Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and specifically to an equipment for returning livestock manure and crop straw to the field. Background Art

[0002] A straw returning equipment is a kind of conservation tillage machinery that cuts and crushes the straw stubbles remaining in the field and then spreads or buries them in the soil. Most of the current straw returning equipment is aimed at crop straws such as corn straw and rice straw. Its treatment method is to cut and turn the straw into the soil by plowing so that it rots and decomposes, and mix livestock manure or a preparation for improving the soil acidity and alkalinity into the soil, so as to achieve the purpose of fertilizing and improving the land in the straw returning stage. When operating, the high-speed rotating cutter, hammer claw or flail knife cuts the straw, picks up the stubbles, and inputs them into the casing. After being repeatedly sheared, rubbed and torn by the fixed and moving knives and crushed, they are evenly scattered in the field and then plowed into the soil immediately to rot and decompose as base fertilizer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This kind of livestock manure and crop straw returning to the field processing equipment, by setting a baffle slider through the friction and squeezing with the manure, promotes the full mixing and stirring of undigested feed residues and other ingredients, and drives the manure and residues to form a complex flow field through the rotating frame to make the mixing more uniform and thorough, and the grille limits the outflow of manure, prevents large-sized undigested feed residues and fibrous materials that are easy to entangle the agitator blades to prevent the blades from being entangled, thereby ensuring the stable operation and processing efficiency of the equipment, and limits the angle of the crop straw being rotated into the soil by the rotary tillage device through the double-sided baffles, so that when returning it to the field, the livestock manure and crop straw will not be thrown out of the limited position after rotary tillage, thereby ensuring the returning effect.

[0017] 2. This livestock manure and crop straw returning equipment limits the manure inflow by adjusting the position of the second arc-shaped baffle. When restricting the flow rate, the feeding hole can still ensure the stable entry of the minimum amount of manure, balancing the processing efficiency and equipment stability, and preventing failures and process interruptions caused by overload or interrupted flow. At the same time, the third arc-shaped baffle protects the I-shaped slider, effectively resisting potential impacts such as sharp foreign objects, large solid particles in the manure, and equipment operation vibrations, ensuring the good operation state of the I-shaped slider, and preventing the outflow of livestock manure from causing soil compaction on the surface of the rotary tillage device, ensuring the effect of crop straw returning to the field.

[0018] 3. This livestock manure and crop straw returning equipment collaborates with the flow-limiting mechanism through the rotation of the rotating plate. The rotating plate adjusts the blocking degree to control the outflow volume, and removes the attached foreign objects during rotation to ensure smooth rotation and continuous function. Moreover, the rotating plate provides support for the horizontal grid, disperses the load, resists the impact pressure, improves the stability and durability of the horizontal grid, extends its service life, reduces the maintenance and replacement costs, and ensures the long-term stable and efficient operation of the processing system.

[0019] 4. The vertical grid of this livestock manure and crop straw returning equipment will be blocked by the attached manure, affecting its function and causing a reduction or interruption in the efficiency of the processing process. The second scraper rotates and scrapes effectively in contact with the surface of the vertical grid to ensure the peeling of manure without damaging the vertical grid. Its material is wear-resistant and corrosion-resistant, adapting to harsh environments, and stably performing functions such as filtering, screening, and guiding, ensuring the efficient and stable operation of the processing equipment.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: a livestock manure and crop straw returning treatment device, including a mixing tank 1, a motor 2 is fixedly connected to the outer surface of the mixing tank 1, a spreading device 4 is fixedly connected to the lower surface of the mixing tank 1, a rotary tillage device 5 is fixedly connected to the lower surface of the spreading device 4, double-sided baffles 7 are fixedly connected to the outer surface of the rotary tillage device 5, a feeding trough 8 is fixedly connected to the upper surface of the mixing tank 1, a mixing mechanism 3 and a flow limiting mechanism 6 are rotatably connected inside the mixing tank 1, an adjusting mechanism 9 is fixedly connected to the inner wall of the mixing tank 1, and further includes:

[0042] The mixing mechanism 3 includes a first rotating rod 301, the first rotating rod 301 is rotatably connected to the inner wall of the mixing tank 1, a fixed collar 302 is fixedly connected to the outer surface of the first rotating rod 301, an arc-shaped through-hole column 303 is fixedly connected to the outer surface of the fixed collar 302, a first sliding rod 308 is fixedly connected to the outer surface of the arc-shaped through-hole column 303, a baffle slider 306 is inserted on the outer surface of the first sliding rod 308, a first scraper 307 is fixedly connected to the top of the baffle slider 306, a first spring 305 is fixedly connected to the lower surface of the baffle slider 306, a first telescopic baffle 304 is fixedly connected to the outer surface of the arc-shaped through-hole column 303, and the baffle slider 306 is used for stirring livestock manure.

