Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a mudguard for a micro-tiller made of elastic material. Background Technology

[0002] Mini tillers are powered by small diesel or gasoline engines and are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. When equipped with appropriate implements, they can perform operations such as pumping water, generating electricity, spraying pesticides, and watering. They can also tow trailers for short-distance transportation. Mini tillers can move freely in the fields, making them convenient for users to use and store. They eliminate the problem of large agricultural machinery being unable to enter mountainous fields, making them the best choice for farmers to replace oxen for plowing.

[0003] Traditional mini-tiller mudguards suffer from multiple problems, including poor mud-blocking effect, low structural strength, inconvenient disassembly and maintenance, inflexible angle adjustment, unstable installation, lack of automatic reset function, and easy wear of parts. These problems not only affect the operating efficiency and lifespan of the mini-tiller, but may also pose safety hazards due to mudguard damage or loosening. At the same time, the high maintenance costs also add to the burden on users and make it difficult to meet the needs of complex operating scenarios. Utility Model Content The purpose of this utility model is to provide a mudguard for a micro-tiller made of elastic material. The mudguard avoids mud splashing by the mud guide block, strengthens the mudguard connecting plate by the reinforcing connecting block, and facilitates disassembly and maintenance by the connecting bolt. The second connecting seat, the first rotating rod, the connecting column, the second rotating rod, and the first connecting seat work together to achieve flexible angle adjustment of the mudguard. The fixed connecting block securely installs the mudguard. The reset hydraulic cylinder and the reset hydraulic rod realize the reset of the mudguard. The positioning column reduces movement friction.

[0004] To achieve the above objectives, a mudguard for a micro-tiller made of elastic material is provided, comprising: a mudguard connecting plate; a mud guide block fixedly connected to the inner surface of the mudguard connecting plate; a reinforcing connecting block fixedly connected to the outer surface of the mudguard connecting plate; a connecting fixing plate detachably connected to the reinforcing connecting block via connecting bolts; a second connecting seat fixedly connected to the upper surface of the connecting fixing plate; a first rotating rod rotatably connected to the outer surface of the second connecting seat; a connecting column fixedly connected to the inner surface of the first rotating rod; a second rotating rod rotatably connected to the outer surface of the connecting column; a first connecting seat rotatably connected to one side of the second rotating rod; a fixing connecting block fixedly connected to the lower surface of the first connecting seat; four rotating grooves formed on the rear surface of the fixing connecting block; connecting rotating blocks rotatably connected to the inner surfaces of the four rotating grooves; a fixing connecting seat fixedly connected to the upper surface of the mudguard connecting plate; a reset hydraulic cylinder connected to the outer surface of the fixing connecting seat; a reset hydraulic rod fixedly connected to the output end of the reset hydraulic cylinder; and a positioning column rotatably connected to the interior of the reset hydraulic rod. The positioning column reduces friction between the reset hydraulic rod and other components, ensuring smooth movement and reducing component wear.

[0005] According to the aforementioned elastic material mudguard for a micro-tiller, the lower surface of the connecting rotating block and the mudguard connecting plate are fixedly connected, and the number of connecting bolts is four. The four connecting bolts secure the components from multiple positions, improving the connection's firmness and preventing loosening due to damage to a single bolt.

[0006] According to the aforementioned elastic material mudguard for a micro-tiller, the second rotating rods are symmetrically arranged on the outer surface of the connecting column, and the positioning column is located between the two second rotating rods. This positioning column can act on both rotating rods simultaneously, reducing motion friction and ensuring smooth adjustment or repositioning of the mudguard.

[0007] According to the aforementioned elastic material mudguard for a micro-tiller, the connecting bolts extend into the interior of the reinforcing connecting blocks, and the number of connecting bolts corresponds to the number of reinforcing connecting blocks. This corresponding arrangement ensures that each reinforcing connecting block is secured with sufficient bolts, guaranteeing consistent overall structural strength.

[0008] According to the aforementioned elastic material mudguard for a micro-tiller, the fixed connecting block is located above the mudguard connecting plate, and the position of the connecting fixing plate is parallel to the fixed connecting block. This parallel layout allows for more reasonable force distribution on the relevant connecting components, ensuring coordinated movement of each component.

[0009] According to the aforementioned elastic material mudguard for a micro-tiller, the dimensions of the mud guide block and the mudguard connecting plate are correspondingly set. This corresponding size ensures that the mud guide block completely covers the inner surface of the mudguard connecting plate, maximizing the mud guiding function and improving the mud-blocking effect.

