TECHNICAL FIELD
[0001] The utility model relates to the technical field of hopper, specifically, relates to an octagonal sieve sinking hopper. BACKGROUND
[0002] The sieve sinking hopper is also called vibrating hopper, which generally activates the material by vibrating in the working process, so as to eliminate the arching, blocking and sticking of the material, and realize the continuous and uniform discharge of the material.
[0003] However, in the actual process of screening dolomite and limestone through the sieve sinking hopper, especially limestone, due to the mineral composition and particle structure, it has strong brittleness. When these minerals are frequently vibrated in the vibrating hopper, the particles with high hardness are easily broken into smaller particles, forming dust, and flying to the air and the surrounding ground during the material (discharge) process of the sieve sinking hopper, resulting in dust flying in the working environment, which not only affects the hygiene of the working environment, but also easily damages the respiratory system of the workers, and even causes occupational diseases.

[0014] 1. The utility model mainly comprises a bucket body and a vibrating device for vibrating the materials in the bucket body, wherein the bucket body comprises a feeding port and a discharge pipe, that is, the materials entering the bucket body from the feeding port are uniformly discharged from the discharge pipe through the vibrating work of the vibrating device.
[0015] The discharge pipe is provided with a first outlet, a second outlet and a dust screening plate, the dust screening plate is obliquely arranged on the discharge pipe and located between the first outlet and the second outlet, so that the dust screening plate can guide the granular materials that cannot pass through the dust screening plate to the first outlet, and the powdery materials that can pass through the dust screening plate can directly pass through the dust screening plate and enter the second outlet, thereby realizing material diversion.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0025] As shown in Figure 1 , the present embodiment proposes an octagonal sieve material sink, which comprises a hopper body 1 and a vibrating device 2 for vibrating the material inside the hopper body 1. The hopper body 1 has an inlet 11 and a discharge pipe 12. That is, through the vibrating action of the vibrating device 2, the material entering the hopper body 1 from the inlet 11 is uniformly discharged from the discharge pipe 12.
[0026] The discharge pipe 12 is provided with a first outlet 121, a second outlet 122, and a dust screen plate 3. The dust screen plate 3 is obliquely arranged on the discharge pipe 12 and is located between the first outlet 121 and the second outlet 122. That is, the dust screen plate 3 plays a guiding role and can guide the material to the first outlet 121, realizing split-flow conveying.
[0027] Specifically, as shown in Figures 3-4 , the dust screen plate 3 in the present embodiment comprises a plurality of first dust screen holes 31 and a plurality of second dust screen holes 32. That is, the dust screen plate 3 is provided with a plurality of different types of dust screen holes to screen the material. The material passing through the dust screen holes is the dust type material, which still maintains the falling form to perform the discharging work. The material not passing through the dust screen holes is the particle type material, which is affected by the obliquely arranged dust screen plate 3 and performs the discharging work in the form of sliding or rolling along the surface of the dust screen plate 3.
[0028] The first dust screening holes 31 and the second dust screening holes 32 differ in that the central axes of each first dust screening hole 31 are parallel to the central axis of the discharge pipe 12, while the central axes of each second dust screening hole 32 are perpendicular to the end face of the dust screening plate 3. In other words, in addition to the normally structured first dust screening holes 31, there are also a plurality of second dust screening holes 32 with different angles (compared with the discharge pipe 12) on the dust screening plate 3. The second dust screening holes 32 arranged at different angles can change the flow trajectory of the particles, reduce the contact area between the particle-type material and the second dust screening holes 32 when they come into contact, thereby reducing the friction between them, avoiding the particle-type material from being stuck in the second dust screening holes 32, and ensuring that there is always a passage on the dust screening plate 3 for the dust-type material to pass through.
[0029] In addition, the first dust screening holes 31 and the second dust screening holes 32 are arranged alternately on the dust screening plate 3. The alternately arranged first dust screening holes 31 and second dust screening holes 32 can effectively enhance the flowability of the material when it passes through the screen plate. The combined use of the first dust screening holes 31 and the second dust screening holes 32 can avoid a single flow direction of the material on the screen plate, reduce the retention and aggregation of particles. When the material passes through the screen holes with different angles, it is helpful to cause more frequent disturbance during the screening process, so that the dust-type material can pass through the dust screening plate 3 more uniformly, thereby improving the overall screening efficiency.
[0030] In summary, since the dust screening plate 3 interrupts the falling path of the material, and under the action of the dust screening plate 3, the material entering the embodiment is classified into dust-type material and particle-type material in the discharge pipe 12. Regarding the discharge modes of these two materials: first, the dust-type material continues to fall from the second outlet 122 by passing through the dust screening plate 3. Since the dust-type material is affected by the dust screening plate 3 in the middle, the falling distance of the dust-type material is cut into two sections, thereby shortening the final discharge falling height of the dust-type material, and further avoiding the possibility of the powder-type material being in contact with air for too long during the subsequent continuous falling process until it is discharged through the second outlet to the collection box or other components, thereby reducing the possibility of air flow or air flow disturbance caused thereby, and avoiding the falling dust from being affected by air flow or air flow disturbance to appear scattered;
[0031] Second, although the particle-type material will still contact the dust screening plate 3 in a falling manner, the contact site is inside the discharge pipe 12. Therefore, it is difficult for the dust produced by the falling of the particle-type material to drift out of the discharge pipe 12, affecting the working environment around the embodiment. In the subsequent discharge process, the material moves to the conveying device or the collection box in a sliding or rolling manner along the dust screening plate 3. Compared with the falling discharge mode, the material contacts a relatively flat surface during the contact process, and there is not so much impact force or dramatic change, thereby reducing the opportunity of dust production, and further avoiding the situation of dust flying.
