Abstract

Avoids wasteful power consumption when changing the scribing marker of a farming machine such as a rice transplanter from a standing position (not drawing) to a lowering position (drawing status) of the scribing marker. The working part of is not to be damaged by touching the interference.

At the same time as the work of the agricultural work installed on the traveling vehicle progresses, the operation of changing the scribing marker to the scribing position by the actuator is done by draping the topsoil surface of the field where the gas passes in the next stroke. Even if the scribing marker does not change to the scribing position because the scribing marker interferes with the interference, it is a method of scribing a farm implement which repeats the operation by stopping the operation of the actuator once and then reactivating it after a predetermined time.

On both left and right sides of the front part of the traveling vehicle 2, preliminary mother mounting tables 77 in which mother mounting portions 77a are formed in multiple stages are provided. When remaining, the hair loaded on the spare hair mounting table 77 is picked up and supplied to the hair mounting table 42.

On both left and right sides of the traveling vehicle body 2, a scribing marker 80 which draws a position on the topsoil surface at which the left and right centers of the body pass in the next stroke is provided. The scribing marker 80 is supported by the support frame 29 supported by the front wheel final case 11 about the pivot shaft 79a in the front-back direction of the marker frame 79, and the The base portion is freely rotatable with the pivot shaft 81 in the up and down direction as a point, and the bending action portion 83 is bent freely by bending the actuation portion 83 of the marker arm 82. Position (acting position) in which the marker arm 82 extends in a horizontal shape so that the tip end thereof is grounded, and both positions (non-acting positions) or the storing position where the marker arm 82 stands up upwards. Position).

When the gas is advanced in the state where the scribing marker 80 is lowered to the acting position, the scribing acting portion 83 scrapes the topsoil surface hard and draws a line. In the next stroke, the gas is advanced while the steering wheel 23 is operated so that the trajectory of the line coincides with the center mascot A visually.

Moreover, as shown in the side view of FIG. 3 and the top view of FIG. 4, the drive of the scribing marker mechanism was made into an electric motor drive type. In the configuration of the electric marker shown in FIGS. 3 and 4, the marker frame 79 is supported on the support frame 29 so that the marker frame 79 can be accommodated in the horizontal direction manually along the side of the body. It has the structure which can be bent, and the marker arm 82 is bent by the marker motor 89 at the tip of the marker frame 79, and the bending is freely connected.

The marker frame 79 is provided with a bracket 88 on the acting portion, the marker motor 89 is installed on the bracket 88, the pinion 90 and the marker arm 82 installed on the rotating shaft of the motor 89. Is engaged with the circular gear 91 provided in the base portion of

In addition, by the rotation of the gear 91, the marker sensor 92 provided in the bracket 88 can detect the amount of rotation of the marker arm 82, and the horizontal position at which the marker arm 82 is a scribe position. The rotation of the marker motor 89 is stopped at the time when the movement is completed, while the marker arm 82 is raised to a dotted line position (marker unmarked position) or one dashed line position (marker storage position) in FIG. After moving the marker arm 82, the marker arm 82 can be stopped.

In addition, the control of the rotation amount of the marker arm 82 to the storage position (a dashed-dotted position) of the marker arm 82 is a side view (bracket 88 and the marker motor 89) of the action part of the marker frame 79 of FIG. (Not shown), a marker storage sensor 93 made up of a pair of proximity sensors 93a and 93b provided at each end of the marker frame 79 and the marker arm 82 can be used. When the marker arm 82 rotates to the storage position indicated by the dashed line, the pair of proximity sensors 93a and 93b are in the closest position. At this time, the marker storage sensor 93 is in the ON state. It can be seen that the marker arm 82 is rotated.

The rotation of the marker arm 82 to the marker line position or the marker storage position may be achieved by using a motor capable of detecting the output rotation amount of the marker motor 89 or by outputting an output signal from the controller 97. It can also carry out by controlling. In addition, a program is performed to control the marker arm 82 to move to the marker storage position or the position where the marker line is not drawn.

In addition, when the marker arm 82 rotates to the storage position, an electric circuit or electric program control may be configured to prohibit the movement of the marker arm 82. This is because the marker arm 82 moves up and down without preparation, which may damage the scribing marker 80 and the gas.

