The feed hopper and the two through holes form the feed inlet. The through hole in the front first disc body is located between the transmission shaft and the striking ring body structure.

[0020] A multi-functional crusher of the present invention, during application, since the feeding port directly faces the output end of the second driving device, when the material enters from the feeding port, the material collides with the output end of the second driving device. At this time, under the driving action of the second driving device, the output end of the second driving device and the first striking ring rotate synchronously at high speed. The rotation of the output end of the second driving device throws the material falling from the feeding port at high speed, causing the material to collide with the first striking rods on the first striking ring. The high-speed rotation of the first striking ring throws the material inside the first striking ring at high speed and collides with the second striking rods on the second striking ring. Under the action of the first driving device, the output end of the first driving device and the second striking ring rotate synchronously, so that the second striking rods on the second striking ring throw the material inside the second striking ring at high speed onto the inner side wall of the housing, and then pass through the feeding gap and finally fall from the falling port; if the material needs to be crushed, then control the rotation directions of the output ends of the first driving device and the second driving device to be the same, and the crushing of the material can be achieved. If the material needs to be depolymerized, then control the rotation directions of the output ends of the first driving device and the second driving device to be opposite. For example, the rotation direction of the output end of the first driving device is clockwise and the rotation direction of the output end of the second driving device is counterclockwise, or the rotation direction of the output end of the first driving device is counterclockwise and the rotation direction of the output end of the second driving device is clockwise. At this time, the depolymerization treatment of the material formed by different materials can be carried out; moreover, the first striking ring and the second striking ring are provided with several circles, and the material sequentially passes through each first striking ring and each second striking ring from the innermost first striking ring and is thrown into the range of the outermost second striking ring. In this way, under continuous impact, the crushing efficiency of the material can be greatly improved. Furthermore, the number of each first striking rod and each second striking rod can be adjusted, that is, the distance between two adjacent first striking rods and the distance between two adjacent second striking rods can be adjusted. If this distance is larger, larger materials can be crushed or depolymerized. If the distance is smaller, smaller materials can be crushed or depolymerized to achieve fine crushing, produce fine powder of 0 - 5 mm, or separately produce fine powder of less than 75 μm, so as to meet the processing requirements of products of various finenesses; compared with the prior art, by controlling the rotation directions of the output ends of the first driving device and the second driving device, the material is impacted to different degrees within the first striking ring and the second striking ring to achieve the crushing, depolymerization or powder making treatment of the material. The crushing specifications of the material that can be crushed are more, and the types of materials that can be processed are also more. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to further explain the technical solution of the present invention, the following will be elaborated in detail with reference to the accompanying drawings.

[0028] A multifunctional crusher, as Figures 1-6 shown, includes a housing 1 and a crushing roller. The crushing roller is rotatably installed in the housing 1. The crushing roller is provided with striking members for striking materials. The housing 1 is provided with a feeding port 100 and a discharging port 200. The housing 1 is provided with a rotation driving device for driving the crushing roller to rotate. During application, the rotation driving device drives the crushing roller to rotate and then drives the striking members to rotate. Then, the materials enter from the feeding port 100. The high-speed movement of the striking members causes the materials to be thrown outwards, thereby crushing the materials. After crushing, the materials fall from the discharging port.

[0029] The crushing roller has four disk bodies. Two of the disk bodies are first disk bodies. The two first disk bodies are arranged transversely opposite to each other to form a first turntable. The other two disk bodies are second disk bodies. The two second disk bodies are arranged transversely opposite to each other to form a second turntable. The directions in which the two first disk bodies and the two second disk bodies face each other are both the front-rear direction. The two first disk bodies and the two second disk bodies are all rotatably installed in the housing 1. Among the two first disk bodies, one first disk body is located between the two second disk bodies and is in close contact with one of the second disk bodies. Among the two second disk bodies, one second disk body is located between the two first disk bodies. Taking the first disk body at the front side as the front first disk body 21, the first disk body at the rear side as the rear first disk body 22, the second disk body at the front side as the front second disk body 31, and the second disk body at the rear side as the rear second disk body 32. Specifically, the rear second disk body 32 is located at the rear side of the rear first disk body 22 and is in close contact with it. The front second disk body 31 is located at the rear side of the front first disk body 21. The front first disk body 21, the rear first disk body 22, the front second disk body 31, and the rear second disk body 32 are all circular structures. The axis lines of the front first disk body 21, the rear first disk body 22, the front second disk body 31, and the rear second disk body 32 are on the same straight line. A circular hole penetrating through the front and rear is provided on the front second disk body 31.

