Description

Technical Field

[0001] This application belongs to the field of agricultural machinery, specifically relating to a self-traction drip irrigation integrated machine for corn tillage and sowing. Technical Background

[0002] Most farmland in Northwest China is alkaline. This conclusion is mainly based on the climate characteristics of Northwest China, namely low rainfall and high evaporation. Under these climatic conditions, salts tend to accumulate in the soil, making the soil alkaline or strongly alkaline. Therefore, it can be considered that most farmland in Northwest China is alkaline soil.

[0003] However, saline-alkali land refers to degraded soil with high salt content or alkalinity, poor soil structure, easy compaction, low organic matter content, poor nutrient content, and weak soil fertility retention capacity. These soil conditions pose a certain challenge to the growth and development of corn.

[0004] Therefore, when planting corn in saline-alkali land, it is necessary to apply fertilizer to balance the soil pH. Since corn requires a large amount of nitrogen, it is necessary to apply ammonium nitrogen fertilizer. It can provide corn with the necessary nitrogen nutrition, improve the soil salinity, promote the growth and development of corn, and increase yield and quality.

[0005] However, it should be noted that ammonium nitrogen fertilizers are prone to nitrogen volatilization when applied to saline-alkali soils. Therefore, existing technologies often employ measures such as deep application and thorough burial to reduce nitrogen volatilization losses. Applying ammonium nitrogen fertilizers to saline-alkali soils can effectively improve soil salinity, provide corn with necessary nitrogen nutrition, and promote plant growth and development.

[0006] In summary, the existing technology has the following problems:

[0007] Existing technologies often employ measures such as deep application and strict burial to reduce nitrogen volatilization loss in alkaline soils. While effective, a large amount of ammonium nitrogen fertilizer still reacts chemically with alkaline substances in the soil, resulting in a significant loss of nitrogen in the form of ammonia due to the chemical reaction of ammonium nitrogen fertilizer applied to alkaline soils. Summary of the Invention

[0008] The purpose of this application is to address the technical problem in the prior art where the application of ammonium nitrogen fertilizer to alkaline soil results in a chemical reaction that causes a large amount of nitrogen to be lost and dispersed in the form of ammonia.

[0013] Preferably, the hollow fertilizer distribution blade includes a hollow lower fertilizer pipe, a soil dividing head, and a fertilizer guiding pipe. The hollow lower fertilizer pipe is connected to the lower end of the second fertilizer box. The soil dividing head is located at the front end of the hollow lower fertilizer pipe and faces the traveling direction of the frame. The fertilizer guiding pipe is located on the soil dividing head, with one end connected to the hollow lower fertilizer pipe and the other end extending away from the traveling direction of the frame.

[0014] Preferably, the belt traction assembly includes a mounting rod, a mounting shell, a belt pulley assembly, and a driving component. The mounting rod is mounted on the frame, the mounting shell is located at the lower end of the mounting rod, and the mounting shell has an inclined belt inlet at one end near the soil entry assembly. The belt pulley assembly is rotatably mounted inside the mounting shell and close to the inclined belt inlet. The driving component is located in the mounting shell and is connected to the belt pulley assembly for transmission.

[0015] Preferably, the traction assembly further includes a positioning wheel set, which is disposed inside the mounting housing and away from the inclined belt inlet. The positioning wheel set includes a first positioning wheel and a second positioning wheel that are rotatably disposed inside the mounting housing, and a positioning outlet is formed between the first positioning wheel and the second positioning wheel.

[0016] Preferably, the belt traction assembly further includes a guide plate, which is disposed between the belt pulley assembly and the positioning pulley assembly, extending from the bottom of the mounting housing to the positioning outlet.

[0017] Preferably, the first fertilization mechanism includes a first fertilizer box and a plurality of fertilizer spreading troughs. The first fertilizer box is mounted on the frame, and the plurality of fertilizer spreading troughs are arranged at intervals and located at the lower end of the first fertilizer box, and are correspondingly arranged with a plurality of second fertilization components.

[0018] Preferably, the soil-entry assembly includes a hollow guide rod and a soil guide cover. The hollow guide rod is mounted on the frame, and the soil guide cover is mounted on the lower end of the hollow guide rod. The soil guide cover extends from the lower end of the hollow guide rod toward the traction assembly and has a spindle-shaped structure for guiding the soil.

