Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rotary plucking device for a riding management machine, and in particular, the tilling claws are plucked up individually to increase the number of furrows depending on the crop planting method. This invention relates to a rotary flip-up device for a passenger management machine that is capable of changing.

[Prior Art] A rotary device of a conventional passenger management machine of this type is shown in Figs. 5 and 6 of the appendix. In Fig. 5, the lower link (2) and hinge (3) which are pivoted to the rear of the passenger management machine (1) are fixedly installed,
A rotary device (4) is locked to the hitch (3), and a drive shaft (5) of the rotary device (4) and a PTO shaft (6) are connected by a drive shaft (7). A frame (9) supporting a transmission shaft (8) is provided on the left and right sides of the drive input section (5), and a chain case Qo) is mounted on the frame (9) at a predetermined interval.
QΦ... are fixed, and each tilling claw Q+) is rotated by driving a chain (not shown) installed in each chain case θ0). After the tilling work is completed, as shown in Figure 6, extend the lift cylinder and rotate the lift arm 0→, lift the lower link (2) with the lift rod and move it to the rotary position. Raise the device (4).

[Problems to be Solved by the Invention] As described above, the rotary device (4) of the conventional riding management machine (1) simultaneously operates a plurality of tilling claws (tt)6t) by means of the transmission shaft (8).・It is rotated to perform work such as plowing.

Since each chain case (In) (10)... is fixed to the frame (9), the rotary device (4)
When flipping up, all of the tilling claws 00θ1)... rise at the same time.

However, the planting method differs depending on the type of crop. For example, cabbage and the like are usually planted in one row per row, while crops such as broccoli are planted in two rows per row. Therefore, when planting both crops, it is necessary to provide rotary devices that match the number of rows for each crop, which is extremely uneconomical.

Therefore, a technical problem arises that needs to be solved in order to form a rotary that can easily change the number of furrows without replacing the tiller depending on the crop planting method, and the present invention solves this problem. The purpose is to

[Means for Solving the Problems] The present invention has been proposed to achieve the above object, and is a rotary device detachably locked to the rear of a management machine, which In a rotary device, a frame supporting a transmission shaft is provided, a plurality of transmission means such as chains are attached to the transmission shaft at predetermined intervals, and a plowing claw is attached to each of the transmission means. and are separately rotatable around the transmission shaft, and each transmission case is provided with a protruding locking portion so that the locking portion can be fixed to the frame when the transmission case is flipped up, Pressure rods are provided on the frame at the same spacing as the conduction case, and when the conduction case is pulled up, the tip of the pressure rod is locked to the locking portion to bias the conduction case downward. It is an object of the present invention to provide a rotary lifting device for a passenger management machine having the following characteristics.

[Function] In the rotary device of the present invention, a transmission means such as a chain is attached to the transmission shaft, and a transmission case enclosing the transmission means has the following features:
Each of them is separately rotatable about the transmission shaft. When plowing is performed using all the tilling claws, all the transmission cases are pulled down and the tips of the respective pressure rods provided on the frame are locked in locking parts protruding from the transmission case.

Therefore, the pressure rod urges the conduction case downward, thereby preventing the conduction case from being accidentally thrown up during work.

On the other hand, when changing the number of furrows, the conduction case of the unused tilling claw is flipped up, and the locking portion provided on the conduction case is locked to the frame and fixed. Therefore, since no tilling work is performed at the part where the tilling claws have been sprung up, the ridge width becomes wider, making it possible to plant a different crop than in the case where all the tilling claws are used as described above.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4 of the attached drawings. For convenience of explanation, conventionally known technical matters will also be explained at the same time. Figure 1 shows a passenger management machine equipped with a two-point linkage mechanism, in which a lower link (21) 61) is provided in parallel at the rear of the passenger management machine, and a middle part of the lower link at) 61) is provided. The lower end of the lift rod (2) is pivotally connected.

The lift arm (2) (
2) One end of the lift arm is pivotally connected, and the other end of the lift arm is connected to the lift cylinder. In addition, a hitch (c) is fixed to the rear end of the lower link DI) and is engaged with a rotary device (to be described later), and a hitch (c) is fixed to a rotary device (to be described later), and is connected to a PTO shaft (to be described later) that protrudes from the rear of the engine. ) is connected to the drive input section (to) by the drive shaft (to).

