Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simultaneous scraping and planting machine for simultaneously carrying out scraping work and planting work.

[0002]

2. Description of the Related Art Generally, planting of seedlings for rice action is carried out for several days after the scratching process with a scratching machine is performed after a sufficient amount of water has been filled in a roughened field to retain water. Later, rice planting work for seedlings is being carried out by a rice transplanter. However, the above-mentioned rice planting work is a complicated work in which the drainage of the field is required before the planting, in addition to the plucking process. Therefore, in recent years, the present applicant has developed a surface-layer scraping simultaneous transplanting technology that can satisfactorily cultivate these seedlings while promoting labor-saving of these complicated operations, and carry out the scraping work and the planting work. There has been proposed a simultaneous scraping and planting machine that can be operated at the same time (Japanese Patent Laid-Open No. 6-7).

In this substitute scraping planter, a substitute rotor R (halo member) which is rotatably driven via a supporting member such as a bracket and a stay is integrated with the front part of the planting device mounted to the rear of the traveling machine body. 8 as shown in FIG. 8, the width of the scraping rotor R is configured to be a wide shape protruding to the middle of the row L on both sides of the planting width for a plurality of rows. Prior to the planting, the plowing surface is finely ground and leveled so as to be in a scratched state.

[0004]

However, in the conventional simultaneous plucking simultaneous planting machine, since the plucking rotor protrudes largely on both sides of the planting width, it is adjacent to the seedling row on which the previous planting has been performed. When the side edges of the scraping rotor are moved close to each other and run by scraping, there is a drawback that the scratched mud touches the seedling or the scraped mud acts to push down the seedling. Therefore, it is necessary to slow down the running speed of the aircraft, which causes a problem of reduced efficiency.In addition, when the scraper rotor is moved away from the seedling to carry out the scraping, the simultaneous scraping planting work is performed. There is a fear that the distance between the adjacent width and the width of the width will be wider than the appropriate distance, and there will be leftovers left behind, which will cause weeds to grow.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the simultaneous scratch transplanter according to the present invention is a traveling machine body 1.
To the planting device B and the planting width H in front of the planting device B.
(FIG. 6) In a planting machine equipped with a halo member 18 for scratching the entire body, the scratching posture in which the halo member 18 is displaced to the left and protrudes into the left striation of the planting width H It is characterized in that it is configured so that it can be moved by switching to a rightwardly staggered posture in which it is biased to the right and protrudes into the right striation.

Further, the switching movement of the halo member 18 is interlocked with the operating lever 29 (FIG. 2) with lifting and lowering plant, and when it is moved to the ascending position U (FIG. 5), it is returned to the neutral position, and the lifting and lowering plant is also moved. When the operation lever 29 is operated to the lowered position D1, the marker 50 is interlocked with the left / right protrusion switching. When the marker 50 is protruded to the left, the halo member 18 is moved to the left and the marker 50 is moved to the right. It is characterized in that the halo member 18 is moved to the right when it is projected.

[0007]

[Operation] The halo member 18 can be moved to the left or right according to the traveling direction of the aircraft to project to the unplanted seedling side, so that the seedlings that have already been planted may be damaged or pushed down by the mud when scraping the seeds. It is possible to satisfactorily perform the simultaneous plucking operation without causing scratches and without leaving a residual scratch left between adjacent seedling rows in the previous step.

Further, by operating the raising / lowering planting operation lever 29 to the raised position position U side, the halo member 18 is returned to the neutral position in conjunction with the raising of the planting device B, and is moved to the lowered position position D1. When the marker 50 is operated so as to project right and left at the operation position, the halo member 18 can be switched and moved in the projecting direction of the marker 50 based on this operation, and the simultaneous plucking operation can be performed easily. .

[Example] Reference numeral A is a traveling machine body having a front wheel 1 and a rear wheel 2, a steering handlebar 3 and a driver's seat 4 are provided on an upper portion of the traveling machine body A, and a top which is driven up and down by a hydraulic cylinder mechanism or the like is provided at the rear. A hitch link 7 is connected to the rear ends of the link 5 and the lower links 6, 6 and the like, and is planted through a rolling shaft 9 (FIG. 2) in the front-rear direction which is inserted and supported by a rolling metal 8 below the hitch link 7. Device B is mounted so that it can be rolled left and right.

