Description

Technical Field

[0001] The invention relates to the technical field of loading and transportation, and in particular to a gantry type wood chip loading device and method for a wood chip yard. Background Art

[0002] At present, when transporting wood chips, the wood chips need to be transported to the carriage of the transport vehicle first, and the wood chips in the carriage need to be compacted and leveled to prevent the wood chips from falling from the carriage when the transport vehicle is transporting the wood chips.

[0003] The existing loading devices mostly use rollers to compact the upper part of the carriage when leveling and compacting the wood chips. During the compaction and leveling process, some wood chips on the upper part of the carriage will fall to the outside of the carriage. At this time, they need to be manually cleaned and recovered, which increases the workload. At the same time, the existing compacting devices cannot adjust the leveling and compacting according to the vehicle size of the transport vehicle. Therefore, a gantry-type wood chip loading device for a wood chip yard is proposed to facilitate automatic collection of wood chips that fall from the carriage when leveling and compacting the wood chips, reduce manual workload, and facilitate automatic adjustment of the loading device according to the vehicle size of the transport vehicle, so that the loading device can adapt to transport vehicles of different sizes. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a gantry-type wood chip loading device for a wood chip yard, which is convenient for automatically collecting wood chips that fall from the car body when the wood chips are leveled and compacted, thereby reducing manual workload. At the same time, it is convenient to automatically adjust the loading device according to the vehicle size of the transport vehicle, so that the loading device can adapt to transport vehicles of different specifications and sizes.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] By adopting the above technical scheme, when the transport vehicle needs to be leveled, the transport vehicle is moved between the two sets of support seats, and then the moving rod is driven downward by the electric slider, and the moving rod drives the mounting plate to move downward synchronously when the moving rod moves downward, and the mounting plate drives the rolling structure and the feeding structure to move downward synchronously when the mounting plate moves downward. When the rolling structure and the feeding structure move down to a certain position, the rolling structure and the feeding structure are pressed and contacted with the upper part of the carriage, so as to facilitate the adjustment of the height of the rolling structure and the feeding structure, so as to adapt to transport vehicles of different heights; at the same time, when the moving rod moves downward, the driving structure is squeezed, and the mounting plate is driven to move by the driving structure, and the rolling structure and the feeding structure are driven to be close when the mounting plate moves, so as to facilitate the adjustment of the position of the rolling structure and the feeding structure according to the width of the carriage, so that the device can adapt to transport vehicles of different sizes;

[0007] When the position adjustment of the roller structure and the feeding structure is completed, the driving roller moves on the track, thereby driving the two sets of support seats to move. When the support seats move, they rely on the feeding structure to contact the wood chips on the upper part of the car, and rely on the feeding structure to transport the wood chips to the aggregate structure. Then, the roller structure is used to roll and compact the wood chips on the upper part of the car, so as to automatically collect the wood chips that fall from the car when the wood chips are leveled and compacted.

[0008] Specifically, the driving structure includes two groups of symmetrically arranged transverse plates, the transverse plates are installed on the side close to the two groups of support seats, the transverse plates are fixedly connected to a piston cylinder, a piston plate is sealingly and slidably connected inside the piston cylinder, a vertically arranged piston rod is fixedly connected to the piston plate, the piston rod is a hollow structure, the lower end of the piston rod passes through the first piston plate and is connected to the lower part of the piston cylinder, the bottom of the piston cylinder is connected to a one-way air intake valve, and the upper end of the piston rod is connected to a pressure regulating valve;

[0009] The lower surfaces of both ends of the moving rod are fixedly connected with pneumatic telescopic rods, the upper end of the piston rod is connected to the fixed end of the pneumatic telescopic rod, the output end of the pneumatic telescopic rod is connected to the mounting plate, and the outer side of the fixed end of the pneumatic telescopic rod is connected to a damping exhaust valve.

[0010] By adopting the above technical solution, the moving rod is driven downward by the electric slider, and when the moving rod moves downward, the pneumatic telescopic rod is driven to move downward synchronously, and when the pneumatic telescopic rod moves downward, the piston rod is driven to move downward synchronously, and when the piston rod moves downward, the piston cylinder is squeezed, and at this time, the gas in the piston cylinder enters the pneumatic telescopic rod through the piston rod, and drives the output end of the pneumatic telescopic rod to extend and squeeze to drive the mounting plate to move, so that the two sets of mounting plates move closer to each other, and when the mounting plate moves, the rolling structure and the feeding structure are driven to move synchronously, so as to automatically adjust the positions of the rolling structure and the feeding structure according to the width of the transport vehicle;

[0011] When the rolling structure and the feeding structure move to a certain position, the collecting structure is in squeeze contact with the outside of the transport vehicle compartment, and the output end of the pneumatic telescopic rod cannot continue to extend. When the gas in the piston rod continues to be transported to the pneumatic telescopic rod, the gas is discharged by the damping exhaust valve, thereby ensuring the overall stability of the feeding structure, the rolling structure, and the collecting structure, and facilitating the automatic adjustment of the position of the feeding structure, the rolling structure, and the collecting structure according to the size of the transport vehicle;

[0012] When the wood chips on the transport vehicle are leveled and compacted, the electric slider drives the pneumatic telescopic rod to move upward, and when the pneumatic telescopic rod moves upward, it drives the piston rod to move upward synchronously, and when the piston rod moves upward, it drives the piston plate to move. When the piston plate moves, the external gas is drawn into the piston cylinder by the one-way air inlet valve. At the same time, the gas in the pneumatic telescopic rod can be drawn into the piston cylinder through the pressure regulating valve, so as to facilitate the shortening of the pneumatic telescopic rod, and the output end of the pneumatic telescopic rod is reset and moved, driving the feeding structure, the roller pressing structure, and the aggregate structure to reset and move synchronously, so as to facilitate the subsequent leveling and compacting operations on the next transport vehicle.

