Embodiment 1

[0036] This embodiment provides an electric drive control distributor for rice and wheat collection and row unit, such as Figure 1-Figure 3 As shown, it includes a detachably connected gate valve passage 1 and a distributor cover 2 , and a plurality of gate valve passages 1 are evenly arranged along the circumference of the distributor cover 2 . The distributor cover plate 2 is connected with the top of the gate valve channel 1 through the upper connection 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 channels 1 and the upper connecting plate 7 are connected by a pin 4, and the gate valve channel 1, the bottom plate 3, the upper connecting plate 7 and the distributor cover plate 2 form a distribution c...

Embodiment 2

[0049] This embodiment provides a control method for the electric drive control distributor of the rice and wheat collection and row unit, including:

[0050] The positive pressure airflow sends the airflow 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 the distributor cover plate 2, and form a uniform seed flow through the separation of the conical protrusion 201 and the partition 202 Enter the entrance of the corresponding gate valve passage 1, and the valve 103 is in an 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 clockwise 90°, and now the valve 103 is in a closed state, and the mixture of seeds and air is blocked by the valve 103.

[0052] Each gate valve channel 1 has a motor 105 to control the opening or closing of the valve 103. During the sowing operation, multiple rows can be c...

Abstract

The invention discloses a rice and wheat centralized seeding unit electric drive control distributor and a method. According to the technical field, the device comprises a distributor cover plate andgate valve channels evenly distributed in the circumferential direction of the edge of the distributor cover plate, a bottom plate is installed at the bottoms of the gate valve channels, and a distribution cavity is formed among the gate valve channels, the bottom plate and the distributor cover plate. A cone-shaped body is arranged in the distribution cavity and is connected with a corrugated pipe penetrating through the interior of the cone-shaped body. Valves are installed at the ends, connected with the distribution cavity, of the gate valve channels and can be opened or closed under the action of a power source. According to the distributor and the method, crops such as rice, wheat and the like can be uniformly distributed into rows, so that precise uniform sowing with different widths is realized, closing can be controlled row by row, and the operation performance and the working efficiency of a machine are improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery research, in particular to an electrically driven control distributor and method for a rice and wheat collecting and discharging unit. Background technique [0002] At present, most of the rice and wheat seeders are mechanical seeders, which have the disadvantages of small working width, low working speed, high seed fragmentation rate, and cannot be matched with large and medium-sized tractors. With the development of moderate-scale land management, agricultural production has higher and higher requirements for the efficiency, precision and intelligence of machine tools. 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 adaptability to seeds, high speed and wide width, simple structure and high seeding efficiency, and has gradually become the d...
