Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust collector, and more particularly, to an internal structure of a dust box storage chamber.

[0002]

[Prior Art]

 The internal structure of the conventional dust collector is shown in FIG.

In FIG. 5, reference numeral 5 is a dust collecting filter, 10 is a dust box storage chamber, 10 a is a dust box outlet, 11 is an inner wall of the machine body, and a hopper frame for guiding dust falling from the filter 5 to the dust box 13, 12 Is a packing fixed to the bottom edge of the hopper frame 11.

15 is a link mechanism for lifting and lowering the dust box, which is located at the bottom of the dust box storage chamber 10 and rotatably attached to its four corners, 17 is a dust cover, and 20 is a lift for moving the link mechanism 15 up and down. A handle, 21 is dust, 26 is a connecting member for connecting the front and rear link mechanisms 15 and 15, and 27 is a tray for mounting a dust box.

In the above structure, the tray 27 for mounting the dust box is moved up and down by the four rotatable link mechanisms 15 by operating the lift handle 20.

Then, the dust box 13 is closely sealed to the packing 12 fixed to the bottom edge of the hopper frame 11 as the tray 27 is raised.

[0007]

[Problems to be solved by the device]

 The internal structure of the conventional dust collector is as described above, but in the past, the link mechanism 15 that lifts the dust box 13 and seals it with the packing 12 at the rim of the hopper frame is provided at the four corners of the bottom of the dust box storage chamber. Since a total of four sets are attached to the link mechanism 15, the number of parts such as the link body, the pin, the roller, and the small screw that constitute the link mechanism 15 increases, and it takes a lot of time to attach them. Instead, when the dust 21 accumulated in the dust box 13 is discarded, the dust box 13 having an increased weight has to be lifted and carried, which is troublesome to handle.

The object of the present invention is to reduce the number of parts of the dust collector as compared with the conventional one, to improve the efficiency of the assembling work, and to increase the weight when disposing of the dust accumulated in the dust box. It is an object of the present invention to provide an improved dust collector with a good handling of the dust box.

[0009]

[Means for Solving the Problems]

 The purpose is to have a dust box storage chamber in which the dust box can be pulled out freely, a hopper frame that guides the dust that falls from the dust collection filter to the dust box, a packing is fixed to the bottom edge of the hopper frame, and the dust box In a dust collector with a structure in which the dust box stored in the storage chamber is raised to seal tightly to the packing on the rim of the bottom of the hopper frame, in addition to attaching wheels to the dust box, the dust box storage chamber has a bottom rear side, A dust box guide plate having an inclined part that pushes the dust box up to raise the rear end side of the dust box and tightly seals it to the packing at the rim of the bottom of the hopper frame is provided, and at the outlet side of the dust box storage chamber, the dust box Raise the tip side to lift the pad on the rim of the bottom of the hopper frame. It is achieved by mounting the link mechanism for adhering the seal to Kin.

[0010]

[Action]

 In the above configuration, the operation of moving the dust box in and out is performed by the wheels attached to the dust box.

Then, when the dust box is pushed into the dust box storage chamber, the rear end side of the dust box rides up on the inclined portion of the dust box guide plate provided at the bottom rear side of the dust box storage chamber and rises to the hopper. It is closely sealed to the packing on the edge of the frame bottom.

Further, at this time, the tip side of the dust box is tightly sealed to the packing at the rim of the bottom of the hopper frame by operating the link mechanism attached to the outlet side of the dust box storage chamber.

【Example】

 Hereinafter, the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a partially longitudinal side view of a main part showing an embodiment of the present invention dust collector, and FIG. 2 is the entire dust collector of the present invention. FIG. 3 is a vertical sectional front view showing the configuration, FIG. 3 is a view corresponding to FIG. 1 with the dust box 13 pulled out, and FIG. 4 is an exploded perspective view of the bottom of the dust box storage chamber.

As shown in FIG. 2, the machine body 1 includes a motor 2, a fan 3, a casing 4, a dust collecting filter 5, an air tank 6, a pulse pipe 7, and the like.

A dust box storage chamber 10 is provided at the bottom of the machine body 1.

A hopper frame 11 for guiding the dust 21 falling from the filter 5 to the dust box 13 is provided on the inner wall of the machine body 1, and a packing 12 is fixed to the bottom edge of the hopper frame 11.

At the bottom inner side of the dust storage chamber 10, there is an inclined portion for pushing the dust box 13 to raise the rear end side of the dust box 13 and tightly sealing it to the packing 12 at the rim of the bottom of the hopper frame. A dust box guide plate 14 is provided.

Further, a link mechanism 15 is attached to the outlet side of the dust box storage chamber 10 to raise the tip side of the dust box 13 to closely seal the packing 12 at the rim of the bottom of the hopper frame. As shown in FIG. 4, it is composed of a handle base 18, a link body 19, pins 22, R pins 23, rollers 24, machine screws 25 and the like.

On the other hand, wheels 16 are attached to the bottom of the dust box 13.

In the figure, 8 is an air intake port provided on the side wall of the machine body 1, 9 is an air discharge port provided on the top plate of the machine body 1, 10a is a dust box outlet, 17 is a dust cover, and 20 is a link mechanism 15 It shows a lift handle that moves up and down.

The operation of the dust container having the above structure will be described.

When the dust box 13 is pushed into the dust box storage chamber 10, the rear end side of the dust box 13 rides up on the inclined portion of the dust box guide plate 14 provided at the bottom rear side of the dust box storage chamber 10 and rises, It is closely sealed to the packing 12 at the bottom edge of the hopper frame.

Next, when the lift handle 20 is pulled up, the link mechanism 15 rotates, the tip side of the dust box 13 rises along the roller 24, and is tightly sealed to the packing 12 at the rim of the bottom of the hopper frame.

On the contrary, when pulling out the dust box 13 from the dust box storage chamber 10, if the lift handle 20 is lowered, the wheels 16 land, so that it can be pulled out easily, and the dust box 13 can be run as it is. As a result, the dust 21 can be easily discarded.

In summary, according to the present invention, since the wheels 16 are attached to the dust box 13, the weight is increased when the dust box 13 is put in or taken out, particularly when the dust 21 accumulated in the dust box 13 is discarded. The operation of pulling out the dust box 13 can be easily performed.

Further, when the dust box 13 stored in the dust box storage chamber 10 is lifted up and tightly sealed to the packing 12 at the rim of the bottom of the hopper, the dust box 13 is located at the bottom rear side of the dust box storage chamber 10. A dust box guide plate 14 having an inclined portion for raising the rear end side of the dust box 13 by pushing is provided, and the front end side of the dust box 13 is raised to the hopper frame on the side of the outlet 10a of the dust box storage chamber 10. Since a link mechanism 15 for tightly sealing is attached to the packing 12 at the bottom edge, a total of four sets of link mechanisms 15 are attached to the four corners of the bottom of the dust box storage chamber as in the conventional dust collector shown in FIG. It is no longer necessary to open the link body, and the link body, The number of parts such as rollers, rollers, and small screws is reduced, and the efficiency of assembly work can be improved.

[0027]
