Description

Technical Field

[0001] The present invention relates to the field of berry picking, and more particularly to an automatic sorting device for shrub berries. Background Art

[0002] The berry industry in China is showing a rapid development trend and has great potential for future development. The existing berry harvesting methods mainly rely on manual labor and semi-automatic machinery. Semi-automatic machinery means that manual intervention is required to operate the equipment during picking. Currently, after the berries are picked, they are transported to the factory for manual sorting or sorting by other machines. This post-sorting method involves multiple links such as manual / machine handling, dumping, packing, and transportation jolts, which are extremely likely to cause extrusion, abrasion, and rupture, affecting the fruit quality and resulting in relatively large economic losses. Summary of the Invention

[0003] The present invention aims to provide an automatic sorting device for shrub berries to solve the problem that the berries are easily damaged during sorting by manual labor or other machines after picking.

[0004] To achieve the above object, the present invention adopts the following technical solution: An automatic sorting device for shrub berries, comprising: a conveying mechanism and a sorting mechanism. The conveying mechanism is used to convey the picked fruits to the sorting mechanism for screening; the sorting mechanism includes: a sorting storage body, a roller drive motor, a roller body, a feed inlet, a blower assembly, and a storage bin. The interior of the sorting storage body is hollow. The roller body is installed inside the sorting storage body. The roller drive motor is used to drive the roller body to rotate. The feed inlet is inclined. The lower end of the feed inlet communicates with the roller body. The air outlet of the blower assembly faces the feed inlet. The air outlet of the blower assembly is located above the lower end of the feed inlet, so that the air flow direction is opposite to the fruit feeding direction. The diameter of the sorting holes on the roller body gradually increases along its discharge direction. The storage bin is located below the roller body and is correspondingly arranged with the sorting holes.

[0005] Principle of this solution: The berries enter the feed inlet from the conveying mechanism. During the feeding process of the berries, due to the different masses of the branches and leaves and the fruits, their falling speeds are different, and the branches and leaves and the fruits will be separated during the feeding process. At this time, the blower assembly is turned on to blow air into the feed inlet, and the air flow will blow out the branches and leaves carried in the berries from the feed inlet to remove impurities from the berries; after impurity removal, the berries enter the roller body from the feed inlet. The roller drive motor drives the roller body to rotate. As the roller body rotates, the berry fruits are screened, and fruits of different particle sizes fall into the storage bin from the corresponding-sized sorting holes in sequence, completing the screening of the berry fruits.

[0006] Advantages of this solution: During the feeding process of berries, due to the different masses of branches and leaves and fruits, their falling speeds are different, so the branches and leaves and fruits will separate during the feeding process. By using the air duct assembly to blow air into the air inlet, the branches and leaves are blown away, cleaning the impurities in the berries. The air duct assembly can quickly remove impurities from the berries without contacting the berries and damaging them, with a fast separation speed. The sorting holes of different sizes on the roller body are used to screen fruits of different particle sizes, and various specifications can be screened without repeated screening, with high screening efficiency and a reduced fruit breakage rate. During the picking process, the conveying mechanism can be used to transport the fruits to the sorting mechanism for screening, preferably avoiding the problem of high fruit breakage rate caused by multiple transfers and sorting such as manual sorting or factory machine sorting after subsequent transportation. The screening efficiency is high and the fruit breakage rate is low.

[0007] Preferably, it further includes a cleaning assembly. The cleaning assembly includes a cleaning air duct and a cleaning fan. The cleaning fans are symmetrically arranged at both openings of the cleaning air duct. An air outlet is provided in the middle of the cleaning air duct, and the air outlet of the cleaning air duct faces the berries about to enter the feed inlet. The cleaning air duct and the cleaning fan are used to initially remove impurities from the berries, and at the same time, it also avoids the mutual influence of the branches and leaves blown out by the relatively arranged cleaning air duct assemblies, making the impurity removal effect of the berries better.

[0008] Preferably, dust-proof cover nets are provided at both ends of the cleaning air duct. The air first passes through the dust-proof cover nets for filtration and then enters the fan interior, reducing the entry of impurities into the cleaning air duct, avoiding affecting the impurity removal effect of the berries; at the same time, reducing the accumulation of impurities inside the cleaning air duct and the cleaning fan, and reducing the cleaning frequency.

