Description

Technical Field

[0001] This application belongs to the technical field of feeding equipment, specifically relating to a movable screw feeder. Background Technology

[0002] A screw feeder is a continuous feeding device that uses the rotation of a screw blade to push materials. It is widely used in industries such as chemical, metallurgy, building materials, and mining, and is mainly used for conveying powdery, granular, and small block materials.

[0003] Currently, screw feeders typically include a frame, a conveying assembly, and a drive assembly. The conveying assembly includes a conveying cylinder mounted on the frame, a conveying shaft inside the conveying cylinder, and helical blades surrounding the conveying shaft. A feed inlet is located at the top of one end of the conveying cylinder, and a discharge outlet is located at the bottom of the other end. The drive assembly includes a drive motor and a reducer whose input end is connected to the output shaft of the drive motor. The output end of the reducer is connected to the conveying shaft, allowing the drive motor to drive the conveying shaft via the reducer. This, in turn, causes the conveying shaft to rotate the helical blades, thereby... The spiral blades push the material inside the conveying cylinder, ultimately pushing it to the discharge port where it falls. Since the conveying cylinder is mounted on the frame, the frame can support it. However, in cases where the foundation is uneven, some of the frame's legs may not be in contact with the ground, causing the frame to sway up and down, thus affecting the stability of the screw feeder. In addition, moving the screw feeder requires manual handling or the use of a crane, which affects the ease of moving the screw feeder. Utility Model Content

[0004] This application provides a movable screw feeder to enable the screw feeder to adapt to working conditions with poor foundations, increase the stability of the screw feeder, and facilitate the movement of the screw feeder.

[0005] The technical solution adopted in this application is as follows:

[0006] A movable screw feeder includes:

[0007] A conveying assembly, comprising a conveying cylinder, a conveying shaft disposed inside the conveying cylinder, and helical blades disposed on the outer periphery of the conveying shaft;

[0008] A drive assembly, which is drively connected to the conveyor shaft and is used to drive the conveyor shaft to rotate;

[0009] The support assembly includes a first support leg fixedly connected to the conveying cylinder and a second support leg hinged to the conveying cylinder. The second support leg is spaced apart from the first support leg, and both the first support leg and the second support leg are provided with mechanical slippers at their bottoms.

[0010] By adopting the above technical solution, when using the movable screw feeder in this application, the drive assembly is started, which in turn drives the conveyor shaft, so that the conveyor shaft drives the screw blades to rotate, thereby pushing the material in the conveyor cylinder to achieve feeding and conveying of the material.

[0011] Since the first support leg is fixedly connected to the conveying cylinder and the second support leg is hinged to the conveying cylinder, the first and second support legs can jointly support the conveying assembly. Furthermore, when the movable screw feeder is installed on an uneven ground, the angle of the second support leg can be adjusted so that both the first and second support legs can contact the ground. This avoids situations where some legs cannot contact the ground, which could cause the movable screw feeder to sway up and down, thereby increasing the stability of the movable screw conveyor.

[0012] Meanwhile, when the movable screw feeder of this application is installed on the ground, the first support leg can play the role of positioning the movable screw feeder. Then, the second support leg is adjusted according to its position so that it can touch the ground. The first and second support legs can jointly support the conveying component. Compared with the prior art where multiple support legs are hinged to the conveying cylinder, the technical solution of this application eliminates the component for locking the support legs, thereby reducing the manufacturing cost of the movable screw feeder.

[0013] Because the bottoms of the first and second support legs are equipped with mechanical slippers, on the one hand, both the first and second support legs contact the ground through their respective mechanical slippers, increasing the contact area between the first and second support legs and the ground. This reduces the pressure between the first and second support legs and the ground, significantly lowering the risk of the first and second support legs sinking into the ground, and further increasing the stability of the movable screw feeder. On the other hand, when moving the movable screw feeder, only pushing the device is needed to allow the mechanical slippers to slide relative to the ground, reducing the moving efficiency and difficulty of the device and improving its ease of movement. Furthermore, the mechanical slippers at the bottom of the second support leg also increase its adjustability, further reducing the impact of uneven ground on the stability of the movable screw feeder.

[0014] Optionally, the conveying cylinder has a conveying start end and a conveying end opposite to the conveying start end. The top of the conveying start end is provided with a feed inlet, and the bottom of the conveying end end is provided with a discharge outlet. The first support leg is located at the conveying start end, and the second support leg is located between the conveying start end and the conveying end end.

[0015] By adopting the above technical solution, when using the movable screw feeder, materials are continuously poured into the feed inlet, and the materials accumulate at the feed inlet, which results in greater pressure on the beginning of the conveying cylinder. In this application, by placing the first support leg at the beginning of the conveying, the conveying cylinder can be mainly supported by the first support leg to increase the stability of the movable screw feeder. Furthermore, by placing the second support leg between the beginning and end of the conveying, the second support leg can avoid the discharge port to ensure the feeding speed of the movable screw feeder.

