Description

Technical Field

[0001] The utility model relates to the technical field of vibration screen equipment, and more specifically to a stabilizing mechanism of a linear vibration screen. Background Art

[0002] As a common screening equipment, the main principle of vibrating screen is to use the vibration of the vibrating screen to screen and classify the materials on its screen holes. Linear vibrating screen is a type of vibrating screen. It is rectangular with stabilizing mechanisms installed on the four corners. The stabilizing mechanisms are connected to the base through elastic elements (such as metal springs or rubber springs). Such a suspension design can effectively absorb vibration energy and reduce vibration transmission. At the same time, it allows the screen box to move with a certain degree of freedom, which improves the stability of the equipment and reduces noise.

[0003] The discharge pipe of the linear vibrating screen will be set lower than the feed port, so that it has a certain angle to facilitate better discharge. The angle of the vibrating screen can speed up the movement of the material in the vibrating screen and improve its movement efficiency. At the same time, the inclination angle can amplify the vibration effect generated by the vibration source, so that the throwing movement of the material on the screen surface is more effective. Different inclination angles have different effects, such as accurately controlling the residence time of the material and increasing the material processing volume per unit time. However, the angles of most vibrating screens are fixed and not convenient to adjust. Although there are also stabilizing mechanisms that can adjust the vibrating screen, such as the Chinese patent with application number 201921839432.6, a vibrating screen angle adjustment structure and a screening machine having the same are disclosed. The structure includes: an adjustment base, provided with a mounting surface; a plurality of adjustment motors, which are provided and installed on the adjustment base, the adjustment motor is connected to the mounting surface, and a grading adjustment rod is connected to the adjustment motor; a first bracket, the first bracket includes a first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate are connected by an angle compensation plate, the first mounting plate is installed on the vibrating screen, and the second mounting plate is installed on the upper end of the grading adjustment rod. Although the vibration screen angle adjustment structure and the screening machine having the same have the function of adjusting the height, when the stabilizing mechanism is adjusted in height, the front stabilizing mechanism will be stretched upward, thereby affecting the effect of the front stabilizing mechanism when vibrating. Moreover, when the rear stabilizing mechanism is adjusted in height, since the bottom of the bottom adjustment is fixed and the angle of the vibration screen becomes larger, the top of the stabilizing mechanism being adjusted will be tilted, thereby affecting the effect during screening. At the same time, when adjusting the height, multiple adjusting motors are required to perform synchronous actions, which will not only increase production costs but also increase maintenance time.

[0004] Therefore, it is necessary to propose a stabilizing mechanism for a linear vibrating screen to solve the above problems. Utility Model Content

A guide groove is provided inside the fixed rod 103, so that the lifting rod 105 can only move up and down, and will not rotate with the rotation of the threaded rod 104. The fixed rod 103 is internally rotatably connected with the threaded rod 104 extending into the interior of the cross bar 102. The lifting rod 105 is driven up and down by the rotation of the threaded rod 104. The top of the threaded rod 104 is threadedly connected with the lifting rod 105, the top of the lifting rod 105 is connected with a stabilizing component 106, and the top of the stabilizing component 106 is connected with a connecting component 107;

[0029] refer to Figure 3The connecting assembly 107 includes a slide rail 108 and a connecting block 109. The connecting assembly 107 is used to connect the stabilizing assembly 106 and the vibrating screen. The connecting block 109 is connected to the top of the stabilizing assembly 106. The slide rail 108 is connected to the outer wall of the linear vibrating screen. When one side of the vibrating screen is raised, according to the Pythagorean theorem, the connection point at the top of the side will move. The connecting block 109 sliding on the slide rail 108 can change the connection position according to the lifting situation. The slide rail 108 is axially slidably connected with a sliding block 110. The internal rotation of the connecting block 109 is connected with a rotating rod 111. When one side of the vibrating screen is raised, the rotating rod 111 will rotate in the connecting block 109. One end of the rotating rod 111 is connected to the sliding block 110.

[0030] refer to Figure 2 and Figure 4 A cavity 112 is provided inside the rotating rod 111, and an adjusting rod 113 is axially movable in the cavity 112. After the adjusting rod 113 is inserted into the circular hole 120, the sliding block 110 can be fixed on the sliding rail 108 to prevent the sliding block 110 from moving back and forth during use. A threaded baffle 114 is connected to the cavity 112, and a threaded portion 115 threadedly connected to the threaded baffle 114 is provided on the outer wall of the adjusting rod 113;

[0031] Specifically, refer to Figure 2 and Figure 4 The threaded portion 115 and the annular groove 118 are adjacent. When the plug rod 119 is inserted into the circular hole 120, the threaded baffle 114 will be located in the annular groove 118. Since the outer annular surface of the annular groove 118 is smaller than the thread of the inner annular surface of the threaded baffle 114, it will not contact the threaded baffle 114. A circular plate 116 is connected to the outer wall of the adjustment rod 113. A spring 117 is provided between the circular plate 116 and the threaded baffle 114. The circular plate 116 is fixed to the adjustment rod 113. On the rod 113, the plug rod 119 can be inserted into the circular hole 120 through the push of the spring 117 on one side. The outer ring surface of the circular plate 116 is smaller than the diameter of the cavity 112, so it can move axially in the cavity 112. The outer wall of the adjustment rod 113 is provided with an annular groove 118 connected to the threaded portion 115. The outer ring surface of the annular groove 118 is smaller than the inner thread surface of the threaded baffle 114. One end of the adjustment rod 113 is connected to the plug rod 119;