[0009] Preferably, the air outlet of the cleaning air duct is flat-shaped. It can more effectively guide the air flow, reduce the turbulence and separation of the air flow, maintain the stability and continuity of the air flow, and enable the impurities to be separated more evenly.

[0010] Preferably, the air outlet of the cleaning air duct is located above the discharge end of the conveying mechanism. It can initially separate the branches and leaves from the berries at the end of the conveying mechanism, remove impurities from the berries, and ensure the quality of the picked berries.

[0011] Preferably, the air duct assembly includes: a power fan and a dust-removing air duct. The power fan is installed at the air inlet of the dust-removing air duct. The dust-removing air duct is fixedly installed on the top of the sorting storage body. The air outlet of the dust-removing air duct is flat-shaped. It can more effectively guide the air flow, reduce the turbulence and separation of the air flow, maintain the stability and continuity of the air flow, and enable the impurities to be separated more evenly.

[0012] Preferably, a storage box is provided in the storage bin, and a weighing mechanism for weighing the weight of the storage box is provided at the bottom of the storage bin. The weighing mechanism is used to weigh the storage box, so as to timely know whether the storage box is full, and timely replace the storage box to ensure the timely and continuous operation of the sorting mechanism and ensure the sorting efficiency. In this solution, the weighing mechanism is installed below the storage box.

[0013] Preferably, it further includes a buffer baffle and a moving mechanism for controlling the movement of the buffer baffle. The size of the buffer baffle matches the size of the storage box. By controlling the movement of the buffer plate, the opening at the top of the storage box can be controlled. At the same time, when the berries enter the storage box, the buffer plate can buffer the berries and reduce the damage of the berry fruits.

[0014] Preferably, the moving mechanism includes a rotating shaft and a motor for driving the rotating shaft to rotate. The motor is fixed on the inner wall of the sorting storage body, and the buffer plate is fixed on the rotating shaft. Using the motor to drive the buffer plate to rotate is simpler and easier to control.

[0015] Preferably, the conveying mechanism includes: a frame, a conveyor belt, a belt positioning column, a belt tensioning shaft, a drive shaft, and a motor for driving the drive shaft to rotate. The belt tensioning shaft and the drive shaft are installed on the frame. The belt tensioning shaft, the drive shaft, and the belt positioning column are used to make the conveyor belt rotate. The belt positioning column is located at the turning of the conveyor belt; the baffle is located at the edge of the conveyor belt. There are belt grooves on the conveyor belt, and the belt grooves are used to convey the berry fruits. The motor drives the drive shaft to rotate, the drive shaft makes the conveyor belt rotate, and then the drive shaft rotates. The conveyor belt rotates relative to the belt positioning column, and the belt positioning column guides the conveyor belt. The belt grooves are used to convey the berry fruits to prevent the berries from leaking out of the conveyor belt. The belt positioning column is set at the turning of the belt to prevent the belt from running off track and ensure the stable operation of the conveyor belt. Description of the Drawings

[0022] The following is a further detailed description through specific implementation manners: The reference signs in the accompanying drawings of the specification include: conveying mechanism 1, frame 11, belt tensioning shaft 12, conveyor belt 13, belt positioning column 14, belt groove 15, baffle plate 16, lifting motor 17, drive shaft 18, sorting mechanism 2, sorting storage body 21, roller drive motor 22, roller body 23, feed inlet 24, air duct assembly 25, power blower 241, impurity removal air duct 242, cleaning component 26, cleaning fan 261, cleaning air duct 262, storage bin 27, buffer plate 28.

[0023] Embodiment: An automatic sorting device for shrub berries, as Figure 1 shown, includes: a conveying mechanism 1 and a sorting mechanism 2. The conveying mechanism 1 is used to convey the picked fruits to the sorting mechanism 2 for screening.

[0024] The conveying mechanism 1 is as Figure 3 shown, and includes: a belt tensioning shaft 12, a frame 11, a conveyor belt 13, a belt positioning column 14, a belt groove 15, a baffle plate 16, a lifting motor 17, a speed reducer, a motion converter, and a drive shaft 18.

