Description
Technical field
The present invention relates to a kind of overload-release clutches for potato picker.
Background technique
Potato planting is extensive, full of nutrition, is known as " underground apple ", " diet upstart " and " ten big hot topic nutrient healths
The title of food " is the 4th generalized grain crop of the world after corn, wheat and rice.China is world's potato planting area
One of maximum country and the country push potato staple food grain, are processed into the staple foods such as steamed bun, noodles, rice flour, cultivated area with it
Gradually expand.But the horizontal lower poor of international competitiveness of potatoes production mechanization much can not meet market and need
It asks.
In view of the above problems, various types of potato pickers come into being, and the clutch knot in potato picker
Supreme guarantee of the structure as safety, is also increasingly valued by people, traditional friction coupling cost is high, and can not grow
Phase runs in muddy water, and based on the clutch structure of Purely mechanical with low cost, stability is good, gets over convenient for Operation and Maintenance
To be more taken seriously.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, propose a kind of for potato picker
Overload-release clutch.
A kind of overload-release clutch for potato picker, including drive shaft, driven shaft and connection sleeve；The drive
Moving axis is connected to the motor, and the driven shaft is connected with the digging part of potato picker, and annular limit is also connected on driven shaft
Position block；The connection sleeve is socketed on the outer wall of driven shaft by connecting key, and the head for connecting sleeve is and drive shaft tail
The claw-type structure that portion matches；The upper end of driven shaft is additionally provided with link mechanism, and the link mechanism includes in the connection of falling Y-shaped
Left connecting rod, right connecting rod and push rod；The tail portion of the push rod is connected with cylinder, and the cylinder is fixed on body frame, on push rod also
It is cased with spacing collar and reset spring, the side of the spacing collar is connected with body frame, and one end of the reset spring is supported
The circlip connect on the upper end of spacing collar, the other end and push rod is connected；The head of the left connecting rod is connected with left slider, described
Left slider can connection sleeve on the right side of first annular sliding slot in slide；The head of the right connecting rod is connected with right sliding block, institute
The right sliding block stated can slide in the second annular groove on the left of ring limit block.
Preferably, even there are three the triangle fixture block being circumferentially equally spaced, the claw types for the tail portion of the drive shaft
The triangle card slot that structure is circumferentially equally spaced by three forms.
Preferably, the first annular sliding slot is equal with the diameter of the second annular groove.
Preferably, the ring limit block is connected by welding with driven shaft.
Preferably, the connecting key is kidney-shaped connecting key.
The utility model has the advantages that
By the state of cylinder controls connecting rod mechanism, when cylinder gas supply, push rod moves downward and drives connecting rod to two sides
Rotation, to control the clutch state of connection sleeve and drive shaft, cylinder once suspends gas supply, under the action of reset spring,
Push rod moves upwards, and connection sleeve is separated with drive shaft, at this point, drive shaft can not transfer its energy to adopting for potato picker
Part is dug, can be using the air supply valve of cylinder as safety switch for a feature, when use, once finds problematic production
It is raw, safety switch is pressed immediately, can effectively ensure the life security of people and animals around user and potato picker.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
As shown in Figure 1-3, a kind of overload-release clutch for potato picker, including drive shaft 3, driven shaft 2 and company
Female connector cylinder 4；The drive shaft 3 is connected to the motor, and the driven shaft 2 is connected with the digging part of potato picker, from
Ring limit block is also connected on moving axis 2；The ring limit block is connected by welding with driven shaft 2.
The connection sleeve 4 is socketed on the outer wall of driven shaft 2 by kidney-shaped connecting key 15, connects the head of sleeve 4
For the claw-type structure to match with 3 tail portion of drive shaft；Even there are three the triangles being circumferentially equally spaced for the tail portion of the drive shaft 3
Fixture block, the triangle card slot that the claw-type structure is circumferentially equally spaced by three form.
The upper end of driven shaft 2 is additionally provided with link mechanism, and the link mechanism includes the left connecting rod in the connection of falling Y-shaped
14, right connecting rod and push rod 13；The tail portion of the push rod 13 is connected with cylinder 11, and the cylinder is fixed on body frame 1, on push rod
It is also cased with spacing collar 12 and reset spring, the side of the spacing collar is connected with body frame, and the one of the reset spring
End is connected to the upper end of spacing collar 12, and the other end is connected with the circlip on push rod 13；The head of the left connecting rod 14 and left cunning
Block is connected, and the left slider can slide in the first annular sliding slot on 4 right side of connection sleeve；The head and the right side of the right connecting rod
