Technical Field

[0001] The invention relates to the technical field of straw pulverization, and in particular to a straw tearing, grinding and pulverizing machine and a use method thereof. Background Art

[0002] When using straw to prepare biomass raw materials, crushing the straw is a key pretreatment step. The main reasons are as follows: 1. Increase the reaction contact area: After crushing, the surface area of ​​the straw increases, which is convenient for full contact with the catalyst or microorganisms during pyrolysis, gasification or fermentation, thereby improving the reaction efficiency. 2. Improve material fluidity: The crushed straw particles are more uniform and have better fluidity, which is convenient for transportation and processing in the reactor or equipment, reducing blockage. 3. Improve conversion efficiency: The crushed straw is more easily decomposed by chemical or biological processes, speeding up the reaction rate and improving the yield and quality of biomass raw materials. 4. Reduce energy consumption: The crushed straw particles are smaller, and the energy required for subsequent processing (such as drying and compression) is reduced, reducing overall energy consumption. 5. Facilitate mixing and uniform processing: The crushed straw is easier to mix evenly with other raw materials, ensuring consistent reaction conditions and improving product quality. 6. Adapt to equipment requirements: Many biomass processing equipment has requirements for the particle size of the raw materials, and the crushed straw is more in line with the feed standards of these equipment. 7. Reduce the generation of by-products: The crushed straw is easier to react completely during pyrolysis or gasification, reducing the generation of by-products such as tar and improving product purity;

[0003] For example, the prior art patent publication number is CN114097442A, which is entitled: A patent for a corn stalk fertilizer pulverizer. The patent mainly includes an automatic feeding device, a feeding anti-return device and a cutting device, and the stalks are cut and crushed by a transverse blade and a longitudinal blade. The main advantage of the patent is that it can realize automatic feeding, and the stalks are not easy to exit from the feeding port of the pulverizing device, and the length of the stalk crushing can be controlled according to needs;

[0004] The problems with the prior art are: the crushing is achieved through two cuts: horizontal slicing by the cutting shaft and longitudinal cutting by the cutting knife. The cutting process is mainly based on mechanical impact force, which can easily lead to a large amount of powder when the straw fibers are broken. The mechanical cutting action of the cutting blade and the cutting knife lacks the ability to continuously guide the material, and the fragments are easily retained in the cutting area, thus easily causing blockage. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] The present invention provides a straw tearing, cutting, grinding and pulverizing machine and a method for using the same, which can solve the problems in the prior art.

[0007] The cutting process is mainly mechanical impact force, which easily leads to a large amount of powder when the straw fiber breaks. The mechanical cutting action of the cutting blade and the cutter lacks the ability to continuously guide the material, and the fragments are easily retained in the cutting area, thus easily causing blockage. The specific solution is as follows:

[0008] In one aspect, the present invention provides a straw tearing, grinding and pulverizing machine, comprising:

[0009] A crushing component for crushing the straw;

[0010] The conveying component delivers the straw to the crushing component in a directional manner;

[0011] The crushing components include:

[0012] The tearing blade tears the straw in a first direction, and a lower pressing seat is arranged on the upper part thereof;

[0013] The tearing and grinding member is used to tear and cut the straw in the second direction, and a tearing and grinding block is arranged at the lower part thereof, and the second direction and the first direction are perpendicular to each other;

[0014] Among them, the conveying component first conveys the straw to the lower pressing seat, the lower pressing seat and the tearing blade respectively flatten and cut the straw, and then the straw is further moved to the tearing and grinding part, and the tearing and grinding block further crushes the straw.

[0015] Preferably, there are at least two tearing blades which are slidably mounted on the bottom of the lower pressing seat, and a coupling component is provided between the ends of two adjacent tearing blades and the conveying assembly. When the tearing blades are close to the straw, the coupling component causes the adjacent tearing blades to generate shear force.

[0016] Preferably, the crushing assembly further comprises:

[0017] The support member is arranged between the lower pressing seat and the tearing and grinding member, is slidably connected to the lower pressing seat, and has a vertical relative displacement space between the support member and the lower pressing seat;

[0018] The tearing and abrasive member is slidably connected to the supporting member and there is a lateral displacement space between the two.

