[0001] This utility model belongs to the field of agricultural sprayer technology, specifically relating to a portable multi-nozzle pest and disease sprayer. Background Technology

[0002] In agricultural planting operations, people need to regularly spray pesticides on crops to kill pests and ensure normal crop growth. Traditional agricultural spraying equipment is mostly manual sprayers, which people carry on their backs, holding the nozzle with one hand and manually pumping the pesticide with the other. To reduce the amount of labor, existing sprayers have been converted from manual to electric. The main difference is that a battery drives a water pump unit to pump the pesticide, thus eliminating the need for manual pumping.

[0003] Existing electric sprayers often lack a wide range of spray head adjustments, resulting in limited spray coverage during pesticide application. To address this, we have developed a portable multi-nozzle pest and disease sprayer based on existing electric sprayers. Utility Model Content

Detailed Implementation

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Example 1: like Figures 1 to 3 The portable multi-nozzle pest sprayer shown includes an electric sprayer body 1 and a spray bar 2. The electric sprayer body 1 includes a liquid storage chamber 11 and electrical equipment integrated into the bottom of the liquid storage chamber 11. The electrical equipment includes, but is not limited to, a power switch, a charging socket, a battery, and a water pump unit. The output end of the electric sprayer body 1 is provided with a flow regulating mechanism 12, which is connected to a handle 13. The handle 13 is equipped with a push-button switch 131. The spray bar 2 is connected to the handle 13, and a spraying mechanism is installed at the end of the spray bar 2. The liquid storage chamber 11 is used to store pesticides. This is a standard existing device. Compared to traditional manual sprayers, it uses a battery to power the water pump unit, enabling the water pump unit to pump out pesticides. The integrated power switch is used for the overall power switch of the electric sprayer body 1, the charging socket is used for charging the battery, and the push switch 131 on the handle 13 is used to turn the water pump unit on or off. When in use, by holding the handle 13, the spray bar 2 can be pointed at the crop to be sprayed. By pressing the switch 131, the pesticide can be pumped out to spray the crop. The flow adjustment mechanism 12 is used to adjust the flow rate of the sprayed pesticides.

[0016] The spraying mechanism includes: Connecting seat 21, the connecting seat 21 is installed and fixed to the end of the spray bar 2; A main nozzle 22 is installed coaxially with the spray bar 2; Several branch nozzles 23, each branch nozzle 23 is a gooseneck tube, and each branch nozzle 23 is installed on the side of the connector 21 and is distributed in a circumferential array. The main nozzle 22 and each branch nozzle 23 are equipped with a connector 24, which is used to install a DC nozzle 241 or a diffuser nozzle 242. The main nozzle 22 and each branch nozzle 23 are equipped with a switching valve 25.

[0017] Currently, sprayers generally have a small spray head range, which cannot achieve large-area spraying operations. Therefore, this application designs the above-mentioned spraying mechanism. Specifically, since the main spray pipe 22 is installed coaxially with the spray bar 2, the main spray pipe 22 can spray towards the axis of the spray bar 2. At the same time, each branch spray pipe 23 adopts a gooseneck tube, so that each branch spray pipe 23 can be manually pulled to adjust in the desired direction. If a large-area spraying operation is required, each branch spray pipe 23 can be adjusted by moving it. Meanwhile, connectors 24 are provided on the main nozzle 22 and the branch nozzle 23 so that the required DC nozzle 241 or diffuser nozzle 242 can be installed through the connectors 24 according to the operation requirements. Switch valves 25 are provided on the main nozzle 22 and the branch nozzle 23. If only a small-scale spraying operation is required, the switch valve 25 of the branch nozzle 23 can be closed, and the spraying operation can be carried out through the main nozzle 22 alone.

[0018] This invention redesigns the spraying mechanism of existing electric sprayers, which can be adjusted as needed to expand the spraying range and is practical.