[0019] Preferably, the device further includes a sowing mechanism disposed between the drip irrigation tape laying mechanism and the drip irrigation tape compaction mechanism. The sowing mechanism includes a first mounting frame and a plurality of seed metering components. The first mounting frame is disposed on the machine frame, and the plurality of seed metering components are disposed on the first mounting frame and are distributed at intervals along the direction perpendicular to the machine frame. The plurality of seed metering components and the plurality of pull belt traction components are arranged alternately.

[0020] Preferably, the seeding assembly includes a seed box and a duckbill planter. The duckbill planter is rotatably mounted on the first mounting frame, and the seed box is mounted on the duckbill planter and communicates with the duckbill planter.

[0021] The beneficial effects are as follows: This application includes a first fertilization mechanism for first applying a first type of fertilizer (phosphate fertilizer or potassium fertilizer) that can inhibit the escape of nitrogen through ammonia gas.

[0022] In the first stage: the second type of fertilizer (ammonium nitrogen fertilizer) is extruded through a fertilizer extrusion auger. The second type of fertilizer (ammonium nitrogen fertilizer) is extruded into the ground in strips with a certain cross-sectional area. The strips with a certain cross-sectional area can reduce the contact area between the underground ammonium nitrogen fertilizer and alkaline substances in the saline-alkali soil. This prevents most of the ammonium nitrogen fertilizer inside from coming into contact with alkaline substances for a period of time, so that most of the nitrogen element in the ammonium nitrogen fertilizer will not be lost for a period of time. In addition, during the process of the ammonia gas produced by the ammonium nitrogen fertilizer reacting with alkaline substances on the surface and escaping from the soil gaps, the ammonia gas will react with the first type of fertilizer (such as phosphate fertilizer or potash fertilizer) mixed in the soil. Therefore, only a small amount of nitrogen element is lost in the form of ammonia gas in this stage.

[0023] The second stage: After a period of time, when the second type of fertilizer inside reacts with the alkaline substance, the drip irrigation tape laid to a certain depth in the soil by the drip irrigation tape laying mechanism infiltrates the soil, so that the released ammonia gas dissolves in the water.

[0024] The corn tillage and sowing self-traction drip irrigation integrated machine of this application can deploy a water and fertilizer interaction system in one go. Through the above two stages, the nitrogen element of the second fertilizer is stabilized to the greatest extent in the alkaline soil. This achieves the effect of leaving the nitrogen element in the soil when a large amount of nitrogen element is lost in the form of ammonia gas during the application of nitrogen fertilizer in saline-alkali land.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The technical solutions of this application will be further described below with reference to the accompanying drawings of the embodiments, and this application is not limited to the following specific implementation methods.

[0035] It should be understood that the same or similar reference numerals in the accompanying drawings of the embodiments correspond to the same or similar components. In the description of this application, it should be understood that if terms such as "upper," "lower," "front," "rear," "left," "right," "top," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0036] Please refer to Figures 1 to 8 In one specific embodiment of this application, such as Figure 1 As shown, a corn tillage and sowing self-traction drip irrigation tape integrated machine includes: a frame 100 and a first fertilization mechanism 200, a rotary tillage mechanism 300, a second fertilization mechanism 400, a drip irrigation tape laying mechanism 500, a sowing mechanism 600 and a drip irrigation tape compaction mechanism 700 arranged sequentially on the frame 100.

[0037] The second fertilization mechanism 400 includes a second fertilizer box 410, a fertilizer extrusion auger 420, and a plurality of hollow fertilizer application blades 430. The second fertilizer box 410 is mounted on the frame 100. The fertilizer extrusion auger 420 is mounted inside the second fertilizer box 410. The plurality of hollow fertilizer application blades 430 are spaced apart in the second fertilizer box 410 along the non-traveling direction. The hollow fertilizer application blades 430 are connected to the second fertilizer box 410.

[0038] The drip irrigation tape laying mechanism 500 includes a drip irrigation tape take-up roller 510, a soil insertion component 520, and a tape pulling component 530. The drip irrigation tape take-up roller 510 is rotatably mounted on the frame 100. The soil insertion component 520 is spaced apart on the frame 100 along the non-walking direction. The tape pulling component 530 is correspondingly mounted to the soil insertion component 520.