[0019] Preferably, the conveying assembly includes a conveyor belt and drive rollers coupled at both ends thereof, and a support block is arranged in the middle of the conveyor belt. The top of the support block is in close contact with the upper inner wall of the conveyor belt. When the bottom end of the support member abuts against the top end of the conveyor belt, it can interact with the support block to clamp the conveyor belt, causing the drive rollers to idle and the conveyor belt to be stationary.

[0020] Preferably, baffles are provided at both ends of the conveying assembly, and a limiting plate for controlling the straw at a fixed height is provided on the upper part of the conveying assembly.

[0021] Preferably, the crushing assembly further comprises:

[0022] The screen plate is arranged below the tearing and grinding element, and the straw after being horizontally torn and ground by the tearing and grinding element falls onto the screen plate;

[0023] The sieve holes on the sieve plate filter the fine powder in the shredded and ground straw.

[0024] Preferably, the crushing assembly further comprises:

[0025] A driving rod, both ends of which move synchronously with the supporting member through the connecting arm and rotate around the end of the connecting arm;

[0026] There are a plurality of paddles distributed on the outer wall of the driving rod and rotating synchronously with the driving rod;

[0027] When the support member abuts against the top of the conveying assembly, the paddle on the driving rod corresponds to the discharge position of the straw after being torn and ground by the tearing and grinding member, and is thrown to the storage bin under the centrifugal force generated by the rotation of the paddle and the driving rod.

[0028] Preferably, a plurality of paddles are distributed on the outer wall of the driving rod in a spiral shape, and the sum of the paddle surfaces formed by the plurality of paddles can cover the entire discharge width of the straw.

[0029] Preferably, the crushing assembly further comprises:

[0030] Transmission components are arranged at both ends of the lower pressing seat;

[0031] The rack is fixed to the lower pressing seat;

[0032] The gear and the screw rod move up and down synchronously with the support member through the support frame and are rotationally connected to the end of the support frame;

[0033] The screw is threadedly connected to the tearing and grinding piece. When the rack moves downward along with the lower pressure seat, the gear and the screw are driven to rotate, so that the tearing and grinding piece and the supporting piece slide relative to each other.

[0034] In another aspect, the present invention provides a method for using a straw tearing, grinding and pulverizing machine, comprising the following steps:

[0035] S1, conveying the straw to the tearing blade area through the conveying component;

[0036] S2, the lower pressing seat cooperates with the tearing blade to complete the flattening and tearing of the straw in the first direction;

[0037] S3, transferring the torn straw to the tearing and grinding area;

[0038] S4, performing tearing in a second direction through the cooperation of the tearing and abrasive element and the tearing and abrasive block, wherein the second direction is orthogonal to the first direction;

[0039] S5. Repeat steps S1-S4 to complete the cross-tearing and crushing of the straw. The tearing and grinding blocks form fine crushing of the straw fibers through the vertical shear force field.

[0040] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0041] 1. The present invention significantly optimizes the particle size distribution of straw crushing through the grading processing mechanism of "tearing → tearing and grinding → screening". The tearing component first cuts the long straw into small segments, avoiding excessive fiber breakage caused by traditional high-speed cutting, and reducing powder generation from the source.

[0042] 2. The linear processing path and the guiding design of the tearing and grinding component of the present invention completely solve the problem of easy blockage of traditional pulverizers due to accumulation of debris in the cutting area. The straw material flows unidirectionally along the conveying component and directly enters the tearing and grinding area after being torn and segmented. The grinding process continuously pushes the fragments forward through the rotating extrusion effect to avoid material retention.

[0043] 3. The tearing and grinding component of the present invention replaces mechanical impact with progressive grinding, which further refines the material and reduces the damage to the fiber structure and the powder ratio. The screening function of the discharge component separates the finely crushed material from the powder to ensure that the finished product is mainly uniform finely crushed particles and avoids agglomeration caused by powder mixing.

[0044] 4. The present invention uses centrifugal force to throw the torn and ground straw material to the storage bin by synchronously rotating the driving rod and the paddle, so that the straw particles can be separated to avoid agglomeration and affect subsequent use.

