Description

Technical Field

[0001] The utility model relates to a plant crushing device, specifically to a plant crusher. Background Art

[0002] The treatment of agricultural and forestry waste has always been an important topic in the research fields of waste treatment and resource recovery. Agricultural and forestry waste is the material with very low value of the main production materials generated in agricultural or forestry production operations, including various types such as rice straw, fruit tree branches, bark, shrubs, etc. The types involved are complex, and the treatment is troublesome. Traditional treatment methods such as discarding, landfilling, and incineration have made agricultural and forestry waste an important factor polluting the environment.

[0003] In recent years, research has found that most agricultural and forestry waste is rich in plant fibers and has certain recycling value in industry, and can be further processed into raw materials for fuel or fertilizer, such as the organic fertilizer industry, mushroom cultivation industry, mechanism charcoal industry, biomass pellet industry, green plant soil industry, etc. At the same time, new problems of agricultural and forestry waste have also emerged in the process of processing into these raw materials. These new application industries all need to first process agricultural and forestry waste into fine particles before using them as raw materials. The main requirements are in two aspects. One is that the energy consumption and cost should be low enough, and the other is that the particle size should be fine enough. Usually, millimeter-sized particles are required, while traditional crushing and grinding equipment is difficult to meet both of the above requirements at the same time.

[0004] There are various types of agricultural and forestry waste, with various situations such as different dry-wet degrees, different hard-soft degrees, and different initial size degrees. Existing crushing equipment cannot be used for general treatment, and at most can only treat one or two of these types. In particular, wet and soft raw materials are difficult to treat, which greatly limits the recycling application of agricultural and forestry waste. For example, traditional crushers can only treat relatively dry and hard materials and cannot treat soft materials. Especially for materials with relatively high moisture content, drying treatment is required first, resulting in high overall energy consumption and low efficiency in the processing process, and the cost of using the product as a raw material for subsequent industries is relatively high and not economical. Another example is that traditional chipper machines can, in addition to treating dry and hard materials, also treat some relatively large, soft, and wet materials to a certain extent. However, the relatively wet materials are easily adhered to the cutter roller after being chopped, and the relatively soft materials are not easy to cut into small pieces. Generally, the main problem of traditional chipper machines is that the particle size of the product is relatively large, only reaching the centimeter level, which cannot meet the particle size requirements of the raw materials for the backend industries. Adding subsequent treatment processes also increases the cost and energy consumption. Content of the Utility Model

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention is based on the improvement of the basic structure of the drum chipper. Through the improvement of the crushing knife roller mechanism in conjunction with the reciprocating scraping screen mechanism and the overall structural design of the additional auxiliary fixed cutter assembly, a cutting and crushing space with better crushing effect is formed, so that larger materials can be stirred in the cutting and crushing space and cut and crushed into particles of the required particle size multiple times, and the materials will not be pressed and aggregated. It has a good crushing effect on softer and wetter raw materials that traditional equipment cannot handle. The present invention has a clever structural design, is easy and reliable to use, has low operating energy consumption, is easy to maintain, and is suitable for application in the crushing of agricultural and forestry waste plants.

[0021] (2) The crushing knife roller mechanism of the present invention is provided with a larger arc groove for passing materials on the roller body, forming a material flow channel, so that the materials after feeding and cutting can move smoothly in the cutting space. In conjunction with the scraper assembly, the particles that meet the particle size requirements can form a certain discharge pressure when passing through the discharge port and discharge them from the screen, which has a certain forced discharge effect, and continues to stir the particles that do not meet the particle size requirements, so that the materials can be further cut and crushed with the rotation of the roller body, achieving a cutting and crushing effect of smaller particles. Moreover, when facing relatively wet materials, it is not easy to cause the wet materials to aggregate and be unable to be further cut and crushed. Combined with the role of the flying knife assembly to raise the edge position and reduce the edge angle, the high-speed rotating flying knife can cut and crush the materials into smaller pieces, thereby achieving a smaller particle size of the output material while keeping the overall energy consumption controllable. It can also improve the discharge efficiency, thereby making it easier to feed smoothly, thereby improving the processing efficiency of the equipment's cutting and crushing.

