In addition, a plurality of fuel storage 240 is fixed to the chain 230, the fuel storage 240 is configured to accommodate a relatively small fuel, that is, a small wood (W) as a kind of tray.

More specifically, the fuel storage 240 is a fixing plate 242 for fixing each inner surface of the inner chain plate 234 constituting the chain 230 and the fixing plate 242 in the vertical direction Wood that is fuel by maintaining an interval while binding the upper storage plate 244a and the lower storage plate 244b and the upper storage plate 244a and the lower storage plate 244b which are arranged and fixed perpendicularly to the plate surface at intervals. It consists of a spacing holding part 246 which forms the space S into which (W) can be inserted.

At this time, the fixing plate 242 is to be fixed over the two to three inner chain plate 234 can have a proper size of the plate surface, and thus the fuel storage 240 to accommodate the wood (W) There is no problem to organize. However, the illustrated example shows an example in which the fixing plate 242 is installed over two inner chain plates 234.

In addition, a bearing support plate BP is fixed to both sides of an inner space in which the chain 230 rotates in a caterpillar form based on FIG. 1, and the bearing support plate BP is in an area that does not prevent rotation of the chain 230. In fixed so as not to move to a separate support, as seen from the side of the wood (W) is a form as shown in Figure 2 (a).

The bearing support plate BP is an upper storage plate 244a so that the upper storage plate 244a constituting the fuel storage unit 240 does not sag downward or bend upward when the upper storage plate 244a is rotated along the chain 230. It is to support while rolling contact with the bearing (B) provided above and below.

On the other hand, the spacer 246 is connected to the upper and lower sides of the upper storage plate 244a and the lower storage plate 244b by constraining each other up and down, and fixed in a hinge form to the center of the spacer 246. It is preferably configured to have rotational fluidity.

This is to allow the upper and lower storage plates 244a and 244b to be rotated along the chain 230 in a caterpillar shape so that they can flow smoothly without being damaged when passing the inflection point where the sprocket is installed.

In addition, the upper storage plate 244a is composed of an upper plate horizontal portion 244a1 and a downwardly bent portion 244a2, and the downwardly bent portion 244a2 is bent to have an acute angle with respect to the upper plate horizontal portion 244a1. It has an inverted a-shape with the letter 'a' upside down.

In addition, the lower storage plate 244b is composed of a lower plate horizontal portion 244b1 and an upward bent portion 244b2, but the upwardly bent portion 244b2 has a vertically bent structure and has an overall 'b' shape. .

Thus, the space between the upper storage plate 244a and the lower storage plate 244b is maintained by the gap retaining hole 246 so that the upward bent portion 244b2 is disposed at intervals inside the downward bent portion 244a2. Are matched to each other in a state.

In addition, the protrusion 244a3 protrudes on the lower end surface close to the downward bent portion 244a2 of the upper storage plate 244a and is provided to interfere with the upward bending portion 244b2 so that the lower storage plate receives the load ( When the upper portion 244b2 sags downward, the upwardly bent portion 244b2 catches the protrusion 244a3 and performs a kind of stopper function.

This is to minimize the phenomenon that occurs because the upper storage plate 244a and the lower storage plate 244b is not rigidly fixed by the spacer 246, but is fixed to have a fluidity in a hinged manner. .

 In addition, one end of the upper storage plate 244a, that is, the end where the downward bent portion 244a2 is formed, is bound to the fixing plate 242 through the connector 248, so that the wood S in the space S The fuel storage compartment 240 may be drooped downward by the load at the time of charging.

In this case, the connector 248 is preferably hinged only to the upper one of the upper and lower inner chain plate 234 to secure the fluidity of the fixing plate 242.

In particular, the phenomenon is more prominent at the inflection point where the rotation direction is changed to the opposite direction through the sprocket 240, the smooth rotational flow is possible while preventing the sag of the fuel storage 240 is sag. Bearings B may be installed on the outer surface of the downward bent portion 244a2 and the upper surface of the upper storage plate 244a, respectively, and the function thereof is as described above.

In this case, the bearing B may be a roller.

Meanwhile, as illustrated in FIGS. 1 and 3, the fuel input unit 300 includes an input guide 310 arranged toward the furnace door 110 installed at the inlet of the furnace 100.

The input guide 310 is disposed below the driven sprocket 220 and is arranged in a straight line toward the furnace door 110.

