Description

Technical Field

[0001] The invention belongs to the field of prevention and control of alien invasive plants, and particularly relates to a spraying device for preventing and control of alien invasive plants. Background Art

[0002] Invasive alien plants are not native to a region but are introduced or spread to new areas for various reasons, posing a threat to the local ecosystem. They can disrupt the original ecological balance, squeeze the living space of native plants, and even cause the extinction of some species.

[0003] Currently, invasive plants are typically controlled by spraying herbicides. Existing technologies often use sprayers for this purpose. However, due to the large variety and scattered distribution of invasive plants, different agents are required for different invasive species. For mixed invasive species, a combination of different agents is sometimes necessary for optimal control. Current sprayers typically use separate spray tanks, making it difficult to change and mix agents. Summary of the Invention

[0034] The following is a combination of the embodiments of the present invention Figures 1-8 , clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0035] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figure 1-Figure 3 , a spraying device for preventing and controlling invasive alien plants, comprising an outer cylinder 1, a temporary storage bin 2, an inner cylinder 11, a top plate 3, a bottom plate 4, a partition 39, a drain pipe 12 and a switch mechanism;

[0037] The outer cylinder 1 is sleeved on the inner cylinder 11, and an annular chamber is formed between the outer cylinder 1 and the inner cylinder 11. A plurality of partitions 39 are provided in the annular chamber. The ends of the plurality of partitions 39 are fixedly connected to the inner cylinder 11 and the inner cylinder 11, and the annular chamber is evenly divided into a plurality of independent chambers. The plurality of independent chambers are used to store different medicines. The inner cylinder 11 and the top of the inner cylinder 11 are fixedly connected to the top plate 3, and the bottom of the inner cylinder 11 and the bottom of the inner cylinder 11 are fixedly connected to the bottom plate 4.

[0038] The bottom plate 4 is fixedly connected to a plurality of drain pipes 12 , and the plurality of drain pipes 12 are connected to the independent chambers in a one-to-one correspondence. The switch mechanism is connected to the drain pipes 12 and is used to open and close the drain pipes 12 ;

[0039] The bottom of the outer cylinder 1 is fixedly connected to the temporary storage bin 2, the temporary storage bin 2 opening is facing upward, and the bottom plate 4 is located in the opening of the temporary storage bin 2. The opening of the temporary storage bin 2 is adapted to the inner size of the outer cylinder 1, and the drain pipe 12 and the switch mechanism are located in the opening of the temporary storage bin 2.

[0040] The present invention uses multiple partitions 39 to divide the annular chamber into multiple independent chambers, each capable of storing a different agent. This design allows the device to carry multiple agents simultaneously to combat different types of invasive plants. Furthermore, a switch mechanism allows agents in different independent chambers to enter the temporary storage compartment 2, allowing for mixing of different agents and adjusting their concentration and composition as needed to combat different invasive plants. The agents referred to in this invention are conventional. Mixing herbicides is an effective agricultural technique designed to improve weed control efficiency, expand the range of weed control, reduce the number of applications, and lower costs. By combining two or more herbicides, this method overcomes the limitations of a single herbicide and achieves better control effectiveness. The agents stored in the independent chambers can include a variety of liquid media, such as water, selective herbicides, lethal herbicides, contact herbicides, systemic herbicides, sodium chlorate, borax, arsenic salts, trichloroacetic acid, glyphosate, and defoliant. The specific agents selected and how they are combined should be determined based on actual conditions.

[0041] Furthermore, the temporary storage bin 2 is connected to a water pump 5, the output end of which is connected to an elastic hose 6. A water spray pipe 7 is provided at the end of the elastic hose 6, and an atomizing nozzle is provided at the end of the water spray pipe 7. The water spray pipe 7 is fixedly connected to a mounting pipe 8, which is sleeved on a rotating rod 9. The bottom of the rotating rod 9 is rotatably connected to a mounting plate. The side of the rotating rod 9 is rotatably connected to one end of a telescopic rod 10, and the other end of the telescopic rod 10 is rotatably connected to the mounting plate.

[0042] In specific implementation, the angle of the rotating rod 9 can be adjusted by the telescopic rod 10, so that the pitch angle of the water spray pipe 7 can be adjusted, thereby adjusting the pitch spray angle of the atomizing nozzle. The mounting pipe 8 and the rotating rod 9 can be locked by screws, so that the water spray pipe 7 can be removed and sprayed manually. Figure 1 The mounting plate of the present invention can be fixed on the vehicle body to achieve the effect of spraying medicine over a large area.

