Description

[Detailed explanation of the idea] It is becoming common practice to avoid fields with poor footing and to get on and off the riding rice transplanter from the ridges as much as possible. When workers put their feet on the steps, mud often became smeared on the top surface of the steps, making them slippery and dangerous when workers got on and off the steps. This occurs due to the action of water in the mud, and measures have been taken to prevent slipping, such as installing rubber plates with uneven surfaces on the steps, but The reality was that if it became clogged with mud, it would not be very effective.

The present invention was developed in view of the above circumstances, and its purpose is to prevent the danger of workers slipping on the steps by drying the mud adhering to the top surface of the steps. .

The characteristic configuration of the present invention for achieving the above object is to provide a step for getting on and off from the front side of the aircraft body at a side position of the engine bonnet on the front side of the boarding operation section, and a step for getting on and off from the front side of the aircraft body. In the above-mentioned riding rice transplanter, a fan is provided inside the bonnet and in the vicinity of the engine, the fan being driven by the engine and generating fluid cooling air for sucking in outside air and cooling the engine. An air guide cover is provided above the engine to guide the fluid cooling air, which is tinged with hot air after cooling the engine, toward the boarding/exiting step. A blow-through hole with a rectifying piece is formed for blowing and guiding the hot air guided by the wind cover onto the boarding/exiting section step.The functions and effects of this structure are as follows.

When the engine is driven, the fan rotates and the generated flowing air cools the engine, and the cooled hot air is guided toward the side where the boarding/exiting steps are installed by the air guide cover, which also has a rectifying piece. The blowout is guided to the upper surface of the boarding/exiting step through the blowhole. Therefore, as long as the engine continues to be driven during work, the steps will continue to dry.
For example, if there is mud on the steps when getting on the aircraft, as the work continues for a while, the mud on the top of the steps will dry and there will be less chance of slipping when getting off the aircraft. In addition, even on days when there is light rain, the top surface of the steps is kept dry, reducing the chance of slipping, thereby preventing danger to workers and allowing them to work safely.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, an engine 4 is mounted on the front part of a vehicle body frame 3, which is equipped with a pair of left and right front wheels 1 for steering and a pair of left and right rear wheels 2 for propulsion, and a boarding and driving section 5 is provided in the center part. At the same time, there is a forward-inclined seedling tray 6 on which pine-shaped seedlings W are placed and it moves back and forth horizontally with a constant stroke, and seedlings are taken out one by one from the bottom end of the seedling tray 6 and planted on the mud surface. A seedling planting device 9 equipped with six seedling planting arms 7 attached to the vehicle body, a plurality of floats 8 juxtaposed in the left-right direction of the vehicle body, etc. is attached to a link mechanism 10 at the rear of the vehicle body frame 3.
The rice transplanter is connected to the vehicle body via a hydraulic cylinder 11 so that it can be raised and lowered freely, thereby constructing a six-row riding rice transplanter.

As shown in FIGS. 1 to 3, a flat plate-shaped step 13 is attached to the front end of the vehicle body frame 3 toward the front of the engine bonnet 12 that covers the engine 4, etc. It is a large casting, and by connecting the seedling planting device 9, it improves the rearward shift of the center of gravity and assists the worker in getting on and off. or,
A step 14 for getting on and off the vehicle is provided on the left side of the engine bonnet 12, and a plurality of tiers of standby seedling stands 15 are provided further outward from the step 14, and a stand 15 for placing seedlings is provided on the symmetrical position of the aircraft. A plurality of tiers of spare seedling stands 15 are also arranged on the right side of the table. Further, numeral 16 in the figure is a preliminary seedling scooping board placement section.

The engine 4 is mounted on the vehicle body frame 3 so that the crankshaft faces in the left-right direction of the aircraft, and a rotor 19 is provided with a ring gear 17 that meshes with the output gear of the starter motor and a fan 18 at the right protruding end of the crankshaft. A rotor cover 20 is disposed outside the rotor 19. An output pulley 21 is drivingly connected to the left end of the crankshaft, and a belt 22
is wound. Further, heating fins 4a are formed on the upper part of the engine 4, and an air guide cover 23 is attached to the upper part of the engine 4 so that the air blown from the fan 18 can be effectively guided. Further, on the left side surface of the engine bonnet 12, there is a blow-through in which a plurality of rectifying pieces 24 are provided diagonally downward so that the air from the fan 18 can blow through the boarding/exiting step 14 provided outside the bonnet 12. A hole 14a is provided so that the top surface of the step 14 for getting on and off the vehicle is constantly dried by the hot air from the engine 4. Alternatively, the hot exhaust air may be flowed over the step 13 at the front end or over the driving section step to dry and solidify the mud on the top surface of the step.

As shown in FIG. 4, a link mechanism 10 for raising and lowering the seedling planting device 9 has an upper top link 10a.
and a pair of lower left and right lower links 10b, 1
0b, the hydraulic cylinder 11 has a ring plate 25 attached to the rod 11a,
Further, a spring cover 26 is provided, which has a large opening in the front so that the rod 11a can be moved in the direction of expansion and contraction, and a small opening in the rear so that the rod 11a can be inserted therethrough.
5 and the rear end surface of the spring cover 26, a suspension spring 27 is installed concentrically with the rod 11a. Pins 28, 28 are fixed to both sides of the spring cover 26, and are connected to a swing arm 29 extending from the top ring 10a, and the bottom end of the hydraulic cylinder 11 is connected to the vehicle body frame 3. The pin 3 is inserted into the through hole 80a drilled in the bracket 30 attached to the
1. In addition, a through hole 80b is further bored in the bracket 30 slightly behind the through hole 80a in a direction substantially along the direction of expansion and contraction of the cylinder 11, so that when a fertilizing device or the like is attached to the seedling planting device 9. By compressing the suspension spring 27, the hydraulic cylinder 1
The amount of deviation in the drive range of the cylinder 11 can be reduced by replacing the connecting pin 31 at the bottom end of the cylinder 11 with the through hole 30b.
