Description

Technical Field

[0001] This invention relates to the field of soybean harvester technology, specifically a highly adaptable soybean harvester. Background Technology

[0002] In the process of large-scale soybean planting and harvesting, soybean harvesters play a crucial role as key agricultural machinery. They can not only significantly improve harvesting efficiency and reduce labor intensity, but also play an important role in ensuring soybean yield and quality. However, traditional soybean harvesters still have some limitations in design, especially in the use and protection mechanism of the cutting blade, which urgently needs to be improved and optimized. First, during actual operation, the cutting blades of soybean harvesters may "bite the soil" or get stuck on hard objects for various reasons. "Biting the soil" usually occurs during the harvester's movement. Due to factors such as undulating terrain, loose and uneven soil, or improper operation, the cutting blades may accidentally touch the ground while cutting crops, causing accelerated wear on the blades or even direct damage. As for getting stuck on hard objects, it may be due to obstacles such as stones or tree roots in the field. When the cutting blades collide with these obstacles during operation, the blades will be subjected to huge resistance at the moment and will not be able to operate normally. When the cutting blade gets stuck in the soil or encounters hard objects, if it is not dealt with promptly and effectively, a series of adverse effects will occur. First, blade wear or damage will directly affect harvesting efficiency and quality, increasing maintenance costs and downtime. Second, the motor may burn out due to overload, further amplifying economic losses. In addition, under extreme conditions, the blade may also suffer serious malfunctions such as twisting or breakage, posing a threat to the safety of operators and equipment. Secondly, most existing soybean harvesters use a fixed design for their cutting blades, meaning the distance between the two cutting blades is determined during manufacturing and cannot be adjusted according to actual operational needs. Although this design is simple in structure, it is clearly insufficient in adaptability and flexibility when facing different varieties of soybean crops, soybean fields with varying growth conditions, or harvesting environments with complex and varied terrain. Summary of the Invention

[0003] The purpose of this invention is to provide a highly adaptable soybean harvester, so as to at least solve the problems in the prior art, such as insufficient adaptability and flexibility due to the non-adjustable spacing of the cutting blades, the cutting blades being prone to "biting" into the soil or getting stuck in hard objects, causing blade damage and motor overload.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a highly adaptable soybean harvester, comprising: a soybean harvester, a divider, and a cutting mechanism, wherein the divider is disposed at the bottom front side of the soybean harvester, and the cutting mechanism is disposed at the bottom end of the divider; The cutting mechanism includes a frame, a support assembly, a cutting blade, an adjustment assembly, and a drive assembly.

The rear end of the first connecting rod is locked to the output end of the first motor via a coupling. The front end of the first connecting rod rotatably extends into the inner cavity of the frame. The rear center of the turntable is located at the front end of the first connecting rod. There are four connecting rods, each with one end rotatably mounted on the left and right sides of the two turntables via pins, and the other end rotatably mounted on the rear center of the four support frames via pins.

[0008] Preferably, the drive assembly includes: a geared disc, a drive rod, a second motor, a second connecting rod, an extrusion groove, a gear, a slot, and a protective component. The outer walls of the geared disc are rotatably mounted in the middle of the inner cavity of the frame via bearings on both the upper and lower sides. The geared disc is located between two cutting blades. There are two drive rods, which are respectively located on the front side of the top end and the rear side of the bottom end of the geared disc. The outer walls of the two drive rods are slidably adapted to the inner cavities of the two drive grooves. The second motor is screwed to the rear side of the bottom end of the inner cavity of the frame. The bottom end of the second connecting rod is locked to the output end of the second motor via a coupling. The outer wall of the second connecting rod has several extrusion grooves equidistantly spaced along the circumference.

The gear meshes with the geared disc. The inner wall of the gear has several slots equidistantly spaced along the circumference. The positions of the slots correspond one-to-one with the positions of the extrusion grooves. The protective component is located in the inner cavity of the extrusion groove.

[0009] Preferably, the protective assembly includes: a screw, an extrusion rod, an extrusion seat, a roller, a spring, and a retaining ball.

[0010] Preferably, the length of the ball extending into the inner cavity of the slot is less than its radius.

