Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
The invention is further described below with reference to examples.
Examples:
the swing ring box is a structure for driving the swing ring shaft to swing reciprocally through the output shaft, and as the output shaft is provided with an eccentric cylinder, the swing ring fork on the swing ring shaft is hinged on the cylinder, and when the output shaft rotates, the swing ring shaft can swing reciprocally, so that the swing arm forms an arc-shaped reciprocating motion, and the cutter can work.
However, after the output shaft stops rotating, the swinging ring fork always rotates synchronously with the output shaft, and the swinging arm is probably not completely in a natural sagging state, and can swing continuously under the action of gravity, and potential energy generated by the swinging can cause a certain burden on the swinging ring shaft, and the swinging ring shaft is easy to damage after long-term use.
Therefore, this scheme provides a low noise harvester pendulum ring case and solves such problem, and with reference to fig. 1-7 (b), specifically, this scheme mainly includes box 1, pendulum ring 2 and resistance cover 3 three parts, and the middle part of box 1 is equipped with a drive shaft 11, and in this scheme, drive shaft 11 accessible bevel gear cooperates with the output shaft of motor, also can directly drive through driving motor, is known technique, and this case does not have too much description.
The swinging ring 2 comprises a swinging ring shaft 21 and a swinging arm 22, one end of the swinging arm 22 extends out of one side of the box body 1, in practice, the swinging arm 22 is fixed with the cutting knife, the cutting knife is enabled to work through the swinging of the swinging arm 22, and the specific fixing mode between the swinging arm 22 and the cutting knife is a known technology and is not shown in the present case.
The swinging ring shaft 21 is vertically arranged with the driving shaft 11 and is matched with the driving shaft 11 through the swinging ring fork 23, a cylinder block which is obliquely arranged is arranged on the driving shaft 11, the swinging ring fork 23 is hinged on the cylinder block, one side of the swinging ring fork 23 is connected with the swinging ring shaft 21, thus when the driving shaft 11 rotates, the swinging ring fork 23 regularly and reciprocally rotates on the cylinder block, and the formed swinging ring structure drives the swinging arm 22 to swing in an arc shape.
In order to avoid free rotation of the swing arm 22, in this case, the rotation resistance of the swing arm 22 is increased, so that the swing arm 22 rotates at a relatively slow speed, and the swing ring shaft 21 is not subjected to excessive force, thereby protecting the swing ring shaft 21 to a certain extent.
Specifically, in this scheme, the speed of swinging the swing arm 22 is slowed down by installing the resistance sleeve 3 in the box 1 and sleeved on the outer side of the swing ring shaft 21, that is, by increasing the swinging resistance of the swing ring shaft 21, and then, after the swing arm 22 swings to a vertically downward state, the damage to the swing ring shaft 21 is minimized.
The resistance sleeve 3 comprises a sliding ring 31 and a resistance ring 32 which are coaxially arranged, the resistance ring 32 is arranged between the sliding ring 31 and the swing arm 22, the resistance ring 32 is positioned in the box body 1, and in the scheme, when the resistance ring 32 is abutted against the inner wall of the box 1, the friction force between the two is the resistance when the swing ring shaft 21 rotates.
The resistance of the swinging ring shaft 21 is turned, the sliding ring 31 can axially reciprocate along the swinging ring shaft 21, the movement of the resistance ring 32 is directly controlled by the movement of the sliding ring 31, and when the sliding ring 31 approaches and abuts against the resistance ring 32, the resistance ring 32 moves synchronously with the swinging ring.
It should be noted that in this case, an elastic reset structure is provided between the resistance ring 32 and the case 1, the resistance ring 32 elastically slides on the outer side of the swing ring shaft 21, an annular cavity is provided at one end of the case 1 facing the resistance ring 32, the swing ring shaft 21 coaxially passes through the middle of the annular cavity, a reset spring 12 is provided in the annular cavity, one side of the resistance ring 32 facing the reset spring 12 is abutted against the reset spring 12, when the resistance ring 32 is pushed by the sliding ring 31, the reset spring 12 is compressed, and when the sliding ring 31 is not abutted against the resistance ring 32 any more, the sliding ring 31 is reset under the action of the reset spring 12, so that the rotation of the swing ring shaft 21 is not resisted by the resistance ring 32 formed on the case 1.
Further, the drag ring 32 slides on the wobble shaft 21 in a guiding manner and can reciprocate along the wobble shaft 21, a guide rail is provided on the outer side of the wobble shaft 21, a sliding groove matched with the guide rail is provided on the drag ring 32, when the wobble shaft 21 rotates, the drag ring 32 rotates synchronously, one end contacted with the return spring 12 is smooth, friction force generated by the drag ring 32 and the drag ring is negligible, and the return spring 12 is only an elastic structure for returning the drag ring 32, not limited in particular, but also an elastic pad, a butterfly spring and the like.
In order to increase the friction between the resistance ring 32 and the case 1, a contact piece 33 is provided on the side of the resistance ring 32 facing the case 1, the contact piece 33 is made of rubber and is ring-shaped, and when the driving shaft 11 stops rotating, the sliding ring 31 moves towards the side of the resistance ring 32 and pushes the resistance ring 32 to move axially along the wobble ring shaft 21 until the contact piece 33 abuts against the inner wall of the case 1, thereby increasing the resistance of the wobble ring shaft 21 to rotate.
