Description

Technical Field

[0001] The utility model relates to the field of straw feed baling, and more specifically, to a rotary drum air separation type straw feed baling machine. Background Art

[0002] Straw feed baling machines are mainly used for baling and forming corn straws, rice straws, millet straws, peanut straws, and Chinese wildrye, etc., which are mainly used as feed for ruminants such as cattle and sheep, can be used as reserve feed in pastoral areas, and at the same time solve the problems of storage and transportation of forage grass.

[0003] A rotary drum type straw feed baling machine disclosed in Chinese Patent Publication No. CN219165192U can be applied to various baling machine working forms such as traction pressing and site pressing. It can be loaded by machinery such as forklifts and excavators, and is suitable for various large round bales, small round bales made of straws, and bulk materials collected by collectors. All can be processed into feed square bales by this equipment, and it can operate all year round, extending the operation cycle, improving production efficiency, and reducing production costs.

[0004] Since there is no separation structure inside the auger structure of the above-mentioned baling machine, the auger only has the ability to convey materials. Since the auger mainly conveys the straw feed after silk rubbing to the inside of the feeding fan, the impurities on the surface of the straw and the liquid generated during the silk rubbing process will be transferred as the straw moves and move to the inside of the feeding fan. Since the feeding fan cannot convey the large particle impurities on the surface of the straw, it will cause the large particle impurities to accumulate inside the feeding fan, hindering the flow of high-pressure air, resulting in insufficient lift of the high-pressure air generated by the feeding fan on the silk-rubbed straw, and the straw cannot enter the inside of the feeding bin through the high-pressure air generated by the feeding fan. How to improve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a rotary drum air separation type straw feed baling machine, aiming to improve the problem that the feeding structure cannot clean the impurities on the surface of the straw.

Control the operation of the motor 502, so that the motor 502 drives the auger 504 to operate, thereby pushing the shredded straw. When the straw passes through the perforated plate 503, the fine impurities on the surface of the straw and the liquid generated during the shredding process will be discharged through the perforated plate 503. The straw that has completed the preliminary filtration will, under the action of the auger 504, be conveyed to the interior of the sorting bin 601.
