Description

Technical Field

[0001] The invention relates to the technical field of fruit pitting equipment, and in particular to a petal breaking and pitting structure for fruits with complete pits. Background Art

[0002] During the deep processing of stone fruits, it is generally necessary to remove the core. For example, when yellow peaches are used to make canned yellow peaches, they need to be split open, and then the peach core is removed, and then the peach pulp is used for processing to obtain canned yellow peaches. In the prior art, fruit core removal can generally be carried out using mechanical equipment, such as a fruit core removal machine provided by a Chinese patent with authorization announcement number CN 112244306 B, which includes: an electric cylinder A, a connecting frame, a motor A, a gear, a rack, a support frame, a table, a mounting plate, a long strip, a core remover, an electric cylinder B, a T-shaped plate, a vacuum generator, a support seat, an electric push rod, an arc-shaped blade, and a gripper; the invention uses the electric cylinder A1 to push the connecting frame to extend and retract, thereby driving the gripper to grasp the fruit; the motor A drives the gear to rotate, thereby driving the long strip to move along the top of the mounting plate, and the electric cylinder B drives the vacuum generator to extend and retract to fix and absorb the fruit; the core is removed by the core remover, and the electric push rod drives the arc-shaped blade to separate the fruit; the invention realizes the integrated functions of fruit core removal, cutting, and collection into boxes through the cooperation of the above series of actions, and has the advantages of continuous work, fast core removal speed, high operation efficiency, and no clogging. During actual processing, a corer is used to press down to push out the core. Some fruits with complete cores, such as yellow peaches, have larger complete cores. During the downward pressure, the cores will impact the flesh below, causing the flesh below to be pushed out and broken (while other fruits, such as apples, do not have complete cores, the downward pressure process is smoother and the flesh is less adversely affected). After cutting, the subsequent flesh will be incomplete, which ultimately leads to poor sensory perception of the processed product. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] In an exemplary embodiment, Figure 1-7 As shown, this embodiment provides a structure for removing the petals and core of a fruit with a complete core.

[0031] It includes an upper mounting plate 1 and a lower mounting plate 2 that are fixedly arranged, and a first telescopic device 3 and a second telescopic device 4 are fixedly arranged on the upper mounting plate 1 and the lower mounting plate 2, respectively, and both of them can be cylinders, and the first telescopic device 3 and the second telescopic device 4 respectively have a first telescopic end 5 and a second telescopic end 6 extending downward and upward, and the first telescopic end 5 is rotatably connected to a first plug arm 7, and the second telescopic end 6 is fixedly connected to a second plug arm 8, and a supporting bowl 9 is further arranged between the first plug arm 7 and the second plug arm 8 for loading the fragile fruit 10 to be processed, and a through hole 11 and a pair of strip holes 12 connected to both sides of the through hole 11 are arranged at the bottom of the supporting bowl 9, and the second plug arm 8 can pass through the through hole 11 and the strip hole 12 upward to be inserted into the lower end of the fruit 10, and the first plug arm 7 is inserted downward into the upper end of the fruit 10, and the first plug arm 7 and the second plug arm 8 are arranged vertically opposite to each other. At the same time, the upper mounting plate 1 is also connected to a driving motor 13 that drives the first insertion arm 7 to rotate relative to the second insertion arm 8, so that the first insertion arm 7 rotates to twist the fruit 10 into two halves, and the core 42 is also separated accordingly, so that the obtained flesh is two halves and is more complete than the downward pressing method, which solves the problem in the prior art that when some fruits 10 with complete cores 42 are cored, the fruit 10 is easily broken by the top, resulting in incomplete flesh; in another embodiment, a similar driving motor 13 can also be provided on the lower mounting plate 2, and the second insertion arm 8 is also similarly rotatably connected to the second telescopic end 6, and the lower driving motor 13 and the upper driving motor 13 cause the first insertion arm 7 and the second insertion arm 8 to rotate in opposite directions, which can also twist the fruit 10 apart, and twisting the fruit 10 apart in this way is more efficient.

