Abstract
Description
Technical Field
[0001] The invention relates to the technical field of wood chip transportation, and in particular to an automatic hopper loading mechanism. Background Art
[0002] The hopper in the prior art is generally a single loading and unloading form, where wood chips are placed in the hopper. When the wood chips in the hopper need to be transported, the transport vehicle is moved below the discharge port of the hopper, and the wood chips are transported to the transport vehicle through the discharge port, thereby completing the unloading of the hopper.
[0003] At present, when a large hopper is in use, wood chips need to be placed in the hopper. After the wood chips enter the hopper, the long-term accumulation and mutual squeezing of the wood chips will cause the wood chips to ferment and decay. Therefore, an automatic hopper loading mechanism is proposed to automatically adjust the ventilation effect in the hopper according to the amount of wood chips in the hopper, so as to prevent the wood chips from rotting due to long-term accumulation and squeezing. Summary of the invention
[0004] In view of the problems in the prior art, the present invention provides an automatic hopper loading mechanism, which is convenient for automatically adjusting the ventilation effect in the hopper according to the amount of wood chips in the hopper.
[0005] The technical solution adopted by the present invention to solve its technical problem is an automated hopper loading mechanism, comprising a square storage frame with an opening facing upward, a plurality of groups of discharge hoppers being provided on the lower surface of the storage frame, the discharge hoppers being funnel-shaped and connected to the interior of the storage frame, the bottoms of the plurality of groups of discharge hoppers being hinged with baffles via electric hinges, a first ventilation structure being provided on the outer side of the discharge hoppers, a plurality of groups of second ventilation structures being provided on the outer side of the storage frame, a driving structure being provided on the outer side of the discharge hopper, and the driving structure being used to open the second ventilation structure.
[0006] By adopting the above technical solution, wood chips are placed in the storage frame. After the wood chips enter the storage frame, they fall into several groups of discharge hoppers. When the amount of wood chips in the discharge hopper reaches a certain amount, the first ventilation structure is driven to work by the extrusion of the wood chips. The first ventilation structure can improve the ventilation effect in the discharge hopper and prevent the wood chips from piling up and fermenting.
[0007] When there are more wood chips in the storage frame, the extrusion force on the wood chips in the discharge hopper will be greater. When the wood chips reach a certain amount, the extrusion drive structure will work. When the drive structure works, it drives the second ventilation structure to work. When the second ventilation structure works, it can improve the ventilation effect in the storage frame, further preventing the wood chips from accumulating in the storage frame and causing fermentation.
[0008] When it is necessary to transport the wood chips in the storage frame, the transport vehicle is moved to the bottom of the discharge hopper, and the carriage is located under the two groups of discharge hoppers. The baffle is driven by the electric hinge to swing. At this time, the baffle no longer blocks the bottom of the discharge hopper, and the wood chips enter the carriage through the bottom of the discharge hopper. When the wood chips in the carriage reach a certain amount, the baffle is driven by the electric hinge to swing again, and the corresponding discharge hopper is closed, so as to facilitate the control of the discharge hopper for unloading;
[0009] It should be pointed out that the plurality of groups of discharge hoppers described in the present invention are four groups of discharge hoppers arranged in an array, which can simultaneously load two groups of transport vehicles, thereby further improving the loading efficiency.
[0010] Specifically, the first ventilation structure includes a first wear-resistant plate detachably mounted on the inner wall of the discharge hopper, an inclined extrusion plate is provided on the outer side of the discharge hopper, a plurality of groups of slide bars are fixedly connected to the side of the extrusion plate close to the discharge hopper, one end of the slide bar passes through the discharge hopper and is slidably connected to the discharge hopper, an end of the slide bar away from the extrusion plate is fixedly connected to an extrusion block, an extrusion groove corresponding to the extrusion block is provided on the first wear-resistant plate, and the extrusion block is located in the extrusion groove and is slidably connected to the extrusion groove;
[0011] The outer side of the discharge hopper is provided with a plurality of groups of first conical grooves penetrating therethrough, the first wear-resistant plate is provided with a plurality of groups of second conical grooves penetrating therethrough, the first conical grooves correspond to the second conical grooves, the size of the first conical grooves is larger than the second conical grooves, and the side of the extrusion plate close to the discharge hopper is provided with a plurality of groups of conical sealing blocks, the conical sealing blocks are initially located in the first conical grooves and the second conical grooves;
[0012] An inclined fixing plate is provided on the outside of the discharge hopper, and the fixing plate is fixedly connected to the outside of the discharge hopper through a support rod. A plurality of groups of first springs are fixedly connected between the fixing plate and the side of the extrusion plate away from the discharge hopper.
