Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1-6 As shown, this embodiment provides an example of a movable multi-hole spraying device for rehumidifying flue-cured tobacco. In this embodiment, the hoisting device includes a movable multi-hole spraying device for rehumidifying flue-cured tobacco. The hoisting device includes: a hanging rod 1, which is divided into a suspension part and a hand-held part. The suspension part of the hanging rod 1 has placement cavities 2 on both sides. The hand-held part of the hanging rod 1 has a handle 103, and the top of the suspension part of the hanging rod 1 has a hook 101; a pump 3, which has an inlet pipe 301 at the top and a pump pipe 303 connected to the bottom of the pump 3 and the inside of the hanging rod 1; a spraying component, which is located inside the placement cavity 2 and is used to connect the pump pipe 303 to spray liquid on both sides for rehumidification; and a driving component, which is located inside the placement cavity 2 and is used to drive the spraying component to move back and forth and spray the tobacco leaves on one side to cool them down.

[0022] The bottom of the hook 101 is provided with multiple anti-slip strips 102, which are evenly distributed and made of rubber.

[0023] During use, the operator holds the handle 103 of the hanging rod 1 and moves the device to the tobacco curing hanging area. The hanging rod 1 is then suspended on the crossbeam of the tobacco curing rack via the hook 101 at the top of the hanging part. Multiple rubber anti-slip strips 102 at the bottom of the hook 101 contact the crossbeam and are in close contact with the surface of the crossbeam. The rubber material maintains elasticity in high humidity environments, increasing static friction. At the same time, the anti-slip strips 102 prevent the device from accidentally slipping due to vibration or liquid spraying. After hanging, the tobacco leaves on both sides are moistened by the sprayer. The drive unit can move the sprayer up and down or adjust the height to spray tobacco leaves at different heights, thus providing targeted moisturization of the tobacco leaves.

[0024] The spraying component includes: a spray plate 201 disposed inside the placement cavity 2, with multiple spray nozzles 202 on one side of the spray plate 201; and a spray pipe 104 disposed at the bottom of the spray plate 201 and connected to the pump pipe 303, with the top of the spray pipe 104 entering the interior of the spray plate 201 and being interconnected with the multiple spray nozzles 202.

[0025] Among them, the multiple spray nozzles 202 are divided into two groups: upper spray nozzles and lower spray nozzles, and the two groups of spray nozzles 202 are staggered at equal intervals.

[0026] During use, the liquid is delivered to the internal cavity of the spray plate 201 through the spray pipe 104. The liquid is sprayed out through two sets of spray nozzles 202, with the upper nozzle tilting upward and the lower nozzle tilting downward, forming a cross spray covering the front and back of the tobacco leaves. The staggered design of the upper and lower nozzles ensures that the tobacco leaves are evenly moistened on both sides, avoiding local over-dampness or dryness.

[0027] The spray nozzle 202 has a mesh plate 203 inside. The mesh plate 203 has multiple openings on its surface, and these openings are cone-shaped sharp openings. When the liquid flows through the cone-shaped sharp openings of the mesh plate 203, it is divided into small droplets due to the shrinkage of the cross section. The cone-shaped openings enhance the liquid flow rate and atomization effect, forming a uniform water mist and reducing the impact damage to the tobacco leaf surface.

[0028] The pump 3 is equipped with a control panel 302 on one side. The control panel 302 is electrically connected to the pump 3 and the drive motor 207. During use, the spraying time, pump flow rate and drive motor speed are set through the control panel 302. The control panel 302 sends instructions to the pump 3 and drive motor 207 to start synchronous operation. Based on the feedback of tobacco leaf humidity, the parameters are manually adjusted to optimize the spraying effect.

[0029] The driving components include: two drive motors 207 located inside the suspension part of the hanging rod 1, with the two drive motors 207 respectively located at the bottom of the two placement cavities 2, and a threaded rod 208 connected to the top of the drive motors 207. The threaded rod 208 passes through the placement cavity 2, and the part of the threaded rod 208 that contacts the hanging rod 1 is connected by a ball bearing; and a threaded opening is opened on the spray plate 201, and the spray plate 201 is threadedly engaged with the threaded rod 208 through the threaded opening.

[0030] During use, after the drive motor 207 is powered on, it drives the threaded rod 208 to rotate clockwise / counterclockwise. The spray plate 201 engages with the threaded rod 208 through the threaded opening and moves up and down in the vertical direction as the threaded rod rotates. Through dynamic spraying, it covers different height areas of the tobacco leaves and avoids fixed spray dead angles.

[0031] The placement cavity 2 has limit grooves 205 on both sides, and a limit rod 206 is provided inside the limit groove 205. The spray plate 201 has limit blocks 204 on both sides, and the limit blocks 204 and the limit rods 206 are slidably connected to each other. The limit blocks 204 on both sides of the spray plate 201 are embedded in the limit grooves 205 of the placement cavity 2 and slide along the limit rods 206. The limit rods 206 restrict the spray plate 201 to move only in the vertical direction, so as to avoid deflection or jamming.

[0032] It should be noted that the threaded rod 208, the thread, the drive motor 207 and the pump 3 are all conventional applications of the prior art, and their detailed structures will not be described in detail in this embodiment, nor will they be shown in the accompanying drawings.

[0033] When using this device for rehumidification, the operator first moves the device to the tobacco curing area using the handle 103 on the hanging rod 1. The device is then suspended from the crossbeam of the tobacco curing rack using the hook 101 at the top of the hanging part. The rubber anti-slip strip 102 at the bottom of the hook 101 is in close contact with the crossbeam to prevent slippage. After startup, the pump 3 draws in the rehumidification liquid through the inlet pipe 301, and delivers the liquid through the built-in pump pipe 303 to the spray pipe 104 inside the hanging rod 1, injecting it into the spray plates 201 in the side placement chambers 2. After entering the spray plates 201, the liquid is sprayed out through two sets of staggered upper and lower nozzles 202. The conical, sharp-opening mesh plate 203 inside the spray nozzles 202 divides the liquid into uniform droplets, covering both sides of the tobacco leaves.

[0034] Simultaneously, the drive motor 207 drives the threaded rod 208 to rotate, and the spray plate 201 engages with the threaded rod 208 through the bottom threaded opening, moving up and down reciprocally in the vertical direction; the limiting blocks 204 on both sides of the spray plate 201 are embedded in the limiting grooves 205 of the placement cavity 2 and slide along the limiting rod 206 to ensure stable movement trajectory. The operator adjusts the flow rate of the pump 3 and the speed of the drive motor 207 in real time through the control panel 302 to control the spray intensity and the moving speed of the spray plate 201, so that the water mist dynamically covers different height areas of the tobacco leaves until the tobacco leaves are evenly moistened.

[0035] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
