Description
Technical field
The utility model relates to parts on a kind of grain header, and particularly protective device is blocked in a kind of ceding of Taiwan.
Background technology
Northern China most areas summer crop be take corn planting as main, but the mechanization degree of reaping corn is still lower so far, be accompanied by the develop rapidly of the mechanization degree of modern agriculture, a kind of corn picker of high speed high reliability has its huge market demand undoubtedly.
But due to the planting patterns of corn and the reason of region, corn picker ceding of Taiwan meeting when harvesting cannot normally be worked because block, once and not react in time while there is this kind of situation, very easily because not cutting off, damages power parts, thereby further increased use cost, had a strong impact on harvesting efficiency and the economy of corn picker.
In order to solve the obstructing problem that may occur when corn picker gathers in, on market, there is a kind of castellated clutch protective device.Its innovative point is, has increased this arrangement of clutch on the basis of original corn picker.Grain header is in when work, normally engagement under the effect of power (spring force) outside of two of castellated arrangement of clutch engagement gear rings under normal condition, and power transmits smoothly.Once there is the phenomenon of blocking, between two engagement gear rings, instantaneous meeting produces a moment of torsion along direction of rotation, under this effect, by the engagement gear ring of spring action, started to overcome spring force slippage backward, simultaneously it with another engagement gear ring between produce relative sliding fast, and send noise with warning.Personnel recognize after obstruction parking maintenance calmly.This device has guaranteed that the ceding of Taiwan is when block occurring, and the kinetic force passing over from fuselage disconnects with header transmission system fast, has avoided the situation of the damage parts that causes because power does not cut off in time to occur, and has very significantly advance.
Although the requirement that the application of above-mentioned arrangement of clutch has realized the protection that the ceding of Taiwan is blocked, improved the safety of corn picker; but produced again new problem; because this mechanical mechanism takes up room larger; if be placed on the axial end portion of ceding of Taiwan power transmission shaft; will certainly take laterally larger space; and this segment space is unnecessary for other drive disk assemblies, also may have influence on determining of complete machine fabric width simultaneously.In addition, need larger sprocket wheel as output, otherwise will redesign transmission position and space, general configuration in conjunction with the ceding of Taiwan of the corn picker on market is analyzed known, during its work, need multi-stage speed-reducing just can reach job requirement, if use hinge wheel output, this can produce certain restriction to design.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, and protective device is blocked in the ceding of Taiwan that space hold rate is little.
The technical scheme that realizes the utility model object is: the utility model comprises ceding of Taiwan power transmission shaft, is assemblied in sprocket wheel and arrangement of clutch on ceding of Taiwan power transmission shaft; Described arrangement of clutch comprises left engagement gear ring, right engagement gear ring, spring and spring base; Described arrangement of clutch and sprocket wheel are all arranged on the stage casing of ceding of Taiwan power transmission shaft; Described left engagement gear ring, right engagement gear ring and spring housing are contained on ceding of Taiwan power transmission shaft; Described left engagement gear ring has one end of engaging tooth and the engagement of one end that right engagement gear ring has engaging tooth, left engagement gear ring does not have one end of engaging tooth and sprocket wheel are fixedly connected into an integral body and can on ceding of Taiwan power transmission shaft, dally, and right engagement gear ring does not have one end of engaging tooth and be fixedly installed between the spring base on ceding of Taiwan power transmission shaft to be provided with spring; The center of described right engagement gear ring is provided with keyway and coordinates with the key transmission on ceding of Taiwan power transmission shaft.
Above-mentioned spring base comprises case, guide rod and baffle plate; Described right engagement gear ring does not have to be provided with spring between one end of engaging tooth and the bottom of case, and case is located at the outside of spring, and the bottom of case is provided with the guide rod parallel with the axis of ceding of Taiwan power transmission shaft; Described baffle plate is fixedly installed on ceding of Taiwan power transmission shaft and is positioned at case right side, and baffle plate is provided with the hole corresponding with guide rod.
The center of above-mentioned right engagement gear ring is spline and is connected with the spline fitted on ceding of Taiwan power transmission shaft.
The utlity model has positive effect: (1) the utility model is simplified more than traditional clutch configuration; (2) the utility model is set to stage casing by arrangement of clutch, and space hold rate is little; (3) the utility model changes original flat key transmission into spline drived, has increased reliability and flexibility ratio; (4) the utility model protects arrangement of clutch by case, has increased safety.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utility model comprises ceding of Taiwan power transmission shaft 1, is assemblied in sprocket wheel 2 and arrangement of clutch on ceding of Taiwan power transmission shaft 1; Described arrangement of clutch comprises left engagement gear ring 3, right engagement gear ring 4, spring 5 and spring base; Described arrangement of clutch and sprocket wheel 2 are all arranged on the stage casing of ceding of Taiwan power transmission shaft 1; Described left engagement gear ring 3, right engagement gear ring 4 and spring 5 are sleeved on ceding of Taiwan power transmission shaft 1; Described left engagement gear ring 3 has one end of engaging tooth and the engagement of one end that right engagement gear ring 4 has engaging tooth, and left engagement gear ring 3 does not have one end of engaging tooth and sprocket wheel 2 are fixedly connected into an integral body and can on ceding of Taiwan power transmission shaft 1, dally; Described spring base comprises case 6, guide rod 7 and baffle plate 8; Described right engagement gear ring 4 does not have to be provided with spring 5 between one end of engaging tooth and the bottom of case 6, and case 6 is located at the outside of spring 5, and the bottom of case 6 is provided with the guide rod parallel with the axis of ceding of Taiwan power transmission shaft 17; Described baffle plate 8 is fixedly installed on ceding of Taiwan power transmission shaft 1 and is positioned at the right side of case 6, and baffle plate 8 is provided with the hole corresponding with guide rod 7; The center of described right engagement gear ring 4 is spline and is connected with the spline fitted on ceding of Taiwan power transmission shaft 1.
Under normal condition, due to the effect of spring 5, left engagement gear ring 3 and right engagement gear ring 4 engaged transmission; When the ceding of Taiwan is blocked, ceding of Taiwan power transmission shaft 1 and right engagement gear ring 4 stop the rotation, but sprocket wheel 2 and left engagement gear ring 3 are still rotated further around ceding of Taiwan power transmission shaft 1 under the effect of power, now between right engagement gear ring 4 and left engagement gear ring 3, can produce a very large torsion forces right engagement gear ring 4 to overcome the active force of spring 5, make right engagement gear ring 4 and left engagement gear ring 3 form the separated recurrent state of separated-engagement-again, simultaneously because producing rigid collision sound between engaging tooth to reach the object of warning.
