Description
Technical Field
[0001] This utility model relates to the field of tea cake dust removal technology, specifically a dust removal and cleaning device for jasmine tea cakes. Background Technology
[0002] Jasmine tea base is the core base tea in the jasmine tea scenting process. It refers to raw tea or refined tea that has been processed through specific primary and secondary processing techniques and has the ability to absorb fragrance. When preparing jasmine tea, it is often necessary to clean the tea base to remove dust.
[0003] Traditional equipment often relies solely on screen vibration or simple dust extraction, which cannot achieve graded processing of heavy and light dust. This results in heavy dust residue and light dust dispersion, leading to incomplete dust removal and affecting the subsequent aroma absorption effect of the tea leaves. To address this, we propose a dust removal and cleaning device for jasmine tea leaves. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a dust removal and cleaning device for jasmine tea leaves. This device solves the problem that existing traditional equipment often relies solely on screen vibration or simple dust suction, which cannot achieve graded treatment of heavy and light dust, resulting in heavy dust residue and light dust dispersion, incomplete dust removal, and affecting the subsequent aroma absorption effect of the tea leaves.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal and cleaning device for jasmine tea leaves, comprising a base plate, a hopper above the base plate, a dust removal mechanism on the upper surface of the base plate, the dust removal mechanism including a support plate mounted above the base plate, a protrusion fixedly connected to the lower surface of the hopper, the protrusion being rotatably connected to one side of the support plate, a sieve plate installed on the inner wall of the bottom of the hopper for blocking jasmine flowers, and an arc-shaped limiting sleeve fixedly connected to the upper surface of the base plate. An arc-shaped limiting rod is fixedly connected to one side of the storage compartment. The limiting rod slides against the inner wall of the limiting sleeve. A spring is fixedly connected to the inner wall of the limiting sleeve, and one end of the spring is connected to the limiting rod. The centers of the limiting rod and the limiting sleeve are both on the same straight line as the rotation axis of the protrusion. The intermittent drive of the control motor makes the swing amplitude of the storage compartment controllable. The tea leaves only undergo gentle tumbling and collisions in the storage compartment, avoiding breakage of the tea leaves due to violent impacts. The sieve plate precisely blocks the tea leaves, allowing only dust to pass through, preventing the tea leaves from being lost or damaged by dust.
[0006] Furthermore, two symmetrically arranged mounting strips are fixedly connected to the lower surface of the hopper, and a dust collection tray is inserted into the mounting strip. The dust collection tray is located directly below the screen plate and is connected to the interior of the hopper.
[0007] Furthermore, a stabilizing seat is fixedly connected to the upper surface of the base plate, a control motor is fixedly connected inside the stabilizing seat, a drive wheel is fixedly connected to the drive end of the control motor, and a transmission wheel is rotatably connected to the side of the support plate near the control motor. The shaft of the transmission wheel passes through the support plate and is fixedly connected to the axis of the protrusion.
[0008] Furthermore, a dust collection mechanism is installed above the hopper. The dust collection mechanism includes a protective cover located above the hopper. Guide grooves are provided on both sides of the hopper, and limit strips are fixedly connected to both sides of the protective cover. The limit strips slide into the guide grooves. Two symmetrically arranged diversion hoods are installed on the upper surface of the protective cover. The diversion hoods are connected to the hopper. The protective cover is quickly fastened to the guide grooves through the limit strips. The dust collection tray can be positioned by inserting the installation strip. With the mechanical locking mechanism of the clamp and the stop bar, the components can be assembled and fixed without special tools. During the dust removal process, the control motor automatically realizes intermittent reciprocating vibration without continuous manual intervention. Only the equipment needs to be started and the status monitored.
[0009] Furthermore, a conduit is installed on the upper surface of the diversion hood, and a connector is fixedly connected to the end of the conduit away from the diversion hood. After dust removal is completed, the dust collection tray and protective cover can be removed simply by unlocking the baffle, and the heavy dust can be poured out and the components rinsed directly. There are no complicated dead corners inside the hopper, and the initial cleaning can be completed after the tea cake is taken out. The components are made of food-grade durable materials, which are wear-resistant and easy to clean, reducing the frequency of maintenance and replacement costs, and meeting the hygiene and operation and maintenance requirements of food processing equipment.
