Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a seedling planting system that includes a seedling stand on which mat-shaped seedlings are placed, and a planting arm whose drive is intermittent by operating a planting clutch. The present invention relates to a rice transplanter in which a device is connected to a traveling machine body so that it can be raised and lowered.

[Conventional technology]

Conventionally, rice transplanters equipped with the above-mentioned planting clutch have been equipped with a lever for operating the planting clutch and a hydraulic pulp for raising and lowering the seedling planting device, as shown in Japanese Utility Model Application No. 56-108418, for example. When the lever is swung downwardly, the seedling planting device is moved downward, and when the lever is swung to the lower end, the planting clutch is engaged.

[Problem that the invention seeks to solve]

Normally, in the rice transplanting machine described above, to supply seedlings during operation, the machine body is stopped and the planting clutch is disengaged while the seedling planting device is maintained in a lowered state.
Therefore, if the operating lever is configured as in the above-mentioned example, the planting clutch lever will be located at the lower position in terms of operating feel, and even if the machine is driven with the intention of resuming work after replenishing seedlings, The operator may mistakenly believe that the planting clutch is in the engaged state. In particular, when the seedling planting device is installed at the rear of the machine, such as the running planter shown in the reference, it takes time for the operator to notice that the seedlings are not being planted, and improvements are needed. There's room.

The object of the present invention is that when the machine is driven with the intention of resuming work after replenishing seedlings, for example, the planting clutch is simply in a disengaged state, so that the seedling planting operation cannot be performed. 1. If this is not done, confirm this condition to the operator
The point is to get the configuration to do it.

Means for Solving Problem L] The features of the present invention are that the Sugaki rice transplanter is provided with a mechanism for detecting that more than a certain number of seedlings remain on the seedling stand, and that A mechanism for detecting the lowering state of the attached device, a mechanism for detecting the running of the machine body, and a mechanism for detecting the disengaged state of the planting clutch are provided, and the planting clutch is activated only when these V detection mechanisms are in the detection state at the same time. equipped with an alarm device that activates to request entry into the vehicle;
Its action and effects are as follows.

[For production]

For example, if the above characteristics are configured as shown in Fig. 1, if you intend to resume work immediately after replenishing the seedlings (W) in the middle of work, you may forget that the planting clutch Q4) is in the disengaged state. When the machine (2) is running, the limit switch υ detects the remaining amount of seedlings (W), the lowering state of the seedling planting device (A) is detected, and the Mituto Inchi detects the running of the machine (2). Since the sensor name and the limit switch that detects the disengaged state of the planting clutch H are in the detection state, these switches (2 phantom, (241, @ and sensor (c)
The output signal from will activate the voice message generator (2) via the AND gate (29).

〔Effect of the invention〕

Therefore, by simply adding electrical parts and wiring to the machine, the operator can recognize the disengaged state of the planting clutch even immediately after replenishing seedlings, reducing the occurrence of missing plants. The configuration was obtained.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 8, a five-row seedling planting device (
A) is connected to form a rice transplanter.

The seedling planting device (A) is connected to the transmission shaft (5) from the machine body (2).
) Driven by transmission case (6), mat-shaped seedlings (V/)
Seedling stand on which to place + 71, j planting arms (8) e
・.

It consists of three soil leveling flows 19), and as shown in Figure 2, the seedling planting device (A) is controlled to move up and down by following the unevenness of the drawing based on the ground pressure change of the central float (9). In order to perform be. This operating mechanism (B) is linked with planting clutch levers 0 to 10 which connect and disconnect the planting clutch θ, which is installed in the mission case haze of the fuselage (2) K.

That is, the planting clutch lever (05) and the planting clutch (14a) are interlocked and connected via a link (161, rod 07) and a coil spring (1 barrel).
Turn the lever (I5) into the operation range (ON) and the operation range (OFF).
), the planting clutch 04 is set to the engaged state and the disengaged state, respectively. Furthermore, when the lever Oa is set to the operating range (AUTO), the seedling planting device (A) is automatically raised and lowered, and when set to the position (W), the level is maintained during seedling planting work. When position (UP)K is set, the lever (
10 and the operating mechanism (B) are linked.

Therefore, when planting seedlings, set the planting clutch lever 06) to position (DOWN) K, and when stopping the movement of the machine (2) and replenishing seedlings (W), set the lever 06) to position (DOWN) K.
) is set to position (6) to maintain the automatic raising and lowering state of the seedling planting device (A).

In addition, in the center of the traveling aircraft 12), there is a boarding and operating section (C) equipped with a steering handle (I@) and a driver's seat (29).
The above-mentioned clutch lever (II9 is disposed on the side of the driver's seat) is formed. When this lever (1) is turned off and operated, the drive to the transmission shaft (6) is activated. is cut off.

In this rice transplanter, during work, if the worker forgets that the planting clutch Q4 has been disengaged and starts work immediately after replenishing the seedlings (W), it is possible to turn on the planting clutch. It is equipped with an alarm device that activates the request.

In other words, as shown in Figure 1, if there are seedlings (W) remaining for a certain amount of yield, the seedlings (
A rimming switch (211# (29)) that is pressed by the weight of V/) and turned off is provided, and when the link mechanism (A) is in the lowered state on the aircraft frame, the link mechanism (
An example of a mint switch is provided in which the arm device provided in A) is pressed to enter, and an axle (la) and a K gear (to) of the wheel il+ are provided, and a big amplifier is provided to detect the rotation of this gear (c). The running detection sensor μs consists of a device that counts the signal from this coil for a unit time.
, and set the planting clutch lever 061 to the off range (OFF
)K is set, a limit switch (2) is provided on the fuselage (2) that is operated by moving away from this lever (06), and a message generator (2) is installed which is activated by the output signal from the AND gate. Aircraft (2) K provided, this AND
Gate 01 has the limit switch (24+
, @, is configured so that the output signal from the sensor (c) is input.

Also, the switch installed on the seedling stand (7)? A NOT gate (support) for inverting the signal is interposed between υ and the AND gate. The message generator (2) then sends a message to the memory, D/D, etc. so as to emit a human voice such as "Insert the planting clutch" through the speaker.
It has a built-in A converter etc.

Embodiment C] In addition to the embodiments described above, the present invention provides a mechanism for detecting the running of the aircraft, for example, a switch that detects that the main clutch is engaged [6] and a shift lever that is operated to the forward position. It may be configured to detect this by performing an AND operation with a detection switch, and various other mechanisms can be implemented. In addition, the alarm device says, ``Please engage the planting clutch.''
It is also possible to construct a structure in which characters such as , etc. are drawn on a transparent plate, and the characters are made to stand out when a lamp is turned on.
