Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and more specifically, to a corn straw pressing, burying and covering soil equipment. Background Art

[0002] Returning straw to the field can increase soil organic matter and improve soil fertility; organic matter can provide nutrients, improve soil structure, and promote microbial activities; however, corn straw may carry pathogens and insect eggs, and if not properly treated, it will exacerbate pests and diseases; when the soil moisture content is poor, returning straw to the field will slow down the decomposition rate and affect crop growth.

[0003] There is a prior integrated stubble-killing, fertilizer-spreading and straw rotary burying machine with the application number CN202210026842.9. In this patent document, a multi-group of knives are used to sequentially dig up, break and rotary bury the root stubbles of corn straw on the ground to achieve straw returning to the field treatment. Specifically: the power is transmitted to the vertical stubble-killing mechanism through the gears of the reducer A and the small gearbox, and the corn root stubbles are pulverized by the stubble-killing mechanism; for the granular fertilizer fertilization part of the fertilizer-spreading mechanism, under the drive of the motor, the stirring combination rotates, and the throwing disc rotates to spray the granular fertilizer onto the ground surface. When the switch of the liquid fertilizer spraying part is opened, under the action of the booster pump, the liquid fertilizer is sprayed onto the ground surface. The rotation of the motor drives the large bevel gear of the multi-directional movement device to rotate, so that the four-bar mechanism reciprocates and the vibrating plate moves in multiple directions. Under the dual anti-blocking effects of the vibrating plate and the brush roller, the powdered fertilizer is scattered onto the ground surface; the reducer A transmits the power to the reducer B through the transmission shaft, and the reducer B transmits the power to the rotary tillage knife shaft through the gears. Through the rotary motion of the rotary tillage knives, the straw and fertilizer on the ground surface are rotary buried into the soil. Through the sprockets A at both ends of the rotary tillage knife shaft and the elastic tooth shaft, the chain and the sprocket B, the power is transmitted to the elastic tooth shaft, and through the rotary motion of the elastic teeth, the straw on the ground surface and in the shallow soil area is pressed into the deeper soil area.

[0004] However, when using the technical solution in the above patent document, during the process of pulverizing the corn root stubbles, the cutter head will collide with the hard soil blocks attached to the root stubbles, which will cause wear to the cutter head and pose a certain safety hazard; in addition, the pulverized corn root stubbles will be irregularly distributed in the ground. Although rotary tillage can mix this part of the debris with the deep soil, it cannot bury all the debris, and there will still be a lot of debris remaining in the shallow layer of the ground surface, providing nutrients for the reproduction of pathogens and insect eggs, resulting in the aggravation of pests and diseases and affecting the health of crops. Even if the soil is compacted by the elastic teeth later, it is impossible to apply only a vertical extrusion force to the straw in the soil. Therefore, the present application provides a corn straw pressing, burying and covering soil equipment. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The corn straw pressing, burying and covering equipment of the present invention example, as the power equipment moves forward, uses a shovel head to shovel up the residual corn straw on the ground surface and make it enter the shovel guide bin; pushes the part of the corn stubble close to the ground surface, so that the corn stubble moves horizontally for a certain distance and is separated from the soil layer, periodically starts two hydraulic cylinders on the cross beam of the power equipment, and shovels the corn stubble separated from the soil layer into the shovel guide bin; controls the continuous operation of the conveyor belt, and conveys the corn straw and corn stubble shoveled by the shovel head to the rear end of the shovel guide bin, and centrally collects them into the crushing bin, so that they are completely separated from the ground surface, avoiding the residual of the crushed straw in the shallow layer of the ground surface later.

