Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a device for deep mixing and returning corn and soybean straw to the field during corn-soybean rotation. Background Technology

[0002] The corn-soybean rotation straw deep mixing and returning device in intelligent agricultural power machinery mainly uses rotating blades to crush corn or soybean straw and deeply mix the straw into the soil tillage layer. This treatment method significantly increases the soil organic matter content, improves the soil aggregate structure, and enhances the soil's water and fertilizer retention capacity.

[0003] Among the existing publicly available documents, patent publication number CN105638002A discloses a strip deep tillage, ridge clearing, and straw mixing combined operation machine. This technology can complete deep tillage, ridge clearing, mixing, and compaction of dryland land and straw return to the field in one operation. It can also achieve deep tillage, clearing of ridges, straw return to the field, soil fertility improvement, and enhancement of soil organic matter, effectively preventing straw burning. However, this technology still has the following problems.

[0004] When corn and soybean rotation straw is deeply mixed into the field, although the straw can be crushed and returned to the field, there are obvious problems. The crushed straw fragments penetrate deep into the soil, while the composting agent is only sprayed on the surface and cannot penetrate into the interior to decompose the straw. This makes it difficult for the composting agent to achieve intelligent and dynamic synchronous diffusion according to the deepest mixing position of the straw during the crushing and returning process. Not only is the straw decomposition accuracy poor and it is difficult to effectively decompose the straw, but it also causes a large amount of composting agent to be wasted. Due to prolonged stay on the surface, it becomes inactive, resulting in poor returning effect and a large amount of returning raw materials. Summary of the Invention

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention, through the linkage control of the detection power component and the straw return supply component, can intelligently and automatically activate the decomposition liquid agent spraying when the cutter and the diversion nozzle rotate to the bottom and enter the deep mixing layer. The decomposition liquid agent can intelligently achieve dynamic synchronous diffusion according to the deepest mixing position of the straw, making the straw return decomposition more precise and effective, and penetrating deep mixing positions, avoiding the waste caused by a large amount of decomposition liquid agent adhering to the soil surface. It realizes intelligent, precise, synchronous, and dynamic supply of decomposition liquid agent to the deep mixing area of ​​the soil, which not only makes the straw return treatment effect of the straw return device better, but also saves a lot of raw materials for straw return decomposition liquid agent.

[0017] 2. This invention utilizes a rotating roller to integrate a cutter and a diversion nozzle, and controls the opening and closing of the diversion nozzle's nozzle through the reciprocating motion of an arc plate and a sealing gasket. When the diversion nozzle reaches a non-deep mixing position, the sealing gasket automatically closes the nozzle under the action of a spring and a spring. It is only triggered by power to open at the set deep mixing position, thus avoiding continuous and ineffective spraying of the composting agent throughout the entire operation process. This fundamentally prevents the composting agent from evaporating, becoming inactive, or being wasted due to prolonged residence on the ground surface, greatly saving the raw materials for returning to the field.

[0018] 3. This invention uses a pre-storage unit to pressurize and pre-store the composting agent in the roller, and with the precise opening of the return-to-field supply unit, the composting agent is directly delivered to the diversion nozzle that rotates with the roller, where it dynamically diffuses within the deep mixed soil layer. This ensures that the composting agent has full and uniform contact with the deeply buried straw fragments, greatly improving the return-to-field effect and effectively promoting the increase of soil organic matter and the formation of aggregate structure. At the same time, the entire mechanical structure is compact, highly automated, and the return-to-field operation is continuous and efficient. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1: like Figure 1 - Figure 9 The device for deep mixing and returning corn and soybean straw to the field, as shown, includes a mounting frame 1, a rotating roller 2 inside the mounting frame 1, and multiple actuating blocks 3 on one side of the roller 2; a detection power component installed at the bottom of the mounting frame 1; a straw return supply component installed on one side of each actuating block 3; multiple split nozzles 4, all fixedly connected to the outer wall of the roller 2, and each split nozzle 4 has a cutter 5 on its outer wall, and the cutter 5 is fixedly connected to the roller 2; a driving component is installed at one end of the roller 2, and a pre-storage component is installed at the other end of the roller 2.

[0032] The operating principle of this embodiment is as follows: the pre-storage unit pressurizes and delivers the composting agent into the roller 2 for storage. The drive unit drives the roller 2 to rotate, and the roller 2 drives the cutter 5 to crush the straw. This can achieve the crushing operation of corn and soybean rotation straw. During crushing, the straw comes into contact with the soil. When the cutter 5 rotates to the bottom of the roller 2 and enters the deep concrete, the detection power unit senses the corresponding trigger block 3. The detection power unit drives the trigger block 3 to move to the right, realizing intelligent positioning. The trigger block 3 then drives the corresponding return-to-field supply unit to open the corresponding diversion nozzle 4, delivering the composting agent in the roller 2 to the diversion nozzle 4 and dynamically spraying it into the deep concrete. The composting agent can intelligently achieve dynamic synchronous diffusion according to the deepest mixing position of the straw. This not only makes the straw return-to-field decomposition more accurate and effectively decomposes the straw, but also penetrates deep into the mixing position, avoiding the waste caused by a large amount of composting agent adhering to the soil surface. This not only improves the return-to-field effect but also saves a lot of raw materials for composting agent.