[0016] Optionally, the first support leg includes a connecting seat and a first leg. The connecting seat includes connecting bodies located on both sides of the conveying cylinder and a connecting plate connecting the two connecting bodies. The first leg is located at the bottom of the connecting plate.

[0017] By adopting the above technical solution, since the connecting seat includes connecting bodies located on both sides of the conveying cylinder and a connecting plate connecting the two connecting bodies, compared with the solution of directly fixing the first leg to the conveying cylinder, the connection point between the first support leg and the conveying cylinder is increased, thereby increasing the connection stability between the first support leg and the conveying cylinder, and further ensuring the stability of the movable screw feeder.

[0018] Optionally, the second support leg includes a hinged seat and a second leg. The hinged seat includes wing plates located on both sides of the conveying cylinder and a seat plate connected to the two wing plates. The wing plates are hinged to the conveying cylinder, and the second leg is located at the bottom of the seat plate.

[0019] By adopting the above technical solution, since the hinged seat includes wing plates located on both sides of the conveying cylinder and a seat plate connected to the two wing plates, the distance between the two wing plates is increased compared to the solution of directly hinged to the bottom of the conveying cylinder. This increases the support stability of the second support leg on the conveying assembly, thereby further ensuring the stability of the movable screw feeder.

[0020] Optionally, a reinforcing beam is provided at the bottom of the seat plate. The reinforcing beam is inclined, and the end of the reinforcing beam away from the seat plate is connected to the second leg. The top view projection of the hinge position of the wing plate and the conveying cylinder is located between the connection position of the reinforcing beam and the seat plate and the connection position of the second leg and the seat plate.

[0021] By adopting the above technical solution, since a reinforcing beam is provided at the bottom of the seat plate, the reinforcing beam is inclined, and the end of the reinforcing beam away from the seat plate is connected to the second leg, the reinforcing beam, the seat plate, and the second leg together form a triangle, thereby increasing the connection stability between the second leg and the seat plate. Furthermore, since the top view projection of the hinge position between the wing plate and the conveyor cylinder is located between the connection position of the reinforcing beam and the seat plate and the connection position of the second leg and the seat plate, the hinge position between the second support leg and the conveyor cylinder is located on the side of the second support leg, thereby reducing the pressure borne by the second support leg to a certain extent, reducing the risk of sinking to the ground due to the large pressure borne by the second support leg, and further increasing the stability of the movable screw feeder.

[0022] Optionally, the conveying cylinder is inclined, and the conveying shaft has a first end at a relatively lower position and a second end at a relatively higher position. The two ends of the conveying cylinder are respectively provided with a first support sleeve and a second support sleeve corresponding to the first end and the second end. The first end is provided with a first shaft head extending out of the first support sleeve, and the second end is provided with a second shaft head extending out of the second support sleeve. A tapered bearing sleeved on the first shaft head is provided inside the first support sleeve, and a self-aligning bearing sleeved on the second shaft head is provided inside the second support sleeve.

[0023] By adopting the above technical solution, since the first support sleeve is equipped with a tapered bearing sleeved on the first shaft head, and the second support sleeve is equipped with a self-aligning bearing sleeved on the second shaft head, the tapered bearing located at a relatively lower position on the conveying cylinder can mainly bear the axial load of the conveying shaft, and the self-aligning bearing located at a relatively higher position can mainly bear the radial load of the conveying shaft. This improves the ability of the conveying shaft to resist the impact load generated by the instantaneous material jamming and increases the stability of the conveying shaft, thereby increasing the stability of the movable screw feeder and reducing the failure rate of the movable screw feeder.

[0024] Optionally, the two ends of the conveying cylinder are respectively provided with support members, and the first support sleeve and the second support sleeve are respectively fixedly connected to the two support members.

[0025] By adopting the above technical solution, since the first support sleeve and the second support sleeve are fixedly connected to the two support members respectively, the stability of the first support sleeve and the second support sleeve is increased, which in turn further increases the stability of the conveyor shaft.

[0026] Optionally, the drive assembly includes a drive motor, the output shaft of which is connected to the first shaft head, a support beam is provided on the side of the first support leg, the support beam is connected to a mechanical slipper provided on the first support leg, and support frames connected to the support beam are provided on both sides of the drive motor.

[0027] By adopting the above technical solution, since support frames connected to the support beams are provided on both sides of the drive motor, and the support beams are connected to the mechanical slippers located on the first support leg, the drive motor can be supported by the first support leg to increase the stability of the drive motor. At the same time, it avoids the need to set up separate support components to support the drive motor, thereby reducing the production cost of the movable screw feeder. Meanwhile, since the output shaft of the drive motor is connected to the first shaft head, the drive motor is located at the lower end of the conveying cylinder, thereby reducing the overall height of the movable screw feeder and realizing the miniaturization design of the movable screw feeder. It also lowers the center of gravity of the movable screw feeder to reduce the vibration amplitude of the movable screw feeder, thereby ensuring the stable operation of the movable screw feeder.