[0013] Specifically, the rolling structure includes a horizontally arranged roller and a sleeve sleeved on the outside of the roller, the outside of the roller is provided with a plurality of groups of first positioning grooves, the inside of the sleeve is provided with a plurality of groups of first positioning blocks corresponding to the first positioning grooves, the sleeve is slidably connected to the roller, the sides of the roller and the sleeve away from each other are fixedly connected with a first rotating shaft, the first rotating shaft is rotatably connected to one side of a mounting plate, the side of the mounting plate away from the first rotating shaft is fixedly connected with a first driving motor, and the output end of the first driving motor is fixedly connected to the first rotating shaft.

[0014] By adopting the above technical solution, when the moving rod moves downward, the mounting plate is driven to move downward synchronously, and when the mounting plate moves downward, the roller and the sleeve are driven to move downward synchronously by the first rotating shaft. According to the height of the transport vehicle, when the mounting plate moves downward to a certain position, the roller and the sleeve are squeezed and contacted with the wood chips on the upper part of the vehicle;

[0015] The pneumatic telescopic rod drives the mounting plates to move closer together. When the two sets of mounting plates move, the roller and the sleeve are driven to move closer together. The first positioning block is slidably connected in the first positioning groove, so as to automatically adjust the length of the rolling structure according to the width of the carriage.

[0016] When the position adjustment of the roller and the sleeve is completed, the roller rolls in the track to drive the support seat to move. When the support seat moves, the feeding structure is used to sort the wood chips on the upper part of the car, and the excess wood chips are transported to the aggregate structure. After the wood chips are sorted, the first driving motor is used to drive the first shaft to rotate, and the first shaft drives the sleeve to rotate when it rotates. When the sleeve rotates, the first positioning block drives the roller to rotate, and the rotation of the roller and the sleeve is used to roll and compact the wood chips on the upper part of the car, so as to facilitate the leveling of the wood chips placed in the car, thereby improving the convenience and efficiency of leveling.

[0017] Specifically, the feeding structure includes a horizontally arranged second rotating shaft, the second rotating shaft is provided with a symmetrically arranged spiral feeding plate, both ends of the second rotating shaft are slidably connected with a sleeve, a plurality of groups of second positioning grooves are provided on the outer sides of both ends of the second rotating shaft, a plurality of groups of second positioning blocks corresponding to the second positioning grooves are fixedly connected to the inner side of the sleeve, a spring is provided in the sleeve, one end of the spring is fixedly connected to the inner wall of the sleeve, and the other end of the sleeve is fixedly connected to one end of the second rotating shaft, the ends of the two groups of sleeves away from the second rotating shaft are rotatably connected to one side of the mounting plate, the side of the mounting plate away from the sleeve is fixedly connected to the second drive motor, and the output end of the second drive motor is fixedly connected to a group of the sleeves.

[0018] By adopting the above technical solution, when the moving rod moves downward, the mounting plate is driven to move downward synchronously, and when the mounting plate moves downward, the sleeve and the second rotating shaft are driven to move downward synchronously. According to the height of the transport vehicle, when the mounting plate moves downward to a certain position, the spiral feeding plate on the second rotating shaft contacts the wood chips on the upper part of the vehicle.

[0019] The pneumatic telescopic rod drives the mounting plates to move closer together. When the two sets of mounting plates move, the sleeve is driven to be slidably connected with the second rotating shaft. Meanwhile, the second positioning block is slidably connected with the second positioning groove. When the sleeve moves, the spring is squeezed to store force, so that the length of the second rotating shaft can be automatically adjusted according to the width of the carriage. At the same time, the position of the aggregate structure can be adjusted so that the aggregate structure contacts the outer side of the carriage, thereby ensuring the stability of the aggregate structure in use.

[0020] When the positions of the aggregate structure and the second rotating shaft are adjusted, the roller rolls in the track to drive the support seat to move. When the support seat moves, the second driving motor drives the sleeve to rotate. When the sleeve rotates, the second positioning block drives the second rotating shaft to rotate. When the second rotating shaft rotates, the spiral feeding plate is driven to rotate. The wood chips on the upper part of the carriage are transported and sorted by the rotation of the spiral feeding plate. At the same time, the wood chips are transported to the aggregate structure by the spiral feeding plate, so as to improve the convenience of leveling the wood chips. After the wood chips are sorted, the roller structure is used to roll and compact the leveled wood chips, so as to facilitate the rapid leveling and compaction of the wood chips in the carriage and improve the efficiency of leveling and compaction.