[0022] (3) The present invention improves the flying cutter assembly, and adopts the structural design of an integrated flying cutter assembly to cleverly set a flying cutter groove at the front end of the flying cutter pressure seat. After the cutting head is installed, the edge line position is raised closer to the edge circle tangent position on the basis of ensuring the strength of the flying cutter assembly, and the cutting angle of the edge is reduced, the cutting is sharper, and the material cut by the cutter head is smaller, which makes it easier to further achieve the target particle size requirements; at the same time, the cutting head is fixed on the flying cutter pressure seat to form an integrated structure, which can also better maintain the strength of the cutting head and is not easy to be damaged during use. In addition, the cutting head is also composed of a plurality of side-by-side cutting head units, each of which is fixedly installed in the flying cutter groove and combined to form an integrated cutting head, which maintains the consistency of the cutting edge and ensures the overall cutting and crushing effect. In addition, when the local cutting edge is damaged, it can be replaced separately. This is very user-friendly for the cutting head of consumable parts and effectively saves the cost of consumables.

[0023] (4) The present utility model design adds an auxiliary fixed cutter assembly, and ingeniously utilizes the position of the upper machine cover to arrange the auxiliary cutter head. It is not only arranged in a staggered manner with the main cutter head, but also combined with the structural design of the crushing cutter roller mechanism, so that the material is more likely to contact each cutter head during the rotation and agitation process, thereby increasing the probability of the material being crushed, further improving the crushing ability, enhancing the overall cutting and crushing effect, and adapting to the crushing of various types of plant raw materials.

[0024] (5) Through the design of the reciprocating scraping and screening mechanism, on the basis of selectively discharging the cut and crushed material using the discharge screen, the surface of the screen is also scraped while the material is being discharged through the screen, effectively avoiding the situation where the material adheres to the screen during the discharge process and reducing the discharge capacity. Especially when dealing with relatively wet and soft materials, the discharge effect is better.

[0025] (6) The reciprocating scraping and screening mechanism of the present utility model also adds a material brushing component for the automatic cleaning function of scraping and screening. It not only avoids the adhesion of the material on the screen, but also avoids the adhesion of the material on the scraping and screening mechanism, and can better achieve the scraping and screening effect, thereby further improving the discharge effect.

[0026] (7) The present utility model also designs a differential crushing mechanism to further shred the material discharged from the screen, further improving the crushing effect of the material. Brief Description of the Drawings

And a lower operation opening for facilitating manual discharging operation and maintenance can also be arranged on the side of the discharge wall plate facing outside the frame, and a lower sealing plate is configured to close it.

[0065] Specifically, the crushing cutter roller mechanism 100 includes a driving main shaft 101 arranged on the cutting and crushing installation position in the frame through a rotating bearing and a bearing seat, a driving flywheel 107 arranged at one end of the driving main shaft and drivingly connected with a power source outside the frame, a roller body 102 sleeved on the driving main shaft and located inside the frame, at least two material passing arc grooves 103 evenly distributed on the surface of the roller body along the circumference, a flying cutter support 104 respectively arranged in each material passing arc groove and having a material passing gap 105, a flying cutter seat 106 arranged on the flying cutter support and matching the width of the roller body, a flying cutter assembly 120 arranged on the flying cutter seat, and a blade scraping assembly 108 arranged on the roller body at an inclined position at the end of the material passing arc groove. Among them, the flying cutter assembly adopts an integrated flying cutter assembly, the cutting edge of the flying cutter assembly faces the head end direction of the material passing arc groove and is as close as possible to the tangent direction of the circular surface 110 where the cutting edge line is located. The cutting edges of the flying cutter assembly respectively match the cutting edges of the main fixed cutter assembly and the auxiliary fixed cutter assembly to cut and crush materials. The other end of the driving main shaft is connected with a transmission mechanism to provide power for the feeding mechanism, the reciprocating scraping and screening mechanism, and the discharging and conveying mechanism.

