Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and more specifically, to a subsoiling shovel for a subsoiling machine. Background Technology

[0002] In agricultural production, deep tillage is a crucial step in improving soil structure, aeration, and water retention, playing a key role in promoting crop root growth and increasing crop yield. The deep tillage shovel, as the core working component of the deep tillage machine, directly affects the quality and efficiency of the deep tillage operation.

[0003] Based on the above, the inventors have discovered that traditional subsoil shovels are typically single and fixed structures, unable to effectively loosen soil layers at different depths, requiring frequent replacement of the shovel, resulting in low overall efficiency and poor flexibility. Furthermore, the shovel head and handle of traditional subsoil shovels are often fixed as a single unit, leading to insufficient resistance during use and increased overall shear strength, making it difficult to effectively break up hard plow pans. This affects the continuity of agricultural production and operational efficiency. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a subsoil shovel for subsoilers, aiming to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a subsoiling shovel for a subsoiling machine. It can effectively solve the problems of traditional subsoiling shovels having a single and fixed structure, which cannot be used to loosen soil layers at different depths, resulting in frequent shovel replacements, low efficiency, and poor flexibility. At the same time, it overcomes the defects of traditional subsoiling shovels with a fixed shovel head and handle, which result in high shovel head resistance, high shear strength, difficulty in effectively breaking hard plow pans, and affect the continuity of agricultural production and operational efficiency.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A subsoiler shovel includes a shovel frame, on which multiple fixed shovel handles are fixedly connected. A slide rail is fixedly connected to one side of each fixed shovel handle, and a slide block is slidably connected to the outer periphery of the slide rail. A movable shovel handle is fixedly connected to one side of the slide block. Multiple hydraulic cylinders are fixedly mounted on the top of the shovel frame, and a connecting bracket is fixedly connected to one side of the slide block. One end of the connecting bracket is fixedly connected to the output end of the corresponding hydraulic cylinder. Mounting grooves are provided at the bottom of the fixed and movable shovel handles, and mounting seats are rotatably mounted in the mounting grooves. A first shovel head is fixedly connected to one end of the mounting seat on the fixed shovel handle, and a second shovel head is fixedly connected to one end of the mounting seat on the movable shovel handle.

[0009] Furthermore, the fixed shovel handle and the movable shovel handle have the same structure and are arc-shaped. The mounting groove is located on the upper surface of the bottom end of the fixed shovel handle and the movable shovel handle.

[0010] Furthermore, the slide block is provided with a sliding groove, and the slide block slides along the outer periphery of the slide rail through the sliding groove.

[0011] Furthermore, the hydraulic cylinder is fixed to the top of the shovel frame by an L-shaped bracket, and the output shaft of the hydraulic cylinder faces downwards.

[0012] Furthermore, the mounting groove has an opening at one end, and the mounting base has limiting grooves on both sides at one end near the opening of the mounting groove. A gap is provided between the end of the mounting base near the opening of the mounting groove and the side wall of the mounting groove.

[0013] Furthermore, a threaded column is fixedly connected in the mounting groove, and a limit nut is threadedly connected to the top end of the threaded column. The mounting seat is movably sleeved on the outer periphery of the threaded column and located below the limit nut.

[0014] Furthermore, the first shovel head is a chisel-shaped shovel head, and the second shovel head is an arrow-shaped shovel head.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution achieves targeted loosening operations for soil layers of different depths by setting an adjustable movable shovel handle and a fixed shovel handle cooperation structure. Specifically, the connecting bracket is driven by a hydraulic cylinder, which drives the slide block to slide along the slide rail, thereby causing the movable shovel handle to move up and down relative to the fixed shovel handle, changing the distance between shovel head one and shovel head two and the overall soil penetration depth. When it is necessary to loosen shallow soil, the hydraulic cylinder can be controlled to contract, driving the movable shovel handle to move upward and reducing the soil penetration depth of the shovel head; while when facing deep soil or hard plow pan, the hydraulic cylinder is controlled to extend, pushing the movable shovel handle downward, increasing the soil penetration depth of the shovel head and the tillage force. There is no need to frequently change shovels, which significantly improves the efficiency and operational flexibility, and effectively solves the problem of poor adaptability of traditional deep loosening shovels due to their fixed structure.

[0018] (2) This solution, by adopting an installation structure that connects the mounting base and the shovel handle in a rotating manner, and under the action of the limiting groove, allows shovel head one or two to swing back and forth within a small angle, which can reduce its shear strength and more effectively break the hard plowshare. At the same time, the configuration of different types of shovel heads effectively reduces the working resistance of the shovel head, improves the ability to break the hard plowshare, and ensures the continuity of agricultural production and operational efficiency. The chisel-shaped shovel head (shovel head one) installed at the bottom of the fixed shovel handle has a sharp leading edge, which can concentrate stress and easily cut into the soil. Especially when encountering hard soil clods or plowshares, its impact crushing characteristics can be used to achieve initial loosening. The arrow-shaped shovel head (shovel head two) installed at the bottom of the movable shovel handle has a streamlined design, which reduces the frictional resistance when moving in the soil, and the cutting edges on both sides can further cut and break the initially loosened soil. The two work together to significantly reduce the overall shear strength. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] Please see Figures 1-4 A subsoiler shovel includes a shovel frame 1, with multiple fixed shovel handles 2 fixedly connected to the shovel frame 1. A slide rail 3 is fixedly connected to one side of each fixed shovel handle 2, and a slide seat 4 is slidably connected to the outer periphery of the slide rail 3. A movable shovel handle 5 is fixedly connected to one side of the slide seat 4. Multiple hydraulic cylinders 6 are fixedly installed on the top of the shovel frame 1. A connecting bracket 14 is fixedly connected to one side of the slide seat 4, and one end of the connecting bracket 14 is fixedly connected to the output end of the corresponding hydraulic cylinder 6. Mounting grooves 7 are provided at the bottom of the fixed shovel handles 2 and the movable shovel handles 5. Mounting seats 8 are rotatably installed in the mounting grooves 7. A shovel head 9 is fixedly connected to one end of the mounting seat 8 on the fixed shovel handle 2, and a shovel head 10 is fixedly connected to one end of the mounting seat 8 on the movable shovel handle 5.

