Description

Technical Field

[0001] The present invention relates to the technical field of straw recycling, and particularly relates to a straw recycling device. Background Art

[0002] In agricultural production, due to characteristics such as a humid growth environment, rice straw presents physical characteristics of high humidity and high viscosity. Its texture is more likely to adhere to the surfaces of the blades and sieves of equipment during the pulverization process compared to sorghum straw, forming the phenomenon of rice straw "wrapping and caking". This characteristic causes traditional pulverization equipment to often experience motor overload or even shutdown for cleaning when processing rice straw, severely reducing the pulverization efficiency.

[0003] In addition, rice planting areas often involve complex terrains such as farmlands and wetlands, where problems such as uneven terrain, wet and soft ground often exist. Traditional pulverization equipment mostly adopts a flat base design, which has defects such as a high center of gravity and a small support area. When operating in the above terrains, it is prone to tilt or sink into the ground. The increased vibration of the equipment can also cause component loosening or even failure. At the same time, the high-humidity environment has a strong corrosive effect on the metal components of the equipment base, further shortening the service life of the equipment and restricting the large-scale and efficient operation of rice straw recycling and treatment. Summary of the Invention

[0004] The present invention aims to provide a straw recycling device to solve the technical problems that traditional equipment is prone to adhesion and blockage, low pulverization efficiency when processing high-humidity and high-viscosity rice straw, and poor stability and easy tilting and rusting of the equipment in complex terrains.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A straw recycling device includes a base, a chassis, a storage barrel, and a bracket. The base is spherical, the base is connected to the bracket, a motor is connected inside the base, the output shaft of the motor passes through the chassis and is connected to a turntable, multiple blades are provided on the top of the turntable, a cavity is provided inside the chassis, the cavity is connected to a discharge port, a feeding component is connected inside the cavity, a filter screen is provided on the top of the chassis, the pore diameter of the filter screen gradually decreases from the center to the edge, the bottom of the storage barrel is communicated with the chassis, and a feeding port is provided on the top of the storage barrel.

[0006] Working principle of the present invention: Rice straw enters the storage barrel from the feeding port at the top of the storage barrel, and then falls from the bottom of the storage barrel above the filter screen on the top of the chassis. The motor in the base starts, and its output shaft drives the turntable to rotate. Multiple blades on the top of the turntable rotate at high speed accordingly, cutting and crushing the rice straw above the filter screen. During the rotation of the turntable, the crushed material moves towards the edge of the filter screen under the action of centrifugal force. Since the pore diameter of the filter screen gradually decreases from the center to the edge, the crushed material with a smaller particle size will first pass through the area with a smaller pore diameter in the center of the filter screen and fall into the cavity inside the chassis; while the material with a larger particle size will continue to roll in the storage barrel at the edge of the filter screen and be further crushed by the blades until it can enter the cavity through the area with a smaller pore diameter at the edge of the filter screen. The crushed material entering the cavity is transported to the discharge port by the feeding component in the cavity and finally discharged from the discharge port, completing the recycling and crushing process of rice straw.

[0007] Furthermore, there is a gap between the turntable and the chassis. A smooth plane is provided at the center of the top of the chassis, and the area of the smooth plane is the same as the size of the turntable. Brushes are symmetrically arranged at the bottom of the turntable. Through the arrangement of the brushes, the brushes at the bottom of the turntable synchronously clean the surface of the filter screen during rotation. Combining with the gap design between the smooth plane at the top of the chassis and the turntable, a dynamic self-cleaning system is formed, which can timely remove the blockage of the filter screen holes caused by the residue of highly viscous distiller's grains.

[0008] Furthermore, the bracket is triangular. Each leg of the bracket is connected to the base through a hinge, and an adjustable-height screw is provided at the bottom of the leg. By rotating the screw, the inclination angle of the bracket can be adjusted within the range of 30° - 60°. The hinge connection and screw adjustment function of the triangular bracket enable the device to dynamically adjust the inclination angle according to the ground conditions. Combining with the curved surface design of the spherical base, the support area is expanded, the center of gravity is reduced, and the anti-overturning ability during operation on wet and soft ground is improved.

