Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to an agricultural planting mechanical fertilization device. Background Art

[0002] Fertilization is an essential step in agricultural planting and a necessary condition for crop growth. Scientific fertilization can improve the yield and quality of crops. Scientific fertilization can also reduce the amount of fertilizer used, reduce costs, and maximize the use of fertilizers. Common fertilization problems in agricultural production today include: 1) Fertilization amount cannot be controlled: excessive fertilization leads to fertilizer waste and negative impact on soil; 2) Large-particle fertilization: Block fertilizers and large-particle fertilizers take a long time to melt. As rainwater erodes and washes away, the soil does not have time to absorb the nutrients. The unmelted fertilizers will be carried away with the rainwater, resulting in insufficient nutrients being absorbed by the soil. Fertilizers need to be supplemented, and secondary fertilization increases costs. 3) Fertilization in arid areas: Without sufficient rainfall, fertilizers cannot be diluted with water, resulting in a longer melting time, so that the soil cannot get nutrients in time; or the nutrient loss of the soil is greater than the absorption per unit time, and the fertilization cannot achieve the absorption effect, resulting in ineffective fertilization. Crops cannot absorb enough nutrients, which still leads to reduced production; Therefore, how to effectively use fertilizers in agricultural planting is a problem that needs to be solved. Based on the above reasons, I proposed an agricultural planting mechanical fertilization device. Summary of the invention

During the process of moving, they cross the ground and turn over the soil ridges. Moreover, the inclination directions of the front and rear adjacent plow blades 10-2 are opposite, so that the soil can be turned back and forth during the process of moving, making the soil more loose. At the same time, a leveling wheel 10-3 is arranged at the rear end of the tractor frame 10. The loosened soil is leveled by dragging and rolling the leveling wheel 10-3, realizing the integrated operation of turning over the soil, fertilizing and leveling, which is very convenient.

The generator 10-4 is provided with a pulley, and the generator 10-4 is connected to the traction vehicle through the pulley and the belt. An air compressor 10-5 is also arranged on the top front side of the traction frame 10; The generator 10-4 is connected to the tractor through a belt transmission, and generates electricity during the operation of the tractor to supply power to the electrical equipment on the tractor frame 10. By generating electricity through the tractor, it is possible to avoid carrying an additional power source, which is more convenient to use during actual farming. The air compressor 10-5 acts as an air pump to provide a driving air source for the fertilizer powder to be discharged. The fertilizer pretreatment box 20 includes a fertilizer storage box 201, a grinding box 202, and a feeding base 203, and a one-way channel is provided between the fertilizer storage box 201, the grinding box 202, and the feeding base 203, which are connected in sequence; a grinding motor 201-1 is fixed to the front side of the fertilizer storage box 201, and the inner cavity of the fertilizer storage box 201 is in an inclined funnel shape, and a feeding shaft 201-4 is provided at the bottom of the funnel shape; The front end of the unloading shaft 201-4 is connected to a unloading motor 201-3, and the unloading motor 201-3 is fixed on the outer wall of the fertilizer storage box 201; the bottom of the fertilizer storage box 201 is provided with two unloading bins, and each unloading bin is provided with a grinding box 202; The unloading shaft 201-4 is a two-section shaft, each section of the shaft corresponds to the discharge bin below, and a unloading trough 201-4-1 is symmetrically provided on the surface of the unloading shaft 201-4; when the unloading shaft 201-4 rotates, the unloading trough 201-4-1 is filled with fertilizer in the fertilizer storage box 201, and the fertilizer is poured out from below as the unloading shaft 201-4 rotates; A vibration motor 201-4-2 is provided between the symmetrical feeding troughs 201-4-1. When the vibration motor 201-4-2 vibrates, the filling or pouring of fertilizer in the feeding trough 201-4-1 can be accelerated. A grinding mechanism is provided in the middle of the inner cavity of the grinding box 202, and the grinding mechanism includes a driving shaft 202-1, a grinding cutter head 202-2, and a grinding base 202-3. The driving shaft 202-1 extends upward to the top position of the fertilizer storage box 201, and a gear plate is provided at the top of the driving shaft 202-1. The grinding motor 201-1 and the driving shaft 202-1 on the same side are parallel to each other, and a gear plate is also provided at the top of the grinding motor 201-1. A transmission chain is installed between the gear plate of the grinding motor 201-1 and the gear plate of the driving shaft 202-1, and power transmission is completed through the transmission chain; bearings are provided at the connection between the driving shaft 202-1 and the fertilizer storage box 201; The grinding base 202-3 is fixed in the inner cavity of the grinding box 202, and the grinding head 202-2 is inserted into the grinding base 202-3. The grinding head 202-2 includes an upper propulsion screw sheet and a bottom grinding tooth. The inner wall of the grinding base 202-3 is also provided with a grinding tooth. The propulsion screw sheet pushes the fertilizer downward, and the fertilizer is turned into fine fertilizer powder after being ground by the grinding head 202-2 and the grinding base 