Description

Technical Field

[0001] This utility model belongs to the field of saline-alkali land management technology, specifically relating to an integrated machine for opening trenches and sowing seeds in saline-alkali land. Background Technology

[0002] Rapid drainage and salt removal, along with groundwater level control, are crucial for the transformation and utilization of saline-alkali land. Rat tunnel drainage can replace underground pipes, significantly reducing costs. This technology involves constructing "rat tunnels" in the deep soil. When heavy water or concentrated rainfall occurs, the soil is leached, and the salt-laden water infiltrates into the tunnels. This allows the water and salt in the saline-alkali land to quickly flow into drainage ditches and be discharged, preventing salt accumulation in the deep soil and thus reducing soil salinity.

[0003] During the construction of rodent tunnels, the ditching equipment creates loose, low-salt gullies on the soil surface that connect to the tunnels. These gullies, once filled, can serve as seeding strips, promoting crop germination and growth. However, currently, there are no integrated machines for both rodent tunnel installation and seeding. Furthermore, when seeders are used to sow seeds in saline-alkali land with existing rodent tunnels, the presence of these gullies makes it easy for the seeds released by the seeder to fall into the tunnels, resulting in seed waste. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an integrated machine for opening and planting rat tunnels in saline-alkali land. Through the cooperation between the ditching mechanism, the rotary tillage mechanism, and the seeder, it realizes the integrated operation of opening rat tunnels, backfilling gullies, and planting, avoiding seeds falling into the rat tunnels and improving work efficiency.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A salt-alkali gopher tunnel trenching and seeding integrated machine includes a frame and a trenching mechanism mounted on the frame. A rotary tillage mechanism and a seeder are sequentially added behind the trenching mechanism on the frame. The trenching mechanism is connected to the frame by means of a plow blade and penetrates deep into the soil. The rotary tillage end of the rotary tillage mechanism and the seeding end of the seeder are located on the soil surface. The travel trajectories of the rotary tillage mechanism and the seeder coincide with the travel trajectory of the trenching mechanism. The trenching mechanism forms trenches between the soil surface and the gopher tunnels. The soil around the trenches is broken up and backfilled by the rotary tillage mechanism.

[0007] The trenching mechanism includes a trenching shovel and a sizing device disposed at the tail of the trenching shovel. The trenching shovel forms the trenching end of the trenching mechanism. The trenching shovel is fixedly connected to the front end of the frame by means of a plow blade. The cutting ends of the plow blade and the trenching shovel both face the forward direction of the frame. The sizing device has a bullet-shaped structure, with the small-diameter end of the sizing device facing the forward direction of the frame.

[0008] A reinforcing rib is also connected between the waist of the plow blade and the bottom of the frame, and the plow blade, frame and reinforcing rib together form a triangular support structure.

[0009] A backfill shovel is also provided on the back side of the plow blade. The backfill shovel is located between the bottom plane of the rotary tillage end of the rotary tillage mechanism and the top plane of the furrowing shovel. The backfill shovel has an isosceles triangular sheet structure. The backfill shovel is set in the horizontal direction and the apex of the backfill shovel faces the backward direction of the frame. The waist side of the backfill shovel is folded to form a gathering wing. The gathering wing is symmetrically arranged on both sides of the center line of the backfill shovel. The soil on both sides of the furrow is gathered into the furrow by the gathering wing to form backfill.

[0010] The rotary tillage mechanism includes a rotary tillage shaft and rotary tillage components mounted on the rotary tillage roller. Each rotary tillage component includes rotary tillage blades arranged symmetrically in a figure-eight shape. At least three sets of rotary tillage components are arranged along the axial direction of the rotary tillage shaft. The middle rotary tillage component forms the rotary tillage end of the rotary tillage mechanism. The adjacent rotary tillage components are symmetrically arranged on both sides of the middle rotary tillage component. The included angle between adjacent rotary tillage components along the axial direction of the rotary tillage shaft is 90°. The vertical plane of the inner rotary tillage blade of the adjacent rotary tillage component passes through the outer rotary tillage blade of the middle rotary tillage component.

[0011] The rotary tillage mechanism also includes a rotary tillage roller, which is located behind the rotary tillage end of the rotary tillage mechanism. The rotary tillage roller and the rotary tillage end of the rotary tillage mechanism are arranged collinearly along the forward direction of the frame.

[0012] A sowing and pressing wheel is also provided on the frame behind the seeder. The sowing and pressing wheel is located behind the sowing end of the seeder and is arranged collinearly with the sowing end of the seeder along the forward direction of the frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. The integrated machine in this utility model achieves integrated operation of ditching, backfilling and sowing of rat tunnels through the cooperation of the ditching mechanism, rotary tillage mechanism and seeder. It avoids seeds falling into the rat tunnels, improves the planting efficiency of saline-alkali land, and only requires one operation, which reduces the damage to the soil morphology, avoids excessive soil compaction and is less likely to cause the rat tunnels to collapse.