[0045] 5. The present invention adopts a graded processing strategy to optimize energy utilization efficiency through the division of labor and cooperation between the tearing and grinding components. The tearing component completes the initial segmentation of the straw with lower energy consumption, and the tearing and grinding component replaces the "one-size-fits-all" mode of traditional high-speed cutting with progressive grinding, thereby reducing ineffective energy loss. The material always flows along a linear path during the processing, without the need for repeated transportation or secondary processing, thereby shortening the processing cycle.

[0046] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0065] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0066] Embodiment 1: Figure 1 As shown, the present embodiment provides a straw tearing, grinding and pulverizing machine, comprising a conveying component, a tearing component, a tearing and grinding component and a discharging component, wherein the conveying component conveys the straw to be pulverized, so that the straw raw material is located below the tearing component, and then the tearing component tears the straw raw material, so that the longer straw raw material is torn into a plurality of small segments, and then the plurality of small segments of straw raw material are torn and ground by the tearing and grinding component, so that the straw small segments are further ground to form finely pulverized materials, and finally the finely pulverized straw is screened by the discharging component, and the powder particles generated in the tearing and grinding process are screened to form screened materials and screened materials, and this process is to distinguish the finely pulverized materials from the powdered materials, and to avoid the powdered materials being mixed in the finely pulverized materials;

[0067] The effect achieved by adopting the above straw tearing, cutting and grinding scheme is that the straw material can be gradually processed into fine pieces in a linear moving trajectory, which is obviously different from the crushing box scheme in the prior art and can achieve the advantages of anti-blocking, high crushing efficiency and less powder entrainment;

[0068] There are several important reasons to remove fine powder during the comminution of straw:

[0069] Improve the quality of raw materials:

[0070] Fine powders can easily generate dust in subsequent processing, affecting equipment operation and product quality. Removing them can improve the uniformity and stability of raw materials.

[0071] Reduce equipment wear:

[0072] Fine powder can easily enter the gaps of equipment, increase mechanical wear and shorten equipment life. Removing it can reduce maintenance costs.

[0073] Optimize processing efficiency:

[0074] Fine powders may clog equipment or affect reaction uniformity during pyrolysis, gasification or fermentation processes. Removing them can improve processing efficiency.

[0075] Improved storage and transportation:

[0076] Fine powders are prone to generate dust during storage and transportation, causing losses and environmental pollution. Removing them can reduce these problems.

[0077] Reduce safety risks:

[0078] Fine powders are flammable and explosive, especially in high temperature or high pressure environments, and removing them can reduce safety risks.

[0079] Reduce environmental pollution:

[0080] Fine powders are easily blown away by the wind, causing air pollution. Removing them can reduce the negative impact on the environment.

[0081] Improve product purity:

[0082] In the preparation of biomass raw materials, fine powder may affect the purity of the product, and removing it can improve the product quality.

[0083] The above-mentioned conveying assembly, tearing assembly, tearing and grinding assembly and discharging assembly are described in detail below:

[0084] Conveying components:

[0085] The conveying assembly provided in this embodiment mainly includes a base 101, a conveyor belt 103 and a baffle 102, wherein the base 101 is placed on the ground and can be fixed by bolts or other connection methods when necessary, and a top and a space through both ends are formed in the middle of the base 101, and the conveyor belt 103 is installed in the space, and transmission rollers (not shown in the figure) are respectively arranged at both ends of the conveyor belt 103. The two ends of the two transmission rollers are rotatably connected to the two ends of the base 101, and the two ends of the conveyor belt 103 are coupled and connected to the two transmission rollers. When the transmission roller is driven by the driving source, it can drive the conveyor belt 103 and the other transmission roller to operate synchronously, thereby achieving the effect of conveying straw;

[0086] It should be noted that, in order to remove the impurities that may appear in the straw (the impurities include but are not limited to: straw powder, soil, small stones, etc.), it is possible to open a plurality of through holes on the conveyor belt 103, the inner diameter of the through hole is larger than the diameter of the straw to prevent the straw from falling from the through hole, so that the impurities that may appear in the straw can be filtered to avoid affecting the subsequent processing effect;

[0087] The baffles 102 are fixed to both ends of the base 101 by bolts or welding, so that the conveyor belt 103 can protect both ends of the straw during the process of conveying the straw to prevent the straw from falling from both ends of the conveyor belt 103.

