Description

Technical Field

[0001] This utility model relates to the field of fruit measurement technology, specifically a fruit longitudinal and transverse diameter measuring device. Background Technology

[0002] The fruit longitudinal and transverse diameter measuring instrument is an agricultural / food testing tool specifically designed for the precise measurement of the longitudinal and transverse diameters of fruits. Its core function is to quantify the external dimensions of fruits to help determine their growth status, maturity, and commercial grade, or to provide data support for agricultural research, production management, and quality inspection.

[0003] In existing technologies, fruits come in various irregular shapes, and traditional devices cannot effectively measure the longitudinal and transverse diameters of fruits from different angles, leading to larger measurement errors. Because most fruits are irregularly shaped, a fixed orientation may not accurately measure the actual maximum size, especially for deformed or curved fruits. The applicability is also narrow, making it difficult to adapt to fruits with complex shapes such as strawberries and mangoes. It is also difficult to accurately measure irregularly shaped fruits of the same species, and may damage small or soft fruits. In high-precision scenarios, it cannot meet the needs of scientific research for analyzing the symmetry of fruit morphology, assessing regularity for high-standard grading, and long-term growth tracking. Furthermore, the operation efficiency is low, requiring repeated adjustments to the fruit position, and different operators may introduce data deviations due to subjective judgment. It is only suitable for scenarios with low precision requirements and uniform fruit morphology. Utility Model Content

[0004] The purpose of this invention is to provide a fruit longitudinal and transverse diameter measuring device to solve the problem mentioned in the background art, which is unable to effectively measure the longitudinal and transverse diameters of fruits at different angles, resulting in large measurement errors and data deviations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fruit longitudinal and transverse diameter measuring instrument, including a measuring instrument body, a support base fixedly connected to the bottom of the measuring instrument body, a transverse diameter scale set on the top of the measuring instrument body, a transverse diameter measuring component set inside the measuring instrument body, an adjustment component set on the measuring instrument body, a longitudinal diameter measuring stop set on the adjustment component, a transverse diameter measuring stop and a placement plate set on the adjustment component, a longitudinal diameter scale set on the adjustment component, a placement plate set on the measuring instrument body, a fixed mounting base fixedly connected to the bottom of the measuring instrument body, a first motor fixedly connected to the fixed mounting base, a rotating worm fixedly connected to the output end of the first motor, a rotating connecting rod rotatably connected inside the measuring instrument body, a rotating worm wheel fixedly connected to the rotating connecting rod, the rotating worm wheel meshing with the rotating worm, and a placement plate fixedly connected to the rotating connecting rod. The rotating worm is driven to rotate inside the fixed mounting base by the first motor, and the rotating connecting rod rotates inside the measuring instrument body under the condition that the rotating worm is meshed with the rotating worm wheel.

[0006] In the preferred embodiment of this technical solution, the measuring instrument body has a groove at the corresponding position of the rotating connecting rod, and the rotating connecting rod rotates inside the groove.

[0007] In the preferred embodiment of this technical solution, two fixed mounting bases are provided, and the two fixed mounting bases are symmetrically fixedly connected to the bottom of the measuring instrument body.

[0008] Based on the preferred embodiment of this technical solution, the transverse diameter measuring component includes a second motor fixedly connected to one side of the measuring instrument body, a fixed mounting shaft fixedly connected inside the measuring instrument body, a rotating threaded rod fixedly connected to the output end of the second motor, and a sliding adjustment seat threadedly connected to the rotating threaded rod. The rotating threaded rod is driven to rotate inside the measuring instrument body by the second motor, and the sliding adjustment seat is driven to slide inside the measuring instrument body by the rotating threaded rod being threadedly connected to the sliding adjustment seat.

[0009] In a preferred embodiment of this technical solution, the measuring instrument body has a sliding groove at a corresponding position on the sliding adjustment seat, and the sliding adjustment seat slides inside the sliding groove.