[0013] By adopting the above technical solution, when the wood chips in the discharge hopper reach a certain amount, the extrusion block is driven to move by the extrusion of the wood chips, and the extrusion block drives the sliding rod and the extrusion plate to move synchronously when the extrusion block moves, and the extrusion plate drives the conical sealing block to move when the extrusion plate moves, and at the same time squeezes the first spring to store force. After the conical sealing block moves, the conical sealing block no longer blocks the first conical groove and the second conical groove, and air enters the discharge hopper through the first conical groove and the second conical groove. At the same time, the discharge hopper can be ventilated by relying on the storage frame with an upward opening;
[0014] The more wood chips there are in the storage frame, the greater the extrusion force on the extrusion block. At the same time, the extrusion block will further drive the slide bar and the extrusion plate to move. When the extrusion plate moves to a certain position, the conical sealing block is completely separated from the first conical groove and the second conical groove, so that the ventilation effect in the discharge hopper can be further improved, so that the ventilation efficiency can be automatically adjusted according to the amount of wood chips in the storage frame and the discharge hopper.
[0015] When the wood chips in the discharge hopper are discharged, the resetting effect of the first spring drives the extrusion plate to reset and move, and the extrusion plate drives the slide bar and the extrusion block to move synchronously when resetting and moving. The extrusion plate drives the conical sealing block to move, and the movement of the conical sealing block can push the wood chips in the first conical groove and the second conical groove back into the discharge hopper for cleaning to prevent them from being blocked in the first conical groove and the second conical groove. When the conical sealing block moves to a certain position, it blocks the first conical groove and the second conical groove again, so that the extrusion plate returns to its initial state, which is convenient for storing the next batch of wood chips, and the ventilation efficiency is automatically adjusted according to the storage amount.
[0016] Specifically, the driving structure includes a liquid storage pad installed on the side of the fixed plate close to the first spring, the liquid storage pad is in extrusion contact with the extrusion plate, and a liquid outlet joint is provided on the side of the fixed plate away from the liquid storage pad, one end of the liquid outlet joint is connected to the interior of the liquid storage pad, and the other end of the liquid outlet joint is connected to the second ventilation structure through a pipeline.
[0017] By adopting the above technical solution, when the wood chips in the discharge hopper reach a certain amount, the wood chips are accumulated in the storage frame. The weight of the wood chips accumulated in the storage frame can further drive the extrusion block to move. When the extrusion block moves, it relies on the sliding rod to drive the extrusion plate to move. When the extrusion plate moves, it squeezes the liquid storage pad. When the liquid storage pad is squeezed, it drives the second ventilation structure to work, so as to facilitate ventilation in the storage frame, thereby automatically adjusting the ventilation efficiency of the second ventilation structure according to the amount of wood chips in the storage frame.
[0018] Specifically, the second ventilation structure includes a plurality of groups of vertically arranged moving plates, the moving plates are located outside the material storage frame, a side of the moving plate close to the material storage frame is provided with a slot, an expansion pad is fixedly connected in the slot, a side of the moving plate close to the material storage frame is fixedly connected to a second spring, and an end of the second spring away from the moving plate is fixedly connected to the outside of the material storage frame;
[0019] The inner wall of the material storage frame is detachably connected with a plurality of groups of second wear-resistant plates, the material storage frame is provided with a plurality of groups of first vent holes arranged obliquely, the second wear-resistant plate is provided with a plurality of groups of second vent holes corresponding to the first vent holes, and a side of the movable plate close to the material storage frame is provided with a plurality of groups of sealing rods arranged obliquely, the sealing rods are located in the first vent holes and the second vent holes and are slidably connected with the first vent holes and the second vent holes;
[0020] The liquid outlet joint is communicated with the expansion pad in the lowermost movable plate through a pipeline, and adjacent expansion pads are communicated with each other through pipelines.
