[0002] The intercropping pattern in the field can increase crop yields. In intercropping of crops, a method of spraying a specific pesticide on an entire area is generally used. This comprehensive spraying method will have a negative impact on some crops. In areas where soybeans and corn are cropped together, soybeans are dicotyledons and corn are monocotyledons. The best herbicide for soybeans is mainly used to eliminate monocotyledons, while the best herbicide for corn is mainly used to eliminate dicotyledons. As a result, the weed control effect of spraying the same liquid on the entire area cannot be optimized, and may even cause damage to soybean or corn crops.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] This embodiment takes soybean and corn intercropping as an example to provide a sprayer for compound crop planting. Figure 1 , 2 , 3, including:

[0035] In a first aspect, a sprayer for compound crop planting is provided, comprising:

[0036] The sprayer body includes a frame 1, running wheels 2 and a power device 3 for driving the running wheels 2. The power device 3 may be an electric motor or an engine.

[0037] The liquid supply assembly includes a liquid supply box 4, and the liquid supply box 4 is connected to a liquid supply pump 5 through a liquid infusion tube; in the embodiment of the present invention, the liquid supply box may include two, and the two liquid supply boxes respectively contain corn liquid for corn spraying and soybean liquid for soybean spraying, and the two liquid supply boxes are respectively connected to independent liquid supply pumps 5 to provide spraying power. Of course, only one liquid supply box may be provided, in which case only water is contained in the liquid supply box, and there is another medicine box for containing medicine separately, and the medicine and water are mixed online during the transportation process to realize spraying.

[0038] The spray assembly includes a bracket 6, a nozzle 7, and a detachable baffle plate 8. The nozzle 7 includes a first nozzle 701 and a second nozzle 702. The first nozzle 701 and the second nozzle 702 are arranged on the bracket 6 front and back. Preferably, the first nozzle 701 and the second nozzle 702 can be hard pipes. The first nozzle 701 and the second nozzle 702 are arranged horizontally and parallel on the bracket. A plurality of nozzles 9 are arranged oppositely on the first nozzle 701 and the second nozzle 702. The bracket 6 is provided with a plurality of pairs of slots 10 adapted to the baffle plate 8. The baffle plate 8 blocks the nozzles 9 on the first nozzle 701 and the second nozzle 702 when installed. Preferably, the baffle plate is perpendicular to the first nozzle 701 and the second nozzle 702 when installed. Figure 4 , Figure 5 As shown, the shielding plate 8 includes an A surface and a B surface, and a contact unit 11 is also provided on the shielding plate 8. The contact unit 11 includes a first contact unit 11a and a second contact unit 11b. The first contact unit 11a is provided at the front end top of the A surface, and the second contact unit 11b is provided at the rear end top of the B surface. A contact sensing unit 12 adapted to the contact unit 11 is provided in the slot 10. When the shielding plate is adapted to the slots corresponding to the first nozzle and the second nozzle, respectively, the first contact unit 11a of the A surface of the shielding plate contacts the contact sensing unit 12 in the slot corresponding to the first nozzle, and the second contact unit 11b of the B surface of the shielding plate contacts the contact sensing unit 12 in the slot corresponding to the second nozzle. Preferably, the contact sensing unit 12 is a contact sensor. The contact sensing unit 12 is connected to a control system, and is used to control the nozzles on the first nozzle and the second nozzle to spray continuously and without repetition in the spray width direction, effectively controlling the precise spraying of the soybean liquid and the corn liquid without causing re-spraying and missed spraying.

