Description

Technical Field

[0001] The present invention relates to the technical field of straw crushers, and more specifically, to an agricultural crusher for facilitating the treatment of bundled straw. Background Art

[0002] An agricultural straw crusher is an agricultural machinery and equipment specifically used for crushing and treating crop straw. As a common waste in agricultural production, if crop straw is directly burned or stacked, it will cause significant pollution to the environment. Therefore, through crushing treatment, converting straw into organic fertilizer or biomass energy and realizing the reuse of resources is of great significance for reducing environmental pollution. With the continuous improvement of agricultural mechanization and the increasing awareness of environmental protection, farmers' demand for efficient and environmentally friendly straw treatment equipment is becoming increasingly urgent. Against this background, the agricultural straw crusher stands out with its high efficiency. This equipment can quickly and effectively process straw into fine particles, providing convenient conditions for subsequent resource utilization.

[0003] Chinese Patent Publication No. CN219536890U discloses an agricultural straw crusher, including a crusher housing, a transmission shaft, a sieve plate, and a transmission plate; by arranging a dial rod that rotates synchronously with the outer wall of the transmission shaft, and rotatably installing a percussion plate on the outer wall of the crusher housing through a torsion spring, and arranging a percussion shaft for percussing the transmission plate on the outer wall of the percussion plate, the sieve plate is driven to vibrate through the transmission plate, which is used to prevent materials from accumulating above the sieve plate, effectively improving the discharging efficiency. At the same time, compared with the existing method of manually cleaning the materials accumulated on the sieve plate, it can achieve cleaning without stopping the machine, improving the use safety and further increasing the discharging rate.

[0015] The present invention also provides a tomato fertilization method, which is applied to the above-mentioned agricultural crusher for facilitating the treatment of bundled straws, and is characterized by including the following steps;

[0016] S1. First, put the bundled straws into the feed inlet at the top of the crusher housing, start the rotation driving component to drive the two crushing rollers to rotate relatively, and cut the straws. And start the linear driver, and the linear driver is a pushing cylinder. The working end of the linear driver drives the pressing block to move downwards. As the pressing block moves downwards, the pressing block gradually approaches and contacts the material, applying a certain pressure to the material. The applied pressure can assist the straws to be more easily broken by the crushing rollers, and prevent the straws from being blocked during the feeding process, affecting the crushing efficiency.

[0017] S2. The crushed straw particles fall onto the sieve mesh. The sieve mesh screens the particle size of the straw to ensure that the output straw particles have uniform particle size. To prevent the straw from accumulating on the sieve mesh, the second motor is started. The output end of the second motor drives the first gear to rotate, and then drives the second gear meshing with the first gear to rotate. With the rotation of the second gear, the fixed column and the driving plate will perform circular motion. Since one end of the connecting plate is hinged to one end of the driving plate, the circular motion of the driving plate will drive the connecting plate to slide reciprocally within the sliding seat, and the movement of the connecting plate will further drive the hinge seat and the telescopic plate to perform telescopic motion. One end of the telescopic plate is connected to the sieve mesh, so the telescopic motion of the telescopic plate will push one end of the sieve mesh to move reciprocally, thereby being able to continuously change the accumulation state of the straw particles on the sieve mesh, prevent the straw particles from forming a fixed accumulation area. At the same time, the movement of the sieve mesh can also promote the relative movement between the straw particles and improve the screening efficiency.

[0018] S3. During the screening process, if the sieve mesh becomes blocked, the feeding is stopped and the first motor is started. The output end of the first motor drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the moving plate, the moving plate will move along the direction of the threaded rod. The movement of the moving plate drives the connecting block and the inclined plate to move together, and the movement of the inclined plate drives the cleaning column to clean the sieve holes of the sieve mesh, thereby preventing the sieve mesh from being blocked.

[0019] The beneficial effects of the present invention compared with the prior art are:

[0020] 1. In the present invention, by starting the first motor, the output end of the first motor drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the moving plate, the moving plate will move along the direction of the threaded rod. The movement of the moving plate drives the connecting block and the inclined plate to move together, and the movement of the inclined plate drives the cleaning column to clean the sieve holes of the sieve mesh, thereby preventing the sieve mesh from being blocked.

