Description

Technical Field

[0001] This invention relates to the field of precision fertilization technology, and in particular to a fertilizer discharge device for precision hole fertilization. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material bases for agricultural production and mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers.

[0003] With the popularization of agricultural mechanization, the traditional method of manually spreading fertilizer has been eliminated in large-scale agricultural planting due to its low efficiency. By installing fertilizer dispensing equipment in the seeder, fertilizer can be spread into the planting furrows at the same time during the sowing process, which can greatly improve the efficiency of agricultural planting.

[0004] Chinese invention patent application number CN202410917712.3 describes a fertilizer-applying seeder that, through a combination of a furrowing shovel, baffle, soil-crushing blade, fertilizer bin, first connecting hole, second connecting hole, seeding pipe, rotary tiller, and covering plate, completes the tasks of furrowing, soil crushing, sowing, fertilizing, rotary tilling, and covering in one operation, greatly improving the efficiency of agricultural sowing and fertilization. However, during the sowing process, after the seeds are delivered into the furrow, the fertilizer also falls into the furrow. Since the seeder is constantly moving during operation, the fertilizer falls into the furrow in a straight line. This results in the fertilizer initially falling into the furrow being far from the seeds, which is not conducive to the seeds fully absorbing the fertilizer's fertility and thus adversely affects the growth and development of the seeds. Summary of the Invention

[0005] The purpose of this invention is to provide a precision fertilization device for hole application, which solves the problem mentioned in the background art that in the existing fertilization equipment, the fertilizer falls into the hole in a straight line during the fertilization process. This results in the fertilizer initially falling into the hole being far from the seeds, which is not conducive to the seeds fully absorbing the fertility of the fertilizer and has an adverse effect on the growth and development of the seeds.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fertilizer discharge device for precision hole fertilization, comprising multiple fixing components, wherein the fixing components are provided with fertilizer guiding components and auxiliary fertilizer application components, and the fixing components are also provided with seeding components;

[0007] The fertilizer guiding component is used to guide and transport fertilizer into the trench. The fertilizer guiding component includes a conveying box, and the conveying box has an inlet and a outlet on its side and bottom, respectively.

[0008] The auxiliary fertilization component includes a material distribution strip connected to the discharge port at the bottom of the conveying box. The length direction of the material distribution strip is perpendicular to the direction of travel of the device. A material distribution cavity is opened inside the material distribution strip. Multiple discharge holes are opened on the bottom wall of the material distribution cavity along the length direction of the material distribution strip. The auxiliary fertilization component also includes a pushing mechanism for pushing fertilizer into the trench.

[0009] Preferably, the fertilizer guiding component further includes a conveyor belt installed inside the conveyor box. The conveyor belt includes a first drive shaft, which is connected to the sowing component to achieve synchronous operation with the sowing component. The left and right ends of the first drive shaft pass through the left and right side walls of the conveyor box and extend to the outside of the conveyor box. Multiple fertilizer guiding scrapers are fixedly connected at equal intervals on the outer surface of the conveyor belt. The advantage of this arrangement is that seeds and fertilizer can be sent into the furrows synchronously, thereby achieving precise fertilizer discharge.

[0010] Preferably, the inner bottom wall of the dispensing chamber is an isosceles triangle, and the inclination angle of the inclined surface of the inner bottom wall of the dispensing chamber is not less than ten degrees. The advantage of this setting is that it can ensure that the spacing between the fertilizer and the seeds is consistent and small, which improves the absorption rate of fertilizer by the seeds and further improves the growth quality of the seeds.

[0011] Preferably, the width of the plurality of discharge holes gradually increases from the middle of the dispensing chamber to the left and right sides. The advantage of this design is that it can further prevent fertilizer from being discharged into the discharge holes near the middle of the dispensing chamber, thereby effectively improving the absorption rate of fertilizer by the seeds.

[0012] Preferably, the feeding mechanism includes two push plates symmetrically and movable at the bottom of the distribution strip. The feeding mechanism also includes a drive unit disposed on the distribution strip. The drive unit can drive the two push plates to move towards each other to push the fertilizer into the seed furrow. The advantage of this arrangement is that it ensures that all the fertilizer can be delivered into the seed furrow, ensuring the reliable operation of fertilization.

