A tangerine tea fruit shell end removing device

Abstract

This invention provides a device for removing the end of citrus peel from tangerines and oranges, belonging to the field of citrus peel preparation technology. It includes a base component, a rotating frame assembly, a perforation assembly, an end-hole-digging assembly, and a pulp separation assembly. The corner frame is connected to the base component at multiple points, allowing the outer cone and pulp separation blade to move to different positions. After perforation (end-hole digging) is completed in the center of the citrus, two different removal modes can be achieved. The end-hole-digging disc, which is elastically connected to the insertion rod, not only digs holes at the end of the citrus but also, when the citrus enters the pulp separation step, pressing the end-hole-digging disc causes the active locking teeth and transmission locking teeth to engage. This drives the transmission rotating sleeve to periodically engage with the passive locking teeth via an elastic insert block. This allows for accurate pulp separation after the pulp separation blade is inserted into the citrus from the end and the citrus is positioned within the receiving and limiting plate, by pressing and rotating the end-hole-digging disc.

Description

Technical Field

[0001] This invention relates to the field of citrus fruit peel preparation technology, and in particular to a device for removing the end of citrus fruit peel. Background Technology

[0002] Currently, the processing of tangerine peel in the production of tangerine tea mainly involves two core steps: cutting a hole at the end and separating the pulp. Traditional methods rely heavily on manual operation, where workers use knives or special scoops to cut and cut a hole at the end of the tangerine, then insert the scoop into the fruit or crush and pour out the pulp.

[0003] This purely manual method demands a high level of skill from the operators. Inconsistencies in the force and angle of the manual operation can directly lead to variations in the size of the holes in the fruit shells, increased burrs on the edges, and even damage to the shells, affecting the final appearance of the tea. Furthermore, because both piercing and removing the kernels require sharp tools, operators are highly susceptible to hand injuries and other safety accidents during prolonged manual work. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing the end of the peel of citrus fruit, in order to solve the problems of low standardization of manual operation, easy damage to the peel and poor safety in the prior art, and to realize the standardized operation of central perforation, end hole drilling and pulp separation of citrus peel.

[0005] The purpose of this invention is achieved through the following technical solution: a device for removing the end of citrus peel, comprising a base component, a rotating frame component, a perforation component, an end-hole-digging component, and a pulp separation component. The rotating frame component includes a corner frame, the perforation component includes an outer cone, the end-hole-digging component includes a digging blade, and the pulp separation component includes a connecting platform and a passive locking tooth. One end of the corner bracket is screwed to one side of the main body of the base component, one side of the outer wall of the outer cone is fixed to the corner bracket, and the other end of the corner bracket is fixed to a plug rod. The head end of the plug rod is provided with a through-cutting edge, and a detachable cone head is installed in the middle of the head end of the through-cutting edge. The outer cone has a flared opening structure, and the plug rod is inserted into the middle of the outer cone. The end-hole-digging disc is elastically inserted into the outside of the insert rod on the side facing the outer cone cylinder, and the digging cutting edge is located at the head end of the end-hole-digging disc, which is a non-complete cutting edge structure. The other end of the corner frame has a rod fixing hole. The end of the rod is fixed to the rod fixing hole through evenly distributed connecting platforms. Both sides of the top of the connecting platform have a disengagement slope. A passive sleeve is also screwed to the bottom of the other end of the corner frame. A pulp separating knife is fixed to the bottom of the passive sleeve. A transmission sleeve is also screwed to the end of the rod. Passive locking teeth are evenly fixed to the top of the passive sleeve. An elastic plug is elastically slidably connected to the main body of the transmission sleeve towards the connecting platform. Both sides of the bottom of the elastic plug have locking slopes. Pressing the end hole-cutting plate towards the transmission sleeve can make the bottom of the end hole-cutting plate engage with the top of the transmission sleeve.

