Description

[Detailed description of the invention] (a) Industrial application field The present invention is a device for a fertilizer spreader for a management machine that is attached to the side of the management machine.

(b) Prior Art Fertilizer spreaders that are directly attached to the management machine have existed in the past, and the structure was such that the fertilizer spreader was attached only to the rear hitch at the rear end of the management machine.

(c) Problems to be solved by the invention However, conventional fertilizer spreaders had the following problems.

Firstly, because the fertilizer spreader was attached only to the rear hitch of the management machine, the fertilizer spreader itself was very difficult to operate, especially when working with a full load of fertilizer in the fertilizer hopper or when changing the direction of travel. Because of their heavy weight, it was common for twisting and distortion to occur at the parts where they were attached to the axles and management machines. Furthermore, when mounted on the rear of a fertilizer spreader, the overall length of the fertilizer spreader and the fertilizer spreader became longer, requiring a wider headland for turning.

Second, as a result of the above, sufficient traction force could not be obtained, the size of the fertilizer spreader itself was limited, and the footwells were narrow, making it difficult to operate and operating, resulting in many dissatisfaction with performance.

The present invention solves the above-mentioned problems.

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

Fertilizer hopper 1, which is configured to be long in the horizontal direction, is attached to the front and rear of management machine B at the front end and rear end of one side, and a front wheel 5 is installed in front, and one axle 19R of management machine B is attached to the hopper 1. It extends to the other end, making the space between the drive wheels 6L and 6R wide.

(e) Embodiment The object and configuration of the present invention are as described above. Next, the configuration of the embodiment shown in the attached drawings will be explained.

It is a front sectional view of the axle part in a figure.

The fertilizer spreader A of the present invention is attached to the side of the management machine B, as shown in Figures 1 to 3.
This is a working machine that spreads the fertilizer filled in the hopper 1 of the fertilizer spreader A onto a field while traveling.

The fertilizer spreader A that constitutes the present invention is roughly divided into a hopper 1, a main frame 2, a front mounting frame 3, a rear mounting frame 4, a front wheel 5, left and right drive wheels 6L and 6R, an extension axle 7 and a spreading drive section. It can be divided into C.

Next, each of these parts will be explained in detail.

As shown in FIGS. 1 to 5, the hopper 1 has a triangular shape when viewed from the side and an elongated shape when viewed from above, and is filled with fertilizer to be spread.
For this purpose, a plurality of openings 1a are provided on the bottom surface of the hopper 1 from left to right to release the fertilizer.

The hopper 1 has a shape that greatly protrudes from the front, and its center of gravity is located between the front wheel 5 and the driving wheels 6L and 6R, thereby making the fertilizer spreader A as a whole stable.

The main frame 3 is, as shown in FIGS. 1 to 5,
It has a long shape in the front and back direction, and is fixed to one of the left and right side plates 9L and 9R of the hopper.

The front mounting frame 3 has an inverted L shape when viewed from the side, as shown in FIGS. 1 to 5 and FIGS. 7 and 8. The base of the front mounting frame 5 is fixed to the front side surface of the main frame 2, and has a bolt hole 3a at its end.

Therefore, with one bolt 12, the front mounting frame 3 can be attached to the front hitch 11 at the front end of the frame 10 of the management machine B.

The rear mounting frame 4 has an L-shape when viewed from the side, as shown in FIGS. 1 to 5 and FIGS. 9 and 10. The base of the rear mounting frame 4 is fixed to the rear side surface of the main frame 2, and the mounting plate 1 has an inverted L shape when viewed from the side in front of the end.
3 is fixed to the mounting plate 13, and the upper surface of the mounting plate 13 has a bolt hole 13a. Therefore, with one bolt 14, the mounting plate 13 at the end of the rear mounting frame 4 can be mounted to the rear hitch 15 at the rear end of the management machine B.

In this way, the rear of fertilizer spreader A is also controlled by machine B.
Since it is attached to the rear of the vehicle, it can be installed more firmly than before, and has sufficient traction force. This makes it possible to sufficiently withstand even when a large fertilizer spreader A is mounted.

In the past, if the fertilizer spreader A was attached only to the front hitch 11, it would be too far forward, resulting in poor weight balance and difficulty in driving, and attaching a large work device to the front hitch 7 of the main body would be difficult. It was also impossible.

