Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a pulverizer capable of multiple grinding operations. Background Technology

[0002] Currently, in order to save costs and facilitate manufacturing, the hoppers of domestic crushers are made of cast iron or welded from four iron plates. However, when a large amount of material is fed in, the hopper and the crusher are prone to jamming. Therefore, there is an urgent need to design a mechanism to prevent material jamming in the crusher and solve the problem of the crusher easily jamming.

[0003] This utility model was developed based on the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of the prior art and provide a pulverizer that can be ground multiple times and avoids material jamming in the hopper.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A pulverizer capable of multiple grinding includes a frame with a grinding zone. A hopper assembly is connected to the upper end of the frame. The hopper assembly includes a hopper body connected to the upper end of the frame. The hopper body has a feeding space that can communicate with the grinding zone of the frame. The hopper body is connected to a cover that can rotate relative to it. The cover is provided with protruding teeth that can squeeze the material in the feeding space. A pulverizing blade assembly passing through the grinding zone is connected to the frame. A grinding zone is provided below the grinding zone on the frame. A grinding assembly that can pass through the grinding zone is mounted on the frame.

[0007] The cover body is also connected to a number of protrusions that can cut large pieces of material. The protrusions have inclined cutting surfaces and a separation space is formed between two adjacent protrusions.

[0008] The cover is provided with a limiting groove, the hopper body is provided with a stop surface that can abut against the wall of the limiting groove to prevent the hopper body from continuing to rotate, and the hopper body is also provided with a handle.

[0009] The hopper body is also connected to a first rotating motor on one side. The output shaft of the first rotating motor is connected to a connecting shaft that can rotate with the output shaft. The connecting shaft passes through the feeding space and is connected to a spiral cutter.

[0010] The crushing zone is provided with a plurality of first partition plates and second partition plates. Each of the first partition plates is arranged at intervals along the length direction of the crusher on the front side wall of the crushing zone, and each of the second partition plates is arranged at intervals along the length direction of the crusher on the rear side wall of the crushing zone. Each of the second partition plates is located between two adjacent first partition plates, and a positioning space is formed between adjacent first partition plates and second partition plates. Each of the first partition plates and second partition plates is provided with an inclined surface.

[0011] The shredder assembly includes a first rotating shaft and a second rotating shaft connected to the frame and passing through the shredding zone. Shredders are connected to both the first and second rotating shafts. The shredders are arranged in a positioning space, and the shredders on the first rotating shaft and the shredders on the second rotating shaft are offset. The first and second rotating shafts are connected to meshing transmission gears. A drive motor capable of driving the first rotating shaft to rotate is provided on the first rotating shaft or the second rotating shaft.

[0012] The shredder includes a hexagonal blade body with outwardly protruding cutting and pressing blocks on the blade body.

[0013] A housing is connected to the frame at the grinding area. The housing is located below the grinding assembly and has through holes for material to pass through.

[0014] The grinding assembly includes a second rotating motor connected to a frame. A rotating rod extending into the grinding area is connected to the second rotating motor. Multiple grinding blades are connected at intervals on the rotating rod. Each grinding blade includes at least one straight blade and two curved blades. The tail of the straight blade is connected to the tail of the two curved blades. The straight blade and the two curved blades are spaced apart along the outer periphery of the rotating rod.

[0015] The frame is also equipped with a storage hopper, which is located below the outer shell and corresponds to the position of the through hole. The storage hopper is also equipped with a discharge pipe.

[0016] Compared with existing technologies, this utility model has the following advantages: When it is necessary to grind lumpy materials into powder, the original lumpy materials are introduced into the feeding space. However, the rotation speed of the crushing blade assembly needs to be limited according to the required size of the crushing and cutting. If not handled in time, some lumpy materials will get stuck in the hopper body, or some materials will accumulate in the feeding space after agglomeration. At this time, the cover is rotated. When the cover rotates, it will drive the convex teeth to move. The convex teeth will gradually come into contact with the lumpy materials and cut them into smaller pieces, so that these pieces can enter the crushing zone and be crushed and cut by the crushing blade assembly. The powdered material after crushing and cutting enters the grinding zone. The grinding component performs secondary grinding on the powdered material, making the material more uniform and the particles smaller, which is convenient to feed into the mixing tank for mixing and subsequent packaging, making it more convenient to use.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1 to 12 As shown, a pulverizer capable of multiple grinding includes a frame 1 with a grinding zone 11. A hopper assembly 2 is connected to the upper end of the frame 1. The hopper assembly 2 includes a hopper body 21 connected to the upper end of the frame 1. The hopper body 21 has a feeding space 211 that communicates with the grinding zone 11 of the frame 1. A cover 22, which can rotate relative to the hopper body 21, is connected to the hopper body 21. The cover 22 has protruding teeth 221 that can compress the material in the feeding space 211. A pulverizing blade assembly 3 is connected to the frame 1 and passes through the grinding zone 11. A grinding zone 12 is located below the grinding zone 11 on the frame 1. A grinding assembly 4, capable of passing through the grinding zone 12, is mounted on the frame 1. The material fed into the hopper is a chemical material, etc., which can be pulverized into powder.

