Description

Technical Field

[0001] The utility model relates to the technical field of wheat harvesters capable of suppressing dust, in particular to a wheat harvester capable of suppressing dust. Background Art

[0002] During the wheat harvesting process, a large amount of dust and impurities will be generated due to the high-speed operation and cutting of the harvester. These dust and impurities will not only pollute the environment, but also affect the health of the operators.

[0003] The utility model with the existing authorization announcement number CN211936173U discloses a dust suppression device for a wheat combine harvester, including a harvester body and a collecting box; a mounting plate is horizontally fixedly installed on the upper end of the front side of the harvester body, an air pump is arranged on the left side of the upper surface of the mounting plate, and an air intake pipe of the air pump passes through the mounting plate and is connected to a trumpet-shaped guide groove.

[0004] By adopting the above technical scheme, the utility model controls the operation of the vacuum pump, and can draw the dust generated by the harvester body during the harvesting operation into the filter box through the air intake pipe, and filter it through the filter screen. Since the filter screen has been used for a long time, the mesh is easy to be blocked, and the driving motor is controlled to work, and the brush can be driven to rotate through the rotating rod, and the dust on the outside of the filter screen can be automatically cleaned. The cleaned dust is discharged into the collection box through the collection port for collection. Since the dust is filtered by the filter screen, it still contains a lot of tiny dust, which is introduced into the water tank through the air duct, and is further adsorbed and purified by the water in the water tank. However, the above technical scheme cannot collect all the dust generated when harvesting wheat because there is no dust cover, so the dust suction effect is not very good. In addition, the above technical scheme does not spray the discharged straw evenly, and it is easy to splash and scatter everywhere, which is not conducive to other vehicles entering the site. For this reason, the above technical scheme needs to be improved.

[0005] Therefore, those skilled in the art provide a wheat harvester capable of suppressing dust to solve the problems raised in the above-mentioned background technology. Utility Model Content

By providing the saw teeth 8, the saw teeth 8 can quickly cut off the wheat to prevent blockage.

[0027] The telescopic end of the telescopic rod 205 is movably hinged to the outer surface of the dust cover 204, and the spraying mechanism 3 includes a water inlet pipe 301. The outer surface of the water inlet pipe 301 is fixedly connected to the right side surface of the storage box 1, and the top of the water inlet pipe 301 is fixedly connected to the water tank 302. The upper surface of the storage box 1 is fixedly connected to two limit seats 9, and the inner walls of the two limit seats 9 are fixedly connected to the outer surface of the water tank 302. The limit seats 9 are provided to fix the water tank 302, so as to ensure the stability of the water tank 302 and prevent it from shaking during the movement of the harvester.

[0028] The outer surface of the water tank 302 is fixedly connected to a water outlet pipe 303, and the outer surface of the water outlet pipe 303 is fixedly connected to a boost valve 304. The bottom surface of the boost valve 304 is fixedly connected to the upper surface of the storage box 1. The end of the water inlet pipe 301 away from the water tank 302 is fixedly connected to a switch valve 10. The switch valve 10 is located on the right side of the storage box 1. By providing the switch valve 10, the flow rate and start and stop of adding water to the water tank 302 can be controlled.

[0029] A spray box 305 is fixedly connected to the back of the storage box 1, and one end of the water outlet pipe 303 away from the boost valve 304 passes through the spray box 305 and extends to the inside of the spray box 305. Nine nozzles 307 are fixedly connected to the outer surface of the water outlet pipe 303, and a plurality of plastic curtains 306 are fixedly connected to the bottom surface of the spray box 305. Six hanging buckles 11 are fixedly connected to the outer surface of the water outlet pipe 303, and the top surface of each hanging buckle 11 is fixedly connected to the inner top wall of the spray box 305. By providing the hanging buckle 11, the water outlet pipe 303 is hung inside the spray box 305.

[0030] The working principle of the utility model is as follows: when in use, firstly, the boost valve 304 is electrically connected through a wire, and then the switch valve 10 is connected through an external water pipe, and the switch valve 10 is opened to allow water to flow along the water inlet pipe 301 into the water storage tank 302, and when the water storage tank 302 is filled with water, the switch valve 10 is closed, and then the harvester is moved to the side of the wheat field by using the front wheels 6 and the rear wheels 7, and then the harvesting shovel 202 is lowered to a suitable position to start harvesting wheat;

[0031] At this time, the wheat is harvested and cut by the saw teeth 8 and the rotating circle 203 is used to roll the wheat into the interior of the suction pipe 201. The dust is sucked into the interior of the storage box 1 by the suction force generated by the suction system arranged inside the storage box 1. If the dust is large at this time, the dust cover 204 can be appropriately lowered by the telescopic rod 205 to cover the dust in a larger range to ensure that most of the dust can be absorbed. Then, the filtering system inside the storage box 1 is used to screen and separate the wheat and the straw. The wheat is stored and retained, while the straw is transported to the spray box 305 for discharge.

[0032] At this time, the screened straw is discharged from the storage box 1 to the spray box 305. The water in the water tank 302, which is in a higher position, will naturally flow to the water outlet pipe 303. The boost valve 304 is used for secondary pressurization to make the water inside the water outlet pipe 303 full of pressure, so that fine water mist can be discharged from the nozzle 307. At this time, the straw falls to the ground along with the water mist. The design of the plastic curtain 306 can prevent the straw from splashing everywhere when it is discharged, thereby ensuring that the discharged straw is neat and uniform and will not affect other working vehicles. The wheat harvester that can suppress dust can reduce dust pollution by covering the dust during harvesting and spraying water mist during discharge to maximize the purpose of suppressing dust.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
