Description

Technical Field

[0001] The invention relates to the technical field of farmland fertilization, in particular to a farmland deep fertilization device. Background Art

[0002] Fertilizer spreaders are commonly used agricultural machinery used to apply fertilizer quantitatively and evenly to farmland. They typically consist of a frame, a fertilizer tank, a fertilizer mechanism for discharging fertilizer quantitatively, and a trenching mechanism for digging trenches. Fertilizer spreaders are typically equipped with wheels or tracks, allowing them to travel across the farmland to apply fertilizer to different areas. Depending on whether the frame is powered, existing fertilizer spreaders can be categorized as hand-push and vehicle-mounted. As the fertilizer spreader moves along the edge of a crop to be fertilized, the trenching mechanism digs a trench, which it then deposits an appropriate amount of fertilizer into, achieving the desired fertilization goal.

[0003] During use, existing fertilizer spreaders often only spread fertilizer on the soil surface, or put fertilizer into the grooves opened by the trenching mechanism. The fertilizer cannot be integrated into the soil or cannot penetrate deep into the soil, resulting in the inability to improve the internal environment of the soil. In addition, before the fertilizer dissolves into the soil, a certain amount of fertilizer may volatilize due to its own properties, resulting in a decrease in the actual amount of fertilizer dissolved in the soil. The soil does not receive enough fertilizer, resulting in poor fertilization effect and even crop yield reduction. For this reason, we propose a deep fertilization equipment for farmland.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention utilizes the cooperation of a screw rod and a limit seat so that the first slide bar drives the plow blade to rise and fall, and adjusts the height of the plow blade to facilitate furrowing of different depths in different soils. At the same time, the elastic force of the spring pushes one end of the plow blade downward to maintain a good furrowing effect. When the plow blade encounters a relatively hard stone, one end of the plow blade rotates upward to compress the spring, thereby improving the smoothness of the plow blade furrowing process.

[0018] The present invention utilizes a knob to drive the telescopic rod and the threaded disk to rotate synchronously. The telescopic rod is extended and retracted through the cooperation of the threaded disk and the threaded groove. At the same time, the threaded disk drives the sleeve to slide in the fertilizer bin. During the sliding process of the sleeve, the baffle is driven to slide in the storage tank, thereby adjusting the available volume of the storage tank. The amount of fertilizer stored in the storage tank can be adjusted according to actual needs, and the actual volume of the storage tank will not be affected by the rotation of the rotating shaft.

[0019] The present invention utilizes a sleeve to drive the conical wheel to slide. When the amount of fertilizer required by the crop is large, the rotating knob drives the partition to expand the actual volume of the storage tank. The transmission belt cooperates with the position with a larger diameter of the conical wheel, so that the rotating rod drives the turntable to rotate faster, and the fertilizer between the two adjacent partitions can be thrown out faster. In the same time, more fertilizer can be spread into the soil to meet the needs of the crop. If the amount of fertilizer required by the crop is small, the fertilizer spread into the soil will be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The screw 9 is rotatably installed on the upper end of one of the connecting rods 6. The screw 9 is rotated and cooperates with the limit seat 10 through the screw 9, so that the screw 9 drives the connecting rod 6 and the first slide bar 5 and the second slide bar 46 to move up and down synchronously on the bracket 4. The first slide bar 5 drives the plow 7 to rise and fall, and the height of the plow 7 is adjusted to facilitate furrowing of different depths for different soils. At the same time, the elastic force of the spring 8 pushes one end of the plow 7 downward to maintain a good furrowing effect. When the plow 7 encounters a harder stone, one end of the plow 7 rotates upward to compress the spring 8, which improves the smoothness of the plow 7 in the furrowing process and reduces the collision damage of the plow 7.

