Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a tea shaking and sieving machine. Background Technology

[0002] The vibrating sieve machine is a key piece of equipment in the refining and processing of tea leaves. It is mainly used to separate tea leaves by length and thickness, and to classify the tea leaves into grades. Its working principle is that a vibration generator drives the sieve frame and sieve mesh to vibrate at high frequency. The tea leaves jump and move forward on the sieve mesh. The fine tea leaves fall through the sieve holes, while the coarser tea leaves continue to move forward along the sieve surface, thereby achieving sorting.

[0003] In actual production, fine tea dust and buds easily clog the sieve mesh, severely reducing screening efficiency and product quality. Traditional cleaning methods mainly rely on manual cleaning with brushes after the machine stops, which is not only labor-intensive and inefficient, but also significantly impacts production continuity and automation due to downtime for cleaning. Although some online cleaning devices exist, most have simple structures, limited cleaning effects, and their cleaning components are prone to wear and have short service lives. Utility Model Content

The sieve frame is provided with a screen located at its bottom. The frame is provided with a lifting and adjusting mechanism. The lifting and adjusting mechanism is connected to an adjusting frame located below and parallel to the sieve frame. The side of the adjusting frame is provided with a reciprocating drive mechanism. The reciprocating drive mechanism is connected to a reciprocating rod located inside the adjusting frame. The reciprocating rod is provided with multiple sets of elastic cleaning mechanisms and roller brush cleaning mechanisms evenly distributed along its axial direction.

[0008] More preferably, the roller brush cleaning mechanism includes a support member fixedly connected to the reciprocating rod and arranged radially thereon, and a cleaning brush roller rotatably connected to the support member. The support member is provided in two sets and is close to both ends of the reciprocating rod.

[0009] More preferably, the elastic cleaning mechanism and the roller brush cleaning mechanism are arranged on opposite sides.

[0010] More preferably, the reciprocating rod includes a sliding part located on both sides and slidably engaged with the adjustment frame, and a bearing part rotatably connected to the sliding part. The bearing part is provided with an adjustment component that can drive the sliding part to rotate.

[0011] More preferably, a transmission cavity is provided in one side of the sliding part, and one end of the bearing part is coaxially connected to a transmission shaft extending into the transmission cavity. The adjusting component includes a transmission worm gear tooth disposed on the transmission shaft, a transmission worm rotatably disposed in the transmission cavity and meshing with the transmission worm gear tooth, and a driving member fixed on the sliding part and capable of driving the transmission worm to rotate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The overall height and angle of the cleaning components are adjustable, which can not only adapt to screens with different mesh sizes, but also compensate for wear by adjusting the angle to maintain the best cleaning effect and reduce maintenance costs.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] This utility model provides an embodiment, such as Figure 1 , Figure 2 As shown, a tea shaking and sieving machine includes a frame 1, a sieve frame 2 connected to the frame 1 by an elastic element, and a vibration generator set on the sieve frame 2. In this embodiment, the vibration generator is a vibration motor. The sieve frame 2 is provided with a screen 201 located at its bottom, and the screen 201 is set horizontally.

[0024] The frame 1 is provided with a lifting adjustment mechanism 3. In this embodiment, the lifting adjustment mechanism 3 is an electric push rod. The lifting adjustment mechanism 3 is connected to an adjustment frame 4 located below and parallel to the screen frame 2. The lifting adjustment mechanism 3 can drive the adjustment frame 4 to rise and fall vertically as a whole. The side of the adjustment frame 4 is provided with a reciprocating drive mechanism 5. The reciprocating drive mechanism 5 is connected to a reciprocating rod 6 located inside the adjustment frame 4. The reciprocating rod 6 is provided with multiple sets of elastic cleaning mechanisms 7 and roller brush cleaning mechanisms 8 evenly distributed along its axial direction.

