Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to a rice slow-release fertilizer application machine and method. Background Technology

[0002] Slow-release fertilizer is a type of fertilizer that is processed to dissolve and release slowly after application. It is commonly used as a base fertilizer in crop cultivation. When applying slow-release fertilizer, a relatively deep application depth is usually chosen, typically the middle to lower depth of the crop root system. This ensures that the fertilizer is released slowly over a long period of time to promote absorption throughout the crop's entire growth cycle. For slow-release fertilizer application in paddy fields, it needs to be combined with soil tillage to ensure that the fertilizer is applied into the deeper soil layers while keeping the soil surface loose for subsequent rice growth. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a rice slow-release fertilizer application machine and method. This machine and method utilize a rod-shaped tillage and fertilization structure and a swing-type drive structure to apply slow-release fertilizer during the tillage process. By combining tillage and fertilization, the slow-release fertilizer is applied to the appropriate depth of the soil, thus ensuring its proper release.

[0017] The drive motor is fixedly mounted on the frame, and the output shaft of the drive motor is connected to one end of the crankshaft via a shaft drive.

[0018] The support shaft consists of two shafts, each of which is configured to engage with two sets of guide sleeves.

[0019] Preferably, the support mechanism comprises:

[0020] An oil seal sleeve is fixedly mounted on a support shaft, and a guide sleeve is movably inserted inside the oil seal sleeve.

[0021] An adjustment assembly is mounted on a frame, and a support shaft is mounted on the adjustment assembly.

[0022] A mudguard assembly is mounted on a support shaft and is configured to cooperate with a guide sleeve.

[0023] Preferably, the adjustment component comprises:

[0025] Mounting base, two mounting bases are set together and respectively set in the guide grooves on the front and rear sides, and the front and rear ends of the support shaft are respectively screwed onto the mounting bases on the front and rear sides by bearings;

[0026] A connecting frame is provided between guide grooves on the front and rear sides, and mounting seats on both the front and rear sides are fixedly mounted on the connecting frame.

[0027] The hydraulic rod is screwed onto the frame via a rotating shaft, and the output shaft of the hydraulic rod is screwed onto a connecting frame.

[0028] Preferably, the mud-blocking assembly comprises:

[0029] A fixing cover is fitted and fixedly installed on the outer side wall of the oil seal sleeve, and the fixing cover is also installed on the guide sleeve;

[0030] The mounting shell is fastened to the side of the fixing cover and covers the guide sleeve.

[0031] Preferably, a connecting rod is fixedly provided on the mounting shell, a transmission rod is fixedly provided at the upper end of the connecting rod, and the movable end of the transmission rod is inserted into the upper port of the guide sleeve. A piston is fixedly provided on the movable end of the transmission rod and is movably provided in the guide sleeve. A cover is sleeved on the upper port of the guide sleeve, and the transmission rod movably passes through the cover. A one-way valve is fixedly provided on both the cover and the piston.

[0032] The working principle of this invention is as follows: When using this device, the frame is installed and fixed on an agricultural vehicle, so that the agricultural vehicle drives the device to move and work, realizing the tilling of the land and the application of slow-release fertilizer; the fertilizer is placed in the hopper, and then fed into the feed pipe through the feed pipe and into the guide sleeve, so that the fertilizer falls from the lower end of the guide sleeve to complete the fertilization; the connecting frame is pushed downward by the hydraulic rod, so that the connecting frame pushes the mounting seat to slide to the lower end of the guide groove, that is, the mounting seat drives the adjustment of the support shaft, and then the support shaft drives the oil seal. The movement of the guide sleeve, driven by the oil seal sleeve, allows it to be placed vertically. A drive motor rotates the crankshaft, which in turn causes the connecting plate to move in a circular motion. This, in turn, moves the upper part of the guide sleeve, which is supported and guided by the oil seal sleeve and a support shaft. The upper part of the guide sleeve, driven by the crankshaft, moves in a circular motion, causing the lower part of the guide sleeve to move in a circular motion, while the guide sleeve slides within the oil seal sleeve. The circular motion of the soil-turning shovel then performs the digging and turning of the soil. This, combined with the fertilizer falling from the guide sleeve, achieves soil tillage and fertilization. When the crankshaft pushes the guide sleeve downwards, the guide sleeve pushes the tilling shovel downwards to scoop soil. At the same time, the guide sleeve moves the feed pipe below the piston, and the fertilizer in the feed pipe falls into the guide sleeve. When the crankshaft drives the guide sleeve upwards, the piston moves to the lower end of the guide sleeve, thus pushing the fertilizer out of the lower end of the guide sleeve. Furthermore, through the cooperation of a one-way valve, the air in the cavity between the piston and the cap inside the guide sleeve is controlled. Fertilizer enters from one side of the cap and exits from the other side of the piston. This ensures that the piston continuously pushes air towards the lower port of the guide sleeve as it reciprocates within the guide sleeve, thus forcing the fertilizer out of the guide sleeve through the lower port. When the equipment is not in operation and is in stepping mode, the connecting frame is lifted upward by the hydraulic rod. This causes the connecting frame to slide the mounting seat to the upper end of the guide groove. In other words, the mounting seat drives the support shaft to move upward, which in turn lifts the oil seal sleeve and the guide sleeve, allowing the guide sleeve to be laid flat. This lifts the soil-turning shovel on the guide sleeve off the ground.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. This device is equipped with a guide sleeve that is guided and supported by a mud-blocking assembly and an oil seal sleeve. A crankshaft drives the upper end of the guide sleeve to move, thereby installing a soil-turning shovel at the lower end of the guide sleeve. A feed pipe and a guide pipe are also provided to connect the hopper to the guide sleeve, thereby realizing tillage and fertilization through the guide sleeve.

