Description
The utility model relates to a kind of agricultural grain separator, especially a kind of agricultural light thresher machine that can separate millet straw fully.
Interim season when harvesting, for the rifle time, strive speed, the cereal that must as early as possible harvesting be come carries out threshing, put in storage after drying, otherwise, will bring loss to the grain of having a good harvest.Though at present various thresher machines such as manual, motor-driven are arranged, when carrying out threshing, also things such as weeds can be squeezed in the grain tank with these machineries, can not make it once to separate automatically, the labour intensity that this has just strengthened the peasant is unfavorable for improving labour productive forces.Chinese patent 97208260.3 discloses a kind of " the fixed net type millet straw separates Portable rice threshing machine ", it is in the roller bottom one vibration screen to be set, vibration by screen cloth separates millet straw, but because this screen cloth very easily blocks straw, and by manually carrying out threshing, both wasted time and energy, millet straw thoroughly can not be separated again, and also influence operating efficiency, therefore still can not satisfy the requirement of agricultural modernization.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of power thresher that millet straw can be separated fully is provided.
Another purpose of the present utility model is to provide a kind of thresher screen cloth.
The utility model is realized by following technical proposal: it is by frame, be located at the roller which is provided with the threshing tooth in the frame, be located at the vibration screen of roller bottom, and the engine that drives roller rotation and screen cloth vibration constitutes, it is characterized in that also being provided with on the frame grain-straw separating device, so that the millet straw after threshing, the vibration separation is separated fully.Described grain-straw separating device comprises at least one group of fan propeller of being located on the roller, and this blade rotates with the rotation of roller, is used for the millet straw that splits away off is blown away from slag notch, carries out the first time and separates; Described grain-straw separating device also comprises the fan blower of being located at the outside grain tank of frame side, and this fan blower links to each other with power shaft by transmission device, so that under same engine drives blower fan is rotated, thereby remaining millet straw is blown away, and realizes separating for the second time.Described engine is a marketable gasolines machine, the power shaft of this machine is provided with two belt pulleys, by two driving-belts respectively with thrashing roller on rotating shaft rotating shaft links to each other with fan blower, the startup gasoline engine, can drive roller and fan blower simultaneously and rotate, realize the threshing of paddy and the separation of millet straw.The rotating speed of gasoline engine can be regulated by throttle in addition, and its rotating speed is 2000-4000 rev/min.
Another purpose of the present utility model is finished by following technical proposal: it is made of a metal hole pattern, it is characterized in that described metal hole pattern comprises a sheet metal, and is obliquely installed a plurality of holes on this sheet metal.Wherein the angle on the axial line of hole and metallic plate plane is 20-35 °, snaps in when avoiding millet straw to fall in the hole and can't realize screening, so that increase work efficiency.Described metal aperture Netcom crosses the back shaft of being located at its underpart and fixes, the back shaft two ends are fixed on the frame, this back shaft is connected with flexible axle, the other end of flexible axle is located on the belt pulley in the roller rotating shaft by eccentric wheel, so that under rotating shaft drives, make screen cloth do the vibration of vertical direction by flexible axle, make cereal fall into the Gu Douzhong of screen cloth bottom, millet straw then makes it discharge from slag notch by the fan propeller on the roller.
The utility model compared with prior art has following advantage and good effect: because fan propeller is set on roller, and be provided with fan blower in the grain tank side, can be in threshing, millet straw is carried out first separation, and in the dropping process after the cereal screening, make remaining millet straw obtain secondary separation, therefore, under the situation that does not increase power set, millet straw can be separated fully with cereal, obtain clean full grain.In addition because screen cloth adopts the hole pattern with angle of inclination, and the motion mode of screen cloth is the vibration on the vertical direction, therefore, and effective sieving cereal, and can not make millet straw obstruction hole pattern, guarantee operating efficiency.In addition, these facility have characteristics such as simple in structure, light and flexible, energy savings, time and labour saving, are the comparatively desirable rural area apparatus of a new generation.
