Embodiment Construction

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0033] exist figure 1 In to 4, a tractor 1 has front wheels 2 and rear wheels 3, each front wheel 2 is controlled by a steering rod handle 5 in front of the driver's seat 4. The tractor 1 is equipped with a side-driven rotary cultivator 8 through the lower pull rod 7 . A gearbox 9 is provided at its center, and a drive shaft 10a with a universal joint protrudes forward from an input shaft 9a located at the gearbox 9 and is connected to a power output shaft 10 of the tractor 1 to thereby transmit power. Each crossbeam 11 protrudes laterally from both sides of the gear box 9, a support plate 12 is fixed on the middle part of each crossbeam 11, and a pivot pin protrudes from the front end of the support plate 12 for pivotably supporting the pull-down rod 7, The support plate 12 pivotably supports the front end of a depth frame 13 at its rear end, ...

Abstract

The invention provides a rotary cultivator constructed to enable a cultivating work at high speed. The cultivator comprises a plurality of cultivating claws provided on a cultivating claw shaft for performing cultivation on the same cultivating line in a farm land, said each cultivating claw being provided such that its path of movement overlaps lengthwise under ground surface. Further, a plurality of cultivating claws are provided in a plurality of rows on the same plane perpendicular to the cultivating claw shaft of the rotary cultivator such that the respective cultivating claws in each row are curved leftward or rightward so that cultivation is done with large spaces kept between tip ends of the opposing cultivating claws. Cutting blades are provided between the predetermined cultivating claw rows to cut lumps of earth during cultivation.

Description

technical field [0001] The present invention relates to a high-speed rotary cultivator for cultivating at high speeds, and more particularly to a rotary cultivator capable of changing the number and arrangement of the cultivating claws of the rotary cultivator and the cultivating claws The number of revolutions of the shaft increases the tilling speed, which is expected to reduce the tilling work time. Background technique [0002] Generally, the rotary cultivator is attached to the rear of a stretcher or a motorized cultivator for cultivating operations. However, tillage is tedious, and when plowing a large field or contracting tillage, it is often desirable to end it as soon as possible. [0003] Therefore, when the operating speed becomes high, although the working speed is increased, it is inconvenient that the tilling pitch becomes large so that it is impossible to realize a uniform tilling work. [0004] In order to eliminate the above inconvenience, a PTO transmissi...