[0028] Optionally, both ends of the first support sleeve are provided with a first sealing plate sleeved on the first shaft head, and the first support sleeve is provided with an oil injection nozzle;

[0029] And / or, one end of the second support sleeve is provided with a second sealing plate sleeved on the second shaft head, the other end of the second support sleeve is provided with a sealing cap, and the second support sleeve is provided with an oil injection nozzle.

[0030] By adopting the above technical solution, since both ends of the first support sleeve are provided with first sealing plates fitted onto the first shaft head, the first sealing plates can be used to seal the first support sleeve, thereby improving the dustproof effect on the tapered bearing and extending the service life of the tapered bearing; in addition, the first support sleeve is provided with an oil injection nozzle, so that grease can be added to the first support sleeve through the oil injection nozzle, thereby extending the service life of the tapered bearing.

[0031] Because one end of the second support sleeve is provided with a second sealing plate fitted onto the second shaft head, and the other end of the second support sleeve is provided with a sealing cap, the second support sleeve can be sealed by the second sealing plate and the sealing cap, thereby improving the dustproof effect on the self-aligning bearing and extending the service life of the self-aligning bearing; in addition, the second support sleeve is provided with an oil injection nozzle, so that grease can be added to the second support sleeve through the oil injection nozzle, thereby extending the service life of the self-aligning bearing.

[0032] Optionally, the side of the conveying cylinder is provided with at least one inspection port and an inspection door that can close and open the inspection port. The top end of the inspection door is hinged to the conveying cylinder, and the inspection door is provided with a locking member for locking the inspection door.

[0033] And / or, the mechanical skid includes a base plate, a top plate spaced apart from the base plate, and a guide tube disposed between the base plate and the top plate, at least a portion of the guide tube protruding outside the base plate and the top plate;

[0034] And / or, the mechanical skid includes a base plate and a reinforcing plate, the base plate having a straight section and curved sections located at both ends of the straight section, the reinforcing plate being located inside the curved sections and connected to the curved sections and the straight section.

[0035] By adopting the above technical solution, when inspecting the conveying assembly or when material is stuck inside the conveying cylinder, the locking device is operated to unlock the inspection door. Then, the inspection door is flipped upwards to open the inspection port, allowing for easy inspection of the conveying assembly or removal of stuck material. This facilitates both the maintenance of the conveying assembly and the removal of stuck material. Furthermore, since the top end of the inspection door is hinged to the conveying cylinder, compared to a design where the bottom of the inspection door is hinged, it avoids interference with personnel and reduces the difficulty of inspecting the conveying assembly. Moreover, closing the inspection port only requires applying an initial downward force to close it using the door's own weight. This also reduces the difficulty of locking the inspection door compared to a design where the door is flipped downwards.

[0036] Because a guide tube is provided between the top plate and the bottom plate, with at least a portion of the guide tube protruding from the outside of the bottom plate and the top plate, on the one hand, when moving the movable screw feeder, the guide tube can also be used to guide the movable screw feeder, thereby reducing the occurrence of mechanical slippers getting stuck on the ground, thus further reducing the difficulty of moving the movable screw feeder and further improving the convenience of moving the movable screw feeder. On the other hand, it increases the structural strength of the mechanical slippers, thereby increasing the stability of the movable screw feeder.

[0037] Because the base plate has a straight section and curved sections at both ends of the straight section, the curved sections can guide the movable screw feeder when it is moved, reducing the occurrence of the mechanical slipper getting stuck on the ground. This further reduces the difficulty of moving the movable screw feeder and improves the ease of movement. Furthermore, because the reinforcing plate is located inside the curved section and connects the curved section and the straight section, the structural strength of the base plate is increased, thereby increasing the stability of the movable screw feeder and reducing the manufacturing cost of the mechanical slipper.

[0038] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0039] 1. The movable screw feeder of this application includes a conveying assembly, a driving assembly, and a supporting assembly. The conveying assembly includes a conveying cylinder, a conveying shaft disposed inside the conveying cylinder, and helical blades disposed on the outer periphery of the conveying shaft. The driving assembly is tractively connected to the conveying shaft and is used to drive the conveying shaft to rotate. The supporting assembly includes a first supporting leg fixedly connected to the conveying cylinder and a second supporting leg hinged to the conveying cylinder. The second supporting leg is spaced apart from the first supporting leg, and mechanical slippers are provided at the bottom of both the first and second supporting legs. This allows the movable screw feeder to be moved simply by pushing it, thereby improving the convenience of moving the movable screw feeder. At the same time, by adjusting the second supporting leg, both the first and second supporting legs can be made to contact the ground, thus ensuring the stability of the movable screw feeder.

[0040] 2. The conveying cylinder in this application has a conveying start end and a conveying end end opposite to the conveying start end. The top of the conveying start end is provided with a feed inlet, and the bottom of the conveying end end is provided with a discharge outlet. The first support leg is located at the conveying start end, and the second support leg is located between the conveying start end and the conveying end end. When using the movable screw feeder, materials are continuously poured into the feed inlet, and the materials accumulate at the feed inlet, which makes the conveying start end of the conveying cylinder subject to greater pressure. In this application, by setting the first support leg at the conveying start end, the conveying cylinder can be mainly supported by the first support leg to increase the stability of the movable screw feeder. Furthermore, by setting the second support leg between the conveying start end and the conveying end end, the second support leg can avoid the discharge outlet to ensure the feeding speed of the movable screw feeder.

