Description

Technical Field

[0001] The invention relates to the technical field of blueberry conveyors, and in particular to an anti-accumulation blueberry conveyor for blueberry fruit production and application thereof. Background Art

[0002] Blueberry production conveyors are automated equipment designed specifically for blueberry picking, sorting, and transportation. They feature flexible conveying and gentle protection to prevent skin damage caused by collisions and squeezing. They typically utilize a food-grade stainless steel frame and non-toxic rubber and silicone conveyor belts. Common types include mesh belts, belts, and stepped conveyors. Stepped conveyors use staggered stepped baffles to create a buffer zone, allowing the blueberries to slide slowly down the steps during transportation, preventing stacking and squeezing. These conveyors are particularly suitable for transitioning from the picking platform to the sorting table due to height differences.

[0003] When conveying on the existing stepped conveyor, blueberries are easily stuck at the angle between the conveyor belt and the frame, causing damage to the blueberries. At the same time, when the blueberries enter the next conveyor belt, they have a certain vertical height, which can easily damage the blueberries. Moreover, when the blueberries pass through the conveyor belt mesh, if the blueberries pile up, it is easy to affect the screening effect. Therefore, we propose an anti-accumulation blueberry conveyor for blueberry fruit production and its application. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an anti-accumulation blueberry conveyor for blueberry fruit production and its application, comprising:

[0005] A bottom plate, the top of which is fixedly connected to a frame;

[0006] A conveying mechanism, wherein the conveying mechanism is fixedly connected to the interior of the frame, and the bottom of the conveying mechanism is fixedly connected to the top of the base plate;

[0007] Wherein, the conveying mechanism includes:

[0008] Conveyor belts, wherein three conveyor belts are provided inside the frame, and the three conveyor belts are distributed in a stepped manner, small holes are evenly distributed on the surface of the conveyor belts, and the apertures of the three conveyor belts gradually decrease along the conveying direction;

[0009] A drive assembly, the drive assembly is fixedly connected to the side of the frame, the drive assembly extends into the interior of the frame, and the drive assembly is drivingly connected to the three conveyor belts;

[0010] A buffer assembly is provided at a gap between two adjacent conveyor belts, the buffer assembly is slidably connected to the surface of the conveyor belt, and the side of the buffer assembly away from the conveyor belt is fixedly connected to the frame;

[0011] A blanking assembly, the blanking assembly is fixedly connected to the top of the base plate, three blanking assemblies are provided corresponding to the conveyor belt, the three blanking assemblies respectively extend into the interior of the corresponding conveyor belt, and the blanking assemblies are provided on the side of the conveyor belt away from the drive assembly;

[0012] Start the drive assembly, which drives the three conveyor belts to transport. The blueberry particles are placed on the top of the conveyor belts and transported along with the conveyor belts. During the transportation, blueberries smaller than the conveyor belt aperture pass through the small holes and then fall to the top of the unloading assembly, finally realizing unloading. The apertures of the three conveyor belts gradually decrease along the conveying direction, and the three conveyor belts are distributed in a stepped manner. While conveying, the blueberries can be naturally dispersed during the falling process to avoid accumulation. The blueberries are divided into different qualities according to the particle size and classified while being transported. The stepped conveyor belts have a certain vertical height. The buffer assembly is set at the interval of adjacent conveyor belts. It can provide buffering when the blueberries are transferred from one conveyor belt to another, avoiding the blueberries from being damaged by collision due to the influence of the vertical height, and avoiding affecting the quality of subsequent processed products.

[0013] Furthermore, the driving assembly includes a driving box, which is fixedly connected to a side of the frame away from the unloading assembly. The output end of the driving box is fixedly connected to a driving roller. The end of the driving roller away from the driving box passes through the frame and is rotatably connected to the inner side of the frame. There are three groups of driving rollers, and the three groups of driving rollers are respectively arranged inside the three conveyor belts. Each group of driving rollers is provided with two, and the two driving rollers are respectively arranged at both ends of the conveyor belt. The surface of the driving roller is transmission-connected to the inner side of the conveyor belt. The output end of the driving box drives the driving roller to rotate, and the driving roller drives the three conveyor belts to transmit, thereby finally realizing the transportation of blueberry fruits.