[0021] When the wood chips on the transport vehicle are leveled and compacted, the electric slider drives the pneumatic telescopic rod to move upward, and the pneumatic telescopic rod drives the piston rod to move upward synchronously when the pneumatic telescopic rod moves upward. When the piston rod moves upward, the pneumatic telescopic rod shortens, and the output end of the pneumatic telescopic rod resets and moves, driving the mounting plate and the sleeve to reset and move. At the same time, the reset action of the spring further facilitates the reset movement of the sleeve, and also facilitates the reset of the mounting plates on both sides, so as to facilitate the subsequent leveling and compaction operations on the next transport vehicle.

[0022] Specifically, the material collection structure includes a material collection box with an opening facing upward, the material collection box is fixedly connected to one side of the mounting plate, a slope is provided on the inner upper part of the material collection box, and the spiral feeding plate is located above the material collection box;

[0023] An extrusion structure is arranged inside the material collection box, and an auxiliary positioning structure is arranged outside the material collection box.

[0024] By adopting the above technical solution, the wood chips on the upper part of the carriage are transported and sorted by the rotation of the spiral feeding plate, and the wood chips are transported to the collecting box by the spiral feeding plate, and the wood chips are conveniently entered into the collecting box by the slope;

[0025] The auxiliary positioning structure can be used to easily determine the position of the collection box, ensuring that the collection box can be close to the transport vehicle for collecting wood chips. At the same time, the extrusion structure can be used to compact and shape the wood chips in the collection box.

[0026] Specifically, the auxiliary positioning structure includes a vertically arranged rotating rod, a positioning roller is fixedly connected to the rotating rod, both ends of the rotating rod are rotatably connected to connecting plates, and one end of the connecting plate away from the rotating rod is fixedly connected to the outer side of the collecting box;

[0027] The lower end of the rotating rod passes through the connecting plate and is fixedly connected with a first bevel gear, and the first bevel gear is meshed with the extrusion structure for transmission.

[0028] By adopting the above technical solution, the pneumatic telescopic rod drives the mounting plates to move closer together. When the two sets of mounting plates move, the material collecting box is driven to move synchronously. When the material collecting box moves to a certain position, the positioning roller is squeezed and contacted with the outer side of the carriage, so as to facilitate the determination of the position of the material collecting box.

[0029] When the position adjustment of the aggregate box is completed, it moves with the support seat by the roller, and the movement of the support seat drives the mounting plate and the aggregate box to move synchronously. When the aggregate box moves, the positioning roller rolls in contact with the outer side of the carriage, and drives the rotating rod to rotate at the same time, and the rotation of the rotating rod drives the first bevel gear to rotate, and the first bevel gear drives the extrusion structure to work, so that when the wood chips are transported into the aggregate box, the extrusion structure can be used to extrude and shape the wood chips in the aggregate box, which is convenient for its later recycling and there is no need to manually clean the wood chips in the aggregate box.

[0030] Specifically, the extrusion structure includes a vertically arranged extrusion plate, the extrusion plate is located in a material collection box, a hydraulic telescopic rod is provided on the outside of the material collection box, a fixed end of the hydraulic telescopic rod is fixedly connected to the outside of the material collection box, and an output end of the hydraulic telescopic rod passes through the material collection box and is fixedly connected to one side of the extrusion plate;

[0031] A horizontally arranged material baffle plate is fixedly connected to the upper part of one side of the extrusion plate close to the hydraulic telescopic rod, and one end of the material baffle plate passes through the material collection box and is slidably connected to the material collection box;

[0032] The material collecting box is provided with a piston cavity arranged symmetrically horizontally, and the piston cavity is opened in the material collecting box. Two groups of piston cavities are provided with horizontally arranged reciprocating screws, one end of the two groups of reciprocating screws passes through the material collecting box and is rotatably connected to the material collecting box, one group of reciprocating screws is provided with a second bevel gear, and the second bevel gear is meshed with the first bevel gear for transmission, and the two groups of reciprocating screws are provided with pulleys, and the two groups of pulleys are driven by a transmission belt;

[0033] The end of the reciprocating screw rod away from the pulley is threadedly connected to a reciprocating nut, and the side of the reciprocating nut away from the pulley is fixedly connected to a horizontally arranged support tube, and the end of the support tube away from the reciprocating nut is fixedly connected to a sealing plate, and the sealing plate is sealingly and slidingly connected to the piston cavity; the end of the piston cavity away from the reciprocating nut is connected to the fixed end of the hydraulic telescopic rod through a pipeline.

[0034] By adopting the above technical scheme, when the spiral feeding plate conveys the wood chips into the collecting box, the first bevel gear and the second bevel gear meshing transmission drive a group of reciprocating screws to rotate, and when one group of reciprocating screws rotates, the pulley and the transmission belt drive another group of reciprocating screws to rotate synchronously, and when the reciprocating screws rotate, the reciprocating nut is driven to move, and when the reciprocating nut moves, the support tube and the sealing plate are driven to move synchronously, and the sealing plate reciprocates to squeeze the piston cavity, and at the same time, it is connected with the fixed end of the hydraulic telescopic rod by a pipeline, so as to drive the output end of the hydraulic telescopic rod to reciprocate, and the extrusion plate is driven to move by the extrusion of the output end of the hydraulic telescopic rod, and when the extrusion plate moves, the wood chips in the collecting box are squeezed and formed, so as to facilitate recycling in the later stage;

[0035] When the extrusion plate moves, it drives the baffle plate to move synchronously. The baffle plate is slidably connected with the collecting box, and the upper part of the collecting box is blocked by the baffle plate. At this time, the spiral feeding plate conveys the wood chips to the baffle plate to prevent the wood chips from falling behind the extrusion plate and affecting the subsequent extrusion processing of the wood chips.