In the planting apparatus B, a planting machine frame 10 that integrally supports the rolling shaft 9 is equipped with a seedling stand 11 and a planting mechanism (planting claw) 12, and this planting machine is used. A sliding body 13 is supported below the frame 10 so as to be vertically movable around a support shaft 14 (FIG. 3). Brackets 15 and 15 projecting forward are provided on both sides of the planting machine frame 10, and the stays 1 are attached to the brackets 15 and 15 via support shafts 16 and 16.
7, 17 are attached, and the scraping shaft 19 of the scraping rotor 18 is rotatable at the tip of the left and right stays 17, 17 by the configuration described later, and in the width direction of the traveling machine body A (left and right).
It is supported so that it can slide.

The scraping rotor 18 of this embodiment is formed of a metal cylindrical body, and a lug-shaped ridge 20 ... Bent in a zigzag shape is welded to the outer peripheral surface thereof as shown in FIGS. A large number of protrusions are provided with a gap in the axial direction, and the surface layer of the ground is finely ground by rotating it in contact with the roughened plowing surface, and the ground is leveled evenly and scratched. I am trying to become.

In this embodiment, the fertilizer application nozzle 40
Shows a nozzle for paste-like fertilizer that stores paste-like fertilizer in a fertilizer tank 41 (Fig. 1) installed in front of the fuselage and discharges the fertilizer into the ground by the fertilizer application pump 42. The granular fertilizer may be fed and discharged.
Then, the substitute scraper rotor 18 is driven via a transmission shaft 21, which receives power from the traveling machine body A, a freely extendable joint shaft 22, an input shaft 24 (FIG. 2) of the gear case 23, and a substitute scraper shaft 19. It is like this.

A base 25 (FIG. 3) is installed between the gear case 23 and the universal joint shaft 22.
In addition, an ultrasonic sensor 26 for detecting the ground height of the scratch rotor 18 is installed. As the ultrasonic sensor 26, it is preferable to use a non-contact type ground height sensor that detects the paddy field immediately before scratching. Further, an arm 27 is integrally attached to the front end of the rolling shaft 9 (FIG. 2) toward the front, and an electric cylinder 28 (having a built-in stroke sensor between the arm 27 and the scratch shaft 19 ( 1) is mounted, and the scraping rotor 18 is vertically moved by the expansion and contraction operation of the electric cylinder 28.

A double-acting reciprocating cylinder 46 (FIG. 2) is fixed to the gear case 23. The reciprocating cylinder 46 is supported between the stays 17 and 17 and also serves as a piston rod and a supporting rod 45. The switching lever 47 is operated left and right within the lever guide 47a to operate the reciprocating cylinder 46 left and right via a hydraulic device, and the scraping rotor 18 is supported by the support rod 45. In this state, it is configured so that it can be displaced laterally by a predetermined amount.

That is, as shown in FIG. 6, the scraping rotor 18 can scrape the entire front surface of the planting width H of 6 rows of seedlings, and the scraping rotor 18 is biased to the right. In the state of being moved, its left end is projected by a length L1 which is close to or coincides with the left end of the sliding body (sledding body) 13 located in front of the seedlings to be planted, and the right end is next to this rightmost seedling and next. Length L that is more than half the length L between the shoots and the shoots to be planted in the process
It is formed so as to protrude as much as 2 and to satisfy the relation of inter-row L≤L1 + L2 (however, L1 <L2) so as not to generate an unsprayed portion as much as possible in the adjacent inter-row L3 within the adjacent planting width H. ing.

