[0002] Camellia oleifera is a high-grade oil crop unique to China and one of the four major woody oil crops in the world. Camellia oleifera fruits need to be shelled before oil extraction. However, the traditional manual shelling not only requires long-term drying and stacking, but also causes the quality of tea oil to deteriorate during the process. Mechanized shelling of camellia oleifera fruits can save manpower and material resources and is not affected by weather. Common mechanical shelling methods include impact, rubbing, and squeezing.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1 , Figure 2 As shown, the oil tea fruit cutting and extruding shelling machine of the present invention is mainly composed of a frame 1, a hopper 2, a grading device 3, a cutting and extruding device 4, a shell-seed separation device 5, a Y100L1-4 three-phase asynchronous motor 6, and a Y100L2-4 three-phase asynchronous motor 7.

[0037] The feed hopper 2 is located at the upper right of the frame 1, and the lower part of the feed hopper 2 is connected to one end of the grading device 3. Four groups of cutting and extruding devices 4 are arranged below the grading device 3, and the lower part of the cutting and extruding device 4 is a shell-seed separation device 5. A Y100L1-4 three-phase asynchronous motor 6 and a Y100L2-4 three-phase asynchronous motor 7 are arranged at the lowermost part. The two motors constitute a transmission system that provides power for the grading device 3, the cutting and extruding device 4 and the shell-seed separation device 5, and provide power for the entire tea fruit cutting and extruding shelling machine.

[0038] like Figure 3 As shown, the grading device 3 of the present invention is installed above the frame 1, and is mainly composed of a grading shaft 301, a grading rubber belt 302, a collecting tank 303 and a collecting tank through hole 304. There are two grading shafts 301, which are at both ends of the grading rubber belt 302 and have a height difference, driving the grading rubber belt 302 to rotate. The grading shaft 301 and the collecting tank 303 are installed on the frame 1. During the rotation of the grading device 3, the oil tea fruit will fall into the corresponding collecting tank 303 according to different fruit diameters due to its own gravity and the friction with the grading rubber belt 302, thereby achieving oil tea fruit grading.

[0039] The grading rubber belt 302 is composed of seven rubber belts that are narrow in front and wide in the back. The grading rubber belt 302 of the grading device 3 is installed in a way that it is narrow in front and wide in the back, and corresponds to the collecting slot 303 below. There are four collecting slots 303, which collect oil tea fruits of different fruit diameter ranges. The gap of the grading rubber belt corresponding to the first collecting slot is 20-25mm, the gap of the grading rubber belt corresponding to the second collecting slot is 25-30mm, the gap of the grading rubber belt corresponding to the third collecting slot is 30-35mm, and the gap of the grading rubber belt corresponding to the fourth collecting slot is 35-40mm. The oil tea fruits of different fruit diameters can be graded and made to fall into the corresponding collecting slot 303. The collecting slot through hole 304 is located below each collecting slot 303. Under the action of the gravity of the oil tea fruit itself and the friction with the grading rubber belt 302, the oil tea fruit moves forward along with the grading rubber belt 302 after entering the device from the feed hopper 2. During this process, the smaller tea fruits will fall in the smaller gap in front of the grading rubber belt 302, while the larger tea fruits will fall in the larger gap in the rear of the grading rubber belt 302. Tea fruits of different diameters fall into the corresponding collecting troughs 303, and the tea fruits are divided into 20-25mm, 25-30mm, 30-35mm and 35-40mm in turn. Finally, the tea fruits in the collecting trough 303 enter the cutting and squeezing device 4 through the collecting trough through hole 304. The feed hopper 2 is located above the front of the grading rubber belt 302.

[0040] like Figures 4 to 6As shown, the slicing and extruding device 4 of the present invention is installed in the middle of the frame 1, and is mainly composed of an extrusion outer roller 401, a transmission shaft 402, a slicing tool 403, a slicing outer cylinder 404, an extrusion outer cylinder 405, an extrusion inner plate 406, a slicing inner cylinder 407, a spiral blade 408, an extrusion main roller 409, an extrusion spring 410, an extrusion sub-roller 411, a slicing spring 412, a slicing guide rod 413 and an adjusting nut 414. There are 4 groups of slicing and extruding devices, which correspond to the collecting tank 303 one by one and are installed below it. The slicing and extruding device is divided into two parts: a slicing device and an extrusion device.