[0020] 2. The corn straw pressing, burying and covering equipment of the present invention example, controls the rotation of the screw conveyor shaft, fully mixes the crushed corn straw and corn stubble with the straw degradation bactericide, and at the same time, pushes the mixture to the lower end of the snake-shaped conduit; during this process, the crushed residues of the corn straw and corn stubble are effectively concentrated in the slag collection bin and the snake-shaped conduit, and are injected into the ground through the snake-shaped conduit, preventing the straw debris from remaining in the shallow layer of the ground and becoming the nutrients for the reproduction of germs and insect eggs, avoiding adverse effects on the health of crops, ensuring the normal growth and development process of crops, and ensuring that crops thrive in a relatively healthy environment.

[0021] 3. The corn straw pressing, burying and covering equipment of the present invention example, controls the rotary digging roller to rotate, drives a plurality of rotary digging knives to rotate synchronously, turns and shovels the corn straw and corn stubble, and throws them towards the inner rear side direction of the shovel guide bin, effectively improving the shoveling ability of the shovel head for the corn straw and corn stubble; in addition, it can make the front end of the shovel head shovel up the corn stubble without inserting into the ground, reducing the amount of hard soil blocks being dug up together, increasing the overall use effect of the equipment; there is no need to frequently adjust the vertical position between the overall equipment and the power equipment, and the operation convenience is good.

[0022] 4. The corn straw pressing, burying and covering equipment of the present invention example, an arc-shaped rolling arm is slidably installed at the rear end inside the crushing bin, and a sieve base is connected to the upper side of the bottom of the crushing bin. Controls the arc-shaped rolling arm to move vertically periodically, and uses the arc-shaped rolling arm to roll the corn stubble piled on the sieve base multiple times, so that the hard soil blocks attached to it are separated from the corn stubble. Under the action of the rolling gap that is large at the front and small at the rear, the corn stubble from which the hard soil blocks have been removed is squeezed between multiple crushing cylinders, and finally is crushed under the action of two groups of crushing cylinders; during this process, the heavier hard soil blocks are intercepted by the anti-overflow edge and remain on the top of the sieve base. As the arc-shaped rolling arm continues to roll, the hard soil blocks are crushed into small pieces by the arc-shaped rolling arm and enter the sieve base through the round hole Ⅰ at the top of the sieve base for storage; reducing the direct contact between the crushing parts and the hard soil blocks, preventing the hard soil blocks from wearing the cutter head, maintaining the sharpness and integrity of the cutter head, and prolonging the service life of the crushing cylinder of the equipment.

[0023] 5. The corn straw pressing, burying and soil covering equipment according to the embodiment of the present invention, a plurality of circular holes II are arranged at the rear side of the bottom of the sieve base, and the land preparation horizontal cylinder is communicated with the circular holes II at the bottom of the sieve base through the conduction groove and the connecting pipe; after the hard soil blocks attached to the corn stubbles are rolled into small pieces by the arc surface rolling arm, they enter the sieve base through the circular holes I at the top of the sieve base for storage. These soil blocks with smaller particle sizes enter the land preparation horizontal cylinder through the circular holes II, the connecting pipe and the conduction groove for storage. As the land preparation horizontal cylinder rotates, the soil blocks rub against each other, and the particle size becomes smaller, and is discharged to the ground surface through the perforations on the outer side of the land preparation horizontal cylinder, improving the soil texture and enhancing the soil uniformity.

[0024] 6. The corn straw pressing, burying and soil covering equipment according to the embodiment of the present invention controls the vertical movement of the slag collecting bin, changes the vertical position of the snake-shaped conduit, and adjusts the landfill depth of the mixture of crushed corn straw, corn stubbles and straw degradation bacteria agent, so as to be able to flexibly adapt to and meet the corresponding planting requirements according to the characteristics of different soils, such as soil texture, soil fertility, and water and fertilizer retention capacity of the soil, etc., and for different crop varieties, such as wheat, rice, corn, cotton, rape, and sugarcane and other crops, the adaptation range of the soil environment and the root growth characteristics.

The flange plate 161 is detachably and fixedly connected to the upper side of the bottom of the crushing cylinder 15.

