Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective shed equipment technology, and in particular to a protective shed structure for agricultural machinery. Background Technology
[0002] Agricultural machinery is a general term for various mechanical equipment used in agricultural production. It is mainly used for farming and is therefore generally used outdoors. Due to the strong sunlight in summer, a protective canopy structure is usually installed on its top.
[0003] Currently, in practical applications, agricultural machinery protective sheds are mostly designed with a fixed support frame and a lightweight protective shed body as their core form. The fixed support frame is rigidly connected to the top of the agricultural machinery, stably supporting the shed above the operating area. Its main function is to shield against rain, fallen leaves, dust, and other debris, preventing them from falling directly onto the user and providing basic protection for agricultural machinery operators. However, this "fixed" structural design has significant drawbacks: because the connection between the support frame and the shed body cannot be adjusted (e.g., welding, bolted connections), the shed body always remains horizontal or at a fixed tilt angle, making it extremely difficult to clean the debris accumulated on the roof. In actual operation, the roof easily accumulates rain-soaked fallen leaves, sticky mud, crop straw fragments, and other debris. These debris... Because the canopy cannot be rotated or tilted, it is difficult to clean. Some corners even require users to climb ladders to operate, which is not only time-consuming and laborious, but also poses a safety hazard of falling from height. Faced with such cleaning problems for a long time, users are prone to "laziness" or "giving up on cleaning", which leads to the continuous accumulation of debris on the canopy roof. As the weight of the accumulated debris gradually increases, the connection between the thin canopy body (mostly made of PVC, canvas and other materials) and the fixed support will be subjected to pressure exceeding the design standard for a long time. The initial manifestation is loosening of the seams at the connection points and deformation of bolt holes. Later, serious damage such as tearing of the canopy edges and detachment of the support from the canopy body will occur, directly causing the protective function of the canopy to fail, seriously affecting the work efficiency and user experience, and reducing users' satisfaction with agricultural machinery equipment.
[0004] Therefore, a protective shed structure for agricultural machinery is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a protective canopy structure for agricultural machinery, aiming to solve the problem that current agricultural machinery protective canopies in practical applications mostly adopt a core design of fixed brackets + thin protective canopy body. Through the rigid connection between the fixed brackets and the top of the agricultural machinery, the canopy body is stably supported above the operating area, mainly serving to shield against rainwater, fallen leaves, dust, and other debris, preventing debris from falling directly onto the user and providing basic protection for agricultural machinery operators. However, this "fixed" structural design has significant drawbacks: because the connection method between the brackets and the canopy body cannot be adjusted (such as welding fixation, bolted fixed connection, etc.), the canopy body always remains horizontal or at a fixed tilt angle, making it extremely difficult to clean the accumulated debris on the canopy roof. In actual operation, the canopy roof easily accumulates fallen leaves soaked by rainwater, sticky mud, and other debris. Straw fragments and other debris are difficult to clean because the shed cannot be rotated or tilted. In some corners, users even need to climb ladders to reach them, which is time-consuming, laborious, and poses a safety hazard of falling from height. Faced with such cleaning problems for a long time, users are prone to "laziness" or "giving up on cleaning," causing debris to accumulate on the shed roof. As the weight of the accumulated debris gradually increases, the connection between the thin shed body (mostly made of PVC, canvas, etc.) and the fixed support will be subjected to pressure exceeding the design standard for a long time. Initially, this manifests as loose seams at the connection points and deformation of bolt holes. Later, serious damage such as tearing of the shed edges and detachment of the support from the shed body will occur, directly causing the protective function of the shed to fail, seriously affecting work efficiency and user experience, and reducing user satisfaction with agricultural machinery equipment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective canopy structure for agricultural machinery, comprising an agricultural machinery support rod body, a shielding mechanism being provided at the top of the agricultural machinery support rod body, the shielding mechanism comprising a support component and an adjustment component, the support component being disposed at the top of the agricultural machinery support rod body, the adjustment component being disposed inside the support component, the support component comprising a bearing rod, a connecting block, a bearing frame, and a protective canopy, the bearing rod being movably connected to the inside of the agricultural machinery support rod body, the connecting block being fixedly connected to the top of the bearing rod, the bearing frame being bolted to the top of the connecting block, and the protective canopy being rotatably connected to the top of the bearing frame.
[0007] Preferably, the adjustment assembly includes a storage channel bolted to the inner side of the agricultural machinery support rod body, a drive rod rotatably connected to the bottom of the inner side of the storage channel, a movable ring threadedly connected to the surface of the drive rod, and the surface of the movable ring rotatably connected to the bottom of the inner side of the support rod.
[0008] Preferably, a movable channel is provided on the right side of the storage channel, and an extension shed is slidably connected to the inner side of the movable channel.
