Is fixed to the planting transmission case (44), and even if the guide is deformed, the planting arm (25) is located away from the planting arm (25) and close to the seedling extraction plate (100). There is no interference with 25).

Although a guide may be attached to the seedling extraction plate (100), the position of the hose changes due to the adjustment of the amount of seedling extraction, and there is a possibility that the hose may also come off.

Next, a fertilizer to which the fertilizer hose as described above is attached will be described.

In FIGS. 2, 7, and 8, (59) and (30) denote a hopper and a fertilizer hose as in the prior art.

The roll case (32) is connected to the hopper (59), and a gear case (3) fixed to the top of the roll case (32) integrally with the case via a gear holder (36).
In (7), there is an internal gear (33) of the planetary gear device. A planetary gear (34) meshing with the internal gear (33) and a sun gear (35) meshing with the planetary gear (33) are provided in the gear case (37).

The planetary gear (34) is
Driven via the connecting plate (28).

(39) is a sun gear shaft which drives a discharge spring (27) attached thereto to increase the speed. The feeding roll (68), which will be described later, is driven by the hollow outer shaft (38) but is not accelerated.

The output from the input shaft (40) shown in FIG. 3 is transmitted through the one-way clutches (41) and (41) to the hollow outer shaft (38).
a) is driven, and a clutch (77) which will be described further below
, The hollow outer shaft (38) is driven, and the sun gear shaft (39) is intermittently driven in one direction by the sun gear (35) from the planetary gear (34) driven by the hollow outer shaft (38).

At the center of the inner hollow outer shaft (38) is a sun gear shaft (39), and the inner and outer hollow outer shafts (38) (38a) are supported by a support cylinder (43) extending from the gear case (42) of the roll case (32). )
Supported by.

The one-way clutches (41) and (41) described above are provided between the support cylinder (43) and the outer hollow outer shaft (38a).

Discharge spring (27) in fertilizer hose on sun gear shaft (39)
Is attached, and the input shaft (40) is a rotary case (4
5) through a link mechanism. Specifically, as shown in FIG. 1, the safety clutch (46) is connected to the chain and sprocket (46a) from the planting transmission case (44).
The drive shaft (46) of the rotary case (45) is driven via the b), the sprocket (49) is driven via the sprocket (47) and the chain (48), and the eccentric link (50) The eccentric pin (52) is driven by the rotation of the rotary case (45) via 51).

A connecting rod (53) is attached to the eccentric pin (52), and the upper end of the connecting rod (53) is pivotally supported (56) on a long arm (54) as shown in FIGS.

The U-arm (60) of the long arm (54) pivotally supported (61) is pivotally supported (62) on the crank (63), and the input shaft (40) is driven by the crank (63).

The proximal end of the long link (54) is pivoted (5
7) The short arm (55) is pivoted (5) to the frame (64).
8) Has been.

Further, the connecting pivot point (57) between the short arm (55) and the long arm (54) can be moved up and down by an adjustment handle (65) shown in FIGS. 11 and 12, whereby the connecting rod (53) swings. Adjust the moving angle. This condition is shown in FIGS.

The adjustment handle is a pivotable shaft (67) with respect to the frame.
And the tip is attached to the arm (55a) that moves integrally with the short arm (55), and the attachment shaft (55b) is provided on the guide plate (64a) by screwing in and out of the adjustment handle (65). It slides in the slit groove (66).

Therefore, when the rotary is driven after adjusting the position of the pivot shaft (57) with the adjusting handle (65), the rotary drive shaft (46) is driven, and the sprocket is driven through the sprocket (47) and the chain (48). The eccentric pin (5) is driven from its shaft (50) via the eccentric link (51).
2) is driven.

The connecting rod (53) is driven by the eccentric pin (52), the U-arm (60) is driven via a link mechanism composed of a long arm (54) and a short arm (55), and an input is made by a crank (63). Turn the shaft (40) forward and backward.

Thus, as described above, the input shaft (40) is connected to the outer hollow outer shaft (38) via the one-way clutch (41) (41).
a) is intermittently driven in one direction.

The hollow outer shaft (38) drives the pay-out roll as described later, and the one-way clutches (41) and (41) as described above are mounted on the outer outer shaft (38) which is the pay-out roll drive shaft. Since it is provided on the hollow outer shaft (38a), play and backlash in the power transmission system are minimized, and the feeding accuracy is improved.

