Abstract
The utility model relates to an automatic grain-selling unit, comprising a casing supporter 1, a pressure sensor 2, a hopper 3, a charging device and a control operation circuit board 6. With an electromechanical integration structure, the utility model adopts the pressure sensor to measure, with the advantages of easy operation and convenient using; the weighing precision reaches 1/1000, and the automatic grain-selling unit can be widely used for weighing the grain or analogous materials so as to reduce the workers' labor strength.
Description
The utility model belongs to a kind of poidometer, specifically it be a kind of dynamo-electric combination sell the grain device automatically.
For many years, the grain mode of selling of China's grain department is continued to use table scale metering always, artificial material loading form, and it is big to sell the grain personnel labor intensity, inefficiency.In order to address this problem, application number is to have introduced a kind of automatic weighing device in China's utility application prospectus of 88218682, and it constitutes jointly and can adorn the bucket that can unload by being placed in square hopper on the table scale and taper inclined tube.The taper inclined tube can before and after beat, again can be by the cover pike pole control in its outside, beat discharging in the time of having avoided dress to claim material.The taper inclined tube is beat forward, claims the thing discharging and affects the counter numeration, and beat then resets to be and feeds or light condition backward, and at beat simultaneously, top, top storaging bucket closes the charging valve/open, prevention/release material to be claimed.This apparatus structure more complicated, it is not too convenient to use.
What the purpose of this utility model provided a kind of electromechanical sells the grain device automatically, makes it have processing ease, easy to use, characteristics that degree of accuracy is high, to overcome the deficiencies in the prior art.
The purpose of this utility model can reach by following structure.The utility model has an outer casing stand, in the outer casing stand upper support pressure transducer is installed, a hopper is installed on the pressure transducer, the hopper top is the feeding port of feeding device, a material loading Electromagnetic Control valve is arranged on feeding port, a control operation circuit board also is installed on outer casing stand, and its input end connects with the electrical signal of pressure transducer by lead, and its control output end is connected with material loading Electromagnetic Control valve by lead.
Feeding device of the present utility model can adopt traditional high hopper, also can adopt the low level feed bin to add hoisting gear.For the utility model can both be extensive use of under various conditions, feeding device of the present utility model preferably adopts a kind of structure based on the spiral lifter, it comprises a hopper, one is positioned at the feeding port of spiral lifter upper end with hopper links by motor-operated spiral lifter and one.The spiral lifter is by a pipe, is contained in spiral fashion rotating shaft in the pipe and motor etc. and constitutes.The riser of spiral lifter can vertically be installed also tiltable and install.
Control operation circuit board of the present utility model is to be made of control circuit board and guidance panel etc.Its control circuit can adopt various automatic control circuits, preferably adopts the microcomputer control circuit with calculation function.In order further to improve the degree of accuracy of weighing, another control output end, road of the utility model control circuit is connected with the motor of feeding device, is used to control the rotating speed of motor.
So in use, key in the weight that needs weighing by the digital keys on the guidance panel earlier, display demonstrates the weight of key entry immediately, press starting switch, the material loading Electromagnetic Control valve of feeding device is opened, motor begins to rotate, feeding device promptly begins material loading, in the material loading process, pressure transducer converts the weight of expecting in the hopper to voltage signal at any time and sends into control circuit board, control circuit board shows charge weight by display on the one hand, compare with the weight magnitude of voltage of having set on the other hand, when charge weight during near setting weight, be that the voltage signal that pressure transducer produces approaches the setting weight signal, control circuit board promptly sends control voltage, close material loading Electromagnetic Control valve on the one hand gradually, the rotating speed of motor on the other hand slows down, make reinforced little reinforced process that progresses into, when charge weight equates with setting weight, control circuit board is controlled immediately and is closed material loading Electromagnetic Control valve and motor, display demonstrates the gravimetric value of material in the hopper simultaneously, and weighing is promptly finished.
Hopper blowing of the present utility model can adopt artificial blowing.For easy to use, the utility model can be installed a blowing Electromagnetic Control valve at the hopper drain hole, and its gauge tap is installed on the control operation circuit board.Like this, make blowing more convenient.
Electromagnetic Control valve in the utility model is meant with electric power and changes the mechanism that magnetic force opens and closes valve into that it comprises various motor control mechanisms, Electromagnetic Control mechanism etc.
Accompanying drawing has provided a specific embodiment of the present utility model, below in conjunction with the furthermore bright structure of the present utility model of accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.Among the figure, 1 is outer casing stand, support thereon pressure transducer 2 is installed, a hopper 3 is installed on pressure transducer 2, a blowing Electromagnetic Control valve 5 is installed on the drain hole 4 of hopper 3, feeding device is by hopper 7, form with spiral lifter 8 grades that hopper 7 links by motor 9 drives, one feeding port 10 that is positioned at above the hopper 3 is arranged in spiral lifter 8 upper ends, a material loading Electromagnetic Control valve 11 is installed thereon, 6 are the control operation circuit board, and its signal input part is connected by the voltage signal output end of lead with pressure transducer 2, its output terminal, one the tunnel is connected with material loading Electromagnetic Control valve 11, and another road is connected with motor 9.
The structure of metering of the utility model adopts pressure sensor and employing electromechanical, make the utility model processing ease, easy to use, its weighing precision reaches 1/1000, reached the purpose of this utility model, can be widely used in the weighing of grain etc. or similar material, lower working strength of workers greatly.
