Description

Technical Field

[0002] Before mining, it is often necessary to conduct experiments on the geological conditions of the mine. Large rocks are not easy to analyze experimentally. Therefore, after obtaining large rocks, rock sampling and screening devices are often used to obtain smaller rocks as experimental samples for analysis and measurement.

[0003] During the start-up of a rock sampling and screening device, the rock vibrates, often generating a large amount of debris. This debris then disperses into the air, polluting the environment and affecting the health of the operators. Therefore, to improve the working environment, a spray device is often added during the operation of the rock sampling and screening device to prevent the dispersion of debris.

[0004] However, the above-mentioned rock sampling and screening device still has the following problems: First, due to the addition of a spraying device, a large amount of water is required, which increases the cost of use and wastes water resources; second, the debris after spraying easily adheres to the smaller rock samples screened out and is difficult to clean. If the cleaning is not thorough, it will affect the test results of the sample. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, the utility model includes a bottom box 1 for storing water. A cover plate 2 is provided on the top of the bottom box 1. There is no fixed connection between the bottom box 1 and the cover plate 2. The cover plate 2 can be lifted and closed on the top of the bottom box 1. A screening collection cylinder 3 is embedded in the top of the cover plate 2. The bottom of the screening collection cylinder 3 is connected to the top of the cover plate 2. When the cover plate 2 is opened, the screening collection cylinder 3 and the cover plate 2 move upward synchronously. A rotary screening mechanism 6 is provided in the screening collection cylinder 3. A sealing cover 4 is connected to the top of the screening collection cylinder 3 by a detachable thread. A feed pipe 5 is provided longitudinally through the middle of the top of the sealing cover 4 for feeding large rocks into the screening collection cylinder 3.

[0029] Symmetrical spray recovery mechanisms 7 are provided on the left and right sides of the screening and collecting cylinder 3. The upper end of the spray recovery mechanism 7 is connected to the top of the side of the screening and collecting cylinder 3, and the lower end of the spray recovery mechanism 7 is connected to the bottom of the side of the bottom box 1.

[0030] A connecting seat 10 is provided on the outside of the screening and collecting cylinder 3. Two lifting cylinders 9 are installed on the side of the bottom box 1 corresponding to the connecting seat 10. The output ends of the two lifting cylinders 9 are fixed to the bottom of the connecting seat 10. The cooperation between the lifting cylinders 9 and the connecting seat 10 enables the opening and closing of the cover plate 2 and the bottom box 1, reducing labor intensity and facilitating cleaning of the interior of the bottom box 1 (to remove debris from the filter mesh 706) and adding water to the bottom box 1.

[0031] A cleaning brush 705 is provided on the inner wall of the screening collection cylinder 3 . The cleaning brush 705 is in close contact with the rotating screening mechanism 6 (specifically the screening mesh cylinder 601 ) and is used to clean the rotating screening mechanism 6 (specifically the rotating screening mesh cylinder 601 ).

[0032] like Figure 2 and Figure 3As shown, the rotary screening mechanism 6 includes a screening mesh cylinder 601 located within the screening and collecting cylinder 3. A dense filter mesh 706 for filtering debris is transversely positioned within the bottom box 1. A rotating motor 604 is positioned atop the filter mesh 706, with a heat dissipation sealing frame 603 positioned outside the rotating motor 604. A collection mesh plate 602 for filtering smaller rock samples is transversely positioned atop the rotating motor 604. The collection mesh plate 602 is located at the junction of the screening and collecting cylinder 3 and the cover plate 2. The aperture of the screening mesh cylinder 601 is larger than that of the collection mesh plate 602, which in turn is larger than that of the filtering mesh 706. The screening mesh cylinder 601 is located at the top of the collecting mesh plate 602. The output end of the rotating motor 604 is provided with a rotating shaft and a bearing. The rotating shaft and the bearing pass through the collecting mesh plate 602. The other end (upper end) of the rotating shaft is provided with the screening mesh cylinder 601, so that the rotating motor 604 drives the screening mesh cylinder 601 to rotate counterclockwise in the screening collecting cylinder 3.

