The guide plate 7 is used to guide the seeds to flow to the position between the mounting frames 4. A fixed pipe 8 is fixedly connected to the lower side of the transport cabin 1. A storage device 9 is provided inside the transport cabin 1, and the storage device 9 is used to store seeds that need to be planted. The storage device 9 is used to raise the seeds to the unloading port structure of the transport cabin 1 for unloading. The storage device 9 is used to run downward without load to the reflux port structure of the transport cabin 1 to receive the refluxed seeds. A blocking device 10 is provided between the lower side of the transport cabin 1 and the fixed pipe 8. The blocking device 10 is used to block the reflux port structure of the transport cabin 1. The blocking device 10 is triggered by the downward movement of the storage device 9 to stop the blocking state of the reflux port structure of the transport cabin 1. The blocking device 10 is reset by the upward movement of the storage device 9 to re-block the reflux port structure of the transport cabin 1, and the fixed pipe 8 is fixed with the storage device 9.

The collecting device 12 is used to collect seeds received at the inoculation device 11, and the collecting device 12 is used to release the collected seeds in a controlled manner. A diverter device 13 is provided at the periphery of the fixed tube 8, and the diverter device 13 is connected to the collecting device 12. The diverter device 13 is used to temporarily store a certain amount of seeds released by the collecting device 12. The diverter device 13 allows the seeds collected by the collecting device 12 for multiple times to be temporarily stored independently, and the diverter device 13 is used to discharge seeds to the outside.
[0037] When sowing in farmland, in order to avoid the disadvantage of low seed yield caused by collision and shearing of seeds by mechanical mechanisms due to the seeds passing through the existing seeding equipment, the automatic seeding equipment of the agricultural seeder can be used; when it is necessary to sow in farmland, the automatic seeding equipment of the agricultural seeder can be installed in the seeding area of the seeder through the external frame 2, and the seeding pipe of the seeder is connected to the diversion device 13, and the sowing water source of the seeding pipe of the seeder is connected, and the external feed pipe 3 is installed in the seed bin of the seeder and its mechanism, according to the required sowing method, such as spot sowing, hole sowing, and at the same time according to the seed diameter, the inoculation device 11 is adjusted so that the inoculation device 11 can receive a set amount of seeds and seeds of adapted diameter;Subsequently, the automatic seed discharging device of the agricultural seeder can be powered on and controlled. At this time, the seeds can be released into the storage device 9 through the seed bin of the seeder and its mechanism, and the inoculation program of the automatic seed discharging device of the agricultural seeder is started, so that the storage device 9 runs upward, and the storage device 9 will drive the seeds therein to move upward, so that the storage device 9 runs upward to the discharge port structure of the transport cabin 1. When the storage device 9 runs upward, the blocking device 10 will also move upward to block the reflux port structure of the transport cabin 1. At this time, the seeds in the storage device 9 will fall out from the discharge port structure of the transport cabin 1, and the seeds will fall between the mounting frames 4 under the guidance of the guide plate 7 and slide down on the inoculation device 11. The inoculation device 11 will receive When the set amount of seeds is received, the remaining seeds will not be received by the inoculating device 11 and will remain at the reflux port structure of the transport cabin 1 and will be blocked by the blocking device 10. At this time, the inoculating device 11 receives and fixes the set amount of seeds, and then the program will control the storage device 9 to move downward for reset, and the storage device 9 will move downward without load. When the storage device 9 moves downward to be located in the blocking device 10, the storage device 9 continues to move downward for reset, which will drive the blocking device 10 to move downward. At this time, the blocking device 10 will gradually open the reflux port structure of the transport cabin 1 until the storage device 9 is reset downward. At this time, the reflux port structure of the transport cabin 1 is completely open, and the excess seeds located at the reflux port structure of the transport cabin 1 will return to the The seeds flow into the storage device 9, at which time the storage device 9 stops running, and only a set amount of seeds are left in the inoculation device 11. During the whole process, compared with the existing seed seeding machines for quantitative seeding of seeds, the existing seed seeding machines mostly use a moving mechanical structure to directly contact the seeds, and use a mechanical method to directly separate the seeds quantitatively. When the seed seeding machine is started, the surface of the seeds is always in direct friction with the mechanical structure, resulting in the seeds being frequently collided, squeezed and sheared by the protruding parts of the mechanical structure, resulting in the seeds being damaged. Easily sowing such seeds is prone to the disadvantage of low survival rate. The seeds in the storage device 9 do not