[0016] Beneficial effects
[0017] I. In this invention, water is sprayed onto the crushed corn stalks using a spraying device to increase the decomposition speed of the corn stalks. The corn stalks are then returned to the field using a crushing and returning device. The crushed corn stalks fall into the discharge device, where a rotating rod drives a crossbar via a pulley. This causes a bevel gear on the crossbar to drive a guide pipe, which in turn rotates the spraying device. The spraying device disperses the falling corn stalks, while water flows through the guide pipe into the spraying device. The nozzles at the bottom of the spraying device spray water mist onto the crushed corn stalks, increasing their moisture content. This creates a favorable environment for microorganisms after the corn stalks are returned to the field, increasing the decomposition speed. The rapid decomposition of the corn stalks by microorganisms increases the organic matter content in the soil, improves soil fertility, and increases crop yield.
[0018] II. In this invention, the relatively tough corn stalks wrapped around the blade shaft are cut by the blade outside the movable plate. When the corn stalks are crushed and returned to the field by the returning device, the two rotating rods rotate relative to each other inside the main body. The rotating rods drive the rotating plate to rotate, and under the action of the spring, the positioning rod moves upward. The positioning rod drives the blade outside the movable plate to cut the corn stalks wrapped around the rotating rod at the opposite position. This cuts the relatively tough corn stalks, prevents the corn stalks from being wrapped too much and affecting the crushing effect of the blades, reduces the power consumption of the motor drive, improves the service life of the motor, and enables the blades to rotate quickly to cut the corn stalks, thereby improving the corn stalk returning effect.

[0034] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.
[0035] Example: Please refer to Figures 1 to 8 As shown:
[0036] This invention provides a corn stalk returning device, comprising: a main body 1, the two sides of the main body 1 having arc-shaped structures, and a bracket installed on the outer side of the main body 1, and a motor installed at one end of the main body 1, and a feeding mechanism 2 installed on the top of the main body 1; the feeding mechanism 2 includes a feeding component 201, and the two sides of the feeding component 201 have inclined structures, and the feeding component 201 is installed on the top of the main body 1; a wetting mechanism 3 is installed below the main body 1, and the wetting mechanism 3 includes a discharge component 301, and the bottom of the discharge component 301 has a conical structure, and the top of the discharge component 301 is connected to the bottom of the main body 1.
[0037] The main body 1 includes: a rotating rod 101, which is cylindrical and rotatably mounted on the inner side of the main body 1. The outer side of the rotating rod 101 has a groove, and one side end of the rotating rod 101 is connected to the output end of a motor at one end of the main body 1. A bevel gear is mounted on the other side end of the rotating rod 101. A drive rod 102, which is cylindrical and has bevel gears mounted at both ends and in the middle. The drive rod 102 is mounted on the other end of the main body 1 via a bearing seat, and the bevel gears at both ends of the drive rod 102 mesh with the bevel gear on the other side end of the rotating rod 101. A carrier plate 103 has blades mounted on its side. The rotating rod 101 is mounted on the outer side of the rotating rod 101, and a positioning groove is provided on the side end of the rotating rod 104. A movable plate 105 is mounted with a blade on its outer side, which is slidably mounted in a groove on the outer side of the rotating rod 101, and the movable plate 105 is located at the side end of the rotating plate 104. A positioning rod 106 is connected to the inner side of the movable plate 105, and its inner end is slidably mounted in a positioning groove on the side end of the rotating plate 104 via a spring. An outer groove 107 is an annular structure and is located on the outer side of the rotating rod 101. The blades on the outer side of the movable plate 105 are slidably installed inside the 7. When the returning-to-field device crushes and returns corn stalks to the field, the motor at one end of the main body 1 drives a rotating rod 101 to rotate inside the main body 1. Then, one end of the rotating rod 101 drives the drive rod 102 to rotate at the other end of the main body 1 through a bevel gear. This causes the bevel gear at the other end of the drive rod 102 to drive another rotating rod 101 to rotate, so that the two rotating rods 101 rotate in opposite directions inside the main body 1. This causes the rotating rods 101 to drive the blades on the carrier plate 103 to crush the corn stalks that have entered the main body 1. At the same time, the rotating rods 101 drive the rotating plate 104 to rotate. When the rotating plate 104 rotates to the middle position between the two rotating rods 101, When the spring acts, the inner end of the positioning rod 106 moves outward in the positioning groove on the side of the rotating plate 104, causing the outer end of the positioning rod 106 to drive the movable plate 105 outward. This causes the blade on the outer side of the movable plate 105 to move along the groove on the rotating rod 101, allowing the blade on the outer side of the movable plate 105 to cut the corn stalks wrapped around the rotating rod 101 in the opposite position. The outer groove 107 provides the cutting position for the blade on the movable plate 105, ensuring that the blade thoroughly crushes the corn stalks. This process cuts even tough corn stalks, preventing excessive corn stalk wrapping from affecting the crushing effect of the blade on the corn stalks, ensuring the motor rotates quickly to provide driving force, and extending the service life of the returning field device.
