Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a rotary tiller head spraying device. Background Technology

[0002] Rotary tillers are typically used in environments containing pesticides, fertilizers, and are damp and corrosive. During operation, the tillers also rub against gravel and crop residue in the soil, accompanied by vibration and impact, leading to increased wear and a shortened lifespan. Some researchers have proposed using surface strengthening technologies to manufacture rotary tillers, with the most representative methods being surface laser shock peening and surface chromium infiltration. Other researchers have proposed using arc spraying to dimensionally repair rotary tillers, enabling remanufacturing and recycling.

[0003] In existing technologies, equipment for arc spraying typically involves fixing rotary tillers by inserting them into fixed holes, and then spraying the tiller blades with a fixed spray gun. However, in practical use, the rotary tillers are not always securely fixed, and the fixed spray gun cannot freely adjust its angle according to the wear condition of the tiller blades, resulting in low spraying efficiency.

[0036] Reference Figure 1 This utility model proposes a rotary tiller head spraying device, including a clamp 100 for holding a rotary tiller 600; a base 200 located on one side of the clamp 100; a sliding member 300 slidably disposed on the base 200, and the sliding member 300 moves closer to or away from the clamp 100 after sliding; a connecting member 400 rotatably disposed on the sliding member 300 at one end, and the connecting member 400 moves closer to or away from the clamp 100 after rotating; and a spray gun 500 disposed at the other end of the connecting member 400, and the spray gun 500 is used to spray the rotary tiller 600.

[0037] In this embodiment, a rotary tiller blade 600 head spraying device mainly comprises a clamp 100 for holding the rotary tiller blade 600. A base 200 is disposed on one side of the clamp 100, and a sliding member 300 is slidable on the base 200, moving closer to or away from the clamp 100 during sliding. One end of a connecting member 400 is rotatably disposed on the sliding member 300, moving closer to or away from the clamp 100 during rotation. A spray gun 500 is mounted on the other end of the connecting member 400 for spraying the blade head of the rotary tiller blade 600.

[0038] In actual operation, the rotary tiller 600 is first stably clamped by the clamp 100. According to the wear condition of the rotary tiller 600 blade head, the sliding member 300 is used to adjust the front and rear position of the spray gun 500, and then the connecting member 400 is rotated to adjust the angle of the spray gun 500 so that the spray gun 500 can spray the rotary tiller 600 head at the optimal angle and position.

[0039] The cooperation between the sliding component 300 and the connecting component 400 makes the position and angle adjustment of the spray gun 500 more convenient and flexible, adapting to rotary tillers 600s of different shapes and wear levels, thus improving the versatility of the device. It effectively solves the problem of the inflexible angle adjustment of the spray gun 500, enabling precise positioning for spraying based on the actual wear condition of the rotary tiller 600 head, thereby improving spraying efficiency and quality.

[0040] Furthermore, the connector 400 includes a first connecting rod 410, one end of which is rotatably mounted on the sliding member 300; and a second connecting rod 420, one end of which is rotatably mounted on the sliding member 300. The first connecting rod 410 and the second connecting rod 420 are parallel to each other, and the other ends of the first connecting rod 410 and the second connecting rod 420 are both hinged to the spray gun 500.

[0041] In this embodiment, the connector 400 includes a first link 410 and a second link 420. One end of the first link 410 is rotatably mounted on the slider 300, and one end of the second link 420 is also rotatably mounted on the slider 300. The first link 410 and the second link 420 are parallel to each other. The other ends of the first link 410 and the second link 420 are both connected to the spray gun 500 by hinges. Thus, the first link 410, the second link 420, the slider 300, and the spray gun 500 together form a four-bar linkage structure.

[0042] In actual operation, by utilizing the characteristics of the four-bar linkage structure, a certain point on the first link 410 or the second link 420 is fixedly hinged, and the sliding member 300 slides to drive the first link 410 and the second link 420 to move, thereby realizing the flexible adjustment of the spray gun 500 at multiple angles in space. This allows the spray gun 500 to accurately aim at various positions of the rotary tiller 600 head, achieving accurate spraying regardless of whether the area is severely worn or the part has a complex shape.

[0043] The application of the four-link structure greatly increases the flexibility and precision of the spray gun 500 angle adjustment, enabling highly accurate spraying operations for various complex wear conditions of the rotary tiller blades 600. This structure effectively improves the stability and reliability of the spray gun 500 during adjustment, avoiding uneven or inaccurate spraying caused by spray gun 500 shaking, and significantly improving the quality and effect of spraying.

[0044] Furthermore, it also includes a first telescopic member 700, one end of which is hinged to the base 200 and the other end is hinged to the first connecting rod 410 or the second connecting rod 420. The first telescopic member 700 is used to drive the first connecting rod 410 and the second connecting rod 420 to rotate.

[0045] In this embodiment, one end of the first telescopic member 700 is hinged to the s200, and the other end is hinged to the first connecting rod 410 or the second connecting rod 420. The hinge between the first telescopic member 700 and the base 200 can be controlled by a servo motor to adjust the rotation angle, or it can be manually adjusted and fixed by means of clamps, bolts, etc. The first telescopic member 700 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, etc.