[0006] The technical solution of this invention is used as follows: The order of drilling holes in the peel of oranges and tangerines using this device is to first drill a hole in the center and then drill holes at the ends. Before operation, the flared opening end of the outer cone should face upwards. During operation, hold the orange and tangerine, align its center with the insert rod, and press it into the insert rod from top to bottom. Since the end of the insert rod has a perforated blade, the orange and tangerine can be smoothly pressed into the insert rod, and the insert rod penetrates the center of the orange and tangerine, completing the center perforation. At this time, the bottom of the tangerine peel is in contact with the cutting edge of the end-hole-digging plate. Press the end-hole-digging plate away from the outer cone cylinder, so that the end-hole-digging plate moves to the position where the bottom contacts the top of the transmission sleeve. Then quickly release the end-hole-digging plate. Under the support of the elastic force of the end-hole-digging plate towards the outer cone cylinder, the end-hole-digging plate will quickly move upward, pass through the channel opened in the bottom wall of the outer cone cylinder, and complete the digging of the end of the tangerine peel through the cutting edge. Furthermore, the cutting edge of the hole-digging tool is not a complete cutting edge structure, which means that after the hole is dug out, the part of the orange peel that has been removed from the end of the peel is still not completely separated from the main body of the peel. Then, remove the tangerine after the hole has been dug. There are two ways to remove it: Method 1: With the flared end of the outer cone facing upwards, manually remove the tangerine after drilling the hole. This method is convenient. Since the outside of the insert is smooth, the tangerine can be easily removed by gently pulling it. However, the operator should be careful not to touch the cutting edge of the hole with their hands to avoid damage. Method 2: Fixed-point rotating corner bracket, which allows the oranges to slide out under their own weight as the flared opening of the outer cone rotates downwards, ensuring high safety; After the tangerines with holes dug are removed, the pulp separation step begins. The corner frame is rotated at a fixed point so that it drives the pulp separation blade to rotate to a position where it can be easily inserted into the tangerine from the hole dug at the end of the tangerine peel, and the curved edge of the pulp separation blade enters between the peel and the pulp. Hold the orange with the pulp separation knife inserted into place, rotate the corner bracket to the position where the outer cone flare opening is facing upwards. At this point, the orange can be placed on the top of the base component. Hold the orange with one hand to fix its position, and press the end hole-drilling plate on one side of the transmission sleeve with the other hand so that the bottom of the end hole-drilling plate and the top of the transmission sleeve form an interlocking connection. Subsequently, manually rotate the end-hole-drilling disc to drive the rotation of the transmission sleeve. The transmission sleeve can drive the rotation of the elastic insert, so that within the gap between any two adjacent sets of connecting platforms, the elastic insert can form an elastic engagement with the passive engagement teeth opened at the top of the passive sleeve through the engagement bevel, thereby driving the rotation of the passive sleeve and the pulp separation knife. When the elastic plug rotates to the position of contacting the connecting table, the snap-fit ​​inclined surface and the disengagement inclined surface will form a sliding tangential fit. After the transmission sleeve continues to rotate, the elastic plug can overcome the supporting elastic force on the side facing the connecting table, drive the elastic plug to retract and pass over the connecting table, and enter the next set of gaps composed of adjacent connecting tables. Furthermore, the space provided by the gap between adjacent connecting platforms is sufficient to drive the elastic plug and the passive locking tooth to rotate within a certain angle range, so that after the continuous rotation of the transmission sleeve, the elastic locking engagement formed by the elastic plug and the passive locking tooth under the condition of the connecting platform interval can drive the passive sleeve to rotate at least one full path rotation. By fixing the tangerine in a certain position, the curved blade of the pulp separator rotates between the tangerine peel and the pulp, which can not only separate the peel from the pulp, but also separate the end of the peel that has been removed from the main body.

[0007] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) This invention integrates the functions of central perforation, end perforation and pulp separation, which can significantly improve the standardization and efficiency of processing. The cooperation between the insert rod and the end perforation plate can first complete the center positioning of the citrus and then carry out the end removal work, which is suitable for standard citrus with a diameter within a certain range. The manual and gravity-assisted fruit picking methods can be flexibly switched to adapt to different operating conditions and reduce the difficulty and labor intensity of manual operation. (2) Based on the multi-point positioning and rotation of the corner frame, this invention can ensure that the orange peel slides down with gravity assistance after the hole is dug, and can also realize the non-interference insertion of the pulp separation knife, which makes it convenient to realize the subsequent pulp separation steps in a limited operating space. (3) The elastic engagement between the elastic insert and the passive snap-fit ​​teeth of the present invention, as well as the ability of the elastic insert to pass over the connecting platform, can not only make the end of the insert rod fixedly connected to the corner frame through the connecting platform, so that the corner frame, the insert rod and the outer cone are connected to form an integral structure, but also effectively transmit the rotational torque of the transmission sleeve to the passive sleeve, so that the hole-digging operation of the end of the orange peel and the pulp separation operation can be completed by manually operating the end hole-digging plate, which improves the convenience of operation.