202-3. The top of the grinding base 202-3 is an outward-expanding trumpet, and the bottom of the grinding blade 202-2 is a cone with a small top and a large bottom. During grinding, the fertilizer can be continuously pushed downward by the rotation of the grinding blade 202-2. The unloading base 203 is arranged below the grinding box 202 and receives the fertilizer powder dropped by grinding. A push rod 202-4 is installed at the bottom of the grinding cutter head 202-2 and rotates synchronously with the driving shaft 202-1. The push rod 202-4 is provided with a spiral blade to push the fertilizer powder on the top downward when rotating. A discharge chamber 203-3 is provided at the inner base of the material discharging base 203, and the fertilizer powder falling from the upper side all falls into the discharge chamber 203-3, and a discharge valve 203-2 is installed in the channel above the discharge chamber 203-3, and a fertilizer head 203-1 is symmetrically provided at the front end of the material discharging base 203, and a blowing valve 203-4 is provided at the rear end of the discharge chamber 203-3. The blowing valve 203-4 is connected with the air compressor 10-5 through a pipeline, and air is blown into the discharge chamber 203-3 through the air compressor 10-5, and the fertilizer powder is blown out by the airflow to achieve the purpose of fertilization; The two fertilizer storage boxes 201 are provided with closed covers 201-2 on opposite sides. The closed covers 201-2 are movably installed through hinges. When flipped upward, the fertilizer storage boxes 201 are covered. When flipped downward, the top of the fertilizer storage boxes 201 is opened to facilitate the injection of fertilizer. The driving shaft 202-1 is installed on a cover plate on the top of the fertilizer storage box 201 that is biased to the other side and cannot be opened, and the driving shaft 202-1 does not contact the closed covers 201-2. When in use, the fertilizer is poured into the fertilizer storage box 201, and then the unloading motor 201-3 is started to start the unloading work. The working end of the unloading motor 201-3 is equipped with a unloading shaft 201-4. The unloading shaft 201-4 is driven by the unloading motor 201-3 to rotate at a uniform speed in the bottom channel of the inner cavity of the fertilizer storage box 201. When it rotates to the top, the unloading trough 201-4-1 is filled with fertilizer and continues to rotate downward with the filled fertilizer. When the unloading trough 201-4-1 rotates to the bottom of the channel, the fertilizer falls downward under the action of gravity; at the same time, a vibration motor 201-4-2 is arranged between the front and rear adjacent unloading troughs 201-4-1, and the fertilizer particles can be shaken off by vibration. Similarly, the fertilizer can be filled more evenly and quickly during filling. The two-stage feeding shaft 201-4 can feed the two grinding boxes 202 in a targeted manner. At the same time, the feeding trough 201-4-1 can be used to achieve quantitative feeding. The filling amount of the feeding trough 201-4-1 and the speed of the feeding motor 201-3 can control the progress of feeding, which is very convenient. Fertilizer is put into the grinding box 202, and the granular fertilizer is ground and crushed into fertilizer powder by the grinding mechanism. The operating principle is that the grinding motor 201-1 drives the driving shaft 202-1 to rotate, and the driving shaft 202-1 synchronously drives the grinding head 202-2 at the bottom to rotate, and the propulsion screw piece on the upper part of the grinding head 202-2 brings the upper fertilizer to the bottom through rotation, and the granular fertilizer is ground into fertilizer powder through the continuous friction between the bottom of the grinding head 202-2 and the grinding bottom 202-3. The degree of grinding can be selected according to actual needs. Grinding heads with different specifications of teeth are selected. At the same time, the size of the gap between the grinding head 202-2 and the grinding base 202-3 is also a factor that affects the coarseness of grinding. These can be specifically configured according to needs when in use, and no further details are given here; The granular fertilizer after grinding becomes fertilizer powder. At this time, the fertilizer powder will be easier for the soil to absorb when it is spread. The soil fertility will be improved faster after spreading. It is very necessary for crops that need to be planted in a hurry (crops that need to be planted before the weather changes. Continuous bad weather may affect sowing, which will affect the best growth period of crops, causing late maturity and easy reduction of crop yield). It can gain more growth time in good weather. At the same time, the fertilizer is absorbed faster, which can reduce the waste of fertilizer when rain comes and avoid rain washing away too much fertilizer. A push rod 202-4 is provided at the bottom of the grinding head 202-2. When the push rod 202-4 rotates synchronously with the driving shaft 202-1, the spiral blades thereon push the fertilizer powder downward continuously. The bottom of the push rod 202-4 extends into the inner cavity channel of the unloading base 203. A discharge cavity 203-3 is provided at the bottom of the inner cavity of the unloading base 203. The discharge valve 203-2 is opened to connect the upper channel with the discharge valve 203-2, so that the fertilizer falls naturally. (The discharge valve 203-2 is a large-caliber electric valve, which is a prior art. Any large-caliber electric valve that can circulate dust on the market can be used, which will not be described here.) The fertilizing head 203-1 is connected with the discharge chamber 203-3. The front end of the fertilizing