[0035] Embodiment, referring to Figure 1 , which is an embodiment of the present invention, a field test device for pressing fertilizers and pesticides by using an electric sprayer is proposed, which is used to connect with the drip irrigation pipe 17. The inlet end of the drip irrigation pipe 17 has a reserved connection port 18, and includes a liquid storage tank 1 and an electric sprayer 2. The liquid storage tank 1 is used to hold the fertilizer and pesticide liquid, and the liquid storage tank 1 has a liquid outlet; the inlet end of the electric sprayer 2 is used to communicate with the liquid outlet of the liquid storage tank 1, and the outlet end of the electric sprayer 2 is used to communicate with the reserved connection port 18.

[0036] In this embodiment, the liquid outlet of the liquid storage tank 1 is located at the bottom of its side wall. The electric sprayer 2 can provide high-pressure spraying to evenly spray the fertilizer and pesticide liquid into the drip irrigation pipe 17. When multiple drip irrigation pipes 17 are needed in the field, the main pipe 19 can be used to connect multiple drip irrigation pipes 17 together, and the main pipe 19 is used to supply water to each drip irrigation pipe 17. When installing the drip irrigation system, reserved access ports 18 are provided on each drip irrigation pipe 17 to facilitate the connection of the electric sprayer 2 to the drip irrigation pipe 17. Before applying fertilizers or pesticides, the fertilizers or pesticides are diluted and dissolved in the liquid storage tank 1 in advance according to the required dosage. The working pressure and flow rate of the electric sprayer 2 are adjusted. Under the action of the electric sprayer 2, the liquid in the liquid storage tank 1 is evenly sprayed into the drip irrigation pipe 17 through the reserved access port 18, and the liquid is evenly applied to the soil through the drip irrigation pipe 17. For each experimental field plot with different treatments, this device can be connected at different reserved positions of the drip irrigation pipe 17 to simultaneously apply different types and amounts of fertilizers and pesticides. Moreover, the drip irrigation pipe 17 can directly transport the liquid to the roots of the crops, ensuring that each crop can obtain uniform nutrients and drugs, effectively reducing the usage amount of fertilizers and pesticides, improving the utilization rate of fertilizers and pesticides, and thus achieving efficient fertilization and pesticide application. It can be used to meet the experimental requirements of drip irrigation soil improvers for saline-alkali land, and can also be used for fertilization and pesticide application in small-area field experiments. When a Venturi fertilizer applicator is installed in the drip irrigation system, if the fertilization pressure difference of the Venturi fertilizer applicator is insufficient, the electric sprayer 2 can be connected to the Venturi fertilizer applicator to overcome the problem of insufficient pressure difference of the Venturi fertilizer applicator. During the application process, the flow rate can be adjusted according to the actual situation. After the application is completed, the power supply of the electric sprayer 2 is turned off, and the electric sprayer 2 is cleaned in time. The structure is simple, the cost is low, and it is easy to operate, which can overcome the problem that it is difficult to apply fertilizers and pesticides due to small irrigation area, insufficient pressure difference or viscous drugs, etc.

[0037] Further, as Figure 1 shown, it further includes a delivery pump 3. One end of the delivery pump 3 is communicated with the liquid outlet of the liquid storage tank 1, and the other end of the delivery pump 3 is communicated with the inlet end of the electric sprayer 2. The delivery pump 3 can quickly transport the liquid in the liquid storage tank 1 to the electric sprayer 2, realizing mechanized operation, saving time and effort.

[0038] Further, as Figure 1 shown, it further includes a regulating valve 4. One end of the regulating valve 4 is communicated with the outlet end of the electric sprayer 2, and the other end of the regulating valve 4 is communicated with the reserved access port 18. The connection between the regulating valve 4 and the reserved access port 18 is detachable. The regulating valve 4 can not only play the role of connecting the electric sprayer 2 and the reserved access port 18, but also adjust the outlet flow rate of the electric sprayer 2 by using the regulating valve 4 to ensure that the liquid is evenly sprayed into the drip irrigation pipe 17.

[0039] Further, as Figure 2As shown, the liquid storage tank 1 is a transparent tank, and there is a liquid level scale line 5 on the outer wall of the liquid storage tank 1, which is convenient for observing the liquid level change in the liquid storage tank 1.

[0040] Furthermore, as Figure 1 and Figure 2 shown, it further includes a moving seat 6. The liquid storage tank 1 and the electric sprayer 2 are both arranged on the moving seat 6. The electric sprayer 2 is located in front of the liquid storage tank 1. The moving seat 6 plays a role in supporting and positioning the liquid storage tank 1 and the electric sprayer 2, facilitating movement in the field, improving the convenience of operation, and saving time and effort. When there is a delivery pump 3, the delivery pump 3 is also arranged on the moving seat 6.

