Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an agricultural straw turning and burying machine that combines rotary and shoveling. Background Technology

[0002] A straw burial machine is an agricultural machine used to turn and bury crop straw into the soil. It primarily addresses the issue of straw returning to the field, improving soil structure and increasing soil fertility. Straw burial machines are typically driven by a tractor, using a three-point suspension for traction. During operation, the cutter shaft rotates at high speed, and its cutting blades chop, impact, and crush the straw on the ground, pulverizing it. Simultaneously, the rotation direction of the cutter shaft is opposite to the rotation direction of the machine's wheels, cutting the soil from the bottom to the surface in a reverse direction, turning the straw into the soil, thus achieving stubble removal, straw return to the field, and rotary tillage to break up the soil.

[0003] In the existing straw turning and burying machine operation process, the equipment mainly relies on the high-speed rotation of the crushing shaft to perform preliminary crushing of straw in the field, and uses the airflow generated during the rotation to throw the crushed straw in a designated direction. Then, the straw is returned to the field by the turning and burying action of the plow plate. However, in actual application, due to the influence of factors such as the density of the crushing shaft blades, the cutting angle of the blades, the moisture content of the straw, and the difference in straw types, the straw is often difficult to be fully crushed. Some straw still exists in the form of long fiber segments or incompletely cut forms. Such insufficiently crushed straw not only causes problems such as wrapping around the plow body and blocking the discharge port of the equipment during the turning and burying stage, reducing the smoothness and efficiency of the turning and burying operation, but also seriously affects the subsequent decomposition rate in the soil due to the uneven distribution of straw in the soil and insufficient contact area with the soil. This leads to a significant decrease in the efficiency of straw conversion into organic fertilizer, making it impossible to quickly replenish the soil with organic matter and achieve the expected soil improvement and fertility enhancement effects.

[0004] Therefore, a new type of agricultural straw turning and burying machine that combines rotary and shoveling is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an agricultural straw turning and burying machine that combines rotary and shoveling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary-spinning combined agricultural straw turning and burying machine includes a casing and a transfer box mounted on the casing. A crushing shaft adapted to the transfer box is installed on the inner side of the casing. Several plow plates arranged in a linear array are fixedly installed on the inner wall of the casing away from the crushing shaft. Two crushing boxes are symmetrically fixedly installed on the inner wall of the casing between the crushing shaft and the plow plates. Several crushing shafts arranged in a linear array are rotatably mounted on the top surface of one crushing box near the crushing shaft. Several evenly distributed crushing blades are fixedly installed on the outer wall of the crushing shaft. A linkage assembly is provided on the inner side of both crushing boxes. A screening assembly is provided on both crushing boxes. Several sets of material feeding assemblies arranged in a linear array are provided on the bottom surface of the crushing box near the crushing shaft.

[0008] As a preferred embodiment of the present invention, a connecting frame for connecting to the drive device is fixedly installed on the top surface of the housing.

[0009] As a preferred embodiment of the present invention, a guide platform is fixedly installed on the top surface of a crushing box near the crushing shaft, a guide plate 1 adapted to the guide platform and the crushing shaft is fixedly installed on the inner wall of the housing, and a guide plate 2 used in conjunction with the guide plate 1 is fixedly installed on the side of the crushing box.

[0010] As a preferred embodiment of the present invention, the linkage assembly includes two shafts symmetrically and rotatably mounted on the inner wall of the crushing box, a drive roller is fixedly mounted between the opposite ends of the two shafts, a drive bevel gear is fixedly fitted on the outer wall of one shaft near the inner side of the crushing box, a support rod is rotatably mounted on the inner top surface of the crushing box, and a driven bevel gear that meshes with the drive bevel gear is fixedly mounted at the bottom end of the support rod.

[0011] As a preferred embodiment of the present invention, the bottom ends of several crushing shafts are connected to each other, the support rod is connected to the bottom end of one of the crushing shafts, and the shaft rod is connected to the crushing shaft via driven wheels and synchronous belts. The side of the housing is provided with a protective shell corresponding to the driven wheels and synchronous belts.

[0012] As a preferred embodiment of the present invention, the screening assembly includes a baffle plate that runs through the side of the crushing box, a guide frame that is slidably connected to the baffle plate is fixedly installed on the inner bottom surface of the crushing box, a pull plate is fixedly installed on one end of the baffle plate located inside the crushing box, and a plurality of levers corresponding to the pull plates are fixedly installed on the outer wall of the drive roller.

[0013] As a preferred embodiment of the present invention, the two baffles are fitted together, and the top surfaces of the two baffles are provided with staggered screen holes.

