Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a vertical-core oil combustor in which the rotational movement of the vertical axis of the core is caused by a crank action to linearly move the core up and down. .

(b) Conventional technology and problems Instead of a pinion system in which a pinion installed on the vertical axis of the core easily engages with the core side and moves the core up and down while rotating the core, a crank mechanism is used to move the core in a straight line. An oil combustor that moves up and down has already been proposed.

This conventional technique will be explained based on FIGS. 1 to 3. An arm receiving plate 3 is attached to a core support fitting 2 holding a core 1 by spot welding 4 at both ends.
A locking hole 8 is bored in the arm receiving plate 3 to lock with a locking protrusion 7 of an arm plate 6 attached to the tip of the core vertical shaft 5. Also, the tip 5' of the core vertical shaft 5 is connected to the arm receiving plate 3.
The core support fitting 2 is inserted into the vertical slit 9 to guide the linear movement of the core support fitting 2.

Then, by rotating the core vertical shaft 5, the arm plate 6 is rotated, and the core support fitting 2 is moved linearly by the engagement between the locking protrusion 7 of the arm plate 6 and the locking hole 8 of the arm receiving plate 3. The core body 1 is moved linearly between the combustion position and the extinguishing position.

In such prior art, the position where the locking protrusion 7 of the arm plate 6 locks on the arm receiving plate 3, that is, the locking hole 8
Since the position of the core body 1 cannot be adjusted in the vertical direction, it is not possible to adjust the combustion position of the core body 1 to the optimum combustion position. In other words, when the core 1 is attached to the core support fitting 2, if the attachment position is shifted, the height of the core may be too low or the height may be reversed even if the core vertical axis 5 is used to raise the core to the combustion position. It may appear too much. If it is too protruding, you may be able to slightly reverse the lead vertical axis 5, but if the height is too low, it will not be possible to raise it any further even if you operate the lead vertical axis, and in that case, the oil combustion It was necessary to disassemble the device and reinstall the core body 1 and core support fitting 2.

(c) Object of the present invention When the problems listed in the section of problems with the prior art occur, the trouble of reattaching the core body to the core support metal fitting is eliminated, and the fixing mechanism is provided on the arm receiving plate side. The purpose is to facilitate maintenance and inspection so that the position of the hole can be easily adjusted in the vertical direction.

(d) Structure of the present invention In the present invention, an arm receiving plate is fixed to a core support fitting to which a core is attached, an arm plate for moving the core up and down is attached to the core vertical axis, and the arm plate is engaged with a locking protrusion of the arm plate. The present invention is characterized in that an adjustment plate having a locking hole is attached to the arm receiving plate so as to be adjustable in the vertical direction.

(e) Effects of the Invention In the present invention, since the adjustment plate is vertically adjustable with respect to the arm receiving plate, the position where the locking protrusion of the arm plate locks (i.e., the locking hole) can be adjusted, and the Even if the position of the body is inappropriate with respect to the core support fitting, the core body can be easily operated without removing the core from the metal fitting.

(f) Embodiment of the Invention An embodiment of the present invention will be described based on FIGS. 4 to 6. Reference numeral 10 denotes a fuel tank having a core guide inner cylinder 11 erected in the center, and a gasket 12 on the upper surface. A core guide outer cylinder 13 is attached to the inner cylinder 11 with a gap therebetween. 14 is a core guide inner and outer cylinder 11,1
3, the lower end is immersed in the fuel 15, the core body is moved up and down linearly by a wick up and down mechanism described later, the upper end protrudes from the fire pan part 16, and the combustion cylinder is placed on the fire pan part. (not shown). 17 is a cylindrical core support fitting fixed to the outer periphery of the core body 14 with claws, 18 is an arm receiving plate whose both ends are fixed to the core support fitting 17 by spot welding 19, and a single metal plate is pressed. A vertical guide slit 20 is vertically provided in the left side portion when viewed from the front, which is formed by processing. Further, a cut-and-raised tongue piece 21 with a mounting hole 21' is formed at the upper right end, and a square opening 22 is provided below this tongue piece 21.
is drilled. Reference numeral 23 denotes an adjustment plate in which a horizontally long engagement hole 24 is bored, and the screw hole 2 is located opposite to the tongue 21.
5' at the upper end, and a sliding piece 26 at the lower end that is inserted into the square opening 22 and has a length that does not come out even when the adjustment plate 23 moves up and down within the permissible range. The adjustment plate 23 can be adjusted by screwing the adjustment screw 27 attached to the attachment hole 21' of the tongue piece 21 into the screw hole 25' of the ear piece 25 so that it can move forward and backward. It is designed to be able to move up and down.

Reference numeral 28 denotes a coil spring storage section installed vertically on both sides of the arm receiving plate 18, in which a pair of core lowering coil springs 29 are stored together with a guide rod 30, and the force is stored when the core is raised by the core up-and-down mechanism described later. When the combustor vibrates, the accumulated force is released by the operation of the seismic sensor, and this accumulated force causes the core body 14 to drop rapidly.A well-known mechanism is used to maintain and release the accumulated force. Reference numeral 31 denotes a core vertical shaft serving as a core vertical mechanism, which is rotatably supported by a shaft support plate 32 fixed to the fuel tank 10, and is rotated by rotation of an operating lever (not shown) or vertical operation. The movement is prevented by a regulating body 33 in the front-rear direction.

The tip of this lead vertical shaft 31 is formed into a small diameter portion 31', which is inserted into the guide slit 20 of the arm receiving plate 18, so that the lead support fitting 17 can be moved up and down smoothly. Reference numeral 34 denotes an arm plate made of oil-resistant synthetic resin such as Diuracon, which is inserted through and attached to the non-circular portion at the tip of the core vertical shaft 31, and is attached to the engagement hole 24 of the adjustment plate 23.
A locking protrusion 35 that is locked to is integrally molded.

Therefore, when the core vertical shaft 31 is rotated counterclockwise by about 60 degrees (1/6 rotation) using the operating lever, the arm plate 34 rotates counterclockwise about the core vertical shaft 31. Since the locking protrusion 35 of the arm plate 34 is engaged with the locking hole 24 of the adjustment plate 23, the arm receiving plate 18 is moved upward by the rotational movement of the arm plate 34, and as a result, the core body 14 is also moved upward. At this time, the locking protrusion 35 is connected to the locking hole 2.
4 from the right end to the left end and the core vertical axis 31
Since the small diameter portion 31' of the arm receiving plate 18 is inserted into the guide slit 20 of the arm receiving plate 18, the arm receiving plate 18 is moved upward linearly.

In this way, the core body 14 can be moved up and down linearly. If the wick 14 rises to the combustion position and the combustion condition becomes unstable due to an inappropriate position, remove the wick guide outer cylinder 13 from the tank 10 and tighten the adjustment screw 2.
7 with a jig to move the adjustment plate 23 up and down,
Adjust the locking hole 24 to the optimum position.

In this way, the position of the core can be optimally adjusted using a simple adjustment means.
