Description

Technical Field

[0001] This utility model relates to the field of pulverizers, and in particular to an agricultural crushing and pulverizing machine. Background Technology

[0002] For Panax notoginseng or other Chinese medicinal herbs, it is sometimes necessary to use a grinder to grind them. Common grinders usually grind the herbs directly, which can easily cause the grinder to get stuck. Therefore, crushing can be done before grinding.

[0003] Chinese Patent Publication No. CN211586840U discloses an integrated crushing and grinding device for Panax notoginseng, including a housing, a shell fixedly connected to the bottom of the housing, a guide pipe extending through the top of the shell near one end, a grinding mill inside the shell, a powder outlet pipe extending through the bottom of the side wall of the shell, a feed hopper extending through the top of the housing near the center, a baffle fixedly connected to the inner wall of the top of the housing on one side of the feed hopper's discharge end, and a second guide plate fixedly connected to the inner wall of the top of the housing on the other side of the feed hopper's discharge end. This device, by incorporating a crushing mechanism, a sieve plate, and a screening mechanism, allows the crushed product of the crushing mechanism to enter the sieve plate. Qualified particles pass through the sieve holes into the grinding mechanism, while unqualified particles are returned to the crushing mechanism for further crushing under the action of a scraper and through the second guide plate. This effectively prevents excessive wear or damage to the grinding mill caused by larger Panax notoginseng particles entering the mill.

[0004] However, the above technical solution has the following shortcomings: when using the crushing mechanism to crush materials, crushed materials are easily left in the area between adjacent crushing plates in the crushing mechanism.

[0024] Example 1

[0025] like Figures 1-7 As shown in this embodiment, an agricultural crusher and pulverizer includes a crushing mechanism, a scraper 63, and a pulverizing mechanism. The crushing mechanism first crushes the material, and then the crushed material is fed into the pulverizing mechanism for further pulverizing, preventing the pulverizing mechanism from getting stuck. While the crushing mechanism is crushing the material, the scraper 63 removes any residual material that may be adhering to it, preventing it from affecting the crushing effect.

[0026] The crushing mechanism includes a feeding hopper 1, a mounting cylinder 2, a guide cylinder 3, two sets of crushing components distributed opposite to each other, and a drive assembly that drives the two sets of crushing components to rotate in opposite directions. The feeding hopper 1, mounting cylinder 2, and guide cylinder 3 are connected sequentially from top to bottom, and the guide cylinder 3 has an inclined discharge channel. Material is fed from the feeding hopper 1 and falls into the inner side of the mounting cylinder 2, where it is crushed by the two sets of crushing components. The crushed material is then conveyed through the guide cylinder 3. The crushing components include a rotating shaft 61 rotatably mounted on the mounting cylinder 2, multiple blades 621 and multiple rings 622 mounted on the rotating shaft 61. The rotating shaft 61 is mounted to the mounting cylinder 2 via bearings. The multiple blades 621 and multiple rings 622 are spaced apart and close together, and are all mounted to the rotating shaft 61 by key connection. The distribution orientation of adjacent blades 621 is different. The outer periphery of the blades 621 has multiple evenly distributed hooks 6211, which can effectively hook the material for crushing during rotation, resulting in good crushing effect and less likelihood of material jamming.

[0027] like Figure 1 and Figure 2As shown, the drive assembly includes a reducer 6 mounted on the mounting cylinder 2, a speed-regulating motor 5 connected to the input end of the reducer 6, and two gears respectively mounted on two rotating shafts 61. The two gears are meshed together, and the output end of the reducer 6 is connected to one of the rotating shafts 61. The speed-regulating motor 5 is mounted at the bottom of the reducer 6. A gear cover 28 is provided on the side of the mounting cylinder 2, and the gears are located inside the gear cover 28, which protects the gears. The speed-regulating motor 5 drives one rotating shaft 61 to rotate through the reducer 6. This rotating shaft 61 drives the gear on it to rotate. This gear drives the other rotating shaft 61 to rotate in the opposite direction through the other gear. The blades 621 on the two rotating shafts 61 rotate in opposite directions, which can effectively crush the material. A control box 4 is provided at the bottom of the mounting cylinder 2. The control box 4 is equipped with a speed control switch 41 and a forward / reverse switch 42. The speed control switch 41 is used to adjust the speed of the speed-regulating motor 5, and the forward / reverse switch 42 is used to control the forward and reverse rotation of the speed-regulating motor 5.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, two scrapers 63 are symmetrically arranged inside the mounting cylinder 2. The scrapers 63 are located below the ring 622. Each scraper 63 includes a mounting plate portion 631 and multiple baffle portions 632. The baffle portions 632 extend between two adjacent blades 621. The scraper 63 has a notch 630 through which the blades 621 pass. The baffle portions 632 are used to scrape away residual material, improving the cleanliness and crushing effect of the crushing component. The scrapers 63 do not interfere with the blades 621.

