Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention produces tape seedlings using a tape seedling making device that stores tape seedlings formed by arranging crop seedling bundles at predetermined intervals in the longitudinal direction of the tape. At the same time, tape seedlings prepared in advance are stored in a seedling storage case and mounted on a seedling planting device, and the tape seedlings are pulled out from the seedling storage case and planted on a screen. Regarding equipment.

[Conventional technology]

Conventionally, in this type of tape seedling planting device, there has been one in which crop seedling bundles are sewn onto a tape and guided into the field as they are for planting (for example, Japanese Patent Publication No. 8808/1983).

[Problem to be solved by the invention]

When adopting the above conventional configuration, the seedlings are sewn onto the tape, so when the tape seedlings are transported from the seedling storage section to the planting section, the posture of the seedlings is less disturbed and adjacent surfaces do not become entangled. Although it has a feature that can prevent this, since the method uses a method of planting seedlings within the screen with the seedlings sewn to the tape, the pitch of the crop seedling bundles to the tape must be equal to the planting interval on the field surface. First, it is impossible to shorten the length of the tape by keeping the attached pitch as small as possible without causing entanglement between adjacent seedlings or comrades; Problems that remained to be resolved include the need to make tapes and sewing threads from weak materials that naturally decompose after a certain period of time so as not to inhibit growth.

The purpose of the present invention is to suppress the entanglement of seedlings in the transportation process from the seedling storage section to the planting section, reduce the amount of tape used, and strengthen the structure by adopting a rational planting form. The point is to provide something that can use tape.

[Means to solve the problem]

The features of the present invention are: 1. A sewing mechanism is provided for sewing bundles of crop seedlings arranged at predetermined intervals in the longitudinal direction of the tape onto the tape; (2) A mechanism for disassembling the crop seedling bundle is provided; and (1) A planting mechanism for planting the separated crop seedling bundle is provided.The functions and effects thereof are as follows.

[For production]

■ Due to characteristic structure (■), the bundle of crop seedlings is sewn to the tape during transportation, so the posture of the bundle of crop seedlings is not disturbed, and there is less chance of entanglement between adjacent seedlings.

At O time, according to configuration ■■, when planting, the thread is untied to separate the crop seedling bundle from the tape, so it is possible to set the crop seedling bundle attaching pinch during transportation by cutting it off from the planting pitch, and the tape
It is not necessary to use a naturally decomposing material such as paper as the material of the thread body, and a strong resin tape can be used.

[Effects of the Invention] According to the effect (2), damage to the seedlings can be reduced by reducing entanglement between adjacent seedlings.

In the first half of action O, if the planting pitch of crop seedling bundles is large, the pinch during transportation can be made shorter than the planting pitch within the range where adjacent seedlings do not become entangled, so that a large number of crop seedling bundles can be planted. The length of tape required for attaching can be shortened.

In addition, from the second half of action ◎, it is no longer necessary to use tape and thread that naturally decompose after planting, as in the past, and it is possible to use tape that is strong enough to withstand transportation. Damage and cuts during transportation are reduced, work stoppages due to cuts, etc. can be avoided, and repeated use is also possible.

〔Example〕

The tape seedling creation device will be explained. As shown in Figure 1, small bundles of rice seedlings (a), which are separated by hand from a large bundle of rice straw, are transported by a pair of left and right conveyor bells) (1)
At the same time, a pair of left and right conveyor bells l-(1) are placed on top of the conveyor heald with the culm along the width direction.
A tape (2) that is located between (1) and moves while supporting the crop seedling bundle (a) is fed out from a feeding roll (3),
Transport Beno? The crop seedling bundle (a) is conveyed using the belt (IL (1)) and the tape (2), and the conveyor belt (1), (
A sewing mechanism (1) for sewing the crop seedling bundle (a) placed on the tape (2) to the tape (2) on the lower side of the terminal
23) and a pair of upper and lower drive rolls (24A) and (24A) that guide the tape seedlings downward after sewing.
B) A storage case (4) is provided for storing tape seedlings that are hung down in a vertically zigzag manner.

