Abstract

Disclosed is a linked door-opening device of a mixing machine. At the external portion of a shell, a cylinder spindle nose 5 is separately connected with a drive shaft 9 and a driven shaft 3 via a driving rocking bar 8, an outer connecting bar 2 and an outer driven rocking bar 1, and the cylinder spindle nose 5 can drive the drive shaft and the driven shaft to rotate simultaneously. At the internal portion of the shell, the drive shaft and the driven shaft which extend into the shell are respectively connected with two discharging doors I 10, II15 via inner driven rocking bars I 13, II 18 and inner connecting bars I 12, II 17, two rotating shafts I 6, II 14 which extend into the shell are fixedly connected with the two discharging doors I, II respectively, thereby the rotation of the drive and driven shafts can drive the two doors to move around the two rotating shafts, which leads to the opening and closedown of the two doors, and the opening angle can achieve more than 90 degrees.

Description

Mixer interlock door opener

The utility model is a kind of interlock door opener that is used for various dissimilar mixers, belongs to the mixing machinery technical field, can be used for industries such as feed, grain and oil, fertilizer and building materials.

At present, known mixer door opener by cylinder, drive crank, the rocking bar that opens the door, open the door the axle and the channel-section steel that opens the door form, the rocking bar arm of force that opens the door of this door opener is very short, and therefore required cylinder thrust is bigger, so a general cylinder can only be controlled a discharge door; Simultaneously, this door opener is subjected to the restriction of itself structure, and its maximum open angle generally can only be about 60 degree, and this has just caused the mixer discharging time long and residual material is many, particularly, tend to cause serious discharging not smooth for the bigger high moisture material of viscosity ratio.

The purpose of this utility model provides a kind of novel mixer interlock door opener, this device need only be with a cylinder by linkage two fan-out bin gates of opening and closing simultaneously just, and can make the discharge door opening angle greater than 90 degree, can shorten discharging time like this, reduce material residual quantity in the door.

The technical solution of the utility model is: in body casing 7 outsides, the cylinder spindle nose 5 of cylinder 4 and drive crank 8 upper ends flexibly connect, and the drive crank other end is fixedlyed connected with driving shaft 9, and driving shaft is movably connected on the body casing 7.The middle part of drive crank 8 and outside connecting rod 2 flexibly connect, and the outside connecting rod other end and outer driven rocking bar 1 flexibly connect, and the outer driven rocking bar other end is fixedlyed connected with driven shaft 3, and driven shaft is movably connected on the body casing 7.Stretching out with indentation of cylinder spindle nose just can drive the rotation of driving shaft and driven shaft simultaneously like this, and driving shaft is identical with the driven shaft anglec of rotation, but direction of rotation is opposite.Flexibly connect two rotating shaft I 6, II 14 on casing 7 above driving shaft 9 and the driven shaft 3 respectively, driving shaft, driven shaft and two rotating shafts all pass the casing housing and extend into enclosure interior.In body casing 7 inside, the driving shaft 9 that puts in body casing inside is fixedlyed connected with driven rocking bar I 13 in the 3-10 root, driven rocking bar I and 3-10 root inside connecting rod I 12 flexibly connect in the 3-10 root, and the 3-10 root inside connecting rod I other end leans on an end at middle crack between a door and its frame place to flexibly connect by connector I 11 in the 3-10 root and discharge door I 10.The keep to the side other end at upper shell plate place of discharge door I 10 is fixedlyed connected with rotating shaft I 6.The rotation of driving shaft is the axle center rotation by interior driven rocking bar I, inside connecting rod I and interior connector I drive discharge door I with rotating shaft I just like this, reaches the purpose that makes discharge door I opening and closing.The driven shaft 3 that puts in casing inside is fixedlyed connected with driven rocking bar II 18 in the 3-10 root, driven rocking bar II and 3-10 root inside connecting rod II 17 flexibly connect in the 3-10 root, and the 3-10 root inside connecting rod II other end leans on an end at middle crack between a door and its frame place to flexibly connect by connector II 16 in the 3-10 root and discharge door II 15.The keep to the side other end at upper shell plate place of discharge door II is fixedlyed connected with rotating shaft II 14.From said structure as can be seen, it is the axle center rotation with rotating shaft II that the rotation of driven shaft also drives discharge door II by interior driven rocking bar II, inside connecting rod II and interior connector II, reaches the purpose that makes discharge door II opening and closing.Because of the direction of rotation of driving shaft and driven shaft is opposite, thereby two fan-out bin gates can reach do the action of opening the door or doing simultaneously to close the door to the centre to both sides simultaneously under the drive of same cylinder.The flexible length of cylinder spindle nose can determine the size of the anglec of rotation of driving shaft and driven shaft, driving shaft, the driven shaft anglec of rotation are big, the open degree of door is just big, otherwise, driving shaft, the driven shaft anglec of rotation are little, the open degree of door is just little, therefore only needs to adjust the open degree that the flexible length of cylinder spindle nose just can be adjusted door.The door opener of this structure can make a downward open degree reach more than 90 degree.

Owing to adopt technique scheme, this door opener has only just reached the purpose that makes two fan door opening and closing simultaneously with a cylinder, and the angle that two fan doors are opened can reach more than 90 degree, has so just shortened discharging time greatly, and has reduced the residual quantity of material in the door.

The utility model will be further described below in conjunction with drawings and Examples.
