[0002] Seeders are planting machines that sow crop seeds. They are used for a certain type of crop and are often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, and forage spreaders. In the field of vegetable planting, the most common planting methods are seedling transplanting and direct sowing. Currently, the most common methods are manual sowing or machine sowing. However, the current seeders are relatively complex in structure and are all automated structures with high costs, which are not conducive to sowing on small and medium-sized lands, especially in my country's planting environment, making the equipment difficult to popularize. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a vegetable seeder, which solves the problems that the seeders in the prior art are all large machines that are not suitable for small operations, and that manual sowing is labor-intensive and has low sowing efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0006] By adopting the above structural design, the vegetable seeder can adapt to small-scale sowing operations, and can automatically and quantitatively feed the seeds into the feeding mechanism below and send the seeds into the soil to complete sowing through the rotation of the feeding cylinder and the sealing cylinder, thereby improving the sowing efficiency.

[0007] Preferably, the vehicle body is a double-layer structure, including an upper plate and a lower plate, the silo is fixedly mounted on the upper plate, a through hole is penetrated through the lower plate, and a feeding mechanism connected below the silo passes through the through hole and is fixedly connected to the silo.

[0008] The above structural design and the upper and lower layers of the vehicle body facilitate the integrated installation of the drive mechanism.

[0009] Preferably, the feeding mechanism includes a fixed cylinder and a movable cylinder, the movable cylinder is sleeved outside the fixed cylinder, one side of the movable cylinder is connected to the rotating shaft of the feeding cylinder protruding outside the silo through an eccentric wheel connecting rod assembly, and the rotation of the fixed cylinder drives the eccentric wheel connecting rod assembly to move up and down, thereby driving the movable cylinder to move up and down.

[0010] By adopting the above-mentioned structural design, the seeds in the feeding mechanism can be directly sent into the soil to complete the sowing through the up and down movement of the movable cylinder of the feeding mechanism, and there is no need to make nests manually. The seeds can be directly inserted into the soil by the movable cylinder moving downward. The insertion depth is adjustable and can be adjusted according to the sowing needs. The consistency of the insertion depth can be ensured, thereby improving the germination rate and survival rate of the seeds.

[0033] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] See also Figures 1 to 4A vegetable seeding machine includes a vehicle body 1, a wheel 2 is provided at the lower end of the vehicle body 1, and the wheel 2 is driven by a driving mechanism 3. The specific structure is as follows: the wheels 2 at the front and rear ends are fixedly connected by rotating a rotating shaft 11 arranged on the vehicle body 1, and the wheels 2 can be replaced according to needs. Among them, the driving mechanism 3 includes a driving motor 3a installed on the vehicle body 1, a driving wheel 3c is provided at the output end of the driving motor 3a, and a driven wheel 3d is correspondingly provided on the connecting shaft 11, and the driving wheel 3c is connected to the driven wheel 3d on the connecting shaft 11 through a belt 3b. In this embodiment, the diameter of the driving wheel 3c is smaller than the diameter of the driven wheel 3d, and the transmission efficiency of the driving motor 3a can be improved by the transmission ratio. A silo 4 is provided at the upper end of the vehicle body 1, and the lower part of the silo 4 is a conical structure, and the lower part is through-set, and the lower part of the silo 4 is connected to a feeding mechanism 5 that can move up and down, and the silo 4 transmits the seeds downward to the feeding mechanism 5 and sends them into the soil through the feeding mechanism 5 to complete the sowing. A feeding cylinder 6 and a sealing cylinder 7 matched with the feeding cylinder 6 are arranged in the silo 4. One end of the feeding cylinder 6 and the sealing cylinder 7 are matched with a gear set 8, and the gear set 8 is driven to rotate by a motor 9 arranged on one side.

[0037] The specific structure is as follows:

[0038] The vehicle body 1 is a double-layer structure, including an upper plate 1a and a lower plate 1b. The silo 4 is fixedly mounted on the upper plate 1a. A through hole 1c is penetrated through the lower plate 1b. The feeding mechanism 5 connected below the silo 4 passes through the through hole 1c and is fixedly connected to the silo 4.

[0039] The feeding mechanism 5 includes a fixed cylinder 5a and a movable cylinder 5b. The upper end of the fixed cylinder 5a is fixedly mounted on the lower end of the silo 4, and the movable cylinder 5b is sleeved outside the fixed cylinder 5a. One side of the movable cylinder 5b is connected to the rotating shaft of the feeding cylinder 6 protruding outside the silo 4 through the eccentric wheel connecting rod assembly 5c. The rotation of the fixed cylinder 5a drives the eccentric wheel connecting rod assembly 5c to move up and down, thereby driving the movable cylinder 5b to move up and down. The seeds inside the movable cylinder 5b are sent into the soil through the up and down movement of the movable cylinder 5b, and then it automatically rises after sowing. The lower end of the movable cylinder 5b is movably provided with an openable and closable conical mouth 5d. When the movable cylinder 5b is pulled up, the conical mouth 5d can automatically open and release the seeds inside to complete sowing.

