Description

Technical Field

[0001] The invention relates to the technical field of crop sowing, in particular to a wheat compound fertilizer and a cultivated land sowing and fertilizing integrated machine. Background Art

[0002] Wheat is the main grain crop in my country, and its sowing technology and management are crucial to ensure high yield and high quality of wheat. It is more appropriate to control the sowing depth of wheat at 3 to 5 cm. This depth range can ensure that the seeds fully absorb water and nutrients in the soil, improve the emergence rate, and lay the foundation for later growth and high yield. The application depth of chemical fertilizers also has an important impact on the growth of wheat. Generally speaking, deep application of wheat fertilizers can improve fertilizer efficiency. Base fertilizers are usually decomposed organic fertilizers or compound fertilizers. The application depth is generally deep, and can be applied to a soil layer of 15 to 20 cm. This allows the fertilizer to be fully mixed with the soil, improves soil fertility and air permeability, and provides a good soil environment for wheat growth.

[0003] In the existing wheat compound fertilizer and cultivated land sowing and fertilizing integrated machine, fertilization and sowing are mostly controlled separately through control components, and the fertilization and sowing depths are basically buried at the same depth. For example, the Chinese patent publication number CN214228853U discloses a sowing and fertilizing integrated machine. Although the depth of the plow can be adjusted, the depth of sowing and fertilization cannot be controlled at the same time, which may cause a large difference in depth between the applied fertilizer and the wheat seeds, affecting the seeds' full absorption of the fertilizer. If the depth difference between the applied fertilizer and the wheat seeds is small or they are mixed together, the seedlings may be burned. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figure 1-Figure 7 As shown, a wheat compound fertilizer and cultivated land sowing and fertilizing integrated machine of the present invention includes a material box 1 for storing fertilizers and seeds, wherein the middle of the material box 1 is divided into two storage spaces by a partition 11;

[0034] The bottom of the material box 1 is provided with a material leakage port, which is connected to both storage spaces; the bottom of the material box 1 is provided with an intermittent sowing box 12, and the bottom of the intermittent sowing box 12 is provided with a conduit 3 for guiding the fertilizer and seeds during leakage;

[0035] The conduit 3 is divided into two cavities in the middle, one of the cavities at the bottom of the conduit 3 is connected to a fertilizer pipe 32, and the other cavity at the bottom of the conduit 3 is connected to a seed pipe 33. Guide metal sheets 36 are arranged on both sides of the outer wall of the conduit 3;

[0036] The guide metal sheet 36 is used to prevent the sand from entering the planting ditch after fertilization.

[0037] At the same time, compound fertilizer and wheat seeds are put into the material box 1. When wheat is sown in sandy soil, the sandy soil is mainly composed of sand particles, which are rough and have a small specific surface area. There are many large pores between the particles, so it has the characteristics of good ventilation and water permeability and smooth drainage in the soil. The sowing depth is 4-6 cm, and the fertilizer depth is best at 10-15 cm. When wheat is planted, the cultivated land sowing and fertilizing integrated machine is installed on a tractor and connected to a power source. The tractor drives the material box 1 to move, and the wheat seeds and compound fertilizer can be leaked out at the same time through the conduit 3;

[0038] During the sowing process, the compound fertilizer is first leaked to the planting ditch 10-15 cm above the ground. After the compound fertilizer enters the planting ditch, part of the sandy soil can be covered on the upper surface of the compound fertilizer through the guide metal sheet 36. Then, during the movement, the wheat seeds are sprinkled into the planting ditch again to ensure that the wheat is at a depth of 4-6 cm from the inside, which is conducive to the growth of wheat.

[0039] When the guide metal sheet 36 is used to block the sand due to the granular properties of the sand, the sand can flow into the planting ditch along the guide metal sheet 36 to cover the compound fertilizer in time, and the setting of the guide metal sheet 36 can make the thickness of the sandy soil entering the planting ditch covering the compound fertilizer basically the same, thereby controlling the distance between the wheat seeds and the compound fertilizer within a preset range, which is beneficial to the absorption of fertilizer by the roots of the wheat after growth.

[0040] Specifically, the outer wall of the conduit 3 is fixedly connected to an outer fixed sleeve 31, and the guide metal sheet 36 is rotatably connected to the outer fixed sleeve 31. The guide metal sheet 36 is provided with an arc surface 361 on the side close to the fertilizer leakage pipe 32, wherein the thickness at a of the guide metal sheet 36 is greater than the thickness at b, and the thickness at b of the guide metal sheet 36 is greater than the thickness at c.

[0041] When the guide metal sheet 36 moves, it can block the soil placed on both sides of the planting trench during the opening of the planting trench. During the movement of the guide metal sheet 36, the sandy soil can move along the position a of the guide metal sheet 36 to the position c, and the sandy soil will be filled into the planting trench again, thereby achieving the coverage of the compound fertilizer by the sandy soil. The sandy soil is composed of sand particles and is arranged in conjunction with the guide metal sheet 36 to ensure the uniformity of the coverage of the compound fertilizer.

