Description

Technical Field

[0001] The utility model relates to the technical field of soil improvement, and more specifically, to agricultural equipment used for agricultural soil improvement. Background Art

[0002] Agricultural soil is the basis for the growth of crops. Its quality and health are directly related to the yield and quality of crops. However, due to long-term unreasonable farming, excessive use of fertilizers and pesticides, and changes in the natural environment, the soil quality in many areas has gradually declined, and problems such as soil compaction, salinization, and nutrient imbalance have emerged. These problems not only restrict the normal growth of crops, but also affect the quality and safety of agricultural products, and even cause damage to the ecological environment. Physical improvement mainly improves the soil environment by changing the physical properties of the soil. For example, deep plowing, loosening the soil, and breaking up the soil compaction. Chemical improvement mainly improves the chemical properties of the soil by adding chemical substances to the soil. For example, for acidic soils, alkaline substances such as lime can be added to adjust the pH of the soil; for soils with insufficient nutrients, nutrients such as fertilizers and organic fertilizers can be added to improve the fertility of the soil; for soils with severe salinization, improvers such as gypsum can be added to reduce the salt content of the soil. In the prior art, physical and chemical methods are generally used together to improve the soil. While the machine is turning the soil, fertilizer is sprinkled into the soil to improve the properties of the soil. When the existing device is working, it is unable to make the most suitable improvement according to the actual situation of the soil. A large amount of fertilizer is required for poor soil, while only a small amount of fertilizer is required for fertile soil. If too much fertilizer is applied, it will cause waste, excessive nutrients in the soil, damage to the environment, etc. Too little fertilizer will lead to insufficient soil improvement, so it needs to be improved and optimized.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides an agricultural equipment for improving soil in agriculture, including a vehicle body 1, a storage hopper 2 is fixedly installed on the right side of the vehicle body 1, a feeding roller 3 is rotatably installed at the bottom of the storage hopper 2, a rotating rod 4 is fixedly installed on the middle of the feeding roller 3, the rotating rod 4 passes through the feeding roller 3 and the storage hopper 2, a pulley 5 is fixedly sleeved on the front of the outer surface of the rotating rod 4, a belt 6 is fixedly sleeved on the outer surface of the pulley 5, a pulley 2 7 is fixedly sleeved on the inner wall of the bottom of the belt 6, a fixing rod 9 is fixedly installed on the middle of the pulley 2 7, a large gear 8 is fixedly installed on the front of the pulley 2 7, the fixing rod 9 passes through the pulley 2 7 and the large gear 8, a fixing bar 10 is movably sleeved on the front of the outer surface of the fixing rod 9, the fixing bar 10 is fixedly installed on the right side of the storage hopper 2, and three speed regulating gears 14 are rotatably installed on the left side of the large gear 8, and the three speed regulating gears 14 are respectively meshed with the large gear 8.

[0021] The staff starts the hydraulic cylinder 13, and the output shaft of the hydraulic cylinder 13 drives the three speed regulating gears 14 to move forward and backward. The number of teeth of the three speed regulating gears 14 is different. The three speed regulating gears 14 are respectively meshed with the large gear 8 to drive the large gear 8 to rotate, and the large gear 8 drives the pulley 2 7 to rotate. The pulley 2 7 drives the pulley 1 5 to rotate through the belt 6, and the pulley 1 5 drives the feeding roller 3 to rotate at the bottom of the storage hopper 2. When the fertilizer is inside the storage hopper 2, the feeding roller 3 rotates, and the fertilizer is transported to the ground from the feeding square tube 11 by the grooves on the surface of the feeding roller 3. Since the number of teeth of the three speed regulating gears 14 is different, the number of teeth increases from front to back. When the three speed regulating gears 14 are respectively meshed with the large gear 8 from front to back, the large gear 8 drives the feeding roller 3 to rotate faster and faster, thereby controlling the discharge speed.

[0022] By starting the hydraulic cylinder 13, the output shaft of the hydraulic cylinder 13 is retracted and the three speed regulating gears 14 are respectively meshed with the large gear 8, and the large gear 8 drives the pulley 2 7 to rotate, and the pulley 2 7 drives the pulley 1 5 to rotate through the belt 6, and the pulley 1 5 drives the feeding roller 3 to rotate. By controlling the retraction of the output shaft of the hydraulic cylinder 13, the speed of the feeding roller 3 is adjustable, so that different feeding speeds of the fertilizer can be controlled. Compared with the traditional device, the retraction of the output shaft of the hydraulic cylinder 13 can accurately control the degree of meshing between the speed regulating gear 14 and the large gear 8, so as to realize the precise control of the speed of the feeding roller 3. This precise control ability makes the fertilizer feeding speed fine-tuned according to actual needs, fully contacting with the soil, ensuring the accuracy and uniformity of fertilization, and by accurately controlling the fertilizer feeding speed, it is possible to avoid waste of resources and environmental pollution caused by excessive fertilization, and the soil can be accurately improved according to needs.

