Description

Rice-wheat thresher

The utility model relates to a kind of thresher machine, particularly relates to the thresher of a kind of paddy rice, wheat.

Now, its basic function of rice wheat thresher of generally using in western part is that threshing and belt jet are winnowed.Mainly grade and constitute by winnow device and power transmission part of Ratch type threshing cylinder, belt, it is the high-speed motion that utilizes the flat pattern band that the belt jet is winnowed, the mixture that leaks is thereon tossed away at a high speed, because the quality difference of things such as the short-and-medium cane of mixture, clever shell, broken leaf, seed, the inertia force that produces is also inequality, under the effect of wind-force, impel seed and other separating substances simultaneously.At this moment, clean seed is dished out beyond ten meters in the machine, collects by manually going afterwards again.The shortcoming of this type is take up room big, place bad adaptability, and place flatness, cleannes are had relatively high expectations, and flow chart is numerous and diverse, it is more to need with manpower, and labour intensity is bigger, the peasant's that is far from suitable demand.

At present; someone has done improvement to a kind of paddy-eliminator; as the patent No. is 96205519.0; name is called " bleed type thresher "; it is to be provided with one to blow sack-filling device on original structure; this device is made up of wind blower and the row's grain airduct that has funnel; row's grain airduct of band funnel is arranged on the bottom of vibration sifting bed; by motor and belt drive unit directly to the wind blower outputting power; make its grain of rice that falls into by the bag of packing into of the discharging cover on the row grain airduct; inner chamber is provided with the Lysimachia sikokiana shift fork and the device of winnowing is formed in the blade cooperation in that disorderly careless straw are winnowed; and the wind box that has disorderly careless straw outlet and light weeds straw to export; can once finish threshing, the classification Lysimachia sikokiana; functions such as automatic bagging.

Above bleed type thresher is though can finish functions such as threshing, classification Lysimachia sikokiana, automatic bagging, its complex structure, phenomenon such as manufacturing process is loaded down with trivial details, and cost is higher, and consumption of power is big.

The purpose of this utility model just provide a kind of simple in structure, clean thoroughly, the rice-wheat thresher of automatic bagging.

Order of the present utility model is achieved in that it comprises feeding platform, loam cake, threshing cylinder, notch board, frame, grass outlet, blower fan, sieve system, screw feeder winnow, various slide cotton thread and road wheel etc.The feeding platform is connected in the front end of frame; The loam cake intrados is welded with spiral deflector, and threshing cylinder is installed on the frame by bearing block support, and notch board is the grid type structure, be the semicylinder shape, be installed in threshing cylinder below, be connected on the frame with loam cake, form the cylindrical shape of a sealing, constitute threshing chamber; Frame is the pestle shelf structure; Grass outlet is at the end of threshing cylinder, and blower fan is made up of two crusts of weathering, and the fan rotor both sides are equipped with bearing block, and are fixed on the frame, and the crust of weathering is connected with slide carriage, frame; The sieve system be positioned at notch board following, screw feeder above, and be arranged in parallel with the blow-off outlet of blower fan is approximate, the sieve system is made up of sieve nest and transmission mechanism etc., sieve nest is that double deck screen structure, top sieve are the flake sieve, sieve is the plane stamped sieve down; Belt pulley is located on the cylinder shaft, and belt pulley is connected with the blower fan axle, raises inlet right leather belt wheel, and eccentric pulley is connected with sieve nest by connecting rod again; Raising inlet right leather belt wheel is connected with screw conveyor shaft, the screw feeder winnow is made up of screw feeder and winnow, screw feeder is welded by helical blade and axle, two ends are equipped with bearing, the screw feeder groove is a semi arch flute profile structure, be positioned at screw feeder below, the screw feeder semi-surrounding is got up, screw feeder be positioned at sieve below, winnow is sent blade, the shell of winnowing, is connect grain mouth and sack automatic clamping device etc. and form by throwing, throwing send blade and screw feeder coaxial, connects the grain mouth delivery plate screw feeder winnow that a place is provided with on the shell circumference of winnowing and is fixed on the frame; Slide carriage road wheel part is made up of two fast pulleys and a directive wheel, and there is pull bar the directive wheel front.

The utility model compared with prior art, its advance is:

1. this machine send the vane type materials auto-feeder for bag owing to be provided with throwing, its simple in structure, dependable performance makes in the disposable bag of packing into automatically of seed after cleaning, and significantly reduces flow chart, reduce labor intensity, realized cheating recessed place, the requirement that all kinds of crops carry out threshing is carried out at the narrow edge of a field.And, more save a manpower than patent 96205519.0 because this machine has designed the sack automatic clamping device meeting grain mouth place.

2. this machine utilizes pneumatic jig formula cleaning plant, not only dries and cleans, and carry out secondary sieve screening, and the grain cleaning rate after cleaning is reached more than 98.3%, can directly store or sell, and needn't carry out the secondary separation of manually winnowing again.Clean thorough, reliable operation, advanced in performance, be more suitable for vast farmers friend's demand.
