Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, and in particular relates to a vibrator for a swing screen that is easy to install. Background Technology

[0002] The gyratory screen is a high-performance precision screening device. Its design concept is to simulate the efficient and gentle movements of manual screening. It is very suitable for processing fragile, easily abrasive, flaky, elongated, or difficult-to-screen materials that are close to the screen aperture size, as well as for applications requiring high-precision grading. It is widely used in industries such as chemical, food, pharmaceutical, metal powder, ceramics, and recycled resources. The vibrator is the core power source and "heart" that provides this unique motion for the gyratory screen. Through its ingenious mechanical design, it transforms simple rotational motion into complex motion that best meets the requirements of efficient and high-precision screening processes. Thus, it plays an irreplaceable role in protecting materials, improving screening efficiency and accuracy, and reducing maintenance costs.

[0003] A search revealed that CN217726236U, with an application date of June 29, 2022, discloses a square gyratory screen vibrator, which includes a vibrator housing, a rotating shaft rotatably disposed inside the vibrator housing, and a pulley fixedly disposed on the rotating shaft. A guide rail is disposed on the rotating shaft, a lead screw is rotatably disposed inside the guide rail, and a counterweight is slidably disposed inside the guide rail via the lead screw. An adjustment mechanism for driving the counterweight to slide is disposed inside the rotating shaft.

[0004] However, it still has the following drawbacks in practical use:

[0005] The existing vibrating screen vibrator requires repeated installation of bolts and nuts during installation, which is cumbersome, time-consuming, and labor-intensive, resulting in low installation efficiency.

[0006] 2. Existing vibratory screen exciters require workers to lift them to a certain height for installation and disassembly, which increases the workload of the workers. Therefore, we provide a more conveniently installed vibratory screen exciter to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a vibratory screen exciter that is easy to install. By setting the installation components, four nuts can be simultaneously fitted onto the outer wall of the corresponding screw, eliminating the need to install the four nuts individually and repeatedly, thus improving the installation efficiency of the exciter housing. Furthermore, by using the sliding frame and sliding components, the front part of the sliding frame is tilted downward and in contact with the ground, thereby reducing the height that the exciter housing is lifted during installation and reducing the labor intensity of the workers.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a vibrator for easy installation of a swing screen, including a hanger and hanging plates fixed to the front and rear ends of its two side walls. A sliding frame is slidably arranged inside the hanger. Front support plates are fixed to the front ends of the top two sides of the sliding frame, and rear support plates are fixed to the rear ends of the top two sides of the sliding frame. A sliding component is arranged inside the hanger, and an installation component is arranged on the upper surface of the sliding frame.

[0010] The sliding assembly includes a support plate fixed on the inner walls of both sides of the hanger, and a rotating groove set in the middle of the upper surface of the support plate. The rotating groove is equipped with rotating rollers that are evenly spaced from front to back.

[0011] The mounting components include a knob located at the front end below the slide, and a pivot fixed at the center of the top of the knob.

[0012] The present invention is further configured such that strip grooves are provided on both inner walls of the hanger, a push-pull rod is installed at the bottom front end of the sliding frame, and a sliding rod is fixed on the outer wall of the rear support plate.

[0013] The present invention is further configured such that the other end of the slide rod is slidably inserted into the interior of an adjacent strip groove, and both ends of the sliding frame are fixed with load-bearing plates, and the surface of the load-bearing plates is fitted with a vibrator housing.

[0014] The present invention is further provided in that the front and rear end faces of the vibrator housing are both fixed with connecting seats, and a hexagonal groove is provided at the top center of the connecting seat, and a nut is placed inside the hexagonal groove.

[0015] The present invention is further configured such that the top end of the rotating shaft passes through the bearing on the sliding frame and is connected to the driving gear disk, and a timing belt is fitted on the outer wall of the driving gear disk, with driven gear disks meshing at the four corners inside the timing belt.

[0016] The present invention is further configured such that a connecting ring is fixedly provided on the top of the driven gear plate, and the top end of the connecting ring is rotatably mounted on the bottom of the adjacent front support plate and the rear support plate.

[0017] The present invention is further configured such that a screw is fixed at the top center of the driven gear plate, and the top end of the screw passes through the bearings on the adjacent front support plate and rear support plate and is placed inside the hexagonal groove.

[0018] This utility model has the following beneficial effects:

[0019] This invention, by setting up an installation component, allows four nuts to be simultaneously fitted onto the outer wall of the corresponding screw, eliminating the need for repeated installation of the four nuts individually. This improves the installation efficiency of the vibrator housing and solves the problem that existing vibrating screen vibrators require repeated installation of bolts and nuts, which is cumbersome, time-consuming, and labor-intensive, resulting in low installation efficiency.

[0020] This invention, by setting up a sliding frame and sliding components, allows the front part of the sliding frame to tilt downwards and contact the ground, thereby reducing the height that the vibrator housing needs to be lifted during installation, reducing the labor intensity of workers, and solving the problem that existing vibrating screen vibrators require workers to lift the vibrator to a certain height for installation and disassembly, which increases the labor intensity of workers due to the relatively high installation height.

