The rear end of the corresponding discharge pipe 31 and the upper end of the seeding grinder 29 are connected by a flexible tube 36, and the seed fir fed into the discharge pipe 31 is sent by the air blown out of the air chamber 30. And spread in the seeding groove. A backfilling tool is provided on the lower surface of each float 27 so that the soil can be raked by sliding of the float 27 so as to fill back the sowing groove where the seed fir has been scattered. In addition,
The discharge pipe 31 and the valley are each composed of four pieces, and the four tubes 36 whose front ends are attached to the respective discharge pipes 31 are divided into two parts on the way to form eight terminals.
It can be configured to be connected to one of the individual seeding cutters 29.

[0009] The fertilizer applicator 3 is configured as follows. A pair of fertilizer tractors 37 are fixed to each float 27 inside the seed cultivator 29, and eight sliding fertilizer grooves are formed on the mud surface by sliding. A horizontally long pipe-shaped air chamber 38 is provided behind the seat 13 for the traveling body 1.
It is fixed to. Eight discharge pipes 39 protrude rearward from the air chamber 38, and air blown by a blower 40 provided on the right side thereof is blown out. A fertilizer tank 41 is arranged on the discharge pipe 39 in front of the seed tank 31. The fertilizer tank 41 has eight valleys which are made horizontally long and are arranged side by side at the bottom. The upper entrance of the fertilizer tank 41 is covered with a lid 42, and the lid 42 is attached to the fertilizer tank 41 such that the rear part rotates around a horizontal axis 43. When the lid 42 is turned backward, the entrance of the fertilizer tank 41 is opened to cover the seed tank 33 (a chain line in FIGS. 1 and 2).

When each of the above-mentioned valleys and the discharge pipe 39 are connected and fixed by a feeding cylinder 44, and a rotor (not shown) therein is rotated by the power of the engine 9, a fertilizer tank 41 is formed.
The granular or powdered fertilizer therein is continuously fed to an intermediate portion of the discharge pipe 39. Corresponding discharge pipe 39
The rear end of the fertilizer is connected to the upper end of the fertilizer grooving machine 37 by a flexible tube 45, and the fertilizer fed into the discharge pipe 39 is fed by air blown out of the air chamber 38, and the fertilizer is applied. It is designed to be sprayed in the groove. The fertilizer furrows on which the fertilizer has been applied are backfilled as before.

As described above, as the traveling body 1 advances, the seed fir and the fertilizer are simultaneously sprayed into the mud, so that direct sowing is performed. When this work proceeds and the fertilizer in the fertilizer tank 41 is reduced (or lost), the advancement of the traveling vehicle body 1 is stopped, the lid 42 is turned backward to open the entrance thereabove, and the spare fertilizer is put therein. Start working. The same applies when the amount of seeds in the seed tank 33 is reduced (or lost). When the lid 42 is turned to open the entrance of the fertilizer tank 41, the lid 42 rides on the seed tank 33 and covers the entrance thereabove. As a result, the seed fertilizer is not supplied to the seed tank 33 by mistake. Further, the lid 34 is lifted and the seed tank 33 is lifted.
When the entrance on the top is opened, the lid 42 turns forward and closes the entrance of the fertilizer tank 41, so there is no danger of replenishing the seed fir into the fertilizer tank 41.

The hitch 1 shown in FIGS.
When 7 is raised, the seed tank 33 is raised. In other words, even if the fertilizer is put into the fertilizer tank 41 and the lid 42 is forgotten, if the flooded direct sowing machine comes to the headland and turns and raises the hitch 17 (seeding device 2), the seed tank 33 is By pushing and turning the lid 42, the entrance of the fertilizer tank 41 is automatically closed.