[0011] The present invention proposes a highly adaptable soybean harvester, the advantages of which are as follows: 1. This invention uses a first motor to drive a turntable and a linkage system, which in turn moves the support frame and the cutting blades up and down, allowing for flexible adjustment of the cutting blade spacing. This enables the harvester to adapt to different varieties and growth conditions of soybean crops, as well as complex and ever-changing harvesting environments, significantly improving the adaptability and flexibility of the equipment. It avoids low cutting efficiency or blade damage caused by fixed spacing, improves harvesting quality and equipment versatility, and by adjusting the cutting blade spacing to the maximum, it is easy to clean the soybean stalk fiber and other debris remaining between the two cutting blades, thereby reducing the impact of debris accumulation on the next operation, keeping the equipment clean, and improving operating efficiency. 2. When the cutting blade encounters a hard object or "grinds" soil during use, the protective component, through the cooperation of the retaining ball and the spring, causes the second motor to drive the second connecting rod to "idle," avoiding motor overload and thus effectively preventing motor burnout and blade damage. This reduces maintenance costs, improves equipment reliability, and ensures operational safety. 3. This invention significantly improves the adaptability, cutting efficiency, equipment reliability, and maintenance convenience of soybean harvesters through designs such as adjustable cutting blade spacing, overload protection, and convenient cleaning. It effectively solves the problems of easy damage to cutting blades, easy overload of motors, and low operating efficiency existing in the prior art. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-12 This invention provides a highly adaptable soybean harvester technical solution, including: a soybean harvester 1, a divider 2, and a cutting mechanism 3. The soybean harvester 1 is existing technology and will not be described in detail here. As the main body of the overall equipment, the soybean harvester 1 carries the divider, the cutting mechanism, and other functional modules, providing power transmission, walking control, and material collection functions, realizing the fully automated harvesting of soybeans from the field to the on-board storage device. The divider 2 is set at the bottom front side of the soybean harvester 1. The divider 2 is existing technology and will not be described in detail here. The divider 2 is used to accurately separate the soybean plants to be harvested from the unharvested plants, and at the same time guide the plants into the cutting mechanism to avoid missed cutting or repeated cutting. The cutting mechanism 3 is set at the bottom of the divider 2, and the cutting mechanism 3 cuts the soybean stalks.

