Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, and specifically to a bagged material lifting and conveying device. Background Technology

[0002] In the logistics and warehousing of bulk materials, bagged materials (such as fertilizers, grains, feed, and chemical raw materials) are an extremely common and abundant form of cargo. They are typically packaged in woven bags, paper bags, or composite bags, offering advantages such as low cost and ease of stacking. However, due to the inherent flexibility of the packaging, the center of gravity of bagged materials changes with the degree of filling.

[0003] Currently, vertical lifting and loading / unloading of bagged materials typically rely on manual labor or semi-mechanized equipment. A common method involves workers or forklifts transporting the bags to a conveyor, which then lifts them to a stacking platform. Workers or forklifts on the stacking platform then relay the bags and manually stack them. This process is not only labor-intensive but also inefficient. Furthermore, as the amount of material increases during stacking, the stacking platform gradually rises. During material processing, it may be necessary to transport multiple materials to stacking platforms of different heights, but the conveyor's lifting height cannot be adjusted accordingly, affecting material transport efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a bagged material lifting and conveying device, and the technical problem to be solved is how to adjust the lifting height to adapt to different conveying heights.

[0005] This invention is achieved through the following technical solution:

[0006] A bagged material lifting and conveying device includes a support frame, on which a feeding mechanism, a discharging mechanism and a lifting mechanism are provided. The feeding mechanism is located at the inlet end of the lifting mechanism, and the discharging mechanism is located at the outlet end of the lifting mechanism.

[0007] The aforementioned lifting mechanism includes a driving wheel, a driven wheel, and a transmission belt, with the driving wheel and driven wheel connected by the transmission belt; a lifting support plate is provided on the transmission belt, which receives bagged materials at the feed end; a sliding groove is provided on the upper surface of the lifting support plate, and a sliding rod is provided in the sliding groove;

[0008] The aforementioned feeding mechanism includes a first material detector, a vertical telescopic device, and an inclined support member. The inclined support member is located at the telescopic end of the vertical telescopic device, and the height of the inclined support member is adjusted by the vertical telescopic device.

[0009] The first material detector is electrically connected to the vertical expansion joint; the first material detector is used to detect the current material stacking height and adjust the extension length of the vertical expansion joint based on the current material stacking height.

[0010] The lower surface of the aforementioned inclined support member is used to contact the slide rod;

[0011] When the aforementioned slide bar contacts the inclined support member and the lifting support plate continues to approach the unloading mechanism, the slide bar slides along the slide groove.

[0012] The support frame provides the structural foundation for the device. The driving and driven wheels are driven by a transmission belt, providing power to the lifting support plate, enabling its cyclical movement and lifting of the bagged material. The lifting support plate receives the bagged material at the feed end and is the material-bearing component. A sliding rod on the upper surface of the lifting support plate slides within a groove, changing the relative position of the material on the lifting support plate and pushing it out. By detecting the material stacking height, the height of the feeding mechanism is adjusted in real time to adapt to gradually increasing stacking heights. Specifically, the height adjustment of the feeding mechanism is achieved by adjusting the extension length of the vertical telescopic device based on the current material stacking height detected by the first material detector. The vertical telescopic device drives the inclined support member to move up and down, changing the height of the inclined support member when in contact with the sliding rod, allowing for dynamic height changes.

[0013] When the lifting support plate reaches the vicinity of the unloading mechanism, the relative position of the material on the lifting support plate is changed through the interaction between the inclined support and the sliding rod. Combined with the vertical expansion joint adjusting the height of the inclined support, flexible adjustment of the material lifting height is achieved to adapt to different conveying heights, solving the problem that the conveyor's lifting height cannot be adjusted according to changes in the stacking platform height, thus affecting material conveying efficiency.

[0014] Furthermore, the aforementioned inclined support member includes an inclined telescopic rod and an inclined support plate, with the inclined support plate disposed on the inclined telescopic rod; the inclined telescopic rod drives the inclined support plate to extend toward the lifting mechanism; when the inclined telescopic rod is in a retracted state, the orthographic projection of the slide rod in the horizontal direction is located beside the inclined support plate; when the inclined telescopic rod is in an extended state, the orthographic projection of the slide rod in the horizontal direction is located on the inclined support plate.