[0014] Furthermore, the inner side surface of the frame is fixedly connected with a side panel, and the side panels are provided with two, and the two side panels are symmetrically arranged with the conveyor belt as the center, and the sides of the two side panels close to each other are fixedly connected with a film, and the end of the film away from the side panel is arranged directly above the conveyor belt, and the film is inclined to the transmission direction of the conveyor belt, and a number of the films are evenly distributed on the surface of the side panels. When the conveyor belt drives the blueberries to be transported, the blueberries on the outermost side of the conveyor belt are at the angle between the frame and the conveyor belt. Under the action of friction, the blueberries may be damaged. By setting the film, when the blueberries are at the angle between the conveyor belt and the film, the film is squeezed by the blueberries and deformed. The squeezing force gradually disappears as the blueberries move, and the deformation of the film recovers, pushing the subsequent blueberries away from the angle to avoid damage to the blueberries at the angle. At the same time, the blueberries are pushed to the middle part with holes to ensure the screening effect. The film is tilted in the conveying direction, which can produce a smaller deformation angle, reduce the pushing force, and avoid damage to the blueberries caused by the pushing of the film. The blueberries are conveyed along the tilted direction of the film, which can also avoid the film hindering the conveyance of blueberries.

[0015] Furthermore, the buffer assembly includes an air hood, two of which are provided and arranged at the intervals between adjacent conveyor belts, the outer side surfaces of the air hoods being fixedly connected to the inner side surfaces of the frame, a branch pipe being provided just above the bottom plate, the two ends of the branch pipe being fixedly connected to the sides of the two air hoods away from the conveyor belts, a main pipe being fixedly connected to the side of the branch pipe close to the drive box, the end of the main pipe away from the branch pipe passing through the frame, and the outer side surface of the main pipe being fixedly connected to the inner side surface of the frame, driving the main pipe to generate suction, and the gas passes through the air hood, the branch pipe, and the main pipe in turn, generating suction for the blueberries that fall to the top of the next conveyor belt, thereby preventing the blueberries from being thrown away due to inertia, ensuring that the blueberries fall at the starting end of the conveyor belt, and ensuring the screening effect.

[0016] Furthermore, the end of the main pipe away from the branch pipe is fixedly connected to the pump body, the surface of the pump body is fixedly connected to the surface of the frame, and the end of the pump body away from the main pipe is fixedly connected to the exhaust pipe. When the pump body is started, the gas passes through the gas hood, branch pipe, main pipe, pump body, and exhaust pipe in sequence.

[0017] Furthermore, a buffer bar is provided on the side of the air hood away from the branch pipe, and both ends of the buffer bar are fixedly connected with a shovel plate, and the two shovel plates are slidably connected to the surfaces of the two conveyor belts on one side away from the buffer bar, and the side of the buffer bar close to the bottom plate is fixedly connected to the side of the air hood away from the bottom plate, and several buffer bars are provided at the interval between the two shovel plates, and the buffer bar is arranged in an arc shape and is made of rubber material. The shovel plate scoops up the blueberries and limits the blueberries to the interval between the two buffer bars under the action of suction. The suction force obtains sufficient pressure between the blueberries and the buffer bar, providing sufficient pressure for the rolling of the blueberries, so that the blueberries can roll down between the two buffer bars. The arc-shaped buffer bar has a longer rolling path, which can better dissipate the kinetic energy of the blueberries, so that when the blueberries fall on the top of the next conveyor belt, the position is further forward, so that the blueberries are evenly laid on the top of the conveyor belt as they are transported by the conveyor belt, thereby achieving better conveying and screening effects.

[0018] Furthermore, a column is provided on the side of the air hood away from the branch pipe, and there are several columns, and the columns pass through several buffer bars, and the surface of the column is fixedly connected to the inner side of the buffer bar. The several columns make it possible to enter fewer places when entering between two buffer bars, which can prevent blueberries from getting stuck between the buffer bars, and the several columns divide the opening of the air hood into several slits, which can increase the suction force and prevent the blueberries from being directly thrown away when entering the top of the next conveyor belt.