[0021] 2. In the present invention, by starting the second motor to drive the first gear to rotate, and then driving the second gear meshing with the first gear to rotate. The fixed column and the driving plate will perform circular motion. Since one end of the connecting plate is hinged to one end of the driving plate, the circular motion of the driving plate will drive the connecting plate to slide reciprocally within the sliding seat, and the movement of the connecting plate will further drive the hinge seat and the telescopic plate to perform telescopic motion. Therefore, the telescopic motion of the telescopic plate will push one end of the sieve mesh to move reciprocally, thereby being able to continuously change the accumulation state of the straw particles on the sieve mesh, prevent the straw particles from forming a fixed accumulation area. At the same time, the movement of the sieve mesh can also promote the relative movement between the straw particles and improve the screening efficiency.

[0022] 3. The present invention starts the linear driver, which is a pushing cylinder. The working end of the linear driver drives the pressing block to move downward. As the pressing block moves downward, it gradually approaches and contacts the material, applying a certain pressure to the material. The applied pressure can assist the straw to be more easily crushed by the crushing roller, preventing the straw from jamming during the feeding process and affecting the crushing efficiency.

Detailed implementation manners

[0034] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0035] See Figures 1 to 10 As shown, a farm crusher and a crushing method for facilitating the treatment of bundled straws include a crusher housing 1. A feed inlet 2 is arranged at the top of the crusher housing 1. Two relatively rotatable crushing rollers 3 are arranged in the crusher housing 1. A rotation driving component for driving the two crushing rollers 3 to rotate relatively is also arranged on the crusher housing 1. A screen 4 is also arranged in the crusher housing 1. An anti-accumulation component 5 for preventing the straws from accumulating is arranged at one end of the screen 4. A discharge port is formed on one side of the crusher housing 1. A waste bin 6 is arranged on one side of the discharge port. A collection box 7 is slidably arranged at the bottom of the screen 4 in the crusher housing 1. An anti-blocking component 8 is also arranged at the top of the screen 4. The anti-blocking component 8 includes an inclined plate 81 that can move along the inner wall of the crusher housing 1, a cleaning column 83 arranged at the bottom of the inclined plate 81 for cleaning the screen holes of the screen 4, and a threaded driving component for driving the inclined plate 81 to move. A pressing-down component 9 for preventing the straws from blocking is also arranged at the top of the feed inlet 2.

[0036] The bundled straw is fed into the feed inlet 2 at the top of the crusher housing 1. By starting the rotation drive component, two groups of crushing rollers 3 are driven to rotate relative to each other to cut the straw. And a pressing component 9 is arranged at the top of the feed inlet 2, so that the straw can smoothly enter between the two groups of crushing rollers 3, preventing the straw from being blocked during the feeding process. The crushed straw particles fall on the screen 4. The particle size of the straw is screened by the screen 4 to ensure that the particle size of the output straw particles is uniform. To prevent the straw from accumulating on the screen 4, an anti-accumulation component 5 is arranged at one end of the screen 4, and the anti-accumulation component 5 prevents the straw from accumulating on the screen 4, ensuring the continuity and efficiency of the screening process. During the screening process, if the screen 4 is blocked, the anti-blocking component 8 starts to work. The inclined plate 81 moves along the inner wall of the crusher housing 1 under the drive of the threaded drive component, and the cleaning column 83 arranged at the bottom of the inclined plate 81 cleans the screen holes of the screen 4 as the inclined plate 81 moves, thereby preventing the screen 4 from being blocked. The straw particles after screening fall from the screen 4 into the collection box 7, which is convenient for collection and subsequent processing. The larger fragments or other impurities that cannot pass through the screen 4 fall into the waste box 6 through the discharge port, which is convenient for the user to clean and process later.

[0037] See Figures 5 to 6 As shown, the anti-blocking component 8 further includes a guide block 82; a rectangular through groove for the crushed straw to move is formed on the inclined plate 81, the guide block 82 is arranged on the inner wall of the crusher housing 1, the inclined end of the guide block 82 points to the rectangular through groove, and the inclined end of the guide block 82 abuts against the top of the inclined plate 81.

[0038] When the bundled straw is crushed by the crushing rollers 3, the crushed straw particles will fall on the inclined plate 81. At this time, the inclined design of the guide block 82 will guide the straw particles to smoothly enter the rectangular through groove along the inclined surface of the guide block 82. Under the combined action of the guide block 82 and the inclined plate 81, the crushed straw can continuously and smoothly enter the screen 4 for screening.

