Description
Technical Field
[0001] The utility model belongs to the technical field of straw crushing and returning machines, and particularly relates to a direct-injection type corn straw crushing and deep-burial returning machine. Background Technique
[0002] At present, the main utilization methods of corn straw resources in China are straw returning to the field, feed utilization, and industrialization. Among them, mechanical crushing and returning of straw has the advantages of increasing soil organic matter content, improving soil structure, reducing chemical fertilizer usage, and enhancing soil water storage and moisture retention capacity. It is currently the most widely used and fastest effective way to mass-process surplus straw. Currently, straw returning methods such as shallow rotary mixing, covering and returning, and deep plowing and returning used in China's production have problems such as affecting the quality of subsequent seeding and emergence, being prone to diseases and pests, and "carbon starvation" in deep soil due to the large amount of corn straw returned to the field and excessive surface straw content.
[0003] In the case of straw returning to the field, poor quality of corn straw crushing and spreading will seriously affect the quality of subsequent land preparation, transplanting, and the decomposition rate of straw, resulting in problems such as machine jamming during land preparation, straw floating before transplanting, and seedling floating during transplanting. Therefore, in order to improve the quality of straw returning to the field and reduce the number of times of machine operation in the field, it is of great significance to design a straw crushing and returning land preparation combined operation machine integrating multiple processes such as straw crushing and returning and ploughing. Content of the Utility Model
[0004] The purpose of the utility model is to provide a direct-injection type corn straw crushing and deep-burial returning machine to solve the problems that poor quality of corn straw crushing and spreading will seriously affect the quality of subsequent land preparation, transplanting, and the decomposition rate of straw, resulting in machine jamming during land preparation, straw floating before transplanting, and seedling floating during transplanting as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A direct-injection type corn straw crushing and deep-burial returning machine includes a frame for crushing corn straw and a soil-breaking shovel installed at the bottom of the frame. A crushing fixed roller is fixed inside the frame, and a crushing moving roller is rotatably connected inside the frame. An installation plate is fixed on one outer wall of the frame, and a blower is installed on the surface of the installation plate.
[0006] A conveying pipeline is arranged on one side of the blower. A discharging pipeline is fixed at the bottom of the conveying pipeline. A baffle is fixed on one outer wall of the discharging pipeline, and a ditching shovel is fixed at the bottom of the baffle. A connecting frame is fixed at the bottom of the ditching shovel. A positioning shaft is fixed on one side of the connecting frame, and two ditching discs are movably connected to the outside of the positioning shaft.
[0007] In a further embodiment, a plurality of crushing blades are cross-installed on the outer walls of the crushing fixed roller and the crushing moving roller. A driving box for driving the crushing moving roller is fixed on one outer wall of the frame.
[0008] In a further embodiment, a drive shaft is installed at the output end of the blower, and a plurality of conveying blades are fixed to the outer wall of the drive shaft.
[0009] In a further embodiment, a threaded groove is formed on the outer wall of the positioning shaft, and fixing rings are threadedly connected to the positioning shafts on both sides of the ditching disc.
[0010] In a further embodiment, a feed inlet is formed at the top of the frame, and a feed hopper is fixed in the feed inlet at the top of the frame.
[0011] In a further embodiment, guide wheels are installed on the outer walls on both sides of the frame, a fixing frame is installed on one outer wall of the discharge pipe, and a U-shaped frame fixedly connected to the frame is installed at the bottom of the fixing frame.
[0012] Technical effects and advantages of the present utility model:
[0013] For this direct-injection type corn straw crushing and deep burial returning machine, through the high-speed rotating crushing moving roller, in cooperation with the crushing blades, the straw that has not been effectively picked up and is still on the surface of the ground is re-sucked into the frame due to the pressure generated by the rotation of the crushing moving roller, and is effectively crushed under the combined action of the crushing fixed roller and the crushing moving roller, as well as during multiple collisions with the inner wall of the frame. Through this process, the corn straw can be crushed into sections. Subsequently, the crushed straw is conveyed to the rear conveying blades under the combined action of centrifugal force and air flow. This design effectively solves the problems of missed picking and incomplete crushing;
[0014] The two disc-shaped ditching discs have strong adaptability and can work stably even when the content of weeds in the surface and soil is relatively high. During use, the two disc-shaped ditching discs are not easy to stick with soil and get blocked, and the mixing of soil layers is less. By designing two disc-shaped ditching discs in front of the ditching shovel to pre-ditch and break the soil on the ground to form a V-shaped strip, the shaking of the ditching shovel is restricted, which is beneficial for entering the soil. At the same time, pre-ditching on the surface can reduce power consumption;
[0015] Through the setting of the baffle plate, when the equipment moves, the straw residues and broken soil are scraped flat, and the straw can be evenly distributed on the deep surface. This direct-injection type corn straw crushing and deep burial returning machine has a compact overall mechanical structure and comprehensive functions, and can complete multiple operations such as straw picking and crushing, ditching and soil breaking, straw deep burial, and soil covering and compaction at one time.

DETAILED DESCRIPTION
[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.
[0023] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.
