[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a stem and leaf separation device for matcha production, including a working frame 1, and a top cover is installed at the top of the working frame 1;

[0023] Movable separation frame plates 2 are movably installed at the upper and middle parts of the inner cavity of the working frame 1, and separation sieve plates 3 are installed at the middle parts of the bottoms of the movable separation frame plates 2;

[0024] Dual-frequency processing mechanism 5, the dual-frequency processing mechanism 5 includes a first ejector rod 501 and a second ejector rod 503. The middle part on the right side of the upper movable separation frame plate 2 is installed with the first ejector rod 501, the right side of the middle movable separation frame plate 2 is installed with the second ejector rod 503, and the right sides of the first ejector rod 501 and the second ejector rod 503 both pass through the working frame 1 and extend outside the working frame 1;

[0025] Movable installation mechanism 6, the movable installation mechanism 6 includes an installation telescopic rod 603, and installation telescopic rods 603 are installed at the bottom ends around the outside of the movable separation frame plate 2.

[0026] The dual-frequency processing mechanism 5 further includes a fixed cover frame 502, a moving inclined block 504, a pushing inclined block 505, a first turntable 506, a single-phase motor 507, and a second turntable 508. The fixed cover frame 502 is installed at the right bottom end of the working frame 1. At the right bottom end inside the fixed cover frame 502, a single-phase motor 507 is installed through a mounting seat. A rotating rod is installed at the output end of the single-phase motor 507. The single-phase motor 507 is equipped with a switch. The first turntable 506 is installed on the right side of the middle part of the rotating rod, and the second turntable 508 is installed on the left side of the middle part of the rotating rod. A number of pushing inclined blocks 505 are equidistantly installed around the outer circumference of the first turntable 506 and the second turntable 508. Moving inclined blocks 504 are installed at the bottom ends of the first ejector rod 501 and the second ejector rod 503. The inclined surface of the moving inclined block 504 is in contact with the inclined surface of the pushing inclined block 505. In this way, when separating the tea leaves and tea stalks of matcha, the single-phase motor 507 is started to drive the first turntable 506 and the second turntable 508 to rotate simultaneously. When the first turntable 506 and the second turntable 508 rotate, the surrounding pushing inclined blocks 505 are driven to rotate, so that the inclined surface of the pushing inclined block 505 is in contact with the inclined surface of the moving inclined block 504, and the moving inclined block 504 is pushed to move upward, then the first ejector rod 501 and the second ejector rod 503 are driven to move upward, and the movable separation frame plate 2 is driven to move upward. When the pushing inclined block 505 and the moving inclined block 504 are separated, the first ejector rod 501 and the second ejector rod 503 lose their restraint force, so the first ejector rod 501, the second ejector rod 503, and the movable separation frame plate 2 move downward. The operation is cycled in turn and the movable separation frame plate 2 is driven to move continuously. Since the size of the first turntable 506 is larger than that of the second turntable 508, the rotation speed of the first turntable 506 is lower than that of the second turntable 508, so the vibration frequency of the second ejector rod 503 and the movable separation frame plate 2 at the bottom end is higher;

[0027] The size of the first turntable 506 is larger than that of the second turntable 508. An activity notch is opened at the relative positions of the first ejector rod 501 and the second ejector rod 503 in the middle of the right side of the working frame 1. The first ejector rod 501 and the second ejector rod 503 are both in an inverted L-shaped structure. In this way, through the activity notch, the right sides of the first ejector rod 501 and the second ejector rod 503 can extend to the outside of the working frame 1;

[0028] The movable installation mechanism 6 further includes a universal joint 601 and a return spring 602. Universal joints 601 are installed at the ends of the installation telescopic rods 603 away from the movable separation frame plate 2. The universal joints 601 are connected to the inside of the working frame 1. Return springs 602 are sleeved and installed outside the installation telescopic rods 603. In this way, when the movable separation frame plate 2 moves upward, the installation telescopic rods 603 are driven to expand and contract. When the installation telescopic rods 603 expand and contract, the return springs 602 are driven to stretch. Later, the installation telescopic rods 603 and the movable separation frame plate 2 are driven to reset by the stretched return springs 602;

[0029] The reset springs 602 are all made of spring steel. There is a gap between the outer periphery of the movable separation frame plate 2 and the inner cavity of the working frame 1, so that the elasticity and service life of the reset springs 602 during use are increased by the spring steel material;

[0030] The movable separation frame plate 2 is in a funnel-shaped structure. A discharge head is installed at the bottom end of the working frame 1. Sealing sleeves 4 are installed around the top end of the movable separation frame plate 2. The top end of the sealing sleeve 4 is connected to the inner cavity of the working frame 1. In this way, the sealing performance between the movable separation frame plate 2 and the inner cavity of the working frame 1 during the moving process is increased through the sealing sleeve 4, and it does not prevent the normal operation of the movable separation frame plate 2.

[0031] Working principle: When the present utility model separates the tea leaves and tea stalks of matcha, start the single-phase motor 507 to drive the first turntable 506 and the second turntable 508 to rotate at the same time. When the first turntable 506 and the second turntable 508 rotate, drive the surrounding push inclined blocks 505 to rotate, so that the inclined surface of the push inclined block 505 contacts the inclined surface of the moving inclined block 504, and push the moving inclined block 504 to move upward, then drive the first ejector rod 501 and the second ejector rod 503 to move upward, and drive the movable separation frame plate 2 to move upward. When the push inclined block 505 and the moving inclined block 504 are separated, the first ejector rod 501 and the second ejector rod 503 lose their restraint force, then the first ejector rod 501, the second ejector rod 503 and the movable separation frame plate 2 move downward, and the operation is cycled in turn and drives the movable separation frame plate 2 to move continuously. Since the size of the first turntable 506 is larger than that of the second turntable 508, the rotation speed of the first turntable 506 is lower than that of the second turntable 508, so the vibration frequency of the second ejector rod 503 and the movable separation frame plate 2 at the bottom end is higher. During the process of separating the tea leaves, the double-layer processing can separate more thoroughly, and different frequencies are used for separation processing, and different grades of tea leaves can be separated simultaneously during the processing, avoiding using the same frequency and only one separation end for processing during the processing, which will not only reduce the efficiency of later processing and separation, but even require rework later, increasing the processing cost.
