Description

Technical Field

[0001] This utility model relates to the field of agricultural tillage machinery technology, and in particular to a depth adjustment mechanism for agricultural tillage machinery. Background Technology

[0002] Soil tillage machinery refers to agricultural machinery used to process and manage the topsoil. It is mainly used for tasks such as breaking up the plow pan, restoring soil structure, improving water retention capacity, and leveling the surface. Based on tillage methods, it can be divided into basic tillage machinery and topsoil tillage machinery. Through methods such as cutting, crushing, and turning, it adapts to different environmental needs. When using agricultural tillage machines, the tillage depth needs to be adjusted.

[0003] As shown in the reference case "An agricultural machinery device for easy adjustment of working depth" (publication number CN222803364U), by setting an extension plate fixedly connected to a semi-circular arc gear, when the arc gear rotates, it drives the plowing blade on the extension plate and the extension plate to rotate together. Since the centers of the arc gear and the connecting plate do not overlap, the rotation trajectory of the extension plate and the connecting plate are not concentric circles. As a result, the plowing blades at different positions on the extension plate are at different heights when they are at the same angle, which not only realizes the adjustment of working height, but also ensures that the plowing blade can be inserted into the soil at a certain angle.

[0004] According to the aforementioned references, the rotation of the arc-shaped gear in the device drives the extension plate, causing the plow blade on the extension plate to rotate. Because the rotation trajectory of the extension plate is not concentric with the connecting plate, the height of the plow blade varies at different positions, achieving effective soil turning and cultivation. However, when using an agricultural tiller, the extension plate and plow blade are not ideal for adjusting the tillage depth, affecting the tillage depth of the tiller and making it inconvenient to adjust, thus reducing the overall effectiveness of the agricultural tiller. Utility Model Content

[0005] Therefore, it is necessary to provide a depth adjustment mechanism for agricultural tillage machines to address the problem of inconvenience in adjusting the tillage depth of agricultural tillage machines.

[0006] The device includes a mounting frame with two plow blades installed on its inner wall; an adjustment mechanism for adjusting the tillage depth of the agricultural tiller, also installed on the inner wall of the mounting frame; the adjustment mechanism includes a mounting plate slidably connected to the inner wall of the mounting frame, with both plow blades mounted on the inner wall of the mounting plate; connecting rods are fixedly connected to both sides of the top of the mounting plate; lead screws are rotatably connected to both sides of the inner wall of the mounting frame, and the lead screws are threadedly connected to the connecting rods; and a protective assembly is provided on the inner wall of the mounting frame.

[0007] In one embodiment, the adjustment mechanism includes a worm gear fixedly connected to the top of the lead screw, the worm gear being rotatably connected to the inner wall of the mounting bracket, and a worm being meshed with one side of the worm gear.

[0008] In one embodiment, a rotating rod is fixedly connected between the two worm gears.

[0009] In one embodiment, one end of the rotating rod passes through one of the worm gears in sequence and extends to the outer wall of the mounting frame, and one end of the mounting frame is fixedly connected to a handle.

[0010] In one embodiment, the protective component includes protective cylinders fixedly connected to both sides of the inner wall of the mounting bracket, the protective cylinders being slidably connected to the outer wall of the connecting rod.

[0011] In one embodiment, guide rods are fixedly connected to the four corners of the top of the mounting plate, and the top ends of the guide rods are slidably connected to the inner wall of the mounting frame.

[0012] In one embodiment, two mounting rods are fixedly connected to both sides of the top of the mounting frame, and counterweights are installed at the top of the two mounting rods.

[0013] In one embodiment, the top end of the mounting rod is threaded with a retaining sleeve. Beneficial effects

[0014] 1. The depth adjustment mechanism for the above-mentioned agricultural tillage machine has two plow blades at the bottom of the mounting plate that can be driven to move up and down through connecting rods and lead screws to adjust the tillage depth. By rotating the rod, two worm gears can be driven to cooperate with two worm wheels, and the two worm wheels can drive the two lead screws to rotate. The lead screws can simultaneously drive the two connecting rods to move and adjust, which can provide stable support for the mounting frame and prevent the plow blades from shifting during tillage. This allows for adjustment of the tillage depth of the agricultural tillage machine and improves the tillage effect of the agricultural tillage machine.

[0015] 2. The protective sleeve on the outer wall of the connecting rod can protect the lead screw and prevent soil from adhering to it, thus affecting its use. Multiple guide rods are fixed at the four corners of the top of the mounting plate, which can limit and guide the mounting plate and the plow blade, and provide stable support for the plow blade. The mounting frame, through the cooperation of the mounting rod and the counterweight, can apply pressure to the mounting frame and the plow blade to prevent the plow blade from tilting upwards during cultivation. The fixing sleeve can fix the counterweight, which can improve the cultivation effect of the plow blade and improve the use effect of the agricultural tillage machine. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-5 This invention describes a depth adjustment mechanism for an agricultural tillage machine.