collide, be mechanically squeezed or sheared with the protruding mechanical structure during movement, and the seeds fall into the receiving When the seeding device 11 is at the seeding device 11, it is not subjected to a driving force directly acting on the surface, that is, the seeds are not directly affected by external forces. In this way, the quality of the seeds can be better preserved during the movement, and bad seeds can be avoided from being sown in the farmland, resulting in a low survival rate. After the seeding device 11 receives a certain amount of seeds, the diverter device 13 will perform a self-check, so that the vacant area at the diverter device 13 moves to below the collecting device 12, and then the program will control the collection device 12 to run, and the collection device 12 will move to the lower left direction. The collection device 12 will make the seeds at the seeding device 11 fall and collect them, and the seeds passing through the collection device 12 will fall into the vacant area of the diverter device 13. At this time, the set amount of seeds will be temporarily stored independently by the diverter device 13.Then the program will control the storage device 9 to run upward again, and run multiple cycles again as described above, until the vacant areas in the diverter 13 are all independently temporarily stored with a set amount of seeds, and then the program will control the storage device 9 to suspend operation again until the diverter 13 has an empty area again; while the seeds are inoculated as described above, the agricultural seeder can be controlled to start, and the seeding cycle of the diverter 13 can be adjusted according to the required sowing density and travel speed of the seeder in the farmland, so that the diverter 13 can seed the set amount of seeds independently temporarily stored in it according to a certain spacing, and sow them on the farmland through the external seeding tube. ;
[0038] Embodiment 2, as Figure 6 As shown, the storage device 9 includes an electric slide rail 91 and a storage box 92. The electric slide rail 91 is fixedly connected to the right inner wall of the transport cabin 1. The electric slide rail 91 is controlled by a servo system. The electric slide rail 91 is vertically arranged. The moving part of the electric slide rail 91 is fixedly connected to the storage box 92. The storage box 92 is placed in the transport cabin 1. The inner bottom of the storage box 92 is a ramp structure facing downward to the left. The storage box 92 is a structure with a discharge port on the left side. The discharge port structure of the storage box 92 is the same size as the discharge port structure of the transport cabin 1.
[0039] The seeds passing through the external feed pipe 3 will fall into the storage box 92; when the control program executes inoculation, the program will control the electric slide rail 91 to drive the storage box 92 to move upward through its moving parts, and the storage box 92 will drive the seeds therein to move upward. At this time, the blocking device 10 blocks the discharge port structure of the storage box 92, and the blocking device 10 will also move upward until the blocking device 10 moves upward to block the reflux port structure of the transport cabin 1, and the storage box 92 will break away from the space within the blocking device 10. At this time, the inner wall of the transport cabin 1 will block the discharge port structure of the storage box 92 until the discharge port structure of the storage box 92 corresponds to the discharge port structure of the transport cabin 1, the discharge port structure of the storage box 92 will be opened, and the seeds in the storage box 92 will slide through the discharge port structure to the guide plate 7, and pass through the The inoculation is carried out through the inoculation device 11; then the electric slide rail 91 will drive the storage box 92 to move downward for reset through its moving parts, until the storage box 92 moves downward and enters the blocking device 10, the storage box 92 will drive the blocking device 10 to move downward, so that the blocking device 10 opens the reflux port structure of the transport cabin 1, so that the excess seeds at the inoculation device 11 are refluxed through the reflux port of the transport cabin 1 and the upper side of the storage box 92, so that the seeds are refluxed into the storage box 92, thus completing a seed operation cycle of inoculation; and the method of using the storage box 92 to store seeds for transportation can prevent the seeds from being collided, squeezed and sheared by the mechanical structure during transportation, and no force will be applied to the surface of the seeds, thereby protecting the yield of the seeds during transportation.
[0040] like Figure 6As shown, the blocking device 10 includes a first movable pair 101 and a baffle 102. The first movable pair 101 is fixedly connected to the fixed tube 8. The first movable pair 101 is a structure with an elastic member. The elastic member structure of the first movable pair 101 is a straight spring. The first movable pair 101 is vertically arranged. The upper end of the movable member of the first movable pair 101 is fixedly connected with a baffle 102. The baffle 102 blocks the reflux port structure of the transport cabin 1. The baffle 102 is a smooth structure with double-sided polishing, which has the effect of reducing the friction coefficient. The inner periphery of the baffle 102 is in close contact with the outer periphery of the storage box 92.