[0039] In a specific implementation process, when planting corn on saline-alkali land, the first fertilization mechanism 200 first applies a first type of fertilizer to the soil. This first type of fertilizer is either potassium fertilizer or phosphate fertilizer, or any fertilizer that can react with ammonia or achieve nitrogen fixation through adsorption. Then, when the rotary tillage mechanism 300 tills the land, it simultaneously mixes the first type of fertilizer into the soil. The second type of fertilizer is any type of ammonium nitrogen fertilizer. Then, the fertilizer extrusion auger 420 extrudes the second type of fertilizer from the second fertilizer box 410 into the hollow cloth fertilizer blade. The hollow fertilizer application tool 430 applies a second type of fertilizer into the soil in strips with a specific cross-sectional area. When the ammonium nitrogen fertilizer subsequently reacts chemically with the alkaline substances in the saline-alkali soil, only the surface of the applied strip reacts with the alkaline substances. This reaction slowly releases ammonia gas, which then slowly seeps out through the soil pores. During the process of nitrogen loss, the ammonia in the soil pores reacts with the first fertilizer. The first fertilizer mixed into the soil can fix nitrogen in the ammonia that is slowly leaching from the soil pores. It will react chemically with the ammonia, fixing the nitrogen in the ammonia into the soil in the form of newly generated chemical substances, thus preventing some nitrogen loss. After the drip irrigation tape is connected to the main pipeline, the water that seeps into the soil through the drip irrigation tape can further absorb the ammonia. The seeping water and fertilizer dissolve the second fertilizer (ammonium nitrogen fertilizer), promoting the reaction rate of the second fertilizer (ammonium nitrogen fertilizer) with alkaline substances. At this time, a large amount of ammonia will be generated. However, the water will also promote the reaction between the ammonia and the first fertilizer in the soil. At the same time, the water and fertilizer have an absorption effect on ammonia. Therefore, when the second fertilizer (ammonium nitrogen fertilizer) is applied in saline-alkali land, it is still possible to prevent a large amount of nitrogen from being lost in the form of ammonia. Through the above process, most of the nitrogen in the ammonia is fixed, improving the utilization rate of the second fertilizer (ammonium nitrogen fertilizer) in saline-alkali land.

[0040] Secondly, the drip irrigation tape is guided into the soil by the soil entry component 520. The drip irrigation tape enters the hollow guide rod 521 from the upper end of the hollow guide rod 521, and then is pulled out by the pull-out component 530 through the lower end of the hollow guide rod 521. As the frame 100 moves forward, the spindle-shaped soil guide cover 522 can push the soil to both sides through its shape structure, and then guide the pushed soil to cover the original position again. This process also ensures the proper functioning of the soil entry component 520 and the pull-out component 530. The middle section of the drip irrigation tape is protected to prevent the soil from exerting additional pressure on this section of the drip irrigation tape. The drip irrigation tape, after being pulled by the traction component 530, will be fixed in the soil. Therefore, the entire process of laying the drip irrigation tape is not subject to external forces, but only to the tension of the traction component 530 as it pulls the drip irrigation tape out. Finally, the drip irrigation tape compaction mechanism 700 compacts the soil on the top side of the buried drip irrigation tape, further stabilizing the drip irrigation tape at the expected laying depth and laying line.

[0041] Beneficial effects: This application includes a first fertilization device 200 for first applying a first type of fertilizer (phosphate fertilizer or potassium fertilizer) that can inhibit the escape of nitrogen through ammonia gas.

[0042] In the first stage: the second type of fertilizer (ammonium nitrogen fertilizer) is extruded through the fertilizer extrusion auger 420. The second type of fertilizer (ammonium nitrogen fertilizer) is extruded into the ground in strips with a certain cross-sectional area. The strips with a certain cross-sectional area can reduce the contact area between the underground ammonium nitrogen fertilizer and the alkaline substances in the saline-alkali soil. This means that most of the ammonium nitrogen fertilizer inside will not come into contact with alkaline substances for a period of time, so that most of the nitrogen element of the ammonium nitrogen fertilizer will not be lost for a period of time. In addition, during the process of the ammonia gas produced by the ammonium nitrogen fertilizer that reacts with the alkaline substances on the surface and escapes from the soil gaps, the ammonia gas will react with the first type of fertilizer (such as phosphate fertilizer or potash fertilizer) mixed in the soil. Therefore, only a small amount of nitrogen element is lost in the form of ammonia gas in this stage.

[0043] Second stage: After a period of time, when the second type of fertilizer inside reacts with the alkaline substance, the drip irrigation tape, which is laid to a certain depth in the soil by the drip irrigation tape laying mechanism 500, infiltrates the soil and causes the released ammonia gas to dissolve in the water.

[0044] The corn tillage and sowing self-traction drip irrigation integrated machine of this application can deploy a water and fertilizer interaction system in one go. Through the above two stages, the nitrogen element of the second fertilizer is stabilized to the greatest extent in the alkaline soil. This achieves the effect of leaving the nitrogen element in the soil when a large amount of nitrogen element is lost in the form of ammonia gas during the application of nitrogen fertilizer in saline-alkali land.

