Description

Technical Field

[0001] The utility model relates to the technical field of transplanting machines, in particular to a small transplanting machine for flue-cured tobacco planting. Background Art

[0002] Flue-cured tobacco, also known as flue-cured type tobacco, is one of the most widely planted and consumed tobacco types globally, especially playing an important role in the tobacco industries in regions such as the Americas, China, and Europe. The production process of flue-cured tobacco includes planting, harvesting, curing (baking), and processing, among which the most crucial is the baking process, which determines the color, aroma, and burning characteristics of the tobacco.

[0003] In the prior art, during the process of flue-cured tobacco planting, a small transplanting machine is needed to plant flue-cured tobacco seedlings. Since the growth areas of flue-cured tobacco seedlings are different in each block during transplanting, their growth lengths are different. It may be due to untimely transplanting that when transplanting flue-cured tobacco seedlings, their lengths are relatively long, and the depth of the pits dug by the small transplanting machine is relatively shallow, resulting in a relatively long length of the flue-cured tobacco seedlings exposed above the soil. When windy weather occurs, since the roots and stems of the flue-cured tobacco seedlings have not been fully inserted into the soil, it may lead to the situation that the flue-cured tobacco seedlings are blown away by the wind, thus affecting the normal growth of the flue-cured tobacco seedlings. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem existing in the prior art that during the process of flue-cured tobacco planting, a small transplanting machine is needed to plant flue-cured tobacco seedlings. Since the growth areas of flue-cured tobacco seedlings are different in each block during transplanting, their growth lengths are different. It may be due to untimely transplanting that when transplanting flue-cured tobacco seedlings, their lengths are relatively long, and the depth of the pits dug by the small transplanting machine is relatively shallow, resulting in a relatively long length of the flue-cured tobacco seedlings exposed above the soil. When windy weather occurs, since the roots and stems of the flue-cured tobacco seedlings have not been fully inserted into the soil, it may lead to the situation that the flue-cured tobacco seedlings are blown away by the wind, thus affecting the normal growth of the flue-cured tobacco seedlings.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A small transplanting machine for flue-cured tobacco planting, comprising: a vehicle body, a square groove is opened at the top of the vehicle body, two circular rods II are fixedly installed on the opposite sides of the inner wall of the square groove, two V-shaped strips are symmetrically and movably sleeved on the outer surface of the circular rod II, a circular rod III is fixedly installed on the opposite sides of the two V-shaped strips near the bottom, a subsoiler is fixedly installed on the outer surface of the circular rod III, a fixed block is fixedly installed at the top of the vehicle body near the circular rod II, a plurality of limiting holes are arranged in a circumferential array on the outer surface of the fixed block, a limiting rod is movably embedded on the opposite sides of the two V-shaped strips near the top, and one end of the limiting rod is movably embedded in one of the limiting holes.

Then, by moving the vehicle body 1, pits with different depths can be dug according to the length of the flue-cured tobacco seedlings, ensuring that the roots and stems of the flue-cured tobacco seedlings are deeply inserted into the soil, thus avoiding the situation that the flue-cured tobacco seedlings are blown away by the wind and further ensuring the normal growth of the flue-cured tobacco seedlings.

[0026] Embodiment 2, as Figures 1 to 4 shown, two opening grooves 102 are symmetrically formed at the top of the vehicle body 1 away from the square groove 101. On the opposite sides of the inner walls of the two opening grooves 102, two second guide rods 209 are symmetrically and fixedly installed.

A delivery pipe 103 is movably embedded at the top of the vehicle body 1 close to the bidirectional lead screw 201. An installation ring 104 is fixedly sleeved on the outer surface of the delivery pipe 103 close to the top. The top of the delivery pipe 103 is provided with a wide opening, and the bottom of the delivery pipe 103 is provided with a narrow opening. An electric telescopic rod 105 is fixedly installed at the top of the vehicle body 1 close to the delivery pipe 103, and one end of the electric telescopic rod 105 is fixedly installed at one end of the bottom of the installation ring 104.

