Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a spraying component used in an automatic spraying machine terminal. Background Art

[0002] Large-scale planting of crops is the trend of modern agriculture. In recent years, the planting area has gradually expanded. Under this situation, traditional spraying equipment such as backpack sprayers can hardly meet the production needs and will be gradually eliminated. They will be replaced by some more efficient and labor-saving automatic spraying equipment. Automatic spraying machine is an automatic spraying equipment suitable for field crops. It is usually composed of several parts such as walking device, medicine tank, pressure component and spraying component. The spraying component usually includes a horizontal support arm, on which equidistantly distributed spray heads are fixed, and the spray head is connected to the medicine tank through a hose. Based on the above structure adopted by the spraying component, during the spraying operation, the liquid medicine is easy to drift around after atomization. On the one hand, it will spread into the air to cause greater pollution, especially causing serious health hazards to field workers. On the other hand, the drifting of the liquid medicine will cause certain waste. Especially in windy weather, the above shortcomings are more significant, and even normal spraying operations cannot be carried out.

[0003] Theoretically, it is not difficult to solve the above-mentioned existing technical problems by using existing technologies. For example, a windproof mechanism can be set on the spraying component to prevent the droplets from drifting. However, this is not the case in reality. Generally speaking, the support arms of automatic sprayers suitable for large-scale planting are mostly long. In order to improve the maneuverability of the equipment and reduce the occupied space when idle, the support arms often need to adopt a folding design. While taking into account the folding function, the difficulty of setting the windproof mechanism is greatly increased. This is the fundamental reason why the existing automatic sprayers cannot overcome the above-mentioned technical problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the utility model provides a spraying assembly of an automatic sprayer, which includes a support frame formed by multi-dimensional rotating components, on which a flexible cover and a spray head are installed. The shape of the support frame can be adjusted as needed. During the spraying operation, the support frame can be expanded horizontally and together with the flexible cover supported by it, form a protective cover covering the outside of the spray head, thereby reducing the wind dispersion of the atomized liquid medicine. When not in operation, the support frame can be folded on both sides of the equipment to shorten the lateral length, thereby achieving the purpose of reducing the occupied space and improving the maneuverability and flexibility.

[0005] In order to achieve the above technical problems, the utility model adopts the following technical solutions:

[0006] A spraying assembly of an automatic pesticide sprayer, comprising a support frame, a mounting support fixed on the support frame, a plurality of spray heads connected to a liquid supply pipeline fixed in the support frame, characterized in that: the support frame comprises a probe frame and a vertical frame distributed up and down and both in the shape of a frame, the vertical frame and the probe frame are both in a vertical state in the initial state of the support frame; the vertical frame is composed of three sections connected by two first hinged parts along the length direction, and the mounting support is fixed to the front side of a middle section of the vertical frame; the probe frame is composed of three sections connected by two second hinged parts along the length direction, and the three sections of the probe frame and the three sections of the vertical frame are connected up and down Corresponding to each other and respectively connected via the third hinge part, the spray heads are equidistantly fixed on the rear side of the probe frame, the front sides of the vertical frame and the probe frame are covered with a flexible covering cloth, and the upper end of the flexible covering cloth is connected with a pendulum part; a limiting mechanism is provided between the vertical frame and the probe frame; in the initial state of the support frame, the probe frame can rotate backward based on the third hinge part, and maintain in a horizontal state based on the limiting mechanism, at this time, the probe frame is horizontally probing at the upper rear of the vertical frame, and the pendulum part can freely hang down from the rear end of the probe frame; in the initial state of the support frame, the two ends of the vertical frame and the two ends of the probe frame can respectively rotate and move forward horizontally based on the first hinge part and the second hinge part.

