Description

Technical Field

[0001] This utility model relates to fruit seed sorting equipment, and in particular to an automated equipment for a high-efficiency areca nut seed sorting machine. Background Technology

[0002] Areca nut is one of the four major southern Chinese medicinal herbs and a popular fruit. However, the areca nut food manufacturing industry remains labor-intensive, with most processes requiring manual labor. Labor shortages and rising labor costs have become the biggest bottleneck to the industry's development. This creates an urgent need for automated areca nut food production.

[0003] Currently, the betel nut production process does not involve sorting, or mainly relies on manual sorting, which has many drawbacks, including the following:

[0004] First, without sorting, the areca nuts will be inconsistent in size and shape, affecting the uniformity of the final product. Second, manual sorting requires a large workforce, resulting in high costs; manual sorting capacity is low and cannot meet current production needs; manual sorting relies on workers' subjective judgment, leading to inconsistent sorting standards and unsatisfactory results. Utility Model Content

[0005] In order to solve the problems existing in the background technology, the present invention provides an automated equipment for high-efficiency areca nut seed sorting.

[0006] The technical solution adopted in this utility model is:

[0007] This utility model includes a feeding and spreading system, an infeed air separation and impurity removal system, a brush impurity removal system, a belt-type optical impurity removal system, a fruit sorting system, a sorting system, and a return system arranged on the production line; the feeding and spreading system for feeding areca nuts is arranged on the inlet side of the production line; the production line is divided into two layers, an upper layer and a lower layer, both of which are connected to the feeding and spreading system. The upper layer, from the inlet side to the outlet side, is arranged with the infeed air separation and impurity removal system, the brush impurity removal system, the belt-type optical impurity removal system, the fruit sorting system, and the sorting system in sequence, for performing multiple impurity removal and sorting of the areca nuts from the feeding and spreading system; the lower layer is arranged with a return system that completely covers the inlet side to the outlet side, and the return system contains a conveyor line for conveying the areca nuts falling from the outlet side of the production line back to the inlet side of the production line from the feeding and spreading system.

[0008] The feeding and feeding system includes a areca nut buffer hopper, a lifting and feeding conveyor belt, and scrapers; the lifting and feeding conveyor belt is arranged at an incline to transport the material from the bottom to the top; the areca nut buffer hopper is located at the bottom of the lifting and feeding conveyor belt and contains raw areca nut material; scrapers arranged at fixed intervals are provided on the surface of the lifting and feeding conveyor belt, and the scrapers are used to lift the areca nut material in the areca nut buffer hopper.

[0009] 3. The automated equipment for high-efficiency areca nut seed sorting as described in claim 2, characterized in that:

[0010] The feeding air separation and impurity removal system includes an impurity blowing device and a first impurity disk. The impurity blowing device is located at the top end of the lifting conveyor belt of the feeding and feeding system. It is used to receive the areca nut material conveyed by the lifting conveyor belt and then blow it to separate the impurities into the first impurity disk. The bottom of the impurity blowing device is provided with an impurity drop outlet and a material drop outlet. The first impurity disk is located directly below the impurity drop outlet and is used to receive impurities. A brush impurity removal system is arranged below the material drop outlet.

[0011] The impurity blowing device contains only an air blowing device. The air blowing device blows air onto the areca nut material coming out from the top end of the lifting conveyor belt in the opposite direction of the conveying. This causes the lighter particulate impurities in the areca nut material to be blown away to the impurity drop outlet, while the areca nut, heavier impurities and other fragmented impurities continue to be conveyed forward.

[0012] The brush-based impurity removal system includes a tumbling brush and a second impurity disc. The tumbling brush is located at the material drop outlet of the feed air separation impurity removal system, with gaps between the tumbling brushes. Below the gaps is a second impurity disc for receiving impurities. The tumbling brush is used to rotate and drive filamentous impurities such as nylon fibers mixed in the areca nut material, causing them to wrap around the tumbling brush and be peeled off, achieving the peeling effect. The tumbling brush is then cleaned periodically.

