Description
Technical field
The utility model is related to a kind of sprayer engine cylinder covers on sprayer engine.
Background technology
Power driven sprayer in use due to small easy to carry, the design of engine be also it is less than normal,
Due to small, the heat that engine generates is without reduction, and sprayer engine cylinder cover is mounted on engine cylinder body
Above, from top seal cylinder and combustion chamber is constituted, it is often in contact with high-temperature high-pressure fuel gas, therefore it is negative to bear prodigious heat
Lotus and mechanical load, therefore the engine cylinder cover of sprayer is the key that heat dissipation, and traditional sprayer engine cylinder cover is dissipating
Design not in place in heat, heat can cause to burn abnormal after rising, early combustion and detonation occur, also part overheat leads to material
Mechanical characteristic reduces and generates serious thermal stress, leads to deformation and crackle, destroys normal movement clearance between each moving parts,
Frictional resistance is caused to increase, ablation, card can occur when serious for abrasion aggravation, the especially movement between piston ring and cylinder wall
It is stagnant, make to stall or occur pull-cylinder phenomena, temperature is excessively high, can also make deterioration of lubricant, scaling loss and coking and lose profit
Slip energy destroys lubricating oil film, the friction and abrasion aggravation of part.These all by cause engine dynamic property and economy,
Reliability, durability deteriorate comprehensively.
Invention content
To solve the above problems, the purpose of this utility model is to provide a kind of good heat dissipation effect and structures reliably to spray
Day with fog engine cylinder cover.
To achieve the above object, the utility model provides following technical solution：A kind of sprayer engine cylinder cover, including
Cover board, the cover board are equipped with several first cooling fins being arranged in order along cover board length direction, several described first
Cooling fin is placed in radiation character arrangement, and the length of the first cooling fin and the width of the cover board match, in the cover board
Between position cross the mounting groove of square shape, the first cooling fin positioned at installation groove location is connected on the outer wall of the mounting groove,
Symmetrical mounting hole is set on the slot bottom of the mounting groove, the second heat dissipation of interval location setting between the mounting hole
Piece, second cooling fin is identical as the placement direction of the first cooling fin, the thickness of second cooling fin bottom to top
Degree is convexly equipped with pillar in the middle part of the mounting groove, injection hole is arranged on the pillar with highly successively decreasing.
It is equipped with locating convex block corresponding with the mounting groove in the bottom of the cover board, which is square, side
The edge of projection arc on the both sides side of shape is additionally provided with corresponding with the injection hole horn-like on the locating convex block
Groove.
Interval location between first cooling fin is additionally provided with connecting plate.
Cover board, first cooling fin and second cooling fin is integrally formed for aluminium die casting.
This structure of the utility model, the first cooling fin can be effectively increased heat dissipation on the cover board in radiation shape arrangement
Area, and be effectively increased the interval of adjacent first cooling fin, increase heat-dissipating space, the centre position of cover board crosses square shape
Mounting groove can facilitate the installation of cover board, while the second cooling fin is arranged in interval location between mounting hole, further increases
The utilization in space and heat dissipation effect, and connecting plate is set between the first cooling fin and improves structural reliability, it is just real in this way
Good heat dissipation effect and the reliable technique effect of structure are showed.
The utility model is further described with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the lower parallax stereogram of specific embodiment of the present invention；
Fig. 2 is the upper parallax stereogram of specific embodiment of the present invention.
Specific implementation mode
The utility model is specifically described below by embodiment and Structure Figure.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of sprayer engine cylinder cover, including cover board 1, on cover board 1
Equipped with several first cooling fins 2 being arranged in order along 1 length direction of cover board, several first cooling fins 2 are in radiation character row
Row are placed, and the length and the width of cover board 1 of the first cooling fin 2 match, and the centre position of cover board 1 crosses the mounting groove of square shape
3, the first cooling fin 2 positioned at 3 position of mounting groove is connected on the outer wall of mounting groove 3, is arranged on the slot bottom of mounting groove 3 mutual
The second cooling fin 4, the second cooling fin 4 and the first cooling fin 2 is arranged in symmetrical mounting hole 31, the interval location between mounting hole 31
Placement direction it is identical, the thickness of 4 bottom of the second cooling fin to top is convexly equipped with convex with highly successively decreasing at the middle part of mounting groove 3
Injection hole 51 is arranged in column 5 on the pillar 5.
It is equipped with locating convex block 6 corresponding with mounting groove 3 in the bottom of cover board 1, which is square, rectangular
The edge 61 of projection arc on the side of both sides, is additionally provided with horn-like groove corresponding with injection hole 51 on locating convex block 6
62.Such design can make cover board 1 that can make lubricating oil splash with groove 62 relatively reliable during Engine Matching, horn-like
It is more easy to be detached from injection hole 51 in the process, plays the role of certain leakproof.
Interval location between the first cooling fin 2 is additionally provided with connecting plate 7.The structure of the first cooling fin 2 can be improved in this way
Rugged performance, and then improve service life.
Cover board 1, the first cooling fin 2 and the second cooling fin 4 are integrally formed for aluminium die casting.Integrated molding can effectively improve entirety
Structural reliability and suitable for produce in enormous quantities reduce manufacturing cost.
This structure of the utility model, the first cooling fin 2 be arranged in radiation shape on cover board 1 can be effectively increased it is scattered