[0014] As a preferred embodiment of the present invention, the material feeding assembly includes a mounting ring fixedly installed on the bottom surface of the crushing bin. A support rod is rotatably mounted on the inner wall of the mounting ring. A material feeding plate is fixedly mounted on the outer wall of the support rod located between the two crushing bins. A torsion spring is fitted on the outer wall of the support rod, and both ends of the torsion spring are fixedly connected to the mounting ring and the support rod, respectively. A transmission block is fixedly mounted on the end of the support rod. A guide opening is provided on the bottom surface of the crushing bin. A guide block is slidably mounted on the inner wall of the guide opening, and the guide block is fixedly connected to the bottom surface of the pull plate. A top rod is fixedly mounted on the bottom surface of the guide block.

[0015] As a preferred embodiment of the present invention, the cross-sectional shape of the transmission block is a right trapezoid.

[0016] As a preferred embodiment of the present invention, the material feeding plate is initially set at an angle.

[0017] The present invention has the following beneficial effects:

[0018] 1. In this invention, a multi-stage crushing structure with a crushing shaft and a double crushing box is adopted. The crushing shaft first performs preliminary crushing of the straw and guides it to the crushing box with the help of airflow. Then, the crushing shaft drives the linkage component to drive multiple sets of crushing shafts and crushing blades to rotate synchronously, thereby realizing secondary fine crushing of the straw. Compared with traditional single-stage crushing equipment, it solves the problem of insufficient straw crushing, reduces the length of straw fibers, increases the contact area between straw and soil, lays the foundation for subsequent decomposition and conversion into organic fertilizer, and improves the resource utilization efficiency of straw returning to the field.

[0019] 2. In this invention, the reciprocating linkage of the drive roller, L-shaped pull plate and double baffle plate is used to drive the pull plate to slide along the guide frame, so that the baffle plate slides back and forth. This achieves the periodic staggering and overlapping of the screen holes. This design can dynamically screen the crushed straw, allowing only fully crushed straw to fall through the screen holes, avoiding the direct entry of substandard straw into the soil. This prevents large pieces of straw from wrapping around the plow plate and clogging the equipment, ensuring the smoothness of the burial operation, and ensuring that the straw particles entering the soil are uniform in size, thus improving the burial effect and the consistency of straw decomposition.

[0020] 3. In this invention, while the baffle plate slides back and forth, the guide block on the bottom of the pull plate and the transmission block are linked, driving the support rod and the material spreading plate to swing back and forth, so as to evenly spread the screened straw to the ground. This design integrates the crushing, screening and spreading processes, eliminating the need for additional independent spreading equipment, simplifying the operation process and reducing equipment usage costs. At the same time, the uniform distribution of straw can avoid local straw accumulation, so that the straw can be evenly mixed into the soil when the plow is turned over and buried, improving the uniformity of soil organic matter distribution and ensuring the soil improvement and fertility enhancement effects.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1: This example describes the combined rotary and shoveling agricultural straw turning and burying machine disclosed in this embodiment, referring to... Figure 1-8The system includes a housing 11 and a transfer case 12 mounted on the housing 11. A connecting frame 13, connected to a drive unit, is fixedly mounted on the top surface of the housing 11. A crushing shaft 14, adapted to the transfer case 12, is mounted on the inner side of the housing 11. Several plow plates 15 arranged in a linear array are fixedly mounted on the inner wall of the housing 11 away from the crushing shaft 14. Two crushing boxes 21 are symmetrically fixedly mounted on the inner wall of the housing 11 between the crushing shaft 14 and the plow plates 15. A guide platform 24 is fixedly mounted on the top surface of one crushing box 21 near the crushing shaft 14. A guide platform 24 is fixedly mounted on the inner wall of the housing 11. The guide plate 24 and the crushing shaft 14 are fitted with a guide plate 22. The side of the crushing box 21 is fixedly installed with a guide plate 23 that works with the guide plate 22. Several crushing shafts 36 arranged in a linear array are rotatably installed on the top surface of one crushing box 21 near the crushing shaft 14. Several uniformly distributed crushing blades 37 are fixedly installed on the outer wall of the crushing shaft 36. The inner side of both crushing boxes 21 is provided with a linkage component. Both crushing boxes 21 are provided with a screening component. Several sets of feeding components arranged in a linear array are provided on the bottom surface of one crushing box 21 near the crushing shaft 14.