[0013] The belt-type optical impurity removal system includes an impurity removal vision device, a conveyor belt, an impurity blowing device, and a third impurity tray. The conveyor belt is arranged horizontally, with the inlet side of the conveyor belt located below the outlet of the feeding and distributing system. The impurity removal vision device is located above the middle of the conveyor belt, and its width covers the entire conveyor belt. The impurity blowing device is arranged above the outlet side of the conveyor belt, and the third impurity tray is arranged below the outlet side of the conveyor belt to receive the areca nuts blown away by the impurity blowing device.

[0014] There is a gap between the roller fruit tray conveyor line of the fruit sorting system and the conveyor belt of the belt-type optical impurity removal system. The impurity blowing device and the third impurity disk are respectively arranged above and below the gap. The areca nuts conveyed by the conveyor belt of the belt-type optical impurity removal system have an initial speed.

[0015] Without the impurity blowing device blowing, the betel nuts conveyed from the conveyor belt move in a parabolic motion after leaving the conveyor belt and onto the roller fruit tray conveyor line.

[0016] When the impurity blowing device is activated, the areca nuts conveyed from the conveyor belt are blown in the opposite direction, and then fall directly into the third impurity tray between the conveyor belt and the roller fruit tray conveyor line after leaving the conveyor belt and free falling.

[0017] The fruit sorting system includes a fruit sorting brush, a double-fruit air blowing device, and a roller fruit tray conveyor line. The roller fruit tray conveyor line is arranged horizontally. The inlet side of the roller fruit tray conveyor line is located below the outlet side of the conveyor belt of the belt-type optical impurity removal system (obliquely) and is arranged at intervals along the positive direction of areca nut material conveying. The fruit sorting brush and the double-fruit air blowing device are arranged sequentially at intervals along the positive direction of areca nut material conveying on the roller fruit tray conveyor line. The roller fruit tray conveyor line is equipped with roller fruit trays for holding areca nuts.

[0018] The sorting system includes a sorting vision device, a sorting air blowing device, and multiple fruit delivery conveyor lines. Fruit delivery conveyor lines are installed on both sides of the roller fruit tray conveyor line of the sorting system. Each fruit delivery conveyor line is horizontally arranged and perpendicular to the roller fruit tray conveyor line. The entrance side of the fruit delivery conveyor line is located below the roller fruit tray conveyor line. The sorting vision device is located on the roller fruit tray conveyor line, and the sorting air blowing device is installed on the entrance side of the fruit delivery conveyor line. Excess areca nuts that cannot be contained by the roller fruit tray conveyor line and the fruit delivery conveyor line fall from both sides into the lower-level return system.

[0019] The reflux system includes a reflux conveyor line and a reflux fruit air separation and impurity removal system. The reflux conveyor line is transported in the opposite direction to the areca nut material transport. The reflux conveyor line is horizontally arranged and runs through the lower layer of the entire production line. It reaches the feeding and spreading system from the roller fruit tray conveyor line of the fruit sorting system via the conveyor belt of the belt-type optical impurity removal system. The outlet end of the reflux conveyor line is connected to the reflux fruit air separation and impurity removal system via the lifting conveyor belt. The reflux fruit air separation and impurity removal system is arranged above the areca nut buffer hopper.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model enables large-scale continuous production of areca nut sorting, which can effectively and efficiently complete the sorting of areca nuts, thereby improving the uniformity and quality of the final product.

[0022] 2. This utility model equipment simultaneously completes the removal of impurities and sorting of areca nuts, shortening the steps in areca nut production.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] 【like Figure 1 and Figure 2 As shown, the equipment of this utility model includes a feeding and spreading system 1, a feeding air separation and impurity removal system 2, a brush impurity removal system 3, a belt-type optical impurity removal system 4, a sorting system 5, a sorting system 6, and a return system 7 arranged on the production line.

