Description

Technical Field

[0001] The invention relates to the technical field of prospecting engineering equipment, in particular to mining ore sample crushing equipment suitable for prospecting engineering. Background Art

[0002] In the exploration and development of mineral resources, accurate understanding of the properties, composition, reserves and other information of the ore is of vital importance for subsequent mine planning, mineral processing process design and resource evaluation.

The jaw crusher body is used to crush the mineral sample, and the crushed mineral can slide along the feed plate to the collection frame. The collection frame can receive the mineral that has been crushed by the jaw crusher body, and then the collection frame rises, so that the screening plate can automatically screen out the mineral that is not qualified for crushing, and then the collection frame can automatically pour the mineral that is not qualified for crushing into the jaw crusher body for re-crushing by rotating, and no manual operation is required during the process, which can improve the crushing efficiency of the mineral.

[0004] Based on the above patent, although the equipment can re-crush unqualified ore, there are still the following problems: the crushing device in the comparative document does not have a structure for placing ore samples. For some heavier ore samples, it is time-consuming and laborious to place them into the relatively high feed port of the crushing equipment. The traditional placement structure usually uses a belt conveyor, which not only occupies a large area, but also the ore is easy to roll off the belt during the transportation process from low to high.

[0005] Therefore, we proposed a mining ore sample crushing equipment suitable for prospecting projects in order to solve the above problems. Summary of the invention

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The lifting assembly drives the hopper to rise and fall, and the guide shaft rod and the guide groove cooperate to enable the hopper to flexibly change its opening direction during the rising process. When the hopper opens upward, it can effectively prevent the ore from falling during the rising process, greatly reducing the safety risks that may be caused by the falling of ore, ensuring the safety of operators and the surrounding environment, and providing reliable safety guarantees for the entire ore sample delivery operation. When the hopper opens toward the feed port of the jaw crusher, the ore sample can smoothly roll into the feed port without excessive manual intervention and adjustment, effectively improving the work efficiency of the ore sample crushing link in the prospecting project.

[0026] 2. The roller in the clutch assembly contacts and squeezes the trapezoidal block, so that the L-shaped limit rod is separated from the limit hole on the rectangular block, thereby unlocking the receiving assembly and cooperating with the guide column to move in the middle inclined section of the guide chute to push the receiving assembly closer to or away from the hopper. When the clutch assembly is descending, the roller no longer squeezes the trapezoidal block. Under the action of the spring, the L-shaped limit rod is inserted into the limit hole again, thereby locking the receiving assembly. When the equipment is not in working state or the receiving assembly does not need to move, the movement of the inclined frame can be restricted, thereby fixing the position of the receiving plate to prevent it from sliding due to accidental collision or vibration, thereby ensuring the safety and stability of the equipment.

[0027] 3. When the hopper is turned over to feed the material into the jaw crusher, a gap will be created between the hopper and the feed port due to the turning of the hopper. After the receiving assembly is unlocked by the clutch assembly, it slides in the guide chute in cooperation with the guide column, so that the receiving plate moves to the bottom of the hopper to fill the gap. This effectively prevents the ore sample from spilling from the gap, ensuring that the ore sample can fall completely into the feed port of the jaw crusher, thereby improving the success rate and integrity of the ore sample delivery.

DETAILED DESCRIPTION

[0039] 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 implementation regulations described 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.

[0040] See also Figure 1-9 The present invention provides a technical solution: a mining ore sample crushing device suitable for prospecting engineering, comprising a jaw crusher 1, a base 2 is arranged upstream of the jaw crusher 1, side frames 21 are fixedly installed on both sides of the base 2, a straight slot 211 and a guide slot 212 are opened through the surface of the side frame 21, and the straight slot 211 is close to the jaw crusher 1, and the guide slot 212 is far away from the jaw crusher 1, and the guide slot 212 is divided into three sections, the first section is a small arc section close to the bottom, the second section is a vertical section in the middle, and the third section is a large arc section close to the top, and the radius of the small arc section is equal to that of the large arc section, and at the same time, the endpoints of the small arc section and the large arc section are both facing the direction of the jaw crusher 1, and a delivery mechanism is arranged between the two side frames 21, and the delivery mechanism includes:

[0041] The lifting assembly 3 is installed on the side frame 21. The lifting assembly 3 includes a hopper 36 capable of lifting movement. The hopper 36 is used to put ore samples. A guide shaft 37 and a fixed shaft 38 are fixedly installed on the outer surfaces of both sides of the hopper 36. The guide shaft 37 can move along the inner wall of the guide groove 212, and the fixed shaft 38 can slide up and down along the inner wall of the straight groove 211. When the guide shaft 37 is driven to move inside the small arc segment or the large arc segment in the guide groove 212 through the lifting movement of the hopper 36, the guide shaft 37 can rotate around the axis of the fixed shaft 38, thereby changing the angle of the hopper 36 and realizing the flipping movement of the hopper 36;