[0032] The implementation principle of this embodiment is as follows: During actual field operations, the operator first securely connects the equipment housing 11 to the tractor's three-point suspension system via a dedicated connecting frame 13. Simultaneously, the tractor's power output shaft is precisely connected to the transfer case 12 on the housing 11 to establish a stable power transmission path. After completing the equipment assembly and power connection, the tractor can be started, driving the housing 11 at a constant speed through the field covered with straw. At this time, the transfer case 12 will rationally distribute the power input from the tractor and transmit it to the housing 11. The crushing shaft 14 of the part is driven to rotate at a preset speed at high speed. The high-speed rotating crushing shaft 14 impacts and cuts the straw on the ground surface through the cutting blades on its surface, completing the initial crushing operation of the straw. At the same time, the high-speed rotation of the crushing shaft 14 will drive the surrounding air to form a directional airflow. This airflow can quickly lift the initially crushed straw fragments and remove them from the ground surface. Then, under the entrainment of the airflow and the guiding and limiting action of the guide plate 1 22 and the guide plate 23, the straw fragments can enter the ground in an orderly manner according to the preset trajectory. The straw fragments enter the processing area between two opposing crushing bins 21. Inside this area, the straw fragments are further driven by a power source. The power output from the crushing shaft 14 is transmitted to a linkage component inside the crushing bin 21. This linkage component synchronously drives multiple sets of crushing shafts 36 and crushing blades 37 fixed to their surfaces to rotate at high speed. The coordinated cutting and kneading action of the multiple sets of crushing blades 37 performs secondary fine crushing of the straw fragments entering the processing area, effectively improving the thoroughness of straw crushing and ensuring that the straw is crushed to meet the requirements for returning it to the field. Particle size; After being fully crushed, the straw fragments will enter the screening area between the two crushing bins 21. Through the screening effect of the screening components, the straw fragments that meet the particle size standard will be screened onto the ground. At the same time, the screened straw fragments will be spread evenly on the field surface by the evenly agitated material feeding components. Finally, the plow plate 15 matched behind the machine casing 11 will plow the evenly spread straw fragments into the deep soil layer during the soil turning operation, so as to achieve full and even burial of straw, laying a solid foundation for subsequent straw decomposition and soil fertility improvement.

[0033] Example 2: Based on Example 1, this example discloses an agricultural straw turning and burying machine that combines rotary and winnowing methods, such as... Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the linkage assembly includes two shafts 31 symmetrically rotatably mounted on the inner wall of the crushing box 21. A drive roller 32 is fixedly mounted between the opposite ends of the two shafts 31. A drive bevel gear 33 is fixedly fitted on the outer wall of one shaft 31 on the inner side of the crushing box 21 near the crushing shaft 14. A support rod 34 is rotatably mounted on the inner top surface of the crushing box 21. A driven bevel gear 35 that meshes with the drive bevel gear 33 is fixedly mounted at the bottom end of the support rod 34. The bottom ends of several crushing shafts 36 are connected to each other, the support rod 34 is connected to the bottom end of one crushing shaft 36, and the shaft 31 is connected to the crushing shaft 14 via driven wheels and synchronous belts. A protective shell 38 corresponding to the driven wheel and synchronous belt is provided on the side of the housing 11.

[0034] The implementation principle of this embodiment is as follows: When the crushing shaft 14 rotates at high speed under the power transmitted by the transfer case 12, its power is transmitted synchronously to the shaft 31 linked with it through the coaxially arranged driven wheel and the synchronous belt wound on the wheel body. The shaft 31 is driven to rotate stably at a speed matching that of the crushing shaft 14. During the rotation of the shaft 31, the drive roller 32 coaxially fixed at its end will rotate synchronously. At the same time, the drive bevel gear 33 mounted at a preset position on the outer wall of the shaft 31 will also rotate with the shaft 31. Since the drive bevel gear 33 and the driven bevel gear 35 are in a perpendicular meshing state, the two... The meshing transmission between them will drive the driven bevel gear 35 and the connected support rod 34 to rotate synchronously, thereby transmitting power to the transmission structure inside the crushing box 21. When the support rod 34 rotates, the driven wheel at its end will transmit power to several crushing shafts 36 inside the crushing box 21 through the synchronous belt, driving multiple sets of crushing shafts 36 and crushing blades 37 fixed on the shaft to rotate synchronously at high speed. By utilizing the synergistic cutting and kneading action of multiple sets of crushing blades 37, the straw crushed material guided by the guide plate into the space between the two crushing boxes 21 is subjected to secondary fine crushing, thereby improving the fullness of straw crushing.

[0035] Example 3: Based on Example 1, this example discloses an agricultural straw turning and burying machine that combines rotary and winnowing methods, such as... Figure 5 and Figure 6 As shown, the screening assembly includes a baffle plate 41 that runs through the side of the crushing box 21. The two baffle plates 41 are fitted together, and the top surfaces of the two baffle plates 41 are provided with staggered screen holes 42. A guide frame 43 that is slidably connected to the baffle plate 41 is fixedly installed on the inner bottom surface of the crushing box 21. A pull plate 44 is fixedly installed at one end of the baffle plate 41 located inside the crushing box 21. Several lever plates 45 corresponding to the pull plate 44 are fixedly installed on the outer wall of the drive roller 32.

