Description
Technical field
The utility model relates to the farm machinery technical field, exactly relates to a kind of husker sheller.
Background technology
Existing husker sheller is divided into two kinds of threshing structures substantially, and a kind of is the structure that makes the threshing of corn ear cross-feed, and a kind of is the structure that makes the threshing of corn ear longitudinal feeding.
The structure of cross-feed threshing; as Granted publication number is CN2525783; Granted publication day is that the Chinese utility model patent file on December 18th, 2002 discloses a kind of husker sheller; the threshing bin that is connected with frame is provided with the charging aperture of corn ear; the knockout mouth of the grain export of iblet and corncob; be provided with in the threshing bin along outer circumference surface and be provided with granule-stripping reinforcement tooth and can be by the threshing roller structure of actuating unit driven in rotation; its below is provided with the mesh structure that a core separates through maintaining the operation passage that allows corncob to pass through, and its below is connected with grain export.Radial width of its operation passage between corn ear external diameter and corncob external diameter, and in the corn ear porch of operation passage through and feed material blocking structure be equipped with can with the threshing blocking platform structure of granule-stripping reinforcement tooth cooperating on the threshing roller structure.Thresher of the present utility model can not only have can be to fresh broad applicability of carrying out threshing with corn drying, and can solve the broken core problem in the threshing course well.But the husker sheller of this structure; its charging aperture can only allow laterally charging threshing one by one of corn ear; can not realize many corn ear charging simultaneously threshing; the speed of threshing is lower like this; and because the operation channel sized of threshing tube is relatively-stationary, for rod footpath corn ear not of uniform size, threshing performance is lower; also can there be the excessive situation of percentage of damage simultaneously, or corn ear is broken.
And can not solve the technical problem that rod footpath corn ear not of uniform size can threshing at the cross-feed threshing structure; having occurred with Granted publication subsequently again number is CN 201088034; Granted publication day is the technology that the Chinese utility model patent file on July 23rd, 2008 is representative; this patent document discloses a kind of wide applicability small-sized corn thresher; belong to a kind of crops sheller unit; be by frame; power; power transmission; collection grain case; bearing block; hood; feed hopper and threshing cylinder; threshing board; the elastic top materials device; plug discharging collection grain device constitutes; it is wide to have applicability; input and output material is unobstructed; characteristics such as threshing efficiency height; can adapt to the threshing of the corn ear of all size; and through threshing; corn kernel is difficult for splashing, and is a kind of practical wide small-sized corn thresher of applicability.Though this husker sheller has solved the threshing of problem all can carry out to(for) rod footpath corn ear not of uniform size, still can not realize bulk-fed and discharging, threshing speed is also unhappy certainly, and threshing performance is also undesirable.
For this reason, the structure of corn ear longitudinal feeding threshing has appearred making on the market, this kind structure has solved the technical problem that makes the bulk-fed and discharging of corn ear substantially, threshing speed is significantly accelerated, as application publication number is CN101731066A, Shen Qing Publication day is that the Chinese invention patent Shen Qing Publication file on June 16th, 2010 discloses a kind of husker sheller, comprise feed hopper, sheller unit and support, feed hopper is installed on sheller unit top, sheller unit is fixed on the support, the sheller unit lower end is provided with discharging opening, sheller unit is by the threshing tube, pressing plate and baffle plate constitute, and it is curved that pressing plate is positioned at threshing tube top, and baffle plate is positioned at the side of threshing tube and pressing plate, the threshing tube, form the arc threshing bin between pressing plate and the baffle plate, the entrance point bore of threshing bin is greater than port of export bore; Described threshing tube is provided with threshing muscle or threshing tooth, and the bottom of threshing tube is provided with protective case; Described pressing plate is made of pressing plate, pressure pipe, press strip, stage clip, and the top of pressing plate is provided with elastic device; This invention has solved the different corn ear charging in big spillikin footpath and the problem of threshing, and can bulk-fed and threshing, and the threshing effect is very good, and threshing speed is very fast, and threshing performance almost can reach 100%, structure tube list, and production cost and use cost are all lower.But this structure is in actual application, the threshing amount is big inadequately, only can satisfy the demand of southern areas such as Sichuan, requiring in threshing amounts such as the north then can't be suitable fully than higher area, strengthen under the situation of threshing amount even be suitable for reluctantly, its threshing performance just obviously reduces again, thereby needs to repeat threshing, waste the time, improved production cost.