[0032] In more detailed schemes, such as Figure 1-8As shown, the first plug arm 7 includes a first connecting column 14 and a U-shaped first plug-in 15 fixedly connected to the first connecting column 14, the second plug arm 8 includes a second connecting column 16 and a U-shaped second plug-in 17 fixedly connected to the second connecting column 16, the first plug-in 15 and the second plug-in 17 can be arranged in mirror images up and down, the first plug-in 15 and the second plug-in 17 are arranged vertically opposite to each other and move back and forth toward each other, the first connecting column 14 is rotatably connected to the first telescopic end 5, the second connecting column 16 is fixedly connected to the second telescopic end 6 (or can also be rotatably connected in another embodiment), after the first plug-in 15 and the second plug-in 17 are inserted into the fruit 10, the core 42 of the fruit 10 is just embraced in the frame structure enclosed by them, and then the fruit 10 is broken apart by twisting, and the core 42 is separated. More specifically, during the process, the second plug-in Component 17 and first plug-in unit 15 first contact with the lower end and the upper end of fruit 10 at the same time, and then are inserted into fruit 10 at the same time. Finally, fruit 10 can be located in supporting bowl 9 to be broken apart, or it can be pushed above supporting bowl 9 and then broken apart, both of which can achieve synchronous petal separation and core removal. In contrast, when the two petals are broken apart after being pushed above supporting bowl 9, the two petals will fall downward, and the core 42 that is still partially connected to one of the petals will collide with supporting bowl 9 below after falling and will be more easily detached due to the impact. Even if part of the core 42 is still connected to one of the petals, it can be processed by vibration in the subsequent process, so that the core 42 is completely separated from the petals. At the same time, the petals and core 42 can be screened for subsequent processing (the petals enter the next processing step, and the core 42 is harmlessly treated or recycled for other uses).

[0033] like Figure 1-8As shown, in more detail, the first plug 15 includes a pair of first plug rods 18, the upper ends of the two first plug rods 18 are bent toward each other and fixedly connected to the first connecting column 14, the second plug 17 includes a pair of second plug rods 19, the lower ends of the two second plug rods 19 are bent toward each other and fixedly connected to the second connecting column 16, and overlapping tips are provided between the first plug rod 18 and the second plug rod 19. Specifically, a first plug sheet 20 is provided at the lower end of the first plug rod 18, and the first plug sheet 20 is a structure of thick upper and thin lower, and a second plug sheet 21 is provided at the upper end of the second plug rod 19, and the second plug sheet 21 is a structure of thin upper and thick lower, and the first plug sheet 20 and the second plug sheet 21 are provided. Such a structure has little resistance when entering the fruit 10, and can be better inserted into the fruit 10. At the same time, the lower end and the upper end of the first plug 20 and the second plug 21 can partially overlap, that is, the aforementioned overlapping tips can overlap, so that when twisting, the first plug rod 18 and the second plug rod 19 move in opposite directions relative to each other, and the fruit 10 can be twisted into two halves more completely; further, the ends of the first plug 20 and the second plug rod 21 can also be spike-shaped, and the rest of the first plug 20 and the second plug rod 21 (including the first plug rod 18 and the second plug rod 19) are sheet-like structures, so that twisting can better obtain two complete halves of fruit flesh.

