DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0044] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0046] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] Many agricultural equipment must be mounted at a certain height to avoid being obscured by crops and to ensure stable and efficient operation. For example, agricultural IoT sensor devices that can remotely monitor crop conditions must be mounted at a fixed height for accurate monitoring.

[0048] In order not to affect the operation of agricultural machinery in the field, agricultural equipment needs to be installed in the field after the agricultural machinery operations such as plowing, harrowing, and sowing are completed, and it needs to be retrieved before the crops are harvested so that the harvesters can go to the field to harvest.

[0049] Currently, agricultural equipment, such as agricultural IoT sensors, is typically elevated using poles, which are cost-effective and easy to disassemble. However, the poles, when inserted into the soil, are unstable and prone to tipping, impacting the normal operation of the equipment.

[0050] In response to the above situation, the present invention provides an agricultural equipment, which is installed in the ground by adding an underground component. The underground component can provide sufficient lateral support force to the agricultural equipment to offset the lateral force exerted on the agricultural equipment, thereby playing a good anti-dumping role, effectively improving the installation stability of the agricultural equipment, and ensuring the stable operation of the agricultural equipment.

[0051] For details, please refer to Figure 1 The agricultural equipment 10 provided by the embodiment of the present invention includes an equipment body 20, a vertical pole 30 and an underground component 40. The equipment body 20 can be installed on the underground component 40 through the vertical pole 30.

[0052] Among them, the equipment body 20 can be an agricultural Internet of Things sensor, etc., the top end of the pole 30 is used to connect with the equipment body 20, and the bottom end is used to connect with the buried component 40.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 The buried component 40 includes a fixed cylinder 100, a movable rod 200, a movable disk 300, a plurality of leg supports 400 and a plurality of connecting rods 500. The top of the fixed cylinder 100 is used to connect with the bottom end of the vertical rod 30. The fixed cylinder 100 is provided with a first through hole 102. The movable rod 200 is liftably arranged on the fixed cylinder 100 and passes through the first through hole 102. The movable disk 300 is connected to the movable rod 200. Each leg support 400 is rotatably connected to the fixed cylinder 100 at one end. A plurality of connecting rods 500 correspond to the plurality of leg supports 400 one by one. Each connecting rod 500 is rotatably connected to the movable disk 300 at one end and rotatably connected to the corresponding leg support 400 at the other end. When the movable rod 200 is lifted or lowered relative to the fixed cylinder 100, the movable disk 300 is lifted or lowered with the movable rod 200, so as to drive the plurality of leg supports 400 to expand or retract through the plurality of connecting rods 500.

[0054] To install and use the agricultural equipment 10, first, bury the underground assembly 40 in the soil, with its multiple legs 400 extended. Then, mount the equipment body 20 on the top of the upright pole 30. Finally, mount the bottom of the upright pole 30 on the top of the fixing tube 100 of the underground assembly 40. Because the multiple legs 400 are extended in the soil, the underground assembly 40 has a strong anti-tilt function, effectively preventing the upright pole 30 from tipping over, improving the installation stability of the equipment body 20 and ensuring its normal operation.

[0055] In detail, the top of the vertical rod 30 is detachably connected to the equipment body 20, and the bottom of the vertical rod 30 is also detachably connected to the fixing cylinder 100 of the buried component 40, so as to facilitate the assembly and disassembly of the entire agricultural equipment 10. Figure 5 and Figure 6 In order to facilitate the connection between the vertical rod 30 and the fixed tube 100 and to improve the stability of the vertical rod 30 on the fixed tube 100, in this embodiment, a positioning hole (not shown in the figure) is provided at the bottom end of the vertical rod 30, and the outer peripheral surface of the fixed tube 100 is stepped to form an annular positioning surface 118. When the vertical rod 30 is installed on the fixed tube 100, the bottom end surface of the vertical rod 30 is in contact with the positioning surface 118, and the top end of the fixed tube 100 above the positioning surface 118 is located in the positioning hole, thereby achieving the positioning of the vertical rod 30 and the fixed tube 100. The two first mounting screws 50 respectively penetrate the two first mounting through holes 32 of the vertical rod 30 and enter the positioning hole, and are locked into the two first mounting screw holes 104 on the outer wall of the fixed tube 100, thereby achieving a detachable connection between the vertical rod 30 and the fixed tube 100.

