DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1-2 As shown, a crop straw crushing device for agricultural use includes a crushing box 1, a groove 11 is opened at the upper end of the crushing box 1 to facilitate the rotation of the arc-shaped round block 23 to avoid it from getting stuck, a feed port 12 is fixedly connected to the upper end of the crushing box 1, an outer shell 13 is fixedly connected to the rear end of the crushing box 1, a discharge port 14 is arranged at the lower end of the crushing box 1, a supporting leg 15 is fixedly connected to the lower end of the crushing box 1, an intermittent feeding component 2 is arranged at the upper end of the crushing box 1, a knocking component 3 is arranged on the right side of the intermittent feeding component 2, a crushing component 4 is arranged inside the crushing box 1, a shaking component 5 is arranged on the lower side of the crushing component 4, a diverter component 6 is arranged on the lower side of the shaking component 5, and a magnetic attraction component 7 is arranged on the lower side of the diverter component 6.

[0036] Therefore, this scheme realizes intermittent feeding and knocking of straw through intermittent feeding component 2 and knocking component 3, so as to prevent problems such as overload and blockage of subsequent crushing work caused by excessive feeding, and also utilizes the cooperation of crushing component 4, shaking component 5, diverter component 6 and magnetic suction component 7 to crush the straw while shaking and bouncing the straw through shaking component 5, so as to screen and crush it again, thereby realizing the simultaneous crushing and screening, avoiding the problem of unstable product quality caused by untimely or inaccurate manual screening, and finally utilizing diverter component 6 and magnetic suction component 7 to divert and separate metal from the screened straw, thereby effectively absorbing the magnetic metal substance in the straw, improving the purity of the straw, improving the continuous operation capacity and production efficiency of the equipment as a whole, and extending the service life of the entire device.

[0037] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of performing knocking and vibration on the feed port 12 while intermittently feeding.

[0038] See also Figure 1-5 The intermittent feeding assembly 2 includes a fixed block 21 fixedly connected to the upper end of the crushing box 1, a motor 22 fixedly connected to the upper end of the crushing box 1, an arc-shaped round block 23 fixedly connected to the output end of the motor 22, an outer surface of the arc-shaped round block 23 is slidably connected to a limiting rod 24, an outer surface of the limiting rod 24 is fixedly connected to a sliding seat 25, and an outer surface of the sliding seat 25 is slidably connected to the fixed block 21.

[0039] See also Figure 3 and Figure 4 A telescopic rod 26 is fixedly connected to the right side of the sliding seat 25, and one end of the telescopic rod 26 away from the sliding seat 25 is fixedly connected to the left end of the lower side of the feed port 12. A spring 27 is fixedly connected to the right side of the sliding seat 25, and the spring 27 is sleeved on the outer surface of the telescopic rod 26. The outer surface of the right side of the sliding seat 25 is slidably connected to the feed port 12.

[0040] Specifically, the connection position between the arc-shaped round block 23 and the motor 1 22 is located on the right side of the arc-shaped round block 23. When the arc-shaped round block 23 rotates, it can continuously drive the limit rod 24 to retreat, and then rebound under the elastic force of the spring 27, driving the sliding seat 25 to move slowly to the left in the feed port 12, and then rebound quickly. The stroke of the arc-shaped round block 23 driving the limit rod 24 to move to the left is equal to the diameter of the lower end of the feed port 12, thereby realizing the intermittent opening and closing of the feed port 12, realizing intermittent feeding, avoiding a large amount of straw rushing in at one time, and causing subsequent crushing overload, blockage and other problems due to excessive feeding. At the same time, the rapid rebound also effectively prevents the straw from being driven to rotate and flip during the crushing process, causing the material to flow back to the feed port 12, and greatly reduces the dust generated in the crushing chamber from flying out of the feed port.

[0041] See also Figure 3 and Figure 5 The knocking assembly 3 includes a connecting block 1 31 fixedly connected to the lower end of the right side of the sliding seat 25, and the front and rear sides of the right end of the connecting block 1 31 are fixedly connected to connecting rods 32. The right ends of the two connecting rods 32 are commonly fixedly connected to a connecting block 2 33, and the right end of the connecting block 2 33 is fixedly connected to a plurality of elastic rollers 331.

