Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a plug seedling transplanter that is capable of taking out plug seedlings using clamping claws from a plug tray fed out to the rear side of the machine body and transplanting them to a field.

[Prior art] In this type of conventional plug seedling transplanter, the plug tray is intermittently fed vertically and moved back and forth in the horizontal direction to remove the seedling from the pot at a position corresponding to the planting claw. The structure was such that the claws grabbed the plug W and moved it as it was (-1).

[Problems to be Solved by the Invention] Therefore, since the plug tray is reciprocated in the horizontal direction, the center of gravity of the aircraft shifts to the left and right, making it difficult to maneuver and reducing the straight line performance of the aircraft. The problem was that the size of the tool was increasing.

[Means for Solving the Problems] The present invention solves the problem of using tools and makes it possible to carry out transplanting work with good maneuverability. Behind the feeding base, a winding rotary body that feeds out the plug tray on the front side while winding it up is mounted on a shaft so as to be able to rotate intermittently, and behind the winding rotary body, the plug tray is The two parts of the flexible seedling guide chute are equipped with horizontally reciprocating clamping claws that can rotate downward while gripping and removing plug seedlings from the bot, and the lower discharge port side is fixedly supported. It is constructed in such a way that it is interlocked with the gripping claws on the lower side so that they can move laterally.

[Function] Therefore, while the rotating body winds up the plug tray that is sent out backwards and rotates intermittently while winding up the plug tray, the gripping claws move laterally and one by one from the bots in the horizontal direction of the plug tray. The plug seedlings can be grabbed and placed directly into the upper part of the seedling guide chute that moves with the clamping claws, and the plug seedlings fall inside the deformed seedling guide chute and are transplanted to the predetermined planting position. It turns out.

Examples] Next, the embodiment shown in the drawings will be described.

In the center of the front of the aircraft, which has an engine (8) in the recess, both axles (9) on both sides, and both handles (10) at the rear, is a pot (a>) loaded with plug seedlings (B). Place the plug trays (A), which have many vertically and horizontally, and
A belt-type feeder (1) that can be fed out is installed obliquely, and behind the feeder (1) are curved guide rods (11) that can contact and guide both sides of the plug tray (A).
) mounted on the outer periphery of both sides, the winding rotary body (2) is driven by a motor (12).
11ull (2a) is transmission connected to the feed base (1) via the pulley bell 1- (13), and the side sensor (
The winding rotating body 2) and the feed table 1 can be rotated intermittently by detection by 20).

Plug) by the winding rotating body (2)! Hui (A
) is installed so that the plug tray (A) can be sent out from below to the lower side of the feeding table <]), and the plug tray (A) can be fed forward from the bottom side of the feeding table <]) while winding up the plug tray (A). Since (A) is not curved, a cylindrical body <211> is constructed so that the bottom surfaces of the bolts and (a) can come into contact with each other. A crank-shaped horizontal rod <5> that can be rotated in the outer circumferential direction so as to be able to pivot in the direction of the outer periphery so as to be able to pivotally support the 5 u) and fit between the 6 bons 1 to 6 (a) (a) in the transport direction.
51! They are hung horizontally at intervals, and each horizontal rod (5) has a stopper (
14) is installed by applying ++lF pressure in the outer circumference -JJ° direction by torque springs (15) on both sides until rP) is reached, and a perforated protrusion is provided at the bottom Jj of the 5-winding rotating body (2) at the center of the outer circumferential surface. (16) - Drums (17) arranged at regular intervals are freely rotatable and mounted on a shaft 2, between the rear portions of both stays (18) extending rearward from both sides of the drum (17). A photoelectric switch-type perforation detector (19) that detects perforations has been installed with adjustable forward and backward movement! , horizontally.

- Inside the boulder (31), the bases of three long clamping claws (3) arranged at three equal intervals are each pivoted to a shaft 32), and a projecting piece protrudes from the base of each clamping claw (3). (3a) has T'
When the compression spring (33) is brought into contact with the compression spring (33) from the front side, the pin (30+i) moving in and out of the bottle cylinder (30) is brought into contact with the bottom (1-), and the bracket (25) is Four parts (34a
) (34b) in the longitudinal direction is removably fitted and constructed, and the sensor (35) provided on the bracket (25) engages with the recesses (34a) and (34b). Then, the motor (22) is stopped, and the configuration can be applied to the case where the pitch between the pots in the lateral direction of each plug 1 to the lay (A) is different.

There is a seedling guide chute 4 on the lower side of the clamping claw (3).
The seedling guide shooter (4) is formed by assembling four flexible spring rods (4a) so that the plug seedlings (B) can flow down the inside thereof, and serves as a discharge port. The lower part of the seedling guide shooter (4) is fixed and supported by a holder (36) between the rear parts of both stays (18) so as to be in the rear position of the perforating projection (16), and the cap (4b) is attached. The upper part of the seedling guide shooter (4) is positioned below the vertical clamping claws (3).
5) A freely rotatable holder (
38).

Figures 12 to 14 show the seedling guide shooter (4).
Other embodiments are shown, in which two spring plates (4c) or two bent spring plates (4a) are used instead of the spring rod (4a).
d) or a four-wood flexible pipe with empty spout (
4e) are combined.

Therefore, the plug tray (A) is placed above the feed base (1).
When placed, vertical feeding is possible intermittently, and when the plug tray (A) winds up and engages with the rotating body (2), the horizontal rod (5), which is pressed in the outer circumferential direction, The plug tray (A>, which is deeply inserted between adjacent pots (a Ha ) in the direction and is in a curved state, is supported and engaged while being pressed so that it does not bend, and as it is,
The empty plug tray (A) is fed vertically intermittently to the lower side of the feed base (1), and as the machine moves forward, the perforated protrusion of the drum (17) rotates. <16), a concave hole is formed in the field as shown in the drawing.

In this state, when the clamping claws (3) stop as detected by the sensor (35) while being fed horizontally by the feeding mechanism 23), the seedling cylinder (29) moves as indicated by the arrow (a).
The tip of each clamping claw (3) that is pushed out in the direction of the pot (a
Then, by the operation of the bottle cylinder (30), the pin (30a) moves in and out, rotating each clamping claw (3) around the shaft (32). The plug seedling (B) can now be clamped, and when the plug seedling ([3) is taken out and the perforation detector (19) detects a perforation, each clamping claw (3)
The axis 27) Rotates around the center and becomes vertical! While getting started,
It will open and drop the plug seedling (B), and the clamping claws (3
) The plug seedlings (
B) flows down as it is, is released from the bottom into the perforation in the field, and is transplanted.

[Effects of the Invention] As described above, the present invention provides a winding rotating body (2
), the plug tray (A) can be wound up and the plug seedlings (B) can be taken out without moving laterally, so the width of the machine can be narrowed and the machine can be made smaller. This improves straight-line performance and makes it easier to maneuver, and the gripping claws (3) that pick up the plug seedlings (B) one by one while moving laterally allow them to be fed into the seedling guide shooter (4) in a good manner. At the same time, it became possible to plant at a designated planting position from the bottom.
This means that the transplant work can be performed with high precision, and has the advantage of being suitable for implementation.
