Is rotatably provided. These first and second rollers 10 and 11 are slidably fitted along the inner wall of the guide groove member 8.

As shown in FIG. 7, on the front side and the upper side of the dust input box 6, there is a partition plate 7 that extends in the vertical direction along the guide groove member 8 and forms a dust pushing port 7a that communicates with the rear opening 4 downward. It is provided. A concave groove 7b extending vertically is recessed in the partition plate 7.

On the other hand, as shown in FIG. 3, the sliding plate support shaft 12 is inserted into the support portions 18 provided at the left and right ends of the upper back surface of the sliding plate 9. The sliding plate support shaft 12 matches the sliding distance of the sliding plate 9 and protrudes outward from the inside of the dust input box 6 beyond the sliding opening 19 formed in the side wall 6b of the dust input box 6. Is located in.

Between the sliding plate support shaft 12 projecting outward from the side wall 6b of the dust input box 6 and the lower portion of the dust input box 6, a slide provided on the outside of the dust input box 6 along the inclination direction of the guide groove member 8. The moving cylinder 13 is connected. The sliding plate 9 is reciprocated up and down along the guide groove member 8 by the expansion and contraction operation of the sliding cylinder 13.

As shown in an enlarged manner in FIG. 1, the push plate boss portions 9a provided at the left and right end portions of the sliding plate 9 have one end on the front side of the push plate 15 that extends to the full width of the dust input box 6. It is supported so that it can swing back and forth. An intermediate boss portion 9c extending in the left-right direction is provided between the push plate boss portions 9a. The tip of the push-in plate 15 is slightly bent toward the front. A swing cylinder 14 is connected between the connecting portion 15a projecting from the back surface of the push plate 15 and the support portion 18 provided on the upper portion of the back surface of the sliding plate 9, and the swing cylinder 14 expands and contracts. The push-in plate 15 is swung back and forth.

Although not shown, a discharge plate formed in the dust storage box 3 having a size substantially the same as the width and vertical height of the dust storage box 3 is slidably arranged in the front-rear direction. It may be made to slide back and forth in the storage box 3.

The sliding plate 9 extends vertically along the partition plate 7 (guide groove member 8) and has a front wall 21 facing the partition plate 7. A gap is secured between the front wall 21 and the partition plate 7 to the extent that the vertical movement of the sliding plate 9 is not hindered. Then, at the lower end of the front wall 21, an inclined wall 22 is formed which extends downward from the extension line of the front wall 21 so as to incline forward and whose lower end is continuous with the intermediate boss portion 9c. Ideally, the inclined wall 22 is continuous on the tangent line of the intermediate boss portion 9c , but may be slightly deviated from the tangent line as in the present embodiment. In short, it is important to prevent the formation of the corner portion 7a'where dust is easily clogged as in the prior art shown in FIG. 8 as much as possible.

The front wall 21 of the sliding plate 9 is formed with a ridge 23 that fits into the concave groove 7b of the partition plate 7. The lower end of the ridge 23 is coupled to the inclined wall 22 and to the intermediate boss portion 9c .

The dust loading device 20 configured in this way collects dust through the loading port 6a in a state where both the sliding cylinder 13 and the swinging cylinder 14 are extended and the sliding plate 9 is in the ascending end position. The loading operation is started by throwing it into the cylinder 6 and turning on a start switch (not shown).

First, the swing cylinder 14 is degenerate and the push plate 15 is reversed to reach the reverse end position (reversal step). After that, the sliding cylinder 13 is degenerated and the sliding plate 9 is lowered, and the pushing plate 15 is moved to the lowering process accordingly. Next, when the push-in plate 15 reaches the lowering end position, the swing cylinder 14 is extended to swing the push-in plate 15 forward to shift to the compression step. Then, when the push-in plate 15 swings to the frontmost position, the sliding cylinder 13 is extended to raise the push-in plate 15 to shift to the ascending step, and when the push-in plate 15 reaches the ascending end position, a series of steps are taken. End the loading operation. As a result, the dust loading operation can be repeated with each step of reversing, lowering, compressing, and raising as one cycle. In this embodiment, the inclined wall 22 is set so as not to come into contact with the lower end of the partition plate 7 at the ascending end position.

Then, when the sliding plate 9 reaches the ascending end position, dust may be caught between the lower end of the partition plate 7 and the intermediate boss portion 9c.

However, in the present embodiment, the inclined wall 22 provided at the lower end of the front wall 21 of the sliding plate 9 covers the lower end of the front wall 21 and the intermediate boss portion 9c in a smoothly continuous state, so that the lower end of the partition plate 7 is covered. Even if dust is sandwiched between them, it is difficult for the dust to get stuck between the intermediate boss portion 9c and the lower end of the partition plate 7.

Further, as in the present embodiment, the ridges 23 are also provided with recessed grooves 7b and ridges 23 on the partition plate 7 and the front wall 21 of the sliding plate 9, respectively, to prevent dust from sticking to the ridges 23. At the lower end of the wall, the inclined wall 22 effectively prevents clogging of dust.

As described above, according to the dust loading device 20 according to the embodiment of the present invention, clogging of dust between the partition plate 7 and the intermediate boss portion 9c can be prevented extremely effectively.
