Description

Technical Field

[0001] The present invention relates to the technical field of rice - rapeseed rotation, and particularly relates to a fertilizing device for rice - rapeseed rotation and its working method. Background Art

[0002] Rice - rapeseed rotation refers to a planting method in which one to two seasons of rice are planted in the same field, and immediately after harvesting, one season of rapeseed is planted. The rice - rapeseed rotation mode is mainly based on the efficient utilization of land resources and the balance of the agricultural ecosystem. In order to make full use of these land resources, improve soil structure, reduce the occurrence of pests and diseases, and increase farmers' economic income, the rice - rapeseed rotation mode came into being. In addition, this mode helps to achieve the sustainable development of agriculture. By rotating different crops, it is possible to avoid soil nutrient imbalance and the accumulation of pests and diseases.

[0003] Deficiencies in the prior art: Since the growth conditions and fertilization requirements of rice and rapeseed are different, when switching between the two crops, it is necessary to adjust the fertilization amount according to the planted crop. However, when the existing fertilizing device switches between the two crops, it cannot adjust the fertilization amount and height according to the crop replacement, which will lead to problems such as uneven fertilization and inaccurate fertilization position due to different growth conditions and fertilization requirements, with poor adaptability and greatly reducing the fertilization efficiency of the fertilizing device. Summary of the Invention

[0004] The problem to be solved by the present invention is that when the existing fertilizing device switches between two crops, it cannot adjust the fertilization amount and height, resulting in uneven fertilization and inaccurate fertilization position, greatly reducing the fertilization efficiency.

[0005] To solve the above - mentioned technical problems, the present invention provides a fertilizing device for rice - rapeseed rotation, including a frame and support plates fixedly connected to both sides of its top. A chute is provided in the middle of the support plates. An fixing plate is arranged between the two support plates. Adjusting components for adjusting the height of the fixing plate are arranged in the middle of both support plates. A fertilizing component for fertilizing is arranged on one side of the bottom end of the fixing plate. A fertilizer discharge port is provided on the fixing plate. A conveying bin is fixedly installed on the top end of the fixing plate. A spiral conveying blade is arranged in the middle of the inner cavity of the conveying bin;

[0006] The fertilizing component includes a connecting plate fixedly connected to one side of the bottom end of the fixing plate. One end of the connecting plate is fixedly connected to a first deflector plate, and the other end of the connecting plate is movably connected to a second deflector plate.

[0007] Preferably, the first deflector plate and the second deflector plate are respectively located on both sides of the bottom end of the fertilizer discharge port. One side of the inner cavity of the fertilizer discharge port is inclined, and the fertilizer discharge port is connected and communicated with the first deflector plate and the second deflector plate.

[0008] Preferably, one end of the first flow guide plate is fixedly connected with a first connecting piece, one end of the second flow guide plate is fixedly connected with a second connecting piece, the second connecting piece is located above the first connecting piece, and the first connecting piece and the second connecting piece are rotatably connected.

[0009] Preferably, a first motor is fixedly installed on one side of the bottom end of the fixed plate close to the fertilizer discharging port, and the output end of the first motor is fixedly connected with the top end of the second connecting piece.

[0010] Preferably, the adjusting assembly includes an adjusting rod movably connected to the inner cavity of the sliding groove. One end of the adjusting rod is fixedly connected with a rack. One end of the support plate is fixedly connected with a mounting plate, and a gear is rotatably connected to the mounting plate.

[0011] Preferably, the two adjusting rods are respectively fixedly connected to both ends of the fixed plate. A second motor is fixedly installed on one side of the top end of the vehicle frame, and the output end of the second motor is fixedly connected with the gear. The gear is meshed with the rack.

[0012] Preferably, baffles are fixedly connected to both sides of the bottom end of the vehicle frame. Two walking wheels are arranged at one end of each of the two baffles. A driving device for driving the walking wheels to rotate is arranged at the other end of the baffle. A handlebar is fixedly connected to one side of the top end of the vehicle frame.

[0013] Preferably, a feeding hopper is fixedly communicated with one side of the top end of the conveying bin. A third motor is fixedly installed at one end of the conveying bin far from the fertilizer discharging port. The output end of the third motor penetrates through the conveying bin and is fixedly connected with one end of the spiral conveying blade. The conveying bin is communicated with the fertilizer discharging port.

