[0003] Generally, mined ore is crushed by a crusher. In the current crushing work, large-volume ore needs to be screened out first, and then crushed by a larger crusher. Then, the crushed small-volume ore is transported to a small crusher through transmission equipment for further crushing, which is convenient for transportation.

[0004] In the existing technology, large volumes of ore need to be screened and then transported after crushing. The entire process involves many steps, which seriously affects the overall production efficiency. Utility Model Content

[0006] The technical solution of the utility model is:

[0007] A high-efficiency crusher, comprising:

[0008] The shell has a feed port at the top and a discharge port at the bottom. The upper half is the primary crushing area, and the lower half is the secondary crushing area.

[0009] Two pressing plates are movably arranged on both sides of the primary crushing area and can move closer to or further away from each other;

[0010] Multiple hydraulic cylinders are respectively arranged on the sides of the two pressure plates that are away from each other, and the piston rods of the hydraulic cylinders are connected to the pressure plates;

[0011] A plurality of cones are distributed on the two pressing plates and located on the side where the two pressing plates are close to each other;

[0016] A plurality of cross bars are arranged in parallel in the shell body and are located on the same plane, and are all located between the primary crushing zone and the secondary crushing zone.

[0017] Optionally, the pressing plate includes two plates, which are arranged one above the other and one below the other to form a V-shaped structure, and the angle between the two plates is greater than 90°;

[0018] The two plates are arranged opposite to each other at sides where the included angle is less than 180°, and all cones are arranged on this side of the pressing plate.

[0019] Optionally, the pressure plate further includes a baffle, which is arranged on the top of the two plates and forms a Z-shaped structure with the two plates.

[0020] Optionally, windows are provided on both sides of the primary crushing zone of the shell, and the hydraulic cylinder penetrates into the interior of the primary crushing zone through the windows and is connected to the pressing plate.

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] Example:

[0042] See also Figure 1 、 Figure 2 and Figure 3 This embodiment discloses a high-efficiency crusher, comprising a housing 10, a pressure plate 21, a hydraulic cylinder 22, a cone 23, a motor 31, a main shaft 32, and a hammer 33. The pressure plate 21 is mounted on the piston rod of the hydraulic cylinder 22 and is located in the upper half of the housing 10. The cone 23 is entirely mounted on the pressure plate 21. The hydraulic cylinder 22 drives the pressure plate 21 to move within the housing 10, thereby causing the cone 23 to squeeze the ore within the housing 10, thereby crushing the ore.

[0043] The motor 31 is mounted on the housing 10. The spindle 32 is coaxial with the output shaft of the motor 31 and is located in the lower half of the housing 10. All hammers 33 are mounted on the spindle 32. Ore crushed in the upper half of the housing 10 falls into the lower half of the housing 10. The motor 31 drives the spindle 32 to rotate, and the spindle 32 swings the hammers 33 to crush the ore again.

[0044] Specifically, the top of the housing 10 is the feed port 11, the bottom is the discharge port 12, the upper half of the housing 10 is the primary crushing zone 13, and the lower half is the secondary crushing zone 14. There are two pressing plates 21, one on each side of the primary crushing zone 13. At the same time, multiple hydraulic cylinders 22 are respectively provided on both sides of the primary crushing zone 13. The piston rods of the hydraulic cylinders 22 are connected to the corresponding pressing plates 21, so that all hydraulic cylinders 22 are provided on the side of the two pressing plates 21 away from each other.

[0045] A plurality of cones 23 are respectively provided on the sides of the two pressing plates 21 that are close to each other. The cones 23 on the same pressing plate 21 are evenly distributed in a matrix, and the tips of all the cones 23 are away from the pressing plate 21 .

[0046] Under the action of all the hydraulic cylinders 22, the two pressing plates 21 move synchronously and move closer to or away from each other.

[0047] In addition, the hydraulic cylinder 22 is equipped with a hydraulic system to achieve the purpose of accurately controlling the movement of the hydraulic cylinder 22.

[0048] The motor 31 is arranged outside the housing 10 , and its output shaft penetrates into the interior of the secondary crushing area 14 , and the output shaft of the motor 31 is rotatably connected to the housing 10 via a bearing.

[0049] One end of the main shaft 32 is rotatably disposed inside the secondary crushing zone 14 , and the other end of the main shaft 32 is coaxially disposed on the output shaft of the motor 31 , so that the motor 31 can directly drive the main shaft 32 to rotate.

[0050] There are multiple hammer bodies 33 , one end of each hammer body 33 is rotatably connected to the main shaft 32 , and the hammer body 33 and the main shaft 32 are vertically connected.