[0056] The power equipment used in this application can use agricultural tractors of models such as John Deere agricultural machinery tractors, Dongfanghong tractors, Zoomlion heavy machinery tractors, wheeled tractors, crawler tractors, and walking tractors. The specific equipment model is adjusted according to the sizes of the crushing bin 11 and the shovel guide bin 21.

[0057] The specific details of using the corn straw pressing, burying and covering soil equipment of this application are as follows:

[0058] I. Preparation before use;

[0059] First, remove the maintenance cover 13, check whether the crushing cylinder 15 in the crushing bin 11 can rotate smoothly, whether there is foreign matter attached between the arc-shaped rolling arm 37 and the sieve base 35, and check whether the transmission belt 24 can run smoothly through the connection between the crushing bin 11 and the shovel guide bin 21.

[0060] After that, start the two hydraulic cylinders on the crossbeam of the power equipment, and adjust the vertical positions of the suspension adjustment seat and the vehicle body connecting frame 113 together, so that the front end of the shovel head 211 is inserted into the shallow layer of the ground, and the lower ends of the snake-shaped conduit 42 and the soil-breaking plow 43 are inserted into the deep layer of the ground.

[0061] II. Shovel up and collect corn straw and corn root stubbles;

[0062] First, start the power equipment, drive the crushing bin 11 and the shovel guide bin 21 to move forward together. The shovel head 211 shovels up the corn straw remaining on the ground surface and makes it enter the shovel guide bin 21; push the part of the corn root stubbles close to the ground surface, so that the corn root stubbles move horizontally for a certain distance and are separated from the soil layer;

[0063] After that, periodically start the two hydraulic cylinders on the crossbeam of the power equipment, shovel the corn root stubbles separated from the soil layer into the shovel guide bin 21. The shoveled-up corn straw and corn root stubbles are piled up in large quantities at the front end of the guiding platform 25 until the upper-layer corn straw and corn root stubbles overlap with the transmission belt 24, and transfer the corn straw and corn root stubbles to the transmission belt 24; during this process, start the rotation driver II 231, control the rotation of the roller 23, drive the transmission belt 24 to run, and convey the corn straw and corn root stubbles shoveled up by the shovel head 211 to the rear end of the shovel guide bin 21, and centrally collect them into the crushing bin 11.

[0064] III. Crush the corn straw and corn root stubbles;

[0065] The corn straw and corn stubble that enter the crushing bin 11 gather towards the front end of the bottom of the crushing bin 11 under the action of gravity, and under the action of multiple guiding plates 17, they concentrate towards the two groups of crushing cylinders 15. Start multiple rotation drivers I 16 to drive the two crushing cylinders 15 in the same group to rotate synchronously and reversely, and carry out crushing treatment on the corn straw and corn stubble. The crushed slag that meets the requirements passes through the sieve holes on the inclined sieve plate 19 and enters the slag collection bin 41, while the unqualified crushed slag slides along the slope of the inclined sieve plate 19 to the two groups of crushing cylinders 15 for re-crushing.

[0066] IV. Mix the straw and the straw degradation microbial agent and inject them into the ground for landfill and soil covering treatment;

[0067] First, open the valve on the material guiding pipe 181; as the power equipment travels, apply a vibrating force to the microbial agent storage tank 18. The straw degradation microbial agent in the microbial agent storage tank 18 enters the slag collection bin 41 through the material guiding pipe 181, so that the straw degradation microbial agent comes into contact with the crushed slag that meets the requirements;

[0068] After that, start the reduction motor II, control the spiral conveyor shaft 44 to rotate, fully mix the crushed corn straw and corn stubble with the straw degradation microbial agent. At the same time, push the mixture towards the lower end of the serpentine conduit 42. Since the lower end of the serpentine conduit 42 is inserted into the deep ground, it can avoid the ground surface and directly apply the mixture underground.

