[0004] Based on the deficiencies in the aforementioned patents, we propose a magnetic separation and sorting device for mining materials that can screen and remove iron powder from minerals without affecting the quality of mineral production. Summary of the Invention

The fixed short rod is located behind the transverse crossbar. The second hinge rod is sleeved on the fixed short rod and is slidably connected to the fixed short rod.

[0011] Further explanation: It also includes a shaking mechanism for facilitating material unloading. The shaking mechanism includes a positioning rod, a limiting inclined rod, a lifting short column, a fixed frame, a shaking inclined plate, and shaking springs. The positioning rod is slidably connected to the right side of the front of the first discharge pipe, and the positioning rod is fixedly connected to the horizontal moving crossbar. The limiting inclined rod is rotatably connected to the front right side of the first discharge pipe, and the limiting inclined rod is in contact with the positioning rod. The lifting short column is slidably connected to the left side of the front of the first discharge pipe and the left side of the front of the second discharge pipe.

[0014] To further explain, it also includes a cover, with a threaded cover placed at the front of the air intake pipe.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In this invention, an appropriate amount of ore is poured in, the servo motor is started, and then the iron powder is adsorbed onto the screening cylinder by the magnetic separator. The ore that is not adsorbed falls into the second discharge pipe through the screening cylinder and is discharged. At the same time, when the iron powder is reversed to the left, it falls into the first discharge pipe and is discharged. In this way, the iron powder in the ore can be screened and removed without affecting the quality of ore production.

[0017] 2. Under the action of the shaking mechanism of the present invention, the upper shaking inclined plate swings up and down to shake the iron powder in the first discharge pipe, while the lower shaking inclined plate swings up and down to shake the ore in the second discharge pipe. In this way, it can be avoided that the material is difficult to discharge from the first discharge pipe and the second discharge pipe.

[0018] 3. Under the action of the rolling mechanism of the present invention, the rolling inclined plate moves up and down in coordination with the fixed inclined plate to roll the ore. In this way, the ore volume can be avoided from being too large, which would affect the screening efficiency. Attached Figure Description

Detailed Implementation

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] Example 1

[0040] A magnetic separation and sorting device for mining materials, such as Figures 1-5As shown, it includes a support base frame 1, a feed square tube 2, a first discharge pipe 3, a second discharge pipe 4, a screening cylinder 5, a screening roller 6, a feeding mechanism 7, and a separating mechanism 8. The feed square tube 2 is connected to the upper right side of the support base frame 1. The screening cylinder 5 is connected to the left side of the feed square tube 2 by bolts. The first discharge pipe 3 is connected to the upper left side of the screening cylinder 5. The second discharge pipe 4 is connected to the lower left side of the screening cylinder 5. The feeding mechanism 7 is connected to the feed square tube 2, which can discharge ore. The separating mechanism 8 is connected between the feeding mechanism 7 and the screening cylinder 5, which can adsorb iron powder. The screening roller 6 is connected to the separating mechanism 8, which can separate the ore.

