[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 4 The present invention will be further described below.

[0022] The easily disassembled sand screening device includes a first sliding component 1, a second sliding component 2, a support component 3, a roller component 4, and two docking components 5. The first sliding component 1 and the second sliding component 2 are slidably disposed in the support component 3, the roller component 4 is disposed in the support component 3, and the two docking components 5 are respectively disposed on the top of the first sliding component 1 and the second sliding component 2. Both docking components 5 are connected to the roller component 4.

[0023] The support assembly 3 includes an arc plate 301, and the roller assembly 4 includes a first fixing ring 404 and two mounting rings 407. The two mounting rings 407 are fixedly installed on the outer wall of the first fixing ring 404. The inner wall of the arc plate 301 has two arc grooves 302, and the two mounting rings 407 are rotatably installed in the two arc grooves 302 respectively.

[0024] In this embodiment, when the roller assembly 4 is operating normally, the two mounting rings 407 will rotate within the arc groove 302.

[0025] Specifically, the first sliding assembly 1 includes a first bracket 101 and two first sliding rods 102, both of which are fixedly installed at one end of the first bracket 101. The second sliding assembly 2 includes a second bracket 201 and two second sliding rods 202, both of which are fixedly installed at one end of the second bracket 201. The support assembly 3 also includes two fixing sleeves 303, both of which are fixedly installed on the top of the arc plate 301. The two first sliding rods 102 and the two second sliding rods 202 are slidably inserted into the two fixing sleeves 303.

[0026] Specifically, the docking assembly 5 includes a bearing housing 501, a docking shaft 502, and an external spline 503. The two bearing housings 501 are respectively fixedly installed on the top of the first bracket 101 and the second bracket 201. The docking shaft 502 is fixedly connected to the bearing inside the bearing housing 501. The external spline 503 is located at one end of the two docking shafts 502 that are close to each other.

[0027] Specifically, it also includes a chain drive assembly 6 and a motor 7. A bracket is fixedly installed on one side of the second bracket 201, and the motor 7 is fixedly installed on the top of the bracket. The two sprockets of the chain drive assembly 6 are fixedly connected to the docking shaft 502 located at the top of the second bracket 201 and the output shaft of the motor 7, respectively.

[0028] In this embodiment, starting the motor 7 drives the chain drive group 6 to rotate, which in turn drives the docking shaft 502 located at the top of the second bracket 201 to rotate, thereby driving the main shaft 401 to rotate.

[0029] Specifically, the support assembly 3 also includes two bolts 305, and the top of each of the two fixing sleeves 303 is provided with a screw hole 304. The bolts 305 are slidably inserted into the screw hole 304 by means of threads. The outer walls of the first slide rod 102 and the second slide rod 202 are provided with insertion holes 8, which are adapted to the bolts 305.

[0030] In this embodiment, in the initial state, the first slide bar 102 and the second slide bar 202 are in a mating state, and the bolt 305 is in the socket 8.

[0031] Specifically, the roller assembly 4 also includes a main shaft 401, eight connecting rods 402, four strip rods 403, and two second fixing rings 405. Both ends of the main shaft 401 are provided with internal splines 406. The main shaft 401 is sleeved between two external splines 503 through the two internal splines 406. The eight connecting rods 402 are grouped into two groups of four, and the two groups are symmetrically distributed circumferentially on the outer wall of the main shaft 401. The four strip rods 403 are respectively fixedly installed between the eight connecting rods 402. The two second fixing rings 405 are symmetrically fixedly installed between the four strip rods 403. A screen is provided between the two second fixing rings 405 and the first fixing ring 404.

[0032] Specifically, limit blocks 9 are fixedly installed on the top of the first slide bar 102 and the second slide bar 202, and two limit grooves 306 are opened on the top of the two fixed sleeves 303, and the limit blocks 9 are slidably installed in the limit grooves 306.

[0033] In this embodiment, when the first bracket 101 and the second bracket 201 are pulled to drive the first slide rod 102 and the second slide rod 202 to slide within the fixed sleeve 303, the limiting block 9 will also slide within the limiting groove 306 under the drive of the first slide rod 102 and the second slide rod 202. The limiting groove 306 and the limiting block 9 cooperate to limit the maximum distance that the first bracket 101 and the second bracket 201 can slide away from each other, preventing the first slide rod 102 and the second slide rod 202 from falling out of the fixed sleeve 303 under the drive of the first bracket 101 and the second bracket 201.

[0034] Working principle: When it is necessary to disassemble and repair the roller assembly 4, two bolts 305 can be removed to disengage them from the insertion holes 8 on the first slide rod 102 and the second slide rod 202. At this time, the first bracket 101 and the second bracket 201 will be unlocked. Then, the first bracket 101 is pulled to the left and the second bracket 201 is pulled to the right, which will cause the two bearing seats 501 to slide away from each other, thereby causing the two mating shafts 502 and the two external splines 503 to slide away from each other. As the two external splines 503 slide away from each other, they will gradually slide out of the two internal splines 406 and eventually disengage. At this time, the main shaft 401 will be unlocked, and the roller assembly 4 will stay inside the arc plate 301 through the two mounting rings 407 on the first fixing ring 404. At this time, the roller assembly 4 is in the unlocked state and can be easily removed from the arc plate 301, such as by manual handling or hoisting.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
