TECHNICAL FIELD

[0001] The application relates to the technical field of agricultural machinery, in particular to an electric direct-drive self-propelled roller. BACKGROUND

[0002] As an important agricultural machine, the roller is widely used in the field of soil treatment. Its main functions are to compact soil, level the ground surface, and promote the close contact between seeds and soil, thereby improving the emergence rate and growth quality of crops. With the continuous improvement of agricultural mechanization level, the application range of the roller in agricultural production is gradually expanding, which plays an important role in improving agricultural production efficiency, reducing labor intensity and improving farmland environment. However, the power source and technical structure of the traditional roller are facing new challenges, especially the increasing demand for environmental protection and energy saving.

[0003] At present, the traditional roller usually adopts a diesel engine as a power source. The diesel engine driven roller mainly includes a machine body, a diesel engine driving system, a transmission system, a walking system (including driving wheels and a steering mechanism), a roller drum and other components. The power is transmitted to the walking system and the roller drum through the transmission system to realize the movement and operation of the equipment. In order to meet different operation requirements, the industry generally adopts various technical means, such as optimizing the gear ratio of the transmission system to improve the power transmission efficiency, or improving the combustion performance of the diesel engine to reduce fuel consumption and emissions. However, the diesel engine driven roller still has obvious shortcomings, such as high noise, high pollution and high maintenance cost, which cannot meet the requirements of modern agriculture for environmental protection and high efficiency. CONTENT OF THE INVENTION

[0004] In order to make the roller run environmentally, low noise and high efficiency, the application provides an electric direct-drive self-propelled roller.

[0005] The electric direct-drive self-propelled roller provided by the application adopts the following technical scheme:

[0006] An electric direct-drive self-propelled roller, comprising a machine body, at least two driving wheels arranged on the machine body, a transmission system connecting the driving wheels, a roller drum arranged on the machine body, and a steering mechanism arranged on the machine body for controlling the steering of the driving wheels and the roller drum; further comprising:

[0007] A storage battery arranged on the machine body;

[0008] An electric motor arranged on the machine body and connected to the storage battery;

[0009] A gearbox arranged on the machine body, an input shaft of the gearbox being connected to an output shaft of the electric motor, and an output shaft of the gearbox being connected to the transmission system;

[0010] The heat dissipation device is arranged between the battery and the machine body and is used for heat dissipation treatment of the battery, comprising a heat dissipation shell sleeved outside the battery, an air inlet channel and an air outlet channel respectively fixed on both sides of the heat dissipation shell, wherein the heat dissipation shell is fixedly connected with the machine body, and the inner wall of the heat dissipation shell is arranged in a spaced manner with the battery.

[0011] By adopting the above technical scheme, the motor is connected with the gearbox, and then combined with the transmission system to drive the rolling cylinder and the driving wheel to rotate, so that direct connection driving is realized. The use of the motor instead of the traditional diesel engine as a power source not only improves the efficiency of power transmission, significantly reduces the noise and pollution emission during equipment operation, but also makes the overall structure more compact, reduces energy loss and maintenance cost. In addition, the heat dissipation device is arranged to effectively dissipate heat of the battery, improve the stable operation of the battery in a high temperature environment, maintain the stable performance of the equipment during long time operation, and improve the working efficiency and reliability of the roller.

[0012] Optionally, the heat dissipation shell is internally provided with an upper branch heat dissipation air duct, an intermediate branch heat dissipation air duct and a lower branch heat dissipation air duct from top to bottom, and the upper branch heat dissipation air duct, the intermediate branch heat dissipation air duct and the lower branch heat dissipation air duct are in communication with the air inlet channel and the air outlet channel.

[0013] By adopting the above technical scheme, the layered design of the upper branch heat dissipation air duct, the intermediate branch heat dissipation air duct and the lower branch heat dissipation air duct enables the airflow to realize full coverage in the heat dissipation shell. The multi-layer branch heat dissipation air duct forms an efficient heat dissipation network, so that the heat generated by the battery during operation can be uniformly and quickly dissipated, reducing the occurrence of local overheating, prolonging the service life of the battery and improving the overall stability of the equipment.

[0014] Optionally, the air inlet channel is provided with a suction fan, and the air outlet channel is provided with an exhaust fan.

[0015] By adopting the above technical scheme, the suction fan can introduce external cold air into the heat dissipation shell to accelerate air circulation and reduce the temperature of the battery. The exhaust fan can quickly exhaust the hot air in the heat dissipation shell to improve the heat dissipation efficiency and ensure that the battery operates within a suitable working temperature range.

[0016] Optionally, the upper branch heat dissipation air duct, the intermediate branch heat dissipation air duct and the lower branch heat dissipation air duct all extend into the air inlet channel, and the suction fan is located at the extension end of the upper branch heat dissipation air duct, the intermediate branch heat dissipation air duct and the lower branch heat dissipation air duct.

This reduces the occurrence of local overheating of the battery due to uneven distribution of cold airflow and improves the operational stability of the battery.

[0018] Optionally, the air intake channel is arranged vertically, and the air inlet of the air intake channel is located at the top.