[0032] When unlocking, pull the adjusting rod 113 to pull the plug rod 119 out of the circular hole 120. At this time, the spring 117 between the threaded baffle 114 and the circular plate 116 is compressed. At this time, the threaded portion 115 on the adjusting rod 113 will move to a position in contact with the threaded baffle 114. At this time, rotate the adjusting rod 113 to fix the adjusting rod 113 on the threaded baffle 114 through the thread, and then the height can be adjusted.

[0033] refer to Figure 2 One end of the plug-in rod 119 can extend out of the sliding block 110 and contact the slide rail 108. A circular hole 120 is provided on the slide rail 108 to accommodate the insertion of the plug-in rod 119. The size of the circular hole 120 corresponds to the plug-in rod 119. The axes of the circular holes 120 are arrayed on the slide rail 108. Multiple circular holes 120 can be staggered and not completely overlapped to reduce the distance between two circular holes 120.

[0034] Specifically, refer to Figure 3 The bottom of the threaded rod 104 is connected to a worm wheel 121, and the internal rotation of the cross bar 102 is connected to a driving rod 122. By rotating the driving rod 122, the driving rod 122 drives the worm 123 to rotate, and the threaded rod 104 is driven to rotate through the threaded connection between the worm 123 and the worm wheel 121. The two ends of the driving rod 122 extend out of the cross bar 102, and the two ends of the driving rod 122 are connected to the worm 123 that is transmission-connected to the worm wheel 121. The two ends of the worm 123 are sleeved with rotating handles, and the rotating handles are convenient for users to grasp.

[0035] Specifically, refer to Figure 3 The stabilizing component 106 includes two upper special-shaped plates 124 and a lower special-shaped plate 125 of different sizes. As shown in the figure, multiple groups of elastic components 126 are arranged between the upper special-shaped plate 124 and the lower special-shaped plate 125 to improve the stability of the screen body during vibration and reduce the vibration of the support frame 101 transmitted to the bottom. An elastic component 126 is arranged between the upper special-shaped plate 124 and the lower special-shaped plate 125.

[0036] Specifically, the elastic component 126 is composed of a spring 117 and a rubber support ring.

[0037] Specifically, refer to Figure 2 and Figure 4 The end of the adjustment rod 113 away from the plug rod 119 extends out of the rotating rod 111, and a rotating handle is connected to the rotating handle, which is convenient for users to grasp. When pulled, the spring 117 in the cavity 112 will be compressed.

[0038] Specifically, refer to Figure 1 The support frame 101 also includes a vertical rod 127, which is used to connect the two fixing rods 103 to enhance the stability of the bottom. The vertical rod 127 is used to connect the two fixing rods 103.

[0039] In this embodiment, a stabilizing component 106 is connected between the support frame 101 and the linear vibrating screen. The stabilizing component 106 plays a shock-absorbing role, which can effectively absorb the vibration energy generated by the vibrating screen during operation and reduce the dynamic load transmitted to the foundation by the vibration, thereby protecting the machine itself and the surrounding buildings from damage, reducing noise, and extending the service life of the equipment. At the same time, it is also used to support the weight of the entire screen box, ensuring that the screen box can be stably suspended on the support frame 101 and can maintain a good working condition even during long-term vibration work.

[0040] When the height of one side of the vibrating screen needs to be adjusted, the adjusting rod 113 is first pulled outward, so that the plug-in rod 119 on one side of the adjusting rod 113 is pulled out from the circular hole 120, and the spring 117 between the threaded baffle 114 and the circular plate 116 is compressed, and the threaded portion 115 moves to a position in contact with the threaded baffle 114. At this time, the adjusting rod 113 is rotated to fix the adjusting rod 113 on the threaded baffle 114 through the thread, and the sliding block 110 can slide freely on the slide rail 108;

[0041] The rotating handle on one side of the crossbar 102 is turned to drive the driving rod 122 to rotate through the handle. The driving rod 122 is meshed with the worm 123 through the external worm gear 121, thereby driving the threaded rod 104 to rotate. When the threaded rod 104 rotates, it can drive the lifting rod 105 to rise and fall, and can adjust the height of the top stabilizing assembly 106, thereby adjusting the height of one side of the vibrating screen;

[0042] After the plug-in rods 119 on the four sides of the vibrating screen are pulled out from the circular holes 120 and the height of one side of the vibrating screen is adjusted, the rotating rod 111 on the other side can automatically rotate in the connecting block 109 to adapt to the rotation of the vibrating screen. After the height is adjusted, the adjusting rod 113 is rotated in the opposite direction to reset the adjusting rod 113 so that the plug-in rod 119 can be reinserted into the circular hole 120 to complete the connection and fixation of the sliding block 110 and the slide rail 108.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
