Magnetic suction precision sowing method and its equipment

Abstract

The invention relates to a magnetic suction precision sowing method and device suitable for precision sowing of small grain seeds such as vegetables, flowers and seedlings. The method is to form a magnetic suction type seed picker by a magnetic suction head, an electromagnetic coil, a diamagnetic sleeve, etc., and pass a current to the electromagnetic coil to make the magnetic suction head generate a certain magnetic induction intensity, thereby generating a certain amount of pressure at the lower end of the magnetic suction head. The magnetic field, using the presence or absence of magnetic force, absorbs and broadcasts seeds to achieve precision sowing; adjusting the magnitude of the electromagnetic coil energizing current can obtain different magnetic field forces to achieve precision sowing of seeds of different particle sizes. The device includes a sowing mechanism, a magnetic seed picker, a seed box, a conveying platform, a conveyor belt, a tray, a motor, etc. The sowing mechanism is a parallelogram mechanism, and a magnetic suction type is installed on it according to the hole distance of the tray. Seed taker. The method can realize both on-demand sowing and drill sowing, and the precision sowing rate of single grain is high, the sowing speed is fast, and the seeds are not damaged.

Description

technical field

[0001] The invention relates to a sowing method suitable for precision sowing of small-particle seeds such as vegetables, flowers and seedlings, in particular to a magnetic suction precision sowing method. The invention also relates to a precision sowing device for plug seedlings designed by using the method. Background technique

[0002] In the early 1970s, the United States first introduced the industrial plug seedling technology. Because this technology has the characteristics of high speed, high quality and high yield, it has been rapidly promoted in other agricultural economically developed countries such as the Netherlands, France, Germany, Japan and other countries. . One of the key technologies to be solved in industrial plug seedling technology is the precision on-demand sowing of seeds. Since most vegetables and flower seeds are small in size, light in weight and irregular in shape, it brings difficulties to the precision sowing of seeds. At presen...

Examples

Embodiment Construction

[0015] Such as figure 1 Shown, form a magnetic suction type seed picker (10) by electromagnetic coil (1), magnetic suction head (2), diamagnetic sleeve pipe (3), magnetic suction head (2) is columnar iron core, gives electromagnetic coil (1) is connected with a certain current to generate a certain magnetic field at the lower end of the magnetic suction head (2). Overcoming the gravity of the seeds, the seeds are sucked up and attached to the lower end of the magnetic suction head (2); when the magnetic suction head (2) moves above the hole of the tray, the current in the electromagnetic coil (1) is cut off, the electromagnetic field disappears, and the magnetic suction There is only weak residual magnetic field left in the head (2), and the residual magnetic field force is not enough to overcome the self gravity of the seed, so the seed (4) will fall, and currents of different sizes are passed to obtain magnetic field forces of different sizes. The material of the magnetic s...