In this case, two guiding sliding rails are disposed along the axial direction of the swing ring shaft 21 along the sliding ring 31 in the case 1, and two guiding sliding rails are disposed and symmetrically distributed with the swing ring shaft 21 as the center, and the sliding ring 31 is sleeved on the outer side of the swing ring shaft 21 and the upper and lower sides of the sliding ring 31 are respectively in guiding sliding fit with the guiding sliding rails.
The sliding ring 31 includes two parts, including a housing structure capable of sliding on a guiding sliding rail and a turntable 312 disposed at one end of the sliding ring 31 facing the resistance ring 32, the turntable 312 is rotatably mounted on the housing structure, and the specific shaft seat structure is a well-known technology, which is not described herein, and a ball 313 is disposed on an end surface of the turntable 312 facing one side of the resistance ring 32, when the turntable 312 moves toward one side of the resistance ring 32 and pushes the resistance ring 32 to move toward one side of the case 1, the turntable 312 contacts with the resistance ring 32 and rotates synchronously with the rotation of the swing shaft 21.
Specifically, the reciprocating movement of the housing structure is not particularly limited, in this case, the axial direction of the driving shaft 11 is provided with two parallel guide grooves 311, the two guide grooves 311 are symmetrically distributed by taking the wobble ring shaft 21 as the center, one side end surface, close to the wobble ring 2, of the guide groove 311 is inclined, two abutting rods 13 capable of moving towards the inside of the guide groove 311 are arranged on the box body 1, the two abutting rods 13 are symmetrically distributed by taking the driving shaft 11 as the center, and the inclined surfaces in the guide groove 311 are positioned on the moving path of the abutting rods 13.
Moreover, the deeper the driving shaft 11 stretches into the guiding groove 311, the larger the interference force that the sliding ring 31 can provide to the resistance ring 32, the larger the resistance that the swinging ring shaft 21 naturally swings, and the more the guiding groove 311 in the shell structure is far away from one end of the driving shaft 11 and penetrates through the side wall of the shell structure to form an opening, after the interference rod 13 stretches into completely, the interference rod 13 can pass through the opening, the matching strength between the interference rod 13 and the shell structure is increased, and the application resistance to the resistance ring 32 is the largest at this time.
When the two abutting rods 13 move towards the inside of the guide groove 311, they gradually abut against the inclined surface in the guide groove 311, and the shell structure starts to move along with the penetration of the abutting, so that the turntable 312 pushes the resistance ring 32 to move towards the inner wall of the case 1 until the contact piece 33 on the resistance ring 32 abuts against the case 1, increasing the rotation resistance of the resistance ring 32, and further slowing the rotation of the swing ring shaft 31.
It is noted that the driving mechanism for driving the reciprocating movement of the abutment lever 13 may be constructed by a motor, an electric push rod, or the like, and the driving mechanism for driving the linear movement of the abutment lever 13 is electrically connected to the driving mechanism for controlling the drive shaft 11.
In practice, when the driving mechanism controlling the driving shaft 11 stops working, an electrical signal is sent to the driving mechanism driving the contact rod 13 to reciprocate, so that the contact rod 13 starts to move toward the guide slot 311, and when the swing arm 22 needs to start swinging, the driving mechanism controlling the driving shaft 11 has a buffering time of several tens milliseconds before starting working, and before the buffering time, the driving mechanism driving the contact rod 13 to move starts to correspond, so that the contact rod 13 is separated from the guide slot 311.
Before the driving shaft 11 starts to rotate, the driving structure driving the contact rod 13 to move is used for leading the two contact rods 13 to withdraw from the guide groove 311 before the driving shaft 11 rotates, the sliding ring 31 is reset under the action of the reset spring 12, and in the scheme, magnetic coatings are respectively arranged on the corresponding end surfaces of the sliding ring 31 and the resistance ring 32, and the sliding ring 31 and the resistance ring 32 are magnetically repulsed, so that the turntable 312 on one side of the sliding ring 31 can be rapidly separated from the end surface of the resistance ring 32, the turntable 312 is not contacted with the resistance ring 32 any more, and the resistance when the resistance ring 32 rotates is reduced.
The whole abutting rod 13 is made of metal, the whole material is hard, a cavity is formed in the abutting rod 13 along the length direction of the abutting rod 13, a damping rubber strip 14 is arranged in the cavity, openings 131 communicated with the cavity are formed in two side ends of the abutting rod 13 respectively, and two sides of the damping rubber strip 14 penetrate out of the openings 131 in two sides of the abutting rod 13.
Therefore, when the abutting rod 13 abuts against the guide groove 311, the abutting rod 13 is tightly attached to the guide groove 311, and the swing ring shaft 21 generates noise due to the swing of the swing arm 22, and the damping rubber strip 14 dampens the noise generated by the transmitted vibration, and simultaneously reduces the noise generated by a large number of bearings in the box 1 during operation, so that in practice, an air bag or some sound absorbing materials can be used for replacing the bearing, and the bearing is not particularly limited herein.
