Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology; more specifically, it relates to a high-efficiency straw decomposition device. Background Technology
[0002] Straw is an important renewable biological resource, rich in nutrients such as nitrogen, phosphorus, and potassium, as well as organic matter. In agriculture, returning straw to the field is one of its main utilization methods, which can be done directly through crushing, plowing, or mulching. This effectively increases soil organic matter content, improves soil structure, enhances water and fertilizer retention capacity, and reduces the use of chemical fertilizers. In addition, straw can also be used as a substrate for cultivating edible fungi, or indirectly returned to the field to improve soil fertility through composting or as manure after digestion by livestock. The comprehensive utilization of straw is of great significance for promoting sustainable agricultural development.
[0003] The high-efficiency straw decomposition device is a mechanical equipment used for agricultural straw return to the field. It integrates functions such as crushing and spraying decomposing agents to accelerate straw decomposition and improve soil fertility.
[0004] Currently, in agricultural planting, existing equipment typically uses crushing rollers to shred straw. When the blades on the outer side of these rollers wear down, the shredding effect decreases, resulting in uneven straw size. This can affect subsequent mixing and the spraying of decomposing agents, reducing the equipment's practicality. Furthermore, most existing equipment uses decomposing agents to spray the shredded straw, but these agents often contain impurities. When there are many impurities, the spray nozzles can become clogged, leading to uneven spraying and further reducing the equipment's usability. Therefore, there is an urgent need for a high-efficiency straw decomposition device to solve these problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a straw high-efficiency decomposition device to solve the problems existing in the background art.

[0007] Preferably, the motor is mounted on the outer surface of the upper end of one end of the mixing tank, and the output end of the motor is fixedly connected to a first gear, and the outer surface of the first gear is meshed with a second gear. The inner surfaces of the inner walls on both sides of the upper end of the mixing tank are connected to mounting shafts by bearings. The outer surfaces of the two sets of mounting shafts and the first and second gears are fixedly connected to mounting plates at their respective ends. The inner surfaces of the four sets of mounting plates at their respective ends are provided with mating grooves, and the inner wall surface of one side of the mating groove is provided with a movable groove. A first insert rod is inserted into the movable groove. The movable grooves are provided with first springs. The four sets of mating grooves are provided with mounting blocks. Two sets of mounting blocks are fixedly connected to the outer surfaces of their respective ends, and there are two sets of crushing rollers. The inner surfaces of one side of the four sets of mounting blocks are provided with insertion holes. This design allows the first insert rod to move inside the movable groove.
[0008] Preferably, one end of the first insertion rod is fixedly connected to a toggle plate, and the external dimensions of the toggle plate are adapted to the internal dimensions of the movable groove. The two ends of the first spring abut against the inner wall surface of the movable groove and the outer surface of one side of the toggle plate, respectively. This design prevents the first insertion rod from detaching from the movable groove when it moves inside the movable groove.
[0009] Preferably, the external dimensions of the other end of the first insertion rod are adapted to the internal dimensions of the insertion hole, and this design allows the other end of the first insertion rod to be inserted into the insertion hole.
[0010] Preferably, the outer surface of one side of the water tank is fixedly connected to the outer surface of one side of the mixing tank, and a water pump is installed inside the water tank. The output end of the water pump is fixedly connected to a transmission pipe. A filter box is fixedly connected to the upper end of the transmission pipe. A fixing groove is opened inside the outer surface of one side of the filter box, and an insertion port is opened inside the fixing groove. A movable sleeve is fixedly connected to the outer surface of the upper side of the filter box, and a second insertion rod is inserted inside the movable sleeve. A second spring is sleeved on the outer surface of the second insertion rod. A filter plate is inserted inside the insertion port. A fixing block is fixedly connected to the outer surface of one end of the filter plate. A positioning hole is opened inside the upper outer surface of the fixing block, and the fixing block is made of rubber. A conveying pipe is fixedly connected to the outer surface of the upper end of the filter box. One end of the conveying pipe is installed inside the inner wall surface at the middle position of the mixing tank, and a nozzle is fixedly connected to the inner surface of the diversion pipe.

The filter plate is made of stainless steel, and the inner dimensions of the fixing groove are adapted to the outer dimensions of the fixing block. This design allows the second insertion rod to automatically reset under the elasticity of the second spring after moving inside the movable sleeve.