[0027] In this embodiment, before the vehicle body 1 moves, according to the depth of the pit, by manually rotating the handle 210, the screw rod 204 can be driven to rotate downward, and with the cooperation of the first guide rod 205, the connecting plate 206 can be moved downward, and at the same time, the first guide rod 205 can be slid downward, so that the pushing plate 208 can be adjusted to an appropriate depth. When the vehicle body 1 is moving, the electric telescopic rod 105 is controlled by the controller to contract, so that the mounting ring 104 is driven to move downward, and at the same time, the conveying pipe 103 is driven to be inserted into the excavated pit. Then, the flue-cured tobacco seedlings are placed in the conveying pipe 103 and slide downward into the pit. At this time, the flue-cured tobacco seedlings are in an upright state under the support of the conveying pipe 103. Then, the motor 202 is controlled by the controller to start, and its output shaft drives the bidirectional screw rod 201 to rotate. Then, under the action of the threaded cooperation between the bidirectional screw rod 201 and the L-shaped threaded bar 203, and with the cooperation of the second guide rod 209 to limit the L-shaped threaded bar 203, the L-shaped threaded bar 203 can move toward the middle along the outer surface of the bidirectional screw rod 201.

At this time, the electric telescopic rod 105 is controlled by the controller to start and extend, pushing the mounting ring 104 and the conveying pipe 103 to move upward, so that the conveying pipe 103 is separated from the flue-cured tobacco seedlings. Then, the vehicle body 1 is moved a certain distance, and so on. In this way, it is convenient to bury the flue-cured tobacco seedlings in the soil and realize automatic filling of the pit, thereby improving the efficiency of flue-cured tobacco seedling planting.

[0028] Working principle: When in use, first determine the depth of soil excavation according to the length of flue-cured tobacco seedlings. Pull the limit rod 302 to one side by hand to disengage it from the inside of the limit hole 305, release the limit on the V-shaped strip 301, and simultaneously stretch the compression spring 303. At this time, the V-shaped strip 301 can rotate around the outer surface of the round rod two 3, and with the cooperation of the round rod three 306, the soil-breaking plow 307 moves downward and inserts into the soil. When the soil-breaking plow 307 is inserted to an appropriate depth, release the limit rod 302, and it inserts into the inside of the limit hole 305 under the reset force of the compression spring 303 to achieve the limit on the V-shaped strip 301. Then, by moving the vehicle body 1, pits with different depths can be excavated according to the length of flue-cured tobacco seedlings, ensuring that the roots and stems of flue-cured tobacco seedlings are deeply inserted into the soil, thus avoiding the situation of flue-cured tobacco seedlings being blown away by the wind and ensuring the normal growth of flue-cured tobacco seedlings. Before the vehicle body 1 moves, according to the depth of the pit, turn the handle 210 by hand to drive the screw rod 204 to rotate downward. With the cooperation of the guide rod one 205, the connecting plate 206 can move downward, and simultaneously the guide rod one 205 slides downward to adjust the push plate 208 to an appropriate depth. When the vehicle body 1 is moving, control the electric telescopic rod 105 to contract through the controller, drive the mounting ring 104 to move downward, and simultaneously drive the delivery pipe 103 to insert into the excavated pit. Then put the flue-cured tobacco seedlings into the delivery pipe 103, and let them slide downward and fall into the pit. At this time, the flue-cured tobacco seedlings are in a straightened state under the support of the delivery pipe 103. Then control the motor 202 to start through the controller, drive its output shaft to drive the bidirectional screw rod 201 to rotate. Then, under the action of the threaded fit between the bidirectional screw rod 201 and the L-shaped threaded strip 203, and with the cooperation of the guide rod two 209 to limit the L-shaped threaded strip 203, the L-shaped threaded strip 203 can move toward the middle along the outer surface of the bidirectional screw rod 201. With the cooperation of the screw rod 204, the guide rod one 205, the connecting plate 206, and the round rod one 207, the push plate 208 can be driven to move toward the middle, push the soil toward the middle, fill the pit with soil, and bury the roots and stems of the flue-cured tobacco seedlings in the soil. At this time, control the electric telescopic rod 105 to start through the controller, make it extend, push the mounting ring 104 and the delivery pipe 103 to move upward, and make the delivery pipe 103 disengage from the flue-cured tobacco seedlings. Then move the vehicle body 1 a certain distance, and repeat this process. In this way, it is convenient to bury the flue-cured tobacco seedlings in the soil and achieve automatic pit filling, thereby improving the planting efficiency of flue-cured tobacco seedlings.