[0056] Please refer to Figure 7 and Figure 8 The movable rod 200 can be set on the fixed cylinder 100 in different ways as needed, as long as it can be raised and lowered relative to the fixed cylinder 100. In this embodiment, the movable rod 200 is set on the fixed cylinder 100 in a threaded connection manner. In detail, the movable rod 200 is a screw, which is threadedly connected to the fixed cylinder 100, and the movable disk 300 is axially fixed relative to the screw and can rotate around the axis of the screw. When the screw rotates around its own axis, the screw rises and falls relative to the fixed cylinder 100, and the movable disk 300 rises and falls with the screw, thereby driving the multiple leg supports 400 to expand or retract through the multiple connecting rods 500. The threaded connection method has the characteristics of low cost and easy operation, so that the movable rod 200 can be raised and lowered by rotation, and can be maintained at a preset height with the support force of the thread, so that the multiple leg supports 400 can be expanded or retracted to a certain extent (the extent to which the leg supports 400 are expanded or retracted is determined by the degree of lifting and lowering of the movable rod 200).

[0057] In order to achieve connection with the screw, in this embodiment, the fixed cylinder 100 includes a cylinder body 110 and a nut 120 connected to the cylinder body 110, the first through hole 102 is set in the cylinder body 110, each foot support 400 is rotatably connected to the cylinder body 110 at one end, the bottom end of the vertical rod 30 is connected to the top of the cylinder body 110, the positioning surface 118 is set at the top of the cylinder body 110, and the screw is threadedly connected to the nut 120. In detail, the threaded portion 220 of the screw is threadedly connected to the threaded hole 122 of the nut 120.

[0058] The nut 120 can be arranged at different positions of the barrel 110 in different ways as needed. In this embodiment, the nut 120 is detachably connected to the top of the barrel 110, so as to be connected to and removed from the barrel 110. To improve the installation stability of the nut 120, in this embodiment, a positioning groove 112 is provided at the top of the barrel 110 to position and cooperate with the nut 120. The positioning groove 112 is connected to the first through hole 102.

[0059] For details, please refer to Figure 8 The positioning groove 112 is a stepped groove, which includes a first groove 114 and a second groove 116 that are connected in sequence from top to bottom. The first groove 114 is surrounded by four side walls and a bottom wall. Two of the four side walls are flat, and the other two are curved. The second groove 116 is a cylindrical groove and is opened on the bottom wall of the first groove 114. The end of the second groove 116 away from the first groove 114 is connected to the first through hole 102. The nut 120 includes an integrally formed flange 124 and a connecting column 126. The shape and size of the flange 124 are adapted to the first groove 114, and the shape and size of the connecting column 126 are adapted to the second groove 116. The flange 124 and the connecting column 126 are both provided with threaded holes to form a threaded hole 122 for the nut 120 to be connected to the screw. The flange 124 is positioned and engaged with the first slot 114, and the connecting post 126 is positioned and engaged with the second slot 116, thereby achieving the positioning and engagement of the nut 120 with the positioning slot 112. Four second mounting screws 60 pass through the four second mounting holes 128 in the flange 124 and are then screwed into the four second mounting screw holes 106 in the bottom wall of the first slot 114, thereby securing the nut 120 to the barrel 110. The upper surface of the flange 124 is flush with the top surface of the barrel 110, thereby improving the flatness of the top end of the fixed barrel 100.

[0060] It should be noted that in other embodiments, the nut 120 can also be connected to the top of the cylinder 110 by welding, clamping, etc.; the nut 120 can also be set at the bottom end of the cylinder 110; the nut 120 can also be directly connected to the upper surface of the cylinder 110 without setting the positioning groove 112.

[0061] Please refer to Figure 8, the diameter of the screw is smaller than the first through hole 102, so that there is a preset distance between it and the inner wall of the first through hole 102, thereby ensuring that the screw can rotate freely in the first through hole 102. The length of the screw is greater than the length of the fixed cylinder 100, and the top of the screw is located outside the fixed cylinder 100 to provide a fulcrum for the rotation drive of the screw. In this embodiment, the top of the screw is provided with a flat portion 210 parallel to the axis of the screw. There are multiple flat portions 210 and they are arranged at intervals around the axis of the screw. The provision of the flat portion 210 can facilitate the user to clamp the top of the screw with the help of tools such as pliers to drive the screw to rotate. In other embodiments, the top of the screw can also be provided with a radially extending through hole, so that the user can drive the screw to rotate after drilling the through hole with the help of tools such as steel bars.