head 203-1 is provided with a powder outlet 203-1-3, which is inclined downward. The rear end of the discharge chamber 203-3 is provided with a blow valve 203-4, which is connected to the air compressor 10-5 through a pipeline, and the air compressor 10-5 provides an air source, and the air flow blows the fallen fertilizer powder to blow the fertilizer powder out from the powder outlet 203-1-3. The discharge chamber 203-3 is also inclined forward to facilitate better discharge when blowing. Since the fertilizer head 203-1 is facing the ground, the blown fertilizer powder is sprayed on the ground. At the same time, the fertilizer powder dropped from the discharge chamber 203-3 cooperates with the blowing speed, grinding speed, feeding speed, and the traveling speed of the tractor, so that automatic fertilization can be achieved. By controlling the speed, the fertilizer can be evenly spread on the ground. Since the fertilizer head 203-1 is arranged in front of the traveling direction of the plow blade 10-2, the plow blade 10-2 will repeatedly turn the fertilized soil after fertilization, and cover the fertilizer powder under the soil, thereby completing the fertilization work of this part of the soil. It should be noted that a grid 203-1-1 is provided in the powder outlet 203-1-3. The grid 203-1-1 prevents the fertilizer powder from splashing too far when it is discharged, and keeps it at the fertilization location. The function of the grid 203-1-1 is to prevent the blown fertilizer powder from being blown out in the form of powder balls, and to achieve uniform spraying through the cutting of the grid 203-1-1. An inclined protrusion 203-1-2 is provided between adjacent powder outlets 203-1-3 to block the fertilizer powder blown to both sides, and an inclined protrusion 203-1-2 is also provided between adjacent fertilizer heads 203-1; the inclined protrusion 203-1-2 functions as a cutting surface to cut the fertilizer powder blown to the powder outlets 203-1-3 on both sides to prevent the fertilizer powder from accumulating in the inner cavity; the inclined protrusion 203-1-2 is provided at the outlet, and can also gather the wind by changing the direction of the wind to form a wind surge, so that the wind has more driving force at the outlet to prevent the outlet from being blocked; This solution is also designed with water and fertilizer generation function, aiming to further improve fertilization efficiency, increase soil absorption rate, and complete the two operations of irrigation and fertilization; A material guide pipe 203-5 is installed at the bottom of the discharge base 203, and the discharge chamber 203-3 is connected to the water-fertilizer generating box 30 through the material guide pipe 203-5. A discharge valve 203-2 is also arranged at the position where the material guide pipe 203-5 is connected to the discharge chamber 203-3. The lower discharge valve 203-2 is arranged just below the upper discharge valve 203-2. At the same time, due to the height of the discharge chamber 203-3 (the discharge chamber 203-3 is flat), the two discharge valves 203-2 are not far apart, so the vertical feeding of fertilizer powder can be achieved without blowing. At the same time, the installation position of the lower discharge valve 203-2 is slightly downward, presenting a concave flared arc surface, so that the fertilizer powder gathers at the lower discharge valve 203-2 under mechanical vibration, and is put into the mixing chamber 30-4 through the material guide pipe 203-5; An oscillator 50 is provided on the material guide pipe 203-5, and the fertilizer powder can be accelerated to pass through the material guide pipe 203-5 by vibration; The inner cavity of the water-fertilizer generating box 30 is composed of a water storage cavity 30-3, a mixing cavity 30-4 and an installation cavity. The water storage cavity 30-3 is arranged near the front end of the traction frame 10, the mixing cavity 30-4 is arranged at the rear side of the traction frame 10, and the top of the mixing cavity 30-4 is the installation cavity. A water tower 30-1 is installed at the rear side of the top of the water-fertilizer generating box 30, a sewage suction pump 30-6 is arranged in the installation cavity, and the upper and lower ends of the sewage suction pump 30-6 are respectively connected to the water tower 30-1 and the mixing cavity 30-4 through pipelines, and a water pump 30-5 is arranged near the water storage cavity 30-3 in the installation cavity, and the two ends of the water pump 30-5 are respectively connected to the water storage cavity 30-3 and the mixing cavity 30-4; A stirring motor 30-7 is provided at the bottom of the mixing chamber 30-4. The top of the stirring motor 30-7 and the bottom pipe of the sewage suction pump 30-6 are staggered and do not contact each other. The working end of the stirring motor 30-7 extends into the mixing chamber 30-4. When the fertilizer powder enters the mixing chamber 30-4 along the material guide pipe 203-5 and the water flows along the water pump 30-5, the stirring motor 30-7 is started to accelerate the stirring and mixing to form water fertilizer, and then the water fertilizer is pumped into the water tower 30-1 through the sewage suction pump 30-6. A plurality of water pipes 30-2 are evenly connected to the rear side of the water tower 30-1, and the water fertilizer is sprinkled on the ground through the water pipes 30-2. A support frame 40 is welded to the top rear side of the traction frame 10. The support frame 40 is arranged horizontally, and placement notches are evenly opened on the support frame 40. The water pipes 30-2 are placed on the placement notches in sequence, so that the spraying is more uniform, and the irrigation-fertilization synchronization operation is realized, which is very convenient.