[0014] The present invention also provides a working method for a fertilizing device for rice and rapeseed rotation, including the following steps:

[0015] Step 1: First, start the second motor. Drive the gear to rotate through the output end of the second motor, drive the rack engaged on the surface to move up and down, so that when the rack moves, drive the adjusting rod to slide up and down in the inner cavity of the sliding groove, drive the fixed plate to move up and down through the up and down sliding of the adjusting rod, adjust the distance between the fixed plate and the surface of the planting field, and at the same time adjust the distance between the fertilizer applying assembly at the bottom end of the fixed plate and the planting field. Through the adjusting assembly, the height of the fertilizer applying assembly can be adjusted according to the specific situation of the planted crops;

[0016] Step 2: Then start the first motor. Control the second connecting piece to rotate at the top of the first connecting piece through the output end of the first motor, drive the second guide plate to rotate to one side, adjust the distance between the first guide plate and the second guide plate, and control the fertilization speed by adjusting the opening size between the first guide plate and the second guide plate. When the opening increases, the fertilization speed increases; when the opening decreases, the fertilization speed decreases.

[0017] Step 3: After the equipment height and the fertilizer outflow amount are adjusted, select the corresponding fertilizer and add it to the inner cavity of the feeding hopper. The fertilizer then drops into the inner cavity of the conveying bin through the feeding hopper. Then start the third motor. Control the spiral conveying blade to rotate through the output end of the third motor. As the rotating spiral conveying blade conveys the fertilizer in the inner cavity of the conveying bin to the fertilizer discharging port, adjust the rotating speed of the spiral conveying blade by controlling the rotating speed of the third motor. The greater the rotating speed, the greater the conveying speed; the smaller the rotating speed, the smaller the conveying speed.

[0018] Step 4: After the equipment is adjusted, start the driving device. Drive the traveling wheels to rotate through the driving device, and drive the fertilizing equipment to move in the planting field through the traveling wheels. As the equipment moves, the fertilizer continuously flows out, enabling the equipment to achieve precise fertilization. At the same time, the traveling direction of the fertilizing equipment can be controlled through the handlebar to complete the fertilization operation.

[0019] The technical effects and advantages of the present invention:

[0020] 1. The present invention adjusts the outflow amount of the fertilizer by providing a fertilizing component. During the use of the equipment, according to the growth conditions and fertilization requirements of the planted crops, adjust the opening size between the first guide plate and the second guide plate. Drive the second connecting piece to rotate at the top of the first connecting piece through the first motor, so that the second connecting piece drives the second guide plate to rotate to one side and gradually separates from the first guide plate. By adjusting the opening size between the first guide plate and the second guide plate, change the outflow amount of the fertilizer, thereby controlling the fertilization speed. When the opening increases, the fertilization speed increases; when the opening decreases, the fertilization speed decreases. This enables the equipment to adjust the outflow amount of the fertilizer according to the fertilization requirements of the planted crops, so that the equipment can adapt to the needs of different crops.

[0021] 2. The present invention adjusts the height of the fertilizing component by providing an adjusting component. Since the growth conditions of different planted crops are different, the growth heights of the planted crops at different times are also different. When in use, start the second motor. The second motor makes the gear rotate, drives the rack meshed on the surface to move up and down, and makes the adjusting rod move up and down in the inner cavity of the sliding groove. Since the adjusting rod is fixed on both sides of the fixing plate, the distance between the fixing plate and the surface of the planting field is adjusted, and at the same time, the distance between the fertilizing component at the bottom of the fixing plate and the planting field is adjusted. According to the specific growth conditions of the planted crops, adjust the height of the fertilizing component through the adjusting component to avoid too high or too low fertilization height, which affects the fertilization effect and accuracy.

[0022] 3. The present invention is provided with a spiral conveying blade for conveying fertilizers. The output end of the third motor controls the rotation of the spiral conveying blade. As the rotating spiral conveying blade conveys the fertilizers in the inner cavity of the conveying bin to the fertilizer discharging port. Since the conveying speed of the fertilizers also affects the outflow rate of the fertilizers, the rotation speed of the third motor is controlled to adjust the rotation speed of the spiral conveying blade, and the rotation speed is increased or decreased as needed, so as to change the conveying speed of the fertilizers. One side of the inner cavity of the fertilizer discharging port is set to be inclined, so that the fertilizers can fall into the fertilizing assembly more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0030] The present invention provides a fertilizing device for rice-rape rotation, as Figure 1 - Figure 6As shown, it includes a frame 1 and support plates 2 fixedly connected to both sides of its top. A chute 9 is provided in the middle of the support plates 2. A fixing plate 3 is arranged between the two support plates 2. Adjusting components 4 for adjusting the height of the fixing plate 3 are arranged in the middle of both support plates 2. A fertilizing component 5 for fertilizing is arranged on one side of the bottom end of the fixing plate 3. A fertilizer discharge port 6 is provided on the fixing plate 3. A conveying bin 7 is fixedly installed at the top end of the fixing plate 3. A spiral conveying blade 8 is arranged in the middle of the inner cavity of the conveying bin 7.