[0013] Preferably, the drive unit includes two sets of telescopic rods symmetrically fixedly connected to the left and right sides of the conveyor box. Two pull plates are symmetrically fixedly connected to the bottom ends of the two sets of telescopic rods. The drive unit also includes two drive wheels symmetrically fixedly sleeved on the first drive shaft. The outer edge of each drive wheel is parabolic. The outer edges of the two drive wheels respectively abut against the bottom surfaces of the two pull plates. The drive unit also includes two movable plates symmetrically slidably connected to the top of the distribution strip. Two sets of pull ropes are symmetrically fixedly connected between the sides of the two movable plates and the sides of the two pull plates that are far apart. Two first elastic elements are symmetrically fixedly connected between the sides of the two movable plates that are far apart and the top of the distribution strip. Two pairs of connecting rods are symmetrically fixedly connected to the bottom of the two movable plates. The bottom ends of the two pairs of connecting rods are respectively fixedly connected to two push plates. The advantage of this arrangement is that it can concentrate the fertilizer discharged each time into the seed furrow, ensuring that the fertilization work is carried out stably and orderly.

[0014] Preferably, the auxiliary fertilization component further includes a uniform distribution mechanism, which is used to uniformly push the fertilizer in the distribution chamber into multiple feeding holes. The uniform distribution mechanism includes two uniform distribution plates symmetrically movable and connected inside the distribution chamber. The uniform distribution mechanism also includes two pushing units symmetrically arranged on the distribution strip. The two uniform distribution plates are symmetrically connected to the two pushing units, and the two pushing units are symmetrically connected to the two movable plates. The advantage of this arrangement is that it can ensure that the fertilizer can fall evenly on the soil surface in the lateral direction, further ensuring the absorption rate of fertilizer by the seeds and improving the reliability of the device.

[0015] Preferably, the pushing unit includes two symmetrically arranged sliding cavities on the top of the distribution strip, both of which are connected to the distribution chamber. The pushing unit also includes sliding rods slidably connected in the sliding cavities. The bottom ends of the two sliding rods pass through the two sliding cavities and are fixedly connected to the top of the two equalizing plates, respectively. The top ends of the two sliding rods pass through the two sliding cavities and are symmetrically fixedly connected to the bottom of the two moving plates. The advantage of this arrangement is that it can orderly and stably push the fertilizer falling into the distribution chamber each time, ensuring the orderly progress of fertilizer discharge and ensuring the effectiveness and quality of fertilizer discharge and fertilization.

[0016] Preferably, the sowing assembly includes a second drive shaft, which is connected to the first drive shaft via a first belt and a first pulley. This arrangement allows sowing and fertilization to be carried out simultaneously, ensuring that each seed sown can absorb the fertilizer evenly and thus ensuring good seed growth and development.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. In this invention, by setting up material distribution blocks, material distribution chambers and multiple discharge holes, the fertilizer falling from the conveyor box can fall evenly in the horizontal direction. Then, the pushing mechanism can concentrate and push these fertilizers into the seed furrows, which can ensure that the spacing between the fertilizer and the seeds is consistent and small, improve the absorption rate of fertilizer by the seeds, and further improve the growth quality of the seeds.

[0019] 2. In this invention, the first drive shaft, the second drive shaft and the sowing component are connected by a transmission, which enables the first drive shaft and the sowing component to rotate synchronously. This allows the seeds and fertilizer to be delivered into the furrows at the same time, thereby achieving precise discharge of fertilizer, ensuring that the seeds can better absorb the fertility of the fertilizer, and ensuring that the seeds can grow and develop well.

[0020] 3. In this invention, the uniform feeding mechanism can evenly push the fertilizer falling at the bottom of the feeding chamber onto the bottom wall of the feeding chamber, ensuring that the fertilizer can fall evenly into multiple feeding holes, thereby ensuring that the fertilizer can fall evenly on the soil surface in the transverse direction, further ensuring the absorption rate of fertilizer by the seeds and improving the reliability of the device.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The seed inlet and the seed outlet are respectively connected to a seed inlet pipe 43 and a seed outlet pipe 44. The second drive shaft 41 is provided with multiple partitions in a ring at equal angles. The multiple partitions can intermittently and equally transport the seeds to the seed outlet and discharge them into the seed furrow through the seed outlet pipe 44 to complete the sowing work. The fixed component 1 is fixedly connected to a seed box 6. The top of the seed inlet pipe 43 is connected to the bottom of the seed box 6.