[0041] 3. The drive assembly in this application includes a drive motor, the output shaft of which is driven and connected to a first shaft head. A support beam is provided on the side of the first support leg, and the support beam is connected to a mechanical slipper provided on the first support leg. Support frames connected to the support beam are provided on both sides of the drive motor, thereby enabling the first support leg to support the drive motor, increasing the stability of the drive motor, and avoiding the need for separate support components to support the drive motor, thus reducing the production cost of the movable screw feeder. At the same time, since the output shaft of the drive motor is driven and connected to the first shaft head, the drive motor is located at the lower end of the conveying cylinder, thereby reducing the overall height of the movable screw feeder, realizing the miniaturization design of the movable screw feeder, and lowering the center of gravity of the movable screw feeder to reduce the vibration amplitude of the movable screw feeder, thereby ensuring the stable operation of the movable screw feeder.

[0053] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0056] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0057] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0058] Reference Figures 1 to 8 A movable screw feeder is disclosed, comprising a conveying assembly 1, a driving assembly, and a supporting assembly. The conveying assembly 1 includes a conveying cylinder 11, a conveying shaft 12 disposed inside the conveying cylinder 11, and a screw blade 13 disposed on the outer periphery of the conveying shaft 12. The driving assembly is tractively connected to the conveying shaft 12 and is used to drive the conveying shaft 12 to rotate. The supporting assembly includes a first supporting leg 3 fixedly connected to the conveying cylinder 11 and a second supporting leg 4 hinged to the conveying cylinder 11. The second supporting leg 4 is spaced apart from the first supporting leg 3, and mechanical slippers 5 are provided at the bottom of both the first supporting leg 3 and the second supporting leg 4.

[0059] When using the movable screw feeder of this application, the drive assembly is started, which in turn drives the conveyor shaft 12 to rotate the screw blades 13, thereby pushing the material in the conveyor cylinder 11 to achieve feeding and conveying of the material.

[0060] Since the first support leg 3 is fixedly connected to the conveying cylinder 11 and the second support leg 4 is hinged to the conveying cylinder 11, the first support leg 3 and the second support leg 4 can jointly support the conveying assembly 1. On the other hand, when the movable screw feeder is installed on an uneven ground, the angle of the second support leg 4 can be adjusted so that both the first support leg 3 and the second support leg 4 can contact the ground. This avoids the situation where some legs cannot contact the ground, which may cause the movable screw feeder to sway up and down, thereby increasing the stability of the movable screw conveyor.

[0061] Meanwhile, when the movable screw feeder of this application is installed on the ground, the first support leg 3 can play the role of positioning the movable screw feeder. Then, the second support leg 4 is adjusted according to its position so that the second support leg 4 can touch the ground, so that the first support leg 3 and the second support leg 4 can jointly support the conveying component 1. Compared with the prior art where multiple support legs are hinged to the conveying cylinder 11, the technical solution of this application eliminates the component for locking the support legs, thereby reducing the manufacturing cost of the movable screw feeder.

[0062] Since both the bottom of the first support leg 3 and the second support leg 4 are equipped with mechanical slippers 5, on the one hand, the first support leg 3 and the second support leg 4 are in contact with the ground through their respective mechanical slippers 5, thereby increasing the contact area between the first support leg 3 and the ground and reducing the pressure between the first support leg 3 and the ground and the second support leg 4, thus greatly reducing the risk of the first support leg 3 and the second support leg 4 sinking into the ground, and further increasing the stability of the movable screw feeder. On the other hand, when moving the movable screw feeder, it is only necessary to push the movable screw feeder to make the mechanical slippers 5 slide relative to the ground, thereby reducing the moving efficiency and difficulty of the movable screw feeder and improving the convenience of moving the movable screw feeder. Furthermore, by setting the mechanical slippers 5 at the bottom of the second support leg 4, the adjustable range of the second support leg 4 can also be increased, thereby further reducing the impact of uneven ground on the stability of the movable screw feeder.

[0063] This application does not specify the exact location of the first support leg 3 and the second support leg 4, but refers to... Figure 1Preferably, the conveying cylinder 11 has a conveying start end and a conveying end end opposite to the conveying start end. The top of the conveying start end is provided with a feed inlet 112, and the bottom of the conveying end end is provided with a discharge outlet 111. The first support leg 3 is located at the conveying start end, and the second support leg 4 is located between the conveying start end and the conveying end end.

[0064] It is understandable that one end of the conveying cylinder 11 constitutes the conveying start end, and the other end of the conveying cylinder 11 constitutes the conveying end end. The first support leg 3 is located at the conveying start end and at the bottom of the conveying cylinder 11, and the second support leg 4 is located in the middle of the conveying cylinder 11 and at the bottom of the conveying cylinder 11.