[0007] Compared with the prior art, the spraying component of this automatic sprayer has the following beneficial technical effects:

[0008] The spraying assembly of the automatic sprayer has an improved design of the support frame and has added a protective part, a flexible covering cloth. Based on the aforementioned improvements, when performing spraying operations, the position of the probe frame is adjusted so that the probe frame is horizontally extended to the upper rear of the vertical frame. At this time, the spray head is located on the lower side of the probe frame, and the flexible covering cloth and the freely hanging pendulum portion will form a windproof device covering the outside of the spray head to prevent the liquid medicine from being atomized and drifting with the wind, thereby improving the safety of the spraying operation and reducing air pollution and liquid medicine waste. When the spraying operation is not performed, the two ends of the vertical frame and the probe frame are respectively rotated forward so that the two ends of the support frame are abutted against the two sides of the walking device, and the flexible covering cloth is deformed accordingly with the deformation of the support frame, so that the spraying assembly as a whole reaches a folded state, thereby reducing the length of the spraying assembly, improving the maneuverability of the automatic sprayer, and reducing the occupied space when idle.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] This embodiment discloses a specific structure of a spraying assembly of an automatic spraying machine. Figure 1-7 As shown, the spraying assembly includes a support frame, a mounting support 9, a flexible cover cloth 1, a spray head 5 and other main components; the support frame includes a probe frame 4 and a stand frame 6 distributed up and down, and the probe frame 4 and the stand frame 6 are both frame-shaped structures; in the utility model, the support frame adopts a shape-adjustable structure. In order to facilitate the description of the matching relationship between the various components, the initial state of the support frame and the spraying assembly is defined, that is, when the stand frame 6 and the probe frame 4 are both in a vertical state, the support frame and the spraying assembly are in the initial state. In the initial state:

[0024] The stand 6 is composed of three sections along the length direction connected by two first hinges 10, and the rotation axis of the first hinge 10 is located in the vertical direction, so that the two ends of the stand 6 can rotate and move in the horizontal direction, and the mounting bracket 9 is fixed to the front side of the middle section of the stand 6; the probe frame 4 is composed of three sections along the length direction connected by two second hinges 2, and the rotation center axes of the two second hinges 2 are parallel. The three sections of the probe frame 4 correspond one by one to the three sections of the stand 6 and are respectively connected by the third hinge 12, and the rotation center axes of all the third hinges 12 coincide, and the rotation center axes of the third hinges 12 and the second hinges 2 are both Vertically, when the stand 6 and the probe frame 4 are both in a vertical state, each second hinged portion 2 coincides with the rotation center axis of the corresponding first hinged portion 10 located below it, and the spray heads 5 are fixed to the rear side of the probe frame 4 at equal distances along the length direction of the probe frame 4, and the spray heads 5 are connected to the liquid supply pipeline 7; the front sides of the stand 6 and the probe frame 4 are fixedly covered with a flexible covering cloth 1, as the name implies, the flexible covering cloth 1 has a flexible characteristic and can change its shape adaptively with the position change of the stand 6 and the probe frame 4, and the upper end of the flexible covering cloth 1 is connected to a pendulum portion 3; a limiting mechanism for limiting the relative position of the stand 6 and the probe frame 4 is provided between the stand 6 and the probe frame 4;

[0025] See also Figure 8 , 9 As shown in FIG. 10, based on the above structure, in the initial state of the support frame, the probe frame 4 can rotate backward around the third hinge portion 12, and after rotating to a horizontal state, it will maintain a horizontal state based on the action of the limit mechanism. At this time, the spray assembly is in a working state. In this state, the probe frame 4 is horizontally probed at the upper rear of the stand 6, and the pendulum portion 3 can freely hang down from the rear end of the probe frame 4. The flexible cover cloth 1 and the pendulum portion 3 will form a windproof device 15. At this time, the spray head 5 is located at the lower side of the probe frame 4 and is just located in the internal space of the windproof device 15, which can effectively prevent the liquid medicine from being atomized and drifting with the wind;

[0026] See also Fig.11 , 12 As shown, in the initial state of the support frame, the two ends of the upright frame 6 can rotate forward horizontally based on the first hinge portion 10, and at the same time, the two ends of the probe frame 4 can rotate and move synchronously with the two ends of the upright frame 6 based on the second hinge portion 2, thereby allowing the two ends of the support frame to rotate forward as a whole to rest against the two sides of the walking device. At this time, the spray assembly is in a folded state, and the flexible cover cloth 1 and the liquid supply pipeline 7 will deform accordingly with the deformation of the support frame based on their own flexibility.

[0027] like Figure 8-10As shown, when performing pesticide spraying operations, the position of the probe frame 4 is adjusted so that the probe frame 4 is horizontally probed at the upper rear of the vertical frame 6. At this time, the spray head 5 is located at the lower side of the probe frame 4, and the flexible cover cloth 1 and the freely hanging pendulum portion 3 will form a windproof device 15 covering the outside of the spray head 5 to prevent the atomized drug solution from being dispersed by the wind, thereby improving the safety of the pesticide spraying operation and reducing air pollution and waste of drug solution.