Although FIG. 6 shows a block diagram of the drive control device for the scribing marker 80 as shown in FIG. 3 and FIG. 4, the elevating ring device for attaching and lowering the steering sensor 94 and the seedling unit 4 ( 3) Lifting ring sensor 95 for detecting the lifting position of the detector arm and a pair of left and right marker sensors (potentiometers) 92R and 92L for detecting the marker arm 82 and a pair of left and right marker storage sensors 93R and 93L (one pair each) Of the left and right marker arms 82R, 82L by the proximity sensors 93a, 93b) of the left and right marker motors 82R, 82L are controlled by the controller 97.

FIG. 7 illustrates the case where the acting portion 83 or the like of the scribing marker 80 touches an interference object such as a furrow shown in FIG. 9A during the scribing set operation from the marker storage position of the marker mechanism of the agricultural work machine to the scribing position. The flow of operation control of the marker motor 89 is shown. For the sake of simplicity, a mechanism for driving control of the marker motor 89 shown in FIG. 6 by the control apparatus 97 will be described.

When the acting portion 83 or the like of the scribing marker 80 touches an interference object such as a field, the marker sensor 92 detects the marker sensors 92R and 92L despite the output signal to the marker motors 89R and 89L. Since there is no change in the value, it can be determined that the marker motor 89 is in the locked state (there may be a method of detecting the current value to the marker motors 89R and 89L and determining the locked state). In this case, the setting operation to the scribing position of the marker mechanism is stopped. After 5 seconds has elapsed, the set operation is repeated. At this time, if the number of re-outputs exceeds the upper limit, the set operation of the marker 80 is stopped. If the number of re-outputs is less than the upper limit, the set of markers 80 is reactivated.

In this way, the wasteful operation when it is desired to partially set the scribing marker 80 in the deformed field near the crotch is stopped, saving power consumption and preventing damage to the scribing marker 80. .

In addition, as shown in the flow of FIG. 8, in the position control of the electric scribing marker 80, when the lock state is detected during the set operation of the scribing marker 80, the set output is stopped once to return to the marker storing state. The value of the marker sensor 92, that is, the height of the scribing action portion 83, can be set at the same time as to determine whether to output or set output again.

In the case of the flow of FIG. 8, when it interferes with obstacles (walls, etc.) other than the field of FIG. 9 (b), when the line drawing part 83 is close to the base and becomes locked at a high position, the scribing marker 80 is broken. Can be prevented. In the flow of Fig. 8, the marker storage part operation and its stop can be performed by turning ON / 0FF of a marker switch (not shown).

In addition, when the worker intends to release the marker storage state, if the release means for releasing by the operation of an operation tool such as a marker switch (not shown) or the lifting / lowering operation of the seedling base unit is provided, the storage of the scribing marker 80 is unnecessary. Nevertheless, the scribing marker 80 can be set and output again, such as when malfunctioning or avoiding obstacles other than a field or the like.

In the position control of the electric scribing marker 80 by the flow shown in FIG. 7 or 8, when the scribing marker 80 on the left side is corrected during the set operation, for example, with the marker set position correction switch, When the correction amount is stored and the right line marker 80 is set after the rice transplanter is rotated, the right line marker 80 can be set at the corrected position.

This is because after straightening the rice transplanter, the fields with the same hardness and soil depth are drawn, so that the set position of the scribing marker 80 can be corrected to improve workability. have.

In addition, if the set position correction switches of the scribe markers 80 on the left and right sides are provided, the set operation of the scribe markers 80 can be made to correspond to the inclination of the field at the time of draping the slope.

According to invention of Claim 1 of this invention, the waste of operation of the actuator 89 can be prevented, and the damage of the scribe marker 80 can be prevented.

In addition, according to the invention of claim 2, in addition to the effects of the above-mentioned claim 1, the wasteful switching operation of the scribing marker 80 can be stopped, thereby preventing damage to the marker 80 and saving power. .

According to the invention of Claim 3, in addition to the effect of Claim 1, the wasteful switching operation of the scribing marker 80 can be set to an appropriate number of times suitable for each environment, so that the marker 80 is broken. Prevention and power saving can be achieved further.
