Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices, and more specifically, to an unloading device. Background Technology

[0002] A typical brine salt production system includes several sequential salt processing steps such as crystallization, collection, washing, dehydration, drying, screening, and storage. Between each step, a discharge device is usually used to unload the salt produced by the upstream equipment onto a scraper conveyor, which then continuously and quantitatively transfers the salt to the downstream equipment.

[0003] In the prior art, Chinese Patent No. CN203667615U discloses a novel material distribution device for a unloading machine, which includes a material distribution mechanism and an unloading mechanism arranged sequentially. The material distribution mechanism's discharge port can connect with the unloading mechanism. The material distribution mechanism includes a material distribution box and a pushing device. A material inlet is located at the top of one side of the material distribution box, and a discharge port is located at the bottom of the other side. The discharge port connects with the unloading mechanism. The pushing device includes a pushing plate disposed within the material distribution box. The pushing plate can reciprocate between the end where the material inlet is located and the end where the material discharge port is located, to quantitatively push the material on the side where the material inlet is located to the discharge port.

[0004] However, when the above-mentioned unloading and distributing device is applied to the salt field production system, there may be situations where the salt has a high moisture content. This may increase the friction between the salt and the bottom plate of the distributing box, increase the pushing resistance of the pusher plate, slow down the movement speed of the salt, and affect the unloading efficiency.

[0007] Furthermore, the drive assembly includes: a first drive member; a lifting member fixed on the movable plate, the lifting member being movably and vertically arranged, the lifting member forming the drive end of the drive assembly; and a first transmission assembly disposed between the first drive member and the lifting member, the first drive member driving the lifting member to move up and down through the first transmission assembly so that the movable plate is movably arranged in the height direction.

[0008] Furthermore, the first driving member has an output shaft, and the first transmission assembly includes: a first connecting part disposed on the output shaft; a transmission shaft disposed on the first connecting part, the transmission shaft being located below the lifting member, and the transmission shaft being eccentrically disposed with respect to the output shaft; and a connecting rod, one end of which is hinged to the transmission shaft and the other end of which is hinged to the lifting member, the hinge axis between the connecting rod and the transmission shaft and the hinge axis between the connecting rod and the lifting member being parallel.

[0009] Furthermore, the first transmission assembly also includes a second connecting part, which is disposed at the end of the transmission shaft away from the first connecting part. The second connecting part is rotatably connected to the first material box via a rotating shaft, and the rotation axis of the second connecting part is collinear with the axis of the output shaft.

[0010] Furthermore, the unloading device also includes a support assembly, which includes: a support plate fixed on the first material box and located below the movable plate; and an elastic support member disposed between the support plate and the movable plate to elastically support the movable plate.

[0011] Furthermore, the support plate is provided with a guide hole that extends vertically, and the end of the drive end that is connected to the movable plate passes through the guide hole and is guided and engaged by the guide hole.

[0012] Furthermore, there are multiple support components, which are distributed at intervals along the inclined direction of the movable plate. The driving end includes multiple guide sections corresponding to one of the support components. The top end of the guide section is fixedly connected to the movable plate, and the guide section passes through the guide hole and elastic support member on one of the support plates.

[0013] Furthermore, the drive assembly includes a first drive member having an output shaft, and the unloading device further includes: a material dispersing member disposed in the discharge chamber, the material dispersing member being rotatably disposed relative to the second material box to disperse the material located in the discharge chamber; and a second transmission assembly including a first pulley, a second pulley, and a belt, the first pulley being disposed on the output shaft, the second pulley being disposed at the end of the material dispersing member, and the belt being sleeved on the outer periphery of the first pulley and the second pulley.

After the material stabilizes on the fixed plate, the pusher plate of the pusher assembly pushes the material on the fixed plate through the movable plate to the material inlet of the second material box, and then falls to the designated position through the second material box. During this process, the drive assembly drives the movable plate to move in the height direction through the drive end, causing the movable plate to vibrate in the height direction. At the same time, since the movable plate itself is inclined, the fluidity of the material on the movable plate is enhanced, which promotes the sliding speed of the material on the movable plate and improves the unloading efficiency.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] like Figures 1 to 4As shown, this utility model embodiment provides a unloading device, which includes: a first material box 10 having a material transfer chamber 101; the bottom plate of the first material box 10 includes a fixed plate 11 and a movable plate 12 arranged sequentially; the fixed plate 11 is used to receive the material conveyed in the previous process; the movable plate 12 is inclined downward relative to the fixed plate 11 and is movably arranged relative to the fixed plate 11 in the height direction; the maximum height of the movable plate 12 is less than or equal to the height of the fixed plate 11; and a driving assembly 20 having a driving end that is reciprocally movable along the height direction and is driven by the movable plate 12. The first material box 10 is connected to drive the movable plate 12 to move in the height direction; the second material box 30 is located on the side of the movable plate 12 away from the fixed plate 11. The second material box 30 has a material inlet 301, a material discharge chamber 302 and a material outlet 303 connected in sequence. The end of the movable plate 12 away from the fixed plate 11 faces the material inlet 301; the pushing assembly 40 includes a pushing plate 41 located in the material transfer chamber 101. The pushing plate 41 can reciprocate relative to the first material box 10 along the distribution direction of the fixed plate 11 and the movable plate 12 to push the material on the fixed plate 11 through the movable plate 12 to the material inlet 301 of the second material box 30.

