Abstract
Disclosed is a seed fertilizer box lid locking device belonging to farm machinery; the device comprises a box lid, a hinge and a box body, the left end and the right end of a pneumatic spring assembly are respectively in hinged connection with the left side part of the box lid and the right side part of the box body, and the height position of a hinged point positioned on the box lid is lower than the height position of a hinged point positioned on the box body; and the device is simple in structure and low in manufacturing cost, the locking of the box lid at the opening and closing position on the box body is firm and reliable, the box body has good tightness when in operation, and the use safety is high.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the seed manure case on the seeding and fertilizing facility.
Background technology
At present, be fitted in the seed manure case on the seeding and fertilizing facility of various structures, after its case lid and casing are integral by the hinge hinge, there is not any position and lock mechanism between case lid and the casing again, case lid can swing up and down around hinge one side on casing, and during operation, case lid is located not firm on casing, not only the casing seal is poor, and has reduced facility service life.Simultaneously, carry out seed manure and add when operating in the casing opening case lid, the case lid of latch-up-free control often takes place to rotate voluntarily closes situation, very easily injures operating personnel by a crashing object, causes personal injury, and safety in utilization is poor.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides a kind of seed manure case case lid locking device, reaches airtight performance when improving the seed manure casing working, prolongs facility service life, guarantees the purpose that handling safety is reliable, avoid personal injury.
Basic design of the present utility model is, seed manure case case lid locking device comprises case lid, hinge and casing, the left and right two ends of pneumatic spring assembly are hinged with case lid left side and casing right side respectively, and the hinge point height and position that is positioned on the case lid left side is lower than the hinge point height and position that is positioned on the casing right side.
The utility model is simple in structure, cheap for manufacturing cost, when case lid when in the closed position on the casing or case lid are shown in an open position on casing, can be effectively reliably with case lid locking position on casing, casing airtight performance when having guaranteed operation, avoided case lid falling situation voluntarily to take place simultaneously, safety in utilization is good.
Description of drawings
Accompanying drawing is a seed manure case case lid locking device overall arrangement structural representation.
Piece number explanation among the figure:
1, case lid, 2, pneumatic spring assembly, 3, hinge, 4, casing.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in detail.Seed manure case case lid locking device comprises case lid 1, hinge 3 and casing 4, the left and right two ends of pneumatic spring assembly 2 are hinged with case lid 1 left side and casing 4 right sides respectively, and the hinge point height and position that is positioned on case lid 1 left side is lower than the hinge point height and position that is positioned on casing 4 right sides.
When case lid 1 is closed with casing 4, the thrust of pneumatic spring assembly 2 is pushed the hinge point place of case lid 1 and casing 4 to through left and right two ends, because the hinge point height and position on the case lid 1 is lower than the hinge point height and position of casing 4, downward component of thrust formation of pneumatic spring assembly 2 is pressed against on the left side of case lid 1, case lid 1 is covered securely overlay on the casing 4, do not beat.Upwards lift case lid 1 with hand and make it wrap page or leaf during 3 rotating opening on casing 4, the thrust of pneumatic spring assembly 2 makes case lid 1 in casing 4 lockings, can not fall after rise naturally.