[0036] When the reciprocating nut moves to a certain position, the reciprocating screw rod is used to reset the nut. When the reciprocating nut resets, it drives the supporting tube and the sealing plate to reset synchronously. The movement of the sealing plate generates negative pressure in the piston chamber. The reciprocating nut resets and moves by relying on the reset movement of the hydraulic telescopic rod. When the reciprocating plate resets and moves, it drives the baffle plate to reset and move synchronously. When the baffle plate resets and moves, the wood chips accumulated on the baffle plate are squeezed and contacted with the inner wall of the collecting box, so that the wood chips fall into the collecting box again. When the extrusion plate is reset to the initial state, the reciprocating screw rod is used again to drive the reciprocating nut to drive the supporting tube and the sealing plate to move, and the movement of the sealing plate squeezes the piston chamber, thereby driving the hydraulic telescopic rod again to drive the extrusion plate to extrude and form the wood chips in the collecting box. In this way, the reciprocating movement of the reciprocating nut is relied on to further improve the convenience of wood chip recovery.

[0037] It should be pointed out that the sealing plate described in the present invention may be in a square shape, so as to improve the movement stability of the sealing plate in the piston cavity and ensure that the reciprocating nut does not rotate synchronously with the reciprocating screw.

[0038] Specifically, a discharge port is provided on one side of the collection box away from the mounting plate, and a baffle is provided on the outside of the discharge port. The upper part of the baffle is hinged to the outside of the collection box through a hinge shaft, the baffle corresponds to the discharge port, and the lower edge of the baffle is magnetically adsorbed to the collection box through a magnet.

[0039] By adopting the above technical scheme, the extrusion plate is driven to move by the output end of the hydraulic telescopic rod. When the extrusion plate moves, the wood chips in the collection box are squeezed and the wood chips are squeezed into shape. As the extrusion plate moves to a certain position, the extruded wood chips are squeezed into contact with the baffle, and as the extrusion plate continues to be squeezed, the magnet on the baffle is separated from the collection box, and the baffle is swung by the formed wood chips. When the baffle swings to a certain position, the extruded wood chips will fall from the discharge port. After the extruded wood chips fall from the discharge port, the baffle will automatically swing to its original position, thereby further improving the convenience of use.

[0071] When the rolling structure and the feeding structure move to a certain position, the collecting structure is in squeeze contact with the outside of the transport vehicle compartment, and the output end of the pneumatic telescopic rod 16 cannot continue to extend. When the gas in the piston rod 13 continues to be transported to the pneumatic telescopic rod 16, the gas is discharged by the damping exhaust valve 17, thereby ensuring the overall stability of the feeding structure, the rolling structure, and the collecting structure, and facilitating the automatic adjustment of the positions of the feeding structure, the rolling structure, and the collecting structure according to the size of the transport vehicle;

[0072] When the wood chips on the transport vehicle are leveled and compacted, the electric slider drives the pneumatic telescopic rod 16 to move upward, and when the pneumatic telescopic rod 16 moves upward, it drives the piston rod 13 to move upward synchronously, and when the piston rod 13 moves upward, it drives the piston plate 12 to move. When the piston plate 12 moves, the one-way air inlet valve 14 is used to draw external gas into the piston cylinder 11. At the same time, the gas in the pneumatic telescopic rod 16 can be drawn into the piston cylinder 11 through the pressure regulating valve 15, so as to facilitate the shortening of the pneumatic telescopic rod 16, and the output end of the pneumatic telescopic rod 16 is reset and moved, driving the feeding structure, the rolling structure, and the aggregate structure to reset and move synchronously, so as to facilitate the subsequent leveling and compacting operations on the next transport vehicle.

[0073] In order to facilitate the leveling of the wood chips placed in the carriage, for example, Figure 2 , Figure 3 , Fig.12 As shown, the present invention also includes that the rolling structure includes a horizontally arranged roller 18 and a sleeve 19 sleeved on the outside of the roller 18, the outer side of the roller 18 is provided with a plurality of groups of first positioning grooves 20, the inner side of the sleeve 19 is provided with a plurality of groups of first positioning blocks 21 corresponding to the first positioning grooves 20, the sleeve 19 is slidably connected to the roller 18, the sides of the roller 18 and the sleeve 19 away from each other are fixedly connected with a first rotating shaft 22, the first rotating shaft 22 is rotatably connected to one side of the mounting plate 9, the side of the mounting plate 9 away from the first rotating shaft 22 is fixedly connected with a first driving motor 23, and the output end of the first driving motor 23 is fixedly connected to the first rotating shaft 22.

[0074] When in use, the moving rod 6 moves downward and drives the mounting plate 9 to move downward synchronously. When the mounting plate 9 moves downward, the first rotating shaft 22 drives the roller 18 and the sleeve 19 to move downward synchronously. According to the height of the transport vehicle, when the mounting plate 9 moves downward to a certain position, the roller 18 and the sleeve 19 are pressed and contacted with the wood chips on the upper part of the vehicle.

