Description

TECHNICAL FIELD

[0001] The utility model belongs to portable agricultural seedling transplanting technical field, especially relates to a portable seedling transplanting device for agricultural planting. BACKGROUND

[0002] In the agricultural planting development process, the crop seedlings of concentrated seedling raising need to be transplanted to the low-density planting ground in the growth process, so that the crop seedlings can obtain more growth space, and the existing seedling transplanting device has the following problems in the using process: 1) the existing transplanting device needs to insert the movable expansion head into the soil to form a hole or a pit, but since the operating personnel use different forces to form a hole or a pit each time, the depth of the soil pit is different, which affects the uniform growth of the crop seedlings; 2) the existing expansion head is mostly connected with a handle through a connecting rod, and then the front end head is expanded by using the two-hand gripping or pulling method, but the work intensity is large, and it is difficult to work continuously for a long time by simply relying on the strength of the two hands; 3) the existing expansion head and the push plate do not have a one-way limiting structure, and the operating personnel need to keep their hands in the handle or pulling position all the time, otherwise the device will be closed automatically due to gravity in the disengaging process, which will damage the seedlings.

[0003] After searching, the prior art CN219981519U discloses a portable seedling transplanting device, which comprises two insertion plates hinged to the bottom of the transplanting device, two connection blocks fixedly arranged on the sides of the two insertion plates away from each other, two pedals fixedly installed on the two sides of the transplanting device, a compression mechanism arranged in the transplanting device, and the compression mechanism comprises a moving block, a compression plate and a sliding groove, the two inner walls of the transplanting device are provided with the sliding grooves, the moving blocks are slidably connected to the inner walls of the two sliding grooves, the compression plates are hinged to the sides of the two moving blocks close to each other, the compression plates are used for compressing the seedlings transplanted in the transplanting device, and the curved rods are fixedly installed on the top of the two compression plates and extend out of the transplanting device; the above technical scheme can move the U-shaped plate downward by extruding the fixed plate downward, drive the moving block to move by the curved rod, and move the compression plate downward, so as to compress the transplanted seedlings; however, the above technical scheme cannot be adjusted up and down when in use, and the opening depth cannot be adjusted according to the needs of the seedlings, so the adaptability is not strong.

[0004] For example, the prior art CN222396149U discloses a portable seedling transplanting device, comprising a measuring assembly arranged on one side of a transplanting device cylinder; a stirring nozzle is rotatably connected to the bottom of the transplanting device cylinder, the stirring nozzle is symmetrically distributed about the bisector of the transplanting device cylinder, a connecting block is fixedly connected to one side of the stirring nozzle, one end of the connecting block is connected with a pulling steel wire rope, limit rods are fixedly connected to the two sides of the transplanting device cylinder, through holes are formed in the limit rods, the pulling steel wire rope is inserted into the through holes, the measuring assembly comprises a box body fixed to one side of the transplanting device cylinder, an opening is formed in one side of the box body, a rotating shaft is rotatably connected to the opening, a clockwork is arranged on the outer wall of the rotating shaft, a measuring tape is wound around the outer wall of the clockwork, one end of the measuring tape is connected with a moving rod, the height of the moving rod is greater than the height of the box body, and the moving rod and the box body are in sliding connection; the above technical scheme can control the distance between two seedlings; however, the operator needs to pull the pull ring and the pulling steel wire rope to open the stirring nozzle during use, which requires a large hand strength of the operator, and the stirring nozzle cannot be limited to the depth of insertion into the soil, so that the depths of the holes are different, the seedling branches and leaves are covered in the deep transplanting holes, and the growth of the crops is affected.
