Description

Technical Field

[0001] This utility model relates to the field of belt conveyors, and in particular to a hopper for belt conveyors. Background Technology

[0002] The belt conveyor has a discharge hopper at its head. However, after a period of use, the hopper will wear out due to the impact of the material and needs to be repaired.

[0003] However, because some of the existing hoppers are subjected to the impact of falling materials for a long time, the service life of the hoppers is relatively short. In addition, some hoppers are set in high positions, making it inconvenient for workers to repair them. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a hopper for a belt conveyor that overcomes or at least partially solves the above problems. It can solve the problem that some existing hoppers are subjected to the impact of falling materials for a long time, resulting in a short service life of the hopper. It can also solve the problem that the hopper is set up at a high position, making it inconvenient for workers to repair.

[0005] Specifically, this utility model provides a hopper for a belt conveyor, comprising:

[0006] The feed inlet is used to connect to the conveying end of the belt conveyor.

[0007] A housing, which is connected to the feed inlet. A collection port is formed on the housing, extending through its front side plate from front to back.

[0008] A material collection trough is located on the front side of the housing and is detachably connected to the material collection port. The material collection trough is a trough with its opening facing the material collection port, so that it can receive materials entering from the material collection port.

[0009] Optionally, the hopper further includes a liner plate, which is detachably connected to the inner wall of the collection trough and the housing by threaded fasteners.

[0010] Optionally, the liner includes:

[0011] A first liner plate is attached to the lower sidewall of the collection trough. In the front-to-back direction, the length of the first liner plate is the same as the length of the lower sidewall of the collection trough.

[0012] A second liner is connected to the front sidewall of the trough. The length of the second liner in the vertical direction is 1 to 1.5 times the length of the first liner in the front-back direction.

[0013] The first liner is connected to the second liner.

[0014] Optionally, the first liner includes a plurality of plates arranged laterally adjacent to each other.

[0015] Optionally, the second liner includes a plurality of plates arranged laterally adjacent to each other.

[0016] Optionally, the liner includes a third liner connected to the upper edge and / or lower edge of the collection port.

[0017] Optionally, the front sidewall of the housing is provided with a plurality of first mounting holes spaced apart around the periphery of the collection port. The rear ends of the four walls of the collection trough all extend outwards with flanges, and the flanges are provided with second mounting holes corresponding to the first mounting holes. The collection trough is fixed to the housing by threaded fasteners.

[0018] Optionally, the feed inlet is located at the top of the housing.

[0019] The hopper also includes a protective cover, which is placed on top of the feed inlet and connected to the housing via a connector.

[0020] In the hopper of this invention, the lower part of the collecting trough is covered with a layer of material. When the collecting trough is covered by the material, the material will fall directly onto the material when it enters the hopper, thereby reducing the time that the material impacts the collecting trough and improving the service life of the collecting trough. This not only reduces the cost of using the hopper, but also reduces the frequency of workers replacing the collecting trough.

[0021] In addition, since the collection trough is detachably connected to the shell, when the inner wall of the collection trough is worn, it is only necessary to remove the collection trough for repair or replacement, which avoids workers staying at a high position for a long time, improves construction safety, and makes it easier for workers to repair or replace the hopper.

[0033] Figure 1 This is a schematic cross-sectional view of a hopper according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 3 This utility model embodiment provides a hopper for a belt conveyor, the hopper including a feed inlet, a shell 2 and a collection trough 3.

[0034] The feed inlet is used to connect to the end of the belt conveyor.

[0035] The housing 2 is connected to the feed inlet. A collection port is formed on the housing 2, extending through its front side plate from front to back.

[0036] The material collection trough 3 is located on the front side of the housing 2 and is detachably connected to the material collection port. The material collection trough 3 is a trough with its opening facing the material collection port so that it can receive the material entering from the material collection port.

[0037] The location of the material collection port can be set according to the throwing curve determined by parameters such as belt speed, material particle size, and conveying angle.

[0038] In this embodiment, the material is transported to the feed inlet by a belt conveyor. Due to inertia, the material is thrown from the belt conveyor through the feed inlet into the hopper, with most of the material being thrown into the collection trough 3. Since the collection trough 3 protrudes forward from the front side wall of the housing 2, its lower part can store a certain amount of material. After the lower part of the collection trough 3 is covered with a layer of material, the material will fall directly onto the trough when entering the hopper, thus reducing the time the material impacts the collection trough 3, increasing its service life, reducing the hopper's operating cost, and decreasing the frequency of replacement by workers.

[0039] The larger the volume of the collecting trough 3, the more and thicker the material that can be stored in it, making the material feeding effect more obvious. This, in turn, reduces the impact of the material on the sidewalls of the collecting trough 3, thus extending its service life. Furthermore, the structure in this application, where the collecting trough 3 is connected to the front of the housing 2, not only increases the size of the collecting trough 3 but also avoids the difficulties in manufacturing and installing the housing 2 due to its excessive size, thereby reducing material waste and lowering the cost of the hopper.

