Description

Technical Field

[0001] This utility model relates to the field of camellia seed screening technology, and in particular to a camellia seed screening device. Background Technology

[0002] Camellia seeds are another name for oil tea seeds, which are the fruits of the oil tea tree. The oil tea tree is a major woody oil-bearing tree in my country. During the production of oil tea seeds, the outer shell needs to be removed and screened. Therefore, oil tea seed screening equipment is an essential piece of equipment in the production process.

[0003] Chinese patent announcement number CN209109608U discloses a tea seed screening device for oil extraction from tea seeds. The device includes a screening box, a feed hopper inserted through the top wall of the screening box, and a servo motor welded to the upper end of the screening box. A wind-powered screening device is installed at the upper end of the screening box. A first rotating shaft on the servo motor is connected to a first bevel gear via a coupling, and the first bevel gear meshes with a second bevel gear. The lower end of the second bevel gear is vertically connected to a rotating shaft, and the lower end of the rotating shaft reaches the inner cavity of the screening box and is rotatably connected to the upper end of the sieve plate. This invention overcomes the shortcomings of existing technologies, has a reasonable design, and a compact structure. By rotating and tilting the screening box, the screened tea seeds are effectively discharged. Simultaneously, the wind-powered screening device effectively removes floating dust and fine impurities from the tea seeds in advance. Combined with the sieve plate, cleaner tea seeds are screened for oil extraction.

[0004] However, this device has the following drawbacks in use: After the camellia seeds to be screened are poured into the inner cavity of the screening box, the air force discharged through the curved pipe blows the floating dust and fine impurities in the camellia seeds toward the dust discharge port, and they are discharged through the fine screen installed at the dust discharge port. The camellia seeds after preliminary air screening fall onto the screen plate. Then, two rotating arms drive two spreading plates to rotate, spreading the camellia seeds evenly onto the screen plate. The camellia seeds fall through the sieve holes on the screen plate to the bottom of the screening box, while large particles of impurities and branches remain at the top of the screen plate. However, when using air force to initially filter impurities, this device has difficulty removing impurities of the same size as the camellia seeds. Therefore, when spreading the camellia seeds on the screen plate, camellia seeds and impurities of the same size as the camellia seeds will pass through the sieve holes and fall to the bottom of the screening box, resulting in incomplete screening. To address the above drawbacks, we propose a camellia seed screening device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a camellia seed screening device.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a camellia seed screening device, comprising:

[0012] Preferably, the left end of the guide cylinder extends into the interior of the outer mesh cylinder and is fixedly connected to the right end of the inner mesh cylinder.

[0013] Preferably, the mesh diameter of the inner mesh cylinder is larger than that of the outer mesh cylinder.

[0014] Preferably, the material guiding assembly includes a first inclined plate, a second inclined plate, and a third inclined plate, which are respectively fixedly installed on the inner wall of the screening box.

[0015] Preferably, the air outlet of the fan is located between the first inclined plate and the second inclined plate.

[0016] Preferably, the end of the feed pipe away from the screening box is connected to the interior of the second support frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a rotary drum screening structure, the camellia seeds to be screened are placed in the inner screen drum. Then, the drive component drives the screening drum to rotate, thereby intercepting large particles of impurities in the inner screen drum. Camellia seeds and impurities of the same size as camellia seeds will pass through the mesh on the inner screen drum into the outer screen drum. Impurities smaller than camellia seeds will be filtered through the outer screen drum. Camellia seeds and impurities of the same size as camellia seeds will be intercepted in the outer screen drum. Then, the camellia seeds and impurities in the outer screen drum will enter the screening box along the feed pipe, and the camellia seeds and impurities of the same size as camellia seeds will be screened by wind power, which improves the screening quality and avoids the defect of incomplete screening.

[0019] 2. By setting up a wind-powered screening structure, after the rotary drum screening structure conveys tea oil seeds and impurities compatible with tea oil seeds into the screening box, the fan generates airflow to blow the tea oil seeds and impurities of the same size as the tea oil seeds. Since the tea oil seeds and impurities of the same size as the tea oil seeds have different specific gravities, the impurities of the same size as the tea oil seeds can be blown onto the second inclined plate, while the tea oil seeds will fall onto the third inclined plate, thereby improving the screening quality.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-4This utility model provides a technical solution: a camellia seed screening device, including: a rotary drum screening structure and a wind-powered screening structure.

