Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment, and in particular to a foliar fertilizer spraying device. Background Technology

[0002] Tobacco is an annual herbaceous plant, typically 1-3 meters tall. Its stem is erect, covered with glandular hairs, and relatively brittle. The main stem is stout, continuously growing from the terminal bud, with nodes bearing leaves. Axillary buds can also emerge from the leaf axils. In tobacco cultivation, proper foliar fertilization plays a crucial role in improving leaf quality and yield. Existing foliar fertilizer spraying devices can meet basic spraying needs, but uneven contact between the sprayed fertilizer solution and the leaf surface leads to uneven nutrient absorption, negatively impacting tobacco growth.

[0003] A search revealed a Chinese patent document (authorization announcement number CN113875380B), which discloses a tobacco foliar fertilizer spraying device and its usage method, relating to the technical field of foliar fertilizer spraying devices. This tobacco foliar fertilizer spraying device and its usage method include a water storage tank, a pump body, and a spray pipe. Both the water storage tank and the pump body are mounted on a transport vehicle frame. The outlet of the water storage tank is connected to the inlet of the pump body via a pipeline, and the outlet of the pump body is connected to the inlet of the spray pipe via a flexible hose. A valve body is installed at the water outlet at the bottom of the water storage tank, and the pipeline at the water outlet is controlled to open and close via the valve body. The spray pipe is engaged with a placement frame on the transport vehicle frame, and a motor is mounted on the placement frame to drive the spray pipe to swing vertically for bidirectional spraying. This invention, by setting up a water storage tank, pump body, spray pipe, transport vehicle frame and motor, achieves efficient and comprehensive spraying, solving the problems of uneven and incomplete spraying, difficulty in spraying obscured areas, and high workload of manual fertilizer spraying when spraying tobacco foliar fertilizer. This foliar fertilizer spraying device can meet basic spraying needs, but the sprayed fertilizer solution does not contact the leaf surface evenly, resulting in uneven nutrient absorption and affecting tobacco growth. Utility Model Content

[0004] The purpose of this invention is to provide a foliar fertilizer spraying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foliar fertilizer spraying device, comprising a pusher frame for supporting the foliar fertilizer spraying process, an I-shaped frame welded to one end of the pusher frame, a forward rotating motor and a reverse rotating motor mounted on the top of the I-shaped frame, the output shafts of the forward rotating motor and the reverse rotating motor being connected to lead screws via couplings, a limit groove installed on one side of the I-shaped frame, hollow columns welded to the transverse inner walls of the I-shaped frame, springs installed inside the hollow columns, a movable column connected to one end of the springs, a contact point one installed at one end of the movable column, two contacts symmetrically installed on the transverse inner walls of the I-shaped frame, an arc-shaped plate installed at the other end of the movable column, and a guide column welded to one side of the I-shaped frame.

[0006] Preferably, a movable connecting frame is engaged with the outer periphery of the lead screw, a hollow block is connected to one end of the movable connecting frame, a spray frame is installed on the side of the hollow block, and a conveying pipe is connected to the outer periphery of the spray frame.

[0007] Preferably, both ends of the spray frame are connected to a spray collection hood, and a rotating disk is rotatably connected inside the spray collection hood, with oblique holes provided on the surface of the rotating disk.

[0008] Preferably, the two ends of the spray frame are connected to nozzles for foliar fertilizer spraying, the outer periphery of the spray collection hood is connected to a ventilation pipe, and one end of the ventilation pipe is connected to the movable connecting frame.

[0009] Preferably, the surface of the movable connecting frame is provided with an air inlet, and a fan is installed inside the air inlet.

[0010] Preferably, a pusher wheel is installed inside the pusher frame, a drive gear is installed on the side of the pusher wheel, a chain is meshed with the outer circumference of the drive gear, a driven gear is meshed with the inner ring of the chain, a rotating connector is rotatably connected to the side of the driven gear, a transmission rod is connected to the outer circumference of the rotating connector, and a pressure rod is installed at one end of the transmission rod.

