Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy engineering technology, specifically to a ditching device for farmland water conservancy engineering. Background Technology

[0002] Farmland irrigation projects are an important part of agricultural infrastructure construction. They refer to various engineering construction and management activities carried out to improve farmland water conditions and enhance agricultural productivity. Their core objectives are to ensure the water needs of crops, improve land utilization and crop yield. To achieve these objectives, it is necessary to carry out the engineering construction process of digging various ditches according to design requirements. These ditches are mainly used for irrigation, drainage, flood control, fertilization and field management.

[0003] Ditching devices are specialized mechanical equipment used in farmland water conservancy projects to dig ditches. They mainly achieve water conservancy functions such as irrigation, drainage, and fertilization through efficient and precise digging operations. However, existing ditching devices typically use fixed mechanical connections, such as bolts or pins, for tool replacement. This means that when the tools are worn or broken, operators need to use tools to replace them, making it difficult to manually disassemble and install them, which affects the efficiency of ditching operations.

[0004] Meanwhile, existing excavation equipment usually connects the excavator to the tractor through a simple connecting device. However, traditional connection methods often lack sufficient strength and flexibility, and are prone to loosening, misalignment, or excessive vibration due to external forces or uneven ground during operation. This can lead to loosening or detachment of the connection during trenching operations, making it impossible to stably transmit traction force and resulting in a decrease in trenching accuracy.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a ditching device for farmland water conservancy projects to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A ditching device for farmland irrigation projects, comprising:

[0009] The connecting bracket and drive connector are used for connection to the tractor unit;

[0010] The fastening assembly is located at the connection between the connecting frame and the tractor vehicle to achieve a tight fastening between the connecting frame and the tractor vehicle.

[0011] The drive control box, located at one end of the drive connector, is used to control the operation of trenching work;

[0012] Limit brackets are installed on both sides of the connecting bracket;

[0013] The trenching components are located on both sides of the drive control box;

[0014] Several cutterhead maintenance components are located inside the trenching component;

[0015] The top of the drive control box is equipped with a soil discharge baffle, and the bottom of the soil discharge baffle is equipped with a soil lifting plate.

[0016] Furthermore, to achieve precise connection between the tractor and the trenching device, a double locking mechanism using a drop pin and a positioning pin transmits stable traction force, ensuring that the trenching device will not disengage due to external forces during operation. This prevents the trenching device from becoming loose or detached during trenching operations. The automatic coupling and mechanical locking features enable rapid docking between the tractor and the trenching device, reducing the time and effort required for manual connection. The fastening assembly includes a connecting rod that connects to the connecting frame and the tractor. The connecting rod has a first through hole and a second through hole inside. A drop pin is installed inside the first through hole, and a positioning pin is installed inside the second through hole. The positioning pin has a hook inside. The connecting rod also has a cavity for installing the drop pin.

[0017] Furthermore, in order to enable the trenching blades to rotate at high speed and cut into the farmland soil by driving the rollers through the rotating shaft, and to achieve trenching by utilizing the cutting force of the trenching blades, the trenching assembly includes a rotating shaft controlled by a drive control box, rollers are provided on both sides of the rotating shaft, and several trenching blades are provided on the outer side of the rollers through a cutter head maintenance assembly.

[0018] Furthermore, to enable rapid replacement of the trenching blades through the cooperation of the compression spring and the insert rod, allowing for quick replacement when the trenching blades are worn or cracked, thus avoiding prolonged interruptions to the overall trenching operation due to blade maintenance, and to flexibly change the appropriate trenching blade specifications according to different farmland soil types, trenching depths, and widths, thereby enhancing the versatility of the trenching device in farmland irrigation projects, the cutter head maintenance component includes a third and fourth through hole inside the roller and the trenching blade; a limit block is set inside the third through hole, and an insertion cavity is set inside the limit block, with a sliding cavity inside the insertion cavity; a sliding block is set inside the sliding cavity, and an insert rod is sleeved in the middle of the sliding block, with a compression spring at the top of the insert rod, and a pressing block is set at the top of the compression spring inside the limit block; a stop block that cooperates with the sliding block is set inside the pressing block.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model has a simple structure and is easy to operate. By setting up a ditching component, the ditching blade can be rotated at high speed by a rotating shaft to drive the roller and cut into the farmland soil. The cutting force of the ditching blade is used to realize the ditching of farmland water conservancy projects.