[0019] By adopting the above technical solution, the vertically arranged air intake channel can form a good air circulation path, which is conducive to the entry of cold air from the top and its downward flow, thereby improving heat dissipation efficiency. At the same time, the air inlet being located at the top can also reduce the entry of ground dust and impurities, keep the heat dissipation device clean, and improve the heat dissipation performance and stability of the heat dissipation device.

[0020] Optionally, an air hood and a rain shield are fixedly provided at the top of the air duct.

[0021] By adopting the above technical solutions, the air hood helps to guide external air into the air intake channel, increasing the air intake volume of the air intake channel, thereby enhancing the heat dissipation effect on the battery. At the same time, the air hood and rain shield can also prevent rainwater from entering the air intake channel, reducing the risk of damage to the heat dissipation device and battery due to rainwater intrusion.

[0022] Optionally, a filter screen is fixed inside the air hood, and the filter screen is inclined.

[0023] By adopting the above technical solutions, the filter screen can reduce the entry of external dust and impurities into the air intake channel, making the inside of the heat dissipation system less susceptible to contamination and improving the stability of the heat dissipation effect; the inclined filter screen helps to reduce dust accumulation and reduce the frequency of filter screen maintenance.

[0024] Optionally, the heat dissipation housing is provided with an inspection door, and a locking element for fixing the inspection door is provided between the inspection door and the heat dissipation housing.

[0025] By adopting the above technical solution, the access door facilitates regular inspection and maintenance of the battery and related components inside the heat dissipation casing. A locking device is installed between the access door and the heat dissipation casing to keep the access door tightly closed when not under maintenance, preventing external dust, moisture and other impurities from entering the heat dissipation casing and improving the operational stability and service life of the battery.

[0026] Optionally, heat dissipation fins are fixedly provided on both the heat dissipation housing and the outside of the inspection door.

[0027] By adopting the above technical solution, the heat sink can increase the heat dissipation area of ​​the heat dissipation shell, improve heat dissipation efficiency, and reduce the temperature of the battery.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Replacing traditional diesel engines with electric motors and batteries as power sources improves power transmission efficiency, significantly reduces noise and pollution emissions during equipment operation, and makes the overall structure more compact, reducing energy loss and maintenance costs, thus meeting the requirements of modern agriculture for environmental protection and high efficiency.

[0030] 2. By installing a heat dissipation device to effectively cool the battery, the stable operation of the battery in high-temperature environments is improved, enabling the equipment to maintain stable performance during long-term operation and improving the working efficiency and reliability of the ballast machine;

[0031] 3. The direct connection between the electric motor and the gearbox simplifies the transmission structure, improves energy transfer efficiency, and reduces maintenance costs;

[0032] 4. The heat dissipation device is designed with multi-branch heat dissipation air ducts and air intake channels, which enables airflow to cover the heat dissipation shell in all directions. The multi-layer branch heat dissipation air ducts form an efficient heat dissipation network, which allows the heat generated by the battery during operation to be dissipated evenly and quickly, reducing the occurrence of local overheating, extending the service life of the battery and improving the overall stability of the equipment.

[0033] 5. The upper branch cooling duct, middle branch cooling duct, and lower branch cooling duct extend into the air intake channel, enabling the cooling duct to form a more uniform airflow distribution of the introduced cold air, which enters the upper branch cooling duct, middle branch cooling duct, and lower branch cooling duct respectively. This reduces the occurrence of local overheating of the battery due to uneven distribution of cold air and improves the operational stability of the battery. Attached Figure Description

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative contribution fall within the scope of protection of the present application.

[0042] The embodiments of the present application disclose an electric direct-drive self-propelled roller.

The electric motor 6 and the gearbox 7 are detachably installed on the machine body 1 by bolts, etc., and the output shaft of the electric motor 6 is directly connected with the input shaft of the gearbox 7; the output shaft of the gearbox 7 transmits power to the drive wheels 2 through the transmission system to realize the movement of the roller. The heat dissipation device 8 is arranged between the storage battery 5 and the machine body 1 and is used for heat dissipation treatment of the storage battery 5, comprising a heat dissipation shell 81 sleeved on the outer side of the storage battery 5, an air inlet channel 82 and an air outlet channel 83 respectively fixed on both sides of the heat dissipation shell 81, wherein the heat dissipation shell 81 is fixedly connected with the machine body 1, and the inner wall of the heat dissipation shell 81 is arranged in space with the storage battery 5 to form an air flow space.

[0043] Specifically, referring to Figure 2 and Figure 3The heat dissipation shell 81 is made of high-temperature-resistant and corrosion-resistant aluminum alloy material, and the surface is treated by anodic oxidation, which has good heat conduction performance and durability.

The multi-layer air duct arrangement can ensure that the cold air enters from the top and is evenly distributed in the entire heat dissipation shell 81, improving the heat dissipation efficiency. For example, the upper branch heat dissipation air duct 821 is mainly used for cooling the upper region of the battery 5, the middle branch heat dissipation air duct 822 is responsible for heat dissipation of the middle region, and the lower branch heat dissipation air duct 823 is used for heat dissipation of the bottom region.