[0036] The implementation principle of this embodiment is as follows: When the shaft 31 rotates stably under the power drive of the crushing shaft 14, the drive roller 32 coaxially connected to its end will rotate synchronously. The baffle plate 45 fixed at a preset position on the outer wall of the drive roller 32 will also rotate with the drive roller 32. During the rotation of the baffle plate 45, when it comes into contact with the L-shaped pull plate 44 in the crushing box 21, it will generate a horizontal pulling force on the pull plate 44 by its own rotational thrust. The pull plate 44 is fixedly connected to the baffle plate 41, and the baffle plate 41 is embedded in the slide rail of the guide frame 43. Therefore, under the pulling action of the baffle plate 45, the pull plate 44 will drive the baffle plate 41 to slide smoothly along the preset trajectory of the guide frame 43. When the baffle plate 45 rotates with the drive roller 32 to the position where it is separated from the pull plate 44, the pull plate 44 and baffle 41 will automatically return to their initial positions under the action of the reset component, thereby forming a continuous reciprocating drive for the two baffles 41 between the two crushing boxes 21. During the reciprocating sliding process of the two baffles 41, the screen holes 42 in their initial state are completely staggered. At this time, the screen holes 42 are in a closed state, which can temporarily store the crushed straw. As the baffles 41 slide along the guide frame 43 to the preset stroke position, the screen holes 42 on the two baffles 41 will gradually align until they completely overlap. At this time, the screen holes 42 are in a fully open state. The crushed straw with the required particle size can fall smoothly into the lower area through the overlapping screen holes 42, while the straw with an excessively large particle size that is not fully crushed will be trapped above the baffles 41, thereby achieving precise screening of the crushed straw.

[0037] Example 4: Based on Example 1, this example discloses an agricultural straw turning and burying machine that combines rotary and winnowing methods, such as... Figure 7 and Figure 8 As shown, the material feeding assembly includes a mounting ring 51 fixedly installed on the bottom surface of the crushing bin 21. A support rod 52 is rotatably installed on the inner wall of the mounting ring 51. A feeding plate 53 is fixedly installed on the outer wall of the support rod 52 located between the two crushing bins 21. The feeding plate 53 is initially inclined. A torsion spring 54 is fitted on the outer wall of the support rod 52, and the two ends of the torsion spring 54 are fixedly connected to the mounting ring 51 and the support rod 52 respectively. A transmission block 55 is fixedly installed at the end of the support rod 52. The cross-sectional shape of the transmission block 55 is a right trapezoid. A guide opening 56 is opened on the bottom surface of the crushing bin 21. A guide block 57 is slidably installed on the inner wall of the guide opening 56, and the guide block 57 is fixedly connected to the bottom surface of the pull plate 44. A top rod 58 is fixedly installed on the bottom surface of the guide block 57.

[0038] The implementation principle of this embodiment is as follows: When the push plate 45 rotates with the drive roller 32 and pushes the L-shaped pull plate 44, the guide block 57 integrally formed on the bottom surface of the pull plate 44 will slide along the preset guide opening 56 to ensure the stability of the pull plate 44 when it drives the baffle plate 41 to slide; as the guide block 57 slides, the top rod 58 fixed vertically on its bottom surface will gradually contact the transmission block 55 below. The pushing force continuously applied by the top rod 58 acts on the transmission block 55. Since the transmission block 55 adopts an inclined cross-section design, the pushing force will be converted into the torque that drives the support rod 52 to rotate, so that the support rod 52 rotates synchronously around the inner wall rotation axis of the mounting ring 51, and the push plate 53 fixedly connected to the end of the support rod 52 will also move accordingly between the two crushing boxes 21. The area swings; when the lever plate 45 rotates to separate from the pull plate 44, the torsion spring 54 at the connection between the mounting ring 51 and the support rod 52 will release the preload, driving the support rod 52 to rotate in the opposite direction to reset. The reverse rotation of the support rod 52 will drive the transmission block 55 to move synchronously. The transmission block 55 pushes the top rod 58 in the opposite direction through the inclined section, causing the guide block 57 to slide in the opposite direction along the guide opening 56, thereby pulling the pull plate 44 and the baffle plate 41 back to the initial position. This ensures the continuity of the reciprocating sliding of the baffle plate 41 to achieve stable screening, and the reciprocating rotation of the support rod 52 drives the lever plate 53 to swing continuously, evenly spreading the straw fragments that fall after screening to the field surface, avoiding local accumulation, and providing favorable conditions for the uniform plowing and burying of the plow plate 15 in the future.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
