Description

Technical Field

[0001] The invention relates to the technical field of agricultural sowing machinery, and in particular to a seed conveying device for a sowing machine. Background Art

[0002] A seeder is a planting machine that sows crop seeds. The emergence of seeders has greatly increased agricultural work efficiency, reduced agricultural labor, and reduced sowing time. The main equipment of a seeder is a device that enables seeds to be automatically fed and transported.

[0003] The existing seed drill seed conveying device is basically a disc-type rotating feeding method. The seeding disc is equidistantly provided with a plurality of slots for clamping the seeds. During installation, a part of the seeding disc is placed in the seed bin, and the other part is connected to the feed pipe. During operation, the seeding disc rotates, and the slots bring the seeds out of the seed bin in batches for sowing. However, since the seeds are usually small in size, and the seed drill will produce a large shake when it is running and moving forward on the land, some small seeds are easy to fall from the slots. At the same time, the shaking seeds in the seed bin cannot fall into the slots that are constantly rotating forward in time. Therefore, it is very easy to miss or under-sow. At the same time, the current spoon-type sowing and stick-wheel pit-type sowing methods all have the problem of stuck seeds and damaged seed skins, resulting in a low crop emergence rate, thereby increasing farmers' farming costs. Therefore, in order to solve the problems existing in the above-mentioned prior art, a seed conveying device for a seed drill is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a seed conveying device for a seeder.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A seed conveying device for a seed drill comprises a mounting frame, a group of bearing seats are fixed on the outer wall of the top of the mounting frame, a round tube is rotatably connected to the inner wall of the bearing seat, a plurality of partition plates are fixed to the inner wall of the round tube, a fixed tube is fixed to one end of the partition plate, the fixed tube and the partition plate divide the inner wall of the round tube into a plurality of cavities, a plurality of adsorption holes are opened on the outer wall of the round tube, and each group of adsorption holes corresponds to a cavity respectively;

[0007] The outer wall of the circular tube is slidably connected with a sealing ring, and the inner wall of the sealing ring is provided with an annular air guide groove and an exhaust hole. Among the multiple groups of adsorption holes on the outer wall of the circular tube, more than one adsorption hole slides on one side of the annular air guide groove and the exhaust hole.

[0008] Preferably: a fixing block is fixed to the outer wall of the sealing box, an end cover is fixed to the outer wall of the fixing block, and one end of the round tube is rotatably connected to the inner wall of the end cover;

[0009] The inner wall of one side of the end cover is respectively provided with a vent hole, a rotation connection hole and an air extraction annular groove, the inner wall of the air extraction annular groove is provided with an air extraction hole, and the vent hole, the rotation connection hole and the air extraction hole are respectively passed through the outer wall of one side of the end cover;

[0010] The air extraction hole is connected with the inside of the sealing box through an air guide pipe, and a sealing head is plugged into the inner wall of the rotating connection hole.

[0011] Preferably, a connecting block is integrally formed on the outer wall of the sealing ring, an air guide channel is opened on the inner wall of the connecting block, and the air guide channel is connected to the annular air guide groove.

[0012] Further: a sealing box is fixed to the bottom outer wall of the connection block by screws, an outer wall on one side of the sealing box is fixed to the mounting frame, and an air guide channel runs through the top outer wall of the sealing box and is connected to the inside of the sealing box.

[0013] Further preferably, a mounting box is fixed to an outer wall of one side of the mounting frame, a vacuum pump is fixed to an inner wall of the mounting box, an air filter is arranged on the inner wall of the sealing box, and the air filter is connected to an input end of the vacuum pump through a pipeline.

[0014] As a preferred embodiment of the present invention: a bracket is fixed to the outer wall of the mounting frame, a seed bin is fixed to the outer wall of the bracket, and a round tube penetrates the outer walls on both sides of the seed bin.

[0015] As a further preferred embodiment of the present invention: a plurality of feed pipes are fixed to the bottom of the seed bin, and the feed pipes penetrate through the outer wall of the bottom of the seed bin.

[0016] As a further solution of the present invention: a sealing disc and a transmission gear disc are fixed to both ends of the fixed pipe by screws respectively.

[0017] On the basis of the above-mentioned solution: a reserved groove is provided on the outer wall at the top of the feed tube.

