Description

planter

The present invention relates to a planter.

In particular, it is possible to perform fertilization and sowing work according to the traveling speed of the tractor, to automatically spray pesticides in connection with sowing work, and to prevent damage to the plowing blade member. It relates to a planter having a.

Rice farming is mainly cultivated by the rice transplanting method, but the direct growing method is widely known by omitting the rice growing process and the rice transplanting process and sowing rice seed directly on the rice paddy where the rice should grow. This direct cultivation method is carried out by a planter.

A planter is a farming machine that is installed to the rear of a vehicle that can be driven such as a tractor, tiller, or rice transplanter, and sows seeds directly on the plantation by the power of the vehicle. And fertilizing, covering the bone, and the like at once.

On the other hand, the general seeding machine is driven so that the seeding unit for seeding and fertilizing seeds and fertilizer receives power from the take-out shaft associated with the engine of the tractor. In this case, there is a problem in that the power of the engine is transmitted as it is, so that seeding and fertilization are made, even when the tractor is stopped.

In addition, it is extremely difficult to maintain a constant engine speed of the tractor, there is also a problem that the seeding and fertilizing amount is irregular when the seeding and fertilization work interlocked with the engine due to the variation of the engine speed.

As a related art, a seeding speed control apparatus of a seeding machine has been disclosed in Korean Utility Model Publication No. 20-1996-0009863 (prior patent 1).

1 and 2, the prior patent 1 has a drive gear 2 and a gear tooth 2a formed at the same interval so that the combine track wheel 1 can be engaged with the drive gear 2; A first transmission chain 3 connected to the first sprocket coupled to the shaft to transmit the rotational force of the driving gear 2, and a first transmission chain 3 connected to the first transmission chain 3 to transmit the rotational force to the intermediate shaft 5; 2 sprocket (4), the third sprocket (6) which is coupled to the front end of the intermediate shaft (5) and rotates together with the second sprocket (4), and is connected to the third sprocket (6) to transfer power The second transmission chain 7 and the second transmission chain 7 is provided on the other side and is composed of a fourth sprocket 9 for transmitting a rotational force from the seed discharging device 8 of the combine track wheel (1) The driving force is transmitted to the seed discharge device 8 of the seed container 8-1.

Although the above-mentioned Patent 1 looks at the contents or the drawings, there are parts that are partially unclear, but it is difficult to understand in detail, but the technical core is the seed discharge device of the combine chain wheel 1 and the seed container 8-1. (8) is interlocked, characterized in that the seeding is made in proportion to the moving speed of the combine without a separate power source.

This prior patent 1 has a configuration to operate the seed discharging device 8 by joining the projection of the track wheel (1) of the combine and the drive gear (2), the track wheel of the drive gear (2) has a gear form from the beginning. Since it is not possible to engage the drive gear 2 in this way, it is not only practically difficult, but even if this is possible, the rotation of the drive gear 2 is difficult because the track wheel 1 and the drive gear 2 are difficult to mesh correctly. The speed is not constant.

Accordingly, the seed discharging device 8 linked with the drive gear 2 is also difficult to expect uniform operation, and the seeding interval is not constant, so that the seeding reliability is also lowered. In conclusion, the prior patent 1 is a technology that is possible only in theory and excludes reality.

On the other hand, Figure 2 shows another conventional planter, in particular a planter equipped with a pesticide sprayer.

However, the above-mentioned prior patent 2 does not clearly describe how the pesticide spreader is driven, so it is difficult to say that it is linked with a straightener in the pesticide spraying operation.

As expected, in the application of pesticides, a pump for pumping pesticides will be employed by the operator either intermittently or continuously by the pump. The former method is cumbersome to operate, the latter method can be a problem that the pesticide is wasted as well as environmental pollution because the pesticide can be sprayed over irrespective of whether or not the operation of the direct drill.

This concludes the description of the seeding speed control device of the first embodiment.

Hereinafter, the seeding speed control device 200 of the second embodiment will be described.

