Description

Technical Field

[0001] This invention relates to the field of agricultural crop harvesting technology, specifically to an agricultural crop combine harvester. Background Technology

[0002] Agricultural crops are an important resource for human survival. They are mainly divided into several categories, such as food crops, cash crops, vegetables, and fruits. Food crops, such as rice, wheat, corn, and sorghum, are the main source of energy for humans. Different regions grow crops suitable for their local environment based on natural conditions such as climate and soil. The development of modern agricultural technologies, such as hydroponics and genetic modification, is also constantly improving the yield and quality of crops.

[0003] Harvesters are mechanical equipment used in agricultural production to harvest grains. They are mainly divided into combine harvesters and silage harvesters. Combine harvesters are multi-functional harvesting equipment that can complete the harvesting, threshing, separation and cleaning of crops in one go. They are suitable for harvesting various grains such as wheat, rice, corn and sorghum.

[0004] Different varieties of sorghum vary in plant height, stem strength, and flexibility. Some tall varieties or varieties with weak lodging resistance are more likely to be flattened or collapsed when faced with severe weather. When the planting density is too high, the sorghum plants block each other's sunlight and compete for nutrients and space, resulting in poor growth of some sorghum plants, thin and weak stems, poor ventilation and light penetration, and susceptibility to pests and diseases, which in turn increases the risk of lodging.

[0005] The main reason why lodged sorghum is difficult to harvest by combine harvesters is that the design and operation of the harvesters are not compatible with the physical state of the lodged sorghum. First, the harvester's blades cannot get close to the ground and cannot accurately cut the lodged sorghum stalks. Second, the stalks of the lodged sorghum are intertwined, making it impossible for the harvester to cut them neatly and transport them effectively. In addition, the standardized operating mode of the harvester cannot flexibly adapt to the irregular state of the lodged sorghum, which reduces harvesting efficiency.

[0006] Therefore, it is necessary to design a combine harvester for agricultural crops that can harvest lodged sorghum. Summary of the Invention

After capturing the images, the camera converts them into electrical signals and sends them to the judgment module. The judgment module then compares these images with identification photos of sorghum stalks in different lodging directions in its internal database. By pre-identifying the lodging direction of the sorghum, the module controls the support mechanism to move in different ways, accurately lifting the sorghum stalks in different lodging directions and assisting the cutting mechanism in cutting. This effectively prevents the harvester's blades from failing to get close to the ground and accurately cut the lodged sorghum stalks, achieving a high efficiency in sorghum cutting.

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.

[0032] Please see Figure 1-7 The present invention provides a technical solution: an agricultural crop combine harvester, including a base 1, a track 2 for driving the harvester to move on the lower side of the base 1, a driver's seat 4 fixedly connected to the upper side of the base 1, a control box 3 fixedly connected to one side of the base 1, a threshing mechanism 5 for separating and screening grains from stalks on one side of the driver's seat 4, a conveying mechanism 6 for conveying the harvested crops into the threshing mechanism 5 on one side of the threshing mechanism 5, a cutting mechanism 7 for cutting and conveying the crops on one side of the conveying mechanism 6, a monitoring mechanism 8 for monitoring the lodging direction of sorghum in front of the harvester on one side of the cutting mechanism 7, and a support mechanism 9 for lifting up sorghum that has lodged in different directions and assisting in cutting it on one side of the cutting mechanism 7.

[0033] Please see Figure 3 and Figure 4 The cutting mechanism 7 includes a receiving cylinder 71 fixedly connected to one side of the conveying mechanism 6. The receiving cylinder 71 is equipped with a spiral conveying assembly 79 for conveying the cut crops to the transmission area of ​​the conveying mechanism 6.

[0034] The following is a supplementary explanation based on the above structure: the shearing assembly 78 is used to cut the lower end of the sorghum, the rotation of the output end of the first motor 74 is used to drive the connecting shaft 76 to rotate, thereby indirectly driving the dividing plate 771 to rotate, and then pushing the cut crop into the inside of the receiving cylinder 71.

[0035] The monitoring mechanism 8 includes a support column 81 fixedly connected to the upper side of the first support plate 72, and a camera 82 is fixedly connected to the upper side of the support column 81.

[0036] The following is a supplementary explanation based on the above structure: The control box 3 is equipped with a database and a judgment module. The database contains identification photos of sorghum with different lodging directions. The camera 82 is used to capture images of the sorghum in front of the harvester. After the camera 82 captures the image of the sorghum in front of the harvester, it converts the image into an electrical signal and sends it to the judgment module. The judgment module compares it with the identification photos of sorghum with different lodging directions in the internal database, identifies the lodging direction of the sorghum in advance, and classifies the lodging direction of the sorghum into front lodging, rear lodging, left lodging, and right lodging based on the obtained photos of the sorghum in front of the harvester.