[0010] According to the preferred embodiment of this technical solution, the adjustment component includes an electric telescopic rod fixedly connected to the sliding adjustment seat, a fixed support seat fixedly connected to the electric telescopic rod, a connecting mounting seat fixedly connected to one side of the measuring instrument body, a sliding toothed plate slidably connected inside the connecting mounting seat, a rotating mounting plate rotatably connected inside the connecting mounting seat, a third motor fixedly connected to the rotating mounting plate, a rotating gear fixedly connected to the rotating mounting plate, and the rotating gear meshing with the sliding toothed plate.

[0011] Based on the preferred embodiment of this technical solution, two electric telescopic rods are provided, and the two electric telescopic rods are symmetrically and fixedly connected between the fixed support base and the sliding adjustment base.

[0012] In the preferred embodiment of this technical solution, the connecting mounting base has a groove at the corresponding position of the sliding toothed plate, and the sliding toothed plate slides inside the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By driving the first motor to rotate the worm gear and mesh with the worm wheel, the rotating connecting rod and the placement plate rotate at multiple angles. This allows for adjustment of the angle of irregularly shaped, deformed, or bent fruits, accurately finding the actual maximum size, significantly reducing measurement errors, and solving the problem of large deviations in traditional fixed-direction measurements. It has wide applicability, eliminating the need for repeated manual adjustments to the fruit position. It can be adapted to fruits with complex shapes such as strawberries and mangoes, as well as irregularly shaped fruits of the same type. It also avoids damage to small or soft fruits caused by manual operation. At the same time, automated angle adjustment replaces manual operation, improving operational efficiency and reducing data deviations caused by subjective judgments of different operators. It can meet the refined needs of scientific research for fruit morphological symmetry analysis, high-standard grading for regularity assessment, and long-term growth tracking, and is no longer limited to scenarios with low precision requirements and uniform fruit shapes.

[0014] 2. The electric telescopic rod in the assembly can drive the fixed support base and the longitudinal diameter measuring scale to adjust up and down, adapting to fruits of different heights such as short and flat citrus and tall and long cucumbers. This solves the problem of traditional devices being unable to adapt to fruits with complex shapes, ensuring that the longitudinal diameter measuring scale is accurately aligned with the top and bottom of the fruit. The two symmetrical electric telescopic rods ensure that the fixed support base is evenly stressed when raised and lowered, avoiding tilting that could cause deviation in the longitudinal diameter measurement direction. This ensures accurate readings of the longitudinal diameter scale and reduces the deviations that are prone to occur with traditional manual adjustments. At the same time, the third motor drives the rotating gear and the sliding toothed plate to mesh and drive the rotating mounting plate for fine adjustment, making the longitudinal and transverse diameter measuring scales fit the irregularly shaped fruits better. This eliminates the need for repeated manual adjustments, improving operational efficiency and avoiding manual contact that could damage small or soft fruits. This meets the needs of refined scenarios such as scientific research and high-standard grading. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment including a measuring instrument body 1, a support base 2 fixedly connected to the bottom of the measuring instrument body 1, a transverse diameter scale 3 disposed on the top of the measuring instrument body 1, a transverse diameter measuring component disposed inside the measuring instrument body 1, an adjustment component disposed on the measuring instrument body 1, a longitudinal diameter measuring stop 5 disposed on the adjustment component, a transverse diameter measuring stop 6 disposed on the adjustment component and a placement plate 7, a longitudinal diameter scale 4 disposed on the adjustment component, a placement plate 7 disposed on the measuring instrument body 1, a fixed mounting base 801 fixedly connected to the bottom of the measuring instrument body 1, a first motor 802 fixedly connected to the fixed mounting base 801, and a fixedly connected... A rotating worm gear 803 is connected to the output end of a motor 802. A rotating connecting rod 804 is rotatably connected inside the measuring instrument body 1. A rotating worm wheel 805 is fixedly connected to the rotating connecting rod 804. The rotating worm wheel 805 is meshed with the rotating worm gear 803. A placement plate 7 is fixedly connected to the rotating connecting rod 804. The rotating worm gear 803 is driven to rotate inside the fixed mounting base 801 by the first motor 802. With the rotating worm gear 803 and the rotating worm wheel 805 meshing, the rotating connecting rod 804, which is fixed with the rotating worm wheel 805, will rotate inside the measuring instrument body 1. This will cause the placement plate 7 connected to the rotating connecting rod 804 to rotate at multiple angles, adjusting the fruit angle to a suitable measurement position.