7 is a perspective view of a seeding machine equipped with a seeding speed control device according to a second embodiment of the present invention, and FIG. 8 is a view of FIG. 7 viewed in the A direction, and FIG. 9 is a view of FIG. As seen from the figure, the seeding speed control apparatus according to the second embodiment is in use, and FIG. 10 is a view of FIG. 7 viewed in the direction B, and the seeding speed control apparatus according to the second embodiment is not used.

7 to 10 above, the seeding speed control apparatus 200 of the second embodiment according to the present invention is installed in the seeding machine (S) is configured to mechanically and electronically control the seeding and fertilizing speed according to the running speed of the seeding machine Has

First, with reference to the drawings, the configuration of the seeding machine (S) to which the seeding speed control device 200 of the second embodiment is applied will be described in detail. It is assumed that the configuration of the planter S described below can be applied to the planter S described above.

The planter S includes a plurality of seed barrels 21 and fertilizer barrels 22 which are horizontally arranged while being supported by a frame F forming a skeleton. Hereinafter, it is called the seed and the fertilizer container 20.

In addition, the planter (S) further comprises a plurality of upper discharge unit 30 for discharging the seed and fertilizer accommodated in the seed and fertilizer container 20, respectively.

In addition, the planter (S) further includes an upper drive shaft 40 for driving the upper discharge unit (30). The upper drive shaft 40 is rotated by the power of the drive motor 50 to be described later to operate the upper discharge unit 30 to discharge the seeds and fertilizer from the seed and fertilizer barrel (20).

In addition, the seed drill (S) further includes a drive motor 50 for driving the drive shaft 40 in rotation. The drive motor 50 rotates the drive shaft 40 via the gear box 51 while being installed at the central portion of the frame F in the longitudinal direction.

In addition, the planter (S) is disposed under the upper discharge unit 30, the seed discharged from each upper discharge unit 30 is supplied through each connection hose 90 to discharge to the ground It further comprises a plurality of lower discharge unit (60). On the other hand, the fertilizer is discharged directly to the ground through a separate hose 91 without passing through the lower discharge unit (60).

In addition, the planter (S) further includes a lower drive shaft 70 for driving the lower discharge unit (60).

In addition, the planter S connects the upper drive shaft 40 and the lower drive shaft 70 so that these drive shafts 40 and 70 interlock with each other, and eventually, the upper discharge unit 30 and the lower discharge unit 60. ) Further comprises a connection member 80 to be interlocked.

Hereinafter, the configuration of the seeding speed control device 200 of the second embodiment applied to the above-described seeding machine (S) will be described.

The seeding speed control apparatus 200 is disposed to contact the ground on one side (the opposite side of the connection member is installed) of the frame (F), the rotary wheel 210 rotates in accordance with the running speed of the planter (S) ).

In addition, the seeding speed control apparatus 200 of the second embodiment is connected between the drive shaft 211 of the rotary wheel 210 and the driven shaft 212 rotatably installed on the frame (F), the drive shaft ( It further comprises a power transmission member 220 for transmitting the rotational power of the 211 to the driven shaft (212).

The power transmission member 220 may include a drive chain gear 221 coupled to the drive shaft 211, a driven chain gear 222 coupled to the driven shaft 212, and the drive chain gear 221. And a chain 223 connecting the driven chain gear 222.

In addition, the power transmission member 220 may further include a chain cover 224 covering the drive chain gear 221, the driven chain gear 222, and the chain 223. Since the planter 100 is used in farmland such as Munnon, wet land, and is in an environment in which watery mud is bound to be buried. Accordingly, when dirt is deposited on the power transmission member 220, smooth driving may be prevented, and the chain cover and the chain are wrapped by the chain cover 224 to prevent the malfunction due to the soil. It is easy to remove the soil after the work.

The power transmission member 220 including the chain cover 224 is installed to be rotatable in a forward and backward direction about the driven shaft 212, as shown in Figure 8, the power transmission member 220 is It is preferable to be inclined at a predetermined angle toward the rear of the planter (S) toward the lower. This is one configuration for allowing the inclined power transmission member 220 and the rotating wheel 210 provided at its end to be autonomously flowed up and down in accordance with the state of the ground according to the elevation of the ground.