[0066] The above term "as close as possible" means that under the condition limited by the thickness of the structural component itself, the cutting angle between the cutting edge line and the tangent of the circular surface where the cutting edge line is located is the smallest. Theoretically speaking, when the cutting edge is only a plane, the cutting force is the largest and the cutting effect is the best when it coincides with the tangent of the circular surface. However, the actual cutting tool head has a material structure thickness to ensure the cutting quality of the cutting tool head. In drum cutting, only the outer edge of the cutting tool head can be as close as possible to the circular surface tangent (to avoid the rotating part touching the fixed tool head), which will inevitably result in a cutting angle between the cutting edge line and its circular surface tangent. The size of this cutting angle is affected by various factors such as the overall size of the equipment, the thickness of the cutting tool head (to ensure the strength of the tool head), and the size of the inner and outer surfaces of the cutting edge. It is difficult to measure with a fixed value. Those skilled in the art can adjust this cutting angle to the smallest based on this term and the structure of the present invention. In the art, generally, this cutting angle can reach less than 45°. For some optimized structures, the minimum can be close to 40°. Through the structural design of the flying cutter assembly in the present invention, this angle can be reduced to about 35° or even lower under the condition of meeting the cutting strength of the tool head, which can improve the cutting effect (sharper for cutting the same material) and reduce the size of the cut materials.

[0067] Moreover, the diameter of the circular surface where the end edge of the blade scraping assembly is located is slightly smaller than the diameter of the circular surface where the cutting edge line is located to prevent the blade scraping assembly from touching the main fixed cutter assembly and the auxiliary fixed cutter assembly when the roller body rotates. The blade scraping assembly can not only scrape and stir the internal materials when the roller body rotates, but also discharge the materials meeting the particle size requirements from the screen when the blade scraping assembly passes through the discharge port through the inclined setting, thus ensuring the quality of the produced materials.

[0068] The number of the arc grooves is preferably four, but can also be configured to other numbers of 2-6 according to actual application requirements. Specifically, the arc grooves 103 are generally in the form of arc-shaped grooves, formed by the roller body 102 being recessed inward from the outer circumference. The four arc grooves give the entire roller body a cross-shaped appearance when viewed from the side, making it convenient to install the flying cutter assembly 120 in the cross-shaped recess and the scraper assembly in the cross-shaped protrusion. The arc-shaped groove shape of the feeding arc groove and the feeding gap on the flying knife bracket can make the cut material move in the cutting and crushing space and not accumulate in the groove. The cutting edge position of the flying knife assembly is toward and close to the head end position of the feeding arc groove, so that the cut material can first fall near the head end position of the feeding arc groove, and move along the arc-shaped groove or the feeding gap to the rear end position of the feeding arc groove as the roller body rotates. Thereafter, it is further pressed out of the discharge port or scraped up by the scraper assembly to be disturbed in the cutting and crushing space. At the same time, due to the gravity of the material itself, there is always a tendency to move downward, and the flying knife assembly can also lift up some of the approaching materials in the bottom-to-top movement stage during the rotation process, and then the high-speed rotation of the knife roller structure as a whole causes irregular disturbance of the materials in the cutting and crushing space. When the irregularly moving part of the material moves between the cutting edge of the flying knife assembly and the cutting edge of the fixed cutter head, it is cut and crushed again.

[0069] The scraper assembly 108 is tilted relative to the circular surface of its distal edge, and forms an acute angle with the tangent of the circular surface toward the beginning of the feed arc. The scraper assembly specifically comprises a scraper holder mounted on the roller body and docked with the distal end of the feed arc, and a press scraper fixed to the scraper holder. The press scraper forms an acute angle with the tangent of the circular surface of its distal edge toward the beginning of the feed arc. Preferably, the acute angle is between 30° and 50°, so as to decelerate the material at the screen position of the discharge port and discharge particles that meet the particle size requirements. Furthermore, the distal end of the press scraper is provided with comb teeth 109. These teeth not only increase turbulence during rotation, enhancing the irregular movement of material within the cutting space, but also effectively scrape softer and / or slender materials, such as straw, dead grass, twigs, and the like, and their cuttings, to enhance the processing capability of such materials.