[0015] During operation, after the trenching shovel creates a trench between the soil surface and the rat trail, the rotary tillage mechanism behind it immediately breaks up and refines the soil on both sides of the trench and backfills the broken soil into the trench, thus sealing the trench directly above the rat trail and providing planting space for subsequent sowing.

[0016] 2. This utility model adds a backfill shovel to the plow blade of the ditching mechanism. The waist side of the backfill shovel is folded to form a converging wing. The folding structure of the converging wing makes the backfill shovel form a guide channel that is wider at the front and narrower at the back. The front end of the converging wing cuts and breaks down the hard, hard saline-alkali soil, and under the transport of the guide channel, pushes the soil on both sides of the ditch towards the center line, guiding the soil on both sides to initially fill the ditch, forming a primary backfill. Combined with the secondary backfill of the ditch by the subsequent rotary tillage mechanism, the filling firmness of the ditch is further improved, ensuring that the soil above the rat trail will not collapse and preventing seeds from being washed into the rat trail.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] Specific embodiments, such as Figure 1-2 As shown, this utility model provides an integrated ditching and seeding machine for saline-alkali ground squirrel trails, including a frame and a ditching mechanism mounted on the frame. A rotary tillage mechanism and a seeder are sequentially added behind the ditching mechanism on the frame. The ditching mechanism is connected to the frame by means of a plow blade and penetrates deep into the soil. The rotary tillage end of the rotary tillage mechanism and the seeding end of the seeder are located on the soil surface. The travel trajectories of the rotary tillage mechanism and the seeder coincide with the travel trajectory of the ditching mechanism. The ditching mechanism forms trenches between the soil surface and the squirrel trails. The soil around the trenches is broken up and backfilled by means of the rotary tillage mechanism.

[0023] During the construction of rodent tunnels, due to the operational characteristics of the trenching equipment, loose, low-salt gullies connected to the rodent tunnels are formed on the soil surface. After filling, these gullies can serve as sowing strips, which is beneficial for crop germination and growth. However, there is currently no integrated machine for rodent tunnel installation and sowing. Furthermore, when the seeder 2 sows in saline-alkali land with rodent tunnels, the seeds released by the seeder 2 are very likely to fall into the rodent tunnels due to the presence of gullies, resulting in seed waste.

[0024] Therefore, the integrated machine in this utility model achieves integrated operation of rat tunnel ditching, ditch backfilling and sowing through the cooperation between the ditching mechanism, rotary tillage mechanism and seeder 2, avoiding seeds falling into the rat tunnel, improving the planting efficiency of saline-alkali land, and only requiring one operation, reducing damage to the soil morphology, avoiding excessive soil compaction, and making it less likely to cause rat tunnel collapse.

[0025] Instruction manual attached Figure 1 , 2 The arrow in the diagram indicates the forward direction of frame 1.

[0026] During operation, after the trenching shovel 3 forms a trench between the soil surface and the rat trail, the rotary tillage mechanism behind it immediately breaks up and refines the soil on both sides of the trench and backfills the broken soil into the trench, thus sealing the trench directly above the rat trail and providing planting space for subsequent sowing.

[0027] like Figure 1-2 As shown, the trenching mechanism includes a trenching shovel 3 and a sizing device 4 disposed at the tail of the trenching shovel 3. The trenching shovel 3 forms the trenching end of the trenching mechanism. The trenching shovel 3 is fixedly connected to the front end of the frame 1 by means of a plow blade 5. The cutting ends of the plow blade 5 and the cutting ends of the trenching shovel 3 are both facing the forward direction of the frame 1. The sizing device 4 has a bullet-shaped structure, and the small-diameter end of the sizing device 4 faces the forward direction of the frame 1.

[0028] The trenching shovel 3 breaks the soil to form an initial trench. The bullet-shaped perforator 4 at the tail squeezes the soil through its small diameter end, forming a smooth rat tunnel in the deep layer that connects to the drainage channel. At the same time, the squeezing action of the perforator 4 makes the inner wall of the rat tunnel compact, enhancing its resistance to collapse and ensuring the long-term effectiveness of the salt drainage channel.

[0029] The plow blade 5 serves to connect to the trenching shovel 3. The blade-shaped design at the front end of the plow blade 5 can cut into the saline-alkali soil, and together with the soil-breaking end of the trenching shovel 3, it reduces the trenching resistance.

[0030] like Figure 1 As shown, a reinforcing rib 6 is also connected between the waist of the plow blade 5 and the bottom of the frame 1. The plow blade 5, the frame 1, and the reinforcing rib 6 together form a triangular support structure.