[0075] The pneumatic telescopic rod 16 drives the mounting plates 9 to move closer to each other. When the two sets of mounting plates 9 move, the roller 18 and the sleeve 19 are driven to move closer to each other. The first positioning block 21 is slidably connected in the first positioning groove 20, so as to automatically adjust the length of the rolling structure according to the width of the carriage.

[0076] When the position adjustment of the roller 18 and the sleeve 19 is completed, the roller 3 rolls in the track 4 to drive the support seat 1 to move. When the support seat 1 moves, the feeding structure is used to sort the wood chips on the upper part of the car, and the excess wood chips are transported to the aggregate structure. After the wood chips are sorted, the first driving motor 23 is used to drive the first rotating shaft 22 to rotate. When the first rotating shaft 22 rotates, it drives the sleeve 19 to rotate. When the sleeve 19 rotates, it drives the roller 18 to rotate by the first positioning block 21. The wood chips on the upper part of the car are rolled and compacted by the rotation of the roller 18 and the sleeve 19, so as to facilitate the leveling of the wood chips placed in the car, thereby improving the convenience and efficiency of leveling.

[0077] In order to transport and sort the wood chips on the upper part of the carriage, for example, Figure 2 , Figure 3 , Figure 5 , Fig.13 As shown, the present invention also includes that the feeding structure includes a horizontally arranged second rotating shaft 24, and the second rotating shaft 24 is provided with a symmetrically arranged spiral feeding plate 25, both ends of the second rotating shaft 24 are slidably connected with a sleeve 26, and the outer sides of both ends of the second rotating shaft 24 are provided with a plurality of groups of second positioning grooves 27, and the inner side of the sleeve 26 is fixedly connected with a plurality of groups of second positioning blocks 28 corresponding to the second positioning grooves 27, and a spring 29 is provided in the sleeve 26, one end of the spring 29 is fixedly connected to the inner wall of the sleeve 26, and the other end of the sleeve 26 is fixedly connected to one end of the second rotating shaft 24, and the ends of the two groups of the sleeves 26 away from the second rotating shaft 24 are rotatably connected to one side of the mounting plate 9, and the side of the mounting plate 9 away from the sleeve 26 is fixedly connected with a second drive motor 30, and the output end of the second drive motor 30 is fixedly connected to a group of the sleeves 26.

[0078] When in use, the moving rod 6 moves downward, driving the mounting plate 9 to move downward synchronously, and the mounting plate 9 moves downward, driving the sleeve 26 and the second rotating shaft 24 to move downward synchronously. According to the height of the transport vehicle, when the mounting plate 9 moves downward to a certain position, the spiral feeding plate 25 on the second rotating shaft 24 contacts the wood chips on the upper part of the vehicle.

[0079] The pneumatic telescopic rod 16 drives the mounting plates 9 to move closer to each other. When the two sets of mounting plates 9 move, the sleeve 26 is driven to be slidably connected with the second rotating shaft 24. At the same time, the second positioning block 28 is slidably connected with the second positioning groove 27. When the sleeve 26 moves, the spring 29 is squeezed to store force, so that the length of the second rotating shaft 24 can be automatically adjusted according to the width of the carriage. At the same time, it is convenient to adjust the position of the aggregate structure so that the aggregate structure contacts the outer side of the carriage, thereby ensuring the stability of the aggregate structure in use;

[0080] When the positions of the aggregate structure and the second rotating shaft 24 are adjusted, the roller 3 is used to roll in the track 4 to drive the support seat 1 to move. When the support seat 1 moves, the second driving motor 30 is used to drive the sleeve 26 to rotate. When the sleeve 26 rotates, the second positioning block 28 is used to drive the second rotating shaft 24 to rotate. When the second rotating shaft 24 rotates, the spiral feeding plate 25 is driven to rotate. The wood chips on the upper part of the carriage are transported and sorted by the rotation of the spiral feeding plate 25. At the same time, the wood chips are transported to the aggregate structure by the spiral feeding plate 25, so as to improve the convenience of leveling the wood chips. After the wood chips are sorted, the roller pressing structure is used to roll and compact the leveled wood chips, so as to facilitate the rapid leveling and compaction of the wood chips in the carriage and improve the efficiency of leveling and compaction.

[0081] When the wood chips on the transport vehicle are leveled and compacted, the electric slider drives the pneumatic telescopic rod 16 to move upward, and when the pneumatic telescopic rod 16 moves upward, it drives the piston rod 13 to move upward synchronously. When the piston rod 13 moves upward, the pneumatic telescopic rod 16 shortens, and the output end of the pneumatic telescopic rod 16 is reset to move, driving the mounting plate 9 and the sleeve 26 to reset and move. At the same time, the reset effect of the spring 29 further facilitates the reset movement of the sleeve 26, and also facilitates the reset of the mounting plates 9 on both sides, so as to facilitate the subsequent leveling and compacting operation of the next transport vehicle.

[0082] For example, Figure 5 As shown, the present invention also includes that the material collection structure includes a material collection box 31 with an opening facing upward, the material collection box 31 is fixedly connected to one side of the mounting plate 9, a slope is provided on the inner upper part of the material collection box 31, and the spiral feeding plate 25 is located above the material collection box 31;

[0083] The material collecting box 31 is provided with an extrusion structure inside, and the material collecting box 31 is provided with an auxiliary positioning structure outside.