[0039] like Figure 3 , Figure 4 As shown, taking corn and soybean intercropping as an example, the spray assembly includes four shielding plates a, b, c, and d, respectively, and the four shielding plates are respectively adapted to be installed in the slots on the first nozzle and the second nozzle. The first nozzle is a corn nozzle, and the second nozzle is a soybean nozzle. Figure 4It can be seen that the contact sensing situation between the contact unit of the baffle plate and the first nozzle is: the opposite surface between the baffle plate a and the baffle plate b is B surface-B surface, the opposite surface between the baffle plate b and the baffle plate c is A surface-A surface, and the opposite surface between the baffle plate c and the baffle plate d is B surface-B surface; since the first contact unit 11a of the A surface of the baffle plate is arranged at the front end top of the A surface, the first contact unit 11a of the A surface of the baffle plate in the adapted state contacts the contact sensing unit 12 in the corresponding slot of the first nozzle, and since the second contact unit 11b of the B surface is located at the rear end of the B surface, when the B surface is installed, its second contact unit 11b has no inductive contact with the contact sensing unit corresponding to the first nozzle in front, so the solenoid valve of the nozzle between the B surface and the B surface is not conductive, and then the nozzle spraying operation between the A surface and the A surface corresponding to the baffle plate b and the baffle plate c on the first nozzle is obtained, and only the corn liquid is sprayed. Similarly, when the B surfaces of the four shielding plates are installed, their second contact units 11b are in inductive contact with the contact sensing units corresponding to the second nozzles, and the nozzle solenoid valves between the B surfaces and B surfaces corresponding to the shielding plates a and b, and the shielding plates c and d on the second nozzles are connected, and the corresponding nozzles spray the soybean liquid, while the nozzles between the shielding plates b and c on the second nozzles do not spray. The present invention only installs shielding plates, and the contact sensing points of the contact units on the shielding plates and the contact sensing units in the slots are different, thereby controlling the nozzles on the first nozzle and the second nozzle to spray continuously and non-repetitively in the spray width direction, so as to achieve the goal of preventing the liquid from drifting when spraying intercropped crops, and achieving accurate and effective operations, which is convenient and fast.

[0040] In the embodiment of the present invention, the bracket 6 includes a first bracket 601 and a second bracket 602 for setting the slots. The first bracket 601 and the second bracket 602 are parallel and located on both sides of the first nozzle 701 and the second nozzle 702 respectively.

[0041] In the embodiment of the present invention, the first contact unit 11a and the second contact unit 11b of the shielding plate 8 are provided with marks, and the marks include colors and / or texts, so that people can install the shielding plate more clearly without causing mis-installation.

[0042] In the embodiment of the present invention, the shielding plate 8 is located below the first nozzle 701 and the second nozzle 702 in the adapted state, so that the shielding plate is easy to assemble and disassemble, and the design structure is simple.

[0043] The spray control method of the spray machine for composite crop planting of the present invention comprises:

[0044] S1: Install several shielding plates in the slots according to the width and spraying requirements of the composite crop;

[0045] S2: The first contact unit and the second contact unit of the shielding plate contact and trigger the contact sensing unit in the slot;

[0046] S3: The control system obtains the contact information of the contact sensing unit, and controls the overall on or off of the nozzle solenoid valves between the shielding plates according to the contact information, so as to realize that the nozzles on the first nozzle and the second nozzle spray continuously and do not repeat in the spray direction. In the embodiment of the present invention, the overall on or off of the nozzle solenoid valves between the shielding plates according to the contact information is specifically controlled as follows:

[0047] Determine the opposite surfaces of adjacent shielding plates according to the contact information generated by the first contact unit on the A surface of each shielding plate and the second contact unit on the B surface; specifically, the first contact unit on the A surface of the shielding plate senses contact with the contact sensing unit corresponding to the first nozzle to generate contact information, and the second contact unit on the B surface of the shielding plate senses contact with the contact sensing unit corresponding to the second nozzle to generate contact information;

[0048] When the opposite surfaces between the two shielding plates are surface A-surface A, the nozzle solenoid valve of the first nozzle corresponding to surface A-surface A is controlled to be turned on, which is the first nozzle spray operation section;

[0049] When the opposite surfaces between the two shielding plates are B surface-B surface, the nozzle solenoid valve of the second nozzle corresponding to the B surface-B surface is controlled to be turned on, which is the second nozzle spray operation section.

[0050] The sprayer of the present invention is provided with two nozzles, and the nozzles are separated by a shielding plate to prevent the drift of different liquid medicines and damage to crops, so that the spraying operation of intercropping crops can be realized. At the same time, the shielding plate also acts as a control switch when in use, so that the sprayer can realize that the nozzles on the first nozzle and the second nozzle spray different liquid medicines continuously and without duplication in the spraying direction, and the precise spraying control of the liquid medicine is convenient and effective.