[0013] Example 1: This invention is based on a base component 1, a rotating frame assembly 2, a perforation assembly 3, an end-hole-cutting assembly 4, and a pulp separation assembly 6. Examples of the standard process for perforating the center, cutting holes at the ends, and separating the pulp of citrus fruits are provided below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown; One end of the corner bracket 206 in the rotating frame assembly 2 is screwed to one side of the main body of the base component 1, and the corner bracket 206 can rotate at multiple points relative to the base component 1. One side of the outer wall of the outer cone 301 is fixed to the corner bracket 206 without interfering with the rotation of the corner bracket 206. The other end of the corner bracket 206 is fixed to the insertion rod 303. The head end of the insertion rod 303 is provided with a through-cutting edge 304. The outer cone 301 has a flared opening structure, and the insertion rod 303 is inserted into the middle of the outer cone 301. The position of the perforating blade 304 should be lower than the flared opening of the outer cone 301 to facilitate the center perforation and handling of the oranges; The end-hole-digging disc 401 is elastically inserted into the outer side of the insert rod 303 on the side facing the outer cone 301. The digging cutting edge 404 is located at the head end of the end-hole-digging disc 401 and is a non-complete cutting edge structure. The bottom wall of the outer cone 301 has a channel that allows the end-hole-digging disc 401 to pass through. In the free state, the digging cutting edge 404 at the head end of the end-hole-digging disc 401 is located in the inner cavity of the outer cone 301. The other end of the corner bracket 206 has a rod fixing hole 605. The outer end of the rod 303 is fixed to the rod fixing hole 605 through evenly distributed connecting platforms 606. Both sides of the top of the connecting platform 606 have a disengagement slope 607. The bottom of the other end of the corner bracket 206 is also screwed with a passive rotating sleeve 608. The bottom end of the passive rotating sleeve 608 is fixed with a pulp separating knife 601. The end of the rod 303 is also screwed with a transmission rotating sleeve 603, and the transmission rotating sleeve 603 is connected to the corner bracket 206. The corner brackets 206 do not contact each other. The passive locking teeth 611 are evenly fixed on the top of the passive rotating sleeve 608. The main body of the transmission rotating sleeve 603 is elastically slidably connected to the side facing the connecting platform 606. The bottom end of the elastic locking block 612 is provided with locking slopes 613 on both sides. In the free state, the elastic locking block 612 can pass through the gap between adjacent connecting platforms 606 and form an elastic locking engagement with the passive locking teeth 611 through the locking slopes 613.

