Description
Technical Field
[0001] This utility model relates to the technical field of seeding quality test bench for seeders, specifically, to a seeding quality test bench for corn seeders. Background Technology
[0002] The seeder sowing quality test bench is a specialized experimental device used to simulate the field sowing environment and test the performance of seeders. By precisely controlling parameters such as sowing speed, depth, and uniformity, and combining sensors and a data acquisition system, this test bench quantifies and analyzes sowing quality, providing a scientific basis for the optimized design of seeders.
[0003] An adjustable straw / soil separation test bench (publication number: CN103364213A) includes a frame assembly, a simulated no-till seeder ditching assembly, and a separation assembly. The frame assembly includes a main frame and an outer frame. The main body of the simulated no-till seeder ditching assembly is a loop conveyor belt, which is wound around the fixed end roller and the lifting end roller of the conveyor belt, and is mounted on the main frame via the lifting end bearing. The separation assembly includes a separation blade roller with a separation blade and an arc-shaped screen, with the arc-shaped screen positioned below the separation blade roller. The separation blade roller is installed parallel to the lifting end bearing of the loop conveyor belt. Based on the requirements of the seedbed and under simulated no-till seeder operation, it can rapidly, accurately, and continuously test the degree of separation between straw of different lengths and soil at different moisture contents.
[0004] The aforementioned patent achieves rapid, accurate, and continuous testing of the separation degree of straw of different lengths from the soil at different moisture contents by cooperating with components such as the frame assembly, the simulated no-till planter ditching operation assembly, and the separation assembly. However, it cannot achieve the effect of testing the sowing quality of corn planters. Therefore, we propose a corn planter sowing quality test bench. Utility Model Content
[0005] This invention proposes a corn planter sowing quality test bench, which solves the problem in related technologies that cannot achieve the effect of testing the sowing quality of corn planters.
[0006] According to one aspect, at least one embodiment of this disclosure provides a corn planter planting quality test bench, comprising: a base, support legs fixedly connected to the side of the base, and a transport detection simulation device disposed on the top of the base.
[0007] The transport detection simulation device includes a slot on the top of a base. A drive motor is fixedly connected to the side of the base, and a belt shaft is fixedly connected to the output shaft of the drive motor. A belt is mounted on the circumference of the belt shaft, and a belt pulley is connected to the belt shaft via belt drive. A rotating shaft is fixedly connected to the side of the belt pulley, and a conveyor belt is fixedly connected to the circumference of the rotating shaft. A support frame is fixedly connected to the top of the base, and a seed metering device is mounted on the top of the support frame. A conveying pipe is fixedly connected to the bottom of the seed metering device. This transport detection simulation device mainly achieves the transport and distribution of goods through the coordinated work of its components. It is suitable for various automated transport and detection scenarios, especially in agriculture and logistics, and can improve work efficiency and accuracy. It can achieve real-time collection and evaluation of indicators such as seed fall position, pitch, and missed / re-seeded seeds through the belt device and seed metering device, configured with seed placement recognition sensors and control units. This provides reliable testing support for research institutions, agricultural machinery colleges, and seeder manufacturers.
[0008] For example, in at least one embodiment of the corn planter planting quality test bench provided in this disclosure, a simulated material feeding trough is further included: the top of the conveyor belt is provided with a simulated material feeding trough, and the top of the simulated material feeding trough is located directly below the conveying pipe. The simulated material feeding trough plays an important role in the transport detection simulation device. It not only helps to achieve efficient material feeding and distribution, but also improves the operating efficiency and reliability of the entire system.
[0009] One end of the rotating shaft passes through the side of the base, and four support legs are provided. The design of four support legs not only improves the overall stability and load-bearing capacity of the equipment, but also provides convenience and protection for the installation, adjustment, and long-term use of the equipment.
[0010] The four support legs are respectively located at the four corners of the base, and there are two rotating shafts. The design of the four support legs enhances the stability and load-bearing capacity of the equipment, while the two rotating shafts provide a flexible movement mechanism and ease of operation, enabling the entire device to operate effectively in harsh working environments.
[0011] The system includes two seed metering devices and two delivery pipes, each fixedly connected to the bottom of one seed metering device. This dual arrangement of seed metering devices and delivery pipes plays a crucial role in improving operational efficiency, ensuring uniform seed distribution, and facilitating maintenance, significantly optimizing operation and management during the planting process.
[0012] A connecting plate is fixedly connected to the side of the base, and an infrared sensor is fixedly connected to the side of the connecting plate. The infrared sensor mounted on the connecting plate significantly improves the intelligence level and operational safety of the equipment by providing precise detection and control functions, thus playing a crucial role in applications such as agricultural and industrial automation.
[0013] The infrared sensors are electrically connected to the drive unit. Multiple infrared sensors are arranged in an array along the horizontal axis of the connecting plate. These sensors detect whether the seeds are placed in the center of the conveyor belt. The multiple infrared sensors, arrayed along the connecting plate and electrically connected to the drive unit, play a crucial role in seed placement detection. They not only improve the accuracy of seed placement and transportation efficiency but also greatly enhance the automation level and safety of the equipment, providing strong support for modern precision agriculture.