[0046] In actual operation, the first telescopic component 700 drives the first connecting rod 410 and the second connecting rod 420 to rotate around their connection point with the sliding component 300 through its telescopic movement. This rotation can cause the spray gun 500 connected to it to change its angle and position, thereby more accurately aligning it with the area to be sprayed by the rotary tiller blade 600.

[0047] This versatile articulated design increases the flexibility and adaptability of the device's operation, meeting the demands of automated, high-efficiency production while also accommodating special situations requiring precise manual adjustments. Servo motor control of the rotation angle improves adjustment accuracy and efficiency, reduces human error, and ensures consistent and high-quality coating. The manual adjustment and fixing method allows operators to flexibly adapt to actual site conditions, lowering the barrier to entry and reducing costs associated with using the equipment.

[0048] Furthermore, it also includes a second telescopic member 800, which is disposed on the base 200. The telescopic end of the second telescopic member 800 is disposed on the slider 300, and the second telescopic member 800 is used to drive the slider 300 to slide.

[0049] In this embodiment, the second telescopic member 800 is mounted on the base 200, and its telescopic end is connected to the sliding member 300. In actual operation, the second telescopic member 800 drives the sliding member 300 to slide on the base 200 through its telescopic movement. The sliding of the sliding member 300 can drive the connected connecting member 400 and the spray gun 500, thereby adjusting the horizontal position of the spray gun 500. The second telescopic member 800 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, etc.

[0050] The second telescopic component 800 automates the sliding of the sliding component 300, improving the efficiency and accuracy of the horizontal position adjustment of the spray gun 500. This allows the spray gun 500 to quickly and accurately reach the desired spraying position, further enhancing the efficiency and quality of the spraying operation. It also reduces the workload of operators and minimizes errors and uncertainties caused by human operation.

[0051] Furthermore, the clamp 100 includes a base 110, which is located on one side of the base 200 and below the slider 300; a swing frame 120 is swingably mounted on the base 110, and after the swing frame 120 swings, one end approaches or moves away from the upper surface of the base 110; a chuck 130 is mounted at one end of the swing frame 120, and after the swing frame 120 swings, the chuck 130 is used to clamp the rotary tiller 600 with the upper surface of the base 110.

[0052] In this embodiment, the clamp 100 consists of a base 110, a swing frame 120, and a chuck 130. The base 110 is located on one side of the base 200 and below the slider 300. The swing frame 120 is swingably mounted on the base 110, and one end of it can move closer to or further away from the upper surface of the base 110 when swinging. The chuck 130 is mounted on one end of the swing frame 120, and when the swing frame 120 swings, the chuck 130 can engage with the upper surface of the base 110 to clamp the rotary tiller 600. The chuck 130 can be made of a high-friction soft material to avoid damage to the surface of the rotary tiller.

[0053] In actual operation, the rotary tiller 600 is placed on the upper surface of the base 110, and then the swing frame 120 is swung to bring the chuck 130 close to the upper surface of the base 110, thereby firmly clamping the rotary tiller 600. This clamp 100 has a simple structure, is easy to operate, and can quickly and effectively clamp the rotary tiller 600, improving work efficiency. The cooperation between the swing frame 120 and the chuck 130 provides a reliable clamping force, ensuring that the rotary tiller 600 will not shift during the spraying process, thus guaranteeing the accuracy and quality of the spraying. The design of the base 110 located below the sliding member 300 makes reasonable use of space, making the entire device structure more compact.

[0054] Furthermore, it also includes a third telescopic member 140, which is disposed on the base 110. The telescopic end of the third telescopic member 140 is hinged to one end of the swing frame 120 away from the chuck 130, and the swing center of the swing frame 120 is located between the third telescopic member 140 and the chuck 130.

[0055] In this embodiment, a third telescopic member 140 is used. The fixed end of the third telescopic member 140 is mounted on the base 110 via a hinge seat, and its telescopic end is hinged to the end of the swing frame 120 away from the clamp 130. The swing center of the swing frame 120 is located between the third telescopic member 140 and the clamp 130. The third telescopic member 140 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, etc.

[0056] In actual operation, the third telescopic component 140, through its telescopic movement, drives the swing frame 120 to swing around its swing center. When the telescopic component extends, it pushes the end of the swing frame 120 away from the chuck 130 upward, bringing the chuck 130 closer to the upper surface of the base 110, thus clamping the rotary tiller 600. When the telescopic component shortens, it pulls the end of the swing frame 120 away from the chuck 130 downward, moving the chuck 130 away from the upper surface of the base 110, thus releasing the rotary tiller 600.

[0057] The third telescopic component 140 enables automatic control of the swing of the swing frame 120, improving the efficiency and convenience of clamping and releasing the rotary tiller blades 600. It can provide a stable and controllable clamping force, ensuring that the rotary tiller blades 600 can be firmly clamped under different working conditions, thus improving the reliability of the device.

[0058] Furthermore, the base 110 has a support rod 111, which is located on the side of the base 110, and the swing frame 120 is swing-mounted on the support rod 111.

[0059] In this embodiment, the support rod 111 provides support for the swing frame 120 and creates a certain gap between the swing frame 120 and the base 110 to avoid interference between the swing frame 120 and the base 110 during the swinging process.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
