[0008] Furthermore, an extension plate is provided at the bottom end of the crushing plate, and the bottom surface of the extension plate provided at the bottom end of the crushing plate is wedge-shaped; the adjusting assembly includes a wedge-shaped slider abutting the bottom surface of the crushing plate and an adjusting compression spring connected to the wedge slider; a horizontal support plate is provided on the side wall of the shell, and the wedge slider is placed on the support plate; one end of the adjusting compression spring abuts the side wall of the shell, and the other end abuts the wedge slider.

[0009] Furthermore, a plurality of cylindrical grooves arranged at intervals are provided on the wall surface of the crushing plate facing the toothed roller, and the cylindrical grooves are opposite to the teeth on the toothed roller.

[0010] Furthermore, a sieve plate is provided below the tooth roller, and the sieve plate is provided with evenly distributed sieve holes in the part close to the crushing plate, and a feeding gap is formed between the sieve plate and the shell, and the size of the sieve holes is smaller than the size of the feeding gap; a first conveyor belt and a second conveyor belt are provided below the sieve plate, the first conveyor belt is opposite to the sieve holes, and the second conveyor belt is opposite to the feeding gap.

[0011] Furthermore, the screen plate is arranged to be inclined from top to bottom from one side close to the crushing plate to the other side.

[0012] Furthermore, the sieve plate is fixedly connected to the extension plate.

[0013] Furthermore, the screen plate is arranged to be tilted from top to bottom from one end close to the small diameter end of the gear roller to the other end.

[0014] Furthermore, two toothed rollers are provided in the shell, and the two toothed rollers are symmetrically arranged on both sides of the crushing plate; and the rotation directions of the two toothed rollers are opposite.

[0015] The beneficial effects of the present invention are: The integrated pulverizer for sulfide iron ore raw materials of the present invention utilizes a tapered tooth roller so that the speed of movement and crushing force of the teeth on the roller vary with the radial dimensions of the roller.

By providing a rotatable housing that rotates the roller, the ratio of raw material distributed on the roller varies with the roller's deflection. The ratio of raw material at the smaller diameter end of the roller is positively correlated with the size and hardness of the raw material, while the ratio of raw material at the larger diameter end is negatively correlated with the size and hardness of the raw material. The teeth with greater crushing force at the smaller diameter end crush more large or high-hardness raw material, while the teeth with greater speed at the larger diameter end crush more small or low-hardness raw material. This ensures that the ratio of raw material at the smaller and larger diameter ends of the roller is aligned with the size and hardness of the raw material, ensuring effective crushing and improving crushing efficiency while also reducing the risk of the roller becoming stuck.

[0022] Refer to the following Figures 1 to 10 The integrated crusher for sulfide iron ore raw materials provided by the present invention is described.

[0023] This embodiment provides an integrated crusher for sulfide iron ore raw materials. The integrated crusher for sulfide iron ore raw materials generally includes: a support 100 , a crushing plate 300 , and a tooth roller 400 .

[0024] A rotatable housing 200 is mounted on the support 100. A crushing plate 300 is vertically mounted within the housing 200. A conical toothed roller 400 is rotatably mounted within the housing 200, with a gap between it and the crushing plate 300. The ends of the toothed roller 400 are rotatably connected to two opposing side walls of the housing 200, and as the toothed roller 400 rotates, it drives the raw material toward the crushing plate 300. The housing 200 is configured to adjust its rotation angle based on the size and hardness of the raw material, causing the toothed roller 400 to deflect and alter the proportion of raw material distributed on the toothed roller 400. The proportion of raw material at the small-diameter end 420 of the toothed roller 400 is positively correlated with the size and hardness of the raw material.

[0025] In this embodiment, by providing a tapered toothed roller 400, the movement speed and crushing force of the teeth 410 on the toothed roller 400 vary with the radial dimension of the toothed roller 400. The teeth 410 closer to the smaller diameter end 420 have a slower movement speed (i.e., lower crushing efficiency) and a greater crushing force. The teeth 410 closer to the larger diameter end 430 have a faster movement speed (i.e., higher crushing efficiency) and a lower crushing force.

[0026] By providing a rotatable shell 200, the shell 200 is used to drive the gear roller 400 to deflect, so that the raw material on the gear roller 400 slides in the axial direction of the gear roller 400, thereby changing the proportion of raw material distributed in various parts of the gear roller 400, so that the proportion of raw material at the large diameter end 430 and the small diameter end 420 of the gear roller 400 is adapted to the size and hardness of the raw material.

