ある。 In other words, in a power tiller that has a bonnet covering the upper part of the engine, including the condenser, the condenser can constantly draw in cold outside air without inhaling the air inside the bonnet, increasing cooling efficiency, and It also prevents the cooling water from decreasing, allows the condenser exhaust gas to be properly discharged to the outside without entering the bonnet, and prevents the temperature around the condenser from rising too high.It has a simple structure. The purpose of the present invention is to provide the following information so that it can be carried out suitably.
次に、図面に示す実施例について説明する。 Next, the embodiment shown in the drawings will be described.
第1図は耕耘機の側面図を示し、4はミツシヨ

ンスウエイト、8はハンドルである。 FIG. 1 shows a side view of the tiller, with reference numeral 4 a transmission case, 5 wheels, 6 a front frame, 7 a balance weight, and 8 a handle.

同様に構成する。 An engine A having a condenser a is mounted above the front frame 6, and a bonnet 1 is attached above the engine A, and a belt cover is connected to a flywheel cover 9 that covers a flywheel on the side of the engine A. 10 is arranged along the lower side of the bonnet 1 and extends above and to the side of the mission case 4, and is constructed in the same manner as the conventional structure so that power is transmitted to the mission case 4 by a belt 11 inside the belt cover 10.

The exhaust hood 3 is attached so that the tip air intake port 2a of the belt cover 2 projects outwardly through the cutout 12 on the side of the bonnet 1, and the tip exhaust port 3a of the exhaust hood 3 passes through the cutout 13 on the other side of the bonnet 1 and extends outward through the cutout 12 on the side of the bonnet 1. It is attached and configured so that the upper side projects outward.

の冷却効率が高度となる。 Therefore, during work, on the intake side of condenser a, since the intake port 2a opens outward, cold outside air can be sucked in without sucking the air inside the bonnet 1, and the engine cooling water can be sucked in. It also prevents the decrease in capacitor a.
The cooling efficiency is high.

くなる。 Further, since the exhaust gas is discharged outward from the exhaust port 3a, the temperature rise around the condenser a is reduced without entering the bonnet 1, and the temperature rise due to exhaust gas inside the belt cover 10 is also prevented.

できる特徴を有する。 In this way, the present invention is a tiller in which the engine A including the condenser a is covered with a bonnet 1. The bonnet 1 is provided on both sides of the condenser a on the intake side and the exhaust side.
The intake hoods 2 are arranged so that they do not communicate with each other.
and an exhaust hood 3 are connected to each other, and an intake hood 2
The outer edge of the tip air intake 2a of the exhaust hood 3 projects outward through a notch 12 on the side of the bonnet, and the outer edge of the tip exhaust port 3a of the exhaust hood 3 projects outward at the upper part of the belt cover 10 through a notch 13 on the other side of the bonnet, so that both ports 2a, 2b are open to the outside of the bonnet. In contrast to the conventional system in which an air duct is provided in communication with the upper part inside the bonnet, and the heated air inside the bonnet is sucked in from the duct intake side and administered to the condenser, thereby reducing the cooling efficiency, this system can always suck in cold outside air from the air intake 2a, thereby improving the cooling efficiency and preventing a decrease in engine cooling water. The exhaust gas from the condenser a can be reliably and satisfactorily discharged outward from the exhaust port 3a without entering the bonnet 1, so that the temperature around the condenser a does not rise too much. The exhaust gas can be guided and discharged so that it does not hit the belt cover, for example. This system has the characteristics of being simple in structure and being preferably implemented.
