[0028] In combination Figs. 1-3 , the present application provides a tray 1, which comprises a support frame 11 and a panel 12 arranged on the support frame 11. The panel 12 comprises a middle layer and wear-resistant layers and isolation layers arranged on the upper and lower surfaces of the middle layer, and the material of the middle layer is plant fiber mud. Through the environmental protection of plant fiber mud, combined with the wear-resistant layer on its surface, a durable and environmentally friendly tray 1 is obtained.

[0029] Among them, plant fiber is a kind of renewable resource widely existing in nature. These fibers come from the stems, roots, leaves or seeds of plants, so we can get them in a sustainable way without depleting the resources of the earth. At the same time, plant fiber is biodegradable, which means that when they are discarded, they can be naturally decomposed and will not leave lasting pollution in the environment. Therefore, plant fiber is a renewable and biodegradable environmentally friendly resource.

[0030] For convenience of description, the length direction of the tray 1 is defined as the longitudinal direction, and the width direction is defined as the transverse direction.

[0031] Specifically, the support frame 11 comprises at least three longitudinal beams 111 arranged in parallel and spaced apart, a top cross beam 112 connected to the top of the longitudinal beams 111, and a bottom cross beam 113 connected to the bottom of the longitudinal beams 111. The at least three longitudinal beams 111 are arranged in transverse direction and spaced apart. Each longitudinal beam 111 extends in longitudinal direction.

[0032] In the embodiment, the number of the longitudinal beams 111 is three. In other embodiments, the number of the longitudinal beams 111 can also be other, which is set according to actual conditions.

[0033] The cross section of the longitudinal beam 111 is square. In the embodiment, the vertical dimension of the longitudinal beam 111 is greater than the transverse dimension, i.e. the height of the longitudinal beam 111 is greater than the width.

[0034] The longitudinal beam 111 comprises a top wall, a bottom wall, and two side walls, which enclose the longitudinal beam 111 with square cross section.

[0035] Preferably, the top wall comprises two unit plates arranged in transverse direction and spaced apart. A plurality of accommodating grooves 1112 with top openings are arranged in longitudinal direction on the top wall. The accommodating grooves 1112 are through in transverse direction, and a connecting piece 114 in U shape is arranged in the accommodating groove 1112. In the embodiment, the number of the accommodating grooves 1112 is three. One of the accommodating grooves 1112 is arranged at the center of the longitudinal beam 111, and the other two accommodating grooves 1112 are arranged at the ends. In other embodiments, the number of the accommodating grooves 1112 and the arrangement position of the accommodating grooves 1112 can be set according to actual conditions.

[0036] The longitudinal beam 111 is provided with a forklift groove 1111 through in transverse direction. Two forklift grooves 1111 are arranged in longitudinal direction and spaced apart on each longitudinal beam 111. The forklift grooves 1111 and the accommodating grooves 1112 are arranged in longitudinal direction and spaced apart. In the embodiment, the longitudinal both ends of each forklift groove 1111 are provided with the accommodating grooves 1112.

[0037] The longitudinal beam 111 further comprises a reinforcing piece 115 arranged on a circle of the inner wall of the forklift groove 1111, so as to increase the strength of the forklift groove 1111. Further, the longitudinal beam 111 further comprises a supporting piece 116 arranged on the top of the forklift groove 1111, which is in inverted U shape. The supporting piece 116 is fixedly connected to the top and the upper part of the two side parts of the reinforcing piece 115.

[0038] The end of the longitudinal beam 111 is further provided with an inclined surface inclined from the bottom to the upper part and an end surface vertically upward from the inclined surface. The end of the longitudinal beam 111 is further provided with an end plate 117 to block the opening.

[0039] The top cross beam 112 is connected to the top of the longitudinal beam 111. Specifically, the top cross beam 112 is arranged in the accommodating groove 1112 and fixedly connected with the connecting piece 114, so as to realize the fixed connection with the longitudinal beam. The cross section of the top cross beam 112 is a trapezoidal shape, which is tapered from top to bottom. The shape of the accommodating groove 1112 is matched with the top cross beam 112, that is, the caliber of the accommodating groove 1112 is tapered from top to bottom. The shape of the connecting piece 114 is matched with the top cross beam 112.

[0040] When the top cross beam 112 is located in the accommodating groove 1112, the top of the top cross beam 112 is flush with the top of the longitudinal beam 111, which ensures the flatness of the panel 12 located on the top of the top cross beam 112. Moreover, the panel 12 is supported by the top cross beam 112 and the longitudinal beam 111, which can better share the load on the panel 12.

[0041] The bottom cross beam 113 is connected to the top of the longitudinal beam 111. Specifically, the top of the bottom cross beam 113 is arc-shaped, and the bottom is planar. The bottom of the longitudinal beam 111 is provided with a downwardly open groove 1113, which penetrates in the transverse direction. The top wall of the groove 1113 is arc-shaped. The bottom cross beam 113 is accommodated in the groove 1113, so as to realize the fixed connection with the three longitudinal beams 111. The bottom of the bottom cross beam 113 is flush with the bottom of the longitudinal beam 111.

[0042] The arc shape of the top of the bottom cross beam 113 plays a guiding role, which facilitates the wheels to enter or exit along the arc shape.

[0043] In the embodiment, the bottom cross beam 113 is arranged in one-to-one correspondence with the top cross beam 112, that is, the number of the bottom cross beam 113 is consistent with the number of the top cross beam 112. Further, the bottom cross beam 113 is located directly below the corresponding top cross beam 112.

