Description

Technical Field

[0001] The utility model relates to the technical field of hybrid excitation motors, in particular to an automatic folding driving platform for a cotton picker. Background Art

[0002] Currently, the platforms on both sides of the cotton pickers on the market are detachable platforms and need to be disassembled before transportation. Because the platforms are made of metal sheet metal and are heavy, they require more than two people to disassemble, which is time-consuming and labor-intensive. In addition, since there are many disassembled parts, they are easy to be lost if not stored properly. When reassembling after disassembly, the corresponding installation accuracy must be achieved, otherwise it will easily affect the performance of the entire vehicle.

[0003] In this regard, our company has proposed a utility model patent entitled "A Cotton Picker Folding Driving Platform and Cotton Picker", with the authorization announcement number CN219961383U. The application was published on November 7, 2023. The cotton picker folding driving platform disclosed therein includes a main frame, a right platform, a left platform and an armrest, and also includes a fixed bracket, which is detachably mounted on the rib plate or the folding platform. The right platform and the left platform each include at least two folding platforms, and a hinge is provided between the folding platform and the main frame. The hinge enables the folding platform to be in a working position and a folding position respectively. Each folding platform is provided with a handrail, and a rib plate is provided at both ends of the folding platform. When the folding platform is in the working position, the rib plate is mounted on the main frame by a first bolt assembly, and when the folding platform is in the folding position, the fixed bracket is installed between the main frame and the rib plate by the first bolt assembly.

[0004] The folding platform proposed in the above application can be folded and stored without disassembling the platform. However, there are still the following shortcomings in actual application: 1. The handrail and the platform need to be folded separately, and there is a sequence of folding, and the folding efficiency is poor; 2. The platform folding lacks mechanical assistance, and the weight of the platform is large, which makes the folding of the platform a safety hazard, and the folding efficiency also needs to be improved; 3. The platform is also equipped with other peripheral components such as fire extinguishers and extension ladders. Without removing the peripheral components, the platform cannot be folded into place, and there is a lack of reminder devices. Utility Model Content

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides an automatic folding driving platform for a cotton picker, aiming to improve the folding efficiency of the driving platform of the cotton picker.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The invention discloses an automatic folding driving platform for a cotton picker, comprising a main frame, a lateral platform and a lateral guardrail. The lateral guardrail and the main frame are rotatably connected to opposite sides of the lateral platform respectively. The main frame is provided with a linear driving device arranged at an angle to the lateral platform. A first connecting rod is rotatably provided on the main frame. A second connecting rod rotatably connected to the first connecting rod is fixedly provided on the lateral guardrail. The linear driving device rotatably connects the main frame and the lateral platform so that the linear driving device can drive the lateral platform to rotate relative to the main frame when performing linear extension and retraction, and the lateral platform drives the first connecting rod and the second connecting rod to rotate to realize synchronous folding or unfolding of the lateral platform and the lateral guardrail.

[0008] A linear drive device is used to provide folding assistance for the side platform and the side guardrail, with high folding efficiency and reliable folding action; the connecting rod assembly formed by the first connecting rod and the second connecting rod can synchronously drive the side guardrail to rotate around the side platform when the linear drive device drives the side platform to rotate, so that the side platform and the side guardrail can be folded in one step, greatly improving the folding efficiency of the cotton picker driving platform.

[0009] Preferably, the lateral platform includes a left platform and a right platform respectively located on both sides of the main frame, and the lateral guardrail includes a left guardrail located on the left side of the left platform and a right guardrail located on the right side of the right platform. Both sides of the main frame are provided with lateral platforms, and the lateral platforms have a large area, which is convenient for working or setting other components on the lateral platforms; both sides of the main frame are provided with lateral platforms, forming an approximately symmetrical structure, which can improve the stability of the main frame setting.

[0010] Preferably, the upper side of the lateral platform is rotatably connected to the upper side of the main frame through a hinge, and when the lateral platform is unfolded, the linear drive device, the first connecting rod and the second connecting rod are all located at the lower side of the lateral platform. The upper side of the lateral platform is a working surface, and the linear drive device, the first connecting rod and the second connecting rod are located at the lower side of the lateral platform to achieve a hidden setting, which will not affect the component setting or personnel operation on the working surface of the lateral platform.

[0011] Preferably, when the linear drive device is retracted to the minimum length, the lateral platform and the lateral guardrail are arranged vertically, and when the linear drive device is extended to the maximum length, the lateral platform and the lateral guardrail are arranged coplanarly. The two extreme positions of the linear drive device correspond to the two states of the lateral platform being unfolded and folded, respectively, so as to facilitate the lateral platform to be folded and unfolded in place.

