Description

Technical Field

[0001] The invention relates to the technical field of apple processing equipment, and in particular to an apple conveying device for preventing apples from being damaged. Background Art

[0002] Apples are a fruit rich in various minerals and vitamins. They are widely favored by the public for their excellent nutritional value and have become an indispensable delicacy on the daily table. When the ripe season comes, apples need to be carefully picked and then quickly and safely transported to the processing plant. They undergo a series of fine treatments to ensure that they can be successfully marketed with exquisite packaging. In this series of production processes, the efficient conveying device plays a vital role. It not only greatly improves the processing efficiency of apples, but also ensures the smooth operation of the entire production line.

[0003] However, in the actual operation process, when the apples roll down the inclined plane from the highest point of the conveyor, the rolling speed gradually increases due to the acceleration of gravity until they reach the lowest point of the conveyor. The apples carry a large kinetic energy and directly collide with the bottom of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention effectively weakens the energy of apples sliding down the conveyor belt by setting a hollow deceleration rod, a deceleration roller, and a rubber sleeve, which work in coordination with a slide column, an upper circular magnet block, and a lower circular magnet block. When the apples slide down, the upper circular magnet block and the lower circular magnet block generate a weak repulsive force due to the repulsion of the same poles, so that the deceleration roller on the hollow deceleration rod slows down the speed of the apples sliding down and guides the apples to slide down steadily. The whole process reduces the risk of the apples being damaged by high-speed impact.

[0019] 2. The present invention uses air pump, cross pagoda joint, deceleration air box, air outlet, air guide cover and air guide of deceleration parts to accurately use air flow to further reduce the speed of apples hitting the deceleration roller. The air flow generated by the air pump is split through the cross pagoda joint, transported to the deceleration air box through the air guide structure, and blown out obliquely upward from the air outlet, forming resistance to the apple, slowing down the speed of its hitting the roller, and avoiding the situation where the apple is damaged by hitting the roller.

[0020] 3. The present invention provides a key buffering effect when the apple is about to reach the bottom of the conveyor belt by setting an inclined rod, a soft landing piece including an arc block and a hemispherical air cushion. When the apple is impacted, the soft landing piece rotates around the inclined rod, and the hemispherical air cushion is deformed under pressure, and works together with the telescopic spring to absorb the remaining kinetic energy of the apple, achieving a smooth landing. This design significantly reduces the impact force of the apple hitting the bottom of the conveyor belt, effectively reduces the damage to the apple, and improves the protection performance of the conveyor device.

[0021] 4. The present invention constructs a comprehensive side collision prevention system by arranging an air pump, a cross-shaped pagoda joint, a hollow rectangular positioning frame air duct, a hollow rectangular positioning frame, a hollow side collision prevention box, a side collision prevention hole, a side collision prevention branch pipe and a side collision prevention main pipe. The airflow is generated by the air pump, accurately distributed to the side collision prevention structure through the air duct, and ejected from the side collision prevention hole to form an air wall, which effectively reduces the collision between the apple and the side wall of the conveyor belt. At the same time, the air wall limits the movement trajectory of the apple, ensuring that the apple slides stably along the predetermined path, improving the stability and efficiency of the conveying process.

[0042] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0043] The present invention provides a technical solution:

[0044] See also Figures 1 to 8 An apple conveying device for preventing apples from being damaged is characterized in that it includes a conveyor belt 1 and a movable frame 2 fixedly installed at the bottom of the conveyor belt 1, the top of the conveyor belt 1 is symmetrically provided with mounting grooves, and the inner cavity of the mounting groove is provided with an energy unloading and deceleration mechanism 3, wherein the energy unloading and deceleration mechanism 3 can reduce the kinetic energy of the apple sliding to the lowest point of the conveyor belt 1, and can reduce the energy of the apple colliding with the lowest point of the conveyor belt 1, thereby achieving the effect of protecting the integrity of the apple.

[0045] A plurality of hollow rectangular positioning frames 301 are fixedly installed in the inner cavity of the mounting groove, a substrate 302 is fixedly installed in the inner cavity of the plurality of hollow rectangular positioning frames 301, a sliding column 303 fixedly installed in the inner cavity of the hollow rectangular positioning frame 301 passes through the substrate 302, an upper circular magnet block 304 located at the top of the inner cavity of the hollow rectangular positioning frame 301 is fixedly installed on the top of the sliding column 303, a lower circular magnet block 305 slidably connected to the sliding column 303 is arranged obliquely below the upper circular magnet block 304, and a speed reducer 306 slidably connected to the sliding column 303 is fixedly installed at the bottom of the lower circular magnet block 305.