[0043] The inlet side of the production line is equipped with a feeding and spreading system 1 for feeding areca nuts. The production line is divided into two layers, an upper layer and a lower layer, both of which are connected to the feeding and spreading system 1. The upper layer, from the inlet side to the outlet side [along the direction of areca nut material transport], is equipped with a feeding air separation system 2, a brush removal system 3, a belt-type optical removal system 4, a fruit sorting system 5, and a sorting system 6, which are used to perform multiple removal and sorting of areca nuts from the feeding and spreading system 1 [the various systems are connected by conveyor lines]. The lower layer is equipped with a return system 7 that completely covers the inlet side to the outlet side. The return system 7 contains a conveyor line for transporting areca nuts falling from the outlet side of the production line back to the feeding and spreading system 1 at the inlet side of the production line.

[0044] The feeding and feeding system 1 includes a areca nut buffer hopper 11, a lifting and feeding conveyor belt 12, and a scraper 13; the lifting and feeding conveyor belt 12 is arranged at an angle towards the outlet side to transport the bottom material upwards to the top; the areca nut buffer hopper 11 is located at the bottom of the lifting and feeding conveyor belt 12 and contains raw areca nut material.

[0045] 【like Figure 3 As shown, scrapers 13 with fixed spacing are provided on the surface of the lifting conveyor belt 12 along the belt direction. The scrapers 13 are used to lift the areca nut material in the areca nut buffer hopper 11.

[0046] The raw material consists of areca nuts packed in woven bags, which are then released into the areca nut buffer hopper 11 of the feeding and cloth system 1. Some woven bag fragments or strips, as well as other miscellaneous fruits, remain on the hopper, which are removed or screened out during subsequent processing.

[0047] The feed air separation and impurity removal system 2 includes an impurity blowing device 21 and a first impurity disk 22. The impurity blowing device 21 is located at the top end of the lifting conveyor belt 12 of the feeding and spreading system 1. It is used to receive the areca nut material conveyed by the lifting conveyor belt 12 and blow it to separate a portion of the impurities into the first impurity disk 22. The bottom of the impurity blowing device 21 is provided with an impurity drop outlet and a material drop outlet. The first impurity disk 22 is located directly below the impurity drop outlet and is used to receive a portion of the impurities. A brush impurity removal system 3 is arranged below the material drop outlet. The material drop outlet is connected to the tumbling brush 31 of the brush impurity removal system 3.

[0048] The impurity blowing device 21 contains only a blowing device. The blowing device blows air onto the areca nut material coming out of the top end of the lifting and feeding conveyor belt 12 in the opposite direction of the conveying. This causes the lighter particulate impurities in the areca nut material (such as flower stems and leaves mixed in) to be blown away to the impurity drop outlet. The areca nut, heavier impurities and other fragment impurities continue to be conveyed forward.

[0049] 【like Figure 4As shown, the brush impurity removal system 3 includes a tumbling brush 31 and a second impurity disc 32. The tumbling brush 31 is located at the material drop outlet of the impurity blowing device 21 of the feed air separation impurity removal system 2. There are gaps between the tumbling brushes 31. A conveyor belt 42 is arranged below the tumbling brushes 31. A second impurity disc 32 is arranged below the gap to receive and receive another part of the impurities. The tumbling brush 31 is used to rotate and drive the filamentous impurities mixed in the areca nut material (such as nylon filaments or tying ropes of woven bags used for bagging areca nuts) to wrap around the tumbling brush 31, achieving the effect of peeling. Then the tumbling brush 31 is cleaned periodically.

[0050] 【【like Figure 4 As shown, the tumbling brush 31 has multiple brushes arranged at intervals, with gaps between adjacent brushes. The brushes continuously rotate, further processing the material screened by the impurity blowing device 21 of the feed air separation and impurity removal system 2. This causes the filamentous impurities to become entangled on the tumbling brush 31, achieving a peeling effect. The tumbling brush 31 is then cleaned periodically.

