Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of seedling throwing machine, and particularly relates to a seedling throwing machine for reducing damage of tobacco seedlings. BACKGROUND

[0002] Tobacco is one of the main economic crops in China, and the seedling transplanting method is mainly used. However, the existing seedling throwing machine usually puts the seedlings into the seedling throwing pipe and then falls to throw the seedlings. Since the seedlings carry soil blocks, the falling speed is usually too fast, which causes the seedlings to be easily damaged by vibration when falling to the ground, thereby affecting the survival rate of the seedling transplanting and throwing. SUMMARY

[0003] In view of the defects of the prior art, the present application provides a seedling throwing machine for reducing damage of tobacco seedlings, which has the advantage of reducing damage of seedlings during seedling transplanting and throwing, and solves the problem of the existing seedling throwing machine for reducing damage of tobacco seedlings, i.e., the seedlings are usually damaged by vibration when falling to the ground due to the fast falling speed caused by carrying soil blocks, thereby affecting the survival rate of the seedling transplanting and throwing.

[0004] To achieve the above-mentioned purpose of reducing damage of seedlings during seedling transplanting and throwing, the present application provides the following technical scheme: A seedling throwing machine for reducing damage of tobacco seedlings, comprising: a moving seat, two push rods are fixedly installed on one side of the moving seat, a support frame is arranged on one side of the moving seat, a fixed disc is fixedly installed on one side of the support frame, a rotating disc is rotatably installed on one side of the fixed disc, a plurality of guide pipes are fixedly installed on the surface of the rotating disc, and a seedling throwing mechanism is arranged on one side of the fixed disc, wherein the seedling throwing mechanism comprises a seedling throwing pipe fixedly installed on one side of the fixed disc, a speed reduction assembly is arranged on one side of the seedling throwing pipe, and a soil opening assembly is further arranged on one side of the seedling throwing pipe.

[0005] Based on the above technical features: when in use, the seedlings to be transplanted and thrown are placed in the guide pipes, the seedlings in the guide pipes can be transplanted and thrown through the seedling throwing pipe when the guide pipes coincide with the seedling throwing pipe by rotating the rotating disc, the falling speed of the seedlings can be adjusted by the speed reduction assembly when the seedlings fall, thereby reducing the impact damage of the seedlings when falling to the ground, and the soil opening assembly can open the soil to place the seedlings in the soil, thereby reducing the difficulty of the seedlings entering the soil.

[0006] As a preferred scheme of the seedling throwing machine for reducing damage of tobacco seedlings, the speed reduction assembly comprises two connecting grooves opened on the surface of the seedling throwing pipe, a fixed frame is fixedly installed on one side of each of the two connecting grooves, a plurality of fixed plates are arranged on one side of the fixed frame, a buffer tab is arranged on one side of each of the fixed plates, and the buffer tab on one side penetrates through the connecting groove and extends to the inside of the seedling throwing pipe.

[0007] Based on the above technical features: in use, the plurality of buffer tabs located on one side of the two connecting grooves can contact the soil block of the seedling, thereby adjusting the falling speed of the seedling to reduce the impact force when the seedling contacts the ground.

[0008] As a preferred scheme of the transplanting and seedling throwing machine for reducing tobacco seedling damage: the buffer tab is rotatably connected with the fixed plate, and a torsional spring is fixedly connected between the buffer tab and the fixed plate.

[0009] Based on the above technical features: the torsional spring provides elastic support between the buffer tab and the fixed plate, can absorb part of the falling kinetic energy during contact, and then gradually release the energy, avoiding sudden impact on the seedling. The torsional spring also has an automatic reset function, so that the buffer tab can return to the original position after each contact, ready to contact the next seedling.

[0010] As a preferred scheme of the transplanting and seedling throwing machine for reducing tobacco seedling damage: the surface of the buffer tab is provided in a slope shape, and the plurality of buffer tabs are equidistantly distributed.

[0011] Based on the above technical features: when the seedling soil block contacts the buffer tab, it will contact the slope of the buffer tab, which can disperse the impact force and reduce the direct vertical impact by changing the contact angle. This oblique sliding contact method reduces the pressure on the seedling and reduces the possible damage.

[0012] As a preferred scheme of the transplanting and seedling throwing machine for reducing tobacco seedling damage: a screw rod is rotatably installed on one side of the fixed plate, one side of the fixed plate is slidably connected with a fixed frame, and one end of the screw rod is threadedly connected with the fixed frame.

[0013] Based on the above technical features: in use, the screw rod and the fixed frame can be threadedly moved to adjust the distance of the buffer tab entering the inside of the seedling throwing pipe, thereby adapting to the slow falling of seedling soil blocks of different sizes.

[0015] Based on the above technical features: when opening the soil, the support frame is moved through the electric sliding rail, so that the support frame moves downward, synchronously driving the two soil opening shovels to move downward, and the soil opening shovel synchronously drives the support plate to move downward when moving downward, and when the support plate reaches the other side of the slide, the support plate can be rotated to form an inclined direction and pull up the corresponding soil opening shovel to open, and the two soil opening shovels can be conveniently inserted into the soil to open the soil and put the seedlings into the soil.

[0016] As a preferred scheme of the tobacco seedling transplanting and seeding machine for reducing damage, one side of the soil opening shovel is conical, and the guide pipe is circular truncated cone.

[0017] Based on the above technical features: the two conical soil opening shovels can be more conveniently inserted into the soil to open the soil, and the circular truncated cone guide pipe can better guide the seedlings.

[0018] Compared with the prior art, the tobacco seedling transplanting and seeding machine for reducing damage has the following beneficial effects: In use, the seedlings to be transplanted and seeded can be placed in the guide pipe, and when the guide pipe coincides with the seeding pipe, the seedlings in the guide pipe can be transplanted and seeded through the seeding pipe. When the seedlings fall, the falling speed of the seedlings can be adjusted by the buffer assembly, so as to reduce the impact damage of the seedlings when falling to the ground. The soil opening assembly can also open the soil and put the seedlings into the soil, reducing the difficulty of the seedlings entering the soil. In use, the seedlings to be transplanted and seeded can be placed in the guide pipe, and when the guide pipe coincides with the seeding pipe, the seedlings in the guide pipe can be transplanted and seeded through the seeding pipe. When the seedlings fall, the falling speed of the seedlings can be adjusted by the buffer assembly, so as to reduce the impact damage of the seedlings when falling to the ground. The soil opening assembly can also open the soil and put the seedlings into the soil, reducing the difficulty of the seedlings entering the soil. BRIEF DESCRIPTION OF DRAWINGS