[0043] The mixing mechanism 3 further includes a rotating collar 309, the rotating collar 309 is rotatably connected to the outer surface of the first rotating rod 301, a second rotating rod 310 is fixedly connected to the outer surface of the rotating collar 309, a rotating frame 311 is rotatably connected to the outer surface of the second rotating rod 310, an arc-shaped baffle 312 is fixedly connected to the top of the inner wall of the mixing tank 1, a horizontal grid 313 and a vertical grid 314 are fixedly connected to the bottom of the inner wall of the mixing tank 1, and the arc-shaped baffle 312 is used for restricting the flow of livestock manure.

[0044] The outer surface of the first rotating rod 301 is fixedly connected to the output end of the motor 2. The first telescopic baffle 304 is in contact with the outer surface of the baffle slider 306. The bottom of the first spring 305 is fixedly connected to the outer surface of the arc-shaped through-hole slider. The outer surface of the first scraper 307 is in contact with the lower surface of the first arc-shaped baffle 312. The first scraper 307 is used to clean the surfaces of the first arc-shaped baffle 312 and the horizontal grille 313. The distance from the fixed collar 302 to the mixing tank 1 is the same as the distance from the fixed collar 302 to the rotating collar 309. The outer surface of the second rotating rod 310 is fixedly connected to the inner wall of the mixing tank 1. The outer surface of the baffle slider 306 is not in contact with the rotating cylinder of the rotating frame 311. The rotating frame 311 is used to stir livestock manure. Replace the spiral stirring paddle with the baffle slider 306 and the rotating frame 311. When undigested feed residues in livestock manure wind around its surface, the movement of the baffle slider 306 and the rotation of the rotating frame 311 prevent it from winding, reducing the impact on the stirring efficiency, and in this way, the motor 2 is protected from damage caused by the winding of fibrous impurities in the flow field. While the baffle slider 306 rotates and pushes the rotating frame 311 to rotate around the second rotating rod 310, the length of the baffle slider 306 allows it not to block its own rotation when pushing the rotating frame 311. When not stirring livestock manure, the motor 2 drives the baffle slider 306 to rotate and drives the first scraper 307 to rotate to scrape and clean the lower surface of the first arc-shaped baffle 312 and the horizontal grille 313.

[0045] The working principle of this embodiment is as follows: When using this livestock manure and crop straw returning equipment, after putting livestock manure into the feeding trough 8, through the guiding and diversion of the first arc-shaped baffle 312, the livestock manure enters through both sides of the first arc-shaped baffle 312 and is stirred. At this time, the motor 2 starts to rotate, driving the first rotating rod 301 to rotate. The first rotating rod 301 drives the fixed collar 302 to rotate, and drives the baffle slider 306 to rotate through the first sliding rod 308. At this time, the first spring 305 supports and pushes the baffle slider 306 to stay at the top of the arc-shaped through-hole column 303. While the baffle slider 306 rotates, it cooperates with the other baffle sliders 306 to stir the livestock manure. While rotating, when the baffle slider 306 contacts the outer surface of the rotating frame 311, it pushes the rotating frame 311 to rotate around the outer surface of the second rotating rod 310 to assist in stirring the livestock manure. When fibrous impurities are easily wound around the surface of the baffle slider 306 under the flow field, the baffle slider 306 is stressed and slides on the outer surface of the first sliding rod 308 to loosen the winding and reduce the stress, and tears the fibrous impurities through the rotating frame 311 and cooperates with each other so that they will not be wound. After being stirred inside the stirring tank 1, it enters the spreading device 4 for diversion through the horizontal grid 313 and the vertical grid 314, and is discharged through the rotary tillage of the rotary tillage device 5, and is jointly rotated into the field with the crop straw to realize the returning treatment of livestock manure and crop straw to the field.

[0046] Embodiment 2: Please refer to Figures 6 - 9 , on the basis of Embodiment 1, the present invention provides a technical solution: The flow-limiting mechanism 6 includes a first screw rod 601, the first screw rod 601 is rotatably connected to the inner wall of the first box body, the outer surface of the first screw rod 601 is threadedly connected with an I-shaped slider 602, the inside of the I-shaped slider 602 is inserted with a second sliding rod 603, the top of the second sliding rod 603 is fixedly connected with a second arc-shaped baffle 604, a feed hole 605 is opened inside the second arc-shaped baffle 604, the lower surface of the second arc-shaped baffle 604 is fixedly connected with a second telescopic baffle 607 and a second spring 606, the outer surface of the second telescopic baffle 607 is fixedly connected with a third arc-shaped baffle 608, and an arc-shaped hole 609 is opened inside the first arc-shaped baffle 312. The second arc-shaped baffle 604 is used to block the feeding trough 8.