[0015] The fixed end of the aforementioned inclined telescopic rod is connected to the telescopic end of the vertical telescopic device.

[0016] The contact range between the inclined support plate and the slide bar is adjusted by the inclined telescopic rod. The aforementioned inclined telescopic rod drives the inclined support plate to extend or retract towards the lifting mechanism; when the inclined telescopic rod is in the retracted state, the inclined support plate does not contact the slide bar, thus not affecting the normal material lifting of the lifting support plate and avoiding unnecessary interference during the circulation of the lifting support plate.

[0017] During unloading, the inclined telescopic rod extends, bringing the sliding rod into contact with the inclined support plate. This pushes the sliding rod to slide within the chute, ejecting the material from the lifting support plate and changing its position. After unloading, the lifting support plate needs to continue moving. At this point, the inclined telescopic rod retracts, ensuring the inclined support plate is no longer on the transmission path, thus preventing obstruction of the lifting support plate's circulation.

[0018] The aforementioned inclined telescopic rod moves synchronously with the extension and retraction of the vertical telescopic device. While the vertical telescopic device adjusts the height of the inclined support component according to the material stacking height, the inclined telescopic rod can also be adjusted in the tilt direction. The two work together to adjust the material lifting height.

[0019] The aforementioned inclined support plate provides support for the slide rod. When the inclined telescopic rod extends and the slide rod contacts the inclined support plate, the inclined support plate provides a supporting surface for the slide rod. As the lifting support plate continues to approach the unloading mechanism, the slide rod slides along the surface of the inclined support plate, and the chute guides the slide rod to slide along a predetermined trajectory.

[0020] Furthermore, the aforementioned feeding mechanism also includes a feeding roller, which is correspondingly arranged with the inclined support member; the feeding roller receives bagged materials at the discharge end.

[0021] When the aforementioned slide bar contacts the inclined support member and the lifting support plate continues to approach the feeding mechanism, the slide bar slides along the groove to the feeding roller.

[0022] The aforementioned feeding roller receives bagged material at the discharge end. Specifically, during the material lifting process, the slide bar slides along the chute to push the bagged material out of the lifting support plate, allowing the material to reach the discharge end. Then, the feeding roller catches the bagged material that has been pushed out of the lifting support plate. This feeding roller can be connected to a transverse conveying device, reducing manual intervention.

[0023] The feeding rollers are positioned in conjunction with the inclined support components, making the material transfer process smoother after the lifting height is adjusted. When the sliding rod contacts the inclined support component and slides along the chute to the feeding rollers, the feeding rollers can assist the material in transitioning from the lifting support plate to the subsequent conveying stage.

[0024] Furthermore, the aforementioned feeding mechanism includes a feeding roller, which is inclined toward the feeding end.

[0025] The aforementioned feeding rollers utilize the weight of the bagged material itself to cause the bagged material to slide down the inclined feeding rollers towards the feed end.

[0026] Furthermore, the end of the aforementioned slide bar that contacts the inclined support plate is arc-shaped.

[0027] During unloading, the aforementioned sliding rod slides relative to the inclined support plate. By making the end of the sliding rod that contacts the inclined support plate arc-shaped, the contact area between the two is increased. Compared to a sharp or straight end, this reduces the local pressure during contact, lowers the friction between the sliding rod and the inclined support plate, and avoids jamming caused by excessive contact resistance.

[0028] Furthermore, the aforementioned lifting support plate includes a first support plate and a second support plate, wherein the first support plate is connected to the transmission belt;

[0029] The first and second support plates are connected by a fixed rod and a vertical expansion joint, which are arranged along the length of the slide groove. The tilt angle of the second support plate is adjusted by extending or retracting the vertical expansion joint.

[0030] The tilt angle of the second support plate is adjusted by extending and retracting the aforementioned vertical telescopic device, thereby changing the placement posture of the bagged material on the lifting support plate. During unloading, the tilt angle of the second support plate towards the discharge roller is increased, allowing the bagged material to slide more smoothly onto the discharge roller using its own weight.