[0028] The rotary drum screening structure includes a first support frame 10, a second support frame 11, a screening cylinder rotatably connected to the inner walls of the first support frame 10 and the second support frame 11, and a drive assembly disposed on the surface of the second support frame 11 for driving the screening cylinder to rotate.

[0029] The screening cylinder consists of an inner cylinder 30 and an outer cylinder 32 fixedly installed on the outer surface of the inner cylinder 30 by a support rod 31. The surface of the outer cylinder 32 is rotatably connected to the inner walls of the first support frame 10 and the second support frame 11, respectively. The mesh diameter of the inner cylinder 30 is larger than that of the outer cylinder 32. When the outer cylinder 32 rotates, the inner cylinder 30 will rotate synchronously.

[0030] The drive assembly includes a guide cylinder 40 rotatably mounted on the inner wall of the second support frame 11, a first sprocket 41 fixedly mounted on the outer surface of the guide cylinder 40, a motor 42 fixedly mounted on the surface of the second support frame 11, and a second sprocket 43 fixedly mounted on the output end of the motor 42. The first sprocket 41 and the second sprocket 43 are connected by chain drive. The left end of the guide cylinder 40 extends into the interior of the outer mesh cylinder 32 and is fixedly connected to the right end of the inner mesh cylinder 30. The drive motor 42 can drive the second sprocket 43 to rotate, and the chain drive can drive the first sprocket 41 to rotate, thereby driving the guide cylinder 40 and the outer mesh cylinder 32 to rotate synchronously.

[0031] The camellia seeds to be screened are placed in the inner screen cylinder 30. Then, the drive motor 42 drives the screen cylinder to rotate using the drive assembly, thereby intercepting large particles of impurities in the inner screen cylinder 30. Camellia seeds and impurities of the same size as camellia seeds will pass through the mesh on the inner screen cylinder 30 and enter the outer screen cylinder 32. Impurities smaller than camellia seeds can be filtered through the outer screen cylinder 32. Camellia seeds and impurities of the same size as camellia seeds will be intercepted in the outer screen cylinder 32. As the screen cylinder rotates, it will drive the large particles of impurities in the inner screen cylinder 30 to be discharged along the guide cylinder 40. Camellia seeds and impurities of the same size as camellia seeds in the outer screen cylinder 32 will enter the second support frame 11.

[0032] The wind-powered screening structure includes a screening box 20, a fan 21 fixedly installed on the back of the screening box 20, a feed pipe 22 fixedly installed on the front of the screening box 20, a material guiding component set inside the screening box 20, and a slag discharge port 23 and a material discharge port 24 respectively opened on the front and back of the screening box 20. The end of the feed pipe 22 away from the screening box 20 is connected to the interior of the second support frame 11. When tea oil seeds and impurities of the same size as tea oil seeds enter the second support frame 11, the tea oil seeds and impurities of the same size as tea oil seeds will enter the screening box 20 along the feed pipe 22.

[0033] The material guiding assembly includes a first inclined plate 50, a second inclined plate 51, and a third inclined plate 52, which are respectively fixedly installed on the inner wall of the screening box 20. The first inclined plate 50 is above the second inclined plate 51, and the first inclined plate 50 and the second inclined plate 51 are inclined in opposite directions. The front of the third inclined plate 52 is fixedly connected to the back of the second inclined plate 51, and the air outlet of the blower 21 is located between the first inclined plate 50 and the second inclined plate 51.

[0034] When tea oil seeds and impurities of the same size as tea oil seeds enter the screening box 20, the first inclined plate 50 guides and disperses them. When the tea oil seeds and impurities of the same size as tea oil seeds detach from the first inclined plate 50 due to gravity, the driving fan 21 generates airflow to blow the tea oil seeds and impurities of the same size as tea oil seeds. Since the tea oil seeds and impurities of the same size as tea oil seeds have different specific gravities, the impurities can be blown onto the second inclined plate 51 and discharged along the slag discharge port 23. The tea oil seeds will fall onto the third inclined plate 52 and be discharged along the discharge port 24, thereby improving the screening quality and avoiding the defect of incomplete screening.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
