Description

Technical Field

[0001] This invention relates to the field of agricultural product processing, and more particularly to a transport device for agricultural product processing. Background Technology

[0002] With the continuous development of automated processing technology, in order to solve the problems of low efficiency, high labor intensity and inconsistent screening standards of traditional manual screening, the existing agricultural product processing process usually integrates automated detection and screening devices in the material conveying process. Visual sensors collect the appearance image information of the materials and cooperate with the screening mechanism to realize the automated screening of materials, and promptly pick out unqualified materials such as damaged appearance, unqualified size, and abnormal color, thereby effectively improving production efficiency and product quality. This automated screening mode based on visual detection has been widely used in various agricultural product processing production lines.

[0003] However, after the roasting and drying processes, Gastrodia elata is easily affected by various factors such as processing parameters and the quality of the raw materials, resulting in internal corrosion and hollowness. At the same time, differences in the quality of the raw materials or fungal contamination during processing may also lead to internal corrosion and damage, forming hollow defects. These hollow Gastrodia elata are usually characterized as "hollow and wrinkled, of inferior quality", which seriously affects their medicinal and commercial value.

[0004] Existing visual sensor detection methods can only identify and judge the surface features of Gastrodia elata, such as its appearance, color, and size. They cannot penetrate the epidermis to detect its internal structure. For defects like Gastrodia elata that are hollow inside but have no obvious abnormalities on the outside, visual detectors have difficulty effectively identifying and distinguishing them. Some infrared spectroscopy and hyperspectral imaging technologies are either too expensive and have complex data processing, or have limited penetration depth, making them unsuitable for the real-time detection needs during the processing and transportation of Gastrodia elata. As a result, a large number of hollow, substandard products cannot be picked out in time during the processing and transportation of Gastrodia elata. This not only reduces the overall quality of the final product, affecting its market competitiveness and medicinal effects, but may also lead to raw material waste and increased processing costs. Summary of the Invention

[0005] To overcome the drawback that Gastrodia elata may develop hollowness due to internal corrosion after frying and drying, and that existing technologies cannot detect this internal hollowness defect using only visual detectors, this invention provides a transportation device for agricultural product processing.

[0006] The technical implementation of the present invention is as follows: a transportation device for agricultural product processing includes a conveyor frame; a fixed block connected to the conveyor frame; a feed inlet is provided on the upper side of the fixed block; a fixed plate is slidably connected to the feed inlet; a through groove is opened in the fixed plate; a receiving block is slidably connected in the through groove; a connecting pipe is fixedly connected to the lower side of the fixed block; a telescopic pipe is fixedly connected between the connecting pipe and the fixed plate; a driving component for moving the fixed plate and the receiving block is connected inside the fixed block; a pressing component for pressing materials is connected on the conveyor frame; a waste bin is fixedly connected to the lower side of the conveyor frame; an air pump is provided inside the waste bin, and a suction pipe is connected to the suction port of the air pump; the suction pipe is connected to the connecting pipe.

[0007] Optionally, the drive assembly includes a plurality of first electric push rods connected to a fixed block; each first electric push rod has a slider fixedly connected to its output end; each slider is connected to a fixed plate; a second electric push rod is fixedly connected to the fixed block, and a connector is fixedly connected to the output end of the second electric push rod, the connector being rotatably connected to the receiving block.

[0008] Optionally, the extrusion assembly includes a fixed frame connected to the conveyor frame; a third electric push rod is fixedly connected to the fixed frame; a first extrusion block is fixedly connected to the output end of the third electric push rod; the first extrusion block is located directly above the feed inlet; and a vision detector is fixedly connected to the lower side of the first extrusion block.

[0009] Optionally, it also includes a first collection box, a second collection box, and a motor; a weighing device is provided on the receiving block; the first collection box and the second collection box are placed below the conveyor frame; the first collection box is located on the left side of the fixed block, and the second collection box is located on the right side of the fixed block; a motor is fixedly connected to each slider, and the output end of the motor is fixedly connected to the fixed plate; each slider is rotatably connected to the fixed plate.

[0010] Optionally, the upper surface of the receiving block is concave.

[0011] Optionally, guide grooves are provided on all four sides of the first extrusion block.

