Description

The invention relates to agricultural harvesting machines, and more specifically to rotary mowers designed for the mowing of sunflower and natural grasses.

The purpose of the invention is to simplify the design and maintenance, as well as reduce the metal intensity.

FIG. 1 shows a rotary mower, top view; in fig. 2 - the same, rear view; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a sectional view BB in FIG. one; in fig. 6 is a section of YY in FIG. one; in fig. 7 - section DD in FIG. one; in fig. 8 - principle hydraulic diagram of the rotary mower; in fig. 9 is a section of the EE of FIG. five.

The proposed mower contains rotor bar 1 (Fig. 1 and 2) with rotors 2 mounted on it, console 3, swivel frame 4, fixed frame 5, pull fuse 6, lifting mechanism 7, front guard 8 rotors, rear guard 9 rotors, removable bracket 10 with vertical uprights 11, piles 12, the lower axis 13 of the movable frame, the upper axis

hoses 27 and oil lines 28 to flow dividers 25. Next, the flow of the working fluid, divided into four equal flows, through the discharge sleeves 19 (Fig. 2) enters the oil lines 36 (Fig. 4), each of which supplies the working fluid to one of the hydraulic motors 31, driving them into rotational motion. The motors are mounted on brackets 32, on which a shaft is mounted on ball bearings and is connected to a hydraulic motor and a rotor with knives.

Thus, the rotors 2 cut the mass to be removed with knives, and when the machine moves forward, the mass removed is thrown back by the rotors 2 backward, heaps 12 (Fig. 1) form a roll of the required width behind the rotor bar.

Next, the flow of working fluid through the drain oil line 35 (Fig. 4) enters the drain hose 17 (Fig. 2) and is fed to the console 3, which is both a drain line and a radiator for cooling the working fluid.

Then the cooled working fluid through the drain sleeve 18 enters through fil20

14 of the movable frame, the bracket 15 is fastened 25 to the oil pipe, the element 20 in the oil reservoir.

The device works in the following way.

The mower is hinged on the mounted device of the tractor with lower longitudinal t-rods on axles 16 (Fig. 3), upper central thrust on the bracket 15.

When turning on the tractor's power take-off shaft, the coupled hydraulic pump 23 (Fig. 1) sucks the oil through the suction hoses 26 out of the tank and delivers it to the blower0

hoses 27 and oil lines 28 to flow dividers 25. Next, the flow of the working fluid, divided into four equal flows, through the discharge sleeves 19 (Fig. 2) enters the oil lines 36 (Fig. 4), each of which supplies the working fluid to one of the hydraulic motors 31, driving them into rotational motion. The motors are mounted on brackets 32, on which a shaft is mounted on ball bearings and is connected to a hydraulic motor and a rotor with knives.

Thus, the rotors 2 cut the mass to be removed with knives, and when the machine moves forward, the mass removed is thrown back by the rotors 2, the blades 12 (Fig. 1) form a roll of the required width behind the rotor bar.

Next, the flow of working fluid through the drain oil line 35 (Fig. 4) enters the drain hose 17 (Fig. 2) and is fed to the console 3, which is both a drain line and a radiator for cooling the working fluid.

Then the cooled working fluid through the drain sleeve 18 enters through fil0

5 trundle, element 20 to the oil reservoir.

To eliminate the occurrence of pressure in the oil tank when the working fluid is drained, a breather 21 is provided in its design. With possible overloads occurring on the rotors, the system is discharged through safety valves 24 (Fig. 1) mounted on the swing frame-tank.

When the tractor and hydraulic pumps 23 (Fig. 1) are stopped, the hydraulic motors 31 (Fig. 4) start to operate in pump mode, sucking the working fluid through the check valves 30 (Fig. 6).

When a beam 1 hits a possible obstacle, the tapered Bajr 45 (Fig. 3) overcomes the force of the springs 46 and disengages from the taper hub of the swing frame 4, the rotor timber with the swing frame and the hinged console 13 and 14 (Fig. 2

and 3) leans back, eliminating the canopy. The tractor rotor retracted to its original position.

The lifting of the rotor beam 1 at turns at the end of the ramp and into the transport position is carried out by the hydraulic cylinder 37 (Fig. 3),

which is connected by an extension 38 of the hydraulic cylinder rod through a connecting nut 39 with a slider 41, which in turn through the brackets 42, the bracket 43 and the coupling 44 is connected to the bracket of the console 3.

The pressure of the rotor beam 1 (Fig. 1) on the ground is regulated by four springs 40 (Fig. 3), which are fixed at one end to a stationary hydraulic cylinder

pa 37, and the second through tension bolts — with a slider 41.
