Description

Technical Field

[0001] This utility model relates to the field of fruit processing technology, and in particular to a fruit pitting tool. Background Technology

[0002] Processing fruits can improve their flavor, increase their nutritional value and economic benefits, and effectively extend their supply period. Pitting stone fruits is a very important pre-processing step in the fruit processing industry. Pitted fruits can be used to make various foods.

[0003] A search of Chinese Patent Publication No. CN220875814U reveals a fruit pitter, comprising a base with a storage box inside. A handle is fixed to one side of the storage box, allowing the storage box to be pulled out from the base by gripping the handle and pulling it away from the base. Before pitting, the position of a limiting frame is adjusted. After pitting, as the pitting tube moves upward, the spring, pitting rod, and auxiliary tube move synchronously. When the pitting tube reaches a suitable height, the fruit is removed. Further raising the pressure rod moves the pitting tube, auxiliary tube, spring, and pitting rod. At this point, the upper surface of the pitting rod contacts the lower surface of the limiting frame, preventing further movement. As the pitting tube continues to move upward, the pit inside is pushed out by the pitting rod. By adjusting the position of the limiting frame, it can accommodate fruits of different sizes, preventing the pits from remaining inside the fruit and eliminating the need for manual removal, making it convenient to use.

[0004] However, in implementing the relevant technology, the above-mentioned fruit pitting device has the following problems: it is inconvenient to place the fruit directly below the center of the pitting tube when pitting the fruit, and the center of the pitting tube deviates greatly from the center of the fruit, resulting in incomplete pitting. Based on this, this utility model designs a fruit processing pitting tool to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fruit pitting tool to solve the problem mentioned in the background art that it is inconvenient to place the fruit directly below the center of the pitting tube when pitting fruit, resulting in incomplete pitting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fruit processing and pitting tool, including a base, wherein a receiving tube is snapped into the top of the base;

[0007] A support rod is fixedly installed on the top of the base, and a housing is fixedly connected to the top of the support rod. A sliding rod is slidably connected through the top of the housing, and a reset component is provided at the top of the sliding rod.

[0008] A laser positioning light is detachably connected inside the slide rod, and a sleeve is fixedly connected to the bottom end of the slide rod. A connecting tube is detachably connected inside the sleeve, and a core extraction tube is fixedly installed at the bottom of the connecting tube.

[0009] As a preferred embodiment, the reset assembly includes a top plate and a spring. The top plate is located at the top of the slide rod, and the spring is located at the bottom of the top plate. The bottom end of the spring is fixedly connected to the top of the housing.

[0010] As a preferred embodiment, gears are rotatably connected to both sides of the inner wall of the housing, and a toothed plate is fixedly installed on the outer wall of the slide rod, with the toothed plate meshing with the gears.

[0011] As a preferred embodiment, the inner sidewall of the slide bar is provided with a sliding groove, an arc groove and a limiting groove, and the outer sidewall of the laser positioning light is fixedly installed with a limiting block, and the limiting block and the limiting groove are engaged with each other.

[0012] As a preferred embodiment, a threaded rod is installed through the outer wall of the sleeve, and a threaded groove is formed on the outer wall of the connecting pipe, with the threaded rod and the threaded groove being threadedly connected.

[0013] As a preferred embodiment, a second spring is fixedly installed inside the support rod, and a pusher plate is slidably connected to the inner side wall of the support rod. The top end of the second spring is fixedly connected to the bottom end of the pusher plate.

[0014] As a preferred embodiment, the top of the base is provided with a through-hole circular groove, and the bearing tube is engaged with the circular groove.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Using the set receiving tube, laser positioning light and pitting tube, the fruit is placed on top of the receiving tube. The laser positioning light shines on the fruit, and the center of the fruit is moved to align with the laser irradiation position, reducing the deviation between the center of the pitting tube and the center of the fruit, thereby fully removing the pit.

[0017] 2. By using the pusher plate, gear and toothed plate, rotating the handle in the opposite direction drives the gear to rotate. The gear drives the slide rod to move upward through the toothed plate, so that the pit removal tube moves upward. The position of the pusher plate remains unchanged, which makes it easier to push out the pit inside the pit removal tube. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-7The fruit processing and pitting tool shown includes a base 1, with a receiving tube 10 snapped onto the top of the base 1. A support rod 2 is fixedly installed on the top of the base 1, and a housing 3 is fixedly connected to the top of the support rod 2. A sliding rod 4 is slidably connected through the top of the housing 3. A reset assembly 5 is provided at the top of the sliding rod 4. The reset assembly 5 includes a top plate 51 and a spring 52. The top plate 51 is located at the top of the sliding rod 4, and the spring 52 is located at the bottom of the top plate 51. The bottom end of the spring 52 is fixedly connected to the top of the housing 3. When the sliding rod 4 moves downward, the top plate 51 moves downward and presses the spring 52. A laser positioning light 6 is detachably connected inside the sliding rod 4. When the fruit is placed on top of the receiving tube 10, the laser from the laser positioning light 6 irradiates the fruit, moving the center of the fruit. Aligning with the laser irradiation position, a sleeve 7 is fixedly connected to the bottom of the slide rod 4. A connecting tube 8 is detachably connected inside the sleeve 7. A pitting tube 9 is fixedly installed at the bottom of the connecting tube 8. Gears 11 are rotatably connected to both sides of the inner wall of the outer shell 3. A toothed plate 12 is fixedly installed on the outer wall of the slide rod 4. The toothed plate 12 and the gear 11 are meshed together. Turning the handle downwards drives the gear 11 to rotate. The gear 11 drives the slide rod 4 downwards through the toothed plate 12. The slide rod 4 drives the pitting tube 9 downwards through the sleeve 7. The pitting tube 9 enters the center of the fruit and the pit is cut off inside the pitting tube 9. Releasing the handle, under the action of the spring 52, the top plate 51 resets the slide rod 4 and moves it upwards. The pitting tube 9 moves upwards with the slide rod 4, and the pitted fruit can be removed.

