Description

Technical Field

[0001] The present application relates to the technical field of drip irrigation fertilization equipment, and in particular to a fertilization equipment for wheat field management and a fertilization method thereof. Background Art

[0002] As an important food crop and cash crop, wheat has a yield and planting area second only to rice, and plays an important role in people's livelihood and economy. In the process of wheat planting, fertilization is an indispensable measure. Among them, the nitrogen fertilizer postponement technology is often used for wheat fertilization. Base fertilizer is applied in autumn, and nitrogen fertilizer is applied later. The time is postponed from the early growth stage of wheat to the jointing stage or the flag leaf tip stage, thereby effectively improving the fertilization effect on wheat.

[0003] In addition, fertilizer technology is developing towards high-concentration, compound, liquid and slow-release water-soluble fertilizers. Combined with drip irrigation technology, it can directly supply water, fertilizer or other chemical agents to the soil, so that the soil in the root zone of wheat can be kept in the best condition. This is the main development trend of irrigation and fertilization in the process of wheat planting.

[0004] The drip irrigation and fertilization of wheat mainly adopts the drip irrigation tape, which is laid in the field for drip irrigation and fertilization during the wheat growth period, and is taken back during the harvest period to facilitate the harvesting of wheat by harvester and the subsequent tillage operation;

[0005] However, during the operation of the existing drip irrigation belt, the water pressure of the drip irrigation holes thereon varies greatly due to the influence of the terrain and the distance. The water pressure of the drip irrigation holes located at a lower terrain or closer to the pump group is higher, and the water output of the drip irrigation holes at their section positions is more. The water pressure of the drip irrigation holes located at a higher terrain or farther from the pump group is lower, and the water output of the drip irrigation holes at their section positions is less. As a result, the uniformity of the drip irrigation belt is poor when performing drip irrigation and fertilization operations over a large area, which seriously affects the consistency of wheat crop growth, and the stability and reliability are poor. Summary of the invention

[0006] The present application proposes a fertilization equipment and a fertilization method for wheat field management, which can effectively regulate the water outlet pressure of each section of the drip irrigation holes on the drip irrigation belt, ensure the synchronization of its drip irrigation and fertilization, and make the water outlet of the drip irrigation holes on it not easily affected by the height of the terrain or the distance, and have the advantage of better uniformity when performing large-scale drip irrigation and fertilization operations. It is used to solve the problem that during the operation of the existing drip irrigation belt, the water pressure of the drip irrigation holes on it is greatly different due to the influence of the terrain and the distance. The water pressure of the drip irrigation holes located at a lower terrain or closer to the pump group is larger, and the water outlet of the drip irrigation holes at the section position is larger, while the water pressure of the drip irrigation holes located at a higher terrain or farther from the pump group is smaller, and the water outlet of the drip irrigation holes at the section position is smaller, which leads to the problem of poor uniformity of the drip irrigation belt when performing large-scale drip irrigation and fertilization operations.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a fertilization equipment for wheat field management, comprising a drip irrigation belt, wherein the inner cavity of the drip irrigation belt and the folds on both sides thereof are respectively provided with a plurality of connecting rods and hollow rods, one end of the connecting rod is fixedly installed on the left side of the fold of the inner cavity of the drip irrigation belt, and the other end of the connecting rod is fixedly installed with an adjusting rod, a groove is provided on the right side of the outer surface of the connecting rod, and the groove is connected with the spiral groove provided on the left side of the outer surface of the adjusting rod, and a straight groove extending to the right end face of the adjusting rod is provided on the right side of the outer surface of the adjusting rod; one end of the hollow rod is fixedly installed on the right side of the fold of the inner cavity of the drip irrigation belt and extends to the outside of the drip irrigation belt to form a drip irrigation hole, and one end of the adjusting rod extends into the inner cavity of the hollow rod, and an inner annular groove is provided in the middle of the inner cavity of the hollow rod.

[0008] Furthermore, spring sheets are provided on the outer surface of the drip irrigation belt and at the upper and lower ends of the fold on one side of the connecting rod, and the elastic force of the spring sheets is directed toward the inner side of the drip irrigation belt.

[0009] Furthermore, the inner wall of the drip irrigation tape is provided with an annular groove corresponding to the position of the adjusting rod, thereby providing a accommodating space for the connecting rod, the adjusting rod and the hollow rod when the drip irrigation tape is rolled up.

[0010] Furthermore, a connecting hole is provided inside the adjusting rod, one end of the connecting hole extends to the middle of the outer surface thereof, and the other end of the connecting hole extends to the right end surface thereof.

[0011] Furthermore, the connecting hole extends to the end of the outer surface of the adjusting rod and is flush with the end of the hollow rod when the drip irrigation tape is fully rolled up.