Detailed Implementation

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] Please see Figures 1 to 4 This utility model is a vibrator for easy installation of a swing screen, including a hanger 100 and hanging plates 101 fixed to the front and rear ends of its two side walls. A sliding frame 103 is slidably arranged inside the hanger 100. Front support plates 104 are fixed to the front ends of the top two sides of the sliding frame 103, and rear support plates 105 are fixed to the rear ends of the top two sides of the sliding frame 103. A sliding assembly 200 is arranged inside the hanger 100. The sliding assembly 200 includes a support plate 201 fixed to the inner walls of both sides of the hanger 100, and a rotating groove 201a arranged in the middle of the upper surface of the support plate 201. Rotating rollers 202 are rotatably installed in the rotating groove 201a at even intervals from front to back.

[0031] Specifically, the inner walls of both sides of the hanger 100 are provided with strip grooves 102, the bottom front end of the sliding frame 103 is equipped with a push-pull rod 103a, and the outer wall of the rear support plate 105 is fixed with a slide rod 105a; the other end of the slide rod 105a is slidably inserted into the interior of the adjacent strip groove 102, the two ends of the interior of the sliding frame 103 are fixed with load-bearing plates 103b, and the surface of the load-bearing plate 103b is equipped with a vibrator housing 106; the front and rear end faces of the vibrator housing 106 are fixed with connecting seats 106a, the top center of the connecting seat 106a is provided with a hexagonal groove 106b, and a nut 106c is placed inside the hexagonal groove 106b.

[0032] Furthermore, the hanger 100 is installed at the bottom of the gyratory screen via the hanger plate 101 and bolts. Two front support plates 104 and two rear support plates 105 are provided, and the front support plates 104 and the rear support plates 105 are arranged symmetrically. The rotating roller 202 can assist the sliding frame 103 in moving. Under the action of the sliding rod 105a and the strip groove 102, the sliding frame 103 can be limited and guided. After the force on the front of the sliding frame 103 disappears, it can rotate around the sliding rod 105a as the center to tilt the sliding frame 103. The nut 106c can be stably placed inside the hexagonal groove 106b.

[0033] The operation process of this embodiment is as follows: After the vibrator housing 106 is installed on the surface of the sliding frame 103, the sliding frame 103 is lifted by the push-pull rod 103a and placed horizontally. Then, under the action of the slide rod 105a and the strip groove 102, and with the cooperation of the rotating roller 202 inside the support plate 201, the sliding frame 103 is pushed into the hanger 100. The same applies when disassembling. After the sliding frame 103 is pulled out, the sliding frame 103 rotates around the slide rod 105a as the center, so that the front part of the sliding frame 103 tilts and falls to the ground, thereby reducing the height of the vibrator housing 106 during installation and reducing the labor intensity of the workers. Example 2

[0034] Please see Figure 4 and Figure 5 Based on Embodiment 1, unlike the first embodiment, an installation component 300 is provided. The installation component 300 includes a knob 301 located at the front end below the sliding frame 103, and a rotating shaft 302 fixed at the center of the top of the knob 301. This solves the problem that existing vibrating screen vibrators require repeated installation of bolts and nuts, which is cumbersome, time-consuming, and labor-intensive, resulting in low installation efficiency.

[0035] Specifically, the top end of the rotating shaft 302 passes through the bearing on the sliding frame 103 and is connected to the driving gear 303. A synchronous belt 304 is sleeved on the outer wall of the driving gear 303. A driven gear 305 is engaged at each of the four corners inside the synchronous belt 304. A connecting ring 305a is fixedly installed on the top of the driven gear 305. The top end of the connecting ring 305a is rotatably installed at the bottom of the adjacent front support plate 104 and rear support plate 105. A screw 306 is fixedly installed at the center of the top of the driven gear 305. The top end of the screw 306 passes through the bearing on the adjacent front support plate 104 and rear support plate 105 and is placed inside the hexagonal groove 106b.

[0036] Furthermore, the knob 301 and the drive gear 303 are installed at both ends of the rotating shaft 302, and the three move synchronously. Under the action of the synchronous belt 304, the drive gear 303 and the four driven gears 305 can rotate synchronously, and the connecting rod plays a role in limiting the rotation of the driven gears 305.

[0037] The operation process of this embodiment is as follows: When the vibrator needs to be installed, the vibrator housing 106 is placed on the surface of the load-bearing plate 103b, and the corresponding screw 306 is inserted into the hexagonal groove 106b on the corresponding connecting seat 106a. Then, nuts 106c are placed into multiple hexagonal grooves 106b in sequence. When it is necessary to screw the nuts 106c to the screw 306, since the nuts 106c can be stably locked in the hexagonal grooves 106b, pressure is applied to the four nuts 106c simultaneously, so that the nuts 106c are stably pressed against the top of the screw 306. Then, the knob 301 is rotated. The knob 301 is driven by force to rotate the shaft 302 and the active gear 303 at its top synchronously. The outer wall of the active gear disk 303 meshes with the four driven gear disks 305 through the synchronous belt 304. Therefore, the rotation of the active gear disk 303 will drive the four driven gear disks 305 to rotate synchronously under the action of the synchronous belt 304. The rotation of the driven gear disks 305 will drive the screw 306 to rotate under the limiting action of the connecting ring 305a. The external thread on the outer wall of the screw 306 is helically engaged with the nut 106c. Therefore, the rotation of the screw 306, combined with the vertical pressure and horizontal limiting action of the nut 106c, allows the four nuts 106c to be gradually fitted onto the corresponding outer wall of the screw 306. This eliminates the need to repeatedly install the four nuts 106c individually, thus improving the installation efficiency of the vibrator housing 106.
