Description

Technical Field

[0001] The present invention relates to the technical field related to the processing of biomass materials, and in particular to a biomass crushing and classification integrated device. Background Art

[0002] Biomass materials are a type of materials prepared by using biomass resources, and these resources mainly include organic organisms such as plants, animals, and microorganisms. In China, the sown area of rice accounts for about one-third of the total area of food crops, and rice straw is a by-product of rice, with an extremely large annual output. In the past, the utilization of rice straw has always remained at a general level, and insufficient attention has been paid to the comprehensive utilization. With the development of science and technology and the introduction of laws and regulations prohibiting the open burning of straw by the state, the comprehensive utilization of rice straw has begun to be gradually taken seriously and promoted, and the main application directions are fertilizers, animal husbandry, edible fungi, energy, processing industries, etc., especially in the recycling and processing of biomass materials. And a crushing device is usually required during production. Refer to the publication number: "CN213032622U", the disclosed "a biomass crushing device" includes a box body, the top of the box body is fixedly connected with a feed inlet, the four corners of the bottom of the box body are respectively connected with a base, two screws are respectively rotatably connected to the left and right sides of the outer wall of the box body through bearings, first grooved wheels are fixedly connected to the outer sides of the two screws, sleeves are threadedly connected to the outer walls of the two screws, sliding plates are fixedly connected to the tops of the two arc-shaped plates, and the outer walls of the arc-shaped plates and the sliding plates are in clearance fit with the inner wall of the box body.

[0003] Existing crushing devices usually require manual unpacking during use, and then the sorted rice straw is put into the crushing device. After unpacking, the structure of the rice straw is loose, and the feeding speed usually cannot be effectively controlled. Therefore, the size after crushing cannot be effectively controlled during crushing, and some rice straw is prone to excessive crushing resulting in too small particle size, which is not conducive to subsequent fermentation work and will generate a large amount of dust pollution. Therefore, there are drawbacks during use. Summary of the Invention

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present invention is to provide a biomass crushing and classification integrated device to solve the problems that the existing crushing device relies on manual unpacking and cannot well control the crushing size during processing mentioned in the above background.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A biomass crushing and classification integrated device, including a chassis, a bracket and a bale opener housing.

[0010] Further, two third conveying devices are symmetrically distributed at both ends inside the bale opener housing. A baffle is installed at one end inside the bale opener housing, and the two baffles are symmetrically distributed. A hook is installed on each baffle.

[0011] Further, a fixer is installed on the upper side of the bale opener housing near the baffle, and a second cutter is installed at the bottom of the fixer. A spring plate is installed inside the fixer, and one end of the spring plate is snap-connected to the top of the second cutter. At the same time, the second cutter and the spring plate form a resilient structure.

[0012] Further, a belt drive structure is installed on the outer wall of one side of the middle shell, and the belt drive structure is simultaneously connected to the two conveying rollers in a driving manner.

[0013] Further, the upper part of the feed bin is of a converging structure.

[0014] Further, both the middle shell and the inner shell are of an open structure near the guiding cover. Two brush blocks are symmetrically distributed on both sides inside the inner shell. The guiding cover is inclined and has a funnel-shaped structure.

[0015] Furthermore, the connection mode between the outer shell and the inner cylinder is a rotational connection. A first gear transmission structure is installed at the lower part of the outer wall of the outer shell, and the first gear transmission structure is in transmission connection with the inner cylinder.

[0016] Furthermore, the axis lines of the end shell, the inner cylinder, and the outer shell are all on the same straight line. The end shell has a funnel-shaped structure, and the interior of the end shell is in communication with the interior of the inner cylinder.

[0017] Furthermore, the axis lines of the pressure shell, the expansion ring, and the end shell are all on the same straight line. Both sides of the expansion ring are snap-fitted to the inner wall of the pressure shell;

[0018] Furthermore, the expansion ring, the pressure shell, and the control air pump form an expansion structure.

[0019] Furthermore, the axis lines of the joint, the rotating cylinder, and the joint are all on the same straight line. A second gear transmission structure is installed on the outer wall of the joint, and the second gear transmission structure is in transmission connection with the rotating cylinder;

[0020] Furthermore, a spiral flange structure is provided on the inner wall of the rotating cylinder.

[0021] Furthermore, the air cylinder and the first cutter form a telescopic structure. One side of the first cutter is closely attached to the end of the joint, and a "V"-shaped slot is provided at the end of the first cutter.