[0040] Since the material collection trough 3 is detachably connected to the housing 2, when the inner wall of the material collection trough 3 is worn, it is only necessary to remove the material collection trough 3 for repair or replacement, which avoids workers staying at a high position for a long time, improves construction safety, and makes it easier for workers to repair or replace the hopper.

[0041] In some embodiments of this utility model, when the hopper is in working condition, the top of the rear side plate of the housing 2 is located behind the conveying end of the belt conveyor to ensure that the material can enter the housing 2.

[0042] In some embodiments of this utility model, the hopper also includes a liner plate, which is detachably connected to the inner wall of the material collection trough 3 and the housing 2 by threaded fasteners.

[0043] In this embodiment, the liner is positioned between the material and the collection trough 3 or the housing 2 to reduce wear on the collection trough 3 and the housing 2, thereby improving their service life.

[0044] When the liner plate is worn and needs to be replaced, simply remove the corresponding threaded connector and replace the liner plate.

[0045] In some embodiments of this utility model, the material collection trough 3 and the liner plate are pre-drilled mounting holes and connected by countersunk bolts. That is to say, the threaded connection can be a countersunk bolt, screw, etc.

[0046] In some embodiments of this utility model, the liner includes a first liner 4 and a second liner 5.

[0047] The first liner 4 is connected to the lower side wall of the collecting trough 3. In the front-back direction, the length of the first liner 4 is the same as the length of the lower side wall of the collecting trough 3, so that the material cannot impact the lower side wall of the collecting trough 3, further improving the service life of the collecting trough 3.

[0048] The second liner 5 is connected to the front wall of the collecting trough 3. The length of the second liner 5 in the vertical direction is 1 to 1.5 times the length of the first liner 4 in the front-back direction. When material accumulates on the collecting trough 3, the accumulation height of material near the front wall of the collecting trough 3 is higher than that of material far from the front wall of the collecting trough 3, forming a triangular shape. Furthermore, to allow more material to fall into the collecting trough 3, the height of the front panel of the collecting trough 3 is 1.6 to 2 times the length of the lower wall of the collecting trough 3 in the front-back direction. To fully protect the front wall of the collecting trough 3, setting the length of the second liner 5 in the vertical direction to 1 to 1.5 times the length of the first liner 4 in the front-back direction effectively protects the front wall of the collecting trough 3. Moreover, since the material does not contact the very top of the front wall of the collecting trough 3, setting the height of the second liner 5 to be less than the height of the front wall of the collecting trough 3 has little impact on the front wall of the collecting trough 3, and also reduces the material used for the second liner 5, lowering production and operating costs.

[0049] The first liner 4 is connected to the second liner 5.

[0050] In some embodiments of this utility model, the first liner 4 comprises a plurality of plates arranged laterally adjacent to each other. And / or,

[0051] The second liner 5 includes multiple plates arranged adjacent to each other in the transverse direction.

[0052] In this embodiment, the cost of a single plate is lower than the cost of the entire first liner 4 or the second liner 5. By making the liner segmented, different plates can be replaced as needed, thereby reducing the cost of using the liner.

[0053] In some embodiments of this utility model, the liner includes a third liner 6, which is connected to the upper edge of the collection port.

[0054] Alternatively, the third liner 6 is connected to the lower edge of the collection port.

[0055] Alternatively, a third liner 6 can be connected to both the upper and lower edges of the collection port.

[0056] In this embodiment, when the material flows toward the collection trough 3, some material will fall onto the upper or lower edge of the collection port. A third liner 6 extending in the left-right direction is provided at the upper or lower edge of the collection port to further reduce the impact and wear on the shell 2, thereby protecting the shell 2.

[0057] In some embodiments of this utility model, the front sidewall of the housing 2 is provided with a plurality of first mounting holes spaced apart around the periphery of the collection port.

[0058] The rear ends of the four walls of the material collection trough 3 are all extended outward with flanges, and the flanges are provided with second mounting holes corresponding to the first mounting holes.

[0059] The material collection trough 3 is fixed to the housing 2 by threaded fasteners.

[0060] In this embodiment, since the material collection trough 3 is detachably connected to the housing 2 via a threaded connector, when wear occurs on the inner wall of the material collection trough 3, it is only necessary to remove the material collection trough 3 for repair or replacement, thus avoiding the situation where workers linger at a high position for a long time and improving construction safety.

[0061] In some embodiments of this utility model, the threaded connector can be a bolt or a screw. Bolts or screws are relatively easy to assemble and disassemble, thus simplifying the worker's work of disassembling and assembling the material collection trough 3.

[0062] In some embodiments of this utility model, the material collection trough 3 is made of steel plates welded together.

[0063] In some embodiments of this utility model, the feed inlet is located at the top of the housing 2 so that the material falls into the feed hopper in a parabolic trajectory from a height.

[0064] The hopper also includes a protective cover 1, which covers the top of the feed inlet and is connected to the housing 2 by a connector to prevent dust from being kicked up when the material falls into the hopper, thus avoiding environmental pollution.

[0065] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
