Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screen equipment, and more specifically to a material collecting device of a linear vibrating screen. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

[0003] The vibrating screen is provided with two or more discharge pipes for discharging the separated materials. Since the vibrating screen is in a vibrating state when working, a certain distance is usually maintained between the discharge pipe and the storage device, but this will cause the dust generated during screening to float around. Chinese patent application number 201921982305.1 discloses a collection device for a linear vibrating screen, which includes a discharge pipe, a telescopic tube and a collection hopper. The discharge pipe is used for discharging materials, one end of the telescopic tube is connected to the discharge pipe, and the other end of the telescopic tube is detachably connected to the inner wall of the collection hopper, and the collection hopper is used to collect materials. The material collecting device of the linear vibrating screen avoids the situation where dust is scattered everywhere by adding a telescopic tube to the discharge pipe. At the same time, it can avoid the situation where noise is generated when the discharge pipe contacts the material collecting device. However, since the vibrating screen is always in a vibrating state when working, the bottom of the telescopic tube is fixed, and the top vibrates with the vibrating screen, which greatly shortens the life of the telescopic tube and requires frequent replacement of the telescopic tube. The device only has a structure for quickly disassembling the bottom of the telescopic tube and the material collecting hopper, and the top of the telescopic tube is connected to the discharge pipe. It lacks a structure that can be quickly disassembled, and it is not convenient to remove the worn telescopic tube from the vibrating screen.

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

To achieve the function of clamping and fixing, the bottom of the fixed sleeve 104 is fixedly connected to a bottom support plate 105, and a plurality of clamping claws 106 are rotatably connected to the outer wall of the bottom support plate 105. The clamping claw 106 is L-shaped, and the bending part is the axis of rotation. A sliding groove 111 is provided on the top, and an anti-sliding block 107 is connected to the bottom. A plurality of clamping claws 106 are equidistantly arranged on the bottom support plate 105. The bottom of the clamping claw 106 is connected to an anti-sliding block 107 on the side close to the discharge pipe 102. The anti-sliding block 107 is made of anti-slip rubber, and an anti-slip stripe is provided on the side close to the telescopic tube 103. The clamping claw 106 fixes the top of the telescopic tube 103 to the outer wall of the discharge pipe 102 through the anti-sliding block 107.

[0032] refer to Figures 2 to 5 A threaded sleeve 108 is rotatably connected to the outer wall of the fixed sleeve 104. A thread is provided on the outer wall of the threaded sleeve 108, and a lifting ring 109 is connected to the thread through the thread. The threaded sleeve 108 rotates on the outer wall of the fixed sleeve 104, and the top is fixedly connected to the spline block 113. The lifting ring 109 is connected to the outer wall through the thread. A driving frame 110 is arrayed on the outer wall of the lifting ring 109. A sliding groove 111 is provided on the top of the clamping jaw 106. The clamping jaw 106 is driven to open and close by moving the rotating rod 112 up and down in the sliding groove 111. The internal rotation of the driving frame 110 is connected to the rotating rod 112 that moves in the sliding groove 111.

[0033] refer to Figures 2 to 5The top of the threaded sleeve 108 is connected with a spline block 113, and the spline block 113 is spline-connected with a hand-held collar 114. The hand-held collar 114 can slide up and down on the outer wall of the spline block 113. The outer wall of the spline block 113 is spline-connected with the hand-held collar 114. A cavity 115 is provided inside the hand-held collar 114. The cavity 115 is located between the hand-held collar 114 and the spline block 113. When the hand-held collar 114 moves upward, the cavity 115 15 becomes larger, when the hand-held collar 114 moves downward, the cavity 115 becomes smaller, and the internal spring 116 will be compressed at the same time. The spring 116 is sleeved in the cavity 115, and the top of the hand-held collar 114 is provided with an inner spline groove 117. The top of the fixed sleeve 104 is provided with an outer spline portion 118 that cooperates with the inner spline groove 117. When the outer spline portion 118 is inserted into the inner spline groove 117, the hand-held collar 114 will be restricted to prevent it from rotating;

[0034] refer to Figure 3 A guide rod 119 is provided between two adjacent driving frames 110. The guide rod 119 is used to stabilize the rise and fall of the lifting ring 109 so that the lifting ring 109 can only move up and down. The bottom of the guide rod 119 is fixed on the bottom support plate 105. The top of the guide rod 119 is connected to the top support plate 120. The top support plate 120 is used to support the tops of multiple guide rods 119. The lifting ring 109 is slidably connected to the guide rod 119.

[0035] Specifically, refer to Figure 7 A convex ring 121 is provided on the outer wall of the bottom of the telescopic tube 103, and the positions of the convex ring 121 and the compression chamber 122 correspond to each other. When the anti-sliding block 107 is pressed on the telescopic tube 103, the convex ring 121 will squeeze the compression chamber 122, causing the compression chamber 122 to be concave inward, and then the outer wall of the anti-sliding block 107 will wrap the top and bottom of the convex ring 121 to increase the contact area, and the interior of the anti-sliding block 107 is provided with a compression chamber 122 corresponding to the position of the convex ring 121.

