Description

Technical Field

[0001] This utility model relates to the field of agricultural production equipment, and in particular to a pneumatic orchard sprayer. Background Technology

[0002] In the field of orchard plant protection, wind-driven sprayers are key equipment for achieving efficient spraying of fruit trees. However, traditional models have significant technical limitations and are difficult to adapt to the spraying needs of fruit trees of different heights.

[0003] Firstly, the functional modes are fixed and cannot be flexibly switched. Traditional sprayers often have a linked design between the fan and the spraying mechanism. When the fan starts, spraying is always accompanied, and the fan cannot be turned off independently. For low-growing fruit trees, the strong airflow generated by the fan can easily cause the spray to drift and be wasted. For tall fruit trees, if the fan power is fixed, it may not be able to deliver the spray to the top of the canopy, or the spray adhesion rate may decrease due to excessive wind speed. It is difficult to ensure the accuracy of spraying for fruit trees of different heights.

[0004] Secondly, the reliability of the power transmission is insufficient. Traditional models generally use belt drives to connect the power source to the fan and plunger pump. During long-term high-speed operation, the belt is prone to aging and loosening due to friction, which leads to transmission slippage. This not only causes power loss, unstable wind speed and pump pressure, affecting the application effect, but also requires frequent belt replacement, increasing maintenance costs and downtime. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic orchard sprayer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic orchard sprayer, comprising a frame, a head unit at one end of the frame, an auxiliary blower mechanism and a pesticide spraying mechanism at the other end of the frame, and a direct-drive clutch on the frame.

[0007] In a preferred embodiment of this utility model, the auxiliary blower mechanism includes a power mechanism. A direct-drive clutch, a transmission box, and a transfer case are sequentially arranged on the frame from one end of the front of the vehicle. The power mechanism is driven by the direct-drive clutch, the direct-drive clutch is driven by the transmission box, and the transmission box is driven by the transfer case. A universal coupling is driven by one end of the transfer case. A partition plate is connected to the end of the frame away from the front of the vehicle. A rotary bearing is provided on the partition plate. A blower is located at the end of the partition plate away from the front of the vehicle. A transmission rod is connected to the other end of the partition plate. One end of the transmission rod is connected to one end of the universal coupling. The transmission rod extends to the other side of the rotary bearing and is connected to a fan. The fan is movably disposed inside the blower.

[0008] As a preferred embodiment of this utility model, the medicine spraying mechanism includes a medicine pot, which is located above the power mechanism. A four-cylinder plunger pump is provided between the partition plate and the transfer case. The four-cylinder plunger pump is poweredly connected to the transfer case. The medicine pot and the four-cylinder plunger pump are connected through a pipe. An annular pipe is provided on the partition plate. The four-cylinder plunger pump is connected to the annular pipe through a pipe. A pair of annular pipes are symmetrically arranged on the partition plate. Several nozzles are evenly provided on the annular pipes, and the nozzles extend to the middle of the partition plate.

[0009] As a preferred embodiment of this invention, wheels are provided on both sides of the transmission box, and the wheels are connected to the transmission box in a transmission manner.

[0010] As a preferred embodiment of this utility model, a seat is provided on the side of the front of the vehicle near the partition plate, and a canopy is provided on the medicine pot.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. The fan and plunger pump can be independently controlled through the transfer case. For low-growing fruit trees, the plunger pump can be used alone for precise spraying, avoiding pesticide drift and damage to the fruit trees caused by the strong airflow of the fan. For tall fruit trees, the fan power is combined with the fan airflow to atomize the pesticide a second time, improve the pesticide adhesion rate, achieve full tree coverage, meet the application needs of fruit trees of different heights, and significantly enhance the applicability.

[0013] 2. By replacing traditional belt drives with automotive direct-drive clutches, the problems of belt aging and slippage are completely solved. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a technical solution: a pneumatic orchard sprayer, such as... Figure 1 , Figure 2 As shown, the vehicle includes a frame 1, one end of which is provided with a front end 101, and the other end of which is provided with an auxiliary blower mechanism 2 and a chemical spraying mechanism 3. A direct-drive clutch 202 is provided on the frame 1.

