Description

Corn threshing machine of light-weight type

The utility model belongs to a kind of light-duty corn threshing machinery device.

Existing light-duty corn threshing machinery has manpower facility and two kinds of structures of dynamic power machine.For example China's patent CN2033578U propose a kind of on main shaft " threshing cut into slices dual-purpose machine " of band section cutterhead promptly be the corn threshing facility of personnel selection masterpiece power; its sheller unit comprises charging skylight, support, main shaft, threshing cylinder, fishback, bearing block, big frame and handle; during corn threshing; iblet leaks down from the fishback gap by deadweight; corncob then can take out from the charging skylight by staff, and this machine is suitable for peasant's use in unregulated power area still.Shortcoming is that this complete implement structure once can only the several corn ear of threshing, and work efficiency is too low, and threshing performance is not high yet.China patent CN88219520U disclosed " light-duty husker sheller " belongs to the dynamic power machine sheller unit; by frame; engine; belt drive unit; break away from the chamber and have the power transmission shaft of bearing supporting and contain and roll bar; gear hobbing; the rolling thrasher each several part of fastening disk is formed jointly; this machine work efficiency height; energy consumption is low; the threshing performance height; the advantage that breakage rate is low; and the corn flesh is directly separated with iblet; weak point is could send through small slide plate after the minority iblet must sift out through the sieve of row's corn flesh, has increased the structure of making this machine and the complexity of technology.

The purpose of this utility model provide a kind of compact conformation, volume little, be easy to move lightweight light-duty husker sheller, under corn ear size and the discrepant condition of work of humidity amplitude of variation, can make the damage of iblet reach bottom line.

The light-duty husker sheller scheme that addresses the above problem is: containing a support frame and in the lower end of this support frame one engine is being installed; and the engine belt pulley is by the triangle balata belt; connect be welded belt pulley on the power transmission shaft that tape spool holds of cylindrical tube two ends; and the bearing block of two bearings is welded in the upper end of support frame; and a Lower Half is arranged is that the concave grate and the first half are the threshing chamber of hood, and its rolling thrasher is by the six pieces short gear hobbings that are welded at the cylindrical tube outer surface; long gear hobbing and eight pieces of teeth of lying on one's side form two symmetrical five teeth of row and symmetrical four teeth of two rows and form radially being staggered arrangement and axially being evenly distributed structure in four pieces.

Light-duty husker sheller according to the such scheme manufacturing.Because simple in structure, rationally distributed, therefore the operation maintenance is easy to maintenance with transfer, and both practicable many scale threshing operations also can adapt to the separate unit working in dispersion.Under the low situation of threshing performance height, damage ratio, corncob remains intact, also effect is obvious for the iblet cleannes.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the light-duty husker sheller structure chart that the utility model proposes.

As shown in the figure, this thresher comprises a support frame 1 and by the manufacturing of angle steel material.The lower end of support frame 1 is equipped with an engine 2, and adopting power is that the single phase miniature motor of 550W or 1.5 horsepowers small-sized bavin (vapour) oil turbine are achieved.A belt pulley 3 is housed on engine 2 output shafts, and connect a cylindrical tube 24 two ends tape spool that is welded by triangle balata belt 4 and hold belt pulley 5 on the power transmission shafts 6 of 7,8 supportings, form with this and after one-level belt transmission is slowed down power is directly flowed to power transmission shaft 6.Long 330 millimeters of cylindrical tube 24 employings, diameter are 150 millimeters sheet steel pipe material, and two bearings 7,18 adopts the common rolling bearing of 1504 types.Bearing block 8,17 dresses of rigid bearing 7,18 are welded in the two side, upper end of support frame 1.Rolling thrasher 22 forms two symmetrical five teeth of row and symmetrical four teeth of two rows by long gear hobbing 23 in the six pieces short gear hobbings 25 of being welded at cylindrical tube 24 outer surfaces, four pieces and eight pieces of gear hobbings 15 of lying on one's side and forms radially being staggered arrangement and axially being evenly distributed structure.Gear hobbing 15,23,25 employing diameters are 22 millimeters round steel material manufacturing, short gear hobbing 25 ten millimeters of high 17 millimeters, middle long gear hobbing 23 Senior Two, 30 millimeters of gear hobbing 15 millimeters long of lying on one's side.The threshing chamber 16 of support frame 1 upper end is that the concave grate 21 and the first half are that hood 14 is welded and constitutes by Lower Half, and feed hopper 13, bottom that the top of threshing chamber 16 1 sides is provided with corn ear 12 are provided with the material-falling hopper 9 of iblet 10 and the tap 20 that the another side is provided with corncob 19.Concave grate 21 adopts the sheet metal material to make, and hood 14 adopts the manufacturing of common iron sheet material with feed hopper 13 and 9 of material-falling hoppers.When this machine adopted electromotor to be used as power, gross weight was about 38 kilograms.