[0023] Among them, two connecting blocks 15 are fixedly installed on the right side of the vehicle body 1, and hydraulic cylinders 16 are hinged in the middle of the right side of the two connecting blocks 15. A hinged rod 22 is rotatably installed in the middle of the right side of the vehicle body 1, and the hinged rod 22 penetrates the vehicle body 1 at both ends. Leveling frames 21 are movably sleeved at both ends of the outer surface of the hinged rod 22, and a loosening rake 23 is fixedly installed on the right bottom of the leveling frame 21. A connecting block 20 is rotatably installed inside the leveling frame 21, and the connecting block 20 penetrates the leveling frame 21 at both ends. The output shafts of the two hydraulic cylinders 16 are hingedly installed at both ends of the outer surface of the connecting block 20.

[0024] The staff starts the two hydraulic cylinders 216, and the output shafts of the two hydraulic cylinders 216 extend and retract to drive the connecting block 20 to rise and fall, and the rising and falling of the connecting block 20 drives the leveling frame 21 to rise and fall, and the leveling frame 21 is sleeved on the outer surface of the hinged rod 22, so that the leveling frame 21 rotates around the hinged rod 22, and a loosening rake 23 is fixedly installed on the right bottom of the leveling frame 21. The lifting of the leveling frame 21 drives the loosening rake 23 to rise and fall. When the vehicle body 1 is working, the output shafts of the two hydraulic cylinders 216 extend, and the leveling frame 21 flips downward, so that the right side of the leveling frame 21 contacts the ground, driving the loosening rake 23 to contact the ground, so that the loosened soil is fully mixed with the fertilizer under the turning of the loosening rake 23, and the ground is leveled through the right bottom of the leveling frame 21, so that the fertilizer is fully in contact with the soil.

[0025] By starting the two hydraulic cylinders 16, the output shafts of the two hydraulic cylinders 16 drive the leveling frame 21 to flip. When the device is working, the right bottom of the leveling frame 21 is driven by the output shaft of the hydraulic cylinder 16, so that the right bottom of the leveling frame 21 contacts the soil, driving the loosening harrow 23 to contact the soil, so that the fertilizer is fully mixed with the soil. Through the leveling of the leveling frame 21, the soil and fertilizer are mixed more fully. Compared with the traditional device, the flipping angle of the leveling frame 21 is accurately controlled by the hydraulic cylinder 16, which can ensure that the loosening harrow 23 contacts the soil with appropriate force and depth, and effectively mixes the fertilizer with the soil. This precise control ensures the uniformity of fertilizer distribution, is beneficial to the balanced absorption of nutrients by crops, and can adapt to different soil types and fertilization requirements. By adjusting the output of the hydraulic cylinder 16, it can adapt to soils of different hardness and humidity, ensuring that the loosening harrow 23 can effectively contact the soil and mix the fertilizer.

[0026] Among them, a hollow tube 17 is fixedly installed on the right side of the vehicle body 1, and a hinged rod 18 is rotatably installed inside the hollow tube 17. Rotating frames 19 are fixedly sleeved on both ends of the outer surface of the hinged rod 18. The rotating frame 19 is sleeved on the outer surface of the connecting block 20. A protective cover 24 is fixedly installed on the bottom of the rotating frame 19. Baffles 25 are fixedly installed on the front and back of the protective cover 24. A rotating rod 28 is rotatably installed on the bottom of the protective cover 24. The rotating rod 28 penetrates the baffle 25, and a plurality of rotating claws 27 are fixedly installed on the outer surface of the rotating rod 28.

[0027] By starting the motor 29, the output shaft of the motor 29 drives the pinion 1 30 to rotate, the pinion 1 30 drives the pinion 2 31 to rotate, the pinion 2 31 drives the rotating rod 28 to rotate, the rotating rod 28 drives the rotating claw 27 to rotate, and the two hydraulic cylinders 2 16 are started at the same time, and the output shafts of the two hydraulic cylinders 2 16 drive the rotating frame 19 to rise and fall, so that the rotating claw 27 contacts with the soil, and the rotating claw 27 rotates and turns the soil. When the fertilizer falls from the feeding square tube 11, the soil is turned by the rotation of the rotating claw 27, so that the fertilizer is fully mixed with the soil. The rotation and turning of the rotating claw 27 is not only fast, but also can ensure that the fertilizer is evenly distributed in the soil. Compared with the traditional sowing method, this system can avoid local accumulation of fertilizer in the soil, ensure that the fertilizer is fully absorbed by the soil, and improve the utilization rate of the fertilizer. By starting the two hydraulic cylinders 2 16, the lifting and lowering of the rotating frame 19 can be accurately controlled, so as to adjust the contact depth of the rotating claw 27 with the soil. This depth adjustability enables the system to adapt to the needs of different soil types and depths, and ensure that the fertilizer and soil are mixed at the optimal depth.

[0028] Among them, a fixed block 12 is fixedly installed on the right side of the vehicle body 1, a hydraulic cylinder 13 is fixedly installed on the front of the fixed block 12, three speed regulating gears 14 are fixedly sleeved on the outer surface of the output shaft of the hydraulic cylinder 13, and a feeding square pipe 11 is fixedly installed at the bottom of the storage hopper 2.

