Description

Technical Field

[0001] This application relates to the field of cotton-grabbing equipment technology, and in particular to a body structure for a cotton-grabbing machine. Background Technology

[0002] A cotton grabber, also known as a bale grabber, is a machine in a cotton opening and cleaning unit used to grab cotton fibers from cotton bales. It is usually located at the beginning of the unit and comes in various types, such as top-grabbing, bottom-grabbing, reciprocating trolley, and rotary trolley types. The main function of the cotton grabber is to mechanically grab fibers from the surface of the cotton bale and then transport them to subsequent machines for processing via airflow or mechanical means.

[0003] Chinese Patent No. CN110004524B discloses a cotton grabbing machine, including a support unit, which includes a central support platform and a central shaft and a traveling component respectively fixed at both ends of the support platform. The support unit also includes a first drive component. The traveling component includes a vertically arranged support plate and a traveling wheel disposed at the bottom of the support plate. The first drive component can drive the traveling wheel to rotate. The first drive component can be a motor, which is connected to a pulley coaxially connected to the traveling wheel through a belt drive.

[0004] During the use of the above technology, the entire machine body rotates around the central axis. However, when the equipment grabs cotton, the large load-bearing force of the entire machine body will act on the traveling wheels, causing the traveling wheels to be subjected to a large friction force. As the machine body is driven to rotate by the motor and pulley, the large load-bearing force of the machine body can easily cause the belt to slip, which in turn prevents the machine body from rotating smoothly. This will affect the operation of the cotton grabber, reduce the cotton conveying efficiency, and has shortcomings. Utility Model Content

[0005] In order to improve the problem of belt slippage caused by the load-bearing capacity of the machine body acting on the walking wheels, which prevents the machine body from rotating smoothly, this application provides a machine body structure for a cotton grabbing machine.

[0006] The technical solution for the body structure of a cotton grabber provided in this application is as follows:

[0007] A body structure for a cotton grabber includes a base plate, a rotating cylinder, and a cotton grabbing frame. The cotton grabbing frame is disposed on the rotating cylinder, and the rotating cylinder is rotatably disposed on the base plate. A traveling wheel is rotatably disposed at one end of the cotton grabbing frame facing away from the rotating cylinder. A rotary bearing is disposed between the base plate and the rotating cylinder, and a driving component for driving the rotating cylinder to rotate is disposed on the base plate.

[0008] By adopting the above technical solution, the slewing bearing shares most of the weight of the cotton grabbing frame and the rotating cylinder, thereby reducing the weight on the traveling wheels and thus reducing the friction on the traveling wheels. When the drive component drives the rotating cylinder to rotate, the slewing bearing reduces the friction when the rotating cylinder rotates, so that the cotton grabbing frame can rotate smoothly around the rotating cylinder.

[0009] Optionally, the driving component includes an internal gear ring disposed on the base plate, the slewing bearing coaxially sleeved on the internal gear ring, a drive motor electrically connected to the control system disposed on the rotating cylinder, and a gear coaxially disposed on the output shaft of the drive motor that meshes with the internal gear ring.

[0010] By adopting the above technical solution, the control system starts the drive motor, and the output shaft of the drive motor drives the gear to rotate. Since the gear meshes with the internal gear ring, the reaction force of the gear rotation causes the rotating cylinder to rotate around the axis of the internal gear ring. The meshing relationship between the gear and the internal gear ring can ensure that the rotating cylinder drives the cotton grabbing frame to rotate stably, thereby improving the cotton grabbing efficiency.

[0011] Optionally, the base plate is provided with a conduit coaxial with the slewing bearing. A connecting ring tube is coaxially provided on the conduit, and multiple conductive rings are sleeved on the connecting ring tube along its axial direction. A cable is passed through the conduit, and multiple wires on the cable correspond one-to-one with and are electrically connected to the multiple conductive rings. A cable holder is provided on the rotating cylinder, and an outer ring cylinder is provided on the cable holder. The outer ring cylinder is coaxially sleeved on the connecting ring tube, and multiple external wires are provided on the outer ring cylinder. Each external wire corresponds one-to-one with a conductive ring, and an elastic conductive element for conducting electricity is provided between the external wire and the conductive ring.

[0012] By adopting the above technical solution, when the rotating cylinder rotates, the cable tie frame drives the outer ring cylinder to rotate around the axis of the connecting ring tube. At the same time, the elastic conductive element conducts the current on the conductive ring to the external conductor, thereby achieving stable current transmission and reducing the possibility of the cable being twisted off by rotation.

