Description

Technical Field

[0001] This utility model belongs to the field of mechanical structure technology, specifically relating to a soybean separation and cutting platform. Background Technology

[0002] In the agricultural transportation sector, small and medium-sized full-feed combine harvesters are widely used. However, they have significant drawbacks when harvesting low-growing legumes such as soybeans and broad beans. Currently, these harvesters typically use rice and wheat headers for legume harvesting. Because legumes have low pod-bearing positions and the plants themselves, as well as the large amount of mud and sand entangled during harvesting, this directly leads to a decline in grain quality after harvesting, failing to meet market demand for high-quality legume products.

[0003] Existing headers specifically designed for harvesting legumes have seen some improvements. For example, a soybean combine harvester header (publication number CN114616976A) features a floating divider that mimics the terrain, effectively avoiding issues like soil shoveling and impact, thus improving operational reliability. However, these headers are functionally limited to legume harvesting and lack versatility. In actual agricultural production, farmers need to frequently change headers to accommodate different crops, significantly increasing labor intensity and time costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology by proposing a soybean separation header that can effectively solve the problem of reduced grain quality caused by mud and sand mixing during the harvesting of low-growing bean crops, while also being versatile and eliminating the need for frequent header replacements, thereby improving agricultural production efficiency and reducing production costs.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A soybean separating header includes a header main frame, the bottom of which is a header base plate. Shaft hole structures for installing header augers are respectively provided on both sides of the header main frame. A cutting component is installed on the front side of the header base plate. Several screen hole units are opened on the header base plate. A gate mechanism for controlling the passage of the screen hole units is installed at the bottom of the header base plate.

[0007] Preferably, the cutting table base plate includes a rear short plate and a front extension plate. The rear short plate is fixedly connected to the main frame of the cutting table, and the front extension plate is fixedly spliced ​​to the front end of the rear short plate. The sieve hole unit is formed on the front extension plate.

[0008] Preferably, the bottom of the cutting platform base plate is provided with a number of parallel reinforcing ribs at intervals along the length direction; the reinforcing ribs divide the cutting platform base plate into a number of opening areas, each opening area is provided with a sieve hole unit, and each sieve hole unit contains a number of sieve holes arranged in a matrix structure.

[0009] Preferably, the sieve holes are in the form of straight waist holes, and the distance between adjacent sieve holes is greater than the width of the sieve holes.

[0010] Preferably, the gate mechanism includes a gate adjustment unit and several gate bodies that correspond one-to-one with the opening areas. The surface of the gate body is provided with gate hole units that perfectly match the screen hole units. The gate body is in close contact with the bottom plate of the cutting table and is slidably connected to the bottom plate of the cutting table. Adjacent gate bodies are connected by screw assemblies. The gate adjustment unit is installed on the main frame of the cutting table or the bottom plate of the cutting table and is connected to one of the gate bodies to control all gate bodies to move left and right synchronously and lock.

[0011] Preferably, in each of the opening areas, two parallel limiting plates are provided on the front and rear sides of the gate body; the limiting plates are fixedly connected to the bottom plate of the cutting table, and form a guide groove structure for installing the corresponding gate body between the limiting plates and the bottom of the bottom plate of the cutting table.

[0012] Preferably, in each of the opening areas, spring steel plates are respectively provided on the front and rear sides of the gate body; the spring steel plates are fixedly connected to the bottom plate of the cutting table to ensure that the gate body and the bottom of the cutting table are tightly fitted.

[0013] Preferably, the gate adjustment unit includes a fixed base, a connecting base, an adjustment handle, a locking nut, and an adjustment screw; the fixed base is fixedly connected to the main frame of the cutting table or the bottom plate of the cutting table, and the connecting base is fixedly connected to a gate body; one end of the adjustment screw is fixedly connected to the adjustment handle, and the other end of the adjustment screw spirally passes through the locking nut and the fixed base in sequence, and is then rotatably connected to the connecting base.

[0014] Preferably, the screw assembly includes a connecting screw and two connecting seats; the two connecting seats are respectively fixedly installed on two adjacent gate bodies, the connecting screw passes through the corresponding reinforcing rib structure, and the two ends of the connecting screw are respectively fixedly connected to the two connecting seats through nut assemblies.

[0015] Preferably, dividers are installed on the left and right sides of the main frame of the header.

[0016] This technical solution has the following beneficial effects:

[0017] 1) High-efficiency mud and sand separation function: By setting sieve hole units (especially straight waist-shaped sieve holes) on the bottom plate of the header, mud and sand carried by the crop can be separated in real time during harvesting, significantly improving the cleanliness of legume grains and solving the quality decline problem caused by traditional rice and wheat headers. The design of sieve hole spacing greater than hole width ensures mud and sand passage rate while preventing grain leakage.

