[0003] The structure of vibrating screen is generally composed of screen frame, screen, vibrator, inlet and outlet, supporting device and the like, the screen frame of vibrating screen is generally made of steel plate, which can withstand large vibration force; Screen is the core component of vibrating screen, which is composed of screen with different materials and different aperture, which can realize different screening of materials; Vibrator is the main driving force source of vibrating screen, which can make the screen frame vibrate; The inlet is the interface for conveying materials to the vibrating screen, and the outlet is used to output materials with different particle sizes; Supporting device is an auxiliary component of vibrating screen, which can ensure the stable operation of vibrating screen and reduce the noise of vibrating screen.

[0004] At present, most of the vibrating screens use side supporting legs, and springs are arranged between the screen frame and the supporting leg to isolate the kinetic energy transmission between the screen frame and the supporting leg, so as to ensure the stability of the supporting leg when the screen frame vibrates. The current supporting leg adopts an integral welding structure, which cannot adjust the supporting height. When the supporting height error is large during the assembly process of vibrating screen, it will affect the overall balance of the screen frame and increase the risk of accidents during the operation of vibrating screen.

[0005] Therefore, the present application provides a kind of adjustable vibrating screen supporting leg to meet the needs. UTILITY MODEL CONTENTS

[0028] 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.

[0029] Example: Reference Figures 1-5 An adjustable vibrating screen support leg is shown, including a column 1 and a support plate 2. The column 1 is fixed on the base of the vibrating screen. The top and bottom surfaces of the column 1 are parallel to the horizontal plane. The top of the column 1 is vertically provided with studs 11, and there are multiple sets of studs 11 arranged symmetrically.

[0030] The support plate 2 is used to connect the spring to support the screen frame. The support plate 2 is symmetrically provided with through holes 20. There are multiple sets of through holes 20 and they are adapted to the studs 11. The support plate 2 moves up and down along the studs 11.

[0031] Each set of studs 11 is equipped with two sets of adjusting nuts 3, which limit the support plate 2 from the top and bottom directions respectively.

[0032] As one implementation method in this embodiment, to facilitate the installation of the positioning column 1, such as Figures 1 to 3 As shown, column 1 is a rectangular column.

[0033] As one implementation method in this embodiment, to facilitate achieving a stable support effect for the support plate 2, such as Figures 1 to 3 As shown, there are four sets of studs 11, and the studs 11 are located at the four corners of the top surface of the column 1. The support plate 2 has the same shape as the top surface of the column 1, which is rectangular. There are four sets of through holes 20, which are adapted to the studs 11.

[0034] As one implementation method in this embodiment, to reduce the weight of column 1, such as... Figures 1 to 3 As shown, the interior of column 1 is hollow, and column 1 is provided with counterweight holes 10 that are open at the front and back. There are four sets of counterweight holes 10 that are evenly distributed.

[0035] As one implementation method in this embodiment, to facilitate the connection and assembly of the spring to the support plate 2, such as Figure 1 , Figure 2 and Figure 4 As shown, the top surface of the support plate 2 is provided with a spring seat 21. There are two sets of spring seat 21 arranged symmetrically. The spring seat 21 is used to mount the spring.

[0036] As one implementation method in this embodiment, to facilitate the processing of the movable support plate 2, such as Figure 4 As shown, the left and right sides of the support plate 2 are symmetrically provided with hanging ears 22, and each hanging ear 22 is provided with a through ear hole.

[0037] As one implementation method in this embodiment, to enhance the stabilizing effect of the adjusting nut 3 on the support plate 2, such as... Figure 5 As shown, a side screw hole 30 is provided on the side wall of the adjusting nut 3, and a set screw 31 is threaded into the side screw hole 30. The set screw 31 is used to enhance the friction between the adjusting nut 3 and the stud 11.

[0038] As one implementation method in this embodiment, to facilitate the rotation of the set screw 31 and the adjusting nut 3, such as... Figure 5 As shown, the length of the set screw 31 is less than the length of the side screw hole 30, and the outer end of the set screw 31 is provided with a slot.

[0039] The working principle of this practical application is as follows: When assembling the vibrating screen, firstly, by vertically fixing the column 1 to the vibrating screen base, all the support legs are installed and fixed to the predetermined positions on the vibrating screen base. Then, rotating the set screw 31 causes it to move outward in the side screw hole 30, releasing the limiting position between the adjusting nut 3 and the stud 11. Next, rotating the adjusting nut 3 causes it to drive the support plate 2 to rise and fall. The support plate 2 slides along the stud 11 through the through hole 20, ensuring the stability of the support plate 2's movement. Finally, rotating the set screw 31 causes it to press against the stud 11. This increases the friction between the adjusting nut 3 and the stud 11, fixing them in place to prevent the adjusting nut 3 from loosening during the operation of the vibrating screen. Then, the screen frame is hoisted onto the support legs, and the spring seat 21 is fitted onto the bottom of the spring, thus completing the installation of the vibrating screen. The height of each support plate 2 can be adjusted according to the installation of the screen frame. The counterweight hole 10 on the column 1 can reduce the weight of the column 1 without affecting its structural strength, thus facilitating the installation of the support legs. The lugs 22 on both sides of the support plate 2 facilitate the movement and transportation of the support plate 2.