[0035] The fertilizer guiding component 2 is used to guide and transport fertilizer into the trench. The fertilizer guiding component 2 includes a conveying box 21. The conveying box 21 has an inlet and a outlet on its side and bottom, respectively. The inlet is connected to an inlet pipe 51, and the outlet is connected to an outlet pipe 25. The bottom end of the outlet pipe 25 is connected to the top of the distribution strip 31. The inlet pipe 51 is equipped with an inlet amount adjustment mechanism, which can adjust the amount of fertilizer fed into the inlet pipe 51, thereby achieving precise fertilizer discharge and improving the fertilization effect. The fertilizer box 5 is fixedly connected to the fixing component 1.

[0036] The auxiliary fertilization component 3 includes a material distribution strip 31 connected to the discharge port at the bottom of the conveying box 21. The length direction of the material distribution strip 31 is perpendicular to the direction of travel of the device. A material distribution cavity 32 is opened inside the material distribution strip 31. Multiple discharge holes 33 are opened on the bottom wall of the material distribution cavity 32 along the length direction of the material distribution strip 31. The auxiliary fertilization component 3 also includes a pushing mechanism 34, which is used to push fertilizer into the trench.

[0037] refer to Figures 6-8The fertilizer guiding component 2 also includes a conveyor belt 22 installed in the conveyor box 21. The conveyor belt 22 includes a first drive shaft 23. The first drive shaft 23 is connected to the sowing component 4 to achieve synchronous operation with the sowing component 4.

Multiple fertilizer guiding scrapers 24 are fixedly connected at equal intervals on the outer surface of the conveyor belt 22.

[0038] Specifically, the fertilizer is intermittently transported to the discharge port at the bottom of the conveying box 21 by the fertilizer guide scraper 24, and then the first drive shaft 23 and the sowing component 4 rotate synchronously, so that the seeds and fertilizer are sent into the furrow at the same time, thereby achieving precise discharge of fertilizer, ensuring that the seeds can better absorb the fertilizer fertility, and ensuring that the seeds can grow and develop well.

[0039] Example 2

[0040] According to Example 1, please refer to Figures 7-9 The inner bottom wall of the material distribution chamber 32 is an isosceles triangle, and the inclination angle of the inclined surface of the inner bottom wall of the material distribution chamber 32 is not less than ten degrees.

[0041] Specifically, the fertilizer slides at a relatively fast speed from the middle of the dispensing chamber 32 toward the left and right ends, thus preventing the fertilizer from being concentrated in the discharge hole 33 near the middle of the dispensing chamber 32 and ensuring the uniformity of fertilizer discharge. Then, the pushing mechanism 34 pushes the fertilizer, which is evenly distributed in a straight line, into the seed furrow, thus ensuring that the distance between the fertilizer and the seed is consistent and small, improving the absorption rate of fertilizer by the seed and further improving the growth quality of the seed.

[0042] refer to Figures 7-9 The width of the multiple feeding holes 33 gradually increases from the middle of the material distribution chamber 32 to the left and right sides.

[0043] Specifically, it can further prevent fertilizer from being discharged into the discharge hole 33 near the middle of the distribution chamber 32, effectively improving the absorption rate of fertilizer by the seeds.

[0044] refer to Figures 1-5 The feeding mechanism 34 includes two push plates 341 that are symmetrically connected to the bottom of the distribution strip 31. The feeding mechanism 34 also includes a drive unit 342 on the distribution strip 31. The drive unit 342 can drive the two push plates 341 to move towards each other to push the fertilizer into the seed furrow.

[0045] Specifically, the drive unit 342 pushes two push plates 341 to move simultaneously toward the seed furrow, thereby concentrating and pushing the fertilizer, which is evenly distributed laterally, into the furrow, ensuring that all the fertilizer is delivered into the seed furrow and guaranteeing the reliable operation of fertilization.

