Description

Technical Field

[0001] This utility model belongs to the field of straw crushing technology, and in particular relates to a rice paddy straw crushing device. Background Technology

[0002] In agricultural production, the scientific treatment of paddy field straw is an important link in ensuring the quality of arable land and promoting the sustainable development of agriculture. At present, straw return to the field is the mainstream treatment method, which can not only reduce the environmental pollution caused by burning, but also increase soil organic matter and improve soil structure through straw decomposition. However, existing paddy field straw crushing equipment still has many limitations in practical applications.

[0003] However, when existing crushing equipment stops operating, the crushing blades lose centrifugal support and suddenly become unstable due to their own gravity and inertia. This can easily lead to disordered swaying or even violent shaking, often resulting in hard collisions with the inner wall of the equipment and other components. This can cause minor issues such as curled edges and chips on the blades, or even deformation and breakage of the blade body. Utility Model Content

[0004] The purpose of this utility model is to provide a rice straw crushing device. By setting up a crushing section, it solves the problem that when existing crushing equipment stops operating, the crushing blades lose centrifugal support and suddenly lose stability under their own gravity and inertia, which easily leads to disordered swinging or even violent shaking. This often results in hard collisions with the inner wall of the equipment and other parts, which can cause minor issues such as curled edges and chips on the blades, or even deformation and breakage of the blades.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rice straw crushing device, comprising a support plate and a conveying assembly mounted on the support plate. Its distinguishing feature is that it further includes: a crushing section mounted on the support plate; an anti-clogging section mounted on the support plate; the crushing section includes a transmission assembly mounted on the support plate; and a plurality of hinge assemblies, each mounted on the transmission assembly; the transmission assembly includes a fixed box fixedly connected to the right side of the support plate, a rotating shaft rotatably connected to the inner wall of the fixed box, a circular roller fixedly connected to the outer wall of the rotating shaft, and two fixed discs fixedly connected to the circular roller. A turntable is fixedly connected to the left side of the fixed box, and a limiting component is provided on the turntable. A power component is provided on the front side of the fixed box. A rotating shaft passes through the fixed box, which is n-shaped. The limiting component includes a fixed plate rotatably connected to the outer wall of the rotating shaft. A spring is rotatably connected to the outer wall of the rotating shaft. The right side of the spring is fixedly connected to the fixed plate, and the left side of the spring is fixedly connected to the turntable. The contact surface between the fixed disc and the fixed plate is treated with friction to increase friction. The power component includes a motor fixedly connected to the front side of the fixed box. The output shaft of the motor is coaxially arranged with the rotating shaft through a coupling. The motor is fixedly connected to the fixed box through a bracket.

[0007] Furthermore, the anti-blocking part includes an adjustment component, of which two are provided and both are mounted on the support plate; and a loosening component, which is disposed on the adjustment component; wherein the loosening component is located between the two adjustment components, and the buffer includes a second spring disposed in the slide rail, the right side of the second spring being fixedly connected to a second slider, and the left side of the second spring being fixedly connected to a first slider; wherein the initial state of the second spring is the natural state.

[0008] Furthermore, the hinge assembly includes several hinge blocks fixedly connected to the outer wall of the roller. Each hinge block has a pulverizing blade hinged to its side away from the rotating shaft. A limit rod is fixedly connected between the two fixed discs, and a slide rod is provided between the two fixed discs. The right side of the slide rod is fixedly connected to the fixed disc located on the right side. A sliding groove is opened on the fixed disc, and the left side of the slide rod passes through the sliding groove. The left side of the slide rod is fixedly connected to the fixed plate. The several hinge blocks and the pulverizing blades are all arranged in a linear array. The pulverizing blades are L-shaped, the limit rods are in contact with the several pulverizing blades, and the sliding grooves are arc-shaped.

[0009] Furthermore, the adjustment assembly includes a slide rail fixedly connected to the top of the support plate, a threaded rod threadedly connected to the slide rail, the front side of the threaded rod extending outside the slide rail, a slider one fixedly connected to the right side of the threaded rod, the slider one slidably connected to the inner wall of the slide rail, a slider two slidably connected inside the slide rail, a buffer element provided inside the slide rail, and hinge rods hinged to both the slide rail and the slider two; wherein, the two hinge rods are connected in an inverted V shape, and the sides of the two hinge rods away from the slide rail are hinged together.

[0010] Furthermore, the loosening component includes a second rotating shaft mounted on a hinged rod, and a loosening roller is fixedly connected to the outer wall of the second rotating shaft; wherein, a plurality of loosening rods are mounted on the loosening roller and are arranged in an array.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a crushing section, when the equipment is running, the motor drives the rotating shaft and related components to rotate synchronously. The crushing blades naturally extend on the hinge block with the help of centrifugal force, ensuring full contact with the straw to complete the crushing operation. After the machine stops, as the centrifugal force gradually disappears, the crushing blades only swing slightly within the range formed by the limit rod and the sliding rod, avoiding random shaking in an unrestrained state. After the crushing blades come to a complete stop, the sliding rod can be manually pulled to slide in the groove and contact the crushing blades. At this time, the sliding rod and the limit rod form a double limit structure, firmly fixing the position of the crushing blades. After the machine stops, the double protection of "natural limit swing + active fixed limit" not only avoids the crushing blades from colliding randomly due to the sudden loss of centrifugal force, but also completely eliminates the problem of blades colliding with each other when idle through the cooperation of the sliding rod and the limit rod. This effectively reduces damage such as blade edge curling and cracking, extends the service life of the crushing blades, reduces equipment maintenance costs, and improves the safety of the equipment when idle.

