Description

Technical Field

[0001] This utility model relates to the field of linear screen technology, specifically a novel inclined linear screen. Background Technology

[0002] A vibrating screen is a type of vibrating screening machinery suitable for dry screening of wet, fine-grained, and difficult-to-screen materials. It is currently the most widely used vibrating screening machinery in China for processing difficult-to-screen materials. Vibrating screens have an extremely wide range of applications, involving all aspects of life, with the most typical application being in mineral processing. Invention patent CN103272764A discloses a linear vibrating screen, which includes a screen body with two vibrating motors installed on the upper part of the screen body at a 90-degree angle. This linear vibrating screen has a reasonable structure, good performance, and can effectively improve the screening efficiency.

[0003] Currently, the existing linear vibrating screen motor base is welded to the screen frame, and the screen holder is connected to the side plates by bolts. Since the equipment vibrates at approximately 1000 r / min, which is considered high-frequency vibration, the welded joints are easily damaged during operation, and the bolted connections are prone to loosening, leading to a reduced equipment lifespan. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a new type of inclined linear vibrating screen, which solves the problem that the motor base and screen of the existing linear vibrating screen are easily damaged and loosened due to vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel inclined linear screen, comprising a screen frame, two symmetrically distributed side plates welded to the side of the screen frame, a screen mesh installed between the two side plates by means of ring groove rivets, a motor base installed between the two side plates above the screen mesh by means of ring groove rivets, a vibrating motor fixedly installed on the motor base, connecting ears installed on the outer side of the side plates by means of bolts, a spring fixedly connected to the bottom of the connecting ears, a support leg fixedly connected to the bottom of the spring, a base welded to the bottom of the support leg, and an anti-slip mechanism provided inside the base.

[0006] Preferably, the anti-slip mechanism includes a hollow plate fixedly connected to the inside of the base. A sliding column is slidably connected inside the hollow plate and penetrates through the hollow plate. One end of the sliding column is fixedly connected to an inclined seat, and the other end is fixedly connected to an anti-slip pad. Both the anti-slip pad and the inclined seat are slidably connected inside the base. An adjusting screw is threadedly connected to the side of the base and penetrates through the base. A ball head is fixedly connected to one end of the adjusting screw inside the base, and the ball head abuts against the inclined seat. The anti-slip mechanism increases the friction between the entire structure and the ground, thereby preventing slippage during screen vibration.

[0007] Preferably, a second spring is fitted onto the outer side of the sliding column body. One end of the second spring is fixedly connected to the inclined plate, and the other end of the second spring is fixedly connected to the hollow plate. By providing the second spring, the reaction force can be applied to the inclined plate.

[0008] Preferably, a knob is fixedly connected to one end of the adjusting screw located outside the base, and the knob and the adjusting screw are an integral structure. The knob facilitates the turning of the adjusting screw.

[0009] Preferably, the top of the inclined seat is provided with an inclined surface that abuts against the ball head. By providing the inclined surface, the lateral thrust from the ball head can be converted into a vertical compressive force.

[0010] Preferably, the anti-slip mat is rectangular in shape and made of rubber. Rubber anti-slip mats have good friction.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses grooved rivets to install the original motor base and the original screen. The grooved rivet connection is a type of locking bolt that will never loosen, also known as "cold riveting". It has the characteristics of high connection strength, good anti-vibration and anti-loosening effect, and simple and quick installation, thereby avoiding the motor base and screen from loosening or breaking due to long-term vibration.

[0013] 2. This utility model provides an anti-slip mechanism within the base of the device. By turning the knob to adjust the screw, the screw moves laterally through the threaded movement between itself and the base. The ball end of the adjusting screw pushes the inclined seat, subjecting it to downward pressure. This pressure is then transferred to the anti-slip pad via a sliding column, increasing the friction between the anti-slip pad and the ground and preventing slippage during screen vibration.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A novel inclined linear screen includes a screen frame 1. Two symmetrically distributed side plates 2 are welded to the side of the screen frame 1. A screen 5 is installed between the two side plates 2 by means of ring groove rivets. A motor base 3 is installed between the two side plates 2 above the screen 5 by means of ring groove rivets. A vibration motor 4 is fixedly installed on the motor base 3. A connecting ear 6 is installed on the outer side of the side plate 2 by means of bolts. A spring 7 is fixedly connected to the bottom of the connecting ear 6. A support leg 8 is fixedly connected to the bottom of the spring 7. A base 10 is welded to the bottom of the support leg 8.

[0020] Please see Figure 1-3The base 10 is equipped with an anti-slip mechanism 9. This mechanism increases the friction between the screen and the ground, preventing slippage during vibration. The anti-slip mechanism 9 includes a hollow plate 91 fixedly connected inside the base 10. A sliding column 92 is slidably connected inside the hollow plate 91, penetrating the plate. One end of the sliding column 92 is fixedly connected to an inclined seat 94, and the other end is fixedly connected to an anti-slip pad 93. Both the anti-slip pad 93 and the inclined seat 94 are slidably connected inside the base 10. The top of the inclined seat 94 has an inclined surface that abuts against a ball head 97. This inclined surface converts the lateral thrust from the ball head 97 into a vertical compressive force. The anti-slip pad 93 is a rectangular block made of rubber. The rubber anti-slip pad 93 has good friction. A second spring 95 is fitted on the outer side of the main body of the sliding column 92. One end of the second spring 95 is fixedly connected to the inclined plate 94, and the other end of the second spring 95 is fixedly connected to the hollow plate 91. By setting the second spring 95, the reaction force can be applied to the inclined plate 94.

[0021] Please see Figure 2 An adjusting screw 96 is threadedly connected to the side of the base 10, and the adjusting screw 96 passes through the base 10. A ball head 97 is fixedly connected to the end of the adjusting screw 96 inside the base 10, and the ball head 97 abuts against the inclined seat 94. A knob 98 is fixedly connected to the end of the adjusting screw 96 outside the base 10, and the knob 98 and the adjusting screw 96 are an integral structure. The knob 98 facilitates the turning of the adjusting screw 96.

[0022] The specific implementation process of this utility model is as follows: In use, the whole unit is placed on the ground, and then the adjusting screw 96 is turned by the knob 98. The adjusting screw 96 moves laterally through the threaded movement between it and the base 10. The ball head 97 at the end of the adjusting screw 96 pushes the inclined seat 94, so that the inclined seat 94 is subjected to downward squeezing force. The inclined seat 94 then applies the squeezing force to the anti-slip pad 93 through the sliding column 92. This increases the friction between the anti-slip pad 93 and the ground, preventing the device from slipping when vibrating the screen. In addition, the original motor base 3 is installed with ring groove rivets, and the original screen 5 is also installed with ring groove rivets. The ring groove rivet connection is a kind of locking bolt that never loosens, also known as "cold riveting". It has the characteristics of high connection strength, good anti-vibration and anti-loosening effect, and simple and quick installation, thereby avoiding the motor base 3 and screen 5 from loosening or breaking due to long-term vibration.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