[0042] The clutch assembly 4 is provided in two pieces and is symmetrically mounted on the lifting assembly 3, and the clutch assembly 4 can be driven to move up and down by the lifting assembly 3;

[0043] The receiving assembly 5 is arranged between the jaw crusher 1 and the lifting assembly 3, and the receiving assembly 5 is higher than the feed port of the jaw crusher 1. The receiving assembly 5 can slide through the clutch assembly 4 to move away from or close to the hopper 36;

[0044] There are two locking assemblies 6 , which are respectively installed on the surfaces of the two side frames 21 on the opposite sides, and are used to limit the receiving assembly 5 .

[0045] Specifically, the hopper 36 is in a V-shaped structure with only one opening, and the rest of the parts are closed structures. The hopper 36 is initially in a low position, which is convenient for the staff to load the ore sample. The operation of the lifting assembly 3 can drive the hopper 36 to rise and fall, and the guide shaft 37 moves along the guide groove 212. When passing through the small arc segment, the hopper 36 can rotate around the fixed shaft 38, so that the opening of the hopper 36 can be converted to the side or upward opening. When the opening of the hopper 36 is upward, it can effectively prevent the ore from falling during the rising process. The guide shaft 37 moves along the guide groove 212 and passes through the middle vertical section, so that the upward opening of the hopper 36 is continuously maintained. When the guide shaft 37 moves along the guide groove 212 and passes through the large arc section, the opening of the hopper 36 can be turned upward or toward the feed port of the jaw crusher 1. When the opening of the hopper 36 is toward the feed port of the jaw crusher 1, the ore sample will roll into the feed port of the jaw crusher 1, thereby completing the operation of placing the ore sample.

[0046] In this embodiment, if Figure 6 As shown, a crossbeam 22 is fixedly installed between the opposite side surfaces of the two side frames 21 , and an axle frame 23 is fixedly installed at a position between the opposite side surfaces of the two side frames 21 and away from the crossbeam 22 .

[0047] Specifically, the shaft frame 23 provides a rotation support point for the worm 310 , so that the worm 310 can stably mesh with the worm wheel 311 for transmission, thereby ensuring smooth power transmission of the lifting assembly 3 .

[0048] In this embodiment, if Figure 6 As shown, a support plate 24 is fixedly mounted on the surface of each of the two side frames 21 facing the jaw crusher 1 , and a horizontally arranged slide groove 241 is formed through the surface of the support plate 24 .

[0049] Specifically, the support plate 24 provides a support base for the installation and sliding of the receiving assembly 5. The chute 241 serves as a sliding track for the slider 52 of the receiving assembly 5, and defines the horizontal movement direction of the receiving assembly 5, so that it can accurately approach or move away from the hopper 36 under the action of the clutch assembly 4.

[0050] In this embodiment, if Figure 7 As shown, the lifting assembly 3 also includes:

[0051] Rotating shafts 31, the number of rotating shafts 31 is set to two, and they are distributed between the two side frames 21 in an up-and-down position relationship. Both ends of the rotating shaft 31 are movable through the surface of the side frame 21 and extend to the other side. Sprocket wheels 32 are fixedly installed at both ends of the rotating shaft 31, and a chain 33 is arranged between the surfaces of the two sprocket wheels 32 distributed up and down. A connecting plate 34 is installed on the chain 33, and a lifting plate 35 rotatably connected to a fixed shaft rod 38 is installed on the connecting plate 34;

[0052] The motor 39 is fixedly mounted on the top of the crossbeam 22, and a worm 310 is mounted on the output end of the motor 39, and one end of the worm 310 is rotatably mounted on the shaft frame 23;

[0053] The worm wheel 311 is fixedly sleeved on the outer wall of the upper rotating shaft 31 , and the worm wheel 311 is meshedly connected with the worm 310 .

[0054] Specifically, the motor 39 is started, and the worm 310 at the output end rotates. Due to the meshing transmission between the worm 310 and the worm wheel 311, the upper rotating shaft 31 is driven to rotate. The sprockets 32 at both ends of the upper rotating shaft 31 rotate and the lower sprocket 32 ​​rotates synchronously through the chain 33. The connecting plate 34 on the chain 33 drives the lifting plate 35 to rise or fall, and the lifting plate 35 drives the hopper 36 to realize the lifting movement through the hopper 36 connected to the fixed shaft 38.

