[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a circulating crushing device for antimony ore in antimony ingot production, which has the following beneficial effects:

[0018] 1. The circulating crushing device of antimony ore in the production of antimony ingots drives the push plate to move back and forth left and right through the connection between the second connecting plate and the push rod. When the push plate slides to fit against the left wall of the storage hopper, the storage hopper is connected to the feeding port through the dust cover. The antimony ore in the storage hopper falls into the dust cover under the action of gravity. At this time, the antimony ore inside the storage hopper can block the dust to prevent the dust from flying out of the storage hopper. After that, the push plate moves to the right to push the antimony ore in the dust cover to the feeding port. The antimony ore passes through the feeding port and falls between the driven crushing roller and the driven crushing roller to complete the feeding. When the push plate moves to the right side of the storage hopper, the storage hopper and the feeding port can be separated to prevent the dust inside the crushing box from being discharged. This achieves the purpose of suppressing the dust from flying out of the feeding port.

[0019] 2. The circulating crushing device of antimony ore in the production of antimony ingots, through the rotation of the driven crushing roller and the active crushing roller, the crushing teeth 1 and the crushing teeth 2 crush the antimony ore, the crushed antimony ore falls on the screen plate, the antimony ore with smaller particle size passes through the screen hole and falls on the top of the inclined plate; the antimony ore with larger particle size is retained on the top of the screen plate; in the process of the horizontal plate reciprocating left and right, the screen plate is driven to reciprocate left and right through the connection of the L-shaped plate, so that the antimony ore on the top of the screen plate moves toward the driven crushing roller or the active crushing roller, and the antimony ore with larger particle size is pushed upward along the arc surface by the crushing teeth 1 or the crushing teeth 2, so that the antimony ore with larger particle size passes between the driven crushing roller and the active crushing roller again and is crushed again; and in the process of the crushing teeth 1 or the crushing teeth 2 pushing the antimony ore, the antimony ore hits the V-shaped end of the arc-shaped partition bar, and the antimony ore can also be crushed; thereby achieving the purpose of circulating crushing of the antimony ore and improving the processing efficiency;

[0020] 3. In the circulating crushing device of antimony ore in the production of antimony ingots, during the reciprocating movement of the screen plate, the antimony ore stuck in the screen hole is scooped up by the bottom edge of the boss to avoid the screen hole being blocked and ensure the screening effect; during the reciprocating movement of the horizontal plate, the sliding arm and the rack plate are driven to move back and forth through the connecting action of the connecting plate three, driving the threaded rod and the gear three to rotate back and forth, thereby driving the threaded tube to move back and forth up and down; the spring one is squeezed and contracted, and when the elasticity of the spring one breaks through the limiting action between the embedded column and the hemispherical groove, the fixed plate one moves upward rapidly under the elastic action of the spring one, knocks up the antimony ore on its upper surface, makes the antimony ore hit the bottom of the screen plate, and promotes the antimony ore stuck in the column to fall; thereby preventing the screen hole from being blocked and ensuring the stability of the screening effect.

[0037] In the description of the present application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 2A circulating crushing device for antimony ore in the production of antimony ingots, comprising a crushing box 100, a feeding port 101 is provided through the top of the crushing box 100, a discharge port 102 is provided at the lower right half of the crushing box 100, and enclosure assemblies 500 are welded to the left and right side walls of the upper half of the crushing box 100, and the two enclosure assemblies 500 and the front and rear side walls of the crushing box 100 are combined to form a crushing chamber. A driven crushing roller 200 and an active crushing roller 300 are rotatably connected between the front and rear side walls of the crushing chamber, and a rotating driving member 400 is provided between the ends of the driven crushing roller 200 and the active crushing roller 300; a screening plate assembly 600 is attached to the bottom of the two enclosure assemblies 500, and the screening plate assembly 600 is slidably connected to the crushing box 100, a feeding assembly 700 is provided at the top of the crushing box 100, and a guide assembly 800 is provided in the lower half of the crushing box 100.

