Description

Technical Field

[0002] The sowing device and fertilizer device of the wheat seeder are mainly used to fertilize and sow the land. First, a furrow opener will be used to dig furrows in the soil. The fertilizer pipe will enter the furrow opener and start to fertilize the opened furrows. Then the sowing device will start to sow seeds into the land. The pressing wheel will then loosen and compact the soil in the furrow, thereby completing the wheat sowing operation.

[0003] The furrow opener is one of the main working parts of the seeding and fertilizing machine. It can open a trench of a certain depth to guide the fertilizer to fall in. Therefore, the actual furrowing depth of the furrow opener will directly affect the quality of fertilization. When the furrow opener is digging a trench in wet and rotten soil, it is difficult for the furrow opener to push the object aside when encountering a hard object. Under the action of sticky soil, after the furrow opener turns over the furrowing, the hard object will still be located inside the furrow. In addition, when the soil is too wet and rotten, after the furrow is opened, due to the action of soil flow, part of the soil will flow back into the furrow.

[0004] If the above situation occurs, the amount of fertilizer applied is still executed according to the originally set parameters, which will result in the batch of fertilizer not reaching the corresponding trenching depth. In this case, the amount of fertilizer applied can be increased to ensure the fertilization effect. However, how to intelligently and accurately adjust the amount of fertilizer applied according to the actual trenching conditions has become an urgent problem to be solved by people in this field.

By starting the second driving member 101 and the screw nut structure, the height position of the second bracket 9 is adjusted to determine the trenching depth. When the trenching depth adjustment is completed, the two ends of the second bracket 9 are connected to the seeder through bolt connectors to improve the trenching stability;

[0048] A plurality of first connecting plates 12 and second connecting plates 13 are sequentially interspersed on the lower surface of the second bracket 9. The third bracket 11 is fixedly inserted into the interior of the first connecting plates 12 and the second connecting plates 13. The interior of the third bracket 11 is fixedly connected to a fixing column 14. The lower end of the fixing column 14 is fixedly connected to a connecting block 16. The front end of the connecting block 16 is fixedly connected to a furrowing knife 15. The furrowing knife 15 first determines the furrowing depth under the movement of the depth adjustment component 10, and then the furrowing knife 15 furrows the land under the drive of the seeder.

[0049] A discharge valve is provided at the bottom of the fertilizer box 2, and the discharge valve is connected to a discharge pipe 23. The discharge pipe 23 is a metal telescopic tube. A discharge cavity 31 is provided on one side of the connecting block 16 close to the discharge pipe 23. The discharge cavity 31 is connected to the other end of the discharge pipe 23. When the trenching knife 15 is trenching, the discharge valve is opened, and the fertilizer enters the discharge pipe 23 through the discharge valve and is discharged from the discharge cavity 31, thereby realizing the synchronization of trenching and fertilizing.

[0050] The intelligent discharge assembly includes a telescopic rod 25, which is preferably but not limited to an electric telescopic rod. A fourth bracket 24 is fixedly connected between the top of the telescopic rod 25 and the trenching knife 15, and the output end of the telescopic rod 25 is fixedly connected to a fixed tube 26.

One end of the mobile tube 27 located in the fixed tube 26 is connected to the fixed tube 26 by a spring, and a sealed cavity is formed. The interior of the cavity is filled with liquid. A regulating disk 34 is provided on one side of the connection block 16 near the upper end of the discharge cavity 31. A partial annular groove is provided inside the regulating disk 34. A moving block 37 is slidably connected inside the partial annular groove. A through hole 38 consistent with the diameter of the discharge cavity 31 is provided in the middle of the moving block 37. Figure 7 , which is the initial material flow state of the discharge cavity 31 and the through hole 38. An extrusion cavity 36 and a control cavity are respectively provided between the two sides of the moving block 37 and the interior of the local annular chute. A transmission pipe 29 is connected between the interior of the extrusion cavity 36 and the sealed cavity in the fixed tube 26. The interior of the extrusion cavity 36 is filled with liquid, and a pressure balance state is formed between the liquid in the sealed cavity in the initial material flow state. An extrusion spring is provided on the inner wall of the extrusion cavity 36, and the other end of the extrusion spring is connected to the connecting moving block 37.

