Description

Technical Field

[0001] This utility model belongs to the technical field of plow-type unloaders, specifically a single-sided bidirectional plow-type unloader. Background Technology

[0002] A plow-type unloader is a material unloading device installed on a belt conveyor. It is generally divided into double-sided plow-type unloaders and single-sided plow-type unloaders. A double-sided plow-type unloader can unload material onto both sides of the conveyor belt simultaneously, while a single-sided plow-type unloader can generally only unload material onto one fixed side of the conveyor belt.

[0003] A search revealed that patent CN221234683U discloses a belt-driven electro-hydraulic controlled plow-type unloader, relating to the field of coke production equipment technology. The device includes a conveyor belt, support frame, material support plate, fixing frame, and plow plate. Leather is mounted on the bottom of the plow plate via a fixing mechanism, and the top of the support frame is equipped with a drive mechanism that rotates the fixing frame. This invention first symmetrically bends the two long sides of the leather inwards, then attaches elastic clips to both ends of the leather via slots. Next, the two sets of elastic clips and the leather are inserted into the fixing clips at both ends of the plow plate, and the fastening nuts on the bolts are tightened. The fixing clips simultaneously clamp the elastic clips and the leather, fixing the leather to the bottom of the plow plate. For disassembly, simply loosen the fastening nuts on the bolts, allowing the leather to be easily removed from the bottom of the plow plate. This solves the problem of inconvenience in disassembling and replacing worn leather using the existing riveting method.

[0004] Analysis of the above technical solutions reveals that when fixing leather, only the two ends of the leather can be secured to the two ends of the plow plate, while the middle and other parts of the leather are not secured. Therefore, the leather is prone to deformation when used on the plow plate, and fixing and removing the leather requires tools, making the operation inconvenient. To address these issues, we provide a single-sided, double-acting plow-type unloader. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a single-sided bidirectional plow-type unloader.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-sided bidirectional plow-type unloader, comprising a support and a plow plate. Two opposing L-shaped frames are fixedly connected to the top of the plow plate, and a rotating frame is fixedly connected between the tops of the two L-shaped frames. A swing mechanism for driving the rotating frame to swing is provided on the support. Side frames are fixedly connected to both the front and back of the plow plate, and a pressing plate is slidably disposed within each side frame. Leather is provided on both the front and back of the plow plate, and the side frames press against the leather. A lifting plate is provided above the plow plate, and both ends of the lifting plate are movably connected to the tops of the two pressing plates. Hydraulic cylinders are installed on both L-shaped frames, and the extension and retraction ends of both hydraulic cylinders are fixedly connected to the lifting plate.

[0007] Preferably, the swing mechanism includes an electro-hydraulic actuator and a swing frame. The electro-hydraulic actuator is hinged to the top of the support, and the swing frame is hinged to the inner wall of the support. A protrusion is fixedly connected to the front end of the swing frame. The telescopic end of the electro-hydraulic actuator is hinged to the top of the protrusion. A motor is installed in the middle of the protrusion. The output end of the motor is connected to the middle of the rotating frame. The middle of the rotating frame is movably connected to the front end of the swing frame.

[0008] Preferably, a positioning shaft is fixedly connected to the middle of the rotating frame, and the front end of the swing frame is rotatably sleeved on the surface of the positioning shaft.

[0009] Preferably, each of the two extrusion plates has a limiting groove at its top, and the two bottom ends of the lifting plate are slidably disposed in the limiting groove.

[0010] Preferably, inclined plates are fixedly connected to the sides of both extrusion plates, and the inclined plates are slidably disposed on the inclined surface of the inner wall of the side frame. Leaf springs are fixedly connected to the inner walls of the two side frames, and the side frames are in contact with the leaf springs.

[0011] Preferably, each of the two extrusion plates has an installation groove on one of its adjacent sides, and a protrusion is slidably disposed in each installation groove. The surface of the protrusion is pressed against the surface of the leather. Several springs are fixedly connected to the side of each protrusion away from the leather, and one end of the spring is fixedly connected to the inner wall of the installation groove.

[0012] Preferably, an extension plate is fixedly connected to the bottom end of each of the two extrusion plates, and the bottom end of the extension plate is in contact with the leather.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the coordinated arrangement of a plow plate, an L-shaped frame, a rotating frame, side frames, a pressing plate, leather, a lifting plate, and hydraulic cylinders, facilitates the quick replacement and fixation of leather. When it is necessary to disassemble the leather, simply use the synchronous operation of two hydraulic cylinders to move the lifting plate upwards, which will cause the two pressing plates to move away from the two pieces of leather, thus allowing the leather to be directly removed from the plow plate. Then, place the new leather between the pressing plate and the plow plate for initial positioning. Next, use the synchronous operation of the two hydraulic cylinders to drive the lifting plate downwards, which will cause the two pressing plates to slide downwards within the two side frames, ultimately pressing and fixing the two pieces of leather onto the plow plate. Therefore, no additional auxiliary tools are needed, and no manual fixing operation is required. The fixation of the leather is more stable, and the fixation range of the leather is increased, preventing the middle of the leather from loosening.