[0016] As a preferred embodiment, the cutting mechanism 3 further includes: a frame 31, a support assembly, a cutting blade 39, an adjustment assembly, and a drive assembly. The frame 31 is located at the bottom end of the divider 2, serving as the basic load-bearing structure of the cutting mechanism and providing rigid mounting space for the support assembly, cutting blade, adjustment assembly, and drive assembly. The support assembly is located within the cavity of the frame 31 and is used to achieve precise vertical and horizontal displacement of the cutting blade 39. There are two cutting blades 39, positioned on the upper and lower sides of the support assembly, respectively. The blades 39 are located on the upper and lower sides of the inner cavity of the frame 31. The top rear side of the cutting blade 39 has a drive groove 310 that runs through it from top to bottom along the front and back direction. The cutting blade 39 is existing technology and will not be described in detail here. The cutting blade 39 is used for efficient stalk cutting. The adjustment component is located on the rear side of the frame 31. The adjustment component is used to realize the electric adjustment of the spacing between the cutting blades 39. This design supports quick adaptation to differences in soybean varieties before operation and the convenience of cleaning up residues after operation. The drive component is located in the middle of the inner cavity of the frame 31. The drive component is used to form a double blade synchronous reverse cutting. The support assembly includes: a first guide rod 32, a support frame 33, and a second guide rod 38. There are four first guide rods 32, which are arranged in pairs to form two groups. The upper and lower ends of the two groups of first guide rods 32 are respectively located on the upper and lower sides and the left and right ends of the inner cavity of the frame 31. The first guide rods 32 serve as the vertical guide reference for the support frame 33. There are four support frames 33, which are slidably fitted to the upper and lower sides of the outer wall of the two groups of first guide rods 32. The support frame 33 is used to connect the cutting blade 39. There are four second guide rods 38, which are respectively located on the left and right rear ends of the two cutting blades 39. The cross-section of the second guide rod 38 is a regular polygon. The outer walls of the four second guide rods 38 are slidably fitted into the middle of the inner cavity of the four support frames 33. The second guide rods 38 serve as the horizontal guide reference for the cutting blade 39. The adjustment assembly includes: a first motor 34, a first connecting rod 35, a turntable 36, and a connecting rod 37. There are two first motors 34, each screwed to the left and right ends of the rear side of the frame 31. The first motors 34 are existing technology and will not be described in detail here. The first motors 34 convert electrical energy into mechanical energy through their rotational motion, driving subsequent transmission components. They are the power core of the adjustment assembly, ensuring continuous and stable adjustment. The rear end of the first connecting rod 35 is locked to the output end of the first motor 34 via a coupling. The front end of the first connecting rod 35 rotatably extends into the inner cavity of the frame 31. The rear center of the turntable 36 is located at the front end of the first connecting rod 35. The turntable 36 serves as the connecting base for the connecting rod 37, and its rotational motion can drive… The moving link 37 swings or moves accordingly, converting the rotational motion into a complex motion form of the link 37, thereby realizing the adjustment function of the adjustment component on other components. It is a key transmission component in the adjustment process. There are four links 37. One end of the four links 37 is rotatably set on the left and right sides of the two turntables 36 through pins, and the other end of the four links 37 is rotatably set on the rear middle of the four support frames 33 through pins. Driven by the turntables 36, the link 37 converts the rotational motion of the turntables 36 into a pushing, pulling or traction force on the support frames 33 through its own swinging or moving, thereby realizing the adjustment of the position or attitude of the support frames 33. It is a key execution component in the adjustment component that realizes power transmission and motion form conversion, and ultimately acts on the target component. The drive assembly includes: a gear disk 311, drive rods 312, a second motor 313, a second connecting rod 314, an extrusion groove 315, a gear 322, a slot 323, and a protective assembly. The gear disk 311 is rotatably mounted in the center of the inner cavity of the frame 31 via bearings on both its upper and lower outer walls. The gear disk 311 is located between two cutting blades 39. The gear disk 311 serves as the power conversion hub of the drive assembly, driving the cutting blades 39 to achieve reciprocating cutting through rotational motion. There are two drive rods 312, located at the front top and rear bottom of the gear disk 311, respectively. The outer walls of the two drive rods 312 are slidably adapted to the inner cavities of the two drive grooves 310. The drive rods 312 convert the rotational motion of the gear disk 311 into the linear reciprocating motion of the cutting blades 39. The second motor 313 is screwed to the rear bottom of the inner cavity of the frame 31. The second motor 313 is existing technology and will not be described in detail here. The second motor 313 provides the original power for the entire drive system. The bottom end of the second connecting rod 314 is locked to the output end of the second motor 313 by a coupling. The outer wall of the second connecting rod 314 is provided with a plurality of extrusion grooves 315 at equal intervals along the circumference. The top end of the second connecting rod 314 extends rotatably out of the top end of the frame 31. The second connecting rod 314 serves as a power transmission shaft, connecting the second motor 313 and the gear 322. The gear 322 is rotatably sleeved on the outer wall of the second connecting rod 314 through a bearing. The gear 322 meshes with the gear disk 311. The inner wall of the gear 322 is provided with a plurality of slots 323 at equal intervals along the circumference. The positions of the slots 323 correspond one-to-one with the positions of the extrusion grooves 315. The gear 322 is used to transmit the rotational motion of the second motor 313 to the gear disk 311. The protective component is set in the inner cavity of the extrusion groove 315. The protective component is used to prevent the second motor 313 from being overloaded. The protective assembly includes: a screw 316, a pressing rod 317, a pressing seat 318, a roller 319, a spring 320, and a retaining ball 321. The screw 316 is screwed to the top end of the inner cavity of the second connecting rod 314, and the top end of the screw 316 extends beyond the top end of the second connecting rod 314. The screw 316 serves as the core for adjusting the preload of the protective assembly, and the axial displacement of the pressing rod 317 is controlled by rotation. The pressing rod 317 is rotatably mounted on the bottom end of the screw 316 via a bearing. 17 can convert the rotational motion of the screw 316 into a linear extrusion force on the roller 319. The extrusion seat 318 is slidably adapted to be inserted into the inner cavity of the extrusion groove 315. The inner end of the extrusion seat 318 extends slidably into the inner cavity of the second connecting rod 314. The extrusion seat 318 serves as an intermediate force transmission component between the spring 320 and the roller 319, realizing dynamic compensation for elastic preload. The roller 319 is rotatably mounted on the inner end of the extrusion seat 318 via a bearing. The outer wall of the roller 319 and the extrusion... The outer wall of the rod 317 is in contact with the roller 319, which converts the sliding friction of the extrusion rod 317 into rolling friction, reducing transmission loss. The spring 320 is embedded in the inner cavity of the extrusion groove 315, and one end of the spring 320 is engaged with the outer side of the extrusion seat 318. The spring 320 is a rotary spring, which undergoes elastic deformation after being compressed or stretched by external force, and returns to its initial state after the external force is removed. The spring 320 is used to provide a continuous meshing force between the ball 321 and the groove 323, ensuring that the gear 322 and the groove 323 are engaged. The second connecting rod 314 is reliably connected. A part of the ball 321 is slidably embedded in the inner cavity of the compression groove 315, and the other part of the ball 321 is adapted to be inserted into the inner cavity of the corresponding slot 323. The other end of the spring 320 is engaged with the outer wall of the ball 321. The length of the ball 321 extending into the inner cavity of the slot 323 is less than its radius. The ball 321 serves as a key component of the mechanical interlock, enabling the gear 322 and the second connecting rod 314 to be quickly positioned and prevented from loosening.

