Description

Technical Field

[0001] The utility model relates to the field of agricultural planting devices, in particular to a foam generator for weed control. Background Art

[0002] During the growth process of crops, weeds will grow near the roots and stems. Weeds will compete for the nutrients and sunlight in the soil near the roots and stems of crops, affecting the growth of crops. Seriously, it will cause the crops to lack nutrients and die, so weeds need to be removed. To remove weeds, herbicides need to be sprayed to make the weeds wither quickly. In the prior art, commonly used methods such as spraying with drones and manual spraying are used to spray the prepared herbicides. Essentially, this method is to spray the herbicides from top to bottom in a wide area by high-altitude spraying. Although the spraying speed is fast and it can quickly complete the spraying of large areas of crops, generally, the growth of weeds will be later than that of crops, and the height of crops will be much higher than that of weeds. Most of the herbicides sprayed from high altitude will fall on the leaves of crops and be absorbed through the respiration of the leaves. While it has a certain impact on the growth of crops, the amount of herbicides that can be sprayed on weeds is limited, wasting a large amount of herbicides.

[0003] Providing a method that can limit the spraying height of herbicides by using drip irrigation tapes, reduce the amount of herbicides sprayed on the leaves of crops, improve the coverage area of herbicides on weeds, and accelerate the withering of weeds, and the beneficial effect of reducing herbicide consumption can be foreseen. Summary of the Utility Model

Specific implementation manner

[0025] This application includes a water delivery pipe 1 for transporting water flow or foaming agent, which is the same as the prior art. A plurality of nozzles 2 are arranged at equal intervals along the axial direction on the water delivery pipe 1. The axis of the nozzle 2 is perpendicular to the axis of the water delivery pipe 1 and ensures that the nozzle of the nozzle 2 faces away from the ground. The water delivery pipe 1 is placed near the roots of the crops, so as to ensure that the water flow or foaming agent flowing in the water delivery pipe 1 can be sprayed near the roots of the plants. When it is necessary to spray herbicides to kill weeds near the crops, since the growth time of the crops is longer than that of the weeds and the overall height of the crops is higher than that of the weeds, the water delivery pipe 1 can be used to transport a mixture of herbicides and foaming agents and the nozzle 2 can be used for spraying so that the agent can be sprayed on the surface of the weeds near the roots of the crops. Compared with the traditional high-altitude spraying, such as spraying herbicides by drones or manually, the maximum height of the agent sprayed in this way is limited, and only a small part of the agent is sprayed on the leaves of the crops, reducing the absorption of the agent by the crop leaves during the breathing process, thereby reducing the impact of the herbicide on the growth of the crops. Compared with simply spraying herbicides, spraying a mixture of herbicides and foaming agents to form foam, so that the foam covers the surface of the weeds can increase the adhesion time of the agent to the weeds, extend the evaporation time of the agent and reduce the absorption of sunlight and air by the weeds through the covering method, isolating the sunlight and oxygen required for the growth of the weeds, thereby accelerating the death of the weeds.

[0026] In order to enable the mixed agent of herbicide and foaming agent sprayed from the nozzle 2 to turn into foam during the spraying process, a sleeve such as Figure 3The shown foaming assembly, the foaming assembly includes a sleeve 3 sleeved on the nozzle 2. The axis line of the nozzle 2 and the axis line of the sleeve 3 are collinearly arranged. The center of the sleeve 3 is designed with a hollow, enabling the entire foaming device to be fixed on the nozzle 2. An air inlet part 31 is detachably connected to the sleeve 3. The top end of the sleeve 3 is provided with an internal thread, and one end of the air inlet part 31 in contact with the sleeve 3 is provided with an external thread. The sleeve 3 and the air inlet part 31 are locked through the internal and external threads. An air inlet net 311 for absorbing air into the interior of the foaming assembly is arranged on the air inlet part 31. The air inlet net 311 is annularly arranged with a hollow center, and its axis line is collinearly arranged with the axis line of the air inlet part 31. A plurality of air inlet holes facilitating the inflow of air are arranged on the surface of the air inlet net 311. The mixed liquid medicine sprayed by the nozzle 2 is mixed with the air absorbed in the air inlet part 31 during the spraying process, so that the foaming agent and the air are mixed in a certain proportion and flow into the foaming part 32 installed on the air inlet part 31. A foaming plate 321 is arranged on the inner wall of the foaming part 32. A plurality of through holes are arranged on the foaming plate 321. After the liquid medicine and the air are mixed, they impact on the foaming plate 321 and pass through the plurality of through holes on the foaming plate 321 to generate foam, thereby ensuring that the herbicide sprayed from the foaming assembly is in a foam shape. As Figure 3 shown, the foaming part 32 installed on the air inlet part 31 is one or more. A plurality of foaming parts 32 are locked through the cooperation of internal and external threads, and the through holes arranged on each foaming plate 321 are arranged in a staggered manner, so that the foam generated by the foaming agent is more uniform and the foam generation amount is increased. The topmost foaming part 32 is installed with such as Figure 5 shown pressure increasing part 33. The pressure increasing part 33 is connected to the foaming part 32 through internal and external threads. Its interior is hollowly arranged and the diameters of the upper and lower ends are different, so that the internal pressure is increased, thereby increasing the flow rate of the foam. A spraying part 34 is installed on the pressure increasing part 33. A spraying part 35 is arranged on the spraying part 34. The spraying part 34 is used for spraying the pressurized foam. The spraying part 35 arranged at its top end is conical, and the smaller diameter end faces the spraying part 34. The pressurized and sprayed foam impacts on the spraying part 35, enabling the foam to move along the surface of the spraying part 35 and fly out, thereby ensuring the foam spraying area while increasing the flying distance of the foam, so that the foam sprayed by the device can better cover the surface of the weeds.

[0027] As Figure 5 shown, the mixed medicament is sprayed out through the nozzle 2 and moves axially along the interior of the nozzle 2, passes through the air inlet part 31 and flows into the foaming part 32, and impacts on the foaming plate 321 to generate an appropriate amount of foam. The generated foam passes through one or more foaming plates 321 and then flows into the pressure increasing part 33. The flow rate of the foam is increased by using the increase in the internal pressure of the pressure increasing part 33. Finally, the foam is sprayed out through the spraying part 34 and impacts on the spraying part 35.

[0028] To ensure the firmness of the connection between the foaming assembly and the nozzle 2, as Figure 2As shown, at both ends of the spray head 2, there are symmetrically arranged clamping blocks 21 for positioning. At one end of the sleeve 3 close to the clamping blocks 21, there are symmetrically arranged clamping plates 36. Through the cooperation of the clamping blocks 21 and the clamping plates 36, the sleeve 3 will not move in the same direction due to the spraying of the medicament, ensuring the firmness of its connection. Further, at the bottom end of the clamping block 21, there is a clamping groove 22. At one end of the clamping plate 36 that fits with the clamping block 21, there is a positioning ball 37. The positioning ball 37 is made of an elastic material, commonly rubber. The fitting of the positioning ball 37 with the clamping groove 22 ensures that the clamping plate 36 will not rotate radially during the operation of the device, thereby ensuring the firmness of the connection between the foaming assembly and the spray head 2.
