DETAILED DESCRIPTION

[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0035] Example 1

[0036] The preferred embodiment of the ore crushing and anti-clogging screening device provided by the utility model is as follows: Figures 1 to 4 As shown:

[0037] A screening device with anti-clogging function for ore crushing, comprising:

[0038] A mounting frame 1 is provided, with a horizontal plate 4 fixedly mounted on one side of the mounting frame 1, a bracket 5 fixedly mounted on the bottom surface of the horizontal plate 4, and a base 6 fixedly mounted on the bottom end of the bracket 5. The installed horizontal plate 4, bracket 5, and base 6 can provide a stable support for the entire device;

[0039] The feed hopper 2 is fixedly mounted on the top of the left end of the mounting frame 1, and a discharge plate 3 is provided at the discharge port on the right side of the feed hopper 2;

[0040] A crushing assembly 8 is disposed in the feed hopper 2;

[0041] The anti-blocking component 8 is arranged between the mounting frame 1 and the feed hopper 2 .

[0042] The crushing assembly 8 includes:

[0043] The motor 81 is arranged at the rear of the feed hopper 2. The output end of the motor 81 is fixedly mounted with a first shaft 82. The front end of the first shaft 82 movably passes through the back of the feed hopper 2 and extends to the inner wall of the feed hopper 2 to be rotatably connected via a bearing.

[0044] The crushing roller 84 is fixedly mounted on the outer wall of the first shaft 82;

[0045] The first gear 83 is fixedly mounted on the outer wall of the first shaft 82. The first gear 83 is meshed with the second gear 85. The inner wall of the second gear 85 is fixedly mounted with the second shaft 86. The front end of the second shaft 86 is movable through the back of the feed hopper 2 and extends to the inner wall of the feed hopper 2 and is rotatably connected to the inner wall of the feed hopper 2 through a bearing.

[0046] During the specific implementation process, the first shaft 82 is rotated by starting the motor 81, and then the first gear 83 is rotated. Under the rotation of the first gear 83, the second gear 85 is rotated, and finally the second shaft 86 is rotated, so that the two crushing rollers 84 rotate in opposite directions, which is convenient for the crushing of the ore.

[0047] In this embodiment, a motor base 10 is fixedly installed on the lower surface of the motor 81. The motor base 10 is fixedly installed on the back of the mounting frame 1. The lower surface of the motor base 10 has a hollow setting. The installed motor base 10 facilitates the stabilization of the motor 81 and enables the motor to operate normally.

[0048] Example 2

[0049] On the basis of the above embodiment, the anti-blocking component 9 includes:

[0050] The auxiliary block 91 is fixedly mounted on the outer wall of the first shaft 82. A T-shaped plate 92 is provided below the auxiliary block 91. The screen frame 11 is fixedly mounted on one end of the T-shaped plate 92.

[0051] The length of the auxiliary block 91 is greater than the distance between the lower surface of the first shaft 82 and the top surface of the T-shaped plate 92, so that the auxiliary block 91 can be smoothly squeezed onto the T-shaped plate 92 during the rotation process;

[0052] The screen frame 11 is made of rubber material. By setting the screen frame 11 of rubber material, the screen frame 11 can be easily deformed when subjected to force;

[0053] The top end of the spring 93 is fixedly mounted to the bottom surface of the mounting frame 1, and the bottom end of the spring 93 is fixedly mounted to the top surface of the screen frame 11;

[0054] An auxiliary rod 94 is fixedly mounted on the top surface of the screen frame 11, and the auxiliary rod 94 is movably sleeved with a U-shaped column 95. Both ends of the U-shaped column 95 are fixedly mounted to the bottom surface of the mounting frame 1. A large blanking plate 7 is provided below the screen frame 11. The large blanking plate 7 is fixedly mounted on the inner side of the bracket 5. The large blanking plate 7 is installed to facilitate the unloading of the ore after screening.

[0055] The auxiliary rod 94 is made of rubber material, and the auxiliary rod 94 made of rubber material can be easily deformed when the auxiliary rod 94 is subjected to force.

[0056] During the specific implementation process, the auxiliary block 91 can be rotated when the first shaft 82 rotates, and then it can be squeezed to the T-shaped plate 92. Under the setting of the spring 93, the screen frame 11 can be tilted and reciprocatingly deflected and vibrated, thereby achieving the purpose of screening and avoiding blockage of the screen frame 11.

[0057] In this embodiment, the U-shaped column 95 is fixedly sleeved with a first wedge-shaped column 96, and one side of the first wedge-shaped column 96 is in contact with a second wedge-shaped column 97 that is movably sleeved on the outer wall of the U-shaped column 95. One end of the second wedge-shaped column 97 and one side of the auxiliary rod 94, and the surfaces where the first wedge-shaped column 96 and the second wedge-shaped column 97 contact each other are both inclined surfaces.

[0058] During the specific implementation process, the auxiliary rod 94 can deflect the second wedge-shaped column 97 during the deflection process, so that it can form extrusion with the first wedge-shaped column 96. Due to the two groups of first wedge-shaped columns 96 and second wedge-shaped columns 97, the auxiliary rod 94 and the screen frame 11 will form relative extrusion and deformation, and repeat this process. This can increase the possibility of avoiding blockage of the screen frame 11 and facilitate screening work.

Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application. The various technical features described in the specification of the present invention can be selected for use alone or in combination according to actual needs. Therefore, the present invention naturally covers other combinations and specific applications related to the utility model points of this case.