[0019] Please see Figure 2-3 A further solution based on this embodiment is as follows: The measuring instrument body 1 has a groove at the corresponding position of the rotating connecting rod 804. The rotating connecting rod 804 rotates inside the groove. By opening a dedicated groove for the rotating connecting rod 804 on the measuring instrument body 1, a clear motion trajectory restriction can be provided for the rotation of the rotating connecting rod 804, avoiding lateral offset or jamming during rotation, ensuring that the rotating connecting rod 804 always rotates around a fixed axis, thereby ensuring that the fruit on the placement plate 7 will not change position due to the offset of the connecting rod, and ensuring that the relative positions of the longitudinal diameter measuring stop 5 and the transverse diameter measuring stop 6 with the fruit are always accurate.

[0020] Please see Figure 2-3 A further solution based on this embodiment is as follows: two fixed mounting bases 801 are provided, and the two fixed mounting bases 801 are symmetrically fixedly connected to the bottom of the measuring instrument body 1. By symmetrically fixing the two fixed mounting bases 801 to the bottom of the measuring instrument body 1, the weight of the transmission components such as the first motor 802 and the rotating worm gear 803 can be evenly distributed to both sides of the measuring instrument body 1, avoiding tilting or center of gravity shift of the measuring instrument body 1 due to excessive force on one side, and ensuring that the entire device remains stable during placement and use.

[0021] Please see Figure 2-3 A further solution based on this embodiment is as follows: The transverse diameter measuring component includes a second motor 806 fixedly connected to one side of the measuring instrument body 1, a fixed mounting shaft 807 fixedly connected inside the measuring instrument body 1, a rotating threaded rod 808 fixedly connected to the output end of the second motor 806, and a sliding adjustment seat 809 threadedly connected to the rotating threaded rod 808. The second motor 806 drives the rotating threaded rod 808 to rotate inside the measuring instrument body 1. Under the condition that the rotating threaded rod 808 and the sliding adjustment seat 809 are threadedly connected, the sliding adjustment seat 809 is driven to slide inside the measuring instrument body 1. The second motor 806 drives the rotating threaded rod 808 to rotate, and the sliding adjustment seat 809 is driven to slide inside the measuring instrument body 1 by the thread transmission principle. This can realize the automated position adjustment of the transverse diameter measuring stop 6 indirectly connected to the sliding adjustment seat 809, replacing the traditional manual operation of pushing the stop. This not only reduces the intensity of manual labor, but also controls the movement distance of the sliding adjustment seat 809 through the precise speed of the motor, avoiding the deviation of the stop position caused by uneven force during manual operation.

[0022] Please see Figure 2-3A further solution based on this embodiment is as follows: the measuring instrument body 1 has a groove at the corresponding position of the sliding adjustment seat 809, and the sliding adjustment seat 809 slides inside the groove. By opening a groove on the measuring instrument body 1 for the sliding adjustment seat 809, a clear guiding effect can be provided for the sliding of the sliding adjustment seat 809, ensuring that the sliding adjustment seat 809 can only move in a straight line along the direction of the groove, avoiding lateral offset or rotation, thereby ensuring that the transverse diameter measuring stop 6 and the longitudinal diameter measuring stop 5 connected to the sliding adjustment seat 809 always maintain the correct measuring direction.

[0023] Please see Figure 4-5 A further solution based on this embodiment is as follows: The adjustment component includes an electric telescopic rod 901 fixedly connected to the sliding adjustment seat 809, a fixed support seat 902 fixedly connected to the electric telescopic rod 901, a connecting mounting seat 903 fixedly connected to one side of the measuring instrument body 1, a sliding toothed plate 904 slidably connected inside the connecting mounting seat 903, a rotating mounting plate 905 rotatably connected inside the connecting mounting seat 903, a third motor 906 fixedly connected to the rotating mounting plate 905, and a rotating gear 907 fixedly connected to the rotating mounting plate 905. The rotating gear 907 is meshed with the sliding toothed plate 904. Through the telescopic movement of the electric telescopic rod 901, the fixed support seat 902 and the longitudinal diameter measuring stop 5 connected to the fixed support seat 902 can be driven to achieve vertical height adjustment, which can be adapted to fruits of different heights and sizes, such as short and flat citrus fruits and tall and long cucumbers, ensuring that the longitudinal diameter measuring stop 5 can be accurately aligned with the top and bottom of the fruit.