[0033] The spray recovery mechanism 7 includes a flexible sleeve 701, the upper end of which is connected to the top side of the screening and collecting cylinder 3, and the lower end of which is connected to the bottom side of the bottom box 1. Fixed pipes 703 are provided transversely on both sides of the top of the screening and collecting cylinder 3 for connecting with the upper end of the flexible sleeve 701; connecting pipes 8 are also provided transversely on both sides of the bottom of the bottom box 1 for connecting with the lower end of the flexible sleeve 701. A water pump 702 is provided at the upper end of the flexible sleeve 701 for pumping water in the bottom box 1 upward to the side of the screening and collecting cylinder 3 for spraying. The water pump 702 is located on the outside of the screening and collecting cylinder 3. A diversion porous plate 704 is also provided at the upper end of the flexible sleeve 701. The diversion porous plate 704 is located on the inner side of the screening and collecting cylinder 3, so that the water is diverted and sprayed after passing through the diversion porous plate 704. By providing the spray recovery mechanism 7, the recycling of spray water is achieved, the water cost is reduced, water resources are saved, and the requirements of green environmental protection and sustainable development are more met.

[0034] By setting up a rotary screening device, smaller rocks can be obtained as experimental samples in the screening and collecting cylinder 3 with the help of centrifugal rotation for analysis and measurement; by setting up a screening mesh cylinder 601 with gradually decreasing apertures, a collecting mesh plate 602 and a dense filter mesh 706, smaller rocks (for analysis and measurement experiment samples) can be obtained on the collecting mesh plate 602 in turn, and debris can be filtered from the dense filter mesh 706 (to prevent contamination of the water in the bottom box 1), thereby achieving filtration separation between the debris after spraying and the screened smaller rock samples, avoiding the debris from adhering to the surface of the rock sample, reducing the difficulty of cleaning the rock sample, and preventing the detection results of the rock sample from being affected by the adhesion of debris.

[0035] The rock sampling and screening device for mining geological experiments described in the utility model is used as follows:

[0036] Start the two lifting cylinders 9 and synchronously lift the connecting base 10 upward, which drives the screening collection cylinder 3 and the cover plate 2 upward, separating the cover plate 2 from the bottom box 1, and adding sufficient water to the bottom box 1. Start the two lifting cylinders 9 again and synchronously drive the connecting base 10 downward, which drives the screening collection cylinder 3 and the cover plate 2 downward, completing the closing of the cover plate 2 and the bottom box 1.

[0037] The large rocks are put into the screening collection cylinder 3 from the feed pipe 5, and the rotating motor 604 is started to drive the screening mesh cylinder 601 to rotate counterclockwise in the screening collection cylinder 3. The smaller rocks are thrown out of the screening mesh cylinder 601 by centrifugal force and scattered on the collection mesh plate 602 in the screening collection cylinder 3, thereby achieving the screening of rocks of different volumes; and the counterclockwise rotation causes the gas to flow downward, driving the debris splashed during the rotation to move downward for subsequent cleaning. During this process, the water pump 702 is started, and water is transported from the bottom box 1 through the flexible sleeve 701 to the top of both sides of the screening collection cylinder 3, and finally sprayed out in the form of a spray, which can not only suppress the diffusion of debris, but also drive the debris to flow downward. The debris passes through the collection mesh plate 602 and finally stays on the filter mesh 706, thereby achieving the separation between the debris and the smaller rock samples, and also preventing the debris from polluting water resources and achieving the recycling of water resources.

[0038] During the operation of the rotating motor 604, the cleaning brush 705 can continuously clean the rotating screening mesh drum 601, preventing smaller rocks and debris from adhering to the screening mesh drum 601, thereby enhancing the use effect and ensuring the sustainable progress of the screening work.

[0039] After screening is complete, the sealing cap 4 is removed from the screening collection cylinder 3, allowing smaller rocks to be collected on the collection screen 602 for use as samples for analytical testing. The water in the bottom box 1 can be drained by removing the upper end of the flexible sleeve 701 from one end of the fixed tube 703. The two lifting cylinders 9 are activated again, synchronously lifting the connecting base 10 upward. This drives the screening collection cylinder 3 and the cover plate 2 upward, separating them from the bottom box 1 and allowing the debris on top of the filter mesh 706 to be cleaned.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