[0043] like Figure 2 、 Figure 3 、 Figure 5 A hollow tube 23 is slidably provided in the inner tube 11 , and the hollow tube 23 passes through the top plate 3 and the bottom plate 4 ;

[0044] The switch mechanism includes a sliding plate 21, a connecting rod 15, and a sliding switch tube 13. The sliding plate 21 is an arc-shaped structure, and multiple sliding plates 21 are provided. The multiple sliding plates 21 are arranged around the inner wall surface of the inner tube 11, and the hollow tube 23 is located in the hollow portion formed by the multiple sliding plates 21. The bottom of the sliding plate 21 passes through the bottom plate 4, and the bottom of the sliding plate 21 is fixedly connected to the connecting rod 15. The connecting rod 15 is fixedly connected to the bottom side of the sliding switch tube 13. The top of the sliding switch tube 13 passes through the bottom plate 4. The top of the sliding switch tube 13 can be slidably inserted into one of the drain pipes 12. The sliding switch tubes 13 on the multiple switch mechanisms are inserted into the drain pipes 12 in a one-to-one correspondence.

[0045] The sliding switch tube 13 is a hollow structure, the top of the drain pipe 12 is a closed end, a drainage hole 14 is set on the side of the drain pipe 12, and the drainage hole 14 is a waist-shaped hole. The sliding switch tube 13 covers the drainage hole 14. When the sliding plate 21 slides downward, the top of the sliding switch tube 13 is located within the coverage range of the drainage hole 14, so that the medicine passes through the drainage hole 14 into the sliding switch tube 13 and is discharged.

[0046] Specifically, a plurality of holes through which the sliding plates 21 pass are respectively provided on the top plate 3 and the bottom plate 4, and the size of the holes is adapted to the hollow part of the inner cylinder 11. The plurality of sliding plates 21 are surrounded together to form a hollow shaft structure. The number of sliding plates 21 is the same as the number of independent cavities. One sliding plate 21 controls the output of the medicine of one independent cavity. The drainage hole 14 is a vertical long waist-shaped hole. When the sliding plate 21 is in the initial state, the sliding switch tube 13 covers the drainage hole 14 to form a sealing structure, and the medicine cannot be output. Figure 7 By sliding the sliding plate 21 downward, the top of the sliding switch tube 13 is located within the coverage of the drainage hole 14, and the medicine enters the sliding switch tube 13 through the drainage hole 14 and is discharged. In specific implementation, different independent chambers can be controlled to output medicine by sliding different sliding plates 21.

[0047] Furthermore, a plurality of protrusions 38 are fixedly connected to the inner wall surface of the inner cylinder 11 , and the sliding plate 21 is located between two adjacent protrusions 38 .

[0048] The protrusions 38 abut against the outer wall of the fixed tube 22, and the protrusions 38 form a limit function to prevent the sliding plate 21 from rotating. An arc-shaped channel is formed between two adjacent protrusions 38, and the sliding plate 21 is an arc-shaped structure and is adapted to the arc-shaped channel.

[0049] like Figure 2 、 Figure 3 、 Figure 6 The fixed tube 22 is sleeved on the hollow tube 23, and the fixed tube 22 is located between the hollow tube 23 and the sliding plate 21;

[0050] The switch mechanism further includes a first stopper 16, a switch mechanism spring 17, a slider 18, a limit rod 19, and a second stopper 20; the first stopper 16 and the second stopper 20 are fixedly connected to the connecting rod 15, the slider 18 is slidably disposed on the connecting rod 15, the slider 18 is located between the first stopper 16 and the second stopper 20, the slider 18 abuts the second stopper 20, and the side of the slider 18 away from the sliding plate 21 abuts the switch mechanism spring 17, the switch mechanism spring 17 is sleeved on the connecting rod 15, and the switch mechanism spring 17 abuts the first stopper 16;

[0051] The bottom of the slider 18 is fixedly connected to the top of the limiting rod 19, and a wedge-shaped portion is provided at the bottom of the limiting rod 19;