[0010] Furthermore, a stop bar is rotatably connected to one side of the hopper, and counterweights are fixedly connected to both sides of one end of the stop bar. Stop blocks are fixedly connected to the sides of the dust collection tray and the protective cover near the stop bar. When the stop bar is in a vertical state, both ends abut against the two stop blocks respectively. The center of the arc-shaped limiting rod and the center of the limiting sleeve coincide with the rotation axis of the protrusion, ensuring precise and unbiased swing trajectory of the hopper. The spring elastic reset mechanism avoids mechanical hard impacts, extending the service life of the components. The stop bar automatically returns to its original position and locks through the counterweights, and with the double fixing of the locking rod, it prevents the protective cover and dust collection tray from loosening during dust removal.
[0011] Furthermore, a sliding groove is provided on the side of the hopper near the stop bar, and a locking rod is slidably connected in the sliding groove. A locking groove is provided on the surface of the stop bar, and the locking rod is adapted to the locking groove.
[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the intermittent drive of the control motor makes the swing amplitude of the hopper controllable, and the tea leaves only undergo gentle tumbling and collision in the hopper, avoiding the breakage of the tea leaves caused by violent impact; the sieve plate precisely blocks the tea leaves, allowing only dust to pass through, preventing the tea leaves from being lost or damaged with the dust.
[0013] 2. In this utility model, the protective cover is quickly fastened to the guide groove by the limiting strip, and the dust collection tray can be positioned by inserting the installation strip. With the mechanical locking mechanism of the clamp and the stop bar, the components can be assembled and fixed without special tools. During the dust removal process, the control motor automatically realizes intermittent reciprocating vibration without the need for continuous manual intervention. It is only necessary to start the equipment and monitor the status.
[0014] 3. In this utility model, the center of the arc-shaped limiting rod and the center of the limiting sleeve coincide with the rotation axis of the protrusion, so that the swing trajectory of the hopper is accurate and without deviation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] refer to Figures 1-7 The device shown is a dust removal and cleaning device for jasmine tea leaves. It includes a base plate 1, a hopper 2 on top of the base plate 1, a dust removal mechanism 3 on the upper surface of the base plate 1, a support plate 33 mounted on top of the base plate 1, a protrusion 38 fixedly connected to the lower surface of the hopper 2, the protrusion 38 being rotatably connected to one side of the support plate 33, a sieve plate 318 installed on the inner wall of the bottom of the hopper 2 to block jasmine flowers, an arc-shaped limiting sleeve 31 fixedly connected to the upper surface of the base plate 1, and an arc-shaped limiting rod 32 fixedly connected to one side of the hopper 2. The limiting rod 32 slides against the inner wall of the limiting sleeve 31. A spring 311 is fixedly connected to the inner wall of the limiting sleeve 31. One end of the spring 311 is connected to the limiting rod 32. The centers of the limiting rod 32 and the limiting sleeve 31 are both on the same straight line as the rotation axis of the protrusion 38. The control motor 35 drives the intermittently so that the swing amplitude of the hopper 2 is controllable. The tea cakes only undergo gentle tumbling and collision in the hopper 2, avoiding the breakage of the tea cakes caused by violent impact. The sieve plate 318 precisely blocks the tea cakes, allowing only dust to pass through, preventing the tea cakes from being lost or damaged by dust.
[0020] The lower surface of the hopper 2 is fixedly connected to two symmetrically arranged mounting strips 39, and a dust collection tray 310 is inserted into the mounting strips 39. The dust collection tray 310 is located directly below the screen plate 318 and is connected to the interior of the hopper 2.
