Machine 8, the first filter screen 23, the second filter screen 24, feeding door 7 and cleaning door 51,4 height of second charging aperture are lower than first charging aperture
3, bucket body 2 is arranged on bracket 1, and the setting of vibrating motor 8 is pushed up in 2 lower outside face of bucket body, the setting of first charging aperture 3 in bucket body 2
Face feeds intake for ton bag, and second charging aperture 4 is arranged on bracket 1 and passes through conveying pipeline 71 diagonally downward and 2 side of bucket body
Connection, for feeding intake for purse, the first dust excluding hood 5 and the second dust excluding hood 6 are arranged on bracket 1 and divide second charging aperture 4
Not Wei Rao first charging aperture 3 and second charging aperture 4 arrange that the first dust excluding hood 5 and the second dust excluding hood 6 all have outlet 11, should go out
It is provided with round tube hangnail 12 at mouth 11, round tube hangnail 12 is flexible coupling with depression dust-removing mechanism, and depression dust-removing mechanism is specifically tied
Structure is the prior art.
Unpacking mouth is arranged on bucket body 2, and unpacking mouth is about highly from the ground 1200mm, this can highly facilitate operator
It stands and carries out unpacking work, unpacking door 21 is arranged at unpacking mouth, to open or close unpacking mouth, in the present embodiment, tears open
Bag door 21 using existing quick-speed jigs lock, with this guarantee unpacking door 21 compress sealing and being capable of high-speed switch.Unpacking door 21
On be provided with the first dust removal port, which exports 11 by hose 22 and the first dust excluding hood 5 and is connected to.
Feeding door 7 is arranged on bracket 1, and to close or open second charging aperture 4, feeding door 7 is using existing quick
Fixture locking, with this guarantee feeding door 7 compress sealing and being capable of high-speed switch.The setting of saddle 9 is at second charging aperture 4 and outside
Extend, operation when facilitating purse to feed intake, in the present embodiment, 4 height of second charging aperture is 80mm, is fully considered man-machine
Best fit state.
First filter screen 23 and the second filter screen 24 are located at 4 lower section of first charging aperture 3 and second charging aperture, specifically
, the first filter screen 23 is located in the bucket body 2 below unpacking mouth, and unpacking door 21 can be directly opened after discharging and has been checked whether
Sundries, if so, directly cleaning out from unpacking mouth, the second filter screen 24 is arranged in conveying pipeline 71, can after feeding intake
Whether have sundries, if so, directly cleaning out from the taking-up of second charging aperture 4 if being directly viewable at filter screen.
First dust excluding hood 5 and the second dust excluding hood 6 include three risers 10, three risers 10 around first charging aperture 3 or
Person's second charging aperture 4 arranges that the riser 10 is porous plate.
Two cleaning doors 51 are respectively arranged on the opposite riser 10 of the two of first dust excluding hood 5, for clearing up for a long time first
The dust accumulated in dust excluding hood 5.
The operation principle of the present invention is that:
When ton bag discharging, ton bag by electric block or fork truck handling (fork fortune) to first above bucket body 2 into
Material mouth 3, after alignment first charging aperture 3 is slowly dropped to appropriate location, operator, that is, openable unpacking door 21 carries out unpacking discharging,
