(it is higher than ship storehouse Bulk Grain plane, and bucket lifting device 2 keeps hanging down with horizontal plane always during movement after lifting certain altitude
Directly), by double-crank hydraulic pressure lever apparatus 34 between spiral feeder apparatus 4 and bucket lifting device 2 (i.e. hyperbolic handle structure,
Claim double-crank four-bar mechanism), realize and the operating angle between spiral feeder apparatus 4 and bucket lifting device 2 is adjusted, adjust
After whole to 90 °, double-crank hydraulic pressure lever apparatus 34 is automatically locked, and realizes the preparation state of spiral feeder apparatus 4.It is then turned on
Bucket lifting device 2, spiral feeder apparatus 4 is opened, open revolution attachment means 3.The motion of revolution attachment means 3 is by returning
Turn the rotation driving pinion 31 of attachment means motor 29 to move, little gear 31 drives gear wheel 30 to move, and is connected to so as to drive
The screw feeding device 4 for turning round the lower end of attachment means 3 produces gyration.The device of helical blade 27 on spiral feeder apparatus 4
The Bulk Grain around in cabin is set to gather to tail wheel (i.e. bottom tail wheel) place of bucket lifting device 2.Winnowing pan 18 contains Bulk Grain with dustpan
Bucket band vertical-lift, is promoted to discharging opening, and the drive to run at high speed throws out Bulk Grain, and Bulk Grain is defeated through elephant trunk arrival belt
The tail end (i.e. feeding end) of device 1 is sent, the other end (i.e. delivery end) of the device is and then transported to, then, due to gravity
Effect, the harbour that Bulk Grain is entered below the ship unloaders centre of gyration by elephant trunk receive conveyer.Whole process to close, it is dustless,
The mode of No leakage is carried out, and the new ship unloaders utilize 4 automatic loose metal of spiral feeder apparatus and driving, using the walking of door frame 5,
The revolution of fuselage and the hydraulic stem 6 of luffing mechanism make head reach each position in cabin, ensure material with higher unloading
Rate is constantly efficiently transported in ship unloaders induction system.
It can be first shut off turning round the electricity of attachment means 3 when the induction contact of the tail end of spiral feeder apparatus 4 is by related stimulus
Machine rotating switch, stop the gyration of spiral feeder apparatus 4.After spiral feeder apparatus 4 stops completely, corresponding induction installation is just
Hyperbolic handle structure can be driven, and then realizes that the operating angle between spiral feeder apparatus 4 and bucket lifting device 2 is adjusted,
To 0 °, hyperbolic hydraulic stem 37 is automatically locked adjustment angle, so as to carry out the withdrawal of spiral feeder apparatus 4, then only passes through bucket type
Lifting device 2 most under exposed winnowing pan 18 realize unloading and cleaning to corner Bulk Grain.
Embodiment 3
On the basis of embodiment 2, after embodiment 2 are completed, the Bulk Grain in cabin is unloaded substantially to be finished.By bowing
Face upward mechanism hydraulic pressure lever apparatus 6 bucket lifting device 2 is first lifted into certain altitude after (be higher than ship storehouse Bulk Grain plane), pass through spiral shell
The double-crank hydraulic pressure lever apparatus between drawing-in device 4 and bucket lifting device 2 is revolved, realizes and spiral feeder apparatus 4 is carried with bucket type
The operating angle risen between device 2 is adjusted, and after being adjusted to 90 °, hyperbolic hydraulic stem 34 is automatically locked, and realizes that screw feed fills
Put 4 preparation state.Spiral feeder apparatus 4 is then turned on, opens revolution attachment means 3.Pass through the hydraulic pressure of luffing mechanism
The device of bar 6, which reduces spiral feeder apparatus, makes its bottom surface be contacted with Bulk Grain face, now turns round the rotating speed of attachment means 3 and is adjusted to compared with low speed
Degree, brings down stocks work so as to start hull bottom, can realize complete cleaning in theory.When the underlying metal inductor of spiral feeder apparatus 4
When sending alarm, ship unloaders can stop operation.
It should be noted that 1200 tons of yield of this ship unloaders theoretical maximum design/when, due to when screw feeding device 4 and bucket
When formula lifting device 2 is in 90 °, operation is relatively large in diameter, and is not suitable for hull size and is less than 2.5 times of ships of operation diameter.When spiral enters
Material device 4 is when adjusting as bucket lifting device 2 into 0 °, can with operation in smaller ship, but can have with Theoretical Design yield compared with
It is big to come in and go out.
It should be noted that this ship unloaders can do ultra-large type when screw feeding device 4 and bucket lifting device 2 are in 90 °
Ship brings down stocks equipment use, there is higher service efficiency.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
