Description

Technical Field

[0001] The present invention relates to soil turning equipment, in particular to intelligent soil turning equipment for saline-alkali land cultivation applied in the technical field of agricultural machinery. Background Art

[0002] Saline-alkali land refers to land with excessive soluble salts in the soil, which mainly include sodium chloride and sodium sulfate, and which inhibit or poison the growth of most crops. Cultivation of saline-alkali land is extremely difficult and requires scientific improvement and special measures. If saline-alkali land is to be used for agricultural cultivation, it must first be comprehensively improved with the goal of reducing soil salt content, improving soil physical structure, regulating pH value, and increasing soil fertility.

[0003] The specification of Chinese patent CN113424669A discloses "A portable soil turning device for planting oats in saline-alkali land". Through the cooperation of a rake, a driving assembly, a mounting assembly and a pulling assembly, the rake can be automatically inserted into the ground, and then the soil turning work can be completed by manually rotating the mounting frame, saving time and effort. The specification of Chinese patent CN216626559U discloses "A planting device for improving saline-alkali land soil". Through the setting of the soil turning assembly, the saline-alkali land soil on the ground can be turned over, and the medicine is replenished through the water pump, which not only plays a good role in soil turning and improves the planting effect, but also can timely fuse the turned saline-alkali land soil with the medicine, thereby improving the effect of saline-alkali land soil treatment. Moreover, through the setting of the soil turning assembly, it can also be adjusted according to the depth of soil turning, further improving the soil improvement effect of the planting device.

[0004] The process of tilling and turning over the saline-alkali land is often accompanied by scientific improvement of the saline-alkali soil. Most traditional scientific improvement methods of saline-alkali land are to apply a large amount of farmyard manure, return straw to the field, turn over green manure, etc. to increase organic matter and improve the structure, and apply chemical amendments to neutralize soil alkalinity and replace sodium ions. However, the applied organic matter and chemical amendments are directly mixed with the turned-over soil. This part of the mixed soil is mostly located in the surface layer of the saline-alkali land, that is, the soil layer used for crop planting. However, during the crop planting activities, the applied chemical amendments will also be lost, and the sodium ions in the deeper soil will rise to the soil surface. Therefore, it is necessary to repeatedly apply chemical amendments, and the improvement effect of the saline-alkali planting soil layer is insufficient. Summary of the Invention

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that during the crop planting process, the applied chemical modifiers will also be lost, and the sodium ions in the deeper soil will rise to the soil surface. Therefore, it is necessary to repeatedly apply the chemical modifiers, and the improvement effect of the saline-alkali land planting soil layer is insufficient.

[0006] To solve the above problems, the present invention provides an intelligent soil turning device for saline-alkali land cultivation, comprising a device body, a flip bracket hingedly connected to the rear of the device body, equidistantly arranged turning buckets fixedly connected to the middle of the flip bracket, the turning buckets filled with chemical improvers, and a leakage outlet opened at the bottom tip of the turning bucket, a harrow shaft rotatably connected to the bottom of the harrow shaft, equidistantly arranged disc harrow wheels fixedly connected to the outside of the harrow shaft, the disc harrow wheels alternately distributed between two adjacent turning buckets, and the bottom ends of the disc harrow wheels are higher than the bottom tips of the turning buckets;

[0007] The top of the leakage outlet is rotatably connected to a compacting wheel, the thickness of the compacting wheel is smaller than the thickness of the bottom tip of the plow bucket, the circumferential outer ring of the compacting wheel is provided with an outer wheel ring, and the left and right ends of the outer wheel ring are fixedly connected to the left and right ends of the compacting wheel with connecting membrane rings, the radial surface of the outer wheel ring is V-shaped, and the outer wheel ring is made of spring steel sheet.

[0008] In the above-mentioned intelligent tillage equipment for saline-alkali land cultivation, the saline-alkali land is deep-plowed by the plow bucket, and chemical improvers are laid in the deep grooves plowed through the leakage outlet, and the laid chemical improvers are compacted by the compaction wheel, which effectively inhibits the sodium ions in the deep soil layer from rising to the soil surface, effectively reduces the impact of surface planting activities on chemical improvers, effectively reduces the loss of chemical improvers, and effectively improves the planting soil layer of the saline-alkali land.

