Description

A direct spot seeding apparatus type plunger}

The present invention relates to a diverting device installed in a seed drill to divert rice seeds (or fertilizers) to the ground, and more particularly, to a plunger-type diverting apparatus taking a method of forcibly pushing seeds by a plunger.

The direct sowing machine, which is an agricultural machine that directly sows seeds to the ground without growing seeds, performs leveling work, furrow formation work, seeding work and cover work, etc., while being traction installed at the rear of a travelable passenger vehicle such as a tractor or rice transplanter.

Such a direct digger is equipped with a seeding device. Particularly, the branched seeding device is a device for sowing seeds at predetermined intervals, and two comparative subject inventions corresponding to the present invention are presented below.

First, the natural fall-type branched seeding device disclosed in Comparative Invention 1 is a domestic patent registration No. 10-0454245. As shown in FIG. 1, a plurality of seed storage bins 2 supported on the branched frame Consisting of a plurality of rotary-type branch wave tubes (4) for discharging seeds supplied from the seed storage container (2) through the seed discharge ports (3) intermittently formed on the circumferential surface at regular intervals, the rotary type point wave tube ( As 4) rotates at a predetermined speed, the seeds are discharged at regular intervals through the seed discharge ports 3 formed on the outer circumferential surface of the branch wave tube 4, thereby causing a branch wave.

Next, the natural fall type branched seeding device disclosed in Comparative Invention 2 is a domestic patent registration No. 10-0908149, and as shown in FIG. 2, the seed drill coupling bracket 6 is pivotably coupled to the drive shaft 5 , Seeder frame (7) coupled to the seed drill coupling bracket (6), a hopper (8) fixed to and installed on the seed drill frame (7), a rotary barrel supported to be axially rotatable on one side of the seed drill frame (7) (9) and a cam mechanism (not shown) provided on one side of the rotary cylinder 9, and an opening/closing mechanism (not shown) for opening and closing the seed outlet 10 by the cam mechanism.

However, the above-described comparative inventions 1 and 2 are sown by a rotary point wave mechanism, such as a rotary type point spreader (comparable invention 1) and a rotary cylinder (comparable invention 2). The seed outlet is blocked by the soil of the ground when it comes close to or touches the ground, leading to poor seeding.

Therefore, seeding is carried out by separating the rotary type branching device by a certain distance from the ground. do.

In addition, since the seeds are scattered by the wind in the process of falling to the ground from the rotary shunting device, the loss rate increases, and thus the seeding yield decreases.

In order to compensate for this, the present applicant has proposed a forced discharge type seed or fertilizer shunting device in Registration Patent Publication No. 10-1722415 (Comparative Invention 3). The configuration for this is described in detail in the above publication, and a separate description is omitted.

The above patent has the following problems.

First, since the scraper is buried inside the housing, there is an inconvenience of disassembling the housing when replacing it.

Second, when the seed receiving hole passes through the 11 o'clock direction, there is a problem that the seeds are crushed and damaged between the inner peripheral surface of the housing and the outer peripheral surface of the seed supply wheel. This is because the scraper is a brush type, so it is difficult to completely scrape, so some of it flows between the housing and the seed supply wheel, and in this case, it is damaged by barking between the fixed housing and the rotating seed supply wheel.

Third, since the receiving groove is composed of four holes, the seed supply wheel must be rotated at a high speed to enable shunting at predetermined intervals. In other words, when the seed supply wheel rotates at a low speed, a time difference occurs until the receiving groove at the 3 o'clock position reaches 6 o'clock after the seeds are discharged from the receiving groove at 6 o'clock. Therefore, the seed supply wheel must be rotated relatively quickly. Point waves at appropriate intervals are made. Accordingly, the driving load for rotating the seed supply wheel at high speed increases.

Fourth, as the seeds discharged from the receiving groove toward the ground are scattered by the propagating force or by the wind, the precise point wave is not made.

Invention subject to comparison 1: Patent Registration Publication No. 10-0454245 Invention subject to comparison 2: Patent Registration Publication No. 10-0908149 Invention to be compared 3: Patent Registration Publication No. 10-1722415

Attached Figure 3 is an exploded perspective view of the plunger-type branching device according to the present invention, Figure 4 is an assembly perspective view of the plunger-type branching device according to the present invention.

Referring to these drawings, the plunger-type branching device 100 according to the present invention (hereinafter, abbreviated as'spreading device') includes a housing 200, a seed supply wheel 300, a plunger 400, an advancing and retreating means 500, and Includes a scraper 600. This general structure is the same as Patent Registration No. 10-1722415, which is a patent of the present applicant. However, there is a difference in the detailed configuration. The differences will be understood by the explanation below. However, to help understand the overall configuration, the existing configuration will be described in parallel.

The housing 200 is a case of the present wave device, and is preferably made of a plastic injection product for weight reduction.

The housing 200 is formed by combining the first housing 210 and the second housing 220 in a shape corresponding to each other, and the seed supply wheel in the chamber formed by the first and second housings 210 and 220 300, the plunger 400, the advancing and retreating means 500 and the scraper 600 are built.

