Problems solved by technology

However, in practical applications, due to the influence of seedling agronomy, the growth and development of plug seedlings are inconsistent. If the seedlings are topped by a fixed mechanical method, the self-adaptive ability of the top seedling mechanism is not enough, and it is easy to break the pot of plug seedlings.

Embodiment approach

[0037] figure 1 Shown is an embodiment of the device for releasing the plug seedlings transplanted by pneumatic power, the device for removing the plug seedlings by pneumatic power includes a pneumatic pot top device, a plug limiting device, a horizontal push Block bowl device and control system 17.

[0038] figure 2Shown is a schematic structural diagram of the pneumatic pot topping device, including a motor 1 , a linear module 2 , a slider 3 , a lifting mechanism 4 , a manifold 5 and an air nozzle 6 . The motor 1 is connected to the power input shaft of the linear module 2, the linear module 2 is flat and fixedly installed on the lower part of the frame 7, and the slider 3 is fixedly connected to the moving platform of the linear module 2; The base body of the lifting mechanism 4 is vertically and fixedly installed on the slider 3, and the manifold 5 is fixed and straight on the movable rod of the lifting mechanism 4; the gas nozzles 6 are arranged in rows and facing the ...

Embodiment 128

[0049] The present invention also provides a method for loosening the pot seedlings transplanted according to the pneumatic jacking pot loosening device, Figure 5 ~ Figure 8 Shown is a schematic diagram of the loosening effect of plug seedlings transplanted by air force top bowl; this embodiment takes the transplanting of 128-hole cucumber plug seedlings as an example, a method for the plug seedlings transplanted by air power top pot loosening, comprising the following steps:

[0050] S1. According to the mechanical requirements of the cucumber plug seedlings sticking to the 6 holes of the plug holes, the adhesion force F of the cucumber plug seedlings in 128 holes is obtained through the test of the force measuring system, which is 2.34N. 8mm, 128 holes cucumber tray seedling pot body compressive failure strength σ is 0.66MPa, so it is determined that the airflow pressure P used for the pneumatic top bowl in the air nozzle 6 aimed at the drain at the bottom of the tray 7 shou...

Abstract

The invention belongs to the field of agricultural machinery, and discloses a pneumatic pot jacking releasing device and a method for transplanting potted seedlings. The pneumatic pot jacking releasing device comprises a pneumatic pot jacking device, a tray limiting device, a pot flat pushing and blocking device and a control system. The control system is electrically connected with a flat pushing mechanism of the pot flat pushing and blocking device and a lifting mechanism and a motor of the pneumatic pot jacking device. The flat pushing mechanism can be driven by the control system to drive a base plate according to starting signals, so that pot blocking strips can be parallelly transversely erected above pots for the integral rows of potted seedlings, and the potted seedlings which are jacked and blown by airflow pressures can be stopped from being released from cells; the lifting mechanism can be driven by the control system to drive a flow concentration plate according to working signals, so that air nozzles can be in close contact with drain outlets of holes of a tray, the pots can be jacked and blown by the airflow pressures which overcome adhesion force of the holes of the tray, and the purpose of releasing the pots from adhesion effects can be achieved, and manual easy seedling pulling or mechanical reliably seedling gripping can be assisted. The pneumatic pot jacking releasing device and the method have the advantages that the pneumatic pot jacking releasing device is simple in structure, the seedlings and the pots can be effectively prevented from being damaged when the seedlings are fetched, and the pneumatic pot jacking releasing device and the method can be used for transplanting the potted seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery research, and in particular relates to a device and method for transplanting plug seedlings with pneumatic jacking pots. Background technique [0002] In recent years, with the structural shortage of agricultural labor force and the development of agricultural modernization technology, research on plug seedling transplanting machines has attracted much attention, and various types of transplanting machines have been developed to replace manual operations. Transplanting plug seedlings mechanically can effectively reduce labor intensity, improve work efficiency, and ensure the quality of transplanting seedlings. [0003] The existing application number is 200820100210.8, and the plug seedling transplanting machine is divided into semi-automatic transplanting machine, and application number is 201520310260.9 automatic transplanting machine. The semi-automatic transplanting machine uses manual o...
