Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a vibrating screen device for feed processing. Background Technology

[0002] Vibrating screens operate by utilizing the reciprocating rotary vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. In the use of traditional vibrating screens, the screen often becomes clogged because the volume of the material is larger than the screen opening.

[0003] Existing patent CN220387105U describes an anti-clogging vibrating screen, comprising a vibrating screen body. A motor is fixedly connected to the left side of the vibrating screen body, and a threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the surface of the threaded rod, and an extension plate is fixedly connected to the right side of the threaded sleeve. An air blowing box is fixedly connected to the right side of the extension plate. A spray pipe is connected to the top of the air blowing box, and a conveying pipe is connected to the bottom of the air blowing box. A discharge inclined plate is provided at the bottom of the inner cavity of the vibrating screen body. Fixing blocks are fixedly connected to the front and rear sides of both sides of the vibrating screen body. This technical solution, through the coordinated use of the vibrating screen body, motor, threaded rod, threaded sleeve, extension plate, air blowing box, spray pipe, conveying pipe, discharge inclined plate, fixing blocks, limiting plate, insert plate, screening screen, and blower, can periodically and automatically clean the screen holes of the screening screen, avoiding screen hole clogging and improving screening efficiency. However, the fixed spray pipe gap of this device can only clean specific screen holes. Therefore, a vibrating screen that can still be cleaned after screen replacement is needed.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1-5 A vibrating screen device for feed processing includes a vibrating screen 1. Slide grooves 2 are provided on both sides of the vibrating screen 1. A slider 3 is slidably connected inside the slide grooves 2. An extension rod 4 is fixedly installed on the side of the slider 3 away from the vibrating screen 1, extending to the bottom of the vibrating screen 1. The bottom ends of the two extension rods 4 are connected by an air jet pipe 5. The surface of the air jet pipe 5 has spray holes 6 facing the vibrating screen 1, and one end of the air jet pipe 5 has an air inlet 7. Through the air jet pipe 5, which is located below the vibrating screen 1 and can slide along the vibrating screen 1, a high-speed airflow from the spray holes 6 can impact the feed blocked in the screen holes of the vibrating screen 1 from below, thus solving the problem of clogging in the vibrating screen 1 in the prior art.

[0024] A vibration source 101 is fixedly installed above the vibrating screen 1, and a support 102 is fixedly installed below the vibrating screen 1. A chute 103 is set in the middle of the support 102 below the vibrating screen 1. This arrangement enables the vibrating screen 1 to maintain vibration and achieve the screening of feed.

[0025] A pressure stabilizing pipe 501 is provided at the bottom of the jet pipe 5. The pressure stabilizing pipe 501 is connected and communicates with the jet pipe 5 through multiple connecting pipes 502. The air inlet 7 is provided on one side of the pressure stabilizing pipe 501 and is connected to the extension rod 4. By providing the pressure stabilizing pipe 501, some gas can be temporarily stored inside the pressure stabilizing pipe 501, so that the jet pipe 5 can spray more stably and evenly when it sprays.

[0026] Sliding sleeves 503 are fixedly installed at both ends of the jet pipe 5. The sliding sleeves 503 are slidably connected to the extension rod 4. The connecting pipe 502 between the jet pipe 5 and the pressure stabilizing pipe 501 is a telescopic pipe. The bottom end of the jet pipe 5 is rotatably connected to a threaded shaft 504. A threaded sleeve 505 is fixedly installed on the outer surface of the pressure stabilizing pipe 501. The threaded shaft 504 is threadedly connected to the inside of the threaded sleeve 505. With this setting, the position of the jet pipe 5 to the vibrating screen 1 can be adjusted so that the jet pipe 5 fits the bottom of the vibrating screen 1 for jetting during use.

[0027] The jet pipe 5 is shaped as a semi-circular protrusion, which covers at least two sets of horizontal screen holes of the vibrating screen 1. The spray hole 6 is located in the middle of the annular protrusion 506 and contacts the vibrating screen 1 through the semi-circular protrusion, thereby reducing the leakage of the sprayed gas and providing sufficient pressure to spray the screen material from the screen holes of the vibrating screen 1.

[0028] A power source 8 for driving the slider 3 to reciprocate is fixedly installed on one side of the vibrating screen 1. At least one end of the slide 2 extends to the part of the vibrating screen 1 without a screen. This arrangement allows the air jet pipe 5 to reciprocate along the vibrating screen 1 and hides under the vibrating screen when the air jet pipe 5 is not working.

[0029] The power source 8 includes a chain 801 set above the slide 2. Some links of the chain 801 are fixedly connected to the slider 3. A tension wheel 802 is installed at one end of the chain 801 and a drive wheel 803 is installed at the other end. With this arrangement, the drive wheel 803 can be driven to rotate and change the direction of rotation, and the chain 801 can drive the slider 3 to achieve reciprocating motion.

[0030] In use, the jet pipe 5, which is set below the vibrating screen 1 and can slide along the vibrating screen 1, can use the high-speed airflow ejected from the spray hole 6 below the vibrating screen 1 to impact the feed that is blocked in the screen hole of the vibrating screen 1, thus solving the problem of clogging of the vibrating screen 1 in the prior art.

[0031] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