[0013] Optionally, the elastic conductive element includes a graphite brush slidably disposed on the outer ring cylinder. A conductive groove for sliding the graphite brush is formed between the inner and outer walls of the outer ring cylinder. A sealing block is provided on the outer wall of the outer ring cylinder to seal the conductive groove. A conductive voltage spring is supported between the graphite brush and the sealing block. The external wire passes through the sealing block and is electrically connected to the conductive voltage spring.

[0014] By adopting the above technical solution, as the external ring cylinder rotates continuously around the axis of the connecting ring tube, the current flows sequentially along the cable, conductive ring, graphite brush, conductive voltage spring and external wire. At the same time, the graphite brush wears down continuously in the sliding friction with the conductive ring, while the conductive voltage spring will always press the graphite brush tightly on the conductive ring, thereby ensuring the stability of the current on the cable.

[0015] Optionally, a protective cylinder is provided inside the rotating cylinder, and the electrical beam frame is disposed inside the protective cylinder.

[0016] By adopting the above technical solution, the possibility of external debris entering the protective cylinder and affecting the stability of the current output is reduced.

[0017] Optionally, the cotton-grabbing frame extends into the interior of the rotating cylinder at one end near the rotating cylinder, an inspection door is rotatably provided at the top of the rotating cylinder, a ladder is provided on the cotton-grabbing frame inside the rotating cylinder, and a locking device is provided between the inspection door and the cotton-grabbing frame, the locking device being used to fix the inspection door on the cotton-grabbing frame.

[0018] By adopting the above technical solution, when the rotating cylinder is damaged during operation, maintenance personnel can release the locking mechanism, open the inspection door at the top of the rotating cylinder, and finally enter the interior of the rotating cylinder via a ladder. This facilitates the maintenance of the internal components of the rotating cylinder and helps reduce the possibility of external cotton entering the interior of the rotating cylinder.

[0019] Optionally, the locking element includes a locking bolt bolted to the cotton grabbing frame, a U-shaped locking groove plate slidably disposed on the inspection door, an L-shaped mounting plate disposed on the inspection door, a guide post disposed on the inspection door, the guide post slidingly passing through the locking groove plate, a locking compression spring supporting the locking groove plate and the mounting plate, the locking compression spring being used to press the locking groove plate tightly onto the inspection door, the locking bolt being used to press the locking groove plate tightly onto the cotton grabbing frame, and a U-shaped pressing groove being provided on the inspection door for the locking bolt to pass through.

[0020] By adopting the above technical solution, maintenance personnel can loosen the locking bolts and then push the locking groove plate. The clamping groove on the locking groove plate separates from the locking bolts, and at the same time, the locking groove plate compresses the locking spring. The locking spring deforms under pressure, and then the maintenance personnel can rotate the inspection door.

[0021] Optionally, an assembly door is detachably provided on the circumferential outer wall of the rotating cylinder, and a guide slope is provided at the assembly door of the rotating cylinder.

[0022] By adopting the above technical solution, the assembly door reduces the possibility of cotton entering the rotating cylinder, and at the same time facilitates the transfer of components assembled inside the rotating cylinder from the guide ramp into the rotating cylinder.

[0023] Optionally, a plurality of surrounding plates are evenly arranged around the periphery of the rotating cylinder, and a column is provided between each two adjacent surrounding plates. The surrounding plates are located between the traveling wheel and the rotating cylinder, and a door plate is rotatably arranged between two columns, with a pin inserted into the door plate.

[0024] By adopting the above technical solution, the separate design of the enclosure and columns makes it convenient for workers to assemble. At the same time, workers can change the size of the door panel and enclosure by changing the distance between the columns, thereby adapting to different application scenarios.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The slewing bearing distributes most of the weight of the cotton grabbing frame and the rotating cylinder, thereby reducing the weight on the traveling wheels and thus reducing the friction on the traveling wheels. When the drive unit drives the rotating cylinder to rotate, the slewing bearing reduces the friction when the rotating cylinder rotates, so that the cotton grabbing frame can rotate smoothly around the rotating cylinder.

[0027] 2. The control system starts the drive motor, and the output shaft of the drive motor drives the gear to rotate. Since the gear meshes with the internal gear ring, the reaction force of the gear rotation causes the rotating cylinder to rotate around the axis of the internal gear ring. The meshing relationship between the gear and the internal gear ring can ensure that the rotating cylinder drives the cotton grabbing frame to rotate stably, thereby improving the cotton grabbing efficiency.