[0040] See also Figure 3-Figure 4 The surface array of the driven crushing roller 200 is provided with crushing teeth 1 201, and the surface array of the active crushing roller 300 is provided with crushing teeth 2 301, and the crushing teeth 1 201 and the crushing teeth 2 301 are staggered in the front-to-back direction. Therefore, when the driven crushing roller 200 and the active crushing roller 300 rotate, the crushing teeth 1 201 and the crushing teeth 2 301 squeeze and crush the ore. The rotating driving member 400 includes a reducer 401 fixedly mounted on the back of the crushing box 100, the input end of the reducer 401 is fixedly mounted with a motor 402, the output end of the reducer 401 is fixedly mounted on the rear end of the active crushing roller 300, the front end of the driven crushing roller 200 is fixedly mounted with a gear 1 403, and the front end of the active crushing roller 300 is fixedly mounted with a gear 2 404, and the gear 1 403 and the gear 2 404 are meshed with each other. Thus, the active crushing roller 300 is driven to rotate by the reducer 401 and the motor 402, and the driven crushing roller 200 is driven to rotate by the meshing action of the gear 1 403 and the gear 2 404. The driven crushing roller 200 and the active crushing roller 300 rotate in opposite directions.

[0041] See also Figure 3-Figure 4The enclosure assembly 500 includes two bosses 501 welded on the left and right side walls of the crushing box 100. The two bosses 501 are provided with arc surfaces 502 on opposite sides. The bottom of the bosses 501 is a horizontal plane, and the horizontal plane is tangent to the arc surface 502. The screening plate assembly 600 is attached to the bottom of the boss 501. The arc centers of the two arc surfaces 502 coincide with the axes of the driven crushing roller 200 and the active crushing roller 300 respectively. The free end of the crushing tooth 1 201 is attached to the arc surface 502 on the left, and the free end of the crushing tooth 2 301 is attached to the arc surface 502 on the right. Therefore, after the antimony ore is put into the feeding port 101, it falls between the driven crushing roller 200 and the active crushing roller 300. The active crushing roller 300 rotates counterclockwise, and the driven crushing roller 200 rotates clockwise to crush the antimony ore. After the crushed antimony ore is screened by the screening plate assembly 600, the antimony ore with larger particle size is retained on the top of the screening plate assembly 600; then, the antimony ore with larger particle size is transferred to the upper part of the driven crushing roller 200 or the active crushing roller 300 along the arc surface 502 through the pushing action of the crushing teeth 2 301 and the crushing teeth 1 201. Afterwards, as the driven crushing roller 200 and the active crushing roller 300 rotate, the antimony ore is transferred again to between the driven crushing roller 200 and the active crushing roller 300, thereby crushing the antimony ore again.

[0042] The two arc-shaped surfaces 502 are both fixed with arc-shaped spacers 503 in an array, and the bottom ends of the arc-shaped spacers 503 are V-shaped. The arc-shaped spacers 503 on the left are used to space the crushing teeth 1 201 distributed front and back, and the arc-shaped spacers 503 on the right are used to space the crushing teeth 2 301 distributed front and back. When the crushing teeth 2 301 and the crushing teeth 1 201 transfer the antimony ore with larger particle size, part of the antimony ore will be stuck between two adjacent crushing teeth 1 201 or between two adjacent crushing teeth 2 301; thus, when the antimony ore with larger particle size follows the crushing teeth 1 201 or the crushing teeth 2 301 to move, it will hit the bottom end of the arc-shaped spacer 503, thereby crushing the antimony ore.

[0043] See also Figure 5-Figure 7 The screening plate assembly 600 includes a screening plate 601 attached to the bottom of the two enclosure assemblies 500, and the surface array of the screening plate 601 is penetrated with a screening hole 602, and the front and rear sides and the rear side of the screening plate 601 are fixedly installed with a slide bar 603, and the front inner wall and the rear inner wall of the crushing box 100 are both provided with a slide groove 103, and the slide bar 603 is slidably connected in the slide groove 103. Therefore, the screening effect can be guaranteed after the crushed antimony ore falls on the screening plate 601 by the screening plate 601 moving left and right along the slide groove 103. In addition, the antimony ore with a larger particle size will move left and right with the screening plate 601, so that the antimony ore can be transferred to the bottom of the driven crushing roller 200 or the active crushing roller 300, so that the crushing tooth 1 201 or the crushing tooth 2 301 can push the antimony ore to the arc surface 502.