[0022] Furthermore, an absorption box is installed at one end of the bottom of the outer shell of the unpacking device close to the second cutter, and the bottom of the absorption box is in communication with one end of a connecting pipe; the other end of the connecting pipe is in communication with a storage box for impurities. The storage box for impurities is installed at the bottom of the outer shell of the unpacking device, and a filtering air blower is installed at the bottom of the storage box for impurities.

[0023] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0024] 1. In the present invention, a bale opener housing, a hook, and a second cutter are provided. Inside the bale opener housing, two third conveying devices running in the same direction are installed. The minimum distance between the two third conveying devices is fixed. After a single bundle of rice straw is fed between the two third conveying devices from one end, it will start to be conveyed under the clamping of the two third conveying devices. Since the binding rope for restricting the rice straw is wrapped around the outside of the rice straw in a ring shape, during the conveying process, the second cutter with barbs will hook and cut the ring-shaped binding rope. Subsequently, both ends of the binding rope will be blocked by the hooks on both sides and stop following the rice straw for further conveyance. Then, under the action of the filtering fan, the absorption box maintains a negative pressure state. After being cut, the binding rope will fall and be absorbed into the absorption box, and finally be temporarily stored in the impurity storage box. Compared with the traditional manual bale opening process, the bale opening efficiency, that is, the conveying efficiency, is improved.

[0025] 2. In the present invention, a feed bin, a second conveying device, and a guiding cover are provided. Inside the feed bin, two conveying rollers are provided. The cross-section of each conveying roller is in a plum blossom shape structure, and the two conveying rollers are parallel and closely distributed, and the two conveying rollers synchronously rotate in opposite directions. The rice straw in contact is clamped through the grooves between the two conveying rollers and intermittently fed into the inner shell. Then, the conveying direction of the rice straw is changed through the second conveying device, and the feeding speed can be controlled by controlling the rotation speed of the conveying rollers.

[0026] 3. In the present invention, an inner cylinder, a baffle, an end shell, a pressure shell, an expansion ring, and a rotating cylinder are provided. Inside the inner cylinder, a baffle extending into the end shell is provided. The inner cylinder is driven by a second gear transmission structure to rotate slowly as a whole. Since the rice straw is fed into the inner cylinder in small amounts in sequence, and the inclined inner cylinder cooperates with the funnel-shaped end shell, the lower ends of the rice straw will be concentrated together, while the upper ends of the rice straw will disperse around. In the initial stage, the air pump is controlled to inflate the pressure shell to make the expansion ring expand and clamp the lower ends of the rice straw, giving a certain frictional force to the lower-end rice straw. Subsequently, the rear end of the rice straw gradually rotates and is twisted together in a spiral shape under the action of the rotating inner cylinder and the baffle. When the lower-end rice straw is tightened, the expansion ring is released, and at the same time, the rotating cylinder is started. Through the spiral flange structure inside the rotating cylinder, the tightened rice straw is slowly pushed outwards. At the same time, the subsequent incoming rice straw continues to be woven together with the front-end rice straw and slowly pushed out from the joint end. Since the density of the woven rice straw is relatively large and the pushing-out speed is constant, by controlling the single reciprocating speed of the second cutter, the cutting length of the rice straw can be effectively controlled. And compared with the crushing device with a wheel cutter, the dust pollution is greatly reduced, and the overall practicality is improved.

[0027] To more clearly illustrate the structural features and functions of the present invention, the present invention will be described in detail below in conjunction with the drawings and specific embodiments. Description of the Drawings

[0077] Working principle of the present invention: When in use, first connect to an external power supply, and at the same time start two third conveying devices 27, and put the bundled rice straw into the unpacker housing 26. The two third conveying devices 27 clamp and start to convey the rice straw. During the conveying process, the binding ropes wrapping the rice straw are cut by the second cutter 31.

At this time, the first gear drive structure 15 is started to drive the inner cylinder 13 to drive the baffle 14 to rotate slowly synchronously. Subsequently, the control air pump 19 is started to pressurize the pressure shell 17, causing the expansion ring 18 to expand and clamp the lower end of the passing rice straw, increasing the friction force on the lower end of the rice straw.

Subsequently, the second gear drive structure 22 is started to drive the rotating cylinder 21 to start rotating slowly, assisting in pushing the knotted rice straw to slowly discharge outwards. Subsequently, the cylinder 24 is started to push the first cutter 25 to cut the passing rice straw. The cut rice straw will naturally fall on the first conveying device 2. The first conveying device 2 is started to continue conveying the shredded rice straw.

[0079] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention.
