[0029] The utility model will be further described in detail as follows by combining with the drawings:

[0030] The following description is used to disclose the utility model so that the person skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious modifications can be thought by the person skilled in the art. The basic principles of the utility model defined in the following description can be used in other embodiments, modification schemes, improvement schemes, equivalent schemes and other technical schemes without departing from the spirit and scope of the utility model.

[0031] The person skilled in the art should understand that in the disclosure of the utility model, the orientation or position indicated by the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, which is only for the simplified description of the utility model for the convenience of description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore the above-mentioned terms cannot be understood as the limitation of the utility model.

[0032] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as the limitation of the number.

[0033] Embodiment one, as Figures 1 to 4As shown in the drawings, a kind of bamboo base composite pallet, including pallet body 1, the embedded bamboo base frame 2 of described pallet body 1, the bamboo base frame 2 is the multi-layer structure by bamboo strip 3 laying fixed, bamboo strip 3 in the same layer is spaced apart, bamboo strip 3 of adjacent upper and lower layers staggered arrangement, so that the three-dimensional cavity 2a is formed in the bamboo base frame 2, the pallet body 1 is molded by thermoplastic material, the thermoplastic material fills three-dimensional cavity 2a, and forms the thermoplastic material layer 4 wrapped in the outer periphery of bamboo base frame 2 and permeates into three-dimensional cavity 2a.

[0034] In the embodiment, the bamboo base frame 2 is provided with 3 layers, the first layer and the third layer bamboo strip 3 are arranged along the length direction of the pallet body 1, the second layer bamboo strip 3 is arranged along the width direction of the pallet body 1, the bamboo strip 3 in the same layer is parallel and spaced apart, and the bamboo strip 3 of adjacent upper and lower layers is perpendicular to each other.

[0035] The bamboo strip 3 of the bamboo base frame 2 is fixed at the intersection by a binding member, a gun nail or a screw. The binding member can be a steel wire, an iron wire, a strap, etc. The above fixing structure is convenient to operate and low in manufacturing cost.

[0036] The bamboo strip 3 is fixed to form the bamboo base frame 2, so that the structure of the bamboo base frame 2 can remain stable in the subsequent molding process, and the bamboo strip 3 is prevented from moving away from the set position. In the process of making the bamboo base frame 2, the bamboo strip 3 can also be glued and fixed at the intersection to form the bamboo base frame 2.

[0037] In the bamboo base frame 2, the adjacent bamboo strip 3 in the same layer of bamboo strip layer is spaced apart by 0.15 to 3 times the width of the bamboo strip 3. In the same layer of bamboo strip layer, the bamboo yellow of the adjacent bamboo strip 3 is oppositely arranged; in other words, the bamboo yellow of one bamboo strip 3 is arranged downward, and the bamboo yellow of the adjacent bamboo strip 3 is arranged upward. The bamboo is composed of bamboo green, bamboo flesh and bamboo yellow from outside to inside. Since there is a difference in shrinkage rate between bamboo green and bamboo yellow, when the bamboo is heated, due to the large shrinkage rate of bamboo yellow and the small shrinkage rate of bamboo green, an inward pulling force is generated, causing the bamboo to bend towards the bamboo yellow direction. The bamboo yellow of the bamboo strip 3 is arranged in a staggered manner, so that the bending forces of the adjacent bamboo strip 3 can offset each other, so that the stability and strength of the bamboo base frame 2 are better.

[0038] According to the size specification of the brick machine pallet, the thickness of the bamboo strip 3 can be set to 4-20mm, and the bamboo base frame 2 is provided with 2-8 layers of bamboo strip layers.

[0039] As shown in the drawings, Figure 2 The bamboo base frame 2 does not expose the surface of the thermoplastic material layer 4. In this way, the consistency of the surface material can be ensured, so that the surface has consistent wear resistance, and the wear difference caused by inconsistent materials can be avoided during use.

[0040] In example two,Figures 5 to 6 As shown, the tray structure in this embodiment is similar to that in Embodiment 1. The difference is that in this embodiment, the bamboo strip 3 is at a 45° angle to the length direction of the tray body 1.

[0041] Specifically, in this embodiment, the bamboo base frame 2 is provided with 3 layers, and the bamboo strips 3 are arranged at an angle. The first and third layers of bamboo strips 3 are inclined to the right at a 45° angle along the length of the tray body 1, while the second layer of bamboo strips 3 is inclined to the left at a 45° angle along the length of the tray body 1. Similarly, the bamboo strips 3 in the same layer are arranged in parallel, and the bamboo strips 3 of adjacent upper and lower layers are perpendicular to each other.

[0042] Example 3, as Figure 7 As shown, as an extension, some layers of bamboo strips 3 can be arranged longitudinally. Preferably, adjacent layers of bamboo strips 3 have different bamboo pith orientations. In odd-numbered layers, bamboo strips 3 are arranged laterally, i.e., the bamboo pith faces upwards or downwards; in even-numbered layers, bamboo strips 3 are arranged longitudinally, i.e., the bamboo pith faces left or right. Since the brick machine pallet mainly bears the longitudinal load, the use of longitudinally arranged bamboo strips 3 at intervals can further improve the load-bearing capacity and extend the service life of the brick machine pallet. In this embodiment, a total of 3 layers of bamboo strips are set. The bamboo strips 3 in the middle layer are arranged longitudinally, and two bamboo strips 3 are joined together to form a group. In the same group, the bamboo pith faces inwards.

[0043] This utility model discloses a bamboo-based composite pallet with a reasonable structure. It uses a bamboo frame (bamboo material) and thermoplastic materials to form a composite structure, reducing manufacturing costs while ensuring strength. Using bamboo to make the frame is convenient and inexpensive. The bamboo frame 2 has a multi-layered structure forming a three-dimensional cavity 2a. This cavity 2a allows the thermoplastic material to better bond with the bamboo frame 2, improving the bonding force and thus increasing the pallet's strength. The outer layer of the pallet is made of thermoplastic material, which has good strength and wear resistance, making it suitable for use as a brick machine pallet.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