[0065] When using the movable screw feeder, materials are continuously poured into the feed inlet 112, and the materials accumulate at the feed inlet 112, which causes the pressure on the beginning of the conveying cylinder 11 to be relatively large. In this application, by setting the first support leg 3 at the beginning of the conveying, the first support leg 3 can be mainly used to support the conveying cylinder 11, thereby increasing the stability of the movable screw feeder. In addition, by setting the second support leg 4 between the beginning and end of the conveying, the second support leg 4 can avoid the discharge port 111, thereby ensuring the feeding speed of the movable screw feeder.

[0066] In other embodiments, the first support leg 3 and the second support leg 4 may be positioned in other locations, for example, the first support leg 3 may be positioned at a non-end of the conveying cylinder 11 and the second support leg 4 may be positioned at the end of the conveying process.

[0067] This application does not specifically limit the structure of the first supporting leg 3; preferably, refer to... Figure 1 and Figure 5 The first support leg 3 includes a connecting seat 31 and a first support leg 32. The connecting seat 31 includes a connecting body 311 located on both sides of the conveying cylinder 11 and a connecting plate 312 connecting the two connecting bodies 311. The first support leg 32 is located at the bottom of the connecting plate 312.

[0068] It is understandable that there are two connecting bodies 311, which are fixedly connected to both sides of the conveying cylinder 11 respectively. The two ends of the connecting plate 312 are fixedly connected to the two connecting bodies 311 respectively and are located at the bottom of the conveying cylinder 11.

[0069] Since the connecting seat 31 includes connecting bodies 311 located on both sides of the conveying cylinder 11 and connecting plate 312 connecting the two connecting bodies 311, compared with the solution of directly fixing the first leg 32 to the conveying cylinder 11, the connection point between the first support leg 3 and the conveying cylinder 11 is increased, so as to increase the connection stability between the first support leg 3 and the conveying cylinder 11, and further ensure the stability of the movable screw feeder.

[0070] Preferably, there are two first legs 32 corresponding to the connecting body 311. Both first legs 32 are fixedly connected to the bottom of the connecting plate 312 and located directly below their respective connecting bodies 311, so as to further increase the support stability of the first support leg 3 on the conveying component 1.

[0071] This application does not specify a particular method for fixing the first leg 32 to the connecting plate 312. Preferably, the top of the first leg 32 is provided with a plate, which is fixedly connected to the connecting plate 312 by bolts to achieve a fixed connection between the first leg 32 and the connecting plate 312. In other embodiments, the first leg 32 can also be fixedly connected to the connecting plate 312 by welding.

[0072] This application does not impose specific limitations on the structure of the connector 311. Preferably, the connector 311 is a box-shaped structure assembled from plates, so as to reduce the weight of the connector 311 while ensuring its structural strength. In other embodiments, the connector 311 may also be a block structure.

[0073] In other embodiments, the first support leg 3 may also be an H-shaped frame structure disposed on the conveying cylinder 11.

[0074] This application does not specifically limit the structure of the second support leg 4; preferably, refer to... Figure 1 , Figure 7 and Figure 8 The second support leg 4 includes a hinge seat 41 and a second support leg 42. The hinge seat 41 includes wing plates 411 located on both sides of the conveying cylinder 11 and a seat plate 412 connected to the two wing plates 411. The wing plates 411 are hinged to the conveying cylinder 11, and the second support leg 42 is located at the bottom of the seat plate 412.

[0075] It is understandable that there are two wing plates 411, which are located on both sides of the conveying cylinder 11 and hinged to the conveying cylinder 11. Both wing plates 411 are fixedly connected to the base plate 412.

[0076] Since the hinge seat 41 includes wing plates 411 located on both sides of the conveying cylinder 11 and a seat plate 412 connected to the two wing plates 411, the distance between the two wing plates 411 is increased compared to the scheme of directly hinged to the bottom of the conveying cylinder 11. This increases the support stability of the second support leg 4 on the conveying assembly 1, thereby further ensuring the stability of the movable screw feeder.

[0077] This application does not specifically limit the hinge method between the wing plate 411 and the conveying cylinder 11. Preferably, hinge shafts are provided on both sides of the conveying cylinder 11, and the two hinge shafts are respectively passed through their respective wing plates 411 to realize the hinge connection between the hinge seat 41 and the conveying cylinder 11. In other embodiments, screws are provided on both sides of the conveying cylinder 11, and the two screws are respectively passed through their respective wing plates 411. Each screw is provided with a nut, which is located on the side of the wing plate 411 away from the conveying cylinder 11, so that the wing plate 411 can be pressed against the conveying cylinder 11 by the nut, thereby increasing the resistance when the second support leg 4 rotates and increasing the stability of the second support leg 4.

[0078] Preferably, there are two second legs 42, each corresponding to one of the two wing plates 411. Each second leg 42 is located directly below its corresponding wing plate 411 to improve the support stability of the conveying assembly 1.

[0079] Furthermore, refer to Figure 7 A reinforcing beam 413 is provided at the bottom of the seat plate 412. The reinforcing beam 413 is inclined, and the end of the reinforcing beam 413 away from the seat plate 412 is connected to the second support leg 42. The top view projection of the hinge position of the wing plate 411 and the conveyor cylinder 11 is located between the connection position of the reinforcing beam 413 and the seat plate 412 and the connection position of the second support leg 42 and the seat plate 412.

