Description

Technical Field

[0001] The invention relates to the field of tobacco shred storage, and in particular to a novel material covering vehicle for tobacco shreds. Background Art

[0002] my country's tobacco industry has a huge market, and the storage process requirements for tobacco are becoming more and more stringent. During the storage of tobacco, corresponding transportation equipment is needed to transport the tobacco. During the transportation process, a covering device is needed to keep the tobacco warm, moisturize it, and prevent dust.

[0003] The covering cloths of existing covering devices are mostly stacked or rolled. Although they are easy to operate and can be used quickly to cover the material, this structure has poor thermal insulation, moisture retention and dust prevention effects. It can only achieve the simplest protection function and is only suitable for some sunny weather and harsh application environments. In a more humid climate or rainy weather, the protection effect of this covering cloth is even worse, and the tobacco inside the covering device often gets damp, and this traditional covering method cannot be used. Based on this, we proposed a new type of tobacco covering vehicle. Summary of the invention

[0004] In order to solve the technical problem that in humid climate or rainy weather, the protective effect of the covering cloth is worse, the tobacco inside the covering device often gets damp, and the traditional covering method cannot be used, the present invention provides a new type of tobacco covering vehicle.

[0005] The present invention is implemented by the following technical scheme: a novel tobacco covering vehicle, comprising a transport vehicle and a covering mechanism, wherein the covering mechanism is composed of a reciprocating alternating protection component and an opening and closing covering component;

[0006] The reciprocating alternating protection assembly includes a support frame, the inner surface of the support frame is connected to a connecting rod, the connecting rod is connected to a working motor, and the surface of the rotating shaft at the top of the working motor is sleeved with a first chain belt; the first chain belt is sleeved on the surfaces of the first transmission shaft and the second transmission shaft, and the first chain belt drives the first transmission shaft and the second transmission shaft to rotate.

[0007] The first chain belt is connected to the second chain belt, the tail end of the second chain belt is connected to the first clamping block, the surface of the second chain belt is provided with raised clamping teeth, the second chain belt is clamped on the inner side of the first clamping block, and the second chain belt drives the first clamping block to move.

[0008] The reciprocating alternating protection assembly further includes a third transmission shaft, a fourth transmission shaft, a fifth transmission shaft and a sixth transmission shaft; the third transmission shaft and the fifth transmission shaft are connected by a third chain belt, the third chain belt and the fourth chain belt are connected together, and the top end of the fourth chain belt is connected to a second locking block;

[0009] The fifth conveyor chain belt is sleeved on the fourth conveyor shaft and the sixth conveyor shaft, and the top ends of the fifth conveyor chain belt and the third chain belt are connected with a third engaging block.

[0010] The two ends of the lower reciprocating switching plate are mounted on the connecting crossbeam, a set of side surfaces of the lower reciprocating switching plate are clamped in the interior of the sliding clamping groove, and another set of side surfaces of the lower reciprocating switching plate are clamped in the gap between the first clamping block and the second clamping block;

[0011] One side of the upper reciprocating switch plate is clamped in the gap in the third clamping block.

[0012] The opening and closing covering material assembly includes a mounting plate and a receiving block, the receiving block is connected to the top of the first mounting rod, the receiving block is connected to the moving frame, a moving groove is provided on the surface of the moving frame, and the bottom of the receiving block is clamped on the inner side of the moving groove; the first mounting rod is connected to the bottom of the upper reciprocating switching plate, and when the upper reciprocating switching plate moves, it drives the first mounting rod to move synchronously.

[0013] A receiving frame is installed on the outside of the receiving block, a slide groove is arranged on the surface of the receiving frame, a moving rod is passed through the inside of the slide groove, the moving rod is connected to the adjustment plate, the adjustment plate is passed through the moving groove rod, the adjustment plate is connected to the moving axis block, and the moving axis block is connected to the covering plate.

[0014] A receiving bracket is connected to the outer side of the first mounting rod, a first rack is connected to the top of the rod body of the receiving bracket, a rotating gear is meshed on the outer side of the first rack, a second rack is meshed on the side of the rotating gear away from the first rack, a movable rod is fixedly connected to the outer side of the second rack, and the movable rod is connected to the second mounting rod.

[0015] As a further improvement of the above solution, the opening and closing covering material assembly is installed above the lower reciprocating switching plate, and the upper reciprocating switching plate is located above the lower reciprocating switching plate. The lower reciprocating switching plate and the upper reciprocating switching plate are in the same straight line, and the upper reciprocating switching plate protects the opening and closing covering material assembly on the lower reciprocating switching plate. When encountering bad weather during outdoor transportation, the upper reciprocating switching plate can block rainwater to prevent the tobacco from being soaked by water.

