[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1 - Fig.11 A sowing device for greenhouse vegetable planting comprises a seeder body 1, a power unit 9 connected to the seeder body 1, a furrow unit 2 connected below the seeder body 1 and a depth adjustment unit 3 connected to both sides of the furrow unit 2. The seeder body 1 is connected to the sowing unit, the sowing unit comprises a plurality of storage chambers 4 and a seed dropping assembly, the seed dropping assembly comprises a plurality of inverted buckets 6 connected to the bottom of the storage chamber 4, a rectangular frame 24 is fixedly connected to the bottom of the inverted bucket 6, a seed receiving ball 25 is rotatably connected in the rectangular frame 24, a seed receiving ball 25 is provided with a seed groove 21, a clamping shaft 26 is fixedly connected to both sides of the seed receiving ball 25, the outer end of the clamping shaft 26 passing through the rectangular frame 24 is fixedly connected to a rotating shaft 7, one end of the rotating shaft 7 is connected to a reduction module 8 transmission-connected to the power unit 9, and an adjustable seed bin structure is connected to the outside of the storage chamber 4.

[0019] When the seeding device for greenhouse vegetable planting of the present invention is in use, seeds are poured into a plurality of storage chambers 4. The seeds enter the inverted bucket 6 under the action of gravity, and then enter the rectangular frame 24 below the inverted bucket 6. Since a seed groove 21 is provided on the seed receiving ball 25 in the rectangular frame 24, and the rotating shaft 7 is connected to the power unit 9 through the reduction module 8, that is, the power unit 9 drives the reduction module 8 through the transmission chain, and the reduction module 8 drives the rotating shaft 7 to rotate. Since the clamping shaft 26 is coaxial with the rotating shaft 7, when the rotating shaft 7 rotates, each seed receiving ball 25 in the group of seed dropping components is driven to rotate about the axis of the clamping shaft 26. When the seed receiving ball 25 rotates until the seed groove 21 faces upward, the seeds in the rectangular frame 24 are brought into the seed groove 21. As the rotating shaft 7 rotates, the seed groove 21 of the seed receiving ball 25 is driven downward, and the seeds are dropped again. As the rotating shaft 7 rotates, the seeds matching the seed receiving ball 25 will just fall into the seed groove 21, and as the seed groove 21 of the seed receiving ball 25 repeatedly moves upward and downward, the seeds fall; Through the mutual cooperation of the seed receiving ball 25, the clamping shaft 26 and the seed groove 21, under the rotation of the rotating shaft 7, it is ensured that the seeds are repeatedly inoculated and discharged from the seed groove 21 of the seed receiving ball 25, so that the seeds are discharged one by one. Compared with the original spoon receiving, this arrangement avoids the problem of empty spoons caused by the vibration of the machine running, ensures the sowing density, and improves the sowing efficiency.

[0020] As a preferred technical solution of the present invention, the adjustable structure of the seed bin includes multiple side rods 12 and two end rods 13, the outer walls of each storage cavity 4 are fixedly connected with side rods 12 on both sides, the ends of multiple side rods 12 are fixedly connected with end rods 13, and the bottom surface of each side rod 12 is provided with a slide groove 29. The seed dropping components are arranged in multiple groups, and the outer walls of each inverted bucket 6 in each group of seed dropping components are fixedly connected with slide bars 28 slidably connected to the slide groove 29 on both sides. The diameter of the seed groove 21 of the seed receiving ball 25 in the multiple groups of seed dropping components increases successively from front to back, and the ends of the two end rods 13 are connected to the frame of the seeder body 1 through the top plate 16.

