Description

Technical Field

[0001] The present invention relates to the technical field of prospecting engineering equipment, and specifically to a crushing device for ore samples adapted to prospecting engineering for mining. Background Art

[0002] In the exploration and development of mineral resources, accurately understanding information such as the properties, components, and reserves of ores is of crucial significance for subsequent mine planning, beneficiation process design, and resource assessment. As an important means to obtain these key information, the technological development of prospecting engineering has always received much attention.

[0003] In the prior art, as disclosed in the publication number: CN117599888B, a crushing device for ore samples used in prospecting is disclosed. It includes a jaw crusher body, a feeding plate, a discharge frame, a collection frame, a screening plate, a rotating baffle, etc. The screening plate is connected to the side of the collection frame. A rotating baffle is rotatably connected to the side of the collection frame away from the screening plate. The upper end of the rotating baffle is aligned with the end of the feeding plate. The jaw crusher body is used to crush ore samples, and the crushed ore can slide down along the feeding plate into the collection frame. The collection frame can receive the ore crushed by the jaw crusher body. Then, by raising the collection frame, the screening plate can automatically screen out the unqualified crushed ore. Then, the rotation of the collection frame can automatically pour the unqualified crushed ore into the jaw crusher body for re-crushing, without manual operation during this period, which can improve the crushing efficiency of the ore.

[0004] Based on the above patent, although the device can re-crush the unqualified crushed ore, there are still the following problems: The crushing device in the comparative document does not have a structure for feeding ore samples. For some relatively heavy ore samples, when they are fed into the relatively high feeding port of the crushing device, it is time-consuming and laborious. And for the traditional feeding structure, a belt conveyor is usually used, which not only occupies a large area, but also the ore is likely to roll off the belt during the process of being conveyed from low to high.

[0005] Therefore, we propose a crushing device for ore samples adapted to prospecting engineering for mining to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a crushing device for ore samples adapted to prospecting engineering for mining to solve the problem in the above background art that there is no structure for feeding ore samples, and it is time-consuming and laborious when some relatively heavy ore samples are fed into the relatively high feeding port of the crushing device.

[0007] To achieve the above object, the present invention provides the following technical solutions: A crushing device for ore samples adapted to prospecting engineering, including a jaw crusher. A base is provided upstream of the jaw crusher. Side frames are fixedly installed on both side surfaces of the base. Straight slots and guiding slots are formed through the surfaces of the side frames. The straight slots are close to the jaw crusher, while the guiding slots are far from the jaw crusher. The guiding slots are divided into three sections. The first section is a small arc section near the bottom, the second section is a vertical section in the middle, and the third section is a large arc section near the top. The radii of the small arc section and the large arc section are equal. At the same time, the endpoints of the small arc section and the large arc section both face the direction of the jaw crusher. A feeding mechanism is provided between the two side frames, and the feeding mechanism includes:

[0008] A lifting component installed on the side frame. The lifting component includes a hopper capable of lifting movement. The hopper is used for feeding ore samples. Guide shafts and fixed shafts are fixedly installed on both outer surfaces of the hopper. The guide shafts can move along the inner wall of the guiding slot, and the fixed shafts can slide up and down along the inner wall of the straight slot. When the hopper moves up and down, driving the guide shafts to move inside the small arc section or the large arc section of the guiding slot, the guide shafts can rotate around the axis of the fixed shafts, thereby changing the angle of the hopper and realizing the tipping movement of the hopper;

[0009] Clutch components, with the number set to two, symmetrically installed on the lifting component, and the lifting component can drive the clutch components to move up and down;

[0010] A receiving component is arranged between the jaw crusher and the lifting component, and the receiving component is higher than the feeding port of the jaw crusher. The clutch components can make the receiving component slide, so that it moves away from or close to the hopper;

[0011] Locking components, with the number set to two, respectively installed on the surfaces of the two opposite sides of the two side frames, for limiting the receiving component.

[0012] Preferably, a cross beam is fixedly installed between the opposite side surfaces of the two side frames, and an axle frame is fixedly installed at a position far from the cross beam between the opposite side surfaces of the two side frames.