[0011] Preferably, a liquid storage tank is installed on the top of the pusher, and the top of the liquid storage tank is connected to the delivery pipeline.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This foliar fertilizer spraying device, thanks to its structure of a moving column and an arc-shaped plate, uses a forward-rotating motor to drive a lead screw, which in turn moves a moving connecting frame and a hollow block downwards along the guide column. This downward movement of the spray frame and the moving connecting frame eventually brings the spray frame into contact with the arc-shaped plate. The arc-shaped plate then presses down on the moving column and spring, causing contact point two to make contact with contact point one. The forward-rotating motor then stops, and the reverse-rotating motor rotates, driving the lead screw in the opposite direction. The lead screw then moves the moving connecting frame and the hollow block upwards along the guide column. By repeating these steps, the spray frame can move up and down repeatedly, resulting in more thorough fertilization of the tobacco leaves. Compared to traditional devices where the fertilizer solution sprays unevenly onto the leaves, this structure allows for reciprocating spraying, leading to more uniform nutrient absorption and improved tobacco growth.

[0014] This foliar fertilizer spraying device benefits from the structure of the rotating disc and the inclined holes. The fan drives air into the ventilation pipe and the inside of the spray hood through the air inlet. The air is discharged through the inclined holes. Due to the inclined angle arrangement of the inclined holes, the air drives the rotating disc to rotate. The air blown out will rotate and blow out the fertilizer liquid sprayed from the nozzle, improving the uniformity of spraying. Attached Figure Description

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0024] like Figures 1 to 4The foliar fertilizer spraying device shown includes a pusher frame 1 for supporting the foliar fertilizer spraying process. The pusher frame 1 is manually pushed and travels between rows of planted tobacco. A I-beam frame 3 is welded to one end of the pusher frame 1. A forward rotation motor 301 and a reverse rotation motor 302 are installed on the top of the I-beam frame 3. The output shafts of the forward rotation motor 301 and the reverse rotation motor 302 are both connected to lead screws 303 via couplings. A limit groove 304 is installed on one side of the I-beam frame 3. Hollow columns 305 are welded to the transverse inner walls of the I-beam frame 3. Springs 306 are installed inside the hollow columns 305. A moving column 309 is connected to one end of the spring 306. A contact point 307 is installed at one end of the moving column 309. Contact points 308 are symmetrically installed on the transverse inner walls of the I-beam frame 3. An arc-shaped plate 310 is installed at the other end of the moving column 309. A guide post 404 is welded to one side of the I-beam frame 3. When the forward rotation motor 301 is turned on, the forward rotation motor 301 drives the lead screw 303 to rotate. The lead screw 303 drives the movable connecting frame 4 and the hollow block 205 to move downward along the direction of the guide post 404, thereby driving the spray frame 2 and the movable connecting frame 4 to move downward. Finally, the spray frame 2 contacts the arc plate 310. The arc plate 310 presses down the movable post 309 and the spring 306. Finally, the second contact point 308 and the first contact point 307 contact each other. The forward rotation motor 301 stops working, and the reverse rotation motor 302 rotates. The reverse rotation motor 302 drives the lead screw 303 to reverse. The lead screw 303 drives the movable connecting frame 4 and the hollow block 205 to move upward along the direction of the guide post 404. By repeating the above steps, the spray frame 2 can move up and down reciprocally, so as to fertilize the tobacco leaves more thoroughly.

[0025] A movable connecting frame 4 is engaged with the outer periphery of the lead screw 303. A hollow block 205 is connected to one end of the movable connecting frame 4. A spray frame 2 is installed on the side of the hollow block 205. A conveying pipe 109 is connected to the outer periphery of the spray frame 2. The conveying pipe 109 is corrosion-resistant, pressure-resistant, and flexible, and is usually made of plastic hose (such as PVC pipe, PE pipe) or metal hose. A liquid storage tank 101 is installed on the top of the pusher 1. The liquid storage tank 101 is a container for storing foliar fertilizer solution. Its material is usually made of corrosion-resistant plastic or metal, such as polyethylene plastic or stainless steel. The top of the liquid storage tank 101 is connected to the conveying pipe 109. The pressure rod 102 sprays the fertilizer solution inside the liquid storage tank 101 through the conveying pipe 109 and the spray frame 2 from the nozzle 202 to fertilize the tobacco leaves.

