[0030] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] First see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an embodiment of a vibration device for a silo according to the present utility model; Figure 2 This is a structural diagram of another embodiment of the vibration device for a silo of the present invention. Figure 1 As shown, the vibrating device for a silo includes a transmission assembly 2 and a vibrator 3. The transmission assembly 2 can be mounted on the outer wall of the conical section of the silo 1 and arranged parallel to the hypotenuse of the longitudinal section of the conical section. The transmission assembly 2 can drive the vibrator 3 to slide back and forth along the length of the transmission assembly 2.

[0035] Although Figure 1 and Figure 2 The example of providing one vibration device on the silo 1 is shown, but those skilled in the art may provide two or more vibration devices according to the size of the silo or the material transmission conditions.

[0036] like Figure 2 As shown, the transmission assembly 2 includes a slider 21, two lead screws 22, two bearing blocks 24, and two motors. The two lead screws 22 rotatably pass through the slider 21, on which the vibrator 3 is fixed. Therefore, when the two lead screws 22 rotate, they can drive the slider 21 and the vibrator 3 to move axially along the lead screws 22.

[0037] Each end of the two lead screws 22 is provided with a bearing seat 24, through which the lead screws 22 rotatably pass. The bottom of the bearing seat 24 is fixedly connected to the outer wall of the silo 1. A drive motor 23 is also connected to one end of each lead screw 22. In operation, the drive motor 23 drives the lead screw 22 to rotate relative to the bearing seat 24, causing the slider 21 to move. This allows the position of the vibrator 3 to be adjusted, improving the flexibility of the vibration device.

[0038] See also Figure 3 and continue to refer back Figure 1 , Figure 3 FIG. 1 is a schematic structural diagram of an embodiment of the transmission assembly of the present utility model. Figure 1 and Figure 3 As shown, a plurality of rollers 25 are provided at the bottom of the slider 21, and the rollers 25 engage with the outer wall of the silo 1. Therefore, the rollers 25 can slidably connect the slider 21 to the silo 1, reducing the friction between the slider 21 and the silo 1 when the slider 21 moves. At the same time, the rollers 25 can also support the slider 21 and prevent the slider 21 from shaking during movement.

[0039] See last Figure 4 , Figure 4FIG. 1 is a structural diagram of an embodiment of a vibrator of the present invention. Figure 4 As shown, the vibrator 3 includes a shell 31 , and an air inlet is provided on the top of the shell 31 . The air inlet is connected to an external air source through an air pipe, and a solenoid valve can be provided on the air pipe.

[0040] The housing 31 also contains a chamber connected to the air inlet. A base plate 34 is located within the chamber and has a through hole. The base plate 34 divides the chamber from top to bottom into an air chamber 35 and a sliding chamber 36. The air chamber 35 also has an exhaust hole connected to the outside via an exhaust pipe equipped with a shutoff valve. A piston rod 32 is slidably mounted within the sliding chamber 36. A piston ring 37 and a sealing ring 38 are mounted on the piston rod 32, ensuring a tight engagement between the piston rod 32 and the sliding chamber 36.

[0041] Furthermore, the vibrator 3 is further provided with a spring 33 , which is sleeved on the piston rod 32 , with an upper end connected to the piston rod 32 and a lower end connected to the bottom of the sliding cavity 36 .

[0042] In the working state, the solenoid valve on the air inlet pipe is opened, so that the external air source passes through the air cavity 35 through the base plate 34, causing the piston rod 32 to compress the spring 33 downward until the piston rod 32 hits the slider 21. Next, the solenoid valve is closed and the stop valve on the exhaust pipe is opened. In this way, the gas in the air cavity 35 will be discharged from the exhaust pipe. As the gas is discharged, the spring 33 gradually recovers, causing the piston rod 32 to return to its initial position. The solenoid valve and the stop valve are constantly opened and closed in an alternating manner, allowing the piston rod 32 to reciprocate in the sliding cavity 36, periodically hitting the slider 21, causing the material in the silo 1 to vibrate, thereby destroying the adhesion and internal friction between the materials, promoting the flow of materials, and avoiding material blockage or accumulation.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