[0009] As a further improvement of the present application, the connecting membrane ring is arranged in an outward bulging state, and the connecting membrane ring is made of wear-resistant rubber material, which facilitates the outward bulging deformation of the connecting membrane ring and effectively improves the service life of the connecting membrane ring.

[0010] As a further improvement of the present application, elastic ribs are fixedly connected between the middle part of the outer wheel ring and the circumferential surface of the compacting wheel. The elastic ribs are made of spring steel sheets and are curved in an arc shape. The elastic ribs are used to effectively improve the deformation buffering capacity between the outer wheel ring and the compacting wheel, facilitate the expansion deformation of the outer wheel ring, and facilitate the shape restoration of the outer wheel ring.

[0011] As a further improvement of the present application, the chemical improver is made of a mixture of gypsum, phosphogypsum and sulfur. The internal rotation of the plow bucket is connected to a spiral push shaft, and the top rotation of the flip bracket is connected to a linkage shaft. The top of the spiral push shaft and the outside of the linkage shaft are fixedly connected with bevel gears. The two bevel gears are meshed and connected, and the chemical improver is pushed to move in the plow bucket through the spiral push shaft, which effectively improves the discharge effect of the chemical improver from the leakage port, and through the meshing connection of the bevel gears, the linkage shaft connects multiple spiral push shafts in series, which facilitates the synchronous rotation of the spiral push shafts.

[0012] As another improvement of the present application, the linkage shaft and the rake shaft are fixedly connected to the outside with transmission wheels, and a transmission chain is provided between the two transmission wheels. The transmission between the transmission wheels is realized through the transmission chain, which facilitates the rake shaft to drive the linkage shaft to rotate.

[0013] As another improved supplement to the present application, the bottom end of the spiral pushing shaft is fixedly connected with an extension whip rib, which extends through the leakage outlet, and the bottom end of the extension whip rib is curved and extends to the bottom front end of the compacting wheel. The extension whip rib extending out of the leakage outlet rotates with the spiral pushing shaft, effectively avoiding blockage of the leakage outlet, and the rotating extension whip rib stirs the chemical amendment and soil to mix, effectively improving the laying effect of the chemical amendment.

[0014] As another improved supplement to the present application, the bottom end of the extended whip reinforcement is evenly fixedly connected with a twisted wire. The extended whip reinforcement is made of steel wire rope, and the twisted wire is made of stainless steel wire. The twisted wire effectively increases the stirring radius of the extended whip reinforcement, thereby effectively improving the mixing effect of the chemical amendment and the soil.

[0015] In summary, the present invention is used to till the saline-alkali land by deep plowing the saline-alkali land through a plow bucket, and the chemical improver in the plow bucket leaks out through the leakage port, and the chemical improver is laid in the deep groove plowed, and then the laid chemical improver is rolled by the outer wheel ring on the compacting wheel, and the outer wheel ring is flattened due to the pressure, thereby effectively increasing the pressing area of ​​the chemical improver and effectively increasing the laying width area of ​​the chemical improver. Subsequently, the disc harrow wheel crushes the soil blocks plowed out by deep plowing, and lays the crushed soil on top of the chemical improver to realize the burial of the chemical improver, effectively reducing the impact of planting activities on the soil surface on the chemical improver, and effectively reducing the loss of the chemical improver. The chemical improver that neutralizes the alkalinity of the soil effectively inhibits the sodium ions in the deep soil layer from rising to the soil surface, thereby effectively improving the planting soil layer of the saline-alkali land.