[0027] The proportion of raw material at the small-diameter end 420 of the gear roller 400 is positively correlated with the size and hardness of the raw material. Specifically, when the size or hardness of the raw material is larger, more of the raw material slides toward the small-diameter end 420 of the gear roller 400, where it is crushed by the teeth 410, which have greater crushing force. This not only improves the crushing effect but also reduces the risk of the gear roller 400 getting stuck. Conversely, the proportion of raw material at the large-diameter end 430 of the gear roller 400 is negatively correlated with the size and hardness of the raw material. Specifically, when the size and hardness of the raw material is smaller, more of the raw material slides toward the large-diameter end 430 of the gear roller 400, where it is crushed by the teeth 410, which have a higher moving speed, thereby improving crushing efficiency.

[0028] like Figure 1-5As shown, a hinge column 210 is provided on the shell 200, and a symmetrical bracket 110 is provided on the support 100. The shell 200 is arranged between the two brackets 110 and is hinged to the bracket 110 via the hinge column 210. A curved support plate 111 is provided at the top of the support 100, and a corresponding curved slide 220 is provided on the shell 200. The curved slide 220 is supported by the curved support plate 111 and is slidably connected to the curved support plate 111. The curvature of the curved support plate 111 and the curved slide 220 is consistent with the rotation arc of the shell 200. An open feed port 230 is formed on the top of the shell 200. The feed port 230 is funnel-shaped, allowing the raw materials to fall into the shell 200 more easily. The teeth 410 of the toothed roller 400 are tilted and form an acute angle with the rotation direction of the toothed roller 400. This can not only better drive the raw materials to move toward the crushing plate 300, but also enable the raw materials to be subjected to greater extrusion force when the toothed roller 400 and the crushing plate 300 cooperate to squeeze and crush the raw materials, thereby improving the crushing effect.

[0029] The gear roller 400 can generally be driven by a motor (not shown in the figure) to achieve self-rotation.

[0030] The crushing plate 300 has an inclined surface 310 facing the toothed roller 400, gradually approaching the toothed roller 400 from top to bottom. Furthermore, the crushing plate 300 is configured to move downward under the pressure of the toothed roller 400 when the material is large in size or hardness. An adjustment assembly 500 is located below the crushing plate 300 to push the crushing plate 300 upward.

[0031] As the size and hardness of the raw material increase, the pressure exerted by the raw material on the crushing plate 300 by the toothed roller 400 increases, and the crushing plate 300 moves downward vertically for a greater distance. As the size and hardness of the raw material decrease, the crushing plate 300 moves vertically upward under the push of the adjustment assembly 500, thereby achieving its reset.

[0032] In the solution of this embodiment, the crushing plate 300 is set to an inclined surface 310 towards the wall of the tooth roller 400, so that it gradually approaches the tooth roller 400 from bottom to top, and the crushing plate 300 is set to be pressed downward by the raw material driven by the tooth roller 400 when the size or hardness of the raw material is large, so that the gap between the tooth roller 400 and the crushing plate 300 increases with the increase of the size and hardness of the raw material, thereby avoiding the tooth roller 400 from getting stuck and improving the operation stability.

[0033] In some embodiments, two adjustment assemblies 500 may be provided below the crushing plate 300. The two adjustment assemblies 500 are respectively provided at both ends of the crushing plate 300 to jointly push the crushing plate 300 upward, so that the resetting effect of the crushing plate 300 is better.

[0034] A sliding guide plate 320 is provided at the top of the crushing plate 300, extending through the sidewall of the housing 200. The bottom surface of the sliding guide plate 320 is curved and abuts against the guide post 120 provided on the support 100. The crushing plate 300 is slidably connected to the sidewall of the housing 200, and a through slot 240 is formed in the sidewall of the housing 200 for the sliding guide plate 320 to move up and down. When the sliding guide plate 320 moves downward, the guide post 120 pushes against it, causing the crushing plate 300 to rotate, thereby driving the housing 200 to rotate. A guide groove 321 is provided on the bottom surface of the sliding guide block 121, and a corresponding guide block 121 is provided at the top of the guide post 120. A guide compression spring 322 is located within the guide groove 321. One end of the guide compression spring 322 abuts against the guide block 121, and the other end abuts against the wall of the guide groove 321 away from the crushing plate 300.

[0035] like Figure 5-6 As shown, in this embodiment, when the crushing plate 300 is not moving downward, the housing 200 remains vertical and does not rotate due to the pressure of the guide compression spring 322, and the generatrix at the top of the gear roller 400 tends to be horizontal. The distance between the curved wall of the gear roller 400 and the crushing plate 300 tends to be consistent, thereby ensuring that the size of the crushed raw materials tends to be consistent.

