Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seeding device for a pot seedling box in which a large number of pots are arranged.

[Prior art]

As this type of conventional technology, Utility Model Application No. 114/55-60
As shown in Japanese Patent No. 720, there is a seeding machine in which a rotating brush is provided opposite to a seed feed roll, and a paddy receiving box is detachably provided opposite to the rotating brush.

However, in the above-mentioned conventional technology, the paddy receiving box is provided opposite to the rotating brush, so if the paddy receiving box is full of seeds with stems, etc., the sowing operation is stopped. However, the rice receiving box had to be removed and the accumulated seeds with stems had to be thrown away, resulting in extremely poor work efficiency.

Means for Solving Problem C] This invention solves the problem described in "-". A rotating brush is provided opposite to the upper side of the seed feeding roll, and a receiving gutter is sunk opposite to the rotating brush. A seeding device for seedlings in pots, characterized in that a transfer device is disposed in the receiving gutter, and the receiving gutter receives seeds with branches and stems removed from the seed delivery roll by a rotating flange and discharges them to the outside. That is.

〔Effect of the invention〕

The rotating brush removes excess f・j from the seed roll soil! In addition to removing seeds and stemmed seeds and awns, etc., can be taken out from the seed dispensing roll and disposed of into the receiving trough.The seed delivery of the seed dispensing roll is stabilized, and the seeds and awns, etc. attached in the receiving trough are removed from the outside. Since it can be discharged in a continuous manner, sowing can be carried out continuously and efficiently.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

1 is a transfer conveyor and a transfer bell 1-3 is placed on the top of the seeding table 2.
is wound and rotated by a motor 22.

4 is the receiving box for the 6-piece device. Reference numeral 5 denotes a seedling raising device made of paper or synthetic resin material, and a cone-shaped seedling raising box 1-58 is provided continuously in the left-right direction and in the acid rearing direction.

Reference numeral 6 denotes a seeding device, which is provided above the transfer conveyor 1. To explain this seeding device 6, 7 is a hopper for storing f4j rice, and the seed rice discharge ports 8a and 8b at the lower part are disposed at the front and rear in the transfer direction.

9a, 9b are seed feed rolls for aligning and transporting seed rice, and these are provided with spiral grooves 10a, 10b.
The rear rolls 9a, 9b are provided in a V-shape when viewed from the side, and a sprocket t"lla,
llb is provided and configured to rotate in the same direction, and the discharge [18a] is configured to rotate in the same direction.

The seed rice is discharged from 8b and falls into the spiral groove 1 in the valley of each roll.
They are arranged so that they are transported upward while being aligned at 0a and 10b.

Reference numerals 12a and 12b are rotating brushes that prevent a large number of paddy seeds from being lifted up at once, and also catch the seed paddy seeds and awns with stems on each roll 9a and 9b, and take them out from the rolls and send them to the receiving trough 16a described below. , 16b.

13a, 13a- and 13b, 13b... are seeding cylinders, and the front side seeding cylinders 13a, 13a... are rolls 9a, 9.
The sowing tubes 13b, 13b, . . . on the rear side are located at the upper ends, where the seed rice is transported by the rolls 9b, 9b, . . . .

The seeding tubes 13a and 13b are shifted in the left and right lateral directions by a pinch of the seedling raising bot 5a of the seedling raising device 5 in the lateral force direction.

14a and 14b are suction ducts, and the roll 9a.

9a...lower and roll 9b, receiving hopper 15 below 9b
a, suck the air in 15b, roll spiral 1:'i
'LOa and 10b are designed to suck up waste seeds and garbage that come out from the extraction. In addition, the suction ducts 14a, 1
The suction by 4b ensures that the seed grains supplied to the troughs of the rolls are lifted up in an upright state.

16a and 16b are receiving channels, and the rotating brushes 12a and 1
The rotating brushes 12a, 1 are provided opposite to the rotating brushes 12a, 1
The seed rice with stems, awns, etc. that have been raked up by the roller 2b are received from the brushes 12a and 12b, which roll the same offshore.

Reference numerals L7a and 17b are screw conveyors serving as transfer devices, and are used to transfer the stemmed rice seeds, grains, etc. in the receivers 116a and 16b to the outside and to the side.

18a and 18b are discharge shoes 1-,
1- Competition? + 7XI 17'hL-A raking is for discharging seeds, awns, etc. with six-drawn nine-stemmed seeds to the outside.

In addition, 19 is a covering soil supply device, 20 is a floor supply device, 21 is a bed soil leveling brush, 22 is a transfer belt 3 and a seeding device 6.
This is an electric motor that drives the covering soil supply device 19, the bed soil supply device 20, and the bed soil leveling brush 21.

In the upper configuration, the seedling raising device 5 is placed in the receiving box 4, and while being transferred by the transfer conveyor 1, covering soil is supplied, and then seed rice is sown into each box 1-5a by the sowing machine 6. That is,
The lifting roll 9a in which the seed rice in the hopper 7 is being rotated,
9a, 9a- and 9b, 9b.

9b... When discharged from the discharge ports 8a and 8b into the valleys between them, as shown in FIG. 4, they are sequentially aligned and lifted to the upper end side of the rolls. At this time, the suction ducts 14a, 14b
Receiving hoppers 15a and 15b provided at the lower part of the roll
Since the air inside the container is sucked out, the rice seeds can be reliably transported in an upright position.

Then, the rice seeds lifted by the rolls 9a, 9a, 9a... are discharged into the seeding tube 13a, and the rice seeds are transported by the rolls 9b, 9a, etc.
The rice seeds lifted at b, 9b, etc. are discharged into the seeding cylinder 13b.

Then, from the lower end opening, the seedling raising box 1-5a of the seedling raising device 5,
It is sown within 5a... At this time, the sowing position opening 2
The mouth... and ha, ha... are shifted forward and backward and left and right,
In the front seeding cylinders 13a, i3a..., seeds are sown in one row of seedling pots, and in the rear seeding cylinders 13b, 13b-
..., the seeds will be sown in the rows of seedling pots that were not sown with the front seeding cylinders 13a, 13a.

In particular, since rotating brushes 12a, 12b are provided on each roll 9a...9b..., each roll 9a...9b...
・9b...Excess seeds on top are returned to the tank side,
If there are seeds with stems or awns, they are scraped up with a brush, taken out, and discharged into the receivers m16a and 16b, so that stable seeding work is performed. And received% 16 a, 1
Since screw conveyors 17a and 17b are provided inside 6b, the removed paddy seeds and awns with stems are sequentially discharged to the outside.

Sowing can be done continuously.

In the above embodiment, the opposing rolls 9a...
, 9b, etc., the present invention has been implemented from 1/1 onwards, but there are many other sowings 111! Alternatively, the present invention may be implemented in a seeding device that sows seeds using one roll provided with seeding holes.
