Technical Field

[0001] The present invention relates to the technical field of vegetable sowing, and particularly to a sowing device for greenhouse vegetable planting. Background Art

[0002] When planting greenhouse vegetables, a seeder is generally used, such as a spoon-type seeder. The spoon-type seeder is a commonly used precision seeding device, which realizes single-grain or fixed-number seeding of seeds through a special spoon.

[0003] For example, the patent with the current publication number CN103250491A discloses a seeder, including a seeding wheel, a seeding wheel shaft, a first transmission wheel, a second transmission wheel, a transmission belt, a handle, a seeding cylinder, a seeding cylinder shaft, and a frame. The seeding wheel is installed on the seeding wheel shaft, and the seeding wheel shaft is installed on the frame in front of the seeding cylinder. The first transmission wheel is installed at the end of the seeding wheel shaft, and the second transmission wheel is installed at the end of the seeding cylinder shaft. The first transmission wheel and the second transmission wheel are connected by a transmission belt, and the handle and the seeding cylinder are fixed on the frame.

[0004] Although the above device solves the problem of wide application range of seeding, there are still the following deficiencies: Although it can scoop up seeds through the spoons on the disc, when the machine is walking, vibrations will occur, which will cause the seeds on the spoons to easily vibrate and fall off, resulting in insufficient number of seeds in the hopper, uneven seeding during the walking of the equipment, further leading to inconsistent seeding density and inconvenience. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sowing device for greenhouse vegetable planting to solve the problems raised in the background art and improve the seeding density.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A sowing device for greenhouse vegetable planting, including a seeder body, a power unit connected to the seeder body, a furrowing unit connected below the seeder body, and a depth adjustment unit connected to both sides of the furrowing unit. The seeder body is connected with a seeding unit. The seeding unit includes a plurality of storage cavities and a seed dropping assembly. The seed dropping assembly includes a plurality of inverted hoppers communicating with the bottom of the storage cavities. The bottom of the inverted hopper is fixedly connected with a rectangular frame. A seed receiving ball is rotatably connected inside the rectangular frame. A seed groove is opened inside the seed receiving ball. Two sides of the seed receiving ball are fixedly connected with clamping shafts. The clamping shafts penetrate through the outer ends of the rectangular frame and are fixedly connected with a rotating shaft. One end of the rotating shaft is connected with a speed reduction module in transmission connection with the power unit. A seed bin adjustable structure is connected to the outside of the storage cavity.

[0007] Further, the adjustable structure of the seed bin includes a plurality of side rods and two end rods. On both sides of the outer wall of each storage cavity, a side rod is fixedly connected. At both ends of the plurality of side rods, end rods are fixedly connected. On the bottom surface of each side rod, a chute is provided. The seed dropping components are arranged in multiple groups. On both sides of the outer wall of each inverted hopper in each group of seed dropping components, a slide bar slidably connected to the chute is fixedly connected. The seed groove diameters of the seed receiving balls in the multiple groups of seed dropping components gradually increase from front to back. The ends of the two end rods are connected to the frame of the seeding machine body through a top plate.

[0008] Further, an outer shell is connected to the outside of the deceleration module. An adjusting dial connected to the deceleration module is connected to the outside of the outer shell. The power unit is connected to the deceleration module through a transmission chain. A transmission shaft is fixedly connected to the output shaft of the deceleration module. An insertion rod is fixedly connected to the outside of one end of the transmission shaft passing through the outer shell. A slot corresponding to the insertion rod is provided at one end of the rotating shaft.

[0009] Further, a sliding component is connected between the top plate and the end rod. The sliding component includes a sliding rod and a compression spring. The sliding rod is slidably connected inside the two end rods. The two ends of the two sliding rods are fixedly connected to the top plate. A compression spring is sleeved on the outer walls of the two sliding rods. The two ends of the two compression springs respectively abut against the top plate and the outer wall of the end rod.

[0010] Further, a seed guiding component is installed below each group of seed receiving balls. The seed guiding component includes a plurality of collecting covers. At the bottom of each collecting cover, a blanking hose is fixedly connected. The blanking hose is connected to the furrow unit. A connecting piece is connected to the outside of the plurality of collecting covers.

[0011] Further, the connecting piece includes a plurality of overlapping frames. A peripheral edge is fixedly connected to the top of each collecting cover. The peripheral edge is arranged in an overlapping manner with the overlapping frame. At both ends of the plurality of overlapping frames, a connecting rod fixedly connected to the seeding machine frame is fixedly connected.