[0042] Furthermore, the connecting block 31 will quickly rebound along with the sliding seat 25, and the elastic roller 331 mentioned above generally refers to a roller with certain elastic properties. Structurally, it is generally composed of a roller core, an elastic coating layer and other parts. The roller core is often rigid and plays a supporting role. The material can be metal (such as steel, etc.), providing sufficient strength and structural stability for the entire elastic roller. The elastic coating is the key source of its elasticity. It is usually made of materials with good elasticity and wear resistance such as rubber and polyurethane, and is tightly wrapped around the outside of the roller core. This allows the elastic roller to undergo elastic deformation when subjected to external force such as squeezing, and plays a role in pulling and limiting the rotating plate 36.

[0043] Two fixed seats 34 are fixedly connected to the right side of the upper end of the crushing box 1, and the two fixed seats 34 are rotatably connected to a rotating shaft 1 35 on one side close to each other. A rotating plate 36 is fixedly connected to the outer surface of the rotating shaft 15, and a knocking block 37 is fixedly connected to the left end of the upper side of the rotating plate 36. The outer surface of the knocking block 37 is movably connected to the right side of the feed port 12, and the right end of the connecting block 2 33 is movably connected to the left end of the lower side of the rotating plate 36. The front and rear ends of the lower side of the feed port 12 are fixedly connected to the fixed block 2 38, and the front and rear ends of the inner surface of the lower side of the feed port 12 are provided with sliding grooves 39, and the front and rear ends of the connecting block 1 31 are slidably connected to the two sliding grooves 39.

[0044] Furthermore, the sliding groove 39 is located at the lower side of the sliding seat 25, and the bottom wall of the inner surface of the fixing block 2 38 is inclined toward the inside of the feed port 12, which can not only allow the connecting block 1 31 to slide, but also prevent straw from accumulating in the sliding groove 39 and the fixing block 2 38;

[0045] The rotating plate 36 and the knocking block 37 are pulled by the connecting block 2 33 and the elastic roller 331 to swing. When the connecting block 2 33 pops out quickly following the connecting block 1 31, it will hit the lower end of the rotating plate 36, so that the knocking block 37 at the upper end of the rotating plate 36 hits the outer surface of the feed port 12, which helps to shake off straw debris, dust and other impurities attached to the inner wall of the feed port 12, avoid impurity accumulation that affects the smoothness of feeding, reduce the workload of subsequent cleaning and maintenance, and keep the feed port 12 in a good feeding state at all times.

[0046] Then, straw is poured in from the feed port 12, and the motor 22 is started to drive the arc-shaped round block 23 to rotate. When the arc-shaped round block 23 rotates, the outer surface of the limiting rod 24 is in close contact with the outer surface of the arc-shaped round block 23, so that the arc-shaped round block 23 drives the limiting rod 24 and the sliding seat 25 to move to the left during the rotation process, and the feed port 12 is opened. When the arc-shaped round block 23 rotates to the horizontal plane, that is, when its arc surface is separated from the limiting rod 24, the limiting rod 24 will rebound under the pulling force of the spring 27, so that The limiting rod 24 quickly slides on the horizontal plane of the arc-shaped round block 23 and returns to the initial position, so that the sliding seat 25 blocks the feed port 12. At the same time, when the sliding seat 25 pops out quickly, it drives the connecting block 1 31, the connecting rod 32 and the connecting block 2 33 to quickly collide to the right side, so that the connecting block 2 33 collides with the lower end of the rotating plate 36, so that the knocking block 37 at the upper end of the rotating plate 36 quickly swings to the left side, thereby knocking the feed port 12, causing the feed port 12 to vibrate slightly.