[0021] Specifically, when sowing, since different vegetable seeds have different diameters, in order to make the sowing machine body 1 adapt to the sowing of seeds of different vegetable diameters, the adjustable structure of the seed bin can be adjusted; Since there are multiple seed dropping assemblies, and the diameter of the seed groove 21 in each seed receiving ball 25 in each group of seed dropping assemblies is equal, the diameter of the seed groove 21 in the multiple groups of seed receiving balls 25 increases from front to back, so each group of seed dropping assemblies can be pushed and replaced according to the diameter of the seeds; When replacing, the seed dropping assembly is separated from the deceleration module 8, and then the seed dropping assembly to be replaced is pushed, so that the rotating shaft 7 in the seed dropping assembly to be replaced drives the bucket 6, the rectangular frame 24, and the clamping shaft 26 to move, and drives the slide bar 28 on the outer wall of the rectangular frame 24 to move in the slide groove 29 in the side rod 12, so that the seed dropping assembly to be replaced is connected with the bottom of the storage chamber 4, and the rotating shaft 7 of the seed dropping assembly is connected with the deceleration module 8, so that when the power unit 9 is driven, the deceleration module 8 will be driven to move, and the rotating shaft 7 will be driven to rotate; Since the diameter of the seed groove 21 in the seed receiving ball 25 in each set of seed dropping components increases successively, the seed receiving ball 25 after replacement can cope with the sowing of vegetable seeds of different diameters; By making the inverted bucket 6, rectangular frame 24 and seed receiving ball 25 replaceable, it is convenient to adapt to the sowing of vegetable seeds of different diameters and improve the sowing adaptation range. By replacing the rotating shaft 7 at one time, the difficulty of replacement can be reduced. Compared with the original method of taking the seed spoon out of each spoon plate, the operation convenience is further improved and the operation complexity is reduced.

[0022] As a preferred technical solution of the present invention, the outer side of the reduction module 8 is connected to a shell 31, the outer side of the shell 31 is connected to an adjusting paddle 10 connected to the reduction module 8, the power unit 9 is connected to the reduction module 8 through a transmission chain, the output shaft of the reduction module 8 is fixedly connected to a transmission shaft 11, the transmission shaft 11 passes through one end of the shell 31 and is fixedly connected to an insertion rod 30 on the outer side, and a slot 20 corresponding to the insertion rod 30 is opened at one end of the rotating shaft 7.

[0023] Specifically, when sowing, the spacing between plants needs to be adjusted. Therefore, when the spacing between plants needs to be adjusted, the rotation speed of the seed receiving ball 25 can be adjusted according to the rotation speed of the rotating shaft 7. In the process of moving and fixing, the rotation speed of the rotating shaft 7 determines the rotation speed of the seed receiving ball 25 and determines the speed of seed discharge. Therefore, the speed reduction module 8 can be operated by adjusting the paddle 10, so that the transmission chain in the power unit 9 is adjusted on the speed reduction module 8, so as to realize the speed adjustment of the rotating shaft 7. In the above structure, the speed adjustment of the rotating shaft 7 by the adjustment paddle 10 for the deceleration module 8 should be an existing mature technology, just like the speed adjustment principle of a mountain bike, so it will not be further described in detail here.

[0024] As a preferred technical solution of the present invention, a sliding assembly is connected between the top plate 16 and the end rod 13, and the sliding assembly includes a sliding rod 22 and an extrusion spring 23. The sliding rod 22 is slidably connected inside the two end rods 13, and the two ends of the two sliding rods 22 are fixedly connected to the top plate 16. The outer walls of the two sliding rods 22 are sleeved with extrusion springs 23, and the two ends of the two extrusion springs 23 are respectively against the top plate 16 and the outer walls of the end rods 13.