[0021] By adopting the above technical scheme, the weight of the wood chips accumulated in the material storage frame can be further used to drive the extrusion block to move. When the extrusion block moves, the sliding rod drives the extrusion plate to move. When the extrusion plate moves, it squeezes the liquid storage pad, and the liquid outlet joint is used to communicate with the expansion pad in the movable plate at the bottom, thereby driving the expansion pad to expand. When the expansion pad expands, it squeezes the movable plate to move outward and drives the second spring to store force. When the movable plate moves outward, it drives the sealing rod to separate from the first ventilation hole and the second ventilation hole. When the movable plate moves outward to a certain position, the sealing rod separates from the first ventilation hole and the second ventilation hole and no longer blocks them. Air enters the material storage frame through the first ventilation hole and the second ventilation hole, thereby improving the ventilation effect in the material storage frame.
[0022] As the number of wood chips in the storage frame increases, the squeezing force on the squeezing plate increases. When the expansion pad in the bottom movable plate expands to the limit, the expansion pads in the upper movable plate are driven to expand through the communication between adjacent expansion pads, and the corresponding first ventilation holes and second ventilation holes are opened, so as to automatically adjust the ventilation efficiency of the storage frame according to the amount of wood chips in the storage frame.
[0023] When the wood chips in the storage frame are discharged, the squeezing force on the squeezing block is reduced, and the liquid storage pad is no longer squeezed. The movable plate is driven to reset and move by relying on the reset effect of the second spring, and the expansion pad is squeezed at the same time, so that the liquid in the expansion pad is transported to the liquid storage pad through the pipeline again. When the second spring drives the movable plate to reset and move to a certain position, the sealing rod is inserted into the first ventilation hole and the second ventilation hole again, and the first ventilation hole and the second ventilation hole can be cleaned by relying on the reset movement of the sealing rod. When the sealing rod moves to a certain position, the sealing rod blocks the first ventilation hole and the second ventilation hole again, and the movable plate returns to its initial state.
[0024] Specifically, the elastic forces of the second springs on adjacent moving plates are different, and the elastic coefficients of the second springs on adjacent moving plates gradually increase from bottom to top.
[0025] By adopting the above technical solution, relying on the different elastic coefficients of the second spring, the movable plate of the corresponding height can be automatically driven to move according to the amount of wood chips in the storage frame, thereby opening the corresponding ventilation position;
[0026] When the movable plate at the bottom moves to the limit, the liquid in the expansion pad in the lowest movable plate will enter the expansion pad in another group of movable plates at the top through the pipeline, thereby driving the other group of expansion pads to expand and further improving the ventilation efficiency in the storage frame, thereby improving the movement stability of several groups of movable plates.
[0027] Specifically, a vibration motor is disposed on the outer sides of the plurality of groups of discharge hoppers.
[0028] By adopting the above technical solution, when it is necessary to discharge the wood chips in the storage frame and the discharge hopper, the baffle is driven by the electric hinge to swing, thereby opening the discharge hopper, and the wood chips enter the transport vehicle compartment through the discharge hopper. At the same time, the vibration motor is turned on, which can further improve the convenience of unloading and prevent the wood chips from piling up for a long time, causing difficulty in unloading.
[0029] Specifically, a maintenance platform is provided on the outside of the material storage frame, a fence is provided on the outside of the maintenance platform, and a maintenance staircase is provided on the outside of the material storage frame.
[0030] By adopting the above technical solution, the staff can carry out maintenance and repair of the whole by relying on the maintenance platform and maintenance stairs.
[0031] Specifically, a horizontally arranged mounting rod is provided below the material storage frame, a plurality of groups of supporting legs are fixedly connected below the mounting rod, and the lower ends of the supporting legs are fixedly connected with universal casters.
[0032] By adopting the above technical solution, the entire device can be easily driven to move by relying on the supporting legs and universal casters, thereby improving the overall mobility convenience.