[0026] In one embodiment, a depth adjustment mechanism for an agricultural tillage machine includes a mounting frame 100, with two plow blades 200 disposed on the inner wall of the mounting frame 100; and an adjustment mechanism 300 disposed on the inner wall of the mounting frame 100 to adjust the tillage depth of the agricultural tillage machine. The adjustment mechanism 300 includes a mounting plate 310 slidably connected to the inner wall of the mounting frame 100, with both plow blades 200 mounted on the inner wall of the mounting plate 310. Connecting rods 320 are fixedly connected to both sides of the top of the mounting plate 310, and lead screws 330 are rotatably connected to both sides of the inner wall of the mounting frame 100. The lead screws 330 are threadedly connected to the connecting rods 320. A protective component 380 is disposed on the inner wall of the mounting frame 100.

[0027] It should be noted that agricultural tillage machinery is...

[0028] Power machinery: This is the core component of agricultural tillage machinery, usually referring to a tractor or engine, providing the power source required for the unit's operation. The power machinery is the power source of the entire unit, responsible for driving other working parts.

[0029] Agricultural machinery: These are the functional components, such as seeders and harvesters, responsible for completing specific agricultural production tasks. Agricultural machinery directly participates in operations such as tilling, sowing, and harvesting, and is a key part of achieving agricultural production goals.

[0030] Transmission system: Responsible for transmitting power from the power machinery to the working machinery, including components such as gearboxes and drive shafts. The transmission system ensures that power can be transmitted to the working machinery efficiently and stably, guaranteeing the normal operation of the unit.

[0031] Operating and control devices: These include the driving operating system and hydraulic control unit, used to control the unit's operating status. The operating and control devices enable operators to easily control various functions of the unit, improving operational efficiency and safety.

[0032] Towing or suspension device: This is the mechanical connection component between the power machinery and the working machinery, determining the combination method: towing or suspension. The towing or suspension device ensures a stable connection between the power machinery and the working machinery, guaranteeing the stability and efficiency of the unit during operation.

[0033] When tilling the land with an agricultural tiller, the moldboard plow can be installed via a traction device. The tractor drives the moldboard plow to cut the soil clods and guide them up to the plowshare, completing the tilling task. The adjustment mechanism 300, through the worm gear 340 and worm 350, drives the lead screw 330 and connecting rod 320 to adjust the tilling depth of the plow blade 200. The protective component 380, through the counterweight 384, prevents the mounting frame 100 from tilting up during tilling. The adjustment mechanism 300 and the protective component 380 work together to optimize the tilling effect of the agricultural tiller without affecting its normal operation.

[0034] like Figure 2 and Figure 3 As shown, the adjustment mechanism 300 includes a worm gear 340 fixedly connected to the top of the lead screw 330. The worm gear 340 is rotatably connected to the inner wall of the mounting bracket 100. A worm 350 is meshed with one side of the worm gear 340. A rotating rod 360 is fixedly connected between the two worms 350. One end of the rotating rod 360 passes through one of the worms 350 and extends to the outer wall of the mounting bracket 100. A handle 370 is fixedly connected to one end of the mounting bracket 100.

[0035] In this embodiment, the handle 370 can drive the worm gear 350 on the rotating rod 360 to be threadedly connected to the worm wheel 340. The worm wheel 340 can drive the two lead screws 330 to rotate synchronously. The lead screw 330 is threadedly connected to the connecting rod 320, which can drive the plow blade 200 at the bottom of the mounting plate 310 to move downward, thereby adjusting the tillage depth of the plow blade 200. This can effectively adjust the tillage depth of the agricultural tillage machine and improve the use effect of the agricultural tillage machine.

[0036] like Figure 4 and Figure 5 As shown, the protective assembly 380 includes protective cylinders 381 fixedly connected to both sides of the inner wall of the mounting bracket 100. The protective cylinders 381 are slidably connected to the outer wall of the connecting rod 320. Guide rods 382 are fixedly connected to the four corners of the top of the mounting plate 310. The top ends of the guide rods 382 are slidably connected to the inner wall of the mounting bracket 100. Two mounting rods 383 are fixedly connected to both sides of the top of the mounting bracket 100. Counterweights 384 are installed at the top ends of the two mounting rods 383. Fixed sleeves 385 are threadedly connected to the top ends of the mounting rods 383.

[0037] In this embodiment, when the mounting plate 310 drives the plow blade 200 to move downward, multiple guide rods 382 pass through the mounting frame 100 and move downward with the mounting plate 310, providing guidance and support for the mounting plate 310. The protective cylinder 381 can protect the lead screw 330 and reduce the impact of soil on the lead screw 330. The counterweight 384, in conjunction with the two mounting rods 383, can apply pressure to the mounting frame 100, improving the stability of the plow blade 200 during movement and enhancing the tillage effect of the device.

[0038] Working principle: The mounting bracket 100 can be installed with the tractor via the connecting bracket at the front end. Manually turning the handle 370 drives the worm gears 350 at both ends of the rotating rod 360 to be threadedly connected to the two worm wheels 340, which in turn drives the two lead screws 330 to rotate. The two lead screws 330 are threadedly connected to the two connecting rods 320 respectively. The connecting rods 320 drive the two plow blades 200 at the bottom of the mounting plate 310 to be inserted into the ground. As the lead screws 330 rotate, the depth of the plow blades 200 can be adjusted. The mounting plate 310 moves downward, and the guide rod 382 moves downward as well. The counterweight 384 is installed above the mounting bracket 100 via the two mounting rods 383. The fixing sleeve 385 is threadedly connected to the mounting rods 383 to limit the counterweight 384.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
