[0032] The lower end of the seed suction needle 13 is used for adsorbing seeds, and the lower end opening thereof cannot be larger than the size of the adsorbed seeds. During the adsorption and placement of the seeds, the lower end opening of the seed suction needle 13 continuously adsorbs the seeds by generating adsorption force through pressure relief of the air bag 12. Since the seeds cannot enter the seed suction needle 13, the seeds are adsorbed at the end of the seed suction needle 13, thereby avoiding adsorption of excess seeds. In this way, the control of the number of seeds adsorbed and placed is realized, and the precision of seeding is ensured.

[0033] The mounting bracket 11 includes a side plate 112, and the first ends of the plurality of side plates 112 are pivotally connected along the vertical direction. The pivot axis of the side plate 112 has an included angle with the normal line of the side plate 112, and the air bag 12 is installed on the same side of the side plate 112, so that the side plates 112 of two adjacent seeding units 1 are adapted to press the air bag 12 located between the two side plates 112.

[0034] Therefore, the mounting bracket 11 serves as a mounting carrier of the entire seeding device 100, the side plate 112 is used for fixing the air bag 12, the first ends of the side plates 112 of the plurality of mounting brackets 11 are pivotally connected along the vertical direction, that is, the side plates 112 of the plurality of mounting brackets 11 can rotate in the horizontal direction about the axis extending in the vertical direction, so that the mounting bracket 11 can drive the air bag 12 to rotate, that is, the plurality of side plates 112 are pivotally connected, so that the plurality of seeding units 1 can relatively rotate along the vertical direction.

[0035] ​According to the utility model discloses a plurality of seeding units 1, namely two or more, the number of seeding units 1 can be set according to specific circumstances, in some examples, such as Figure 1 The utility model discloses a plurality of seeding units 1, namely two or more, the number of seeding units 1 can be set according to specific circumstances, in some examples, such as Figure 1 The utility model discloses a plurality of seeding units 1, namely two or more, the number of seeding units 1 can be set according to specific circumstances, in some examples, such as

[0036] In some embodiments, the first end of the side plate 112 of the plurality of seeding units 1 is pivotally connected along the vertical direction, and any seeding unit 1 can rotate at any angle along the vertical pivot axis, so that the adjacent seeding units 1 can be in contact by rotating and pressing.

[0037] In some examples, the seeding device 100 further comprises a pivot shaft 2, and the first end of each side plate 112 is provided with a through hole 30 extending along the vertical direction, and the pivot shaft 2 extends into the through holes 30 of the plurality of side plates 112 in sequence, so as to realize the rotary connection of the plurality of side plates 112.

[0038] In some examples, the motion trajectories of the plurality of seeding units 1 coincide. It is ensured that the adjacent seeding units 1 can be in contact by rotating, so that the side plate 112 of any seeding unit 1 can fully contact and press the air bag 12 of the adjacent seeding unit 1, thereby forming effective pressing.

[0039] The utility model discloses a plurality of seeding units 1 pivotally connected, which has the characteristics of simple structure, light weight and convenient maintenance. By operating the seeding device 100, the seeding units 1 are relatively rotated along the vertical pivot axis, the air bag 12 of one side of the seeding unit 1 is pressed to deform and generate negative pressure by the side plate 112 of the other side of the seeding unit 1, the seeds are adsorbed on the seed tray by the seed suction needle 13, and the seeding device 100 is operated again to move the seeding units 1 away from each other, so that the air bag 12 of the pressed seeding unit 1 is released, and the seed suction needle 13 is automatically released from the adsorbed seed when the pressure is released to a certain degree. The utility model discloses a seeding device 100, which is simple and fast to operate, and has high seeding efficiency.

[0040] Some embodiments of the utility model will be described below with reference to Figures 1-4 The utility model discloses a plurality of seeding units 1, namely two or more, the number of seeding units 1 can be set according to specific circumstances, in some examples, such as

[0041] In some embodiments, such as Figure 2 and Figure 4As shown, the mounting bracket 11 also includes a base plate 111. The base plate 111 is connected to and bent at the lower end of the side plate 112, so that the lower end of the airbag 12 is supported on the base plate 111. The side of the airbag 12 closest to the side plate 112 is connected to the side plate 112, and the bottom of the airbag 12 is supported by the base plate 111. In this way, the connection between the airbag 12 and the mounting bracket 11 is firm, and it is not easy for the airbag 12 to be misaligned during the use of the seeding device 100. In particular, the bending direction of the base plates 111 of multiple mounting brackets 11 is the same, and the airbag 12 is placed in the bending direction of the base plate 111, that is, the airbag 12 is installed on the same side of the side plate 112, so that the side plates 112 of two adjacent seeding units 1 are suitable for compressing the airbag 12 located between the two side plates 112. When adjacent seeding units 1 rotate and come into contact vertically, the side plate 112 of any seeding unit 1 can fully contact the air bladder 12 of the other seeding unit 1 without being affected by the bending direction of the bottom plate 111 of the other seeding unit 1, so that the air bladder 12 of the squeezed seeding unit 1 can generate effective deformation and generate negative pressure.

