[0002] Seedling cultivation is an effective way to cultivate forestry seedlings. After the cultivation of forestry seedlings is completed, the roots of the cultivated seedlings need to be soaked before planting. The purpose of root soaking is very important. It is mainly to disinfect the roots of the seedlings to prevent the roots of the seedlings from being infected by bacteria, thereby achieving the purpose of disease and pest control, and then improving the survival rate of tree seedlings. At present, when the seedlings are root-soaked, the seedlings are collectively placed in a root soaking box, and then lime water and other disinfectants are used to soak the roots of the seedlings. After soaking for a period of time, the disinfectant may produce precipitation and affect the root soaking effect, and then affect the effect of disease and pest control.

[0018] 1. The present invention arranges a fixed plate above the base, and an inclined drainage part, a horizontal filtering part, an inclined transition part, a horizontal immersion part and an inclined sedimentation part above the fixed plate. A plurality of incubation boxes are arranged above the base. The seedling cultivation pots can be placed in the incubation boxes, and the incubation boxes can circulate on the base under the traction of a circulating chain. During the circulation process of the incubation boxes, the inclined drainage part, the horizontal filtering part, the inclined transition part, the horizontal immersion part and the inclined sedimentation part are sequentially passed.

[0019] 2. The present invention arranges a first partition, a second partition and a third partition inside the base. The first partition, the second partition, the third partition and the base define a water replenishment chamber, a filter chamber, a mixing chamber and a medicine circulation chamber. The water replenishment chamber can store medicine for replenishment, the filter chamber can filter the medicine discharged from the incubator, and the mixing chamber can mix the used medicine with the newly replenished medicine. The medicine circulation chamber can realize the circulation of the medicine and complete the automatic replenishment of the medicine, thereby ensuring the efficacy of the medicine while realizing the recycling of the medicine. At the same time, the circulation of the medicine can increase the oxygen content inside it and improve the soaking effect of the seedlings.

[0020] 3. The present invention provides a drainage hole on one side of the incubator. When the incubator is tilted, the medicine inside can be discharged through the drainage hole. When the incubator passes through the horizontal immersion part, the medicine can enter the incubator through the drainage hole to complete replenishment. A baffle is provided inside the incubator to guide the flow direction of the medicine, thereby preventing the medicine from directly passing through the drainage hole to impact the roots of the seedlings and causing damage to the roots of the seedlings, thereby achieving the effect of protecting the roots of the seedlings.

[0021] 4. The present invention arranges the first permanent magnet part and the second permanent magnet part at the bottom of the incubator to prevent the problems of uneven concentration distribution and precipitation in the medicine in the incubator. When in use, the first permanent magnet part and the second permanent magnet part at the bottom of two incubators close to each other attract / repel each other, causing the two incubators to flip and generate a small shake, so that the medicine in the incubator is evenly distributed due to the shaking, and precipitation is prevented from occurring in the medicine.

[0022] 5. The present invention achieves the purpose of further draining the medicine after use and assisting the seedlings to return to the center position of the incubator after drainage by arranging an electromagnetic part at the upper end of the fixed plate. When in use, the incubator moved to the upper end of the inclined drainage part is controlled by the electromagnetic part to tilt and drain the medicine inside.

[0037] like Figures 1 to 10 As shown, according to the present invention, a root soaking device for preventing and controlling pests and diseases during seedling transplanting is provided, comprising: a base 1, which has a square cavity for accommodating medicine; a fixed plate 2, which is fixedly connected to the middle of the base 1 and forms a cavity with the bottom of the base 1, and the fixed plate 2 comprises an inclined drainage part 201, a horizontal filtering part 202, an inclined transition part 203, a horizontal soaking part 204 and an inclined sedimentation part 205, which are connected end to end in sequence to form a stepped structure; a circulating chain 3, which is symmetrically arranged on both sides of the base 1, and the circulating chain 3 is bent along the outer shape of the fixed plate 2 on one side close to the fixed plate 2, and the other side is vertically square. The circulating chain 3 is set in the direction, and a plurality of positioning pins 4 are fixedly connected to the middle of the circulating chain 3.

The incubator 5 can rotate relative to the circulating chain 3 through the hinge groove 6 and the positioning pin 4, and the bottom of the hinge groove 6 is higher than the edge height of the incubator 5; the incubator 5 The first permanent magnet part 7 and the second permanent magnet part 8 are fixedly connected at the bottom. The weight of the first permanent magnet part 7 and the second permanent magnet part 8 is greater than the weight of the seedlings in the incubator 5, so that the incubator 5 is kept in an upward opening state due to gravity to prevent the incubator 5 from turning over. When the first permanent magnet part 7 at the lower end of the incubator 5 is close to the corresponding second permanent magnet part 8 at the lower end of the incubator 5, the incubator 5 swings; the circulating chain 3 can drive the incubator 5 to circulate, and make the incubator 5 pass through the inclined drainage part 201, the horizontal filtering part 202, the inclined transition part 203, the horizontal immersion part 204 and the inclined sedimentation part 205 in sequence.

