Description

[Detailed description of the invention] This invention relates to vertical protection for the engine of a weeding machine, etc., and its purpose is to protect the engine of the weeding machine, simple tiller, etc. from the ``mud'' that bounces backwards as the rotor rotates. The aim is to devise a vertical protection method that can be used to prevent people from getting infected.

Hereinafter, one embodiment of the present invention will be described in detail with reference to a diagram of a weeding machine for paddy fields. In the diagram, R denotes a rotor for weeding paddy fields, which is connected to the tip of a support pipe 2 via a worm box 3.

When using a simple tiller, the rotor is used for tilling.

Reference numeral 3a denotes a worm wheel fixed to the support shaft 1 of the U-tater R, and a transmission shaft (not shown) inserted into the support tube 2.

) It engages with the worm 4 fixed at the tip.

Reference numeral E denotes an engine connected to the rear end of the support tube 2, which rotates a rotor R for weeding rice fields via a worm 4, a form wheel 3a, and a support shaft 1 from a transmission shaft.

Reference numeral 5 denotes a joint fitting fastened to a part of the support tube 2, and a plate-shaped protective vertical plate 6 is diagonally attached to the upper part of the fitting so as to be removable and rotatable.

The housing handle 7 is fitted into the lower part of the joint fitting 5,
The nib portion 7a is fitted to the rear end of the handle T which is bent upward from below the engine E.

Note that the joint fitting 5 is connected via the support shaft 6a of the protective vertical 6.
On the other hand, it is attached in a removable and rotatable manner with ports 5a to 5a.

Reference numeral 6b denotes a mounting flange portion of the support shaft 6a, to which the protective vertical portion 6 is fixed.

Next, the operation buttons and effects of the vertical protection with the above configuration will be specifically explained.

Now, when weeding the rice field T using the paddy field weeding machine configured as in the above embodiment, an operator (not shown).

) gives the machine an appropriate inclination (see Figure 1).
When this operator holds the grip part Ta of the handle 7 and moves the machine forward in the direction of the arrow U, the above-described weeding work is performed.

In particular, if the vertical protection is installed diagonally on a part of the support pipe 2 as in this example, even if the weeding rotor R rotates and splashes the mud backwards, the vertical 6 prevents not only the engine E but also the front of the worker from getting dirty with mud.

In other words, the present invention is based on the configuration described in the claims for utility model registration, and the engine E at the rear of the machine is
This invention can be said to have a high practical value because it not only has a mud-repelling effect on workers, but also on workers.

Also, by making the cover rotatable, it is possible to slightly modify the direction of the "mud removal".

In other words, for a worker who deviates slightly to the left or right due to the operator's handle operation habit, the protection vertical 6 can be rotated in response to the worker's deviation.

In addition, by providing this protective vertical 6 in a removable manner,
When performing work that does not require a "mud guard", it is advantageous to remove this protective vertical 6 in advance.
