Description

Technical Field

[0001] The utility model relates to the technical field of dry field farming machinery, in particular to a dry field saline-alkali land improvement farming agricultural machinery. Background Art

[0002] Soil compaction in saline-alkali paddy fields is caused by the long-term strong influence of sodium and carbonate ions on saline-alkali soil, which changes the soil structure. The gaps between soil particles gradually decrease due to the increase in salt porosity, resulting in the formation of a hard crust layer on the soil surface, called soil compaction. This is very common in salt-alkali mutual exclusion systems. Soil compaction has a great impact on the cultivation and water permeability of rice fields. Therefore, a tillage machine is needed to perform soil turning operations.

[0003] According to a soil loosening device for fertilizing saline-alkali paddy fields disclosed in patent application number 202321301684.X, the device includes an agricultural vehicle, a commutator and a frame, and also includes a spiral cutter, b spiral cutter and a hydraulic push rod.

[0004] Although the above patent provides a set of soil loosening mechanism to enable farmers to better fertilize the saline-alkali rice fields and make the fertilizer better penetrate into the soil, the double spiral blade can be used to spirally cut and push the surface of the saline-alkali rice field soil, which helps to loosen the soil surface. However, due to the distribution of salt in the soil in the saline-alkali land, there is more salt in the surface layer and less in the lower layer, and the above technical patent directly plows and pushes the soil, which easily causes the soil in the surface layer to turn up, affecting the yield of rice planting in subsequent rice fields. For this reason, we provide a dryland saline-alkali land improvement tillage agricultural machinery to solve this problem. Utility Model Content

[0030] One side of the tilling mechanism 5 is connected with a crushing mechanism 6. The crushing mechanism 6 is in transmission connection with the engine 4. The crushing mechanism 6 includes two fixed seats 61 and a support plate 64 installed on the outside of the U-shaped frame 51. A transmission shaft 62 is rotatably connected between the fixed seats 61. A third pulley 63 is installed on the outside of the transmission shaft 62. A second belt 10 is sleeved together between the third pulley 63 and the second pulley 9. A second bevel gear 615 is installed on the outside of the transmission shaft 62. A first bevel gear 614 is meshed with the outside of the second bevel gear 615. A fixed shaft 610 is installed in the middle of the first bevel gear 614. A support frame 69 is installed on the upper end of the support plate 64 and is rotatably connected thereto. Square grooves 65 are symmetrically arranged on the upper end of the support plate 64. Crushing components 66 are movably arranged in the inner cavities of the square grooves 65. A gear 67 is rotatably connected to the upper end of the support plate 64 through a support shaft.

A leather pad 668 is sleeved on the outside of the steel needles 667.

[0032] After the engine 4 is started, the output end of the engine 4 drives the second pulley 9 to rotate. The second pulley 9 drives the third pulley 63 to rotate through the second belt 10. Further, the third pulley 63 drives the transmission shaft 62 and the second bevel gear 615 to rotate. The second bevel gear 615 synchronously drives the first bevel gear 614 and the fixed shaft 610 to rotate. The fixed shaft 610 drives the cam 612 and the fixed column 613 to rotate. While the fixed column 613 rotates, it pushes the fixed frame 68 to reciprocate in the inner cavity of the fixed frame 68. The fixed frame 68 drives a toothed plate 661 to reciprocate. This toothed plate 661 drives the gear 67 to rotate. The gear 67 drives another toothed plate 661 to reciprocate. Further, the two toothed plates 661 drive the support rod 663 and multiple steel needles 667 to reciprocate and swing through the connecting block 662, which is convenient for reciprocatingly sweeping and crushing the soil plowed by the tilling mechanism 5, effectively improving the soil loosening effect, and avoiding directly turning and pushing the soil to be crushed, resulting in the soil with more saline-alkali components that was over-tilled to the lower surface being turned up again, affecting the subsequent rice planting yield. When the toothed plate 661 drives the connecting block 662 to reciprocate, the connecting block 662 stably slides in the inner cavity of the concave plate 664 through the arc-shaped block 665, effectively improving the moving stability of the toothed plate 661. And the steel needle 667 is screwed with the thread groove 666, which is convenient for assembly, disassembly, maintenance and replacement. And through the design of the leather pad 668, the screwing firmness of the steel needle 667 is effectively improved.

[0033] Working principle: When the utility model is in use, by starting the engine 4, the output end of the engine 4 drives the first pulley 7 to rotate. The first pulley 7 drives the fourth pulley 34 and the connecting shaft 32 to rotate through the first belt 8. The connecting shaft 32 drives the two moving wheels 33 to rotate, facilitating the mobile operation of this device. The two curved plows 57 of the tilling mechanism 5 perform soil turning operation on the saline-alkali dry farmland, turning the surface soil containing more saline-alkali components to the bottom of the plough layer and turning the soil with less salt content in the lower layer to the surface, which is convenient for effectively controlling soil salt return and is beneficial to rice planting. The fixing plate 56 at the upper end of the curved plow 57 is clamped in the clamping groove 52 through the clamping plate 53 and is screwed with a nut 55 after passing through the U-shaped frame 51 by the threaded column 54, which is convenient for firmly installing the curved plow 57 and is also convenient for disassembly, maintenance and replacement, and is easy to use. When the tilling mechanism 5 completes the soil turning operation, the output end of the engine 4 drives the second pulley 9 to rotate. The second pulley 9 drives the third pulley 63 to rotate through the second belt 10. Then the third pulley 63 drives the transmission shaft 62 and the second bevel gear 615 to rotate. The second bevel gear 615 synchronously drives the first bevel gear 614 and the fixed shaft 610 to rotate. The fixed shaft 610 drives the cam 612 and the fixed column 613 to rotate. While the fixed column 613 rotates, it pushes the fixed frame 68 to move reciprocally in the inner cavity of the fixed frame 68. The fixed frame 68 drives a toothed plate 661 to move reciprocally. This toothed plate 661 drives the gear 67 to rotate. The gear 67 drives the other toothed plate 661 to move reciprocally. Then the two toothed plates 661 drive the support rod 663 and multiple steel needles 667 to swing reciprocally through the connecting block 662, which is convenient for reciprocally sweeping and crushing the soil tilled by the tilling mechanism 5, effectively improving the soil loosening effect, and avoiding directly turning, pushing and crushing the soil, resulting in the soil with more saline-alkali components in the surface layer that has been over-tilled and turned up again, affecting the subsequent rice planting yield. When the toothed plate 661 drives the connecting block 662 to move reciprocally, the connecting block 662 stably slides in the inner cavity of the concave plate 664 through the arc-shaped block 665, effectively improving the moving stability of the toothed plate 661. The steel needle 667 is screwed with the threaded groove 666, which is convenient for assembly, disassembly, maintenance and replacement. By designing the leather pad 668, the screwing firmness of the steel needle 667 is effectively improved.
