Description

Technical Field

[0001] The invention relates to the technical field of locators, in particular to a portable corn sowing locator. Background Art

[0002] In the process of manual corn sowing, in order to further improve the accuracy of corn sowing and help farmers determine the precise row spacing and plant spacing, farmers often use portable corn seeders to achieve accurate positioning of sowing row spacing and plant spacing, thereby ensuring that the sowing position of each seed meets the predetermined standards, thereby reducing uneven sowing caused by human errors.

[0003] The existing manual and convenient corn sowing locator used by farmers can accurately locate the plant spacing and row spacing of corn sowing. However, during the corn sowing process, when the soil is relatively dry, the seeds need to be buried slightly deeper to help them obtain more stable moisture. When the soil is relatively moist, moderately shallow burial can increase the germination speed and prevent the seeds from rotting due to lack of oxygen. The existing corn sowing locator cannot adjust the burial depth of corn seeds according to the specific conditions of the soil. Inappropriate depth inhibits the growth of the corn seed root system, increases agricultural risks, and thus reduces the practicality of the portable corn sowing locator.

[0004] Therefore, we propose a convenient corn sowing locator to solve the above problems. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-3The present invention provides a technical solution: a portable corn sowing locator, comprising a seed box 1 and a drainage box 4, a compression frame 10 is fixed to the outer surface of the seed box 1, a damping shaft 11 is arranged between the opposite inner walls of the compression frame 10, a telescopic plate 12 for measuring the corn spacing is arranged on the outer surface of the damping shaft 11, a positioning assembly 8 is arranged at the bottom of the drainage box 4, the positioning assembly 8 comprises a duckbill hopper 801, a humidity sensor 802 is arranged near the bottom of the outer surface of one side of the duckbill hopper 801, an electric push rod 803 is arranged on the inner top surface of the duckbill hopper 801, a limit plate 804 is fixedly installed at the bottom end of the electric push rod 803, and the limit plate 804 A movable plate 805 is rotatably connected internally, a rotating rod 806 is fixedly installed on the outer surface of one side of the movable plate 805, a base 807 is fixedly installed near the top on the outer surface of the duckbill feeding hopper 801 on the same side as the humidity sensor 802 by screws, a connecting shaft 808 is rotatably connected internally to the base 807, a driving gear 809 is fixedly sleeved on the outer surface of the connecting shaft 808, a positioning block 810 is fixedly connected to one end of the connecting shaft 808, an automatic feeding assembly 9 for corn sowing is arranged on the top of the duckbill feeding hopper 801, the automatic feeding assembly 9 includes a driven gear 904, and a driving shaft 903 is fixed to the outer surface of the driven gear 904.

[0033] In this embodiment, when it is necessary to use the corn sowing positioner to sow corn seeds, first pull up the protective cover 3, open the seed box 1, and put the corn seeds prepared in advance into the seed box 1, so that the corn seeds slide down along the seed box 1 under the action of their own gravity to the inside of the drainage box 4, wherein, as Figure 3 As shown, the drainage box 4 is provided with an arc block inside, the purpose of which is to facilitate the downward flow of corn seeds. After the corn seeds are placed, the sowing positioner is moved to the position where the sowing is required, and the telescopic plate 12 is manually rotated upward until the telescopic plate 12 is perpendicular to the seed box 1, and then the telescopic plate 12 is stretched outward until the length of the telescopic plate 12 reaches the required spacing value between every two corn plants. Figure 2 As shown, the outer surface of the telescopic plate 12 is provided with a scale, which is convenient for farmers to manually adjust its length. The brand of the telescopic plate 12 is: Cobondi, and the item number is KBD-hook distance ruler. In addition, through the setting of the damping shaft 11, the telescopic plate 12 is effectively limited. The damping shaft 11 introduces resistance to slow down the vibration and impact of the moving object. It uses the friction generated by the solid material to absorb energy, thereby reducing the amplitude of the vibration. When the damping shaft 11 is subjected to external vibration or impact, the damping material will generate resistance due to its inherent physical properties. This resistance will consume energy in the form of heat, thereby reducing the vibration amplitude and frequency, and play a role in positioning the telescopic plate 12. By extending and scaling the telescopic plate 12, the volume of the telescopic plate 12 is reduced, thereby further increasing the portability of corn sowing positioning.