A missing particle sensor 46 can be provided between the seeding groove generator 29 and the tube 36 as shown in FIG. The seeding grinder 29 is formed in a U-shaped cross section with the rear open. The tube 36 and the seeding groove generator 29 are connected via the connecting pipe 47. The connecting pipe 47 is made of a flexible or hard resin, and is formed into a shape that extends upward when viewed from the side and then bends forward.
Is installed. When the seeds adhere to the lower end of the seeding grinder 29 or the lower end of the connecting pipe 47 with moisture, and the accumulation of the seeds proceeds and the holes of the connecting pipe 47 are clogged, the missing particle sensor 4
6 is operated to inform the operator of this. According to this configuration, the missing particle sensor 46 is connected to the connecting pipe 47.
Is provided on the inside of the bend, so that the seeds blown by air flow along the outside of the bend and are less likely to violently collide with the missing particle sensor 46, thereby reducing the damage. Therefore, it is not necessary to say that this configuration can be used for the fertilizer application device 37 for spraying the granular fertilizer.

FIGS. 4 and 5 show another spreader. In other words, the apparatus 50 for dispersing granular powder is mounted on the traveling vehicle body 1 as described above. The spraying device 50 is configured as follows. A mounting frame 51 is detachably provided on the hitch 17, and a machine frame 52 is fixed thereafter. Three long and short pipes 53a, 53b, 53c are fixed to the machine frame 52 horizontally at the same center, and the beam 5
It is 3. Each pipe 53a, 53b, 5
Nozzles 54 attached downward to 3c are arranged at equal intervals.

A horizontally long pipe-shaped air chamber 55 is fixed on the column 16, from which six discharge pipes 56 project rearward. A blower 57 is provided on the machine frame 52,
The discharge port and the right side of the air chamber 55 (as viewed from the front)
The ends are connected by a hose 58 so that the air blown into the air chamber 55 from the blower 57 is blown out from each discharge pipe 56.

A horizontally long tank 59 is arranged above the discharge pipe 56. The tank 59 is formed in six valleys whose bottoms are arranged side by side.
When the rotor (not shown) in the delivery cylinder 60 is rotated by the power of the engine 9, the fertilizer and the pesticide in the tank 59 are continuously delivered to the intermediate portion of each discharge pipe 56. Has become. Tubes 61 extend rearward from the rear ends of the respective discharge tubes 56, each reaching the two nozzles 54. Then, when the traveling vehicle body 1 is moving forward in the field, the fertilizer and the pesticide fed to the discharge pipe 56 are sent through the tube 61 by air and sprayed from the respective nozzles 54 onto the surface of the field with a wide width. It is made to be done.

A pair of marker nozzles 62 are provided at the outer end of the pipe 53a. A tank 63 is attached to the left of the tank 59, and contains a liquid harmless to crops colored red or yellow. The liquid is supplied to the lower delivery valve 64
Through the tube 65 to reach the marker nozzle 62. Then, the switch 66 is set to “OF”
F ”, the PTO clutch 6
8 is "cut", the rotation of the rotor is stopped, and the delivery valve 64 delivers the liquid, and the liquid is ejected from the marker nozzle 62 onto the field or crop for several seconds. The marker nozzle 62 is arranged such that the nozzle 54 at the outer end ejects the liquid to the outer end where the fertilizer or the pesticide is sprayed on the field.

In this type of sprayer, since the beam 53 is configured to be significantly longer than the width of the traveling vehicle body 1, the position of the outer end of the fertilizer or pesticide sprayed by the nozzle 54 at the side end is difficult for the operator to understand. . For this reason, it is difficult to find out where to place the spreader when resuming the work after making a U-turn on the headland, and work such as setting up a pole at the position of the outer end has been performed.

In contrast, according to the above configuration, when the sprayer reaches the headland and stops spraying fertilizer or the like, the colored liquid is ejected from the marker nozzle 62 to the outer end of the spray width. Therefore, the width of the fertilizer and the like spread by the sprayer on the outward route becomes clear. Therefore, the place where the spreader is located on the return path after the U-turn is easily determined.
In addition, a granular material can also be used instead of a liquid.

[0020]

According to the present invention, for a pair of tanks to which different kinds of powders are supplied, when the lid of one tank is opened, the other tank is covered, so that the inlets on both tanks are not opened at the same time. Therefore, the malfunction of supplying different powders to the tank is reduced.