[0028] In this embodiment, as Figure 5 and Figure 7 As shown, the inner sidewall of the slide rod 4 is provided with a slide groove 13, an arc groove 14 and a limiting groove 15 respectively. The outer sidewall of the laser positioning light 6 is fixedly installed with limiting blocks 16. The limiting blocks 16 and the limiting grooves 15 are engaged with each other. When installing the laser positioning light 6, the core tube 9 is first removed. The limiting blocks 16 on the laser positioning light 6 slide upward along the slide groove 13. After the limiting blocks 16 can no longer move upward, the laser positioning light 6 is rotated to drive the limiting blocks 16 to move along the arc groove 14. After the limiting blocks 16 rotate to the top of the limiting groove 15, the laser positioning light 6 is released and moves downward under the action of gravity. The laser positioning light 6 drives the limiting blocks 16 to be engaged in the limiting groove 15, thus completing the installation of the laser positioning light 6. Conversely, it is convenient to disassemble the laser positioning light 6.

[0029] In this embodiment, as Figure 4 and Figure 5 As shown, a threaded rod 17 is installed through the outer wall of the sleeve 7, and a threaded groove 18 is opened on the outer wall of the connecting tube 8. The threaded rod 17 and the threaded groove 18 are threadedly connected. The pitting tube 9 can be disassembled by rotating the threaded rod 17 and the threaded groove 18 to facilitate the replacement of pitting tubes 9 with different diameters to accommodate fruits of different sizes. The connecting tube 8 at the top of the pitting tube 9 is inserted into the sleeve 7, and the installation of the pitting tube 9 is completed by rotating the threaded rod 17 and connecting it with the threaded groove 18.

[0030] In this embodiment, as Figure 2 As shown, a second spring 19 is fixedly installed inside the support rod 2. A pusher plate 20 is slidably connected to the inner side wall of the support rod 2. The top of the second spring 19 is fixedly connected to the bottom of the pusher plate 20. Rotating the handle in the opposite direction drives the gear 11 to rotate. The gear 11 drives the slide rod 4 to move upward through the toothed plate 12, and the pit-removing tube 9 moves upward. The position of the pusher plate 20 remains unchanged, pushing out the pit inside the pit-removing tube 9. The pusher plate 20 has through holes, so it will not block the laser emitted by the laser positioning light 6.

[0031] In this embodiment, as Figure 2 and Figure 4 As shown, a circular groove 21 is provided through the top of the base 1. The receiving tube 10 is engaged with the circular groove 21. The receiving tube 10 and the circular groove 21 can be moved directly upwards to facilitate the replacement of receiving tubes 10 with different diameters to accommodate fruits of different sizes. The fruit pits are pushed out and fall into the inner box of the base 1 for easy collection.

[0032] Working principle of this utility model: This utility model is a fruit processing and pitting tool. First, when using it, the fruit is placed on the top of the receiving tube 10, and the laser of the laser positioning light 6 is irradiated on the fruit. Move the center of the fruit to align with the laser irradiation position, turn the handle down to drive the gear 11 to rotate. The gear 11 drives the slide rod 4 to move down through the tooth plate 12, so that the top plate 51 moves down to squeeze the spring 52. The slide rod 4 drives the pitting tube 9 to move down through the sleeve 7. At this time, the push plate 20 will be pressed down and squeeze the spring 19 through the support rod 2. The pitting tube 9 enters the center of the fruit and the pit is cut and left in the pitting tube 9.

[0033] When the handle is released, the top plate 51 resets the slide bar 4 and moves upward under the action of spring 52. The pitting tube 9 moves upward with the slide bar 4. The pusher plate 20 is not squeezed by the pitting tube 9 and resets under the action of spring 19. Then the fruit is removed. The handle is turned in the opposite direction to drive the gear 11 to rotate. The gear 11 drives the slide bar 4 to move upward through the toothed plate 12. The pitting tube 9 moves upward with the slide bar 4. The position of the pusher plate 20 remains unchanged, and the pit inside the pitting tube 9 is pushed out.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
