Description

Technical Field

[0001] The utility model relates to the technical field of citrus processing, in particular to a citrus grading and packaging device. Background Art

[0002] With the increasing maturity of greenhouse cultivation technology, in addition to off-season vegetables, off-season fruits can also be grown in greenhouses. And because the sunlight time in the north is long, the temperature and humidity in the greenhouse can be controlled, and the growth environment is relatively independent, the quality of citrus is also better, and the transportation cost is greatly reduced. In general, the larger the citrus of the same variety, the higher the price. Especially for citrus grown off-season. The basic price itself is relatively high, and the price difference is even greater after size grading.

[0003] For the grading of citrus, the patent application number is 201610933005.9, and the name is "Online Conveying and Size Grading Equipment for Citrus Quality". The solution adopted is to use a machine vision system and an aperture principle tray, which can obtain information on the entire surface of the citrus, facilitating preliminary screening; at the same time, the size of the holes at the bottom of the aperture principle tray can be freely and continuously changed, which can be applied to all sizes to ensure the accuracy of grading; and with the ring guide rail, the device can be recycled, improving the efficiency of grading. However, the grading of citrus by continuously changing the size of the holes at the bottom of the aperture principle tray has high requirements for the aperture tray, and the grading speed of citrus is slow. Summary of the invention

[0004] In view of this, it is necessary to provide a citrus grading and packaging device with a simple structure, efficient grading and easy packing.

[0005] A citrus grading and packaging device includes a buffer trough, a lifting conveyor belt, a horizontal sorting conveyor belt, an inclined sorting chute, a citrus sorting slide, and a citrus packaging workbench. The end of the buffer trough is adjacent to the bottom of the lifting conveyor belt, the top of the lifting conveyor belt is adjacent to the horizontal sorting conveyor belt, so that the citrus conveyor belt is transported to the horizontal sorting conveyor belt, the end of the horizontal sorting conveyor belt is adjacent to the upper end of the inclined sorting chute, the lower part of the inclined sorting chute is connected to the citrus sorting slide, the sorted citrus falls onto the citrus sorting slide, the end of the citrus sorting slide is adjacent to the citrus packaging workbench, so that the citrus is guided to the citrus packaging workbench; the inclined sorting chute is provided with a plurality of sorting troughs distributed in parallel and in a fan shape, the spacing between the sorting troughs gradually increases from the top to the bottom, and the citrus gradually falls from the sorting trough from small to large.

[0006] Preferably, a plurality of scrapers are evenly distributed on the surface of the lifting conveyor belt, the scrapers are perpendicular to the surface of the lifting conveyor belt, and the height of the scrapers is 5 to 12 centimeters.

[0007] Preferably, the citrus sorting slide is provided with at least two guide grooves, the tail ends of which gradually shrink, so that the sorted citrus can enter the citrus packaging workbench in sequence.

[0008] Preferably, the guide trough includes a collecting section, an arc-shaped guide section, and a contraction section. The collecting section is located directly below the inclined sorting chute. The end of the collecting section is connected to the arc-shaped guide section. The arc-shaped guide section is inclined downward along the direction of the arc-shaped guide section so that the citrus can fall smoothly into the arc-shaped guide section. The arc-shaped guide section guides the citrus to change from lateral movement to longitudinal movement.

[0009] Preferably, the citrus packaging workbench includes a supporting platform and a limiting frame. The upper end of the supporting platform is connected to the limiting frame. The limiting frame is provided with a plurality of limiting grooves. The width of the limiting grooves is the same as the width of the outlet of the guide groove. The citrus tray is placed directly below the limiting grooves.

[0010] Preferably, a plug plate is provided at the end of the limiting frame to control the entry and exit of the citrus tray.