[0036] As the crushing plate 300 moves downward, the sliding guide plate 320, pushed by the guide post 120, slides along its bottom surface relative to the guide post 120, causing the crushing plate 300 to rotate as it moves downward. The rotation of the crushing plate 300 drives the housing 200, which in turn rotates the gear roller 400. This deflection tilts the generatrix at the top of the gear roller 400, causing the smaller diameter end 420 of the gear roller 400 to be lower than the larger diameter end 430, allowing more material to move toward the smaller diameter end 420 of the gear roller 400.

[0037] As the size or hardness of the raw material increases, the downward pressure on the crushing plate 300 increases, causing the crushing plate 300 to move downward a greater distance and a greater rotation angle of the crushing plate 300. The greater the rotation angle of the crushing plate 300, the greater the deflection angle of the housing 200 and the gear roller 400, resulting in a greater proportion of the raw material moving toward the small-diameter end 420 of the gear roller 400.

[0038] The solution of this embodiment, by providing a sliding guide plate 320 and a guide column 120, utilizes the movement of the crushing plate 300 to drive the deflection of the tooth roller 400, so that the deflection angle of the tooth roller 400 is positively correlated with the size and hardness of the raw material, thereby achieving self-adaptation of the raw material proportion on the tooth roller 400 and the size and hardness of the raw material.

[0039] In other embodiments, an integrated pulverizer for sulfide iron ore raw materials may be equipped with a detection device, a control system, and a drive device. The drive device is used to rotate the housing 200. The detection device is used to collect information about the size and hardness of the raw material. The numerical control system controls the drive device based on the size and hardness information of the raw material, thereby adjusting the rotation angle of the housing 200.

[0040] Furthermore, this embodiment provides a guide compression spring 322. The guide compression spring 322 pushes against the guide block 121, utilizing the preloaded force of the guide slot 321 to prevent the sliding guide plate 320 from sliding, thereby preventing the crushing plate 300 from moving downward. This prevents the crushing plate 300 from moving downward when the size and hardness of the raw material are relatively small. Furthermore, after the crushing plate 300 moves downward and the size and hardness of the raw material decrease, the guide compression spring 322 pushes the sliding guide plate 320 to slide back to its original position, thereby causing the crushing plate 300, the housing 200, and the toothed roller 400 to rotate and return to their original position.

[0041] In some embodiments, the hinge point between the housing 200 and the support 100 is located above the center of gravity of the housing 200. This allows the housing 200 to rotate and return to its original position under the weight of the housing 200 after the size and hardness of the raw material decreases. A counterweight may be provided below the center of gravity of the housing 200 to ensure that the housing 200 can be effectively restored under its own weight.

[0042] An extension plate 600 with a wedge-shaped bottom surface is provided at the bottom end of the crushing plate 300. The adjustment assembly 500 includes a wedge-shaped slider 510 that abuts the bottom surface of the extension plate 600 and an adjustment compression spring 520 connected to the wedge slider 510. A horizontal support plate 250 is provided on the side wall of the housing 200, and the wedge slider 510 rests on the support plate 250. One end of the adjustment compression spring 520 abuts the side wall of the housing 200, and the other end abuts the wedge slider 510.

[0043] In the solution of this embodiment, an extension plate 600 is provided at the bottom end of the crushing plate 300, the bottom surface of the extension plate 600 is set to be wedge-shaped, and an adaptive wedge-shaped slider 510 is provided. The wedge-shaped slider 510 is pushed by the adjustment compression spring 520, so that the wedge-shaped slider 510 moves horizontally along the support plate 250, thereby pushing the extension plate 600, and then pushing the crushing plate 300, so that the crushing plate 300 moves in the vertical direction.

[0044] In some embodiments, both ends of the bottom surface of the extension plate 600 are wedge-shaped. Two adjustment assemblies 500 are respectively disposed at both ends of the bottom surface of the extension plate 600, which jointly support and adjust the movement of the extension plate 600 and the crushing plate 300, making the movement of the extension plate 600 and the crushing plate 300 smoother and more stable. In some embodiments, the extension plate 600 and the crushing plate 300 can be integrally formed.

[0045] In other embodiments, the crushing plate 300 can directly cooperate with the adjustment assembly 500, the adjustment assembly 500 can be configured as a vertically arranged elastic member, a limiting hole can be provided on the bottom surface of the crushing plate 300, a horizontal support plate 250 is provided on the side wall of the shell 200, and a positioning hole is provided on the support plate 250, one end of the elastic member extends into the limiting hole, and the other end extends into the positioning hole.

[0046] like Figure 6-7 As shown, in some embodiments, a plurality of spaced cylindrical grooves 330 are provided on the wall surface of the crushing plate 300 facing the gear roller 400 , and the cylindrical grooves 330 are opposite to the teeth 410 on the gear roller 400 .

