Description

[Detailed description of the invention] The present invention relates to a rice transplanting device.

FIG. 1 is a plan view showing the relationship between the running wheels, floats, and planting device of a conventionally known rice transplanting device.

In the figure, AA is a running wheel, B is a center float, C is a right float, and D is a left float. A cutout part EF is provided on the left and right sides of the rear part of the center float B, and a pair of left and right plants are provided in the cutout part EF. A planting device GH was arranged, and both the left and right floats CD were provided with a notch IJ inside the rear part, and each planting device KL was provided in the notch IJ.

Further, the running wheels AA include a chain case M that can freely move up and down.
The shaft was fixed by N.

The disadvantages of the rice transplanting device shown in Fig. 1 above are that the land left by the wheel A cannot be leveled sufficiently, and that it knocks down adjacent rows.
If the paddy field is deep, grooves are formed in the surface layer of the paddy field using a chain case MN.

In other words, the relationship between the wheels AA and the planting device G row KL is such that one wheel A is located between the planting device GkO and the other wheel A is located between the planting device LH. Since the left and right float CD is only in a small portion indicated by the arrows, it is not possible to level the ground sufficiently.

In addition, there are long protruding parts on the outside of each planting device KL shown as tt/, so when the rice is transplanted by driving near already planted seedlings, the mud is pushed against the adjacent seedlings (adjacent rows).
This was a flaw in that it could push the person down.

Furthermore, when the wheel AA is supported by a chain case MN that moves up and down as shown in Figure 1, the case may dig a groove on the surface of the paddy field, but no countermeasures have been taken. Ta.

Therefore, in the present invention, a central float is located at the rear between a pair of left and right running wheels, a right float and a left float are respectively arranged on the left and right sides of the central float, and the left and right sides of the rear part of the central float are respectively cut out. A pair of left and right planting devices are provided in the cutout portions of the right and left floats, and the right float and the left float are each provided with a planting device in the cut arrow portions of the cutout portions of the right and left floats. It is attached via a rotating chain case, and the chain case is positioned between the planting device and the planting device, respectively, and the wheels are attached to the part where the planting device located outside is planting. This is a rice transplanting device located outside the vicinity.

To explain with the drawings, FIG. 2 shows an embodiment in which four rows are planted, and numerals 1 and 1 are running wheels of a commonly known rice transplanting device.

A pair of left and right wheels 1, 1 are provided.

A central float 2 is provided in the rear position between the wheels 1,1.

The rear part of the central float 2 is cut out on the left and right sides to form cutout parts 3 and 4, respectively.

A pair of left and right planting devices 5 and 6 are arranged within the cut arrow portions 3 and 4.

Therefore, the planting devices 5 and 6 plant the plants on the ground leveled by the central float 2.

A right float 7 and a left float 8 are provided on the left and right sides of the center float 2, respectively.

Each of the floats 7 and 8 is cut out at the rear of each outer side to form cutout portions 9 and 10.

Each cutout portion 9, 10 has a planting device 11. 12
is placed.

The wheels 1, 1 are each attached to a chain case 13.13 that rotates up and down relative to the aircraft body, and are configured to move up and down as the case 13.13 rotates up and down. Ru.

The vertical rotation of the chain cases 13, 13 is performed by a hydraulic device 14 operated by a sensor.

Said chain case 13. The left and right floats 7 and 8 of the wheel 18 are formed in the following relationship.

That is, the chain case 13 is located between the parts to be planted by the planting devices 5, 11 and 6, 12, and the wheel 1 is located near the outside of the part to be planted by the planting devices 11, 12.

And, each internal measurement 15, 15 of the left and right floats 7, 8 faces the rear of the chain case 13, 13,
3. Formed in a state where the groove formed by 13 is leveled,
Each outer side 16.16 of the left and right floats 7, 8 has an axle i1,
Make the marks from step 1 bulge outward to level the ground.

In the figure, 17 is a front wheel, and 18 is a seedling tank.

Further, the sensor is preferably implemented by a central float 2, which is illustrated in the embodiment drawings.

Furthermore, the lugs 19 of each wheel 1, 1 are attached to protrude outward from the rim 20.

Since the present invention has the above-described configuration, when the vehicle moves forward using the traveling wheels 1, 1, the seedlings stored in the seedling tank 18 are planted one by one by the respective planting devices 5, 6, 11, and 12.

In this case, when the paddy field is deep, chain case 13.13
The lower surface of the tree reaches the surface of the water mound and forms a groove, which may hinder the planting work, but in the present invention,
The attachment positions of the chain cases 13, 13 in plan view are set between the parts to be planted by the planting devices 5, 11 and between the parts to be planted by the planting devices 6, 13,
12 between the parts to be planted, and the right float 7 is located between the planting devices 5 and 11, and the left float 8 is located between the planting devices 6 and 120. Therefore, even if the chain case 1
According to 3.13, even if a trench is dug on the surface of a paddy field, it will be immediately leveled and leveled, and the planting work will not be hindered in the slightest.

In addition, in the conventionally known case, the running wheels AA were located between the planting devices GK or between the HLOs, so the rut interval T
However, in the case of the present invention, the running wheel 1
, 1 is located outside the planting device IL12 that attaches the outside, and is connected to the adjacent row a that has already been planted and the planting device 11
．． 12, the rut interval T' is very narrow, and the machine can be planted smoothly without tilting over slight irregularities.

Further, as described above, the traveling wheels 1, 1 are connected to the planting device 11.
Even if it is located outside of 12, the left and right floats 7 and 8
Each of the outer sides 16, 16 is formed in a bulging manner so that the marks left by the wheels 1, 1 can be evened out, so that the marks left by the wheels 1, 1 can be completely evened out.

In this case, the outer sides 16, 16 of the left and right floats 7, 8 are as follows:
Although the configuration is such that it comes very close to the adjacent strip a, the length t on the front and rear sides in the case of the known example shown in FIG. 1 is shorter as shown in t' in FIG. There is no such thing as passing a.

The present invention has the above configuration and operation, and a pair of left and right traveling vehicles @1
, 1, and a right float 7 and a left float 8 are respectively arranged on the left and right sides of the center float 2. The left and right sides of the rear of the center float 2 are cut out and A pair of left and right planting devices 5, 5 are provided in the cut-arrow portions 3, 4, and the right float 7 and left float 8 are respectively cut out on the outside of their rear parts, and planting devices 11, 12 are installed in the cutout portions 9, 10, respectively. The wheels 1, 1 are each provided with a chain case 13 that is pivoted to the aircraft body and that moves up and down.
．． The chain case 13.13 is located between the planting devices 5 and 11 and between the planting devices 6 and 12, respectively, and the vehicle transports 1 and 1 are located on the outside. Since the rice transplanting device 11 and 12 are located outside the area to be planted, the right float 7 or the left float 8 has a notch 9 or 10 formed in the area adjacent to the adjacent row a. Therefore, there is no crowding around the adjacent row a, and therefore there is an effect that there is almost no pushing down of the adjacent row a, and the wheels 1 and 1
is located outside the part to be planted by the planting device 11, 12, so the rut interval T' is wider than T in the known example, and the chain case 13, Chain case 1 even if wheels 1 and 1 are attached to 13
When the center float 2 is used as a sensor by leveling out the marks formed by the floats 3 and 13, it can be expected that the sensor action will be improved.
