[0004] In the above-mentioned reciprocating plucking machine, the plucking device 03 is installed on the turret rotating part 02 with a cantilever structure, which has the following problems: (1) In order to ensure the installation performance and movement performance of the plucking device 03, the working width of the plucking device 03 is often greatly limited, and the working width of the plucking device 03 affects the maximum output and the single bale discharge volume of the plucking device. In other words, the working width of the plucking device 03 is relatively small, and the maximum output and the single bale discharge volume affect the mixing effect of multiple batches of raw materials; (2) It needs to be used with a counterweight 05, and the counterweight 05 is used to adjust the rise and fall of the plucking device 03. For example, when the plucking device 03 rises, the counterweight 05 falls; when the plucking device 03 falls, the counterweight 05 rises.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to Figures 3 to 6 , Figure 3 A schematic diagram of the structure of a reciprocating cotton plucking machine provided in an embodiment of the present application; Figure 4 for Figure 3 Schematic diagram along AA direction; Figure 5 A schematic diagram of the partial structure of the reciprocating cotton plucking machine provided in an embodiment of the present application at the fixed pulley; Figure 6 A schematic diagram of the partial structure of the reciprocating cotton plucking machine at the roller provided in an embodiment of the present application.

[0036] For reference Figure 3The present application provides a reciprocating cotton picking machine, comprising a traveling device that can move along a rail, a movable support 1 that can move along the ground, and a cotton picking device 2 for picking up cotton material; in this embodiment, the movable support 1 is arranged on one side of the traveling device and is rotatably connected to the traveling device with the traveling device as the rotation center. At the same time, a connecting portion that can realize rotation locking is provided between the movable support 1 and the traveling device; the cotton picking device 2 is arranged between the traveling device and the movable support 1, and is used to pick up cotton material from a cotton material carrier such as a conveyor belt; in this embodiment, the cotton picking device 2 is suspended above the cotton material carrier, and can pick up cotton material from a cotton material carrier such as a conveyor belt to realize the transfer of cotton material. In addition, the structural form of the cotton material can also be changed during the process of picking up the cotton material.

[0037] In this embodiment, the movable support 1 can move along the ground; the traveling device can move along the rail, for example, the traveling device can translate along the linear rail; a connecting portion that can realize rotation locking is provided between the aforementioned movable support 1 and the aforementioned traveling device. When the connecting portion causes the movable support 1 and the traveling device to be rotationally locked, the movable support 1 and the traveling device are relatively fixed in the rotation direction of the movable support 1, so when the traveling device moves along the rail, it can drive the movable support 1 to move synchronously. Conversely, when the connecting portion releases the rotation lock between the movable support 1 and the traveling device, the movable support 1 can rotate around the traveling device to realize rotation from one side of the traveling device to the other side of the traveling device.

[0038] Usually, the walking device adopts a double ground rail design, that is, the walking device can move along the double ground rail; the aforementioned walking device can be provided with four walking rollers, and the four walking rollers are located on the double ground rails, and can move along the rails under the drive of the motor of the walking device. Among them, a cotton conveying air duct can be provided between the double ground rails, and the cotton material grabbed by the cotton grabbing device 2 is transported to the specified position by the aforementioned cotton conveying air duct. The movable support 1 can move along the ground, including the bottom end of the movable support 1 directly contacting the ground and moving relative to the ground, and also including the bottom end of the movable support 1 walking on a track flush with the ground.

[0039] In this embodiment, the cotton grabbing device 2 has a working width; the working width of the cotton grabbing device 2 is perpendicular to the moving direction of the cotton grabbing device 2 and parallel to the parallel distribution direction of the walking device and the movable support 1. Taking the cotton material carrier as a conveyor belt as an example, the walking device can move along the length direction of the conveyor belt, and the walking device and the movable support 1 are arranged side by side along the width direction of the conveyor belt. Therefore, the working width of the cotton grabbing device 2 is parallel to the width direction of the conveyor belt. At this time, the working width of the cotton grabbing device 2 can be regarded as the grabbing range of the cotton grabbing device 2 in the width direction of the conveyor belt.