[0044] Two L-shaped plates 604 are fixedly installed on the left side of the screen plate 601, and the L-shaped plates 604 are L-shaped. The horizontal part of the L-shaped plate 604 penetrates and is slidably connected to the crushing box 100. A horizontal plate 605 is fixedly installed on the top of the two L-shaped plates 604. A connecting plate 1 606 is fixedly installed at both ends of the horizontal plate 605. The connecting plate 1 606 is perpendicular to the horizontal plate 605. A vertical frame plate 607 is fixedly installed on the right end of the connecting plate 1 606. A rotating disk 608 is coaxially fixed at both ends of the driven crushing roller 200, one of which is fixed at the rear end of the driven crushing roller 200, and the other is fixedly installed at the front side of the gear 1 403. A sliding column 609 is fixedly installed at the eccentric part of the surface of the rotating disk 608, and the sliding column 609 is slidably connected in the vertical frame plate 607. Therefore, when the driven crushing roller 200 rotates, the rotating disk 608 is driven to rotate, and the sliding column 609 performs a circular motion. In this process, the slide column 609 slides in the vertical frame plate 607 and pushes the vertical frame plate 607 to move left and right. Under the connection of the connecting plate 606, the horizontal plate 605 is driven to move back and forth left and right. Then, the screen plate 601 is moved back and forth left and right through the connection of the L-shaped plate 604. Since part of the antimony ore will be stuck inside the screen hole 602, the bottom edge of the boss 501 shovels the antimony ore stuck in the screen hole 602 during the left and right movement of the screen plate 601, thereby preventing blockage.

[0045] See also Figure 6-Figure 7 The feeding assembly 700 includes a dust cover 701 fixedly mounted on the top of the crushing box 100. The right half of the dust cover 701 is connected to the feeding port 101. A storage hopper 702 is welded on the top of the left end of the dust cover 701. The storage hopper 702 is used to temporarily store antimony ore. A slot 703 and two plug holes 704 are opened on the left side of the storage hopper 702. The two plug holes 704 are located below the slot 703. A support plate 705 is slidably connected in the slot 703. The support plate 705 is attached to the top wall of the dust cover 701. A push plate 706 is fixedly mounted on the bottom of the right end of the support plate 705. The push plate 706 is attached to the top of the crushing box 100. Two push rods 707 are fixedly mounted on the left side of the push plate 706. The push rods 707 are slidably connected to the plug holes 704. A connecting plate 2 708 is fixedly mounted on the left end of the push rod 707. The bottom end of the connecting plate 2 708 is fixedly mounted on the top of the horizontal plate 605.

[0046] Thus, when the horizontal plate 605 moves back and forth, the push plate 706 and the support plate 705 move back and forth synchronously under the connection of the connecting plate 2 708 and the push rod 707. When the push plate 706 moves to the right side of the storage hopper 702, the storage hopper 702 and the feeding port 101 can be separated to prevent the dust inside the crushing box 100 from being discharged. When the push plate 706 slides to fit the left side wall of the storage hopper 702, the storage hopper 702 is connected to the feeding port 101 through the dust cover 701, and the antimony ore in the storage hopper 702 falls into the dust cover 701 under the action of gravity. At this time, the antimony ore inside the storage hopper 702 can block the dust and prevent the dust from flying out of the storage hopper 702. After that, the push plate 706 moves to the right, and the antimony ore in the dust cover 701 can be pushed to the feeding port 101 to complete the feeding.

