Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hem branch lifting guide that is useful for use in agriculture and horticulture, particularly in a fertilizer spreading device for managing brown furrows.

[Conventional technology and problems]

In order to spread fertilizer near the roots of crops planted in ridges, between the front and rear wheels, the fertilizer discharged from the outlet at the bottom of the hopper is centrifugally thrown around by the lower disk-shaped spreading blades. Fertilizer spreading equipment is becoming more popular, but if the crop itself is drooping or has overhanging branches at the base, it can get caught on them or hit them, making it impossible to reach the roots. Fertilization may not be as effective as expected.

In particular, in tea ridges, the tea plants are formed into a fan-shaped cross section, and the foot branches are overhanging and densely packed, so much of the fertilizer gets caught on the foot branches. For this reason, after applying the fertilizer, the farmers were forced to go back and forth between the furrows and hit it with a stick to remove the stuck fertilizer twice.

[Purpose of the invention] The present invention was developed in view of the current situation, and it secures a centrifugal throwing path for the fertilizer by lifting it up as the machine moves forward, starting from the base branch where the fertilizer is to be spread. The aim is to ensure that fertilizer is spread near the roots.

[Summary of the idea]

Therefore, in order to achieve the above object, the present invention is a fertilizer spreading method in which the fertilizer discharged from the outlet at the bottom of the hopper is centrifugally thrown around by the lower disc-shaped spreading blades between the front and rear wheels. The device is characterized in that it is a hem branch lifting guide for a fertilizer spreading device, which is formed by attaching a thin plate in a raised and flared shape from the vicinity of the front wheels to the vicinity of the rear wheels on the side.

〔Example〕

Next, an embodiment to which the present invention is applied will be described based on the drawings.

Reference numeral 1 is a so-called self-propelled fertilizer spreading device, which has a frame member 3 with a handle 2 projecting rearward and upward, a hopper 4 for storing fertilizer, and, for example, one front wheel 5 and two rear wheels. driving wheel 6
and a drive system 8 including an engine 7 serving as a drive source are combined to form the backbone of the device.

The hopper 4 is attached to the frame member 3 so as to be fitted therein, and has a shape that opens upward, with the upper part serving as an input port for fertilizer, and the lower part thereof having a discharge port. It is.

A conventional shutter is provided on the lower surface of this outlet, and can be opened by operating a lever 9 attached to the handle 2. Note that an adjustment plate for adjusting the opening area of the discharge port is appropriately attached to overlap this shutter.

Furthermore, stirring blades 10 are provided inside the bottom of the hopper 4 and directly above the discharge port, thereby making it easier to discharge the fertilizer stored in the hopper 4 from below.

Further, on the opposite side of the stirring blade 10 across the discharge port, that is, on the outside of the bottom of the hopper 4, a disc-shaped dispersing blade 11 is provided.

These stirring blades 10 and dispersing blades 11
is rotatably driven together with the rear drive wheels 6 by a drive system 8 of an appropriate type.

Further, 12 is a cover that covers the side of the drive unit,
Other appropriate necessary members such as a clutch are attached.

Reference numeral 13 denotes a guide mounting rod bent into a U-shape, and a mounting piece 13 on the inside of the tip is attached to the shaft attachment portion 3a of the front wheel 5.
a are attached coaxially, and both other ends 13b are attached to the cover 12 of the drive section. and,
On both sides of the mounting rod 13, that is, on both sides of the fuselage, from the vicinity of the front wheel 5 to the vicinity of the rear drive wheel 6, a hem branch is cut in a peripheral curve in a bulging shape toward the rear and a flare shape toward the lower side. Fix the lifting guide 14.

This foot branch lifting guide 14 is made of a thin aluminum plate or a resin plate.

In such an embodiment device, the fertilizer spreading operation is performed as follows.

First, fertilizer is filled into the hopper 4 according to the usual method, and then the engine 7 is started and the engine 7 is driven to a predetermined position. When the area where the fertilizer is to be sprayed is reached, the lever 9 on the handle 2 is used to operate the shutter.
This is done by holding the shutter and moving the shutter to open the discharge port and allow the fertilizer to fall from there.

Then, the rotating spreading blades 11 centrifugally scatter the falling fertilizer into the surrounding area.

Conventionally, the hem branches did not reach near the base or got caught on the hem branches, but according to the device of this embodiment, the hem branch lifting guide 14 sequentially lifts the hem branches upward as the aircraft advances. It sweeps through the bottom branches to ensure a centrifugal discharge path for the fertilizer, so the centrifugally discharged fertilizer is reliably spread to the vicinity of the roots without falling or getting caught on the way. Become.

The present invention has the above-described configuration, and in this embodiment, the most preferable one has been cited as an example, but it goes without saying that the fertilizer spreading device is not limited to that of this embodiment.
For example, it may be an electric type that uses a battery or the like as an energy source instead of an engine, it may be a push type device that does not drive wheels, it may be a single wheel type in the front and rear, or it may be of any other appropriate type. Things can be chosen. Furthermore, it can be applied to any suitable known fertilizer spreading device, such as one that does not have stirring blades.

[Effect of idea]

The present invention has the above-mentioned configuration, and as the machine advances, the bottom branches are sequentially lifted and swept away from the point where the fertilizer is to be spread, thereby ensuring a centrifugal throwing path for the fertilizer and ensuring a reliable flow. Fertilizer can be applied near the roots of crops.
