Description

[Detailed Description of the Invention] (b) Industrial field of application The present invention relates to a balance weight mounting device for a mobile agricultural machine such as a rice transplanter, and more specifically, a balance weight mounting configured to mount a balance weight on a bumper. Regarding the device.

(B) Conventional technology Generally, in mobile agricultural machines, the balance before and after the traveling machine body changes depending on the weight of the working machine mounted on the rear part of the machine body.
A balance weight is attached to the front part of the machine body, for example, in the vicinity of the front bumper in order to appropriately adjust and maintain the balance.

Then, as disclosed in Japanese Utility Model Publication No. 58-2705, a plurality of balance weights are provided inside the hitch box which is a bumper installed in the front part of the body of a mobile agricultural machine, and in the rear part and the front part of the hitch box. A front weight attachment device has been devised that is configured to be appropriately fixed with a plurality of bolts.

(C) Problems to be Solved by the Invention However, although the front weight attaching device described above can adjust the body balance appropriately by mounting a large number of balance weights, the front portion of the hitch box,
Since the balance weight must be fixed to the inside and the rear by using a plurality of bolts, the attaching and detaching work is very troublesome. Furthermore, since the balance weights attached to the hitch box are all exposed,
It looks inferior in appearance.

Therefore, an object of the present invention is to provide a balance weight mounting device for a mobile agricultural machine which is configured so that the balance weight can be housed inside the front bumper and thus solves the above-mentioned problems.

(D) Means for Solving the Problems The present invention has been made in view of the above circumstances, and for example, referring to FIGS. 1 and 2, the traveling vehicle body (3)
In a mobile agricultural machine (1) having a bumper (15) in the front and a working machine (14) mounted in the rear, a space (inward of the bumper (15) facing the rear of the traveling machine body ( 15a) is formed, and a bolt hole (25) into which a bolt (23) can be inserted is formed on the front wall of the void (15a) in the longitudinal direction of the fuselage to balance the void (15a). The weight (26) is housed and arranged, and the bolt (23) inserted from the bolt hole (25) is configured to penetrate through the through hole (24) formed in the balance weight (26) to be fastened and fixed. Is characterized by.

(E) Operation Based on the above configuration, when the balance weight (26) is mounted on the mobile agricultural machine (1) to perform the balance adjustment, the bumper (1
The required number of balance weights (26) are stored in the void (15a) of 5), and in this state, the bolts (23) inserted through the bolt holes (25) formed in the front wall of the bumper are replaced with the balance weights (26). ) Through the through hole (24) formed in
Fasten and fix. Therefore, the balance weight (26) is mounted in a state of being housed inside the bumper (15).

The reference numerals in parentheses are for reference to the drawings, but do not limit the configuration in any way, and even the same reference numerals are described based on the scope of claims for utility model registration. It may be different from the name of the embodiment shown below.

(F) Example Hereinafter, an example according to the present invention will be described with reference to the drawings.

As shown in FIGS. 2 and 3, the rice transplanter 1 has a traveling machine body 3 swingably supported by wheels 2, the machine body 3 including an engine 5, a mission, and the like.
A planting rod 7 is provided on the rear side of the plant rod 7 so that the plant rod 7 can be rotated by power transmission from the mission. Further, the traveling machine body 3 has a float 9 swingably suspended therebelow, and a handle 10 extends rearward. Then, along the handle 10, a seedling stand 11 that constitutes the planting section 14 is slidably supported by a slide piece.
Reference numeral 11 is configured to be reciprocally driven left and right by a lateral feed drive device 12. Further, a bumper 15 is installed at the tip of an engine frame 13 extending forward from the traveling machine body 3, a bonnet 16 is installed above the engine 5, and an auxiliary seedling stand 16 is provided behind it. Is installed.

On the other hand, the engine frame 13 is shown in FIG.
As shown in (b), it is composed of left and right frames 13a, 13b extending in the front-rear direction of the traveling machine body 3, and the frames 13a, 13b.
The bumper 15 is fixed to one end facing forward. Further, engine mounting plates 17 and 19 are installed between the left frame 13a and the right frame 13b.

The bumper 15 has a void portion 15a formed inward thereof toward the rear of the fuselage, and a recess 20 formed in the front portion thereof toward the rear of the fuselage. Further, the recess 20
The holes 21 and 21 are formed in the hole 21 and the bolts 22 and 22 inserted into the holes 21 and 21 cause the bumper 15 to move the left and right frames 13a and 1a.
It is fastened and fixed to the tip of 3b. Further, a bolt hole 25 into which the balance weight mounting bolt 23 is inserted is formed in the front portion of the bumper 15 between the holes 21 and 21, and each of the plurality of balance weights 26 accommodated in the void portion 15a is ... The formed through hole 24 is penetrated by a mounting bolt 23 inserted from a bolt hole 25, and is fastened with a nut 27 from the rear side of the machine body, so that the balance weight 26 is fixed to the traveling machine body 3. There is.

Since the present embodiment is configured as described above, the wheels 2 are driven by the rotation of the engine 5 being transmitted, and the rice transplanter 1 floating on the rice field at the float 9 runs and further planted. By driving the rod 7, a large number of mat seedlings placed on the seedling stand 11 are scraped out little by little and planted on the rice field.

Then, when adjusting the weight balance of the traveling machine body 3 that has changed due to the attachment of the fertilizer tank, etc., the required number of balance weights 26 are stored in the space 15a of the bumper 15 between the left and right frames 13a, 13b. In this state, the balance weight mounting bolt 23 inserted from the bolt hole 25 penetrates the through hole 24 of the balance weight 26, and the nut 27
The balance weight 26 is attached to the traveling machine body 3 by tightening. Further, at the time of balance adjustment, if some of the balance weights 26 are already supported by the mounting bolts 23, the nut 27 is removed and the other balance weights 26 are passed through the bolts 23, and Tighten and fix with nuts 27 when the number of sheets has passed. Therefore, the work of attaching the balance weights 26 can be easily performed by operating the single bolt 23.

As shown in FIGS. 4 (a) and 4 (b), these plates 17, 1 between the engine mounting plates 17 and 19 are arranged.
A reinforcing guide plate 30 is installed slightly below 9 so as to extend over the left frame 13a and the right frame 13b.
A balance weight 31 is provided in a space surrounded by the upper surface of 30 and the lower surfaces of the engine mounting plates 17 and 19 and the left and right frames 13a and 13b.
Is inserted and arranged, and the bolt holes of the balance weight 31 and the bolt holes of the engine mounting plates 17 and 19 are aligned, and the engine 5 is mounted from above the plates 17 and 19, and the bolt 32 When the balance weight 31 is attached to the lower portion of the engine 5, the engine 5 is configured to be fixed together with the weight 31 and the weight 31 is placed on the reinforcing guide plate 30 in advance. 17 and 19 can be easily tightened together so that it is not necessary to work while supporting the weight 31 from below, and the workability during assembly or maintenance can be improved. good.

(G) Effect of the Invention As described above, according to the present invention, the bumper (15)
Balance weight (26) in the void (15a) formed in
The balance weight (26) can be easily attached / detached, and the weight balance of the traveling machine body (3) can be adjusted well at any time, because it is configured to be stored and fastened / fixed with the bolts (23). The balance weight (26) attached can be stored and arranged inside the bumper (15) so that the appearance is not inferior.
