Description

Technical Field

[0001] The invention belongs to the technical field of particle size measurement, and particularly discloses a particle size measuring device for small-size fruits / seeds of trees. Background Art

[0002] The particle size of tree fruits is one of the important commercial traits and is also an important trait that forestry technicians are concerned about. The measurement of tree fruit particle size is currently mainly done using an ordinary ruler. If the data requires precision, a vernier caliper is used, which requires multiple sampling measurements of individual fruit grains, and then the data is averaged and calculated. This method is slow and inefficient.

[0003] In addition, the morphology and size of tree seeds are an important indicator of tree seed quality. It not only affects the seed weight, germination ability, and stress resistance, but is also directly related to the survival ability of seedlings and the growth of seedlings. Therefore, the morphology and size of tree seeds are one of the important indicators for observing tree seed morphology. Screening seeds with uniform morphology and size is an important measure to improve the efficiency of tree seed use and ensure uniform seedling emergence. Among them, the particle size of tree seeds is the core indicator for measuring their morphology and size. At present, the particle size measurement of tree seeds is mainly done manually using a vernier caliper to measure single seeds, which has relatively low measurement efficiency.

[0004] The above-mentioned measurements of both the fruit and seed particle sizes of trees all use vernier calipers for single-grain measurement, which not only has problems such as low measurement efficiency and cumbersome subsequent data processing, but also for ordinary fruits / seeds with a particle size of more than 20 mm (such as walnuts, dates, etc.), the measurement error is still within a controllable range. When measuring small-sized fruits / seeds with a particle size of 5-20 mm (such as Elaeagnus angustifolia, Pinus tabulaeformis, Platycladus orientalis, Prunus dahurica, Quercus liaotungensis, etc.), if vernier calipers are used for measurement, it is not easy to fix the fruit between the main scale and the vernier by hand, and the error is large. For tiny fruits / seeds below 5 mm (such as sea buckthorn, Zanthoxylum bungeanum, etc.), the accuracy of the vernier caliper cannot meet actual needs, and more precise instruments or sample statistics are generally used for measurement. Summary of the Invention

[0005] The purpose of the present invention is to provide a tree small-size fruit / seed particle size measuring device with higher measurement efficiency, simpler operation and more accurate results, which is particularly suitable for tree small-size fruit / seed with a particle size of 5-20 mm.

[0006] To achieve the above-mentioned purpose, the present invention provides a particle size measuring device for small-size fruits / seeds of trees, comprising a box body, a baffle and a measuring ruler; a rectangular or square groove is provided in the box body; the four corners of the groove are inwardly protruding right-angled blocks; the side length of the right-angled block is 5 mm; the baffle is provided with a transverse through hole, both ends of which are slidably connected to the transverse side walls of the groove; the position of the transverse through hole corresponds to the longitudinal side wall of the groove; the measuring ruler passes through the transverse through hole, both ends of which are slidably connected to the longitudinal side walls of the groove, a scale value is provided on the upper surface, an initial scale value is 0 and is aligned with the edge of the right-angled block, and a graduation value is 1 mm; a scale value is provided on the longitudinal side wall of the groove, an initial scale value is 5 mm, an end scale value is 20 mm, a graduation value is 1 mm, and the distance between the end scale value and the right-angled block is the width value of the measuring ruler.

[0007] Furthermore, the above-mentioned tree small-size fruit / seed particle size measuring device also includes a box cover rotatably connected to the box body.

[0008] Furthermore, the box body and the box cover are both made of wood; and metal anti-wear sheets are provided at the positions where the grooves are slidably connected to the baffle and the measuring ruler.

[0009] Furthermore, the box body and the box cover are rotatably connected via a hinge.

[0010] Furthermore, the width of the measuring ruler is 10 mm.

