Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a pesticide spraying device for field experiments. Background Art

[0002] When conducting field efficacy tests, it is often necessary to mix and spray multiple pesticides. However, existing sprayers are difficult to adapt to efficacy tests of multiple pesticides. Existing portable sprayers have only one liquid storage chamber, which can only hold a single pesticide at a time. When used again, they need to be cleaned before spraying different pesticides. When it is necessary to conduct efficacy comparison tests of multiple pesticides, if traditional sprayers are used, they need to be cleaned repeatedly, which is time-consuming, labor-intensive and time-consuming.

[0003] In response to the above technical problems, some scholars have proposed the idea of ​​using a multi-chamber sprayer. For example, the patent with authorization announcement number CN213095727 U announces a portable spray device for field pesticide efficacy testing, including a spray barrel and a spray rod. The interior of the spray barrel is integrally formed with at least three groups of partitions, and the three groups of partitions divide the spray barrel into four groups of cavities; the partitions inside the spray barrel divide the spray barrel into multiple cavities, so that test personnel can easily mix and hold a variety of pesticides.

[0004] Although the above scheme is feasible, there are still the following problems in actual operation: 1) The multi-chamber chamber is formed by using partitions. Since the chamber cannot be disassembled individually, when cleaning the residual liquid, it is necessary to fill the cavity with cleaning liquid and then shake the sprayer as a whole to clean the residual liquid in the cavity. This method is still inconvenient and time-consuming and labor-intensive; 2) It is impossible to achieve continuous and rapid replacement of agents. Since the chamber structure design is adopted, it must be cleaned before it can hold another agent. When a large number of agent comparison tests are required, this method is obviously unable to achieve continuous agent spraying operations, and it still has certain inconveniences when used.

[0038] like Figure 1-Figure 9 As shown, this embodiment proposes a pesticide spraying device for field experiments, including a box body 1, a pump body 15 and a spray rod 10. The box body 1 is a rectangular structure without a front panel, and the box body 1 has a cavity inside; a shoulder strap 14 is installed on the box body 1, which is a backpack structure; a water tank 17 and a main pipe 18 are arranged in the box body 1, and a water injection port 11 is provided on the top of the water tank 17, and clean water can be injected into the water tank 17 through the water injection port 11; one end of the main pipe 18 is connected to the water tank 17. In this embodiment, the main pipe 18 is arranged in a serpentine shape, and the water inlet end of the main pipe 18 extends into the position of the water tank 17 near the inner bottom, and the other end of the main pipe 18 is connected to the input end of the pump body 15, and the output end of the pump body 15 is connected to the spray rod 10.

[0039] In this embodiment, a plurality of groups of holders 9 for clamping reagent bottles are provided in the box body 1, and the holders 9 are connected to the inner wall of the box body 1; the reagent bottles are detachably connected to the holders 9 to meet the needs of convenient installation and disassembly; in this embodiment, the number of holders 9 can be set to 4-6 groups or more, arranged in an upper and lower manner; the bottom of the reagent bottle is connected to a drain pipe 21, and a valve 20 is provided on the drain pipe 21, and the valve 20 can be a manual valve 20, such as a mini ball valve, a micro valve, etc.; the reagent bottle is used to contain medicines, and the drain valve is used to divert the medicines. The purpose of setting the valve 20 is to close the valve 20 when the reagent bottle is not installed, so that a storage space is formed inside the reagent bottle.

[0040] The bottom end of the drain pipe 21 is detachably connected to one end of the branch hose 7. In this embodiment, the branch hose 7 can be threaded or plugged with the bottom end of the drain pipe 21, including but not limited to the use of a slip-on quick connector. The branch hose 7 is provided with a first electric valve 6, and the other end of the branch hose is connected to the main line 18. The first electric valve 6 realizes the connection and disconnection between the branch hose 7 and the main line 18; the main line 18 is provided with a second electric valve 19, and along the water flow direction, the second electric valve 19 is arranged before all the branch hoses 7, that is, the clean water in the water tank 17 must pass through the second electric valve 19 to reach the branch hose 7; the second electric valve 19 is arranged before all the branch hoses 7 to prevent backflow.