[0044] The support frame 11 further comprises a sealing plate 118 arranged at the groove 1113 at the bottom of the longitudinal beam 111. Both ends of each bottom cross beam 113 are provided with a sealing plate 118. That is, the bottom of the longitudinal beam 111 located in the middle is not provided with a sealing plate 118, and the outer side of the longitudinal beam 111 located at both ends is provided with a sealing plate 118.

[0045] The material of the support frame 11 is steel, which ensures the support strength of the entire tray 1. Specifically, the material of the support frame 11 is high-strength steel. High-strength steel refers to steel with higher tensile strength and yield point than soft steel.

[0046] The panel 12 is arranged on the support frame 11. The panel 12 is arranged on the top of the top cross beam 112, so that when the forklift is inserted, the top cross beam 112 is contacted, avoiding direct contact with the panel 12, thereby protecting the panel 12.

[0047] The panel 12 is connected with the top cross beam 112 and / or the longitudinal beam 111 by self-tapping nails, rivets or bolts. That is, the panel 12 can be connected with only the top cross beam 112, only the longitudinal beam 111, or both the top cross beam 112 and the longitudinal beam 111, by self-tapping nails, rivets or bolts.

[0048] Specifically, the panel 12 comprises an intermediate layer, and a wear-resistant layer and an isolation layer arranged on the upper and lower surfaces of the intermediate layer. The material of the intermediate layer is plant fiber mud.

[0049] In this embodiment, the components of the plant fiber mud mainly include cement and natural plant fibers. The two are mixed in different proportions according to needs. The plant fiber mud can also include quartz sand and other minerals. Since natural plant fibers are used, and the plant fiber mud does not contain asbestos, formaldehyde or other harmful substances, the plant fiber mud is a green and environmentally friendly material.

[0050] The plant fiber cement is low in price, high in strength, light in weight, and recyclable. The plant fiber cement can also be bent and shaped.

[0051] The thickness of the intermediate layer is greater than or equal to 6 mm, so as to ensure that the panel 12 has good strength.

[0052] The wear-resistant layer is formed on the upper surface of the intermediate layer. Specifically, the material of the wear-resistant layer is Teflon and polyurea. In this embodiment, polyurea is selected for the wear-resistant layer. The wear-resistant layer increases the wear resistance of the entire panel 12, and also ensures the flatness of the upper surface of the panel 12. The wear-resistant layer is also waterproof, which prevents the plant fibers in the intermediate layer from absorbing water and increasing the weight, thereby ensuring the weight of the entire tray 1.

[0053] The thickness of the wear-resistant layer is greater than or equal to 0.5 mm, so as to ensure sufficient wear resistance. The specific thickness of the wear-resistant layer can be selected according to actual needs.

[0054] The isolation layer is formed on the lower surface of the intermediate layer. Specifically, the material of the isolation layer is powder coating. The isolation layer is waterproof, which prevents the plant fibers in the intermediate layer from absorbing water and increasing the weight, thereby ensuring the weight of the entire tray 1. At the same time, the isolation layer also prevents the debris in the plant fiber mud in the middle from falling off. The isolation layer is formed on the intermediate layer by spraying.

[0055] The thickness of the isolation layer is greater than or equal to 60 μm, so as to ensure sufficient isolation and waterproof effect.

[0056] The circumferential side of the intermediate layer is preferably also provided with a protective layer. The protective layer can be made of the same material as the isolation layer, which can isolate the intermediate layer from water. The thickness of the intermediate layer is greater than or equal to 60 μm.

[0057] In combination Fig. 2And Fig. 3 The tray 1 comprises corner portions 13 arranged at four corners of the panel 12, and the panel 12 and the corner portions 13 jointly form a square structure. That is, the four corners of the square structure are the corner portions 13, and other positions except the corner portions 13 are the panel 12. The corner portions 13 are made of steel or polypropylene. The corner portions 13 made of steel or polypropylene can effectively ensure the strength of the corners of the square structure, and avoid damage of the corner portions 13 due to knocking when the tray 1 falls.

[0058] It can be understood that, when the corner portions 13 are not arranged, the panel 12 directly presents a square shape.

[0059] The corner portions 13 have a transverse dimension not greater than a transverse dimension of the corresponding longitudinal beams 111. That is, the width of the corner portions 13 is not greater than the width of the longitudinal beams 111 arranged at the bottom of the corner portions 13.

[0060] In the embodiment, the corner portions 13 present a triangular shape. Further, the corner portions 13 present an isosceles right triangle. In other embodiments, the corner portions 13 can also have other shapes, as long as the panel 12 can be combined with the corner portions 13 to form a square structure.

[0061] In summary, the tray 1 has the following advantages:

[0062] 1. The panel 12 is environmentally friendly and durable by the environmental protection of the plant fiber mud and the wear-resistant layer on the upper surface, so that the tray 1 is not only environmentally friendly and durable, but also has high strength.

[0063] 2. The lower surface of the panel 12 adopts an isolation layer, and the isolation layer adopts a powder coating, which can play a waterproof isolation role, thereby saving costs.

[0064] 3. The cooperation of the panel 12 and the corner portions 13 made of steel or polypropylene ensures the strength of the corners and avoids damage of the corner portions 13 due to knocking when the tray 1 falls.

[0065] 4. The support frame 11 adopts a steel structure to ensure the strength of the entire tray 1. The top of the bottom longitudinal beam 113 presents an arc shape, which plays a guiding role and facilitates the entry and exit of the ground ox.

[0066] 5. The panel 12 is arranged on the top longitudinal beam 112, so that the forklift contacts the top longitudinal beam 112 when the forklift is inserted and taken out, thereby avoiding contact between the panel 12 and the forklift, and protecting the top longitudinal beam 112 well.

[0067] While the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation.
