Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mineral processing equipment, and particularly relates to a raw ore discharging hopper. BACKGROUND

[0002] The raw ore discharging hopper is commonly used in the ore supply process of mineral processing, and is mainly used for accurately and uniformly discharging the mineral powder crushed by a crusher to a belt after the mineral powder is collected and gathered, so as to effectively reduce problems such as powder ore spilling and belt deviation. However, the traditional raw ore discharging hopper usually adopts a fixed lining steel plate. Since the humidity of the raw ore is relatively high, the mineral powder is easily attached to the inner wall of the hopper. With the passage of time, the accumulation of the mineral powder becomes thicker and thicker, which causes the discharging hopper to be frequently blocked, and manual cleaning is required every one or two hours, thereby reducing the ore supply efficiency. In addition, uneven ore supply can also cause uneven stress on the belt, thereby causing problems such as belt deviation, scratching, wear and tear, and even tearing.

[0003] The traditional discharging hopper is a common steel hopper with a fixed lining plate. The humid mineral powder is easily accumulated on the inner wall of the hopper, and finally blocks the lower opening of the hopper. Therefore, how to effectively solve the blocking problem of the discharging hopper has become one of the technical problems that need to be solved at present. SUMMARY

[0004] The utility model aims to provide a raw ore discharging hopper, which solves the blocking problem of the traditional discharging hopper caused by the attachment of the mineral powder to the inner wall by improving the structure of the hopper, improves the ore supply efficiency, reduces the downtime of the equipment, and improves the safety of the operation.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the overall concept of the utility model, the following will be described in detail with reference to the accompanying drawings.

[0021] In the description of the utility model, it is understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a kind of raw ore blanking funnel, including fixed saddle 1 and inner lining stick 2, fixed saddle 1 diameter is 1.2m steel ring, and multiple pin hole seats 11 are uniformly arranged on upper surface, and the top end of pin hole seat 11 is U-shaped socket with hole on both sides, the number of inner lining stick 2 corresponds to pin hole seat 11, and a pin hole plate 21 is fixed to the upper end of each inner lining stick 2, the U-shaped socket of pin hole plate 21 is inserted into pin hole seat 11, and the pin holes of the two are communicated after docking, by inserting pin hole with quick connector 5, pin hole plate 21 and pin hole seat 11 can be hinged, and quick connector 5 can be pin bolt or pin shaft with pin hole and other commonly used connecting pieces.

[0023] Further as Figure 2 As shown, inner lining stick 2 is carbon steel material, stick body 22 is inclined quadrangular prism, and is thick at upper end and thin at lower end, multiple inner lining sticks 2 and pin hole seats 11 of fixed saddle 1 are assembled one by one to form funnel shape, and a vertical lifting plate 23 is fixed to the bottom of each inner lining stick 2 and inserted into a rotary saddle 3.

[0024] Further as Figure 3As shown, the rotating saddle 3 is a steel ring with a diameter of 0.5m, and a plurality of cams 31 are uniformly fixed on the inner ring, and in this embodiment, there are 6-8 triangular cams 31. The outer ring of the rotating saddle 3 is uniformly provided with driven teeth 32, and the driven teeth 32 are in tooth connection with a driving gear 4. The driving gear 4 is connected with an external driving mechanism (not shown in the figure), and the driving mechanism drives the driving gear 4 to rotate, and in turn drives the rotating saddle 3 to rotate. The driving mechanism can be a worm gear type rotary driving device, or a stepping motor or a servo motor and other commonly used mechanical driving devices.

[0025] The scheme has the following working process: when the hopper needs to be cleaned, the driving device is started to drive the rotating saddle 3 to rotate. When the rotating saddle 3 rotates, the cam 31 will contact the lifting plate 23 at the bottom of the inner lining rod 2, and the inner lining rod 2 at the corresponding position will be lifted, so that the inner lining rod 2 is lifted around the pin hole seat 11. When the rotating saddle 3 rotates quickly, the inner lining rod 2 will be hit with the cam 31 in turn, so that the ore attached to the inner wall of the hopper can be removed.

[0026] Further as shown in Figure 2 , 4 To ensure that the inner lining rod 2 does not fall off the fixed saddle 1 during work, the quick connector 5 of the embodiment is designed as two oppositely arranged inserts, which are respectively arranged on both sides of the pin hole seat 11 and each include a boss 51, a rear seat 52, an upper sleeve 53 and a pin 54. The protrusions 511 of the two bosses 51 are respectively inserted into the through holes after the pin hole seat 11 and the pin hole plate 21 are connected, so as to form a rotatable connection between the pin hole seat 11 and the pin hole plate 21. The bottom plate 512 of the boss 51 is connected with the rear seat 52, and the rear seat 52 is arranged outside the circumference of the fixed saddle 1 and opposite to the inner lining rod 2. An arc-shaped groove 521 is formed on the outer side of the rear seat 52, and the arc-shaped grooves 521 of the two rear seats 52 are oppositely arranged. After the arc-shaped grooves 521 are formed, the inner side of the rear seat 52 forms a lower shaft seat 522, and a lower pin hole 523 is formed. The upper sleeve 53 is a single connector with arc-shaped protrusions 531 on both sides of the lower end, and the arc-shaped protrusions 531 are respectively inserted into the arc-shaped grooves 521 of the two rear seats 52. An upper pin hole 532 is formed on the arc-shaped protrusion 531, and the pin 54 passes through the two groups of upper pin holes 532 and lower pin holes 523 to connect the upper sleeve 53 and the rear seat 52. The pin 54 can be a pin shaft bolt, a pin shaft with a pin hole or a split pin and other commonly used pin shafts.

[0027] When the funnel is worn after long time use, only the single inner lining rod 2 needs to be replaced, without replacing the whole funnel, when replacing, the pin 54 is pulled out, the upper sleeve 53 is removed, the boss 51 is loosened, and the old inner lining rod 2 can be removed. When installing the new inner lining rod 2, the pin hole plate 21 of the inner lining rod 2 is inserted into the U-shaped socket of the pin hole seat 11, then the boss 51 of the quick connector 5 is inserted into the two sides of the pin hole seat 11, the pin hole seat 11 and the pin hole plate 21 are connected, the upper sleeve 53 and the rear seat 52 are connected and fixed by the pin 54, the butt joint of the inner lining rod 2 and the fixed saddle 1 is completed. Through the setting of the quick connector 5, the dismounting and mounting of the inner lining rod 2 and the fixed saddle 1 can be quickly completed, the stability of the connection of the inner lining rod 2 and the fixed saddle 1 is ensured, and the rotating flexibility of the inner lining rod 2 is not affected.

[0028] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the protection scope of the present application.
