Description

[Detailed Description of the Invention] The present invention allows seeds to be separated into multiple rows by a two-stage separation and feeding action, and then to be invaginated into a trench position in the soil with air flow. Concerning the method of evenly distributing seeds in a flooded direct sowing machine.

First, the applicant used an air stream to inject seeds with an oxygen supplement attached to them into the trenches in flooded soil to cause invagination sowing.
We have developed a flooded direct sowing machine that promotes good germination and growth by covering the seeds with soil without causing the floating plate phenomenon.

The above-mentioned direct sowing work is normally carried out simultaneously over multiple rows as the moving foundation machine advances, so after separating the seeds into equal amounts, the seeds are air-filled through multiple sowing guide crabs. Uniform germination and growth cannot be achieved unless the seeds are sown in the flow.

However, in the case of a harbor water direct sowing machine that sows seeds inward using air flow, the seeds stored in the seed hopper are separated and supplied to multiple seed conduits in one separation action, and then air is released into the flooded soil. Since the seeds are only sown invaginated by the flow, when the number of sowing rows is six or more, six or more long seeding conduits are also required.

By the way, if the number of sowing conduits is increased in proportion to the number of sowing rows, the entire separation bag will be large and tall, and the structure will be complicated and heavy, which will affect the straight line performance and maneuverability of the aircraft. To make matters worse, the large number of seed conduits becomes complicated and makes assembly work impossible. As a result, according to the previous configuration, there was a momme point where the number of sowing rows was regulated to a small number. In view of the foregoing, the present invention has been developed by scooping up the seeds provided in the bare chamber with a uniform liner roll, and then separately inserting the seeds into the ventilation chambers that are equally divided in the ventilation barrel. The air is supplied to the seed conduit provided on the discharge side of the ventilation chamber, and the other end of each of the barrel conduits is connected to a proportioning body having a separating cone erected in the center to flow inside the seed conduit. Seeds carried by the air flow are allowed to fall into even numbered feeding chambers divided equally around the separation cone, and at the same time are connected to falling chambers in symmetrical orientation in the form of a skin. While separating the seeds evenly from the sowing tube, the seeds are sown by air flow into the fertilized soil of the groove formed by the groove cutting blade attached to the back side of the leveling sowing body, thereby causing the seeds to be sown twice. An attempt is made to provide a seed equalization feed device for a flooded direct sowing machine that can form a large number of sowing rows even with a small number of seed conduits through a separate feed action carried out over stages, By using a bag pupil with such a configuration, the configuration of the uniformly distributed bag pupil can be made simple and lightweight to improve the straightness and stability of the aircraft, and it is also possible to achieve uniform germination by separating the seeds into equal amounts. Can be done.

Next, the configuration of a flooded direct sowing machine equipped with the device of the present invention will be described with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a movable pus machine equipped with a prime mover 2, a pair of left and right running wheels 3, 3, a handle 4, etc., and a rear machine stand la of the above-mentioned movable pus machine 1 is used to distribute seeds evenly into a plurality of seed conduits. An upper separation supply V-supply plate 5 is removably mounted, which separates the quantity and conveys it by air flow.

As shown in detail in FIG. 3, the structure of the device 5 is as shown in detail in FIG. A feed roll 8 having a plurality of exposed strip grooves 9 extending in the longitudinal direction is rotatably housed in a storage shaft, and a feed amount that can be raised and lowered is placed at a critical position between the feed chamber 6 and the seed hopper 7. The adjustment plate 10 is inserted into the wire outlet 11 which is connected to the lower part of the feed chamber 6, and the inside thereof is divided into an even ventilation chamber 14 by a plurality of vertical partition plates 13.
The air blowing chambers 14 are connected to the air blowing cylinders 12 which are respectively partitioned as shown in FIG. 4 will be provided. A blower 16 is provided on the base end side of the blower cylinder 12.
is connected. Therefore, the seeds are separated into equal amounts into the plurality of seed conduits 15 by the above-mentioned separating and feeding device 5, and are conveyed by the air flow. As mentioned above, the other end of each of the seed conduits 15, which are provided in a plurality of branched shapes, is molded into a hollow shape to have a bulging tip shape that gives floating properties. They are each connected to a lower separation supply/field combination device 18 installed on a Kohei-type leveling seeding body 17 consisting of a plurality of pieces.
A plurality of the above-mentioned leveling sowing bodies 17 are removably attached to the rear machine base la at approximately equal intervals via attachment members 19, and in addition, one leveling sowing body 17 has one on the back surface when viewed from the plane. A plurality of groove cutting blades 20 having a V-shape are attached.
In a beautiful embodiment of the present invention, two bookkeeping blades 201 are installed. The lower stage separating and supplying machine 18 that has been completed has a conical or pyramid-shaped cone 2 at the center of the bottom inside the equalizing main body 21 which has a cylindrical shape as a whole.
2 is erected, and around the cone 22 there is a partition wall 23...
......' are set up at equal intervals to provide an even number of inlet chambers 24, and an even number of symmetrical light inlet chambers 24 are provided in an even number. Connects one end of the two branched seeding tubes 25, respectively. Therefore, when four feeding chambers 24 are provided, there are two seeding tubes 25, and when there are six feeding chambers 24, there are three seeding tubes 25. The end of each seeding pipe 25 connected as described above is inserted into the inside of the above-mentioned cropping blade 20. Accordingly, the plurality of seed conduits 15 separated from the lower separation supply V-feeding device 18' are further separated into a larger number of seed conduits. In addition, the above-mentioned equal portion main body 21
If necessary, a funnel 26 is provided above the cone 22 erected within the cone 22 to drop the seeds conveyed into the equalizer body 21 via the seed conduit 15 to the center of the cone 22. This allows for a more uniform separation effect.

