Description

Technical Field

[0001] The utility model relates to a peeling device, in particular to a torreya grandis green fruit peeling machine. Background Art

[0002] For the peeling of torreya grandis green fruits, the currently adopted solution in the market is friction peeling. The peeling is carried out by the cooperation of a fixed inner cylinder and a rotating outer cylinder. At the same time, the outer cylinder surface is provided with openings. The green fruits are put into the sandwich layer between the outer cylinder and the inner cylinder. When the outer cylinder rotates, the pericarp is rubbed off by the friction between the inner wall of the outer cylinder, the outer wall of the inner cylinder and the green fruits. When the pericarp is rubbed off, the internal seeds leak out through the openings of the outer cylinder.

[0003] Since the pericarp of the green fruit contains oily juice, the oily juice is squeezed out during the friction process. As the production time prolongs, more and more pericarp will be stuck to the cylinder wall due to the viscosity of the oily juice, so that the internal seeds cannot immediately leak out through the openings of the outer cylinder after the torreya grandis green fruits are peeled. During the friction, the outer shell of the seeds will be damaged. Once the outer shell of the seeds is damaged, the torreya grandis kernels inside the seeds will quickly oxidize and deteriorate, losing their edible characteristics. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a torreya grandis green fruit peeling machine that will not damage the outer shell of torreya grandis seeds and protect the edibility of torreya grandis kernels.

[0005] The technical solution of the utility model is as follows:

[0006] A torreya grandis green fruit peeling machine includes a frame. An inclined chain transmission mechanism is installed on the frame. Fruit support blocks are evenly arranged on the chain of the chain transmission mechanism. Grooves are provided on the fruit support blocks for falling and upward conveying of torreya grandis green fruits.

[0007] A feeding hopper is arranged at the lower part of the chain transmission mechanism on the frame. The chain transmission mechanism passes through the feeding port at the lower end inside the feeding hopper for feeding torreya grandis green fruits to be peeled.

[0008] Two brackets are symmetrically arranged on both sides of the upper part of the chain transmission mechanism on the frame. A plurality of rotatable pressure rollers are evenly arranged between the two brackets. The pressure rollers are inclined and arranged above the fruit support blocks of the chain transmission mechanism.

[0009] Support sprockets are respectively arranged on the frame corresponding to the lower part of each pressure roller. The support sprockets are inserted into the inside of the chain transmission mechanism and meshed with the chain of the chain transmission mechanism for supporting the chain and cooperating with the pressure rollers to squeeze the green fruits.

[0010] As a further preference, a rectangular discharge port is arranged at the front end of the feeding port of the feeding hopper. When the torreya grandis green fruits fall into the grooves in parallel, they can follow the chain transmission mechanism through the discharge port; otherwise, the torreya grandis green fruits will be blocked back into the feeding hopper by the discharge port.

[0011] As a further preference, the outer layer of the pressing roller is made of a flexible material.

[0012] As a further preference, there are three pressing rollers, and the inclination directions of the two upper pressing rollers are opposite to that of the lowermost pressing roller.

[0013] As a further preference, both ends of the central axis of the pressing roller are respectively fixed to a bracket by nuts, and are fixed to two supports through the bracket.

[0014] As a further preference, the fruit support block is connected between two adjacent links of the chain through two L-shaped brackets.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By cooperating the uniformly distributed multiple inclined pressing rollers with the fruit support blocks on the chain transmission mechanism, the mechanized peeling of torreya grandis green fruits can be realized, imitating the process of manually squeezing the green peel to remove the seeds. During the peeling process, the integrity of the fruit peel can be ensured, the oily juice in the fruit peel will not be squeezed out, avoiding the stickiness of the fruit peel. At the same time, the outer shell of the seeds will not be damaged, protecting the edibility of torreya grandis kernels;

[0017] 2. Mechanized continuous production can be achieved, and only one person is required for feeding, which can reduce labor costs and improve production efficiency, bringing higher product profits to production enterprises. Description of the Drawings

Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-6 shown, a torreya grandis green fruit peeling machine involved in the present utility model includes a trapezoidal frame 1. An inclined chain transmission mechanism 4 is installed on the frame 1. The two ends of the driving shaft 401 and the driven shaft 402 of the chain transmission mechanism 4 are respectively installed on the inclined beams on the top surface of the frame 1 through bearing seats and bearings, and the driving shaft 401 is located above the inclined beam. A motor bracket 11 is fixed on one side of the frame 1, and a driving motor 10 is installed on the motor bracket 11. The output end of the driving motor 10 is coaxially connected to the driving shaft 401.