[0009] Furthermore, the multiple blades are distributed in two annular arrays, namely an inner ring and an outer ring. The length of the inner ring blades is less than that of the outer ring blades, and the inner ring and outer ring blades are arranged with a 30° - 60° offset in the circumferential direction. The offset distribution of the short inner ring blades and the long outer ring blades forms a "three-dimensional cross-cutting area". The inner ring is responsible for crushing the middle fibers of the straw, and the outer ring covers the edge area. The offset angle of 30° - 60° eliminates the cutting blind area and improves the crushing uniformity; at the same time, the different blade lengths and offset layout reduce the probability of straw winding around the blades.

[0010] Furthermore, the base is made of anti-corrosion material. By restricting the material of the base, the overall service life of the device is extended.

[0011] Furthermore, the cutting surface of the blade is inclined. Through the angle setting of the blade, the rice straw can be further contacted and crushed by the blade, and at the same time, the rice straw is prevented from getting stuck in the gap between the blade and the turntable.

[0012] Further, the feeding component is a hair dryer which is arranged inside the base. The output end of the hair dryer is located inside the cavity and is aligned with the discharge port. By arranging the hair dryer, the lightweight straw fragments inside the cavity can be quickly conveyed to the discharge port, and the airflow can disperse the caking tendency of the wet materials, avoiding the accumulation and retention of the fragments inside the cavity.

[0013] Further, the feeding component is a scraper. One side of the scraper is connected to the output shaft of the motor, and the size of the scraper is adapted to the cavity. By arranging the scraper, the highly viscous materials inside the cavity can be forcibly scraped.

[0014] Advantages of the present invention: 1. Aiming at the characteristics of high humidity and high viscosity of rice straw, the design that the aperture of the filter mesh gradually decreases from the center to the edge forms a "graded crushing" mechanism. The fragments with smaller particle sizes can quickly fall through the large-aperture area in the center, avoiding accumulation and blockage. The larger straws are secondarily crushed by the blades at the edge of the turntable until they pass through the small-aperture filter mesh at the edge. Compared with the traditional single-aperture filter mesh, the crushing efficiency is improved, and the particle size requirements of multiple scenarios such as feed and biomass fuel can be flexibly adapted through the aperture gradient; the symmetrically arranged brushes at the bottom of the turntable cooperate with the smooth plane at the top of the chassis to synchronously clean the surface of the filter mesh during the operation of the equipment, timely removing the adhered residues of rice straw, avoiding the shutdown and cleaning problems caused by straw entanglement in traditional equipment, and prolonging the continuous operation time.

[0015] 2. The present invention adopts the combination of a spherical base and a triangular support. The spherical base reduces the center of gravity through the geometric curved surface design. Cooperating with the hinge connection and screw height adjustment function of the triangular support, the support posture can be dynamically adjusted in complex terrains such as waterlogging and muddy ground, expanding the support area and reducing the vibration amplitude, and significantly improving the anti-overturning ability. Compared with the fixed support structure commonly adopted by existing straw processing equipment, the present invention improves the operation stability on wet and soft ground, reduces the risk of component loosening caused by uneven terrain. At the same time, the spherical base is made of anti-corrosion materials, further prolonging the service life of the equipment in high-humidity environments.

[0016] 3. The dual-mode design of the feeding component further enhances the practicability of the equipment: the hair dryer mode uses the airflow to quickly push the fragments inside the cavity, improving the discharge efficiency and avoiding the accumulation and caking of wet materials; the scraper mode forcibly scrapes the viscous materials through the linkage of the motor shaft and the scraper, reducing the risk of blockage. The two modes can be flexibly switched according to the material characteristics, expanding the applicable range of the equipment. Description of the Drawings

[0021] The following is a further detailed description through specific embodiments:

[0022] The reference numerals in the accompanying drawings of the specification include: base 1, chassis 2, cavity 201, scraper 202, storage barrel 3, filter screen 301, smooth plane 302, discharge port 4, bracket 5, turntable 6, blade 601, output shaft 7 of the motor.