[0033] A fertilizer bin 11 is fixedly mounted on the bracket 4, and a plurality of discharge chutes 12 are provided at the bottom of the fertilizer bin 11. A motor 26 is fixedly mounted on one side of the fertilizer bin 11. A rotating shaft 13 connected to the motor 26 is rotatably mounted in the fertilizer bin 11, and a plurality of storage troughs 14 are provided on the rotating shaft 13. The storage troughs 14 correspond one to one with the discharge troughs 12. A sleeve 15 is sleeved on the rotating shaft 13, and the sleeve 15 is horizontally slidably mounted in the fertilizer bin 11. A plurality of feed ports 16 and discharge ports 17 are respectively provided at the upper and lower ends of the sleeve 15. The feed ports 16 and the discharge ports 17 correspond one to one with the storage troughs 14, and each storage trough 14 is horizontally slidably mounted. Baffle 18, each baffle 18 is rotatably mounted on the inner wall of the sleeve 15, a threaded disc 21 is rotatably mounted on one end of the sleeve 15, a telescopic rod 23 is fixedly mounted on one side of the threaded disc 21, a knob 24 is fixedly mounted on one end of the telescopic rod 23, and the knob 24 is rotatably mounted on the fertilizer bin 11. A threaded groove 22 that cooperates with the threaded disc 21 is provided in the fertilizer bin 11. A plurality of limit strips 19 are fixedly mounted on the sleeve 15, and a plurality of guide grooves 20 for limiting the limit strips 19 are provided in the fertilizer bin 11. The guide grooves 20 correspond one to one with the limit strips 19. A plurality of collecting hoppers 37 are fixedly mounted on the lower end of the fertilizer bin 11. The collecting hoppers 37 corresponds to the discharge chute 12 one by one, and the rotating knob 24 drives the telescopic rod 23 to rotate synchronously with the threaded disk 21. The telescopic rod 23 is extended and retracted through the cooperation of the threaded disk 21 and the threaded groove 22. At the same time, the threaded disk 21 drives the sleeve 15 to slide in the fertilizer bin 11. The limit bar 19 is limited by the guide groove 20, so that the sleeve 15 slides horizontally in the fertilizer bin 11 without rotating. The positions of the feed port 16 and the discharge port 17 will not be deflected. During the sliding process of the sleeve 15, the baffle 18 will be driven to slide in the storage trough 14 and the available volume of the storage trough 14 will be adjusted. During the rotation process of the rotating shaft 13 driven by the motor 26, when the rotating shaft 1 After the storage trough 14 on 3 rotates to the bottom of the discharge trough 12, the fertilizer in the fertilizer bin 11 falls into the storage trough 14 through the discharge trough 12 and the feed port 16 on the sleeve 15. According to the adjustment of the position of the baffle 18 by the sleeve 15, the amount of fertilizer stored in the storage trough 14 can be adjusted according to actual needs. During the rotation of the rotating shaft 13, the baffle 18 will be driven to rotate synchronously. The actual volume of the storage trough 14 will not be affected by the rotation of the rotating shaft 13. When the storage trough 14 rotates to the bottom and is aligned with the discharge port 17 on the sleeve 15, the fertilizer in the storage trough 14 will move downward under gravity and enter the collecting hopper 37 through the discharge port 17.

