Abstract

PURPOSE:To prevent the stagnation of solid materials in a blower and the breakage of the fan and an outer circumferential wall by providing an outer circumferential wall of a blower fan with a discharging mechanism to discharge the solid materials mixed in the transporting mowed grass from the blower. CONSTITUTION:An outer circumferential wall 3 of the fan of a blower 2 is provided with a discharging port 16 of a discharging mechanism 4. A swingable discharge guide plate 19 is attached to the upper side of the discharging port 16 to close the port with the plate by the force of a spring 20. Solid materials in the mowed grass are applied with large centrifugal force and exclusively passed through the discharging port 16, guided by a discharge guiding plate 19 and discharged from the outer circumferential wall 3 of the fan.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a grass clippings transfer device for a lawn mower.

Prior Art and Problems to be Solved by the Invention In a grass mower equipped with a blower that transfers grass clippings cut by a mowing device using wind pressure, a piece of stone, golf pole, etc. These solids may be sucked into the blower together with the grass clippings and become stagnant inside the blower, so the stagnant solids may be sucked into the fan inside the blower, the outer peripheral wall, etc. There is a risk of damage to the fan, outer peripheral wall, etc. due to collision with the fan.

Means for Solving the Problems The present invention includes a method in which solid matter to be mixed into the grass clippings being transferred is placed on the fan outer peripheral wall (3) of the blower (2) that transfers the grass clippings cut by the cutting device a (1) under wind pressure. The mower's grass clippings transfer device is provided with a discharge mechanism (4) that automatically discharges the grass to the outside of the blower (2).

Effects of the Invention The grass clippings cut by the cutting device (1) are transferred by wind pressure by the blower (2), and the solid matter mixed in the grass clippings being transferred is transferred to the fan outer peripheral wall (3) of the blower (2). ) is automatically discharged to the outside of the blower (2) by a discharge mechanism (4) provided in the blower (2).

Effects of the Invention Due to this action, the solids do not stay in the blower as in the problem described above, so the solids do not stagnate in the blower (2).
) does not collide with the fan, the outer circumferential wall (3), etc., and therefore, damage to the fan, the outer circumferential wall (3), etc. is unlikely to occur.

Example On the side, (5) shows the running vehicle body, (6) the machine base, (7) a pair of left and right front wheels, (8) a pair of left and right rear wheels, and (9) a prime mover inside. Bonnet, (lO) is the steering wheel that steers the front wheels (7) (7), (11
) is the passenger's control handle.

FIJI between the front wheels (7) (7) and the rear wheels (8) (8)
Below the machine base (6), there is a cut grass outlet (1) at the right end.
A grass cutting device (1) is provided on the right side of the rear end of the machine base (6).
A blower (2) consisting of a transfer tube (14) having a transfer cylinder (14) and a case portion containing a fan (not shown) is provided between the suction port and the discharge port (12) of the blower (2). teeth,
A communication cylinder (!5) that communicates from the discharge port (12) to the suction port
) will be established.

A discharge mechanism (4) located near the lower end of the transfer cylinder (14) is provided on the fan outer peripheral wall ffl (3) of the blower (2).
A discharge port (IB) is provided, and a support member (
1? ) A support shaft (to) supported by (17) is provided,
A discharge guide plate (18) of the discharge mechanism (4) that covers the upper side of the discharge port (16) along the fan outer peripheral wall (3) is rotatably provided on this support shaft (18). On the support shaft (18), a discharge guide plate (18) is elastically biased in the direction of closing the discharge port (1B) with a discharge guide plate (18). 6), the spring (20) that can be guided by the discharge guide plate (19) and discharged to the outside of the fan outer peripheral wall (3) is sunk.

Note that arrow view (A) indicates the rotation direction of the fan within the blower (2).

Next, the effect will be explained. Grass cut by the mowing device (1) is sucked into the blower (2) through the discharge port (+2), the communication tube (15) and the suction port, and the grass clippings are sucked into the blower (2) by the blower (2) through the discharge port (+2), the communication tube (15) and the suction port. Therefore, it is discharged through the transfer tube (+4) and the discharge port (13).

The solid matter in the blower (2) that is mixed in with the grass clippings is removed by the spring (
20) and push open the discharge guide plate (19) to discharge r1 (1
8) and is guided by the discharge guide plate (19) and discharged to the outside and downward of the fan outer circumferential wall (3).

[Brief explanation of the drawing]

The figures show one embodiment of the present invention; FIG. 1 is a perspective view, and FIG. 2 is an overall perspective view. In the figure, symbol (1) is a reaping device, and symbol (2) is a blower. (3) shows the fan outer peripheral wall, and (4) shows the discharge mechanism.

Claims (1)

[Claims] The fan outer peripheral wall (3) of the blower (2), which transfers the grass clippings cut by the cutting device (1) under wind pressure, automatically moves solid matter to be mixed into the grass clippings being transferred to the outside of the blower (2). A grass clippings transfer device for a lawn mower, which is provided with a discharge mechanism (4) for discharging the grass.
