[0050] The present utility model will be further described below with reference to the accompanying drawings:

[0051] In this embodiment:

[0052] Please refer to Figures 1-5 , in this embodiment: A roller crusher includes: a machine shell 1, a top cover 2, two groups of baffles 16, two groups of crushing components and an extrusion device.

[0053] In this embodiment, a feed inlet is provided on the upper end surface of the machine shell 1; the top cover 2 is arranged directly above the machine shell 1 and is fixedly connected to the machine shell 1 through two groups of connecting rods 3.

[0054] In this embodiment, ore is added into the machine shell 1 through the feed inlet.

[0055] Both groups of baffles 16 are arranged at the feed inlet for controlling the movement of the ore.

[0056] In this embodiment, the ore will slide downward along the surface of the baffle 16, and the upper surface of the baffle 16 is an inclined surface.

[0057] Two sets of crushing components are arranged inside the casing 1 for crushing ores; an extrusion device is arranged inside the top cover 2 for extruding ores; the extrusion device includes: an extrusion plate 9, which is arranged directly above the feed inlet, and the extrusion plate 9 can enter the inside of the casing 1 through the feed inlet.

[0058] In this embodiment, the extrusion device pushes the extrusion plate 9 to move vertically downward, and the extrusion plate 9 will extrude the ores. At the same time, the moving space of the ores is compressed, so that the ores can be quickly crushed and the crushing efficiency can be improved.

[0059] As Figure 2 and Figure 4 shown, the extrusion device further includes: a worm 14, a second motor 15, two sets of worm wheels 13, two sets of rotating rods 12, two sets of first moving members 11 and two sets of connecting plates 10.

[0060] Specifically, the thread directions on both sides of the worm 14 are opposite; the output end of the second motor 15 is fixedly connected to one end of the worm 14; two sets of worm wheels 13 are both arranged below the worm 14 and are meshed with the worm 14.

[0061] In this embodiment, the model of the second motor 15 is selected according to actual needs as long as it meets the working conditions; the output end of the second motor 15 drives the worm 14 to rotate. Since the thread directions on both sides of the worm 14 are opposite, the rotating directions of the two sets of worm wheels 13 are opposite.

[0062] One end of each set of rotating rods 12 is fixedly connected to the axis of the worm wheel 13.

[0063] In this embodiment, the worm wheel 13 can drive the rotating rod 12 to rotate synchronously.

[0064] The other end of the rotating rod 12 is provided with a first sliding groove; the surface of each set of first moving members 11 is provided with a first cylindrical pin, and the first cylindrical pin is arranged in the first sliding groove and is slidably connected to the rotating rod 12 through the first sliding groove.

[0065] In this embodiment, when the rotating rod 12 rotates, the first moving member 11 will move vertically through the sliding between the first sliding groove and the first cylindrical pin.

[0066] One end of each set of connecting plates 10 is fixedly connected to the first moving member 11, and the other end is fixedly connected to the upper end surface of the extrusion plate 9.

[0067] In this embodiment, the first moving member 11 can drive the extrusion plate 9 to move vertically through the connecting plate 10.

[0068] The length of the extrusion plate 9 is less than the distance between the two sets of baffles 16.

[0069] After pouring the ore into the casing 1, start the second motor 15, and the output end of the second motor 15 drives the worm 14 to rotate; since the thread directions on both sides of the worm 14 are opposite, the rotation directions of the two sets of worm wheels 13 are opposite; the worm wheels 13 drive the rotating rods 12 to rotate synchronously; the rotating rods 12 slide through the first chute and the first cylindrical pin, so that the first moving member 11 moves vertically downward; the first moving member 11 drives the pressing plate 9 to move vertically through the connecting plate 10; the pressing plate 9 will extrude the ore, and at the same time compress the moving space of the ore, which can quickly crush the ore and improve the crushing efficiency.

[0070] As Figure 1 and Figure 2 shown, each set of crushing components includes: two sets of sliding blocks 5, crushing rollers 4, electric push rods 6 and first motors 7.

[0071] Among them, each set of sliding blocks 5 is slidably connected to the casing 1 through a slideway opened on the surface of the casing 1.

[0072] In this embodiment, the length of the slideway is short, and the inner diameter is smaller than the cross-sectional area of the crushing roller 4, so that when the crushing roller 4 moves, the ore will not leak out from the slideway.

[0073] Both ends of the crushing roller 4 penetrate through the corresponding positions of the two sets of sliding blocks 5 and are slidably connected to the sliding blocks 5; the output end of the electric push rod 6 is fixedly connected to the surface of the sliding block 5.

