Description

Technical Field

[0001] This utility model belongs to the field of biomass power generation technology, and in particular relates to a straw shredding device for biomass power generation. Background Technology

[0002] Biomass power generation, as a renewable energy utilization method, plays an important role in promoting the transformation of energy structure and achieving the goal of carbon neutrality. Due to its wide availability and low cost, baled straw has become one of the important raw materials for biomass power generation, which can effectively solve the environmental pollution problem caused by straw burning and realize the recycling of resources.

[0003] However, existing technologies for crushing bundled straw have significant shortcomings. Specifically, current straw crushing devices on the market, when processing bundled straw, often use machines to bale it into a cylindrical shape during recycling. This unique shape makes it difficult to place stably within the crushing device. When the bundled straw is fed into the crushing device, it rolls continuously inside, only being contacted and crushed by the crushing blades when it reaches a specific angle. As raw materials are continuously fed in, uncrushed bundled straw accumulates within the crushing device, not only reducing crushing efficiency but also easily causing equipment blockage, seriously affecting the stability of raw material supply and power generation efficiency for biomass power generation.

[0004] Therefore, there is an urgent need to design a device that can effectively solve the problem of straw breakage in bundling to meet the actual needs of the biomass power generation industry. Utility Model Content

[0005] The purpose of this invention is to provide a bundled straw crushing device for biomass power generation, which addresses the problems of low crushing efficiency and easy equipment blockage caused by the difficulty in stable crushing of cylindrical bundled straw when the existing straw crushing devices are used to process it.

[0006] The present invention achieves the above objectives through the following technical solution: a baled straw crushing device for biomass power generation, comprising a crusher, a baled straw conveyor provided on one side of the crusher, an automatic cutter provided on one side wall of the baled straw conveyor, and a crushed straw conveyor belt provided at the bottom of the crusher;

[0007] The straw baling conveyor includes a conveying frame. Two sets of conveying guide rails are arranged opposite each other on the upper surface of the conveying frame. A conveying rack is provided at one of the conveying guide rails. Conveying sliders are slidably arranged on both sets of conveying guide rails. A conveying platform is fixedly arranged between several conveying sliders. A conveying motor is arranged in the cavity of the conveying platform. A conveying gear is arranged through the rotating shaft of the conveying motor and meshes with the conveying rack. An extension rod is fixedly arranged on the top of the conveying platform, and a pusher head is provided at the end of the extension rod.

[0008] Two sets of material placement components are provided on the conveying frame located at one end of the two sets of conveying guide rails.

[0009] Furthermore, the crusher includes a crusher body with openings at the top and bottom. A driving blade and a driven blade are rotatably arranged inside the crusher body cavity. A crushing motor is provided at one end of the driving blade to drive its rotation, and a driving gear is provided at the other end of the driving blade. A driven gear is provided at one end of the driven blade, and the driving gear meshes with the driven gear.

[0010] Furthermore, the conveyor motor is fixedly installed in the conveyor table cavity by a shock-absorbing pad, which is made of rubber and has a thickness of 5-10mm.

[0011] Furthermore, the pusher head has a circular structure, and the surface of the pusher head is provided with wear-resistant texture.

[0012] Furthermore, the material feeding assembly includes two sets of bearing bases arranged opposite each other, bearings are provided in the bearing bases, and grooved rollers are rotatably arranged between the two sets of bearings.

[0013] Furthermore, the bottom of the crusher is provided with a funnel-shaped discharge port, the crushed straw conveyor belt is located directly below the discharge port, and the width of the crushed straw conveyor belt is greater than the width of the discharge port.

[0014] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0015] 1. Optimized pre-cutting process: By installing an automatic cutter on the side wall of one end of the straw conveyor, the straw can be cut before entering the crusher, dividing the cylindrical bundled straw into small segments. This prevents the whole material from rolling inside the crusher, ensuring that the straw can be crushed in a timely and stable manner, and significantly improving the crushing efficiency.

[0016] 2. Stable conveying and anti-accumulation: The conveying frame of the straw baling conveyor is equipped with two sets of conveying guide rails and conveying racks. Together with the conveying platform driven by the conveying motor and the pusher head, it can orderly feed the straw into the crusher. At the same time, the material placement component assists in placing the straw, effectively avoiding the accumulation of materials caused by the input of straw, and ensuring the continuity and stability of the conveying process.

[0017] 3. High-efficiency crushing design: The crusher is equipped with a driving blade and a driven blade that work together. Through the meshing of the driving gear and the driven gear, the two blades work together to crush the straw. Compared with single-blade crushing, the straw can be crushed faster and more thoroughly, which further improves the crushing effect and efficiency.

[0018] 4. Optimized discharge process: The bottom of the crusher is equipped with a funnel-shaped discharge port, and the crushed straw conveyor belt is located directly below the discharge port. Its width is greater than that of the discharge port, which is conducive to the rapid and smooth discharge of crushed straw, avoiding residue accumulation at the bottom of the crusher and ensuring the efficient operation of the crushing device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Combination Figure 1-4 The device shown is a baled straw crushing device for biomass power generation. Its core structure includes a crusher 1, which serves as the core crushing part of the entire device and provides a stable and reliable working environment for straw crushing. A baled straw conveyor 2 is installed adjacent to one side of the crusher 1. This part undertakes the important task of smoothly and orderly conveying the baled straw to the crusher 1. An automatic cutter 3 is installed on one side wall of the baled straw conveyor 2. The automatic cutter 3 can automatically adjust the cutting parameters according to the size of the baled straw. When the baled straw is conveyed to the designated position, the automatic cutter 3 starts and cuts the straw into a suitable crushing length, effectively solving the problem that baled straw is difficult to crush due to its special shape. A straw crushing conveyor belt 4 is installed at the bottom of the crusher 1. The straw crushing conveyor belt 4 can flexibly adjust the conveying speed according to the actual production needs to ensure that the crushed straw can be conveyed to the next process in a timely and efficient manner.

