Embodiment 1

[0028] Embodiment 1: as Figure 1-7Shown: a plug seedling replanting device, including a casing 1, a button 2, a pressing piece 3, an air bag 4, a spring 5, a split piece 6, a pressing rod 7, a hose 8, a seeding tray 10, a sealing piece 11, Seed box 12; the inner top of the shell 1 is provided with a pressing piece 3, the upper end of the pressing piece 3 is connected with the button 2, the lower end of the pressing piece 3 is connected with the air bag 4, the spring 5 is set outside the air bag 4, and the air bag 4 is fixed on the split piece 6 above; the lower end of the casing 1 is provided with a seeding tray 10, the lower end of the seeding tray 10 is connected with a seed box 12, and the seed box 12 is provided with a sealing sheet 11; one end of the hose 8 is connected with the split sheet 6, and the other end is connected with the The seeding disc 10 is connected; one end of the pressing rod 7 is connected with the pressing piece 3, and the other end is connected with ...

Embodiment 2

[0031] Embodiment 2: the remainder of the present embodiment is the same as in Embodiment 1, wherein when sowing rape seeds, the average seed diameter is 1.5mm, circular; the seeding disc 10 is a fan-shaped plate with an angle of 110 °, and the cylindrical surface 16 is clamped with the straight line edge Angle is that the position of 45 ° has the seed suction port 22, and the seed suction port 22 diameter is 1mm.

Embodiment 3

[0032] Embodiment 3: the remainder of the present embodiment is identical with embodiment 1, and when wherein sowing notoginseng seed, seed diameter is 3.5mm on average, circular, and the fan-shaped plate angle of seeding disc 10 is 135 °, and on cylindrical surface 16 and straight line edge The included angle is that the position of 70° has a seed suction port 22, and the diameter of the seed suction port 22 is 2.5mm.

[0033] During work, seeds are added into the seed case 12 from the seed port 24 on the seed case 12 respectively. In the initial state, the air bag 4 is in a natural state, and the seed tray 10 is in a natural position. At this time, the seed suction port 22 on the seed tray 10 is outside the seed box 12 and above the seed port 14 . When starting to work, press the button 2, the button 2 squeezes the airbag 4 through the pressing piece 3, and the air in the airbag 4 is discharged from the seed suction port 22 on the seed tray 10 along the hose; the pressing ro...

Abstract

The invention relates to a plug seedling replanting device and belongs to the field of agricultural machinery. The plug seedling replanting device comprises a shell, a button, a pressing piece, an airbag, a spring, a dividing piece, a pressing rod, a hose, a seed discharging plate, a sealing piece and a seed box, the pressing piece is arranged at the top end inside the shell, the upper end of the pressing piece is connected with the button while the lower end of the pressing piece is connected with the airbag, and the spring sleeves outside the airbag which is fixed on the dividing piece; the seed discharging plate is arranged at the lower end of the shell, the lower end of the seed discharging plate is connected with the seed box, the sealing piece is arranged on the seed box, one end of the hose is connected with the dividing piece while the other end of the same is connected with the seed discharging plate, and one end of the pressing rod is connected with the pressing piece while the other end of the same penetrates the dividing piece to be connected with the seed discharging plate. The plug seedling replanting device is small in size and simple to operate; a negative pressure adsorption-type principle is adopted, so that seedling accuracy is high; by changing size of seed absorbing holes, so that the plug seedling replanting device is suitable for replanting of leaking seeds different in size and can be used for seeding operation during large-scale production, labor intensity of seed distributing is lowered, working efficiency is improved.

Description

technical field [0001] The invention relates to a device for replanting seedlings in plug trays, which belongs to the field of agricultural machinery. Background technique [0002] When raising seedlings in plug trays, you can use machinery to quickly sow seeds, but any machinery will have seed leakage. If seed leakage occurs, the seedlings will not emerge uniformly, which will affect the economic value of the seedlings. At present, my country's seedling enterprises usually use artificial replanting when they find missing seeds. When raising seedlings, many seeds are very small, with a diameter of only about 1-3mm. When replanting manually, it is laborious to separate a single seed. If there is a replanting device that is suitable for holding in the hand, workers can easily Carry out replanting operations, thereby greatly improving work efficiency. [0003] Existing hole tray seedling raising and sowing machines are almost all sowing machines that can sow whole trays, and ...
