Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically a high-speed rice transplanter and ditching machine suitable for cold-watered paddy fields. Background Technology
[0002] A rice transplanter is an agricultural machine used to plant rice seedlings in paddy fields. During planting, a mechanical claw first removes several rice seedlings from the seedbed and plants them into the soil of the field. In order to maintain a right angle between the seedbed and the ground, the front end of the mechanical claw must move in an elliptical motion curve. However, existing rice transplanters have limited functions and cannot meet the requirements for qualified rice transplanting in cold-watered fields. After transplanting in cold-watered fields, the seedlings will be affected by the cold water in the field, resulting in low soil and water temperatures. This leads to poor rice growth and even withering and death of the seedlings. Therefore, this utility model proposes a high-speed rice transplanter and ditching machine suitable for cold-watered fields to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a high-speed rice transplanter and ditching machine suitable for cold-watered paddy fields, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-speed rice transplanter and ditching machine suitable for cold-waterlogged fields, comprising...
[0005] The vehicle body has a driver's seat fixedly installed on the top, a fixed frame fixedly connected to the bottom, a movable plate fixedly connected to the side of the fixed frame, a seedling rack movably connected to the top of the movable plate, a seedling planting mechanism fixedly connected to the side of the fixed frame, and a ditching mechanism fixedly connected to the bottom of the fixed frame. Preferably, a rotating axle is movably connected to the bottom of the vehicle body, and a wheel is fixedly connected to the side of the rotating axle.
[0006] The seedling planting mechanism includes a rammed earth platform, a rotating shaft movably mounted on the side of the rammed earth platform, a rotating gear machine movably connected to the side of the rotating shaft, and a mechanical claw movably connected to the side of the rotating gear machine.
[0007] Preferably, the trenching mechanism includes a soil-breaking shovel, a connecting rod fixedly connected to the side of the soil-breaking shovel, a positioning seat fixedly connected to the top of the connecting rod, and a fixed wheel movably connected to the side of the positioning seat.
[0008] Preferably, a drive shaft is movably connected to the side of the ramming machine, and a groove is provided on the top of the ramming platform, with the rotating shaft installed in the groove. Preferably, a first chain is sleeved on the rotating shaft, and the other end of the first chain is sleeved on the drive shaft. A second chain is sleeved on the side of the drive shaft, and the other end of the second chain is sleeved on the wheel axle of the vehicle body.
[0009] Preferably, there are two fixed wheels, which are mounted in a "V" shape on the side of the positioning seat, and the rounded edges of the fixed wheels are serrated.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the wheel drives the rotating shaft to rotate, which in turn drives the second chain to rotate, and the second chain drives the transmission shaft, which in turn drives the first chain mounted on the side to rotate. The rotation of the first chain drives the seedling planting mechanism to start moving, and the mechanical claw on the seedling planting mechanism starts to plant seedlings. The chain is connected to the rotating shaft of the wheel to achieve synchronous rotation, which will prevent the seedlings from being planted at different spacings. The trenching mechanism and the soil tamping platform on the seedling planting mechanism work together to open trenches with a soil-breaking shovel, and then use a fixed wheel "V" shaped mechanism to squeeze the wet soil opened by the soil-breaking shovel to both sides to solidify it. Then, the soil protruding at the top is compacted downward by the soil tamping machine structure, thereby forming a solid trench. Trenching and drainage can lower the water level, improve soil permeability, increase soil nutrients, promote rice growth and development, and increase rice yield. Attached Figure Description

[0017] The vehicle body 1 has a driver's seat 2 fixedly installed on the top of the vehicle body 1, a fixed frame 3 fixedly connected to the bottom of the vehicle body 1, a movable plate 4 fixedly connected to the side of the fixed frame 3, a seedling rack 5 movably connected to the top of the movable plate 4, a seedling insertion mechanism 6 fixedly connected to the side of the fixed frame 3, a trenching mechanism 7 fixedly connected to the bottom of the fixed frame 3, and a rotating axle 8 movably connected to the bottom of the vehicle body 1, with wheels fixedly connected to the side of the rotating axle 8.