[0035] 2. This device has a movable mounting base set by a guide groove and the movement of the mounting base is driven by a hydraulic rod. The support shaft is set on the mounting base, and then the oil seal sleeve is fixed on the support shaft, thereby supporting the guide sleeve. By adjusting the position of the support shaft, the guide sleeve can be placed vertically for tilling and fertilization, or the guide sleeve can be placed flat for the movement and relocation of the device.

[0053] Feed pipe 3-3 is inserted and fixed on the side plate of guide sleeve 3-1, and the feed pipe 3-3 is positioned above the connecting plate 3-2;

[0057] Crankshaft 4-1, wherein the crankshaft 4-1 is spun onto the frame 1 via bearings, and the connecting plates 3-2 on the two sets of guide sleeves 3-1 are respectively spun onto the eccentric shafts on both sides of the crankshaft 4-1 via bearings;

[0058] The drive motor 4-2 is fixedly mounted on the frame 1, and the output shaft of the drive motor 4-2 is connected to one end of the crankshaft 4-1 via shaft drive.

[0062] When the crankshaft 4-1 drives the guide sleeve 3-1 to move, the guide sleeve 3-1 slides inside the oil seal sleeve 5-1, thereby adding heat-conducting lubricating oil into the oil seal sleeve 5-1 to lubricate and cool the sliding guide sleeve 3-1.

[0063] Adjustment component 6 is mounted on frame 1, and support shaft 4-3 is mounted on adjustment component 6;

[0072] Mounting shell 7-2 is fastened to the side of fixing cover 7-1 and covers guide sleeve 3-1;

[0073] The fixed cover 7-1 and the mounting shell 7-2 form a sleeve structure that fits over the oil seal sleeve 5-1. This structure blocks the dirt adhering to the outer wall of the guide sleeve 3-1 when the guide sleeve 3-1 reciprocates, preventing the guide sleeve 3-1 from carrying dirt into the oil seal sleeve 5-1 and damaging its normal operation. The guide sleeve 3-1 slides within the mud-blocking assembly 7 during its travel through the oil seal sleeve 5-1.

[0076] Piston 10 is disposed inside guide sleeve 3-1 and fixedly disposed on transmission rod 9. The upper surface of piston 10 is always set higher than the port of feed pipe 3-3.

[0077] The cover 11 is threadedly fitted onto the upper port of the guide sleeve 3-1, and the transmission rod 9 is movably inserted through the cover 11.

[0078] One-way valves are fixedly installed on both the cover 11 and the piston 10.

[0079] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0080] When using this device, the frame 1 is mounted and fixed on an agricultural vehicle, which then drives the device to move and operate, achieving tillage of the land and application of slow-release fertilizer. Fertilizer is placed in the hopper 2, and then fed through the guide pipe 3-4 into the feed pipe 3-3, and from there into the guide sleeve 3-1. The fertilizer then falls from the lower end of the guide sleeve 3-1, completing the fertilization process. The hydraulic rod 6-4 pushes the connecting frame 6-3 downwards, causing the connecting frame 6-3 to push the mounting base 6-2 to slide to the lower end of the guide groove 6-1. This, in turn, causes the mounting base 6-2 to adjust the position of the support shaft 4-3, which in turn moves the oil seal sleeve 5-1, thus achieving the effect of the oil seal sleeve 5-1 driving the guide... The guide sleeve 3-1 is placed vertically. The drive motor 4-2 rotates the crankshaft 4-1, which in turn drives the connecting plate 3-2 in a circular motion. This causes the upper end of the guide sleeve 3-1 to move via the connecting plate 3-2. The guide sleeve 3-1 is supported and guided by the oil seal sleeve 5-1 and the support shaft 4-3. The upper end of the guide sleeve 3-1 moves in a circular motion via the crankshaft 4-1, which in turn causes the lower end of the guide sleeve 3-1 to move in a circular motion, while the guide sleeve 3-1 slides within the oil seal sleeve 5-1. The soil-turning shovel 3-5 then moves in a circular motion to shovel and turn the soil, thus cooperating with the guide sleeve. Fertilizer falling from 3-1 tills and fertilizes the soil. When crankshaft 4-1 pushes guide sleeve 3-1 downward, guide sleeve 3-1 pushes soil-tilling shovel 3-5 downward to shovel soil. At the same time, guide sleeve 3-1 moves feed pipe 3-3 below piston 10, and fertilizer in feed pipe 3-3 falls into guide sleeve 3-1. When crankshaft 4-1 moves guide sleeve 3-1 upward, piston 10 moves to the lower port of guide sleeve 3-1, pushing fertilizer out of guide sleeve 3-1. Through the cooperation of a one-way valve, air in the cavity between piston 10 and cover 11 within guide sleeve 3-1 is released from cover 1. When the material enters from one side of the guide sleeve 3-1 and exits from the other side of the piston 10, the piston 10 continuously pushes air towards the lower port of the guide sleeve 3-1 as it reciprocates within the guide sleeve 3-1, thus forcing the fertilizer inside the guide sleeve 3-1 out through the lower port of the guide sleeve 3-1. When the equipment is not working and is in a stepping state, the connecting frame 6-3 is lifted upward by the hydraulic rod 6-4, thereby causing the connecting frame to drive the mounting seat 6-2 to slide to the upper end of the guide groove 6-1. That is, the mounting seat 6-2 drives the support shaft 4-3 to move upward, thereby causing the support shaft 4-3 to lift the oil seal sleeve 5-1 and the guide sleeve 3-1, thus flattening the guide sleeve 3-1 and causing the soil-turning shovel 3-5 on the guide sleeve 3-1 to lift off the ground.

