Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a fertilizing and seeding machine that can spread or sow fertilizers/chemicals such as powder and granules, and seeds using the same feed roll. be.

(b) Conventional technology In the structure of the feed roll of a fertilizer seeding machine, the technology of equipping multiple feed rolls of the same capacity was developed in the 1970s.
-31471 publication is known as a technique,
Furthermore, the technique described in Japanese Utility Model Publication No. 12807/1983 is known as a technique that enables the feeding roll to feed out fertilizers, seeds, medicines, etc.

(c) Problems that the invention aims to solve This invention uses one feeding device when only fertilizing or sowing, and uses one feeding device when both fertilizing and sowing are carried out. Connect two units,
By meshing the teeth provided on one of the feeding devices with the teeth of the other feeding device, the feeding power can be transmitted.

(d) Means for solving the problem In view of the above points, the present invention is constructed as follows.

The fitting protrusion 4a of the fitting roll 4 is fitted into the feeding recess 5a of the feeding roll 5, and the feeding amount can be adjusted by sliding the fitting protrusion 4a within the feeding recess 5a. At the same time, the feeding roll 5 driven by the drive shaft 7 is provided with teeth 5b, and the roll unit C constituted by these is fitted in the feeding case 56 to constitute the feeding device A. A feeding device B is provided, and the teeth 6b of the feeding roll 6 constituting the roll unit C of the feeding device B are engaged with the teeth 5b of the feeding roll 5. This allows it to be attached and detached at either the front or rear of the plane in the direction of travel.

(e) Embodiments and operations The purpose of the present invention is as described above, and the structure and operations of the present invention will be explained based on the configuration of the embodiment shown in the attached drawings.

Figure 1 is a front view of the fertilizer seeding machine of the present invention when installed in parallel, Figure 2 is a side view of the feeding device, Figure 3 is a front sectional view of the feeding part, Figure 4 is a side sectional view of the same, and Figure 5 is a side view of the feeding device. 6 is a partially sectional front view of a roll unit, and FIG. 7 is a partially sectional front view of a conventional roll unit.

To explain the overall configuration using Figures 1 and 2,
In the fertilization and seeding machine S, a mounting beam 8 is fixed to a hit such as a tractor or a management machine, and a feeding device A is attached to the mounting beam 8 via a seeding frame 58. The sowing frame 58 can be slid from side to side by loosening the fixing device 37, so that the fertilization or sowing position can be adjusted as appropriate. As a guide for the position, a scale 8a is carved on the mounting beam 8 as shown in FIG.

A roller frame 36 is pivotally attached to the lower part of the seeding frame 58 via parallel links 23 and 24, so that the groove cutting disk etc. can follow the irregularities of the field. The roller frame 36
A support punch 54 supporting the groove making disk 10 is provided at the front end.
is erected and rotatably supports two groove-making disks 10 in a V-shape. Further, a shaft 22 is installed horizontally at the front end of the support punch 54, and a scraper 41 is fixedly installed at both ends of the shaft 22, and the scraper 41 also serves to protect the tip of the guide pipe 19.

Then, a soil covering disk 11 is protruded and supported from the side surface of the roller frame behind the trenching disk 10.
A soil covering roller 12 is supported in a protruding manner from the rear end of the roller frame. Therefore, the seeds or fertilizers sown in the trenches made by the trenching disc 10 and the sides of the trenching disc 10 are lightly covered with soil by the soil covering disc 11 as it moves forward, and are crushed by the soil covering roller 12. .

At the rear of the aforementioned feeding device A, a feeding device B is fixed with a one-touch fitting 31, and the hoppers 1 and 2 and feeding devices A and B are also fixed with one-touch fittings 29, 31, and 32, respectively. Also,
There is a rubber bellows 17 at the lower end of the feeding device A.
A guide pipe 19 is fitted through the guide pipe 19.

Next, the configuration of the feeding device A will be explained with reference to FIGS. 3 to 9. A rotating shaft 21 is fitted onto a polygonal drive shaft 7, and one side of the feeding roll 5 has a toothed portion 5b. The other side is provided with feeding recesses 5a for feeding fertilizer etc. at regular intervals on the circumference. Then, the fitting roll 4 that fits into the feeding recess 5a is fitted together with the spring 16 at the rotating shaft 21, and the adjustment dial 3 is screwed onto the rotating shaft 21.
The capacity can be adjusted by rotating the adjustment dial 3. The feeding recess 5a is deeper and larger than the conventional one, so that large seeds, fertilizers, etc. can be used without replacing the feeding roll, and as shown in FIG. 5c is configured in an arc shape, and the feeding recess 5a
The fitting convex portion 4a of the roll 4 that fits into the roller 4 is also configured in an arc shape.

That is, since the end slope portion 5c and the protrusion tip 4a were conventionally cut perpendicularly to the rotating shaft 21 as shown in FIGS. 7 and 9, the distance between the feeding recess 5a and the protrusion tip 4a was When the capacity is reduced by narrowing, seeds etc. get stuck in the feeding recess 5a and become difficult to come out.
Large particles of fertilizer and seeds could not be sown in appropriate amounts. Therefore, by making the end portion arcuate, it is possible to release the liquid even when the feeding recess 5a and the fitting projection 4a are closed.

A roll unit C consisting of the above-mentioned delivery roll 5, roll 4, rotating shaft 21, etc. is fitted into a delivery case 56, and the rotating shaft 21 is pivotally supported by side covers 27 and 28 from both sides. Further, a brush 33 is fixed to the front upper part of the dispensing case 56, and is brought into contact with the circumferential surface of the dispensing roll 5 to prevent unnecessary seeds from being dislodged. A guide funnel 60 is fixed to the lower end of the feeding case 56.

The feeding device B has a structure that is substantially symmetrical to the feeding device A, and the roll unit has the same shape and a recessed portion of the same size. The driving force of the feeding roll 6 is such that the toothed portions 5b and 6b mesh and rotate in the opposite direction to feed out the roll.By turning the adjustment dial, the capacity of the recessed portion 6a can be changed to feed out an arbitrary amount. It is possible.

With this configuration, when the feeding devices are arranged back and forth, fertilizer can be placed in one hopper and seeds can be placed in the other hopper, or vice versa, or chemicals can be placed in one hopper and seeds can be placed in the other hopper. You can put different seeds into the hoppers, vice versa, or put different seeds into two hoppers, and use them depending on the purpose.

In addition, as shown in Fig. 1, fertilizing and seeding devices are arranged in parallel at regular intervals, so that the first fertilizing and sowing device receives fertilizer, the second fertilizing and sowing device receives seeds, and the third fertilizing and sowing device receives chemicals, or , all seeds, or a combination in which different types of chemicals or fertilizers are placed in each hopper can be made, and furthermore, different types of fertilizers, etc. can be placed in the two hoppers at the front and rear. Therefore, by changing the spacing between fertilizing and seeding machines or increasing the number of fertilizing and seeding machines, it is possible to further increase the number of combinations.

(f) Effects of the invention With this configuration, the invention provides the following effects.

First, when using either the fertilizer application device or the seeding device as a single function, only the feeding device A is driven by the drive shaft 7, and when performing both fertilization and seeding, the teeth 5b and 6b By meshing the two, it is possible to drive both the feeding devices from the drive shaft 7, which simplifies power transmission.

Secondly, since it can be attached and detached only by the engagement of the teeth 5b and 6b, it has become easy to remove it when unnecessary.

Thirdly, since the feeding device A and the feeding device B can be constructed as almost the same parts, the cost can be reduced.