[0033] Specifically, the corners of the material storage frame are fixedly connected with reinforcing ribs.
[0034] By adopting the above technical solution, the overall stability of the material storage frame can be improved by relying on the reinforcing ribs, and the material storage frame can be prevented from being deformed.
[0035] Beneficial effects of the present invention:
[0036] (1) The automatic hopper loading mechanism described in the present invention, when the wood chips in the discharge hopper reach a certain amount, the extrusion block is driven to move by the extrusion of the wood chips, and the extrusion plate drives the conical sealing block to move when it moves. After the conical sealing block moves, the conical sealing block no longer blocks the first conical groove and the second conical groove, and air enters the discharge hopper through the first conical groove and the second conical groove. At the same time, the discharge hopper can be ventilated by relying on the storage frame with an upward opening; the more wood chips in the storage frame, the greater the extrusion force on the extrusion block, thereby further improving the ventilation effect in the discharge hopper, thereby facilitating automatic adjustment of the ventilation efficiency according to the amount of wood chips in the storage frame and the discharge hopper.
[0037] (2) The automatic hopper loading mechanism described in the present invention can further drive the extrusion block to move by relying on the weight of the wood chips accumulated in the storage frame. When the extrusion block moves, it drives the extrusion plate to move. When the extrusion plate moves, it squeezes the liquid storage pad, thereby driving the expansion pad to expand. When the expansion pad expands, it squeezes the movable plate to move outward and drives the sealing rod to separate from the first ventilation hole and the second ventilation hole. When the movable plate moves outward to a certain position, the sealing rod separates from the first ventilation hole and the second ventilation hole and no longer blocks them. Air enters the storage frame through the first ventilation hole and the second ventilation hole, thereby improving the ventilation effect in the storage frame, thereby facilitating automatic adjustment of the ventilation efficiency of the storage frame according to the amount of wood chips in the storage frame.

DETAILED DESCRIPTION
[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0052] In order to automatically adjust the ventilation effect in the hopper according to the amount of wood chips in the hopper, for example, Figure 1 , Figure 2 , Figure 3 As shown, an automatic hopper loading mechanism described in the present invention comprises a square storage frame 1 with an opening facing upward, a plurality of groups of discharge hoppers 2 are provided on the lower surface of the storage frame 1, the discharge hoppers 2 are funnel-shaped, and the discharge hoppers 2 are connected to the inside of the storage frame 1, and the bottoms of the plurality of groups of the discharge hoppers 2 are hinged with baffles 3 through electric hinges, a first ventilation structure is provided on the outer side of the discharge hoppers 2, a plurality of groups of second ventilation structures are provided on the outer side of the storage frame 1, and a driving structure is provided on the outer side of the discharge hopper 2, and the driving structure is used to open the second ventilation structure.
[0053] When in use, wood chips are put into the storage frame 1. After the wood chips enter the storage frame 1, they fall into a plurality of groups of discharge hoppers 2. When the amount of wood chips in the discharge hopper 2 reaches a certain amount, the first ventilation structure is driven to work by squeezing the wood chips. The first ventilation structure can improve the ventilation effect in the discharge hopper 2 to prevent the wood chips from piling up and fermenting.
[0054] When there are more wood chips in the storage frame 1, the extrusion force on the wood chips in the discharge hopper 2 will be greater. When the wood chips reach a certain amount, the extrusion drive structure will work. When the drive structure works, it drives the second ventilation structure to work. When the second ventilation structure works, it can improve the ventilation effect in the storage frame 1, and further prevent the wood chips from accumulating in the storage frame 1 and causing fermentation.
[0055] When it is necessary to transport the wood chips in the storage frame 1, the transport vehicle is moved to the bottom of the discharge hopper 2, and the carriage is located under the two groups of discharge hoppers 2. The baffle 3 is driven by the electric hinge to swing. At this time, the baffle 3 no longer blocks the bottom of the discharge hopper 2, and the wood chips enter the carriage through the bottom of the discharge hopper 2. When the wood chips in the carriage reach a certain amount, the baffle 3 is driven by the electric hinge to swing again, and the corresponding discharge hopper 2 is closed, so that it is convenient to control the discharge hopper 2 to discharge materials;
[0056] It should be pointed out that the plurality of groups of discharge hoppers 2 described in the present invention are four groups of discharge hoppers 2 arranged in an array, which can simultaneously load two groups of transport vehicles, thereby further improving the loading efficiency.