[0040] In summary, it can be seen that in this embodiment, on the one hand, the traveling device and the movable support 1 can be assembled to form a support with a gantry structure, and the cotton grabbing device 2 is arranged between the traveling device and the movable support 1, and the cotton grabbing device 2 is respectively positioned and connected to the aforementioned support along the two ends of its own working width. Compared with the common cantilever installation method, the installation method of the cotton grabbing device 2 on the aforementioned support is conducive to expanding the working width of the cotton grabbing device 2 and improving the positioning and installation effect of the cotton grabbing device 2; on the other hand, the movable support 1 can move synchronously with the traveling device and can also rotate around the traveling device, which improves the movement flexibility of the traveling device and the cotton grabbing device 2 and is conducive to expanding the working area of ​​the cotton grabbing device 2. For example, cotton material carriers can be respectively arranged on two opposite sides of the traveling device and the track. The cotton grabbing device 2 first moves and grabs the cotton material on one side of the aforementioned track, and then rotates to the other side of the aforementioned track with the traveling device to realize moving and grabbing the cotton material on the other side of the aforementioned track. In short, cotton grabbing can be realized in double-sided areas.

[0041] The reciprocating cotton plucking machine provided in the present application is further explained below in conjunction with the accompanying drawings and implementation methods.

[0042] For reference Figure 3 In some embodiments, the movable support 1 is arranged on one side of the traveling device, and may include a support beam 11 and a support column 12; the bottom end of the aforementioned support column 12 is provided with a roller that can roll close to the ground; the aforementioned support beam 11 is arranged transversely along the parallel distribution direction of the traveling device and the movable support 1, and the two ends of the support beam 11 are respectively connected to the traveling device and the support column 12. In this embodiment, the cotton grabbing device 2 is positioned and installed on the support beam 11, that is, the two ends of the cotton grabbing device 2 along its own working width are respectively positioned and installed on the support beam 11. Usually, the working width of the cotton grabbing device 2 is slightly smaller than the length of the support beam 11, and the two ends of the cotton grabbing device 2 along its own working width are correspondingly adjacent to the two ends of the support beam 11.

[0043] In the above embodiment, the walking device and the movable support 1 are assembled to form a support with a gantry structure, the support beam 11 can be regarded as the crossbeam of the support, and the walking device and the support column 12 can be regarded as the two side legs of the support. Since the cotton grabbing device 2 is installed on the support beam 11 and suspended above the cotton carrier, it can be seen that the support beam 11 spans the cotton carrier, and the walking device and the support column 12 are respectively located on both sides of the cotton carrier.

[0044] On the basis of the above embodiment, the connection part of the reciprocating plucking machine may include a turret; the turret is arranged between the traveling device and the movable support 1, and the turret has a self-rotation characteristic, which can make the traveling device and the movable support 1 rotate relative to each other, thereby realizing the rotation of the movable support 1 around the traveling device. Usually, the traveling device is arranged at the bottom of the turret, and the movable support 1 is arranged at one side of the turret and fixedly connected to the turret.

[0045] The turret can be driven to rotate by related power equipment or manually pushed.

[0046] The turret can be connected to the walking device through a four-point contact bearing. When the turret is driven to rotate by a relevant power device, the turret can rotate around the center of the aforementioned four-point contact bearing under the drive of the corresponding power device, such as a motor, and the rotation amplitude can be 180° or other suitable values.

[0047] When the turret is driven to rotate by the relevant power equipment, if the power equipment stops running, the turret stops rotating. At this time, the turret can realize the rotation locking of both the movable support 1 and the walking device. Conversely, if the power equipment starts running, the turret rotates. At this time, the turret can release the rotation locking of both the movable support 1 and the walking device.

[0048] When the turret is pushed and rotated manually, the turret can rely on its own rotational resistance or a specific locking device to achieve rotational locking of the mobile support 1 and the traveling device. For example, if the rotational resistance of the turret is greater than the movement resistance of the mobile support 1, the traveling device will not cause the turret to rotate when driving the mobile support 1 to move. In other words, when the turret needs to be rotated, the operator needs to apply a force that is significantly greater than the movement resistance of the mobile support 1 to push the turret to rotate. Of course, in order to reduce the workload of the operator, the turret can also be provided with a specific locking device. When the locking device is turned on, the locking device prevents the turret from rotating, thereby preventing the operator from pushing and turning the mobile support 1. Conversely, when the locking device is closed, the locking device releases the lock on the turret, and the operator can push and turn the mobile support 1.

[0049] In the above embodiment, the sizes of the turret and the traveling device can be adjusted according to actual needs. When the size of the turret, especially the height, is significantly larger than the corresponding parameters of the traveling device, the turret mainly serves as a leg of the gantry-shaped support, and vice versa, when the size of the traveling device, especially the height, is significantly larger than the corresponding parameters of the turret, the traveling device mainly serves as a leg of the gantry-shaped support.

