Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wheel mounting device for a mower.

(Prior art) As shown in Japanese Utility Model Application Publication No. 58-182826, mowers are generally equipped with front and rear wheels such as a cutting height adjustment gauge wheel and a limit gauge wheel located in front and rear of the mower deck. There is.

By the way, in the past, the front and rear wheels were simply attached to the mower deck via brackets.

(Problem to be solved by the invention) Therefore, in the above-mentioned conventional method, when a large impact is applied to the front and rear wheels, such as when the front and rear wheels collide with an obstacle, the impact is transmitted through the bracket. There is a problem in that the mower deck acts directly on the mower deck, causing deformation or damage to the mower deck, and in order to prevent this deformation, it is necessary to increase the thickness of the mower deck.

In addition, when the diameter of the wheels such as the gauge wheel for cutting height adjustment is increased, the height of the bracket becomes higher, but in the past, the bracket could not be attached to or detached from the mower deck, so there was a problem that it was bulky when packed. It was hot too.

An object of the present invention is to provide a wheel mounting device for a mower that can solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized in that the mower 1 provided on the traveling vehicle 2 is provided with a mower deck 16 and on the mower deck 16, and An input case 18 for receiving power from the mower deck 16, and front and rear wheels 20, 21 located at the front and rear of the mower deck 16. The frame 19 provided with front and rear wheels 20 and 21 is removably attached via buffers 33, 34, 37, and 38, and the height of the attachment part of the frame 19 on the mower deck 16 is input to the case. The point is that it is lower than 18.

(Function) According to the present invention, even if a large impact is applied to the front and rear wheels 20 and 21, such as when the front and rear wheels 20 and 21 collide with an obstacle, the impact is absorbed by the shock absorber 33,
34, 37, and 38, and a large impact will not directly act on the mower deck 16. Therefore, even if the mower deck 16 is not made thick, there is no risk that the mower deck 16 will be deformed by the impact. few.

Moreover, the frame 1 includes front and rear wheels 20 and 21.
9 can be attached to and detached from the mower deck 16, and the height of the attachment part of the frame 19 on the mower deck 16 is lower than that of the input case 18. By removing the frame 19, the height of the mower 1 can be reduced, and the packaging of the mower 1 can be made less bulky.

(Embodiment) Hereinafter, the first embodiment of the present invention will be explained based on the drawings of FIGS. 1 to 8. FIGS.
shows.

In FIGS. 2 and 3, a vehicle body 3 includes an engine 4, a transmission case 5, a pair of left and right front axle cases 6, and the like. A front PTO shaft 7 projects forward from the front surface of the mission case 5, and the mission case 5 is covered with a floor sheet 8. A recirculating device 9 is provided at the front of the floor seat 8, and a seat 10 is provided at the rear. Reference numeral 11 is a bonnet, 12 is a front wheel, and 13 is a rear wheel which is a turning wheel.

The mower 1 is attached to the front part of the vehicle body 3 via a pair of left and right connecting links 14 pivotally supported by the front axle case 6 and a hanging device 15 so as to be able to move up and down.
2 Located on the front side.

As shown in FIG. 1, the mower 1 includes a mower deck 16, a rotary cutter 17, an input case 18, a frame 19, and front and rear wheels 20, 21.
, a front limit gauge wheel 22, etc.

The mower deck 16 has openings on the lower side and the right side, and below the mower deck 16, three rotary cutters 17 are arranged side by side in the horizontal direction. Connecting links 1 are installed on both left and right sides of the front part of the mower deck 16.
A pair of brackets 23 to which 4 are detachably connected.
has been erected.

A transmission mechanism that interlocks the rotary cutter 17 is disposed above the central portion of the mower deck 16 in the front-rear direction, and is covered by a cover 24 . cover 2
An input case 18 having an input shaft 25 that interlocks with the transmission mechanism is disposed at the center in the left-right direction of 4, and the input shaft 25 is connected to the front part through a universal joint shaft 26.
It is detachably connected to the PTO shaft 7.

There are a pair of left and right frames 19, which are disposed above the left and right sides of the mower deck 16 in the front-back direction, respectively, and are detachably attached to the mower deck 16. As shown in FIGS. 4 to 7, the frame 19 includes a flat main body portion 27 that is inclined upward at the front, a front mounting plate 28 that is lowered from the front of the main body portion 27, It is composed of an inverted L-shaped rear mounting plate 29 fixed to the rear end of the main body 27 and the like.

A pair of mounting plates 30 are erected from both left and right sides of the front portion of the mower deck 16, and a front mounting plate 28 is detachably attached to the mounting plates 30 by a pair of bolts 31 and nuts 32. A plate-shaped buffer 33 is interposed between the mounting plate 30 and the front mounting plate 28, and a flanged cylindrical buffer 34 through which bolts 31 are inserted is detachably attached to the front mounting plate 28. It is installed. Note that the heights of the mounting plate 30 and the bracket 23 are lower than the height of the input case 18.

The lower end of the rear mounting plate 29 is detachably attached to the rear wall of the mower deck 16 with bolts 35 and nuts 36. A plate-shaped buffer 37 is interposed between the rear mounting plate 29 and the mower deck 16, and a flanged cylindrical buffer 38 through which bolts 35 are inserted is removably mounted on the rear mounting plate 29. There is. In addition, the buffer bodies 33, 34, 37, 38 are as follows:
For example, it is made of an elastic material such as rubber.
Further, the upper part of the rear mounting plate 29 has a horizontal step 3.
It is said to be 9.

A cylinder 40 is fixed to the front end of the main body 27,
The cylindrical body 40 is provided with a gauge wheel for adjusting cutting height, which is exemplified as the front wheel 20, and is detachably adjustable in height via a support shaft 41. In addition, front wheel 2
0 has a caster function.

A rear limit gauge wheel, exemplified as the rear wheel 21, is removably attached to the lower part of the rear mounting plate 29 via a bracket 42 with bolts 43 and nuts 44.

Incidentally, as the rear wheel 21, a gauge wheel for adjusting cutting height having a caster function as shown in FIG. It is height adjustable and detachable.

The front limit gauge wheel 22 is the mower deck 16
It is attached via a stay 47 to the center in the left-right direction of the mower deck 16, and is located in front of the mower deck 16.

FIG. 9 shows a second embodiment of the present invention, in which a mid-mount type mower 1 is mounted on a midway part of the vehicle body 3 in the longitudinal direction via a bending link mechanism 49 so as to be able to rise and fall freely. Front and rear mounting plates 50 and 51, which are lower in height than the input case 18, are respectively erected on the left and right sides of the mower deck 16, and the frame 19 is mounted on these front and rear mounting plates 50 and 51 as in the first embodiment. It is removably attached via a buffer. The frame 19 has front and rear wheels 2 which are used as gauge wheels for adjusting the cutting height and have a caster function.
0,21 are provided.

(Effects of the Invention) As described in detail above, according to the present invention, even if the mower deck is not made thick, there is little risk that the mower deck will be deformed by the impact acting on the front and rear wheels.

In addition, since the frame with the front and rear wheels is attached to the front and rear of the mower deck, the front and rear wheels have less impact on the mower deck compared to a frame in which the front and rear wheels are individually attached to the front and rear of the mower deck. The mounting strength itself can also be increased. Furthermore, even if the diameters of the front and rear wheels are made large, the mower deck can be packaged without being too bulky. The present invention has the above advantages and is of great practical benefit.