[0025] Specifically, when each set of seed dropping components is adjusted, the rotating shaft 7 can be smoothly disengaged from the transmission shaft 11 on the reduction module 8. During operation, the end rod 13 can be pulled first to drive the end rod 13 to slide outside the slide rod 22. Since the storage chamber 4 is fixedly connected to the side rod 12, when the end rod 13 slides outside the slide rod 22, the end rod 13 drives the side rod 12, the storage chamber 4, and the seed dropping components to move at the same time. When the seed dropping components move, the slot 20 at the end of the rotating shaft 7 in the seed dropping component to be replaced is disengaged from the insertion rod 30 at the end of the transmission shaft 11 of the reduction module 8. After the disengagement, the seed dropping assembly to be replaced is pushed to move from the frame of the seeding machine body 1, so that the bucket 6 in the seed dropping assembly is located below the bottom of the storage chamber 4, and the end rod 13 is restored at this time, and the end rod 13 is reset under the action of the extrusion spring 23; When the end rod 13 is reset, the side rod 12, the storage chamber 4, the slide bar 28, the bucket 6, the rectangular frame 24, the seed receiving ball 25 and the shaft 7 are all reset and slide toward one end of the transmission shaft 11 on the speed reduction module 8. At this time, the slot 20 on the shaft 7 can be plugged into the plug rod 30 to complete the limit. Since a squeeze spring 23 is disposed on the outer side of the slide bar 22, when the seed dropping assembly drops seeds normally, the force of the squeeze spring 23 can ensure that the rotating shaft 7 and the transmission shaft 11 are always kept together.

[0026] As a preferred technical solution of the present invention, a seed guide assembly is installed under each group of seed receiving balls 25, and the seed guide assembly includes multiple collecting covers 14. The bottom of each collecting cover 14 is fixedly connected to a feeding hose 15, and the feeding hose 15 is connected to the furrow unit 2. Connectors are connected to the outer sides of the multiple collecting covers 14.

[0027] Specifically, in order to facilitate the seeds to be guided to the ground after falling, the collecting cover 14 is used. When the seed dropping assembly is replaced and adjusted, the collecting cover 14 is always located at the bottom to ensure the seeds are guided downward; The feeding hose 15 is a hose arrangement, which can meet the spacing adjustment of the furrow unit 2 and facilitate the adjustment of the row spacing; It is worth noting that the depth adjustment unit 3 and the furrow unit 2 are both existing mature technologies and have not been improved. The structure of the present application can also meet the adjustment requirements of the depth adjustment unit 3 and the furrow unit 2.

[0028] As a preferred technical solution of the present invention, the connecting part includes multiple lap frames 18, each collecting cover 14 is fixedly connected to the top with a peripheral edge 17, the peripheral edge 17 is overlapped with the lap frame 18, and the two ends of the multiple lap frames 18 are fixedly connected to connecting rods 19 fixedly connected to the seeder frame.

[0029] Specifically, in order to facilitate the installation of the collecting hood 14 , the outer peripheral edge 17 of the collecting hood 14 can be overlapped on the overlapping frame 18 , which makes it easier to install the collecting hood 14 .

[0030] As a preferred technical solution of the present invention, an installation groove 33 is opened on the frame of the seeder body 1, and a limiting component is connected to the frame of the seeder body 1, and the limiting component includes a U-shaped limit block 32, and the U-shaped limit block 32 is located on the outside of the rotating shaft 7 connected to the deceleration module 8, and the U-shaped limit block 32 is slidably connected in the installation groove 33, and the bottom of the U-shaped limit block 32 is fixedly connected with a lifting spring 27, and the other end of the lifting spring 27 is connected to the bottom surface of the installation groove 33.

[0031] Specifically, in order to make the rotating shaft 7 more stable during rotation, when the rotating shaft 7 is pushed, it will first disengage from the U-shaped limit block 32, and the next rotating shaft 7 will enter the U-shaped limit block 32. Under the action of the lifting spring 27, the U-shaped limit block 32 ensures that the height of the U-shaped limit block 32 remains unchanged, and the rotating rotating shaft 7 is always limited.

[0032] As a preferred technical solution of the present invention, a bell mouth 5 is fixedly connected to the top of the storage cavity 4 .

[0033] Specifically, the arrangement of the bell mouth 5 facilitates the pouring of seeds.

[0034] In the above structure, the power unit 9 is a prior art, and the transmission through the transmission chain and the reduction module 8 and the rotation of the shaft 7 are all existing mature technologies, so they will not be described in detail here.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