[0051] The belt-type optical impurity removal system 4 includes an impurity removal vision device 41, a conveyor belt 42, an impurity blowing device 43, and a third impurity disk 44. The conveyor belt 42 is arranged horizontally, with its inlet side located below the outlet of the feeding and spreading system 1 [and the tumbling brush 31 of the brush impurity removal system 3], [used to receive the areca nut material conveyed by the feeding and spreading system 1]. The impurity removal vision device 41 is located above the middle of the conveyor belt 42, and its width covers the entire conveyor belt 42. The impurity blowing device 43 is arranged above the outlet side [end] of the conveyor belt 42, and the third impurity disk 44 is arranged below the outlet side [end] of the conveyor belt 42, used to receive the areca nuts blown away by the impurity blowing device 43.

[0052] The impurity removal vision device 41 is used to detect the shape of the areca nuts and extract those with abnormal or irregular shapes. The impurity blowing device 43 is used to blow away and remove the areca nuts that have been detected as having irregular shapes by the impurity removal vision device 41, and blow them down to the third impurity tray 44.

[0053] There is a gap between the roller fruit tray conveyor line 53 of the fruit sorting system 5 and the conveyor belt 42 of the belt-type optical impurity removal system 4. The impurity blowing device 43 and the third impurity disk 44 are respectively arranged above and below the gap. The areca nuts conveyed by the conveyor belt 42 of the belt-type optical impurity removal system 4 have an initial speed when they leave.

[0054] Without the impurity blowing device 43 blowing, the areca nuts conveyed from the conveyor belt 42 move in a parabolic motion after leaving the conveyor belt 42 onto the roller fruit tray conveyor line 53.

[0055] When the impurity blowing device 43 is activated, the areca nuts conveyed from the conveyor belt 42 are blown in the opposite direction, and after leaving the conveyor belt 42, they fall directly into the third impurity tray 44 between the conveyor belt 42 and the roller fruit tray conveyor line 53.

[0056] 【like Figure 5 As shown, the fruit sorting system 5 includes a fruit sorting brush 51, a double-fruit air blowing device 52, and a roller fruit tray conveyor line 53. The roller fruit tray conveyor line 53 is arranged horizontally. The inlet side of the roller fruit tray conveyor line 53 is arranged diagonally below the outlet side of the conveyor belt 42 of the belt-type optical impurity removal system 4 and is spaced apart along the positive direction of areca nut material conveying. [In specific implementation, the outlet side of the roller fruit tray conveyor line 53 of the fruit sorting system 5 can be blocked.] The fruit sorting brush 51 and the double-fruit air blowing device 52 are arranged sequentially and spaced apart on the roller fruit tray conveyor line 53 along the positive direction of areca nut material conveying. The roller fruit tray conveyor line 53 is equipped with roller fruit trays 54 for accommodating areca nuts. Figure 6 As shown in the image.

[0057] In practice, the fruit sorting brush 51 is located above the front end of the roller fruit tray conveyor line 53, and the double fruit air blowing device 52 is located on the side of the roller fruit tray conveyor line 53 and behind the fruit sorting brush 51.

[0058] The fruit brush 51 is used to brush away excess areca nuts from the roller fruit trays 54 on the roller fruit tray conveyor line 53, so that each roller fruit tray 54 holds one areca nut. Excess areca nuts are blown off the roller fruit trays 54 on the roller fruit tray conveyor line 53 by the double fruit blowing device 52 and returned to the roller fruit tray return conveyor line 71.

[0059] In practice, multiple roller fruit tray conveyor lines 53 are arranged in parallel, and each roller fruit tray conveyor line 53 is equipped with a set of dual fruit air blowing device 52.

