Abstract
A multifunctional thresher belongs to agricultural machinery and is used for threshing legume crops and recovering beans mixed in straws and seed-case fragments. The multifunctional thresher comprises a threshing drum of an existing thresher, a threshing roller inside the threshing drum, a vibration screen and a straw and seed-case fragment suction and separation fan above the vibration screen, wherein the vibration screen positioned below the threshing drum extends forwards. The modification of the multifunctional thresher includes that a cylindrical bean and fragment centrifugal separating drum is vertically mounted on the threshing drum, an air inlet arranged on one side of the lower portion of the centrifugal separating drum enters in a tangential direction, a radial air outlet is arranged at the upper end of the centrifugal separating drum and on the same side with the air inlet, the upper end of the centrifugal separating drum is closed while the lower end is communicated with the threshing drum, and an air duct is connected between an exhaust outlet of the suction fan and the air inlet of the centrifugal separating drum. The multifunctional thresher has the advantages that beans in fragments discharged from the fragment suction fan return to the threshing drum after the fragments enter the centrifugal separating drum, and straws and the seed-case fragments finally discharged from the air outlet of the separating drum contain no beans, thereby the multifunctional thresher eliminates food waste in threshing work.
Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to a kind of thresher.
Background technology
Existing thresher; legume crop thresher particularly; comprise that seed and stalk, kind shell impact the threshing tube; toothed threshing roll in the threshing tube; be positioned at below the threshing tube and the reciprocating sieve that stretches out forward; be installed in reciprocating sieve and be longer than the stalk of threshing tube part compass screen surface top, plant shell debris-suction separation blower fan, form with seed container or conveyer that the reciprocating sieve output is connected mutually.
Though the thresher of said structure can more successfully be finished the threshing operations of legume crop; become modular system; but find stalk in using, plant in the chip that shell debris-suction blower fan chip outlet discharges and have the part beans to be mixed in wherein; through the chip that is mixed with beans is retained and the manual sorting, the seed of sneaking in the chip that sucktion fan is discharged be separating sieve output output seed 2%.It is the phenomenon of a waste grain that merits attention.Adopt adjustment blower fan inlet scoop and compass screen surface distance or wind speed to mix beans and reduce or eliminate, can cause the reduction of the chip separating effect in the beans on the compass screen surface again.
The purpose of this utility model provides a kind of multi-functional thrasher; be used for the legume crop threshing, keep sucktion fan to compass screen surface under the situation of chip separating effect, reclaim and be mixed in stalk, plant the beans in the shell chip; eliminate waste, increase the grain yield in the threshing course.
The utility model comprises the threshing tube of existing this type of thresher, and the band tooth threshing roll in the threshing tube is treated threshing crop input port, stalk outlet, seed outlet on the threshing tube.Be positioned at below the threshing tube and the reciprocating sieve that stretches out forward, being installed in reciprocating sieve is longer than the stalk of threshing tube part compass screen surface top, plants shell debris-suction separation blower fan, the improvement of being done is at threshing tube upside cylindrical shape beans and chip centrifugation tube to be installed vertically, the air inlet that centrifugation tube vertical direction bottom one side has tangential direction to enter, centrifugation tube upper end is higher than the air inlet position radially exhaust outlet.Centrifugation tube upper end closed, the lower end is communicated with the threshing tube through pipeline, connects the air channel between sucktion fan exhaust outlet and centrifugation tube air inlet.More than be basic scheme of the present utility model.
It is that the exhaust outlet of centrifugation tube upper end is that one section width equals centrifugation tube diameter, the rectangular channel of outstanding cylinder side radially that the chip that the centrifugation tube exhaust outlet that is to put together is discharged, the utility model further improve.
The beneficial effects of the utility model are: the chip that carries in air-flow that the debris-suction blower fan is discharged and the air-flow is after the air channel enters the centrifugation tube; heavier beans moves and is back to the threshing tube at the pipeline through between cylinder and threshing tube under the action of gravity along barrel; entering the cylinder chip rises under air-flow drives; discharge from air exhaust passage; finally no longer be mixed with beans the stalk of discharging, the kind shell chip from air exhaust passage; compare with existing thresher; the grain of the more than enough recovery 2% of energy has been eliminated the waste of grain in the threshing operations.

Embodiment
Consult Fig. 1; treat threshing crop input port by having; larger particles stalk, kind shell bits outlet; seed outlet threshing tube 1; band tooth threshing roll 2 in the threshing tube; the vibrations separating sieve 3 that is positioned at below the threshing tube and extends forward is installed in the vibrations separating sieve and is longer than the stalk of threshing tube part compass screen surface top, plants that the shell debris-suction is separated blower fan 4 and driving mechanism is formed the thresher that is same as prior art.Consult Fig. 1 to Fig. 4, cylindrical shape beans and chip centrifugation tube 5 vertically be installed at threshing tube upside, the air inlet 6 that centrifugation tube bottom one side has tangential direction to enter, the air inlet homonymy that centrifugation tube upper end is higher than the air inlet position has width to equal one section of the centrifugation tube diameter radially exhaust outlet 7 of rectangular channel form, centrifugation tube upper end closed, the lower end is communicated with the threshing tube through conically shaped and pipeline 8, connects air channel 9 between sucktion fan exhaust outlet and centrifugation tube air inlet.
Claims (2)
1. multi-functional thrasher; comprise the threshing tube; band tooth threshing roll in the threshing tube; treat threshing crop input port on the threshing tube; the stalk outlet; the seed outlet; be positioned at below the threshing tube and the reciprocating sieve that stretches out forward; be installed in reciprocating sieve and be longer than the stalk of threshing tube part compass screen surface top; plant the shell debris-suction and separate blower fan; it is characterized in that: cylindrical shape beans and chip centrifugation tube vertically are installed at threshing tube upside; the air inlet that centrifugation tube vertical direction bottom one side has tangential direction to enter; centrifugation tube upper end is higher than the air inlet position radially exhaust outlet; centrifugation tube upper end closed; the lower end is communicated with the threshing tube through pipeline, connects the air channel between sucktion fan exhaust outlet and centrifugation tube air inlet.
2. multi-functional thrasher according to claim 1 is characterized in that: the exhaust outlet of centrifugation tube upper end is that one section width equals centrifugation tube diameter, the rectangular channel of outstanding cylinder side radially.