[0019] Furthermore, the blanking assembly includes a blanking plate, which is arranged inside the conveyor belt, and the blanking plate extends obliquely from the side of the driving box to the side close to the bottom plate, the surface of the blanking plate is fixedly connected to the frame, and the surface of the blanking plate is slidably connected to the surface of the driving roller, and a blanking frame is provided on the side of the blanking plate located outside the conveyor belt, and the blanking frame is arranged on the side of the blanking plate close to the bottom plate, the outer side surface of the blanking frame is fixedly connected to the mounting bracket, the side of the mounting bracket away from the blanking frame is fixedly connected to the top of the bottom plate, and the blanking frame is away from the bottom plate. The side is fixedly connected to the positive plate, and there are two positive plates, and the two positive plates are distributed in an eight-shaped shape. A V-plate is provided at the interval between the two positive plates, and the V-plate is fixedly connected to the side of the two positive plates close to each other. Blueberries smaller than the aperture enter the conveyor belt, fall to the top of the blanking plate, and then enter the blanking frame along the blanking plate to complete the blanking. The two positive plates distributed in an inverted eight-shaped shape can gather the blueberries, reduce the blanking range, and prevent the blueberries from being thrown around. The V-shaped V-plate can divert the gathered blueberries to avoid blockage caused by a large number of blueberries gathering in one place.

[0020] Furthermore, a blanking strip is fixedly connected to the inner side surface of the blanking frame, and several blanking strips are arranged below the blanking plate. The blanking strips are arranged in an arc shape, and the blanking strips are made of rubber material. The blueberries roll along the blanking plate and then fall to the top of the blanking strips. The blanking strips cushion the blueberries to avoid bumps when the blueberries are blanked. The blueberries roll along the intervals between the several blanking strips to separate the blueberries to avoid blockage of the blueberries inside the blanking frame. The arc-shaped blanking strips can bend along the arc curve when under pressure, so that the blanking strips evenly distribute the load and better cushion the blueberries.

[0021] An application of an anti-accumulation blueberry conveyor for blueberry fruit production comprises the following steps:

[0022] Step 1: Blueberry conveying: The output end of the drive box drives the drive roller to rotate, and the drive roller drives three conveyor belts to convey blueberries. The blueberry particles are placed on the top of the conveyor belts and conveyed along the conveyor belts. During the conveying process, blueberries smaller than the conveyor belt aperture pass through the small holes and then fall to the top of the discharge assembly.

[0023] Step 2: Move the blueberries. When the blueberries are at the angle between the conveyor belt and the film, the film is squeezed by the blueberries and deformed. The squeezing force gradually disappears as the blueberries move, and the film recovers its deformation, pushing the subsequent blueberries to the middle part with the hole.

[0024] Step 3: Blueberry buffering: Start the pump body, and the gas passes through the air hood, branch pipe, main pipe, pump body, and exhaust pipe in sequence, generating suction for the blueberries that fall to the top of the next conveyor belt. The shovel picks up the blueberries and, under the action of suction, limits the blueberries to the gap between the two buffer strips. The blueberries roll along the buffer strips, gradually consuming kinetic energy, so that the blueberries are evenly laid on the top of the next conveyor belt as they are transported by the conveyor belt;

[0025] Step 4: Blueberries are unloaded. Blueberries smaller than the hole diameter enter the conveyor belt and fall to the top of the unloading plate. Then they enter the unloading frame along the unloading plate. The blueberries roll along the unloading plate and then fall to the top of the unloading bar. The arc-shaped unloading bar bends along the arc curve to evenly distribute the load, cushion the blueberries, and finally complete the unloading.

[0026] The present invention has the beneficial effects:

[0027] 1. The present invention provides a conveying mechanism in which the apertures of the three conveyor belts gradually decrease along the conveying direction, and the three conveyor belts are distributed in a stepped manner. This allows the blueberries to naturally scatter during the falling process while being conveyed, thereby avoiding accumulation. The blueberries are classified into different qualities according to particle size and are classified while being conveyed. The stepped conveyor belts have a certain vertical height, and the buffer assembly is provided at the intervals between adjacent conveyor belts. This can provide buffering when the blueberries are transferred from one conveyor belt to another, thereby preventing the blueberries from being damaged by collisions due to the vertical height, thereby avoiding affecting the quality of subsequent processed products.