[0014] According to another aspect, at least one embodiment of this disclosure also provides a corn planter planting quality test bench, comprising: a trajectory correction device disposed on the top of the base, the trajectory correction device including a fixed plate, a motor fixedly connected to the side of the fixed plate, a threaded rod fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the threaded rod, a moving rod fixedly connected to the circumferential surface of the threaded sleeve, a push plate fixedly connected to the side of the moving rod, and a limit rod fixedly connected to the side of the fixed plate. The trajectory correction device, through the coordinated work of its various components, can efficiently achieve the trajectory correction function for moving objects. This not only improves the accuracy of operations and reduces errors, but also enhances the automation level of the equipment, enabling it to operate reliably in various application environments, effectively improving the efficiency and effectiveness of agricultural production.
[0015] For example, in at least one embodiment of this disclosure, a corn planter planting quality test bench further includes: two threaded sleeves, which are respectively disposed at both ends of the threaded rod and move towards each other. These features ensure that the configuration of two threaded sleeves provides good performance and reliability in the design of mechanical equipment, making it suitable for various industrial and mechanical applications.
[0016] The circumferential surfaces of the two threaded sleeves are slidably connected to the circumferential surface of the limiting rod. Two moving rods and push plates are provided, each fixedly connected to the circumferential surface of one of the two threaded sleeves, and the simulated material discharge trough is positioned on the displacement trajectory of the top displacement push plate. This structure not only improves the functional performance of the equipment but also ensures reliability and efficiency under complex working conditions.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. This utility model achieves real-time data collection and evaluation of indicators such as seed drop position, seed pitch, missed sowing, and reseeding. It utilizes the coordinated operation of components including a drive motor, belt, pulley, shaft, and conveyor belt. Starting the drive motor rotates the belt shaft, which in turn rotates the belt, driving the conveyor belt. This activates the seed metering device, which transports seeds through a conveying pipe to the simulated feeding trough. This provides reliable testing support for research institutions, agricultural machinery colleges, and seeder manufacturers.
[0019] 2. This utility model utilizes the coordinated operation of components such as a motor, infrared sensor, moving rod, threaded rod, and limiting rod. When the infrared sensor detects that the seed is not in the desired position, the drive motor automatically shuts off, the conveyor belt stops operating, and the operator starts the motor. The motor drives the threaded rod to rotate, which in turn causes two threaded sleeves to move horizontally towards each other under the constraint of the limiting rod. This horizontal movement of the two threaded sleeves causes two moving rods to move horizontally towards each other, which in turn causes two push plates to move horizontally towards each other, thus repositioning the seed that is no longer on the track. This highly efficient function corrects the trajectory of moving objects, improves operational accuracy, reduces errors, enhances the automation level of the equipment, and enables reliable operation in various application environments, effectively improving the efficiency and effectiveness of agricultural production.

[0030] like Figures 1-4 As shown, it illustrates a corn planter planting quality test bench according to an embodiment of the present disclosure, including: a base 1, a support leg 2 fixedly connected to the side of the base 1, and a transport detection simulation device 3 provided on the top of the base 1;
[0031] The transport detection simulation device 3 includes a slot 31 located on the top of a base 1. A drive motor 32 is fixedly connected to the side of the base 1. A belt shaft 33 is fixedly connected to the output shaft of the drive motor 32. A belt 34 is mounted on the circumferential surface of the belt shaft 33. A belt disc 35 is driven to the belt shaft 33 via the belt 34. A rotating shaft 36 is fixedly connected to the side of the belt disc 35. A conveyor belt 37 is fixedly connected to the circumferential surface of the rotating shaft 36. A support frame 38 is fixedly connected to the top of the base 1. A seed metering device 39 is mounted on the top of the support frame 38. A conveying pipe 310 is fixedly connected to the bottom of the seed metering device 39. This transport detection simulation device 3 mainly achieves the transport and distribution of goods through the coordinated operation of its components. It is suitable for various automated transport and detection scenarios, especially in agriculture and logistics, where it can improve work efficiency and accuracy. It can achieve real-time acquisition and evaluation of indicators such as seed drop position, pitch, and missed / re-seeded seeds by configuring a seed placement recognition sensor and control unit through the belt 34 and the seed metering device 39. It achieves the effect of providing reliable testing support for research and development institutions, agricultural machinery colleges, and seeder manufacturers.
[0032] In some examples, a simulated material discharge chute 311 is provided at the top of the conveyor belt 37, with the top of the simulated material discharge chute 311 located directly below the conveying pipe 310. The simulated material discharge chute 311 plays an important role in the transport detection simulation device 3, not only helping to achieve efficient material discharge and distribution, but also improving the operating efficiency and reliability of the entire system.
