Description

Technical Field

[0001] This utility model relates to the field of longan processing technology, specifically to a pulp receiving device for a longan peeling and pitting machine. Background Technology

[0002] In southern my country, longan, a widely cultivated and high-yielding fruit, has a highly seasonal harvest. Fresh longan has a short shelf life after ripening, making it crucial for farmers to quickly process it into dried longan. There are two methods for making dried longan. One method involves drying the longan fruit directly, shell and pit intact. This method produces dark brown, low-quality dried longan that is prone to insect infestation. Furthermore, drying the unproductive shell and pit together increases energy consumption. The other method involves peeling and pitting the fresh longan before drying the flesh. This method produces orange-yellow dried longan of better quality that is easier to preserve, thus increasing its value several times over compared to directly dried longan. It is indeed a beneficial method for both farmers and consumers. However, currently, peeling and pitting longan is done manually or by machine. Manual peeling is not only inefficient but also fails to meet hygiene requirements. Using a longan peeling machine to peel and pit longan improves production efficiency compared to manual peeling and pitting, while also meeting hygiene requirements. However, existing longan peeling machines directly collect the longan pulp, shell, and pit together after peeling and pitting, and then separate them later, which increases the workload and reduces work efficiency.

[0003] To address the aforementioned issues, an existing patent (publication number: CN212414639U) discloses a pulp receiving device for an automated longan peeling and pitting machine. However, this device is inconvenient to clean the pulp during the separation process, requiring an additional cleaning step. Furthermore, the device has a complex overall structure, is cumbersome to operate, and is inconvenient to use. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] The pulp receiving device of the longan peeling and pitting machine includes:

[0007] A base, on the inner wall of which an elastic rod is fixedly connected, and at the end of the elastic rod a screening box is fixedly connected. The screening box is arranged at an incline, and at the top of the base a feeding hopper is fixedly connected. The feeding hopper is located above the screening box.

[0008] A drive assembly is mounted on the side wall of the base and is used to drive the screening box to reciprocate.

[0009] The separation box is fixedly connected to the end of the base and is located below the screening box. Both sides of the separation box are provided with fruit peel collection grooves, and the fruit peel collection grooves are provided with drainage outlets.

[0010] The receiving tank is located inside the separation box. A reciprocating screw is rotatably connected inside the receiving tank. A moving rod is threaded onto the reciprocating screw. A scraper is rotatably connected below the moving rod. Elastic elements are fixedly connected to both sides of the scraper. The other end of the elastic element is connected to the moving rod.

[0011] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0012] When further processing of longan pulp is required, the product, after being processed by the shelling and pitting machine, enters the screening box directly through the hopper. Then, the first motor is started, driving the gear to rotate. The gear first meshes with the lower rack, moving the rack to the left. Under the rack's traction, the screening box moves to the left. Then, as the gear continues to rotate, it meshes with the upper rack, moving the rack to the right. Under the rack's traction, the screening box moves to the right. This process drives the screening box to reciprocate left and right. Because the sieve holes in the screening box are larger than the pits and smaller than the pulp, ... During screening, the fruit pits fall downwards into the base, thus separating the pulp from the pits. After removing the pits, the pulp and peel fall into the washing tank. At this point, the second motor is started, driving the reciprocating screw to rotate. Due to the meshing between the nut seat and the reciprocating screw, the nut seat moves left and right in a circular motion, which in turn moves the moving rod. The scraper then scrapes the peel floating on the water surface into the peel collection tanks on both sides, thus separating the pulp from the peel. After all the pulp has been separated, the water in the washing tank is drained, and the washed pulp is obtained.

[0013] In a preferred embodiment, the present invention can be further configured such that: the number of elastic rods is four, with each pair of elastic rods forming a group for coordinated use, and the two groups of elastic rods are respectively fixedly connected to both sides of the screening box.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the driving component includes a storage box fixedly connected to the side wall of the base, a missing gear is rotatably connected inside the storage box, and a first motor is fixedly connected to one side of the missing gear, and the first motor is fixed to the storage box;

[0015] Two mirror-arranged racks are fixedly connected to the side wall of the screening box. The racks pass through the base and the storage box, and the racks mesh with the gears.

