Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum. Background Technology

[0002] As a Chinese medicinal herb with significant economic value, pest and disease control during its cultivation is crucial for ensuring yield and quality. Currently, spraying devices are the primary equipment for pesticide application, effectively controlling pests and diseases by atomizing and spraying the pesticide solution.

[0003] In the practice of pest and disease control for Cynanchum paniculatum, it is often necessary to use solid pesticides such as wettable powders. These pesticides need to be mixed with water to form a suspension when used, but their inherent physical properties make it difficult for the powder particles to be completely and uniformly suspended in water, especially when the solution is left to stand or not stirred sufficiently, which can easily lead to precipitation or the formation of large particle clusters.

[0004] Existing spraying equipment typically includes simple filters at the outlet of the pesticide tank to prevent undissolved pesticide particles from entering the delivery pipes and nozzles. However, this passive filtration method has significant shortcomings. Under the pressure pulsations and machine vibrations generated by the spraying pump, these simply installed filters are prone to displacement or deformation, creating gaps at their edges. This allows large pesticide particles to bypass the filter and directly enter the pipes, ultimately clogging the nozzles. Once the nozzles are clogged, spraying operations are not only interrupted, affecting pest control efficiency, but the sudden pressure changes can also damage the equipment.

[0005] Therefore, how to design a spraying device that can ensure thorough mixing of the pesticide solution and reliably fix the filter screen, thereby eliminating the problem of nozzle clogging caused by pesticide powder particles from the source, is a technical problem that urgently needs to be solved in the current field of Baiwei cultivation.

[0006] Therefore, this utility model proposes a spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum to address the shortcomings of the existing technology. Utility Model Content

[0007] In the existing technology, the filter screen of the spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum is simply clipped or fixed, which is prone to displacement under the pressure of the liquid and vibration, resulting in filter gaps. This causes undissolved powder particles to enter the pipe and clog the nozzle, affecting the continuity and reliability of the operation. The present invention aims to provide a spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum, including a base, a pesticide tank fixedly connected to the top of the base, a filter screen detachably installed inside the pesticide tank, and a delivery pipe connected to the pesticide tank; the device also includes an anti-clogging mechanism installed inside the pesticide tank.

[0009] The anti-clogging mechanism includes a motor installed inside the medicine tank, a stirring paddle driven by a drive source inside the device, and an actuation component.

[0010] The motor has a drive wheel fixedly connected to its output end, and a driven wheel is rotatably connected to the actuator. The drive wheel is connected to the driven wheel via a belt.

[0011] The driven wheel is coaxially and fixedly connected to a lead screw.

[0012] The execution component also includes a slide rail fixed inside the medicine tank, a clamping block one slidably connected to the slide rail, and a clamping block two fixedly disposed thereon.

[0013] The clamping block one is threadedly connected to the lead screw, and when the lead screw is driven to rotate by the motor drive transmission chain, the clamping block one can move along the slide rail and cooperate with the clamping block two to clamp and fix the filter screen.

[0014] Preferably, in order to achieve a more stable installation and clamping, a connecting block is fixedly connected to the filter screen, and the first clamping block and the second clamping block clamp the connecting block to lock the filter screen; a locking block is also fixedly connected to the filter screen, and the locking block is used to engage with the corresponding groove inside the medicine tank so as to conveniently perform preliminary positioning of the filter screen before automatic clamping.

[0015] Preferably, to improve the applicability of the device to cope with different pest and disease scenarios, the device further includes a replacement mechanism disposed at the end of the delivery pipe. The replacement mechanism includes a fixing block fixed to the delivery pipe, a rotating ring rotatably sleeved on the fixing block, and a clamping assembly linked to the rotating ring, the clamping assembly being used to clamp or release the nozzle.

[0016] Preferably, as a linkage implementation method for the replacement mechanism, the clamping assembly includes a linkage ring. The rotating ring is connected to the linkage ring via a connecting column. An arc-shaped groove is formed on the fixing block, which guides and restricts the movement trajectory of the connecting column to ensure smooth linkage.

[0017] Preferably, to convert rotational motion into clamping motion, a sliding column is fixedly connected to the linkage ring, and a rotating rod is rotatably connected to the fixed block. One end of the sliding column is slidably accommodated in a groove on the rotating rod. When the linkage ring moves, it drives the rotating rod to rotate around its axis via the sliding column, thereby achieving the clamping action.

[0018] Preferably, in order to lock and unlock the replacement action, the clamping assembly further includes a retaining ring for locking the rotating ring, and a spring for providing an automatic reset force to the retaining ring.

