Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1-4, an embodiment of the present invention provides a cotton plucking assembly, which can be assembled on a rotating shaft or in a cage-type frame to form an assembled cotton plucking beater. Because the cotton grabbing components can be arranged in parallel according to the requirements, a plurality of cotton grabbing components can be flexibly installed according to the actual opening requirements of the cotton grabbing machine, so that the opening effect can be controlled.

The cotton grasping assembly includes a ring 100 and a plurality of blades 200 mounted on the outer edge of the ring 100.

The ring body 100 includes an outer ring body 101 and an inner ring body 102 which are coaxial and both of which are annular structures, and the two are connected and fixed by struts 103 symmetrically arranged at two sides to form a wheel shape, so that an interlayer space exists between the struts 103.

The outer edge of the inner ring 102 is recessed with an annular groove 102a, and a drive ring 104 capable of relative rotation is embedded inside the annular groove. Specifically, two side surfaces of the annular groove 102a are symmetrically provided with annular grooves 102b, the driving ring 104 is of an annular structure and hoops in the annular groove 102a, two side surfaces of the driving ring 104 are provided with annular protrusions 104b matched with the annular grooves 102b, and the annular protrusions 104b are embedded in the annular grooves 102b and can rotate relatively.

The blades 200 are hinged in the outer ring body 101 and can rotate about a hinge point. The two ends of the blade 200 are respectively a cutter head 201 and a cutter tail 202, the driving ring 104 is connected with the cutter tail 202 through a connecting rod 105, and the outer ring body 101 is provided with a corresponding through opening 101 a. Specifically, a plurality of receiving grooves 101b corresponding to the respective blades 200 are circumferentially distributed on the outer ring body 101, and the respective blades 200 are hinged in the corresponding receiving grooves 101b and can rotate the cutting head 201 thereof outward out of the receiving groove 101b by rotation. The driving ring 104 has a hinge base 104a corresponding to each blade 200 on the outer periphery thereof, and the link 105 has one end hinged to the cutter tail 202 and the other end hinged to the hinge base 104 a. Therefore, when the drive ring 104 is rotated, the corresponding blades 200 can be pulled by the links 105 to be synchronously rotated out of the receiving grooves 101b, and the blades are in the "opened" state.

Further, the edge of the upper port of the receiving groove 101b is provided with a limit block 101d, which corresponds to the back of the blade 200 and can limit the outward rotation range of the blade 200. When the blade 200 is pulled by the connecting rod 105 and rotates outwards to a fully opened state, the back of the blade 200 can abut against the edge of the limiting block 101d, and the limiting block 101d limits the blade to rotate continuously. Meanwhile, when the opening operation is performed, the blade 200 can be stably ensured.

Further, the root of the bit 201 is connected to the bottom of the receiving groove 101b by a tension member 101c, where the tension member 101c is an extension spring for returning and receiving the blade 200.

In order to maintain the blade 200 in a stable state after rotating to a certain angle and prevent self-reset rebound, the invention has the following technical scheme:

the bottom of the annular groove 102a is provided with ratchet teeth 102c (peripheral convex teeth of the ratchet wheel), the driving ring 104 is provided with a radially through allowable space 104c, the inside of the driving ring is hinged with a pawl 104d, the pawl 104d is matched with the ratchet teeth 102c, the driving ring 104 can only move towards one direction under the constraint of the ratchet teeth 102c, and the knife tail 202 can be pulled by the connecting rod 105 in the moving direction, so that the knife head 201 can rotate outwards out of the accommodating groove 101 b. Preferably, an elastic member 104e is further fixed in the allowable space 104c, the elastic member 104e may be an elastic sheet or a compression spring, and the elastic member 104e presses the back of the pawl 104d, so as to ensure the close fit between the pawl 104d and the ratchet 102c and prevent accidental falling.

In order to make the driving ring 104 reversely rotate after being restrained by the ratchet 102c and to make the blades 200 be accommodated in the corresponding accommodating grooves 101b again, the invention has the following technical proposal:

the pawl 104d is integrally divided by a hinge point into a head portion 104d-1 and a tail portion 104d-2 on both sides, wherein the head portion 104d-1 is engaged with the ratchet teeth 102c, and the tail portion 104d-2 is protruded out of the allowance space 104 c. When the extended tail 104d-2 is manually depressed, the pawl 104d will rotate and disengage the head 104d-1 from the ratchet teeth 102c, and the restraint is removed. Subsequently, the tension member 101c pulls the blade 200 to rotate reversely, the blade 200 transmits a pulling force through the link 105 and pulls the drive ring 104 to the initial state, and the reset is completed. Finally, the tail 104d-2 is released and the ratchet teeth 102c again restrain the pawl 104d so that the blade 200 remains "stowed".

The cotton grabbing component can be fixed in the following two ways:

key grooves are formed in the inner side surfaces of the inner ring body 102, are sleeved on the rotating shaft, and are matched with the key grooves to fix the cotton grabbing component on the rotating shaft;

and second, fixing grooves 101e distributed in the circumferential direction are formed in the outer edge of the outer ring body 101 and are installed in the cage-shaped beater frame, and the longitudinal beam of each cage framework penetrates through the fixing grooves 101e to achieve constraint and matching.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
