Specific Embodiments

[0030] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0031] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] Currently, during transportation, the way of transferring pellet ore between belt conveyors is through the reverse transportation by the receiving hopper. In production, problems such as wear or damage of the receiving hopper and difficulty in controlling the material flow often occur, which cannot meet the demand for stable transportation of pellet ore. There is an urgent need for a receiving hopper suitable for the on-site conditions.

[0033] Based on this, embodiments of the present disclosure provide a receiving hopper for a pellet conveyor. On the basis of the hopper body, a bottom plate is added to form a receiving platform, and at the same time, a partition plate forms a material receiving space and a discharging space. The transported pellets receive materials through the material receiving space. The materials accumulate in the material receiving space formed by the hopper body, the partition plate and the bottom plate. During the continuous feeding process, the impact force of the newly fed materials is applied to the previous materials, achieving the purpose of protecting the hopper body, and transforming the impact action on the hopper body into a frictional action on the hopper body, greatly improving the stability of material transportation.

[0034] The receiving hopper of the pellet conveyor will be described in detail through specific embodiments as follows:

[0035] Refer to Figures 1 to 4 As shown, the present disclosure provides a receiving hopper for a pellet conveyor, including a hopper body 1 having a feed inlet 11 and a discharge outlet, and the feed inlet 11 and the discharge outlet are oppositely arranged; a bottom plate 2 is arranged on one side of the discharge outlet, and the bottom plate 2 has a material guiding port 21, and the size of the material guiding port 21 is smaller than the size of the discharge outlet; a discharging part 3 has a feed inlet 31 and a discharge outlet 32, the feed inlet 31 is connected to the material guiding port 21, and the discharge outlet 32 is oppositely arranged to the feed inlet 31; a partition plate 4 is arranged in the hopper body 1 and connected to the bottom plate 2 and / or the hopper body 1, and the partition plate 4 defines the hopper body 1 into a material receiving space 13 and a discharging space 14. The material receiving space 13 and the discharging space 14 are communicated through the bottom plate 2, and the material guiding port 21 is arranged in the discharging space 14.

[0036] In this embodiment, based on the hopper body 1, the present disclosure adds a bottom plate 2 to form a receiving platform. Meanwhile, the partition plate 4 forms a material receiving space 13 and a discharging space 14. The transported pellet ore receives materials through the material receiving space 13. The materials accumulate in the material receiving space 13 formed by the hopper body 1, the partition plate 4 and the bottom plate 2. During the continuous feeding process, the impact force of the newly fed materials is applied to the previous materials, achieving the purpose of protecting the hopper body. The impact effect of the materials on the hopper body 1 is transformed into a frictional effect on the hopper body 1, greatly improving the stability of material transportation. Specifically, the hopper body 1 of the present disclosure can be made of alloy material, steel material, etc. The present disclosure specifically selects Q235 steel. The size of the feed inlet 11 of the hopper body 1 is determined according to the width of the conveyor belt, and the size of the discharge outlet is set to 600mm X 600mm. The material of the bottom plate 2 of the present disclosure is specifically selected as Q235 steel. The bottom plate 2 has a material guiding port 21 as the outlet of the materials, and the size of the material guiding port 21 is smaller than that of the discharge outlet. The specific size of the material guiding port 21 can be set to 400mm X 400mm. Then, a part of the space at the discharge outlet is set as the bottom plate 2, and this part serves as the receiving platform to relieve the impact force of the materials on the hopper body 1. It should be noted that the material guiding port 21 of the present disclosure can be formed by the bottom plate 2 itself, that is, all four sides of the material guiding port 21 are the bottom plate 2, or at least one side of the material guiding port 21 is the bottom plate 2, such as a concave plate, an L-shaped plate and a U-shaped plate. The height of the partition plate 4 of the present disclosure is determined according to the sizes of the bottom plate 2 and the hopper body 1, and the bottom length is equal to 2 / 3 of the length of the lower side of the hopper body 1.

