Description

Technical Field

[0001] This invention relates to the field of camellia fruit processing equipment, specifically a camellia fruit peeling machine. Background Technology

[0002] After the fresh camellia fruit is harvested, the seeds and shells need to be separated. In the past, the sun-drying method was mostly used to allow the fruit to crack naturally, and the seeds of most fruits could be separated. Those that could not be separated were peeled manually. However, due to the long time involved and the susceptibility to weather conditions, the peeling efficiency of fresh camellia fruit was low due to factors such as weather, site conditions, and manual labor efficiency. In view of this, we propose a peeling machine for fresh camellia fruit. Summary of the Invention

While the shelling separation mechanism initially separates the fresh camellia seeds, it drives the needle roller separation mechanism to further separate the mixture of shelled camellia seeds and shells.

[0006] The shell-breaking and anti-blocking mechanism is installed on the shell-peeling and separating mechanism. The needle roller separation mechanism further separates the mixture of shelled camellia seeds and shells while driving the shell-breaking and anti-blocking mechanism to crush the shells separated by the shell-peeling and separating mechanism and prevent the shell falling area on the shell-peeling and separating mechanism from becoming blocked.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 8 The present invention provides a technical solution: a shelling machine for fresh camellia fruit, including a shelling and separation mechanism, which is used to shell fresh camellia fruit and perform preliminary separation of camellia seeds and shells;

[0029] The needle roller separation mechanism is installed on the shelling separation mechanism. While the shelling separation mechanism initially separates the fresh camellia seeds, it drives the needle roller separation mechanism to further separate the mixture of shelled camellia seeds and shells.

[0030] The shell-breaking and anti-blocking mechanism is installed on the shell-peeling and separating mechanism. The needle roller separation mechanism further separates the mixture of shelled camellia seeds and shells while driving the shell-breaking and anti-blocking mechanism to crush the shells separated by the shell-peeling and separating mechanism and prevent the shell falling area on the shell-peeling and separating mechanism from becoming blocked.

[0031] In this embodiment, the shelling and separating mechanism includes an outer sleeve 1, which has openings at both ends and a support leg 7 fixed at the bottom. A shaft bracket 3 is fixed to the upper side of the inner wall of the outer sleeve 1 near both openings. Two spiral shafts 2 are rotatably connected to the shaft bracket 3. The two spiral shafts 2 are arranged parallel to each other and are connected by a pulley assembly 5. The transmission belt in the pulley assembly 5 is arranged in an "∞" shape. One of the spiral shafts 2 is connected to a motor, which is fixed to the outer sleeve 1. The motor is not shown in this application. The cross-section of the outer sleeve 1 consists of two oppositely arranged semi-circular arc segments and two straight segments connected end to end. The arc openings of the two semi-circular arc segments are opposite each other, and the two straight segments are arranged parallel to each other. The centers of the two semi-circular arc segments are located on the center lines of the two spiral shafts 2. The feed end of the spiral shaft 2 is thinner, and the discharge end is thicker, forming a cone shape. The conical surface of the spiral shaft 2 has knurled patterns, which are not shown in the schematic diagram. To increase friction and give the camellia fruit a certain torque on the blades, making it easier to peel, the inner bottom surface of the outer sleeve 1 is provided with a circular hole array 16, a blade array 17, and an irregular hole array 18. The circular hole array 16, blade array 17, and irregular hole array 18 are arranged sequentially from the feed end to the discharge end of the spiral shaft 2. The circular hole array 16 includes multiple circular through holes arranged in an array at the bottom of the outer sleeve 1. Small-diameter fresh camellia fruit and impurities are discharged through the circular hole array 16. The blade array 17 includes blades arranged in an array and fixed at the bottom of the outer sleeve 1. Its function is to cut open the outer shell of the fresh camellia fruit. The irregular hole array 18 includes multiple irregular through holes arranged in an array at the bottom of the outer sleeve 1. The cross-section of the irregular through holes is a semi-circular structure (the arc is close to that of the camellia fruit shell), and there are outwardly protruding grooves on the arc wall. Its function is to separate and discharge a part of the shell, so as to avoid the shell accumulating too much in the outer sleeve 1.

[0032] In this embodiment, the needle roller separation mechanism includes a grid baffle 6 and a roller 25. The grid baffle 6 is fixed at the upper end of the opening of the outer sleeve 1 corresponding to the discharge end of the spiral shaft 2. A discharge plate 33 is fixed at the lower end of the opening of the outer sleeve 1 corresponding to the discharge end of the spiral shaft 2. A bracket 4 is fixed at the upper end of the opening. A second shaft bracket 23 is fixed on the bracket 4. The lower end of the second shaft bracket 23 is rotatably connected to the roller 25. The roller 25 is located between the grid baffle 6 and the discharge plate 33. The roller 25 is perpendicular to the spiral shaft 2. A shaft rod 19 is fixed on the bracket 4. Two guide wheels 21 are sleeved on the shaft rod 19 and rotatably connected to it. The two guide wheels 21 are arranged vertically. One of the discharge ends of the spiral shaft 2 is coaxially fixedly connected to a grooved wheel 20. One end of the roller 25 is coaxially fixedly connected to a grooved wheel 26. The grooved wheel 20 and the grooved wheel 26 are connected by a belt 22. The two flat sections of the belt 22 are respectively wound around the two guide wheels 21.