[0034] like Figure 1-Figure 9 As shown, a portable corn sowing positioner comprises a seed box 1 and a drainage box 4, a compression frame 10 is fixed to the outer surface of the seed box 1, a damping shaft 11 is arranged between the opposite inner walls of the compression frame 10, a telescopic plate 12 for measuring the corn plant spacing is arranged on the outer surface of the damping shaft 11, a positioning assembly 8 is arranged at the bottom of the drainage box 4, the positioning assembly 8 comprises a duckbill hopper 801, a humidity sensor 802 is arranged near the bottom of the outer surface of one side of the duckbill hopper 801, an electric push rod 803 is arranged on the inner top surface of the duckbill hopper 801, a limit plate 804 is fixedly installed at the bottom end of the electric push rod 803, and the inner part of the limit plate 804 A movable plate 805 is rotatably connected, a rotating rod 806 is fixedly installed on the outer surface of one side of the movable plate 805, a base 807 is fixedly installed near the top on the outer surface of the duckbill feeding hopper 801 and the humidity sensor 802 by screws, a connecting shaft 808 is rotatably connected inside the base 807, a driving gear 809 is fixedly sleeved on the outer surface of the connecting shaft 808, a positioning block 810 is fixedly connected to one end of the connecting shaft 808, an automatic feeding assembly 9 for corn sowing is arranged on the top of the duckbill feeding hopper 801, and the automatic feeding assembly 9 includes a driven gear 904, and a driving shaft is fixed on the outer surface of the driven gear 904 903, a mounting plate 901 is fixed on the top of the duckbill hopper 801, a speed changer 902 is arranged on the top of the mounting plate 901, an input end of the speed changer 902 is fixedly connected to one end of the drive shaft 903, an output end of the speed changer 902 is fixedly connected to an output shaft 905, a rotating column 906 is fixed to one end of the output shaft 905, an outer surface of the rotating column 906 is provided with two collecting grooves 907 for placing corn seeds, and an outer surface of the other side of the limiting plate 804 is provided with two mounting grooves 811, rollers 812 are arranged between the opposite inner walls of the two mounting grooves 811, and the outer surfaces of the two rollers 812 are both connected to the duckbill hopper The inner wall of the hopper 801 is in contact with the top of the drainage box 4 and is fixedly connected to the bottom of the seed box 1. The outer surface of the limit plate 804 is slidably connected to the inner wall of the duckbill feeding hopper 801. One end of the connecting shaft 808 is movable through the outside of the base 807. One end of the rotating rod 806 is movable through the outside of the positioning block 810. The outer surface of the driving gear 809 is meshed with the outer surface of the driven gear 904. The two ends of the rotating column 906 are movable through the opposite outsides of the drainage box 4 respectively. A depth detector 6 is set near the bottom of the outer surface of the other side of the duckbill feeding hopper 801, and a controller 7 is set near the top of the outer surface of the seed box 1.

