Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a foreign matter removal device for a feeding device in a seeding machine, a fertilizer applicator, etc.

<Prior art> As a feeding device in a seeding machine,
As described in Japanese Patent No. 5, it is known that a feed roll is provided on the lower side of the feed case, and the seeds in the reservoir of the feed case are fed out in fixed amounts by the feed roll.

This is because when removing the remaining seeds from the reservoir after sowing, the entire side plate of the reservoir must be removed and the seeds inside must be scraped out, which is cumbersome.

Therefore, it has been proposed to provide a residual quantity outlet and a shutter on the bottom wall of the reservoir 117, open the shutter, and take out the seeds from the residual quantity outlet by allowing them to fall naturally due to their own weight.

<Problems to be Solved by the Invention> In this way, it becomes easy to take out the remaining amount of seeds. However, if the seeds are contaminated with dust or exfoliated powder, these foreign substances cannot be separated from the seeds and removed.
This is the same as that described in Japanese Patent No. 925. If the work is continued with such foreign matter mixed in, it will accumulate on the bottom wall of the reservoir, and the upper seeds will not flow downwards and become stagnant, or the unwinding part of the unwinding roll will become stagnant. It has the disadvantage of clogging. In particular, in the case of a direct sowing machine in flooded soil that uses seeds coated with culver on the outside, removal of peeling powder from the culver becomes a problem.

<Means for Solving the Problems> The present invention solves these problems by providing a delivery roll and a mechanism for removing the remaining amount of the material to be fed out from the bottom wall of the reservoir. In a dispensing device equipped with an outlet, a shutter for opening and closing the outlet, and a metal fitting, the sieve section t-set is as follows so as to pass through the shutter foreign substances such as dust and peeling powder that are smaller than the object to be dispensed.

Function: Since the shutter is equipped with a sieve, if foreign matter such as dust or peeling powder is mixed into the material to be fed out, and if it is smaller than the material to be fed out, it will pass through the entire sieve and accumulate. Can be separated and removed outside.

<Example> Hereinafter, the present invention will be described in detail with regard to the illustrated example.
The figure shows all examples of direct seeding machines in flooded soil, and the Il+ is fully equipped with enogene, etc., and the drive wheels are connected via transmission cases (2) on both sides:
31 are provided. (4) It is a support frame that protrudes rearward from the fuselage +11, and a handle (5) is provided at the rear end through an upwardly curved part. It is arranged on the lower side of the fuselage (1).

(71 is the transmission case, 7 norm (411Ci axis (8)
Supported by The transmission case (7) is provided with a pair of upper and lower tool bars 19+lα extending to the left, and the upper tool bar F91K is connected to the seed tank (1
1), Lower toolbar t101 VC is provided with a pair of seeding floats (the ratio is large).

The seed tank (Satori has a feeding device 03 on the lower side.

As shown in Figure 1, the feeding device aiFi has a seed tank (Il
The feeding case side connected to the lower side of + and the feeding case (1
A rotatable VC is provided at the lower part of the case 41, and a feed-out roll 115It- having an outer periphery i' (a feed-out recess (I81t) is provided, and the seeds lη in the reservoir 061 of the feed-out case round are fed out by the rotation of the feed-out port I and 051). A drive shaft mounted on the transmission case (7) is pushed through the delivery port L1051, and the delivery port 5) is rotationally driven by this drive shaft. A seeding chute (211) is provided below the outlet end of the lower part of the case circle.

Seeding 70-t (121 is the bottom toolbar f10+V
C fixed 71. It is connected to +1 link. A groove G is formed in the sowing 70-toe U21 so as to be recessed from the rear side, and a furrowing device and a soil covering member west are provided in the front and rear corresponding to the notch @, and a groove is provided in the middle thereof. A sowing guide plate connecting the lower ends of the sowing chute 4 is provided in the part.

As shown in FIGS. 1 and 6, the bottom wall nVc of the dispensing case (I4J) is formed with a residual quantity outlet located near the dispensing roll (15), and a residual quantity outlet thereof. A shutter groove 291 is formed on the edge of the shutter groove 281.A shutter edge is inserted into the shutter groove so that it can be freely inserted and removed, and this shutter '301Vc side outlet device can be opened and closed.The shutter '301 is Consisting of members such as iron plates and stick plates, as shown in Figures 4 and 5, the portion VC corresponding to the outlet 21JK allows only foreign matter such as dust and peeling powder smaller than the seeds (17) to pass through. The sieve part 3z of the small hole method is formed as shown in FIG. is structured in a comb-tooth shape. Nine.

The sieve portion 3 of the shutter field is formed in the longitudinal direction along the rotational direction of the feed roll 1151 so as not to interfere with the flow of seeds. Note that '351' is a knob for punching.

In the above configuration, at the time of sowing, the drive shaft rotates the feed roll t15) to feed out the seeds υη in the reservoir portion of the feed case round in fixed quantities, and drop them through the exit a, the sowing chute 12Llt, and the cutting groove. Seeds ση are directly sown in the groove formed in the container (24I) and covered with soil using the soil covering member G.

When the seeds are fed out from the feeding loaf 16), the seeds Oη in the seed tank (11) sequentially flow down into the reservoir portion α■.

On the other hand, if foreign matter 1311 smaller than the seed diameter, such as dust or exfoliated powder, is mixed into the seed mouth, it will be separated by the sieve part '321 at the shutter edge and fall downward as shown in Figure 1, so that it will accumulate. If it accumulates on the bottom side of part a, as in the conventional case, or the feeding recess U311C of the feeding roll (16) gets clogged.
There is no problem and the predetermined feeding performance can be maintained over a long period of time. Il again! sGz fits in from the sleeve l-1331 and the thin rod, and its direction is along the rotational direction of the feed roll (16), tsu'! Since it coincides with the flow direction of the seed σ force, the 1w part '321 does not hinder the flow of the seeds ση or promote peeling of the seeds (culpers, epidermis, etc.).

To remove the remaining amount of the seed (i), if you pull out the shutter head in the direction of the arrow, the seed ση in the pool pupil can be taken out by natural fall.
If there is a seed αη that has been bitten by 3VC, it can be easily removed by tapping the tip side after pulling it out, since the shutter is comb-shaped.

In the above embodiment, the sieve part '32 is made into a slit 133 with one end open, but a continuous part may be left on the tip side as shown in FIG. 6, or a large number of round holes may be made. It may be configured as follows.

Furthermore, as shown in FIG. 7, the shutter field outlet 28
A large hole 3 is formed in the corresponding portion of 1, separate narrow rods are provided at regular intervals in the hole 3η, and small holes (closed) are formed between adjacent narrow rods. In other words, the sieve portion 3z may have any shape as long as it functions as a sieve.

In addition, the VC can be implemented not only in a seeding machine but also in a dispensing device for a fertilizer applicator that dispenses granular fertilizer.

Effects of the Invention> According to the present invention, even if foreign matter such as dust or peeling powder is mixed in the material to be fed out, it can be separated by the sieve part of the shutter and removed to the outside of the collecting part. Accumulation within the unit and clogging of the feeding roll can be completely prevented, and the performance of the feeding device can be maintained over a long period of time. Further, since a shutter VCQ portion t- is provided to open and close the remaining amount outlet, the structure is simple and Vc can be easily removed.
