DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] Depend on Figure 1-4 A vegetable seeder with adjustable sowing spacing is provided, comprising a frame 1; a seed box 2 is supported and arranged on the frame 1;

[0027] The seed box 2 is a rectangular box structure and has a storage cavity formed inside for storing vegetable seeds;

[0028] A feeding hole is provided in the seed box 2, and a feeding box 4 is installed at the bottom of the seed box 2. The top of the feeding box 4 has an opening and is connected to the seed box 2;

[0029] The feed box 4 is connected with a seed tube 3;

[0030] The frame 1 is provided with a fan 7, and an extended air duct 71 is provided at the air outlet of the fan 7;

[0031] The seed tube 3 is arranged vertically and extends into the extended air duct 71;

[0032] The other end of the extended air duct 71 is connected to a discharge pipe 8; a plurality of inner baffles 82 are arranged in the discharge pipe 8 at intervals, and the plurality of inner baffles 82 are arranged in an arc shape and a distance is formed between two adjacent inner baffles 82;

[0033] Locking components 9 are provided on the upper and lower wall surfaces of the extended air duct 71 and the discharge pipe 8 ; the locking components 9 are provided at the connection between the extended air duct 71 and the discharge pipe 8 .

[0034] In the present embodiment, in actual use, the two sets of locking components 9 can be used to quickly lock the discharge pipe 8 and the extended air duct 71, thereby realizing the connection between the two. When the user needs to sow vegetable seeds, by driving the reduction motor 6 and the fan 7, and cooperating with the spiral blades 5 to convey the seeds, the airflow generated by the fan 7 can evenly distribute the seeds into the discharge pipe 8, and accurately sow them to various positions in the field through the air duct formed by the inner partition 82, thereby ensuring uniform distribution of seeds and improving sowing quality. At the same time, by adjusting the wind speed of the fan 7 and the spacing distance of the inner partition 82, the sowing spacing of the seeds can also be accurately controlled, thereby meeting the sowing requirements of different types of vegetables and improving the survival rate and uniformity of the seeds. Compared with traditional seeders, the seeder of the present application not only adjusts the spacing of the seeds for sowing, but also has a low overall use cost, and is more suitable for small-area planting.

[0035] It should be further explained that, in actual use, a plurality of inner partitions 82 arranged in the discharge pipe 8 are spaced apart to form an air duct for the spread of vegetable seeds. When the fan 7 is driven, the fast airflow generated by the fan 7 can quickly transport a large number of vegetable seeds to the outlet of the inner partition 82, and discharge them through the discharge pipe 8 to complete the sowing. During this period, the spacing of the inner partitions 82 is related to the sowing spacing of the seeds. Taking into account the sowing spacing requirements of different seeds, the user can prefabricate the discharge pipe 8 with a variety of spacing types, and by changing the number and spacing interval of the inner partitions 82 in the discharge pipe 8, thereby achieving the sowing of vegetable seeds with different spacings.

[0036] Furthermore, considering the prefabrication cost and portability issues, the discharge pipe 8 and the inner partition 82 can be made of plastic as a whole, which is relatively light and has a low production cost. It can be customized using plastic sheets according to the needs of users.

[0037] It should be noted that, considering that the vegetable seeder of the present application needs to be moved between fields during use, in a preferred embodiment, the user can mount the frame 1 on a vehicle carrier such as a mobile tricycle, thereby realizing mobile sowing of the seeder of the present application.

[0038] Specifically, refer to Figure 4The two sets of locking components 9 include two positioning seats 91 arranged on the wall surface of the connection between the extended air duct 71 and the discharge pipe 8, a mounting plate 92 is installed between the two positioning seats 91, a positive and negative threaded rod 93 is rotatably arranged between the two positioning seats 91, and two slider seats 95 are engaged with the outside of the positive and negative threaded rod 93, and the two slider seats 95 are respectively engaged with one of the threads of the positive and negative threaded rod 93; one end of the positive and negative threaded rod 93 passes through the positioning seat 91 and is extended to be connected with a rotating shaft handle 94.

[0039] In this embodiment, in actual use, the user rotates the rotating shaft handle 94, and the forward and reverse screw rods 93 connected thereto can rotate synchronously. When the forward and reverse screw rods 93 are rotating, they are limited by the positioning seat 91 and the forward and reverse tooth limits on the forward and reverse screw rods 93. At this time, the two slider seats 95 engaged on the outside of the forward and reverse screw rods 93 will move in opposite directions or in reverse directions.

