Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery radiators, in particular to a dust removal device for a radiator cover of a rotary harvester. Background Art

[0002] There is a lot of dust and grass clippings in the working environment of the harvester. Most of the existing harvester radiator covers do not have reliable dust removal devices. The radiator cover is often blocked by straw and dust during operation. If it is not cleaned in time, it will cause the machine to heat up, and in severe cases, it will cause the engine to pull the cylinder and burn the tile. There are currently two solutions to this problem. One is that the driver cleans it by hand when putting grain. Generally, the radiator cover of the harvester is installed next to the cab. For harvesters without a cab, the driver can reach out and use his hand to assist in sweeping the dust, but it is easy to cause safety accidents. For drivers with cabs, the driver must get off the car to remove dust. When the cab door is opened, the temperature of the cab immediately rises, and a large amount of dust enters the cab during the cold and hot exchange, reducing the use effect of the air conditioner, especially when getting off the car to remove dust. If you encounter a very dangerous harvester that slips in neutral, it will cause a serious safety accident. Secondly, the driver gets off the car to remove dust, which wastes working time and reduces the work efficiency of the harvester. Another method is to blow dust by reversing the engine. This technology has good dust removal effect, but only a few engine manufacturers can achieve engine fan reversal technology. When the assembly plant uses this technology, it undoubtedly increases the cost and the user's purchase cost. In addition, this technology is not easy to modify for old harvesters and cannot solve the high temperature problem of old machines. Utility Model Content

[0003] The utility model aims to provide a dust removal device for a radiator cover of a rotary harvester, which has the effect of stable and automatic dust removal.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a rotary harvester radiator cover dust removal device, including a fixed plate, a motor is fixed in the middle of the fixed plate, an output gear is fixed at the output end of the motor, the output gear is located between the motor and the fixed plate, a mounting plate is fixed to the fixed plate, a transmission shaft rotates on the mounting plate, dust removal blades are fixed on the transmission shaft, and the motor drives the dust removal blades to rotate through the output gear.

[0005] By adopting the above technical solution, the fixing plate is installed on the inner cover of the radiator by welding or fasteners. When the harvester is working, the motor is started, and the motor drives the dust removal blades to rotate through the output gear. During the rotation of the dust removal blades, the wind pressure difference causes the straw, dust, etc. adsorbed on the outer cover of the radiator to fall off, thereby achieving a dust removal effect.

[0006] The utility model is further configured as follows: a driven gear meshing with the output gear is fixed to one end of the transmission shaft close to the motor, and an end of the transmission shaft away from the driven gear is fixedly connected to the dust removal blade.

[0007] By adopting the above technical solution, the motor drives the output gear to rotate, and the output gear drives the driven gear to rotate. The driven gear drives the dust removal blades to rotate synchronously through the transmission shaft, so that the rotation center of the dust removal blades and the engine fan blade installation center are on the same axis. During the rotation of the dust removal blades, the wind pressure difference causes the straw, dust, etc. adsorbed on the radiator cover to fall off, thereby achieving a dust removal effect.

[0008] The utility model is further configured as follows: a gear ring meshing with the output gear is fixed to one end of the transmission shaft close to the motor through a plurality of connecting frames, and an end of the transmission shaft away from the output gear is fixedly connected to the dust removal blade.

[0009] By adopting the above technical solution, the motor drives the output gear to rotate, so that the output gear drives the ring gear to rotate, and the ring gear drives the dust removal blades to rotate synchronously through the transmission shaft, so that the dust removal blades are more stable and not deformed.

[0010] The utility model is further configured as follows: the dust removal blade is provided with transmission teeth meshing with the output gear along the circumferential direction, and a plurality of air holes are opened on the dust removal blade.

[0011] By adopting the above technical solution, the motor drives the output gear to rotate, and the output gear directly drives the dust removal blades to rotate synchronously through the transmission teeth, thereby achieving automatic dust removal and making the dust removal blades more stable and not deformed.

[0012] The utility model is further configured as follows: the air holes are configured as circular holes.

[0013] By adopting the above technical solution, air holes are added as needed to increase air flow and effectively remove dust.

[0014] The utility model is further configured as follows: the air holes are configured as fan-shaped holes.

[0015] By adopting the above technical solution, air flow is increased and dust is effectively removed.

[0016] The utility model is further configured as follows: a shaft retaining ring is installed at the end of the transmission shaft to fix the dust removal blade to the mounting plate.

[0017] By adopting the above technical solution, it is convenient to install and fix the dust removal blades, and it is also convenient to modify the dust removal blades according to needs.

[0018] The utility model is further configured as follows: baffles in the same direction as the motor are vertically fixed at both ends of the fixing plate, a connecting plate is vertically fixed at one end of the baffle away from the fixing plate, and a mounting hole is provided on the connecting plate.

[0019] By adopting the above technical solution, the fixing plate can be installed on the inner cover of the radiator by welding or fasteners. The baffle is used to create a gap between the fixing plate and the inner cover of the radiator to accommodate the motor. When installing with fasteners, the fasteners are passed through the mounting holes to relatively fix the connecting plate and the fixing plate to the inner cover of the radiator, which facilitates modification and reduces costs, and is safer and more reliable.

[0020] The beneficial effects of the utility model are:

[0021] 1. Install the fixing plate on the inner cover of the radiator by welding or fasteners. When the harvester is working, start the motor, and the motor drives the dust removal blades to rotate through the output gear. During the rotation of the dust removal blades, the wind pressure difference causes the straw, dust, etc. adsorbed on the outer cover of the radiator to fall off, thereby achieving a dust removal effect;

[0022] 2. Install the fixing plate on the inner cover of the radiator by welding or fasteners. The baffle is used to create a gap between the fixing plate and the inner cover of the radiator to allow the motor to pass through. When installing with fasteners, pass the fasteners through the mounting holes to relatively fix the connecting plate and the fixing plate to the inner cover of the radiator. At the same time, use shaft retaining rings to relatively fix the dust removal blades and the drive shaft, which facilitates modification and reduces costs, and is safer and more reliable.