[0012] Preferably, the lateral platform is detachably connected to an external component, and a detection sensor for detecting whether the external component is removed is provided on the lower side of the lateral platform. When the external component is not removed, if the lateral platform is to be flipped, the detection sensor will alarm and the lateral platform cannot be flipped. Only when the external component is removed, the lateral platform is flipped and the detection sensor will no longer alarm, thereby preventing the linear drive device from ignoring the external component and directly driving the lateral platform and the lateral guardrail to flip, thereby damaging the external component or the driving platform of the cotton picker, and improving the safety of automatic flipping.

[0013] Preferably, the peripheral component includes an extension ladder connected to the rear side of the lateral platform, the bottom surface of the extension ladder is lower than the lower side of the lateral platform so that the detection sensor located at the lower side of the lateral platform can detect the extension ladder. The extension ladder can be reliably detected to ensure that the lateral platform can be folded only after the extension ladder is removed, thereby improving safety.

[0014] Preferably, a mounting support convexly arranged downward is provided on the lower side of the main frame, and one end of the linear drive device is rotatably connected to the mounting support. The mounting support convexly arranges downward from the lower side of the main frame, and the mounting support, the linear drive device and the lateral platform form a reliable triangular support to ensure the stability of the lateral platform when it is flipped and folded.

[0015] Preferably, a plurality of reinforcing members for enhancing the structural strength of the lateral platform are provided on the lower side of the lateral platform. The reinforcing members can improve the structural strength of the lateral platform.

[0016] Preferably, the reinforcement member includes a "C"-shaped groove body with an opening facing downward, the "C"-shaped groove body is arranged along the width direction of the lateral platform, the linear drive device corresponds to the inside of the "C"-shaped groove body, and the first connecting rod corresponds to the inside of the "C"-shaped groove body. The linear drive device and the first connecting rod correspond to the inside of the "C"-shaped groove body, respectively, so that the torque generated by the rotation can be directly borne by the reinforcement member, which is conducive to reducing the influence of the rotation and folding operation on the strength of the lateral platform and improving the structural reliability of the lateral platform.

[0017] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0036] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] like Figures 1 to 10 As shown, one embodiment of the utility model proposes an automatic folding driving platform for a cotton picker, comprising a main frame 1, a lateral platform 2 and a lateral guardrail 21, and the main frame 1 is provided with a lamp frame assembly 101 and a cab assembly 102. The lateral guardrail 21 and the main frame 1 are rotatably connected to the opposite sides of the lateral platform 2, respectively, and the main frame 1 is provided with a linear drive device 22 arranged at an angle to the lateral platform 2, a first connecting rod 23 is rotatably provided on the main frame 1, and a second connecting rod 24 rotatably connected to the first connecting rod 23 is fixedly provided on the lateral guardrail 21, and the linear drive device 22 is rotatably connected to the main frame 1 and the lateral platform 2 so that the linear drive device 22 can drive the lateral platform 2 to rotate relative to the main frame 1 when performing linear extension and retraction, and the lateral platform 2 drives the first connecting rod 23 and the second connecting rod 24 to rotate to realize the synchronous folding or unfolding of the lateral platform 2 and the lateral guardrail 21.

