[0007] To this end, we provide a transducer sealing installation structure for a vibrating screen to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of the utility model is to provide a transducer sealing installation structure for a vibrating screen, which seals the vibrating screen and the transducer through a sealing component to avoid leakage, and can fix transducers of different sizes through a fixing component, while having a certain protective effect, thereby solving the problem that the existing transducer sealing installation structure for a vibrating screen cannot protect the transducer.

[0009] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0010] The utility model is a transducer sealing installation structure of a vibrating screen, comprising a screen frame and a screen mesh, wherein the screen mesh is installed on the inner side wall of the screen frame, a fixing component is installed on the outer side wall of the screen frame, and a sealing component is installed on the outer side wall of the screen mesh; a connecting column is installed on the outer side wall of a sealing rubber ring of the sealing component, a sealing ring is installed on the outer side wall of the connecting column, and a transducer is installed on the right side wall of the connecting column; a fixing block is installed on the upper side wall of a load-bearing block of the fixing component, a buffer spring is installed on the inner side wall of the load-bearing block, a protective pad is installed on the moving end of the buffer spring, and a fixing column is installed on the left side wall of the load-bearing block.

[0012] The utility model is further configured such that the left side wall of the connecting column is fixedly connected to the sealing rubber ring, an installation groove is provided on the inner side of the sealing rubber ring, and the sealing rubber ring wraps the screen through the installation groove.

[0013] The utility model is further configured that an inner wall of the connecting column is provided with an internal thread, the connecting column is connected to the transducer via the internal thread, and an outer wall of the connecting column is slidably connected to the sealing ring.

[0014] The utility model is further configured such that the outer side wall of the transducer wraps the protective pad, and the outer side wall of the transducer is closely connected to the protective pad.

[0015] The utility model is further configured such that the protection pad is fixedly connected to the moving end of the buffer spring, and the fixed end of the buffer spring is fixedly connected to the load-bearing block.

[0016] The utility model is further configured that one end of the upper side wall of the load-bearing block is connected to the fixed block through a rotating shaft, and the other end of the load-bearing block is connected to the fixed block through a fixing bolt.

[0017] The utility model is further configured such that the left side wall of the load-bearing block is fixedly connected to the fixed column, and the left side wall of the fixed column is fixedly connected to the screen frame.

The screening effect is better during operation, and the problem of energy loss and reduced work efficiency caused by working through a fixed plate fixedly connected to the vibrating screen is solved.

[0020] The utility model sets a fixing component and rotates the fixing block. The fixing block rotates in a circle around the rotating shaft, thereby making the fixing block and the load-bearing block open, which is convenient for placing the transducer on the protective pad.

At this time, the two protection pads on the inner wall will wrap the transducer to avoid direct contact between the transducer and the fixing block to cause wear. The fixing bolt is installed and rotated to connect the fixing block with the load-bearing block, thereby changing the clamping space between the two. During the downward pressing process of the fixing block, the buffer springs on the outer sides of the two protection pads are compressed. After the fixing is completed, the extrusion force will be reduced under the reaction force of the buffer spring, thereby avoiding damage to the transducer caused by excessive extrusion force. The problem that the transducer is fixed by a fixing clamp, but the transducer will be damaged if the bolts are tightened too tightly, and will shake when used if they are tightened too loosely, thereby affecting normal use is solved.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Specific embodiment 1

[0030] See also Figure 1 , Figure 2 and Figure 3 The utility model is a transducer sealing installation structure of a vibrating screen, including a screen frame 1 and an inner wall of the screen frame 1 with a screen 101 installed, and an outer wall of the screen 101 with a sealing component 2 installed. The sealing component 2 can directly seal and connect the transducer 204 with the screen 101, solving the existing problem that the transducer 204 cannot be directly sealed and connected with the screen 101.