[0022] like Figures 2-5 As shown, the auxiliary blower mechanism 2 includes a power mechanism 201. A direct-drive clutch 202, a transmission box 203, and a transfer case 204 are sequentially arranged on the frame 1 from one end of the front end 101. The power mechanism 201 is driven by the direct-drive clutch 202, which is driven by the transmission box 203. The transmission box 203 is driven by the transfer case 204. A universal coupling 205 is driven by one end of the transfer case 204. A partition plate 206 is connected to the end of the frame 1 away from the front end 101. The partition plate 206 is equipped with a rotary bearing 206-1. A blower 207 is provided at one end of the partition plate 206 away from the front of the vehicle 101. A transmission rod 208 is connected to the other end of the partition plate 206. One end of the transmission rod 208 is connected to one end of the universal coupling 205. The transmission rod 208 extends to the other side of the rotary bearing 206-1 and is connected to a fan 209. The fan 209 is movably installed inside the blower 207. The speed of the fan 209 can be adjusted (1500 / 2400) through the transfer case 204.

[0023] like Figure 4 , Figure 5As shown, the medicine spraying mechanism 3 includes a medicine tank 301, which is located above the power mechanism 201. A four-cylinder plunger pump 302 is provided between the partition plate 206 and the transfer case 204. The four-cylinder plunger pump 302 is poweredly connected to the transfer case 204. The transfer case 204 can drive the fan 209 or the four-cylinder plunger pump 302 respectively. The medicine tank 301 and the four-cylinder plunger pump 302 are connected by a pipe. An annular pipe 303 is provided on the partition plate 206. The four-cylinder plunger pump 302 is connected to the annular pipe 303 by a pipe. A pair of annular pipes 303 are symmetrically arranged on the partition plate 206. Several nozzles 304 are evenly arranged on the annular pipes 303, and the nozzles 304 extend to the middle of the partition plate 206.

[0024] like Figure 1 , Figure 4 As shown, wheels 103 are provided on both sides of the transmission box 203, and the wheels 103 are connected to the transmission box 203 in a transmission connection.

[0025] like Figure 1 , Figure 2 As shown, a seat 102 is provided on the side of the front of the vehicle 101 near the partition plate 206.

[0026] In practice, prepare the medicine solution according to the ratio, pour it into the medicine pot 301, and after checking that all parts are connected normally, start the power mechanism 201. The medicine pot 301 is equipped with a canopy 4.

[0027] The power mechanism 201 drives the transfer case 204, which drives the fan 209 to start rotating through the universal coupling 205 and the transmission rod 208. Alternatively, the transfer case 204 drives the four-cylinder plunger pump 302 to pressurize the medicine through the medicine bottle 301 and pump it into the annular pipe 303, and finally spray it out through the nozzle 304.

[0028] When spraying pesticides on low-growing fruit trees, the operation of the transfer case 204 cuts off the power to the blower, stopping the fan 209 and leaving only the four-cylinder plunger pump 302 running. The pesticide solution is drawn from the sprayer 301 into the four-cylinder plunger pump 302, pressurized, and then transported through the pipeline to the annular pipe 303, where it is sprayed directly from the nozzle 304, making it suitable for precise spraying of low-growing fruit trees.

[0029] When spraying pesticides on tall fruit trees, operate the transfer case 204 to engage the fan power. The fan speed 209 is selected according to the tree height and adjusted via the transfer case 204 to 1500 rpm or 2400 rpm.

[0030] When the fruit trees are tall, use the high speed setting of 2400 RPM and use the high airflow area in the middle of the blower 207 to blow the liquid to the top of the tree canopy;

[0031] For medium-height fruit trees, use a low speed of 1500 RPM to reduce pesticide waste.

[0032] After being pressurized by the four-cylinder plunger pump 302, the liquid medicine is sprayed out from the nozzle 304. The airflow of the fan, especially the wide area in the middle of the fan 209, atomizes the liquid medicine a second time. The atomized liquid medicine is evenly covered on the tall fruit trees through the opening of the blower 207, which is wider at the top and narrower at the bottom.

[0033] The operator controls the vehicle's speed via seat 102, adjusting the speed of the direct-drive clutch 202 according to the density of the fruit trees. To switch between spraying only and air-assisted atomization modes, the operator can adjust the speed in real-time via the transfer case 204, without needing to stop the machine.

[0034] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