[0012] Further, an installation groove is provided on the frame of the seeding machine body. A limiting component is connected to the frame of the seeding machine body. The limiting component includes a U-shaped limiting block. The U-shaped limiting block is located outside the rotating shaft connected to the deceleration module. The U-shaped limiting block is slidably connected in the installation groove. A jacking spring is fixedly connected to the bottom of the U-shaped limiting block. The other end of the jacking spring is connected to the bottom surface of the installation groove.

[0013] Further, a flared opening is fixedly connected to the top of the storage cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This seeding device for greenhouse vegetable planting, through the mutual cooperation of the seed receiving ball, the clamping shaft and the seed groove, ensures that seeds are repeatedly inoculated and discharged from the seed groove of the seed receiving ball under the rotation of the rotating shaft, so that the seeds are discharged one by one. With this setting, compared with the original spoon receiving method, it avoids the problem of empty spoons caused by the vibration of the machine during walking, ensures the seeding density, and improves the seeding efficiency.

[0016] This seeding device for greenhouse vegetable planting is set to be replaceable with the inverted hopper, the rectangular frame and the seed receiving ball, which is convenient for adapting to the seeding of vegetable seeds with different diameters, improves the seeding adaptation range, and reduces the replacement difficulty through the one-time pushing replacement of the seed receiving ball. Compared with the original method of taking out the seed spoon from each spoon tray, it further improves the operation convenience and reduces the operation complexity.

[0017] This seeding device for greenhouse vegetable planting, through the setting of the deceleration module, can adjust the rotation speed of the seed receiving ball by adjusting the rotation speed of the rotating shaft. During the fixed process of traveling, the rotation speed of the rotating shaft determines the rotation speed of the seed receiving ball and the seed discharging speed. Therefore, the deceleration module can be operated by adjusting the dial, so that the drive chain in the power unit is adjusted on the deceleration module to realize the adjustment of the rotation speed of the rotating shaft, and then the plant spacing can be adjusted.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Please refer to Figure 1 - Figure 11 A seeding device for greenhouse vegetable planting, including a seeder body 1, a power unit 9 connected to the seeder body 1, a furrow unit 2 connected to the lower part of 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 with a seeding unit. The seeding unit includes a plurality of storage cavities 4 and a seed dropping assembly. The seed dropping assembly includes a plurality of hoppers 6 communicated with the bottom of the storage cavities 4. The bottom of the hopper 6 is fixedly connected with a rectangular frame 24. A seed receiving ball 25 is rotatably connected in the rectangular frame 24. A seed groove 21 is formed in the seed receiving ball 25. Clamping shafts 26 are fixedly connected to both sides of the seed receiving ball 25. The outer ends of the clamping shafts 26 passing through the rectangular frame 24 are fixedly connected with a rotating shaft 7. One end of the rotating shaft 7 is connected with a deceleration module 8 in transmission connection with the power unit 9. A seed bin adjustable structure is connected to the outside of the storage cavity 4.

[0032] When the seeding device for greenhouse vegetable planting in the present invention is in use, seeds are poured into multiple storage chambers 4. Under the action of gravity, the seeds will enter the inverted hopper 6 and then enter the rectangular frame 24 below the inverted hopper 6. Since the seed receiving balls 25 in the rectangular frame 24 are provided with seed grooves 21, 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 a 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 this set of seed dropping components is driven to rotate around the axis of the clamping shaft 26. When the seed receiving ball 25 rotates until the seed groove 21 faces upward, the seeds located in the rectangular frame 24 will be brought into the seed groove 21. As the rotating shaft 7 rotates, the seed groove 21 of the seed receiving ball 25 is driven to face downward, and the seeds will fall again;

[0033] As the rotating shaft 7 rotates, the seeds matching the seed receiving balls 25 will just fall into the seed grooves 21. As the seed grooves 21 of the seed receiving balls 25 face upward and downward in a cycle, the falling of the seeds is realized;

[0034] 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 grooves 21 of the seed receiving balls 25, and the seeds are discharged one by one. Such a setting avoids the problem of empty spoons caused by the vibration of the machine walking compared with the original spoon receiving, ensures the seeding density, and improves the seeding efficiency.