[0018] 2) Modular and universal design: The gate mechanism can control the opening and closing of the screen holes through synchronous movement, enabling the same header to quickly switch between legume crops (requiring soil sieving) and other crops (such as rice and wheat, which do not require soil sieving) without replacing the header body. 3) Improved structural strength and reliability: The reinforcing rib structure divides the base plate into independent opening areas, enhancing overall rigidity; guide grooves and spring steel plates ensure a tight fit of the gate, preventing jamming or soil leakage; the screw assembly enables linkage between the gate body and the machine, resulting in high operational stability.

[0019] 4) Optimized ease of operation: The gate adjustment unit adopts screw-nut transmission, and precise control is achieved by adjusting the handle and locking nut. Combined with the limit plate design, the screen opening adjustment is intuitive and reliable, reducing the risk of misoperation.

[0020] 5) Adaptability and expansion capability: The combination of the divider and the floating structure (in conjunction with existing improvements in the background technology) can further enhance the adaptability to complex terrain, ensuring that the cutting platform is always close to the ground surface during the harvesting process, reducing missed cutting and soil removal.

[0021] 6) Reduced maintenance costs: The modular design allows for independent replacement of individual gate bodies or screen areas, making maintenance convenient; the overall structure is simplified, reducing mechanical wear caused by frequent replacement of traditional cutting tables.

[0034] Example 1

[0035] This embodiment discloses a soybean separating and harvesting platform, as a preferred implementation of this technical solution, such as... Figure 1, Figure 2 and Figure 3 As shown, it includes the main frame 1 of the cutting table, which is welded from high-strength aluminum alloy profiles and has an overall inverted trapezoidal shape.

[0036] The bottom of the main frame 1 of the cutting table is the cutting table base plate 5. The cutting assembly 3 is fixed to the front side of the cutting table base plate 5 by bolts. The cutting assembly 3 can be a double moving blade reciprocating structure, which includes two sets of moving blades driven by hydraulic motors and one set of fixed blades. The moving blades and fixed blades are made of SKD11 tool steel and the cutting edge is laser hardened.

[0037] Shaft hole structures 2 are symmetrically distributed on both sides of the main frame 1 of the cutting table. Bearing seats can be installed in the shaft hole structures 2 to fix the cutting table auger.

[0038] A number of screen hole units 4 are evenly provided on the bottom plate 5 of the cutting table. A gate mechanism 7 for controlling the passage of the screen hole units 4 is installed at the bottom of the bottom plate 5 through a sliding fit structure. The gate mechanism 7 can be driven by a servo motor through a lead screw and nut pair to move left and right. It can be set so that the gate mechanism 7 moves to the left to block the screen hole units 4 and moves to the right to allow the screen hole units 4 to pass through.

[0039] Example 2

[0040] This embodiment discloses a soybean separation header, as a preferred implementation of this technical solution and an optimized improvement of Embodiment 1. Based on Embodiment 1, the header base plate 5 adopts a partitioned structural design, comprising a rear short plate 5.1 and a front extension plate 5.2. The rear short plate 5.1 is fixedly connected to the header main frame 1. The front extension plate 5.2 can be integrally formed with the rear short plate 5.1, or it can be detachably spliced ​​with the rear short plate 5.1 using high-strength bolts to form a complete header base plate 5. This structure allows the sieve holes 4 to be concentrated in the area of ​​the front extension plate 5.2, facilitating precise control of the initial separation of the cut material. The front extension plate 5.2 extends to a certain position behind the cutting assembly 3, forming an independent cleaning operation area. The sieve holes 4 are distributed in a specific arrangement in this area, which can effectively improve soil screening efficiency.

[0041] Example 3

[0042] This embodiment discloses a soybean separating header, which is a preferred implementation of this technical solution and an optimized improvement of embodiment 1 or 2. Based on embodiment 1 or 2, the bottom of the header base plate 5 is provided with a number of parallel reinforcing rib structures 6 along the length direction. The reinforcing rib structure 6 is a key support structure of the header base plate 5, and its core function is to improve the overall strength and rigidity of the header base plate 5 and effectively resist the mechanical stress and deformation risk generated during operation.

[0043] The reinforcing rib structure 6 divides the bottom plate 5 of the cutting platform into several opening areas. Each opening area is equipped with a screen unit 4, so that the gate mechanism 7 can be arranged to control the passage of the screen unit 4 under the condition of the reinforcing rib structure 6. Each screen unit 4 contains several soil screening holes 4.1 arranged in a matrix structure, which not only ensures sufficient soil screening area, but also makes it easy to control the passage of the soil screening holes 4.1.

