DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-Figure 10 , which is the first embodiment of the present invention, and this embodiment provides a seeder with adjustable sowing spacing. The seeder with adjustable sowing spacing includes a sowing assembly 100, including a storage box 101, a fixing frame 102 is arranged below the storage box 101, a turntable 103 is arranged in the fixing frame 102, an air hood 104 is fixed to one side of the fixing frame 102, and a seed suction port 103-1 is opened on the turntable 103.

[0035] The air hood 104 is connected to the air suction device, and the storage box 101 is connected to the turntable 103 and the air hood 104. When the turntable 103 is rotating, the suction force generated by the air suction device will act on the seeds through the seed suction port 103-1 and adsorb the seeds on one side of the turntable 103. When the turntable 103 is rotating, it can drive the seeds to move, thereby transporting the seeds and completing the sowing of the seeds.

[0036] The auxiliary component 200 is disposed on the rotating disk 103, and includes a sleeve 201 and a pusher 202. The sleeve 201 is fixed in the seed suction port 103-1. The sleeve 201 is conical and has an air hole 201-1.

[0037] The number of auxiliary components 200 corresponds to the seed suction port 103-1. The thick end of the sleeve 201 is fixed in the seed suction port 103-1. The diameter of the seed suction port 103-1 is relatively large. When adsorbing larger seeds, the force area of ​​the seeds is larger, which can improve the stability of adsorbing larger seeds. When the seeds are small, they will enter the sleeve 201 through the seed suction port 103-1 and move toward the thin end in the sleeve 201. When the seeds move to the position of the same size as the seeds in the sleeve 201, they can be stuck in the sleeve 201, thereby providing stable fixation for the seeds and avoiding the seeds from being blocked in the seed suction port 103-1.

[0038] The air holes 201 - 1 can increase the suction force generated by the sleeve 201 to prevent seeds from entering the interior of the sleeve 201 and clogging the end of the sleeve 201, thereby reducing the suction force on the seeds.

[0039] The pushing member 202 includes a push plate 202a, which is located on one side of the sleeve 201. A support frame 202b is provided on one side of the sleeve 201. A movable column 202c is fixed to one side of the push plate 202a. A rotating sleeve 202d is rotatably connected to one side of the support frame 202b through a bearing. A fixed shaft 202e is fixed in the rotating sleeve 202d. A spiral groove 202c-1 is provided on the movable column 202c. The fixed shaft 202e slides in the spiral groove 202c-1. A gear 202f is fixed to the outside of the rotating sleeve 202d. A rack 202g is fixed to the inside of the air hood 104 through a connecting rod.

[0040] The support frame 202b is U-shaped, and the rack 202g is arc-shaped and coaxial with the turntable 103. When the turntable 103 drives the seeds to move to the position of the feeding tube 105, the gear 202f will mesh with the rack 202g. At this time, the gear 202f will drive the rotating sleeve 202d to rotate. When the rotating sleeve 202d rotates, it will drive the fixed shaft 202e to slide in the spiral groove 202c-1. The cooperation between the two drives the movable column 202c to move, and the movable column 202c drives the push plate 202a to move. When the push plate 202 When a moves, it will push the seeds in the sleeve 201 to move and push the seeds to a position flush with one side of the turntable 103, and the push plate 202a is flush with the turntable 103. When the turntable 103 drives the seeds to contact the mouth of the feed pipe 105, the gear 202f will separate from the rack 202g. At this time, the push plate 202a will stop moving. At the same time, the seeds will fall into the feed pipe 105 and complete the sowing of the seeds. The setting of the push plate 202a can avoid the seeds inside the sleeve 201 from being blocked.

[0041] Example 2

[0042] Reference Figure 1-Figure 10, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, a support block 203 is fixed to one side of the sleeve 201, and a support shaft 204 is fixed to the support frame 202b. The support shaft 204 is rotatably connected to the support block 203 through a bearing.

[0044] One side of the support frame 202b is connected to the sleeve 201 through the support block 203 and the support shaft 204, and the support frame 202b can be rotated to one side.

[0045] Specifically, a torsion spring 205 is fixed to one side of the support block 203, and the other end of the torsion spring 205 is fixed to the support shaft 204. A push rod 206 is fixed to the inner wall of the air hood 104, and the push rod 206 cooperates with the movable column 202c.

[0046] By setting the torsion spring 205, the support shaft 204 and the support frame 202b are supported and positioned, so that the support frame 202b is tightly fitted with one side of the sleeve 201 to prevent the support frame 202b from loosening. When the turntable 103 rotates, it drives the movable column 202c to contact the push rod 206. As the turntable 103 continues to rotate, the push rod 206 will limit the movement of the movable column 202c. At this time, the support frame 202b will drive the push plate 202a to rotate to one side and separate the push plate 202a from the end of the sleeve 201. At this time, if there are seeds of unqualified quality inside the sleeve 201 because they are too small, when the push plate 202a is separated from the end of the sleeve 201, the seeds will move out of the sleeve 201 without any obstruction.

[0047] The push rod 206 is located below one side of the turntable 103, and when the movable column 202c contacts the push rod 206, the seed suction port 103-1 can also suck and fix the seeds inside the storage box 101, so that after the unqualified seeds inside the sleeve 201 are discharged, the seed suction port 103-1 can also suck other seeds, thereby avoiding missed seeds during sowing.

[0048] As the turntable 103 continues to rotate, when the movable column 202c separates from the push plate 202a, the torsion spring 205 can drive the support frame 202b to rotate to the initial position, and the push plate 202a can contact the end of the sleeve 201 again, thereby pushing the seeds inside the sleeve 201 to move.

