Description

Background Art

The cooling system is an important part to ensure the normal operation of various vehicles. It is used to keep the engine within the appropriate temperature range under all working conditions. Generally, the water-cooled cooling system includes a radiator, a fan, a water pump, etc., among which the radiator can be integrated with a water tank, an intercooler and a hydraulic oil radiator to reduce the heat load of the engine and other related working parts.

With the development of agricultural technology, the use of high-power agricultural machinery such as large-feed sugarcane harvesters is becoming more and more common. The radiators they are equipped with are usually large in size, and in order to ensure the economy and good heat dissipation effect of heat dissipation, such agricultural machinery generally adopts independent heat dissipation. However, the vibration of the engine and the vibration of the independent cooling fan cause obvious vibration of the whole machine, which puts forward higher requirements for radiator vibration reduction to avoid radiator welding and water leakage.

Typically, the radiator is installed in the engine compartment, and a rubber pad or other shock-absorbing pad is set at the connection position therebetween, and the side is fixed by a tie rod or a bracket to prevent shaking, but this installation structure still cannot meet the vibration reduction needs of the radiator well.

DETAILED DESCRIPTION

The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside and outside" refer to inside and outside relative to the outline of each component itself.

Referring to Figures 1 to 7, one aspect of the utility model provides a vibration reduction mounting structure of a cooling system, including a radiator frame 1, a radiator 3 and a fan 4, wherein the outer side of the radiator frame 1 may be provided with a muffler covered by a muffler shield (not marked). The radiator 3 is used to dissipate the heat carried by the coolant into the atmosphere to reduce the temperature of the coolant. Specifically, the radiator 3 may include parts such as a water storage chamber and a radiator core, and the coolant may flow in the radiator core of the radiator 3, and air may pass outside the radiator core, and the hot coolant may be cooled by dissipating heat to the air. As the core part for realizing heat exchange between the coolant and the air, the radiator core may be formed into a variety of structural forms, such as a tube-fin radiator, a tube-belt radiator, and the like.

The fan 4 is configured to blow air toward the radiator 3 to remove the heat emitted by the radiator 3. As mentioned above, the air exchanges heat with the coolant in the radiator to cool the coolant, and the fan 4 can increase the air flow rate flowing through the radiator core to enhance the heat dissipation capacity of the radiator 3 and accelerate the cooling of the coolant.

During operation, due to the vibration of the engine and the vibration of the fan 4, the radiator 3 is easily welded and leaked, which affects the service life. Therefore, it is necessary to perform vibration reduction design on the radiator 3. Different from the above-mentioned prior art, the vibration reduction mounting structure of the utility model arranges the radiator 3 in the radiator frame 1 and is fixed to the radiator frame 1, and the bottom of the radiator frame 1 is provided with a plurality of vibration reduction units 2 for connecting to a frame such as a vehicle chassis (engine compartment).

Therefore, compared with the installation method of directly installing the radiator in the engine compartment through rubber pads or other shock-absorbing pads, and fixing it through a pull rod or bracket to prevent shaking, the vibration of the engine needs to pass through the vibration reduction unit 2 and the radiator frame 1 to be transmitted to the radiator 3, thereby extending the vibration propagation path. In addition, this vibration reduction installation structure can use the relatively large bottom area of the radiator frame 1 to increase the vibration reduction connection contact area with the frame, thereby reducing the impact of engine vibration on the radiator 3 and effectively ensuring the vibration reduction effect of the radiator 3. In addition, since the radiator 3 is fixed to the radiator frame 1, the radiator 3 can be assembled to the vehicle body together with the radiator frame 1 during production to achieve modular assembly, which is conducive to improving production efficiency. This vibration reduction installation structure of the cooling system is particularly suitable for high-power agricultural machinery such as large-feed sugarcane harvesters, and can effectively reduce the risk of radiator welding and water leakage.

In a preferred embodiment, the radiator frame 1 can be installed with an air inlet mesh assembly 5 and an air outlet mesh assembly 6 that are arranged opposite to each other, and the air inlet mesh assembly 5 and the air outlet mesh assembly 6 are respectively located on the front and rear sides of the radiator 3, and the fan 4 is installed to be located between the air inlet mesh assembly 5 and the radiator 3. Thus, under the action of the fan 4, air is sucked into the radiator frame 1 from the air inlet mesh assembly 5 to form an airflow, and the airflow flows through the radiator 3 and can exchange heat with the coolant therein, and then the hot air after the heat exchange can be discharged through the air outlet mesh assembly 6. The air inlet mesh assembly 5 and the air outlet mesh assembly 6 can prevent debris from entering the radiator frame 1, ensuring that the radiator 3 can reliably exchange heat. The radiator 3 is arranged in the overall frame, and the aforementioned air inlet mesh assembly 5 and the air outlet mesh assembly 6 are provided, which can effectively reduce the turbulence of the inlet and outlet air.

In order to further buffer the vibration from the engine and the fan 4 transmitted by the radiator frame 1, the bottom of the radiator 3 can be supported on the radiator frame 1 by the first rubber block 7, thereby reducing the impact of the vibration of the fan 4 on the radiator 3 and the entire machine.