[0041] like Figure 2 and Figure 3 As shown, the feeding mechanism 7 includes a feeding belt assembly 71, a servo motor 72, a drive shaft 73, a positioning horizontal shaft 74, and a first transmission assembly 75. The servo motor 72 is fixedly connected to the rear right side of the feeding square tube 2. The drive shaft 73 is rotatably connected to the lower right side of the feeding square tube 2. The rear end of the drive shaft 73 is fixedly connected to the output shaft of the servo motor 72. The positioning horizontal shaft 74 is rotatably connected to the left side of the feeding square tube 2. The first transmission assembly 75 is connected between the rear of the positioning horizontal shaft 74 and the rear of the drive shaft 73. The first transmission assembly 75 consists of two pulleys and a belt. One pulley is installed at the rear of the positioning horizontal shaft 74, and the other pulley is installed at the rear of the drive shaft 73. The belt is wound between the two pulleys. The feeding belt assembly 71 is connected between the middle of the positioning horizontal shaft 74 and the middle of the drive shaft 73. The feeding belt assembly 71 consists of two pulleys and a belt. One pulley is installed at the middle of the positioning horizontal shaft 74, and the other pulley is installed at the middle of the drive shaft 73. The belt is wound between the two pulleys.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the material distribution mechanism 8 includes a fixed short shaft 81, a second transmission assembly 82, a fixed crossbar 83, and a magnetic separator 84. The fixed short shaft 81 is rotatably connected to the middle of the front part of the screening cylinder 5. The fixed short shaft 81 is fixedly connected to the screening roller 6. The second transmission assembly 82 is connected between the middle of the fixed short shaft 81 and the front part of the positioning crossbar 74. The second transmission assembly 82 consists of two pulleys and a belt. One pulley is installed in the middle of the fixed short shaft 81, and the other pulley is installed in the front part of the positioning crossbar 74. The belt is wound between the two pulleys. The fixed crossbar 83 is rotatably connected to the middle of the screening roller 6. The fixed crossbar 83 is fixedly connected to the rear part of the screening cylinder 5. The magnetic separator 84 is fixedly connected to the middle of the fixed crossbar 83. The magnetic separator 84 is located inside the screening roller 6.

[0043] First, the operator connects the first discharge pipe 3 and the second discharge pipe 4 to external conveying pipes. Then, an appropriate amount of ore is poured onto the feed belt assembly 71 through the feed square pipe 2. The servo motor 72 is started, which drives the drive shaft 73 to reverse. The reverse rotation of the drive shaft 73 drives the first transmission assembly 75 to reverse, which in turn drives the positioning horizontal shaft 74 to reverse. Thus, the reverse rotation of the drive shaft 73, in conjunction with the reverse rotation of the positioning horizontal shaft 74, drives the feed belt assembly 71 to reverse. The reverse rotation of the feed belt assembly 71 causes the ore to move to the left. The ore moves to the left and comes into contact with the screening cylinder 5. Subsequently, the iron powder is adsorbed onto the screening cylinder 5 by the magnetic separator 84, and the unadsorbed ore... The material falls through the screening cylinder 5 and is discharged into the second discharge pipe 4. At the same time, the reversal of the positioning horizontal shaft 74 also drives the second transmission component 82 to reverse. The reversal of the second transmission component 82 drives the fixed short shaft 81 to reverse, which in turn drives the screening cylinder 5 to reverse. The reversal of the screening cylinder 5 drives the iron powder to reverse. When the iron powder reverses to the left, the magnetic separator 84 no longer attracts the iron powder, and the iron powder falls into the first discharge pipe 3 and is discharged. This process is repeated to continuously screen the ore. After all the ore is screened, the servo motor 72 is turned off, the drive shaft 73 stops driving the positioning horizontal shaft 74 to reverse through the first transmission component 75, and the screening cylinder 5 also stops reversing.

[0044] Example 2

[0045] Based on Example 1, such as Figures 6-10 As shown, it also includes a cleaning mechanism 9, which includes a drive gear 91, a first driven gear 92, a rotating seat 93, a first hinge rod 94, a transverse crossbar 95, a second hinge rod 96, a cleaning brush 97, a fixed crossbar 98, and a fixed short rod 99. The drive gear 91 is fixedly connected to the front of the fixed short shaft 81. The rotating seat 93 is rotatably connected to the upper left side of the front of the screening cylinder 5. The first driven gear 92 is fixedly connected to the front of the rotating seat 93 and meshes with the drive gear 91. The first hinge rod 94 is rotatably connected to the middle of the rotating seat 93. The upper right front side of the first discharge pipe 3 is slidably connected to... There is a horizontal moving bar 95. The front part of the horizontal moving bar 95 is rotatably connected to the upper part of the first hinge rod 94. The lower part of the horizontal moving bar 95 is rotatably connected to the second hinge rod 96. The upper right side of the first discharge pipe 3 is fixedly connected to a fixed crossbeam 98. A cleaning brush 97 is slidably connected to the fixed crossbeam 98. The cleaning brush 97 can clean the screening roller 6. The cleaning brush 97 is rotatably connected to the second hinge rod 96. The upper right front side of the first discharge pipe 3 is fixedly connected to a fixed short rod 99. The fixed short rod 99 is located behind the horizontal moving bar 95. The second hinge rod 96 is sleeved on the fixed short rod 99. The second hinge rod 96 and the fixed short rod 99 are slidably connected.

