Being connected through a screw thread, and link position is provided with nut 1548 is used to fix.
Such as Fig. 7 and Fig. 8, when opening-locking mechanism 100 has alignment error, the neck 1566 of clamping mechanism 150 can not be accurate
, it is necessary to adjust the length of connecting rod 154 when really being caught in steady pin 172.Now, it is only necessary to unclamp nut 1548, then rotate
Connecting cylinder 1546.Due to the two ends of connecting cylinder 1546 thread rotary orientation on the contrary, therefore first connecting rod 1542 and second connecting rod 1544 simultaneously
Remote or close motion is done relative to connecting cylinder 1546, so as to reach the purpose of the adjustment length of connecting rod 154.
Whole opening-locking mechanism 100 by fixture 160 and is treated when with fixture 160, the assembling of part to be opened 170, first
Opening tool 170 is hinged by rotary shaft 162；Then clamping mechanism 150 is rotatably connected by connecting shaft 152 with fixture 160
Connect, and bearing pin 1564 is fixedly connected on to the side plate of fixture 160, spring 1568 is fixedly connected on fixture 160, adjustment connection
The length of bar 154, so that neck 1566 is caught in steady pin 172；Finally by the first pedestal 130 of screw mechanism 110 with fixing machine
The connecting shaft 152 of structure 150 is fixedly connected, and the second pedestal 140 is fixedly connected with part 170 to be opened.
Such as Fig. 8 and Fig. 9, opening-locking mechanism 100 is used for unlatching of the part 170 relative to fixture 160 to be opened and locking,
Part 170 and fixture 160 to be opened are hinged.After drive mechanism 120 is powered, drive mechanism 120 drives thread spindle 112 around itself
Axis is rotated；Because thread spindle 112 and thread barrel 114 are connected by trapezoidal thread, and thread barrel 114 around own axes from
Constrained by spending by the second pedestal 140；Therefore thread spindle 112 and thread barrel 114 are close to each other or remote in the axial direction, so that
The first pedestal 130 and the second pedestal 140 is driven to do motion close to each other or remote；Outer spiral shell of the steel band 116 to screw mechanism 110
Line section 1122 forms protective layer, prevents particle from entering spiral engaging portion.When the thread spindle 112 and screw thread of screw mechanism 110
Cylinder 114 is when axis direction is done close to motion, and distance reduces between the first pedestal 130 and the second pedestal 140, so that in the first base
Under the drive of seat 130, connecting shaft 152 does the rotation in A directions, because the first pedestal 130 is fixedly connected with connecting shaft 152, so that
Connection end 1522 pulls connecting rod 154, pulls holding division 156 to make it around being arranged on the side plate of fixture 160 by connecting rod 154
Bearing pin 1564 do the rotation in B directions, neck 1566 releases the locking to steady pin 172 away from steady pin 172；Work as connecting shaft
152 turn to maximum angle when stopping operating, and the second pedestal 140 drives part 170 to be opened to be rotated along C directions；With to be opened
The rotation of part 170, part 170 to be opened can be opened completely.When the thread spindle 112 and thread barrel 114 of screw mechanism 110 are in axis
When direction is done away from motion, the direction of motion of above-mentioned each part is on the contrary, repeat no more.
The mechanism of open-and-close is carried out using hydraulic system in the prior art, maintenance is bad to cause oil leakage of hydraulic system,
So that locking mechanism locking is unreliable.The opening-locking mechanism 100 that the present embodiment is provided, screw mechanism 110 can be with self-locking, it is ensured that
Locking is reliable.
It should be noted that in the present embodiment or the first pedestal 130 is connected with part 170 to be opened, the second pedestal
140 are connected with fixture 160.Also, the part to be opened 170 and fixture 160 in figure are schematic diagram, its structure is not limited to
Schematic structure.
Embodiment 2：
Such as Figure 10, a kind of baler 200 is present embodiments provided, the baler 200 includes forebay 210, afer bay 220
The opening-locking mechanism 100 provided with embodiment 1.First pedestal 130 is connected to forebay 210, after the second pedestal 140 is connected to
Frame 220.In the presence of opening-locking mechanism 100, afer bay 220 can be opened or locking relative to forebay 210.Work as opening
During afer bay 220, bale 230 can be released from bundling house.
The baler 200 that the present embodiment is provided, its opening-locking mechanism 100 is simple in construction, easy to maintenance, it is only necessary to periodically
Threaded portion is carried out oily.Further, since steel band 116 can be protected to threaded portion formation, therefore rapid wear is not allowed by the mechanism
It is bad.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former
Within then, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
