TECHNICAL FIELD

[0001] The utility model belongs to tobacco planting tool field, concretely relates to a tobacco seedling tray transport harrow. BACKGROUND

[0002] At present, most of the tobacco adopts the way of floating seedling to carry on the seedling, the tobacco seed is sowed into the seedling tray, then the seedling tray with tobacco seed is placed into the seedling pool and placed floatingly, because the area of the seedling pool is larger, it needs to use the practical tool to assist placing, at present, the staff only uses the simple wooden stick to place, but it is easy to cause the seedling tray to swing in the water during the placing process, it is not easy to transport, and the working efficiency is affected; the tobacco needs to be transplanted during the growth process, at present, the staff manually drags the seedling tray out, but it is very inconvenient to take the seedling tray in the middle of the seedling pool, if using the ordinary shovel to hold up, because the bottom surface of the seedling tray is a plane and the bottom area is larger than the area of the shovel, it is easy to tilt when holding up, and there is no suitable tool to assist transportation in the process.

[0003] Therefore, it is urgent to provide a tool which can place and transport the seedling tray. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides a tobacco seedling tray transport harrow, which comprises a harrow blade, one end of the harrow blade is connected with a hooking part for hooking the seedling tray, and a pressing part is arranged at a position close to the hooking part of the harrow blade; the hooking part comprises a rotary lock, the rotary lock is connected with a hooking piece, and the rotary lock can make the hooking piece rotate in a certain direction; the pressing part comprises a fixing piece and a pressing piece, the pressing piece is rotationally connected with the harrow blade, the pressing part is used for pressing the tobacco in the seedling tray to prevent the tobacco from tilting and falling, and the fixing piece is used for fixing the rotating position of the pressing piece.

[0005] When placing the seedling tray into the seedling pool in the early stage, only the hooking part is used without using the pressing part, at this time, the pressing part can be rotated to other directions away from the hooking part for fixation, so as to prevent the pressing part from affecting the normal use of the hooking part, the hooking part is rotated to an angle perpendicular to the harrow blade and is fixed, the staff holds the harrow blade to make the hooking part hook the seedling tray, a relatively firm contact is generated between the hooking part and the seedling tray, and the staff can slowly drag the harrow blade to drag the seedling tray to the corresponding position.

[0006] Preferably, the pressing part is detachably connected with the harrow blade, because the growth cycle of the tobacco is relatively long, the pressing part may exist for a long time without use, when the pressing part is not used, the pressing part is detached to reduce the weight of the transport harrow, and the staff uses it more labor-savingly.

[0007] Preferably, the rotation locking member comprises a gear plate and a resilient sheet, the gear plate is fixed to the hooking member and rotationally connected to the rake blade, the outer surface of the rake blade away from the hooking member is hinged with the resilient sheet, the resilient sheet is connected with the rake blade through a spring, and the non-hinged end of the resilient sheet is clamped with the gear plate.

[0014] Preferably, the pressing piece comprises a first pressing claw and a second pressing claw, the first pressing claw and the second pressing claw are connected with a connecting rod, the connecting rod is rotationally connected with the rake, and the connecting rod is connected with the fixing piece.

[0015] When the tobacco needs to be transplanted, the included angle between the hooking piece and the rake is first rotated to an obtuse angle, the first hooking claw and the second hooking claw are both provided with inclined surfaces, and it is easier to extend into the bottom of the seedling tray relative to a vertical plane, and the obtuse angle between the hooking piece and the rake is more convenient for the staff to exert force, after the first hooking claw and the second hooking claw are inserted into the bottom, the hooking piece is rotated to be perpendicular to the rake, the first pressing claw and the second pressing claw are adjusted to be above the tobacco, and the first pressing claw and the second pressing claw are responsible for providing supporting force for the tobacco, so that the seedling tray is prevented from tilting, and the horizontal plane formed by the first hooking claw and the second hooking claw also provides stable supporting force for the seedling tray, at this time, the staff only need to vertically hold the rake to transport the tobacco to the transplanting site.