[0070] Specifically, the flying knife assembly 120 adopts an integrated flying knife assembly, which includes a flying knife pressing seat 121 arranged on the flying knife seat in a matching manner, a flying knife groove platform 122 arranged at the front end of the bottom surface of the flying knife pressing seat, and a cutting tool head fixedly arranged in the flying knife groove platform. Among them, the cutting tool head is composed of a plurality of cutting tool head units 123 arranged side by side. Each cutting tool head unit is separately fixed in the flying knife groove platform. After the cutting tool head is arranged in the flying knife groove platform, the bottom surface of the flying knife pressing seat is flat and fits with the surface of the flying knife seat. The front end of the top surface of the flying knife pressing seat is configured as an inclined surface that matches the upper side of the cutting edge of the cutting tool head. The flying knife pressing seat is fixedly connected to the flying knife seat through a plurality of fastening bolts 124 arranged side by side. The bottom of the front end of the flying knife seat is configured as an inclined surface 125. Through the structural cooperation of the above-mentioned flying knife groove platform and the cutting tool head, compared with the existing structure in which the flying knife pressing plate presses the cutting tool head as a whole (such as the knife roller part in Patent No. 201921126960.7 and 201921313351.2), the position of the cutting tool head is generally raised, thereby reducing the angle between the cutting edge center line of the cutting tool head and the tangent of the circular surface, so as to achieve better cutting performance. After the cutting tool head is arranged in the flying knife groove platform, it is first fixed with bolts, and then the flying knife pressing seat is integrally fixed on the flying knife seat. The flying knife pressing seat presses and clamps the cutting tool head on the flying knife seat, fully ensuring the installation stability of the cutting tool head.

[0071] Specifically, a flying knife adjusting mechanism for adjusting the cutting edge feed amount of the flying knife assembly is arranged on the flying knife seat. The flying knife adjusting mechanism includes a flying knife adjusting platform 126 arranged at the rear end of the flying knife seat, a flying knife adjusting hole 127 arranged on the flying knife adjusting platform, a flying knife adjusting bolt (not shown) arranged in the adjusting hole and corresponding to the rear end of the flying knife pressing seat, and a waist-shaped hole arranged on the flying knife pressing seat for the fastening bolt to pass through, wherein the long axis of the waist-shaped hole is along the adjusting direction. When adjustment is required, first loosen the fastening bolt, then rotate the adjusting bolt to move the flying knife pressing seat to the required position, and finally lock the fastening bolt.

[0072] Specifically, the reciprocating scraping and screening mechanism 50 includes a screen fixing frame 52 disposed at the discharge installation position within the frame, a discharge screen 51 disposed on the screen fixing frame and corresponding to the discharge port of the cutting and crushing space, a scraping and screening frame 53 disposed below the discharge screen and arranged in a staggered manner with the screen fixing frame, a scraping and screening bar 54 disposed on the scraping and screening frame and facing the discharge screen and matching the bottom surface of the discharge screen, a reciprocating connecting rod 55 horizontally connected to the scraping and screening frame and having both ends extending out of the side wall of the frame and rollingly connected to the frame, and a reciprocating driving mechanism 520 disposed on the side of the frame and connected to one end of the reciprocating connecting rod. One end of the reciprocating driving mechanism is eccentrically connected to the transmission mechanism and provides reciprocating power for the reciprocating connecting rod, so that the scraping and screening frame performs a horizontal reciprocating movement below the discharge screen to scrape the materials adhered to the bottom surface of the discharge screen. In order to facilitate the stable movement of the reciprocating connecting rod, support rollers 56 are disposed at the corresponding positions of the side wall of the frame. The reciprocating connecting rod can be configured in the form of a square rod, and the reciprocating connecting rod can be rollingly clamped by two pairs of support rollers.

[0073] Specifically, the screen fixing frame 52 includes fixed connecting rods 511 respectively connected to the frame at the front and rear positions of the discharge installation position, a plurality of screen support pieces 512 arranged side by side between the two fixed connecting rods and in an arc shape, and a support piece cross rib 513 connected to the screen support pieces to maintain fixation. The arc of the screen support pieces matches the arc of the discharge screen and is used to form the position of the discharge port of the cutting and crushing space. The scraping and screening frame 53 includes a scraping and screening cross cylinder 514 sleeved and fixed with the reciprocating connecting rod, a plurality of scraping and screening pieces 515 arranged side by side on the scraping and screening cross cylinder and in an arc shape, and scraping and screening end plates 516 connected to both ends of the scraping and screening pieces. The arc of the scraping and screening pieces matches the arc of the discharge screen. The scraping and screening bar is disposed on the scraping and screening pieces and contacts the bottom side of the discharge screen. The movement of the reciprocating connecting rod drives the scraping and screening cross cylinder and the scraping and screening pieces, so that the scraping and screening bar moves on the bottom side of the discharge screen to scrape the materials adhered to the bottom side of the discharge screen. With such a setting, smooth discharge can also be achieved when facing relatively wet materials, and the adhesion of relatively wet material particles on the screen can be avoided.

