Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a single seedling delivery device for a plug seedling transplanter. Background Technology

[0002] With the rapid development of agriculture in my country, seedling trays are now widely used for raising seedlings, especially for vegetables and other crops. This has significantly improved the replanting rate and survival rate of vegetable seedlings, leading to the rapid development of automatic tray seedling transplanters and greatly increasing the planting efficiency of vegetable tray seedlings. Current automatic transplanters require seedling trays to be placed sequentially into a delivery device, which then transports the seedlings from the trays to a fixed position for the retrieval device. Because the seedling trays are exposed to sunlight for extended periods, they are relatively fragile and difficult to position precisely, greatly increasing the difficulty of accurate positioning by the delivery device. Some existing transplanter delivery devices suffer from complex structures and inaccurate delivery positions, significantly impacting the transplanting efficiency of vegetable seedlings and hindering the widespread application of automatic tray seedling transplanters. Utility Model Content

[0003] The purpose of this invention is to solve the problem of inaccurate positioning of seedling trays and to provide a simple and accurate single-seedling delivery device for a plug seedling transplanter.

[0004] This utility model provides the following technical solution: a single seedling delivery device for a plug seedling transplanter, comprising two base plates, a horizontal moving component, a vertical moving component, and a seedling tray limiting component. The horizontal moving component is installed on the two base plates, the vertical moving component is movably connected to the horizontal moving component via a linear bearing and a lead screw nut, and the seedling tray limiting component is installed on the vertical moving component.

[0005] Furthermore, the lateral movement assembly includes four guide shaft supports, which are respectively fixed to the two base plates by bolts. Two optical axes are fixed by guide shaft supports in relative positions for guiding the lateral movement of the longitudinal movement assembly. A lead screw support is fixed to the base plate on the left by bolts. A lead screw fixing seat and a stepper motor fixing seat are fixed to the base plate on the right by bolts. The lead screw support and the lead screw fixing seat are connected to the lead screw. A stepper motor is fixed to the stepper motor fixing seat by bolts and connected to the lead screw by a mortise coupling to provide power for the lateral movement of the longitudinal movement mechanism. Two sensor fixing seats are respectively installed on the two base plates. The sensor fixing seats are equipped with a straight handle limit switch and a contact limit switch. The straight handle limit switch is used to limit the position of the longitudinal movement mechanism, and the contact limit switch is used for power-off protection when the longitudinal movement mechanism is over-displaced.

[0006] Furthermore, the longitudinal movement assembly includes a left side plate and a right side plate. A lead screw nut and two linear bearings are respectively fixed to the left and right side plates. The longitudinal movement assembly is connected to the optical shaft via the linear bearings and to the lead screw via the lead screw nut, driving the longitudinal movement assembly to move laterally. Two bearing seats are respectively installed on the left and right side plates. The four bearing seats respectively fix sprocket shaft one and sprocket shaft two. Sprocket shaft one and sprocket shaft two are symmetrically connected to sprockets at both ends via keys and are driven by a chain. The chain is equidistantly mounted with seedling tray longitudinal movement push rod fixing seats, which fix the seedling tray longitudinal movement push rod to drive the seedling tray longitudinally. Tensioner mounting shafts are respectively installed on the left and right side plates, connecting to tensioners to ensure the chain is in a taut state. A stepper motor mounting seat two is installed on the right side plate to fix the stepper motor two. The stepper motor two is connected to sprocket shaft one via a double-clutch coupling two, providing power to the longitudinal movement mechanism.

[0007] Furthermore, the seedling tray limiting component includes two seedling tray longitudinal positioning rod mounting shafts, which are mounted on the left and right side plates of the longitudinal movement component. The two seedling tray longitudinal positioning rod mounting shafts are connected to seedling tray longitudinal positioning rods to achieve longitudinal movement and positioning of the seedling tray. The left and right side plates of the longitudinal movement component are equipped with a longitudinal seedling conveying edge positioning plate one and a longitudinal seedling conveying edge positioning plate two. The longitudinal seedling conveying edge positioning plate one is used for left and right movement and positioning of the seedling tray, and the longitudinal seedling conveying edge positioning plate two is used for fixing the seedling tray when taking seedlings. The left and right side plates of the longitudinal movement component are also equipped with mounting plates, and the mounting plates are fixed with positioning rod one and positioning rod two, so as to ensure that the seedling tray does not move when other mechanisms take seedlings while realizing the retrieval of the seedling tray.

[0008] Furthermore, by adjusting the spacing of the longitudinal movement push rod fixing seat of the seedling tray on the chain, the spacing of the longitudinal movement push rod of the seedling tray can be adjusted, thereby achieving the positioning of seedling trays of different specifications.

[0009] Furthermore, the two seedling tray longitudinal positioning rod mounting shafts are installed in the strip-shaped holes of the left and right side plates of the longitudinal moving assembly. The positioning of seedling trays of different specifications can be achieved by adjusting the position of the seedling tray longitudinal positioning rod mounting shaft and the position of the seedling tray longitudinal positioning rod on the seedling tray longitudinal positioning rod mounting shaft.

[0010] Furthermore, the two tensioning wheel mounting shafts are installed in the strip-shaped holes of the left and right side plates of the longitudinal moving assembly, and the chain is tensioned by adjusting the position of the tensioning wheel mounting shafts.

Tensioner mounting shafts 3-9 are installed on the left side plate 3-10 and the right side plate 3-13 respectively, connecting to tensioner 3-8 to ensure chain 3-5 is under tension.

[0027] The working principle of this device is as follows: During operation, the seedling tray 5 containing seedlings is placed on the longitudinal positioning rod 3-3 of the longitudinal moving component 3. When the device starts, the control system controls stepper motor 2-8 to rotate, causing the side plate 3-13 of the longitudinal moving component to contact the straight handle limit switch 2-3 installed on the base plate 1. The control system then controls stepper motor 3-16 to rotate, moving the longitudinal moving push rod 3-3 of the seedling tray in the longitudinal moving component 3. Adjustment is made to place the seedling to be grasped in the designated position, achieving a reset operation. For lateral seedling feeding, the control system controls stepper motor 2-8 to rotate through a certain angle, causing the lead screw 2-5 to move the longitudinal moving component 3 one hole distance, achieving lateral seedling feeding. For longitudinal seedling feeding, the control system controls stepper motor 3-16 to rotate through a certain angle, causing the chain 3-5 to move one hole distance, which in turn moves the longitudinal moving push rod 3-3 of the seedling tray one hole distance, ultimately moving the seedling tray 5 one hole distance, achieving longitudinal seedling feeding.

Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
