheel and fed into the coverage area of the second wheel, etc. Thus, after the passage between the rear impellers, a roll is formed.

The process of wrapping the roll is effected along it by any pair of rear impellers in the raking position, while the roll is shifted to the side and turns.

The rake is transferred to the transport position both from the tedding position and from the raking position and is carried out using the hydraulic cylinder 4 in the following sequence:

by switching the lever of the tractor hydraulic system, the rake sections rise, turning at an angle of 90 °, and are fixed between themselves by flexible stretching.

According to tests, the rake performance in comparison with the closest analogue increased:

when tedding 2.2 times;

when raking 1.7 times.

The specific fuel consumption of an energy tool when working with the claimed rake has not increased compared to the closest analogue.
