Description

Technical Field

[0001] This utility model relates to the field of sowing device technology, and specifically discloses a sowing device for vegetable seedling cultivation. Background Technology

[0002] Vegetables refer to a class of plants or fungi that can be cooked and eaten. Vegetables are an essential part of people's daily diet. Vegetables can provide the human body with a variety of essential vitamins and minerals. When cultivating vegetable seedlings, vegetable seeds need to be sown using a sowing device.

[0003] A vegetable seedling sowing device, disclosed in Chinese Patent No. CN221634385U, includes a sowing tray and a rotating shaft running through it. Several sowing grooves are arranged around the sowing tray. Rollers are fixed at both ends of the rotating shaft, which has a rotatable connector. A U-shaped sowing tray, fitted against both sides of the sowing tray, is located at the other end of the connector.

The multiple seed-feeding chambers are rotatably connected to a first rotating shaft. The outer wall of the first rotating shaft is fixedly connected to a feeding roller located inside the multiple seed-feeding chambers. The outer wall of the feeding roller has a collection groove. The lower end face of the outer shell has a notch located below the movable block. The lower end face of the movable block is fixedly connected to multiple seed guide cylinders that communicate with the multiple seed-feeding chambers and pass through the notch. The lower end of the seed guide cylinder is rotatably connected to two symmetrically distributed and mutually matched sowing nozzles through a hinge.

A second rotating shaft is rotatably connected to the inside of the outer shell via a fixed plate. One end of the second rotating shaft is fixedly connected to a cam that abuts against the upper surface of the contact plate. The other end of the second rotating shaft is fixedly connected to a first bevel gear. A third rotating shaft is rotatably connected to the lower end of the inside of the outer shell. The other end of the third rotating shaft is fixedly connected to a second bevel gear that meshes with the first bevel gear. A plurality of evenly distributed vertical plates are fixedly connected to the lower end of the outer shell. The plurality of vertical plates are grouped in pairs. A fourth rotating shaft is rotatably connected between each group of vertical plates. Rollers are fixedly connected to the outer walls of the two fourth rotating shafts. A third bevel gear is fixedly connected to the outer wall of the fourth rotating shaft located on the left side. One end of the third rotating shaft extends to the outside of the outer shell and is fixedly connected to a fourth bevel gear that meshes with the third bevel gear.

[0011] As a preferred embodiment of the vegetable seedling sowing device of this utility model, the lower end face of the outer shell is fixedly connected to two vertical rods located on both sides of the notch, and the lower ends of the two vertical rods are fixedly connected to a horizontal plate. The opposite side walls of the two sowing nozzles are fixedly connected to inclined plates that abut against the horizontal plates, and the two inclined plates are fixedly connected to the outer wall of the seed guide cylinder with a first spring.

[0012] As a preferred embodiment of the vegetable seedling sowing device of this utility model, one end of the first rotating shaft extends to the outside of the moving block and is fixedly connected to a gear, and the rear end of the inner shell is fixedly connected to a rack that meshes with the gear.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A seeding device for vegetable seedling cultivation includes an outer shell 1, and a seeding mechanism is provided inside the outer shell 1;

[0028] The sowing mechanism includes a movable block 2 disposed inside the outer casing 1. The movable block 2 has multiple seed storage chambers 3 distributed front to back. The lower end of the movable block 2 has a seed lowering chamber 4 that communicates with the multiple seed storage chambers 3. The multiple seed lowering chambers 4 are rotatably connected to a first rotating shaft 5. The outer wall of the first rotating shaft 5 is fixedly connected to a feeding roller 6 located inside the multiple seed lowering chambers 4. The outer wall of the feeding roller 6 has a collection groove 7. The lower end face of the outer casing 1 has a notch 8 located below the movable block 2. The lower end face of the movable block 2 is fixedly connected to multiple seed guide cylinders 9 that communicate with the multiple seed lowering chambers 4 and pass through the notch 8. The lower end of the seed guide cylinder 9 is rotatably connected to two symmetrically distributed and mutually matched sowing nozzles 10 through a hinge seat.

[0029] In this embodiment: during use, vegetable seeds are first added to multiple seed storage chambers 3 through multiple seed passage pipes 33 and seed inlet troughs 23, and then the vegetable seeds enter multiple collection troughs 7. The number of vegetable seeds entering the collection troughs 7 is three to five. Then, the outer shell 1 is moved manually. During the movement, the moving block 2 moves downward. The moving block 2, together with multiple seed guide cylinders 9, drives multiple seeding nozzles 10 to move downward, so that the multiple seeding nozzles 10 are inserted into the ground. At the same time as the downward movement, the first rotating shaft 5 rotates, and the first rotating shaft 5 drives multiple feeding rollers 6 to rotate 180 degrees, so that the multiple collection troughs 7 rotate so that the openings face downward, thereby making the multiple collection troughs 7... Vegetable seeds are fed into multiple seed guide cylinders 9, and then multiple seeding nozzles 10 are opened to discharge the vegetable seeds from the seed guide cylinders 9 to the ground. Then, the moving block 2 moves upward, which drives the multiple seed guide cylinders 9 and multiple seeding nozzles 10 to reset. At the same time, the first rotating shaft 5 and multiple feeding rollers 6 rotate in opposite directions to reset, causing multiple collection troughs 7 to rotate to face upward, and allowing other vegetable seeds to enter the multiple collection troughs 7. Then, the above steps are repeated for sowing again, so that multiple rows of vegetable seeds can be sown at once through multiple seed guide cylinders 9 and multiple seeding nozzles 10, which effectively improves sowing efficiency.

