Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a replaceable blade drag-reducing shovel for deep tillage and fertilization. Background Technology

[0002] The deep tillage and fertilization shovel, installed in front of the seeder, serves the dual function of loosening the soil and applying fertilizer throughout the entire soil layer. As the seeder moves, the shovel penetrates deep into the soil, breaking up compacted layers and improving soil aeration and water permeability, creating a favorable soil environment for crop root growth. Simultaneously, its accompanying fertilization structure can evenly apply various fertilizers, such as nitrogen, phosphorus, and potassium, required for crop growth to a specific depth in a single application, achieving full integration of fertilizer and soil. This ensures that crops continuously receive sufficient nutrients throughout their entire growth cycle, from seedling to maturity, thereby improving fertilizer absorption and utilization rates from the root. This design reduces fertilizer waste and eliminates the need for subsequent topdressing, simplifying the agricultural production process. The structure includes an arc-shaped shovel with a loosening shovel at the end for breaking up and loosening the soil. A soil-dividing blade is located on the arc surface of the shovel to separate the loosened soil to both sides. Symmetrical wing plates are installed on both sides of the shovel. Through the coordinated operation of these components, the depth and scope of deep loosening operations are ensured, while providing a stable channel for fertilizer application. The rear of the shovel typically connects to a fertilizer trough and a material discharge channel. Once the shovel penetrates deep into the soil, fertilizer can smoothly fall through the trough into the designated depth, completing the fertilization process.

[0003] However, the existing deep tillage and fertilization shovel uses a one-piece welded structure, with the soil-splitting blade directly contacting the soil and bearing friction and impact. After long-term operation, it will inevitably wear out and become dull, requiring regular grinding, repair, or replacement. The one-piece structure means that operators must disassemble the entire deep tillage and fertilization shovel from the seeder to handle it, which not only increases the workload of disassembly and installation but also restricts the grinding operation space, making operation difficult and inefficient, and seriously affecting the continuity of agricultural production. Utility Model Content

[0004] The purpose of this invention is to provide a replaceable blade drag-reducing shovel for deep tillage and fertilization, so as to solve the problem that the blades of existing deep tillage and fertilization shovels are not detachable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a replaceable blade drag-reducing shovel for deep tillage and fertilization, comprising:

[0006] The shovel body has a fertilizer trough fixedly installed on one side, a material discharge channel connected to the other side, a loosening shovel movably installed on one side, a soil-dividing blade fixedly connected to the other side, and wing plates symmetrically connected to both sides. A groove is formed near the loosening shovel end of the shovel body, into which an installation block is inserted. The loosening shovel is fixedly connected to the installation block. A first-order insert is fixedly installed inside the groove, with a first-order slot on one side and a first-order bolt on one side. A second-order insert is fixedly installed inside the groove, with a second-order slot on one side and second-order bolts on both sides. Positioning screw holes are formed near the wing plates on the shovel body, with a positioning bolt threaded onto one side of each hole. Several adjusting screw holes are formed near the positioning screw holes on the shovel body, with adjusting bolts threaded onto one side of each hole. The wing plates are installed on one side of the shovel body via positioning bolts and adjusting bolts.

[0007] Furthermore, the mounting block slides against the inner wall of the groove, the first insert block is correspondingly set with the first slot, the first insert block is inserted into the first slot, a first screw hole is opened on one side of the first insert block, and the first bolt passes through the mounting block and is threaded into the first screw hole.

[0008] Furthermore, the second insert block is correspondingly set with the second slot, the second insert block is inserted into the second slot, and the second screw hole is opened on both sides of the second insert block, and the second bolt passes through the mounting block and is threadedly engaged with the second screw hole.

[0009] Furthermore, two reinforcing shafts are fixedly installed inside the groove, and the two reinforcing shafts are symmetrically arranged. The mounting block has two reinforcing holes on the side near the groove, and the reinforcing shafts are inserted into the reinforcing holes.

[0010] Furthermore, the positioning bolt penetrates the wing plate and is threaded into the positioning screw hole, and the adjusting screw hole is distributed in an arc shape.

[0011] Furthermore, the adjusting bolt passes through the wing plate and engages with the adjusting screw hole.

[0012] Compared with existing technologies, this utility model provides a replaceable blade drag-reducing shovel for deep tillage and fertilization. Through the precise insertion and matching of the mounting block and the groove, coupled with the multi-directional bolt locking structure at the end and both sides, it realizes the quick assembly and disassembly of the loosening shovel and the soil-dividing blade. Operators do not need to disassemble the entire shovel body; they only need to loosen the bolts to remove the worn parts. After grinding and repair, it can be quickly reinstalled, reducing maintenance difficulty and workload, saving maintenance time, and ensuring the continuity of agricultural production. When a single part is worn, there is no need to replace the entire shovel body; only the worn part needs to be replaced or repaired, effectively reducing equipment operating costs and extending the overall service life of the equipment.

