Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a sample screening device for sampling in the treatment of abandoned mines. Background Technology

[0002] Utility model patent CN219092656U discloses a mine sample screening machine with a knocking anti-clogging function, relating to the technical field of mine sample screening machines. It includes a base, a support at the lower end of the base, a shell at the upper end of the base, an anti-clogging mechanism inside the shell, a fixing frame on one side of the upper end of the base, a feed cylinder on one side of the shell, and a spiral auger feed shaft on one side of the feed cylinder. This utility model solves the problem that in existing mine sample screening machines, when screening samples of different sizes, fragmented samples clog the screen holes during the screening process, reducing the screening efficiency of the machine and preventing the machine from properly screening ore samples. This utility model, through the arrangement of an anti-clogging mechanism, a cylinder, a movable sleeve, a long column, a rubber block, a rotating column, a round shaft, and a second helical gear, achieves the effect that the reciprocating movement of the long column drives the rubber block to knock on the outside of the rotating screening cylinder, preventing the screen holes from clogging.

[0003] However, the device has certain defects in use. In the existing technology, the sample screening equipment used for sampling in the treatment of abandoned mines is prone to dust spillage during the sample screening process, which pollutes the surrounding environment. At the same time, the sample screening efficiency is not high during the screening process. Utility Model Content

[0004] The purpose of this utility model is to provide a sample screening device for sampling in the treatment of abandoned mines, which solves the problems of dust spillage and pollution of the surrounding environment during the sample screening process, as well as the low sample screening efficiency during the screening process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample screening device for sampling in the treatment of abandoned mines, comprising a shell, a protective mechanism provided on the shell, a filter cover slidably connected inside the shell, a support plate fixedly connected inside the shell, a vibration mechanism provided on the support plate, and four evenly distributed support legs fixedly connected to the lower end of the shell.

[0006] Preferably, the protective mechanism includes guide plates, with two mutually contacting guide plates hinged inside the outer shell. A support plate is fixedly connected inside the outer shell, and a square rod is slidably connected inside the support plate. A top block is fixedly connected to the upper end of the square rod, and the top block contacts the guide plates. A spring is provided on the outer side of the square rod. The spring elastically pushes the top block upward, allowing the guide plates to open and close automatically. When the sample enters the outer shell, the guide plates reset to seal the upper end of the outer shell, preventing dust spillage during the sieving process.

[0007] Preferably, a stop block is fixedly connected to the lower end of the square rod, and the stop block contacts the support plate. By setting the stop block, the square rod is limited.

[0008] Preferably, a baffle is fixedly connected inside the housing, and the baffle contacts the guide plate. The baffle seals the space between the guide plate and the housing.

[0009] Preferably, one end of the spring is fixedly connected to the top block, and the other end of the spring is fixedly connected to the support plate. By providing the spring, the top block can be easily reset.

[0010] Preferably, the vibration mechanism includes a baffle, a motor is fixedly mounted at the lower center of the support plate, the motor shaft passes through the support plate and is rotatably connected to the support plate, a slide rod is fixedly connected to the surface of the filter cover, the slide rod is slidably connected to the outer shell, and a compression spring is fixedly connected to the surface of the slide rod. The motor drives the eccentric wheel to rotate and collide with the baffle, thereby causing the baffle to move the filter cover back and forth, thus allowing the sample inside the filter cover to vibrate and be sieved, improving the sieve efficiency.

[0011] Preferably, a baffle is fixedly connected inside the housing, and an eccentric wheel is fixedly connected to the upper end of the motor shaft. The vibration of the filter cover is controlled by the cooperation of the baffle and the eccentric wheel.

[0012] Preferably, one end of the compression spring is fixedly connected to the filter cover, and the other end of the compression spring is fixedly connected to the outer shell. By providing the compression spring, the filter cover can be easily reset.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a spring to elastically push the top block upward, thereby allowing the guide plate to open and close automatically. When the sample enters the outer shell, the guide plate resets and seals the upper part of the outer shell, preventing dust from spilling out during the sieving process.

