A high-efficiency negative pressure grain feeding machine

Abstract

The invention discloses an efficient negative pressure cereal loading machine. The efficient negative pressure cereal loading machine comprises a hopper. The feed port of the hopper is connected with a loading pipe, and the other end of the loading pipe is connected to the feed port in the upper end of a transition bin. A vertical storage pipe is arranged at the discharge port in the bottom of the transition bin, an air suction pipe is arranged at the air outlet in one side of the transition bin, and the other end of the air suction pipe is connected with a fan. An exhaust pipe is vertically connected to the air outlet of the fan, a separator is connected to the bottom of the exhaust pipe, a recovery pipe is connected with the separator, and the other end of the recovery pipe is connected in the hopper. According to the efficient negative pressure cereal loading machine, the transition bin is higher than the hopper, after the fan is started, cereals flow into the transition bin from the hopper through the loading pipe due to the negative pressure of the transition bin, and due to the fact that the unit weight and the kinetic energy of impurities are smaller than those of the cereals, the impurities can be separated from the cereals by reasonably controlling the rotation speed of the fan. According to the efficient negative pressure cereal loading machine, damage to the surfaces of the cereals is small, the noise is small, the impurities can be separated through the separator, and the cleaning time for the cereals is saved.

Description

technical field [0001] The invention relates to a high-efficiency negative pressure grain feeder, which belongs to the technical field of grain packaging, packaging and processing equipment. Background technique [0002] With the increase of the country's investment in agriculture, grain production is increasing year by year, and crop processing is gradually realizing automation, and the use of feeding machines is also increasing year by year. At present, the bucket feeding, belt feeding, and screw feeding in the grain feeding methods have the following defects: large volume, large floor area, heavy, loud noise, easy to damage the surface of the grain, and the inability to remove leaves in the grain, Bran shells and shriveled grains, while vacuum feeding is often intermittent feeding during the feeding process, and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is: to provide a high-efficiency negative pressure grain feeding...