[0050] For reference Figure 3 and Figure 4 On the basis of the above embodiment, the cotton grabbing device 2 may include a cotton grabber 21 for grabbing cotton from the cotton carrier and a cotton passing pipe 22 for sucking the cotton; wherein the cotton grabber 21 is connected to the entrance of the cotton passing pipe 22, and at the same time, the cotton grabber 21 is arranged on the movable support 1 and is used to be suspended above the cotton carrier, and the cotton grabber 21 is positioned and connected to the support beam 11 at both ends along its working width. In this embodiment, the cotton grabber 21 and the cotton passing pipe 22 form a passage, the cotton grabber 21 grabs cotton from the cotton carrier, and the cotton passing pipe 22 can suck and transfer the cotton at the cotton grabber 21. Obviously, the transfer path of the cotton depends on the pipeline distribution path of the cotton passing pipe 22.

[0051] In the above embodiment, the cotton passing pipeline 22 may include a first pipeline 221, a second pipeline 222, a rotating joint 223, and a telescopic pipeline 224 that can be extended and retracted in the vertical direction; wherein the first pipeline 221 is fixed, the two ends of the second pipeline 222 are respectively connected to the first pipeline 221 and the telescopic pipeline 224, the rotating joint 223 is arranged between the first pipeline 221 and the second pipeline 222, and the cotton grabber 21 is arranged at the other end of the telescopic pipeline 224. It can be seen that the cotton material grabbed by the cotton grabber 21 can be transported to a specific position along the telescopic pipeline 224, the second pipeline 222, and the first pipeline 221 in sequence.

[0052] The telescopic pipe 224 of the cotton passing pipe 22 is connected to the cotton grabber 21, so that the cotton grabber 21 has space for lifting and lowering movement in the vertical direction; the first pipe 221, the second pipe 222 and the telescopic pipe 224 are connected in sequence. Compared with the telescopic pipe 224, there are no specific requirements for the structural characteristics of the first pipe 221 and the second pipe 222. For example, the first pipe 221 and the second pipe 222 can both be set as rigid pipes, or they can both be set as hoses.

[0053] In addition, the first pipe 221 and the second pipe 222 can be regarded as the main part of the above-mentioned cotton passing pipe 22, which is often longer and has a more complicated extension path. In order to take into account the rotation characteristics of the movable support 1 and the cotton grasping device 2 and the layout of the telescopic pipe 224, in this embodiment, the first pipe 221 and the second pipe 222 are separately arranged and rotatably connected through a rotating joint 223. The aforementioned first pipe 221 is fixed, thereby ensuring the layout of the main part of the telescopic pipe 224. The aforementioned second pipe 222 and the aforementioned first pipe 221 can rotate relative to each other at the rotating joint 223, thereby satisfying the rotation characteristics of the movable support 1 and the cotton grasping device 2.

[0054] For reference Figure 3 On the basis of the above embodiment, the first pipe 221 and the second pipe 222 are both configured as rigid pipes, and the first pipe 221 is vertically distributed and penetrates the turret 3, and the turret 3 rotates around the first pipe 221. In this example, the first pipe 221 can be used as a passage for transporting cotton materials and as an installation base for the turret 3, which can reasonably and effectively integrate the first pipe 221 and the turret 3, improve space utilization, and simplify the installation arrangement of the cotton pipe 22.

[0055] For reference Figure 3 and Figure 6In the embodiments provided above, the mobile support 1 can move along the rail with the traveling device, and can also rotate around the traveling device. In order to meet the aforementioned motion characteristics of the mobile support 1, a universal wheel can be provided at the bottom of the mobile support 1. At the same time, an orientation device for limiting the deflection of the rotating shaft of the universal wheel is also provided at the bottom of the support column 12. When the orientation device is turned on, the orientation device prevents the deflection of the rotating shaft of the universal wheel. At this time, the aforementioned universal wheel is equivalent to an orientation wheel, which is conducive to improving the motion performance of the mobile support 1 during translation. On the contrary, when the orientation device is turned off, the orientation device releases the restriction on the rotating shaft of the roller 7. At this time, the rotating shaft of the aforementioned universal wheel can deflect with the movement of the mobile support 1, which can meet the motion characteristics requirements of the mobile support 1 during rotation.

[0056] In addition to the above examples, in order to ensure the various motion characteristics requirements of the mobile support 1, the roller 7 may include a first directional wheel and a second directional wheel, and the rotating axes of the first directional wheel and the second directional wheel intersect. Usually, the rotating axis of the first directional wheel is parallel to the working width of the cotton grabbing device 2, which is beneficial to ensure that the mobile support 1 moves along a straight line trajectory. The rotating axis of the second directional wheel is inclined to the rotating axis of the first directional wheel, which can meet the motion characteristics requirements of the mobile support 1 when it rotates.