[0030] A first striking ring is connected between the two first discs. The first striking ring is composed of a number of first striking rods 4 that are circumferentially spaced around the first disc. A second striking ring is connected between the two second discs. The second striking ring is composed of a number of second striking rods 5 that are circumferentially spaced around the second disc. The above-mentioned first striking ring and second striking ring are each provided with a number of rings. Each first striking ring and each second striking ring are sleeved and matched with each other from the inside to the outside in sequence. And there is a second striking ring between two adjacent first striking rings. Each second striking ring and each first striking ring form a striking ring body structure that combines crushing and depolymerization. And the innermost ring in the striking ring body structure is the first striking ring, and the outermost ring is the second striking ring. Each of the first striking rods 4 and each of the second striking rods 5 constitute the striking members. Taking the example that each of the first striking ring and the second striking ring is provided with one ring, at this time, there is the innermost first striking ring and the outermost second striking ring. The material enters the first striking ring. Under the rotational cooperation of the two first discs, it drives the first striking rods to rotate circumferentially and throws the material outwards into the second striking ring. Taking the example that each of the first striking ring and the second striking ring is provided with two rings, at this time, the innermost ring is the first ring, the first ring is the first striking ring, the second ring is the second striking ring, the third ring is the first striking ring, and the fourth ring is the second striking ring. The inner diameters of the first ring to the fourth ring increase in sequence. The first striking ring of the first ring and the first striking ring of the third ring move synchronously under the rotation of the two first discs. The second striking ring of the second ring and the second striking ring of the fourth ring move synchronously under the rotation of the two second discs. The material enters the first striking ring of the first ring. The two first discs rotate and throw the material onto the second striking ring of the second ring. The two second discs rotate and throw the material into the first striking ring of the third ring. At this time, since the first striking ring of the third ring rotates synchronously with the first striking ring of the first ring, the first striking ring of the third ring throws the material into the range of the second striking ring of the fourth ring.

[0031] There is a material passing gap between the hitting ring structure and the inner side wall of the housing 1; specifically, the housing 1 includes a left plate body 11, a right plate body 12, a front plate body 13, a rear plate body 14 and an upper plate body 15. The left plate body 11, the right plate body 12, the front plate body 13 and the rear plate body 14 are all erected and enclose a hollow square frame. The upper plate body 15 is clamped between the front plate body 13 and the rear plate body 14. The left plate body 11 and the right plate body 12 are clamped between the front plate body 13 and the rear plate body 14. The upper plate body 15 has an inclined plate 151 and a horizontal straight plate 152. The horizontal straight plate 152 extends in the left-right direction. There are two inclined plates 151. The two inclined plates 151 incline downward, and the upper ends of the two inclined plates 151 are respectively connected to the left and right sides of the horizontal straight plate 152. The lower ends of the two inclined plates 151 are respectively connected to the upper ends of the left plate body 11 and the right plate body 12, that is, the two inclined plates 151 form a horn structure that gradually expands from top to bottom. The above-mentioned crushing roller is in the hollow chamber of the hollow square frame. The bottom open mouth of the hollow square frame is the material discharging port. The distance between the second hitting ring and the inner side wall of the hollow square frame is the material passing gap; preferably, a front rotating groove 300 for the front first disc body 21 to rotate therein is formed on the front plate body 13. The front first disc body 21 is within the hollow range of the front second disc body 31. A rear rotating groove 400 for the rear second disc body 32 to rotate therein is formed on the rear plate body 14. The rear first disc body 22 is on the front side of the rear second disc body 32; during application, the second hitting ring at the outermost circle throws the material out again into the material passing gap range and finally falls from the material discharging port; furthermore, the front end of the front first disc body 21 rotates in the front rotating groove 300, so that the front first disc body 21 can move better in a predetermined track during rotation and is not easily offset; similarly, the rear end of the rear second disc body 32 rotates in the rear rotating groove 400, so that the rear second disc body 32 can move better in a predetermined track during rotation and is not easily offset.