[0052] A plurality of limiting components are provided on the side of the fixed tube 22, and the positions of the plurality of limiting components correspond one to one with the limiting rod 19. The limiting components include a limiting block 24, a limiting spring 25, a limiting sleeve 26 and a limiting slide 27; the side of the fixed tube 22 is fixedly connected to the limiting sleeve 26, and the limiting slide 27 is slidably inserted in the limiting sleeve 26, and the inner end of the limiting slide 27 abuts the hollow tube 23. The side of the fixed tube 22 is provided with a through hole for the limiting slide 27 to pass through, and the end of the limiting slide 27 is fixedly connected to the limiting block 24, and the limiting spring 25 is sleeved on the limiting slide 27. The two ends of the limiting spring 25 are respectively fixedly connected to the limiting block 24 and the limiting sleeve 26, and the limiting spring 25 is in a stretched state;

[0053] When the sliding plate 21 slides downward, the wedge-shaped portion of the limiting rod 19 is engaged with the limiting block 24, thereby restricting the sliding plate 21 from moving upward.

[0054] A snap-fitting opening 37 is provided on the side surface of the lower end of the hollow tube 23. The snap-fitting opening 37 is located above the limiting component. When the hollow tube 23 slides downward, the snap-fitting opening 37 faces the limiting slide bar 27, so that the inner end of the limiting slide bar 27 enters the snap-fitting opening 37, causing the limiting block 24 to avoid the limiting rod 19, and the sliding plate 21 is then reset.

[0055] When the hollow tube 23 is rotated, the engaging opening 37 is located directly above different limiting components, so as to correspondingly reset different sliding plates 21 .

[0056] In the present invention, the number of switch mechanisms, limiting components, sliding plates 21, drain pipes 12, sliding switch tubes 13 and independent cavities is the same, and their positions correspond one to one. The fixed tube 22 is a fixed component in the present invention. Under the action of the switch mechanism spring 17, the slider 18 is located near the sliding plate 21. The switch mechanism spring 17 plays a reset role. The wedge-shaped part at the bottom of the limiting rod 19 is adapted to the limiting block 24, and the contact surface of the wedge-shaped part and the limiting block 24 is an inclined surface. The bottom width of the limiting block 24 is smaller than the top width, and its width gradually decreases from top to bottom. A notch portion is provided on the top side of the wedge-shaped part, and the notch portion is used to form a limiting structure with the bottom surface of the limiting block 24.

[0057] During the movement of the sliding plate 21 from top to bottom, the wedge-shaped portion contacts the limit block 24, and then the switch mechanism spring 17 is compressed. When the wedge-shaped portion is located below the limit block 24, the notch at the top of the wedge-shaped portion abuts against the bottom surface of the limit block 24, thus preventing the sliding plate 21 from rising, forming a Figure 7 During the specific implementation, the staff moves the sliding plate 21 downward so that the limit block 24 cooperates with the wedge-shaped portion. At this time, the sliding plate 21 can be constrained, so that the medicine can be continuously discharged from the sliding switch tube 13, thereby realizing the function of continuous output of the medicine.

[0058] The clamping opening 37 is a waist-shaped hole structure, and the bottom surface of the clamping opening 37 is a wedge-shaped inclined surface, which is used to push the limiting slide bar 27 to reset. Figure 6 The width of the snap-fit opening 37 is smaller than the distance between two adjacent limiting blocks 24 (ie, the switch mechanism), which can prevent the snap-fit opening 37 from covering two limiting slide bars 27 at the same time, so that only one limiting slide bar 27 can enter the snap-fit opening 37 .

[0059] In specific implementation, when the continuous output of the medicine is completed, the staff can first rotate the hollow tube 23 to align the clamping opening 37 with the limiting slide 27 corresponding to a certain independent cavity, and then slide the hollow tube 23 downward to make the clamping opening 37 cover the limiting slide 27. Then, the limiting slide 27 moves inward under the action of the limiting spring 25, the limiting block 24 disengages from the wedge-shaped part, and the limiting rod 19 resets upward, forming a Figure 8 The hollow tube 23 then returns to its original position, and the wedge-shaped slope on the bottom of the engaging opening 37 pushes the limiting slide 27 back to its original position. The inner end of the limiting slide 27 returns to its original position and abuts against the hollow tube 23. Because the ratios of different medicines vary during mixing, the present invention can independently control the output and closing of each independent chamber, enabling the output of different medicines to be adjusted independently, facilitating control of the mixing ratio.

