Description

Technical Field

[0001] The invention relates to the technical field of spreading machines, in particular to a soil conditioner spreading machine. Background Art

[0002] Agricultural planting is one of the important industries. Agricultural planting guarantees our food output. With the development of science and technology, agricultural planting is also moving towards scientific planting. For agricultural planting, soil conditions are extremely important factors for crop growth. Good soil conditions can ensure the good growth of crops. In order to ensure favorable soil conditions, soil conditioners need to be spread before crop planting to improve soil physical properties and promote crop nutrient absorption, thereby improving soil structure, regulating soil pH, increasing soil fertility, reducing soil erosion, and preventing diseases and insect pests. It can be seen that soil conditioners play a vital role in agricultural planting. In the process of spreading soil conditioners, a spreader is needed to spread them.

[0003] In the prior art, the amount of soil conditioner spread by the spreader is generally random during the spreading process, resulting in different amounts of soil conditioner spread in different places during the spreading process. Too much soil conditioner or too much water cannot achieve a good improvement effect. Different soil conditioners have different effective ranges of action, resulting in different spreading intervals. At the same time, after the soil conditioner is spread, in order to make the conditioner penetrate into the soil more quickly, manual watering is required after the spreading is completed, which greatly increases the labor intensity.

[0020] 1. The main shaft is driven to rotate by a servo motor, and the main body is moved by a walking mechanism. During the movement, the main shaft makes the rack reciprocate through the cooperation of the convex block and the first spring, so that the rotating shaft rotates periodically, and the rotating shaft drives the partition plate to rotate. Multiple partition plates form multiple spaces with the same volume. As the partition plates rotate, a certain amount of soil conditioner can be spread in the soil as the main body moves, thereby achieving quantitative spreading and avoiding too much or too little spreading of soil conditioner;

The application spacing can be adjusted according to the effective range of different soil conditioners, so that the spreader can be adapted to the use of different soil conditioners.

[0023] 4. During the rotation process, the convex block can not only drive the rack to reciprocate, but also make the active column reciprocate through the contact plate and the fourth spring, thereby making the driven column reciprocate, and then making the stirring plate reciprocate, constantly stirring the soil conditioner in the hopper, thereby ensuring that it smoothly enters between the two partition plates and fills the space to avoid accumulation;

[0024] 5. During the application of soil conditioner, the watering mechanism is set up to sprinkle water while spreading, avoiding the tedious operation of subsequent manual watering and greatly reducing labor intensity;

[0025] 6. Through the setting of the loosening knife, the soil can be turned over during the main movement, which can ensure that the improver is spread into the soil. Loosening knives are set on both sides, so that the spreader can be used in both directions, which is more convenient to use.

[0026] 7. When the loosening knife on one side is loosening the soil, the loosening knife on the other side is in a raised state. With the setting of the guide plate, the water pumped out by the fourth pipe falls on the guide plate and then flows down along the loosening knife, which can ensure that the pumped water is more evenly sprinkled into the soil, thereby more evenly mixing with the soil conditioner.

[0038] Reference Figure 1-10 A soil conditioner spreader includes a hollow main body 1, in which a spreading mechanism, a walking mechanism and a watering mechanism are arranged. A hopper 18 and a water tank 43 are fixedly connected through the top wall of the main body 1, and the thickness of the bottom wall of the water tank 43 gradually decreases from both ends to the center, so as to facilitate the accumulation of water.

[0039] The spreading mechanism consists of a quantitative component, a regulating component and a stirring component. The quantitative component is used to quantitatively spread the improver, the regulating component is used to regulate the spreading interval, and the stirring component is used to stir the improver. The quantitative component includes a servo motor 2, which is fixedly connected to the inner wall of the main body 1 through a bracket. The output shaft of the servo motor 2 is fixedly connected to the main shaft 3, and the main shaft 3 is penetrated and fixedly connected to the first gear 5;

[0040] The walking mechanism is used for the movement of the main body 1. The walking mechanism includes two wheel axles 6 and an intermediate shaft 36. The wheel axles 6 are rotatably connected to the main body 1 through bearings. One of the wheel axles 6 is fixedly connected with a first electric clutch 7. The intermediate shaft 36 is rotatably connected to the inner wall of the main body 1 through bearings.

