[0002] Currently, high-frequency vibrating screens have been widely used in the dehydration or classification of fine-grained materials, such as coarse coal slime dehydration, tailings dehydration, sand and gravel dehydration, and chemical and building material raw material classification. High-frequency vibrating screens are divided into three types: electromagnetic vibration high-frequency screens, mechanical vibration high-frequency screens, and electromagnetic and mechanical composite vibration high-frequency screens. They each have their own advantages and disadvantages.

[0003] According to a disclosed high-frequency vibrating screen for dehydrating iron ore concentrate (publication number: CN 214763778 U), it includes a support frame, the main structure of which is a rectangular frame consisting of two transverse support beams and two longitudinal support beams, and two vibrating assemblies are respectively provided on each transverse support beam;

[0004] However, in the above design, it is difficult to achieve that when the iron ore concentrate is sifted, the iron ore concentrate cannot fall downwards through the cooperation of the support frame, rectangular frame and other components.

When the iron ore powder is sieved by the screen plate, the sieved iron ore powder falls downward, and the baffle fixed at the bottom of the screen plate can block the sieved iron ore powder to prevent the small amount of iron ore powder from being blown around by the wind, thereby improving the work efficiency of the staff, ensuring that the iron ore powder is not blown around, and saving costs.

[0018] 2. In the utility model, the blocks, chute, vibration plate, connecting rod and other components cooperate with each other, so that when the speed of the motor increases, the motor can drive the movement of each component to accelerate, so that the force gear drives the block to rotate clockwise faster, and the contact between the block and the arc surface of the connecting rod becomes faster, thereby making the sliding speed of the vibration plate on the inner wall of the chute faster, so that when the sieved iron powder falls on the vibration plate, it is accelerated to vibrate and sieve out the unsieved particles in the iron powder, so that the iron powder is completely sieved and falls to the bottom of the vibration plate.

[0026] The following will be combined with 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.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment proposes a high-frequency screen for iron ore concentrate with automatic amplitude adjustment, including a support frame 1 and a button 2, the button 2 is arranged on the front side of the support frame 1, the inner wall of the support frame 1 is fixedly connected with a connecting plate 3, the inner wall of the connecting plate 3 is fixedly connected with a fixing plate 4, the bottom of the support frame 1 is fixedly connected with a support plate 5, and a screening device 6 is arranged inside the connecting plate 3; the screening device 6 includes a motor 61, the motor 61 is fixed through the front side of the support frame 1, the end of the output shaft of the motor 61 is fixedly connected with a reciprocating screw 62, the circumferential surface of the reciprocating screw 62 is threadedly connected with a reciprocating wire sleeve 63, the circumferential surface of the reciprocating wire sleeve 63 is fixedly connected with a push plate 64, and the circumferential surface of the reciprocating wire sleeve 63 is fixedly connected with a force-bearing rod 65.

[0029] A groove 66 is provided at the top of the fixed plate 4, and a spring 67 is fixedly connected to the inner wall of the groove 66. A slider 68 is fixedly connected to the inner wall of the spring 67 away from the groove 66. A sieve plate 69 is fixedly connected to the top of the slider 68, and a baffle 610 is fixedly connected to the top of the sieve plate 69. This design is advantageous in that when the slider 68 is forced to slide on the inner wall of the groove 66, the slider 68 can be reset by the elastic force of the spring 67 after losing the thrust.

[0030] The force-bearing rod 65 is slidably connected to the inner wall of the connecting plate 3. Two springs 67 are provided, and the initial state of the spring 67 is set to a relaxed state. This design is conducive to the force-bearing rod 65 sliding on the inner wall of the connecting plate 3 and can limit the reciprocating wire sleeve 63.

[0031] In this embodiment, when the staff starts working, first, the iron ore powder needs to be poured into the inside of the sieve plate 69, and the external power supply is turned on to start the motor 61, thereby prompting the reciprocating screw 62 to rotate clockwise. When the reciprocating screw 62 rotates clockwise, the reciprocating wire sleeve 63 is forced to make a reciprocating linear motion on the circumferential surface of the reciprocating screw 62. When the reciprocating wire sleeve 63 makes a reciprocating linear motion, it drives the push plate 64 to make a reciprocating linear motion, thereby intermittently knocking on the positive side of the sieve plate 69, so that the sieve plate 69 is subjected to force through the elasticity of the spring 67 and the slider 68 on the inner wall of the groove 66. Slide, so that the sieve plate 69 slides on the inner wall of the connecting plate 3. When the sieve plate 69 slides on the inner wall of the connecting plate 3, the sieve plate 69 can sieve the iron ore powder inside, so that the iron ore powder is sieved and the large impurities in the iron ore powder are sieved first. When the iron ore powder is sieved by the sieve plate 69, the sieved iron ore powder falls downward. The baffle 610 fixed at the bottom of the sieve plate 69 can block the sieved iron ore powder to prevent the small amount of iron ore powder from being blown around by the wind, thereby improving the work efficiency of the staff, ensuring that the iron ore powder is not blown around, and saving costs.

