Embodiment 1

[0030] see Figure 1-5According to an embodiment of the present invention, a diesel engine with a protective mechanism for agricultural machinery includes a support plate 1, a sub-support plate 2 is provided on the top of the support plate 1, and a diesel engine 10 is placed on the top of the sub-support plate 2 , a damping mechanism is provided between the supporting plate 1 and the auxiliary supporting plate 2, the damping mechanism includes a spring 3, the top end of the spring 3 is fixedly provided with an upper threaded plate 4, and the bottom end of the spring 3 is fixed A lower threaded plate 5 is provided, the upper threaded plate 4 and the lower threaded plate 5 are respectively fixed on the support plate 1 and the auxiliary support plate 2 by screws, and the spring 3 is sleeved with a telescopic bellows 6. The top of the telescopic bellows 6 is fixed with an upper circular plate 7, the bottom of the telescopic bellows 6 is fixed with a lower circular plate 8, and bot...

Embodiment 2

[0032] see figure 1 , for the battery box 13, a box door is installed on the battery box 13, and the wires on the battery 14 pass through the auxiliary support plate 2 and extend to the inside of the protective cover 17 to connect with the motor 16 , the outer wall of the protective cover 17 is fixed with a mounting plate, and the mounting plate is fixed on the top of the auxiliary support plate 2 by screws.

Embodiment 3

[0034] see figure 1 and Figure 4 , for the wind cover 19, the wind cover 19 is provided with a sound insulation mechanism, the sound insulation mechanism includes an inner cover 30 and an outer cover 31, and a sound absorption cavity 32 is formed between the inner cover 30 and the outer cover 31. The inner side of the inner cover 30 is fixed with a circular sound insulation board 33, the sound insulation board 33 is a honeycomb board, the inner side of the sound insulation board 33 is pasted with a sound-absorbing cotton layer 34, and the other side of the sound-absorbing cotton layer 34 is connected to the outer cover 31. internal fixed connection

[0035] Through the above scheme of the present invention, the beneficial effect is that the wind cover 19 is provided with a sound insulation mechanism, which can eliminate noise to a certain extent on the working noise generated during work, and can also eliminate noise from the motor 16 generated by the motor 16. The noise ge...

Abstract

The invention discloses a diesel engine with a protection mechanism for agricultural machinery, which includes a support plate, an auxiliary support plate is arranged on the top of the support plate, a diesel engine is placed on the top of the auxiliary support plate, the support plate and the A shock-absorbing mechanism is arranged between the auxiliary supporting plates, and the shock-absorbing mechanism includes a spring, the top end of the spring is fixedly provided with an upper threaded plate, the bottom end of the spring is fixedly provided with a lower threaded plate, and the upper threaded plate and the The lower threaded plate is respectively fixed on the support plate and the auxiliary support plate by screws. Beneficial effects: the sound can be impacted with the spring sheet multiple times, and the spring sheet vibrates for effective noise reduction. The spring sheet is connected to the secondary honeycomb panel for subsequent noise reduction, because the water cavity is filled with water, which can prevent the transmission of sound. Therefore the water that is set carries out the final sound-absorbing part, plays four-fold sound-absorbing, reduces the transmission of sound greatly, avoids noise pollution, and the device of this setting is suitable for the diesel engine that small and medium-sized agricultural machinery is used.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a diesel engine with a protective mechanism for agricultural machinery. Background technique [0002] The advantages of diesel engines, such as large load capacity, low specific fuel consumption, and high thermal efficiency, have been continuously promoted. The agricultural machinery powered by diesel engines is huge in my country. With the continuous advancement of agricultural mechanization, the total power of agricultural machinery in the country has reached 972 million kilowatts, and the proportion of diesel engine power has reached 77.35%. When the existing diesel engine is in use, it cannot be well protected against noise pollution and heat radiation pollution, thus greatly shortening the service life of the diesel engine. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The object ...
