Description

[Detailed explanation of the invention] This invention is based on the method of reciprocating planting by drawing lines to form a line mark on the surface during the operation, and the next planting to form a linear mark on the surface that will serve as the machine running reference during operation. The present invention relates to a rice transplanter in which markers are mounted on the left and right sides of the machine body so as to be switchable between a working position and a non-working position.

When considering the work involved in reciprocating planting, the markers attached to the left and right sides of the machine act on the ground side when not planting to avoid disturbing the already planted seedlings, and mark linear marks on the seedlings. Planting is done on the surface, but when the planting is completed to the end of the planting row and the aircraft is turned, the side of the aircraft that was not planted on the leading pole and facing the ground will be reversed. Since the planted type faces toward the ground, when the aircraft is rotating, one of the left and right markers that is in the active position is changed to the non-active position, and the other marker that is in the non-active position is changed to the non-active position. It is necessary to change the position of the marker to the active position.

In other words, when planting in a reciprocating manner, the left and right markers are used alternatively.

However, in models where the operator directly manually operates the markers to change the posture when the machine rotates, especially in multi-row riding type rice transplanters, the worker manually operates the left and right markers each time the machine rotates. This requires a very troublesome switching operation, and the marker itself is large and heavy, so it has the disadvantage of requiring a great deal of effort on the part of the operator.

Therefore, in the past, attention was paid to the alternative usage of the left and right markers, and the left and right markers were linked to each other so that when one marker was changed to an active position, the other marker operating mechanism was set to a non-active position. To some extent reduce the effort required to change the attitude of the markers by configuring the aircraft so that the attitude can be changed by only changing the attitude of the left and right markers when the aircraft is turning.
Alternatively, as shown in Japanese Utility Model Application Publication No. 48-28927, by linking the middle part of the wire that interlocks the left and right markers to the rice transplanting mechanism via a reversible interlocking mechanism, the left and right markers can be selectively connected. Techniques related to the operation structure are known in which switching between working and non-working postures and obtaining simultaneous non-working postures for both markers is known, but in the former case, one of the left and right markers is always in the working posture. Because of this, when the aircraft rotates, this working posture marker may accidentally disturb the ground side while planting seedlings on the surface, and planting seedlings may not only disturb the posture. , the marker in the working position collides with the ridge of the field,
In the latter case, when both markers are in the non-active position, the non-active position is set to the middle of the marker's swing range. Since the marker is not equipped with a structure to stably maintain its posture, the marker may wobble due to machine vibration or vertical movement of the machine when moving over a highly uneven plowing platform near the edge of the field. In addition, because the tip of the marker is far from the aircraft and the tip is not high enough, it may get caught on trees near the ridge or supply seedling boxes on the ridge. This could easily lead to inconvenience.

The technical problem to be solved by the present invention is that it is possible to selectively switch the left and right markers into an active position and a non-active position, and also to simultaneously set both markers to a non-active position. Rather than manually performing this operation for each marker, non-planting, such as when the aircraft reaches the edge of the field and performs a roundabout, is automatically performed according to the operation of the operating tools used during work. In order to make this possible, the posture of the marker must be switched between only two positions, the working position and the non-working position, and when changing the posture of one marker, it can be done without affecting the other marker. It can be operated and maintains the posture of the other marker in a stable position.

Furthermore, another technical problem is that in a rice transplanter equipped with a planting device section that is equipped to move up and down with respect to the passenger aircraft, when the height of the planting device section relative to the aircraft body is changed, linear markings using markers The goal is to be able to draw at an appropriate depth without being too shallow.

The technical means of the present invention taken to solve each of the above technical problems is that a linear mark is formed on the surface of a passenger aircraft for planting seedlings, and a line marker is formed on the surface of the passenger aircraft. The rice transplanter is equipped with a seedling planting device which is equipped to be able to move up and down on a seedling planting device, and which is attached to the left and right sides of the seedling planting device so as to be able to switch between two positions, a working position and a non-working position, respectively, and each of the markers The marker operation mechanism is used to independently switch between working and non-working postures. In addition, the marker operating mechanism is connected to an operating tool such as a planting clutch operating lever that is operated by reciprocating operation in a straight line.
A posture holding device is provided that fixes and unfixes each of the markers in a non-working posture, and both markers are made inactive in conjunction with a work-related operation of the non-planting H before the machine rotates using the operating tool. The operation of the posture holding device is controlled so that the operation of the operating tool is released, and as the operation of the operating tool is released, one marker is tilted left and right, or one marker is maintained in a constant non-operating posture while the other marker is activated. A switching mechanism is provided for selectively switching and controlling the posture holding device so as to maintain the posture.

The effects of the above technical means are as follows.

