Description

Technical Field

[0001] The present invention relates to the technical field of pepper sorting, and more particularly to a sorting device and a pepper harvester using the same. Background Art

[0002] A pepper harvester is a piece of mechanical equipment specially used for pepper harvesting. It can improve harvesting efficiency and reduce manual labor intensity. The sorting device used in it can efficiently sort peppers according to size, color, shape and other characteristics, and can automatically remove stems, leaves, calyx and various foreign objects from peppers, effectively improving the quality and processing efficiency of peppers, reducing the impurity rate in pepper harvesting, and helping to reduce the cost of later fine processing.

[0003] During the on-site picking process of peppers, the external environment causes dew to often adhere to the surface of the peppers. When the pepper harvester collects a large number of small and dense peppers (such as millet peppers or chili peppers), although most of the stems and leaves can be removed during the harvesting stage, the residual wet leaves and soil crushed during the picking process are easy to adhere to the surface of the peppers. Although they enter the sorting device for further fruit and leaf separation, the treatment effect of such wet and sticky leaves and soil is not ideal. This situation not only reduces the accuracy of subsequent visual sorting and detection of peppers, but also increases the economic cost of fine processing.

[0004] To this end, the present application proposes a sorting device and a pepper harvester using the device to solve the above problems. Summary of the invention

[0005] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of the present invention is to provide a sorting device and a pepper harvester using the device, which solves the problem that peppers containing dew due to the external environment are easily adhered to residual wet leaves and dust on the surface when picked.

An intercepting net; a debris cleaning component, installed on the upper rear side of the separation bin, for clearing impurities from the intercepting surface of the intercepting net; a wind pressure component, installed on the top of the bin flow cover, for exhausting airflow using a rolling tower; the rolling tower is composed of a plurality of stacked conical tables, and the bottom widths of the plurality of conical tables increase layer by layer from top to bottom, and airflow strips are installed on the front and rear sides of the tops of the plurality of conical tables, and the airflow strips are connected to the central row pipe; a mounting plate is fixedly installed on the bottom end of the rolling tower, and frame grooves are provided on the left and right sides of the mounting plate, and adjacent mounting plates are separated by partitions, and the mounting plate and the partition are fixedly installed in the middle of the separation bin.

[0007] In a new embodiment, the vibration material assembly includes: a mounting table, installed at the upper front end of the separation bin; a shockproof frame plate, installed at the front end of the top end of the mounting table, and damping shock absorbers are also installed at the four corners of the bottom of the shockproof frame plate; an oblique wave plate, installed in the middle of the shockproof frame plate, and a vibrator is installed at the bottom, and the oblique angle of the oblique wave plate is 5 to 15 degrees.

[0008] In a new embodiment, the airflow component includes: an auxiliary plate installed at the lower front end of the separation bin; an air pump installed at the top of the auxiliary plate; a U-shaped exhaust pipe, one end of which is connected to the exhaust port of the air pump, and the other end of the U-shaped exhaust pipe is equipped with three branch pipes equidistantly installed on the transverse surface, the branch pipes pass through the front wall of the separation bin, and are all connected to the corresponding central exhaust pipes.

[0009] In a new embodiment, the debris cleaning component includes: a protection box, installed on the upper rear end of the separation bin; three electric telescopic rods, which are provided and all installed on the rear wall of the protection box; a collection box, the rear end of which is fixedly connected to the telescopic end of the electric telescopic rod, and a plurality of roller brush wheels are installed on the upper side of the collection box; an entry slot, which is opened at the rear of the bin flow cover, and the width is equal to the width of the collection box.

[0010] In a new embodiment, the wind pressure assembly includes: a top cover, which is installed on the top of the warehouse flow cover; three air collecting hoods are provided and are all installed on the top wall of the top cover; a delivery pipe, which is equidistantly installed on the top of the top cover, and one end is connected to the corresponding top of the air collecting hood; a gas booster, which is fixedly connected to the other end of the delivery pipe and is installed on the front of the warehouse flow cover.

[0011] In a new embodiment, the wind pressure assembly also includes: a transition wheel box, which is installed on the front upper side of the separation bin and has a feed port installed at the front; a feed blade shaft, which is rotatably installed in the middle of the transition wheel box; three discharge expansion ports, which are equidistantly installed at the rear end of the transition wheel box; and a top filter retention box, which is installed at the bottom of the transition wheel box.

[0012] In a new embodiment, the discharge expansion openings all penetrate the front upper side of the separation bin, and three drop openings are opened at the bottom of the discharge expansion openings, and the calibers of the drop openings increase successively from front to back.