[0069] Finally, under the rolling action of the land leveling cross cylinder 33, carry out soil covering operation on the rear end area of the serpentine conduit 42 to prevent the straw crushed slag that has been applied underground from being directly exposed to the air. Once the straw crushed slag is directly exposed in the air, it is very easy to be blown up under the action of wind and then fly back to the ground surface again.

[0070] In the above step II, a relatively long oblique conveying area is arranged in the middle of the conveyor belt 24, so that the hard soil blocks accidentally carried up by the shovel head 211 can easily slide down smoothly along the oblique conveying area and be discharged through the sand discharge port 214, reducing the amount of direct contact between the hard soil blocks and the crushing components, reducing the wear and damage to the cutter head 151, and extending the service life of the equipment.

[0071] In the above step IV, the earth-breaking plow 43 is located in front of the serpentine conduit 42. As the power equipment moves forward, the earth-breaking plow 43 first plows out a groove for the serpentine conduit 42 to slide on the ground, and pushes the obstacles in front of the serpentine conduit 42 towards the left and right sides of the serpentine conduit 42 to prevent the serpentine conduit 42 from being damaged by foreign object collision.

[0072] Using the above solution of the present application, during the operation of the device, the crushing bin 11 and the slag collection bin 41 are connected to each other, and both are isolated from the outside of the device, forming a closed space environment. In this state, the corn straws and corn stubble residues are effectively concentrated in the slag collection bin 41 and the serpentine conduit 42, and then injected into the ground through the serpentine conduit 42, preventing the straw debris from remaining in the shallow layer of the ground and becoming the nutrients for the reproduction of pathogens and eggs, avoiding adverse effects on the health of the crops, ensuring the normal growth and development process of the crops, and ensuring that the crops thrive in a relatively healthy environment.

[0073] To increase the shoveling ability of the shovel head 211 for corn straws and corn stubbles, as Figure 2 and Figure 6 shown, a rotary drilling roller 22 is rotatably installed inside the shovel head 211. A plurality of rotary drilling knives 221 are fixedly installed on the side of the rotary drilling roller 22. The end of the rotary drilling knife 221 penetrates through the sand discharge port 214 at the front bottom of the shovel guide bin 21 and extends downward to the lower side of the bottom of the shovel guide bin 21. A reduction motor I for driving the rotary drilling roller 22 to rotate is installed on the shovel guide bin 21; starting the reduction motor I, controlling the rotary drilling roller 22 to rotate, driving the plurality of rotary drilling knives 221 to rotate synchronously, turning and shoveling the corn straws and corn stubbles, and throwing them toward the inner rear side of the shovel guide bin 21, effectively improving the shoveling ability of the shovel head 211 for corn straws and corn stubbles; in addition, it can make the front end of the shovel head 211 shovel the corn stubbles without inserting into the ground, reducing the amount of hard soil blocks being dug up together, increasing the overall use effect of the device; there is no need to frequently adjust the vertical position between the whole device and the power device, and the operation convenience is good.

[0074] To increase the transfer stability of the corn straws and corn stubbles, as Figure 6 and Figure 7 shown, a plurality of anti-slip grooves are provided on the outer side surface of the conveyor belt 24. The extending direction of the anti-slip grooves is parallel to the axis direction of the roller 23. A plurality of anti-backflow plates 26 are rotatably installed under the top of the shovel guide bin 21. The width of a single anti-backflow plate 26 corresponds to the size of the corn stubble. The plurality of anti-backflow plates 26 at the same horizontal height rotate independently of each other. The lower end of the anti-backflow plate 26 overlaps with the upper surface of the conveyor belt 24; in the overlapping state, the anti-backflow plate 26 is inclined with respect to the horizontal plane, so that the anti-backflow plate 26 can only rotate upward and turn over, realizing the one-way rotation of the anti-backflow plate 26 and increasing the transfer stability of the corn straws and corn stubbles.