[0080] Because a reinforcing beam 413 is provided at the bottom of the seat plate 412, the reinforcing beam 413 is inclined, and the end of the reinforcing beam 413 away from the seat plate 412 is connected to the second support leg 42, the reinforcing beam 413, the seat plate 412, and the second support leg 42 together form a triangle to increase the connection stability between the second support leg 42 and the seat plate 412. Furthermore, because the top view projection of the hinge position between the wing plate 411 and the conveying cylinder 11 is located between the connection position of the reinforcing beam 413 and the seat plate 412 and the connection position of the second support leg 42 and the seat plate 412, the hinge position between the second support leg 4 and the conveying cylinder 11 is located on the side of the second support leg 42, which reduces the pressure on the second support leg 42 to a certain extent, thereby reducing the risk of sinking to the ground due to the large pressure on the second support leg 4, and further increasing the stability of the movable screw feeder.

[0081] This application does not specify the fixed connection method between the reinforcing beam 413 and the second leg 42 and the seat plate 412. The connection method between the two can be referred to as that between the first leg 32 and the connecting plate 312.

[0082] This application does not specify the method of fixing the reinforcing beam 413 to the second leg 42. Preferably, a connecting body 421 is provided between the two second legs 42, and one bottom end of the reinforcing beam 413 is fixedly connected to the connecting body 421 by bolts. In other embodiments, two reinforcing beams 413 can be provided corresponding to the two second legs 42, and each reinforcing beam 413 is directly connected to its corresponding second leg 42 by welding.

[0083] In other embodiments, the second support leg 4 may also be an H-shaped frame structure.

[0084] This application does not specify the arrangement of the conveyor cylinder 11; preferably, refer to... Figures 1 to 4 The conveying cylinder 11 is inclined, and the conveying shaft 12 has a first end with a relatively lower position and a second end with a relatively higher position. The two ends of the conveying cylinder 11 are respectively provided with a first support sleeve 114 and a second support sleeve 115 corresponding to the first end and the second end. The first end is provided with a first shaft head 121 extending out of the first support sleeve 114, and the second end is provided with a second shaft head 122 extending out of the second support sleeve 115. The first support sleeve 114 is provided with a tapered bearing 117 sleeved on the first shaft head 121, and the second support sleeve 115 is provided with a self-aligning bearing 119 sleeved on the second shaft head 122.

[0085] It is understandable that the conveying shaft 12 and the conveying cylinder 11 are coaxially arranged. Since the conveying cylinder 11 is inclined, the conveying shaft 12 is also inclined. The relatively lower end of the conveying cylinder 11 constitutes the beginning of the conveying process, and the relatively higher end of the conveying cylinder 11 constitutes the end of the conveying process.

[0086] It should be noted that the phrase "the conveyor shaft 12 has a first end that is relatively lower and a second end that is relatively higher" refers to a comparison of the two ends of the conveyor shaft 12.

[0087] Since the first support sleeve 114 is equipped with a tapered bearing 117 sleeved on the first shaft head 121, and the second support sleeve 115 is equipped with a self-aligning bearing 119 sleeved on the second shaft head 122, the tapered bearing 117, which is located at a relatively lower position on the conveying cylinder 11, can mainly bear the axial load of the conveying shaft 12, while the self-aligning bearing 119, which is located at a relatively higher position, can mainly bear the radial load of the conveying shaft 12. This improves the ability of the conveying shaft 12 to resist the impact load generated by the material jamming moment and increases the stability of the conveying shaft 12. In turn, it increases the stability of the movable screw feeder and reduces the failure rate of the movable screw feeder.

[0088] Preferably, the tilt angle of the conveyor shaft 12 is 12° to reduce the footprint of the movable screw feeder, optimize space, and replace vertical lifting equipment within a small tilt angle range. Compared with horizontal conveying equipment, moderate tilting can achieve low-cost material lifting with a small sacrifice in efficiency.

[0089] Furthermore, refer to Figures 1 to 4 Support members 116 are provided at both ends of the conveying cylinder 11. The first support sleeve 114 and the second support sleeve 115 are fixedly connected to the two support members 116, thereby increasing the stability of the first support sleeve 114 and the second support sleeve 115, and further increasing the stability of the conveying shaft 12.

[0090] This application does not specifically limit the structure of the support member 116. Preferably, the support member 116 is an I-beam fixedly connected to the end of the conveying cylinder 11 to ensure the stability of the support for the first support sleeve 114 or the second support sleeve 115. In other embodiments, the support member 116 may also be other structures capable of supporting the first support sleeve 114 or the second support sleeve 115, such as a plate structure, a T-shaped structure, etc.

[0091] In a preferred embodiment, refer to Figures 1 to 4 The drive assembly includes a drive motor 2, the output shaft of the drive motor 2 is connected to the first shaft head 121, a support beam 21 is provided on the side of the first support leg 3, the support beam 21 is connected to the mechanical slipper 5 provided on the first support leg 3, and support frames 211 connected to the support beam 21 are provided on both sides of the drive motor 2.