[0028] 2. The present invention provides a film. When the conveyor belt drives the blueberries to be transported, the blueberries on the outermost side of the conveyor belt are at the angle between the frame and the conveyor belt. Under the action of friction, the blueberries may be damaged. By providing the film, when the blueberries are at the angle between the conveyor belt and the film, the film is squeezed by the blueberries and deformed. The squeezing force gradually disappears as the blueberries move, and the deformation of the film is restored, so that the subsequent blueberries are pushed away from the angle to avoid damage to the blueberries at the angle. At the same time, the blueberries are pushed to the middle part with holes, which can ensure the screening effect. The film is inclined in the conveying direction, and the deformation angle is smaller, which reduces the pushing force and avoids damage to the blueberries caused by the pushing of the film. The blueberries are conveyed along the inclined direction of the film, which can also avoid the film hindering the conveyance of the blueberries.

[0029] 3. The present invention generates suction for blueberries that fall to the top of the next conveyor belt by providing a buffer component. The shovel scoops up the blueberries and, under the action of the suction, limits the blueberries to the gap between the two buffer bars. The suction creates sufficient pressure between the blueberries and the buffer bars, providing sufficient pressure for the rolling of the blueberries, so that the blueberries can roll between the two buffer bars. The arc-shaped buffer bars have a longer rolling path, which can better dissipate the kinetic energy of the blueberries, so that when the blueberries fall on the top of the next conveyor belt, they are positioned further forward, so that the blueberries are evenly laid on the top of the conveyor belt as they are conveyed, thereby achieving better conveying and screening effects.

[0030] 4. The present invention provides a plurality of columns, so that when entering between two buffer bars, there are fewer entry areas, which can prevent blueberries from getting stuck between the buffer bars. In addition, the plurality of columns divide the opening of the air hood into a plurality of slits, which can improve the suction force and prevent the blueberries from being directly thrown away when entering the top of the next conveyor belt.

[0031] 5. The present invention provides a feeding assembly with two positive plates in an inverted figure eight shape, which can gather blueberries, reduce the feeding range, and prevent blueberries from being thrown around. The V-shaped V-plate can divert the gathered blueberries to avoid a large number of blueberries gathering in one place and causing blockage. The feeding strips buffer the blueberries to avoid collisions when the blueberries are fed. The blueberries roll along the intervals between several feeding strips to separate the blueberries and prevent them from being blocked inside the feeding frame. The arc-shaped feeding strips can bend along the arc curve when under pressure, so that the feeding strips evenly distribute the load and better buffer the blueberries.

[0048] Among them, the conveying mechanism 3 includes:

[0049] Conveyor belts 31, three conveyor belts 31 are provided inside the frame 2, and the three conveyor belts 31 are distributed in a stepped manner, and small holes are evenly distributed on the surface of the conveyor belts 31, and the apertures of the three conveyor belts 31 gradually decrease along the conveying direction;

[0050] The drive assembly 32 is fixedly connected to the side of the frame 2 and extends into the interior of the frame 2. The drive assembly 32 is in transmission connection with the three conveyor belts 31.

[0051] The buffer assembly 33 is provided at the interval between two adjacent conveyor belts 31 , and the buffer assembly 33 is slidably connected to the surface of the conveyor belt 31 , and the side of the buffer assembly 33 away from the conveyor belt 31 is fixedly connected to the frame 2 ;

[0052] The blanking assembly 34 is fixedly connected to the top of the bottom plate 1. Three blanking assemblies 34 are provided corresponding to the conveyor belt 31. The three blanking assemblies 34 extend into the corresponding conveyor belt 31 respectively, and the blanking assemblies 34 are provided on the side of the conveyor belt 31 away from the driving assembly 32;

[0053] Start the drive component 32, which drives the three conveyor belts 31 to transport. The blueberry particles are placed on the top of the conveyor belt 31 and transported along with the conveyor belt 31. During the transportation, blueberries smaller than the aperture of the conveyor belt 31 pass through the small holes and then fall to the top of the unloading component 34, finally realizing unloading. The aperture of the three conveyor belts 31 gradually decreases along the conveying direction, and the three conveyor belts 31 are distributed in a stepped manner. While conveying, the blueberries can be naturally dispersed during the falling process to avoid accumulation. The blueberries are divided into different qualities according to the particle size and classified while being transported. The stepped conveyor belts 31 have a certain vertical height. The buffer component 33 is set at the interval of adjacent conveyor belts 31. It can provide buffering when the blueberries are transferred from one conveyor belt 31 to another conveyor belt 31, avoiding the blueberries from being damaged by collision due to the influence of the vertical height, thereby avoiding affecting the quality of subsequent processed products.