[0015] 2. This utility model, through a swing mechanism, enables the swing frame to swing upwards when the plow plate is not in use, by retracting the telescopic end of the electro-hydraulic push rod. This, in turn, causes the rotating frame, L-shaped frame, and plow plate to swing upwards together, moving the plow plate away from the conveyor belt. When the plow plate needs to be used for unloading, simply push the telescopic end of the electro-hydraulic push rod downwards to swing the swing frame downwards, thus enabling the normal use of the plow plate. When it is necessary to control the plow plate to switch sides for unloading, simply rotate the middle part of the rotating frame at the front end of the swing frame by the operation of the motor, thereby causing the plow plate to swing and adjust the angle, achieving the effect of switching sides of the plow plate and improving the practicality of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, such as Figure 1-6As shown, this embodiment proposes a single-sided bidirectional plow-type unloader, including a support 1 and a plow plate 12. Two opposing L-shaped frames 5 are fixedly connected to the top of the plow plate 12, and a rotating frame 4 is fixedly connected between the tops of the two L-shaped frames 5. The two ends of the rotating frame 4 are respectively fixed to the tops of the two L-shaped frames 5, thus enabling the plow plate 12 to unload material not only from the front but also from the back, ensuring bidirectional unloading. The support 1 is equipped with a swing mechanism for driving the rotating frame 4 to swing. The swing mechanism enables the rotating frame 4 to swing, thereby driving the plow plate 12 to swing. The plow plate 12 can be moved upwards when not in use, and the angle of the rotating frame 4 can also be adjusted, allowing the plow plate 12 to unload material on the conveyor belt. Side frames 8 are fixed to both the front and back of the plow plate 12. The inner walls of the side frames 8 are sloped and located at the top of the plow plate 12, ensuring normal material unloading. A pressing plate 9 is slidably installed within each side frame 8, and when the pressing plate 9 slides downwards within the side frame 8, it moves towards one side of the plow plate 12. Leather 10 is provided on both the front and back of the plow plate 12, and the side frames 8 press against the leather 10. The plow plate 7 is provided, with its two ends movably connected to the tops of two pressing plates 9. Hydraulic cylinders 6 are mounted on both L-shaped frames 5, and the telescopic ends of the two hydraulic cylinders 6 are fixed to the plow plate 7. This structure facilitates quick replacement and fixation of the leather 10. When the leather 10 needs to be removed, the synchronous operation of the two hydraulic cylinders 6 moves the plow plate 7 upwards, causing the two pressing plates 9 to move away from the two leather 10s, allowing the leather 10 to be directly removed from the plow plate 12. Then, a new leather 10 is placed on the pressing plates 9 and... Initial positioning is achieved between the plow plates 12. Then, the lifting plate 7 is moved downwards by the synchronous operation of the two hydraulic cylinders 6, which in turn causes the two pressing plates 9 to slide downwards within the two side frames 8, ultimately pressing and fixing the two leathers 10 onto the plow plates 12. This eliminates the need for additional auxiliary tools, making the fixing of the leathers 10 more stable and increasing the fixing range of the leathers 10, preventing the middle of the leathers 10 from loosening. The machinery, parts, and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0025] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0026] like Figure 1 , Figure 4 and Figure 6As shown, the swing mechanism includes an electro-hydraulic actuator 2 and a swing frame 3. The electro-hydraulic actuator 2 is hinged to the top of the support 1, and the swing frame 3 is hinged to the inner wall of the support 1. A protrusion 17 is fixedly connected to the front end of the swing frame 3. The telescopic end of the electro-hydraulic actuator 2 is hinged to the top of the protrusion 17. A motor 18 is installed in the middle of the protrusion 17. The output end of the motor 18 is connected to the middle of the rotating frame 4. The middle of the rotating frame 4 is movably connected to the front end of the swing frame 3. The motor 18 is a worm gear motor, so when the motor 18 stops running, the rotating frame 4 will not swing easily. The motor 18 has a self-locking effect, thereby ensuring the stable use of the plow plate 12. With the above structure, when the plow plate 1... 2. When not in use, the retraction of the telescopic end of the electro-hydraulic actuator 2 pulls the swing frame 3 upward, thereby causing the rotating frame 4, L-shaped frame 5, and plow plate 12 to swing upward together, moving the plow plate 12 away from the conveyor belt. When the plow plate 12 needs to be used for unloading, simply push the telescopic end of the electro-hydraulic actuator 2 downward to drive the swing frame 3 downward, thus achieving normal use of the plow plate 12. When it is necessary to control the plow plate 12 to switch sides for unloading, simply rotate the middle part of the rotating frame 4 at the front end of the swing frame 3 through the operation of the motor 18, thereby driving the plow plate 12 to swing and adjust the angle, achieving the effect of switching sides of the plow plate 12 and improving the practicality of the device.

