Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato skin abrasion resistance detection, in particular to a sweet potato skin abrasion resistance detection device. Background Technique

[0002] Sweet potatoes are recognized as "healthy foods" and "space foods" in the world. The planting area and total output of sweet potatoes in China have always ranked first in the world. With the improvement of people's living standards, the "life-saving sweet potatoes" in history are transforming into the current "healthy sweet potatoes". Therefore, the market demand ratio of fresh sweet potatoes is increasing year by year, and the requirements for the appearance quality (sweet potato shape and skin integrity) of fresh sweet potatoes are also increasing year by year. How to maintain the integrity of the sweet potato skin has become an industrial problem that cannot be ignored. At present, the main reasons for the damage of fresh sweet potato skin are as follows. One is the damage during mechanical harvesting. The harvesting machine directly rubs and collides with the sweet potatoes, resulting in the damage of the sweet potato skin. At the same time, the rubbing between sweet potatoes during the manual picking and packing process causes the wear of the sweet potato skin; the second is the damage during the transportation of sweet potatoes. Due to the bumps during transportation or the extrusion between sweet potatoes when getting on and off the vehicle, the sweet potato skin is damaged; the third is the damage during the cleaning process of sweet potatoes. In order to improve the commerciality, sweet potatoes need to be cleaned, and both brush cleaning and bubble cleaning will cause the sweet potatoes to rub against each other, indirectly or directly causing damage to the sweet potato skin.

[0003] Improving the abrasion resistance of the sweet potato skin is of great significance for improving the efficiency of mechanized operations, the disease resistance of sweet potatoes, and the storage resistance of sweet potatoes. First of all, improving the abrasion resistance of sweet potato skin can improve the harvesting efficiency, improve the efficiency of mechanical and manual harvesting, and reduce the labor cost of harvesting; secondly, it can improve the storage resistance and disease resistance of sweet potatoes. The sweet potato skin is an important physical defense of sweet potatoes, which can effectively resist the invasion of pests and diseases and reduce water loss; finally, it can improve the appearance quality of sweet potatoes. Mechanized cleaning and grading are important means to improve the "appearance value" of sweet potatoes in the future. In the market, sweet potatoes are graded and sold according to the degree of epidermal wear. Sweet potatoes with intact epidermis are often sold at high prices as high-quality products, while those with severely worn epidermis cannot even be sold.

[0004] In order to adapt to mechanized production and transportation and reduce the damage of sweet potato skin, the United States has carried out a series of studies on the identification method and variety selection of sweet potato skin abrasion resistance, including the establishment of a sweet potato skin abrasion resistance detection platform and the detection of related genes that may be involved in sweet potato skin abrasion resistance through ACPs (primer annealing control technology). However, relevant research has not been carried out in China. Therefore, we have developed a set of devices and methods that can quickly identify the abrasion resistance of sweet potato skin, which can provide technical support for the screening of sweet potato varieties with abrasion resistance and the research on sweet potato skin abrasion resistance in the future. Content of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a sweet potato skin abrasion resistance detection device;

[0007] 1. To establish an evaluation system for the abrasion resistance of sweet potato skins. According to the technology of the present utility model, the abrasion resistance of sweet potatoes is visualized and dataized;

[0008] 2. To quickly identify and screen sweet potato varieties with high abrasion resistance. Based on the portability of the technology of the present utility model, the abrasion resistance of sweet potato skins can be quickly identified in the field, providing technical support for the excavation of genes related to sweet potato skin abrasion resistance;

[0009] 3. To determine the time for high-temperature healing of sweet potatoes. After being harvested, sweet potatoes need to be heat-treated, usually maintained at a high temperature of 35°C for a certain period of time, which helps to promote the metabolism of the outer skin of sweet potatoes, accelerate the healing and repair of injuries, and reduce bacterial and fungal infections, thereby extending the storage time of sweet potatoes and reducing rot. Through testing, during the high-temperature healing process, the abrasion resistance of sweet potato skins will increase. The technology of the present utility model can accurately determine the time for high-temperature healing, avoiding too short a high-temperature healing time, resulting in the skin not achieving the effect of high-temperature healing; or too long a time at high temperature, thus affecting the quality of sweet potatoes.

There is no need to transport the samples back to the laboratory, which greatly shortens the detection cycle, enabling farmers to quickly determine whether the peel strength of the sweet potatoes meets the requirements of mechanized harvesting. This can not only reduce the loss of sweet potatoes caused by peel damage but also improve the efficiency and quality of mechanized harvesting, providing strong guarantee for the subsequent processing and storage of sweet potatoes.

[0020] 2. Through accurate torque measurement and abrasion resistance evaluation of the sweet potato peel, the technology of the present utility model can accurately detect whether the sweet potatoes after high-temperature healing meet the expected healing standards. This function helps farmers and agricultural technicians scientifically and reasonably control the time of high-temperature healing, ensuring that the sweet potatoes will neither lose nutrients due to too long time nor fail to fully repair the damage due to too short time during the healing process, thereby improving the overall quality and market competitiveness of the sweet potatoes.

