Further, the setting that is inclined upwardly of said first connecting axle, the downward-sloping setting of second connecting axle, the length of connecting axle is shorter than the length of connecting rod.
Further; Saidly between cylinder and connected hopper, be provided with the adjusting device that is used to adjust the Dump gate aperture; This adjusting device can move in the travel range of cylinder; This adjusting device comprises the bearing that is fixed on the hopper and is arranged on the stay bolt on the bearing that stay bolt can be in the bearing adjusted.
Further, the base plate of said first, second Dump gate is straight plate.
Further, be provided with a mount pad between said first, second Dump gate and hopper, this mount pad is hinged with first, second Dump gate and be fixedly connected with hopper, and mount pad is provided with and is used to governor motion that first, second Dump gate is moved up and down.
Further, said height adjustment mechanism is for being opened in symmetrical waist-shaped hole on the mount pad, and mount pad is fixedly connected with hopper through the screw rod that passes waist-shaped hole.
The utlity model has following beneficial effect:
According to the extra quality door device for discharging that the utility model provides, overcome the deficiency of original device, only need a cylinder to control the switch of two discharge doors simultaneously, and the stroke of required cylinder is shorter, cylinder diameter is littler; The door-plate of discharge door is set to straight plate, when discharging, is difficult for sizing and discharge rate is faster; Can prevent to get stuck, leak material according to the height of the size adjustment discharge door of aggregate through the governor motion on the mount pad.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Sketch map when Fig. 1 closes for the extra quality door of present embodiment device for discharging.
Sketch map when Fig. 2 is the unlatching of the extra quality door of present embodiment device for discharging.
The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, shown in Figure 2, the extra quality door device for discharging of the utility model, this device for discharging is arranged at discharging opening one end of hopper 1, and this device for discharging comprises Dump gate assembly 2, connecting rod 3, mount pad 4, cylinder 5 and aperture governor motion 6.Dump gate assembly 2 is made up of symmetrical first Dump gate 21 and second Dump gate 22, and first Dump gate 21 is by forward and backward side plate 211 and base plate 212 besieged cities, and side plate 211 is provided with acclivitous first connecting axle 213; Second Dump gate 22 is by forward and backward side plate 221 and base plate 222 besieged cities, and side plate 221 is provided with the second downward-sloping connecting axle 223; Base plate 212 and 222 is symmetrically arranged straight plate.The length of connecting rod 3 is longer than two connecting axles 213,223, and the two ends of connecting rod 3 are hinged with first connecting axle 213 and second connecting axle 223 respectively.Mount pad 4 is provided with installation shaft and first, second Dump gate 21,22 is hinged, and the right and left of mount pad 4 respectively has waist-shaped hole 41, and mount pad 4 is fixedly connected with hopper 1 through the screw rod that passes waist-shaped hole 41.The body-fixed of cylinder 5 is on hopper 1, and the piston rod of its output is connected with first Dump gate 21.Aperture governor motion 6 comprises support 61, long bolt 62, and support 61 is arranged on 21 of cylinder 5 and first dump skips, and screw rod 62 can move on support, and this screw rod 62 moves in cylinder is stretched the travel range of 5 piston rods.
