Description

Technical Field

[0001] The present invention relates to the technical field of concentrate equipment, and particularly relates to a dust suppression unloading device. Background Art

[0002] Concentrate refers to the concentrate powder obtained by processing natural ore through crushing, grinding, ore dressing, etc.; the ore with a low grade of valuable metal is mechanically enriched (or physically enriched), such as through radioactive separation, gravity separation, flotation and other ore dressing processes, to obtain ore with a certain yield and a relatively high grade of valuable metal. This part of the ore enriched with valuable metal is the concentrate. The concentrate is the final product of the ore dressing plant and is the raw material for sintering pellets before smelting. The concentrate with the main and impurity component contents meeting the national standards obtained from the last operation of the ore dressing plant is called qualified concentrate.

[0003] Currently, every time the ore truck unloads, some concentrates are lifted, causing the concentrates to scatter outside the unloading area. On the one hand, it will pollute the working environment of the staff, and on the other hand, for the concentrates scattered outside the unloading area, they will adhere to different equipment, such as being carried out by adhering to the wheels during transportation, making it difficult to recover, resulting in waste of resources. Summary of the Invention

[0004] The purpose of the present invention is to solve the above deficiencies and provide a dust suppression unloading device.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A dust suppression unloading device includes a vehicle body, wheels provided at the bottom of the vehicle body, a material storage hopper rotatably provided on the vehicle body, a first cylinder provided on the vehicle body and used to drive the material storage hopper to rotate, and a closing cover rotatably provided on the material storage hopper and used to block the material storage hopper. It further includes:

[0007] A dust suppression structure is provided at one end of the material storage hopper close to the closing cover. When the material storage hopper rotates for unloading, it is used to form a closed space in the unloading area to surround the unloading area.

[0008] Preferably, the dust suppression structure includes:

[0009] A U-shaped plate is horizontally slidably provided on the vehicle body and forms a "mouth"-shaped closed area together with the vehicle body when sliding outwards. The vehicle body is provided with a second chute for the U-shaped plate to slide.

[0010] A top plate is vertically slidably provided on the top of the U-shaped plate. When the U-shaped plate slides outwards, it slides upwards, and when sliding upwards, it pushes the closing cover to rotate.

[0011] The bottom closure is vertically slidably disposed at the bottom of the U-shaped plate, sliding until it contacts the ground;

[0012] A movable plate is disposed above the U-shaped plate and slidably mounted on the vehicle body, and the vehicle body is provided with a first sliding groove for the movable plate to slide.

[0013] A driving component is used to drive the U-shaped plate and the moving plate to slide laterally and to drive the top plate and the bottom closure to slide vertically.

[0014] Preferably, the driving component includes:

[0015] The second cylinder is located in the second slide groove and is used to drive the U-shaped plate to slide laterally;

[0016] The second spring is located in the first groove. The two sides of the cover are connected to baffles that limit the movement of the moving plate. When the cover is closed to block the hopper, the spring is compressed and returns to its original state when the cover is opened, allowing the moving plate to slide laterally.

[0017] A first driving component is disposed on the U-shaped plate and is used to drive the top plate to slide vertically;

[0018] The second driving component is disposed on the U-shaped plate and is used to drive the bottom closure component to slide vertically.

[0019] Preferably, the first driving element includes:

[0020] A slider is horizontally mounted on the U-shaped plate;

[0021] The swing plate is hinged at one end to the top plate and at the other end to the slider;

[0022] The first spring is vertically disposed on the U-shaped plate and connected to the bottom end of the top plate;

[0023] When the second cylinder drives the U-shaped plate to slide laterally outward, the top plate slides upward under the action of the first spring and the swing plate.

[0024] Preferably, the U-shaped plate is provided with a guide rod to guide the slider when it slides, and the U-shaped plate is provided with a first fixing block for fixing the guide rod;

[0025] The bottom end of the top plate is slidably provided with a guide post for guiding the first spring. The top plate is sleeved on the guide post, the first spring is sleeved on the guide post, and the bottom end of the guide post is connected to a second fixing block.

[0026] Preferably, the second driving element includes:

[0027] The first toothed plate is connected to the bottom end of the top plate;

[0028] A gear is rotatably mounted on the U-shaped plate and meshes with the first toothed plate.

[0029] The second toothed plate is slidably disposed on the U-shaped plate, meshing with the gear and connected to the bottom closure.

[0030] Preferably, the bottom closure includes a base plate symmetrically disposed on both sides of the U-shaped plate and a connecting plate connected to the two base plates.