[0019] Preferably, as a specific assembly structure of the locking mechanism, the clamping assembly further includes a retaining ring sleeved on the delivery pipe. The spring is sleeved on the rod portion of the retaining ring, and both ends of the spring are respectively fixed between the retaining ring and the retaining ring, forming a stable elastic force application structure.

[0020] Preferably, to enhance the mixing effect of the drug solution, the blades of the stirring paddle are plate-shaped. Furthermore, the rotating shaft of the stirring paddle is coaxially and fixedly connected to the output shaft of the device's drive source. This structure can generate a more complex flow field during stirring, promoting rapid dissolution and suspension of the drug powder.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model solves the problem in the prior art of affecting the continuity of operation due to uneven dissolution of medicine powder and large particulate impurities causing nozzle blockage by setting an anti-clogging mechanism that integrates a stirring paddle and a motor-driven automatic clamping execution component.

Detailed Implementation

[0031] Example:

[0032] Reference Figures 1 to 5 This utility model provides a spraying device for the prevention and control of diseases and pests in the cultivation of Cynanchum paniculatum, which aims to solve the problems in the prior art that cause nozzle clogging due to uneven dissolution of pesticide powder and the inability to quickly replace nozzles according to different disease and pest scenarios.

[0033] like Figure 1 and Figure 2 As shown, the spraying device for pest and disease control in Baiwei planting includes a base 1, a pesticide tank 2 fixedly connected to the top of the base 1, and a delivery pipe 5 connected to the pesticide tank 2; the device also includes an anti-clogging mechanism 3 installed inside the pesticide tank 2 and a replacement mechanism 6 installed at the end of the delivery pipe 5; the anti-clogging mechanism 3 is used to stir and mix the pesticide solution and automatically lock the filter screen 4, and the replacement mechanism 6 is used to realize the quick clamping and replacement of different functional nozzles; see reference. Figure 2The anti-clogging mechanism 3 includes a motor 31 installed inside the medicine tank 2. A stirring paddle 37 is coaxially and fixedly connected to the output shaft of the drive source within the device. The blades of the stirring paddle 37 are spiral-shaped, used to generate a rotating water flow within the medicine tank 2 to fully mix the medicine powder and water. The anti-clogging mechanism 3 also includes an actuation component 36, which automatically clamps the filter screen 4 detachably installed inside the medicine tank 2. Specifically, a drive wheel 32 is fixedly connected to the output end of the motor 31, and a driven wheel 34 is rotatably connected to the actuation component 36. The drive wheel 32 is connected to the driven wheel 34 via a belt 33. The transmission connection includes a driven wheel 34 coaxially fixedly connected to a lead screw 35; the actuation assembly 36 also includes a slide rail 361 fixed inside the medicine tank 2, a clamping block 362 slidably connected to the slide rail 361 and threadedly connected to the lead screw 35, and a clamping block 363 fixedly installed; when the motor 31 works, it drives the lead screw 35 to rotate through the drive wheel 32, belt 33 and driven wheel 34, and the threaded clamping block 362 will move linearly along the slide rail 361, thereby cooperating with the clamping block 363 to complete the clamping and fixing action of the filter screen 4; see reference. Figure 3 and Figure 4 A connecting block 364 is fixedly connected to the filter screen 4 for clamping by clamping block 1 362 and clamping block 2 363. A locking block 365 is also fixedly connected to the filter screen 4. The locking block 365 is used to lock into the corresponding groove inside the medicine tank 2, so as to initially position the filter screen 4 during installation.

[0034] Reference Figure 1 and Figure 5 The replacement mechanism 6 is located at the end of the delivery pipe 5, and includes a fixing block 64 fixed to the delivery pipe 5, a rotating ring 61 rotatably sleeved on the fixing block 64, and a clamping assembly 65 linked to the rotating ring 61. The fixing block 64 has an arc-shaped groove 63 for the connecting post 62 to slide when the rotating ring 61 rotates. A rotating rod 653 for directly clamping or releasing the nozzle is also rotatably connected to the fixing block 64. The clamping assembly 65 includes a linkage ring 651, and the rotating ring 61 is connected to the linkage ring 651 through the connecting post 62. A sliding post 652 is fixedly connected to the linkage ring 651, and one end of the sliding post 652 is slidably accommodated. The rotating ring 651 is placed in a groove on the rotating rod 653, so that when the rotating ring 61 drives the linkage ring 651 to move, the rotating rod 653 is driven to rotate through the sliding column 652 to achieve the clamping or releasing action of the nozzle. The clamping assembly 65 also includes a retaining ring 654 for locking the rotating ring 61, a spring 655 for providing a restoring force to the retaining ring 654, and a fixing ring 656 sleeved on the delivery pipe 5. The spring 655 is sleeved on the rod of the retaining ring 654, and the two ends of the spring 655 abut against the fixing ring 656 and the retaining ring 654 respectively. By pulling out or releasing the retaining ring 654, the rotating ring 61 can be unlocked or locked.

