Description

[Detailed description of the invention] <**Above field of application> The present invention 11ff relates to a grass harvesting device that gathers grass while cutting it ◎ Prior art> [Generally, the grass harvesting device 1rr, the belly of a traveling vehicle body Chobe Mata r
jIt is constructed so that while the mower installed at the front cuts the grass pipe, the grass is melted through a blower and stored in the grass collection box installed at the rear, and the grass collection box feeds the grass clippings. In order to separate and discharge the air, a portion or the whole of the tube is formed of a wire mesh or punched mesh IV or the like.

Problems that Kukaimei is trying to solve〉 If the grass collection box is vented in this way by forming the surrounding wall with a life line, etc., it is possible to prevent the discharge of grass clippings, but the mesh is large and thin The discharge of dust cannot be prevented, and dust 9 is generated during drying, which may make work difficult.

Means for Solving the Problems and Points> The present invention solves the problem of the prior art by using a grass collection box O.
This problem is solved by providing a screen at the wind outlet of η and providing a dust collector @4 on the leeward side of the screen.

In other words, the specific configuration of the problem solving means in Zero Hatsu 11 is as follows:
A mower 110+ and a grass collection box 1-* are attached to the running vehicle body, and the mowed grass collected by the mower □- is configured so that it can be stored in the grass collection box g through the grass transport device 4. In the device, the 12BK screen fin t-
□, the dust collection mechanism is placed on the leeward side of this wind relief row.

Function: The wind that carries the grass clippings from the mower (1α) is sent into the grass collection box, where the grass clippings are separated.Thin grass clippings are also separated by the screen box at the wind outlet ω.The screen box passes through. The remaining air passes through the duct C13t and is sent to the collection mechanism on the leeward side, where it undergoes a second separation action and most of the contained dust is separated and discharged from here as clean air. Ru.

<Example> Hereinafter, embodiments of the tree@aki will be described based on the drawings.

In Figures 1 to 3, (1) is a tractor as a traveling vehicle body, which has front wheels (21 and rear wheels: 31t'', left rear wheel 7
A floor seat (5) integrally having an entrance (41), a seat (61) and a steering device (f) provided on the upper part thereof
It has a 171st class meeting.

1101t! The mower is installed through the suspension mechanism 81SK under the belly of the traveling vehicle body 11+, and can travel while following the unevenness of the ground (Ll). The cutter +121 is arranged to be rotatable, and the cutter +121 is configured to be able to cut all the grass and release the cut grass to a mower deck (an example of a discharge port) using a drafting board.

(The power is a grass collection box installed at the rear of the traveling vehicle body + 11,
Boards are fixed to a box-shaped seven-frame frame made of pipes or rods to form a circumference of one square inch.

This grass collection box α and the mower 11O) are connected at the end of the blower device. 2D is the propeller, ri is the engine for driving the propeller, and these are located at the rear of the vehicle body +1) or at the rear of the vehicle body.
ll: It can be attached to the step part of the t70 seat (5), etc. In the example, the mounting base fixed to the vehicle body + 111c (
(not shown) and placed on the side of the grass collecting box Qη.

The idler side of the blower (211) is connected to the mower deck (river outlet a) through the hose and duct (toward), and is capable of suctioning the grass cut by the mower (101). The discharge side is connected to the upper part of the grass collection box ση via a bellows hose 4, and grass clippings can be discharged into the grass collection box (lη).

Grass collection box (17 It - To be more specific, the bottom of the grass collection box α is formed in a V shape, and the front sloped surface is equipped with a pocket) 2131, and the rear sloped surface is located halfway up the back wall. The opening/closing IE'll[1 extends to t'L.

The bracket protrudes forward and is fixed to a mounting base fixed to the vehicle body.

The opening/closing mechanism of the carcass closing mechanism is operable from seat 161. The lever circle is pivoted to the part of the grass collection box σ, and is linked to the FM opening/closing r3tA through the fixed arm circle and link 17, and the lever circle is rotated in the arrow direction (N direction). By operating the lid, it is possible to remove the grass stored in the container. It is preferable that the opening/closing mechanism is provided with a locking means to prevent the lever ring from being turned inadvertently.

5. The grass collecting box is divided into two parts at the top, and the height of the upper part is adjustable. That is, the frame edge is the first
．． As shown in Figure 3, upper F(l&)(181))
It is divided into composed of n
, the height of the upper part (1&) can be changed by arbitrarily selecting the bottle hole Mi of the square bar through which the stopper bottle 4 is inserted. Although the surrounding H1 is not shown, the upper part (1
8a) and the lower part (18b), a large plate material T- is provided,
They are slidably overlapped at an intermediate position.

Grass collection box a7)
The capacity of the 71 can be increased to accommodate a large amount of grass, and the upper limit height can be lowered in areas with obstacles, making it easier to work under tree branches. .

Moreover, it can be packed and stored compactly.

An example of a grass collecting box Oη is formed with a wind vent in the upper corner, and a screen box made of wire mesh or punched metal is provided at the wind vent.
This allows only the wind to discharge while completely preventing the outflow of grass clippings. A duct covering this wind outlet is installed on the side of the grass collection box ση9, and this duct has a wind outflow resistance In order to reduce the amount of paper, the top is wide and the shape tapers downward. A dust collector is arranged below the duct opening.

Dust collector 134! This is a centrifugal separator that has a circular inner cylinder inside a circular outer cylinder and a wind guiding member.It separates fine dust from the air that passes through the screen frame, releases the purified air downward from the inner mold, and removes the dust. It is constructed such that it can be taken out from the discharge port. Incidentally, as the dust collector, it is possible to use a type of centrifugal separator that uses a foil element.

The duct '331 and the waste collector rMJ#'17 are attached to the upper part (18a) of the frame frame (1B).
Even if the height of a) is changed, it is configured to follow it.

Fig. 84 shows a modified example of the duct and dust collector, in which the lower part of the duct opening is formed into two prongs, and a dust collector is arranged in each, thereby doubling the dust collection processing capacity. In FIG. 4, the upper and lower ends of the frame are integrally formed.

<Effect of light> According to the nine inventions detailed above, the wind release of the grass collection box 012
A screen frame is provided at 61, and a dust collector is installed on the leeward side of the screen.
This allows finer dust to be separated from the wind after grass clippings have been separated, reducing the amount of dust that was previously discharged.
Because it is dusty, there is less dust generation, even in dry conditions.
Mowing and collecting grass becomes easier.
