A kind of loading machine lateral unloading device
Technical field
The present invention relates to technical field of engineering machinery, more particularly to a kind of loading machine lateral unloading device.
Background technique
Major function equipment of the loading machine as development & construction such as civil construction, coal mine, iron ores, effect is self-evident,
It, which is equipped with different accessory link mechanisms, can complete some special functional demands.Wherein coal mining, the operating conditions such as tunnel construction
Since working space is narrow, loading machine can only be moved forward and backward, and to complete to shovel loading and unloading operation, side-discharging device comes into being.And mesh
The preceding side dumping used in the market is all the front and back overturning and left and right overturning all crossed articulated structure and realize scraper bowl.Its construction profile figure is such as
Shown in Fig. 1-2.When existing side-discharging device shovel dress, by taking the right side is unloaded as an example, a left side is unloaded hinged (scraper bowl and bracket) and is overlapped;It unloads hingedly on the right side
The merga pass pin shaft connection of (scraper bowl and bracket) weight.
Scraper bowl 1 receives bucket after shoveling material, and pull rod pulls bracket 2 by pull rod hinged-support 6, makes scraper bowl around swing arm hinged-support
5 rotations are completed to receive bucket movement.Bracket unloads hinged-support 4 by the right side and transmits torque to scraper bowl during this.Weight, which is given rise to, to be unloaded
After carrying height, scraper bowl unloads hinged-support rotation around the right side and completes discharging.Plane where A indicates scraper bowl mass center in Fig. 2 (and connecting rod machine
Structure transmits torque ideal plane), when B indicates tipping bucket, where the position of comprehensive function power (material reaction and scraper bowl gravity)
Plane.In real work, comprehensive function point of force application can not be located at B, and extreme case is located at A left side of face.When bucket is received in analysis,
It is as shown in Figure 3 relative to 7 stress condition of pin shaft on comprehensive function power horizontal plane.F is comprehensive function power, and F1 is scraper bowl left and right directions
Component, F2 scraper bowl front and back component.Therefore, pin shaft both direction all bending moments (shearing force), and with comprehensive function point in work
Variation, moment of flexure size constantly changes.
It is not overlapped due to transmitting torque ideal plane A in link mechanism with plane B, driving device drives loading machine right
Torque transmission efficiency when unloading is low.And since the face A is not overlapped with the face B, the right side unloads that unload hinged place stress condition with a left side complicated, is also easy to produce
Fracture.If the right side is unloaded hinged place and is plastically deformed, a scraper bowl left side, which is unloaded, hingedly unloads hinged dislocation with a bracket left side, can make scraper bowl that can not return
Position.Scraper bowl unloads hinged rotation around the right side, and the face scraper bowl right hand edge distance A is more and more closer, therefore unloads distance and shovel no more than original state
Struggle against edge.

Compared with prior art, the beneficial effects of the present invention are:
1) present invention substituted using arc sliding portion and arc-shaped guide rail cooperation pin shaft it is hinged by the way of, the self weight of scraper bowl with
And the gravity of material is shared by entire arc-shaped guide rail and arc sliding portion, effective contact area is bigger, unit in torque transmitting
Pressure is small, when can be to avoid using single pin shaft, pin shaft repeatedly stress easily-deformable fracture the shortcomings that.
2) the ideal torque of arc sliding portion and arc-shaped guide rail transmits plane A (the i.e. equivalent substitution of scraper bowl and material gravity
Plane) it is overlapped with torque actual transfer plane B (practical arc-shaped guide rail actual loading equivalent plane), torque transmission efficiency is higher.
3) when discharging rotates, bucket lip moves out trend, effective to increase unloading distance, in slag-soil truck and loads
Machine keeps the unloading that material can be efficiently accomplished while certain distance.
