Description

[Detailed explanation of the idea] The present invention relates to a transmission device in a rice huller.

In other words, the power can be selectively transmitted by the motor built into the huller or by the engine installed outside, and in places where the motor cannot be used, it can be driven by the engine, making it convenient to use. Regardless of whether the drive is driven by one or the other, it can be easily set by replacing the belt, and in either case, transmission can be performed reliably and well, and the structure is simple and can be suitably implemented. .

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the entire rice huller. Above the base 12 which can be placed on the ground, there is a long wind sorting box 14 equipped with a suction dust extractor 13, each conveyor, a sorting air passage, etc. Above one end of the wind selection box 14, a supply tank 15 and a head 16 equipped with both roll removal 1 are arranged in series, and above the other end of the wind selection box 14 are rotary sorting cylinders 17, 17 and a conveyor 18. , 18, etc. are installed in series, and the structure is similar to the conventional structure.

An upper pulley 2 is fitted and fixed on the drive shaft 20 of the roll removal 1 which is protruded from the side of the head 16, and a pulley 9 is detachably fitted on the outside. Wind selection box 14 in the lower part
The shaft 2 of the conveyor in the wind selection box 14 is on the side of the
1 is provided protrudingly, and a small diameter transmission pulley 22 and a large diameter intermediate pulley 3 are provided inside and outside the end of the shaft 21.
A pulley 23 is fitted and fixed, and is mounted on the side of the wind selection box 14, a pulley 24 on the conveyor shaft, a pulley 25 on the suction dust remover 13, and an intermediate guide pulley 2.
6, 27 and the transmission pulley 22, a belt 28 is wound around the transmission pulley 22, and a pulley 30 which is transmitted to a transmission case 29 installed below one end of the rotary sorting device 19 has a pulley 31 coaxial with the pulley 23. A belt 32 is passed around the belt 32 to transmit power to each part of the fuselage.

The lower end base of the elastic arm 4 extending upward is attached to the end of the shaft 21 on which the intermediate pulley 3 is fitted.
A tension pulley 5 located between the upper pulley 2 above and the intermediate pulley 3 below is mounted on the tip of the compression arm 4, and the wind selection box 14 A tension spring 34 is connected between the support pin 33 protruding from the side and the compression arm 4, and the pulley 6 of the motor M installed inside one end of the wind selection box 14 is exposed to the side. .

Further, the guide pulley 35 is mounted coaxially with the guide pulley 26, and the engine E can be installed near one end of the wind selection box 14, and the pulley 10 is mounted on the side of the engine E. Configure.

In addition, in the figure, 7, 8, and 11 are belts.

Therefore, when driven by an internal motor M, as shown in FIGS. 1 and 2, when the belt 7 is wrapped around the pulley 6, intermediate pulley 3, upper pulley 2, and tension pulley 5, The tension pulley 5 pulled by the tension spring 34 can press against the belt 7 and tension the belt 7 so that it has an L-shaped side, and the motor M can directly drive the derolling 1 via the belt 7. , can be transmitted from the intermediate pulley 3 to other parts.

In addition, when driving by the engine E without using the motor M, as shown in FIG. 3, the engine E is installed near the huller, and the belt 7
Then, another belt 8 is placed around the upper pulley 2, the intermediate pulley 3, and the tension pulley 5, and the belt 11 is placed around the pulley 9 fitted coaxially with the upper pulley 2, the pulley 10 of the engine E, and the guide. When hooked around the pulley 35, the engine E can directly drive the derolling 1 via the belt 11, and can also transmit power from the intermediate pulley 3 to other parts via the belt 8.

Regardless of whether the power is transmitted by motor M or engine E, the belt must be replaced.
Both belts 7 and 8 can be tensioned by a tension pulley 5.

In this way, the present invention has a tensioner at the tip of the pressure arm 4, which is coaxially supported with the intermediate pulley 3, between the upper pulley 2 for driving the roll removal 1 and the lower intermediate pulley 3 that drives each part of the machine body with a belt. When a tension pulley 5 is installed and a motor M is installed inside the aircraft body, one belt 7 is routed from the pulley 6 of the motor M to the upper pulley 2, intermediate pulley 3, and tension pulley 5, and When the engine E is installed outside the fuselage, one belt 8 is passed around the upper pulley 2, intermediate pulley 3, and tension pulley 5, and a pulley 9 of the engine E is connected from the pulley 9 coaxial with the upper pulley 2. Since the belt 11 is installed around the
Alternatively, the power can be selectively transmitted by an engine E installed outside, and can be conveniently used in places where the motor M cannot be used. can be easily set by replacing the belt, and in any case, the tension pulley 5 can be used to set the belt 7 or belt 8.
In any case, the motor M or the engine E can directly drive the de-roll 1 through the belt, and the transmission can be performed reliably and strongly. It has the advantage that it can be implemented easily with a simple structure.
