Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] In the present invention, a crop seedling bundle separated for each strain is attached at a predetermined interval in the longitudinal direction of the tape, and the crop seedling bundle is separated for each strain. The present invention relates to a tape seedling transplanting machine provided with a separating device, and a planting claw for planting a crop seedling bundle separated by the separating device on a field surface.

[Conventional technology]

In this type of tape seedling transplanting machine, conventionally, a cutting blade is provided on a planting claw like the one proposed by the present applicants in FIGS. 1 and 2 of Japanese Patent Application No. 63-240092, for example. The tape seedlings fed to the cutting position were cut, and at the same time, they were held and planted by the planting claws.

[Problems to be Solved by the Invention]

In this case, the timing for holding and planting with the planting claws is set almost at the same time as cutting, so for example, the seedlings that are still moving due to the impact of cutting will be grasped by the planting claws. Sometimes my nails didn't work when I tried to hold them.

An object of the present invention is to provide a device that can reliably hold seedlings with planting nails by additionally configuring a rational mechanism.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that a seedling receiving tool for maintaining the separated crop seedling bundle in a standby position before being held by the planting claw is provided, and the seedling receiving tool is configured to receive the separated crop seedling bundle. In the action posture to stop, the state is set so as to face the operation locus of the planting claw, and when the separated crop seedling bundle is taken out by the planting claw, it is switched to a state of withdrawing from the operation locus of the planting claw. The mechanism is provided, and its operation and effect are as follows.

[Work]

In other words, the separated plant seedling bundle is once received by the seedling receiving device located within the locus of the planting nail, and the planted seedling bundle in this receiving state is held and planted by the planting nail. When the nail operates to hold the crop seedling bundle, the seedling catcher exits the path of the planting nail to avoid interference.

〔The invention's effect〕

Therefore, by providing a catch that temporarily receives the separated plant bundle, it is possible to switch to a stationary state and hold or lock the planting claw to start the planting operation. The effect of catching the crop seedlings can be ensured, and the lack of plants and floating seedling phenomena can be avoided.

Moreover, by the configuration that the seedling receiving device can be withdrawn from the locus of the planting nail, it is possible to adopt a configuration that only receives the plant seedling bundle within the locus of the planting nail, for example, the stem tip of the plant seedling bundle. Compared to a fixed-holding type seedling holding device that holds the planting claw outside the locus of the planting claw and keeps it in a standby position, the planting claw only catches it when picking it out, so that it may damage the crop seedling bundle. Less is.

〔Example〕

A tape seedling transplanting machine, which is attached to a traveling machine body (not shown) and which is used to plant a crop seedling (b) such as straw grass or rye, will be described.

This crop seedling bundle (b) is manually separated into a small bundle of crop seedlings (b) from a large bundle of mother plants, and a pair of continuous tapes (1
Tape seedlings formed by sandwiching the tapes (1A) and (1B) at equal intervals along the longitudinal direction of the tapes (1A) and (1B) are spelled in the seedling storage section (2) in a vertically overlapping manner. It is stored in a fold. Then, the tape seedlings are stored in the seedling storage section (2).
It is configured to be taken out from the seedling take-out port (2A). Below the seedling take-out port (2A) of the seedling storage section (2), planting claws (3)
A conveyor belt (4) for guiding the conveyor belt (4) and a guide plate (5) for guiding the conveyor belt along the conveyor path are provided, and the outlet side of the conveyor belt (4) is shaken. A tape cutting mechanism (6) consisting of a moving cutting blade (6A) and a fixed receiving blade (6B) is provided to form a separating device for separating the crop seedling bundle (b) with each tape while holding it.
In the figure, (7) is a holding tool that improves the cuttability by pressing the tips of the tapes (1A) and (1B) when cutting.

The crop seedling bundle cut by the tape cutting mechanism (6) is dropped in the form of a drop chute (8) with its root part facing downward, and the seedling receiving tool (9) is used to hold it before the holding posture by the planting claw (3). Maintained in the standby position. This seedling receiving device (9) has a separated crop seedling bundle receiving action posture facing the crop seedling bundle dropping space through the notch of the drop chute (8) and a non-acting posture leaving the crop seedling bundle dropping space. In order to be switched, the swinging arm (10) for driving the planting claw (3) is linked to the link (11). Therefore, the operation locus (a) of the planting claw (3) in response to the timing when the planting claw (3) holds the plant seedling bunch (b) while receiving the separated plant seedling bundle.
It is designed to switch to a more inactive posture. The link mechanism (11) is referred to as a switching mechanism for switching the seedling receiving device (9) to the working posture and the non-working posture.

As a means for driving the tape cutting mechanism (6) and the conveyor belt (4), a transmission case (12) which receives power from a traveling machine body (not shown) is provided, and the transmission case (12) is also provided.
A mechanism for extending and extending the output shaft (13) to the drive pulley (4A) of the conveyor belt (4) is provided, and on the other hand, a swinging cutting edge (6A) is intermittently provided on the lateral surface of the transmission case (12). A rotating arm (16) for driving is provided.

The planting claw (3) includes a pair of left and right claws (3a), (3a) attached to the tip of the planting arm (14), a spring (3b),
(3b) closes and urges the planting arm (1
Interlocking with the planting operation of 4), the pair of left and right claws (3a),
A cam member (15) for opening and operating (3a) is axially supported so as to be rotationally driven around an axis (X). The cam member (15) has cam surfaces formed on both side surfaces. Therefore, the crop seedling bundle (b) is grasped in the closed state and switched to the open state at the time of planting.

[Another embodiment] As shown in Fig. 4, a plurality of seedling storage parts (2) are arranged side by side so that a plurality of rows of plants can be planted, and a bundle of crop seedlings held in a sideways posture is held by a tape. In this state, it is pulled out from the seedling storage section (2) and dropped, the posture of the crop seedling bundle (b) is switched to the front-back direction and cut by the cutting mechanism (6) and discharged onto the drop chute (8). The drop chute (8) is equipped with a seedling receiving device (9) to receive the seedling in the seedling falling space and to leave the seedling falling space by the seedling holding action of the planting claw (3).

Two tapes (1A) are used as a tape seedling creation structure.
Instead of holding the crop seedling bundle (b) in (1B), a configuration may be adopted in which it is attached to a single tape (1A or 1B) via an adhesive.

As a structure for separating the crop seedling bundle (b) for each strain,
The two tapes (1A) and (1B) may be forcibly separated from each other to spontaneously drop or scrape the crop seedling bundle (b) to separate them.

As the switching mechanism (11), a dedicated actuator for swinging the seedling receiving device may be provided.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
