Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a grass discharge structure for a riding lawn mower.

The present invention relates to a lawn mower in which a work vehicle rides on the body of the machine to cut grass, etc., and in particular, the lawn mower is designed to distribute the grass cut by the cutting blade to the left and right sides of the machine body and send it to the rear of the machine body. Regarding grass discharge structure of lawn mower.

(b) Prior art Regarding conventional riding lawn mowers, see Japanese Patent Application Laid-Open No. 57-65124.
As stated in the publication, the cut grass is discharged outside the case by the rotation of the cutting blade and the forced air flow of the fan. Because it is difficult to extend the structure to the rear,
Grass was collected and discharged through a duct installed on one side of the aircraft.

(c) Problems to be Solved by the Invention Thus, the prior art has the following drawbacks.

In other words, when there are multiple cutting blades, it is not possible to convey and discharge all the cut grass in one direction, so the grass cut on one side of the machine is discharged forward via the conveyance duct. , the grass clippings on the other side will be discharged to the sides of the machine, and the grass clippings will be scattered around the machine and the grass collection will be complicated, and if it is discharged to the front of the machine, This has the disadvantage that it becomes a hindrance when the machine is running and makes it difficult to run smoothly.

(d) Means for solving the problem In the present invention, the lawn cut by the cutting blades is distributed to the left and right sides of the machine and transported to the rear of the machine, and the cut grass is discharged to the rear of the machine. To provide a grass discharge structure for a riding lawn mower, which enables mowing and traveling work without any hindrance, and can smoothly transport a large amount of cut grass to the rear by distributing and transporting it.

(E) Function In the present invention, the lawn mowed by the mowing operation is
It is distributed to the left and right sides of the machine body and transported and discharged to the rear of the machine body, so that the appropriate amount of grass is distributed and even a large amount of cut grass is transported appropriately.

(f) Effects According to the present invention, the mown lawn is distributed to the left and right sides of the machine body and is conveyed and discharged to the rear.
A large amount of grass clippings can be distributed and transported in an appropriate amount, and since it is distributed to the left and right sides of the machine, the entire machine can be configured to be compact, and the structure of the transportation path for the grass clippings is not strained, allowing for smooth grass cuttings. can be transported and discharged.

(g) Embodiment The embodiment of the present invention will be explained in detail based on the drawings. (△) shows a riding lawn mower, which has an operation console ( 1), a handle (2) is attached to the driver's console (1), a seat (3) is installed behind the driver's console (1), and a seat (3) is installed in front of the driver's console (1). An accelerator pedal (4) and a brake pedal (5) are provided on the left and right sides. Aircraft frame <a>
At the front, left and right front wheels (6), <6)' are installed, and at the rear, left and right rear wheels (7), (7)' are installed. Both ends of the axle (8) of the fuselage frame (a) are mounted between the frames at the rear of the fuselage frame (a) and constitute a part of the frame, and are slightly inclined toward the center of the rear of the fuselage frame (a). With the mission case (9) placed upright in between, the left and right rear wheels <7) and (7M are placed on the left and right sides of the mission case (9), and the left and right rear wheels (7), (7M) are placed close to the mission case (9).
) =, the distance between the left and right rear wheels (7) and (7M) can be made as small as possible than the left and right front wheels (6), (6)', and the distance between the left and right rear wheels (7) and (7M) can be made as small as possible within the width of the aircraft frame (a The left and right rear wheels (7), (7)' are designed to fit in the same way as a single wheel, and the left and right rear wheels (7), (7)' are designed to fit as wide as possible on both sides. A space was created so that it could be used as a discharge path for grass clippings, which will be described later.

A prime mover (E) is mounted on the aircraft frame (a) below the seat (3), and the output shaft (10) of the prime mover (El)
From there, power is transmitted to the transmission case (9) via a belt (11). (12) is the mission case (
9) is the input pulley.

In addition, below the front half of the fuselage frame (a), a pantograph-type support mechanism (1
3), and the reaping device (M) has two blades (14).

(15) are arranged on the reaping frame (m) slightly shifted from front to back and left and right, so that they can rotate outward from each other, and on the side edges of the same blades (14) and (15), Harvest blade (
16), and the shafts (17) and (18) connected to the center of each blade body (14) and (15) extend upward to form the upper end of the shafts (17) and (18). The reaping input pulleys (19) and (20) are installed in series, respectively, and the doujin coupler (
19).

In (20), power is transmitted from the output shaft (10) of the prime mover (E) via a belt (21), and in the middle of (21), the belt ( 21) is bent in the middle and suspended, and the reaping device (
This ensures smooth power transmission to M).

<22) shows the receiving pulley disposed in the middle, (23) shows the meshing gear, and <24) shows the belt for transmitting power from the right blade body (15) to the left blade body (14). There is.

(25) is a tension clutch mechanism installed in the middle of the belt (11) for power transmission to the mission case (9);
(26) is a clutch lever.

A reaping case (S) is disposed above the blade bodies (14), (15) of the reaping device (M) and around their rotation so as to cover the reaping case (S). There are left and right exhaust ducts (27) on the left and right rear surfaces of S).
, (27) ' are connected and the same duct (27), ('27
．． )=The rear end is connected to the grass collecting boxes (28), (28)- arranged on the left and right outer sides of the rear wheels <7), <7)', that is, on the rear left and right sides of the aircraft frame (a). .

That is, the left and right discharge ducts (27), (27)'', which are connected to the left and right rear surfaces of the reaping station C8), extend horizontally to the rear and are connected to the front surfaces of the grass collecting boxes (28), (28)'. The rear end openings ('29) (29)' of the ducts are configured to rise upward and communicate with the front surfaces of the upper parts of the grass collecting boxes (2B) and (28). (28>, (28)- is a rectangular frame box whose peripheral surface is formed of a mesh body, and a lower part of the outer surface is an opening/closing door (30). (31) is an auxiliary wheel of the reaping device (M).

Therefore, when mowing the lawn with the mowing device (M) or mowing the lawn with the blade body (M) while driving the rear wheels (7) and (7)', The blade bodies (14) and (15) cut the lawn with the cutting blade (16) while rotating outwardly relative to each other, and the mowed lawn is cut by the outward rotation of the blade bodies (14) and (15). It is distributed and scattered to the rear left and right sides of the case (S), carried into the left and right discharge ducts (27>, (27)'', and discharged from the reaping case (S). The grass clippings distributed and discharged to the left and right sides of the machine are stored in the grass collection boxes (28) and (2B)', especially the left and right rear wheels (7) and (7)-. The distance between them is made as small as possible to create space on both sides of the machine, so the grass collection boxes (28) and (28)' do not protrude too much from the machine, and the overall structure is compact. , the left and right rear wheels (7), (7)' have almost the same distance between the wheels as a single wheel, so in relation to the front wheels, they have the same advantages as the three-wheel Ti construction, that is, the distance required for a four-wheel structure. It does not require a differential device and can turn smoothly, and the running stability of the rear wheels is sufficient due to the four-wheel structure, even though the distance between the wheels is small. .