[0018] Based on the above scheme, it is preferred that: a reinforcing plate is fixed to the outer wall of the bearing seat, and the outer wall of one side of the seed bin is fixed to the outer wall of the reinforcing plate.

[0019] The beneficial effects of the present invention are:

[0020] 1. When the vacuum pump is in operation, air will be extracted through the annular air guide groove and the adsorption holes that rotate to one side of the annular air guide groove. Since there are sealing discs and transmission gear discs at both ends of the circular tube for sealing, when air is extracted through the adsorption holes, negative pressure will be formed on the inner wall of the corresponding cavity that rotates to the side of the annular air guide groove, so that a group of adsorption holes corresponding to the outer wall of the cavity can adsorb the seeds blocked on one side of the circular tube, so as to prevent the seeds from falling from the outer wall of the circular tube due to the shaking of the seeder during transportation. At the same time, the negative pressure of the adsorption holes can stably adsorb the seeds inside the seed bin on the outer wall of the circular tube for transportation, so as to avoid missed sowing, insufficient sowing, stuck seeds and damage to the seed skin during sowing, thereby improving the survival rate of seeds and reducing farmers' farming costs.

[0021] 2. The vacuum pump inhales air, causing negative pressure to form in the cavity on the inner wall of the circular tube, and the seeds are sucked up through the adsorption holes. When the seeds are adsorbed, fine particles such as dust will be sucked into the sealed box. At this time, the dust will remain in the sealed box under the obstruction of the air filter, thereby effectively protecting the vacuum pump.

[0022] 3. The diameter of the adsorption hole and the power of the vacuum pump can be adjusted according to the size of the specific seeds. At the same time, the number of partition plates on the inner wall of the circular tube can be adjusted according to different sowing densities, thereby forming different numbers of cavities and improving the applicability of the seed conveying device.

[0038] Embodiment 1:

[0039] A seed conveying device for a seed drill, such as Figure 1-8 As shown, it includes a mounting frame 1, a group of bearing seats 9 are fixed to the outer wall of the top of the mounting frame 1, a round tube 2 is rotatably connected to the inner wall of the bearing seat 9, a plurality of partition plates 18 are fixed to the inner wall of the round tube 2, a fixed tube 19 is fixed to one end of the partition plate 18, the fixed tube 19 and the partition plate 18 divide the inner wall of the round tube 2 into a plurality of cavities, and a plurality of groups of adsorption holes 4 are opened on the outer wall of the round tube 2, and each group of adsorption holes 4 corresponds to a cavity respectively;

[0040] The fixed tube 19 can be hollow or solid;

[0041] The outer wall of the circular tube 2 is slidably connected with a sealing ring 13, and the inner wall of the sealing ring 13 is provided with an annular air guide groove 22 and an exhaust hole 21. Among the multiple groups of adsorption holes 4 on the outer wall of the circular tube 2, more than one adsorption hole 4 slides on one side of the annular air guide groove 22 and the exhaust hole 21.

[0042] The outer wall of the sealing ring 13 is integrally formed with a connecting block 14, and the inner wall of the connecting block 14 is provided with an air guide channel 23, which is connected to the annular air guide groove 22;

[0043] The bottom outer wall of the connection block 14 is fixed with a sealing box 8 by screws, and one side outer wall of the sealing box 8 is fixed to the mounting frame 1. The air guide channel 23 runs through the top outer wall of the sealing box 8 and is connected to the inside of the sealing box 8.

[0044] A mounting box 6 is fixed to the outer wall of one side of the mounting frame 1, a vacuum pump 17 is fixed to the inner wall of the mounting box 6, an air filter element 16 is arranged on the inner wall of the sealing box 8, and the air filter element 16 is connected to the input end of the vacuum pump 17 through a pipeline.

[0045] The outer wall of the mounting frame 1 is fixed with a bracket 10, the outer wall of the bracket 10 is fixed with a seed bin 3, and the round tube 2 penetrates the outer walls of both sides of the seed bin 3;

[0046] A plurality of feed pipes 5 are fixed at the bottom of the seed bin 3, and the feed pipes 5 penetrate the outer wall of the bottom of the seed bin 3;

[0047] The two ends of the fixed tube 19 are fixed with a sealing disc 7 and a transmission gear disc 11 by screws 15 respectively; the outer wall of the top of the discharge tube 5 is provided with a reserved groove 20.