[0046] When the apple slides down, the upper circular magnet block 304 and the lower circular magnet block 305 on the slide column 303 generate a repulsive force due to the repulsion of the same poles. Although it is not enough to prevent the apple from sliding down, it can reduce the speed at which the apple slides down on the conveyor belt 1. At the same time, the lower circular magnet block 305 slides up and down along the slide column 303 according to the size of the apple. In the case of slowing down the apple, it can also ensure that the apple passes through the deceleration member 306 normally. At the same time, it cooperates with the air flow deceleration measures to further reduce the impact force of the apple and effectively protect the apple from damage. This structure plays an important role in assisting deceleration and reducing the kinetic energy of the apple in the entire device.

[0047] A mounting frame 307 is fixedly installed at the bottom of the conveyor belt 1, an air pump 308 is fixedly installed on the mounting frame 307, a cross pagoda joint 309 is fixedly installed at the output end of the air pump 308, and an air guide structure 310 is fixedly installed at the air outlet end of the cross pagoda joint 309.

[0048] After the air pump 308 is started, the generated airflow is effectively diverted through the cross-shaped pagoda joint 309 and transported through the air guide structure 310. This design not only ensures the stable supply of airflow, but also realizes multiple deceleration protection for apples through the multi-directional use of airflow, effectively reduces the risk of damage to apples during transportation, and improves the overall performance of the transportation device.

[0049] The inner side of the conveyor belt 1 is symmetrically provided with an inclined rod 311 , and one end of the inclined rod 311 away from the conveyor belt 1 is rotatably connected to a soft landing piece 312 , and a telescopic spring 313 fixedly connected to the conveyor belt 1 is fixedly installed on the back of the soft landing piece 312 .

[0050] When the apple is about to reach the bottom of the conveyor belt, the soft landing member 312 rotates around the inclined rod 311 under the impact of the apple, and the telescopic spring 313 is deformed at the same time, and the two absorb the remaining kinetic energy of the apple together to play a buffering role. This design effectively reduces the impact force when the apple hits the bottom of the conveyor belt 1, reduces the damage to the apple, ensures that the apple lands smoothly, and improves the safety and protection of the conveyor device.

[0051] In some embodiments, the outer side of the slide column 303 and the inner circular surfaces of the lower circular magnet block 304 and the upper circular magnet block 305 are all provided with a polytetrafluoroethylene coating; the magnetic poles of the opposite surfaces of the lower circular magnet block 304 and the upper circular magnet block 305 are the same, and the shapes and sizes of the upper circular magnet block 304 and the lower circular magnet block 305 are exactly the same, and both are made of ferrite.

[0052] In this embodiment, the outer side of the slide column 303 and the inner surface of the upper circular magnet block 304 and the lower circular magnet block 305 are all provided with a polytetrafluoroethylene coating to reduce friction. When the apple slides, the upper circular magnet block 304 and the lower circular magnet block 305 repel each other with the same poles to generate a weak repulsive force, which slows down the speed of the apple. At the same time, due to the low magnetism and light weight of ferrite, it does not affect the normal sliding of the apple. The polytetrafluoroethylene coating further reduces friction and improves the durability of the device. This design effectively assists in deceleration, reduces the kinetic energy of the apple, and protects the apple from damage.

[0053] In some embodiments, the deceleration member 306 includes a hollow slip ring 3061, a hollow deceleration rod 3062 connected to the inner cavity of the hollow slip ring 3061 is fixedly installed on the outer cylindrical surface of the hollow slip ring 3061, a plurality of evenly distributed deceleration rollers 3063 are connected to the bearing on the hollow deceleration rod 3062, a rubber sleeve 3064 adapted to the deceleration roller 3063 is fixedly installed on the outer cylindrical surface of the plurality of deceleration rollers 3063, a deceleration air box 3065 connected to the inner cavity of the hollow deceleration rod 3062 is arranged between the two deceleration rollers 3063, the deceleration air box 3065 is fixedly connected to the hollow deceleration rod 3062, a plurality of air outlet holes 3066 are opened on the side of the deceleration air box 3065 facing the highest point of the conveyor belt 1, and an air guide cover 3067 located outside the air outlet holes 3066 is fixedly installed on the outer cylindrical surface of the deceleration air box 3065.

