Technical Field

[0001] The utility model relates to the technical field of dust-proof fans, in particular to a dust-proof fan. Background Art

[0002] Agricultural machinery condenser exhaust fans are specialized cooling devices used in agricultural machinery. Their primary function is to quickly dissipate heat generated by the condenser through the fan's rotation, ensuring the machinery can operate normally even in high-temperature environments. These fans are typically highly efficient and durable, adapting to various harsh farmland environments. By dissipating heat promptly, they not only improve the efficiency of the machinery but also extend its service life.

[0003] According to the Chinese patent announcement number: CN218764084U, a sugarcane harvester has a built-in air-conditioning condenser, including a condenser shell, two exhaust fans, two prefabricated mounting plates and a heat dissipation copper tube; the condenser shell is rectangular in shape; the two prefabricated mounting plates are detachably connected to the wide sides of the condenser shell for installing the condenser; the two exhaust fans are arranged on the surface of the condenser shell; and a heat dissipation copper tube is arranged on one side of the condenser shell for heat dissipation.

[0004] In the above solution, an exhaust fan is used to prevent the condenser from being blocked by debris, and the cavity position of the fan blade is installed in the opposite direction of the condenser, resulting in the following disadvantages: dust or straw may enter the cavity and solidify to form hard lumps, which may cause friction between the hard lumps and the motor to increase resistance, easily causing the current to increase and burn the fan, reducing safety during use. Utility Model Content

[0005] The purpose of the utility model is to provide a dust-proof fan to solve the problem that dust or straw may enter the cavity and solidify to form hard lumps, which may cause friction between the hard lumps and the motor to increase resistance, easily causing the current to increase and burn the fan, thereby reducing safety during use.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a dust-proof fan, comprising a condensing fan housing, which is detachably arranged on the top surface of the condenser, a fan blade body is rotatably arranged inside the condensing fan housing, and the cavity of the fan blade body is facing the condenser, a mounting hole is provided on the top surface of the condensing fan housing, a motor is detachably provided inside the mounting hole, one end of the motor output shaft passes through the fan blade body and is threadedly connected with a nut, and a plurality of air vents are provided on the top surface of the condensing fan housing.

[0007] Preferably, a washer is slidably inserted on the output shaft of the motor, and the washer is located between the fan blade body and the nut.

[0008] Preferably, a plurality of threaded holes are provided on the top surface of the condensing fan casing, a fixing ring is fixed on the surface of the motor, a plurality of fixing tubes are fixed on the fixing ring, a fixing bolt is rotatably inserted inside the fixing tube, and one end of the fixing bolt passes through the fixing tube and is threadedly connected to the threaded hole.

[0009] Preferably, a plurality of mounting rings are fixed to the surface of the condensing fan housing, mounting bolts are rotatably inserted into the mounting rings, and the mounting bolts pass through the mounting rings and are threadedly connected to the top surface of the condenser.

[0010] Preferably, a plurality of positioning plates are fixed on the surface of the condensing fan housing, and a positioning opening is provided on one side of the positioning plate.

[0011] Preferably, a plurality of ventilation holes are provided on one side of the condenser.

[0012] Compared with the prior art, a dust-proof fan adopting the above technical solution has the following beneficial effects:

[0013] 1. When the agricultural machinery is in use, the condenser inside it is also in working state. At this time, the motor is in working state, and the output shaft of the motor will drive the fan blade body to rotate synchronously. During the rotation, the air containing a large amount of heat inside the condenser is extracted and transported to the external environment. In this process, since the cavity part of the fan blade body is installed downward facing the condenser, dust, straw and other debris in the external environment cannot accumulate in the space of the fan blade body, which can prevent dust, straw and other debris from mixing with water and condensing into hard lumps inside the fan blade body, preventing the situation where the hard lumps hinder the operation of the motor and cause it to burn out, thereby increasing the safety of the motor;

[0014] 2. When assembling the condenser, the staff will first install the motor inside the mounting hole and keep the fixing tube and the central axis of the threaded hole in the same straight line. Then the staff will use the fixing bolt to pass through the fixing tube and screw it into the inside of the threaded hole to fix the motor inside the mounting hole. At the same time, the staff will also use the mounting bolt to pass through the mounting ring and screw it into the top surface of the condenser to fix the condenser fan casing on the top surface of the condenser. When the facilities inside the condenser fan casing are damaged, the staff can disassemble and repair it by unscrewing the fixing bolts and mounting bolts, which increases the convenience during maintenance.

[0015] 3. When installing the condenser fan casing, the staff can first use the positioning port to clamp the raised points on the top surface of the condenser inside, thereby increasing the convenience of installing the condenser fan casing. When the fan blade body is working, it will draw out the air inside the condenser, and then the condenser will replenish air through the vents, thereby increasing the heat dissipation efficiency of the condenser.

[0023] During use, when the agricultural machinery is in use, the condenser 1 inside it is also in a working state. At this time, the motor 5 is in a working state, and the output shaft of the motor 5 will drive the fan blade body 3 to rotate synchronously. During the rotation, the air containing a large amount of heat inside the condenser 1 is extracted and transported to the external environment. In this process, since the cavity part of the fan blade body 3 is installed facing downward toward the condenser 1, dust, straw and other debris in the external environment cannot accumulate in the space of the fan blade body 3, which can prevent dust, straw and other debris from mixing with water and condensing into hard lumps inside the fan blade body 3, thereby preventing the motor 5 from burning out due to the hard lumps hindering its operation, thereby increasing the safety of the motor 5.

[0025] During use, when the staff assembles the condenser 1, the staff will first install the motor 5 inside the mounting hole 4, and keep the fixing tube 11 and the central axis of the threaded hole 9 in the same straight line. Then the staff uses the fixing bolt 12 to pass through the fixing tube 11 and screw it into the inside of the threaded hole 9 to fix the motor 5 inside the mounting hole 4. At the same time, the staff will also use the mounting bolt 14 to pass through the mounting ring 13 and screw it into the top surface of the condenser 1 to fix the condenser fan housing 2 on the top surface of the condenser 1. When the facilities inside the condenser fan housing 2 are damaged, the staff can disassemble and repair it by unscrewing the fixing bolt 12 and the mounting bolt 14, which increases the convenience during maintenance.