[0032] The first end of the first striking rod 4 is connected to one of the first discs, and the second end of the second striking rod 5 is connected to the other first disc. The first end of the second striking rod 5 is connected to one of the second discs, and the second end of the second striking rod 5 is connected to the other second disc. Specifically, both the first striking rod 4 and the second striking rod 5 are cylindrical rod structures extending in the front-rear direction. The two ends of the first striking rod 4 are respectively locked and connected to the front first disc 21 and the rear first disc 22 through first bolts, and the front first disc 21 and the rear first disc 22 are both provided with first fixing holes 500 for the first bolts to pass through. There are several first fixing holes 500, and each first fixing hole 500 is evenly spaced in the circumferential direction. The first fixing holes 500 on the front first disc 21 are arranged in alignment with the first fixing holes 500 on the rear first disc 22 in the front-rear direction. First fixing screw grooves for the ends of the first bolts to be screwed into are recessed on the end faces of the two ends of the first striking rod 4. The two ends of the second striking rod 5 are respectively locked and connected to the front second disc 31 and the rear second disc 32 through second bolts, and the front second disc 31 and the rear second disc 32 are both provided with second fixing holes 600 for the second bolts to pass through. Second fixing screw grooves 700 for the ends of the second bolts to be screwed into are recessed on the end faces of the two ends of the second striking rod 5. During application, the first fixing screw grooves at the two ends of each first striking rod 4 are aligned with the corresponding first fixing holes 500 on the front first disc 21 and the rear first disc 22, and then each first striking rod 4 is locked on the first disc 2 through a first bolt. Similarly, the second fixing screw grooves at the two ends of the second striking rod 5 are aligned with the corresponding second fixing holes 600 on the front second disc 31 and the rear second disc 32, and then each second striking rod 5 is locked on the second disc 3 through a second bolt. Since the first striking rod 4 and the first disc 2 are detachably installed, and the second striking rod 5 and the second disc 3 are detachably installed, the relative distance between two adjacent first striking rods 4 or second striking rods 5 can be adjusted by installing an appropriate number of first striking rods 4 and second striking rods 5 as needed to adapt to different material processing requirements, so as to achieve fine crushing, depolymerization, and pulverization of different materials. For example, if finer crushed materials are required finally, the distance between two adjacent first striking rods 4 or two adjacent second striking rods 5 can be made smaller to make the materials strike and collide repeatedly, and fine materials of 0 - 5 mm can be produced, or fine powder below 75 μm can be produced alone. On the contrary, if coarser crushed materials are required finally, the distance between two adjacent first striking rods 4 or second striking rods 5 can be made larger, thus adapting to the processing requirements of products of various finenesses. Moreover, the materials that can be processed include dry, wet, and plastic materials, and there are many types of materials that can be processed.

[0033] On the second disc body where the second ends of the first striking rods 4 are located on the same side, a second rotating groove for the circumferential rotation of each first striking rod 4 is provided. On the first disc body where the second ends of the second striking rods 5 are located on the same side, a first rotating groove for the circumferential rotation of each second striking rod 5 is provided. The first rotating groove and the second rotating groove are arranged opposite to each other front and back. Specifically, the rear ends of the second striking rods 5 on each second striking circle are locked on the front side surface of the rear second disc body 32. The front second disc body 31 has a plurality of front ring bodies 311. The distance between two adjacent front ring bodies 311 is the second rotating groove. Each front ring body 311 is arranged corresponding to each second striking circle and is located behind the front first disc body 21. The front first disc body 21 is in close fit with the front ring body 311. The front ends of the second striking rods 5 on each second striking circle are locked on the front ring body 311 corresponding to the second striking circle. The front ends of the first striking rods 4 on each first striking circle are locked on the rear side surface of the front first disc body 21. The rear first disc body 22 has a plurality of rear ring bodies 221. The distance between two adjacent rear ring bodies 221 is the first rotating groove. Each rear ring body 221 is arranged corresponding to each first striking circle and is located in front of the rear second disc body 32. And the rear second disc body 32 is in close fit with the rear ring body 221. The rear ends of the first striking rods 4 on each first striking circle are locked on the rear ring body 221 corresponding to the first striking circle. Taking one circle of the front ring body 331 and the rear ring body 221 as an example, the positions of the rear ring body 221 and the front ring body 311 are not on the same side and are staggered inside and outside. That is, when the rear ring body 221 is rotatably installed on the front side, the front ring body 311 is rotatably installed on the rear side. The outer diameter of the front ring body 31 is smaller than the outer diameter of the rear ring body 221. During application, the rear second disc body 32, the second striking rods 5 and the front ring body 311 rotate simultaneously. The front first disc body 21, the first striking rods 4 and the rear ring body 221 rotate simultaneously. Driving the rear second disc body 32 to rotate drives the second striking rods 5 to rotate and also drives the front ring body 331 to rotate against the front second disc body 21. The front first disc body 21 rotates, driving the first striking rods 4 to rotate and also driving the rear ring body 221 to rotate against the rear second disc body 32, thereby realizing the staggered rotation between each first striking circle and each second striking circle.

