Abstract

PURPOSE:To properly cut standing grasses and surely discharge the cut grasses from the vehicle by guiding grasses cut with a rotary blade toward the lateral side of the grass with a cover placed above the blade and placing a plurality of longitudinal slit grooves arranged parallelly in lateral direction above the rotary blade. CONSTITUTION:The over 3B of a mower 3 is formed in a state divided into a front cover part K1 and a main body part K2. A plurality of slit grooves S are arranged parallelly along lateral direction on the part K1 and are directed in vertical direction in front of the rotary blade 3A and in longitudinal direction above the blade 3A. Grasses cut with the blade 3A is guided and transferred toward the side of the vehicle with a guiding cover W placed above the rotary blade 3A.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mowing operation in which grass in a standing position is introduced into a cutting action section on the front side of a rotary blade body in a standing position. About cars.

[Conventional technology]

The above-mentioned mowing vehicle can handle tall grass in a standing position.
It can be introduced into the cutting action section on the front side of the rotary blade body to achieve good cutting.

However, conventionally, no special measures have been taken to discharge grass cut by the rotary blade.

For example, when an engine is mounted above the rotary blade, the engine pushes and discharges cut grass to the outside of the vehicle body.

[Problem to be solved by the invention]

Conventional mowing vehicles have the disadvantage that cut grass adheres to various parts of the vehicle body during mowing work.

Particularly when the engine is mounted above the rotary blade, there is a risk that the cut grass may adhere to the engine and be heated and burned.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to eliminate the above-mentioned disadvantages by simple modification.

[Means to solve the problem]

A feature of the present invention is a mowing vehicle configured such that grass in a standing position is introduced into a cutting section on the front side of a rotary blade in a standing position, the grass being cut by the rotary blade. A guide cover that guides the grass that has been removed towards the side of the vehicle body.
The point is that it is provided above the rotary blade body.

In order to introduce grass in a standing position into the cutting action section on the front side of the rotary blade body, the following configuration is preferable.

A cover body is provided to cover the upper part and the entire lateral circumference of the rotary blade body to improve safety. Above the rotary blade body, a plurality of slit grooves extending in the front-rear direction may be formed side by side in the width direction.

[For production]

The effects of the above features are as follows.

That is, the cut grass is guided and moved laterally to the vehicle body by the guide cover, and is accurately discharged to the outside of the vehicle body.

In addition, when covering the upper part and all sides of the rotary blade body with a cover body, if a slit groove is formed in the front part of the cover body, the slit groove can cut tall grass. It will be introduced into the action part.

Although the cover body has slit grooves formed therein, it exhibits the function of preventing other objects from coming into contact with the rotary blade body and the function of preventing pebbles and the like from scattering to the outside.

[Effect of idea]

The effects according to claim 1 of the present invention are as follows.

That is, the cut grass can be guided and moved laterally to the vehicle body by the guiding action of the guide cover, and can be accurately discharged to the outside of the vehicle body, thereby eliminating the inconvenience of cut grass adhering to and accumulating on various parts of the vehicle body. Therefore, the - layer can be used satisfactorily.

The effects of claim 2 are as follows.

Tall grass can also be introduced into the cutting area of the rotary blade so that it can be cut properly while preventing other objects from coming into contact with the rotary blade or stones etc. from scattering to the outside. ,
This allows for good and safe work to be carried out.

〔Example〕

Hereinafter, a case where the present invention is applied to a remotely controlled mowing vehicle will be explained based on the drawings.

As shown in Figs. 1 and 2, the mowing vehicle has a pair of left and right front wheels (1), a pair of left and right rear wheels (2), and a mower (
3) and an engine (4) as the main parts.

The front wheels (1) are reoriented about a longitudinal axis for steering, and the rear wheels (2) are driven for propulsion. Also, front and rear wheels (1).

(2) consists of a disc-shaped wheel part (a), a cylindrical ground contact part (h), and spikes (C) installed in a staggered manner on the ground contact part (b). It is now possible to drive accurately. However, the rear wheels (2
) has a larger diameter and width than the front wheel (1).

The mower (3) includes a rotary blade (3A) that is driven and rotated around a vertical axis, and a cover body (3B) that covers the entire upper and lateral circumference of the rotary blade (3A).

As clearly shown in FIG. 2, the engine (4) is mounted on the upper part of the vehicle body frame (F), a transmission case (M) for rear wheel drive is connected to the rear part of the vehicle body frame (F), and the vehicle body A front wheel support frame (5) is attached to the front part of the frame (F) so as to be swingable around an axis along the front-rear direction.

An explanation will be added regarding the mower (3).

The cover body (3B) is divided into a front cover portion (K1) and a main body portion (K2). Main body part (K
2) is an upper cover part (made of a rigid plate member).
6) and a rubber side cover part (7), which is attached to the seat frame (F) with bolts.

The front cover portion (K1) extends along the up and down direction in front of the rotary blade body (3A) and extends along the vertical direction in front of the rotary blade body (3A).
), a plurality of slit grooves (S) extending in the front-rear direction are lined up in the width direction, and are detachably connected to the main body portion (K2) with bolts. With this configuration, grass in a standing posture is introduced into the cutting action section on the front side of the rotary blade (3A) in a standing posture.

As shown in Fig. 3, bolt insertion holes (9) are formed on both sides of the main body part (K2) for mounting the balance weights (8), so that they can be used when working on slopes, etc. If necessary, a balance weight (6) can be attached to one side of both sides of the vehicle body.

As shown in FIGS. 1 and 2, a guide cover (VO) guides and moves grass cut by the rotary blade (3A) toward the side of the vehicle body. ) is bolted to the main body portion (K2). This guide cover (IQ) basically has a shape in which the rear side protrudes laterally outward, and the upper side is located inwardly within the vehicle body.

In addition, (10) in Fig. 4 shows the rear wheel drive transmission case 0.
This is a cylindrical axle cover that covers the axle (8) supported by the transmission case 0.1), and is bolted to the side surface of the transmission case 0.1).

Although not described in detail, the vehicle body is equipped with a remote control controller, so that steering operations and forward/reverse switching operations can be controlled remotely.

[Another example]

In carrying out the present invention, the auxiliary guide cover is provided so as to be switchable between a position in which the grass is guided to the left side of the vehicle body and a position in which it is guided to the right side of the vehicle body, so that the grass is guided to the left and right sides of the vehicle body. You can do it like this.

As described in the above embodiment, the cover body (3B) is divided into the front cover part (K1) and the main body part (K2), and the front cover part (K1) can be attached to and detached from the main body part (K2). Of course, instead of doing so, the entire cover body (3B) may be integrally formed.

The mower of the present invention can be applied not only to remotely controlled mowing vehicles, but also to ride-on and walkable mowing vehicles. In addition, the configuration of each part necessary for carrying out the present invention can be changed in various ways.

Incidentally, although reference numerals are written in the claims section for convenience of reference to the drawings, the present invention is not limited to the structure shown in the accompanying drawings by such entry.
