Abstract

PURPOSE:To use a brake drum both for the reinforcing member of an axle case and the brake drum by a method wherein the brake drum is formed integrally with the axle case, attached to the left and right sides of a transmission case, at the abutting part thereof. CONSTITUTION:In the braking device, the axle 20, rotated by an output shaft 17 through bevel gears 18, 19, is supported in the transmission case 14 provided at the rear part of body of the rice-plantation machine and the axle case 15 is connected to both left and right sides of the transmission case 14 through retaining screws 21. The brake drum 24 is formed integrally with the axle case 15 at a part whereagainst the transmission case 14 abuts. A brake shoe 22 is fitted slidably to the outer periphery of the axle 20 at the connecting part between both cases 14, 15 and is energized toward the side of the transmission case 14 through a spring 23. According to this constitution, the brake shoe 22 is moved through a fork lever or the like against the spring 23 to abut it against the brade drum 24 and, thus, braking force may be obtained.

軸を小径にする目的を果す。In Fig. 2, 14 is a transmission case provided at the rear of the vehicle body 1, 15 is an axle case attached to the transmission case 14, and 16 is a wheel transmission case. Install the shaft 17,
A bevel gear 18 is attached to the tip of the output shaft 17, a bevel gear 19 is meshed with the bevel gear 18, and an axle 20 of the bevel gear 19 is inserted into the axle case 15. The axle case 15 has a set screw 21
After coming into contact with the side surface of the transmission case 14, it is fixed. Therefore, the axle 20 is formed to protrude longer than the transmission case 14 into the axle case 15, and the outer periphery of the axle 20 extends between the mission case 14 and the axle case 1.
A brake shoe 22 is fitted into the joint portion 5 so as to be slidable from the transmission case 14 side toward the axle case 15. 23 is a spring wound around the outer circumference of the axle 20;
The spring 23 causes the brake shoe 22 to move toward the transmission case 14 from the axle case 15 at all times. A portion of the axle case 15 that comes into contact with the transmission case 14 is provided with a brake drum 24 formed as one piece. The brake drum 24 is formed together with the axle case 15 when the axle case 15 is formed. The brake drum 24 is in contact with the outer wall surface of the mission case 14 and forms a part of the mission case 14. Since the axle case 15 has the purpose of surrounding the axle 20 and attaching the rear wheel 3 via the wheel transmission case 16, the axle case 15 is formed to have a diameter that meets the purpose, but the axle case 15 does not need to be made so large in diameter.
Since the purpose of surrounding 0 can be achieved, it is desirable to form the diameter as small as possible. On the other hand, since the brake drum 24 acts as a brake when the brake shoes 22 come into contact with its inner surface, it is formed to have a considerably large diameter, and therefore also serves as a strength member of the axle case 15, and is intended to reduce the diameter of the axle. fulfill.

次に作用を述べる。Next, we will discuss the effect.

Scrape the plants one by one with a planting rod 11 and plant them on the rice field. When the brake pedal is pressed to stop the vehicle, the brake shoes 22 move outward against the elasticity of the spring 23 and come into close contact with the inner surface of the brake drum 24. Therefore, the axle 20
is stopped and the purpose of the stop is achieved.

Therefore, in the known brake drums, the brake drums are only effective as brake drums, and no further effects can be expected.

できる。However, in the present invention, an axle case 15 protruding in the left and right direction is attached to the left and right sides of a mission case 14 of a rice transplanter, and a wheel transmission case 16 is attached to both left and right ends of the axle case 15. Inside the case 15, the axle case 1 is inserted from the transmission case 14.
5, an axle 20 is provided on the outer periphery of the axle 20, and a brake shoe 22 is provided inside the mission case 14, which moves in the direction of the axle case 15 when braking is performed. Since the braking device for the rice transplanter has a large diameter and integrally forms the brake drum 24 that the brake shoes 22 contact, the brake drum 24 becomes a strong member of the axle case 15, and the end portion of the axle case 15 has a small volume. Since it can be produced simply by expanding the scale, it can be expected to be extremely inexpensive.
