Embodiment 1

[0036] This embodiment provides an electric drive control distributor for rice and wheat collection and row units, such as Figure 1-Figure 3 As shown, it includes a gate valve channel 1 and a distributor cover plate 2 that are detachably connected, and a plurality of gate valve channels 1 are evenly spaced along the circumference of the distributor cover plate 2 . The distributor cover plate 2 is connected with the top of the gate valve channel 1 through the upper connecting plate 7, and the bottom plate 3 is installed at the bottom of the gate valve channel 1. A conical body 5 is arranged in the space formed between the gate valve channel 1 , the upper connecting plate 7 and the bottom plate 3 , and the conical body 5 is connected with the bellows 6 .

[0037] Further, the adjacent gate valve channel 1 and the upper connecting plate 7 are connected by the pin shaft 4, the gate valve channel 1, the bottom plate 3, the upper connecting plate 7 and the distributor cover plate 2...

Embodiment 2

[0049] The present embodiment provides a control method for an electric drive control distributor of a rice-wheat collection and row unit, including:

[0050] The positive pressure air flow sends the air flow and the mixture of rice and wheat seeds into the distribution chamber through the bellows 6, and the rice and wheat seeds rise to contact with the distributor cover plate 2, and form a uniform seed flow through the separation effect of the conical protrusion 201 and the partition plate 202. Enter the entrance of the corresponding gate valve channel 1, and the valve 103 is in the open state at this time.

[0051] When a gate valve channel 1 of a certain row needs to be closed, the controller controls the motor 105 to rotate 90° clockwise. At this time, the shutter 103 is in a closed state, and the mixture of seeds and airflow is blocked by the shutter 103 .

[0052] Each gate valve channel 1 has a motor 105 to control the opening or closing of the valve 103. During the sow...

Abstract

The invention discloses an electric drive control distributor and a method for a rice-wheat collecting and rowing unit. A distribution chamber is formed between the gate valve channel, the bottom plate, and the distributor cover plate; a cone is installed inside the distribution chamber, and the cone is connected with a bellows running through its interior; one end of the gate valve channel connected to the distribution chamber is installed with a shutter, the shutter It can be opened or closed under the action of the power source. The invention can evenly distribute crops such as rice and wheat into rows, so as to achieve precise and uniform sowing of different widths, and can be controlled and closed row by row, thereby improving the working performance and working efficiency of the machine.

Description

technical field [0001] The invention relates to the field of agricultural machinery research, in particular to an electric drive control distributor and method for a rice-wheat collection and row unit. Background technique [0002] At present, most rice and wheat seeders are mechanical seeders, which have shortcomings such as small operating width, low operating speed, high seed breaking rate, and cannot be used with large and medium-sized tractors. With the development of moderately large-scale land management, agricultural production has higher and higher requirements for operating efficiency, precision, and intelligence of machinery and tools, and traditional mechanical seeding equipment is developing in the direction of large-scale, precise, pneumatic, and intelligent. [0003] The air-supplied collector has the characteristics of wide range of seeds, high speed and wide width, simple structure and high sowing efficiency, and has gradually become the development trend of...