[0035] In this embodiment, the corn seeds continue to slide downward along the drainage box 4 and enter into one of the collecting grooves 907, wherein the inner diameter of the narrowest part of the drainage box 4 matches the outer diameter of the rotating column 906. At this time, the depth detector 6 and the humidity sensor 802 can be started. At the same time, the farmer can press the handrail 2 downward to drive the duckbill feeding hopper 801 to move downward, thereby driving the humidity sensor 802 and the depth detector 6 to move toward the inside of the soil. When the humidity sensor 802 detects that the soil moisture at a certain depth is suitable for placing corn seeds, it transmits a signal to the controller 7, wherein the humidity The sensor 802 is based on the frequency change of the oscillator. When the soil moisture changes, the moisture in the soil will affect the frequency of the oscillator. The sensor infers the soil moisture by measuring the change in frequency. It can be used to monitor the dynamic moisture of the soil and has a good response time. The controller 7 receives the signal and starts the electric push rod 803 to extend it, driving the limit plate 804 to move downward until the bottom of the limit plate 804 moves to a position in contact with the soil surface, thereby preventing the duckbill hopper 801 from continuing to move downward. During the downward movement of the limit plate 804, the bottom end of the rotating rod 806 is driven downward. Figure 7As shown, the connection between the limit plate 804 and the movable plate 805 is a T-shaped rotation connection, and the connection between the base 807 and the connecting shaft 808 is also a T-shaped rotation connection. The bottom end of the rotating rod 806 moves downward so that the positioning block 810 is squeezed and rotated, thereby driving the connecting shaft 808 to rotate, thereby rotating the active gear 809, and the active gear 809 drives the driven gear 904 to rotate, thereby driving the drive shaft 903 to rotate. At this time, the depth detector 6 detects the depth of the duckbill hopper 801. The depth detector 6 uses the weak gravity waves of the ground and the objects in the soil to affect the gravity field of the ground. These changes are detected by a high-precision gravity sensor, and the position and depth of the buried object can be inferred. The depth detector 6 transmits the detected signal to the controller 7, and the controller 7 transmits the signal to the speed changer 902 through analysis and calculation. The speed changer 902 changes the output speed by switching different gear combinations, and adopts an intelligent control system to automatically adjust the speed according to the load, speed and other state feedback to optimize the equipment performance and save energy. The speed changer 902 adjusts the speed of the driving shaft 903 according to the received signal, and then outputs it through the output shaft 905. The output shaft 905 drives the collection tank 907 with the corn seeds to rotate 180 degrees, so that the positions of the two collection tanks 907 are interchanged, and then the collection tank 907 filled with corn seeds is rotated to the bottom with the opening facing downward, so that the corn seeds move to the soil along the discharge port in the duckbill hopper 801 under the action of their own gravity, and the sowing of the corn seeds is completed. When the duckbill hopper 801 moves to the ground After that, the electric push rod 803 is started again to drive the limit plate 804 to reset, and the speed changer 902 is started through the controller 7, so that the rotation of the connecting shaft 808 will not drive the rotating column 906 to rotate. Through the cooperation of the positioning component 8 and the automatic feeding component 9, the corn sowing positioner can automatically adjust the seed burying depth according to the soil moisture, so that the corn seeds can grow at the most suitable depth, increase the crop yield, and solve the problem that most corn seeders in the prior art cannot bury the corn seeds according to the specific conditions of the soil, reducing the corn yield.

[0036] like Figure 1-Figure 2 and Figure 4As shown, a portable corn sowing locator comprises a seed box 1 and a drainage box 4, a compression frame 10 is fixed to the outer surface of the seed box 1, a damping shaft 11 is arranged between the opposite inner walls of the compression frame 10, a telescopic plate 12 for measuring the corn plant spacing is arranged on the outer surface of the damping shaft 11, a positioning assembly 8 is arranged at the bottom of the drainage box 4, the positioning assembly 8 comprises a duckbill hopper 801, a humidity sensor 802 is arranged on the outer surface of one side of the duckbill hopper 801 near the bottom, an electric push rod 803 is arranged on the inner top surface of the duckbill hopper 801, The bottom end of the electric push rod 803 is fixedly installed with a limit plate 804, the inner rotation of the limit plate 804 is connected to a movable plate 805, and a rotating rod 806 is fixedly installed on the outer surface of one side of the movable plate 805. The outer surface of the duckbill hopper 801 and the humidity sensor 802 on the same side is fixedly installed with a base 807 by screws near the top, and the inner rotation of the base 807 is connected to a connecting shaft 808. The outer surface of the connecting shaft 808 is fixedly sleeved with a driving gear 809, and one end of the connecting shaft 808 is fixedly connected to a positioning block 810. An automatic feeding assembly 9 for corn sowing is arranged on the top of the hopper 801, and the automatic feeding assembly 9 includes a driven gear 904, and a driving shaft 903 is fixed to the outer surface of the driven gear 904. A handrail 2 is fixed to the top of the seed box 1, and a protective cover 3 is movably installed between the opposite inner walls of the seed box 1 near the top. Support assemblies 5 are arranged on the opposite outer surfaces of the seed box 1, and the two support assemblies 5 include support columns 502. The bottom ends of the two support columns 502 are fixed with a chassis 505 for increasing the support area. A slide groove 501 is provided on the surface, and the outer surfaces of the two support columns 502 are slidably connected to the inner walls of the two slide grooves 501 respectively. Telescopic rods 503 are fixedly installed on the inner top surfaces of the two slide grooves 501. Springs 504 are arranged on the outer surfaces of the two telescopic rods 503. The bottom ends of the two telescopic rods 503 are fixedly connected to the top ends of the two support columns 502 respectively, and the top ends of the two springs 504 are fixedly connected to the inner top surfaces of the two slide grooves 501 respectively, and the bottom ends of the two springs 504 are fixedly connected to the top ends of the two support columns 502 respectively.