[0032] At the same time, asFigures 1-2 As shown, the dust screen plate 3 should be rotationally connected with the discharge pipe 12, in detail, the dust screen plate 3 is reversely arranged on the discharge pipe 12, so as to adjust the inclination angle of the dust screen plate 3 by the staff. The preferred inclination angle of the dust screen plate 3 should be that it keeps in abutment with the first outlet 121, so that it can transmit the force caused by the falling impact of the material to the discharge pipe 12 through the abutment, thereby improving the load-bearing performance of the dust screen plate 3.
[0033] The length of the dust screen plate 3 is greater than the length of the pipe opening of the discharge pipe 12, that is, a part of the dust screen plate 3 is located outside the discharge pipe 12, which not only facilitates the discharge of the granular material to the designated position, but also facilitates the staff to adjust the angle of the dust screen plate 3. At the same time, the drive structure 4 for driving the dust screen plate 3 to swing up and down is arranged outside the discharge pipe 12, which further improves the convenience of adjusting the angle of the dust screen plate 3 in the embodiment.
[0034] If necessary, baffles can be arranged on both sides of the dust screen plate 3, the baffles are fixedly connected with the discharge pipe 12, and the dust screen plate 3 is slidably connected with the baffles, so as to avoid the influence of the baffles on the up-and-down swinging work of the dust screen plate 3, and to ensure that the baffles can prevent the material sliding or rolling along the dust screen plate 3 from separating from the dust screen plate 3, thereby ensuring the stability of the material conveying in the embodiment.
[0035] Specifically, the drive structure 4 in the embodiment includes an eccentric drive shaft 41 and a drive motor 42, and the discharge pipe 12 is externally provided with a mounting bracket for mounting the eccentric drive shaft 41, the eccentric drive shaft 41 is rotationally connected with the mounting bracket, and the eccentric drive shaft 41 is located on the side of the dust screen plate 3 close to the second outlet 122 and is linked with the output shaft of the drive motor 42, that is, the drive structure 4 in the embodiment is driven by taking the drive motor 42 as the driving source, the drive motor 42 is fixedly connected with the mounting bracket, which ensures that it can stably provide driving force, and the dust screen plate 3 is in abutment with the circumferential surface of the eccentric drive shaft 41. In summary, the eccentric wheel transmission structure is adopted in the embodiment to control the change of the angle of the dust screen plate 3, compared with the structure driven by the hydraulic cylinder, the drive structure in the embodiment does not need to consider the force in the opposite direction, but only needs to continuously provide output force in one direction, which helps to prolong the service life of the driving source; and the eccentric shaft is used as the driving part, which can provide a larger contact area compared with the traditional driving wheel, which facilitates the driving force to act on the dust screen plate 3, thereby ensuring the stability of force transmission.
[0036] And with the continuous output of the drive motor 42, the angle of the dust screen plate 3 can be changed continuously, so as to exert a certain vibration force on the material located on the dust screen plate 3, effectively avoiding the blocking phenomenon at the first outlet 121 and on the dust screen plate 3, and effectively ensuring the stability of the discharging work in the embodiment.
[0037] In order to improve the service life of the dust screen plate 3, a buffer pad 6 is arranged between the dust screen plate 3 and the first outlet 121, the buffer pad 6 is fixedly connected with the discharge pipe 12, the buffer pad 6 is preferably made of elastic material such as rubber, so that when the eccentric driving shaft 41 rotates to the low point (the dust screen plate 3 no longer abuts against the eccentric driving shaft 41), the dust screen plate 3 is prevented from falling by gravity and impacting the bottom wall (the discharge pipe 12) of the first outlet 121, thereby affecting and damaging the structure; at the same time, the buffer pad 6 can also help the dust screen plate 3 to buffer the impact force from the falling material, thereby improving the service life of the dust screen plate 3.
[0038] In order to prevent the dust generated when the material falls on the dust screen plate 3 from flowing out along the first outlet 121, the first outlet 121 is provided with a dust curtain 5, one end of the dust curtain 5 away from the dust screen plate 3 is fixedly connected with the first outlet 121, and the other end of the dust curtain 5 close to the dust screen plate 3 abuts against the dust screen plate 3, so that when the material slides or rolls along the dust screen plate 3 to the dust screen plate 3 or a sufficient amount of material is accumulated at the first outlet 121, the dust curtain 5 will be opened outwardly due to the force, thereby effectively avoiding that the existence of the dust curtain 5 affects the normal conveying work of the material; and with the change of the angle of the dust screen plate 3, the dust curtain 5 will also be bent (moved) due to the abutting relationship with the dust screen plate 3, so that the dust curtain 5 still plays a dustproof role.
[0039] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
