Description

Technical Field

[0001] This application relates to the field of tobacco planting technology, specifically to a rotary seedling picking device for a tobacco transplanter. Background Technology

[0002] A tobacco transplanter is an agricultural machine used in tobacco cultivation, primarily for transplanting cultivated tobacco seedlings from seedling trays or seedbeds to the field. Its application can significantly improve transplanting efficiency, reduce labor costs, and ensure uniformity and survival rate of transplanted seedlings. It includes at least a seedling tray that can automatically lower the seedlings; however, the flipping process of the seedling tray's cover in existing technologies suffers from jamming and requires design improvement. Utility Model Content

[0003] A rotary seedling-retrieving device for a tobacco transplanter, comprising:

[0004] A mounting bracket is provided for connecting the frame of the tobacco transplanter, and the mounting bracket is provided with a bearing for accommodating the rotation of the central axis.

[0005] A rotating assembly includes a rotating disk, a rotating central shaft disposed on the lower end face of the rotating disk, and a sprocket disposed at the lower end of the rotating central shaft. The rotating disk has mounting holes evenly distributed around its circumference, and the mounting holes are provided with at least one.

[0006] A limiting ring is provided on the mounting bracket and located below the rotating assembly. The limiting ring includes an arc segment disposed in the horizontal plane and coaxial with the rotation axis, a guide segment disposed at the end of the arc segment and inclined downward, and a mounting base disposed below the arc segment and connected to the mounting bracket. The central angle of the arc segment is not less than 0°.

[0007] The seedling tube is inserted into the mounting holes one by one. The seedling tube includes a tube body and a flip cover hinged to the bottom of the tube body.

[0008] The shape of the flip cover is formed by offsetting the lower end of the cylinder outward by a distance of mm, and the lower end of the flip cover abuts against the upper end of the arc segment.

[0009] The cylindrical body includes a tapered section that gradually narrows from top to bottom and a straight section located below the tapered section.

[0010] The flip-top cover has a weight-adding block at its lower end.

[0011] Each seedling tube is also equipped with a torsion device to drive the flip cover to flip downward relative to the tube body. The torsion device includes a pair of hinged lugs on the side of the tube body, a side base on the side of the flip cover, a hinged central shaft on the side base and inserted into the hinged lugs, and a torsion spring on the hinged central shaft.

[0012] Beneficial effects:

[0013] The rotary seedling picking device for a tobacco transplanter described in this case can use a torsion spring to assist the flipping cover in flipping down relative to the cylinder, making the flipping process quick and smooth.

[0014] The rotary seedling taking device for a tobacco transplanter described in this case provides a quick connection method between the flip cover and the cylinder, which can be quickly disassembled and replaced when the flip cover is damaged.

[0015] The rotary seedling taking device for a tobacco transplanter described in this case can also adjust the torque of the torsion spring to adjust the effect of the flipping cover flipping down. Attached Figure Description

[0029] A rotary seedling-retrieving device for a tobacco transplanter, comprising:

[0030] Mounting bracket 1 is used to connect the frame of the tobacco transplanter;

[0031] The rotating assembly 2 includes a rotating disk 21, a rotating central shaft 22 disposed on the lower end face of the rotating disk 21, and a sprocket 23 disposed on the lower end of the rotating central shaft 22. The rotating disk 21 is provided with mounting holes 24 evenly distributed around its circumference.

[0032] The limiting ring 3 is set on the mounting bracket 1 below the rotating assembly 2. The limiting ring 3 includes an arc segment 31 set in the horizontal plane and coaxial with the rotating central axis 22, a guide segment 32 set at the end of the arc segment 31 and inclined downward, and a mounting base 33 set below the arc segment 31 and connected to the mounting bracket 1.

[0033] The seedling tube 4 is inserted into the mounting holes 24 one by one. The seedling tube 4 includes a tube body 41 and a flip cover 42 hinged to the bottom of the tube body 41.

[0034] The shape of the flip cover 42 is formed by offsetting the lower end of the cylinder 41 outward by 5mm, and the lower end of the flip cover 42 abuts against the upper end of the arc segment 31.

[0035] Further:

[0036] The mounting bracket 1 is equipped with a bearing that accommodates the rotation of the central shaft 22.

[0037] Further:

[0038] The mounting socket 24 is provided with at least 6 sockets.

[0039] Further:

[0040] The central angle of the arc segment 31 is not less than 250°.

[0041] Further:

[0042] The cylinder 41 includes a tapered section that gradually narrows from top to bottom and a straight section located below the tapered section.

[0043] Further:

[0044] The flip cover 42 has a weight-adding block at its lower end.

[0045] Further:

[0046] Each seedling tube 4 is also equipped with a torsion device 5, which drives the flip cover 42 to flip downward relative to the tube body 41. The torsion device 5 includes a pair of hinged lugs 51 on the side of the tube body 41, a side base 52 on the side of the flip cover 42, a hinged central shaft 53 on the side base 52 and inserted into the hinged lugs 51, and a torsion spring 54 on the hinged central shaft 53.

[0047] It should be noted that the insertion hole provided on the inner side of the hinge lug 51 is a blind hole.

[0048] Although the flip cover 42 of the seedling tube 4 can flip downwards due to gravity, the flipping action is slow when the rotating assembly 2 rotates rapidly. The torsion device 5 in this case can flip downwards more quickly through the torsion of the torsion spring 54.

[0049] This invention also provides a solution that allows for quick connection between the flip-top cover 42 and the cylinder 41:

[0050] The left end of the torsion spring 54 is inserted into the hinge lug 51 on the left side and bent to prevent it from coming out;

[0051] Press the limiting plug 65 and telescopic contact 64 to the right to overcome the damping of the compression spring 63 and retract them. After they are aligned with the blind hole of the hinge lug 51, they pop out. Note that during the pop-out process, the telescopic contact 64 should be able to pass through the torsion spring 54. After popping out, insert the right side of the torsion spring 54 into the torsion spring slot 66 to fix the torsion spring 54.

[0052] Furthermore, the torque of the torsion spring 54 can be adjusted by twisting the right side of the torsion spring 54 to change its number of turns and then inserting it back into the torsion spring slot 66.
