Description

Technical Field

[0001] This invention relates to the field of sowing equipment technology, and more specifically, to a test seeder, and also to a corn field test system based on an artificial intelligence system. Background Technology

[0002] To improve sowing efficiency, large-scale agricultural production activities typically utilize sowing equipment for mechanized or semi-mechanized operations, which greatly enhances the efficiency of agricultural sowing.

[0003] Currently, the most commonly used sowing equipment is the roller type, where the sowing mechanism is mounted on a roller. As the roller rolls across the field, multiple sowing mechanisms distributed on it sow seeds across the surface, resulting in high sowing efficiency. However, the sowing depth is relatively shallow, making it difficult to control the sowing quality. Another type is the tubular sowing device, which has an opening and closing tip at the bottom. This tip can penetrate the soil to a certain depth, but it is prone to clogging during sowing, allowing soil to enter the sowing tube and preventing the seeds from falling smoothly, which is also detrimental to the quality of the sown seeds.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0027] 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.

[0028] Example 1

[0029] This embodiment discloses an experimental seeder, referring to... Figures 1-6 As shown, the device includes a support frame 1, a storage box 5, and a sowing device 3. The support frame 1 serves as a support, and a fixed frame 2 is fixedly connected to the upper part of the support frame 1. The storage box 5 is located on the fixed frame 2 and stores the seeds to be sown. The sowing device 3 is installed on the side of the support frame 1 and serves to sow the seeds.

[0030] Specifically, a connection port is provided at the bottom of the storage box 5, and a control valve 6 is installed at the connection port. When the control valve 6 is working, it can quantitatively control the falling of seeds, and the number of seeds can be counted by a photoelectric switch. Alternatively, the control valve 6 can also adopt a structure that can control the falling of seeds in the prior art, which will not be described in detail here.

[0031] A flexible connecting pipe 7 is connected to the lower end of the connection port of the storage box 5, and the sowing device 3 is used to sow seeds. The sowing device 3 needs to move up and down during the sowing process, and the flexible connecting pipe 7 allows the sowing device 3 to make flexible movements to achieve seed sowing.

[0032] Reference Figure 2As shown, the experimental seeder has a trolley-like structure, including a body 9 and a wheel assembly 10. The body 9 serves as the platform for the experimental seeder, and the wheel assembly 10 consists of tracked wheels installed on the lower part of the body 9. The tracked structure helps maintain the stability of the equipment. The body 9 also houses components such as a controller, power supply, and motor. The motor controls the movement of the tracked wheels, and the controller further controls the movement of the trolley. The specific control structure is existing technology and will not be described in detail here. The support frame 1 is fixedly installed on the body 9, allowing the seeding device 3 within the equipment to be mounted on the body 9.

[0033] Reference Figure 1 , Figure 4 As shown, the seeding device 3 includes a seeding tube 13, the upper end of which is connected to the lower end of a flexible connecting tube 7. The seeding device 3 also includes a conical member 140, which is installed at the lower end of the seeding tube 13. The conical member 140 gradually tapers from top to bottom and has a pointed lower end, which can be inserted into the soil.

[0034] The conical component 140 is divided into two halves, specifically half-cone cylinder one 14 and half-cone cylinder two 15, which together form a conical structure. Half-cone cylinder one 14 is fixedly connected to the lower end of the seeding tube 13, and its upper contour is slightly larger. The inner wall of half-cone cylinder one 14 is welded and fixed to the outer periphery of the lower end of the seeding tube 13. The upper part of half-cone cylinder two 15 is rotatably connected to half-cone cylinder one 14 via a pivot 141, allowing half-cone cylinder two 15 to rotate relative to half-cone cylinder one 14. During rotation, half-cone cylinder two 15 allows the lower end of the conical component 140 to open and close. A spring 31 is provided on the outside of the conical member 140. The spring 31 can apply an elastic force to the first half-cone 14 and the second half-cone 15 to close together, so that the first half-cone 14 and the second half-cone 15 can close together in their natural state to form a cone-shaped structure at the lower end, so as to be inserted into the ground.

[0035] After the lower end of the conical part 140 is inserted into the soil, the second half-cone 15 and the first half-cone 14 rotate relative to each other, thereby creating an opening at the lower end. At the same time, the soil in the soil is pushed to both sides, creating a space for sowing in the soil. Seeds fall from the sowing tube 13, thereby sowing seeds into the soil.

[0036] Reference Figure 3 As shown, the experimental seeder also has a camera 8, which is mounted on the fixed frame 2. The camera 8 can acquire visual information of the land. The camera 8 can be a product of existing technology, which will not be described in detail here.

[0037] The sowing device 3 is installed at the front end of the vehicle body 9. A telescopic rod 11 and a pressure roller 12 are installed at the rear end of the vehicle body 9. The telescopic rod 11 is located at the rear end of the vehicle body 9 and is installed at an angle downwards. The lower end of the telescopic rod 11 can extend and retract; specifically, a telescopic rod 11 with elasticity can be used. The pressure roller 12 is installed at the lower end of the telescopic rod 11 and can press against the soil. The soil surface has a certain elastic pressure, allowing the pressure roller 12 to roll and compact the sown soil, covering part of the soil on the seed surface.