[0016] In a preferred embodiment, the present invention can be further configured such that the center of the separation box is set as a washing tank, and two fruit peel collection tanks are located on both sides of the washing tank.

[0017] In a preferred embodiment, the present invention can be further configured such that: a nut seat is fixedly connected to the end of the moving rod, the nut seat is sleeved on the outside of the reciprocating lead screw and threadedly connected to the reciprocating lead screw, and the width of the nut seat is equal to that of the receiving groove.

[0018] In a preferred embodiment, the present invention can be further configured such that: a ball bearing is installed on the side wall of the moving rod away from the reciprocating lead screw, and a guide rail adapted to the ball bearing is provided on the top of the separation box on the side away from the reciprocating lead screw.

[0019] In a preferred embodiment, the present invention can be further configured such that a second motor is fixedly connected to one end of the reciprocating lead screw, and the second motor is fixed to the side wall of the separation box.

[0020] In a preferred embodiment, the present invention can be further configured such that arc-shaped grooves are provided on both sides of the scraper.

[0021] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0022] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0023] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0024] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0025] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0026] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0027] 1. This utility model, through the cooperation of the base, screening box, drive assembly and other structures, can achieve the separation of fruit pits, and the separated fruit pits will be collected uniformly for convenient subsequent processing. Furthermore, through the cooperation of the separation box, washing tank, reciprocating screw, scraper and other structures, not only can the peel be separated, but the pulp can also be washed, avoiding the need for additional washing procedures.

[0028] 2. This utility model has a simple overall structure and is easy to operate. It is not limited to processing longan but can also process other agricultural products, making it highly practical and promising for widespread application. Attached Figure Description

[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0036] Based on the concept of this application, combined with Figures 1 to 4This document describes an embodiment of a pulp receiving device for a longan peeling and pitting machine used to process longan pulp. Specifically, the pulp receiving device of this longan peeling and pitting machine is constructed as an integrated structure, comprising four components: a base 1, a drive assembly 5, a separation box 6, and a receiving tank 9. Through the cooperation of the base 1, the screening box 3, the drive assembly 5, and other structures, the pits can be separated, and the separated pits are collected uniformly for convenient subsequent processing. Furthermore, through the cooperation of the separation box 6, the washing tank 14, the reciprocating screw 10, the scraper 12, and other structures, not only can the peel be separated, but the pulp can also be washed, avoiding the need for additional washing steps.

[0037] Combination Figures 1-4 As shown, the pulp receiving device of the longan peeling and pitting machine provided by this utility model includes:

[0038] A base 1 has an elastic rod 2 fixedly connected to its inner wall. A screening box 3 is fixedly connected to the end of the elastic rod 2. The screening box 3 is arranged at an angle. A hopper 4 is fixedly connected to the top of the base 1. The hopper 4 is located above the screening box 3.

[0039] Drive assembly 5 is mounted on the side wall of base 1 and is used to drive screening box 3 to reciprocate.

[0040] Separation box 6 is fixedly connected to the end of base 1. Separation box 6 is located below screening box 3. Fruit peel collection troughs 7 are provided on both sides of separation box 6, and drainage outlets 8 are provided in fruit peel collection troughs 7.

[0041] The receiving groove 9 is located inside the separation box 6. A reciprocating screw 10 is rotatably connected inside the receiving groove 9. A moving rod 11 is threaded onto the reciprocating screw 10. A scraper 12 is rotatably connected below the moving rod 11. Elastic elements 13 are fixedly connected to both sides of the scraper 12. The other end of the elastic element 13 is connected to the moving rod 11.

[0042] It should be noted that the technical solution of this embodiment is mainly used to further process the pulp after the peeling and pitting machine. The hopper 4 is located at the discharge port of the peeling and pitting machine, so the product after the peeling and pitting machine is directly fed into the screening box 3 through the hopper 4.

[0043] In this embodiment, there are four elastic rods 2, with two elastic rods 2 forming a group for use. The two groups of elastic rods 2 are fixedly connected to both sides of the screening box 3. The elastic rods 2 provide support and reset function when the screening box 3 moves left and right for screening.

