Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment, specifically a rotary tillage device for rapid return of cotton stalks to the field with adjustable depth. Background Technology

[0002] Cotton is an important economic crop in my country, and the efficient treatment of the large amount of straw left after harvest (usually as high as 3-5 tons / hectare) has always been a challenge in agricultural production. Traditional burning methods have been banned due to environmental pollution and soil carbon loss, while mechanized straw return to the field has become the currently promoted green treatment technology due to its advantages such as improving soil organic matter, improving structure, and reducing soil erosion.

[0003] Existing rotary tillage devices often fail to effectively gather scattered straw in the field into the chopping area when chopping cotton stalks, resulting in low efficiency in the chopping process and uneven straw chopping lengths. This not only affects the quality of straw return to the field but may also lead to uneven distribution of straw in the soil, thereby affecting the growth of subsequent crops. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rotary tillage device for rapid return of cotton stalks to the field with adjustable depth. This solves the problem in the prior art where, when chopping cotton stalks, it is often impossible to effectively gather the scattered stalks in the field into the chopping area, resulting in low efficiency in the chopping process and affecting the quality of straw return to the field.

[0005] A rotary tillage device for rapid return of cotton stalks to the field with adjustable depth includes: a chopping mechanism, including a support assembly, a chopping assembly mounted on the support assembly, a material-aggregating assembly rotatably embedded in the support assembly, and a set of drive assemblies for driving the material-aggregating assembly to rotate;

[0006] The rotary tillage mechanism includes a rotary tillage component that is slidably embedded in the support assembly, and a hydraulic cylinder for driving the rotary tillage component to rise and fall.

[0007] Preferably, the support assembly includes a support frame, a connecting frame is fixedly connected to the support frame, and a set of shaft frames is also fixedly connected to the support frame.

[0008] Preferably, the chopping assembly includes a rotating shaft fixedly connected to the bottom of the support frame via a bearing, a motor is fixedly connected to one end of the rotating shaft, the motor can drive the rotating shaft to rotate, and a plurality of shredding blades are fixedly connected to the outside of the rotating shaft.

[0009] Preferably, the material gathering assembly includes a material gathering shovel rotatably connected to a support frame, and a set of connecting blocks are fixedly connected to the material gathering shovel, each of the connecting blocks having a sliding groove.

[0010] Preferably, a set of drive components includes a hydraulic cylinder rotatably connected to a set of shafts, the output end of the hydraulic cylinder rotatably connected to a traction frame, and the traction frame slidably connected in a slide groove.

[0011] Preferably, the rotary tillage assembly includes an adjusting frame slidably connected to a support frame, a rotary tillage shaft fixedly connected to the bottom of the adjusting frame via a bearing, a second motor fixedly connected to one end of the rotary tillage shaft, the second motor driving the rotary tillage shaft to rotate, a plurality of rotary tillage blades fixedly connected to the outside of the rotary tillage shaft, one end of a second hydraulic cylinder fixedly connected to the support frame, and the other end of the second hydraulic cylinder fixedly connected to the adjusting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model effectively gathers scattered cotton stalks in the field to the vicinity of the crushing blade using a material-gathering shovel, ensuring that the stalks can enter the crushing area evenly, greatly improving the crushing efficiency and avoiding the problems of stalk accumulation or uneven distribution. The hydraulic cylinder adjusts the angle of the material-gathering shovel by sliding the traction frame in the chute, so that it can flexibly adjust the gathering force and range according to the distribution of stalks and operational needs, adapting to cotton stalks of different densities and lodging degrees, thus enhancing the versatility and adaptability of the device.

[0014] 2. This utility model starts the second motor, which causes the rotary tiller shaft to rotate at high speed, starting the tilling operation on the soil. The adjusting frame is kept at the set depth position under the action of the second hydraulic cylinder, ensuring that the rotary tiller can cut the soil evenly and fully mix the chopped cotton stalks into the soil, increasing the organic matter content in the soil, promoting the activity of soil microorganisms, accelerating the decomposition of straw and the conversion of nutrients, and creating good soil conditions for the growth of subsequent crops.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown:

[0022] Example 1: This utility model provides a cotton stalk rapid return-to-field rotary tillage device with adjustable depth, including: a chopping mechanism 1, including a support component 11, a chopping component 12 installed on the support component 11, a material gathering component 13 rotatably embedded on the support component 11, and a set of driving components 14 for driving the material gathering component 13 to rotate.