[0031] Furthermore, the aforementioned feeding mechanism also includes a second material detector, which is electrically connected to the vertical expansion joint;

[0032] The aforementioned second material detector is used to detect whether the lifting support plate is in the discharge zone. When the lifting support plate is in the discharge zone, it sends a discharge signal to the vertical telescopic device. After receiving the discharge signal, the vertical telescopic device adjusts the tilt angle of the second support plate. By increasing the tilt angle of the second support plate towards the discharge roller, the bagged material can be made to slide more smoothly onto the discharge roller using its own weight.

[0033] Furthermore, the aforementioned feeding mechanism also includes a third material detector, which is electrically connected to the vertical expansion joint.

[0034] The aforementioned third material detector is used to detect whether the lifting support plate is in the feeding area. When the lifting support plate is in the feeding area, it sends a feeding signal to the vertical expansion joint. After receiving the feeding signal, the tilt angle of the second support plate is reset.

[0035] Reduce the tilt angle of the second support plate towards the upward material roller to prepare the second support plate for receiving bagged materials and prevent the bagged materials from slipping off the second support plate during the lifting process.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0037] The driving and driven wheels are driven by a transmission belt, providing power to the lifting support plate, enabling its cyclical movement and lifting of the bagged material. The lifting support plate receives the bagged material at the feed end, serving as the material-bearing component. A sliding rod on the upper surface of the lifting support plate slides within a groove, changing the relative position of the material on the lifting support plate and pushing it out. By detecting the material stacking height, the height of the feeding mechanism is adjusted, achieving real-time adjustment of the lifting height to adapt to gradually increasing stacking heights. Specifically, the height adjustment of the feeding mechanism is achieved by adjusting the extension length of the vertical telescopic joint based on the current material stacking height detected by the first material detector. The vertical telescopic joint drives the inclined support member to move up and down, changing the height of the inclined support member when in contact with the sliding rod, allowing for dynamic height changes.

[0038] When the lifting support plate reaches the vicinity of the unloading mechanism, the relative position of the material on the lifting support plate is changed through the interaction between the inclined support and the sliding rod. Combined with the vertical expansion joint adjusting the height of the inclined support, flexible adjustment of the material lifting height is achieved to adapt to different conveying heights, solving the problem that the conveyor's lifting height cannot be adjusted according to changes in the stacking platform height, thus affecting material conveying efficiency.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0045] First embodiment:

[0046] A bagged material lifting and conveying device includes a support frame 1, on which a feeding mechanism 3, a discharging mechanism 4, and a lifting mechanism 2 are mounted. Figure 1 The aforementioned feeding mechanism 3 is located at the feeding end of the lifting mechanism 2, and the aforementioned unloading mechanism 4 is located at the discharging end of the lifting mechanism 2.

[0047] The aforementioned lifting mechanism 2 includes a driving wheel 21, a driven wheel 22, and a transmission belt 23. The driving wheel 21 and the driven wheel 22 are connected by the transmission belt 23. A lifting support plate 24 is provided on the transmission belt 23, which receives bagged materials at the feeding end. A groove 243 is provided on the upper surface of the lifting support plate 24, and a sliding rod 244 is provided in the groove 243. One end of the sliding rod 244 is arc-shaped.

[0048] The aforementioned feeding mechanism 4 includes a first material detector, a vertical telescopic device 43, and an inclined support 41, combined with... Figure 2 The aforementioned inclined support 41 is installed at the telescopic end of the vertical telescopic member 43, and the height of the inclined support 41 is adjusted by the vertical telescopic member 43. The aforementioned first material detector can be a laser sensor and a controller, and the vertical telescopic member 43 can be a cylinder, hydraulic cylinder, etc. The laser sensor, the vertical telescopic member 43 and the controller are electrically connected, and the controller can be a microcontroller, PLC, etc. When the aforementioned laser sensor detects the current material stacking height, it transmits the current material stacking height to the controller, and the controller generates a control command based on the current material stacking height to control the extension length of the vertical telescopic member 43.

[0049] The lower surface of the aforementioned inclined support member 41 is used to contact the slide rod 244, and the end of the slide rod 244 that contacts the inclined support plate 412 is arc-shaped. During unloading, the slide rod 244 and the inclined support plate 412 slide relative to each other. This arc shape increases the contact area between the slide rod 244 and the inclined support member 41, reducing local pressure during contact compared to a sharp or straight end, lowering the friction between the slide rod 244 and the inclined support plate 412, and avoiding jamming caused by excessive contact resistance.

