Inside the treatment box 18, the first and second stirring shafts 36 and 38 are rotatably installed in parallel with each other. The first and second stirring shafts 36 and 38 are installed in the direction from the front to the rear of the treatment box 18. Several actuating arms 40 protrude from the first and second stirring shafts 36 and 38 along their respective longitudinal directions. In order to enhance the effect of stirring, the specific shape of the operating arm 40 can be modified as much as possible with reference to the known art. Since the 1st and 2nd stirring shafts 36 and 38 have the same structure, the following description is demonstrated on behalf of the 1st stirring shaft 36. FIG.

7 is for explaining the installation method of the stirring shaft. Referring to FIG. 7, several working arms 40 are installed along the longitudinal direction of the first stirring shaft 36. As shown, the operating arm 40 is installed in three places along the longitudinal direction. The 1st stirring shaft 36 is a pipe, and is easy to install and remove. A hub 42 is rotatably coupled to the rear sidewall of the treatment box 18 by a journal bearing 44 (see FIG. 6, for example, a DU bushing), and at one side of the hub 42 is a hub shaft. 46 is integrally formed to protrude about 20 to 80 mm into the treatment chamber 18.

At the end of the hub shaft 46, the engaging projection 48 protrudes in the radial direction. A coupling groove 50 cut in a "b" shape as the width of the coupling protrusion 48 or more is provided at one end of the first stirring shaft 36 made of a pipe. By coupling the coupling groove 50 and the coupling protrusion 48, the first stirring shaft 36 may be coupled to the hub 42. In addition, the other end of the first stirring shaft 36 is slidably fitted to the fixed shaft 52 which is fixed to the front side wall of the processing box 18 through the journal bearing 44 '. This allows the user to simply separate or assemble the first stirring shaft 36 and the treatment box 18.

According to an embodiment of the present invention, the operating arm 40 may be in the form of a pipe with a rod or a tip, and the operating arm coupling hole 54 penetrated at right angles along the longitudinal direction of the first stirring shaft 36. Is fitted and fixed. The fixing method of the operation arm 40 and the first stirring shaft 36 can be variously selected, such as welding. The operating arm 40 is preferably installed at different angles from the axis center of the first stirring shaft 36, respectively. For example, when three operating arms 40 are installed as shown, each separation angle is preferably set to about 120 ° in consideration of balance. In addition, the operating arms 40 of the first and second stirring shafts 36 and 38 are slightly offset from each other so that interference does not occur during rotation.

Hereinafter, the driving method and the power transmission method of the first and second stirring shafts will be mainly described with reference to FIGS. 5 to 6 and with reference to FIGS. 4 and 7.

In the power transmission means according to the embodiment of the present invention, teeth 56 and 57 are protrudingly formed on the connection surfaces 62a and 64a facing each other, and thus move forward and backward in the normal direction with respect to the connection surfaces 62a and 64a. Engaging to be installed in the processing 18 so that one can be connected to the drive motor 60 via the gear train 58 and the other to the first stirring shaft 36 so as to transfer torque by selectively connecting by means of And first and second clutch plates 62 and 64 in the form of dog clutches.

 In addition, the first and second driven gear wheels 66 and 68 connected to the first and second stirring shafts 36 and 38, respectively, are directly engaged. This can be achieved by increasing the diameter of the first and second driven gear wheels 66, 68, but in some embodiments it is also possible to install an idle gear in the middle. The slide 18 is also slidably like a drawer by pushing and pulling the front door 12 in a state where the treatment box 18 is seated at a specific position on the trolley 14 integral with the front door 12 of the outer housing. By being able to pull in or pull out, the first and second clutch plates 62 and 64 can be selectively connected. The first and second clutch plates 62 and 64 may be made of metal or synthetic resin. If you want to prevent metallic noise at the moment of connection, it is recommended to use synthetic resin.

Hereinafter, an operation process including a power transmission process will be described in more detail with reference to the same drawings. The first and second stirring shafts 36 and 38 are rotated in opposite directions to each other, preferably in a direction in which the food is placed on the bottom of the processing box 18 in a upward direction to lift the food. The first and second stirring shafts 36 and 38 are connected to each other by first and second driven gear wheels 66 and 68 of large diameters which are engaged with each other to rotate simultaneously. The driving force of the drive motor 60 in which the geared motor is used is transmitted to the hub 42 which is connected to the first stirring shaft 36 and the shaft. The first driven gear wheel 66 is integrally connected to the hub 42, whereby the driving force is transmitted to the first driven gear wheel 66.

