Description

[Detailed Description of the Invention] The present invention relates to a supporting rod interlocking structure for a line drawing marker in a seeding section of a submerged direct sowing machine.

Conventionally, in flooded direct seeding machines, a center marker is arranged in front of the driving section on the center line of the traveling machine, and support rods are provided that protrude from the traveling machine on both sides or from the sowing part at a fixed length on both sides. A line marker is placed at the tip, and when sowing, while running on the field surface, scratch the field surface with the line marker to draw a mark line, then turn back at the edge of the field and run. The row alignment is performed by aiming at the landmark line with the center marker. However, direct sowing by flooding, in which the sowing section is connected to the front or rear of the traveling machine so that it can be offset to the left and right sides, for example, so that the rear of the wheels of the traveling machine and the trench cultivation part of the sowing section do not coincide, is possible. In case of a structure in which a line-drawn marker is arranged at the tip of a support rod that protrudes at a constant length from both sides of the traveling machine body or from both sides of the sowing section, if the sowing section is offset, the line-drawn marker will not be used. The drawn mark line does not serve as an aim for the center marker, and a separate adjustable line marker must be provided for offset, making the structure complicated.
In addition, the line marking marker has to be adjusted every time, making the seeding work complicated.

In this invention, a marker support rod that is slidable to the left and right sides is horizontally supported in the seeding section, and left and right line drawing markers are connected to both ends of the support rod, respectively, and are connected to the left and right sides of the seeding section via an interlocking mechanism. When offset,
By configuring the marker support rod to be able to slide separately from the seeding section by the same distance as the offset distance in the offset direction, the left and right line drawing markers automatically move appropriately during offset,
To provide a supporting rod interlocking structure for a line-drawing marker in a sowing section in a flooded direct sowing machine, which allows the mark line drawn with the same marker to be used as the aim of the center marker and to align the rows without adjustment, making it extremely easy to sow. That is.

The embodiment of the present invention will be explained in detail based on the drawings.
A indicates a flooded direct sowing machine, and this flooded direct sowing machine A
The sowing section 3 is connected to the rear of the traveling machine body 1 via the connecting section 2.
are connected.

The traveling body 1 has a prime mover section 5 at the front and a driving section 6 at the rear on the upper side of the body frame 4, and a center marker 7 is erected at the center of the body in front of the driving section 6. On the sides, front wheels 8 are arranged on both sides of the front part, rear wheels 9 are arranged on both sides of the rear part, and at the rear of the fuselage frame 4, upper arms 10 are arranged on both upper sides and lower arms 11 are arranged on both sides of the lower part. The front and rear wheels 8, 9 are driven by the power of
The sowing unit 3 is configured to be raised and lowered by the raising and lowering operation of the sowing unit 3.

The connecting portion 2 includes an intermediate bracket 12 connected to the tips of the upper arm 10 and the lower arm 11, and a rear bracket 1 disposed on the rear side of the bracket 12.
3, with left and right parallel link arms 14, 15 interposed between the middle bracket 12 and the intermediate bracket 12. supported. In addition, a seeding bracket 16 is connected to the rear side of the rear bracket 12 and connected to the front central part of the seeding section 3. Left and right parallel link arm 1
4 and 15 respectively connect the front end to the intermediate bracket 1.
The seeding section 3 is pivoted vertically on the left and right sides of the rear bracket 13, and its rear end is pivoted vertically on the left and right sides of the rear bracket 13, so that the seeding section 3 can be offset to the left and right sides.

The seeding unit 3 has support stands 18 erected on four floats 17 arranged in parallel in the left-right direction, and a feeding unit 19 and a hopper 20 are sequentially arranged upwardly on the support stands 18, and one end side support stand 18
Support rod 2 that penetrates and supports from to the support stand on the other end side
1, the float 17, the feeding part 19, and the hopper 20 are each integrally supported in an upright state, and the seeding bracket 1 is attached to the front central part of the support rod 21.
6 are installed in a row.

The float 17 is provided with notched grooves 22 on both sides of the rear part, and a groove creator 23 is provided in the front part of the notched grooves 22.
A cultivating soil plate 24 is provided at the rear, and a trencher 2 is installed at the rear.
3 and the soil plate 24, the lower end openings of the chute pipes 25 suspended from the feeding part 19 are opened.

In addition, a marker support rod 26 that is slidable in the left and right direction is supported horizontally through the sowing bracket 16, and left and right bending arms 27 and 27' are vertically installed at both ends of the marker support rod 26, respectively. death,
Left and right line markers 28 and 28' are connected to the tips of the left and right arms 27 and 27'.

