Design and Experiment of Asymmetrical Planting Implement for Garlic Upright Planter
Abstract
In order to solve the problems of low upright degree and low working efficiency of garlic planter, the planting implement with asymmetrical structure suitable for continuous garlic planter was designed, in order to adapt to the continuous change of the horizontal speed of planting implement during the planting process and keeping the garlic seed upright state. The action process of planting implement and soil on garlic seed was analyzed, and the equation for the contour curve at the bottom of the seed hole and the simulation system of garlic upright planting device were established. According to the role of the planting implement in different working stages, a two-stage planting implement structure with different upper and lower cone angles was proposed, and the upper cone angle was determined to be 20°. Through the single-factor simulation experiment of the influence of some factors on the symmetries of the shape of the seed-hole, the shape of bottom of the seed-hole and the upright degree of planting garlic, it was determined that the opening mode of the planting implement was one side forward opening, the opening moment was when the planting implement moved to the lowest point, and the center of rotation of the opening side was 110 mm above the apex of the bottom of planting implement and 15 mm behind the apex of bottom of the planting implement. The structure of the planting implement was optimized to be an asymmetric structure and the corresponding parameters were determined by the simulation analysis of the action process of the planting implement on the garlic seed. Four-factor and three-level orthogonal simulation experiments were carried out to study the effects of three working parameters and lower cone angle of planting implement on the upright degree of garlic seed and the optimal combination parameter was determined as the velocity ratio of 1.12, the horizontal distance of opening of 29.69 mm, the opening time of 0.51 s, the lower cone angle of the planting implement of 40.90°, and the upright degree of planted garlic of 72.84°. A test bed of garlic upright planting device was built to validate the simulation results which were verified by experiments. The test result showed that the upright degree of planted garlic was 68.66°, which indicated that the established simulation system was correct and the simulation test result was practical and reliable.