[0027] Fruit support blocks 3 are evenly distributed on the chain of the chain transmission mechanism 4. The bottom surface of each fruit support block 3 is symmetrically fixed with two L-shaped brackets 2 by screws and is connected between two adjacent pin shafts of the chain through the two L-shaped brackets 2. A semi-circular groove is provided on the fruit support block 3 along the axial direction of the pin shaft for falling and upwardly conveying the torreya grandis green fruits to be peeled.

[0028] A feeding hopper 5 is fixed on the frame 1 below the chain transmission mechanism 4 by bolts. The chain of the chain transmission mechanism 4 passes through the lower material outlet 501 at the lower end inside the feeding hopper 5 for feeding the torreya grandis green fruits to be peeled. The inner cavity of the feeding hopper 5 is conical, and the width of the lower material outlet is slightly smaller than the length of the fruit support block 3, so that the torreya grandis green fruits can fall into the groove of the fruit support block 3. A rectangular discharge port 502 is provided at the front end of the lower material outlet 501 of the feeding hopper 5. When the torreya grandis green fruits fall into the groove in parallel, they can pass through the discharge port along with the chain transmission mechanism 4; otherwise, the torreya grandis green fruits will be blocked back into the feeding hopper 5 by the discharge port 502.

[0029] Two channel-shaped brackets 7 are symmetrically fixed on both sides above the chain transmission mechanism 4 on the frame 1. A plurality of rotatable pressing rollers 9 are evenly distributed between the two brackets 7. The pressing rollers 9 are axially inclined above the fruit support blocks 3 of the chain transmission mechanism 4, so that the gap between the outer edge of the pressing roller 9 and both ends of the fruit support block 3 is not equal; the pressing roller 9 is composed of a central shaft and a sleeve installed outside the central shaft through bearings. The two ends of the central shaft of each pressing roller 9 are respectively fixed on a channel-shaped bracket 8 by nuts and are fixed on the two brackets 7 through the bracket 8 and bolts.

[0030] The outer surface layer of the sleeve of the pressure roller 9 is made of flexible materials such as rubber. In this embodiment, three pressure rollers are taken as an example, and the inclination directions of the two upper pressure rollers 9 and the one lower pressure roller 9 are opposite. There are blanking gaps 13 respectively between the fruit support blocks 3 on the chain transmission mechanism 4 and the brackets 7 on both sides for discharging the shelled torreya grandis seeds.

[0031] Corresponding to each pressure roller 9 below, a rotatable support sprocket 6 is installed on the frame 1 through a wheel axle. Both ends of the wheel axle are installed on the frame 1 through bearing seats and bearings. The support sprocket 6 is inserted into the interior of the chain transmission mechanism 4 and meshes with the chain of the chain transmission mechanism 4 to support the fruit support blocks 3 on the chain to cooperate with the pressure roller 9 to squeeze the green fruits.

[0032] Receiving troughs 12 are respectively placed below the bottom of the frame 1 under the multiple pressure rollers 9 and the upper end of the chain transmission mechanism 4 for receiving the shelled torreya grandis green fruit peels and seeds.

[0033] During use, the steps are as follows:

[0034] 1. Start the drive motor 10 to drive the chain transmission mechanism 4 to run at a low speed; put the torreya grandis green fruits to be shelled into the feeding hopper 5, and the torreya grandis green fruits falling into the feeding hopper 5 fall on the fruit support blocks 3 through the feeding port; when the torreya grandis green fruits fall parallel into the grooves, they can pass through the discharge port following the chain transmission mechanism 4; otherwise, the torreya grandis green fruits will be blocked back into the feeding hopper 5 by the discharge port.

[0035] 2. When the torreya grandis green fruits that fall parallel into the grooves follow the chain transmission mechanism 4 into the area below the pressure roller 9, the green fruits are squeezed through the cooperation of the inclined pressure roller 9 and the fruit support block 3; since the outer surface layer of the pressure roller 9 is a flexible material, the green fruits can be effectively wrapped; at the same time, the pressure at the lower end of the pressure roller 9 on the green fruits is large, and the pressure at the upper end is small, imitating manual squeezing of the green fruits to extract the seeds under the dual action of wrapping and pressure.

[0036] 3. When the seeds are extruded and the peels are intact, due to the flexibility of the outer surface layer of the pressure roller 9, the oily juice in the peels will not be extruded, and at the same time, even if the seeds come into contact with the pressure roller 9 after being extruded, the outer shells of the seeds will not be damaged. The extruded seeds fall into the corresponding receiving trough 12 below through the blanking gaps 13 on both sides of the fruit support block 3; when the squeezed peels follow the fruit support block 3 to the upper end of the chain transmission mechanism 4, they naturally fall into the corresponding receiving trough 12 below with the flipping and will not stick to the fruit support block 3.

[0037] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples herein.