[0037] Please see Figures 5-7 The support mechanism 9 includes a second fixed plate 94 and a first fixed plate 95 respectively fixedly connected to one side of the two second support plates 73. A first connecting column 92 is connected to one side of the first fixed plate 95 by a bearing, and a second connecting column 93 is connected to one side of the second fixed plate 94 by a bearing. A rotating component 91 is provided between the first connecting column 92 and the second connecting column 93. A second motor 97 is fixedly connected to the other side of the second fixed plate 94. The output end of the second motor 97 passes through the second fixed plate 94 and is fixedly connected to the second connecting column 93.

[0038] The following is a supplementary explanation based on the above structure: the rotation of the output end of the second motor 97 is used to drive the rotating component 91 to rotate around the second connecting column 93 as the axis, thereby indirectly driving the first electric gripper 982 and the second electric gripper 962 to rotate around the second connecting column 93 as the axis.

[0039] The rotating assembly 91 has a second rotating column 961 and a first rotating column 981 on both sides respectively. A second electric push rod 96 is fixedly connected to one end of the second rotating column 961, and a first electric push rod 98 is fixedly connected to one end of the first rotating column 981. A second fixing block 964 is fixedly connected to the output end of the second electric push rod 96, and a first fixing block 984 is fixedly connected to the output end of the first electric push rod 98.

[0040] The following is a supplementary explanation based on the above structure: the extension of the output end of the first electric push rod 98 is used to drive the first electric gripper 982 to move forward, and the extension of the output end of the second electric push rod 96 is used to drive the second electric gripper 962 to move forward.

[0041] A fourth motor 985 is fixedly connected to the lower side of the first fixing block 984. The output end of the fourth motor 985 passes through the first fixing block 984 and is fixedly connected to the first electric gripper 982. The gripping end of the first electric gripper 982 is fixedly connected to the first triangular clamping plate 983. A third motor 965 is fixedly connected to the lower side of the second fixing block 964. The output end of the third motor 965 passes through the second fixing block 964 and is fixedly connected to the second electric gripper 962. The gripping end of the second electric gripper 962 is fixedly connected to the second triangular clamping plate 963.

[0042] The following is a supplementary explanation based on the above structure: the movement of the clamping ends of the first electric gripper 982 and the second electric gripper 962 is used to drive the two first triangular clamping plates 983 and the two second triangular clamping plates 963 to move closer or further apart, thereby clamping or loosening the upper end of the fallen sorghum.

[0043] The rotating assembly 91 includes a rotating cylinder 912 fixedly connected between the first connecting post 92 and the second connecting post 93. A cylinder 911 is fixedly connected to one side of the rotating cylinder 912. A first sliding groove 9121 and a second sliding groove 9122 are respectively provided on the outer side of the rotating cylinder 912. Both the first sliding groove 9121 and the second sliding groove 9122 are semi-circular arc grooves. The output end of the cylinder 911 passes through the rotating cylinder 912 and is fixedly connected to a fifth motor 913.

[0044] The output end of the fifth motor 913 is fixedly connected to a slide column 914. The outer side of the slide column 914 is fixedly connected to a second locking block 916. The inside of the rotating cylinder 912 is rotatably connected to a first rotating disk 917 and a second rotating disk 918. The outer side of the first rotating disk 917 is fixedly connected to a first slider, and the outer side of the second rotating disk 918 is fixedly connected to a second slider.

[0045] The first slider is slidably connected to the first slide groove 9121 and fixedly connected to the first rotating column 981. The second slider is slidably connected to the second slide groove 9122 and fixedly connected to the second rotating column 961. The first rotating disk 917 has a first slot 9171 inside, and the second rotating disk 918 has a second slot 9181 inside. The second locking block 916 can be locked into the first slot 9171 and the second slot 9181.

[0046] The following is a supplementary explanation based on the above structure: a third slider is fixedly connected to the outside of the fifth motor 913, and a third slide groove is provided inside the rotating cylinder 912. The third slider is slidably connected to the third slide groove. The fifth motor 913 is slidably connected to the inside of the rotating cylinder 912 through the third slider and the third slide groove. The extension and retraction of the output end of the cylinder 911 is used to drive the fifth motor 913 to slide along the inside of the rotating cylinder 912, thereby indirectly driving the second locking block 916 to move, and then inserting the second locking block 916 into the inside of the first locking slot 9171 and the second locking slot 9181 respectively. The rotation of the output end of the fifth motor 913 is used to drive the first rotating disk 917 to rotate along the first slide groove 9121, and the second rotating disk 918 to rotate along the second slide groove 9122.

[0047] When cylinder 911 is fully retracted, the second locking block 916 engages with the inside of the first locking slot 9171. When cylinder 911 is fully extended, the second locking block 916 engages with the inside of the second locking slot 9181.