[0012] Furthermore, an elastic diaphragm is fixedly installed on the left side of the inner cavity of the hollow rod and is in frictional contact with the outer surface of the adjusting rod.

[0013] A fertilization method of a fertilization device for wheat field management, comprising the following operating steps:

[0014] S1. Connect the end of the drip irrigation belt to the pump group, and arrange the drip irrigation belt in the field where drip irrigation and fertilization are required. At the same time, the prepared water-fertilizer solution is squeezed into the inner cavity of the drip irrigation belt by the pump group, and transported to the field through the drip irrigation belt;

[0015] S2. In the initial state, the drip irrigation belt is kept flat under the elastic force of the spring sheet, and is gradually stretched out when conveying the water and fertilizer solution. At the same time, as the drip irrigation belt is stretched out, the connecting rod and the hollow rod on it are close to each other;

[0016] S3. When the entire section of the drip irrigation belt is fully stretched into a circular structure, the spiral groove and the straight groove on the adjusting rod are interconnected under the action of the inner ring groove, so that the water and fertilizer solution flowing on the drip irrigation belt is discharged through the groove, the spiral groove, the inner ring groove and the straight groove, so as to synchronously trigger all the hollow rods to perform drip irrigation and fertilization operations on wheat;

[0017] S4. After the drip irrigation and fertilization operation is completed, as the pump group is turned off, the water pressure in the inner cavity of the drip irrigation belt decreases, and under the action of the spring, the drip irrigation belt is squeezed into an elliptical structure again, causing the distance between the connecting rod and the hollow rod to become farther, and the spiral groove moves away from the inner ring groove again to cut off the channel therebetween, and all the drip irrigation holes on the drip irrigation belt are disconnected synchronously.

[0018] The present invention application has the following technical effects:

[0019] The present application provides a fertilization device for wheat field management and a fertilization method thereof. Through the fertilization device for wheat field management and the fertilization method thereof, for the arrangement of the connecting rod, the adjusting rod and the structure thereon on the drip irrigation belt, the shape change of the drip irrigation belt when it is filled with water-fertilizer solution can be utilized to control the triggering state of the drip irrigation holes thereon, and all the drip irrigation holes can be synchronously triggered when the drip irrigation belt is completely filled and squeezed into a circular structure, thereby making the water output of the drip irrigation holes thereon less susceptible to the influence of the height of the terrain or the distance, thereby effectively ensuring the synchronization and uniformity of the drip irrigation and fertilization of wheat over a large area.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] like Figure 1-Figure 3 As shown, a fertilization equipment for wheat field management includes a drip irrigation belt 1 laid in the wheat field, one end of the drip irrigation belt 1 is connected to a pump group, and water and water-soluble fertilizers are transported to the field through the drip irrigation belt 1 through the pump group, and the inner cavity of the drip irrigation belt 1 and the folds on both sides thereof are respectively provided with a plurality of groups of equally spaced connecting rods 2 and hollow rods 8, one end of the connecting rod 2 is fixedly mounted on the left side of the fold of the inner cavity of the drip irrigation belt 1, and the other end of the connecting rod 2 is fixedly mounted with an adjusting rod 3, and the right side of the outer surface of the connecting rod 2 is provided with three groups of grooves 4 arranged in a circular array, and the groove 4 is connected with a spiral groove 5 opened on the left side of the outer surface of the adjusting rod 3, wherein, for the setting of the spiral groove 5, in order to reduce the impact pressure of the water flow so that it can flow out in a relatively gentle manner and perform drip irrigation and fertilization operations, the right side of the outer surface of the adjusting rod 3 is provided with three groups of straight grooves 6 arranged in a circular array and extending to the right end face thereof;

[0030] like Figure 4-Figure 5 As shown, one end of the hollow rod 8 is fixedly installed on the right side of the fold of the inner cavity of the drip irrigation belt 1 and extends to the outside of the drip irrigation belt 1 to form a drip irrigation hole, and one end of the adjustment rod 3 extends into the inner cavity of the hollow rod 8, and an inner ring groove 9 is opened in the middle of the inner cavity of the hollow rod 8;

[0031] When the pump group operates to squeeze and transport water to the inner cavity of the drip irrigation belt 1, when the inner cavity of the drip irrigation belt 1 is filled with water and expanded into a circle, the connecting rod 2 and the hollow rod 8 in the inner cavity of the drip irrigation belt 1 approach each other, and are connected to the spiral groove 5 and the straight groove 6 on the adjusting rod 3 through the inner annular groove 9, so that the water and fertilizer in the inner cavity of the drip irrigation belt 1 are discharged through the groove 4, the spiral groove 5, the inner annular groove 9 and the straight groove 6.

