The fire grate is a rolling fire grate with a plurality of rolling shafts arranged side by side, the rolling shafts are provided with hobbing teeth, and the rolling shafts are connected through chains.

The utility model has the advantages that: 1. the straw carbon burning device is matched with a corn harvester for use, crushed straws of the combine harvester are picked up and directly burned, the generated straw carbon and plant ash are directly returned to the field after burning, soil hardening can be effectively treated, the plant ash is directly returned to the field as organic potassium fertilizer, and soil fertility can be increased. 2. Reasonable structure, high mechanization degree, matching with agricultural machinery and continuous production.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-4, the part names are as follows: the straw incinerator comprises a tractor 1, a straw pick-up mechanism 2, a flat car 3, an incinerator 4, a hobbing type rotating roller 5, spiral conveying hobbing 6, a chute 7, a shifting fork 8, a feeding port 9, a pushing plug 10, a combustion chamber 11, an arch 12, a grate 13, a feeding port 9, an ash discharge port 14, hobbing 15, a chain 16, a waste receiving groove 17, a chimney 18, a rolling shaft 19, an auxiliary transmission gear 20, a transmission gear 21, a gear box 22 and a driving shaft 23.

Referring to fig. 1, 3 and 4, the movable waste straw incinerator is composed of a tractor 1, a straw pick-up mechanism 2, a flat car 3 and a straw incinerator 4 loaded on the flat car 3 which are connected in sequence; the straw pick-up mechanism 2 comprises a rotary hobbing type rotating roller 5 (see figure 3) for picking up straws, a spiral conveying hobbing 6 for reeling and feeding the straws is arranged behind the hobbing type rotating roller 5, a straw chute 7 is arranged behind the spiral conveying hobbing 6, a reciprocating raising shifting fork 8 is arranged above the chute 7, the upper end of the chute 7 is connected with a hearth feeding port 9, and the rear end of the feeding port 9 is provided with a reciprocating push plug 10; the power mechanism of the tractor 1 is connected with the power mechanism of the straw picking mechanism 2 (see figure 4).

The straw incinerator 4 comprises a furnace body combustion chamber 11, a furnace arch 12 and a fire grate 13, wherein a feeding port 9 and an ash discharging port 14 are formed in the furnace body combustion chamber.

Referring to fig. 2 and 4, the grate 13 is a rolling grate with a plurality of rolling shafts 19 arranged side by side, the rolling shafts 19 are provided with hobbing teeth 15, and the rolling shafts 19 are connected through a chain 16.

Ground straw is picked up through hobbing formula commentaries on classics roller 5, send to chute 7 through auger delivery hobbing 6 (being helical blade along width direction and arranging), send the straw to pay-off mouth 9 (feeding chamber) by shift fork 8 (having a row of sharp rod teeth of spaced along width direction) again, by push plug 10 with straw propelling movement to combustion chamber 11 in (the furnace body), the straw is through grate 13 rotation drive, the while is burning in the stove, the straw burns under the disturbance condition of grate 13 and walks, drop to ash discharge port 14 and connect in the waste chute 17. The grate 13 rotates in a chain 16 transmission mode, and the picking process adopts a gear transmission mode. The combusted flue gas is discharged to the air through the chimney 18.

The working principle is as follows: the power supply of traction power and straw pickup mechanism 2 is provided to traction tractor 1, and hobbing formula change roller 5 is collected the straw bulk cargo that corn harvester scattered ground buried, sends the straw to burning furnace 4 in through shift fork 8, chute 7, pay-off mouth 9, plug 10, and the straw fully burns through the straw combustor in burning furnace 4, and the ash after the burning is collected to ash discharge port 14, collects the packing and reprocesses.

Picking up: through actual field investigation, after the corn harvester finishes working, the straws are crushed and scattered in a farmland, and the straws with different lengths cover furrows and ridge platforms. The existing pickup bundling machine needs the raker to concentrate scattered straws before working, and then two processes of picking and bundling are carried out, the main reason is that the straws scattered in furrows are not picked up in place, and large-area furrows can be accumulated and stored with straws under the condition of not using the raker in advance. The reason for the improper straw pick-up in the furrow is mainly that the hobbing rigidity is large and the hobbing length is consistent, and the furrow and the ridge are not distinguished. The sizes of furrows and ridges of a corn farmland in the Changchun region are basically 300-350 mm through actual measurement, the depth of the furrows is about 150mm, the problem of insufficient picking is solved, the picking is optimized, the rigidity of the hobbing gears is reduced, meanwhile, the length of the hobbing gears is combined with the size of the furrows and ridges of the Changchun region to change the hobbing gears into a non-equal length form, the picking effect is improved, the procedure of a raking machine is saved, and the work content is reduced. And (3) combustion: the incinerator 4 adopts a disturbance combustion mode and a multipoint air supply technology, so that the straws are sufficiently and rapidly combusted, and clean emission is achieved. The disturbance combustion mode is matched with the pick-up efficiency, 800-1000 kg of straws can be treated in each hour, and the disturbance combustion mode can be increased or reduced according to the treatment requirement. The combustion can be continued by one-time ignition.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