[0047] This embodiment provides cylindrical grooves 330 on the wall of the crushing plate 300, creating a wavy curved surface on the wall of the crushing plate 300, thereby enhancing the extrusion and crushing effect of the toothed roller 400 and the crushing plate 300. The cylindrical grooves 330 are arranged opposite the teeth 410 on the toothed roller 400, allowing the raw material to enter the gap formed between the teeth 410 of the toothed roller 400 and the cylindrical grooves 330. This not only enhances the shearing and extrusion effects on the raw material, resulting in a better crushing effect, but also allows the crushed raw material to fall smoothly along the vertical cylindrical grooves 330 and be discharged, reducing the risk of clogging and material jamming, and improving the operational stability of the equipment.

[0048] A sieve plate 700 is disposed below the toothed roller 400. The portion of the sieve plate 700 near the crushing plate 300 is provided with evenly distributed sieve holes 710. A material discharge gap 720 is formed between the sieve plate 700 and the housing 200. The sieve holes 710 are smaller than the material discharge gap 720. A first conveyor belt 130 and a second conveyor belt 140 are disposed below the sieve plate 700. The first conveyor belt 130 faces the sieve holes 710, and the second conveyor belt 140 faces the material discharge gap 720.

[0049] The solution of this embodiment is to classify the crushed raw materials according to their sizes by setting the screen plate 700, and output them respectively by the first conveyor belt 130 and the second conveyor belt 140, thereby improving the grading effect of the integrated crusher for sulfide iron ore raw materials.

[0050] like Figure 5As shown, the first conveyor belt 130 and the second conveyor belt 140 are mounted on the support 100. The second conveyor belt 140 is positioned below the first conveyor belt 130. It not only catches material (i.e., crushed raw materials) that falls from the discharge gap 720, but also catches material that falls from the first conveyor belt 130, thereby reducing the risk of material loss during transportation. The discharge port 260 of the housing 200 is funnel-shaped, guiding material toward the center of the second conveyor belt 140 for accumulation, thereby reducing the risk of material being transported by the second conveyor belt 140 from falling.

[0051] The screen plate 700 is arranged to be tilted from top to bottom from one side close to the crushing plate 300 to the other side.

[0052] In this embodiment, the screen plate 700 is arranged to slope downward from one side near the crushing plate 300 toward the other side. This allows the crushed raw materials to slide along the screen plate 700 away from the crushing plate 300 after sliding onto the screen plate 700, thereby improving the screening efficiency of the screen plate 700. As the raw materials slide, smaller materials fall through the screen holes 710, while larger materials slide to the edge of the screen plate 700 and fall through the material discharge gap 720.

[0053] The screen plate 700 is fixedly connected to the extension plate 600 and the crushing plate 300 .

[0054] In the solution of this embodiment, the screen plate 700 and the extension plate 600 are fixedly connected, so that the screen plate 700 moves synchronously with the extension plate 600. When the screen plate 700 moves, the crushed raw materials accumulated on the screen plate 700 vibrate and slide, thereby improving the screening efficiency of the screen plate 700.

[0055] like Figure 5 As shown, the thickness of the extension plate 600 is smaller than the thickness of the crushing plate 300, and the screen plate 700 is arranged below the crushing plate 300 and is fixedly connected to the extension plate 600, so that the raw materials sliding through the cylindrical groove 330 on the crushing plate 300 can all fall onto the screen plate 700, thereby ensuring the screening effect of the integrated crusher for sulfide iron ore raw materials.

[0056] In some embodiments, the extension plate 600 and the screen plate 700 may be integrally formed.

[0057] In some embodiments, a plurality of evenly distributed connecting columns are further provided below the sieve plate 700. One end of the connecting column is connected to the sieve plate 700, and the other end is connected to the extension plate 600, thereby improving the structural stability of the sieve plate 700.

[0058] The screen plate 700 is tilted downward from one end close to the small diameter end 420 of the gear roller 400 to the other end.

[0059] In the solution of this embodiment, the screen plate 700 is arranged to be inclined from top to bottom from one end close to the small diameter end 420 of the tooth roller 400 to the other end, so that after the crushed raw material slides onto the screen plate 700, it can not only slide from one side close to the crushing plate 300 to the other side, but also slide from one end close to the small diameter end 420 of the tooth roller 400 to the other end, thereby further improving the screening efficiency.