[0047] Therefore, this solution realizes intermittent feeding of straw by cooperating with the intermittent feeding component 2 and the knocking component 3, and utilizes the rotation of the arc-shaped round block 23 to drive the limit rod 24 and the sliding seat 25 to continuously move away or rebound from the feed port 12, thereby avoiding the influx of a large amount of straw at one time, and the subsequent problems such as overload, blockage and backflow of crushing caused by excessive feeding. At the same time, when the sliding seat 25 pops out, it also causes the connecting block 2 33 to push the rotating plate 36 and the knocking block 37 to knock on the feed port 12, thereby shaking off the straw debris, dust and other impurities attached to the inner wall of the feed port 12, avoiding the accumulation of impurities that affect the smoothness of feeding, and reducing the workload of subsequent cleaning and maintenance.

[0048] Embodiment 3: This embodiment is based on Embodiments 1 and 2, and is for achieving the effect of screening the crushed straw and rebounding it for secondary crushing.

[0049] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The crushing assembly 4 includes two crushing mechanisms 41 rotatably connected to the inner surface of the outer shell 13, the crushing mechanism 41 includes a gear 1 411, a gear 2 412, a crushing roller 1 413 and a crushing roller 2 414, the outer surface of the gear 1 411 is meshed with the gear 2 412, the front end of the gear 1 411 is fixedly connected with the crushing roller 1 413, the front end of the gear 2 412 is fixedly connected with the crushing roller 2 414, the diameter ratio of the gear 1 411 to the gear 2 412 is 1.2:1, the diameter ratio of the crushing roller 1 413 to the gear 2 412 is 1.2:1, and the outer surface of the outer shell 13 is fixedly installed with a motor 2 42, and the output end of the motor 2 42 is fixedly connected to the left gear 1 411.

[0050] Specifically, the two crushing mechanisms 41 have the same structure. In the rotation direction, the crushing roller 1 413 and the crushing roller 2 414 are both facing the middle, thereby forming an inward squeezing force and shearing force on both sides, pinching and tearing the straw from both sides, so that the straw is fully cut and crushed in the horizontal direction. Correspondingly, the adjacent crushing roller 2 414 and crushing roller 1 413 at the middle position of the two crushing mechanisms 41 are both rotated outward. This outward rotation mode can make the straw roll and rub between the two rollers after being initially squeezed and crushed inward on both sides, further destroying the internal fiber structure of the straw, changing the angle and position of the straw fragments, and exposing the part that was not fully crushed to the shearing force again, thereby improving the crushing quality and making the crushed straw particles finer and more uniform.

[0051] In terms of rotation speed, since the diameter of gear 2 412 is smaller than that of gear 1 411, gear 2 412 rotates faster, so that the rotation speed of crushing roller 2 414 is faster than that of crushing roller 1 413. The fast-rotating crushing roller 2 414 drives the straw to move quickly, while the slower-rotating crushing roller 1 413 creates obstacles and friction on the straw, so that the straw is subjected to stronger shear force. The friction generated by different rotation speeds can also help remove impurities attached to the surface of the straw, such as some soil, dust, etc. In the process of repeated friction between the fast-rotating and slow-rotating rollers, these impurities are more likely to fall off the surface of the straw, further improving the purity of the crushed straw, which is beneficial to the quality improvement of subsequent products.

[0052] In terms of volume, the diameter of the crushing roller 413 is larger than that of the crushing roller 414. The two crushing rollers 413 can perform preliminary strong crushing on a large amount of larger-sized straws. The two crushing rollers 414 then accurately refine the coarsely crushed materials to achieve progressive crushing from coarse to fine, and can cope with straws of different textures. The hard straw is broken open by the crushing roller 413 to break the hard shell and fiber, and the soft straw is first broken up by the crushing roller 413 to prevent entanglement, and then further crushed by the crushing roller 414, thereby enhancing the adaptability to various crop straws.

[0053] See also Figure 8 and Fig. 9 The shaking component 5 includes a pulley transmission group 51 fixedly connected to the output end of the motor 2 42, and the end of the pulley transmission group 51 away from the output end of the motor 2 42 is fixedly connected to a rotating shaft 511, and the front end of the rotating shaft 511 is rotatably connected to the outer shell 13, and the rear end of the pulley transmission group 51 is fixedly connected to an eccentric shaft 52, and the rear end of the eccentric shaft 52 is rotatably connected to a connecting shaft 1 53, and the lower end of the connecting shaft 1 53 is fixedly connected to a shaking block 1 54, and the middle position of the shaking block 1 54 is fixedly connected to a rotating shaft 3 55, and the outer surface of the rotating shaft 3 55 is fixedly connected to an elastic filter plate 56, and the upper end of the elastic filter plate 56 is provided with a polyurethane elastomer.