[0038] like Figure 4 and Figure 5As shown, the lateral guardrail 21 and the second connecting rod 24 are fixed and move at the same time, the lateral guardrail 21 is rotationally connected to the lateral platform 2, the first connecting rod 23 is rotationally connected to the second connecting rod 24, the main frame 1 is rotationally connected to the lateral platform 2 and the first connecting rod 23, and the rotation axes of the lateral guardrail 21, the lateral platform 2, the first connecting rod 24 and the second connecting rod 24 are parallel. Therefore, the rotation connection point between the lateral platform 2 and the main frame 1 and the rotation connection point between the lateral guardrail 21 and the lateral platform 2 form a first connection edge 301 determined by the length of the lateral platform 2, the rotation connection point between the lateral platform 2 and the main frame 1 and the rotation connection point between the first connecting rod 23 and the main frame 1 form a second connection edge 302 determined by the length of the main frame 1, and the rotation connection point between the first connecting rod 23 and the main frame 1 and the rotation connection point between the first connecting rod 23 and the second connecting rod 24 form a second connection edge 303 determined by the length of the main frame 1. The third connecting edge 303 is determined by the length of the first connecting rod 23 and the second connecting rod 24, and the connecting line between the connecting points of the lateral guardrail 21 and the lateral platform 2 forms a fourth connecting edge 304 determined by the length of the second connecting rod 24. The first connecting edge 301, the second connecting edge 302, the third connecting edge 303 and the fourth connecting edge 304 form a quadrilateral transmission structure. The first connecting edge 301, the second connecting edge 302, the third connecting edge 303 and the fourth connecting edge 304 are virtual structures, which are shown by double-dotted lines. The position of the second connecting edge 302 remains unchanged relative to the main frame 1. When the linear drive device 22 drives the lateral platform 2 to flip relative to the main frame 1, the first connecting edge 301 is driven to rotate, and the lateral platform 2 moves from Figure 4 The status of Figure 5 When the state changes, the linear drive device 22 extends, and the lateral platform 2, that is, the first connecting edge 301, is driven by the linear drive device 22 to turn clockwise, and the fourth connecting edge 304 rotates together with the first connecting edge 301. Because the third connecting edge 303 restricts the position of the fourth connecting edge 304, the fourth connecting edge 304 rotates counterclockwise while following the rotation of the first connecting edge 301, until the lateral guardrail 21 and the lateral platform 2 are in a vertical state, completing the synchronous folding of the lateral platform 2 and the lateral guardrail 21. On the contrary, the lateral platform 2 is moved from Figure 5 The status of Figure 4 When the state changes, the linear drive device 22 contracts, and the lateral platform 2, that is, the first connecting edge 301, is driven by the linear drive device 22 to flip counterclockwise, and the fourth connecting edge 304 rotates along with the first connecting edge 301. Under the limiting action of the third connecting edge 303, the fourth connecting edge 304 rotates clockwise at the same time, completing the synchronous deployment of the lateral platform 2 and the lateral guardrail 21.

[0039] In this embodiment, the linear drive device 22 is arranged at an angle with the lateral platform 2, so that the linear drive device 22, the lateral platform 2 and the main frame 1 form a triangular support structure. The extension and retraction of the linear drive device 22 will drive the lateral platform 2 to flip, and the triangular support structure can ensure the stability of the position of the lateral platform 2 when it rotates.

[0040] Through the above design scheme, the driving platform can be operated by one person, which improves work efficiency and ensures construction safety. The lateral guardrail 21 and the lateral platform 2 are folded together to reduce the disassembly process. Compared with the traditional mode, there is no need to disassemble, which saves the transfer time, improves the cotton picking efficiency, ensures the safety of the installation process, and can also avoid the loss of parts to ensure the working efficiency of the cotton picker.

[0041] One embodiment of the utility model provides an automatic folding driving platform for a cotton picker, such as Figures 1 to 6 As shown, when the linear drive device 22 is retracted to the minimum length, the lateral platform 2 and the lateral guardrail 21 are arranged vertically, and when the linear drive device 22 is extended to the maximum length, the lateral platform 2 and the lateral guardrail 21 are arranged coplanarly. The two extreme positions of the linear drive device 22 correspond to the two states of the lateral platform 2 being unfolded and folded, respectively, so as to facilitate the lateral platform 2 to be folded and unfolded in place.

[0042] Specifically, Figure 1 and Figure 6 As shown, the linear drive device 22 uses an electric push rod 222. As a simple replacement for the above solution, the linear drive device 22 can also use an oil cylinder. Figure 6 In the figure, the linear drive device 22 includes a cylinder 221 and a push rod 222 that slides along the axis of the cylinder 221 and one end of which is slidably connected to the cylinder 221. The linear drive device 22 is arranged in the width direction of the lateral platform 2. The outer end of the cylinder 221 is rotatably connected to the main frame 1, and the push rod 222 is rotatably connected to the lateral guardrail 21. The lower side of the main frame 1 is provided with a mounting support 223 that is convex downward, and one end of the cylinder 221 away from the push rod 222 is rotatably connected to the mounting support 223. The upper side of the main frame 1 is a working plane. When the lateral platform 2 is unfolded, the upper side of the lateral platform 2 corresponds to the working plane, and the upper side surface of the lateral platform 2 is also used as a working plane. At this time, the lateral guardrail 21 is perpendicular to the upper side surface of the lateral platform 2 and above the upper side surface of the lateral platform 2. The lateral guardrail 21 protects the safe operation of the staff on the lateral platform 2. When the lateral platform 2 is unfolded, the linear drive device 22 is in a retracted state, with a short length, strong rigidity, and reliable support, and can reliably support the lateral platform 2, making it convenient for personnel to work on the lateral platform 2. When the lateral platform 2 is folded, no personnel will work on the lateral platform 2, and peripheral components must also be removed. The overall mass is light, so the linear drive device 22 in an extended state will not affect the stability of the lateral platform 2, and the reliability is high.