[0016] As a further improvement of the above scheme, the shielding plates in the opening and closing shielding assembly cover the storage dish for storing tobacco shreds. The shielding plates are fan-shaped and are provided in four groups. When the four groups of shielding plates are closed, they form a circle covering the storage dish.

[0017] As a further improvement of the above scheme, the four groups of shielding plates are in a closed state, and the four groups of shielding plates form a circle covering the top of the storage dish to close the storage dish, ensure the sealing of the storage dish, and achieve better protection for the tobacco in the storage dish.

[0018] As a further improvement of the above scheme, the second rack drives the movable rod and the second mounting rod to move, and the second mounting rod then moves outward. As the second mounting rod moves, the two groups of material shielding plates on the other side are driven to move and expand outward synchronously. At this time, the material shielding plates lose their protection for the storage dish, making it convenient for the staff to take out the tobacco in the storage dish.

[0019] As a further improvement of the above scheme, by moving the upper reciprocating switching plate to the left and the lower reciprocating switching plate to the right, after the lower reciprocating switching plate moves to the right, the upper reciprocating switching plate no longer protects the lower reciprocating switching plate, thereby facilitating the removal and placement of tobacco from the storage dish inside the opening and closing material covering assembly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention innovatively combines the structure in the reciprocating alternating protection component with the opening and closing material covering component. When it is necessary to take out the tobacco, the upper reciprocating switching plate in the reciprocating alternating protection component moves horizontally to the left, and the lower reciprocating switching plate moves horizontally to the right. The synchronous horizontal movement of the two groups of reciprocating switching plates can be achieved simultaneously to ensure the continuity of the movement. In the process of the lower reciprocating switching plate moving horizontally to the right, the material covering plate in the opening and closing material covering component is also driven to open synchronously, so that the tobacco stored in the storage dish is exposed, which is convenient for the staff to take out the tobacco. Through the mutual linkage and cooperation of the two groups of mechanisms, the protection and removal of the tobacco can be quickly achieved, which is convenient for the workers to use.

[0022] 2. The present invention innovatively proposes a combination of a reciprocating alternating protection component and an opening and closing covering component. The lower reciprocating switching plate and the upper reciprocating switching plate in the reciprocating alternating protection component are in the same straight line, and the upper reciprocating switching plate protects the opening and closing covering component on the lower reciprocating switching plate to achieve the purpose of protection and waterproofing. Four groups of covering plates form a circular shape covering the top of the storage dish, closing the storage dish, ensuring the sealing of the storage dish, and achieving better protection of the tobacco.

[0037] Specifically, the first chain belt 34 is sleeved on the surfaces of the first transmission shaft 35 and the second transmission shaft 36 , and the first chain belt 34 drives the first transmission shaft 35 and the second transmission shaft 36 to rotate.

[0038] The first chain belt 34 and the second chain belt 37 are connected together, and the tail end of the second chain belt 37 is connected to the first locking block 38 .

[0040] Specifically, the reciprocating alternating protection assembly 3 further includes a third transmission shaft 39, a fourth transmission shaft 310, a fifth transmission shaft 311 and a sixth transmission shaft 312; the third transmission shaft 39 and the fifth transmission shaft 311 are connected by a third chain belt 393, the third chain belt 393 and the fourth chain belt 391 are connected together, and the top of the fourth chain belt 391 is connected to a second locking block 392;

[0041] The fifth conveying chain belt 313 is sleeved on the fourth conveying shaft 310 and the sixth conveying shaft 312 . The top ends of the fifth conveying chain belt 313 and the third chain belt 393 are connected with a third engaging block 314 .

[0042] Both ends of the lower reciprocating switch plate 317 are mounted on the connecting crossbeam 315, one set of side surfaces of the lower reciprocating switch plate 317 is clamped in the interior of the sliding clamping groove 316, and the other set of side surfaces of the lower reciprocating switch plate 317 is clamped in the gap between the first clamping block 38 and the second clamping block 392;

[0043] Specifically, through the operation of the working motor 33, the working motor 33 drives the first chain belt 34 to rotate synchronously, and the first chain belt 34 then drives the first transmission shaft 35 and the second transmission shaft 36 sleeved on the inner side thereof to rotate synchronously, and the first chain belt 34 then drives the first engaging block 38 connected to the top thereof to move synchronously, and the lower reciprocating switching plate 317 is engaged between the inner sides of the first engaging block 38 and the second engaging block 392, and the first engaging block 38 then drives the lower reciprocating switching plate 317 to move synchronously, and one side of the lower reciprocating switching plate 317 then moves on the inner side of the sliding slot 316;

[0044] As the lower reciprocating switching plate 317 moves, the second engaging block 392 engaged above the lower reciprocating switching plate 317 moves synchronously, and the second engaging block 392 then drives the fourth chain belt 391 connected thereto to move, and the fourth chain belt 391 drives the third transmission shaft 39 and the fifth transmission shaft 311 to rotate synchronously, and the third engaging block 314 connected to the top of the fifth transmission shaft 311 moves synchronously, and the third engaging block 314 drives the inner side connected thereto. At this time, after the above process, the upper reciprocating switching plate 318 moves to the left, and the lower reciprocating switching plate 317 moves to the right ( Figure 2 As shown in the state, after the lower reciprocating switching plate 317 moves to the right, the upper reciprocating switching plate 318 no longer protects the lower reciprocating switching plate 317, making it convenient to take and put the tobacco in the storage dish 5 inside the opening and closing covering assembly 4.