[0036] Specifically, refer to Figure 4 The bottom of the bottom support plate 105 is connected with a sealing rubber ring 123 , and the sealing rubber ring 123 is located between the bottom support plate 105 and the telescopic tube 103 to increase the sealing performance of the connection, and the top of the telescopic tube 103 is in contact with the sealing rubber ring 123 .

[0037] Specifically, refer to Figure 3 The top of the fixed sleeve 104 is connected with a limit ring 124, which plays a limiting role and prevents the hand-held sleeve 114 from moving excessively upward.

[0038] Specifically, refer to Figure 7 The clamping claw 106 is L-shaped, and is rotatably connected to the bottom support plate 105 at the bend.

[0039] In this embodiment, the vibration screen body 101 is a vibration screening device, and the material to be screened is added to the device from the feed port on the top of the vibration screen body 101. A screen is installed in the vibration screen body 101, and a vibration motor for generating vibration is installed at the bottom. Under the action of vibration, the material on the screen surface is subjected to continuous throwing and sliding, and the particles jump forward on the screen surface, and collide and rub with the screen holes at the same time. The particles larger than the size of the screen hole cannot pass through the screen hole and remain on the screen surface and continue to move forward, and are finally discharged from the corresponding discharge port, that is, the screen material, and the particles smaller than the size of the screen hole smoothly pass through the screen hole and flow out from the corresponding screen material outlet, so as to achieve particle size separation. The discharge port of the vibration screen body 101 is connected with a discharge pipe 102, and the bottom of the discharge pipe 102 is sleeved with a telescopic pipe 103, which is connected to a collecting device through the telescopic pipe 103, so that the telescopic pipe 103 can be quickly replaced after it is worn;

[0040] The telescopic tube 103 is sleeved on the bottom of the discharge pipe 102, and the top is against the bottom support plate 105, and a sealing rubber ring 123 is arranged between them to increase the sealing of the connection and prevent dust from escaping. The multiple clamping claws 106 at the bottom of the fixed sleeve 104 play a role of clamping and fixing the top of the telescopic tube 103 to fix it on the discharge pipe 102;

[0041] When it is necessary to replace a new telescopic tube 103, the hand-held collar 114 is held and pulled downward. At this time, the inner spline groove 117 on the top of the hand-held collar 114 is separated from the outer spline portion 118, and the outer spline portion 118 loses its restrictive effect on the hand-held collar 114. The cavity 115 and the spring 116 inside the hand-held collar 114 are compressed, and the hand-held collar 114 moves downward along the outer wall of the spline block 113. At this time, the spline block 113 can be rotated synchronously by rotating the hand-held collar 114. When the spline block 113 rotates, it will drive the threaded sleeve 108 at the bottom to rotate. The threaded sleeve 108 is connected by threads, driving the lifting ring 109 on the outer wall to rise. The lifting ring 109 drives the driving frame 110 of the circumferential array on the outer wall to rise together. When the driving frame 110 rises, the rotating rod 112 will move in the sliding groove 111 of the clamping jaw 106, thereby driving the bottom of the clamping jaw 106 to open outward. After the clamping jaw 106 is opened, the clamping effect on the top of the telescopic tube 103 is lost, so that the broken telescopic tube 103 can be disassembled and replaced with a new one. Then, the hand-held ring 114 is rotated in the reverse direction, and the threaded sleeve 108 drives the lifting ring 109 to move downward, and the rotating rod 112 will move downward in the sliding groove 111, thereby driving the clamping jaw 106 to clamp the telescopic tube 103, and the replacement of the telescopic tube 103 can be completed.

[0042] After the replacement is completed, the spring 116 is reset upward, thereby pushing the hand-held collar 114 to move upward, so that the inner spline groove 117 on the hand-held collar 114 is sleeved on the outer side of the outer spline portion 118, and the fixed sleeve 104 fixes the hand-held collar 114 through the outer spline portion 118, and then the hand-held collar 114 is connected to the spline of the bottom spline block 113 through the spline, so as to limit its rotation, and the guide rod 119 plays a guiding role, so that the lifting ring 109 can only move up and down;

[0043] The anti-slip block 107 is provided with anti-slip stripes on the top to increase the anti-slip ability, and a compression chamber 122 is provided inside. When the telescopic tube 103 is completely sleeved on the bottom of the discharge tube 102, the height of the compression chamber 122 corresponds to the position of the convex ring 121. When the anti-slip block 107 is pressed on the telescopic tube 103, the internal compression chamber 122 will be compressed, thereby increasing the contact area between the anti-slip block 107 and the convex ring 121 to increase the stability during connection.

[0044] 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.