[0044] Example 4

[0045] This embodiment discloses a soybean separation header, as a preferred implementation of this technical solution and an optimized improvement of Embodiment 3. Based on Embodiment 3, the soil screening holes 4.1 adopt a straight, waist-shaped structure, with their long axis aligned with the front-rear direction of the header device. The distance between adjacent soil screening holes 4.1 is greater than the width of the holes. This design, through the principle of hole misalignment, enables the gate mechanism 7 to precisely control the opening and closing state of the soil screening holes 4.1. Furthermore, the long axis design of the soil screening holes 4.1 allows for a longer contact path between the material and the screen holes during transport, improving soil separation efficiency.

[0046] Based on this, the gate mechanism 7 can adopt a comb-like structure that matches the soil screening holes 4.1, with the spacing between the comb teeth forming a specific proportional relationship with the spacing between the soil screening holes 4.1. When the gate mechanism 7 moves in the left and right direction, the comb teeth and the soil screening holes 4.1 are misaligned or overlapped.

[0047] Fully open state: The comb teeth completely avoid the area of ​​sieve holes 4.1, and all sieve holes 4.1 are at their maximum opening.

[0048] Adjustment state: By controlling the displacement of the gate mechanism 7, the proportion of the comb teeth covering the screen holes 4.1 is changed, thereby achieving stepless adjustment of the opening degree.

[0049] Closed state: The comb teeth completely cover the sieve holes 4.1, blocking the passage of materials.

[0050] Example 5

[0051] This embodiment discloses a soybean separating and harvesting platform, as a preferred implementation of this technical solution, such as... Figure 4 As shown, as an optimized and improved scheme of embodiment 3 or 4, that is, based on embodiment 3 or 4, the gate mechanism 7 adopts a modular structure design, including a gate adjustment unit 7.1 and several gate bodies 7.2. Each gate body 7.2 corresponds one-to-one with the opening area divided by the reinforcing rib. The surface of the gate body 7.2 is provided with gate hole units 7.3 that are completely matched with the screen hole unit 4.

[0052] The gate body 7.2 is designed to be tightly fitted to the cutter base plate 5, and is slidably connected to the cutter base plate 5 from left to right using a dovetail groove guide structure or other sliding connection structure. The tight-fitting sealing design between the gate body 7.2 and the cutter base plate 5 effectively prevents material from entering the gap between the gate and the base plate, avoiding the problem of the gate body 7.2 getting stuck due to the accumulation of soil particles or straw debris, and also greatly reducing the probability of material fiber entanglement causing blockage of the screen holes 4.1.

[0053] Furthermore, the gate mechanism 7 of this technical solution adopts a linkage control mechanism. Specifically, all gate bodies 7.2 are connected end-to-end via screw assemblies 7.4 to form a linkage structure. The gate adjustment unit 7.1 is installed on the main frame 1 of the cutting table or the base plate 5 of the cutting table and connected to one of the gate bodies 7.2. With the cooperation of the linkage structure, synchronous left and right movement and locking control of all gate bodies 7.2 are achieved. This design ensures the consistency of the opening degree of the screening holes 4.1 in each hole area, making operation convenient and quick, while avoiding uneven material screening and cleaning caused by local adjustment differences. The gate mechanism 7 incorporates a mechanical locking structure, which can lock the gate body 7.2 at any opening position to prevent displacement deviation caused by operational vibration.

[0054] This technical solution, while maintaining the strength of the reinforcing rib structure (6), achieves precise control and flexible adjustment of the screening hole area (4.1) through a modular gate body (7.2) and a linkage control mechanism. It is particularly suitable for multi-condition operation, allowing for rapid switching between different cleaning modes while reducing maintenance complexity.

[0055] Example 6

[0056] This embodiment discloses a soybean separating header, as a preferred implementation of this technical solution and an optimized improvement of Embodiment 5. Based on Embodiment 5, in each opening area, two parallel limiting plates 8 are provided on the front and rear sides corresponding to the gate body 7.2. The limiting plates 8 are made of high-strength alloy steel and are fixedly connected to the bottom surface of the header base plate 5 by welding or bolts, forming a guide groove structure between them for installing the corresponding gate body 7.2. The width of the guide groove structure precisely matches the thickness of the gate body 7.2. The gate body 7.2 is embedded in the guide groove structure, achieving smooth left and right movement through the guiding action of the guide groove structure. A wear-resistant pad can be provided on the bottom surface of the guide groove structure to reduce sliding friction resistance.

