Detailed Description
The invention relates to a plugboard air-suction type adjustable seeder which is structurally characterized in that:
referring to fig. 1 and 2, a top block 4 is arranged on the side wall of the rotary drum of the seeder to push the movable partition plate 2 to move; the movable partition plate 2 can move along the slot of the inner wall of the air chamber 1, and when the movable partition plate 2 enters the air chamber 1, two cavities, namely a vacuum cavity and a non-vacuum cavity, are formed by the movable partition plate 2 and the fixed partition plate 3 in the air chamber (1).
In specific implementation, as shown in fig. 1 and 2, the movable partition plate 2 is composed of an inserting plate 21, an upright post 22, a blocking sleeve 23, a sliding sleeve 24 and a pressure spring 25, wherein the inserting plate 21 is fixedly connected with the sliding sleeve 23, the upright post 22 is fixedly connected on the bottom outer wall of the air chamber 1, and the pressure spring 25, the sliding sleeve 24 and the blocking sleeve 23 are sleeved on the upright post in sequence; as shown in fig. 2 and fig. 3, the top block 4 is composed of a connecting plate 41 and a convex body 42, the connecting plate 41 is connected with the side wall of the roller, the convex body 42 is fixedly connected with the connecting plate 41, the convex body 42 is trapezoid, the inclination of the front side is small, the plug board 21 is pushed slowly and is not easy to be blocked, the inclination of the rear side is large, the plug board 21 is reset rapidly, the longer the upper plane straight line is, the longer the residence time of the plug board 21 in the air chamber 1 is, and the number of seeds in each hole is effectively increased; the more the number of the jacking blocks 4 are installed on the same circumference of the corresponding plugboards 21 on the side wall of the roller, the smaller the sowing hole pitch is.
The operation process comprises the following steps:
before sowing, top blocks 4 with corresponding numbers and shapes are arranged on the side wall of a roller of a sowing machine according to the requirements of a planting mode and the number of sowing grains (when the speed of the roller and the rotating speed of a seed sucking disc are unchanged, the more the top blocks 4 are arranged on the same circumference of the side wall of the roller, the smaller the hole spacing for sowing is, and when the top blocks 4 push the inserting plate 21 to be completely inserted into the air chamber 1, the longer the time for cutting off an air source is, the more the number of grains in each hole is), so that the adjustment of the hole spacing for sowing and the number of grains in each hole in the sowing process is realized.
During sowing, as the operation of the planter, the implement pulls the bunch planting wheel to rotate, the seed sucking disc is driven by the transmission shaft to rotate relative to the seed chamber and the air chamber 1, negative pressure is applied to the cavity of the air chamber 1, the seed sucking disc fully adsorbs seeds in the seed chamber and brings the seeds out of the seed chamber, when the seed sucking disc rotates to the lower area of the air chamber 1, the inserting plate 21 in the movable partition plate 2 moves along the inserting slot of the inner wall of the air chamber due to the action of the ejecting block 4 on the rotating roller side plate, the air chamber is divided into two cavities, an air source of the lower cavity is cut off, the movable partition plate 2 and the fixed partition plate 3 divide the air chamber into two cavities, the upper cavity is a vacuum area, the lower cavity is a non-vacuum area, when the seed sucking disc rotates to the non-vacuum area of the lower cavity, the seeds disappear due to negative pressure of the seed sucking disc by means of dead weight, the seeding process is realized, when the ejecting block 4 leaves the inserting plate 21, the inserting plate 21 resets under the action of the pressure spring 25, the lower cavity of the air chamber 1 recovers the negative pressure, and when the seed sucking disc rotates to pass through the area.