[0081] The technical advantages achieved by adopting the above technical solution are as follows:

[0082] 1. This device is equipped with a guide sleeve 3-1 that is guided and supported by a mud-blocking assembly 7 and an oil seal sleeve 5-1. A crankshaft 4-1 is set to drive the upper end of the guide sleeve 3-1 to move, so that a soil-turning shovel 3-5 is installed at the lower end of the guide sleeve 3-1. A feed pipe 3-3 and a guide pipe 3-4 are also provided to connect the hopper 2 to the guide sleeve 3-1, so as to realize tillage and fertilization through the guide sleeve 3-1.

[0083] 2. This device has a movable mounting base 6-2 set in the guide groove 6-1 and is driven to move by the hydraulic rod 6-4. The support shaft 4-3 is set on the mounting base 6-2, and then the oil seal sleeve 5-1 is fixed on the support shaft 4-3, thereby supporting the guide sleeve 3-1. By adjusting the position of the support shaft 4-3, the guide sleeve 3-1 can be placed upright for tilling and fertilization of the device, or the guide sleeve 3-1 can be placed flat for the movement and relocation of the device.

[0084] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.

The support shaft (4-3) drives the oil seal sleeve (5-1) to move, thereby enabling the guide sleeve (3-1) to be placed vertically via the oil seal sleeve (5-1). The drive motor (4-2) drives the crankshaft (4-1) to rotate, and the crankshaft (4-1) drives the connecting plate (3-2) to make a circular motion. This enables the upper end of the guide sleeve (3-1) to move via the connecting plate (3-2). The oil seal sleeve (5-1) supports and guides the guide sleeve (3-1), and the support shaft (4-3) supports the oil seal sleeve (5-1). Thus, the support shaft (4-3) provides fulcrum support for the guide sleeve (3-1). The upper end of the guide sleeve (3-1) is connected to the crankshaft (4-1). The guide sleeve (3-1) moves in a circular motion, causing the lower end of the guide sleeve (3-1) to drive the soil turning shovel (3-5) to move in a circular motion. The guide sleeve (3-1) slides within the oil seal sleeve (5-1), and the soil turning shovel (3-5) moves in a circular motion to shovel and turn the soil. This, combined with the fertilizer falling from the guide sleeve (3-1), achieves soil tillage and fertilization. When the crankshaft (4-1) pushes the guide sleeve (3-1) downwards, the guide sleeve (3-1) pushes the soil turning shovel (3-5) downwards to shovel the soil. At this time, the guide sleeve (3-1) drives the feed pipe (3-3) to move below the piston (10), and the fertilizer in the feed pipe (3-3) falls into the guide sleeve (3-1). When the crankshaft (4-1) drives... When the guide sleeve (3-1) moves upward, the piston (10) moves towards the lower port of the guide sleeve (3-1). The piston (10) pushes the fertilizer in the guide sleeve (3-1) out of the lower port of the guide sleeve (3-1). With the cooperation of the one-way valve, the air in the inner cavity between the piston (10) and the cap (11) in the guide sleeve (3-1) enters from the side of the cap (11) and is discharged from the side of the piston (10). Thus, when the piston (10) reciprocates in the guide sleeve (3-1), it always pushes air towards the lower port of the guide sleeve (3-1), thereby pushing the fertilizer in the guide sleeve (3-1) out of the lower port of the guide sleeve (3-1) through the air.When the equipment is not in operation and is in stepping mode, the connecting frame (6-3) is lifted upward by the hydraulic rod (6-4). This causes the connecting frame (6-3) to slide the mounting base (6-2) to the upper end of the guide groove (6-1). The mounting base (6-2) then moves the support shaft (4-3) upward, which in turn lifts the oil seal sleeve (5-1) and the guide sleeve (3-1), flattening the guide sleeve (3-1) and allowing the soil-turning shovel (3-5) on the guide sleeve (3-1) to lift off the ground.