[0084] When in use, the wood chips on the upper part of the carriage are transported and sorted by the rotation of the spiral feeding plate 25, and the wood chips are transported to the collecting box 31 by the spiral feeding plate 25, and the wood chips are conveniently entered into the collecting box 31 by the slope;

[0085] The auxiliary positioning structure can be used to easily determine the position of the collection box 31, ensuring that the collection box 31 can be close to the transport vehicle for collecting wood chips. At the same time, the extrusion structure can be used to compact and shape the wood chips in the collection box 31.

[0086] For example, Figure 5 , Figure 6 As shown, the present invention also includes that the auxiliary positioning structure includes a vertically arranged rotating rod 32, a positioning roller 33 is fixedly connected to the rotating rod 32, both ends of the rotating rod 32 are rotatably connected to a connecting plate 34, and one end of the connecting plate 34 away from the rotating rod 32 is fixedly connected to the outer side of the collecting box 31;

[0087] The lower end of the rotating rod 32 passes through the connecting plate 34 and is fixedly connected to a first bevel gear 35 , and the first bevel gear 35 is meshed with the extrusion structure for transmission.

[0088] When in use, the pneumatic telescopic rod 16 drives the mounting plates 9 to move closer to each other. When the two sets of mounting plates 9 move, the material collecting box 31 is driven to move synchronously. When the material collecting box 31 moves to a certain position, the positioning roller 33 is pressed and contacted with the outer side of the carriage, so as to facilitate the determination of the position of the material collecting box 31.

[0089] When the position adjustment of the aggregate box 31 is completed, the support seat 1 is moved by the roller 3. When the support seat 1 moves, it drives the mounting plate 9 and the aggregate box 31 to move synchronously. When the aggregate box 31 moves, the positioning roller 33 rolls in contact with the outer side of the carriage, and at the same time drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the first bevel gear 35 to rotate. The first bevel gear 35 drives the extrusion structure to work. In this way, after the wood chips are transported into the aggregate box 31, the wood chips in the aggregate box 31 are extruded and formed by the extrusion structure, which is convenient for their later recycling. At the same time, there is no need to manually clean the wood chips in the aggregate box 31.

[0090] In order to facilitate the extrusion of wood chips and facilitate their subsequent recycling, for example, Figure 4 , Fig. 9 , Fig.10 , Fig.11 As shown, the present invention also includes that the extrusion structure includes a vertically arranged extrusion plate 36, the extrusion plate 36 is located in the material collection box 31, and a hydraulic telescopic rod 37 is provided on the outside of the material collection box 31, and the fixed end of the hydraulic telescopic rod 37 is fixedly connected to the outside of the material collection box 31, and the output end of the hydraulic telescopic rod 37 passes through the material collection box 31 and is fixedly connected to one side of the extrusion plate 36;

[0091] A horizontally arranged material blocking plate 38 is fixedly connected to the upper part of one side of the extrusion plate 36 close to the hydraulic telescopic rod 37, and one end of the material blocking plate 38 passes through the material collecting box 31 and is slidably connected to the material collecting box 31;

[0092] The material collecting box 31 is provided with a piston cavity 39 which is arranged horizontally and symmetrically, and the piston cavity 39 is opened in the material collecting box 31. Two groups of the piston cavities 39 are provided with a horizontally arranged reciprocating screw 40, one end of the two groups of the reciprocating screw 40 passes through the material collecting box 31 and is rotatably connected to the material collecting box 31, one group of the reciprocating screw 40 is provided with a second bevel gear 41, and the second bevel gear 41 is meshed with the first bevel gear 35 for transmission, and the two groups of the reciprocating screw 40 are provided with a pulley 42, and the two groups of the pulleys 42 are driven by a transmission belt 43;

[0093] The end of the reciprocating screw rod 40 away from the pulley 42 is threadedly connected to a reciprocating nut 44, and the side of the reciprocating nut 44 away from the pulley 42 is fixedly connected to a horizontally arranged support cylinder 45, and the end of the support cylinder 45 away from the reciprocating nut 44 is fixedly connected to a sealing plate 46, and the sealing plate 46 is sealed and slidably connected to the piston chamber 39; the end of the piston chamber 39 away from the reciprocating nut 44 is connected to the fixed end of the hydraulic telescopic rod 37 through a pipeline.

[0094] When in use, when the spiral feeding plate 25 conveys the wood chips into the collecting box 31, the first bevel gear 35 and the second bevel gear 41 mesh with the transmission belt 43 to drive a group of reciprocating screws 40 to rotate. When one group of reciprocating screws 40 rotates, the pulley 42 and the transmission belt 43 drive another group of reciprocating screws 40 to rotate synchronously. When the reciprocating screws 40 rotate, the reciprocating nut 44 is driven to move. When the reciprocating nut 44 moves, the support cylinder 45 and the sealing plate 46 are driven to move synchronously. The sealing plate 46 reciprocates and squeezes the piston chamber 39. At the same time, it is connected with the fixed end of the hydraulic telescopic rod 37 through a pipeline, thereby driving the output end of the hydraulic telescopic rod 37 to reciprocate. The extrusion plate 36 is driven to move by the extrusion of the output end of the hydraulic telescopic rod 37. When the extrusion plate 36 moves, the wood chips in the collecting box 31 are squeezed and formed, which is convenient for recycling in the later stage.

