Description

Technical Field

[0001] The present invention relates to the technical field of fruit sorting and packaging, and specifically to a fruit cleaning and sorting device. Background Art

[0002] The harvesting, grading, packaging, and transportation of fruits and vegetables are tasks to be carried out before entering formal storage or the market. The harvesting and post-harvest commercial processing mainly have two aspects of influence on fruits. One aspect affects the quality and storability of fruits and vegetables. For example, proper harvesting time, post-harvest grading and selection, reasonable packaging, post-harvest pest and disease control, timely pre-cooling after harvest, and reasonable stacking will all have a certain impact on the storage and transportation of fruits. On the other hand, it affects the marketability of fruits and vegetables. In the field of commodity circulation, it is required that the size and specifications be consistent, the appearance be beautiful, and the packaging be delicate and appropriate to ensure the shelf life. This requires that fruits be graded and packaged according to certain standards after harvest. Some fruits need to be cleaned and waxed to improve the marketability of the fruits in order to make the appearance beautiful and extend the shelf life.

[0003] Among the common fruits on the market, such as oranges, peaches, pears, etc., with the continuous improvement of people's quality requirements for them, after the harvesting of these fruits, the sorting and packaging of them are particularly important. Taking navel oranges as an example, from being picked from the tree to the hands of customers, it has to go through multiple sub-links mainly including cleaning, disinfection, drying, etc. to ensure the high efficiency and perfection of automatic sorting and packaging. However, the existing navel orange sorting and packaging production line is not perfect and comprehensive enough, and each link is too scattered and messy, and there is almost no cooperation and integration between the links. This makes the production line equipment complex and numerous, consuming too high production costs and occupying a large amount of production space at the same time. And it is difficult to efficiently complete the sorting and packaging processing of fruits. Summary of the Invention

[0004] The technical problems to be solved by the present invention are as follows: The existing packaging and sorting links are too scattered and messy; the links such as cleaning, heat treatment, and sterilization cannot be deeply coordinated; the small fruit sorting link is too cumbersome, resulting in too high production costs and low processing efficiency.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: A fruit cleaning and sorting device, which includes a cleaning mechanism and a sorting mechanism; the sorting mechanism includes a small fruit sorting mechanism, a large fruit sorting mechanism and a defective fruit sorting mechanism, and the small fruit sorting mechanism is arranged in the cleaning chamber of the cleaning mechanism; the small fruit sorting mechanism includes a lifting table that can move up and down in the cleaning chamber, and a linear driving mechanism for driving the lifting table is arranged at the bottom of the lifting table; a fruit dropping inclined plane that slopes to one side is arranged on the upper surface of the linear driving mechanism, and a small fruit outlet is opened on the upper part of the cleaning chamber on the side close to the lower end of the fruit dropping inclined plane; a plurality of sorting columns are arranged vertically from high to low on the linear driving mechanism, and the lower sorting columns are arranged on the side far from the small fruit outlet; adjacent sorting columns are evenly spaced, and the spacing size is the radial size of the small fruit sorting standard; an outlet is opened on the upper part of the cleaning chamber on the side close to the lower sorting column; the outlet is connected to a sterilization mechanism, and the sterilization mechanism is connected to a heat treatment mechanism; the small fruit outlet is communicated with a defective fruit storage bin through a small fruit channel.

[0006] The beneficial effects of the present invention are as follows: The multiple fruit sorting and packaging links are organically combined, and the initial sorting of the fruit size is completed through the fruit dropping inclined plane and sorting columns arranged in an orderly manner from high to low during the efficient cleaning process; then, the secondary sorting, high-efficiency sterilization, and drying and heat preservation operations of the fruit are continuously and compactly completed by using the orderly connected sterilization mechanism and heat treatment mechanism, so as to complete a set of closely coordinated and highly intelligent fruit sorting, packaging and processing procedures.

[0007] As a further improvement of the present invention, the technical problem to be solved is: how to uniformly control the equipment in multiple links.

[0008] To solve the above technical problems, the further improved technical solution adopted by the present invention is as follows: It also includes a control panel; the control panel is connected to and controls the cleaning mechanism, the sorting mechanism, the sterilization mechanism and the heat treatment mechanism.