[0030] During the sowing process, the ground is leveled by scraping the inclined plate 24 after sowing, and the soil pits after sowing are covered with soil, which effectively reduces the labor burden of workers.

[0031] As a technical optimization of this utility model, the left side wall of the movable block 2 is fixedly connected to an abutment plate 11. The inside of the outer shell 1 is rotatably connected to a second rotating shaft 12 via a fixed plate. One end of the second rotating shaft 12 is fixedly connected to a cam 13 that abuts against the upper surface of the abutment plate 11. The other end of the second rotating shaft 12 is fixedly connected to a first bevel gear 14. The lower end of the inside of the outer shell 1 is rotatably connected to a third rotating shaft 15. The other end of the third rotating shaft 15 is fixedly connected to a second bevel gear 16 that meshes with the first bevel gear 14. The lower end of the outer shell 1 is fixedly connected to multiple evenly distributed vertical plates 17. The multiple vertical plates 17 are grouped in pairs. Each group of vertical plates 17 is rotatably connected to a fourth rotating shaft 18. The outer walls of the two fourth rotating shafts 18 are fixedly connected to rollers 19. The outer wall of the fourth rotating shaft 18 on the left side is fixedly connected to a third bevel gear 20. One end of the third rotating shaft 15 extends to the outside of the outer shell 1 and is fixedly connected to a fourth bevel gear 21 that meshes with the third bevel gear 20.

[0032] In this embodiment: the outer shell 1 moves via multiple rollers 19, which in turn drive two fourth rotating shafts 18 to rotate. Simultaneously, the fourth rotating shaft 18 on the left side drives the third bevel gear 20 to rotate. The third bevel gear 20, in conjunction with the fourth bevel gear 21, drives the third rotating shaft 15 to rotate. The third rotating shaft 15, in conjunction with the second bevel gear 16 and the first bevel gear 14, drives the second rotating shaft 12 to rotate. The second rotating shaft 12 drives the cam 13 to rotate. Through the interaction between the rotating cam 13 and the abutment plate 11, the moving block 2 moves downward.

[0033] As a technical optimization of this utility model, two vertical rods 22 located on both sides of the notch 8 are fixedly connected to the lower end face of the outer shell 1. A horizontal plate 25 is fixedly connected to the lower end of each of the two vertical rods 22. An inclined plate 26 that abuts against the horizontal plate 25 is fixedly connected to the side wall of each of the two sowing nozzles 10 facing away from each other. A first spring 27 is fixedly connected between each of the two inclined plates 26 and the outer wall of the seed guide cylinder 9.

[0034] In this embodiment: as the seed guide tube 9 moves the two seeding nozzles 10 downward, the two seeding nozzles 10 move the two inclined plates 26 downward. Since the two horizontal plates 25 abut against the two inclined plates 26, the two seeding nozzles 10 can rotate around the hinge seat through the mutual cooperation between the two horizontal plates 25 and the two inclined plates 26. At the same time, the two inclined plates 26 compress the two first springs 27 to contract, so that the two first springs 27 generate a rebound force, thereby opening the two seeding nozzles 10.

[0035] As the seed guide tube 9 moves the two seeding nozzles 10 upward, the two first springs 27 rebound, and the two first springs 27 push the two seeding nozzles 10 to rotate in opposite directions, causing the two seeding nozzles 10 to come into contact and thus close.

[0036] As a technical optimization of this utility model, one end of the first rotating shaft 5 extends to the outside of the moving block 2 and is fixedly connected to a gear 28, and the rear end of the inner shell 1 is fixedly connected to a rack 29 that meshes with the gear 28.

[0037] In this embodiment: when the moving block 2 moves downward, the moving block 2 drives the gear 28 to move downward. Since the gear 28 is meshed with the rack 29, the first rotating shaft 5 can be driven to rotate through the mutual cooperation between the gear 28 and the rack 29.

[0038] As a technical optimization of this utility model, two sliding rods 30 distributed front and back are fixedly connected inside the outer shell 1. A connecting block 31 that is slidably connected to the two sliding rods 30 is fixedly connected to the right side wall of the moving block 2. Two second springs 32 that are respectively sleeved on the outer walls of the two sliding rods 30 are fixedly connected between the connecting block 31 and the outer shell 1.

