Description

Technical Field

[0001] This utility model relates to the field of pear decalyx removal tools, and in particular to an efficient decalyx removal device for improving the shape of pears. Background Technology

[0002] In the cultivation of pear trees, some varieties exhibit the phenomenon of persistent sepals. Persistent sepals refer to the condition where, after the pear tree blossoms, the sepals (part of the calyx) do not fall off but continue to grow on the fruit. These sepals are still visible when the fruit matures, and sometimes even develop into part of the fruit itself. Based on whether the sepals fall off, pears can be divided into "sepal-detached fruit" and "persistent sepal fruit." Sepal-detached fruit has the sepals fall off before the fruit matures, resulting in a concave base, a round and plump shape, and usually a better taste, higher sweetness, and richer flavor. Persistent sepal fruit, on the other hand, has the sepals still attached to the fruit when it matures, causing a bulging base, an irregular shape, a firmer texture, and a milder flavor.

[0003] Fruit growers discovered that removing the calyx from young pears can improve their appearance and internal quality. Calyx removal, also known as "cutting the bottom" or "pinching the calyx," was initially done to prevent pests by cutting off the calyx along with part of the fruit flesh. However, it was unexpectedly discovered that after removing the calyx, the pears became larger, the top became concave, the shoulders swelled, and the flesh became plump, fluffy, crisp, and tender, greatly improving the quality.

[0004] Currently, for pear varieties prone to developing persistent calyxes, the common practice is to "pinch the calyx," usually using a small or modified tool knife. However, current calyx removal tools lack safety considerations. When operators use these tools to remove the calyxes from young pears, they are prone to injuring their fingers, which hinders the efficient and smooth progress of the calyx removal work.

[0005] Therefore, designing a calyx removal device that can both quickly remove the calyx from young pears and protect the operator from injury is of great practical significance for pear varieties that require calyx removal. Summary of the Invention

[0006] To address the deficiencies in the existing technology, this utility model provides an efficient calyx removal device for improving the shape of pears. By setting a protective fan-shaped plate and hinged it to the handle of a tool knife, the fan-shaped plate effectively protects the operator's index finger from injury when the tool knife rotates to cut off the calyx portion, thus solving the problems existing in the background technology.

[0007] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0008] An efficient calyx removal device for improving the shape of pear fruit includes a finger sleeve, a cutting section, and a protective section. The cutting section is arranged parallel to the length of the finger sleeve, and the protective section is movably connected to the cutting section. The finger sleeve is worn on the operator's thumb. The calyx of the young pear fruit is removed through the cutting section, and the protective section protects the operator's index finger during the calyx removal process.

[0009] As a further preferred embodiment of the above technical solution, the protective part is a fan-shaped plate, and the bottom end of the fan-shaped plate is hinged to the cut-off part.

[0010] Based on the above technical solution, an elastic element is further provided between the sector plate and the cut-off part.

[0011] Based on the above technical solution, a through groove is further provided at the bottom of the sector plate, and a connecting rod is provided at the through groove to connect the sector plate to the cut-off part.

[0012] Based on the above technical solution, furthermore, the upper end of the fan-shaped plate has multiple protective protrusions distributed at intervals.

[0013] Based on the above technical solution, a padding cotton is further provided on the fan-shaped plate, and the padding cotton is located below the protective protrusion.

[0014] As a further preferred embodiment of the above technical solution, the finger sleeve includes a cylindrical sleeve and a thumb sleeve. The cylindrical sleeve is connected to the cut-off portion, and the thumb sleeve is inserted into the cylindrical sleeve, with both ends of the thumb sleeve extending beyond the cylindrical sleeve.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. By setting up an integrated cylindrical sleeve and thumb sleeve, the thumb sleeve is worn behind the operator's thumb. The cylindrical sleeve not only protects the thumb, but also supports the cutting part, making it easier for the cutting part to exert force without causing damage to the thumb.

[0017] 2. By connecting the protective part to the cutting part, the cutting part is connected to the fan-shaped plate by a spring for traction. During the calyx removal operation, the fan-shaped plate blocks the cutting part, and at the same time, the protective protrusion restricts the front end of the tool knife, which effectively protects the operator's index finger and prevents the cutting part from causing injury to the operator's index finger when cutting the calyx.

[0018] 3. This utility model has a small and simple structure, is highly efficient in operation, and is highly safe. It brings great convenience to the decalyx removal process of pear-shaped fruits and has great practicality and promotional value. Attached Figure Description

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments. For those skilled in the art, other embodiments can be obtained without creative effort. Example 1

[0028] Reference Figure 1-4 This utility model provides an efficient calyx removal device for improving the shape of pears, including a finger sleeve 1, a cutting part 2, and a protective part 3. The cutting part 2 is arranged parallel to the length direction of the finger sleeve 1, and the protective part 3 is movably connected to the cutting part 2. When actually performing calyx removal, the finger sleeve 1 is worn on the operator's thumb, and the calyx part of the young pear is removed by the cutting part 2. During the calyx removal process, the protective part 3 is used to protect the operator's index finger so that the operator's index finger is not injured.

