Description

Technical Field

[0001] The utility model belongs to the technical field of oil-tea camellia seed processing equipment, and particularly relates to an oil-tea fruit shell and seed separation device. Background Technique

[0002] As a woody oil crop with rich nutritional value and wide uses, oil-tea camellia has a long planting history in China. The oil-tea seeds have a high oil content, and the extracted camellia oil not only has rich nutritional value but also has a unique flavor, which is deeply loved by consumers. However, in the processing of oil-tea fruits, especially in the separation link of oil-tea fruit shells and seeds, it has always been a technical bottleneck restricting the development of the oil-tea industry.

[0003] At present, the main methods for separating oil-tea fruit shells and seeds on the market are as follows:

[0004] Manual separation: The oil-tea fruit shells and seeds are separated by manual means such as knocking and rubbing. Although this method is simple, its efficiency is extremely low, and the labor intensity is high, which is not conducive to large-scale production.

[0005] Friction separation: A friction separation machine is used to separate the oil-tea fruit shells and seeds through the action of friction. Although this method is more efficient than manual separation, it is easy to cause damage to the oil-tea seeds and affect the quality of camellia oil.

[0006] Vibration screening: Vibration screening equipment is used to separate the oil-tea fruit shells and seeds. This method reduces the damage to the seeds to a certain extent, but the separation effect is greatly affected by the maturity of the oil-tea fruits and the hardness of the shells, and the separation efficiency is unstable.

[0007] Air separation: The oil-tea fruit shells and seeds are separated by wind force. This method requires a high degree of dryness of the oil-tea fruits, and a large amount of dust is generated during the separation process, causing environmental pollution.

[0008] The above methods all have certain limitations in terms of separation efficiency, degree of seed damage, operation convenience, etc. To solve these problems, improve the separation efficiency and quality of oil-tea fruit shells and seeds, and reduce production costs, the utility model provides an oil-tea fruit shell and seed separation device. The device aims to achieve an efficient and low-damage separation effect through innovative design, and is suitable for the large-scale production needs of oil-tea processing enterprises.

Specific embodiments

[0027] The following further describes the present application in detail. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Embodiment 1

[0029] As Figures 1-4 shown, an oil-tea fruit shell and seed separation device includes a support frame, and the support frame includes two bases. The base includes a bottom plate 11, and the bottom plate 11 can be fixed to the ground or a support surface by anchor bolts. A connecting block 12 is fixed at one end of the bottom plate 11, and a sleeve 13 is rotatably installed at the other end of the bottom plate 11. The sleeve 13 has internal threads. A bolt 14 is threadedly connected to the sleeve 13.

[0030] Two bottom plates 11 are respectively connected to a fixed frame 10 through a connecting block 12 and a bolt 14. Specifically, the fixed frame 10 is rotatably connected to both the connecting block 12 and the bolt 14. Since there is an angle between the bolt 14 and the bottom plate 11, the fixed frame 10 has an inclination. The inclination of the fixed frame 10 can be indirectly controlled by rotating the bolt 14 to control the distance that the bolt 14 enters the sleeve 13.

[0031] A plurality of roller shafts 2 parallel to each other are rotatably installed on the fixed frame 10. A belt 3 is arranged between the plurality of roller shafts 2, and the inner surface of the belt 3 contacts the roller shafts 2.

[0032] A speed reducer 4 is fixedly arranged on the fixed frame 10. The output shaft of the speed reducer 4 is fixedly connected to one of the roller shafts 2, and a first driving motor 5 is arranged at the input end of the speed reducer 4. The first driving motor 5 operates in forward and reverse rotation, and the forward rotation time is longer than the reverse rotation time, so that the belt 3 moves forward a certain distance and then moves backward a certain distance, and the forward distance is greater than the backward distance, so that the belt 3 can maintain a forward state. Preferably, the forward distance of the belt 3 is 3 cm and the backward distance is 2 cm. As Figure 2 shown, the forward direction is the D direction and the backward direction is the R direction. The forward and backward reciprocating movement can intensify the shaking of the shell and seeds, thereby increasing the success rate of separating the shell and seeds.

[0033] The belt 3 rotates with the roller shaft 2. There is an angle between the rotation center of the roller shaft 2 and the horizontal plane, and this angle is preferably 30°. The outer surface of the belt 3 is the rotating surface 1.

[0034] A number of strip-shaped protrusions 6 parallel to each other are fixedly arranged on the outer surface, and the distance between adjacent strip-shaped protrusions 6 is preferably 15 cm. The strip-shaped protrusions 6 can form a number of adjacent grooves on the surface of the belt 3, which can guide the falling oil-tea fruit seeds, so that the oil-tea fruit seeds can be collected centrally.

[0035] A sticky member 7 is fixedly arranged between adjacent protrusions on the outer surface. The sticky member 7 is used to adhere to the oil-tea fruit shells. The sticky member 7 can be made of terry cloth, and the fibers on its surface can prevent the oil-tea fruit shells from moving.

[0036] It should be noted that by means of manual or conveyor transportation, the mixture of oil-tea fruit shells and seeds is sprinkled from above the inclined belt 3 onto the belt 3, so that the mixture falls on one end of the belt 3, as Figure 2 shown, and the mixture is put in at area a.

[0037] When the mixture falls on the belt 3, the shell part in the mixture has a greater adhesion (or frictional force, the same below) to the terry cloth, while the adhesion between the seed part in the mixture and the terry cloth is smaller. The adhesion of the terry cloth to the oil-tea fruit shells is greater than the component force of the self-gravity of the oil-tea fruit shells on the inclined plane, making it difficult for the oil-tea fruit shells to move on the terry cloth. And the component force of the self-gravity of the oil-tea fruit seeds on the inclined plane is greater than the adhesion of the terry cloth to the oil-tea fruit seeds, so the oil-tea fruit seeds slide down along the terry cloth and fall into area b.

[0038] Since the belt 3 is in a reciprocating motion state, and under the action of the adhesion force, the oil-tea fruit shells move to the end or back of the belt 3. At this time, the oil-tea fruit shells are in a suspended state, and the self-gravity of the oil-tea fruit shells is greater than the adhesion between them and the terry cloth, so the oil-tea fruit shells fall automatically and fall into area c. That is, the oil-tea fruit shells and oil-tea fruit seeds are distributed at both ends of the belt 3, realizing the precise sorting of oil-tea fruit shells and seeds.

[0039] Embodiment 2

[0040] As Figures 1-4 shown, a cleaning member for cleaning the rotating surface 1 of the rotating member is provided on the support frame. The cleaning member is a roller brush 15 rotatably mounted on the fixed frame 10. The roller brush 15 uses plastic bristles, the bristles contact the terry cloth, and the roller brush 15 is located at one end of the belt 3 close to area a.

[0041] A second driving motor 16 is fixedly installed on the fixed frame 10. The output shaft end of the second driving motor 16 is fixedly connected to the end of the roller brush 15. When the second driving motor 16 rotates, it drives the roller brush 15 to rotate. The rotation speed of the roller brush 15 is 1000 revolutions per minute, and the diameter of the roller brush 15 is preferably 16 cm. Preferably, the rotation direction of the roller brush 15 is opposite to the forward direction when the belt 3 rotates, so as to clean the sundries on the belt 3 downward.

[0042] During operation, due to the strong adhesion effect of the terry cloth, some small shells in the mixture are difficult to separate from the terry cloth under their own gravity. To improve the separation effect of the shells and seeds, a roller brush 15 is provided. When the roller brush 15 rotates and contacts the terry cloth, it can brush off the small shells on the terry cloth without affecting the normal movement of the terry cloth.

[0043] The above embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