[0034] The lower end of each collecting hopper 37 is connected to a discharge bin 38, and a discharge trough 40 is provided at the lower end of each discharge bin 38. A turntable 43 connected to the rotating shaft 13 is rotatably installed in each discharge bin 38, and a number of partitions 44 are fixedly installed on each turntable 43. The partitions 44 are distributed in a circle. A feeding bin 39 for extending the feeding time between adjacent partitions 44 is provided at the connection between each discharge bin 38 and the collecting hopper 37. A push rod 41 is rotatably installed at the connection between each feeding bin 39 and the collecting hopper 37. A guide rod 25 is fixedly installed at one end of the rotating shaft 13, and one end of the guide rod 25 is fixedly connected to the output end of the motor 26. A conical wheel 30 is installed on the guide rod 25 for transverse sliding. One end of the conical wheel 30 rotates with one end of the sleeve 15 A rotating rod 42 connected to the rotating shaft 13 is rotatably installed on the fertilizer bin 11, and each turntable 43 is fixedly installed on the rotating rod 42. A transmission wheel 31 is fixedly installed at one end of the rotating rod 42. A transmission belt 32 is installed between the transmission wheel 31 and the conical wheel 30. The length of the conical wheel 30 is the same as the length of the storage trough 14. A fixed seat 33 is fixedly installed on the fertilizer bin 11. Elastic rods 34 are fixedly installed on both sides of the fixed seat 33. Each elastic rod 34 is always in a compressed state, and a limiter 35 for limiting the transmission belt 32 is fixedly installed at one end of each elastic rod 34. Four rollers 36 are rotatably installed in the two limiters 35. The four rollers 36 are respectively located around the transmission belt 32; the fertilizer enters the collecting hopper 37 After the material is discharged, it is gradually put into the discharge bin 38 by the action of gravity. When the motor 26 is working, the guide rod 25 drives the rotating shaft 13 to rotate, and the guide rod 25 drives the conical wheel 30 to rotate synchronously. Since the conical wheel 30 is rotatably mounted on the sleeve 15, the sleeve 15 drives the baffle 18 to adjust the volume of the storage trough 14, which will also drive the conical wheel 30 to slide synchronously. Since the length of the conical wheel 30 is the same as the length of the storage trough 14, when the actual volume of the storage trough 14 is larger, the transmission belt 32 is matched with the position of the conical wheel 30 with a larger diameter; the smaller the actual volume of the storage trough 14, the transmission belt 32 is matched with the position of the conical wheel 30 with a smaller diameter; the transmission belt 32 is limited by the roller 36 inside the limiter 35, so that the transmission The belt 32 always maintains a vertical transmission state, the upper end of the transmission belt 32 does not move with the conical wheel 30, and the roller 36 does not affect the transmission of the transmission belt 32. Since the elastic rod 34 is always in a compressed state, it always pushes the two limit members 35 to move in opposite directions, so that the transmission belt 32 remains in a tensioned state and continues to transmit. The conical wheel 30 drives the transmission wheel 31 and the rotating rod 42 to rotate, and the rotating rod 42 drives the turntable 43 to rotate. The fertilizer in the collecting hopper 37 falls between the two adjacent partitions 44 on the turntable 43, and as the turntable 43 rotates, the fertilizer between the two adjacent partitions 44 is transported to the bottom of the discharge bin 38 and thrown out from the discharge trough 40 at the bottom of the discharge bin 38 into the furrow opened by the coulter 7 in the soil, so that the fertilizer is spread into the soil at different depths.When the amount of fertilizer required by the crop is large, the rotating knob 24 drives the baffle 18 to expand the actual volume of the storage tank 14, and the transmission belt 32 cooperates with the larger diameter position of the conical wheel 30, so that the rotating rod 42 drives the turntable 43 to rotate faster, and the fertilizer between the two adjacent partitions 44 can be thrown out faster. In the same time, more fertilizer is spread into the soil to meet the needs of the crop. If the amount of fertilizer required by the crop is small, the fertilizer spread into the soil will be reduced. At the same time, when the fertilizer falls into the discharge bin 38, a part of the fertilizer falls onto the push rod 41, and the push rod 41 rotates to push the excess fertilizer in the discharge bin 38 into the feeding bin 39; when the speed of the turntable 43 increases, The fertilizer may not fill the space between two adjacent partitions 44. The feeding bin 39 extends the feeding time between two adjacent partitions 44 to ensure that a sufficient amount of fertilizer is discharged from the discharge trough 40 each time. The fertilizer can be directly thrown into the soil without being transported through a pipeline. When conventional equipment is used to quantitatively spread fertilizer, the fertilizer usually needs to be transported through a pipeline before it falls into the soil. In the pipeline, the fertilizer will collide with the inner wall of the pipeline, changing the movement trajectory of the fertilizer and extending the transportation time of the fertilizer. As a result, different fertilizer particles will pass through the pipeline at different times, which can easily lead to uneven fertilizer distribution. However, the present device directly throws the fertilizer, and the amount of fertilizer thrown each time is sufficient and uniform.

[0035] A stirring shaft 28 is rotatably installed in the fertilizer bin 11), and a gear 27 is fixedly installed at one end of the stirring shaft 28. A gear 27 is rotatably installed on the guide rod 25, and the two gears 27 are meshed with each other. A plurality of spiral bars 29 for pushing the fertilizer to the discharge trough 12 are fixedly installed on the stirring shaft 28; the motor 26 drives the guide rod 25 and the gear 27 to rotate, and the meshing of the two gears 27 drives the stirring shaft 28 to rotate. During the rotation of the stirring shaft 28, the spiral bars 29 push the fertilizer on both sides of the discharge trough 12 to the discharge trough 12, ensuring that there is always enough fertilizer in the discharge trough 12. A plurality of leveling shovels 45 are fixedly installed on one side of the fertilizer bin 11. The leveling shovels 45 correspond to the discharge bin 38 one by one, and each leveling shovel 45 is arranged in a V shape. The leveling shovel 45 backfills the soil produced by the furrowing of the coulter 7, covers the fertilizer, reduces the volatilization of the fertilizer, enables the soil to fully absorb the fertilizer, and improves the fertility of the soil.

