Description

Technical Field

[0001] This invention relates to the field of pest and disease control technology, specifically to a pest and disease control device for forestry seedling cultivation. Background Technology

[0002] Forestry seedling cultivation refers to the cultivation of forest tree seeds or asexual propagation materials in a suitable environment using scientific methods, so that they can develop into robust and high-quality seedlings. This helps to protect and utilize germplasm resources, enrich the structure of forest tree species, and maintain the biodiversity of forest ecosystems. Various diseases and pests often occur during the seedling cultivation process, which require prevention and control.

[0003] In forestry seedling production, chemical control measures are usually required to ensure the healthy growth of seedlings and effectively control diseases and pests. This involves spraying pesticides to inhibit the spread of pathogenic microorganisms and kill harmful insects. Currently, powder (wettable powder) formulations still account for a large proportion of commonly used pesticides. These pesticides must be thoroughly mixed with water to form a uniform suspension before application. However, in practice, most operators simply add the powder directly to the water and perform simple manual or mechanical stirring. Due to insufficient surface tension and wettability of the powder particles, coupled with the rough stirring method, the powder easily agglomerates, forming clumps of varying sizes or "fish-eye" shaped particles. This uneven mixing system not only significantly reduces the effective concentration distribution of the pesticide solution but also clogs the nozzle during spraying and results in insufficient deposition of the actual effective ingredient per unit area, thus severely weakening the field control effect and failing to achieve the expected pest and disease control goals. Summary of the Invention

[0004] The purpose of this invention is to provide a pest and disease control device for forestry seedling cultivation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pest and disease control device for forestry seedling cultivation, comprising: a tank, wherein a spraying device is provided inside and on top of the tank, and the spraying device is used to draw a mixed liquid inside the tank for spraying; A pesticide storage tank, located on top of the main body, is used to store pesticide powder; The water inlet pipe is located at the top of the tank and is used to connect an external water pipe to supply water to the tank. A mixing device, located inside the tank, is used to thoroughly mix water and pesticide powder; The mixing device includes: a receiving plate, a connecting column fixed at the center of the receiving plate, and the top of the connecting column fixed to the inner wall of the tank; The water inlet is located at the top of the receiving plate. The receiving plate has a guide hole inside, which is connected to the water inlet and extends to the inside of the receiving plate.

[0006] According to the above technical solution, a collar is rotatably installed on the outer wall of the connecting column, and four sets of vertical plates are fixed on the outer wall of the collar. A through drain hole is opened at the bottom of the receiving plate near the connecting column.

[0007] According to the above technical solution, the water inlet pipe passes through the top of the tank and is fixedly connected to the tank. The bottom of the water inlet pipe is fixed to the top of the receiving plate, and the water inlet pipe is connected to the water inlet.

[0008] According to the above technical solution, the spraying device includes a water pump, which is installed at the top of the tank. The suction end of the water pump is provided with a suction pipe that extends into the interior of the tank. The discharge end of the water pump is provided with a spray pipe, and the bottom of the spray pipe is provided with a nozzle.

[0009] According to the above technical solution, the bottom of the storage tank and the inner side of the receiving plate are provided with an intermittent feeding structure, which is used to control the intermittent feeding of pesticide powder in the storage tank; The bottom of the storage tank and the top of the collar are equipped with auxiliary devices, which are used to assist in the feeding of pesticide powder.

[0010] According to the above technical solution, the intermittent feeding structure includes: a feeding pipe, which is fixed to the bottom of the medicine storage tank and is connected to the medicine storage tank; A baffle, which is hinged to a bracket, and the bracket is fixed to the outer wall of the feed pipe; A support spring, one end of which is fixed to the top of the baffle, and the other end of which is fixed to the outer wall of the feed tube; A sliding block is slidably installed on the inner side of the receiving plate. A top rod is fixed to the top of the sliding block, and the top of the top rod is in contact with the bottom of the baffle. An inclined surface is provided on the bottom side of the sliding block near the center of the receiving plate.

[0011] According to the above technical solution, a rubber column is fixed on the inner side of the receiving plate.

[0012] According to the above technical solution, the inner wall of the medicine storage tank is conical, and the top of the medicine storage tank is threadedly connected to a tank lid.

[0013] According to the above technical solution, the auxiliary device includes: five sets of abutting posts, which are fixed in a circumferential array on the top of the collar; A support rod, the top of which is fixed to the inner wall of the tank, the support rod passing through the top of the beater plate and being rotatably connected to the beater plate; A spiral spring, one end of which is fixed to the outer wall of the support rod, and the other end of which is fixed to the inner wall of the striking plate.

