Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a feeding device for a seeding machine, and can be effectively used for sowing seeds such as fallen seeds.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION Insertion holes into which a single seed is loosely fitted are arranged radially, and seeds other than those which are loosely fitted into the insertion hole are placed on a rotating feeding disk. In a dispensing device that is equipped with a brush that slides on a dispensing disc for removing seeds, the brush can hold a certain amount of seeds that loosely fit into the insertion hole, but the action of the brush repels one seed, causing the insertion hole to become loose. There is a risk that even the necessary seeds inside may be repelled.

Means for Solving the Problems This invention provides a feed-out disk (2) which rotates at an incline and has insertion holes (1) radially disposed in which each seed is loosely inserted into the insertion holes (1). This feeding disk (2) is placed on the feeding disk (2) between the supply port (3) for supplying seeds to the insertion hole (1) and the drop port (4) for dropping the seeds loosely fitted into the insertion hole (1). 2) A structure of a feed-out device of a seeding machine comprising an elastic roller (5) that slides in contact with and rotates to restrict a single seed to fit loosely into the single insertion hole (1). do.

Functions and Effects of the Invention The seeds supplied from the supply port (3) onto the rotating dispensing disc (2) fit loosely into the insertion hole (1) as appropriate, and
When it reaches the lower side of the roller (5) as the roller (5) rotates, the insertion hole (1)
A single seed is pressed into the hole (1), and the excess seed is removed to the outside in the direction of rotation of the insertion hole (1).
When the single seed of 1) reaches the falling hole (4), it will fall into the falling hole (4).
) and are sown.

In this way, there is no risk of removing the single seed required in the insertion hole (1), and a single seed can always be secured in the insertion hole (1), so a constant seeding amount can be maintained. can be maintained accurately.

Embodiment In the illustrated example, the support member (8) is a box-shaped feeding case (7) in which the negative side of the bottom part (6) is formed into a semicircular shape in plan view, and this semicircular side is tilted downward as much as possible. A vertical shaft bearing part (9) is provided at the lower center of the bottom part (6).
The shaft bearing part (9) has an upper end connected to the bottom part (6).
) The drive shaft (!0) is supported on the drive shaft (10), and the protrusion of the drive shaft (10) has an insertion hole (!0) into which a single seed is loosely fitted.
A feeding disk (2) with holes 1) arranged radially is fixed, and a hole having the same diameter as the insertion hole (1) is placed on the upper side of the feeding disk (2) at the position of the insertion hole (1). An adjusting plate (1) having a hole (1) is provided on the feeding disk (2) so as to be rotatably adjustable.

On the upper side of the adjustment plate (1), there is a funnel-shaped bottom part 0 having a supply port (3) at a tilted downward position of the adjustment plate (II) and a semicircular wall of the feeding case (7). A seed hopper 041 for supplying seeds to this supply part f+31 is installed on the upper side of this supply part (13), and a seed hopper 041 is installed on the lower side of this supply part (13). The supply port (3
) to guide the seeds falling from the feed port (3) on the bottom (6) of the feeding case (7).
A seed drop opening (4) communicating with the sowing pipe (IG) is provided at a position opposite to the sowing pipe (IG).

A plate-shaped mounting member (m) located above the drop port (4) is provided on the side wall of the supply section (13), and each of the mounting members (m) has a shaft bearing portion at its lower end. A two-pair arm body (1) is attached to the arm body (1), and a shaft (1) supporting an elastic roller (5) that rotates in sliding contact with the adjustment plate (II) is attached to the shaft bearing part of this arm body (1). Support one.

Next, the effect will be explained. Seeds in the seed hopper (1
19 and falls onto the feeding disk (2), and is about to be transferred in the rotational direction by the rotation of the feeding disk (2).

Most of the seeds slide down due to the inclination of the feeding disc (2), and when the seeds that have fit into the insertion hole (1) and the residual seeds that remain above or around the seed reach the roller (5),
The remaining seeds are divided by 9 in the rotating direction of the feeding disk (2) by this roller (5) which rotates in sliding contact, and only the seeds in the insertion hole (1) fall into the seeding pipe fIQ from the drop opening (4). The seeds are sown.

As shown in Figure 2, the insertion hole (1) of the feeding disk (2)
On the other hand, by adjusting the rotation of the adjustment plate 1)) and appropriately shifting the insertion hole fil of the adjustment plate (II), the shape of the insertion hole (1) can be approximated to the shape of the seed. It becomes difficult for seeds other than a single seed to fit into this approximate insertion hole (1), which has the effect of further improving sowing accuracy.

FIG. 3 shows another embodiment, in which the above-mentioned feeding case (
A feeding disk (20) is provided with an appropriate gap to the semicircular inner circumferential surface of 7), and the seed is placed on the outer circumferential surface of the feeding disk (20) with the long diameter side of the seed along the outer periphery. An appropriate number of notches (21) into which about half of the parts can be loosely fitted are provided, and this notch 2
1) A groove (2X5) with a semicircular bottom is provided at the front end in the rotational direction, and this groove (2X5) has a support part that is elastically biased and supported against the groove. A holder made of a plate-like elastic body capable of holding the seeds from the outside of the notch (21) is provided, and a drop port (21) is provided from the aforementioned supply port (3) to the drop port (21).