[0013] In a new embodiment, three air supply channels are installed at the upper rear end of the transition wheel box, and one end of each of the air supply channels is connected to the corresponding gas booster exhaust port.

[0014] In a new embodiment, a discharge port is provided at the lower rear side of the separation bin, an inclined rolling plate is provided at the front of the discharge port, and the inclined rolling plate is installed at the lower inner side of the separation bin.

[0015] In a new embodiment, a pepper harvester includes a pepper harvester body and the above-mentioned sorting device.

[0016] Beneficial effect: Compared with the prior art, the advantage of the present invention is that by setting up a rolling tower, the peppers will roll along the slope of the rolling tower after falling. Since the rolling tower is composed of multiple conical platforms and the bottom width increases layer by layer, the peppers will fall and collide due to the height distance of the layers after rolling to each level. Combined with the airflow strips on the rolling tower, the rising airflow is released, so that the peppers under the action of collision and wind drying can remove surface dust and dry themselves, while small dust and the detached leaves will rise due to the blowing action of the upward wind force, and the interception net in the bin flow cover will effectively intercept impurities, further improving the quality of the sorted peppers.

[0017] By setting up an airflow component, the U-shaped exhaust pipe and the branch pipe are evenly and stably distributed to the central row pipe of each rolling tower, and discharged into the airflow strip through the central row pipe. The uniform airflow distribution helps the peppers to achieve more complete tumbling and separation in the rolling tower, thereby improving the uniformity and consistency of sorting.

[0018] By setting up a vibrating material assembly and utilizing the vibration of the oblique wave plate therein, the peppers are automatically arranged in rows during transportation, reducing the steps of manual sorting and thus improving the sorting efficiency. At the same time, the orderly arrangement also helps to improve the recognition accuracy and separation effect of subsequent sorting equipment.

[0019] By setting up a wind pressure component, the air flow discharged from the interception net is transmitted through an air collecting hood and a conveying pipe. The transmitted gas is pressurized by a gas booster to increase the air flow pressure, and is discharged into the transition wheel box through the air supply channel, providing driving force for the feed blade shaft in the transition wheel box to rotate, thereby achieving a relatively equal conveying effect for the transported peppers.

[0020] By setting a discharge expansion mouth and utilizing the graded drop openings thereon, the peppers can be separated and dropped in an orderly manner at the discharge expansion mouth. Since the diameter of the drop openings increases from front to back, it helps to guide the peppers to flow at a certain flow rate and direction, avoiding congestion and accumulation of the peppers during the discharge process, which is convenient for the subsequent hierarchical discharge of the peppers and also convenient for manual interception of peppers of different grades.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present application provides a sorting device and a pepper harvester using the device, thereby solving the problem that peppers containing dew due to the external environment are easily adhered to residual wet leaves and dust when they are picked. Although they are processed in the harvesting and sorting stages, the wet and sticky leaves and dust are still difficult to separate completely, affecting the subsequent visual sorting accuracy and finishing cost. When in use, the wet leaves and dust remaining on the surface of the peppers are sorted and processed, reducing the economic cost of finishing.

[0036] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows.

[0037] Example 1: Please refer to Figure 1-Figure 12, a sorting device includes a picking bin 1 and a conveying roller belt 2 installed at the front and rear parts thereof, and also includes: a separation bin 3 installed in the middle of the picking bin 1; a vibrating material component 4 installed on the upper front side of the separation bin 3, used for oscillating and arranging the picked peppers for conveying; three rolling material towers 5 are provided, and all are installed in the middle of the inner side of the separation bin 3; an airflow component 6 is installed on the lower front side of the separation bin 3, and is used to provide airflow supply for the rolling material tower 5; three central row pipes 7 are provided, all are installed in the middle of the rolling material tower 5, and are connected to the airflow component 6; a bin flow cover 8 is installed on the top of the separation bin 3, and an interception net 9 is installed inside it; a debris removal component 10 is installed on the separation bin The upper rear side of the separation bin 3 is used to remove impurities from the intercepting surface of the interception net 9; the wind pressure component 11, which is installed on the top of the bin flow cover 8, is used to discharge the airflow using the rolling tower 5; the rolling tower 5 is composed of a plurality of stacked conical platforms 12, and the bottom widths of the plurality of conical platforms 12 from top to bottom increase layer by layer, and airflow strips 13 are installed on the front and rear sides of the tops of the plurality of conical platforms 12, and the airflow strips 13 are connected to the central exhaust pipe 7; a mounting plate 14 is fixedly installed at the bottom end of the rolling tower 5, and a leak frame groove 15 is provided on the left and right sides of the mounting plate 14, and adjacent mounting plates 14 are separated by partitions 16, and the mounting plate 14 and the partition 16 are fixedly installed in the middle of the separation bin 3.