A seed inlet 201 is provided in the upper part of the housing 200, and a seed outlet 202 through which seeds are discharged is provided in the lower part. Here, a loading space 203 in which a predetermined amount of seeds introduced through the seed inlet port 201 is loaded and stored is provided below the seed inlet 201. The seeds in the loading space 203 are introduced into the receiving groove (to be described later) formed in the rotating seed supply wheel 300. A detailed description of this will be described later.

The seed supply wheel 300 serves to hold the seeds loaded in the loading space 203 of the housing 200 and discharge them to the seed outlet 202, by a drive shaft S in the housing 200. It is installed to be rotatable, and a plurality of receiving grooves 340 for receiving seeds are formed radially on the circumferential surface.

The seed supply wheel 300 includes a hub 310 coupled to the drive shaft S, an outer ring 320 formed coaxially with the hub on the outside of the hub, and the hub 310 and the outer ring 320 It is arranged radially to connect the between, and the receiving groove 340 is formed in the longitudinal direction, and consists of a plurality of receiving ribs 330 formed with long holes 331 in the longitudinal direction on one or both sides thereof.

Here, the receiving rib 330 is preferably composed of eight.

The reason is that it is a condition that can be configured to the maximum in consideration of the diameter of the seed supply wheel 300 and the volume of the receiving groove 340. In the previous patent filed by the present applicant, since the number of receiving ribs was 4 and the distance between the receiving grooves was relatively far, the seed supply wheel had to be rotated at a relatively high speed to obtain the desired point spacing. In this case, driving load due to high-speed rotation may occur, and furthermore, it may cause a problem of shortening the life of the power supply means and the power transmission part, while the seed supply wheel 300 of the present application is accommodated even if it rotates at a relatively low speed. Since the gaps of the ribs 330 are formed closely, it is possible to obtain a desired point wave gap. Therefore, there is no fear of generating an operating load, and it contributes to extending the life of the power supply means and the power transmission part.

It is preferable that the seed supply wheel 300 is made of a plastic injection product for weight reduction, like the housing 200 described above.

The plunger 400 is inserted into each of the receiving grooves 340 and advances and retreats along the depth direction of the receiving grooves to adjust the contents of the receiving grooves.

Advance and retreat means 500 advances and retreats the plurality of plungers 400, and serves to adjust the degree of advance and retreat for each receiving groove 340, and in particular, a specific receiving groove is located at the top (12 o'clock) In this case, the plunger inside is retracted downward, and when another specific receiving groove is located at the lowest (6 o'clock) position, it plays a role of advancing the inner plunger to the opening of the receiving groove. In addition, when the specific receiving groove is located at the 11 o'clock direction, it also serves to retreat the plunger inside the plunger further downward than the 12 o'clock plunger.

This advance and retreat means 500 includes a guide roller 510, a cam plate 520 and an elastic body 530.

The guide roller 510 is rotatably coupled to both ends of the roller shaft 511 orthogonally penetrating the plunger 400 through the long holes 331 formed in each of the receiving ribs 330. Here, it is preferable to apply a plastic bearing to the guide roller 510 to reduce weight.

The non-rotating cam plate 520 is disposed on one side or both sides of the seed supply wheel 300 in the housing 200, and serves as a rolling plate for the guide roller 510.

The cam plate 520 has a donut shape, and a cam line 521 serving as a rolling plate of the seed supply wheel 300 is formed on an inner circumferential surface thereof. Accordingly, it is possible to control the position of the guide roller 510 that is rolled according to the shape of the cam line 521, so that the forward/retreat position of the plunger 400 in a coupling relationship therewith can be controlled.

Here, one of the important features of the present invention, the cam line 521 is a 12 o'clock area (in order to allow the guide roller 510 passing through the 12 o'clock direction to retreat in the drive shaft (S) direction compared to the previous position ( 521a) has a relatively gentle curvature, and at 11 o'clock in order to further retreat the guide roller 510 passing through the 11 o'clock direction in the direction of the drive shaft (S) compared to the guide roller 510 in the 12 o'clock area. The region 521b has a gentler curvature than that of the 12 o'clock region.

The elastic body 530 serves to elastically push the plunger 400 in the direction of the opening of the receiving groove 340 while intervening between the bottom surface of each receiving groove 340 and each plunger 400 By doing so, the plunger 400 receives an elastic force to flow in the direction of the outer peripheral surface of the seed supply wheel 300.

The scraper 600 serves to scrape and remove the seeds or fertilizers over-accommodated in the uppermost receiving groove so that the contents suitable for the capacity of the receiving groove can be stored.The scraper 600 is the upper side of the housing 200 Doedoe fitted to the mounting portion 204 in the form of a slot provided in, the outer side of the installation portion is opened, the scraper 600 can be detached through this opening, and the opening is opened and closed by the auxiliary cover 630.

Here, the scraper 600 is composed of a brush holder 610 slidingly coupled to the installation portion 204 and a brush 620 contacting the surface of the seed supply wheel 300 while being planted in the brush holder do.

