Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a fertilizing and seeding machine that can be used to change the width of the fertilizing and seeding machine or to change the sowing unit when rotary tillers with different tilling widths are attached. The present invention relates to a configuration for facilitating the increase/decrease of the amount.

(b) Prior Art Fertilizer seeding machines have been known in which several seeding units are arranged in parallel and are driven by pressure rollers at the rear.

These had a seeding unit and drive shaft directly supported by a frame pipe connected to the tractor's depth bar.

(c) Problems that the invention aims to solve When the depth bar is directly and integrally attached to the frame pipe connected to the depth bar of the tractor, the depth bar is fixed to the center of the frame pipe. Therefore, the sowing unit could not be moved from side to side, which resulted in the problem that the position for fertilizing and sowing was restricted.

In this invention, the central part of the frame pipe is pivotally supported on the tractor side by a hitch, and both ends of the fertilization and seeding device are supported by mounting frames on both sides of the frame pipe, so that the installation position of the fertilization and seeding unit can be adjusted between them. By sliding the position of the mounting frame left and right, the mounting interval of the seeding units can be freely changed, and the number of fertilizing and seeding units can also be increased or decreased.

In addition, in order to enable the suppression roller, which also serves as the driving force extraction wheel of the fertilizing and seeding device, to also serve as a wheat treading roller, the fixed angle between the frame pipe and the mounting frame can be changed.

(d) Means to solve the problem In order to solve this problem, this invention
It is structured as follows.

The pipe portions 12a at the tips of the mounting frames 12L, 12R are fitted onto both left and right ends of the frame pipe 10, whose central portion is supported by a hitch 9 attached to the rear of the tractor, and fixed with pins. Attach the rear end to the side frame 23
A mounting bar 20 is attached to the front ends of the side frames 23L and 23R, overlapping with the rear end portions of the side frames 23L and 23R, and is pivoted by the rotating shaft 13a of the suppression roller 13. Attach several units in parallel, and attach the mounting bar 20 and mounting frame 1.

There is. Therefore, by rotating the variable angle handle 16, the distance between the mounting frame 12 and the side frame 23 is changed, and the groove making disk 39 and the soil covering disk 4, which will be described later, are changed.
The ground contact angle of 2 is changed.

Further, a rotating shaft 13a of the suppressing roller 13 is supported on the pivot parts of the mounting frames 12L, 12R and the side frames 23L, 23R, and a stay 2 is attached to the rear end.

The mounting bar 20 is fitted to 23a, and several fertilization and seeding units C are attached in parallel, allowing fertilization and sowing of several rows at the same time.

In addition, the fertilization and seeding unit C has hoppers 30F and 30F in the front and back so that fertilization and seeding can be performed simultaneously.
R, feeding device 31F, 31R, guide pipe 3
2F and 32R are provided, and a mounting member 33 is fixedly provided at the front end of the feeding device 31F and is fitted into the mounting bar 20. A support post 3 is provided at the front lower part of the mounting member 33.
8 is erected, and two V-shaped disk-shaped groove forming disks 39 are pivotally supported at the lower end.
The seeds are fertilized and sown inside and outside. 40 is a scraper. Further, a seeding frame 36 is pivotally connected to both sides of the lower part of the mounting member 33 via parallel links 34 and 35 so as to be able to swing up and down, and a link spring 37 is interposed between diagonal pivot pins. A shaft 41 protrudes from the side surface of the seeding frame 36, and a soil covering disk 42 is disposed at the lower end of the shaft 41.

(f) Function of the device With this configuration, when changing the width of the pipe 13b of the compacting roller 13 when replacing the rotary tilling device attached to the tractor and increasing the tilling width, or when changing the width of the pipe 13b of the pressure roller 13, When increasing or decreasing C, tighten the bolts 2 on the mounting frames 12L and 12R.
2, remove the pin 19, the mounting bracket 17 of the mounting bar 20, the support collar 44, and the scraper 29, and then remove the mounting frame 12R and side frame 23R.
By removing the fertilizing/seeding unit C, you can increase or decrease the number of fertilizer/seeding units C, and by removing the side plate 13c of the pressure roller 13, the roller 13 can be increased or decreased.
b can also be exchanged. If the left and right balance is poor after replacement, either move the seeding unit on the mounting bar 20 or tighten the pin hole 10 of the frame pipe 10.
All you have to do is change the position of b.

Furthermore, as shown in FIG. 6, by inserting the insertion holes of the pins 19 of the pipe portion 12a into the frame pipe 10 at different angles, it is possible to create a state in which only the pressure roller 13 is in contact with the ground. This allows it to work as a barley tread roller.

(G) Effects of the invention Due to the above-described structure and operation, the present invention has the following effects.

Since it is configured as described in the scope of the utility model registration claim 1, it is easy to replace and increase/decrease the fertilizing and seeding unit C, it is also easy to change the width of the pressure roller, and the tilling width of the rotary tilling device attached to the tractor can be changed. It is now possible to respond by accurately changing the width of the fertilizer and seeding machine when the number of rows of crops or the width of rows in the field changes.

Since the structure is as set forth in claim 2 of the utility model registration, by changing the angle of the mounting frames 12L and 12R with respect to the frame pipe 10, a state in which only the pressure roller 13 is in contact with the ground can be created, and the wheat treading work can be performed. It became possible.
