Description

Technical Field

[0001] The utility model relates to the technical field of briquetting machines, in particular to an agricultural biomass straw briquetting device. Background Technique

[0002] Straw is the general term for the stems and leaves of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, and other crops after harvesting the seeds. More than half of the products of crop photosynthesis exist in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium, and organic matter, etc. It is a renewable biological resource with multiple uses. A straw briquetting machine is a device that crushes and compresses biomass raw materials such as straw into high-efficiency and environmentally friendly fuels or feeds. The products pressed by the straw briquetting machine are used as feeds or fuels, and can be widely used to press various biomass raw materials such as crop straws and small branches;

[0003] During the use of the existing agricultural biomass straw briquetting device, since the straw is softened by high temperature and then compressed into blocks, when the straw blocks are just discharged, they are not yet cooled and not hard enough, resulting in the straw blocks being easily broken during subsequent transportation, causing the lengths of the straw blocks to be uneven. The messy straw blocks are prone to accumulate on the conveyor belt of the turntable, causing blockage at the outlet, which is not conducive to the briquetting use of straw. Therefore, an agricultural biomass straw briquetting device is proposed. Content of the Utility Model

[0004] In view of this, the utility model provides an agricultural biomass straw briquetting device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the utility model is realized as follows: An agricultural biomass straw briquetting device includes a rotating mechanism and a briquetting mechanism; the briquetting mechanism is installed on the top of the rotating mechanism. The rotating mechanism includes a tabletop and a bottom plate. The bottom plate is arranged below the tabletop. The briquetting mechanism includes a briquetting cylinder and a pressure roller. The bottom of the briquetting cylinder is fixedly connected to the upper surface of the tabletop. The upper surface of the bottom plate is rotationally connected with a rotating shaft through a bearing. One end of the rotating shaft penetrates through the tabletop and the briquetting cylinder. The outer side wall of the rotating shaft is rotationally connected with the tabletop and the briquetting cylinder through bearings. The top of the briquetting cylinder is fixedly connected to the pressure roller. An annular die is sleeved on the outer side wall of the briquetting cylinder. A second annular plate is fixedly connected to the outer side wall of the annular die. The outer side wall of the briquetting cylinder is rotationally connected with a first annular plate through a turntable bearing. Four second support plates are symmetrically and fixedly connected to the upper surface of the tabletop. The top of the second support plate is fixedly connected to an annular baffle. An annular air nozzle is fixedly connected to the inner side wall of the annular baffle. A cold air blower is installed on the upper surface of the tabletop. The air outlet end of the cold air blower is communicated with an air outlet pipe. One end of the air outlet pipe is communicated with the air inlet of the annular air nozzle.

[0006] Further preferably, a first motor is installed on the upper surface of the tabletop. The output end of the first motor is fixedly connected with a driving pulley. The outer side wall of the rotating shaft is fixedly connected with a driven pulley. A transmission belt is wound around the outer side walls of the rotating shaft and the driven pulley.

[0007] Further preferably, an electric heating coil is wound around the outside of the briquetting cylinder. A housing is fixedly connected to the outer side wall of the briquetting cylinder and located outside the electric heating coil.

[0008] Further preferably, a feed hopper is fixedly connected to the top of the briquetting cylinder.

[0009] Further preferably, an external gear ring is fixedly connected to the lower surface of the first annular plate. A second motor is installed on the upper surface of the tabletop. The output end of the second motor is fixedly connected with a driving gear. The driving gear is meshed with the external gear ring.

[0011] Further preferably, first support plates are fixedly connected to the four corners of the bottom of the tabletop. The bottoms of the first support plates are fixedly connected to the bottom plate.

[0012] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0013] During the use of the present utility model, when the straw blocks are extruded through the ring die discharge port, they are first initially carried by the second annular plate. At the same time, the cold air discharged by the cold air blower cools the material. When the length of the material exceeds the width of the second annular plate, the material falls due to gravity and breaks at the edge of the second annular plate, falling onto the first annular plate, controlling the length and temperature of the straw blocks, making the lengths of the straw blocks relatively uniform, and after cooling the straw blocks, it is convenient for subsequent transportation and beneficial for the briquetting use of the straw.
