Description

TECHNICAL FIELD

[0001] The present application relates to the field of lifting equipment, in particular to an ore lifting device for lead-zinc mine mining. BACKGROUND

[0002] The ore lifting device is a common lifting device in a mine field, which lifts the mined ore to a high place after crushing by a crusher and then drops and piles in an open field. When transportation is needed, the excavator is used to transport the ore into the hopper of the truck. Such a transportation mode cannot realize quantitative transportation, and the truck needs to be weighed by a scale after loading to know the loading weight, which is very inconvenient. Moreover, such a loading mode is easy to cause overloading of the truck, which has a safety hazard. SUMMARY

[0003] In view of the problems in the prior art, the present application provides an ore lifting device for lead-zinc mine mining, which solves the problem that the existing lifting device cannot realize quantitative transportation, and the loading weight can be known during loading, without the need for weighing by a scale after loading, thereby reducing the risk of overloading of the truck.

[0004] The technical scheme adopted by the present application to solve the technical problems is: an ore lifting device for lead-zinc mine mining, comprising a first support, a second support, a first protective plate symmetrically arranged on the first support, a second protective plate symmetrically arranged on the second support, a conveyor belt arranged on the first support and the second support, a motor arranged on the second support, a crusher arranged on the first support, a limiting mechanism symmetrically arranged on the first support, and a storage mechanism arranged on the conveyor belt; the storage mechanism comprises a transport box arranged on the conveyor belt, a first chute arranged on the transport box, a second chute arranged on the transport box, a clamping assembly symmetrically arranged on the transport box, a pressing assembly arranged on the transport box, and a connecting rod assembly arranged on the transport box. The first support and the second support are used to support the entire device, the conveyor belt is used to transport the storage mechanism, the motor drives the conveyor belt, the crusher crushes large pieces of ore into small pieces, the limiting mechanism is used for the movement of the baffle, the transport box is used for storing ore, the first chute cooperates with the pressing assembly and the connecting rod assembly, the second chute cooperates with the pressing assembly, the pressing assembly is used to control the connecting rod assembly, the clamping assembly is used to further clamp the ore, to avoid rolling of the ore in the transport box during transportation on the conveyor belt, and to avoid dropping of the ore out of the transport box, and the bottom of the transport box is provided with a slope, so that the ore falls into the transport box and automatically slides into the bottom of the slope, and a plurality of transport boxes are arranged on the conveyor belt.

[0005] Specifically, the limiting mechanism includes a support plate on the first bracket, a first guide block on the support plate, a second guide block on the support plate, a first spring telescopic rod on the first bracket, a second spring telescopic rod on the first bracket, a third spring telescopic rod sleeved on the second spring telescopic rod, a limiting head on the third spring telescopic rod, a first slider on the third spring telescopic rod, and a linkage assembly on the first spring telescopic rod. The spring coefficient of the first spring telescopic rod is greater than that of the second spring telescopic rod, and the spring coefficient of the second spring telescopic rod is greater than that of the third spring telescopic rod. The first spring telescopic rod is connected to the linkage assembly, and the second spring telescopic rod can drive the third spring telescopic rod to move. The third spring telescopic rod is sleeved on the second spring telescopic rod and can move perpendicular to the second spring telescopic rod. The limiting head has an inclined surface, the first slider has two inclined surfaces, and the second guide block is offset from the first guide block. Taking the front view as reference, when the linkage component is located to the left of the limiting head, it is pushed to the right by the pressing component on the transport box. The first spring telescopic rod is stretched, and the linkage component contacts the limiting head. Due to the inclined surface on the limiting head, as the linkage component continues to move to the right, the limiting head is squeezed by the linkage component, and the third spring telescopic rod retracts. The first guide block and the first slider restrict the movement of the third spring telescopic rod on the second spring telescopic rod. When the linkage component moves to the right of the limiting head, the third spring telescopic rod returns to its original position. At this time, the limiting head is located to the left of the linkage component. When the pressing component stops pushing the linkage component, the first spring telescopic rod retracts, causing the linkage component to move to the left. The linkage component contacts the limiting head. Since the contact point between the linkage component and the limiting head is a plane, the linkage component will cause the limiting head, the third spring telescopic rod, and the first slider to move to the left along the first guide block. The second spring telescopic rod is compressed and moves to the second guide block. Due to the misalignment of the first and second guide blocks, the first slider has an inclined surface. The first slider moves along the inclined surface of the second guide block, causing the third spring telescopic rod to move on the second spring telescopic rod. The limiting block gradually disengages from the linkage assembly. After the limiting block and the linkage assembly disengage, the first spring telescopic rod continues to drive the linkage assembly to move to the left. The second spring telescopic rod loses the pressure of the linkage assembly and will stretch to the right to reset. During the reset process, the first slider contacts the inclined surface on the first guide block, and the first guide block applies a force to the first slider. The third spring telescopic rod moves on the second spring telescopic rod, and the limiting head returns to the movement path of the linkage assembly. When the second spring telescopic rod resets, the limiting mechanism completes the reset. At this time, the linkage assembly is located to the left of the limiting head.

