Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of agricultural machinery, and in particular relates to an anti-tangling tillage machine. Background Technology
[0002] Current tillage machines can perform ditching and sowing. They are divided into towed and self-driven types. Both can use blades inserted into the soil to turn over the soil and make furrows. However, in actual use, straw can easily get tangled in the blades, causing blockages.
[0003] Chinese utility model patent CN 205681823 U provides a tiller with an anti-tangle device at the tiller blade. The device can provide lateral force to the straw by rotating a block connected to the tiller blade, causing the straw to be pushed away from the sides of the tiller blade. However, when a large number of straws become entangled, the anti-tangle device cannot break the straws in time when it comes into contact with the tiller blade, resulting in the straws still getting tangled on the tiller blade and affecting the tiller's operation. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-tangling tillage machine, which solves the problem that the current tillage machines are not strong enough in handling straw that is tangled with each other, and the straw still gets tangled on the tillage blades.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] The utility model content is as follows: An anti-tangle tiller includes a walking frame, on which at least one tiller blade is mounted, and on the tiller blade is an anti-tangle mechanism;
[0007] The anti-winding mechanism includes a top seat fixedly connected to the tiller blade, a set of top plates fixedly connected at intervals on the top seat, and a mounting frame fixedly connected to the frame. A rotary blade that is driven to rotate between the top plates is rotatably connected to the mounting frame. A shearing blade that is rotatably connected to the mounting frame is coaxially placed on both sides of the rotary blade. The rotation direction of the shearing blade is opposite to that of the rotary blade.
[0008] The beneficial effects of this utility model are:
[0009] 1. This utility model includes a frame, on which a tiller blade is mounted. An anti-tangling mechanism is mounted on the tiller blade and includes a set of top plates that extend into the soil and move with the tiller blade, and a rotating paddle blade and a shearing blade that cooperate with the two top plates. The paddle blade rotates in the opposite direction to the shearing blade. Straw blocked by the top plates is lifted by the paddle blade, and the straw is cut off by the interaction between the shearing blade and the paddle blade. This ensures that even tangled straw can be cut off and will not entangle the tiller blade, thus achieving the function of preventing tangling.
[0010] 2. The frame of this utility model is equipped with support wheels and wheels, which are driven by a drive mechanism to adjust the depth of the tillage blades in the soil. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-9 The specific embodiments of this utility model will be further described in detail below.
[0022] In specific implementation, this utility model, in conjunction with the appendix Figure 1-9 An anti-tangle tillage machine includes a walking frame 1, on which at least one tillage blade 2 is mounted. In this embodiment, the tillage machine is not limited to being able to actively drive or need to be dragged. To enable the walking function of the frame 1, a set of connecting plates 11 is mounted on the frame 1. Wheels 12 are rotatably connected to the connecting plates 11 and play a supporting role. Pre-set, to increase the walking stability of the frame 1, a set of support frames 8 is mounted on the frame 1. Each support frame 8 is mounted with a sliding seat 9. Support wheels 10 are rotatably mounted on the sliding seat 9. The support wheels 10 are placed on both sides of the wheel 12 at an angle, that is, the support wheels 10 and the wheel 12 are arranged in a triangle, which improves the stability of the frame 1 during the movement of the frame 1.
[0023] When the machine frame 1 performs actual ditching operations, it is necessary to adjust the depth of the tiller blade 2. In this embodiment, specifically, each support frame 8 is vertically slidably mounted with a sliding seat 9, and a support wheel 10 is rotatably mounted on the sliding seat 9. The sliding seat 9 is driven vertically by a first drive mechanism mounted on the support frame 8. At the same time, a set of connecting plates 11 are hinged to the machine frame 1, and wheels 12 are rotatably connected to the two connecting plates 11. The connecting plates 11 are driven to rotate around their hinge axis by a second drive mechanism mounted on the machine frame 1, so that the depth of the tiller blade 2 in the soil can be adjusted by adjusting the distance between the support wheel 10 and the wheel 12 and the machine frame 1. Preferably, the first drive mechanism includes a first hydraulic telescopic rod 13 mounted on the support frame 8, the extended end of the first hydraulic telescopic rod 13 is fixedly connected to the sliding seat 9, and a guide rod 14 fixedly mounted on the sliding seat 9. The guide rod 14 is vertically slidably engaged with the support frame 8, wherein the guide rod 14 plays a guiding role and restricts the sliding seat. The rotation of 9 enables the sliding seat 9 to slide vertically via the first hydraulic telescopic rod 13, thereby adjusting the distance between the support wheel 10 and the frame 1. The second drive mechanism includes a second hydraulic telescopic rod 15 mounted on the frame 1. A connecting rod 16 is rotatably mounted on the extended end of the second hydraulic telescopic rod 15. The connecting rod 16 slides in a groove 17 on the connecting plate 11, allowing the connecting rod 16 to slide within the groove 17 under the action of the extension and retraction of the second hydraulic telescopic rod 15. This causes the connecting plate 11 to rotate around its hinge axis. The rotatable mounting of the connecting rod 16 and the extended end of the second hydraulic telescopic rod 15 facilitates the sliding of the connecting rod 16 within the groove 17. The second hydraulic telescopic rod 15 drives the connecting plate 11 to rotate around its hinge axis, thereby adjusting the distance between the wheel 12 and the frame 1. This allows for control of the depth of the tiller 2 in the soil by adjusting the wheel 12 and the support wheel 10, while simultaneously balancing the frame 1 as much as possible.
