Description
Technical field
The disclosure relates generally to agricultural operation equipment technical field and in particular to rice transplanter, more particularly, to hood.
Background technology
China, as traditional agriculture big country, has abundant land resource, is required for every year carrying out substantial amounts of farming species
Plant.With social technology development, proportion of crop planting technology is also developed rapidly, and proportion of crop planting equipment has also obtained soon
Speed updates.As rice transplanter, it is by one of rice seedling implantation rice field special agricultural machinery, considerably improves rice transplanting effect
Rate, there is wide market development prospect at home.Rice transplanter can be divided into walk-behind type paddy-field work machine and riding type to insert by mode of operation
Seedling machine.Common seedling transplanter and high-speed transplanter can be divided into by rice transplanting speed.
High-speed transplanter generally comprises seedlings sending mechanism, planting mechanism, walking mechanism, transplanting mechanism etc., simultaneously high speed rice transplanting
Machine needs electromotor to provide power to make its work.Because the use season of high-speed transplanter is typically all in time busy farming season summer, its
In adverse circumstances often at high-temperature high humidity during operation, and long-term high load capacity work, fuselage is caused with larger wound
Evil, because electromotor is in order to overcome running resistance, needs to produce big power, allowing for electromotor needs to carry out severe use, but
Meanwhile, also will bring a side effect it is simply that engine temperature can be lifted very high, and and then lead to engine motor oil can lose
Effect, so that piston and cylinder sleeve will be able to be killed because crossing thermal expansion, is gently then stopped working, heavy then engine damage.And what electromotor carried
Cooling mechanism sometimes can not meet above-mentioned cooling and require.If additionally increasing cooling mechanism, increasing further and being manufactured into
This, and the load to fuselage also can increase therewith.
Content of the invention
In view of drawbacks described above of the prior art or deficiency are it is desirable to provide a kind of Air Temperature that can be lowered into electromotor
The hood of degree.
The present invention provides a kind of hood, and including main cover plate, main cover plate includes medial surface and lateral surface, and main cover plate is provided with and passes through
Wear the air intake passage of medial surface and lateral surface, in air intake passage, be provided with cooling zone, perpendicular to the area of section of axis in cooling zone
Air-admitting surface less than air intake passage.
The hood that the present invention provides, can be used for setting on the engine, and medial surface, near the inlet scoop of electromotor, passes through
It is less than the air-admitting surface of air intake passage using the area of section perpendicular to axis in cooling zone so that the external world through cooling zone
The temperature of surrounding air can reduce 5-10 degree Celsius, so make extraneous high temperature air before entering electromotor inlet scoop
Through having carried out cooling process.The hood that the present invention provides by the change of air inlet structure it is achieved that bearing not increasing electromotor
In the case of load and extra heat dissipation equipment, Physical temperature-lowering is carried out to electromotor, ensured that electromotor can be grown in farm work
Time exports firm power.