[0009] The beneficial effect of the above improvement is: By setting the control panel, the operation status of the equipment can be comprehensively understood, and the equipment in each link can be controlled quickly and conveniently.

[0010] As a further improvement of the present invention, the technical problem to be solved is: how to specifically achieve the bubbling cleaning of fruits while the cleaning device is sorting.

[0011] To solve the above technical problems, the technical solution further improved by the present invention is as follows: The cleaning mechanism includes a cleaning fruit inlet provided on one side of the upper part of the cleaning chamber and a bubbling chamber provided in the lifting platform. The bubbling chamber is connected to a high-pressure blower through a blast pipe; the bubbling chamber is evenly and spacedly provided with bubbling holes for blowing out bubbles on the fruit-falling inclined plane. A cleaning liquid level line for indicating the highest position of the cleaning liquid surface is provided in the cleaning chamber slightly below the small fruit outlet; a water-changing pipe for replacing the cleaning water is provided on one side of the lower part of the cleaning chamber, and a water pump is provided on the water-changing pipe.

[0012] The beneficial effect of the above improvement is that while the sorting device drives the fruits to move up and down for sorting, bubbles are blown out from the bottom to complete the thorough cleaning of the outer surface of the fruits.

[0013] As a further improvement of the present invention, the technical problem to be solved is that the up and down movement of the lifting platform will cause the liquid level of the cleaning water to change, thereby affecting the water inlet at the fruit outlet or incomplete cleaning.

[0014] To solve the above technical problems, the technical solution further improved by the present invention is as follows: A cleaning observation window is provided on the outside of one side of the cleaning chamber; the linear drive mechanism is a cylinder part; the sorting column is hollow inside and is connected to the bubbling chamber, and bubbling side holes for blowing out bubbles are provided on the side wall of the sorting column; a limiting plate is provided on the side of the fruit outlet close to the lifting platform, and a limiting protrusion cooperating with it is provided on the lifting platform directly below the limiting plate.

[0015] The beneficial effect of the above improvement is that a cleaning liquid level line is set to ensure that the liquid level is always lower than the fruit outlet; at the same time, in order to avoid the clogging of the bubbling holes by dirt particles during the cleaning process, the sorting column is made hollow and bubbling side holes are provided on the side; also, by setting the limiting protrusion and the limiting plate, the lifting platform is prevented from rising too high, thus affecting the normal progress of the sorting process.

[0016] As a further improvement of the present invention, the technical problem to be solved is how the sterilization mechanism specifically realizes the comprehensive sterilization operation of fruits.

[0017] To solve the above technical problems, the technical solution further improved by the present invention is as follows: The sterilization mechanism includes a sterilization chamber. A sterilization fruit inlet is provided on one side of the upper part of the sterilization chamber and is communicated with the fruit outlet. A sterilization fruit outlet communicated with the heat treatment mechanism is provided at the bottom of the sterilization chamber; a plurality of atomizing nozzles spraying downward are provided at the top of the sterilization chamber. The atomizing nozzles are connected to a sterilization liquid storage tank through a liquid flow pump outside the sterilization chamber; a plurality of fruit-falling inclined plates are evenly and spacedly arranged in a "zigzag" shape from top to bottom directly below the atomizing nozzles in the sterilization chamber. The bottom end of the higher fruit-falling inclined plate faces the upper surface of the lower fruit-falling inclined plate; buffer belts for buffer protection are evenly and spacedly arranged horizontally on the fruit-falling inclined plates.

[0018] The beneficial effects of the above improvements are as follows: The fruits roll down from the upper part of the sterilization chamber, and after passing through the sterilizing liquid sprayed by the atomizing nozzles, they keep tumbling during the continuous falling process, ensuring that the surface is completely in contact with the sterilizing liquid.

[0019] As a further improvement of the present invention, the technical problem to be solved is: Fruits with too large a size also need to be sorted to ensure that the fruits are of the same size and the quality is more standardized.

