Conventionally, the hopper part of fertilizing and seeding machines has been made of transparent synthetic resin, so it is possible to monitor from the outside whether the fertilizer or seeds inside are gone. However, clogging in the feeding device or accumulation in the guide pipe section was difficult to see from the operator's position, and there was often a delay in discovering missing particles.

In particular, when a roller frame is arranged below the feeding device so that the roller frame can move up and down following the soil covering roller, the roller frame 36 must be blocked by the roller frame in order to have a sturdy frame structure. This caused a problem in that the grains were not visible at the bottom of the guide pipe, making it impossible to monitor the state of missing grains.

In order to solve these problems, the present invention is designed so that the inside of the guide pipe arranged inside the roller frame can be seen.

There are hopper shutters 40 and 39 at the bottom of the fertilizing hopper 1 and the seeding hopper 2.
The hopper shutters 40 and 39 are configured to be freely put in and taken out, and by closing the hopper shutters 40 and 39, the fertilizing hopper 1 and the seeding hopper 2 become portable containers.

The feeding device is composed of feeding rolls 5, 6 which are fixed in feeding cases 56, 62 by feeding shafts 7 and are rotatable in the vertical direction, and fitting holes 5a, 6a provided on the outer peripheries of the feeding rolls 5, 6. , the parts that overflow after being fitted into the fitting holes 5a and 6a are scraped off by scraping brushes 33 and 34. A drive gear is arranged on the side of the feed roll 5, and by attaching the seeding feed device B to the fertilizing feed device A, the drive gear meshes with the other drive gear, thereby causing the feed roll 6 to rotate. Communicating.

The grains fed out by the feeding rolls 5 and 6 are
It is collected by guide funnels 60 and 61 and transferred to bellows rubber pipes 17 and 18. The bellows rubber pipes 17 and 18 are fixed to a roller frame 36 that moves up and down together with the soil covering roller 12.
Inside the roller frame 36 is a transparent funnel 19a,
20a is arranged. The transparent funnel 19a, 2
0a is connected to a fertilizing guide pipe 19 and a seeding guide pipe 20, which are also made of transparent synthetic resin.

The present invention relates to a structure for monitoring the fertilization guide pipe 19 and the seeding guide pipe 20.

Conventionally, guide funnels 60, 61 and transparent funnel 19 were used.
The space between a and 20a is considered to be an inheritance space,
I could see the grains falling. However, there is a problem in that particles fly out from these parts due to strong winds or vibrations, so in this configuration, bellows rubber pipes 17 and 18 are interposed in these parts. As a result, it has become impossible to determine the presence or absence of missing grains in the conventional inheritance space.

In order to eliminate this problem, the present invention provides viewing windows 36a and 36c on the roller frame 36,
It is possible to monitor the inside of the seeding guide pipe 20, which is arranged inside the roller frame 36.

In Figures 3 and 4, the roller frame 3
6 is shown. Since the front end of the roller frame 36 is vertically movably supported on the fertilization/seeding frame 58 by the parallel links 24 and 23, and the rear part is moved vertically along the soil surface by the soil covering roller 12, it is necessary to increase the strength. , it has a framework structure. And sowing guide pipe 2
0 needs to be located between the groove-making disks 10 located directly below the roller frame 36,
It inevitably passes through the inside of the roller frame 36. A roller frame 36 configured as a framework and a seeding guide pipe 2 inside it
0 would normally be impossible to monitor from the outside.

In the present invention, viewing windows 36a and 36c are provided on the side of the roller frame 36 so that the seeding guide pipe 20 within the roller frame 36 can be monitored.
It has been established. The viewing window 36a is inclined in the same direction along the direction in which the seeding guide pipe 20 is inclined forward. Peep window 3
6c is bored in the rear surface of the roller frame 36.

In addition, the fertilization guide pipe 19 is arranged in a side strip slightly apart from the roller frame 36, since fertilizer burn may occur if the fertilization is applied at the same time as the sowing position.
It protrudes outward from the opening 36b and can be seen by the operator. Further, both the fertilization guide pipe 19 and the seeding guide pipe 20 are made of transparent synthetic resin so that the interior of the operator can be monitored. Reference numeral 36d denotes a bracket portion for fixing the support rod 12a of the soil covering roller 12.

(f) Effects of the invention Since the present invention is constructed as described above, it has the following effects.

First, the grains fed out in fixed amounts by the feeding device are fed into the bellows rubber pipe 18 from the guide funnel 61, so even if there are missing grains or stagnation in that part, the operator cannot see them. It is.

In the present invention, the viewing windows 36a and 3 are provided in the roller frame 36 below the bellows rubber pipe 18.
6c, the seeding guide pipe 20
Since the sowing guide pipe 20 is made of transparent synthetic resin, it is possible to check the passage of seeds inside the sowing guide pipe 20.

Second, by opening the viewing windows 36a and 36c parallel to the seeding guide pipe 20, the viewing windows can be used to easily monitor the seeding guide pipe 20 without reducing the strength of the roller frame 36. It is.

Thirdly, the seeding hopper 2 and the seeding feeding device B
The side of the roller frame 36 is supported on the side of the tractor's work equipment lifting device, so it cannot move up and down depending on the unevenness of the soil. However, the roller frame 36 is supported by the parallel links 24 and 23, Since the soil covering roller 12 is fixedly installed, it can move up and down according to the unevenness of the soil, and the distance between the trench cutting disk 10, soil covering disk 11, and sowing guide pipe 20 and the soil surface is always constant. It is also possible to keep the seeding depth constant.

Fourthly, since the roller frame 36 can be constructed in the shape of a box made of iron plates, the roller frame 36 can be made light in weight and strong.