[0039] See Figures 5 to 6 As shown, the threaded drive component includes a connecting block 84 and a mounting frame 85; the connecting block 84 is arranged at the top of the inclined plate 81; the mounting frame 85 is arranged on one side of the crusher housing 1, a threaded rod 86 is arranged in the mounting frame 85, a first motor 87 is arranged at the top of the mounting frame 85, the output end of the first motor 87 is connected to the threaded rod 86, and a moving plate 88 is threadedly connected to the threaded rod 86, and one end of the moving plate 88 is connected to one side of the connecting block 84.

[0040] When it is necessary to clean the sieve holes of the sieve 4, the first motor 87 is started, and the output end of the first motor 87 drives the threaded rod 86 to rotate. Since the threaded rod 86 is threadedly connected to the moving plate 88, the moving plate 88 will move along the direction of the threaded rod 86. The movement of the moving plate 88 drives the connecting block 84 and the inclined plate 81 to move together, and the movement of the inclined plate 81 drives the cleaning column 83 to clean the sieve holes of the sieve 4.

[0041] See Figure 5 As shown, on both sides of the threaded rod 86 on the mounting frame 85, there are smooth rods 89, and through holes for the smooth rods 89 to move are opened on the moving plate 88.

[0042] When the rotation of the threaded rod 86 drives the moving plate 88 to move, the moving plate 88 will slide on the smooth rod 89 through the through hole on the moving plate 88, thereby improving the stability of the movement of the moving plate 88.

[0043] See Figure 5 and Figure 6 As shown, a limit slider is provided on one side of the inclined plate 81, and a limit chute for the limit slider to move is opened on the inner wall of the crusher housing 1.

[0044] When the movement of the moving plate 88 drives the connecting block 84 and the inclined plate 81 to move together, the inclined plate 81 will move in the limit chute through the limit slider on one side, thereby ensuring the stability and accuracy of the inclined plate 81 during the movement.

[0045] See Figures 7 to 8 As shown, the anti - accumulation component 5 includes a first extension frame 51 and a sliding seat 57; one end of the sieve 4 is rotatably arranged in the crusher housing 1, the first extension frame 51 is arranged on one side of the crusher housing 1, a second motor 52 is arranged on one side of the first extension frame 51, the output end of the second motor 52 is provided with a first gear 53, a second gear 54 is arranged on one side of the first gear 53 through a rotating shaft, the second gear 54 meshes with the first gear 53, a fixed column 55 is arranged on one side of the second gear 54, and a driving plate 56 is arranged on the fixed column 55; the sliding seat 57 is arranged on one side of the crusher housing 1, a connecting plate 58 is slidably arranged in the sliding seat 57, one end of the connecting plate 58 is hinged to one end of the driving plate 56, a hinge seat 59 is arranged on one side of the connecting plate 58, a telescopic plate 510 is hinged in the hinge seat 59, and one end of the telescopic plate 510 is connected to one end of the sieve 4.

[0046] To prevent the accumulation of straw particles on the screen 4, the second motor 52 is started. The output end of the second motor 52 drives the first gear 53 to rotate, which in turn drives the second gear 54 meshing with the first gear 53 to rotate. As the second gear 54 rotates, the fixed column 55 and the driving plate 56 will perform circular motion. Since one end of the connecting plate 58 is hinged to one end of the driving plate 56, the circular motion of the driving plate 56 will drive the connecting plate 58 to reciprocate within the sliding seat 57, and the movement of the connecting plate 58 will further drive the hinge seat 59 and the telescopic plate 510 to perform telescopic motion. One end of the telescopic plate 510 is connected to the screen 4, so the telescopic motion of the telescopic plate 510 will push one end of the screen 4 to reciprocate, thereby continuously changing the accumulation state of the straw particles on the screen 4, preventing the straw particles from forming a fixed accumulation area. At the same time, the movement of the screen 4 can also promote the relative movement between the straw particles and improve the screening efficiency.

[0047] See Figure 10 As shown, the pressing assembly 9 includes a rectangular frame 91; the rectangular frame 91 is arranged at the top of the crusher housing 1, and a linear actuator 92 is arranged at the top of the rectangular frame 91, and a pressing block 93 is arranged at the working end of the linear actuator 92.

[0048] When it is necessary to press down the material, the linear actuator 92 is started. The linear actuator 92 is a pushing cylinder. The working end of the linear actuator 92 drives the pressing block 93 to move downward. As the pressing block 93 moves downward, the pressing block 93 gradually approaches and contacts the material, applying a certain pressure to the material. The applied pressure can assist the straw to be more easily broken by the crushing roller 3 and prevent the straw from being blocked during the feeding process, affecting the crushing efficiency.