[0021] 2. This utility model achieves precise connection between the traction machine and the trenching device by setting up a fastening component. Through the double locking of the drop pin and the positioning pin, a stable traction force is transmitted to ensure that the trenching device will not disengage due to external force during operation, thus avoiding the situation of loosening or falling off the trenching device connection during trenching operations. Furthermore, through the characteristics of automatic coupling and mechanical locking, the traction machine and the trenching device can be quickly connected, reducing the time and physical exertion of manual connection.

[0022] 3. This utility model, by setting up a cutter head maintenance component, can achieve rapid replacement of trenching blades through the cooperation of a compression spring and a plug rod. This allows for quick replacement when trenching blades are worn, cracked, or otherwise damaged, avoiding long-term interruptions to the overall trenching operation due to trenching blade maintenance. At the same time, it can flexibly change to suitable trenching blade specifications according to different farmland soil types, trenching depth, and width requirements, thereby enhancing the versatility of the trenching device in farmland water conservancy projects.

[0032] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0033] According to an embodiment of the present invention, a ditching device for farmland irrigation projects is provided.

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the ditching device for farmland irrigation engineering according to an embodiment of the present utility model includes:

[0035] Connector 1 and drive connector 2 are used for connection with the tractor vehicle;

[0036] The fastening component 3 is located at the connection between the connecting frame 1 and the tractor vehicle, and is used to achieve a tight fastening between the connecting frame 1 and the tractor vehicle.

[0037] The drive control box 4 is located at one end of the drive connector 2 and is used to realize the operation control of trenching work.

[0038] Limiting bracket 5 is installed on both sides of connecting bracket 1;

[0039] The trenching components 6 are located on both sides of the drive control box 4;

[0040] Several cutter head maintenance components 7 are disposed inside the trenching component 6;

[0041] The top of the drive control box 4 is equipped with a soil discharge baffle 8, and the bottom of the soil discharge baffle 8 is equipped with a soil lifting plate 9.

[0042] It should be explained that the drive control box 4 includes a power input device (connected to the tractor's power source, such as a drive shaft or hydraulic interface), a power converter (which converts the input power into speed and torque adapted to the trenching component 6, such as a gearbox or hydraulic motor), a controller (including an operation panel and sensor interface, used to adjust the trenching speed and monitor load and faults), a transmission device (such as a coupling or drive shaft, connected to the rotating shaft of the trenching component 6), and a brake (to stop the trenching action in an emergency). The drive control box 4 is a relatively mature technology for controlling the trenching operation of the trenching component 6, so it will not be elaborated on here.

[0043] In one embodiment, the fastening assembly 3 includes a connecting rod 301 connected to the connecting frame 1 and the tractor. The connecting rod 301 has a first through hole 302 and a second through hole 303 inside. A drop pin 304 is provided inside the first through hole 302, and a positioning pin 305 is provided inside the second through hole 303. A hook 306 is provided inside the positioning pin 305. The connecting rod 301 has a cavity 307 for installing the drop pin 304, thereby enabling precise connection between the tractor and the trenching device. Through the double locking of the drop pin 304 and the positioning pin 305, stable traction force is transmitted to ensure that the trenching device will not disengage due to external force during operation, avoiding loosening or detachment of the trenching device connection during trenching operations. Furthermore, through the automatic coupling and mechanical locking characteristics, the tractor and the trenching device can be quickly connected, reducing the time and physical exertion of manual connection.

[0044] The working principle of the fastening assembly 3 is as follows: the connecting frame 1 and the tractor are connected by the connecting rod 301, and the drop pin 304 and the hook head 306 are respectively connected by the first through hole 302 and the second through hole 303 configured inside the connecting rod 301. The hook head 306 on the connecting frame 1 engages with the hook head 306 of the tractor. The drop pin 304 is locked by the cooperation of the cavity 307 and the first through hole 302, ensuring the mechanical reliability of the connection and preventing the trenching device from becoming loose or falling off during trenching operations.

[0045] In one embodiment, the trenching assembly 6 includes a rotating shaft 601 controlled by a drive control box 4. Rollers 602 are provided on both sides of the rotating shaft 601. Several trenching blades 603 are provided on the outer side of the rollers 602 through a cutter head maintenance assembly 7. Thus, the rotating shaft 601 can drive the rollers 602 to make the trenching blades 603 rotate at high speed and cut into the farmland soil, thereby achieving trenching by utilizing the cutting force of the trenching blades 603.

