Description

[Detailed explanation of the invention] (a) Industrial application field The present invention involves putting a gel-like fluid mixed with seeds of carrots, garland chrysanthemums, Horen grass, etc. into a tank, and transporting the fluid containing the seeds through a conduit connected to the tank. This invention relates to a dispersion device for a fluid seeding machine that discharges fluid from the lower end into the inside of the row claw.

(b) Prior Art Conventionally, there has been a known technology in which a fluid containing seeds is discharged by a squeezing type pump composed of a pump roller and a presser plate, and the lower part of a conduit for guiding the fluid is opened at the rear of the row claw. -ing

For example, Japanese Patent Application Laid-Open No. 117723/1983.

(c) Problems to be solved by the invention However, in the above-mentioned conventional technology, the pump is configured to discharge fluid by pushing the conduit flatly with the pump roller, and as it is, the conduit is pushed by the pump roller. This results in an intermittent discharge state in which the fluid is vigorously discharged at the pump roller, and there is no trace of the fluid being discharged until it is pushed out by the next pump roller.

Therefore, the seeds were not sown continuously in the grooves made by the row claws, but were sown intermittently in a dotted or chain line pattern, making it unusable for crops that required continuous sowing. be.

The present invention solves this problem.

A diffusion plate 36 is opened into the inside of the "∧"-shaped striping claw 12 and is arranged below the opening of the conduit 22 in the striping claw 12 with a low rearward slope.

(E) Embodiment The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

In the fluid seeding machine shown in Figs. 1 and 2, 1
is a rectangular frame, consisting of two side rods 2 separated by a slight interval, and horizontal rods 3, 3 connecting the central front and rear ends of the frame, with a front shaft 4 bearing on the front end.
A drive wheel 5 having a large number of protrusions 6 on its circumferential surface is mounted, and a rear wheel 8 is supported on an arm rod 7 projecting from the rear end and extending slightly backward.

This frame 1 has a handle 9 for changing direction standing vertically at the front center, and a hand lever 10 whose length can be adjusted is obliquely attached to the rear center and is supported by a metal fitting 11.

12 is a cutting claw configured in the shape of "∧", which is connected to the drive shaft 6.
, and suspend it from the center lower part of the frame 1 using the metal fittings 13.The sharp end of the slightly inclined front edge is dug into the ground A to cut a groove of a certain width, and the projecting piece 14 at the upper rear corner is cut. Attach the soil covering plate 15 to the base via the relay piece.

16 is a tank containing a fluid containing seeds, which is fixed to a support rod 17 standing up at the rear end of the frame 1 with an L-shaped mounting plate 18 and a band 19, and is constricted to the same taper on a gently cone-shaped bottom surface 20. funnel 21
Connect this funnel and curve it slightly so that it points forward and downward.

Reference numeral 22 denotes a conduit made of elastic synthetic resin, which is attached to the tip of the funnel 21 and extends forward almost horizontally, curved into an arc at the center of the frame 1, and inserted into the inside of the cutting claw 12 below. .

Reference numeral 23 denotes an operating shaft supported in the center of the frame 1, a chain 25 attached to this and a chain 24 fixed to the boss of the driving wheel 5 are covered with a chain 26 and covered with a case (not shown).

27 is a roller rotating body fixed to the operating shaft 23, and four pins 28 are set on the periphery at equal angles of 90 degrees, and a pump roller 29 is loosely fitted to the pins to rotate the curved part of the conduit 22. Push it inside.

Reference numeral 30 denotes a holding plate curved in an arc shape, which is made to have a length of about 1/4 circumference (90 degrees) of the roller rotating body 27 as shown in FIG. The bent edge 31 of the lower end is overlapped with the mounting piece 32 at the lower center of the frame and fixed with bolts 33, and the flesh of the conduit 22 is made flat against the pump roller 29 of the roller rotating body 27. Install them so that they are spaced apart by the same thickness.

The presser plate 30 is arranged on about 1/4 of the outer periphery of the upper surface of the roller rotating body 27 on the side where the striping claws 12 are arranged, and this part is configured as a stroke-type pump.

34 is a ring fitted to the conduit 22 near the end of the holding plate 30, and is fixed to the mounting piece 32 together with the holding plate 30 via a key-shaped piece 35, and is attached to the roller rotating body 27.
This prevents the conduit from wobbling due to the recoil when the pin 28 leaves the conduit 22.