[0038] In this example, see Figure 1-Figure 12 As shown, the collected peppers are first conveyed into the vibrating material assembly 4 through the front conveying roller belt 2. The oscillation effect can effectively promote the uniform arrangement of the peppers during the conveying process. Then the peppers are conveyed and removed by the transition wheel box 115 in the wind pressure assembly 11. After completion, they are graded and discharged into the separation bin 3. The three rolling towers 5 in the separation bin 3 are used for wind removal. The impurity removal operation is as follows: First, the peppers are discharged to the top of the rolling tower 5 through the discharge expansion 118. After falling, the peppers roll along the inclined surface of the rolling tower 5. Since the rolling tower 5 is composed of multiple conical platforms 12 and the bottom width increases layer by layer, the peppers roll along the inclined surface of the rolling tower 5. After rolling to each level, it will fall and collide due to the height distance of the levels. Combined with the airflow strip 13 on the rolling tower 5, the rising airflow is released, so that the peppers can be dried by collision and wind drying. On the one hand, the surface dust is removed (the large amount of attached dust has been pre-treated by the transition wheel box 115), and on the other hand, the drying itself removes the attached wet leaves. The small dust and the detached leaves will rise due to the upward wind force, and the interception net 9 in the warehouse flow cover 8 will effectively intercept impurities. The impurities on the interception net 9 can be cleaned by the cleaning component 10, which further improves the quality of the sorted peppers.

[0039] Through the design of the rolling tower 5, the stacking structure of the conical table 12 is utilized, and the airflow provided by the airflow component 6 is combined to make the peppers tumble and separate in the rolling tower 5, which greatly improves the speed and efficiency of sorting. The entire sorting process has a high degree of automation, from the transportation, oscillation, tumbling and grading of the peppers to the interception and removal of impurities, which reduces the complexity and labor intensity of manual operations.

[0040] For further information, see Figure 5 and Figure 6 The airflow component 6 includes: an auxiliary plate 61, installed at the lower front end of the separation chamber 3; an air pump 62, installed at the top of the auxiliary plate 61; a U-shaped exhaust pipe 63, one end of which is connected to the exhaust port of the air pump 62, and the other end of the U-shaped exhaust pipe 63 is equidistantly installed on the horizontal surface with three branch pipes 64, the branch pipes 64 pass through the front wall of the separation chamber 3, and are all connected to the corresponding central exhaust pipe 7.

[0041] By setting up the airflow component 6, through the U-shaped exhaust pipe 63 and combined with the three equally spaced branch pipes 64, it is ensured that the airflow can be evenly and stably distributed to the central row pipe 7 of each rolling tower 5. This uniform airflow distribution helps the peppers to achieve more complete tumbling and separation in the rolling tower 5, thereby improving the uniformity and consistency of sorting. The air pump 62, as a power source, provides sufficient airflow for the entire airflow system. The strong airflow can not only drive the peppers to tumble quickly in the rolling tower 5, but also help remove attachments on the surface of the peppers, such as dust and leaves, further improving the sorting efficiency and the cleanliness of the peppers.

[0042] Example 2: Please refer to Figure 8 and Fig. 9 The vibration material assembly 4 includes: a mounting platform 41, which is installed at the upper front end of the separation bin 3; a shockproof frame plate 42, which is installed at the front end of the top of the mounting platform 41, and damping shock absorbers are also installed at the four corners of the bottom of the shockproof frame plate 42; an oblique wave plate 43, which is installed in the middle of the shockproof frame plate 42, and a vibrator is installed at the bottom, and the oblique angle of the oblique wave plate 43 is 5 to 15 degrees.

[0043] In this example, see Figure 8 and Fig. 9As shown, by setting up the vibration material assembly 4, firstly, the mounting table 41 is used as the basic supporting structure of the vibration material assembly 4 to ensure the stability and positioning accuracy of the entire vibration material assembly 4, and the function of the shockproof frame plate 42 is to further reinforce and support the oblique wave plate 43, and reduce the energy loss and noise during the vibration process, and secondly, damping shock absorbers are installed at the four corners of the bottom of the shockproof frame plate 42, which can effectively absorb and disperse the vibration energy to prevent the vibration from causing adverse effects on the separation bin 3 and other components, and the oblique wave plate 43 is the core component of the vibration material assembly 4, and a vibrator is installed at the bottom thereof. Driven by the vibrator, the oblique wave plate 43 can generate continuous vibration waves, and combined with the oblique angle setting of the oblique wave plate 43, it is helpful to guide the peppers to form an orderly arrangement during the transportation process, and promote the relative movement between the peppers, creating favorable conditions for subsequent sorting work.