[0060] The sorting system 6 includes a sorting vision device 61, a sorting air blowing device 62, and multiple fruit delivery conveyor lines 63. Both sides of the roller fruit tray conveyor line 53 of the sorting system 5 are equipped with fruit delivery conveyor lines 63. Each fruit delivery conveyor line 63 is horizontally arranged and perpendicular to the roller fruit tray conveyor line 53. The entrance side of the fruit delivery conveyor line 63 is located below the roller fruit tray conveyor line 53 [and is connected along the direction perpendicular to the positive direction of areca nut material conveying]. The sorting vision device 61 is located on the roller fruit tray conveyor line 53 [used to visually inspect the length and other dimensional parameters of the areca nuts, as well as surface defects]. The sorting air blowing device 62 is installed on the entrance side of the fruit delivery conveyor line 63 [used to blow areca nuts of different sizes and those with surface defects onto the corresponding different fruit delivery conveyor lines 63 according to the detection results of the sorting vision device 61]. Excess areca nuts that cannot be contained on the roller fruit tray conveyor line 53 and the fruit delivery conveyor line 63 fall from both sides into the lower-level return system 7.

[0061] In practice, this includes multiple fruit delivery conveyor lines 63 and multiple roller fruit tray conveyor lines 53. Each fruit delivery conveyor line 63 is located below a roller fruit tray conveyor line 53, corresponding to different levels of areca nut landing points.

[0062] Each roller fruit tray conveyor line 53 is equipped with a sorting air blowing device 62, which is located on the side of the roller fruit tray conveyor line 53.

[0063] This invention features two vision devices, each used for different visual inspections: the belt-type optical impurity removal system 4's impurity removal vision device 41 is used to visually inspect crescent-shaped, Y-shaped, and other irregularly shaped areca nuts; the sorting system 6's sorting vision device 61 is used to visually inspect the areca nuts for dimensional parameters such as length and surface defects.

[0064] 【like Figure 7 and Figure 8 As shown, the reflux system 7 includes a reflux conveyor line 71 and a reflux fruit air separation and impurity removal system 72. The conveying direction of the reflux conveyor line 71 is opposite to the conveying direction of the areca nut material. The reflux conveyor line 71 is arranged horizontally and runs through the lower layer of the entire production line. The inlet end of the reflux conveyor line 71 is aligned with the outlet side of the roller fruit tray conveyor line 53 of the fruit sorting system 5. The material is conveyed from the roller fruit tray conveyor line 53 of the fruit sorting system 5 through the conveyor belt 42 of the belt-type optical impurity removal system 4 to the feeding and spreading system 1. The outlet end of the reflux conveyor line 71 is connected to the reflux fruit air separation and impurity removal system 72 via an inclined lifting conveyor belt. The reflux fruit air separation and impurity removal system 72 is arranged above the areca nut buffer hopper 11. The areca nut buffer hopper 11 is connected below the reflux fruit air separation and impurity removal system 72.

[0065] The lifting conveyor belt 12 of the lifting conveyor belt and the feeding and spreading system 1 are also arranged at an inclination, but in the opposite direction.

[0066] The areca nuts falling onto the return conveyor line 71 return to the bottom of the lifting conveyor belt via the return conveyor line 71. After being lifted by the lifting conveyor belt, they are transported to the return fruit air separation and impurity removal system 72. The return fruit air separation and impurity removal system 72 is equipped with an air blowing device that blows air in the opposite direction of the conveying of the areca nut material falling at the end of the lifting conveyor belt. This causes the lighter particulate impurities in the areca nut material to be blown away to the impurity falling outlet, and the areca nuts fall into the areca nut buffer hopper 11.

[0067] In this utility model, the areca nut buffer hopper 11 can buffer about 100kg of areca nut raw materials, and the scraper with a large angle, high density and low height can achieve uniform and thin distribution of the material.

[0068] The raw seeds are cleaned of light impurities (dust, flower stems, etc.) once by the impurity blowing device 21 of the feed air separation and impurity removal system 2.

