Pneumatic feeding device

Abstract

The invention relates to the field of discharge hoppers, in particular to a pneumatic feeding device. The pneumatic feeding device comprises a feeding box body, wherein a hinge shaft is arranged in the feeding box body; an observing barrel is arranged at the upper end of the feeding box body; a rotary hopper is arranged at a position parallel to the observing barrel, is hinged to the feeding box body through the hinge shaft, is positioned in the feeding box body and is conical; a feeding opening and a discharging opening are formed in the rotary hopper; the aperture of the feeding opening is greater than that of the discharging opening; a cylinder is arranged on the left side of the bottom of the feeding box body and comprises a piston and a piston rod; the piston rod is fixedly connected with the rotary hopper; a supporting mechanism is arranged on the right side of the bottom of the feeding box body and comprises a baffle and a supporting shaft; one end of the supporting shaft is fixedly connected with the bottom of the feeding box body; the other end of the supporting shaft is fixedly connected with the baffle; a through hole is formed in the right side of the feeding box body; and a limiting bolt penetrates through the through hole and is in threaded connection with the feeding box body. According to the scheme, fruits can be quantitatively conveyed, the conveying amount of the fruits can be adjusted flexibly, and meanwhile, the pneumatic feeding device is long in service life.

Description

technical field [0001] The invention relates to the field of unloading hoppers, in particular to a pneumatic feeding device. Background technique [0002] Fruit processing requires a variety of machines, and these machines all need a feeding device to add fruit. The most commonly used feeding device in the prior art is a spring feeding device. The spring feeding device includes a feeding tube. There is a baffle, one end of the baffle is movably connected to the inner side of the feeding tube, the other end of the baffle is fixedly connected to one end of the compression spring, and the other end of the compression spring is fixedly connected to the inner side of the feeding tube, when a certain amount of fruit enters the feeding tube, press down the baffle The fruit flows in behind the plate; the spring of this spring feeding device is easily damaged, so the service life is not long. At the same time, if it is necessary to make different amounts of fruit flow in, it needs to...