[0035] As a preferred technical solution of the present invention, the seed bin adjustable structure includes multiple side rods 12 and two end rods 13. Both sides of the outer wall of each storage chamber 4 are fixedly connected with side rods 12, and the two ends of the multiple side rods 12 are fixedly connected with end rods 13. A chute 29 is opened on the bottom surface of each side rod 12. The seed dropping components are arranged in multiple groups. On both sides of the outer wall of each inverted hopper 6 in each group of seed dropping components, there are fixedly connected sliding strips 28 that are slidably connected with the chute 29. The diameters of the seed grooves 21 in the seed receiving balls 25 of multiple groups of seed dropping components increase sequentially from front to back. The ends of the two end rods 13 are connected to the frame of the seeding machine body 1 through a top plate 16.

[0036] Specifically, when seeding, due to the diameter difference of different vegetable seeds, in order to make the seeding machine body 1 adapt to the seeding of seeds with different vegetable diameters, the seed bin adjustable structure can be adjusted;

[0037] Since there are multiple seed dropping components, and the diameters of the seed grooves 21 in each seed receiving ball 25 in each group of seed dropping components are equal, and the diameters of the seed grooves 21 in multiple groups of seed receiving balls 25 increase sequentially from front to back, therefore, each group of seed dropping components can be pushed and replaced according to the seed diameter size;

[0038] When replacing, disconnect this set of seed dropping components from the speed reduction module 8. Then, push the seed dropping component to be replaced, so that the rotating shaft 7 in the seed dropping component to be replaced drives the hopper 6, the rectangular frame 24, and the clamping shaft 26 to move, driving the slide bar 28 on the outer wall of the rectangular frame 24 to move in the chute 29 in the side rod 12, so that the seed dropping component to be replaced corresponds to and communicates with the bottom of the storage cavity 4, and connect the rotating shaft 7 of this seed dropping component to the speed reduction module 8. In this way, when the power unit 9 drives, it will drive the speed reduction module 8 to move and drive the rotating shaft 7 to rotate;

[0039] Since the diameters of the inner seed grooves 21 of the seed receiving balls 25 in each set of seed dropping components increase in sequence, the seed receiving balls 25 after replacement can be used to sow vegetable seeds with different diameters;

[0040] By making the hopper 6, the rectangular frame 24, and the seed receiving balls 25 replaceable, it is convenient to adapt to the sowing of vegetable seeds with different diameters, improving the sowing adaptation range. By pushing and replacing the rotating shaft 7 once, the replacement difficulty can be reduced. Compared with the original method of taking out the seed spoon from each spoon tray, the operation convenience is further improved and the operation complexity is reduced.

[0041] As a preferred technical solution of the present invention, a housing 31 is connected to the outside of the speed reduction module 8. An adjusting dial 10 connected to the speed reduction module 8 is connected to the outside of the housing 31. The power unit 9 is connected to the speed reduction module 8 through a transmission chain. The output shaft of the speed reduction module 8 is fixedly connected with a transmission shaft 11. One end of the transmission shaft 11 passes through the housing 31 and is fixedly connected with a plug rod 30 on the outside. A slot 20 corresponding to the plug rod 30 is opened at one end of the rotating shaft 7.

[0042] Specifically, during sowing, the plant spacing needs to be adjusted. Therefore, when the plant spacing needs to be adjusted, it is only necessary to make the rotation speed of the seed receiving ball 25 adjustable according to the rotation speed of the rotating shaft 7. During a fixed progress, the rotation speed of the rotating shaft 7 determines the rotation speed of the seed receiving ball 25 and determines the seed discharging speed. Therefore, the speed reduction module 8 can be operated through the adjusting dial 10 to adjust the transmission chain in the power unit 9 on the speed reduction module 8 to realize the adjustment of the rotation speed of the rotating shaft 7;

[0043] In the above structure, using the adjusting dial 10 to adjust the rotation speed of the rotating shaft 7 of the speed reduction module 8 should be an existing mature technology, just like the gear speed adjustment principle in a mountain bike. Therefore, it is not further elaborated in detail here.

[0044] As a preferred technical solution of the present invention, a sliding assembly is connected between the top plate 16 and the end rod 13. The sliding assembly includes a sliding rod 22 and a compression spring 23. The sliding rod 22 is slidably connected inside the two end rods 13. Both 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 compression springs 23. Both ends of the two compression springs 23 are abutted against the outer walls of the top plate 16 and the end rod 13 respectively.

