Description

Technical Field

[0001] This utility model relates to the field of tillage technology, specifically a composite tillage implement for deep burial of straw for protective purposes. Background Technology

[0002] Currently, straw treatment is a key aspect of conservation tillage in agricultural production. Traditional methods of returning straw to the field mainly include direct crushing and spreading, plowing and returning to the field, or burning. Straw returned directly to the field has a long decomposition period in the soil, which can easily cause an imbalance in the soil carbon-nitrogen ratio, especially in low-temperature areas, affecting the sowing and growth of subsequent crops.

[0003] The existing patent (authorization announcement number: CN222803368U) discloses a straw deep burial protective tillage composite implement. The key technical points of the solution are: the output end of the drive motor drives the drive rotary tiller to rotate, the drive rotary tiller drives the drive pulley to rotate, the drive pulley drives the first-level pulley to rotate through the first-level transmission belt, the first-level pulley drives the drive rotary tiller to rotate, loosening the soil. Then, the soil-expanding plow widens the pit after loosening the soil. Then, the first-level pulley drives the second-level pulley to rotate, the second-level pulley drives the third-level pulley to rotate through the second-level transmission belt, and the third-level pulley drives the equalizing roller to evenly throw the straw fragments to be deeply buried in the feed hopper into the pit. Then, the burial motor drives the rotating rod to rotate, the rotating rod drives one of the gears to rotate, one of the gears drives another gear to rotate, thereby driving the two rotating rods to rotate. The two rotating rods drive the two burial plates to rotate, re-burying the soil piles dug out on both sides of the pit into the pit, thereby achieving the effect of deep burial of straw fragments.

[0004] However, the above-mentioned technical solutions still have certain defects. Pathogens (such as sheath blight and Fusarium head blight) and insect eggs (such as corn borers and underground pests) carried by straw are easy to breed in shallow soil, increasing the incidence of crop diseases. At the same time, straw that is not fully crushed is easy to entangle the machinery when buried deeply, affecting the efficiency of cultivation and even causing mechanical failure. Therefore, a straw deep burial protective cultivation composite machinery is proposed. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-6As shown, a straw deep-burying protective tillage composite implement includes a housing 2, a handle 1 for controlling the movement direction of the device is fixedly installed on the housing 2, drive wheels 3 for facilitating the movement of the device are respectively provided on both sides of the housing 2, a liquid inlet mechanism 4 for inleting liquid medicine is installed on the top of the housing 2, a combing claw 8 for combing straw is provided on the bottom of the housing 2, a first liquid outlet component 5 and a second liquid outlet component 6 are provided at the bottom of the liquid inlet mechanism 4, and a cutting component 7 for cutting straw is provided inside the housing 2; In this embodiment, the cutting component 7 is used to initially cut the straw that is standing or laid out in the field. The liquid inlet mechanism 4 is equipped with a first liquid storage box 41 and a second liquid storage box 42, which can hold different functional liquids to achieve pest and disease control or nutrient supplementation. The combing claw 8 combs the broken straw neatly to avoid accumulation. At the same time, the thrust of the machine pushes the straw into the soil surface. The drive wheel 3 provides the driving power and the direction is controlled by the handle 1 to ensure stable operation of the machine.

[0020] In one embodiment, such as Figure 3 As shown, the liquid inlet mechanism 4 includes a first liquid storage box 41 and a second liquid storage box 42 fixedly installed on the top of the casing 2. The two sets of liquid storage boxes are set separately, and each set of liquid storage boxes has a liquid outlet hole at the bottom. The first liquid storage box 41 is used to hold the composting agent, and the second liquid storage box 42 is used to hold the insecticide. The first liquid storage box 41 is specifically used to hold the straw composting agent, and the second liquid storage box 42 is used to hold the fungicide independently. The two sets of liquid storage boxes are physically isolated to avoid cross-contamination or chemical reaction of the agents. Each liquid storage box has an independent liquid outlet hole at the bottom. The composting agent is directly delivered to the cut surface of the straw through the first liquid outlet hole, and the insecticide is atomized and sprayed onto the surface of the straw and the surrounding soil through the second liquid outlet hole. In one embodiment, such as Figure 4 and Figure 5 As shown, a first liquid outlet assembly 5 is provided at the bottom of the first liquid storage box 41. The first liquid outlet assembly 5 includes a mounting shell 51 fixedly installed inside the housing 2. A limit tube 52 passes through the mounting shell 51. A through hole is opened at the bottom of the mounting shell 51, and the through hole is connected to a liquid outlet pipe 53. A second liquid outlet assembly 6 is provided at the bottom of the second liquid storage box 42. The second liquid outlet assembly 6 includes a liquid inlet 61 connected to a liquid outlet hole at the bottom of the second liquid storage box 42. The liquid inlet 61 is connected to a fixed shell 62. The fixed shell 62 is equipped with a rotating wheel 63 inside, and a liquid outlet is provided on the side of the fixed shell 62 away from the liquid inlet 61. The composting agent flows out from the liquid outlet hole at the bottom of the first liquid storage box 41, passes through the limiting tube 52 inside the mounting shell 51, and enters the liquid outlet pipe 53 through the bottom through hole of the mounting shell 51, and is finally delivered to the straw cross-section. The insecticide enters the fixed shell 62 from the second liquid storage box 42 through the liquid inlet 61. The rotating wheel 63 rotates, driving the liquid to be sprayed out from the liquid outlet. The composting agent improves the decomposition efficiency, and the insecticide reduces the survival rate of insect eggs.

