Description

Technical Field

[0001] The utility model relates to the technical field of returning straw to fields, in particular to a device for returning straw to fields. Background Art

[0002] Returning straw to the fields is a measure to improve soil fertility and increase production that is widely valued in the world today. It not only eliminates the air pollution caused by straw burning, but also has the effect of increasing fertilizer and yield. Returning straw to the fields can increase soil organic matter, improve soil structure, make the soil loose, increase porosity, reduce capacity, promote microbial activity and the development of crop roots. Returning straw to the fields has a significant effect on increasing fertilizer and yield, generally increasing yield by 5% to 10%. However, if the method is inappropriate, it will also lead to an increase in soil pathogens, aggravated crop diseases and lack of seedlings (dead seedlings) and other adverse phenomena. Therefore, reasonable measures to return straw to the fields can achieve good returning to the fields effects.

[0024] Specifically, when the driving motor 209 is turned on, the transmission between the sprocket 207 and the chain 208 simultaneously drives the two conveying rollers 205 and the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the spiral blade 204 to pick up the straw and transport it to the conveyor belt 206. The conveyor belt 206 transports the straw to the functional box 1, avoiding collection after the straw is crushed, thereby improving the integrated crushing and collection function.

[0025] Two moving wheels 3 are fixedly installed on the front and rear sides of the function box 1. The bottom of the function box 1 is designed to be hollow. A feed port 4 is opened on the left outer surface of the function box 1 and on the top of the two connecting plates 202. A connecting piece 5 is fixedly installed on the right side of the function box 1.

[0026] Specifically, the function box 1 can be driven to move by providing the moving wheels 3 , and the feed port 4 transports the picked-up straw into the function box 1 .

The two crushing rollers 705 are both located at the bottom of the stirring rod 701.

[0031] Specifically, when the servo motor 703 is turned on, the two crushing rollers 705 are driven by the transmission between the gears 706 to crush the straw, and the crushed straw falls directly into the ground, achieving the purpose of use.

[0032] The conveyor belt 206 is designed at one end close to the feed port 4 , the rotating rod 203 is located at the bottom of the conveyor belt 206 , and the ends of the two electric push rods 201 away from the function box 1 are movably connected to the bottom of the connecting plate 202 .

[0033] Specifically, the position of the spiral blade 204 can be adjusted by the electric push rod 201. When in use, the spiral blade 204 is brought into contact with the straw by the electric push rod 201, and the straw is picked up by the rotation of the spiral blade 204. When the device is not in use, the spiral blade 204 can be tilted.

[0034] When implementing, follow these steps:

When the driving motor 209 is turned on, the transmission between the sprocket 207 and the chain 208 simultaneously drives the two conveying rollers 205 and the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the spiral blade 204 to pick up the straw and convey it to the conveyor belt 206. The straw is transported to the functional box 1 through the conveyor belt 206, avoiding the collection of straw between crushing and improving the working efficiency of the device.

[0040] In addition, by setting up the spraying component 6 and the crushing component 7, the straw enters the functional box 1, and the liquid medicine in the liquid medicine chamber 601 is extracted when the water pump 602 is turned on, and is sprayed through the atomizing nozzle 604, so that the straw is in contact with the liquid medicine, which is more conducive to the composting of the straw; then the servo motor 703 drives the two crushing rollers 705 to crush the straw through the transmission between the gears 706, and the crushed straw falls directly into the ground and is used again.
