Description

Technical Field

[0001] The invention relates to a pump body assembly, in particular to a pump body mounting mechanism and accessories thereof. Background Art

[0002] Unmanned spraying operation is achieved through remote control or navigation, and can spray pesticides, seeds, powders, etc. It can greatly reduce manual labor.

[0003] In a traditional spraying device, the pumps used for spraying are usually multiple and form a pump group. The whole is fixed with bolts. After the pump group is installed, it is difficult to disassemble a single pump separately, and the pump group usually needs to be removed as a whole. When a single pump needs to be inspected and maintained, disassembly and assembly are difficult, and the inspection and maintenance work efficiency is low. When adjusting the number of pumps required for the spraying operation, due to the difficulty in disassembly, the entire pump group can only be carried out for operation, which will waste power system resources. In addition, some of the spraying operations in the prior art are carried out on the ground and some are carried out in the air. When the spraying operation is carried out in the air, the pump body will shake during the process of changing direction, accelerating and decelerating, and the shaking will affect the stability of the spraying operation, and there is a risk of crashing in severe cases.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to be improper limitations of the present invention.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0049] like Figure 1 —10. A pump body mounting mechanism comprises a pump frame 5, a pump body, and a limit assembly 8. At least one of the pump bodies is mounted on the pump frame.

[0050] At least one limiting assembly 8 is disposed between each pump body and the pump frame 5 to limit the horizontal and vertical displacement of the pump body on the pump frame.

[0051] The limiting assembly 8 includes a convex part, a concave part, and a rubber part. The convex part and the concave part are plugged or sleeved with each other.

[0052] The rubber component is located between the concave component and the convex component, and the rubber component enables the concave component and the convex component to be interference-fitted.

[0053] In the present invention, the installation of the pump assembly is achieved through a limiting assembly, and the concave parts and the convex parts are plugged or sleeved together to achieve horizontal or vertical limiting. At the same time, rubber parts are used to make them tightly interference fit, ensuring that the concave parts and the convex parts of the pump body will not fall off during the movement, thereby ensuring the stability of the pump body connection.

[0054] In addition, the use of rubber parts can also reduce the vibration of the pump body and reduce the fluctuation of the pump body.

[0055] There is no limitation on the location of the convex and concave parts. In actual use, they are arranged on the pump body or the pump frame according to the connection space and the structure of the pump body and the pump frame.

[0056] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments: the rubber member is annular, and a groove 8 is circumferentially provided on the outer ring of the rubber member, and the groove is circumferentially matched and connected with the recessed member.

[0057] The use of rubber parts provides a reliable shock absorption effect, and also makes the connection between the concave and convex parts tighter and more reliable. The rubber parts increase the tightness of the pump body in the vertical and horizontal directions, and it cannot move easily. At the same time, vibration absorption provides better shock absorption effect and connection security.

[0058] The number of limit components is set according to actual use needs, and the position is also selected according to actual conditions.

[0059] like Figure 1 As shown in the attached Figure 1 Two pump bodies are symmetrically mounted on the pump frame 5, which are the first pump body 1 and the second pump body 2. A connecting portion is extended up and down in the middle of the pump frame 5, and a connecting through hole is arranged on the connecting portion for connecting to the mobile body.

[0060] The pump body has a horizontal water inlet 3 and a vertical water outlet 4. Here, the portion used for connection on the pump frame 5 protrudes forward from the connecting portion of the pump frame, which is more convenient for installation and removal of the pump body.

[0061] Here, two limit assemblies are arranged between each pump body and the pump frame, including a first limit assemblies and a second limit assemblies; the first limit assemblies enable the pump body and the pump frame to be vertically socketed, so that the pump body has no displacement in the horizontal direction and at least limits the displacement in one direction in the vertical direction (there is no displacement at all in the vertical direction; or there is only upward displacement, and the vertical displacement is used for the installation and disassembly of the pump body).

[0062] The second limiting component enables the pump body to be plugged into the pump frame so that the pump body has no displacement in the horizontal direction and at least limits displacement in one direction in the vertical direction (there may be no displacement at all in the vertical direction; or there may only be upward movement, and the vertical displacement is used for installation and disassembly of the pump body).

[0063] In the attached Figure 1 The upper vertical direction is along direction A; the horizontal direction is along direction B; when the pump body is installed, it is first suspended vertically, and then locked in the horizontal direction due to the interference fit of the rubber parts, thereby achieving the function of common limit locking in two directions without the need for additional locking structure.

[0064] In some embodiments, the installation direction of the pump body is from top to bottom, relying on the gravity of the pump body itself to achieve vertical limitation, and also relying on the friction of the rubber parts to prevent the pump body from jumping in the vertical direction relative to the pump frame; therefore, the pump body can be installed on the pump frame in a "hanging" manner; this method is very convenient for installation and disassembly.

[0065] In addition, according to actual use requirements, the first limiting component or the second limiting component in the above embodiment can be omitted to simplify the structure.

[0066] In some embodiments, the installation direction of the pump body can be first from top to bottom (first limit assembly), and then inserted horizontally from front to back (second limit assembly, where the second rubber part will deform when inserted horizontally, and then recover after insertion); the whole relies on the gravity of the pump body itself to achieve vertical limit, and the horizontal direction relies on interference fit limit. Although this method will increase the difficulty during disassembly due to interference fit, it can achieve the displacement limit of the pump body in both vertical directions by the second limit assembly, and the installation is more stable, secure and safe.

[0067] When the spraying assembly of the device is in operation, the first limit assembly is clamped downward by gravity in the vertical direction due to the gravity of the pump body. When subjected to bumps, the vertical displacement restricted by the second limit assembly will prevent the pump body from moving. Similarly, in the horizontal direction, due to the gravity of the pump body, the first limit assembly is securely locked, and the pump body and the pump frame are tightly connected. Also due to the gravity of the pump body, the second limit assembly cannot be completely separated from the pump frame. The overall structure can be quickly installed and disassembled without bolts, and the connection is reliable and stable, making it safe to use.

