Abstract

The invention relates to agricultural machinery, in particular, to machines of technological lines of feed preparation shops, and is intended for separating foreign solid objects from fodder. The purpose of the invention is to increase the efficiency of the separation of foreign solid objects. Conveyor belt contains perforated tape with spikes 2, envelope loading drum 3, end discharge drum 4 and additional drum 5. Drums 4 and 5 have a perforated surface and are equipped with thin-walled chambers installed inside them, which are connected by nozzles in the drum 4 to a source of compressed air, and in the drum 5 with a discharge source under the drum 4 there is a receiving tray 11 for the material and a tray 12 for foreign solid objects, and in front of the drum 5 there is a tray 13. Inclined branch of the belt 1 between the drums and 5 and 4 are enclosed in the chute 14. Tape 1 delivers the feed mass to the drum 5, where the material is attracted to the tape by vacuum created in the drum cavity, and solid inclusions fall into the tray 13. In the section of the drum 4 the material is blown off into the receiving tray 11 for material, small stones are dumped in tray 12. 2 Il.

The invention relates to agricultural machinery, in particular to machines of technological lines of feed preparation shops, is intended to separate foreign solid objects from forage and is an improvement of the conveyor according to the author. St. No. 695904.

The purpose of the invention is to increase the efficiency of separating foreign solid iipe.a-metov from feed.

FIG. 1 shows a belt conveyor; in fig. 2 - discharge drum, longitudinal section.

Belt conveyor contains perforated belt 1 with tires 2, enveloping double overload drum 3, end discharge () drum 4 and additional discharge drum 5. Drums 4 and 5 have perforated working surface and are equipped with thin-walled chambers 6, which are connected by nozzles 7 in the drum 4 with a source of compressed air and in the drum 5 with a vacuum source mounted on the frame of the belt conveyor. In the walls of the chambers (i there are windows 8, which are located in front of the arc of the circumference of the drums 4 and 5 of the leptum I. Between the walls of the drums 4, 5 and chambers 6 there are seals 9 and 10. One of the drums is driven (not shown) Under the drum 4 place the receiving .iioTOK 1 I d.ch material and tray 12 D.1I extraneous twisting, and in front of the drum 5. ytok 13. Inclined branch of the tape 1 between the 5 bass abanami 5 and 4 is enclosed 5 chute 14.

The belt conveyor works as follows.

Feed mass is fed to belt 1, which, 11remecting in the direction indicated by the arrow, picks up the spikes 2

grass and feeds to the additional discharge drum 5. The passage is a portion of the drum 5, located in front of the window 8, the material falls under the action of a vacuum, which attracts the material to the belt 1. At the same time, foreign inclusions (stones or metal) fall into the tray due to greater density 13. Then the material, cleared of extraneous inclusions of large weight, is fed by the tape 1 to the end discharge drum 4. On the inclined section of the conveyor, between the drums 5 and 4, the conveyor belt 1 does not serve as a supporting surface for small stones, vshihs in the grass, with the result that they fall into the chute 14 with a small part of grass. The passage of the drum 4, located in front of the window 8, the material enters the stream of compressed air and is demolished from thorns 2 to the receiving tray 11 for the material, located at some distance from the drum 4. There is also grass that falls out of the groove 14. Small stones from chute 14, as well as those stuck in the grass, are dumped in tray 12, which ensures high efficiency in separating foreign solid impurities from the forage.