[0037] In some embodiments, a flow guiding plate 5 is further included, which is arranged in the discharging space 14, and the flow guiding plate 5 and the partition plate 4 are respectively arranged on two adjacent sides of the material guiding port 21. The flow guiding plate 5 is used to guide the materials to flow towards the material guiding port 21.

[0038] In this embodiment, the present disclosure arranges the flow guiding plate 5 at the position of the discharging space 14. The shape of the flow guiding plate 5 can be selected as square, rectangular and other shapes adapted to the material form. The present disclosure specifically selects a rectangle. One end of the flow guiding plate 5 is connected to the inner wall of the hopper body 1, and its body part serves as a flow guiding surface in contact with the materials, guiding the materials into the material guiding port 21 to prevent the materials from piling up towards the inner wall side of the hopper body 1, resulting in material blockage.

[0039] In some embodiments, an adjusting member is further included. The adjusting member is connected to the inner wall of the bottom plate 2 and / or the hopper body 1, and the adjusting member is used to adjust the flow guiding angle of the flow guiding plate 5.

[0040] In this embodiment, the flow guiding plate 5 is connected to the hopper body 1 through an adjusting member. The adjusting member can be selected as a hinge, a bearing and other rotating members. The present disclosure specifically selects a hinge. It can be understood that in order to fix the angle of the flow guiding plate 5, when the flow guiding plate 5 is adjusted to the required angle, the angle of the adjusting member can be locked, such as being fixed by a bolt or a clamping member.

[0041] In some embodiments, the bottom plate 2 is arranged in an "L" shape, and the edge of the bottom plate 2 overlaps with the edge of the discharge port. In this embodiment, the bottom plate 2 serves as the bottom plate of the hopper body 1 for setting the discharge port. Based on the discharge port, a material guiding port 21 is formed by the L-shaped bottom plate 2. The partition plate 4, the bottom plate 2 and the inner wall of the hopper body 1 form a material accommodating space 13. This setting method can better accommodate the material and enable the material to be better guided. Further, the bottom plate 2 is arranged as a flat plate to facilitate the accommodation of the material.

[0042] In some embodiments, the hopper body 1 is arranged in a horn shape, and the wide mouth of the hopper body 1 is set as the feed inlet 11, and the material enters the hopper body 1 through the feed inlet 11 of the material accommodating space 13.

[0043] In this embodiment, the material enters the hopper body 1 through the feed inlet 11 of the material accommodating space 13, and the material directly contacts the bottom plate 2 in the material accommodating space 13 to prevent the hopper body 1 from being damaged due to the impact of the material. Further, the cross-section of the hopper body 1 of the present disclosure is a right trapezoid.

[0044] In some embodiments, an anti-overflow plate is arranged at the feed inlet 11, and the anti-overflow plate is used to prevent the material from overflowing from the material accommodating space 13. In this embodiment, the anti-overflow plate can be connected to the inner wall of the hopper body 1, and the anti-overflow plate extends obliquely in the direction opposite to the inside of the hopper body 1 to avoid affecting the material from entering the material accommodating space 13.

[0045] In some embodiments, the surface of the bottom plate 2 arranged inside the hopper body 1 is arranged as a wavy surface. In this embodiment, the surface of the present disclosure in contact with the bottom plate 2 is arranged as a wavy shape, which can slow down the impact force of the material on the bottom plate 2 and further improve the service life of the present disclosure.

[0046] In some embodiments, a protective plate is arranged on one surface of the inner wall of the hopper body 1 and the bottom plate 2 in the hopper body 1, and the protective plate is detachably connected to the hopper body 1 and the bottom plate 2. In this embodiment, the protective plate is a structure in contact with the material. When the protective plate is damaged, it can be replaced and maintained, which can improve the use efficiency of the present disclosure and avoid long-term shutdown maintenance caused by the damage of the bottom plate 2.
