DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a potato planter in which seeds to be conveyed by a conveying member of a conveying belt flow down on a planting gutter and are discharged and planted at the downstream end.

[0002]

Conventionally, a potato planter as described above has been used to plant a round pot or a cut potato (cut potato), but a thin potato potato (cut potato) is used. In this case, the thickness differs depending on the preference of the supply source or the variety, the seed potato flows downward from the gap between the conveying member and the planting gutter, and the planting pitch changes. In the case of a conveyor belt, the gap between the conveyor member and the planting gutter is not constant between the slack portion between the belt pulleys and the tension portion near the pulley, and the gap in the tension portion is larger than the belt slack portion. Therefore, there is a problem that the seed potatoes pass through at this portion and the planting pitch changes.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a potato planter in which a seed potato conveyed by a conveying member on the surface of an endless conveying belt is caused to flow down a planting gutter and is planted. Spacers for reducing the spacing between the planting gutters to a predetermined value or less are appropriately provided at the enlarged portion of the spacing between the planting gutters. If it is larger, the spacing between the transporting member and the planting gutter is adjusted by the spacer to maintain the planting pitch properly and stably maintain the planting accuracy.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory side view of a seed potato transporter, FIG.
FIG. 3 is a side view of the whole, and FIG. 3 is a plan view thereof. A traveling drive case (3) is integrally connected to a rear end of a body frame (2) on which an engine (1) is mounted, and a lower portion of the drive case (3) is provided. The left and right running wheels (5) and (5) are pivotally supported on both sides via an axle (4), and the base end of a steering handle (7) is provided above a drive case (3) via a handle base (6). Is mounted so that it can be moved back and forth, and a single-row potato planter (10) is mounted behind the drive case (3) via a hitch (8) and a mounting frame (9).

The potato planting machine (10) comprises a potato planting section (14) having a potato scooping hopper (11), a potato transport belt (12), a potato planting gutter (13) and the like, and a potato plant (15). ), A groove cutter (16) for forming a groove for placing the seeds at regular intervals, a soil covering plate (17) for covering the seed potatoes (15) in the groove, and an inter-stock adjustment of the transport belt (12). An iron wheel (19) driven via a chain (18),
The potato (15) of round or cut balls stored in the hopper (11) is scooped up by a transport spoon (20) as a transport member on the surface of the transport belt (12), and the inclined upper end position of the planting gutter (13). To the bottom of the inclined flow (1) of the gutter (13).
3a) is caused to flow down and is discharged into the groove at the inclined lower end.

As shown in FIG. 1, the conveyor belt (12)
Are three belt pulleys (21a) (21b) (21c)
And a spoon (20) forming a depression (20a) in the feed direction is wound around a belt (1).
2) A belt that is attached to the surface and that allows the upward vertical feed portion (12a) of the conveyor belt (12) to face the inside of the hopper (11) and between the inclined upper end of the planting gutter (13) and the hopper (11). The horizontal feed section (12b) of (12) is provided substantially horizontally, and the downstream feed section (12c) between the end of the horizontal feed section (12) and the start end of the vertical feed section (12a) is provided with the above-mentioned planting gutter (13). The vertical feed portion (12a) and the horizontal feed portion (12b) are provided with a spoon (2) at an inclination along the inclined inner peripheral surface (13a).
0), the seeds (15) are held and transported one by one in the depression (20a), and the spoon (20) at the forward position from the depression (20a) of the spoon (20) at the end of the transverse feed portion (12b). The seed potato (15) is moved to the back of the spoon (20) at the back of the spoon (20) in the downflow feeder (12c).
It is configured to convey while regulating the natural flow of the water.

In addition, a transfer guide member (21) is provided between the feed end of the horizontal feed portion (12b) and the feed start end of the flow-down feed portion (12c), and is provided at the feed end of the flow-down feed portion (12c). A substantially horizontal seed pot retaining plate (22) is provided, and when the seed potato (15) from the planting gutter (13) moves onto the stay plate (22), the movement of the seed potato (15) is stopped. When the seed potato is again held in the recess (20a) of the rear spoon (20) away from the back of the spoon (20), it is moved on the retaining plate (22) to discharge from the rear end. , So that the planting pitch accuracy can be stably maintained.

As shown in FIGS. 4 and 5, the planting gutter (13) has an inverted U-shaped cross section, and the tip of the spoon (20) has an arc-shaped inner peripheral surface (G) of the gutter (13). 1
3a) is formed on an arc surface (20a) along the gutter (13).
The gap (t) between the spoon (20) and the spoon (20) is made substantially uniform over the entire circumference of the arc to prevent the seed potato (15) from passing through the gap (t).

In this case, the slack allowance of the belt (12) substantially in the middle of the downstream feeding section (12c) is maximized, and
2c) As a result of minimizing the slack allowance of the belt (12) at the start end, the gap between the feed portion (12c) and the feed portion (1) is reduced.
2c) To increase the gap (t) at the beginning, the gap (t)
The gutter spacer (23) is joined to the inner peripheral surface of the downflow start end portion of the large planting gutter (13), and the gap (t) at this portion is set.
1) is configured to be small.

The spacer (23) is detachably fixed to an adjusting slot (24) of the planting gutter (13) through a bolt (25) and can be adjusted in position to form a spacer (2) having a different thickness.
3) Replacement or mounting position of the spacer (23) with the gutter (1)
3) is provided so as to be adjustable in the longitudinal direction.
The adjusting slot (2) of the mounting plate (26) fixed to the end of (3).
7) The retainer plate (22) is fixed to the upper and lower positions via bolts (28) so as to be freely adjustable, so that the gap (t) between the spoon (20) and the retainer plate (22) can be adjusted. It is composed.

In the apparatus shown in FIG. 6, a transport belt (12) is wound around four belt pulleys (21a) (21b) (21c) (21d) in a substantially inverted trapezoidal shape, and the downstream feed section (12c) is provided. A substantially horizontal rear feed portion (12d) is formed at the end of the feed, and a substantially horizontal seed pot retaining plate (22a) disposed to face the feed portion (12d) is also formed to be long, and the downstream feed portion is formed. The seed potato (15) flowing down from (12c) is securely stopped on the retaining plate (22a), and the spoon (20)
Is moved to the feed end of the stay plate (22a) to discharge at an appropriate pitch.

[0012]

As is apparent from the above embodiments, the present invention provides a method for transferring a seed potato (15) conveyed by a conveying member (20) on the surface of an endless conveying belt (12) to a planting gutter (1).
3) In a potato planter configured to be planted by flowing down, a spacer (23) for reducing the distance between the transport member (20) and the planting gutter (13) to a predetermined value or less is provided by a planting gutter (13). The gap (t) between the transporting member (20) and the planting gutter (13) is partially large, for example, when the thickness of the cut ball of the seed potato (15) is small, or is partially large. In this case, the gap between the conveying member (20) and the planting gutter (13) is adjusted by the spacer (23),
The planting pitch can be properly maintained, and the planting accuracy can be stably maintained.
