Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a noise reduction and heat dissipation structure of engineering machinery. Background Art

[0002] Currently, most loader engines are semi-enclosed, directly exposed to the outside world and making a lot of noise. Furthermore, construction machinery often operates in harsh conditions, with the engine and radiator in direct contact with the outside air, which can easily accumulate dust and affect heat dissipation efficiency.

[0003] Based on the above problems, the utility model provides a noise reduction and heat dissipation structure for engineering machinery, which can improve the heat dissipation effect; at the same time, it constructs a closed space to accommodate the engine, thereby improving the noise reduction effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to design a noise reduction and heat dissipation structure for engineering machinery, which can improve the heat dissipation effect and noise reduction effect of the noise reduction and heat dissipation structure for engineering machinery.

[0005] In order to solve the above technical problems, the noise reduction and heat dissipation structure of engineering machinery of the present invention includes a hood, a frame is installed under the hood, a counterweight is installed behind the frame, and the counterweight is arranged under the hood. The frame includes two symmetrical and vertically arranged brackets on the left and right sides, and the upper parts of the two brackets are respectively connected to the front of the left and right sides of the hood. A radiator is installed between the two brackets, and the radiator is arranged in the hood. The hood includes a fixedly installed hood frame welded and a hood body hinged to the hood frame welded. Its structural feature is that the upper end of the radiator is connected to the hood frame welded, a first windshield rubber plate is arranged between the lower side of the radiator and the frame, and two second windshield rubber plates are respectively arranged between the left and right sides of the radiator and the left and right sides of the hood.

[0006] The above structure improves the noise reduction effect by making the frame, hood, counterweight and radiator jointly construct an enclosed space for accommodating the engine; a windshield rubber plate is installed around the radiator, and the windshield rubber plate and the hood above the radiator jointly isolate the air on the front and rear sides of the radiator, so that the hot air flowing out of the radiator will not flow back, thereby improving the heat dissipation effect.

[0007] Preferably, two side doors are respectively opened on the left and right sides of the hood frame, and the two side doors are close to the two sides of the radiator. The setting of the side doors makes it convenient to clean the radiator.

[0008] Preferably, a first window is opened in the welded middle part of the hood frame, and an upper skylight is opened on the upper part of the hood body near the first window. The first window and the upper skylight are adjacent to each other, and the operator can open both together to enhance the heat dissipation effect.

[0009] Preferably, the hood frame is welded with two second windows symmetrically located on the left and right sides of the first window, and the hood frame is further welded with two third windows located above the two side doors. The arrangement of the two second windows and the third window can further enhance the heat dissipation effect.

[0010] Preferably, a rear window is provided at the rear of the hood body, which can effectively improve the heat dissipation effect.

[0011] Preferably, a plurality of ventilation holes are evenly opened on the two side doors, the two first windows, the two second windows, the third window, the upper skylight and the rear window, and the ventilation holes are arranged in a regular hexagonal structure. The regular hexagonal ventilation hole structure can better improve the heat dissipation effect.

[0012] Preferably, a vent is defined at the bottom of the counterweight, communicating with the cavity within the hood. A counterweight cover is provided at the vent, which is provided with a plurality of louvered ventilation openings. The vent connects to the cavity within the hood, allowing heat generated by the engine within the hood to be dissipated. The provision of the louvered ventilation opening structure improves heat dissipation.

[0013] Preferably, the upper end of the radiator is tilted backward, and the radiator fan is arranged near the rear and facing the louver air vents on the counterweight cover. The fan can blow out the heat emitted by the radiator in the hood from the louver air vents, greatly improving the heat dissipation effect.

[0014] In summary, the beneficial effects of the present invention are:

[0015] The frame, hood, counterweight and radiator together construct an enclosed space to accommodate the engine, which improves the noise reduction effect; the windows on the hood all adopt a regular hexagonal air vent structure, and the counterweight cover adopts a louver air vent structure, which improves the heat dissipation effect; windshield rubber plates are installed around the radiator, which together with the hood relatively isolate the air on the front and rear sides of the radiator, ensuring that the hot air sucked out of the radiator by the fan will not flow back, thereby improving the heat dissipation effect; the radiator is placed at an angle, and the fan is facing the louver air vents on the counterweight, which improves the heat dissipation effect.

