Abstract

FIELD: agriculture. SUBSTANCE: device relates to hop production, and is intended for determining the dimensional characteristics of hop cone scales. The device is assembled on a common flat base, on which a stand is installed for placing the measured scale of a freshly harvested hop cone. A daylight source is located inside the stand. A lower plate is installed on the stand, on which the test scale is placed. The test scale is pressed with an upper plate, and a coordinate plate is placed on the upper plate, which has three degrees of freedom. The coordinate plate is placed symmetrically with respect to the scale, orienting along the Y-Y and X-X axes drawn on the coordinate plate. When measuring the length of the scale and the length of the scale tip, a micrometer with a stand is placed in a hole on the base located to the right along the X-X axis, and when measuring the width of the scale, the micrometer with a stand is placed in a hole on the base located along the Y-Y axis. EFFECT: increasing the accuracy and productivity of the operation of determining the elastic properties of a freshly harvested hop cone. 6 cl, 4 dwg

Description

The device is related to the agricultural industry, in particular to hop production, and is intended to determine the dimensional characteristics of hop cone scales. A method for simultaneously measuring the color and linear dimensions of easily deformable objects—the width, length, and height of a hop cone—is known. This method measures the hop cone's dimensions as follows. The cone is suspended vertically using a clamp on a device at a minimum distance from a vertically positioned flexible data carrier, which can be moved left and right relative to the vertically suspended cone. The flexible data carrier is provided with vertical and horizontal scales, allowing for the measurement of the hop cone's width, length, and height, respectively. The width of the flexible data carrier should be wider than the maximum statistical height of the hop cone. After positioning the cone relative to the flexible data carrier at the closest possible distance, the operator determines the width, length, and height of the hop cone using the flexible data carrier's vertical and horizontal scales. This method improves the accuracy of sorting freshly harvested hop cones by color while simultaneously increasing the accuracy of measuring their linear dimensions. It also improves the throughput of both color sorting and linear dimension measurement. However, it cannot be used to determine the geometric dimensions of hop cone scales, as they differ in size, shape, and other morphological characteristics [1]. The closest technical equivalent to the proposed invention is a device for measuring the elasticity of hop cones assembled on a common base, onto which the test cone is placed. A flat horizontal clamp is applied to the cone from above, exerting pressure on the test cone using a weight. A rectangular grid consisting of horizontal and vertical lines and an axis of symmetry is applied to the upper surface of the base. During measurement, the clamp presses down on the cone and deforms it. The magnitude of the cone deformation is monitored using a scale on the base and is an indicator of the cone's elasticity. This device improves the accuracy and productivity of determining the elastic properties of freshly harvested hop cones. A disadvantage of this device is that it cannot be used to determine the geometric dimensions of hop cone scales, as they differ in size, shape, and other morphological characteristics [2]. The aim of the proposed invention is to develop a device for determining the geometric characteristics of hop cone scales. The term "geometric characteristics of a hop cone scale" refers to: H (length), b (width), and h (length of the tip of the hop cone scale), as well as the ratio of the scale width to its length (Fig. 1). Knowing the dimensions of these characteristics allows one to identify the hop variety. These scale characteristics vary among different hop varieties, and their values can be used to determine the variety of a given hop cone. The problem is as follows. Scientists have bred many different varieties of hops, and in practice, the need to classify a specific batch of hop cones as belonging to a particular variety constantly arises. Hop cones of different varieties are identical in morphological structure, and it is very difficult to visually (organoleptically) determine the variety of a given batch of hops. Reference [3] recommends identifying hop varieties by the following three characteristics: the size of the hop cone scale, the ratio of the hop cone's width to its length, and the length of the hop cone scale tip—that is, by the geometric characteristics of an individual scale. This document merely recommends using the listed characteristics as distinguishing features, but does not specify how to quantify them. Another difficulty is that the hop cone scale is small, easily deformed, and often has an irregular configuration, which complicates the measurement process and can introduce significant errors into the results of instrumental measurements. Fig. 1 shows (top view) the geometric characteristics of a hop cone scale that must be measured using the proposed device, and where the following designations are adopted: H is the length of the scale; b is the width of the scale; h is the length of the tip of the scale. In Fig. 2 the design of the device for determining the geometric characteristics of a hop cone scale is shown in schematic form (side view), where the following designations are adopted: 1 - rectangular base; 2 - stand; 3 - light source; 4 - lower plate; 5 - test scale; 6 - upper plate; 7 - coordinate plate; 8 - pin; 9 - micrometer; 10 - clamp; 11 - stand; 12 - clamp screw; 13 - lock screw; Z-Z - common vertical axis of the device; the vertical arrow shows the direction of movement of the micrometer with the clamp in the vertical plane; the horizontal arrow indicates the direction of movement of the micrometer with the stand in the horizontal plane.