[0006] Specifically, the linkage assembly includes a linkage plate mounted on the first spring telescopic rod, a first rack mounted on the linkage plate, a first gear mounted on the first bracket, a baffle bracket mounted on the first bracket, a third slide groove mounted on the baffle bracket, a baffle mounted on the baffle bracket and moving along the third slide groove, and a second rack mounted on the baffle. Taking the front view as reference, the linkage plate moves to the right under the push of the pressing assembly, the first rack drives the first gear to rotate, and the first gear engages with the second rack. The rotation of the first gear drives the baffle to move to the left, allowing the ore in the crusher to fall into the transport box. After the pressing assembly disengages from the linkage plate, the first spring telescopic rod drives the linkage plate to move to the left, and the first gear drives the baffle to move to the right. Under the action of the limiting mechanism, the baffle slowly closes.

[0007] Specifically, the first protective plate is provided with a fourth sliding groove and a third straight rack. The fourth sliding groove cooperates with the pressing component, and the third straight rack cooperates with the clamping component to control the clamping of the clamping component.

[0008] Specifically, the second protective plate is provided with a guide block and a fourth straight rack. The guide block cooperates with the pressing component, and the fourth straight rack cooperates with the clamping component to control the relaxation of the clamping component.

[0009] Specifically, the clamping assembly includes a clamping bracket on the transport box, a first screw on the clamping bracket, a second screw on the clamping bracket, a second gear sleeved on the first screw, a third gear sleeved on the second screw, a fourth gear on the clamping bracket that meshes with the second and third gears, a first connecting rod on the first and second screws, a second connecting rod sleeved at one end of the first connecting rod, a third connecting rod sleeved at the other end of the first connecting rod, multiple swing arms sleeved on the second and third connecting rods, multiple fourth connecting rods on the swing arms, multiple clamping heads penetrating the clamping bracket, and springs sleeved on the clamping heads. After the second gear contacts the third spur rack, the second gear rotates, driving the fourth gear to rotate, which in turn drives the third gear to rotate. The second and third gears rotate in the same direction. Taking the front view as reference, the second and third gears drive the first and second screws to move downwards. The first and second screws drive the first connecting rod to move downwards, which in turn drives the second and third connecting rods to move downwards. The swing arm also moves downwards, pressing down on the clamping head. The spring is compressed, clamping the ore in the transport box. Because the ore in the transport box is uneven, the ore at higher positions exerts an upward force on the clamping head. The clamping head exerts an upward force on one end of the swing arm, causing the swing arm to rotate slightly. The clamping head on the other side of the swing arm will then move slightly downwards. The upward force on the swing arm also exerts an upward force on one end of the second or third connecting rod, causing the other end of the second or third connecting rod to move slightly downwards, better fitting and clamping the ore in the transport box. When the third gear contacts the fourth spur rack, the third gear rotates, causing the fourth gear to rotate, which in turn causes the second gear to rotate. At this time, the rotation directions of the third and second gears are opposite to those during clamping. The first and second screws move upward, causing the first connecting rod to move upward. The first connecting rod then causes the second and third connecting rods to move upward, and the swing arm also moves upward. The spring applies an upward force to the clamping head, releasing the clamping of the ore in the transport box.

[0010] Specifically, the pressing assembly includes a base plate disposed within the transport box, second sliders symmetrically disposed on the base plate, a third slider penetrating the base plate and moving along a second slide groove, a first telescopic rod disposed on the base plate, a second telescopic rod disposed on the base plate, a fourth slider disposed within the first slide groove, a fifth slide groove disposed on the fourth slider, and a sixth slide groove disposed on the fourth slider. The second slider can move along the fifth slide groove. When there is no ore in the transport box, the fourth slider is located at the top of the first slide groove, the second slider is located at the bottom of the fifth slide groove, and the third slider is located at the top of the second slide groove. The first telescopic rod is used to block the gaps in the first slide groove to prevent ore from entering the first slide groove, and the second telescopic rod is used to block the gaps in the second slide groove to prevent ore from entering the second slide groove. When there is ore in the transport box, taking the front view as reference, the bottom plate moves downward, the second slider moves downward in the fifth chute, the third slider moves downward along the fourth chute, and after the bottom plate moves downward a certain distance, the second slider contacts the bottom of the fifth chute. The bottom plate continues to move downward, the second slider drives the fourth slider to move downward, and the fourth slider drives the linkage assembly to move.