[0043] like Figure 5 and Figure 6 As shown, the mounting support 223 includes an L-shaped plate 224 fixed on the main frame 1, and the side facing the right angle of the L-shaped plate 224 is taken as the inner side. The inner side of the L-shaped plate 224 is fitted with the main frame 1 and fixed by bolts. Two parallel mounting support plates 225 are fixedly provided on the outer side of the L-shaped plate 224. The mounting support plates 225 are provided with connecting holes. The mounting support plates 225 are used to rotate the outer end of the connecting cylinder 221 by cooperating with the hinge shaft through the connecting holes. The mounting support plate 225 extends from the L-shaped plate 224 in a direction away from the main frame 1. The outer end of the push rod 222 of the linear drive device 22 is rotatably connected to the lateral platform 2 through a hinge shaft, and the two end positions of the linear drive device 22 respectively correspond to the two ends of the lateral platform 2 in the width direction. As shown Figure 6 It can be seen that a connecting support 25 is provided on the main frame 1, and the connecting support 25 is used to rotatably connect the end of the first connecting rod 23 close to the hinge 4. The shape of the connecting support 25 is similar to the shape of the mounting support 223. The connecting support 25 includes an L-shaped connecting plate 251 bolted to the main frame 1, and a connecting support plate 252 is provided at a right angle outside the connecting plate 251 to hinge the first connecting rod 23.

[0044] One of the embodiments of the utility model provides an automatic folding driving platform for a cotton picker, in which the upper side of the lateral platform 2 is rotatably connected to the upper side of the main frame 1 via a hinge 4. When the lateral platform 2 is unfolded, the linear drive device 22, the first connecting rod 23, and the second connecting rod 24 are all located on the lower side of the lateral platform 2. When the lateral platform 2 is unfolded, the upper side of the lateral platform 2 serves as a working surface, and the linear drive device 22, the first connecting rod 23, and the second connecting rod 24 are hidden on the lower side of the lateral platform 2 to prevent interference with the working surface on the upper side of the lateral platform 2. Figure 3 As shown, the lateral platform 2 is provided with seven hinges 4 at intervals in the length direction thereof, wherein the rotation axes of the seven hinges 4 are arranged in a colinear manner, and two of the seven hinges 4 are respectively arranged at two ends of the lateral platform 2 .

[0045] In order to improve the reliability of the rotation connection between the lateral platform 2 and the lateral guardrail 21, an automatic folding driving platform of a cotton picker is proposed in one embodiment of the utility model. Figure 4 , Figure 7 and Figure 8As shown, the lateral guardrail 21 includes a plurality of connecting sections 213 extending from the upper side of the lateral platform 2 to the lower side of the lateral platform 2, and the connecting sections 213 are provided with spaced first through holes 214 and second through holes 215, and the second connecting rod 24 includes a positioning base plate and positioning side plates 242 oppositely arranged on both sides of the positioning base plate, and the positioning side plates 242 are provided with first mounting holes 243, second mounting holes 244 and third mounting holes 245 arranged in sequence from top to bottom, and the first mounting holes 243 on the two positioning side walls are bridged by a first connecting pin 216, which passes through the first through hole 214, and the first connecting pin 216 is rotatably connected or fixedly connected to the lateral platform 2, and the first connecting pin 216 serves as a common rotation axis of the lateral guardrail 21 and the second connecting rod 24 relative to the lateral platform 2. The second mounting hole 244 and the second through hole 215 are connected with a second connecting pin 217, and the second connecting pin 217 cooperates with the first connecting pin 216 to achieve the relative fixation of the second connecting rod 24 and the lateral guardrail 21. The third mounting hole 245 is located on the side of the line connecting the first mounting hole 243 and the second mounting hole 244 away from the positioning base plate. The third mounting hole 245 is used to hinge the outer end of the first push rod 222. The positioning base plate is provided with a hollow area 240240 at the position corresponding to the third mounting hole 245 to facilitate the second connecting rod 24 to avoid the first connecting rod 23 when rotating.

