Description

Technical Field

[0001] This utility model relates to the field of material separation technology, and in particular to an anti-clogging multi-layer screening machine. Background Technology

[0002] A screening machine is an auxiliary device used for material separation, and it is widely used in the field of material separation. The process of separating loose materials into different particle sizes by passing them through one or more screens is called screening. A screening machine is a mechanical device that uses the relative motion between the loose material and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size.

[0003] Existing screening machines have been found to have issues during the screening process, where some materials easily clog the screen holes, resulting in low material separation efficiency. Furthermore, the single feeding point and excessive material feeding at once can clog the inlet and outlet, affecting feeding efficiency and causing inconvenience. Therefore, it is essential to design a clog-resistant multi-layer screening machine with good anti-clogging performance to prevent material blockage in the screen holes and at the inlet and outlet. Utility Model Content

[0004] In order to overcome the shortcomings of existing technology, such as the easy clogging of screen holes by some materials during the screening process, resulting in low material separation efficiency, and the single feeding position of materials introduced into the machine casing through the feed inlet for screening, and the blockage at the feed inlet and outlet by too much material at one time, which affects the feeding efficiency, one of the purposes of this utility model is to provide an anti-clogging multi-layer screening machine.

[0005] One of the objectives of this utility model is achieved through the following technical solution: a clog-resistant multi-layer screening machine, comprising a support leg, an intermittent feeding mechanism, and a hammering mechanism; a housing is fixedly connected to the upper surface of the support leg, and screen plates are fixedly connected at equal intervals to the inner wall of the housing; the intermittent feeding mechanism includes a fixed sleeve, a rotating cavity is rotatably connected to the inner wall of the fixed sleeve, a drive motor is fixedly connected to one side of the fixed sleeve, and a rotating shaft is fixedly connected to the output end of the drive motor; the rotating shaft passes through the fixed sleeve and is fixedly connected to the rotating cavity; the rotating cavity... The inner wall has a first feeding channel arranged in a ring array. A feeding port is fixedly connected to the upper surface of the fixed sleeve. A second feeding channel is formed in the middle of the lower surface of the fixed sleeve, penetrating the upper surface of the casing. A pusher plate is movably connected inside the casing. A hammering mechanism is symmetrically arranged on the side wall of the casing near the pusher plate. The hammering mechanism includes a fixed rod, and rotating sleeves are equidistantly rotatably connected to the outer surface of the fixed rod. A hammering rod is fixedly connected to one side of the rotating sleeve, and a handle is fixedly connected to another side. This design facilitates intermittent and continuous feeding and hammering of the screen plate surface, thereby preventing material accumulation at the outlet of the second feeding channel and preventing material blockage of the screen plate's holes, thus effectively improving the material screening efficiency.

[0006] According to the aforementioned anti-clogging multi-layer screening machine, a support plate is fixedly connected to one upper surface of the machine casing, and the support plate is fixedly connected to the fixing sleeve. This facilitates fixing the fixing sleeve to the machine casing.

[0007] According to the aforementioned anti-clogging multi-layer screening machine, a transparent cover plate is fixedly connected to one side of the rotating chamber. This facilitates observation of the material inside the rotating chamber.

[0008] According to the aforementioned anti-clogging multi-layer screening machine, the number of screen plates is three, and the screen hole diameters of the three screen plates are all different. The dimensions of the feed inlet, the first feed channel, and the second feed channel are all the same. This facilitates the introduction of materials into the machine casing for multi-layer screening.

[0009] According to the aforementioned anti-clogging multi-layer screening machine, the front surface of the machine casing is provided with equally spaced grooves. A sliding plate is slidably connected to the inner wall of each groove. A connecting plate is fixedly connected to one side of the sliding plate. A pusher plate is fixedly connected to one side of the connecting plate and slidably connected to the surface of the screen plate. This facilitates the rapid ejection of the screened material from inside the machine casing.

[0010] According to the aforementioned anti-clogging multi-layer screening machine, the machine casing has equidistant guide ports on the side away from the pusher plate. A sealing plate is inserted into the inner wall of each guide port, penetrating the upper surface of the machine casing and interlocking with it. This facilitates the discharge of screened material into the machine casing.

[0011] According to the aforementioned anti-clogging multi-layer screening machine, a support frame is fixedly connected to the side of the support leg near the closing plate, and overlapping blocks are fixedly connected at equal intervals to one side of the support frame. A collection box is attached to the upper surface of the overlapping blocks. This facilitates the classification and collection of the screened materials.