[0046] refer to Figures 3-5 The drive unit 342 includes two sets of telescopic rods 3421 symmetrically fixedly connected to the left and right sides of the conveyor box 21. Two pull plates 3422 are symmetrically fixedly connected to the bottom ends of the two sets of telescopic rods 3421. The drive unit 342 also includes two drive wheels 3423 symmetrically fixedly sleeved on the first drive shaft 23. The outer edge of the drive wheels 3423 is parabolic in shape. The outer edges of the two drive wheels 3423 respectively abut against the bottom surfaces of the two pull plates 3422. The drive unit 342 also includes symmetrical sliding... Two movable plates 3424 are connected to the top of the material distribution block 31. Two sets of pull ropes 3425 are symmetrically fixedly connected between the sides of the two movable plates 3424 and the sides of the two pull plates 3422 that are far apart. Two first elastic elements 3426 are symmetrically fixedly connected between the sides of the two movable plates 3424 that are far apart and the top of the material distribution block 31. Two pairs of connecting rods 3411 are symmetrically fixedly connected to the bottom of the two movable plates 3424. The bottom ends of the two pairs of connecting rods 3411 are respectively fixedly connected to the two push plates 341.

[0047] Specifically, as the drive wheel 3423 rotates and the elastic force of the first elastic element 3426 is combined, the pull plate 3422 can be pushed up and down to move back and forth. The pull plate 3422 drives the two moving plates 3424 to move closer or further away from each other through the pull rope 3425, so that the fertilizer discharged each time can be concentrated and pushed into the seed furrow, ensuring that the fertilization work is carried out stably and orderly.

[0048] Example 3

[0049] Please refer to Example 1 or 2. Figures 6-9 The auxiliary fertilization component 3 also includes a material equalization mechanism 35, which is used to evenly push the fertilizer in the distribution chamber 32 into multiple discharge holes 33. The material equalization mechanism 35 includes two material equalization plates 351 that are symmetrically moved and connected inside the distribution chamber 32. The material equalization mechanism 35 also includes two pushing units 352 that are symmetrically arranged on the distribution strip 31. The two material equalization plates 351 are symmetrically connected to the two pushing units 352, and the two pushing units 352 are symmetrically connected to the two moving plates 3424.

[0050] Specifically, by driving the two equalizing plates 351 to move back and forth towards each other or away from each other in the distributing chamber 32, the fertilizer falling at the bottom of the distributing chamber 32 can be evenly pushed onto the bottom wall of the distributing chamber 32, ensuring that the fertilizer can fall evenly into the multiple discharging holes 33, thereby ensuring that the fertilizer can fall evenly on the soil surface in the lateral direction, further ensuring the absorption rate of fertilizer by the seeds and improving the reliability of the device.

[0051] refer to Figure 9The pushing unit 352 includes two sliding cavities 3521 symmetrically opened on the top of the material distribution block 31. Both sliding cavities 3521 are connected to the material distribution cavity 32. The pushing unit 352 also includes sliding rods 3522 slidably connected in the sliding cavities 3521. The bottom ends of the two sliding rods 3522 pass through the two sliding cavities 3521 respectively and are fixedly connected to the top of the two material distribution plates 351 respectively. The top ends of the two sliding rods 3522 pass through the two sliding cavities 3521 respectively and are symmetrically fixedly connected to the bottom of the two moving plates 3424.

[0052] Specifically, through the slide bar 3522 and the slide cavity 3521, the two equalizing plates 351 can move synchronously with the two moving plates 3424, thereby orderly and stably pushing the fertilizer that falls into the distribution cavity 32 each time, ensuring the orderly progress of fertilizer discharge work and ensuring the effect and quality of fertilizer discharge and fertilization work.

[0053] refer to Figures 1-5 The seeding assembly 4 includes a second drive shaft 41, which is connected to the first drive shaft 23 via a first belt 42 and a first pulley.

[0054] Specifically, this allows sowing and fertilization to be carried out simultaneously, ensuring that each seed sown can absorb the fertilizer evenly and thus guaranteeing good seed growth and development.
