Abstract

The utility model provides an integrated grain-purchasing machine which can carry out moisture detection, impurity removing by separation, grade determining, weighing, etc. The utility model has the structure that a separation device for removing impurity, a volume grade determining weighing device and a continuous weighing device are arranged on one machine frame. The utility model is provided with a high moisture discharge valve, and can guarantee that the moisture content of purchased grains is in the national prescribed safety storage standard. The machine controlled by a micro computer can automatically carry out the processes of grade determining, weighing, settlement, accumulation and printing, alleviate the labour intensity of purchase staffs, and guarantee the accuracy of grade determining of purchased grains.

Description

Grain-purchasing machine

The utility model relates to a kind of integrated grain purchasing machine that moisture content detected, separated impurity elimination, fixed etc. and weighing that carries out.

At present in grain purchases, carry out water content detection, separate impurity elimination, processes such as fixed etc. and weighing, need to use multiple devices such as grain moisture content detector, removal of impurities tripping device and electronic scale, the grain purchases personnel labor intensity is big, and is difficult for guaranteeing that water content is all within the safe storage standard of national regulation.

The purpose of this utility model provides a kind of integrated grain purchasing machine that moisture content detected, separated impurity elimination, fixed etc. and weighing that carries out.

Task of the present utility model is finished as follows; It is with the removal of impurities tripping device, unit weight waits weigher and consecutive weighings device three parts to be installed on the same frame surely, on the center of the bottom of the grain feeding bucket of the tripping device of removal of impurities, a capacitance type foodstuffs moisture determination instrument is housed, there is a high moisture content discharge gate of being controlled by watery food tester the following bottom side of grain feeding bucket, the consecutive weighings device be installed in the removal of impurities tripping device put out cereal mouthful under on the position, removal of impurities separates puts the sampling gate that also has to be controlled by gate, unit weight wait surely weigher be installed in sampling gate under, unit weight waits weigher top that a constant volume tube is arranged surely, there is the electronic scales of a band tipping bucket its below, and there is a pipeline that leads to the grain feeding bucket of tripping device at the place of putting out cereal of tipping bucket.

Below in conjunction with accompanying drawing and provide execute example in detail concrete structure of the present utility model.

Fig. 1 is the structural representation of grain purchasing machine one embodiment.

Fig. 2 is the structural representation that the unit weight of grain purchasing machine waits weigher surely.

Referring to accompanying drawing, the tripping device 10 of removal of impurities, unit weight waits weigher 20 and consecutive weighings device 30 3 parts to be installed on the same frame 40 surely, on the center of the bottom of the grain feeding bucket 3 of the tripping device 10 of removal of impurities, a capacitance type foodstuffs moisture determination instrument 2 is arranged, there is a high moisture content discharge gate 1 that controlled by analyzer 2 the following bottom side of grain feeding bucket 3, consecutive weighings device 30 be installed in removal of impurities tripping device 10 put out cereal mouthfuls 9 under on the position, removal of impurities tripping device 10 also has a sampling gate 8 by gate control, unit weight wait surely weigher 20 be installed in sampling gate 8 under, unit weight waits the top of weigher 20 that a constant volume tube 22 is arranged surely, there is the electronic scales 26 of a band tipping bucket its below, and there is a pipeline 11 that leads to grain feeding bucket 3 at the place of putting out cereal of tipping bucket 25.One gate 27 is arranged at quantitation tube 22 bottoms, and the middle part has a plate 28 that tube is divided into two parts up and down, and the latter half of tube 22 is a standard volume, the outer vibration electromagnet 24 that is provided with of tube, and tube 22 tops have a control to close the photoelectric control photoelectric tube 21 of sampling gate 8.The removal of impurities tripping device 10 of this machine is to be made of chapelet 6, tornado dust collector 5, sack cleaner 4 and vibratory screening apparatus 7.

In when work, pour grain into grain feeding bucket 3, the part condenser type moisture teller 2 in the grain feeding bucket 3 of flowing through, when grain moisture content content exceeds the safe storage standard of national regulation, produce control signal, open high-moisture discharge gate 1, the too high grain of moisture is discharged from gate 1.When moisture is qualified, by chapelet 6 grain in the grain feeding bucket 3 is promoted, through tornado dust collector 5 and sack cleaner 4 two-stage dedustings, can improve working environment, carry out removal of impurities by high-speed oscillating sieve 7 again, enter 30 weighings of consecutive weighings device by the mouth 9 of putting out cereal, can directly send into silo by conveyor 50 behind the title, be convenient to realize the silo automatic management.When the need sampling waits surely, sampling gate 8 is opened in control, some grains are dropped in the constant volume tube 22 that unit weight waits device 20 surely by sampling gate 8, when grain is filled to photoelectric tube 21 positions, produce control signal and close sampling gate 8, open plate 28, electromagnet 24 vibrates, make the grain grain be pressed on constant volume tube 22 the latter halfs, close plate 28 then, the grain that has more is separated, then open constant volume tube gate 27, the grain of unit volume flows into from constant volume tube 22 in the tipping bucket 25 of electronic scales 26 and carries out weighing, tipping bucket 25 overturnings later, make grain turn back to grain feeding bucket 3 by pipeline 11, the constant volume weighing finishes.This machine each several part all adopts microcomputerized control, finishes the computing of grain money automatically, grades totally, prints, and be provided with power down protection.