[0014] Pressing the end-hole plate 401 forcefully toward one side of the transmission sleeve 603 will cause the bottom end of the end-hole plate 401 to engage with the top end of the transmission sleeve 603. The working principle is as follows: The device makes holes in the peel of tangerines by first drilling a hole in the center and then digging holes at the ends. The diameter of the central hole is 6-8 mm, and the diameter of the digging holes is controlled at 22-25 mm. The tangerines used to make tangerine tea are strictly selected, requiring that the peel has dense oil cells, clear texture, no scars, moderate peel hardness, and a diameter of 4.5-5 cm. Before operation, the flared opening end of the outer cone 301 should face upwards; During operation, hold the orange and tangerine, align its center with the insertion rod 303, and press it into the insertion rod 303 from top to bottom. Since the insertion rod 303 has a perforated cutting edge 304 at its head end, the orange and tangerine can be smoothly pressed into the insertion rod 303, and the insertion rod 303 penetrates the center of the orange and tangerine, completing the center perforation. At this time, the bottom of the tangerine peel is in contact with the cutting edge 404 at the top of the end-hole-digging plate 401. Press the end-hole-digging plate 401 away from the outer cone 301, so that the end-hole-digging plate 401 moves to the position where it contacts the top of the transmission sleeve 603. Then quickly release the end-hole-digging plate 401. Under the action of the supporting elastic force of the end-hole-digging plate 401 towards the outer cone 301, the end-hole-digging plate 401 will quickly move upward, pass through the channel opened in the bottom wall of the outer cone 301, and complete the digging of the end of the tangerine peel through the cutting edge 404. Because the 404 cutting edge of the hole-digging tool is thin and sharp, it can smoothly remove the end of the orange peel under a certain pressure. Furthermore, the cutting edge 404 is a non-complete cutting edge structure, which means that after the hole is dug, the part of the orange peel that is removed from the end is not completely separated from the main body of the peel. Moreover, the connection between the removed end of the orange peel and the main body can support the end of the orange peel to be removed with the main body without separation. Then, remove the tangerines after the holes have been dug. There are two ways to remove them: Method 1: With the flared end of the outer cone 301 facing upwards, the oranges with the hole dug can be removed manually. This method is convenient. Since the outside of the insertion rod 303 is smooth, the oranges can be easily removed by gently pulling them. However, this method requires the operator to avoid touching the perforating edge 304 with their hands to prevent damage. Method 2: Fixed-point rotating corner bracket 206, which allows the oranges to slide out under their own weight as the flared opening end of the outer cone 301 rotates downward, ensuring high safety. After the tangerines with holes dug are removed, the pulp separation step begins. The corner bracket 206 is rotated at a fixed point so that the corner bracket 206 drives the pulp separation knife 601 to rotate to a position where it can be easily inserted into the tangerine from the hole dug at the end of the tangerine peel, and so that the arc-shaped blade of the pulp separation knife 601 enters between the peel and the pulp. Holding the orange with the pulp separation knife 601 inserted in place, rotate the corner bracket 206 to a position where the flared end of the outer cone 301 faces upward. At this time, the orange can be placed on the top of the main body of the base component 1. Hold the orange with one hand to fix its position, and press the end hole-drilling plate 401 on one side of the transmission sleeve 603 with the other hand so that the bottom end of the end hole-drilling plate 401 and the top end of the transmission sleeve 603 form an interlocking connection. Subsequently, manually rotate the end perforated plate 401 to drive the rotation of the transmission sleeve 603. The transmission sleeve 603 can drive the rotation of the elastic insert 612, so that within the gap between any two adjacent sets of connecting platforms 606, the elastic insert 612 can form an elastic engagement with the passive engagement tooth 611 opened at the top of the passive sleeve 608 through the engagement inclined surface 613, thereby driving the rotation of the passive sleeve 608 and the pulp separation knife 601. This is because when the snap-fit ​​inclined surface 613 at the head end of the elastic plug 612 is located in the gap between any two sets of connecting platforms 606, under the action of the supporting elastic force on the elastic plug 612, the pointed structure formed by the snap-fit ​​inclined surface 613 on both sides of the head end of the elastic plug 612 will be elastically snapped into any set of tooth grooves of the passive snap-fit ​​tooth 611, forming an elastic snap-fit. Furthermore, the supporting elastic force on the elastic insert 612 is much greater than the resistance encountered when the pulp separating blade 601 rotates, enabling the elastic insert 612 to serve as an effective transmission component, driving the pulp separating blade 601 to perform the pulp separation action. When the elastic plug 612 rotates to the position where it contacts the connecting platform 606, the locking inclined surface 613 and the disengaging inclined surface 607 will form a sliding tangential fit. After the transmission sleeve 603 continues to rotate, the elastic plug 612 can overcome the supporting elastic force on the side facing the connecting platform 606, and drive the elastic plug 612 to retract and pass over the connecting platform 606, and enter the next set of gaps formed by adjacent connecting platforms 606. In order to satisfy the requirement that the snap-fit ​​inclined surface 613 at the head end of the elastic plug 612 can form an elastic snap-fit ​​engagement with the passive snap-fit ​​tooth 611 and an elastic sliding tangential engagement with the displacement inclined surface 607, the snap-fit ​​inclined surface 613 at the head end of the elastic plug 612 must have a sufficient amount of protrusion relative to the connecting platform 606 when it is not in contact with the displacement inclined surface 607. This allows the snap-fit ​​inclined surface 613 to stably form an elastic snap-fit ​​engagement. Furthermore, the size of the snap-fit ​​inclined surface 613 can simultaneously form an elastic snap-fit ​​engagement with the passive snap-fit ​​tooth 611 and an elastic tangential engagement with the displacement inclined surface 607. This allows the snap-fit ​​inclined surface 613 to smoothly form an elastic sliding tangential engagement with the displacement inclined surface 607 and pass over the connecting platform 606 when it encounters resistance from the displacement inclined surface 607. Furthermore, the space provided by the gap between adjacent connecting platforms 606 is sufficient to drive the elastic plug 612 and the passive locking tooth 611 to rotate within a certain angle range, so that after the continuous rotation of the transmission sleeve 603, the elastic locking engagement formed by the elastic plug 612 and the passive locking tooth 611 under the interval of the connecting platform 606 can drive the passive sleeve 608 to rotate at least one full path. By fixing the tangerine in a certain position, the arc-shaped blade of the pulp separation knife 601 rotates between the tangerine peel and the pulp, which can not only separate the peel from the pulp, but also separate the end of the tangerine peel that has been removed from the connection part of the main body. Furthermore, when manually rotating the end perforating disc 401, a uniform and slow rotation should be maintained to avoid rapid rotation that could cause the fruit shell to crack. Remove the peel from one end of the tangerine to create a tea filling opening. After pouring out the separated pulp, wash and dry the empty peel to prepare it for filling with tea leaves to make tangerine tea. The removed end should be retained to form an end cap after filling with tea leaves.

