Abstract

The invention discloses an energy-saving and environment-friendly vibrating conveyer which comprises a groove body and a base. The groove body is movably connected with the base through a vibration attenuation supporting spring and a plate guide supporting spring. Motors are installed below the middle section of the groove body. The motors are in key connection with large belt wheels, and the large belt wheels are installed at the two ends of a main shaft. Screw rods are symmetrically arranged at the left portion and the right portion of the lower portion of the groove body and are connected with bearing housings at the two ends of the main shaft, compression is conducted by a compressing cover to form elastic connection through a spring support, and the spring support is fixedly connected with the groove body. According to the technical scheme, the plate guide supporting spring and a power spring can generate stronger bounce under the power effect, and a transmission gear can more efficiently provide power for the conveyer through the bounce, so that the requirement for prime power in the working process is reduced, and the energy-saving effect is achieved. Compared with a traditional vibration conveyer, the vibration amplitude is larger, the vibration frequency is smaller, the vibration amplitude (ranging from 18 mm to 26 mm) of the energy-saving and environment-friendly vibrating conveyer is one third that of the traditional vibration conveyer, and friction between materials and the groove body is reduced to the maximum degree.

Technical field:

The present invention relates to a kind of conveyer, be specially adapted in granulated sugar manufacturing engineering, after candy, separated by secretion machine, after the granulated sugar in heaps secretion machine separated by its jigging conveyer disperse, make granulated sugar can enter equably a kind of energy-conserving and environment-protective jigging conveyer of next procedure.

Background technology:

State Patent Office's disclosed " jigging conveyer ", application number 200710132141.9, the one end that comprises base, cell body, driving device, swing arm, spring, cell body is feed end, the other end is discharge end, between driving device and cell body for being fixedly connected with, cell body is by swing arm and spring and base active link, driving device includes motor, small belt pulley, big belt pulley, belt, eccentric shaft, outer bearing carrier, inner pedestal, bearing, eccentric shaft and is solidly connected mutually with big belt pulley, and eccentric shaft is flexibly connected with outer bearing carrier and inner pedestal by bearing.Its shortcoming is, the Rocker connector that the structure of prior art adopts, and rocking arm only has support guide effect, and its rocking arm is passive work, but also need stay bearing plate, copper sheathing, bearing pin are as link, in use, copper sheathing and bearing pin wearing and tearing are very fast, and service life is short, and maintenance rate is high; What the transmission of prior art structure adopted is eccentric crankshaft, if in use damage has appearred in eccentric part, just needs integral replacing, has increased productive costs; And driving device designs below feed end, the shortcoming in design, will cause conveyor lengths longer, require the bulk strength of cell body larger, thereby ginseng is shaken weight with regard to corresponding increase, and power demand increases relatively; Because the cell body of this structure conveyer is open type, in convey materials process, material is tossed, unavoidably the powdery part in material is trickled down aloft, causes surrounding environment contaminated.

Summary of the invention:

Task of the present invention be propose a kind of amplitude large, shake frequently little, noise is low, power requirement is little, convey materials speed and the stable energy-conserving and environment-protective jigging conveyer of direction.

Task of the present invention completes like this, a kind of energy-conserving and environment-protective jigging conveyer, it comprises cell body, base, it is characterized in that: cell body is flexibly connected with base by vibration reduction support spring and board-like guide support spring, motor is arranged on the interlude below of cell body and installs, described motor is connected by key with the big belt pulley that is arranged on main shaft two ends, screw rod is connected with the bearing chamber at main shaft two ends with cell body bottom is symmetrical, compressed and form elasticity connection with friction top by spring bearing, spring bearing and cell body are fixedly connected.Described motor is connected with motor pulley, and motor pulley is connected with big belt pulley by cone belt.Eccentric bushing is equipped with in described main shaft one end, and excentric sleeve is to be fixedly connected with the main shaft being connected on described big belt pulley.Interval axle sleeve is housed between described excentric sleeve and big belt pulley and prevents radial runout, excentric sleeve is flexibly connected with outer bearing chamber and neck bearing chamber respectively by bearing and another bearing, axle external application jump ring is housed on excentric sleeve to be fixed, prevent the axial offset between outer bearing carrier and big belt pulley, bearing chamber is equipped with end cap outward, zerk is housed on end cap, on zerk, is equipped with and is with secondary lip outside framework oil seal.

The present invention has following effect: the technical program utilizes board-like guide support spring and power spring under dynamic action, can produce stronger bounce, the power that the more effective help driving device of this bounce energy provides conveyer, thereby reduce in working process, to motive requirement, to have played energy-conservation effect; Compared with the jigging conveyer of transmission, amplitude is large, little, the traditional jigging conveyer frequently that shakes adopts vibrating motor or vibration excitor driving force source more, its shake frequently large (960 beats/min), amplitude little (6-8mm), the conveyer that the technical program relates in normal operation, its amplitude (18-26mm) is 1/3 of traditional jigging conveyer, reduced to greatest extent the friction of material and cell body, the probability that makes material prototaxic destroyed by secondary reduces greatly.
