Description

[Detailed description of the invention] This invention does not obstruct the operator's forward view when planting seedlings in the field, has an extremely simple mounting structure, and uses hot air discharged from the engine to support seedlings. This invention relates to an auxiliary seedling stand for a riding rice transplanter that does not have any adverse effect on the seedlings on the stand.

Conventional riding rice transplanters are also available in which auxiliary seedlings are placed on the front of the machine in consideration of the weight balance of the machine. Because the auxiliary seedlings were installed in multiple layers and protruding above the bonnet, the operator's forward view during planting was obstructed by the auxiliary seedlings, and the area in front of both the left and right sides of the aircraft was particularly difficult to see from the driver's seat. In addition to being difficult to see, the auxiliary seedling stand is mounted close to the engine due to the structure of the aircraft, so the hot air from the engine directly hits the seedlings on the auxiliary seedling stand, which causes the seedlings to have insufficient resistance. There was a risk that the plants would wither after planting.

The present invention was developed to eliminate the above-mentioned drawbacks, and by improving the mounting position of the auxiliary seedling stand without disturbing the balance of the machine, it is possible to maintain a good forward view of the operator. Rather, the object is to provide an auxiliary seedling stand for a riding rice transplanter that has an extremely simple mounting structure and that can reliably prevent the inconvenience of hot air discharged from the engine hitting the seedlings on the auxiliary seedling stand. be.

To explain the configuration of the present invention with reference to an embodiment shown in the drawings, A has a pair of left and right front wheels 1, 1 and rear wheels 2, 2 that are pivotally supported, an engine 3 in the front, and a driver's seat 4 in the rear. A planting section B consisting of a float 5, a planting rod 6, a seedling stand 7, etc. is connected to the rear of the traveling machine A so that it can move up and down and roll. These components constitute a riding-type rice transplanter. Numeral 8 is a steering handle provided in front of the driver's seat 4, and numeral 9 is a driving operation panel. Various operating levers, pedals, etc. are arranged around the driver's seat 4, and all can be operated by hand. It is becoming possible to do so. 10 is step, 1

Further, a bonnet 16 is mounted above the engine 3 and the fuel tank 11 so as to be openable and closable. The upper surface of the bonnet 16 is slanted over its entire length in the front-rear direction, so that the front visibility is improved and the design value of the bonnet itself is improved.

Further, a notch 16a that is long in the longitudinal direction from the front side of the engine 3 to the rear side of the bonnet 16 is provided on the side surface of the bonnet 16, and the hot air heated by the engine 3 is cooled by a cooling fan (not shown). The hot air is guided into a duct 17 provided at the rear of the side, and is forcibly discharged from a hot air outlet 17a located at the rear upper part of the notch 16a in the direction of arrow A in FIG.

Reference numeral 18 denotes a fender for the front wheels 1, 1, the rear side of which is inclined downward so as to be connected to the step 10, and a headlight 19 is attached to the front end of the fender. 20 is an auxiliary seedling stand, and the auxiliary seedling stand 2
0 is located on the front side of the hot air outlet 17a and is located on one side of the upper surface of the fender 18, and the fender 18
A bracket 21 and a bolt 22 are attached to the outer surface of the bonnet, and the mounting position thereof is structurally lower than the top surface of the bonnet 16 as shown in FIGS. It constitutes an auxiliary seedling stand 20 to support. And this auxiliary seedling stand 2
0 is a planar square-shaped bar 20a having a rising portion 20'a on the outside, and a bar 20b having rising portions 20'b at both front and rear ends, which are integrally framed by welding or the like, and are attached to both sides of the bonnet 16. The left and right auxiliary seedling stands 20, 20 attached to the seedling stand are respectively constructed of the same parts and the same shape. Reference numeral 23 denotes an L-shaped stopper, which is fixed to one side of the upper surface of the fender 18 via a bracket 24 and a bolt 25, and the planted seedlings P can be placed in the auxiliary seedling stand while still in the seedling box. 20.

In the figure, reference numeral 26 denotes auxiliary seedling stands disposed on both the left and right sides of the driver's seat 4, and in the illustrated example, the auxiliary seedling stands 26 have a structure in which two stages are stacked on each side,
The structure is such that the planted seedlings can be placed on the front, rear, left and right sides of the aircraft A in a well-balanced manner.