[0074] Specifically, the reciprocating driving mechanism 520 adopted in this embodiment includes an eccentric connecting rod 521 with one end eccentrically connected to a runner of the transmission mechanism, a connecting rod driving seat 522 hinged to the other end of the eccentric connecting rod, a linear slider 523 disposed on one side of the connecting rod driving seat, a linear guide rail 524 disposed on the side of the frame and matching the linear slider, a driving inclined groove 525 disposed on the connecting rod driving seat, and a reciprocating driving arm 526 with one end clamped in the driving inclined groove and the other end fixedly connected to the reciprocating connecting rod. The driving inclined groove is parallel to the linear guide rail. The eccentric connecting rod can be eccentrically connected to the lower tooth roller transmission wheel, and the power of the lower fixed tooth roller assembly is used for reciprocating driving. Moreover, the reciprocating driving mechanism is not limited to the above structure, and other forms of reciprocating driving mechanism structures can also be adopted, such as a cam mechanism, a direct drive motor type, and other existing implementation methods.

[0075] Further, a material sweeping component 530 for removing materials in the gaps of the scraping and screening frame is provided below the reciprocating scraping and screening mechanism. The material sweeping component includes a material sweeping rotating shaft 531 arranged in the frame through a rotating bearing and a bearing seat, a material sweeping driving wheel 532 arranged at one end of the material sweeping rotating shaft and in transmission connection with a transmission mechanism outside the frame, and a material sweeping rod 533 arranged on the material sweeping rotating shaft and corresponding to the gaps of the scraping and screening frame in the frame. The material sweeping rods are configured in multiple numbers and respectively correspond to different gaps of the scraping and screening frame. The material sweeping driving wheel can be in transmission connection with the lower roller driving wheel on one side to realize the transmission of the material sweeping power. At the same time, the power sources of the material sweeping driving wheel and the reciprocating driving mechanism are usually configured to come from one mechanism. For example, in the foregoing structure, they both come from the lower fixed roller assembly, or can also be configured as other mechanisms to ensure the action matching between the material sweeping component and the scraping and screening frame, that is, when the scraping and screening frame moves, it can just avoid the action of the material sweeping rod, which is convenient for the material sweeping rod to clean the materials at the fixed position of the scraping and screening frame.

[0076] In another embodiment, as Figures 19 to 22 shown, on the basis of the structure of the above plant crusher, a differential crushing mechanism 70 for further shredding the discharged materials is further provided between the reciprocating scraping and screening mechanism and the discharge conveying mechanism, so as to further improve the material crushing effect. The differential crushing mechanism includes a fixed roller assembly 710 and a moving roller assembly 720 arranged in the frame and cooperating with each other. Among them, the fixed roller assembly is directly connected to the frame, and the moving roller assembly is connected to the frame through a gap adjusting component 730. The gap between the moving roller assembly and the fixed roller assembly is adjusted through the gap adjusting component to adapt to the requirements of different target particle sizes. The fixed roller assembly and the moving roller assembly are respectively connected to different transmission mechanisms to realize differential rotation. And the discharge wall plate 65 arranged around the discharge output installation position correspondingly extends to cover the differential crushing mechanism to ensure that the discharged materials will not leak out.