[0054] The driving assembly 32 includes a driving box 321, which is fixedly connected to the side of the frame 2 away from the blanking assembly 34. The output end of the driving box 321 is fixedly connected to a driving roller 322. The end of the driving roller 322 away from the driving box 321 passes through the frame 2 and is rotatably connected to the inner side of the frame 2. There are three groups of driving rollers 322, and the three groups of driving rollers 322 are respectively arranged inside the three conveyor belts 31. Each group of driving rollers 322 is provided with two, and the two driving rollers 322 are respectively arranged at both ends of the conveyor belt 31. The surface of the driving roller 322 is transmission-connected to the inner side of the conveyor belt 31. The output end of the driving box 321 drives the driving roller 322 to rotate, and the driving roller 322 drives the three conveyor belts 31 to transmit, thereby finally realizing the transportation of blueberry fruits.

[0055] The inner side surface of the frame 2 is fixedly connected with a side plate 323, and there are two side plates 323. The two side plates 323 are symmetrically arranged with the conveyor belt 31 as the center. The side of the two side plates 323 close to each other is fixedly connected with a film 324. The end of the film 324 away from the side plate 323 is arranged just above the conveyor belt 31, and the film 324 is inclined in the transmission direction of the conveyor belt 31. There are several films 324 evenly distributed on the surface of the side plate 323. When the conveyor belt 31 drives the blueberries to be transported, the blueberries on the outermost side of the conveyor belt 31 are at the angle between the frame 2 and the conveyor belt 31. Under the action of friction, the blueberries may be damaged. By setting the film 324, when the blueberries are at the angle between the conveyor belt 31 and the film 324, the film 324 is squeezed by the blueberries and deformed. The squeezing force gradually disappears as the blueberries move, and the deformation of the film 324 is restored, and the subsequent blueberries are pushed away from the angle to avoid damage to the blueberries at the angle. At the same time, the blueberries are pushed toward the middle part with holes, which can ensure the screening effect. The film 324 is inclined in the conveying direction, and the deformation angle is smaller, which reduces the pushing force and avoids damage to the blueberries caused by the pushing of the film 324. The blueberries are conveyed along the inclined direction of the film 324, which can also avoid the film 324 hindering the conveyance of the blueberries.

[0056] The buffer assembly 33 includes an air hood 331, two of which are provided, and the air hoods 331 are arranged at the intervals between adjacent conveyor belts 31. The outer side of the air hood 331 is fixedly connected to the inner side of the frame 2. A branch pipe 332 is provided just above the bottom plate 1. The two ends of the branch pipe 332 are respectively fixedly connected to the side of the two air hoods 331 away from the conveyor belt 31. The branch pipe 332 is fixedly connected to the side of the drive box 321 with a main pipe 333. The end of the main pipe 333 away from the branch pipe 332 passes through the frame 2, and the outer side of the main pipe 333 is fixedly connected to the inner side of the frame 2. The main pipe 333 is driven to generate suction. The gas passes through the air hood 331, the branch pipe 332, and the main pipe 333 in turn, generating suction for the blueberries that fall to the top of the next conveyor belt 31, preventing the blueberries from being thrown away due to inertia, ensuring that the blueberries fall at the starting end of the conveyor belt 31, and ensuring the screening effect.

[0058] A buffer bar 337 is provided on the side of the air hood 331 away from the branch pipe 332, and both ends of the buffer bar 337 are fixedly connected to a shovel plate 336. The sides of the two shovel plates 336 away from the buffer bar 337 are respectively slidably connected to the surfaces of the two conveyor belts 31, and the side of the buffer bar 337 close to the bottom plate 1 is fixedly connected to the side of the air hood 331 away from the bottom plate 1, and a plurality of buffer bars 337 are provided at the interval between the two shovel plates 336. The buffer bar 337 is arranged in an arc shape and is made of rubber material. The shovel plate 336 scoops up the blueberries and Under the action of suction, the blueberries are limited in the gap between the two buffer bars 337. The suction creates sufficient pressure between the blueberries and the buffer bars 337, providing sufficient pressure for the rolling of the blueberries so that the blueberries can roll down between the two buffer bars 337. The arc-shaped buffer bars 337 have a longer rolling path, which can better dissipate the kinetic energy of the blueberries, so that when the blueberries fall on the top of the next conveyor belt 31, the position is further forward, so that the blueberries are evenly laid on the top of the conveyor belt 31 as they are transported by the conveyor belt 31, achieving better conveying and screening effects.

