The first engaging element 31 and the second engaging element 32 may be provided in the slider 21, and the first guiding groove 34 and the second guiding groove 35 may be provided in the stand main body 20.

  As shown in FIG. 2, the cyclone hopper 2 is formed by joining the left and right halves, and the combined portion of both halves extending vertically forms a projecting portion 15 projecting outward. The protrusion 15 is fitted into a through hole 29 provided in the inner peripheral edge of the support plate 22 having a substantially annular shape, and the cyclone hopper 2 can be detached upward by the through hole 29 of the support plate 22. It is supported so as not to rotate around the axis.

  The collection container 3 is connected to the discharge port 12 of the cyclone hopper 2 and collects the removed dust. The stand 5 supports the cyclone hopper 2 so as to be movable up and down via a slider 21 and is detached from the collection container 3 when moved upward. The collection container 3 has a container main body 51 for storing the dust and a lid body 52 that closes an upper opening of the container main body 51 so as to be openable and closable. The lower end of the cyclone hopper 2 is disposed on the lid body 52. The parts are connected so that they can be inserted and removed.

  As shown in FIG. 5, a straight portion 27 having a uniform outer diameter that is inserted into the insertion hole 53 of the lid 52 is formed at the lower end portion of the lower portion 17 of the cyclone hopper 2. The insertion hole 53 through which the lid 52 passes is also formed with a straight hole portion 53b correspondingly.

The seal member 25 is provided with a seal member 25b made of a rubber O-ring or an annular cushioning packing on the lower surface 25a of the annular main body 25a. As a result, when the lower end portion of the lower portion 17 of the cyclone hopper 2 is inserted into the insertion hole 53 of the lid body 52, the seal member 25 comes into contact with the upper surface 54 of the peripheral edge portion of the insertion hole 53 in the lid body 52. Thus, the insertion hole 53 of the lid body 52 is sealed without a gap, so that dust collected from the cyclone hopper 2 to the collection container 3 can be prevented from scattering to the outside. Further, the impact when the cyclone hopper 2 comes into contact with the lid 52 of the collection container 3 can be reduced, and the impact sound is also reduced.

Next, the handling and operation of the dust separation processing apparatus 1 will be described.
The suction force of the suction pump P built in the dust collector 7 shown in FIG. Is done. The intake air becomes a vortex in the cyclone hopper 2, and high-density heavy particles move downward along the inner surface of the conical lower portion 17 while swirling by centrifugal force, and fall from the discharge port 12 to the lower collection container 3. To do. Fine particles such as dust having a low density rise on a rising swirl vortex formed in the center of the cyclone hopper 2 and are discharged to the outside from the exhaust port 11 at the upper end of the cylindrical portion. Thus, since air from which heavy particles have been separated and removed is introduced into the dust collector 7 of FIG. 1, the filtering burden of the dust collector 7 is reduced, and therefore the occurrence of clogging of the filter unit FU of the dust collector 7 is delayed. The dust processing efficiency is improved by that amount.

  After the dust processing by the dust separation processing apparatus 1, the collection container 3 is detached from the dust separation processing apparatus 1 by the following operation, and the dust in the collection container 3 is discarded.

  FIG. 4A shows the same dust treatment set state as FIG. 2, the cyclone hopper 2 is in a vertical posture, and the engagement elements 31, 32 of the stand body 20 are respectively guided grooves 34 of the slider 21, The upper end of 35 is engaged.

  FIG. 4B shows a state where the cyclone hopper 2 is lifted in order to disengage the cyclone hopper 2 from the collection container 3. When the front portion 22a of the support plate 22 is lifted with the finger F in the R1 direction, the slider 21 rises, and the first engagement element 31 and the second engagement element 32 are longitudinal grooves of the first guide groove 34 and the second guide groove 35. As shown in FIG. 5, the first guide groove 34 and the second guide groove 35 move to the lower end portions while being guided by the guide 36. Further, since the front portion 22a on which the operating force of the finger F acts on the first engagement element 31 is displaced forward, the lifting force acting on the front portion 22a of the support plate 22 is applied to the slider 21 on the first engagement element. Since the tilting moment about 31, that is, the moment at which the lower part of the slider 21 tries to advance forward from the upper part is given, the second engagement element 32 naturally occurs when it reaches the lower end of the vertical groove 36 of the second guide groove 35. It advances into the front-rear groove 37, stops by being fitted into the tilt stop 39 at the rear end of the front-rear groove 37, and assumes the posture shown in FIG. Here, the ascending stroke of the cyclone hopper 2, that is, the vertical lengths of the first guide groove 34 and the vertical groove 36, is such that the straight portion 27 at the lower end of the cyclone hopper 2 comes out from the lid 52 of the collection container 3 upward. It is set to a sufficient length.