[0031] Preferably, the U-shaped plate is connected to a first guide frame for guiding the first toothed plate and a second guide frame for guiding the second toothed plate.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The present invention, by setting up a U-shaped plate, a bottom closure, a movable plate, a top plate and a closed cover, forms a closed area in the unloading area, which surrounds the unloading area and prevents the material in the unloading area from being lifted out. When the U-shaped plate, bottom closure, movable plate, top plate and closed cover are all retracted, they will not interfere with the loading of materials in the hopper and the normal transportation of the vehicle body.

[0034] 2. By setting a first driving component, when the U-shaped plate is inside the vehicle body, the vehicle body presses on the upper end of the top plate, and the first spring is in a compressed state; when the U-shaped plate slides laterally outward, the vehicle body no longer presses on the upper end of the top plate, and the first spring needs to return to its original shape. One end of the swing plate moves upward with the top plate, and the other end of the swing plate moves laterally on the guide rod. The first spring gradually recovers its deformation, the top plate slides upward, and the moving plate and the top plate slide upward to surround the upper area of ​​the U-shaped plate. When the U-shaped plate slides outward, it pushes the cover to rotate, and the cover closes the area directly above the U-shaped plate.

[0035] 3. By setting a second driving component, when the top plate slides upward, the gear rotates and drives the second toothed plate to slide downward, thereby driving the bottom sealing component to slide downward until it contacts the ground. The bottom sealing component slides downward and contacts the ground, thus preventing material from escaping from the area below the U-shaped plate. Attached Figure Description

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figure 1-9, a dust suppression unloading device, comprising a vehicle body 1, wheels 5 provided at the bottom of the vehicle body 1, a material hopper 2 rotatably provided on the vehicle body 1, a first cylinder 21 provided on the vehicle body 1 and used to drive the material hopper 2 to rotate, and a closing cover 3 rotatably provided on the material hopper 2 and used to seal the material hopper 2. It further includes:

[0050] A dust suppression structure 4, provided at one end of the material hopper 2 close to the closing cover 3, which is used to form a closed space in the unloading area when the material hopper 2 rotates for unloading, surrounding the unloading area.

[0051] With such a design, before the material hopper 2 unloads, the dust suppression structure 4 forms a closed space in the unloading area. When unloading, the dust raised when the material is poured can be blocked by the dust suppression structure 4, preventing leakage, avoiding affecting the external environment, protecting the working environment of the staff, and avoiding waste of material resources.

[0052] In one embodiment, the dust suppression structure 4 includes:

[0053] A U-shaped plate 401, horizontally slidably provided on the vehicle body 1 and forming an "open" - shaped closed area together with the vehicle body 1 when sliding outwards. The vehicle body 1 is provided with a second chute 419 for the U-shaped plate 401 to slide;

[0054] A top plate 403, vertically slidably provided on the top of the U-shaped plate 401, sliding upwards when the U-shaped plate 401 slides outwards, and pushing the closing cover 3 to rotate when sliding upwards;

[0055] A bottom closure, vertically slidably provided at the bottom of the U-shaped plate 401, sliding to contact the ground;

[0056] A moving plate 416, provided above the U-shaped plate 401 and horizontally slidably provided on the vehicle body 1. The vehicle body 1 is provided with a first chute 417 for the moving plate 416 to slide;

[0057] A driving component, used to drive the U-shaped plate 401 and the moving plate 416 to slide horizontally, and drive the top plate 403 and the bottom closure to slide vertically.

[0058] This design ensures that when the U-shaped plate 401 slides outward, it surrounds the unloading area, and the bottom sealing member slides downward to contact the ground, preventing material from escaping from the area below the U-shaped plate 401. The moving plate 416 and the top plate 403 slide upward to surround the area above the U-shaped plate 401, and push the cover 3 to rotate when the U-shaped plate 401 slides outward, thus sealing the area directly above the U-shaped plate 401. The U-shaped plate 401, the bottom sealing member, the moving plate 416, the top plate 403, and the cover 3 together form a closed area in the unloading area, surrounding the unloading area and preventing material from being thrown up and escaping. When the U-shaped plate 401, the bottom sealing member, the moving plate 416, the top plate 403, and the cover 3 are all retracted, they will not interfere with the loading of materials in the hopper 2 or the normal transportation of the vehicle body 1.

[0059] In one embodiment, the driving component includes:

[0060] The second cylinder 421 is located in the second slide groove 419 and is used to drive the U-shaped plate 401 to slide laterally.

[0061] The second spring 420 is located in the first slide groove 417. The two sides of the cover 3 are connected to baffles 31 that limit the movement plate 416. When the cover 3 blocks the hopper 2, it is in a compressed state. When the cover 3 is opened, it returns to its original state and allows the movement plate 416 to slide laterally.