[0020] To solve the above technical problem, the technical solution adopted in the further improvement of the present invention is: The sorting mechanism is provided with a large fruit sorting mechanism at the fruit outlet of the sterilization chamber. The large fruit sorting mechanism includes a large fruit sorting opening arranged on the fruit outlet of the sterilization chamber; a large fruit channel is arranged at the bottom of the sterilization chamber below the large fruit sorting opening, and the large fruit channel is communicated with a large fruit storage bin; the opening size at the large fruit sorting opening is the radial size of the large fruit sorting standard.

[0021] The beneficial effects of the above improvements are as follows: A large fruit sorting opening with an opening size of the radial size of the large fruit sorting standard is provided, so that the fruits that originally passed through the fruit outlet of the sterilization chamber are screened again by size; the over-sized fruits will be intercepted and fall down into the large fruit channel, and finally sent to the large fruit storage bin for standby.

[0022] As a further improvement of the present invention, the technical problem to be solved is: How the heat treatment structure dries and thermally preserves the fruits that have completed cleaning and sterilization.

[0023] To solve the above technical problem, the technical solution adopted in the further improvement of the present invention is: The heat treatment mechanism includes a vertically arranged fruit delivery channel. One side of the lower part of the fruit delivery channel is provided with a heat treatment fruit inlet, and the heat treatment fruit inlet is communicated with the sterilization mechanism through a fruit passing channel; a hot air outlet is arranged at the bottom of the fruit delivery channel, the hot air outlet is communicated with a hot air blower, and a partition net plate for partition protection is arranged at the hot air outlet; the top of the fruit delivery channel is communicated with a good product storage box arranged above the cleaning chamber.

[0024] The beneficial effects of the above improvements are as follows: Through the fruit delivery channel that is just slightly larger than the standard fruit size, hot air is introduced to blow the fruits to move upward in the channel, and the fruits are dried during this process; at the same time, the good product storage box can provide a thermal preservation environment for the fruits after drying.

[0025] As a further improvement of the present invention, the technical problem to be solved is: In addition to the shape and size of the fruits, dried fruits with too low internal moisture also do not meet the good fruit standard and need to be sorted and removed.

[0026] To solve the above technical problems, the technical solution further improved by the present invention is as follows: A sub-quality fruit sorting mechanism is provided between the fruit feeding channel and the good-quality product storage box; the sub-quality fruit sorting mechanism includes a speedometer disposed on the inner wall of the middle part of the fruit feeding channel, and the speedometer is connected and controls a linear motor disposed on one side of the upper part of the fruit feeding channel through a connecting wire; a sub-quality fruit sorting opening is formed in the fruit feeding channel at the position of the linear motor, and a guiding turning plate that can be turned over into the fruit feeding channel is disposed in the sub-quality fruit sorting opening; the bottom of the guiding turning plate is movably connected to the fruit feeding channel through a hinge seat, and the back of the guiding turning plate is movably hinged to the front end of the linear motor through a rotating push rod; a good-quality fruit channel is communicated and disposed on the upper part of the fruit feeding channel slightly lower than and away from the sub-quality fruit sorting opening, and a dried fruit channel is communicated and disposed at the top of the fruit feeding channel; the good-quality fruit channel leads to the good-quality product storage box, and the dried fruit channel leads to the sub-quality fruit storage bin.

[0027] The beneficial effect of the above improvement is that a sub-quality fruit sorting mechanism is provided in the fruit feeding channel. For fruits with similar sizes, if the internal moisture is too low, the quality of such dried fruits will be significantly lower than that of normal good-quality fruits. By blowing hot air to make them move upward, the speed at which they pass through the channel will also be significantly different. Taking advantage of this characteristic, a speedometer is provided in the channel to measure that fruits with a speed higher than the set speed value are dried fruits with low quality, that is, insufficient internal moisture. Then, the good-quality fruits are guided to the good-quality fruit channel through the guiding turning plate, and the dried fruits are guided to the dried fruit channel, thus completing the sorting operation of sub-quality fruits.

[0028] As a further improvement of the present invention, the technical problem to be solved is that the good-quality product storage box is inconvenient to rotate and turn over.

[0029] To solve the above technical problems, the technical solution further improved by the present invention is as follows: A handle for lifting is provided on one side of the good-quality product storage box.

[0030] The beneficial effect of the above improvement is that the setting of the handle can help turn over the good-quality product storage box. Description of the Drawings