[0041] like Figure 4 , Figure 5 As shown, the slicing device of the present invention is mainly composed of an extrusion outer roller 401, a transmission shaft 402, a slicing tool 403, a slicing outer cylinder 404, a slicing inner cylinder 407, a spiral blade 408, a slicing spring 412, a slicing guide rod 413 and an adjusting nut 414. The extrusion outer roller 401 is located obliquely above the outside of the extrusion outer cylinder 404. The slicing device specifically includes an extrusion outer roller 401 installed on the frame 1, a rotatable transmission shaft 402 installed on the frame 1, a slicing inner cylinder 407 and a slicing outer cylinder 404 installed at the rear end of the transmission shaft 402 and coaxially arranged, a slicing tool 403 installed between the slicing inner cylinder 407 and the slicing outer cylinder 404, and a spiral blade 408 installed on the transmission shaft 402 and located in the slicing inner cylinder 407. Among them, the slicing tool 403 is installed on the outer periphery of the slicing inner cylinder 407 through the slicing spring 412, the slicing guide rod 413 and the adjusting nut 414. During the rotation of the cutting device, the oil tea fruit is cut and shelled by the cutting tool 403, and is transported to the extrusion device by the spiral blade 408. The cutting and extrusion device 4 is installed obliquely on the frame 1, and the cutting outer cylinder 404 and the cutting inner cylinder 407 have through holes corresponding to the diameter of the oil tea fruit, so that the oil tea fruit can smoothly enter and exit the cutting and extrusion device 4.

[0042] Inside the extrusion outer cylinder 404 are the scoring tool 403, the scoring inner cylinder 407, the spiral blade 408 and the transmission shaft 402. The scoring tool 403 is connected to the outside of the scoring inner cylinder 407 through the scoring guide rod 413, and is equipped with a scoring spring 412 and an adjusting nut 414, which can score the oil tea fruits of different fruit diameters. The scoring outer cylinder 404 and the scoring inner cylinder 407 are connected to the transmission shaft 402 through a hub, and the spiral blade 408 is directly welded to the transmission shaft 402. The oil tea fruit enters the scoring device through the through hole of the scoring outer cylinder 404. The scoring and shelling are performed under the action of the scoring tool 403 and the scoring inner cylinder 407. After the scoring and shelling, the oil tea fruit enters the interior of the scoring inner cylinder 407 through the through hole on the scoring inner cylinder 407, and is transported to the extrusion device under the action of the spiral blade 408. The cutting tools 403 of each set of cutting devices apply different cutting forces to the tea fruits of corresponding fruit diameters through the cutting springs 412, the cutting guide rods 413 and the adjusting nuts 414 to prevent the tea seeds from being damaged during the cutting process.

[0043] like Figure 4 , Figure 6As shown, the extrusion device of the present invention is mainly composed of a transmission shaft 402, an oil extrusion outer cylinder 405, an extrusion inner plate 406, an extrusion main roller 409, an extrusion spring 410, and an extrusion sub-roller 411. The extrusion device specifically includes an extrusion main roller 409 installed at the front end of the transmission shaft 402, an extrusion sub-roller 411 installed on the extrusion main roller 409, an extrusion outer cylinder 405 connected to the cutting inner cylinder 407 and located outside the extrusion main roller 409, an extrusion spring 410 installed inside the extrusion outer cylinder 405, and an extrusion inner plate 406 connected to the extrusion spring 410. During the rotation process, the extrusion device further extrudes and breaks the shell of the oil tea fruit that has been cut and broken. The extrusion outer cylinder 405 is sequentially provided with an extrusion spring 410, an extrusion inner plate 406, an extrusion sub-roller 411, and an extrusion main roller 409. The extrusion inner plate 406 is connected to the cutting inner cylinder 407. One end of the extrusion spring 410 is connected to the extrusion outer cylinder 405, and the other end of the extrusion spring 410 is connected to the extrusion inner plate 406. The inside of the extrusion main roller 409 is connected to the transmission shaft 402. The diameter of the extrusion main roller 409 gradually increases in the direction away from the slicing device, and 8 extrusion sub-rollers 411 are evenly arranged outside. The extrusion outer cylinder 405 in the extrusion device is welded to the slicing inner cylinder 407 of the slicing device, and the extrusion inner plate 406 is connected to the inside of the pressurized outer cylinder 405 through the extrusion spring 410. The elastic force provided by the extrusion spring 410 in different extrusion devices is different. The extrusion sub-rollers 411 are welded to the extrusion main roller 409 and arranged on the central circumference of the extrusion main roller 409. There are 8 extrusion sub-rollers 411. For tea fruits of different fruit diameters, the radius of each group of extrusion main rollers 409 is different. After the tea fruit enters the extrusion device, it is further squeezed and shelled under the joint action of the extrusion outer cylinder 405, the extrusion inner plate 406 and the extrusion main roller 409. After the shell is crushed, the oil-tea fruit rolls to the right due to its own gravity and falls into the shell-seed separation device 5 because the cutting and squeezing device 4 is tilted.