[0044] Among them, the vibration effect of the oblique wave plate 43 can prompt the peppers to automatically arrange in rows during the transportation process, reducing the steps of manual sorting, thereby improving the sorting efficiency. At the same time, the orderly arrangement also helps to improve the recognition accuracy and separation effect of subsequent sorting equipment, and through the vibration effect, the attachments on the surface of the peppers (such as soil, dust, etc.) can be effectively removed, improving the cleanliness and sorting quality of the peppers. In addition, vibration also helps to separate impurities mixed in the peppers (such as pebbles, leaves, etc.), further improving the sorting effect.

[0045] Example 3: Please refer to Fig.12 The debris cleaning component 10 includes: a protection box 101, which is installed on the upper rear end of the separation bin 3; three electric telescopic rods 102 are provided and are all installed on the rear wall of the protection box 101; a collection box 103, the rear end of which is fixedly connected to the telescopic end of the electric telescopic rod 102, and a plurality of roller brush wheels 104 are installed on the upper side of the collection box 103; a bin entry slot 105 is opened at the rear of the bin flow cover 8, and the width is equal to the width of the collection box 103.

[0046] In this example, see Fig.12 As shown, by setting up the impurity cleaning component 10, the electric telescopic rod 102 is used to control the collection box 103 to quickly approach and move away from the interception net 9. Combined with the roller brush wheel 104 therein, the impurities on the interception net 9 can be rolled and cleaned, thereby avoiding the interference of impurities on the sorting process and ensuring the sorting accuracy and product quality. Among them, the collection box 103 makes the collection and cleaning of impurities convenient and quick. When the impurities in the collection box 103 accumulate to a certain extent, they can be easily taken out and cleaned, and then reinstalled back to the original position, which is also convenient for regular maintenance reminders of the sorting device.

[0047] Example 4: Please refer to Figure 8 , Fig.11 and Fig.12The wind pressure assembly 11 includes: a top cover 111, which is installed on the top of the warehouse flow cover 8; three air collecting hoods 112 are provided and are all installed on the top wall of the top cover 111; delivery pipes 113 are equidistantly installed on the top of the top cover 111, and one end is connected to the top of the corresponding air collecting hood 112; a gas booster 114 is fixedly connected to the other end of the delivery pipe 113, and is installed on the front part of the warehouse flow cover 8.

[0048] Furthermore, the wind pressure assembly 11 also includes: a transition wheel box 115, which is installed on the upper front side of the separation bin 3, and a feed port 116 is installed at the front; a feed blade shaft 117, which is rotatably installed in the middle of the transition wheel box 115; three discharge expansion ports 118 are provided and are equidistantly installed at the rear end of the transition wheel box 115; and a top filter retention box 119, which is installed at the bottom of the transition wheel box 115.

[0049] By setting up the wind pressure component 11, firstly, the air collecting hood 112 and the conveying pipe 113 are used to ensure that the airflow discharged through the interception net 9 is collected and transmitted more smoothly. The gas after transmission is further pressurized by the gas booster 114 to increase the airflow pressure, and is discharged into the transition wheel box 115 through the air supply channel 1111, and the discharge direction is aligned with the feed blade shaft 117, providing driving force for the feed blade shaft 117 in the transition wheel box 115, so that the feed blade shaft 117 rotates, ensuring that the amount of peppers in the trough of the oblique wave plate 43 is closer.

[0050] By providing the transition wheel box 115, the feeding blade shaft 117 and the discharge expansion port 118, firstly, the smooth transportation and discharge of the peppers are achieved, which helps to reduce the loss and blockage of the peppers during the transportation process, and improves the efficiency and stability of the pepper transportation. In addition, the top filter retention box 119 installed at the bottom of the transition wheel box 115 can remove impurities and fine particles in the peppers when the peppers are rotated and transported, thereby improving the quality of the discharged materials. This is particularly important for scenarios that require high-precision pepper sorting.

[0051] For further information, see Fig.10 The discharge expansion opening 118 passes through the upper front side of the separation bin 3, and three drop openings 1110 are opened at the bottom of the discharge expansion opening 118, and the calibers of the drop openings 1110 increase from front to back.