[0032] like Figure 1 As shown, in the present technical solution, spring pieces 12 are provided on the outer surface of the drip irrigation belt 1 and at the upper and lower ends of the fold on one side of the connecting rod 2, and the elastic force of the spring pieces 12 is directed toward the inner side of the drip irrigation belt 1;

[0033] Furthermore, when the inner cavity of the drip irrigation belt 1 is not subjected to force, the drip irrigation belt 1 is kept in an elliptical shape, so that the spiral groove 5 on the adjusting rod 3 is completely retracted into the inner cavity of the drip irrigation belt 1, thereby preventing the drip irrigation belt from being blocked due to cold and ice formation;

[0034] When the pump group is triggered and water is squeezed and transported through the drip irrigation belt 1, the pressure point at which the drip irrigation belt 1 is stretched into a circular structure is controlled by the spring piece 12, and the water in the drip irrigation belt 1 can flow forward until its front and rear positions are all stretched into a circular structure, so as to synchronously trigger all the hollow rods 8 on the drip irrigation belt 1 to perform drip irrigation and fertilization operations.

[0035] In the present technical solution, the inner wall of the drip irrigation tape 1 is provided with an annular groove 11 corresponding to the position of the adjusting rod 3, so that when the drip irrigation tape 1 is rolled up, a accommodating space can be provided for the connecting rod 2, the adjusting rod 3 and the hollow rod 8, thereby preventing the rolled-up drip irrigation tape 1 from causing excessive squeezing of the connecting rod 2, the adjusting rod 3 and the hollow rod 8. At the same time, the stability and reliability of the structure of the rolled-up drip irrigation tape 1 are effectively improved, and the loosening phenomenon during transportation is avoided.

[0036] like Figure 2 As shown, in the present technical solution, a connecting hole 7 is provided inside the adjusting rod 3, one end of the connecting hole 7 extends to the middle of its outer surface, and the other end of the connecting hole 7 extends to its right end surface, so that during the process of winding and compressing the drip irrigation tape 1, the residual water-fertilizer solution therein can be discharged through the connecting hole 7 to prevent the drip irrigation tape 1 from being damaged due to freezing and expansion due to cold.

[0037] In the present technical solution, the connecting hole 7 extends to the end of the outer surface of the adjusting rod 3 and is flush with the end of the hollow rod 8 when the drip irrigation tape 1 is fully rolled up. Then, when the drip irrigation tape 1 is deformed due to the internal squeezing of the transported water, the connection between the connecting hole 7 and the inner cavity of the drip irrigation tape 1 can be cut off in time to effectively prevent the water-fertilizer solution of the drip irrigation tape 1 from leaking out through the connecting hole 7 during the transportation process.

[0038] In the present technical solution, an elastic diaphragm 10 is fixedly installed on the left side of the inner cavity of the hollow rod 8 and is in frictional contact with the outer surface of the adjusting rod 3 .

[0039] A fertilization method of a fertilization device for wheat field management, comprising the following operating steps:

[0040] S1, connect the end of the drip irrigation belt 1 with the pump group, and arrange the drip irrigation belt 1 in the field where drip irrigation and fertilization are required. At the same time, the prepared water-fertilizer solution is squeezed into the inner cavity of the drip irrigation belt 1 by the pump group, and transported to the field through the drip irrigation belt 1;

[0041] S2. In the initial state, under the elastic force of the spring sheet 12, the drip irrigation belt 1 is kept flat, and is gradually expanded when the water fertilizer solution is transported. At the same time, as the drip irrigation belt 1 is expanded, the connecting rod 2 and the hollow rod 8 thereon are brought closer to each other;

[0042] S3. When the entire section of the drip irrigation belt 1 is fully expanded into a circular structure, the spiral groove 5 and the straight groove 6 on the adjusting rod 3 are connected to each other under the action of the inner ring groove 9, so that the water and fertilizer solution flowing on the drip irrigation belt 1 is discharged through the groove 4, the spiral groove 5, the inner ring groove 9 and the straight groove 6, so as to synchronously trigger all the hollow rods 8 to perform drip irrigation and fertilization operations on wheat;

[0043] S4. After the drip irrigation and fertilization operation is completed, as the pump group is turned off, the water pressure in the inner cavity of the drip irrigation belt 1 decreases, and then under the action of the spring 12, the drip irrigation belt 1 is squeezed into an elliptical structure again, causing the distance between the connecting rod 2 and the hollow rod 8 to become farther, and the spiral groove 5 moves away from the inner ring groove 9 again to cut off the passage therebetween, and all the drip irrigation holes on the drip irrigation belt 1 are disconnected synchronously.
