Description

[Detailed description of the invention] (Industrial application field) This invention is used for seeding machines, and in particular, a funnel-shaped receiving gutter is provided below a guide tube hanging vertically at the bottom of a seed tank's feeding device. This invention relates to a seeding device.

(Prior art) In the above-mentioned conventional seeding equipment, the guide tube that is vertically attached to the tank is fixed to the machine body together with the tank, whereas the funnel-shaped receiving gutter is a float that moves up and down to follow the rice field. Since it is fixed to the side, the lower end of the guide tube faces the upper part of the gutter with a gap between it and the gutter.

(Problem that the invention aims to solve) However, when sowing seeds in flooded rice fields, etc., mud is thrown up when the float takes off from and leaves the rice field when moving around the headland, and mud is thrown up when workers walk. Due to this, mud adheres to the outer periphery of the guide tube,
There are defects in which it becomes difficult to see the falling state of the seeds, and in particular, if there is significant adhesion to the inner periphery of the lower end of the guide tube, the fallen seeds may adhere to this and block the guide tube, thereby impairing the uniform fall of the seeds. Furthermore, in order to clean this, the guide tube had to be removed one by one, which was troublesome.

The technical problem with the present invention is that while it does not cause any problem in the vertical movement of the float, muddy soil adheres to the lower end of the guide tube, making it difficult to see the falling state of the seeds or impairing their falling. The purpose is to prevent this from happening and to make it easy to clean.

(Technical means for solving the problem) The seeding device according to the present invention, which was taken to solve the above problems, is as follows.

In a seeding machine in which a funnel-shaped receiving gutter is provided below a guide tube installed vertically at the bottom of a seed tank dispensing device, the guide tube and the receiving gutter are communicated by a conduit made of a transparent body, and the conduit is connected to the guide tube. The device is characterized in that it is externally supported with a gap between the two and is movable up and down.

(Function) When mud adheres to the guide tube during flooding and seeding work, move the conduit up and down to scrape off the adhering mud, and if there is a significant amount of mud adhering to the conduit itself, pull it out backwards and remove it. to clean up.

(Embodiment) To explain one embodiment of the configuration of the present invention shown in the drawings, the one shown is a submerged soil seeding machine, which has an engine 2 mounted on the front of a traveling body 1, and a central part of the seeding machine. Wheels 4 for propulsion of the machine are pivotally supported on both left and right sides of the transmission case 3 so as to be movable up and down via a swing case 5, and behind the wheels 4, a tank 6 for storing seed rice and a sowing seed are interlocked and connected to the transmission case 3. A seeding unit 8 consisting of a drive mechanism 7 etc. is attached,
A control handle 9 is provided at the rear of the seeding section 8, and a central float 10a is provided at the center of the lower part of the machine.
Side floats 10b, 10b are arranged on both sides.

Below the tank 6, a funnel-shaped guide tube 11 made of a transparent material is vertically attached and detachably fixed, and the floats 10a and 10b are each provided with a funnel-shaped receiving gutter 12 corresponding to the guide tube 11. There is a conduit 13 fitted externally on the guide tube 11 between the guide tube 11 and the receiving gutter 12.
is interposed.

A groove piece 14 is provided at the ground contact portion in front of the conduit 13, and
Behind the receiving trough 12, a soil plate 15 and a soil covering plate 16 are arranged for each sowing row (four rows in this embodiment).

The seed rice stored in the tank 6 is sequentially delivered by a predetermined amount by the rotation of a delivery device 17 provided in the tank 6 as the machine moves, and is fed out in a predetermined amount by a guide tube 11, a conduit 13,
After passing through the receiving gutter 12 and falling into the groove in the soil formed by the groove cutting piece 14, the subsequent soil plate 15 and soil covering plate 1
The seeds are sown and covered with soil in sequence at step 6.

The tank 6 is fixed to the traveling body 1 via a horizontal stay 18, and floats 10a, 10
The rear parts of the rollers 10b and 10b are pivotally supported on the running body 1, and the front parts are movable up and down so as to glide over the rice field surface.

At the rear of each of the floats 10a and 10b, a recess 20 is formed which is bifurcated in plan view and open at the rear, as shown in FIG. Formed gutter 12
A base 12a portion of the is attached.

The conduit 13 fitted on the outside of the guide tube 11 is made of a transparent flexible body such as a vinyl pipe with a square or round cross section, and is fitted on the outside of the guide tube 11 with a gap, so that it can move up and down. At the same time, the receiving gutter 12 is configured so that it can be easily attached and detached by utilizing the rear open portion of the receiving gutter 12.

The present invention is configured as described above, and the power of the engine 2 is transmitted from the mission case 3 to the feeding device 17 via the seeding drive mechanism 7.
As the machine moves, the seed rice stored in the tank 6 is fed out from the guide tube 11 in predetermined amounts through the conduit 13 and from the receiving gutter 12 to the groove forming piece 1.
It falls into the groove formed by 4, and the soil plate 15
and covered with soil by a soil covering plate 16. At this time, the floats 10a and 10b move up and down following the unevenness of the rice field, but since the conduit 13 is fitted around the guide tube 11 with a gap, the up and down movement of the floats 10a and 10b is not hindered. Also, there is no problem with the falling of the seed rice.

It was confirmed that mud was attached to the outer periphery of the guide tube 11 due to the scattering of mud that occurred when the floats 10a and 10b landed on and off the rice field during the rotation of the machine, and the scattering of mud due to the walking of the worker, and the rice seeds were dropped. If it becomes difficult to do so, you can move the conduit 13 up and down and scrape off the adhering mud with the upper edge of the conduit 13.
3 If a significant amount of mud adheres to the body, remove it from the receiving gutter 1.
You can take it out using the rear opening part 2 and clean it. At this time, since the conduit 13 is fitted onto the guide tube 11 with a gap, it is extremely easy to attach and detach, and the operation is extremely short compared to the conventional method in which the guide tube is removed from the tank. It can be done. If the conduit 13 is made of a flexible body such as a vinyl pipe, attachment and detachment operations can be made easier.

In addition, in the embodiment of the present invention, the conduit 13 is provided for each guide tube 11, but especially in the case of a walk-behind seeding machine, the conduit 13 may be provided only in two sections in front of the driver's walking position. You may also do so.

(Effect of the invention) In the present invention, the guide cylinder 11 and the receiving gutter 12 are communicated with each other by the conduit 13 which is fitted onto the guide cylinder 11 with a gap, so that there is no problem in vertical movement of the float. However, the mud adhering to the outer periphery of the guide tube 11 can be scraped off simply by sliding the conduit 13 up and down, which makes it easier to see the state of the falling rice seeds. Since mud does not directly adhere to the seed rice and hinder the fall of the seed rice, there is no need to remove the guide tube 11 one by one as in the conventional one, and the conduit 13 can be easily attached and detached. The mud adhering to the conduit 13 can be cleaned very easily.
