Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to improving the matte-colored seedlings placed on a direct-loading stand to prevent the matt-colored seedlings from slipping down toward the seedling outlet. The seedling stay is configured to be able to move up and down, switching between an active position in which it presses against the seedlings, and a non-active position in which it moves away from the matte color when the vertical feed mechanism operates to feed out the matte color towards the seedling take-out port. The present invention relates to a bacterial seeding device comprising:

[Conventional technology]

In this type of seedling planting device, the seedling stay is retracted to a non-working position by the cutting action of the vertical feed mechanism. Conventionally, a seedling feeder protruding from the surface of the bacteria is used for vertical feeding. There was a device in which the rotary drive shaft and the drive arm for changing the posture of the seedling stay were interlocked and connected by a connecting rod, so that the posture of the germ stay could be changed to the non-working posture only when the vertical feed mechanism was activated. (For example, Tokuko Sho 57-22285
Publication No.).

[Problem that the invention seeks to solve]

However, if we were to incorporate a single row clutch that separately drives and stops some of the multiple planting mechanisms into such a conventional structure, it would be possible to simply have both of them coexist. In this case, even if each row clutch is operated and the corresponding planting mechanism is stopped, the vertical feed mechanism is configured to operate integrally over all rows, so the individual row clutch is activated. Since the vertical feed mechanism will repeatedly stop operating even in the friend planting row when the seedling stay is turned off, the seedling stay will switch its posture between the working position and the non-working position each time.

Therefore, the bacteria will repeatedly press against the same part of the matted sprouts that are in a state of cessation, which will damage the matted bacteria, which is unfavorable in terms of planting work.

The purpose of the present invention is to provide a system that can solve the conventional problems and suppress mechanical damage to the planting nails by providing a rational interconnection mechanism between each row clutch and the fungus stay. At the point.

[Means for Solving the Problems] The characteristic configuration of the present invention includes an active position in which the matted sprouts placed on the sprout placement table are pressed onto the seedling placement surface, and a non-active position in which the matted sprouts are separated from the matted sprouts. The bacteria stay, which is configured to be able to move up and down, is changed to a non-working position in conjunction with the cut-off operation of the vertical feed mechanism that feeds mat-shaped seedlings toward the seedling take-out port, and also in conjunction with the stop of the vertical feed. to return to the working position
, #-type seedling spraying device, when the planting claw that attaches the seedlings taken out from the seedling take-out port to the rice field surface is located above the rice field surface, a part of the plurality of planting mechanisms is individually driven. The structure is such that each row clutch to be stopped is disengaged, and the seedling stay corresponding to the stopped row is held in the operating position in conjunction with the operation of each row clutch, and the operation is The effects are as follows.

[For production]

In other words, the corresponding seedling stay can be maintained in the working position by the disengagement action of each row clutch, so there is no change in posture with respect to the mat-shaped seedlings, and it is possible to prevent the "knocking" phenomenon on the same part of the mat-shaped cup. It can prevent seedlings from falling off.

Moreover, the timing for disengaging this individual row clutch is only when the planting claw is located above the field surface.
The planting mechanism does not stop when the planting claw enters the projection surface.

〔Effect of the invention〕

When each row clutch is disengaged, the seedling stay is in the working position, so the front surface of the lower end of the mat-like seedlings slides down along with the sliding plate of the bacteria platform, and that part comes into contact with the sliding plate. It prevents the mat-like bacteria from rising in an arc shape, allows smooth vertical feeding of the mat-like bacteria, and suppresses the knocking phenomenon on the mat-form seedlings, so the mat-form seedlings are not damaged and can be taken out with the planting claw. can also be done reliably.

They are interlocked and connected via 351. A3 in the figure is a drive cam for changing the posture of the seedling stay, which will be described later.

The vertical feeding mechanism (toward) that feeds out the mat-like seedlings 181 toward the germ removal port (6A) of the seedling stand (6) will be described in detail.

A seedling feeder (7) that protrudes from the seedling feeder (ILl) and feeds out the mat-like seedlings IB+ toward the sprouting port (6A) is connected to a hexagonal shaft (7) supported so as to be able to operate independently for every two planting rows. (b), and a one-way clutch (to) and a return spring bend are attached to each hexagonal shaft α7).

