Technical Field
[0001] This invention relates to the field of harvester radiators, specifically a dust removal device for harvester radiators. Background Technology
[0002] Currently, most harvester radiator dust removal systems use rotating suction dust covers, which lack a dust cleaning mechanism, allowing dust to easily clog the covers. Furthermore, opening the rotating cover to clean dust and grime from the radiator grille requires removing the drive belt, which is very inconvenient. Summary of the Invention
[0003] The purpose of this invention is to provide a dust removal device for a harvester radiator, which can conveniently clean the dust and dirt on the radiator grid without removing the dust cover and the drive belt on the radiator, and can prevent dust from splashing and affecting other parts of the harvester.
[0004] The objective of this invention can be achieved through the following technical solutions: A dust removal device for a harvester radiator includes a radiator housing, a cooling fan, and a radiator grid. The radiator grid is installed inside the housing, and the cooling fan is connected to the front of the housing and positioned directly opposite the radiator grid. The dust removal device includes a rotating screen, a screen mounting plate, a dust removal mechanism, a rotating screen belt, a rotating screen drive wheel, and a wheel drive mechanism. The housing has an opening on the side away from the cooling fan. The upper and lower ends of the opening are rotatably connected to the screen mounting plate. The rotating screen is rotatably connected to a mounting hole on the side of the screen mounting plate away from the opening. One end of the rotating screen belt is fitted onto the outer surface of the rotating screen, and the other end of the rotating screen belt is fitted onto the rotating shaft drive wheel. The rotating screen drive wheel is connected to the wheel drive mechanism, which is connected to one side of the housing. The dust removal mechanism is connected to the side of the rotating screen away from the screen mounting plate, and the rotating screen removes dust through the dust removal mechanism.
[0005] Furthermore, the dust removal mechanism includes a horizontal suction plate and a brush. The horizontal suction plate is connected to the negative pressure side of the housing through a suction pipe, and the brush is connected to the side of the horizontal suction plate near the rotating screen and abuts against the rotating screen.
[0006] Furthermore, the suction plate has suction holes at the end near the brush, with the suction holes facing the end of the brush near the rotating mesh cover.
[0007] Furthermore, the air intake duct is located at the end of the housing away from the rotating mesh cover and on the air intake side of the cooling fan, while the cooling fan is located on the side of the heat dissipation grid away from the rotating mesh cover.
[0008] Furthermore, the wheel drive mechanism includes a first fixed frame, a second fixed frame, a main drive shaft, a pulley, and a drive belt. The first fixed frame is connected to the side of the housing away from the rotating mesh cover, the second fixed frame is connected to one side of the housing, the main drive shaft is rotatably connected between the first fixed frame and the second fixed frame, the pulley and the rotating mesh cover drive wheel are respectively connected to both ends of the main drive shaft, and the pulley is connected to the drive wheel on the engine output shaft through the drive belt.
[0009] Furthermore, the mesh cover mounting plate is connected to a belt tensioning mechanism, which is used to tension the rotating cover belt.
[0010] Furthermore, the belt tensioning mechanism includes a tension spring, a first tension wheel, a second tension wheel, a rotating plate, and a spring mounting plate. The first tension wheel is rotatably connected to the mesh cover mounting plate and located on one side of the rotating mesh cover. The second tension wheel is rotatably connected to the middle of the rotating plate. One end of the rotating plate is rotatably connected to the mesh cover mounting plate and located below the first tension wheel. The other end of the rotating plate is connected to one end of the tension spring, and the other end of the tension spring is connected to the spring mounting plate. The spring mounting plate is connected to the mesh cover mounting plate and located above the other end of the rotating plate. The upper ends of both the first and second tension wheels are connected to the rotating mesh cover belt.
[0011] Furthermore, the upper and lower ends of the mesh cover mounting plate near the wheel drive mechanism are provided with rotating structures, and the mesh cover mounting plate is rotatably connected to the housing through the rotating structures.
[0012] Furthermore, the rotating structure is a bolt shaft, which is rotatably connected to a bolt shaft hole provided on the housing.
[0013] Furthermore, the middle part of the dust removal mechanism is connected to the middle part of the mesh cover mounting plate, and the upper and lower parts of the mesh cover mounting plate near the dust removal mechanism are detachably connected to the housing by snap fasteners.