In addition, since the power of the rotary drive shaft (46) in the planting transmission case (44) is transmitted to the shaft (50) by the chain (48), the safety clutch of the fertilizer application drive unit is connected to the planting arm (25).
The safety clutch can also be used, resulting in a lightweight and compact configuration.

In addition, since the power of the rotary drive shaft (46) in the planting transmission case (44) is transmitted to the shaft (50) by the chain (48), foreign matter or the like bites into the fertilizer drive unit, and the safety clutch is activated. At this time, the impact force is gradually transmitted by the chain interference, and the operating torque of the safety clutch is dynamically stabilized.

That is, there is more play in the chain drive than in the gear drive, and the chain is slack because the chain is not taut, and there is a play corresponding to the slack, thus providing a cushioning effect.

Next, the feeding roll driven by the above-described drive system will be described. As shown in FIG. 13, the feeding roll (68) includes an upper roll (68a) having a semicircular hole (69) and a sector-shaped hole (70). ) With the lower roll (68b)
There is a roll (68c) with a middle.

Then, the middle roll (68c) is rotated by the inner hollow outer shaft (38).

In FIG. 3, a rubber elastic body (73a) is attached to a rubber elastic body (73) on an eccentric shaft (73) of a knob (72), and by turning the knob (72), the upper roll (68a) and the middle roll are turned. By adjusting how much the rubber elastic body enters the gap between the roll (68c) and the upper surface of the fertilizer filled in the middle roll (68c), the top surface of the fertilizer is trimmed with rubber, and the amount of fertilizer applied is minutely adjusted.

As described above, the sun gear shaft (39), the hollow outer shaft (38a) having the clutch portion, and the hollow outer shaft (38) constitute three shafts. (68a) and a spring (74).

As a result, the roll (68) is rotated while the fertilizer enters from above from the direction where it is constantly pressed by the spring (74), and this is added to the weight of the fertilizer and the roll is pressed. Gaps are less likely to occur, which is effective in preventing the fertilizer from being caught between the rolls.

Further, the driving of the roll becomes smooth, and the durability of the roll is also improved.

In addition, a handle (75) suspended on the roll case (32) in FIGS. 2 and 5 is a handle for operating the unit clutch, and is provided from the outer hollow outer shaft (38a) through the outer hollow outer shaft (38). This turns on and off the transmission of power to the planetary gear (34), and stops the rotation of the feeding roll (68).

The pin (76) operated by the handle (75) is inserted between the upper part of the clutch (77) and the intermediate flange (78) (79), and the clutch (7) is rotated by rotating the handle (75).
7) Move up and down.

A plurality of pins (80) protrude from the intermediate flange (79) of the clutch (77), and when the pins (80) descend, a hollow outer shaft (38) is formed.
It engages with the slot (82) of the collar ring (81) fixed to a), transmits power from the hollow outer shaft (38a) to the hollow outer shaft (38), and then through the connecting plate (28). The light is transmitted to the planetary gear (34), and the sun gear shaft (39) is rotated.

Also, by rotating the handle (75) in the opposite direction to the previous operation to oppose the spring (84) and raise the clutch (77), the pin (80) is turned into the slot ( 82), power is not transmitted from the hollow outer shaft (38a) to the hollow outer shaft (38), and thus is not transmitted to the planetary gear (34).

 Therefore, the sun gear shaft (39) does not rotate.

2, (91) is a communication hole between the hopper (59) and the roll case (32), (92) is a fertilizer discharge hole,
(93) shows the respective rubber caps.

As described above, the rotation of the handle (75) causes the clutch (77) to move up and down, thereby stopping the rotation of the feeding roll (68). This is a so-called stop clutch, which is shown in FIG. The head of the roll case (32) is covered with a cover (103) as described above, and the cover (103) is provided with a notch hole (104) large enough to insert the handle (75). The cover is configured to have a shape in which the cover (103) can be attached and detached while the power continuation clutch switching lever is on.

The cover (103) is detachable from the head of the roll case (32) with bands (105) and (106), and the direction of the handle (75) for turning off the handle (75) has a cutout hole (104). The handle (75) prevents the cover (103) from coming off because it looks like a cross.

In any case, the handle (75) can be operated with the locking clutch attached with the cover (103).

In addition, most of the handle state is in the on state, so it is detachable in the "on" state, which reduces the notch and visually confirms the "in" position of the handle It is possible.

Furthermore, the handle (75) is not wetted by the cover (103). As shown in the figure, the cover can be removed for each strip, or can be formed to cover several strips at a time.