[0062] Please refer to Figure 9 and Figure 10 The bottom end of the screw is also located outside the fixed cylinder 100 so as to be connected to the movable disk 300. The movable disk 300 can adopt different structural forms as needed, as long as it can be fixed axially relative to the screw and can rotate around the axis of the screw.

[0063] Please refer to Figure 11 In this embodiment, the movable disc 300 includes a disc body 310 and a nut 320. The disc body 310 is rotatably mounted on the screw, and the nut 320 is threadedly connected to the screw. The screw threaded portion 220 and the nut 320 are located on either side of the disc body 310 to jointly restrict the axial movement of the disc body 310, thereby fixing the disc body 310 axially relative to the screw. Each connecting rod 500 is rotatably connected to the disc body 310 at one end away from the corresponding foot support 400.

[0064] To allow for free relative rotation between the movable disk 300 and the screw, in this embodiment, the disk body 310 is provided with a second through-hole 312 for the screw to pass through. A gap 314 is defined between the inner wall of the second through-hole 312 and the screw. A gap 314 is defined between the top wall of the disk body 310 and the threaded portion 220 of the screw. A gap 314 is defined between the bottom wall of the disk body 310 and the nut 320. The provision of these three gaps 314 effectively reduces the contact area between the disk body 310 and the screw, facilitating relative rotation between the movable disk 300 and the screw. In other embodiments, only one or two of the three gaps 314 may be provided.

[0065] It should be noted that in addition to the threaded connection between the movable rod 200 and the fixed cylinder 100, a sliding connection can also be adopted. With the sliding connection, the fixed cylinder 100 no longer needs to be provided with a nut 120, and the movable disk 300 can be completely fixed to the movable rod 200 and no longer needs to rotate relative to the movable rod 200. The movable rod 200 can be directly raised and lowered relative to the fixed cylinder 100 without rotating around its own axis.

[0066] Please refer to Figure 9 and Figure 10 The end of the connecting rod 500 away from the movable disc 300 is rotatably connected to the inner surface of the middle portion of the leg support 400. The number of connecting rods 500 and leg supports 400 can vary as needed. In this embodiment, the number of connecting rods 500 and leg supports 400 is four. The four connecting rods 500 are evenly spaced around the axis of the fixed cylinder 100 or the movable rod 200. The four leg supports 400 are also evenly spaced around the axis of the fixed cylinder 100. When the four leg supports 400 are in the deployed state, their projections on the horizontal plane form a "cross" shape, thereby improving the support stability of the buried assembly 40 in the soil. In other embodiments, the number of connecting rods 500 and leg supports 400 can also be two, three, or five.

[0067] Please refer to Figure 12 To further enhance the support stability of the in-ground assembly 40 after it is buried in the soil, the surface of the foot support 400 is provided with at least one of a protrusion 410 and a groove 420. The protrusion 410 and groove 420 effectively increase the contact area between the foot support 400 and the soil, thereby improving the support provided by the in-ground assembly 40 to the device body 20.

[0068] In this embodiment, the outer surface of the foot support 400 is provided with multiple protrusions 410 and multiple grooves 420. The multiple protrusions 410 and the multiple grooves 420 are arranged alternately along the length of the foot support 400 to maximize the surface area of ​​the foot support 400, thereby maximizing the contact area with the soil, effectively preventing the foot support 400 from shaking in the soil, and further improving the support stability of the buried assembly 40 in the soil. The cross-sections of the protrusions and grooves 410 are both trapezoidal, where the so-called cross-section refers to the cross-section perpendicular to the length of the foot support 400. In other embodiments, the foot support 400 may be provided with only protrusions 410 or grooves 420, and the cross-sections of the protrusions 410 or grooves 420 may also be rectangular, triangular, semicircular, etc.

[0069] It should also be noted that in this embodiment, the rotational connection between the foot support 400 and the fixed cylinder 100, the rotational connection between the connecting rod 500 and the movable disk 300, and the rotational connection between the connecting rod 500 and the foot support 400 are all pivot connections. In other embodiments, they can also be hinged.