[0033] Example 2, based on Example 1, discloses a corn-soybean rotation straw deep mixing and returning device.

[0034] In this embodiment, as Figure 2 - Figure 3 As shown, the detection power components include: a proximity sensor 7, fixed to the bottom of the mounting bracket 1; a sensing block 6 is fixed to the upper surface of each actuating block 3, and multiple sensing blocks 6 are arranged in a circumferentially equidistant distribution; an arc-shaped sleeve 8, located below the proximity sensor 7; two ball bearings 9 are rolled on the inner wall of the arc-shaped sleeve 8, and a push rod 10 is fixedly connected to one side of the arc-shaped sleeve 8. One end of the push rod 10 is equipped with an electric cylinder 11, which is fixedly connected to the mounting bracket 1, and the output end of the electric cylinder 11 is fixedly connected to the push rod 10. There is a gap between the two ball bearings 9, and the proximity sensor 7 and the arc-shaped sleeve 8 are slidably connected. The vertical cross-sectional shape of each actuating block 3 is arc-shaped, and multiple actuating blocks 3 are arranged in a circumferential distribution.

[0035] The operating principle of this embodiment is as follows: when the actuating block 3 drives the sensing block 6 to rotate, and the sensing block 6 rotates to the sensing position of the proximity sensor 7, when the proximity sensor 7 senses the sensing block 6, it immediately activates the electric cylinder 11 through the controller 16. The output end of the electric cylinder 11 pushes the push rod 10 to the right, the push rod 10 drives the arc sleeve 8 to the right, and the arc sleeve 8 drives the two balls 9 to the right. The balls 9 press against the left side of the actuating block 3, so that while the actuating block 3 rotates on the balls 9, it can achieve the rightward movement without affecting the normal rotation operation of the actuating block 3. This ensures that the sensing block 6 on the actuating block 3 rotates to the sensing position of the proximity sensor 7, so that the rightward movement force can be accurately provided to the actuating block 3. Furthermore, it ensures that the rightward movement force is provided only when the cutter 5 rotates to the bottom of the roller 2 and enters the deep concrete, and at the same time, the diversion nozzle 4 on the cutter 5 also enters the deep concrete.

[0036] When the actuating block 3 is no longer in contact with the ball 9, the proximity sensor 7 no longer senses the sensing block 6. This causes the starting electric cylinder 11 to move the push rod 10 to the left to reset. The push rod 10 moves the arc sleeve 8 to the left, and the arc sleeve 8 moves the two balls 9 to the left. The balls 9 no longer press against the actuating block 3.

[0037] Example 3, based on Example 2, discloses a corn-soybean rotation straw deep mixing and returning device.

[0038] In this embodiment, as Figure 4 - Figure 7 As shown, the field return supply component includes: a linkage rod 12, fixed to one side of the actuating block 3, the linkage rod 12 being slidably connected to the roller 2, and a pressure ring 13 fixed to one end of the linkage rod 12; an inclined pressure block 14, fixedly installed at one end of the pressure ring 13, an inclined moving block 15 being slidably installed on the upper inclined surface of the inclined pressure block 14, and a groove column 17 being fixed to the outer wall of the inclined moving block 15, the inclined pressure block 14 being used to squeeze the inclined moving block 15 upward; an arc plate 18, fixedly connected to the bottom end of the groove column 17, a sealing gasket 19 being fixed to the outer wall of the arc plate 18, the sealing gasket 19 being in extrusion contact with the inner wall of the roller 2; and a slider 20, fixed to the top end of the groove column 17, a positioning frame 22 being provided on the outer wall of the slider 20, the slider 20 and the groove column 17 being slidably connected to the positioning frame 22, and a spring piece 21 being fixedly installed between the slider 20 and the positioning frame 22, the spring piece 21 being used to provide elastic force to the slider 20.

[0039] A support block 23 is provided on one side of the positioning frame 22, and both the positioning frame 22 and the roller 2 are fixedly connected to the support block 23. Inclined brackets 24 are fixed on both sides of the outer wall of the groove column 17, and the bottom ends of both brackets 24 are fixedly connected to the arc-shaped plate 18. A linkage ring 25 is fixed on the outer wall of the linkage rod 12 near the bracket 24. A spring 26 is fixedly connected to one side of the linkage ring 25, and a sealing ring 27 is fixedly installed at one end of the spring 26. The sealing ring 27 is fixedly connected to the mounting bracket 1, and the linkage rod 12 is slidably connected to the sealing ring 27.