[0041] The structure of the fixator 9 can be various, such as a clamp, Velcro fixation, etc., but considering the convenience of operation and stability after fixation, the fixator 9 can adopt the following structure:

[0042] The holder 9 includes a base 91, which is fixedly connected to the inner wall of the box body 1; two clamping arms 92 are hinged on the base 91, and the clamping arms 92 are connected to the base 91 through a hinge shaft 93, and a lever fulcrum is formed at the hinge shaft 93; a spring 95 is connected between the clamping arms 92; the ends of the two clamping arms 92 have arc-shaped openings, and when the two clamping arms 92 are closed, the two clamping arms 92 form a clamping opening 94 for clamping a reagent bottle.

[0043] In this embodiment, the spring 95 is a tension spring, and the function of the spring 95 is to provide tension, thereby achieving clamping; Figure 8 In this embodiment, the tension spring is arranged in the area between the hinge point and the clamping opening 94. When the clamp arm 92 is closed, the tension spring has a tensile force, relying on which the reagent bottle can be clamped and fixed; when the reagent bottle needs to be removed or replaced with a new one, the two clamp arms 92 need to be pried apart, and the tension spring is further stretched to enlarge the clamping opening 94, so that the reagent bottle can be taken in and put in.

[0044] In this embodiment, at least one set of partitions 3 is provided in the box 1, and the partitions 3 are fixedly connected to the inner wall of the box 1, and the partitions 3 divide the space inside the box 1. The accompanying drawings show two sets of partitions 3, which can separate two areas for placing reagent bottles, arranged up and down, and a total of 6 groups of reagent bottles can be placed, so that 6 groups of drug control groups can be formed.

[0045] Considering that the reagent bottle is relatively heavy after being loaded with medicine, although it can be fixed in the circumferential direction by clamping alone, the positioning effect of the upper and lower positions is not good, and the reagent bottle is likely to slip. For this reason, a support plate 4 is also provided in the box body 1, and the support plate 4 is fixedly connected to the inner wall of the box body 1. The support plate 4 is provided with a notch 5, and the drain pipe 21 can freely enter and exit from the notch 5. The partition 3 is provided with two groups, which are used to support the reagent bottle and play the role of supporting weight, and the fixer 9 mainly plays the role of positioning to prevent skewness, and the two are used in conjunction with each other.

[0046] The front of the box body 1 is provided with a detachable protective cover plate 2, which is provided with an operation port for conveniently taking in and putting in the reagent bottle. The protective cover plate 2 is fixed by screws, which is convenient for disassembly. The protective cover plate 2 mainly protects the internal water tank 17, the pump body 15 and other components.

[0047] The side wall of the box body 1 has a switch panel 12, on which a controller and a plurality of control switches are arranged; a battery 16 is also arranged in the box body 1, and the battery 16 is electrically connected to the switch panel 12 and the pump body 15 respectively; the controller is controlled and connected to the control switch, the first electric valve 6 and the second electric valve 19.

[0048] In this embodiment, there are 6 groups of reagent bottles, 6 groups of first electric valves 6, and 6 groups of corresponding control switches; in addition, the control switches also include a group of power switches and pump body 15 control switches and a group of second electric valve 19 control switches, and the total number of control switches is 9.

[0049] In this embodiment, the controller is also provided with a wireless transmission module, and the controller realizes remote control connection with the remote control terminal through the wireless transmission module. For special users, such as those with disabled arms and fingers, who are not convenient to press the switch, a remote control can be used for operation. In this embodiment, the wireless transmission template can be a Bluetooth module or a LoRa module; the remote control terminal can be a remote control, etc.

[0050] The advantages of the solution are as follows:

[0051] By setting a number of detachable reagent bottles, the reagent bottles are clamped and fixed by the fixing device 9, which is convenient for disassembly and assembly. Compared with the design method of forming a chamber in the prior art, the utility model can disassemble the reagent bottle for offline processing when cleaning the residual liquid medicine, and no longer needs to be shaken as a whole, which saves time and effort and is more convenient to clean. Through the designed fixing device 9 and the detachable reagent bottle, when conducting a large number of drug comparison tests, the drug bottle 8 can be replaced continuously and quickly, and the continuous drug spraying operation can be realized, the intermediate cleaning link is omitted, and it is more convenient to use and can improve efficiency.