[0014] Compared with the prior art, the present invention provides a pest and disease control device for forestry seedling cultivation, which has the following beneficial effects: 1. This invention utilizes a mixing device. External water flows into the inlet through the inlet pipe and, guided by the guide holes, enters the receiving tray at an angle. The rapidly flowing water rotates within the receiving tray due to its own impact as it enters through the guide holes. When pesticide powder from the storage tank falls into the receiving tray, the water flow carries the pesticide powder, achieving rapid mixing without manual operation. This prevents the pesticide powder from agglomerating and forming clumps or particles, which would affect the concentration distribution of the pesticide solution. As the water flows and rotates within the receiving tray, the rapid flow impacts the vertical plate, causing it to rotate synchronously. The vertical plate further impacts the pesticide powder mixed in the water flow, aiding in mixing. The mixed pesticide solution then passes through the drain hole, through the receiving tray, and falls into the tank, where it is extracted by the spraying device for spraying to control pests and diseases.

[0015] 2. This invention, through its mixing device and intermittent feeding structure, allows pesticide powder from the storage tank to enter the feeding pipe. When water flows into the receiving tray and impacts the vertical plate, the vertical plate rotates. When the vertical plate rotates to the position of the sliding block, it abuts against the inclined surface at the bottom of the sliding block, pushing the sliding block upward a certain distance. The sliding block then moves upward synchronously with the push rod, which abuts against the bottom of the baffle, causing the baffle to swing at a hinged position with the support. This prevents the baffle from blocking the bottom of the feeding pipe, allowing the pesticide powder in the feeding pipe to fall into the receiving tray. When the vertical plate no longer abuts the sliding block, the sliding block returns to its original position under its own weight and the pushing action of the baffle. The baffle, under the action of the supporting spring, returns to its original position and blocks the feeding pipe again. By rotating the vertical plate, the intermittent opening and closing of the baffle is controlled, thus controlling the intermittent feeding of pesticide powder and avoiding excessive feeding at one time, which would cause the pesticide powder to clump and affect the mixing effect.

[0016] 3. This invention, through the auxiliary device, allows the collar to rotate synchronously with the abutment post when the collar rotates. When the abutment post abuts against the striking plate, it can push the striking plate to rotate. When the abutment post moves to a position where it no longer abuts against the striking plate, the striking plate can rotate and reset under the action of the spiral spring. The striking plate strikes the outer wall of the feeding pipe, assisting the feeding pipe in the feeding operation and preventing pesticide powder from accumulating in the feeding pipe and causing blockage, thus affecting normal feeding.

Detailed Implementation

[0019] Please see Figures 1-10 One embodiment of the present invention is: a pest and disease control device for forestry seedling cultivation, comprising: a tank 1, a spraying device 5 provided inside and on top of the tank 1, the spraying device 5 being used to draw mixed liquid inside the tank 1 for spraying, a pesticide storage tank 6 being provided above the tank 1 for storing pesticide powder, a water inlet pipe 7 being provided above the tank 1 for connecting an external water pipe to supply water to the tank 1, and a mixing device 2 being provided inside the tank 1 for fully mixing water and pesticide powder; The mixing device 2 includes: a receiving plate 21, a connecting column 22, a water inlet 23, a guide hole 24, a collar 25, a vertical plate 26, and a drain hole 27; A connecting column 22 is fixed at the center of the receiving plate 21. The top of the connecting column 22 is fixed to the inner wall of the tank 1 and is located at the top of the receiving plate 21. A guide hole 24 is provided inside the receiving plate 21. The guide hole 24 is connected to the water inlet 23 and extends to the inner side of the receiving plate 21. External water flows into the water inlet 23 through the water inlet pipe 7 and can enter the receiving plate 21 obliquely under the guidance of the guide hole 24. When the fast-flowing water enters the receiving plate 21 through the guide hole 24, it can rotate in the receiving plate 21 under its own impact. When the pesticide powder in the storage tank 6 falls into the receiving plate 21, the water can carry the pesticide powder to rotate, realizing rapid mixing. There is no need for manual mixing by the staff, which avoids the pesticide powder from agglomerating and forming lumps or particles, affecting the concentration distribution of the pesticide solution.

