Description

Technical Field

[0001] This utility model relates to the technical field of fruit processing equipment, specifically a semi-automatic pitter. Background Technology

[0002] In the deep processing of stone fruits (such as jujubes, hawthorns, apples, etc.), pitting is a key step in the production of dried fruits, candied fruits, and jams, and it directly affects the final quality of the product.

[0003] Currently, common manual pressing pitters mainly rely on manual operation, which has the problems of high labor intensity and low efficiency, making it difficult to meet the needs of mass production. In addition, most of these devices only support the through-penetration pitting mode, that is, the blade completely penetrates the fruit, and cannot achieve semi-penetration pitting (removing only the pit while keeping the flesh intact), thus limiting their application in the processing of new products such as stuffed fruits.

[0004] In addition, for fruits with pits tightly bound to the flesh or irregular shapes, existing pitting devices are prone to problems such as incomplete pitting and high pit residue rates.

[0005] Therefore, it is necessary to provide a semi-automatic device that is easy to operate, has good core removal effect, and supports dual-mode core removal. Summary of the Invention

[0006] The purpose of this invention is to provide a semi-automatic core remover to solve the problems of low core removal efficiency, single mode, and high residual core rate in the existing technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a semi-automatic pitter, including a pitter tube, a motor connecting rod at the top of the pitter tube, a serrated cutting ring at the bottom of the pitter tube, a pit discharge channel evenly opened in the middle of the pitter tube, and an arc-shaped cutting blade arranged in the inner circumference of the pitter tube, the arc-shaped cutting blade being used to hold and cut the fruit pit.

[0008] Preferably, the core removal cylinder has a connecting groove in the circumferential position below the core removal channel, and the core removal cylinder has a cylindrical structure; a central rotating shaft is installed in the connecting groove, a bushing is rotatably installed on the central rotating shaft, a connecting block is fixedly connected to the bushing, and the other end of the connecting block is fixedly connected to the arc-shaped cutting blade; the bottom end of the arc-shaped cutting blade has an axial through groove that meshes with the bushing and can generate radial movement as the core removal cylinder rotates.

[0009] Preferably, the arc-shaped cutting blade and the inner wall of the core removal cylinder are respectively fixedly provided with connecting hooks, and a reset mechanism is installed on the connecting hooks; the inner wall of the core removal cylinder has an opening corresponding to the connection between the connecting hook and the blade.

[0010] Preferably, the system also includes a power assembly, which includes a power motor and a connecting component; the power motor is connected to a motor connecting rod through the connecting component, and drives the core-removing cylinder to rotate synchronously with the motor connecting rod.

[0011] Preferably, the width of the core removal channel is smaller than the diameter of the bottom of the core removal cylinder.

[0012] Preferably, the reset mechanism is a spring, with its two ends connected to connecting hooks on the inner wall of the core removal cylinder and the upper surface of the arc-shaped cutting blade, respectively.

[0013] Preferably, the arc-shaped cutting blade has a beveled surface on the lower surface near the middle of the core-removing cylinder, and the inner surface of the serrated cutting ring has a conical outward expansion structure.

[0014] Preferably, the core removal cylinder is a replaceable structure with various inner and outer diameter specifications.

[0015] Compared with the prior art, the semi-automatic core remover provided by this utility model has the following beneficial effects:

[0016] The core innovation of this invention lies in its dual-mode pitting design, which simultaneously features both penetrating and semi-penetrating working modes. This design significantly broadens its application scenarios, enabling it to flexibly adapt to diverse fruit processing needs. To achieve efficient operation and reduce labor intensity, the equipment employs a semi-automatic drive, utilizing a motor to replace purely manual operation; this directly improves pitting efficiency.

[0017] In terms of operability and kernel removal effectiveness: The rational structural design of this solution ensures smooth pitting, and the optimized pit discharge channel facilitates seamless pit separation and discharge, making the overall operation convenient. The crucial pitting action is accomplished by circumferentially distributed rotating arc-shaped cutting blades. These blades work in conjunction with a flexible reset mechanism: the blades effectively cut and hold pits of different shapes, while the flexible reset mechanism ensures timely repositioning and provides cushioning protection. This synergistic effect directly results in excellent pitting performance, effectively reducing the residual pit rate. The equipment's versatility is reflected in the availability of pitting cylinders of various diameters, adaptable to fruits of different sizes, greatly expanding its applicability. Furthermore, the flexible reset mechanism not only ensures effective pitting but its cushioning protection function also significantly improves the structural reliability of the equipment, helping to extend its service life. Details are as follows: 1. Dual-mode core removal: It innovatively realizes two modes, penetrating and semi-penetrating, which broadens the application scenarios and meets diverse processing needs.

[0018] 2. Semi-automated and efficient operation: Using motor drive to replace purely manual operation reduces labor intensity and significantly improves kernel removal efficiency.

[0019] 3. Easy to operate: The structure is reasonably designed, the pitting action is smooth, and the separation and discharge of the pit are smooth.

[0020] 4. Excellent pitting effect: The circumferentially distributed rotating arc-shaped cutting blades work together with the elastic reset mechanism to effectively cut and hold fruit pits of different shapes, reducing residual pits.

