Abstract
The utility model relates to an engine structure, in particular to an engine structure with a muffler shield, which mainly comprises a cylinder cover, a crankcase cover, an oil tank, a muffler, an air filter and a wind guide cover which are arranged on an engine body. The cylinder cover is provided with an oil sprayer. The cylinder cover is connected with the air filter by an air inlet pipe. The engine body is connected with the muffler by an exhaust pipe. The oil tank, the muffler and the air filter are arranged around a cylinder head. The engine body is fixed with the muffler shield by a fastening bolt and a clamp nut. The muffler shield is laminated to the curve of the exhaust pipe and the periphery of the muffler shield is bent downwards. The engine structure of the utility model can convey the pressurizing cooling airflow from a fan to the muffler to cool the cylinder head, the exhaust pipe and the muffler so as to promote cooling performance of an engine and can also greatly reduce noise generated by the exhaust pipe so as to reduce noise of the engine and better improve sound insulation property.
Description
Technical field
The utility model relates to a kind of engine structure, especially a kind of engine structure with silencer shield.
Background technique
In prior art, the known motor of the public is to be equipped with parts such as silencing apparatus, fuel tank, air-strainer on cylinder head.During such engine operation, be with cooling blast by be arranged on motor wherein the fan of a side be delivered to the opposite side of motor, to carry out cooling to motor.This kind structure engine only possesses the structure that the guiding cooling blast is arranged, do not consider the cooling of silencing apparatus and muffler tail pipe, such situation causes silencing apparatus and muffler tail pipe surface temperature higher, the operator is scalded when running into outlet pipe because of carelessness easily, along with the raising to the engine health performance requirement, it is imperative to reduce silencing apparatus and muffler tail pipe surface temperature.In addition, even to silencing apparatus the surface temperature that outer cover improves silencing apparatus is installed in the past, but because the whole silencing apparatus of outer cover has caused the cover structure complexity, installs loaded down with trivial detailsly, the while also reckons without the cooling of outlet pipe, and operability is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and supercharging cooling blast from fan can be delivered to silencing apparatus, thereby cooling air cylinder head, outlet pipe and silencing apparatus promotes the cooling performance of motor with this; Also can reduce simultaneously the noise that produces by outlet pipe greatly, thereby reduce the noise of motor, better improve the engine structure with silencer shield of sound insulation value.
The technological scheme that provides according to the utility model, described engine structure with silencer shield is included in the cylinder head of installing on the body, crankcase cover, fuel tank, silencing apparatus, air-strainer and wind scooper, cylinder head is provided with oil sprayer, link to each other with suction tude between cylinder head and the air-strainer, link to each other by outlet pipe between cylinder head and the silencing apparatus, fuel tank, silencing apparatus and air-strainer be arranged on cylinder head around, feature is: be fixed with silencer shield by clamping bolt and tightening nut on the described cylinder head, the curve of described silencer shield applying outlet pipe, bending downwards all around.
The thickness of described silencer shield is 1～2mm.Have the gap between described silencer shield and the silencing apparatus, and described gap width is 3～5mm.
Be provided with asbestos washer between silencer shield and tightening nut, described asbestos washer is socketed on the clamping bolt.
Compared with the prior art the utility model has the following advantages:
1, the utility model can be installed in silencer shield on the silencing apparatus simply, and motor is when needing repairing, as long as individually silencer shield is unloaded, can be easily the part of the required maintenance of motor be unloaded, and promotes maintenance.
2, above-mentioned guard shield covers cylinder head exhaust outlet and muffler tail pipe, can prevent the diffusion of the noise that produced by cylinder head and muffler tail pipe greatly, thereby reduces the noise of motor, better improves the sound insulation value of motor.
3, because guard shield has been covered outlet pipe, cause unnecessary damage outside thereby avoided outlet pipe to expose on the one hand, and prevented that the operator from touching and outlet pipe because of carelessness, thereby promoted the Safety performance of motor.
4, because above-mentioned silencer shield is fixed on the body by clamping bolt, so just do not need cost has been saved in other part processing change.
5, guard shield can be used as flow guide device, can guide the supercharging cooling blast from fan, and cool off the space of forming by cylinder head and this device and be delivered to the silencing apparatus side again, thus more effective cooled exhaust pipe and silencing apparatus.
7, owing to, thus, then need not so just can easily the migration of this motor be transported with guard shield from engine removal at above-mentioned guard shield applying outlet pipe curve.
8, because at above-mentioned guard shield applying outlet pipe curve, the outward appearance of motor can not be damaged, and has promoted the outward appearance of motor simultaneously.
9, the space between above-mentioned cylinder head and the silencer shield forms guide portion, thus, can guide the supercharging cooling blast that comes from fan by guide portion, and can make its shunting, like this, just can cooled exhaust pipe, also can cool off silencing apparatus, and can form the cooling blast guide portion simply with original component.Like this, then need not save cost at the additional special part of engine main body.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly is made of parts such as cylinder head 1, body 2, crankcase cover 3, fuel tank 4, silencing apparatus 5, air-strainer 6, wind scooper 7, clamping bolt 8, asbestos washer 9, silencer shield 10, oil sprayer 11, suction tude 12, tightening nut 13, outlet pipe 14 and gaps 15.
This has the engine structure of silencer shield, be included in the cylinder head 1 of installing on the body 2, crankcase cover 3, fuel tank 4, silencing apparatus 5, air-strainer 6 and wind scooper 7, cylinder head 1 is provided with oil sprayer 11, link to each other with suction tude 12 between cylinder head 1 and the air-strainer 6, link to each other by outlet pipe 14 between body 2 and the silencing apparatus 5, fuel tank 4, silencing apparatus 5 and air-strainer 6 be arranged on cylinder head around, on body 2, be fixed with silencer shield 10 by clamping bolt 8 and tightening nut 13, the curve of described silencer shield 10 applying outlet pipes 8, bending downwards all around.
The thickness of described silencer shield 10 is 1～2mm.Have gap 15 between described silencer shield 10 and the silencing apparatus 5, and described gap 15 width are 3～5mm.
