Description

Technical Field

[0001] The utility model relates to the technical field of machinery manufacturing and maintenance, and particularly relates to a mine receiving hopper. Background Art

[0002] A receiving hopper is a device widely used in industrial production and material handling. In many industries, materials need to be transported from one process to another, and the receiving hopper is usually used as a device for receiving and temporarily storing materials. For example, in mining, after the ore is transported out from the excavation face, it first enters the receiving hopper and then is transported to subsequent processing equipment by the receiving hopper. In the construction industry, materials such as cement, sand and gravel are often received and distributed through the receiving hopper.

[0003] In mining and smelting production, large receiving hoppers are generally used to obtain sufficient material reserves to meet the normal production requirements. However, under high-intensity work, problems such as wear and damage of the hopper body and material blockage of the receiving hopper inevitably occur, affecting normal production activities. Conventionally, a supporting maintenance work platform is built around the large receiving hopper to solve the above problems. This method not only increases the construction cost but also occupies a large amount of space resources. Therefore, a mine receiving hopper is needed to reduce the construction cost and the occupation of space resources. Summary of the Utility Model

[0004] To overcome the deficiencies of the above prior art, the utility model provides a mine receiving hopper, which solves the technical problems of high construction cost and large space occupation of the receiving hopper.

[0005] To achieve the above object, the utility model is realized by the following technical solutions:

[0006] A mine receiving hopper for receiving and temporarily storing materials, comprising: a hopper body, a platform, and a pair of installation and lifting seats. The hopper body is in the shape of a trapezoidal cylinder, with a discharge opening at the lower end. The platform covers the hopper body, and there is a feed inlet on the platform. There is a receiving cavity inside the hopper body, and the receiving cavity communicates the discharge opening with the feed inlet. A plurality of lining plates are arranged along the vertical direction of the receiving cavity, and the lining plates are arranged circumferentially along the inner wall of the hopper body. The upper and lower adjacent lining plates are arranged in a staggered manner, and each lining plate is installed on the corresponding inner wall of the hopper body. A pair of installation and lifting seats are respectively installed on the opposite outer sides of the hopper body. The platform is also provided with: a discharge platform, a limiting part, a monitor installation hole, an inspection hatch, and a dust removal hood opening. The discharge platform is arranged at an interval from the feed inlet in the Y direction. The limiting part is arranged between the discharge platform and the feed inlet in the Y direction. The dust removal hood opening is arranged at an interval from the feed inlet in the Y direction. The monitor installation hole is arranged between the dust removal hood opening and the monitor installation hole. The inspection hatch is arranged at an interval from the dust removal hood opening in the X direction.

[0007] Based on the above structure, the principle of the described coal mine receiving hopper is as follows: The integration design of the platform and the hopper body can not only reduce the construction cost but also reduce the occupation of space resources. When dumping materials through the discharge opening, under the action of gravity, the materials will generate friction and impact with the inner wall of the hopper body, resulting in severe wear of the inner wall of the hopper body. The lining plate is used to prevent the materials from directly impacting the inner wall of the hopper body, reducing the wear of the inner wall of the hopper body, thereby extending the service life of the hopper body. The limiting part is used to limit the rear wheels of the material transport vehicle. As the materials are continuously discharged, the center of gravity of the material transport vehicle will gradually rise, causing the material transport vehicle to move towards the direction of the nearby discharge opening. The limiting part abuts against the rear wheels of the material transport vehicle, restricting the movement of the material transport vehicle towards the direction of the nearby discharge opening and ensuring the safety of unloading of the material transport vehicle. The opening of the dust removal hood is used to install the dust removal hood to prevent dust from polluting the air. The inspection hatch is used to inspect the interior of the hopper body, and the unloading frequency is adjusted accordingly according to the state of the materials inside the hopper body. The lining plate is designed in blocks so that when a part of the lining plate is damaged, it is convenient to replace it locally, improving the economy of the receiving hopper.

[0008] Furthermore, in a coal mine receiving hopper of the present application, a reinforcing member is provided on the outer side surface of the hopper body. The reinforcing member includes: reinforcing vertical plates and a group of reinforcing horizontal plates. The group of reinforcing horizontal plates are arranged at intervals along the vertical direction on the outer side surface of the hopper body. The reinforcing horizontal plates are arranged circumferentially along the outer side surface of the hopper body. The reinforcing vertical plates are arranged between adjacent reinforcing horizontal plates. The upper and lower ends of the reinforcing vertical plates are respectively connected to the corresponding reinforcing horizontal plates. The reinforcing vertical plates are arranged circumferentially at intervals along the outer side surface of the hopper body. As a preferred solution of the present application, the reinforcing horizontal plates in a coal mine receiving hopper of the present application are arranged on the outer side surface of the hopper body to strengthen the stiffness of the side wall of the hopper body and enhance the ability of the hopper body to resist deformation.

