Description

[Detailed explanation of the idea] TECHNICAL FIELD The present invention relates to a drug dispensing device in a seed seeding machine.

In other words, in a seeding machine in which a seeding device having a groove-making body at the bottom is mounted on a traveling machine body so that it can move up and down to adapt to the unevenness of the ground, the seeding device is installed on a traveling machine body so that it can move up and down to adapt to the unevenness of the ground. In addition to having a drug dispensing configuration that allows the drug to flow out to the groove forming body side, the drug dispensing pipe for the drug outflow can be easily connected to the groove forming body side, and swings with the groove forming body side that moves up and down to ensure smooth outflow. This allows the pipe to swing without any unreasonable load being applied to it.

Next, the embodiment shown in the drawings will be described.

Fig. 1 is a schematic side view of the seeding machine, in which wide drum-shaped suppression running wheels 6 are mounted on both sides of a mission case 5 at the rear of the machine, and an engine 1 is mounted above the mission case 5.
A running body is constructed by mounting a handle 8 to the rear, and installing a gauge wheel 10 at the forefront of a frame 9 extending forward.

Behind the gauge wheel 10, four seeding devices B are installed in parallel at intervals in the lateral direction, and each device B is provided with a feed roll 11 at the bottom of a hopper b, similar to the conventional structure, and The hopper b is attached to the support frame 12 which extends in the transverse direction at the front part by means of a parallel support rod 13 so as to be movable up and down by interposing a bullet, and the roll 11 is provided to be rotationally driven by a ground rotary wheel 14. A groove-making body 1 is fixedly installed at the lower part of a guide plate 15 fixed to the lower front part of the hopper b, and behind the groove-making body 1, earthwork bodies on both sides are connected via support rods 16. 17.17 are provided and configured respectively.

In addition, a support rod 18 extending laterally is fixed to the rear upper part of the seeding device B, and a medicine dispensing device A is arranged on the left and right sides from the center of the machine. A drug feeding part a is provided, and an opening/closing pin 21 in the hopper 19 operates to extend or separate from the upper opening of a feeding barrel 20 connected below the feeding part a, thereby feeding out the drug in the hopper 19. The cam body 23 rotates and contacts an operating mechanism 22 that operates the opening/closing pin 21 to operate intermittently, and a pulley 25 is fixed to the rotating shaft 24 of the cam body 23. A belt 27 is wound around the pulley 25 from a pulley 26 fixed to the axle 6 of the running wheel 6, and each hopper 19 is provided with two of the feed pipes 20.

The upper part of the upper pipe 2 is fitted into the lower part of the feeding cylinder 20, and the upper part of the drug dispensing pipe 3 is deeply fitted into the lower part of the upper pipe 2 extending downward so as to be slidable from the outside. , the end of the support band 2B wrapped around the upper part of the drug application pipe 3 is fixed to the rear surface of the hopper b via a bolt 29, and the lower part of the drug application pipe 3 is suspended on the rear side of the groove forming body 1. Then, the spring rod C is inserted into the horizontal small hole 30 formed in the lower part of the drug application pipe 3, and the spring rod C is removably engaged with the engaging body 4 provided at the rear of the groove forming body 1. However, the upper pipe 2 and the drug application pipe 3 are made of resin and are formed with different hardnesses.

Further, both ends of the spring rod C inserted into the small hole 30 are formed into hook portions 31.31, and the engaging body 4 is formed by pins 4a, 4a protruding from both sides of the rear part of the groove forming body 1. 4
A head 32 is formed on the pin 4b, and a stopper 33 is formed on the pin 4b.

Therefore, when connecting the drug application pipe 3 to the groove forming body 1, the hook portions 31 and 31 of the spring rod C are connected to the pin 4 of the engaging body 4.
A and 4b can be connected by engaging with each other in a hook-like manner.

When the machine is moved forward by the rotation of the shelter running wheel 6, the groove-forming body 1 forms a groove, and the ground-contact rotary wheel 14 forcibly rotates the feed-out roll 11 while rotating on the ground, and the feed-out roll 11 is fed out from inside the hopper b. The seeds are guided by the guide plate 15, fall downward, and are directly sown at the rear of the groove cutting body 1, and the soil covering bodies 17 and 17 following behind them cover the sowing trace with soil.

At the same time, the cam body 23 is rotated forward by the suppression running wheel 6.
While rotating, the operating mechanism 22 is intermittently operated, and as a result of this operation, the opening/closing pin 21 moves into and away from the upper opening of the feeding barrel 20 and repeats the process.
The drug is intermittently delivered into the upper pipe 2.
The drug flows from inside to the inside of the drug application pipe 3, and from its lower end to the groove forming body 1.
The seeds are dropped behind the plant, and the seeds are sown and the medicine is applied.

In that case, the parallel support rods 13 may be adapted to the uneven surface of the field.
The seeding device B moves up and down due to the support of the seeding device B, but as shown in FIG. 2 and the drug application pipe 3 slide at the fitting part, and the pipe does not bend and obstruct the flow of the drug, and the upper pipe 2 moves in a piston-like manner, rather promoting the flow of the drug without stagnation. be able to.

Also, due to the engagement between the spring rod C and the engaging body 4, the drug application pipe 3
is elastically supported on the side of the groove-forming body 1, and does not bend due to vertical movement, but rather is swung to promote the outflow of the drug.

As described above, the present invention provides a seeding machine in which a seeding device B having a groove-making body 1 at the bottom is mounted on a traveling machine body so that it can move up and down to adapt to the unevenness of the ground, and the seeding device B is mounted and fixed on the traveling machine body. A spring rod C is engaged with the lower end of the drug dispensing pipe 3 that communicates with the drug dispensing part a side of the drug dispensing device A, and an engaging body 4 is provided in the part of the groove member 1 that moves the spring rod C up and down. Because it is removably engaged in a hook type, even if the groove forming body 1 moves up and down to adapt to the unevenness of the ground, the application pipe 3 remains in the groove due to the engagement between the spring rod C and the engaging body 4. It is resiliently supported on the side of the body 1 to reliably maintain the connection, and it can also be swung to make the drug flow in the pipe smoother, and the medicine pipe 3 can be elastically supported without bending. 3 to the groove forming body 1 side, it has the feature that it can be easily connected by a hook type.