[0027] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0028] Refer to the attached Figure 1 The utility model discloses a noise reduction and heat dissipation structure for engineering machinery, which includes a hood 1 and a frame 2 installed below the hood 1. A counterweight 3 is installed behind the frame 2. The counterweight 3 is arranged below the hood 1. Figure 5 As shown, the frame 2 includes two brackets 4 that are symmetrical and vertically arranged on the left and right sides. The upper parts of the two brackets 4 are respectively connected to the front parts of the left and right sides of the hood 1. A radiator 5 is installed between the two brackets 4. The radiator 5 is arranged in the hood 1. The hood 1 includes a fixed hood frame weld 6 and a hood body 7 hinged to the hood frame weld 6. The upper end of the radiator 5 is connected to the hood frame weld 6, so that the frame 2, a part of the hood 1, the counterweight 3, and the radiator 5 together construct a closed space for accommodating the engine, avoiding direct contact between the engine and the external environment, thereby improving the noise reduction effect and preventing the accumulation of dust from affecting the heat dissipation efficiency. Figure 3 As shown, a first windshield rubber plate 8 is provided between the lower side of the radiator 5 and the vehicle frame 2, and two second windshield rubber plates 9 are provided between the left and right sides of the radiator 5 and the left and right sides of the hood 1 respectively. The upper end of the radiator 5 is tilted backward. When the engine works for a long time, a large amount of heat will be generated. This heat will be dissipated into the air through the radiator 5. The fan 18 on the radiator 5 generates wind and takes away the heat dissipated by the radiator 5, thereby cooling and dissipating the heat. The radiator 5 absorbs and transfers the heat generated by the engine through the circulation of coolant (such as water or other special liquids). The coolant circulates inside the engine, absorbs the heat, and then flows through the radiator 5. Heat exchange is performed with the outside air through the radiator 5 to dissipate the heat into the environment. The working principle of the radiator 5 is the existing technology and will not be repeated here. Two second windshield rubber plates 9 are installed on the left and right sides of the radiator 5, and a first windshield rubber plate 8 is installed on the bottom. The upper end of the radiator 5 is connected to the hood frame welding 6, so that the cold air on the front side of the radiator 5 and the hot air on the rear side are relatively isolated, ensuring that the hot air sucked out of the radiator 5 by the fan 18 will not flow back, and the hot air on the rear side can be quickly discharged, ensuring the heat dissipation efficiency of the radiator 5, thereby improving the heat dissipation effect.

[0029] As a further explanation of this embodiment, refer to the attached Figure 1 , two side doors 10 are respectively opened on the left and right sides of the hood frame welding 6, and the two side doors 10 are respectively close to the two sides of the radiator 5. When the radiator 5 needs to be cleaned of dust, the side door 10 can be opened to clean the dust on the radiator 5, thereby avoiding the influence of dust accumulation on the radiator 5 on the heat dissipation efficiency. In addition, there is no need to disassemble the machine, which is time-consuming and laborious.

[0030] As a further explanation of this embodiment, refer to the attached Figure 1A first window 11 is provided in the middle of the hood frame weld 6, and an upper skylight 14 is provided on the upper part of the hood body 7 near the first window 11. Two second windows 12 are symmetrically provided on the hood frame weld 6 on the left and right sides of the first window 11. The hood frame weld 6 is also provided with two third windows 13 respectively located above the two side doors 10. A number of air holes are evenly provided on the two side doors 10, the two first windows 11, the two second windows 12, the third window 13, the upper skylight 14 and the rear windshield 15, and the air holes are arranged in a regular hexagonal structure, which greatly improves the heat dissipation effect.

[0031] As a further explanation of this embodiment, refer to the attached Figure 4 A vent is provided at the bottom of the counterweight 3, which is connected to the cavity inside the hood 1. A counterweight cover 16 is provided at the vent. The counterweight cover 16 is provided with a number of louver air vents 17. The fan 18 of the radiator 5 is arranged near the rear and facing the louver air vents 17 on the counterweight cover 16. The fan 18 discharges the heat emitted by the radiator 5 through the louver air vents 17, thereby accelerating the discharge of hot air in the cavity.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