[0038] Reference Figure 1 , Figure 4 As shown, a slide block 4 is fixedly connected to the outside of the seeding tube 13. The slide block 4 is slidably connected to the support frame 1 and can slide up and down for adjustment. A lifting drive 17 is installed between the slide block 4 and the support frame 1. The lifting drive 17 can drive the slide block 4 and the seeding tube 13 to rise and fall, so that the tapered part 140 at the lower end of the seeding tube 13 can be inserted into the soil to realize the seeding action.

[0039] Reference Figure 4 , Figure 5 As shown, the lower end of the seeding tube 13 is located on the inner circumference of the first semi-cone 14 and the second semi-cone 15. An opening 16 is formed between the upper inner circumferential wall of the second semi-cone 15 and the outer circumferential wall of the seeding tube 13. An actuator 17 is fixedly connected to the outside of the seeding tube 13. A drive rod 18 is provided at the lower part of the actuator 17. The drive rod 18 can be adjusted up and down. The lower end of the drive rod 18 extends into the interior of the conical member 140 through the opening 16 and can abut against the inner wall of the second semi-cone 15. During the downward movement of the drive rod 18, the lower end of the drive rod 18 can abut against the inner wall of the second semi-cone 15, pushing the second semi-cone 15 to open relative to the first semi-cone 14.

[0040] Specifically, the lower end of the second semi-conical cylinder 15 is inclined towards the first semi-conical cylinder 14 and is inclined relative to the drive rod 18, so that when the lower end of the drive rod 18 extends downward, it can make a pressing contact with the second semi-conical cylinder 15. In order to improve the smoothness of linkage, a guide wheel 21 is installed at the lower end of the drive rod 18. The guide wheel 21 abuts against the inner side of the second semi-conical cylinder 15, which can form a rolling action and reduce friction during linkage.

[0041] Reference Figure 5 As shown, the lower end of the drive rod 18 is fixedly connected to a first bend 19 and a second bend 20. The first bend 19 and the second bend 20 are connected to the lower part of the drive rod 18, forming a hook-like structure. The first bend 19 extends toward the semi-conical cylinder 14, and the second bend 20 is fixedly connected to the side of the first bend 19 near the inner wall of the semi-conical cylinder 14. The second bend 20 extends in the vertical direction.

[0042] The second bend 20 is located near the inner wall of the first semi-cone 14. A guide wheel 22 is rotatably connected to the second bend 20. The guide wheel 22 abuts against the inner side of the first semi-cone 14, creating two pressure contact points between the first semi-cone 14 and the second semi-cone 15. When the drive rod 18 moves downward, the guide wheel 21 and the guide wheel 22 apply an opening force to the first semi-cone 14 and the second semi-cone 15. The load is transferred through the middle bend 19, thereby providing a stable expansion force to the first semi-cone 14 and the second semi-cone 15 over time, improving the stability of soil expansion and facilitating the formation of a seeding opening in the soil. As the drive rod 18 moves downward, the contact points between the drive rod 18, the second bending part 20, and the first and second half-cones 14 and 15 gradually move downward. The distance between the contact point and the pivot 141 of the second half-cone 15 gradually increases, making the second half-cone 15 easier to open. This compensates for the resistance when the second half-cone 15 opens relative to the first half-cone 14, and makes it easier for the lower end of the cone 140 to expand, facilitating seed placement.

[0043] Furthermore, a plug 23 is provided at the lower end of the seeding tube 13. The outline of the plug 23 is slightly smaller than the lower diameter of the seeding tube 13, and part of the plug 23 extends into the seeding tube 13. The lower part of the plug 23 is fixedly connected to the second bend 20, and the plug 23 can move up and down synchronously with the second bend 20.

[0044] An inclined surface 24 is formed on the upper part of the seeding tube 13, and an extension tube 25 is fixedly connected to the upper part of the seeding tube 13. The outer periphery of the extension tube 25 is adapted to the outer periphery of the plug 23. A notch 26 is provided on the extension tube at the lowest point of the inclined surface 24, allowing seeds to fall. A flared mouth 27 is provided at the upper end of the extension tube, gradually widening upwards and adapting to the inner diameter of the seeding tube 13. Seeds falling from the seeding tube 13 will fall into the extension tube 25 and onto the inclined surface 24 on the upper part of the plug 23. Seeds on the inclined surface 24 can fall through the notch 26 to achieve seed sowing.

[0045] The seeding tube 13 moves downward, and the conical part 140 at the lower end of the seeding tube 13 is inserted into the soil to a certain depth, so that the lower part of the conical part 140 extends into the soil for a certain length. At this time, the drive rod 18 is in a relatively high position, and most of the upper part of the plug 23 is located at the lower part of the seeding tube 13. The plug 23 seals the lower part of the seeding tube 13, and the seeds are held on the inclined surface 24 of the upper part of the plug 23.