[0039] In this embodiment: the two slide bars 30 can limit the movement of the moving block 2, so that the moving block 2 can move smoothly. At the same time, the two second springs 32, together with the connecting block 31, can push the moving block 2 to move upward and reset.

[0040] As a technical optimization of this utility model, the moving block 2 and the outer shell 1 are fixedly connected by a seed passage pipe 33 that communicates with multiple seed storage chambers 3 respectively. The upper end face of the outer shell 1 is fixedly connected by a seed inlet groove 23 that communicates with multiple seed passage pipes 33 respectively. The section of the seed passage pipe 33 between the moving block 2 and the outer shell 1 is a telescopic flexible hose structure.

[0041] In this embodiment, vegetable seeds can be easily added to the seed storage chamber 3 through the seed inlet trough 23 and the seed passage pipe 33. Since the section of the seed passage pipe 33 between the moving block 2 and the outer shell 1 is a telescopic flexible hose structure, the seed passage pipe 33 can extend and retract with the movement of the moving block 2, preventing the seed passage pipe 33 from affecting the movement of the moving block 2.

[0042] As a technical optimization of this utility model, a leveling plate 24 is fixedly connected to the right side of the lower end face of the outer shell 1, and the lower end of the leveling plate 24 is flush with the lower end of the outer wall of the roller 19.

[0043] In this embodiment, the ground after sowing can be leveled by the leveling sloping plate 24, and the soil pits after sowing can be covered with soil, effectively reducing the labor burden of workers.

[0044] Working principle and usage process of this utility model:

[0045] In use, vegetable seeds are first added to multiple seed storage chambers 3 through multiple seed pipes 33 and seed inlet troughs 23, and then the vegetable seeds are placed into multiple collection troughs 7. The number of vegetable seeds in each collection trough 7 is three to five. Then, the outer shell 1 is moved by manpower, and the outer shell 1 is moved by multiple rollers 19. The multiple rollers 19 drive two fourth rotating shafts 18 to rotate. At the same time, the fourth rotating shaft 18 on the left drives the third bevel gear 20 to rotate. The third bevel gear 20, in conjunction with the fourth bevel gear 21, drives the third rotating shaft 15 to rotate. The third rotating shaft 15, in conjunction with the second bevel gear 16 and the first bevel gear 14, drives the second rotating shaft 12 to rotate. The second rotating shaft 12 drives the cam 13 to rotate. Through the interaction between the rotating cam 13 and the abutment plate 11, the moving block 2 is moved downward. The moving block 2, in conjunction with multiple seed guide cylinders 9, drives multiple seeding nozzles 10 to move downward, so that the multiple seeding nozzles 10 are inserted into the ground.

[0046] As the block moves downward, the moving block 2 drives the gear 28 to move downward. Since the gear 28 is meshed with the rack 29, the gear 28 and the rack 29 work together to drive the first rotating shaft 5 to rotate. The first rotating shaft 5 drives multiple feeding rollers 6 to rotate 180 degrees, causing multiple collecting troughs 7 to rotate downward. This allows the vegetable seeds in the multiple collecting troughs 7 to enter multiple seed guide cylinders 9. At the same time, as the seed guide cylinders 9 drive the two seeding nozzles 10 to move downward, the two seeding nozzles 10 drive the two inclined plates 26 to move downward. Since the two horizontal plates 25 abut against the two inclined plates 26, the two seeding nozzles 10 work together to drive the two seeding nozzles 10 to rotate around the hinge. At the same time, the two inclined plates 26 compress the two first springs 27 to contract, causing the two first springs 27 to generate a rebound force, which in turn causes the two seeding nozzles 10 to open, discharging the vegetable seeds in the multiple seed guide cylinders 9 into the ground through the opened seeding nozzles 10.

[0047] When the cam 13 rotates 180 degrees, the two second springs 32, in conjunction with the connecting block 31, push the moving block 2 upward to reset. The moving block 2 drives multiple seed guide cylinders 9 and multiple sowing nozzles 10 to reset. At the same time, through the mutual cooperation between the gear 28 and the rack 29, the first rotating shaft 5 and multiple feeding rollers 6 are driven to rotate in the opposite direction to reset, so that multiple collection troughs 7 rotate to face upward, and other vegetable seeds enter the multiple collection troughs 7 respectively. Then, the above steps are repeated for sowing again. Thus, multiple rows of vegetable seeds are sown at one time through multiple seed guide cylinders 9 and multiple sowing nozzles 10, which effectively improves the sowing efficiency.

[0048] During the sowing process, the ground is leveled by scraping the inclined plate 24 after sowing, and the soil pits after sowing are covered with soil, which effectively reduces the labor burden of workers.
