Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a harvesting machine with a new energy automatic steering function suitable for mountainous terrain. Background Technology

[0002] In mountainous agricultural operations, a harvesting machine with new energy automatic steering function is demonstrating unique advantages. It abandons traditional fuel power and adopts clean new energy drive, which is energy-saving, environmentally friendly and has low operating costs, meeting the needs of green agricultural development. Its automatic steering function is a major highlight. It can automatically adjust its direction of travel according to the complex terrain of the mountains. Whether it is a steep slope, a bend or an uneven field, it can flexibly cope with it, ensuring accurate and efficient harvesting operations and avoiding missed harvests and repeated work. With the integration of new energy and intelligent steering technology, this machine greatly improves the convenience and efficiency of mountain harvesting, reduces the labor intensity for farmers in mountainous areas, and becomes a powerful assistant in promoting the mechanization and modernization of mountain agriculture.

[0003] In actual use, existing harvesting machines often pre-treat crops after harvesting. However, existing machines have a single cleaning method, which makes it difficult to completely separate impurities and results in insufficient cleanliness. This makes it impossible to directly meet the grain depot's purchasing standards, and the cleaning rate is limited. This can easily lead to repetitive work, increasing time and labor costs. Therefore, a new type of harvesting machine with automatic steering function suitable for mountainous areas is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, where harvesting machinery often pre-processes crops after harvesting. However, existing devices have a single cleaning method, making it difficult to completely separate impurities, resulting in insufficient cleanliness and failing to directly meet grain depot purchasing standards. Furthermore, the cleanliness rate is limited, and repetitive operations are prone to occur, increasing time and labor costs. Therefore, this invention proposes a new energy-powered harvesting machinery with automatic steering function suitable for mountainous areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A new energy-efficient harvesting machine with automatic steering function suitable for mountainous terrain includes a main body. A collection box is fixedly connected to the top of the main body. A sorting chamber is provided on the upper part of the collection box. A feed pipe is fixedly connected to one side of the sorting chamber. A spiral conveying pipe is provided inside the main body. One end of the spiral conveying pipe is connected to the feed pipe. A first motor is provided on one side of the collection box. A first transmission wheel is provided at the output end of the first motor. The first transmission wheel is driven by a first transmission belt. The first transmission belt is driven by a second transmission wheel. An eccentric wheel is fixedly connected to the second transmission wheel. The eccentric wheel rotates... The device is equipped with a sieve plate, which is rotatably connected to the sorting chamber. A first worm gear is fixedly connected to the first transmission wheel, and the first worm gear meshes with a first worm wheel. A first transmission mechanism is fixedly connected to the first worm wheel, and a second transmission mechanism is fixedly connected to the first transmission mechanism. The second transmission mechanism is fixedly connected to a first impeller, and the first impeller is rotatably connected inside the feed pipe. An adjustment mechanism is provided at the front end of the main body of the device to adjust the height of the harvesting bucket off the ground. An automatic steering mechanism is also integrated on the upper part of the main body of the device to automatically turn according to the harvesting terrain. A threshing mechanism is provided inside the main body of the device. After harvesting, the crop is threshed by a threshing mechanism inside the main body of the device and then fed into a spiral conveyor pipe. The spiral conveyor pipe guides the crop into a feed pipe, where a first motor drives a first transmission wheel to rotate. This rotation of the first transmission wheel drives a first worm gear, which in turn drives a first impeller inside the feed pipe. This draws external gas into the feed pipe, carrying the grains into a collection box. Simultaneously, the rotation of the first transmission wheel drives a first transmission belt, which in turn moves a sieve plate back and forth to sieve the grains fed in from above. Inside the collection box, a combination of air separation and physical screening thoroughly separates impurities. Filter screens are installed on both sides of the collection box to prevent grains from falling. The sorting chamber opens upwards at the end furthest from the feed pipe, effectively preventing grains from being discharged by the airflow.

[0006] The above technical solution further includes: The first transmission mechanism includes a third transmission wheel fixedly connected to a first worm gear, the third transmission wheel being driven by a second transmission belt, and the second transmission belt being driven by a fourth transmission wheel.

