Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and in particular to an agricultural planting mechanical fertilizing 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.

[0003] Common fertilization problems encountered in agricultural production today include: 1) Failure to control the amount of fertilizer applied: Excessive fertilization leads to fertilizer waste and negative impacts on the soil;

[0004] 2) Large-particle fertilization: Block fertilizers and large-particle fertilizers take a long time to melt. As rainwater erodes and washes away the unmelted fertilizer, the soil has no time to absorb it. The unmelted fertilizer will be carried away by the rainwater, resulting in insufficient nutrient absorption by the soil. This requires additional fertilizer, and secondary fertilization increases costs.

[0005] 3) Fertilization in arid areas: Without sufficient rainfall, fertilizers cannot be diluted with water, resulting in a longer melting time and a delay in the timely nutrient absorption of the soil. Alternatively, the soil loses more nutrients than it absorbs per unit time, preventing the absorption of nutrients effectively. This results in ineffective fertilization, and crops cannot absorb sufficient nutrients, which can still lead to yield reductions.

[0006] Therefore, how to effectively utilize chemical 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

[0052] See also Figures 1-9 This solution provides the following technical solutions: an agricultural planting mechanical fertilization device with a solid-liquid integrated fertilization effect, which grinds large-particle fertilizer into fertilizer powder by grinding, and then flexibly switches between solid and liquid fertilization through the fertilizer powder to improve fertilization efficiency, while accelerating soil absorption and reducing fertility loss caused by natural volatilization and rainwater erosion. It includes a traction frame 10, and the traction frame 10 is provided with a fertilizer pretreatment box 20 and a water-fertilizer generation box 30. The fertilizer pretreatment boxes 20 are symmetrically arranged on the left and right sides of the top of the traction frame 10, and the water-fertilizer generation box 30 is arranged in the middle of the top of the traction frame 10. The details are as follows:

[0053] A plow blade mounting frame 10-1 is welded to the rear side of the tractor frame 10. Bowl-shaped plow blades 10-2 are evenly arranged on the plow blade mounting frame 10-1. A leveling wheel 10-3 is installed on the outermost side of the plow blade mounting frame 10-1. The plow blades 10-2 are provided in two groups, one near the front end of the tractor frame 10 and the other near the leveling wheel 10-3. A wheel is provided between the two groups of plow blades 10-2.

[0054] The tractor frame 10 is mounted on the rear of the tractor and is driven forward by the tractor; two groups of bowl-shaped plow blades 10-2 are provided at the front and rear, one group in front of the wheels and the other group behind the wheels. During the movement, they cut across the ground and turn over the soil ridges. Moreover, the tilt directions of the adjacent plow blades 10-2 are opposite, so that the soil can be turned back and forth during the movement, making the soil more loose. At the same time, a leveling wheel 10-3 is provided 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.

[0055] The front end of the traction frame 10 is connected to the tractor. A generator 10-4 is provided on the top front side of the traction frame 10. The generator 10-4 is provided with a pulley, and the generator 10-4 is connected to the tractor through the pulley and belt. An air compressor 10-5 is also provided on the top front side of the traction frame 10.

[0056] The generator 10-4 is drivingly connected to the tractor through a belt, generates electricity during the operation of the tractor, and supplies power to the electrical equipment on the tractor frame 10. By generating electricity through the work of the tractor, it is possible to avoid carrying an extra power source, making it more convenient to use during actual tillage operations; the air compressor 10-5 serves as an air pump to provide a driving air source for the discharge of fertilizer powder.

[0057] The fertilizer pretreatment box 20 includes a fertilizer storage box 201, a grinding box 202, and a blanking base 203, and a one-way channel is provided between the fertilizer storage box 201, the grinding box 202, and the blanking base 203 to connect them in sequence; a grinding motor 201-1 is fixed on the front side of the fertilizer storage box 201. The inner cavity of the fertilizer storage box 201 is in an inclined funnel shape, and a blanking shaft 201-4 is provided at the bottom of the funnel shape.

[0058] The front end of the blanking shaft 201-4 is connected to a blanking motor 201-3, and the blanking motor 201-3 is fixed on the outer wall of the fertilizer storage box 201; two discharge bins are provided at the bottom of the fertilizer storage box 201, and each discharge bin is provided with a grinding box 202.

[0059] The blanking shaft 201-4 is a two-section shaft body, and each section of the shaft body corresponds to the lower discharge bin respectively. Blanking grooves 201-4-1 are symmetrically arranged on the surface of the blanking shaft 201-4; when the blanking shaft 201-4 rotates, the blanking grooves 201-4-1 are filled with fertilizer in the fertilizer storage box 201 and the fertilizer is poured out below as it rotates.