Further, the equalizing main body 21 can be divided into two parts.
Next, the operation of the present invention will be explained. Now, an oxygen supplement, such as Ca0
After storing a large amount of seeds to which No. 2 was attached, the bare seeding amount adjusting plate 10 was raised appropriately, and the mobile agricultural machine 1 was allowed to sow seeds. Roll 8 and blower 16 are rotated.

Then, the seeds introduced into the line drawing chamber 6 from the seed hopper 7 enter the bare groove 9 recessed in the circumferential surface of the rotating feed roll 8, and are uniformly distributed from the line drawing port 11. The air is dropped into respective ventilation chambers 14 partitioned inside the ventilation arm 12 located directly below. However, since the air flow created by the blower 16 is flowing in each of the ventilation chambers 14, the air is separated from the air outlet 11 in equal amounts and the air is distributed in each of the ventilation chambers 1.
4. The seeds separated and dropped into the chambers are conveyed through the respective seed conduits 15 to the lower separation supply bag hawk 18 by the turbulent action of the air current, and are equally distributed. It is introduced into the main body 21. However, since a cone 22 is erected in the center of the equalizing body 21, the introduced seeds are evenly separated by the separating action of the cone 22 and enter the evenly divided nourishment chambers 24. After that, the Shigiri chamber 2 was set up at each target position.
4. The seeds in the merging state are passed through the two seeding pipes 25, 25, and the flooded soil surface is leveled by the leveling sowing body 17 that advances with the moving foundation machine 1. However, it is vigorously sprayed into the trench position made by the cutting blade 20, and after invading the soil, it is covered with soil to an appropriate thickness.Therefore, when you want to set the number of sowing rows to 8, In the embodiment of the present invention, if four seed conduits 15 are provided, the latter are divided into two by the lower separation/supply device 18, resulting in eight lines.
Therefore, the desired number of sowing rows can be easily obtained by increasing or decreasing the number of seed conduits 15 and the number of feeding chambers 24. In short, the device of the present invention has the above-mentioned specific configuration, so that:
The seeds stored in the stripping chamber 6 are scooped up in equal amounts by the rotating action of the stripping roll 8 and separated and distributed to each equally divided ventilation chamber 14. , Seed conduit 15 in which a plurality of seeds are provided can carry out the first-stage separation stage operation in which the seeds are transported by air flow.

■ After the seeds are conveyed by air flow through the plurality of seed conduits 15 and introduced into the equalizing body 21, they are evenly separated by the cone 22 installed in the center of the equalizing body 21, and are separated into even numbers. At the same time, the seeds are dropped into the dropping chamber 24 at the target position into the dropping chamber 24, which is divided into equal parts as shown in FIG. After a two-stage separation stage operation, the seeds can be sown by airflow into the flooded soil where grooves have been made by a plurality of groove cutting blades 20' provided on the back side of the leveling seeding body.

(2) Therefore, by performing the first separation and supply operation and the second separation and supply operation, it is possible to easily perform the sowing operation over a large number of rows without increasing the number of seed conduits 15. ■
Therefore, it may be possible to improve the straightness and stability of the machine by making the overall structure of the distribution shed device simpler and lighter. It is possible to use a container with a large diameter, and as a result, the sowing operation can be carried out continuously without being clogged with seeds being transported.
