A shock-absorbing and buffering sorting device for picking kiwifruit.

Abstract

This utility model relates to the field of kiwifruit sorting technology, specifically a shock-absorbing and buffering sorting device for kiwifruit harvesting. The advantages of this utility model are: kiwifruit are conveyed onto electric rollers with progressively increasing spacing. As the spacing increases, kiwifruit of different sizes fall into different sorting spaces according to their size, ultimately landing on the airbag cushion. The impact of the fall compresses the airbag cushion, causing it to contract and indent. This contraction absorbs the impact force, and combined with its inherent softness, prevents damage to the kiwifruit surface. Simultaneously, the indentation wraps around the bottom of the kiwifruit, stopping its sliding and slowing its movement. After the airbag cushion is impacted, the compressed air compresses the piston and enters the piston cylinder's inner wall. Simultaneously, after the impact, the piston is pushed back by the return spring, allowing gas to replenish the airbag cushion, thus reducing the rebound force and preventing the fruit from bouncing back.

Description

Technical Field

[0001] This utility model relates to the field of kiwi fruit sorting technology, and in particular to a shock-absorbing and buffering sorting device for kiwi fruit picking. Background Technology

[0002] Kiwifruit, a fruit rich in vitamin C and various nutrients, is highly favored in the market due to its unique taste and abundant nutritional value, leading to a rapid expansion of its cultivation scale. With the booming development of the kiwifruit industry, fruit harvesting and sorting have become crucial stages affecting its quality and economic benefits.

[0003] Most current sorting devices sort fruits by size through holes of different sizes. However, after sorting, the fruits fall directly into the collection device at the bottom. The impact of the falling fruits can easily damage the skin, affecting their appearance, and the wounds are prone to spoilage and decay. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a shock-absorbing and buffering sorting device for picking kiwifruit, which effectively solves the deficiencies of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution: A shock-absorbing and buffering sorting device for kiwifruit harvesting, comprising a support frame, a fixed frame fixedly connected to the top of the support frame, and a plurality of partition plates fixedly connected to the inner wall of the fixed frame, the partition plates dividing the inner wall of the fixed frame and the inner wall of the support frame into a plurality of sorting spaces, a plurality of electric rollers fixedly connected to each of the partition plates and to the inner wall of the fixed frame, the plurality of electric rollers being arranged in the plurality of sorting spaces according to different spacing, the spacing of the electric rollers in the plurality of sorting spaces being determined by the sorting space on one side. The sorting space gradually increases towards the other side. A vortex protrusion is fixedly connected to the outer wall of several electric rollers. An inclined support plate is fixedly connected to the inner wall of several sorting spaces on the side at the bottom of the fixed frame. An airbag is fixedly connected to the top surface of several inclined support plates. A piston cylinder is fixedly connected to the center of the bottom surface of several inclined support plates. A piston is slidably connected to the top of the inner wall of the piston cylinder. A reset thrust spring is provided between the bottom surface of the piston and the bottom surface of the inner wall of the piston cylinder. An exhaust hole is fixedly connected to the center of the bottom surface of the piston cylinder. The top of the piston cylinder communicates with the inside of the airbag.

[0006] Preferably, in any of the above schemes, the installation height of the small-pitch electric rollers inside the sorting space is greater than that of the large-pitch electric rollers, and the installation height of all the electric rollers is lower than the top surface of the fixed frame.

[0007] The technical effect achieved by adopting the above solution is that the fixed frame can intercept the kiwifruit from both sides to prevent it from slipping, while the kiwifruit is transported down in stages to prevent it from being blocked or interfered with.

[0008] Preferably, the dimensions of the inclined support plate are adapted to the dimensions of the inner wall of the sorting space, and the dimensions of the airbag cushion are adapted to the dimensions of the inclined support plate.

[0009] The technical effect achieved by adopting the above solution is that the inclined support plate and the airbag cushion can completely receive the kiwifruit falling from the sorting space.