[0012] The technical effects and advantages of this utility model are as follows: By moving the actuating plate outward, the first insertion rod moves outward from the inside of the movable groove, thereby disengaging the other end of the first insertion rod from the insertion hole. At this time, the crushing roller can be moved upward, and the mounting block can be disengaged from the docking groove. Then, the positions of the mounting blocks at both ends of the unused crushing roller can be aligned with the positions of the docking groove. The mounting block can then be inserted into the docking groove. Afterward, the actuating plate can be released, allowing the first insertion rod to reset itself under the elasticity of the first spring. This allows the other end of the first insertion rod to be inserted into the corresponding insertion hole, positioning the mounting block inside the docking groove. This completes the replacement of the crushing roller, thus avoiding uneven crushing of straw and preventing any impact on the subsequent mixing effect of the stirring rod. This improves the practicality of the equipment to a certain extent. The filter plate itself filters the decomposition liquid drawn out from inside the water tank, thus preventing nozzle clogging and uneven spraying of the decomposition agent. This improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The agricultural planting involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1, as Figures 1-5 As shown, this embodiment proposes a high-efficiency straw decomposition device, including: a mixing box 1, a pouring port 2 fixedly connected to the upper end of the mixing box 1, a replacement structure 3 provided inside the upper end of the mixing box 1, a mixing rod 4 provided inside the lower end of the mixing box 1, a filter structure 5 provided on the outer surface of one side of the mixing box 1, and a discharge port 6 fixedly connected to the outer surface of the lower end of the other side of the mixing box 1. The replacement structure 3 includes a motor 31, a first gear 32, a second gear 33, a mounting shaft 34, a mounting plate 35, a docking groove 36, a movable groove 37, a first insertion rod 38, a first spring 39, a mounting block 310, a crushing roller 311, and an insertion hole 312. The motor 31 is mounted on the outer surface of the upper end of one end of the mixing tank 1, and the output end of the motor 31 is fixedly connected to the first gear 32. The outer surface of the first gear 32 is meshed with the second gear 33. The inner walls on both sides of the upper end of the mixing tank 1 are connected to the mounting shaft 34 by bearings. Mounting plates 35 are fixedly connected to the outer surfaces of the four mounting shafts 34, the first gear 32, and the second gear 33 at their respective ends. Each of the four mounting plates 35 has a mating groove 36 on the inner surface of its respective side. A movable groove 37 is formed on the inner wall surface of one side of the mating groove 36, and a first inserting rod 38 is inserted into the movable groove 37. A first spring 39 is provided inside each of the movable grooves 37. Mounting blocks 310 are inserted into the inner surfaces of the four mating grooves 36, and two sets of mounting blocks 310 at their respective ends have their outer surfaces... A crushing roller 311 is fixedly connected, and there are two sets of crushing rollers 311. Insertion holes 312 are opened inside the outer surface of one side of each of the four sets of mounting blocks 310. One end of the first insertion rod 38 is fixedly connected to a deflector plate, and the external dimensions of the deflector plate are adapted to the internal dimensions of the movable groove 37. The two ends of the first spring 39 abut against the inner wall surface of the movable groove 37 and the outer surface of one side of the deflector plate, respectively. The external dimensions of the other end of the first insertion rod 38 are adapted to the internal dimensions of the insertion hole 312. This design allows the first insertion rod 38 to move within the movable groove 37. This design ensures greater stability and prevents the first insertion rod 38 from dislodging from the movable groove 37 during its movement. Furthermore, the design allows the first insertion rod 38 to automatically reset under the elasticity of the first spring 39 after moving within the movable groove 37, thus enabling the other end of the first insertion rod 38 to be inserted into the insertion hole 312. This allows for positioning of the mounting block 310 inside the mating groove 36. Simultaneously, this design ensures greater stability when the other end of the first insertion rod 38 is inserted into the insertion hole 312.
