Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a balance weight for a riding agricultural machine that has an engine mounted on the front of the machine and has steps on both sides.

(b) Prior Art Conventionally, as shown in Figure 8, a narrow balance weight was attached to the center of the front of the engine frame that constitutes the aircraft body, and iron plates were attached to the balance weight from the top and front side to both sides of the aircraft body. A riding agricultural machine is already known in which the iron plate is used as a bumper and a step and is connected to the left and right steps.

(c) Problems to be solved by the invention In the above-mentioned known riding agricultural machine, the iron plates for configuring the bumper and steps must be manufactured and installed separately from the balance weight, so a lot of man-hours are required to process and install them. Moreover, since the iron plate requires strength as a bumper and a step, it must be thick, and in any case, a lot of work is required and the cost is high.

(d) Means for solving the problem The present invention is equipped with an engine covered by a bonnet at the front of the fuselage, and on both sides of the lower part of the bonnet there are side sections leading from the front of the fuselage to the deck of the operating section. In a riding agricultural machine equipped with steps, balance weights are mounted on the frontmost part of the machine body, extending over both sides of the machine, at approximately the same height as the side steps, and the front parts of these side steps are placed on both sides of the balance weights. By simply casting the balance weight, it is possible to configure not only the balance weight itself but also the front step and bumper connected to the side steps, and the balance weight, step and The above-mentioned problem was solved by making it possible to assemble the bumper in one step.

(E) Effect When the balance weight is configured as described above, 1
The front step and bumper can also be manufactured in one process, and the installation process only requires installing the balance weights that perform the three functions mentioned above, and the balance weights are almost continuous with the steps on both sides of the engine, making it easy to walk. is easy.

(F) Embodiment An embodiment of the present invention and its related configuration will be explained with reference to the drawings.A transmission case 1 mounted on the front of the aircraft has a pair of left and right front wheels 2, 2 pivotably supported so as to be steerable. Although not shown, a pair of left and right rear wheels are pivotally supported at the rear of the aircraft, and the deck 5 of the rear control section, such as the handle 3 and clutch lever 4, is formed flat from one side to the other. be.

Further, an engine 7 is mounted on an engine frame 6 fixed to the front part of the transmission case 1, and flat side steps are installed on both sides of the lower part of the bonnet 8, the rear part of which is approximately the same height as the deck 5. 9,9
is provided.

When viewed from the side, the balance weight 10 has an L-shaped attachment part 11 hanging down from the lower center thereof, the upper surface is at approximately the same height as the side steps 9, and the front surface is located forward of the bonnet 8. A protruding mounting portion 11 having a vertical width substantially the same as that of the side step 9 is screwed onto the engine frame 6.

Further, the balance weight 10 has a bumper shape in plan view, and extends to a portion that substantially coincides with the outer edges of the side steps 9, 9, and the portion extending outward from the bonnet 8, that is, The parts corresponding to the front parts of the side steps 9, 9 project rearward, and these protrusions 12, 12 have low ribs on both sides of the upper surface, between which the front parts of the side steps 9, 9 are arranged. Hooks 15, 15 whose rear ends are bent upward are provided between the protruding parts 12, 12 and the central mounting part 11, respectively. These mounting portions 11, protrusions 12, 12 and hooks 15, 15 are provided protrudingly.
The hooks 15, 15 are integrally formed with the main body of the balance weight 10 by casting, and the hooks 15, 15 restrict the towing rope 25 hung on the side thereof, as shown by the chain line A in FIGS. 4 and 5b. or hang the tow rope 25 on the bent part as shown by the chain line B,
It can be hung closer to the base as shown by the chain line C.

Further, a support stay 16 is screwed onto the lower middle part of the balance weight 10, and a notch 17 provided at the upper part engages a latch 18 fixed to the lower front end of the bonnet 8. As shown in FIGS. 8a and 8b, the bonnet 8 covers only the upper part of the top and side surfaces. It overlaps the instrument panel 20, and its lower part is removably screwed onto the stay 21 with a bolt with a knob 22, so when the bonnet 8 is removed, the entire engine compartment is opened, allowing access to the engine 7 and its attached equipment. Maintenance inspection and adjustment of the belt 23 can be easily performed.

24 is a hole provided in the protrusion 12.

Balance weight 10 in the above-mentioned riding agricultural machine
When molded by casting, the front surface becomes a bumper, the upper surface becomes a front step, both sides are continuous with the side steps 9, and the hook 1 is formed into a bumper.
5 and 15 can also be formed integrally.

When the riding agricultural machine is moved to a storage place such as along a farm road in order to replenish processing materials, if the riding agricultural machine is a rice transplanter, it will drop seedlings, and if it is a seeding machine, it will drop seeds. , or, if it is a fertilizer applicator, hold the fertilizer and balance weight 10
The worker puts his foot on the front step of the machine, moves to the side step 9 behind it, and supplies the planter, seeding device, or fertilizing device via the deck 5 of the control section.

(g) Effects of the invention As mentioned above, the present invention is equipped with an engine 7 covered by a bonnet 8 at the front of the fuselage, and on both sides of the lower part of the bonnet 8, the engine 7 is connected from the front of the fuselage to the deck 5 of the driving section. In a riding agricultural machine equipped with side steps 9, 9, a balance weight 10 is placed at the forefront of the machine body and extends over both sides of the machine.
The balance weight 10 can be used as a strong front step and bumper. The supporting structure of the side steps 9, 9 can be simplified by using them as support members for the side steps 9, 9, while being able to reduce manufacturing costs by manufacturing them at the same time. and can firmly support the front portions of those side steps 9, 9.
The side steps 9, 9 will not bend even if a worker jumps off a farm road while holding heavy spare seedlings, and when installing the side steps 9, 9, the front part of the side steps 9, 9 will not bend when the front part is attached to the top of the balance weight. Its height can be determined simply by polymerizing it, and it can be easily installed at the correct height position.