[0024] See also Figures 1-4, the present utility model provides a direct-injection type corn straw crushing and deep burying returning machine, which includes a frame 1 for crushing corn straws and a soil-breaking shovel 2 installed at the bottom of the frame 1. Guide wheels are installed on both outer walls of the frame 1 through bolts. The soil-breaking shovel 2 can initially break the ground and at the same time shovel up the straws on the ground and those buried in the ground, enabling the straws to quickly enter the frame 1. A fixed crushing roller 3 is fixed inside the frame 1, and a rotating crushing roller 4 is rotatably connected inside the frame 1. A plurality of crushing blades 5 are cross-mounted on the outer walls of the fixed crushing roller 3 and the rotating crushing roller 4. A drive box for driving the rotating crushing roller 4 is fixed on one outer wall of the frame 1. The drive box is a prior art, and its structure will not be elaborated here. When the rotating crushing roller 4 rotates at a high speed, a large centrifugal force will be generated, resulting in pressure on the outer shell of the entire frame 1. When the pressure generated by the rotation increases, on the one hand, it makes the straw crushing effect better, and on the other hand, it sucks the straws that have not been effectively picked up and are still on the ground surface back into the outer shell of the frame 1 due to the pressure generated by the rotation of the rotating crushing roller 4. Under the combined action of the fixed crushing roller 3 and the rotating crushing roller 4, and through multiple collisions with the inner wall of the frame 1, the straws are effectively crushed;
[0025] An installation plate is welded on one outer wall of the frame 1, and a blower 6 is installed on the surface of the installation plate through bolts. A drive shaft 7 is installed at the output end of the blower 6, and a plurality of conveying blades 8 are fixed on the outer wall of the drive shaft 7. When the blower 6 rotates, it drives the drive shaft 7 to rotate, thereby driving the plurality of conveying blades 8 to rotate. The crushed straws are pushed by the combined action of the centrifugal force generated by the rotation of the rotating crushing roller 4 and the air flow to the rear conveying blades 8. At the same time, the drive shaft 7 drives the rotating blades to rotate to convey the crushed straws. A feed inlet is opened at the top of the frame 1, and a feed hopper 9 is welded inside the feed inlet at the top of the frame 1. Through the feed hopper 9, it is convenient to mix the ripening agent into the crushed straws;
[0026] On one side of the fan 6, there is a conveying pipeline 10. At the bottom of the conveying pipeline 10, a discharging pipeline 11 is fixed. On the outer wall of one side of the discharging pipeline 11, a baffle 12 is fixed. A plurality of through holes are formed on the surface of the baffle 12, which is convenient for covering soil. And at the bottom of the baffle 12, a ditching shovel 13 is welded. At the bottom of the ditching shovel 13, a connecting frame 14 is fixed. On one side of the connecting frame 14, a positioning shaft 15 is fixed. Two ditching discs 16 are movably connected to the outside of the positioning shaft 15. Thread grooves are formed on the outer wall of the positioning shaft 15. Fixed rings are threadedly connected to the positioning shaft 15 on both sides of the ditching disc 16. The fixed rings on both sides of the ditching disc 16 are closely attached to both sides of the ditching disc 16, which can fix the position of the ditching disc 16. Rotate the fixed ring to adjust the position of the fixed ring so that it is separated from the ditching disc 16. The ditching disc 16 moves on the positioning shaft 15. According to the requirement of the ditching width, adjust the distance between the two ditching discs 16. Then rotate the fixed ring to both sides of the ditching disc 16 and fit it with the ditching disc 16 to fix the position of the ditching disc 16. The two disc-shaped ditching discs 16 have strong adaptability and can work stably even when the content of weeds in the ground and soil is relatively high. During the use process, the two disc-shaped ditching discs 16 are not easy to stick with soil and get blocked, and the mixing of soil layers is less. Design two disc-shaped ditching discs 16 in front of the ditching shovel 13 to pre-ditch and break the soil on the ground to form a V-shaped strip, which restricts the shaking of the ditching shovel 13 and is beneficial for entering the soil. At the same time, pre-ditching on the ground can reduce the power consumption. On the outer wall of one side of the discharging pipeline 11, a fixing frame is installed. And at the bottom of the fixing frame, a U-shaped frame fixedly connected to the frame 1 is installed, which can move axially and radially to adjust the covering width and the distance from the ground.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt the conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.

[0029] Working principle:
[0030] When in use, the direct-injection type corn straw crushing and deep burial returning machine breaks the ground initially with the soil-breaking shovel 2, and at the same time shovels up the ground and the straw that has sunk into the ground and conveys it into the housing of the frame 1. The drive box drives the crushing moving roller 4 to rotate. The crushing blades 5 on the crushing moving roller 4 and the crushing stationary roller 3 can crush the straw. When the crushing moving roller 4 rotates at a high speed, a large centrifugal force will be generated, resulting in pressure on the housing of the entire frame 1. When the pressure generated by the rotation increases, on the one hand, it makes the effect of straw crushing better, and on the other hand, it sucks the straw that has not been effectively picked up and is still on the ground surface back into the housing of the frame 1 due to the pressure generated by the rotation of the crushing moving roller 4. Under the combined action of the crushing stationary roller 3 and the crushing moving roller 4, and through multiple collisions with the inner wall of the frame 1, it is effectively crushed and is conveyed to the rear conveying blade 8 under the combined promotion of the centrifugal force generated by the rotation of the crushing moving roller 4 and the air flow;
[0031] Start the fan 6, drive the drive shaft 7 to rotate, and thus drive multiple conveying blades 8 to rotate to convey the crushed straw. Mix the decomposing agent into the crushed straw through the feed hopper 9. The fan 6 works to blow the conveyed straw debris into the conveying pipeline 10 and discharge it through the discharge pipeline 11. When the equipment moves, two disc-shaped ditching discs 16 pre-ditch and break the ground to form a V-shaped strip, restricting the shaking of the ditching shovel 13. At the same time, the ditching shovel 13 ditches the ground, and the crushed straw debris falls into the ditch. At the same time, the baffle 12 levels the straw residue and the crushed soil, realizing the uniform distribution of the straw on the deep ground surface.