[0041] The watering mechanism is used to pump out the water in the water tank 43 to help the improver penetrate into the soil.

[0042] The quantitative assembly also includes a material passing cylinder 16, which is a cylinder body with openings on both the upper and lower sides (such as Figure 3 and Figure 4As shown, the material barrel 16 is fixedly connected to the bottom wall of the main body 1, the hopper 18 is fixedly connected to the material barrel 16, the hopper 18 is connected to the material barrel 16, the material barrel 16 is rotatably connected to the shaft 13 through a bearing, the side wall of the shaft 13 located in the inner section of the material barrel 16 is fixedly connected to a plurality of partition plates 17, and one end of the shaft 13 located outside the material barrel 16 is rotatably connected to the second electric clutch 14 through a bearing, the second electric clutch 14 can be combined with the shaft 13 when the power is on, and disconnected when the power is off. The third gear 15 is rotatably connected to the main body 1 through a one-way bearing, a fixing block 9 is fixedly connected to the inner bottom wall of the main body 1, and a rack 10 is slidably connected to the fixing block 9. The one-way bearing is arranged so that when the rack 10 moves toward the third gear 15, the third gear 15 is driven to rotate, and the third gear 15 does not drive the second electric clutch 14 to rotate. When the rack 10 moves away from the third gear 15, the second electric clutch 14 can be driven to rotate. The side wall of the rack 10 is fixedly connected to a top plate 11, and a space between the top plate 11 and the fixing block 9 is formed. A plurality of first springs 12 are fixedly connected, a protrusion 4 is fixedly connected through the main shaft 3, the rack 10 is meshed with the third gear 15, the ratio of the number of teeth of the third gear 15 to the rack 10 is the number of partition plates 17, and the space is divided by the partition plates 17, and the ratio of the number of teeth of the third gear 15 to the rack 10 ensures that when the rack 10 drives the third gear 15 to rotate, the space between the two partition plates 17 can just coincide with the opening of the barrel 16, and the rotation of the third gear 15 drives the rotating shaft 13 to rotate, so that the partition The plate 17 rotates, so that the soil conditioner between the two partition plates 17 falls through the opening below the barrel 16 for spreading. At the same time, the space between the two partition plates 17 after spreading rotates to coincide with the opening above the barrel 16. At this time, the soil conditioner in the hopper 18 falls into the space and waits to be rotated for spreading. Since the volume of the space between the two partition plates 17 is a fixed value, the amount of soil conditioner spread each time the partition plate 17 rotates is also a fixed value, thereby avoiding excessive or insufficient spreading that affects the improvement effect.

