点にある。[Detailed description of the invention] The present invention relates to a tiller in which a tilling device is connected to the tiller so that it can be adjusted up and down. It is possible to obtain a device with a simple structure that can quickly and reliably automatically correct the inclination of the tillage device and perform a good tillage work session without causing any variation in tillage depth in the left and right directions at all times. It is in the point of doing.

The tilling part cover assembly is divided into two parts at the center in the left and right width direction, and each part is pivotally attached to the tilling upper cover so as to be vertically swingable, and between the tilling upper cover and the tilling rear cover, A pair of left and right sensors are provided to detect the amount of rocking displacement of the rear cover of each tiller, and the left and right inclination of the tilling device relative to the ground is detected. It is characterized by being equipped with a posture control device that adjusts the left and right tilted posture of the tilling device with respect to the machine by individually changing the relative height positions of both left and right ends of the tilling device so that the tilling device becomes even or almost uniform. Therefore, even when the machine tilts from side to side due to getting into or riding over irregularities scattered in the field during tilling work, the divided rear part covers the rear part of the tilling device. The cover reliably detects the left and right inclination of the tilling device relative to the ground as the machine tilts.
The left and right tilling depths are uniform or almost uniform.

た。Since the tilling device can be automatically corrected in J:5, the tilling device does not continue tilling work while being tilted with respect to the field, and there is no constant noise in the tilling depth in the left and right directions. Although it is possible to perform plowing work without any problems, especially in the present invention, the detection device for detecting the left and right inclination of the tiller with respect to the ground is constructed by dividing the rear cover of the tiller. Therefore, compared to the case where swingable rod-like bodies are provided on both the left and right sides of the tillage device and the amount of rocking of the rod-like bodies is detected to detect the left-right inclination of the tillage device relative to the ground, a dedicated This resulted in the detection device being made unnecessary.

A tilling device 2 consisting of an upper tiller cover 10, a rear tiller cover 6 divided into two at the center of the width, which is attached to the rear end of the upper tiller cover 10 so as to be vertically swingable, and a top link 11 and a left and right pair. lower link 1
This figure shows an automatic tilling leveling device for a riding type cultivator, which is connected to the tiller automatically through a link mechanism consisting of 2° and 12 so that it can be raised and lowered. A pair of left and right sensors 3゜3 are provided to detect the amount of rocking displacement of the cover 6.6, and a sensor 3゜3 is provided between the pair of left and right lift arms 13, 13 provided at the rear of the machine 1 and the lower links 12, 12. In other words, the tilling depth of the pair of left and right becomes equal or almost uniform depending on the horizontal inclination of the tilling device 2 relative to the ground, which is determined from the difference between the detected values of both the sensors 3.3. A hydraulic cylinder of a posture control device 4 that adjusts the left and right inclined posture of the tilling device 2 with respect to the main machine 1 by changing the relative heights of both left and right ends of the tilling device Z separately so that the detected values of the sensors 3 and 3 are equal. 4A