[0017] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0018] Step 1: During use, adjust the maximum cutting force that the two cutting blades 39 can apply according to factors such as the soybean variety to be harvested and the material of the cutting blades 39. The rotational force generated by rotating the screw 316 can drive the extrusion rod 317 to move up and down. When the extrusion rod 317 moves downward, it can push the extrusion seat 318 into the inner cavity of the extrusion groove 315 and compress the spring 320, increasing the elastic deformation of the spring 320, thereby increasing the extrusion force applied by the spring 320 to the ball 321. Conversely, when the extrusion rod 317 moves upward, the spring 320 can push the extrusion seat 318 into the inner cavity of the second connecting rod 314, thereby reducing the elastic deformation of the spring 320 and thus reducing the extrusion force applied by the spring 320 to the ball 321. Step 2: Adjust the distance between the two cutting blades 39 according to factors such as the soybean variety to be cut and the material of the cutting blade 39. Start the two first motors 34. Use the output end of the first motors 34 to drive the turntable 36 to rotate through the first connecting rod 35. When the two turntables 36 rotate, the four connecting rods 37 can be used to pull the four support frames 33 to move up and down synchronously. Then the support frames 33 can be used to drive the cutting blades 39 to move up and down, thereby adjusting the distance between the two cutting blades 39. Step 3: Using the soybean harvester 1, move the machine and use the divider 2 to orderly separate the crops to be harvested from the unharvested crops. Guide the crops to be harvested smoothly and neatly towards the cutting mechanism 3. Start the second motor 313. The output of the second motor 313 drives the second connecting rod 314 to rotate. The rotation of the second connecting rod 314, through the engagement between the ball 321 and the slot 323, drives the gear 322 to rotate. The rotation of the gear 322 drives the gear disc 311 to rotate. The rotation of the gear disc 311 drives two... The drive rods 312 move circumferentially. Since the two drive rods 312 are respectively located on the front side of the top end and the rear side of the bottom end of the toothed disc 311, the circumferential movement of the two drive rods 312 can cooperate with the two drive slots 310 to drive the two cutting blades 39 to move synchronously left and right reciprocatingly. The two cutting blades 39 move in opposite directions. The soybean stalks can be cut using the two cutting blades 39 with opposite directions of movement. The cut soybean stalks can then be moved into the inner cavity of the soybean harvester 1 through the bridge. As the soybeans are harvested... During cutting, if the cutting blade 39 gets stuck in the soil due to human error or terrain conditions, or if it encounters a hard object, it will prevent the cutting blade 39 from continuing to move. When the resistance force exerted by the soil or hard object on the cutting blade 39 is greater than the elastic force of the spring 320, the second motor 313 drives the second connecting rod 314 to rotate. Since the hard object will prevent the cutting blade 39 from moving, it will also prevent the gear plate 311 from rotating under the action between the drive groove 310 and the drive rod 312, thereby preventing the gear 322 from following. The second connecting rod 314 rotates. When the second connecting rod 314 rotates, the inner wall of the slot 323 will squeeze the ball 321 to move into the inner cavity of the squeezing groove 315, and squeeze the spring 320 to undergo elastic deformation. This will cause the second motor 313 to drive the second connecting rod 314 to "idle". This will avoid the second motor 313 from being overloaded, avoid the risk of motor burnout, and prevent the cutting blade 39 from having chipped or rolled edges. In severe cases, the entire blade may twist or break, thus avoiding direct damage to the blade itself. Step 4: After the soybeans are harvested, the first motor 34 is started and the turntable 36 is rotated through the first connecting rod 35. The two cutting blades 39 are moved outward synchronously by the cooperation between the connecting rod 37 and the support frame 33, which increases the distance between the two cutting blades 39 and makes it easier to clean up the soybean straw fibers and other debris remaining between the two cutting blades 39.

[0019] This invention significantly improves the adaptability, cutting efficiency, equipment reliability, and maintenance convenience of soybean harvesters through designs such as adjustable cutting blade spacing, overload protection, and convenient cleaning. It effectively solves problems such as easy damage to cutting blades, easy overload of motors, and low operating efficiency in existing technologies.

[0020] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
