Description

Technical Field

[0001] The invention relates to the technical field of ore mining, in particular to a multi-stage partition crusher for ore mining and sorting. Background Art

[0002] In the process of ore mining, a crusher is needed to crush the mined ore so that the ore can be collected and used for other purposes. For example, a crusher sorting machine is used in mining with the publication number CN209772265U. It is worth noting that the above patent content only performs unified screening on the crushed ore. In the early stage of ore mining, the crushed ore is roughly divided into coarse ore blocks and fine ore particles. There is a big difference in the volume of the ore, and the fine ore particles (without crushing) are simultaneously merged into the same crushing area with the ore blocks, which not only causes the loss of fine ore and makes it difficult to contact with the crushing parts, but also easily increases the operating burden of the crushing parts and causes jamming.

[0003] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0004] The purpose of the present invention is to screen the ore before crushing by volume and pile them in different areas waiting for intermittent unloading.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0029] Example 1: Please refer to Figure 1 - Figure 7 As shown, a multi-stage partition crusher for ore mining and sorting includes a material collection frame 1, a material separation circular frame 2 is fixedly installed at the center of the top of the rear end inner wall of the material collection frame 1 through a connecting rod, and a feed trough is provided at the corner of the top surface of the material separation circular frame 2;

[0030] The bottom surface of the dividing circular frame 2 is located on the same side of the feeding trough and three groups of arc-shaped dividing troughs 1 are arranged at equal distances. An arc-shaped dividing trough 2 is arranged on the other side of the bottom surface of the dividing circular frame 2, and the width of the dividing trough 2 is three times the width of the arc-shaped dividing trough 1. A double-axis motor 201 is arranged on the front end surface of the dividing circular frame 2, and the rear end output shaft of the double-axis motor 201 extends to the inside of the dividing circular frame 2 and is fixedly installed with a support bar 202. A transmission wheel 1 203 is fixedly installed on the front end rotating shaft of the double-axis motor 201. A material guide table 3 is fixedly installed inside the material collection frame 1 and located at the bottom of the dividing circular frame 2, and the top surface of the material guide table 3 is a triangular structure with a high middle and low sides.

[0031] Pour the collected ores of different volumes into the dividing circular frame 2 through the feeding trough. The ores are first accumulated inside the dividing circular frame 2 and located on one side of the resisting bar 202 (on the same side of the arc-shaped dividing circular frame). Then, the dual-axis motor 201 is started to drive the resisting bar 202 to rotate counterclockwise first. The resisting bar 202 pushes several groups of ores to slide along the left inner wall of the dividing circular frame 2.

[0032] Among them, the finely crushed ore particles and the crushed stone particles whose volume is smaller than the slot of the arc-shaped material dividing groove 1 are discharged outward through the arc-shaped material dividing groove 1 and slide down the inclined surface of one side of the material guiding platform 3 until the bar 202 rotates to approach the feeding groove, and then the double-axis motor 201 is used to drive the bar 202 to rotate in the opposite direction, and the remaining unscreened coarse ore blocks are pushed to the arc-shaped material dividing groove 2 on the inner wall of the other side of the material dividing circular frame 2;

[0033] Since the slot width of the arc-shaped dividing trough No. 2 is greater than that of the arc-shaped dividing trough No. 1, the remaining ore blocks are forced to be discharged outward through the arc-shaped dividing trough No. 2 and slide to the inclined surface on the other side of the guide platform 3, so as to facilitate separate crushing according to the volume of the mined ore. The two types of ore flow are divided along the inclined surface of the guide platform 3 and wait to slide down to the corresponding advanced crushing mechanism 5 for zone crushing processing, so as to improve the ore crushing efficiency.

[0034] An intermittent material distribution mechanism 4 is arranged outside the material guide platform 3, and an advanced material breaking mechanism 5 is arranged at the bottom of the material collection frame 1;

[0035] Among them, the intermittent material distribution mechanism 4 includes two groups of concave material blocking frames 41, the two groups of material blocking frames 41 are respectively sleeved on the two sides of the material guide platform 3, and the upper and lower ends of the material blocking frames 41 extend to the upper and lower ends of the material guide platform 3 respectively, and the bottom positions of the front and rear ends between the two groups of material blocking frames 41 are fixedly installed with slides 42, and one end of the slide 42 extends to the outside of the material guide platform 3, and the two ends of the two groups of slides 42 are respectively provided with limiting grooves, and the front and rear end surfaces of the material guide platform 3 are fixedly installed with round shafts 43 at the middle sections of both sides, and the round shafts 43 are slidably connected to the limiting grooves;

[0036] A slide groove is arranged at the inner center of the front end slide plate 42, and a tooth groove is arranged on the inner wall at the bottom of the slide groove, and a limit gear 44 is meshed in the inner center of the slide groove, and the rear center rotating shaft of the limit gear 44 is rotatably connected with the front end surface of the guide table 3, and the front rotating shaft of the limit gear 44 extends to the outside of the slide groove and a transmission wheel 203 is also fixedly installed thereon, and a transmission belt is commonly connected between the upper and lower sets of transmission wheels 203.

