Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seed charging device for seedling growing cylinders, which charges beet seeds and the like into seedling cylinders that are continuous in a honeycomb shape, for example.

In recent years, when growing beet seedlings, as shown in Fig. 1 with some parts omitted, a plate-like material is used in which a large number of seedling tubes are formed in succession in a honeycomb shape. Using a soil filling machine or the like, fill each of the seedling-growing cylinders (Ro, B) of the plate-shaped material (A) with a specified fertilizer-containing soil, place one seed at a time on top of the soil, and cover with a thin layer of soil.
All of the seedling tubes (Ro, B) have an upward opening shape and a square hole shape.

As mentioned above, the work of loading seeds one by one into a large number of seedling cylinders has traditionally been done manually, which has been extremely inefficient.

In the present invention, a large number of seedlings are continuously formed in a mechanical
It provides a device to charge seeds efficiently.
In addition to being able to freely rotate through an upward slope area and a reversal section that reverses horizontally from a downward slope area,
A seed loading mechanism equipped with a seed loading belt having a large number of aligned seed storage bottomed holes on the surface is mounted on a machine base, and a plate-like material having a number of continuous seedling tubes formed in a honeycomb shape, etc. The seed loading mechanism is arranged at a predetermined position above the moving path of the movable body to be placed, and the seed loading belt is rotated in conjunction with the movement of the movable body, so that the seed loading belt is rotated. When passing through the ascending slope area, the seeds in the bottomless seed boxes with which the surface of the seed charging belt comes into sliding contact are received into the seed storage holes, and then the seeds are placed in each seed storage hole. When the seeds are turned horizontally from the downward slope area, they are sequentially charged into the seedling raising cylinder.

An embodiment of the apparatus of the present invention will be described with reference to the drawings. FIG. 2 shows a partially cutaway side view, and FIG. Attachment parts 2, 2 erected on both sides near the left end
A seed charging mechanism 3 is disposed at.

This seed loading mechanism 3 has horizontal support shafts 4, 5, and 6 at the front lower part, rear lower part, and upper part approximately in the center of the front and back, respectively, and both ends of these support shafts 4, 5, and 6 are attached. The drums 7, 8, 9 are fixed to the respective support shafts 4, 5, 6, and these drums 7, 8, 9 are used for endless seed charging. It supports the belt 10. in this case,
The area between the drums 7 and 8 forms an upward slope area U of the seed charging belt 10, and the area between the drums 8 and 9 forms a downward slope area P.
The drum 9 has a seed charging belt 1.
A reversal portion Q is formed which is horizontally reversed from the descending slope region P of 0, and as shown in the front view in FIG. 4 and in the enlarged sectional view taken from FIG. A predetermined number of beads 11, 11 at a predetermined interval
...is formed.

As shown in an enlarged perspective view in FIG. 6 and in a partial enlarged longitudinal cross-sectional view in FIG. A large number of seed-accommodating bottomed holes 12 with an arrangement corresponding to
These seed-accommodating bottomed holes 12 are formed in a size and depth such that, for example, one beet seed can enter therein, but two beet seeds cannot enter therein.

Next, the support member 1 provided across the attachment parts 2, 2
A bottomless seed box 14 is fixed to 3. This seed box 1
4 consists of side plates 15, 15 and a rear back plate 16, and faces the upward slope area U of the seed charging belt 10, and when the seed charging belt 10 passes through the upward slope area U, the bottomless Many seeds 1 in the seed box 14
Seeds 17 are received one by one into the seed-accommodating bottomed hole 12, and when the seed 17 is horizontally inverted in the inversion section Q, the seeds 17 are allowed to fall. Also, when passing through the reversing part Q, the seeds 1 from the seed storage hole 12
A guide cover 18 whose both ends are supported by the attachment parts 2, 2 is provided along the reversal part Q of the seed charging belt 10 so as to guide the fall of the seeds. Each row of seed storage bottomed holes 12 arranged on the left and right faces a position that opens when facing directly below.

Note that the seed charging belt 10, which is stretched over the drums 7, 8, and 9 which rotate simultaneously with the spindle 6 as the driving axis, is supported with a relatively large tension, but the drum 9 of the reversing section Q is supported by a relatively large tension. The beads 11, 11, . ing.

A gear 20 incorporating a one-way clutch 19 into the protruding end 6a of the support shaft 6 protruding from the mounting portion 2 on one side

Next, running rails 21, 21 extending in the longitudinal direction pass through the insides of the attachment parts 2, 2 on the upper surface of the machine base 1.
are fixed on both sides of the machine base 1, and these traveling rails 2
A cart 23 having main wheels 22, 22, . . . that rolls on wheels 1, 21 is provided. This trolley 23 is configured to have a plurality of continuous honeycomb-shaped seedling cylinders R and B, and can be set to place a plate-like material filled with soil through holding members 24, 24, and is manually operated along the traveling rails 21, 21. A gripping rod portion 25 is provided at the right end of the trolley 23 to enable free reciprocation.

A rack 27 is attached to one side of the truck 23 via a support member 26, and this rack 27 is horizontal along the side of the truck 23, and as shown in FIG. A pinion 3 fixed to the inner end of a rotating shaft 29 supported by a bearing 28 fixed to the pinion 2
0 and the rack 27 can be freely engaged with each other.

The rotating shaft 29 has a pinion 30 fixed to its inner end.
A gear 31 is fixed to the outer end of the gear transmission mechanism 3, and the gear 31 and the gear 20 attached to the support shaft 6 are connected to the gear transmission mechanism 3.
It is possible to interlock freely via 2. In this case, the relationship between the seed charging belt 10 rotating via the rack 27, pinion 30, gear transmission mechanism 32, gear 20, spindle 6, and drum 9 and the movement of the plate material set on the trolley 23 is explained. Operation and relative position settings are easy 2

The two rows are formed to match.

Since the present invention is constructed as described above, as shown in FIG.
2, one seed 17 placed in the seed box 14 is placed in each.

The cart 23 is positioned at the backward end, and the plate-shaped material A filled with soil is placed on the cart 23, and the holding member 2 is placed on the cart 23.

In addition, a guide cover 18 is made to face the reversing part Q of the seed charging belt 10, and the seeds 17 are arranged to fall from the tip edge 18a of the guide cover 18, so that the seeds 17 can be inserted into the seedling cylinder. ensure that

After loading the seeds 17 into each of the seedling cylinders RO and RO as described above, the plate-like material A is removed,
After placing a new plate-shaped material A on the cart 23, the above operation is reversed and the seeds 17 are loaded into each of the seedling tubes R, B, etc. of the plate-shaped material A.

As is clear from the above explanation, by moving the cart, the device of the present invention can automatically put seeds into each seedling tube of the plate on the cart.
In particular, in an upward slope area, seeds are received from the bottomless seed box into the seed storage hole of the seed charging belt, so that the seeds are caught between the seed charging belt and the lower end of the seed box. Seeds can be taken out safely and reliably without fear, and furthermore, the seeds are dropped at a position where the leading edge of the guide cover of the reversing section passes, and the seeds are loaded through the rack, pinion and gear train while moving the cart. Since it is linked to the rotation of the seedling belt, it has many effects such as being able to automatically and efficiently put seeds into a large number of consecutive seedling growing tubes.
