Description

Straw granulator

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to a straw granulator.

Background

The straw is a general term of the stem and leaf parts of mature crops. Generally refers to the remainder of wheat, rice, corn, potatoes, oilseed rape, cotton, sugar cane and other crops after harvesting the seeds. More than half of the products of crop photosynthesis exist in the straws, and the straws are rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, and are a multipurpose renewable biological resource. The straw solidification molding technology adopts agricultural wastes such as straw stalks, wheat stalks, corn stalks and the like as raw materials, and a straw granulator can be used for pressing the crushed stalks to form a solid biomass fuel capable of being directly combusted. The existing granulator has the disadvantages of complex structure, low stability and poor granulation effect.

Detailed Description

Referring to fig. 1-3, the present invention provides a straw pelletizer, comprising; the device comprises a base 1, a barrel 2, a discharge template 3, a rotating shaft 4, a spiral feeding mechanism 5, a material throwing disc 7 and a cutter 8;

the cylinder 2 is arranged on the base 1, and the cylinder 2 is provided with a cylindrical and vertically arranged working cavity; the disc-shaped discharging template 3 is arranged in the barrel 2 and is horizontally placed, and the discharging template 3 is provided with a central hole and a plurality of discharging holes;

the rotating shaft 4 is rotatably arranged on the base 1, the rotating shaft 4 is positioned in the cylinder 2 and is coaxially arranged with the working cavity, and the rotating shaft 4 penetrates through the central hole; spiral feeding mechanism 5, get rid of charging tray 7 from the top down and install in proper order on pivot 4 and all be located barrel 2, spiral feeding mechanism 5 is located discharge mold board 3's top, gets rid of the below that charging tray 7 is located discharge mold board 3, gets rid of and is provided with the knife rest on the charging tray 7, is provided with the cutter 8 that the level was placed on the knife rest.

In this embodiment, still fixed mounting has scraper blade 6 on pivot 4, and scraper blade 6 is located between discharge mold board 5 and spiral feeding mechanism 5, and the lower surface laminating discharge mold board 3's of scraper blade 6 up end, and the one end axial laminating barrel 2 inner wall that pivot 4 was kept away from to scraper blade 6.

In this embodiment, the front side surface of the squeegee 6 is an inclined surface, and the front side surface of the squeegee 6 becomes gradually shorter from top to bottom in the rotation direction of the squeegee 6.

In this embodiment, the upper end of the discharge hole is flared.

In this embodiment, the feed inlet has been seted up to the barrel top, has seted up the discharge gate on the 7 lateral walls of barrel, and the discharge gate is close to the downside of getting rid of charging tray 7 and discharge gate and is not higher than the upper end of getting rid of charging tray 7, and the other containing box that is provided with of discharge gate.

In the specific working process of the straw granulator of the embodiment, the crushed straws are put into the barrel 2 from the feeding hole, and are uniformly conveyed to the upper part of the discharging template 3 through the spiral feeding mechanism 5, meanwhile, the spiral feeding mechanism 5 applies pressure to the crushed straws above the discharging template 3, so that the crushed straws are forcibly extruded into the discharging hole, the upper end of the discharging hole is flared, and the crushed straws entering the discharging hole are gradually increased in the process of moving downwards under the pressure, so that the space is gradually reduced, and the extrusion force on the crushed straws is gradually increased, and the crushed straws are more tightly and firmly adhered; after straw particles formed by crushing straw come out from the lower end of the discharge hole, the straw particles are cut into a proper size by the cutter 8 positioned below the discharge template 3 and fall onto the material throwing disc 7, and the straw particles are thrown out from the discharge hole along with the rotation of the material throwing disc 7 and enter the containing box; the scraper blade 6 that sets up simultaneously rotates on ejection of compact template 3, and during the rotation in-process sent into the discharge opening with the crushing straw that does not get into the discharge opening on ejection of compact template 3, the inclined plane of scraper blade 6 sent into the discharge opening with crushing straw more conveniently, prevented that crushing straw from bonding on ejection of compact template 3.