[0049] See Figure 10 As shown, guide rods 94 are slidably arranged on both sides of the linear actuator 92 at the top of the rectangular frame 91. One end of the guide rod 94 is connected to the top of the pressing block 93, and a limit disk 95 is arranged at the other end of the guide rod 94.

[0050] When the working end of the linear actuator 92 drives the pressing block 93 to move downward, the guide rod 94 also slides synchronously in the top of the rectangular frame 91. The design of the guide rod 94 ensures the stability and accuracy of the pressing block 93 during the movement process, preventing the pressing block 93 from shifting or shaking due to uneven force.

[0051] See Figure 9As shown in the figure, the rotation driving component includes a third gear 31 and a second extension frame 32; one end of two groups of crushing rollers 3 extends outwards through one side of the crusher housing 1, the third gear 31 is arranged at the extension ends of the two groups of crushing rollers 3, and the two groups of third gears 31 are meshed with each other; a second extension frame 32 is arranged on one side of the crusher housing 1, a third motor 33 is arranged on one side of the second extension frame 32, and the output end of the third motor 33 is connected to the extension end of one side of the crushing roller 3.

[0052] Start the third motor 33, the output end of the third motor 33 starts to rotate, and drives the connected crushing roller 3 to rotate synchronously. Since the two groups of third gears 31 are meshed with each other, when one crushing roller 3 rotates, it will drive the other crushing roller 3 to rotate synchronously through the meshing action of the two groups of third gears 31, so as to drive the two groups of crushing rollers 3 to rotate relatively and cut the straw.

[0053] The bundled straw is fed into the feed inlet 2 at the top of the crusher housing 1. By starting the rotational drive component, the two groups of crushing rollers 3 are driven to rotate relative to each other to chop the straw. And by starting the linear drive 92, the linear drive 92 is a pushing cylinder. The working end of the linear drive 92 drives the pressing block 93 to move downward. As the pressing block 93 moves downward, the pressing block 93 gradually approaches and contacts the material, applying a certain pressure to the material. The applied pressure can assist the straw to be more easily crushed by the crushing rollers 3, preventing the straw from clogging during the feeding process and affecting the crushing efficiency. The crushed straw particles fall on the screen 4. The screen 4 is used to screen the particle size of the straw to ensure that the output straw particles have a uniform particle size. To prevent the straw from accumulating on the screen 4, the second motor 52 is started. The output end of the second motor 52 drives the first gear 53 to rotate, and then drives the second gear 54 meshing with the first gear 53 to rotate. As the second gear 54 rotates, the fixed column 55 and the drive plate 56 will perform circular motion. Since one end of the connecting plate 58 is hinged to one end of the drive plate 56, the circular motion of the drive plate 56 will drive the connecting plate 58 to reciprocate in the sliding seat 57. The movement of the connecting plate 58 will further drive the hinge seat 59 and the telescopic plate 510 to perform telescopic motion. One end of the telescopic plate 510 is connected to the screen 4, so the telescopic motion of the telescopic plate 510 will push one end of the screen 4 to reciprocate, so as to continuously change the accumulation state of the straw particles on the screen 4, prevent the straw particles from forming a fixed accumulation area. At the same time, the movement of the screen 4 can also promote the relative movement between the straw particles and improve the screening efficiency. During the screening process, if the screen 4 is clogged, the feeding is stopped, and the first motor 87 is started. The output end of the first motor 87 drives the threaded rod 86 to rotate. Since the threaded rod 86 is threadedly connected to the moving plate 88, the moving plate 88 will move along the direction of the threaded rod 86. The movement of the moving plate 88 drives the connecting block 84 and the inclined plate 81 to move together. The movement of the inclined plate 81 drives the cleaning column 83 to clean the screen holes of the screen 4, so as to prevent the screen 4 from being clogged. The straw particles after screening fall from the screen 4 into the collection box 7 for easy collection and subsequent processing. The larger fragments or other impurities that cannot pass through the screen 4 fall into the waste box 6 through the discharge port for easy subsequent cleaning and processing by the user.

[0054] The present invention also provides a tomato fertilization method, which is applied to the above-mentioned agricultural crusher for facilitating the treatment of bundled straw, and is characterized in that it includes the following steps;

[0055] S1. First, put the bundled straw into the feed inlet 2 at the top of the crusher housing 1, start the rotary drive component to drive the two groups of crushing rollers 3 to rotate relative to each other, and chop the straw. Then start the linear drive 92, and the linear drive 92 is a pushing cylinder. The working end of the linear drive 92 drives the pressing block 93 to move downward. As the pressing block 93 moves downward, the pressing block 93 gradually approaches and contacts the material, applying a certain pressure to the material. The applied pressure can assist the straw to be more easily crushed by the crushing rollers 3 and prevent the straw from being blocked during the feeding process, affecting the crushing efficiency.

