Description

Technical Field

[0001] This utility model relates to the technical field of vibrating screening devices, specifically a vibrating screening device for sand screening. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together into a whole by cementing materials. It is usually made by mixing sand and gravel as aggregates with water (which may contain admixtures and additives) in a certain proportion and then mixing them to obtain cement concrete. Sand and gravel refer to a loose mixture of sand and crushed stone. Due to their good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials or concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. When sand and gravel are used in concrete production, they need to be screened because of their different sizes. Vibrating screens are industrial equipment that uses mechanical vibration to classify and filter materials. Their core principle is to drive the screen surface to generate a specific motion trajectory through a vibrator, so that the material can complete the dispersion, stratification and screening process on the screen. The springs in the vibrating screen need to be replaced during long-term use. Currently, because the springs are fixed by a tight compression method, they may suddenly pop out when the compression is released during replacement, causing a safety hazard.

[0003] Therefore, we propose a vibrating screening device for sand screening. Utility Model Content

[0013] 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.

[0014] Example Please see Figures 1-3The diagram shows a vibrating screen for sand screening, including a vibrating screen body 1. The vibrating screen body 1 is fixedly connected to a spring upper support plate 2. The spring upper support plate 2 tightly presses against a spring 3. The spring 3 is connected to a spring adjustment mechanism 4 for adjusting the spring. The spring adjustment mechanism 4 is fixedly connected to a lower support plate 5. This utility model uses the spring upper support plate to fixally connect the spring adjustment mechanism. The spring adjustment mechanism includes an upper support, a lower support, a cylinder, a spring 2, a main adjustment rod, a secondary adjustment rod, a locking adjustment rod, a locking connecting block, a snap ring, and a connecting rod. The connecting rod tightly presses against the spring, thereby effectively solving the problem that the spring may suddenly pop out when the pressure is released, causing a safety hazard. At the same time, it facilitates the installation and disassembly of the spring.

[0015] Furthermore, the spring adjustment mechanism 4 includes an upper bracket 401, a lower bracket 402, a cylinder 403, a second spring 404, a main adjustment rod 405, a secondary adjustment rod 406, a locking adjustment rod 407, a locking connecting block 408, a snap ring 409, and a connecting rod 410. The upper bracket 401 is slidably connected to the lower bracket 402, and the upper bracket 401 is fixedly connected to the upper spring bracket plate 2. The spring adjustment mechanism facilitates the adjustment of the spring and can move up and down with the spring.

[0016] Furthermore, the lower bracket 402 is fixedly connected to the cylinder 403, and the lower bracket 402 is fixedly connected to the lower bracket plate 5. The lower bracket is fixedly connected to the cylinder, and the lower bracket is slidably connected to the upper bracket, thereby ensuring the stability of the spring adjustment mechanism.

[0017] Furthermore, the main adjusting rod 405 is rotatably connected inside the cylinder 403. The main adjusting rod 405 is equipped with a second spring 404. The main adjusting rod 405 is inserted into and cooperates with the secondary adjusting rod 406. The cylinder 403 is equipped with two retaining rings 409. The main adjusting rod, the secondary adjusting rod and the retaining rings are provided inside the cylinder, thereby limiting the position of the main adjusting rod and the secondary adjusting rod by the retaining rings.

[0018] Furthermore, the main adjusting rod 405 is threadedly connected to the locking adjusting rod 407, and the locking adjusting rod 407 is rotatably connected to the locking connecting block 408. The locking adjusting rod is threadedly connected to the main adjusting rod, thereby ensuring the adjustment of the spring by the locking adjusting rod.

[0019] Furthermore, the locking connecting block 408 is connected to the connecting rod 410, which tightly presses against the spring 3. Both ends of the connecting rod 410 are fixedly connected to the locking connecting block 408. The two connecting rods are connected through the locking connecting block, and the connecting rods pass through the spring and are fixedly connected to the locking connecting block, thereby ensuring the stability of the spring pressing.