[0062] The first driving component is disposed on the U-shaped plate 401 and is used to drive the top plate 403 to slide vertically;

[0063] The second driving component is located on the U-shaped plate 401 and is used to drive the bottom closing component to slide vertically.

[0064] With this design, the second cylinder 421 is fixedly installed in the second slide groove 419; one end of the second spring 420 is fixedly connected to the first slide groove 417, and the other end is fixedly connected to the moving plate 416; the cover 3 is fixedly connected to the baffle 31.

[0065] In one embodiment, the first driving element includes:

[0066] Slider 411 is horizontally slidable on U-shaped plate 401;

[0067] The swing plate 410 is hinged at one end to the top plate 403 and at the other end to the slider 411;

[0068] The first spring 414 is vertically mounted on the U-shaped plate 401 and connected to the bottom end of the top plate 403;

[0069] When the second cylinder 421 drives the U-shaped plate 401 to slide laterally outward, the top plate 403 slides upward under the action of the first spring 414 and the swing plate 410.

[0070] In one embodiment, the U-shaped plate 401 is provided with a guide rod 409 for guiding the slider 411 when it slides, and the U-shaped plate 401 is provided with a first fixing block 412 for fixing the guide rod 409.

[0071] The bottom end of the top plate 403 is slidably provided with a guide post 413 to guide the first spring 414. The top plate 403 is sleeved on the guide post 413, the first spring 414 is sleeved on the guide post 413, and the bottom end of the guide post 413 is connected to a second fixing block 415.

[0072] With this design, the first fixing block 412 and the second fixing block 415 are both fixedly connected to the U-shaped plate 401; the guide rod 409 is fixedly connected to the first fixing block 412; and the slider 411 is slidably connected to the guide rod 409.

[0073] When the U-shaped plate 401 is inside the vehicle body 1, the vehicle body 1 presses against the upper end of the top plate 403, and the first spring 414 is in a compressed state. When the U-shaped plate 401 slides laterally outward, the vehicle body 1 no longer presses against the upper end of the top plate 403. Since the first spring 414 needs to return to its original state, one end of the swing plate 410 moves upward with the top plate 403, and the other end of the swing plate 410 moves laterally on the guide rod 409. The first spring 414 gradually recovers its deformation, and the top plate 403 slides upward.

[0074] In one embodiment, the second driving member includes:

[0075] The first toothed plate 405 is connected to the bottom end of the top plate 403;

[0076] Gear 406 is rotatably mounted on U-shaped plate 401 and meshes with first toothed plate 405;

[0077] The second toothed plate 407 is slidably disposed on the U-shaped plate 401, meshes with the gear 406 and is connected to the bottom closure.

[0078] With this design, when the top plate 403 slides upward, the gear 406 rotates and drives the second toothed plate 407 to slide downward, thereby causing the bottom closure to slide downward until it contacts the ground.

[0079] In one embodiment, the bottom closure includes a bottom plate 402 symmetrically disposed on both sides of the U-shaped plate 401 and a connecting plate 418 connected to the two bottom plates 402.

[0080] In one embodiment, a first guide frame 404 for guiding the first toothed plate 405 and a second guide frame 408 for guiding the second toothed plate 407 are connected to the U-shaped plate 401.

[0081] With this design, both the first guide frame 404 and the second guide frame 408 are fixedly connected to the U-shaped plate 401.

[0082] Working principle: When in use, before the material is unloaded from the hopper 2, the dust suppression structure 4 forms a closed space in the unloading area. During unloading, the material raised when it is poured is blocked by the dust suppression structure 4, preventing leakage and avoiding impact on the external environment. This protects the working environment of the staff and avoids waste of material resources.

[0083] When the U-shaped plate 401 slides outward, it surrounds the unloading area, and the bottom sealing member slides downward to contact the ground, preventing material from escaping from the area below the U-shaped plate 401. The moving plate 416 and the top plate 403 slide upward to surround the area above the U-shaped plate 401, and push the cover 3 to rotate when the U-shaped plate 401 slides outward, so that the cover 3 seals the area directly above the U-shaped plate 401. The U-shaped plate 401, the bottom sealing member, the moving plate 416, the top plate 403 and the cover 3 together form a closed area in the unloading area, surrounding the unloading area so that the material in the unloading area will not be thrown up and escape. When the U-shaped plate 401, the bottom sealing member, the moving plate 416, the top plate 403 and the cover 3 are all retracted, they will not interfere with the loading in the hopper 2 and the normal transportation of the vehicle body 1.
