Description

A kind of apparatus of selecting rice color

Technical field

It the utility model is related to grain of rice processing unit technical field, more particularly to a kind of apparatus of selecting rice color.

Background technology

Rice is the main food in people's life, and there is grass-seed, rotten rice, insect pest rice, rice etc. are different in rice Color tablets, they are separately pretty troublesome, and apparatus of selecting rice color is can be by yellow rice kernel, red grain rice, white belly rice, dead rice, the rice that goes mouldy, black A kind of light harvesting that the heterochromatic particulate contamination such as the abnormal rice kernels such as scab rice and sandstone, soil block is rejected from non-defective unit rice, superior rice, The technology such as mechanical, electrical, pneumatic is in integral modernization, high-tech grain processing equipment.

Selected rice feed hopper enters machine, and by the vibration of vibrator assembly, selected rice glides along passage, under acceleration Fall behind the observation area entered in separation chamber, and passed through between sensor and background board, in the presence of light source, according to the strong of light Weak and color change, system is produced the work of output signal drive magnetic valve and heterochromatic particle be blown in the waste chamber of receiving hopper, And non-defective unit rice and superior rice drop down onto receiving hopper finished product intracavitary under continuing, so as to reach the purpose of screening.

Due to being formed through hull paddy and husk rice etc. in rice process in paddy and inclusion of dirt and impurity understood in transportation, During color sorting, dust and other impurity being easily attached on glass can be attached on sight glass, when the ash on sight glass Dirt or impurity or it is more when, through sight glass to rice carry out sort detection electro-optical system will easily produce the chain types such as flase drop Chain problem, gently then, color sorting band ratio selected to colourity has an impact, heavy then cause valve frequent operation, reduces nozzle and its control Lifetime of system processed, which shortens, even burns Jet control system.

The dust and the purging system of impurity of the prior art of removing includes cylinder and glass wiper, glass wiper peace Loaded on cylinder, timing is reached clearly by controlling cylinder valve to switch pusher cylinder piston and slide by turn-key system at preset timed intervals Sweep the effect of dust impurity on glass pane.

But the purging system simply peels off impurity dust from sight glass, and the impurity dust being stripped can also It is present in machine, is easily again attached on sight glass, Gu its purging system cleaning effect is not thorough.

Utility model content

The purpose of this utility model is to provide a kind of apparatus of selecting rice color, has after the impurity dust on sight glass is taken out It is collected, prevents it to be again attached on sight glass, improves the purpose for cleaning effect.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of apparatus of selecting rice color, including frame, the sight glass that is installed in frame, it is provided with for clear in the frame The dust arrester of dust on glass pane is swept, the dust arrester includes dust absorption arm, is communicated in dust absorption arm and extends to outside frame Dust removing tube, be installed in dust removing tube component and fan assembly be collected by filtration, several suctions are offered on the dust absorption arm Dirt mouth, it is provided with the frame and drives the reciprocating reciprocating member of dust absorption arm sight glass.

Pass through above-mentioned technical proposal, reciprocating member drive dust absorption arm to be moved reciprocatingly along sight glass surface, fan assembly Suction is provided for dust absorption arm so that dust absorption arm collects dust into dust removing tube, and then fan assembly drives inclusion of dirt impurity Gas stream be collected by filtration after component is filtered and be emitted into outside frame, prevent the dust after being peeled off to be adhered to form again On glass, the cleaning effect to sight glass is improved.

Further, the reciprocating member includes being fixedly connected on the main installation in frame and being placed in below sight glass Frame, the reciprocating screw rod for being rotationally connected with main mounting bracket, the guiding for being fixedly connected on main mounting bracket being be arranged in parallel with reciprocating screw rod Bar, it is installed on the motor for being used for driving reciprocating screw rod to rotate on main mounting bracket and is fixedly connected on dust absorption arm and is sheathed on and lead To bar, screw thread is matched with the contiguous block of reciprocating screw rod simultaneously.

Pass through above-mentioned technical proposal, after motor is opened, reciprocating screw rod rotates, and drives and inhales with the contiguous block that reciprocating screw rod coordinates Dirt arm moves back and forth along sight glass, so that dust absorption arm carries out comprehensive dust suction cleaning to sight glass.

Further, secondary mounting bracket is installed above the sight glass, be provided with the secondary mounting bracket and guide rod Parallel fix bar, the slip ring for being fixedly connected on dust absorption arm is arranged with the fix bar.

Pass through above-mentioned technical proposal, is synchronized with the movement with contiguous block and the position of dust absorption arm is fixed mating connection block, Prevent dust absorption arm from causing contiguous block to push against in reciprocating screw rod due to swinging.

Further, the dust removing tube includes being communicated in the adjustable pipe of dust absorption arm, is sheathed on movable tube end and screw thread is matched somebody with somebody Connecting tube together in adjustable pipe, connecting tube and the discharge pipe extended to outside frame are threadedly connected to, it is described that component peace is collected by filtration Loaded in connecting tube, the fan assembly is installed in discharge pipe.

Pass through above-mentioned technical proposal, adjustable pipe move reciprocatingly with dust absorption arm, and component and fan assembly difference is collected by filtration It is installed in connecting tube and discharge pipe, it is convenient to be installed, changed, cleaned and repaired to component and fan assembly is collected by filtration.

Further, it is described be collected by filtration component include be arranged in adjustable pipe and with activity pipe screw thread coordinate adapter sleeve, It is fixedly connected on the collecting bag of adapter sleeve.

Pass through above-mentioned technical proposal, collecting bag carries out the filtering of dust impurity to the gas of process, and dust impurity is received Combine in collecting bag, when needing to clean collecting bag, connecting tube is departed from into adjustable pipe and discharge pipe, and be rotatablely connected set Adapter sleeve and collecting bag is set to depart from adjustable pipe.

Further, the air-out tube end is provided with the non return part for preventing being blowed wind into outside frame in frame.