[0092] Specifically, the support beam 21 is fixedly connected to the mechanical slipper 5 located on the first support leg 3 via an auxiliary beam. On the one hand, this allows the support beam 21 to be located directly below the drive motor 2, thereby improving the support effect of the support beam 21 on the drive motor 2. On the other hand, the support beam 21 and the auxiliary beam can also be used to provide auxiliary support for the conveying assembly 1, thereby increasing the stability of the movable screw feeder.

[0093] Since both sides of the drive motor 2 are provided with support frames 211 connected to the support beam 21, and the support beam 21 is connected to the mechanical slipper 5 provided on the first support leg 3, the first support leg 3 can be used to support the drive motor 2, thereby increasing the stability of the drive motor 2 and avoiding the need to set up a separate support component to support the drive motor 2, thus reducing the production cost of the movable screw feeder; at the same time, since the output shaft of the drive motor 2 is connected to the first shaft head 121, the drive motor 2 is located at the lower end of the conveying cylinder 11, thereby reducing the overall height of the movable screw feeder, realizing the miniaturization design of the movable screw feeder, and lowering the center of gravity of the movable screw feeder to reduce the vibration amplitude of the movable screw feeder, thereby ensuring the stable operation of the movable screw feeder.

[0094] The better one is to refer to Figure 1 The support frame 211 is fixedly connected to the support beam 21. Support ears are provided on both sides of the drive motor 2. The top of the support frame 211 is connected to the support ears through a pin. On the one hand, the drive motor 2 and the support frame 211 are detachably connected. On the other hand, the support frame 211 is used to support the drive motor 2.

[0095] This application does not specifically limit the structure of the drive motor 2. Preferably, the drive motor 2 is a permanent magnet motor, which eliminates the need for a reducer and thus the intermediate transmission link, simplifying the design of the movable screw feeder, shortening the installation and commissioning time of the movable screw feeder, reducing its energy consumption, and decreasing its noise. Simultaneously, the permanent magnet motor can still output rated torque at low speeds, avoiding the risk of "stall and burnout" caused by the decrease in speed of traditional motors. In other embodiments, the drive motor 2 can also be an asynchronous motor, and a reducer needs to be installed between the asynchronous motor and the first shaft head 121.

[0096] Furthermore, refer to Figure 3 Both ends of the first support sleeve 114 are provided with first sealing plates 118 that are sleeved on the first shaft head 121, thereby sealing the first support sleeve 114 and improving the dustproof effect on the tapered bearing 117, thus extending the service life of the tapered bearing 117. The first support sleeve 114 is provided with an oil injection nozzle 133, which allows grease to be added to the first support sleeve 114, thereby extending the service life of the tapered bearing 117.

[0097] Preferably, two tapered bearings 117 are spaced apart and arranged opposite to each other, with an oil nozzle 133 located between the two tapered bearings 117, so that the grease entering the first support sleeve 114 through the oil nozzle 133 can enter the tapered bearing 117 to replenish the tapered bearing 117 with grease.

[0098] This application does not specifically limit the connection method between the first sealing plate 118 and the first support sleeve 114. Preferably, the first sealing plate 118 is fixedly connected to the first support sleeve 114 by bolts to increase the connection stability between the first sealing plate 118 and the first support sleeve 114. In other embodiments, the first sealing plate 118 can also be connected to the first support sleeve 114 by threaded connection or snap-fit.

[0099] Furthermore, refer to Figure 4 One end of the second support sleeve 115 is provided with a second sealing plate 131 fitted onto the second shaft head 122, and the other end of the second support sleeve 115 is provided with a cover 132. The second sealing plate 131 and the cover 132 can be used to seal the second support sleeve 115, thereby improving the dustproof effect on the self-aligning bearing 119 and extending the service life of the self-aligning bearing 119. The second support sleeve 115 is also provided with an oil injection nozzle 133, which can be used to add grease to the second support sleeve 115, thereby extending the service life of the self-aligning bearing 119.

[0100] It is understandable that the self-aligning bearing 119 has two rows of spaced-apart rollers, and the grease nipple 133 on the second support sleeve 115 is set to correspond to the gap between the two rows of rollers, so that the grease entering the second support sleeve 115 through the grease nipple 133 can directly contact the rollers.

[0101] In other embodiments, the conveyor cylinder 11 may also be arranged horizontally.

[0102] In a preferred embodiment, refer to Figure 1 The side of the conveyor cylinder 11 is provided with at least one inspection port and an inspection door 134 that can close and open the inspection port. The top end of the inspection door 134 is hinged to the conveyor cylinder 11, and the inspection door 134 is provided with a locking member 135 for locking the inspection door 134.