[0060] In some embodiments, the amount of raw material put into the shell 200 is negatively correlated with the size and hardness of the raw material. When the size or hardness of the raw material is large, the amount of raw material put into the shell 200 is small. The crushing plate 300 rotates synchronously when it moves downward under the pressure of the raw material, driving the extension plate 600 to rotate synchronously, thereby driving the screen plate 700 to rotate. The screen plate 700 rotates so that the projection of the connecting line between the screen plate 700 and the extension plate 600 in the vertical direction tends to be horizontal, thereby extending the residence time of the crushed raw material on the screen plate 700 and accumulating more raw material on the screen plate 700. Not only can the screening accuracy be improved, but also after the amount of raw material put in is reduced, the gravity of the raw material can be used to keep the extension plate 600 and the crushing plate 300 in the downward state, thereby reducing the risk of the tooth roller 400 being stuck.

[0061] Two gear rollers 400 are arranged in the housing 200 . The two gear rollers 400 are symmetrically arranged on both sides of the crushing plate 300 . The two gear rollers 400 rotate in opposite directions.

[0062] The solution of this embodiment is to set two tooth rollers 400 symmetrically arranged about the crushing plate 300 in the shell 200, and set the two tooth rollers 400 to rotate in opposite directions, so that the two tooth rollers 400 cooperate with the crushing plate 300 to crush, thereby improving the crushing efficiency.

[0063] like Figure 5 As shown, the sidewalls of the crushing plate 300 facing the two toothed rollers 400 are inclined surfaces 310, gradually approaching the toothed rollers 400 from top to bottom, and are spaced apart with multiple cylindrical grooves 330. A sieve plate 700 is correspondingly provided below each of the two toothed rollers 400.

[0064] The specific working process of the integrated crusher for sulfide iron ore raw materials provided by the present invention is described in combination with the above embodiments: The motor is started to rotate the gear roller 400. The raw material enters the housing 200 from the feed port 230, is driven by the gear roller 400, moves between the gear roller 400 and the crushing plate 300, is crushed under the pressure of the gear roller 400 and the crushing plate 300, and then falls from the gap between the gear roller 400 and the crushing plate 300 onto the screen plate 700.

[0065] After the crushed raw materials fall onto the screen plate 700, the smaller part falls onto the first conveyor belt 130 through the screen holes 710, and the larger part slides along the inclined direction of the screen plate 700, and then falls onto the second conveyor belt 140 through the discharge gap 720 between the screen plate 700 and the shell 200.

[0066] During the crushing process, the toothed roller 400 rotates, moving the material and collaborating with the crushing plate 300 to squeeze it. When the material is large or hard, the crushing plate 300 moves downward under the pressure of the material. As the crushing plate 300 moves downward, the sliding guide plate 320, supported by the guide post 120, slides, causing the crushing plate 300 to rotate synchronously, thereby driving the housing 200 to rotate synchronously. The rotation of the housing 200 causes the toothed roller 400 to deflect, causing the small-diameter end 420 of the toothed roller 400 to be lower than the large-diameter end 430. This causes more of the material that has fallen into the housing 200 to move to the small-diameter end 420 of the toothed roller 400. This allows the teeth 410 of the small-diameter end 420 of the toothed roller 400, which have greater crushing force, to crush the material, thereby improving the crushing effect.

[0067] The amount of raw material fed into the sieve is inversely correlated with its size and hardness. After the crushing plate 300 rotates, the extension plate 600 drives the sieve plate 700 to rotate synchronously, causing the vertical projection of the sidewall of the sieve plate 700 near the extension plate 600 to become horizontal. This allows the raw material to remain on the sieve plate 700 longer. This improves screening accuracy while also allowing more raw material to accumulate on the sieve plate 700. Consequently, even when the amount of raw material fed into the sieve is reduced, the weight of the material keeps the extension plate 600 and crushing plate 300 in their downward position.

[0068] After the size and hardness of the raw material decrease, the compression spring 520 is adjusted to push the wedge-shaped slider 510, causing it to move along the support plate 250 toward the interior of the housing 200. The wedge-shaped slider pushes the extension plate 600, which in turn pushes the crushing plate 300, causing it to move upward. After the crushing plate 300 moves upward, the guide compression spring 322 between the guide block 121 and the wall of the guide groove 321 pushes the sliding guide plate 320 back to its original position, driving the crushing plate 300 to rotate and reset, thereby driving the housing 200 to rotate and reset, and further driving the gear roller 400 to rotate and reset.

[0069] During the process of the crushing plate 300 moving up and down and rotating, the screen plate 700 is driven by the extension plate 600 to move and rotate synchronously, so that the raw materials on the screen plate 700 vibrate, thereby increasing the screening efficiency.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments merely illustrate several embodiments of the present invention, and 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 various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
