Description

Technical Field

[0002] Wheat is a crop with strong adaptability. It has relatively low requirements for climate and soil, and wheat has good drought resistance. It is often used as the main crop in sandy land areas. During the planting and growth process of wheat, it is necessary to pay attention to the timely addition of fertilizers. The general principle of fertilization is to increase the application of compound microbial fertilizers and organic fertilizers, and properly control the application of chemical fertilizers. Compound microbial fertilizers organically combine inorganic nutrients, organic matter, and microbial bacteria, reflecting the comprehensive effects of inorganic chemical fertilizers, organic fertilizers, and microbial fertilizers. It can resolve soil compaction, repair and condition the soil, improve the utilization rate of chemical fertilizers, reduce river pollution, and reduce the occurrence of diseases and pests. It can also enhance the stress resistance of wheat after planting. It is the preferred fertilizer for improving crop quality and yield.

[0003] However, after fertilizing sandy land, due to the loose soil, good ventilation and warm soil, the fertilizer will decompose in a short time, and the fertilizer effect will be strong but short-lived without any stamina, resulting in an increase in the number of fertilizations, which increases the consumption of manpower and material resources. Frequent fertilization operations will also affect the normal growth of crops. In addition, wheat seeds are scattered over a large area in the planting area.

[0030] 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.

[0031] The embodiment of the present invention provides a wheat biofilm composite fertilizer fertilizing device, which solves the problem that the existing fertilizing device is difficult to change the combination mode between fertilizer and soil after fertilization according to the soil properties, and is difficult to control the fertilization distance between the fertilizer and the wheat seedlings, thereby increasing the probability of "seedling burning" or rapid nutrient loss.

[0032] To improve fertilization efficiency, Figures 1 to 4As shown, a preferred embodiment of the present invention proposes a wheat biofilm composite fertilizer fertilizing device, including a fertilizer frame 1 and a compost bin 2, wherein the fertilizer frame 1 is fixedly provided with a traction assembly combined with an agricultural locomotive, and both ends of the fertilizer frame 1 are provided with walking wheels, and the compost bin 2 is fixedly installed above the fertilizer frame 1, and a plurality of fertilizer pipes 3 are movably installed in the middle and lower part of the fertilizer frame 1, and the fertilizer distribution pipe 3 is located below the compost bin 2. In addition, it also includes a ground frame 4 and a fertilizer transport frame 6, wherein the ground frame 4 is horizontally installed in the middle position of the fertilizer frame 1, and a plurality of ground frames 4 are provided, and the ground frames 4 correspond to the fertilizer distribution pipe 3 one by one, and a gravity hammer 5 is movably installed at one end of the ground frame 4 close to the fertilizer distribution pipe 3, and a leveling rod 40 is fixedly installed in the middle of the ground frame 4 in an "eight" shape.

[0033] During operation, a predetermined volume of biofilm compound fertilizer is first filled into the compost bin 2, and then the fertilizer rack 1 is connected and fixed to the existing agricultural locomotive, and the fertilizer rack 1 is towed by the agricultural locomotive to move in the field. At this time, the walking wheels on both sides of the fertilizer rack 1 move in the field gullies, and the multiple fertilizer distribution pipes 3 that are movably arranged can be adjusted in number and position according to the number of wheat planting holes or the fertilization spacing. During the movement of the fertilizer rack 1, the fertilizer distribution pipes 3 are always located above the field soil. In the early stage of wheat planting, the weeds or dead branches on the fertilization path can be pushed to both sides by the leveling rod 40 moving close to the ground, thereby increasing the contact degree between the fertilizer and the soil after fertilization.

[0034] Furthermore, in order to reduce the rapid loss of fertilizer effect caused by loose sandy soil, Figures 1 to 4 ,as well as Figure 6 As shown, the fertilizer transport frame 6 is hingedly installed on the upper part of the fertilizer frame 1, and a tension spring is connected between the hinged part of the fertilizer transport frame 6 and the fertilizer frame 1. The fertilizer transport frame 6 extends downward in an inclined state to the inner side of the ground frame 4, and the fertilizer transport frame 6 and the ground frame 4 maintain an inclined angle in the range of 30 to 60 degrees, and the middle part of the ground frame 4 is provided with a waist-shaped groove coupled with the end of the fertilizer transport frame 6, the fertilizer distribution pipe 3 is slidably installed in the middle and lower position of the fertilizer transport frame 6, and the axis of the fertilizer distribution pipe 3 is consistent with the inclination direction of the fertilizer transport frame 6, a hydraulic push rod 61 is fixedly installed on the upper part of the fertilizer transport frame 6, and the telescopic end of the hydraulic push rod 61 is fixedly connected to the upper end of the inclined position of the fertilizer distribution pipe 3, and a mud removal spring 60 is provided at the lower part of the fertilizer transport frame 6 to fit the outer wall of the fertilizer distribution pipe 3.