[0048] The transmission gear disc 11 can be a gear disc or other disc-shaped structure that can drive the circular tube 2 to rotate and shield and seal one end of the circular tube 2 .

[0049] The staff first pours the seeds into the seed bin 3. At this time, the round tube 2 located on the inner wall of the seed bin 3 blocks the seeds poured into the seed bin 3 to prevent the seeds from being directly discharged outward through the discharge pipe 5 on one side of the seed bin 3.

[0050] Then the staff starts the engine of the seeder. When the engine is running, the transmission gear plate 11 can be driven to rotate through the gearbox and the transmission chain, thereby driving the circular tube 2 to roll as a whole inside the seed bin 3. At the same time, the staff turns on the vacuum pump 17 located inside the mounting box 6. When the vacuum pump 17 is running, air is extracted through the annular air guide groove 22 and the adsorption holes 4 that rotate to one side of the annular air guide groove 22. Since the sealing discs 7 and the transmission gear plates 11 are provided at both ends of the circular tube 2 for sealing and blocking, when air is extracted through the adsorption holes 4, negative pressure is formed on the inner wall of the cavity that rotates to the side of the annular air guide groove 22, so that a group of adsorption holes 4 corresponding to the outer wall of the cavity adsorb the seeds blocked on one side of the circular tube 2, so as to prevent the seeds from falling from the outer wall of the circular tube 2 due to the shaking of the seeder during transportation. At the same time, the seeds inside the seed bin 3 can be stably adsorbed on the outer wall of the circular tube 2 for transportation through the negative pressure of the adsorption holes 4, so as to avoid the phenomenon of missed or under-sowing during sowing.

[0051] Since the adsorption holes 4 have a small diameter, they can adsorb one seed at a time, and a row of seeds adsorbed on one side of the adsorption holes 4 continue to rotate forward with the circular tube 2. When the adsorption holes 4 located on the inner wall of the sealing ring 13 rotate to the side of the exhaust hole 21, the external gas will quickly enter the corresponding cavity through the adsorption holes 4, so that the air pressure inside the cavity is consistent with the external air pressure, thereby releasing the negative pressure adsorption of the adsorption holes 4 on the seeds on one side. At this time, a row of seeds located on the outer wall of the group of adsorption holes 4 just follow the circular tube 2 to move to the side of the reserved groove 20 on the outer wall of the feeding tube 5, and then they can be dropped into the feeding tube 5 by their own gravity and the inertia of the circular tube 2 rotating forward, thereby regularly and continuously transporting seeds outward through the feeding tube 5.

[0052] The diameter of the adsorption hole 4 and the power of the vacuum pump 17 can be adjusted according to the size of the specific seeds. At the same time, the number of the inner wall partitions 18 of the circular tube 2 can be adjusted according to different sowing densities, thereby forming different numbers of cavities and improving the applicability of the seed conveying device.

[0053] When the vacuum pump 17 is running, it will first absorb the gas inside the sealed box 8, thereby forming a negative pressure inside the sealed box 8. After the negative pressure is formed inside the sealed box 8, air will be sucked in through the air guide channel 23 connected to the inside of the connecting block 14, so that the adsorption holes 4 that slide over on one side will be sucked in through the annular air guide groove 22 inside the sealing ring 13 that is connected to the air guide channel 23, thereby generating a negative pressure in the cavity corresponding to the inner wall of the circular tube 2, so that the row of adsorption holes 4 corresponding to one side of the cavity can perform negative pressure adsorption on the seeds.

[0054] The vacuum pump 17 draws air, causing negative pressure to form in the cavity on the inner wall of the circular tube 2, and the seeds are sucked up through the adsorption holes 4. When the seeds are adsorbed, fine particles such as dust are sucked into the sealing box 8. At this time, the dust will remain in the sealing box 8 under the obstruction of the air filter 16, thereby effectively protecting the vacuum pump 17.

[0055] A reinforcing plate 12 is fixed to the outer wall of the bearing seat 9, and the outer wall of one side of the seed bin 3 is fixed to the outer wall of the reinforcing plate 12; the reinforcing plate 12 can cooperate with the bracket 10 to support the seed bin 3 as a whole, thereby improving the stability of the seed bin 3 as a whole when the seeder is running.