[0038] It should be noted that during use, when the incubator 5 is located in the vertical section of the circulating chain 3, the incubator 5 is kept open upwards due to the weight of the first permanent magnet 7 and the second permanent magnet 8. Fig. 9In the state, the first permanent magnet part 7 and the other second permanent magnet part 8 at the bottom of the two incubators 5 close to each other attract / repel each other, causing the two incubators 5 to flip over. At the same time, driven by the circulating chain 3, the relative positions of the two incubators 5 change. When the magnetic force range of the first permanent magnet part 7 and the second permanent magnet part 8 is out of alignment, the incubator 5 is reset under the influence of gravity and shakes slightly, so that the medicine inside the incubator 5 is further mixed and the substances in the medicine in the incubator 5 are prevented from precipitating.

[0039] It should be pointed out that the first permanent magnet part 7 and the second permanent magnet part 8 cooperate with each other to make the incubator 5 flip and shake with a smaller amplitude, and the medicine in the incubator 5 will not overflow.

[0040] The spray rack 10 is configured as a door-type structure and is located above the base 1. A plurality of atomizing nozzles 11 for spraying medicine are provided at the top of the interior of the spray rack 10. The atomizing nozzles 11 are placed above the moving path of the incubator 5 and are used to spray the medicine in the incubator 5, replenish the medicine in the incubator 5, and ensure that the seedlings can evenly receive the medicine, thereby improving the uniformity of the distribution of the medicine.

[0041] Specifically, it also includes: a first partition 12, the first partition 12 is located inside the base 1 and defines a water replenishment chamber 13 with the inner wall of the base 1, and the water replenishment chamber 13 is used to store newly added medicine; a second partition 14, the second partition 14 is set to a "∩"-shaped structure and is located in the middle of one side of the first partition 12 away from the water replenishment chamber 13, the second partition 14 and the bottom inner wall of the base 1 define a mixing chamber 15, and the mixing chamber 15 is used to add part of the new medicine to the used medicine to ensure The drug concentration of the medicine solution, the second partition 14 and the bottom end of the horizontal filter part 202 define a filter chamber 16, and the filter chamber 16 is used to guide the used medicine to flow back and reduce the consumption of the medicine solution; the third partition 17, the third partition 17 is located between the second partition 14 and the inclined transition part 203, the third partition 17 and the inner wall of the base 1 define a medicine circulation chamber 18, and the medicine circulation chamber 18 is used to store the mixed medicine in the mixing chamber 15 and enable it to enter the incubator 5.

[0042] More specifically, it also includes: a circulation pump 26, which is a water pump, which is a prior art and will not be described in detail here. During use, the circulation pump 26 is electrically connected to a corresponding controller and a power supply, and the circulation pump 26 is located inside the medicine circulation chamber 18. The output end of the circulation pump 26 is located on the surface of the inclined transition portion 203, and the input end of the circulation pump 26 is connected to the medicine circulation chamber 18 and the mixing chamber 15 through a three-way pipe 27. During use, when the incubator 5 is placed in the horizontal immersion portion 204, the circulation pump 26 connects the medicine circulation chamber 18 with the mixing chamber 15. The medicine is extracted and transported to the upper end of the horizontal immersion part 204, so that the mixed medicine can enter the incubator 5; valves are provided between the mixing chamber 15 and the filtering chamber 16, between the mixing chamber 15 and the three-way pipe 27, and between the mixing chamber 15 and the water replenishing chamber 13. The valve can be set as a solenoid valve, and the opening and closing control is performed according to the consumption of the medicine during the circulation process of the incubator 5. Moreover, the solenoid valves are set as one-way valves to control the circulation direction of the medicine. The solenoid valves are prior art and will not be described in detail here. During use, the solenoid valves are electrically connected to the corresponding controller and power supply.

[0043] Specifically, it also includes: a conduit 30, which is located on the outside of the spray rack 10 and connects the atomizing nozzle 11 with the output end of the circulating pump 26. When the incubator 5 moves under the spray rack 10, the circulating pump 26 transports the medicine to the atomizing nozzle 11 through the conduit 30, and the atomizing nozzle 11 can spray the medicine above the seedlings.