[0012] Optionally, it also includes a sliding rod, a spring, and a second extrusion block; a plurality of sliding rods are slidably connected to the lower side of the first extrusion block; a spring is fixedly connected between each sliding rod and the first extrusion block; and a second extrusion block is fixedly connected to the lower side of each sliding rod.

[0013] Optionally, the second extrusion block is made of rubber.

[0014] Optionally, a sealing cover attached to the conveyor frame is also included.

[0015] Optionally, it also includes a sterilization lamp connected within a sealed enclosure.

[0016] The present invention has the following advantages: by squeezing the Gastrodia elata on the receiving block with the first squeezing block, the hollow Gastrodia elata is crushed, and then the imaging detection is performed by the visual detector, thereby solving the problem that the existing technology is difficult to detect such internal hollow defects by visual detector alone.

[0017] The second electric push rod carries the charred, damaged, and hollow Gastrodia elata from the receiving block to the suction pipe, and then the charred, damaged, and hollow Gastrodia elata are sucked into the waste bin for collection through the suction pipe.

[0018] The weight of Gastrodia elata is detected by a weighing device inside the receiving block. The motor drives the fixed plate and the receiving block to rotate, and the high-quality Gastrodia elata weighing between 100 grams is sent into the first collection box, while the low-quality Gastrodia elata weighing less than 100 grams is sent into the second collection box. The Gastrodia elata of different qualities are then screened after detection.

[0019] As the first extrusion block moves downward, several dispersed sliding rods apply localized extrusion to the gastrodia elata, thus overcoming the problem that the first extrusion block only contacts the intact protruding areas of the gastrodia elata and cannot act on the hollow areas, resulting in the inability to screen out locally corroded and damaged gastrodia elata.

[0030] It also includes a fixed block 2, a waste bin 6, a fixed plate 101, a receiving block 102, a telescopic pipe 106, a connecting pipe 107, a suction pipe 109, a drive assembly, and an extrusion assembly; the fixed block 2 is fixedly connected to the conveyor frame 1; a feed inlet 2001 is provided on the upper side of the fixed block 2, and the feed inlet 2001 is constricted; the fixed plate 101 is slidably connected to the feed inlet 2001; a through groove 10101 is opened in the fixed plate 101; the receiving block 102 is slidably connected in the through groove 10101; a connecting pipe 107 is fixedly connected to the lower side of the fixed block 2; a telescopic pipe 106 is fixedly connected between the connecting pipe 107 and the fixed plate 101; a drive assembly is connected inside the fixed block 2; an extrusion assembly is connected to the conveyor frame 1; a waste bin 6 is fixedly connected to the lower side of the conveyor frame 1; an air pump is provided inside the waste bin 6, and the suction port of the air pump is connected to a suction pipe 109; the suction pipe 109 is connected to the connecting pipe 107.

[0031] The drive assembly includes a first electric push rod 103, a slider 104, and a second electric push rod 108; two first electric push rods 103 are fixedly connected to the fixing block 2; a slider 104 is fixedly connected to the output end of each first electric push rod 103; each slider 104 is connected to the fixing plate 101; a second electric push rod 108 is fixedly connected to the fixing block 2, and a connector 10801 is fixedly connected to the output end of the second electric push rod 108, which is rotatably connected to the receiving block 102.

[0032] The extrusion assembly includes a fixed frame 3, a first extrusion block 201, a third electric push rod 202, and a vision detector 206; the fixed frame 3 is fixedly connected to the conveyor frame 1; the third electric push rod 202 is fixedly connected to the fixed frame 3; the first extrusion block 201 is fixedly connected to the output end of the third electric push rod 202; the first extrusion block 201 is located directly above the feed inlet 2001; the vision detector 206 is fixedly connected to the lower side of the first extrusion block 201.

[0033] It also includes a first collection box 4, a second collection box 5, and a motor 105; a weighing device is provided on the receiving block 102; the first collection box 4 and the second collection box 5 are placed below the conveyor frame 1; the first collection box 4 is located on the left side of the fixed block 2, and the second collection box 5 is located on the right side of the fixed block 2; a motor 105 is fixedly connected to each slider 104, and the output end of the motor 105 is fixedly connected to the fixed plate 101; each slider 104 is rotatably connected to the fixed plate 101.

[0034] The upper surface of the receiving block 102 is concave.

[0035] The first extrusion block 201 has guide grooves 20101 on all four sides, and each guide groove 20101 is inclined toward the fixed plate 101.

