Description

Technical Field

[0001] This utility model relates to the technical field of straw crushers, and in particular to a straw crusher for agricultural production. Background Technology

[0002] Straw is the remaining plant material after crop harvesting, typically including corn stalks, wheat straw, etc. Because straw contains a lot of fiber and is difficult to degrade naturally, it can be converted into organic fertilizer, feed, or other usable resources through crushing. Straw crushers are used to mechanically cut and crush straw into smaller particles or fragments, facilitating subsequent processing and utilization.

[0003] Traditional straw crushers typically consist of a feeding system, a crushing device, a transmission system, and a discharge system. The feeding system feeds the straw into the crushing device, which crushes it using rotating blades or hammers. The transmission system drives the crushing device via a power source, while the discharge system removes the crushed straw particles, completing the entire crushing process.

[0004] Traditional straw crushers cannot adjust the size of the crushed material, primarily due to the fixed design of their crushing devices. These devices typically rely on high-speed rotating blades or hammers, which are designed with specific gaps and movement patterns, thus preventing flexible adjustment of particle size. The lack of an adjustment mechanism results in uniform particle size, failing to adapt to different application needs and impacting subsequent straw processing, such as the fermentation rate of organic fertilizer or the digestibility of feed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a straw crusher for agricultural production, aiming to improve the problem that traditional straw crushers cannot adjust the crushing size and cannot be adapted to different application needs, thus affecting the subsequent processing effect of straw, such as the fermentation rate of organic fertilizer or the digestibility of feed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a straw crusher for agricultural production, including a crushing chamber, a side platform fixedly connected to the side wall of the crushing chamber, a plurality of motors II being provided on the side wall of the side platform, a crushing roller being fixedly connected to the output end of each motor II, a motor I being fixedly connected to the top of the side platform, a gear I being fixedly connected to the output end of the motor I, and an adjustment component being provided on the upper surface of the side platform.

[0007] The adjustment assembly includes multiple fixed columns, the bottom of which are fixedly connected to the upper surface of the motor. Each fixed column has a sliding table slidably connected inside, and each sliding table has a rack fixedly connected to its side wall. The rack meshes with the gear. The side walls of the multiple motors are respectively fixedly connected to the side walls of the racks. A discharge assembly is provided at the bottom of the crushing chamber.

[0008] Furthermore, the discharge assembly includes a discharge platform, the sidewall of which is fixedly connected to the sidewall of the crushing chamber.

[0009] Furthermore, a sealing cover is provided inside the discharge platform, and a turntable is fixedly connected to both the sealing cover and the side wall of the discharge platform.

[0010] Furthermore, rotating rods are rotatably connected between the multiple turntables, and a fixing member is fixedly connected to the side wall of the sealing cover.

[0011] Furthermore, a second gear is fixedly connected to the side wall of the fixing component, and a connecting platform is fixedly connected to the upper surface of the discharge platform.

[0012] Furthermore, an electric push rod is fixedly connected to the upper surface of the discharge platform, and a toothed plate is fixedly connected to the output end of the electric push rod.

[0013] Furthermore, the toothed plate is slidably connected inside the connecting platform, and the toothed plate meshes with the gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, motor one drives gear one to rotate, which in turn pushes multiple racks. After the racks are subjected to force, they drive the slide table to slide inside the fixed column. This sliding process can drive motor two to move synchronously. The change in the position of motor two can adjust the distance of multiple crushing rollers, so as to realize the flexible adjustment of the size of straw crushing. It can be adapted to different application needs to improve digestibility and absorption effect.