[0075] Embodiment 2:

[0076] The same features as those in Embodiment 1 will not be described in detail. The difference between this embodiment and Embodiment 1 lies in: as Figure 5 and Figure 8As shown, in this embodiment, an arc-shaped rolling arm 37 is slidably installed at the rear end inside the crushing bin 11. The arc-shaped rolling arm 37 is arranged at the lower end of the lifting seat 36. A linear electric cylinder I 38 for driving the lifting seat 36 to move vertically is installed on the crushing bin 11. The upper side of the bottom of the crushing bin 11 is connected with a sieve seat 35. The top of the sieve seat 35 is provided with a plurality of round holes I. The sieve seat 35 is located below the arc-shaped rolling arm 37. The two ends of the sieve seat 35 are respectively abutted against the inner side walls of the crushing bin 11. An anti-overflow edge 353 is integrally formed on the top of the sieve seat 35. A rolling gap is formed between the lower side surface of the arc-shaped rolling arm 37 and the upper side surface of the anti-overflow edge 353, and the rolling gap is larger at the front and smaller at the rear.

[0077] As the periodically operating transmission belt 24 extends tortuously, the corn straws and corn stubbles are transferred between the sieve seat 35 and the arc-shaped rolling arm 37. As Figure 5 shown, under the action of inertia, the heavier corn stubbles are thrown and piled on the upper side of the sieve seat 35 and are intercepted by the anti-overflow edge 353 to prevent them from entering the front end of the crushing bin 11 prematurely; at this time, the arc-shaped rolling arm 37 is in an upward retracted state;

[0078] Subsequently, start the linear electric cylinder I 38, control the arc-shaped rolling arm 37 to move vertically periodically, and use the arc-shaped rolling arm 37 to roll the corn stubbles piled on the sieve seat 35 multiple times to separate the hard soil blocks attached to them. Under the action of the rolling gap that is larger at the front and smaller at the rear, the corn stubbles from which the hard soil blocks have been removed are squeezed between the multiple crushing cylinders 15 and are finally crushed under the action of the two groups of crushing cylinders 15; during this process, the heavier hard soil blocks are intercepted by the anti-overflow edge 353 and remain on the top of the sieve seat 35. As the arc-shaped rolling arm 37 continues to roll, the hard soil blocks are crushed into small pieces by the arc-shaped rolling arm 37 and enter the sieve seat 35 through the round holes I at the top of the sieve seat 35 for storage.

[0079] Using the above scheme of this embodiment, the hard soil blocks attached to the corn stubbles are removed and concentrated in the sieve seat 35, reducing the direct contact between the crushing components and the hard soil blocks, preventing the hard soil blocks from wearing the cutter heads 151, maintaining the sharpness and integrity of the cutter heads 151, and extending the service life of the crushing cylinders 15 of the equipment.

[0080] In order to increase the restricting effect of the corn stubbles on the upper side of the sieve seat 35, as Figure 5 、 Figure 8 and Figure 9As shown, a rotating shaft 371 is fixedly installed on the upper side of the middle part of the arc-shaped rolling arm 37, so that the arc-shaped rolling arm 37 is rotationally connected to the lifting seat 36 through the rotating shaft 371, and a rotating driver III 372 for driving the rotation of the rotating shaft 371 is installed on the outer side of the end of the lifting seat 36; when the rotating driver III 372 is started, the rotation of the rotating shaft 371 is controlled to drive the synchronous rotation of the arc-shaped rolling arm 37, changing the contact position between the lower side surface of the arc-shaped rolling arm 37 and the upper side surface of the sieve seat 35, avoiding the premature detachment of the corn root stubble from the upper side of the sieve seat 35, and ensuring the efficient removal of the hard soil blocks attached to the corn root stubble.

