Drill seeding machine capable of adjusting seeding amount

Abstract

The invention discloses a drill seeding machine capable of adjusting a seeding amount. According to the drill seeding machine disclosed by the invention, a speed detecting and analyzing device is arranged on the drill seeding machine, an instruction is issued by the speed detecting and analyzing device to a seeding and fertilizing device to control a seeding and fertilizing amount, so that accurate cooperation of a fertilizing and seeding speed and a walking speed of the whole machine in the field of drill seeding machines is realized, and seeds and fertilizers are prevented from falling too fast or too slow; a seeding pipe and a fertilizing pipe are arranged as a spiral shape, and compared with a conventional straight pipe, the spiral pipe can slow down a falling speed of a material and prevent the seeds and the fertilizers from falling too fast to cause accumulation in ditches; and a rotary drum type seeding device uses air sucking and air blowing for seeding, and a specific seed-seeding amount within a period of time can be precisely controlled through control of a rotation speed of a rotary drum.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, in particular to a drill seeder capable of adjusting the seeding rate. Background technique [0002] With the increase of the population in our country, the decline of the cultivated land, and the reduction of the agricultural population, the existing sowing and fertilization technology has been transformed from manpower to full mechanical sowing and fertilization. Some seeders only set up a control device in the seeding box, and use the seeding speed in the seeding box to control the sowing amount, but this control method only takes into account the seeding speed of the seed itself, and does not take into account the forward speed of the seeder. The influence of speed on the amount of seeding, with the improvement of the degree of refinement of crops, the disadvantages of this kind of seeding machine are more and more reflected, which is reflected in the fact that due to the hum...

[0002] With the increase of the population in our country, the decline of the cultivated land, and the reduction of the agricultural population, the existing sowing and fertilization technology has been transformed from manpower to full mechanical sowing and fertilization. Some seeders only set up a control device in the seeding box, and use the seeding speed in the seeding box to control the sowing amount, but this control method only takes into account the seeding speed of the seed itself, and does not take into account the forward speed of the seeder. The influence of speed on the amount of seeding, with the improvement of the degree of refinement of crops, the disadvantages of this kind of seeding machine are more and more reflected, which is reflected in the fact that due to the human-driven machine, it will inevitably lead to uneven speed of the seeding machine, but a single seeding The chance of planting seeds with uneven amount and speed will lead to uneven seeding amount each time, and a lot of waste of seeds

[0003] In recent years, online real-time control of sowing and fertilization tools based on speed sensing technology has been actively carried out at home and abroad, but due to technical difficulties and other reasons, it has not been used on a large scale, and there are various technologies in the research of these existing technologies. Problem; For example, the patent No. ZL201621117717.5 applied by Xinjiang Tianxiang Precision Agricultural Equipment Co., Ltd., which is named as a precision seeding system based on Beidou satellites, discloses the following content: "The electronic control unit obtains the walking speed of the planter from the speed sensor, and also passes The flow detection sensor at the bell mouth can obtain the flow of sowing, and process the speed and flow to obtain the real-time sowing situation of the seeder, and then adjust the valve or speed of the bell mouth to accurately sow.” Patent applied by Nanjing Agricultural University The number is ZL201710078726.0, and the name is a real-time variable fertilizer spreader based on crop growth information. ; It can be seen that at present, the technology used to adjust the sowing speed by the walking speed of the whole machine is to change the seeding rate by changing the size of the seed hole in the seed box, but because the seed box is full of seeds, no matter how the seed box hole is controlled Opening and closing can only control the seed discharge within a rough range, and cannot accurately calculate the amount of seed discharge within a period of time for control. At present, in the field of seed drills, there is no information about precise operation according to the walking speed of the whole machine. Current technology for calculating and controlling seed discharge