According to the present invention, the rotation speed of the first stirring shaft 36 is set to 5 to 6 rpm or less. In some cases, the timer may be intermittently rotated by a timer rather than a continuous rotation.

The treatment box 18 and the drive motor 60 must be connected to selectively transmit torque. This is because the treatment bin 18 must be removable. The first and second driven gear wheels 66 and 68 are fixed to the outer wall of the treatment box 18 to be integrated with the treatment box 18. By using the first and second driven gear wheels 66 and 68 as a synthetic resin, the weight burden thereof will be reduced.

Hereinafter, the clutch means for the selective shaft joint of the drive motor 60 and the processing box 18 will be described. The drive motor 60 transmits torque to the first clutch plate 62 through the gear train 58 (bevel gear, etc.). A second clutch plate 64 of the same type, which is installed to face the first clutch plate 62, is connected to the hub 42. Teeth 56 and 57 protrude from the connecting surfaces 62a and 64a of each clutch plate. The first and second clutch plates 62 and 64 are so close as to be in contact with each other when the treatment box 18 is fully seated in the trolley 14 and the front door 12 is completely closed. In this state, the teeth 56 and 57 cross each other to cause interference with each other. In this state, when the first clutch plate 62 is rotated by the driving motor 60, the side of the teeth 56 of the first clutch plate 62 exerts a force on the side of the teeth 57 of the second clutch plate 64. Will be added.

The teeth 56 and 57 protrude from the connecting surfaces 62a and 64a of the first and second clutch plates, respectively, and have two to four straight or spiral protrusions. As shown, the teeth 56, 57 are provided symmetrically in the form of two narrow straight lines. This allows the first and second clutch plates 62 and 64 to engage in torque transfer with each other, such as engagement clutches, even when the treatment 18 is placed in the operating position when the first stirring shaft 36 is at an arbitrary angle. To make it possible. Preferably, the portion of each tooth 56, 57 facing the counter clutch plate is pointed. Since the first and second stirring shafts 36 and 38 rotate at a considerably low speed, the physical shock at the moment of clutch connection is not a big burden.

According to the present embodiment, the center shaft 70 protrudes from the hub 42 in the direction opposite to the hub shaft 46. The center shaft 70 is connected to the drive motor 60 and may be inserted into the center hole 74 of the drive shaft 72 installed in the outer housing 4. The drive shaft 72 is provided on the frame through the ball bearing 76 and is provided at the center of rotation of the flange 78 integrally connected to the drive shaft 72. The center hole 74 and the center shaft 70 are means for preventing the center of rotation of the first stirring shaft 36 from being disturbed.

The discharge port 80 is provided in the bottom of the processing chamber 18, and this discharge port 80 can be selectively opened and closed. As a means for opening and closing the discharge port 80, a worm 82, a first worm wheel 84, and a hatch member 88 fixed integrally with the first worm wheel 84 are rotated by a worm motor. do. The hatch member 88 is composed of a bottom plate 90 having the same curvature as the bottom of the treatment box 18 and a side plate 92 on which the first worm wheel 84 is installed. When the worm 82 rotates the first worm wheel 84, the hatch member 88 selectively opens or closes the discharge port 80 while pivoting about the rotation center of the first worm wheel 84. After being dried, the food waste discharged through the discharge port 80 is directly fed to the grinding roll 94. The rod-shaped grinding roll 94 having a gear in cross section is generally used in a conventional grinding machine. The food waste in the pulverized state passing through the grinding roll 94 is accumulated in a tray 96 installed below. In this way, the volume of food waste is reduced again.

According to the embodiment of the present invention, two discharge ports 80 and two hatch members 88 are installed in one processing box. The second worm wheel 86 is engaged with the first worm wheel 84 so as to be rotated by only one worm motor. Therefore, the two hatch members 88 are simultaneously started by one worm 82 and a worm motor. In this way, the crushing unit is further installed under the treatment box 18, and the dried food waste is pulverized and discharged in a state where the volume is further reduced.

The worm 82 and the first and second worm wheels 84 and 86 may be installed in the treatment box 18, and sometimes may be installed inside the outer housing 4 using the clutch means as in the above embodiment. It may be.