[0038] In another embodiment, the bracket on the outside of the main body 1 is directly installed on the agricultural tilling equipment, so that the corn stalks crushed by the returning device are directly spread into the soil. The tilling equipment turns the corn stalks into the soil, reducing the workload of personnel to spread the corn stalks again and improving the returning effect of corn stalks.
[0039] The feeding mechanism 2 further includes: a guide plate 202, the bottom of which is rotatably mounted inside the feeding component 201, and multiple guide plates 202 have inclined plates of varying lengths mounted on their tops, and slots on both sides of the guide plate 202; a movable rod 203, which is cylindrical in shape and has protrusions on its outer side, and is slidably mounted inside the feeding component 201, with the protrusions on the outer side of the movable rod 203 slidably mounted in the slots on both sides of the guide plate 202, and connecting plates mounted on the side ends of the two movable rods 203, which are connected to the outer side of the feeding component 201 by springs; and a side plate 204, which is mounted on the two movable rods. The other end of 203; vertical rod 205, the vertical rod 205 has a cylindrical structure, and the vertical rod 205 is installed at the other end of the main body 1 through a bearing seat, and a bevel gear is installed at the bottom of the vertical rod 205, and the bevel gear at the bottom of the vertical rod 205 meshes with the bevel gear at the middle position of the drive rod 102, and a small gear is installed at the top of the vertical rod 205; rotating part 206, the bottom of the rotating part 206 is installed with a connecting rod, a large gear is installed on the connecting rod, and the connecting rod at the bottom of the rotating part 206 is installed on the outside of the main body 1 through a structural component, and the large gear on the connecting rod at the bottom of the rotating part 206 meshes with the small gear at the top of the vertical rod 205, and the side of the rotating part 206 is provided with a threaded hole; push block 207, the bottom of the push block 207 has an arc-shaped structure, and the push A threaded rod is rotatably mounted on the side of block 207. The threaded rod is rotatably mounted in the threaded hole on the side of rotating part 206, and push block 207 is slidably mounted on the side of side plate 204. When crushing and returning corn stalks to the field, the position of push block 207 is adjusted according to the size and hardness of the corn stalks. The threaded rod on the side of push block 207 is rotated in the threaded hole on the side of rotating part 206 to make push block 207 a suitable position. Longer corn stalks are placed in feed part 201. When drive rod 102 rotates, the bevel gear in the middle of drive rod 102 drives vertical rod 205 to rotate at the other end of main body 1, so that the small gear at the top of vertical rod 205 meshes with the large gear on the bottom connecting rod of rotating part 206, and the rotation speed of rotating part 206 is increased. The rotation is relatively slow, causing the rotating part 206 to drive the push block 207 to rotate. The push block 207 pushes the side plate 204 to move, which in turn causes the side plate 204 to drive the two movable rods 203 to move inside the feed part 201. This causes the protrusions on the outside of the movable rods 203 to move in the slots on the guide plate 202. The movable rods 203 drive the guide plate 202 to move to one side, guiding the corn stalks into the body 1. When the push block 207 leaves the side plate 204, the connecting plates at the sides of the two movable rods 203 move under the action of the spring, causing the movable rods 203 to drive the guide plate 202 to return to its original position. The guide plate 202 then moves back and forth, quickly feeding the corn stalks into the body 1 for crushing, thus improving the crushing efficiency of the corn stalks.
[0040] The wetting mechanism 3 further includes: a guide plate 302, which has an arc-shaped structure and is installed on the inner bottom of the discharge component 301; a water pipe 303, which is installed on the inner side of the discharge component 301 and has a connecting flange installed on its side end; a diversion pipe 304, which has a cylindrical structure and is installed on the top of the water pipe 303, and has an opening at the top; and a crossbar 305, which has a through-hole on its outer side and is rotatably mounted on the discharge component. Inside 301, and the side end of the crossbar 305 is connected to the side end of another rotating rod 101 via a pulley, and a bevel gear is installed on the outside of the crossbar 305, and the crossbar 305 also penetrates the interior of the diverter pipe 304, and the opening on the outside of the crossbar 305 is located inside the diverter pipe 304; the guide pipe 306 has a protrusion at its bottom, and the protrusion at the bottom of the guide pipe 306 is rotatably installed in the opening at the top of the diverter pipe 304, and a bevel gear is installed on the outside of the guide pipe 306, and the bevel gear on the outside of the guide pipe 306 is connected to the outside of the crossbar 305. The bevel gears mesh; the spray element 307 has a ring structure, and a nozzle is installed at the bottom of the spray element 307. A connecting pipe is also installed at the bottom of the spray element 307, and the bottom of the connecting pipe is connected to the top of the guide pipe 306. When returning corn stalks to the field after crushing, the side end of the water pipe 303 is connected to an external water pipe. Water flows through the water pipe 303 to each branch pipe 304, and then through the through-hole on the outside of the crossbar 305 to the inside of the guide pipe 306. The water then flows into the spray element 307. The rotating rod 101 rotates... The crossbar 305 is driven to rotate by the pulley, which in turn drives the bevel gear on the outside of the crossbar 305 to drive the bevel gear on the outside of the guide pipe 306. This causes the guide pipe 306 to rotate at the top of the diverter pipe 304. The top of the guide pipe 306 drives the spraying component 307 to rotate, which breaks up the crushed corn stalks. The water mist sprayed from the nozzle at the bottom of the spraying component 307 wets the corn stalks, providing a favorable environment for the decomposition of the corn stalks, accelerating the decomposition of the corn stalks, and improving the effect of returning the corn stalks to the field. The crushed corn stalks are then diverted out through the guide plate 302.