[0021] In one embodiment, such as Figure 6 As shown, the cutting assembly 7 includes a drive motor 71 fixedly mounted on the side of the housing 2. A cutting roller 72 is fixedly mounted on the output end of the drive motor 71. A drive pulley is fixedly mounted on the end of the cutting roller 72 away from the drive motor 71. There are two sets of drive pulleys, namely a first drive pulley and a second drive pulley. The first drive pulley is fixedly connected to the cutting roller 72, and the second drive pulley is fixedly connected to the combing roller 74. The two sets of drive pulleys are connected by a belt 73. The combing claws of the combing roller 74 are parallel to the rotation axis of the cutting roller 72, and the working parts on their surfaces are arranged alternately. The output shaft of the drive motor 71 is connected by a keyway. The cutting roller 72 is directly driven to impact and cut the upright straw. At the same time, while the cutting roller 72 is rotating, the combing roller 74 is driven by the belt 73 and linked with the cutting roller 72. Its combing claws (or combing rods) move alternately with the blades of the cutting roller 72 to further crush and loosen the cut straw, prevent straw entanglement and improve the uniformity of subsequent deep burial. At the same time, the cutting roller 72 and the combing roller 74 work together to realize the segmented crushing of straw (cutting first and then loosening), which solves the problem of easy clogging of traditional implements. In addition, the combing roller 74 and the cutting roller 72 are staggered so that the straw wrapped on the dividing roller can be combed by the combing roller 74.

[0022] As a supplement: the lowest point of the bottom of the cutting roller 72 is 10-15cm lower than that of the combing roller 74, and the width of the blades arranged on the cutting roller 72 is smaller than the width of the combing bars arranged on the surface of the combing roller 74; the cutting roller 72 (main working roller) is lowered by 10-15cm so that its blades contact the straw in the field first, and the cutting roller 72 completes the basic cutting of upright / fallen straw. The combing roller 74 then performs fine crushing. The narrow blade cutting roller 72 improves the penetration of high-density straw, and the wide combing bar combing roller 74 enhances the limiting tearing effect.

[0023] In one embodiment, such as Figure 2 As shown, the combing claw 8 has a pointed claw at one end and a flat claw at the other end, and the drive wheel 3 is equipped with multiple sets of reinforcing rods; the pointed claw end preferentially breaks up the coarse and hard straw remaining in the field, forming a flow channel to reduce forward resistance, while the flat claw end performs secondary compaction on the treated straw layer.

[0024] The above embodiments disclose a straw deep burial conservation tillage composite implement, wherein a first liquid storage box 41 is specially used to hold straw composting agent, and a second liquid storage box 42 is used to hold fungicide. Insecticide enters the fixed shell 62 from the second liquid storage box 42 through the liquid inlet 61. The rotating wheel 63 rotates, driving the liquid to be sprayed out from the liquid outlet. The composting agent improves the decomposition efficiency, and the insecticide reduces the survival rate of insect eggs. The output shaft of the drive motor 71 directly drives the cutting roller 72 through a keyway connection. At the same time, while the cutting roller 72 rotates, the combing roller 74 is driven by the belt 73 and linked with the cutting roller 72. The combing claws and the blades of the cutting roller 72 move alternately to further crush and loosen the cut straw, prevent straw entanglement and improve the uniformity of subsequent deep burial, and prevent the cutting roller 72 from entangled, which would reduce the subsequent cutting effect.

[0025] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