[0028] 3. As the external ring cylinder rotates continuously around the axis of the connecting ring tube, the current flows sequentially along the cable, the conductive ring, the graphite brush, the conductive voltage spring, and the external wire. At the same time, the graphite brush wears down continuously due to sliding friction with the conductive ring, while the conductive voltage spring always presses the graphite brush tightly against the conductive ring, thereby ensuring the stability of the current on the cable.

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] This application discloses a body structure for a cotton grabber.

[0037] Reference Figure 1 A body structure for a cotton grabber includes a base plate 1, a rotating cylinder 2, and a cotton grabber frame 3. Expansion bolts 21 are bolted to the base plate 1. The cotton grabber frame 3 is arranged on the rotating cylinder 2. The rotating cylinder 2 is rotatably arranged on the base plate 1. A traveling wheel 4 is rotatably connected to the end of the cotton grabber frame 3 facing away from the rotating cylinder 2. Several surrounding plates 22 are evenly arranged around the periphery of the rotating cylinder 2.

[0038] Reference Figure 1 and Figure 2 Each of the two adjacent enclosure panels 22 is provided with a column 23, which is bolted to the ground. The enclosure panel 22 is located between the traveling wheel 4 and the rotating cylinder 2. A door panel 24 is rotatably connected between the two columns 23. A pin 25 is inserted into the door panel 24 for insertion into the ground.

[0039] Reference Figure 1 and Figure 3 A slewing bearing 5 is arranged between the base plate 1 and the rotating cylinder 2. A driving component 6 for driving the rotating cylinder 2 to rotate is arranged on the base plate 1. The driving component 6 includes an internal gear ring 61 bolted to the base plate 1. The slewing bearing 5 is coaxially sleeved on the internal gear ring 61. A drive motor 62 electrically connected to the control system is bolted to the bottom of the rotating cylinder 2. A gear 63 coaxially welded to the output shaft of the drive motor 62 and meshing with the internal gear ring 61 is also present.

[0040] The worker starts the drive motor 62 through the control system. The output shaft of the drive motor 62 drives the gear 63 to rotate. Since the internal gear ring 61 is fixed on the base plate 1 and meshes with the gear 63, the reaction force of the rotation of the gear 63 causes the rotating cylinder 2 to rotate around the axis of the internal gear ring 61, thereby causing the rotating cylinder 2 to drive the cotton grabbing frame 3 to rotate around the axis of the rotating cylinder 2.

[0041] Reference Figure 3 and Figure 4 A conduit 7, coaxial with the slewing bearing 5, is bolted to the base plate 1. A connecting ring tube 8 is coaxially bolted to the conduit 7. The connecting ring tube 8 can be made of insulating material. Multiple conductive rings 9 are sleeved on the connecting ring tube 8 along its axial direction. A cable 10 is threaded through the conduit 7. Multiple wires on the cable 10 correspond one-to-one with and are electrically connected to the multiple conductive rings 9.

[0042] Reference Figure 3 and Figure 4 A hollow protective cylinder 15 with an open bottom is coaxially bolted inside the rotating cylinder 2. A cable tie frame 11 is bolted inside the protective cylinder 15. The cable tie frame 11 can be made of insulating material. An outer ring cylinder 12 is bolted to the cable tie frame 11. The outer ring cylinder 12 is coaxially sleeved on the wiring ring tube 8. Multiple external wires 13 are arranged on the outer ring cylinder 12. The external wires 13 correspond one-to-one with the conductive rings 9. An elastic conductive element 14 for conducting electricity is arranged between the external wires 13 and the conductive rings 9.

[0043] Reference Figure 3 and Figure 4 The elastic conductive element 14 includes a plurality of graphite brushes 141 slidably arranged on the outer ring cylinder 12. Each graphite brush 141 corresponds to a conductive ring 9. A conductive groove 142 for sliding of the graphite brushes 141 is provided between the inner and outer walls of the outer ring cylinder 12. A sealing block 143 is bolted to the outer wall of the outer ring cylinder 12. The sealing block 143 is used to seal the conductive groove 142. A conductive voltage spring 144 supports the graphite brushes 141 and the sealing block 143. An external wire 13 passes through the sealing block 143 and is electrically connected to the conductive voltage spring 144.

[0044] During the rotation of the cotton grabbing frame 3, the rotating cylinder 2 drives the protective cylinder 15 to rotate synchronously. The protective cylinder 15 drives the outer ring cylinder 12 to rotate synchronously through the electric current frame 11. The outer ring cylinder 12 rotates continuously around the axis of the connecting ring tube 8. The current from the cable 10 flows to the outer conductor 13 in sequence along the conductive ring 9, the graphite brush 141 and the conductive spring 144.

