Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a liquid medicine negative pressure recovery device, liquid medicine equipment for experiments, and liquid medicine equipment for field use. Background Art

[0002] With the development of modern agriculture, the application of pesticides has become one of the important means of preventing and controlling crop diseases and pests. However, the irrational use of pesticides will not only lead to waste of resources, but also have a serious negative impact on the ecological environment. In order to promote sustainable agricultural development and reduce the impact of chemical pesticides on the environment, countries are actively developing new environmentally friendly pesticides and application technologies, striving to improve the utilization rate of pesticides and reduce pollution to the environment.

[0003] At present, in the cotton planting process, seedling spraying is a common pest control measure. However, traditional spraying equipment mainly relies on high-pressure nozzles to atomize the liquid medicine and spray it directly on the crops. Although this method is easy to operate, it has many shortcomings in practical applications. On the one hand, the particle size of the liquid medicine droplets is difficult to control, resulting in some liquid medicine failing to effectively adhere to the target plants; on the other hand, the spraying process is easily affected by natural factors such as wind speed and wind direction, resulting in a large amount of liquid medicine failing to reach the expected coverage area.

[0004] Due to the influence of wind and other factors during the spraying process, the liquid medicine drifts seriously, which not only causes a great waste of pesticide resources, but also the undeposited liquid medicine drifts into the air or falls into the soil, which may cause air and soil pollution. In addition, the drifted liquid medicine may also cause pesticide damage to surrounding non-target crops, thereby reducing the safety and economic benefits of agricultural production. Therefore, how to effectively recover the undeposited liquid medicine has become a technical problem that needs to be solved urgently. Summary of the invention

[0065] Embodiment 1

[0066] like Figure 1As shown, embodiment 1 of the first aspect of the present disclosure provides a liquid medicine negative pressure recovery device, comprising: a recovery component 1 and a drainage component 2; a recovery space A is arranged inside the recovery component 1, and the recovery space A is under negative pressure conditions; the drainage component 2 is connected to one side of the recovery component 1 in the horizontal direction, and the drainage component 2 is provided with a first drainage structure and a second drainage structure in sequence in a vertical downward direction, and the drainage effect of the first drainage structure is weaker than the drainage effect of the second drainage structure; wherein the recovery space A recovers the external liquid medicine through the first drainage structure and the second drainage structure.

[0067] Specifically, the recycling component 1 can be a recycling box or a recycling cylinder, which is not specifically limited, and the internal space of the recycling box or the recycling cylinder can be used as the recycling space A. The negative pressure condition inside the recycling space A can be that an exhaust fan and an exhaust port are set in the recycling space A, and the air inside the recycling space A is exhausted through the cooperation of the two to form a negative pressure condition, and its specific form is not limited.

[0068] The drainage component 2 can be a cover installed on the recovery component 1. The recovery component 1 can be provided with a mounting hole connected to the recovery space A, and the drainage component 2 is snapped on the mounting hole. The first drainage structure and the second drainage structure can be two groups of holes arranged on the drainage component 2. The first drainage structure is above the second drainage structure in the vertical direction to achieve the connection between the recovery space A and the external environment. The drainage effect can specifically be the flow rate introduced into the recovery space A. When the first drainage structure and the second drainage structure recycle the external medicine liquid, the drifting medicine liquid droplets will flow into the recovery space A along with the circulation of air flow. The second drainage structure can introduce more air flow into the recovery space A compared with the first drainage structure. Specifically, the drainage effect of the first drainage structure can be weaker than the drainage effect of the second drainage structure by setting the difference in the aperture size in the two hole groups.

[0069] The first aspect of the present application provides a negative pressure recovery device for liquid medicine, comprising: a recovery component 1 and a drainage component 2, wherein the recovery component 1 has a recovery space A in a negative pressure state inside, the drainage component 2 is connected to the recovery component 1 in a horizontal direction, and the drainage component 2 is provided with a first drainage structure and a second drainage structure, the first drainage structure and the second drainage structure are arranged in sequence in a vertical downward direction, and the drainage effect of the first drainage structure is weaker than the drainage effect of the second drainage structure.

[0070] During the working process, the growth direction of the cotton seedlings is generally vertical. The negative pressure recovery device for the liquid medicine is arranged on one side of the horizontal direction of the cotton seedlings, and the first drainage structure and the second drainage structure are facing the cotton seedlings. At the same time, the projections of the first drainage structure and the second drainage structure onto the cotton seedlings cover the entire cotton seedlings. The spraying device 5 is located above the cotton seedlings, and sprays the liquid medicine from top to bottom. Since the recovery space A is in a negative pressure condition, the liquid medicine droplets that are sprayed and not covered on the cotton seedlings are recovered by the recovery component 1 along with the space to the recovery space A, so as to realize the recovery of the liquid medicine that has drifted, and effectively reduce the waste caused by the drift of the liquid medicine.