[0045] One side of the upper reciprocating switch plate 318 is engaged in the gap in the third engaging block 314 .

[0046] Specifically, the opening and closing covering assembly 4 is installed above the lower reciprocating switching plate 317, and the upper reciprocating switching plate 318 is located above the lower reciprocating switching plate 317. The lower reciprocating switching plate 317 and the upper reciprocating switching plate 318 are in the same straight line, and the upper reciprocating switching plate 318 protects the opening and closing covering assembly 4 on the lower reciprocating switching plate 317. When the tobacco is transported outdoors in bad weather, the upper reciprocating switching plate 318 can block rainwater to prevent the tobacco from being soaked by water.

[0047] The opening and closing covering material assembly 4 includes a mounting plate 41 and a receiving block 43. The receiving block 43 is connected to the top of the first mounting rod 42. The receiving block 43 is connected to the moving frame 44. A moving groove 45 is provided on the surface of the moving frame 44. The bottom of the receiving block 43 is clamped on the inner side of the moving groove 45. The first mounting rod 42 is connected to the bottom of the upper reciprocating switching plate 318. When the upper reciprocating switching plate 318 moves, it drives the first mounting rod 42 to move synchronously.

[0048] A receiving frame 46 is installed on the outer side of the receiving block 43, and a slide groove 47 is arranged on the surface of the receiving frame 46. A moving rod 48 is passed through the inner side of the slide groove 47. The moving rod 48 is connected to the adjustment plate 49. The adjustment plate 49 is passed through the moving groove rod 410. The adjustment plate 49 is connected to the moving axis block 411, and the moving axis block 411 is connected to the covering plate 412.

[0049] The outer side of the first mounting rod 42 is connected to a receiving bracket 413, the top of the rod body of the receiving bracket 413 is connected to a first rack 414, the outer side of the first rack 414 is meshed with a rotating gear 415, the side of the rotating gear 415 away from the first rack 414 is meshed with a second rack 416, the outer side of the second rack 416 is fixedly connected to a movable rod 417, and the movable rod 417 is connected to the second mounting rod 418;

[0050] When the upper reciprocating switching plate 318 moves to the left, the upper reciprocating switching plate 318 drives the first mounting rod 42 connected thereto to move horizontally to the left, and the receiving block 43 connected to the bottom end of the first mounting rod 42 moves synchronously, and the receiving block 43 then moves horizontally on the moving frame 44, and the receiving frame 46 connected to the outside of the receiving block 43 moves synchronously, and the slide groove 47 provided on the surface of the receiving frame 46 drives the moving rod 48 to move synchronously, and the moving rod 48 drives the adjusting plate 49 to move synchronously, and the adjusting plate 49 drives the moving axis block 411 connected thereto to move synchronously, and the moving axis block 411 moves outward, and the moving axis block 411 then drives the material shielding plate 412 connected thereto to move, and the two groups of material shielding plates 412 on this side move and expand outward;

[0051] While the first mounting rod 42 moves outward, the first mounting rod 42 drives the receiving bracket 413 connected thereto to move synchronously, and the first rack 414 connected to the receiving bracket 413 moves synchronously, and the first rack 414 drives the rotating gear 415 to rotate, and the rotating gear 415 then drives the second rack 416 meshing therewith to move outward, and the second rack 416 then drives the movable rod 417 and the second mounting rod 418 to move, and the second mounting rod 418 then moves outward. With the movement of the second mounting rod 418, the two groups of material shielding plates 412 on the other side are driven to move and expand outward synchronously. At this time, the material shielding plate 412 loses its protection to the storage dish 5, making it convenient for the staff to take out the tobacco in the storage dish 5.

[0052] As a further technical effect, the reciprocating alternating protection component 3 is combined with the structure in the opening and closing covering component 4. When it is necessary to take out the tobacco, the upper reciprocating switching plate 318 in the reciprocating alternating protection component 3 moves horizontally to the left, and the lower reciprocating switching plate 317 moves horizontally to the right. The two groups of reciprocating switching plates can be synchronously moved horizontally to ensure the continuity of the movement. In the process of the lower reciprocating switching plate 317 moving horizontally to the right, the covering plate 412 in the opening and closing covering component 4 is also synchronously driven to open, so that the tobacco stored in the storage dish 5 is exposed, making it convenient for the staff to take out the tobacco.

