Description

Technical Field

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

[0002] The testing laboratory is responsible for sample preparation of materials during the smelting process. While a fully automated grinding mill is typically used, the equipment requires samples to be less than 13mm in particle size. However, since the collected samples are mostly large materials, the fully automated grinding mill cannot be used for sample preparation. Therefore, the samples need to be coarsely crushed to below 13mm. Jaw crushers are used for this coarse crushing. During the crushing process, because the materials are often alloys with irregular shapes and excessive hardness, the pressure between the two jaw plates may cause material fragments to splash out of the feed inlet, potentially causing injury. Therefore, it is necessary to design a dedicated feed inlet to prevent material splashing during crushing and avoid accidents. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a tongue-shaped anti-splash feed inlet for a jaw crusher. This solves the problem that the pressure between the two jaw plates during the coarse crushing process causes some material 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] A tongue-shaped anti-splash feed inlet for a jaw crusher includes a baffle assembly disposed above the crusher, and the two are connected by a connecting plate.

[0006] The baffle assembly includes a left baffle plate and a right baffle plate arranged symmetrically, with their sides connected by a front baffle plate and a rear baffle plate respectively, and their tops connected by a curved baffle plate. The curved baffle plate has a movable baffle plate on its side, and the two are rotatably connected by a cylindrical pin. An inclined feed plate is provided above the front baffle plate.

[0007] Furthermore, the left baffle plate includes a square plate, the top of which is provided with an irregularly shaped plate. One side of the irregularly shaped plate is arc-shaped, and the other side is provided with a protrusion, the edge of which is semi-circular.

[0008] The right baffle plate and the left baffle plate are the same in shape and size.

[0009] Furthermore, the connecting plate is horizontally positioned, and screws are provided at all four corners.

[0010] Furthermore, both the front and rear baffle plates are square, and the height of the front baffle plate is lower than that of the rear baffle plate.

[0011] Furthermore, the bottom edge of the feed plate and the shaped plate protrusion are located on the same plane.

[0012] Furthermore, the curved surface of the curved baffle perfectly matches the arc-shaped edge of the irregular plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] The design of the baffle and the double-layer protection of the baffle in this utility model reduce the risk of injury to test personnel caused by material splashing, ensure the safe operation of the equipment, and extend the equipment life; it also reduces the losses caused by material splashing and improves production efficiency.

[0018] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0019] like Figure 1 As shown, a jaw crusher tongue-shaped anti-splash feed inlet includes a baffle assembly disposed above the crusher 1, and the two are connected by a connecting plate 11. The connecting plate 11 is horizontally disposed, and screws 10 are provided at its four corners. The crusher 1 and the connecting plate 11 are fixedly connected by screws 10.

[0020] The baffle assembly includes a left baffle plate 9 and a right baffle plate 4 arranged symmetrically, with their sides connected by a front baffle plate 2 and a rear baffle plate 8 respectively, and their tops connected by a curved baffle plate 6.

[0021] The curved baffle 6 has a movable baffle 5 on its side, and the two are rotatably connected by a cylindrical pin 7. The front baffle 2 has an inclined feed plate 3 above it. It should be noted that the right baffle 4 and the left baffle 9 have the same shape and size.

[0022] like Figure 2As shown, the left baffle plate 9 includes a square plate 9a, and the top of the square plate 9a is provided with an irregular plate 9b. One side of the irregular plate 9b is arc-shaped and the other side is provided with a protrusion, and the edge of the protrusion is semi-circular. The curved surface of the curved baffle plate 6 is exactly in complete contact with the arc-shaped edge of the irregular plate 9b, and the feed plate 3 and the bottom edge of the protrusion of the irregular plate 9b are located on the same plane.

[0023] Both the front baffle plate 2 and the rear baffle plate 8 are square, and the height of the front baffle plate 2 is lower than the height of the rear baffle plate 8.

[0024] During use, the splashed material is blocked by the curved baffle 6. The curved surface of the baffle 6 bounces part of the splashed material back to the crusher and changes the splashing direction of another part of the splashed material. The baffle assembly forms a receiving space to block the material. After being blocked, the material bounces back to the crusher and is crushed again.
