Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for seed control group trial planting, specifically to a modular automatic seed supply device and method. Background Technology

[0002] Before seeds are cultivated and put into use, a control group experiment needs to be conducted in different plots to test seed performance under different variable conditions using the controlled variable method, thereby obtaining the required experimental parameters. Currently, there is a control experiment where, while keeping all other conditions the same, only the number of seeds per plant is changed to achieve a reasonable sowing number per plant. Existing control experiments use manual sowing, resulting in a long sowing cycle and inaccurate data due to the influence of seed germination period. Therefore, an automated sowing device is designed to sow the control group as simultaneously as possible to achieve similar germination cycles among the seeds. For this purpose, a corresponding feeding device needs to be developed for the automated sowing equipment. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a modular automatic seed supply device and method. This device and method employ a multi-stage feeding structure and are equipped with an adjustable temporary storage structure, thereby enabling multi-stage and multi-cell seed supply and allowing the feeding amount of each stage to be preset according to experimental variables.

[0005] Preferably, the material guiding mechanism comprises: The guide tube is fixedly mounted on the frame, and its left end is inclined downward. The feed hopper is fixedly installed on the left end of the guide pipe; The discharge hopper is fixedly installed on the right port of the guide pipe, and the lower port of the discharge hopper is fixedly connected to the upper port of the adjacent feed hopper on the right. The spiral roller is inserted into the feed tube, and the right end shaft of the spiral roller is screwed onto the right side wall of the discharge hopper via a bearing. The drive motor is fixedly mounted on the outer side wall of the discharge hopper, and the output shaft of the drive motor is connected to the right end of the spiral roller via a spline.

[0006] Preferably, the feeding mechanism comprises: The feeding pipe is connected to the guide pipe, and the feeding pipe and the guide pipe are connected by bearings. A connecting sleeve, which is movably fitted onto the feeding pipe; The discharge pipe is fixed to the lower side wall of the connecting sleeve. The feeding pipe has a feeding port, which is connected to the upper end of the discharge pipe. A rotary drive assembly is disposed on the outer wall of the guide tube and is configured in conjunction with the feeding tube.

[0007] Preferably, the rotary drive assembly comprises: A spiral guide rod is wound around the outside of the connecting sleeve, and the left and right ends of the spiral guide rod are respectively fixed on the outer walls of the left and right ends of the feeding pipe. A stepping hydraulic rod, wherein the stepping hydraulic rod is fixedly installed on the outer side wall of the guide tube; The guide seat is fixedly mounted on the output shaft of the stepping hydraulic rod, and is movably sleeved on the helical guide rod.

[0008] Preferably, the discharge mechanism comprises: The discharge chute is fixedly installed on the lower end of the discharge pipe; An adjusting cover is spun onto the upper side wall of the discharge chute via a rotating shaft, and the adjusting cover covers the side opening of the discharge chute. An opening and closing servo motor is fixedly installed on the side wall of the discharge chute, and the output shaft of the opening and closing servo motor is fixedly installed on the rotating shaft of the adjusting cover. Mounting base, the mounting base is fixedly installed on the lower inner side wall of the adjustment cover; A threaded rod, wherein the threaded rod is threadedly inserted into the mounting base; A blocking piston is screwed onto the upper end of a threaded rod via a bearing, and the blocking piston is clamped between the discharge chute and the adjusting cover.

[0009] Preferably, the sealing piston is positioned at one end of its side inside the discharge chute, tilted downwards.

[0010] Preferably, a waste discharge port is provided on the left end wall of the guide pipe, and a cover plate is provided on the waste discharge port. The upper side of the cover plate is screwed onto the guide pipe through a rotating shaft. A waste discharge servo motor is fixedly provided on the left end wall of the guide pipe, and the output shaft of the waste discharge servo motor is fixedly provided on the rotating shaft of the cover plate.