[0024] During the movement of the frame 1, straw may become entangled at the blades 2. To prevent blockage at the blades 2, an anti-entanglement mechanism is installed on the blades 2. The anti-entanglement mechanism includes a top seat 3 fixedly connected to the blade 2, and a set of top plates 4 fixedly connected at intervals on the top seat 3. The top plates 4 are positioned on one side of the moving blades 2, and each blade 2 is equipped with a top plate 4. In this embodiment, when using the blades 2 for trenching, the top plates 4 are positioned above the blades 2, and the bottom of the top plates 4 enters the soil, thereby blocking the straw that should be entangled on the blades 2. At the same time, the top plates 4 are horizontally... The blade is positioned to the left of the tip of the tiller 2 to reduce the resistance of the top plate 4 in breaking the soil. That is, when actually moving, the soil is first turned up by the tiller 2, thereby reducing the resistance encountered by the top plate 4 when it directly penetrates into the soil. The end face of the top plate 4 facing the direction of travel of the frame 1 is set as the blade surface, thereby further reducing the resistance encountered by the top plate 4. The blade surface on the top plate 4 is set at an acute angle to the transverse direction, thereby ensuring that the straw will be blocked by the top plate 4. At the same time, under the effect of the inclined blade surface on the top plate 4, the straw will gradually move away from the ground, avoiding the straw from tangling together.
[0025] It also includes a mounting bracket 5 fixedly connected to the frame 1. A rotating actuating blade 6, positioned between the top plates 4 and driven by a driving device, is rotatably connected to the mounting bracket 5. Preferably, the rotating actuating blade 6 is electrically driven. The motor is mounted on the frame 1 and drives the rotating actuating blade 6 through a transmission component. In this embodiment, the rotating actuating blade 6 is used to hook up straw blocked by the top plate 4, causing the straw to be lifted away from the top plate 4. Preferably, the tip of the rotating actuating blade 6 is provided with a hook. 18. On both sides of the rotating blade 6, a shearing blade 7 is coaxially mounted and rotatably connected to the mounting frame 5. The shearing blade 7 rotates in the opposite direction to the rotating blade 6, ensuring that the straw carried by the rotating blade 6 is cut by the interaction of the shearing blade 7 and the rotating blade 6. The mounting frame 5 is equipped with a cover plate to limit the position of the rotating blade 6, ensuring that the straw carried by the rotating blade 6 will slide out from under the mounting frame 5. The preset configuration is to achieve the rotation of the rotating blade 6 and the shearing blade 7. In this embodiment, a transmission mechanism is preferably provided, with the rotating shaft of the actuating blade 6 and the rotating shaft of the shearing blade 7 being coaxially connected. A connecting plate 19 is fixedly connected to the rotating shaft of the actuating blade 6, and an internal gear 20 is fixedly connected inside the connecting plate 19. An external gear 21 is fixedly connected to the rotating shaft of the shearing blade 7. A transmission gear 22 rotatably connected to the mounting frame 5 meshes between the internal gear 20 and the external gear 21. This satisfies the requirement that when the actuating blade 6 rotates, the rotation directions of the shearing blade 7 and the actuating blade 6 are opposite due to the meshing relationship between the external gear 21 and the transmission gear 22, and between the transmission gear 22 and the external gear 21. In this embodiment, to prevent dust from entering between the rotating plate and the mounting frame 5 and wearing the gear transmission components, a boss 23 is provided on the mounting frame 5 that rotatably engages with the connecting plate 19. A sealing component is provided between the boss 23 and the connecting plate 19. Preferably, a rubber sleeve is provided between the boss 23 and the connecting plate 19 for sealing.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