[0021] 5. High versatility: Pitting tubes of various diameters are suitable for fruits of different sizes and have a wide range of applications.

[0022] 6. Reliable structure: The elastic reset mechanism ensures that the blades are reset in time, while also providing buffer protection and extending the service life of the equipment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] For an example, please refer to... Figures 1 to 5 As shown: To address the problems mentioned in the technical solutions, this application provides a semi-automatic pitter, including a pitter cylinder 2, a motor connecting rod 1 at the top of the pitter cylinder 2, a serrated cutting ring 9 at the bottom of the pitter cylinder 2, a pit discharge channel 3 evenly distributed around the middle circumference of the pitter cylinder 2, and an arc-shaped cutting blade 7 arranged around the middle circumference of the pitter cylinder 2 for cutting and removing fruit pits. The core removal cylinder 2 has a connecting groove on its circumference near the core discharge channel 3, and a central rotating shaft 8 is installed in the connecting groove. A bushing 5 is rotatably installed on the outer surface of the central rotating shaft 8. A connecting block is fixedly connected to the bushing 5, and the end of the connecting block away from the bushing 5 is fixedly connected to the arc-shaped cutting blade 7. The arc-shaped cutting blade 7 and the inner wall of the core tube 2 are respectively fixedly installed with connecting hooks 6, and a reset mechanism 4 is installed on the connecting hooks 6; the power assembly includes a power motor and a connecting assembly; the power motor is connected to the motor connecting rod 1 through the connecting assembly, so that the core removal tube 2 rotates synchronously with the connecting rod 1; the width of the core removal channel 3 is smaller than the diameter of the bottom of the core removal tube 2; Among them, the reset mechanism 4 is a spring; the two ends of the spring are respectively installed on the connecting hook 6 on the inner wall of the core removal cylinder 2 and the upper surface of the arc-shaped cutting blade 7; The arc-shaped cutting blade 7 has an angled surface on the lower surface near the middle of the core removal cylinder 2, and the inner surface of the serrated cutting ring 9 has a conical outward expansion structure; like Figure 1-5 As shown, the semi-automatic pitting device provided by this utility model has a core component of a pitting cylinder 2. The pitting cylinder 2 has a cylindrical structure and is preferably made of metal to ensure strength and durability. A motor connecting rod 1 is integrally provided at the top of the pitting cylinder 2 for connecting to the drive device.

[0028] Inside the lower end of the core removal cylinder 2, a bushing 5 is mounted via a central rotating shaft 8. Three sets (or other suitable numbers) of arc-shaped cutting blades 7 are evenly distributed circumferentially on the inner wall of the core removal cylinder 2. Each arc-shaped cutting blade 7 has an axial through groove at its bottom end, which meshes with the bushing 5, allowing it to rotate radially with the core removal cylinder 2.

[0029] Each arc-shaped cutting blade 7 has a connecting hook 6 fixedly connected to its top end. The connecting hook 6 is connected to the inner wall of the core-removing cylinder 2 via an elastic reset mechanism 4, specifically a tension spring. One end of the spring is connected to the connecting hook 6, and the other end is connected to a pre-set connection point on the inner wall of the core-removing cylinder 2. An opening is provided on the inner wall of the core-removing cylinder 2 at the connection point between the connecting hook 6 and the blade 7 to provide space for the connection to move. In the non-working state, the tension of the spring keeps the arc-shaped cutting blade 7 in a roughly horizontal position.

[0030] The bottom edge of the core removal cylinder 2 is provided with a serrated cutting ring 9, and the outer wall above the serrated cutting ring 9 is provided with a core discharge channel 3, the width of which is smaller than the bottom diameter of the core removal cylinder 2, for the discharge of the core after semi-penetrating core removal or penetrating core removal.

[0031] To accommodate the pitting needs of fruits of different sizes, the pitting cylinder 2 can be manufactured in various specifications with different inner and / or outer diameters, forming a replaceable pitting cylinder assembly. Users select the appropriate pitting cylinder 2 according to the size of the fruit and pit, and install it onto the drive source via the connecting rod 1.

[0032] The specific implementation process described above is as follows: Pitting through: Select a pitting cylinder 2 of appropriate size, connect and start the power motor; the rotating serrated cutting ring 9 is aligned with the fruit and pressed down to cut into the pulp; the arc-shaped cutting blade 7 is brought towards the center under centrifugal force and meshing with the bushing 5, rotating to cut and wrap the pit, thus achieving separation; the pit is discharged through the pit discharge channel 3.

[0033] Semi-penetrating pitting: The operation is the same as the penetrating method. When the curved cutting blade 7 rotates and cuts into and contacts the pit, the resistance of the pit causes the curved cutting blade 7 to overcome the pulling force of the elastic reset mechanism 4, and swings within the opening through the connecting hook 6 to "lock" the pit; the reverse lifting device then pulls the pit out with the blade without penetrating the fruit; after completion, the elastic reset mechanism 4 drives the blade to return to a horizontal position, and the pit falls out and is discharged. This utility model achieves efficient, dual-mode pitting function through innovative pitting cylinder structure, especially the meshing mechanism between the curved cutting blade 7 and the bushing 5 and the synergy of the elastic reset mechanism 4, with significant practical value.