[0040] Further, the eccentric wheel connecting rod assembly 5c includes a first connecting rod 51c, a second connecting rod 52c, a third connecting rod 53c and an eccentric wheel 54c, one end of the first connecting rod 51c is fixedly connected to one side of the movable cylinder 5b, and the other end is rotatably connected to the second connecting rod 52c arranged vertically, the upper end of the second connecting rod 52c is rotatably connected to the third connecting rod 53c, the other end of the third connecting rod 53c is rotatably connected to the eccentric wheel 54c, and the other end of the eccentric wheel 54c is fixedly connected to the rotating shaft of the feeding cylinder 6 protruding outside the silo 4. The eccentric wheel connecting rod assembly 5c in the present invention is connected to the movable cylinder 5b below, and the feeding cylinder 6 is connected to the rotating shaft outside the silo 4 above, and then driven by the driving mechanism 3 that drives the feeding cylinder 6 to rotate, without using a driving mechanism alone, so that the equipment structure is simpler, the manufacturing cost is lower, and the stability is stronger when walking in the mountains.

[0041] The feed tube 6 is provided with a plurality of groups of grooves 6a at intervals, and the blocking tube 7 is provided with a blocking brush 7a corresponding to the grooves 6a. The feed tube 6 and the blocking tube 7 are rotatably mounted on the silo 4 via a rotating shaft, and the gear set 8 includes a first driven gear 8a and a second driven gear 8b meshing with each other, and the first driven gear 8a and the second driven gear 8b are respectively fixedly mounted on the feed tube 6 and the blocking tube 7 on the rotating shaft protruding outside the silo 4, and the second driven gear 8b is meshed with a driving gear 8c provided on the motor 9. In the present invention, since the gap between the feed tube 6 and the surrounding structure is small, the seeds cannot be fed into the feeding mechanism 5 below. If the gap is designed to be large, the amount of seeds discharged cannot be accurately controlled. Therefore, by providing grooves 6a on the feed tube 6, the seeds are quantitatively brought to the bottom and enter the feeding mechanism 5, so that the seed sowing amount can be accurately completed.

[0042] In this embodiment, the blocking brush 7a is made of soft material, which can avoid the problem of seed damage in the Fengdu groove. The gap between the feeding tube 6 and the blocking tube 7 and the silo 4 is 0.5-1mm.

[0043] Example 2

[0044] See also Figure 5 The other structures of this embodiment are the same as those of the embodiment, and the difference lies in that a scraper plate 10 is provided on the silo 4 above the plugging cylinder 7, one end of the scraper plate 10 is rotatably mounted on the silo 4, and the other end is provided above the feeding cylinder 6 with a gap of 0.5-1mm. The structure of this embodiment is mainly for vegetable seeds with smaller particles. Since the particles are smaller, they are easy to fall from the gap of the plugging brush 7a of the plugging cylinder 7. Therefore, a scraper plate 10 is provided above the plugging cylinder 7 for shielding, which can prevent the seeds from leaking directly from the gap between the plugging brushes, and ensure that the seeds are quantitatively fed into the feeding mechanism 5 through the groove 6a on the feeding cylinder 6.

[0045] Working principle of the present invention:

[0046] Before using the seeder, the land for sowing needs to be turned over in advance. When the vegetable seeder is working, first choose whether to install the scraper plate 10 according to the size of the vegetable seeds. If the vegetable seeds are larger in size, use the method of Example 1. Pour the seeds into the silo 4 manually. Since the connection gap around the feeding tube 6 and the blocking tube 7 is small, the seeds will not fall automatically. Start the seeder, the driving mechanism 3 works, and the driving motor 3a drives the wheel 2 to rotate to realize the automatic advancement of the seeder. Then, the motor 9 works at the same time, and the motor 9 drives the gear set 8 to rotate, thereby driving the feeding tube 6 and the blocking tube 7 to rotate. When the feeding tube 6 rotates, the groove 6a of the feeding tube 6 is filled with vegetable seeds. At the same time, the blocking brush 7a on the blocking tube 7 rotating in the opposite direction blocks the seeds in the groove 6a to ensure that they will not leak out during the rotation process. When the feeding cylinder 6 turns to the lower position and disengages from the blocking cylinder 7, the seeds in the groove 6a of the feeding cylinder 6 automatically fall into the feeding mechanism 5, and the feeding mechanism 5 drives the movable cylinder 5b to move downward into the soil through the eccentric wheel connecting rod assembly 5c, thereby sending a certain amount of seeds into the soil to complete the sowing.