[0081] Embodiment Three:

[0082] The features that are the same as those in Embodiment One will not be described in detail. The different solutions in this embodiment from Embodiment One are as follows: As Figure 3 , Figure 5 , Figure 8 , Figure 11 and Figure 12 shown, in this embodiment, a plurality of circular holes II are provided at the rear side of the bottom of the sieve seat 35, the diameter of the circular hole I is larger than that of the circular hole II, a tail seat 31 is fixedly installed at the lower side of the rear end of the crushing bin 11, a collar 32 is fixedly installed on the tail seat 31, a communicating pipe is provided on the collar 32, the end of the communicating pipe penetrates through the crushing bin 11 and fits against the inner side wall of the crushing bin 11, the soil preparation cross cylinder 33 is rotatably installed in the collar 32, and a plurality of conduction grooves 34 are provided at corresponding positions on the inner side of the collar 32 and the soil preparation cross cylinder 33. The soil preparation cross cylinder 33 is communicated with the circular hole II at the bottom of the sieve seat 35 through the conduction grooves 34 and the communicating pipe.

[0083] After the hard soil blocks attached to the corn root stubble are rolled into small pieces by the arc-shaped rolling arm 37, they enter the sieve seat 35 through the circular hole I at the top of the sieve seat 35 and are stored therein. This part of the soil blocks with smaller particle sizes enter the soil preparation cross cylinder 33 through the circular hole II, the communicating pipe and the conduction grooves 34 and are stored therein. As the soil preparation cross cylinder 33 rotates, the soil blocks rub against each other, and the particle size becomes smaller, and they are discharged to the ground surface through the perforations on the outer side of the soil preparation cross cylinder 33, improving the soil texture and enhancing the uniformity of the soil; among them, since the arc-shaped rolling arm 37 only applies a rolling force to the corn straws and corn root stubbles, it will not damage the main structures of the corn straws and corn root stubbles, effectively preventing the straw debris from remaining on the ground surface after passing through the sieve seat 35 and the crushing cylinder 15.

[0084] In order to enable the soil blocks in the sieve seat 35 to smoothly enter the soil preparation cross cylinder 33, as Figure 5 and Figure 8As shown in the figure, the sieve base 35 is slidably installed in the crushing bin 11. A T-shaped column 351 is fixedly installed at the bottom of the sieve base 35. The T-shaped column 351 penetrates through the bottom of the crushing bin 11 and is slidably connected to the crushing bin 11. The extending direction of the T-shaped column 351 extends obliquely forward and downward along the crushing bin 11, so that during the sliding process of the sieve base 35, the rear side of the bottom of the sieve base 35 is always in contact with the inner wall of the crushing bin 11. A tension spring 352 is sleeved outside the T-shaped column 351, and the two ends of the tension spring 352 are respectively detachably and fixedly connected to the lower side of the bottom of the crushing bin 11 and the end of the T-shaped column 351;

[0085] Under the action of the tension spring 352, the T-shaped column 351 always has a tendency to slide upward, driving the sieve base 35 to rise obliquely upward together, and then moving downward again under the rolling action of the arc-shaped rolling arm 37. By using the reciprocating lifting of the sieve base 35, the soil blocks in the sieve base 35 can smoothly pass through the circular hole II, the connecting pipe and the conduction groove 34 and enter the land preparation cross cylinder 33, avoiding excessive soil blocks inside the sieve base 35 and affecting the continuous operation of the equipment.

[0086] Example Four:

[0087] The features of this example that are the same as those of Example One will not be elaborated here. The different solutions of this example from Example One are as follows: As Figure 2 、 Figure 4 、 Figure 5 and Figure 14 shown in the figure, in this example, a sealing cylinder 45 is fixedly installed on the outer side of the bottom of the slag outlet 111. The slag collection bin 41 is slidably installed inside the sealing cylinder 45. A linear electric cylinder II 46 for driving the slag collection bin 41 to slide is installed outside the crushing bin 11.