[0070] The working principle and usage of the agricultural equipment 10 are as follows:

[0071] When not in use, the device body 20, the upright pole 30, and the underground assembly 40 are in a disassembled state, wherein the multiple legs 400 of the underground assembly 40 are in a retracted state (refer to Figure 2), the four connecting rods 500 are close to each other and are roughly parallel to the axis of the fixed tube 100 or the movable rod 200, and the four leg supports 400 are also close to each other and are roughly parallel to the axis of the fixed tube 100. At this time, the underground component 40 occupies a small space and is easy to pack in a regular manner to reduce transportation and storage costs.

[0072] When work is required, the underground assembly 40 is first arranged, and the movable rod 200 is driven to rotate forward. Due to the transmission effect of the thread, the movable rod 200 will move downward, thereby driving the movable plate 300 to move downward. During the descent of the movable plate 300, the multiple connecting rods 500 will be driven to move. The ends of the multiple connecting rods 500 away from the movable plate 300 are separated from each other, so that the multiple connecting rods 500 are deployed, thereby driving the ends of the multiple leg supports 400 away from the fixed cylinder 100 to move away from each other, so that the multiple leg supports 400 are deployed (refer to Figure 3 Then dig a pit in the ground to accommodate the underground component 40, place the underground component 40 in the pit and backfill the soil until the underground component 40 is buried in the soil, leaving only the top of the fixing tube 100 exposed above the ground. Finally, install the device body 20 on the top of the vertical pole 30, and connect the top of the vertical pole 30 to the top of the fixing tube 100 (refer to Figure 1 Since the multiple leg supports 400 are in an extended state in the soil, they can provide sufficient lateral support force to the fixing tube 100 in multiple directions, offsetting the lateral force on the upright pole 30 caused by uneven force or lateral wind resistance, playing a good anti-tilting role, effectively preventing the device body 20 from tipping over, improving the installation stability of the device body 20, and thus ensuring the normal operation of the device body 20.

[0073] When the work is completed, first remove the equipment body 20 and the vertical rod 30 from the fixed cylinder 100, and then drive the movable rod 200 to rotate in the opposite direction. Due to the transmission action of the thread, the movable rod 200 will move upward, thereby driving the movable disk 300 to move upward. During the rising process of the movable disk 300, the multiple connecting rods 500 will drive the movement of the multiple connecting rods 500, and the ends of the multiple connecting rods 500 away from the movable disk 300 will approach each other, so that the multiple connecting rods 500 will be retracted, thereby driving the multiple leg supports 400 away from the ends of the fixed cylinder 100 to approach each other, so that the multiple leg supports 400 will be retracted. In the process of retracting the multiple leg supports 400, the protrusions 410 and grooves 420 on the outer surface will be separated from the soil, and the inner surface will squeeze the surrounding soil. Due to the reaction force of the soil, the fixed cylinder 100 will obtain an upward driving force, thereby breaking out of the soil so that it can be easily pulled out of the soil for the next use. Since the fixed cylinder 100 and the movable rod 200 are connected by threads, the movable rod 200 can be raised or lowered relative to the fixed cylinder 100 by simply driving the movable rod 200 to rotate, so the operation is easy and labor-saving.

[0074] The agricultural equipment 10 includes an equipment body 20, a vertical pole 30 and an underground component 40. The underground component 40 includes a fixed cylinder 100, a movable rod 200, a movable disk 300, a plurality of leg supports 400 and a plurality of connecting rods 500. The fixed cylinder 100 is provided with a first through hole 102. The movable rod 200 is liftably arranged on the fixed cylinder 100 and passes through the first through hole 102. The movable disk 300 is connected to the movable rod 200. Each leg support 400 is rotatably connected to the fixed cylinder 100 at one end. The plurality of connecting rods 500 correspond to the plurality of leg supports 400 one by one. Each connecting rod 500 is rotatably connected to the movable disk 300 at one end and rotatably connected to the corresponding leg support 400 at the other end. When the movable rod 200 is lifted or lowered relative to the fixed cylinder 100, the movable disk 300 is lifted or lowered with the movable rod 200, so as to drive the plurality of leg supports 400 to expand or retract through the plurality of connecting rods 500. By adding an underground component 40 to support the equipment body 20, the underground component 40 can play a good anti-tilting role when the multiple leg supports 400 are in the unfolded state and buried in the soil, and can effectively prevent the upright pole 30 from tipping over, thereby improving the installation stability of the equipment body 20 and ensuring the normal operation of the equipment body 20.
