Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high-pressure fan component of a straw recycling machine. Background Art

[0002] With the acceleration of agricultural modernization, the recycling and utilization of crop straw has become an important part of agricultural sustainable development. Although there are many straw recycling machines on the market, there are still many deficiencies in the straw recycling process, especially in the treatment and utilization of straw after crushing.

[0003] At present, after crushing the straw, the straw recycling machine usually uses a high-pressure fan to directly blow out the straw to the storage or processing area, but this method is prone to dust pollution and is not conducive to environmental protection requirements. Especially when processing green straw, if the straw is not moisturized in time, it will cause the straw to lose water and deteriorate, affecting its subsequent utilization value. In addition, during long-term use, straw recycling equipment is prone to accumulate dust and debris, affecting the normal operation and recycling efficiency of the equipment;

[0004] In response to the above problems, this utility model patent proposes a high-pressure fan assembly for a straw recycling machine, which aims to achieve effective processing and utilization of straw after crushing by improving the structure and function of the fan assembly, while improving the environmental protection and operating efficiency of the equipment.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a high-pressure fan assembly of a straw recycling machine, including a fan housing 1, a blade shaft 5 and a blade 12, the blade shaft 5 is rotatably installed in the fan housing 1 through a bearing, a plurality of blades 12 are fixedly connected to the outer wall of the blade shaft 5 at equal intervals, a cavity 6 is provided in the blade shaft 5, a water inlet nozzle 8 is rotatably installed at one end of the blade shaft 5 through a bearing, a water cavity is provided in the blade 12, a water outlet hole is provided at one end of the blade 12 away from the blade shaft 5, the water cavity 6 and the water outlet hole are connected to each other, a card slot 7 is provided at the air outlet end of the fan housing 1, a windshield plate 2 is slidably connected in the card slot 7, and a top at the air outlet end of the fan housing 1 is provided. An air outlet 3 is installed through the plate, and the diameter of the air outlet 3 increases from top to bottom. A pipe joint 4 is installed on the top of the air outlet 3, and a valve is installed on the pipe joint 4. The windshield member 2 is composed of a first windshield 21 and a second windshield 22. One end of the first windshield 21 and one end of the second windshield 22 are hinged together. The length of the second windshield 22 is the same as the thickness of the fan housing 1 plate. A positioning bolt is installed through a thread at one end of the first windshield 21 away from the second windshield 22. One end of the positioning bolt is threadedly installed on the outer wall of the fan housing 1 for fixing the windshield member 2. When the straw crusher is working normally, the first windshield 2 1 and the second windshield 22 are folded 90 degrees, and the first windshield 21 is fixed to one side of the fan housing 1 by a positioning bolt. At this time, the wind generated by the device can be discharged normally from the air outlet end of the fan housing 1 to blow out the crushed straw. At the same time, the water inlet 8 can be connected to the external water source through a water pipe and a submersible pump. Under the action of the submersible pump, the external water source can enter the cavity 6 of the fan shaft 5 through the water inlet 8, and then flow into the water cavity of the fan blade 12, and finally flow out from the water outlet. When the fan blade 12 rotates at a high speed, it can not only disperse the water in atomization, but also make the atomized water blown out from the air outlet end in combination with the wind generated by the fan blade 12, so that the crushed straw can be effectively controlled. The purpose of dust reduction can be achieved by the straw after recycling. If the silage straw is recycled, its moisture content can be further guaranteed. When the first wind shield 21 and the second wind shield 22 are in a complete plate state, the first wind shield 21 is removed into the card slot 7 of the fan housing 1. At this time, the wind shield 2 blocks the air outlet end of the fan housing 1, and the air duct is connected to the pipe joint 4. The valve on the pipe joint 4 is opened. At this time, the air flow generated by the rotation of the fan blades 12 can be discharged from the pipe joint 4. At this time, the staff can hold the air duct to purge the straw recycling equipment to achieve the purpose of cleaning the straw recycling equipment. The device has a clever structure and diverse functions, which is conducive to promotion.

[0022] Furthermore, one end of the fan shaft 5 away from the water inlet nozzle 8 is a closed structure, and a pulley 11 is fixedly installed on the one end of the fan shaft 5 away from the water inlet nozzle 8.

[0023] Furthermore, a water inlet nozzle fixing part 9 is fixedly sleeved on the outer wall of the water inlet nozzle 8, and a fixing bolt 10 is threadedly installed on the water inlet nozzle fixing part 9. One end of the fixing bolt 10 is threadedly connected to the outer wall of the fan housing 1, and is used to fix the water inlet nozzle 8 after the water inlet nozzle 8 is connected to an external water source.

[0024] Furthermore, an air inlet slot is provided on one side of the fan housing 1 for external airflow to enter the fan housing 1 , and a sealing strip is provided on the edge of the slot 7 to ensure the sealing of the windshield member 2 after it is inserted into the slot 7 .