[0031] Further, as Figure 1 , Figure 2 and Figure 3 shown, the fertilizing component 5 includes a connecting plate 51 fixedly connected to one side of the bottom end of the fixing plate 3. One end of the connecting plate 51 is fixedly connected to a first guide plate 52, and the other end of the connecting plate 51 is movably connected to a second guide plate 53.

[0032] Further, as Figure 2 and Figure 4 shown, the first guide plate 52 and the second guide plate 53 are respectively located on both sides of the bottom end of the fertilizer discharge port 6. One side of the inner cavity of the fertilizer discharge port 6 is inclined. The fertilizer discharge port 6 is connected and communicated with the first guide plate 52 and the second guide plate 53. The inclined surface in the inner cavity of the fertilizer discharge port 6 enables the fertilizer to flow more smoothly onto the first guide plate 52 and the second guide plate 53.

[0033] Further, as Figure 3 and Figure 4 shown, one end of the first guide plate 52 is fixedly connected to a first connecting piece 54, and one end of the second guide plate 53 is fixedly connected to a second connecting piece 55. The second connecting piece 55 is located above the first connecting piece 54, and the first connecting piece 54 and the second connecting piece 55 are rotatably connected.

[0034] Further, as Figure 3 and Figure 4 shown, a first motor 56 is fixedly installed on one side of the bottom end of the fixing plate 3 close to the fertilizer discharge port 6. The output end of the first motor 56 is fixedly connected to the top end of the second connecting piece 55. Before the equipment performs the fertilizing operation, first start the first motor 56, and control the second connecting piece 55 to rotate on the top end of the first connecting piece 54 through the output end of the first motor 56. Since the first guide plate 52 is fixedly connected to the connecting plate 51, the second connecting piece 55 will drive the second guide plate 53 to rotate to one side. As the second guide plate 53 rotates, the opening size between the first guide plate 52 and the second guide plate 53 is adjusted to change the outflow amount of the fertilizer, thereby controlling the fertilizing speed. When the opening increases, the fertilizing speed increases; when the opening decreases, the fertilizing speed decreases. It is adjusted according to the fertilizing requirements of crop plants, effectively increasing the applicability of the fertilizing equipment to meet the fertilizing requirements of different crops.

[0035] Further, asFigure 1 and Figure 5 As shown in Figure 5 , the adjusting assembly 4 includes an adjusting rod 41 movably connected to the inner cavity of the sliding groove 9. One end of the adjusting rod 41 is fixedly connected with a rack 42. One end of the support plate 2 is fixedly connected with a mounting plate 43, and a gear 44 is rotatably connected to the mounting plate 43.

[0036] Further, as Figure 5 and Figure 6 shown in Figure 6 , the two adjusting rods 41 are respectively fixedly connected to both ends of the fixing plate 3. A second motor 45 is fixedly installed on one side of the top end of the vehicle frame 1. The output end of the second motor 45 is fixedly connected with the gear 44. The gear 44 is meshed with the rack 42. Since the growth conditions of different plants are different, the growth heights are also different. According to the specific growth conditions of the planted plants, the distance between the fertilizing assembly 5 and the planting field is adjusted. The second motor 45 is started, and the gear 44 is driven to rotate through the output end of the second motor 45, driving the rack 42 engaged on the surface to move up and down. When the rack 42 moves, it drives the adjusting rod 41 to slide up and down in the inner cavity of the sliding groove 9. Since the adjusting rod 41 is fixedly connected to both sides of the fixing plate 3, according to the specific growth conditions of the planted plants, the height of the adjusting rod 41 is adjusted, so that the fixing plate 3 moves up and down to adjust the distance between the fixing plate 3 and the surface of the planting field, and at the same time, the distance between the fertilizing assembly 5 at the bottom end of the fixing plate 3 and the planting field is adjusted. Since the growth conditions of different plants are different, the growth heights of the planted plants at different times are also different. Through the adjusting assembly 4, the height of the fertilizing assembly 5 can be adjusted according to the specific conditions of the planted plants, avoiding the influence of too high or too low fertilizing height on the fertilizing effect and accuracy.

[0037] Further, as Figure 1 and Figure 2 shown in Figure 2 , baffles 10 are fixedly connected to both sides of the bottom end of the vehicle frame 1. Two walking wheels 11 are arranged at one end of each of the two baffles 10, and a driving device 12 for driving the walking wheels 11 to rotate is arranged at the other end of the baffle 10. A handlebar 13 is fixedly connected to one side of the top end of the vehicle frame 1. When using the fertilizing device, the driving device 12 is used to drive the walking wheels 11 to rotate, driving the device to move. At the same time, the operator can control the driving direction of the device through the handlebar 13.

