Description

Technical Field

[0001] The utility model relates to the technical field of powder material storage, in particular to an electric valve stem. Background Art

[0002] When feeding powdered or granular materials into the interior of a silo, multiple conveying pipes are usually set at the opening of the silo for feeding different types of materials. When feeding materials, the wrong materials are usually fed in due to operational errors of the staff. In order to avoid this kind of incident, it is necessary to install an electric valve stem at the discharge end of the conveying pipe to seal the discharge port of the conveying pipe. This can solve the problem of feeding the wrong materials. However, there are many conveying pipes at the opening of the silo and they are arranged relatively densely. If the electric valve stem is installed, it is usually impossible to install the electric valve stem because the gap between the two conveying pipes is too small. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: an electric valve stem, including a rotating frame with a mounting frame arranged on one side of the mounting frame, both sides of the rotating frame can be removably installed on the side wall of the mounting frame, a rocker arm is installed inside the rotating frame, and a driving source is installed at the rotating position of the rocker arm, and a sealing plate for sealing the delivery pipe is installed at one end of the rocker arm.

[0005] Furthermore: the rotating frame includes a first mounting plate and a second mounting plate, and the first mounting plate and the second mounting plate are arranged parallel to each other, and a same connecting plate is fixed between the first mounting plate and the second mounting plate.

[0006] Furthermore: the first mounting plate and the second mounting plate are both provided with mounting holes at their corners, and the mounting frame is provided with first bolts for use with the mounting holes.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0021] Embodiments of the present utility model:

[0022] An electric valve stem includes a mounting frame 1 and a clamp 10 arranged on one side of the mounting frame 1, and through holes are opened on both sides of the clamp 10. A second bolt 11 passes through the through holes and is threadedly connected to the mounting frame 1, so that the mounting frame 1 can be fixed on the delivery pipe a.

[0023] A rotating frame 2 is provided on the other side of the mounting frame 1, and a rocker arm 3 is installed inside the rotating frame 2. A driving source is detachably installed at the rotating position of the rocker arm 3, and the driving source can be a motor. A sealing plate 4 is installed at the end of the rocker arm 3 away from the rotating frame 2. The setting of the sealing plate 4 plays a role in sealing the conveying pipe a, thereby preventing the granular material or powdered material in the conveying pipe a from being discharged from the inside of the conveying pipe.

[0024] Specifically, the rotating frame 2 includes a first mounting plate 21 and a second mounting plate 22, and the two first mounting plates 21 and the second mounting plates 22 are arranged parallel to each other, and a same connecting plate 23 is fixed between the first mounting plate 21 and the second mounting plate 22. The setting of the connecting plate 23 plays a role in fixing the first mounting plate 21 and the second mounting plate 22. The first mounting plate 21 and the second mounting plate 22 are both provided with mounting holes 24 at the corners, so that the first mounting plate 21 and the second mounting plate 22 can be installed on the side wall of the mounting frame 1. The mounting frame 1 is installed with a first bolt 25 for use with the mounting hole 24. The setting of the first bolt 25 plays a role in fixing the first mounting plate 21 or the second mounting plate 22.

[0025] Specifically, the rocker arm 3 includes a rotating disk 31, and a rotating shaft is fixed at the center of the rotating disk 31, and the rotating shaft 32 passes through the second mounting plate 22 and is detachably connected to the output shaft of the driving source, so that the driving source can be disassembled. An "L"-shaped connecting rod 32 is fixed on the rotating disk 31. It should be noted that ribs 9 are fixed at the corners of the connecting rod 32. The setting of the ribs 9 reinforces the connecting rod 32 to prevent the connecting rod 32 from deformation during use. A mounting disk 33 is fixed to the end of the connecting rod 32 away from the rotating disk 31, and the sealing plate 4 is installed on one side of the mounting disk 33. The setting of the rocker arm 3 can drive the sealing plate 4 to swing.

[0026] A baffle 5 is fixed on one side of the connecting rod 32, and a first limiting plate 6 is also fixed between the first mounting plate 21 and the second mounting plate 22. A bracket 7 is fixed on one side of the first mounting plate 21, and a second limiting plate 8 is fixed on the top of the bracket 7. Through the setting of the baffle 5, the first limiting plate 6 and the second limiting plate 8, the connecting rod 32 is limited so that the maximum rotation angle of the connecting rod 32 is 90 degrees.

[0027] When installing the electric valve stem, first put one side of the clamp 10 on the delivery pipe a, and then use the second bolt 11 to pass through the clamp 10 to connect it to the mounting frame 1, thereby fixing the mounting frame 1; then install the rotating frame 2 on the mounting frame 1. There are two ways to install the rotating frame 2. This application can be used in any of the following ways;

[0028] First installation method: When installing the rocker arm 3, first align one side of the first mounting plate 21 with one side of the mounting frame 1, and position the second mounting plate 22 away from the mounting frame 1. Then, use the second bolt 25 to pass through the mounting frame 1 and thread it into the mounting hole 24 on the first mounting plate 21. Then, install the drive source on the second mounting plate 22 again, and connect the output end of the drive source to the rotating disk 31.

[0029] Second installation method: When installing the swing arm 3, the rotating frame 2 is rotated 180 degrees horizontally so that one side of the second mounting plate 22 is aligned with the mounting frame 1, thereby changing the orientation of the second mounting plate 22. Then, a second bolt 25 is passed through the mounting holes 24 on the mounting frame 1 and the second mounting plate 22 to connect them. The drive source is then installed on the mounting frame 1 again so that the output shaft of the drive source passes through the mounting frame 1 and is connected to the rotating disk 31.

[0030] Therefore, the position of the driving source can be adjusted according to the requirements of the surrounding space, avoiding the situation where the driving source cannot be installed due to the space being too narrow.

[0031] If the material in the conveying pipe a is transported incorrectly, the driving source is turned on, and the output shaft of the driving source can drive the rocker arm 3 to swing, so that the sealing plate 4 at one end of the rocker arm 3 rotates and blocks the discharge port of the conveying pipe a, so that corresponding measures can be taken in time to prevent the wrong material from being discharged.