[0009] Preferably, a threaded hole is provided on the inner side of the moving channel, and a friction positioning rod is threadedly connected to the inner side of the moving channel.
[0010] Preferably, an auxiliary component is provided on the inner side of the agricultural machinery support rod body. The auxiliary component includes a rotating handle fixedly connected to the bottom of the drive rod. A slider is provided on the top of the rotating handle, and the surface of the slider is slidably connected to both sides of the inner side of the storage channel.
[0011] Preferably, cavities are provided on both the front and rear sides of the inner side of the slider, and rollers are rotatably connected to both the front and rear sides of the inner side of the slider.
[0012] Preferably, the inner side of the bearing rod is provided with a cavity, and the connecting block is a rotatable structure, with its top fixedly connected to the left side of the bottom of the protective shed.
[0013] Preferably, the inner side of the support frame is provided with a storage hole, and a limit rod is fixedly connected to the left side of the bottom of the protective shed.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application achieves flexible adjustment and stable support of the protective canopy angle by setting up a support component. When using this agricultural machinery protective canopy structure, the bearing rod in the support component is movably connected to the inner side of the agricultural machinery support rod body, providing a liftable support foundation for the overall canopy body; the connecting block is fixed to the top of the bearing rod, which has both rigid connection and rotatable characteristics, which can not only stably connect the bearing rod and the protective canopy, but also provide rotation space for the adjustment of the protective canopy angle; the bearing frame is bolted to the top of the connecting block, and the protective canopy is rotatably connected to the top of the bearing frame, which can be flipped around the connection point. When it is necessary to clean the accumulated materials on the canopy top, there is no need to climb up to operate. By simply adjusting the tilt angle of the protective canopy, the fallen leaves, soil and other debris can be automatically slid off by gravity, which greatly reduces the cleaning difficulty and safety hazards; during daily operation, the protective canopy can be adjusted to a horizontal or suitable tilt angle to ensure effective shielding of the operator, while avoiding local water and debris accumulation problems caused by the fixed angle of the canopy body, thus extending the service life of the protective canopy; 2. This application, by setting up an adjustment component, meets the requirements for expanding the protection range and adapting the height. The storage channel bolt in the adjustment component is fixed to the inner side of the agricultural machinery support rod, providing a stable storage and movement space for the drive rod and the load-bearing rod. The drive rod is rotatably connected to the bottom of the storage channel, and its surface thread cooperates with the moving ring. By rotating the drive rod, the moving ring can be driven to rise and fall along the drive rod axis, thereby pushing the load-bearing rod to rise and fall synchronously, realizing the lifting of the left side of the protective canopy. An extension canopy is slidably connected to the inner side of the moving channel on the right side of the storage channel. When the operating width of the agricultural machinery increases or the coverage area needs to be expanded, the extension canopy can be pulled out from the moving channel to extend the lateral coverage area of the protective canopy. The threaded hole on the inner side of the moving channel cooperates with the friction positioning rod. After the extension canopy is pulled out, the friction positioning rod is tightened so that its end is in close contact with the surface of the extension canopy. The position of the extension canopy is fixed by friction, preventing the extension canopy from sliding during operation and ensuring that the expanded protection range is stable and reliable.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5A protective canopy 214 structure for agricultural machinery includes an agricultural machinery support rod body 1. A shielding mechanism 2 is provided on the top of the agricultural machinery support rod body 1. The shielding mechanism 2 includes a support component 21 and an adjustment component 22. The support component 21 is located on the top of the agricultural machinery support rod body 1, and the adjustment component 22 is located inside the support component 21. The support component 21 includes a bearing rod 211, a connecting block 212, a bearing frame 213, and a protective canopy 214. The bearing rod 211 is movably connected to the inside of the agricultural machinery support rod body 1. The connecting block 212 is fixedly connected to the top of the bearing rod 211. The bearing frame 213 is bolted to the top of the connecting block 212. The protective canopy 214 is rotatably connected to the top of the bearing frame 213.
[0019] In this embodiment: by setting up a support rod 211, a connecting block 212, a support frame 213, and a protective canopy 214, the support rod 211 is installed on the top of the adjustment assembly 22. At this time, the support rod 211 is at the top of the agricultural machinery support rod body 1, while the support frame 213 is directly installed on the top of the agricultural machinery support rod body 1. At this time, the connecting block 212 can be fixedly installed on the top of the support rod 211. The top of the support frame 213 is rotatably connected to the protective canopy 214. The bottom left side of the protective canopy 214 is fixedly connected to the top of the connecting block 212. At the same time, the inner side of the connecting block 212 itself has a rotatable connection, so that when the support rod 211 is raised and lowered inside the adjustment assembly 22, the connecting block 212 can cooperate with the support rod 211 to raise the left side of the protective canopy 214, ensuring that the protective canopy 214 can be raised to a left-high-right-low state, which is convenient for users to clean.