[0042] In some embodiments, the angle between the base plate 111 and the side plate 112 is α, satisfying α > 90°. Thus, when multiple sowing units 1 rotate and contact each other, the base plate 111 of one mounting bracket 11 is prevented from obstructing the rotation of another mounting bracket 11. The compressed air bladder 12 at the sowing unit 1 can generate a larger deformation, allowing the air inside the air bladder 12 to be expelled more thoroughly, creating a larger negative pressure inside, which is beneficial for the seed-absorbing needle 13 to adsorb seeds.

[0043] In some embodiments, such as Figure 4 The mounting bracket 11 shown also includes a reinforcing plate 113, the lower end of which is connected to the base plate 111, and the side of the reinforcing plate 113 is connected to the side plate 112. In some examples, the reinforcing plate 113 may be configured as follows: Figure 4 The triangular shape shown enhances the strength of the reinforcing plate 113 in the bending direction of the base plate 111. In some embodiments, the reinforcing plate 113 is disposed at one end of the base plate 111 and the side plate 112 near the pivot axis and at the other end away from the pivot axis. That is, the side plate 112, the base plate 111, and the reinforcing plate 113 together define a mounting groove for accommodating the airbag 12, in which the airbag 12 is mounted. The reinforcing plate can limit the displacement of the airbag 12 along the length direction of the base plate 111 and the side plate 112.

[0044] In some embodiments, such as Figure 3 and Figure 4As shown, the bottom plate 111 is provided with a plurality of through holes 20, and the air bag 12 is provided with a plurality of seed suction needles 13. The number of the through holes 20 is not less than the number of the seed suction needles 13, so that the bottom plate 111 is provided with the through holes 20 for each seed suction needle 13 to pass through. The seed suction needle 13 extends out of the bottom plate 111 from the through hole 20. The axis of the through hole 20 is in the vertical direction, so that the seed suction needle 13 can always be kept vertical, facilitating the seeding operation.

[0045] In some examples, the diameter of the seed suction needle 13 is 0.06 cm, which is suitable for seeds with a minimum side length greater than or equal to 0.06 cm. The seed suction needle 13 has high inclusiveness for the shape of the seed and can achieve plug seeding for a variety of plant seeds. The number and size of the through holes 20 on the bottom plate 111 can be changed according to actual needs, for example, 6 holes, 7 holes, or 8 holes. The number and size of the seed suction needle 13 can be changed within a corresponding range. In this way, the seeding device 100 can flexibly set and change the specifications of the seeding unit 1 according to different seeding needs, meeting the needs of different types and different specifications of seeding.

[0046] In some embodiments, as shown in Figure 2 and Figure 3 , one side of the air bag 12 of the seeding unit 1 is attached to the side plate 112, and the side of the air bag 12 attached to the side plate 112 is provided with a protruding limiting portion 121. The side plate 112 is provided with a limiting hole 10, and the limiting portion 121 is adapted to be connected into the limiting hole 10. The size of the limiting portion 121 is slightly larger than the size of the limiting hole 10. The limiting portion 121 is inserted into the limiting hole 10 in an interference fit, so that the air bag 12 and the side plate 112 are firmly connected. During the use of the seeding device 100, the air bag 12 does not relatively displace in the radial direction of the limiting hole 10, so that when the side plate 112 of any seeding unit 1 contacts and presses the air bag 12 of the adjacent seeding unit 1, a larger compression amount is generated, forming effective pressing.

[0047] In some embodiments, as shown in Figure 2 and Figure 4 , the air bag 12 and the side plate 112 are connected by the limiting hole 10 and the limiting portion 121, and the seed suction needle 13 is positioned by the through hole 20 of the bottom plate 111. The air bag 12 and the seed suction needle 13 can be taken out of the mounting bracket 11 in the vertical direction. In this way, the air bag 12 and the seed suction needle 13 are convenient to disassemble and replace, which is beneficial to later maintenance. Users can also change the specifications of the seed suction needle 13 according to their own needs to adapt to a variety of specifications of seeds, reducing the use cost of users.

[0048] According to the embodiment of the utility model, the distance between the through hole 20 and the pivot axis of the bottom plate 111 is L1, the distance between the limiting hole 10 and the pivot axis of the side plate 112 is L2, and L1 is not equal to L2. That is, in the length direction of the mounting bracket 11, the through hole 20 and the limiting hole 10 are staggered, and the through hole 20 or the limiting hole 10 is arranged at different positions from the pivot axis to limit the air bag 12. In the length direction of the mounting bracket 11, a position for limiting the air bag 12 is arranged more densely, and the connection strength between the air bag 12 and the mounting bracket 11 is effectively enhanced while ensuring the structural strength of the mounting bracket 11.