[0021] The base plate 1 has a fixedly connected stabilizing seat 36 on its upper surface. The stabilizing seat 36 has a fixedly connected control motor 35 inside it. The drive end of the control motor 35 has a fixedly connected drive wheel 37. The support plate 33 has a rotatably connected transmission wheel 34 on the side near the control motor 35. The shaft of the transmission wheel 34 passes through the support plate 33 and is fixedly connected to the axis of the protrusion 38.
[0022] The dust collection mechanism 4 is installed above the hopper 2. The dust collection mechanism 4 includes a protective cover 43, which is located above the hopper 2. Guide grooves 41 are opened on both sides of the hopper 2. Limiting strips 42 are fixedly connected to both sides of the protective cover 43. The limiting strips 42 slide into the guide grooves 41. Two symmetrically arranged diversion hoods 44 are installed on the upper surface of the protective cover 43. The diversion hoods 44 are connected to the hopper 2. The protective cover 43 is quickly fastened to the guide grooves 41 by the limiting strips 42. The dust collection tray 310 can be positioned by inserting the installation strip 39. With the mechanical locking mechanism of the clamping rod 315 and the stop rod 313, the components can be assembled and fixed without special tools. During the dust removal process, the control motor 35 automatically realizes intermittent reciprocating vibration without continuous manual intervention. It is only necessary to start the equipment and monitor the status.
[0023] The upper surface of the diversion hood 44 is equipped with a conduit 45. The end of the conduit 45 away from the diversion hood 44 is fixedly connected to a connector 46. After dust removal, only the baffle 313 needs to be unlocked to remove the dust collection tray 310 and the protective cover 43. The heavy dust can be poured out directly and the parts can be rinsed. There are no complicated dead corners inside the hopper 2. The initial cleaning can be completed after the tea cake is taken out. The parts are made of food-grade durable materials, which are wear-resistant and easy to clean, reducing the frequency of maintenance and replacement costs, and meeting the hygiene and operation and maintenance requirements of food processing equipment.
[0024] The material hopper 2 is rotatably connected to a stop bar 313 on one side. Counterweights 316 are fixedly connected to both sides of one end of the stop bar 313. The dust collection tray 310 and the protective cover 43 are fixedly connected to a stop block 312 on the side near the stop bar 313. When the stop bar 313 is in a vertical state, its two ends abut against the two stop blocks 312 respectively. The center of the arc-shaped limit rod 32 and the center of the limit sleeve 31 coincides with the rotation axis of the protrusion 38, so that the swing trajectory of the material hopper 2 is accurate and without deviation. The elastic reset mechanism of the spring 311 avoids mechanical hard impact and extends the service life of the components. The stop bar 313 automatically returns to the center and locks through the counterweights 316. With the double fixation of the locking rod 315, the protective cover 43 and the dust collection tray 310 are prevented from loosening during the dust removal process.
[0025] Among them, the hopper 2 has a sliding groove 317 on the side near the stop bar 313, and a locking rod 315 is slidably connected in the sliding groove 317. The surface of the stop bar 313 has a locking groove 314, and the locking rod 315 is adapted to the locking groove 314.
