Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a grass bag support structure for a riding lawn mower.

(Prior Art) In a riding lawn mower, a grass bag for collecting grass cut by a cutter blade is generally installed at the rear of the machine. Specifically, the rear part of the fuselage is equipped with a support frame that is approximately U-shaped in plan and open to the rear, while a bag frame that is approximately rectangular in plan is provided on the top of the glass bag, and this bag frame is placed on the support frame from the rear. . In order to maintain the placed state, conventionally, downward recesses were provided at the same positions on the opposing left and right rods of the support frame, and protrusions that engaged with these recesses were provided on the left and right rods of the bag frame. Ta.

(Problems to be Solved by the Invention) However, since the protrusion of the bag frame is simply fitted into the recess of the support frame, and the fitting depth is shallow, there is a problem in that the bag is likely to fall off during lawn mowing work.

In addition, the engaging parts are symmetrical and in the same position on both the left and right sides, so
The bag frame tends to swing around the engaging portion, which also causes the bag frame to fall off.

Therefore, an object of the present invention is to provide a riding lawn mower that improves the mounting and engagement state of the bag frame on the support frame, and also prevents the bag frame from forming a swinging fulcrum to prevent it from falling off. To provide a glass bag support structure.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides pins 21, 21 that largely protrude upward on the opposing rod portions 15, 15 of the support frame 13, which is substantially U-shaped in plan, provided on the aircraft body side. are fixed at different positions, and curved recesses 29, 29 are formed in opposing rod portions 27, 27 of the bag frame 26, which is substantially rectangular in plane, to engage with approximately half the circumference of the pins 21, 21. Features.

(Example) Examples will be described below based on the accompanying drawings.

Fig. 1 is a schematic side view of the riding lawn mower, and Fig. 2 is a plan view of the same. An engine 5 and other auxiliary equipment are mounted on the upper part, a seat 6 is mounted above it, a transmission case 7 is mounted at the rear of the frame 2, and a cutter blade 8 is mounted inside the middle part. A housed cutter housing 9 is provided. The cutter blade 8 is rotationally driven via a belt pulley mechanism 10.

The rear end of the vehicle body frame 2 is provided with two vertically long hitch pipes 11, 11 fixedly installed on the left and right, and inside these hitch pipes 11, 11 are support posts 12, as shown in FIGS. 3 and 4 from above. 12 is inserted and held. This support post 12,12
There are left and right support pipes 13 that protrude rearward,
13 are fixedly installed respectively.

The support pipe 13 has a substantially U-shaped plane that opens rearward, and the middle part of the front rod part 14 is fixed to the support post 12, and the left and right support pipes 13,
A sub-pipe 17 is installed between the rear portions of the side rod portions 15, 15 adjacent to each other and the base plate 16 between the hit pipes 11, 11.

A cover 18 is provided to cover the left and right support pipes 13, 13 to form a space, and the side wall of the cover 18 and the side wall of the cutter housing 9 are connected by a duct 19.

In the above, the vertically long pins 21 and 21 are provided at the front intermediate portion of one side rod portion 15 of the support pipe 13 and the rear intermediate portion of the other side rod portion 15, respectively.
The pins 21, 21 are fixedly fixed through the pins, and the pins 21, 21 largely protrude upward.

That is, as shown in FIG. 5, the lower half of the pin 21 is passed vertically through the predetermined portion of the side rod 15, the lower end and middle portion of the pin 21 are welded to the side rod 15, and the upper half of the pin 21 is A protruding portion 22 that largely protrudes above the side rod portion 15
shall be.

On the other hand, a bag frame 26 is provided above the glass bag 25. This bag frame 26 has a substantially rectangular plane so as to be placed on the support pipe 13, and the upper four circumferences of the cloth glass bag 25 are looped to cover the bag frame 26 and the edges are sewn. Here, when the bag frame 26 is placed on the support pipe 13, the pins 2 at the left and right side rods 27, 27 of the frame are
The parts 28, 28 to be engaged with the parts 1, 21 are cut out and exposed.

And the left and right exposed parts 2 of the bug frame 26
In the embodiment, small curved recesses 29, 29 are formed in the pins 8, 28 toward the outside to engage with approximately half the circumference of the respective pins 21, 21.

When installing the glass bag 25, hold the bag frame 26 and place it on the support pipe 13 from behind, and insert the curved recess 2 into the left and right pins 21, 21.
9 and 29 are engaged to place the bag frame 25 on the support pipe 13.

In such a placed state, the curved recesses 29, 29
Since the relatively long pin protrusions 22, 22 are exposed at the top, it is difficult for the pin to fall off when traveling during lawn mowing work. Moreover, since the curved recesses 29, 29 are engaged with approximately half the circumference of the pin protrusions 22, 22, the bag frame 26 is prevented from shifting in the left-right and front-rear directions relative to the support pipe 13. Furthermore, since the engagement parts between the left and right pins 21, 21 and the curved recesses 29, 29 are made different in the front-rear direction, the engagement parts are less likely to serve as rocking fulcrums of the bag frame 26 while the bag frame 26 is traveling. Shaking is also suppressed.

Therefore, it is possible to effectively prevent the bag frame 26 from falling off.

Incidentally, in the embodiment, the curved recess is formed toward the outside of the bag frame, but it goes without saying that the same effect can be obtained even if the curved recess is formed toward the inside.

(Effects of the invention) As described above, according to the invention, the pins protruding largely on the opposing rods of the support frame are engaged with the curved recesses provided on the opposing rods of the bag frame, and Since the engaging parts are different, the bag frame is excellently prevented from shifting and vibrations on the support frame, and the bag frame can be effectively prevented from falling off.
