Description

Technical Field

[0001] The utility model relates to a double-speed split-flow centrifugal sprayer. Background Art

[0002] The air-blown centrifugal sprayer is a spray system that uses wind to spray liquid into the air. This type of sprayer is often used in the agricultural field, such as spray irrigation of crops or spraying of pesticides. Its working principle is to use a fan to centrifugally spray liquid from the nozzle and atomize it into fine particles, which are then transported to the target area by wind.

[0003] Air-assisted sprayers usually consist of a sprayer, a liquid storage tank, a pump, and a control system. The liquid is pumped from the tank into the sprayer, then atomized through the nozzle and delivered to the target surface by the airflow generated by the fan. This type of sprayer is usually used for large-area spraying and can quickly cover a large area.

[0004] The existing air-conveying centrifugal sprayer usually has a driving motor installed at the bottom of the sprayer, and then the power is transmitted to the fan blades through the transmission belt system, so that the fan blades rotate. Since the transmission belt system needs to maintain high-speed rotation, the rotation speed of the fan blades is relatively high, the intermediate energy loss is relatively large, the energy consumption is large, and the high-speed rotation of the transmission belt system will cause the transmission belt to heat up and wear, thus affecting its service life. Utility Model Content

[0005] The utility model aims to provide a two-speed split-flow centrifugal sprayer, which can reduce energy loss and ensure a longer service life, and can also achieve two-speed blade speed change to expand the scope of use.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0021] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2As shown, a dual-speed split-flow centrifugal sprayer includes a bracket 1. The bracket 1 can be placed on a vehicle to facilitate the movement of the bracket 1. A liquid storage tank 2 is arranged on the bracket 1. The liquid storage tank 2 is filled with water or pesticide liquid. A water pump 3 is arranged on one side of the bottom of the liquid storage tank 2 of the bracket 1. One side of the water inlet of the water pump 3 is connected to the liquid storage tank 2 through a pipeline, and the other end is connected to a water pipe 4. The end of the water pipe 4 presents a semicircular-ring structure and is arranged on one side of the liquid storage tank 2.

[0024] The end of the water pipe 4 is provided with water outlets 5 arranged in a circumferential manner. When the water pump 3 is working, the liquid in the liquid storage tank 2 is extracted and output through the water outlet 5 of the water pipe 4. At this time, the direction in which the liquid is sprayed out of the water outlet 5 is horizontal.

[0025] Correspondingly, the bracket 1 is provided with a wind tube 6 on one side of the water outlet 5. A fan blade 7 is provided on one side of the wind tube 6. When the fan blade 7 rotates, the liquid sprayed horizontally is transformed into a vertical direction under the action of wind force, so that the atomized liquid is sprayed outward in a fan shape on one side of the wind tube 6 and the liquid storage tank 2, that is, Figure 1 The arrow shown is the direction of the spray.

[0026] The core technical solution of this application is as follows:

[0027] like Figure 3 , Figure 4 As shown, in order to solve the problem of wear of the transmission belt 16 system under high-speed rotation and realize the two-speed change of the fan blade 7, the present application replaces a new transmission system, which is as follows: a drive shaft 8 is provided at one end of the water pump 3. The drive shaft 8 is connected to a gear 1 9. The gear 1 9 is meshed with a gear 2 10.

[0028] Among them, the thickness of gear 2 10 is greater than that of gear 1 9. A rotating shaft 11 is fixedly penetrated in the middle of gear 2 10. A bearing seat 12 is arranged at the end of the rotating shaft 11. The bottom of the bearing seat 12 is slidably connected with a bottom plate 13. The bearing seat 12 can slide back and forth on the bottom plate 13, thereby driving gear 2 10 to slide back and forth. During the sliding process of gear 2 10, it always keeps meshing with gear 1 9.

[0029] A transmission wheel 14 is disposed at the end of the rotating shaft 11. A driving wheel 15 is disposed above the transmission wheel 14. A transmission belt 16 is disposed between the transmission wheel 14 and the driving wheel 15. When the rotating shaft 11 rotates, the transmission wheel 14 is driven to rotate, thereby driving the driving wheel 15 to rotate through the transmission belt 16.

[0030] An output shaft 17 is connected to the middle of the driving wheel 15. The output shaft 17 is connected to the same bearing seat 12 and bottom plate 13 as above. The bottom plate 13 is connected to the liquid storage tank 2. A fixed sleeve of a speed change wheel 19 and a speed change wheel 20 are provided on one side of the output shaft 17.

[0031] Among them, the speed change wheel 19 is meshed with the matching wheel 1 21 in the initial state. A matching wheel 2 22 is arranged on one side of the matching wheel 1 21. In the initial state, the matching wheel 2 22 and the speed change wheel 2 20 are mutually offset. The matching wheel 1 21 and the matching wheel 2 22 are connected to a rotating shaft 23. The rotating shaft 23 is fixedly connected to the fan blade 7.

[0032] Optimally, the size of the second mating wheel 22 is smaller than that of the second speed-changing wheel 20, so that when the second speed-changing wheel 20 rotates one circle, the second mating wheel 22 rotates multiple circles, so that the second mating wheel 22 can obtain a high rotation speed.

[0033] Overall working process:

[0034] 1. Place the whole centrifugal sprayer on the ground or on a vehicle, and then start the water pump 3;

[0035] 2. The water pump 3 works to output the liquid in the liquid storage tank 2 to the end of the water pipe 4. The water outlet 5 at the end of the water pipe 4 sprays the liquid;

[0036] 3. In this process, the drive shaft 8 drives the gear 1 9 to rotate, thereby driving the gear 2 10 to rotate, and then the rotating shaft 11 rotates at a constant speed; the rotating shaft 11 rotates and transmits power to the output shaft 17 through the transmission belt 16, so that the output shaft 17 rotates;

[0037] 4. The speed change wheel 19 at the end of the output shaft 17 meshes with the speed change wheel 20, thereby driving the rotating shaft 23 to rotate, so that the fan blades 7 rotate at a low speed. At this time, the fan blades 7 disperse and atomize the liquid sprayed from the water outlet 5 and spray it in a fan shape;

[0038] 5. When it is necessary to switch to high speed, push the bearing seat 12 on one side of the water pump 3 to move the bearing seat 12 to a position, so that the speed change wheel 19 and the matching wheel 1 21 are disengaged from each other, and the matching wheel 2 22 and the speed change wheel 2 20 are engaged with each other. At this time, the rotation speed of the rotating shaft 23 increases, so that the fan blades 7 rotate at a high speed, the sprayed atomized liquid is sprayed outward at a greater distance, and the atomization effect is better.

[0039] As described above, the driving shaft 8 maintains a constant rotation speed, and the speed of the fan blade 7 has two speeds, high speed and low speed, through the setting of the speed change wheel. In addition, it replaces the situation in the prior art where the transmission belt 16 is directly used to drive the fan blade 7 to rotate, thereby reducing the wear of the transmission belt 16, reducing energy loss, and extending the service life.

[0040] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
