Treatment device for crop seeds

Abstract

The invention relates to a treatment device for crop seeds, which greatly improves the screening efficiency and screening effect of the seeds, and improves a germination rate of the seeds. The top ofa screening cylinder is provided with a charging port, the middle of the screening cylinder is provided with a separating port, and the bottom of the screening cylinder is provided with a returning port and a discharging port; a filter net is arranged between the separating port and the charging port, and the aperture of the filter net is larger than the particle size of the seeds; the separatingport is communicated with a fan by a separating pipe, and the fan is further communicated with a cloth bag; the returning port is closer to the separating port than the discharging port, the discharging port is movably connected to a material baffle plate, and the material baffle plate is driven by a first power device to move horizontally; the bottom of a returning cylinder is communicated with the returning port of the screening cylinder by a first returning pipe, and the top of the returning cylinder is communicated with the charging port of the screening cylinder by a second returning pipe; a feeding screw rod is rotatably connected in a feeding channel in the returning cylinder, and the feeding screw rod can be driven by a second power device to rotate; a mounting rod is connected ina mixing cylinder along the axial direction, blades sleeve the periphery of the mounting rod, and the mounting rod is driven by a third power device to rotate.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a crop seed treatment device. Background technique [0002] The seeds contain fine sand and some unsaturated or dry seeds. If these bad seeds and impurities are not selected in advance, the germination rate of the seeds will be greatly affected. The traditional seed selection method is mostly carried out manually, which is time-consuming and laborious, and it cannot guarantee that the impurities and shriveled seeds in the seeds can be fully selected. In addition, in order to increase the germination rate of the seeds and enable the seeds to be produced normally, it is necessary to spray the auxiliary liquid on the surface of the seeds after the selection is completed. However, since these two treatment methods are independent of each other, the process transfer takes a long time, prolonging the treatment period of the seeds.