In addition, a push rod 320 is provided inside the input guide 310, and the push rod 320 is fixed to the push chain 330, and the push chain 330 is provided at both ends of the bottom surface of the input guide 310. It is configured to be rotated by receiving power from the push rod driving motor 340 in a state in the form of an endless track wound on two rotating sprockets (drawing numbers omitted). Therefore, the bottom surface of the injection guide 310 on the path in which the push rod 320 and the push chain 330 moves is opened in the form of a through hole (H) so that the push rod 320 can be fixed to the push rod chain 330. Should be.

In addition, the push rod driving motor 340 is preferably the same as the step motor capable of forward and reverse rotation, when the wood (W) input the push rod 320 to the opposite end of the furnace door 110 of the injection guide 310 as much as possible When the movement of the wood (W) is completed, the push rod driving motor 340 is driven and the wood (W) is pushed into the push rod 320 is charged into the furnace 100 through the furnace door 110.

At this time, as shown in Figure 1 and 3 (a), the fuel detection sensor 350 may be further installed on the bottom surface of the end of the furnace door 110 side of the input guide 310, the fuel detection sensor ( When the furnace door 110 is rotated and opened by the furnace door opening and closing means, it detects instantaneously whether the fuel state inside the furnace 100 is present, that is, whether there is fuel, and controls the detection result. In the case of no fuel, the control unit completely opens the furnace door 110 and, if there is fuel, inputs fuel, that is, wood (W) through the straw 320. It can be held and held in the input standby state, thereby enabling more efficient fuel input operation.

In this case, the furnace door opening and closing means is a fixed plate (P) which is installed across the upper end of the input guide 310 in the width direction, and a drum (not shown) fixed and rotated on the fixed plate (P) The opening and closing motor (M) provided, and may be configured to include a wire rod (R), one end of which is wound around the drum of the opening and closing motor (M) connected to the lower end of the furnace door (110).

Accordingly, since the wire rod R is pulled when the open / close motor M is rotated, the furnace door 110 may be rotated in the pulling direction or closed.

In addition, reference numeral 360 is a means for maintaining the tension of the chain.

In addition, in the structure of the present invention, when the wood (W) is pushed into the furnace 100 by the pusher 320, most of the wood is stacked at the inlet portion of the furnace 100, and thus the input efficiency may be reduced.

Therefore, in order to further improve the charging efficiency, an additional plate 370 such as (b) of FIG. 3 may be further installed, and the additional plate 370 is an end bottom surface of the furnace door 110 side of the feeding guide 310. It is installed to be slidable, the push rod 320 is moved to contact the lower end of the push rod 320 when the wood (W) while the furnace door 110 is designed to operate only slightly protruded toward the furnace 100 in the open state. do.

Therefore, the wood (W) can be prevented from being concentrated in the inlet portion because the additional plate 370 as far as the protruded fall into the furnace 100.

At this time, the additional plate 370 is formed on both sides of the side avoiding the path that the chain 330 is moved so as not to interfere with the chain 330, that is, the guide groove 312 is formed on both sides of the bottom surface of the input guide 310, The guide protrusions 372 seated in the guide grooves 312 and guided to slide are formed on the bottom surface of the additional plate 370 so as to be assembled smoothly.

In addition, the guide protrusion 372 of the additional plate 370 and the bottom surface of the input guide 310 by connecting the spring (SP) when the additional plate 370 is pushed in the interference state with the push rod 320 (spring) If the SP is increased and the pusher 320 returns to the home position, it is better to configure the spring SP, which has been extended, to move the additional plate 370 back to the initial position while returning to the original position.

According to the present invention, when the wood (W) is charged to the fuel holder 240 fixed to the rotating chain 230, the wood (W) is rotated on the chain 230 while the driven sprocket 220 side down As a result, the wood W escapes from the fuel storage compartment 240 by its own weight and falls downward.

Subsequently, the fallen wood (W) falls into the input guide (310), and when the wood (W) falls, pushes the wood (W) while advancing the wheat (320) into the furnace (100).

Since such a process is automatically performed repeatedly, fuel charging into the furnace 100 using wood (W) as fuel can be easily and conveniently performed.

As another example, as shown in FIG. 4, the push rod may be changed into a carriage 320 ′, and a means for sliding the carriage 320 ′ may be installed inside the injection guide 310.

In this case, the transport vehicle 320 'is in the form of transporting and supplying the wood (W) burned.

As such, the fuel injector according to the present invention can easily and conveniently supply the fuel wood (W) to the furnace 100 side, thereby improving convenience in use and improving management efficiency.
