[0027] like Figure 1-4As shown, a tobacco seedling transplanter with fixed spacing and no nesting required provided in an embodiment of the present application is now described. The tobacco seedling transplanter with fixed spacing and no nesting required comprises: a bottom frame 1, a vertical pole 2, a pull rod 3, a movable sleeve group, a tension spring 5 and a conical mouth 6. Among them, the bottom frame 1 is a metal ring frame, and its diameter can be placed in tobacco seedlings with soil matrix; the vertical pole 2 is a metal tube, preferably a stainless steel hollow tube, so as to reduce the weight; two vertical poles 2 are symmetrically arranged and welded to the bottom frame 1. One end of the vertical pole 2 is fixed to the bottom frame 1, and the other end is provided with a grip 7, which is the hand-held part of the staff to facilitate holding the tobacco seedling transplanter for work. A fixed rod 8 is provided in the middle of the two vertical poles 2, and the fixed rod 8 is a solid steel bar welded to the two vertical poles 2. The movable sleeve group includes two movable sleeves 4 and a connecting rod 41 connecting the two movable sleeves 4, and the connecting rod 41 is a solid steel bar. In this embodiment, two groups of movable sleeves 4 are provided, and the movable sleeves 4 are slidably sleeved on the vertical pole 2, and the movable sleeves 4 are fixedly connected to the pull rod 3 by welding a short steel bar.

[0028] Among them, one end of the tension spring 5 is hung on the connecting rod 41 of the movable sleeve group below, and the other end is hung on the fixed rod 8. The connecting rod 41 of the movable sleeve group above is set close to the grip rod 7, and the distance between the two is 6-8cm, preferably 7cm, so that when the staff holds the grip rod 7, their fingers can hold the connecting rod 41.

[0029] In this embodiment, the conical mouth 6 has a cavity that can accommodate tobacco seedlings with soil matrix. The conical mouth 6 is symmetrically divided into two arc-shaped fan blades, the two arc-shaped fan blades are hinged on the bottom frame 1, and the two arc-shaped fan blades can be opened. The tip of the conical mouth 6 is set downward, and the outer side surfaces of the two arc-shaped fan blades are respectively connected to one end of the corresponding pull rod 3. When planting, the tobacco seedlings can be placed inside the conical mouth 6 first, and the conical mouth 6 is inserted into the soil. Then the staff holds the grip 7 and pulls the connecting rod 41 upward with fingers, the tension spring 5 is extended, and the connecting rod 41 moves upward to drive the movable sleeve 4 to move upward. The movable sleeve 4 drives the pull rod 3 to move upward through the short steel bar, thereby pulling the two arc-shaped fan blades to open, and the staff then lifts up the entire tobacco seedling transplanter to plant the tobacco seedlings inside the conical mouth 6 in the soil.

[0030] In this embodiment, a telescopic plant spacing ruler 9 is provided on the bottom frame 1, so that the planting spacing can be positioned to meet different plant spacing requirements and different tobacco seedling planting requirements. Specifically, the telescopic plant spacing ruler 9 includes: an L-shaped ruler 91 and a long ruler 92, wherein the vertical bar of the L-shaped ruler 91 is welded and fixed on the bottom frame 1, and the long ruler 92 is slidably arranged on the horizontal bar of the L-shaped ruler 91. The bottom surface of the long ruler 92 is provided with a groove and a sliding assembly with the horizontal bar, and the long ruler 92 and the horizontal bar are provided with a scale. Specifically, a waist-shaped long groove is provided on the horizontal bar, and a through hole is provided on the long ruler 92. A screw with a nut is provided through the through hole and the waist-shaped long groove; the screw passes through the waist-shaped long groove and the through hole and then a nut is screwed. The position of the long ruler 92 can be fixed by tightening the nut. When the length needs to be adjusted, the nut can be loosened. Preferably, the nut is a butterfly nut, which is convenient for twisting. The nut is located on the upper surface of the long ruler 92, which is convenient for operating the nut.

[0031] In this embodiment, a first soft cover is provided on the connecting rod 41 of the movable sleeve group close to the grip rod 7; a second soft cover is provided on the grip rod 7; the first soft cover and the second soft cover are both silicone covers or rubber covers, so as to improve the comfort of the staff in holding and pulling the connecting rod 41.

[0032] In this embodiment, the arc-shaped fan piece is a steel plate, preferably a stainless steel plate, and a perforated iron sheet 10 is welded on the outer side of the arc-shaped fan piece. The pull rod 3 is a steel wire, and one end of the steel wire is arranged in a hook shape and fixed on the perforated iron sheet 10. After being hooked, it can be bent and wound to ensure firm fixation. The diameter of the steel wire is 4-8mm; under the premise of ensuring structural strength, the diameter of the steel wire is preferably 4mm.

[0033] In this embodiment, two vertical pieces 11 are symmetrically welded on the bottom frame 1, and the connecting line of the two vertical pieces 11 and the connecting line of the two vertical poles 2 are cross-shaped; the vertical piece 11 is rotatably installed with two arc-shaped fan pieces through a pin shaft, and the two arc-shaped fan pieces can be pulled to rotate and open through the two vertical poles.

[0034] In this embodiment, the movable sleeve 4 is a ball sleeve. The use of the ball sleeve can reduce the friction of the movable sleeve 4 sliding on the vertical rod 2, saving effort. The ball sleeve can adopt an outer sleeve and an inner sleeve structure, and a plurality of steel balls are arranged on the peripheral wall of the inner sleeve. Alternatively, the inner wall of the ball sleeve is provided with two, three, four or six equal-length grooves, and a plurality of steel balls are placed in each long groove, and the surface of the steel balls is slightly protruding from the inner wall surface. Covers with holes are provided at both ends of the ball sleeve, and the covers are installed by threaded connection, which is convenient for installing the steel balls.

[0035] The tobacco seedling transplanter can directly transplant tobacco seedlings after ridge formation without digging ponds in advance, which reduces an agronomic link and effectively reduces labor costs. At the same time, there is no need to bend down during the entire transplanting process, which effectively alleviates the labor intensity of transplanters. It has a simple structure, strong practicality, and is easy to carry, making it suitable for promotion and use in mountain tobacco areas.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