[0015] The specific structures of base component 1, rotating frame assembly 2, and perforation assembly 3 are as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the base plate 101 serves as the main support for the base component 1, the upright plate 102 is vertically fixed to one side of the top of the base plate 101, the receiving limiting plate 103 is fixed to the top of the base plate 101, and after the corner frame 206 rotates to the position where the flared opening end of the outer cone 301 faces upward, the center of the insertion rod 303 is coaxial with the center of the receiving limiting plate 103. One side of the receiving and limiting plate 103 is open to eliminate interference with the rotation of the pulp separating knife 601 and the connecting seat 306. When the arc-shaped blade of the pulp separating knife 601 enters the gap between the fruit peel and the pulp through the hole at the end of the tangerine, the corner bracket 206 rotates at a fixed point, driving the tangerine into the receiving and limiting plate 103, so that the outer wall of the tangerine fits against the receiving and limiting plate 103. At this time, the coaxiality between the center of the tangerine and the center of the insert rod 303 is within the allowable range, which allows the pulp separating work and the complete separation of the end of the fruit peel from the main body to be performed with high precision as the pulp separating knife 601 rotates around the insert rod 303. Compared with the traditional method of digging holes and removing pulp by hand, the problem of damage to the fruit peel can be avoided. The rotating base 201 is fixedly installed on the top of the upright plate 102. The side of the upright plate 102 is provided with a rotating slide groove 202 centered on the rotating base 201. The first positioning slot 203, the third positioning slot 205 and the second positioning slot 204 are arranged in the rotating slide groove 202, which can provide positioning points at different positions for the corner frame 206. A handrail 207 is fixed on one side of the corner bracket 206 to facilitate manual rotation of the corner bracket 206; A spindle 208 is screwed into the rotary seat 201. A retaining seat 209 is fixed to one end of the spindle 208. A retaining hole 210 is opened at the top of one end of the corner bracket 206, and the retaining seat 209 is secured in the retaining hole 210. The corner bracket 206 has a telescopic slide groove 212 in the main body at one end. The positioning pin 211 is fixedly connected to the telescopic slider 213. The telescopic slider 213 is slidably connected in the telescopic slide groove 212 and will not detach from the telescopic slide groove 212. The positioning pin 211 is slidably connected in the rotating slide groove 202. One end of the compression spring 214 is secured to one side of the inner surface of the telescopic slide 212, and the other end is secured to the telescopic slider 213. It can provide the telescopic slider 213 with a supporting elastic force away from the main shaft 208, so that as the corner bracket 206 rotates, the positioning pin 211 can slide in the rotating slide 202 and elastically engage in the first positioning slot 203, the third positioning slot 205 or the second positioning slot 204. Furthermore, the limited range of support elasticity provided by the compression spring 214 allows the positioning pin 211 to be dislodged from the first positioning slot 203, the third positioning slot 205, or the second positioning slot 204 after a certain torque is applied to the corner bracket 206. When the corner bracket 206 rotates to the position where the positioning pin 211 is elastically engaged in the first positioning slot 203, the outer cone 301 is in a state where the flared opening end faces upward. When the corner bracket 206 rotates to the position where the positioning pin 211 is elastically engaged in the second positioning slot 204, the outer cone 301 is in a state where the flared opening end faces downward. When the corner bracket 206 rotates to the position where the positioning pin 211 is elastically engaged in the third positioning slot 205, the pulp separating knife 601 rotates to the position where its arc-shaped cutting edge enters the gap from the end of the tangerine and enters the position where there is no interference between the peel and the pulp. The upper side wall of the outer cone 301 is symmetrically provided with side ear holes 302, which facilitates the central positioning and drilling of oranges through the insertion rod 303 and the removal of oranges after the end holes are dug. A detachable cone 305 is installed at the middle of the tip of the piercing blade 304 to guide the citrus to be pierced in the center, prevent the fruit from slipping sideways in the early stage of force application, and ensure accurate piercing position. A connecting seat 306 is fixed to the outer side wall of the outer cone 301. The connecting seat 306 is fixed to the end of the locking seat 209, which will not affect the locking of the locking hole 210 and the locking seat 209. The bottom hole 307 is opened in the middle of the bottom wall of the outer cone 301. The middle fixing plate 308 is fixed to the middle of the insertion rod 303 by the reinforcing plate 309. The purpose of setting the reinforcing plate 309 is to form a stable support between the insertion rod 303 and the thin-walled middle fixing plate 308. A channel is formed between the outer surface of the middle fixing plate 308 and the inner surface of the bottom hole 307 to allow the end hole-drilling plate 401 to pass through.

