Description

Technical Field

[0001] This utility model relates to the technical field of biomass processing, specifically to a device for crushing, baling, and rolling biomass straw. Background Technology

[0002] Crop straw, a type of biomass, can be used as a raw material for producing green methanol. Biomass-to-methanol is a sustainable method that utilizes biomass resources to convert them into methanol through a series of technologies. The main processes include biomass gasification synthesis and bio-fermentation. Biomass gasification synthesis involves gasification, purification, and synthesis. Gasification converts biomass into syngas under high temperature and oxygen-deficient conditions, the main components of which are carbon monoxide, hydrogen, and carbon dioxide. Purification removes impurities from the syngas, such as tar, sulfides, and dust, to prevent catalyst poisoning during subsequent synthesis. Synthesis, under specific temperature, pressure, and catalyst conditions, causes the purified syngas to react and produce methanol. Biomass-to-methanol reduces dependence on fossil fuels and lowers emissions of greenhouse gases such as carbon dioxide, contributing to mitigating global warming. Crop straw is renewable; as long as there is sunlight, water, and land, energy crops can be continuously planted, and agricultural and forestry waste and urban organic waste will continue to be generated, providing a continuous supply of raw materials for methanol production.

[0003] Crop straw is a raw material that is scattered, bulky, and low in density. It is seasonal every year and needs to be collected in a storage yard. However, the collected crop straw takes up a lot of space. Therefore, it is best to crush and bale the crop straw before stacking it to reduce the area occupied by the crop straw.

[0004] In the field of crop straw crushing and baling technology, Chinese invention patent No. 201710415769.3 discloses a straw crushing and baling machine and a straw crushing and baling system. The straw crushing and baling machine includes a drive device, a harvesting device, a conveying device, a baling device, and a frame. The frame is provided with a feeding inlet, and the harvesting device is installed on the frame and connected to the feeding inlet. Straw enters the harvesting device through the feeding inlet, and the harvesting device is connected to the baling device through the conveying device.

[0005] In addition, Chinese utility model patent with patent number 201820269375.1 discloses a straw crushing and baling machine, including a harvesting mechanism, a conveyor belt mechanism, and a baling mechanism. The upper rear side of the harvesting mechanism is connected to the baling mechanism, and the upper part of the harvesting mechanism is also connected to the baling mechanism through a diagonal tie rod. A traction frame is provided on the upper front side of the harvesting mechanism, and a roller is installed on the rear bottom side of the harvesting mechanism through a bracket. The harvesting mechanism has a blade assembly located on the front side and a conveying assembly located on the rear side inside. The conveyor belt mechanism is located between the material outlet of the harvesting mechanism and the material inlet of the baling mechanism. Both ends of the conveyor belt mechanism are connected to the harvesting mechanism and the baling mechanism respectively, and the power input end of the conveyor belt mechanism is connected to the sprocket and chain drive assembly of the baling mechanism for power input.

[0006] Furthermore, Chinese utility model patent number 201921471439.7 discloses a straw crushing and baling machine. The machine body is divided into a crushing chamber and a baling chamber by a partition. The crushing device includes a first cutter roller and a second cutter roller, which are arranged horizontally and parallel to each other within the crushing chamber. The baling device includes a first electro-hydraulic telescopic rod and a pressure plate. The first electro-hydraulic telescopic rod is vertically fixed at the upper end of the baling chamber, and the pressure plate is horizontally fixed at the lower end of the first electro-hydraulic telescopic rod. The pushing device includes a second electro-hydraulic telescopic rod and a U-shaped block. The second electro-hydraulic telescopic rod is horizontally arranged within the crushing chamber, and the U-shaped block is inserted into the baling chamber. The side of the U-shaped block is fixedly connected to the piston rod of the second electro-hydraulic telescopic rod.

[0007] After being crushed and baled, crop straw in the storage yard is susceptible to damage from rainfall. Rainwater can easily cause mold growth and hinder the biomass gasification process for methanol production. Therefore, waterproofing crushed and baled crop straw is a technical problem that needs to be solved. Summary of the Invention

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and to provide a biomass crushing, baling and wrapping integrated machine.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A biomass crushing, baling, and wrapping integrated machine includes a straw crusher for crushing straw and a straw baler for baling straw. The straw crusher is installed at the front end of the straw baler to transport the crushed straw into the straw baler. It also includes a wrapping device installed at the rear end of the straw baler. The wrapping device includes a flat plate, a base, a turntable, and a film roll. The flat plate is located at the straw bale discharge outlet of the straw baler. The base is mounted on the flat plate. The turntable is mounted in the middle of the base via bearings. The film roll is vertically mounted at one end of the base via bearings, and the film roll is fitted with a film for wrapping the bales of straw.