[0016] 2. In this utility model, the toothed plate slides horizontally inside the connecting platform. This sliding process will push the second gear, causing the second gear to drive the fixed part to rotate, which in turn drives the sealing cover to be subjected to force, so that the rotating rod rotates between multiple rotating platforms. The flipping of the sealing cover relative to the discharge platform can realize the opening and closing of the discharge platform, which can quickly and smoothly discharge the crushed straw and avoid accumulation and blockage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a straw crusher for agricultural production, comprising a crushing chamber 1, a side platform 2 fixedly connected to the side wall of the crushing chamber 1, and multiple motors 8 mounted on the side wall of the side platform 2. Each motor 8 has a crushing roller 9 fixedly connected to its output end. The crushing roller 9 is used for preliminary crushing of the straw, ensuring that the straw reaches the required degree of crushing before entering the discharge channel. A motor 3 is fixedly connected to the top of the side platform 2, and a gear 4 is fixedly connected to the output end of the motor 3. The motor 3 provides power support, and the gear 4 transmits power and drives the subsequent adjustment components. An adjustment component is provided on the upper surface of the side platform 2. The adjustment component adjusts the distance between the crushing rollers 9, thereby controlling the particle size of the crushed straw. The adjustment component includes multiple fixed columns 5, the bottom of which are fixedly connected to the motors 8. On the upper surface of the 3rd column, each fixed column 5 has a sliding table 6 inside. The function of the sliding table 6 is to change the relative position of the crushing roller 9 by sliding, thereby adjusting the crushing effect of the straw. Each sliding table 6 has a rack 7 fixedly connected to its side wall. The rack 7 meshes with the gear 4. By sliding the rack 7 and rotating the gear 4, the movement of the sliding table 6 can be precisely controlled, thereby precisely adjusting the distance of the crushing roller 9. Multiple motors 8 are fixedly connected to the side walls of multiple racks 7. The connection between the motors 8 and the racks 7 ensures the power supply to the crushing roller 9, ensuring the effective crushing of straw. The bottom of the crushing chamber 1 is equipped with a discharge component. The design of the discharge component ensures that the crushed straw can be discharged smoothly, avoiding the accumulation of material in the chamber, which would affect the continuous working efficiency of the machine, and enabling the straw to be processed in a timely and effective manner.

[0025] Specifically, when adjusting the size of the crushed straw, motor 3 is started. Motor 3 drives gear 4 to rotate, and gear 4 further pushes multiple racks 7. After being stressed, the racks 7 drive the slide table 6 to slide inside the fixed column 5. The sliding of the slide table 6 causes motor 8 to move synchronously. The change in the position of motor 8 adjusts the distance between multiple crushing rollers 9. By changing the distance between the crushing rollers 9, the size of the crushed straw can be flexibly adjusted to adapt to different application needs. For example, finer particles help improve the digestibility of feed or accelerate the fermentation process of organic fertilizer, ensuring that the crushing effect matches the requirements of subsequent processing, and ultimately improving the utilization efficiency and quality of straw.

[0026] Reference Figure 4The discharge assembly includes a discharge platform 10, the side wall of which is fixedly connected to the side wall of the crushing chamber 1. A sealing cover 11 is provided inside the discharge platform 10. A turntable 15 is fixedly connected to both the sealing cover 11 and the side wall of the discharge platform 10. A gear 18 is fixedly connected to the side wall of the fixing component 17. A connecting platform 14 is fixedly connected to the upper surface of the discharge platform 10. An electric push rod 12 is fixedly connected to the upper surface of the discharge platform 10. A toothed plate 13 is fixedly connected to the output end of the electric push rod 12. The toothed plate 13 is slidably connected inside the connecting platform 14 and meshes with the gear 18.

[0027] Specifically, when it is necessary to discharge the crushed straw, the electric push rod 12 is activated to push the toothed plate 13. The toothed plate 13 slides horizontally inside the connecting platform 14. This sliding process drives the gear 18, which in turn drives the fixing part 17 to rotate, thereby causing the sealing cover 11 to be subjected to force. This causes the rotating rod 16 to rotate between multiple rotating platforms 15. The flipping of the sealing cover 11 relative to the discharge platform 10 realizes the opening and closing of the discharge platform 10. Through this process, the crushed straw can be discharged quickly and smoothly, avoiding accumulation and blockage, ensuring that the equipment can operate continuously and stably, improving work efficiency and reducing the need for equipment maintenance.

[0028] Working principle: When adjusting the size of the crushed straw, motor 3 is started. Motor 3 drives gear 4 to rotate, which in turn pushes multiple racks 7. After being stressed, the racks 7 drive the slide table 6 to slide inside the fixed column 5. This sliding process drives motor 8 to move synchronously. Changing the position of motor 8 adjusts the distance between multiple crushing rollers 9, realizing flexible adjustment of the size of the crushed straw. It can be adapted to different application needs to improve digestibility and absorption. When it is necessary to discharge the crushed straw, the electric push rod 12 is started to push the toothed plate 13, which slides horizontally inside the connecting platform 14. This sliding process pushes gear 18, which drives the fixed part 17 to rotate, which in turn drives the sealing cover 11 to be stressed. This causes the rotating rod 16 to rotate between multiple rotating platforms 15. The flipping of the sealing cover 11 relative to the discharge platform 10 realizes the opening and closing of the discharge platform 10, which can quickly and smoothly discharge the crushed straw and avoid accumulation and blockage.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