[0016] The specific structures of the end-hole punching assembly 4 and the pulp separation assembly 6 are as follows: Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, a rotating wheel 402 is fixed to the lower outer side of the end hole-digging disc 401 to facilitate manual operation of the end hole-digging disc 401. A sliding sleeve 405 is fixed at the middle of the bottom end of the end-hole-drilling plate 401. The end-hole-drilling plate 401 is inserted into the insertion rod 303 through the sliding sleeve 405. The inner ring of the bearing 406 is fixed to the top of the sliding sleeve 405. A top spring 403 is fitted on the outside of the insertion rod 303. One end of the top spring 403 is fixed to the corner bracket 206, and the other end is fixed to the outer ring of the bearing 406. It can provide the end-hole-drilling plate 401 with a supporting elastic force towards the outer cone 301. Due to the setting of the bearing 406, the end-hole-drilling plate 401 can still be rotated manually smoothly when the top spring 403 is in a compressed state. Bearing 406 is a general-purpose rolling bearing, such as the angular contact ball bearing in GB / T 292-1994, which is a bearing with the size series designation 10; The active locking teeth 602 are evenly fixed at the bottom end of the sliding sleeve 405, and the transmission locking teeth 604 are evenly fixed at the top end of the transmission sleeve 603. After overcoming the supporting elastic force of the top spring 403 and pressing the end hole-drilling plate 401 down to a certain position, the active locking teeth 602 and the transmission locking teeth 604 can mesh with each other, forming an effective torque transmission connection between the sliding sleeve 405 and the transmission sleeve 603. This allows the manual rotation of the end hole-drilling plate 401 and the sliding sleeve 405 to drive the rotation of the transmission sleeve 603 when a certain downward pressure is applied to the end hole-drilling plate 401. The stud 609 is coaxially fixed to the bottom end of the insert rod 303. The threaded fastening fit between the fixing nut 610 and the stud 609 can limit the passive sleeve 608 between the inner surface of the insert rod fixing hole 605 and the outer surface of the bottom end of the insert rod 303, so that the passive sleeve 608 can rotate freely and safely. Furthermore, the bottom area of ​​the connecting platform 606 is sufficient to support the contact and engagement of the array of passive locking teeth 611, so that the passive rotating sleeve 608 can only rotate axially and will not displace axially. Sufficient space is left at the connection position between the pulp separating blade 601 and the passive sleeve 608 to facilitate the engagement of the fixing nut 610 and the stud 609. The main body of the transmission sleeve 603 has an elastic slot 614. Both sides of the elastic slot 614 have limit ear grooves 615. Both ends of the elastic plug 612 are fixed with ear sliding posts 616. The ear sliding posts 616 slide into the slide channel formed by the elastic slot 614 and the limit ear grooves 615 along with the elastic plug 612. The push spring 617 is locked between the top of the elastic plug 612 and the inner bottom end of the elastic slot 614, which can provide support elastic force for the locking slope 613 towards the connecting platform 606 and the passive locking tooth 611. Furthermore, the supporting elastic force provided by the push spring 617 is sufficient to drive the pointed structure formed by the snapping inclined surface 613 on both sides of the head end of the elastic insert 612 to form an effective transmission connection with the tooth groove of the passive snapping tooth 611, so that the passive rotating sleeve 608 will not slip during the process of separating the pulp by the pulp separating knife 601.

