Description

Technical Field

[0001] The present application relates to the technical field of straw processing, and in particular to a straw briquetting pretreatment device. Background Art

[0002] Straw briquetting machine is a device that crushes and compresses biomass materials such as straw into efficient and environmentally friendly fuel or feed. The products pressed out by the straw briquetting machine are used as feed or fuel. After practice and continuous improvement, the straw briquetting machine has been perfected. The straw briquetting machine has the advantages of high degree of automation, high output, low price, low power consumption, simple operation and no pollution to the environment. Therefore, the straw briquetting machine can be widely used to press various biomass materials such as crop straw and small branches.

[0003] Before briquetting, the straw needs to be cut. For example, the Chinese patent with announcement number CN214430340U discloses a pre-processing chopping device for a straw briquetting machine. A cutting knife is used to cut the straw to reduce the situation where the straw is offset during chopping, resulting in insufficient or no chopping. This avoids repeated work of the chopping device and improves the chopping efficiency. However, after the cutting process, manual material removal is required and there is no pushing structure, which makes it inconvenient to unload the cut straw into multiple sections, resulting in difficulty in unloading and the inability to unload all the material at once. Therefore, a straw briquetting pre-processing device is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a straw briquetting pretreatment device. Figure 1-3A straw briquetting pretreatment device comprises a briquetting table 1, wherein the lower end of the briquetting table 1 is fixedly connected to a fixing plate 8, the upper end of the rear of the fixing plate 8 is fixedly connected to a mounting plate 2, a cutter 41 is arranged on the upper end of the mounting plate 2, both sides of the front of the mounting plate 2 are fixedly connected to a servo motor 6, the output end of the servo motor 6 is fixedly connected to a screw rod 7, a movable plate 9 is threadedly connected to the screw rod 7, a push plate 10 is fixedly connected to one side of the movable plates 9 close to each other, a first elastic sheet 11 is fixedly connected to the lower end of the push plate 10, a cleaning plate 12 is fixedly connected to the lower end of the first elastic sheet 11, the servo motor 6 drives the screw rod 7 to rotate, the screw rod 7 drives the movable plate 9 to move, the movable plate 9 drives the push plate 10 to move forward, and pushes the cut straw to complete the unloading of the straw cutting;

[0020] By adopting the above technical solution, the lower end of the cleaning plate 12 is fixedly connected to the cleaning rod 13, and the cleaning rod 13 is adapted to the mixing and cutting table 1. Figure 1 As shown, it is used to clean the grooves of the cutting table 1.

[0021] By adopting the above technical solution, the limiting plates 14 are fixedly connected to the two sides of the front of the mounting plate 2. The limiting plates 14 are in contact with the cleaning plate 12 to lift the cleaning plate 12, so that when the cleaning plate 12 is moved for use, it is ensured that the cleaning plate 12 can drive the cleaning rod 13 to enter the cutting table 1 to avoid getting stuck and unable to be used due to misalignment.

[0022] By adopting the above technical solution, the two sides of the front of the push plate 10 are fixedly connected to the support plates 17, and the support plates 17 are fixedly connected to the second elastic sheet 15 on one side close to each other. The second elastic sheet 15 is fixedly connected to the splint 16 on one side. The splint 16 is arranged so that the push plate 10 can drive the splint 16 to move and cover the straw to prevent the straw from spreading outward after being pushed, and after being squeezed, the splint 16 can move to one side to squeeze the second elastic sheet 15 for adjustment.

[0023] By adopting the above technical solution, the front upper end of the mounting plate 2 is fixedly connected to the hydraulic cylinder 3, the lower end of the hydraulic cylinder 3 is fixedly connected to the mounting block 4, the lower end of the mounting block 4 is fixedly connected to the cutter 41, the hydraulic cylinder 3 drives the mounting block 4 to descend, and the mounting block 4 drives the cutter 41 to descend and cut the straw.

[0024] By adopting the above technical solution, the mounting block 4 is slidably connected to the pressing frame 5 on both sides, an opening is provided at the lower end of the pressing frame 5, springs 51 are fixedly connected to the upper ends of the pressing frame 5 on both sides, and the upper ends of the springs 51 are fixedly connected to the mounting block 4. The set pressing frame 5 is used to limit the position of the straw, so that when the cutter 41 descends to cut the straw, the straw will not deviate and cause uneven cutting.

[0025] The implementation principle of a straw briquetting pretreatment device in an embodiment of the present application is as follows: the stacked straw is placed on the briquetting table 1 from the front side, and then the hydraulic cylinder 3 is started, so that the hydraulic cylinder 3 drives the mounting block 4 to descend, and the mounting block 4 drives the cutter 41 to descend, and drives the pressing frame 5 to descend, and the pressing frame 5 stops moving after descending and contacting the straw, while the mounting block 4 continues to drive the cutter 41 to descend, and the squeezing spring 51 contracts, so that the cutter is exposed from the opening and cuts off the straw, and after cutting, the hydraulic cylinder 3 drives the cutter 41 and the pressing frame 5 to rise, and then the servo motors 6 on both sides are started, so that the servo motor 6 drives the screw rod 7 to rotate, and the screw rod 7 drives the moving plate 9 to move, and the moving plate 9 drives the push plate 10 to move forward and push the cut straw, and when the push plate 10 moves forward, the splint 16 covers the straw to prevent the straw from spreading outward after being pushed, and after being squeezed, the splint 16 can move to one side to squeeze the second elastic sheet 15 for adjustment.

[0026] During the forward movement of the push plate 10, the cleaning plate 12 at the lower end moves together. At the starting position, the cleaning plate 12 is supported by the limit plate 14 so that it is higher than the cutting table 1. When it continues to move and separates from the limit plate 14, the No. 1 elastic sheet 11 drives the cleaning plate 12 to move downward and lowers the cleaning rod 13, so that the cleaning plate 12 and the cleaning rod 13 are in contact with the cutting table 1, and clean and assist in pushing the straw on the cutting table 1 while driving, so that the straw can be unloaded at one time.
