Description

Technical Field

[0001] This utility model relates to the field of spraying structure technology, specifically to an adjustable multi-dimensional spraying device. Background Technology

[0002] With the improvement of modern agricultural mechanization, the demand for precision spraying technology in tobacco cultivation is becoming increasingly urgent. Traditional tobacco spraying operations mostly use fixed nozzles or manually adjustable spray devices, which have significant technical limitations in practical applications.

[0003] A patent with publication number CN220987328U is disclosed in the prior art. This solution includes a mixing tank, a water pump, a rotating plate, a sliding rod, a threaded rod, and a bevel gear. The stirring rod driven by the motor can make the pesticide mix more evenly. The heating plate under the mixing tank can also make the pesticide mix more thorough and even. Adjusting the lifting rod inside the adjustment device can change the height of the nozzle. The rotating plate on the base can change the spraying direction. The spray pipe and the delivery pipe are connected by a corrugated pipe to adjust the nozzle angle. The multi-directional angle and height adjustment design increases the spraying range of the pesticide, makes the spraying direction more flexible, and ensures the uniformity and comprehensiveness of the pesticide spraying.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, tobacco plants have a layered growth characteristic, and traditional equipment is difficult to achieve three-dimensional coverage of the canopy, stems and the back of leaves, resulting in insufficient uniformity of pesticide deposition.

[0006] Secondly, existing spray bar structures mostly adopt a planar layout, which cannot be dynamically adjusted according to plant height (from 0.5-1m in the seedling stage to 1.5-2.5m in the mature stage), resulting in a large amount of ineffective loss of pesticide solution.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an adjustable multi-dimensional spraying device to solve the problems of insufficient uniformity of pesticide deposition caused by the layered growth characteristics of tobacco plants and the difficulty of achieving three-dimensional coverage of the canopy, stems, and undersides of leaves in traditional technologies; and the fact that existing spray bar structures mostly adopt a planar layout, which cannot be dynamically adjusted according to plant height (from 0.5-1m in the seedling stage to 1.5-2.5m in the mature stage), resulting in a large amount of ineffective pesticide loss.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An adjustable multi-dimensional spraying device includes a connecting frame hinged to a vehicle frame, a lifting frame that moves up and down on the connecting frame, and horizontally swinging horizontal spray bars that are hinged to both ends of the lifting frame. The horizontal spray bars are also telescopically extendable along their axial direction.

[0011] The lower end of the lifting frame is provided with two longitudinal spray bars arranged side by side in the horizontal direction and swinging vertically. The area between the two longitudinal spray bars of the lifting frame is also horizontally fixed with a top spray bar.

[0012] As an optimized solution, the horizontal spray bar, the vertical spray bar, and the top spray bar are provided with several nozzles fixed in parallel.

[0013] As an optimized solution, the nozzle includes a dual-head nozzle, with the two spraying ends of the dual-head nozzle arranged vertically between each other.

[0014] As an optimized solution, a vertically mounted electric telescopic cylinder is hinged to the connecting frame, and a frame body is fixed to the upper end of the lifting frame. The telescopic end of the vertical electric telescopic cylinder is hinged to the frame body.

[0015] As an optimized solution, a lateral swing seat is hinged to the lateral end of the lifting frame, a lateral electric telescopic cylinder is horizontally fixed to the lateral swing seat, a sliding frame is fixed to the telescopic end of the lateral electric telescopic cylinder, and the lateral spray bar is fixed to the sliding frame through parallel rods.

[0016] As an optimized solution, the transverse swing seat is horizontally fixed to a transverse slide rail along the sliding direction of the sliding frame, and a transverse slide block that matches the transverse slide rail is fixed to the side wall of the sliding frame.

[0017] As an optimized solution, a vertical support cylinder is vertically fixed to the horizontal end of the lifting frame, and a vertical support shaft is vertically fixed to the horizontal swing seat and rotatably inserted into the vertical support cylinder. A vertical stop knob is threaded onto the vertical support cylinder, and the end of the vertical stop knob abuts against the vertical support shaft.

[0018] As an optimized solution, two vertical stop grooves are formed on the peripheral wall of the vertical support shaft, and the two vertical stop grooves are arranged vertically between each other. The end of the vertical stop knob abuts against one of the vertical stop grooves.

[0019] As an optimized solution, the lifting frame is horizontally fixed with a transverse support cylinder for each of the longitudinal spray bars. A transverse support shaft is fixed to the longitudinal spray bar and rotatably inserted into the transverse support cylinder. A transverse stop knob is threaded onto the transverse support cylinder, and the end of the transverse stop knob abuts against the transverse support shaft.

[0020] As an optimized solution, two transverse stop grooves are formed on the peripheral wall of the transverse support shaft. The two transverse stop grooves are coaxially arranged, and the end of the transverse stop knob abuts against one of the transverse stop grooves.

[0021] As an optimized solution, the transverse support cylinder is fixed to the front end of the lifting frame via a connecting column.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] First, it achieves three-dimensional dynamic coverage by coordinating the horizontal and vertical spray booms, breaking through the traditional planar spraying mode and realizing three-dimensional application of pesticides to the tobacco canopy, stems, and the back of leaves. The uniformity of pesticide deposition is improved by more than 40%, and the blind spots of application are significantly reduced.

[0024] Secondly, it adapts to different growth stages: the height adjustment matches the tobacco plant height range of 0.5-2.5m, and with the multi-angle deflection of the spray boom, it ensures precise and targeted application of pesticides from the seedling stage to the maturity stage, increasing the pesticide utilization rate to over 85%.

[0025] Third, operational efficiency is optimized: the modular spray boom structure simplifies the traditional complex transmission system, reduces maintenance costs by 30%, and adapts to the high-efficiency operation needs of tobacco fields of different sizes;

[0026] Two horizontal spray bars are installed on both sides of the lifting frame. During operation, the two horizontal spray bars can be extended horizontally, and when not in operation, they can be rotated to the sides of the lifting frame.

[0027] The longitudinal spray bar is installed at the front end of the lifting frame. During operation, the longitudinal spray bar is set downwards, and when not in operation, it can be manually rotated to the top to reduce the space occupied by the equipment. The vertical electric telescopic cylinder connected to the connecting frame drives the lifting frame to rise and fall, adjusting the overall height of the spraying device.

[0028] Nozzles are arranged at appropriate intervals on the horizontal spray bar, the vertical spray bar, and the top spray bar. Each spray bar is equipped with a pipe switch to control the opening and closing of the pipe. Attached Figure Description

[0042] Two vertical stop grooves are provided on the peripheral wall of the vertical support shaft 16. The two vertical stop grooves are set vertically between each other.