[0020] A collar 25 is rotatably installed on the outer wall of the connecting column 22. Four sets of vertical plates 26 are fixed on the outer wall of the collar 25. A through drain hole 27 is opened at the bottom of the receiving plate 21 near the connecting column 22. When the water flows into the receiving plate 21 and rotates, the fast-flowing water impacts the vertical plates 26, pushing the vertical plates 26 to rotate synchronously. The vertical plates 26 can impact the pesticide powder mixed in the water flow, assisting in its mixing. The mixed pesticide solution can pass through the drain hole 27 through the receiving plate 21 and fall into the tank 1. It is then extracted by the spraying device 5 for spraying to control pests and diseases.

[0021] The water inlet pipe 7 passes through the top of the tank body 1 and is fixedly connected to the tank body 1. The bottom of the water inlet pipe 7 is fixed to the top of the receiving plate 21, and the water inlet pipe 7 is connected to the water inlet 23. After the water inlet pipe 7 is connected to the external water pipe, the water flow can enter the water inlet 23 through the water inlet pipe 7. The flow rate of the water is accelerated through the narrowed guide hole 24, so that the water flow can quickly enter the receiving plate 21 and enhance the swirling mixing effect.

[0022] The spraying device 5 includes a water pump 51, which is installed on the top of the tank 1. The suction end of the water pump 51 is provided with a suction pipe 52, which extends into the interior of the tank 1. The discharge end of the water pump 51 is provided with a spray pipe 53, and the bottom of the spray pipe 53 is provided with a nozzle. The water pump 51 draws the pesticide solution from inside the tank 1 through the suction pipe 52, and then sprays it out through the nozzle on the spray pipe 53 to spray the pesticide solution, thereby achieving pest and disease control.

[0023] In this embodiment, the tank 1 is placed in the forestry seedling location, the inlet pipe 7 is connected to the external water pipe, the water pump 51 is connected to an external power source, and the external water pipe supplies water to the receiving plate 21 through the inlet pipe 7. The external water flow enters the inlet 23 through the inlet pipe 7, and then enters the receiving plate 21 at an angle under the guidance of the guide hole 24. When the rapidly flowing water enters the receiving plate 21 through the guide hole 24, it rotates in the receiving plate 21 under its own impact. When the water flows into the receiving plate 21 and rotates, the rapidly flowing water impacts the vertical plate 26, pushing the vertical plate 26 to rotate synchronously. The vertical plate 26 can impact the pesticide powder mixed in the water flow, assisting in its mixing. The mixed pesticide solution can pass through the drain hole 27 through the receiving plate 21 and fall into the interior of the tank 1.

[0024] Then start the water pump 51. The water pump 51 draws the liquid medicine inside the tank 1 through the suction pipe 52, and then sprays it out through the nozzle on the spray pipe 53 to achieve pest and disease control.

[0025] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, an intermittent feeding structure 3 is provided at the bottom of the storage tank 6 and on the inner side of the receiving plate 21. The intermittent feeding structure 3 is used to control the intermittent feeding of pesticide powder in the storage tank 6. The bottom of the storage tank 6 and the top of the collar 25 are equipped with auxiliary devices 4. The auxiliary devices 4 are used to assist the feeding of pesticide powder. The intermittent feeding structure 3 can prevent a large amount of pesticide powder from being added into the tank 1 at one time, which would prevent the pesticide powder from being fully dissolved in water. The auxiliary devices 4 can also prevent the pesticide powder from accumulating and clogging, which would affect the normal feeding.

[0026] The intermittent feeding structure 3 includes: feeding pipe 31, baffle 32, bracket 33, support spring 34, sliding block 35, and push rod 36; The discharge pipe 31 is fixed to the bottom of the storage tank 6 and is connected to the storage tank 6. The baffle 32 is hinged to the bracket 33, which is fixed to the outer wall of the discharge pipe 31. One end of the support spring 34 is fixed to the top of the baffle 32, and the other end is fixed to the outer wall of the discharge pipe 31. The sliding block 35 is slidably installed on the inner side of the receiving plate 21. A top rod 36 is fixed to the top of the sliding block 35, and the top of the top rod 36 is in contact with the bottom of the baffle 32. An inclined surface is provided on the bottom side of the sliding block 35 near the center of the receiving plate 21. The pesticide powder in the storage tank 6 enters the discharge pipe 31. When the water flows into the receiving plate 21 and impacts the vertical plate 26, the vertical plate 26 rotates. When the vertical plate 26 rotates to the position of the sliding block 35, it abuts against the bottom of the sliding block 35. On the inclined surface, pushing the sliding block 35 upward a certain distance causes the sliding block 35 to move upward synchronously with the push rod 36. The push rod 36 abuts against the bottom of the baffle 32, causing the baffle 32 to swing at the hinged position with the bracket 33. This prevents the baffle 32 from blocking the bottom of the discharge pipe 31, allowing the pesticide powder in the discharge pipe 31 to fall into the receiving tray 21. When the vertical plate 26 no longer abuts against the sliding block 35, the sliding block 35 resets downward under its own weight and the pushing action of the baffle 32. The baffle 32 resets under the action of the supporting spring 34 and blocks the discharge pipe 31 again. By rotating the vertical plate 26, the intermittent opening and closing of the baffle 32 can be controlled, thus controlling the intermittent discharge of pesticide powder and avoiding excessive feeding at one time, which would cause the pesticide powder to clump and affect the mixing effect.