[0047] The bottom of the second spring 606 is fixedly connected to the upper surface of the I-shaped slider 602. The diameter of the nail head of the second sliding rod 603 is the same as the diameter of the arc-shaped hole 609. The outer surface of the arc-shaped baffle three 608 is fixedly connected to the outer surfaces of the symmetrically arranged second telescopic baffles 607. The feeding hole 605 is opposite to the feeding trough 8 in position. The first screw rod 601 is used to adjust the position of the arc-shaped baffle two 604. The up-and-down sliding of the second sliding rod 603 is not affected by the arc-shaped hole 609, and the inflow of livestock manure can be assisted through the arc-shaped hole 609. While the arc-shaped baffle three 608 diverts the livestock manure, it protects the I-shaped slider 602 and does not affect the movement of the I-shaped slider 602.

[0048] The adjusting mechanism 9 includes a third rotating rod 901. The third rotating rod 901 is fixedly connected to the inner wall of the mixing tank 1. A first rotating plate 902 is rotatably connected to the outer surface of the third rotating rod 901. A butterfly spring 903 is fixedly connected inside the first rotating plate 902. A sliding plate 904 is fixedly connected to the outer surface of the butterfly spring 903. A second scraping plate 905 is clamped inside the sliding plate 904. A second rotating plate 906 is rotatably connected to the outer surface of the third rotating rod 901. A metal elastic sheet 907 is fixedly connected to the lower surface of the first rotating plate 902. A telescopic plate 908 is fixedly connected to the inner wall of the mixing tank 1. An arc-shaped column 909 is fixedly connected to the outer surface of the telescopic plate 908. The second scraping plate 905 is used to clean the surfaces of the arc-shaped column 909 and the vertical grid 314.

[0049] The sliding plate 904 is slidably connected to the first rotating plate 902. The first rotating plate 902 is rotatably connected to the second rotating plate 906. The outer surface of the metal elastic sheet 907 is fixedly connected to the lower surface of the second rotating plate 906. The outer surface of the second scraping plate 905 is in contact with the outer surface of the arc-shaped column 909. The metal elastic sheet 907 is used to rotationally support the first rotating plate 902 and the second rotating plate 906. While the first rotating plate 902 and the second rotating plate 906 rotate around the third rotating rod 901, the butterfly spring 903 pushes and supports the second scraping plate 905 to clean the surfaces of the arc-shaped column 909 and the vertical grid 314, and supports the horizontal grid 313 to resist the impact pressure and improve the stability and durability of the horizontal grid 313.

[0050] The working principle of this embodiment is as follows: When using this livestock manure and crop straw returning equipment, when putting livestock manure into the feeding trough 8, it flows into the stirring box 1 through the feeding hole 605, and after being diverted by the arc-shaped baffle three 608, it flows onto the upper surface of the arc-shaped baffle one 312 and flows in through the arc-shaped holes 609 on both sides of the arc-shaped baffle one 312 for stirring. The feeding through the feeding hole 605 makes the inflow volume the smallest to ensure that the process will not be interrupted. When the flow rate is too large to enter through the feeding hole 605, it impacts the arc-shaped baffle two 604, causing it to move downward and push the second sliding rod 603 downward. The second spring 606 is compressed, creating a gap between the arc-shaped baffle two 604 and the stirring box 1, and allowing livestock manure to flow in. At this time, the second telescopic baffle 607 is compressed to protect the second spring 606. When the flow rate further increases, the first screw 601 rotates, driving the arc-shaped baffle two 604 to move through the I-shaped slider 602 and the second sliding rod 603, moving it out of the inflow range of the feeding trough 8 to increase the inflow of livestock manure. At this time, when the livestock manure falls through the horizontal grid 313, it pushes the first rotating plate 902 and the second rotating plate 906 to rotate around the third rotating rod 901. While the sliding plate 904 rotates around the third rotating rod 901, it slides inside the first rotating plate 902, and is pushed by the butterfly spring 903 to make the second scraper 905 contact the surface of the arc-shaped column 909. Due to the impact of the livestock manure, the arc-shaped column 909 is pushed, and the telescopic plate 908 is pushed to move outward. Since the sliding distance of the sliding plate 904 is limited by the butterfly spring 903, a gap is created between the surface of the arc-shaped column 909 and the second scraper 905, allowing the livestock manure to continue to fall. The metal elastic sheet 907 pushes the first rotating plate 902 and the second rotating plate 906 to rotate, supporting the first rotating plate 902 and the second rotating plate 906 when the flow rate is small, and enabling the livestock manure to be stirred and fermented inside the stirring box 1. When a certain amount of livestock manure is reached, it pushes the first rotating plate 902 and the second rotating plate 906 to rotate, causing the livestock manure to fall, and is discharged by rotary tillage through the rotating device 5 and returned to the field along with the crop straw, realizing the returning treatment of livestock manure and crop straw to the field.
