Description

Technical Field

[0001] This utility model belongs to the field of agricultural tillage technology and relates to an agricultural machinery tillage device. Background Technology

[0002] Existing agricultural tillage equipment suffers from core defects such as insufficient adaptability to different soil conditions and poor soil covering uniformity. When soil moisture is high, the soil's strong adhesion easily leads to soil accumulation and blockage of the tillage blades, reducing tillage depth and efficiency. The root cause lies in the rough surface treatment of the blades and the limited angle adjustment range, which cannot adapt to the dynamic friction characteristics between clay and the blade surface. Conventional solutions include optimizing the blade coating to reduce adhesion, but the anti-stick coating is prone to wear and requires frequent replacement. The added weight of the press roller increases fuel consumption and exacerbates the compaction phenomenon, damaging the aggregate structure. Layered tillage extends the operation cycle and increases mechanical wear costs. While adding adjustable blades to the guide plate of the soil covering device can improve the soil throwing direction, manual adjustment relies on experience and cannot cope with real-time changes in soil moisture. Therefore, there is an urgent need for an agricultural machinery tillage device to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an agricultural machinery soil turning device to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: an agricultural machinery soil turning device, including: a main connecting frame and thickened blades, the left side of the main connecting frame is provided with several sets of main support frames for connecting, fixing and supporting the main frame, the middle position of the main connecting frame is provided with a set of connecting holes for connecting and fixing with external traction machinery, and the lower ends of the two sets of main support frames on the right side are respectively provided with a set of lower support frames for improving the supporting surface of the main support frame.

[0005] The main frame has a rectangular cross-section when viewed from above, and several sets of lower connecting frames are provided at the lower end of the main frame for connecting and fixing with the soil-turning blades. The lower connecting frames are fixed to the main frame by bolts. Each set of lower connecting frames has a set of soil-turning blades at the lower end for turning the soil in the farmland. The several sets of soil-turning blades are staggered, and their right side view shows a horizontal staggered distribution. The front cross-section of the soil-turning blade has a J-shaped structure, and a set of thickened blades is provided at the lower right side of the soil-turning blade to improve the contact strength between the soil-turning blade and the soil.

[0006] In a preferred embodiment, the thickened blade is made of stainless steel and is fixed to the soil-turning blade by bolts. A set of wing plates for fixing to the rear connecting frame by bolts are respectively provided on the upper sides of the front and rear ends of the left side of the main frame.

[0007] In a preferred embodiment, the wing plate has a set of inner grooves for engaging with the right side of the rear connecting frame. The inner side of the wing plate has several sets of connecting positioning holes for providing support and fixing to the rear connecting frame. In actual use, the wing plate is hinged and fixed to the traction machinery through the connecting holes in the middle of the main connecting frame. During traction operations, the main support frame and the lower support frame are combined to distribute the load stress and prevent structural deformation. The main frame is fixed with several sets of front-view J-shaped and horizontally staggered right-side turning blades by bolts to the lower connecting frame. The thickened blades enhance the soil breaking strength and resist soil erosion at the lower end of the blade. After the turning blades cut into the soil layer as the machinery moves, the J-shaped structure guides the soil to rise and turn laterally. The retaining plate restricts the fall path of the turned soil clods to ensure the formation of trenches. The covering roller then compacts the loose soil and flattens the surface. Before operation, relevant personnel need to check the fitting accuracy between the inner groove of the wing plate and the rear connecting frame. The rear swing frame is fixed by bolts through the connecting positioning holes to maintain the relative positional stability of the covering roller and the retaining plate.

[0008] In a preferred embodiment, the external bolts pass through the connecting positioning holes inside the wing plate and the right side of the rear connecting frame, and are fixed by the limiting nut. A set of covering rollers for leveling the ground after the soil is turned over are provided on the inner side of the left end of the rear connecting frame.

[0009] In a preferred embodiment, the outer side of the covering roller is provided with several sets of soil guiding blades for staggered leveling of the ground, and the left side of the rear connecting frame is provided with a set of rear swing frames for fixing and supporting several sets of retaining plates.

[0010] In a preferred embodiment, several groups of soil-guiding blades are arranged in a ring structure, and for every two groups of ring-shaped soil-guiding blades, several groups of soil-blocking plates are provided on the left side of the rear swing frame to block the soil inside the soil-guiding blades. The soil-blocking plates are arranged in a straight line, and the several groups of soil-blocking plates are fixed to the rear swing frame by bolts. The positioning and assembly are achieved by external bolts passing through the wing plate and connecting the positioning hole to the right side of the rear connecting frame. After the limit nut is tightened, it ensures that the rear connecting frame is rigidly connected to the main shell structure. During operation, the left side of the rear connecting frame... The inner side of the covering roller rolls and flattens the surface of the soil after tilling as the machine moves. The guide blades distributed in a ring on the outer side of the covering roller cut into the soil layer by rotating and pushing the soil displacement in an interlaced trajectory, so as to break up soil clods and evenly cover the soil. The straight-lined retaining plates supported by the rear swing frame on the left side of the rear connecting frame work together with the guide blades to guide the turned soil to flow in a direction along the gaps between the guide blades and block backfilling, so as to avoid secondary burial of the tilled area. The bolt-fixed retaining plates can change the soil guiding path by adjusting the installation angle to adapt to different soil types and working depth requirements.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the main connecting frame is hinged and fixed to the traction machinery through the connecting hole in the middle position of the main connecting frame. During the traction operation, the main support frame and the lower support frame are combined to disperse the load stress and prevent structural deformation. The main frame is fixed with several sets of front-view J-shaped and right-side horizontally intersecting soil-turning blades by bolts of the lower connecting frame. The thickened blades strengthen the soil-breaking strength at the lower end of the blade and resist soil erosion. After the soil-turning blades cut into the soil layer as the machinery moves, the J-shaped structure guides the soil to rise and turn laterally. The retaining plate restricts the fall path of the turned soil clods to ensure the formation of trenches.

[0012] The covering roller then compacts the loose soil to level the surface. Before operation, relevant personnel need to check the fitting accuracy between the inner groove of the wing plate and the rear connecting frame. The rear swing frame is fixed by bolts through the connecting positioning holes to maintain the relative position stability of the covering roller and the retaining plate. The straight-lined retaining plates and guide blades supported by the rear swing frame on the left side of the rear connecting frame work together to guide the turned soil to flow in a directional manner along the gaps between the guide blades and block backfilling, thus avoiding secondary burial of the already tilled area. The bolt-fixed retaining plates can change the soil guiding path by adjusting the installation angle to adapt to different soil types and operating depth requirements. Attached Figure Description