[0040] The operating principle of this embodiment is as follows: when the actuating block 3 rotates and moves to the right, the actuating block 3 will drive the linkage rod 12 to move to the right. The linkage rod 12 moves to the right along the inner wall of the roller 2, and the linkage rod 12 drives the linkage ring 25 to move to the right. The linkage ring 25 pulls the spring 26, and at the same time, the sealing ring 27 supports the spring 26. The linkage rod 12 moves to the right along the inner wall of the sealing ring 27, and the sealing ring 27 provides a sealing treatment for the rightward movement of the linkage rod 12, ensuring that the linkage rod 12 drives the pressure ring 13 to move to the right. The pressure ring 13 causes the inclined pressure block 14 to move to the right. The upper inclined surface of the inclined pressure block 14 presses against the lower inclined surface of the inclined moving block 15, causing the inclined moving block 15 to move upward. The inclined moving block 15 drives the groove column 17 to move upward, and the groove column 17 drives the slider 20 to move upward. The groove column 17 is guided upward along the inner wall of the positioning frame 22, thereby the slider 20 presses the spring piece 21. The spring piece 21 is compressed on the positioning frame 22, and the roller 2 supports the support block 23, which supports the positioning frame 22. The positioning frame 22 provides support force to the spring piece 21.

[0041] The groove column 17 drives the two inclined frames 24 to move upward. Both the two inclined frames 24 and the groove column 17 drive the arc plate 18 to move upward. In this way, the arc plate 18 drives the sealing gasket 19 to move upward. The sealing gasket 19 begins to move away from the inner wall of the roller 2. Thus, the sealing gasket 19 no longer seals the connection between the multiple diversion nozzles 4 and the multiple rollers 2, and the multiple diversion nozzles 4 can be opened. In this way, the composting liquid inside the roller 2 is transported to the inside of the diversion nozzles 4, and the composting liquid is sprayed into the deep concrete by the diversion nozzles 4. At this time, the roller 2 continues to drive the multiple diversion nozzles 4 to rotate. In this way, the diversion nozzles 4 can also dynamically spray the composting liquid, ensuring that the composting liquid can be intelligently and dynamically diffused according to the deepest mixing position of the straw.

[0042] When the ball bearing 9 stops pressing the actuating block 3, under the action of the spring plate 21's rebound force, the spring plate 21 drives the slider 20 to move down, the slider 20 drives the groove column 17 to move down, the groove column 17 drives the two inclined frames 24 to move down, the inclined frames 24 and the groove column 17 both drive the arc plate 18 to move down, the arc plate 18 drives the sealing gasket 19 to press against the inner wall of the roller 2, continuing to seal the connection between the diversion nozzle 4 and the roller 2, and under the action of the spring 26's rebound force, the spring 26 causes the linkage ring 25 to move to the left, the linkage ring 25 drives the linkage rod 12 to move to the left, the linkage rod 12 drives the actuating block 3 to move to the left and reset, ensuring that the composting liquid agent only achieves dynamic synchronous diffusion at the deepest mixing position of the straw, avoiding waste.

[0043] Example 4: Based on Example 3, this example discloses a device for deep mixing and returning corn and soybean straw to the field during crop rotation.

[0044] In this embodiment, as Figure 8 As shown, the pre-storage component includes: a supply pipe 28 connected to the other end of the roller 2, and a manual valve 29 threadedly connected to one end of the supply pipe 28.

[0045] The principle of this embodiment is to use a pressure machine to pressurize and deliver the curing agent to the manual valve 29. After opening the manual valve 29, the curing agent is delivered to the supply pipe 28 and poured into the roller 2 for pre-storage by the supply pipe 28. A certain pressure is formed inside the roller 2, and the agent is then stored for use.

[0046] Example 5, based on Example 4, discloses a corn-soybean rotation straw deep mixing and returning device.

[0047] In this embodiment, as Figure 1 - Figure 9 As shown, the driving component includes a motor 30, which is disposed at one end of the roller 2 and is used to drive the roller 2 to rotate. The outer wall of the motor 30 is fixedly connected to the mounting frame 1. A controller 16 is installed at one end of the mounting frame 1 and is electrically connected to the motor 30.

[0048] The principle of this embodiment is that the mounting frame 1 is fixed to the traction frame of the agricultural tractor with bolts. The tractor can move the mounting frame 1 in the field. At the same time, the controller 16 can start the motor 30. The mounting frame 1 provides support to the outer wall of the motor 30. The output end of the motor 30 drives the roller 2 to rotate. The roller 2 drives multiple cutters 5 to rotate, which can crush the corn and soybean rotation straw and rotate and mix the soil. The roller 2 can also drive the diversion nozzle 4 into the deep mixing position area.