[0029] Furthermore, the straw baling conveyor 2 includes a conveying frame 201, which serves as the supporting skeleton of the entire conveying mechanism. The conveying frame 201 is welded from high-strength rectangular steel pipes, possessing extremely high structural strength and stability, and capable of withstanding large loads. Two sets of conveying guide rails 202 are arranged opposite each other on both sides of the upper surface of the conveying frame 201. These two sets of conveying guide rails 202 are high-precision linear guide rails, ensuring the smoothness and accuracy of the conveying process. A conveying rack 203 is located at one of the conveying guide rails 202. Conveying sliders 204 are slidably mounted on both sets of conveying guide rails 202, and several conveying sliders 204 are fixed together. A conveyor table 205 is provided, and a conveyor motor 206 is installed inside the cavity of the conveyor table 205. The conveyor motor 206 is a high-performance variable frequency motor with advantages such as smooth start-up, wide speed range and reliable operation. The rotating shaft of the conveyor motor 206 passes through the conveyor table 205 and a conveyor gear 207 is provided. The conveyor gear 207 meshes with the conveyor rack 203. The conveyor motor 206 drives the conveyor gear 207 to roll on the conveyor rack 203, thereby driving the conveyor table 205 to make linear reciprocating motion along the conveyor guide rail 202. An extension rod 208 is fixedly provided on the top of the conveyor table 205, and a pusher head 209 is provided at the end of the extension rod 208.

[0030] Two sets of material placement components 2010 are installed on the conveying frame 201 located at one end of the two sets of conveying guide rails 202. The material placement components 2010 can conveniently place and bundle straw, ensuring that the straw can be accurately conveyed to the cutting and crushing position, thereby improving the working efficiency and stability of the entire device.

[0031] In this embodiment, the crusher 1 includes a crusher body 101 with openings at the top and bottom. The interior of the crusher body 101 is processed to form a smooth and wear-resistant crushing chamber. The opening design of the crusher body 101 at the top and bottom ensures smooth entry and exit of straw, improving material flow efficiency. A driving blade 102 and a driven blade 103 are rotatably arranged inside the crusher body 101. The blade teeth are arranged in an interlaced design, which can generate strong tearing force when rotating. A crushing motor 104 is provided at one end of the driving blade 102 to drive its rotation. The crushing motor 104 and the driving blade 102 are connected by a high-precision coupling to ensure stable and reliable power transmission and reduce vibration and noise. A driving gear 105 is provided at the other end of the driving blade 102, and a driven gear 106 is provided at one end of the driven blade 103. The driving gear 105 and the driven gear 106 mesh to form an efficient and stable gear transmission system, which can accurately transmit the power of the driving blade 102 to the driven blade 103, so that the two work together with a suitable speed difference to achieve efficient crushing of straw.

[0032] In this embodiment, the conveyor motor 206 is fixedly installed in the cavity of the conveyor platform 205 by a shock-absorbing pad. The shock-absorbing pad is made of rubber and its thickness is designed to be 5-10mm. This installation method can significantly reduce the transmission of vibration generated by the conveyor motor 206 during operation to the conveyor platform 205 and the entire conveying mechanism, effectively reduce equipment operating noise, extend the service life of components such as the conveyor motor 206 and the conveyor platform 205, and improve the stability and reliability of the straw bundling and conveying process.

[0033] In this embodiment, the pusher head 209 has a circular structure. The circular structure design makes the force on the pusher head 209 more uniform during the process of pushing and bundling straw, avoiding stress concentration. The surface of the pusher head 209 is provided with wear-resistant texture to ensure that the straw is not easy to slip during the pushing process, thus achieving stable pushing.

[0034] In this embodiment, the feeding assembly 2010 includes two sets of bearing bases 20101 arranged opposite to each other. The bearing bases 20101 are made of high-strength cast steel and are integrally formed by precision casting. Bearings 20102 are installed inside the bearing bases 20101. A grooved roller 20103 is rotatably arranged between the two sets of bearings 20102. The outer circumference of the grooved roller 20103 is provided with an annular groove. The depth and width of the groove are precisely designed to match the shape and size of the bundled straw, which can firmly hold the straw and ensure that it will not be displaced or fall off during the subsequent conveying process. In addition, the grooved roller 20103 can rotate flexibly under the support of the bearings 20102. When the conveying table 205 drives the pusher head 209 to push the straw, the grooved roller 20103 can rotate accordingly to assist the straw to move smoothly. At the same time, it provides precise guidance for the straw to enter the subsequent conveying and cutting processes, improving the working efficiency and reliability of the entire device.

[0035] In this embodiment, the bottom of the crusher 1 is provided with a funnel-shaped discharge port, and the crushed straw conveyor belt 4 is located directly below the discharge port. The width of the crushed straw conveyor belt 4 is greater than the width of the discharge port. This design effectively avoids the situation where the crushed straw spills to the outside of the crushed straw conveyor belt 4 during the discharge process. At the same time, it provides a certain buffer space for the distribution of straw on the crushed straw conveyor belt 4, preventing the straw from accumulating locally on it, ensuring the continuity and efficiency of straw conveying, and providing a reliable guarantee for the subsequent processing of biomass power generation raw materials.
