Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a walking rice transplanter, and more particularly to an improvement in the arrangement structure of a muffler.

The temperature of the muffler increases with the exhaust gas, so it is necessary to avoid the adverse effects of the heat on other devices such as the engine. However, there was a risk of injury due to accidental contact with the high-temperature muffler, and the appearance of the muffler tended to reduce its commercial value.

In view of the above-mentioned points, the present invention arranges the muffler inside the bonnet without adversely affecting other devices such as the engine, thereby avoiding the risk of burns, improving the appearance, and improving the product value. Another object of the present invention is to provide a walk-behind rice transplanter that is configured to reduce the influence of exhaust gas from the 77ler on the operator and to cool the muffler well.

The characteristic configuration of the walk-behind rice transplanter according to the present invention is as follows: A control knob extends to the rear side of the machine body, and a seedling mounting table and a seedling planting device are provided in front of the handle, the upper end of which is tilted forward. In addition, in a walk-behind rice transplanter having an engine disposed in the front body, an engine cooling air supply device is disposed in front of the engine, and a transmission case is integrally connected to the engine at the rear, and the engine a muffler is disposed in a recessed space located behind the transmission case and above the transmission case, and a muffler is disposed with an exhaust port facing laterally, and a bonnet covers the upper and laterally sides of the engine and muffler; and
A large number of slits are formed in the side portion of the bonnet so that the cooling air from the supply device flows through the surfaces of the engine and the muffler to the slit side. It has an effect.

1 In other words, in walk-behind rice transplanters, the transmission system is located at a low position, so a concave space is formed between the engine and the transmission case, and in addition to this, a large concave space is created by the engine cooling air supply device. By effectively utilizing the fact that engine cooling air is sent into the space, the muffler can be placed inside the bonnet without having any adverse effects on other equipment such as the engine due to the heat of the muffler, reducing external exposure. In addition to avoiding the risk of burns associated with burns, the product also has a good appearance and can improve its commercial value.

In addition, the exhaust port of the muffler located inside the bonnet is angled toward the sides, and many slits are formed on the sides of the bonnet, so that high-temperature exhaust gas from the 77r and the inside of the bonnet can be removed. Hot air is exhausted to the sides of the aircraft.

Therefore, the seedling platform at the rear of the aircraft, which is generally wider than the bonnet in both the left and right directions and is tilted forward, prevents the exhaust gas and hot air discharged to the sides from moving to the rear. This means that high-temperature exhaust gas and hot air may come into direct contact with the seedlings on the seedling table, and direct them toward the operator holding the rear control handle. This could have been avoided as much as possible.

EMBODIMENT OF THE INVENTION Below, the Example of the walking type rice transplanter by this invention is demonstrated based on drawing.

An engine 2 is mounted on the front part of the machine body on which the wheels 1, 1 are mounted, and a seedling mounting table 3 is mounted on the rear part of the machine body, which slides back and forth in the lateral direction of the machine body in a tilted position. A seedling planting device 4 is provided to take out a seedling block for one seedling from the bottom and plant the seedlings in the rice field, and a control handle 5 is provided extending toward the rear of the fuselage, and power from the engine 2 is connected to the engine 2. The seedlings are taken out from the rear lower part of the machine body and transmitted via the transmission from the wheels 1, 1 and the transmission shaft T to the seedling mounting table 3 and the seedling planting device 4 via the planting mission 8 at the rear of the machine body.
This is a walking-type rice transplanter that plants seedlings in a rice field while moving.

Reference numeral 9 in the figure indicates a float disposed at the lower part of the machine body in order to stabilize the position of the seedling planting device 40 relative to the ground and to prepare a muddy surface for planting.

An engine cooling air supply device 10 is disposed in front of the engine 2 to suck in cooling air and supply it to the engine 2 in order to cool the engine 2.
A concave space 12 is located at the rear of the aircraft and above the mission case 11 which is integrally connected to cover the mission, and into which the cooling air from the supply device 10 flows through the surface of the engine 2. A muffler 13 is installed extending from one side of the engine 2 and facing the other side of the fuselage.
The muffler 13 is cooled after that.

The engine 2 and the muffler L13 are covered above and on both sides with a bonnet 14, and a large number of slits 16 are bored in the side surface of the bonnet 14 at a location facing the muffler exhaust port 15. The entire muffler 13 is disposed within the bonnet 14, with the exhaust gear rest forming.

In addition, the mission case 11 is located behind the engine 20 aircraft.
The transmission case 11 is not limited to a type in which a case covering the transmission shaft is integrally installed, and these cases are collectively referred to as a transmission case 11.
