specific Embodiment

[0028] Take the soybean pneumatic sowing device pulled by a tractor as an example. When in use, the frame 1 is connected with the tractor. When the tractor advances, the rotary blade on the rotary tiller 2 firstly performs rotary tillage on the soil. After that, the valve controller 6 sends an electric signal to the pneumatic two-position three-way directional control valve 8, opens the channel between the air pipe II7 and the air pipe I11, and inflates the left chamber of the pneumatic double-acting horizontal bar cylinder 17, and the pneumatic double-acting horizontal bar cylinder The piston rod of 17 moves to the right, and the pull switch plate 14 moves to the right, so that the seeding pipe 9 is communicated with the seeding pipe 18 through the seed hole 15, and the fertilizer feeding pipe 10 is communicated with the seeding pipe 18 through the fat hole 16. The seed in the seed box 3 enters the seeding pipe 18 through the seeding pipe 9 and the through-seeding hole 15, and...

Abstract

The invention discloses a seeding device for soybeans. The device includes a machine frame, the machine frame is provided with an installation box for fixing a seeding and fertilizing synchronous switch, the seeding and fertilizing synchronous switch includes a shell, and a spring and a switch board which are arranged in the shell, and two ends of the spring are respectively connected to the shelland the switch board; the switch board is connected to a piston rod of a pneumatic double-acting single-rod cylinder, a rod cavity in the pneumatic double-acting single-rod cylinder is connected to agas outlet of a two-position three-way pneumatic control valve, and a gas inlet of the two-position three-way pneumatic control valve is connected to a gas tank; the upper and lower end surfaces of the shell are both provided with two through holes, the two through holes in the upper end surface are respectively connected to a seed box and a fertilizer box, and the upper end of a seeding pipe isprovided with two branch pipes respectively connected to the two through holes in the lower end surface; and the switch board is provided with two up-down through holes, that is, the two up-down through holes are respectively a seed passing hole and a fertilizer passing hole. According to the device, seeding and fertilization can be synchronously performed after rotary tillage is performed on soil, the seeding amount, the fertilization amount and the seed spacing can be accurately controlled, and the seeding quality can be ensured.

Description

technical field [0001] The invention belongs to the fields of sowing device technology and pneumatic control, and in particular relates to a soybean sowing device. Background technique [0002] Soybean is an important strategic material. As a food crop, oil crop, and economic crop, it is of great significance to our country. Soybean is a crop with high economic value, and its main value is food, medicine, feed and industrial use. Therefore, it is cultivated all over my country, and Heilongjiang soybean is the most famous. Although my country's soybean production ranks among the top in the world, as one of the largest soybean consumers and importers, the benefits of soybean production are not high. [0003] When soybeans are planted, higher planting conditions are required, such as the depth of soil turning, the depth of covering soil, and the ration of chemical fertilizers. Excessive chemical fertilizers may cause soybean seeds to die due to insufficient respiration, reduc...