[0029] like Figure 2As shown, the finger sleeve 1 includes a cylindrical sleeve 11 and a thumb sleeve 12. The cylindrical sleeve 11 is connected to the cutting part 2. The thumb sleeve 12 is inserted into and fixed in the cylindrical sleeve 11, and both ends of the thumb sleeve 12 extend outside the cylindrical sleeve 11. In use, the thumb sleeve 12 is put on the operator's thumb. In this embodiment, the cylindrical sleeve 11 is made of rigid metal material, such as iron or stainless steel, and the thumb sleeve 12 is made of elastic material, such as rubber.

[0030] In some embodiments, the cutting part 2 is a small utility knife made of stainless steel, and the side wall of the small utility knife is fixedly connected to the cylindrical sleeve 11. It is understood that the small utility knife here can be a non-retractable type as shown in the figure. When this type of cutting part 2 is not in use, a sheath is usually put over the small utility knife for safety protection to avoid unnecessary accidental injury. The small utility knife can also be a telescopic utility knife as in the prior art, in which the blade is stored in the blade case for protection when not in use.

[0031] like Figure 2 As shown, the protective part 3 is a sector plate 31, the bottom end of which is hinged to the cutting part 2, and the length of the sector plate 31 is matched with the length of the cutting part 2. Specifically, a rectangular through groove 32 is opened at the bottom end of the sector plate 31, and a connecting rod 33 is horizontally connected in the through groove 32. A connecting hole 21 with a diameter that matches the connecting rod 33 is opened at the bottom end of the cutting part 2. The sector plate 31 is hinged to the bottom end of the cutting part 2 through the cooperation of the connecting rod 33 and the connecting hole 21.

[0032] In some embodiments, an elastic element 4 is provided between the sector plate 31 and the cut-off portion 2. In this embodiment, the elastic element 4 is a spring, and two elastic elements 4 are provided in total. Figure 2-4 As shown, an ear plate 22 is connected to both sides of the cutting part. The two ends of the elastic member 4 are fixedly connected to the ear plate 22 and the fan-shaped plate 31 respectively. When the operator presses the cutting part 2 with his thumb, the cutting part 2 compresses the spring and rotates around the connecting rod 33.

[0033] like Figure 2-3 As shown, a padding cotton 6 is also provided on the fan-shaped plate 31. The padding cotton 6 is located in the middle of the fan-shaped plate 31. The padding cotton 6 can be made of high-density sponge such as nano sponge. The padding cotton 6 protects the pear fruit during the calyx removal process and avoids unnecessary rubbing of the pear fruit during the calyx removal process. Example 2

[0034] Based on the above embodiment 1, in order to prevent the cutting part 2 from swinging and causing injury to the operator's index finger or other fingers other than the thumb when removing the calyx of the young pear fruit, the following further improvements are made to the structure of the fan-shaped plate 31.

[0035] like Figure 5-6 As shown, multiple protective protrusions 5 are evenly distributed at the upper end of the fan-shaped plate 31. The padding cotton 6 is located below the protective protrusions 5. The protective protrusions 5 can limit the upper end of the cutting part 2 when the cutting part 2 is near the fan-shaped plate 31 during the calyx removal process. In this embodiment, the protective protrusions 5 are triangular and there are five in total. The protective protrusions 5 divide the upper end of the fan-shaped plate 31 into four partitions. Any one of the partitions can limit the upper end of the cutting part 2 to prevent the cutting part 2 from swinging to both sides of the fan-shaped plate 31 and accidentally injuring the operator's fingers. Example 3

[0036] A highly efficient calyx removal device for improving pear fruit shape, which, in practical use, starts from the initial... Figures 1-2 The state becomes Figure 3 The status is as follows:

[0037] The operator puts the thumb sleeve 12 on their thumb. The cylindrical sleeve 11 on the outside of the thumb sleeve 12 protects the thumb and supports the cutting part 2. After putting on the thumb sleeve 12, the fan-shaped plate 31 is positioned inside the index finger. When performing the calyx removal operation, the operator holds the pear fruit between the index and middle fingers as usual, so that one end of the pear fruit's calyx is between the cutting part 2 and the fan-shaped plate 31. Then, the operator presses the cutting part 2 with their thumb. As the cutting part 2 compresses the elastic element 4, it rotates around the connecting rod 33. This causes the cutting part 2 to remove the calyx of the pear fruit as it approaches the fan-shaped plate 31, completing the calyx removal process. After the calyx removal process is completed, the upper end of the cutting part 2 is confined in any partition, which protects the operator's index finger.

[0038] It should be understood that the above detailed description of the embodiments of the present invention provided in the accompanying drawings is only for further explanation of the present invention and is not intended to limit the scope of the claimed present invention, but merely to illustrate selected embodiments of the present invention. Based on the embodiments of the present invention, any non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention are all within the protection scope of the present invention.