[0034] The rotation driving device has a first driving device and a second driving device; among the four disks, the disk at the frontmost side is one of the second disks. The first driving device is located outside the front side of the housing 1, and the output end of the first driving device extends into the housing 1 and is drivingly connected to the second disk at the front side. The second driving device is located outside the rear side of the housing 1, and the output end of the second driving device sequentially passes through the exposed window of the first disk at the rear side and the second disk at the rear side and is drivingly connected to the first disk at the front side; alternatively, among the four disks, the disk at the frontmost side is one of the first disks. The first driving device is located outside the rear side of the housing 1, and the output end of the first driving device extends into the housing 1 and is drivingly connected to the second disk at the rear side. The second driving device is located outside the front side of the housing 1, and the output end of the second driving device sequentially passes through the first disk at the front side and the second disk at the front side and is drivingly connected to the first disk at the rear side; specifically, taking the first driving device being located at the rear side of the housing 1 as an example, the first driving device has a rear rotating shaft 61 rotatably mounted on the rear side surface of the housing 1 and a first driving motor 62 located outside the left side rear of the housing 1. The first driving motor 62 is horizontally arranged in the front-rear direction. The rear rotating shaft 61 extends in the front-rear direction. The output shaft of the first driving motor 62 faces rearward and is drivingly connected to the rear end of the rear rotating shaft 61, and the front end of the rear rotating shaft 61 is connected to the rear second disk 32, that is, the output end of the first driving motor 62 is horizontally parallel to the rear rotating shaft 62. A first driven wheel 63 is sleeved on the rear end of the rear rotating shaft. The first driving wheel and the second driven wheel are drivingly connected by a first transmission belt; the second driving device has a front rotating shaft 71 rotatably mounted on the front side surface of the housing 1 and a second driving motor 72 located outside the right side front of the housing 1. The second driving motor 72 is horizontally arranged in the front-rear direction. The front rotating shaft 71 extends in the front-rear direction. The output shaft of the second driving motor 72 faces forward and is drivingly connected to the front end of the front rotating shaft 71.

A second driven wheel 73 is sleeved on the front end of the front rotating shaft 71. The second driving wheel and the second driven wheel are drivingly connected by a second transmission belt; during application, the first driving motor 61 is driven to rotate. Under the action of the first driving wheel, the first driven wheel and the first transmission belt, the first driving motor 61 drives the rear rotating shaft 61 to rotate, thereby driving the rear second disk 32 to rotate. Under the connection of the innermost second hitting ring, the front second disk 31 is driven to rotate, and at the same time, other second hitting rings are driven to rotate; similarly, the second driving motor 72 is driven to rotate. Under the action of the second driving wheel, the second driven wheel and the second transmission belt, the second driving motor 72 drives the front rotating shaft 71 to rotate, thereby driving the two first disks to rotate, and further driving the first hitting ring to rotate;Meanwhile, the front rotating shaft 71 extends into the range of the innermost first striking circle. When the material falls into the range of the first striking circle, under the high-speed rotation of the front rotating shaft 71, the material is thrown out at high speed onto each first striking rod 4 of the first striking circle.;

