Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically an agricultural straw crushing device. Background Technology

[0002] Straw refers to the stalks left after threshing crops and is one of the main by-products of agricultural production. Straw crushing refers to the process of crushing crop residues such as straw using mechanical equipment, such as straw crushers or straw pulverizers. The high-speed rotation of the crushing blades impacts and shears the straw to achieve the purpose of crushing. Finely crushed straw can be used as a feed supplement for ruminants (such as cattle and sheep), especially in winter when forage is scarce. With proper processing, the nutritional value and digestibility of straw can also be improved.

[0003] In existing technologies, straw crushing facilitates the processing of animal feed or the production of organic fertilizer, thus possessing high utilization value. Generally, after collection, straw is added to a straw crusher to crush it into small pieces for later use. However, during the crushing process, some straw remains incompletely crushed, retaining a large volume. In this case, the crushed straw needs to be placed inside a screening machine for screening before being fed back into the crusher. While this effectively crushes the straw, the operation requires workers to move and transport the crushed straw, screen it, and then manually add more straw. This process is not only cumbersome and time-consuming, but also increases the workload when the crusher and screening machine are far apart, and reduces the efficiency of straw crushing. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the cumbersome operation and time-consuming process of screening and secondary feeding of incompletely crushed straw, which can easily reduce the straw crushing efficiency, this utility model proposes an agricultural straw crushing device.

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses an agricultural straw crushing device. (Refer to...) Figure 1 and Figure 3 An agricultural straw crushing device includes a base plate 1, a mounting frame 2 and a fixing frame 7 fixedly connected to the top of the base plate 1, a mounting plate 3 fixedly connected to the inner cavity of the mounting frame 2, a collection box 4 slidably connected to the inner cavity of the mounting plate 3, a straw crusher body 6 fixedly connected to the top of the mounting frame 2, a screening mechanism 5 provided in the inner cavity of the mounting plate 3, a connecting block 8 fixedly connected to the top of the fixing frame 7, a second servo motor 10 fixedly connected to one side of the connecting block 8, the output end of the second servo motor 10 passing through the connecting block 8, and a feeding mechanism 9 provided on one side of the straw crusher body 6.

[0028] The feeding mechanism 9 includes a rotating rod 901, one end of which is rotatably connected to one side of the connecting block 8, and the other end of which is fixedly connected to the output end of the second servo motor 10. A gear 902 is fixedly connected to the surface of the rotating rod 901, and a gear chain 903 is drivenly connected to the surface of the gear 902. A lifting plate 904 is fixedly connected to one end of the gear chain 903. A connecting plate 906 and an electric telescopic rod 908 are fixedly connected to the top of the lifting plate 904. A feeding box 907 is rotatably connected to the top of the connecting plate 906. A slider 910 is slidably connected to the bottom of the feeding box 907. A connecting ring block 909 is fixedly connected to the bottom of the slider 910. One end of the electric telescopic rod 908 is rotatably connected to the surface of the connecting ring block 909. A limit component 905 is provided at one end of the gear chain 903. A fixing rod 911 is fixedly connected to the inner cavity of the fixing frame 7. The inner cavity of the lifting plate 904 is slidably connected to the surface of the fixing rod 911.

[0029] The base plate 1 serves to install and fix the fixing frame 7 and the mounting frame 2. The straw crusher body 6 connected to the top of the mounting frame 2 can crush the straw during operation. The screening mechanism 5 set inside the mounting plate 3 can screen the crushed straw, allowing the uncrushed straw to slide smoothly and be fed again by the feeding mechanism 9. The connecting block 8 can connect to the gear 902 through the rotating rod 901, and drive the gear 902 to rotate when rotating. The rotation of the gear chain 903 can drive the gear chain 903 to transmit power. At the same time, the gear chain 903 will be limited by the limiting component 905 during transmission. The fixed rod 911 can limit the lifting plate 904. This allows the gear chain 903 to lift the lifting plate 904 during transmission, so that the lifting plate 904 drives the connecting plate 906 and the electric telescopic rod 908 to move upward. The second servo motor 10 can drive the rotating rod 901 to rotate during operation, so that the rotation of the rotating rod 901 can be convenient enough.

