機に関する。[Detailed description of the invention] [Industrial application field] The present invention provides a rotary tiller, in particular, a rotary cover on the tiller body, and the transmission pipe casing of the rotary tiller is connected to the tiller body at a 360° angle.
This invention relates to a rotary tiller that can be fixed and rotated freely.
上述のロータリ耕耘機は、ロータリ耕耘装置を

For this reason, the rotary tilling device allows the operation of rotating the transmission pipe casing left and right with respect to the tiller body and fixing the position, and opening and closing the left and right cover portions of the rotary cover upwards depending on the respective tilling state. Each adjustment operation had to be performed separately, which was troublesome.

In order to solve the above problem, the rotary tiller according to the present invention is provided with a rotary cover having left and right cover parts that can be opened and closed upwardly on the tiller body, and a vertical transmission casing of the rotary tiller is attached to the main body. A rotary tiller configured to be rotatable relative to the rotary cover and rotatably fixed around its axis, and configured such that the direction of rotation of the rotary tiller shaft of the rotary tiller with respect to the casing is always constant. In this case, when the rotary tiller shaft rotates in the normal direction, both the left and right cover portions are closed, and when the rotary tiller shaft rotates in the forward direction, both the left and right cover portions open upward, and when viewed from above, the casing is in the left or right direction in the direction of movement of the tiller body. A cover opening/closing linkage mechanism is provided that operates in conjunction with the rotation of the pipe casing so that only the cover portion in the tilled soil scattering direction opens upward when the pipe casing is rotated to the right.

である。
In other words, due to the cover opening/closing linkage mechanism, when the rotary tilling shaft is rotating in the normal direction, both the left and right cover parts are closed, and when the rotary tilling shaft is in the reverse state, that is, when the pipe casing is rotated 180 degrees, the left and right cover parts are automatically closed. It opens upward and opens to the right (e.g. 45 degrees) in the direction of movement of the main body when viewed from above.
When the pipe casing is rotated, only the left cover portion automatically opens upward, and when the pipe casing is further rotated to the left, only the right cover portion automatically opens upward.
従つて、ロータリ耕耘軸の正転時における中耕
作業から左右方向への土揚げ或いは土入れ作業へ
の変更、さらには逆転時の土入れ作業への変更
を、本来必要な伝動用パイプケーシングの回動を
利用して自動的に行うことができる。
Therefore, it is possible to change from intermediate tilling work when the rotary tilling shaft rotates in the normal direction to lifting or putting soil in the left and right directions, or even to putting in soil when the rotary tilling shaft rotates in the reverse direction, without changing the originally required rotation of the transmission pipe casing. This can be done automatically using motion.
これによつて、各作業状態相互の切換えを迅速
に行い得て、作業能率を高めることができた。 This makes it possible to quickly switch between the working states and improve work efficiency.

ようにされている。 The rotary tilling shaft 8 of the rotary tilling device 5 employs a drive system that is always driven in a constant direction. Reference numeral 9 denotes a rotary cover, which is fixed to the main body 1 and includes left and right cover parts 9a and 9b that can be opened and closed upward about an axis parallel to the direction of movement of the main body. 10 is the left and right cover portion 9a,
This is a left and right cover vertical opening/closing mechanism that opens and closes the left and right covers 9b upward. This opening/closing mechanism 10 has five parts when viewed from the front.
It has a rectangular link structure, and as shown in FIGS. 1 to 5, the left link arm 10a is pivotally connected to the left cover portion 9a, and the right link arm 10b is pivotally connected to the right cover portion 9b. has
A long hole is formed at the other end of these link arms 10a, 10b, to which connecting arms 10', 10b' are connected slidably and bendably, and each of these connecting arms 10a', 10b' The other ends are pivotally connected to each other by a single connecting pin 10c. This pin 10c is operatively connected to a cover opening/closing linkage mechanism 11, which will be described later. Therefore, due to the pentagonal link structure, the movement of the pin 10c is as follows:
It is possible to move not only vertically but also horizontally, so that when the connecting pin 10c is moved upward beyond the flexibility of the elongated hole, both the left and right cover parts 9a and 9b open upward (the first 5), only the left cover portion 9a opens upward when moved to the right, and only the right cover portion 9a opens upward when moved leftward (FIG. 4).
Reference numeral 11 denotes a cover opening/closing linkage mechanism, which, as shown in FIGS. 1 and 2, includes a rod 13 pivotally connected to a guide 12 protruding from the pipe casing 6 so as to be relatively rotatable; , a holding member 13' slidably penetrated near the other end side, an L-shaped crank 14 having a long groove into which a pin 13a protruding from the holding member 13' is engaged, and this L-shaped crank 14. A crank support 15 is provided to swing around a longitudinal axis P 2 perpendicular to a horizontal axis P 1 , and when the rod 13 is pulled due to the rotation of the pipe casing 6, the rod 13 is In order to move horizontally, this rod 1
a crank member 13b provided so as to be relatively swingable between a substantially intermediate portion of the main body 1 and a frame portion of the main body 1;
The left and right cover vertical opening/closing mechanism 10 has a connecting pin 10c connected to the other end of the L-shaped crank 14. The rod 13 has a curved shape 13c corresponding to the outer shape of the pipe casing 6.
It is designed so that it can follow the 180 degree rotation of the pipe casing 6 (however, only rotation in one direction).

When it is rotated 180 degrees and enters the reverse state, it engages with the L-shaped crank 14, swings the crank 14 forward about its swing axis P1 , and both the left and right covers 9a and 9b are moved. It is configured to open upward. Further, the crank support 15 is arranged such that its swing axis P 2 (front-back axis) is perpendicular to the longitudinal axis of the pipe casing 6 in the traveling direction when viewed from above. , thereby being regulated by the crank member 13b,
By using the action of horizontally swinging the rod 13 as the pipe casing 6 rotates left and right, the shaft center
