Abstract

The utility model belongs to a threshing machine in the field of agricultural machinery, and discloses a corn thresher which comprises a feeding hopper, a drum shaft, a concave plate screen, an upper machine shell, a vibrating screen and a machine frame, wherein the feeding hopper is located on the upper left side of the upper machine shell, the drum shaft is mounted on the machine frame, threshing push-in teeth are arranged on the left of the drum shaft, threshing push-out teeth are arranged on the right of the drum shaft, and threaded straight teeth are arranged in the middle of the drum shaft. The upper machine shell is arranged above the drum shaft, the concave plate screen is arranged under the drum shaft, the vibrating screen is located on the upper right side of the upper machine shell, and an inlet of the vibrating screen is connected with a corn cob discharge opening in a butt joint mode. The corn thresher solves the problems that an existing axial flow type corn thresher is low in threshing rate and high in crashed rate, threshing rate of the corn thresher reaches more than 99.5 percent, and crashed rate of the corn thresher is only 0.5 percent. The corn thresher is simple in structure, convenient to adjust, and capable of threshing dry corns, wet corns and corns varied in size.

Description

Husker sheller
Technical field
The utility model belongs to the thresher machine in the agricultural mechanical field.
Background technology
At present, the axial-flow type husker sheller that uses in the rural area, it is low that great majority exist threshing performance, the shortcoming that percentage of damage is high.The reason that threshing performance is low: the one, the upper casing inwall does not have sheller unit, and corn ear is slided and mistake on its surface one during threshing, and such upper casing does not have the threshing function substantially; The 2nd, at the row of the husker sheller rod mouth row of setting rod speed control device not, can not control the interior pressure of threshing chamber, just can not control threshing performance.Threshing performance is low, needs during threshing manually to pick up specially the corn ear that does not purify, and in today that labor wage improves constantly, does not calculate very much.The reason that percentage of damage is high: be at the first threshing chamber, what adopt is the straight-tooth that head has corner angle, and the skin of corn ear is iblet entirely, and what the direct strike of corner angle straight-tooth was arranged is iblet, iblet will be scratched or be broken, and broken iblet is broken at the first threshing chamber more than 90%.
Summary of the invention
The purpose of this utility model provides a kind of husker sheller, and this husker sheller threshing performance is up to more than 99.5%, and percentage of damage drops to below 0.5%, but the dried corn of threshing, wet corn, the corn that varies in size.
The design that its technical problem that solves the utility model adopts is: comprise that drum shaft, U-shaped threshing advance tooth, screw thread straight-tooth, threshing to release tooth, upper casing, threshing bar, vibratory sieve, it is characterized in that: the drum shaft left side is welded U-shaped threshing and is advanced tooth, the right welding threshing to release tooth, middle welding screw thread straight-tooth; Some threshing bars of upper casing inwall welding; Vibratory sieve and mouthful docking of row's rod.
Described U-shaped threshing advances tooth to be welded on sideling the drum shaft left side, and gradient is between 20 °~80 °.
Described threshing is released tooth and is welded on sideling drum shaft the right, and gradient is between 20 °~80 °.
Since adopted upper technical scheme, the utility model beneficial effect be threshing performance up to more than 99.5%, percentage of damage drops to below 0.5%, but the dried corn of threshing, wet corn, the corn that varies in size.
Description of drawings
Fig. 1 is the structural representation of the husker sheller that provides of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Description of reference numerals: the threshing of 1U type advances tooth, 2 first threshing chambers, 3 drum shafts, 4 second threshing chambers, 5 screw thread straight-tooth, 6 upper casings, 7 threshings to release tooth, 8 row's rod mouths, 9 vibratory sieves, 10 feeding hoppers, 11 frames, 12 iblet outlets, 13 threshing bars, 14 concave grates, 15 screw feeder conveying axis, 16 lower casings.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
As shown in the figure, drum shaft 3 is installed on the frame 11, and the left side is that U-shaped threshing advances tooth 1, is welded on sideling drum shaft 3 left sides, and gradient between 20 °~80 °, is distributed in the first threshing chamber 2 greatly; The top of the first threshing chamber 2 is spouts, is screw thread straight-tooth 5 in the middle of the drum shaft 3, and the right is that tooth 7 is released in threshing, is welded on sideling drum shaft 3 the right, and gradient is greatly between 20 °~80 °; The top of drum shaft 3 is the upper casings 6 that are welded with the threshing bar, and the below is concave grate 14, and feeding hopper 10 is positioned at the upper left side of upper casing 6, is connected with upper casing 6; Vibratory sieve 9 is positioned at row's rod mouthful 8 places, mouthful 8 docking of entrance and row's rod; The below of thresher is screw feeder conveying axis 15, and the lower right is iblet outlet 12.
After corn ear entered the first threshing chamber 2 from feeding hopper 10, what at first run into was that U-shaped threshing advances tooth 1, and U-shaped threshing advances the thick round steel brake forming of tooth 1 usefulness, and the edge is smoother not to have corner angle, and it can not scratch corn, to the damage minimum of iblet; At the first threshing chamber 2, iblet can be taken off more than 70%; It is to be welded on sideling on the drum shaft 3 that U-shaped threshing advances tooth 1, and it rotates just stable propulsive force, and the corn ear that it will not purify is shifted the second threshing chamber 4 onto.The top of the second threshing chamber 4 is the circular strip threshing bars 13 that radially weld, the below is the rough concave grate 15 that is woven into round wire, screw thread straight-tooth 5 threshing efficiencies are very high, although corner angle are arranged, but what it touched is the corncob of threshing more than 70%, the corncob top layer is soft, and at the second threshing chamber 4, the damage that iblet is subject to is very little.Corn ear is under the quick rotation of screw thread straight-tooth 5, and with the 13 mutually mutual friction of concave grate 15 of threshing bar, mutually collision is in the fully threshing of the second threshing chamber quilt.Row's rod mouth 8 is equipped with the vibratory sieve 9 of adjustable amplitude, and the large row's rod speed of amplitude is just fast, and threshing performance just reduces, amplitude float rod speed is just slow, and threshing performance is just high, appropriate regulation vibratory sieve 9 amplitudes size, just can effectively control the height of threshing performance, just can bring up to threshing performance more than 99.5%.Described screw thread straight-tooth is distributed in the second threshing chamber, and the top of the second threshing chamber is the upper casing that has welded the threshing bar, and the below is the concave grate with circular thicker wire braiding.