[0046] In one embodiment, the cutter head maintenance assembly 7 includes a third through hole 701 and a fourth through hole 702 formed inside the roller 602 and the grooving blade 603; a limiting block 703 is provided inside the third through hole 701, an insertion cavity 704 is provided inside the limiting block 703, and a sliding cavity 705 is formed inside the insertion cavity 704; a sliding block 706 is provided inside the sliding cavity 705, a rod 707 is sleeved in the middle of the sliding block 706, and a compression spring 708 is provided at the top of the rod 707, with the top of the compression spring 708 located inside the limiting block 703. The device is equipped with a pressing block 709; inside the pressing block 709 is a stop block 710 that cooperates with the sliding block 706. Thus, the trenching blade 603 can be quickly replaced through the cooperation of the compression spring 708 and the insertion rod 707. This allows for quick replacement when the trenching blade 603 is worn, cracked, or damaged, avoiding long-term interruptions to the overall trenching operation due to maintenance of the trenching blade 603. At the same time, the appropriate trenching blade 603 specification can be flexibly replaced according to different farmland soil types, trenching depth and width requirements, improving the versatility of the trenching device in farmland water conservancy projects.

[0047] The working principle of the cutter head maintenance component 7 is as follows: The roller 602 is used as a carrier, and the grooving blade 603 is positioned on the contact surface of the roller 602. A third through hole 701 (on the side of the roller 602) and a fourth through hole 702 (on the side of the grooving blade 603) are opened on the same axis to provide an insertion channel for the cutter head maintenance component 7. The limiting block 703 is fixed in the third through hole 701 of the roller 602. Its interior includes an insertion cavity 704 (for the insertion rod 707 to move up and down) and a sliding cavity 705 (for the sliding block 706 to move left and right). The sliding block 706 is sleeved in the middle of the insertion rod 707, and the compression spring 708 is sleeved in the top of the insertion rod 707. The two ends abut against the sliding block 706 and the pressing block 709 respectively. The pressing block 709 has two sets of symmetrical stop blocks 710 inside, which cooperate with the protrusion structure of the sliding block 706.

[0048] When a new trenching blade 603 needs to be installed, the compression spring 708 is in a naturally extended state when not in operation, pushing the sliding block 706 to a high position in the sliding cavity 705. At this time, the top of the insertion rod 707 is retracted into the insertion cavity 704 and does not extend into the third through hole 701, which facilitates the fitting and installation of the trenching blade 603. The trenching blade 603 is then fitted against the outside of the roller 602, and the position is adjusted so that the fourth through hole 702 of the trenching blade 603 is completely aligned with the third through hole 701 of the roller 602, ensuring that the insertion rod 707 can smoothly pass through the two holes. The pressing block 709 is then manually pressed down, overcoming the elastic force of the compression spring 708 and pressing downwards. During the movement, the two sets of stop blocks 710 (symmetrically distributed) built into the pressing block 709 move down synchronously, and their inclined surfaces contact the inclined surface of the protrusion of the sliding block 706 and generate pressure. The sliding block 706 and the insertion rod 707 move synchronously. Specifically, the pressure of the stop block 710 causes the sliding block 706 to move slightly to both sides in the horizontal direction within the sliding cavity 705 (to avoid jamming). At the same time, it drives the insertion rod 707 to move vertically downward along the insertion cavity 704. The insertion rod 707 continues to move down, passing through the third through hole 701 of the roller 602 and the fourth through hole 702 of the blade in sequence, until the bottom end of the insertion rod 707 completely penetrates the fourth through hole 702. At this time, the pressing block 709 is released, the compression spring 708 returns to its extension, and the sliding block 706 and the insert rod 707 are pulled upward. The sliding block 706 returns to the high position of the sliding cavity 705, and the top of the insert rod 707 is limited by the sliding block 706, thus achieving rigid fixation between the trenching blade 603 and the roller 602, ensuring that the blade will not loosen during trenching operations.

[0049] When the trenching blade 603 is worn or cracked and needs to be replaced, manually press down on the pressing block 709 to overcome the elasticity of the compression spring 708 and move the pressing block 709 down. At this time, the stop block 710 presses the protrusion of the sliding block 706 again, pushing the sliding block 706 to move horizontally in the sliding cavity 705. At the same time, it drives the insertion rod 707 to move downward along the insertion cavity 704 (in the same direction as during installation, but for the purpose of unlocking) until the top of the insertion rod 707 is driven to the lowest position by the sliding block 706. At this time, the bottom of the insertion rod 707 is completely disengaged from the fourth through hole 702 of the trenching blade 603, releasing the locking constraint on the trenching blade 603. Manually remove the trenching blade 603 from the outside of the roller 602 (because the through hole constraint has been released, the trenching blade 603 can be directly separated along the mating surface). After removing the old blade, release the pressing block 709 to restore the initial state, and the new blade can be installed and connected.

