[0001] The utility model relates to an air - blowing orchard pesticide spraying machine, belonging to the technical field of air - blown orchard pesticide spraying machines. Background Technique

[0002] With the gradual maturity of fruit tree planting technology in China, orchard pesticide spraying machines have become commonly used equipment in agricultural production, mainly used for pest control of fruit trees. During the process of orchard pesticide spraying, in order to improve the spraying effect and efficiency, it is usually necessary to use a blower to provide air flow to disperse the pesticide solution and evenly spray it onto the fruit trees. Therefore, the blower structure of the orchard pesticide spraying machine is of great significance for the spraying effect and efficiency.

[0003] Most of the air - blowing orchard pesticide spraying machines on the market now adopt the shape of a straight - tube axial - flow fan. Although the straight - tube axial - flow fan has the advantages of simple structure and convenient maintenance, the air volume of the straight - tube axial - flow fan is small, and it can only blow air in a straight line in a certain direction. Therefore, there is a problem of poor pesticide spraying effect in large orchards.

[0004] To sum up, it is obvious that there are inconveniences and defects in the prior art in actual use, so it is necessary to improve it. Content of the Utility Model

[0005] Aiming at the deficiencies in the background technique, the utility model provides an air - blowing orchard pesticide spraying machine, which can increase the range of air supply and pesticide spraying, and has a large air volume, and has a good spraying effect in large orchards.

[0026] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0027] As Figures 1 - 3 shown, the present utility model provides a blowing-type orchard pesticide spraying machine, which includes a front housing 1 and a rear housing 3. A blowing channel is formed between the front housing 1 and the rear housing 3. The fan system blows air into the blowing channel. A plurality of pesticide nozzles 8 are provided at the edge of the blowing channel. The air entering the blowing channel sprays out from its edge, thereby throwing the pesticide sprayed by the pesticide nozzles 8 outward.

[0028] The front housing 1 and the rear housing 3 are two parallel flat plates, which are arranged at intervals to form a blowing channel.

[0029] A front axial-flow fan 2 is provided on the outer side of the front housing 1. The air inlet of the front axial-flow fan 2 is communicated with the blowing channel, and the front axial-flow fan 2 blows air into the blowing channel.

[0030] In some other embodiments, a rear axial-flow fan 4 is provided on the outer side of the rear housing 3. The air inlet of the rear axial-flow fan 4 is communicated with the blowing channel, and the rear axial-flow fan 4 blows air into the blowing channel.

[0031] The front axial-flow fan 2 can be provided alone on the front housing 1 or the rear axial-flow fan 4 can be provided alone on the rear housing 3. It is also possible to provide the front axial-flow fan 2 and the rear axial-flow fan 4 respectively on the front housing 1 and the rear housing 3 at the same time.

[0032] When using a double-fan system, both the front axial-flow fan 2 and the rear axial-flow fan 4 are driven by a transmission shaft 7. The front axial-flow fan 2 is a forward fan, and the rear axial-flow fan 4 is a reverse fan. The fan blades of the forward fan 2 and the reverse fan 4 are in opposite states, so as to enable both fans to have a suction effect when driven by the same transmission shaft, solving the problem of small air volume to a certain extent. At the same time, the two fans are driven by the same transmission shaft, solving the problems of high noise and high energy consumption to a certain extent.

[0033] When using a double-fan system, an air flow baffle 5 is provided at the middle position between the front housing 1 and the rear housing 3. The air flow baffle 5 can evenly disperse the air flow entering from the fan to the surrounding, providing wind power for the pesticide nozzles 8, thereby achieving the effects of improving the spraying effect and the prevention and control efficiency.

[0034] A support connecting shaft 6 is provided between the front housing 1 and the rear housing 3. The support connecting shaft 6 connects the front housing 1, the rear housing 3, and the air flow baffle 5.

[0035] An upper sealing plate 10 is provided at the upper ends of the front housing 1 and the rear housing 3, and a lower sealing plate 9 is provided at the lower ends. The chemical agent spray nozzles 8 are arranged at the edges on both sides of the air supply channel.

[0036] When spraying pesticides, the front housing 1 or the rear housing 3 is mounted facing the tractor, and the traveling direction of the tractor is perpendicular to the front housing 1 and the rear housing 3, so that both sides of the air supply channel face both sides. The tractor drives the pesticide spraying machine to move forward, and sprays pesticides to both sides through the air supply channel. The range of air supply and pesticide spraying is large, and the pesticide spraying effect is good in a large orchard.

[0037] The above is an example of the best implementation mode of the present invention, and the parts not described in detail are all common general knowledge of those skilled in the art.