Next, the rotary device will be explained with reference to FIGS. 1 and 2. On the left and right sides of the drive input section (to) are frames (
(To) A chain case (To) is provided to support both ends of the transmission shaft 01), and a chain case (To) is fixed to the negative side of the drive input part (1).
The PTO power input from the drive shaft is transmitted to the transmission shaft 00 via a chain (not shown). Then, a transmission means @@(2) such as a chain is provided at the center and both left and right sides of the transmission shaft 01), and each is covered with a conduction case (b) and OS (to), and each is placed around the transmission shaft 01). They are separately rotatably mounted. Locking parts (G) (2) and (1) are provided protruding from the upper rear surfaces of the central conduction case (B) and the left and right conduction cases (To). A notch is made to open the bottle hole 01).

On the other hand, in the center of the frame (1) (to), a hit frame member is fixed on the upper surface of the drive input member, so that it can be freely engaged and detached from the hitch (c) of the passenger management machine [phase]. is formed. Further, a locking piece (B) is fixed on the upper surface of the hitch frame (2), and one end of the pressure rod (A) is inserted and locked with a pin (41). The other end of the pressure rod is locked by fitting a bottle (41) into the bottle hole (B) of the locking part (2) protruding from the conduction case (B), and A spring (43) is inserted between the stopper (42) provided at an intermediate position of the pressure rod (4) and the locking piece (to).
) is inserted to urge the other end of the pressure rod (to) backward. Furthermore, a tilling claw (44) is pivotally attached to the lower end of the transmission case (b), and the rotation of the transmission shaft 01) is transmitted to the tilling claw (44) via the transmission means (2).

Further, the conduction cases (to) (to) provided on the left and right are also formed in the same way as the conduction case (b), and the conduction shaft (31)
The rotation is transmitted to the tilling claws (44H44). And the locking pieces (45) (4
5) is set upright, and one ends of the pressure rods (4B) (4G) are inserted and locked with the respective bottles (41) (41). The other end of the pressurizing rod (46) is locked by fitting a bottle (41) into a bottle hole (B) of a locking part (2) protruding from the conduction case (1), and locks the above-mentioned Just like the pressure rod (a) in the center, the other end of the pressure rod (46) is biased rearward by a spring (43).

(Thus, the second pressure rod (7) and (4B) (46)
Due to the suppression of ) (to) (g) to prevent it from bouncing up. Then, by pulling down all the conduction cases (B), (C), and (C), it is possible to till three rows at the same time, as shown in Fig. 2.

Next, the case where the conduction case (b) is flipped up as shown in FIGS. 3 and 4 will be described. As mentioned above, each conduction case (b), (g), and (to) are rotatable around the transmission axis (ell), but here we will explain the procedure for flipping up the central conduction case (b). First, insert the bottle (41) through the bottle hole (B) of the locking part (G) installed upright in the conduction case (B).
Remove the locking piece (to) and secure it to the hitch frame (to)
Pull out the bottle (4I) and remove the pressure rod (4).The pressure rod (4) is no longer suppressed and the conduction case (B) can now be rotated upwards as shown in Figure 11. Then, flip up the conduction case (B) and the tilling claw (44).At that time, the locking part (44) protruding from the conduction case (B)
) is inserted inside the hitch frame (to), and the bottle (47) is inserted through the side of the hitch frame (a) into the bottle hole (b) of the locking part (1) and locked, and the conduction case is secured. (B)
Fix it so that it does not fall. Therefore, as shown in Figure 4, the tilling claws (44) in the center are removed (the tilling claws on both left and right sides (
44) By using (44), it is possible to till two rows with wide ridge widths. To prevent danger, the tilling claw (44) in the center should be removed (or a clutch should be installed to stop the rotation) when hoisting.

Note that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to such modifications.

[Effects of the Invention] As described in detail in the above-mentioned embodiment, the present invention is configured such that the transmission cases enclosing the transmission means are individually rotated about the transmission shaft.

Therefore, rotate any conductive case and flip it upward,
If the locking portion protruding from the conduction case is locked and fixed to the frame of the rotary device, tilling work can be performed using only the tilling claws attached to a conduction case other than the conduction case. Since the lifting and lowering operations of the conduction case can be performed extremely easily, the number of ridges and the width of the ridges can be easily changed.

Therefore, it is possible to plant different types of crops using only the rotary device of the present invention without having to install multiple rotary devices each corresponding to the number of rows, which improves the work efficiency of tillage work and reduces the cost of the rotary device. This invention can also contribute to reducing down costs.