[0027] A rubber column 8 is fixed to the inside of the receiving plate 21. The rubber column 8 can come into contact with the vertical plate 26. When the water flow impacts the vertical plate 26 and it rotates, the vertical plate 26 receives enough thrust to overcome the resistance generated by the friction of the rubber column 8, and will not affect the normal rotation of the vertical plate 26. When the water flow stops entering the receiving plate 21, the vertical plate 26 no longer receives enough thrust, and the vertical plate 26 gradually stops rotating under the action of centrifugal force. When the vertical plate 26 touches the rubber column 8, it can stop rotating under the action of frictional resistance, thereby preventing the vertical plate 26 from staying at the position of the sliding block 35, which would affect the normal downward reset of the sliding block 35 and cause the baffle 32 to fail to close.

[0028] The inner wall of the storage tank 6 is conical, and the top of the storage tank 6 is threadedly connected to the tank cover 61. Through the conical interior of the storage tank 6, the pesticide powder in the storage tank 6 can smoothly enter the feed pipe 31. And through the threaded tank cover 61, the pesticide powder in the storage tank 6 can be replenished by opening the tank cover 61.

[0029] Auxiliary device 4 includes: five sets of contact columns 41, support rods 42, striking plates 43, and spiral springs 44; Five sets of contact posts 41 are fixed in a circular array on the top of the collar 25. The top of the support rod 42 is fixed on the inner wall of the tank 1. The support rod 42 passes through the top of the striking plate 43 and is rotatably connected to the striking plate 43. One end of the spiral spring 44 is fixed to the outer wall of the support rod 42, and the other end of the spiral spring 44 is fixed to the inner wall of the striking plate 43. When the collar 25 rotates, the collar 25 rotates synchronously with the contact posts 41. When the contact posts 41 abut against the striking plate 43, they can push the striking plate 43 to rotate. When the contact posts 41 move to a position where they no longer abut against the striking plate 43, the striking plate 43 can rotate and reset under the action of the spiral spring 44. The striking plate 43 strikes the outer wall of the discharge pipe 31 to assist the discharge pipe 31 in the discharge operation and prevent pesticide powder from accumulating in the discharge pipe 31 and causing blockage, which would affect normal discharge.

[0030] In this embodiment, during operation: the pesticide powder in the storage tank 6 enters the feed pipe 31. When the water flows into the receiving plate 21 and impacts the vertical plate 26, the vertical plate 26 rotates. When the vertical plate 26 rotates to the position of the sliding block 35, it abuts against the inclined surface at the bottom of the sliding block 35, pushing the sliding block 35 upward a certain distance. The sliding block 35 then moves upward synchronously with the push rod 36. The push rod 36 abuts against the bottom of the baffle 32, causing the baffle 32 to swing at the hinged position with the bracket 33. This prevents the baffle 32 from blocking the bottom of the discharge pipe 31, allowing the pesticide powder inside the discharge pipe 31 to fall into the receiving tray 21. When the vertical plate 26 no longer contacts the sliding block 35, the sliding block 35 resets downwards under its own weight and the pushing action of the baffle 32. The baffle 32 resets under the action of the supporting spring 34 and blocks the discharge pipe 31 again. By rotating the vertical plate 26, the intermittent opening and closing of the baffle 32 can be controlled, thus controlling the intermittent discharge of pesticide powder.

[0031] When the collar 25 rotates, the collar 25 rotates synchronously with the abutting post 41. When the abutting post 41 abuts against the striking plate 43, it can push the striking plate 43 to rotate. When the abutting post 41 moves to no longer abut against the striking plate 43, the striking plate 43 can rotate and reset under the action of the spiral spring 44. The striking plate 43 strikes the outer wall of the feeding pipe 31 to assist the feeding pipe 31 in the feeding operation and avoid pesticide powder from accumulating in the feeding pipe 31 and causing blockage.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
