Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a structure in which a chain case that drives a pressure roller of a fertilizing and seeding machine can be attached and detached integrally.

(b) Prior art A fertilizing seeding machine consisting of several seeding units arranged in parallel is configured so that each seeding unit is integrally driven through a single drive shaft. The structure was such that one end of the drive shaft was passed through the front part of the chain case and the chain sprocket was directly attached to it, and the rotating shaft of the suppression roller was also passed through the rear part of the chain case and the chain sprocket was directly attached to it. It is.

Therefore, it was difficult to assemble.

(c) Problems to be solved by the invention However, as mentioned above, in the conventional technology, there are many problems such as when attaching and detaching the pressure roller section from the fertilization and seeding machine A, inspection and maintenance of each part of the fertilization and seeding machine A and the pressure roller section, and parts. When replacing it, it was necessary to disassemble the chain case, which was made up of two pieces.

Disassembling the chain case required removing a considerable number of bolts and nuts, which required time and effort, and subsequent assembly was not easy.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

In a fertilization seeding machine equipped with a seeding unit at the front and a compression roller at the rear, the input sprocket shaft at the front end of the chain case is connected to the input sprocket shaft at the front end of the chain case so that the chain case that transmits the power of the compression roller to each seeding unit can be attached and removed as a whole. The purpose of this design was to fit onto the drive shaft of the unit, and also to insert the protruding end of the output sprocket shaft at the rear of the chain case into the rotating shaft of the pressure roller.

(E) Embodiment The purpose of the present invention is as described above, and next, the configuration for achieving the purpose will be explained.

First, let me explain the attached drawings.

4 to 7 are perspective views showing the assembly process of the fertilizing and seeding machine A, FIG. 8 is a sectional view of the rear part of the pressure roller and the chain case, and FIG. 9 is a plan sectional view of the front part of the chain case.

First, the overall configuration of the fertilizing and seeding machine A of the present invention will be explained based on FIGS. 1 and 2.

The fertilizing and seeding machine A of the present invention has a plurality of seeding units C... located in parallel, and a groove-making disk 1 made of two disks stacked in an inverted V shape at the lower front of the seeding unit C... A soil covering disk 2 is located behind the seeding unit C.

The fertilizing and seeding machine A of the present invention is attached to the rear end of the rotary tiller B attached to the rear of the tractor.

Furthermore, a long cylindrical pressure roller 3 is located between the left and right sides at the rear end of the fertilization seeding machine A, and as the tractor moves forward, the pressure roller 3 rotates when compacting the soil surface, and this rotational force is transferred to the chain case 25. The information is transmitted to each seeding unit C through the seeding unit C.

Next, based on FIGS. 1 to 8, the detailed structure of the fertilizing and seeding machine A of the present invention and the method of attaching the fertilizing and seeding machine A to the rotary tiller B will be explained in order.

The rotary tillage device B includes a chain case 4,
It is composed of a tilling cover 5, a tilling claw 6, a rear cover 7, a main support 8, an adjustment handle 9, etc., and has depth frames 10, 10 protruding rearward from both sides of the gearbox of the rotary tilling device A. Depth bar 11 at the rear end of
is placed horizontally.

The pressure roller 3 on the side of the fertilizing and seeding machine A is composed of a cylindrical resin pipe long in the left and right direction, and disc-shaped side plates 12, 12 are provided at the left and right openings of the pressure roller 3.
It has been closed. Pipe-shaped rotating shafts 13, 13 are projected outward from the axes of the side plates 12, 12, respectively, and the rotating shafts 13, 13 are mounted on the rear ends of left and right mounting frames 14, 14. 1
5 and 15, the entire pressure roller 3 is supported.

16, 16 are bearing metals provided within the bearings 15, 15.

The bases of stays 18, 18 are attached to the rear ends of the left and right mounting frames 14, 14, respectively, and a scraper 19 is attached between the stays 18, 18 at the rear of the pressing roller 3.

Ends of laterally long pipes 20, 20 are attached to the front ends of the left and right mounting frames 14, 14, respectively, and the pipes 20, 20 are attached to the pipe frame 2.
By fitting the pressure roller 3 into the pipe frame 21, the pressure roller 3 can be supported by the pipe frame 21.

22, 22 are locking pins for locking the pipes 20, 20 to the pipe frame 21. Note that the pipe frame 21 has a plurality of pin holes 2 in the left and right direction.
1a... are provided so that when the left and right length of the pressure roller 3 is changed in accordance with the number of seeding units C..., the positions of the mounting frames 21, 21 can be changed accordingly.

Then, as shown in FIGS. 3 and 4, the pivot 22 provided in the center of the pipe frame 21 and the rear end of the hitch 23 are pivotally connected with a pin 23, and the hitch 23 is attached to the rear end of the rotary tiller B. Depth bar 1
By locking the central part of 1, the pressure roller 3
The whole is supported by a rotary tiller B. 24, 24 are fixing pins of the hitch 23.

Subsequently, as shown in FIGS. 3, 5, and 8,
The end of the right rotation shaft 13 passes through a hole at the rear end of the side frame 16 and is locked with a pin 17 to prevent it from coming off.

Since the end of the left rotation shaft 13 is made of a pipe, insert the end of the output sprocket shaft 26 that protrudes from the rear end of the chain case 25.
By locking with the pin 27, the chain case 25 can be easily attached to the pressure roller 3 side.

Next, as shown in FIGS. 3, 6, and 7,
Front end of side frame 16 and chain case 2
The mounting bar 28 is supported and fixed by the U-shaped mounting brackets 26, 16a and the stays 27, 27 which are fixed and attached to the front end of the bar 5. A plurality of seeding units C are installed between the left and right mounting frames 14, 14.
... are arranged and fixed to the mounting bar 28.

Next, one drive shaft 29 having a square or hexagonal shape is connected to the feeding section 3 of each seeding unit C.
1, and the feeding portions in each seeding unit C can be interlocked by this drive shaft 29.

Furthermore, as shown in FIGS. 3, 8 and 9,
An input sprocket shaft 30 is built into the front end of the chain case 25, and the input sprocket shaft 30 has a square fitting hole that matches the outer shape of the drive shaft 29. The drive shaft 29 is passed through the input sprocket shaft 30 and locked with a pin 43. This makes it possible to easily attach the chain case 25 without disassembling it.

Note that screw bodies 33, 33 are interposed between the front ends of the stays 27, 27 and pins 32, 32 supported by the left and right mounting frames 21, 21.
By rotating 3, 33 with angle-changing handles 34, 34 at the upper end, the position of the seeding units C can be changed and the depth of seeding can be adjusted.

As described above, the chain case 25 is designed so that it can be directly assembled into the fertilizing/seeding machine A without disassembling the input sprocket shaft 30, the output sprocket shaft 26, the sprockets 40, 41, and the chain 42 inside. Furthermore, when removing the chain case 25, the chain case 25 can be removed directly and easily without disassembling the chain case 25.

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

First, since the chain case is independent and integrally constructed, it can be easily incorporated into the fertilizing and seeding machine without disassembling the chain case.

Secondly, contrary to the above, it was possible to easily remove the chain case from the fertilizing and seeding machine A without disassembling it.

Third, since the chain case can be easily attached and detached, inspection, maintenance, and assembly of the fertilizing and seeding machine A can be carried out easily and safely.
