Hand-operated rolling seeding disc

Abstract

The invention discloses a hand-operated rolling seeding disc, which comprises a seed storage disc, rotating shafts, seeding holes, seed grooves, a rocker rod, a crank, a rocker rod fixing plate and a handle and is characterized in that a plurality of seeding holes are uniformly ranged on the seed storage disc and are through holes, positions of the lower part of the seed storage disc corresponding to the seeding holes are provided with the rotating shafts with the same line number as the seeding holes, the seed grooves which correspond to the positions of the seeding holes and have the same number as the seeding holes are arranged on the rotating shafts, one end of each rotating shaft is provided with the crank rod, the other end of the crank rod is respectively connected onto the rocker rod fixing plate, the rocker rod fixing plate is connected with the handle, and the other end of the middle rotating shaft is connected with the rocker rod. The hand-operated rolling seeding disc is particularly applicable to the current production situation of the agriculture in China, the work intensity of the agriculture seeding is effectively reduced, and the production efficiency is improved. The hand-operated rolling seeding disc has the advantages that the structure is simple and practical, and in addition, the precise seeding requirements can be met.

Description

technical field [0001] The invention relates to a sowing disc, in particular to a hand-operated rolling sowing disc. Background technique [0002] China is a large agricultural country. The current situation of China's agriculture is that the degree of agricultural mechanization is low, and agriculture is still a labor-intensive industry. Seeding trays are widely used in agricultural sowing. Seeding trays are of great significance to the liberation of agricultural labor. Improving the efficiency and quality of sowing, and rationally adjusting the density of sowing are crucial to the output of agricultural products. Among the existing sowing trays, the sowing tray disclosed by the patent application number 95227282.2 and the sowing tray disclosed by the patent No. 200320113054. The upper and lower plate structures are adopted, and holes are opened on the upper and lower baffles. By staggering the upper and lower baffles or removing the baffles in the middle, the seeds...

[0002] China is a large agricultural country. The current situation of China's agriculture is that the degree of agricultural mechanization is low, and agriculture is still a labor-intensive industry. Seeding trays are widely used in agricultural sowing. Seeding trays are of great significance to the liberation of agricultural labor. Improving the efficiency and quality of sowing, and rationally adjusting the density of sowing are crucial to the output of agricultural products. Among the existing sowing trays, the sowing tray disclosed by the patent application number 95227282.2 and the sowing tray disclosed by the patent No. 200320113054. The upper and lower plate structures are adopted, and holes are opened on the upper and lower baffles. By staggering the upper and lower baffles or removing the baffles in the middle, the seeds on the plates fall to complete the sowing work. Such a seeding plate not only sows The efficiency is low, and it is easy for the board to be stuck by the seeds. At the same time, it is difficult to accurately control the density of the sowing manually. However, the double adjustable precision seeding disc disclosed in the patent No. 200420051549.5 and the corn sowing disclosed in the patent No. 200720090521.6 Machine sowing discs, they can complete fast and precise control of sowing, but they must be used in conjunction with mechanical equipment, which has the disadvantages of complex structure and low production cost
