[0003] Existing storage pallets, such as the one disclosed in announcement number CN221563841U, involve an outer shell with a first cover plate fixedly connected to the top. Currently, storage pallets are frequently used in the storage and transportation of goods. Existing pallets are mostly made of plastic, which is not environmentally friendly. To protect the environment, rice husks and sawdust are used as raw materials for pallet production. However, rice husks and sawdust have significant particle size variations, making bonding difficult even with adhesives. If the two are not mixed evenly, the quality of the finished pallet cannot be guaranteed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-6A raw material mixing device for rice husk and sawdust pallets used in storage includes a body 1 with an upper cavity 101 and a lower cavity 102. A crushing shaft 3 is rotatably installed in the upper cavity 101, and a stirring shaft 4 is rotatably installed in the lower cavity 102. The body 1 is equipped with a crushing mechanism located in the upper cavity 101 via the crushing shaft 3 and the stirring shaft 4. The crushing mechanism is used to crush granular rice husk and sawdust into powder. The crushing shaft 3 and the stirring shaft 4 are driven to rotate by a drive motor. The rotation of the stirring shaft 4 drives the rotation of a horizontal plate 8, and the active wedges 9 fixedly connected to both ends of the horizontal plate 8 rotate. During the process, the driven wedge 7 is pushed to move vertically upward. The driven wedge 7 loses the thrust of the active wedge 9 and moves vertically downward under the action of gravity, so as to achieve the purpose of moving the driven wedge 7 back and forth in the vertical direction. The lifting frame 5, which is fixedly connected to the driven wedge 7, moves back and forth in the vertical direction. The lifting crushing barrel 6, which is fixedly installed on the lifting frame 5, is repeatedly raised and lowered, so that the crushing shaft 3 makes multi-level contact with the rice husk wood chips at different depths in the lifting crushing barrel 6 during the rotation, so as to crush the granular rice husk wood chips into powder. The powdered rice husk wood chips enter the feeding pipe 2 through the hole opened at the bottom of the lifting crushing barrel 6.

[0031] The machine body 1 is equipped with a feeding pipe 2 that conveys rice husk wood chips from the upper cavity 101 to the lower cavity 102. The feeding pipe 2 includes a main pipe 201 that connects to the upper cavity 101 and extends into the lower cavity 102. A secondary pipe 202 that connects to the lower cavity 102 is integrally connected to the middle end of the main pipe 201. A guide elongated hole 203 is opened at the lower end of the main pipe 201. Powdered rice husk wood chips are conveyed into the feeding pipe 2 through the hole at the bottom of the lifting crushing bucket 6. The powdered rice husk wood chips enter the lower cavity 102 from the secondary pipe 202. In order to prevent the powdered rice husk wood chips from being blocked in the feeding pipe 2, a piston rod 11 is movably arranged in the main pipe 201. A support rod 10 is fixedly connected to the piston rod 11. The support rod 10 passes through the guide elongated hole 203 and is fixedly connected to the lifting frame 5. When the stirring shaft 4 is activated, the stirring shaft 4 drives the lifting frame 5 to repeatedly rise and fall, thereby pulling the piston rod 11 to push back and forth vertically in the main pipe 201, accelerating the air circulation in the feeding pipe 2.

[0032] The machine body 1 is equipped with a mixing mechanism located in the lower cavity 102 via the stirring shaft 4. The mixing mechanism includes a support rod 10 fixedly connected to the support ring 503. The support rod 10 passes through the guide hole 203 and extends to the other end of the main pipe 201. A piston rod 11 is fixedly connected to the other end of the main pipe 201 and is slidably fitted in the lower end of the main pipe 201. The bottom end of the piston rod 11 is fixedly connected to a linkage disc 12 located outside the main pipe 201. A ring groove 13 is opened at the bottom of the linkage disc 12. A traction connecting rod 16 is pin-connected between the slider 14 and the opening and closing stirring shaft 15. When the stirring shaft 4 is started to rotate, the horizontal plate 8 rotates, driving the linkage disc 12 to move back and forth in the vertical direction. The linkage disc 12 has a slider 14 symmetrically mounted on it through the annular groove 13, which simultaneously drives the opening and closing stirring shaft 15, which is movably mounted on the horizontal plate 8, to rotate. The opening and closing stirring shaft 15, which is rotatably pulled by the slider 14, is rotatably mounted on the horizontal plate 8, so that the opening and closing stirring shaft 15 deflects up and down during the rotation, increasing the contact with the powdered rice husk and sawdust, and ensuring the stirring effect.

[0033] It should be noted that the specific model and specifications of the crushing shaft 3 and the stirring shaft 4 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] Pour the granular rice husk wood chips into the lifting crushing bucket 6 in the upper chamber 101 from the feed port at the top of the machine body 1. Start the crushing shaft 3 and the stirring shaft 4 to rotate. The crushing shaft 3 rotates and crushes the granular rice husk wood chips in the storage tube.

[0036] The stirring shaft 4 drives the horizontal plate 8 to rotate, causing the active wedge 9 and the driven wedge 7 to make intermittent contact. At the same time, due to gravity, the lifting frame 5 moves back and forth between the upper cavity 101 and the lower cavity 102, thereby supporting the lifting crushing barrel 6 to move back and forth in the vertical direction, realizing the up and down tumbling of rice husk wood chips in the lifting crushing barrel 6, so that the rice husk wood chips and the crushing shaft 3 are in full contact. The granular rice husk wood chips are crushed into powder and passed through the leakage hole at the bottom of the lifting crushing barrel 6 and conveyed into the feeding pipe 2.

[0037] The lifting frame 5 drives the piston rod 11 to move up and down in the main pipe 201 through the support rod 10, which accelerates the movement of the powdered rice husk wood chips in the feeding pipe 2, so that the powdered rice husk wood chips enter the lower chamber 102 through the secondary pipe 202.

[0038] The stirring shaft 4 drives the horizontal plate 8 to rotate, causing the opening and closing stirring shaft 15 to rotate horizontally. The opening and closing stirring shaft 15 drives the slider 14 to move around the annular groove 13 through the traction connecting rod 16, so that the opening and closing stirring shaft 15 deflects up and down during the rotation, stirring the powdered rice husk and sawdust until it is evenly mixed.

[0039] Open the discharge port to output uniformly mixed powdered rice husk wood chips.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
