Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, specifically relating to a tea seed screening device for oil extraction from tea seeds. Background Technology

[0002] Camellia seeds can be used to extract oil, and the finished product is called tea oil. Compared with rapeseed oil and peanut oil, its market share is low, but it has its unique edible value. In order to ensure the quality of the extracted oil, screening equipment is needed to sort the camellia seeds when processing them for oil extraction of different sizes.

[0003] For example, a Chinese patent discloses a tea seed screening device for pressing tea seeds for oil extraction (publication number CN221493177U), which includes a cylindrical screening box, a rotating shaft rotatably arranged inside the screening box, a sieve plate arranged inside the screening box, a rotating arm fixedly connected to the peripheral wall of the rotating shaft, the rotating arm being perpendicular to the rotating shaft, and connecting rods fixedly connected to the bottom of both ends of the rotating arm, the connecting rods being vertically arranged.

[0004] However, the pull-out sieve plate in the aforementioned public documents is convenient for cleaning. A cleaning rod and brush sweep away branches and leaves stuck in the sieve holes, ensuring unobstructed flow. However, in practice, this patent only allows for preliminary screening of camellia seeds, resulting in low screening efficiency and potentially incomplete screening, leading to inconsistent seed diameters and affecting the quality of subsequent oil extraction. Therefore, those skilled in the art have provided a solution to address the problems mentioned in the background section. Utility Model Content

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1 As shown, a tea seed screening device for oil extraction from tea seeds includes a support 1. A screening box 2 is fixedly installed on the outer top surface of the support 1. Mounting plates 16 are fixed on the outer walls of both sides of the support 1. Two mounting plates 16 are symmetrically provided with through-hole screw holes 17. Tightening the fastening bolts in the screw holes 17 can fix the mounting plates 16 in a designated area, thereby ensuring the stability of the device in subsequent operation and facilitating disassembly and assembly later.