[0011] The method of using this invention is as follows: Based on the number of control group plots, select the corresponding number of this device and fix it to the external mounting structure using a frame. Connect the discharge trough to the corresponding sowing unit. Then, connect the discharge hopper of one guide pipe to the infeed hopper of the adjacent guide pipe. This allows seeds to be added from the infeed hopper of the first guide pipe and discharged from the discharge hopper of the last guide pipe. After installation, cover the discharge trough with an adjusting cover, so that one side of the sealing piston extends and abuts against the inner wall of the discharge trough. Next, adjust the height of the sealing piston according to the number of seeds needed for a single sowing in the community. Rotate the threaded rod to move it on the mounting base, thereby raising and lowering the sealing piston. This adjusts the closing of the discharge chute and the position of the adjusting hood above the sealing piston, thus adjusting the amount of seeds entering the filling space. Then, start the drive motor to rotate the spiral roller, loading seeds from the feed hopper at the beginning. The seeds enter the feed pipe at the beginning and are propelled forward by the spiral roller within it. Finally, the seeds exit through the guide pipe at the beginning. The hopper discharges the seeds into the next-level feed pipe, and so on. As the seeds advance through the feed pipe and pass the feed inlet of the feeding pipe, they are discharged from the feeding pipe into the discharge pipe and further fall into the closed loading space formed by the discharge chute, adjusting cover, and sealing piston, until the loading space and the inner cavity of the discharge pipe are filled. Excess seeds in the feed pipe then move to the next-level feed pipe, and a large number of seeds are discharged into the discharge hopper at the tail end. Once the loading space corresponding to each plot is full, the stepping hydraulic rod pushes the guide seat, which moves on the spiral guide rod. The material slides, causing the feeding pipe to rotate via the spiral guide rod. This causes the feeding port on the feeding pipe to shift away from the upper port of the discharge pipe. The feeding port is then blocked by the connecting sleeve, and the upper port of the discharge pipe is blocked by the feeding pipe. Next, the adjusting cover is opened by the opening and closing servo motor, allowing the seeds placed in the loading space to fall out of the open discharge trough. When cleaning the guide pipe, the cover is opened by the waste discharge servo motor, and the drive motor rotates in the opposite direction, causing the spiral roller to rotate in the opposite direction. The spiral roller pushes the material in the guide pipe toward the waste discharge port.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This device can achieve the docking of multiple sections of the guide pipe by setting an inclined guide pipe with a feed hopper and a discharge hopper. A feeding pipe is set on the guide pipe and a discharge pipe is set through a connecting sleeve, thereby realizing the step-by-step feeding of multiple sections of the feeding pipe. 2. This device is equipped with a discharge chute and an adjusting cover on the feeding pipe, and a height-adjustable sealing piston is installed on the adjusting cover, so as to adjust the amount of seed material loaded into the discharge pipe and discharge chute at one time, thereby realizing the quantitative material feeding of this device.

The lower end of the side wall of the feed hopper 2-2 is provided with a waste discharge port 6, and the cover plate 7 is placed over the waste discharge port 6. Waste discharge servo motor 8 is fixedly installed on the outer side wall of the feed hopper 2-2, and the output shaft of the waste discharge servo motor 8 is fixedly installed on the rotating shaft of the cover plate 7. Feeding mechanism 3 includes: The feeding pipe 3-1 is connected through the guide pipe 2-1, and the feeding pipe 3-1 and the guide pipe 2-1 are connected by bearings. Connecting sleeve 3-3 is movably sleeved on feeding pipe 3-1; The discharge pipe 3-4 is fixed to the lower side wall of the connecting sleeve 3-3. The feeding pipe 3-1 has a feeding port 3-2, and the feeding port 3-2 is connected to the upper end of the discharge pipe 3-4. The rotary drive assembly 4 is disposed on the outer wall of the guide tube 2-1 and is configured in conjunction with the feeding tube 3-1. Rotary drive component 4 includes: The spiral guide rod 4-1 is wound around the outside of the connecting sleeve 3-3, and the left and right ends of the spiral guide rod 4-1 are respectively fixed on the outer side walls of the left and right ends of the feeding pipe 3-1. Stepping hydraulic rod 4-2, the stepping hydraulic rod 4-2 is fixedly installed on the outer side wall of the guide tube 2-1; Guide seat 4-3 is fixedly mounted on the output shaft of stepping hydraulic rod 4-2, and guide seat 4-3 is movably sleeved on helical guide rod 4-1; The discharge mechanism 5 includes: The discharge chute 5-1 is fixedly installed on the lower end of the discharge pipe 3-4; Adjustment cover 5-2 is spun onto the upper side wall of discharge trough 5-1 via a rotating shaft, and the adjustment cover 5-2 covers the side opening of discharge trough 5-1. The opening and closing servo motor 5-3 is fixedly installed on the side wall of the discharge chute 5-1, and the output shaft of the opening and closing servo motor 5-3 is fixedly installed on the rotating shaft of the adjusting cover 5-2. Mounting base 5-4, wherein the mounting base 5-4 is fixedly installed on the lower inner side wall of the adjusting cover 5-2; The threaded rod 5-5 is threadedly threaded onto the mounting base 5-4; The sealing piston 5-6 is screwed onto the upper end of the threaded rod 5-5 via a bearing, and the sealing piston 5-6 is clamped between the discharge chute 5-1 and the adjusting cover 5-2. The blocking piston 5-6 is inclined downward at one end inside the discharge chute 5-1. When the regulating cover 5-2 is closed, a space for loading materials is formed by the discharge chute 5-1, the regulating cover 5-2, and the blocking piston 5-6. The volume of this space can be adjusted by adjusting the height of the blocking piston 5-6.

