DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-Figure 8 As shown, the present invention is a processing device for crushing and screening mining raw materials, comprising a processing box 1, a crushing roller 33, a conveying shaft 14 and a conveyor belt 13; and also comprising a barrier cleaning unit arranged on the processing box 1; The crushing rollers 33 are provided with two and are symmetrically rotated and arranged in the processing box 1; The conveying shaft 14 is equidistantly and evenly rotatably arranged in the processing box 1; The conveyor belt 13 is sleeved on the conveyor shaft 14; The barrier cleaning unit is arranged on the processing box 1, and includes a driving component 41, a barrier component 42, a screening component 43 and a cleaning component 44; the driving component 41 drives the barrier component 42 to rise and fall; the driving component 41 drives the screening component 43 to vibrate; the driving component 41 drives the cleaning component 44 to move; The ore raw materials mined from the mine are transported into the processing box 1 by a transport machine, and the ore raw materials are crushed by the crushing roller 33. During the crushing, the driving component 41 drives the baffle component 42 to move up and down, and the crushed ore raw materials fall into the bottom of the processing box 1 and are screened by the screening component 43. At the same time, the cleaning component 44 also cleans the screening component 43. First, the ore raw materials mined from the mine are transported to the processing box 1 by the transport equipment. At this time, the driving component 41 will make the barrier component 42 descend so that the transport machinery can place the ore raw materials to be crushed into the processing box 1. After the ore raw materials enter the processing box 1, the driving component 41 will make the barrier component 42 rise. At this time, the crushing roller 33 in the processing box 1 will also crush the ore raw materials. By setting the barrier component 42, when the crushing roller 33 crushes the ore raw materials, the ore raw materials will not fly out of the processing box 1 due to the strong squeezing of the crushing roller 33 on the ore raw materials, causing the phenomenon of the machinery or personnel being hit; The ore material crushed by the crushing roller 33 will fall to the bottom of the processing box 1 and fall onto the screening component 43. The driving component 41 drives the screening component 43 to vibrate, so that the screening component 43 can classify the crushed ore material according to different particle sizes. The ore material with fine particle size will fall onto the conveyor belt 13 at the bottom through the screening component 43. The conveyor shaft 14 drives the conveyor belt 13 to send the ore material with fine particle size out of the processing box 1, and the coarse particle size is blocked above the screening component 43. The blocked coarse-grained ore materials will stay above the screening component 43. At this time, the cleaning component will clean and push, and push the coarse-grained ore materials staying above the screening component 43 out of the processing box 1. The cleaning component 44 will also clean the screening component 43 while pushing, to prevent the fine-grained ore materials from clogging the screening component 43, causing the fine-grained ore materials to be unable to pass through the screening component 43.

[0021] See also Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the driving assembly 41 includes an L-shaped plate 15, a connecting shaft 18, a driving gear 17, a driving motor 16, a driving shaft 3, a matching gear 24 and a lifting gear 2; The barrier assembly 42 includes a support plate 9, a limiting column 10, a blocking block 8 and a lifting gear plate 7; Among them, the L-shaped plate 15 is fixedly arranged on one side of the processing box 1; the connecting shaft 18 is rotatably arranged on the processing box 1, and the other end of the connecting shaft 18 is rotatably connected to the L-shaped plate 15; the driving motor 16 is fixedly arranged on the L-shaped plate 15, and the driving motor 16 is connected to the connecting shaft 18; the driving gear 17 is fixedly arranged on the connecting shaft 18; the driving shaft 3 is rotatably arranged on the processing box 1, and both ends of the driving shaft 3 pass through the processing box 1; the matching gear 24 is fixedly arranged on the driving shaft 3, and the matching gear 24 is meshed with the driving gear 17; the lifting gear 2 is provided with two, and is respectively fixedly arranged at both ends of the driving shaft 3; The support plate 9 is fixedly arranged on the processing box 1; two support plates 9 are provided and symmetrically arranged at both ends of the processing box 1; the limiting column 10 is fixedly arranged on the top of the support plate 9; the blocking block 8 is slidably arranged on the limiting column 10; the lifting gear plate 7 is fixedly arranged on the blocking block 8, and the lifting gear plate 7 is meshed with the lifting gear 2; The connecting shaft 18 on the L-shaped plate 15 is driven to rotate by the driving motor 16. The rotating connecting shaft 18 will drive the driving gear 17 to rotate. The rotating driving gear 17 will mesh with the matching gear 24 on the driving shaft 3, so that the driving shaft 3 and the matching gear 24 can rotate. The rotation of the driving shaft 3 will drive the lifting gear 2 to rotate. The rotating lifting gear 2 will make the lifting gear plate 7 rise and fall. The lifting and falling of the lifting gear plate 7 will make the shielding plate slide on the limiting column 10 on the support plate 9. There is a blocking buckle on the limiting column 10, which can prevent the shielding plate from slipping off when sliding on the limiting column 10. Because the lifting gear 2 is set to half teeth, when the lifting gear 2 rotates to the side without teeth, the lifting gear plate 7 will lose an upward force, so that the shielding block 8 will move downward. When the shielding plate slides and rises on the limiting column 10, it can not only prevent the transportation machinery from delivering the ore raw materials into the processing box 1, but also prevent the ore raw materials from flying out during crushing.