[0026] Both ends of the spray frame 2 are connected to a collecting hood 201. A rotating disk 203 is rotatably connected inside the collecting hood 201. The surface of the rotating disk 203 is provided with oblique holes 204. Both ends of the spray frame 2 are connected to nozzles 202 for foliar fertilizer spraying. The nozzles 202 are components that atomize the foliar fertilizer solution and spray it onto the tobacco leaves. There are many types of nozzles 202, which can be divided into fan-shaped nozzles, cone nozzles, and hollow cone nozzles according to the spray shape. Fan-shaped nozzles have a larger spray angle and are suitable for large-area horizontal spraying; cone nozzles and hollow cone nozzles can produce a more concentrated spray and are suitable for more targeted spraying. There are also various choices for the nozzle's spray orifice size. The smaller the orifice size, the better the atomization effect, but the more prone it is to clogging. The selection needs to be based on the properties of the foliar fertilizer solution and the spraying requirements. The outer periphery of the spray hood 201 is connected to a ventilation pipe 403. One end of the ventilation pipe 403 is connected to a movable connecting frame 4. The surface of the movable connecting frame 4 is provided with an air inlet 401. A fan 402 is installed inside the air inlet 401. When the fan 402 is turned on, the fan 402 drives air to enter the ventilation pipe 403 and the interior of the spray hood 201 through the air inlet 401. The air is discharged through the inclined holes 204. Due to the inclined angle arrangement of the inclined holes 204, the air drives the rotating disk 203 to rotate. The blown air will rotate and blow out the fertilizer liquid sprayed from the nozzle 202, improving the uniformity of spraying.

[0027] The pusher frame 1 has a pusher wheel 105 installed inside. A drive gear 106 is installed on the side of the pusher wheel 105. A chain 108 is meshed with the outer circumference of the drive gear 106. A driven gear 107 is meshed with the inner ring of the chain 108. A rotating connector 104 is rotatably connected to the side of the driven gear 107. A transmission rod 103 is connected to the outer circumference of the rotating connector 104. A pressure rod 102 is installed at one end of the transmission rod 103. During movement, the pusher wheel 105 drives the drive gear 106 to rotate. The drive gear 106 drives the driven gear 107 and the rotating connector 104 to rotate through the chain 108. The rotating connector 104 drives the transmission rod 103 and the pressure rod 102 to move up and down.

[0028] Working principle

[0029] In use, the foliar fertilizer spraying device involves a hand-push pusher frame 1 moving between rows of tobacco plants. During this movement, the pusher wheel 105 drives the drive gear 106 to rotate. The drive gear 106, via the chain 108, drives the driven gear 107 and the rotating connector 104 to rotate. The rotating connector 104 drives the transmission rod 103 and the pressure rod 102 to move up and down. The pressure rod 102 sprays the fertilizer solution inside the storage tank 101 through the delivery pipe 109 and the spray frame 2 from the nozzle 202 to fertilize the tobacco leaves. The forward rotation motor 301 is then turned on, driving the lead screw 303 to rotate. The lead screw 303 drives the movable connecting frame 4 and the hollow block 205 to move downwards along the guide column 404, thereby causing the spray frame 2 and the movable connecting frame 4 to move downwards. Finally, the spray frame 2 and the arc plate 310... Upon contact, the arc plate 310 presses down on the moving column 309 and the spring 306, and finally the second contact point 308 and the first contact point 307 make contact. The forward motor 301 stops working, and the reverse motor 302 rotates. The reverse motor 302 drives the lead screw 303 to reverse, and the lead screw 303 drives the moving connecting frame 4 and the hollow block 205 to move upward along the guide column 404. By repeating the above steps, the spray frame 2 can be moved up and down to make the fertilization of tobacco leaves more thorough. The fan 402 is turned on, and the fan 402 drives the air to enter the ventilation pipe 403 and the interior of the spray hood 201 through the air inlet 401. The air is discharged through the inclined hole 204. Due to the inclined angle arrangement of the inclined hole 204, the air drives the rotating disk 203 to rotate. The blown air will rotate and blow out the fertilizer liquid sprayed from the nozzle 202, improving the uniformity of spraying.
