Изобретение относитс к области измерительной техники, служащей дл определени плотности различных материалов, н может быть использовано дл определени плотности хлопкового волокна непосредственно в бункере хлопкоуборочной машины.The invention relates to the field of measurement technology, which serves to determine the density of various materials, and it can be used to determine the density of cotton fiber directly in the bunker of a cotton harvesting machine.

Известно устройство дл определени плотности материала, содержащее корпус со щупом, нажимную руко тку со щтоком, взаимодействующую с корпусом посредством пружины, одним концом закрепленной в нем, измерительную щкалу, снабженную кольцевым унругим указателем. При этом щуп выполнен, изогнутым, а шкала нанесена на щток руко тки 1.A device for determining the density of a material is known, comprising a housing with a probe, a pressure handle with a brush, interacting with the housing by means of a spring fixed at one end, a measuring probe provided with an annular pointer. In this case, the probe is made, curved, and the scale is applied to the brush of the handle 1.

Дл определени плотности материала (грунта под шпалами) щуп вводилс в него нажимом на руко тку, шток при этом погружалс в корпус, а указатель перемещалс по шкале при взаимодействии с верхним основанием корпуса. В момент соприкосновени нижнего основани корпуса с поверхностью земли, т. е. при достижении определенной величины усили введени щупа в материал, производилось сн тие показаний со шкалы по указателю.To determine the density of the material (the soil under the sleepers), the probe was inserted into it by pressing on the handle, the rod was immersed in the housing, and the pointer moved along the scale when interacting with the upper base of the housing. At the moment of contact of the lower base of the body with the surface of the earth, i.e., when a certain amount of force was introduced to insert the probe into the material, the readings were taken from the scale according to the index.

Недостатком известного устройства вл етс неприменимость его в труднодоступных местах, где невозможно точно зафиксировать момент достижени заданного A disadvantage of the known device is its inapplicability in hard-to-reach places, where it is impossible to accurately fix the moment of reaching a given

усили введени щупа в материал, например , в бункере хлопкоуборочной машины. Кроме этого, форма щупа не позвол ет точно определить плотность хлопкового волокна .force of insertion of the probe in the material, for example, in the bunker of the cotton harvester. In addition, the shape of the probe does not accurately determine the density of cotton fiber.

Цель изобретени -устранение указанных недостатков, т. е. расширение технологических возможностей устройства и увеличение точности определени плотности.The purpose of the invention is to eliminate these drawbacks, i.e., to expand the technological capabilities of the device and to increase the accuracy of determining the density.

Цель достигаетс тем, что устройство снабжено световым индикатором, смонтированным в нажимной руко тке, один из контактов которого жестко укреплен в корпусе , а другой - на конце штока руко тки, а измерительна шкала с указателем расположена на щупе, при этом последний размещен соосно с корпусом.The goal is achieved by the fact that the device is equipped with a light indicator mounted in a pressure handle, one of the contacts of which is rigidly fixed in the housing, and the other at the end of the handle stem, and the measuring scale with the pointer is located on the probe. .

Кроме того, щуп снабжен сферическим наконечником.In addition, the probe is equipped with a spherical tip.

На фиг. 1 изображено предлагаемое устройство дл определени плотности материала , общий вид; на фиг. 2 - измерительна шкала, размещенна на щупе устройства .FIG. 1 shows the proposed device for determining the density of a material, general view; in fig. 2 - measuring scale placed on the device probe.

Claims

The device consists of: case 1; probe 2, coaxial with it, the end of which is provided with a spherical tip 3; push handle 4 with stem 5; a spring 6 mounted on the rod 5, by means of which the handle 4 interacts with the housing 1; a light indicator 7 with a power source 8 located in the handle 4; one pin 9 of the indicator is rigidly fixed in the housing, and the other pin 10 is at the end of the rod 5; a measuring scale located on the tongue 2 and equipped with a circular pointer II, which is mounted on the probe in a prestressed state, which makes it possible to record the scale readings after the load is removed by a 10 grip. The device works in the following way. Handle 4 creates an axial pressure on the mass of cotton, while w; yn 2 by its pack of 15 binder 3 deforms the cotton mass and is introduced in the pee until the deformation of the spring 6 ne reaches the distance between contacts 9 and 10. When when they are in contact, the light 20 indicator 7 is triggered. The probe 2 is drawn out of the fiber, while the ring pointer AND shows the depth of penetration of the black arrow into the pulp on the scale of the device. According to the indications of the scale and the calibration schedule, cotton density is determined. An annular pointer 11, moving along the probe 2 with some force, serves simultaneously as a guiding element that allows the insertion of the DZ probe into the cotton strictly perpendicular to its surface. The device allows controlling the quality of compaction of the cotton mass. Claim 1. Device for determining the density of the material, mainly cotton fiber in the cotton harvesting machine 40, comprising a housing with a probe, a nominal handle with a rod, interacting with the housing by means of a spring, one end fixed in it, a measuring scale fitted with an annular 45 with an elastic pointer, characterized in that, in order to expand the technological possibilities, it is equipped with a light indicator mounted in a push handle, one of the contacts of which is just 50 2. When Corp. determined with m horse etc. 1. 9/00, 35 fastened in the housing, and the other - ka rod handle, and the measuring rasnolozhsna with arrows on the dipstick, the latter being coaxial with that serves catfish. The device according to p. I, characterized in that, in order to increase the accuracy of the tree, the probe is equipped with a spherical nanic.