[0037] The double-axis motor 201 drives the bar 202 to rotate counterclockwise, and drives the transmission wheel 203 at the front end of the double-axis motor 201 to rotate synchronously. Under the transmission action of the transmission belt, the other set of transmission wheels 203 and the limit gear 44 connected thereto are driven to rotate synchronously, and the limit gear 44 is engaged with the tooth groove at the inner wall of the slide groove, so that one end of the two sets of slide plates 42 jointly pulls one set of material blocking frames 41 (on the same side of the arc-shaped material distribution groove) to move to the side of the material guide table 3 and overlap and engage with the material guide table 3;

[0038] At this time, the fine ore particles discharged from the arc-shaped material distribution trough are blocked by the material blocking frame 41 and retained on the top slope of the material guide platform 3 to wait for centralized material discharge. At the same time, the other ends of the two sets of slides 42 jointly push the other set of material blocking frames 41 (on the same side of the arc-shaped material distribution trough) away from the side frame of the material guide platform 3;

[0039] After the fine particles are screened separately, the double-axis motor 201 is used again to drive the bar 202, the transmission wheel 203 and the limit gear 44 to rotate clockwise, the bar 202 pushes in the reverse direction, the coarse ore begins to be screened to the guide table 3, and the limit gear 44 meshes with the tooth groove again to realize the reverse transmission of the slide plate 42, and the two sets of blocking frames 41 are reversely driven;

[0040] Thus, the blocking frame 41 close to the same side of the arc-shaped material distribution trough is away from the material guide platform 3 to form a material discharge space, so that fine ore particles begin to be discharged. At the same time, the blocking frame 41 close to the same side of the second arc-shaped material distribution trough is close to the side of the material guide platform 3 to form a barrier for the discharge of coarse ore. This is repeated to achieve intermittent discharge of ore materials of different volumes, indirectly controlling the single crushing amount of ore, which is conducive to improving the multi-layer crushing efficiency of ore.

[0041] It is worth noting that if there is a blocking frame 41 (on the same side of the arc-shaped material distribution trough), some larger ore particles may get stuck inside. Therefore, during the reciprocating motion of the blocking frame 41, these ore particles are squeezed and crushed to reduce the burden of subsequent crushing.

[0042] Example 2: Please refer to Figure 5 , Figure 6 - Figure 7 As shown, the advanced material breaking mechanism 5 includes a vertical plate 51, which is fixedly mounted at the bottom center of the material guide platform 3, and inclined material receiving frames 52 are respectively arranged at the top of both sides of the vertical plate 51, and inclined material receiving frames 53 are respectively arranged at the bottom of both sides of the vertical plate 51, and the lower ends of the two sets of material receiving frames 52 are cross-hinged by hinge rods and are jointly sleeved on the outside of the vertical plate 51, and the end of the material receiving frame 52 close to the vertical plate 51 is provided with a concave card groove, and the higher ends of the two sets of material receiving frames 53 are cross-hinged by hinge rods and are jointly sleeved on the outside of the vertical plate 51;

[0043] The two groups of material receiving frames 1 52 and the two groups of material receiving frames 2 53 are symmetrical with respect to the central axis of the vertical plate 51, respectively. The material receiving frames 1 52 and 2 53 on the same side are symmetrical with respect to the central axis of the vertical plate 51. A pressure roller 1 54 is arranged at the middle section of the top surface of the two groups of material receiving frames 1 52, and a pressure roller 2 55 is arranged at the middle section of the top surface of the two groups of material receiving frames 2 53. The insides of the pressure rollers 1 54 and 2 55 are rotatably connected to the rear end inner wall of the material collection frame 1 through fixed and penetrating rotating rods, and the rear end rotating rods of the two groups of pressure rollers 1 54 are fixedly sleeved with transmission wheels 2 56, and a transmission belt is commonly sleeved between the two groups of transmission wheels 2 56, and a motor 1 57 is commonly arranged between the rear end of one group of transmission wheels 2 56 and the rear end inner wall of the corresponding material collection frame 1;

[0044] When the ore materials after preliminary screening slide to the corresponding inclined surfaces of the receiving frame 1 52, the motor 1 57 is started to first drive one set of transmission wheels 2 56 to rotate, and the other set of transmission wheels 2 56 is forced to rotate under the driving action of the transmission belt;

[0045] At the same time, the pressure roller 1 54 connected to the transmission wheel 2 56 also rotates, and crushes the crushed stone areas passing through the two groups of pressure rollers 1 54 in different areas. The crushed stone passes through the material receiving frame 1 52, passes over the pressure roller 1 54, and slides down to the concave slot through the inclined surface of the material receiving frame 1 52. Then, the ore materials in the two areas that have been initially crushed slide down to the corresponding surface of the material receiving frame 2 53 at the lower end.

