Description

Technical Field

[0001] This utility model relates to the field of fruit firmness testing technology, and more specifically, to a fruit firmness testing instrument. Background Technology

[0002] Fruit is an edible plant fruit that not only contains rich vitamins but also promotes digestion. During the fruit cultivation stage, it is necessary to randomly select some fruits to test their firmness to determine their ripeness. This is crucial for the proper management of harvesting, including the cultivation of superior varieties, harvesting time, processing time, harvesting and storage, and export transportation. Currently, most of the existing testing methods use fruit firmness testers for measurement.

[0003] Existing fruit hardness testers require inserting the testing head into the fruit to measure its hardness. Because the fruit surface is relatively smooth, the fruit needs to be fixed during testing. The typical operation method involves first fixing the fruit on the testing table and then operating the testing instrument. During the feeding and unloading of the fruit, the testing instrument is usually in a stopped state, resulting in low efficiency in measuring fruit hardness.

[0004] In light of this, we propose a fruit firmness tester. Utility Model Content

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

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A fruit hardness tester includes a fixed base 1, a mounting rod 2 rotatably mounted on the upper side of the fixed base 1, a testing platform 3 fixedly mounted on the upper end of the mounting rod 2, multiple sets of positioning frames 4 fixedly mounted on the upper side of the testing platform 3, positioning discs 5 movably mounted inside each of the multiple sets of positioning frames 4, and a movable rod 6 fixedly mounted on the outer side of the positioning discs 5. The movable rod 6 movably passes through the positioning frames 4 and extends to the outer side, and a handle 7 is fixedly mounted on the outer end of the movable rod 6 located outside the positioning frames 4. A first spring 8 is sleeved on the outer side of the movable rod 6, with one end of the first spring 8 connected to the handle 7 and the other end of the first spring 8 connected to the positioning frame 4. The mounting rod 2 moves through the fixed base 1 and extends to the lower side. The lower end of the mounting rod 2 is fixedly provided with an adjustment plate 9 on the lower part of the fixed base 1. The lower side of the fixed base 1 is provided with a positioning mechanism 10 that docks with the adjustment plate 9. The first spring 8 does not deform in the initial state. When fixing the fruit, the movable rod 7 and the positioning plate 5 are moved by moving the handle 7. At this time, the first spring 8 deforms. Then the fruit is placed into the positioning frame 4. Subsequently, the elastic potential energy of the first spring 8 is released, which can drive the positioning plate 5 to move quickly and clamp the fruit, improving the convenience of fixing the fruit.

[0029] Specifically, an electric push rod 11 is provided on the upper side of the fixed base 1. One end of the electric push rod 11 is connected to the fixed base 1, and the other end of the electric push rod 11 is provided with a mounting plate 12. A detector 13 is fixedly installed on the upper side of the mounting plate 12. The detector 13 passes through the mounting plate 12 and extends to the lower side. A detection head 14 is fixedly installed on the lower side of the detector 13, located on the lower side of the mounting plate 12. By opening the electric push rod 11, the detector 13 and the detection head 14 can be easily moved downward, so that the detection head 14 can be easily inserted into the fruit for testing. The specific hardness parameters of the fruit can be obtained from the values ​​on the detector 13.

[0030] Furthermore, the positioning mechanism 10 includes a fixing block 15 fixedly disposed on the lower side of the fixing base 1. A connecting rod 16 is movably inserted into the inner side of the fixing block 15. The connecting rod 16 movably passes through the fixing block 15 and extends to the outer side. A chuck 17 is fixedly disposed on the outer end of the connecting rod 16 located on the outer side of the fixing block 15. Multiple sets of slots are opened on the inner side of the chuck 17. Multiple sets of mating slots are fixedly disposed on the outer side of the adjusting plate 9. A second spring 18 is disposed on the inner side of the fixing block 15. One end of the second spring 18 is connected to the fixing block 15, and the other end of the second spring 18 is connected to the fixing block 15. The end is connected to the connecting rod 16. The second spring 18 does not deform in the initial state. When the detection table 3 rotates, the connecting rod 16 is moved first to drive the chuck 17 to separate from the adjustment plate 9. When the connecting rod 16 moves, it squeezes the second spring 18 inside the fixed block 15, causing the second spring 18 to deform. After the detection table 3 is adjusted, the connecting rod 16 is released. At this time, the elastic potential energy of the second spring 18 is released, which can drive the chuck 17 to quickly fit into the adjustment plate 9, thereby improving the convenience of adjustment and the stability of use of the detection table 3.

[0031] It is worth noting that an anti-slip pad 19 is fixedly installed on the outside of the positioning plate 5. The anti-slip pad 19 can improve the friction of the positioning plate 5, making the fruit more secure.

[0032] It is worth noting that a handle 20 is fixedly installed on the lower side of the adjustment disc 9. The handle 20 allows the adjustment disc 9 to be rotated easily, improving the ease of operation.

[0033] In addition, a push block 21 is fixedly provided on the outside of the connecting rod 16. By providing the push block 21, the connecting rod 16 can be moved easily, thereby improving the ease of moving the chuck 7.

[0034] It must be said that an arrow 22 is fixedly set on the outside of the positioning frame 4, and a calibration mark 23 for aligning with the arrow 22 is fixedly set on the upper side of the fixing seat 1. By setting the calibration mark 23, the arrow 22 can be calibrated, so that the detection table 3 can be rotated to a suitable position, and the detection head 14 can be accurately inserted into the fruit for detection.

[0035] Working principle: First, pull the handle 7 outward to move the movable rod 6 and the positioning plate 5. When the handle 7 moves, it stretches the first spring 8, causing it to deform. Then, place the fruit to be tested into the positioning frame 4. Next, release the handle 7. The rebound force of the first spring 8 will move the positioning plate 5 to fix the fruit. Then, turn on the electric push rod 11 through the external power supply to move the mounting plate 12 and the detector 13 downward. The detection head 14 is inserted into the fruit for detection. At the same time, while the fruit is being tested, the fruit to be tested can be placed into other empty positioning frames 4. At the same time, the fruit that has been tested in the positioning frame 4 can also be taken out, thereby effectively improving the efficiency of fruit testing.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