[0023] The rotary tillage mechanism 2 includes a rotary tillage component 21 that is slidably embedded in the support component 11, and a hydraulic cylinder 22 for driving the rotary tillage component 21 to rise and fall.

[0024] Specifically, the support assembly 11 includes a support frame 111, a connecting frame 112 fixedly connected to the support frame 111, and a set of shaft frames 113 fixedly connected to the support frame 111.

[0025] Specifically, the chopping assembly 12 includes a rotating shaft 121 fixedly connected to the bottom of the support frame 111 via a bearing. One end of the rotating shaft 121 is fixedly connected to a motor, which can drive the rotating shaft 121 to rotate. Several shredding blades 122 are fixedly connected to the outside of the rotating shaft 121.

[0026] Specifically, the material gathering assembly 13 includes a material gathering shovel 131 rotatably connected to the support frame 111. A set of connecting blocks 132 are fixedly connected to the material gathering shovel 131, and each set of connecting blocks 132 is provided with a sliding groove 133.

[0027] Specifically, a set of drive components 14 includes a hydraulic cylinder 141 rotatably connected to a set of shafts 113. The output end of the hydraulic cylinder 141 is fixedly connected to a traction frame 142, which is slidably connected in a slide groove 133.

[0028] As can be seen from the above, during use, the entire rotary tiller is securely connected to the drive vehicle via the connecting frame 112, ensuring that the device can stably follow the drive vehicle during operation. Then, the motor is started, causing the rotating shaft 121 to rotate at high speed, driving the shredder 122 to chop the cotton stalks. Simultaneously, the gathering shovel 131 rotates under the drive assembly 14, effectively gathering the scattered cotton stalks in the field near the shredder 122, ensuring that the stalks enter the chopping area evenly, greatly improving chopping efficiency, avoiding the problem of stalk accumulation or uneven distribution, and ensuring the high efficiency and continuity of the chopping process. Hydraulic cylinder 14... 1. By sliding the traction frame 142 in the chute 133, the angle of the material-gathering shovel 131 can be adjusted, allowing it to flexibly adjust the gathering force and range according to the distribution of straw and operational needs. This adapts to cotton straw of different densities and lodging degrees, enhancing the versatility and adaptability of the device. By controlling the extension and retraction of the hydraulic cylinder 22, the lifting and lowering of the rotary tillage component 21 can be adjusted, enabling operators to flexibly respond to different soil conditions and straw return requirements in different fields. This ensures that the cotton straw is fully mixed into the soil, which is beneficial for soil improvement and nutrient release. At the same time, it avoids the problem of poor operational results caused by excessively deep or shallow rotary tillage, thus improving operational quality and efficiency.

[0029] Example 2: This example is basically the same as the previous example, except that the rotary tillage assembly 21 includes an adjustment frame 211 slidably connected to the support frame 111. The bottom of the adjustment frame 211 is fixedly connected to the rotary tillage shaft 212 via a bearing. One end of the rotary tillage shaft 212 is fixedly connected to a second motor, which can drive the rotary tillage shaft 212 to rotate. Several rotary tillage blades 213 are fixedly connected to the outside of the rotary tillage shaft 212. One end of the second hydraulic cylinder 22 is fixedly connected to the support frame 111, and the other end of the second hydraulic cylinder 22 is fixedly connected to the adjustment frame 211.

[0030] As can be seen from the above, after starting motor 2, rotary tillage shaft 212 drives rotary tillage blade 213 to rotate at high speed, and begins to till the soil. Adjustment frame 211 is kept at the set depth position under the action of hydraulic cylinder 22, ensuring that rotary tillage blade 213 can cut the soil evenly and fully mix the chopped cotton stalks into the soil, increase the organic matter content in the soil, promote the activity of soil microorganisms, accelerate the decomposition of straw and the conversion of nutrients, and create good soil conditions for the growth of subsequent crops.
