Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.

Referring to fig. 1 to 6, the separation and extraction device for processing fruits and vegetables according to the present invention has different extraction positions for fruits and vegetables according to the difference of the fruits and vegetables to be processed; for example, the purpose of processing pomegranate is to extract pomegranate seeds, and the rest parts (such as pomegranate peel and internal diaphragm) are not needed, so the separating and extracting device for processing fruits and vegetables of the present invention needs to separate pomegranate seeds when processing pomegranate. When the pomelo and the orange are processed, the pulp parts of the pomelo and the orange are needed, and the rest parts are similar to the pericarp and the fruit seed, so the pericarp and the fruit seed in the pomelo and the orange need to be separated when the pomelo and the orange are processed by the separation and extraction device for processing the fruits and the vegetables.

Therefore, the separating and extracting device for processing fruits and vegetables comprises a frame 1, a cover body 2 arranged on the frame 1 and a separating mechanism positioned in the cover body 2, wherein the separating mechanism comprises a sieve barrel 5, a first tooth comb 11, a second tooth comb 10 and a rotary driving mechanism for driving the first tooth comb 11 and the second tooth comb 10 to synchronously and reversely rotate, and sieve holes (not drawn in the attached drawings of the specification) are arranged on the sieve barrel 5; the first tooth comb 11 and the second tooth comb 10 are positioned in the sieve barrel 5, and the first tooth comb 11 is positioned inside the second tooth comb 10; wherein, the comb teeth of the first comb teeth 11 and the second comb teeth 10 are round bars.

Because the flesh undamaged peel/seed/meat/diaphragm separator among the prior art need smash the fruit vegetables through strip tooth comb and slice tooth comb when separating the fruit vegetables, but because the slice broach comprises the slab of multiunit straight line arrangement, the area of contact of every plate and fruit vegetables is little, consequently easily causes the damage to the flesh/fruit grain of fruit vegetables (for example, the pomegranate seed of pomegranate) because of shearing the destruction when smashing fruit vegetables to influence processingquality. Therefore, in the utility model, the comb teeth of the second comb 10 are set to be round bars as same as the first comb 11, so as to increase the contact area with fruits and vegetables (such as pomegranate), and reduce the shearing force applied to pomegranate seeds in the pomegranate, thereby ensuring that the pomegranate seeds in the pomegranate are not damaged during grain stripping.

As a further preferred scheme, the tail end of the round rod is of a round head structure, so that sharp corners cannot appear at the tail end of the round rod, cutting damage to materials is avoided, and nondestructive processing of fruits and vegetables is guaranteed.

Referring to fig. 1 to 6, a plurality of baffles 12 are arranged in the screen barrel 5, and the plurality of baffles 12 are arranged along the axial direction of the screen barrel 5 and are distributed along the circumferential direction of the screen barrel 5. The purpose is as follows: according to the separation and extraction device, the plurality of baffles 12 are arranged in the sieve barrel 5, and the plurality of baffles 12 are arranged along the axial direction of the sieve barrel 5 and are simultaneously distributed along the circumferential direction of the sieve barrel 5; therefore, in the process of separating all the parts of the fruits and vegetables, the baffle 12 can limit the movement of the fruits and vegetables, and the fruits and vegetables can move forwards beyond the baffle 12 only when the fruits and vegetables move to the area which is not blocked by the baffle 12 under the stirring of the first tooth comb 11 and the second tooth comb 10, so that the movement time of the fruits and vegetables in the sieve barrel 5 can be prolonged on the premise of not increasing the volume of equipment, the stripping rate is improved, the fruits and vegetables are separated more thoroughly, the separation efficiency is improved, and the cost of raw materials in fruit and vegetable processing is reduced.