[0032] Example 2

[0033] like Figures 3 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, a second embodiment is also proposed. A vibration device 7 is provided at the bottom of the connecting plate 3, and the vibration device 7 includes a worm 71. The worm 71 is fixedly connected to the circumferential surface of the reciprocating screw 62. The top of the support plate 5 is rotatably connected to a rotating shaft 72. The circumferential surface of the rotating shaft 72 is fixedly connected to a worm wheel 73. The circumferential surface of the rotating shaft 72 is fixedly connected to a transmission gear 74. Such a design is conducive to driving the worm 71 to rotate clockwise when the reciprocating screw 62 rotates clockwise.

[0034] The top of the support plate 5 is rotatably connected to a rotating rod 75, the circumferential surface of the rotating rod 75 is fixedly connected to a force-bearing gear 76, the circumferential surface of the force-bearing gear 76 is fixedly connected to a blocking block 77, a sliding groove 78 is provided on the side of the connecting plate 3, the inner wall of the sliding groove 78 is slidably connected to a vibration plate 79, and the bottom of the vibration plate 79 is fixedly connected to a connecting rod 710. This design is conducive to driving the rotating rod 75 to rotate clockwise when the force wheel of the force-bearing gear 76 rotates clockwise.

[0035] The worm wheel 73 is meshed with the worm 71 , and the force gear 76 is meshed with the transmission gear 74 . The worm wheel 73 is located directly above the transmission gear 74 . This design is beneficial for forcing the transmission gear 74 to rotate counterclockwise through the rotating shaft 72 when the worm wheel 73 is forced to rotate counterclockwise.

[0036] One end of the block 77 is set to an adaptive arc surface, and one end of the connecting rod 710 is set to an arc surface. The arc surface at one end of the block 77 contacts the arc surface at one end of the connecting rod 710. There are several block blocks 77, and the circular array is on the circumferential surface of the force-bearing gear 76. This design is beneficial for when the block 77 and the arc surface of the connecting rod 710 contact each other, the connecting rod 710 can be forced to push upward.

[0037] The side cross-section of the sieve plate 69 is set to be concave, and the side of the sieve plate 69 is slidably connected to the inner wall of the connecting plate 3. This design is beneficial when the sieve plate 69 is subjected to force to slide on the inner wall of the groove 66 through the slider 68. The side of the sieve plate 69 is slidably connected to the inner wall of the connecting plate 3, which can play a certain supporting role for the sieve plate 69.

[0038] The side cross-section of the baffle 610 is set to be hollow, the reciprocating wire sleeve 63 is located on the side of the baffle 610, and the side cross-section of the vibrating plate 79 is set to be special-shaped. This design is beneficial for the baffle 610 fixed at the bottom of the screen plate 69 to block the iron ore powder after screening when it falls downward.

[0039] The side section of the connecting plate 3 is set to be hollow, the reciprocating screw 62 runs through the front side of the connecting plate 3, and the button 2 is electrically connected to the motor 61. This design is beneficial for the staff to adjust the speed of the motor 61 through the button 2 to achieve the function of automatic amplitude adjustment.

[0040] In this embodiment, in the screening device 6, after the iron ore fines are screened, the particles in the iron ore fines are not completely screened. When the reciprocating screw 62 is forced to rotate clockwise, the worm 71 is forced to rotate clockwise, thereby forcing the worm wheel 73 meshing with the worm 71 to rotate counterclockwise through the rotating shaft 72. When the worm wheel 73 drives the rotating shaft 72 to rotate counterclockwise, the transmission gear 74 fixed on the circumferential surface of the rotating shaft 72 is forced to rotate counterclockwise. The wheels 76 mesh with each other. When the transmission gear 74 rotates counterclockwise, the force-bearing gear 76 is forced to drive the rotating rod 75 to rotate clockwise. When the force-bearing gear 76 rotates clockwise, the block 77 arranged in a circumferential array on the circumferential surface of the force-bearing gear 76 also rotates clockwise. When the block 77 rotates clockwise, it touches the arc surface of the connecting rod 710 fixed to the bottom of the vibration plate 79, so that the connecting rod 710 is forced to push upward. When the connecting rod 710 pushes upward, the vibration plate 79 can be forced. When the gear 76 is turned on the left, the gear 77 is rotated in a clockwise direction, and the stop block 77 is rotated in a clockwise direction, so that the stop block 77 contacts the arc surface of the connecting rod 710 faster, thereby making the vibration plate 79 slide faster on the inner wall of the chute 78. When the arc surface of the connecting rod 710 does not contact the block 77, the connecting rod 710 moves downward when it loses force, thereby driving the vibration plate 79 to move downward and place it at the bottom of the chute 78. The staff controls the speed of the motor 61 by pressing the button 2 set on the positive side of the support frame 1. When the speed of the motor 61 increases, the motor 61 can drive the movement of each component to accelerate, so that the force-bearing gear 76 drives the block 77 to rotate clockwise faster, so that the block 77 contacts the arc surface of the connecting rod 710 faster, thereby making the sliding speed of the vibration plate 79 on the inner wall of the chute 78 faster, so that when the iron powder after being screened falls on the vibration plate 79, it is accelerated to vibrate and screen out the unscreened particles in the iron powder, so that the iron powder is completely screened and falls to the bottom of the vibration plate 79. If the speed of the motor 61 is lowered by the staff, the movement of each component will also slow down, realizing the effect of automatically adjusting the amplitude and improving work efficiency.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