[0034] like Figure 1-8As shown, the first connecting column 14 includes a first mounting section 22 rotatably connected to the first telescopic end 5, a first telescopic cavity 23 is coaxially arranged in the first mounting section 22, a first telescopic column 24 is arranged in the first telescopic cavity 23, and a first spring 25 is also arranged between the first telescopic column 24 and the first telescopic cavity 23, the first plug-in 15 is fixedly connected to the first telescopic column 24, a first vertical groove 26 is also recessed on the inner wall of the first telescopic cavity 23, the first telescopic column 24 is fixedly connected to a first vertical bar 27 that slides up and down in the first vertical groove 26, and the first mounting section The driven gear ring 28 is fixedly surrounded by the outer side of the first expansion joint 3, and the driving motor 13 is connected to the driving gear ring 29. When the first expansion joint 3 is running, the first expansion end 5 moves up and down, so that the first mounting section 22 moves up and down, so that the driven gear ring 28 also moves up and down accordingly. At this time, the driven gear ring 28 can be engaged with the driving gear ring 29 or staggered up and down. When engaged, the driving motor 13 drives the driven gear ring 28 to rotate, so that the first mounting section 22 rotates, and then the twisting is realized. In this scheme, a first telescopic column 24 is also provided, which can be assisted by the first spring 25. The first plug-in 15 is provided with elastic pressure by the help of the first plug-in 15, so that the first plug-in 15 first contacts with the fruit 10, and then is pressed tightly by the elastic pressure, and then further inserted into the fruit 10. During the process, the first vertical bar 27 and the first vertical groove 26 cooperate to prevent relative rotation between the first telescopic column 24 and the first mounting section 22, ensuring that the driving motor 13 drives the first plug-in 15 to rotate and achieve twisting; similarly, the second connecting column 16 includes a second mounting section 30 rotatably connected to the second telescopic end 6, and a second telescopic cavity 31 is coaxially arranged in the second mounting section 30. A second telescopic column 32 is provided in the second telescopic cavity 31, and a second spring 33 is also provided between the second telescopic column 32 and the second telescopic cavity 31. The second plug-in unit 17 is fixedly connected to the second telescopic column 32. A second vertical groove 34 is also recessed on the inner wall of the second telescopic cavity 31. The second telescopic column 32 is fixedly connected to a second vertical bar 35 which slides up and down in the second vertical groove 34. The second vertical bar 35 and the second vertical groove 34 also ensure that the second telescopic column 32 and the second mounting section 30 do not rotate relative to each other. The second spring 33 also functions similarly to the first spring 25.

[0035] like Figure 1-9As shown, the above scheme provides a situation of a supporting bowl 9, a first insert arm 7, and a second insert arm 8. In a further scheme, the number can be increased to further improve the processing capacity, that is, the present structure also includes a pair of annular conveying chains 36, and a plurality of connecting rods 37 are connected between the two conveying chains 36. A supporting plate 38 is arranged between two adjacent connecting rods 37, and a plurality of supporting bowls 9 are arranged on the supporting plate 38. The upper and lower parts of each supporting bowl 9 are respectively provided with a first insert arm 7 and a second insert arm 8, so that a plurality of fruits 10 can be processed at the same time, which greatly improves the processing efficiency; in some schemes, a one-to-one drive can be achieved by setting a plurality of first telescopic devices 3 and a plurality of second telescopic devices 4, and only synchronous operation is required; in other schemes, synchronous drive can be achieved by one or two first telescopic devices 3 and one or two second telescopic devices 4, specifically, the first telescopic end 5 is fixedly connected to the upper mounting bar 39, the second telescopic end 6 is fixedly connected to the lower mounting bar 40, and all the first connecting columns 14 and The upper mounting bar 39 is fixedly connected, and all the second connecting columns 16 are fixedly connected to the lower mounting bar 40; the drive motor 13 provided needs to correspond to the first plug arm 7 one by one and run synchronously (similarly, if another twisting method is adopted, that is, the first plug arm 7 and the second plug arm 8 rotate in opposite directions, the required drive motor 13 also corresponds to the second plug arm 8 one by one); in more detail, the operation mode of the conveying chains 36 on both sides is the same as that in the prior art, except that a connecting rod 37 is connected between them, and as they run, the connecting rod 37 also runs in a ring, so that the fruit 10 on the support plate 38 can be transported from one end to the other end, that is, the fruit 10 is sent to the processing place and the twisted pulp and core 42 are sent to the other end. The support plate 38 is long and has a plurality of trays 9 arranged horizontally, so that the present structure can process a plurality of fruits 10 at the same time, and the two ends of the support plate 38 are respectively connected to the connecting rod 37 by a ring 41 fixedly connected thereto, thereby ensuring smooth operation with the conveying chain 36.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
