Description

A clog-resistant vibrating mixing device for tuff. Technical Field

[0001] This utility model relates to the field of solid screening technology, and in particular to a clogging-resistant vibrating agitator for tuff. Background Technology

[0002] Tuff is a type of volcanic clastic rock. Its main chemical composition is mainly silicon dioxide and aluminum oxide, followed by alkali metal oxides and a small amount of iron oxide. Its structure is often loose and broken, and it can contain particles of several micrometers or even smaller. In addition to the main phase of volcanic glass, it also contains a lot of clay minerals containing various bound water. It is a commonly used building material. However, before use, tuff needs to be crushed to achieve the required size. When crushing tuff, the crushed stone needs to be screened to ensure that the size of the crushed stone is appropriate.

[0003] In the prior art, regarding the screening of crushed stone, patent number 202224171207.4 discloses a bidirectional package sorting mechanism. According to the disclosed vibrating mixing pot for tuff crushed stone, it includes a frame, with several springs fixedly connected to the upper surface of the frame. A screening pot is fixedly connected to one end of the springs away from the frame, and vibrating motors are fixedly connected to both sides of the screening pot. A support is fixedly connected to one side of the upper surface of the frame, and a stirring mechanism is fixedly connected to the end of the support away from the frame. This application, by installing a stirring mechanism inside the screening pot, allows the screening pot to vibrate and screen while simultaneously agitating the crushed stone, thus accelerating the screening efficiency and preventing large pieces of crushed stone from clogging the screen holes.

[0004] In fact, crushed tuff is very prone to agglomeration due to the water absorption and bonding effect of clay minerals. Once it adheres to the screen holes, it will lead to a decrease in screening efficiency, which requires timely manual handling. Summary of the Invention

[0008] As a preferred embodiment of the above technical solution, the drive module includes a power unit, a drive turntable, an offset transmission component, and a motion conversion unit; the drive turntable is axially connected to the output end of the power unit via a key connection; the offset transmission component is eccentrically fixed on the end face of the drive turntable away from the power unit; wherein, the motion conversion unit is fixedly connected to the movable top plate, and the motion conversion unit has a guide channel that forms a crank-slider mating pair with the offset transmission component.

[0009] As a preferred embodiment of the above technical solution, the anti-clogging tuff vibrating mixing device further includes a screen plate striking assembly. The screen plate striking assembly includes a mounting base and a striking swing arm. The mounting base is fixedly disposed at the lower end of the vibrating screen plate, and the striking swing arm is pivotally connected to the mounting base via a resettable hinge joint. The outer edge of the drive turntable is circumferentially arrayed with actuating teeth. The striking swing arm includes a striking part and a follower part. The end of the striking part is hammer-shaped and abuts against the lower end face of the vibrating screen plate. The end of the follower part extends into the tooth-element accommodating area formed between two actuating teeth. When the drive turntable rotates, the striking swing arm is periodically and intermittently actuated by the actuating teeth.

[0010] As a preferred embodiment of the above technical solution, the support mechanism is composed of several elastic elements, which are mounted between the base frame and the vibrating screen plate.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] The present invention will be further explained below with reference to the embodiments:

[0029] Example:

[0030] A clog-resistant vibrating mixing device for tuff, referring to Figures 1 and 2, includes a base frame 1, a mixing and screening assembly, and an automatic unclogging mechanism disposed below the mixing and screening assembly for unclogging the assembly. The base frame 1 serves as a basic support structure for supporting other functional components. A support mechanism is provided between the mixing and screening assembly and the automatic unclogging mechanism. The mixing and screening assembly includes a pot body 21, a rotary agitator 22 partially disposed inside the pot body 21, and a vibrating screen plate 23 disposed below the rotary agitator 22. In this embodiment, the vibrating screen plate 23 has a circular cross-section and includes an outer frame ring 232 and a gridded screening section 231 disposed inside the outer frame ring 232. Multiple screening through holes are evenly distributed within the gridded screening section 231 for separating small tuff fragments. The rotary agitator 22 is positioned above the vibrating screen plate 23 via a bent support arm 14. The bent support arm 14 is part of the structure of the base frame 1 and includes a vertical section perpendicularly connected to the main body of the base frame 1 (described in detail below). The rotary agitator 22 is fixedly installed above the vibrating screen plate 23 via a cantilever section extending horizontally from the end of the vertical section towards the axis of the pot body 21. The rotary agitator 22 includes a stirring motor 221, a transmission rod 222, and a stirring part 223. The stirring motor 221 is fixedly mounted on the upper end of the bent support arm 14, while the upper end of the transmission rod 222 passes through the bent support arm 14 and is connected to the stirring motor 221. The lower end of the transmission rod 222 is fixedly connected to the stirring part 223. The lower working end face of the stirring part 223... The stirring part 223 forms a dynamic contact fit with the gridded screening section 231. The pot body 21 is cylindrical and coaxially arranged with the stirring part 223. The axial extension length of the stirring part 223 is adapted to the inner ring diameter of the pot body 21. In order to cover as much of the gridded screening section 231 as possible during the rotation of the stirring part 223, the two ends of the stirring part 223 are arc-shaped semi-circular structures. In this way, the stirring part 223 sweeps circumferentially along the radial trajectory of the inner ring of the pot body 21 during the rotation operation, thereby covering the gridded screening section 231 and effectively screening tuff. To be more specific, the automatic unblocking mechanism is set below the vibrating screen plate 23. It includes a drive module 31, a movable top plate 32, and a guide constraint assembly. The drive module 31 is fixedly set on the base frame 1. The working surface of the movable top plate 32 is vertically arranged with columnar pins 321 that are fitted into each screening through hole. The drive module 31 is connected to the movable top plate 32 to drive the movable top plate 32 to move axially.