[0068] The setting position of the first limiting component on the pump frame is higher than the setting position of the second mounting component; thus, the gravity of the pump body can be fully utilized for locking in both directions, and the structure is ingenious and the conception is novel.

[0069] like Figure 2 — Fig.10As shown, a preferred structure of a limiting component is provided below, wherein the first limiting component 6 includes a first protruding part 602, a first concave part 601, and a first rubber part 603, wherein the first protruding part 602 is arranged on the pump frame 5, and the first rubber part 603 is sleeved on the first protruding part 602; the first concave part 601 is arranged on the pump body (the first pump body or the second pump body); the first concave part 601 is vertically sleeved on the outside of the first protruding part 602 to form an interference fit.

[0070] The first concave part 601 is sleeved on the first convex part 602, so that the pump body has no horizontal displacement relative to the pump frame 5, and the pump body cannot move upward in the vertical direction by relying on its own gravity, thereby achieving locking in the vertical direction.

[0071] The use of the first rubber member 603 provides a reliable shock-absorbing effect, and also makes the connection between the first concave member 601 and the first convex member 602 tighter and more reliable. The rubber member increases the tightness of the connection of the pump body in the vertical direction, and it cannot move easily.

[0072] More preferably, the first rubber member 603 is annular, and a groove 8 is provided in the circumferential direction of the outer ring of the first rubber member 603 , and the width of the groove 8 is the same as the thickness of the first recessed member 601 .

[0073] The setting of the groove 8 allows the first rubber member 603 to be engaged with the first concave member 601, so that the first rubber member 603 cannot be separated from the first concave member 601 in the vertical direction, thereby ensuring the tightness of the connection and absorbing the vibration in the vertical direction, providing better shock absorption effect and connection safety.

[0074] More preferably, the first convex part 602 is a columnar part, and the first concave part 601 is an annular part.

[0075] like Figure 5 As shown, the first rubber member 603 is provided with an integral base 6031 , and the base 6031 is located between the first recessed member 601 and the pump frame 5 , filling the space between the first recessed member 601 and the pump frame 5 .

[0076] This can effectively ensure the shock-absorbing effect between the pump body and the bracket, and also avoid the first recessed part 601 having a suspended space relative to the pump frame 5, so that the connection between the first recessed part 601 and the pump frame 5 is tighter and safer.

[0077] like Figure 2 — Fig.10As shown, in this embodiment: the second limiting assembly includes a second convex part 702, a second concave part 701, and a second rubber part 703, the second convex part 702 is arranged on the pump body, and the second rubber part 703 is sleeved on the second convex part 702; the second concave part 701 is arranged on the pump frame 5, and the second convex part 702 is inserted into the second concave part 701 to form an interference fit.

[0078] The second protrusion 702 is inserted into the second recessed part 701, which ensures that the pump body cannot move or displace vertically relative to the pump frame 5. Due to the gravity of the pump body itself, the lower surface of the second protrusion 702 and the lower surface of the second recessed part 701 have a positive pressure from the gravity of the pump body, which increases friction and hinders the horizontal displacement of the pump body to a certain extent. Combined with the use of the first limit assembly, the overall connection is reliable and stable, and disassembly and assembly are fast.

[0079] like Figure 4 As shown, the use of the second rubber member 703 provides a reliable shock-absorbing effect, and also makes the connection between the second concave member 701 and the second convex member 702 tighter and more reliable. The rubber member increases the tightness of the vertical connection of the pump body, which prevents it from moving easily; it also increases the friction in the horizontal direction, further preventing horizontal movement.

[0080] Further: the second convex part 702 is a second column part, and the end of the second column has a blocking piece 7021; the second concave part is a second annular part. The second convex part with the blocking piece ensures that it has a limit position with the rubber part in the horizontal direction to avoid separation from the rubber part.

[0081] like Figure 3 , Figure 6 Further: an opening 7011 is provided on the upper part of the second annular member, so that the second concave member forms a semi-annular member with the opening facing upward.

[0082] This makes it easy to install and disassemble when combined with the first limiting component; in addition, the blocking piece of the second protrusion can be made larger, and together with the rubber member, the horizontal displacement can be limited, making the connection safer and more reliable.

[0083] In addition, Figure 8 , Fig. 9 , Fig.10 The structure of the pump body itself can be used through casting technology, and the pump head of the pump body can be used as the second convex part 702, thereby reducing the overall connection structure, taking measures according to local conditions, and making the structure more ingenious; the first concave part 601 and the pump body can be used as a whole without disassembly.

[0084] In certain embodiments, a spray assembly is disclosed, including a mobile body and a pump assembly, wherein the pump assembly is fixed to the mobile body, the mobile body moves along a specified path to complete spraying, and the pump assembly includes any one of the pump body mounting mechanisms described above.

[0085] Here, the mobile body is at least one of an agricultural drone (such as a plant protection drone), an agricultural spraying vehicle, and a manual spraying device.

[0086] This mounting mechanism is more suitable for agricultural drone operations. The water inlet 3 of the first pump body 1 is connected to the liquid box (or powder box), and the water outlet 4 is connected to the spraying pipe or nozzle. The first water inlet and the first water outlet can be set to a 360° rotatable structure to achieve multi-directional connection and spraying.

[0087] The mounting structure is simple and ingenious. It is vertically mounted from top to bottom, easy to assemble and disassemble, and has good shock absorption. The spray assembly can realize the independent disassembly and assembly of a single pump, has a simple structure, saves resources, and is easy to maintain.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