The main part of the present invention is related to the structure of the striping claw 12 and the diffusion plate 36, and as shown in FIG.
The flat diffuser plate 36 that fits into the striping claw 12 which has been configured in the shape of the strip is placed in an inclined position with the front raised and the rear lowered, and is fitted into the medial part of the striped claw 12, and both side edges 37,
37 is welded to the inner surface of the row claw to fix the diffuser plate,
The lower end of the conduit 22 is directed toward the front of the centerline of the diffuser plate 36.

(F) Function of the invention An example of a fluid seeding machine equipped with the present invention has the above-mentioned configuration, and the function will be explained next.

The operator puts a gel-like fluid mixed with an appropriate amount of seeds into the tank 16, and moves the frame 1 to the right using the hand lever 10.

As the frame advances, the driving wheels 5 bite the protrusions 6 into the ground and rotate reliably, and the cutting claws 12 cut grooves in the ground.

The rotation of the drive wheel 5 is caused by the chain wheels 24 and 25 and the chain 2.
6 to the operating shaft 23, the roller rotating body 27 on the operating shaft slowly rotates in the direction of arrow B in FIG. The pump rollers 29 loosely fitted onto the pins successively abut against the ends of the horizontal portions of the conduit 22.

The pin 28 moves inside the curved part of the conduit 22 as the roller rotating body 27 rotates, and on the outside of this curved part there is an interval equal to the wall thickness of the conduit 22 which is flattened with respect to the roller 29 of the pin wheel. Since the holding plate 30 is nestled, the conduit 22 is squeezed by the pins 28 which successively move inside the curved portion.

The fluid S containing seeds in the tank passes through a funnel 21 from a cone-shaped bottom 20 and reaches a roller rotating body 27.
The interior of the horizontally arranged conduit 22 is filled up to the area where the holding plate 30 is placed.

The pins 28 are arranged at 90° intervals around the periphery of the roller rotating body 27, and the presser plate 30 is arranged around the roller rotating body 27.
7, so one pin 2
8 reaches the starting end of the presser plate 30, the next pin 28
The fluid containing seeds flows into the curved part of the conduit 22 until the pin 28 reaches this position, and the next pin 28 reaches the push plate 3.
0, the first pin 28 reaches the end of the hold-down plate, and a substantially constant amount of seed-containing fluid is sealed in the conduit between the two rollers.

Subsequently, when the first pin 28 leaves the terminal end of the presser plate 30, the conduit 22 restores itself by its own elasticity, and the fluid containing seeds flows down the lower end of the conduit 22 and is intermittently discharged into the inside of the row claw. be done.

When the conduit 22 returns to its original state, it tries to swing due to the reaction, but in this embodiment, the holding plate 30
Since a ring 34 is fitted to the conduit 22 near the end thereof and fixed to the frame 1, the conduit is prevented from swinging, and the fluid containing seeds is discharged from the conduit 22 at a fixed position.

In such a configuration, the present invention has a diffusion plate 3 inside the "∧"-shaped striping claw 12, as shown in FIG.
6 is attached to close the midsection of the conduit 22 so that the seed-containing fluid discharged from the lower end of the conduit 22 flows down on this diffusion plate, and the seed-containing fluid is almost continuously sown on the ground.

It is best to install the diffuser plate 36 at an angle of approximately 30° for the width of the cutting claws that are normally used here.
It has been confirmed through experiments that this slope produces the desired results. Also, it is best for carrots to sow the seed-containing fluid in a substantially continuous thick line.

(g) Effects of the invention Since the invention is constructed as described above, it has the following effects.

The seed-containing fluid S flows from the lower end of the conduit to the cutting claw 12.
is intermittently discharged into the interior of the diffuser plate 36 and once falls in front of the center line of the diffuser plate 36. Next, the fluid S is transferred to the diffusion plate 36
Since the plate is mounted in a backward downward position, the seed-filled fluid that falls in front of the center line flows almost straight down the plate surface.

As mentioned above, the fluid S is intermittently discharged from the lower end of the conduit 22, so if it is dropped directly onto the ground, it will be in the form of an interrupted line.However, by configuring as in the present invention, the seed-containing fluid is discharged from the diffusion plate 32. As it flows down the surface of the plate, it spreads out almost continuously, so the seed-containing fluid that is sown on the ground forms a nearly continuous thick line, so carrots and other seeds can be placed in different conditions. This has the effect of being able to sow seeds.