[0031] Saline-alkali soil is hard, and traditional plow blades 5 are prone to breakage due to repeated impacts. Therefore, a reinforcing rib 6 is connected to the bottom of the frame 1 at the waist of the plow blade 5 to form a triangular support to enhance the stability of the plow blade 5 structure. The triangular structure has high stability and prevents the plow blade 5 from deforming or even breaking during the soil breaking process.

[0032] like Figure 1-3As shown, a backfill shovel 7 is also provided on the back side of the plow blade 5. The backfill shovel 7 is located between the plane at the bottom of the rotary tillage end of the rotary tillage mechanism and the plane at the top of the furrowing shovel 3. The backfill shovel 7 has an isosceles triangular sheet structure. The backfill shovel 7 is set in the horizontal direction and the apex of the backfill shovel 7 faces the backward direction of the frame 1. The waist side of the backfill shovel 7 is folded to form a gathering wing 8. The gathering wing 8 is symmetrically arranged on both sides of the center line of the backfill shovel 7. The soil on both sides of the furrow is gathered towards the furrow by the gathering wing 8 to form backfill.

[0033] The folding structure of the converging wing 8 forms a guide channel that is wide at the front and narrow at the back. The front end of the converging wing 8 cuts and breaks down the hard, saline-alkali soil, and under the transport of the guide channel, pushes the soil on both sides of the ditch toward the center line, guiding the soil on both sides to initially fill the ditch, forming a primary backfill. Combined with the secondary backfilling of the ditch by the subsequent rotary tillage mechanism, the filling firmness of the ditch is further improved, ensuring that the soil above the rat trail will not collapse and preventing seeds from being washed into the rat trail.

[0034] like Figure 1-2 As shown, the rotary tillage mechanism includes a rotary tillage shaft 9 and rotary tillage components disposed on the rotary tillage roller. The rotary tillage components include rotary tillage blades 10 arranged symmetrically in a figure-eight shape. At least three sets of rotary tillage components are disposed along the axial direction of the rotary tillage shaft 9. The middle rotary tillage component forms the rotary tillage end of the rotary tillage mechanism. The adjacent rotary tillage components are symmetrically disposed on both sides of the middle rotary tillage component. The included angle between adjacent rotary tillage components along the axial direction of the rotary tillage shaft 9 is 90°. The vertical plane of the rotary tillage blade 10 on the inner side of the adjacent rotary tillage component passes through the rotary tillage blade 10 on the outer side of the middle rotary tillage component.

[0035] In this invention, the central rotary tillage component of the rotary tillage mechanism directly acts on the furrow area, crushing and cutting it apart, and mixing the soil in that area to fill the furrow. Simultaneously, the edge rotary tillage components cover both sides of the furrow, using the soil at the edges to replenish the soil in the central furrow. The staggered trajectory of the rotary tillage blades 10 ensures no areas are missed during backfilling, especially in cases of severe compaction of saline-alkali soil; multi-angle crushing can refine large clumps of soil to a suitable particle size range for backfilling.

[0036] like Figure 1-2 As shown, the rotary tillage mechanism also includes a rotary tillage press wheel 11, which is located behind the rotary tillage end of the rotary tillage mechanism. The rotary tillage press wheel 11 and the rotary tillage end of the rotary tillage mechanism are arranged collinearly along the forward direction of the frame 1.

[0037] The rotary tillage roller 11 is set coaxially with the rotary tillage end, and compacts the soil immediately after rotary tillage and backfilling. The gravity of the roller can eliminate voids in the soil, making the backfill soil layer compact and flat, providing a stable base for sowing. At the same time, compacting the soil can also reduce water evaporation and inhibit salt from rising to the surface with water.

[0038] like Figure 1-2 As shown, the seeder 2 includes a seed box 13 fixed on the frame 1 and a traveling wheel 14. The seed box 13 is provided with a seeding port 15 and forms the seeding end of the seeder 2. A seed dispensing shaft that closes the seeding port 15 is rotatably connected to the seed box 13. The seed dispensing shaft is connected to the axle of the traveling wheel 14. The seed dispensing shaft is provided with a groove for accommodating seeds. The seed dispensing shaft rotates with the help of the traveling wheel 14 and conveys the seeds in the groove to the seeding port 15 for discharge.

[0039] During sowing, the frame 1 moves forward, the traveling wheels 14 rotate accordingly and drive the seed metering shaft to rotate. The grooves on the seed metering shaft quantitatively hold the seeds, and during the rotation, the seeds are pushed to the sowing port 15 for discharge.

[0040] like Figure 1-2 As shown, the seeder 2 also includes a seeding press wheel 12, which is located behind the seeding end of the seeder 2. The seeding press wheel 12 and the seeding end of the seeder 2 are arranged colinearly along the forward direction of the frame 1.

[0041] The sowing and compaction roller 12 performs secondary compaction of the soil after sowing, further eliminating soil voids that may have occurred during sowing. Compacted soil reduces moisture evaporation, providing a moist environment for seeds, which is especially crucial in arid and saline-alkali lands.
