Description

Technical Field

[0001] This application relates to the field of vibrating screen bucket technology, and in particular to a vibrating screen bucket that prevents material jamming. Background Technology

[0002] The vibrating screen bucket generates high-frequency vibration through a motor or vibrator, causing the screen surface to form a three-dimensional vibration trajectory (such as a circle, a straight line, or an ellipse). The material generates a jumping motion on the screen surface. Fine particles pass through the screen holes and are completely screened, while larger particles, due to insufficient kinetic energy, remain at the top layer and are eventually discharged from the discharge port.

[0003] During the screening process, agglomerated particles can cause the volume of the particles to be larger than the mesh size of the screen, which can easily lead to material blockage during the vibration of the vibrating screen.

[0004] Therefore, in response to the above problems, the applicant provides a vibrating screening hopper that prevents material jamming. Utility Model Content

[0014] In summary, this application includes the following beneficial technical effects: In this invention, when the motor is turned on, the active bevel gear rotates, and the active bevel gear meshes with the driven bevel gear 1 and the driven bevel gear 2. The rotation of the driven bevel gear 1 drives the stirring rod 1 to rotate forward, and the rotation of the driven bevel gear 2 drives the stirring rod 2 to rotate in reverse.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses a vibrating screen bucket for preventing material jamming.

[0020] like Figure 1-5 As shown, a vibrating screen hopper for preventing material jamming includes a hopper 30. The hopper 30 is equipped with an anti-jamming mechanism for impacting materials. The anti-jamming mechanism includes a motor 20. The rotating end of the motor 20 is fixedly connected to a driving bevel gear 21.

A drive plate 43 for gathering materials is provided on the turntable 42.

[0022] Please see Figures 1 to 3 The motor 20 is fixedly connected to the motor support base 104, and the motor support base 104 is vertically fixedly connected to the bracket 103. The motor 20 is connected to an external power source.

[0023] Please see Figures 1 to 3The inner ring of the driven bevel gear 22 is fixedly connected to a connecting rod 23, and the connecting rod 23 is fixedly connected to a stirring rod 24. The inner ring of the driven bevel gear 25 is fixedly connected to a sleeve 26, and the sleeve 26 is fixedly connected to a stirring rod 27. The connecting rod 23 passes through the sleeve 26. The stirring rod 24 is located below the stirring rod 27. The stirring rods 24 and 27 are located above the dividing hopper 30. The motor 20 is turned on, driving the driving bevel gear 21 to rotate. The driven bevel gear 22 rotates forward while the driven bevel gear 25 rotates in reverse. The rotation of the driven bevel gear 22 drives the connecting rod 23 and the stirring rod 24 to rotate forward, while the rotation of the driven bevel gear 25 drives the sleeve 26 and the stirring rod 27 to rotate in reverse. The rotating stirring rods 24 and 27 force the screened material in the hopper 30 to tumble, causing the material to collide with the stirring rods 24 and 27, thereby breaking up agglomerates and removing residues from the particles, thus preventing the agglomerated particles from clogging the mesh of the hopper 30.

[0024] Please see Figure 1 and Figure 3 The connecting rod 23 is rotatably connected to the limiting rod 101, and the sleeve 26 is rotatably connected to the limiting rod 102. The limiting rod 101 and the limiting rod 102 are both fixedly connected to the bracket 100. The motor 20, the driving bevel gear 21, the driven bevel gear 22, the connecting rod 23, the stirring rod 24, the driven bevel gear 25, and the sleeve 26 are combined to form a forward and reverse rotation assembly 2. The limiting rod 101 and the limiting rod 102 are used to limit the connecting rod 23 and the sleeve 26.

[0025] Please see Figure 5 The discharge bin 31 is fixedly connected to the edge of the hopper 30. The top surface of the discharge bin 31 is fixedly connected to the motor 6. The motor 6 is connected to an external power supply. The hopper 30 acts on the vibrating screen, which is not shown in the drawing.

[0026] Please see Figure 5 The top surface of the hopper 30 is fixedly connected to a recessed disc 40, and a turntable 42 is rotatably connected to the outer circumference of the recessed disc 40. Multiple fixed shafts 41 are fixedly connected in a ring array on the recessed disc 40, and the multiple fixed shafts 41 are respectively connected through guide holes 420.

[0027] Please see Figure 5The guide holes 420 are arranged in a ring array and pass through the turntable 42. Multiple drive plates 43 are rotatably connected to multiple fixed shafts 41. The bottom of the multiple drive plates 43 is provided with a sliding block and slides in the limiting groove opened in the concave disc 40. The distance between the drive plate 43 and the mesh surface is between 1cm and 1.5cm. The concave disc 40, fixed shafts 41, turntable 42 and drive plates 43 are combined to form a petal opening and closing assembly 4.

[0028] The implementation principle of the anti-jamming vibrating screen bucket in this application embodiment is as follows: When motor 20 is turned on, it drives the active bevel gear 21 to rotate. The active bevel gear 21 meshes with the driven bevel gear 22, causing it to rotate forward while simultaneously causing the driven bevel gear 25 to rotate in reverse. The rotation of the driven bevel gear 22 drives the connecting rod 23 and the stirring rod 24 to rotate forward, while the rotation of the driven bevel gear 25 drives the sleeve 26 and the stirring rod 27 to rotate in reverse. The rotating stirring rods 24 and 27 forcefully agitate the screened material in the hopper 30, causing the material to collide with the stirring rods 24 and 27, thereby breaking up agglomerates and removing residues from the particles, thus preventing the agglomerated particles from clogging the mesh of the hopper 30.

[0029] When a large amount of particles accumulate at the edge of the hopper 30, the second motor 6 is turned on. The second motor 6 drives the bevel gear 7 to rotate, the bevel gear 7 drives the conical rack 5 to rotate, the conical rack 5 pulls the turntable 42 to rotate, the turntable 42 drives the guide hole 420 to rotate, the guide hole 420 limits the fixed shaft 41 and guides the drive plate 43 to gather, so that the material gathers from the edge to the middle of the hopper 30.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