[0044] Regarding the technical solution of this embodiment, the driving component 5 includes a storage box 51 fixedly connected to the side wall of the base 1. A gear 52 is rotatably connected inside the storage box 51. A first motor 53 is fixedly connected to one side of the gear 52 and is fixed to the storage box 51. The first motor 53 is powered by an external power source. Two mirror-arranged racks 54 are fixedly connected to the side wall of the screening box 3. The racks 54 penetrate the base 1 and the storage box 51, and mesh with the gear 52. In actual use, starting the first motor 53 drives the gear 52 to rotate. When the gear 52 rotates, it selectively meshes with the two racks 54. For example, the gear 52 first meshes with the lower rack 54. 4. Engagement drives rack 54 to move to the left, and under the traction of rack 54, it drives sieve box 3 to move to the left. Then, as the missing gear 52 continues to rotate, it will engage with rack 54 above, driving rack 54 to move to the right, and under the traction of rack 54, it drives sieve box 3 to move to the right. In this way, sieve box 3 can be driven to reciprocate left and right. Since the sieve holes of sieve box 3 are larger than the pit and smaller than the pulp, the pit will fall downward into base 1 during sieving, thus achieving the separation of pulp and pit. It should be noted that the bottom plane of base 1 is inclined, and its inclination direction is opposite to that of sieve box 3. After the pit falls, it will roll along the inclined bottom plane and fall into the pre-prepared collection frame.

[0045] Regarding the technical solution of this embodiment, the center position of the separation box 6 is set as the washing tank 14, and two fruit peel collection tanks 7 are respectively located on both sides of the washing tank 14. The washing tank 14 is filled with clean water, and the pulp and peel falling from the sieve box 3 will enter the washing tank 14. Since the pulp is heavier than the peel, the pulp will gradually fall to the bottom of the washing tank 14, while the peel will float on the surface of the washing tank 14. The washing tank 14 can also be used to clean the pulp.

[0046] Regarding the technical solution of this embodiment, a nut seat is fixedly connected to the end of the moving rod 11. The nut seat is sleeved on the outside of the reciprocating lead screw 10 and threadedly connected to the reciprocating lead screw 10. The width of the nut seat is equal to that of the receiving groove 9. A second motor 15 is fixedly connected to one end of the reciprocating lead screw 10. The second motor 15 is fixed to the side wall of the separation box 6. The second motor 15 is powered by an external power source. After starting the second motor 15, it drives the reciprocating lead screw 10 to rotate. Due to the meshing action between the nut seat and the reciprocating lead screw 10, The nut seat moves left and right in a circular motion, which in turn moves the moving rod 11. At this time, the scraper 12 scrapes the fruit peel floating on the water surface into the fruit peel collection tanks 7 on both sides, thus separating the fruit pulp from the peel. After all the fruit pulp is separated, the water in the washing tank 14 is drained to obtain the washed fruit pulp. It should be noted that when scraping the peel, the water in the washing tank 14 will inevitably enter the fruit peel collection tank 7. At this time, the water can be drained using the drain outlet 8.

[0047] Furthermore, the end of the moving rod 11 away from the reciprocating screw 10 is located between the separation box 6 and the screening box 3, and a ball bearing is installed on the side wall of the end of the moving rod 11 away from the reciprocating screw 10. A guide rail adapted to the ball bearing is provided on the top of the side of the separation box 6 away from the reciprocating screw 10. The ball bearing and the guide rail are used to support the moving rod 11 and guide it when it moves.

[0048] Regarding the technical solution of this embodiment, arc-shaped grooves 16 are provided on both sides of the scraper 12, and a baffle is provided at the bottom of the arc-shaped grooves 16. When the scraper 12 moves in the clean water tank, the arc-shaped grooves 16 and the baffle can make the fruit peels located in the arc-shaped grooves 16. When the scraper 12 moves to the partition between the washing tank 14 and the fruit peel collection tank 7, the partition will squeeze the scraper 12 to deflect it, so that the fruit peels can be scraped into the fruit peel collection tank 7. Since the side of the baffle is rounded, the baffle will not interfere with the partition. In this way, the fruit peels can be removed in a cyclical manner.