[0040] Furthermore, in order to improve the rotation smoothness of the forward and reverse threaded rod 93, a bearing member is also assembled in the positioning seat 91, and both ends of the forward and reverse threaded rod 93 are rotatably matched with the bearing member.

[0041] Specifically, refer to Figure 2 and Figure 4 The lower end surfaces of the two slider seats 95 are integrally provided with a bite plate 96, and the opposite side surfaces of the two bite plates 96 are provided with a plurality of bite teeth 97; the upper and lower side walls of the extended air duct 71 and the discharge pipe 8 are integrally provided with positioning blocks 81.

[0042] In this embodiment, when the positive and negative threaded rods 93 are rotating, the two slider seats 95 meshed with the outside of the positive and negative threaded rods 93 will move in opposite directions or in opposite directions;

[0043] The user drives the two slider seats 95 to move toward each other until the two bite plates 96 are tightly against the positioning block 81. At this time, the bite teeth 97 arranged on the side of the bite plates 96 can be tightly engaged with the side wall of the positioning block 81. In a more preferred embodiment, the user can also engrave a protrusion on the side of the positioning block 81 that is compatible with the bite teeth 97, thereby further achieving close contact between the bite teeth 97 and the positioning block 81. When the two bite plates 96 clamp the two positioning blocks 81 therebetween, the locking between the extended air duct 71 and the discharge pipe 8 can be achieved by using two sets of locking components 9.

[0044] Furthermore, compared with the traditional bolt-type or welding-type assembly, the provided locking assembly 9 can provide greater flexibility in the connection between the discharge pipe 8 and the extended air duct 71 , making it easier for the user to quickly connect and assemble the extended air duct 71 and the discharge pipe 8 .

[0045] Specifically, refer to Figure 1-4A spiral blade 5 is rotatably arranged in the material box 4 , and a reduction motor 6 is assembled on the outer wall of the material box 4 . The output end of the reduction motor 6 passes through the material box 4 and is connected to one end of the spiral blade 5 .

[0046] In this embodiment, after the extended air duct 71 and the discharge pipe 8 are connected, the user connects the power supply to the fan 7 and the reduction motor 6, so that the reduction motor 6 can drive the spiral blade 5 to rotate. Then the user pours the vegetable seeds to be sown into the seed box 2. At this time, the vegetable seeds are limited by the cover plate 21, so that they can slowly flow into the lower material box 4. Then, the spiral blade 5 is used for rotation transmission, so that the vegetable seeds can be evenly transported to the seed tube 3, and then transmitted to the fan 7 through the seed tube 3, completing the transmission of the vegetable seeds.

[0047] The utility model discloses a vegetable seeder with adjustable sowing spacing:

[0048] Step 1: In actual use, when the user needs to use the seed drill to sow vegetable seeds, firstly, the discharge pipe 8 and the extended air duct 71 are connected, and then the two sets of locking components 9 can be driven to lock the two;

[0049] The second step: during this period, the user brings one end of the discharge pipe 8 into contact with the extended air duct 71. At this time, the two positioning blocks 81 arranged on the discharge pipe 8 and the extended air duct 71 will be in an adjacent state. Then the user places the two sets of locking components 9 on the upper and lower sides of the discharge pipe 8 and the extended air duct 71 respectively, and rotates the shaft handle 94 so that the forward and reverse screw rods 93 connected thereto can rotate synchronously. When the forward and reverse screw rods 93 are rotating, they are limited by the positioning seat 91 and the forward and reverse tooth limit on the forward and reverse screw rods 93. At this time, the two slider seats 95 engaged with the outside of the forward and reverse screw rods 93 will move in opposite directions or in reverse directions. The user drives the two slider seats 95 to move in opposite directions until the two bite plates 96 are tightly against the positioning blocks 81. At this time, the locking between the extended air duct 71 and the discharge pipe 8 can be completed by using the two sets of locking components 9;

[0050] Step 3: After the extended air duct 71 and the discharge pipe 8 are connected, the user connects the power supply to the fan 7 and the reduction motor 6 so that the reduction motor 6 can drive the spiral blade 5 to rotate. Then the user pours the vegetable seeds to be sown into the seed box 2. The vegetable seeds are limited by the cover plate 21 so that they can slowly flow into the lower material box 4. Then, the spiral blade 5 is used to transmit the vegetable seeds evenly to the seed tube 3 and fall into the extended air duct 71 through the seed tube 3. At this time, the vegetable seeds that fall into the extended air duct 71 are blown into the discharge pipe 8 by the wind force of the fan 7. Finally, they are separated by the inner partition 82 to complete the propagation of the vegetable seeds.

[0051] Although the 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.