[0013] Preferably, support plates are fixedly installed on the surfaces of the two side frames facing the jaw crusher, and horizontal sliding slots are formed through the surfaces of the support plates.

[0014] Preferably, the lifting component further includes:

[0015] Rotating shafts, the number of the rotating shafts is set to two, which are distributed between two side frames in an up-and-down positional relationship. Both ends of the rotating shafts movably penetrate through the surfaces of the side frames and extend to the other side. Sprockets are fixedly installed at both ends of the rotating shafts, and a chain is arranged between the surfaces of the two sprockets distributed up and down. A connecting plate is installed on the chain, and a lifting plate rotatably connected to a fixed shaft rod is installed on the connecting plate.

[0016] A motor, the motor is fixedly installed on the top of the cross beam, and a worm is installed at the output end of the motor. One end of the worm is rotatably arranged on the shaft frame.

[0017] A worm gear, the worm gear is fixedly sleeved on the outer wall of the upper rotating shaft, and the worm gear is meshed with the worm.

[0018] Preferably, the clutch assembly includes an L-shaped fixed plate fixedly installed on the surface of the lifting plate. A guiding column is installed on the inner wall of one side of the L-shaped fixed plate facing the side frame. A roller seat is installed on the surface of the L-shaped fixed plate away from the outer side frame. A roller shaft is rotatably arranged inside the roller seat, and the axis line of the roller shaft is horizontally arranged.

[0019] Preferably, the receiving assembly includes a receiving plate. The width of the receiving plate is smaller than the distance between the two side frames, and the part of the receiving plate facing the jaw crusher is inclined downward. Sliders are fixedly installed on both side surfaces of the receiving plate. The sliders can slide along the inside of the sliding grooves. Connecting rods are fixedly installed on the outer surfaces of the sliders and extend towards the lifting assembly. An inclined frame is fixedly connected to the surface of one side of the connecting rod facing the lifting assembly. A guiding inclined groove capable of accommodating the guiding column is opened on the surface of the inclined frame away from the receiving plate. The guiding inclined groove is divided into three sections. The first section is a bottom vertical section far from the jaw crusher and facing downward. The second section is a top vertical section close to the jaw crusher and facing upward. And the distance between the vertical lines of the first section and the second section is the same as the length of the sliding groove. The third section is an intermediate inclined section connecting the first section and the second section.

[0020] Preferably, a support rod is fixedly installed at a position on the inclined bottom surface of the receiving plate close to the jaw crusher. Wheel frames are symmetrically installed at the bottom of the support rod, and support wheels are symmetrically installed at the bottom of the wheel frames.

[0021] Preferably, the locking assembly includes a rectangular block. The rectangular block is installed on the surface of the inclined frame facing the jaw crusher, and a limiting hole is penetrated through the rectangular block.

[0022] Preferably, the locking assembly further includes a U-shaped mounting bracket which is mounted on the surface of the side frame away from the receiving tray. A square column is slidably penetrated through the surface of the U-shaped mounting bracket away from the side frame. A limiting plate is fixedly connected to the surface of the square column away from the side frame. A trapezoidal block is fixedly connected to the surface of the square column facing the side frame. The trapezoidal block can contact the surface of the roller shaft, and when the roller shaft in the clutch assembly contacts the trapezoidal block, it can squeeze the trapezoidal block to move away from the side frame. A spring for generating a thrust force on the trapezoidal block is mounted on one inner wall of the U-shaped mounting bracket. An L-shaped limiting insertion rod capable of inserting into the limiting hole is fixedly connected to the surface of the trapezoidal block facing the jaw crusher. When the trapezoidal block moves away from the side frame, the L-shaped limiting insertion rod can be separated from the limiting hole.