[0011] Specifically, the linkage assembly includes a first rotating shaft symmetrically arranged on the transport box, a second rotating shaft symmetrically arranged on the transport box, a third rotating shaft symmetrically arranged on the clamping assembly, a fourth rotating shaft symmetrically arranged on the clamping assembly, a fifth connecting rod sleeved on the first and third rotating shafts, a sixth connecting rod sleeved on the second and fourth rotating shafts, a fourth spring telescopic rod fixedly arranged on the fifth connecting rod, and a fifth rotating shaft arranged on the fourth spring telescopic rod. The first and second rotating shafts are lower than the top of the first chute. The fifth rotating shaft contacts the fourth slider and can move along the sixth chute. When there is no ore in the transport box, the fourth slider is at the top of the first chute, and the fifth rotating shaft is at the top of the sixth chute. When there is ore in the transport box, the fourth slider moves downward and applies a force to the fifth rotating shaft. The fifth rotating shaft drives the fourth spring telescopic rod to rotate around the first rotating shaft, which in turn drives the fifth connecting rod to rotate. The fourth spring telescopic rod is compressed, and the rotation of the fifth connecting rod drives the clamping mechanism to move towards the center, which in turn drives the sixth connecting rod to rotate. The sixth connecting rod ensures that the clamping mechanism rotates smoothly. When the fourth slider moves to the bottom of the first chute, the fifth rotating shaft is at the top of the sixth chute. At this time, the fourth spring telescopic rod is in a compressed state, and there is an angle between the two fourth spring telescopic rods. Therefore, the fourth spring telescopic rod will apply a force to the fifth rotating shaft. The downward component of this force causes the fifth rotating shaft to move downward along the sixth chute to the bottom of the sixth chute.

[0012] The beneficial effects of this invention are:

[0013] (1) It can transport in a fixed quantity, and the load weight can be known at the time of loading, which reduces the risk of truck overloading.

[0014] (2) It can protect the conveyor belt and prevent excessive ore accumulation on the conveyor belt from causing damage.

[0015] (3) Further fix the ore to prevent it from tilting, rolling and falling out of the transport container during transportation. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1-15 As shown, the ore hoisting device for lead-zinc mines according to the present invention includes a first support 1, a second support 2, a first protective plate 3 symmetrically arranged on the first support, a second protective plate 4 symmetrically arranged on the second support, a conveyor belt 5 arranged on the first support and the second support, a motor 6 arranged on the second support, a crusher 7 arranged on the first support, a limiting mechanism 8 symmetrically arranged on the first support, and a storage mechanism 9 arranged on the conveyor belt; the storage mechanism includes a transport box 91 arranged on the conveyor belt, a first chute 92 arranged on the transport box, a second chute 93 arranged on the transport box, a clamping assembly 94 symmetrically arranged on the transport box, a pressing assembly 95 arranged on the transport box, and a connecting rod assembly 96 arranged on the transport box.

[0034] Specifically, the limiting mechanism includes a support plate 81 on the first bracket, a first guide block 82 on the support plate, a second guide block 83 on the support plate, a first spring telescopic rod 84 on the first bracket, a second spring telescopic rod 85 on the first bracket, a third spring telescopic rod 86 sleeved on the second spring telescopic rod, a limiting head 87 on the third spring telescopic rod, a first slider 88 on the third spring telescopic rod, and a linkage assembly 89 on the first spring telescopic rod.

[0035] Specifically, the linkage assembly includes a linkage plate 891 mounted on the first spring telescopic rod, a first rack 892 mounted on the linkage plate, a first gear 893 mounted on the first bracket, a baffle bracket 894 mounted on the first bracket, a third slide groove 895 mounted on the baffle bracket, a baffle 896 mounted on the baffle bracket and moving along the third slide groove, and a second rack 897 mounted on the baffle.

[0036] Specifically, the first protective plate is provided with a fourth sliding groove 31 and a third straight toothed rack 32.

[0037] Specifically, the second protective plate is provided with a guide block 41 and a fourth straight rack 42.

