Amplitude variation type vegetable and fruit separator
Technical field
The utility model relates to a kind of amplitude variation type vegetables and fruits separator.
Background technology
Along with the development of China's agricultural modernization, and the country to the great attention of agricultural and energetically the input, cause traditional small-scale, low technical, low value-added Agriculture Production Modes is towards production groupification, processing factory, the production and marketing mode-conversion of sales information.Wherein, in the middle of the process of batch production, Guangzhou granulated sugar tangerine is because individual little, and skin is thin, and quality is soft.The water chestnut profile is flat and quality is harder.The water content of west red date greatly easily causes machinery to hinder.The restriction of the complex contour of potato etc. factor causes suitable a part of vegetables vegetables and fruits can't finish at existing sorting machine the sorting of the size of mechanization.Heavy sorting work is all by manually finishing.Make this operation become the bottleneck that improves output.Output and the production cost of processing enterprise have been had influence on to a great extent.Enterprise can't run business big and strong in this field.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of specific duty is large, and sharpness of separation is high, and machinery-free is hindered, and applicability is a kind of vegetables and fruits mechanical sorting device widely.
The purpose of this utility model is achieved in that
A kind of amplitude variation type vegetables and fruits separator, frame, be provided with rotating shaft in the frame, be interval with a plurality of rotation belt pulleys on the rotating shaft, belt pulley has the vegetables and fruits hutch, described rotating shaft comprises the active rotation axle of an end and the driven rotating shaft of the other end, active rotation axle and driven rotating shaft all have two up and down, two active rotation axles pass through chain gear transmission, lower active rotation axle links to each other with motor, the active rotation axle includes the more piece transmission joint of interval setting and freely saves up and down, on the upper active rotation axle freely save and lower active rotation axle on transmission joint corresponding up and down, key is connected between the transmission joint and freely save and be equipped with a belt pulley, transmission joint and belt pulley, for driving torque, freely save with belt pulley between be connected by bearing, transmitting torque not, the length of driven rotating shaft is greater than driven rotating shaft, and the distance between the adjacent belt increases to driven rotation axle head gradually from the active rotation axle head.
Above-mentioned sprocket wheel comprises active rotation axle sprocket wheel and lower active rotation axle sprocket wheel, and the number of teeth between two sprocket wheels is different.
The utility model has been obtained following technique effect:
The utility model sharpness of separation is high, and machinery-free is hindered, and greatly improves the vegetables and fruits efficiency of separation, and the workload of being finished in 12 hours by 50 left and right sides workmans in the past utilizes the utility model all to finish in 4 hours, and the operator only needs two.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model apparatus structure.
The specific embodiment
A kind of amplitude variation type vegetables and fruits separator as shown in Figure 1, frame 3, be provided with rotating shaft in the frame, be interval with a plurality of rotation belt pulleys on the rotating shaft, belt pulley has vegetables and fruits hutch 4, it is characterized in that: described rotating shaft comprises the active rotation axle of an end and the driven rotating shaft of the other end, active rotation axle and driven rotating shaft all have two up and down, two active rotation axles pass through chain gear transmission, lower active rotation axle links to each other with motor, the active rotation axle 5 up and down, the 6 more piece transmissions that include the interval setting save and freely save, on the upper active rotation axle freely save and lower active rotation axle on transmission joint corresponding up and down, the transmission joint is equipped with a belt pulley 1 with freely saving, 2, key is connected between transmission joint and the belt pulley, is used for driving torque, freely save with belt pulley between be connected by bearing, transmitting torque not, the length of driven rotating shaft is greater than driven rotating shaft, and the distance between the adjacent belt increases to driven rotation axle head gradually from the active rotation axle head.Described sprocket wheel comprises active rotation axle sprocket wheel and lower active rotation axle sprocket wheel, and the number of teeth between two sprocket wheels is different.
Teeth number of sprocket is different up and down, and then the rotating speed of active rotation is also different up and down, and the linear velocity of belt conveyor is not identical yet.When the vegetables and fruits vegetables rest on the different belt of two movement velocitys like this, can be because its spin of speed official post of belt.This design concept is to produce accumulation stack because the material loading amount is large at separator in order to eliminate, and the vegetables and fruits vegetables is produced when sorting bypass the immediate leadership, the generation of sharpness of separation decline phenomenon.Such as, the belt conveyor on the separator arranges to have certain angle between the every belt, i.e. not parallel layout radially.Like this belt conveyor every 700mm apart from the time spacing between adjacent two conveyer belts will increase 5mm.Being that the adjacent two conveyer belt spacings of start position are 65mm, then is 70mm in the location gap of 700mm backward, and the location gap of 1400mm is 75mm.The rest may be inferred, increases progressively gradually to finish the ascending sorting work of vegetables and fruits vegetables by spacing between the conveyer belt.