[0011] By adopting the above technical solution, the straw crusher crushes the straw and then conveys it to the straw baler via a conveyor belt. The straw baler compresses the straw into shape and then conveys it to the turntable of the wrapping device. The turntable is on the base for easy rotation. Then, one end of the film is pulled up to wrap the baled straw. Cutting the film completes the wrapping of the crop straw. The film serves to waterproof the straw.

[0012] Preferably, it also includes wheels, which are installed at the bottom of the straw baler housing.

[0013] By adopting the above technical solution, the straw crusher and straw baler are integrated into one design, and with the addition of wheels, they can be moved for operation.

[0014] Preferably, protective plates are installed at both ends of the flat plate.

[0015] By adopting the above technical solution, the protective plate can prevent the turntable from rotating too fast, causing the bundles of straw to slip off the turntable in the left and right directions.

[0016] Preferably, two limiting blocks are sleeved on the film roll, and the two limiting blocks are locked to the film roll by limiting pins, with the film located between the two limiting blocks.

[0017] By adopting the above technical solution, the two limiting blocks can be adapted to films of different widths and can lock the film at any position on the film roll.

[0018] Preferably, the film is a waterproof and breathable film.

[0019] By adopting the above technical solution, the waterproof and breathable membrane has a unique microporous structure with extremely small pore sizes, generally between 0.2 and 10 micrometers. These micropores are smaller than the smallest diameter of a water droplet but larger than the diameter of a water vapor molecule. Therefore, water droplets cannot pass through these micropores, while water vapor molecules can freely diffuse through them, thus achieving the function of waterproofing and breathability. Wrapping baled straw with this waterproof and breathable membrane allows water vapor to pass through in one direction while preventing rain from penetrating, allowing the crop straw to remain dry in the future.

[0020] Compared with related technologies, the biomass crushing, baling and wrapping integrated machine provided by this utility model has the following beneficial effects:

[0021] 1. The straw crusher and straw baler of this utility model adopt an integrated design, which can crush and bale crop straw and stack it, reducing the space occupied by crop straw.

[0022] 2. The wrapping device of this utility model can wrap crushed and baled straw with film, which has the function of being waterproof and breathable, preventing the straw from getting damp and moldy. During the wrapping process, the bundled straw can rotate freely on the turntable, and the film can also rotate freely on the film roll, which significantly reduces the difficulty of film wrapping operation.

The straw crusher 10 is installed at the front end of the straw baler 20, and the crushed straw is conveyed into the straw baler 20 via a conveyor belt. The straw baler 20 is used to compress the crushed straw into cylindrical bundles. The straw baler 20 has a bundled straw discharge outlet on the side away from the straw crusher 10. The wrapping device 30 is used to wrap the crushed and baled straw with a film 306. The film 306 is a waterproof and breathable film, which has the function of waterproofing and moisture permeability, preventing the straw from getting damp and moldy, and allowing the bundled straw inside the film 306 to remain dry.

[0032] Specifically, the wrapping device 30 is installed at the rear end of the straw baler 20. The cylindrical bundles of straw produced by the straw baler 20 are pushed into the wrapping device 30 for wrapping. The wrapping device 30 includes a flat plate 301, a base 302, a turntable 303, and a film roll 304. One end of the flat plate 301 is fixed to the straw baler 20, and the flat plate 301 is located at the straw discharge outlet of the straw baler 20, allowing the bundles of straw pushed out of the discharge outlet to slide onto the flat plate 301.

The film roll 304 is fitted with a film 306 for wrapping bundles of straw.

[0033] In operation, the straw baler 20 pushes the baled straw onto the disc, pulls one end of the film 306 and wraps it around the straw until the film 306 completely covers the straw, then cuts the film 306 and unloads the wrapped straw from the turntable 303, completing the film wrapping operation. The operation is simple.

[0034] The above are merely preferred embodiments of this utility model and do not limit the implementation methods and protection scope of this utility model. Based on the above, this invention also has the following embodiments:
