Description

Technical Field

[0001] This utility model relates to the field of anti-clogging and screen cleaning devices, and in particular to an anti-clogging and screen cleaning device for a screening machine. Background Technology

[0002] Existing screening machines (such as vibrating screens) typically only clean the top layer of the screen when performing anti-clogging cleaning, using a rotating brush. This anti-clogging cleaning device includes a base for the screening machine (the screening machine is mounted on the top of the base via a spring), an adjustable-height support rod at the top of the base, a platform at the top of the support rod, a motor mounted above the platform, and a three-headed rotating brush below the motor's drive shaft. In use, by rotating the handle at the top of the support rod, the height of the support rod is adjusted, changing the height of the three-headed rotating brush so that it contacts the top layer of the screen. The motor's drive shaft then drives the three-headed rotating brush to rotate, thus achieving anti-clogging cleaning of the screen.

[0003] During use, the cleaning of the upper screen relies solely on the mechanical friction of the three-headed rotating brush. For some sticky materials or particles embedded in the screen holes, the cleaning effect of the three-headed rotating brush is obviously poor, making it difficult to completely clean them, which leads to screen blockage and affects screening efficiency. Utility Model Content

[0004] In view of the problem that the three-headed rotating brush in the above or existing technology has poor cleaning effect and is prone to clogging, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A striking component, including a screening machine frame, with a top platform on the top of the screening machine frame, and rotating brush assemblies at both the top and bottom of the top platform.

A striking head is fixedly installed at the bottom of the sliding rod, and a round-headed block is threaded inside the sliding rod. A spring is sleeved on the outside of the sliding rod. An abutting component, including a fixing ear, is fixedly installed on the outside of the top platform. A connecting ear is provided at the bottom of the fixing ear, and a connecting rod is fixedly installed at the bottom of the connecting ear. A cam block is fixedly installed at the bottom of the connecting rod.

[0006] As a preferred embodiment of the anti-clogging and screen cleaning device for the screening machine of this utility model, the rotary brush assembly includes a motor, which is fixedly installed on the top of the top platform. A transmission rod is fixedly installed at the bottom of the transmission shaft of the motor, and a three-head brush frame is fixedly installed at the bottom of the transmission rod. Brush bristles are fixedly installed at the bottom of the three-head brush frame.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides an anti-clogging and screen cleaning device for a screening machine, which can achieve the effect of cleaning blockage by combining rotation brushing and tapping. It includes a tapping component and a screening machine frame 10. A top platform 11 is provided on the top of the screening machine frame 10. Rotary brush assemblies 12 are provided on the top and bottom of the top platform 11. An insert plate 13 is provided inside the rotary brush assembly 12. A slide rod 14 is slidably installed inside the insert plate 13. A tapping head 15 is fixedly installed at the bottom of the slide rod 14. A round head block 16 is threaded inside the slide rod 14. A spring 17 is sleeved on the outside of the slide rod 14.

[0022] Specifically, the motor 121 drives the transmission rod 122 to rotate, enabling the brush bristles 124 to perform basic cleaning on the surface of the top layer screen. At the same time, using the insert plate 13 mounted on the top of the three-head brush holder 123, a striking head 15 with a reset and rebound function can be installed inside the three-head brush holder 123 as needed. Through the contact between the cam block 23 and the round head block 16, the striking head 15 can reciprocate to strike the screen when the three-head brush holder 123 rotates, further improving the cleaning effect of the brush bristles 124 and removing sticky materials and particles embedded in the screen holes.

[0023] Furthermore, the rotary brush assembly 12 includes a motor 121, which is fixedly mounted on the top of the top platform 11. A transmission rod 122 is fixedly mounted on the bottom of the transmission shaft of the motor 121. A three-head brush holder 123 is fixedly mounted on the bottom of the transmission rod 122. Brush bristles 124 are fixedly mounted on the bottom of the three-head brush holder 123.

[0024] The motor 121 drives the three-head brush holder 123 to rotate, so that the brush bristles 124 can reciprocate and rotate to clean the surface of the screen, thus realizing the function of basic cleaning of the screen.

