[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Embodiment 1
[0026] Refer to Figure 1 , Figure 1 This is the structural schematic diagram of an ultrasonic scanning device for identifying the species of ragweed seeds provided by an embodiment of the present utility model. As Figure 1 shown, this embodiment includes: a sliding table 101, a geophone string 102, an ultrasonic transducer 103 and a vertical track 104; wherein, the sliding table includes: a moving device 1011 and a bracket 1012;
[0027] The moving device abuts against the bracket;
[0028] The geophone string is arranged below the bracket;
[0029] The ultrasonic transducer is embedded at the lower and central position of the bracket;
[0030] The moving device is connected to the vertical track.
[0031] In a specific embodiment, the ultrasonic transducer emits ultrasonic waves. When there is an entity at a certain point (X, Y) on the detection surface, the geophone string can receive the reflected wave, then there is point cloud data at the three-dimensional coordinates (X, Y, Z). On the contrary, when there is no physical object at a certain point on the detection surface, the geophone string does not receive the reflected wave information, and there is no point cloud data at this point. By moving the sliding table up and down, the point cloud data on different detection surfaces Z can be obtained. Combining the point cloud data obtained from all detection surfaces in the whole process forms the point cloud data. In this embodiment, the point cloud data is presented in the form of a black and white image.
[0032] Each image only has defect waves and normal waves. Since the defect wave is a cavity, there is no feedback information after the ultrasonic wave is emitted. Since the normal wave has an entity, feedback information can be received after the ultrasonic wave is emitted. The defect wave is black and the normal wave is white, as Figure 2 , 3 shown, Figure 2, 3 Correspond to the internal and external structures of ragweed seeds detected at different heights respectively, and clear internal and external contours can be seen.
[0033] As an improvement to the above solution, it further includes: an encoder 105; wherein, the encoder is disposed inside the mobile device.
[0034] In a specific embodiment, the sliding table can only move reciprocally up and down. When the sliding table travels an actual distance S, the pulley of the encoder rotates a certain angle, and then this rotation angle is converted into an electrical signal Z. By analyzing the electrical signal, the specific position can be obtained. Since the frequency of the ultrasonic wave is constant, the height of the detection surface will change as the sliding table moves.
[0035] As an improvement to the above solution, the vertical track includes: a transmission shaft 405, a linear track 406, and a pulley running track 402; the encoder includes: an encoder chip 407 and an encoder roller 401; the mobile device includes: a motor 403 and a moving slider 404;
[0036] The motor, the transmission shaft, and the moving slider are disposed inside the linear track, and the motor is connected to the top end of the transmission shaft, and the moving slider is connected to the transmission shaft so that the moving slider can move up and down on the transmission shaft; wherein, the moving slider is externally connected to the bracket;
[0037] The encoder chip is connected to the encoder pulley, the encoder chip is disposed on the moving slider, and the encoder pulley is disposed on the roller pulley running track.
[0038] In a specific embodiment, as Figure 4 shown, the vertical track includes the linear track and the pulley running track of the sliding table, and the encoder chip and the encoder roller of the encoder are fixed in the moving slider of the sliding table. When the motor is started, the transmission shaft can rotate, driving the moving slider in the sliding table to perform a linear motion up and down. Since the encoder is fixed together with the moving slider, the encoder and the moving slider move synchronously. Due to the movement of the encoder, the encoder roller rotates a corresponding angle under the action of friction.
[0039] As an improvement to the above solution, it further includes: a tray 106; wherein, the tray is used to place the ragweed seed identification sample.
[0040] As an improvement to the above solution, the motor is specifically: a stepper motor.
[0041] In a specific embodiment, the mobile device is a linear moving component controlled by a stepper motor, and the encoder is a component that converts the traveling distance of the stepper motor into an electrical signal by means of pulley rolling, and the encoder is fixed on the sliding table.
[0042] As an improvement of the above solution, the ultrasonic transducer emits a shock wave of 20 Hz.
[0043] In a specific embodiment, the ultrasonic transducer releases a shock wave of 20 Hz to form a black-and-white two-dimensional image at a height position 0.01 mm above the tray.
[0044] This embodiment includes: a sliding table, a geophone string, an ultrasonic transducer, and a vertical track; wherein, the sliding table includes: a moving device and a bracket; the moving device abuts against the bracket; the geophone string is arranged below the bracket; the ultrasonic transducer is embedded below the bracket and at the central position; the moving device is connected to the vertical track. In this application, the ultrasonic transducer and the geophone string are used to scan and detect the samples for identifying ragweed seeds. The moving device of the sliding table can be used to adjust the detection height of the ultrasonic wave. Since the ultrasonic transducer and the geophone string are arranged on the bracket of the sliding table, when the sliding table moves, the ultrasonic transducer and the geophone string also move along with the bracket, thereby realizing the adjustment of the detection height of the ultrasonic wave. This utility model uses ultrasonic scanning technology, which can obtain the internal and external structures of ragweed seeds during the identification of ragweed seed species, and is beneficial to improving the accuracy of identifying ragweed seed species. At the same time, this utility model can obtain the complete internal and external characteristics of ragweed seeds without damaging the original identification samples, subverting the traditional external morphological feature identification and anatomical identification.
[0045] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