[0025] The belt tensioning shaft 12 is located at the feed end of the conveyor belt 13, and the drive shaft 18 is located at the discharge end of the conveyor belt 13. The lifting motor 17, the speed reducer, and the motion converter structure are used to drive the drive shaft 18 to rotate. The specific connection structure refers to the prior art. The output shaft direction of the lifting motor 17 is the same as the movement direction of the device, and a motion converter is used to change the direction of the output force of the motor. In this solution, the conveying mechanism 1 is used to lift and convey the fruits collected by the collection mechanism at the bottom of the corresponding picking device to the top, and then send them into the sorting mechanism 2 for sorting.

[0026] Among them, both the belt tensioning shaft 12 and the drive shaft 18 are installed on the frame 11. The specific installation method refers to the prior art and will not be described in detail here.

[0027] The conveyor belt 13 is located below the collection mechanism of the picking device and is correspondingly arranged with the discharge port of the collection mechanism. The conveyor belt 13 is provided with a belt groove 15 for separating and carrying the berries to prevent the berries from falling off the conveyor belt 13 during transportation. The belt positioning column 14 is arranged on the frame 11, and the belt positioning column 14 is arranged at the belt turning position to prevent the belt from running off track and ensure the stable operation of the conveyor belt 13. In this solution, the opening of the belt groove 15 faces the discharge direction of the conveyor belt 13, so that the berry fruits are located in the conveyor belt 13 during the upward movement of the conveyor belt 13.

[0028] Among them, the conveyor belt 13 is made of rubber material. When the berry fruits come into contact with the detailed surface, the rubber can evenly disperse the contact pressure, avoiding local stress concentration, bruising, and scratching caused by hard materials; the rubber deformation fits the outer surface of the fruit, more gently contacting and supporting the fruit, reducing damage to the fruit and the plant.

[0029] In this solution, the conveyor belt 13 includes a bottom horizontal feeding section, a lifting section, and a top horizontal discharging section. The berry fruits fall onto the bottom conveyor belt 13, then move upward through the lifting section to the top horizontal discharging section, and are then discharged from the top horizontal discharging section into the sorting mechanism 2. Specifically, the conveyor belt 13 can be set according to the berry collection port of the picking device. For example, if the berry collection port of the picking device is at the top, only the top horizontal discharging section conveyor belt 13 needs to be set for discharging.

[0030] A baffle plate 16 is provided on the frame 11. The baffle plate 16 is located at the edge of the conveyor belt 13 to prevent the berries from falling off the conveyor belt 13 and also block the branches, reducing the collision damage of the branches to the berries. The baffle plate 16 is located inside the frame 11, and the baffle plates 16 at the turning points of the conveyor belt 13 overlap each other to prevent the berry fruits from leaking out from the transition between the baffle plates 16. No baffle plate 16 needs to be set at the end of the conveyor belt 13, so that the berry fruits move relative to the conveyor belt 13 and fall off the conveyor belt 13 into the sorting mechanism 2.

[0031] Among them, the frame 11 is assembled from aluminum profiles and corner codes, and is fixedly connected by corner codes at the turning points.

[0032] Among them, the belt tensioning shaft 12 maintains the optimal belt tension through adjustable position changes, ensuring efficient power transmission and extending the system life. The conveyor belt 13 is driven to rotate through the belt tensioning pulley, the drive shaft 18, and the belt positioning column 14, driving the movement of the belt groove 15 to transport the berries.

[0033] After the berry fruits are picked, a part of the berry fruits directly make a free fall motion into the conveyor belt 13, and the other part of the fruits fall into the collection mechanism and then roll onto the conveyor belt 13. The fruits are sent to the sorting mechanism 2 through the conveyor belt 13 and are stored after sorting.

[0034] The sorting mechanism 2 is as Figure 2 、 Figure 4 and Figure 5 shown, and includes: a sorting and storage fuselage 21, a roller drive motor 22, a roller body 23, a feed inlet 24, a blower assembly 25, and a storage bin 27. In this solution, the sorting mechanism 2 is symmetrically arranged to facilitate the passage of the plant through the middle space.

