Description

(54) SOIL-REVERSING MACHINE

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to tillage machines.

Known tillage machines with tilting rotors for tillage are known, in which torque is transmitted to drive the rotor shaft through a side drive made in the form of a multi-stage helical gearbox or in the form of a chain gear 1J.

Closest to the proposed technical entity is a soil processing machine that includes a drive machine mounted on a horizontal shaft with an output shaft and a transmission mechanism 2.

The disadvantage of this machine is the low reliability of the transmission mechanism due to the high content of gearing wheels that are prone to rapid breakage.

The purpose of the invention is to increase the reliability of the machine.

The delivered chain is achieved by the fact that the transmission mechanism is made in the form of rigidly mounted on each of the shafts installed with the same eccentricities and angular displacement of at least two eccentrics, the opposing of which are pairwise interconnected

10 connecting rods with bushings covering eccentrics, the magnitude of the angular displacement is a multiple of It / n, glad, where n is the number of eccentrics mounted on the shaft.

Claims (2)

The tillage machine consists of a frame 1, a drum 2, a gearbox -3, a gear 4 at the output shaft 5 and support wheels .6. Frame 1 contains a hinged device 7, sidewalls 8, peyopny 9 and rear 10 aprons. Freibaraban consists of a horizontal shaft 11 and knives 12. The shaft 11 is mounted on under the pinions fixed on the sidewalls 8, the gear mechanism 3 is made in the form of a shaft 5 and P mounted on each of the two installed with the same eccentricity and angular displacement of six eccentricles 13 matched in pairs between each other with connecting rods 14 with eccentric sleeves with sleeves 1 5. The number of eccentrics can be from two to six pairs. With three pairs, their coarse bias c should be 21/3 rad, with two or 31 rad, and generally many times glad where n is the number of eccentrics that are lined on the rotor shaft. This eliminates the uncertainty of movement in the upper and lower rods and simplifies manufacture. The bushing surfaces of the bushings and the eccentric are anti-friction and lubricated by splashing the oil contained in the gear housing 3. The eccentrics 13 may contain an elastic ring that compensates for inaccuracies in the manufacture and installation of them on the shafts. The output shaft has flexible couplings that compensate for the possible misalignment of the shafts 5 and 11. The support collar 6 is equipped with mechanisms for adjusting the depth of processing. The machine works as follows: A torque is transmitted from the tractor's PTO shaft to the drive, and then to shafts 5 and 1 Together with shafts 5 and 11, the eccentricism 13 fixed on them rotates and the upper and lower bushings 15 and connecting rods 14 are driven back and forth. The lower bushings 15 transmit the force to the eccentrics of the shaft 11 and thus, together with the eccentrics, cause it to rotate. When the machine moves along the rut and rotates the cutter drum, its knives grind the soil or plant residues. Due to the presence of large contact surfaces between the sleeve and the eccentric, the specific loads on them and their wear are insignificant. The parts constituting the proposed mechanism are more technological than gears. The proposed technical solution is most effective for use in rotary tillage machines, in which for transmission of torque to the rotor shaft they use onboard transmissions with an intercenter distance between the driving and driving shafts of 500 mm. and more. The invention is supposed to be used in the modernization of the KFG-3,6 milling deep-ripper cultivator and the KFS-3,6 phrases containing 4-speed bend gears (with five spur gears), as well as appropriate when working on the PR-2 rotary plow 7 The economic effect only from reducing production costs is more than 600 thousand rubles. in year. Claim 1. Soil processing machine comprising a milling machine mounted on a horizontal shaft, a drive mechanism with an output shaft and a transmission mechanism, characterized in that, in order to ensure reliability, the transmission mechanism is designed as rigidly fixed on each of the shafts and installed with the same eccentricity and an angular displacement of at least two eccentrics, the opposing of which are mutually interconnected by connecting rods with bushings, which cover eccentrics. 2. The machine according to claim 1, characterized in that the magnitude of the angular displacement is a multiple of 7С / п glad, where n is the number of eccentrics locked on the shaft, Sources of information taken into account during the examination 1.