[0060] A vibration motor 201-4-2 is provided between the symmetric blanking grooves 201-4-1. When the vibration motor 201-4-2 vibrates, it can accelerate the filling or pouring of fertilizer in the blanking grooves 201-4-1.

[0061] A grinding mechanism is provided in the middle of the inner cavity of the grinding box 202. The grinding mechanism includes a drive shaft 202-1, grinding cutter heads 202-2, and a grinding base 202-3. The drive shaft 202-1 extends upward to the top position of the fertilizer storage box 201, and a gear disc is provided at the top end of the drive shaft 202-1. The grinding motor 201-1 on the same side is parallel to the drive shaft 202-1, and a gear disc is also provided at the top of the grinding motor 201-1. A transmission chain is installed between the gear disc of the grinding motor 201-1 and the gear disc of the drive shaft 202-1, and power transmission is completed through the transmission chain; bearings are provided at the connection between the drive shaft 202-1 and the fertilizer storage box 201.

[0062] 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 a propulsion screw piece at the top and grinding teeth at the bottom. The inner wall of the grinding base 202-3 is also provided with grinding teeth. The propulsion screw piece pushes the fertilizer downward, and the fertilizer is ground into fine fertilizer powder by the grinding head 202-2 and the grinding base 202-3.

[0063] The top of the grinding base 202-3 is an outward-flared trumpet, and the bottom of the grinding head 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 head 202-2.

[0064] The feeding base 203 is arranged below the grinding box 202 and receives the fertilizer powder dropped from the grinding. A propulsion rod 202-4 is installed at the bottom of the grinding head 202-2 and rotates synchronously with the drive shaft 202-1. The propulsion rod 202-4 is provided with a spiral blade, which pushes the fertilizer powder downward when it rotates.

[0065] A discharge chamber 203-3 is provided at the inner base of the discharge base 203. The fertilizer powder falling from above falls into the discharge chamber 203-3. A discharge valve 203-2 is installed in the channel above the discharge chamber 203-3. A fertilizer head 203-1 is symmetrically provided at the front end of the discharge base 203. A blow valve 203-4 is provided at the rear end of the discharge chamber 203-3. The blow valve 203-4 is connected to the air compressor 10-5 through a pipeline. Air is blown into the discharge chamber 203-3 through the air compressor 10-5, and the fertilizer powder is blown out by the air flow to achieve the purpose of fertilization.

[0066] The two fertilizer storage boxes 201 are each provided with a closed cover 201-2 on opposite sides. The closed cover 201-2 is movably mounted via a hinge. When flipped upward, it covers the fertilizer storage box 201. When flipped downward, it opens the top of the fertilizer storage box 201 to facilitate the injection of fertilizer. The drive shaft 202-1 is mounted on a cover plate on the top of the fertilizer storage box 201 that is tilted to the other side and cannot be opened. The drive shaft 202-1 does not contact the closed cover 201-2.

[0067] When in use, fertilizer is poured into the fertilizer storage box 201, and then the unloading motor 201-3 is started to start unloading. 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 chute 201-4-1 is filled with fertilizer and continues to rotate downward with the filled fertilizer. When the unloading chute 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 provided between the front and rear adjacent unloading chutes 201-4-1, which can shake off the fertilizer particles by vibration. Similarly, the fertilizer can be filled more evenly and quickly during filling.

[0068] 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 realize quantitative feeding. The filling amount of the feeding trough 201-4-1 and the speed of the feeding motor 201-3 can control the feeding progress, which is very convenient.

[0069] Fertilizer is put into the grinding box 202, and the grinding mechanism grinds and breaks the granular fertilizer into fertilizer powder. Its operating principle is that the grinding motor 201-1 drives the drive shaft 202-1 to rotate, and the drive shaft 202-1 synchronously drives the grinding head 202-2 at the bottom to rotate. 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 also a factor that affects the coarseness of grinding. These can be specifically configured according to needs during use, and will not be described in detail here.

[0070] After grinding, the granular fertilizer becomes fertilizer powder. At this time, the fertilizer powder will be easier for the soil to absorb when it is sown. After sowing, the soil fertility will be improved faster. It is very necessary for crops that need to be planted before the weather changes. (Continued bad weather may affect sowing, which will affect the optimal growth period of the crops, causing late maturity and easy crop yield reduction). 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 prevent rain from washing away too much fertilizer.