[0025] Furthermore, the bottom of the insert plate 13 is provided with an insert strip, the interior of the three-head brush holder 123 is provided with a slot, and the insert strip at the bottom of the insert plate 13 is slidably installed in the slot inside the three-head brush holder 123. Both the insert strip at the bottom of the insert plate 13 and the interior of the three-head brush holder 123 are provided with holes, and the insert strip at the bottom of the insert plate 13 is installed in conjunction with the three-head brush holder 123 by bolts and nuts passing through the holes. The bottom of the round head block 16 is provided with a screw, and the screw at the bottom of the round head block 16 is threadedly installed inside the slide rod 14. The spring 17 is provided on the side of the insert plate 13 opposite to the round head block 16.

[0026] By inserting the insert strip into the slot and tightening it with bolts and nuts, the insert plate 13 can be assembled as needed. At the same time, the screw at the bottom of the round head block 16 can be used to separate the round head block 16 from the slide bar 14, so that the striking head 15 can be assembled as needed, or the spring 17 that is fatigued can be replaced.

[0027] Preferably, there are three bristles 124, and all three bristles 124 are made of a mixture of nylon and steel wire.

[0028] It should be noted that the composite material bristles 124 can improve the durability of use, and at the same time, can disperse some large particles or sticky materials, thereby improving the cleaning effect.

[0029] In use, insert plate 13 is inserted into the interior of three-head brush holder 123. Then, by passing bolts through the insert plate 13 and the interior of three-head brush holder 123, and tightening with nuts, insert plate 13 can be fixed. After fixing, slide rod 14 is inserted into the interior of insert plate 13, and spring 17 is sleeved on the outside of slide rod 14 above insert plate 13. Turn the screw at the bottom of round head block 16 into the interior of slide rod 14 and tighten it. The installation of striking head 15 is then completed. Using the basic elastic force of spring 17, striking head 15 can be held above the screen. Drive motor 121, which will cause transmission rod 122 to drive three-head brush holder 123 to rotate, so that brush bristles 124 start to rotate to clean the surface of screen. At the same time, when round head block 16 contacts cam block 23, due to the effect of the arc surface, slide rod 14 will move downward, pushing striking head 15 to strike the surface of screen, causing it to vibrate. This can effectively treat sticky materials or embedded particles on the screen surface.

[0030] If a low-frequency vibration of the screen is required, a single striking head 15 can be installed. If a medium-frequency vibration is required, all the holes on a single insert plate 13 can be filled. If high-frequency vibration is required, insert plates 13 can be installed in the three slots of the three-head brush holder 123. Since the drive shaft of the motor 121 rotates at a low speed, frequent striking will not damage the screen.

[0031] Example 2, refer to Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment, based on embodiment 1, further provides the assembly of a cam block 23 for triggering vibration in the anti-clogging and screen cleaning device of the screening machine, which further increases the vibration frequency. It includes a contacting component, including a fixed ear 20. The fixed ear 20 is fixedly installed on the outside of the top platform 11. A docking ear 21 is provided at the bottom of the fixed ear 20. A connecting rod 22 is fixedly installed at the bottom of the docking ear 21. A cam block 23 is fixedly installed at the bottom of the connecting rod 22. A screw and a nut are provided at the top of the docking ear 21. The screw provided at the top of the docking ear 21 slides through the interior of the fixed ear 20. The fixed ear 20 and the docking ear 21 are installed by the screw and nut.

[0032] Specifically, by merging the fixed ear 20 with the docking ear 21, the cam block 23 can be assembled, which can further increase the vibration frequency and increase the trigger frequency of the striking head 15.

[0033] If the vibration triggering frequency of the three sets of striking heads 15 is not satisfactory during use, or if it is necessary to make the vibration triggering position uniform, a docking ear 21 can be installed at the bottom of the fixing ear 20 on the other side. Through the cooperation of the stud and nut fixedly installed on the top of the docking ear 21, the cam block 23 can be added, so that the striking head 15 can be triggered in other positions.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
