Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 In this embodiment of the utility model, a rose tea sieving machine includes a sieving assembly 1 consisting of a base frame 101, vibration springs 102, connecting seats 103, a sieve box 104, and a sieve plate 105. Four vibration springs 102 are provided. Four connecting seats 103 are connected to the top of the base frame 101 through the four vibration springs 102. The sieve box 104 is fixed to the inner side of the four connecting seats 103. The sieve plate 105 is fixed to the inner side of the sieve box 104. An upper discharge port 106 is fixed at the bottom outlet of the sieve plate 105. A lower discharge port 107 is fixed at the bottom outlet of the sieve box 104. The lower discharge port 107 and the upper discharge port 106 are staggered. A vibration motor 108 is installed at the bottom of the sieve box 104.

[0030] A back-blowing anti-clogging component 2 is provided on the outside of the screen box 104, extending to the inside of the screen box 104 and located below the screen plate 105. The back-blowing anti-clogging component 2 is used to perform back-blowing operation on the screen holes of the screen plate 105.

[0031] The back-blowing anti-clogging component 2 includes a back-blowing unit and a swing drive unit. The back-blowing unit is used to back-blow the rosebuds stuck in the sieve holes, thereby avoiding sieve hole clogging. The swing drive unit is used to drive the back-blowing unit to swing back and forth, thereby increasing the back-blowing area of ​​the back-blowing unit.

[0032] The reverse jet unit includes a jet pipe 201, a nozzle 202, and a flexible connecting pipe 203;

[0033] The blowpipe 201 is rotatably connected to the inside of the screen box 104 and located below the screen plate 105. Multiple nozzles 202 are fixed to the outside of the blowpipe 201 and communicate with the inner cavity of the blowpipe 201. One side of the blowpipe 201 extends through to the outside of the screen box 104 and is connected to the flexible connecting pipe 203. The flexible connecting pipe 203 is connected to an external air pump through a solenoid valve.

[0034] Multiple nozzles 202 are evenly arranged along the long side of the blow pipe 201, and the distribution pattern of the nozzles 202 is the same as the horizontal distribution pattern of the sieve holes on the sieve plate 105.

[0035] High-pressure air is delivered to nozzle 202 by an external air pump to achieve a reverse blowing operation on the screen holes of sieve plate 105.

[0036] The swing drive unit includes a gear 204, a toothed plate 206, a connecting plate 207, and a pneumatic push rod 208;

[0037] The side of the blowpipe 201 away from the flexible connecting pipe 203 extends to the other side of the screen box 104 and is fixedly connected to the gear 204.

[0038] The pneumatic push rod 208 is installed on the outside of the other side of the screen box 104. The output end of the pneumatic push rod 208 is connected to the toothed plate 206 through the connecting plate 207. The toothed plate 206 meshes with the gear 204.

[0039] The pneumatic push rod 208 reciprocates to drive the gear 204 and the spray pipe 201 to reciprocate, thereby increasing the spray range of the nozzle 202;

[0040] Multiple sets of blow pipe 201, nozzle 202, flexible connecting pipe 203, and gear 204 are evenly arranged along the inclined direction of screen box 104, and toothed plate 206 meshes synchronously with multiple sets of gears 204.

[0041] In this embodiment: When screening rosebuds, the rosebuds are manually or by conveyor to the screen plate 105. At this time, the vibration motor 108 is started simultaneously. The vibration motor 108 causes the screen box 104 and the screen plate 105 to vibrate as a whole. The vibration force causes the rosebuds to slide down and vibrate along the inclined surface of the screen plate 105. Among them, the rosebuds smaller than the screen hole diameter of the screen plate 105 fall to the bottom of the screen box 104 and are then discharged from the lower discharge port 107. The rosebuds larger than the screen hole diameter of the screen plate 105 are discharged from the upper discharge port 106, thus completing the screening operation of the rosebuds.

[0042] During this process, rosebuds may get stuck inside the sieve holes. At this time, the external air pump and the solenoid valve connected to the flexible connecting pipe 203 can be activated. The external air pump delivers high-pressure air to the blow pipe 201 and finally sprays it out through the nozzle 202. When the nozzle 202 is aligned with the sieve holes, the airflow can blow the rosebuds stuck in the sieve holes out in the opposite direction, thereby relieving the blockage of the sieve holes.

[0043] At the same time, the pneumatic push rod 208 can be controlled to reciprocate, thereby driving the toothed plate 206 to move back and forth. The toothed plate 206 drives the gear 204 and the blowpipe 201 to rotate back and forth, causing the nozzle 202 on the blowpipe 201 to swing back and forth, thereby enabling the nozzle 202 on a single blowpipe 201 to be aligned with multiple screen holes, thus increasing the back-blowing range.

[0044] Please refer to this carefully. Figures 1-4 The swing drive unit also includes a fixed guide rail 205, which is fixed to the outer wall of the other side of the screen box 104. The toothed plate 206 is slidably connected to the toothed plate 206. The fixed guide rail 205 is used to provide support and guidance for the movement of the toothed plate 206.

[0045] In this embodiment: the fixed guide rail 205 provides support for the movement of the toothed plate 206, ensuring the stability of the movement of the toothed plate 206. It should also be noted that: each of the multiple flexible connecting pipes 203 can be connected to a solenoid valve. By controlling the intermittent opening and closing of the multiple solenoid valves, the position and frequency of the back-jet blowing can be controlled.

[0046] 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 within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
