The further preferred technical scheme of the utility model is also to be provided with handwheel, and handwheel is connected with power transmission shaft.
The utility model adopts the Bilayer oven door structure, and when outer fire door, when upwards walking, interior fire door are walked downwards, the contact on spring attachment starts to contact with the wedge on interior fire door.Wedge is provided with slope, and along with walking on of outer fire door and interior fire door, the gradient of the wedge of contact contact is more and more higher, makes the spring be connected with contact little by little shorten, thereby interior fire door and outer fire door are compressed.The utility model is provided with two-layer fire door and mutually compresses by spring attachment, and sealing property is splendid, and the situation that burner hearth can not produce thermal loss and outwards smolder has further improved the operating efficiency of Cremation Machine.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is rearview of the present utility model.
Symbol description in figure:
1. motor; 2. reductor; 3. power transmission shaft; 4. sprocket wheel; 5. chain; 6. interior fire door; 7. outer fire door; 8. wedge; 9. spring attachment; 10. spring; 11. contact.
The specific embodiment
Describe with reference to the accompanying drawings the specific embodiment of the present utility model in detail.
As shown in Figure 1, Figure 2 and Figure 3, the utility model mainly is provided with motor 1, reductor 2, power transmission shaft 3, sprocket wheel 4, chain 5, interior fire door 6, outer fire door 7, wedge 8 and spring attachment 9.
Motor 1 is connected with reductor 2, and reductor 2 is connected with power transmission shaft 3.When motor 1 work, drive reductor 2 work, further make power transmission shaft 3 rotate.Because the speed of opening and closing fire door does not need too soon, so be provided with reductor 2 between motor 1 and power transmission shaft 3, with this, realize the opening and closing that fire door is stable.When the rotating speed of motor 1 is very little, also reductor 2 can be set.
Be fixed with two sprocket wheels 4 on power transmission shaft 3, each sprocket wheel 4 all is arranged with a chain 5, and chain 5, then stretches out from the opposite side of sprocket wheel 4 around sprocket wheel 4 from a gusset of sprocket wheel 4, and the both sides of sprocket wheel 4 are equipped with chain 5.The chain 5 of the same side on two sprocket wheels 4 is connected with interior fire door 6, and the chain 5 of opposite side is connected with outer fire door 7.Sprocket wheel 4 also can arrange more than two.
Plane relative with outer fire door 7 on interior fire door 6 is provided with four wedges 8, and plane relative with interior fire door 6 on outer fire door 7 is provided with four groups of spring attachments 9.Spring attachment 9 is provided with spring 10, on spring 10, with the close end of wedge 8, is provided with contact 11.When fire door is closed, the contact 11 on spring attachment 9 and wedge 8 close contacts on interior fire door 6, make the spring 10 of spring attachment 9 compressed, thereby interior fire door 6 and outer fire door 7 are compressed.Spring attachment 9 can be also other form, only needs to guarantee that it can compress fire door to get final product.
Because interior fire door 6 contacts with the Cremation Machine burner hearth, so interior fire door 6 is preferably the high temperature aluminosilicate material.
Below the course of work of the present utility model is illustrated:
When motor 1 work, drive reductor 2 and rotate, further drive power transmission shaft 3 rotations that are connected with reductor 2.Because sprocket wheel 4 is fixedly connected with power transmission shaft 3, so the rotation of power transmission shaft 3 can be with movable sprocket 4 to rotate together.Be set in respectively again the both sides of two sprocket wheels 4 because of two chains 5, the chain 5 of the same side on two sprocket wheels 4 is connected with interior fire door 6, the chain 5 of opposite side is connected with outer fire door 7, so just make two chains 5 be pressed on two sprocket wheels 4, so when two sprocket wheels 4 rotate, the upwards walking of outer fire door 7, interior fire door 6 is walked downwards, and the spring attachment 9 on outer fire door 7 starts to contact with the wedge 8 on interior fire door 6.Wedge 8 is provided with a slope, along with walking on of outer fire door 7 and interior fire door 6, the gradient of the wedge 8 of spring attachment 9 contacts is more and more higher, and spring attachment 9 little by little shortens, thereby interior fire door 6 and outer fire door 7 are compressed, make whole fire door in closed condition.
When motor 1 reversion, outer fire door 7 is walked downwards, the upwards walking of interior fire door 6, and the gradient of the wedge 8 of spring attachment 9 contacts is more and more lower, and compressed spring attachment 9 little by little extends, thereby makes whole fire door in open mode.
The utility model can also be connected with handwheel at the other end of power transmission shaft 3, when the situation of outage occurring, just can drive power transmission shaft 3 rotations by rotating handwheel, thereby control the opening and closing of fire door.
Only as described above; it is only specific embodiment of the utility model; when not limiting the scope that the utility model is implemented with this; therefore the displacement of its equivalent assemblies; or the equivalent variations of doing according to the utility model scope of patent protection and modification, all should still belong to the category that the utility model claims are contained.
