Description

 The invention relates to measuring instruments and can be used in agriculture, forestry, water management for linear rough measurements.

 Known measuring instruments for linear rough measurements: scaleless (compasses, calipers), scale (calipers with a scale, measuring rulers, tape measure), for linear measurements that do not require high accuracy - caliper tools.

 The caliper consists of a bar, fixed jaws, a frame with movable jaws, measuring scales.

 Roulettes are a steel or cloth tape, on the surface of which there is a scale. The tape is enclosed in a case.

 Measuring rulers are single-scale and two-scale, rigid and elastic.

 Scaleless tools are used to transfer linear measurements from the details of the object to the measured ruler and vice versa. Instruments, as a rule, consist of two movable legs (Ivanov A.I. Technical measurements, 2nd ed., Revised .- M .: Kolos, 1970).

 The closest in technical essence and the achieved effect to the claimed is a vernier caliper containing a rod with fixed jaws, frames with movable jaws and measuring scales (Ivanov A.I. Technical measurements, 2nd ed., Revised. - M .: Kolos, 1970 p. 78-79 - prototype).

 The main disadvantage of these devices in relation to the proposed one is that in agriculture, in particular in horticulture, vegetable growing, forestry and water management, when using them it is not possible to measure objects (diameters of the stem, tree trunk, etc.), also measure linear parameters of large sizes or simultaneously measure diameters, radii, etc. with one device or these instruments allow them to be measured slowly and laboriously.

 The technical result of the invention is the measurement of objects at a certain distance, for example, not closer than 1.5 m from the object; expansion of measurement capabilities, the range of measurement parameters (diameter, radius, height, width, depth); measurement of linear parameters of large sizes; ensuring the accessibility of points, for example, a tree trunk with highly ringed crowns, measurements; facilitating the physical efforts of man, increasing the productivity of measurements.

 This object is achieved in that the meter, including the elements of the device, vernier caliper, is made in the form of an elongated rod with a sponge and holes on it from the sponge to the opposite end through certain distances, and a frame moving with the sponge along the rod, with one hole made on the frame opposite the sponge; the holes are designed to install locking studs, as well as with measuring scales with a zero point on the rod from the end of the frame, at the moment the jaws touch, on the frame from the center of the hole, and a holder is rigidly mounted parallel to the jaws on the frame.

 In FIG. 1 shows a plant meter; in FIG. 2 and 3 - rod and frame; in FIG. 4 and 5 are diagrams of processes for measuring the diameter of a tree trunk and crown.

 Rod 1 and frame 2 are made elongated, for example, of light weight-tight tubes of small diameter and with holes 5, 6. The length of rod 1, for example, 180-200 cm, of the frame is 150-170 cm. Holes 5 on rod 1 (Fig. .2) are made at certain distances, for example, from the inner line of the jaw 3 through a 50 cm first hole, then every 25 cm from the first hole. On the frame 2 there is one hole 6 (Fig. 3) opposite the jaw 4. The holes 5 and 6 are made with the possibility of combining them and installing the locking stud 7 in them (Fig. 1). On the rod 1 is applied a measuring scale 8 (Fig. 1, 2) with the beginning of a zero reference from the end of the frame 2 at the moment of contact of the jaws 3 and 4 (Fig. 1). On the frame 2, a measuring scale 9 is plotted from the center of the hole 6 (Fig. 3). In parallel to the jaws 3 and 4 on the frame 2, a holder 10 is rigidly mounted (Fig. 3).

 The diameter of the tree trunk is measured as follows. The meter is held in a horizontal or inclined position for the end 9 (Fig. 4) of the rod 1 with the right hand, with the left hand, for the holder 10, with which the frame 2 is pushed back, is slightly larger than the barrel diameter. After the sponge 3 of the rod 1, the opposite side of the barrel is captured, and on the other hand, with the help of the holder 10, the frame 2 is brought to the barrel by the sponge 4 of the frame 2 until tangible contact. On the measuring scale 8 of the rod 1 at the intersection of the scale 8 with the frame 2, the barrel diameter is counted with a measurement accuracy of ± 0.25 cm.

 Similarly, the meter can be used to measure diameters, for example, watermelons, pumpkins, heads of cabbage and other plant and inorganic round and other objects located on the surface of the soil, in water or any solution with a neutral or aggressive environment.

 The size of the radius of the crown of the tree is determined as follows (Fig. 5).

 By moving the frame 2 along the rod 1, the necessary conditional length of the meter is selected. Combining the hole 6 on the frame 2 with the necessary hole 5 on the rod 1, insert the pin 7 into the hole 5-6. For example, the crown size (radius) is 2-2.5 m. In this case, the hole 6 on the frame is combined with the third hole 5 on bar from sponges. As a result, the rod 1 gives 1 m of length (50 cm to the first hole plus 50 cm to the third hole) plus 1.5 m the length of the frame 2 and a measuring instrument 2.5 m long is created. To measure the radius of the crown, the rod 3 is engaged or emphasized by the sponge 3 on the measured object (trunk, lateral branch) on one side at a height of approximately the middle of the crown (in diameter from the soil surface), and on the periphery of the crown, the measured object is visually combined at the point necessary for measurement with the measuring scale of frame 2, and a reference is taken, for example 1 , 2 m. Whence it follows that the size is measured of the second object (crown radius) is 2.2 m (1 m on the bar plus 1.2 m frame reading).

 A linearly extended meter can be used to measure the height, length, width, depth of various objects and environments.