[0037] In this embodiment, as the duckbill hopper 801 moves downward, the two springs 504 are squeezed and shortened, thereby driving the telescopic rod 503 to shorten. After the corn is dropped, when the pressure on the handrail 2 stops, the two springs 504 will extend upward under the action of their own gravity, driving the entire corn sowing locator to move upward until the bottom of the duckbill hopper 801 is parallel to the bottom of the two chassis 505. Through the setting of the support component 5, the duckbill hopper 801 can be automatically pulled out of the soil after the corn sowing locator is sown, without the need for manual operation by farmers, thus saving manpower.

[0038] The use method and working principle of the device are as follows: when it is necessary to use the corn sowing locator to sow corn seeds, first pull up the protective cover 3 to open the seed box 1, and put the corn seeds prepared in advance into the seed box 1, so that the corn seeds slide down along the seed box 1 to the inside of the drainage box 4 under the action of their own gravity. After the corn seeds are put in, move the sowing locator to the position where they need to be sown, and manually rotate the telescopic plate 12 upward until the telescopic plate 12 is perpendicular to the seed box 1, and then stretch the telescopic plate 12 outward until the length of the telescopic plate 12 reaches the required spacing value between every two corn plants. The corn seeds continue to slide downward along the drainage box 4 and enter the inside of one of the collection slots 907, and start the depth detector 6 and the humidity sensor 80. 2. At the same time, the farmer can press the handrail 2 downward to drive the duckbill hopper 801 to move downward. When the duckbill hopper 801 moves downward, the two springs 504 are squeezed and shortened, thereby driving the telescopic rod 503 to shorten, thereby driving the humidity sensor 802 and the depth detector 6 to move toward the inside of the soil. When the humidity sensor 802 detects that the soil moisture at a certain depth is suitable for placing corn seeds, the signal is transmitted to the controller 7. The controller 7 receives the signal and starts the electric push rod 803 to extend it, driving the limit plate 804 to move downward until the bottom of the limit plate 804 moves to a position in contact with the soil surface, thereby preventing the duckbill hopper 801 from continuing to move downward. During the downward movement of the limit plate 804, the rotating rod 8 is driven 06 moves downward, and the bottom end of the rotating rod 806 moves downward so that the positioning block 810 is squeezed and rotated, thereby driving the connecting shaft 808 to rotate, so that the driving gear 809 rotates, and the driving gear 809 drives the driven gear 904 to rotate, thereby driving the driving shaft 903 to rotate. At this time, the depth detector 6 detects the depth of the duckbill hopper 801, and the depth detector 6 transmits the detected signal to the controller 7. The controller 7 transmits the signal to the speed changer 902 through analysis and calculation. The speed changer 902 adjusts the speed of the driving shaft 903 according to the received signal, and then outputs it through the output shaft 905. The output shaft 905 drives the collection tank 907 of the rotated corn seeds to rotate 180°, so that the position between the two collection tanks 907 is The positions are interchanged, so that the collecting trough 907 filled with corn seeds rotates to the lowest end with the opening facing downward, so that the corn seeds move into the soil along the discharge port in the duckbill hopper 801 under the action of their own gravity, and the sowing of the corn seeds is completed. After the corn is put in, when the pressure on the handrail 2 is stopped, the two springs 504 will extend upward under the action of their own gravity, driving the entire corn sowing positioner to move upward until the bottom of the duckbill hopper 801 is parallel to the bottom of the two chassis 505. Through the setting of the support assembly 5, the duckbill hopper 801 can be automatically pulled out of the soil after the corn sowing positioner is sown. When the duckbill hopper 801 moves to the ground, the electric push rod 803 is started again to drive the limit plate 804 to reset.At the same time, the speed changer 902 is started by the controller 7, so that the rotation of the connecting shaft 808 will not drive the rotating column 906 to rotate. Through the cooperation of the positioning component 8 and the automatic feeding component 9, the corn sowing positioner can automatically adjust the seed burying depth according to the soil moisture, so that the corn seeds can grow at the most suitable depth.

[0039] The wiring diagram of the depth detector 6, controller 7, humidity sensor 802, electric push rod 803 and speed changer 902 in the present invention is common knowledge in the field, and its working principle is a well-known technology.
