Description
(54) УСТРОЙСТВО ДЛЯ ВЫДЕЛЕНИЯ СЕМЯН НАВЕСКИ ИЗ ПОЧВЕННОЙ(54) DEVICE FOR ISOLATION OF SEEDS HANGING FROM SOIL
этом вставка на три четверти погружена в раствор плотной жидкости. Навеску образца после отмывки мелкозема и высушивани , где наход тс семена с оставшейс почвой, осторожно всыпают в вставку и перемешивают стекл нной палочкой. Неорганическа фракци оседает на дно емкости, а органическа вместе с семенами сорн ков остаетс в съемной вставке. Приподнима вставку, под нее подвод т уловитель 7, плотно прижимают его к стенке и вместе с ней извлекают из раствора плотной жидкости. Затем со стенок полой вставки смывают из промывалки или тубуса на уловитель оставшиес семена. Семена сорных растений, наход щиес на уловителе, высушивают и разбирают по видам.This insert is three-quarters immersed in a solution of a dense liquid. After washing the fine-grained soil and drying, where the seeds are with the remaining soil, the sample is gently poured into the insert and stirred with a glass rod. The inorganic fraction settles to the bottom of the tank, and the organic fraction, together with the seeds of the weeds, remains in the removable insert. Lift the insert, the trap 7 is brought under it, it is pressed tightly against the wall and together with it is removed from the solution of a dense liquid. Then, from the walls of the hollow insert, wash the remaining seeds out of the washer or tube onto the trap. The seeds of weed plants located on the catcher are dried and dismantled by species.
Плотную жидкость в емкости 2 замен ют на новую после обработки 50-60 образцов.The dense liquid in the tank 2 is replaced with a new one after processing 50-60 samples.
Каркас 8 уловител обт нут сеткой с диаметром чеек 0,25 мм.The skeleton 8 of the catcher is covered with a mesh with a cell diameter of 0.25 mm.
Предмет изобретени Subject invention
Устройство дл выделени сем н из почвенной навески, содержашее емкость и сетчатый уловитель, отличающеес тем, что, с целью ускорени процесса выделени сем н, емкость выполнена с цилиндрической горловиной , переход щей в конусообразную, имеющей на стыке цилиндрической и конусообразной частей горловины сплошной кольцевой выступ, на который установлена пола вставка.A device for separating seeds from a soil hinge, containing a tank and a mesh trap, characterized in that, in order to speed up the process of seed extraction, the tank is made with a cylindrical neck, which becomes conical, having a continuous annular projection at the junction of the cylindrical and conical parts of the neck. On which the floor is installed.