When the sowing unit 3 is held at the center without being offset in the left and right direction, the left and right bending arms 2
7, 27' in the extended state, the left and right line drawing markers 28,
28' are spaced apart laterally from the end of the sowing section 3 by half the width of the sowing section 3, respectively. Therefore, the mark line m formed in the field by either of the line-drawing markers 28, 28' while performing the seeding operation is the same as the center marker 7 when the submerged direct sowing machine A is turned back at the edge of the field and allowed to sow. It is designed to serve as a landmark.

The marker support rod 26 is configured to be able to slide separately from the seeding section 3 by the same distance as the offset distance in the offset direction when the seeding section 3 is offset from the left and right sides. The movement is performed via an interlocking mechanism 29, and an example of this interlocking mechanism 29 is as shown in FIG. A long hole 32 is provided at the rear end of the same lever 30.
A pin 33 protruding above the center of the marker support rod 26 is fitted into the elongated hole 32, and the base end of a linear lever 34 is pivotally supported at the center of the intermediate bracket 12, and the tip of the lever 34 is connected to a dogleg-shaped lever. The distance from the pivot 31 at the center of the dogleg-shaped lever 30 to the front end is approximately the same as the distance from the pivot 31 to the rear end, so that the sowing unit 3 can be moved from the center. When offset to the left and right, the marker support rod 26 is slid in the offset direction by the same distance as the offset distance, so the left and right line drawing markers 28, 28' are moved by the offset distance from their original positions. It moves twice the distance to the offset side.

As another example of the interlocking mechanism 29, as shown in FIG. The lever 36 is interlocked with the right parallel link arm 15 so that the offset distance of the seeding section 3 to the left and right sides can be sensed. In the figure, 37 is a control device, 38 is an output device, 39 is a servo motor, 40 is a pinion gear connected to the motor 39, 41 is a rack gear connected to the marker support rod 26;
1 is meshed with a pinion gear 40, and when the seeding section 3 is offset to the left and right sides, the sensing device 3
5 senses the offset direction and offset distance, drives the servo motor 39 via the control device 37 and output device 38, and interlocks the pinion gear 40 so that the marker support rod 26 is aligned in the offset direction of the seeding section 3 and It is designed to be able to slide separately from the seeding section 3 by the same distance as the offset distance.

In addition, 42 in the figure is a feeding roll in the feeding section 19;
3 is a roll shaft to which the rolls 42 are connected, and 44 is a flexible pipe that drives the roll shaft 43.

The embodiment of the present invention is configured as described above, and while driving the front and rear wheels 8 and 9 to travel through the field, the groove-maker 23 forms grooves on the field surface.
The seeds in the hopper 20 are discharged into the same groove from the lower end opening of the chute pipe 25 through the feeding section 19, and the seeding work is carried out by cultivating the soil with the soil plate 24. Work is done.

Such seeding work is performed while proceeding in a straight line from one end of the field to the other, and at the other end, the direction is changed and the seeding is performed while proceeding in the opposite direction from before the direction change. At this time, the rows are aligned so that the 8 rows of sowing before the direction change and the 8 rows of sowing after the direction change do not overlap or are extremely separated from each other. For example, when the sowing unit 3 is held in the center without being offset, when moving forward, it is necessary to extend either the left or right turning arm 27, 27' on the side that should change direction and move forward. , bring one of the left and right line drawing markers 28, 28' into contact with the field to draw a mark line m on the field surface, and after changing the direction, align the center marker 7 with the mark line m so that the rows can be aligned. It's getting old. (See Fig. 5A) Also, when the sowing section 3 is offset to the left and right sides, in the case of the one in Fig. 3, the dogleg-shaped lever 30 is moved from the pivot 31 as the sowing section 3 moves.
The rear end of the lever 30 moves in the offset direction by the same distance as the offset distance, and the marker support rod 26 also moves the same distance, so that the left and right line markers 2
The arrangement of 8 and 28' is to move twice the offset distance in the offset direction compared to the original position, and in such a state, the direction should be changed and the next direction should be changed when moving in the same manner as described above. If one of the left and right line drawing markers 28, 28' on the side is brought into contact with the field and a mark line m is drawn, row alignment is possible by moving the center marker 7 along the mark line m after changing the direction. It is something.
(See Fig. 5B) In the case of Fig. 4, the offset direction and distance of the seeding section 3 are sensed by the sensing device 35, and the pinion gear 40 is interlocked to move the marker support rod 26 in the offset direction by the same distance as the offset distance. This part slides and moves separately from the seeding part.

According to the present invention, a marker support rod that can be slid laterally in the sowing section is horizontally supported, and left and right line-drawing markers are connected to both ends of the support rod, respectively, and the sowing section is connected to the sowing section through an interlocking mechanism. At the time of left and right lateral offset, the marker support rod is configured to be able to slide separately from the sowing section by the same distance as the offset distance in the offset direction, so that at the time of offset, the left and right line drawing markers automatically move appropriately, The mark line drawn with the same marker serves as the aim of the center marker without any adjustment operation, making it possible to align the rows and making seeding work extremely easy.