[0010] According to the aforementioned elastic material mudguard for a micro-tiller, the reset hydraulic cylinder is located between the second rotating rod and the mudguard connecting plate. This position allows the hydraulic cylinder to directly act on the second rotating rod when driving the hydraulic rod, reducing power loss and improving reset efficiency.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4This utility model discloses an elastic material mudguard for a micro-tiller, comprising: a mudguard connecting plate 1, with a mud guide block 2 fixedly connected to the inner surface of the mudguard connecting plate 1. The mud guide block 2 guides the mud generated during micro-tiller operation, preventing mud from splashing randomly, and works with the mudguard connecting plate 1 to achieve a preliminary mudguarding effect. A reinforcing connecting block 3 is fixedly connected to the outer surface of the mudguard connecting plate 1. The reinforcing connecting block 3 enhances the structural strength of the mudguard connecting plate 1, improves its resistance to deformation during operation, and ensures the overall stability of the mudguard component. The reinforcing connecting block 3 is detachably connected to a connecting fixing plate 8 via connecting bolts 9. The connecting bolts 9 securely connect the reinforcing connecting block 3 to the connecting fixing plate 8, and facilitate subsequent adjustments to the connecting fixing plate 8 or the reinforcing connecting block 3. For disassembly, repair, or replacement, a second connecting seat 10 is fixedly connected to the upper surface of the connecting fixing plate 8. The second connecting seat 10 provides a mounting support point for the first rotating rod 11, enabling the first rotating rod 11 to rotate stably and ensuring the continuity of movement of subsequent related components. The outer surface of the second connecting seat 10 is rotatably connected to the first rotating rod 11, allowing the first rotating rod 11 to rotate around the second connecting seat 10, providing the possibility for adjusting the position of the connecting column 12, thereby cooperating to achieve the adjustment of the mudguard angle. The inner surface of the first rotating rod 11 is fixedly connected to the connecting column 12, which can connect two symmetrically arranged second rotating rods 13, enabling the second rotating rods 13 to move synchronously and ensuring the symmetry during the mudguard adjustment process. The outer surface of the connecting column 12 is rotatably connected to... The second rotating rod 13 can rotate around the connecting column 12, and works with the first rotating rod 11 to achieve multi-angle adjustment of the mudguard to adapt to different working environments. A first connecting seat 7 is rotatably connected to one side of the second rotating rod 13, providing a transition between the second rotating rod 13 and the fixed connecting block 4, allowing the second rotating rod 13 to move stably in conjunction with the fixed connecting block 4. A fixed connecting block 4 is fixedly connected to the lower surface of the first connecting seat 7, and the fixed connecting block 4 is fixedly connected to the tiller, allowing the entire mudguard structure to be stably installed on the tiller, ensuring the stability of the mudguard during operation. Four rotating grooves 5 are provided on the rear surface of the fixed connecting block 4, providing rotation space for the connecting rotating block 6. Block 6 can rotate smoothly, avoiding jamming during rotation. Connecting rotating blocks 6 are rotatably connected to the inner surfaces of the four rotating slots 5. These connecting rotating blocks 6 can rotate within the rotating slots 5, allowing for flexible adjustment of the mudguard in conjunction with the mudguard connecting plate 1, while also enhancing the overall flexibility of the mudguard. A fixed connecting seat 14 is fixedly connected to the upper surface of the mudguard connecting plate 1. The fixed connecting seat 14 provides a mounting base for the reset hydraulic cylinder 15, ensuring its stable fixation on the mudguard connecting plate 1 and guaranteeing its normal operation. The reset hydraulic cylinder 15 is connected to the outer surface of the fixed connecting seat 14. The reset hydraulic cylinder 15 can drive the reset hydraulic rod 16 to extend and retract, providing power for the reset of the mudguard, allowing it to return to its initial position after adjustment.A reset hydraulic rod 16 is fixedly connected to the output end of the reset hydraulic cylinder 15. Driven by the reset hydraulic cylinder 15, the reset hydraulic rod 16 extends and retracts, and through its cooperation with the positioning pin 17, drives the second rotating rod 13 to move, thereby realizing the reset operation of the mudguard. The positioning pin 17 is rotatably connected inside the reset hydraulic rod 16, and can rotate inside the reset hydraulic rod 16, reducing friction between the reset hydraulic rod 16 and the second rotating rod 13 and ensuring smooth movement of the second rotating rod 13 when the reset hydraulic rod 16 drives it.

