[0002] Biodegradable mulch film is a new type of agricultural covering material that decomposes in the natural environment through the action of microorganisms. Its main components are biodegradable polymers such as polylactic acid and poly(butylene adipate / terephthalate).

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-6 An oil supply and heat preservation device includes a heating shaft 1 and a fluid heating device 2 for heating liquid. Both ends of the heating shaft 1 are rotatably connected to a sealing rotating frame 3. Several fluid channels 8 are opened inside the heating shaft 1, penetrating both ends of the heating shaft 1. Two conveying pipes 5 are provided on the side of the fluid heating device 2. Several branch pipes 6 are provided on the side of the two conveying pipes 5 away from the fluid heating device 2, which are connected to and communicate with the inside of the heating shaft 1. The positions of the branch pipes 6 and the fluid channels 8 are adapted to each other. Both ends of the heating shaft 1 are rotatably connected to a connecting ring 4. Several fastening bolts 9 threadedly connected to the connecting ring 4 are passed through one side of the sealing rotating frame 3. Sealing elements 10 with sealing effect are embedded between the sealing rotating frame 3 and the connecting ring 4 and between the sealing rotating frame 3 and the end of the heating shaft 1. Rotating shafts 11 are fixedly installed at both ends of the heating shaft 1. The rotating shafts 11 penetrate the sealing rotating frame 3 and are rotatably connected to it. Rotating limit grooves 12 are provided on the side of the rotating shaft 11.

[0029] The specific implementation method in this embodiment is as follows: Several heating shafts 1 are fixedly installed on the biodegradable membrane production line. A rotating shaft 11 is used to snap onto a rotating ring on the biodegradable membrane production line. A rotating limiting groove 12 is used to limit the rotation ring. A sealing rotating frame 3 is snapped onto the side of a connecting ring 4 and limited by fastening bolts 9. The sealing element 10 is a sealing ring or a sealing skeleton to achieve sealing between the sealing rotating frame 3 and the heating shaft 1. The heating shaft 1 can be driven by an external driving component to rotate the rotating shaft 11 to transport the biodegradable membrane. The fluid heating device 2 is a known technology that can heat liquids (such as heat transfer oil). The liquid heated to a specified temperature is transported to the fluid channel 8 inside the heating shaft 1 through a conveying pipe 5 and a branch pipe 6, and then flows back to the fluid heating device 2 through the conveying pipe 5 at the other end for heating at a specified temperature. The biodegradable membrane is heated by heating the heating shaft 1, eliminating the need to transport the biodegradable membrane to another heating device for heating, thus improving the efficiency of biodegradable membrane production.

[0030] The fluid heating device 2 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the specification. The fluid heating device 2 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection line. The main controller can be a conventional known device such as a computer that plays a control role.

[0031] Example 2

[0032] Please see Figure 2 and Figure 3 This embodiment includes the above embodiment, and further includes: the heating shaft 1 has several fluid channels 8 arranged in a funnel shape according to the liquid flow direction, and the wall thickness of the heating shaft 1 at the liquid inlet position is greater than the wall thickness of the heating shaft 1 at the liquid outlet position.

[0033] In this embodiment, the specific implementation method is as follows: When the heated liquid is transported into the heating shaft 1, since the heating shaft 1 has a certain length and the heating shaft 1 always has a heat exchange effect, the heat carried by the liquid will be consumed when the liquid is transported from one end of the fluid channel 8 to the other end. The wall thickness between the heating shaft 1 and the fluid channel 8 will gradually decrease in the direction of liquid flow. The inclination of the fluid channel 8 is proportional to the temperature of the liquid and the temperature to be heated, so as to ensure the temperature uniformity of the surface of the heating shaft 1 and improve the uniformity of heating the biodegradable membrane.

[0034] Example 3

[0035] Please see Figure 5This embodiment includes all the above embodiments, and further includes: a funnel-shaped positioning frustum 13 is fixedly installed on the side of the rotating shaft 11, a positioning groove 14 adapted to the positioning frustum 13 is opened through the side of the sealing rotating frame 3, and a locking ring 15 for positioning the sealing rotating frame 3 is threadedly connected to the side of the rotating shaft 11.

[0036] In this embodiment, the rotating shaft 11 passes through the sealing rotating frame 3, and the positioning frustum 13 is engaged in the positioning groove 14. The positioning frustum 13 and the positioning groove 14 are adapted frustum-shaped. The locking ring 15 is threadedly connected to the side of the rotating shaft 11 to center and position the heating shaft 1 and the sealing rotating frame 3, thereby improving the effect of the heating shaft 1 in transporting the biodegradable membrane.