[0060] In addition, multiple limiting components can be set in the vertical direction, and the wedge-shaped part of the limiting rod 19 can cooperate with the limiting blocks 24 of different heights to control the height of the sliding switch tube 13, so that the opening of the drainage hole 14 can be adjusted to control the output speed of the medicine.

[0061] like Figure 4 The top of the hollow tube 23 passes through the fixed tube 22, the top of the fixed tube 22 is fixedly connected to the flange portion 32, and the flange portion 32 is fixedly connected to the top of the top plate 3 through the bracket 33. A pressure plate 30 is provided above the flange portion 32, and the pressure plate 30 is fixedly connected to the hollow tube 23. A return spring 31 is provided between the pressure plate 30 and the flange portion 32, and the return spring 31 is sleeved on the hollow tube 23.

[0062] The return spring 31 and the pressure plate 30 work together to support and return the hollow tube 23 .

[0063] Furthermore, the bottom of the hollow tube 23 passes through the fixed tube 22 , the bottom of the hollow tube 23 is fixedly connected to the stirring rod 40 , the stirring rod 40 is located in the temporary storage bin 2 , and the top of the hollow tube 23 is fixedly connected to the temporary dosing hopper 28 .

[0064] The top side of the hollow tube 23 is fixedly connected to a handle 29, which can be used to rotate and lift the hollow tube 23. The temporary drug hopper 28 can temporarily replenish the medicine that is not in the independent cavity, and the rotating hollow tube 23 can be used to stir the medicine through the stirring rod 40.

[0065] The hollow tube 23 of the present invention includes multiple functions. It can temporarily add medicine through the temporary medicine adding hopper 28, stir the medicine through the stirring rod 40, and can rotate and descend to control the reset of the switch mechanism.

[0066] Furthermore, the top of the sliding plate 21 can slide through the top plate 3, the top of the sliding plate 21 is fixedly connected to the pressure rod 34, the pressure rod 34 is slidably connected to the vertical rod 36, the bottom of the vertical rod 36 is fixedly connected to the top plate 3, and a lifting spring 35 is sleeved on the vertical rod 36, and the two ends of the lifting spring 35 respectively abut against the pressure rod 34 and the top plate 3.

[0067] The pressure rod 34 is used for workers to hold and press to slide the sliding plate 21 , the bracket 33 avoids the pressure rod 34 , and the lifting spring 35 is used to reset the pressure rod 34 and the sliding plate 21 .

[0068] The workflow of the present invention is as follows:

[0069] Depending on the area and type of invasive plants, manual or automatic spraying is selected. For automatic spraying, the mounting tube 8 and rotating rod 9 are screwed together, and the entire spraying device can be mounted on a vehicle. For manual spraying, the operator holds the mounting tube 8 and water pipe 7.

[0070] If there is no need to mix the medicine, the staff will slide the sliding plate 21 through the pressure rod 34 to make the sliding plate 21 move downward. The downward movement of the sliding plate 21 is divided into several gears to correspond to different medicine output rates. For example, when the sliding plate 21 moves to the lowest position, the wedge-shaped part of the limit rod 19 cooperates with the lowest limit block 24, and the medicine output rate is the highest at this time. After a certain amount of medicine is output to the temporary storage bin 2, the hollow tube 23 is rotated first and then lowered so that the clamping opening 37 is aligned with the limit slide 27 corresponding to the corresponding independent cavity. The limit block 24 is separated from the wedge-shaped part, and the limit rod 19 is reset upward to form a Figure 8 Afterwards, the hollow tube 23 is reset upwards. Finally, the water pump 5 is started and the spraying can be started.

[0071] When mixing medicines, the operator slides the sliding plates 21 corresponding to the individual chambers to continuously dispense and mix the medicines. When the required dosage of a particular medicine is reached, the operator rotates the hollow tube 23 so that the engaging opening 37 aligns with the corresponding limiting slide bar 27 of the corresponding independent chamber, and then lowers the hollow tube 23 to stop dispensing the medicine from that independent chamber. Once the dosage of medicines from the other independent chambers is reached, the other independent chambers are closed in sequence using the above method.

[0072] During the implementation process, temporary medicine addition can be performed through the temporary medicine adding hopper 28 , and the medicine can be stirred through the stirring rod 40 .

[0073] In addition, corresponding scale lines can be set on the outer wall of the outer cylinder 1 and the outer wall of the temporary storage bin 2 to observe the output volume of the medicine and the weight of the medicine in the temporary storage bin 2.

[0074] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