[0057] In order to automatically adjust the ventilation efficiency according to the amount of wood chips in the storage frame 1 and the discharge hopper 2, for example, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention also includes that the first ventilation structure includes a first wear-resistant plate 4 detachably mounted on the inner wall of the discharge hopper 2, an inclined extrusion plate 5 is provided on the outer side of the discharge hopper 2, a plurality of groups of slide bars 6 are fixedly connected to the side of the extrusion plate 5 close to the discharge hopper 2, one end of the slide bar 6 passes through the discharge hopper 2 and is slidably connected to the discharge hopper 2, an end of the slide bar 6 away from the extrusion plate 5 is fixedly connected to an extrusion block 7, an extrusion groove 8 corresponding to the extrusion block 7 is provided on the first wear-resistant plate 4, and the extrusion block 7 is located in the extrusion groove 8 and is slidably connected to the extrusion groove 8;
[0058] The outer side of the discharge hopper 2 is provided with a plurality of groups of first conical grooves 9 penetrating therethrough, the first wear-resistant plate 4 is provided with a plurality of groups of second conical grooves 10 penetrating therethrough, the first conical grooves 9 correspond to the second conical grooves 10, the size of the first conical grooves 9 is larger than the second conical grooves 10, and the side of the extrusion plate 5 close to the discharge hopper 2 is provided with a plurality of groups of conical sealing blocks 11, the conical sealing blocks 11 are initially located in the first conical grooves 9 and the second conical grooves 10;
[0059] The outer side of the discharge hopper 2 is provided with an inclined fixed plate 12, and the fixed plate 12 is fixedly connected to the outer side of the discharge hopper 2 through a support rod 13. A plurality of groups of first springs 14 are fixedly connected between the side of the extrusion plate 5 away from the discharge hopper 2 and the fixed plate 12.
[0060] When in use, when the wood chips in the discharge hopper 2 reach a certain amount, the extrusion block 7 is driven to move by the extrusion of the wood chips, and the extrusion block 7 drives the slide bar 6 and the extrusion plate 5 to move synchronously when moving, and the extrusion plate 5 drives the conical sealing block 11 to move when moving, and at the same time squeezes the first spring 14 to store force, and after the conical sealing block 11 moves, the conical sealing block 11 no longer blocks the first conical groove 9 and the second conical groove 10, and the air enters the discharge hopper 2 through the first conical groove 9 and the second conical groove 10, and at the same time, the discharge hopper 2 can be ventilated by relying on the storage frame 1 with an upward opening;
[0061] The more wood chips there are in the storage frame 1, the greater the extrusion force on the extrusion block 7. At the same time, the extrusion block 7 will further drive the slide bar 6 and the extrusion plate 5 to move. When the extrusion plate 5 moves to a certain position, the conical sealing block 11 is completely separated from the first conical groove 9 and the second conical groove 10, so that the ventilation effect in the discharge hopper 2 can be further improved, so that the ventilation efficiency can be automatically adjusted according to the amount of wood chips in the storage frame 1 and the discharge hopper 2.
[0062] After the wood chips in the discharge hopper 2 are discharged, the extrusion plate 5 is driven to reset and move by relying on the reset effect of the first spring 14. When the extrusion plate 5 resets and moves, the slide bar 6 and the extrusion block 7 are driven to move synchronously. When the extrusion plate 5 resets and moves, the conical sealing block 11 is driven to move. Relying on the movement of the conical sealing block 11, the wood chips in the first conical groove 9 and the second conical groove 10 can be pushed back into the discharge hopper 2, so as to be cleaned and prevented from being blocked in the first conical groove 9 and the second conical groove 10. When the conical sealing block 11 moves to a certain position, the first conical groove 9 and the second conical groove 10 are blocked again, so that the extrusion plate 5 is restored to its initial state, which is convenient for storing the next batch of wood chips, and the ventilation efficiency is automatically adjusted according to the storage amount.
