Description
Technical field
The utility model relates to harvester more particularly to double helix harvester blades.
Background technique
Harvester is a kind of machinery of integration harvesting crops, disposable to complete harvesting, threshing, and grain is focused on
Repository.Harvester gathers in the straw cutting of crops by harvester blade, before harvester blade is mounted on harvester
End.In the prior art, harvester blade is rigidly connected with harvester mostly, and is single strip or sheet, and when work gathers in
Due to toughness deficiency, blade head easily snaps off machine knife blade after encountering the hard object such as stone.
Utility model content
The utility model is in view of the above problems, provide a kind of structure simple, easy disassembly, double spiral shells improved service life
Revolve harvester blade.
The technical solution of the utility model is: further include connection structure including cutter hub, the connection structure include sleeve,
Connecting tube and a pair of symmetrically arranged spring, the sleeve are located at the side of cutter hub, are equipped with internal screw thread, the company in the sleeve
Adapter tube includes tube body, and one end of the tube body is located in sleeve, the other end is equipped with connecting hole, and the centre of the tube body is helically
Shape, the tube body and sleeve are connected through a screw thread；
The spring is connected between cutter hub and tube body.
The spring is located at the inside of tube body.
The sleeve weld is connected on cutter hub.
The cutter hub is equipped with threaded hole, and the surface of the sleeve is equipped with external screw thread, and the sleeve is connected through a screw thread knife
Body.
At work, by the way that sleeve is arranged on cutter hub, connecting tube is threadedly attached in sleeve the utility model, side
Just dismounting connection, convenient for being convenient for changing in cutter hub damage；Connecting hole is set on tube body, is connected convenient for being installed with harvester.Pipe
Helical form, settable double helix are set among body, so that connecting tube under the premise of proof strength, has toughness and memory function
Energy.Meanwhile a pair of of spring is set, play the role of auxiliary connection, so that tube body connects reliably with cutter hub.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
1 is cutter hub in figure, and 2 be sleeve, and 3 be spring, and 4 be tube body, and 5 be connecting hole.
Specific embodiment
The utility model further includes connection structure as shown in Figure 1, including cutter hub 1, and the connection structure includes sleeve 2, connects
Adapter tube and a pair of symmetrically arranged spring 3, the sleeve are located at the side of cutter hub, are equipped with internal screw thread, the company in the sleeve
Adapter tube includes tube body 4, and one end of the tube body is located in sleeve, the other end is equipped with connecting hole 5, and the centre of the tube body is helically
Shape, the tube body and sleeve are connected through a screw thread；
The spring is connected between cutter hub and tube body.
At work, by the way that sleeve is arranged on cutter hub, connecting tube is threadedly attached in sleeve the utility model, side
Just dismounting connection, convenient for being convenient for changing in cutter hub damage；Connecting hole is set on tube body, is connected convenient for being installed with harvester.Pipe
Helical form, settable double helix are set among body, so that connecting tube under the premise of proof strength, has toughness and memory function
Energy.Meanwhile a pair of of spring is set, play the role of auxiliary connection, so that tube body connects reliably with cutter hub.
The spring 3 is located at the inside (i.e. the inside of intermediate conveyor screw shape) of tube body.
Hook can be respectively set on cutter hub and tube body, spring is facilitated to connect, installation is reliable.
The sleeve 2 is welded to connect on cutter hub.It is welded to connect, facilitates processing.
The cutter hub is equipped with threaded hole, and the surface of the sleeve is equipped with external screw thread, and the sleeve is connected through a screw thread knife
Body.
Facilitate sleeve dismounting connection, operation is reliable.