[0071] A push rod 202-4 is provided at the bottom of the grinding tool head 202-2. When the push rod 202-4 rotates synchronously with the drive shaft 202-1, the spiral blades thereon continuously push the fertilizer powder downward. The bottom of the push rod 202-4 extends into the inner cavity channel of the blanking base 203. An outlet cavity 203-3 is opened at the bottom of the inner cavity of the blanking base 203. Opening the outlet valve 203-2 can connect the upper channel with the outlet valve 203-2, allowing the fertilizer to fall naturally. (The outlet valve 203-2 is a large-diameter electric valve, which is an existing technology. Any large-diameter electric valve that can allow dust to flow in the market can be used, and will not be elaborated here);

[0072] The fertilizer application head 203-1 is interconnected with the outlet cavity 203-3. The front end of the fertilizer application head 203-1 is provided with a powder outlet 203-1-3, and the powder outlet 203-1-3 is inclined downward; a blowing valve 203-4 is provided at the rear end of the outlet cavity 203-3. The blowing valve 203-4 is connected to the air compressor 10-5 through a pipeline, and the air compressor 10-5 provides the air source. The falling fertilizer powder is blown by the air flow, and the fertilizer powder is blown out from the powder outlet 203-1-3. The outlet cavity 203-3 is also inclined forward, which is convenient for better discharging during blowing; since the fertilizer application head 203-1 faces the ground, the blown fertilizer powder is sprayed on the ground. The fertilizer powder falling in the outlet cavity 203-3 at the same time is coordinated with the blowing speed, grinding speed, blanking speed, and traveling speed of the tractor, and automatic fertilization can be achieved. By controlling the speed, the fertilizer can be evenly spread on the ground. Since the fertilizer application head 203-1 is arranged in front of the advancing direction of the plow blade 10-2, after fertilization, the plow blade 10-2 repeatedly turns over the fertilized soil, covering the fertilizer powder under the soil and completing the fertilization work of this part of the soil;

[0073] 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 discharging, keeping it at the fertilization position; the function of the grid 203-1-1 is to prevent the blown fertilizer powder from being blown out in the form of powder clusters, and through the cutting of the grid 203-1-1, uniform spraying is achieved;

[0074] An inclined surface protrusion 203-1-2 is provided between adjacent powder outlets 203-1-3 to block the blown fertilizer powder to both sides, and inclined surface protrusions 203-1-2 are also provided between adjacent fertilizer application heads 203-1; the function of the inclined surface protrusion 203-1-2 is a cutting surface, cutting the blown fertilizer powder to the powder outlets 203-1-3 on both sides to prevent the fertilizer powder from accumulating in the inner cavity; the inclined surface 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, giving the wind more driving force at the outlet to prevent blockage of the outlet;

[0075] This solution also designs a function of generating water-fertilizer, aiming to further improve the fertilization efficiency, increase the soil absorption rate, and complete two operations of irrigation and fertilization.

[0076] A material guiding pipe 203-5 is installed at the bottom of the blanking base 203. The discharging cavity 203-3 is connected to the water-fertilizer generating tank 30 through the material guiding pipe 203-5. An outlet valve 203-2 is also set at the position where the material guiding pipe 203-5 is connected to the discharging cavity 203-3. The lower outlet valve 203-2 is set directly below the upper outlet valve 203-2. At the same time, limited by the height of the discharging cavity 203-3 (the discharging cavity 203-3 is flat), the two outlet valves 203-2 are not far apart. Therefore, vertical feeding of fertilizer powder can be achieved without blowing. At the same time, the installation position of the lower outlet valve 203-2 is slightly downward, presenting a concave flared arc surface. Under mechanical vibration, the fertilizer powder gathers towards the lower outlet valve 203-2 and is put into the mixing cavity 30-4 through the material guiding pipe 203-5.

[0077] An oscillator 50 is set on the material guiding pipe 203-5. Vibration can accelerate the passage of fertilizer powder in the material guiding pipe 203-5.

[0078] The inner cavity of the water-fertilizer generating tank 30 consists of a water storage cavity 30-3, a mixing cavity 30-4 and an installation cavity. The water storage cavity 30-3 is set at a position close to the front end of the towing frame 10. The mixing cavity 30-4 is set at a position behind the towing frame 10. The top position of the mixing cavity 30-4 is the installation cavity.

[0079] A water tower 30-1 is installed at the rear side of the top of the water-fertilizer generating tank 30. A sewage suction pump 30-6 is set in the installation cavity. The upper and lower ends of the sewage suction pump 30-6 are connected to the water tower 30-1 and the mixing cavity 30-4 respectively through pipes. A water pump 30-5 is set at a position of the installation cavity close to the water storage cavity 30-3.
