Description

Technical Field

[0001] The utility model relates to the technical field of quarantine and inactivation of log pests and diseases, in particular to a log microwave quarantine and inactivation carrying tray. Background Art

[0002] Logs are one of the most important imported commodities in my country. The large amount of log imports hides the problem of the spread and control of foreign pests brought with the logs, that is, the quarantine treatment problem. In the past, the world's common quarantine treatment method mainly used chemical agent methyl bromide for fumigation, but it has pollution problems. For this reason, the International Plant Protection Organization encourages contracting parties to use microwave dielectric heating to replace methyl bromide fumigation in wood quarantine treatment. The mechanism of microwave insecticide is still inconclusive. It is generally believed that there are several major effects: 1) thermal effect; 2) non-thermal effect; 3) comprehensive effect. Microwave insecticide is mainly based on thermal effect, supplemented by non-thermal effect, and is the result of the joint action of multiple effects.

[0003] The log microwave treatment system is mainly divided into a sealed cabin treatment system and a microwave tunnel treatment system. The logs are transported to a sealed cabin or a microwave tunnel through a conveyor line, and then microwaves are supplied to the sealed cabin or the microwave tunnel through a microwave irradiation antenna feed system, and then the logs can be treated with microwave insecticides. When transporting logs, in order to prevent the logs from rolling in the radial direction, a fiberglass pallet that allows microwaves to pass through is usually used to support the logs, and then the fiberglass pallet is placed on the conveyor line as an intermediate accompanying piece to carry the logs together for transportation. However, there are two problems with the current fiberglass pallets: First, the width of the placement slots of the fiberglass pallets is consistent, and it is impossible to take into account logs of different diameters. If the larger diameter logs are taken care of, the smaller diameter logs will inevitably shake, making the fiberglass pallet unstable; Second, the diameter of the logs usually gradually decreases from the root to the top, and the placement slots usually have a consistent overall width, which cannot match the change in the log diameter, resulting in radial shaking at the top of the log.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] This embodiment provides a log microwave quarantine inactivation carrying tray, such as Figures 1 to 9 As shown, it includes a metal frame 1 and a plurality of FRP beams 3, and the number of FRP beams 3 is set according to actual needs. A rectangular hollow area 2 is provided on the metal frame 1 for microwaves to pass through. The FRP beam 3 is arranged on the rectangular hollow area 2 of the metal frame 1, and the FRP beam 3 spans the rectangular hollow area 2 along the width direction of the rectangular hollow area 2, and a plurality of FRP beams 3 are arranged at intervals along the length direction of the rectangular hollow area 2. Two FRP blocks 4 are provided on the FRP beam 3, and the spacing between the two FRP blocks 4 is adjustable. The spacing adjustment direction of the two FRP blocks 4 is parallel to the spanning direction of the FRP beam 3, that is, the width direction of the rectangular hollow area 2. The spacing between the two FRP blocks 4 and the portion of the FRP beam 3 within the spacing constitute a log support groove.

[0030] When in use, firstly, the spacing of the glass fiber reinforced plastic block 4 on all the glass fiber reinforced plastic beams 3 is increased so that all positions of the log 13 can be placed in each log supporting groove, and then the length direction of the log 13 is placed in the log supporting groove, and the length direction of the log 13 is consistent with the length direction of the rectangular hollow area 2 when placed, and then the spacing of the glass fiber reinforced plastic block 4 on each glass fiber reinforced plastic beam 3 is adjusted so that the two glass fiber reinforced plastic block 4 on the glass fiber reinforced plastic beam 3 are respectively attached to the two sides of the log 13, so that the size of each log supporting groove corresponds to the diameter of the log 13 located in the groove, and the radial direction of the log 13 is limited to ensure the stability of the placement of the log 13. By adjusting the spacing of the glass fiber reinforced plastic block 4 and changing the size of the log supporting groove, it is possible to adapt to logs 13 of different diameters and the diameters of different parts of the log 13, and ensure the stability of the log 13 during transportation, and there will be no problem of radial rolling.

[0031] In this embodiment, Figures 1 to 9As shown, the side of the FRP block 4 facing the log 13 is an inclined surface, which can match the round surface of the log 13. Of course, the above is only a preferred embodiment, and the side of the FRP block 4 facing the log 13 can also be a plane, or a surface of other shapes, such as a wavy surface, which can increase the friction between the FRP block 4 and the log 13.

[0032] In this embodiment, Figures 1 to 9 As shown, the FRP cross beam 3 is a U-shaped cross beam, and a chute 5 is provided on the bottom arm of the U-shaped cross beam, and the FRP stopper 4 is slidably connected to the chute 5. A threaded rod 6 is rotatably connected to the side of the FRP stopper 4 facing away from the log 13, and the axis of the threaded rod 6 is parallel to the width direction of the rectangular hollow area 2. The two arms of the U-shaped cross beam are provided with threaded holes 7, and the threaded rods 6 on the two FRP stoppers 4 are respectively threadedly connected to the threaded holes 7 of the two arms. When the threaded rod 6 is rotated, the threaded rod 6 will move along the cross direction of the FRP cross beam 3, thereby changing the position of the FRP stopper 4 in the chute 5, and adjusting the spacing between the two FRP stoppers 4.