[0053] Specifically, the shielding plates 412 in the opening and closing shielding assembly 4 cover the storage dish 5 for storing tobacco shreds. The shielding plates 412 are fan-shaped and are provided in four groups. When the four groups of shielding plates 412 are closed, they form a circle covering the storage dish 5. The four groups of shielding plates 412 are in a closed state, and the four groups of shielding plates 412 form a circular shape covering the top of the storage dish 5, closing the storage dish 5, ensuring the sealing of the storage dish 5, and realizing better protection of the tobacco shreds in the storage dish 5.

[0054] The specific implementation steps of the overall technical solution of the present invention are as follows:

[0055] When in use, the tobacco is placed in the storage dish 5 for storage and transportation. When it is necessary to transport, the tobacco in the storage dish 5 is driven to be transported by pushing the transport vehicle 1. At the same time, when the present invention is in the transporting state, the lower reciprocating switching plate 317 and the upper reciprocating switching plate 318 are in the same straight line, and the upper reciprocating switching plate 318 protects the opening and closing shielding component 4 on the lower reciprocating switching plate 317. When outdoor transportation encounters bad weather, the upper reciprocating switching plate 318 can block rainwater to prevent the tobacco from being soaked by water. At the same time, the four groups of shielding plates 412 are in a closed state, and the four groups of shielding plates 412 form a circular cover above the storage dish 5, closing the storage dish 5, ensuring the sealing of the storage dish 5, and achieving better protection for the tobacco in the storage dish 5.

[0056] When the tobacco is transported to a designated location and needs to be taken out, the working motor 33 drives the first chain belt 34 to rotate synchronously, and the first chain belt 34 then drives the first transmission shaft 35 and the second transmission shaft 36 sleeved on its inner side to rotate synchronously, and the first chain belt 34 then drives the first engaging block 38 connected to its top end to move synchronously, and a lower reciprocating switching plate 317 is engaged between the inner sides of the first engaging block 38 and the second engaging block 392, and the first engaging block 38 then drives the lower reciprocating switching plate 317 to move synchronously, and one side of the lower reciprocating switching plate 317 then moves on the inner side of the sliding slot 316;

[0057] As the lower reciprocating switching plate 317 moves, the second engaging block 392 engaged above the lower reciprocating switching plate 317 moves synchronously, and the second engaging block 392 then drives the fourth chain belt 391 connected thereto to move, and the fourth chain belt 391 drives the third transmission shaft 39 and the fifth transmission shaft 311 to rotate synchronously, and the third engaging block 314 connected to the top of the fifth transmission shaft 311 moves synchronously, and the third engaging block 314 drives the inner side connected thereto. At this time, after the above process, the upper reciprocating switching plate 318 moves to the left, and the lower reciprocating switching plate 317 moves to the right ( Figure 2 status shown);

[0058] After the lower reciprocating switching plate 317 moves to the right side, the upper reciprocating switching plate 318 no longer protects the lower reciprocating switching plate 317. At the same time, in the above process, when the upper reciprocating switching plate 318 moves to the left side, the upper reciprocating switching plate 318 drives the first mounting rod 42 connected thereto to move horizontally to the left side, and the receiving block 43 connected to the bottom end of the first mounting rod 42 moves synchronously, and the receiving block 43 then moves horizontally on the moving frame 44, and the receiving frame 46 connected to the outside of the receiving block 43 moves synchronously, and the slide groove 47 on the surface of the receiving frame 46 drives the moving rod 48 to move synchronously, and the moving rod 48 drives the adjusting plate 49 to move synchronously, and the adjusting plate 49 drives the moving axis block 411 connected thereto to move synchronously, and the moving axis block 411 moves outward, and the moving axis block 411 then drives the material shielding plate 412 connected thereto to move, and the two sets of material shielding plates 412 on this side move and expand outward;

[0059] At the same time, when the first mounting rod 42 moves outward, the first mounting rod 42 drives the receiving bracket 413 connected thereto to move synchronously, and the first rack 414 connected to the receiving bracket 413 moves synchronously, and the first rack 414 drives the rotating gear 415 to rotate, and the rotating gear 415 then drives the second rack 416 meshing therewith to move outward, and the second rack 416 then drives the movable rod 417 and the second mounting rod 418 to move, and the second mounting rod 418 then moves outward. With the movement of the second mounting rod 418, the two groups of material shielding plates 412 on the other side are driven to move and expand outward synchronously. At this time, the material shielding plate 412 loses its protection to the storage dish 5, making it convenient for the staff to take out the tobacco in the storage dish 5.

[0060] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