[0043] The control assembly includes a hollow oil tank 19, and a hole (such as Figure 6As shown), the oil tank 19 is connected to the outside to ensure that the hydraulic oil can flow into the inside. The oil tank 19 is fixedly connected to the inner bottom wall of the main body 1. The upper surface of the oil tank 19 is fixedly connected with a fixed sleeve 20 and a vertical cylinder 21. The fixed sleeve 20 is sealed and slidably connected with a piston 22. The rack 10 is fixedly connected to the side wall of the piston 22. The fixed sleeve 20 and the oil tank 19 are jointly penetrated and fixedly connected with a first pipe 23. The vertical cylinder 21 and the fixed sleeve 20 are jointly penetrated and fixedly connected with a second pipe 24. The vertical cylinder 21 and the oil tank 19 are jointly penetrated and fixedly connected with a third pipe 25. The vertical cylinder 21 is sealed and slidably connected with a trigger plug 26. A second spring 27 is fixedly connected between the trigger plug 26 and the inner bottom wall of the vertical cylinder 21. The inner side wall of the vertical cylinder 21 is fixedly connected with a support plate 28. The support plate 28 penetrates and slides through the support plate 28. A lifting column 29 is connected, and a delay switch 30 is fixedly connected to the lower surface of the lifting column 29. After the delay switch 30 is pressed, the circuit can be energized for a certain period of time and then automatically powered off. This is a prior art and will not be described in detail here. A screw 32 is rotatably connected to the top wall of the main body 1 through a bearing. A section of the screw 32 located inside the main body 1 is provided with a thread and is threadedly connected to the lifting column 29. One end of the screw 32 located outside the main body 1 is fixedly connected to a rotating wheel 33. The cross-section of the lifting column 29 is rectangular, so as to prevent it from rotating with the screw 32. A first solenoid valve 31 is provided in the third tube 25. The first solenoid valve 31 is a normally closed solenoid valve. When powered on, the first solenoid valve 31, the first electric clutch 7, the second electric clutch 14, and the delay switch 33 are in contact with each other. 0 is electrically connected through a wire. After the delay switch 30 is pressed, the first solenoid valve 31, the first electric clutch 7, and the second electric clutch 14 are energized for a certain period of time, and then the power is cut off. The energization time is the time for the servo motor 2 to rotate 90°, that is, the time for the protrusion 4 to rotate from the horizontal state to the vertical state. The oil tank 19 is filled with hydraulic oil. The main shaft 3 drives the protrusion 4 to rotate. The rotation of the protrusion 4 cooperates with the first spring 12, so that the top plate 11 drives the rack 10 to reciprocate. During the reciprocating motion of the rack 10, the third gear 15 is driven to rotate. When the rack 10 moves away from the third gear 15, the third gear 15 drives the second electric clutch 14 to rotate. At this time, the second electric clutch 14 is disconnected from the rotating shaft 13. At this time, the rotating shaft 13 does not rotate. At the same time During the reciprocating motion of the rack 10, the piston 22 is driven to reciprocate. When the piston 22 moves toward the third gear 15, the hydraulic oil in the oil tank 19 is sucked into the fixed sleeve 20 through the first pipe 23. When the piston 22 moves away from the third gear 15, the sucked hydraulic oil is pumped into the vertical cylinder 21 through the second pipe 24, so that the trigger plug 26 rises. As the main body 1 continues to move forward, the height of the trigger plug 26 continues to rise until the piston 22 pumps the hydraulic oil into the vertical cylinder 21, so that the trigger plug 26 triggers the delay switch 30 to spread the soil conditioner. By adjusting the position of the delay switch 30, the spreading interval can be adjusted, so that the spreader can be suitable for spreading soil conditioners with different ranges of action, and has a wider range of applicability.

[0044] The stirring assembly includes a fifth tube 50, which is fixedly connected to the hopper 18 through the fifth tube 50, and the two ends of the fifth tube 50 are respectively sealed and slidably connected with an active column 51 and a driven column 54, and the space between the active column 51 and the driven column 54 is filled with hydraulic oil. The end of the active column 51 located outside the fifth tube 50 is fixedly connected with a contact plate 52, and the contact plate 52 is an arc plate (such as Figure 4 As shown), it can ensure that the protrusion 4 can better resist it when it rotates, so as to avoid it hindering the rotation of the protrusion 4. A plurality of fourth springs 53 are fixedly connected between the contact plate 52 and the hopper 18. A plurality of side rods 55 are fixedly connected to the side wall of a section outside the fifth tube 50 of the driven column 54. The side rods 55 are jointly fixedly connected with a stirring plate 56. During the rotation of the protrusion 4, it will continue to resist the contact plate 52. Through the cooperation with the fourth spring 53, the active column 51 reciprocates, and the active column 51 drives the driven column 54 to reciprocate through the hydraulic oil. The driven column 54 drives the stirring plate 56 to reciprocate up and down through the side rods 55, and continuously stirs the soil conditioner in the hopper 18, so that it flows into the space between the two partition plates 17 and fills the space to avoid accumulation.

[0045] The walking mechanism also includes a second gear 8, which is fixedly connected to the first electric clutch 7. The first electric clutch 7 can be disconnected from the axle 6 when energized, and engaged with the axle 6 when powered off. The two axles 6 are both fixedly connected with a first pulley 35, and the intermediate shaft 36 is fixedly connected with a second pulley 37. The first pulley 35 and the second pulley 37 are jointly tensioned with a synchronous belt 38, and both ends of the two axles 6 are fixedly connected with walking wheels 34.