[0017] Example 2: Based on Embodiment 1, the present invention adds an elastic clamping component 5 to the side wall of the outer cone cylinder 301 to improve operational reliability. Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 14 , Figure 15 and Figure 16 As shown; The main body of the spindle 208 and the retaining seat 209 are both provided with a hexagonal sliding hole 502. The inclined platform 501 and the rotating seat 201 are coaxially fixed to the outer side of the vertical plate 102. The hexagonal sliding column 503 is slidably inserted into the hexagonal sliding hole 502. The inner stop block 504 is fixed to the inner end of the hexagonal sliding column 503. The tailstock 505 is fixed to the outer end of the hexagonal sliding column 503. The inner side of the tailstock 505 and the outer inclined surface of the inclined platform 501 form a sliding tangential fit. A tension spring 506 is sleeved on the outside of the hexagonal sliding column 503. One end of the tension spring 506 is fixed to the outer side of the vertical plate 102, and the other end is fixed to the tailstock 505. It can provide an elastic thrust toward the outer cone 301 side for the fixing mechanism formed by the tailstock 505, the hexagonal sliding column 503 and the inner stop block 504, so that the inner stop block 504 is always in an elastically extended state. Furthermore, the height of the inner stop 504 exceeds half of the orange after the hole is completed in the outer cone 301, and the elastic tension provided by the tension spring 506 is also set within a limited range, so that during the process of the orange being pierced into the insertion rod 303, the inner stop 504 can be pushed outward elastically without damaging the fruit shell, and after the hole is completed, the inner stop 504 can be held at a position more than half the height of the orange. After adding the elastic clamping component 5, it will not only not interfere with the central perforation of the orange, but also stabilize the main body of the orange during the process of digging holes at the ends after the perforation is completed. The method of removing the tangerine after the hole has been dug varies, and so does the use of the elastic clamping component 5. When using method one to directly remove the tangerine, before removal, to avoid damaging the fruit shell with the inner stop 504, the tail seat 505 needs to be gently pulled so that the inner stop 504 retracts to a position that does not interfere with the removal of the tangerine. When using method two, the corner frame 206 can be rotated directly. As the corner frame 206 rotates to the position where the positioning pin 211 elastically engages with the second positioning slot 204, and the outer cone 301 is in a state where the flared opening is facing down, the sliding tangential engagement between the tail seat 505 and the inclined platform 501 can just drive the inner stop 504 to retract inward to a position that does not affect the tangerine's gravity in falling. After that, under its own gravity, the tangerine with the hole dug falls downward into the receiving and limiting plate 103.