[0025] The lifting and adjusting mechanism 3 can drive the entire adjusting frame 4 and its cleaning components to rise and fall, allowing the elastic cleaning mechanism 7 or the roller brush cleaning mechanism 8 to contact or separate from the bottom surface of the screen 201, thus turning the cleaning mode on and off. The reciprocating drive mechanism 5 drives the reciprocating rod 6 and its cleaning components to reciprocate along the width direction of the screen 201.

[0026] When the screen frame 2 vibrates, the elastic cleaning mechanism 7 continuously impacts and wipes the bottom surface of the screen mesh 201, providing additional, uninterrupted cleaning power to prevent blind holes and adhesion.

[0027] Specifically, such as Figure 3 As shown, the elastic cleaning mechanism 7 includes a column 710 fixedly connected to the reciprocating rod 6 and arranged radially thereon, and an elastic ball 720 fixed at the end of the column 710 and capable of contacting the screen 201. In this embodiment, the elastic ball 720 is a silicone ball.

[0028] To provide sufficient elastic cushioning effect, in a further embodiment, the column 710 includes a fixed part 711 fixedly connected to the reciprocating rod 6, a movable hole 712 provided on the fixed part 711, and a movable part 714 extending into the movable hole 712 and connected to it through an elastic component 713. The movable part 714 can slide axially within the movable hole 712, and the elastic ball 720 is rotatably disposed on the movable part 714.

[0029] This structure constitutes a dual elastic buffer system, which not only ensures effective contact between the elastic ball 720 and the screen 201, but also buffers the impact of vibration, protecting the screen 201 and the elastic ball 720 and extending their service life.

[0030] Specifically, such as Figure 2 As shown, the roller brush cleaning mechanism 8 includes a support member 801 fixedly connected to the reciprocating rod 6 and arranged radially thereon, and a cleaning brush roller 802 rotatably connected to the support member 801. The support member 801 is provided in two sets and is close to both ends of the reciprocating rod 6.

[0031] The elastic cleaning mechanism 7 and the roller brush cleaning mechanism 8 are arranged on opposite sides. When the mechanism on one side performs cleaning, the mechanism on the other side returns to its empty position, avoiding interference and making the structure compact.

[0032] To improve the adaptability of the cleaning mechanism, in a further embodiment, the reciprocating rod 6 includes a sliding part 601 located on both sides and slidably engaged with the adjustment frame 4, and a bearing part 602 rotatably connected to the sliding part 601. The bearing part 602 is provided with an adjustment component 610 that can drive the sliding part 601 to rotate.

[0033] The component 610 can be adjusted to drive the bearing 602 and all the cleaning mechanisms installed on it to rotate as a whole by a certain angle, thereby changing the contact posture and contact force between the cleaning mechanism and the screen 201, adapting to different cleaning needs or compensating for wear.

[0034] Specifically, a transmission cavity 603 is provided in the sliding part 601 on one side, and a transmission shaft 604 extending into the transmission cavity 603 is coaxially connected to one end of the bearing part 602. The adjusting component 610 includes a transmission worm gear 611 disposed on the transmission shaft 604, a transmission worm 612 rotatably disposed in the transmission cavity 603 and meshing with the transmission worm gear 611, and a driving member 613 fixed on the sliding part 601 and capable of driving the transmission worm 612 to rotate.

[0035] The worm gear drive has a self-locking function, which can automatically lock the angle after adjustment to prevent deflection in a vibrating environment and ensure the stability of the working state.

[0036] To improve the stability of the reciprocating rod 6 during movement, in a further embodiment, the inner side of the adjustment frame 4 is provided with a sliding groove 401, and the sliding part 601 extends into the sliding groove 401 and slides therewith. The sliding part 601 is provided with a transmission screw hole 605. The reciprocating drive mechanism 5 includes a drive screw 501 disposed in the sliding groove 401 and meshing with the transmission screw hole 605, and a power component 502 fixed outside the adjustment frame 4 and transmittedly connected to the drive screw 501. In this embodiment, the power component 502 is a servo motor that can rotate in both directions.

[0037] The screw drive is smooth and precise, providing sufficient driving force to drive the reciprocating rod 6 and the cleaning mechanism to reciprocate stably.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