[0014] The beneficial effects of this invention are: This invention incorporates a dust-blocking mechanism, including a housing, a rotating mesh cover, and a mesh cover mounting plate. The rotation of the mesh cover prevents dust accumulation. In situations where harvesting generates significant dust, this not only protects components within the radiator body, such as the radiator grid, but also reduces the amount of dust entering these components. When dust enters the radiator grid and rotating mesh cover inside the housing, the rotation of the mesh cover prevents dust accumulation. The rotating mesh cover, through a dust removal mechanism, removes any remaining dust. Opening the mesh cover mounting plate on the back of the housing facilitates cleaning the dust from the radiator grid inside the rotating mesh cover without removing the fan and belt in front of the radiator grid, thus solving the problem of difficult dust and dirt removal from the radiator grid for harvester users.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] like Figure 1As shown, a dust removal device for a harvester radiator is disclosed. The radiator includes a housing 1, a radiator grille, and a cooling fan. The radiator grille is installed inside the housing 1, and the cooling fan is connected to the front of the housing 1 and positioned directly opposite the radiator grille. The dust removal device includes a rotating screen 2, a screen mounting plate 3, a dust removal mechanism 6, a rotating screen belt 4, a rotating screen drive wheel 5, and a wheel drive mechanism 7. The housing 1 has an opening on the side away from the cooling fan. The upper and lower ends of the opening are rotatably connected to the screen mounting plate 3. The rotating screen 2 is rotatably connected to the mounting hole on the side of the screen mounting plate 3 away from the opening. One end of the rotating screen belt 4 is fitted onto the outer surface of the rotating screen 2, and the other end of the rotating screen belt 4 is fitted onto the rotating shaft drive wheel. The rotating screen drive wheel 5 is connected to the wheel drive mechanism 7, which is connected to one side of the housing 1. The dust removal mechanism 6 is connected to the side of the rotating screen 2 away from the screen mounting plate 3. The rotating screen 2 removes dust through the dust removal mechanism 6.
[0019] Its working principle is as follows: the shell 1, the mesh cover mounting plate 3 and the rotating mesh cover 2 protect the radiator grid inside, preventing dust from falling and dust from splashing when the cooling fan blows air onto the radiator grid. The rotating mesh cover 2 is driven by the wheel drive mechanism 7, the rotating cover drive wheel 5 and the rotating belt to rotate, further preventing dust from accumulating on the rotating mesh cover 2 and in the mesh of the rotating mesh cover 2. The dust removal mechanism 6 can further clean the dust on the rotating mesh cover 2 to prevent it from being blocked and accelerate the discharge of dust from the radiator grid.
[0020] In some embodiments, the dust removal mechanism 6 includes a horizontal suction plate 61 and a brush 62. The horizontal suction plate 61 is connected to the negative pressure side of the housing 1 through a suction pipe 63, and the brush 62 is connected to the side of the horizontal suction plate 61 near the rotating screen 2 and abuts against the rotating screen 2. The horizontal suction plate 61 and the brush 62 rotate relative to the rotating screen 2 to clean the dust on the rotating screen 2.
[0021] In some embodiments, the suction plate has a suction hole at one end near the brush 62, and the suction hole is directly opposite the end of the brush 62 near the rotating mesh cover 2. This ensures that dust inside the rotating mesh cover 2 can be sucked out in time and cleaned by the brush 62.
[0022] In some embodiments, such as Figure 3 As shown, the input end of the suction duct 63 is located at the end of the housing 1 away from the rotating mesh cover 2 and is located on the air intake side of the cooling fan. The cooling fan is located on the side of the heat dissipation grid away from the rotating mesh cover 2. In this way, the suction plate can use the air intake of the cooling fan nearby, and it is convenient to install the suction plate, which can save costs.
[0023] In some embodiments, the wheel drive mechanism 7 includes a first fixed frame 71, a second fixed frame 72, a main drive shaft 73, a pulley 74, and a drive belt 75. The first fixed frame 71 is connected to the side of the housing 1 away from the rotating mesh cover 2, and the second fixed frame 72 is connected to one side of the housing 1. The main drive shaft 73 is rotatably connected between the first fixed frame 71 and the second fixed frame 72. The pulley 74 and the rotating mesh cover drive wheel 5 are respectively connected to both ends of the main drive shaft 73. The pulley 74 is connected to the drive wheel on the engine output shaft via the drive belt 75. The power output from the engine output shaft is transmitted sequentially to the rotating mesh cover drive wheel 5 through the drive wheel, drive belt 75, pulley 74, and main drive shaft 73 to drive the rotating mesh cover drive wheel 5 to rotate. It is conceivable that the above-mentioned wheel drive mechanism 7 can be further modified, such as by adding a protective cover to protect the wheel drive mechanism 7, or by using other power sources such as an electric motor to drive the rotating mesh cover drive wheel 5 to rotate. The main drive shaft 73 can be rotatably connected to the first fixed frame 71 and the second fixed frame 72 via bearings 76.