[0023] Embodiment 1 is basically as shown in the accompanying Figures 1-3 drawing: A straw recycling device includes a base 1, a chassis 2, a storage barrel 3 and a bracket 5. The base 1 is spherical, made of anti-corrosive material. The base 1 is slidably connected to the bracket 5. The bracket 5 is triangular, and each leg of the bracket 5 is detachably connected to the base 1 through a hinge. The bottom of the leg is provided with a screw for adjusting the height. By rotating the screw, the inclination angle of the bracket 5 can be adjusted within the range of 30° - 60°. A motor is fixedly connected inside the base 1, and the output shaft 7 of the motor penetrates through the chassis 2 and is fixedly connected to the center of a turntable 6. There are nine blades 601 on the top of the turntable 6. The nine blades 601 are divided into two annular arrays of an inner ring and an outer ring. The inner ring has three blades 601, and the outer ring has six blades 601. The length of the inner ring blades 601 is less than that of the outer ring blades 601, and the inner ring and outer ring blades 601 are offset by 30° - 60° in the circumferential direction. The cutting surfaces of the nine blades 601 are all inclined in the outward emission direction starting from the center of the turntable 6. There is a cavity 201 inside the chassis 2. The cavity 201 is fixedly connected to a discharge port 4. A feeding component is connected inside the cavity 201. The feeding component is a blower fixedly arranged inside the base 1. The output end of the blower is fixedly connected inside the cavity 201 through a hose and is aligned with the discharge port 4. There is a smooth plane 302 at the center of the top of the chassis 2. The area of the smooth plane 302 is the same as the size of the turntable 6. There is a gap between the turntable 6 and the chassis 2. Brushes are fixedly and symmetrically arranged at the bottom of the turntable 6. The length of the brushes is the same as the diameter of the chassis 2. A filter screen 301 is fixedly connected between the smooth plane 302 and the top end of the chassis 2. The pore diameter of the filter screen 301 gradually decreases from the center to the edge. The bottom of the storage barrel 3 is communicated with the chassis 2, and the top of the storage barrel 3 is provided with a feeding port.

[0024] Embodiment 2 is as shown in the accompanying Figure 1 and 2, as shown in Figure 4: The feeding component is a scraper 202. One side of the scraper 202 is fixedly connected to the output shaft 7 of the motor, and the size of the scraper 202 is adapted to the cavity 201.

[0025] The specific implementation process is as follows: Install the feeding component according to the material characteristics: If processing highly viscous rice straw, fix one side of the scraper 202 on the motor output shaft and adjust it to fit the inner wall of the cavity 201; if processing relatively dry rice straw, fix the hair dryer in the base 1, and the output end is aligned with the discharge port 4 of the cavity 201 through a hose. Then place the spherical base 1 on the working site, ensure that the ground is flat and free of sharp debris, unfold the triangular support 5 and adjust the inclination angle through the screw at the bottom of the support leg so that the base 1 is kept horizontal, ensure that the support legs of the triangular support 5 are evenly stressed to adapt to the wet and soft ground. Pour the rice straw evenly into the feeding port of the storage barrel 3, and the single feeding amount does not exceed 2 / 3 of the volume of the storage barrel 3. Start the motor, and the turntable 6 drives the inner ring short blades 601 and the outer ring long blades 601 on the turntable 6 to rotate at high speed. The two circles of blades 601 are staggered by 30°-60° to form a "three-dimensional cross-cutting area" to initially cut and edge-cover and crush the straw. The crushed material moves towards the filter screen 301 under the action of centrifugal force. The large aperture in the center of the filter screen 301 allows small-particle-sized crushed materials to fall into the cavity 201 of the chassis 2, and the small apertures at the edge enable the large-particle-sized materials to continue to be secondarily crushed. The brush at the bottom of the turntable 6 synchronously sweeps the surface of the filter screen 301 to prevent blockage; when discharging, the hair dryer mode uses air flow to push the crushed materials and blow and disperse the agglomerates, and the scraper 202 mode forcibly scrapes the highly viscous materials through the linkage of the motor shaft. The crushed materials can be collected as needed for scenarios such as feed or biomass fuel.