[0029] The grinding mechanism has a feed inlet connected to the bottom of the discharge channel of the guide cylinder 3. The material crushed by the crushing mechanism slides into the grinding mechanism through the discharge channel and is ground into powder. The grinding mechanism includes a cabinet 22, a mounting cover 14 mounted on the cabinet 22, a cover plate 7 mounted on the mounting cover 14, multiple fixed grinding heads 11 mounted on the cover plate 7, a grinding assembly and a screening assembly mounted inside the mounting cover 14, a discharge cylinder 21 connected to the bottom of the mounting cover 14, and a power assembly that drives the grinding assembly to rotate. The cover plate 7 has an opening connected to the discharge channel of the guide cylinder 3. The crushed material is conveyed to the mounting cover 14 through the guide cylinder 3. The grinding assembly is driven to rotate by the power assembly. The grinding assembly and the fixed grinding heads 11 work together to grind the material into powder. The powdered material is thrown to the screening assembly by centrifugal force and screened. The screened powdered material is discharged from the discharge cylinder 21. The cabinet 22 has a rotating door with a slot for insertion. After the door is closed and locked, the slot is located outside the discharge cylinder 21. The size of the slot is larger than the bottom of the discharge cylinder 21 to prevent interference with the opening and closing of the door. Handles are provided on both sides of the cabinet 22 for workers to easily grip and move the machine.

[0030] This embodiment utilizes the scraper 63 to clean residual material from the crushing components, ensuring the crushing effect of the crushing mechanism. Two sets of crushing components rotate in opposite directions, crushing the material fed from the hopper 1. The crushed material falls downwards. Since the crushing components are rotating relative to the scraper 63, the fixed-position scraper 63 can scrape and clean the rotating crushing components, ensuring the crushing effect of the crushing components on the material. This avoids frequent cleaning and maintenance, saves time, and improves processing efficiency.

[0031] Example 2

[0032] like Figures 1-7 As shown in this embodiment, an agricultural crusher and pulverizer is proposed. Compared with Embodiment 1, in this embodiment, a bracket 8 is provided at one end of the cover plate 7. The bracket 8 is rotatably mounted on one side of the mounting cover 14. A screw 12 is rotatably mounted on the mounting cover 14, and a rotating handle 13 is threadedly connected to the screw 12. A limiting plate 9 is provided at the other end of the cover plate 7. The limiting plate 9 has a groove 901 for the screw 12 to extend into. A sealing ring 10 is provided on the inner side of the cover plate 7. The cover plate 7 can be opened outward through the bracket 8, and can also be closed and locked. When the cover plate 7 covers the side of the mounting cover 14, it is sealed by the sealing ring 10. When the screw 12 is turned into the groove 901, the rotating handle 13 is rotated, and the rotating handle 13 screws into the screw 12, pressing against the limiting plate 9 to lock and fix the cover plate 7.

[0033] In this embodiment, the cover plate 7 is opened and closed using a limiting plate 9, a screw 12, and a rotating handle 13, making the operation simple and convenient.

[0034] Example 3

[0035] like Figures 1-7 As shown in this embodiment, an agricultural crusher and pulverizer is proposed. Compared to Embodiment 1, in this embodiment, the screening component includes a screen frame 18 disposed within a mounting cover 14, and an inner screen 19 and an outer screen 20 coaxially disposed on the screen frame 18 from the inside to the outside. The inner screen 19 and the outer screen 20 are closely fitted together. The inner screen 19 has a first screen hole, and the outer screen 20 has a second screen hole, the size of which is smaller than that of the first screen hole. For powder pulverized by the coordinated action of the fixed pulverizing head 11 and the pulverizing component, screening is performed through two layers of screens. After passing through the first screen hole, the powder must also pass through the second screen hole before falling into the discharge cylinder 21. The thickness of the inner screen 19 is greater than that of the outer screen 20 to prevent the inner screen 19 from being damaged by the pulverizing component.

[0036] In this embodiment, the powder is sieved using two layers of screens, which are not easily damaged and have a long service life.

[0037] Example 4

[0038] like Figures 1-7As shown in the figure, the agricultural crushing and pulverizing machine proposed in this embodiment, compared with the first embodiment, the pulverizing component in this embodiment includes a pulverizing disc 15, a plurality of rotating pulverizing heads 16 arranged around the pulverizing disc 15, and a plurality of pulverizing columns 17 arranged on the pulverizing disc 15. After the cover plate 7 covers the side of the mounting cover 14, the fixed pulverizing head 11 is located between the rotating pulverizing head 16 and the pulverizing column 17, and can pulverize the crushed material through the relative rotation between them.

[0039] like Figure 5 and Figure 6 As shown, the power assembly includes a fixed cover 27 on the top of the cabinet 22, a motor 23 inside the cabinet 22, a first pulley 24 at the output end of the motor 23, a mounting shaft rotatably mounted on the fixed cover 27 and the mounting cover 14, a second pulley 25 mounted on the mounting shaft, and a belt 26 fitted onto the first pulley 24 and the second pulley 25. The powder grinding disc 15 is coaxially mounted at one end of the mounting shaft. The motor 23 drives the first pulley 24 to rotate, the first pulley 24 drives the second pulley 25 to rotate via the belt 26, and the second pulley 25 drives the powder grinding disc 15 to rotate via the mounting shaft, thus driving the powder grinding assembly to rotate. The cabinet 22 has ventilation holes on its side to facilitate heat dissipation during motor 23 operation.

[0040] This embodiment utilizes a power component to drive the grinding component to rotate, and the crushed material is ground by the relative motion between the grinding heads, which reduces the likelihood of jamming.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
