[0030] Please refer to Figure 1-4 An embodiment of the present invention provides an ultrasonic agricultural detection device, including a conveyor belt, an infrared sensor 5, a detection mechanism and a controller 12.

[0031] The conveyor belt is arranged horizontally and is used to continuously convey the product 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 is a U-shaped frame structure, and the two rotating rollers 2 are rotatably installed at the two ends of the upper part of the base 1, and the two rotating rollers 2 are arranged in parallel and located on the same horizontal plane. The belt body 3 is sleeved on the two rotating rollers 2, and the belt body 3 and the two rotating rollers 2 form a synchronous belt for stable transmission. The second motor 4 is installed on one side of the base 1 and the output end is connected to one end of the rotating roller 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 arranged 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 arranged on the conveyor belt upstream of the detection mechanism, and the infrared sensor 5 is installed on the support rod 6. Here, the support rod 6 is arranged vertically, and the bottom of the support rod 6 is fixed to the upper surface of the base 1. The infrared sensor 5 is installed 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 screw mechanism and an ultrasonic generator 11 . The ultrasonic generator 11 is vertically slidably disposed above the conveyor belt. The first motor 7 is connected to the screw mechanism, and the 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. The two ends of the frame 14 are fixed to the two sides of the upper part of the base 1, and the frame 14 spans the conveyor belt. A sliding hole 15 is provided on one side of the frame 14. The mounting plate 10 is arranged above the conveyor belt. The ultrasonic generator 11 is installed at the bottom of the mounting plate 10. The screw mechanism includes a screw rod 8 and a slider 9. One end of the mounting plate 10 is connected to the slider 9. The slider 9 passes through the sliding hole 15 and can slide vertically. The screw rod 8 is vertically arranged on the outside of the sliding hole 15. The screw rod 8 passes through the slider 9 and is connected to the sliding thread. Here, one end of the slider 9 is provided with a sliding plate 13, which is located on the outside of the sliding hole 15 and is threadedly connected to the screw rod 8.

[0035] The first motor 7 is connected to one end of the screw rod 8. Here, the screw rod 8 is arranged vertically, and the first motor 7 is mounted on the frame 14 and connected to the upper end of the screw rod 8, and can drive the screw rod 8 to rotate. In order to make the screw rod 8 rotate stably, a bearing seat 16 is provided on the outer side of the conveyor belt, and the bearing seat 16 is installed on the outer side of the upper part of the base 1. A bearing is provided in the bearing seat 16, and the lower end of the screw rod 8 is connected to the bearing.

[0036] The first motor 7 drives the screw rod 8 to rotate, which can drive the slider 9 to slide vertically along the sliding hole 15, and the slider 9 drives the mounting plate 10 to move vertically, thereby driving the ultrasonic generator 11 to move vertically. The first motor 7 is generally a servo motor. By controlling the rotation angle of the first motor 7, the rotation angle of the screw rod 8 can be accurately controlled to control the vertical movement distance of the slider 9, thereby accurately adjusting the height of the mounting plate 10, that is, accurately adjusting the height of the ultrasonic generator 11.

[0037] In some embodiments, two opposite sides of the frame 14 are provided with sliding holes 15, the sliding holes 15 are vertically arranged, and the two sliding holes 15 are symmetrical. Both ends of the mounting plate 10 are provided with sliders 9, and the two sliders 9 can vertically slide 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 through the two sliders 9.

[0038] In some embodiments, the detection mechanism further includes a guide rod 17, which is vertically arranged and slidably penetrates 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] The controller 12 is connected to the infrared sensor 5 and the first motor 7 respectively. Specifically, the controller 12 selects an industrial computer, and the bottom of the industrial computer is installed on the upper part of the base 1 through a vertical rod. The controller 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 drive the ultrasonic generator 11 to slide vertically to a required height according to the height of the items on the conveyor belt. The required height detected by the ultrasonic generator 11 is determined according to the type of items transported on the conveyor belt.

[0040] In order to make the ultrasonic generator 11 accurately align with the items transported on the conveyor belt for detection, an ultrasonic agricultural detection device of the present invention also includes two guide plates 18, and the two guide plates 18 are respectively arranged on both sides of the conveyor belt. The two guide plates 18 are symmetrically arranged, and the guide plates 18 are approximately right-angled trapezoids. The guide edges are arranged parallel to the top of the belt body 3. The longer bottom edge of the guide plate 18 is fixedly connected to the inner side of the base 1, and the shorter bottom edge of the guide plate 18 extends inward, so that the two guide plates 18 form an item channel with a gradually decreasing width along the moving direction of the belt body 3, so as to guide the items on the conveyor belt so that the items pass under the ultrasonic generator 11. In addition, the ultrasonic generator 11 can also be arranged on the vertical center plane of the conveyor belt so that the ultrasonic generator 11 can better align with the detected items.

[0041] When an ultrasonic agricultural detection device of the present invention detects agricultural products, the agricultural products to be detected are placed on the belt body 3 of the conveyor belt, and the conveyor belt is started to drive the agricultural products to be detected to pass through the infrared sensor 5 and the ultrasonic generator 11 in sequence. When the agricultural products to be detected pass through the infrared sensor 5, the infrared sensor 5 senses the agricultural products to be detected and measures the height of the agricultural products to be detected. After that, the controller 12 obtains the height of the agricultural products to be detected from the infrared sensor 5, and determines the height required for the ultrasonic generator 11 to detect the agricultural products to be detected according to the height of the agricultural products to be detected, and then controls the rotation of the first motor 7, accurately controls the rotation angle of the screw rod 8, and controls the vertical movement distance of the slider 9, so as to accurately control the upward or downward movement of the mounting plate 10, drive the ultrasonic generator 11 to move to the height required for the detection of the agricultural products to be detected, and then realize accurate detection of agricultural products of different heights.