[0052] Directions:

[0053] When conducting a comparative test of the efficacy of the drugs, clean water is injected into the water tank 17, and six groups of reagents are prepared. The prepared reagents are poured into a reagent bottle respectively, and the reagent bottle is placed on the fixture 9 for clamping and fixing; the corresponding valves 20 under each reagent bottle are opened; the device is carried on the back, the first electric valve 6 corresponding to one of the reagent bottles is opened, the second electric valve 19 is closed, and the pump body 15 is started. The pump body 15 draws the reagent in the reagent bottle for spraying; when the spraying is completed; the first electric valve 6 corresponding to the reagent bottle is closed, the second electric valve 19 is opened, the pump body 15 is started, and clean water is drawn to flush the pipeline. After the flushing is completed, the second electric valve 19 is closed; then the first electric valve 6 corresponding to a reagent bottle is opened, the pump body 15 is started, and spraying is carried out; the above process is repeated until all the reagents are sprayed.

[0054] Embodiment 2:

[0055] Continue to refer to the attached Figure 1-Figure 9 In this embodiment, other structures are the same as those in the first embodiment, except that, in this embodiment, the spring 95 in the fixer 9 is a compression spring; the compression spring is arranged between the hinge point and the clamping opening 94; in the initial state, relying on the elastic force of the compression spring, the clamping arm 92 is open; a slider 97 is slidably connected to the base 91, and both sides of the slider 97 have inclined surfaces, and one end of the two groups of clamping arms 92 are respectively in contact with the corresponding inclined surfaces; when the slider 97 is moved, one end of the clamping arm 92 slides along the inclined surface, and the clamping arm 92 can swing around the hinge point; the slider 97 is also connected to a driving mechanism for driving the slider 97 to move and positioning the slider 97.

[0056] The driving mechanism includes a boss 96 fixedly connected to the top of the base 91, and the boss 96 is slidably connected to a guide rod 98, one end of the guide rod 98 is connected to the slider 97; the other end of the guide rod 98 is rotatably connected to a bolt rod 99, and the guide rod 98 and the bolt rod 99 can rotate relative to each other; the base 91 is fixedly connected to a support 910, and the bolt rod 99 is threadedly connected to the support 910; the box wall of the box body 1 is provided with a through opening 13 corresponding to the position of the threaded rod.

[0057] When the reagent bottle needs to be clamped, the reagent bottle is placed in the corresponding position, and then the bolt rod 99 is screwed from the opening 13. The rotation of the bolt rod 99 will drive the guide rod 98 to move, and the movement of the guide rod 98 will drive the slider 97 to move. When the slider 97 slides, the clamping arm 92 slides along the small end of the slider 97 to the large end. At this time, the two clamping arms 92 will form a closed state, the compression spring will be compressed, and the reagent bottle will be well clamped and fixed.

[0058] Application results:

[0059] The holder 9 adopts a clamping method of a clamping arm 92, which is easy to operate and firmly clamped. The protective cover plate 2 with an operation port is adopted, which is convenient for taking and placing. The driving mechanism set in the holder 9 can drive the slider 97 to move and position the slider 97. The driving mechanism adopts a bolt rod 99, and a through hole 13 is opened on the box wall, which is convenient for controlling the slider 97 through the through hole 13. The design is reasonable, convenient for users to operate, and does not affect the use of carrying.

[0060] Practical Application:

[0061] Research direction: Study the effect of gibberellin concentration on potato flowering

[0062] Experimental method: The designed gibberellin concentrations are 0ppm, 30ppm, 60ppm, 90ppm, 120ppm, and 150ppm. The spraying time is the bud formation period of the potato mother plant, once every 5 days, for 3 consecutive times. Five potatoes are sprayed for each concentration treatment, and the spraying is repeated 3 times.

[0063] The test varieties are: 16ab138 (Japanese variety, No. 29), Xisen 6 (No. 54), and Jinyin 8 (No. 53).

[0064] Test equipment: The pesticide spraying device for field test in the above embodiment was used.

[0065] Test results:

[0066] Table 1 Effects of different gibberellin concentrations on potato flowering

[0067]

[0068] As can be seen from Table 1, when the gibberellin concentration was 90ppm, 120ppm, and 150ppm, the treatments did not bloom, and the buds appeared in the 90ppm treatment, but the buds fell off. At 30ppm and 60ppm, the plants all bloomed, and the water treatment did not bloom.

[0069] Test conclusion:

[0070] Gibberellic acid can increase the height of potato plants; when the gibberellin concentration is ≥90ppm, it affects the normal growth of potatoes and causes severe premature aging; gibberellin concentrations of 30ppm and 60ppm can promote potato flowering, but the effect is not obvious.