[0035] During operation, the inclination angle of the fertilizer transport frame 6 is adjusted according to the growth of wheat, and then the inclination angle of the fertilizer distribution pipe 3 is adjusted. Under the pushing action of the telescopic end of the hydraulic push rod 61, the fertilizer distribution pipe 3 extends in its inclination direction and is inserted into the soil at the wheat planting position. By adjusting its inclination angle, the depth of the fertilizer distribution pipe 3 inserted into the soil can be adjusted to meet the nutrient absorption needs of the root system during different stages of wheat growth. After the fertilizer distribution pipe 3 is inserted into the soil, the pre-loaded predetermined amount of biofilm compound fertilizer is released and buried in the soil, realizing fixed-point and quantitative fertilization. At the same time, the exposure of fertilizer to the air or environment is reduced, thereby reducing its decomposition or loss rate and improving the duration of fertilizer effectiveness. When fertilization is completed, the telescopic end of the hydraulic push rod 61 is reset and the fertilizer distribution pipe 3 is pulled upward to move it out of the soil for fertilization at the next position. In the process of pulling the fertilizer distribution pipe 3 out of the soil, the mud removal spring 60 slides against the outer wall of the fertilizer distribution pipe 3 and uses its own elastic expansion and contraction ability to achieve self-cleaning of the outer wall of the fertilizer distribution pipe 3 and itself, thereby improving the continuous working time of the fertilization device and reducing the frequency of cleaning and maintenance operations.

[0036] Furthermore, in order to adapt to the growth stage of wheat and carry out quantitative fertilization, e.g. Figures 4 to 7 ,as well as Fig. 9 As shown, a fertilizer compartment 62 is fixedly installed in the middle of the fertilizer transport frame 6, and the upper part of the fertilizer compartment 62 is connected to the compost bin 2 through a plurality of pipelines. The middle and lower part of the inner side of the fertilizer distribution pipe 3 is a cavity structure, and the middle and upper part of the fertilizer distribution pipe 3 is provided with a fertilizer distribution channel 31 connected to the lower cavity thereof. A fertilizer taking pipe 32 is fixedly installed on the upper part of the fertilizer distribution pipe 3, and the lower end of the fertilizer taking pipe 32 is connected to the fertilizer distribution channel 31, and the upper end of the fertilizer taking pipe 32 slides through the bottom of the fertilizer compartment 62, and the fertilizer distribution pipe 32 is connected to the compost bin 2 through the upper end of the fertilizer taking pipe 32. A through hole 63 is provided at the bottom of the fertilizer bin 62, and the outer wall of the fertilizer pipe 32 is slidably matched with the inner wall of the through hole 63. A fertilizer retaining strip 64 made of elastic material is fixedly installed at the inner bottom of the fertilizer bin 62. A long groove 33 connected to the inner cavity of the fertilizer bin 62 is provided at the middle side wall of the fertilizer pipe 3. A polarizing plate 65 is fixedly installed at the bottom of the fertilizer bin 62, and a concave groove 66 matching the end of the polarizing plate 65 is provided at intervals on the outer wall of the telescopic end of the hydraulic push rod 61.

