High-speed straw bale breaking feeding machine

Abstract

The invention discloses a high-speed straw bale breaking feeding machine, which comprises a shell, wherein the front end of the shell is provided with a feed port; the bottom end of the shell is provided with a discharge port; bale breaking feeding rolls are symmetrically arranged on the left side and the right side in the shell, and each bale breaking feeding roll consists of a roll shaft, a hob and a cleaning knife; the hob consists of a row of rotary cutting bale breaking sheets which are fixed on the roll shaft at intervals; each rotary cutting bale breaking sheet is provided with a plurality of convex knife valves; the cleaning knife is flat-plate-shaped, is obliquely arranged between the roll shaft and the side wall of the shell, and is provided with a row of knife grooves; the rotary cutting bale breaking sheets are embedded in the knife grooves respectively; and the roll shaft is connected with a driving device. The rotary cutting bale breaking sheets crush straw bales and continuously and quickly break up the straw bales to realize uniform feeding of the straws downwards. The knife grooves on the cleaning knife cut, pull and tear apart nylon ropes hung on the rotary cutting bale breaking sheets, so the problem that the nylon ropes and long straws are wound together to form blockage and delay production is solved, potential accidents are eliminated, and large-delivery-capacity, high-efficiency, safe and reliable feeding is realized.

Description

Technical field [0001] The invention relates to a feeder in front of a furnace in a biomass power plant, in particular to a straw bale crushing feeder. Background technique [0002] Biomass power plant uses crop straw as fuel, heats the boiler, produces steam, and drives the generator to generate electricity. In order to facilitate transportation and stacking, various crop straws must be compressed into rectangular straw bales with consistent specifications and then stacked In the power plant warehouse, the conveyor is transported to the crusher in the furnace front feeding system of the power plant for unpacking and crushing. The crushers currently used are all vertical spiral crushers produced by the introduction of Dutch technology. The straw bales in our country are bundled with nylon ropes. When feeding, the nylon ropes are easily wound on the rollers of the vertical spiral crusher. The production unit has to send someone to cut the rope with a sickle. Long straws such as s...

AI Technical Summary

Problems solved by technology

Long straws such as rice straw and wheat straw are easily entangled when they pass through the vertical screw crusher, and the long straws in agglomerates are squeezed into the equipment, resulting in an accident of shutdown due to excessive load and blockage, which seriously affects the safe production of biomass power plants

[0003] Biomass power plants have a large demand for raw materials. Cutting ropes manually with a sickle has low efficiency and does not conform to standardized operations. The transportation volume of straw is small, delaying production, and it is unsafe and has potential accidents. Therefore, it is urgent to develop a large-scale transportation Feeding volume, high efficiency, safe and reliable straw unpacking feeder
