Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery and equipment, and relates to auxiliary equipment for applying pesticides to plants, in particular to a walkable and adjustable pesticide application frame. Background Art

[0002] With the continuous improvement of agricultural mechanization, mechanized pesticide application has become more and more popular and plays an increasingly important role in the agricultural production process. However, the actuator of the current pesticide application machine cannot adjust the height according to the actual plant conditions when maintaining a specific pesticide application position, and the applicability of the machine is poor; in addition, when it is necessary to apply pesticides to the side of the plant, it is usually necessary to make up the pesticide, which is mostly done manually, with low work efficiency and high labor intensity.

[0003] In the prior art, when applying pesticides to densely planted crops (such as wheat, rapeseed, and rice), the width is often limited. At this time, it is necessary to replace the pesticide application frame with a larger pesticide application device to operate, which will increase the workload and the initial cost, and it cannot be used for crop fields inside the facility. Utility Model Content

[0004] In view of the shortcomings existing in the above-mentioned pesticide application process, the utility model proposes a walkable adjustable pesticide application frame, which can meet the pesticide application operations of plants with different planting widths and heights, and effectively solves the problem that traditional pesticide application devices cannot quickly adjust the pesticide application area.

[0005] The present application provides a walkable and adjustable spraying rack adopting the following technical solution:

[0006] A walkable and adjustable pesticide application rack comprises a structural frame, a driving motor connected and fixed below the structural frame, and a wheel hub connected to the driving motor; the characteristic is that the pesticide application rack comprises:

[0007] A fixing frame, connected and fixed to the structural frame;

[0008] A movable frame, the rear end of which is hingedly connected to the fixed frame;

[0009] A main push rod is connected between the fixed frame and the movable frame, so that the movable frame swings up and down relative to the fixed frame;

[0010] A main spray rod frame is hingedly connected to the front end of the mobile frame and moves up and down with the mobile frame;

[0011] A side push rod, connected and fixed to the bottom of the main spray rod frame;

[0012] The side spray rod frame is rotatably connected to the main spray rod frame, and the side spray rod frame can be unfolded and lowered under the action of the side push rod.

[0013] By adopting the above technical solution, the main push rod drives the movable frame to move up and down, thereby driving the main spray rod frame and the spray nozzle on the main spray rod frame to move up and down to meet the spraying operation of plants at different heights; the side push rod drives the side spray rod frame to expand horizontally to meet the adjustment of the spraying width.

[0014] Furthermore, the moving frame is a parallel four-bar linkage.

[0015] By adopting the above technical solution, the mobile frame is set as a parallel four-bar linkage to control the rotation of the crank rod. By utilizing the principle that the two sets of opposite sides of the parallelogram always remain parallel during the deformation process, the mobile frame can be lifted and lowered in a horizontal state at all times, making the movement of the main spray rod frame more stable and synchronized.

[0016] Furthermore, the main push rod is an upward oblique electro-hydraulic push rod, the top end of the main push rod is hinged to the movable frame through a first hinge, and the bottom end of the main push rod is hinged to the fixed frame through a second hinge. The main push rod pushes the movable frame to move, driving the main spray rod frame to perform lifting and lowering movements.

[0017] By adopting the above technical solution, the structure of the inclined upward electro-hydraulic main push rod is more compact, easy to install, occupies less space, and is simple to maintain. It can stop at any position within the specified stroke range and self-lock, and can maintain the output force unchanged, run smoothly, effectively buffer external impact force, and the stroke control is more precise.

[0018] Furthermore, the side spray boom frame is composed of a first side spray boom frame and a second side spray boom frame, the first side spray boom frame and the second side spray boom frame are both hingedly connected to the main spray boom frame, and the first side spray boom frame and the second side spray boom frame are initially vertical to the main spray boom frame.

[0019] By adopting the above technical solution, the width of the main spray boom frame is increased by the side spray boom frame to meet the requirements of pesticide application operations with different widths.

[0020] Furthermore, the side push rod is composed of a first side push rod and a second side push rod, which are respectively fixed at the bottom of the main spray rod frame. The side push rod is a horizontal electro-hydraulic push rod. The two side push rods are arranged in back-to-back working directions. The side push rods are used to realize the lateral expansion of the first side spray rod frame and the second side spray rod frame.

[0021] By adopting the above technical solution, the first side push rod and the second side push rod can automatically expand the side spray rod frame laterally during operation. After being extended, the output force can be kept unchanged, forming a stable support for the first side push rod and the second side push rod, and further expanding the lateral operation coverage of the spray rod. The two side push rods are independently driven, and the expansion angle and operation range can be adjusted separately.

[0022] Furthermore, the main spray rod frame, the first side spray rod frame and the second side spray rod frame are all connected with a mounting seat for mounting a pesticide spray nozzle, the mounting seat is L-shaped and is welded and fixed to the respective spray rod frames.

[0023] By adopting the above technical solution and the arrangement of the mounting seat, it is possible to facilitate the connection and installation of the spray nozzle at a later stage.

[0024] Furthermore, a mounting rod is connected to the middle of the main spray rod frame, and a visual recognition module is connected to the mounting rod. The visual recognition module is composed of a binocular vision sensor and a laser ranging sensor.

[0025] By adopting the above technical solution, in the later stage of pesticide application, the height and ridge width of the plant canopy area in the current operation scene can be identified through the visual recognition module, and the information can be fed back to the background operating system to adjust the operating height and width of the pesticide application frame, thereby achieving efficient and precise pesticide application operations.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. The utility model has a simple structure and is easy to adjust. The device adopts four-wheel independent drive. Compared with the traditional manual pesticide application device, it can effectively improve the walking efficiency of the device in the field.

[0028] 2. In the utility model, the main push rod drives the movable frame to move up and down, thereby driving the main spray rod frame and the spray nozzle on the main spray rod frame to move up and down to meet the spraying operation of plants at different heights.

[0029] 3. In the utility model, the side push rod can conveniently drive the side spray rod frame to expand horizontally to meet the pesticide application operation of plants with different widths. BRIEF DESCRIPTION OF THE DRAWINGS