[0016] Then, the scraping rotor 18 which is projected for a long time
By moving the machine body A in the direction of the arrow so that the length L2 side (deviation to the right) becomes the unplanted side, planting work is performed from the already planted seedling row side to the scraping rotor 18 side. Left edge (L1)
Can be separated as much as possible within the range of the space L,
The influence of mud during scraping is reduced, and planting work is performed simultaneously with good scraping while preventing pushing down of seedlings already planted.

In addition, the aircraft A is turned around at the headland and the aircraft A is turned around.
When the planting work is performed from the right side with the left side of the left as unplanted land, the switching lever 47 (FIG. 2) can be operated to the left side to cause the substitute scraper rotor 18 to be displaced to the left side by L2 so as to project. Therefore, good work can be performed in the same manner as described above. Reference numeral 29 denotes an operation lever (hereinafter referred to as an operation lever) with a lifting plant disposed beside the driver's seat 4, which can be switched to four positions U, N, D1 and D2 as shown in FIGS. 1 and 5. To be done.

First, when the operating lever 29 is set to the U position (elevating position), the planting device B is raised with its power cut off. Next, when the operation lever 29 is set to the N position, the planting apparatus B is prevented from descending and its neutral state is maintained in a state where its power is cut off. Then, when the operation lever 29 is set to the D1 position (down position), the planting device B descends, the sliding body 13 contacts the paddy field, and the vertical position of the sliding body 13 is detected to control the planting device B up and down automatically. To At this time, the power of the planting apparatus B is cut off, and when the operation lever 29 is moved to the D2 position, the power of the planting apparatus B is transmitted while the up-and-down control of the planting apparatus B is kept in the automatic state. Planting work can be started.

The operation piece 31 of the switch 30 (FIG. 5) is positioned so as to face the operation path of D1 and D2 of the operation lever 29. When the operation lever 29 is shifted to the D1 and D2 positions, the switch 30 is turned on. Then, the electric cylinder 28 (FIG. 1) that moves up and down the scraping rotor 18 expands and contracts according to a command from the microcomputer circuit based on the detection result of the ground height sensor 26, so that the grounding height of the scraping rotor 28 becomes constant. Control automatically.

When the operating lever 29 is shifted to the N and U positions, the switch 30 is turned off, and the scraping rotor 18 detects the neutral position of the ascending / descending range by the ground height sensor 26 and holds it at that position. Then, the independent raising and lowering is stopped and the planting apparatus B is raised and lowered. Further, as shown in FIGS. 5 and 9, the substitute scraper rotor 18 is interlocked with a raising / lowering planting operation lever 29 together with a marker 50 (FIG. 2) having a known structure for drawing the planting position in the next step to the ground. It is possible to prevent an erroneous operation and to easily perform the operation by using the microcomputer circuit to enable the operation.

That is, when the raising / lowering planting operation lever 29 is operated to the raised position position U of the lever guide 29a, the planting device B is raised and, in conjunction with this raising operation, is pivotally supported so that it can be undulated on both sides of the machine body. The marker 50 is raised, and the harrow member 18 is caused to project from one side to return to the neutral position located on the center side of the machine body as shown by the solid line in FIG. Next, operation lever 29 with lifting planting
The planting device B can be lowered by operating the lever to the lowered position position D1, and after switching from the D1 position to the D2 position, the left and right grooves of the lever guide 29a are selectively tilted to the right side. Or the marker 5 on the left side
0 is projected and lowered to a drawing posture, and the marker switch right 51 or the marker switch left 52 is turned on in conjunction with the protrusion and lowering of the markers 50, 50 to move the substitute rotor 18 toward the same direction side. It is designed to move in a protruding manner.

In this case, although not shown, the movement of the scraping rotor 18 to the left and right and the movement to the neutral position are surely performed by microcomputer control by attaching a known stroke sensor to the reciprocating cylinder 46. You can
With the above-described configuration, in the simultaneous scratching planting work performed by reciprocating the machine body A, the operation of always setting the marker 50 and the scratching rotor 18 to the unplanted side in association with the raising / lowering operation of the planting device B is incorrect. It can be done easily without.

