Description

Technical Field

[0001] This utility model relates to the field of cotton stalk return technology, and in particular to a cotton stalk return device. Background Technology

[0002] Returning cotton stalks to the field is an important agricultural technique. It not only increases soil organic matter and improves soil structure, but also prevents soil compaction and enhances agricultural sustainability. The effects of returning cotton stalks to the field include: increasing soil organic matter, improving soil structure, making the soil loose, increasing porosity, reducing bulk density, promoting microbial activity and crop root development. Returning stalks to the field has a significant effect on increasing fertilizer and yield, generally increasing yield by 5% to 10%. When returning cotton stalks to the field, a cotton stalk returning device is required.

[0003] However, in practical applications, because cotton stalks are quite hard, most existing methods involve crushing them and placing them directly on the surface. This prevents the crushed stalks from mixing with the deeper soil layers while returning them to the field, thus affecting the subsequent fermentation of the stalks and failing to achieve the effect of improving soil structure. Utility Model Content

[0004] This utility model discloses a cotton stalk returning device, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0042] Reference Figure 3 and Figure 7 In a preferred embodiment, a stop assembly 6 is provided inside the housing 306. The stop assembly 6 includes an annular groove formed on the surface of the connecting rod 309 and a positioning plate 600 sleeved on the surface of the connecting rod 309.

[0043] Working principle: In use, flange 311 is connected to the power transmission shaft on the tractor via a coupling, and the connecting plate 5 connects the device to the tractor's connecting parts. Then, the threaded column 401 is rotated to adjust the support height of the device, thereby adjusting the depth of the device for crushing straw and tilling the soil. Subsequently, the tractor's power transmission shaft drives the transmission rod 307 to rotate, causing the first bevel gear 308 to drive the connecting rod 309 on the second bevel gear 314 to rotate. Then, the second gear 305 drives the third pulley 302 on the first gear 303 to rotate. Subsequently, through the transmission belt 304, the crushing rod 200 and tilling rod 201 on the second pulley 301 and the first pulley 300 respectively rotate. As the tractor propels the device forward... The crushing blades 203 on the crushing rod 200 rotate rapidly to crush the cotton stalks. Then, the soil is tilled by the tilling plate 205 on the tilling rod 201. When the transmission belt 304 needs to be replaced, the cover 312 can be removed, and the sealing door 313 can be opened to loosen the lead screw 601, so that the limiting strip 602 on the lead screw 601 separates from the inner wall of the annular groove on the connecting rod 309. At the same time, the limiting strip 602 enters the inside of the storage groove, and the bottom of the limiting strip 602 is flush with the inner wall of the round hole. At this time, the second gear 305 on the connecting rod 309 can be pulled outward to separate the first gear 303 from the second gear 305. The transmission belt 304 can be removed or installed through the gap between the first gear 303 and the second gear 305.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