[0037] During operation, in the fertilization stage, the fertilizer in the compost bin 2 is dispersed and falls into the fertilizer bin 62 through the pipeline under the action of gravity. The fertilizer retaining strip 64 arranged at the bottom of the fertilizer bin 62 can be used to prevent the fertilizer from falling at the penetration hole 63. At the same time, the fertilizer retaining strip 64 can provide a buffer for the fertilizer accumulated at the bottom of the fertilizer bin 62 by utilizing its own elastic deformation and giving way ability, so as to avoid the decomposition and crushing of the bottom fertilizer due to excessive squeezing, thereby ensuring the integrity of the fertilizer before and after fertilization, thereby improving the uniformity of its fertilizer release. After a single fertilization is completed, the hydraulic push rod 61 drives the fertilizer distributing pipe 3 to move upward and reset, and the fertilizer distributing is completed. The tube 3 drives the fertilizer taking tube 32 to move upward synchronously. When the fertilizer taking tube 32 moves upward to a predetermined height position, its end penetrates along the penetration hole 63. After passing through the fertilizer blocking strip 64, the fertilizer taking tube 32 enters the fertilizer filled inside the fertilizer compartment 62. With the further movement of the fertilizer taking tube 32, the long groove 33 enters the fertilizer compartment 62. Subsequently, the fertilizer in the fertilizer compartment 62 falls into the long groove 33 by gravity, and reaches the fertilizer distribution channel 31 through the fertilizer taking tube 32. By adjusting the length or inner diameter of the fertilizer distribution channel 31, the amount of fertilizer entering during the fertilization process can be accurately adjusted. At the same time, in order to accelerate the falling rate of the fertilizer and improve the fertilization efficiency, in the process of the telescopic end of the hydraulic push rod 61 contracting and driving the fertilizer distribution pipe 3 to move upward, the concave grooves 66 arranged on the telescopic end of the hydraulic push rod 61 slide through the end of the polarizing plate 65 one by one, thereby causing the polarizing plate 65 to produce reciprocating deflection, causing the fertilizer distribution bin 62 and the fertilizer inside it to vibrate, thereby accelerating the flow and filling rate of the fertilizer into the fertilizer collection pipe 32, thereby improving the fertilization efficiency during continuous fertilization operations, and at the same time achieving precise control of the amount of fertilizer applied, avoiding the problem of "burning seedlings" or weak fertility caused by uneven single fertilization.

[0038] Furthermore, in order to achieve accurate filling of fertilizer into the soil during fertilization, Figures 6 to 9 As shown, the lower end of the fertilizer distribution pipe 3 in the inclined direction is a pointed cone structure, a lower fertilizer groove 34 is provided on the side of the lower cavity of the fertilizer distribution pipe 3 facing the soil direction, and a fertilizer blocking rod 35 made of tough material is evenly inserted and installed on the inner side of the notch of the lower fertilizer groove 34, a fertilizer pushing column 36 is slidably installed in the middle and lower cavity of the fertilizer distribution pipe 3, a fertilizer pushing cylinder 37 is fixedly installed in the fertilizer distribution pipe 3, and the telescopic end of the fertilizer pushing cylinder 37 is fixedly connected to the fertilizer pushing column 36, a crescent groove 361 connected to the fertilizer distribution flow channel 31 is provided on one side of the fertilizer pushing column 36, a meniscus 351 protruding toward the axial direction of the fertilizer pushing column 36 is fixedly installed on the side wall of the fertilizer blocking rod 35, an anti-blocking column 38 is slidably installed on the inner side of the tapered end of the fertilizer distribution pipe 3, a compression spring 381 is connected between the anti-blocking column 38 and the fertilizer distribution pipe 3, and the side of the anti-blocking column 38 facing the fertilizer pushing column 36 is an inclined surface structure.

[0039] During operation, when the fertilizer distribution pipe 3 is at the upper station and the fertilizer replenishment operation is completed, after the fertilizing frame 1 moves forward to the next fertilizing station, the hydraulic push rod 61 is started again to work, so that the fertilizer distribution pipe 3 is inserted obliquely into the inner side of the soil again. When the fertilizer taking pipe 32 is pulled out of the penetration hole 63, the fertilizer blocking bar 64 can reset itself and block the penetration hole 63. In the process of the fertilizer distribution pipe 3 being obliquely inserted into the soil, the fertilizer blocking rods 35 arranged in strips can achieve isolation between the soil and the fertilizer. The telescopic end of the fertilizer pushing cylinder 37 is in a contracted state, and the crescent groove 361 on the fertilizer pushing column 36 is engaged with the fertilizer distribution channel 31. The fertilizer flowing into the fertilizer distribution channel 31 continues to flow downward to the cavity area where the fertilizer blocking rod 35 is located by gravity. After the fertilizer distribution pipe 3 is obliquely inserted into the soil, the fertilizer pushing cylinder 37 is started to work, and the fertilizer pushing column 36 is pushed to move in the direction close to the anti-blocking column 38 through its telescopic end, and the fertilizer is pushed further downward by the fertilizer pushing column 36 to improve its aggregation degree.