[0013] The wing plate angle can be flexibly adjusted through the positioning bolts and the arc-shaped adjustment screw holes. It can precisely adjust the opening angle of the wing plate according to the actual needs of different soil textures, moisture, degree of compaction and working depth, thereby optimizing the soil diversion path and minimizing soil resistance during operation. This not only reduces the power consumption of the seeder and improves the working efficiency, but also reduces the risk of deformation and damage to the wing plate due to excessive resistance, and extends the service life of the wing plate.

[0014] The three-way fixing structure, which uses the end locking of bolt No. 1 and the two-sided locking of bolt No. 2, combined with the limiting reinforcement of reinforcing shaft and reinforcing hole, forms a multi-protection connection method. Compared with the traditional single-sided single bolt fixing structure, this structure can restrict the displacement of the installation block from multiple directions, effectively resist the impact and vibration brought by the soil during operation, and ensure that the loosening shovel, the soil separating blade and the shovel body are firmly connected, avoiding loosening, displacement and other situations.

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] Example 1:

[0026] This utility model provides a replaceable blade drag-reducing shovel for deep tillage and fertilization, comprising:

[0027] The shovel body 1 has a fertilizer trough 2 fixedly installed on one side, and a material discharge channel 3 connected to one side of the fertilizer trough 2. A loosening shovel 4 is movably installed on one side of the shovel body 1, and a soil-dividing blade 5 is fixedly connected to one side of the loosening shovel 4. Wing plates 6 are symmetrically connected to both sides of the shovel body 1. A groove 7 is opened at the end of the shovel body 1 near the loosening shovel 4, and an installation block 8 is inserted into the groove 7. The loosening shovel 4 is fixedly connected to the installation block 8. A first insert block 9 is fixedly installed inside the groove 7. A first slot 10 is opened on one side of the installation block 8, and a first insert block 9 is provided on one side. Bolt 12, groove 7 is fixedly installed with a second insert block 13, a second slot 14 is opened on one side of the mounting block 8, and a second bolt 16 is set on both sides of the second insert block 13. The shovel body 1 is provided with a positioning screw hole 19 on the side near the wing plate 6. A positioning bolt 20 is threaded on one side of the positioning screw hole 19. Several adjusting screw holes 21 are opened on the side of the shovel body 1 near the positioning screw hole 19. An adjusting bolt 22 is threaded on one side of the adjusting screw hole 21. The wing plate 6 is installed on one side of the shovel body 1 through the positioning bolt 20 and the adjusting bolt 22.

[0028] Specifically, the mounting block 8 slides against the inner wall of the groove 7, the first insert block 9 is correspondingly set with the first slot 10, the first insert block 9 is inserted into the first slot 10, the first screw hole 11 is opened on one side of the first insert block 9, the first bolt 12 passes through the mounting block 8 and is threaded into the first screw hole 11, the second insert block 13 is correspondingly set with the second slot 14, the second insert block 13 is inserted into the second slot 14, the second screw hole 15 is opened on both sides of the second insert block 13, the second bolt 16 passes through the mounting block 8 and is threaded into the second screw hole 15, two reinforcing shafts 17 are fixedly installed inside the groove 7, the two reinforcing shafts 17 are symmetrically arranged, the mounting block 8 has two reinforcing holes 18 on the side near the groove 7, the reinforcing shafts 17 are inserted into the reinforcing holes 18.