[0021] When using this device, take the corresponding number of devices according to the number of control group plots, and fix the device to the external mounting structure through the frame. Connect the discharge trough 5-1 to the sowing unit. Then, connect the discharge hopper 2-3 of one guide pipe 2-1 to the feed hopper 2-2 of the adjacent guide pipe 2-1, so that seeds are added from the feed hopper 2-2 on the first guide pipe 2-1 and the excess seeds are discharged from the discharge hopper 2-3 on the last guide pipe 2-1. After the device is installed, the adjusting cover 5-2 covers the discharge trough 5-1, so that one side of the blocking piston 5-6 extends and abuts against the inner wall of the discharge trough 5-1. Next, adjust the height of the sealing piston 5-6 according to the number of seeds needed for a single sowing in the community. Rotate the threaded rod 5-5 to move it on the mounting base 5-4, thereby causing the sealing piston 5-6 to rise and fall. This adjusts the filling space above the closed discharge chute 5-1 and adjusting cover 5-2 via the sealing piston 5-6, thus adjusting the number of seeds entering the filling space. Then, start the drive motor 2-5 to rotate the spiral roller 2-4, loading seeds into the feed hopper 2-2 at the beginning. The seeds enter the feed pipe 3-1 at the beginning and are propelled by the spiral roller 2-4. The seeds then pass through the discharge hopper 2-2 of the feed pipe 2-1 at the beginning. -3 The seeds are discharged into the next-level guide pipe 2-1, and so on; when the seeds advance in the guide pipe 2-1 and pass through the feed port 3-2 of the feed pipe 3-1, the seeds are discharged from the feed pipe 3-1 into the discharge pipe 3-4 and further fall into the closed loading space formed by the discharge trough 5-1, the adjusting cover 5-2, and the sealing piston 5-6, until the loading space and the inner cavity of the discharge pipe 3-4 are filled. Thus, the excess seeds in the guide pipe 2-1 move to the next-level guide pipe 2-1, and after a large number of seeds are discharged into the discharge hopper 2-3 at the tail end, that is, the loading space corresponding to each plot is filled, then the guide seat 4-3 is pushed by the stepping hydraulic rod 4-2, and the guide seat 4-3 moves on the spiral guide rod 4-1. The material slides, causing the feeding pipe 3-1 to rotate via the spiral guide rod 4-1. This causes the feeding port 3-2 on the feeding pipe 3-1 to shift away from the upper port of the discharge pipe 3-4. The feeding port 3-2 is then blocked by the connecting sleeve 3-3, and the upper port of the discharge pipe 3-4 is blocked by the feeding pipe 3-1. Then, the adjusting cover 5-2 is opened by the opening and closing servo motor 5-3, allowing the seeds placed in the loading space to fall out of the open discharge trough 5-1. When cleaning the guide pipe 2-1, the cover plate 7 is opened by the waste discharge servo motor 8, and the drive motor 2-5 rotates in the opposite direction, thereby driving the spiral roller 2-4 to rotate in the opposite direction. The spiral roller 2-4 pushes the material in the guide pipe toward the waste discharge port 6 for discharge.

This device is equipped with an inclined guide pipe 2-1 with a feed hopper 2-2 and a discharge hopper 2-3, which enables the docking of multiple guide pipes 2-1. A feeding pipe 3-1 is set on the guide pipe 2-1, and a discharge pipe 3-4 is set through a connecting sleeve 3-3, thereby realizing the step-by-step feeding of multiple feeding pipes 3-1. 2.

Then, connect the adjacent guide pipes (2-1) through the discharge hopper (2-3) of one guide pipe (2-1) to the feed hopper (2-2) on the adjacent guide pipe (2-1), so that the seeds are added from the feed hopper (2-2) on the first guide pipe (2-1) and the excess seeds are sent out from the discharge hopper (2-3) on the tail guide pipe (2-1). After the device is installed, the adjusting cover (5-2) covers the discharge trough (5-1), so that one side of the blocking piston (5-6) extends and abuts against the inner wall of the discharge trough (5-1). The height of the sealing piston (5-6) is adjusted according to the number of seeds to be sown at one time in the community. The threaded rod (5-5) is rotated to move on the mounting base (5-4), thereby driving the sealing piston (5-6) to move up and down. This allows the sealing piston (5-6) to adjust the closed discharge chute (5-1) and the adjusting cover (5-2) above the sealing piston (5-6), thus adjusting the number of seeds entering the discharge space. Then, the drive motor (2-5) is started to drive the spiral roller (2-4) to rotate, and the seeds are loaded from the feed hopper (2-2) at the first end. The seeds enter the feed pipe (3-1) at the first end and are pushed forward by the spiral roller (2-4) inside. The seeds are discharged through the discharge hopper (2-3) of the guide pipe (2-1) at the first end and enter the next guide pipe (2-1), and so on.As the seeds advance through the feed pipe (2-1) and pass through the feed port (3-2) of the feed pipe (3-1), they are discharged from the feed pipe (3-1) into the discharge pipe (3-4) and further fall into the closed loading space formed by the discharge trough (5-1), the adjusting cover (5-2), and the sealing piston (5-6) until the loading space and the inner cavity of the discharge pipe (3-4) are filled. Excess seeds in the feed pipe (2-1) then move to the next feed pipe (2-1) and are discharged in large quantities into the discharge hopper (2-3) at the tail end. This fills the loading space corresponding to each plot. Then, the stepping hydraulic rod (4-2) pushes the guide seat (4-3), which slides on the spiral guide rod (4-1). This allows the seeds to pass through the spiral guide rod (4-1) and into the discharge space. -1) The feeding pipe (3-1) is rotated, causing the feeding port (3-2) on the feeding pipe (3-1) to shift away from the upper port of the discharge pipe (3-4).