[0020] Specifically, such as Figure 2 , Figure 4 As shown, the adjustment assembly 22 includes a storage channel 221 bolted to the inside of the agricultural machinery support rod body 1. A drive rod 222 is rotatably connected to the bottom of the inside of the storage channel 221. A moving ring 223 is threadedly connected to the surface of the drive rod 222. The surface of the moving ring 223 is rotatably connected to the bottom of the inside of the bearing rod 211.
[0021] Specifically, such as Figure 2 , Figure 4 As shown, a moving channel 224 is provided on the right side of the storage channel 221, and an extension shed 225 is slidably connected to the inner side of the moving channel 224.
[0022] Specifically, such as Figure 2 , Figure 4 As shown, a threaded hole is provided on the inner side of the moving channel 224, and a friction positioning rod is threadedly connected to the inner side of the moving channel 224.
[0023] In this embodiment: By setting up a storage channel 221, a drive rod 222, a moving ring 223, a moving channel 224, and an extension shed 225, the height of the protective shed 214 is adjusted: the operator manually rotates the rotating handle 31 in the auxiliary component 3, and the rotating handle 31 drives the drive rod 222 inside the storage channel 221 to rotate synchronously. Since the thread on the surface of the drive rod 222 is threadedly connected to the moving ring 223, and the moving ring 223 is rotatably connected to the bottom inner side of the bearing rod 211, when the drive rod 222 rotates, the moving ring 223 moves upward along the axial direction of the drive rod 222. The downward movement pushes the support rod 211 to rise and fall inside the agricultural machinery support rod body 1. During this process, the slider 32 moves synchronously with the support rod 211, and its surface slides in cooperation with the inside of the storage channel 221. At the same time, the roller 33 inside the slider 32 rolls to reduce friction, ensuring that the support rod 211 rises and falls smoothly until the protective shed 214 is adjusted to a suitable height. The angle adjustment and cleaning of the protective shed 214: When the top of the shed is piled with fallen leaves, soil and other debris and needs to be cleaned, continue to fine-tune the drive rod 222 by rotating the handle 31 to make the support rod 211 rise slightly. Since the connecting block 212 is fixed to the top of the bearing rod 211 and connected to the bottom left side of the protective canopy 214, when the bearing rod 211 rises, it pushes the left side of the protective canopy 214 upward, while the right side of the protective canopy 214 is rotatably connected to the top of the bearing frame 213. At this time, the protective canopy 214 tilts around the right connection point, forming a tilt angle from left to right. The accumulated material automatically slides down the tilted canopy top under the action of gravity. After cleaning is completed, the reverse rotation of the drive rod 222 causes the bearing rod 211 to descend, and the protective canopy 214 returns to a horizontal or suitable tilted state for operation. The storage hole on the inner side of the bearing frame 213 and the limit at the bottom of the protective canopy 214 are then connected. The lever mechanism limits excessive tilting of the protective canopy 214, ensuring structural stability and expanding the protection range: When the operating width of the agricultural machinery increases and the shielding range needs to be expanded, the extension canopy 225 inside the moving channel 224 is pulled outward, allowing the extension canopy 225 to slide along the moving channel 224 to the required length. Then, the friction positioning rod inside the moving channel 224 is tightened, so that the end of the friction positioning rod is in close contact with the surface of the extension canopy 225. The position of the extension canopy 225 is fixed by friction, preventing slippage during operation. After the operation is completed, the extension canopy 225 can be retracted into the moving channel 224 by reversing the operation, reducing the space occupied by the device.
[0024] Specifically, such as Figure 5 As shown, an auxiliary component 3 is provided on the inner side of the agricultural machinery support rod body 1. The auxiliary component 3 includes a rotating handle 31 fixedly connected to the bottom of the drive rod 222. A slider 32 is provided on the top of the rotating handle 31. The surface of the slider 32 is slidably connected to both sides of the inner side of the storage channel 221.
[0025] Specifically, such as Figure 5 As shown, cavities are provided on the front and rear sides of the inner side of the slider 32, and rollers 33 are rotatably connected to the front and rear sides of the inner side of the slider 32.
