JPH065B2 - Fertilizer interlocking device of seedling planting machine - Google Patents

Description

TECHNICAL FIELD The present invention relates to a fertilizer interlocking device for a seedling planting machine.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a fertilizer application device of a seedling planter that feeds out the fertilizer in the hopper and fertilizes it into the soil through a transportation route, a fertilizer feeding device and a seedling planting device are used. When simultaneously operating the respective operating mechanisms, since the fertilizer transport path is long, fertilizer is applied after the seedlings have been inoculated and fertilization is not applied to the seedlings in the initial stage of inoculation. Therefore, at the beginning of planting, a fertilizer-free area is created.

Means for Solving the Problem The present invention, in order to solve the above problems, of the operation wire (28) for turning on and off the feeding clutch (3) of the feeding device (2) for feeding the fertilizer of the hopper (1). An arm (25) connecting the ends,
An arm (26) connecting the ends of an operation wire (29) for opening and closing a planting clutch (6) of a planting device (5) for planting seedlings supplied from a seedling tank (4), Operation lever (20) that activates cams (23) and (24) that swing and drive both arms (25) and (26) respectively
Is provided, and the arm (25) (26) and the cam (2) are engaged so that the feeding clutch (3) is engaged prior to the engagement of the planting clutch (6).
3) It is a fertilizer interlocking device of a seedling planting machine, which is provided with an operating mechanism (7) linked to (24).

Advantageous Effects of the Invention The present invention is designed so that the arm (25) (26) and the cam (23) (2) are engaged so that the delivery clutch (3) is engaged prior to the engagement of the planting clutch (6).
Since the operating mechanism (7) linked with (4) is provided, it is possible to perform the on / off operation of the planting clutch (6) and the on / off operation of the feeding clutch (3) with a light operating force and accurately. By doing so, the fertilizer-free area at the start of planting work can be eliminated and accurate fertilizer planting work can be performed.

Embodiment In the illustrated example, (8) is a traveling vehicle body, which has a pair of left and right front wheels (9) and rear wheels (10), and is driven by the front wheels (9) and rear wheels (10). At the same time, a prime mover room (11) is provided on the front side of the traveling vehicle body (8) and a cockpit (12) is provided on the rear side. A link device (13) that moves up and down by a hydraulic mechanism is pivotally attached to the rear end of the traveling vehicle body (8), and a seedling tank (4) and a planting device (5) are provided at the rear end of the link device (13). The provided seedling planting device (14) is connected.

A blower fan (15) is provided in the engine room (11), and a hopper (1) is provided on the lateral side. A feeding device (2) is connected to the lower part of the hopper (1), and the feeding device (2) has a feeding clutch (3).
The transmission can be turned on and off via.

The outlet of the blower fan (15) communicates with the air reservoir (16), and a plurality of pipes (17) are branched on the outlet side of the air reservoir (16) to discharge the lower end of the feeding device (2). Communicate with each of these pipes
(17) is further extended rearward, and discharge ports (18) are provided near the planting device (5).

The planting device (5) is provided with a planting clutch (6), and transmission to the planting device (5) can be turned on and off by the planting clutch (6).

The operation mechanism (7) is provided with an operation lever (20) on a control platform (19) on the side of the cockpit (12), and by operating the lever, the feeding clutch (3) and the planting clutch (6) are related. It is configured to move.

A rotating shaft (21) is fixed to the lower end of the operating lever (20), and a swing shaft (22) is arranged in parallel on the upper side of the rotating shaft (21).

On both sides of the operation lever (20) of the rotating shaft (21), a plate-shaped cam (2
3) and cam (24) are fixed.

One ends of arms (25) and (26) are fixed to both sides of the swing shaft (22), and a slider (27) is provided at the center of each of the arms (25) and (26). (23) Abut on the outer peripheral surface of (24).

The tip of the arm (25) is connected to the feeding clutch (3) by an operation wire (28), and the tip of the arm (26) is connected to the planting clutch (6) by an operation wire (29). The springs urge the clutches (3) and (6) in the on and off directions.

The cams (23) and (24) are two-stage cams, and when the operation lever (20) is entered, a slider (27) abuts on the outer peripheral surface of the cams (23) and (24) and the arms (25) ( Set the feeding clutch (3) side arm (25) of
Swing shaft (22) ahead of arm (26) on planting clutch (6) side
It is configured to swing around.

Further, an oil damper (30) is provided at the upper end of the tip of the arm (26) on the side of the clutch with plant (6) to brake the rotation of the arm (26).

When fertilizer is supplied to the hopper (1), seedlings are placed on the seedling tank (4), power is transmitted to each part to move the traveling vehicle body (8) forward, and the operation lever (20) is turned on and operated to turn the rotary shaft (21 ), The sliders (27) of the arms (25) and (26) come into contact with the outer peripheral surfaces of the cams (23) and (24), and these arms (25) and (26) move around the swing shaft (22). The rotation is started (Fig. 1).

The slider (27) of the arm (25) rotates the arm (25) while contacting the outer peripheral surface of the cam (23) to engage the operation clutch (3) via the operation wire (28).

The slider (27) of the arm (26) contacts the outer peripheral surface of the cam (24) and rotates, but the arm (26) does not rotate (FIG. 2).

Therefore, only the feeding clutch (3) enters and is transmitted to the feeding device (2), the fertilizer in the hopper (1) is fed out, conveyed in the pipe (17), and sprayed on the soil surface.

When the operation lever (20) is fully inserted, the arm (26) slide
The arm (26) rotates while being guided by the outer peripheral surface of the cam (24) while the arm (26) rotates and is braked by the oil damper (30). Enter 6) (Fig. 3).

Therefore, the seedlings in the seedling tank (4) are transmitted by being transmitted to the planting device (5).

When the operation lever (20) is turned off, the planting clutch (6) is turned ahead of the feeding clutch (3), but no fertilizer-free zone for planting seedlings occurs.
