Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seedling feeding device for a transplanter for transplanting seedlings, such as onions, at regular intervals.

(Prior art) As a conventional transplanting machine for onions, etc., there is a
There is one disclosed in Publication No. 91. This conventional seedling delivery device of a transplanter has a second transfer conveyor with a large number of pick-up members arranged in a row interposed between the first transfer conveyor below the seedling box and the planting disk. The first on the transfer conveyor
A conveyance path is formed generally perpendicular to the transfer conveyor, and the seedlings on the first transfer conveyor are picked up one by one by the second transfer conveyor, and the seedlings are planted and supplied to the disk.

(Problems to be Solved by the Invention) In the prior art described above, seedlings can be continuously fed out at regular intervals using the pick-up member of the second transfer conveyor, but if the roots of the seedlings are entangled, the pick-up member of the second transfer conveyor There is no means to untangle the roots before reaching the transfer conveyor, and one pick-up member sometimes picks up multiple seedlings, and it is difficult to shake off adhering soil.

Therefore, as shown in Figure 4, a sorting sieve (21) and a conveyor with fins Q4' are placed between the seedling box (6) and the planting disk (7), and the seedlings (8 ) may be configured to disentangle the roots, correct the posture, and shake off attached soil while transporting the seedlings, and transport the seedlings at regular intervals using a conveyor with fins (141').

However, in the feeding device shown in Fig. 4, the seedlings (9) are fed falling from the sorting sieve to the fin conveyor σ, and it is guaranteed that only one seedling (8) will fit between the fins (14a). If there is no seedling, seedlings of multiple sizes may enter the plant or may not enter at all, leading to the occurrence of missing plants.

(Means for solving the problem) The uninvented method solves the problems of the prior art by using a seedling box (6).
By providing a sorting V-bub P211 and a suction feed mechanism □□□ between the mechanism αQ and the planting mechanism αQ, all problems can be solved.

In other words, the specific structure of the uninvented problem-solving means is characterized by a seedling feeding device of a transplanter that continuously sends seedlings from a seedling box to a mechanism for planting them at regular intervals. There is a sorting sieve that receives seedlings that are delivered in excess of the quantity, separates them, and transfers them while sorting them, and a sorting sieve that is located below the end of this sorting sieve and picks up the seedlings one by one after sorting and then plants them. The main feature is that it has a suction and feeding mechanism that feeds it to the mechanism.

(Operation) The seedlings (9) taken out from the seedling box (6) are sorted through the sorting sieve 1.
), the roots are disentangled and adhering soil is shaken off, and the amount of soil for planting is supplied to the adsorption/feeding mechanism (e), which adjusts the planting speed accordingly. Mechanism a allows you to securely plant one seedling at a time while adsorbing the seedlings.
Move to Q.

('$, example) Hereinafter, uninvented embodiments will be explained based on the drawings.

As shown in Figures 1 to 8, the onion transplanter (11 is attached to the rear of the tractor body + 21 via an 8-point linkage mechanism (3), and its power is supplied from the PTO shaft (4) of the tractor body (11). ) is transmitted from.

(6) is the machine frame of the transplanter (11), (6) is the seedling box attached to the top of the machine frame (6), (7) is the horizontal axis (8) attached to the machine frame (5)
The planting is rotatably supported through a disk, and (9) is a soil-covering wheel, which is arranged on the left and right of the planting disk (7) and supported on the machine frame 151 so as to be rotatable about a horizontal axis. (1ω is the machine frame in front of this earth-covering compaction wheel (9): 5) K is installed with a nine-groove device, and this groove-maker (lO) is used to cut a round groove, and the planting is a disk (7). The machine rotates to perform the planting work. (b) is a gauge wheel that can adjust the groove depth.

α◆ is a belt conveyor placed at the rear of the machine frame (5), which can transfer the seedlings while delivering the planted seedlings to the disk ()). (g) is driven in the direction of the arrow in FIG. 1 by power being transmitted from a gear case (to) provided at the front end of the machine frame (5).

The seedling box (6) and planting are carried out using Mechanism αQ's belt conveyor a◆
A seedling feeding device (1) is arranged between the two. This seedling feeding device (E) is appropriately supported by the machine frame i51K, and power can be transmitted from the gear case (to). It has a suction roll device disposed below the terminal end of the sorting sieve (21). A glance at the suction roll is shown in the gear case (
2) is connected to the vacuum device (241) attached to the back side through hoses, and the suction roll (to) and the vacuum device (24) constitute a suction feed mechanism.

The seedling box (6) and the sorting sieve (21) are each supported by a swing arm so as to be swingable in the front-rear direction (seedling transfer direction). A large number of onions and other seedlings are stored in a pile in the seedling box (61), and are sequentially fed out from the feeding row at the bottom side of the seedling box and supplied to the starting end side of the sorting sieve (211).

The sorting sieve (21) uses its serrated shape and vibration to loosen the entangled roots of the seedlings and separate them one by one, correcting the seedling's posture parallel to each other, and while acting as such, it also prevents attachment. After shaking off the soil, it is transported to the front of the building.

The seedlings (A) dropped from the sorting sieve are fed by falling to the suction roll (roll) without losing their posture by a downwardly tapered guide device.

The suction roll is driven to rotate in synchronization with the belt conveyor α◆, and has a plurality of recesses (32) formed at equal intervals on its outer peripheral surface parallel to the axis, and each recess (32 has at least one recess). A suction port (G) is formed, and this suction port can be communicated with the hose @5! via a suction path.

This suction roll (匈) rotates for approximately half a rotation from just before reaching the bottom of the guide □□□ to above the belt conveyor α fathom.
The suction port @31 communicates with a hose and can suction the top of the screen.

The direction of the head and leaf part of the seedling (6) is set when it is placed in the seedling box (6), and when it falls inside the guide tube 4,
The side wall (22a) corrects the position of the head in the left-right direction so that it corresponds to the suction port of the suction roll.

- is a receiving box for receiving surplus seedlings on the opposite side to the rotating direction of the suction roll device, and is attached to the machine frame (5) and
is an angle-adjustable or swingable distribution plate for distributing surplus seedlings approximately evenly into receiving boxes.

The inside of the suction roll has a structure in which the falling seedling (6) is stopped by a concave part and its head is adsorbed, so there is a possibility that the fall of the seedling and the rotation of the concave object do not match. There is sex. Therefore, the amount of seedlings supplied from the sorting sieve (2p) is set to be larger than the amount of seedlings to be planted, and the suction port is used.

In the above embodiment, although the rotational direction of the suction roll and the conveyance direction of the belt conveyor α◆ in FIG. 2 are different from those in FIG.
1 may be provided with an auxiliary seat so that an auxiliary worker can ride on the side of the sorting sheave (21).

(Effects of the Invention) According to the Maruki invention detailed above, the seedlings (8) taken out from the seedling box (6) are untangled from their roots while being transferred by the sorting sieve (211), and It is possible to divide the plants into thick portions, and also to shake off the adhering soil, and in the divided state, the plants are adsorbed by the suction roll! 231 of the suction feed mechanism and sent to the Sakaki mechanism for planting. , Seedling (8) is l
It is possible to supply A and Fc from each thickness, ensuring constant interval feeding of each thickness.