[0052] By setting a discharge expansion port 118 and utilizing the graded drop ports 1110 thereon, the peppers can be separated and dropped in an orderly manner at the discharge expansion port 118 (the discharge expansion port 118 is set obliquely). Since the diameter of the drop ports 1110 increases from front to back, it helps to guide the peppers to flow at a certain flow rate and direction, avoiding congestion and accumulation of the peppers during the discharge process. In addition, the drop ports 1110 of different diameters can be used for preliminary sorting according to the size of the peppers. Smaller peppers pass through the smaller diameter drop ports 1110 at the front end, while larger peppers pass through the larger diameter drop ports 1110 at the rear end. The peppers discharged first are first processed by the rolling tower 5, and the later ones are processed in the same way. This helps to distinguish the layers of the subsequent peppers and facilitates the manual interception of peppers of different grades.

[0053] For further information, see Fig.11 Three air supply channels 1111 are installed on the upper rear end of the transition wheel box 115 , and one end of the air supply channel 1111 is connected to the exhaust port of the corresponding gas booster 114 .

[0054] By setting up an air supply channel 1111, the high-pressure airflow generated by the gas booster 114 is directly sent into the transition wheel box 115 (a heating resistor can be added to the air supply channel 1111 to carry out wind heat flow, eliminate the wet state of the pepper, and provide pretreatment conditions for subsequent removal of leaves and dust). After the high-pressure airflow enters the transition wheel box 115 through the air supply channel 1111, it can form a forward thrust, pushing the pepper to move backward faster under the rotation of the feed blade shaft 117. This airflow-assisted conveying method can reduce the residence time of the material in the transition wheel box 115 and improve the efficiency of material conveying.

[0055] For further information, see Figure 4 and Fig.12 A discharge port is provided at the lower rear side of the separation bin 3, and an inclined rolling plate 17 is provided at the front of the discharge port. The inclined rolling plate 17 is installed at the lower inner part of the separation bin 3. By setting the inclined rolling plate 17, the peppers can be discharged through the discharge port faster under the action of gravity and rolling force, thereby improving the discharge efficiency, which is more effective for processing a large amount of peppers that need to be processed continuously and efficiently.

[0056] Example 5: The embodiment of the present application provides a pepper harvester, including a pepper harvester body, and the pepper harvester body is adapted to the sorting device described in Example 1.

[0057] Working principle: First, the peppers (such as chili peppers or chili peppers) collected by the pepper harvester are transported into the vibration material assembly 4 through the front conveyor roller belt 2, and driven by the vibrator installed at the bottom of the oblique wave plate 43 in the vibration material assembly 4, so that the oblique wave plate 43 can generate continuous vibration waves. Combined with the oblique angle setting and the trough shape of the oblique wave plate 43, it is helpful to guide the peppers to form an orderly arrangement during the transportation process. The peppers that have passed through the vibration material assembly 4 then gradually enter the transition wheel box 115 in the wind pressure assembly 11 for subsequent transportation and impurity removal. The ferry box 115, the feeding blade shaft 117 and the discharge expansion port 118 can realize the smooth transportation and discharge of the pepper, which helps to reduce the loss and blockage of the pepper during the transportation process. In addition, the top filter retention box 119 is installed at the bottom of the transition wheel box 115. Its filtering function can remove impurities and fine particles in the pepper when the pepper is rotated and transported, which reduces part of the burden for the subsequent discharge of pepper impurities. The pepper discharged through the feeding blade shaft 117 then passes through the discharge expansion port 118 connected to the transition wheel box 115, and the three drop ports 1110 opened on the discharge expansion port 118. , so that the peppers are discharged into the separation bin 3, and the rolling tower 5 in the three processing spaces separated from the separation bin 3 is used for wind decontamination. The wind decontamination process is that the peppers are discharged to the top of the rolling tower 5 through the discharge expansion port 118 and the drop port 1110, and then the peppers roll along the inclined surface of the rolling tower 5. Since the rolling tower 5 is composed of multiple conical platforms 12 and the bottom width increases layer by layer, after the peppers roll to each level, they will fall and collide due to the height distance of the levels. Combined with the airflow strips 13 on the rolling tower 5 to release the rising airflow, the peppers, due to the collision and wind drying, On the one hand, it removes dust on the surface, and on the other hand, it dries itself to remove wet leaves attached to it. Small dust particles and detached leaves will rise due to the blowing of upward wind force, and will be effectively intercepted by the interception net 9 in the bin flow cover 8 as impurities (wherein the wind source is provided by the airflow component 6, and the airflow discharged from the airflow component 6 by the rolling tower 5 will also act on the feed blade shaft 117 therein through the transmission and pressurization effect of the wind pressure component 11, thereby expanding the utilization effect of the wind force), and the impurities on the interception net 9 can be cleaned by the cleaning component 10, further improving the quality of the sorted peppers.