Referring to fig. 1-6, the sum of the central angles of the plurality of baffles 12 in the circumferential direction is greater than or equal to 360 °, so that the material to be separated is blocked by at least one baffle 12 during the movement along the axial direction of the screen barrel 5, and the material is prevented from being mixed. In this embodiment, the number of the baffles 12 is three, three baffles 12 are arranged along the axial direction of the sieve barrel 5, and an included angle between two adjacent baffles 12 is 120 degrees; in addition, in this embodiment, the second comb 10 is mounted on the sieve barrel 5, and the rotary driving mechanism is configured to drive the second comb 10 and the sieve barrel 5 to synchronously rotate in the same direction.

Referring to fig. 1-6, the first comb teeth 11 are rotatably connected to the frame 1 through a first rotating shaft 6; the second tooth comb 10 is rotationally connected to the rack 1 through a second rotating shaft 7; the first rotating shaft 6 and the second rotating shaft 7 are coaxially arranged in a nested manner, wherein the second rotating shaft 7 is positioned outside the first rotating shaft 6; a rotating bearing is arranged between the first rotating shaft 6 and the second rotating shaft 7; the inner side and the outer side of the rotating bearing are respectively connected with the first rotating shaft 6 and the second rotating shaft 7; the rotary driving mechanism comprises a rotary motor, the rotary motor is arranged on the rack 1 and is connected with the second rotating shaft 7 through a gear transmission mechanism 9, and the rotary motor is connected with the first rotating shaft 6 through a synchronous belt transmission mechanism 8 or a chain transmission mechanism.

When the sieve drum is in operation, the rotating motor (not shown in the attached drawings of the specification) drives the second rotating shaft 7 to rotate through the gear transmission mechanism 9, so as to drive the second rotating shaft 7, and the second tooth comb 10 and the sieve drum 5 which are arranged on the second rotating shaft 7 to rotate; meanwhile, the rotating motor drives the first rotating shaft 6 and a second tooth comb 10 arranged on the first rotating shaft 6 to rotate reversely through a synchronous belt transmission mechanism 8, and the rotating direction is opposite to that of the second tooth comb 10; therefore, the first tooth comb 11 and the second tooth comb 10 can be driven to synchronously rotate through the respective transmission characteristics of the gear transmission mechanism 9 and the synchronous belt transmission mechanism 8 through a group of rotating motors, and the rotating directions are opposite, so that the purpose of saving the manufacturing cost is achieved.

In addition to the above structure, the rest of the first comb teeth 11 and the second comb teeth 10 can be implemented by referring to the specific structure of the strip comb teeth and the sheet comb teeth in the 'fruit flesh non-damage peel/seed/meat/membrane separator and the separation method thereof' disclosed in the utility model patent application with application publication No. CN 106723149A, and similarly, the comb teeth in the first comb teeth 11 are also arranged spirally, which is beneficial to forward conveying of fruits and vegetables during peeling.

Referring to fig. 1-6, the sieve barrel 5 is obliquely arranged on the frame 1, which is beneficial to further promote the pomegranate in the sieve barrel 5 to move forwards; meanwhile, the inclination angle of the sieve barrel 5 can be adjusted by an angle adjusting mechanism; the angle adjusting mechanism can adopt a traditional jack adjusting mode, namely, one side of the sieve barrel 5 is rotatably connected to the rack 1, so that the sieve barrel 5 can rotate or swing around a rotating point; and the other side of sieve bucket 5 is connected with the jack, drives the opposite side motion of sieve bucket 5 through the jack to drive sieve bucket 5 around its rotation end swing, with this realization to sieve bucket 5's inclination adjust.

Besides the mode, a screw rod adjusting mode can be adopted, for example, a screw sleeve or a screw hole matched with the screw rod is arranged on the sieve barrel 5, and the other side of the sieve barrel 5 is driven to swing around the rotating end of the sieve barrel 5 by driving the screw rod to rotate (the principle of the screw rod driving mechanism is similar to that of a screw rod driving mechanism), so that the inclination angle of the sieve barrel 5 can be adjusted; in addition, this adjustment may also utilize a self-locking function between the screw and the threaded sleeve/hole, which still locks the sieve barrel 5 in this tilted state when the drive mechanism (e.g. motor) is not in operation.

