Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rocking device for an incinerator grate.

[0002]

[Prior art]

 Since the grate of small-scale incinerators is usually a fixed type, if incineration is continued, ash and unburned matter will be clogged between the grate, and the air permeability will decrease and the incineration rate will decrease. . Therefore, it is necessary to periodically stir the burned material on the grate with a burning stick or the like to circulate the combustion air, or to drop and remove the ash and the like clogged between the grate. However, the work described above is dangerous because it is necessary to insert a fire stick or the like into the incinerator, and it may not be possible to obtain a sufficient stirring effect.

[0003]

[Problems to be solved by the device]

 The present invention solves such a problem by stirring the burned material on the grate and easily and reliably swinging the fire plate, and the accumulation of ash or the like stuck between the grate An object of the present invention is to provide a rocking device for an incinerator grate capable of reliably dropping and removing an object.

[0004]

[Means for Solving the Problems]

 The present invention, which has been made to solve the above-mentioned problems, has a plurality of rocking grate provided with a fork-shaped receiving groove on the lower surface of the tip end, and the receiving groove is engaged with a horizontal receiving shaft of a furnace body. In addition, the base end is supported by the stage of the furnace body and placed in the furnace, and a rotary shaft equipped with a foot pedal is installed below the stage of the furnace body. The feature is that the tip of the arm extending into the furnace is brought into contact with the lower surface of the rocking grate so that the rocking grate can be lifted. The rocking grate is preferably placed alternately between the fixed grate, and the lifting height of the base end of the rocking grate by the arm is limited above the receiving part of the furnace body. It is preferable to provide a stopper.

[0005]

[Action]

 In order to use the incinerator grate oscillating device of the present invention configured as described above, the rotary shaft is rotated by stepping on the pedal, and the tip of the arm extending from the rotary shaft into the furnace. Lift rocking grate with. Then, the rocking grate is first lifted until its rear end hits the stopper, and when the pedal is further depressed from this state, the tip end of the rocking grate is raised. At this time, the tip of the rocking grate rises while the fork-shaped receiving groove on the lower surface thereof is engaged with the horizontal receiving shaft of the furnace body. When the treadle is released, the rocking grate descends to its original position due to its own weight. By repeating such operations as necessary, it is possible to reliably drop the ash and other deposits on the rocking grate.

[0006]

【Example】

 Next, an embodiment of the present invention will be shown. 1 to 3, reference numeral 1 is a furnace body of an incinerator, and 2 and 3 are receiving portions formed in the lower part of the furnace body 1. A fixed grate 4 and a swinging grate 5 are alternately arranged on these receiving portions 2 and 3. The rocking grate 5 is connected to the upper surface of the part near the tip by a flat plate 6 so that the whole rocking grate 5 can perform a rocking motion, and the end face of the base end is connected to a connecting plate 7. Are linked by.

The rocking grate 5 is provided with a fork-shaped receiving groove 8 on the lower surface of its tip, and this receiving groove 8 is engaged with a horizontal receiving shaft 9 of the furnace body 1 and its base end. Are placed between the fixed grate 4 by placing them on the receiving part 3.

A rotary shaft 10 is provided below the stage 3 of the furnace body 1. A pedal arm 11 is fixed to one end of the rotary shaft 10, and a foot-operated pedal 12 is provided at the tip thereof. The rotary shaft 10 is also provided with a plurality of arms 13, 13 extending into the furnace, and their tips 14 are in contact with the lower surface of the rocking grate 5. The contact position is closer to the base end than the center of the swing grate 5. A stopper 15 is provided above the receiving step 3 of the furnace body 1 to limit the lifting height of the base end of the rocking grate 5 by the arm 13. 16 is a pedal stopper.

In the incinerator grate oscillating device of the present invention having the above-described structure, when the pedal 12 is depressed when ash or the like is accumulated on the grate portion, the rotary shaft 10 rotates and the arm 13, The tip 14 of 13 lifts the part of the swing grate 5 near the base end. As a result, the rocking grate 5 rotates in the clockwise direction in FIG. 2 about the receiving shaft 9 and rises to a position where the base end of the rocking grate 5 hits the stopper 15.

When the pedal 12 is further depressed from this state, the tips 14 of the arms 13 and 13 further push up the swing grate 5, so that the swing grate 5 is centered on the contact portion with the stopper 15. Rotates counterclockwise. At this time, the fork-shaped receiving groove 8 at the tip of the rocking grate 5 rises while being guided by the receiving shaft 9. Then, by releasing the depression of the pedal 12, the rocking grate 5 is lowered to its original position in the reverse order to the above by the weight of the pedal 12.

As described above, the rocking grate 5 alternately arranged with the fixed grate 4 makes a rocking motion in which the base end and the tip end are sequentially moved up and down, and by this operation, the space between the grate is changed. The ash and the like that are clogged in the grate fall due to the shearing action, and at the same time, the burned material on the grate is agitated to improve the air permeability and promote the incineration.

[0012]

[Effect of device]

 As described above, the swing device of the incinerator grate of the present invention swings the swing grate simply by stepping on the pedal outside the furnace to reliably remove the clogging such as ash between the grate. In addition, since the burned material can be sufficiently stirred at the same time, incineration can be promoted. There is also a great advantage that these operations can be performed safely. Moreover, the incinerator grate oscillating device of the present invention is composed of a simple link mechanism and is not of a power type like a large grate oscillating device. Absent.
