Description

Technical Field

[0001] The invention relates to the technical field of onion seedling transplanting and planting, in particular to an onion seedling supply mechanism, equipment and method for onion seedling transplanting. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Taking the transplanting of green onions in Zhangqiu as an example, the work of green onion transplanting has gradually been replaced by semi-automatic or automatic machinery from the traditional complex manual operation. Among them, the fully automatic transplanter is only used for transplanting seedlings in plug trays, while the applicable machinery for transplanting green onion seedlings from the field after field breeding of green onion seeds is mainly finger clamp type, chain clamp type and duckbill type. Due to the particularity of mechanized transplanting devices and principles, it is difficult to ensure the quality of green onion seedlings during transplanting, especially the green onion transplanters on the market are mostly powered by tractors, and in order to adapt to the wheelbase of the tractor, the transplanters are mostly duplex structures, which are difficult to operate and difficult to ensure the quality of transplanting.

[0004] Most of the transplanters on the market that are suitable for transplanting onion seedlings from the field after field propagation of onion seeds are semi-automatic transplanters. They use manual seedling separation and supply, which is labor-intensive and difficult to ensure the quality of seedling separation and transplanting spacing, resulting in a low transplanting upright rate. In order for the transplanter to be recognized and accepted by users, it is necessary to design a seedling feeding device and an upright planting device on the transplanter.

[0005] Since the current transplanting method is mainly suitable for transplanting small seedlings and requires manual assistance, for transplanting large seedlings, especially green onion transplanting, the green onion seedlings are about 180 mm long and 10 mm in diameter. The green onion seedlings have a certain weight. The traditional small seedling transplanting method requires staff to assist in transplanting the seedlings for a long time, and there is a problem of high work intensity. This is mainly because the seedling supply mechanism in the existing transplanter does not meet the seedling supply requirements of the green onion seedlings.

[0006] Of course, there are also automatic transplanters for green onion seedlings disclosed in the prior art, which are aimed at thin green onion seedlings with a length of less than 10 cm. They require a transfer seedling tray and are not suitable for longer green onion seedlings. In addition, the overall structure is complex; the power mechanism and some mechanisms are spaced far apart, affecting the response accuracy of the overall structure; the flexible disc is used as a planting mechanism, and the squeezing force on the green onion seedlings is relatively large, which easily causes the green onion seedlings to be damaged.

[0053] As introduced in the background technology, the onion seedling transplanting mechanism in the prior art has the problem of complex structure. In order to solve the above technical problem, the present invention proposes a seedling supply mechanism for onion seedling transplanting.

[0054] Embodiment 1

[0055] In a typical embodiment of the present invention, reference is made to Figure 5 and Figure 6 As shown, a seedling supply mechanism for transplanting onion seedlings comprises a support ring 24 and a support component 23. The support ring 24 is hollow so as to be inserted into the support shaft of the onion seedling transplanting equipment. The support component 23 is located in the circumferential direction of the support ring 24. The support component 23 and the support ring are spaced apart at a distance. The onion seedlings 22 are circumferentially sleeved with protective members. A plurality of onion seedlings are closely arranged in a set manner between the support component 23 and the support ring 24. Both sides of the onion seedlings 22 are exposed from the end sides of the support component 23. The exposed length of the onion seedlings 22 from one end of the support component 23 is greater than the exposed length of the onion seedlings from the other end of the support component. An opening can be formed on one side of the support component 23 under the action of an external force. The width of the opening matches the diameter of a single onion seedling 22, and the length of the opening is the same as the thickness of the support component 23.

[0056] Among them, the support ring 24 is a flexible support ring or a flexible part is arranged on the outer annular surface of the support ring. The flexible support ring can be a rubber support ring, and the flexible part can be made of rubber material to avoid damaging the onion seedlings.

[0057] In some examples, the support component 23 is circular, and in some examples, the support component 23 is hexagonal.

