Abstract
The utility model relates to a straw discharging wheel for a combine harvester. The utility model is installed at the rear part of a threshing separating roller of the harvester, comprising a shaft, straw discharging gears and a straw discharging wheel body which are driven by power to be arranged on a machine frame through a bearing. The straw discharging wheel body is in the shape of a tube, and the straw discharging gears are arranged on the surface of the tube. The straw discharging wheel has the advantages of reasonable and simple structure, good using effect, etc. While used, the utility model can not generate air return to avoid direct damages to crops.
Description
The utility model relates to grass-removing wheel technical pattern in the threshing and separating device of combine harvester, is a kind of combine grass-removing wheel.
The grass-removing wheel of existing combine generally is positioned on the rear portion of the threshing cylinder of harvester threshing separator, is used for the crop after the threshing is discharged.Existing grass-removing wheel is generally open architecture and two kinds of forms of plank frame: wherein the open architecture grass-removing wheel is similar to existing roller frame form, has the opening of strip on its surface, is twined by the weeds after the threshing easily when Lysimachia sikokiana, influences its Lysimachia sikokiana efficient; The grass-removing wheel of another kind of plank frame is to adopt an entire plate, have on the both sides of plate and to grab careless tooth (Lysimachia sikokiana tooth), run up when carrying out Lysimachia sikokiana at it, the grass-removing wheel of plate like structure has return air, influence the threshing power of sheller unit, and outside the discharge machine that its Lysimachia sikokiana mode is a pile a pile, the crop loss is serious.
The utility model is to provide a kind of grass-removing wheel that Lysimachia sikokiana is effective, do not produce the barrel-type structure of return air in the Lysimachia sikokiana process that has at above-mentioned situation, is a kind of novel combine grass-removing wheel.
Grass-removing wheel of the present utility model is realized in the following manner: it is installed in the rear portion of harvester threshing separation barrel, includes by power drive and by the rack-mounted axle of bearing, Lysimachia sikokiana wheel body and Lysimachia sikokiana tooth; The Lysimachia sikokiana wheel body is cylinder-shaped, and the Lysimachia sikokiana tooth is distributed in the surface of cylindrical shell.
Characteristics such as grass-removing wheel of the present utility model has simple and reasonable, and result of use is good; When operation, do not produce return air, crop is not brought direct losses.
Below in conjunction with accompanying drawing technology contents of the present utility model and architectural feature thereof are further described:
Fig. 1 is the installation situation schematic diagram of grass-removing wheel;
Fig. 2 is the structural representation of grass-removing wheel of the present utility model;
Fig. 3 is that the P of Fig. 2 is to schematic diagram.
Referring to Fig. 1, Fig. 2 and Fig. 3, combine grass-removing wheel A of the present utility model is contained in harvester threshing separation barrel B rear portion, includes by power drive and by the rack-mounted axle 1 of bearing, Lysimachia sikokiana wheel body 2 and Lysimachia sikokiana tooth 3; Lysimachia sikokiana wheel body 2 is cylinder-shaped, and Lysimachia sikokiana tooth 3 is distributed in the surface of cylindrical shell.Described cylinder-shaped Lysimachia sikokiana wheel body is the cylindrical shell that general reference has tubular structure or similar tubular structure, as have cylindrical surface (supports support of its surface according to circumstances) and center Lysimachia sikokiana wheel shaft shape and structure, not explanation one by one to this by being connected with central shaft.
Above-mentioned cylinder-shaped Lysimachia sikokiana wheel body is the regular polygon body, and the Lysimachia sikokiana tooth is evenly distributed on each angle of regular polygon body.
Above-mentioned Lysimachia sikokiana wheel body is a cylinder, and the Lysimachia sikokiana tooth is evenly distributed on the surface of cylindrical shell.
Above-mentioned regular polygon body is square body or regular pentagon body or regular hexagon body, according to circumstances also can adopt other regular polygon body.
Above-mentioned Lysimachia sikokiana tooth top portion has a chamfering or the Lysimachia sikokiana tooth becomes an inclination angle to install with the cylindrical shell normal direction.Described Lysimachia sikokiana tooth is can be with cylindrical shell into a single integrated structure to be the outstanding drum surface of Lysimachia sikokiana tooth, also can adopt version such as welding to be installed in drum surface.
In order to guarantee the intensity of whole grass-removing wheel, according to circumstances can between cylinder inner surface and axle, be connected by reinforcement, the structure of relevant this respect and installation form do not elaborate at this for having general technology now.
The mounting structure of relevant grass-removing wheel (referring to accompanying drawing), this part structure is identical with the mounting structure of existing grass-removing wheel, can be referring to existing grass-removing wheel technology.