[0054] In this embodiment, when a number of apples slide down to the deceleration member 306 at the same time, they first contact the deceleration roller 3063. The energy generated by the apples in the process of falling along the conveyor belt 1 (mainly gravitational potential energy and kinetic energy, and other minor energies such as internal energy, elastic potential energy, etc. are ignored) will force the deceleration roller 3063 and the hollow deceleration rod 3062 connected thereto to move obliquely upward along the sliding column 303, while driving the hollow slip ring 3061 and the deceleration air box 3065 to move. The air pump 308 provides airflow to the inner cavity of the deceleration air box 3065, and the airflow is blown obliquely upward through the air outlet 3066, generating resistance to the apples, slowing down their sliding speed, and reducing the speed at which the apples collide with the deceleration roller 3063, thereby avoiding the situation where the apples are damaged due to the collision with the deceleration roller 3063. At the same time, the rubber sleeve 3064 on the outside of the deceleration roller 3063 is soft and elastic. When the apples collide with the rubber sleeve 3064, the possibility of damage to the apples can be reduced. The air guide cover 3067 guides the direction of the airflow to ensure the deceleration effect of the apples. This design effectively reduces the impact force of apples, reduces damage, protects the integrity of apples, and improves the safety and efficiency of the conveying device through the synergistic effect of mechanics and airflow (the energy generated during the apple's sliding is greater than the sum of the gravity of the speed reducer 306 and the repulsive force between the upper circular magnet block 304 and the lower circular magnet block 305).

[0055] In some embodiments, the air guide structure 310 includes two hollow rectangular positioning frame air guide tubes 3101 and a speed reducer air guide member 3102; one end of the hollow rectangular positioning frame air guide tube 3101 is fixedly connected to one of the air outlet ends of the cross pagoda joint 309, and the other end of the hollow rectangular positioning frame air guide tube 3101 is fixedly connected to the hollow rectangular positioning frame 301, and the hollow rectangular positioning frame air guide tube 3101 is connected to the inner cavity of the hollow rectangular positioning frame 301; the speed reducer air guide member 3102 includes a speed reduction main pipe 31021, one end of the speed reduction main pipe 31021 is fixedly connected to the remaining air outlet end of the cross pagoda joint 309, and the other end of the speed reduction main pipe 31021 is fixedly installed with a four-branch connecting pipe 31022, and the air outlet end of the four-branch connecting pipe 31022 is fixedly installed with a soft spring tube 31023 connected to the inner cavity of the hollow slip ring 3061.

[0056] In this embodiment, the air guide structure 310 plays a key role in air flow distribution. It includes two hollow rectangular positioning frame air guides 3101 and a deceleration member air guide 3102. The former connects the cross pagoda joint 309 with the hollow rectangular positioning frame 301, so that the air flow enters the anti-side collision structure 314 to form an air wall, reducing the collision between the apple and the side wall; the latter conveys the air flow to the deceleration wind box 3065 through the deceleration main pipe 31021, the four-branch connecting pipe 31022 and the soft spring tube 31023, providing power for the air blowing deceleration. The soft spring tube 31023 moves with the hollow deceleration rod 3062 to ensure a continuous supply of air flow. This design realizes the precise distribution and flexible adjustment of the air flow, which not only protects the apples from side wall collisions, but also slows down the sliding speed of the apples through air flow resistance, effectively reducing the risk of damage to the apples during transportation.

[0057] In some embodiments, the diameter of the air outlet end where the cross pagoda joint 309 is connected to the hollow rectangular positioning frame air guide tube 3101 is larger than the diameter of the air outlet end where the cross pagoda joint 309 is connected to the reduction main pipe 31021.

[0058] In this embodiment, when the airflow generated by the air pump 308 passes through the cross pagoda joint 309, more airflow is distributed to the hollow rectangular positioning frame air guide tube 3101, forming a stronger airflow barrier to protect the apples and reduce side wall collision. Less airflow is supplied to the deceleration air box 3065 through the deceleration main pipe 31021 to weaken the energy when the apples collide with the deceleration roller 3063, thereby achieving precise airflow distribution. This design ensures the stability and safety of the apples during transportation.

[0059] In some embodiments, the soft landing part 312 includes an arc block 3121 , and a plurality of evenly distributed hemispherical air cushions 3122 are fixedly mounted on the inner side of the arc block 3121 .

[0060] In this embodiment, when the apple is about to reach the bottom of the conveyor belt, the soft landing member 312 rotates around the inclined rod 311 under the impact of the apple, and the hemispherical air cushion 3122 contacts the apple and deforms under pressure, while the telescopic spring 313 deforms, absorbing the remaining kinetic energy of the apple and playing a buffering role. This design effectively reduces the impact force of the apple hitting the bottom of the conveyor belt 1, reduces the damage to the apple, and ensures that the apple lands smoothly.

[0061] See also Figure 1 to Figure 4 An anti-side collision structure 314 is arranged between the two hollow rectangular positioning frames 301. The number of the anti-side collision structures 314 is several. The anti-side collision structure 314 includes a hollow anti-side collision box 3141 fixedly installed between the two hollow rectangular positioning frames 301. The hollow anti-side collision box 3141 is located in the installation groove. A plurality of anti-side collision holes 3142 are opened on the hollow anti-side collision box 3141. A plurality of anti-side collision branch pipes 3143 connected to the inner cavity of the hollow anti-side collision box 3141 are fixedly installed on the top of the hollow anti-side collision box 3141. An anti-side collision main pipe 3144 located between the two hollow rectangular positioning frames 301 is fixedly installed at the air inlet end of the anti-side collision branch pipe 3143. The anti-side collision main pipe 3144 is connected to the inner cavity of the two hollow rectangular positioning frames 301.

