Description

[Detailed description of the invention] Industrial applications The present invention relates to a seeding conveyor for a seedling nursery.

Conventional technology In a configuration in which a seedling raising device is placed on the top surface of a seeding conveyor and transferred while sowing by a seeding device, a rack is formed at the bottom of the seedling raising device, and a part of the conveyor is equipped with a pinion or a pinion that engages with this rack. A sprocket is provided to ensure feeding of the seedling grower under the seeding device.

Problems to be Solved by the Invention In the seedling raising device of the above type, the sprocket often does not mesh accurately with the rack portion.When the protruding portion of the rack and the protruding portion of the sprocket engage with each other, the sowing position of the seedling raising device is incorrect. There is a risk that the seedling raising device itself may be damaged.

Means for Solving the Problems This invention provides a seedling raising device (1) that rotates by engaging with a rack (3) on the bottom of a seedling growing container (2) that receives the seedling growing device (1) in a sowing position. The seeding conveyor for a seedling nursery is configured such that the feeding speed of a sprocket (4) that feeds the seedlings to a seeding position is higher than the feeding speed of a conveyor belt (5) that carries and transfers the seedling growing receiver (2).

Effects of the Invention During seeding work, the seedling growing device (1) is received by the seedling growing receiver (2), placed on the conveyor belt (5), and transported. When this seedling raising container (1) is transferred to the vicinity of the sowing position by the seeding device, the sprocket (4) is held on the rack (3) on the bottom of the seedling raising container (2). ) together with the seedling raising device (1), and then transported to the sowing position where the seedlings are sown.

The rotation speed of this sprocket (4) is determined by the conveyor belt (
5), so the sprocket (
4) starts to engage with the rack (3), move the seedling-raising container (2) one step in the direction of transfer, and then move the rack (
When the protruding part of the sprocket (3) and the protruding part of the sprocket (4) are in contact with each other, they slip, causing the rack (3) and the sprocket (4) to slip.
4), the seedling-growing receiver (2) can be transferred in the transfer direction by rotating the sprocket (4) in a state in which the protruding portion and the trough portion are engaged with each other.

Effects of the Invention In this way, the speed of the sprocket (4) that meshes with the rack (3) on the bottom of the seedling receiver (2) and sends it is faster than the speed of the conveyor belt (5) that receives and transfers the seedling receiver (2). By increasing the rotational speed, the rack (3) and the sprocket (4) can be accurately and smoothly transferred to the sowing position by engaging and pulling the sprocket (4) in the transfer direction. Accurate sowing can be maintained.

Embodiment In the illustrated example, the l'f seedling container (1) is made of a kneaded molded product such as paper, and forms part of the seedling bed material during seedling raising. Pyramid-shaped seeding pots (6) are formed on the upper surface by arranging them vertically and horizontally, and are provided in a rectangular shape on the plane of incidence. The seedling growing container (2) on which the seedling growing device (1) is placed is box-shaped and has a width and depth that allows the seedling growing device (1) to fit into it. A guide groove (7) is formed along both left and right sides of the guide groove. (8) is a protrusion formed on the inner bottom surface of the seedling growing container (2), which engages with the bottom surface of the seedling growing device (1) to prevent the seedling growing device (1) from moving.

The conveyor has a conveyor belt (5) on the machine base,
It is provided to move while receiving the bottom surface of the seedling-raising container (2), and is driven and rotated by a motor (9). This conveyor belt (5
), a seeding device (10), an above-the-floor feeding device (11), etc. are provided. Sprockets (4) are provided at two locations on the upper and lower sides of the seeding device (10). On the horizontal axis (+2) is the rack (
A sprocket (4) is provided at a position facing the guide groove (7), and a regulation width (13) is provided at the center at a position facing the guide groove (7).
A guide ring (15) made of a rubber roll is provided on both the left and right sides of the roll (forming 10 parts) that can receive the bottom surface of the seedling receptacle (2).The regulation width of this guide ring (15) The part (13) fits into the guide groove (7) of the seedling receiver (2) and rotates to move the seedling receiver (2) straight in the transfer direction.These front and rear shafts (12) are connected to the motor ( 9), and is provided to rotate in the same direction at a slightly higher speed than the conveyor belt (5). (i
o) is the sprocket shaft that is transmitted from the motor (9),
From this, the conveyor belt (5), sprocket (4) shaft (12), etc. are driven and rotated by the check 7 (17) (1a).

The seeding device (lO) includes a hopper (19) that accommodates seeds.
A feed-out roll (20) is provided at the door portion of the seedling raising device (20), and this feed-out roll (20) is configured to be driven by the sprocket (4) M (12) and the chevron 7 (21), etc., to feed out the seeds. 1) This feeding roll (10), which is used for sowing seeds, may be of a spot-seeding type so as to sow seeds according to the form of the seeding pot (6) of the seedling nursery (1).

The floor supply device (11) includes a hopper (2
2) A floor soil delivery belt (23) consisting of a flat belt at the bottom of
A bell) (
24) is provided with a talatch pulley (25), and a switch (26) for detecting the seedling raising device (1) provided on the upper side of this floor feeding device (11) is used to control the talatch pulley (25).
is operated like frLm to turn the transmission on and off, and the seedling raising device (1) can be fed out on the floor only when it is located under the floor feeding device (11). (2
7) is a shaft that is gear-transmitted from the tin rocket shaft (16), and one end of the bell (24) is passed to this shaft (27).

When the seedling growing container (1) is placed on the seedling growing container (2) and placed on the conveyor belt (4), while the Yf bacteria receiving container (2) is being transferred, the regulating ring of the guide wheel (15) (13) is fitted into the guide groove (7) on the bottom to guide the transfer direction of the seedling receiver (2), and the tin rocket (4) is engaged with the front end of the rack (3). .

Since this sprocket (4) is faster than the transfer speed of the seedling receiver (2), it works to engage the rack (3) and pull it forward, and if the sprocket (4) engages the rack (3) and pulls it forward, If the teeth of the sprocket (4) butt against each other and the engagement is incomplete, the sprocket (4) will slip and the next tooth will touch the rack (3) (3).
As a result, the sprocket (4) meshes accurately with the rack (3).

The seedling receiver (2) and the seedling grower (1), which are fed in this way by the rotation of the sprocket (4), are seeding devices!
While passing through the lower part of (10), the feed roll (20)
The seeds are fed out by Seeds are in each M type pot (6)
When this seedling nursery (1) passes under the floor feeding device (11) with the seeds sown at the bottom of the
) is activated, the clutch pulley (25) is activated, and the floor is filled by the rotation of the delivery belt (23).

When sowing and filling on the bed are completed in this manner, a seedling box is fitted onto the seedling container (2) from above, and the seedling container (1) is held between the top and bottom and turned upside down. Seedling container (
2) When removed, the seedling raising device (1) in the seedling raising box will be in a state where the upper part of the bed is located at the bottom and the seed part is located at the upper part.

In this state, cover the top with soil to germinate and raise seedlings.