[0025] like Figure 1 and Figure 3 As shown, the screening box 2 has symmetrically arranged sorting chambers 3 inside. A screen cylinder 4 is rotatably installed inside both sorting chambers 3. The two ends of the screen cylinder 4 extend rotatably to the left and right outer walls of the screening box 2. The left and right ends of the outer circumferential sidewall of the screen cylinder 4 have through-holes 5 and 6 arranged in a circular array. A spiral conveying blade 7 is rotatably installed on the inner circumferential sidewall of the screen cylinder 4. First, the camellia seeds to be screened are placed into the inside of the screen cylinder 4, and the screen cylinder 4 is driven to rotate. During the circumferential rotation, with the assistance of the conveying blade 7, the camellia seeds can be driven to move along the input end to the output end of the screen cylinder 4. Simultaneously, the aperture of the first screen hole 5 is larger than that of the second screen hole 6. Therefore, camellia seeds with smaller particle sizes are first screened by the second screen hole 6, while larger camellia seeds are screened by the first screen hole 5. The largest camellia seeds are discharged and collected along the screen cylinder 4, thus achieving the effect of separating and screening camellia seeds of different particle sizes, improving practicality.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the support 1 has two symmetrically arranged sorting chambers 8 inside. Each of the two sorting chambers has a sieve plate 9 and a sieve plate 10 inside. A guide hole 11, communicating with the sorting chamber 8, is located at the center of the bottom surface of each of the two sorting chambers 8. The left end of the front outer wall of the support 1 has two openings, one 14 and one 141, communicating with one of the sorting chambers 8. A rotatable sealing plate 142 is rotatably installed inside the opening 14. The right end of the rear outer wall of the support 1 has two openings, one 143 and one 144, communicating with the other sorting chamber 8. A rotatable sealing plate 142 is rotatably installed inside the opening 143. Equipped with an openable and closable sealing plate 145, the camellia seeds initially screened by the sieve cylinder 4 enter the sorting chamber 8 through the guide holes 11. They undergo secondary screening on the sieve plate 9 and the screening plate 2. The aperture of the sieve plate 9 is larger than that of the sieve plate 2 10, so larger particles are intercepted on the sieve plate 9 and the sieve plate 2 10, while smaller particles are discharged through the openings 141 and 144. After screening, the sealing plates 142 and 145 are opened to remove the camellia seeds from the sieve plates 9 and 2 10, thus ensuring thorough screening of the camellia seeds and ensuring the quality of subsequent oil extraction.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a linkage assembly 12 for synchronously screening the screen cylinder 4, screen plate 9, and screen plate 10 is provided on the right outer wall of the screening box 2. The linkage assembly 12 includes a rotating shaft 121 rotatably installed inside the screening box 2. An external gear ring 122 is fixedly installed on the left end of the outer peripheral side wall of the screen cylinder 4 outside the screening box 2. One end of the rotating shaft 121 rotatably extends to the left outer side of the screening box 2, and a gear 123 is fixedly installed on the outer peripheral side wall. The other end rotatably extends to the right outer side of the screening box 2, and a pulley 124 is fixedly installed on the outer peripheral side wall. The gear 123 is located below the external gear ring 122. Furthermore, the two are meshed together. A rotating shaft 125 is rotatably mounted inside the support 1. One end of the rotating shaft 125 extends rotatably to the outer right side of the support 1, and a pulley 126 is fixedly mounted on its outer periphery. Pulleys 124 and 126 are meshed together via a toothed belt 127. Lifting blocks 13 are fixedly mounted at the center of the outer bottom surface of both screen plates 9 and 10. Eccentric wheels 131 are fixedly mounted inside the two sorting chambers 8 and on the outer periphery of the rotating shaft 125. The two eccentric wheels 131 abut against the two lifting blocks 13. The inner walls of the two sorting chambers 8 are... Sliding sleeves 132 are bolted to the sides, and sliding rods 133 are slidably connected inside the sliding sleeves 132. One end of the sliding rods 133 is fixedly connected to the outer bottom surface of screen plate 9 and screen plate 10 respectively by bolts (the threaded connection of the bolts facilitates subsequent disassembly and assembly). A drive motor 15 is fixedly installed on the right outer wall of the screening box 2, corresponding to the rotating shaft 121. The output end of the drive motor 15 is fixedly connected to the rotating shaft 121. In use, the controller controls and starts the drive motor 15 to drive the rotating shaft 121 to rotate with the gear 123 and pulley 124. Under the combined connection characteristics, the external toothed ring 122 drives the sieve cylinder 4 to rotate circumferentially. At the same time, under the transmission characteristics of the toothed belt 127, the pulley 126 drives the rotating shaft 125 to rotate synchronously. This drives the eccentric wheel 131 to push the lifting block 13 to lift the sieve plate 9 and the sieve plate 10, allowing the slide rod 133 to slide inside the sliding sleeve 132. Under the elastic extension and contraction of the return spring sleeved outside the slide rod 133, the slide rod 133 can be reset. This cycle generates a vibration effect, allowing the sieve plate 9 and the sieve plate 10 to screen tea seeds, achieving a linkage effect, reducing the power source, lowering operating costs, and thus improving practicality.

[0028] The working principle of this utility model is as follows: During use, the drive motor 15 is first started to drive the rotating shaft 121 and rotating shaft 125 to rotate synchronously, thereby driving the sieve cylinder 4, sieve plate 9, and sieve plate 10 to operate synchronously. Then, the camellia seeds to be sieved are placed into the sieve cylinder 4, where they undergo preliminary sorting through sieve holes 5 and 6. Simultaneously, the preliminarily sorted camellia seeds flow along the guide holes 11 from the sorting chamber 3 into the sorting chamber 8, and fall onto the outer top surfaces of sieve plates 9 and 10 for secondary sorting. Finally, the seeds are further sorted along the open... The oil is discharged through outlets 143 and 144, ensuring more thorough screening of camellia seeds, facilitating subsequent oil extraction and improving oil quality. (It should be noted that all electrical components mentioned in this article are electrically connected to an external power source, and the control method in this invention is controlled by a PLC controller. The control circuit of the PLC controller can be implemented by those skilled in the art through programming, and thus can operate normally according to the above steps. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.)

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