[0046] One embodiment of the utility model provides an automatic folding driving platform for a cotton picker, such as Figure 1 and Figure 2 As shown, the lateral platform 2 includes a left platform 201 and a right platform 202 respectively located on both sides of the main frame 1, and the lateral guardrail 21 includes a left guardrail 211 located on the left side of the left platform 201 and a right guardrail 212 located on the right side of the right platform 202. The left platform 201 and the left guardrail 211 are driven to flip through the linear drive device 22, the first connecting rod 23 and the second connecting rod 24 correspondingly arranged on the left side of the main frame 1, and the right platform 202 and the right guardrail 212 are driven to flip through the linear drive device 22, the first connecting rod 23 and the second connecting rod 24 correspondingly arranged on the right side of the main frame 1. The left and right directions here are determined according to the main frame 1 facing from back to front, that is, Figure 1 The left platform 201 and the right platform 202 are approximately symmetrical structures, which can provide symmetrical pressure on the main frame 1 and avoid the stability of the main frame 1 being reduced due to the setting of a single-side platform.

[0047] In one embodiment of the present invention, a cotton picker automatic folding driving platform is provided, wherein the lower side of the lateral platform 2 is provided with a plurality of reinforcing members for enhancing the structural strength of the lateral platform. Figure 1 and Figure 6As shown, the reinforcement member includes a "C"-shaped groove body 5 with an opening facing downward, and the "C"-shaped groove body 5 is arranged along the width direction of the lateral platform 2. The reinforcement member also includes a plurality of reinforcing ribs 6 arranged along the length direction of the lateral platform 2, and the reinforcing ribs 6 are fixedly connected to adjacent "C"-shaped groove bodies 5. The linear drive device 22 corresponds to the inside of the "C"-shaped groove body 5, and the first connecting rod 23 corresponds to the inside of the "C"-shaped groove body 5. Figure 6 As shown, the hinge shaft connected to the push rod 222 of the linear drive device 22 for rotationally connecting with the lateral platform 2 is connected to the groove wall of the "C"-shaped groove body 5, and in the "C"-shaped groove body 5 corresponding to the first connecting rod 23 and the second connecting rod 24, two spaced and parallel positioning plates 7 are fixedly provided at one end of the "C"-shaped groove body 5 close to the hinge 4, and the two positioning plates 7 are rotationally connected to the second connecting rod 24 through the hinge shaft. The reinforcement can not only improve the structural strength of the lateral platform 2, but also reduce the deformation degree of the lateral platform 2 when it is turned over, and improve the structural stability of the lateral platform 2 during the turning process. The reinforcement also plays a role in hiding and protecting the linear drive device 22 and the first connecting rod 23.

[0048] One embodiment of the utility model provides an automatic folding driving platform for a cotton picker, wherein the lateral platform 2 is detachably connected to an external component, and a detection sensor for detecting whether the external component is removed is provided on the lower side of the lateral platform 2. Figure 1 and Fig. 9 As shown, the peripheral components include an extension ladder 8 connected to the rear side of the lateral platform 2, and the bottom surface of the extension ladder 8 is lower than the lower side of the lateral platform 2 so that the detection sensor located at the lower side of the lateral platform 2 can detect the extension ladder 8. The side and outer end of the extension ladder 8 are provided with an extension ladder guardrail 81 to improve the safety of the position of the extension ladder 8. The peripheral components also include a fire extinguisher 9 and a front guardrail 11 that are detachably arranged on the lateral platform 2, and the peripheral components also include a logo board 10 that is detachably arranged on the outer side of the lateral platform 2. The detection sensors are divided into an extension ladder detection sensor 12, a fire extinguisher detection sensor 13, a logo board detection sensor 14 and a front guardrail detection sensor 15 according to the working parts. Through holes are provided on the lateral platform 2 at the positions corresponding to the fire extinguisher 9, the logo board 10 and the front guardrail 11 to facilitate the detection sensor to detect whether the fire extinguisher 9, the logo board 10 and the front guardrail 11 are removed and moved away. When the peripheral components are not removed, if the lateral platform 2 is to be flipped, the detection sensor will detect that the peripheral components have not been moved away and will alarm. The alarm here not only refers to alarms in the form of whistles, lights, etc., but can also be a locking signal integrated in the control circuit. When the detection sensor alarms, the lateral platform 2 cannot be flipped. Only after the peripheral components are removed, the detection sensor will no longer alarm when the lateral platform 2 is flipped, thereby avoiding the linear drive device 22 ignoring the peripheral components and directly driving the lateral platform 2 and the lateral guardrail 21 to flip, thereby damaging the peripheral components or the cotton picker driving platform, thereby improving the safety of automatic flipping.

[0049] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