[0045] Specifically, when adjusting each seed dropping assembly, the rotating shaft 7 can be smoothly disengaged from the transmission shaft 11 on the speed reduction module 8. During operation, the end rod 13 can be pulled first to drive the end rod 13 to slide outside the sliding rod 22. Since the storage cavity 4 is fixedly connected to the side rod 12, when the end rod 13 slides outside the sliding rod 22, the end rod 13 drives the side rod 12, the storage cavity 4, and the seed dropping assembly to move simultaneously. When the seed dropping assembly moves, it will drive the slot 20 at the end of the rotating shaft 7 in the seed dropping assembly to be replaced to disengage from the insertion rod 30 at the end of the transmission shaft 11 of the speed reduction module 8.

[0046] After disengagement, the seed dropping assembly to be replaced is pushed to move from the frame of the seeding machine body 1, so that the inverted hopper 6 in the seed dropping assembly is located below the bottom of the storage cavity 4. At this time, the end rod 13 is restored, and under the action of the compression spring 23, the end rod 13 is reset.

[0047] When the end rod 13 is reset, it drives the side rod 12, the storage cavity 4, the slide bar 28, the inverted hopper 6, the rectangular frame 24, the seed receiving ball 25, and the rotating shaft 7 to be reset and slide towards one end of the transmission shaft 11 on the speed reduction module 8. At this time, the slot 20 on the rotating shaft 7 can be inserted into the insertion rod 30 to complete the limit.

[0048] Since the compression spring 23 is provided outside the sliding rod 22, when the seed dropping assembly drops seeds normally, the acting force of the compression spring 23 can ensure that the rotating shaft 7 and the transmission shaft 11 are always not disengaged.

[0049] As a preferred technical solution of the present invention, a seed guiding assembly is installed below each group of seed receiving balls 25. The seed guiding assembly includes a plurality of collecting covers 14. A blanking hose 15 is fixedly connected to the bottom of each collecting cover 14. The blanking hose 15 is connected to the furrowing unit 2. A connecting member is connected to the outside of the plurality of collecting covers 14.

[0050] Specifically, in order to facilitate the export of seeds to the ground after they fall, the collecting cover 14 is used. When the seed dropping assembly is replaced and adjusted, the collecting cover 14 is always located below to ensure the guiding of the seeds.

[0051] The blanking hose 15 is a hose, which can meet the spacing adjustment of the furrowing unit 2 and facilitate the adjustment of the row spacing.

[0052] It should be noted that both the depth adjustment unit 3 and the furrow unit 2 are existing mature technologies and have not been improved. The structure of the present application can also meet the adjustment of the depth adjustment unit 3 and the furrow unit 2.

[0053] As a preferred technical solution of the present invention, the connecting member includes a plurality of overlapping frames 18. A surrounding edge 17 is fixedly connected to the top of each collecting cover 14. The surrounding edge 17 is arranged to overlap with the overlapping frame 18. Connecting rods 19 fixedly connected to the sowing machine frame are fixedly connected to both ends of the plurality of overlapping frames 18.

[0054] Specifically, in order to facilitate the installation of the collecting cover 14, the surrounding edge 17 on the outside of the collecting cover 14 can be placed on the overlapping frame 18, which is convenient for the installation of the collecting cover 14.

[0055] As a preferred technical solution of the present invention, an installation groove 33 is provided on the frame of the sowing machine body 1. A limiting component is connected to the frame of the sowing machine body 1. The limiting component includes a U-shaped limiting block 32. The U-shaped limiting block 32 is located outside the rotating shaft 7 connected to the deceleration module 8. The U-shaped limiting block 32 is slidably connected in the installation groove 33. A jacking spring 27 is fixedly connected to the bottom of the U-shaped limiting block 32. The other end of the jacking spring 27 is connected to the bottom surface of the installation groove 33.

[0056] 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 limiting block 32, and the next rotating shaft 7 will enter the U-shaped limiting block 32. Under the action of the jacking spring 27, the U-shaped limiting block 32 ensures that the height of the U-shaped limiting block 32 remains unchanged and always limits the rotating rotating shaft 7.

[0057] As a preferred technical solution of the present invention, a flared opening 5 is fixedly connected to the top of the storage cavity 4.

[0058] Specifically, the setting of the flared opening 5 facilitates the dumping of seeds.

[0059] In the above structure, the power unit 9 is an existing technology. Driving the rotating shaft 7 to rotate through a transmission chain and the deceleration module 8 are all existing mature technologies, so no detailed description will be given here.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