[0044] More specifically, it also includes: a drainage hole 28, which is opened at the top of the inner wall of one side of the incubator 5, and the bottom of the drainage hole 28 is at a certain distance from the bottom of the inner side of the incubator 5, so that an appropriate amount of medicine can be stored in the incubator 5. When the incubator 5 passes through the inclined drainage part 201, the medicine is discharged through the drainage hole 28; a baffle 29, which is located inside the incubator 5 and overlaps with the position of the drainage hole 28.

[0045] It should be noted that the drainage hole 28 is arranged in the forward direction of the movement of the incubator 5. When the incubator 5 moves in the horizontal immersion portion 204, the moving incubator 5 can speed up the speed at which the medicine enters through the drainage hole 28. The setting of the baffle 29 allows the medicine to be guided by the baffle 29 to change direction when passing through the drainage hole 28, so as to avoid the medicine directly impacting the roots of the seedlings and causing root damage.

[0046] Specifically, it also includes: a strip through groove 19, which runs through the middle of the horizontal filter part 202. It should be noted that the inclined drainage part 201 is arranged in an inclined state as a whole. When the incubator 5 is driven by the circulating chain 3 to reach the upper end of the inclined drainage part 201, the incubator 5 is tilted as a whole and the medicine in the incubator 5 is discharged. In this process, the medicine flows forward and flows through the horizontal filter part 202, and then the medicine enters the filter chamber 16 through the strip through groove 19; the impurity filter screen 20, the impurity filter screen 20 is arranged in the middle of the filter chamber 16, and the medicine discharged from the incubator 5 enters the filter chamber 16 after passing through the strip through groove 19, and the impurities in the medicine are filtered out by the impurity filter screen 20.

[0047] More specifically, it also includes: a wave plate 21, which is fixedly connected to the bottom of the second permanent magnet part 8, and the bottom of the wave plate 21 is flush with the bottom of the first permanent magnet part 7; a collision rod 22, which is rotatably connected in the filter chamber 16, and is provided with a plurality of through holes 23, and the upper end of the collision rod 22 passes through the inclined drainage part 201 through the through hole 23, and the upper end of the collision rod 22 can contact with the wave plate 21, and the other end of the collision rod 22 can contact with the impurity filter 20. During use, when the incubator 5 is moved to the upper end of the inclined drainage part 201 under the influence of the circulating chain 3, the incubator 5 tilts to one side, and at the same time At this time, the wave plate 21 at the bottom of the second permanent magnet part 8 contacts the upper end of the collision rod 22, and then the incubator 5 continues to slide along the inclined drainage part 201, and the collision rod 22 is repeatedly swung by the influence of the wave plate 21. In this process, the impurity filter 20 is subjected to force to generate vibration, thereby improving the filtering performance of the impurity filter 20 and reducing the risk of clogging of the impurity filter 20; the elastic membrane 24 is fixedly connected to the upper end of the through hole 23, and the middle part of the collision rod 22 passes through the middle part of the elastic membrane 24 and is fixedly connected to the elastic membrane 24. The setting of the elastic membrane 24 enables the collision rod 22 to be reset, and separates the inclined drainage part 201 from the filter chamber 16, so that the medicine can completely pass through the impurity filter 20.

[0048] Specifically, it also includes: a sedimentation filter 25, which is arranged in the middle of the inclined sedimentation part 205. When the medicine is circulated between the medicine circulation chamber 18 and the horizontal immersion part 204, impurities in the medicine are settled in the inclined sedimentation part 205 and filtered out by the sedimentation filter 25 to avoid the sediment affecting the root immersion treatment of the seedlings.

[0049] In summary, when the seedlings are subjected to root immersion treatment with medicinal solution, the seedlings are placed in multiple cultivation boxes 5 through culture pots, and medicinal solution is added to the water replenishment chamber 13. During use, the circulation pump 26 and the motor are started to make the circulating chains 3 on the left and right sides move along the supporting sprocket 31. At this time, the cultivation box 5 moves with the circulating chain 3.

[0050] During use, when the incubator 5 is placed in the horizontal immersion section 204, the circulation pump 26 draws out the medicine in the medicine circulation chamber 18 and the mixing chamber 15 and transports it to the upper end of the horizontal immersion section 204. At this time, the medicine enters the incubator 5 through the drainage hole 28, and then the incubator 5 continues to move following the circulation chain 3, and the next incubator 5 moves to the upper end of the horizontal immersion section 204 to add medicine.

[0051] When the incubation box 5 moves under the spray rack 10, the circulation pump 26 transports the medicine to the atomizing nozzle 11 through the conduit 30. The atomizing nozzle 11 can spray the medicine above the seedlings, replenish the medicine in the incubation box 5, and ensure that the seedlings can evenly receive the medicine, thereby improving the uniformity of the distribution of the medicine.