[0057] For reference Figure 3 and Figure 4 In some embodiments, the cotton grabber 2 includes not only a cotton grabber 21 and a cotton passing pipe 22, but also a lifting belt 4 and a winding motor 5; wherein the cotton grabber 21 is arranged below the support beam 11, and two sets of lifting belts 4 are respectively arranged at both ends of the cotton grabber 21, and both sets of lifting belts 4 are connected between the cotton grabber 21 and the support beam 11, and the winding motor 5 is connected to the lifting belt 4, and the cotton grabber 21 can be driven to rise and fall through the lifting belt 4. In this embodiment, the cotton grabber 21 realizes that the two ends along its own working width are respectively positioned and connected to the two ends of the support beam 11 through the two sets of lifting belts 4. Usually, the two sets of lifting belts 4 are driven by the same winding motor 5 to ensure the movement synchronization of the two sets of lifting belts 4. It can be seen that in this embodiment, the cotton grabber 21 is fixedly suspended below the support beam 11 through the lifting belts 4 and other components.

[0058] For reference Figures 3 to 5 In the above embodiment, the cotton grabber 21 is positioned and installed on the support beam 11 of the mobile support 1 through two sets of lifting belts 4 and related parts. For example, the body of the winding motor 5 is fixed to the body of the cotton grabber 21. The cotton grabber 2 also includes a fixed pulley 6, which is arranged on the support beam 11. One end of the lifting belt 4 is connected to the winding motor 5 and the other end is connected to the cotton grabber 21. The middle part of the lifting belt 4 spans the fixed pulley 6. After starting the winding motor 5, the winding motor 5 retracts and releases the lifting belt 4. The lifting belt 4 uses the support beam 11 and the fixed pulley 6 as a fulcrum to lift the body of the winding motor 5 and the body of the cotton grabber 21, so as to realize the lifting and lowering of the cotton grabber 21.

[0059] Still available for reference Figures 3 to 5 In some embodiments, the cotton grabber 21 adopts a double-beater structure and a forward cotton grabbing technology. For example, the cotton grabber 21 may include a cotton grabber beater 211 for puncturing a cotton bale, a beater motor 212 for driving the cotton grabber beater 211 to rotate, and a transmission belt 213 disposed between the cotton grabber beater 211 and the beater motor 212. The cotton grabber beaters 211 are distributed in pairs and roll relative to each other, and can grab the cotton bundles in the cotton bale while puncturing the cotton bale, thereby achieving the grabbing of cotton materials. The beater motor 212 is connected to the cotton grabber beater 211 and can drive the cotton grabber beater 211 to rotate. For example, the beater motor 212 can drive a pair of cotton grabber beaters 211 distributed side by side to roll relative to each other. The transmission belt 213 is disposed between the cotton grabber beater 211 and the beater motor 212. The beater motor 212 transmits torque to the cotton grabber beater 211 through the transmission belt 213, thereby driving the cotton grabber beater 211 to rotate. As for other specific settings of the cotton grabber 21, please refer to Figure 4 , and reference may also be made to the relevant settings in the prior art.

[0060] In the above embodiment, the working principle of the cotton picking device 2 is as follows:

[0061] The cotton grabbing beater 211 has a beater blade, the tip of the beater blade penetrates into the interior of the hard cotton block on the surface of the cotton bale and tears off small cotton blocks from the aforementioned hard cotton blocks. Under the high-speed rotation of the cotton grabbing beater 211 and its beater blade, the torn off small cotton blocks are further loosened into small cotton bundles. These small cotton bundles are sucked into the funnel-shaped pipe opening of the cotton grabbing beater 211 under the negative pressure airflow provided by the cotton passing duct 22 and the related air duct structure, and then transported to the designated location along the cotton passing duct 22.

[0062] In summary, the reciprocating cotton plucker provided by the present application adopts a gantry structure to install the cotton plucker 21 of the cotton plucker 2. On the one hand, the balancing weight in the original design of the cotton plucker 21 can be eliminated, reducing safety hazards. On the other hand, it is conducive to increasing the working width of the cotton plucker 21. For example, the working width can be increased to 2900mm or 3500mm, thereby increasing the maximum output of the cotton plucker. After the working width of the cotton plucker 21 is increased, the cotton plucking area of ​​the cotton plucker 2 is increased, and the bale discharge volume is increased, which is conducive to the mixing of different batches of raw materials, so the cotton mixing effect can be improved.

[0063] The above is a detailed introduction to the reciprocating cotton plucking machine provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