[0049] In some embodiments, as shown in Figure 3 and Figure 4 , the seed suction needle 13 is a taper with a larger upper cross-sectional area than a lower cross-sectional area, the through hole 20 is a tapered through hole, and the shape of the through hole 20 matches the shape of the seed suction needle 13. Thus, after the air bag 12 is installed on the mounting bracket 11, the upper end of the seed suction needle 13 can be placed in the tapered groove of the tapered through hole, the tapered through hole can position the seed suction needle 13, and the edge of the tapered through hole can reserve a deformation amount to prevent the seed suction needle 13 from being offset or blocked by the surrounding edge of the through hole 20 when the seeding device 100 is working.

[0050] According to the embodiment of the utility model, in some embodiments, as shown in Figure 1 , the distance between one end of the air bag 12 close to the pivot axis of the side plate 112 and the pivot axis is L3, and L3 is greater than 0. By using the lever principle, the force arm is increased, and the operator of the seeding device 100 can rotate the seeding unit 1 more easily. In addition, L3 greater than 0 can also avoid uneven pressure on the air bag 12 in the length direction of the side plate 112, which can cause uneven suction force on the seed suction needle 13 on the bottom plate 111, and thus cause uneven suction of the seed suction needle 13.

[0051] In some embodiments, as shown in Figure 4 , the mounting bracket 11 further includes an extension plate 114 arranged at one end of the side plate 112 close to the pivot axis. The extension plate 114 increases the distance between one end of the air bag 12 close to the pivot axis and the pivot axis, that is, increases the force arm of the seeding device 100, so that the user of the seeding device 100 can operate more easily.

[0052] In some embodiments, as shown in Figure 4As shown, the mounting bracket 11 further comprises a handle 14 connected to the second end of the side plate 112 and extending away from the first end. The handle 14 serves as a force application point, and an operator of the seeding device 100 manipulates the handle 14 to rotate any seeding unit 1 of the seeding device 100 about the pivot shaft 2 in the vertical direction, and the rotated seeding unit 1 completes the seeding operation by depositing seeds into the hole of the hole plate through the deformation recovery process of the air bag 12. The seeding device 100 is simple in structure, labor-saving in use, and improves the seeding efficiency.

[0053] It should be noted that the mounting bracket 11 is made of metal material, such as aluminum alloy or stainless steel material, to ensure a certain strength; the air bag 12 is made of thin-walled hollow high-elastic material, such as rubber material, to ensure that the air bag 12 can rebound quickly after being compressed.

[0054] In some embodiments, the seeding device 100 further comprises a seed plate arranged below the seeding unit 1, the seed plate having a length and a width greater than those of the seeding unit 1, and being used for accommodating seeds; and a hole plate arranged on the front side or the rear side of the seed plate, the hole plate comprising hole plate specifications corresponding to the specifications of the seeding unit 1, respectively, 72 holes corresponding to 6 holes (6 holes x 12 holes), 98 holes corresponding to 7 holes (7 holes x 14 holes), and 105 holes (7 holes x 15 holes), and 128 holes corresponding to 8 holes (8 holes x 16 holes), and being used for seeding.

[0055] It should be noted that the 72-hole, 98-hole, 105-hole, and 128-hole hole plates used for hole plate seeding in the art are all applicable to the present application, and can be prepared by oneself or purchased commercially, and the specific manufacturers and models are not strictly limited, and can be flexibly selected according to actual needs.

[0056] When using the seeding device 100, the adjacent seeding units 1 are rotated about the pivot shaft 2 by manipulating the handle 14, which can be opposite rotation between the adjacent seeding units 1, or one side of the seeding units 1 remains stationary and the other side of the seeding units 1 rotates alone. When the adjacent seeding units 1 are in contact, the air bag 12 of one side of the seeding units 1 is in contact with the mounting bracket 11 of the other side of the seeding units 1, and the air bag 12 of the extruded side of the seeding units 1 is extruded to discharge the internal air to generate negative pressure; the operator manipulates the handle 14 again to separate the extruded and contacted seeding units 1 from each other, the air bag 12 of the extruded side of the seeding units 1 is depressurized to generate suction force at the seed suction needle 13 to adsorb seeds at the seed plate, and the seeding device 100 is placed above the hole plate, and when the pressure relief reaches a certain degree and the suction force decreases, the seeds fall into the hole.

[0057] The seeding device 100 can be widely applied in the field of agricultural and forestry technology, and the seeding units 1 of different specifications can be selected according to the plug specifications.
