Double-air inner suction type feed crusher

Abstract

The invention discloses a double-air inner suction type feed crusher. The double-air inner suction type feed crusher is composed of an engine base, a machine case, a feeding hole, a discharging pipe, a discharging hole, a main shaft, bearing seats, a draught fan, a crushing cabin and a filter screen sheet, wherein the main shaft penetrates through an air blowing cabin, the crushing cabin and the discharging pipe; the two ends of the main shaft are fixed on the engine base by the bearing seats; the part, penetrating through the air blowing cabin, of the main shaft is provided with an air blowing blade group; the part, extending into the crushing cabin, of the main shaft is provided with rotary tables; secondary shafts are arranged among the rotary tables and cutting blades are hung on the secondary shafts; the part, extending into the discharging pipe, of the main shaft is provided with an air suction blade group; the filter screen sheet is mounted on the lower side of the crushing cabin; a conveying groove is formed under the crushing cabin and the discharging pipe; the conveying groove is communicated with the air blowing cabin and the discharging pipe; the design of one shaft and double draught fans is adopted so that an air blower and a discharging air suction machine are arranged in one engine base so that the size of the feed crusher can be reduced; meanwhile, a material conveying path is shortened, the working efficiency is improved and the working time is saved.

Description

technical field [0001] The invention relates to a double-air internal suction feed grinder, in particular to an integrated small double-air internal suction feed grinder, which belongs to the field of agricultural grinders. Background technique [0002] Feed pulverizers are commonly used agricultural machinery in rural households. There are many types of feed pulverizers on the market, but the specific working principles are similar. The main defects are that the structure of feed pulverizers is complex, bulky, and takes up a lot of space. The crushing room and the discharge room use separate fans to work, and the separation of parts is the direct cause of the complex structure and large size of the feed grinder, while the grinder with a single fan often has the problem of low work efficiency. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a double-air internal suction feed grin...