[0088] It should be noted that in addition to the above-mentioned method, the conveying component of this embodiment can use other mechanical or manual methods to replace it, as long as the straw can be moved to the flat workstation at the bottom of the tearing component and the grinding component, such as: chain conveyor, screw conveyor, palletizer, etc.

[0089] Tearing components:

[0090] like Figure 2 , Figure 3 As shown, the tearing assembly provided in this embodiment includes a lower pressing seat 201 and a tearing blade 216, wherein the lower pressing seat 201 can move up and down under the drive of a linear drive device, and the linear drive device can specifically be: a hydraulic rod 203, a pneumatic rod, an electric telescopic rod, or other equivalent methods, and a fixing frame (such as Figure 1 As shown), the telescopic end of the linear drive device is fixed to the top of the lower press seat 201, and the top fixed end of the linear drive device is fixed to the top of the fixed frame, thereby providing stable support for the linear drive device, and the bottom end of the linear drive device can be fixed to the side of the base 101 by bolts or welding; wherein the lower press seat 201 is arranged above the output end of the conveying assembly, and when the lower press seat 201 moves downward and the tearing blade 216 approaches the conveyor belt 103 (that is, in contact with the straw material), the tearing blade 216 can produce reciprocating movement along its own blade direction, thereby tearing the straw material and cutting the straw material into a plurality of small segments, and the tearing blade 216 has at least two, and the two adjacent tearing blades 216 move in opposite directions when synchronously, and the length of the several small segments formed by the cutting of the straw material depends on the distance between the blades of the two adjacent tearing blades 216;

[0091] like Figure 4 , Figure 5As shown, in order to achieve the reciprocating motion effect of the tearing blade 216, the tearing assembly provided in this embodiment also includes an inclined block 217. Correspondingly, an inclined surface 218 is provided at one end of the tearing blade 216. The inclined surfaces 218 on two adjacent tearing blades 216 are respectively located at the two ends of the tearing blade 216. For this reason, the inclined blocks 217 corresponding to the inclined surfaces 218 are also respectively located at the two ends of the adjacent tearing blades 216. The inclined block 217 is fixed to the inner wall of the base 101, and when the lower pressing seat 201 is at the upper end, there is still a gap between the inclined surface 218 and the inclined block 217. Only when the tearing blade 216 at the bottom of the lower pressing seat 201 contacts the straw raw material, the inclined surface 218 abuts against the inclined block 217.

[0092] According to the above scheme, when the lower pressing seat 201 moves downward and the tearing blade 216 contacts the upper end of the straw material, the inclined surfaces 218 at both ends of the tearing blade 216 abut against the inclined block 217. At this time, the lower pressing seat 201 continues to press downward, so that the tearing blade 216 moves toward the other end of the inclined block 217. Since there are multiple tearing blades 216, the multiple tearing blades 216 can generate shear force on the straw material, thereby cutting the straw material into multiple small segments.

[0093] It should be noted that, as a feasible connection method between the tearing blade 216 and the lower pressure seat 201, a slide groove and a slider can be respectively set at the top of the tearing blade 216 and the corresponding connecting position of the lower pressure seat 201, wherein the slide groove on the tearing blade 216 is slidably connected to the slider at the bottom of the lower pressure seat 201, and in order to allow the tearing blade 216 to automatically reset after the reciprocating movement is completed, an elastic element is connected between one end of the slide groove and the inner wall of the slider. Through the reset effect of the elastic element, the tearing blade 216 can quickly return to the middle position after the reciprocating movement is completed (the middle position is: the two ends of several tearing blades 216 are in an aligned state, and the whole is in the middle of the lower pressure seat 201). In addition, the above-mentioned tearing blade 216 can be.