[0013] 2. By setting up an anti-blocking section, the conveying assembly stably conveys the straw to the right, first flattening the straw, and at the same time using its own structure to block excessively thick straw, reducing the risk of blockage in the fixed box from the source; when encountering taller straw, the loosening roller can be raised upward by changing the angle of the hinge rod, driving the second slider to slide in the slide rail and stretch the second spring. The elastic potential energy of the second spring enables adaptive adjustment for straw of different thicknesses and heights. Through the flattening of the loosening roller, the blockage problem caused by excessively thick straw directly entering the crushing area is avoided, ensuring the continuous and stable operation of the equipment.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-7 As shown, this utility model is a rice straw crushing device, including a support plate 111 and a conveying assembly 112 disposed on the support plate 111, and also includes: a crushing part 2, which is installed on the support plate 111; and an anti-blocking part 3, which is disposed on the support plate 111.

[0028] The anti-clogging part 3 includes an adjustment assembly 31, of which two are provided and both are mounted on the support plate 111; and a loosening assembly 32, which is disposed on the adjustment assembly 31. The loosening assembly 32 is located between the two adjustment assemblies 31. Each adjustment assembly 31 includes a slide rail 311 fixedly connected to the top of the support plate 111, a threaded rod 312 threadedly connected to the slide rail 311, the front side of the threaded rod 312 extending outside the slide rail 311, a slider 313 fixedly connected to the right side of the threaded rod 312, the slider 313 slidably connected to the inner wall of the slide rail 311, a slider 314 slidably connected inside the slide rail 311, a buffer element disposed inside the slide rail 311, and hinge rods 316 hingedly mounted on both the slide rail 311 and the slider 314. Two hinged rods 316 are connected in an inverted V shape, and the two hinged rods 316 are hinged on the side away from the slide rail 311. The loosening component 32 includes a second rotating shaft 321 set on the hinged rods 316, and a loosening roller 322 is fixedly connected to the outer wall of the second rotating shaft 321. The loosening roller 322 is provided with a number of loosening rods, which are distributed in an array. The buffer includes a second spring 315 set in the slide rail 311. The right side of the second spring 315 is fixedly connected to the second slider 314, and the left side of the second spring 315 is fixedly connected to the first slider 313. The second spring 315 is initially in a natural state. By setting the anti-blocking part 3, the flattening and thickness screening of the loosening roller 322 avoids the blockage problem caused by excessively thick straw directly entering the crushing area, thus ensuring the continuous and stable operation of the equipment.

[0029] A specific application of this embodiment is as follows: During use, the height of the rotating shaft 321 and the loosening roller 322 can be adjusted according to the different types of straw. During adjustment, the threaded rod 312 is rotated. As the threaded rod 312 rotates, it slides on the slide rail 311 via the thread on the slide rail 311. During this sliding motion, it pushes the slider 313. At this time, the slider 313 moves along with the slider 314 via the spring 315. Then, the conveying assembly 112 and the motor 218 are started. The straw to be crushed is then placed on the conveying assembly 112. The conveying assembly 112 then transports the straw to the right. As the straw is transported, it interacts with the loosening roller 321. 22 makes contact with the loosening roller 322, flattening the straw and allowing for better crushing. It also blocks thicker straw from entering the fixed box 211 and causing blockages. When encountering very tall straw, the rotating shaft 321 and loosening roller 322 are lifted upwards. During this lifting, the hinge rod 316 changes angle, causing the rotating shaft 321 and loosening roller 322 to move upwards. As they lift, the hinge rod 316 carries the slider 314, which slides within the slide rail 311. The sliding of the slider 314 pulls the spring 315, thus adapting to the movement. Different straw thicknesses and heights prevent straw clogging, thus achieving the effect of loosening the straw. As the straw continues to be transported to the right, it reaches the fixed box 211. At this time, the rotating motor 218 drives the rotating shaft 212 to rotate. During rotation, the roller 213, fixed plate 214, turntable 215, fixed plate 216, spring 217, hinge block 221, crushing blade 222, limit rod 223, and slide rod 224 rotate accordingly. When the crushing blade 222 rotates, it extends on the hinge block 221 through centrifugal force. After use, the motor 218 is stopped, and the centrifugal force... As the pulverizing blade 222 continuously decreases in size, it will swing between the limiting rod 223 and the sliding rod 224 without colliding randomly. After the pulverizing blade 222 stops moving, the sliding rod 224 is pulled in the direction of the pulverizing blade 222. At this time, the sliding rod 224 will slide in the sliding groove 225. With continuous sliding, it will come into contact with the pulverizing blade 222. At this time, the sliding rod 224 and the limiting rod 223 will cooperate to restrict the position of the pulverizing blade 222, so that the pulverizing blade 222 will not swing randomly and cause the blade edges to collide with each other, resulting in blade damage. This can prevent the blade edges from being damaged due to random movement of the pulverizing blade 222 after use.