[0022] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the barrier assembly 42 further includes a fixing slot 26, a support column 30, a first special-shaped block 31, a second special-shaped block 32, a limiting block 21, a moving shaft 28, a clamping block 27 and a rebound spring 29; Among them, the fixed groove 26 is opened on the blocking block 8; the fixed groove 26 is provided with two and symmetrically arranged on the blocking block 8; the support column 30 is fixedly provided in the fixed groove 26; the first special-shaped block 31 is fixedly provided on the support column 30; the second special-shaped block 32 is slidably provided on the support column 30, and the second special-shaped block 32 is located below the first special-shaped block 31; the limiting block 21 is fixedly provided on the processing box 1, and the moving shaft 28 is slidably provided in the limiting block 21; the clamping block 27 is fixedly provided at one end of the moving shaft 28; the rebound spring 29 is sleeved on the moving shaft 28, and the rebound spring 29 is located in the limiting block 21; The lifting of the shielding plate will make the support column 30, the first special-shaped block 31 and the second special-shaped block 32 in the fixed groove 26 move upward together with the shielding plate. When the support column 30 and the first special-shaped block 31 move to the block 27 on the limiting block 21, because the first special-shaped block 31 is a cone shape, the block 27 will be squeezed, so that the rebound spring 29 and the moving shaft 28 on the block 27 move backward. When the first special-shaped block 31 is moved out, the rebound spring 29 will push the block 27 and the moving shaft 28 outward. At this time, the shielding block 8 will not move upward, and the shielding block 8 will move downward. In this way, the block 27 will jam the first special-shaped block 31 so that the shielding block 8 will no longer move downward. When the lifting gear 2 rotates again and engages with the lifting tooth plate 7, the blocking block 8 will rise again. At this time, the block 27 will be squeezed backward by the second special-shaped block 32. Then, after the lifting gear 2 is no longer in contact with the lifting tooth plate 7, the blocking block 8 will drop. At this time, the block 27 will drive the second special-shaped block 32 to move, so that the first special-shaped block 31 and the second special-shaped block 32 are combined into a cylinder, so that the block 27 will be separated from the first special-shaped block 31 and the second special-shaped block 32, so that the blocking block 8 can move downward smoothly, so that the handling machinery can smoothly deliver the ore raw materials into the processing box 1.

[0023] See also Figure 1 , Figure 2 and Figure 6 As shown, the screening assembly 43 includes a screening plate 12, a screening column 38, a screening block 39, a screening spring 40 and a knocking block 36; The sub-screening block 39 is fixedly arranged in the processing box 1; four sub-screening blocks 39 are provided, and two are symmetrically arranged in a group in the processing box 1; the sub-screening column 38 is slidably arranged on the sub-screening block 39; the sieve plate 12 is fixedly arranged on the top of the sub-screening column 38; the sub-screening spring 40 is sleeved on the sub-screening column 38, and the two ends of the sub-screening spring 40 are respectively fixedly connected to the sub-screening block 39 and the sub-screening column 38; the knocking block 36 is fixedly arranged on the driving shaft 3; The crushed ore material will fall onto the sieve plate 12, and the driving shaft 3 will drive the knocking block 36 to rotate. The rotating knocking block 36 will lift the sieve plate 12, allowing the screening column 38 on the sieve plate 12 to slide on the screening block 39. The movement of the screening column 38 will squeeze the screening spring 40. When the knocking block 36 is separated from the sieve plate 12, the screening spring 40 will pull the screening column 38 and the sieve plate 12 back, so that the sieve plate 12 will hit the screening block 39 to make the sieve plate 12 vibrate, thereby screening the ore material on the sieve plate 12.