[0018] The seedling transplanting mechanism 6 includes a rammed earth platform 9. A rotating shaft 10 is movably installed on the side of the rammed earth platform 9. A rotating gear machine 11 is movably connected to the side of the rotating shaft 10. A mechanical claw 12 is movably connected to the side of the rotating gear machine 11. The rotating gear machine 11 movably connected to the side of the rammed earth platform 9 drives the mechanical claw 12 to rotate, thereby picking up the seedlings from the seedling clamp and then inserting them into the wet soil. Under the squeezing and compacting action of the rammed earth platform 9, the wet soil on the side of the rammed earth platform 9 will accumulate and pile up at the seedling insertion point of the mechanical claw 12. This makes the seedlings planted more firmly, improves the seedling establishment rate and the ability to resist lodging.
[0019] The trenching mechanism 7 includes a soil-breaking shovel 13. A connecting rod is fixedly connected to the side of the soil-breaking shovel 13. A positioning seat 14 is fixedly connected to the top of the connecting rod. Fixed wheels 15 are movably connected to the side of the positioning seat 14. There are two fixed wheels 15. The fixed wheels 15 are installed in a "V" shape on the side of the positioning seat 14. The round edge of the fixed wheel 15 is set as a sawtooth. Through the side gear design of the fixed wheel 15, it will move with the vehicle body 1, come into contact with the wet soil and rotate in coordination. The rotating fixed wheel 15 will drive the wet soil to move to both sides, which facilitates the operation of compacting the wet soil.
[0020] A drive shaft is movably connected to the side of the ramming machine. The top of the ramming platform 9 has a groove, and the rotating shaft 10 is installed in the groove. A first chain 16 is sleeved on the rotating shaft 10, and the other end of the first chain 16 is sleeved on the drive shaft. A second chain 17 is sleeved on the side of the drive shaft, and the other end of the second chain 17 is sleeved on the rotating wheel axle 8 of the vehicle body 1. Under the action of the first chain 16 and the second chain 17, the rotating wheel axle 8 and the rotating shaft 10 rotate synchronously, so that the rice planting spacing is always consistent and will not change with the movement of the vehicle body 1, causing the rice planting spacing to be inconsistent.
[0021] In practical use: First, the operator places the seedlings on the seedling rack 5, then sits in the driver's seat 2 and starts the integrated rice transplanter and ditcher. When starting work on a cold-waterlogged field, the soil-breaking shovel 13 on the ditching mechanism 7 first contacts the wet soil at the bottom of the cold-waterlogged field. Then, driven by the vehicle body 1, the soil-breaking shovel 13 will shovel the wet soil to both sides, forming a preliminary trench. After the soil-breaking shovel 13 completes the first step of trenching, the fixed wheel 15 behind the soil-breaking shovel 13 will start working. Through the side gear design of the fixed wheel 15, it will move with the vehicle body 1, contact the wet soil and rotate in coordination. The rotating fixed wheel 15 will drive the wet soil to both sides, making it easier to compact the wet soil, making the wet soil on the sides of the trench more solid and preventing the wet soil after trenching from filling the trench. After the fixed wheel 15 has completed the compaction of the wet soil on the sides, through the inclined design of the soil-tamping platform 9 at the bottom of the transplanting mechanism 6, after the fixed wheel 15 has compacted the wet soil on the sides of the trench, there will still be some relatively loose wet soil on both sides of the top of the trench. However, after the rammed earth platform 9 structure is used, the soil on both sides of the top of the trench will be tilted by the rammed earth platform 9, turning the lateral force into a vertical downward pressure. The wet soil will be compressed and compacted downward under the force, making the entire trench more solid. Under the action of the first chain 16 and the second chain 17, the rotating wheel shaft 8 and the rotating shaft 10 will rotate synchronously, so that the planting spacing is always consistent and will not change with the movement of the vehicle body 1, causing the planting spacing to be inconsistent. Moreover, after the trench is opened by the rammed earth platform 9, the rotating gear machine 11 connected to the side of the rammed earth platform 9 drives the mechanical claw 12 to rotate, which will pick up the seedlings from the seedling clamp and then insert them into the wet soil. Under the squeezing and compaction action of the rammed earth platform 9, the wet soil on the side of the rammed earth platform 9 will accumulate and pile up at the seedling insertion point of the mechanical claw 12. This makes the seedlings planted more solid, improves the seed setting rate and lodging resistance. After the trench is opened, the water level can be lowered, the soil permeability can be improved, the soil nutrients can be increased, the growth and development of rice can be promoted, and the toxicity of cold waterlogging can be reduced.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