[0023] Preferably, load-bearing plates are mounted on both side surfaces of the jaw crusher. The top surface of the load-bearing plate contacts the support wheel. A baffle for blocking the ore sample is mounted on the surface of the jaw crusher at the feeding port.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By driving the hopper to lift through the lifting assembly and the cooperation of the guiding shaft rod and the guiding groove, the opening direction of the hopper can be flexibly converted 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 the ore, ensuring the safety of the operators and the surrounding environment, and providing a reliable safety guarantee for the entire ore sample feeding operation. When the hopper opening faces the feeding port of the jaw crusher, the ore sample can smoothly roll into the feeding port without excessive manual intervention and adjustment, effectively improving the working efficiency of the ore sample crushing link in the prospecting project.

[0026] 2. By the contact and extrusion between the roller shaft in the clutch assembly and the trapezoidal block, the L-shaped limiting insertion rod is separated from the limiting hole in the rectangular block, so that the receiving assembly is unlocked. Cooperating with the movement of the guiding column in the middle inclined section of the guiding inclined groove, the receiving assembly is pushed to approach or move away from the hopper. When the clutch assembly descends and the roller shaft no longer squeezes the trapezoidal block, under the action of the spring, the L-shaped limiting insertion rod is inserted into the limiting hole again, thereby locking the receiving assembly. It can limit the movement of the inclined frame when the equipment is in a non-working state or when the movement of the receiving assembly is not required, thus fixing the position of the receiving tray and preventing it from sliding due to accidental collision or vibration, ensuring the safety and stability of the equipment.

[0027] 3. During the process of the hopper tipping and feeding towards the jaw crusher, there will be a gap between the hopper and the feed inlet due to the tipping of the hopper. After the receiving assembly is unlocked under the action of the clutch assembly and slides along the guiding column in the guiding chute, the receiving tray moves under the hopper, thus filling the gap, effectively avoiding the situation where the ore sample spills from the gap. This ensures that the ore sample can completely fall into the feed inlet of the jaw crusher, improving the success rate and integrity of the ore sample feeding. BRIEF DESCRIPTION OF THE DRAWINGS

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 Figures 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 for discharging ore samples. Guide shafts 37 and fixed shafts 38 are fixedly installed on the outer surfaces on both sides of the hopper 36. The guide shafts 37 can move along the inner wall of the guide groove 212, and the fixed shafts 38 can slide up and down along the inner wall of the straight slot 211. When the hopper 36 moves up and down, driving the guide shafts 37 to move inside the small arc segment or the large arc segment in the guide groove 212, the guide shafts 37 can rotate around the axis of the fixed shafts 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 numbers and is symmetrically installed on the lifting assembly 3, and the lifting assembly 3 can drive the clutch assembly 4 to move up and down;

[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 inlet of the jaw crusher 1. The clutch assembly 4 can make the receiving assembly 5 slide, so that it moves away from or close to the hopper 36;

[0044] The locking assembly 6 is provided in two numbers and is respectively installed on the surfaces of the two opposite sides of the two side frames 21 for limiting the receiving assembly 5.

[0045] Specifically, the hopper 36 has a V-shaped structure and has only one opening, and the rest are closed structures. The hopper 36 is initially in a low position, which is convenient for the staff to load the ore samples. Through the operation of the lifting assembly 3, the hopper 36 can be driven to lift. The guide shafts 37 move 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 between the side and the upward opening. When the opening of the hopper 36 is upward, it can effectively prevent the ore from falling during the rising process, improving the operation safety. When the guide shafts 37 move along the guide groove 212 and pass through the middle vertical section, the upward opening of the hopper 36 will be continuously maintained. When the guide shafts 37 move along the guide groove 212 and pass through the large arc segment, the opening of the hopper 36 can be converted between upward and the direction towards the feed inlet of the jaw crusher 1. When the opening of the hopper 36 faces the feed inlet of the jaw crusher 1, the ore samples will roll into the feed inlet of the jaw crusher 1, thus completing the discharging operation of the ore samples.

[0046] In this embodiment, as Figure 6 shown, a cross beam 22 is fixedly installed between the opposite side surfaces of the two side frames 21, and a shaft frame 23 is fixedly installed at a position away from the cross beam 22 between the opposite side surfaces of the two side frames 21.

[0047] Specifically, the shaft bracket 23 provides a rotation support point for the worm 310, enabling the worm 310 to stably mesh and drive with the worm wheel 311, ensuring smooth power transmission of the lifting assembly 3.