[0055] In this embodiment, if Figure 1-9As shown, the clutch assembly 4 includes an L-shaped fixed plate 41 fixedly mounted on the surface of the lifting plate 35, a guide column 42 is installed on the inner wall of the L-shaped fixed plate 41 facing the side frame 21, a roller seat 43 is installed on the surface of the L-shaped fixed plate 41 away from the outer frame 21, a roller shaft 44 is rotatably arranged inside the roller seat 43, and the axis of the roller shaft 44 is horizontally arranged, and the receiving assembly 5 includes a receiving plate 51, the width of the receiving plate 51 is less than the distance between the two side frames 21, and the receiving plate 51 is inclined downward in the direction of the jaw crusher 1, and sliders 52 are fixedly mounted on the surfaces of both sides of the receiving plate 51, and the sliders 52 can slide along the inside of the slide groove 241. A connecting rod 53 is fixedly installed on the outer surface of the slider 52, and the connecting rod 53 extends in the direction of the lifting assembly 3. An inclined frame 54 is fixedly connected to the side surface of the connecting rod 53 facing the lifting assembly 3. A guiding inclined groove 541 capable of accommodating the guide column 42 is provided on the side surface of the inclined frame 54 away from the receiving plate 51. The guiding inclined groove 541 is divided into three sections. The first section is a bottom vertical section away from the jaw crusher 1 and facing downward, the second section is a top vertical section close to the jaw crusher 1 and facing upward, and the distance between the first section and the second section of the vertical line is the same as the length of the slide 241. The third section is an intermediate inclined section connecting the first section and the second section. A support rod 55 is fixedly installed at a position near the jaw crusher 1, a wheel frame 56 is symmetrically installed at the bottom of the support rod 55, and a support wheel 57 is symmetrically installed at the bottom of the wheel frame 56. The locking assembly 6 includes a rectangular block 61, which is installed on the side surface of the inclined frame 54 facing the jaw crusher 1. A limited position hole 611 is penetrated through the rectangular block 61. The locking assembly 6 also includes a U-shaped mounting frame 62, which is installed on the side surface of the side frame 21 away from the receiving plate 51. A square column 63 is slidably penetrated on the side surface of the U-shaped mounting frame 62 away from the side frame 21, and a limited position hole 611 is fixedly connected to the square column 63 on the side surface away from the side frame 21. A trapezoidal block 65 is fixedly connected to a positioning plate 64 and a surface of a square column 63 on one side facing the side frame 21. The trapezoidal block 65 can contact the surface of the roller shaft 44, and the roller shaft 44 in the clutch assembly 4 contacts the trapezoidal block 65, which can squeeze the trapezoidal block 65 to move away from the side frame 21. A spring 66 that generates a thrust for the trapezoidal block 65 is installed on the inner wall of one side of the U-shaped mounting frame 62. An L-shaped limiting rod 67 that can be inserted into the limiting hole 611 is fixedly connected to the surface of the trapezoidal block 65 on one side facing the jaw crusher 1. When the trapezoidal block 65 moves in the direction away from the side frame 21, the L-shaped limiting rod 67 can be separated from the inside of the limiting hole 611.

[0056] Specifically, the L-shaped fixing plate 41 serves as the basic mounting component of the clutch assembly 4, which stably fixes the guide column 42 and the roller seat 43 on the lifting plate 35, so that they can move up and down together with the lifting plate 35. During the operation of the equipment, when the guide column 42 rises and enters the bottom vertical section of the guide inclined groove 541, the roller shaft 44 contacts the trapezoidal block 65 and squeezes the L-shaped limiting plug 67 on the trapezoidal block 65, so that the L-shaped limiting plug 67 is separated from the limiting hole 611 on the rectangular block 61, thereby unlocking the receiving assembly 5. When the guide column 42 moves in the middle inclined section, it pushes the receiving assembly 5 close to the hopper 36. The rotation design of the roller shaft 44 reduces the friction resistance when contacting the trapezoidal block 65, making the clutch action smoother, reducing the wear of the components, and improving the service life and operation reliability of the equipment. Similarly, when the guide column 42 descends and passes When in the middle tilting section, the receiving assembly 5 will move away from the hopper 36, that is, it will reset until it drops to the bottom vertical section. The roller 44 will first squeeze the trapezoidal block 65 to lift the L-shaped limit rod 67 to prevent the inclined frame 54 from interfering with the L-shaped limit rod 67 during the reset process, until the guide column 42 is completely moved out of the guide inclined groove 541. At this time, the roller 44 no longer squeezes the trapezoidal block 65, and under the action of the spring 66, the trapezoidal block 65 is pushed to move, so that the L-shaped limit rod 67 is inserted into the limit hole 611 again, thereby locking the receiving assembly 5. When the equipment is not in working state or the receiving assembly 5 does not need to move, the L-shaped limit rod 67 is inserted into the limit hole 611 to limit the movement of the inclined frame 54, thereby fixing the position of the receiving plate 51 to prevent it from sliding due to accidental collision or vibration, thereby ensuring the safety and stability of the equipment.

