DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable transplanter for planting cabbage, lettuce, and the like in a ridge, and more particularly to a device for scraping soil attached to a beak for piercing a transplant tube.

[0002]

2. Description of the Related Art A transplant tube is provided which is capable of ascending and descending and drilling a planting hole in a ridge at the time of descending to plant a seedling loaded therein.
This transplanting cylinder has a beaker which can be opened and closed at the lower part, and a vegetable transplanter equipped with a scraper for peeling off the adhered soil on the outer periphery of the beak is known from Japanese Utility Model Laid-Open No. 59-16315, and removes the adhered soil. Therefore, the planting hole is not expanded, thereby preventing the falling of the seedling.

[0003]

According to the technique disclosed in the above publication, one lifting device is provided on a lifting arm, and the other is provided on an operating arm provided on a lifting arm via a connecting rod. Since each was provided on a separate member, the operation of the pair of scrapers was likely to be out of order.

[0004] Further, the scraper becomes a hindrance to the beak for perforation, causing enlargement of the planting hole and high perforation resistance. Therefore, the present invention eliminates the inconsistency of operation by providing the scraper with a link means in the transplanting cylinder, and by forcibly returning the scraper to the retracted position quickly after scraping, without causing the scraper to hinder the drilling operation. Another object of the present invention is to prevent the planting hole from expanding and to reduce the perforation resistance.

[0005]

According to the present invention, there is provided a transplant tube 1 which can be freely moved up and down, and in which a planting hole 7 is drilled in a ridge 6 at the time of descending to plant a seedling 9 loaded therein. It has a beak 3 that can be opened and closed at the bottom and the beak 3
In order to achieve the above-mentioned object, the following technical measures are taken in a vegetable transplanter provided with a scraper 18 for peeling off the attached soil A on the outer periphery of the vegetable transplanter.

That is, the present invention relates to the above scraper 1
An actuating member 8 is attached to the transplanting tube 1 via link means 23, and is provided with an actuating member 26 in the vicinity of the elevating trajectory 5 of the implanting tube 1 to be disengaged from the actuating member 26 to detach the scraper 18. The body 22 is provided on the link means 23, and a rapid return means 25 for rapidly returning the scraper 18 to the retracted position via the link means 23 is provided.

[0007]

The transplanting cylinder 1 having the openable and closable beak 3 at the lower portion is moved up and down along the ascending and descending locus 5 by the ascending and descending link means 4, receives the seedling 9 at its upper dead point, and receives the beak 3 at its lower dead point. Then, the seedling 9 is transplanted to the ridge 6 by raising the beak 3 while opening it.

When the soil A adheres to the outer peripheral surface of the beak 3, the actuated body 22 engages with the actuating member 26 to peel off the scraper 18 through the link means 23, and the actuated body 22 is actuated. When the scraper 18 leaves the scraper 26, the scraper 18 is quickly returned to the retracted position by the quick return means 25.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The transplanting cylinder 1 is a quadrangular or round cylindrical body in plan view, and has a pair of perforating beaks 3 that can be opened and closed around a fulcrum pin 2 at the lower part thereof. Elevating link means 4 is connected to the transplanting cylinder 1, and the linking means 4 is moved up and down by a cam, a crank, or the like, so that the transplanting cylinder 1 can be moved up and down along an up-and-down locus 5. In the closed state, the planting hole 7 is drilled in the ridge 6 and then
During the ascending process, the beak 3 is opened by the opening / closing link 8 so that the seedlings 9 loaded at the top dead center can be transplanted at intervals in the longitudinal direction of the ridges 6.

In the embodiment, the ridge 6 is covered with the multi-film 10 and the film 10 is pierced by the burner means 11 prior to the perforation of the planting hole 7. On the other hand, a windproof cover 12 is provided so that the fire is not extinguished by a cross wind or the like. On the other side of the lifting link means 4, a pair of front and rear upper link arms 14 are pivotally attached to the side of the transplant tube 1 around a fulcrum pin 13, and the upper link arms 14 are supported at the lower portion of the transplant tube 1. A pair of front and rear lower link arms 16 that move about the pin 15 are connected via connecting pins 17 to the middle of the pair of front and rear lower link arms 16, and each end of the lower link arm 16 is provided with a pair of front and rear scrapers 18 made of a leaf spring or the like. The scraper 18 faces the front and rear of the beak 3.

The implant 1 has a bracket 19 protruding forward.
The bracket 19 is provided with an operation link 21 via a pin 20. The operation link 21 has an actuated body 22 exemplified by a roller at a front end and a fulcrum pin 13 at a rear end.
The upper and lower link arms 14 are interlocked with each other, and the front and rear pair of scrapers 18 are provided on link means 23 that is symmetrical in front and rear.

The operating link 21 swings on the pin 20 as a fulcrum, and the pair of scrapers 18 can be held at the retracted position (the posture at the time of the top dead center of the transplantation cylinder) by the stopper 24 and provided on the pin 20. Urged to the retreat position by a quick return means 25 indicated by a coiled torsion spring. An actuating member 26 is fixed in the vicinity of the elevating trajectory 5 of the transplantation tube 1. When the actuated body 22 abuts on the actuating member 26, the actuating link 21 is opposed to the quick return means 25.
Swings on the pin 20 as a fulcrum, and the upper and lower link arms 1
When the scraper 18 performs the peeling operation of the soil A attached to the outer peripheral surface of the beak 3 via the 4, 4 and the actuated body 22 separates from the operating member 26, the scraper 18 is moved by the quick return means 25 to the retracted position (elevated position). It is designed to restore quickly.

Therefore, in the embodiment shown in the drawing, the seedling 9 is received with the beak 3 closed at the top dead center of the transplant tube 1, and the ridge 6 is raised at the bottom dead center of the transplant tube 1 after piercing the ridge 6 with the beak 3. The beak 3 is to be opened and transplanted in the process, and the beak 3 is closed in the process of shifting from the bottom dead center to the top dead center. And the soil A attached to the outer peripheral surface of the beak 3
When the actuated body 22 comes into contact with the operating member 26 in the process of lowering the transplant cylinder 1 from the top dead center to the bottom dead center, the scraper 18 is lowered via the link means 23 to be peeled off. Before reaching the dead point, the actuated member 26
Is removed, and the scraper 18 is retracted and returned by the quick return means 25, thereby eliminating the perforation obstacle caused by the beak 3.

It should be noted that the present invention can be applied to both a walking type and a riding type transplanter, and it is desirable that the position of the operating member 26 can be adjusted and fixed.

[0015]

As described above in detail, according to the present invention, the scraper can be synchronized with the scraper to reliably remove the soil adhered to the outer periphery of the beak. In addition, here, the expansion of the planting hole can be prevented, and the drilling resistance can be reduced.