[0046] The watering mechanism includes a water cylinder 44 with a concave cross section, the water cylinder 44 is fixedly connected to the bottom wall of the water tank 43, and a pump plug 47 is slidably connected to the bottom wall of the water cylinder 44. Fig. 9 As shown, a sealing rubber ring is arranged between it and the inner wall of the water cylinder 44, a third spring 48 is fixedly connected between the water pump plug 47 and the lower surface of the water cylinder 44, a cam 49 is fixedly connected through the intermediate shaft 36, and two fourth tubes 45 are fixedly connected through the water cylinder 44 and the main body 1, and a second electromagnetic valve 46 is arranged in the fourth tube 45. The second electromagnetic valve 46 is electrically connected to the servo motor 2 through a wire. The circuit connection relationship between the second electromagnetic valve 46 and the servo motor 2 is as shown in FIG. Fig.10As shown, the second solenoid valve 46 is connected in series with a diode and then connected in series with the servo motor 2. The servo motor 2 is a DC servo motor. When the current direction changes, its direction of rotation also changes accordingly. The second solenoid valve 46 is a normally closed solenoid valve, which can be opened by powering on. The moving direction of the main body 1 can be controlled by controlling the power-on direction of the servo motor 2. The positive and negative directions of the current also change the opening and closing states of the two second solenoid valves 46, so that the second solenoid valve 46 away from the forward direction is in an open state, thereby ensuring that no matter what the forward direction is, the soil conditioner is applied before watering. During the movement of the main body 1, the second pulley 37 passes through the intermediate shaft 36 The cam 49 is driven to rotate. The cam 49 is opposed to the water pump plug 47 to drive the water pump plug 47 to move upward. Since there is a certain amount of water in the water tank 43, it has a certain gravity, and the resistance to pumping water into the fourth pipe 45 is relatively small. The water pump plug 47 moves upward to pump water into the fourth pipe 45, and is discharged through the fourth pipe 45, falls on the guide plate 42, flows down along the guide plate 42, and falls evenly into the soil after spreading through the loosening knife 41 on the other side of the forward direction, so that the soil conditioner penetrates into the soil with the water flow. After spreading the soil conditioner, water is automatically sprinkled to avoid subsequent manual sprinkling, greatly reducing labor intensity and improving the degree of automation.

[0047] Two side blocks 39 are fixedly connected to the two opposite side walls of the main body 1, and a rod 40 is rotatably connected between the two corresponding side blocks 39 through a bearing. A plurality of loosening knives 41 are fixedly connected through the rod 40. When the main body 1 moves in one direction, the loosening knives 41 in the forward direction will collide with the main body 1, and the soil will be broken by the loosening knives 41 to ensure that the soil conditioner is spread in the soil, while the loosening knives 41 on the other side will rotate and lift up. By arranging the loosening knives 41 on both sides of the main body 1, the main body 1 can be used when moving in two directions.

[0048] One-way valves are provided in both the first tube 23 and the second tube 24 . The one-way valve in the first tube 23 only allows hydraulic oil to enter the fixed sleeve 20 from the oil tank 19 , and the one-way valve in the second tube 24 only allows hydraulic oil to enter the vertical cylinder 21 from the fixed sleeve 20 .

[0049] A one-way valve is provided in the fourth tube 45, and the one-way valve in the fourth tube 45 only allows water to enter the fourth tube 45 from the water cylinder 44. The side walls of the loosening knife 41 located on the same side are fixedly connected with a guide plate 42, and the thickness of the guide plate 42 gradually decreases from top to bottom, so that water falling thereon can fall along its surface.

[0050] The side wall of the running wheel 34 is provided with a plurality of plate-like protrusions, and the arrangement of the plate-like protrusions increases the gripping force of the running wheel 34, thereby ensuring that the running wheel 34 stably drives the main body 1 forward and avoids slipping.

[0051] In the present invention, firstly, the wheel 33 is rotated according to the required spreading spacing, and the wheel 33 drives the screw 32 to rotate. The rotation of the screw 32 causes the lifting column 29 to rise or fall through the threaded connection, thereby adjusting the position of the delay switch 30, and then the water tank 43 is filled with water, and the soil conditioner is filled into the hopper 18. After the adjustment is completed, the servo motor 2 is supplied with electricity in the required direction according to the required direction of travel.

