Description
Предлагаемая полезная модель относится к методам и средствам определения фракционного состава измельченной соломы после работы измельчителей зерноуборочных комбайнов.The proposed utility model relates to methods and means for determining the fractional composition of crushed straw after the operation of the grinders of combine harvesters.
Известна методика отбора проб измельченной соломы [ГОСТ 28301-2007. Комбайны зерноуборочные. Методы испытаний [Текст]. - введ. 2010-01-01. - М.: Межгосударственный совет по стандартизации, метрологии и сертификации; - М.: Изд-во «Стандартинформ», 2010. - 35 с].The known method of sampling shredded straw [GOST 28301-2007. Combine harvesters. Test methods [Text]. - enter 2010-01-01. - M .: Interstate Council for Standardization, Metrology and Certification; - M .: Publishing house "Standartinform", 2010. - 35 s].
Согласно агротехническим требованиям количество измельченных фракций до 10 см должно составлять 75-80%.According to agrotechnical requirements, the amount of crushed fractions up to 10 cm should be 75-80%.
После прохода по полю зерноуборочного комбайна, оборудованного измельчителем, отбирают пробы измельченной соломы при помощи прямоугольной рамки размером 50×50 см, которую укладывают на поверхность поля и внутри рамки собирают измельченную солому. Необходимо отобрать 8-10 проб при трехкратной повторности и разобрать эти пробы на фракции. Собранную измельченную солому вручную разбирают на фракции до 100 мм, 100-150 мм, свыше 150 мм согласно ТУ.After passing through the field of a combine harvester equipped with a grinder, samples of crushed straw are taken with a rectangular frame 50 × 50 cm in size, which is laid on the field surface and crushed straw is collected inside the frame. It is necessary to take 8-10 samples with triplicate and disassemble these samples into fractions. The collected crushed straw is manually disassembled into fractions up to 100 mm, 100-150 mm, over 150 mm according to TU.
Измеряют длину каждой соломины линейкой с последующим распределением ее по размерным фракциям для взвешивания и процентного расчета фракционного состава измельченной соломы.The length of each straw is measured with a ruler, followed by its distribution by size fractions for weighing and the percentage calculation of the fractional composition of crushed straw.
Недостаток известного метода заключается в следующем: измерение длины соломин всех проб процесс трудоемкий и требует много времени.The disadvantage of this method is as follows: measuring the length of the straws of all samples is a laborious process and requires a lot of time.
Цель полезной модели - сокращение затрат ручного труда и времени на разбор каждой пробы измельченной соломы на фракции.The purpose of the utility model is to reduce the cost of manual labor and the time required to analyze each sample of chopped straw into fractions.
Предлагаемое устройство для определения количества фракционного состава измельченной соломы за зерноуборочными комбайнами изображено на чертеже.The proposed device for determining the amount of fractional composition of crushed straw for combine harvesters is shown in the drawing.
Предлагаемое устройство представляет собой проборазборник в виде пятигранного стакана 1 с ручкой 2, на внутренних боковых гранях которого нанесены риски 3: первое деление 100 мм, второе 150 мм. Для удобства извлечения соломин из проборазборника, одна грань изготовлена высотой 100 мм, две грани срезаны под углом на высоте первого деления.The proposed device is a sampler in the form of a five-sided glass 1 with a handle 2, on the inner side faces of which risks 3 are applied: the first division is 100 mm, the second is 150 mm. For the convenience of extracting straws from the sampler, one face is made 100 mm high, two faces are cut at an angle at the height of the first division.
Принцип работы проборазборного устройства заключается в следующем: берется порция из пробы измельченной соломы и помещается в устройство. Делая колебательные движения, добиваемся распределения соломин в межгранное пространство проборазборного устройства. Затем, извлекая уложенные по длине соломины, раскладываем их по фракциям: сначала соломины длина которых более 150 мм, затем 100-150 мм и остальные, длина которых менее 100 мм.The principle of operation of the sampling device is as follows: a portion is taken from the sample of chopped straw and placed in the device. By making oscillatory movements, we achieve the distribution of straws in the inter-facetted space of the sampling device. Then, extracting the straws laid along the length, we arrange them into fractions: first, the straws are more than 150 mm long, then 100-150 mm and the rest, the length of which is less than 100 mm.
Благодаря устройству сокращается продолжительность времени, уменьшается количество человек на разбор каждой пробы по фракционному составу измельченной соломы.Thanks to the device, the length of time is reduced, the number of people to analyze each sample according to the fractional composition of crushed straw is reduced.
