Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the arrangement structure of each working device in a submerged soil composite working machine.

(b) Conventional technology Conventionally, as an example of a submerged work machine,
JP-A-166411 describes a device that includes a fertilizing section and a sowing section.

In addition, in Japanese Utility Model Application Publication No. 55-25482, a notch is provided at the rear end of the float, a dispersion port for sowing, etc. is located in the notch, and a trench plate and a soil covering plate are supported on the same float. The structure is described.

Further, Japanese Patent Publication No. 35-1304 describes a structure in which a seeding section and a fertilizing section are installed with a gap between them.

(c) Problems to be solved by the invention However, in all of the flooding machines described in the above publication, after completing the series of fertilizing operations of fertilizing trench → fertilization → fertilizing and covering soil, →Seeding→
Since there is no structure that can complete the series of sowing operations of sowing and covering with soil, there is a problem that the seed rice is exposed to fertilizer and causes so-called fertilizer burn.

In addition, it has a structure in which the trench plates and soil covering plates for fertilization and seeding are supported on the same float, making it possible to improve the accuracy of fertilization depth and seeding depth. Therefore, there is a problem that it is not possible to ensure good fertilization and sowing operations.

(d) Means for solving the problem Therefore, in the present invention, the fertilization part and the seeding part are placed on a float, and a central notch is formed in the shape of a notch from the center of the float toward the rear end. The lower end opening of the fertilizing hose provided in the fertilizing section is exposed to the front end of the central notch, and the fertilizing groove plate and the fertilizing soil plate are respectively protruded downward from the float in front and rear proximity to the lower end opening. Further, a notch is formed in the rear end of the float so as to be positioned at a certain distance behind and to the side of the fertilizer covering soil plate at a certain distance,
The lower end opening of the chute provided in the sowing section is exposed to the notch, and the sowing trench plate and the sowing soil covering plate are respectively protruded downward from the float in front and rear proximity to the lower end opening. The present invention aims to provide a structure for arranging each working device in a working machine.

(E) Functions and Effects According to the present invention, the following functions and effects occur.

In other words, the series of fertilization work of fertilizing trench → fertilization → fertilizing and covering soil, and the series of sowing work of sowing trench → sowing → sowing and covering soil are spaced apart from each other in the front and back direction, and also in the left and right width direction. Because the plant is opened open, the sowing work completion position is always offset backward and laterally from the fertilization work completion position, and as the machine moves forward, the sowing work is performed first. Since this is carried out at a position lateral to the completed position, it is possible to reliably prevent so-called fertilizer burn on the seed rice due to fertilizer.

In addition, the lower end opening of the fertilization hose should be placed so that the lower end opening of the chute faces the central notch and notch provided on the same float, respectively, and the groove plates and soil covering plates for fertilization and seeding should be connected to the respective lower end openings. Because it is placed close to the front and back of the float and protrudes downward from the float,
By stably supporting each part on the same float, it is possible to ensure fertilization work with good fertilization depth accuracy and sowing work with good sowing depth accuracy.

(F) Example The example of the present invention will be explained in detail based on the drawings.

2' to the lower end opening 23 of the chute 21, 21',
23' is open, and the chute 21, 2
Seed-seeding trench plates 24, 24' and seed-covering soil plates 25, 25' are provided at the front and rear adjacent positions of the lower end openings 23, 23' of 1', respectively.
It is installed vertically.

In addition, the relative positions of the groove plate and soil covering plate of fertilization part a and the groove plate and soil covering plate of sowing part b are such that fertilization part a is located in the front, and sowing part b is located in the rear. Moreover,
They are spaced a certain distance in both the front and rear directions and the left and right directions.

In addition, the weeding part c is arranged above the rear part of the float m, and the herbicide storage hopper 26 is disposed in the sowing hopper 19.
A weeding pipe 27 is piped from the hopper 26, and a herbicide spraying port 28 is formed at both ends and at a predetermined circumference side of the pipe 27, and the weeding part 27 is disposed next to the hopper 26. Herbicides can be sprayed onto the soil surface after sowing and fertilization. Here, the herbicide spraying port 28 is formed so that the herbicide spraying direction is diagonally rearward.

As mentioned above, the positional relationship of the fertilizing part a, the sowing part b, and the weeding part c in the composite working part 1 is arranged in the order of the fertilizing part a, the sowing part b, and the weeding part c from the front, and in particular, Fertilization groove plate 17, 1 of fertilization section a
7', the sowing groove plates 24, 24' of the sowing section b, and the herbicide spraying port 28 of the weeding section c are arranged in order from the front.

Seeding groove plates 24, 24', lower end of chute 23,
23', sowing soil covering plates 25, 25' are arranged in a line in the front-rear direction on both sides, and at the inside position of the fertilizing groove plates 17, 17', the lower end of the fertilizing hose 15, 15', and the fertilizing soil covering plates 15, 15'. The plates 18 and 18' are arranged in a line in the front-rear direction, and are configured so that trench-cutting and soil-covering operations are performed separately at left and right positions.

The embodiment of the present invention is constructed as described above, and when carrying out fertilization, direct sowing, and herbicide spraying work in flooded soil, the composite work unit 1 is moved to the field while traveling by the traveling machine 3. In the compound working section 1 connected to the front of the traveling machine 3, the compound working section 1 is held on the field water surface by the float m, and the fertilizer is spread by the fertilization groove plates 17, 17'. A trench is made, and fertilizer is applied from the fertilization hopper 12 to the trench through the fertilization hoses 14, 14', and the soil is covered with soil plates 18, 18'.

Next, the sowing groove plate 2 is placed behind and on the lateral side.
4 and 24', sow seeds directly into the grooves from the sowing hopper 19 via the chute 21 and 21', and cover with soil using sowing soil plates 25 and 25'.
Therefore, it is possible to reliably prevent so-called fertilizer burn on the seed rice due to fertilizer.

Further, at the rearmost position, the herbicide is sprayed from the herbicide storage hopper 26 through the weeding pipe 27, and the herbicide is sprayed onto the soil surface where the fertilization furrow and sowing furrow have already been covered. .

Therefore, the depth of the trench at the time of sowing and fertilizing is accurately formed by each trenching board 17, 17' and 24, 24', and the trench is created for each sowing and fertilizing operation. In addition, the soil condition is not affected by other trenching plates, soil covering plates, etc., and high-precision work can be performed despite the combination mechanism of the fertilizing section and sowing section. Because it is located behind the fertilizing groove plate, it is not affected by the fertilizing groove plate, allowing for particularly high-precision work, and the herbicide is sprayed on the soil surface.
The herbicide does not enter the furrow and the weeding effect can be increased.
