Abstract

The utility model provides a corn thresher. A support seat and a hopper, a top cover, a material falling baffle and a back baffle thereof are supported by a machine frame. A threshing licker-in is matched with a bottom net sieve and two slices of arc rib plates which are arranged on the inside of the top cover. Outer power is transmitted by a pulley to complete the threshing of the corns and the continuous discharge of a core bar. The utility model, having the advantages of simple structure and low manufacture cost, has broad application to the corn threshing in the farm for the farmer. More than 3500 kg corns can be threshed per hour, and the threshing rate is bigger than 99.5%.

Description

Corn thresher

The utility model relates to a kind of mechanical type thresher, exactly belongs to a kind of husker sheller.

Existing husker sheller is mainly manual or two kinds of mechanical electrodynamic types; hand threshing machine only can be used for threshing in a small amount; it is time-consuming to require great effort; and mechanical type thresher threshing efficiency is not high; purify rate variance, and the plug badly broken after taking off, broken rod mixes with iblet not to be allowed to separate; influence the threshing quality, and complex structure, cost of manufacture height.

The purpose of this utility model is to design a kind of render meritorious service rate height that takes off, and threshing performance height, plug are not breakable, and be simple in structure, the husker sheller that cost is low.

The purpose of this utility model realizes in the following way, husker sheller is made up of frame (1) and semicircle tubbiness top cover (4) and left and right sides bearing (12,6), and it is characterized in that being supported on bearing (12) is to be equidistant installation and to be 20-50 ° of right-hand screw lift angle with the axle center with respect to the perverse roller of threshing (7) axle center near bearing (6) one sides with the perverse roller of thresher (7) on (6) with two that are fixed on top cover (4) inboard, top parallel arcuation gussets (5); The semi-cylindrical screen cloth (9) that is positioned at the perverse roller of threshing (7) bottom is installed with it with one heart.

The perverse roller of threshing of the present utility model (7) is the hollow axle of wearing, and its surface is provided with to be revolves the halfpace shape tooth that direction is interrupted arrangement, and the branch's arrangement vertically of each tooth.

The crescent that the bearing block upside of bearing of the present utility model (6) is provided with horizontal shape back-off goes out excellent core hole.

Spacer screen sieve of the present utility model (9) can be the semicircle tubbiness or cross section is that half of gear end is planar.

Advantage of the present utility model is to carry out corn threshing efficiently, and the plug breakage rate is low and can continuously plug be discharged outside the machine, and threshing performance reaches 99.8%, per hour can take off more than the iblet 3500kg, improves the threshing quality, reduces labor intensity.

Now further describe manufacturing process of the present utility model in conjunction with the accompanying drawings:

Accompanying drawing 1 is the front view of husker sheller; Accompanying drawing 2 is rearviews of husker sheller.

Among the figure: 1 frame, 2 belt pulleys, 3 hoppers, 4 top covers, 5 arcuation gussets, 6 bearings, the perverse roller of 7 threshings, 8 bearing blocks, 9 spacer screens sieve, 10 blanking plate washers, 11 back plate washers, 12 bearings.

Frame shown in the figure (1) is welded by angle steel, belt pulley is processed by cast iron, bearing (12) and (6) that both sides are installed on frame (1) both sides are formed by casting: and be processed with bearings mounted hole, and by bearing supporting be installed with belt pulley (2) and the perverse roller of threshing (7) the axle, the axle upside is equipped with semicircle tubbiness top shape top cover (4), top cover (4) one face down bondings are connected to hopper (3), the arcuation gusset (5) of two parallel installations of row's plug guide effect is installed in the opposite side inside top, it is installed with one heart with respect to threshing licker-in (7) axle center and is 30 ° of right-hand screw lift angles with the axle center, be positioned at a bottom concentric with it semicircle tubbiness spacer screen sieve (9) is installed, threshing licker-in (7) surface is provided with the tooth that is the halfpace shape, and embark on journey vertically and be arranged in parallel, each tooth is dextrorotation again and is interrupted the shape arrangement along the roller surface, it can or be welded by casting.

Bearing of the present utility model (6) and (12) are the semicircle laminated structures, form through casting, and bearing (6) are cast with the crescent moon shape that is the traverse back-off on its dead eye top and go out excellent core hole.Connect top cover (4) one side front ends on its blanking plate washer (10), the meet sb. at the airport frame cross tie of frame rear side of the other end, and containing spacer screen sieve (9), iblet guiding after the processing is flowed out, at frame rear side first line of a couplet top cover (4) and be fixed on the back plate washer (11) that has to be separated by and to leave discharging opening with stull at the bottom of the frame on the frame, baffle plate and hopper all roll with steel plate boring and form with the steel plate spacer screen sieve that is welded.

Present embodiment appearance and size is:

Length * height * wide: 710 * 410 * 700(mm)

Spindle revolutions; 1000rpm

Production efficiency:＞3500 kilograms/hour

Threshing performance:＞99.5%

Be equipped with power: 7.5KW or 195 diesel engines.