[0012] According to the aforementioned anti-clogging multi-layer screening machine, a wear-resistant pad is fixedly connected to the lower surface of the support leg. This increases friction and improves the stability of the device.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By incorporating an intermittent feeding mechanism and a hammering mechanism, this device, compared to existing technologies, can intermittently and continuously introduce materials into the machine casing for screening. This avoids the situation where excessive material is introduced at once, causing material to accumulate and block between the upper screen plate and the second feeding channel. At the same time, the hammering mechanism can strike the surface of the screen plate, preventing some material from clogging the screen holes and affecting the screening efficiency of the screen plate. This effectively improves the screening efficiency of the material and enhances the practicality and convenience of the device.

[0015] 2. With the arrangement of the pusher plate, chute, slide plate, connecting plate, closing plate and receiving box, the screened material can be easily sorted, discharged and collected, thereby achieving rapid material collection, improving collection efficiency and effectively enhancing the practicality of the device.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The hammering mechanism 3 includes a fixed rod 31. A rotating sleeve 32 is equidistantly rotatably connected to the outer surface of the fixed rod 31. A hammering rod 33 is fixedly connected to one side of the rotating sleeve 32. A handle 34 is fixedly connected to one side of the cylinder 32. A support plate 7 is fixedly connected to the upper surface of one side of the machine housing 4. The support plate 7 is fixedly connected to the fixed sleeve 21. A transparent cover plate 8 is fixedly connected to one side of the rotating cavity 22. There are three screen plates 5, and the diameter of the screen holes of the three screen plates 5 is different. The dimensions of the feed inlet 26, feed channel one 25, and feed channel two 27 are all the same. Slide grooves 9 are equally spaced on the front surface of the machine housing 4. A sliding plate 10 is slidably connected to the inner wall of the slide groove 9. A connecting plate 11 is fixedly connected to one side of the sliding plate 10. The pusher plate 6 is fixedly connected to one side of the connecting plate 11. The pusher plate 6 is slidably connected to the surface of the screen plate 5. The machine housing 4 is provided with guide ports 12 at equal intervals on the side away from the pusher plate 6. The inner wall of the guide port 12 is inserted with a sealing plate 13. The sealing plate 13 passes through the upper surface of the machine housing 4 and is inserted into the machine housing 4. The support leg 1 is fixedly connected with a support frame 14 on the side close to the sealing plate 13. The support frame 14 is fixedly connected with a block 15 at equal intervals on one side. The upper surface of the block 15 is connected with a receiving box 16. The lower surface of the support leg 1 is fixedly connected with a wear-resistant pad 17.

[0027] The drive motor 23 is powered by an external power source. There are three screen plates 5, which divide the inside of the casing 4 into four areas, thereby achieving multi-layer screening of materials and making the screening more thorough. With the cooperation of the intermittent feeding mechanism 2 and the hammering mechanism 3, the material can be prevented from clogging the screen holes on the screen plates 5 and from accumulating at the outlet of the second feeding channel 27, thus ensuring the continuity of material feeding and the smoothness of material screening, thereby improving the efficiency of material screening. The height of the receiving box 16 is lower than the height below the guide port 12, thus ensuring the smooth collection of the screened material by the receiving box 16. At the same time, the transparent cover plate 8 is set to facilitate the observation of the material inside the rotating cavity 22, which serves as a convenient observation function.

[0028] Working principle: The material to be screened is poured into the feed inlet 26. The drive motor 23 is started, which drives the rotating chamber 22 to rotate via the rotating shaft 24. When the feed channel 25 on the outer surface of the rotating chamber 22 is aligned with the feed inlet 26, the material in the feed inlet 26 is introduced into the rotating chamber 22. When the feed channel 25 on the outer surface of the rotating chamber 22 rotates to be aligned with the feed channel 27, the material in the rotating chamber 22 is introduced into the machine casing 4 through the feed channel 27. The material is screened in multiple layers by three screen plates 5. The screen hole diameter of the upper screen plate 5 is larger than that of the middle screen plate 5, which is larger than that of the lower screen plate 5, thus screening from large to small. During the screening process, manually lifting or pressing the handle 34 upwards or downwards drives the rotating sleeve 32. Multiple hammers 33 hammer the three screen plates 5, thereby preventing material from clogging the screen holes on the surface of the screen plates 5. With the cooperation of the intermittent feeding mechanism 2 and the hammering mechanism 3, material can be prevented from clogging the area between the upper screen plate 5 and the second feeding channel 27, and material can also be prevented from clogging the inner wall of the screen holes of the screen plate 5, thus effectively improving the screening efficiency. After screening is completed, the closing plate 13 is removed from the housing 4 and the guide port 12 is closed. The connecting plate 11 is pushed to drive the four pusher plates 6 to slide on the surface of the three screen plates 5 and the bottom wall of the housing 4, thereby pushing the screened material out of the guide port 12 and into the collection box 16 for collection. This facilitates the screening and classification of materials, effectively improving the practicality and convenience of the device.