[0011] Beneficial effect: When the citrus grading and packaging device of the utility model is used, the picked citrus are first poured into the buffer tank, and then the citrus in the buffer tank is lifted to the horizontal sorting conveyor belt by the lifting conveyor belt. When the citrus is on the horizontal sorting conveyor belt, the bad and deformed fruits are manually picked out, and then the citrus is transferred to the inclined sorting chute. Under the action of gravity, as the citrus rolls, the citrus with a small diameter falls first, and the citrus with a large diameter falls later, so that the citrus of different sizes can be graded according to the distance of rolling. Since a number of sorting troughs are distributed in parallel on the inclined sorting chute, multiple citrus can be sorted at the same time. With the transportation of the lifting conveyor belt and the horizontal sorting conveyor belt, the utility model can sort a large number of citrus, and compared with the prior art, the sorting efficiency can be significantly improved. After the citrus is sorted, it falls from the citrus sorting chute to the citrus packaging workbench for rapid packaging, thereby locking the moisture of the citrus and preventing the citrus from drying out due to untimely packaging. At the same time, through the packaging of citrus packaging workbench, the rapid spread of subsequent citrus spoilage to surrounding citrus can be slowed down, thereby reducing the storage and transportation losses of citrus and improving the quality of citrus.

DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0017] Please see Figures 1 to 3 A citrus grading and packaging device includes a buffer trough, a lifting conveyor belt, a horizontal sorting conveyor belt, an inclined sorting chute, a citrus sorting slide, and a citrus packaging workbench. The end of the buffer trough is adjacent to the bottom of the lifting conveyor belt, and the top of the lifting conveyor belt is adjacent to the horizontal sorting conveyor belt to transport the citrus conveyor belt to the horizontal sorting conveyor belt. The end of the horizontal sorting conveyor belt is adjacent to the upper end of the inclined sorting chute. The lower part of the inclined sorting chute is connected to the citrus sorting slide. The sorted citrus falls onto the citrus sorting slide. The end of the citrus sorting slide is adjacent to the citrus packaging workbench to guide the citrus into the citrus packaging workbench; the inclined sorting chute is provided with a plurality of sorting troughs distributed in parallel and in a fan-shaped distribution. The spacing between the sorting troughs gradually increases from the top to the bottom, and the citrus gradually falls from the sorting trough from small to large.

[0018] The buffer slot of the utility model is used to place the citrus fruits that have been picked. Since the picking basket contains a lot of citrus fruits, it is impossible to immediately transport them through the lifting conveyor belt. The buffer slot can quickly receive a large number of citrus fruits in the picking basket for buffering, so that the lifting conveyor belt gradually consumes the citrus fruits in the buffer slot.

[0019] The lifting conveyor belt of the utility model is used to lift the citrus in the buffer tank. In order to facilitate the dumping of the citrus, the buffer tank is set relatively low, and the citrus needs to roll down with the help of gravity during the subsequent sorting, and the starting position of the citrus sorting needs to be relatively high. Therefore, the lifting conveyor belt is required to first lift the citrus in the buffer tank to a certain height.

[0020] In a preferred embodiment, a plurality of scrapers are evenly distributed on the surface of the lifting conveyor belt, the scrapers are perpendicular to the surface of the lifting conveyor belt, and the height of the scrapers is 5 to 12 centimeters.

[0021] The scraper is used to scrape the citrus in the buffer tank onto the lifting conveyor belt and prevent the citrus from rolling back into the buffer tank due to gravity during the upward conveying process. When the height of the scraper is 5-12 cm, the citrus will rarely pile up in front of the scraper, and only one to two rows of citrus can be scraped at a time. This prevents congestion in the subsequent sorting of citrus due to excessive conveying of citrus.

[0022] The horizontal sorting conveyor belt of the utility model is used to convey and sort citrus horizontally. During the picking process, the state of the citrus is not carefully observed, and there may be citrus that have been rotten or infested by insects or pecked by birds. If these citrus are not picked out in time, they will quickly rot and infect the surrounding citrus. At the same time, there may also be citrus that are deformed and do not meet the packaging requirements. The citrus can be sorted by the horizontal sorting conveyor belt, so as to reduce the quality problems that occur in the subsequent storage and transportation of citrus.

