Description

Seed-supplying device for a sowing machine}

The present invention relates to a planter, and more particularly, to a seed supply mechanism of the planter that can improve the reliability and durability of the work of planting various kinds of seeds using its own rotational force without having a separate drive mechanism. .

The use of planters, which can rely on machines for four operations of digging, seeding, covering and pressing soil in rural areas where labor is becoming increasingly scarce these days, is becoming more common. This can be ensured so that seeding can be carried out at a constant depth by adjusting the settings appropriately, the seed supply can be stabilized, and even cover by spring force is ensured.

In addition, compared to hand sowing, the amount of seed sowing is reduced to less than half, resulting in a reduction in the amount of harvesting work, which in turn leads to a reduction in labor costs. In addition, due to the spacing of the seedlings at regular intervals, the ventilation is good, the growth is high, and the quality is equal, so the yield is increased by 20% than the hand sowing.

In addition, by precisely processing multiple grooves in one sowing roll, it is possible to sow various leafy vegetables, seedling seeds, rice seed, soybean, corn, etc. in desired quantity. It is possible to select various planting distances by gear shifting which is a multi-group, and it is possible to sow at arbitrary line intervals by moving left and right.

However, considering the difficult rural economy, it is necessary to exclude the various functions, and to have a structure that can improve work efficiency and durability while having low purchase and management costs. For example, the form of mounting a drive mechanism such as a DC motor or an engine or employing the above-described transmission gear to reduce labor is particularly unsuitable for small farmers.

Accordingly, an object of the present invention is to provide a seed supply mechanism of a seeding plant which can improve the reliability and durability of the work of planting various kinds of seeds using its own rotational force without having a separate driving mechanism.

Accordingly, the fixed shaft 40, the driving plate 20, the fixed disk 10 is integrally coupled and does not rotate. Reference numeral 14 is a handle for operating the seed drill and is coupled to the stationary disk 10 and the fixed shaft 40 which do not rotate, not the rotary cylinder 30.

The present invention is rotatably fixed to the fixed shaft 40 in a state in which the rotating cylinder 30 having a plurality of seeding holes 32 to open only when reaching the bottom to receive the fixed disk 10 in the open surface Is mounted. The rotary cylinder 30 is cylindrical with one side open and is provided with a predetermined (eg eight) seeding holes 32 on the outer circumferential surface.

Further, according to the present invention, a guide cylinder 60 having a plurality of hemisphere grooves 60a for receiving seeds on its surface is rotatably mounted to the output end 22b in the gear train 22 of the power plate 20. do. The guide cylinder 60 is formed of synthetic resin and has the same number of hemisphere grooves 60a as the seeding holes 32 on the outer circumferential surface thereof. Guide cylinder 60 is coupled to receive power from the output end 22b of the gear train 22, it is also easy to remove the structure because it is mounted with a bolt. The driving of the guide cylinder 60 through the gear train 22 refers to FIG. 3 to be described later.

In addition, according to the present invention, the guide 50 for guiding the seed falling from the guide cylinder 60 to the lower seeding hole 32 is mounted in the rotary cylinder 30 so as to correspond to the respective seeding holes 32. The guide 50 has a shape in which the same number of square cylinders as the seeding holes 32 are integrally formed on the circular band. The square barrel of the guide 50 is all open to guide the seed to the seeding hole (32).

1 and 2, the seeding hole 32 of the rolling plate 20 of the present invention is provided with a movable plate 36 which is supported by a hinge with a roller 38 at the top, the roller 38 The movable plate 36 is opened only when the rail passes through the annular rail 24.

In particular, in Fig. 2, the seeding hole 32 is a plate formed in the form of a pyramid, and the movable plate 36 on one side is mounted to be opened and closed via a hinge and has a roller 38 at the upper end thereof. A spring 39 is attached to the hinge portion to keep the movable plate 36 in a normal cloth state.

As such, the seeding tool 32 having the roller 38 rotates together with the rotary cylinder 30, while the roller 38 on one side passes through the annular rail 24 fixed to the lower portion of the rolling plate 20. The movable plate 36 is opened and closed once.

In FIG. 3, the input end 22a of the gear train 22 meshes with the drive gear 34 on the rotary cylinder 30 at the rear surface of the driving plate 20 to rotate. The rotation cylinder 30 is fixed to the drive gear 34 concentric with the rotation axis. The input end 22a of the gear train 22 meshing with the drive gear 34 passes through the driving plate 20 and rotates integrally with the first gear of the gear train 22. At this time, the drive gear 34 of the rotary cylinder 30 and the last gear of the gear train 22, that is, the output end 22b should be rotated at a 1: 1 rotation ratio in exactly the same direction.

In FIG. 4, the guide tube 60 according to the present invention has a curved plate 62 which prevents the seed from falling until the seed reaching the hemisphere groove 60a on one side from the hopper 12 rotates to the opposite side and falls. It is further provided. The conduit of the hopper 12 reaches the hemisphere groove (60a) of one side and when the seed (S) is accommodated, the seed (S) falls at a point rotated 180 ° in that state. In the meantime, the arc-shaped curved plate 62 is installed so that the seeds do not leave the hemisphere groove 60a arbitrarily.

5 is a block diagram showing an example of using a planter according to the present invention, looks at the operation according to the present invention with reference to FIGS.

In Figure 5, the planter of the present invention has a method of using only the main body consisting of a fixed disk 10 and the rotating cylinder 30, and a method of using the additional wheel as shown in the reference numeral 18 through the frame 16. In the former case, since the seeding machine is light in weight, the operation is convenient, while in the slope, the operation is inconvenient and easily overturned. In the latter case, the rolling resistance must be overcome in the details of friction with the ground, which requires a considerable amount of maneuverability, but stable operation is possible.

In any of the above cases, when the seed drill is driven while pushing the handle 14, the rotary cylinder 30 is rotated together with the drive gear 34 to rotate the gear train 22, and eventually the guide cylinder 60 is rotated. When the seeding opening 32 on one side reaches the ground during the rotation of the rotary cylinder 30, the movable plate 36 is opened to open as shown in FIG.

At the same time, one seed S falls as shown in FIG. 4 and is seeded through the open seeding hole 32 at the bottom through the guide 50. After seeding is completed, the movable plate 36 is shock-returned so that the soil of the open ground is collapsed again. A shocking return is possible because the annular rail 24 increases in thickness and then suddenly breaks. When the roller 38 of the seeding hole 32 is in contact with the annular rail 24 at the bottom as shown in FIG. 3, the movable plate 36 is opened and the seeding hole 32 is already closed when the upper portion reaches the top.

If the hemispherical groove 60a of the guide tube 60 is replaced with four, the planting distance can be doubled. The size and quantity of the hemisphere groove (60a) can be variously modified depending on the type of seed and can be easily replaced during the work.

Therefore, the present invention is to ensure that the seeding as well as the cover work is done at the same time, and workability improvement to solve the manpower shortage as well as to improve the germination rate.

In addition, since the power of the rotating cylinder 30 is transmitted to the gear train 22 without using a motor, the reliability and durability of the operation are improved. Even if the speed of driving the seed drill changes, the timing of the rotation cylinder 30 and the guide cylinder 60 is exactly the same.

In addition, since the movable plate 36 is connected to one annular rail 24, the structure is simple and manufacturing cost is reduced.

According to the above configuration and operation has the effect that can improve the reliability and durability of the work of sowing a variety of seeds using its own rotational force without having a separate drive mechanism.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