[0011] The beneficial effects of the present invention are:

[0012] Based on the particle size of the fruit / seed to be measured, the baffle and measuring ruler are moved so that the baffle, measuring ruler, and right-angled blocks in the groove form a measurement space that can accommodate the fruit to be measured. The fruit to be measured is placed in the measurement space, and the baffle and measuring ruler are moved to clamp the fruit to be measured. The corresponding values ​​on the measuring ruler and the longitudinal sidewalls of the groove are read to obtain the particle size of the fruit / seed to be measured (including the horizontal and vertical diameters). This avoids the error caused by manually holding the fruit to be measured, improves measurement accuracy, simplifies the operation process, and improves measurement efficiency. In addition, multiple fruits to be measured can be placed side by side in the measurement space, and the measured value is divided by the number of fruits to be measured to obtain the average value of the fruits to be measured.

[0017] This embodiment provides a particle size measuring device for small-size fruits / seeds of trees, comprising a box body 1, a baffle 2, and a measuring ruler 3. A rectangular or square groove is provided in the box body 1. The four corners of the groove are right-angled blocks 4 protruding inward. Since the minimum particle size of the fruit / seed 100 to be measured is 5 mm, the side length of the right-angled block 4 is 5 mm. The baffle 2 is provided with a transverse through hole 2.1, the two ends of which are slidably connected to the transverse side wall of the groove. The position of the transverse through hole 2.1 corresponds to the longitudinal side wall of the groove. The measuring ruler 3 passes through the box body 1. The transverse through hole 2.1 is slidably connected to the longitudinal side walls of the groove at both ends, and a scale value is set on the upper surface. The initial scale value is 0 and is aligned with the edge of the right-angle stopper, and the graduation value is 1mm; the longitudinal side wall of the groove is also provided with a scale value, the initial scale value is 5mm, the end scale value is 20mm, and the graduation value is 1mm. The distance between the end scale value and the right-angle stopper 4 is the width value of the measuring ruler 3. When the measuring ruler 3 slides to the bottom end of the transverse through hole 2.1, the upper edge is flush with the end scale value 20mm.

[0018] According to the particle size of the fruit / seed 100 to be measured, the baffle 2 and measuring ruler 3 are moved so that the baffle 2, measuring ruler 3, and the right-angled block 4 in the groove form a measurement space that can accommodate the fruit / seed 100 to be measured. The fruit / seed 100 to be measured is placed in the measurement space, and the baffle 2 and measuring ruler 3 are moved to clamp the fruit / seed 100 to be measured. The corresponding values ​​on the measuring ruler 3 and the longitudinal side wall of the groove are read to obtain the particle size (including the horizontal and vertical diameters) of the fruit / seed 100 to be measured. This avoids the error caused by manually holding the fruit to be measured, improves measurement accuracy, simplifies the operation process, and improves measurement efficiency. In addition, multiple fruits / seeds 100 to be measured can be placed side by side in the measurement space, and the measured value is divided by the number of fruits 100 to be measured to obtain the average particle size of the fruits / seeds 100 to be measured.

[0019] Furthermore, the above-mentioned tree small-size fruit / seed particle size measuring device further comprises a box cover 5 rotatably connected to the box body 1. When use is finished, the box cover 5 can be flipped and fastened to the box body 1 to avoid bumping against the baffle 2 and the measuring ruler 3 during storage.

[0020] Furthermore, to reduce weight, both the box body 1 and the lid 5 are made of wood. A metal anti-wear sheet 6 is installed where the groove, baffle 2, and measuring ruler 3 slide together to reduce damage and wear to the inner wall of the groove caused by repeated sliding of baffle 2 and measuring ruler 3, thereby ensuring measurement accuracy. The metal anti-wear sheet 6 can be made of steel, iron, or the like.

[0021] Furthermore, the box body 1 and the box cover 5 are rotatably connected via a hinge 7. After the measurement is completed, the box cover and the box body can be sealed for storage.

[0022] Furthermore, the width of the measuring ruler 3 is 10 mm.

[0023] The measuring device of the present invention can also be used to measure small-sized fruits and crop seeds, and has a wide range of applications.

[0024] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