[0029] By starting the hydraulic cylinder 13, the output shaft of the hydraulic cylinder 13 is extended and retracted to drive the three speed regulating gears 14 to mesh with the large gear 8 respectively. Since the number of teeth of the three speed regulating gears 14 increases from front to back, the output shaft of the hydraulic cylinder 13 is controlled to extend and retract so that the three speed regulating gears 14 are respectively meshed with the large gear 8, so that the rotation speed of the feeding roller 3 can be controlled, thereby accurately controlling the amount of fertilizer falling from the feeding square tube 11. This design can adjust the different degrees of improvement required according to the different properties of different soils. By accurately controlling the amount of fertilizer added, the system avoids excessive fertilizer addition and waste, which not only reduces costs but also reduces pollution to the environment. At the same time, due to the use of hydraulic drive, compared with traditional mechanical transmission methods, the system has lower energy consumption and is more energy-saving and environmentally friendly.

[0030] Among them, a motor protection shell 26 is fixedly installed on the front side of the baffle 25 located on the front side, and a motor 29 is fixedly installed on the inner back side of the motor protection shell 26. A pinion 30 is fixedly sleeved on the output shaft of the motor 29, and a pinion 2 31 is rotatably installed on the bottom of the pinion 1 30 and the pinion 2 31 is meshed with the pinion 1 30. The rotating rod 2 28 passes through the pinion 2 31 and the pinion 2 31 is fixedly sleeved on the outer surface of the rotating rod 28.

[0031] By starting the motor 29, the output shaft of the motor 29 drives the pinion 1 30 to rotate, the pinion 1 30 meshes with the pinion 2 31, drives the pinion 2 31 to rotate, the pinion 2 31 drives the rotating rod 28 to rotate, and the rotating rod 28 drives the rotating claw 27 to rotate. This mechanism of turning the soil by driving the rotating claw 27 through the motor 29 has the advantages of efficient power transmission, rapid soil turning, simple operation, high reliability, flexible adjustment, energy saving and environmental protection, etc. These advantages make the mechanism have important application value in agricultural production.

[0032] The number of teeth of the three speed regulating gears 14 is different from each other, and the number of teeth of the three speed regulating gears 14 increases from the front to the back.

[0033] By starting the hydraulic cylinder 13, the output shaft of the hydraulic cylinder 13 drives the speed regulating gear 14 to move forward and backward, thereby controlling the speed regulating gear 14 with different numbers of teeth to mesh with the large gear 8, thereby controlling the rotation speed of the feeding roller 3. When the feeding roller 3 rotates slowly, less fertilizer falls, and when the feeding roller 3 rotates quickly, more fertilizer falls. Since the speed regulating gear 14 has different numbers of teeth, the system can adapt to different soil properties and crop requirements, and can accurately control the amount of fertilizer added by selecting a suitable gear combination. By accurately controlling the amount of fertilizer added, the system avoids waste and excessive use of fertilizers, thereby reducing agricultural production costs.

[0034] The working principle and use process of this utility model:

[0035] The staff starts the hydraulic cylinder 13, and the output shaft of the hydraulic cylinder 13 drives the three speed regulating gears 14 to move forward and backward. The number of teeth of the three speed regulating gears 14 is different. The three speed regulating gears 14 are respectively meshed with the large gear 8 to drive the large gear 8 to rotate, and the large gear 8 drives the pulley 2 7 to rotate. The pulley 2 7 drives the pulley 1 5 to rotate through the belt 6, and the pulley 1 5 drives the feeding roller 3 to rotate at the bottom of the storage hopper 2. When the fertilizer is inside the storage hopper 2, the feeding roller 3 rotates, and the fertilizer is transported to the ground from the feeding square tube 11 by the grooves on the surface of the feeding roller 3. Since the number of teeth of the three speed regulating gears 14 is different, the number of teeth increases from front to back. When the three speed regulating gears 14 are respectively meshed with the large gear 8 from front to back, the large gear 8 drives the feeding roller 3 to rotate faster and faster, thereby controlling the discharge speed.

[0036] The staff starts the two hydraulic cylinders 216, and the output shafts of the two hydraulic cylinders 216 extend and retract to drive the connecting block 20 to rise and fall, and the rising and falling of the connecting block 20 drives the leveling frame 21 to rise and fall, and the leveling frame 21 is sleeved on the outer surface of the hinged rod 22, so that the leveling frame 21 rotates around the hinged rod 22, and a loosening rake 23 is fixedly installed on the right bottom of the leveling frame 21. The lifting of the leveling frame 21 drives the loosening rake 23 to rise and fall. When the vehicle body 1 is working, the output shafts of the two hydraulic cylinders 216 extend, and the leveling frame 21 flips downward, so that the right side of the leveling frame 21 contacts the ground, driving the loosening rake 23 to contact the ground, so that the loosened soil is fully mixed with the fertilizer under the turning of the loosening rake 23, and the ground is leveled through the right bottom of the leveling frame 21, so that the fertilizer is fully in contact with the soil.