In the configuration as described above, in advance during planting work,
Pine seedlings are placed on the seedling stand 7 of the planting section B, and are stored in seedling boxes on the auxiliary seedling stands 20, 20 on both sides of the bonnet 16 and the auxiliary seedling stands 26, 26 on both sides of the driver's seat 4, respectively. Work is started by placing the planted seedlings P as they are. In the present invention, the front auxiliary seedling stands 20, 20 are placed below the top surface of the bonnet 16 and at a distance from the front wheel fenders 18, 18. Since the bonnet 16 is placed on the outer side of the opened auxiliary seedling stands 20, 20, the operator's forward view is not obstructed by the planted seedlings P placed on the auxiliary seedling stands 20, 20, and the bonnet 16 is placed at a low front. Coupled with the high rear slope, the operator's forward visibility during operational work is good not only in front of the center of the aircraft A, but also in front of both sides of the bonnet 16, making it easy to perform line alignment using markers, etc. I can do it. In particular, since the bonnet shape is downward-sloping over its entire length, the field conditions located directly in front of the machine A can be seen directly from the driver's seat 4, resulting in even better operability.

Furthermore, during work, the inside of the bonnet 16 tends to reach a high temperature due to the heat generated by the engine 3, but the hot air heated by the engine 3 is blown to the rear of the engine 3 by a cooling fan (not shown) and guided by the duct 17. The hot air is then forcibly discharged from the hot air outlet 17a toward the rear of one side of the engine 3, as shown by arrow A in FIG. Therefore, the front auxiliary seedling stand 20, 20 in the present invention is connected to the hot air outlet 1 of the engine 3.
7a, and are arranged on both sides of the bonnet 16, and the rear side of the front wheel fender 8 is sloped downward so as to be connected to the step 10, so that the hot air from the engine 3 flows through the fender. It is guided by the rear part of the seedling tray 18 and discharged smoothly, and does not directly hit the planted seedlings P on the auxiliary seedling stand 20, 20, so that the planted seedlings, which are still weak in resistance before being transplanted, are not exposed to hot air. It is possible to reliably prevent damage to the leaves and stems and damping off after planting.

On the other hand, since the auxiliary seedling stands 20, 20 have a mounting structure that is directly attached to the side surface of the fender 18 of the front wheels 1, 1, there is no need to separately take out the mounting frame of the auxiliary seedling stands 20, 20 from the engine frame 12, etc. Moreover, since the left and right auxiliary seedling stands 20, 20 have the same shape, the structure is simple and the cost is reduced.

Furthermore, since the auxiliary seedling stands 20, 20 are installed at a low position, stable running performance can be maintained without unnecessarily raising the center of gravity of the machine body A, and seedling replenishment work and auxiliary seedling work can be done easily. There is an advantage that the work of placing seedlings on the stands 20, 20 is facilitated.

In short, the present invention is a riding rice transplanter in which an engine is mounted at the front of a traveling machine body and a bonnet covers the engine, and the front wheel fenders are tilted downward on both sides of the bonnet so that the rear side is connected to the step. The seedling box is supported by both one side of the top surface of the fender and a bar extending laterally from the outer surface of the fender, which is located below the top surface of the bonnet and forward of the hot air outlet of the engine. Since the auxiliary seedling stand is equipped with auxiliary seedling stands on both sides in front of the driver's seat, it is possible to eliminate the inconvenience of the operator's field of view being narrowed due to the planting of seedlings on the auxiliary seedling stand. can maintain good forward visibility at all times.

In addition, since the bars and stoppers that make up the auxiliary seedling stand are simply attached to the fenders on the front side, the installation structure is extremely simple, and the auxiliary seedling stand is installed at a low position, which improves the balance of the aircraft. It is possible to maintain stable running performance without any loss of stability.

Furthermore, loading and unloading of planted seedlings to and from the auxiliary seedling stand is easy, and the hot air from the engine is guided to the sloped part at the rear of the fender and is smoothly discharged diagonally downward to the rear. It has practical effects such as being able to reliably prevent any adverse effects on the seedlings planted on the seedling stand from directly or previously being planted.
