Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a straw crushing and returning device for eliminating insect eggs in dry fields. Background Technology

[0002] Straw contains abundant nitrogen, phosphorus, potassium, magnesium, calcium, sulfur and other elements, which are essential nutrients for crop growth. By crushing and returning straw to the field, the organic matter in the straw is decomposed and matured by microorganisms, and transformed into nutrients that can be absorbed by plants, effectively replenishing the nutrients in the soil.

[0003] Current straw crushing and returning devices can loosen and agitate the topsoil mechanically, destroying the living environment of pests and reducing the threat of pests and diseases. However, they cannot completely destroy all insect eggs, and pest infestations may still occur during subsequent sowing.

[0004] Therefore, while the existing straw crushing and returning devices can loosen and agitate the topsoil mechanically, thus disrupting the living environment of pests and reducing the threat of pests, they cannot completely destroy all insect eggs, and pest infestations may still occur during subsequent sowing. A straw crushing and returning device for eliminating insect eggs in dry fields can be designed. This device would add insecticide to the crushed straw to further eliminate insect eggs, and then return the insecticide-containing fragments to the field to inhibit the growth of pests in the soil. Utility Model Content

[0023] Please see Figures 1-2 In this embodiment, three sets of mounting frames 201 are fixedly installed inside the air duct 2. The mounting frames 201 are located at the ends of the air duct 2, and a spreading fan 202 is installed inside the mounting frames 201. By setting the mounting frames 201 to install the spreading fan 202, the spreading fan 202 can evenly spread the straw fragments out of the air duct 2 and onto the field, preventing the straw fragments from accumulating and affecting the returning effect to the field. The root cutting component includes a mounting frame 301 and a root cutting wheel 302. The mounting frame 301 is fixedly installed on the frame 1. At one end, the mounting frame 301 has multiple sets of root-cutting wheels 302 inside, which are rotatably connected to the mounting frame 301. The root-cutting wheels 302 are installed by the mounting frame 301 and can cut the roots of the straw. A traction component 401 is fixedly installed on the top of the mounting frame 301, and two sets of support wheels 402 are fixedly installed on both sides of the frame 1. The traction component 401 can be connected to an external drive device to move the whole device, and the support wheels 402 support the frame 1.

[0024] Please see Figures 3-4In this embodiment, the crushing assembly includes a mounting shaft 501 and a crushing roller 502. The mounting shaft 501 passes through the frame 1 and is rotatably connected to the frame 1. The crushing roller 502 is fixedly mounted on the periphery of the mounting shaft 501 and is located inside the frame 1. The crushing roller 502 is mounted by the mounting shaft 501 and can be driven to rotate, thereby crushing the straw. The drive assembly includes a mounting plate 601, a motor 602, pulleys 603, and a transmission belt 604. The mounting plate 601 is fixedly mounted on the top of the frame 1, the motor 602 is fixedly mounted on the top of the mounting plate 601, and three sets of pulleys 603 are provided. One set of pulleys 603 is fixedly mounted on the output end of the motor 602, and the other two sets of pulleys 603 are respectively fixedly mounted on the frame 1. Mounted at one end of two sets of mounting shafts 501, a transmission belt 604 is set around three sets of pulleys 603; a motor 602 is mounted on a mounting plate 601, and the motor 602 drives one set of pulleys 603 to rotate, thereby driving the other two sets of pulleys 603 mounted at one end of the mounting shaft 501 to rotate via the transmission belt 604, thereby driving the mounting shaft 501 and the crushing roller 502 mounted around it to rotate; two sets of connecting frames 701 are set on both sides of the frame 1, and the connecting frames 701 are rotatably connected to the frame 1; a compaction roller 702 is set between the two sets of connecting frames 701, and the compaction roller 702 is rotatably connected to the connecting frames 701; the compaction roller 702 is mounted on the connecting frames 701, and the compaction roller 702 can compact and level the land where the crushing roller 502 pulls out the straw.

[0025] When working, the traction component 401 can be used to connect to an external drive device to move the entire device in the field.

[0026] During operation, the root cutting wheel 302 is used to cut the root of the straw first. The motor 602 drives a set of pulleys 603 to rotate. The transmission belt 604 drives three sets of pulleys 603 to rotate synchronously, thereby driving the mounting shaft 501 to rotate. The crushing roller 502 rolls up and crushes the straw with the cut root.

[0027] The medicine can be delivered from the storage tank 102 to the distribution box 105 via the connecting pipe 104. The distribution box 105 can distribute the medicine to each dripper 106 and drip it out via the dripper 106. The connecting pipe 104 can be controlled by the valve 103.

[0028] After crushing, the spraying fan 202 provides negative pressure to the air duct 2. The crushed straw is sucked into the air duct 2. When passing through the air duct 2, the pesticide dripped from the dripper 106 mixes with the straw fragments and is evenly sprayed back into the field by the spraying fan 202.

[0029] Finally, the compaction roller 702 is used to level and compact the soil that was broken up when the straw was pulled out.

[0030] Through the above steps, the crushed straw fragments can be sucked up through the air duct 2. As the straw passes through the air duct 2, the pesticide in the storage box 102 can be dripped into the straw fragments using the dripper 106 to further disinfect insect eggs. The straw fragments can also be returned to the field to control field pests. This solves the problem that current straw crushing and returning devices can loosen and stir the topsoil mechanically, destroying the living environment of pests and reducing the threat of diseases and pests, but cannot completely destroy all insect eggs, and there may still be pest problems during subsequent sowing.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