[0041] The specific usage and function of this embodiment: In this invention, when corn stalks are crushed and returned to the field, the position of the push block 207 is first adjusted according to the size and hardness of the corn stalks. The threaded rod on the side of the push block 207 is rotated in the threaded hole on the side of the rotating part 206, causing the push block 207 to be in a suitable position, and the corn stalks are placed in the feed part 201. The bevel gear in the middle of the drive rod 102 drives the vertical rod 205 to rotate. The small gear at the top of the vertical rod 205 meshes with the large gear on the bottom connecting rod of the rotating part 206. The rotating part 206 drives the push block 207 to push the side plate 204 to move. The side plate 204 drives the two movable rods 203 to move, so that the movable rods 203 drive the guide plate 202 to guide the corn stalks into the main body 1. The motor at one end of the main body 1 drives one rotating rod 101 to drive the other rotating rod 101 to rotate in the opposite direction through the drive rod 102, so that the rotating rod 101 drives the load The blades on plate 103 crush the corn stalks, while the rotating rod 101 drives the rotating plate 104 to rotate. Under the action of the spring, the positioning rod 106 pushes the movable plate 105 to move outward, so that the blades on the outside of the movable plate 105 cut the tough corn stalks wrapped around the rotating rod 101 in the opposite position. This prevents too much corn stalks from affecting the crushing effect of the blades. The external water flows through the water pipe 303 into each branch pipe 304. The water then flows through the through-hole on the outside of the crossbar 305 into the guide pipe 306. The water then flows into the spraying component 307. The rotating rod 101 drives the crossbar 305 through the pulley to drive the guide pipe 306 to rotate at the top of the branch pipe 304. The top of the guide pipe 306 drives the spraying component 307 to rotate. The water mist sprayed from the nozzle at the bottom of the spraying component 307 wets the corn stalks, accelerates the decomposition of the corn stalks, and improves the effect of returning the corn stalks to the field.

The method of using the corn stalk crushing and returning device as described in claim 3, characterized in that: The wetting mechanism (3) further includes: a guide pipe (306), the bottom of which is provided with a protrusion, and the protrusion at the bottom of the guide pipe (306) is rotatably installed in the opening at the top of the diverter pipe (304), and a bevel gear is installed on the outside of the guide pipe (306), and the bevel gear on the outside of the guide pipe (306) meshes with the bevel gear on the outside of the crossbar (305); a spraying component (307), which is a ring structure, and a nozzle is installed at the bottom of the spraying component (307), and a connecting pipe is installed at the bottom of the spraying component (307), and the bottom of the connecting pipe is connected to the top of the guide pipe (306).
5. The method of using the corn stalk crushing and returning device as described in any one of claims 1-4, characterized in that: The method of using the corn stalk crushing and returning device is as follows: First, adjust the position of the push block (207) according to the size and hardness of the corn stalks. Rotate the threaded rod on the side of the push block (207) in the threaded hole on the side of the rotating part (206) to drive the push block (207) to a suitable position. Place the corn stalks in the feeding part (201). The bevel gear in the middle of the drive rod (102) drives the vertical rod (205) to rotate. The small gear at the top of the vertical rod (205) meshes and drives the rotating part to rotate. The large gear on the bottom connecting rod of the rotating part (206) drives the push block (207) to push the side plate (204) to move. The side plate (204) drives the two movable rods (203) to move, so that the movable rods (203) drive the guide plate (202) to guide the corn stalks into the main body (1). The motor at one end of the main body (1) drives one rotating rod (101) to drive the other rotating rod (101) to rotate in opposite directions through the drive rod (102), so that the rotating rod (101) 101) The blades on the carrier plate (103) crush the corn stalks, while the rotating rod (101) drives the rotating plate (104) to rotate. Under the action of the spring, the positioning rod (106) pushes the movable plate (105) to move outward, so that the blades on the outside of the movable plate (105) cut the tough corn stalks wrapped around the rotating rod (101) in the opposite position, preventing too much corn stalks from affecting the crushing effect of the blades. The external water flows through the water pipe (3) 03) The water flows into each branch pipe (304), and then flows through the through-hole on the outside of the crossbar (305) into the guide pipe (306). The water then flows into the spraying component (307). The rotating rod (101) drives the crossbar (305) through the belt pulley to drive the guide pipe (306) to rotate at the top of the branch pipe (304). The top of the guide pipe (306) drives the spraying component (307) to rotate. The water mist sprayed from the nozzle at the bottom of the spraying component (307) wets the corn stalks.
