Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a multi-shaft straw deep-injection and returning machine. Background Technology

[0002] In agricultural production, to ensure the sustainable use of land, straw is usually returned to the field to increase the organic matter content of the soil. Straw contains a large amount of fresh organic material, which, after being returned to the farmland, can be converted into organic matter and readily available nutrients through a period of decomposition. This not only improves the physical and chemical properties of the soil but also supplies certain nutrients such as potassium. Existing straw from wheat, corn, and other crops is harvested by combine harvesters during harvesting. Straw left on the surface is further crushed by the shovel roller on agricultural machinery and left on the surface. Straw after deep plowing has advantages over straw on the surface in terms of decomposition and retention in the soil. Therefore, some plots need to be deep plowed a second time after being crushed by the shovel roller. The straw particles crushed by the shovel roller are of uneven size, and the large particles decompose slowly after deep plowing. Moreover, the secondary operation affects the efficiency of returning straw to the field. Utility Model Content

[0021] like Figure 1 - Figure 5 As shown, a multi-shaft straw deep-injection returning machine includes a protective cover 1, an external transmission assembly 2, and a retarder 3. The retarder 3 is installed on the top of the protective cover 1, and the external transmission assembly 2 is installed on the side of the protective cover 1. The output shaft of the retarder 3 is connected to the external transmission assembly 2, thereby driving multiple shafts inside the protective cover 1 to rotate.

[0022] The protective cover 1 is equipped with a V-shaped conveying and crushing assembly. The conveying and crushing assembly is provided with a knife roller 8 and a deep tillage roller 10 on both sides. The knife roller 8 is located at the wide opening of the conveying and crushing assembly. The knife roller 8 and the deep tillage roller 10 are common deep tillage and surface straw crushing mechanisms on existing agricultural machinery, which will not be described in detail here.

[0023] The conveying and crushing assembly includes an upper crushing frame 4 and a lower crushing frame 5. Several pneumatic crushing rollers 9 are rotatably mounted on both the upper crushing frame 4 and the lower crushing frame 5. The pneumatic crushing rollers 9 on the upper crushing frame 4 and the lower crushing frame 5 are distributed in a V-shape, thereby realizing the V-shaped setting of the conveying and crushing assembly.

[0024] An upper conveying and crushing drive assembly 7 is installed on the upper crushing frame 4 to facilitate the linkage of several pneumatic crushing rollers 9 on the upper crushing frame 4. A lower conveying and crushing drive assembly 6 is installed on the lower crushing frame 5 to facilitate the linkage of several pneumatic crushing rollers 9 on the lower crushing frame 5, and the rotation direction is opposite to that of the pneumatic crushing rollers 9 on the upper crushing frame 4.

[0025] like Figure 1 - Figure 5 As shown, this utility model also discloses the following more optimized specific structures:

[0026] The pneumatic crushing roller 9 includes a rotating drum 92. The rotating drum 92 has several evenly distributed air grooves 93 on its surface. Several crushing teeth 94 are installed on the rotating drum 92. The crushing teeth 94 are located outside the air grooves 93 and are mainly used for secondary crushing of straw to facilitate subsequent deep plowing and returning to the field. Crushing roller shafts 91 are installed at both ends of the rotating drum 92.

[0027] The lower conveyor crushing transmission assembly 6 includes a lower transmission cover 61, which contains several sets of lower belt assemblies 62. The crushing roller shafts 91 of two adjacent pneumatic crushing rollers 9 on the lower crushing frame 5 are connected by the lower belt assemblies 62. A gear cover 65 is installed on the outside of the lower transmission cover 61. Two meshing gears 63 are provided inside the gear cover 65. A lower drive shaft 64 is rotatably mounted on the gear cover 65. The lower drive shaft 64 is fixedly connected to one gear 63, and the other gear 63 is connected to any crushing roller shaft 91 inside the lower transmission cover 61.

[0028] The upper conveying crushing transmission assembly 7 includes an upper transmission cover 71, which contains several sets of upper belt groups 72. The crushing roller shafts 91 of two adjacent pneumatic crushing rollers 9 on the upper crushing frame 4 are connected by the upper belt groups 72. An upper drive shaft 73 is rotatably mounted on the upper transmission cover 71 and is connected to any crushing roller shaft 91 inside the upper transmission cover 71.

[0029] The retarder 3 has a retarding input shaft 11 connected to a power transmission shaft 13 via a universal joint 12.

[0030] The external transmission assembly 2 includes an external transmission cover and several sets of external transmission belts disposed within the external transmission cover. The upper drive shaft 73, the lower transmission shaft 63, the sling roller shaft, and the deep tillage roller shaft are all connected to the slow output shaft through the external transmission belts to realize the driving of each shaft assembly. As a common transmission structure in the machinery industry, belt drive will not be further described here.

[0031] like Figure 1 - Figure 5 The multi-shaft straw deep-injection and returning machine shown is mainly used in farmland after harvesting corn, wheat, etc. The remaining straw on the ground is dug and crushed by the shovel roller 8. The straw and soil after the initial crushing enter the conveying and crushing assembly with a V-shape. Due to its V-shaped structure, the channel gradually narrows. Small particles are output under the airflow conveying of the pneumatic crushing roller 9 and the multi-shaft crushing of the crushing teeth 94. At the same time, they are mixed with the soil after deep plowing by the deep plowing roller 10. Most of the particles are buried deep, realizing deep injection and returning to the field. This is conducive to the complete retention of straw in the soil, increasing the soil organic matter content, eliminating the need for secondary plowing and burying, and improving the efficiency of straw returning to the field.
