DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a double-opening silo door driving mechanism, referring to Figure 1 and Figure 2 , including a mounting frame 1, on which two parallel first rotating shafts 2 are rotatably connected, and a silo door (not shown in the figure) is bolted to the two first rotating shafts 2. The ends of the two first rotating shafts 2 on the same side extend out of the mounting frame 1, and a driving piston cylinder 3 is installed on the side wall of the mounting frame 1. The piston rod of the driving piston cylinder 3 is drivingly connected to the end of the first rotating shaft 2 extending out of the mounting frame 1, and the driving piston cylinder 3 is used to drive the first rotating shaft 2 to rotate.

[0020] A double-opening silo door driving mechanism of an embodiment of the present application is installed in a mixer and is used to drive the two silo doors of the mixer to open / close. When the materials in the mixer are evenly mixed, the two first rotating shafts 2 can be driven to rotate by starting the driving piston cylinder 3 to open the two silo doors and unload. After the unloading is completed, the driving piston cylinder 3 drives the first rotating shaft 2 to rotate back to close the two silo doors. Compared with the traditional unloading method, the double-opening silo door driving mechanism of the present application no longer requires the staff to manually push and pull the silo doors. Only the driving piston cylinder 3 needs to be started to open the two silo doors for unloading. It has the effect of simple operation and reduced labor intensity.

[0021] Reference Figure 3 , a connecting rod assembly 4 is installed on the mounting frame 1, and the driving piston cylinder 3 drives the two rotating shafts to rotate synchronously in opposite directions through the connecting rod assembly 4. The connecting rod assembly 4 includes a rotating plate 41, and a second rotating shaft 5 is parallel to the first rotating shaft 2 and rotatably connected to the mounting frame 1 at an upper position between the two first rotating shafts 2, and the middle part of the rotating plate 41 is welded to the second rotating shaft 5. Both ends of the rotating plate 41 are rotatably connected to the pull rods 42, and the ends of the two pull rods 42 away from the rotating plate 41 are rotatably connected to the connecting rods 6 respectively. The end of the connecting rod 6 away from the pull rod 42 is welded to the first rotating shaft 2, the cylinder body of the driving piston cylinder 3 is hinged on the mounting frame 1, and the end of the piston rod of the driving piston cylinder 3 away from the cylinder body is rotatably connected to one end of the rotating plate 41, and the angle between the pull rod 42 and the connecting rod 6 is in an acute angle state before the connecting rod assembly 4 drives the silo door to open.

[0022] In the embodiment of the present application, the driving piston cylinder 3 is started to retract the piston rod into the cylinder body, so that the rotating plate 41 can be rotated, thereby driving the two connecting rods 6 to rotate synchronously in the opposite direction through the pull rods 42 at both ends. Since the end of the connecting rod 6 away from the pull rod 42 is welded and fixed to the corresponding first rotating shaft 2, the two first rotating shafts 2 also rotate synchronously in the opposite direction with the two connecting rods 6, thereby achieving the purpose of opening the two silo doors at the same time. After the unloading is completed, the driving piston cylinder 3 drives the piston rod to extend out of the cylinder body, and the two silo doors can be closed synchronously.

[0023] Specifically, the driving piston cylinder 3 is a gas cylinder 31. In other embodiments of the present application, the driving piston cylinder 3 may also be a hydraulic cylinder or other components.

[0024] Furthermore, both ends of the pull rod 42 are equipped with adjusting members 7 for adjusting their own length. The adjusting member 7 includes an adjusting screw 71, and both ends of the pull rod 42 are provided with threaded holes whose sizes match the adjusting screw 71. One end of the adjusting screw 71 is threadedly connected in the threaded hole, and a connecting ring 72 is welded to the end of the adjusting screw 71 away from the pull rod 42. A connecting shaft 8 is inserted into the inner side of the connecting ring 72, and a through hole with a size identical to the inner diameter of the connecting ring 72 is provided at the position where the rotating piece 41 / connecting rod 6 is rotatably connected to the pull rod 42, and the connecting shaft 8 is movably inserted into the through hole. The connecting ring 72 is rotatably connected to the corresponding rotating piece 41 / connecting rod 6 through the connecting shaft 8, and a plurality of limit assemblies 9 for limiting the corresponding connecting shaft 8 from sliding out of the connecting ring 72 are installed on the rotating piece 41 / connecting rod 6.

[0025] In practical applications, the spacing between the two silo doors of different models of mixers is different. For the double-opening silo door driving mechanism of the present application, the connecting shaft 8 can be taken out by unfastening the limit assembly 9, and then the adjusting screw 71 can be rotated to adjust its length in the threaded hole, thereby adjusting the overall length of the pull rod 42, so as to adapt to the two silo doors with different spacings.

[0026] Reference Figure 4 The limiting assembly 9 includes a limiting piece 91 and a limiting bolt 92. Both ends of the connecting shaft 8 pass through the rotating piece 41 / connecting rod 6, and an annular groove whose size matches the thickness of the limiting piece 91 is opened on the side wall of the part passing through the rotating piece 41 / connecting rod 6. The limiting pieces 91 are inserted into the annular grooves one by one, and the limiting pieces 91 are in sliding contact with the bottom wall of the annular groove. The limiting pieces 91 are connected to the corresponding rotating piece 41 / connecting rod 6 through the limiting bolt 92.

[0027] After the connecting shaft 8 passes through the connecting ring 72 and the corresponding rotating plate 41 / connecting rod 6, the limiting plate 91 is inserted into the ring groove, and the limiting plate 91 is installed on the corresponding rotating plate 41 / connecting rod 6 by the limiting bolt 92, so as to prevent the connecting shaft 8 from slipping out of the connecting ring 72 during the process.

[0028] In order to facilitate the connection shaft 8 to pass through the through hole and the inner side of the connection ring 72 , chamfers 81 are provided at both ends of the connection shaft 8 .

[0029] The implementation principle of a double-opening silo door driving mechanism in an embodiment of the present application is as follows: when the materials in the mixer are evenly mixed, the driving piston cylinder 3 can be started to drive the rotating plate 41 to rotate, thereby driving the connecting rod 6 to drive the two first rotating shafts 2 to rotate synchronously in the opposite direction through the pull rods 42 at both ends, so as to open the two silo doors and discharge. After the unloading is completed, the driving piston cylinder 3 drives the first rotating shaft 2 to rotate back, and the two silo doors can be closed. Compared with the traditional unloading method, the double-opening silo door driving mechanism of the present application no longer requires the staff to manually push and pull the silo doors. It only needs to start the driving piston cylinder 3 to open the two silo doors for unloading. It has the effect of simple operation and reduced labor intensity.