[0063] For example, Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes that the driving structure includes a liquid storage pad 15 installed on the side of the fixed plate 12 close to the first spring 14, the liquid storage pad 15 is in extrusion contact with the extrusion plate 5, and a liquid outlet joint 16 is provided on the side of the fixed plate 12 away from the liquid storage pad 15, one end of the liquid outlet joint 16 is connected to the inside of the liquid storage pad 15, and the other end of the liquid outlet joint 16 is connected to the second ventilation structure through a pipeline.
[0064] During use, when the wood chips in the discharge hopper 2 reach a certain amount, the wood chips are accumulated in the storage frame 1, and the weight of the wood chips accumulated in the storage frame 1 can further drive the extrusion block 7 to move. When the extrusion block 7 moves, the slide bar 6 drives the extrusion plate 5 to move. When the extrusion plate 5 moves, it squeezes the liquid storage pad 15. When the liquid storage pad 15 is squeezed, it drives the second ventilation structure to work, so as to facilitate ventilation in the storage frame 1, thereby automatically adjusting the ventilation efficiency of the second ventilation structure according to the amount of wood chips in the storage frame 1.
[0065] In order to automatically adjust the ventilation efficiency of the material storage frame 1, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the present invention also includes that the second ventilation structure includes a plurality of groups of vertically arranged moving plates 17, the moving plates 17 are located outside the material storage frame 1, a side of the moving plate 17 close to the material storage frame 1 is provided with a slot 18, an expansion pad 19 is fixedly connected in the slot 18, a side of the moving plate 17 close to the material storage frame 1 is fixedly connected to a second spring 20, and an end of the second spring 20 away from the moving plate 17 is fixedly connected to the outside of the material storage frame 1;
[0066] The inner wall of the material storage frame 1 is detachably connected with a plurality of groups of second wear-resistant plates 21, the material storage frame 1 is provided with a plurality of groups of first ventilating holes 22 arranged obliquely, the second wear-resistant plates 21 are provided with a plurality of groups of second ventilating holes 23 corresponding to the first ventilating holes 22, and the side of the movable plate 17 close to the material storage frame 1 is provided with a plurality of groups of sealing rods 24 arranged obliquely, the sealing rods 24 are located in the first ventilating holes 22 and the second ventilating holes 23 and are slidably connected with the first ventilating holes 22 and the second ventilating holes 23;
[0067] The liquid outlet joint 16 is connected to the expansion pad 19 located in the lowermost movable plate 17 through a pipeline, and adjacent expansion pads 19 are connected through pipelines.
[0068] When in use, the weight of the wood chips accumulated in the material storage frame 1 can further drive the extrusion block 7 to move. When the extrusion block 7 moves, the sliding rod 6 drives the extrusion plate 5 to move. When the extrusion plate 5 moves, the liquid storage pad 15 is squeezed, and the liquid outlet joint 16 is connected with the expansion pad 19 in the movable plate 17 at the bottom, thereby driving the expansion pad 19 to expand. When the expansion pad 19 expands, the movable plate 17 is squeezed to move outwards and the second spring 20 is driven to store force. When the movable plate 17 moves outwards, the sealing rod 24 is driven to disengage from the first ventilation hole 22 and the second ventilation hole 23. When the movable plate 17 moves outwards to a certain position, the sealing rod 24 is disengaged from the first ventilation hole 22 and the second ventilation hole 23 and no longer blocks them. Air enters the material storage frame 1 through the first ventilation hole 22 and the second ventilation hole 23, thereby improving the ventilation effect in the material storage frame 1.
[0069] As the number of wood chips in the storage frame 1 increases, the squeezing force on the squeezing plate 5 increases. When the expansion pad 19 in the bottom movable plate 17 expands to the limit, the expansion pad 19 in the upper movable plate 17 is driven to expand through the communication between adjacent expansion pads 19, and the corresponding first ventilation holes 22 and second ventilation holes 23 are opened, so as to automatically adjust the ventilation efficiency of the storage frame 1 according to the amount of wood chips in the storage frame 1.