[0037] The technical solution of this utility model can improve unloading efficiency, especially for materials with high moisture content. Specifically, during unloading, materials such as salt first fall onto the fixed plate 11, which acts as an initial carrier responsible for the initial reception and transition of the material. After the material stabilizes on the fixed plate 11, the pusher plate 41 of the pusher assembly 40 pushes the material on the fixed plate 11 through the movable plate 12 to the material inlet 301 of the second material box 30, and then falls to the designated position through the second material box 30. During this process, the drive assembly 20 drives the movable plate 12 to move in the height direction through the drive end, causing the movable plate 12 to vibrate in the height direction. At the same time, since the movable plate 12 itself is inclined, the fluidity of the material on the movable plate 12 is enhanced, which promotes the sliding speed of the material on the movable plate 12 and improves the unloading efficiency.

[0038] It is understandable that materials with high moisture content, such as wet salt, will often have an increased coefficient of friction when in contact with the fixed plate 11 and movable plate 12 of the first material bin 10 due to the presence of moisture on their surface. This results in greater friction between the wet salt and the fixed plate 11 and movable plate 12 of the first material bin 10, affecting the pushing speed of the pusher plate 41 and the unloading speed. In practical use, the first material bin 10 and the second material bin 30 can be positioned above the beginning of the conveying direction of the scraper conveyor, so that materials such as salt fall onto the scraper conveyor through the first material bin 10 and the second material bin 30.

[0039] like Figure 1As shown in the embodiment of this solution, the first material box 10 also includes a side enclosure 13. The side enclosure 13 is arranged around the outer perimeter of the fixed plate 11 and the movable plate 12 on three sides. The side enclosure 13 has an open structure at the end of the movable plate 12 away from the fixed plate 11. The side enclosure 13, the fixed plate 11 and the movable plate 12 form a material transfer cavity 101.

[0040] Furthermore, the fixed plate 11 is a horizontally arranged rectangular plate structure, and the movable plate 12 is an inclined rectangular plate structure.

[0041] It should be noted that the maximum height of the movable plate 12 refers to the height of the end of the movable plate 12 closest to the fixed plate 11 when the movable plate 12 is in its highest position. The top of the movable plate 12 can be located below the fixed plate 11 or on the side of the fixed plate 11, as long as it ensures that the material does not fall through the gap between the two when it is pushed from the fixed plate 11 to the movable plate 12.

[0042] like Figure 2 and Figure 3 As shown in the embodiment of this solution, the drive assembly 20 includes: a first drive member 21; a lifting member 22, fixed on the movable plate 12, the lifting member 22 being movably and vertically arranged, the lifting member 22 forming the drive end of the drive assembly 20; and a first transmission assembly 23, disposed between the first drive member 21 and the lifting member 22, the first drive member 21 driving the lifting member 22 to rise and fall through the first transmission assembly 23 so that the movable plate 12 is movably arranged in the height direction.

[0043] Specifically, the lifting component 22 is fixed to the bottom of the movable plate 12, and the first driving component 21 and the first transmission component 23 are both located below the movable plate 12.

[0044] Furthermore, the first driving member 21 has an output shaft, and the first transmission assembly 23 includes: a first connecting part 231 disposed on the output shaft; a transmission shaft 232 disposed on the first connecting part 231, the transmission shaft 232 being located below the lifting member 22, and the transmission shaft 232 being eccentrically disposed with respect to the output shaft; and a connecting rod 233, one end of which is hinged to the transmission shaft 232, and the other end of which is hinged to the lifting member 22, the hinge axis between the connecting rod 233 and the transmission shaft 232, and the hinge axis between the connecting rod 233 and the lifting member 22 being parallel.