[0052] When the incubator 5 is in the vertical section of the circulating chain 3, two discontinuous incubators 5 are placed at the same height, and the first permanent magnet part 7 and the other second permanent magnet part 8 at the bottom of the two incubators 5 close to each other attract / repel each other, causing the two incubators 5 to flip over. When the relative positions of the two incubators 5 change, when the magnetic force range of the first permanent magnet part 7 and the second permanent magnet part 8 are out of alignment, the incubator 5 is reset under the influence of gravity and shakes slightly under the influence of inertia to prevent the substances in the medicine in the incubator 5 from precipitating.

[0053] When the incubator 5 is driven by the circulation chain 3 to reach the upper end of the inclined drainage portion 201, the incubator 5 is tilted as a whole and the medicine in the incubator 5 is discharged through the drainage hole 28. At the same time, the setting of the baffle 29 allows the medicine to be guided by the baffle 29 to change direction when passing through the drainage hole 28 to avoid the medicine directly impacting the roots of the seedlings and causing root damage. In this process, the medicine flows forward and flows through the horizontal filter portion 202, and then the medicine enters the filter chamber 16 through the strip groove 19, and the impurities in the medicine are filtered out by the impurity filter 20. The filtered medicine enters the mixing chamber 15, and then the medicine in the water replenishment chamber 13 enters the mixing chamber 15 by controlling the valve, so as to increase the drug concentration of the medicine in the mixing chamber 15, and then the circulation pump 26 can extract the mixed medicine and inject it into the atomizing nozzle 11 and the upper side of the inclined transition portion 203, so as to achieve the purpose of reciprocating circulation in sequence.

[0054] When in use, when the incubator 5 is moved to the upper end of the inclined drainage part 201 under the influence of the circulating chain 3, the wave plate 21 at the bottom of the second permanent magnet part 8 contacts the upper end of the collision rod 22, and then the incubator 5 continues to move, and the collision rod 22 swings repeatedly under the influence of the wave plate 21. During this process, the impurity filter 20 is subjected to force to vibrate, thereby improving the filtering performance of the impurity filter 20 and reducing the risk of clogging of the impurity filter 20.

[0055] In the second embodiment, during actual use, the seedlings in the cultivation box 5 are easily damaged and produce impurities, and the impurities cannot be completely discharged when passing through the inclined drainage portion 201. In addition, when the cultivation box 5 is at the upper end of the inclined drainage portion 201, the overall inclination causes the seedlings inside to slide to one side, resulting in uneven distribution of the seedlings inside, affecting the stability of the cultivation box 5, and failing to ensure effective contact between the seedlings and the medicine.

[0056] In combination with the above embodiments, in order to solve the problem that impurities cannot be further discharged and seedlings cannot be reset during use, Figures 9 to 12 , and also includes an electromagnetic part 9, which is fixedly connected to the upper end of the inclined drainage part 201 and is used to control the flipping of the incubator 5. The electromagnetic part 9 is a prior art and will not be described in detail here. During use, the electromagnetic part 9 is electrically connected to the corresponding controller and power supply.

[0057] It should be noted that the hinge groove 6 is an oblong notch, and the positioning pin 4 can rotate or slide relative to the hinge groove 6 to reduce the inclined angle of the inclined drainage portion 201.

[0058] In summary, when the incubator 5 slides downward to the upper end of the inclined drainage portion 201 during use, the electromagnetic portion 9 is energized to attract the second permanent magnet portion 8, and the incubator 5 flips to one side. Fig.12 In the state (a), the medicine inside is discharged through the drainage hole 28, and then the circulating chain 3 makes the incubator 5 continue to move. During this process, the wave plate 21 contacts the collision plate. When the magnetic force range of the second permanent magnet part 8 and the electromagnetic part 9 are separated, the magnetic force range of the first permanent magnet part 7 overlaps with the electromagnetic part 9. At this time, the electromagnetic part 9 and the first permanent magnet part 7 repel each other, causing the incubator 5 to further flip over. Fig.12 In the state (b), the positioning pin 4 is placed at the bottom of the hinge groove 6, and the impurities in the incubator 5 are further discharged during this process.

[0059] Then, when the first permanent magnet part 7 and the electromagnetic part 9 are within the magnetic force range, the magnetic pole direction of the electromagnetic part 9 is changed so that the electromagnetic part 9 attracts the first permanent magnet part 7. Fig.12 In the middle (c) state, the incubator 5 is flipped and tilted to the other side to reset the seedlings in the incubator 5 . When the seedlings slide to the middle of the incubator 5 , the magnetic poles of the electromagnetic part 9 disappear. At this time, the seedlings are evenly distributed in the middle of the incubator 5 .

[0060] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