In addition, the free end (corresponding to the lower end in the drawing) of the chain cover 224 of the power transmission member 220 is elastically supported by the tension spring 250 to the frame (F). Accordingly, the power transmission member 220 and the rotation wheel 210 are elastically changed in accordance with the elevation of the ground while receiving the elastic force in the original direction.

If there is no tension spring 250, when the rotary wheel 210 descends from the high point of the ground to the low point, it suddenly drops (drops) and temporarily does not slip or rotate so that seeds and fertilizers may not be evenly seeded. However, since the tension spring 250 is installed, the rotation wheel 210 exerts an elastic force to always be in close contact with the ground, thereby preventing the above operation error in advance, thus increasing the reliability of the seeding. .

In addition, when the seeding and fertilizing operation is not performed or the seeding machine moves, the rotary wheel 210 does not need to contact the ground, and as shown in FIG. 10, the rotary wheel 210 is grounded on the frame F. The stopper pin 260 may be configured to limit the power transmission member 220 to be lowered to maintain the spaced apart from the power transmission member 220. The stopper pin 260 may be configured to be detachable so as to form a pinhole in the frame F, so as to be inserted into or taken out of the pinhole as necessary.

In addition, the seeding speed control apparatus 200 of the second embodiment further includes a rotation speed detection sensor 230 for detecting the rotation speed of the driven shaft 212.

Since the driven shaft 212 is connected to the drive shaft 211 of the rotary wheel 210 by the power transmission member 220, the rotation speed of the rotary wheel 210 is equal to the rotation speed of the driven shaft 212. . Accordingly, when the rotation speed of the driven shaft 212 is detected by the rotation speed sensor 230, the rotation speed of the rotation wheel 210 may be finally detected.

In addition, the second seeding speed control apparatus 200 further includes a controller 240 that proportionally controls the rotation speed of the driving motor 50 based on the rotation speed data transmitted to the rotation speed detection sensor 230. That is, the controller 240 controls the rotational speed of the driving motor 50 in proportion to the rotational speed data transmitted from the rotational speed sensor 230 for detecting the rotational speed of the rotating wheel 210. As a result, the rotation speed of the upper drive shaft 211 driven by the drive motor 50 is proportionally controlled according to the running speed of the seed drill S. FIG.

Therefore, the speed of the seeding machine and the speed of seeding and fertilizing can be precisely controlled electronically, thereby increasing the reliability of the seeding and fertilizing.

Hereinafter, a control method of the seeding rate automatic control device 200 of the second embodiment will be briefly described with reference to FIG.

Step 1, detect whether the driven shaft rotates (S10)

When the planter 100 is driven, the rotary wheel 210 is in contact with the ground is rotated, connecting the drive shaft 211 and the driven shaft 212 supported on the frame (F) of the rotary wheel 210 The driven shaft 212 is rotated by the power transmission member 220.

When the driven shaft 212 is rotated, it is detected by the rotation speed detection sensor 230 of the seeding speed control device 200 of the second embodiment, and the detected rotation data is transmitted to the controller 240 in real time. do.

Step 2, control the drive motor according to whether the driven shaft is rotated (S20)

When the driven shaft 212 rotates, it is detected by the rotation speed sensor 230 and the detection signal is sent to the controller 240. The controller 240 operates the driving motor 50 based on the signal. By doing so, the upper drive shaft 40 and the lower drive shaft 70 associated with the drive motor is driven to rotate. Accordingly, the upper discharge unit 30 and the lower discharge unit 60 is operated.

On the contrary, if the driven shaft 212 is in a stopped state, if the rotation speed detection sensor 230 also detects and transmits the detection signal to the control unit 240, the control unit 240 may drive the driving motor 150 based on the signal. ) Is shut down. Accordingly, the rotation of the upper drive shaft 140 and the lower drive shaft 170 is stopped.

Although the control logic is relatively simple, by combining the mechanical and electronic configuration, the seeding and fertilizing operation can be precisely performed according to the movement speed of the seed drill, thereby helping to improve the reliability of the work.
