Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a float for a rice transplanting device and a planting device.

FIG. 1 is a plan view showing the relationship between a float and a planting device of a conventionally known rice transplanting device.

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

The disadvantages of the rice transplanting device shown in FIG. 1 above are that it is not possible to level the ground sufficiently at the wheel A mark, and that it knocks down adjacent rows.

In other words, the relationship between wheel A and planting device GHKL is such that wheel A is located between planting device GK and planting device LH, but the left and right floats CD that level the ground after the wheels AAO are moved according to the arrows. As it is only a small part of the land shown as , it is not possible to level the ground sufficiently.

In addition, since there is a protruding part indicated as LL' on each outside of the planting device KL, when the planting device KL immediately runs near the planted seedlings for rice transplantation, it is possible to prevent the neighboring seedlings (adjacent rows) from being pushed down. Yes, there was a flaw in this respect.

Therefore, the devised invention of the present invention includes a running wheel, a float,
In a device having a planting device, a central float is located at the rear between a pair of left and right running wheels, and a right float and a left float are respectively arranged on the left and right sides of the central float,
Either the left and right sides of the rear part of the center float are cut out and a pair of left and right planting devices are provided in the cutout portions, or the center portion of the rear portion is cut out and a planting device is provided in the center cutout portion, and the right float and the left float are cut out. The rice-transplanting device has a cut-arrow portion on each outer side of its rear part, and a planting device is provided in each of the cut-out portions, and the central float serves as a sensor for moving the rice-transplanting device one step down.The rice-transplanting device has a float and a planting device structure. It is something.

To explain with the drawings, FIG. 2 shows an example in which four rows are planted, and numeral 1 indicates 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 at the rear position between the wheels 1, 10.

The rear part of the central float 2 is cut out on the left and right sides to form cut arrow 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 soil 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.

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

A planting device 11.12 is arranged in each cutout 9, 10, respectively.

The respective floats 7, 8 are both attached to the rear of the vehicle 1, 1, but as described above, the relationship between the wheels 1, 1 and the planting devices 5, 6, 11, 12 is such that one wheel 1 is located between the planting devices 5 and 110, and the other wheel 1 is located between the planting devices 6 and 110.
, 120, and the left and right floats 7, 8 are located between the planting devices 5, 11 and 6, 12, so the traces of the wheels 1, 1 end up being located between the planting devices 5, 11 and 6, 12. The ground will be leveled using long left and right floats 7 and 8 in the front and back.

The central float 2 itself becomes a sensor, or
Or, as shown in FIG. 5, another sensor 13 is installed.

FIG. 5 shows a known example of the sensor 13. When the sensor 13 is activated, the tension clutch 14 is activated, and the hydraulic device 15 is activated by the clutch 14 to move the wheel 1 up and down, thereby moving the wheel 1 up and down relatively. This is to move the rice transplanting device upward.

If the device shown in FIG. 5 is used for the center float 2 in FIG. 2, the rice transplanting device in FIG. 2 can be moved up and down.

FIG. 3 shows an example of three-row planting as opposed to the four-row planting shown in FIG. is arranged.

Fig. 4 is a side view of the whole, in which 18 is the front wheel;
9 is an auxiliary seedling tank, and 20 is a seedling tank.

Since the present invention has the above-described configuration, as is clear from the plan view of FIG. 2, the right float 7, which is long in the front-back direction, is located between the planting devices 5 and 11.

Furthermore, a left float 8 that is long in the front-rear direction is located between the planting devices 6 and 12.

The wheels 1, 1 are originally located between the planting devices 5, 11 or 6, 12, and leave wheel marks between each planting device 5, 11 or 6, 12. However, the wheel marks are leveled out by the right float 7 and left float 8 mentioned above.

Therefore, as shown in the known example in Fig. 1, the wheel marks may be insufficiently leveled, which may adversely affect the planting work by the planting device, or may apply irregular pressure to the central float, making it difficult to function as a sensor. to prevent the situation from becoming inadequate.

Furthermore, the left and right floats 7 and 8 of the present invention have cut-arrow portions 9 and 10 formed on the outside thereof, and planting devices 11 and 12 are arranged in the cut-out portions 9 and 10, respectively. Compared to the known example, it is possible to eliminate the protruding portion tt' shown in FIG. 1.

Even if a protrusion does occur, it can be made significantly smaller than in FIG.

Therefore, when the vehicle runs alongside already planted seedlings for rice planting, there is little chance of pushing down or bending the adjacent rows.

Further, as described above, in the present invention, since there is no protruding portion tt', the operation when turning is facilitated.

That is, as is well known, turning becomes more difficult as the width increases, but since the width can be reduced according to the present invention, turning becomes easier.

As described above, the present invention has a running wheel, a float, and a planting device, in which the central float 2 is located behind the pair of left and right running wheels 1, 1, and the left and right of the central float 2 is A right float 7 and a left float 8 are arranged on both sides, and the rear left and right sides of the central float 2 are cut out, and a pair of left and right planting devices 5 and 6 are installed in the cutout parts 3 and 4, respectively.
or a planting device 17 is provided in the central cut arrow part 16 by notching the central part of the rear part, and the right float 7 and the left float 8 are provided with notch parts 9 and 10 on each outer side of the rear parts thereof. 9 and 10, and the central float 2 is used as a sensor to move the rice transplanting device up and down, so based on the above-mentioned reasons, it is necessary to have a structure that perfectly evens out the wheel marks, and the adjacent This can be expected to have the following effects: not toppling the rows, making it easier to turn, and ensuring reliable sensing by the central float 2.