Below the hexagonal shaft α, there is rotatably provided an operating shaft supported by a seedling stand (6), and a passive arm f2 extending from the one-way clutch is connected to the operating shaft σ].
11 and the transmission arm (24+) fitted into the transmission arm (24+), which is brought into contact with and swung by the drive piston material described later at the end of the horizontal sliding stroke of the bacteria platform (6). The material c!31 is pivotally supported on the planting r-s (2) so that it can slide in the direction of its own axis (Z), and
) A bi-shaped contact portion (23a) is attached to the outer tip of the r-s (2) so as to urge the inner tip to come into contact with the cam surface of the posture switching drive cam (to), and the transmission arm An example is constructed so as to swing in contact with each other. Said one-shaped contact part (23a)
The paired transmission arm @contact surface (23b) is for planting 1-s (2

Despite the adjustment, the positional relationship between the two-shaped contact portion (23m) and the transmission arm 1241 remains unchanged.

As shown in Fig. 4, ■ in the figure is a frame that interlocks and connects the shaft end of the spiral shaft tube that controls the lateral sliding movement of the 100-nose stand (6) and the seedling stand (6). be. Further, the helical shaft @ is housed in a simple shaft (2) which is transmitted to the transmission shaft (11) by a bevel gear, and is configured to be able to slide laterally in the axial direction by a piece member (3) that engages with the helical groove.

Next, Moe Stay αhiro will be explained in detail. A horizontal connecting rod c111 to which two long presser feet and four short presser foot rows are attached is pivoted to both end platforms @, ■,
Both end brackets ■, ■ are connected to the connecting rod (2) on the inward side, and the next arm ω is arranged, and this arm ■ is artificially connected to the connecting rod (2) with the center of the axis of the connecting rod (to). It is configured so that the swing position can be changed with respect to the plagets at both ends.

It is possible to change the posture of the plant to a large extent, and it is effectively used when replenishing seedlings. The above items are provided as one set for each two planting rows. The pradet (2) at both ends is fitted onto the operating shaft (a) and interlocked with the swinging arm (to) so as to be able to move relative to it, and the presser (support) is operated by the cutting action of the drive piston member. It is changed to a non-working position in which it is spaced upward from the mat-like seedling tBl, and is changed to an active position in which it presses the mat-like seedling IB+ onto the seedling 11L) by stopping the cutting operation of the driving piston member.

From the above configuration, the kAA piston member 231 always slides when in contact with the posture switching drive cam (rotation).
At the end of the reciprocating sliding stroke of the moe pedestal (6), the transmission arm C fitted on the operating shaft is swung to rotate the operating shaft.
By rotating the oscillating arm, the oscillating arm is actuated, and the bacteria stay is retracted to a non-operating position via the blades ① and ② at both ends of the oscillating arm.

On the other hand, due to the rotational operation of the operation described above, the drive arm C21 is rotated at the time of the drive arm C21, and after the device remains for a certain period of time from the upward movement of the bacterial stay Q4), the passive arm t2 is
1+ to rotate the moe feed brass. After the Hyakusaka feed, the driving piston member (23) retracts and the moe step 204) returns to its working position. If the clutch (9) is operated under such normal conditions, the power transmission to the sprodet (lυ) will be cut off.Therefore, the cutting action of the drive piston material will be stopped, and the bacteria stake will be cut off. The switching to the non-operating position is prevented, and the even cutting operation of the continuous feeding mechanism a is also stopped.

As shown in FIG.
The installation phase of the recess (lla) in A) and the replacement drive cam head in the above-mentioned position is such that the dedicated piston material is retracted and the clutch operating piece engages with the recess (11a) with a rounded center. ,
With each row clutch disengaged, the moe stay Q-it is maintained in the pressing posture, and in this each row latch release phase, the planting claw (3) is set in phase (P) as shown in Fig. 5. By matching the recessed portion (11m) and the grooved claw phase to limit the range shown, the planting claw (3) can be stopped above the rice field in the state of each row clutch (9).

The operation range (Q) of the planting claw (3) shown in the figure is the range in which the vertical feed mechanism (to) operates.

[Another example]

The vertical feed mechanism αQ may be configured to operate as long as the hundred stay α→ is switched to the pressing action state I by the disengagement operation of each row clutch (9).