[0009] Furthermore, in a coal mine receiving hopper of the present application, the hopper body includes: an upper hopper body and a lower hopper body. The upper hopper body is installed on the lower hopper body, and the platform is installed on the upper hopper body. A pair of installation and lifting seats are respectively installed on the opposite outer side surfaces of the lower hopper body. As a preferred solution of the present application, the hopper body in a coal mine receiving hopper of the present application is designed in a split form as an upper hopper body and a lower hopper body. Such a design is for the convenience of processing and installation of the receiving hopper.

[0010] Furthermore, in a coal mine receiving hopper of the present application, a group of threaded locking members are provided on the lining plate. The threaded locking members are used to install the lining plate on the inner side wall of the hopper body. The threaded locking members include screws. The front end of the screw is threadedly connected with a nut. The screw penetrates through the lining plate and the hopper body. The lining plate and the hopper body are arranged between the screw head and the nut of the screw. As a preferred solution of the present application, the threaded locking members in a coal mine receiving hopper of the present application axially lock the lining plate and the hopper body by using screws and nuts, and the side surface of the lining plate is attached to the inner side surface of the hopper body.

[0011] Furthermore, a mining receiving hopper in the present application also includes: an inspection port assembly, the inspection port assembly is arranged on the outer side of the upper hopper body, the inspection port assembly includes: an inspection port, an inspection door, and a rotating mechanism, the inspection port is arranged on the outer side of the upper hopper body, the inspection port is connected to the accommodating chamber, the inspection door cover is arranged on the inspection port, the rotating mechanism is installed on the outer side of the upper hopper body, the rotating mechanism and the inspection door are arranged on the same side, the inspection door is hinged to the upper hopper body through the rotating mechanism, and the rotating mechanism is used to put the inspection door in an open or closed state. As a preferred embodiment of the present application, the inspection port in a mining receiving hopper in the present application is used as an entrance and exit for inspecting the interior of the hopper body. When the operating personnel need to enter the accommodating chamber, the inspection door is opened by the rotating mechanism, and the inspection door is separated from the inspection port; when the inspection door is in a closed state, the inspection door cover is arranged on the inspection port.

[0012] Furthermore, in the present application, a mining receiving hopper, the rotating mechanism includes: a mounting tube, an L-shaped support rod, the mounting tube is spaced apart from the inspection door in the horizontal direction, the L-shaped support rod can be rotatably nested in the mounting tube, the L-shaped support rod includes: a cross bar, a vertical rod, the vertical rod can be rotatably nested in the mounting tube, the cross bar is respectively connected to the cross bar and the inspection door, the vertical rod is provided with a retractable protrusion, the mounting tube is provided with a limiting hole corresponding to the retractable protrusion, and the limiting hole is used to accommodate the retractable protrusion. As a preferred embodiment of the present application, the rotating mechanism in the mining receiving hopper of the present application is used for opening and closing the inspection door. When the inspection door needs to be opened, first, the retractable protrusion is pressed to retract radially along the vertical rod, and the retractable protrusion exits the limiting hole. Because the cross bar is respectively connected to the cross bar and the inspection door, and the vertical rod can be rotatably nested in the mounting tube, the cross bar is moved to drive the vertical rod to rotate in the mounting tube, and the inspection door moves away from the upper bucket body, completing the opening of the inspection door.

[0013] When the inspection door needs to be closed, first move the horizontal bar to drive the vertical bar to rotate in the installation cylinder, and the inspection door moves toward the upper bucket body. When the retractable protrusion extends into the limiting hole, the retractable protrusion limits the horizontal bar so that it cannot continue to move toward the upper bucket body. At this time, the inspection door cover is set on the inspection port, and then the inspection door is installed on the upper bucket body with screws to complete the closing of the inspection door.

[0014] Furthermore, the mining receiving hopper of the present application further includes an anti-skid member installed on the platform and the unloading platform, and the anti-skid member is used to prevent slipping. As a preferred embodiment of the present application, the anti-skid member in the mining receiving hopper of the present application is used to prevent workers from slipping while working on the platform, and can increase the friction with the wheels of the material transport vehicle, ensuring that the wheels of the material transport vehicle travel stably on the unloading platform without slipping.

[0015] Further, a mine receiving hopper in the present application further includes: wear-resistant blocks, which are detachably installed at the bottom of the lower hopper body and are located at the outlet of the discharge port.