■ Non-planting is when the left and right markers are selectively put into the working position and the non-working position, and both markers are put into the non-working position at the same time as the operating tools are inevitably operated in connection with the work. Although it is possible to automatically switch the posture, each marker can switch the posture by a marker operation mechanism that operates each marker separately, so the posture switching operation of one marker changes the posture position of the other marker. There is no risk of the marker being placed in an unstable position, such as moving the marker to the middle of the swing range. When switching to the working position, both markers or the other marker are held fixed in a stable, constant non-working position, so there is no problem such as the marker wobbling or the tip of the marker falling down and coming into contact with other objects. This has the advantage of reliably avoiding this.

■ As the operating tool linked to switch the posture of each marker, an operating tool is used that performs the necessary operations related to the planting work by reciprocating operations in a straight line. For example, compared to the case where the operating tool is linked to an operating tool that is operated two-dimensionally along a cross-shaped or H-shaped guide groove, it is easier to change or check the operating tool position each time the marker posture is changed. It is also advantageous in that there is no need to perform operations from the beginning, and once you intuitively memorize the location of the operating tools, you can easily change the marker posture as desired by simply repeating the reciprocating motion. be.

■ Since the marker is attached not to the passenger aircraft, but to the planting device that moves up and down relative to the passenger aircraft, it is possible to change the planting depth according to changes in the plowing depth, etc. Even if you change and adjust the height of the planting device relative to the aircraft, the height of the marker relative to the ground will be automatically adjusted accordingly, and therefore the amount of sinking of the aircraft due to the shallowness of the plowing platform will change. However, the linear mark made by the marker is easy to draw clearly and at an appropriate depth.

Hereinafter, embodiments of the configuration of the present invention will be described based on the drawings.

Figures 1 and 2 show a 6-row planting type riding rice transplanter.
This rice transplanter has a pair of left and right running wheels 2 at the front and rear positions, respectively.

And via the spring 8, the six-row seedling planting device 5 can be raised and lowered freely, that is, the planting that slides on the mud surface can be switched up and down between the working state and the non-working state where the planting is located high on the mud surface.
In addition, the planting is placed so that it can move up and down to follow the unevenness of the mud surface in the working state, and a linear mark A is attached to the surface for planting seedlings, which serves as a running reference for the machine during work.
By swinging the letter-shaped line-drawing markers 1 and 1' on the left and right sides of the seedling planting device 5, respectively, around the horizontal axis R2, the working position is such that the tip thereof plunges into the mud surface, and The tip is configured and mounted so that it can be freely switched between two positions: a non-working position located above the horizontal axis R and R'.

The seedling planting device 5 includes a seedling platform 5 that is movable laterally and reciprocally on a frame A that is supported by the body frame 4 so as to be able to rise and fall freely.
At the same time, the seedlings placed on the seedling stand 5a are taken out in unit quantities and planted.6
A claw 5b for taking out and planting the seedlings and a soil leveling body 5c for leveling the muddy surface of the planned location for planting are provided.

When the aircraft reaches near the edge of the field, the planting operation is temporarily suspended, and the aircraft resumes the planting operation after making a circuit, but this type of non-planting work The planting clutch operating lever 9, which is an example of an operating tool that is necessarily operated in connection with the rice transplanter and is operated by reciprocating operation in a straight line, is placed near the operator seat 3 of the rice transplanter. The control lever 9 is configured to control the planting operation of the seedling planting device 5 by turning on and off the operating lever 9, and also to control the marker operating devices io and io', which will be described later.

The switch mechanism 11 is operated by the operation lever 9, and when the operation lever 9 is operated to the latch release side, the two-position switching circuits 10a, 10
b are both closed to energize the solenoids of the two attitude holding devices s and s', and by operating the operating lever 9 to the clutch engagement side, the two attitude switching circuits 10a and 10b are activated.
The structure is such that the solenoids of the posture holding devices S and G are sequentially and selectively deenergized by opening the solenoid alternately.

Therefore, in the rice transplanter configured as described above, non-planting is always performed before the machine starts rotating during work. 1') to a non-working position, and both markers 1 and 1' are set to a non-working position. Marker (1 or 1') corresponding to the above-mentioned working position is attached by clutch engagement operation.
The marker (1' or 1) located on the opposite side of Although it is possible to reliably maintain the non-working position of , 1', it is also possible to easily form marks on the ground side mud surface when not planted, and to use as a driving reference when planting the next time. .

In addition, if you are forced to disengage the clutch during planting due to replenishment of seedlings while driving, the marker on the opposite side (1 or 1') will be in the active position when the clutch is disengaged. To plant again, disengage the clutch and then engage the clutch.