[0010] Preferably, one side of the support frame is fixedly connected to a plurality of support baffles, the positions of the plurality of support baffles correspond to the positions of the plurality of sorting spaces, and a flip-over unloading plate is rotatably connected to one side of the top of each of the plurality of support baffles. One end of the flip-over unloading plate on the rotating side corresponds to the position of the bottom of the airbag cushion, and the width of the flip-over unloading plate is adapted to the width of the airbag cushion.

[0011] The technical effect achieved by adopting the above solution is that the kiwifruit slides down in segments as the airbag cushions slide, reducing the impact force during reception and minimizing damage to the kiwifruit.

[0012] Preferably, in any of the above embodiments, spring grooves are provided on both sides of the tilting unloading plate at positions corresponding to the rotation center. A supporting spring is fixedly connected to the inner wall of the spring groove. One end of the supporting spring is fixedly connected to a supporting baffle, and the other end of the supporting spring is fixedly connected to the inner wall of the spring groove. The tilting unloading plate remains horizontal under the action of the supporting spring.

[0013] The technical effect achieved by the above solution is that after receiving the kiwifruit, the tipping unloading plate stops the kiwifruit from falling further, and then slowly presses the tipping unloading plate down when there are too many kiwifruit, thereby slowing down the falling speed.

[0014] This utility model has the following advantages:

[0015] 1. This kiwi fruit harvesting shock-absorbing and sorting device uses several electric rollers rotating on their outer walls to move the kiwi fruit via vortex protrusions. As the fruit moves, it is transported onto the electric rollers with increasingly larger gaps. With the increased gaps, kiwis of different sizes fall into different sorting spaces according to their size, eventually landing on the airbag cushion. The impact of the fall compresses the airbag cushion, causing it to contract and indent. This contraction absorbs the impact, and combined with its inherent softness, prevents the kiwi fruit surface from being damaged by impact. At the same time, the indentation can wrap around the bottom of the kiwi fruit, stopping its sliding before it resumes sliding downwards as the airbag cushion returns to its original position, thus slowing down the sliding speed of the kiwi fruit, reducing the impact velocity, and improving the protective effect.

[0016] 2. The shock-absorbing and buffering sorting device for kiwi fruit harvesting compresses the piston by squeezing out the air after the airbag is impacted. The compressed air enters the inner wall of the piston cylinder. At the same time, after the impact ends, the piston is pushed back by the reset thrust spring, so that gas is replenished into the airbag and the airbag is reset. Meanwhile, the exhaust and intake speeds are restricted by the exhaust hole, thereby slowing down the rebound force and preventing the fruit from being bounced up. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 4As shown, a shock-absorbing and buffering sorting device for kiwi fruit harvesting includes a support frame 1. A fixed frame 2 is fixedly connected to the top of the support frame 1. Several partition plates 3 are fixedly connected to the inner wall of the fixed frame 2, dividing the inner wall of the fixed frame 2 and the inner wall of the support frame 1 into several sorting spaces. Several electric rollers 4 are fixedly connected to each other and to the inner wall of the fixed frame 2. The electric rollers 4 are arranged at different intervals within the sorting spaces, and the spacing of the electric rollers 4 within the sorting spaces gradually changes from one side of the sorting space to the other side. The outer walls of several electric rollers 4 are fixedly connected with vortex protrusions 5. The inner walls of several sorting spaces are fixedly connected with inclined support plates 9 on one side of the bottom position of the fixed frame 2. The top surfaces of several inclined support plates 9 are fixedly connected with airbags 6. The center of the bottom surface of several inclined support plates 9 is fixedly connected with piston cylinders 10. The top of the inner wall of piston cylinder 10 is slidably connected with pistons 11. A reset thrust spring 12 is provided between the bottom surface of piston 11 and the bottom surface of the inner wall of piston cylinder 10. The center of the bottom surface of piston cylinder 10 is fixedly connected with an exhaust hole 13. The top of piston cylinder 10 is connected to the inside of airbags 6.