[0033] One end of the pivot 36 extends through the side of the base 1, and four support legs 2 are provided. The design of four support legs 2 not only improves the overall stability and load-bearing capacity of the equipment, but also provides convenience and protection for the installation, adjustment and long-term use of the equipment.
[0034] Four support legs 2 are respectively set at the four corners of the base 1, and two rotating shafts 36 are provided. The design of four support legs 2 enhances the stability and load-bearing capacity of the equipment, while the setting of two rotating shafts 36 provides a flexible movement mechanism and ease of operation, enabling the entire device to operate effectively in harsh working environments.
[0035] There are two seed metering devices 39 and two conveying pipes 310, with each conveying pipe 310 fixedly connected to the bottom of one seed metering device 39. The dual arrangement of seed metering devices 39 and conveying pipes 310 plays an important role in improving work efficiency, ensuring uniform seed distribution, and facilitating maintenance, greatly optimizing the operation and management during the planting process.
[0036] A connecting plate 312 is fixedly connected to the side of the base 1, and an infrared sensor 313 is fixedly connected to the side of the connecting plate 312. The infrared sensor 313 installed on the connecting plate 312 significantly improves the intelligence level and operational safety of the equipment by providing accurate detection and control functions, thus playing a vital role in applications such as agricultural and industrial automation.
[0037] Infrared sensors 313 are electrically connected to the drive unit 32. Multiple infrared sensors 313 are arranged in an array along the horizontal axis of the connecting plate 312. The infrared sensors 313 detect whether the seeds are placed at the center of the conveyor belt 37. These multiple infrared sensors 313, arrayed along the connecting plate 312 and electrically connected to the drive unit 32, play a crucial role in seed placement detection. They not only improve the accuracy of seed placement and transportation efficiency but also greatly enhance the automation level and safety of the equipment, providing strong support for modern precision agriculture.
[0038] For example, such as Figures 1-4 As shown, the drive motor 32 is started, which drives the belt shaft 33 to rotate. The rotation of the belt shaft 33 drives the belt 34 to rotate, which in turn drives the transmission belt disc 35 to rotate. The rotation of the belt disc 35 drives the rotating shaft 36 to rotate, which in turn drives the conveyor belt 37 to operate. The seed metering device 39 is started by the operator. The electronic control system issues a command, and the servo motor of the seed metering device 39 starts working. The internal precision gear set drives the seed metering wheel to rotate. The seed metering device 39 starts to transport seeds through the conveying pipe 310. Under the push of airflow or mechanical dials, the seeds flow orderly along the transparent polyethylene conveying pipe 310 and are finally delivered to the simulated feeding trough 311.
[0039] like Figures 1-4 As shown, this illustration depicts a corn planter planting quality test bench according to another embodiment of this disclosure. Its technical solution is largely the same as that of Embodiment 1, so only the differences are described in detail. These differences include: a trajectory correction device 4 is installed on the top of the base 1. The trajectory correction device 4 includes a fixed plate 41, a motor 42 fixedly connected to the side of the fixed plate 41, a threaded rod 43 fixedly connected to the output shaft of the motor 42, a threaded sleeve 44 threadedly connected to the circumferential surface of the threaded rod 43, a moving rod 45 fixedly connected to the circumferential surface of the threaded sleeve 44, a push plate 46 fixedly connected to the side of the moving rod 45, and a limit rod 47 fixedly connected to the side of the fixed plate 41. Through the coordinated operation of its various components, the trajectory correction device 4 can efficiently correct the trajectory of moving objects. This not only improves the accuracy of the operation and reduces errors but also enhances the automation level of the equipment, enabling it to operate reliably in various application environments and effectively improving the efficiency and effectiveness of agricultural production.
[0040] In some examples, two threaded sleeves 44 are provided, one at each end of the threaded rod 43, and they move towards each other. These features make the configuration of two threaded sleeves 44 in the design of mechanical equipment provide good performance and reliability, suitable for various industrial and mechanical applications.
[0041] The circumferential surfaces of the two threaded sleeves 44 are slidably connected to the circumferential surface of the limiting rod 47. Two moving rods 45 and push plates 46 are provided and are fixedly connected to the circumferential surfaces of the two threaded sleeves 44 respectively, simulating the displacement trajectory of the top displacement push plate 46 of the discharge chute 311. This structure not only improves the functional performance of the equipment, but also ensures reliability and efficiency under complex working conditions.
[0042] For example, such as Figures 1-4 As shown, when the infrared sensor 313 detects that the seed is not in the required position, the drive motor 32 automatically shuts down, the conveyor belt 37 stops operating, and the operator starts the motor 42. The motor 42 drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 causes the two threaded sleeves 44 to move horizontally towards each other under the restriction of the limit rod 47. The horizontal movement of the two threaded sleeves 44 causes the two moving rods 45 to move horizontally towards each other. The horizontal movement of the two moving rods 45 causes the two push plates 46 to move horizontally towards each other. The horizontal movement of the two push plates 46 moves horizontally towards each other, thereby moving and resetting the seed that is no longer on the track.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
