Description

Technical Field

[0001] The utility model relates to the technical field of straw briquetting machines, in particular to a straw crushing and briquetting machine. Background Technique

[0002] Entering the 21st century and with the continuous development of China's social economy, China's agricultural industry has made great progress, and the annual agricultural output has been increasing. However, the problems that follow have also emerged. In particular, a large amount of straw is left over after the harvest of some crops and is difficult to handle. Some are directly burned in the fields, which not only wastes resources but also causes environmental pollution. Therefore, we need to make full use of straw. In current agricultural production, as a common agricultural waste, the treatment and utilization of straw have always been a research hotspot. In order to effectively utilize straw resources and reduce environmental pollution, the crushing and briquetting treatment of straw is particularly important. 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.

[0003] Among them, the patent with the application number CN210352258U discloses a straw crushing and briquetting machine, which has solved various disadvantages such as incompletely crushed straw directly falling into the briquetting area, poor extrusion effect, and the need for manual removal of the formed straw blocks, resulting in low work efficiency. After further retrieval, it is found that the "corn straw crushing and briquetting machine" disclosed in the patent with the application number "CN215882704U" effectively solves the problems of the corn straw crushing and briquetting machine, such as the problem of inconvenient storage of the briquettes through specific technical structure settings. However, in actual use, straw briquetting machines with similar structures still have many defects. For example, currently on the market, after straw is crushed, it needs to be briquetted by a briquetting machine. Although the briquetting of straw is achieved to a certain extent, the briquetted straw blocks cannot be conveniently exported, which is rather inconvenient during use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a straw crushing and briquetting machine to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A straw crushing and briquetting machine, comprising a support base and a telescopic rod. A support block is fixedly installed at the top of the support base. A buffer movable plate is movably installed at the top of the support block through a sliding block. Activity rods are fixedly installed on both sides of the support base. A top plate is fixedly installed at the top of the activity rods. A bearing plate is movably installed at the top of the buffer movable plate inside the activity rods. A material pressing block corresponding to the forming die box is movably installed at the bottom of the top plate. Telescopic rods for pushing the forming die box are fixedly installed at the top of the support base on both sides of the activity rods. Through the extrusion action of the hydraulic cylinder, the material pressing block can move downward, enabling the movable block to slide along the outer side of the activity rod. The anti-leakage plate can prevent the added crushed straw from leaking. The material pressing block can perform a briquetting operation on the crushed straw inside the forming die box.

[0006] Preferably, a sliding groove matching with the sliding block is formed inside the support block, and the bottom of the support block and the buffer movable plate are movably connected through a buffer spring. Through the mutual sliding between the sliding groove and the sliding block, the buffer movable plate can slide along the inside of the support block during the extrusion process, thereby squeezing the buffer spring to achieve the purpose of buffering.

[0007] Preferably, a lower pushing block is fixedly installed at the top of the telescopic rod, upper pushing blocks corresponding to the lower pushing block are fixedly installed on both sides of the forming die box, and an activity groove matching with the activity rod is formed inside the lower pushing block. The telescopic rod can drive the lower pushing block to move upward, enabling the lower pushing block to contact and squeeze the upper pushing block, so that the forming die box can be pushed upward, and the briquetted straw block inside the forming die box can be exported to the top of the bearing plate.

[0008] Preferably, upper pushing blocks are fixedly installed on both sides of the forming die box, and the upper pushing blocks are movably installed between the activity rods. Through the upper pushing blocks, it is convenient to dock with the lower pushing block, enabling the lower pushing block to squeeze the upper pushing block during the telescopic process of the telescopic rod. At the same time, the lower pushing block can be separated from the upper pushing block, which can prevent the telescopic rod from being damaged during the extrusion process between the material pressing block and the forming die box.

[0009] Preferably, an anti-leakage plate is fixedly installed at the top of the bearing plate, and the anti-leakage plate corresponds to the forming die box. The anti-leakage plate can conveniently prevent the added crushed straw from leaking. At the same time, it can provide effective protection during the extrusion process. Also, through the correspondence between the forming die box and the anti-leakage plate, the crushed straw can be filled inside the forming die box.

[0010] Preferably, the material pressing block is movably connected to the top plate through a hydraulic cylinder, and the material pressing block is movably connected to the movable rod through a movable block. The hydraulic cylinder can conveniently push the material pressing block, so that the material pressing block can slide along the outside of the movable rod, so that the bottom of the material pressing block contacts the forming die box for extrusion. At the same time, the movable block can increase the stability effect during the up and down sliding of the material pressing block.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] 1. By the mutual cooperation among the material pressing block, the forming die box, the anti-leakage plate and the bearing plate in the present utility model, the crushed straw is added into the forming die box. Through the extrusion action of the hydraulic cylinder, the material pressing block can move downward, and the movable block slides along the outside of the movable rod. The anti-leakage plate can prevent the added crushed straw from leaking, and the material pressing block can press the crushed straw inside the forming die box. The operation is convenient and fast during use.

[0013] 2. By the mutual cooperation among the lower pushing block, the upper pushing block, the telescopic rod, the movable groove and the buffer movable plate in the present utility model, after extrusion, the telescopic rod can drive the lower pushing block to move upward, so that the lower pushing block can contact and extrude the upper pushing block, and the forming die box can be pushed upward, so that the straw blocks pressed and combined inside the forming die box can be exported to the top of the bearing plate. At the same time, during extrusion, the buffer movable plate can slide along the inside of the sliding groove, so that the bottom of the buffer movable plate can be extruded with the buffer spring, which can effectively buffer during extrusion and is more convenient to use.