[0035] The feed inlet 24 is inclined, and the lower end of the feed inlet 24 communicates with the drum body 23. The air duct assembly 25 is fixed on the sorting and storage body 21 of the machine, and the air outlet of the air duct assembly 25 faces the feed inlet 24, and the air outlet of the air duct assembly 25 is located at the lower end of the feed inlet 24. The conveying mechanism 1 conveys the berries into the feed inlet 24. During the feeding process of the berries, due to the different masses of the branches and leaves and the fruits, the falling speeds are different, and the branches and leaves and the fruits will be separated during the feeding process. The air duct assembly 25 is used to blow air towards the air inlet, so that the branches and leaves are blown away, and the impurities in the berries are cleaned up.

[0036] The air duct assembly 25 includes a power blower 241 and an impurity removal air duct 242. The air outlet of the impurity removal air duct 242 is flat-shaped, which can more effectively guide the air flow, reduce the turbulence of the air flow, maintain the stability and continuity of the air flow, and enable the impurities to be separated more evenly.

[0037] The interior of the sorting and storage body 21 is hollow. The drum body 23 is installed inside the sorting and storage body 21. The drum drive motor 22 is used to drive the drum body 23 to rotate. The drum drive motor 22 is installed on the sorting and storage body 21 through bearings. The diameter of the sorting holes on the drum body 23 gradually increases along its discharging direction. The storage bin 27 is located below the drum body 23, and the storage bin 27 is correspondingly arranged with the sorting holes. After the fruits enter the drum body 23, the drum drive motor 22 drives the drum body 23 to rotate. As the drum body 23 rotates, the fruits of different particle sizes fall into the storage bin 27 from the corresponding-sized sorting holes in sequence. Using the sorting holes of different sizes on the drum body 23 to screen the fruits of different particle sizes at one time, there is no need for repeated screening multiple times, and the screening efficiency is high and the fruit breakage rate is low. A cover plate fixed to the sorting and storage body is also provided above the drum body 23 to prevent the sundries blown by the fan from falling into the storage bin 27.

[0038] Among them, the drum drive motor 22 is installed on the sorting and storage body 21 through bearings. The sorting and storage body 21 is fixed on the outer shell of the corresponding picking mechanism through the mounting brackets. The mounting brackets are symmetrically arranged on the sorting and storage body 21, and the mounting brackets are welded and fixed to each other. The mounting brackets are fixedly connected to the outer shell of the picking mechanism by bolts or fixed by welding.

[0039] Among them, universal wheels are provided at the bottom of the sorting and storage body 21, which is convenient for moving the sorting and storage body 21.

[0040] Among them, the drum body 23 has a certain inclination angle. As the drum rotates, the fruits are sorted into five grades, and the sizes from small to large are 15mm, 18mm, 20mm, and 22mm respectively. The five-level sorting hole size grading is divided according to the size grade distribution of the berries. In addition, for different types of berries, the sorting module can be replaced according to the physical size, shape characteristics, etc. of the berries.

[0041] In this solution, the drum body 23 is inclined at 3° to the bottom surface of the sorting storage body 21. During the operation of the equipment, fruits enter the inside of the drum body 23. With the rotation of the drum body 23 and the self-weight of the fruits, the physical size grading is completed. After sorting, the fruits fall into the corresponding storage boxes. In addition, the drum is made of rubber material, with a moderate and adjustable rotation speed, effectively avoiding damage to the fruits by the machine.

[0042] Among them, the drum body 23 is made of rubber material, the edges of the sorting holes on its inner surface are smoothly transitioned, the rotation speed is moderate and adjustable, effectively avoiding damage to the fruits by the machine.

[0043] Among them, storage boxes are provided in the storage bin 27, and corresponding storage doors are provided on the side surface of the sorting storage body 21. The storage doors are used to take out the storage boxes, and the storage doors are provided with handles for facilitating the pulling out and replacement of the storage boxes. In this solution, the lower space of the drum body 23 in the sorting storage body 21 is the storage bin 27, and a partition can be set corresponding to the starting section of the change in the diameter of the sorting holes of the drum body 23 to divide the storage bin 27 into storage spaces for storing berries of different specifications.