[0048] In this embodiment, as Figure 6 shown, support plates 24 are fixedly installed on the surfaces of the two side frames 21 facing the jaw crusher 1, and horizontal sliding grooves 241 are formed through the surfaces of the support plates 24.

[0049] Specifically, the support plate 24 provides a support basis for the installation and sliding of the receiving assembly 5. The sliding groove 241 serves as the sliding track for the slider 52 of the receiving assembly 5, defining the horizontal movement direction of the receiving assembly 5, enabling it to accurately approach or move away from the hopper 36 under the action of the clutch assembly 4.

[0050] In this embodiment, as Figure 7 shown, the lifting assembly 3 further includes:

[0051] A rotating shaft 31. The number of the rotating shafts 31 is set to two, which are distributed in a vertical position relationship between the two side frames 21. Both ends of the rotating shaft 31 are movably penetrated through the surfaces of the side frames 21 and extend to the other side. Chain 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 chain wheels 32 distributed vertically. A connecting plate 34 is installed on the chain 33, and a lifting plate 35 rotatably connected to the fixed shaft rod 38 is installed on the connecting plate 34;

[0052] A motor 39, which is fixedly installed on the top of the cross beam 22. A worm 310 is installed at the output end of the motor 39, and one end of the worm 310 is rotatably arranged on the shaft bracket 23;

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

[0054] Specifically, when the motor 39 is started, the worm 310 at the output end rotates. Due to the meshing drive between the worm 310 and the worm wheel 311, the upper rotating shaft 31 is driven to rotate. The chain wheels 32 at both ends of the upper rotating shaft 31 rotate and drive the lower chain wheel 32 to rotate 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 through the hopper 36 connected to the fixed shaft rod 38, thereby driving the hopper 36 to achieve a lifting motion.

[0055] In this embodiment, as Figures 1-9As shown in the figure, the clutch assembly 4 includes an L-shaped fixed plate 41 fixedly installed on the surface of the lifting plate 35. A guiding column 42 is installed on the inner wall of one side 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 side frame 21. A roller shaft 44 is rotatably provided inside the roller seat 43. The axis line of the roller shaft 44 is horizontally arranged. The receiving assembly 5 includes a receiving plate 51. The width of the receiving plate 51 is smaller than the distance between the two side frames 21, and the part of the receiving plate 51 facing the jaw crusher 1 is inclined downward. Sliders 52 are fixedly installed on both surfaces of the receiving plate 51. The sliders 52 can slide inside the chute 241. A connecting rod 53 is fixedly installed on the outer surface of the slider 52, and the connecting rod 53 extends towards the lifting assembly 3. An inclined frame 54 is fixedly connected to one side surface of the connecting rod 53 facing the lifting assembly 3. A guiding inclined groove 541 capable of accommodating the guiding column 42 is opened on the 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 the bottom vertical section away from the jaw crusher 1 and downward. The second section is the top vertical section close to the jaw crusher 1 and upward. And the distance between the vertical lines of the first section and the second section is the same as the length of the chute 241. The third section is the middle inclined section connecting the first section and the second section. A support rod 55 is fixedly installed at the position of the inclined bottom surface of the receiving plate 51 close to the jaw crusher 1. Wheel frames 56 are symmetrically installed at the bottom of the support rod 55. Support wheels 57 are symmetrically installed at the bottom of the wheel frames 56. The locking assembly 6 includes a rectangular block 61. The rectangular block 61 is installed on the surface of the inclined frame 54 facing the jaw crusher 1. A limiting hole 611 is penetrated through the rectangular block 61. The locking assembly 6 further includes a U-shaped mounting frame 62. The U-shaped mounting frame 62 is installed on the surface of the side frame 21 away from the receiving plate 51. A square column 63 is slidably penetrated through the surface of the U-shaped mounting frame 62 away from the side frame 21. A limiting plate 64 is fixedly connected to the surface of the square column 63 away from the side frame 21. A trapezoidal block 65 is fixedly connected to the surface of the square column 63 facing the side frame 21. The trapezoidal block 65 can contact the surface of the roller shaft 44. And when the roller shaft 44 in the clutch assembly 4 contacts the trapezoidal block 65, it can squeeze the trapezoidal block 65 to move in the direction away from the side frame 21. A spring 66 that generates a thrust on the trapezoidal block 65 is installed on the inner wall of one side of the U-shaped mounting frame 62. An L-shaped limiting insertion rod 67 capable of inserting into the limiting hole 611 is fixedly connected to the surface of the trapezoidal block 65 facing the jaw crusher 1. When the trapezoidal block 65 moves in the direction away from the side frame 21, the L-shaped limiting insertion rod 67 can be separated from 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] Working principle of this device: The initial position of the hopper 36 is at the lower limit position. When the hopper 36 is in 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, by starting the motor 39, the worm 310 is driven to rotate. With the meshing connection between the worm 310 and the worm wheel 311, the upper rotating shaft 31 is driven to rotate, so that the sprockets 32 at both ends of the rotating shaft 31 rotate accordingly. The sprockets 32 below are driven to rotate synchronously through the chain 33, and the connecting plate 34 on the chain 33 drives the lifting plate 35 to move up and down. The fixed shaft rod 38 on the lifting plate 35 slides up and down along the inner wall of the straight groove 211, driving the hopper 36 to rise. At the same time, the guiding shaft rods 37 on both sides of the hopper 36 move along the inner wall of the guiding groove 212. When the guiding shaft rods 37 move in the small arc segment of the guiding groove 212, due to the positional relationship between the guiding shaft rods 37 and the fixed shaft rod 38, the guiding shaft rods 37 can rotate around the axis of the fixed shaft rod 38 until the guiding shaft rods 37 completely enter the vertical segment of the guiding 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 the side to the posture facing upward (as Figure 3 shown), thus effectively avoiding the situation of ore falling during the rising process and greatly reducing the safety hazard.