[0035] As a preferred embodiment, in order to ensure the installation stability of the filter screen 4 before it is automatically clamped, a connecting block 364 is fixedly connected to the filter screen 4. Clamping block 362 and clamping block 363 clamp the connecting block 364 to achieve the final locking of the filter screen 4. At the same time, a locking block 365 is also fixedly connected to the filter screen 4. The locking block 365 is engaged in the corresponding groove preset inside the medicine tank 2 during installation, thereby forming a stable initial positioning of the filter screen 4.

[0036] As another preferred embodiment, in order to achieve precise linkage between the rotation of the rotating ring 61 and the clamping action of the rotating rod 653, the linkage ring 651 of the clamping assembly 65 is connected to the rotating ring 61 through the connecting post 62, and the arc-shaped groove 63 opened on the fixing block 64 guides and restricts the movement trajectory of the connecting post 62. A sliding post 652 is further fixedly connected to the linkage ring 651, and one end of the sliding post 652 is slidably accommodated in the sliding groove opened on the rotating rod 653, thereby smoothly converting the movement of the linkage ring 651 into the rotation of the rotating rod 653.

[0037] As another preferred embodiment, in order to achieve reliable locking and convenient unlocking of the replacement mechanism 6, the clamping assembly 65 also includes an axially movable retaining ring 654 and a spring 655 that provides a restoring force. The retaining ring 654 is used to selectively engage the rotating ring 61 for circumferential positioning. The spring 655 is sleeved on the rod of the retaining ring 654. The two ends of the spring 655 are respectively fixed to the fixing ring 656 and the retaining ring 654. The fixing ring 656 is sleeved and fixed on the delivery pipe 5. The spring 655 always provides a spring force to reset the retaining ring 654 toward the rotating ring 61.

[0038] As another preferred embodiment, in order to improve the mixing efficiency of the medicine solution, the blades of the stirring paddle 37 are spiral-shaped, and the rotating shaft of the stirring paddle 37 is coaxially and fixedly connected to the output shaft of the drive source in the device. The structure can generate a complex mixing flow field in the medicine tank 2 during stirring, which effectively promotes the suspension and dissolution of the medicine powder particles.

[0039] The working principle is as follows:

[0040] When mixing and fixing the medicine solution, firstly, the filter screen 4 is installed inside the medicine tank 2, and the locking block 365 on it is engaged in the corresponding slot to complete the initial positioning. Then, the motor 31 is started. The motor 31 transmits the rotational motion to the lead screw 35 through the drive wheel 32, belt 33 and driven wheel 34 at its output end. The rotation of the lead screw 35 causes the first clamping block 362 connected to it to move axially along the fixed slide rail 361 until it works with the second clamping block 363 to firmly clamp the connecting block 364 on the filter screen 4, thereby completing the automatic locking of the filter screen 4. This ensures that during the spraying process, larger particles of medicine powder cannot pass through the filter screen 4 and enter the delivery pipe 5. The output shaft of the device drive source coaxially drives the stirring paddle 37 to rotate. The spiral blades of the stirring paddle 37 generate complex vortices in the medicine tank 2, which promotes the full mixing of medicine powder and water.

[0041] When replacing the nozzle, the operator first pulls the retaining ring 654 out along the axial direction of the delivery pipe 5, compressing the spring 655, so that the retaining ring 654 is released from its lock on the rotating ring 61. At this time, the rotating ring 61 becomes free to rotate. The operator rotates the rotating ring 61, and the rotating ring 61 drives the linkage ring 651 to move along the trajectory of the arc groove 63 through the connecting column 62. The movement of the linkage ring 651 drives the rotating rod 653 to rotate around its fulcrum through the sliding column 652 fixed on it, so that the clamping end of the rotating rod 653 opens or closes to release or clamp the nozzle. After the replacement is completed, the retaining ring 654 is released, the elastic potential energy stored in the spring 655 is released, and the retaining ring 654 automatically resets and re-clamps into the rotating ring 61, thus completing the reliable locking of the replaced nozzle.