[0026] The working principle of this utility model is as follows: First, jasmine tea cakes to be dusted are added to the hopper 2. Due to their own weight, the tea cakes fall onto the sieve plate 318 at the bottom of the hopper 2. The mesh size of the sieve plate 318 only allows dust to pass through, thus stably blocking the tea cakes. Then, the clamping rod 315 on the side of the hopper 2 is pulled to one side. The clamping rod 315 slides along the slide groove 317 and presses against the stop rod 313, causing the stop rod 313 to rotate around the side wall of the hopper 2. When the clamping rod 315 moves to be aligned with the groove 314 on the surface of the stop rod 313, the clamping rod 315 is released. The clamping rod 315 then acts as a limit in the slide groove 317. The lower clip is inserted into the slot 314 to temporarily fix the stop bar 313, preventing interference from the stop bar 313 during component assembly. Then, the limiting strips 42 on both sides of the protective cover 43 are aligned with the guide groove 41 of the hopper 2, and the protective cover 43 is slid down along the guide groove 41 to complete the snap-fit installation. The protective cover 43 covers the upper part of the hopper 2 to form a closed space to prevent light dust from overflowing during dust removal. At the same time, the dust collection tray 310 is inserted into the mounting strip 39 on the lower surface of the hopper 2, so that the dust collection tray 310 is precisely aligned with the bottom of the screen plate 318, ensuring that the dust passing through the screen plate 318 can fall directly into the tray. Component locking and vacuum connection: After installation, push the lever 315 in the original direction to disengage it from the slot 314, press down the stop lever 313 and pull the lever 315 back to its original position, then release the stop lever 313. Under the gravity of the counterweights 316 at both ends, the stop lever 313 automatically returns to a vertical position. Its two ends abut against the stop blocks 312 of the protective cover 43 and the dust collection tray 310 respectively, restricting their displacement and achieving a stable lock. Finally, connect the pipe of the external vacuum cleaner to the conduit 45 above the protective cover 43 through the connector 46 to complete the construction of the vacuum passage. The drive end of the control motor 35 drives the drive wheel 37 to rotate, and the drive wheel 37 drives the transmission wheel 34 to rotate. The shaft of the transmission wheel 34 passes through the support plate 33 and is fixedly connected to the axis of the protrusion 38 of the hopper 2. This causes the hopper 2 to rotate and swing around the rotation connection point between the protrusion 38 and the support plate 33. When the hopper 2 swings, the arc-shaped limiting rod 32 on one side slides synchronously along the inner wall of the arc-shaped limiting sleeve 31 on the bottom plate 1. The center of the limiting sleeve 31 and the limiting rod 32 are both coincident with the rotation axis of the protrusion 38, ensuring a stable sliding trajectory. As the limiting rod 32 slides, the spring 311 on the inner wall of the limiting sleeve 31 is gradually stretched or compressed, generating elastic potential energy, which provides power for the hopper 2 to reset. The control motor 35 adopts an intermittent operation mode. After the material bin 2 swings to the preset amplitude, it stops running. At this time, the spring 311 releases elastic potential energy, which drives the limit rod 32 to slide in the opposite direction, so that the material bin 2 can be quickly reset. After the reset is completed, the motor starts again and drives the material bin 2 to swing to the other side, forming a reciprocating shaking effect. During the shaking process, the tea cakes are constantly turned and collided in the material bin 2, and the dust attached to their surface is shaken off. The larger dust particles are directly passed through the sieve plate 318 and fall into the dust collection tray 310 under the action of gravity. While the hopper 2 is shaking back and forth, the external dust collection equipment is activated to form a negative pressure adsorption channel to clean up the light dust. The light dust that is shaken off in the hopper 2 is suspended in the internal space of the hopper 2 under the action of shaking. The closed environment formed by the protective cover 43 prevents this light dust from overflowing. The suspended light dust is quickly sucked into the diversion hood 44 and transported to the external dust collection equipment through the conduit 45 for collection. The symmetrical design of the diversion hood 44 ensures that the negative pressure distribution in the hopper 2 is uniform, avoids the occurrence of dust collection dead corners, and achieves thorough cleaning of light dust. After the dust removal operation is completed, first turn off the control motor 35 and the external vacuuming equipment, pull the lever 315 to one side to disengage it from the slot 314 of the stop lever 313, press down the stop lever 313 to release the lock on the protective cover 43 and the dust collection tray 310, then remove the protective cover 43 and the dust collection tray 310 in sequence, empty and clean the heavy dust collected in the dust collection tray 310, and then take the tea cake out of the material bin 2 to complete the entire dust removal process. After cleaning, assemble the parts in reverse order, and the equipment returns to its initial state, waiting for the next operation. The entire process combines mechanical shaking with negative pressure adsorption to achieve graded treatment of light and heavy dust, ensuring thorough dust removal while preventing damage to the tea leaves through the 318 sieve plate barrier and gentle shaking, perfectly meeting the cleaning needs of jasmine tea leaves.
[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