[0056] S2. The crushed straw particles fall on the screen 4. The screen 4 is used to screen the particle size of the straw to ensure that the output straw particles have uniform particle size. To prevent the straw from accumulating on the screen 4, start the second motor 52. The output end of the second motor 52 drives the first gear 53 to rotate, and then drives the second gear 54 meshing with the first gear 53 to rotate. As the second gear 54 rotates, the fixed column 55 and the drive plate 56 will perform circular motion. Since one end of the connecting plate 58 is hinged to one end of the drive plate 56, the circular motion of the drive plate 56 will drive the connecting plate 58 to slide reciprocally in the sliding seat 57. The movement of the connecting plate 58 will further drive the hinge seat 59 and the telescopic plate 510 to perform telescopic motion. One end of the telescopic plate 510 is connected to the screen 4, so the telescopic motion of the telescopic plate 510 will push one end of the screen 4 to move reciprocally, so as to continuously change the accumulation state of the straw particles on the screen 4, prevent the straw particles from forming a fixed accumulation area. At the same time, the movement of the screen 4 can also promote the relative movement between the straw particles and improve the screening efficiency.

[0057] S3. During the screening process, if the screen 4 is blocked, stop feeding and start the first motor 87. The output end of the first motor 87 drives the threaded rod 86 to rotate. Since the threaded rod is threadedly connected to the moving plate 88, the moving plate 88 will move along the direction of the threaded rod 86. The movement of the moving plate 88 drives the connecting block 84 and the inclined plate 81 to move together, and the movement of the inclined plate 81 drives the cleaning column 83 to clean the screen holes of the screen 4, so as to prevent the screen 4 from being blocked.

[0058] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

10. A method for crushing bales of straw, applied to an agricultural crusher for processing bales of straw as claimed in any one of claims 1 to 9, characterized in that: The steps include: S1. First, feed the bundled straw from the feed port (2) at the top of the pulverizer housing (1), and start the rotating drive component to drive the two sets of crushing rollers (3) to rotate relative to each other to cut the straw. Then start the linear drive (92), which is a push cylinder. The working end of the linear drive (92) drives the pressing block (93) to move downward. As the pressing block (93) moves downward, the pressing block (93) gradually approaches and contacts the material, exerting a certain pressure on the material. The applied pressure can help the straw to be more easily crushed by the crushing rollers (3), thereby preventing the straw from being blocked during the feeding process and affecting the crushing efficiency. S2. The crushed straw particles fall onto the screen (4). The particle size of the straw is screened by the screen (4) to ensure that the output straw particles have a uniform particle size. To prevent the straw from piling up on the screen (4), the second motor (52) is started. The output end of the second motor (52) drives the first gear (53) to rotate, thereby driving the second gear (54) meshed with the first gear (53) to rotate. As the second gear (54) rotates, the fixed column (55) and the drive plate (56) perform circular motion. Since one end of the connecting plate (58) is hinged to one end of the driving plate (56), the circular motion of the driving plate (56) drives the connecting plate (58) to slide back and forth in the sliding seat (57), and the movement of the connecting plate (58) further drives the hinge seat (59) and the telescopic plate (510) to perform telescopic motion. One end of the telescopic plate (510) is connected to the screen (4), so that the telescopic movement of the telescopic plate (510) pushes one end of the screen (4) to move back and forth, thereby continuously changing the accumulation state of the straw particles on the screen (4), preventing the straw particles from forming a fixed accumulation area; at the same time, the movement of the screen (4) can also promote the relative movement between the straw particles, thereby improving the screening efficiency; S3. During the screening process, if the screen (4) is clogged, the feeding is stopped and the first motor (87) is started. The output end of the first motor (87) drives the threaded rod (86) to rotate. Since the threaded rod (86) is threadedly connected to the moving plate (88), the moving plate (88) moves along the direction of the threaded rod (86). The movement of the moving plate (88) drives the connecting block (84) and the inclined plate (81) to move together. The movement of the inclined plate (81) drives the cleaning column (83) to clean the sieve holes of the screen (4), thereby preventing the screen (4) from being clogged.