[0045] This provides power to the electrical components on the rotating cylinder 2. Meanwhile, the graphite brush 141 wears down continuously due to sliding friction with the conductive ring 9, while the elastic force of the conductive spring 144 keeps the graphite brush 141 pressed against the conductive ring 9, thereby ensuring the stability of the current on the incoming cable 10.

[0046] Reference Figure 3 The cotton grabbing frame 3 extends into the interior of the rotating cylinder 2 from one end near the rotating cylinder 2. An assembly door 19 is bolted to the outer circumferential wall of the rotating cylinder 2, and a guide slope 20 is arranged at the assembly door 19 of the rotating cylinder 2.

[0047] Reference Figure 1 , Figure 3 and Figure 5 The top of the rotating cylinder 2 is rotatably connected to an L-shaped inspection door 16. A ladder 17 is welded onto the cotton grabbing frame 3 inside the rotating cylinder 2. A locking element 18 is arranged between the inspection door 16 and the cotton grabbing frame 3. The locking element 18 is used to fix the inspection door 16 onto the cotton grabbing frame 3.

[0048] Reference Figure 1 , Figure 3 and Figure 5 The locking component 18 includes a locking bolt 181 bolted to the cotton grabber 3, a U-shaped locking groove plate 182 slidably arranged on the inspection door 16, an L-shaped mounting plate 183 welded on the inspection door 16, a guide post 184 welded on the inspection door 16, and the locking groove plate 182 slidably sleeved on the guide post 184.

[0049] Reference Figure 3 and Figure 5 A locking spring 185 is provided between the locking groove plate 182 and the mounting plate 183. The locking spring 185 is used to press the locking groove plate 182 onto the inspection door 16. The locking bolt 181 is used to press the locking groove plate 182 onto the cotton grabbing frame 3. The inspection door 16 is provided with a pressing groove 186 with a U-shaped cross-section for the locking bolt 181 to pass through.

[0050] When the cotton grabber 3 needs maintenance, the maintenance personnel loosen the locking bolt 181 and then push the locking groove plate 182 downward. The pressing groove 186 on the locking groove plate 182 separates from the locking bolt 181. At the same time, the locking groove plate 182 compresses the locking spring 185. The locking spring 185 deforms under pressure. Then, the maintenance personnel turn and open the inspection door 16 and enter the interior of the rotating cylinder 2 through the ladder 17 to repair the internal components of the rotating cylinder 2.

[0051] The implementation principle of the body structure of a cotton grabber according to an embodiment of this application is as follows: the worker starts the drive motor 62 through the control system, and the output shaft of the drive motor 62 drives the gear 63 to rotate. Since the internal gear ring 61 is fixed on the base plate 1 and meshes with the gear 63, the reaction force of the rotation of the gear 63 causes the rotating cylinder 2 to rotate around the axis of the internal gear ring 61, thereby causing the rotating cylinder 2 to drive the cotton grabber frame 3 to rotate around the axis of the rotating cylinder 2.

[0052] During the rotation of the cotton grabbing frame 3, the rotating cylinder 2 drives the protective cylinder 15 to rotate synchronously. The protective cylinder 15 drives the outer ring cylinder 12 to rotate synchronously through the electric current frame 11. The outer ring cylinder 12 rotates continuously around the axis of the connecting ring tube 8. The current from the cable 10 flows to the outer conductor 13 in sequence along the conductive ring 9, the graphite brush 141 and the conductive spring 144.

[0053] This provides power to the electrical components on the rotating cylinder 2. Meanwhile, the graphite brush 141 wears down continuously due to sliding friction with the conductive ring 9, while the elastic force of the conductive spring 144 keeps the graphite brush 141 pressed against the conductive ring 9, thereby ensuring the stability of the current on the incoming cable 10.

[0054] When the cotton grabber 3 needs maintenance, the maintenance personnel loosen the locking bolt 181 and then push the locking groove plate 182 downward. The pressing groove 186 on the locking groove plate 182 separates from the locking bolt 181. At the same time, the locking groove plate 182 compresses the locking spring 185. The locking spring 185 deforms under pressure. Then, the maintenance personnel turn and open the inspection door 16 and enter the interior of the rotating cylinder 2 through the ladder 17 to repair the internal components of the rotating cylinder 2.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