[0041] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, it further includes a first limiting rod 7 and a first elastic sleeve 8. The first limiting rod 7 is arranged on the moving seat 6 and is located outside the liquid storage tank 1. The number of the first limiting rods 7 is at least three, and all the first limiting rods 7 are arranged around the liquid storage tank 1; the first elastic sleeve 8 is sleeved outside the first limiting rod 7 and is used to contact the outer wall of the liquid storage tank 1. The first limiting rod 7 and the first elastic sleeve 8 cooperate to surround the liquid storage tank 1 in the middle, which can play a role in fixing and supporting the liquid storage tank 1, ensuring the stability and safety of the liquid storage tank 1, and preventing the liquid storage tank 1 from shaking and tipping over. The first elastic sleeve 8 has a certain elasticity, which can avoid the liquid storage tank 1 from being knocked and damaged. The four first limiting rods 7 in the front, rear, left, and right are evenly arranged outside the liquid storage tank 1. On the premise of ensuring that the liquid storage tank 1 is reliably limited, the number of the first limiting rods 7 and the first elastic sleeve 8 is reduced as much as possible, which can save costs.

[0042] Furthermore, as Figure 1 、 Figure 2 and Figure 4 shown, the upper surface of the moving seat 6 has a first positioning groove 9, and the lower end of the first limiting rod 7 is threadedly connected to the first positioning groove 9. When it is necessary to unload the liquid storage tank 1 from the moving seat 6, only need to disassemble the first limiting rod 7 on the left or right from the moving seat 6. After the liquid storage tank 1 is placed on the moving seat 6, then install the first limiting rod 7 onto the moving seat 6. The connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort.

[0043] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 ​As shown in the figure, it further includes a second limiting rod 10 and a second elastic sleeve 11. The second limiting rod 10 is arranged on the moving seat 6. The number of the second limiting rods 10 is multiple, and all the second limiting rods 10 are arranged around the electric sprayer 2. The second elastic sleeve 11 is sleeved on the periphery of the second limiting rod 10 and is used to contact the outer wall of the electric sprayer 2. The cooperation of the second limiting rod 10 and the second elastic sleeve 11 surrounds the electric sprayer 2 in the middle, which can play a role in fixing and supporting the electric sprayer 2, ensure the stability and safety of the electric sprayer 2, and prevent the electric sprayer 2 from shaking and tipping over. The second elastic sleeve 11 has a certain elasticity, which can avoid the electric sprayer 2 from being damaged by knocking. The first limiting rod 7 located between the liquid storage tank 1 and the electric sprayer 2 can support both the liquid storage tank 1 and the electric sprayer 2 at the same time, so that the number of the second limiting rods 10 and the second elastic sleeves 11 can be reduced, and the cost can be saved.

[0044] Further, as shown in Figure 1 , Figure 2 and Figure 5 the upper surface of the moving seat 6 has a second positioning groove 12, and the lower end of the second limiting rod 10 is threadedly connected to the second positioning groove 12. When it is necessary to unload the electric sprayer 2 from the moving seat 6, only the second limiting rod 10 on one side of the electric sprayer 2 needs to be disassembled from the moving seat 6. After the electric sprayer 2 is placed on the moving seat 6, the second limiting rod 10 on this side can be installed on the moving seat 6 again. The connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort.

[0045] Further, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 6As shown in the figure, the upper surface of the movable seat 6 has a limiting groove 13, and further includes a push-pull armrest 14 and an elastic snap ring 15.

The rear end of the elastic snap ring 15 is connected to the push-pull armrest 14. The front end of the elastic snap ring 15 has a notch 16. The upper end of the first limiting rod 7 or the second limiting rod 10 passes through the notch 16 and is used for clamping with the elastic snap ring 15, and the lower end of the first limiting rod 7 or the second limiting rod 10 is used for inserting into the limiting groove 13. The operator can push and pull the movable seat 6 by holding the push-pull armrest 14, which is convenient for movement. The number of elastic snap rings 15 is equal to the sum of the numbers of the first limiting rod 7 and the second limiting rod 10. All the elastic snap rings 15 are arranged in the left-right direction on the push-pull armrest 14. There is a limiting groove 13 at the position corresponding to each elastic snap ring 15 on the upper surface of the movable seat 6. When the first limiting rod 7 and the second limiting rod 10 are not in use, they can be disassembled. After the upper end passes through the notch 16, it is clamped with the elastic snap ring 15, and the lower end is inserted into the limiting groove 13 on the upper surface of the movable seat 6.