[0038] Specifically, the clamping assembly includes a clamping bracket 941 mounted on the transport box, a first screw 942 mounted on the clamping bracket, a second screw 943 mounted on the clamping bracket, a second gear 944 sleeved on the first screw, a third gear 945 sleeved on the second screw, a fourth gear 946 mounted on the clamping bracket and cooperating with the second and third gears, a first connecting rod 947 mounted on the first and second screws, a second connecting rod 948 sleeved on one end of the first connecting rod, a third connecting rod 949 sleeved on the other end of the first connecting rod, multiple swing arms 940 sleeved on the second and third connecting rods, multiple fourth connecting rods 9411 mounted on the swing arms, multiple clamping heads 9412 penetrating the clamping bracket, and springs 9413 sleeved on the clamping heads.

[0039] Specifically, the pressing assembly includes a base plate 951 disposed inside the transport box, a second slider 952 symmetrically disposed on the base plate, a third slider 953 that penetrates the base plate and moves along the second slide groove, a first telescopic rod 954 disposed on the base plate, a second telescopic rod 955 disposed on the base plate, a fourth slider 956 disposed in the first slide groove, a fifth slide groove 957 disposed on the fourth slider, and a sixth slide groove 958 disposed on the fourth slider.

[0040] Specifically, the linkage assembly includes a first rotating shaft 961 symmetrically arranged on the transport box, a second rotating shaft 962 symmetrically arranged on the transport box, a third rotating shaft 963 symmetrically arranged on the clamping assembly, a fourth rotating shaft 964 symmetrically arranged on the clamping assembly, a fifth connecting rod 965 sleeved on the first and third rotating shafts, a sixth connecting rod 966 sleeved on the second and fourth rotating shafts, a fourth spring telescopic rod 967 fixedly arranged on the fifth connecting rod, and a fifth rotating shaft 968 arranged on the fourth spring telescopic rod.

[0041] In operation, the ore is placed into the crusher. At this time, the bottom plate and the third slider are located at the top of the second chute, the fourth slider is located at the top of the first chute, the second slider is located at the top of the fifth chute, and the fifth rotating shaft is located at the top of the sixth chute. The fifth rotating shaft is higher than the first and second rotating shafts. The fourth spring telescopic rod is in a compressed state, and it applies a vertically upward component force to the fifth rotating shaft. The clamping mechanism on the transport box is in an open state, located at the oblique side of the transport box. The transport box is conveyed by the conveyor belt and flipped from bottom to top. The third slider moves along the fourth chute on the first protective plate. After the third slider contacts the linkage plate, it pushes the linkage plate to move to the right. The first spring telescopic rod is stretched, and the linkage plate... The first spur rack drives the first gear to rotate. The first gear engages with the second spur rack. The rotation of the first gear causes the baffle to move to the left on the third chute, allowing the ore in the crusher to fall into the transport box. The linkage plate continues to move to the right and contacts the limit head. Due to the inclined surface on the limit head, the limit head is squeezed by the linkage plate as it continues to move to the right. The first guide block and the first slider restrict the movement of the third spring telescopic rod on the second spring telescopic rod, so the third spring telescopic rod can only retract. When the third slider pushes the linkage plate to the rightmost end of the upper section of the fourth chute, the limit head is located on the left side of the linkage assembly. The third spring telescopic rod resets, the motor stops, the transport box is located below the crusher, and the third slider is located at the top of the vertical section of the fourth chute. After the crusher breaks large pieces of ore into smaller pieces, they fall into the transport box and are lifted by the bottom plate. Because the fifth rotating shaft is higher than the first and second rotating shafts, the fourth spring telescopic rod is in a compressed state. The weight of the ore on the bottom plate needs to continue compressing the fourth spring telescopic rod before the linkage assembly moves, rotating the clamping mechanism towards the center and closing the transport box. Once the base plate has supported a sufficient weight of ore, the second slider drives the fourth slider downwards along the first chute. The fourth slider applies a downward force to the fifth rotating shaft, causing the fifth rotating shaft to rotate the fourth spring telescopic rod around the first rotating shaft, which in turn rotates the fifth connecting rod. The fourth spring telescopic rod continues to be compressed, and the rotation of the fifth connecting rod causes the clamping mechanism to move towards the center. The sixth connecting rod rotates along with the fifth, ensuring the smooth rotation of the clamping mechanism and gradually closing the transport box. When the fifth rotating shaft is collinear with the first and second rotating shafts, the compression of the fourth spring telescopic rod reaches its maximum. When the base plate moves downwards to the bottom of the transport box, the fourth slider is at the bottom of the first chute, the second slider is at the bottom of the fifth chute, and the fifth rotating shaft is at the top of the sixth chute and slightly lower than the first and second rotating shafts. The fourth spring telescopic rod applies a vertically downward component force to the fifth rotating shaft, accelerating its downward movement. When the fifth rotating shaft reaches the bottom of the sixth chute, the transport box is completely closed.