[0062] The anti-side collision structure 314 is composed of a hollow anti-side collision box 3141 fixed between two hollow rectangular positioning frames 301, which has a built-in anti-side collision hole 3142 and is connected to the anti-side collision main pipe 3144 through the anti-side collision branch pipe 3143 to form an air flow channel. The airflow is distributed to each anti-side collision branch pipe 3143 through the anti-side collision main pipe 3144, and finally ejected from the anti-side collision hole 3142 to form an air wall. This air wall can effectively reduce the collision between the apple and the side wall of the conveyor belt during the sliding process, limit the movement trajectory of the apple, and ensure that the apple slides steadily. This design significantly reduces the risk of apple damage through the synergistic effect of physical barriers and airflow.

[0063] When in use, first start the air pump 308 to start generating airflow. These airflows are then effectively diverted through the cross pagoda joint 309, with one part of the airflow flowing along the hollow rectangular positioning frame air guide 3101, and the other part being transmitted through the speed reducer air guide 3102. The speed reducer air guide 3102 first passes through the speed reducer main pipe 31021, then through the four-branch connecting pipe 31022, and finally is transported to the hollow slip ring 3061 through the flexible soft spring tube 31023. This design allows the soft spring tube 31023 to be flexibly adjusted as the hollow speed reducer rod 3062 moves up and down, ensuring a continuous supply of airflow.

[0064] The diverted airflow enters the hollow rectangular positioning frame 301 and the hollow slip ring 3061 respectively. In the hollow rectangular positioning frame 301, the airflow is further distributed through the anti-side collision structure 314. Specifically, the airflow flows from the inner cavity of the hollow rectangular positioning frame 301 into the anti-side collision main pipe 3144, then enters the hollow anti-side collision box 3141 through the anti-side collision branch pipe 3143, and finally sprays out from the anti-side collision hole 3142 in the form of an air wall. Such a design can not only form a protective barrier during the sliding of apples, reduce the collision between apples and the side wall of the conveyor belt 1, but also limit the movement trajectory of apples to a certain extent, ensuring that apples can slide stably along the predetermined path.

[0065] At the same time, the airflow entering the hollow slip ring 3061 continues to flow to the hollow deceleration rod 3062, and enters the deceleration air box 3065 through it. In the deceleration air box 3065, the airflow is cleverly guided to the air outlet 3066, and blows obliquely upward along the inclined surface of the conveyor belt 1. When a number of apples begin to roll down from the highest point of the conveyor belt 1, they will first encounter the airflow ejected from the air outlet 3066. These airflows create resistance to the apples, effectively reducing their sliding speed, thereby reducing the energy of the apples when they hit the deceleration roller 3063.

[0066] When several apples slide down along the conveyor belt 1, they will eventually contact the deceleration roller 3063. Under the action of the energy generated in the process of the apples sliding along the conveyor belt 1, the deceleration roller 3063 and the hollow deceleration rod 3062 connected thereto will move obliquely upward along the slide column 303. In this process, although the upper circular magnet block 304 and the lower circular magnet block 305 have the same magnetic poles on the opposite surfaces and generate a certain repulsive force, since they are made of ferrite with low magnetism and light weight, this repulsive force is small and does not affect the normal sliding of several apples along the conveyor belt 1, but further reduces the sliding speed of the apples and weakens their energy, preparing for the apples to be transported to the lowest point of the conveyor belt.

[0067] In order to prevent the apples from colliding with the side wall of the conveyor belt 1 during the sliding process, the airflow ejected from the side collision prevention holes 3142 forms an air wall. This air wall not only reduces the possibility of the apples colliding with the side wall, but also protects the apples by providing additional buffering. At the same time, the air wall also limits the movement trajectory of the apples to a certain extent, making the transportation of the apples more stable and reliable.

[0068] When a number of apples are about to fall to the lowest point of the conveyor belt 1, the soft landing member 312 begins to work. When the apples contact the hemispherical air cushion 3122 on the arc block 3121, they are buffered. At the same time, the telescopic spring 313 also deforms to further absorb the remaining kinetic energy of the apples. The combined effect of the hemispherical air cushion 3122 and the telescopic spring 313 allows the apples to slide to the lowest point of the conveyor belt 1 at very low energy.

[0069] In summary, the apple conveying device that prevents apple damage effectively reduces the risk of apple damage during transportation through ingenious airflow design, magnet block assisted deceleration and the buffering effect of soft landing parts. This not only improves the processing efficiency of apples, but also ensures the overall quality and integrity of apples.

[0070] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
