Abstract
The utility model discloses a straw discharging wheel of a harvester, which comprises a plurality of straw discharging blades, a transmission shaft and anti-winding rings. The inner sides of the straw discharging blades are fixedly connected with the transmission shaft; two ends of the transmission shaft are supported on a harvester frame by bearings; one end of the transmission shaft is fixedly connected with a driving mechanism; the anti-winding rings are arranged at axial ends of the straw discharging blades and fixedly sleeved on the transmission shaft; the straw discharging blades include blades I and blades II; the inner sides of the blades I are fixedly connected with the transmission shaft; and the blades II arranged on the outer sides of the blades I are fixedly connected with the blades I by the aid of a plurality of fastening parts. The straw discharging wheel is simple in structure and convenient in assembly and disassembly. When the blades II of the straw discharging wheel are abraded severely, only the blades II need to be disassembled for replacement instead that the blades II together with the transmission shaft are replaced, so that the service cost of the straw discharging wheel is reduced greatly.
Description
Technical field
The utility model relates to a kind of grain header Lysimachia sikokiana device, and especially a kind of grain header grass-removing wheel belongs to agricultural machinery technological field.
Background technology
Grain header is realized effectively separating under the interaction of cereal threshing cylinder and intaglio plate in threshing system in operation process, and the crop cane is discharged body by grass-removing wheel simultaneously.Grass-removing wheel generally is installed in harvester threshing cylinder rear portion, and grass-removing wheel blade front end weares and teares easily, and then influences Lysimachia sikokiana efficient and Lysimachia sikokiana effect, needs often it to be changed.Because existing grain header grass-removing wheel blade and power transmission shaft are the integral solder structure, when changing the grass-removing wheel blade, must change together with power transmission shaft, cause very big waste, have improved replacement cost greatly, and in the replacing process, dismounting is also very difficult.
The utility model content
The purpose of this utility model provide a kind of simple in structure, replacement cost is low, the grain header grass-removing wheel of easy accessibility.
The utility model is achieved by the following technical programs:
A kind of grain header grass-removing wheel, comprise several Lysimachia sikokiana blades, power transmission shaft, the anti-circle that twines, described Lysimachia sikokiana blade is inboard fixedlys connected with power transmission shaft, described power transmission shaft two ends by bearings on the grain header frame, fixedly connected with driving mechanism in power transmission shaft one end termination, the described anti-circle that twines is arranged on described Lysimachia sikokiana sharf to two ends, is fixedly set on the described power transmission shaft; Described Lysimachia sikokiana blade comprises blade I, blade II, and described blade I is inboard fixedlys connected with power transmission shaft, and described blade II is arranged on the blade I outside, fixedlys connected with the blade I by several securing members.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid grain header grass-removing wheel, wherein said blade I, blade II are L shaped structure, and the minor face of blade I, blade II leans on mutually, and is fixedly connected by securing member.
The utility model is simple in structure, the grass-removing wheel blade is made up of the blade I of inboard, the blade II two parts in the outside, owing to have only blade II front end to wear and tear easily in the Lysimachia sikokiana process, only need pull down securing member takes off replacing with the blade II and gets final product, and needn't change together with power transmission shaft, greatly reduce use cost, and dismounting is very convenient.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises 2 with the symmetrically arranged Lysimachia sikokiana blade 1 in power transmission shaft 2 centers, power transmission shaft 2, the anti-circle 3 that twines, Lysimachia sikokiana blade 1 is inboard fixing with power transmission shaft 2 welding, power transmission shaft 2 two ends by bearings on bearing block 4, bearing block 4 is fixedlyed connected with the grain header frame, fixedlys connected with driving mechanism 5 in power transmission shaft 2 one end terminations, and the anti-circle 3 that twines is arranged on Lysimachia sikokiana blade 1 axial two ends, be fixedly set on the power transmission shaft 2, the crop cane is wrapped on the power transmission shaft 2 when preventing Lysimachia sikokiana.Lysimachia sikokiana blade 1 comprises blade I 11, blade II 12, and blade I 11 inboards are welded into overall structure with power transmission shaft 2, and blade II 12 is arranged on blade I 11 outsides.Blade I 11, blade II 12 are L shaped structure, and the two minor face leans on mutually, and is fixedly connected by securing member.Also be respectively equipped with stiffener I 6, stiffener II 7 on blade I 11, the blade II 12, can strengthen the working strength of blade I 11, blade II 12.After 1 wearing and tearing of grass-removing wheel blade, only need pull down securing member, blade II 12 is taken off replacing get final product, easy accessibility has been saved cost greatly.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
