Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically an agricultural pesticide spraying device. Background Technology

[0002] Backpack sprayers (pesticide applicators) are one of the most commonly used pesticide spraying devices in agricultural production. They are mostly used in mountainous areas or greenhouse agriculture where mechanized spraying is difficult.

[0003] Most backpack sprayers are currently manual, mainly divided into liquid pump type and air pump type. However, they all require users to press the crank up and down to pump out pesticides, which is quite laborious. According to the search, the patent with announcement number CN220422859U discloses a high-lift backpack sprayer and fertilizer applicator. It uses a controller, screen and buttons to control the water pump power. The higher the power, the higher the spraying height. The spraying is controlled by a switch on the handle. The device replaces manual cranking with water pump operation, reducing the burden on workers. At the same time, the device is backpack-type, which is more compact and can be used for fertilization in areas with more complex environmental conditions.

[0004] The above solution eliminates the need for users to manually pump out pesticides by using water pumps, but it only has a few back pads on the back of the box. While this can improve carrying comfort to some extent, pesticide spraying is mostly done in summer when the ambient temperature is high, and the device does not have the function of cooling down the user, which needs to be improved. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When using this invention, the pesticide to be sprayed is injected into the storage chamber through the injection port. The user then carries the box on their back using the shoulder strap, holds the spray gun, and starts the water pump via a switch. This pumps the pesticide from the storage chamber into the hose, which is then sprayed out by the spray gun. The operation is simple and convenient. In summer, the fan can be turned on to cool the user's back through the air-cooling mechanism, thus providing a cooling effect and improving user comfort. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, an agricultural pesticide spraying device includes a box 1 with an open bottom. A V-shaped partition 5 is fixedly installed on the inner wall of the box 1. A liquid storage chamber 6 is formed above the V-shaped partition 5 inside the box 1. An injection port communicating with the liquid storage chamber 6 is opened at the top of the box 1. An outlet is provided through the bottom of the V-shaped partition 5. A base 7 is fixedly installed at the bottom opening of the box 1. A water pump 8 is fixedly installed at the top of the base 7. The water inlet of the water pump 8 is connected to the outlet of the V-shaped partition 5 through a pipe. The water outlet of the water pump 8 is connected to a spray gun 10 through a flexible hose 9 penetrating the box 1. A battery 11 is fixedly installed at the top of the base 7. A switch 12 is installed on the outer wall of the box 1. A back box 17 and two shoulder straps 16 are fixedly installed on the front wall of the box 1. A wind-cooling mechanism is provided on the back box 17.

[0021] When using this utility model, the pesticide to be sprayed is injected into the storage chamber 6 through the injection port. Then, the box 1 is carried on the body using the shoulder strap 16. The spray gun 10 is held in hand, and the water pump 10 is started by the switch 12. The pesticide in the storage chamber 6 is then pumped into the hose 9 and sprayed out by the spray gun 10. The operation is simple and convenient. In summer, the air-cooling mechanism can cool the user's back to relieve heat and improve the comfort of use.

[0022] Specific combination Figure 3 and Figure 4 In one embodiment of this utility model, the bottom of the back box 17 is open, and the air-cooling mechanism includes several partitions 18 fixedly installed inside the back box 17. The partitions 18 divide the interior of the back box 17 into multiple air ducts 19. The bottom of the air duct 19 is an air inlet, and a fan 20 is fixedly installed on the inner wall of the bottom of the air duct 19. Multiple air outlets 21 are provided through the front wall of the back box 17 and the corresponding positions of each air duct 19. The air outlets 21 are connected to the corresponding air ducts 19.

[0023] By activating the fan 20, outside air can be blown into each air duct 19, and then blown towards the user's back through the corresponding air outlet 21, so as to achieve the effect of cooling down.

[0024] Specific combination Figure 3 and Figure 4 Furthermore, based on the previous embodiment, a plurality of soft blocks 22 are fixedly installed on the front wall of the back box 17. The soft blocks can be rubber blocks or silicone blocks.

[0025] By setting up the soft block 22, the front wall of the back box 17 can maintain a certain distance from the user's back, so as to avoid the air outlet 21 being in close contact with the user's back, thereby ensuring that the air in the air duct 19 can be smoothly discharged from each air outlet 21.

[0026] Specific combination Figure 2 In one embodiment of the present invention, a geared motor 14 is fixedly installed at the bottom of the V-shaped partition 5. The output shaft of the geared motor 14 passes through the liquid storage chamber 6 and is fixedly connected to a stirring blade 15. The output shaft of the geared motor 14 and the V-shaped partition 5 are mechanically sealed together.

[0027] By starting the geared motor 14, the stirring blade 15 can be used to stir the liquid in the storage chamber 6, thereby ensuring the uniformity of the drug solution mixing.

[0028] Specific combination Figure 2 In one embodiment of this utility model, the liquid injection port at the top of the box 1 is connected to a plug 2 by an external thread, the top of the plug 2 is provided with a through hole 3, and a filter screen 4 is provided inside the plug 2.

[0029] By using the plug 2 and filter 4, outside air can be allowed to enter the storage chamber 6 during the process of pumping the liquid medicine out of the storage chamber 6, so as to ensure the air pressure balance inside and outside the storage chamber 6. The filter 4 can reduce the amount of dust and impurities that enter the storage chamber 6 with the air.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