[0045] As described above, the second fertilization component needs to apply a second type of fertilizer (ammonium nitrogen fertilizer or any type of nitrogen fertilizer) into the soil in a certain volume, so that the second type of fertilizer (ammonium nitrogen fertilizer or any type of nitrogen fertilizer) applied into the soil is distributed in strips with a certain cross-sectional volume in the soil, so that most of the second type of fertilizer inside will not react with the alkaline substances in the saline-alkali soil to produce ammonia gas within a certain period of time. In one possible embodiment, the hollow fertilizer application blade 430 includes a hollow lower fertilizer pipe 431, a soil dividing head 432, and a fertilizer guiding pipe 433. The hollow lower fertilizer pipe 431 is connected to the lower end of the second fertilizer box 410. The soil dividing head 432 is set at the front end of the hollow lower fertilizer pipe 431 and faces the walking direction of the frame 100. The fertilizer guiding pipe 433 is set on the soil dividing head 432, and one end is connected to the hollow lower fertilizer pipe 431, while the other end extends away from the walking direction of the frame 100.

[0046] In a specific implementation process, as the frame 100 moves, the soil separator 432 separates the loose soil. The fertilizer extrusion auger 420 then squeezes the second type of fertilizer from the second fertilizer box 410 into the hollow lower fertilizer pipe 431. The second type of fertilizer fills the hollow lower fertilizer pipe 431 and enters the fertilizer guide pipe 433 along it. As the frame 100 moves and the soil separator 432 separates the loose soil, the second type of fertilizer is squeezed out of the fertilizer guide pipe 433 in a cross-sectional shape and applied to the soil. The soil separated by the soil separator 432 falls back, fixing the second type of fertilizer in place, thus essentially fixing it in place. By maintaining the shape it was squeezed out, thus ensuring a certain cross-sectional volume, the following beneficial effects are achieved: For a period of time, the contact area between underground ammonium nitrogen fertilizer and alkaline substances in saline-alkali soil is reduced, preventing most of the internal ammonium nitrogen fertilizer from contacting alkaline substances for a period of time. This prevents the loss of most of the nitrogen element from the ammonium nitrogen fertilizer over a period of time. Furthermore, during the process of ammonia gas produced by the surface ammonium nitrogen fertilizer reacting with alkaline substances and escaping from soil gaps, the ammonia gas will react with the first fertilizer mixed in the soil (such as phosphate or potassium fertilizer), resulting in only a small amount of nitrogen being lost in the form of ammonia gas.

[0047] As described above, if the tape-pulling assembly does not have a driving mechanism to provide active pulling force, it is prone to jamming during actual use, preventing the drip irrigation tape from successfully entering the soil. This can lead to situations similar to the drip irrigation tape breakage during installation in existing technologies, or the drip irrigation tape reel jamming after being buried in the soil. Consequently, the drip irrigation tape is subjected to tensile force caused by the friction between the frame 100 and the soil, causing the tensile portion of the drip irrigation tape to break. In one possible embodiment, the tape-pulling assembly 530 includes a mounting rod 531, a mounting shell 532, a tape-pulling wheel assembly 533, and a driving component 534. The mounting rod 531 is mounted on the frame 100, and the mounting shell 532 is mounted on the mounting rod 531. At the lower end, the mounting shell 532 near the soil insertion component 520 has an inclined tape inlet 5321. The inclined tape inlet 5321 is an opening formed by two inclined surfaces that taper inward from the end into the mounting shell 532. When a new drip irrigation tape roller is installed, the drip irrigation tape itself has a certain rigidity, so the operator can insert the drip irrigation tape into the inclined tape inlet 5321. The two inclined surfaces can guide the drip irrigation tape to the correct position where it can be inserted into the opening of the puller assembly 533. The puller assembly 533 is rotatably disposed inside the mounting shell 532 and close to the inclined tape inlet 5321. The driving component 534 is disposed in the mounting shell 532 and is connected to the puller assembly 533 for transmission.

[0048] The belt traction assembly 530 includes a mounting rod 531, a mounting shell 532, a belt pulley assembly 533, and a driving component 534. The mounting rod 531 is vertically mounted on the frame 100. The mounting shell 532 is located at the lower end of the mounting rod 531 and is streamlined, which can guide the soil in front of the mounting rod 531 to the rear of the mounting rod 531. The belt pulley assembly 533 is rotatably mounted inside the mounting shell 532. The belt pulley assembly 533 can be a roller assembly with the function of conveying strip materials, or any structure that can convey bagged materials. The driving component 534 is located in the mounting shell 532 and is connected to the belt pulley assembly 533 for transmission, thereby driving the belt pulley assembly 533 to rotate.