[0049] It should be noted that there are four elastic elements 13, with two elastic elements 13 forming a group. The two groups of elastic elements 13 are located on both sides of the scraper 12. The elastic elements 13 are designed to keep the scraper 12 vertical when it moves in the water tank, and to prevent the scraper 12 from deflecting due to water resistance, thus preventing the fruit peel from being scraped off.

[0050] Specifically, when further processing of longan pulp is required, the product, after being processed by the shelling and pitting machine, enters the screening box 3 directly through the hopper 4. Then, the first motor 53 is started, driving the gear 52 to rotate. The gear 52 first meshes with the rack 54 below, causing the rack 54 to move to the left. Under the traction of the rack 54, the screening box 3 moves to the left. Then, as the gear 52 continues to rotate, it meshes with the rack 54 above, causing the rack 54 to move to the right. Under the traction of the rack 54, the screening box 3 moves to the right. In this way, the screening box 3 can be driven to reciprocate left and right. Because the sieve holes of the screening box 3 are larger than the fruit... Since the pit is smaller than the pulp, the pit will fall downwards into the base 1 during screening, thus separating the pulp from the pit. After removing the pit, the pulp and peel will fall downwards into the washing tank 14. At this time, the second motor 15 is started, which drives the reciprocating screw 10 to rotate. Due to the meshing between the nut seat and the reciprocating screw 10, the nut seat will move left and right in a circular motion, which will drive the moving rod 11 to move accordingly. At this time, the scraper 12 will scrape the peel floating on the water surface into the peel collection tanks 7 on both sides, thus separating the pulp from the peel. After all the pulp is separated, the clean water in the washing tank 14 is drained to obtain the washed pulp.

[0051] The pulp receiving device of the longan peeling and pitting machine provided by this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0052] The pulp receiving device of the longan peeling and pitting machine includes:

[0053] A base 1 has an elastic rod 2 fixedly connected to its inner wall. A screening box 3 is fixedly connected to the end of the elastic rod 2. The screening box 3 is arranged at an angle. A hopper 4 is fixedly connected to the top of the base 1. The hopper 4 is located above the screening box 3.

[0054] Drive assembly 5 is mounted on the side wall of base 1 and is used to drive screening box 3 to reciprocate.

[0055] Separation box 6 is fixedly connected to the end of base 1. Separation box 6 is located below screening box 3. Fruit peel collection troughs 7 are provided on both sides of separation box 6, and drainage outlets 8 are provided in fruit peel collection troughs 7.

[0056] The receiving groove 9 is located inside the separation box 6. A reciprocating screw 10 is rotatably connected inside the receiving groove 9. A moving rod 11 is threaded onto the reciprocating screw 10. A scraper 12 is rotatably connected below the moving rod 11. Elastic elements 13 are fixedly connected to both sides of the scraper 12. The other end of the elastic element 13 is connected to the moving rod 11.

[0057] The working principle and usage process of this utility model are as follows: When further processing of longan pulp is required, the product after being processed by the shelling and pitting machine first enters the screening box 3 directly through the hopper 4. Then, the first motor 53 is started to drive the gear 52 to rotate. The gear 52 first meshes with the rack 54 below, driving the rack 54 to move to the left. Under the traction of the rack 54, the screening box 3 moves to the left. Then, as the gear 52 continues to rotate, it meshes with the rack 54 above, driving the rack 54 to move to the right. Under the traction of the rack 54, the screening box 3 moves to the right. In this way, the screening box 3 can be driven to reciprocate left and right. The sieve openings are larger than the pits and smaller than the pulp. Therefore, during sieving, the pits fall downwards into the base 1, thus separating the pulp from the pits. After removing the pits, the pulp and peel fall downwards into the washing tank 14. At this time, the second motor 15 is started, which drives the reciprocating screw 10 to rotate. Due to the meshing between the nut seat and the reciprocating screw 10, the nut seat will move left and right in a circular motion, which will drive the moving rod 11 to move accordingly. At this time, the scraper 12 will scrape the peels floating on the water surface into the peel collection tanks 7 on both sides, thus separating the pulp from the peel. After all the pulp is separated, the clean water in the washing tank 14 is drained to obtain the cleaned pulp.
