Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a seedling planting device for planting a root-washing crop seedling bundle that does not retain soil mainly in the roots of strawberries and the like. A plurality of bundles of crop seedlings that have been divided from the mother plant are placed on the seedling surface of the moving seedling stand, and a vertical feed mechanism that sends this crop seedling bundle toward the seedling take-out port is provided,
The present invention relates to a seedling planting device provided with a planting claw for picking up, holding and planting a crop plant seedling bundle fed to the seedling takeout opening.

[Conventional technology]

In this kind of seedling planting device, conventionally, no special mechanism is applied to the planting site near the bottom dead center in the operation locus of the planting claw, and the planting site is simply planted at the planting site that has been prepared by the leveling float. The seedlings retained by the artificial nails were released and planted (for example, Japanese Patent Application No. 63-278155).

[Problems to be Solved by the Invention]

However, in this case, since the planting seedlings are brought in and planted on the field surface only by the operation of the planting claws, the rooting of the crop seedlings is bad and the posture of the planting seedlings is particularly bad when the field surface is hard. There was a phenomenon in which the seedlings were disturbed or the seedlings that should be planted on the planting surface adhered to the planting nails and lifted up, resulting in poor planting such as floating seedlings. In particular, such a phenomenon occurred remarkably in a bundle of crop seedlings that did not have root soil such as straw grass.

An object of the present invention is to provide a plant which can prevent planting defects such as floating seedling phenomenon by additionally configuring a simple mechanism near the planting site.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that a rear open type grooving device having a substantially U-shaped cross section is provided in front of a planting position near a bottom dead center in an operation locus of the grooving claw, and a side of the grooving device. There is a point that the rear end of the part is extended to near the lateral side of the planting part by the planting claw, and the action and effect thereof are as follows.

[Work]

Due to the characteristic configuration, the groove is formed in the planting surface prior to the planting by the grooving device, and the substantially U-shaped cross section prevents the inflow of mud into the groove from the front and the sides. The planting claws are used to bring in a plant seedling bundle and plant it in the trench protected by the substantially U-shaped grooving device.

Moreover, because the rear end of the side part of the grooving device is set to the position described in the characteristic configuration, there is soil inflow from the rear end of this side part into the groove, and the root part of the crop seedling immediately after planting is filled. return.

〔The invention's effect〕

Therefore, by providing a grooving device, it is possible to form a groove for dropping the root part of the crop seedling bundle, and the stability of the planting posture can be improved as compared with the case where the planting surface is simply planted with a leveling float. Moreover, by setting the side rear end of the grooving device as described above, backfilling can be performed at the timing of planting, a stable planting posture can be maintained, and a plant seedling bundle can be planted with nails. It is possible to prevent people from carrying about.

Those having such a structure are particularly effective for planting root-washing seedlings such as straw grass that does not retain root soil.

〔Example〕

The seedling planting device (A) for strawberries which is attached to the rear end of the traveling machine body (figure body) via the elevating link mechanism (1) will be described. As shown in FIG. 1, this seedling planting device (A) comprises a seedling stand (2) that reciprocally moves laterally with a constant stroke, and a feed case (3) that receives power transmission from the traveling body (figure) side. , A plurality of planting cases (4) extending rearward from the feed case (3), and planting arms (5) pivotally supported on both lateral sides of the planting case (4).
A planting claw (6) attached to the tip of the planting arm (5), and a leveling float (7) arranged below the planting case (4).

Next, the structure of the seedling stand (2) will be described. As shown in FIG. 2 and FIG. 3, this seedling stand (2) is divided into a plurality of places corresponding to the number of planting rows, and each row contains a plurality of rows of crop seedling bundles. For this crop seedling bundle group, a plurality of resin plate partition walls (8) for partitioning adjacent seedling groups for each column are arranged side by side, and the plurality of partition walls (8) are at their upper ends. It is supported by round bar frames (9A) and (9B) that laterally pass through the and lower ends. These round bar frames (9A) and (9B) are the partition walls (8) at one end.
It is cantilevered and can be inserted and assembled with other partition walls (8) from its free end, and a plurality of partition walls (8) for planting as one unit as a seedling stand ( 2) It is detachably attached to and supported. Then, the plant seedling bundles (a) divided from the mother plant are housed vertically in a line between the adjacent partition walls (8) and (8), and the roots of the respective housed plant seedling bundles (a) are placed on the seedling support plate. The seedling support plate (21) and the partition walls (8) and (8) are integrally mounted on the seedling support table (2) by an operator, and the seedling support plate (21) is removed. And can be planted. Below this seedling support plate (21), there is provided a belt type vertical feed mechanism (10) for feeding the crop seedling bundle (a) toward the seedling take-out port (b). 10) is constructed by bridging the seedling stand (2) over an idle wheel (11) at the upper end and a drive wheel (12) at the lower end.
The drive wheel (12) is linked via a link mechanism (13) to a rotary arm (14) that constantly rotates on the lateral side surface of the feed case (3), and receives a driving force of the rotary arm (14). The lateral feed end of the seedling stand (2) is configured to operate at a predetermined angle.

Next, the structure of the planting nail (6) will be described. As shown in FIGS. 4 (a), (b), and (c), the planting claw (6) has a channel-shaped cross section, and a notch (6a) is formed so that the tip end side portion expands toward the tip end side. Then, the cutout portion (6a) constitutes a space through which the stem tip of the plant bundle (a) falls. Then, below the planting claw (6), an extruding tool (18) for pushing out the crop seedling bundle (a) held by the planting claw (6) at the bottom dead center of the operation locus of the planting claw (6). ) Is provided, and the pushing tool (18) includes a proximal movable rod (19) supported by the planting arm (5) and an pushing piece (20) fixed to the tip of the rod (19).