[0040] When the end of the fertilizer pushing column 36 moves to the position of the meniscus 351, the meniscus 351 is deflected by the pushing effect of the end of the fertilizer pushing column 36, thereby causing the fertilizer blocking rod 35 to expand and deflect in the direction away from the axis of the fertilizer distribution pipe 3, thereby opening the lower fertilizer trough 34 area. At this time, the fertilizer in the fertilizer distribution pipe 3 immediately slides downward and contacts the soil. The elastically arranged anti-blocking column 38 can provide a guiding effect for the outflow path of the fertilizer, and at the same time provide a buffer area for the discharge process of the fertilizer, thereby preventing the fertilizer from being squeezed and crushed due to uneven force during the fertilization process. When the fertilizer blocking rod 35 is in the tilted open state, the hydraulic push rod 61 is started again to work, and the hydraulic The telescopic end of the push rod 61 pulls the fertilizer distribution tube 3 to move upward, so that it is pulled out of the soil layer again. At this time, the fertilizer in the fertilizer distribution tube 3 rolls down into the soil hole formed by the insertion of the fertilizer distribution tube 3 under the action of gravity, completing the falling and fertilizing process of the fertilizer. The falling hole of the fertilizer is squeezed by the fertilizer distribution tube 3 when it is inserted into the soil, and the inner wall of the hole is relatively solid, which further reduces the looseness of the soil in the area where the fertilizer is applied to the sandy land, reduces the decomposition and loss rate of the fertilizer, and increases the duration of the fertilizer effect. At the same time, the cutting method is used for fixed-point and fixed-depth fertilization, and the fertilizer action area can be adaptively adjusted according to the growth stage of wheat to avoid the occurrence of "seedling burn".

[0041] Furthermore, in order to further reduce the influence of loose sandy soil on the fertilizer effect duration, Figure 2 , Figure 4 and Figure 6As shown, the gravity hammer 5 is located above the fertilizer distribution pipe 3, the lower part of the gravity hammer 5 is sleeved with a wear-resistant roller sleeve 51, a thrust spring 52 is connected between the middle part of the gravity hammer 5 and the ground-lift frame 4, and a power shaft 7 is rotatably installed on the upper part of the fertilizer frame 1. Power wheels 71 are symmetrically installed on the power shaft 7 and one of the walking wheels, and the two power wheels 71 are connected by a power chain 72. An intermittent gear 73 is fixedly installed on the power shaft 7. The intermittent gear 73 is an incomplete gear structure. A single chain 74 is meshed and installed on the intermittent gear 73. One end of the single chain 74 is fixedly connected to the gravity hammer 5, and the other end of the single chain 74 is fixedly connected to the fertilizer frame 1 through a tension spring.

[0042] During operation, as the fertilizer spreader frame 1 moves in the field, the meshing transmission between the power wheel 71 and the power chain 72 can drive the power shaft 7 to rotate, and the power shaft 7 drives the intermittent gear 73 to rotate. Since the intermittent gear 73 is an incomplete gear structure, when it is in meshing state with the single chain 74, the single chain 74 is pulled to move by the pulling force, and the gravity hammer 5 is pulled upward by the single chain 74, and the compression deformation degree of the thrust spring 52 is increased. At this time, the fertilizer distribution pipe 3 is inserted into the soil for fertilizer. After the fertilization is completed, along with the further movement of the fertilizer rack 1, the intermittent gear 73 temporarily disengages from the single chain 74 after turning to a predetermined angle. Then, under the elastic reset push of the thrust spring 52, the gravity hammer 5 quickly moves downward and knocks the soil above the hole formed after the fertilizer distribution pipe 3 is moved out, causing it to collapse and compensating the filling hole of the fertilizer, further realizing the covering operation of the fertilizer to reduce its exposure and avoid nutrient loss caused by rapid decomposition of the fertilizer. Reduce the permeability of the soil in the area where the fertilizer is located, thereby increasing its fertilizer effect duration, reducing the number of fertilizations, and improving the stability of wheat growth.

[0043] In addition, the present invention also provides a fertilizer compatible with the wheat biofilm composite fertilizer fertilizing device, wherein the biofilm composite fertilizer is a granular fertilizer organically combining inorganic nutrient elements, organic matter and microorganisms.