[0042] Specifically, the arc surface 361 of the guide metal sheet 36 is provided with guide corrugations, and the corrugations on the side a close to the guide metal sheet 36 are higher than the corrugations on the side c close to the guide metal sheet 36 .

[0043] During the movement of the guide metal sheet 36, the guide corrugations can guide the sandy soil, and can quickly move toward c of the guide metal sheet 36 during the soil pushing at a near the guide metal sheet 36, so that the sandy soil can be covered with compound fertilizer more smoothly and quickly.

[0044] Specifically, an end of the guide metal sheet 36 close to the outer fixing sleeve 31 is fixedly connected with an adjusting screw 34 . The adjusting screw 34 extends into the outer fixing sleeve 31 and is threadedly connected to the outer fixing sleeve 31 .

[0045] The adjusting screw 34 is clamped by the clamp and then rotated. The rotation of the adjusting screw 34 drives the guide metal sheet 36 to rotate, so that the angle of the guide metal sheet 36 can be adjusted, and the amount of sand and soil transferred into the planting ditch by the guide metal sheet 36 during sowing can be adjusted, so as to control the depth between the wheat seeds and the fertilizer, and ensure that the distance between the wheat seeds and the compound fertilizer after sowing is within a preset range.

[0046] Specifically, a crossbeam 2 is fixedly connected to one side of the material box 1, a front stabilizing frame 16 is fixedly arranged on the side of the crossbeam 2 away from the material box 1, and a plurality of furrowing plows 22 are welded to one side of the crossbeam 2, and the furrowing plows 22 are placed on the front side of the guide tube 3;

[0047] The conduit 3 is fixed to the side wall of the crossbeam 2 , and the top of the conduit 3 is connected to the material box 1 through the intermittent sowing box 12 .

[0048] The crossbeam 2 serves as a connecting support, wherein the front stabilizer frame 16 can play a supporting role when driving the material box 1 to move, and the furrowing plow 22 can be used to open planting furrows. The guide tube 3 is placed on the rear side of the furrowing plow 22 to timely transport fertilizers and seeds to the preset position.

[0049] Specifically, support frames 21 are provided on both sides of the beam 2, a driver 4 is fixedly connected to the middle of the beam 2 close to the material box 1, active output shafts 41 are connected to both sides of the driver 4, and the active output shaft 41 is rotatably connected to the support frame 21 at one end away from the driver 4.

[0050] A sowing control rod 13 for controlling the seed leakage speed is arranged in the middle of the plurality of intermittent sowing boxes 12 . A transmission box 14 is arranged between the sowing control rod 13 and the end of the active output shaft 41 . The transmission box 14 is fixedly connected to the support frame 21 .

[0051] During the sowing process, the driver 4 is connected to the tractor power source to drive the driver 4 to rotate. During the operation, the driver 4 drives the active output shafts 41 arranged on both sides to rotate. During the rotation of the active output shaft 41, one end drives the sowing control rod 13 to rotate through the transmission box 14. During the rotation, the sowing control rod 13 can cooperate with the intermittent sowing box 12 to control the wheat seeds and compound fertilizer to fall slowly and continuously from the material box 1.

[0052] Specifically, one side of the cross beam 2 is connected to a plurality of soil covering components 6 via a fixing plate. The soil covering components 6 are fixedly arranged in the middle of the fixing plate. The soil covering components 6 include a mounting cover 61 , wherein the active output shaft 41 rotates and penetrates the mounting cover 61 .

[0053] By setting up multiple sets of soil covering components 6, the sandy soil can be covered in the planting ditch again to cover the seeds, thereby preventing the seeds from being exposed to the sun and losing water, which would affect the growth of the wheat seeds.

[0054] Specifically, a rotating shaft 62 is provided through the middle of one end of the mounting cover 61 away from the active output shaft 41, the active output shaft 41 is transmission-connected to the rotating shaft 62, the rotating shaft 62 extends to a position outside the mounting cover 61 and is fixedly connected to a connecting plate 63, and a soil-moving piece 66 is fixedly connected to the side wall of the connecting plate 63 by bolts.

[0055] The active output shaft 41 drives the transmission part through the mounting cover 61 to drive the rotating shaft 62 to rotate synchronously. During the rotation process, the rotating shaft 62 drives the externally connected connecting disk 63 to rotate. During the rotation process, the connecting disk 63 drives the soil-moving piece 66 to rotate. When the soil-moving piece 66 rotates, it can turn over the sandy soil and cover the sand in the planting furrows on the wheat planting again, which is beneficial to the growth of wheat seeds.

[0056] Specifically, a bulldozer elastic sheet 64 is fixedly connected to one end of the mounting cover 61 away from the active output shaft 41 , and a baffle 641 is fixedly connected to one side of the bulldozer elastic sheet 64 close to the seed leakage pipe 33 .