[0024] In some embodiments, the mesh cover mounting plate 3 is connected to a belt tensioning mechanism 8, which is used to tension the rotating cover belt 4. This can increase the number of times the rotating cover belt 4 can be used and make the rotating mesh cover 2 rotate stably.
[0025] In some embodiments, such as Figure 2 As shown, the belt tensioning mechanism 8 includes a tension spring 81, a first tension wheel 82, a second tension wheel 83, a rotating plate 84, and a spring mounting plate 85. The first tension wheel 82 is rotatably connected to the mesh cover mounting plate 3 and is located on one side of the rotating mesh cover 2. The second tension wheel 83 is rotatably connected to the middle of the rotating plate 84. One end of the rotating plate 84 is rotatably connected to the mesh cover mounting plate 3 and is located below the first tension wheel 82. The other end of the rotating plate 84 is connected to one end of the tension spring 81. The other end of the tension spring 81 is connected to the spring mounting plate 85. The spring mounting plate 85 is connected to the mesh cover mounting plate 3 and is located above the other end of the rotating plate 84. The upper ends of both the first tension wheel 82 and the second tension wheel 83 are connected to the rotating mesh cover belt 4. The first tensioning pulley 82 and the second tensioning pulley 83 abut against the upper and lower belts of the rotating cover belt 4. The elastic potential energy stored in the tensioning spring 81 can drive the second tensioning pulley 83 to rise further when the rotating cover belt 4 is slack, thereby tensioning the rotating cover belt 4.
[0026] In some embodiments, such as Figure 1 As shown, the upper and lower ends of the mesh cover mounting plate 3 near the wheel drive mechanism 7 are equipped with rotating structures, and the mesh cover mounting plate 3 is rotatably connected to the housing 1 through the rotating structures. This allows the mesh cover mounting plate 3 to rotate around the rotating structures at the upper and lower ends, opening like a door.
[0027] In some embodiments, such as Figure 1As shown, the rotating structure is a bolt shaft 9, which is rotatably connected to a bolt shaft 9 hole provided on the housing 1. The bolt shaft 9 is easier to arrange and has a simple structure with low manufacturing cost.
[0028] In some embodiments, such as Figure 1 As shown, the middle part of the dust removal mechanism 6 is connected to the middle part of the mesh cover mounting plate 3. The upper and lower parts of the mesh cover mounting plate 3 near the dust removal mechanism 6 are connected to the housing 1 by means of... Figure 4 The buckle 10 shown is detachable. This allows the dust removal mechanism 6 to move along with the mesh cover mounting plate 3 when it rotates open like a door, facilitating the opening of the mesh cover mounting plate 3 and thus cleaning the dust from the internal radiator grille.
[0029] In some embodiments, such as Figure 2 As shown, the rotating cover drive wheel 5 is installed near the rotating end of the rotating mesh cover 2, and the rotating shaft belt on it can be kept from falling off when the mesh cover mounting plate 3 is rotated open.
[0030] In one specific implementation, see [reference] Figure 1 As shown, the drive belt 75 is mounted on the pulley 74, driving the pulley 74 to rotate. The pulley 74 is fixed on the main drive shaft 73, and both ends of the main drive shaft 73 are fixed on the first fixed bracket and the second fixed bracket respectively via bearings 76. The rotating cover drive wheel 5 is fixed on the main drive shaft 73. The rotating cover belt 4 is mounted on the rotating cover drive wheel 5 and the rotating mesh cover 2. The rotating cover belt 4 is tensioned by the first tension wheel 82 and the second tension wheel 83. The first tension wheel 82 is mounted on the mesh cover mounting plate 3. One end of the spring mounting plate 85 is fixed to the mesh cover mounting plate 3, and the other end is fixed to the rotating plate 84 by a spring. The rotating plate 84 can swing. The pulley 74 drives the rotating cover drive wheel 5 to rotate via the main drive shaft 73. The rotating drive wheel 5 drives the rotating mesh cover 2 to rotate via the rotating mesh cover belt 4. The rotating mesh cover 2 has evenly arranged small holes. The rotating mesh cover 2 is rotatably connected to the connecting shaft 64, which is connected to the mesh cover mounting plate 3. One end of the horizontal suction plate 61 can be fixed to the connecting shaft of the mesh cover mounting plate 3 with bolts. A brush 62 is installed on the horizontal suction plate 61. The horizontal suction plate 61 is connected to the suction pipe 63, which is connected to the radiator suction pipe. The mesh cover mounting plate 3 is rotated on the radiator frame via the bolt shaft 9. Alternatively, it can be fixed in a detachable way. The mesh cover mounting plate 3 is fixed to the radiator frame via the buckle 10. The mesh cover mounting plate 3 can be rotated open by opening the buckle 10.