[0049] Specifically, a fixed plate 202c-3 is fixed to one end of the movable column 202c, and a spring 202c-2 is sleeved on the outer side of the movable column 202c. One end of the spring 202c-2 is fixed to the fixed plate 202c-3, and the other end is in contact with the rotating sleeve 202d.

[0050] When the movable column 202c moves, it will drive the fixed plate 202c-3 to squeeze the spring 202c-2. When the gear 202f is separated from the rack 202g and the seeds enter the feed tube 105, the spring 202c-2 can apply thrust to the fixed plate 202c-3, and the fixed plate 202c-3 can drive the movable column 202c and the push plate 202a to reset.

[0051] Specifically, a collecting box 207 is fixed to one side of the push rod 206, and a blanking plate 208 is fixed to one side of the collecting box 207. The blanking plate 208 is inclined, and one side of the collecting box 207 is hollow.

[0052] The unqualified seeds discharged from the inside of the sleeve 201 will fall on the top of the drop plate 208, and the seeds will flow into the collection box 207 through the drop plate 208, so that the defective seeds can be collected by the collection box 207 to prevent the defective seeds from clogging the inside of the air suction device.

[0053] Specifically, a positioning column 209 is fixed to one side of the push plate 202 a , a positioning plate 210 is fixed to the bottom of the support frame 202 b , and the positioning column 209 is movably connected to the positioning plate 210 .

[0054] The positioning column 209 cooperates with the positioning plate 210 to limit the push plate 202a to prevent the push plate 202a from rotating when moving.

[0055] Example 3

[0056] Reference Figures 1 to 4 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0057] Specifically, there are multiple seed suction ports 103 - 1 and multiple sleeves 201 , which are evenly distributed on the rotating disk 103 in a ring shape.

[0058] By providing a plurality of seed suction ports 103 - 1 and sleeves 201 , a plurality of seeds can be sucked and sown at the same time.

[0059] Specifically, a feeding pipe 105 is provided on one side of the fixing frame 102 , the feeding pipe 105 cooperates with the rotating disk 103 , and a supporting wheel 106 is provided on one side of the fixing frame 102 .

[0060] The seeds sucked by the turntable 103 will be transported to the feed pipe 105, and the seeds will be transported to the soil through the feed pipe 105, and then the seeds will be buried through the support wheel 106. This is the existing technology, and this solution will not be elaborated, and those skilled in the art can clearly understand the working principle.

[0061] Specifically, the sowing assembly 100 further includes a mounting frame 107 , which is connected to the fixing frame 102 , and a fertilizer bin 108 is disposed on the top of the fixing frame 102 .

[0062] The mounting frame 107 is used to support and fix the fixed frame 102, and the fixed frame 102 can fine-tune the installation position on the mounting frame 107, so that the sowing spacing can be adjusted. This is the prior art and will not be elaborated in this scheme. Those skilled in the art can clearly understand the working principle. The fertilizer bin 108 is used to store fertilizers.

[0063] Specifically, a scraper 109 is provided on one side of the fixing frame 102 .

[0064] The blade 109 is used to dig the soil so that seeds can be planted under the soil.

[0065] During use, as the turntable 103 rotates, when the seed suction port 103-1 contacts the seeds, the air suction device will cooperate to make the seed suction port 103-1 absorb the seeds and make the seeds close to the turntable 103, so that the turntable 103 can drive the seeds to move. Moreover, since the diameter of the seed suction port 103-1 is large, when adsorbing larger seeds, the force area for adsorbing the seeds is large, thereby improving the stability of adsorbing larger seeds. When the seeds are small, they will enter the sleeve 201 through the seed suction port 103-1 and move toward the thin end in the sleeve 201. When the seeds move to the position of the same size as the seeds in the sleeve 201, they can be stuck in the sleeve 201, thereby providing stable fixation for the seeds and avoiding the seeds from being blocked in the seed suction port 103-1.

[0066] When the turntable 103 is rotating, it drives the movable column 202c to contact the push rod 206. As the turntable 103 continues to rotate, the push rod 206 will limit the movement of the movable column 202c. At this time, the support frame 202b will drive the push plate 202a to rotate to one side and separate the push plate 202a from the end of the sleeve 201. At this time, if there are seeds of unqualified quality inside the sleeve 201 because they are too small, when the push plate 202a is separated from the end of the sleeve 201, the seeds will move out of the sleeve 201 without any obstruction.

[0067] At this time, the seed suction port 103-1 will again suck and fix the seeds inside the storage box 101, so that after the unqualified seeds inside the sleeve 201 are discharged, the seed suction port 103-1 can still suck other seeds, thereby avoiding the situation of missing seeds during sowing.

[0068] When the turntable 103 drives the seeds to move to the position of the feeding tube 105, the gear 202f will mesh with the rack 202g, and the gear 202f will drive the rotating sleeve 202d to rotate. When the rotating sleeve 202d rotates, it will drive the fixed shaft 202e to slide in the spiral groove 202c-1, and the movable column 202c will move through the cooperation of the two, and the movable column 202c will drive the push plate 202a to move. When the push plate 202a moves, it will push the inside of the sleeve 201 The seeds move and are pushed to a position flush with one side of the turntable 103, and the push plate 202a is flush with the turntable 103. When the turntable 103 drives the seeds to contact the mouth of the feed tube 105, the gear 202f will separate from the rack 202g. At this time, the push plate 202a will stop moving. At the same time, the seeds will fall into the feed tube 105 and complete the sowing of the seeds. The setting of the push plate 202a can avoid the seeds inside the sleeve 201 from being blocked.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