[0051] In this embodiment, the depth adjustment component 10 pre-adjusts the trenching depth, the first driving member 3 is started with the initial operating power, and the amount of hot air entering is controlled according to the humidity of the fertilizing environment. Specifically, the first humidity limit H1 and the second humidity limit H2 are pre-set, wherein the humidity limit is set according to different regions. When the humidity of the fertilizing environment is lower than the first humidity limit H1, the hot air flow is not introduced to dry the fertilizer. When the humidity of the fertilizing environment is between the first humidity limit H1 and the second humidity limit H2, the hot air flow is introduced, the air pump operates at the initial set power P, and the heating part 8 operates at the initial set temperature T. When the humidity of the fertilizing environment is higher than the second humidity limit H2, the air pump operates at the power 2P and the heating part 8 still operates at the initial set temperature T, to ensure sufficient airflow, and perform multi-stage stirring and dehumidification treatment on the fertilizer in the fertilizer box 2 to improve the discharge quality of the fertilizer.

[0052] After completing the above stirring and dehumidifying process settings, the trenching process is started, the discharge valve is opened, and the trenching knife 15 performs the trenching process of the set trenching depth on the land. The test ball 28 is flush with the bottom of the trenching knife 15 to detect whether the actual trenching depth reaches the preset requirement. When the actual trenching depth reaches the preset requirement, the test ball 28 is not subjected to pressure. After the trenching knife 15 completes trenching, the fertilizer in the fertilizer box 2 is discharged to the trenching through the discharge pipe 23 and the discharge cavity 31 and the through hole 38 in the initial material passing state. When the land at the trenching location is affected by the backflow of hard rocks or clay and a bulge appears, resulting in the actual trenching depth not reaching the preset requirement, the test ball 28 will be subjected to the upward squeezing force of the bulge. The test ball 28 applies an upward squeezing force to the sealing cavity through the moving tube 27, and the spring is compressed, so that the liquid in the sealing cavity enters the extrusion cavity 36 through the transmission tube 29, and the extrusion spring is stretched. Figure 7 The movable block 37 in the middle rotates counterclockwise by a corresponding angle, so that the area where the discharge cavity 31 and the through hole 38 communicate becomes larger, thereby increasing the amount of fertilizer discharged. On the one hand, the amount of fertilizer applied to the land that has not reached the furrowing depth is accurately increased to ensure sufficient fertilizer. On the other hand, it helps farmers to clearly understand the fertilization situation during the subsequent land inspection and adjust the subsequent sowing method to ensure the sowing quality of wheat.

[0053] When the trench where the test ball 28 passes reaches the set trench depth again, the test ball 28 is no longer subjected to the upward extrusion force. Under the action of the spring and the rebound of the extrusion spring, the liquid that originally entered the extrusion chamber 36 returns to the sealed chamber through the transmission pipe 29, and the discharge volume returns to the original setting. Through the setting of the intelligent discharge component, when discharging fertilizer through trenching, the discharge volume will be accurately controlled according to the actual situation of the trenching depth, and the fertilizer discharge state can be automatically adjusted to realize intelligent fertilization operation.

[0054] It should be noted that the situation in this application where the actual trenching depth does not reach the set trenching depth is when the amount of fertilizer is adjusted while allowing deviations, and does not include the situation where the actual trenching depth does not meet the requirements for fertilizer at all.

[0055] In the second embodiment, on the basis of the first embodiment, a limit plate 40 is provided on the inner wall of the control cavity, and the limit plate 40 is used to limit the movable block 37. A limit switch 39 is provided on one side of the limit plate 40. An exhaust pipe 30 is provided inside the fixed column 14, and the air outlet of the exhaust pipe 30 is aligned with the test ball 28. The upper end of the exhaust pipe 30 is connected to a third air guide pipe 32, and a second control valve 35 is provided on the third air guide pipe 32. The second control valve 35 is fixedly provided on the second bracket 9. The third air guide pipe 32 is a telescopic tube. An inclined plate 33 is provided at the connection between the third air guide pipe 32 and the discharge pipe 23, which not only realizes effective ventilation, but also provides a discharge path for the discharged fertilizer to prevent blockage.

[0056] The limit switch 39 is electrically connected to a delay timer for controlling the start execution time of the second control valve 35;

[0057] In this embodiment, when the test ball 28 is squeezed by the protruding portion so that the discharge cavity 31 and the through hole 38 are completely connected, Figure 8 As shown, the moving block 37 touches the limit switch 39, so that the second control valve 35 is started and the air pump is controlled to operate at a power of 2P to 2.5P. While the original part of the airflow promotes the transmission of the fertilizer particles in the transmission pipe 29, part of the airflow is discharged through the third air guide pipe 32 and the exhaust pipe 30. The warm airflow is sprayed on the surface of the test ball 8 for a period of time, which plays a self-cleaning role and ensures the accuracy of the test ball 8 in detecting the protrusion.
