Furthermore, both ends of the swinging grate shaft are provided with swinging driving mechanisms.

Further, the swing driving mechanism comprises a swing connecting plate, a left swing oil cylinder and a right swing oil cylinder, the swing connecting plate is fixedly connected with the swing grate shaft, the left swing oil cylinder and the right swing oil cylinder are respectively arranged on the left side and the right side of the swing connecting plate, and a piston rod of the left swing oil cylinder and a piston rod of the right swing oil cylinder are respectively hinged with the left side and the right side of the swing connecting plate.

Furthermore, the swinging connecting plate is sleeved with the swinging grate shaft, and circumferential positioning is realized through a key structure.

Furthermore, the swing grate comprises an arc grate bottom plate and two grate side plates arranged at two ends of the arc grate bottom plate, and the grate side plates are fixedly connected with the swing grate shaft.

Further, the bottom of the incinerator is a cambered surface.

Furthermore, a fire grate purline is arranged on the bottom plate of the arc-shaped fire grate.

The invention has the beneficial effects that:

1. the garbage rolls left and right under the action of the swinging grate, so that the garbage gap is increased, the oxygen is favorably ensured to enter, the combustion is more sufficient, and the combustion temperature is higher;

2. the garbage rolls left and right under the action of the swinging grate, so that the phenomenon of hardening caused by long-term combustion of the garbage at one place is avoided;

3. the furnace type is simple in structure, easy to implement, high in operability, low in manufacturing cost compared with a large-scale traditional mechanical grate and good in economical efficiency.

Detailed Description

The invention is explained in more detail below with reference to the figures and examples. The features and advantages of the present invention will become more apparent from the description. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments.

As shown in fig. 1-7, the small vertical garbage incinerator with the rocking grate of the present embodiment includes an incinerator, the top and bottom of the incinerator are respectively provided with a smoke outlet 9 and a discharge outlet 7, and a feed inlet 1 is disposed on the side wall of the incinerator near the top.

The incinerator is internally provided with a swinging grate 2, a swinging grate shaft 10 is arranged above the swinging grate in a crossing manner, as shown in figure 3, the swinging grate comprises an arc grate bottom plate 22 and two grate side plates 21 arranged at two ends of the arc grate bottom plate, and the grate side plates 21 are fixedly connected with the swinging grate shaft 10. Two ends of the swinging grate shaft 10 are respectively and rotatably matched with the corresponding side wall of the incinerator, at least one end of the swinging grate shaft 10 is provided with a swinging driving mechanism for driving the swinging grate shaft to swing back and forth, and preferably, as shown in fig. 2, two ends of the swinging grate shaft 10 are both provided with swinging driving mechanisms.

As shown in fig. 1-2, the swing driving mechanism includes a swing link plate 4, a left swing cylinder 5 and a right swing cylinder 6, the swing link plate 4 is sleeved with a swing grate shaft 10, and circumferential positioning is realized through a key structure 8, the left swing cylinder 5 and the right swing cylinder 6 are respectively disposed at left and right sides of the swing link plate, and a piston rod of the left swing cylinder 5 and a piston rod of the right swing cylinder 6 are respectively hinged with left and right sides of the swing link plate.
