Description

  The present invention relates to a dust collector with a sediment discharge function capable of selectively discharging soil and sand swept together with garbage.

In general, as shown in Patent Document 1, the dust collector is provided with a sweeping port for sweeping the dust on the front surface, and the dust collected by the scissors is swept into the interior from the sweeping port. . At this time, in the case of dust collectors used outdoors, the earth and sand are often swept together with the garbage, and the dust mixed with the earth and sand cannot be discarded as it is in a waste bin, so it is necessary to separate the garbage from the earth and sand. There is.
Conventionally, in such a case, it is common to grab garbage by hand and take it out of the dust collector, throw it away into a waste bin, and throw away the remaining earth and sand on the ground.
Japanese Utility Model Publication No. 6-39631

  However, the conventional treatment method described above is not only dirty and unsanitary, but also a part of the grabbed garbage is easily dropped and scattered around, and fine dust and earth and sand are completely removed. Separation took time and effort and was inefficient.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a dust collector with a sediment discharge function capable of easily and efficiently separating and discharging soil and sand swept together with waste.

In order to achieve the above object, the dust collector of the present invention comprises a box-type dust collection box having a sweeping port for sweeping dust on the front surface, and a handle attached to the dust collection box. The dust box has a trapezoidal box bottom wall, a box rear wall rising from the rear end of the box bottom wall, left and right box side walls rising from the left and right ends of the box bottom wall, and the box rear wall and Earth and sand swept into the dust collection box at a corner portion having a box upper surface wall continuous with the upper end portion of the box side wall and having a portion where the box upper surface wall and the box rear wall of the dust collection box are continuous A plurality of discharge holes having a long hole shape for separating and discharging waste from the box are formed so as to cross the corner portion from the box top wall side to the box rear wall side. To do.

In the present invention, preferably, the handle is formed at an upper end of a support column extending upward from the upper wall of the box, and a grip portion is formed at an intermediate position of the support column.

  Furthermore, in this invention, it can comprise so that a collar can be attached to the said handle so that attachment or detachment is possible.

  The dust collector with earth and sand discharge function of the present invention has a discharge hole for discharging earth and sand in the dust collection box. By tilting the dust collection box so that this discharge hole occupies a low position, Sediment having a large specific gravity and a small diameter is discharged to the outside through this discharge hole, and only the dust remains in the dust collection box. Therefore, there is an advantage that only the earth and sand can be separated from the waste easily and efficiently and discharged to the outside.

  FIG.1 and FIG.2 shows one Embodiment of the dust collector with a sediment discharge function based on this invention. The dust collector 1 includes a box-shaped dust collection box 10 having a sweep port 11 for sweeping dust on the front surface, and a handle 12 attached to the upper surface of the dust collection box 10, and a bowl 2 (FIG. 3), the dust collected in step 3) is swept into the dust collection box 10 from the sweep port 11.

  The dust collection box 10 is made of a material such as metal or hard synthetic resin, and when viewed from above, the dust collection box 10 has a substantially trapezoidal shape that gradually becomes wider toward the front side. The sweeping port 11 is formed on the front surface of the box, and a portion other than the sweeping port 11 includes a substantially trapezoidal box bottom wall 13, a box rear wall 14 rising from the rear end of the box bottom wall 13, and the above The box bottom wall 13 is surrounded by left and right box side walls 15, 15 rising from the left and right end portions of the box bottom wall 13, and the box rear wall 14 and the box top wall 16 connected to the upper ends of the box side walls 15, 15.

  The sweep port 11 is formed so as to be inclined so that the bottom side protrudes forward from the upper side by inclining the front end portions of the left and right box side walls 15, 15 substantially obliquely downward. Yes. A spatula 18 made of synthetic resin for facilitating sweeping of dust is attached to the bottom of the sweep port 11, that is, the leading edge of the box bottom wall 13 of the dust collection box 10.