[0044] In this solution, a weighing device is installed at the bottom below the storage bin 27. The weighing device is located at the bottom of the storage box, which can cumulatively weigh the fruits and feedback the relevant parameters to the corresponding human-computer interaction system and control system to remind to replace the storage bin 27. After sorting, the fruits fall into the storage bin 27 due to their own weight. As the berries are continuously picked and sorted, the storage boxes in the storage bin 27 are gradually filled with berries. At this time, only by replacing the corresponding storage box can the harvesting operation be continuously carried out. The weighing mechanism adopts existing technologies such as weighing sensors and will not be described in detail here.

[0045] Among them, a buffer baffle is provided at the top of the storage bin 27, and it matches the size of the top of the storage box. The number of buffer baffles is the same as that of the storage boxes. The buffer baffles are fixed on the rotating shaft, and the rotating shaft is fixedly connected to the output shaft of the motor installed on the inner wall of the sorting storage body 21. By controlling the rotation of the buffer plate 28, the opening at the top of the storage box is controlled. At the same time, when the berries enter the storage box, the buffer plate 28 can buffer the berries and reduce the breakage of the berry fruits.

[0046] A cleaning mechanism is also provided on the outer shell of the picking mechanism. The cleaning assembly 26 includes a cleaning air duct 262 and a cleaning fan 261, as Figure 6As shown in the figure, the cleaning fans 261 are symmetrically arranged at the two open ends of the cleaning air duct 262. An air outlet is provided in the middle of the cleaning air duct 262, and the air outlet of the cleaning air duct 262 faces the berries that are about to enter the feeding port 24. The cleaning air duct 262 and the cleaning fans 261 are used to preliminarily remove impurities from the berries. At the same time, it also avoids the mutual influence of the branches and leaves blown out by the relatively arranged air duct assemblies 25, making the impurity removal effect of the berries better. The air outlet of the cleaning air duct 262 is located above the discharge end of the conveying mechanism 1. The instantaneous cleaning of the fruits falling from the discharge port of the conveying mechanism 1 can preliminarily separate the branches and leaves from the berries at the end of the conveying mechanism 1, remove impurities from the berries, and ensure the quality of the picked berries. It also includes a motor fixing ring for fixing the motor. Dust-proof cover nets are provided at both ends of the cleaning air duct 262 to reduce the entry of impurities into the cleaning air duct 262.

[0047] Specific implementation process: The picked fruits are conveyed to the feeding port 24 by the conveyor belt 13. At the moment when the fruits fall from the discharge port of the conveyor belt 13, the cleaning air duct 262 removes the impurities that were not cleaned up in the previous stage for the second time. The feeding port 24 has a certain inclination angle. During the process of the fruits entering the feeding port 24, the impurity removal air duct 242 removes the impurities in the fruits again. The fruits slide to the roller body 23 by gravity. The roller drive motor 22 drives the roller body 23 to rotate. As the roller body 23 rotates, the berries inside it sequentially fall into the storage boxes below through the corresponding sorting holes. The weighing mechanism returns the weight data of the storage boxes. When the storage box is full, the buffer baffle is rotated to a position parallel to the ground of the sorting and storage body 21, and the feeding to the current storage box is stopped. Then the storage door is opened to replace the storage box.

[0048] In this solution, during picking, the conveying mechanism 1 is used to convey the fruits to the sorting mechanism 2 for screening, avoiding the low efficiency caused by traditional manual sorting and factory machine sorting after subsequent transportation, as well as the high fruit breakage rate caused by transportation and multiple sorting. The screening efficiency is high and the fruit breakage rate is low; the cleaning component 26 is used for primary impurity removal, and then the air duct component 25 is used for secondary impurity removal to ensure the impurity removal effect. At the same time, the cleaning component 26 further blows the impurities blown out by the air duct component 25 to avoid the mutual influence of the relatively arranged air duct components 25 and avoid affecting the impurity removal effect at the feeding port 24 of the sorting mechanism 2; the sorting holes of different sizes on the roller body 23 are used to screen fruits of different particle sizes. The aperture design of the sorting roller meets the sorting requirements of different berries, and can screen multiple specifications, avoiding the problems of low efficiency and high fruit breakage rate caused by multiple screenings; during the falling process of the berries, the air flow is used to remove impurities from the berries, without contacting the berries, without damaging the berries, and the separation speed is fast.