[0050] When the slide rod 244 contacts the inclined support member 41 and the lifting support plate 24 continues to approach the unloading mechanism 4, the slide rod 244 slides along the slide groove 243. A first spring 247 is provided in the slide groove 243. The first spring 247 abuts against the slide rod 244 to reset the slide rod 244.

[0051] The support frame 1 provides the structural foundation for the device. The driving wheel 21 and driven wheel 22 are driven by the transmission belt 23, providing power to the lifting support plate 24, enabling the lifting support plate 24 to circulate and lift the bagged material. The lifting support plate 24 receives the bagged material at the feeding end and is the material-bearing component. The sliding rod 244 on the upper surface of the lifting support plate 24 slides in the sliding groove 243, changing the relative position of the material on the lifting support plate 24 and pushing the material out of the lifting support plate 24. By detecting the material stacking height, the height of the feeding mechanism 4 is adjusted to achieve real-time adjustment of the lifting height to adapt to the gradually increasing stacking height. The specific method of adjusting the height of the feeding mechanism 4 is as follows: the extension length of the vertical telescopic device 43 is adjusted according to the current material stacking height detected by the first material detector. The vertical telescopic device 43 drives the inclined support member 41 to move up and down, changing the height of the inclined support member 41 and the sliding rod 244 when in contact, so that the height can be dynamically changed.

[0052] When the lifting support plate 24 reaches the vicinity of the unloading mechanism 4, the relative position of the material on the lifting support plate 24 is changed through the interaction between the inclined support member 41 and the slide rod 244. Combined with the adjustment of the height of the inclined support member 41 by the vertical expansion joint 43, the lifting height of the material is flexibly adjusted to adapt to different conveying heights, thus solving the problem that the lifting height of the conveyor cannot be adjusted with the change of the stacking platform height, which affects the material conveying efficiency.

[0053] Second embodiment:

[0054] Based on the first embodiment, the inclined support member 41 includes an inclined telescopic rod 411 and an inclined support plate 412. The inclined support plate 412 is disposed on the inclined telescopic rod 411. The inclined telescopic rod 411 can be a cylinder, hydraulic cylinder, etc. The inclined telescopic rod 411 drives the inclined support plate 412 to extend toward the lifting mechanism 2. When the inclined telescopic rod 411 is in the retracted state, the orthographic projection of the slide rod 244 in the horizontal direction is located beside the inclined support plate 412. When the inclined telescopic rod 411 is in the extended state, the orthographic projection of the slide rod 244 in the horizontal direction is located on the inclined support plate 412.

[0055] The fixed end of the aforementioned oblique telescopic rod 411 is connected to the telescopic end of the vertical telescopic device 43.

[0056] The contact range between the inclined support plate 412 and the slide rod 244 is adjusted by the inclined telescopic rod 411. The inclined telescopic rod 411 drives the inclined support plate 412 to extend or retract towards the lifting mechanism 2. When the inclined telescopic rod 411 is in the retracted state, the inclined support plate 412 does not contact the slide rod 244, which does not affect the normal material lifting of the lifting support plate 24 and avoids unnecessary interference during the circulation of the lifting support plate 24.

[0057] During unloading, the inclined telescopic rod 411 extends, causing the slide rod 244 to contact the inclined support plate 412, pushing the slide rod 244 to slide within the slide groove 243, thus pushing the material out of the lifting support plate 24 and changing the material's position. After unloading is completed, the lifting support plate 24 needs to continue moving. At this time, the inclined telescopic rod 411 retracts, so that the inclined support plate 412 is no longer located on the transmission path, avoiding obstruction of the circulation of the lifting support plate 24.

[0058] The aforementioned inclined telescopic rod 411 moves synchronously with the extension and retraction of the vertical telescopic device 43. During the process of the vertical telescopic device 43 adjusting the height of the inclined support 41 according to the material stacking height, the inclined telescopic rod 411 can be adjusted in the tilt direction based on this, and the two work together to achieve the adjustment of the material lifting height.

[0059] The aforementioned inclined support plate 412 provides support for the slide rod 244. When the inclined telescopic rod 411 extends and causes the slide rod 244 to contact the inclined support plate 412, the inclined support plate 412 provides a support surface for the slide rod 244. As the lifting support plate 24 continues to approach the feeding mechanism 4, the slide rod 244 slides along the surface of the inclined support plate 412, and the slide groove 243 guides the slide rod 244 to slide along a predetermined trajectory.