[0007] The second transmission mechanism includes a fifth transmission wheel fixedly connected to a fourth transmission wheel, a third transmission belt drivingly connected to the fifth transmission wheel, a sixth transmission wheel drivingly connected to the third transmission belt, and a first impeller fixedly connected to the sixth transmission wheel.

[0008] The fifth transmission wheel is fixedly connected to the second impeller, which is rotatably connected to the air blowing housing, which is fixedly connected inside the main body of the device.

[0009] The threshing mechanism includes guide rollers installed inside the main body of the device. A crushing roller is installed at the rear end of the guide rollers, and a pressure roller is installed at the rear end of the crushing rollers. A guide plate is fixedly connected to the bottom of the pressure rollers, and a spiral conveying pipe is installed below the guide plate. A slag discharge shell is installed at the rear end of the main body of the device. The surface of the guide plate has slots, through which airflow blown from the air blowing shell is used to initially separate the grains. Baffles are installed at the bottom of the guide rollers and the crushing rollers, and there are three pressure rollers with screens at the bottom. The pressure rollers are wrapped with rubber, and the grains are separated by squeezing and friction, reducing breakage.

[0010] The automatic steering mechanism includes a triangular track at the bottom of the main body of the device, a lidar at the front end of the main body of the device, and a control module at a location near the lidar.

[0011] The adjustment mechanism includes an adjustment housing fixedly connected to the upper part of the device body, a second motor is provided inside the adjustment housing, and an adjustment component is provided at the output end of the second motor.

[0012] The adjustment assembly includes a second worm gear located at the output end of a second motor, the second worm gear being meshed with a second worm wheel, and the second worm wheel being rotatably connected to the adjustment housing.

[0013] The second worm gear is fixedly connected to a transmission gear, which meshes with a transmission rack. The transmission rack is slidably connected to the adjusting housing. A harvesting bucket is fixedly connected to the bottom of the transmission rack. A limit groove is provided inside the adjusting housing to allow the transmission rack to slide and ensure stability when the transmission rack moves.

[0014] The present invention has the following beneficial effects: 1. In this invention, after the crop is harvested by the harvesting bucket, the crop is pre-treated by the threshing mechanism inside the main body of the device. The threshed crop is then fed into the feed pipe through the spiral conveyor pipe at the bottom. Starting the first motor drives the first transmission wheel to rotate. The rotation of the first transmission wheel drives the first worm and the second transmission wheel to rotate synchronously. The rotation of the first worm drives the first and second transmission mechanisms to drive the first and second impellers to rotate synchronously. The rotation of the second impeller can initially separate the remaining large pieces of straw by air separation during the threshing process. The rotation of the first impeller induces airflow, which in turn drives the grains inside the feed pipe into the sorting chamber. The rotation of the second transmission wheel can drive the screen plate to move back and forth, thereby repeatedly screening the grains on the surface. Combined with the feeding airflow inside the feed pipe, a combined airflow and physical sorting method is realized, which effectively ensures the sorting effect of the grains.

[0015] 2. In this invention, the front end of the main body of the device integrates a lidar to monitor the position of the harvesting machinery in real time. The control module processes the sensor data to optimize and adaptively adjust the steering control. The triangular track set at the bottom of the main body of the device can disperse the pressure of the equipment on the ground, reduce the ground pressure, and prevent the harvester from getting stuck. Moreover, the stubble height can be adjusted through the adjustment mechanism to adapt to the undulating terrain of hilly areas. Attached Figure Description

[0018] 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.