[0059] A column 338 is provided on the side of the air hood 331 away from the branch pipe 332. There are several columns 338, and the columns 338 pass through several buffer bars 337. The surface of the column 338 is fixedly connected to the inner side of the buffer bar 337. The several columns 338 make it possible to enter fewer places when entering between two buffer bars 337, which can prevent blueberries from getting stuck between the buffer bars 337. The several columns 338 divide the opening of the air hood 331 into several slits, which can increase the suction force and prevent the blueberries from being directly thrown away when entering the top of the next conveyor belt 31.

A V-plate 345 is provided at the interval between the two positive plates 344, and the V-plate 345 is fixedly connected to the side of the two positive plates 344 close to each other. Blueberries smaller than the aperture enter the interior of the conveyor belt 31, fall to the top of the unloading plate 341, and then enter the unloading frame 342 along the unloading plate 341, and finally complete the unloading. The two positive plates 344 distributed in an inverted eight-shaped shape can gather the blueberries, reduce the unloading range, and prevent the blueberries from being thrown around. The V-shaped V-plate 345 can divert the gathered blueberries to avoid a large number of blueberries gathering in one place and causing blockage.

[0061] The inner side of the blanking frame 342 is fixedly connected with a blanking strip 346, and several blanking strips 346 are arranged below the blanking plate 341. The blanking strips 346 are arranged in an arc shape, and the blanking strips 346 are made of rubber material. The blueberries roll along the blanking plate 341 and then fall to the top of the blanking strips 346. The blanking strips 346 buffer the blueberries to prevent them from being bumped when being unloaded. The blueberries roll along the intervals between several blanking strips 346 to separate the blueberries and prevent them from being blocked inside the blanking frame 342. The arc-shaped blanking strips 346 can bend along the arc curve when under pressure, so that the blanking strips 346 evenly distribute the load and better buffer the blueberries.

[0062] An application of an anti-accumulation blueberry conveyor for blueberry fruit production comprises the following steps:

[0063] Step 1: Blueberry conveying: The output end of the drive box 321 drives the drive roller 322 to rotate, and the drive roller 322 drives the three conveyor belts 31 to convey blueberries. The blueberries are placed on the top of the conveyor belts 31 and conveyed along the conveyor belts 31. During the conveying, blueberries smaller than the aperture of the conveyor belts 31 pass through the small holes and then fall to the top of the discharge assembly 34.

[0064] Step 2: Move the blueberries. When the blueberries are at the angle between the conveyor belt 31 and the film 324, the film 324 is squeezed by the blueberries and deformed. The squeezing force gradually disappears as the blueberries move, and the deformation of the film 324 is restored, pushing the subsequent blueberries to the middle part with the hole.

[0065] Step 3: Blueberry buffering. Start the pump body 334. Gas passes through the air hood 331, branch pipe 332, main pipe 333, pump body 334, and exhaust pipe 335 in sequence, generating suction for the blueberries that fall onto the top of the next conveyor belt 31. The shovel plate 336 scoops up the blueberries and, under the action of the suction, confines the blueberries to the gap between the two buffer bars 337. The blueberries roll along the buffer bars 337, gradually consuming kinetic energy, so that the blueberries are evenly laid on the top of the next conveyor belt 31 as they are transported by the conveyor belt 31.

[0066] Step 4: Blueberries are unloaded. Blueberries smaller than the aperture enter the conveyor belt 31 and fall to the top of the unloading plate 341. Then, they enter the unloading frame 342 along the unloading plate 341. The blueberries roll along the unloading plate 341 and then fall to the top of the unloading bar 346. The arc-shaped unloading bar 346 bends along the arc curve to evenly distribute the load, cushion the blueberries, and finally complete the unloading.