[0021] Example 2, as Figure 4 and Figure 5As shown, based on the same concept as the above embodiments, this embodiment also proposes: the filter structure 5 includes a water tank 51, a water pump 52, a transmission pipe 53, a filter box 54, an insertion port 55, a movable sleeve 56, a second insertion rod 57, a second spring 58, a filter plate 59, a positioning hole 510, a conveying pipe 511, and a nozzle 512. The outer surface of one side of the water tank 51 is fixedly connected to the outer surface of one side of the mixing tank 1, and the water pump 52 is installed inside the water tank 51. The output end of the water pump 52 is fixedly connected to the transmission pipe 53. The upper end of the transmission pipe 53 is fixedly connected to the filter box 54. A fixing groove is opened inside the outer surface of one side of the filter box 54, and an insertion port 55 is opened inside the fixing groove. The movable sleeve 56 is fixedly connected to the outer surface of the upper side of the filter box 54, and a second insertion rod 57 is inserted inside the movable sleeve 56. The outer surface of the filter box 54 is fitted with a second spring 58. The filter plate 59 is inserted into the insertion port 55. A fixing block is fixedly connected to the outer surface of one end of the filter plate 59. A positioning hole 510 is opened in the inner surface of the upper outer surface of the fixing block. The fixing block is made of rubber. A conveying pipe 511 is fixedly connected to the outer surface of the upper end of the filter box 54. One end of the conveying pipe 511 is installed in the inner wall surface at the middle position of the mixing tank 1. A nozzle 512 is fixedly connected to the inner surface of the distribution pipe. Multiple nozzles 512 are provided. A limit ring is fixedly connected to the outer surface of the second insertion rod 57. The two ends of the second spring 58 abut against the inner wall surface of the movable sleeve 56 and the surface of one side of the limit ring, respectively. The outer dimensions of the lower end of the second insertion rod 57 are adapted to the inner dimensions of the positioning hole 510. The filter plate 59 is made of stainless steel. The inner dimensions of the fixing groove are adapted to the outer dimensions of the fixing block. In this embodiment, the design allows the second insertion rod 57 to automatically reset under the elasticity of the second spring 58 after moving inside the movable sleeve 56. This allows the lower end of the second insertion rod 57 to be inserted into the positioning hole 510, thereby positioning the filter plate 59 inside the insertion port 55. This design also allows the fixing block to be inserted into the fixing groove, making it more stable. The good elasticity and sealing properties of the fixing block material itself can prevent leakage at the connection between the insertion port 55 and the filter plate 59. At the same time, the good corrosion resistance and easy cleaning properties of the filter plate 59 material itself can improve the service life of the filter plate 59, thereby avoiding the need for frequent replacement of the filter plate 59. The motor 31 and the water pump 52 are products that can be purchased directly on the market. Their principles, connection methods and control methods are existing technologies that are well known to those skilled in the art, so they will not be described in detail here. The second insertion rod 57 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.
[0022] Working principle: When the device is in use, starting the motor 31 causes the output end of the motor 31 to drive the first gear 32 to rotate, which in turn drives the second gear 33 to rotate, thereby driving the two sets of crushing rollers 311 to rotate. This crushes the straw placed inside the pouring port 2 through the two sets of crushing rollers 311, and the crushed straw falls into the lower part of the mixing tank 1. At this time, the stirring rod 4 can be started to stir the crushed straw, and the water pump 52 is started simultaneously to draw the decomposition water from the water tank 51 and let the decomposition water enter the filter box 54 through the transmission pipe 53. The mixing chamber 1 is equipped with a mixing unit, and the calcination water is filtered through a filter plate 59. The filtered calcination water then enters the distribution pipe through the conveying pipe 511 and is sprayed onto the crushed straw through multiple sets of nozzles 512. After the straw is mixed, the discharge port 6 can be opened to discharge the mixed straw from the lower end of the mixing chamber 1. When the crushing roller 311 needs to be replaced, the actuating plate can be moved outward, causing the first insertion rod 38 to move outward from the movable groove 37, thereby disengaging the other end of the first insertion rod 38 from the insertion hole 312. At this time, the crushing roller 311 can be moved upward, and the mounting block 310 can be disengaged from the docking groove 36. Inside, the positions of the mounting blocks 310 at both ends of the unused crushing roller 311 can be aligned with the positions of the docking groove 36. The mounting blocks 310 can then be inserted into the docking groove 36. The actuating plate can then be released, allowing the first insertion rod 38 to automatically reset under the elasticity of the first spring 39. This allows the other end of the first insertion rod 38 to be inserted into the corresponding insertion hole 312, thus positioning the mounting blocks 310 inside the docking groove 36. This completes the replacement of the crushing roller 311. When the outer surface of the filter plate 59 is blocked by a large amount of impurities, the second insertion rod 57 can be moved upwards, causing the lower end of the second insertion rod 57 to... After disengaging from the positioning hole 510, the filter plate 59 can be pulled out from the insertion port 55. The filter plate 59 can then be cleaned. After cleaning, the filter plate 59 can be reinserted into the insertion port 55, and the fixing block can be inserted into the fixing groove. At this time, the second insertion rod 57 can be released, allowing it to reset itself under the elasticity of the second spring 58. This allows the lower end of the second insertion rod 57 to be inserted into the positioning hole 510, positioning the filter plate 59 inside the insertion port 55. This completes the replacement of the filter plate 59. The above is the entire working principle of this utility model.
[0023] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