The top of the sleeve 801 is slidably connected with a column 802. The top of the four columns 802 is fixedly mounted with an inclined plate 803. The inclined plate 803 is inclined, with the left side higher than the right side. The antimony ore screened by the screen plate 601 falls on the inclined plate 803 and moves to the discharge port 102 under the guidance of the inclined plate 803. A support is provided at the bottom of the inclined plate 803.

Two inverted L-shaped frames 808 are fixedly mounted on the bottom wall of the crushing box 100, and the inverted L-shaped frames 808 are in an inverted L shape. The vertical rods 804 penetrate and slide through the horizontal part of the inverted L-shaped frames 808, and the front and rear ends of the fixed plate 1 805 are respectively attached to the opposite sides of the two inverted L-shaped frames 808.

Therefore, under the elastic action of the second spring 811, the embedded column 810 fits on the hemispherical groove 812, so that the fixing plate 2 807 can stably maintain the hemispherical groove 812.

[0050] See also Figure 10-11 The lifting drive member 900 includes a connecting plate 3 901 fixedly mounted on the bottom of the horizontal plate 605, a sliding arm 902 fixedly mounted on the bottom of the connecting plate 3 901, the sliding arm 902 penetrates and slides and connects to the crushing box 100, a rack plate 903 fixedly mounted on the front side of the sliding arm 902, a support seat 904 and a shaft sleeve 905 fixedly mounted on the bottom wall of the crushing box 100, the sliding arm 902 is slidably connected to the support seat 904, and the sliding arm 902 is supported and guided by the support seat 904. Therefore, when the horizontal plate 605 moves back and forth, the sliding arm 902 and the rack plate 903 are driven to move back and forth synchronously under the connection of the connecting plate 3 901.

[0051] The shaft sleeve 905 is rotatably connected with a threaded rod 906, and a gear three 907 is fixedly installed on the threaded rod 906, and the rack plate 903 is meshed with the gear three 907. Therefore, when the rack plate 903 moves back and forth, the gear three 907 and the threaded rod 906 are driven to rotate back and forth.

[0052] A threaded tube 908 is fixed through the center of the second fixing plate 807, and the threaded tube 908 is threadedly connected to the threaded rod 906. A convex strip 909 is fixedly installed on the outer wall of the threaded tube 908, and a blocking block 911 is fixedly installed on the top of the convex strip 909. The blocking block 911 is located directly above the second fixing plate 807. A avoidance groove 910 is opened through the center of the first fixing plate 805, and the threaded tube 908 and the convex strip 909 are slidably connected to the avoidance groove 910. Therefore, when the threaded rod 906 reciprocates, the threaded tube 908 and the second fixing plate 807 are driven to reciprocate up and down.

[0053] When the threaded tube 908 and the second fixed plate 807 move upward, the threaded tube 908 and the convex strip 909 slide relative to the first fixed plate 805, the distance between the second fixed plate 807 and the first fixed plate 805 decreases, and the spring 1 806 is squeezed and contracted. When the elasticity of the spring 1 806 breaks through the limiting effect between the embedded column 810 and the hemispherical groove 812, the embedded column 810 slides to the inside of the mounting hole 809, and the first fixed plate 805 moves upward rapidly under the elastic effect of the first spring 806, thereby driving the inclined plate 803 to move upward rapidly until the first fixed plate 805 fits on the lower surface of the horizontal part of the inverted L-shaped frame 808. Thus, the antimony ore on the upper surface of the inclined plate 803 is knocked up by the upward movement of the inclined plate 803, so that the antimony ore hits the bottom of the screen plate 601, and the antimony ore stuck in the column 802 is promoted to fall. The antimony ore is knocked up by the inclined plate 803 to prevent the antimony ore from accumulating on the top of the inclined plate 803 and hindering the subsequent antimony ore from moving downward. Ensure the stability of discharge.