[0017] The lower surface of the connecting rotating block 6 is fixedly connected to the mudguard connecting plate 1. This connection method allows the connecting rotating block 6 and the mudguard connecting plate 1 to form an integral whole, enhancing the supporting effect of the connecting rotating block 6 on the mudguard connecting plate 1. Simultaneously, it ensures that the connecting rotating block 6 can synchronously drive the mudguard connecting plate 1 to adjust its angle when rotating. Four connecting bolts 9 are used, which can fix the reinforcing connecting block 3 and the connecting fixing plate 8 from different positions, making the connection more secure and preventing loosening due to damage to a single bolt. The second rotating rod 13 is symmetrically arranged on the outer surface of the connecting column 12. The rotating rod 13 ensures even force distribution on both sides of the mudguard, guaranteeing consistent movement during mudguard adjustment and preventing tilting. The positioning pin 17 is located between the two second rotating rods 13. This position allows the positioning pin 17 to contact both second rotating rods 13 simultaneously, ensuring the reset hydraulic rod 16 synchronously drives the two second rotating rods 13, improving the synchronicity of mudguard adjustment. The connecting bolt 9 extends into the interior of the reinforcing connecting block 3. This extension increases the contact area between the connecting bolt 9 and the reinforcing connecting block 3, resulting in a tighter connection and improved load-bearing capacity. The number of connecting bolts 9 and the reinforcing connecting block 3... The number of connecting blocks 3 is correspondingly set to ensure that each reinforcing connecting block 3 can be connected to the connecting fixing plate 8 by a sufficient number of bolts, ensuring that the connection strength of each reinforcing connecting block 3 is consistent. The fixing connecting block 4 is located above the mudguard connecting plate 1. This position allows the fixing connecting block 4 to provide upward lifting support for the mudguard connecting plate 1 after it is installed on the mini tiller, improving the overall stability of the mudguard connecting plate 1. The position of the connecting fixing plate 8 is parallel to that of the fixing connecting block 4. This parallel arrangement allows the relevant connecting components between the connecting fixing plate 8 and the fixing connecting block 4 (such as the second connecting seat 1) to be connected. The first rotating rod 11 and other components are subjected to more reasonable force, ensuring the coordination of movement of each component. The size of the mud guide block 2 and the mud baffle connecting plate 1 are set to correspond. The corresponding size allows the mud guide block 2 to completely cover the inner surface of the mud baffle connecting plate 1, ensuring the guiding effect of the mud and avoiding mud splashing from the gap due to size mismatch. The reset hydraulic cylinder 15 is located between the second rotating rod 13 and the mud baffle connecting plate 1. This position allows the reset hydraulic cylinder 15 to drive the reset hydraulic rod 16 to act more directly on the second rotating rod 13, reducing the loss in the power transmission process and improving the efficiency of mud baffle reset.

[0018] Working Principle: First, the mudguard is fixedly connected to the tiller via the fixed connecting block 4 to ensure a stable installation. Then, the connecting bolts 9 between the reinforcing connecting block 3 and the connecting fixing plate 8 are checked to ensure they extend into the reinforcing connecting block 3 and are tightly connected, preventing loosening during operation. Based on the operating environment, the first rotating rod 11 is pushed to rotate around the second connecting seat 10, simultaneously moving the connecting column 12. When the connecting column 12 moves, it causes the second rotating rod 13, symmetrically arranged on its outer surface, to rotate around it. One side of the second rotating rod 13 is connected to the fixed connecting block 4 via the first connecting seat 7, thereby adjusting the angle of the mudguard connecting plate 1. During this process, the connecting rotating block 6 rotates synchronously within the four rotating grooves 5 on the rear surface of the fixed connecting block 4, cooperating with the mudguard connecting plate 1 to achieve flexible angle adjustment until the mudguard angle meets the operational requirements. During operation, the displacement sensor on the fixed connecting block 4 monitors its position changes in real time and transmits the signal to the controller for timely control. With the mudguard installed, the mud guide block 2 guides the mud generated during operation, preventing it from splashing randomly. It works in conjunction with the mudguard connecting plate 1 to achieve a mud-blocking effect. If the working environment changes and a fine-tuning of the angle is required, the angle adjustment operation in step 2 can be repeated. The adjustment is completed through the cooperation of the first rotating rod 11, the connecting column 12, and the second rotating rod 13. After the operation is completed, the reset hydraulic cylinder 15 drives the reset hydraulic rod 16 to extend and retract. The positioning column 17 inside the reset hydraulic rod 16 reduces friction, causing the second rotating rod 13 to rotate in the opposite direction around the connecting column 12. Simultaneously, the first rotating rod 11 rotates in the opposite direction around the second connecting seat 10 until the mudguard connecting plate 1 returns to its initial position. During this process, the pressure sensor at the oil outlet of the reset hydraulic cylinder 15 monitors pressure changes and feeds the data back to the controller to ensure a stable reset process. After reset, check the status of each component, paying particular attention to whether the connecting rotating block 6 has returned to its initial position and whether the connecting bolt 9 remains tightly connected. After confirming there are no abnormalities, the mudguard usage process is complete.
