Abstract

The utility model relates to a corn thresher, which comprises a frame 8, a motor 13 and a roller chamber, wherein the roller chamber consists of an upper cover 2 and a bottom bracket 3. A threshing roller 18 is arranged in the roller chamber. A material inlet 1, a trash exhaust opening 5 and a pith exhaust opening 7 are arranged on the roller chamber. A material outlet 11 is arranged on the lowerpart of a screen 12 at the bottom of the roller chamber. The corn thresher is characterized in that rotary teeth 17 are arranged on the threshing roller of the material inlet; conical teeth 19 are arranged in the middle of a shaft roller; and the tail part of the shaft roller is provided with inclined teeth 21 and plane teeth 20. As the threshing roller is provided with a plurality of stages of tooth plates, the tooth distance between rotary teeth and the angles formed by the rotary teeth and the shaft roller are reasonable in design, and the rotary teeth have guide function on corn cobs and can be matched with the conical teeth, the inclined teeth and the plane teeth on the threshing roller to thresh different dry and wet corn cobs, and also thresh sorghum, soybean, grain, wheat and the like. The utility model has the advantages of high threshing efficiency, no trash of grains, no crashing core, no material blockage, convenient operation, high working efficiency, and flexible movementin various operation fields.

Description

Husker sheller

Technical field

The utility model relates to a kind of husker sheller, makes the chip-proof husker sheller of corncob during particularly a kind of threshing.

Background technology

Existing husker sheller is made up of frame, stripping grain cylinder, roller chamber, sieve plate, charging aperture, discharging opening, drive motors and driving member usually.200620032341.8 number patent; the not broken core husker sheller of a kind of winnowing type self-regulated is disclosed; comprise frame, threshing bin, threshing cylinder, motor, charging aperture, discharging opening; the bottom of threshing cylinder also is provided with the major and minor threshing castor that flexibly connects with frame around its position, both sides, front and back; and be concentric circles with threshing cylinder and cooperate and form corn rod threshing operation passage, be equipped with the regulating spring that can adjust distance between threshing castor and the threshing cylinder automatically at two threshing castors and frame connecting portion.Adopt the husker sheller of said structure mainly to have the following disadvantages: though the corn ear passage between 1 threshing cylinder carries out automatic Compensation Regulation by regulating spring, make this threshing function adapt to the threshing operations of different big or small corn ear at any time, but the secondary threshing castor of spacing whole dependence of corncob, corncob easily in threshing bin around the threshing cylinder threshing of repeatedly overturning, cause the broken grain quality that influences of corncob; Need bigger extruding force during 2, owing to threshing, behind the employing regulating spring, exist extruding force to cause the unclean problem of threshing inadequately; 3, can only carry out threshing to dried corn, increase the input of human and material resources; 4, once can only carry out threshing,, have the problem that gets stuck if when once dropping into more corn ear to less corn ear; 5, machine volume big energy-consuming, inconvenience is moved.

Summary of the invention

The utility model purpose is to overcome the above problem that existing husker sheller exists, and designs a kind of not broken core, through threshing and grain no-sundries, does not get stuck, the husker sheller of energy and labour saving.

For achieving the above object, the technical scheme taked of the utility model is:

A kind of husker sheller; the roller chamber that comprises framework [8], motor [13], forms by loam cake [2] and underframe [3]; the indoor grain threshing roller [18] that is provided with of roller; the roller chamber is provided with charging aperture [1], impurity discharging port [5], arranges taste [7]; the screen cloth [12] of bottom, roller chamber has discharging opening [11]; it is characterized in that being positioned at being equipped with on the grain threshing roller [18] at charging aperture place and revolve tooth [17], awl tooth [19] is equipped with at the beaming roller middle part, and the beaming roller afterbody is equipped with inclined-plane tooth [21] and flat tooth [20].

For guaranteeing the disconnected rod of not broken core, improve the threshing quality, in elementary threshing course, the tooth pitch and the corn ear diameter that revolve on the grain threshing roller [18] between the tooth [17] adapt, the direct of travel and the beaming roller angulation that revolve tooth are 20～30 °, charging aperture [1] position is fixed on the roll shaft inner face blade [16], forms high velocity air by the driven by motor fan blade various foreign material in the iblet that breaks away from are separated eliminating.Folding shaft [9] is housed on framework [8] both sides lower carriages [14], and side lower carriage [14] bottom dress moves wheel [10], is convenient to the folding upward back of support and moves.

The utlity model has following advantage:

1, because multistage tooth plate is housed on grain threshing roller, make corncob directly run to the knockout mouth along the operation passage, can in threshing bin, repeatedly not overturn around threshing cylinder, protect the complete of corncob, the purpose of broken core not when reaching threshing and separating, once can carry out threshing, and not have the problem that gets stuck a plurality of corn ear;

2, in elementary threshing course, grain threshing roller revolves tooth pitch between the tooth, revolve tooth and the beaming roller angulation is reasonable in design, to the existing guide effect of corn ear, can also cooperate with awl tooth, the helical teeth peace tooth on the thrashing roller, carry out threshing to the doing of different sizes, wet corn are excellent, the threshing performance height per hour can go out threshing corn more than 1200 kilograms, also can carry out threshing to Chinese sorghum, soybean, millet wheat etc. simultaneously;

3, form high velocity air by the driven by motor fan blade the various foreign material in the iblet that breaks away from are separated eliminating, through threshing and grain no-sundries, easy to operate, high efficiency can move flexibly in various operations place.
