Multi-purpose air suction type mixed bean precision seeder and seeding test device

Abstract

The invention discloses a multi-purpose air suction type mixed bean precision seeder and a seeding test device, and relates to the technical field of agricultural machinery. The problems that a seeder is poor in adaptability to mixed beans of different varieties and different sizes, cannot realize multiple purposes, is low in utilization rate, low in mechanization degree, low in operation efficiency, low in seeding precision, complex in structure, non-universality and the like are solved. The multi-purpose air suction type mixed bean precision seeder comprises a trolley and a test bed, the lower surface of the trolley is connected with the test bed through a trolley driving wheel and a trolley driven wheel, an air suction seeding device and a seed throwing device connected with the air suction seeding device are arranged in the trolley, a seed box is arranged on the upper surface of the trolley, a control box is connected with one side of the trolley, a negative pressure fan is connected with the other side of the trolley, and the negative pressure fan is connected with the air suction seed sowing device through an air pipe. The multi-purpose air suction type mixed bean precision seeder meets seeding requirements of mixed beans with different specifications by adjusting the hole size of the seeding device, and operation efficiency and the seeding precision are high.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multipurpose air-suction precision seeder for miscellaneous beans and a seeding test device. Background technique [0002] The sowing of miscellaneous beans such as soybeans, kidney beans, mung beans, adzuki beans, black beans, etc. is still stagnant in the backward stage of manual, animal power and seeding machines. The speed, accuracy and intelligence level of miscellaneous bean seeding machines in my country have a certain gap compared with developed countries. To narrow the gap, breakthroughs must be made for each key technology. The precision sowing process of miscellaneous beans is a systematic project, including three main links of seed arrangement, seeding, and implantation. Each link is closely related and affects each other. In order to obtain higher seeding performance, that is, good qualification index, reseeding index, missing seeding index and coeff...
