Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please refer to Figure 1-4 The present invention provides an ultrasonic testing device for detecting crops at different heights, comprising a conveyor belt, an infrared sensor 5, and a testing mechanism.

[0031] The conveyor belt is horizontally positioned for continuously transporting products to be inspected. The conveyor belt includes a base 1, two rotating rollers 2, a belt body 3, and a second motor 4. The base 1 has a U-shaped frame structure. The two rotating rollers 2 are rotatably mounted at both ends of the upper part of the base 1, and are arranged parallel to each other on the same horizontal plane. The belt body 3 is fitted onto the two rotating rollers 2, forming a stable synchronous belt for transmission. The second motor 4 is mounted on one side of the base 1, and its output end is connected to one end of one of the rotating rollers 2. The second motor 4 can drive the rotating roller 2 to rotate, thereby driving the belt body 3 to move.

[0032] The infrared sensor 5 is disposed on one side of the conveyor belt and is used to detect the height of the items on the conveyor belt. Specifically, a support rod 6 is provided on the conveyor belt upstream of the detection mechanism, and the infrared sensor 5 is mounted on the support rod 6. Here, the support rod 6 is vertically arranged, and the bottom of the support rod 6 is fixed to the upper surface of the base 1. The infrared sensor 5 is mounted on the side of the support rod 6 facing the belt body 3, so that the infrared sensor 5 faces the upper area of ​​the belt body 3 to detect the height of the products transported on the belt body 3.

[0033] The detection mechanism includes a first motor 7, a lead screw mechanism, and an ultrasonic generator 11. The ultrasonic generator 11 is vertically slidably mounted above the conveyor belt. The first motor 7 is connected to the lead screw mechanism, and the lead screw mechanism is connected to the ultrasonic generator 11.

[0034] The detection mechanism further includes a frame 14 and a mounting plate 10. The frame 14 is approximately a U-shaped frame, with both ends fixed to the upper sides of the base 1, and spans the conveyor belt. A sliding hole 15 is provided on one side of the frame 14. The mounting plate 10 is positioned above the conveyor belt, and the ultrasonic generator 11 is mounted on the bottom of the mounting plate 10. The lead screw mechanism includes a lead screw 8 and a slider 9. One end of the mounting plate 10 is connected to the slider 9, which passes through the sliding hole 15 and can slide vertically. The lead screw 8 is vertically positioned outside the sliding hole 15, passes through the slider 9, and is threadedly connected to the sliding screw 8. A sliding plate 13 is provided at one end of the slider 9, located outside the sliding hole 15 and threadedly connected to the lead screw 8.

[0035] The first motor 7 is connected to one end of the lead screw 8. The lead screw 8 is vertically positioned, and the first motor 7 is mounted on the frame 14 and connected to the upper end of the lead screw 8, enabling it to drive the lead screw 8 to rotate. To ensure stable rotation of the lead screw 8, a bearing seat 16 is provided on the outer side of the conveyor belt. The bearing seat 16 is mounted on the outer side of the upper part of the base 1, and a bearing is installed inside the bearing seat 16. The lower end of the lead screw 8 is connected to the bearing.

[0036] The first motor 7 drives the lead screw 8 to rotate, which in turn causes the slider 9 to slide vertically along the sliding hole 15. The slider 9 then causes the mounting plate 10 to move vertically, thereby causing the ultrasonic generator 11 to move vertically. The first motor 7 is typically a servo motor. By controlling the rotation angle of the first motor 7, the rotation angle of the lead screw 8 can be accurately controlled, thus controlling the vertical movement distance of the slider 9. This allows for precise adjustment of the height of the mounting plate 10, and consequently, the height of the ultrasonic generator 11.

[0037] In some embodiments, sliding holes 15 are provided on opposite sides of the frame 14, the sliding holes 15 are vertically arranged, and the two sliding holes 15 are symmetrical. Slider 9 is provided at both ends of the mounting plate 10, and the two slider 9 can slide vertically through the two sliding holes 15 respectively, so that the two ends of the mounting plate 10 can stably slide vertically along the two sliding holes 15 via the two slider 9.

[0038] In some embodiments, the detection mechanism further includes a guide rod 17, which is vertically arranged and slidably passes through the upper part of the frame 14, and the lower end of the guide rod 17 is connected to the mounting plate 10. When the slider 9 drives the mounting plate 10 to move downward, under the guidance of the guide rod 17, the mounting plate 10 can only move in the vertical direction, thereby ensuring that the ultrasonic generator 11 moves in the vertical direction.

[0039] As will be understood by those skilled in the art, the height of the ultrasonic generator 11 is generally adjusted by controlling the rotation of the first motor 7 via an industrial control computer 12. In this embodiment, the industrial control computer 12 is connected to both the infrared sensor 5 and the first motor 7. The bottom of the industrial control computer 12 is mounted on the upper part of the base 1 via a support pole. The industrial control computer 12 obtains the height of the items on the conveyor belt detected by the infrared sensor 5, and controls the first motor 7 to drive the lead screw mechanism to vertically slide the ultrasonic generator 11 to the desired height based on the height of the items on the conveyor belt. The desired height detected by the ultrasonic generator 11 is determined according to the type of items being transported on the conveyor belt.

[0040] To ensure accurate alignment of the ultrasonic generator 11 with the items transported on the conveyor belt, this invention provides an ultrasonic testing device capable of detecting crops at different heights. The device further includes two guide plates 18, each positioned on one side of the conveyor belt. The two guide plates 18 are symmetrically arranged and approximately right-angled trapezoids. They are positioned parallel to the belt body 3 above the belt. The longer base of each guide plate 18 is fixedly connected to the inner side of the base 1, while the shorter base extends inward. This creates a gradually decreasing width channel along the direction of belt movement, guiding the items on the conveyor belt so that they pass beneath the ultrasonic generator 11. Furthermore, the ultrasonic generator 11 can be positioned on the vertical midline of the conveyor belt for better alignment with the items being tested.

[0041] like Figure 5 As shown, in some embodiments, the base 1 is provided with a tool box 19 inside, through which maintenance tools are stored, which facilitates the maintenance of the ultrasonic testing device that can detect crops at different heights.

[0042] This invention discloses an ultrasonic testing device for detecting crops of different heights. When testing agricultural products, the product is placed on the conveyor belt 3. The conveyor belt, once activated, carries the product past the infrared sensor 5 and the ultrasonic generator 11. As the product passes the infrared sensor 5, the sensor detects it and measures its height. This height determines the required height for the ultrasonic generator 11 to detect the product, which in turn controls the rotation of the first motor 7, accurately controlling the rotation angle of the lead screw 8 and the vertical movement distance of the slider 9. This, in turn, accurately controls the upward or downward movement of the mounting plate 10, moving the ultrasonic generator 11 to the required height for detection, thus enabling accurate detection of agricultural products of different heights.