[0060] Third embodiment:

[0061] Based on the second embodiment, the above-mentioned feeding mechanism 4 also includes a feeding roller 42, which is correspondingly arranged with the inclined support member 41; the feeding roller 42 receives bagged materials at the discharge end.

[0062] When the slide bar 244 contacts the inclined support member 41 and the lifting support plate 24 continues to approach the feeding mechanism 4, the slide bar 244 slides along the sliding groove 243 to the feeding roller 42.

[0063] The aforementioned feeding roller 42 receives bagged material at the discharge end. Specifically, during the material lifting process, the slide bar 244 slides along the slide groove 243 to push the bagged material out of the lifting support plate 24, allowing the material to reach the discharge end. Then, the feeding roller 42 catches the bagged material pushed out of the lifting support plate 24. This feeding roller 42 can be connected to a transverse conveying device, reducing manual intervention.

[0064] The feeding roller 42 is correspondingly arranged with the inclined support 41, making the material transfer process smoother after the lifting height is adjusted. When the slide bar 244 contacts the inclined support 41 and slides along the slide groove 243 to the feeding roller 42, the feeding roller 42 can assist the material to transition from the lifting support plate 24 to the subsequent conveying stage.

[0065] Fourth embodiment:

[0066] Based on any of the above embodiments, the feeding mechanism 3 includes a feeding roller, which is inclined toward the feeding end.

[0067] The aforementioned feeding rollers utilize the weight of the bagged material itself to cause the bagged material to slide down the inclined feeding rollers towards the feed end.

[0068] Fifth embodiment:

[0069] Based on any of the above embodiments, the lifting support plate 24 includes a first support plate 241 and a second support plate 242, wherein the first support plate 241 is connected to the transmission belt 23.

[0070] The first support plate 241 and the second support plate 242 are connected by a fixing rod 245 and a vertical expansion joint 246. The fixing rod 245 and the vertical expansion joint 246 are arranged along the length of the slide groove 243. The tilt angle of the second support plate 242 is adjusted by the extension and retraction of the vertical expansion joint 246.

[0071] The tilt angle of the second support plate 242 is adjusted by extending and retracting the vertical telescopic device 246, thereby changing the placement posture of the bagged material on the lifting support plate 24. During unloading, the tilt angle of the second support plate 242 towards the discharge roller 42 is increased, allowing the bagged material to slide more smoothly onto the discharge roller 42 using its own weight.

[0072] A second spring 248 may also be fitted onto the aforementioned fixed rod 245 and vertical telescopic device 246. The second spring 248 is used for buffering and to improve the stability of bagged materials during loading and unloading.

[0073] In a specific embodiment, the feeding mechanism 4 further includes a second material detector, which is electrically connected to the vertical telescopic device 246. The second material detector can be a photoelectric sensor, and the vertical telescopic device 246 can be a cylinder, hydraulic cylinder, etc. The photoelectric sensor and the vertical telescopic device 246 are connected to a controller. The photoelectric sensor is set in the discharge area. When the photoelectric sensor detects that the lifting support plate 24 has entered the discharge area, the controller sends a discharge signal to the vertical telescopic device 246. After receiving the discharge signal, the vertical telescopic device 246 increases the tilt angle of the second support plate 242 towards the discharge roller 42, so that the bagged material can slide more smoothly to the discharge roller 42 by utilizing its own weight.

[0074] In a specific embodiment, the feeding mechanism 3 further includes a third material detector, which is electrically connected to the vertical telescopic device 246. The third material detector can be a photoelectric sensor, which is connected to the controller. The photoelectric sensor is located in the feeding area. When the photoelectric sensor detects that the lifting support plate 24 has entered the feeding area, the controller sends a feeding signal to the vertical telescopic device 246. After receiving the feeding signal, the vertical telescopic device 246 reduces the tilt angle of the second support plate 242 towards the upward feeding roller, thereby resetting the tilt angle of the second support plate 242. This prepares the second support plate 242 to receive the bagged material and prevents the bagged material from slipping off the second support plate 242 during the lifting process.

[0075] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