[0048] When camera 82 captures the sorghum falling forward, the judgment module determines that the sorghum has fallen forward. The output end of the first electric push rod 98 extends, moving the first fixed block 984 forward, and indirectly moving the first electric gripper 982 forward. The output end of the second electric push rod 96 extends, moving the second fixed block 964 forward, and indirectly moving the second electric gripper 962 forward, until the second fixed block 964 and the first fixed block 984 reach the fallen end of the forward-falling sorghum. The fourth motor 985 controls the first electric gripper 982 to rotate 90 degrees clockwise, and the third motor 965 controls the second... The electric gripper 962 rotates 90 degrees counterclockwise. At this time, the second triangular clamping plate 963 and the first triangular clamping plate 983 are aligned with each other, and the second triangular clamping plate 963 and the first triangular clamping plate 983 are controlled to clamp the fallen end of the forward-fallen sorghum. The output end of the second motor 97 rotates counterclockwise, thereby indirectly driving the second triangular clamping plate 963 and the first triangular clamping plate 983 to rotate around the second connecting column 93 as the axis, thereby lifting the forward-fallen sorghum and assisting the cutting mechanism 7 in cutting. After the sorghum is cut, the second triangular clamping plate 963 and the first triangular clamping plate 983 return to their original positions.

[0049] When camera 82 captures a view of the sorghum falling backward, the judgment module determines that the sorghum has fallen behind it. The output end of the first electric push rod 98 extends, moving the first fixed block 984 forward, and indirectly moving the first electric gripper 982 forward. The output end of the second electric push rod 96 extends, moving the second fixed block 964 forward, and indirectly moving the second electric gripper 962 forward. Simultaneously, the fourth motor 985 controls the first electric gripper 982 to rotate 90 degrees clockwise, and the third motor 965 controls the second electric gripper 962 to rotate 90 degrees counterclockwise. At this point, the second triangular clamp 963 and the first triangular clamp 983 are aligned until the... The two fixing blocks 964 and the first fixing block 984 reach the fallen end of the backward-fallen sorghum and control the second triangular clamp 963 and the first triangular clamp 983 to clamp the fallen end of the backward-fallen sorghum. The output end of the second motor 97 rotates counterclockwise, thereby indirectly driving the second triangular clamp 963 and the first triangular clamp 983 to rotate around the second connecting column 93 as the axis. At the same time, the output ends of the first electric push rod 98 and the second electric push rod 96 extend simultaneously, thereby lifting the backward-fallen sorghum and assisting the cutting mechanism 7 in cutting. After the sorghum is cut, the second triangular clamp 963 and the first triangular clamp 983 return to their original positions.

[0050] When camera 82 captures a sorghum stalk falling to the left, the judgment module determines that the sorghum has fallen to the left. The output end of the first electric push rod 98 extends, driving the first fixed block 984 forward, and indirectly driving the first electric gripper 982 forward, until most of the fallen sorghum ends are inserted between the two first triangular clamps 983. At the same time, cylinder 911 retracts completely, the second locking block 916 engages with the inside of the first locking slot 9171, and the fifth motor 913 rotates counterclockwise, thereby driving the first triangular clamp 983 to rotate counterclockwise around the sliding column 914 as the axis, thus lifting the fallen sorghum to the left and assisting the cutting mechanism 7 in cutting. After the sorghum is cut, the first triangular clamp 983 returns to its original position.

[0051] When camera 82 captures a rightward lodging of the sorghum, the judgment module determines that the sorghum has lodged to the right. The output end of the second electric push rod 96 extends, driving the second fixed block 964 forward, and indirectly driving the second electric gripper 962 forward, until most of the rightward lodged sorghum ends are inserted between the two second triangular clamps 963. At the same time, cylinder 911 extends fully, the second locking block 916 engages with the inside of the second locking slot 9181, and the fifth motor 913 rotates clockwise, thereby driving the second triangular clamp 963 to rotate clockwise around the sliding column 914 as the axis, thus lifting the rightward lodged sorghum and assisting the cutting mechanism 7 in cutting. After the sorghum is cut, the second triangular clamp 963 returns to its original position.

[0052] During harvesting operations, the camera 82 captures real-time images of the sorghum in front of the harvester. After capturing the images, the camera 82 converts them into electrical signals and sends them to the judgment module. The judgment module then compares these images with identification photos of sorghum with different lodging directions in its internal database, pre-identifying the lodging direction of the sorghum. This allows the support mechanism 9 to be controlled to move in different ways, accurately lifting the sorghum with different lodging directions and assisting the cutting mechanism 7 in cutting. This effectively prevents the harvester's blades from being unable to get close to the ground and accurately cut the lodged sorghum stalks, achieving a high efficiency in sorghum cutting.