[0069] The brush cleaning system 3 uses tumbling brushes 31 to filter through the brush gaps, removing light impurities (dust, flower stems, nylon bag filaments, etc.) and small-sized waste seeds from the raw seeds.

[0070] The raw seeds are cleaned in three ways using the impurity vision device 41 of the belt-type optical impurity removal system 4 (flower stem, large-sized defective seeds, and irregularly shaped defective seeds that affect the roller sorting).

[0071] The sorting vision device 61 of the sorting system 6 enables multi-view visual recognition, detection, and sorting of areca nut seeds.

[0072] The implementation process of this utility model is as follows:

[0073] Step 1: Pour the areca nuts from the woven bag into the areca nut buffer hopper 11. The areca nut buffer hopper 11 scatters the areca nuts onto the lifting and feeding conveyor belt 12. The cloth scraper 13 on the lifting and feeding conveyor belt 12 separates the areca nuts in batches and distributes them evenly on the lifting and feeding conveyor belt 12. Excess material is pushed out of the lifting and feeding conveyor belt 12 and falls into the return conveyor line 71. At this time, the material that falls into the return conveyor line 71 is returned to the areca nut buffer hopper 11 through the return fruit air separation and impurity removal system 72.

[0074] Step 2: The feeding air separation and impurity removal system 2 is connected to the end of the outlet side of the feeding conveyor belt 12. The areca nut material falls from the outlet side of the feeding conveyor belt 12. During the falling process of the areca nut material, the impurity blowing device 21 separates the areca nut fruit and some impurities by blowing air. Some impurities fall into the first impurity plate 22, and the remaining areca nut material falls into the tumbling brush 31 below.

[0075] Step 3: The tumbling brush 31 is set to a forward tilt angle, and there is a certain gap between the tumbling brushes 31. The tumbling brushes 31 continue to rotate, causing the areca nut material to rotate and move forward. This causes the nylon filaments and tying ropes that fall off when the woven bag is poured out to be wrapped around the brushes of the tumbling brush 31, and the inferior fruits with small stems and waists fall into the second impurity tray 32 below, while the qualified areca nuts fall into the conveyor belt 42.

[0076] Step 4: The areca nut material continues to move forward on the conveyor belt 42. The upper impurity removal vision system 41 identifies the remaining impurities and defective seeds in the areca nut material (the seeds are the areca nuts) and feeds the feedback to the impurity blowing system 43. The areca nut material falls at the end of the conveyor belt 42. The impurity blowing system 43 blows out the remaining impurities and defective seeds identified by the vision system 41, which fall into the lower third impurity tray 44. Qualified seeds fall into the fruit sorting device 51.

[0077] Step 5: The diversion hopper evenly distributes the areca nuts onto multiple parallel roller fruit tray conveyor lines 52. The areca nuts follow the rotation of the roller fruit trays 54 and fall into the roller fruit trays 54. The fruit brush 51 brushes off the top layer of stacked areca nuts. The areca nuts follow the roller fruit tray conveyor line 52 forward. The double fruit blowing device 53 located on one side blows the top layer of stacked areca nuts out of the roller fruit tray conveyor line 52 and blows them into the return conveyor line 71.

[0078] Step Six: The roller fruit tray conveyor line 52 extends to the sorting system 6. The sorting vision system 61 located above the roller fruit tray conveyor line 52 identifies betel nuts of different sizes and provides feedback to the sorting air blowing device 62. The sorting air blowing device 62 blows betel nuts of the same size into the same fruit discharge conveyor line 63 at a fixed point, while betel nuts of different sizes are blown into different fruit discharge conveyor lines 63. Each fruit discharge conveyor line 63 transports the betel nuts to its respective temporary storage bin.

[0079] Step 7: The areca nuts falling into the return conveyor line 71 are transported to the return fruit air separation and impurity removal system 72. After another air separation and impurity removal, they fall into the areca nut buffer hopper 11 of the feeding and spreading system 1 and enter the next cycle.

[0080] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.

[0081] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