[0045] Specifically, the first driving member 21 drives the transmission shaft 232 in the first transmission assembly 23 to rotate around the axis of the output shaft by rotating the output shaft, and then the rotation of the transmission shaft 232 is converted into the vertical lifting motion of the lifting member 22 by the connecting rod 233, thereby causing the movable plate 12 to vibrate in the height direction.

[0046] In this embodiment, the first connecting part 231 is a circular plate-shaped structure, and the first connecting part 231 is coaxial with the output shaft. One end of the transmission shaft 232 is fixed at the periphery of the first connecting part 231.

[0047] The first driving component 21 is a drive motor. The output shaft extends horizontally, and the direction of the output shaft is perpendicular to the direction from the fixed plate 11 to the movable plate 12.

[0048] Furthermore, the first transmission assembly 23 also includes a second connecting portion 234, disposed at the end of the transmission shaft 232 away from the first connecting portion 231. The second connecting portion 234 is rotatably connected to the first material box 10 via a rotating shaft, and the rotation axis of the second connecting portion 234 is collinear with the axis of the output shaft. The rotation of the transmission shaft 232 drives the second connecting portion 234 to rotate around the rotating shaft. This arrangement can improve the stability of the rotation of the transmission shaft 232 and reduce the possibility of the transmission shaft 232 shaking.

[0049] Specifically, the drive shaft 232 passes through the end of the connecting rod 233 away from the lifting member 22, and the second connecting part 234 and the first connecting part 231 are symmetrically arranged with respect to the connection position between the connecting rod 233 and the drive shaft 232. This arrangement can further improve the rotational stability of the drive shaft 232.

[0050] Furthermore, the unloading device also includes a support assembly 50, which includes: a support plate 51 fixed on the first material box 10 and located below the movable plate 12; and an elastic support member 52 disposed between the support plate 51 and the movable plate 12 to elastically support the movable plate 12. The support assembly 50, through the combination of the support plate 51 and the elastic support member 52, provides stable support for the movable plate 12 and also ensures the smoothness of its vibrational movement under the action of the drive assembly 20.

[0051] In this embodiment, the extension direction of the support plate 51 is perpendicular to the direction from the movable plate 12 to the fixed plate 11. Two springs are provided on each support plate 51, and the two springs are spaced apart along the extension direction of the support plate 51. This arrangement results in a simple structure, and the two springs improve the stability of supporting the movable plate 12.

[0052] Furthermore, the support plate 51 is provided with a guide hole that extends vertically. One end of the drive end, which is connected to the movable plate 12, passes through the guide hole and is guided and engaged by the guide hole. This arrangement can improve the stability of the drive end during the lifting process and improve the vibration stability of the movable plate 12.

[0053] In this embodiment, there are multiple support components 50, which are spaced apart along the inclined direction of the movable plate 12. This arrangement further improves the stability of supporting the movable plate 12.

[0054] Furthermore, the drive end includes a connecting section 222 and multiple guide sections 221, that is, the lifting component 22 includes a connecting section 222 and multiple guide sections 221. The connecting section 222 is a rod-shaped structure extending in the horizontal direction, and the extension direction of the connecting section 222 is parallel to the extension direction of the transmission shaft 232. The guide sections 221 are rod-shaped structures extending in the vertical direction, and the guide sections 221 are distributed at intervals along the extension direction of the connecting section 222. The top end of each guide section 221 is fixed to the bottom of the movable plate 12.

[0055] In this embodiment, a plurality of guide holes are provided on the support plate 51 corresponding to the end of the movable plate 12 near the fixed plate 11. The plurality of guide holes on the support plate 51 are spaced apart along the length direction of the support plate 51, and the plurality of guide holes are provided one-to-one with a plurality of guide segments 221. Each guide segment 221 passes through the corresponding guide hole and is guided and engaged with the corresponding guide hole. This arrangement can improve the stability of the lifting component 22 during the lifting process.

[0056] Furthermore, a plurality of elastic support members 52 are provided on the support plate 51 corresponding to the end of the movable plate 12 near the fixed plate 11. Each elastic support member 52 is corresponding to a plurality of guide sections 221, and each elastic support member 52 is fitted onto the corresponding guide section 221. This arrangement can improve the stability of the elastic support members 52 during the extension and retraction process.

[0057] Specifically, the elastic support member 52 can be configured as a spring.

