[0026] Example

[0027] Reference Figure 1-Figure 4 , which is an embodiment of the present invention, provides an intermittent herbicide quantitative spraying device, including: a water supply unit 100 and a quantitative spraying unit 200.

[0028] The water supply unit 100 includes a mobile base 101, a frame 102 is fixedly installed on the top of the mobile base 101, a transfer pipe 103 is fixedly connected to the frame 102, and a water supply pipe 104 is connected to the transfer pipe 103; the water supply pipe 104 is connected to the water tank 105 through a water pump 106, and the water pump 106 transports the herbicide solution in the water tank 105 to the transfer pipe 103 through the water supply pipe 104.

[0029] The quantitative spraying unit 200 includes a movable water tank 201 located inside the transfer tube 103, and the movable water tank 201 is communicated and rotatably connected to the transfer tube 103. A plurality of quantitative cylinders 202 are fixedly arranged inside the movable water tank 201, and a piston 203 is slidably connected inside the quantitative cylinder 202. One end of the piston 203 is fixedly connected to a push rod 204, and one end of the push rod 204 passes through the movable water tank 201 and extends to the outside of the movable water tank 201. One end of the quantitative cylinder 202 passes through the movable water tank 201 and extends to the outside of the movable water tank 201. A nozzle 205 is provided at one end of the quantitative cylinder 202 located outside the movable water tank 201. The quantitative spraying unit 200 also includes an intermittent pushing component 206 for intermittently driving the push rod 204. When the push rod 204 is pushed to drive the piston 203 to slide toward the nozzle 205 inside the metering cylinder 202, the herbicide solution is pushed out of the metering cylinder 202 and sprayed through the nozzle 205. When the push rod 204 drives the piston 203 to slide away from the nozzle 205 inside the metering cylinder 202, negative pressure is generated in the metering cylinder 202, so that the water inside the movable water tank 201 flows through the water inlet 207 into the metering cylinder 202. Since the stroke of the piston 203 in the metering cylinder 202 is fixed, the amount of herbicide sprayed is the same, thereby achieving accurate metering and spraying of the herbicide.

[0030] In another embodiment, a water inlet 207 is provided on the metering cylinder 202 , and the metering cylinder 202 is connected to the movable water tank 201 through the water inlet 207 .

[0031] In another embodiment, a sealing plate 208 is provided inside the metering cylinder 202, and the water inlet 207 is located on the moving path of the sealing plate 208. A slide bar 210 is fixedly connected to the inside of the metering cylinder 202, and the slide bar 210 passes through the sealing plate 208. A spring 211 is sleeved on the outer surface of the slide bar 210, and the spring 211 is located between the slide bar 210 and the inner wall of the metering cylinder 202. By setting the sealing plate 208 and the spring 211, when the internal pressure of the metering cylinder 202 is negative, the water in the movable water tank 201 can enter the metering cylinder 202. When the internal pressure of the metering cylinder 202 is high, the sealing plate 208 closes the water inlet 207, so that the herbicide is sprayed at high pressure.

[0032] In another embodiment, the intermittent pushing assembly 206 includes a connecting rod 2061 fixedly connected to the push rod 204, the connecting rod 2061 is vertically arranged between the push rod 204, and a turntable 2062 is sleeved on the connecting rod 2061, and the turntable 2062 is rotatably connected to the connecting rod 2061.

[0033] In another embodiment, a drive motor 2063 is fixedly mounted on the vehicle frame 102, and an output end of the drive motor 2063 is fixedly connected to the turntable 2062. When the drive motor 2063 is activated, the turntable 2062 rotates, which drives the linkage rod 2061 to rotate periodically in the horizontal direction, and the linkage rod 2061 drives the push rod 204 to reciprocate in the horizontal direction.

[0034] In another embodiment, a water tank 105 is fixedly connected to the frame 102 , a water pump 106 is installed on the water supply pipe 104 , one end of the water supply pipe 104 is connected to the water tank 105 , and the water pump 106 is installed on the water tank 105 .

[0035] During use, a frame 102 is fixedly mounted on the mobile base 101, a transfer pipe 103 is fixedly connected to the frame 102, a water supply pipe 104 is connected to the water tank 105 through a water pump 106, and the water pump 106 transports the herbicide solution in the water tank 105 to the transfer pipe 103 through the water supply pipe 104, and a piston 203 is slidably connected to the inside of each metering cylinder 202, and one end of the piston 203 extends to the outside of the movable water tank 201 through the push rod 204. One end of the metering cylinder 202 extends to the outside through the movable water tank 201 and is provided with a nozzle 205. When the driving motor 2063 is started, the turntable 2062 rotates, and the turntable 2062 drives the connecting rod 2061 to rotate periodically. The connecting rod 2061 drives the push rod 204 to reciprocate horizontally. When the push rod 204 is pushed to drive the piston 203 to slide toward the nozzle 205 inside the metering cylinder 202, the herbicide solution is pushed out of the metering cylinder 202 and sprayed through the nozzle 205. When the push rod 204 drives the piston 203 to slide away from the nozzle 205 inside the metering cylinder 202, the herbicide solution is pushed out of the metering cylinder 202 and sprayed through the nozzle 205. When the piston 203 is moved, negative pressure is generated in the metering cylinder 202, so that the water in the movable water tank 201 flows into the metering cylinder 202 through the water inlet 207, and pushes open the sealing plate 208 to squeeze the spring 211, thereby refilling the metering cylinder 202 with herbicide. Since the stroke of the piston 203 in the metering cylinder 202 is fixed, the amount of herbicide sprayed is the same. By continuously rotating the turntable 2062 and repeating the above steps, intermittent and quantitative spraying of herbicides is achieved. Compared with the continuous spraying device, the present invention has lower cost and is easy to operate, and is suitable for efficient management of large areas of farmland.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
