Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inlet opening/closing device for a powder transport vehicle.

Conventionally, as shown in FIG. 1, the inlet opening/closing device provided at the top of the powder storage container is provided so that it can rotate upward with a pair of slide rails 01, 01 constantly biased upward by a spring 02. , an input port cover 03 is slidably provided between the pair of slide rails 01, 01, and each of the slide rails 01, 0
1 are connected by a shaft 04.

The shaft 04 has mold engagement frames 05, 05.
are installed vertically in pairs on the left and right, and these engagement frames 05, 0
Hooks 06, 06 that can engage with the engagement frames 05, 05 at the time of closing the input port lid 03 are provided at positions adjacent to 5, and the hooks 06, 06 are connected to the support members 07, 06 on the powder container. The hook 0 is fixed to the shaft 08 installed between the hook 07 and the spring 09 provided between the hook 06 and the powder container.
6, 06 are always urged to the engagement position with the engagement frames 05, 05.

However, with the above structure, when the powder is put into the powder container, the powder may scatter onto the top surface of the container. Therefore, when trying to clean the scattered powder, it is difficult to remove the hook. Since the attached shaft is close to the upper surface of the powder container, the shaft and supporting member get in the way of cleaning, making cleaning work very troublesome.

In order to solve the above-mentioned drawbacks, the present invention uses a pipe as the member connecting the pair of slide rails, and a lock shaft for fixing the input port cover to the powder container is provided in the pipe. .

The following embodiment will be explained with reference to the drawings. 1 is the vehicle body 2.
The container 1 is equipped with an inlet opening/closing device 3 at the top of the container 1. Further, behind and above the container 1, there is a screw conveyor transfer device 4 for transferring the powder and granular material in the container 1 to a silo or the like.
is provided.

Next, to explain the inlet opening/closing device, 5.
Reference numeral 5 denotes a pair of slide rails having a U-shaped cross section and extending laterally with the input port 6 in between.
5 are provided so that their openings face each other.

One end of the slide rails 5, 5 is pivotally supported by the container 1 via brackets 7, 7 so as to be able to rotate upwardly, and the other end is connected to each other by a pipe 9 via brackets 8, 8 extending upward. ing. Furthermore, springs 10, 10 are provided approximately in the center of the slide rails 5, 5 to constantly bias the slide rails 5, 5 upward between the slide rails 5, 5 and the container 1.

Reference numeral 11 denotes an input port lid that is somewhat larger than the input port 6 provided between the pair of slide rails 5, 5;
On both sides of the input port lid 11 are side portions 1 having a U-shaped cross section.
2, 12 are formed, and the opening portions of the side portions 12, 12 are provided so as to face the opening portions of the respective slide rails 5, 5. In addition, on the back side of the input port lid 11, the input port lid 11 is pressed by the edge of the input port 6.
A sealing member 13 for sealing the input port 6 and the input port 6 edge is fixed in the same shape as the input port 6 edge.

Between the side parts 12, 12 of the input port lid and the slide rails 5, 5, there are rods 14, 14 that roll on rods 14, 14 fixed in the slide rails 5, 5 at the front part of the input port lid 11, as shown in FIG. Rollers 15, 15
is pivotally supported on the side parts 12, 12 side, and the input port lid 11
At the rear, a roller 1 rolls on rods 16, 16 fixed in side parts 12, 12 as shown in FIG.
7 and 17 are pivotally supported on the slide rails 5 and 5, and the input port cover 11 is slidably supported by the slide rails 5 and 5.

As shown in FIG. 6, inside the pipe 9 connecting the pair of slide rails 5, 5, a pair of lock shafts 19, 19 having large diameter portions 18, 18 having approximately the same diameter as the inner diameter of the pipe 9 at their base ends are slid. A lock shaft 1 is provided movably between the large diameter portions 18 and 18.
A spring 20 is interposed so as to constantly bias the tips of the pipes 9 and 19 in the direction of protrusion from the end of the pipe 9.

Triangular mounting members 21, 21 are provided at the bases of the pair of lockshafts 19, 19, and a portion of the mounting members 21, 21 protrudes from elongated holes 22, 22 of an appropriate length formed in the pipe 9. The protruding portion is connected by a central arm 24 having a handle 23 serving as an operating means and connecting arms 25, 25 provided at both ends of the central arm 24, and is normally attached to the mounting member 2.
1 and 21 come into contact with one end of the elongated holes 22 and 22.
9 and 19 are made to protrude from the pipe 9, and the spring 20 is compressed by pulling the handle 23 as shown by the dashed line in FIG.
2, 22 until it comes into contact with the other end, and the lock shaft 19, 19 can be retracted into the pipe 9. Reference numerals 26 and 26 indicate engagement members erected on the container 1 facing both ends of the pipe 9, and the engagement members 26 and 26 have tapered portions 27 and 27 that widen upward and lock shafts 19 and 19. vertical parts 29, 29 having holes 28, 28 through which the pipe 9 can be inserted;
9, 19 are pushed in by the tapered parts 27, 27, and when the input port cover 11 closes the input port 6, the lock shafts 19, 19 are inserted into the holes 28, 28 and come to engage with the engaging members 26, 26. ing.

30 is a handle provided on the input port lid 11.

The present invention has the above-mentioned configuration. Next, the operation will be explained. First, when opening the input port cover 11, the third
When the handle 23 is pulled from the state shown by the solid line in FIG. 6 and the solid line in FIG. 6 to the dashed line in FIG. 6 against the spring 20,
The lock shafts 19, 19, which had been engaged with the engaging members 26, 26, are retracted and the engagement is released.

When the engagement is released, the springs 10, 10 provided on the pair of slide rails 5, 5 move the input port cover 11 to the fourth position along with the slide rails 5, 5.
The sealing member 1 had been rotated upward from the solid line position to the dashed-dotted line position in Figures 7 and 8 and was being pressed.
3 will be released.

Thereafter, the input port 6 can be opened by sliding the input port cover 11 along the inclined slide rails 5, 5 in the direction of the arrow in FIGS. 4 and 5 to the position indicated by the two-dot chain line.

Next, at the end of the loading work of powder and granular material, the loading port 11
When closing the inlet port cover 11,
Pull it up to above the input port 6 along the slide rails 5, 5 in the opposite direction to the direction of the arrow in the figure.

Thereafter, when the pipe 9 is pushed down from the dot-dashed line position to the solid line position in FIG. With the seal member 13 pressed against the edge of the input port 6, that is, with the input port 6 closed, the lock shafts 19, 19 are inserted into the holes 28, 28 of the engagement members 26, 26, and the lock shafts 19, 19 are inserted into the holes 28, 28 of the engagement members 26, 26. The input port 6 is engaged and the closed state of the input port 6 is maintained.

As described above, the present invention connects a pair of guide rails that support the input port cover with a pipe, and provides a lock shaft slidably within the pipe, so that when the input port cover closes the input port, the lock shaft protrudes and moves toward the container side. As a result, the device for fixing the input port in the closed state has become extremely compact, and there are no parts that get in the way when cleaning scattered powder and granules, making it easier to clean. It can be done easily.