[0038] Further, as Figure 1 and Figure 2As shown in the figure, a feeding hopper 14 is fixedly connected to one side of the top end of the conveying bin 7. A third motor 15 is fixedly installed at one end of the conveying bin 7 away from the fertilizer discharging port 6. The output end of the third motor 15 penetrates through the conveying bin 7 and is fixedly connected to one end of the spiral conveying blade 8. The conveying bin 7 is communicated with the fertilizer discharging port 6. The prepared fertilizer is added into the inner cavity of the feeding hopper 14, and the fertilizer then falls into the inner cavity of the conveying bin 7 through the feeding hopper 14. Then, the third motor 15 is started, and the spiral conveying blade 8 is controlled to rotate through the output end of the third motor 15. As the rotating spiral conveying blade 8 conveys the fertilizer in the inner cavity of the conveying bin 7 to the fertilizer discharging port 6, one side of the inner cavity of the fertilizer discharging port 6 is inclined, so that the fertilizer can fall into the fertilizing assembly 5 more smoothly. During the use process, the conveying speed of the fertilizer can be adjusted according to the growth requirements of the planted crops. By controlling the rotating speed of the third motor 15, the rotating speed of the spiral conveying blade 8 is adjusted, and the rotating speed is increased or decreased as needed, so as to change the conveying speed of the fertilizer, effectively improving the practicability of the equipment.

[0039] The present invention also provides a working method for a fertilizing device for rice and rapeseed rotation, as Figure 1 - Figure 6 shown, including the following steps:

[0040] Step 1: First, start the second motor 45. Drive the gear 44 to rotate through the output end of the second motor 45, drive the rack 42 engaged on the surface to move up and down. When the rack 42 moves, drive the adjusting rod 41 to slide up and down in the inner cavity of the sliding groove 9. According to the specific growth conditions of the planted crops, adjust the height of the adjusting rod 41, so that the fixing plate 3 moves up and down, to adjust the distance between the fixing plate 3 and the surface of the planting field, and at the same time adjust the distance between the fertilizing assembly 5 at the bottom end of the fixing plate 3 and the planting field. Since the growth conditions of different planted crops are different, the growth heights of the planted crops at different times are also different. Through the adjusting assembly 4, the height of the fertilizing assembly 5 can be adjusted according to the specific conditions of the planted crops, avoiding the fertilizing height being too high or too low, which affects the fertilizing effect and accuracy;

[0041] Step 2: Then, start the first motor 56. Control the second connecting member 55 to rotate at the top end of the first connecting member 54 through the output end of the first motor 56, drive the second guide plate 53 to rotate to one side, and adjust the distance between the first guide plate 52 and the second guide plate 53. By adjusting the opening size between the first guide plate 52 and the second guide plate 53, change the outflow amount of the fertilizer, so as to control the fertilizing speed. When the opening increases, the fertilizing speed increases. When the opening decreases, the fertilizing speed decreases, effectively increasing the applicability of the fertilizing device to meet the fertilizing requirements of different crops;

[0042] Step 3: After the adjustment of the equipment height and the fertilizer outflow volume is completed, select the corresponding fertilizer and add it to the inner cavity of the feeding hopper 14. The fertilizer then drops into the inner cavity of the conveying bin 7 through the feeding hopper 14. Then, start the third motor 15, and control the rotation of the spiral conveying blade 8 through the output end of the third motor 15. As the rotating spiral conveying blade 8 conveys the fertilizer in the inner cavity of the conveying bin 7 to the fertilizer discharging port 6, by controlling the rotation speed of the third motor 15, the rotation speed of the spiral conveying blade 8 is adjusted, and the rotation speed is increased or decreased as needed, so as to change the conveying speed of the fertilizer. One side of the inner cavity of the fertilizer discharging port 6 is set to be inclined, so that the fertilizer can fall into the fertilizing assembly 5 more smoothly;

[0043] Step 4: After the equipment adjustment is completed, start the driving device 12, drive the traveling wheels 11 to rotate through the driving device 12, and drive the fertilizing equipment to move in the planting field through the traveling wheels 11. The fertilizing assembly 5 is located above the fertilizing position. As the equipment moves, fertilizer is continuously scattered to the designated position to complete the fertilizing operation of the planting field, realizing precise fertilization. At the same time, the traveling direction of the fertilizing equipment can be controlled through the handlebar 13, making the equipment operation more convenient and fast, and effectively improving the working efficiency of the equipment.
