Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a volume measuring device for an object with an irregular shape. Background Art

[0002] In agricultural and forestry research, it is often necessary to measure the volume of objects. However, most common objects are irregular in shape, which makes volume measurement relatively difficult. At the same time, since the surface of some objects is permeable or absorbent, it is impossible to use the drainage method for volume measurement. Although the existing 3D laser scanning technology has high measurement accuracy and strong versatility, the purchase cost of 3D laser scanners is very high, and the operation process of a single measurement is cumbersome, which is not convenient to carry when working outdoors. Summary of the invention

[0003] The utility model aims to provide a volume measuring device for objects with irregular shapes in view of the defects of the prior art.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The irregular-shaped object volume measuring device described in the utility model comprises:

[0006] A first container containing a measuring ball, the first container opening is downward, a connecting channel is vertically extended downward from the opening, and the lower end of the connecting channel is connected to an arc-shaped expansion port that gradually expands outward from top to bottom;

[0007] A partition plate, movably inserted in the middle of the connecting channel;

[0008] The second container has an opening facing upward and is adapted to be docked on the edge of the arc-shaped expansion port, and the chamber volume of the second container after docking with the arc-shaped expansion port is equal to the inner cavity volume of the first container.

[0009] Specifically, the first container and the second container are both transparent containers, and the measuring ball has a diameter of 2 mm and a density of 1 g / cm 3 The solid sphere has an inner diameter of 15 mm.

[0010] Furthermore, gripping handles are provided on the outer walls of the first container and the second container to facilitate gripping operations.

[0011] Furthermore, an annular slot is circumferentially arranged on the outer side of the mouth of the second container, and a guide sleeve is fixedly inserted in the annular slot. The guide sleeve is a cylindrical body, and its inner diameter is consistent with the outer diameter of the mouth of the arc-shaped expansion, which is convenient for guiding the arc-shaped expansion so that it can be easily and accurately docked with the second container.

[0012] Furthermore, the arc-shaped expansion mouth and the edge of the second container are both rough surfaces, which can effectively increase the friction between the contact surfaces of the two while ensuring that the arc-shaped expansion mouth and the second container are tightly connected.

[0013] Furthermore, a plurality of vertically upward supporting columns are evenly distributed at the bottom of the chamber of the second container, and the supporting columns are used to support the object to be measured placed in the second container, so that the object to be measured is suspended in the second container, thereby making the volume measurement of the object to be measured without blind spots, greatly improving the measurement accuracy.

[0014] The utility model has the advantages of simple structure, easy operation, small size, easy storage, and convenient carrying and transfer. The first container and the second container are easily connected by adapting the second container to the arc-shaped expansion port and opening the partition plate movably inserted in the middle of the connecting channel, so that the measuring ball contained in the first container falls into the second container and fills the space around the object to be measured placed in the second container, so that the volume of the object to be measured is determined according to the reduction of the measuring ball in the first container, and the volume measurement of irregular objects is easily achieved. At the same time, the measuring ball can also effectively avoid being absorbed by the object to be measured with permeability or water absorption on the surface, so as to ensure the accuracy of the measurement.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 , 2As shown, the irregular-shaped object volume measuring device described in the utility model comprises a first container 1, a partition plate 2 and a second container 3. Among them, the first container 1 opens downward, and a connecting channel 4 is vertically extended downward at its opening, and the lower end of the connecting channel 4 is connected to an arc-shaped expansion 5 that gradually expands outward from top to bottom, and the first container 1, the connecting channel 4 and the arc-shaped expansion 5 are coaxially arranged and integrally formed; the partition plate 2 is movably inserted in the middle of the connecting channel 4 to block the connecting channel 4; the second container 3 is a wide-mouth container with an opening facing upward, in which the object to be measured is placed, and the upper opening of the second container 3 can be adapted to be connected to the lower edge of the arc-shaped expansion 5, and when the second container 3 is connected to the arc-shaped expansion 5, the volume of the closed chamber inside is just equal to the volume of the inner cavity of the first container 1. In addition, the first container 1 also contains a measuring ball 6 for volume replacement with the object to be measured in the second container 3. The diameter of the measuring ball 6 is smaller than the cross-sectional diameter of the inner cavity of the connecting channel 4, so that when the partition plate 2 is opened, the measuring ball 6 can easily pass through the connecting channel 4 and fall into the second container 3.

