The square sleeve is connected to the card, and a square card block and spring are provided inside the square sleeve. The rotating rod is located on both sides of the square sleeve, with one end rotatably connected to the square sleeve and the other end connected to the handrail. This utility model has the advantages of being safe, hygienic and easy for a single person to operate. However, the above-mentioned raw material transfer device for the production of Chinese toon vegetables cannot expand its space according to the amount of single transport during use, and its functionality is poor. If the amount of single transport increases, it is necessary to transport it once more, which increases the workload and transportation cost. Therefore, it is necessary to provide a new raw material transfer trolley for polyurethane production to solve the above problems. Utility Model Content

[0004] The technical content of this utility model is to provide a new type of raw material transfer trolley for polyurethane production.

[0005] To address the aforementioned problems, this utility model provides a raw material transfer trolley for polyurethane production, comprising: a trolley body with four omnidirectional wheels rotatably connected to its bottom, all of which are anti-slip wheels; a push rod fixedly connected to the top of the trolley body, the push rod being fitted with a rubber sleeve; and an expansion assembly including two rotating shafts fixedly connected to the top of the trolley body. First, the device is placed in a suitable position. During daily use, raw materials can be directly stacked on top of the expansion plates, and then the trolley body is pushed to achieve transfer and transport. When the single transport volume needs to be increased, the expansion plates are rotated along the rotating shafts by moving the slots, causing the two expansion plates to unfold, thereby expanding the space at the top of the trolley body and increasing the planar area for increasing the transport volume of raw materials. While the expansion plates are rotating and expanding, a sliding frame extends outward along the sliding groove of the trolley body by moving a lever, simultaneously supporting the expansion plates to achieve stable support and improve stability during use.

[0006] As a further solution of this utility model, the expansion assembly also includes two expansion plates, which are respectively fixedly connected to the top of two rotating shafts. The expansion plates can rotate along the rotating shafts to realize the planar space of the entire vehicle body top, thereby improving the load-bearing capacity of the overall device.

[0007] As a further solution of this utility model, two sliding frames are slidably connected inside the vehicle body, and two paddles are fixedly connected to the outside of each of the two sliding frames. The sliding frames can extend outward from inside the vehicle body to provide horizontal support for the extended expansion plate.

[0008] As a further solution of this utility model, the interior of the vehicle body is provided with four sliding grooves, and each of the four sliding grooves is slidably connected to a sliding block. The four sliding blocks are fixedly connected to the outside of the sliding frame in pairs. The sliding grooves can store and limit the sliding frame.

[0009] As a further solution of this utility model, both of the expansion plates are provided with slots on their exteriors, which allow the user to apply force to rotate the expansion plates.

[0010] As a further solution of this utility model, the two sliding frames are evenly provided with insertion holes inside, and two insertion rods are slidably connected inside the vehicle body. The insertion rods can be locked inside the insertion holes to limit the sliding frame to the inside of the sliding groove.

[0011] As a further solution of this utility model, two threaded grooves are opened inside the vehicle body, and a threaded head is fixedly connected to the end of the insertion rod. The threaded head and the threaded groove can fit together to limit the insertion rod to the inside of the vehicle body.

[0012] As a further solution of this utility model, a threaded column is fixedly connected to the outside of the vehicle body, and an adjusting bolt is rotatably connected to the outside of the threaded column. The adjusting bolt can be rotated to move up and down along the outside of the threaded column. When the adjusting bolt touches the bottom, it can limit the overall device to prevent displacement.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] Firstly, this utility model describes a raw material transfer trolley for polyurethane production. It describes that the device is first placed in a suitable position. In daily use, the raw materials can be directly stacked on the top of the extension plate, and then the trolley body is pushed to realize the transfer and transportation.
