Problems solved by technology

The air-suction precision seeder has the advantages of fast operation speed and good adaptability of the seed meter to the seeds. In recent years, it has become more and more popular at home and abroad, and it has gradually been popularized and used in a small part of my country. However, the fan is basically driven by the rear drive shaft of the tractor. When air suction seeding is carried out, the output of the tractor will stop when parking and turning around. It is driven by the ground wheel, and the slippage of the ground wheel may easily cause wheat fertilization, unstable seeding performance, and insufficient precision, etc.
As far as the current air suction seeder is concerned, it has not yet reached the expected goal, and there are still many parts that need to be redesigned and improved.

Embodiment 1

[0035] Example 1, see Figure 1-Figure 6 As shown, a kind of intelligent control hydraulically driven air-suction wheat sowing device includes a rotary cultivator 2 connected to the tractor 1, a fertilizer discharger 18 and a seed meter 17 connected to the rotary cultivator 2, and also includes a rotary cultivator located at The negative pressure fan 8 on the machine 2, the negative pressure fan 8 has double suction cups opposite to the air suction direction, and the double suction cups are connected with the air pipe of the seed meter 17.

[0036] As a preference, the negative pressure fan 8 is driven by a high-speed hydraulic motor 7, the fertilizer discharger 18 and the seed metering device 17 are respectively driven by a low-speed hydraulic motor I11 and a low-speed hydraulic motor II12, and each hydraulic motor is connected to the main controller 9 ; The high-speed hydraulic motor 7, low-speed hydraulic motor I11 and low-speed hydraulic motor II12 are all driven by the hy...

Embodiment 2

[0043] Example 2, see Figure 8 The difference between this embodiment and Embodiment 1 is that, on the basis of Embodiment 1, a pressure maintaining circuit is provided on the branch road of the hydraulic pump station driving the high-speed hydraulic motor 7 and the negative pressure fan 8. The pressure maintaining circuit includes a pressure sensor 4 installed at the air inlet of the negative pressure fan and an electro-hydraulic proportional valve 3 installed between the hydraulic pump station and the high-speed hydraulic motor 7, the pressure sensor 4, the electro-hydraulic proportional valve 3 It is electrically connected with the main controller 9.

[0044] In the branch where the high-speed hydraulic motor is connected to the fan, a pressure-holding circuit is designed. The purpose of setting up the pressure-holding circuit is to make the fan have a constant pressure, so as to prevent the tractor from turning and turning around due to unstable wind pressure and reduced ...

Embodiment 3

[0045] Embodiment 3, the difference between this embodiment and Embodiment 1 or Embodiment 2 is that, on the basis of Embodiment 1 or Embodiment 2, a photoelectric encoder 14 is installed at one end of the seeding shaft of the seed metering device 17 A photoelectric encoder 13 is installed at one end of the fertilizer discharge shaft of the fertilizer discharger 18, and the photoelectric encoder 13 and the photoelectric encoder 14 are respectively electrically connected to the main controller 9.

[0046] Ground wheel 16 is installed on the end both sides of rotary tiller 2, and photoelectric encoder 15 is installed on the rotating shaft of ground wheel 16, and described photoelectric encoder 15 is electrically connected with main controller 9. The ground wheels 16 are used for the forward operation of the rotary cultivator 2, consistent with the running speed of the tractor. The photoelectric encoder 15 measures the speed of the tractor 1 .

[0047] Install a photoelectric en...

Abstract

The invention discloses an intelligent control hydraulic-drive aspirated-air type wheat seeding device. The intelligent control hydraulic-drive aspirated-air type wheat seeding device comprises a rotary cultivator connected with a tractor, a fertilizer apparatus and a seedling apparatus which are connected with the rotary cultivator, and further comprises a negative-pressure type draught fan positioned on the rotary cultivator. The negative-pressure type draught fan is provided with a double-sucker with the adverse aspirated-air directions. The double-sucker is connected with an air pipe of the seeding apparatus. The negative-pressure type draught fan is driven by a high-speed hydraulic motor. The fertilizer apparatus and the seedling apparatus are driven by a low-speed hydraulic motor I and a low-speed hydraulic motor II, and each hydraulic motor is connected with a main controller. The high-speed hydraulic motor, the low-speed hydraulic motor I and the low-speed hydraulic motor II are driven by a hydraulic power pack on the tractor. The intelligent control hydraulic-drive aspirated-air type wheat seeding device is not manually operated by a person, and the artificial intelligentcontrol hydraulic drive is realized through the main controller and a man-machine interface. In the different driving speeds of the tractor, the revolving speed real-time tracking of seeding and fertilizing shafts is realized, and the uniform and accurate fertilizing and seeding can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural sowing equipment, in particular to an intelligently controlled hydraulically driven air-suction wheat sowing device. Background technique [0002] Wheat is an important food crop in my country, and sowing is a key link in wheat production, and the quality of sowing directly affects the yield of wheat. The air-suction wheat precision seeder has been widely used at home and abroad because of its strong seed adaptability, high seeding precision, and adaptability to high-speed operations. [0003] Traditional seed metering devices are mainly divided into two categories: mechanical type and air suction type. The air-suction seeding device is more accurate in seeding, and is suitable for sowing large-grained crops, such as corn and soybeans. For seeds with smaller particles like wheat, mechanical seed distribution devices are often used. The main advantages are the consistent displacement of eac...