[0026] In this embodiment: by setting a rotating handle 31, a slider 32, and a roller 33, the rotating handle 31, slider 32, and roller 33 cooperate with each other. The rotating handle 31 is installed at the bottom of the drive rod 222, making it convenient for the user to rotate the drive rod 222. Under the action of the thread, the moving ring 223 moves up and down on the surface of the drive rod 222, thereby driving the bearing rod 211 to move up and down. The bearing rod 211 drives the connecting block 212 and the protective canopy 214 to move up and down. Since the connecting block 212 itself can rotate and bend, and in conjunction with the bottom of the protective canopy 214... The right side is rotatably connected to the top right side of the support frame 213, so that the support rod 211 can be lifted upward from the bottom left side of the protective shed 214. At this time, the protective shed 214 can be raised from the left side, so that its surface is tilted from left to right. The slider 32 and the roller 33 are installed on both sides of the support rod 211. At the same time, the slider 32 and the roller 33 are slidably connected to the inside of the storage channel 221, so that the slider 32 and the roller 33 can be used as a guide structure for the support rod 211, ensuring that the support rod 211 can move up and down inside the storage channel 221.
[0027] Specifically, such as Figure 3 As shown, the inner side of the bearing rod 211 has a cavity, and the connecting block 212 is a rotatable structure, with its top fixedly connected to the left side of the bottom of the protective shed 214.
[0028] Specifically, such as Figure 3 As shown, the inner side of the support frame 213 has a storage hole, and the left side of the bottom of the protective shed 214 is fixedly connected with a limit rod.
[0029] In this embodiment: by setting up a support rod 211, a connecting block 212, a support frame 213, and a protective canopy 214, the support rod 211, the connecting block 212, the support frame 213, and the protective canopy 214 cooperate with each other. The support rod 211 can be raised and lowered under the action of the adjusting component 22. The internal structure of the connecting block 212 is a rotatable connection, so that it is located between the support rod 211 and the protective canopy 214 as a connecting structure, which facilitates the support rod 211 to drive the left side of the protective canopy 214 to be raised. The top of the support frame 213 is rotatably connected to the top right side of the protective canopy 214 to assist the protective canopy 214 in being raised. The support frame 213 can also support and restrict the protective canopy 214.
[0030] Working Principle: First, this device provides sunshade, rain protection, and protection from falling debris for operators during agricultural machinery operations. When using the agricultural machinery protective canopy 214 structure, initial adjustments must be made according to the agricultural machinery operation scenario and the operator's needs: Height adjustment of the protective canopy 214: The operator manually rotates the rotating handle 31 in the auxiliary component 3. The rotating handle 31 drives the drive rod 222 inside the storage channel 221 to rotate synchronously. Because the thread on the surface of the drive rod 222 is threadedly connected to the moving ring 223, and the moving ring 223 is rotatably connected to the bottom inner side of the bearing rod 211, when the drive rod 222 rotates, the moving ring 223... The moving ring 223 moves up and down along the axial direction of the drive rod 222, thereby pushing the bearing rod 211 to rise and fall inside the agricultural machinery support rod body 1. During this process, the slider 32 moves synchronously with the bearing rod 211, and its surface slides in cooperation with the inner side of the storage channel 221. At the same time, the roller 33 inside the slider 32 rolls to reduce friction, ensuring that the bearing rod 211 rises and falls smoothly until the protective shed 214 is adjusted to a suitable height. Angle adjustment and cleaning of the protective shed 214: When fallen leaves, soil, and other debris accumulate on the shed roof and need to be cleaned, continue to fine-tune the drive rod 222 by rotating the handle 31 to slightly raise the bearing rod 211. Due to the connection... Block 212 is fixed to the top of the support rod 211 and connected to the bottom left side of the protective canopy 214. When the support rod 211 rises, it pushes the left side of the protective canopy 214 upward, while the right side of the protective canopy 214 is rotatably connected to the top of the support frame 213. At this time, the protective canopy 214 tilts around the right connection point, forming a tilt angle from left to right. The accumulated material automatically slides down the tilted canopy roof under the action of gravity. After cleaning is completed, the drive rod 222 is rotated in the opposite direction to lower the support rod 211, and the protective canopy 214 returns to a horizontal or tilted state suitable for operation. The storage hole on the inner side of the support frame 213 matches the limiting rod at the bottom of the protective canopy 214. To limit excessive tilting of the protective canopy 214 and ensure structural stability, the protection range is expanded: When the operating width of the agricultural machinery increases and the shielding range needs to be expanded, the extension canopy 225 inside the moving channel 224 is pulled outward, allowing the extension canopy 225 to slide along the moving channel 224 to the required length. Then, the friction positioning rod inside the moving channel 224 is tightened, so that the end of the friction positioning rod is in close contact with the surface of the extension canopy 225. The position of the extension canopy 225 is fixed by friction, preventing slippage during operation. After the operation is completed, the extension canopy 225 can be returned to the moving channel 224 by reversing the operation, reducing the space occupied by the device.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the present utility model should be included within the protection scope of the present utility model.