[0031] Specifically, the outer wall of the sealing rubber ring 201 of the sealing assembly 2 is fixedly connected to the connecting column 202, and the connecting column 202 has the effect of connection and positioning. The outer wall of the connecting column 202 is slidingly connected to the sealing ring 203 to facilitate the movement of the sealing ring 203. The sealing rubber ring 201 and the sealing ring 203 can both have a sealing effect. An internal thread is provided on the inner wall of the connecting column 202, and the connecting column 202 is connected to the transducer 204 through the internal thread to facilitate connection.

[0032] Furthermore, a positioning hole 102 is provided on the right side wall of the screen frame 1 to facilitate the passage of the connecting column 202. The screen frame 1 is plugged and connected to the connecting column 202 through the positioning hole 102 to facilitate the installation of the connecting column 202. At the same time, an installation groove 201a is provided on the inner side of the sealing rubber ring 201. The sealing rubber ring 201 wraps the screen 101 through the installation groove 201a to facilitate wrapping and sealing the outside of the screen 101 and facilitate subsequent connection.

[0033] The operation process of this embodiment is: install the screen 101 on the inner side of the sealing rubber ring 201 through the installation groove 201a of the sealing rubber ring 201, and then pass the connecting column 202 through the positioning hole 102 of the screen frame 1 to facilitate the positioning and installation of the sealing rubber ring 201, and then connect the transducer 204 to the connecting column 202 on the outside. After the connection is completed, move the sealing ring 203 to seal and protect the connection between the connecting column 202 and the transducer 204, so as to realize the direct connection between the transducer 204 and the screen 101 through the connecting column 202, so as to achieve a better screening effect during operation. Specific embodiment 2

[0034] See also Figure 1 , Figure 2 and Figure 4 On the basis of the specific embodiment 1, a fixing component 3 is installed on the outer wall of the screen frame 1. The fixing component 3 can fix transducers 204 of different types and can also play a protective role, thereby solving the existing problem that the transducer 204 cannot be protected.

[0035] Specifically, the outer wall of the transducer 204 is wrapped with a protective pad 305 to protect the transducer 204. The outer wall of the transducer 204 is fitted and connected to the protective pad 305 to facilitate the installation of the transducer 204. The protective pad 305 is fixedly connected to the moving end of the buffer spring 304 to facilitate the movement of the protective pad 305. At the same time, the fixed end of the buffer spring 304 is fixedly connected to the load-bearing block 301 to fix the buffer spring 304 so as to achieve a better buffering effect and a better protection effect.

[0036] Furthermore, one end of the upper side wall of the load-bearing block 301 of the fixed component 3 is connected to the fixed block 303 through the rotating shaft 302, which is convenient for the rotation of the fixed block 303. At the same time, the other end of the load-bearing block 301 is connected to the fixed block 303 through the fixing bolt 306, so as to realize the closed connection between the fixed block 303 and the load-bearing block 301. At the same time, the left side wall of the load-bearing block 301 is fixedly connected to the fixing column 307, and the fixing column 307 plays a supporting and fixing effect. The left side wall of the fixing column 307 is fixedly connected to the screen frame 1, so as to realize the effect of connecting the load-bearing block 301 with the screen frame 1.

[0037] The operation process of this embodiment is as follows: rotate the fixed block 303, the fixed block 303 rotates in a circle around the rotating shaft 302, and then the fixed block 303 and the load-bearing block 301 are opened, which is convenient for placing the transducer 204 on the protection pad 305, and then rotate the fixed block 303 until it moves to the top of the fixed block 303. At this time, the two protection pads 305 on the inner wall will wrap the transducer 204 to avoid direct contact between the transducer 204 and the fixed block 303, causing wear, and then install the fixing bolt 306, and rotate the fixing bolt 306 to connect the fixed block 303 with the load-bearing block 301, thereby changing the clamping space between the two. During the downward pressing process of the fixed block 303, the buffer springs 304 on the outside of the two protection pads 305 will be compressed. After the fixing is completed, the extrusion force will be reduced under the reaction force of the buffer spring 304 to avoid the extrusion force being too large to damage the transducer 204.
