Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco planting, in particular to a tobacco planting system facilitating adjustment of planting density. BACKGROUND

[0002] Tobacco plants are large and have a three-dimensional distribution in the field. The microclimate conditions of ventilation and light transmission of tobacco growth are significantly different at different planting densities (plant spacing and row spacing), resulting in large differences in tobacco growth and development, yield and quality. Numerous studies have shown that planting density can affect tobacco plant morphology, canopy light conditions, and tillage nutrient distribution, thereby affecting photosynthetic rate, individual development, and population productivity of tobacco plants, and has an important influence on leaf structure, chemical composition, and sensory quality of tobacco leaves. In different tobacco-growing areas, even in the same tobacco-growing area, different planting densities need to be adopted to produce high-yield and high-quality tobacco leaves. Therefore, reasonable planting density is crucial for tobacco yield and quality. With the continuous advancement of agricultural mechanization and modernization, in order to facilitate the adjustment of planting density, domestic or imported transplanters have been used in some tobacco-growing areas in China. However, the imported machinery is very expensive and the structure of the imported equipment is complex, making it difficult to adjust the planting density. So far, there is still a lack of ideal tobacco transplanting machinery that facilitates adjustment of planting density. Therefore, it is urgent to design a tobacco planting system that is simple in structure, low in cost, and facilitates adjustment of planting density.

[0003] A tobacco planting system facilitating adjustment of planting density with publication number CN113853896B includes a top plate, a tobacco seedling storage mechanism installed on the top plate, a hole digging mechanism installed below the top plate, and a moving support mechanism for supporting the top plate. The tobacco seedling storage mechanism includes a rotating disc rotating above the top plate, and a plurality of storage cylinders circumferentially distributed on the rotating disc. The storage cylinders store tobacco seedlings, and a through hole is provided at the corresponding position of the storage cylinder for the passage of tobacco seedlings. A rotating disc motor is installed on the top plate to drive the rotation of the rotating disc. A discharge hole is also provided on the top plate. The rotating disc rotates to make each through hole sequentially communicate with the discharge hole. The hole digging mechanism can dig holes directly below the discharge hole.

[0004] The device can only dig holes and place tobacco seedlings in the holes during tobacco seedling planting, but it cannot cover the tobacco seedlings with soil, causing the tobacco seedlings to fall over. SUMMARY

Figure 3

[0038] ​When the first round rod 102 rotates 180 degrees, it drives the first gear 101 to rotate, and since the second gear 201 is engaged with the first gear 101, the second gear 201 rotates clockwise, and the other second gear 201 rotates counterclockwise. The second gear 201 drives the cam 205 to rotate 180 degrees through the second round rod 204, and the protruding part of the cam 205 extrudes the fourth round rod 209. The fourth round rod 209 drives the second pipe 208 to move downward on the first pipe 207 and stretches the first tension spring 206.

The lower end of the rack 316 is engaged with the second incomplete gear 310,

[0039] The second gear 201 rotates simultaneously to drive the first pulley 202 to rotate, and the first pulley 202 drives the second pulley 304 to rotate through the belt 203. The second pulley 304 drives the first incomplete gear 305 to rotate 180 degrees, and at this time, the toothed part of the first incomplete gear 305 starts to engage with the third gear 303.

[0040] As the first round rod 102 drives the disc 109 to rotate 90 degrees again, the position of the dropping barrel 104 does not change, and the protruding part of the cam 205 still extrudes the fourth round rod 209. The toothed part of the first incomplete gear 305 drives the third gear 303 to rotate 180 degrees, and the third gear 303 drives the second incomplete gear 310 and the second bevel gear 311 to rotate 180 degrees through the fifth round rod 307.

[0041] At this time, since the second pipe 208 is in a downward moving state, the rack 316 is engaged with the second incomplete gear 310, and the rack 316 moves away from the second pipe 208. At this time, the rack 316 drives the conical cover 317, the second fixed plate 318, and the limiting strip 315 to move.

The second fixed plate 318 stretches the second tension spring 314, and the limiting strip 315 engages with the limiting hook 313, so that the rack 316 will not rebound due to the second tension spring 314.

[0042] Since the first bevel gear 309 and the second bevel gear 311 are engaged with each other, the first bevel gear 309 rotates 180 degrees, and the first bevel gear 309 drives the push plate 306 to rotate counterclockwise by 180 degrees (from the perspective of looking from the seat 5 to the battery 1) through the sixth round rod 308. The push plate 306 is inserted into the soil below.

[0043] When the first round rod 102 rotates 90 degrees again, the first cam 205 will no longer press the fourth round rod 209, the first tension spring 206 retracts to the initial position, at this time the second pipe 208 drives the support frame 319 to rise, at this time the limiting hook 313 on the support frame 319 will press the seventh round rod 312, the limiting hook 313 rotates and does not engage with the limiting strip 315, the second tension spring 314 retracts to the initial position, the second tension spring 314 drives the rack 316 to return to the initial position through the second fixed plate 318, at this time the conical cover 317 is closed;

[0044] Subsequently, the round pin 107 moves the sliding rod 106 to one side of the double-shaft motor 108 under the action of the sliding groove 110, the sliding rod 106 drives the planting barrel 104 to move through the support rod 105, the planting barrel 104 is communicated with the through hole 7, the tobacco seedlings fall down, and the infrared counting sensor 111 performs counting once;

[0045] Finally, the toothed part of the first incomplete gear 305 drives the third gear 303 to rotate 180 degrees again, the third gear 303 drives the second incomplete gear 310 and the second bevel gear 311 to rotate 180 degrees through the fifth round rod 307, the second incomplete gear 310 returns to the initial position, the second bevel gear 311 drives the first bevel gear 309 to rotate 180 degrees, the first bevel gear 309 drives the push plate 306 to rotate 180 degrees through the sixth round rod 308, at this time the push plate 306 pushes the soil to the tobacco seedlings, performs hilling, prevents toppling, and repeats the above steps to complete planting, and the planting density can be changed by adjusting the rotation speed of the double-shaft motor 108;

[0046] When the frame 6 moves, the shock absorber 10 can make the wheel 3 suitable for driving on uneven road sections, and the support 11 slides on the frame 6, which makes the wheel 3 drive in a straight line and prevents deviation, when turning is needed, the electric telescopic rod 8 is extended to press the shock absorber 10, the shock absorber 10 drives the wheel 3 to move downward through the support 11, when the support 11 slides out of the frame 6, the wheel 3 can follow the trailer to turn, and when adjustment is made again, the electric telescopic rod 8 is retracted.

[0047] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