[0019] As a structural description of the flow regulation mechanism 12 in this embodiment, as follows: Figure 1 and Figure 3 As shown, the flow regulating mechanism 12 includes: T-shaped tee pipe 121, one end of the lateral side of the T-shaped tee pipe 121 is connected to the output end of the electric sprayer body 1; Hose 122, one end of hose 122 is connected to the other end of the lateral side of T-shaped tee 121, and the other end of hose 122 is connected to handle 13; The plugging head 123 is movably disposed inside the longitudinal side of the T-shaped tee pipe 121; Adjusting component 124 is installed on the longitudinal side of T-shaped tee pipe 121. Adjusting component 124 is used to drive the sealing head 123 to move inside the longitudinal side of T-shaped tee pipe 121. Adjusting component 124 includes adjusting screw 1241 and adjusting knob 1242. The inner wall of the longitudinal side end of T-shaped tee pipe 121 is threaded. Adjusting screw 1241 is threadedly connected to the longitudinal side of T-shaped tee pipe 121. One end of adjusting screw 1241 is fixedly connected to sealing head 123 and the other end is fixedly connected to adjusting knob 1242.

[0020] like Figure 3As shown, this is the state when the plugging head 123 completely blocks the T-shaped tee pipe 121. When the flow regulating mechanism 12 is used, by rotating the regulating knob 1242, since the regulating knob 1242 is threadedly connected to the longitudinal side of the T-shaped tee pipe 121, rotating the regulating knob 1242 will cause the regulating screw 1241 to gradually extend from the longitudinal side of the T-shaped tee pipe 121, thereby causing the plugging head 123 to gradually retract from the lateral side of the T-shaped tee pipe 121 to the longitudinal side, so as to change the flow surface of the pesticide on the lateral side of the T-shaped tee pipe 121, thereby effectively controlling the flow rate of the pesticide pumped to the spray bar 2. The flexible hose 122 allows for the connection of the spray bar 2 to be movable, enabling the spray bar 2 to be moved by the user's hand.

[0021] Meanwhile, to ensure the sealing of the longitudinal side of the T-shaped tee 121, the following design is made, such as... Figure 3 As shown, a sealing ring 1243 is also provided on one side of the adjusting screw 1241 inside the T-shaped tee tube 121; the sealing ring 1243 can seal the longitudinal inner wall of the T-shaped tee tube 121, thereby preventing pesticides from leaking out from the longitudinal side of the T-shaped tee tube 121.

[0022] As a further structural description of the main body 1 of the electric sprayer, such as Figure 1 As shown, the electric sprayer body 1 is also equipped with shoulder straps 3 on both sides. The shoulder straps 3 are adjusted by using D-ring buckles 31. People can carry the sprayer on their backs by using the shoulder straps 3. The D-ring buckles 31 can effectively adjust the tightness so that the shoulder straps 3 will not slip off the back.

[0023] Example 2: This embodiment is a further improvement on Embodiment 1, with the aim of minimizing vibration when the sprayer is carried and used. Figure 4 As shown, the surface of the electric sprayer body 1 is also provided with a back plate 4. The back plate 4 is provided with first transverse support rods 41 on both the upper and lower sides. An elastic net 42 is bonded between the first transverse support rods 41 on both sides. Multiple second transverse support rods 43 are also bonded to the middle of the elastic net 42. The back plate 4 and each of the second transverse support rods 43 are elastically connected by multiple spring pieces 44.

[0024] After the person carries the sprayer on their back using the shoulder strap 3 and adjusts the tightness using the D-ring buckle 31, the back of the person can be placed against the elastic net 42 between the two first horizontal support rods 41. Through the elastic force of multiple spring pieces 44, each second horizontal support rod 43 causes the middle part of the elastic net 42 to bulge, so that the elastic net 42 can elastically fit the back of the person. In this way, the shoulder strap 3 and the elastic net 42 together achieve the fixation of the sprayer on the person, which can ensure the stability of the sprayer during the use of the person carrying it without significant vibration. Furthermore, the elastic mesh 42 has a mesh structure, which can dissipate heat and ventilate without accumulating sweat when in contact with the human body.

[0025] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