[0019] Example 1 like Figures 1-6As shown, a new energy-efficient harvesting machine with automatic steering function suitable for mountainous terrain includes a main body 1. A collection box 9 is fixedly connected to the top of the main body 1. A sorting chamber 10 is provided on the upper part of the collection box 9. A feed pipe 7 is fixedly connected to one side of the sorting chamber 10. A spiral conveying pipe 16 is provided inside the main body 1. One end of the spiral conveying pipe 16 is connected to the feed pipe 7. A first motor 19 is provided on one side of the collection box 9. A first transmission wheel 20 is provided at the output end of the first motor 19. The first transmission wheel 20 is driven by a first transmission belt 23. The first transmission belt 23 is driven by a second transmission wheel 22. An eccentric wheel 31 is fixedly connected to the second transmission wheel 22. Wheel 31 is rotatably connected to screen plate 32, and screen plate 32 is rotatably connected to sorting chamber 10. First transmission wheel 20 is fixedly connected to first worm 21, first worm 21 is meshed with first worm wheel 24, first worm wheel 24 is fixedly connected to first transmission mechanism, and first transmission mechanism is fixedly connected to second transmission mechanism. Second transmission mechanism is fixedly connected to first impeller 17. First impeller 17 is rotatably connected inside feed pipe 7. An adjustment mechanism is set at the front end to adjust the height of harvesting bucket 2 off the ground. Automatic steering mechanism is also integrated on the upper part of the main body 1 of the device to automatically turn according to the harvesting terrain. Threshing mechanism is set inside the main body 1 of the device. After harvesting, the crop is threshed by the threshing mechanism inside the main body 1 and then fed into the spiral conveyor pipe 16. The spiral conveyor pipe 16 guides the crop into the feed pipe 7. The first motor 19 drives the first transmission wheel 20 to rotate, which in turn drives the first worm gear 21 to rotate, which in turn drives the first impeller 17 inside the feed pipe 7 to rotate. This draws external gas into the feed pipe 7, carrying the grains into the collection box 9. Simultaneously, the rotation of the first transmission wheel 20 drives the first transmission belt 23 to rotate, which in turn drives the sieve plate 32 to reciprocate and screen the grains fed in from above. Inside the collection box 9, a combination of air separation and physical screening is used to thoroughly separate impurities. Filter screens are installed on both sides of the collection box 9 to prevent grains from falling. The sorting chamber 10 opens at the end furthest from the feed pipe 7, and the opening faces upwards, effectively preventing grains from being discharged by the wind.

[0020] The first transmission mechanism includes a first worm gear 24 fixedly connected to a third transmission wheel 25. The third transmission wheel 25 is driven by a second transmission belt 26, and the second transmission belt 26 is driven by a fourth transmission wheel 27. The second transmission mechanism also includes a fourth transmission wheel 27 fixedly connected to a fifth transmission wheel 28, the fifth transmission wheel 28 being driven by a third transmission belt 29, and the third transmission belt 29 being driven by a sixth transmission wheel 30. The sixth transmission wheel 30 is fixedly connected to a first impeller 17, and the fifth transmission wheel 28 is fixedly connected to a second impeller 18. The second impeller 18 is rotatably connected to an air-blowing housing 14, and the air-blowing housing 14 is fixedly connected to the main body 1 of the device. Internally, the threshing mechanism includes a guide roller 11 installed inside the main body 1 of the device. A crushing roller 12 is installed at the rear end of the guide roller 11, and a pressure roller 13 is installed at the rear end of the crushing roller 12. A guide plate 15 is fixedly connected to the bottom of the pressure roller 13. A spiral conveying pipe 16 is installed at the lower part of the guide plate 15. A slag discharge shell 8 is installed at the rear end of the main body 1 of the device. A slot is opened on the surface of the guide plate 15. The airflow blown out by the air blowing shell 14 through the slot is used to initially separate the grains. Baffles are installed at the bottom of the guide roller 11 and the crushing roller 12. There are three pressure rollers 13 and a screen is installed at the bottom. The pressure rollers 13 are wrapped with rubber. The grains are separated by squeezing and friction, reducing breakage.

[0021] In this embodiment, after the harvester hopper 2 harvests the crops, the crops are first fed into the vicinity of the crushing roller 12 via the guide roller 11 for crushing. The crushing roller 12 breaks down the crop straw to facilitate subsequent threshing. The crushed crops are then fed into the bottom of the pressure roller 13. The crops are squeezed by the three pressure rollers 13 to release the grains. The threshed crops are then guided into the spiral conveying pipe 16 by the guide plate 15 at the bottom and fed into the feed pipe 7 under the drive of the spiral conveying pipe 16.

