Description

Technical Field

[0001] This utility model belongs to the technical field of testing equipment and relates to an anti-splash feed inlet for an alternating baffle jaw crusher. Background Technology

[0002] The testing center laboratory is responsible for sample preparation of materials and tailings from the nickel smelting process. It typically uses a fully automated grinding machine. However, because the equipment requires samples to have a particle size of less than 13mm, the collected samples are mostly lumpy materials, making direct fully automated sample preparation impossible. Coarse crushing is necessary to ensure the feed particle size meets the equipment requirements. Therefore, a jaw crusher is required for coarse crushing. During the crushing process, since the materials are mostly alloys with varying shapes and high hardness, the clamping force between the two jaw plates may cause material fragments to splash out of the feed inlet, potentially injuring operators. Therefore, it is necessary to design a dedicated feed inlet to prevent material splashing during crushing and avoid safety accidents. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing an alternating baffle jaw crusher with a splash-proof feed inlet. This solves the problem that the clamping force between the two jaw plates during the coarse crushing process causes some sample fragments to splash out of the feed inlet, which can easily cause injury to operators.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An alternating baffle jaw crusher anti-splash feed inlet includes a baffle assembly and a bucket assembly placed sequentially above the crusher, with a connecting plate between the crusher and the baffle assembly;

[0006] The baffle assembly includes a first baffle plate, a second baffle plate, a third baffle plate, and a fourth baffle plate that enclose and form a hollow right-angled prism. The first baffle plate, the second baffle plate, the third baffle plate, and the fourth baffle plate are all the same in shape and size. The inner wall of the baffle assembly is provided with a first inclined plate, a second inclined plate, a third inclined plate, and a fourth inclined plate from top to bottom.

[0007] The bucket assembly includes a first bucket plate, a second bucket plate, a third bucket plate, and a fourth bucket plate that are enclosed to form a hollow quadrangular truncated pyramid. The cross-section of the bucket assembly is an inverted trapezoid. A cover plate is provided on the top of the bucket assembly, and the two are rotatably connected by a cylindrical pin.

[0008] Furthermore, the positions of the first inclined plate, the second inclined plate, the third inclined plate, and the fourth inclined plate are successively lowered along the vertical direction;

[0009] The first inclined plate and the third inclined plate are disposed on the inner wall of the second baffle plate, and the two are arranged in parallel, and the angle between them and the inner wall of the second baffle plate is 120 degrees in the clockwise direction;

[0010] The second and fourth inclined plates are disposed on the inner wall of the third baffle plate, and are arranged in parallel, forming an angle of 210 degrees with the inner wall of the third baffle plate in a clockwise direction.

[0011] Furthermore, the connecting plate is horizontally positioned.

[0012] Furthermore, a reinforcing plate is provided at the bottom of the cover plate, and the reinforcing plate is fixedly connected to the bucket assembly by a number of first screws.

[0013] Furthermore, the crusher and the connecting plate are fixedly connected by a second screw.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model achieves double-layer protection by modifying the feeding channel and adding an internal baffle, significantly reducing the risk of injury to operators caused by material splashing during the crushing process. It protects the feeding port and surrounding equipment components, prevents material splashing, reduces material loss caused by splashing in the early stage of the crushing process, makes the sample preparation site cleaner, reduces material scattering and dust, and creates a good experimental environment.

Detailed Implementation

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0020] like Figure 1 As shown, an alternating baffle jaw crusher anti-splash feed inlet includes a baffle assembly and a bucket assembly placed sequentially above the crusher 1. A connecting plate 18 is provided between the crusher 1 and the baffle assembly. The connecting plate 18 is horizontally arranged, and the crusher 1 and the connecting plate 18 are fixedly connected by a number of second screws 17.

[0021] The baffle assembly includes a first baffle plate 2, a second baffle plate 4, a third baffle plate 13, and a fourth baffle plate 15 that enclose and form a hollow right-angled prism, and the first baffle plate 2, the second baffle plate 4, the third baffle plate 13, and the fourth baffle plate 15 are all the same in shape and size; the inner wall of the baffle assembly is provided with a first inclined plate 5, a second inclined plate 14, a third inclined plate 3, and a fourth inclined plate 16 from top to bottom; the baffle assembly is welded to the lower part of the hopper body for material guidance.

[0022] The bucket assembly includes a first bucket plate 6, a second bucket plate 7, a third bucket plate 8, and a fourth bucket plate 12 that enclose and form a hollow quadrangular truncated pyramid. The cross-section of the bucket assembly is an inverted trapezoid. A cover plate 9 is provided on the top of the bucket assembly. The cover plate 9 is rotatably connected to the third bucket plate 8 by a cylindrical pin 10. A reinforcing plate is provided at the bottom of the cover plate 9. The reinforcing plate is fixedly connected to the third bucket plate 8 by a number of first screws 11. When the material enters the bucket assembly, the cover plate 9 is rotated and placed on top of the bucket assembly to establish a closed crushing channel.

[0023] like Figure 2 As shown, the first inclined plate 5, the second inclined plate 14, the third inclined plate 3, and the fourth inclined plate 16 are lowered sequentially in the vertical direction; wherein, the first inclined plate 5 and the third inclined plate 3 are set on the inner wall of the second baffle plate 4, and are arranged parallel to each other, and the angle between them and the inner wall of the second baffle plate 4 is 120 degrees in the clockwise direction; the second inclined plate 14 and the fourth inclined plate 16 are set on the inner wall of the third baffle plate 13, and are arranged parallel to each other, and the angle between them and the inner wall of the third baffle plate 13 is 210 degrees in the clockwise direction; during the crushing process of the crusher, the first inclined plate 5, the second inclined plate 14, the third inclined plate 3, and the fourth inclined plate 16 are used to prevent material from splashing at different heights.

[0024] During use, the material splashed out from the top of the crusher 1 is blocked by the first inclined plate 5, the second inclined plate 14, the third inclined plate 3 and the fourth inclined plate 16. At the same time, the cover plate 9, the bucket assembly and the baffle assembly together form a closed channel, so that the splashed fine material can bounce back into the crusher 1 through the cover plate 9 and each inclined plate for secondary crushing.