DETAILED DESCRIPTION

[0027] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figures 1 to 3 The figure shows an intelligent soil turning device for cultivating saline-alkali land, comprising a device body 1, a flip bracket 101 hingedly connected to the rear of the device body 1, a equidistantly arranged turning bucket 102 fixedly connected to the middle of the flip bracket 101, the interior of the turning bucket 102 is filled with a chemical improver, and a leakage port 103 is opened at the bottom tip of the turning bucket 102, a harrow shaft 104 is rotatably connected to the bottom of the harrow shaft 104, and equidistantly arranged disc harrow wheels 105 are fixedly connected to the outside of the harrow shaft 104, and the disc harrow wheels 105 are alternately distributed between two adjacent turning buckets 102, and the bottom ends of the disc harrow wheels 105 are higher than the bottom tips of the turning buckets 102;

[0030] When turning over the saline-alkali land, the device is dragged by a traction device to drive the plow bucket 102 to deep-plow the saline-alkali land. Deep grooves are generated during the deep plowing process, and the chemical improver in the plow bucket 102 leaks out through the leakage port 103. The chemical improver is laid in the deep-plowed grooves. The disc harrow wheel 105 then crushes the clods of soil that have been plowed. Since the bottom end of the disc harrow wheel 105 is higher than the bottom tip of the plow bucket 102, the crushing action of the disc harrow wheel 105 does not affect the laid chemical improver, and the crushed soil is laid on top of the chemical improver, so that the chemical improver is buried deep in the soil, effectively reducing the impact of planting activities on the soil surface on the chemical improver, effectively reducing the loss of the chemical improver, and realizing that the chemical improver that neutralizes the alkalinity of the soil effectively inhibits the sodium ions in the deep soil layer from rising to the soil surface, thereby effectively improving the planting soil layer of the saline-alkali land.

[0031] Figures 3 to 5 As shown, the top of the leakage outlet 103 is rotatably connected to the compacting wheel 2, the thickness of the compacting wheel 2 is less than the thickness of the bottom tip of the plow bucket 102, the circumferential outer ring of the compacting wheel 2 is provided with an outer wheel ring 201, and the left and right ends of the outer wheel ring 201 are fixedly connected to the left and right ends of the compacting wheel 2 with a connecting membrane ring 202, the radial surface of the outer wheel ring 201 is V-shaped, and the outer wheel ring 201 is made of spring steel sheet, the connecting membrane ring 202 is set in an outward bulge state, and the connecting membrane ring 202 is made of wear-resistant rubber material The outer drum deformation of the connecting membrane ring 202 is facilitated, and the service life of the connecting membrane ring 202 is effectively improved. An elastic rib 203 is fixedly connected between the middle part of the outer ring 201 and the circumferential surface of the compacting wheel 2. The elastic rib 203 is made of spring steel sheets, and the elastic rib 203 is curved in an arc shape. The elastic rib 203 is used to effectively improve the deformation buffering capacity between the outer ring 201 and the compacting wheel 2, which is convenient for the expansion deformation of the outer ring 201 and the shape restoration of the outer ring 201.

[0032] When the chemical improver is laid in the deep furrows plowed by deep plowing, the compacting wheel 2 moves with the plow bucket 102. Since the compacting wheel 2 is installed behind the plow bucket 102 and is at the top of the leakage outlet 103, in order to avoid the compacting wheel 2 increasing the resistance of the plow bucket 102, the thickness of the compacting wheel 2 needs to be smaller than the width of the bottom tip of the plow bucket 102. The outer wheel ring 201 on the compacting wheel 2 rolls the laid chemical improver. During the rolling process, the outer wheel ring 201 undergoes a flat deformation due to pressure, that is, the V-shaped opening angle of the outer wheel ring 201 is larger, and the pressing area of ​​the chemical improver by the outer wheel ring 201 is larger, thereby achieving more comprehensive compaction of the chemical improver, effectively increasing the laying width area of ​​the chemical improver, and thereby effectively increasing the neutralization reaction area of ​​the chemical improver.

[0033] Second implementation method:

[0034] Compared with the first embodiment, the chemical modifier applicable to this embodiment is a solid modifier made from a mixture of gypsum, phosphogypsum and sulfur. A spiral push shaft 3 and an extension whip rib 305 are newly added. The specific newly added structure is as follows, and the remaining structure is consistent with the first embodiment.

