DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0034] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0035] like Figures 1 to 8 As shown in the figure, a vibration screening and cleaning device is provided in an embodiment of the present invention, comprising a sieve plate 1, a feed tray 2 located below the sieve plate 1, and a vibration mechanism for driving the sieve plate 1 to vibrate.

[0036] It also includes a flushing mechanism located above the sieve plate 1, the flushing mechanism including a main spraying assembly for flushing the material to be screened on the sieve plate 1 and a rotating spraying assembly for flushing the sieve plate 1 and the discharge plate 2;

[0037] The main spraying assembly includes a main spraying pipe 31 extending along the X-axis direction and a plurality of first spray heads 33 connected to the main spraying pipe 31 and arranged along the X-axis direction.

[0038] The rotary spraying assembly includes a rotating water pipe 41 and a rotating motor 42. The rotating water pipe 41 is arranged horizontally, one end of which is connected to the driving end of the rotating motor 42, and a second nozzle 43 is provided at the other end or near the other end. The rotating water pipe 41 rotates around the connection point with the driving end under the drive of the rotating motor 42.

[0039] With this setting, when screening materials, the main spray washing component is started. The main spray washing component can disperse the materials well and better promote the separation of the materials to be screened. The water flow will also wash away the dust adhering to the surface of the materials. No further manual cleaning is required, which improves production efficiency and reduces manual workload. After the screening is completed, the rotary spray washing component can be started to wash the screen plate and the discharge plate. At the same time, the rotary spray washing component can also cooperate with the main spray washing component when it is working to improve the material washing efficiency and coverage.

[0040] The first linear track 34 and the second linear track 35 are respectively provided on both sides of the sieve plate 1 in the X-axis direction. The first linear track 34 and the second linear track 35 are provided in parallel and extend along the Y-axis direction.

[0041] The main spray washing assembly includes a connecting transverse plate 36 extending along the X-axis direction, and the two ends of the connecting transverse plate 36 form a sliding fit with the first linear track 34 and the second linear track 35 respectively.

[0042] The main spraying pipe 31 and the connecting transverse plate 36 form a movable linkage in the X-axis direction.

[0043] Through this setting, the position of the main spray cleaning pipeline in the X-axis direction can be adjusted, which improves the flexibility of the actual application process.

[0044] The connecting horizontal plate 36 is provided with a plurality of position-limiting mounting holes 361 corresponding to the first nozzle 33 along the X-axis direction. The first nozzle 33 is position-limitingly mounted on the connecting horizontal plate 36 and its lower end passes through / penetrates the position-limiting mounting hole 361 .

[0045] Through this setting, the limiting mounting hole has a positioning effect on the main spraying pipe during the assembly process, and at the same time improves the connection stability of the main spraying pipe and the second nozzle during the application process.

[0046] A first slider 362 is fixed below one end of the connecting cross plate 36. The lower end of the first slider 362 has a slot 3621 that matches the shape of the first linear rail 34. The first slider 362 is plugged into and connected to the first linear rail 34 to form a sliding fit. A second slider 363 is fixed below the other end of the connecting cross plate 36. The center of the second slider 363 has a socket 3631 that matches the shape of the second linear rail 35. The second slider 363 is plugged into and connected to the second linear rail 35 to form a sliding fit.

[0047] Through this setting, a slot is set at the lower end of the first slider and a jack is set at the center of the second slider. The combination of the two and the linear track ensures the stability of the connection between the cross plate and the linear track and the smoothness of the sliding.

[0048] The lower end of the connecting horizontal plate 36 is connected to a waterproof cover 37 that is arranged outside the first nozzle 33.

[0049] This arrangement can prevent the water from the first nozzle from splashing, making the spraying of the first nozzle more concentrated, thereby improving the flushing effect and the cleanliness of the working environment.

[0050] Vertical plates 51 are provided on both sides of the sieve plate 1 to support both ends of the first linear track 34 and the second linear track 35. A track support plate 52 is connected to the bottom of the first linear track 34, and both ends of the track support plate 52 are fixedly connected to the vertical plates 51.

[0051] The first linear rail 34 and the second linear rail 35 are covered with a dust cover 38 .

[0052] The vibration mechanism includes a front cam group 61 and a rear cam group 62 arranged along the Y-axis direction, and at least one vibration block 63 connected to the cam, and the vibration block 63 is fixedly matched with the sieve plate 1 and / or the discharge plate 2.

[0053] The vibration mechanism also includes a second motor 64, a driving wheel 65, a driven wheel 66 and a synchronous belt 67; the second motor 64 is driven and connected to the driving wheel 65, and the driving wheel 65 is synchronously rotated and connected to the driven wheel 66 through the synchronous belt 67, and the driven wheel 66 is coaxially rotated with the front cam group 61 or the rear cam group 62.

[0054] Among them, the specific connection method between the vibration block and the sieve plate can refer to the connection form disclosed by the applicant in the utility model patent with application number 202123393652.0.

[0055] The second motor 64 is a servo motor.

[0056] Through this setting, the servo motor can rotate and transmit force at a high frequency, providing high-frequency vibration to better disperse the accumulated materials.

[0057] The sieve plate 1 and the discharge plate 2 are both tilted, and the downwardly tilted sides of the sieve plate 1 and the discharge plate 2 are respectively connected to the first drainage channel 11 and the second drainage channel 21, and the outlet ends of the first drainage channel 11 and the second drainage channel 21 are located at different positions on the horizontal plane.

[0058] This arrangement facilitates drainage of the spray cleaning structure of the device and prevents water from silting. At the same time, the staggered arrangement of the outlet ends of the first and second drainage channels facilitates the rational arrangement of the wastewater collection structure. In this embodiment, the first drainage channel has a right-angle or nearly right-angle bend.

[0059] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