[0070] When the wood chips in the storage frame 1 are discharged, the squeezing force on the squeezing block 7 is reduced, and the liquid storage pad 15 is no longer squeezed. The movable plate 17 is reset and moved by relying on the reset effect of the second spring 20, and the expansion pad 19 is squeezed at the same time, so that the liquid in the expansion pad 19 is transported to the liquid storage pad 15 through the pipeline again. When the second spring 20 drives the movable plate 17 to reset and move to a certain position, the sealing rod 24 is inserted into the first ventilation hole 22 and the second ventilation hole 23 again, and the first ventilation hole 22 and the second ventilation hole 23 can be cleaned by relying on the reset movement of the sealing rod 24. When the sealing rod 24 moves to a certain position, the sealing rod 24 blocks the first ventilation hole 22 and the second ventilation hole 23 again, and the movable plate 17 returns to its initial state.
[0071] Exemplarily, the present invention also includes that the second springs 20 on adjacent moving plates 17 have different elastic forces, and the elastic coefficients of the second springs 20 on adjacent moving plates 17 gradually increase from bottom to top.
[0072] When in use, depending on the different elastic coefficients of the second spring 20, the movable plate 17 of the corresponding height can be automatically driven to move according to the amount of wood chips in the storage frame 1, thereby opening the corresponding ventilation position;
[0073] When the movable plate 17 at the bottom moves to the limit, the liquid in the expansion pad 19 in the lowest movable plate 17 will enter the expansion pad 19 in another group of movable plates 17 above through the pipeline, thereby driving the other group of expansion pads 19 to expand and further improving the ventilation efficiency in the storage frame 1, thereby improving the movement stability of several groups of movable plates 17.
[0074] For example, Figure 2 As shown, the present invention also includes that the outer sides of several groups of the discharge hoppers 2 are each provided with a vibration motor 25 .
[0075] During use, when it is necessary to discharge the wood chips in the storage frame 1 and the discharge hopper 2, the baffle 3 is driven by the electric hinge to swing, thereby opening the discharge hopper 2, and the wood chips enter the transport vehicle compartment through the discharge hopper 2. At the same time, the vibration motor 25 is turned on to further improve the convenience of unloading and prevent the wood chips from piling up for a long time, causing difficulty in unloading.
[0076] For example, Figure 1 As shown, the present invention also includes that an inspection platform 26 is provided on the outside of the material storage frame 1, a fence 27 is provided on the outside of the inspection platform 26, and an inspection staircase 28 is provided on the outside of the material storage frame.
[0077] When in use, the maintenance platform 26 and the maintenance stairs 28 can facilitate the staff to carry out maintenance on the entire structure.
[0078] For example, Figure 1 As shown, the present invention also includes that a horizontally arranged mounting rod 29 is provided below the storage frame 1, a plurality of groups of supporting legs 30 are fixedly connected below the mounting rod 29, and the lower ends of the supporting legs 30 are fixedly connected to universal casters 31.
[0079] When in use, the supporting legs 30 and the universal casters 31 can be used to drive the entire device to move, thereby improving the overall mobility.
[0080] For example, Figure 1 As shown, the present invention also includes that the corners of the material storage frame 1 are fixedly connected with reinforcing ribs 32 .
[0081] When in use, the reinforcing ribs 32 can improve the overall stability of the material storage frame 1 and prevent the material storage frame 1 from being deformed.
[0082] When the present invention is in use, wood chips are put into the storage frame 1. After the wood chips enter the storage frame 1, they fall into a plurality of groups of discharge hoppers 2. When the amount of wood chips in the discharge hopper 2 reaches a certain amount, the extrusion block 7 is driven to move by the extrusion of the wood chips. When the extrusion block 7 moves, it drives the slide bar 6 and the extrusion plate 5 to move synchronously. When the extrusion plate 5 moves, it drives the conical sealing block 11 to move, and at the same time squeezes the first spring 14 to store force. After the conical sealing block 11 moves, the conical sealing block 11 no longer blocks the first conical groove 9 and the second conical groove 10. Air enters the discharge hopper 2 through the first conical groove 9 and the second conical groove 10. At the same time, the discharge hopper 2 can be ventilated by relying on the storage frame 1 with an upward opening.