The sewing mechanism (23) will be explained. Using the only sewing thread, the vertical moving needle (25) inserts this sewing thread into the tape (2), and the action of this vertical moving needle (25) hooks the thread (9) that has passed through the tape (2) to create a loop. A rotating arm (26) forming a rotary arm (26) is provided.
) into the loop of the preceding thread (9) made with
The loop of the new thread (9) formed by the vertical movement of -25) is inserted through the new thread (9), and the new thread (9) is passed through the loop of the rotating arm (25).
A chain-stitch type sewing mechanism (23) is constructed which adopts a structure in which the thread is held at the thread 26) and is not pulled out. The sewing threads (9) are arranged in two rows on the left and right to stabilize the attitude of the crop seedling bundle (a) attached to the tape (2).

On the other hand, in the seedling storage case (4), the seedling storage case (4)
) The tape seedlings are stored in a zigzag manner by continuously changing the hanging position of the tape seedlings using guide rolls (5) that move from side to side above the tape.

As shown in Fig. 2, this guide roll (5) is fixed to the tip of a support arm (7) fixed to one link of a rotating chain (6) driven in a vertical manner. The arm (7) is bent into an L-shape when viewed from the side, and its tip is positioned on a line connecting the left-right reversal center of the rotation chain (6), so that the rotation chain (6) cannot be moved in a certain direction. Also in rotation, it reciprocates on a line connecting the left/right inversion center. In this way, the guide pin (8) is inserted into the folded part of the tape seedling which is folded in a zigzag manner by the guide roll (5) which reciprocates from side to side, and is suspended and supported. The insertion position of this guide bin (8) is provided only on one of the left and right folded parts, and as shown in Figures 1 and 2, when the tape seedling reaches one of the folded parts, it is inserted at the right time. The guide bin (8) in a standby state is inserted into the seedling storage case (4) by an actuator or manually, and the tape seedling is wound upward and reversed using the guide pin (8) as a fulcrum.

As described above, when multiple stages of tape seedlings are stacked and stored, they are mounted on a traveling machine (not shown), as shown in FIGS. 1 and 2. As shown in the figure, the seedling storage section (4) is installed in a vertical position, inverted by 90 degrees, and has a narrow width to match the planting row spacing (20 cm).

Next, the tape seedling planting device will be explained. As shown in Figure 4, a four-speed link mechanism (10

As shown in FIGS. 4 and 5, a mechanism (13) for separating the crop seedling bundle (a) from the tape (2) is provided at the bottom of the seedling storage case (4). The separating mechanism (13) consists of two guide rollers (14), (
14), a large-diameter drive roller (I5) with a sponge stretched on its outer circumferential surface that pulls and drives the tape seedlings, and this drive roller (
It consists of a tape (2)/thread (9) separation roller (16) arranged opposite to the tape (2) and thread (9), and a winding roller (174) (1713) for winding up the tape (2) and thread (9). Therefore, the tape (
2) and the thread (9) are separated by the driving roller (15) and the separation roller (16), so that the crop seedling bundle (a) is released from the pinching action between the tape (2) and the thread (9). , and fall to the planting mechanism (18).

As shown in FIG. 3, the winding roller (17B) that winds the yarn (9) is loosely fitted onto a drive shaft (27) that is cantilevered over the side plate at the lower end of the storage case (4). At the same time, power is transmitted through contact between the drive shaft (27) and the friction plate (28) which rotates integrally with the drive shaft (27), so that the friction plate (28)-1 can slip against the urging force that presses the friction plate (28)-1 into contact with it. It has become. In this case, the rotational speed of the take-up roller (17B) is
9) is set faster than the tape feed speed that unravels.
It is designed to be wound with a certain amount of slip and a constant tension. The friction contact mechanism by the friction plate (28) allows the left and right yarns (9) to be wound one cola (1
7A) and (17B) is adopted to absorb the difference in slip ratio. In the figure (29) is a manual sprocket.

Further, the tape take-up roller (17A) is also provided with a slip mechanism that keeps the tension constant, and the tape/thread take-up roller (17A), ( 17B) is designed to have a high rotational speed so that it can be wound without slack. Furthermore, the rotational speed of the yarn take-up roller (17B) is set high between the take-up rollers (17A) and (17B).