[0057] In this embodiment, if Figure 1 and Figure 2 As shown, bearing plates 11 are installed on both sides of the jaw crusher 1, and the top surface of the bearing plate 11 is in contact with the supporting wheel 57. A baffle 12 for blocking the ore sample is installed on the surface of the jaw crusher 1 located at the feed port.

[0058] Specifically, when the receiving tray 51 moves, the supporting wheel 57 rolls on the load-bearing plate 11 and can bear part of the weight of the receiving tray 51 and the ore sample, disperse the force on the equipment, and protect the equipment structure. In the process of the ore sample on the receiving tray 51 rolling into the feed port of the jaw crusher 1, the baffle 12 can effectively prevent the ore sample from accidentally overflowing the feed port, ensuring that the ore sample can accurately enter the jaw crusher 1 for crushing, thereby improving the accuracy of ore sample delivery and the working reliability of the equipment.

[0059] The working principle of the device is as follows: the initial position of the hopper 36 is at the lower limit position. When the hopper 36 is at the low position, it is convenient to put the ore sample to be crushed into the hopper 36. After the ore sample to be crushed is placed in the hopper 36, the motor 39 is started to drive the worm 310 to rotate, and the meshing connection between the worm 310 and the worm wheel 311 drives the upper rotating shaft 31 to rotate, so that the sprocket wheels 32 at both ends of the rotating shaft 31 rotate accordingly, and the chain 33 drives the lower sprocket wheel 32 to rotate synchronously, and the connecting plate 34 on the chain 33 drives the lifting plate 35 to move up and down, and the lifting plate 35 The fixed shaft rod 38 on the hopper 36 slides up and down along the inner wall of the straight slot 211, driving the hopper 36 to rise. At the same time, the guide shaft rods 37 on both sides of the hopper 36 move along the inner wall of the guide groove 212. When the guide shaft rod 37 moves in the small arc segment in the guide groove 212, due to the positional relationship between the guide shaft rod 37 and the fixed shaft rod 38, the guide shaft rod 37 can rotate around the axis of the fixed shaft rod 38 until the guide shaft rod 37 completely enters the vertical section of the guide groove 212. At this time, the angle of the hopper 36 changes, and the opening of the hopper 36 changes from the initial posture facing sideways to the upward posture (such as Figure 3 As shown in the figure), the ore can be effectively prevented from falling during the ascent, greatly reducing potential safety hazards.

[0060] In order to prevent the hopper 36 with its opening facing upward from interfering with the receiving plate 51 during the rising process, the initial position of the receiving assembly 5 is at a limit position away from the hopper 36 .

[0061] As the lifting assembly 3 moves upward, the clutch assembly 4 installed on the surface of the lifting plate 35 rises accordingly. When the guide column 42 in the clutch assembly 4 enters the bottom vertical section of the guide inclined groove 541 during the upward process, the roller shaft 44 will also contact the trapezoidal block 65. When the roller shaft 44 squeezes the trapezoidal block 65, the trapezoidal block 65 overcomes the thrust of the spring 66 and moves away from the side frame 21. The L-shaped limiting rod 67 on the trapezoidal block 65 is separated from the limiting hole 611 on the rectangular block 61. At this time, the receiving assembly 5 is unlocked.

[0062] When the receiving assembly 5 is unlocked, the guide column 42 enters the middle inclined section of the guiding inclined groove 541 and moves inside, cooperating with the inclined frame 54, the connecting rod 53 and the slider 52 to slide the receiving plate 51 and bring it closer to the hopper 36, and the hopper 36 has moved to the top of the receiving plate 51.

[0063] As the lifting assembly 3 continues to move upward until the guide shaft 37 enters the large arc segment in the guide groove 212, the guide shaft 37 rotates around the axis of the fixed shaft 38, so that the hopper 36 continues to flip toward the jaw crusher 1 until the opening of the hopper 36 changes from facing upward to facing the feed port of the jaw crusher 1 (such as Figure 5 At this time, the ore sample in the hopper 36 will roll down to the feed port of the jaw crusher 1, thereby completing the operation of placing the ore sample.

[0064] When the hopper 36 is turned over in the direction of the jaw crusher 1 to feed materials, since the hopper 36 is turned over around the fixed shaft 38, the side of the hopper 36 facing the jaw crusher 1 is also turned over. As the angle continues to change, a gap will be generated between the hopper 36 and the feed port of the jaw crusher 1. At this time, since the receiving plate 51 is located under the hopper 36, the gap can be filled, thereby preventing the gap caused by the angle change of the hopper 36 from causing the ore sample to be spilled.