[0074] In this embodiment, by making the output end of the electric push rod 6 stretch and retract, the horizontal position of the sliding block 5 is adjusted, so as to change the position of the crushing roller 4; the model of the electric push rod 6 is selected according to actual needs as long as it meets the working conditions.

[0075] The output end of the first motor 7 is fixedly connected to one end of the crushing roller 4 close to the electric push rod 6; a bracket is arranged on the surface of the first motor 7, and the bracket is slidably connected to the casing 1.

[0076] In this embodiment, the output end of the first motor 7 can drive the crushing roller 4 to rotate; the model of the first motor 7 is selected according to actual needs as long as it meets the working conditions.

[0077] The roller crusher further includes: two sets of guide plates 22; the two sets of guide plates 22 are both arranged below the crushing roller 4; the two sets of guide plates 22 are in an inclined state, and the upper ends of the two sets of guide plates 22 are butted to control the moving direction of the ore.

[0078] The roller crusher further includes: two sets of discharge ports 8; the two sets of discharge ports 8 are symmetrically arranged on both sides of the casing 1, and the discharge ports 8 are located at the lower ends of the guide plates 22.

[0079] In this embodiment, the crushed ore will move along the upper surface of the guide plate 22 to the discharge port 8.

[0080] During the crushing process, when the ore is relatively hard, the crushing roller 4 may get stuck, which requires manual maintenance, causing inconvenience.

[0081] To solve the above problems, this embodiment proposes an implementation method. The roll crusher further includes: a dredging device; the dredging device is arranged inside the casing 1 and is located below the two groups of guide plates 22.

[0082] In this embodiment, as Figure 2 and Figure 3 shown, the dredging device includes: two groups of seals 23, a top plate 24, a second moving member 25, an inclined plate 26, a moving plate 27, a threaded rod 28, and a fourth motor 29.

[0083] Specifically, the two groups of seals 23 are both arranged at the upper ends of the two groups of guide plates 22 and are fixedly connected to the guide plates 22; the top plate 24 is arranged between the two groups of seals 23 and is tightly connected to the two groups of seals 23.

[0084] In this embodiment, the seal 23 is made of rubber material and is used to seal the upper ends of the two groups of guide plates 22 to prevent crushed stones from leaking through the gaps.

[0085] The second moving member 25 is arranged at the bottom end of the top plate 24 and is fixedly connected to the top plate 24.

[0086] In this embodiment, the second moving member 25 can push the top plate 24 to move vertically.

[0087] The surface of the second moving member 25 is provided with a second cylindrical pin; the surface of the inclined plate 26 is provided with a second chute and is slidably connected to the second cylindrical pin through the second chute; the bottom end of the moving plate 27 is fixedly connected to the surface of the inclined plate 26.

[0088] In this embodiment, when the moving plate 27 moves horizontally, it will drive the inclined plate 26 to move synchronously. The inclined plate 26 makes the second moving member 25 move vertically through the sliding between the second chute and the second cylindrical pin.

[0089] One end of the threaded rod 28 penetrates through the corresponding position of the moving plate 27 and is threadedly connected to the moving plate 27; the output end of the fourth motor 29 is fixedly connected to the other end of the threaded rod 28.

[0090] In this embodiment, the model of the fourth motor 29 is selected according to actual needs as long as it meets the working conditions; the output end of the fourth motor 29 can drive the threaded rod 28 to rotate, and the threaded rod 28 makes the moving plate 27 move horizontally.

[0091] When dredging is required, the fourth motor 29 is started, and the output end of the fourth motor 29 drives the threaded rod 28 to rotate; the threaded rod 28 causes the moving plate 27 to move horizontally; the moving plate 27 drives the inclined plate 26 to move synchronously; the inclined plate 26 slides through the second chute and the second cylindrical pin, so that the second moving member 25 moves vertically upward; the second moving member 25 pushes the top plate 24 to move, and the top plate 24 will push out the crushed stones stuck between the crushing rollers 4, eliminating the need for manual maintenance, which is more convenient.

[0092] When adjusting the distance between the two groups of crushing rollers 4, since the position of the baffle 16 is fixed, when the crushing rollers 4 move towards the middle, the gap between the crushing rollers 4 and the baffle 16 will be relatively large, resulting in some ores falling to the lower part from the gap, causing incomplete crushing.

[0093] To solve the above problems, this embodiment proposes an implementation manner. The roller crusher further includes: an adjusting device; the adjusting device is arranged on both sides inside the machine housing 1 and is fixedly connected to the baffle 16 for adjusting the position of the baffle 16.

