Description
Technical field
The present invention relates to parts on a kind of grain header, particularly protective device is blocked in a kind of ceding of Taiwan.
Background technology
Northern China most area summer crop is based on corn planting, but the mechanization degree of reaping corn is still lower so far, along with 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 when gathering in cannot normally can work because of blocking, and once not react in time when there is this kind of situation, very easily damage parts because power does not cut off, thus further increase use cost, have a strong impact on harvesting efficiency and the economy of corn picker.
In order to the obstructing problem that may occur when solving corn picker harvesting, market there is a kind of jaw clutch protective device.Its innovative point is, the basis of original corn picker adds this arrangement of clutch.Grain header operationally, under normal condition two of castellated arrangement of clutch engagement gear rings power (spring force) outside effect under normally engage, power transmits smoothly.Once there is the phenomenon of blocking, instantaneously a moment of torsion along direction of rotation can be produced between two engagement gear rings, started to overcome spring force slippage backward by the engagement gear ring of spring action under this effect, it engages with another between gear ring and produces relative sliding fast simultaneously, and sends noise to report to the police.Personnel recognize after obstruction can parking maintenance calmly.This device ensure that the ceding of Taiwan is when blocking generation, and the kinetic force passed over from fuselage disconnects with header transmission system fast, and the situation avoiding the damage parts caused because power does not cut off in time occurs, and has obviously advanced.
Although the application of above-mentioned arrangement of clutch achieves the protection of ceding of Taiwan obstruction, improves the requirement of the safety of corn picker; but create 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; larger space will certainly be taken laterally; and this segment space is unnecessary for other drive disk assemblies, also may have influence on the determination of complete machine fabric width simultaneously.In addition, need larger sprocket wheel as output, otherwise transmission position and space will be redesigned, general configuration in conjunction with the ceding of Taiwan of the corn picker on market is analyzed known, need multi-stage speed-reducing just can reach job requirement during its work, if use hinge wheel output, this can produce certain restriction to design.
Summary of the invention
The object of this invention is to provide a kind of structure simple, protective device is blocked in the ceding of Taiwan that space occupancy rate is little.
The technical scheme realizing the object of the invention is: the present invention includes ceding of Taiwan power transmission shaft, is assemblied in the sprocket wheel on ceding of Taiwan power transmission shaft and arrangement of clutch; 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 to have one end of engaging tooth to engage with the right gear ring that engages, left engagement gear ring does not have one end of engaging tooth and sprocket wheel to be fixedly connected into an entirety and can dally on ceding of Taiwan power transmission shaft, 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 with the axis being parallel of ceding of Taiwan power transmission shaft; Described baffle plate to be fixedly installed on ceding of Taiwan power transmission shaft and to be positioned on the right side of case, 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 present invention has positive effect: (1) the present invention simplify more compared to traditional clutch configuration; (2) arrangement of clutch is set to stage casing by the present invention, and space occupancy rate is little; (3) the present invention changes original flat key transmission into spline drived, adds reliability and flexibility ratio; (4) arrangement of clutch is protected by case by the present invention, adds safety.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, the present invention includes ceding of Taiwan power transmission shaft 1, be assemblied in the sprocket wheel 2 on ceding of Taiwan power transmission shaft 1 and arrangement of clutch; 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 to have one end of engaging tooth to engage with the right gear ring 4 that engages, and left engagement gear ring 3 does not have one end of engaging tooth and sprocket wheel 2 to be fixedly connected into an entirety and can dally on ceding of Taiwan power transmission shaft 1; 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 the bottom of one end of engaging tooth and 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 7 with the axis being parallel of ceding of Taiwan power transmission shaft 1; Described baffle plate 8 to be fixedly installed on ceding of Taiwan power transmission shaft 1 and to be 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.
In normal state, due to the effect of spring 5, left engagement gear ring 3 engages gear ring 4 engaged transmission with right; 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 right engagement gear ring 4 to produce a very large torsion force right engagement gear ring 4 to overcome the active force of spring 5 with left engagement between gear ring 3, right engagement gear ring 4 is formed be separated-engage-recurrent state that is separated again with left engagement gear ring 3, simultaneously because producing rigid collision sound between engaging tooth to reach the object of warning.