After the support component is fixed to the transplanting equipment, the notch is torn open under the action of external force or the notch is cut by a tool to form an opening on the bottom side of the support component. Under the action of gravity, the onion seedlings fall one by one from the opening.

[0058] Specifically, the protective member 25 is a protective ring, which can be a protective paper ring. The protective member can be buried in the soil together with the onion roots during the transplanting process and is degradable. The length of the protective member 25 is the same as the height of the support ring, and the shape of the protective ring is the same as the shape of the support component. The protective ring fits the onion seedlings. When the support component 23 is a hexagon, the protective ring is also a hexagon, so as to ensure the spacing between two adjacent onion seedlings, thereby ensuring the transplanting distance between the green onions during the transplanting process;

[0059] The seedling supply mechanism provided in this embodiment arranges the onion seedlings 22 closely between the support component and the support ring, and the support component can form an opening. In this way, before the opening is formed, the seedling supply mechanism as a whole is convenient for overall movement and installation. After the opening is formed, the onion seedlings 22 are supplied downward from the opening, thereby realizing the supply of longer onion seedlings with larger diameters, and no manual assistance is required for the seedling supply during the movement of the machine.

Fig.10 As shown, a flexible protrusion 32 is provided on the inner surface of the flexible disc 19 near the side of the flexible disc, and the flexible protrusion 32 is provided along the radial direction of the flexible disc. The flexible protrusion 32 has a set height and a set length, and the flexible protrusion is a rubber protrusion. The angle between two adjacent flexible protrusions is less than or equal to 10°;

[0075] It should be noted that the planting mechanism using a flexible disc is an existing technology. A clamping mechanism 27 is set on the outside of the flexible disc. The clamping mechanism 27 can realize the directional transportation of the onion seedlings between the clamping pad and the release point. The clamping mechanism is an existing technology and will not be described in detail.

[0076] The transplanting equipment provided by the present embodiment has a seedling supply mechanism that supplies seedlings to the onion seedling guide mechanism, and the onion seedlings enter the onion seedling guide mechanism, and then are transplanted through the planting mechanism. The overall structure is simple, and there is no complicated seedling supply mechanism. It can realize automated operation without the assistance of personnel, and can achieve the agronomic requirements of onion seedling transplanting by independently walking in the ditch for upright planting, thereby reducing the labor cost of transplanting and improving the uprightness of onion seedling transplanting. Moreover, the overall structure is reasonably arranged, and the various components are cleverly arranged to realize the effective seedling supply and transplanting of onion seedlings, and ensure the effective driving of the various components by the power mechanism.

[0077] Embodiment 3

[0078] This embodiment provides a working method of a seedling supply mechanism for transplanting green onion seedlings, including the following contents:

[0079] Place rack 1 in the furrow;

[0080] The seedling supply mechanism 4 is installed on the mounting plate 3 for support, and an opening is slid out from the bottom side of the support member 23, and the opening of the support member 23 is aligned with the upper side of the onion seedling guide mechanism;

[0081] The transplanting equipment moves along the direction of the ditch in the ditch by the power provided by the engine, and the onion seedlings enter the onion seedling guide mechanism 9 through the opening of the support component 23 under the action of gravity, and the onion seedling guide mechanism 9 sends the onion seedlings to the planting mechanism 6;

[0082] When the flexible disc 19 in the planting mechanism 6 receives the onion seedlings released by the onion seedling guide mechanism 9, the flexible disc will be clamped at the onion seedling contact point under the action of the clamping mechanism 27. When the flexible disc 19 rotates, the clamped onion seedlings will rotate with the disc. When the onion seedlings move to the specified position, the clamping force of the clamping device disappears and the onion seedlings fall upright into the furrow opened by the furrow opener 8. Then the covering wheel 5 completes the covering and pressing of the onion seedlings, completing one onion seedling transplanting operation.

[0083] When all the onion seedlings in the seedling supply mechanism have been supplied, the continuous operation of the seedling supply mechanism is achieved by replacing the new seedling supply mechanism 4.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