[0024] See also Figure 2 and Figure 7 As shown, the cleaning assembly 44 includes a transverse groove 34, a sliding block 37, a cleaning plate 35 and a discharge port 11; The transverse groove 34 is provided in the processing box 1; two transverse grooves 34 are provided and symmetrically arranged in the processing box 1; the sliding block 37 is slidably provided in the transverse groove 34; the cleaning plate 35 is slidably provided on the sliding block 37; the discharge port 11 is provided at one side of the processing box 1; The sliding block 37 slides in the transverse groove 34, thereby driving the cleaning plate 35 to move, allowing the cleaning plate 35 to push the large-particle ore raw materials and clean the screen plate 12. The cleaning plate 35 is slidably set on the sliding block 37. This is set so that when the screen plate 12 is lifted up, the cleaning plate 35 is stuck by the lifted screen plate 12, thereby causing damage to the screen plate 12 and the cleaning plate 35. Therefore, when the screen plate 12 is lifted up, the cleaning plate 35 is also lifted up and moved upward at the same time.

[0025] See also Figure 2 , Figure 7 and Figure 8 As shown, a fixed block 20 is fixedly connected to one side of the processing box 1; two fixed blocks 20 are provided and symmetrically arranged on the processing box 1; a fixed shaft 22 is fixedly connected to the fixed block 20; a transverse gear plate 19 is slidably connected to the fixed shaft 22; one side of the transverse gear plate 19 is fixedly connected to the sliding block 37; a push spring 23 is sleeved on the fixed shaft 22, and the two ends of the push spring 23 are respectively fixedly connected to the transverse gear plate 19 and the fixed block 20; a transverse gear 25 is fixedly connected to the drive shaft 3; the transverse gear 25 is meshed with the transverse gear plate 19; The transverse gear 25 is driven to rotate by the driving shaft 3, and the rotating transverse gear 25 is meshed with the transverse tooth plate 19, so that the transverse tooth plate 19 slides on the fixed shaft 22 on the fixed block 20 and compresses the push spring 23 on the fixed shaft 22. When the transverse tooth plate 19 slides, the cleaning plate 35 will also move. The transverse gear 25 is half-toothed, so when the transverse gear 25 rotates without teeth, the transverse tooth plate 19 will be pushed to the initial position by the push spring 23, and then the transverse gear 25 drives the transverse tooth plate 19 to move.

[0026] See also Figure 2 , Figure 3 and Figure 6 As shown, the knocking blocks 36 are provided in plurality and are evenly and equidistantly arranged on the driving shaft 3; The purpose of providing a plurality of knocking blocks 36 is to prevent the ore material from being too heavy, and the plurality of knocking blocks 36 can smoothly lift up the screen plate 12 .

[0027] See also Figure 1 As shown, one end of the crushing roller 33 is fixedly connected to a driven wheel 6; the driving shaft 3 is fixedly connected to a driving wheel 4; a belt 5 is sleeved on the driven wheel 6 and the driving wheel 4; The driving shaft 3 drives the driving wheel 4 to rotate, and the driving wheel 4 drives the driven wheel 6 to rotate through the belt 5, so that the crushing roller 33 in the processing box 1 can rotate to crush the ore raw materials.

[0028] The working principle of the present invention is as follows: first, the ore raw materials mined from the mine are transported to the processing box 1 by the transport equipment, and then the driving component 41 makes the baffle component 42 descend so that the transport machinery can place the ore raw materials to be crushed into the processing box 1. After the ore raw materials enter the processing box 1, the driving component 41 makes the baffle component 42 rise again, and then the crushing roller 33 in the processing box 1 will also crush the ore raw materials. By setting the baffle component 42, when the crushing roller 33 crushes the ore raw materials, the ore raw materials will not fly out of the processing box 1 due to the strong squeezing of the crushing roller 33 on the ore raw materials, causing the phenomenon of the machinery or personnel being hit; The ore material crushed by the crushing roller 33 will fall to the bottom of the processing box 1 and fall onto the screening component 43. The driving component 41 drives the screening component 43 to vibrate, so that the screening component 43 can classify the crushed ore material according to different particle sizes. The ore material with fine particle size will fall onto the conveyor belt 13 at the bottom through the screening component 43. The conveyor shaft 14 drives the conveyor belt 13 to send the ore material with fine particle size out of the processing box 1, and the coarse particle size is blocked above the screening component 43. The blocked coarse-grained ore materials will stay above the screening component 43. At this time, the cleaning component will clean and push, and push the coarse-grained ore materials staying above the screening component 43 out of the processing box 1. The cleaning component 44 will also clean the screening component 43 while pushing, to prevent the fine-grained ore materials from clogging the screening component 43, causing the fine-grained ore materials to be unable to pass through the screening component 43.

[0029] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