[0058] like Figure 1 , Figure 2 and Figure 4 As shown, the unloading device further includes: a material dispersing component 60, which is disposed in the material discharge chamber 302. The material dispersing component 60 is rotatably disposed relative to the second material box 30 to disperse the material located in the material discharge chamber 302; and a second transmission assembly 70, which includes a first pulley 71, a second pulley 72, and a belt 73. The first pulley 71 is disposed on the output shaft, the second pulley 72 is disposed at the end of the material dispersing component 60, and the belt 73 is sleeved on the outer periphery of the first pulley 71 and the second pulley 72.

[0059] The material dispersing component 60 enables the dispersion and mixing of materials within the discharge chamber 302, reducing or preventing blockage or accumulation of materials within the discharge chamber 302 and improving the smoothness of material descent. The first pulley 71 is mounted on the output shaft, allowing the first drive component 21 to simultaneously drive both the material dispersing component 60 and the movable plate 12.

[0060] In this embodiment, the material dispersing component 60 includes a main shaft 61 and a plurality of dispersing blades 62 disposed on the main shaft, the plurality of dispersing blades 62 being distributed circumferentially along the main shaft 61. The main shaft 61 is rotatably connected to the second material box 30, one end of the main shaft 61 protruding through the side wall of the second material box 30, and a second pulley 72 is fixed to the end of the main shaft 61 that protrudes through the second material box 30.

[0061] Specifically, when the unloading device is working, the first drive unit 21 is activated. The output shaft of the first drive unit 21 drives the transmission shaft 232 in the first transmission assembly 23 to rotate around the axis of the output shaft. Then, through the connecting rod 233, the rotation of the transmission shaft 232 is converted into the vertical lifting motion of the lifting component 22, thereby causing the movable plate 12 to vibrate in the height direction. At the same time as the output shaft of the first drive unit 21 rotates, it drives the first pulley 71 to rotate. Under the action of the belt 73, the second pulley 72 drives the material dispersing component 60 to rotate.

[0062] In this embodiment, the first drive unit 21 is located on the same side as the first material box 10 and the second material box 30, one end of the main shaft extends to the side wall of the second material box 30, and the second pulley 72 is located outside the second material box 30 and fixed on the end of the main shaft that extends out of the second material box 30.

[0063] Furthermore, the first pulley 71 and the first connecting portion 231 are spaced apart along the axial direction of the output shaft, and the first connecting portion 231 is disposed on the end of the output shaft away from the main body of the first driving member 21.

[0064] Furthermore, the pushing assembly 40 also includes a second driving member 42, located outside the first material box 10. The second driving member 42 is disposed on the side wall of the first material box 10 away from the movable plate 12. The second driving member 42 has a telescopic shaft 421, which passes through the side wall of the first material box 10 away from the movable plate 12. The telescopic shaft 421 is fixed to the pushing plate 41 to drive the pushing plate 41 to reciprocate. The second driving member 42 can be configured as a driving cylinder or a driving hydraulic cylinder. The configuration of a driving cylinder or a driving hydraulic cylinder has a simple structure and strong stability.

[0065] Furthermore, the unloading device also includes: a limiting member 80, connected to the inner wall of the first material box 10 and located on the moving path of the pusher plate 41; a resetting member 81, one end connected to the limiting member 80 and the other end connected to the pusher plate 41, the resetting member 81 being used to apply a force to the pusher plate 41 from the movable plate 12 towards the fixed plate 11; and a guide member 82, disposed on the inner wall of the first material box 10, the resetting member 81 and the guide member 82 providing a guiding fit. The limiting member 80 limits the maximum travel of the pusher plate 41; the guide member 82 guides the movement of the pusher plate 41; and the resetting member 81 allows the pusher plate 41 to reset more smoothly during its movement from the movable plate 12 to the fixed plate 11.

[0066] Specifically, the limiting member 80 is a block structure, the guide member 82 is a rod structure, the extension direction of the guide member 82 is the same as the movement direction of the pusher plate 41, the guide member 82 passes through the pusher plate 41, the reset member 81 is a reset spring, the reset member 81 is sleeved on the guide member 82, and the distribution direction of the reset member 81 to the pusher plate 41 is the same as the distribution direction of the movable plate 12 to the fixed plate 11.

[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0068] 1. The movable plate 12 is movably set in the height direction, and its tilt angle is set, which can increase the speed at which the material falls from the movable plate 12 to the second material box 30, thereby improving the unloading efficiency.

[0069] 2. The material dispersing component 60 can reduce the accumulation or blockage of materials in the second material box 30 and improve the falling speed of materials;

[0070] 3. The support component 50 provides elastic support for the movable plate 12, improving the smoothness of the movable plate 12's movement in the height direction.

[0071] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