[0052] After the servo motor 2 is energized, it drives the main shaft 3 to rotate, and the rotation of the main shaft 3 drives the first gear 5 to rotate, and the first gear 5 drives the second gear 8 to rotate, and the second gear 8 drives the wheel shaft 6 to rotate through the first electric clutch 7, and then through the transmission of the first pulley 35, the second pulley 37 and the synchronous belt 38, the two wheel shafts 6 rotate synchronously, so that the walking wheel 34 rotates, driving the main body 1 forward, and when the main body 1 moves forward, the soil is broken by the loosening knife 41 in the forward direction.

[0053] During the forward movement of the main body 1, the main shaft 3 drives the protrusion 4 to rotate, and the rotation of the protrusion 4 cooperates with the first spring 12, so that the top plate 11 drives the rack 10 to reciprocate. During the reciprocating movement of the rack 10, the third gear 15 is driven to rotate. When the rack 10 moves away from the third gear 15, the third gear 15 drives the second electric clutch 14 to rotate. At this time, the second electric clutch 14 and the rotating shaft 13 are in a disconnected state. At this time, the rotating shaft 13 does not rotate. At the same time, during the reciprocating movement of the rack 10, the piston 22 is driven to reciprocate. When the piston 22 moves toward the third gear 15, the hydraulic oil in the oil tank 19 is sucked into the fixed sleeve 20 through the first pipe 23. When the piston 22 moves away from the third gear 15, the sucked hydraulic oil will be pumped into the vertical cylinder 21 through the second pipe 24, so that the trigger plug 26 rises.

[0054] As the main body 1 continues to move forward, the height of the trigger plug 26 continues to rise until the piston 22 pumps the hydraulic oil into the vertical cylinder 21, so that the trigger plug 26 triggers the delay switch 30. At this time, the first electric clutch 7 is energized, and the first electric clutch 7 is disconnected from the wheel shaft 6. At this time, the wheel shaft 6 stops rotating, and the main body 1 no longer moves forward. The second electric clutch 14 is energized, and the second electric clutch 14 is combined with the rotating shaft 13. When the rack 10 moves away from the third gear 15, the third gear 15 rotates to drive the rotating shaft 13 to rotate, so that The partition plate 17 is rotated so that the soil conditioner between the two partition plates 17 falls through the opening below the barrel 16 for spreading. At the same time, the space between the two partition plates 17 after spreading rotates to coincide with the opening above the barrel 16. At this time, the soil conditioner in the hopper 18 falls into the space and waits to be rotated for spreading. During this process, the first solenoid valve 31 is in an energized open state, so that the hydraulic oil in the vertical cylinder 21 flows back into the oil tank 19 through the third pipe 25, thereby resetting the trigger plug 26.

[0055] After the spreading is completed, the first electric clutch 7, the second electric clutch 14 and the first electromagnetic valve 31 are de-energized, and the first electric clutch 7 is engaged with the axle 6 again, and the axle 6 continues to rotate, so that the main body 1 moves forward until it moves to the next spreading position, and the spreading is performed according to the above steps.

[0056] During the rotation of the protrusion 4, it will continue to abut against the contact plate 52, and through cooperation with the fourth spring 53, the active column 51 will reciprocate, and the active column 51 will drive the driven column 54 to reciprocate through the hydraulic oil, and the driven column 54 will drive the stirring plate 56 to reciprocate up and down through the side rod 55, constantly stirring the soil conditioner in the hopper 18, so that it flows into the space between the two partition plates 17 and fills the space to avoid accumulation.

[0057] During the movement of the main body 1, the second pulley 37 drives the cam 49 to rotate through the intermediate shaft 36. The cam 49 drives the water pump plug 47 to move upward by counteracting the water pump plug 47. Since there is a certain amount of water in the water tank 43, it has a certain gravity, and the resistance to pumping water into the fourth pipe 45 is relatively small. The upward movement of the water pump plug 47 will pump water into the fourth pipe 45, and discharge it through the fourth pipe 45, fall on the guide plate 42, flow down along the guide plate 42, and evenly fall into the soil after spreading through the loosening knife 41 on the other side of the forward direction, so that the soil conditioner penetrates into the soil with the water flow.