[0028] like Fig.11 , 12 As shown, when the spraying operation is not being carried out, the two ends of the vertical frame 6 and the probe frame 4 are respectively rotated forward so that the two ends of the support frame are abutted against the two sides of the walking device, and the flexible covering cloth 1 is deformed accordingly with the deformation of the support frame, thereby reducing the lateral size of the spraying assembly, improving the maneuverability of the automatic sprayer, and reducing the occupied space when idle; in addition, based on the folding principle of the support frame, during actual use, the support frame can also make the two ends rotate and move backward to achieve the expected different degrees of folding.

[0029] When the spraying assembly of the automatic sprayer is implemented, the size and ratio of the stand frame 6 and the probe frame 4 can be adjusted according to the actual operation requirements, in order to ensure that the support frame has good supporting capacity while minimizing the volume after folding. At the same time, Figure 8 , 10 As shown, during the spraying operation, there should be enough space inside the windproof device 15 composed of the probe frame 4, the vertical frame 6 and the flexible cover cloth 1 to ensure that the falling of the liquid medicine sprayed from the spray head 5 will not be hindered, so as to ensure that the liquid medicine can fall to the crop leaves to the greatest extent and improve the spraying effect.

[0030] In the spraying assembly of the above-mentioned automatic pesticide sprayer, the flexible covering cloth 1 should have good waterproof performance to reduce the adsorption of the drug solution, and plastic cloth or canvas is preferably used; the flexible covering cloth 1 and the vertical frame 6 and the probe frame 4 can be fixedly connected by bonding, snaps, etc.; the pendulum part 3 can be a part of the flexible covering cloth 1, and a more preferred method is that the pendulum part 3 and the flexible covering cloth 1 are connected in a combined manner, so that the pendulum part 3 with different drooping sizes can be replaced according to the operational requirements, or the pendulum part 3 can be flexibly replaced according to the wear of the pendulum part 3. The specific connection method between the pendulum part 3 and the flexible covering cloth 1 can be implemented by existing methods such as Velcro 13 and snaps.

[0031] See also Figure 5 , 6As shown, in the spraying assembly of the above-mentioned automatic sprayer, a limiting mechanism is provided between the vertical frame 6 and the probe frame 4. Based on the working principle of the technical solution, the main operation of the limiting mechanism is to limit and maintain the probe frame 4 in a horizontal state; based on the setting intention, the limiting mechanism has a variety of implementation methods; for example, the limiting mechanism is a supporting portion 11 fixed on the vertical frame 6, and the probe frame 4 is rotated downward to a horizontal state and abuts against the supporting portion 11, and the supporting portion 11 provides a supporting effect and cannot continue to rotate downward. At the same time, the probe frame 4 has a tendency to rotate downward due to its own gravity, thereby ensuring that the probe frame 4 can stably maintain a horizontal state during operation.

[0032] See also Figure 4 , 5 As shown in FIG. 6 , in the spray assembly of the automatic pesticide sprayer, a limit frame 14 is fixed on the vertical frame 6. When the probe frame 4 is rotated upward to a vertical state, it abuts against the limit frame 14 and cannot continue to rotate backward. Therefore, the vertical frame 6 and the probe frame 4 can be adjusted to the initial position more efficiently.

[0033] See also Figure 6 , 11 As shown in Figure 12, in the spraying assembly of the above-mentioned automatic sprayer, a locking bolt 8 is installed on the first hinge part 10 or the second hinge part 2. The locking action provided by the locking bolt 8 can prevent the two ends of the vertical frame 6 and the probe frame 4 from rotating horizontally, thereby improving the structural stability of the support frame during the spraying operation and in the folded state.

[0034] The above is a specific description and implementation method of the utility model. Certain changes can be made in combination with the prior art within the scope of the claims, and such changes do not depart from the scope of protection of this patent.

[0035] The various technical features disclosed in this specification and the drawings can be used alone or in combination with the prior art without affecting the beneficial effects of the technology. The implementation method disclosed in the specification is only a preferred embodiment, not all implementation methods, and therefore does not constitute a limitation on the scope of protection claimed in this application.