[0094] Grinding components:

[0095] like Figure 3 , Figure 6 , Figure 7 As shown, the tearing and grinding assembly provided in this embodiment includes a support member 204 and a tearing and grinding member 208, wherein the support member 204 can move synchronously with a part of the downward pressing stroke of the lower pressing seat 201, and a support rod 214 is connected to the bottom end of the support member 204. When the support member 204 moves downward synchronously with the lower pressing seat 201, so that the bottom end of the support member 204 abuts against the top surface of the conveyor belt 103, the tearing and grinding member 208 can move along the horizontal direction of the conveyor belt 103 toward the discharge direction of the conveyor belt 103;

[0096] Specifically, a limiting hole 209 is provided on the tearing and grinding member 208, and correspondingly, a limiting rod 211 is fixedly connected to one end of the support member 204, wherein the tearing and grinding member 208 is slidably connected to the limiting rod 211 on the support member 204 through the limiting hole 209, and the tearing and grinding member 208 can be made smoother in the process of moving through the limiting rod 211 and the limiting hole 209;

[0097] It should be noted that the above-mentioned tearing and grinding member 208 is specifically configured as follows: when the support rod 214 of the support member 204 is against the top of the conveyor belt 103, the tearing and grinding member 208 can no longer move downward. In this state, there is a gap between the tearing and grinding member 208 and the surface of the conveyor belt 103. When the tearing and grinding member 208 is translated, the straw in the gap can be crushed, thereby achieving the effect of tearing and grinding. Furthermore, a tearing and grinding block 213 is also provided at the bottom of the tearing and grinding member 208. The tearing and grinding block 213 is staggered and distributed at the bottom of the tearing and grinding member 208. The shape of the tearing and grinding block 213 can be: semi-spherical, quadrangular, conical, etc. The tearing and grinding block 213 can also be in the shape of a blade, and the blade is perpendicular to the blade of the tearing blade 216.

[0098] like Figure 7 As shown, since the tearing and abrasive member 208 and the support member 204 may be relatively displaced, in order to avoid motion interference, an open slot 215 is opened at one end of the tearing and abrasive member 208, and the open slot 215 is used to accommodate the support rod 214. When the tearing and abrasive member 208 is away from the support member 204, the support rod 214 can be directly separated from the tearing and abrasive member 208 from one end of the open slot 215, thereby avoiding motion interference.

[0099] Continue reading Figure 7 The support member 204 is configured to be slidably installed in the cavity in the middle of the lower pressing seat 201 as a driving mode of the support member 204. A sliding rod 206 is connected to the top of the support member 204. The sliding rod 206 is slidably connected to the lower pressing seat 201. A first spring 207 is sleeved on the outer wall of the sliding rod 206. The bottom end of the first spring 207 is fixed to the top of the support member 204, and the top end of the first spring 207 is fixed to the top of the lower pressing seat 201. With this scheme, when the lower pressing seat 201 moves downward, the support member 204 moves downward synchronously. When the support rod 214 at the bottom of the support member 204 abuts against the top of the conveyor belt 103, the support member 204 and the tearing and grinding member 208 are stationary, and the lower pressing seat 201 can continue to press down after overcoming the elastic force of the first spring 207. Based on this characteristic, the translation mode of the tearing and grinding member 208 is explained in the following way:

[0100] like Figure 8As shown, as a driving method of the tearing and grinding member 208, racks 220 are arranged at both ends of the lower pressure seat 201, and gears 221 are respectively arranged at both ends of the tearing and grinding member 208, wherein the gear 221 is meshed with the rack 220, and a screw 222 is coaxially connected to the gear 221, wherein the screw 222 is threadedly connected to the bottom of the tearing and grinding member 208, and a support frame 212 is also connected to the end of the support member 204, and a through groove 210 matching the support frame 212 is opened at both ends of the tearing and grinding member 208, wherein the through groove 210 is slidably connected to the support frame 212, and one end of the support frame 212 extends to one side of the tearing and grinding member 208, so that one end of the gear 221 rotates with one end of the support frame 212 The gear 221 is connected to the support member 204, thereby providing a stable support for the gear 221. In other words, the gear 221 and the support member 204 are relatively fixed. According to the above scheme, when the lower pressing seat 201 continues to move downward after the support member 204 abuts against the conveyor belt 103, since the gear 221 and the support member 204 are relatively fixed, the height of the gear 221 does not change, and the rack 220 continues to move downward with the movement of the lower pressing seat 201, thereby causing the gear 221 to rotate. When the gear 221 rotates, the screw 222 also rotates synchronously with it. Since the tearing and grinding member 208 is limited in rotation by the limit rod 211, the tearing and grinding member 208 can only slide, thereby achieving the grinding effect on the straw.