[0024] Please see Figure 4-5 A further solution based on this embodiment is as follows: Two electric telescopic rods 901 are provided, and the two electric telescopic rods 901 are symmetrically fixedly connected between the fixed support base 902 and the sliding adjustment base 809. By symmetrically connecting the two electric telescopic rods 901 between the fixed support base 902 and the sliding adjustment base 809, the fixed support base 902 can be subjected to uniform pushing or pulling forces from both sides during the lifting and lowering process. This avoids the fixed support base 902 tilting due to the force on one side of the electric telescopic rod 901, thereby ensuring that the longitudinal diameter measuring stop 5 connected to the fixed support base 902 always remains in a vertical state and will not deviate from the longitudinal diameter measurement direction due to tilting, thus ensuring the accuracy of the data read by the longitudinal diameter scale 4.

[0025] Please see Figure 4-5A further solution based on this embodiment is as follows: the connecting mounting base 903 has a groove at the corresponding position of the sliding toothed plate 904, and the sliding toothed plate 904 slides inside the groove. By opening a groove for the sliding toothed plate 904 on the connecting mounting base 903, a precise guide trajectory can be provided for the sliding of the sliding toothed plate 904, ensuring that the sliding toothed plate 904 can only move in a straight line along the direction of the groove, avoiding lateral deviation or jamming, thereby ensuring that the rotating gear 907 meshing with the sliding toothed plate 904 can be stably transmitted, driving the rotating mounting plate 905 to precisely adjust its position, so that the longitudinal diameter measuring stop 5 and the transverse diameter measuring stop 6 can be accurately aligned with the fruit measurement point.

[0026] Working principle: The first motor 802 is started, and its output drives the rotating worm gear 803 to rotate within the fixed mounting base 801. Because the rotating worm gear 803 meshes with the rotating worm wheel 805, it drives the rotating connecting rod 804, which is fixed to the rotating worm wheel 805, to rotate within the measuring device body 1. This causes the placement plate 7 connected to the rotating connecting rod 804 to rotate at multiple angles. Simultaneously, a dedicated groove on the measuring device body 1 for the rotating connecting rod 804 restricts its movement trajectory, preventing deviation and jamming, ensuring the stability of the fruit position on the placement plate 7, and adjusting it to a suitable measurement angle. Furthermore, the two symmetrically fixed mounting seats 801 evenly distribute the weight of the transmission components, ensuring the overall stability of the equipment. After the angle adjustment is completed, the second motor 806 of the transverse diameter measuring component is started, driving the rotating threaded rod 808 to rotate under the support of the fixed mounting shaft 807. The threaded transmission drives the sliding adjustment seat 809 to slide linearly along the slide groove on the measuring body 1. The transverse diameter measuring stop 6, which is indirectly connected to the sliding adjustment seat 809, moves accordingly, precisely fitting the side of the fruit. Then, the adjustment component starts to work. The electric telescopic rod 901 extends and retracts, driving the fixed support seat 902 and the longitudinal diameter measuring stop 5 to adjust up and down to adapt to fruits of different heights, ensuring alignment with the top and bottom of the fruit. The two symmetrical electric telescopic rods 901 ensure that the fixed support seat 902 does not tilt, maintaining the verticality of the longitudinal diameter measuring stop 5. The third motor 906 is started, driving the rotating gear 907 to rotate and mesh with the sliding toothed plate 904. The sliding toothed plate 904 slides along the groove of the connecting mounting base 903, driving the rotating mounting plate 905 to make fine adjustments, so that the longitudinal diameter measuring stop 5 and the transverse diameter measuring stop 6 fit the fruit better. Finally, the transverse diameter and longitudinal diameter data of the fruit are read through the transverse diameter scale 3 on the top of the measuring instrument body 1 and the longitudinal diameter scale 4 on the adjustment component, completing the accurate measurement.