  The dust collection box 10 is formed with a discharge hole 20 for separating and discharging the earth and sand swept together with the dust in the dust collection box 10. The discharge hole 20 may basically be formed at a position different from that of the sweep port 11, but earth and sand or fine dust is inadvertently generated from the discharge hole 20 while the dust collector 1 is being carried. In order to prevent leakage and scattering, it is desirable to form not at the box bottom wall 13 but at a position higher than the box bottom wall 13. Examples of such places include the box rear wall 14, the box side wall 15, or the box upper wall 16, preferably the box rear wall 14 and / or the box side wall 15. Preferably, the corner portion 21 close to the upper surface of the rear end portion of the dust collection box 10 where the box rear surface wall 14 and the box upper surface wall 16 are connected, or the box rear surface wall 14 and the box side wall 15 are connected. The corner portion 22 near the rear end side surface of the dust collection box 10 or the corner portion 23 near the upper surface of the side end portion of the dust collection box 10 where the box side wall 15 and the box top wall 16 continue, It is to be formed at the corner portions 24 at both end portions on the upper surface of the rear end portion of the dust collection box 10 that is the boundary between the face walls 14, 15, 16. In the illustrated embodiment, a plurality of discharge holes 20 are formed in the corner portion 21 near the upper surface of the rear end portion of the dust collection box 10 among the corner portions described above.

  The discharge hole 20 may have any shape, such as a circle, a rectangle, or a slit shape, as long as it can selectively discharge the earth and sand having a small particle size as waste. The discharge hole 20 in this embodiment is a vertically long hole extending in the direction of longitudinally cutting the corner portion 21 from the rear end portion of the box upper surface wall 16 to the upper end portion of the box rear surface wall 14. 20 are formed in parallel in the left-right direction of the dust collection box 10.

  Further, the handle 12 is formed at the upper end of a support column 25 attached upward to the center position of the front end of the box upper surface wall 16 in the dust collection box 10 and extends sideways toward the front side of the dust collection box 10. ing. The front end portion of the handle 12 is reinforced by the support frame 26 by being connected to an arch-shaped support frame 26 attached to the front end portion of the box upper surface wall 16. A horizontal frame 27 for reinforcement is also hung on an intermediate position with respect to 25.

A recess 28 is formed at a position on the front side of the connecting portion with the handle 12 in the intermediate portion of the support frame 26, and a pair of left and right holding arms 29 that open and close elastically inside the recess 28, As shown in FIG. 3, the handle 30 of the heel 2 is elastically held between the holding arms 29 and 29, so that the heel 2 can be detachably mounted and stored as shown in FIG. It has become.
The cocoon 2 has a rod-shaped handle 30 attached to a tip 31 for wiping, and has the same configuration as the known cocoon 2.

  The dust collector 1 having the above-described configuration is similar to the conventional general dust collector 1 and sweeps the dust collected by the scissors 2 from the sweep port 11 into the dust collection box 10 and disposes it as a waste bin. It is carried to the place and thrown away. At this time, when the dust collector 1 is used outdoors, the earth and sand are swept together with the dust into the dust collection box 10. In this case, as shown in FIG. By tilting 10 so that the discharge hole 20 occupies a low position, earth and sand having a specific gravity larger than dust and having a small diameter are discharged to the outside through the discharge hole 20, and only the dust remains in the dust collection box 10. Carry the garbage to the disposal site and throw it away. In this case, in particular, since the discharge hole 20 is formed in the corner portion of the dust collection box 10, when the dust collection box 10 is tilted, the corner portion becomes a valley bottom and heavy earth and sand are easily collected. It can be easily and efficiently separated from waste and selectively discharged to the outside.

  As described above, when the dust collector 1 is tilted when discharging earth and sand, if the angle is so large that it is difficult to tilt the handle 12 with the handle 12, the grip portion 25a formed at the intermediate position of the column 25 is provided. It can also be held and tilted.

  Further, when the box rear wall 14 is curved in a convex shape toward the outside, the discharge hole 20 can be formed at a position at an intermediate height of the box rear wall 14. In this case, as in the illustrated embodiment, the earth and sand can be discharged just by tilting the dust collection box 10 slightly smaller than when the discharge hole 20 is formed in the corner portion 21 near the upper surface of the rear end of the dust collection box 10. It can be collected at the hole 20 and discharged.

It is a perspective view at the time of seeing the dust collector which concerns on this invention from the front side. It is a perspective view at the time of seeing the said dust collector from the back side. It is a perspective view at the time of attaching a tub to the said dust collector. It is a side view of dust removal which shows the method of discharging earth and sand.