[0054] Furthermore, the pulley transmission group 51 is composed of two pulleys and belts of different sizes, and the diameter ratio of the two pulleys is 4:1, wherein the diameter ratio of the pulley fixedly connected to the output end of the motor 2 42 is 1, and the diameter ratio of the pulley fixedly connected to the rotating shaft 511 is 4;

[0055] Furthermore, the polyurethane elastomer mentioned above has high elasticity, high strength and good tear resistance, which can not only bounce up the straw to assist in breaking it up, but also withstand the influence of chemical substances in the fertilizer production process, ensuring the smooth progress of the entire processing process;

[0056] The eccentric shaft 52 is composed of a turntable and a protrusion, and the protrusion is located on one side of the turntable, so that the connecting shaft 53 can follow the rotation of the eccentric shaft 52 to drive the shaking block 54 to swing up and down. Based on the vibration and tilting effect generated by this swing, the screening function of the crushed straw is realized. Smaller straw particles can smoothly pass through the elastic filter plate 56 and fall under the action of vibration and gravity, while larger straw particles cannot pass through the sieve holes of the elastic filter plate 56, and will be continuously bounced up during the swinging process of the elastic filter plate 56, and return to the crushing area for secondary crushing.

[0057] Then, the starting motor 2 42 drives the gear 1 411 and the gear 2 412 in the two crushing mechanisms 41 to mesh, so that the crushing roller 1 413 and the crushing roller 2 414 rotate to crush the straw. At the same time, the motor 2 42 drives the pulley transmission group 51 to rotate synchronously. Through the diameter difference between the large and small pulleys of the pulley transmission group 51, the rotation speed of the rotating shaft 51 is slow, thereby driving the eccentric shaft 52 to drive the connecting shaft 1 53 and the shaking block 1 54 to continuously swing up and down, so that the rotating shaft 3 55 rotates left and right, thereby driving the elastic filter plate 56 to continuously swing left and right, and the crushed straw falling on its surface is screened. Smaller straw particles can smoothly pass through the elastic filter plate 56 and fall down under the action of vibration and gravity, while larger straw cannot pass through the sieve holes of the elastic filter plate 56, and will be continuously bounced up during the swinging process of the elastic filter plate 56, and return to the crushing area for secondary crushing.

[0058] Therefore, this solution further improves the performance of the crushing component 4 from multiple dimensions through the different directions, rotation speeds and coarseness of the crushing component 4, so that the crushing efficiency, quality and adaptability to different straw characteristics of the straw are significantly improved, and the shaking component 5 is used to make the elastic filter plate 56 continuously swing left and right under the drive of the motor 2 42 to screen the straw. The larger straw will be continuously bounced up during the swinging of the elastic filter plate 56 and return to the crushing area for secondary crushing. The screening and secondary crushing are carried out simultaneously without manual intervention, avoiding the problem of unstable product quality due to untimely or inaccurate manual screening, and improving the automation level and production efficiency of the entire crushing device.

[0059] Embodiment 4: Based on Embodiments 1, 2 and 3, this embodiment is to achieve the effect of separating and removing magnetic metal substances in straw.

[0060] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 The diverter assembly 6 includes a connecting shaft 61 rotatably connected to both sides of the rear end of the rocking block 54, the lower ends of the two connecting shafts 61 are rotatably connected to the rocking block 63, the middle position of the rocking block 63 is fixedly connected to the rotating shaft 62, the outer surface of the rotating shaft 62 is fixedly connected to the diverter plate 64, the lower end of the diverter plate 64 is provided with two movable grooves 641, the inner surfaces of the two movable grooves 641 are fixedly connected to the limiting blocks 642, the outer surfaces of the two limiting blocks 642 are rotatably connected to the rotating blocks 643, the outer surfaces of the two rotating blocks 643 are fixedly connected to the annular connecting blocks 65, and the two annular connecting blocks 65 are fixedly connected to the connecting seat 66 on the sides close to each other.

