Description

Technical Field

[0001] The utility model relates to the technical field of mining gravel cleaning and screening devices, and specifically to a mining gravel cleaning and screening device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. They can be divided into two categories: metallic minerals and non-metallic minerals. Ores have a wide range of uses. After being processed step by step such as crushing and grinding, they can be applied in multiple engineering fields. After the ore is mined, it needs to be screened to remove the mixed gravel.

[0003] In the prior art, most of the ore is screened by a drum or vibrating screening structure. During the ore screening process, crushed stones are discharged through the holes of the screening structure, while larger ores are gradually discharged through the end of the screening structure and collected. Although this method can effectively screen the ore, when it is used, due to its own viscosity or humidity and other factors, the ore is easy to stick to each other during the screening process to form larger clumps, thereby affecting the screening work. In addition, since the position of the discharge plate is fixed, long-term use will cause the discharged crushed stones to pile up together, forming a protrusion in the middle. Utility Model Content

[0004] The purpose of the utility model is to provide a mining gravel cleaning and screening device to solve the problem that due to factors such as the viscosity or humidity of the ore itself, the ore is easily adhered to each other during the screening process to form larger clumps, thereby affecting the screening work; and because the position of the discharge plate is fixed, long-term use will cause the discharged gravel to pile up together, forming a protrusion in the middle.

[0005] The utility model provides the following technical solutions: a mining gravel cleaning and screening device, comprising a screening box body, the upper top of the screening box body is fixedly connected with a feed port, the outer side wall of the screening box body is fixedly connected with a first connecting plate and a second connecting plate, the outer side wall of the screening box body is fixedly connected with a water outlet pipe, a screening assembly for screening ore is arranged inside the screening box body, spray assemblies for reducing ore mud and sand are arranged on both sides of the screening assembly inside the screening box body, and an adjusting assembly for adjusting the falling position of gravel is arranged inside the screening box body.

[0010] By adopting the above scheme, after the servo motor starts working, it can drive the driving rod and the first synchronous wheel to work, thereby driving the synchronous belt and the second synchronous wheel to rotate. At this time, the second synchronous wheel can drive the screening frame to reciprocate through the fixed rod and the traction rod, and the ore that does not meet the requirements can be screened out, and the ore that meets the requirements can be directly discharged under the drive of the screening frame.

[0011] As a preferred embodiment of the above technical solution, the liquid spray assembly includes a high-pressure water pump fixedly connected to the outer wall of the screening box body, the output end of the high-pressure water pump is fixedly connected to a three-way pipe, the other two ends of the three-way pipe are fixedly connected to a hydraulic pressure device, the outer wall of the hydraulic pressure device is fixedly connected to a plurality of liquid nozzles, and the upper top of the hydraulic pressure device is fixedly connected to the inner top of the screening box body.

[0012] By adopting the above scheme, when the high-pressure water pump is working, the input end is connected to the external water source. Through the high-pressure water flow provided by the high-pressure water pump, the spray component can effectively clean the mud and impurities on the ore during the screening process.

[0014] By adopting the above scheme, the angle and position of the lower slide frame can be flexibly adjusted through the telescopic movement of the electric push rod, so that the falling position of the crushed stone in the screening box body can be accurately adjusted according to actual needs to adapt to the screening requirements of different ores. By adjusting the position of the lower slide frame, the flow path of the crushed stone in the screening box body can be controlled, thereby improving the screening effect.

[0015] As a preferred embodiment of the above technical solution, a plurality of filter holes are opened at the inner bottom end of the lower slide frame, and a filter cloth for liquid to pass through is laid at the inner bottom end of the lower slide frame.

[0016] According to the above scheme, liquid is sprayed out through the liquid spraying assembly during use, and a filter cloth is arranged inside the lower slide frame to filter the liquid during use, so that the liquid can enter the interior of the screening box body without affecting the sliding of the gravel.

[0017] As a preferred embodiment of the above technical solution, a second slide rail is symmetrically fixedly connected to the inner bottom end of the screening box body, and a collection box for collecting gravel is slidably connected to the inner bottom end of the second slide rail.

[0018] By adopting the above solution, the collecting box can be conveniently moved out from the interior of the screening box body during use.

The screening component is subjected to continuous reciprocating motion, and smaller crushed stones in the ore will fall into the interior of the lower frame through the screening frame, and enter the collection box through the inclined end of the lower frame. In this process, the liquid spraying component can spray out a pressurized water column and flush the ore to reduce the mud and sand on the surface, thereby reducing the connectivity between the ores. Since a filter cloth is provided at the inner bottom end of the lower frame, the liquid can penetrate the lower frame and enter the inner bottom end of the screening box body. At the same time, the angle of the lower frame can be adjusted by the adjusting component to avoid the protrusion of the middle part of the falling material during use.
