The main body 14, the front of the gearbox 20 which will be described later in detail is integrally configured, the housing 18 has a cylinder 22 and a juice material supply hopper (a pair of pressing rollers 16, 17) is built in 24).

In the gearbox 20 formed on the front surface of the main body 14, the foremost shaft 26 of the motor 12 extends, and a small diameter helical gear 28 is integrally formed at the end.

Adjacent to this, the first shaft bar 30 is installed. The inlet end of the first shaft 30 is arranged on the bottom of the gearbox 20 and the other end of the first shaft 30 is arranged on the front cover plate 32 of the gearbox 20. The first shaft 30 has a large-diameter first helical gear 34 engaged with the small-diameter helical gear 28 on its base side, and a second helical smaller than the diameter of the first helical gear 34. The gear 36 is integrally formed, and the key 38 is integrally formed in front of the second helical gear 26.

On the other hand, the second shaft 40 is arranged adjacent to the helical gear 28 of the small diameter of the motor rotary tucks 26. This second shaft 40 is disposed at a position substantially radially opposite to the first shaft 30. One end of the second shaft 40 is arranged on the bottom of the gear box 20, and the other end extends through the front cover plate 32, and a square end 41 is formed thereon so that one side of the compression roller is formed. 16 are combined. The second shaft 40 is integrally formed with a large diameter third helical gear 42 that interlocks with the second helical gear 36 of the first shaft 30, and a key 44 is formed in front of the second shaft 40. It is.

The other pressing roller 17 is coupled to the rotary support rod 46 mounted on the front cover plate 32 independently of the structure of the reducer as mentioned above.

In the above-mentioned speed reducer structure, the rotational force is sequentially applied to the helical gear 28 of the rotating shaft 26, the first helical gear 34 of the first shaft 30, the second helical gear 36 and the second shaft 40. It is transmitted through the third helical gear 42, the rotation speed of the first shaft 30 is faster than the rotation speed of the second shaft (40).

According to the present invention, the first clutch gear 48 and the second clutch gear 50 are inserted into the first shaft rod 30 and the second shaft rod 40, respectively. The first clutch gear 48 is coupled to the key 38 of the first shaft 30 in the inner hole thereof is formed with a key 52 for connecting the first clutch gear 48 to the first shaft 30. It has a structure in which the sleeve 56 having the flange 54 extends forward.

Thus, an annular demand 58 is formed between the flange 54 and the side surfaces of the clutch gear 48.

Similarly, the second clutch gear 50 also has a flange 64 having a key engaged with the key 44 of the second shaft 40 in the same manner as the first clutch gear 40 to form the annular demand 62. The sleeve 66 having extends.

These first and second clutch gears 48 and 50 are formed on the first and second shafts 30 and 40, respectively, and the second and second helical gears 36 and 42 and the front cover plate 32, respectively. The inner surfaces of the shafts 30 and 40 are movable in the axial direction.

For example, when the first clutch gear 48 is close to the second helical gear 36 of the first shaft 30, the key 38 of the shaft 30 and the key 32 of the clutch gear 48 are closed. By being coupled, the first shaft 30 and the first clutch gear 48 are mechanically coupled so that the clutch gear 48 rotates together with the shaft 30.

If the clutch gear 48 moves toward the front cover plate 32, the key 38 of the shaft 30 and the key 52 of the clutch gear 48 are separated, and the clutch gear 48 is removed from the shaft 30. Are separated.

Similarly, when the second clutch gear 50 approaches the third helical gear 42 at the second shaft 40, the second clutch gear 50 is coupled to the second shaft 40 and is moved from the third helical gear 42 toward the front cover plate 32. As you move, it is separated.

In this way, the connecting gear 68 is coupled to the first and second cleavage gears 48 and 50 inserted and connected to the first and second shaft rods 30 and 40.

The spiral portion 72 is capable of being helically coupled to the spiral hole 73 formed in the upper portion of the cylinder 22 on the main body engaging surface side of the housing 18.

The means for mechanically connecting the above-mentioned first and second clutch gears 48 and 50 to the respective first and second shafts 30 and 40 is a clutch actuating fork 74. The clutch operating forks 74 are formed of the branches 76 and 78 inserted into the annular demands 58 and 62 of the first and second clutch gears 480 and 50, and the branches 76 and 78, respectively. The upper part is connected to the operating rod (60) extending to the upper portion of the gear box 20, the operating lever 62 is installed on the upper end of the operating rod (60).

The clutch operating fork 74 has a first clutch gear 48 engaged with, and disconnected from, the first clutch gear 30 whenever the operating lever 62 is rotated counterclockwise or clockwise. The gear 50 is separated and coupled to the second shaft 40.

In this way, when the clutch operation fork 74 is selectively operated to allow the first clutch gear 48 to be coupled to the first shaft 30, the rotational force of the first shaft 30 is transmitted through the first clutch gear 48. The flange engaging surface 19 of the housing 18 becomes the main body 14 when it is transmitted to the soft gear 68 and the spiral portion 72 at its tip is rotated so that the spiral hole 73 of the housing 18 is coupled thereto. The housing 18 is coupled to the main body 14 in close contact with the front surface, that is, the front cover plate 32. When the coupling of the housing 18 to the main body 14 is completed, the clutch operating fork 74 is placed in the neutral position. At this time, since the first and second clutch gears 48 and 50 do not have their keys 52 and 60 coupled to the keys 38 and 44 of the first and second shafts 30 and 40, Since the rotational force of the shafts 30 and 40 is not transmitted to the clutch gears 48 and 50 and the connecting gear 68 is in a stopped state, the spiral portion 72 of the connecting gear 68 is held in the housing. The state coupled to the spiral hole 73 of 18 is maintained as it is.

Afterwards, the power of the motor 12 is transmitted to the compression rollers 16 and 17 through the first and second shaft rods 30 and 40, thereby compressing the juice material by the compression roller.

On the contrary, when the housing 18 is to be separated from the main body 14, the spiral portion 73 of the connecting gear 68 is connected to the housing 18 as opposed to the coupling of the housing 18 to the main body 14. It must be reversed in helix 73.

Further, when the housing 18 is coupled to the main body 14, the spiral portion 72 has a force greater than the force that causes the spiral portion 72 of the connecting gear 68 to be coupled to the spiral hole 73 of the housing 18. ) Should be reversed. For this purpose, a second clutch gear 50 coupled to the second shaft 40 of the low speed rotation is used. That is, the clutch operating fork 74 is operated so that the second clutch gear 50 coupled to the branch 78 is mechanically coupled to the second shaft 40, so that the second shaft 40 has a rotational force. It is to be transmitted to the connecting gear 66 through the second clutch gear (50).

The connecting gear 68 is rotated in reverse and the flange 73 of the housing 18 is separated from the front surface of the main body 14 while the spiral 73 is separated from the spiral hole 73 of the housing 18. To be separated from the body 14 of the housing 18.