[0036] Specifically, first rotate the screw 9 so that the screw 9 drives the connecting rod 6 and the first slide bar 5 and the second slide bar 46 to move up and down synchronously on the bracket 4, and the first slide bar 5 drives the plow blade 7 to rise and fall, and adjusts the height of the plow blade 7 to facilitate trenching of different depths in different soils. Then, rotate the knob 24 to drive the telescopic rod 23 to rotate synchronously with the threaded disk 21. Through the cooperation of the threaded disk 21 and the threaded groove 22, the telescopic rod 23 is extended and retracted. At the same time, the threaded disk 21 drives the sleeve 15 to slide in the fertilizer bin 11, and the limit bar 19 is limited by the guide groove 20, so that the sleeve 15 slides horizontally in the fertilizer bin 11 without rotating, and the positions of the feed port 16 and the discharge port 17 will not be deflected. The sleeve 15 slides through During the process, the baffle 18 is driven to slide in the storage trough 14, the available volume of the storage trough 14 is adjusted, and then the engine 2 is started to drive the two traveling wheels 3 to rotate, driving the frame 1 to move. At the same time, the person holds the moving direction of the frame 1 and starts the motor 26. During the rotation of the motor 26, when the storage trough 14 on the rotating shaft 13 rotates to the bottom of the discharge trough 12, the fertilizer in the fertilizer bin 11 passes through the discharge trough 12 and the feeding port 16 on the sleeve 15 and falls into the storage trough 14. According to the adjustment of the position of the baffle 18 by the sleeve 15, the amount of fertilizer stored in the storage trough 14 can be adjusted according to actual needs. When the storage trough 14 rotates to the bottom and is aligned with the discharge port 17 on the sleeve 15, the storage trough The fertilizer in 14 will move downward due to gravity and enter the collecting hopper 37 through the discharge port 17. After entering the collecting hopper 37, the fertilizer will gradually enter the discharge bin 38 under the action of gravity. When the motor 26 is working, the guide rod 25 drives the rotating shaft 13 to rotate. During the rotation of the guide rod 25, the conical wheel 30 is driven to rotate synchronously. Since the conical wheel 30 is rotatably mounted on the sleeve 15, the sleeve 15 drives the baffle 18 to adjust the volume of the storage tank 14, and also drives the conical wheel 30 to slide synchronously. Since the length of the conical wheel 30 is the same as the length of the storage tank 14, when the actual volume of the storage tank 14 is larger, the transmission belt 32 cooperates with the position with the larger diameter of the conical wheel 30, and the storage tank 14 The smaller the actual volume, the smaller the transmission belt 32 will be matched with the position with the smaller diameter of the conical wheel 30. The transmission belt 32 is limited by the roller 36 in the limiter 35, so that the transmission belt 32 always maintains a vertical transmission state, and the upper end of the transmission belt 32 does not move with the conical wheel 30. Through the transmission of the transmission belt 32, the conical wheel 30 drives the transmission wheel 31 and the rotating rod 42 to rotate, and the rotating rod 42 drives the turntable 43 to rotate. The fertilizer in the collecting hopper 37 falls between the two adjacent partitions 44 on the turntable 43, and as the turntable 43 rotates, the fertilizer between the two adjacent partitions 44 is transported to the bottom of the discharge bin 38, and is thrown out from the discharge trough 40 at the bottom of the discharge bin 38 into the furrow opened by the coulter 7 in the soil;When the amount of fertilizer required by the crop is large, the rotating knob 24 drives the baffle 18 to expand the actual volume of the storage tank 14, and the transmission belt 32 cooperates with the larger diameter position of the conical wheel 30, so that the rotating rod 42 drives the turntable 43 to rotate faster, and the fertilizer between the two adjacent partitions 44 can be thrown out faster, and more fertilizer can be spread into the soil in the same time to meet the needs of the crop; if the amount of fertilizer required by the crop is small, the fertilizer spread into the soil will be reduced. At the same time, when the fertilizer falls into the discharge bin 38, a part of the fertilizer falls onto the push rod 41, and the push rod 41 rotates to push the excess fertilizer in the discharge bin 38 out. Fertilizer is pushed into the feeding bin 39, which extends the feeding time between adjacent partitions 44 to ensure that a sufficient amount of fertilizer is discharged from the discharge chute 40 each time. When the motor 26 is in operation, it drives the guide rod 25 and gear 27 to rotate. The meshing of the two gears 27 drives the stirring shaft 28 to rotate. During the rotation of the stirring shaft 28, the spiral strips 29 push the fertilizer on both sides of the discharge chute 12 into the discharge chute 12, ensuring that the discharge chute 12 always has sufficient fertilizer. Finally, the leveling shovel 45 backfills the soil created by the coulter 7 and covers the fertilizer, reducing fertilizer volatilization and ensuring that the soil fully absorbs the fertilizer.