[0036] Working principle of Example 1: First, the stir-fried and dried Gastrodia elata is conveyed to the feed inlet 2001 through the conveyor frame 1. Then, the Gastrodia elata will roll into the receiving block 102 in the middle of the fixed plate 101. During the process of the Gastrodia elata rolling into the receiving block 102, the appearance of the Gastrodia elata is captured by the vision detector 206. Then, the captured image is detected to check whether there is any scorching or damage on the appearance of the Gastrodia elata.

[0037] However, considering that in actual production, after stir-frying and drying, Gastrodia elata may develop a hollow state due to internal corrosion, the appearance of such hollow Gastrodia elata is often intact, making it difficult to distinguish from normal Gastrodia elata. The visual detector 206 alone cannot detect this internal hollow defect. Therefore, after capturing an image of the Gastrodia elata, the third electric push rod 202 is activated, causing the first extrusion block 201 to move downwards, thereby extruding the Gastrodia elata on the receiving block 102. At this point, the hollow Gastrodia elata will break after being extruded by the first extrusion block 201, while the intact Gastrodia elata, after stir-frying and drying, has a harder texture and can remain intact. After the first extrusion block 201 extrudes the Gastrodia elata, the visual detector 206 performs imaging detection to check whether the Gastrodia elata has broken. This solves the problem of the existing technology's inability to detect this internal hollow defect using only the conventional visual detector 206 without the need for expensive equipment such as infrared spectroscopy or hyperspectral imaging technology, greatly reducing production costs.

[0038] Furthermore, upon detecting charred, damaged, or hollow Gastrodia elata, the second electric push rod 108 moves the receiving block 102 downwards, thereby bringing the charred, damaged, and hollow Gastrodia elata to the suction pipe 109. Then, the air pump in the waste bin 6 is activated, causing the suction pipe 109 to generate suction force, drawing the charred, damaged, and hollow Gastrodia elata from the receiving block 102 into the waste bin 6 for recycling. Simultaneously, considering that when the first extrusion block 201 extrudes the hollow Gastrodia elata, the resulting fragments will fly out of the receiving block 102 and splash onto the fixing plate 101, preventing the receiving block 102 from carrying these fragments to the suction pipe 109, therefore, when the suction pipe 109 is suctioning, if... Figure 5 and Figure 6 As shown: At this time, the first extrusion block 201 is in a downward pressing state. The first extrusion block 201 is in contact with the inner wall of the feed inlet 2001, so that a cavity is formed at the feed inlet 2001. When the suction pipe 109 is suctioning, a negative pressure will be formed at the feed inlet 2001, which will draw in outside air into the feed inlet 2001. The outside air enters the telescopic pipe 106 along the guide groove 20101 that is inclined towards the fixed plate 101, which will bring the debris splashed on the fixed plate 101 into the telescopic pipe 106. Finally, it is sucked into the waste bin 6 through the suction pipe 109, thereby realizing the suction and cleaning of the debris splashed on the fixed plate 101. This prevents the debris splashed on the fixed plate 101 from adhering to the surface of the Gastrodia elata after contact with it, which would affect the quality of the Gastrodia elata. This effectively removes waste Gastrodia elata that is charred, damaged, or hollow inside.