[0071] Since the drainage effect of the first drainage structure is weaker than that of the second drainage structure, less medicine is recovered at the top of the cotton seedling corresponding to the first drainage structure after the medicine is sprayed out. While recovering the drifted medicine, more medicine can be attached to the leaves of the cotton seedlings, while the neck of the cotton seedling corresponding to the second drainage structure does not need to be attached with more medicine. Therefore, the better drainage effect of the second drainage structure can recover more drifted medicine, so as to reduce the air and soil pollution problems caused by the undeposited medicine drifting into the air or falling into the soil.

[0072] like Figure 2 As shown, in some embodiments, the drainage component 2 includes: a first frame 21, a plurality of first fan blades 22 and a plurality of second fan blades 23; the first frame 21 is connected to the recovery component 1, and the interior of the first frame 21 is provided with a first area and a second area which are arranged adjacent to each other in sequence along the vertical downward direction; the plurality of first fan blades 22 are arranged in the first area along the vertical direction to form a first drainage structure; the plurality of second fan blades 23 are arranged in the second area along the vertical direction to form a second drainage structure; wherein the opening of the plurality of first fan blades 22 is smaller than the opening of the plurality of second fan blades 23.

[0073] Specifically, the first frame 21 can be a circular frame. In the present embodiment, the first frame 21 can adopt a rectangular frame. The connection relationship between the rectangular frame and the recovery component 1 can be connected by rivets or bolts, and is not specifically limited. The internal area of ​​the first frame 21 is divided into a first area and a second area, and the first area is above the second area. The first blade 22 and the second blade 23 are not specifically limited, and it can be ensured that the first blade 22 makes the air flow through the first area less than the air flow through the second area by the second blade 23. In the present embodiment, the first blade 22 and the second blade 23 can be the same blade, so that the opening of the first blade 22 is less than the second blade 23, which can control the air flow through the first area to be less than the air flow through the second area. The connection relationship between the multiple first blades 22 and the multiple second blades 23 and the first frame 21 can be through welding, or it can be clamped by a slot, and its connection method is not specifically limited.

[0074] like Figure 3 As shown, in some embodiments, the recovery component 1 includes: a second frame 11 and a baffle demister 12; the internal area of ​​the second frame 11 constitutes a recovery space A, and the drainage component 2 is connected to the second frame 11; the baffle demister 12 is arranged inside the second frame 11.

[0075] Specifically, the second frame 11 can be a circular frame or a rectangular frame, and is not specifically limited. The inner frame portion of the second frame 11 has a depth in the horizontal direction to enclose a first channel structure, and the first channel structure can be used as a recovery space A. The connection method between the drainage component 2 and the second frame 11 can be that the second frame 11 and the first frame 21 are connected in the horizontal direction by welding or rivet connection, and the inner frame area of ​​the first frame 21 is corresponding to the inner frame area of ​​the second frame 11, so that the air flow can enter the inner frame area of ​​the second frame 11 through the first drainage structure and the second drainage structure, that is, the recovery space A.

[0076] The baffle demister 12 may be a baffle demister 12 of the prior art standard, and a plurality of baffles stacked in the vertical direction are arranged inside the baffle demister 12. In this embodiment, the baffle may be an S-shaped baffle, and the groove in the middle of the S-shaped baffle is vertically downward, so that after the baffle demister 12 separates the air flow and the liquid medicine, the liquid medicine on the baffle can move vertically downward and finally flow to the bottom of the recovery space A. The connection relationship between the baffle demister 12 and the second frame 11 may be connected by bolts or rivets.

[0077] like Figure 4 As shown, in some embodiments, the recovery component 1 also includes: a third frame 13 and a droplet deposition net 14; the third frame 13 is arranged to be connected to the side of the second frame 11 away from the drainage component 2, and the interior of the second frame 11 and the interior of the third frame 13 together constitute a recovery space A; the droplet deposition net 14 is arranged inside the third frame 13.

[0078] Specifically, the third frame 13 can be a circular frame or a rectangular frame, which is not specifically limited. The inner frame portion of the third frame 13 also has a depth in the horizontal direction to enclose a second channel. When the second frame 11 is connected to the third frame 13, the first channel structure is connected to the second channel structure to form a recovery space A together. The connection between the third frame 13 and the second frame 11 can be welding or rivet connection, which is not specifically limited. The connection between the droplet deposition net 14 and the third frame 13 can be rivet connection or fixed by a connecting groove. The droplet deposition net 14 can adopt a standard droplet deposition net 14, which is not specifically limited. The droplet deposition net 14 is a porous medium layer, and the liquid droplets of the liquid medicine form a spray in the air flow. The porous medium layer can effectively prevent the spray from flowing back and increase the recovery rate of the liquid medicine.

