Description
Technical field
The present invention relates to a kind of conveyer belt, the Fructus Lycopersici esculenti stem fruit adjusting running parameter especially in accordance with load weight change separates conveyer belt.The present invention has compact conformation, easy to control, the feature of self-adaptative adjustment running parameter.
Background technology
Xinjiang is the main place of production of Tomato in China production and processing, and cultivated area and yield are being continuously increased in recent years, and mechanization is gathered becomes the major way of Fructus Lycopersici esculenti results.
At Chinese patent " tomato harvester (application number: the CN201210029978.1 that differential belt type Fructus Lycopersici esculenti results segregation apparatus and this device are constituted, publication number: CN102577744A) " disclose a kind of differential belt type Fructus Lycopersici esculenti results segregation apparatus and the tomato harvester that constitutes of this device, Fructus Lycopersici esculenti results segregation apparatus comprises a plurality of endless belt-shaped or chain form body being parallel to each other, the outer rim of endless belt or chain form body is provided with the finger-like ratch of setting for one week, the described a plurality of endless belt being parallel to each other or chain form body is alternate is divided at least two groups, and endless belt two groups parallel or chain form body are provided with each different main drive wheels, main drive wheel axle and driving mechanism.For realizing separating and the results of fruit fruit and seedling, use relatively low frequency of vibration work, produce the soft shape that tears by the relative displacement between adjacent endless band or chain form body and complete separation；At Chinese patent " tomato harvester (application number: the CN201010578923.7 that swinging Fructus Lycopersici esculenti results segregation apparatus and this device are constituted, publication number: CN102077733A) " disclose swinging Fructus Lycopersici esculenti results segregation apparatus and the tomato harvester that constitutes of this device, including Grid screen, Grid screen top is provided with conveying vibrating device, this conveying vibrating device comprises two sprocket drums and sprocket drum upper sprocket wheel and chain, chain is transversely provided with elastic claw bar, elastic claw bar is provided with elastic claw, return spring and swing arm, it is simultaneously provided with runout mechanism, this runout mechanism comprises one group of runout sprocket wheel and runout chain, runout chain is provided with dentation projection.Frequency of vibration is high and adjustable amplitude and easily-controllable, vibrating effect good.But above two Fructus Lycopersici esculenti stem end segregation apparatus all cannot realize the size adaptation according to Fructus Lycopersici esculenti conveying capacity and adjust the function of running parameter, and energy loss is bigger.
Carry out in the conveyer belt that stem fruit separates at tomato harvester, operating rate cannot be adjusted by existing separation conveyer belt according to conveying capacity, cannot be sufficiently separated when conveying capacity increases, cause that stem end separating effect is low, even there is blocking the phenomenon of segregation apparatus, unsegregated part also needs to manually pick up separation in field, and labor intensity is big, consumes too much manpower.So needing to develop one namely can complete stem end separation, the separation conveyer belt of running parameter can be changed again according to load change.
Summary of the invention
It is an object of the invention to provide a kind of running parameter separating conveyer belt that automatically can be adjusted by hydraulic control system according to load weight change to reach the load-sensing separation conveyer belt of optimal separation effect.

Described load-sensing separation conveyer belt, described drive sprocket set 12 and driven chain wheels 1 are respectively provided on driving shaft 11 and driven shaft 2, between be wound with chain group 13.
Described load-sensing separation conveyer belt, is uniformly provided with some chain arm-ties 14 between described chain group 13, described chain arm-tie 14 be provided with rubber moving tooth 15 and and the link of described chain group 13 between be connected by bolt 19.
Described load-sensing separation conveyer belt, described LOAD CELLS 3 one end is connected with load weighing device, and the other end is connected with controlling module 5；Described speed probe 4 one end is connected with driving shaft 11, and the other end is connected with controlling module 5.
5, conveyer belt according to claim 1, it is characterised in that described hydraulic motor 10 is two-way hydraulic motor.
The operation principle of the present invention is as follows:
During tomato harvester work, Fructus Lycopersici esculenti stem end unsegregated after cutting is transported to load-sensing separation conveyer belt by inclined conveyer belt, the fruit separated is by carrying the space of interband to implement the collector for fruits of lower section, and the cane after separation is carried backward by separating conveyer belt, dishes out from machine rear portion.Load-sensing separation conveyer belt by hydraulic motor with the rotation in the positive and negative both direction of action, the rotating speed of hydraulic motor and commutating frequency send signal and control the switching frequency of proportional reversing valve spool and valve port opening controls by controlling module, hydraulic motor rotating speed in positive and negative both direction and commutating frequency is changed by controlling flow, namely have adjusted and separate the frequency of vibration of conveyer belt and amplitude, if to being n along the machine reciprocal rotating speed that advances1, the rotating speed along the direction of machine travel is n2, n1> n2, ensure that conveyer belt has been shaken stem end and separated and carry separated cane backward along machine advance opposite direction with this.The load that separation conveyer belt bears is measured by load weighing device, the weight recorded is converted to voltage signal and is sent to control module, drivewheel tach signal is converted to voltage signal and is sent to control module by speed probe, control module by weight voltage signal, the comparison operation of speed voltage signal, rotating speed in the aperture of control proportional reversing valve and the positive and negative both direction of hydraulic motor, and then control to separate frequency of vibration and the amplitude of conveyer belt, working parameters of automatic adjusting is to adapt to different loads operating mode, thus improving stem end separation efficiency, improve productivity ratio.