[0095] When the extrusion plate 36 moves, the baffle plate 38 is driven to move synchronously. The baffle plate 38 is slidably connected with the collecting box 31, and the upper part of the collecting box 31 is blocked by the baffle plate 38. At this time, the spiral feeding plate 25 conveys the wood chips to the baffle plate 38 to prevent the wood chips from falling behind the extrusion plate 36 and affecting the subsequent extrusion processing of the wood chips.

[0096] When the reciprocating nut 44 moves to a certain position, the reciprocating screw 40 is used to make the reciprocating nut 44 reset. When the reciprocating nut 44 resets, it drives the support tube 45 and the sealing plate 46 to reset synchronously. The sealing plate 46 moves to generate negative pressure in the piston chamber 39, and the extrusion plate 36 is reset by the reset movement of the hydraulic telescopic rod 37. When the extrusion plate 36 resets, it drives the baffle plate 38 to reset synchronously. When the baffle plate 38 resets, the wood chips accumulated on the baffle plate 38 are squeezed and contacted with the inner wall of the collection box 31, so that the wood chips fall into the collection box 31 again. When the extrusion plate 36 is reset to the initial state, the reciprocating screw 40 is used again to make the reciprocating nut 44 drive the support tube 45 and the sealing plate 46 to move, and the piston chamber 39 is squeezed by the movement of the sealing plate 46, so that the hydraulic telescopic rod 37 is driven again to drive the extrusion plate 36 to extrude and shape the wood chips in the collection box 31, thereby relying on the reciprocating movement of the reciprocating nut 44 to further improve the convenience of wood chip recovery.

[0097] It should be pointed out that the sealing plate 46 described in the present invention may be square in shape, so as to improve the movement stability of the sealing plate 46 in the piston chamber 39 and ensure that the reciprocating nut 44 does not rotate synchronously with the reciprocating screw.

[0098] For example, Fig. 9 , Fig.10 As shown, the present invention also includes that a discharge port 47 is provided through the side of the collection box 31 away from the mounting plate 9, a baffle 48 is provided on the outer side of the discharge port 47, the upper part of the baffle 48 is hinged to the outer side of the collection box 31 through a hinge shaft, the baffle 48 corresponds to the discharge port 47, and the lower edge of the baffle 48 is magnetically adsorbed to the collection box through a magnet 49.

[0099] When in use, the extrusion plate 36 is driven to move by the output end of the hydraulic telescopic rod 37. When the extrusion plate 36 moves, the wood chips in the collection box 31 are squeezed and formed. As the extrusion plate 36 moves to a certain position, the extruded wood chips are squeezed into contact with the baffle 48, and as the extrusion plate 36 continues to be squeezed, the magnet 49 on the baffle 48 is separated from the collection box 31, and the baffle 48 is swung by the formed wood chips. When the baffle 48 swings to a certain position, the extruded wood chips will fall from the discharge port 47. After the extruded wood chips fall from the discharge port 47, the baffle 48 will automatically swing to its original position, thereby further improving the convenience of use.

[0100] A gantry-type wood chip loading method for a wood chip yard adopts the above-mentioned gantry-type wood chip loading device for a wood chip yard, comprising the following steps:

[0101] Step 1: Drive the transport vehicle between two sets of support seats 1;

[0102] Step 2: Use the electric slider to drive the moving rod 6 to move downward to adjust the position of the rolling structure and the feeding structure;

[0103] Step 3: After the position adjustment of the roller pressing structure and the feeding structure is completed, the driving roller 3 moves on the track 4, thereby driving the two sets of support seats 1 to move. When the support seats 1 move, they contact the wood chips on the upper part of the carriage by relying on the feeding structure, and the wood chips are transported to the aggregate structure by relying on the feeding structure, and then the wood chips on the upper part of the carriage are rolled and compacted by relying on the roller pressing structure;

[0104] Step 4: After the wood chips in the transport vehicle are compacted, the electric slider drives the moving rod 6 to move upward, and at the same time, the driving roller 3 moves on the track 4 to reset the rolling structure and the feeding structure.

[0105] When the present invention is in use, when the transport vehicle needs to be leveled, the transport vehicle is moved between the two sets of support seats 1, and then the moving rod 6 is driven downward by the electric slider, and the moving rod 6 drives the mounting plate 9 to move downward synchronously when the moving rod 6 moves downward, and the first rotating shaft 22 drives the roller 18 and the sleeve 19 to move downward synchronously when the mounting plate 9 moves downward. According to the height of the transport vehicle, when the mounting plate 9 moves downward to a certain position, the roller 18 and the sleeve 19 are squeezed and contacted with the wood chips on the upper part of the carriage; at the same time, when the mounting plate 9 moves downward, the sleeve 26 and the second rotating shaft 24 are driven downward synchronously, and according to the height of the transport vehicle, when the mounting plate 9 moves downward to a certain position, the spiral feeding plate 25 on the second rotating shaft 24 contacts with the wood chips on the upper part of the carriage;