[0019] Specifically, the first container 1 and the second container 3 are both transparent containers (can be transparent acrylic containers or transparent glass containers), so that the situation inside the containers can be clearly observed when measuring the volume of the object to be measured.

[0020] The measuring ball 6 has a diameter of 2 mm and a density of 1 g / cm 3 The solid spheres, as the volume displacement material, will not be absorbed by the object to be measured (such as dried mushrooms) with permeable or water-absorbent surface, and each measuring ball 6 has uniform particle size, good fluidity, and constant weight per unit volume.

[0021] At this time, the inner diameter of the connecting channel 4 should be 15 mm, which is much smaller than the inner cavity diameter of the first container 1, thereby forming a narrow-mouthed channel relative to the first container 1. In this way, the error introduced when the partition plate 2 is inserted into the connecting channel 4 for sealing will be reduced as much as possible, and it can ensure that the measuring ball 6 can easily pass through the connecting channel 4, avoiding the jamming phenomenon of being unable to fall naturally from the connecting channel 4, so that the measuring ball 6 can fully contact with the object to be measured, thereby improving the volume measurement accuracy of the object to be measured.

[0022] Furthermore, in order to facilitate the accurate docking of the second container 3 and the arc-shaped flared opening 5, an annular slot 7 with an opening facing upward may be provided circumferentially on the outer side of the mouth edge of the second container 3, and a guide sleeve 8 may be fixedly inserted in the annular slot 7. The guide sleeve 8 is a cylindrical barrel, and the diameter of the inner barrel cavity thereof should be consistent with the outer diameter of the lower mouth edge of the arc-shaped flared opening 5, so as to ensure that the arc-shaped flared opening 5 can be inserted into the guide sleeve 8, so as to facilitate the correction of the arc-shaped flared opening 5 so that it can be easily and accurately docked with the upper mouth edge of the second container 3. In addition, the mouth edges of the arc-shaped flared opening 5 and the second container 3 may be both set to rough surfaces, so as to ensure that the arc-shaped flared opening 5 and the second container 3 are tightly docked, and the friction between the contact surfaces of the two can be effectively increased.

[0023] Furthermore, since some objects to be measured may have an inward depression at the bottom when placed in the second container 3, the measuring ball 6 cannot be filled in the depression, which greatly reduces the accuracy of the volume measurement of the objects to be measured. Therefore, multiple vertical support columns 10 can be evenly distributed at the bottom of the chamber of the second container 3, and the objects to be measured placed in the second container 3 can be supported by the support columns 10, so that the objects to be measured are suspended in the second container 3, thereby making the volume measurement of the objects to be measured without dead angles, greatly improving the accuracy of the measurement. In addition, in order to facilitate the holding and operation of the first container 1 and the second container 3, a gripping handle 12 can be provided on the outer wall of the first container 1 and the second container 3.

[0024] When in use, first fill the first container 1 with the measuring ball 6, and operate the partition plate 2 to seal the measuring ball 6 in the first container 1; then place the object to be measured on the support column 10 in the second container 3, and insert the guide sleeve 8 at the opening of the second container 3; then insert the arc-shaped expansion 5 of the first container 1 into the guide sleeve 8 downward, and make the lower edge of the arc-shaped expansion 5 fit and connect with the upper edge of the second container 3; after all operations are completed, the partition plate 2 can be pulled outward to make the measuring ball 6 in the first container 1 fall freely to the second container 3. In the second container 3, after the second container is filled with measuring balls 6, the measuring balls 6 completely surround the object to be measured, and the space occupied by the object to be measured will cause a part of the measuring balls 6 to remain in the first container 1 and cannot fall. At this time, the partition plate 2 is inserted into the connecting channel 6 again, so as to separate the remaining measuring balls 6 in the first container 1 from the measuring balls 6 in the second container 3. In this way, the volume of the object to be measured can be obtained by weighing the remaining measuring balls 6 in the first container 1. Since the measuring balls 6 have a diameter of 2 mm and a density of 1 g / cm 3 The solid sphere, so the density of the measuring sphere 6 per unit volume is 0.7405 g / cm 3According to the weight of the remaining measuring balls 6 in the first container 1, the volume of the measured object can be calculated using V=m / ρ (a deformation of the density formula, where V is the overall volume of the remaining measuring balls 6 in the first container 1, m is the overall mass of the remaining measuring balls 6 in the first container 1, and ρ is the density of the measuring balls 6 per unit volume), thereby easily realizing the volume measurement of irregular objects.