  In this way, since the cyclone hopper 2 smoothly inclines backward, the cyclone hopper 2 is fitted into the tilt stop portion 39 of the front and rear grooves 37 of the second guide groove 35 and stopped, so that the upper limit position of the cyclone hopper 2 is known and the cyclone hopper of FIG. The lower end portion of the lower portion 17 of FIG. 2 and the collection container 3 are further separated by the inclination, so that the cyclone hopper 2 does not get in the way when the collection container 3 is taken out, and the collection container 3 can be taken out easily. In this way, the cyclone hopper 2 can be brought into the detached position by a simple one-touch operation. Note that the tilt stop portion 39 may be omitted, and even in that case, the upper edge of the front and rear groove 37 of the second guide groove 35 is formed by the weight of the cyclone hopper 2 as shown in FIG. The rearward tilt posture of the cyclone hopper 2 is maintained by being pressed against the top.

  In the posture of FIG. 3 in which the cyclone hopper 2 is tilted backward, the cyclone hopper 2 may return to the original vertical posture by receiving an impact force from the outside. In this case, as shown in FIG. 4C, the slider 21 rotates around the first engagement element 31 and fits in the intermediate stop portion 38 in the front and rear groove 37 of the second guide groove 35 to tilt backward. The posture becomes a little closer to the vertical posture than the posture and rests. Thus, the second engaging element 32 is prevented from suddenly entering the longitudinal groove 36 and the cyclone hopper 2 together with the slider 21 being prevented from descending.

  Unlike after the dust treatment described above, when the dust container is discarded, the collection container 3 is returned to the stand base 23 and the cyclone hopper 2 is set to start the dust treatment. 4 Operation is performed in the procedure of (B), (C), (A). In FIG. 4B, since the cyclone hopper 2 is inclined rearward, the collection container 3 can be easily placed on the stand base 23. Next, when the support plate 22 is pushed backward R <b> 2 by the force of the light finger F, the second engagement element 32 is detached from the tilt stop portion 39, and the front and rear grooves 37 of the second guide groove 35 with respect to the second engagement element 32. Moves rearward, and the second engagement element 32 is fitted into the intermediate stop portion 38 of the front-rear groove 37 and rests. Accordingly, it is possible to prevent the second engagement element 32 from entering the vertical groove 36 of the second guide groove 35 at a stretch with a small pushing force and the cyclone hopper 2 from dropping suddenly. When the support plate 22 is further pushed in the R2 direction from this resting state, the second engagement element 32 is detached from the intermediate stop portion 38, naturally enters the longitudinal groove 36 from the front and rear grooves 37, and reaches the upper end of the longitudinal groove 36. To lock automatically. Thereby, the cyclone hopper 2 is set in a vertical posture, and its lower end is inserted into the collection container 3.

  The insertion hole 53 of the lid body 52 is formed with a guide surface 53 a that is widened upward at the top, whereby when the straight portion 27 at the lower end of the cyclone hopper 2 is inserted into the insertion hole 53. Even when the collection container 3 is not concentric with the cyclone hopper 2, the straight container 27 enters the straight hole 53 b below the insertion hole 53 while being guided by the guide surface 53 a, so that the collection container on the stand base 23. 3 moves, and the collection container 3 is positioned.

  Thus, after separating and removing the dust from the intake air, the cyclone hopper 2 can be detached from the collection container 3 simply by moving the cyclone hopper 2 upward, and the lid 52 provided toward the collection container 3 is attached to the cyclone hopper 2. Since the lower end portion is connected so as to be able to be inserted / removed, it is not necessary to attach / remove the connecting member when attaching / detaching the cyclone hopper and the collection container as in the prior art. It becomes easy and the operation | work which discards the dust in the collection container 3 becomes easy.

  In the above-described embodiment, the case where the work box 6 and the dust collector 7 are installed to perform the work has been described as an example. However, the present invention is not limited to this. It can be applied to any system that is connected to a suction machine and separates and removes dust from the intake air.
