Abstract
The invention relates to a mounting structure of a muffler outer hood of a snow remover, which comprises an inner hood, an outer hood, an air filter, a cylinder end and a muffler. The mounting structure is characterized in that the inner hood and a bracket at the top part of the muffler are connected by a bolt; the outer hood is arranged at the outside of the inner hood; one end of the outer hood is welded with one end of the outer hood of the muffler; the other end of the outer hood is connected with the shell of the air filter by a bolt; the cylinder end is fixed in the shell of the air filter, a protective hood and the inner hood by bolts. The adopted technical proposal leads the outer hood and the inner hood not to be contacted, avoids the heat of an engine from being directly transferred to the outer hood of the muffler and has the advantage of safe use.
Description
Technical field
The present invention relates to a kind of silencer, particularly a kind of mounting structure of muffler outer hood of snowplow.
Background technique
Snowplow is widely used in frequent snowy cold area because of its accumulated snow that can clean the road surface fast.And drive what sweep away snow the work of mechanical shovel snow is motor.Crossing and the device of attenuate acoustic noise and silencing apparatus is a kind of air communication that allows, is one of important spare part of snowplow.The quality of silencing apparatus performance not only influences the size of snowplow noise, and performances such as the power of motor, oil consumption, moment of torsion are all had considerable influence.
Traditional muffler outer hood and inner cover are in the same place by bolt with silencing apparatus, because the heat that produces during engine operation, make the silencing apparatus inner cover become high-temperature component, the silencing apparatus inner cover is passed to big outer cover to high temperature by four double-screw bolts, expose in the muffler outer hood temperature of outer surface higherly, be easy to cause security incident.In addition, muffler outer hood and inner cover and silencing apparatus need be at silencing apparatus at last welding screws, because the area of contact of silencing apparatus and double-screw bolt is little by bolt, silencing apparatus and stud welding place also can influence its both join strength because of welding causes that stress is concentrated and material changes; Also have, because of the double-screw bolt area of contact of inner cover and silencing apparatus is too little, the welding lifting surface area is also little, adds the vibrations of motor, makes silencing apparatus easily break at the welding screw place, causes security incident easily.
Summary of the invention
The present invention is exactly the deficiency at existing silencing apparatus technology, and a kind of mounting structure of muffler outer hood of snowplow is provided, and it makes outer cover not contact with inner cover, avoids the heat of silencing apparatus is directly delivered to muffler outer hood, and advantage safe in utilization is arranged.
The object of the present invention is achieved like this: the mounting structure of the muffler outer hood of snowplow, comprise inner cover, outer cover, empty filter, cylinder head and silencing apparatus, described inner cover is connected by bolt with the support at silencing apparatus top, outer cover is positioned at the outside of inner cover, one end of outer cover and the welding of an end of silencer shield are logical, the other end of outer cover is connected with empty filter housing bolt, and cylinder head is by being bolted in sky filter housing, guard shield and the outer cover.
The both sides of described outer cover are provided with rhone.
The top of described outer cover is provided with radiation hole.
Described support runs through the top of silencing apparatus, and the support two ends are welded on the both sides of silencing apparatus.
Because adopt technical solution of the present invention, outer cover no longer contacts with inner cover, the heat that has produced in the time of can having avoided inner cover with engine operation is directly passed to outer cover, greatly reduces the temperature of outer cover, has eliminated consequent potential safety hazard.In addition, welding support on silencing apparatus, inner cover is fixed by bolt and silencing apparatus, because inner cover and support area of contact are big more than the area of contact of inner cover and double-screw bolt, increased the area of contact of inner cover and silencing apparatus, it is more reliable that inner cover is connected with support, and its shock resistance is good.Because support and silencing apparatus bonding area are big more than the area of double-screw bolt and body, the heat energy that produces when making silencing apparatus work is uniformly dispersed along with welding point uniform, it is little that silencing apparatus and support are influenced by welding, silencing apparatus and support cause that because of welding the influence that stress is concentrated and material changes is little, and the join strength of silencing apparatus and support is good.At the some radiation holes of outer cover outer installment, help heat radiation.Muffler outer hood is provided with rhone, and the water after the ice dissolution is flowed down along rhone, and the working environment of motor can keep low operating temperature, has further increased factor safe in utilization.
The present invention makes that by changing the linkage structure of eliminating the noise with outer cover heat can all not be dispersed on the outer cover when engine running, can guarantee that the silencing apparatus running is more normal, it is safer to use.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the scheme of installation of outer cover and inner cover;
Fig. 3 is the structural representation of outer cover.
Among the figure: 1 is guard shield, and 2 is outer cover, and 3 is empty filter housing, and 4 is cylinder head, and 5 is rhone, and 6 is radiation hole, and 7 is outlet pipe, and 8 is silencing apparatus, and 9 is support, and 10 is inner cover, and 11 is bolt.
Specific embodiment
Referring to Fig. 1-Fig. 3, at the top of silencing apparatus 8 two supports 9 are set, described support runs through the top of silencing apparatus, and the support two ends are welded on the both sides of silencing apparatus, are used for inner cover 10 is connected by bolt 11 with the support at silencing apparatus top.Outer cover 2 is positioned at the outside of inner cover, and the both sides of described outer cover are provided with rhone 5, the heat that snowplow was produced in when work, will attached on the snowplow thaw ice and snow and the water that produces flows out snowplow along rhone.The top of outer cover is provided with radiation hole 6, and the heat that produces when snowplow is worked in time distributes.One end of outer cover and the welding of an end of silencer shield 1, the other end of outer cover is connected with empty filter housing 3 bolts, and cylinder head 5 is by being bolted in sky filter housing, guard shield and the outer cover, and outlet pipe is fixed by bolts to the top of silencing apparatus.Adopt said structure, outer cover is not contacted with inner cover, the heat that has produced in the time of can having avoided inner cover with engine operation is directly passed to outer cover, greatly reduces the temperature of outer cover.