[0051] During operation, all ores are fed into the primary crushing zone 13 from the feed port 11 at the top of the shell 10. In the primary crushing zone 13, the larger ores are crushed to miniaturize their volume through the hydraulic cylinder 22, the pressure plate 21 and the cone 23. Then, the small-volume ores entering the primary crushing zone 13 will directly enter the secondary crushing zone 14 through the gaps between the larger ores.

[0052] In the secondary crushing zone 14, small ore crushed from large ore and small ore directly entering the secondary crushing zone are directly hammered into smaller pieces by the action of the motor 31, the main shaft 32, and all the hammers 33. The ore discharged through the discharge port 12 at the bottom of the housing 10 can meet transportation requirements.

[0053] This technical solution does not require preliminary screening of the mined ore, nor does it require transportation of large volumes of ore after preliminary crushing, thereby simplifying the entire crushing process and achieving the goal of efficient crushing.

[0054] In one specific embodiment:

[0055] The high-efficiency crusher further includes a plurality of crossbars 40, all of which are arranged parallel to each other in the housing 10 so that all of the crossbars 40 are located on the same plane. Furthermore, all of the crossbars 40 are located between the primary crushing zone 13 and the secondary crushing zone 14, thereby separating the primary crushing zone 13 from the secondary crushing zone 14.

[0056] In addition, all cross bars 40 are close to the bottom of the pressure plate 21 , and the spacing between adjacent cross bars 40 needs to meet the crushing requirements, that is, only ores that meet the required size after being crushed in the primary crushing zone 13 can enter the secondary crushing zone 14 .

[0057] In this embodiment, the purpose of providing the crossbar 40 is to control the size of the ore after crushing.

[0058] In another specific embodiment:

[0059] The pressure plate 21 includes two plates 211, which are rectangular structures. The sides of the two plates 211 are connected to each other, and the length directions of the two plates 211 are consistent. At the same time, there is an angle between the plate surfaces of the two plates 211, so that a V-shaped structure is formed between the two plates 211, and the angle between the two plates 211 is greater than 90° and less than 180°.

[0060] The two pressing plates 21 are arranged in a symmetrical structure, and the sides of the two pressing plates 21 with an angle greater than 90° and less than 180° are close to each other, and a plurality of cones 23 are arranged on this side of the pressing plate 21.

[0061] In this embodiment, by designing the pressing plates 21 into a V-shaped structure, the two pressing plates 21 can wrap the ore, thereby preventing the ore from escaping from the primary crushing zone 13 during the squeezing process.

[0062] In another specific embodiment:

[0063] The pressure plate 21 further includes a baffle 212 , which is disposed on top of the two plates 211 and forms a Z-shaped structure with the two plates 211 .

[0064] In addition, a window 15 is provided on both sides of the primary crushing area 13 of the housing 10 , and the hydraulic cylinder 22 penetrates into the primary crushing area 13 through the window 15 and is connected to the pressing plate 21 .

[0065] In this embodiment, by providing a window 15 on the primary crushing zone 13 , the movable space of the pressing plate 21 can be increased. The baffle 212 is provided to prevent small-sized ores from escaping from the window 15 .

[0066] In another specific embodiment:

[0067] The main shaft 32 includes a support plate 321 and a connecting shaft 322 , wherein the support plate 321 is a circular structure. There are two support plates 321 , and both are located in the secondary crushing area 14 .

[0068] One of the support plates 321 is coaxially disposed on the end of the output shaft of the motor 31 , and the other support plate 321 is rotatably disposed on the inner wall of the housing 10 , and the two support plates 321 are coaxially disposed.

[0069] A plurality of connecting shafts 322 are provided between the two support plates 321 . All the connecting shafts 322 are evenly distributed around the axis of the support plates 321 , and there is a distance between two adjacent connecting shafts 322 .

[0070] In this embodiment, all hammers 33 are rotatably arranged on the connecting shaft 322, so that each connecting shaft 322 is provided with multiple hammers 33. In addition, in order to avoid collision between adjacent hammers 33, the hammers 33 on two adjacent connecting shafts 322 are staggered.

[0071] In another specific embodiment:

[0072] Since the ore is crushed in the primary crushing zone 13, the overall space occupied is reduced. Therefore, the middle portion of the housing 10 is configured to be inwardly contracted, making the width of the primary crushing zone 13 larger than that of the secondary crushing zone 14. This improves the crushing rate in the secondary crushing zone 14.

[0073] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
