Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery components, and in particular to a starter housing for agricultural vehicles. Background Technology

[0002] A starter motor, also known as a motor, is the core component for starting an engine. Its working principle involves converting electrical energy from the battery into mechanical energy to overcome the engine's resistance torque and start the engine from a standstill. There are many types of starters, with geared starters being the most widely used. Gear reducers in geared starters come in three different forms: external meshing, internal meshing, and planetary gears. Among these, planetary gear starters are more widely used in the market due to their compact structure, large transmission ratio, and high efficiency.

[0003] Traditional agricultural vehicle starters are mostly made of single-layer cast iron or cast aluminum. In a closed environment, heat accumulates when the motor runs, which can easily lead to coil aging. During field operations, dust can easily enter the housing through the heat dissipation holes, which can aggravate mechanical wear. Under bumpy conditions, the housing is prone to cracking, which can cause oil leaks or short circuits. Although existing technologies have improved the heat dissipation structure, they have not solved the contradiction between dust prevention and heat dissipation. Utility Model Content

[0004] To address the aforementioned technical problems, a starter housing for agricultural vehicles is provided, suitable for starter protection of agricultural vehicles such as tractors and harvesters under harsh working conditions.

[0005] To achieve the above objectives, this utility model discloses a starter housing for agricultural vehicles, comprising a split double-layer housing and a top cover and a tail cover disposed on the front and rear sides of the split double-layer housing. The split double-layer housing includes an outer dustproof housing and an inner heat dissipation housing, with an isolation cavity provided between the outer dustproof housing and the inner heat dissipation housing, the isolation cavity being filled with heat insulation material. A temperature control module and a self-cleaning filter screen disposed on the outer dustproof housing near the tail cover are installed inside the split double-layer housing. An anti-vibration buffer mechanism is provided on the split double-layer housing, and a turbine fan is installed between the outer dustproof housing and the tail cover.

[0006] Furthermore, the outer dustproof shell is made of stamped steel plate, and the surface is coated with a wear-resistant ceramic coating. A spiral guide groove is provided on the top of the outer dustproof shell.

[0007] Furthermore, the inner heat dissipation shell is made of die-cast aluminum alloy, and the inner wall of the inner heat dissipation shell is provided with honeycomb heat dissipation fins. The gaps between the heat dissipation fins are filled with thermally conductive silicone and are tightly attached to the motor stator.

[0008] Furthermore, the temperature control module includes a temperature sensor located on the side of the inner heat dissipation housing near the tail cover, and the temperature sensor is electrically connected to the turbine fan control module located in the tail cover.

[0009] Furthermore, a micro motor is installed on the self-cleaning filter, and the output end of the micro motor is connected to the center of the self-cleaning filter. A dust collection box is installed around the self-cleaning filter, and the dust collection box is fixed to the surface of the outer dustproof shell near the tail cover. The self-cleaning filter is embedded in the groove of the dust collection box, and a dust collection bag is provided inside the dust collection box by means of a snap ring.

[0010] Furthermore, the vibration damping mechanism includes an elastic bracket installed at the connection between the outer dustproof shell and the vehicle body, and a support frame installed inside the split double-layer shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a starter housing for agricultural vehicles, which improves the heat dissipation performance and dust prevention efficiency of the starter, reduces the temperature rise of the motor, and reduces the weight of the housing while ensuring vibration resistance.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the split-type double-layer shell 1 includes an outer dustproof shell 11 and an inner heat dissipation shell 12. An isolation cavity 13 is provided between the outer dustproof shell 11 and the inner heat dissipation shell 12. The isolation cavity 13 is filled with heat insulation material, specifically aerogel heat insulation material, to block the influence of external high temperature on the internal heat dissipation channel. The split-type double-layer shell 1 is equipped with a temperature control module and a self-cleaning filter 4 located near the tail cover 3 on the outer dustproof shell 11. The split-type double-layer shell 1 is equipped with an anti-vibration buffer mechanism. A turbine fan is installed between the outer dustproof shell 11 and the tail cover 3. The temperature control module realizes heat dissipation functions of different intensities. The spiral guide groove and the self-cleaning filter improve the dustproof effect, and the heat dissipation fins and turbine motor improve the heat dissipation effect. The combination of the two realizes the synergistic management of dust and heat, improves the heat dissipation performance and dustproof efficiency of the starter, reduces the temperature rise of the motor, reduces the weight of the shell while ensuring vibration resistance, and is suitable for agricultural operation environments with high dust, high humidity and strong vibration.

[0021] The outer dustproof shell 11 is made of stamped steel plate and coated with a wear-resistant ceramic coating. The surface of the outer dustproof shell 11 is provided with a spiral guide groove 111, which uses the airflow during vehicle movement to guide dust to the outside.

[0022] The inner heat dissipation shell 12 is made of die-cast aluminum alloy. The inner wall of the inner heat dissipation shell 12 is provided with honeycomb heat dissipation fins 121. The gaps between the heat dissipation fins 121 are filled with thermally conductive silicone and are tightly attached to the motor stator.

[0023] The temperature control module includes a temperature sensor located on the side of the inner heat dissipation housing 12 near the tail cover 3. The temperature sensor is electrically connected to the turbine fan control module located in the tail cover 3. When the detected temperature is greater than 85°C, the turbine fan is activated for forced cooling.

[0024] A micro motor 42 is installed on the self-cleaning filter 4. The output end of the micro motor 42 is connected to the center of the self-cleaning filter 4. The adsorbed dust is thrown into the dust collection bag in the dust collection box by centrifugal force. The dust collection box 41 is installed around the self-cleaning filter 4. The dust collection box 41 is fixed to the surface of the outer dustproof shell 11 near the tail cover. The self-cleaning filter 4 is embedded in the groove of the dust collection box 41. The dust collection bag 43 is installed inside the dust collection box 41 by a snap ring.

[0025] The vibration damping mechanism includes an elastic bracket 5 located at the connection between the outer dustproof shell 11 and the vehicle body, and a support frame located inside the split double-layer shell 1, forming a double buffer structure to adapt to complex working conditions such as farmland gravel roads and muddy ground lights. Specifically, a damping adjustment device is installed at the bottom of the elastic bracket, and a rubber and metal composite bushing structure is set on the outside of the adjustment device to realize three-way damping coefficient adjustment and reduce high-frequency vibration transmission. The support frame is made of glass fiber nylon mesh, and triangular reinforcing ribs are set at key stress points to improve impact resistance.

[0026] The working principle of this embodiment is as follows: the inner heat dissipation shell is fixed to the motor assembly with quick-release bolts, the outer dustproof shell is snapped on after filling with aerogel, and the surrounding waterproof sealing strip is locked. Under normal operating conditions, heat dissipation is achieved by natural airflow through the spiral guide groove, and the self-cleaning filter removes dust. Under high-temperature operating conditions, the temperature control system starts the turbine fan to improve the cooling effect. The dust collection box is disassembled regularly, and the internal dust collection bag is replaced to remove accumulated dust.