In addition, a sealing sponge may be provided between the top surface and/or the side surface of the radiator 3 and the inner wall surface of the radiator frame 1. For example, a sealing sponge may be attached to the inner wall surfaces of the top plate and the side plate of the radiator frame 1 to form a seal between the radiator 3 and the radiator frame 1, thereby ensuring the ventilation efficiency of the airflow passing through the radiator 3 and achieving good noise reduction and sound insulation effects.

Generally, the fan 4 can be configured to be driven by a hydraulic motor, and a proportional valve can be provided in the corresponding hydraulic circuit to control the rotation speed of the fan 4 as required. For example, the water temperature signal sensed by the temperature sensor can be fed back to the proportional valve. When the water temperature is high, the proportional valve is controlled to increase the rotation speed of the hydraulic motor, thereby increasing the rotation speed of the fan 4; when the water temperature is low, the proportional valve is controlled to reduce the rotation speed of the hydraulic motor, thereby reducing the rotation speed of the fan 4. In addition, when the air inlet mesh assembly 5 is blocked by debris as described above, the radiator 3 cannot dissipate heat in a timely and effective manner, resulting in an increase in water temperature. At this time, the fan 4 can be controlled to reverse to blow off the debris attached to the air inlet mesh assembly 5, thereby ensuring that air can be sucked into the radiator frame 1 through the air inlet mesh assembly 5 and blown to the radiator 3.

When the fan 4 back-blows the blocked air inlet mesh assembly 5, the fan 4 may vibrate relatively violently. This vibration combined with the vibration of the engine will increase the risk of open welding of the radiator 3. In addition, the vibration of the fan 4 may cause the airflow blown by it to fail to effectively flow through the radiator 3, affecting the heat dissipation efficiency. To this end, in the preferred embodiment shown in the figure, the fan 4 is not only arranged in the radiator frame 1, but also fixed to the radiator frame 1 through a fan mounting bracket 8 connected to the radiator frame 1, and installed to face the radiator 3. As a result, the radiator 3 and the fan 4 are fixed on a common mounting base (i.e., the radiator frame 1), which can effectively ensure that the airflow blown by the fan 4 flows through the radiator 3. In addition, the fan 4 and the radiator 3 can be assembled to the vehicle body together with the radiator frame 1 to achieve modular assembly, which is conducive to improving production efficiency.

Furthermore, the radiator frame 1 may be provided with a mounting beam 11 for connecting the fan mounting bracket 8 , and a second rubber block 9 is provided between the fan mounting bracket 8 and the mounting beam 11 , thereby further preventing the vibration of the fan 4 from being transmitted to the radiator frame 1 and the radiator 3 .

As mentioned above, the utility model forms an integral frame structure by fixing the radiator 3 to the radiator frame 1, and uses a plurality of vibration reduction units 2 arranged at the bottom of the radiator frame 1 to reduce the influence of engine vibration on the radiator, thereby achieving a secure installation and a good vibration reduction effect. Typically, three or four vibration reduction units 2 may be arranged at the bottom of the radiator frame 1. The vibration reduction unit 2 may be arranged in a variety of suitable structures.

FIG5 shows an enlarged structure of a vibration reduction unit 2, and one or more vibration reduction units 2 in the above vibration reduction installation structure can adopt this structure. The vibration reduction unit 2 includes a mounting plate 21 formed with a mounting hole, a first buffer 22 extending from one side of the mounting plate 21 through the mounting hole to the other side, a second buffer 23 provided on the other side of the mounting plate 21, and a fastener 24 extending through the first buffer 22 and the second buffer 23. The mounting plate 21 can be a U-shaped member fixed (such as welded) to the bottom plate of the radiator frame 1, and the first buffer 22 and the second buffer 23 can be set as a rubber member, which is fixed to the mounting hole of the mounting plate 21 by fasteners 24 such as bolts, nuts and washers, and plays a vibration reduction role between the mounting plate 21 and the connected frame. By providing the first buffer 22 and the second buffer 23, the assembly of the vibration reduction unit 2 can be easily completed. Furthermore, since the first buffer member 22 extends through the mounting hole of the mounting plate 21, it can not only buffer vibration in the vertical direction, but also reduce the transmission of vibration in the horizontal direction by using the portion passing through the mounting hole.

Here, the first buffer 22 can be formed into a step-like structure with a radial dimension decreasing in the direction toward the second buffer 23. The second buffer 23 can be sleeved on the portion of the first buffer 22 extending to the other side of the mounting plate 21, thereby the two can be relatively firmly connected to each other and reliably buffer vibration. In addition, the portion of the first buffer 22 passing through the mounting hole can be sleeved with a cushion component 25, and the cushion component 25 is at least partially located in the annular gap between the mounting plate 21 and the first buffer 22, thereby allowing the first buffer 22 and the mounting hole to have a relatively large difference in radial dimension, reducing the requirements for dimensional accuracy.

On the basis of the above-mentioned vibration reduction mounting structure, another aspect of the utility model provides an agricultural machine having the vibration reduction mounting structure of the cooling system, wherein the radiator frame 1 is connected to the vehicle chassis through a plurality of vibration reduction units 2, such as being installed in the engine compartment, thereby, the radiator 3 can be installed together with the radiator frame 1, and can effectively reduce the influence of engine vibration on the radiator, thereby ensuring the vibration reduction effect of the radiator. In particular, the agricultural machine can be a sugarcane harvester.

The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
