Description

Technical Field

[0001] The utility model relates to the technical field of stone crushers, in particular to a feeding hopper for a mine stone crusher. Background Art

[0002] A mine is an independent production and operation unit that mines ore within a certain mining area. A mine primarily consists of one or more mining plants and some auxiliary plants. Most mines also include a beneficiation plant, where the mined ore is crushed.

[0003] Among them, announcement number CN216173089U discloses a feed hopper for a mining stone crusher, comprising a hopper body, an air pump, and a water pump. A sound-reducing cover is welded to the outer wall of the hopper body, and an anti-wear liner is provided on the inner wall of the hopper body. An installation opening is provided on the outer wall of one side of the sound-reducing cover, a feed plate is welded to the inner wall of the installation opening, and a fixing plate is welded to one end of the outer wall of the top of the sound-reducing cover. A chute is provided on the outer wall of one side of the fixing plate, and a servo motor is installed on the inner wall of one side of the chute. The utility model can prevent the stone from directly contacting the inner wall of the hopper body and causing wear on the inner wall of the hopper body by providing an anti-wear liner, thereby extending the service life of the hopper body and reducing the cost of use. At the same time, the anti-wear liner can be fixed from the outer wall of the hopper body by bolts, avoiding the situation where the bolts are worn when fixed from the inner wall of the hopper body, which makes it inconvenient to remove the anti-wear liner. Fixing from the outer wall of the hopper body makes it convenient to replace the anti-wear liner later.

[0004] The stones in this device are fed into the interior of the hopper body through the feed plate. However, since the sizes and shapes of the mined stones are different, when the materials are piled up inside the hopper at the same time and there are larger stones inside, it is very easy for the stones to get stuck inside the hopper, requiring manual dredging, which in turn reduces the material discharge efficiency and the crushing efficiency.

[0005] Therefore, it is necessary to invent a mine stone crusher feed hopper to solve the above problems. Utility Model Content

[0017] Optionally, a support plate is fixedly connected to the lower surface of the support frame, and the right end of the support plate is fixedly connected to the surface of the lower hopper.

[0018] By adopting the above technical solution, the support plate supports the support frame, thereby improving the stability of the support frame and the material hopper.

[0019] Optionally, multiple groups of support springs are arranged between the support frame and the material hopper, and the upper and lower ends of the support springs are fixedly connected with clamping blocks, and the clamping blocks on the upper and lower sides are fixedly connected to the lower surface of the material hopper and the upper surface of the support frame respectively.

[0020] Optionally, a mounting plate is fixedly connected to the lower surface of the material leveling hopper, and the mounting plate vibration motor is fixedly mounted on the lower side of the mounting plate.