[0033] In order to facilitate the rotation of the threaded rod 6, in this embodiment, Figures 1 to 9 As shown, a rotating hand wheel 8 is installed at one end of the threaded rod 6 away from the glass fiber reinforced plastic block 4, and the rotating hand wheel 8 can drive the threaded rod 6 to rotate in the threaded hole 7. Further, the rotating hand wheel 8 can be treated with anti-skid, such as providing an anti-skid film layer or making a pockmarked surface treatment, making anti-skid lines, etc., to increase the friction between the hand and the hand. Of course, other components that are conducive to rotating the threaded rod 6, such as a rotating rod, can also be installed at the end of the threaded rod 6 away from the glass fiber reinforced plastic block 4, and the axis of the rotating rod is perpendicular to the axis of the threaded rod 6.

[0034] In this embodiment, Figures 1 to 9 As shown, a rotation hole is provided on the glass fiber reinforced plastic stopper 4, a bearing 9 is provided in the rotation hole, the outer wall of the bearing 9 is coaxially fixedly connected with the rotation hole, and the inner wall of the bearing 9 is coaxially fixedly connected with the other end of the threaded rod 6. The rotation connection between the threaded rod 6 and the glass fiber reinforced plastic stopper 4 is realized by the bearing 9.

[0035] Further, in this embodiment, if Figures 1 to 9 As shown, the metal frame 1 is provided with a plug-in slot 10 for the glass fiber reinforced plastic beam 3 to be plugged in. The plug-in slots 10 are mainly located on the two long sides of the rectangular hollow area 2, and the number of the plug-in slots 10 on each long side corresponds to the number of the glass fiber reinforced plastic beams 3. After the plug-in slots 10 are provided, the glass fiber reinforced plastic beams 3 can be removed from the metal frame 1, so that the glass fiber reinforced plastic beams 3 can be replaced, or the metal frame 1 can be replaced, such as replacing the damaged glass fiber reinforced plastic beams 3, the damaged metal frame 1 or the metal frame 1 with more plug-in slots 10 to accommodate more glass fiber reinforced plastic beams 3.

[0036] In order to avoid the risk of the glass fiber reinforced plastic beam 3 being separated from the metal frame 1 by simply plugging, in this embodiment, Figures 1 to 9 As shown, a first bolt hole 11 is provided on the side wall of the metal frame 1, and the first bolt hole 11 is connected to the plug-in slot 10. A second bolt hole 12 is provided at the end of the FRP beam 3, and the second bolt hole 12 corresponds to the first bolt hole 11. After the first bolt hole 11 and the second bolt hole 12 are connected by bolts, the metal frame 1 and the FRP beam 3 can be locked to prevent the FRP beam 3 from being separated from the metal frame 1.

[0037] In this embodiment, Figures 1 to 9 As shown, the metal frame 1 is a steel frame. The steel material can be Q235 steel, Q345 steel or SPAH steel. SPAH steel has extremely strong resistance to atmospheric and seawater corrosion, especially high temperature oxidation resistance, and can meet the requirements of the port environment.

[0038] In order to facilitate transportation and lifting, in this embodiment, Figures 1 to 9 As shown, a forklift operation hole (not shown) is reserved on the side of the metal frame 1 to facilitate the use of a forklift for transportation operations, and the specific position can be set according to actual needs. A lifting operation hole (not shown) can be set on the top or side of the metal frame 1 to facilitate lifting and transportation by a front crane, and the specific position can be set according to actual needs.

[0039] In this embodiment, Figures 1 to 9 As shown, the FRP material is composed of unsaturated polyester resin, glass fiber, curing agent, and accelerator. The specific proportions are 32% (mass) of unsaturated polyester resin, 65% (mass) of glass fiber, 0.3% (mass) of curing agent, and 4.1% (mass) of accelerator. The curing agent is methyl ethyl ketone peroxide. The amount of curing agent added can be appropriately increased or decreased according to the actual temperature. The accelerator is E4. The use of this component can maintain the toughness and strength of the board while ensuring that the wave transmittance is not less than 95%, so that a single FRP beam 3 can withstand the impact of a 1-ton log 13 falling from a height of 200mm.

[0040] In this embodiment, Figures 1 to 9 As shown, it also includes a glass fiber reinforced plastic bottom plate 14. The glass fiber reinforced plastic cross beam 3 is arranged on one side of the metal frame 1, and the glass fiber reinforced plastic bottom plate 14 covers and is fixed on the other side of the metal frame 1, which is conducive to receiving water condensed from steam and debris dropped from logs. The area where the glass fiber reinforced plastic bottom plate 14 is located in the rectangular hollow area 2 is a slope surface, and a drainage hole 15 is arranged at the bottom of the slope surface. The water in the glass fiber reinforced plastic bottom plate 14 will be concentrated to the bottom of the slope through the slope surface, and then discharged from the drainage hole 15 at the bottom of the slope. When in use, the glass fiber reinforced plastic bottom plate 14 contacts the conveyor line, and the glass fiber reinforced plastic cross beam 3 is upward. Of course, the glass fiber reinforced plastic bottom plate 14 can be installed or not, and the connection method of the glass fiber reinforced plastic bottom plate 14 and the metal frame 1 can be selected by bolt connection, which is convenient for disassembly.

[0041] Further, in this embodiment, if Figures 1 to 9 As shown, a filter screen is provided at the drainage hole 15, which only allows water to pass through and is used to intercept debris and the like.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