[0057] When the mounting cover 61 moves, the bulldozer elastic sheet 64 can push the soil to cover the surface of the wheat seeds. After the wheat seeds fall into the planting ditch through the seed leakage tube 33, they will hit the baffle 641 and then rebound into the ditch. The baffle 641 is made of soft material to prevent the seeds from falling too fast and being more dispersed in the planting ditch.

[0058] A wheat compound fertilizer, comprising the main elements of nitrogen, phosphorus and potassium, wherein the ratio of nitrogen, phosphorus and potassium is 15:15:15.

[0059] The compound fertilizer also includes trace elements of boron, manganese, zinc, copper and molybdenum. The proportions of trace elements are: 0.02% boron, 0.1% manganese, 0.05% zinc, 0.01% copper and 0.01% molybdenum.

[0060] The nitrogen, phosphorus and potassium ratios in sandy soils vary depending on their geographical location, climate conditions, soil management and other factors. However, according to multiple professional studies and actual measurement results, the total nitrogen content of sandy soils is usually between 0.04% and 0.16%, and some studies have shown that the total nitrogen content standard is generally above 0.08%. Nitrogen content within this range plays a key role in the growth and development of crops such as wheat;

[0061] The total phosphorus content of sandy soil is usually between 0.01% and 0.04%. The available phosphorus content is an important indicator to measure the effectiveness of phosphorus in the soil. For sandy soil, the available phosphorus content standard is generally above 8 mg / kg. Phosphorus is a component of plant cell membranes and an important element for photosynthesis and energy metabolism in plants.

[0062] The total potassium content of sandy soil is usually between 0.10% and 0.30%. Available potassium refers to the potassium in the soil that is easily absorbed and utilized by plants. For sandy soil, the available potassium content is generally above 80 mg / kg. Potassium plays an important role in maintaining cell osmotic pressure, promoting photosynthesis and material transport in plants.

[0063] Working principle: First, the fertilizer spreader is installed on the tractor. During the sowing process, the driver 4 is connected to the tractor power source to drive the driver 4 to rotate. During the operation, the driver 4 drives the active output shafts 41 arranged on both sides to rotate. During the rotation of the active output shaft 41, one end drives the sowing control rod 13 to rotate through the transmission box 14. During the rotation, the sowing control rod 13 can cooperate with the intermittent sowing box 12 to control the wheat seeds and compound fertilizer to fall slowly and continuously from the material box 1.

[0064] Compound fertilizer and wheat seeds are placed in the material box 1. When wheat is sown in sandy soil, the sandy soil is mainly composed of sand particles, which are rough and have a small specific surface area. There are many large pores between the particles, so it has the characteristics of good ventilation and water permeability and smooth drainage in the soil. The sowing depth is 4-6 cm, and the fertilizer depth is best at 10-15 cm. When wheat is planted, the cultivated land sowing and fertilizing integrated machine is installed on a tractor and connected to a power source. The tractor drives the material box 1 to move, and the wheat seeds and compound fertilizer can be leaked out at the same time through the conduit 3;

[0065] During the sowing process, the compound fertilizer is first leaked to the planting ditch 10-15 cm above the ground. After the compound fertilizer enters the planting ditch, part of the sandy soil can be covered on the upper surface of the compound fertilizer through the guide metal sheet 36. Then, during the movement, the wheat seeds are sprinkled into the planting ditch again to ensure that the wheat is at a depth of 4-6 cm from the inside, which is conducive to the growth of wheat.

[0066] When the guide metal sheet 36 is used to block the sand due to the granular properties of the sand, the sand can flow into the planting ditch along the guide metal sheet 36 to cover the compound fertilizer in time, and the setting of the guide metal sheet 36 can make the thickness of the sandy soil entering the planting ditch covering the compound fertilizer basically the same, thereby controlling the distance between the wheat seeds and the compound fertilizer within a preset range, which is beneficial to the absorption of fertilizer by the roots of the wheat after growth.

[0067] When the guide metal sheet 36 moves, it can block the soil placed on both sides of the planting ditch during the process of opening the planting ditch. During the movement of the guide metal sheet 36, the sandy soil can move along the position a of the guide metal sheet 36 to the position c, and the sandy soil will be filled into the planting ditch again, thereby achieving the covering of the compound fertilizer by the sandy soil. The sandy soil is composed of sand particles and is arranged in conjunction with the guide metal sheet 36 to ensure the uniformity of the coverage of the compound fertilizer. During the movement of the guide metal sheet 36, the guide corrugations can guide the sandy soil, and can quickly move to the position c of the guide metal sheet 36 during the process of pushing the soil at the position a near the guide metal sheet 36, so that the sandy soil can cover the compound fertilizer more smoothly and quickly.

[0068] The active output shaft 41 drives the transmission part through the mounting cover 61 to drive the rotating shaft 62 to rotate synchronously. During the rotation process, the rotating shaft 62 drives the externally connected connecting disk 63 to rotate. During the rotation process, the connecting disk 63 drives the soil-moving piece 66 to rotate. When the soil-moving piece 66 rotates, it can turn over the sandy soil and cover the sand in the planting furrows on the wheat planting again, which is beneficial to the growth of wheat seeds.