[0031] During operation, after the engine starts, the engine fan rotates, generating suction to cool the radiator. During this suction process, dust and dirt around the rotating cover are simultaneously drawn into the radiator grille. While the engine fan is generating suction, the suction duct 63 and horizontal suction plate 61 create reverse suction on the rotating cover 2. Combined with the brush 62, this suction removes and cleans away fine dirt that cannot pass through the rotating cover 2 in the area projected by the horizontal suction plate 61. When the harvester has worked all day and the dust and dirt on the radiator grille need to be cleaned, simply open the clip 10 to rotate and open the grille mounting plate 3 for easy and quick cleaning, solving the problem of difficult dust and dirt removal from the radiator grille for harvester users.
[0032] Routine cleaning process: During wheat harvesting, the harvester engine is started. The engine output shaft drives the drive belt 75 to rotate, transmitting power through a B-type V-belt, causing the main drive shaft 73 to rotate at a speed of 150 r / min. The main drive shaft 73 synchronously drives the rotating cover drive wheel 5 to rotate, which in turn drives the rotating mesh cover 2 to rotate clockwise at a speed of 200 r / min through a polyurethane synchronous belt. At the same time, the engine fan starts rotating, generating an airflow of 8000 m³ / h to cool the radiator. During this airflow process, wheat straw fragments, dust, soil particles, and other impurities in the harvester's working environment move towards the radiator with the airflow. Most of the larger particles are blocked by the small holes in the rotating mesh cover 2, while a small amount of fine dirt moves towards the radiator grid with the airflow.
[0033] While the engine fan draws air in, the radiator suction pipe generates negative pressure, which is transmitted to the horizontal suction plate 61 through the suction pipe 63, forming a reverse suction airflow (negative pressure value of approximately -5kPa) between the rotating screen 2 and the horizontal suction plate 61. When the rotating screen 2 rotates to the projection area corresponding to the horizontal suction plate 61, the nylon brush 62 attached to the suction plate combs the dirt on the surface of the screen, cleaning and loosening small dirt (such as wheat husks and fine dust clumps) that are attached to the edges of the holes and cannot pass through holes smaller than φ2mm. At the same time, the reverse suction airflow quickly draws this loosened dirt into the suction holes of the suction plate, and discharges it through the suction pipe 63 and the radiator suction pipe into the harvester's impurity collection box, achieving real-time cleaning of the rotating screen 2, ensuring smooth ventilation of the screen, and guaranteeing the radiator's heat dissipation efficiency. Actual measurements showed that during three consecutive hours of wheat harvesting, the ventilation of the rotating mesh cover 2 remained above 95% of its initial value, and no heat dissipation problems occurred due to mesh cover blockage.
[0034] Post-Day Cleaning Procedure: After the combine harvester completes a day's (approximately 8 hours) of wheat harvesting, the radiator grid surface will be covered with a large amount of wheat straw debris, dust, and other dirt. At this time, there is no need to disassemble other parts. The operator simply needs to manually press the two plastic clips 10 on the mesh cover mounting plate 3 to release the fixing relationship between the mesh cover mounting plate 3 and the radiator frame. Then, push the mesh cover mounting plate 3 to rotate 90° outward around the bolt axis 9 to fully expose the front area of the radiator grid. The operator can use a high-pressure water gun (pressure ≤ 0.8MPa) or a brush to directly clean the radiator grid. After cleaning, rotate the mesh cover mounting plate 3 back to its original position and press the clips 10 to engage and secure it with the clip 10 seat. The entire cleaning process only takes 5-8 minutes.
[0035] Compared to traditional harvesters that require removing 3-5 fixing bolts and spending more than 30 minutes to clean the radiator grille, the structural design of this embodiment significantly shortens the cleaning time and reduces the difficulty of operation. It is especially suitable for time-sensitive scenarios during harvesting operations and effectively solves the core problem of harvester users having difficulty cleaning dust and dirt from the radiator grille and affecting work efficiency when working in the field.