[0103] When the conveying assembly 1 is being inspected or when material is stuck inside the conveying cylinder 11, the locking member 135 is operated to unlock the locking member 135 from locking the inspection door 134. Then the inspection door 134 is flipped upward to open the inspection port. Then the conveying assembly 1 is inspected or the material stuck in the conveying cylinder 11 is removed, so as to facilitate the inspection of the conveying assembly 1 or the removal of the material stuck in the conveying cylinder 11.

[0104] Furthermore, since the top end of the inspection door 134 is hinged to the conveyor cylinder 11, compared to the solution where the bottom of the inspection door 134 is hinged to the conveyor cylinder 11, it avoids the situation where the inspection door 134 interferes with the staff and increases the difficulty of maintenance of the conveyor assembly 1. On the other hand, when closing the inspection port, only an initial downward flipping force needs to be applied to the inspection door 134, so that the inspection port can be closed by the weight of the inspection door 134 itself. At the same time, compared to the solution where the inspection door 134 flips downward, it also reduces the difficulty of locking the inspection door 134.

[0105] Preferably, multiple inspection ports are provided at intervals along the axial direction of the conveying cylinder 11 to further facilitate the maintenance of the conveying assembly 1.

[0106] This application does not specifically limit the structure of the locking member 135. Preferably, the locking member 135 is a pull-type door lock, and multiple pull-type door locks are spaced apart along the axial direction of the inspection door 134 to increase the locking effect on the inspection door 134 and ensure the sealing of the conveying cylinder 11. In other embodiments, the locking member 135 can also be an electromagnet, so as to use the magnetic field generated when the electromagnet is energized to magnetically attract the inspection door 134 to the conveying cylinder 11.

[0107] In a preferred embodiment, refer to Figure 1 and Figure 2 The top of the conveying cylinder 11 is provided with a feeding hopper 113 corresponding to the feed inlet 112, so as to guide the material by the feeding hopper 113 and at the same time allow a certain amount of material to accumulate at the feed inlet 112.

[0108] This application does not specifically limit the structure of the mechanical skate 5, which can adopt any of the following embodiments:

[0109] Implementation Method 1, in this implementation method, refer to Figures 5 to 7 The mechanical skid 5 includes a base plate 51, a top plate 52 spaced apart from the base plate 51, and a guide tube 53 disposed between the base plate 51 and the top plate 52, at least a portion of the guide tube 53 protruding from the outside of the base plate 51 and the top plate 52.

[0110] It is understood that the top plate 52 and the bottom plate 51 are arranged parallel to each other; the bottom end of the first leg 32 passes through the top plate 52 corresponding to it and is fixedly connected to the bottom plate 51, and the periphery of the first leg 32 is fixedly connected to the top plate 52 corresponding to it; the bottom end of the second leg 42 passes through the top plate 52 corresponding to it and is fixedly connected to the bottom plate 51, and the periphery of the second leg 42 is fixedly connected to the top plate 52 corresponding to it.

[0111] Since a guide tube 53 is provided between the top plate 52 and the bottom plate 51, and at least part of the guide tube 53 protrudes outside the bottom plate 51 and the top, on the one hand, when the movable screw feeder is moved, the guide tube 53 can also be used to guide the movable screw feeder to reduce the occurrence of the mechanical slipper 5 getting stuck on the ground, thereby further reducing the difficulty of moving the movable screw feeder and further improving the convenience of moving the movable screw feeder. On the other hand, it increases the structural strength of the mechanical slipper 5 to increase the stability of the movable screw feeder.

[0112] Preferably, four guide tubes 53 are provided along the axial direction of the top plate 52 and the bottom plate 51 to guide the movable screw feeder in multiple directions.

[0113] Preferably, half of the top view projection of the guide tube 53 coincides with the base plate 51, and the other half is located outside the base plate 51, so as to ensure the guiding effect of the mechanical slipper 5.

[0114] Implementation Method Two: In this implementation method, refer to... Figure 8 The mechanical skid 5 includes a base plate 51 and a reinforcing plate 54. The base plate 51 has a straight section and curved sections located at both ends of the straight section. The reinforcing plate 54 is located inside the curved section and connected to the curved section and the straight section.

[0115] It is understandable that the curved section is provided in two parts and is located at both ends of the straight section. The curved section is bent upwards, and the two adjacent sides of the reinforcing plate 54 are fixedly connected to the curved section and the straight section respectively.

[0116] Since the base plate 51 has a straight section and curved sections at both ends of the straight section, the curved sections can be used to guide the movable screw feeder when it is moved, thereby reducing the occurrence of the mechanical slipper 5 getting stuck on the ground. This further reduces the difficulty of moving the movable screw feeder and improves the convenience of moving it. Furthermore, since the reinforcing plate 54 is located inside the curved section and connects the curved section and the straight section, it increases the structural strength of the base plate 51, thereby increasing the stability of the movable screw feeder and reducing the manufacturing cost of the mechanical slipper 5.

[0117] Preferably, the reinforcing plate 54 is fixedly connected to the first leg 32 or the second support leg 4 corresponding to itself on the side opposite to the bending section. This increases the connection stability between the mechanical slipper 5 and the first leg 32 or the second support leg 42, and also increases the structural strength of the mechanical slipper 5.

[0119] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