[0088] Start the linear electric cylinder II 46, control the vertical movement of the slag collection bin 41, change the vertical position of the snake-shaped conduit 42, and adjust the landfill depth of the mixture of crushed corn straw, corn stubble and straw degradation bacteria agent, so as to be able to flexibly adapt to and meet the corresponding planting requirements according to the characteristics of different soils, such as soil texture, soil fertility and water and fertilizer retention capacity of the soil, and for different crop varieties, such as wheat, rice, corn, cotton, rapeseed and sugarcane and other crops, the adaptation range of the soil environment and the root growth characteristics;

[0089] During this process, the outer side of the slag collection bin 41 is kept in contact with the inner side of the sealing cylinder 45 to maintain the sealing between the crushing bin 11 and the slag collection bin 41, avoiding more debris of crushed corn straw and corn stubble remaining on the shallow surface of the ground, providing nutrients for the reproduction of germs and insect eggs, resulting in the aggravation of pests and diseases and affecting the health of crops.

[0090] Example Five:

[0091] The features of this embodiment that are the same as those of Embodiment 1 will not be described again. The differences between this embodiment and Embodiment 1 are as follows: As Figure 5 and Figure 6 shown, in this embodiment, a plurality of air jet nozzles 27 are arranged on the shovel guide bin 21. The air jet nozzles 27 are located above the rotary drilling roller 22. The exhaust ports at the lower ends of the air jet nozzles 27 extend towards the top of the guide table 25. The other ends of the plurality of air jet nozzles 27 are connected to a compressed air supply device through a multi-way joint and a pipeline. The compressed air supply device is placed on the upper side of the L-shaped frame structure at the front end of the shovel guide bin 21.

[0092] Among them, the compressed air supply device uses a piston air compressor or a screw air compressor or a centrifugal air compressor. Start the compressed air supply device, so that the plurality of air jet nozzles 27 eject high-speed airflows to drive the corn straw at the shovel head 211 to be blown towards the upper side of the guide table 25, so that it can be smoothly moved onto the conveyor belt 24.

[0093] Compared with Embodiment 1, by piling up a large amount of corn straw at the guide table 25 to complete the operation of moving the corn straw to the upper side of the conveyor belt 24, using the above solution of this embodiment, it is possible to process the relatively sparse straws and root stubbles remaining on the ground surface, and reduce the requirement for the moving speed of the shovel guide bin 21. The power equipment can travel at a slow speed, reducing the operating pressure of the rear-end crushing components, optimizing the entire agricultural machinery operation process, and ensuring the long-term continuous and stable operation of the equipment.

[0094] Embodiment Six:

[0095] The features of this embodiment that are the same as those of Embodiment 1 will not be described again. The differences between this embodiment and Embodiment 1 are as follows: As Figure 10 、 Figure 11 and Figure 12 shown, in this embodiment, the microbial agent storage tank 18 is installed in the enclosed area formed between the guide plate 17 at the edge and the inner side of the crushing bin 11; the guide pipe 181 penetrates through the guide plate 17 and extends towards the lower side of the slag outlet 111. End covers 14 are detachably and fixedly installed on the left and right sides of the crushing bin 11 respectively.

[0096] Using the above solution of this embodiment, it is possible to prevent the adhesion of straw debris to the outside of the microbial agent storage tank 18 and affect the cleanliness of the microbial agent storage tank 18. Maintaining its cleanliness helps to perform effective maintenance operations on the microbial agent storage tank 18 subsequently, such as regular inspections, cleaning, microbial agent supplementation, etc.; manually remove the end cover 14, add straw degradation microbial agents to the microbial agent storage tank 18, or disassemble and clean the microbial agent storage tank 18 to ensure the stable operation of the equipment during long-term and high-intensity operations.

[0097] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the present application.

[0098] Except for the technical features described in the specification, the remaining technical features are well-known to those skilled in the art. To highlight the innovative features of the present invention, the remaining technical features are not described herein again.