[0050] It should be explained that the limiting block 703 and the pressing block 709 are in a sliding fit relationship with axial constraint and radial limiting. The radial guiding constraint restricts the radial rotation and offset of the pressing block 709, ensuring that it always moves along the axis of the limiting block 703 and avoids lateral separation. The axial limiting constraint ensures that when the pressing block 709 returns to its extreme position, its annular stop edge is completely in contact with the annular shoulder of the limiting block 703, and it cannot continue to move upward because it is blocked by the shoulder. At the same time, the return force of the compression spring 708 always acts downward on the pressing block 709, further strengthening the axial fit. There is no risk of the two falling off or separating.

[0051] Meanwhile, the insertion rod 707 passes through the stepped through hole in the middle of the sliding block 706 from top to bottom. The small diameter section of the through hole and the insertion rod 707 are interference-fitted to form a rigid connection. The vertical support sections at both ends of the sliding block 706 are embedded in the sliding cavity 705 of the limiting block 703 to achieve sliding guidance. The two sets of stop blocks 710 built into the pressing block 709 are wedge-shaped structures. Their lower contact surfaces are inclined surfaces that are adapted to the inclined guide surface of the sliding block 706. When the two end stop blocks 710 fall at the same time, their wedge-shaped inclined surfaces contact the inclined guide surface of the sliding block 706.

[0052] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0053] In practical applications, the connecting frame 1 is first connected to the tractor vehicle via the fastening component 3 to achieve a precise connection between the tractor and the ditching device. The drive connection box is then connected to the control position of the tractor vehicle to complete the connection between the ditching device and the tractor vehicle. During the ditching work in farmland water conservancy projects, the ditching component 6 is controlled by the drive control box 4. The rotating shaft 601 drives the roller 602 to make the ditching blade 603 rotate at high speed and cut into the farmland soil. The cutting force of the ditching blade 603 is used to open the ditch. At the same time, the limit frame 5 limits the two sides of the device to ensure the stability during operation. During the ditching operation, the soil discharge baffle 8 at the top of the drive control box 4 guides the soil generated by the ditching to one side to prevent the soil from falling back into the ditch. The soil lifting plate 9 at the bottom of the baffle assists in lifting the soil, which works with the ditching component 6 to complete the ditching. Overall, the ditching operation in farmland water conservancy projects is carried out stably and efficiently.

[0054] Because the trenching blade 603 is prone to wear during long-term use, especially when working in hard soil, the trenching blade 603 can be replaced through the cutter head maintenance component 7. At the same time, different types of farmland soil, working depth and trenching needs may require different types or shapes of blades. The specifications of the trenching blade 603 can also be adjusted according to actual needs through the cutter head maintenance component 7 during trenching work.

[0055] In summary, with the help of the above-mentioned technical solutions of this utility model, the present utility model has a simple structure and is easy to operate. By setting up the ditching component 6, the rotating shaft 601 drives the roller 602 to make the ditching blade 603 rotate at high speed and cut into the farmland soil. The cutting force of the ditching blade 603 is used to realize the ditching of farmland water conservancy projects. This utility model achieves precise connection between the traction machine and the ditching device by setting up the fastening component 3. Through the double locking of the drop pin 304 and the positioning pin 305, a stable traction force is transmitted to ensure that the ditching device will not be disengaged due to external force during operation, avoiding the situation of loosening or falling off of the ditching device connection during ditching operations. Moreover, through the automatic coupling and mechanical locking characteristics, the traction machine and the ditching device can be quickly connected, reducing the time and physical consumption of manual connection. This utility model, by setting up a cutter head maintenance component 7, enables the rapid replacement of the trenching blade 603 through the cooperation of the compression spring 708 and the insertion rod 707. This allows for quick replacement when the trenching blade 603 is worn, cracked, or otherwise damaged, avoiding prolonged interruptions to the overall trenching operation due to the maintenance of the trenching blade 603. At the same time, it allows for flexible replacement of the appropriate trenching blade 603 specifications according to different farmland soil types, trenching depth, and width requirements, thereby enhancing the versatility of the trenching device in farmland water conservancy projects.
