Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an opening/closing device for an input port in a powder transport vehicle.

(b) Prior Art FIGS. 1 and 2 show a conventional inlet opening/closing device, in which an inlet 02 is provided at the top of a powder container 01.
is provided, and the input port 02 is provided with an input port opening/closing device 0.
3 is provided.

(c) Problem to be solved by the invention When the lashing device 04 is released, the springs 0 provided on the pair of slide rails 05, 05
At 6,06, with slide rails 05,05,
The input port cover 07 is rotated upward to the position shown by the two-dot chain line.
After that, the input port 02 is opened by sliding the input port cover 07 along the inclined slide rails 05, 05 to the position indicated by the three-dot chain line, but the slide rails 05, 05 must be kept within the full width of the safety standards. There was a problem that the large input port 02 could not be fully opened because it could not be opened for a long time.

(d) Means for Solving the Problems The present invention solves the above-mentioned problems by rotatably providing a plurality of support leg arms on a frame provided with rails, and attaching the frame to the support arms. By providing a spring that urges upward, and providing a lashing device for lashing the input port lid between the input port lid and the powder container, the lashing device is released and the frame is moved upward by the spring. When moved, the input port is moved away from the position of the input port when closed and opened by a length a in FIG. 5, so that even if the input port is large, the input port can be fully opened.

(e) Operation When the lashing device is released, the support arm rotates due to the spring force, and the frame and the input port also move and stop at the position of length a.

Thereafter, by sliding the input port cover, the input port cover can be opened by an extra length a even if the slide amount is the same as before, and even if the input port is large, it can be fully opened.

(f) Example The following example will be explained with reference to the drawings. 1 indicates the vehicle body 2.
A powder container is mounted on the container 1, and the upper part of the container 1 has an inlet opening/closing device 3 for introducing powder and granules.
is provided.

To explain the slot opening/closing device 3, reference numeral 4 denotes a frame extending laterally with the slot 5 interposed therebetween.

The frame body 4 is composed of a pair of frame members 6, 6 having a U-shaped cross section, and a square pipe 7 connecting the ends of the frame members 6, 6, and the opening portions of the frame members 6, 6 face each other. Rails 8, 8 are provided so as to correspond to the horizontal surfaces of the frame members 6, 6, and rollers 9, 9, which will be described later, roll on them.

Support arms 10 and 10' for supporting the frame are rotatably provided on the left and right sides of the frame 4, and the support arms 10 and 10' have their base ends attached to the container 1 and their upper ends attached to the frame 4. The right support arm 10 is made longer than the left support arm 10' so that it is inclined when the frame 4 is lifted up. Further, locking members 11, 11 are provided on the container 1 to stop the rotation of the support arm 10' so that when the frame 4 is lifted up, it stops at the position of length a.

12, 12 are springs for rotating the support arms 10, 10', one end of which is connected to the support arms 10, 10';
10', the support arm 1 is attached to support pieces 13, 13 whose other ends are fixed to the container 1.
0,10' is pulled backwards. Reference numeral 14 designates an input port lid that is somewhat larger than the input port 5 provided between the pair of frame members 6, 6, and both sides of the input port lid 14 are bent to form vertical surfaces 15, 15. ing. On the back side of the input port lid 14 corresponding to the input port 5, there is a sealing member 1 that seals the input port lid 14 and the edge of the input port 5 by coming into contact with the edge of the input port 5.
6 is fixed.

Rollers 9, 9 rolling on the rails 8, 8 are pivotally supported on the left and right sides of the vertical surfaces 15, 15 of the input port lid, and the input port cover 14 is slidably supported by frame members 6, 6. It's becoming like that.

Reference numeral 17 indicates a space between the input port lid 14 and the container 1, when the input port 5 is closed by the input port lid 14.
This lashing device consists of a catch 18 that stops the upward movement of the input port cover 14, a stopper 19 that stops the left and right movement of the input port cover 14, and a stopper 20 that stops the downward movement of the input port cover 14. has been done.

By the way, in the present invention, the right support arm 10 is made longer than the left support arm 10, but even if they are the same length, when the frame is moved upward, there is an extra length a. The same is true for opening.

21 is a handle provided on the input opening lid.

The present invention has the above-mentioned structure. Next, the operation will be explained. First, when opening the input port cover 14, when the catch 18 and stopper 19 of the lashing device 17 are released, the support arms 10, 10' and the support piece 13, 13
Due to the force of springs 12, 12 installed between them, the support arms 10, 10' move the locking member 11 to the left.
The frame body 4 and the input port cover 14 move to the upper left position indicated by the dashed-dotted line in FIGS. 5 and 6.

At this time, since the right support arm 10 is longer than the left support arm 10', the frame body 4 is in an inclined state and stops at a position of length a.

Thereafter, by sliding the input port cover 14 along the inclined frame body 4 in the direction of the arrow in FIG. Since it opens extra, even if the input port 5 is large, it can be fully opened.

Next, at the end of the loading work of powder and granules, the loading port 1 is opened.
4, pull the input port cover 14 upward along the frame 4 in the direction opposite to the arrow in FIG.

After that, push down to the solid line position and release the catch 19.
and fasten the stopper 20. It should be noted that the catch 18 and stopper 19 of the lashing device 17 may be of any type as long as they can lash the input port cover 14 above and on the left and right sides.

(g) Effects of the invention As described above, the present invention provides a frame body provided with a rail,
A plurality of support arms are rotatably provided, a spring is provided on the support arms to urge the frame upward, and a lashing device is provided between the input port lid and the container to secure the input port lid. Release the device and
When the frame is moved upward by the spring,
Since the slot cover is moved away from the position of the slot cover when closed and is slid by the length a, the slot can be fully opened even if the slot is large.