[0079] like Figure 1 As shown, in some embodiments, the recovery component 1 also includes: a pipe connector 15, the pipe connector 15 is provided with a pipe connection hole 151, the pipe connection hole 151 is used to connect the negative pressure device 6, the pipe connector 15 is arranged on the side of the third frame 13 away from the second frame 11, and the pipe connector 15, the second frame 11 and the third frame 13 enclose a recovery space A.

[0080] The pipe connector 15 has a cover body with a pipe connection hole 151, which is connected to the side of the third frame 13 away from the second frame 11. The connection relationship between the two can be connected by bolts or by welding, and the connection method is not limited. In this embodiment, the pipe connector 15 can be a cover body with a closing structure, and the closing structure is provided with a pipe connection hole 151. The pipe connector 15, the second frame 11 and the third frame 13 enclose a recovery space A. The recovery space A is connected to the negative pressure device 6 through the pipe connected to the pipe connection hole 151, and a negative pressure condition is formed inside the recovery space A through the negative pressure device 6. It should be noted that during the connection process between the first frame 21, the second frame 11, the third frame 13 and the pipe connector 15, it is necessary to ensure that the connection is sealed. Specifically, a seal can be provided between the interconnected components to ensure the sealing of the recovery space A.

[0081] like Figure 2 As shown, in some embodiments, a first gear structure 24 is fixedly provided at both ends of the first fan blade 22 in the length direction, the first fan blade 22 is rotatably connected to the first frame 21, and the first gear structures 24 of two adjacent first fan blades 22 are meshed with each other; a second gear structure 25 is fixedly provided at both ends of the second fan blade 23 in the length direction, the second fan blade 23 is rotatably connected to the first frame 21, and the second gear structures 25 of two adjacent second fan blades 23 are meshed with each other.

[0082] Specifically, the rotational connection between the plurality of first blades 22 and the plurality of second blades 23 and the first frame 21 can be realized by bearings or by clearance fit, and is not specifically limited. Two first gear structures 24 are respectively provided at both ends of the length direction of the first blade 22, and are fixedly connected with the first gear structure 24, and the fixed connection method can be by welding or by slot connection. The first gear structures 24 provided at the first ends of the two adjacent first blades 22 fit each other, and the first gear structures 24 provided at the first ends of the two adjacent second blades 23 fit each other to realize that when a first blade 22 is driven to rotate relative to the first frame 21, the remaining first blades 22 can be driven to realize that the plurality of first blades 22 rotate synchronously. The two second gear structures 25 provided at both ends of the length direction of the second blade 23 are the same as the connection method and motion principle of the first blade 22 and the first gear structure 24, and are not repeated here. Driving a second blade 23 to rotate can also drive other second blades 23 to rotate synchronously. Such an arrangement can adjust the opening of the first blade 22 and the second blade 23 according to the external air flow rate, thereby increasing the recovery rate of the liquid medicine, and at the same time, it is more convenient to adjust multiple first blades 22 and multiple second blades 23.

[0083] like Figure 1 As shown, in some embodiments, a drain port 16 is provided at the bottom of the recovery component 1 along the vertical direction; the liquid medicine negative pressure recovery device also includes a guide plate 3, which is provided below the recovery component 1 and connected to the recovery component 1, and the guide plate 3 extends in a direction away from the recovery component 1 and extends to the side of the drainage component 2 away from the recovery component 1.

[0084] Specifically, the guide plate 3 can be a long rectangular plate or a long elliptical plate, which is not specifically limited. In the present embodiment, a rectangular plate can be used as the guide plate 3, and one end of the guide plate 3 in the width direction is connected to the recovery component 1, and the connection method can be through rivets or welding, which is not specifically limited. The other end of the guide plate 3 extends in the direction away from the recovery component 1, and extends to the side of the drainage component 2 away from the recovery component 1, so that the guide plate 3 extends to the side of the drainage component 2 away from the recovery component 1, and has an acute angle of inclination with the horizontal direction. The guide plate 3 can prevent the liquid medicine that is not recovered by the recovery component 1 from being blocked, and can reduce the liquid medicine from falling to the soil surface due to gravity and contaminating the soil. The liquid medicine attached to the guide plate 3 will slide to a lower place due to the inclination of the guide plate 3. For the drainage port 16 set at the bottom of the recovery component 1 in the vertical direction, the liquid medicine recovered in the recovery space A can be released into the guide plate 3 for the same recovery. In this embodiment, a timing device may be provided to open the liquid discharge port 16 periodically to prevent excessive accumulation of liquid medicine in the recovery space A.

[0086] Specifically, the medicine liquid recovered by the guide plate 3 can be directly transmitted to the medicine liquid tank 51 through the pipe connected to the recovery port 31, so that the recovered medicine liquid can be reused. Similarly, the bottom of the recovery component 1 can also be inclined to facilitate the discharge of the medicine liquid from the drain port 16 to the recovery port 31.