[0046] The front end rotating shafts of the two groups of rollers 1 54 and the front end rotating shafts of the two groups of rollers 2 55 are fixedly mounted with transmission wheels 3 58, and a transmission belt is sleeved between the two corresponding groups of transmission wheels 3 58, and the transmission action of the transmission wheels 3 58 and the transmission belt forces the two groups of rollers 2 55 to rotate in coordination, and further crush the two volumes of ores that have been crushed initially, and the fully crushed ore particles slide down the inclined surface of the receiving frame 2 53 and are discharged;

[0047] On the basis of ore material screening, multi-stage crushing is carried out in different zones and layers, which is conducive to achieving full crushing of the ore;

[0048] It is worth noting that, due to the large volume of the coarse ore, after multiple layers of rolling, the volume of the ore rolled in the right rolling area is large, and it is very easy for broken stones to get stuck in the gap between the pressure roller 1 54 and the material receiving frame 1 52, and between the pressure roller 2 55 and the material receiving frame 2 53, which can easily cause the pressure roller assembly to stop and the ore material to be blocked;

[0049] See also Figure 2 and Figure 6As shown, a deflection gear 59 is fixedly installed at the hinge rod near the front end of the material receiving frame 1 52 and the two sets of material receiving frames 2 53, and a driving gear 510 is meshed and connected between the upper and lower sets of deflection gears 59, and a motor 2 511 is commonly arranged between the rear end shaft of the driving gear 510 and the front end of the vertical plate 51;

[0050] Therefore, after intermittent material pressing, the starting motor 2 511 drives the driving gear 510 to rotate counterclockwise, and the upper and lower sets of deflection gears 59 are respectively meshed with the driving gear 510, and the two sets of deflection gears 59 rotate clockwise to respectively drive the upper and lower material receiving frames 1 52 and 2 53 on the right side to deflect downward, so that the distance between the material receiving frame 2 53 and the material receiving frame 1 52 and the pressure roller 2 55 and the material receiving frame 2 53 is increased, so as to assist the discharge of the gravel particles that are stuck as soon as possible, reduce the situation of material jamming and movement stagnation, and improve the efficient crushing efficiency of ore.

[0051] When the present invention is in use, ores of different volumes are collected and poured into the material dividing circular frame 2 through the feed trough. The ores are first accumulated inside the material dividing circular frame 2 and located on one side of the resisting bar 202 (on the same side of the arc-shaped material dividing). Then, the double-axis motor 201 is started to drive the resisting bar 202 to rotate counterclockwise first, and the resisting bar 202 pushes several groups of ores to slide along the left inner wall of the material dividing circular frame 2.

[0052] Among them, finely crushed ore particles and crushed stone particles with a volume smaller than the slot of the arc-shaped dividing trough 1 are discharged outward through the arc-shaped dividing trough 1 and slide down to the inclined surface on one side of the guide platform 3, until the bar 202 rotates to approach the feed trough, and then the double-axis motor 201 is used to drive the bar 202 to rotate in the opposite direction, and the remaining unscreened coarse ore blocks are pushed to the arc-shaped dividing trough 2 on the inner wall of the other side of the dividing circular frame 2, and the remaining ore blocks are forced to be discharged outward through the arc-shaped dividing trough 2 and slide down to the inclined surface on the other side of the guide platform 3. The ores of the two flow directions are divided along the inclined surface of the guide platform 3 and wait to slide down to the corresponding advanced crushing mechanism 5 for zone crushing processing;

[0053] After the ore materials that have been preliminarily screened slide to the corresponding inclined surfaces of the receiving frame 52, the motor 57 is started to first drive one of the transmission wheels 56 to rotate, and the other transmission wheel 56 is forced to rotate under the action of the transmission belt. At the same time, the pressure roller 54 connected to the transmission wheel 56 also rotates, and the crushed stone areas passing through the two groups of pressure rollers 54 are crushed in different areas. The crushed stone passes through the receiving frame 52, passes over the pressure roller 54, and slides down through the inclined surface of the receiving frame 52 to the concave slot;

[0054] Then, the ore materials in the two areas of the initial rolling slide down to the corresponding surface of the second material receiving frame 53 at the lower end, and the transmission wheel 3 58 and the transmission belt force the two sets of rollers 55 to rotate in coordination, and further roll the two volumes of ore that have been initially rolled, and the fully rolled ore particles slide down through the inclined surface of the second material receiving frame 53 and are discharged;

[0055] At the same time, the starting motor 2 511 drives the driving gear 510 to rotate counterclockwise, and the upper and lower sets of deflection gears 59 are respectively meshed with the driving gear 510, and the two sets of deflection gears 59 are forced to rotate clockwise to drive the upper and lower material receiving frames 1 52 and 2 53 on the right side to deflect downward respectively, forcing the distance between the material receiving frame 2 53 and the material receiving frame 1 52 and the pressure roller 2 55 and the material receiving frame 2 53 to increase, so as to assist the discharge of the stuck gravel particles as soon as possible.