[0022] Starting the first motor 19 drives the first transmission wheel 20 to rotate. The rotation of the first transmission wheel 20 drives the first worm gear 21 (fixedly connected) and the second transmission wheel 22 (connected via the first transmission belt 23) to rotate synchronously. The rotation of the first worm gear 21 drives the first worm wheel 24 (meshing connection) to rotate. The rotation of the first worm wheel 24 drives the third transmission wheel 25 (fixedly connected) to rotate. The rotation of the third transmission wheel 25 drives the fourth transmission wheel 27 (connected via the second transmission belt 26) to rotate. The rotation of the fourth transmission wheel 27 drives the fifth transmission wheel 2 (fixedly connected) to rotate. When the fifth transmission wheel 28 rotates, it drives the fixedly connected second impeller 18 and the sixth transmission wheel 30 connected by the third transmission belt 29 to rotate synchronously. The rotation of the sixth transmission wheel 30 drives the fixedly connected first impeller 17 to rotate, thereby realizing the synchronous rotation of the first impeller 17 and the second impeller 18. The rotation of the second impeller 18 can initially separate the residual large pieces of straw during the threshing process, so that they are discharged through the slag discharge shell 8. The rotation of the first impeller 17 drives the air flow, so that the air flow carries the grains inside the feed pipe 7 into the sorting chamber 10.

[0023] After the grains enter the sorting chamber 10, the rotation of the second transmission wheel 22 can drive the fixedly connected eccentric wheel 31 to rotate. The rotation of the eccentric wheel 31 can drive the rotatingly connected screen plate 32 to move back and forth, thereby repeatedly screening the grains on the surface. Combined with the feeding airflow inside the feed pipe 7, a combined airflow and physical sorting method is realized, which effectively ensures the sorting effect of the grains.

[0024] Example 2 like Figures 1-6 As shown, the automatic steering mechanism includes a triangular track 6 at the bottom of the main body 1, a lidar 4 at the front end of the main body 1, and a control module 5 near the lidar 4.

[0025] The adjustment mechanism includes an adjustment housing 3 fixedly connected to the upper part of the main body 1 of the device. A second motor 33 is installed inside the adjustment housing 3. An adjustment component is installed at the output end of the second motor 33. The adjustment component includes a second worm 34 installed at the output end of the second motor 33. The second worm 34 is meshed with a second worm wheel 35. The second worm wheel 35 is rotatably connected to the adjustment housing 3. The second worm wheel 35 is fixedly connected to a transmission gear 36. The transmission gear 36 is meshed with a transmission rack 37. The transmission rack 37 is slidably connected to the adjustment housing 3. A harvesting bucket 2 is fixedly connected to the bottom of the transmission rack 37. A limit groove is provided inside the adjustment housing 3 to allow the transmission rack 37 to slide, ensuring the stability of the transmission rack 37 when it moves.

[0026] In this embodiment, the front end of the main body 1 of the device is equipped with a lidar 4, which can monitor the position of the harvesting machinery in real time through the air-blowing shell 14. Combined with the control module 5 set on the upper part of the main body 1, the sensor data is processed to achieve optimization and adaptive adjustment of steering control. The triangular track 6 set at the bottom of the main body 1 can disperse the pressure of the equipment on the ground, reduce the ground pressure, and prevent the harvester from getting stuck.

[0027] During harvesting, starting the second motor 33 drives the second worm 34 to rotate. The rotation of the second worm 34 drives the meshing second worm wheel 35 to rotate, and the rotation of the second worm wheel 35 drives the fixedly connected transmission gear 36 to rotate. The rotation of the transmission gear 36 drives the meshing transmission rack 37 to move, which in turn drives the fixedly connected harvesting bucket 2 to move up and down, thereby adjusting the stubble height to adapt to the undulating terrain of hilly areas, effectively keeping the harvesting head level and improving the accuracy of operation.

[0028] 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 variations 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.