[0021] 3. The technology of the present utility model provides strong technical support for the identification and breeding of sweet potato varieties with abrasion resistance. By conducting large-scale and rapid detection of the abrasion resistance of different sweet potato varieties, scientific research personnel can screen out sweet potato varieties with excellent abrasion resistance characteristics, laying a solid foundation for subsequent variety improvement and popularization and application. At the same time, this technology also helps to reveal the genetic mechanism of sweet potato abrasion resistance, providing an important reference for sweet potato molecular breeding.

It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.

[0030] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0031] A sweet potato skin abrasion resistance detection device, including a handle 1, one end of the handle 1 is connected to a machine shell 2, one side of the machine shell 2 is connected to an elastic long rod 3, and one end of the elastic long rod 3 is connected to a ratchet head 4. A Δ button 5 is arranged on the outer surface of one side of the machine shell 2, A button 6, a U button 7, a C button 8 and a display screen 9, and a microprocessor, a torque sensor, a circuit board and a rechargeable battery are arranged inside the casing 2. Connecting shells 811 are fixedly installed on both sides of the bottom end of the handle 1, and a fixing rod 816 is arranged at one end of the connecting shell 811. One end of the fixing rod 816 is respectively connected with a first long rod 911 and a second long rod 916, and a connecting rod 912 is fixedly installed between the first long rod 911 and the second long rod 916. A chute is arranged on the outer surface of one side of the first long rod 911, and two sliding blocks 915 are movably installed in the chute. An elastic strap 914 is connected to one side of the two sliding blocks 915. A limiting plate 913 is fixedly installed on one side of the second long rod 916, and two limiting grooves 917 are arranged on the outer surface of the limiting plate 913.

[0032] Further, a cavity is arranged on the inner wall of the connecting shell 811, and an adjusting rod 812 is movably installed in the cavity. By arranging a cavity on the inner wall of the connecting shell 811 and installing the adjustable adjusting rod 812, the user can adjust the fixing device according to the size or shape of the sweet potato, so that the sweet potato is fixed more tightly, and the accuracy and stability of the test are improved.

[0033] Further, a sleeve 813 is fixedly installed on the moving adjusting rod 812, and a shaft rod 814 is movably installed on the inner wall of the sleeve 813. Connecting plates 815 are fixedly installed at both ends of the shaft rod 814, and a fixing rod 816 is connected to one side of the connecting plate 815. The shaft rod 814 enables the fixing rod 816 to drive the second long rod 916 and the first long rod 911 to rotate and fold, so as to facilitate carrying.

[0034] Further, magnets 711 are fixedly installed at the bottom ends of the first long rod 911 and the second long rod 916. The magnets 711 facilitate the adsorption after the long rods are folded, so as to maintain their stability.

[0035] Further, one end of the first long rod 911 and the second long rod 916 is serrated. The serrated end increases the friction between the long rod and the placement contact surface of the tabletop, making it more stable.

[0036] Further, rubber is wrapped around the bottom end of one end of the first long rod 911 and the second long rod 916. The rubber further increases the stability and protects the contact surface from damage.

[0037] Further, both ends of the limiting plate 913 are arc-shaped, reducing the potential safety hazards that may be brought by sharp corners.

[0038] Working principle: Press the C button 8 to turn on the display screen 9. Long press the U button 7 of the torque wrench, and through the Δ button 5 and The button 6 is adjusted to the "Peak" mode. Press the U button 7 to adjust the unit, and there are 4 units to choose from. It is recommended to use "kg.cm" or "N.m". The maximum value measured by the torque wrench used in the technical solution of the present utility model is "61.18 kg.cm" or "6 N.m", and the minimum value is "3.059 kg.cm" or "0.3 N.m". (Currently, the maximum torque obtained from the detected varieties does not exceed 2 N.m) Select sweet potatoes of the same size for detection (it is recommended that the sample weight is about 150 - 200 g). Insert one of the sweet potatoes parallel into the ratchet head on one side of the machine housing 2, and then use two sets of elastic straps (914) to bypass both sides of the sweet potato. Insert one end of the elastic strap 914 through two sets of limit slots 917 on the outer surface of the limit 913 to fix the sweet potato. Hold another sweet potato in hand and rub it against the fixed sweet potato. When the skin of the sweet potato is damaged, the display screen 9 will display the minimum torque that causes the skin of the sweet potato to be damaged (no reading will be generated if the skin of the sweet potato is not damaged). When the skin of the sweet potato is damaged, a reading will be generated, and this reading represents the torque used when the skin of the sweet potato is damaged. Since the length of the force arm is the same, the torque displayed on the display is proportional to the force that breaks the skin of the sweet potato. When making the friction, the speed cannot be too fast, otherwise it will affect the result.