[0024] As an optional technical solution of this utility model: the electric rollers 4 with small spacing inside the sorting space are installed at a higher height than the electric rollers 4 with large spacing. The installation height of the electric rollers 4 is lower than the top surface of the fixed frame 2, so that the fixed frame 2 can intercept the kiwifruit from both sides to prevent it from slipping. At the same time, the kiwifruit is conveyed down step by step to prevent it from being blocked or interfered with.

[0025] As an optional technical solution of this utility model: the size of the inclined support plate 9 is adapted to the size of the inner wall of the sorting space, and the size of the airbag 6 is adapted to the size of the inclined support plate 9, so that the inclined support plate 9 and the airbag 6 can fully receive the kiwifruit falling from the sorting space.

[0026] As an optional technical solution of this utility model: a plurality of support baffles 7 are fixedly connected to one side of the support frame 1. The positions of the plurality of support baffles 7 correspond to the positions of the plurality of sorting spaces. A flip-over unloading plate 8 is rotatably connected to one side of the top of each plurality of support baffles 7. One end of the flip-over unloading plate 8 on the rotating side corresponds to the position of the bottom of the airbag 6. The width of the flip-over unloading plate 8 is adapted to the width of the airbag 6, so that the kiwifruit sliding off the airbag 6 slides off in segments, reducing the impact force during receiving and reducing damage to the kiwifruit.

[0027] As an optional technical solution of this utility model: spring grooves 14 are provided on both sides of the flip unloading plate 8 at positions corresponding to the rotation center. A supporting spring 15 is fixedly connected to the inner wall of the spring groove 14. One end of the supporting spring 15 is fixedly connected to the supporting baffle 7, and the other end of the supporting spring 15 is fixedly connected to the inner wall of the spring groove 14. The flip unloading plate 8 remains horizontal under the drive of the supporting spring 15. With the support of the supporting spring 15, the flip unloading plate 8 prevents the kiwifruit from falling after receiving it. Then, when there are too many kiwifruit, the flip unloading plate 8 is slowly pressed down and slid down, thereby slowing down the sliding speed.

[0028] The working process of this utility model is as follows: When the user uses it...

[0029] 1) By rotating the outer wall of several electric rollers 4, the kiwi fruit can be conveyed and moved by the vortex protrusions 5. As it moves, the kiwi fruit is conveyed to the electric rollers 4 with the spacing constantly increasing. As the spacing increases, kiwi fruit of different sizes fall into different sorting spaces according to their size.

[0030] 2) The kiwi fruit eventually lands on the airbag cushion 6. The impact of the fall will compress the airbag cushion 6, causing it to contract and sink. This contraction can absorb the impact, and combined with its inherent softness, it can prevent the surface of the kiwi fruit from being damaged by the impact.

[0031] 3) At the same time, the indentation can wrap around the bottom of the kiwi, causing it to stop sliding first, and then slide downward as the airbag 6 resets, slowing down the sliding speed of the kiwi, reducing the impact speed, and improving the protective effect.

[0032] In summary, this invention utilizes the rotation of the outer walls of several electric rollers 4 to move kiwifruit via the vortex protrusions 5. As the kiwifruit moves, it is transported onto the electric rollers 4 with increasingly larger gaps. With these larger gaps, kiwifruit of different sizes fall into different sorting spaces according to their size, ultimately landing on the airbag cushion 6. The impact of the fall compresses the airbag cushion 6, causing it to contract and indent. This contraction absorbs the impact, and combined with its inherent softness, prevents damage to the surface of the kiwifruit. It can wrap around the bottom of the kiwi fruit, stopping it from sliding. Then, as the airbag 6 resets, it slides downwards, slowing down the kiwi fruit's sliding speed and impact speed, thus improving the protective effect. After the airbag 6 is impacted, the compressed air will compress the piston 11 and enter the inner wall of the piston cylinder 10. At the same time, after the impact ends, the piston 11 is pushed back to its original position by the reset thrust spring 12, allowing gas to replenish the airbag 6 and realize the reset of the airbag 6. Meanwhile, the exhaust and intake speeds are limited by the exhaust port 13, thereby slowing down the rebound force and preventing the fruit from bouncing back.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