[0023] The inclined sorting chute of the utility model is used to grade citrus fruits according to their sizes. The inclined sorting chute is provided with a plurality of sorting troughs which are arranged in parallel and in a fan-shaped distribution, and the spacing between the sorting troughs gradually increases from the top to the bottom. After the citrus fruits enter the inclined sorting chute, the citrus fruits with smaller diameters first fall onto the citrus sorting chute and are closer to the starting point of the inclined sorting chute, and the citrus fruits with larger diameters fall onto the citrus sorting chute later and are farther from the starting point of the inclined sorting chute, thereby separating the citrus fruits of different sizes.

[0024] The citrus sorting chute of the utility model is used to guide the graded citrus to the citrus packaging workbench for packaging. The height difference between the inclined sorting chute and the citrus packaging workbench is large. Directly falling from the inclined sorting chute to the citrus packaging workbench may cause the inside of the citrus to be squeezed, thereby causing it to rot faster. The citrus sorting chute can reduce the impact force during the transition process of the citrus.

[0025] In a preferred embodiment, the citrus sorting slide is provided with at least two guide grooves, the tail ends of which gradually shrink, so that the sorted citrus can enter the citrus packaging workbench in sequence.

[0026] The packaging box of citrus can have multiple rows or one row per layer, but in the embodiment of the utility model, if multiple rows are placed on each layer, it is necessary to manually arrange the plates, which takes a lot of time. The utility model shrinks the guide groove so that the citrus can only roll out of the guide groove one by one. In this way, there is no need for manual arrangement, and only needs to roll them sequentially into the foam tray of citrus. After the foam tray is full of citrus, it can be removed. Accordingly, the utility model is more suitable for packaging boxes with only one row per layer.

[0027] The sorting of citrus is generally carried out on the roadside. The roadside is characterized by a long length but limited width. The citrus grading and packaging device of the utility model needs to maintain a slender structure as much as possible. Therefore, in a preferred embodiment, the guide trough includes a collecting section, an arc-shaped guiding section, and a contraction section. The collecting section is located directly below the inclined sorting chute, and the end of the collecting section is connected to the arc-shaped guiding section. The arc-shaped guiding section is inclined downward along the direction of the arc-shaped guiding section so that the citrus can fall smoothly to the arc-shaped guiding section. The arc-shaped guiding section guides the citrus to change from lateral movement to longitudinal movement.

[0028] Furthermore, the arc-shaped guiding section and the contraction section may be combined to gradually contract the width during the arc-shaped guiding process.

[0029] The arc-shaped guide section can change the sliding direction of the citrus, so that the citrus is changed from sliding horizontally to sliding longitudinally, so that the citrus grading and packaging device can maintain a slender structure.

[0030] In a preferred embodiment, the citrus packaging workbench includes a supporting platform and a limiting frame. The upper end of the supporting platform is connected to the limiting frame. The limiting frame is provided with a plurality of limiting grooves. The width of the limiting grooves is the same as the width of the outlet of the guide groove. The citrus tray is placed directly below the limiting grooves.

[0031] The support platform is used to place the citrus tray. The citrus tray is generally provided with round holes to prevent the citrus from rolling in the packaging box. When the citrus tray is full of citrus, it can be manually transferred to the packaging box. After the citrus rolls from the guide groove to the support platform, the trajectory of the citrus is generally a straight line. However, due to the blocking effect of the round holes of the citrus tray, the citrus will change its trajectory and roll out of the citrus tray. The limit frame can fix the rolling trajectory of the citrus, so that the citrus can only move along the direction of the citrus tray. When the citrus tray is full of citrus, it is removed and an empty citrus tray is placed.

[0032] In order to allow the citrus tray to be smoothly removed from the limiting frame and avoid interference with the limiting frame during movement, in a preferred embodiment, a plug plate is provided at the end of the limiting frame to control the entry and exit of the citrus tray. In this way, after the citrus tray is filled with citrus, the plug plate is lifted up to allow the citrus tray to pass through, and when the citrus is filled, the plug plate is pressed down to prevent the citrus from rolling out along the direction of the citrus tray.

[0033] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
