Steering wheel type cavitation seeder

Abstract

The invention provides a rudder wheel type caving seeder, which includes a sowing wheel, and is characterized in that: the sowing wheel includes a wheel shaft, a cam, a wheel cover and a steering wheel, wherein the cam and the wheel shaft are fixedly connected with a key, and the steering wheel includes a wheel that is slidably installed on the wheel shaft The roulette, the two rings protruding from the roulette, and the multiple burrower assemblies radially evenly arranged on the rim, the multiple burrower assemblies divide the rim into several sectors, and the roulette cover is fixed on the cam On the top, each sector of the cover forms a number of fan-shaped cross-section seeding chambers, and a fixed position of the wheel cover is provided with a seed drop port, so that the seeding chambers communicate with the seed meter. Because the seeder adopts the hole-forming seeding system composed of the cam-slider-injector assembly and the system of continuous seed supply, division of seeds, and hole-forming seeding system, the seeding and seeding are accurate and reliable, and there is no cavity and no pinching. Soil, no film, and the sowing depth can be adjusted by adjusting the frame. It is easy to install and maintain, and has excellent performance.

Description

technical field [0001] The invention provides a steering wheel type hole-forming seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] The main problems of existing scientific research or product-type film-covered hole seeders are: 1. Poor adaptability, which is only suitable for sandy loam. Because the soil condition is greatly affected by the soil condition, when the soil viscosity is high, soil will be trapped and cause leakage. 2. The principle of the brush type sorting mechanism is backward, and the secondary sorting accuracy is poor and the reliability is poor; 3. The sowing depth cannot be adjusted; 4. The opening device of the burrower is easy to tear the film. Contents of the invention [0003] The object of the present invention is to provide a steer wheel type caving seeder capable of overcoming the above-mentioned defects, sorting, caving and seeding reliable, and excellent in performance. specifically is: [0...