[0057] Example 7

[0058] This embodiment discloses a soybean separating header, as a preferred implementation of this technical solution, and as an optimized improvement of embodiment 5 or 6. Based on embodiment 5 or 6, in each of the opening areas, spring steel plates 9 are respectively provided on the front and rear sides of the gate body 7.2. One end of the spring steel plate 9 is fixedly connected to the bottom surface of the header base plate 5 by bolts, and the other end (free end) extends towards the gate body 7.2, forming an elastic cantilever structure. The free end of the spring steel plate 9 contacts the gate body 7.2, and the elastic force generated by pre-compression tightly presses the gate body 7.2 onto the bottom surface of the header base plate 5. When the gate body 7.2 moves left and right, the elastic deformation of the spring steel plate 9 always maintains the contact pressure, ensuring that there is essentially no gap between the spring steel plate 9 and the gate body 7.2, and between the gate body 7.2 and the header base plate 5.

[0059] The spring steel plate 9 in this technical solution is designed to achieve an adaptive compensation function. That is, the elastic modulus of the spring steel plate 9 is optimized to compensate for the small displacement caused by thermal expansion and contraction or mechanical deformation of the cutter base plate 5, ensuring that the gate body 7.2 and the cutter base plate 5 always maintain a "zero" gap fit.

[0060] Example 8

[0061] This embodiment discloses a soybean separating and harvesting platform, as a preferred implementation of this technical solution, such as... Figure 5 As shown, as an optimized improvement of Embodiments 5, 6, or 7, i.e., based on Embodiments 5, 6, or 7, the gate adjustment unit 7.1 includes a fixed base 7.11, a connecting base 7.12, an adjusting handle 7.13, a locking nut 7.14, and an adjusting screw 7.15. The fixed base 7.11 is fixedly connected to the main frame 1 of the cutting table or the base plate 5 of the cutting table, serving as the installation reference for the adjustment unit. The connecting base 7.12 is fixedly connected to a gate body 7.2 for transmitting adjustment displacement. One end of the adjusting screw 7.15 is fixedly connected to the adjusting handle 7.13, and the other end of the adjusting screw 7.15 spirally passes through the locking nut 7.14 and the fixed base 7.11 in sequence, and then is rotatably connected to the connecting base 7.12. Thus, the adjusting screw 7.15 engages with the fixed base 7.11 through a threaded pair to achieve linear motion conversion. When the adjusting handle 7.13 is rotated, the helical motion of the adjusting screw 7.15 converts the rotational force into linear displacement of the connecting base 7.12 through the threaded joint, thereby driving the connected gate body 7.2 to move. Under the action of the screw assembly 7.4, all gate bodies 7.2 move synchronously. After adjusting to the desired opening degree, tightening the locking nut 7.14 can lock the relative position of the adjusting screw 7.15 and the fixed base 7.11, preventing displacement of the gate body 7.2 caused by operational vibration.

[0062] Example 9

[0063] This embodiment discloses a soybean separating and harvesting platform, as a preferred implementation of this technical solution, such as... Figure 6 As shown, as an optimized improvement of embodiments 5, 6, 7, or 8, i.e., based on embodiments 5, 6, 7, or 8, the screw assembly 7.4 includes a high-strength connecting screw 7.41 and two connecting seats 7.42. The two connecting seats 7.42 are made of alloy steel and are respectively fixedly installed on two adjacent gate bodies 7.2 by welding or bolts. The connecting screw 7.41 passes through the corresponding reinforcing rib structure 6, and both ends of the connecting screw 7.41 are fixedly connected to the two connecting seats 7.42 by nut assemblies 7.43. The nut assembly 7.43 adopts a double-nut anti-loosening design to ensure stability under complex working conditions.

[0064] Therefore, when the gate adjustment unit 7.1 drives one of the gate bodies 7.2 to move, the displacement is transmitted to the adjacent gate bodies 7.2 through the rigid connection between the connecting screw 7.41 and the connecting seat 7.42, ultimately achieving synchronous linkage of all gate bodies 7.2. The reinforcing rib structure 6 provides a fulcrum for the screw assembly 7.4, forming a stable transmission chain.

[0065] Example 10

[0066] This embodiment discloses a soybean separating harvester, as a preferred implementation of this technical solution, and as an optimized improvement of any of embodiments 1-9. Specifically, based on any of embodiments 1-9, dividers 10 are installed on the left and right sides of the main frame 1 of the harvester. The dividers 10 are made of high-strength alloy material and are fixedly connected to the sides of the main frame 1 of the harvester by bolts or welding. When the combine harvester moves, the guide teeth of the dividers 10 cut into the crop roots, pushing the crop stems to both sides to form independent harvesting channels. Through an angle adjustment mechanism, the dividers 10 can adapt to lodged crops or high-density planting scenarios, ensuring that the cutting component 3 accurately grasps the target crop.