[0056] When the present embodiment is in use, the staff first pours the seeds into the seed bin 3, and then starts the engine of the seeder. When the engine is running, the transmission gear disc 11 can be driven to rotate through the gearbox and the transmission chain, thereby driving the circular tube 2 to roll as a whole inside the seed bin 3. At the same time, the staff turns on the vacuum pump 17 located inside the mounting box 6. When the vacuum pump 17 is running, air is extracted through the annular air guide groove 22 and the adsorption holes 4 that rotate to one side of the annular air guide groove 22. Since the sealing discs 7 and the transmission gear discs 11 are provided at both ends of the circular tube 2 for sealing, negative pressure is formed on the inner wall of the cavity that rotates to the side of the annular air guide groove 22 when air is extracted through the adsorption holes 4, so that a group of adsorption holes 4 corresponding to the outer wall of the cavity adsorb the seeds blocked on one side of the circular tube 2.

[0057] Since the adsorption hole 4 has a small diameter, it can adsorb one seed at a time. A row of seeds adsorbed on one side of the adsorption hole 4 continues to rotate forward with the circular tube 2. When the adsorption hole 4 located on the inner wall of the sealing ring 13 rotates to the side of the exhaust hole 21, the external gas will quickly enter the corresponding cavity through the adsorption hole 4, making the internal air pressure of the cavity consistent with the external air pressure, thereby releasing the negative pressure adsorption of the seeds on one side by the adsorption hole 4. At this time, a row of seeds located on the outer wall of the group of adsorption holes 4 just follows the circular tube 2 to move to the side of the reserved groove 20 on the outer wall of the discharge pipe 5, and then they can be dropped into the discharge pipe 5 by their own gravity and the inertia of the forward rotation of the circular tube 2, thereby regularly and continuously transporting the seeds outward through the discharge pipe 5.

[0058] Embodiment 2:

[0059] A seed conveying device for a seed drill, such as Figure 9-10 As shown, a fixing block 28 is fixed to the outer wall of the sealing box 8, an end cover 24 is fixed to the outer wall of the fixing block 28, and one end of the round tube 2 is rotatably connected to the inner wall of the end cover 24;

[0060] The inner wall of one side of the end cover 24 is respectively provided with a vent hole 25, a rotation connection hole 30 and an air extraction annular groove 31, and the inner wall of the air extraction annular groove 31 is provided with an air extraction hole 29. The vent hole 25, the rotation connection hole 30 and the air extraction hole 29 are respectively passed through the outer wall of one side of the end cover 24;

[0061] The air extraction hole 29 is connected to the interior of the sealing box 8 through the air guide pipe 27 , and a sealing head 26 is inserted into the inner wall of the rotating connection hole 30 .

[0062] When one of the cavities on the inner wall of the circular tube 2 rotates to the side of the air extraction annular groove 31, the negative pressure inside the sealing box 8 absorbs the gas inside the cavity through the air guide tube 27, the air extraction hole 29 and the air extraction annular groove 31, thereby forming a negative pressure inside the cavity, so that the adsorption holes 4 corresponding to one side of the cavity can adsorb the seeds on one side of the circular tube 2;

[0063] As the circular tube 2 continues to rotate forward, the cavity corresponding to one side of the circular tube 2 and a row of seeds adsorbed on one side of the cavity will rotate to the side of the air release hole 25. At this time, the cavity is connected to the external environment through the air release hole 25, thereby relieving the negative pressure inside the cavity. At this time, the seeds that rotate to the side of the discharge pipe 5 with the circular tube 2 will fall due to their own gravity and the inertia of the circular tube 2 rotating forward, and the seeds will be discharged outward in an orderly manner through the discharge pipe 5.

[0064] When the fixed tube 19 is a hollow structure, the corresponding support shaft can be inserted into the rotating connection hole 30 and the inner wall of the fixed tube 19, so as to cooperate with the inner wall of the end cover 24 to support the rotating round tube 2, thereby improving the stability of the round tube 2 during rotation;

[0065] At the same time, the rotating connection hole 30 can be sealed by the sealing head 26 to improve the overall sealing performance of the end cover 24 .

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