In addition, sieve bucket 5 is made through stamping forming's mode, can avoid causing the damage to pulp/fruit seed like this, because traditional sieve bucket 5 is made with laser cutting's mode, the burr appears easily like this, and these burrs cause the damage to pulp/fruit grain easily, consequently makes sieve bucket 5 through changing into stamping forming's mode, can reduce the burr in the sieve bucket 5, further reduces the breakage rate.

Referring to fig. 1 to 6, the screen holes in the screen barrel 5 are arrayed on the outer side of the screen barrel 5, and the diameters of the screen holes are sequentially reduced along the moving direction of the material. The purpose is as follows: since a great deal of pulp/seeds are peeled off at the beginning in the separation process, but the peeled pulp/seeds are less and the peels/diaphragms with small volumes are likely to fall off the later, the diameters of the sieve holes are set to be reduced in sequence along the movement direction of the fruits and vegetables, so that a great deal of pulp/seeds peeled off from the front end of the sieve barrel 5 can rapidly pass through the sieve holes to enter the pulp/seeds collection mechanism and are prevented from moving along the axial direction of the sieve barrel 5 to enter the peel/diaphragms collection mechanism; in addition, the above structure also prevents a small volume of peel/membrane falling in the end of the sieve barrel 5 from passing through the sieve holes into the pulp/seed collection mechanism.

Referring to fig. 1 to 6, the upper and lower sides of the sieve holes are rounded, so that the peeled pomegranate seeds can be prevented from being damaged, and the integrity of the peeled pomegranate seeds can be protected.

Referring to fig. 1-6, the frame 1 is provided with a feed hopper 3 at the feed inlet of the sieve barrel 5, and the feed hopper 3 is used for guiding fruits and vegetables into the sieve barrel 5; and the frame 1 is provided with a pulp/seed discharging hopper 13 below the sieve mesh for guiding the peeled pulp/seed into a pulp/seed collecting mechanism (such as a collecting box) uniformly; in addition, the frame 1 is provided with a peel/diaphragm discharge hopper 4 at the tail end of the sieve barrel 5 for collecting bulky peel/diaphragm.

Referring to fig. 1-6, the working principle of the separation and extraction device for fruit and vegetable processing of the present invention is as follows:

when the fruit and vegetable harvesting machine works, fruits and vegetables to be processed are conveyed into the sieve barrel 5, then the rotary driving mechanism drives the first tooth comb 11 and the second tooth comb 10 to synchronously and reversely rotate, and because the first tooth comb 11 and the second tooth comb 10 are provided with the mutually staggered comb teeth, the first tooth comb 11 and the second tooth comb 10 smash the peel of the fruits and vegetables in the rotating process of the first tooth comb 11 and the second tooth comb 10, so that the pulp/seeds in the fruits and vegetables fall onto the sieve barrel 5 and enter the pulp/seed collecting mechanism through the sieve holes in the sieve barrel 5; in the process, the fruits and vegetables also move along the axial direction of the sieve barrel 5; because a plurality of baffles 12 are arranged in the screen barrel 5, the baffles 12 are arranged along the axial direction of the screen barrel 5 and are distributed along the circumferential direction of the screen barrel 5; therefore, the fruits and vegetables are blocked by the baffle 12 in the moving process, and only when the fruits and vegetables move to the area which is not blocked by the baffle 12 under the stirring of the first comb 11 and the second comb 10, the fruits and vegetables can move forwards continuously over the baffle 12, so that the moving time of the fruits and vegetables in the sieving barrel 5 can be prolonged, and all parts of the fruits and vegetables are separated more thoroughly; when the fruit and vegetable pulp/seeds are completely separated, the rest of the peel/diaphragm moves to the outlet at the tail end of the sieve barrel 5 and is collected by a peel/diaphragm collecting mechanism.

The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