However, as in the present invention, by connecting and attaching the fertilizer spreader A to the front and rear hits 11 and 15 of the management machine B, and by using the front mounting frame 3 and the rear mounting frame 4, the fertilizer spreader A can be attached to the side of the management machine B. By equipping it, it was possible to increase the legroom for the worker who operates the control machine B, and the operation became safer.

Also, when steering and turning, the management machine B
Raise the handles 16L and 16R of the fertilizer spreader A.
Rather than lifting the front part of the handle 16L, 16
It is easier to operate the fertilizer spreader A by lowering R and lifting the front part of the fertilizer spreader A.

The front wheel 5 is located below the front end of the fertilizer spreader A, as shown in FIGS.
It is attached to a.

As shown in FIGS. That is, the extension axle 7 is supported by bearings such as pillow blocks attached to the lower end rear parts of the left and right side plates 9L and 9R of the fertilizer spreader A, and both ends of the extension axle 7 are connected to the left and right side plates 9L and 9R.
It is made to protrude from 9R.

Note that axles 19L and 19R protrude from both sides of the lower end of the transmission case 18 of the management machine B, and a drive wheel 6L is attached to the left axle 19L. Connecting member 2 is attached to the right axle 19R of these.
Attach one end of the extension axle 7 to the axle 1 through the
It was made to look like 9R was extended. 22 is a locking pin.

Then, the left drive wheel 6R was attached to the other end of the extended axle 7. Therefore, the distance between the drive wheels 6L and 6R is widened, improving the stability of the fertilizer spreader A.

The spreading drive section C automatically spreads the fertilizer in the hopper 1, and its configuration is as shown in FIGS. 1 to 5. In other words, the left and right side plates 9 of the hopper 1
The shaft 23 supported by L and 9R is the hopper 1
It is located between the left and right sides near the bottom of the shaft 23, and a large number of fertilizer discharge rotors 24 are attached to the left and right sides of the shaft 23. This fertilizer release rotating body 24...
The fertilizer is spread from the opening at the bottom of the hopper 1 by rotating the hopper 1, and the rotational power is taken in from the extended axle 7. For this purpose, the extension axle 7 and the shaft 23 are equipped with gears 25, 2.
6 is installed, and chain 2 is installed between these gears.
7 is multiplied.

In addition, as shown in FIG. 11, the rotational power of the front wheel 5 is transmitted to the shaft 23 through the chain 26 to rotate the fertilizer discharge rotary body 24, and as shown in FIG. From the PTO shaft 29 protruding from the upper side of the case 18, the fertilizer discharge rotary body 24 is connected via a transmission belt 28 or a chain, etc.
It is also possible to adopt a configuration in which power is introduced into the system.

Furthermore, as shown in FIGS. 13 and 14, a shaft 23 is attached to the end of the axle 19R protruding from the transmission case 18.
The ends are directly connected, and the drive wheel 6R is connected to the other end of the shaft 23.
It is also possible to have a configuration in which the

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

First, the fertilizer spreader is installed in front of and behind the management machine, so even when working with a full load of fertilizer in the fertilizer hopper or changing the direction of travel, the fertilizer spreader can be mounted on the extended fertilizer spreader side. It was possible to eliminate twisting and distortion that occurs in the axle and the mounting part of the management machine, and it was possible to achieve a stable weight balance.

Secondly, as a result of the above, it was possible to provide sufficient traction force to the fertilizer spreader itself, and the fertilizer spreader itself could be operated safely and easily regardless of its size.

Third, the fertilizer spreader can be easily attached to the management machine by attaching one bolt to each of the front and rear hitches, making it easy to attach and detach. be.

Fourth, if the fertilizer spreader is attached only to the rear hitch and moves forward, the torque of the axle will be applied to the fertilizer spreader, increasing the working resistance and reducing the traction force.However, if the fertilizer spreader is attached to the side front side as in the present invention, The forward torque of the drive wheels works to lift the fertilizer spreader, reducing working resistance, and conversely, preventing the drive wheels from slipping due to weight being added to the management machine body, increasing the forward force. Become. Therefore, the performance will be dramatically improved compared to before, and the applications of the management machine will be greatly expanded.

Fifth, depending on the horizontal length of the fertilizer hopper,
Since the distance between vehicles can be adjusted accordingly, it is possible to adapt to the change to a hopper of any size.

Sixth, the axle of the management machine is connected to the extension shaft of the fertilizer spreader, and a drive wheel is attached to the end of the axle, making it look like an extension of the axle, which increases the width between the drive wheels and provides stability. This allows you to drive with ease.