[0030] Furthermore, the connecting plate 906 can connect to the feeding box 907, and the electric telescopic rod 908 can be connected to the slider 910 through the connecting ring block 909. Since the slider 910 is slidably connected to the feeding box 907, and the connecting ring block 909 is rotatably connected to the electric telescopic rod 908, the electric telescopic rod 908 can lift the feeding box 907 when it extends during operation, so that the feeding box 907 can rotate around the connection point between itself and the connecting plate 906. This allows the feeding box 907 to rotate and tilt. When the feeding box 907 is tilted to a certain angle, it can be used to feed the partially crushed straw after screening, making the feeding of straw convenient and simple. Moreover, when adding straw to the inside of the straw crusher body 6 at the beginning, it can also be operated through the feeding mechanism 9, thereby further reducing the workload of the staff when feeding.

[0031] Reference Figure 3 and Figure 8 The screening mechanism 5 includes a sliding plate 501, the surface of which is slidably connected to the inner cavity of the mounting plate 3. A screening screen block 502 is movably inserted into the top of the sliding plate 501. A first servo motor 503 is fixedly connected to one side of the mounting plate 3. The output end of the first servo motor 503 passes through the mounting plate 3 and is fixedly connected to a cam 504. When the first servo motor 503 is operating, it can drive the cam 504 to rotate. The rotation of the cam 504 can push the sliding plate 501, and after pushing the sliding plate 501, it allows the sliding plate 501 to pass through... The straw falls under its own weight, thus pushing the sliding plate 501 back and forth. The sliding plate 501 drives the screening screen block 502 to move up and down. The screening screen block 502 not only collects the crushed straw, but also screens it during the reciprocating movement. This allows the more completely crushed straw to fall into the inside of the collection box 4. At the same time, the inside of the screening screen block 502 is inclined, so the straw that is not completely crushed can slide into the inside of the feeding box 907, thus achieving subsequent secondary crushing.

[0032] Reference Figure 3 and Figure 6 The limiting component 905 includes a first limiting block 9051, the top of which is fixedly connected to the top of the toothed chain 903. The inner cavity of the fixing frame 7 is provided with a first limiting groove 9052. One side of the first limiting block 9051 is slidably connected to the inner cavity of the first limiting groove 9052. One end of the toothed chain 903 can be used to install and fix the first limiting block 9051, while the first limiting groove 9052 can limit the movement of the first limiting block 9051. Thus, the first limiting block 9051 can play a certain counterweight and limiting role when the toothed chain 903 is driven, so that the transmission of the toothed chain 903 can run stably and smoothly.

[0033] Reference Figure 5 An inclined plate 15 is rotatably connected to one side of the screening mesh block 502, and a support plate 16 is fixedly connected to the bottom of the screening mesh block 502. The inclined plate 15 allows the incompletely crushed straw that slides out of the screening mesh block 502 through the reciprocating movement of the screening mesh block 502 to smoothly slide into the interior of the first limiting inclined block 11. The rotatable connection between the inclined plate 15 and the screening mesh block 502 allows the inclined plate 15 to rotate to one side of the screening mesh block 502 when the feeding box 907 is lifted by the toothed chain 903, thereby reducing the obstruction to the upward movement of the feeding box 907. In normal use, the support plate 16 can provide a certain support for the inclined plate 15, so that the inclined plate 15 is not prone to rotating too far downward due to its own weight, which would prevent it from successfully guiding the sliding straw.

[0034] Reference Figure 7 The bottom of the filling box 907 is provided with a limiting groove 18, and the top of the slider 910 is fixedly connected with a second limiting block 19. The surface of the second limiting block 19 is slidably connected to the inner cavity of the limiting groove 18. The sliding connection between the limiting groove 18 and the second limiting block 19 allows the filling box 907 to limit the limiting groove 18 through the second limiting block 19. This makes the sliding connection between the slider 910 and the filling box 907 more stable when the slider 910 tilts the filling box 907 by the extension of the electric telescopic rod 908.