[0077] Specifically, the fixed roll assembly 710 includes a fixed roll rotating shaft 711 disposed in the frame through a rotating bearing and a bearing seat, a fixed roll tooth roll 712 sleeved on the fixed roll rotating shaft and located in the frame, and a fixed roll driving wheel 713 disposed at the end of the fixed roll rotating shaft and located outside the frame. The fixed roll driving wheel is connected to the transmission mechanism through a corresponding transmission chain according to the transmission requirement to receive power. The movable roll assembly 720 includes a movable roll rotating shaft 721 disposed on the gap adjustment assembly through a rotating bearing and a bearing seat, horizontally disposed in the frame and parallel to the fixed roll rotating shaft, a movable roll tooth roll 722 sleeved on the movable roll rotating shaft and located in the frame, and a movable roll driving wheel 723 disposed at the end of the movable roll rotating shaft and located outside the frame. The movable roll driving wheel is connected to the transmission mechanism through a corresponding transmission chain according to the transmission requirement to receive power. The diameters of the movable roll tooth roll and the fixed roll tooth roll are configured differently to achieve differential rotation. Generally, the movable roll tooth roll can be configured with a small diameter, and multiple movable roll assemblies can be configured, such as two movable roll assemblies arranged side by side vertically and both having a gap match with the fixed roll assembly. Further, both the fixed roll tooth roll 712 and the movable roll tooth roll 722 can be configured as a structure in which a plurality of tooth roll units 701 are arranged side by side. The tooth roll units can be configured with roll teeth 702 of corresponding sizes according to the crushing operation requirements to improve the further crushing effect. At the same time, it is also convenient to replace the tooth roll individually after damage, reducing the use cost.

[0078] Specifically, the gap adjustment assembly 730 includes a movable roll adjustment seat 731 fixedly connected to the side wall of the frame, a movable roll adjustment slot hole provided on the movable roll adjustment seat for arranging the movable roll rotating shaft, a movable roll base 732 arranged on the movable roll adjustment seat and slidably clamped with the movable roll adjustment slot hole, movable roll adjustment rods 733 respectively arranged at both ends of the movable roll base along the long axis direction of the movable roll adjustment slot hole and connected to the movable roll adjustment seat, an adjustment stabilizing spring 734 sleeved on the movable roll adjustment rods, a movable roll card slot provided on the side surface of the movable roll base along the long axis direction of the movable roll adjustment slot hole, and a movable roll card block 735 provided on the movable roll adjustment seat and matched with the movable roll card slot. Among them, the movable roll rotating shaft passes through the movable roll adjustment slot hole and is arranged on the movable roll base through a bearing and a bearing seat; the position of the movable roll base in the movable roll adjustment slot hole can be adjusted and changed by a locking nut configured on the movable roll adjustment rod, and the adjusted position of the movable roll base is maintained stable by the adjustment stabilizing spring, thereby realizing the position adjustment of the movable roll assembly, and thus adjusting and adapting the gap between the movable roll assembly and the fixed roll assembly according to the operation requirements.

[0079] The plant crusher set as above can effectively overcome the drawbacks of existing crushing equipment and related equipment in processing plant raw materials such as agricultural and forestry waste, enabling the output material particles to fully meet the industrial raw material usage requirements of the backend industries, and with low overall energy consumption. Specifically, through the verification of prototype trial production, the materials processed by this equipment are all fine particles in millimeters, without powdery materials or over-sized materials, and can be directly used as industrial raw materials for the backend industries. The equipment has low overall energy consumption and high processing efficiency, greatly reducing the cost of plant crushing. More importantly, this equipment has a wide applicability to plant raw materials of agricultural and forestry waste. There is no need to select various types such as rice straw, bamboo, branches, and fruit shells. As long as it is a plant raw material type, regardless of wet or dry, hard or soft, large or small in shape, it can be processed without restrictive requirements, which can effectively expand the supply of industrial raw materials for the backend industries and effectively solve the environmental protection problem of the existing difficult-to-process agricultural and forestry waste.

[0080] In practical applications, the plant crusher can be configured into different model types such as small mobile type and medium and large fixed type according to usage requirements. For the small mobile type, rollers can be installed at the bottom of the frame, or the whole frame can be installed on a towing device for movement. The power source can be configured as a diesel engine for convenient power supply. During use, it can be directly moved to the site for processing agricultural and forestry waste, avoiding the problem of difficult handling of agricultural and forestry waste; for the medium and large fixed type, it can be fixedly installed and used according to the location of the operation plant area, facilitating large-scale raw material production operations, and the power source can be correspondingly configured as an electric motor.

[0081] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention. Any changes made by adopting the design principle of the present invention and non-creative labor on this basis shall fall within the protection scope of the present invention.