[0106] The electric slider drives the moving rod 6 to move downward, and when the moving rod 6 moves downward, the pneumatic telescopic rod 16 is driven to move downward synchronously, and when the pneumatic telescopic rod 16 moves downward, the piston rod 13 is driven to move downward synchronously, and when the piston rod 13 moves downward, the piston cylinder 11 is squeezed. At this time, the gas in the piston cylinder 11 enters the pneumatic telescopic rod 16 through the piston rod 13, and drives the output end of the pneumatic telescopic rod 16 to extend and squeeze to drive the mounting plate 9 to move, so that the two sets of mounting plates 9 move closer to each other, and drive the roller 18 and the sleeve 19 to move closer to each other, and rely on the first positioning block 21 to slide and connect in the first positioning groove 20, so as to The length of the rolling structure is automatically adjusted according to the width of the carriage; when the two sets of mounting plates 9 move close to each other, the sleeve 26 is driven to be slidably connected with the second rotating shaft 24, and the second positioning block 28 is slidably connected with the second positioning groove 27. When the sleeve 26 moves, the spring 29 is squeezed to store force, so as to automatically adjust the length of the second rotating shaft 24 according to the width of the carriage; when the mounting plates 9 move close to each other, the collecting box 31 is driven to move synchronously, and when the collecting box 31 moves to a certain position, the positioning roller 33 is squeezed and contacted with the outer side of the carriage, so as to facilitate the determination of the position of the collecting box 31;

[0107] The roller 3 rolls in the track 4 to drive the support base 1 to move. When the support base 1 moves, the second drive motor 30 drives the sleeve 26 to rotate. When the sleeve 26 rotates, the second positioning block 28 drives the second rotating shaft 24 to rotate. When the second rotating shaft 24 rotates, the spiral feeding plate 25 is driven to rotate. The wood chips on the upper part of the carriage are transported and sorted by the rotation of the spiral feeding plate 25. At the same time, the wood chips are transported to the collecting box 31 by the spiral feeding plate 25, so as to improve the convenience of leveling the wood chips.

[0108] After the wood chips are arranged, the first driving motor 23 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the sleeve 19 to rotate when the first rotating shaft 22 rotates. When the sleeve 19 rotates, the first positioning block 21 drives the roller 18 to rotate, and the wood chips on the upper part of the carriage are rolled and compacted by the rotation of the roller 18 and the sleeve 19, so as to facilitate the leveling of the wood chips placed in the carriage, thereby improving the convenience and efficiency of leveling;

[0109] The support base 1 moves by means of the roller 3. When the support base 1 moves, the mounting plate 9 and the collecting box 31 are driven to move synchronously. When the collecting box 31 moves, the positioning roller 33 rolls in contact with the outer side of the carriage, and at the same time drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the first bevel gear 35 to rotate. The first bevel gear 35 and the second bevel gear 41 are meshed with the transmission belt 43 to drive a group of reciprocating screw rods 40 to rotate. When one group of reciprocating screw rods 40 rotates, it drives another group of reciprocating screw rods 40 to rotate synchronously by means of the pulley 42 and the transmission belt 43. When the multithread rod 40 rotates, it drives the reciprocating nut 44 to move. When the reciprocating nut 44 moves, it drives the support tube 45 and the sealing plate 46 to move synchronously. The sealing plate 46 reciprocates and squeezes the piston chamber 39. At the same time, it is connected with the fixed end of the hydraulic telescopic rod 37 through a pipeline, thereby driving the output end of the hydraulic telescopic rod 37 to reciprocate. The output end of the hydraulic telescopic rod 37 squeezes and drives the squeezing plate 36 to move. When the squeezing plate 36 moves, it squeezes the wood chips in the collecting box 31 and squeezes the wood chips into shape, which is convenient for recycling in the later stage.

[0110] When the reciprocating nut 44 moves to a certain position, the reciprocating screw 40 is used to make the reciprocating nut 44 reset. When the reciprocating nut 44 resets, it drives the support tube 45 and the sealing plate 46 to reset synchronously. The sealing plate 46 moves to generate negative pressure in the piston chamber 39, and the extrusion plate 36 is reset by the reset movement of the hydraulic telescopic rod 37. When the extrusion plate 36 resets, it drives the baffle plate 38 to reset synchronously. When the baffle plate 38 resets, the wood chips accumulated on the baffle plate 38 are squeezed and contacted with the inner wall of the collection box 31, so that the wood chips fall into the collection box 31 again. When the extrusion plate 36 is reset to the initial state, the reciprocating screw 40 is used again to make the reciprocating nut 44 drive the support tube 45 and the sealing plate 46 to move, and the piston chamber 39 is squeezed by the movement of the sealing plate 46, so that the hydraulic telescopic rod 37 is driven again to drive the extrusion plate 36 to extrude and shape the wood chips in the collection box 31, thereby relying on the reciprocating movement of the reciprocating nut 44 to further improve the convenience of wood chip recovery.

[0111] When the wood chips on the transport vehicle are leveled and compacted, the electric slider drives the pneumatic telescopic rod 16 to move upward, and when the pneumatic telescopic rod 16 moves upward, it drives the piston rod 13 to move upward synchronously. When the piston rod 13 moves upward, the pneumatic telescopic rod 16 shortens, and the output end of the pneumatic telescopic rod 16 is reset to move, driving the mounting plate 9 and the sleeve 26 to reset and move. At the same time, the reset effect of the spring 29 further facilitates the reset movement of the sleeve 26, and also facilitates the reset of the mounting plates 9 on both sides, so as to facilitate the subsequent leveling and compacting operation of the next transport vehicle.