[0041] See Figure 3 The fixed shovel handle 2 and the movable shovel handle 5 have the same structure and are arc-shaped. The mounting groove 7 is opened on the upper surface of the bottom end of the fixed shovel handle 2 and the movable shovel handle 5.

[0042] See Figure 3 The slide block 4 has a sliding groove, and the slide block 4 slides on the outer periphery of the slide rail 3 through the sliding groove.

[0043] See Figure 3 The hydraulic cylinder 6 is fixed to the top of the shovel frame 1 by an L-shaped bracket, and the output shaft of the hydraulic cylinder 6 is pointing downwards.

[0044] See Figure 4 The mounting groove 7 has an opening at one end, and the mounting base 8 has limit grooves 11 on both sides at one end near the opening of the mounting groove 7. There is a gap between the end of the mounting base 8 near the opening of the mounting groove 7 and the side wall of the mounting groove 7.

[0045] See Figure 4 A threaded post 12 is fixedly connected in the mounting groove 7. The top of the threaded post 12 is threadedly connected to a limit nut 13. The mounting seat 8 is movably sleeved on the outer periphery of the threaded post 12 and located below the limit nut 13. In use, the mounting seat 8 is rotatably connected to the fixed shovel handle 2 or the movable shovel handle 5. Under the action of the limit groove 11, the shovel head 9 or the shovel head 10 can swing back and forth within a small angle, which can reduce its shear strength, more effectively break the hard plowshare, effectively reduce its working resistance, improve the ability to break the hard plowshare, and ensure the continuity of agricultural production and operational efficiency.

[0046] See Figure 4 The first shovel head 9 is a chisel-shaped shovel head, and the second shovel head 10 is an arrow-shaped shovel head. When in use, the first shovel head 9, which is installed at the bottom of the fixed shovel handle 2, has a sharp leading edge that can concentrate stress and easily cut into the soil. Especially when encountering hard soil clods or plow pans, its impact crushing characteristics can be used to achieve initial loosening. The second shovel head 10, which is installed at the bottom of the movable shovel handle 5, has a streamlined design and experiences less frictional resistance when moving in the soil. Its two cutting edges can further cut and crush the initially loosened soil. The two work together to significantly reduce the overall shear strength.

[0047] In use: First, connect the subsoiler shovel to the power output device of the subsoiler via the shovel frame 1, ensuring a stable overall installation. Before operation, adjust the position of the movable shovel handle 5 by controlling the extension and retraction of the hydraulic cylinder 6, based on the actual conditions of the soil to be worked on, such as soil depth, soil hardness, and the presence of a hard plowshare. When the output end of the hydraulic cylinder 6 extends, it pushes the connecting bracket 14 downward, thereby causing the slide 4 to slide downward along the slide rail 3, causing the movable shovel handle 5 to move downward relative to the fixed shovel handle 2. At this time, the overall soil penetration depth of the shovel head 1 9 and the shovel head 2 10 increases, suitable for scenarios requiring deep tillage or breaking up thick, hard plowshares. When the output end of the hydraulic cylinder 6 retracts, the connecting bracket 14 drives the slide 4 to slide upward along the slide rail 3, the movable shovel handle 5 moves upward, and the overall soil penetration depth decreases, suitable for loosening shallow soil. During the subsoil operation, as the subsoiler moves forward, the shovel head 9 at the bottom of the fixed shovel handle 2 first cuts into the soil. Its sharp leading edge concentrates stress, impacting and breaking up the soil, especially harder clods and plowshares, achieving initial loosening. Following this, the second shovel head 10 at the bottom of the movable shovel handle 5 moves into the soil. Its streamlined design reduces frictional resistance when moving through the soil, and the cutting edges on both sides further cut and break up the already loosened soil, making the soil structure more porous. Simultaneously, because the shovel head is rotatably mounted in the mounting groove 7 via the mounting base 8, and there is a gap between the end of the mounting base 8 near the opening of the mounting groove 7 and the side wall of the mounting groove 7, and with the action of the limiting groove 11, the shovel head can swing back and forth within a small angle when encountering obstacles such as stones in the soil. This buffers the impact, reduces the resistance and shear strength experienced by the shovel head, and prevents damage to the shovel head due to rigid collisions, ensuring the continuity and stability of the operation. Furthermore, when the first shovel head 9 or the second shovel head 10 becomes worn and needs replacement, simply unscrew the limiting nut 13 on the threaded post 12 and remove the mounting base 8 from the opening of the mounting groove 7 to easily replace the shovel head. The operation is simple and quick, effectively reducing maintenance time and further improving work efficiency.