[0042] As the base plate moves downwards, the third slider moves downwards along the vertical section of the fourth slide groove, disengaging from the linkage plate. The first spring telescopic rod retracts, causing the linkage plate to move to the left. The linkage plate then contacts the limit head. Since the contact point between the linkage plate and the limit head is a plane, the linkage assembly will cause the limit head, the third spring telescopic rod, and the first slider to move to the left along the first guide block. The second spring telescopic rod is compressed and moves to the second guide block. Due to the misalignment of the first and second guide blocks, the first slider has an inclined surface. The first slider will move along the inclined surface of the second guide block, causing the third... The spring telescopic rod moves on the second spring telescopic rod, and the limiting block gradually disengages from the linkage plate. After the limiting block and the linkage plate disengage, the first spring telescopic rod continues to drive the linkage plate to move to the left. The second spring telescopic rod, having lost the pressure of the linkage plate, stretches to the right to reset. During the reset process, the first slider contacts the inclined surface on the first guide block, and the first guide block applies a force to the first slider. The third spring telescopic rod moves on the second spring telescopic rod, and the limiting head returns to the movement path of the linkage plate. When the second spring telescopic rod resets, the limiting mechanism completes its reset, and at this time, the linkage plate is located to the left of the limiting head.

[0043] The motor starts, the transport box moves to the right, the third slider moves to the right along the lower section of the fourth slide groove, the second gear contacts the third spur rack, the second gear rotates, driving the fourth gear to rotate, the fourth gear drives the third gear to rotate, the second gear and the third gear rotate in the same direction. Taking the front view as reference, the second gear and the third gear drive the first screw and the second screw to move downward, the first screw and the second screw drive the first connecting rod to move downward, the first connecting rod drives the second connecting rod and the third connecting rod to move downward, the swing arm also moves downward, the swing arm presses down on the clamping head, the spring is compressed, clamping the ore in the transport box. Because the ore in the transport box is uneven, the ore at the higher position will exert an upward force on the clamping head, the clamping head will exert an upward force on one end of the swing arm, the swing arm will rotate slightly, the clamping head on the other side of the swing arm will move slightly downward, the upward force on the swing arm will also exert an upward force on one end of the second or third connecting rod, causing the other end of the second or third connecting rod to move slightly downward, better fitting and clamping the ore in the transport box. When the transport box moves to its highest point, the third gear contacts the fourth spur rack. The third gear rotates, driving the fourth gear to rotate, which in turn drives the second gear to rotate. At this point, the rotation directions of the third and second gears are opposite to those during clamping. The first and second screws move upward, driving the first connecting rod to move upward. The first connecting rod then drives the second and third connecting rods to move upward, and the swing arm also moves upward. The spring applies an upward force to the clamping head, releasing the clamping of the ore inside the transport box. The transport box continues to move to the right, the third slider moves along the guide block, the base plate slowly rises, and the second slider slowly rises in the fifth chute. When it reaches the top of the fifth chute, it will drive... The fourth slider moves upward along the first groove, causing the fifth rotating axis to move upward as well. This fifth rotating axis causes the fourth spring telescopic rod to rotate around the first rotating axis, which in turn causes the fifth connecting rod to rotate. The fourth spring telescopic rod continues to be compressed, and the rotation of the fifth connecting rod causes the clamping mechanism to move to both sides. The sixth connecting rod rotates along with the fourth, ensuring the clamping mechanism rotates smoothly and gradually opens the transport box. After the fifth and sixth connecting rods have rotated past the vertical position, the weight of the clamping mechanism accelerates their rotation. The fifth rotating axis moves to the top of the sixth groove, and the transport box is fully opened, with the clamping mechanism positioned at an angle to the side of the transport box. The transport box flips downward with the conveyor belt, and the ore inside is poured into the truck's cargo bed. When the transport box flips downward, the fourth spring telescopic rod remains compressed to prevent the clamping mechanism from rotating due to its own weight.

[0044] The aforementioned motor, crusher, and conveyor belt were all purchased from the market.