[0061] Specifically, the shaking block 2 63 can swing left and right synchronously with the shaking block 1 54 through the connecting shaft 2 61, thereby realizing the diversion of the straw, allowing the crushed straw to slide down from the electromagnetic plates 72 on both sides, ensuring that the straw is more evenly distributed on the electromagnetic plates 72 during the subsequent processing process.

[0062] See also Fig.10 and Fig.11 A through slot 612 is provided at the bottom end of the crushing box 1, a support rod 611 is fixedly connected to the inner surface of the through slot 612, a base 610 is fixedly connected to the middle position of the support rod 611, a rotating rod 68 is rotatably connected to the upper end of the base 610, a plurality of breaking blades 69 are fixedly connected to the outer surface of the rotating rod 68, a rotating disk 67 is fixedly connected to the upper end of the rotating rod 68, and one side of the upper end of the rotating disk 67 is fixedly connected to the lower end of the connecting seat 66.

[0063] Furthermore, when the diverter plate 64 swings left and right, it will drive the annular connecting block 65 and the connecting seat 66 at the lower end to continuously swing and rotate with the rotating disk 67 as the axis, so that the rotating rod 68 rotates continuously, allowing the breaking blades 69 to continue to break up the material during the falling process, so that the straw can contact the electromagnetic plate 72 more fully, increasing the contact area and contact opportunity between the straw and the electromagnetic plate 72, and further improving the metal adsorption effect. At the same time, the straw after breaking up is in a looser state, which is also helpful for subsequent storage, transportation and other processing and utilization.

[0064] See also Figure 2 The magnetic attraction assembly 7 includes a second connection seat 71 fixedly connected to both sides of the bottom wall of the inner surface of the crushing box 1, and an electromagnetic plate 72 is fixedly installed on the outer surface of the two second connection seats 71.

[0065] Furthermore, the side of the electromagnetic plate 72 that contacts the straw is an inclined surface, which can extend the time the straw stays on its surface. When the crushed straw contacts the electromagnetic plates 72 on both sides, the electromagnetic plates 72 can effectively absorb the mixed magnetic metal substances therein, such as iron nails, iron wires, etc., to prevent metal impurities from mixing into subsequent processed products, causing damage to processing equipment, and affecting product quality.

[0066] Furthermore, when the shaking block 54 rotates, the two connecting shafts 61 will drive the shaking block 63 and the shaking block 54 to swing synchronously, so that the rotating shaft 4 62 rotates back and forth, further driving the internal diverter plate 64 to tilt left and right, diverting the screened straw and making it slide down along the surface of the electromagnetic plates 72 on both sides. At the same time, when the diverter plate 64 swings left and right, because the bottom connecting seat 66 and one side of the rotating disk 67 are fixed and limited, the swing of the diverter plate 64 will drive the annular connecting block 65 and the connecting seat 66 to rotate as a whole with the rotating disk 67 as the axis, so that the rotating rod 68 and the scattering blades 69 rotate, and the scattering blades 69 will continuously scatter the fallen straw, so that the straw can contact with the electromagnetic plate 72 more fully, thereby increasing the contact area and contact opportunity between the straw and the electromagnetic plate 72, and further improving the metal adsorption effect.

[0067] Therefore, this solution makes the diverter plate 64 and the elastic filter plate 56 move synchronously through the cooperation of the shaking component 5, the diverter component 6 and the magnetic suction component 7, and diverts the screened straw to make it slide on the surface of the electromagnetic plate 72, and uses the breaking blades 69 to continuously break up the straw so that the straw can contact the electromagnetic plate 72 more fully, thereby increasing the contact area and contact opportunity between the straw and the electromagnetic plate 72, further improving the metal adsorption effect, and at the same time, the straw after breaking up is in a looser state, avoiding the occurrence of problems such as agglomeration, and also facilitating subsequent storage, transportation and other processing and utilization.