[0015] 2. This utility model uses a motor to drive the eccentric wheel to rotate and collide with the baffle, which in turn causes the baffle to move the filter cover back and forth, thereby allowing the sample inside the filter cover to vibrate and be sieved, thus improving the sieve efficiency of the sample.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-2 A sample screening device for sampling in the treatment of abandoned mines includes a shell 1, a protective mechanism 2 on the shell 1, a filter cover 3 slidably connected inside the shell 1, a support plate 4 fixedly connected inside the shell 1, a vibration mechanism 5 on the support plate 4, and four evenly distributed support legs 6 fixedly connected to the lower end of the shell 1.

[0023] Please see Figures 1-4The protective mechanism 2 includes guide plates 21. Two guide plates 21 are hinged to each other inside the outer shell 1. A baffle 22 is fixedly connected inside the outer shell 1. The baffle 22 contacts the guide plates 21 and seals the space between the guide plates 21 and the outer shell 1. A support plate 23 is fixedly connected inside the outer shell 1. A square rod 24 is slidably connected inside the support plate 23. A stop block is fixedly connected to the lower end of the square rod 24 and contacts the support plate 23. The stop block limits the movement of the square rod. A top block 25 is fixedly connected to the upper end of the square rod 24. The top block 25 is in contact with the guide plate 21. A spring 26 is provided on the outside of the square rod 24. One end of the spring 26 is fixedly connected to the top block 25, and the other end of the spring 26 is fixedly connected to the support plate 23. By setting the spring 26, the top block 25 can be easily reset. The spring 26 elastically pushes the top block 25 upward, thereby allowing the guide plate 21 to open and close automatically. When the sample enters the outer shell 1, the guide plate 21 resets and seals the upper end of the outer shell 1 to prevent dust from spilling out during the sieving process.

[0024] Please see Figures 1-3 The vibration mechanism 5 includes a baffle 51, which is fixedly connected inside the outer shell 1. An eccentric wheel 53 is fixedly connected to the upper end of the shaft of the motor 52. By setting the baffle 51 and the eccentric wheel 53 to cooperate, the vibration of the filter cover 3 is controlled. The motor 52 is fixedly installed in the middle of the lower end of the support plate 4. The shaft of the motor 52 passes through the support plate 4 and is rotatably connected to the support plate 4. A slide rod 54 is fixedly connected to the surface of the filter cover 3. The slide rod 54 is slidably connected to the outer shell 1. A compression spring 55 is fixedly connected to the surface of the slide rod 54. One end of the compression spring 55 is fixedly connected to the filter cover 3, and the other end of the compression spring 55 is fixedly connected to the outer shell 1. By setting the compression spring 55, the filter cover 3 can be easily reset. The motor 52 drives the eccentric wheel 53 to rotate and collide with the baffle 51, thereby causing the baffle 51 to drive the filter cover 3 to move back and forth, thereby allowing the sample inside the filter cover 3 to vibrate and sieve, improving the sieve efficiency of the sample.

[0025] The specific implementation process of this utility model is as follows: When in use, the motor 52 is started, and the motor 52 drives the eccentric wheel 53 to rotate. The eccentric wheel 53 rotates and collides with the baffle 51, which in turn causes the baffle 51 to move the filter cover 3 back and forth, thereby causing the filter cover 3 to vibrate. This allows the sample inside the filter cover 3 to vibrate and be sieved, improving the sieve efficiency of the sample. The sample is poured into the outer shell 1, and the guide plate 21 is squeezed by external force, which causes the guide plate 21 to deflect. The deflection of the guide plate 21 squeezes the top block 25, and the top block 25 squeezes the spring 26, causing the spring 26 to be compressed. When the sample falls from the top of the guide plate 21, the spring 26 returns to its original position, which causes the top block 25 to return to its original position and push the guide plate 21, thereby causing the two guide plates 21 to contact and close the upper end of the outer shell 1. The spring 26 elastically pushes the top block 25 up, which allows the guide plate 21 to open and close automatically. When the sample enters the outer shell 1, the guide plate 21 returns to its original position and closes the upper end of the outer shell 1, preventing dust from spilling out during the sieve process.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