[0029] As can be seen from the above, the fertilizer trough 2 is used for discharging fertilizer. The fertilizer reaches the fertilizer trough 2 through the discharge channel 3, and then the fertilizer trough 2 disposes of the fertilizer into the soil. Specifically, several fertilizer holes at different heights are opened on the rear wall of the fertilizer trough 2 to distribute the fertilizer to different heights below the soil. A fertilizer pipe is installed below the first layer of fertilizer holes to ensure the height of the first layer of fertilizer. Each subsequent layer of fertilizer holes is equipped with a fertilizer discharging plate or fertilizer discharging pipe on its lower side. A fertilizer adjustment plate is provided on the uppermost side of the rear wall of the fertilizer trough 2. The position of the fertilizer adjustment plate is adjusted according to the fertilizer amount required at different depths, thereby controlling the fertilizer distribution at different depths. This part is existing public technology and will not be described in detail here. The groove 7 is opened at the end of the shovel body 1 near the loosening shovel 4 and is used to install the block 8. The mounting carrier has an internal structure that precisely matches the mounting block 8, providing a stable installation space and positioning reference for the mounting block 8. One end of the mounting block 8 is fixedly connected to the loosening shovel 4, and the other end is inserted into the groove 7. Its core function is to achieve a detachable connection between the loosening shovel 4 and the shovel body 1, thereby enabling the disassembly of the soil-separating blade 5. The first insert 9 is fixed inside the groove 7, and the first slot 10 is opened at the corresponding position of the mounting block 8. The two form a precise positioning and mating structure, the core function of which is to axially position the mounting block 8, ensuring that the mounting block 8 can be accurately aligned with the installation position after being inserted into the groove 7, avoiding lateral displacement. The first screw hole 11 is opened on one side of the first insert 9, and the first bolt 12 passes through the mounting block 8. The first screw hole 11 is threaded into the first screw hole 11, forming an end locking structure. Its function is to fasten from the end of the mounting block 8, firmly fixing the mounting block 8 and the first insert block 9, restricting the axial displacement of the mounting block 8. The fastening force of the threaded connection resists the impact force of the soil on the loosening shovel 4 during operation, ensuring that the connection does not loosen. The second insert block 13 is fixed inside the groove 7, and the second slot 14 is opened at the corresponding position of the mounting block 8. Its function is to position the mounting block 8 from the side, complementing the axial positioning of the first insert block 9, further improving the positioning accuracy of the mounting block 8. The second screw hole 15 is opened on both sides of the second insert block 13, and the second bolt 16 passes through the mounting block 8 and is threaded into the second screw hole 15, forming a side... The locking structure is designed to fasten the mounting block 8 from both sides, forming a three-way locking pattern with the end of the first bolt 12. This comprehensively restricts the displacement of the mounting block 8. The reinforcing shaft 17 is fixed inside the groove 7 and is symmetrically arranged. The reinforcing hole 18 is opened at the corresponding position of the mounting block 8. The two together constitute an auxiliary reinforcement structure. Its core function is to further restrict the displacement of the mounting block 8 and improve the vibration and impact resistance of the connection. After the reinforcing shaft 17 is inserted into the reinforcing hole 18, it forms a rigid support, which can effectively resist the lateral impact force on the loosening shovel 4 during operation and prevent the mounting block 8 from shaking or displacing slightly in the groove 7. Together with the bolt locking structure, it forms multiple protections and improves the overall connection stability.

[0030] Specifically, the positioning bolt 20 passes through the wing plate 6 and is threaded into the positioning screw hole 19, the adjusting screw hole 21 is distributed in an arc, and the adjusting bolt 22 passes through the wing plate 6 and is threaded into the adjusting screw hole 21.

[0031] As can be seen from the above, the positioning screw holes 19 are opened on both sides of the shovel body 1, and the positioning bolts 20 penetrate the wing plate 6 and are threaded into the positioning screw holes 19, forming the axial positioning structure of the wing plate 6. Its core function is to provide a fixed rotation axis for the wing plate 6, ensuring that the wing plate 6 can rotate precisely around the axis when the angle is adjusted, and avoiding deviation during the adjustment process. After the positioning bolts 20 are tightened, the axial position of the wing plate 6 can be firmly fixed, providing a basis for locking the adjusting bolts 22 and ensuring the stability of the wing plate 6 after angle adjustment. The adjusting screw hole 21 is opened on the shovel body 1 near the positioning screw hole 19. On one side of the screw hole 19, the adjusting bolt 22 is arranged in an arc. It passes through the wing plate 6 and is threaded into the adjusting screw hole 21 to form the angle locking structure of the wing plate 6. Its core function is to fix the angle of the wing plate 6 after adjustment. Through the arc-shaped distribution of the adjusting screw hole 21, multiple angle locking positions are provided for the wing plate 6, so as to realize the flexible adjustment of the angle of the wing plate 6. After the adjusting bolt 22 is tightened, the wing plate 6 is firmly fixed to the shovel body 1 to resist the soil resistance during operation and ensure that the angle of the wing plate 6 does not change. At the same time, the threaded connection method facilitates subsequent readjustment according to the operation requirements.

[0032] Working principle: First, align the mounting block 8 with the groove 7 at the end of the shovel body 1 and slowly insert it, so that the first insert block 9 is accurately inserted into the first slot 10, the second insert block 13 is accurately inserted into the second slot 14, and the reinforcing shaft 17 is accurately inserted into the reinforcing hole 18, achieving multi-directional positioning. After positioning, take out the first bolt 12, pass it through the mounting block 8 and align it with the first screw hole 11, and slowly screw it in and tighten it with a tool to lock the mounting block 8 from the end and limit its axial displacement. Then, take out the second bolts 16 on both sides, pass them through the mounting block 8 respectively and align them with the second screw holes 15 on both sides of the second insert block 13, and screw them in symmetrically. Tighten evenly to lock the mounting block 8 from both sides, forming a three-way locking pattern at the end and both sides. When it is necessary to adjust the angle of the wing plate 6, first loosen the positioning bolt 20 on the wing plate 6 with a tool, then loosen and remove the adjusting bolt 22. With the positioning bolt 20 as the axis, slowly rotate the wing plate 6 to adjust to the preset angle. After the angle is adjusted, observe the alignment of the bolt hole on the wing plate 6 with the adjusting screw hole 21 on the shovel body 1. Select the adjusting screw hole 21 with the corresponding angle, insert the adjusting bolt 22 through the wing plate 6 and align it with the adjusting screw hole 21, slowly screw it in and tighten it to complete the locking of the angle of the wing plate 6.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