[0033] When it is necessary to grind lumpy materials into powder, the original lumpy materials are introduced into the feeding space 211. However, the rotation speed of the crushing blade assembly 3 needs to be limited according to the required size of the crushing and cutting. If not handled in time, some lumpy materials will get stuck in the hopper body 21, or some materials will accumulate in the feeding space 211 after agglomeration. At this time, the cover 22 is rotated. When the cover 22 rotates, it will drive the convex teeth 221 to move. The convex teeth 221 gradually come into contact with the lumpy materials and cut these lumpy materials into smaller pieces, so that these pieces can enter the crushing zone 11 and be crushed and cut by the crushing blade assembly 3. After being crushed and cut, the powdered material enters the grinding zone 12. The grinding component 4 performs secondary grinding on the powdered material, making the material more uniform and the particles smaller, which is convenient to feed into the mixing tank for mixing and subsequent packaging, making it more convenient to use.

[0034] The cover 22 is also equipped with multiple protrusions 222 capable of cutting large pieces of material. Each protrusion 222 has an inclined cutting and pressing surface 2221, and a separation space 223 is formed between adjacent protrusions 222. The protrusions 222 are designed to cut large pieces of material into medium-sized pieces, allowing the material to enter the crushing zone 11. The cutting and pressing surface 2221 facilitates insertion into large pieces of material, making the cover 22 rotate more smoothly.

[0035] The cover 22 is provided with a limiting groove 224, and the hopper body 21 is provided with a stop surface 212 that can abut against the groove wall 2241 of the limiting groove 224 to prevent the hopper body 21 from rotating further. The hopper body 21 is also provided with a handle 225. The handle 225 facilitates the user's rotation of the cover 22. The cooperation of the groove wall 2241 and the stop surface 212 can limit the rotation range of the cover 22.

[0036] A first rotary motor 213 is also connected to one side of the hopper body 21. The output shaft 2131 of the first rotary motor 213 is connected to a connecting shaft 214 that can rotate with the output shaft 2131. The connecting shaft 214 passes through the feeding space 211, and a spiral cutter 215 is connected to the connecting shaft 214. When the cutter 215 rotates, it cuts medium-sized block materials into smaller block materials, which facilitates further extrusion and cutting of block materials into powder materials, improving processing efficiency and making it more convenient to use.

[0037] The crushing zone 11 is provided with multiple first partition plates 13 and second partition plates 14. Each first partition plate 13 is spaced apart along the length of the crusher on the front sidewall 111 of the crushing zone 11, and each second partition plate 14 is spaced apart along the length of the crusher on the rear sidewall 112 of the crushing zone 11. Each second partition plate 14 is located between two adjacent first partition plates 13, and a positioning space 15 is formed between adjacent first partition plates 13 and second partition plates 14. Each first partition plate 13 and second partition plate 14 is provided with an inclined surface 16. The staggered arrangement of the multiple first partition plates 13 and second partition plates 14 reduces the cross-sectional area passing through the crushing zone 11, allowing the crushing blade assembly 3 sufficient space to compress and cut lumpy materials into powder. The inclined surface 16 facilitates guiding the lumpy materials towards the crushing blade assembly 3.

[0038] The shredder assembly 3 includes a first rotating shaft 31 and a second rotating shaft 32 connected to the frame 1 and passing through the shredding zone 11. Both the first rotating shaft 31 and the second rotating shaft 32 are connected to shredders 33. The shredders 33 are arranged in the positioning space 15, and the shredders 33 on the first rotating shaft 31 and the shredders 33 on the second rotating shaft 32 are misaligned. The first rotating shaft 31 and the second rotating shaft 32 are connected to mutually meshing transmission gears 34. The first rotating shaft 31 or the second rotating shaft 32 is provided with a drive motor 35 that can drive the first rotating shaft 31 to rotate. When cutting and grinding are required, the drive motor 35 is started. After the drive motor 35 starts, it drives the first rotating shaft 31 to rotate. When the first rotating shaft 31 rotates, the transmission gear 34 on the first rotating shaft 31 drives the transmission gear 34 on the second rotating shaft 32 to rotate. At this time, the first rotating shaft 31 and the second rotating shaft 32 rotate synchronously. When the first rotating shaft 31 and the second rotating shaft 32 rotate, they respectively drive the crushing blade 33 to rotate. When the crushing blade 33 rotates, it squeezes and cuts the lumpy material into powder, which is convenient to use.

[0039] The shredder 33 includes a hexagonal blade body 331, on which an outwardly protruding cutting and pressing block 332 is provided. The cutting and pressing block 332 can compress and cut blocky materials into powder.

[0040] A housing 5 is connected to the frame 1 at the grinding zone 12. The housing 5 is located below the grinding assembly 4 and has a through hole 51 for material to pass through. The through hole 51 can screen out qualified powder materials and leave unqualified materials inside the housing 5.

[0041] The grinding assembly 4 includes a second rotary motor 41 connected to the frame 1. A rotating rod 42 extending into the grinding zone 12 is connected to the second rotary motor 41, and multiple grinding blades 43 are spaced apart on the rotating rod 42. The multiple grinding blades 43 are used for secondary grinding of the powdered material that has passed through the grinding zone 12, resulting in finer powder particles.

[0042] Each of the grinding blades 43 includes at least one straight blade 431 and two curved blades 432. The tail of the straight blade 431 is connected to the tail of the two curved blades 432. The straight blade 431 and the two curved blades 432 are spaced apart along the outer periphery of the rotating rod 42. The curved blades 432 are curved along one side, which can cooperate with the straight blade 431 to further grind the powdery materials passing through the grinding zone 12, resulting in higher efficiency.

[0043] The frame 1 is also equipped with a storage hopper 6, which is located below the outer shell 5 and corresponds to the position of the through hole 51. The storage hopper 6 is equipped with a discharge pipe 61. The storage hopper 6 is used to store powdered materials, which facilitates the input of powdered materials into the mixer for subsequent packaging.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
