Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a four-row rice transplanting device.

(Prior art) A conventionally known four-row rice transplanting device has the structure shown in Fig. 1, where A is a running wheel, B is a center float, C is a right float, and D is a left float. Notch part E
, F are provided, and a pair of left and right planting devices G and H are arranged on the left inside the cutout portions E and F, and the right floats C and D are both provided with notch work on the inside of the rear part, J is provided and the notch work is done, Each planting device is provided with L at J, straight edges M and N are provided on the outside, and at the front of the central float B there is a mud extrusion part 0. It formed a P.

(Problem that the invention attempts to solve) What are the drawbacks of the four-row rice transplanting device shown in Figure 1 above?

Not being able to level the ground sufficiently at the wheel mark A, knocking down the adjacent rows, and each notch on the inside rear of the right float C and left float D.1. The purpose is to knock down L with a mud wave on the planting device installed at J. That is, the mud extrusion section 0.0 at the front of the central float B. The muddy wave pushed out by P knocks over the seedlings planted by L on the planting device.

In addition, the planting device has a protruding part marked ``Mi, Mi'' on each outside of L, so when driving near already planted seedlings and planting rice, it is easy to push down adjacent seedlings (adjacent rows). (Means for solving the problem) Therefore, in the present invention, in a device having a running wheel, a float, and a planting device, a pair of left and right running wheels is used. A central float is located behind the center float, a right float and a left float are respectively arranged on the left and right sides of the central float, and mud extrusion parts are formed on the left and right sides of the front part of the central float so as to protrude outward toward the rear. The left and right sides of the rear part of the center float are respectively cut out, and a pair of left and right planting devices are provided in the cutout parts, and the right float and the left float are formed with straight edges on the inside, and have a notch on each outside of the rear part. The structure is a 4-row rice transplanting device in which a section is provided and a planting device is provided in each of the notched sections.

One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 represents the running wheels of a commonly known four-wheeled rice transplanting device.

Running wheels 1. A pair of left and right l is provided. Running wheel 1
．． A central float 2 is provided in the rear position between 1 and 1.

The rear portion of the central float 2 is cut out on both left and right sides to form cutout portions 3.4. A pair of left and right planting devices 5 and 6 are arranged within the cutout portion 3.4. central float 2
A right float 7 and a left float 8 are provided on the left and right sides of /lτ. Each float 7.8 is cut out at its outer rear part to form a cut-out portion 9.10, and each float 7.8 is
．． 10, a planting device left 11, 12 is arranged, respectively. The inside of each front t1 float 7.8 is formed with a long straight edge 13.14 from the front end to the rear end. In front of the straight edge 13.14, said running wheel 1.1
are installed, and the running wheels 1. l and planting equipment 5.6.11
．． 12, one running wheel l is the planting device 5.11
The other running wheel 1 will be located between the planting devices 6.12, and the straight edge 13.14 of each left and right float 7.8 will be located between each planting device 6.12. 5.11 and the planting device 6.12, so in the end, the trace of the running wheel l, left l is traced back and forth by the straight edge 13 of the long I/1 float 7.8.
．． The ground will be leveled on the 14th. The central float 2 is
Either it is a sensor itself or a separate sensor is installed.

Mud extrusion parts 15 and 16 are formed on the left and right sides of the front part of the central float, and protrude outward toward the rear.

Fig. 4 is a side view of the whole, in which 17 is the front wheel;
8 is an auxiliary seedling tank, and 19 is a seedling tank.

(Operations and Effects) Since the present invention has the above-described configuration, as is clear from the plan view of FIG. Planting equipment 6.12
The straight edge 14 of the left float 8, which is long in the front-rear direction, is located between them. Since the running wheels l, 1 are located between the four planting devices 5.11 or 6.12, the wheel traces are located between the straight edge 13 of the right float 7 and the left The straight edge 14 of the float 8 allows for completely flat leveling.

Therefore, as in the known example shown in FIG. The wheel marks of the running wheels are insufficiently leveled by the front and rear short floats,
Therefore, it is possible to prevent an adverse effect on the planting operation by the planting device 5 or to prevent irregular pressure from being applied to the center float, which would make its function as a sensor insufficient.

Furthermore, the left and right floats 7.8 of the four-wheeled rice transplanting device of the present invention each have cutout portions 9 and 10 formed on their outer sides, and the planting devices 11.12 are disposed in the cutout portions 9.10, respectively. When compared with the known example shown in FIG. 1, it is possible to eliminate the protruding part of the sentence ``stand'' shown in FIG.

Even if a protrusion occurs, it can be made significantly smaller than that shown in FIG. Therefore, when driving alongside already planted seedlings and planting rice, there is almost no pushing down or bending of adjacent rows.

Furthermore, as described above, in the present invention, since there is no protruding part, it is easy to operate when turning. That is,
As is well known, the larger the lateral width, the more difficult the turning operation becomes, but according to the present invention, since the lateral width can be reduced, turning becomes easier.

In addition, as shown in FIG. 1, in the conventional method, L is attached to the planting device provided at each of the notches and J at the inner rear of the right float C and the left float D. However, in the present application, as shown in Fig. 2, the inside of each of the left and right floats 7 and 8 is long from the front end to the rear end. Since the straight edges 13 and 14 are formed, there is no need to worry about heat.