[0031] Referring to Figure 3, the movable top plate 32 has several material discharge holes 322, which are evenly distributed on the working surface of the movable top plate 32. A continuous mesh support structure is formed between adjacent material discharge holes 322. In this embodiment, the movable top plate 32 not only supports the ejector pins 321, but also assists the ejector pins 321 in clearing blockages in the screening holes. Furthermore, it requires a channel for the stone to pass through. Therefore, in this embodiment, the movable top plate 32 is designed as a screen. This creates a support area between adjacent material discharge holes 322 to accommodate the ejector pins 321, while the material discharge holes 322 facilitate the passage of the stone.

[0032] Driven by the drive module 31, the columnar ejector pins 321 distributed in the array on the movable top plate 32 perform directional lifting motion, precisely penetrating the corresponding screening holes. This dynamic cleaning mechanism can effectively remove clay powder clumps adhering to the inner wall of the screen holes, ensuring continuous unobstructed flow of pores during screening, thereby avoiding the problem of decreased screening efficiency caused by material accumulation.

[0033] Referring again to Figure 3, the guide constraint assembly includes three guide posts 241 evenly and circumferentially fixedly distributed on the movable top plate 32, and a guide hole group 242 on the base frame 1 corresponding to the movement trajectory of the three guide posts 241. The guide posts 241 and the guide hole group 242 maintain an movable gap and form a linear sliding fit. The gap fit between the guide posts 241 and the guide hole group 242 provides a directional movement mode for the entire movable top plate 32, that is, it can only move straight up and down. The movable top plate 32 in this embodiment contains a large number of ejector pins 321. If these ejector pins 321 cannot accurately enter the corresponding screening through holes during the movement, it may cause damage to the ejector pins 321, thereby affecting subsequent use. The setting of the guide constraint assembly can avoid the above situation.

[0034] The basic frame, excluding the bent support arm 14 (i.e., the main body of the basic frame 1 mentioned above), includes a first support ring 11, a second support ring 12, and three support legs 13 arranged in a circular array. A movable top plate 32 is located inside the first support ring 11. The second support ring 12 is coaxially positioned below the first support ring 11. The support legs 13 pass through the second support ring 12 and are fixedly connected to the first support ring 11. The internal cavity of the second support ring 12 is used to place a material collection bag. Considering the weight of the crushed stone and its sharp edges, a safe and durable bag, such as a woven bag or burlap sack, is selected. The bent support arm 14 is specifically fixedly connected to the first support ring 11.

[0035] Referring to Figures 3 and 4, the actuator of the drive module 31 comprises four core units: a power unit 311, a drive turntable 312, an offset transmission component 313, and a motion conversion unit 314. The power unit 311 employs a motor structure and is positioned and installed via the assembly notch of the first support ring 11. The drive turntable 312 forms a circumferential constraint with the motor output shaft through a keyway fit. The offset transmission component 313 is fixed to the end face of the drive turntable 312 facing away from the motor by setting an eccentricity. The motion conversion unit 314 establishes a rigid transmission link with the movable top plate 32. The transverse guide channel 3141 constructed by the motion conversion unit 314 and the offset transmission component 313 form a crank-slider mechanism. This mechanism converts the rotational motion of the motor into the up-and-down linear motion of the movable top plate 32. When the motor drives the turntable 312 to rotate, the trajectory vector generated by the circular motion of the offset transmission component 313 is decomposed by the linear constraint of the guide channel 3141 and ultimately converted into the vertical reciprocating motion of the motion conversion unit 314. From the perspective of relative motion, the biasing conductor 313 exhibits periodic lateral left and right displacements within the guide channel 3141.

[0036] Referring to Figures 4 and 5, this embodiment also includes a screen plate striking assembly 4, which includes a mounting base 41 and a striking arm 42. The mounting base 41 is fixedly disposed on the lower end surface of the vibrating screen plate 23. The striking arm 42 is pivotally connected to the mounting base plate through a resettable hinge joint (the rotating joint integrates a torsion spring to achieve automatic reset). The outer edge of the drive turntable 312 is circumferentially arrayed with actuating teeth 3121, and a tooth-to-tooth receiving area is formed between two actuating teeth 3121. The striking arm 42 includes a striking part 421 and a follower part 422. The striking part 421 is normally in contact with the bottom surface of the vibrating screen plate 23, and the end of the follower part 422 extends into the tooth-to-tooth receiving area. When the turntable rotates, the circumferential tooth row alternately pushes the follower part 422, forcing the striking part 421 to perform high-frequency pulse striking on the vibrating screen plate 23. The resulting impact vibration wave effectively overcomes material clogging and improves screening efficiency.

[0037] As a further option, the aforementioned support mechanism consists of multiple elastic elements 5, specifically five compression springs in this embodiment. The support mechanism is mounted between the base frame 1 and the vibrating screen plate 23. The deformation direction of the elastic elements 5 matches the coaxial motion trajectory of the ejector pin 321 and the screening through hole. Components with elastic support capabilities can generate a certain degree of up-and-down vibration of the entire vibrating screen plate 23 when it is struck, also to facilitate material feeding. Note that in this utility model, the elastic elements 5 used for support can be compression springs, rubber pads, or gas-liquid dampers. Considering structural performance and manufacturing costs, this embodiment uses compression springs as a compromise support.

[0038] In addition, a vibration motor 6 is provided on the outer surface of the pot body 21 to assist in vibrating and discharging materials.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