[0044] like Figure 7As shown, the shell-seed separation device 5 of the present invention is installed below the frame 1, and is mainly composed of a key-type walker 501, a seed sweeping plate 502, a walker crankshaft 503, a seed sweeping plate rotating shaft 504, a separation tooth roller 505, a separation light roller 506, and a tooth light roller rotating shaft 507. The shell-seed separation device 5 specifically includes a walker crankshaft 503 installed on the frame 1, a key-type walker 501 installed on the walker crankshaft 503, a seed sweeping plate rotating shaft 504 installed on the frame 1, a seed sweeping plate 502 installed on the seed sweeping plate rotating shaft 504, a tooth light roller rotating shaft 507 installed on the frame 1, and a separation tooth roller 505 and a separation light roller 506 installed on the tooth light roller rotating shaft 507 and arranged in sequence. Among them, the separation tooth roller 505, the separation light roller 506, and the tooth light roller rotating shaft 507 constitute a tooth light roller separation device. During the up-and-down shaking of the key-type walker 501, the cut and squeezed tea fruit on the key surface of the key-type walker 501 is thrown and sieved for further separation. The key-type walker 51 in the shell-seed separation device 5 shakes up and down under the action of the walker crankshaft 53, and the tea fruit separated from the shell and seed after cutting and squeezing is preliminarily separated through the through holes on the key surface of the key-type walker 51. During the rotation process, the seed sweeping plate 502 sweeps the shell and tea seed of the tea fruit to the feeding end of the toothed roller separation device. During the rotation process, the toothed roller separation device uses the difference in linear speed between the separation toothed roller 505 and the separation light roller 506 and the difference in physical properties between the tea seeds and the shells to complete the separation between the tea seeds and the shells. The key-type walker 501 is located at the top of the shell-seed separation device 5, and below it are the seed sweeping plate 502 and the toothed roller separation device. Driven by the walker crankshaft 503, the key walker 501 shakes up and down, throwing and sifting the cut and squeezed tea fruits on the key surface of the walker crankshaft 503, so that the shell and seeds are initially separated. The seed sweeping plate 502 is located below the key walker 501, and the tea fruits falling from the key walker 501 fall onto the seed sweeping plate 502, and then are swept to the feeding end of the toothed roller separation device.

[0045] like Figures 1 to 8As shown, the transmission system of the present invention is installed at the bottom of the frame 1, and is powered by two motors, Y100L1-4 three-phase asynchronous motor 6 and Y100L2-4 three-phase asynchronous motor 7, mainly through belt transmission and gear transmission. Y100L1-4 three-phase asynchronous motor 6 transmits power to toothed roller shaft 507, seed sweeping plate shaft 504 and draft walker crankshaft 503 through belt transmission, so as to realize the rotation of separation toothed roller 505 and separation light roller 506, the rotation of seed sweeping plate 502 and the sifting movement of key-type draft walker 501, wherein the toothed roller shaft 507 in the toothed roller separation device obtains power through gear transmission. Y100L1-4 three-phase asynchronous motor 6 provides power to the shell-seed separation device 5, and transmits power to toothed roller shaft 507, seed sweeping plate shaft 504 and draft walker crankshaft 503 in turn through belt transmission. Because of the design requirements for the linear speed of the separation tooth roller 505 and the separation light roller 506, gear transmission is used inside the tooth light roller separation device to achieve the rotation of the separation tooth roller 505 and the separation light roller 506, the rotation of the seed sweeping plate 502 and the screening movement of the key-type draft remover 501.

[0046] The Y100L2-4 three-phase asynchronous motor 7 provides power to the grading device 3 and the cutting and squeezing device 4, and transmits the power to the transmission shaft 402 and the grading rotating shaft 301 in turn through the belt drive. The transmission shafts 402 of the four cutting and squeezing devices 4 are belt-driven, and the transmission shaft 402 in the cutting and squeezing device 4 and the squeezing outer roller 401 are gear-driven, so as to realize the transmission of the grading rubber belt 302 and the rotation of the cutting and squeezing device.

[0047] The Y100L2-4 three-phase asynchronous motor 7 transmits power to the transmission shaft 402 and the grading shaft 301 through belt transmission, so as to realize the rotation of the slicing and squeezing device 4 and the transmission of the grading rubber belt 302, wherein the transmission shaft 402 in the slicing and squeezing device 4 transmits power to the squeezing outer roller 401 through gear transmission. In each part, the part with low transmission ratio requirement adopts belt transmission for power transmission, while the part with strict transmission ratio requirement adopts gear transmission for power transmission, for example, the toothed roller shaft 507 in the toothed roller separation device obtains power through gear transmission and the transmission shaft 402 in the slicing and squeezing device 4 transmits power to the squeezing outer roller 401 through gear transmission.

[0048] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
