Specific embodiment

The present invention is illustrated in further details with reference to the accompanying drawing.

A kind of low-energy-consumptienvironment-friendlyhigh-precision environment-friendlyhigh-precision crop dryer, including chassis 1, row grain layer 2, drying layer 3, tempering layer 4, elevator 5, Spread grain machine structure 6, control system 7, exhaust fan 8, it is characterised in that: 5 top of elevator and spread between grain machine structure 6 it is tilting have on Flow tube 10, tilting between 2 lower section of row's grain layer and 5 bottom of elevator to have down-pipe 20, boosted machine 5 is promoted to top by upper flow tube 10 The cereal in portion, which is guided to, to be spread in grain machine structure 6, and down-pipe 20, which will arrange the cereal that is discharged of grain layer 2 and be guided to 5 bottom of elevator, to follow Ring.Core of the invention is to effectively prevent cereal upper instead of traditional auger transport model up and down by upper and lower flow tube Lower auger receive extruding when conveying and caused by physics it is broken, improve the percentage of head rice of cereal, ensure that it is dry after cereal product Matter.Furthermore by the design for eliminating traditional conveying auger up and down, the use of two auger motors is saved, is greatly reduced Consumption of the machine for electric power, reduces energy consumption.When it is implemented, the boosted machine 5 of cereal is promoted at the top of machine, at upstream It flows to and is spread in grain machine structure 6 under the guide functions of pipe 10, then through tempering layer 4, drying layer 3, row's 2 row's grain of grain layer to down-pipe 20, then cereal is guided to 5 bottom of elevator by down-pipe 20 and is delivered up, it is entirely recycled to complete one.

Further, the whole tubulose that is square of the upper flow tube 10, and the cross section of the rectangular tube is from elevator 5 to spreading grain 6 direction of mechanism is gradually reduced.When it is implemented, the big section end of upper flow tube 10 is connected with elevator 5, small bore end and grain machine is spread Structure 6, is designed by non-constant section, be can effectively avoid cereal and is blocked in upper flow tube 10, is that cereal uniformly falls into and spreads grain In mechanism 6.

Further, dust removal port 11 is offered on the upside tube wall of the upper flow tube 10, upper dust removal port 11 is removed on Dirt pipe 12 is connected with discharge pipe.Specifically, cereal is influenced when sliding from top to bottom along upper flow tube 10 by gravitional force, on cereal The dust of attachment can be detached from cereal and spread in pipe, cause dust in air content to increase, influence air quality.Pass through upper dedusting The design of mouth 11, can be siphoned away most of dust using the suction of blower, so that cereal is kept cleaning, a large amount of dirt accumulations is avoided to exist Machine is interior or is diffused into influence machine surrounding enviroment outside machine.

Further, it is provided with lower hopper 30 below row's grain layer 2, is provided with down at the bottom discharge port of lower hopper 30 The upper end of flow tube 20, down-pipe 20 is connect with lower hopper 30, and the lower end of down-pipe 20 is connect with the bottom sides of elevator 5.It is logical Cross lower hopper 30 carry out row grain layer 2 be connected with the blanking between down-pipe 20, structure is simple, easy to make.

Further, the down-pipe 20 is whole in Y-shaped, including the main feeder pipe connecting with 30 bottom of lower hopper 21, main 21 lower end of feeder pipe is divided into two as feeder pipe 23 and discharge duct 22, the lower end of feeder pipe 23 and the bottom side of elevator 5 Face connection, feeder pipe 23 and 22 junction of discharge duct are provided with material distributing valve 24.When it is implemented, discharging is arranged on down-pipe 20 Pipe 22 controls the opening and closing of feeder pipe 23 or discharge duct 22 by material distributing valve 24.When machine is in grain dry state, sub-material Valve 24 closes discharge duct 22, so that cereal is flowed into elevator 5 from feeder pipe 23 and is recycled；After the completion of grain dry, material distributing valve 24 close feeder pipe 23, flow out cereal directly from discharge duct 22 and carry out unloading, unloading is simple and convenient, is more in line with the need of client It asks.

Further, peep hole 231 is offered on the feeder pipe 23.By offering peep hole on feeder pipe 23 231, convenient for during machine operation user grain dry situation is observed；Meanwhile user also can use it is portable Moisture teller is sampled at peep hole 231, measures the real-time moisture content of cereal.

Further, the side of the lower hopper 30 offers lower dust removal port 31, and lower dust removal port 31 passes through lower dust removing tube 32 It is connected with discharge pipe.Specifically, cereal is influenced when falling in lower hopper 30 by gravitional force, the dust adhered on cereal can take off It is spread in hopper from cereal, causes dust in air content to increase, influence air quality.By the design of lower dust removal port 31, Most of dust can be siphoned away using the suction of blower, make cereal keep cleaning, avoid a large amount of dirt accumulations in machine or Being diffused into outside machine influences machine surrounding enviroment.

Further, the drying layer 3 includes two drying boxes 40, two 40 arranged for interval of drying box and in two dryings The gap 41 moved towards front and back is formed among case 40, the air-flow trend of cornue is vertical with 41 direction of gap in two drying boxes 40, heat Wind is entered after drying layer 3 by gap 41 to flow out through cornue to two sides.Specifically, drying layer 3 is designed using split type drying box, So that hot wind enters from the gap 41 among two drying boxes 40, the cornue then through two sides drying box 40 is guided to be arranged to two sides Out, the drying distance of hot wind is greatly reduced, effectively reduces the energy loss of hot wind in drying process, is improving drying efficiency While reduce energy consumption.

The working principle of the invention is: the boosted machine 5 of cereal is promoted at the top of machine, under the guide functions of upper flow tube 10 Flow to and spread in grain machine structure 6, then through tempering layer 4, drying layer 3, row's 2 row's grain of grain layer to down-pipe 20, then by down-pipe 20 Cereal is guided to 5 bottom of elevator to be delivered up, is entirely recycled to complete one.Upper and lower flow tube 10,20 is instead of biography System auger transport model up and down, effectively prevent cereal received when upper and lower auger convey extruding and caused by physics be crushed, The percentage of head rice for improving cereal, the grain quality after ensure that drying, saves the use of two auger motors, greatly reduces Consumption of the machine for electric power, reduces energy consumption.In machine operation procedure, suction function of the upper and lower dust removal port 11,31 in blower Under siphon away dust on cereal, so that cereal is kept cleaning, avoid a large amount of dirt accumulations in machine or be diffused into shadow outside machine Ring machine surrounding enviroment.

Using of the invention novel up and down without auger drying machine, 1.2KW is reduced compared with general power for conventional dryer, by one Grain dry to the moisture content that the initial moisture content in storehouse is 24% is 14%, probably needs 13h, then has been dried using drying machine of the invention One storehouse cereal can save the electricity of 15.6KW/h, and total energy consumption reduces by 7.7%.