When carrying out planting work with the planting machine of the present invention, the rice field is appropriately roughened and then flooded to loosen the roughened soil. Then, prepare a field by dropping water around the day before the planned planting work and draining the water from the surface of the rice field as much as possible. Then, when the planting work was started while the planting machine of the present invention was introduced into the field and the planting rotor 18 was driven, the soil surface in a puffed and soft state was sufficiently absorbed by water. The outer peripheral surface and the ridges 20 smooth the soil, and the water appropriately exudes to the rice field and the sliding action of the sliding body 13 and the planting mechanism 12 mounted on the subsequent planting device B are smoothed. To

The surrogate scraper rotor 18 is controlled up and down by an electric cylinder 28 (FIG. 1) independently of the lifting control of the planting device B. That is, the ground-height sensor 26 detects the ground-height of the scraper rotor 18, and the electric cylinder 28 does not operate within the appropriate height range. For example, when the depth of scratches becomes shallower than the set height, the distance between the rice field and the ground height sensor 26 becomes longer, and based on the detection result, the electric cylinder 2 is instructed via the microcomputer circuit.
8 is extended, and the scraping rotor 18 is lowered to control the height to an appropriate height.

On the contrary, when the depth of the scratch is deeper than the set height, the distance between the rice field and the ground height sensor 26 becomes large, and the electric cylinder 28 is contracted by a command via the microcomputer circuit based on the detection result. The scraping rotor 18 is lifted and controlled to a proper height. In this way, the raising and lowering rotor 18 is automatically controlled so as to always have an appropriate height with respect to the rice field.

The raising and lowering of the planting device B is carried out in the same manner as in the conventional case by the sliding body 1.
Although the top link 6 and the lower links 7 and 7 are automatically moved up and down based on the height position of the planting machine frame 3 of the planting machine frame 10 as described above, as described above, the depth of the scraping rotor 18 is scratched. Since it can be maintained within the setting range,
The subsequent automatic raising / lowering control of the planting apparatus B can be smoothly performed on the basis of the sliding body 13.

When the simultaneous scraping planting work is performed in this manner, the scraping rotor 18 is not projected to the both sides in front of the planting width H unlike the conventional one, and only one side is not projected. Since it is provided so that it can be moved to the left and right in accordance with the direction of planting so as to perform the scraping work by making it largely protrude into the planting strip, the scraping rotor 18 is separated from the seedlings already planted. With no adverse effects such as pushing down the seedlings due to mud that is moved during contact or scratching, without leaving scratches between adjacent rows between adjacent planting widths,
It is possible to carry out an excellent simultaneous scraping operation by performing the scraping operation while properly maintaining the spacing between the predetermined widths.

FIG. 7 shows another embodiment, in which a substitute rotor 18 having the same structure as that of the above embodiment is mounted on the front part of the traveling machine body A, and an ascending / descending link mechanism 31 which is moved up and down by an electric cylinder 28. In addition, a scraping rotor 18 is mounted so as to be capable of rolling. The height above ground is determined by detecting the vertical movement of the front end of the sled body 32 sliding on the rice field with the potentiometer 33.

In this way, the scraping rotor 18 is mounted on the traveling body A.
When it is mounted on the front part of No. 3, there is more space than when it is mounted between the rear wheel 2 and the planting device B, and there is an advantage that a skiding device suitable for the field conditions can be appropriately selected and equipped. .

[0030]

According to the first aspect of the present invention, the work for scraping and the planting work can be simultaneously performed to save the labor, and the halo member 18 can be switched to the left and right in front of the planting device B. It is possible to carry out a good simultaneous planting work with a substitute while preventing the occurrence of pushing down the leftover soil and the planted seedlings while making the device smaller and lighter.

Further, the operation can be performed while easily maintaining the space between adjacent planting widths, which is not likely to widen the space between adjacent plants. According to the second aspect, the marker 50 and the halo member 18 can be switched in the same direction in conjunction with the raising and lowering of the planting device B when the traveling direction of the machine body A is changed, so that an error-free operation can be easily performed. Therefore, it is possible to easily perform an excellent simultaneous plucking operation.