[0035] Figures 6 to 8 The top of the tilting bracket 101 is rotatably connected to the linkage shaft 301, and the top of the spiral pushing shaft 3 and the outside of the linkage shaft 301 are fixedly connected with a bevel gear 302. The two bevel gears 302 are meshed and connected, and the chemical improver is pushed to move in the tilting bucket 102 through the spiral pushing shaft 3, which effectively improves the discharge effect of the chemical improver from the leakage port 103. Moreover, the meshing connection of the bevel gears 302 enables the linkage shaft 301 to connect multiple spiral pushing shafts 3 in series, which is convenient for the synchronous rotation of the spiral pushing shafts 3. The outside of the linkage shaft 301 and the rake shaft 104 are fixedly connected with a transmission wheel 303, and a transmission chain belt 304 is provided between the two transmission wheels 303. The transmission between the transmission wheels 303 is realized by the transmission chain belt 304, which is convenient for the rake shaft 104 to drive the linkage shaft 301 to rotate.

[0036] The chemical amendment filled in the plow bucket 102 is a solid mixture of gypsum, phosphogypsum, and sulfur. Gypsum is the core material for saline-alkali land improvement. The preferred ratio for moderate saline-alkali land is: 50-70 parts of gypsum and phosphogypsum + 20-30 parts of humic acid + 5-10 parts of aluminum sulfate; alkaline soil requires the addition of sulfur, and the ratio can be: 45-60 parts of gypsum and phosphogypsum + 5-10 parts of sulfur + 20-30 parts of humic acid + 5-10 parts of aluminum sulfate to enhance acidification capacity; inland soda saline-alkali soil requires additional organic materials in the formula. The actual ratio needs to be dynamically adjusted based on soil salinity, crop type, and moisture conditions, and attention should be paid to the long-term environmental safety of the amendment. Those skilled in the art can adjust the ratio according to the actual situation of the saline-alkali land.

[0037] During the rolling of the disc harrow wheel 105, the transmission between the transmission wheels 303 is realized through the transmission chain belt 304, so that the harrow shaft 104 drives the linkage shaft 301 to rotate, and then through the meshing connection of the bevel gear 302, the linkage shaft 301 drives multiple spiral push shafts 3 in series, synchronously driving the multiple spiral push shafts 3 to rotate, so that the chemical improver in the plow bucket 102 is discharged from the leakage port 103.

[0038] Figure 7 and Figure 9As shown, the bottom end of the spiral pushing shaft 3 is fixedly connected with an extension whip rib 305, which extends through the leakage outlet 103, and the bottom end of the extension whip rib 305 is curved and extends to the bottom front end of the compacting wheel 2. The extension whip rib 305 extending from the leakage outlet 103 rotates with the spiral pushing shaft 3, effectively avoiding blockage of the leakage outlet 103, and the rotating extension whip rib 305 stirs the chemical amendment and the soil to mix, effectively improving the laying effect of the chemical amendment. The bottom end of the extension whip rib 305 is evenly fixedly connected to the outside with a twisted wire 306, the extension whip rib 305 is made of steel wire rope, and the twisted wire 306 is made of stainless steel wire. The twisted wire 306 effectively increases the stirring radius of the extension whip rib 305, thereby effectively improving the mixing effect of the chemical amendment and the soil.

[0039] When the spiral pushing shaft 3 rotates to push the solid chemical modifier in the spiral pushing shaft 3 to move toward the leakage outlet 103, the spiral pushing shaft 3 synchronously drives the extended whip rib 305 to rotate, and the rotating extended whip rib 305 stirs the leakage outlet 103, effectively avoiding the blockage of the leakage outlet 103, that is, breaking up the lumps, and the chemical modifier discharged from the leakage outlet 103 continues to be affected by the stirring of the extended whip rib 305. The twisted wire 306 on the extended whip rib 305 effectively increases the stirring radius, realizes the mixing of the chemical modifier and the soil, effectively improves the dispersed laying of the chemical modifier, effectively reduces the accumulation of the chemical modifier, and thus effectively improves the neutralization reaction effect of the chemical modifier and the soil.

[0040] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