[0041] When the storage box 92 moves downward to reset and contact with the baffle 102, the storage box 92 will drive the baffle 102 to move downward. At this time, the elastic member structure of the first movable pair 101 will enter a stressed state until the baffle 102 moves downward and no longer blocks the reflux port structure of the transport cabin 1; when the storage box 92 moves upward, the elastic member structure of the first movable pair 101 will recover from the stressed state, thereby driving the baffle 102 to move upward to block the reflux port structure of the transport cabin 1, and the baffle 102 will block the excess seeds on the inoculation device 11.
[0042] like Figure 9-11 As shown, the inoculation device 11 includes a second movable pair 111, a fixed plate 112 and an inoculation mold 113. The second movable pair 111 is fixedly connected to the fixed frame 5. The second movable pair 111 is a structure with an elastic member. The elastic member structure of the second movable pair 111 is a straight spring. The moving direction of the second movable pair 111 is perpendicular to the mounting frame 4. The movable member of the second movable pair 111 is fixedly connected to the fixed plate 112. The inoculation mold 113 is sleeved between the mounting frame 4 and the fixed plate 112. The fixed plate 112 and the second movable pair 111 are used to support the inoculation mold 113 so that the inoculation mold 113 is replaceable. The inoculation mold 113 is a structure with inoculation holes arranged in an array. The collecting device 12 contacts the lower side of the inoculation mold 113 to block its inoculation holes. The number of inoculation molds 113 is not unique, and the number of inoculation molds 113 is not unique. The main body of the inoculation mold 113 is equal in size, and the thickness of the inoculation mold 113 is different, so that the inoculation mold 113 can be suitable for multiple types of seeds with different thicknesses. The aperture and number of holes of the inoculation mold 113 are not unique. The center position of the inoculation holes of the inoculation mold 113 is consistent, that is, even if the apertures and numbers of holes of the two inoculation molds 113 are not equal, the distance between the center of the inoculation hole structure on the relative edges of the inoculation mold 113 is consistent. In addition to the main structure of the inoculation mold 113 being equal in size, the other parameters of the inoculation mold 113 are not unique, so that the automatic seeding equipment of the agricultural seeder can be suitable for more types of seeds, and different sowing methods can be achieved for different types of seeds. The lower side of the inoculation mold 113 is a structure with a guide groove, and the guide groove structure of the inoculation mold 113 is used to cooperate with the seed collection work of the collection device 12.
[0043] The inoculation mold 113 can be replaced with different seed diameters and sowing quantities suitable for this sowing. The inoculation mold 113 is inserted into the space between the fixed plate 112 and the mounting frame 4. The second movable pair 111 and its elastic member structure will press the inoculation mold 113. The seeds passing through the guide plate 7 will fall on the inoculation mold 113. When a large number of seeds slide off the inclined inoculation mold 113, some of the seeds will fall on a fixed position in the inoculation hole of the inoculation mold 113. The collecting device 12 will block the seeds at this position, and the remaining seeds will slide down the inoculation mold 113 diagonally to the lower right. position and the reflux port structure of the transport cabin 1; when the reflux port structure of the transport cabin 1 is opened, the seeds on the inoculation mold 113 continue to slide back into the storage box 92; when the program-controlled collecting device 12 is running, the collecting device 12 will break away from the contact with the inoculation mold 113 in the guide groove, so that the seeds in the inoculation hole structure of the inoculation mold 113 fall into the collecting device 12 for collection, until the program-controlled collecting device 12 is reset and contacts the lower side of the inoculation mold 113 again to block its inoculation hole structure, so that the inoculation program can carry out the next wave of seed inoculation work.
[0044] like Fig.12 As shown, the collecting device 12 includes a first electric push rod 121, a collecting box 122 and a guide pipe 123. The first electric push rod 121 is fixedly connected to the extension frame 6. The first electric push rod 121 is controlled by a servo system. The moving part of the first electric push rod 121 runs in a direction perpendicular to the mounting frame 4. The upper end of the moving part of the first electric push rod 121 is fixedly connected to the collecting box 122. The collecting box 122 is an open structure on the upper side. The open structure on the upper side of the collecting box 122 is embedded in the guide groove of the inoculation mold 113 through its four sides, so that the bottom surface of the collecting box 122 is in contact with the lower side of the inoculation mold 113. The guide pipe 123 is fixedly connected to the lower right side of the collecting box 122. The guide pipe 123 is a hose structure, and the lower side of the guide pipe 123 is connected to the diversion device 13.