[0046] like Figure 6 , Figure 11 and Figure 12As shown, it also includes a shaking mechanism 10, which includes a positioning rod 101, a limiting inclined rod 102, a lifting short column 103, a fixed frame 104, a shaking inclined plate 105, and a shaking spring 106. The positioning rod 101 is slidably connected to the front right side of the first discharge pipe 3, and the positioning rod 101 is fixedly connected to the transverse moving crossbar 95. The limiting inclined rod 102 is rotatably connected to the right front side of the first discharge pipe 3, and the limiting inclined rod 102 is in contact with the positioning rod 101. The lifting short column 103 is slidably connected to the front left side of the first discharge pipe 3 and the front left side of the second discharge pipe 4. The upper lifting short column 103 contacts the positioning pole 101, and a fixed frame 104 is fixed between the upper and lower lifting short columns 103. The right side of the first discharge pipe 3 and the right side of the second discharge pipe 4 are rotatably connected to the shaking inclined plate 105. The shaking inclined plate 105 can prevent the material from getting stuck. The upper and lower lifting short columns 103 contact the upper and lower shaking inclined plates 105 respectively. Shaking springs 106 are fixedly and evenly spaced between the bottom left side of the upper shaking inclined plate 105 and the bottom left side of the first discharge pipe 3. Shaking springs 106 are also fixedly and evenly spaced between the bottom left side of the lower shaking inclined plate 105 and the bottom left side of the second discharge pipe 4.

[0047] like Figures 13-17 As shown, it also includes a compaction mechanism 11, which includes a drive gear 111, a second driven gear 112, a synchronous belt assembly 113, transmission short rods 114, a compaction inclined plate 115, a telescopic round seat 116, a buffer spring 117, and a fixed inclined plate 118. The drive gear 111 is fixedly connected to the front of the drive shaft 73. The second driven gear 112 is rotatably connected to the lower right side of the front of the feed square tube 2. The second driven gear 112 meshes with the drive gear 111. Two transmission short rods 114 are rotatably connected to the upper right side of the front of the feed square tube 2. The synchronous belt assembly 113 connects the front of the two transmission short rods 114 to the rear of the second driven gear 112. The synchronous belt assembly 113 consists of three synchronous pulleys and a synchronous belt. Two synchronous pulleys are installed at the front of two short transmission rods 114, and the other synchronous pulley is installed at the rear of the second driven gear 112. The synchronous belt is wound between the three synchronous pulleys. Telescopic round seats 116 are fixedly connected to the rear of both short transmission rods 114. A crushing inclined plate 115 is rotatably connected between the left sides of the two telescopic round seats 116. Buffer springs 117 are fixedly connected inside both telescopic round seats 116. A fixed inclined plate 118 is fixedly connected to the right side of the feed square tube 2. The crushing inclined plate 115 can contact the fixed inclined plate 118 when it moves downward. The crushing inclined plate 115 and the fixed inclined plate 118 can crush the ore.