[0060] In order to avoid interference between the hopper 36 with the opening facing upward and the receiving plate 51 during the rising process, the initial position of the receiving assembly 5 is at the limit position far 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 also moves upward. When the guiding column 42 in the clutch assembly 4 enters the bottom vertical segment of the guiding inclined groove 541 during the upward movement, the roller shaft 44 also contacts the trapezoidal block 65. When the roller shaft 44 presses the trapezoidal block 65, the trapezoidal block 65 moves away from the side frame 21 against the thrust of the spring 66, and the L-shaped limiting insertion rod 67 on the trapezoidal block 65 separates from the limiting hole 611 in the rectangular block 61. At this time, the receiving assembly 5 is unlocked.

[0062] After the receiving assembly 5 is unlocked, at this time, the guiding column 42 also enters the middle inclined segment of the guiding inclined groove 541 and moves inside. Cooperating with the inclined frame 54, the connecting rod 53 and the slider 52, the receiving plate 51 slides to make it close to the hopper 36, and at this time, the hopper 36 has moved above the receiving plate 51.

[0063] As the lifting assembly 3 continues to move upward, until the guiding shaft rod 37 enters the interior of the large arc segment in the guiding groove 212, the guiding shaft rod 37 rotates around the axis line of the fixed shaft rod 38, so that the hopper 36 continues to turn towards the jaw crusher 1 until the opening of the hopper 36 changes from facing upward to facing the feed inlet of the jaw crusher 1 (as Figure 5 shown). At this time, the ore sample in the hopper 36 will roll into the feed inlet of the jaw crusher 1, thus completing the feeding operation of the ore sample.

[0064] When the hopper 36 is turned towards the jaw crusher 1 for feeding, since the hopper 36 rotates around the fixed shaft rod 38, the side of the hopper 36 facing the jaw crusher 1 also rotates accordingly. As the angle changes continuously, a gap will be generated between the hopper 36 and the feed inlet of the jaw crusher 1. At this time, since the receiving tray 51 is exactly below the hopper 36, this gap can be filled, thereby preventing the ore sample from spilling due to the gap generated by the angle change of the hopper 36.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