[0045] When the inoculation mold 113 completes receiving the seeds, the program will control the first electric push rod 121 to drive the collecting box 122 to move obliquely to the lower left direction through its moving part, so that the inner bottom surface of the collecting box 122 is separated from the contact with the lower bottom surface of the inoculation mold 113, so that the seeds in the inoculation hole structure of the inoculation mold 113 fall into the collecting box 122, and slide through the obliquely arranged collecting box 122 to the guide pipe 123, and flow into the diversion device 13 through the guide pipe 123.

There are multiple independent temporary storage areas of the seed sorting mechanism 14, and all of them have the function of self-checking whether they contain seeds, and all of them have the function of opening and closing. The protective ring 131 is used to protect the seed sorting structure from external impurities entering. A trigger mechanism 15 is provided on the right side of the connecting frame 133. The trigger mechanism 15 and the docking tube 134 are on the same vertical line. The trigger mechanism 15 is controlled by a servo system. The trigger mechanism 15 is used to trigger the opening of a temporary storage area of the seed sorting mechanism 14 below it, so that the temporary storage area of the seed sorting mechanism 14 releases its seeds into the docking tube 134.
[0047] like Figure 13-Figure 16 As shown, the seed separation mechanism 14 includes an annular frame 141, a shunt pipe 142, a third moving pair 143, a support plate 144 and a weight sensor 145. The annular frame 141 is fixedly connected to the outer periphery of the moving part of the electric annular slide rail 132. A plurality of shunt pipes 142 are fixedly connected to the outer periphery of the annular frame 141 in an array-like manner. The shunt pipes 142 are pipeline structures. The shunt pipes 142 are used to temporarily store seeds. The outer peripheries of the shunt pipes 142 are fixedly connected to the third moving pair 143. The third moving pairs 143 are structures with elastic parts. The elastic part structures of the third moving pairs 143 are all straight springs. The lower ends of the moving parts of the third moving pairs 143 are fixedly connected to support plates 144. The support plates 144 respectively block the lower openings of the shunt pipes 142 corresponding to the positions. The upper sides of the support plates 144 are fixedly connected to weight sensors 145. The weight sensors 145 are used to self-check whether there are seeds inside the shunt pipes 142 at this position.
[0048] like Fig.15As shown, the trigger mechanism 15 includes a second electric push rod 151 and a push block 152. The second electric push rod 151 is fixedly connected to the right side of the connecting frame 133. The second electric push rod 151 is controlled by a servo system. The operation cycle time of the second electric push rod 151 is set according to the sowing density required for the farmland and the travel speed of the seeder. The second electric push rod 151 is vertically arranged. The lower end of the moving part of the second electric push rod 151 is fixedly connected with a push block 152. The push block 152 can respectively cooperate with the upper end of the moving part of the third moving pair 143 thereunder. The second electric push rod 151 and the push block 152 are used to push the moving part of the third moving pair 143 thereunder to move downward, so that the support plate 144 at this position is separated from the contact with the shunt pipe 142 at this position, so that the seeds in the shunt pipe 142 at this position fall into the docking pipe 134 thereunder.
[0049] The seeding method of the diverter device 13 is as follows: the operation cycle of the second electric push rod 151 is set according to the required sowing density of the farmland and the travel speed of the seeder; within one operation cycle of the second electric push rod 151, each weight sensor 145 will detect whether there are seeds in the diverter tube 142 corresponding to its position, and the electric annular slide rail 132 can drive the annular frame 141 and the diverter tubes 142 distributed in the array to rotate, so that the diverter tubes 142 containing seeds rotate to the position below the second electric push rod 151. If the diverter tube 142 at the position below the second electric push rod 151 already contains seeds, the electric annular slide rail 132 will not work. At this time, the second electric push rod 151 will drive the push block 152 to move downward through its moving part, so that the push block 152 pushes the moving part of the third moving pair 143 below it to move downward, so that the support plate 144 at this position moves downward and breaks away from the contact with the bottom of the shunt pipe 142 at this position, so that the seeds in the shunt pipe 142 at this position fall into the docking pipe 134, and finally flow out of the seed outlet pipe of the seeder to the farmland, completing the sowing, and then the second electric push rod 151 will drive the push block 152 to move upward for reset through its moving part, and the support plate 144 at this position will be reset by the elastic part of the third moving pair 143 at this position, so that the shunt pipe 142 at this position is in an empty state.