[0094] In this embodiment, as Figure 2 and Figure 5 shown, the adjusting device includes: a turntable 19, a bevel gear set 20, a third motor 21, a rotating member 18 and a moving rod 17.

[0095] Among them, a round rod is arranged on the surface of the turntable 19; the bevel gear set 20 is composed of a first bevel gear and a second bevel gear, and the edge of the first bevel gear is meshed and connected with the edge of the second bevel gear; the second bevel gear is coaxially arranged with the turntable 19; the output end of the third motor 21 is fixedly connected to the axis of the first bevel gear.

[0096] In this embodiment, the model of the third motor 21 is selected according to actual needs as long as it meets the working conditions; the output end of the third motor 21 drives the bevel gear set 20 to rotate, and the bevel gear set 20 drives the turntable 19 to rotate at the same time.

[0097] One end of the rotating member 18 is rotatably connected to the round rod.

[0098] In this embodiment, when the turntable 19 rotates, it will drive the round rod to do a circular motion, and the round rod will cause the rotating member 18 to move horizontally while rotating slightly.

[0099] The moving rod 17 is arranged between the rotating member 18 and the baffle 16. One end of the moving rod 17 is rotatably connected to the other end of the rotating member 18, and the other end is fixedly connected to the baffle 16.

[0100] In this embodiment, the rotating member 18 will drive the moving rod 17 to move horizontally, and the moving rod 17 will drive the baffle 16 to move at the same time.

[0101] When it is necessary to adjust the position of the baffle 16, start the third motor 21. The output end of the third motor 21 drives the bevel gear set 20 to rotate; the bevel gear set 20 drives the turntable 19 to rotate at the same time; the turntable 19 causes the round rod to move in a circular motion, and the round rod causes the rotating member 18 to move horizontally while rotating slightly; the rotating member 18 pulls the moving rod 17 to move horizontally; the moving rod 17 drives the baffle 16 to move; the position of the baffle 16 can be adjusted according to the position of the crushing roller 4, so that the gap between the crushing roller 4 and the baffle 16 is kept within a certain range, preventing crushed stones from falling below through the gap.

[0102] Working principle:

[0103] When this roller crusher is in use, the user pours the ore into the machine housing 1 from the feed inlet; then, according to the needs, adjust the distance between the two groups of crushing rollers 4; by making the output end of the electric push rod 6 extend and retract, drive the sliding block 5 to move, thereby driving the crushing roller 4 to move; after reaching the specified position, start the first motor 7, and the output end of the first motor 7 drives the crushing roller 4 to rotate to start crushing.

[0104] After the adjustment is completed, start the third motor 21. The output end of the third motor 21 drives the bevel gear set 20 to rotate; the bevel gear set 20 drives the turntable 19 to rotate at the same time; the turntable 19 causes the round rod to move in a circular motion, and the round rod causes the rotating member 18 to move horizontally while rotating slightly; the rotating member 18 pulls the moving rod 17 to move horizontally; the moving rod 17 drives the baffle 16 to move; the position of the baffle 16 can be adjusted according to the position of the crushing roller 4, so that the gap between the crushing roller 4 and the baffle 16 is kept within a certain range, preventing crushed stones from falling below through the gap.

[0105] At the same time, start the second motor 15. The output end of the second motor 15 drives the worm 14 to rotate; since the thread directions on both sides of the worm 14 are opposite, the rotation directions of the two groups of worm wheels 13 are opposite; the worm wheels 13 drive the rotating rods 12 to rotate synchronously; the rotating rods 12 move vertically downward through the sliding between the first sliding groove and the first cylindrical pin; the first moving member 11 drives the pressing plate 9 to move vertically through the connecting plate 10; the pressing plate 9 squeezes the ore and at the same time compresses the moving space of the ore, which can quickly crush the ore and improve the crushing efficiency.

[0106] When it is necessary to dredge, start the fourth motor 29. The output end of the fourth motor 29 drives the threaded rod 28 to rotate; the threaded rod 28 makes the moving plate 27 move horizontally; the moving plate 27 drives the inclined plate 26 to move synchronously; the inclined plate 26 moves vertically upward through the sliding between the second sliding groove and the second cylindrical pin; the second moving member 25 pushes the top plate 24 to move, and the top plate 24 will push out the crushed stones stuck between the crushing rollers 4, eliminating the need for manual maintenance, which is more convenient.

[0107] The crushed gravel will move along the upper surface of the diversion plate 22 to the discharge port 8, and be discharged from the casing 1, thus completing the use of this device.