Therefore, when the scraper 600 is exchanged, if only the auxiliary cover 630 is removed without removing the entire housing 200, one side of the installation part 204 is opened, so that the scraper 600 can be removed, Conversely, since it can be installed through this, the scraper 600 can be easily detached.

For reference, since the scraper 600 is in the form of a brush to prevent damage to the surface of the seed supply wheel 300, the wear cycle is fast, so it must be replaced frequently. Therefore, it can be usefully utilized if it has the structure described above.

Meanwhile, the plunger method of the present application may further include a seed discharging member 700 coupled to a lower portion of the housing 200. The seed discharge member 700 includes an adapter 710 pin-coupled to the lower portion of the housing 200 and a seed discharge pipe 720 integrally formed with the adapter and communicating with the seed discharge port 202 of the housing 200. ).

Here, the seed discharge pipe 720 may be easily removed when mud flows into the inside thereof, and a front part of the seed discharge pipe 720 may be opened so that the seed discharge can be visually seen.

On the other hand, the plunger-type branching device of the present application may further include a pressing member 800 that presses the seeded seeds so as to be mounted on the ground while being foldably installed at the rear of the housing 200. The pressing member 800 includes a coupling portion 810 coupled to the rear of the adapter by a pin p coupling the adapter 710 and the housing 200, and a curved pressing plate integrated with the coupling portion ( 820).

The coupling portion 810 has a long hole 811 through which the pin p passes through both sides thereof, and the end of the pressing plate 820 has a thicker thickness compared to other parts in order to secure a pressing force for pressing the seed. Thus, the pressing portion 821 having increased weight may be formed.

Hereinafter, the operation and effect of the present application will be described with reference to FIGS. 5 to 7.

5 is a full cross-sectional view showing the operating state of the plunger-type branching device according to the present invention, Figure 6 is a cross-sectional view showing the main part showing the operating state of the plunger-type branching device according to the present invention, and Figure 7 is the present invention It is a view for explaining the operating state of the pressing member of the plunger type point wave device according to.

When the drive shaft s rotates, the seed supply wheel 300 coupled thereto rotates.

In this process, when the receiving groove 340 located at the top of the seed supply wheel 300 coincides with the seed inlet 201 of the housing 200, the cam line 521 of the cam plate 520 Since the guide roller 510 passing through this pulls down the plunger 400, the plunger retreats toward the bottom surface of the receiving groove 340 to expand the content of the receiving groove.

The expanded receiving groove 340 is filled with seeds introduced through the seed inlet 201, and the receiving groove receiving the seeds rotates counterclockwise in the drawing as shown in FIG. When coinciding with the seed discharge port 202, the plunger 400 in the receiving groove advances to the most end of the opening of the receiving groove 340 by the elastic thrust of the elastic body 530 that elastically supports it.

Therefore, the seed in the receiving groove 340 is forcibly pushed out by the advancing force of the plunger 400, so that even if the receiving groove is blocked by soil, the plunger forcibly pushes the seed, so that there is no sowing defect.

On the other hand, in the process of putting seeds already loaded in the loading space 203 of the housing 200 into the uppermost receiving groove, it may be overaccommodated beyond the opening of the uppermost receiving groove. Since the over-accommodated seeds are cut by the scraper 600 when passing the 12 o'clock direction, after passing through, the appropriate amount is corrected to be received.

Thereafter, when the receiving groove reaches the 11 o'clock direction, the plunger 400 is further retracted toward the bottom surface of the receiving groove 340 by the guide roller 510 according to the shape of the cam line 521, so that the seed is the receiving groove. Let's go deep inside. Accordingly, it is possible to solve the problem that some seeds that have not been scraped by the scraper 600 are crushed and damaged by flowing between the inner circumferential surface of the housing 200 and the outer circumferential surface of the seed supply wheel 300.

On the other hand, in the present invention, since the number of receiving grooves 340 is increased from the existing four to eight, even if the rotational speed of the seed supply wheel 300 is relatively slow, it is possible to jump at predetermined intervals, thereby reducing the driving load. Furthermore, it has the advantage of extending the life by reducing the load even in the driving motor and power transmission device related to operation.

On the other hand, in the present invention, since the seeds are discharged directly under the seed discharge member 700, it is possible to prevent the wave wave, and since a part of the seed discharge pipe 720 is open, mud does not flow into the seed discharge pipe. If possible, it can be easily removed.

In addition, according to the present invention, by pressing the seeds sown by the pressing member 800, it is possible to prevent the seeds from being blown away by the wind, and the germination rate can be increased. In addition, when the pressing member 800 is not in use, as shown in FIG. 7, the pressing member 800 is erected by rotating the pressing plate 820 so that the upper end of the long hole 811 is caught on the pin (P). You can keep the state.

The present embodiment and the accompanying drawings are merely illustrative of some of the technical ideas included in the present invention, and those skilled in the art can easily infer within the scope of the technical ideas included in the specification and drawings of the present invention. It is obvious that all possible modifications and specific embodiments are included in the scope of the technical idea of the present invention.