[0027] like Figure 4 and Figure 6 As shown, a positioning shaft 16 is fixedly connected to the middle of the rotating frame 4, and the front end of the swing frame 3 is rotatably sleeved on the surface of the positioning shaft 16. With the positioning shaft 16, when the rotating frame 4 rotates under the operation of the motor 18, it will rotate at the front end of the swing frame 3 through the positioning shaft 16. This not only positions the rotating frame 4, but also ensures that the swing frame 3 will also drive the rotating frame 4 to swing when it swings.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, each of the two extrusion plates 9 has a limiting groove 14 at its top. The two bottom ends of the lifting plate 7 are slidably disposed in the limiting groove 14. With the setting of the limiting groove 14, the lifting plate 7 can lift and lower the two extrusion plates 9 together. Moreover, the bottom width of the lifting plate 7 is smaller than the size of the limiting groove 14. Therefore, when the extrusion plate 9 moves, it will also move at the bottom of the lifting plate 7, ensuring the normal use of the extrusion plate 9.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, inclined plates 15 are fixedly connected to the sides of both extrusion plates 9, and the inclined plates 15 are slidably disposed on the inclined surface of the inner wall of the side frame 8. Leaf springs 19 are fixedly connected to the inner walls of the two side frames 8, and the side frames 8 are in contact with the leaf springs 19. With the above structure, when the extrusion plates 9 move downward, the extrusion plates 9 will automatically move toward one side of the plow plate 12, which facilitates the extrusion and fixing of the leather 10 on the plow plate 12.

[0030] like Figure 5 As shown, each of the two extrusion plates 9 has an installation groove 20 on one of its adjacent sides. A protrusion 17 is slidably disposed in each installation groove 20, and the surface of the protrusion 17 is pressed against the surface of the leather 10. Several springs 13 are fixedly connected to the side of each protrusion 17 away from the leather 10, and one end of the spring 13 is fixedly connected to the inner wall of the installation groove 20. With the above structure, the leather 10 can be initially positioned and fixed without the need for continuous manual support. In specific operation, the top of the leather 10 is simply inserted between the extrusion plate 9 and the plow plate 12, so that the protrusion 17 will press against the surface of the leather 10 under the elastic force of the spring 13, thereby preventing the leather 10 from tilting or moving at will. When the extrusion plate 9 is used to press and fix the leather 10, the protrusion 17 will slide into the installation groove 20 and press against the spring 13.

[0031] like Figures 1 to 4 As shown, the bottom ends of the two extrusion plates 9 are fixedly connected to extension plates 11, and the bottom ends of the extension plates 11 are in contact with the leather 10. With the extension plates 11, the tightness of the leather 10 on the plow plate 12 is improved, and the material in the unloading process is also guided to avoid the material from accumulating upward from the surface of the leather 10 into the extrusion plates 9.

[0032] The working principle and usage process of this utility model are as follows: When using the plow plate 12 for unloading, simply push the telescopic end of the electro-hydraulic push rod 2 downwards to drive the swing frame 3 to swing downwards, thus realizing the normal use of the plow plate 12. When it is necessary to control the plow plate 12 to switch sides for unloading, simply rotate the middle part of the rotating frame 4 at the front end of the swing frame 3 through the operation of the motor 18, thus driving the plow plate 12 to swing and adjust the angle, achieving the effect of switching sides of the plow plate 12. When the plow plate 12 is not in use, retracting the telescopic end of the electro-hydraulic push rod 2 will pull the swing frame 3 upwards, thereby driving the rotating frame 4, L-shaped frame 5 and plow plate 12 to swing upwards together, so that the plow plate 12 is away from the conveyor belt. When it is necessary to disassemble the leather 10, simply use... The synchronous operation of the two hydraulic cylinders 6 moves the lifting plate 7 upward, which moves the two extrusion plates 9 away from the two leathers 10, allowing the leathers 10 to be removed directly from the plow plate 12. Then, the new leather 10 is placed between the extrusion plates 9 and the plow plate 12 for initial positioning. Next, the synchronous operation of the two hydraulic cylinders 6 drives the lifting plate 7 downward, causing the two extrusion plates 9 to slide downward within the two side frames 8. As they slide, the extrusion plates 9 also move toward the plow plate 12, ultimately pressing and fixing the two leathers 10 onto the plow plate 12. This eliminates the need for additional auxiliary tools, making the fixation of the leathers 10 more stable and increasing the fixation range, preventing the middle of the leathers 10 from loosening.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