[0035] Reference Figure 4 The top of the sliding plate 501 is provided with a second limiting groove 17, and the bottom of the screening block 502 is fixedly connected with a sliding rod 14. The surface of the sliding rod 14 is slidably connected to the inner cavity of the second limiting groove 17. The sliding plate 501 can limit the sliding rod 14 through the second limiting groove 17. Due to the connection between the sliding rod 14 and the screening block 502, when the cam 504 rotates and drives the sliding plate 501 and the screening block 502 to vibrate up and down, the screening block 502 is not easy to slip off the top of the sliding plate 501 due to vibration, thereby increasing the stability of the screening block 502 when screening straw.

[0036] Reference Figure 2 and Figure 4The top of the inclined plate 15 is fixedly connected to a second limiting inclined block 13. The inner cavity of the feeding box 907 is fixedly connected to a first limiting inclined block 11 and a triangular block 12. One side of the triangular block 12 is fixedly connected to the surface of the first limiting inclined block 11. The second limiting inclined block 13 can play a certain limiting role in the sliding of incompletely crushed straw, so that it can fall smoothly into the interior of the feeding box 907 and is not likely to scatter a large amount on the ground. The setting of the first limiting inclined block 11 makes it less likely that the feeding box 907 will not be unable to feed straw smoothly when feeding straw because the length of the feeding box 907 itself is greater than the length of the feed inlet of the straw crusher body 6. At the same time, the triangular block 12 can make the straw slide and feed more smoothly when the feeding box 907 adds straw to the interior of the straw crusher body 6 by tilting.

[0037] Working Principle: When using this device, the operator adds the straw to be crushed into the feeding box 907. Then, the second servo motor 10 is activated. During operation, the second servo motor 10 drives the gear 902 to rotate via the rotating rod 901. The rotation of the gear 902 drives the toothed chain 903 for transmission. During transmission, the toothed chain 903, limited by the limiting component 905, smoothly moves the feeding box 907 upwards via the lifting plate 904. Once the feeding box 907 has moved to a certain height, the electric telescopic rod 908 is activated. When the electric telescopic rod 908 extends, it moves the feeding box 907 through the connecting ring block 909 and the slider 910. When the feed box 907 is pushed, it will rotate around the connection point with the connecting plate 906. After rotating to a certain angle, it will add straw into the straw crusher body 6. At this point, the operator can start the straw crusher body 6 to crush the straw. Afterward, the operator can reverse the second servo motor 10 and the electric telescopic rod 908 to move the lifting plate 904 and the feed box 907 down to reset. While moving down, the feed box 907 can be restored to a horizontal state. Before resetting the feed box 907, the operator needs to flip the inclined plate 15 upward to prevent the feed box 907 from being damaged by the inclined plate 15 when moving down. Obstruction prevents smooth downward movement. After the feeding box 907 is reset, the inclined plate 15 is flipped downwards again to ensure normal operation in subsequent use. When the straw crusher body 6 crushes the straw, the crushed straw falls into the screening screen block 502. At this point, the operator can start the first servo motor 503. The operation of the first servo motor 503 drives the cam 504 to rotate, causing the sliding plate 501 and the screening screen block 502 to move up and down reciprocally. As the screening screen block 502 moves up and down, it can collect the straw inside. The straw is screened, causing the more completely crushed straw to fall into the inside of the collection box 4. The straw that is not completely crushed will slide into the inside of the feeding box 907 through the up-and-down reciprocating motion of the screening mesh block 502. When enough straw is collected in the collection box 4, the staff can remove the collection box 4 from the inside of the mounting plate 3 to further process and collect the crushed straw. The staff can repeat the above feeding operation for the straw that is not completely crushed. The second servo motor 10 and the electric telescopic rod 908 are used to feed the straw a second time, so that it can be crushed a second time, thus making the crushing of the straw more complete.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