[0101] like Fig. 9 As shown, since the conveyor belt 103 is still running when the tearing blade 216 is tearing the straw, in order to further optimize the solution, a support block 219 is provided in the middle of the conveyor belt 103. When the support rod 214 at the bottom of the support member 204 abuts against the conveyor belt 103, the clamping force generated by the support rod 214 and the support block 219 on the conveyor belt 103 can cause the coupling part of the conveyor belt 103 and the transmission roller to slide, thereby suspending the operation of the conveyor belt 103 and allowing the tearing blade 216 and the tearing and grinding member 208 to fully process the straw.

[0102] It should be noted that if Fig.10 As shown, in the initial stage of preparing the straw raw material, there is no straw raw material under the tearing and grinding member 208 and the support member 204. This process can be understood as not being in the normal processing procedure. After being cut by the tearing blade 216, the cut straw is transported to the bottom of the support member 204 and the tearing and grinding member 208 along with the conveyor belt 103. After that, the lower pressure seat 201 and the tearing blade 216 flatten and cut the straw respectively, and then the straw continues to be moved under the tearing and grinding member 208, and the tearing and grinding member 208 and the tearing and grinding block 213 further crush the straw.

[0103] Discharge components:

[0104] like Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown, the discharge assembly provided in this embodiment includes a sieve plate 301, one end of the sieve plate 301 is hingedly mounted on the side wall of the base 101, wherein a second spring 302 is connected between the bottom of the sieve plate 301 and the base 101, and the function of the sieve plate 301 is: when the straw is crushed by the tearing and grinding member 208, the fine powder produced can be screened through the sieve plate 301 to avoid the fine powder being mixed with the normal straw crushed, which affects the subsequent utilization of the straw crushed; as a driving method of the sieve plate 301: a driving rod 303 is arranged on the sieve plate 301, and driving disks 304 are connected to both ends of the driving rod 303, and a plurality of protrusions 305 are connected to the outer wall of the driving disk 304, wherein when the driving disk 304 rotates, the protrusions 305 can intermittently squeeze the sieve plate 301, so that the sieve plate 301 rotates along the hinge axis between it and the base 101, and under the action of the second spring 302, the sieve plate 301 reciprocates up and down, when the sieve plate When 301 reciprocates up and down, the torn and ground straw on the top can be vibrated up and down, so that the fine powder in the straw is sieved by the sieve plate 301. A connecting arm 309 is connected to one end of the support frame 212, and the end of the driving rod 303 is rotatably connected to the connecting arm 309, and both ends of the connecting position of the driving rod 303 and the connecting arm 309 have raised rings, so as to prevent the driving rod 303 from being separated from the connecting arm 309. A driven bevel gear 306 is also connected to the end of the driving rod 303, and a driving bevel gear 307 meshing with the driven bevel gear 306 is connected to the end of the gear 221; through the above scheme, since the connecting arm 309 is connected to the support frame 212 in an integrally connected manner, when the rack 220 on the lower pressure seat 201 moves downward to drive the gear 221 to rotate, the driven bevel gear 306 and the driving bevel gear 307 will not separate, and the two can always remain in a meshing state on the same horizontal plane;

[0105] like Fig.11As shown, the discharging assembly provided in this embodiment also includes a plurality of paddles 308, which are spirally distributed on the outer wall of the driving rod 303. The paddles 308 crush the driving rod 303 and rotate synchronously, thereby shifting the straw material on the screen plate 301 toward the outlet direction (the outlet direction may be a storage bin). Since the straw material enters the designated area under the swinging state of the paddles 308, the particles of the material can be separated from each other during the splashing process of the material, thereby avoiding the problem that the crusher of the traditional technology easily causes the material to agglomerate; wherein, the shape of the paddle 308 is flat strip as a whole, and has a certain width (the specific width can be freely set according to the actual needs of technicians in this field), and since the plurality of paddles 308 are spirally distributed on the driving rod 303, the material shifting surface composed of the plurality of paddles 308 can cover the entire width direction of the screen plate 301; it should be noted that the paddle 308 may be arc-shaped, and in order to avoid scratching the screen plate 301 by hard materials, the paddle may also have a certain elasticity, and may be made of a plastic sheet or a metal sheet.