[0050] The seed temporary storage method of the diverter device 13 is as follows: when the second electric push rod 151 is not in the operation cycle, each weight sensor 145 will detect whether there are seeds in the diverter tube 142 corresponding to its position, and the electric annular slide rail 132 can drive the annular frame 141 and the diverter tubes 142 distributed in the array to rotate, so that the diverter tube 142 without seeds is rotated to the position below the guide tube 123, that is, an empty diverter tube 142 is rotated to the position below the guide tube 123. If the diverter tube 142 below the guide tube 123 is already in an empty state, the electric annular slide rail 132 will not work. At this time, the program controls the collecting device 12 to work, so that the seeds in the inoculation device 11 pass through the collecting device 12 and the guide tube 123 and fall into the empty diverter tube 142 below it.
[0051] The seed discharge and temporary storage method of the above-mentioned diverter device 13, through the array-distributed multiple diverter tubes 142 to independently temporarily store the quantitative seeds, can adapt to the requirements of different sowing speeds and different sowing densities when sowing in farmland, that is, multiple diverter tubes 142 store seeds, and the operating cycle speed of the second electric push rod 151 is set, which can maintain the supply of quantitative seeds, adapt to faster sowing speeds or higher sowing densities, and improve the degree of automation and work efficiency when sowing in farmland.
[0052] Embodiment 3, as Figure 3 and Fig.12 As shown, a detection mechanism 16 is also included. The detection mechanism 16 includes an infrared detection module 161 and a reflective mirror 162. The infrared detection module 161 is fixedly connected to the lower side of the guide plate 7. The main structure of the infrared detection module 161 is parallel to the inoculation mold 113. The infrared detection module 161 is a detection head with an array distribution. The detection head structure of each infrared detection module 161 is independently electrically controlled. The reflective mirror 162 is distributed in an array on the bottom surface of the collection box 122. The detection direction of each detection head of the infrared detection module 161 is vertically arranged with the reflective mirror 162 corresponding to the position. The distribution of the detection heads of the detection module 161 is consistent with the arrangement and setting of the array of inoculation holes of the inoculation mold 113, and the array distribution of the reflecting mirror 162 is consistent with the array arrangement of the detection heads of the infrared detection module 161, so that each detection head of the infrared detection module 161 can pass through the inoculation holes of the inoculation mold 113 and illuminate the reflecting mirror 162 at the corresponding position. After parallel reflection by the reflecting mirror 162, the detection head structure of the infrared detection module 161 can receive the infrared signal reflected at this position to confirm that the inoculation hole structure at this position of the inoculation mold 113 is in a vacant state.
[0053] When the seeds are inoculated from the guide plate 7 through the inoculation mold 113 and the seeds flow back into the collecting device 12, the program will control the infrared detection module 161 to start, and each detection head structure of the infrared detection module 161 will emit an infrared signal. If no infrared signal is returned by the reflective mirror 162 and received by the infrared detection module 161, it means that all the inoculation holes of the inoculation mold 113 have received seeds, indicating that the inoculation quantity has reached the set amount. If one or more infrared signals are returned by the reflective mirror 162 and received by the infrared detection module 161, it means that the inoculation quantity has not reached the set amount. At this time, the program The storage device 9 is controlled to operate again, so that the inoculation device 11 receives seeds again until the set amount is reached. This method can ensure that the inoculation mold 113 can receive the set amount of seeds each time it is inoculated, ensuring that the number of seeds collected by the collecting device 12 is the set amount, so that the sowing amount meets the standard each time it is sown; in addition, the electrical control on and off of the detection head structure corresponding to the position of the infrared detection module 161 can be adjusted according to the inoculation molds 113 with different numbers of holes placed on the mounting frame 4, so that the detection head of the infrared detection module 161 can adapt to the inoculation molds 113 with different numbers of holes for detection.
[0054] like Figure 1 and Figure 3 As shown, it also includes a covering cabin 17, which is fixedly connected to the upper side of the mounting frame 4. The covering cabin 17 covers the upper space of the mounting frame 4, and the covering cabin 17 covers the upper space of the guide plate 7 and the discharge port structure of the transport cabin 1, so that the space above the mounting frame 4 and the guide plate 7 will not be entered by external impurities, and at the same time, it can prevent the vibration of the seeder during its movement, causing the seeds to slip and be scattered to the outside.
[0055] The cover cabin 17 can prevent the space above the mounting frame 4 and the guide plate 7 from being entered by foreign matter, and at the same time prevent the seeds from being scattered to the outside during the process of sliding due to the vibration of the seeder during travel.
[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
