Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to a spraying device for intercropping crops. Background Art

[0002] In order to improve land utilization, make full use of land space, and increase crop yield per unit area of land, the intercropping method of corn and soybeans is usually adopted in the cultivation of corn and soybeans. This can not only increase crop yields, but also make full use of land resources and obtain greater benefits.

[0003] Corn is a grass crop, while soybeans are a legume. Different pesticide types and timings are used for pest and weed control. Spraying one crop can easily cause pesticide drift to another, causing damage to the other crop. This is especially true when spraying herbicides. Corn herbicides kill dicots, so drifting onto soybeans can cause damage. Soybean herbicides kill monocots, so drifting onto corn can also cause damage. Therefore, appropriate isolation measures are necessary when spraying.

[0004] Patent application number 2021201576451 discloses a device for spraying chemical control weeds for intercropping corn and soybeans, comprising a traction suspension, with enclosures provided around the upper part of the traction suspension, a first medicine box and a second medicine box installed in the enclosure, and support wheels provided at the bottom of the traction suspension. The positive effect of the present invention is that the device for spraying chemical control weeds for intercropping corn and soybeans described in the present invention can complete the separate weeding and spraying of corn rows and soybean rows in the intercropping corn and soybean fields through a one-time operation of the spraying machinery, and realize continuous operation of multiple rows of crops by rotating the nozzle rack. This application uses partitions for isolation, which belongs to a two-side blocking isolation method, wherein the spacing of the partitions can be adjusted. In this isolation method, pesticides will be emitted outward through the unobstructed position on the rear side, and the isolation effect needs to be improved.

[0005] For another example, patent application number 2023222799459 discloses an isolation and protective curtain frame and spraying vehicle for mixed planting spraying, comprising a main frame and one or more intermediate isolation frames, the lower portion of the main frame being open, curtains being installed on the front, rear, left, right, and upper sides of the main frame, the intermediate isolation frames being slidably installed within the main frame, curtains also being installed on the intermediate isolation frames, a crossbar being provided on the upper side of the main frame, the intermediate isolation frames being slidably installed on the crossbar via sliding sleeves, and the intermediate isolation frames dividing the main frame into several spraying spaces. This structural form of isolation is a fully enclosed shielding isolation method with good isolation effect, but the width of this type of isolation cover cannot be flexibly adjusted, which presents disadvantages in use.

[0006] Based on the shortcomings of the current side shielding and fully enclosed shielding forms, the inventor proposed a new intercropping crop spraying device, which can effectively improve the isolation effect by isolating the two sides and the back side. At the same time, the width of the isolation cover can be flexibly adjusted according to the crop planting width, which has promotion and application value. Utility Model Content

A small motor for driving the reel is mounted on the bracket, and the output shaft of the small motor is connected to the reel. Driven by the small motor, the reel can rotate, thereby realizing the tarpaulin retraction and deployment. When the distance between the two side baffles increases, the tarpaulin is released to a certain length. When the distance between the two side baffles decreases, the tarpaulin is retracted to a certain length. The tarpaulin isolates the rear of the equipment to prevent pesticides from being emitted outward from the unobstructed rear position. At the same time, the length of the tarpaulin can be adaptively adjusted according to the change in the distance between the two side baffles to meet the shielding requirements.

[0010] Preferably, the fixing mechanism includes a fixing plate fixedly mounted on the side baffle, a pressing plate for pressing the waterproof cloth is superimposed on the fixing plate, and the pressing plate and the fixing plate are connected by bolts.

[0012] Preferably, the drug delivery pipe of the electric sprayer is connected to the drug spraying pipe, and a plurality of spray heads distributed along the axial direction of the drug spraying pipe are provided on the drug spraying pipe. The drug spraying pipe is located below the main beam and is arranged in the same direction as the main beam.

[0013] Preferably, a vertically arranged hanging rod is installed on the main beam, and a U-shaped pipe clamp for clamping the spray pipe is provided on the hanging rod.

[0014] Preferably, the rotating shaft of each running wheel is rotatably connected to the support plate via a bearing. The upper end of the support plate is connected to a first sliding sleeve, which is sleeved on the main beam and can slide axially along the main beam. A first fastening bolt for tightening the main beam is threadedly connected to the first sliding sleeve. The first sliding sleeve and the main beam adopt a sliding fit, so that the spacing between the two running wheels can be adjusted.

[0015] Preferably, the upper end of each side guard is connected to a second sliding sleeve, which is sleeved on the main beam and can slide axially along the main beam. A second fastening bolt for tightening the main beam is threadedly connected to the second sliding sleeve. The second sliding sleeve and the main beam adopt a sliding fit, so that the spacing between the two side guards can be adjusted.

[0016] Preferably, in order to prevent the waterproof cloth from damaging the plants, the lower end of the waterproof cloth is a curtain.

[0017] The beneficial effects of the utility model are:

[0018] 1. This application can effectively improve the isolation effect by isolating the two sides and the back side. At the same time, the width of the waterproof cloth used for the back side isolation can be flexibly adjusted according to the width of the crop planting, which has promotion and application value.

[0019] 2. Driven by a small motor, the reel rotates, allowing the tarpaulin to be retracted and extended. As the distance between the two side panels increases, the tarpaulin is extended to a certain length, and as the distance between the two side panels decreases, the tarpaulin is retracted to a certain length. The tarpaulin isolates the rear of the equipment, preventing pesticides from being released from the unobstructed rear area. The length of the tarpaulin can also be adjusted adaptively based on the distance between the two side panels to meet shielding needs. BRIEF DESCRIPTION OF THE DRAWINGS