[0039] Furthermore, the weight of Gastrodia elata can reflect its growth status and nutritional reserves to some extent. Generally, mature, plump, and disease-free high-quality Gastrodia elata will have a relatively large weight under the same growth cycle and environment because its internal tissue is full and there are no defects such as hollowness or decay. It is usually in the range of 20-50 grams. Poorly developed or early decayed low-quality Gastrodia elata will be significantly lighter in weight due to its incomplete internal structure. To improve the detection and screening effect of Gastrodia elata, high-quality Gastrodia elata weighing between 20-50 grams need to be sorted out separately. Therefore, when the first extrusion block 201 extrudes the Gastrodia elata, and the vision detector 206 detects that the Gastrodia elata is intact, the weight of the Gastrodia elata is detected by the weighing device inside the receiving block 102. To avoid inaccurate measurement results caused by contact between the Gastrodia elata inside the receiving block 102 and the fixing plate 101, the first extrusion block 201 is moved upward and reset during weighing by the third electric push rod 202. Then, the second electric push rod 108 is activated to push the receiving block 102 upward, thereby moving the Gastrodia elata on the receiving block 102 upward, so that the Gastrodia elata and the fixing plate 101 are separated from each other, avoiding contact interference that affects the weighing accuracy. After weighing is completed, the slider 104, the motor 105 and the fixing plate 101 are moved downward by the first electric push rod 103, while the second electric push rod 108 pushes the receiving block 102 upward, thereby moving the Gastrodia elata on the receiving block 102 upward, so that the Gastrodia elata and the fixing plate 101 are separated from each other, avoiding contact interference that affects the weighing accuracy. The push rod 108 synchronously drives the receiving block 102 to move downwards, moving the fixing plate 101 and the receiving block 102 directly above the first collection box 4 and the second collection box 5. Then, based on a front-to-back view, when the weighing result is in the 20-50 gram high-quality range, the motor 105 is started, driving the fixing plate 101 to rotate counterclockwise by 45°. The fixing plate 101 synchronously drives the receiving block 102 to rotate counterclockwise by 45°, and the high-quality Gastrodia elata on the receiving block 102 rolls down the inclined fixing plate 101 and the receiving block 102 into the first collection box 4. When the weighing result is below 20 grams and is considered low-quality Gastrodia elata, the motor 105 is started, driving the fixing plate 101 to rotate clockwise by 45°. The fixing plate 101 synchronously drives the receiving block 102 to rotate clockwise by 45°, and the low-quality Gastrodia elata on the receiving block 102 rolls down the inclined fixing plate 101 and the receiving block 102 into the second collection box 5.

[0040] Example 2: Based on Example 1, as follows Figure 1 , Figure 6 and 7 As shown, it also includes a sliding rod 203, a spring 204, and a second pressing block 205; a plurality of sliding rods 203 are slidably connected to the lower side of the first pressing block 201; a spring 204 is fixedly connected between each sliding rod 203 and the first pressing block 201; and a second pressing block 205 is fixedly connected to the lower side of each sliding rod 203.

[0041] The second extrusion block 205 is made of rubber.

[0042] It also includes a sealing cover 207; the sealing cover 207 is fixedly attached to the conveyor frame 1.

[0043] It also includes a sterilization lamp 208; several sterilization lamps 208 are fixedly attached to the lower side of the sealing cover 207.

[0044] Working principle of Example 2: When the Gastrodia elata is compressed by the first compression block 201, it is considered that when the Gastrodia elata has localized corrosion damage, after frying and drying, only a local area of ​​the Gastrodia elata is hollow. At this time, the hollow area will sink inward after drying, while the uncorroded area will bulge outward. Therefore, when the Gastrodia elata is compressed in the first compression block 201, the first compression block 201 will only contact the outward bulging uncorroded area and cannot compress the hollow area. As a result, the damaged Gastrodia elata remains intact after compression, and the subsequent visual detector 206 will also be unable to detect this type of locally corroded Gastrodia elata. Therefore, during the downward movement of the first pressing block 201, several dispersed sliding rods 203 will preferentially contact the Gastrodia elata. At this time, the smaller sliding rods 203 apply pressure to the hollow area of ​​the Gastrodia elata, thereby overcoming the defect that the first pressing block 201 only contacts the protruding intact area and cannot act on the hollow area. It should be noted that when the sliding rod 203 contacts the intact Gastrodia elata and the uncorroded and undamaged area of ​​the Gastrodia elata, the sliding rod 203 moves upward under the reverse pressure of the Gastrodia elata, pulling the spring 204 upward. The spring 204 is stretched, thereby avoiding excessive pressure from the sliding rod 203 on the Gastrodia elata, which would cause damage to the Gastrodia elata.

[0045] Furthermore, such as Figure 1 As shown: During the transportation of Gastrodia elata, the Gastrodia elata inside the conveyor frame 1 is covered by a sealing cover 207 to prevent the Gastrodia elata from being contaminated by dust and impurities in the air during transportation, which would affect the quality of the Gastrodia elata.

[0046] Furthermore, such as Figure 7 As shown: The gastrodia elata in the conveyor rack 1 is sterilized with ultraviolet light by sterilization lamp 208 to ensure the quality of gastrodia elata and improve its quality and value.

[0047] Furthermore, the second extrusion block 205 is made of rubber to prevent the second extrusion block 205 from scratching the medicinal materials during the extrusion process, which would damage the medicinal materials and affect their quality.