[0048] When the servo motor 72 is working, the fixed short shaft 81 reverses, driving the drive gear 91 to reverse, which in turn drives the first driven gear 92 to rotate forward. The first driven gear 92 rotates forward, driving the rotating seat 93 to rotate forward. The rotating seat 93 rotates forward, driving the first hinge rod 94 to move left and right. The left and right movement of the first hinge rod 94 drives the horizontal moving bar 95 to move left and right. The left and right movement of the horizontal moving bar 95 drives the cleaning brush 97 to move back and forth through the second hinge rod 96. Subsequently, when the screening cylinder 5 reverses, causing the iron powder to reverse to the left, the magnetic separator 84 no longer adsorbs the iron powder. The cleaning brush 97 moves back and forth to scrape off the iron powder. After all the minerals are screened, the servo motor 72 is turned off, the fixed short shaft 81 stops driving the first driven gear 92 to rotate forward through the drive gear 91, and the cleaning brush 97 also stops moving back and forth. In this way, the iron powder can be prevented from falling off the screening cylinder 5.

[0049] When the servo motor 72 is working, the horizontal movement bar 95 moves left and right, causing the positioning rod 101 to move left and right. The left and right movement of the positioning rod 101 causes the limiting inclined rod 102 to swing up and down. The swinging up and down of the limiting inclined rod 102 causes the upper lifting short column 103 to move up and down. The swinging up and down of the upper lifting short column 103 causes the upper shaking inclined plate 105 to swing up and down. The upper shaking spring 106 buffers the upper shaking inclined plate 105. In turn, the swinging up and down of the upper shaking inclined plate 105 shakes the iron powder in the first discharge pipe 3. At the same time, the up and down movement of the upper lifting short column 103 also causes the fixed frame 104 to move up and down, fixing... The vertical movement of the upright frame 104 causes the lower lifting column 103 to move up and down. The vertical movement of the lower lifting column 103 causes the lower shaking inclined plate 105 to swing up and down. The lower shaking spring 106 provides a buffer for the lower shaking inclined plate 105. The swinging of the lower shaking inclined plate 105 shakes the ore in the second discharge pipe 4. After all the ore is screened, the servo motor 72 is turned off, and the horizontal moving bar 95 stops swinging up and down through the positioning upright 101, which drives the limiting inclined bar 102 to swing up and down. The upper and lower shaking inclined plates 105 on both sides stop swinging up and down. In this way, it can be avoided that the material is difficult to be discharged from the first discharge pipe 3 and the second discharge pipe 4.

[0050] When the ore is poured into the feed square tube 2, the servo motor 72 is started, and the drive shaft 73 reverses, driving the drive gear 111 to reverse. The reverse rotation of the drive gear 111 drives the second driven gear 112 to rotate forward. The forward rotation of the second driven gear 112 drives the synchronous belt assembly 113 to rotate forward. The forward rotation of the synchronous belt assembly 113 drives the left and right transmission rods 114 to rotate forward. The forward rotation of the left and right transmission rods 114 drives the left and right telescopic round seats 116 to rotate forward. The left and right telescopic round seats 116 drive the rolling inclined plate 115 to move up and down. The left and right buffer springs 117 play a buffering role. The up and down movement of the rolling inclined plate 115, together with the fixed inclined plate 118, crushes the ore. After all the ore is screened, the servo motor 72 is turned off, the drive shaft 73 stops rotating forward through the drive gear 111 and the second driven gear 112, and the rolling inclined plate 115 also stops moving up and down. In this way, the ore volume is avoided from being too large, which would affect the screening efficiency.

[0051] Example 3

[0052] Based on Examples 1 and 2, such as Figure 13 and Figure 18 As shown, it also includes a blowing mechanism 12, which includes an air blowing pipe 121 and an air inlet pipe 122. The air blowing pipe 121 is embedded in the middle of the upper part of the screening cylinder 5. The air blowing pipe 121 can blow the material down. The air inlet pipe 122 is connected to the middle of the air blowing pipe 121.

[0053] It also includes a cover 123, with the cover 123 threadedly placed at the front of the air intake pipe 122.

[0054] First, the operator opens the cover 123 and connects the air inlet pipe 122 to the external blower. When the device is in use, the blowing pipe 121 blows air onto the screening cylinder 5, and then blows the unadsorbed material into the second discharge pipe 4. When the device is no longer needed, the air inlet pipe 122 is stopped, and then the cover 123 is closed. This can increase the efficiency of mineral screening.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