[0049] The beneficial effects are as follows: the installation shell 532 can prevent soil from entering and pulling the drip irrigation tape, and the pull wheel assembly 533 actively squeezes and pulls the drip irrigation tape, so that the drip irrigation tape that enters the soil is not under tension, thus preventing the drip irrigation tape from breaking.

[0050] Furthermore, the traction assembly 530 also includes a positioning wheel set 535, which is disposed inside the mounting housing 532 and away from the inclined belt inlet 5321. The positioning wheel set 535 includes a first positioning wheel 5351 and a second positioning wheel 5352 rotatably disposed inside the mounting housing 532, and a positioning outlet 5353 is formed between the first positioning wheel 5351 and the second positioning wheel 5352.

[0051] Beneficial effect: The positioning outlet 5353 formed between the first positioning wheel 5351 and the second positioning wheel 5352 can guide the drip irrigation tape to a certain position, thereby facilitating the positioning of the drip irrigation tape laying depth.

[0052] Furthermore, the belt traction assembly 530 also includes a belt guide plate 536, which is disposed between the belt pulley assembly 533 and the positioning pulley assembly 535, and extends from the bottom of the mounting housing 532 to the positioning outlet 5353.

[0053] Beneficial effect: The guide plate 536 can guide the drip irrigation tape that has passed through a set of pull belt rollers 533 to the next set of pull belt rollers 533, preventing the drip irrigation tape from entering below the second positioning roller 5352 and entering the soil from a position other than the positioning outlet 5353.

[0054] In an actual working process, the conveying linear speed of the pulley assembly 533 is the same as the traveling linear speed of the frame 100. After the drip irrigation tape enters the soil, only the section of drip irrigation tape from the soil entry component 520 to the pulley assembly 533 is subjected to the tension of the soil. By simply controlling the distance between the soil entry component 520 and the pulley assembly 533 to be short, the section of drip irrigation tape can be prevented from being pulled apart.

[0055] Furthermore, the first fertilizer application mechanism 200 includes a first fertilizer box 210 and a plurality of fertilizer spreading troughs 220. The first fertilizer box 210 is disposed on the frame 100, and the plurality of fertilizer spreading troughs 220 are arranged at intervals and disposed at the lower end of the first fertilizer box 210.

[0056] The beneficial effects are as follows: multiple fertilizer spreading troughs 220 spread a large amount of the first type of fertilizer onto the soil surface, and then the rotary tillage mechanism 300 evenly mixes the first type of fertilizer into the soil. When the first type of fertilizer is distributed in the soil layer,

[0057] Furthermore, the second fertilization mechanism 400 includes a second fertilizer box 410 and a plurality of second fertilization components. The plurality of second fertilization components are arranged at intervals on the frame 100 perpendicular to the traveling direction of the frame 100 and are arranged corresponding to the plurality of fertilizer spreading troughs 220.

[0058] Furthermore, it also includes a sowing mechanism 600 disposed between the drip irrigation tape laying mechanism 500 and the drip irrigation tape compaction mechanism 700. The sowing mechanism 600 includes a first mounting frame 610 and a plurality of seed metering components 620. The first mounting frame 610 is disposed on the frame 100, and the plurality of seed metering components 620 are disposed on the first mounting frame 610 and are distributed at intervals along the direction perpendicular to the walking direction of the frame 100. The plurality of seed metering components 620 and the plurality of pull belt traction components 530 are staggered.

[0059] Furthermore, the seeding assembly 620 includes a seed box 621 and a duckbill seeder 622. The duckbill seeder 622 is rotatably mounted on the first mounting frame 610, and the seed box 621 is mounted on the duckbill seeder 622 and communicates with the duckbill seeder 622.

[0060] Beneficial effects: It aligns the sowing row with the fertilization row, ensuring that the seeds are sown on top of the fertilizer, allowing the corn seeds to better absorb nutrients and grow rapidly.

[0061] Furthermore, the pressing mechanism includes a second mounting frame 710 and a plurality of pressing wheels 720. One end of the second mounting frame 710 is disposed on the frame 100, and the pressing wheels 720 are rotatably disposed at the other end of the second mounting frame 710. The plurality of pressing wheels 720 are correspondingly disposed with the traction assembly 530.

[0062] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
