あつた。 In recent years, stirring devices that stir two or more types of powder or granular materials that need to be mixed, such as powdered materials or metal powder used as material for feed or sintered metal, have been developed by rotating a stirring drum containing the materials to be mixed. It is constructed so that stirring and mixing operations can be carried out efficiently by swinging it like a seesaw at the same time. The outer circumferential surface of the stirring drum is held between both sides by presser rollers rotatably attached to the pillars so that the stirring drum does not fall off from the stirring device during rocking.
However, when removing the stirring drum from the stirring device for cleaning, or when mounting another stirring drum containing materials to be mixed on top of the stirring device,
Each time, the above-mentioned presser rollers were removed from contact with the stirring drum, and the stirring drum itself was lifted above the presser rollers and then lowered to the ground or placed on the stirring device, so the stirring drum was lifted,
When lowering the suspension, it is extremely troublesome to separate the plurality of presser rollers from the stirring drum individually.Moreover, since the presser rollers are attached to the upper ends of the columns, the stirring drum cannot be pulled away from the stirring drum. It is not possible to load or remove the heavy stirring drum unless it is hoisted higher, so raising and lowering the heavy stirring drum is very time-consuming and cannot be done quickly and easily. When placing the stirring drum on the drum, it must be passed between the presser rollers, so if this work was not done carefully, there was a risk that the stirring drum would collide with the presser rollers and cause damage. In addition, if the part of the outer circumferential surface of the stirring drum that contacts the presser roller is distorted, or if the stirring drum is affected by vibrations caused by the movement of the mixed material during operation, or if the stirring drum in particular is shaken. The mixed material also moves repeatedly in the same direction every time it is tilted at a certain angle due to movement, so if the mixed material is metal powder with a large specific gravity, the end of the stirring drum on the opposite side to the tilting direction will always be affected by the weight of the mixed material during rocking. If the stirring drum jumps up in the direction of inclination, the stirring drum collides with the presser roller in such a way that it pushes up, and the impact force damages the presser roller and the pillars that support it, causing the stirring drum to become unsupported. There was a drawback that the stirring drum could not be supported safely and reliably.

8 is a roller support rod 2 using the long hole 30 as a guide.
It is pulled upward in the same manner as 6 and 26'.
Furthermore, even if the roller support rods 26, 26' are pulled up to the position indicated by the two-dot chain line and then the operating handle 42 is released, the worm wheel 47 is still engaged with the worm gear 46, so that the roller support rods 26, 26' will not fall down from the position indicated by the two-dot chain line. There isn't. Further, since the presser roller 36 is cut off from contact with the stirring drum 19, the roller mounting brackets 33, 33' are attached to the spring 39 around the support shaft 35 as shown by the two-dot chain line in FIGS. It is pressed into a V-shape. The stirring drum 19 is moved by the separation of the presser roller 36.

阻止せしめて撹拌ドラム１９の運転を円滑に行な
わせる。 When the presser roller 36 is brought into contact with the stirring drum 19, the operating handle 42 is turned in the opposite direction to the above-mentioned direction, and the roller support rods 26, 2 are moved by the rotating shaft 24.
6' to the solid line position in Fig. 2, and presser roller 3.
6 is brought into contact with the stirring drum 19. At this time, as shown by solid lines in FIG. 2, the roller mounting brackets 33, 33' are placed in a horizontal state with the presser roller 36 in contact with the stirring drum 19, and the rollers of the roller mounting brackets 33, 33' are Mounting tool 37
A gap is created between the upper end surface of the side and the roller support rods 26, 26'. After that, tighten the tightening handle 32 to attach the reinforcing plate 28 to the pillars 23 and 2.
Fixed at 3'. In this state, the stirring drum 19 is rotated and oscillated by the electric motors 10 and 14. On this occasion,
A part of the circumferential surface of the stirring drum 19 that comes into sliding contact with the presser roller 36 may be uneven, or the stirring drum 19 may have an uneven surface.
The end of the stirring drum 19 opposite to the inclined side was about to be lifted in the inclined direction by the force generated when the mixed material moved from one end to the other end in the stirring drum 19 due to the swinging movement of the stirring drum 19. Even if force is applied to the presser roller 36 due to the irregular rotation or rocking motion of the stirring drum 19 itself, the presser roller 36 is always buffered by the spring 39 and is not connected to the worm gear 46. The roller support rod 2 does not damage the meshing part with the worm wheel 47 at all, and even if the stirring drum 19 moves irregularly, it is reliably supported by the spring action, resulting in irregular operation.
6, 26', the presser roller 36, etc. are prevented from being damaged, and the stirring drum 19 is allowed to operate smoothly.

れた効果を有するものである。 As mentioned above, the present invention has a plurality of presser rollers that support the stirring drum that are simultaneously brought into contact with and separated from the stirring drum using the operation handle, and that these presser rollers are individually supported by springs so that the stirring drum can be moved while the stirring drum is in operation. This system absorbs the impact force applied to the presser roller, thereby preventing damage to the presser roller, etc., and supports the stirring drum reliably and stably. This is completely different from the system in which the presser rollers are brought into contact with the stirring drum in a way that they are clamped from the ground, and the contact with the stirring drum is released individually.In this case, a plurality of roller support rods each having a plurality of presser rollers are operated by a handle. Since it can be brought into contact with and separated from the stirring drum in one motion, handling of the presser roller can be performed quickly and easily. In addition, the roller support rod equipped with the presser roller is structured so that when the handle is operated, the roller support rod is positioned directly above the column that supports the roller support rod via the rotation shaft, so it is easy to lift and suspend the stirring drum. When lowering the stirring drum, it is not necessary to lift it above the presser roller, but it is only necessary to lift it slightly above the friction wheel, so that the stirring drum can be quickly, easily and safely lowered and raised from the base plate. Furthermore, since the presser roller is separately attached to the roller support rod via a spring, even if an impact force that pushes up the presser roller is applied by the stirring drum while the stirring drum is in operation, this impact force will be suppressed. Since it is absorbed by the above spring, there is no damage to the presser roller, the roller support rod, or the worm wheel that rotates the roller support rod when the handle is operated, and the stirring drum can be supported in a stable state at all times. I can do it. In addition, since the press roller is attached to the roller support rod with the stirring drum sandwiched from above on both sides of the top of the stirring drum, in addition to the effect of holding the press roller through the spring, the stirring drum is simply held upward. Since the structure is such that the stirring drum is supported by being held in place rather than being pressed against it, it has the advantage of being able to support the stirring drum reliably and safely when it rotates and oscillates. Moreover, since the roller support rod is connected to the column by a reinforcing plate, it is firmly held by the reinforcing plate even if force is applied to the roller support rod through the presser roller when the stirring drum swings. Therefore, it has many excellent practical effects, such as being able to increase the swing angle of the stirring drum in order to increase the stirring and mixing efficiency.
