DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a simultaneous scratching and transplanting machine capable of simultaneously performing a scraping operation, a planting operation, and a fertilizing operation.

[0002]

2. Description of the Related Art In general, planting of rice seedlings takes several days after a roughing step is carried out by a roughing machine in a state where water is sufficiently filled in a roughened field and water is retained, and then the roughened surface is stabilized. Later, rice transplanting of seedlings is performed by a rice transplanter. However, the rice transplanting operation is a complicated operation such as performing a scratching step and requiring water to fall in a field before planting.

[0003] In recent years, the present applicant has developed a technique for simultaneous transplantation of seeds in the surface layer, which enables labor saving of these complicated works and promotes seedling survival while promoting good growth. Japanese Patent Laid-Open Publication No. 6-7 / 1994 has proposed a substitute simultaneous planting machine capable of simultaneously performing planting work. In this simultaneous scraping planting machine, a scraping rotor (that is, a harrow member) which is rotationally driven via a support member such as a bracket and a stay is integrated with a front portion of a planting device mounted behind a traveling body. In addition to this, the width of this scraping rotor is configured to have a wide shape that protrudes to the middle of the strip on both sides of the planting width of multiple rows, while crushing the plowed surface before planting seedlings In the meantime, it is in a scratching state.

[0004]

However, in the conventional simultaneous scraping planting machine, the rough soil on the field in the field is crushed by the scraping rotor to enable planting. When applying fertilizer, it is necessary to make the ground insertion depth of the fertilizing nozzle deeper than the crushed portion of the substitute rotor in view of the relationship with the planting depth.

Since the fertilizing nozzle is deeper than the portion crushed by the scraping rotor, the fertilizing nozzle must cut the rough soil on the rice field by itself, and therefore, a large resistance acts on the fertilizing nozzle. . On the other hand, since the fertilizer nozzle is provided directly on the float that supports the planting device, the fertilizer nozzle is held up slightly by the resistance of cutting the rice field, and the height of the float relative to the rice field changes. There is a problem that the fertilization depth is not stable because the approach depth changes according to the water depth.

[0006] In particular, the fertilizer application depth is determined in two steps up and down, and further in three steps so as to be able to meet various conditions. In this case, fertilizer is injected or injected into a deep position. Since the fertilizing nozzle to be guided receives considerable resistance, it is not possible to apply fertilizer to an accurate depth. In some cases, disturbance of the posture of the float or the like may cause trouble in planting.

It is an object of the present invention to provide a simultaneous substitute planting machine which can efficiently perform fertilization on a rice field to a predetermined depth and does not affect the planting operation. It is.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the substitute simultaneous transplanting machine according to the present invention comprises a traveling machine A.

Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral A in FIG. 1 denotes a traveling body having a front wheel 1 and a rear wheel 2. The traveling body A is provided with a steering wheel 3 and a driver's seat 4 at an upper portion, and a top link 5 which is driven up and down by a hydraulic cylinder mechanism or the like at the rear. The hitch link 7 is connected to the rear end of the lower link 6, 6, etc., and the planting device B is inserted 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. Is installed to freely roll left and right.

The planting apparatus B is provided with a planting table 11 and a planting mechanism (planting claw) 12 on a planting machine frame 10 integrally supporting the rolling shaft 9. 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, 15 are provided on both sides of the planting machine frame 10 so as to protrude forward, and the brackets 15, 15 are provided with stays 1 via support shafts 16, 16.
The right and left stays 17 and 17 are provided with a scraping rotor 18 at the distal ends thereof.

The substitute rotor 18 of this embodiment is formed of a metal cylindrical body, and a lug-shaped ridge 18a bent in a zigzag shape as shown in FIGS. A plurality of cutters 20 are provided so as to protrude at intervals at which the fertilizing nozzle 26 passes in the axial direction. The cutter 20 has an important function in the present invention. The cutter 20 cuts or cuts in a groove shape in advance so that the fertilizer nozzle 26 does not give a large resistance when passing through the rice field. As shown in FIG. 6 (a), a number of relatively large isosceles triangular groove cutting teeth 20b are continuously provided over the entire outer periphery of the disk 20a. As shown in FIG. 2), the width between the outer circumferences of the leading ends of the groove cutting teeth 20b bent to the left and right is made substantially equal to the width of the fertilizing nozzle 26, while being alternately bent right and left from the base to form a set. is there.

By rotating the scraping rotor 18 in contact with the roughened plowing surface, the surface layer of the ground is crushed, and the ground is leveled evenly to obtain a scraping state. The soil is crushed in a narrow groove shape to the depth where the fertilizing nozzle 26 passes. In this embodiment, the fertilizer nozzle 26 accommodates a paste-like fertilizer in a fertilizer tank 27 installed in front of the machine body as shown in FIG.
Although the nozzle for the paste-like fertilizer that discharges the fertilizer into the ground by the fertilizer application pump 28 is shown, a separate mechanism may be configured to feed and discharge the granular fertilizer.

The substitute rotor 18 is shown in FIG.
As shown in FIG. 2, the input shaft 24 of the gear case 23 is driven via the transmission shaft 21 receiving power from the traveling machine body A and the telescopic free joint shaft 22 as shown in FIG. It is designed to be driven. Reference numeral 29 denotes an operation lever for raising and lowering the planting portion B disposed beside the driver's seat 4, and is configured to be switchable to four positions U, N, D1, and D2 as shown in FIG.

First, (a) when the operating lever 29 is set to the U position (elevated position), the planting device B ascends with its power cut off. (B) Next, when the operating lever 29 is set to the N position, the planting apparatus B is prevented from descending in a state where its power is cut off, and is held neutral. (C) And the operating lever 29
Is set to the D1 position (down position), the planting apparatus B descends, the sliding body 13 touches the rice field surface, and the vertical position of the sliding body 13 is detected.

At this time, the power of the planting apparatus B is cut off, and when the operating lever 29 is further moved to the position D2, the power of the planting apparatus B is kept in the automatic state with the elevation control of the planting apparatus B. And the planting operation can be started. When the planting operation is performed by the planting machine of the present invention, after the rice field is appropriately roughened, the flooded soil is softened beforehand. Then, a field is prepared by dropping water around the day before the scheduled planting work date and draining water from the surface of the rice field as much as possible.

After that, the substitute planting machine of the present invention is introduced into the field, and the fertilizing nozzle 26 is passed through this portion while driving the substitute rotor while driving the substitute work and cutting the groove with the cutter 20. When the planting work is started, water is sufficiently absorbed and the soil surface in a softened state is leveled by the action of the outer circumferential surface of the rotatable rotor 18 and the ridge 18a. 13 mounted on the planting device B
And the planting action of the planting mechanism 12 is smoothed.

The fertilizer can be fertilized to a predetermined depth at the same time as planting by spraying paste-like fertilizer from the fertilizing nozzle 26. The cutter 20 is provided integrally with the substitute rotor 18, and a groove having a constant depth can be formed, thereby contributing to stabilization of the fertilization depth. In addition, the fertilizing nozzle 26 can pass through the groove with low resistance.