[0054] When in use, antimony ore is put into the storage hopper 702, and then the active crushing roller 300 is driven to rotate by the reducer 401 and the motor 402, and the driven crushing roller 200 is driven to rotate by the meshing action of the gear 1 403 and the gear 2 404, thereby driving the two turntables 608 to rotate, and the mounting holes 809 to make a circular motion, pushing the vertical frame plate 607, the connecting plate 1 606 and the horizontal plate 605 to move back and forth;

[0055] The push plate 706 is driven to move back and forth left and right through the connection between the connecting plate 2 708 and the push rod 707. When the push plate 706 slides to fit the left side wall of the storage hopper 702, the storage hopper 702 is connected to the feeding port 101 through the dust cover 701. The antimony ore in the storage hopper 702 falls into the dust cover 701 under the action of gravity. At this time, the antimony ore inside the storage hopper 702 can block the dust and prevent the dust from flying out of the storage hopper 702. After that, the push plate 706 moves to the right to push the antimony ore in the dust cover 701 to the feeding port 101. The antimony ore passes through the feeding port 101 and falls between the driven crushing roller 200 and the driven crushing roller 200, completing the feeding. When the push plate 706 moves to the right side of the storage hopper 702, the storage hopper 702 and the feeding port 101 can be separated to prevent the dust inside the crushing box 100 from being discharged.

[0056] The driven crushing roller 200 and the active crushing roller 300 rotate, and the crushing teeth 1 201 and the crushing teeth 2 301 crush the antimony ore. The crushed antimony ore falls on the screen plate 601, and the antimony ore with smaller particle size passes through the screen hole 602 and falls on the top of the inclined plate 803; the antimony ore with larger particle size is retained on the top of the screen plate 601;

[0057] During the reciprocating movement of the horizontal plate 605, the screen plate 601 is driven to reciprocate left and right through the connection of the L-shaped plate 604, so that the antimony ore on the top of the screen plate 601 moves toward the driven crushing roller 200 or the active crushing roller 300, and the antimony ore with larger particle size is pushed upward along the arc surface 502 through the crushing teeth 1 201 or the crushing teeth 2 301, so that the antimony ore with larger particle size passes again between the driven crushing roller 200 and the active crushing roller 300 for re-crushing; and during the process of the crushing teeth 1 201 or the crushing teeth 2 301 pushing the antimony ore, the antimony ore hits the V-shaped end of the arc-shaped partition bar 503, which can also crush the antimony ore;

[0058] During the reciprocating movement of the sieve plate 601, the antimony ore stuck in the sieve hole 602 is scooped up by the bottom edge of the boss 501, thus preventing the sieve hole 602 from being blocked and ensuring the screening effect.

[0059] During the reciprocating movement of the horizontal plate 605, the connecting plate 901 drives the sliding arm 902 and the rack plate 903 to reciprocate left and right, drives the threaded rod 906 and the gear 907 to rotate back and forth, and drives the threaded tube 908 to reciprocate up and down;

[0060] When the threaded tube 908 and the second fixed plate 807 move upward, the threaded tube 908 and the convex strip 909 slide relative to the first fixed plate 805, the distance between the second fixed plate 807 and the first fixed plate 805 decreases, and the spring 1 806 is squeezed and contracted. When the elasticity of the spring 1 806 breaks through the limiting effect between the embedded column 810 and the hemispherical groove 812, the embedded column 810 slides into the inside of the mounting hole 809, and the first fixed plate 805 moves upward rapidly under the elastic effect of the spring 1 806, thereby driving the inclined plate 803 to move upward rapidly until the first fixed plate 805 fits on the lower surface of the horizontal part of the inverted L-shaped frame 808. Thus, the antimony ore on the upper surface of the inclined plate 803 is knocked up by the upward movement of the inclined plate 803, so that the antimony ore hits the bottom of the screen plate 601, and the antimony ore stuck inside the column 802 is promoted to fall.

[0061] When the threaded tube 908 and the second fixed plate 807 move downward, the blocking block 911 fits against the top of the first fixed plate 805 and pulls the first fixed plate 805 downward, driving the inclined plate 803 to move downward; since the inclined plate 803 is inclined, the antimony ore gathers toward the upper right end of the inclined plate 803, and when the bottom end of the inclined plate 803 moves to below the bottom wall of the discharge port 102, the antimony ore is discharged through the discharge port 102.