[0083] The more wood chips there are in the storage frame 1, the greater the extrusion force on the extrusion block 7. At the same time, the extrusion block 7 will further drive the slide bar 6 and the extrusion plate 5 to move. When the extrusion plate 5 moves to a certain position, the conical sealing block 11 is completely separated from the first conical groove 9 and the second conical groove 10, so that the ventilation effect in the discharge hopper 2 can be further improved, so that the ventilation efficiency can be automatically adjusted according to the amount of wood chips in the storage frame 1 and the discharge hopper 2.
[0084] When the wood chips in the discharge hopper 2 reach a certain amount, the wood chips are accumulated in the storage frame 1. The weight of the wood chips accumulated in the storage frame 1 can further drive the extrusion block 7 to move. When the extrusion block 7 moves, the slide bar 6 drives the extrusion plate 5 to move. When the extrusion plate 5 moves, it squeezes the liquid storage pad 15. When the liquid storage pad 15 is squeezed;
[0085] The liquid outlet joint 16 is connected with the expansion pad 19 in the lowermost movable plate 17, thereby driving the expansion pad 19 to expand. When the expansion pad 19 expands, it squeezes the movable plate 17 to move outward and drives the second spring 20 to store force. When the movable plate 17 moves outward, it drives the sealing rod 24 to separate from the first ventilation hole 22 and the second ventilation hole 23. When the movable plate 17 moves outward to a certain position, the sealing rod 24 separates from the first ventilation hole 22 and the second ventilation hole 23 and no longer blocks them. Air enters the material storage frame 1 through the first ventilation hole 22 and the second ventilation hole 23, thereby improving the ventilation effect in the material storage frame 1.
[0086] As the number of wood chips in the storage frame 1 increases, the squeezing force on the squeezing plate 5 increases. When the expansion pad 19 in the bottom movable plate 17 expands to the limit, the expansion pad 19 in the upper movable plate 17 is driven to expand through the communication between adjacent expansion pads 19, and the corresponding first ventilation holes 22 and second ventilation holes 23 are opened, so as to automatically adjust the ventilation efficiency of the storage frame 1 according to the amount of wood chips in the storage frame 1.
[0087] After the wood chips in the storage frame 1 are discharged, the squeezing force on the squeezing block 7 is reduced, and the liquid storage pad 15 is no longer squeezed. The movable plate 17 is driven to reset and move by the reset effect of the second spring 20, and the expansion pad 19 is squeezed at the same time, so that the liquid in the expansion pad 19 is transported to the liquid storage pad 15 through the pipeline again. When the second spring 20 drives the movable plate 17 to reset and move to a certain position, the sealing rod 24 is inserted into the first ventilation hole 22 and the second ventilation hole 23 again, and the first ventilation hole 22 and the second ventilation hole 23 can be cleaned by the reset movement of the sealing rod 24. When the sealing rod 24 moves to a certain position, the sealing rod 24 blocks the first ventilation hole 22 and the second ventilation hole 23 again, and the movable plate 17 returns to its initial state.
[0088] After the wood chips in the discharge hopper 2 are discharged, the extrusion plate 5 is driven to reset and move by relying on the reset effect of the first spring 14. When the extrusion plate 5 resets and moves, the slide bar 6 and the extrusion block 7 are driven to move synchronously. When the extrusion plate 5 resets and moves, the conical sealing block 11 is driven to move. Relying on the movement of the conical sealing block 11, the wood chips in the first conical groove 9 and the second conical groove 10 can be pushed back into the discharge hopper 2, so as to be cleaned and prevented from being blocked in the first conical groove 9 and the second conical groove 10. When the conical sealing block 11 moves to a certain position, the first conical groove 9 and the second conical groove 10 are blocked again, so that the extrusion plate 5 is restored to its initial state, which is convenient for storing the next batch of wood chips, and the ventilation efficiency is automatically adjusted according to the storage amount.