[0033] In this embodiment, a plurality of needle rods 29 are radially arranged on the periphery of the roller shaft 25. One end of the needle rod 29 pointing towards the roller shaft 25 is fixed to the outer side wall of the roller shaft 25 by a spring 28. The spring 28 gives the needle rod 29 a certain degree of toughness to avoid damaging the camellia seeds. The other end of the needle rod 29 is fixed with a hard needle tip 30. The needle rod 29 can pass through the grid groove on the grid baffle 6.

[0034] In this embodiment, the shell breakage prevention mechanism includes multiple fixed clamping plates 13 fixed to the bottom surface of the outer sleeve 1. The multiple fixed clamping plates 13 are located at the bottom of the irregular hole array 18. The multiple fixed clamping plates 13 are arranged parallel to each other and at equal intervals. A movable clamping plate 14 is provided between two adjacent fixed clamping plates 13. The movable clamping plate 14 is arranged parallel to the fixed clamping plates 13. An air passage 32 is opened in the movable clamping plate 14. A sliding rod 15 is vertical and passes through each fixed clamping plate 13 and is slidably connected to each fixed clamping plate 13. The sliding rod 15 is vertical and passes through each movable clamping plate 14 and is fixedly connected to each movable clamping plate 14. One end of the sliding rod 15 is fixedly connected to a push-pull rod 31, and a strip-shaped through hole 27 is opened on the push-pull rod 31. A pin 24 is slidably connected in the strip-shaped through hole 27. The pin 24 is rotatably connected to a position away from the center on the surface of the grooved wheel 26.

[0035] In this embodiment, a pump cylinder 11 is fixed to the bottom surface of the outer sleeve 1. A piston plate 12 is slidably connected inside the pump cylinder 11. The end of the slide rod 15 away from the push-pull rod 31 is perpendicular to and fixedly connected to the piston plate 12. One-way valve 8 and one-way valve 10 are fixed and connected to the end wall of the pump cylinder 11. One-way valve 10 is connected to the lower end of each air passage 32 through the air pipe 9. The conduction direction of one-way valve 8 points to the inside of the pump cylinder 11, and the conduction direction of one-way valve 10 points to the inside of the air pipe 9.

[0036] Working principle and advantages of this invention: The working process of this camellia oil fruit peeling machine is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the motor is started, causing it to drive the spiral shaft 2 connected to it to rotate. This causes the two spiral shafts 2 to rotate in opposite directions under the transmission of the pulley assembly 5. Fresh camellia fruit is fed into the outer sleeve 1 through the inlet end of the outer sleeve 1 (i.e., the inlet end of the spiral shaft 2). Under the rotation of the two spiral shafts 2, the fruit moves towards the outlet end of the outer sleeve 1, and is simultaneously kneaded by the two spiral shafts 2. This causes the fresh camellia fruit to rotate as it moves. When the fresh camellia fruit passes through the area where the circular hole array 16 is located, it is clamped... Smaller particles of fresh camellia fruit and impurities are separated and discharged through the circular holes. When the fresh camellia fruit passes through the area where the blade array 17 is located, the blades cut open the shell of the fresh camellia fruit. Then, under the kneading action of the two spiral shafts 2, the camellia seeds and shells are separated. When the camellia seeds and shells pass through the area where the irregular hole array 18 is located, some of the shells are discharged and separated through the irregular holes. On the one hand, this avoids the shells from accumulating and blocking in the outer sleeve 1. On the other hand, discharging some of the shells reduces the workload of subsequent separation of camellia seeds and shells, thus achieving the separation of fresh camellia fruit.

[0038] As described above, the outer sleeve 1 discharges camellia seeds and another part of the outer shell onto the discharge plate 33. While the spiral shaft 2 rotates, it simultaneously drives the grooved wheel 20 to rotate, which in turn drives the grooved wheel 26 to rotate via the belt 22. This causes the grooved wheel 26 to rotate synchronously with the roller shaft 25, which in turn drives the needle rods 29 on it to rotate. During this process, the hard needle 30 penetrates the outer shell, and as the roller shaft 25 rotates, the needle rods 29 drive the outer shell through the grid groove of the grid baffle 6. Under the action of the grid groove, the outer shell is separated from the hard needle 30, thereby separating the other part of the outer shell from the camellia seeds and achieving further separation of the camellia seeds and the outer shell.

[0039] As the grooved wheel 26 rotates, it drives the slide bar 15 to move back and forth via the pin 24 and push-pull rod 31. This causes the slide bar 15 to simultaneously drive each movable clamping plate 14 to move back and forth between the corresponding two fixed clamping plates 13. This causes the movable clamping plates 14 and the fixed clamping plates 13 to be crushed from the outer shell stuck in the irregular hole for collection. At the same time, the slide bar 15 drives the piston plate 12 to slide back and forth inside the pump barrel 11. This causes the piston plate 12 to alternately apply suction and compression forces to the pump barrel 11. When the piston plate 12 applies suction force to the pump barrel... At that time, since the conduction direction of one-way valve 8 is pointing towards the inside of pump cylinder 11 and the conduction direction of one-way valve 10 is pointing towards the inside of air pipe 9, the suction force draws external air into pump cylinder 11. When piston plate 12 applies compression force to the inside of pump cylinder, the compression force transports the air in pump cylinder 11 through air pipe 9 to air passages 32 in each moving clamp plate 14, and then blows it out through the upper port of air passage 32 to the lower end of the irregular hole. The backflow of airflow causes the outer shell stuck in the irregular hole to be discharged, thereby achieving real-time unblocking of the irregular hole and avoiding blockage.