[0035] The feed inlet 100 is within the range between the output end of the second driving device and the first striking circle; specifically, the front first disc body 21 is tightly fitted against the front inner side wall of the housing 1. Through holes penetrating through the front and back are provided in the central area of the front first disc body 21 and on the front side surface of the housing 1. A material guiding hopper extending obliquely upward for guiding the material into the housing 1 is provided on the front side surface of the housing 1. The two through holes are within the range of the material guiding hopper, and the material guiding hopper and the two through holes form the feed inlet 100. The through hole in the front first disc body 21 is located between the transmission shaft 9 and the striking circle body structure; in application, the material enters the range of the first striking circle from the feed inlet 100. Under the action of the high-speed rotation of the front rotating shaft 71, the material collides with the first striking rods 4 of the first striking circle, and then the rotation of the first striking circle is used to throw the material out at high speed into the range of the second striking circle.

[0036] A multifunctional crusher of the present invention, during application, since the feeding port 100 directly faces the front rotating shaft 71, when the material enters from the feeding port 100, the material collides with the front rotating shaft 71. At this time, under the driving action of the second driving device, the front rotating shaft 71 and the first striking ring rotate synchronously at high speed. The rotation of the front rotating shaft 71 throws the material falling from the feeding port 100 at high speed, causing the material to collide with the first striking rods 4 on the first striking ring. The high-speed rotation of the first striking ring throws the material inside the first striking ring at high speed and collides with the second striking rods 5 on the second striking ring. Under the action of the first driving device, the rear rotating shaft 61 and the second striking ring rotate synchronously, so that the second striking rods on the second striking ring throw the material inside the second striking ring at high speed onto the inner side wall of the housing 1, and then pass through the feeding gap and finally fall from the falling port 200; if the material needs to be crushed, then control the rotation directions of the front rotating shaft 71 and the rear rotating shaft 61 to be the same, and the crushing of the material can be achieved. If the material needs to be depolymerized, then control the rotation directions of the front rotating shaft 71 and the rear rotating shaft 61 to be opposite, for example, the rotation direction of the front rotating shaft 71 is clockwise and the rotation direction of the rear rotating shaft 61 is counterclockwise, or the rotation direction of the front rotating shaft 71 is counterclockwise and the rotation direction of the rear rotating shaft 61 is clockwise. At this time, the depolymerization treatment of the material formed by different materials can be carried out; moreover, there are several circles of the first striking ring and the second striking ring. The material is thrown from the innermost first striking ring to the range of the second striking ring of the second circle, and then to the range of the first striking ring of the third circle, and so on, and the material is thrown out in turn through each first striking ring and each second striking ring, and finally the material is thrown to the range of the outermost second striking ring. In this way, under continuous impact, the crushing efficiency of the material can be greatly improved; compared with the prior art, by controlling the rotation directions of the output ends of the first driving device and the second driving device, the material is impacted to different degrees within the first striking ring and the second striking ring to achieve the crushing, depolymerization or pulverization treatment of the material. The crushing specifications of the crushed material are more, and the types of materials that can be processed are also more.

[0037] In this new type, preferably, a transmission shaft 9 is provided outside the front rotating shaft 71. The transmission shaft 9 has a front horn section 91 and a rear cylindrical section 92 behind the front horn section 91. The front horn section 91 is a hollow frustum structure that gradually expands from front to rear, and the rear cylindrical section 92 is a cylindrical structure lying horizontally from front to rear. The rear end of the front rotating shaft 71 extends into the housing 1 and is locked together with the front horn section 91, and the rear cylindrical section 92 is locked together with the rear first disc body 22. During application, the front rotating shaft 71 is locked together with the rear first disc body 22 through the transmission shaft 9, enabling the front rotating shaft 71 to be more firmly connected to the rear first disc body 22. Moreover, when the front rotating shaft 71 rotates, the transmission shaft 9 also rotates at high speed, causing the material to be thrown out at high speed by the transmission shaft 9. Since the rear cylindrical section 92 is a frustum structure that gradually expands from front to rear, the direction in which the material is thrown out is relatively dispersed.

[0038] The product form of the present invention is not limited to the illustrations and embodiments in this case. Any person's appropriate changes or modifications with a similar idea should be regarded as not departing from the patent scope of the present invention.