[0046] Then, the driver 17 drives the drive rod 18 to move downwards. The drive rod 18 pushes the semi-conical tube 15 downwards to open the flare. At the same time, the plug 23 moves downwards in conjunction with the drive rod 18 until the inclined surface 24 on the upper part of the plug 23 moves to the lower end of the seeding tube 13. The seeds can then fall from the inclined surface 24 into the conical part 140 and then fall into the soil through the opening at the lower end of the conical part 140, thus realizing seed dispensing. By sealing the lower end of the seeding tube 13 with the plug 23, the lower end of the gravity tube can be prevented from entering the soil, avoiding the impact of blockage. During the downward extension and retraction of the drive rod 18, it can clear and remove mud from the lower end of the seeding tube 13. At the same time, the drive rod 18, the first bend 19 and the second bend 20 are located in the first half cone 14 and the second half cone 15, and can produce up and down lifting movements, which can block the first half cone 14 and the second half cone 15. During the movement, it can squeeze and break up the soil that may cause blockage, so that it is not easy for the end cap 23 to be blocked between the first half cone 14 and the second half cone 15.

[0047] Reference Figure 1 , Figure 2 and Figure 5 As shown, a connecting block 32 is fixedly connected to the outside of the second semi-conical cylinder 15, and a connecting block 33 is fixedly connected to the outside of the plug 23. A vertically oriented groove 34 is provided on the outside of the first semi-conical cylinder 14. The connecting block 33 is located within the groove 34 and extends through the groove 34 to the outside of the first semi-conical cylinder 14. A spring 31, a tension spring, connects the first connecting block 32 and the second connecting block 33. The spring 31 applies a relatively close elastic force to the first connecting block 32 and the second connecting block 33, thereby applying a closing force to the second semi-conical cylinder 15. Specifically, the height of connecting block 2 33 is higher than that of connecting block 1 32. When the drive rod 18 pushes the semi-conical cylinder 2 15 to open, the plug 23 will move downward with the drive rod 18, and the connecting block 2 33 on the plug 23 will also move downward with the plug 23, so that the distance between connecting block 2 33 and connecting block 1 32 is closer, thereby gradually reducing the tension on the spring 31, thus reducing the resistance encountered when the semi-conical cylinder 2 15 opens, and thus making the opening action of the semi-conical cylinder 1 14 and the semi-conical cylinder 2 15 at the lower end smoother, which is conducive to the seed sowing and placement operation.

[0048] Furthermore, referring to Figure 6As shown, two through holes 28 are formed on the side wall of the semi-conical cylinder 14, one located near the upper half of the semi-conical cylinder 14 and the other located in the lower half of the semi-conical cylinder 14. An annular belt 29 is provided between the two through holes 28. The annular belt 29 has a ring-shaped structure and passes through the two through holes 28. The upper inner part of the annular belt 29 is close to the edge of the bent part 19 and is connected and fixed to the outer side of the annular belt 29 to form a connecting part 30. This allows the bent part 19 to drive the annular belt 29 to move during its up-and-down movement, and the annular belt 29 will move in a pulling motion between the two through holes 28.

[0049] An annular belt 29 is also provided at the second semi-conical cylinder 15, and its arrangement is roughly the same as that at the first semi-conical cylinder 14. Specifically, two through holes 28 are opened on the side wall of the second semi-conical cylinder 15, one located near the upper half of the second semi-conical cylinder 15 and the other located in the lower half of the second semi-conical cylinder 15. An annular belt 29 is provided between the two through holes 28. The annular belt 29 has a ring-shaped structure and passes through the two through holes 28. The upper inner part of the annular belt 29 is close to the edge of the first bending part 19, and the annular belt 29 is connected and fixed to the outer side of the first bending part 19 to form a connecting part 30. This allows the first bending part 19 to drive the annular belt 29 to move during its up-and-down movement, and the annular belt 29 will move in a pulling motion between the two through holes 28.

[0050] During the lifting and lowering process of the drive rod 18, the drive rod 18 will drive the bending part 19 to lift and lower. The bending part 19 is connected to the annular belts 29 on both sides through the connecting part 30, thereby enabling the annular belts 29 to also achieve annular motion. The part of the annular belt 29 located inside the semi-cone 14 and the semi-cone 2 15 will make contact friction with the inner side wall of the semi-cone. Even if soil adheres to the inner side wall, the friction of the annular belt 29 will cut the adhered soil, breaking the large pieces of soil entering the semi-cone into smaller pieces, preventing them from adhering to the inner wall. Then the soil will fall back down, avoiding blockage of the internal space of the cone-shaped part 140.

The seeder uses a trolley structure as a platform, is able to move in the field, and can sow seeds in the field in conjunction with the seeding device 3.

[0053] The vehicle body 9 uses tracked wheel assemblies 10 with shock absorbers, which increases its passability and makes it move more smoothly and stably on uneven soil in the field. The wheel assemblies 10 are driven by electric motors. The electric system is lighter than a fuel engine. In addition, solar photovoltaic panels (not shown in the figure) can be installed on the vehicle body 9 for charging, increasing the driving range.

[0054] In addition, the test system is equipped with data sensors such as infrared sensors, ultrasonic sensors, and cameras 8 on its vehicle body 9.
