Description

Technical Field

[0001] This utility model relates to the technical field of crushing mechanisms for silage harvesters, and in particular to a grain crusher for silage harvesters. Background Technology

[0002] A silage harvester is an agricultural machine mainly used for harvesting silage. It is primarily used for cutting and conveying corn stalks and seeds. During the cutting process, the whole corn stalk is first crushed by the cutter of the coarse crushing roller. After coarse crushing, it is conveyed between two fine crushing rollers. The rotation of the fine crushing rollers achieves fine crushing. After fine crushing, it is discharged from the discharge port. Both the coarse and fine crushing rollers are seed crushers of the silage harvester.

[0003] In the grain crusher of a silage harvester, the fine crushing roller is fixed to the end seat by bolts. The end seat is installed inside the silage harvester and connected to the belt via a pulley. When the silage harvester is running, the belt drives the fine crushing roller to rotate, achieving fine crushing. The fine crushing roller is mostly designed as an integrated unit. When hard objects such as stones are mixed into the corn stalks, the hard objects can easily cause local damage to the crushing teeth on the fine crushing roller. After damage, the entire fine crushing roller is usually replaced. However, the crushing teeth in the undamaged parts of the fine crushing roller still have normal function. Directly replacing the whole unit would result in a large waste of resources. Therefore, this application provides a grain crusher for a silage harvester to meet the needs. Utility Model Content

[0004] This invention provides a grain crusher for silage harvesters to solve the problem of significant resource waste caused by directly replacing the entire fine crushing roller.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A grain crusher for a silage harvester includes a crushing roller and two end seats. Crushing side rollers are connected to both ends of the crushing roller. A fixing mechanism is provided inside the crushing roller. The crushing side rollers are fitted onto the fixing mechanism and cooperate with the crushing roller to form a fine crushing roller. The crushing side rollers are fixedly connected to the end seats through the fixing mechanism.

[0006] Preferably, the fixing mechanism includes multiple square bars fixed to the inner wall of the crushing roller, with positioning posts fixed at both ends of the square bars. A set of rings is fixed to the inner wall of the crushing side roller, with multiple rings in each set. The rings are movably sleeved on the positioning posts, with the side of the rings near the end seat fitting against the side of the end seat. A screw is fixed to the end of the positioning post away from the square bars, and the screw passes through the end seat and is threadedly connected to a nut, which presses against the side of the end seat.

[0007] Preferably, the fixing mechanism further includes a positioning component, which includes a connecting strip fixed between two adjacent square strips. The connecting strip is fixed to the inner wall of the crushing roller. A slot is provided on the side of the connecting strip. A connecting seat is fixed on the side of the annular ring near the connecting strip. An insert is fixed on the side of the connecting seat and inserted into the slot.

[0008] Preferably, the insert is in the shape of a frustum, and the shape of the slot is adapted to the shape of the insert.

[0009] Preferably, a connecting rib is fixed to the side of the connecting seat. The connecting rib is fixed to the side of the ring, the connecting rib is arc-shaped, and the center of the connecting rib is located on the central axis of the ring.

[0010] Preferably, the length and width of the connector on the side away from the insert block are greater than the length and width of the insert block on the side closer to the ring.

[0011] Preferably, the positioning assembly further includes a positioning ring fixed to the end of the crushing side roller, and an annular groove is provided at the end of the crushing middle roller, into which the positioning ring is inserted.

[0012] Preferably, the outer wall of the positioning ring has an inclined surface that fits against the inner wall of the annular groove.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting up a crushing middle roller and crushing side rollers, the fine crushing roller consists of two crushing side rollers and one crushing middle roller. When the crushing teeth on the crushing middle roller or crushing side roller are damaged, the crushing middle roller or crushing side roller can be replaced separately without replacing the entire fine crushing roller, thus avoiding a large waste of resources.

[0014] By setting insert blocks, after the crushing side roller is fixed at the end of the crushing middle roller, the insert blocks on the ring are inserted into the slots in the connecting strip, which improves the connection strength at the connection between the crushing middle roller and the crushing side roller, thereby improving the connection stability between the crushing middle roller and the crushing side roller and ensuring the synchronous operation of the crushing middle roller and the crushing side roller.

[0015] By setting connecting blocks and connecting ribs, the contact area between the insert and the ring is increased, thereby improving the connection strength between the insert and the ring and preventing cracking or deformation at the connection point.

[0016] By setting a positioning ring, after the crushing side roller is fixed at the end of the crushing middle roller, the positioning ring is inserted into the annular groove, and the inclined surface of the outer wall of the positioning ring is in close contact with the inner wall of the annular groove, ensuring the concentricity of the crushing middle roller and the crushing side roller, thereby ensuring the crushing accuracy of the fine crushing roller on corn stalks and seeds.

Detailed Implementation

[0020] The following is a detailed description of a grain crusher for a silage harvester provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0021] like Figures 1-7As shown in the figure, an embodiment of this utility model provides a grain crusher for a silage harvester, including a crushing roller 1 and two end seats 3. Crushing side rollers 2 are connected to both ends of the crushing roller 1. A fixing mechanism 4 is provided inside the crushing roller 1. The crushing side rollers 2 are fitted onto the fixing mechanism 4 and cooperate with the crushing roller 1 to form a fine crushing roller. The crushing side rollers 2 are fixedly connected to the end seats 3 through the fixing mechanism 4. The fixing mechanism 4 provides a precise connection and stable fixation for the crushing roller 1 and the crushing side rollers 2, ensuring that the two operate synchronously and avoiding relative sliding that could lead to crushing failure. The end seats 3 press the crushing side rollers 2 tightly through the fixing mechanism 4, further enhancing the connection stability. The combined design of the fine crushing rollers allows for targeted replacement when either the crushing roller 1 or the crushing side roller 2 is damaged, without having to replace the entire roller body, greatly reducing resource waste and maintenance costs.

[0022] like Figure 2 and Figure 4 As shown, in this embodiment, the fixing mechanism 4 includes multiple square bars 5 fixed to the inner wall of the crushing roller 1. Positioning posts 6 are fixed to both ends of each square bar 5. A set of rings 7 is fixed to the inner wall of the crushing side roller 2. Each set of rings 7 consists of multiple rings, which are movably fitted onto the positioning posts 6. The side of the ring 7 closest to the end seat 3 is in contact with the side of the end seat 3. A screw is fixed to the end of the positioning post 6 away from the square bars 5. The screw passes through the end seat 3 and is threaded with a nut. The nut presses against the side of the end seat 3. The square bars 5 are fixed to the inner wall of the crushing roller 1, which enhances the structural strength of the crushing roller 1 and prevents… To prevent deformation due to excessive force during crushing operations, and to provide a stable installation base for the positioning column 6, the positioning column 6 and the ring 7 are fitted together to provide precise positioning for the crushing side roller 2, ensuring the accurate relative position of the crushing side roller 2 and the crushing middle roller 1, and ensuring concentricity. Multiple rings 7 are distributed along the inner wall of the crushing side roller 2, which can disperse the force on the crushing side roller 2 and avoid local stress concentration that could damage the rings 7. The threaded connection between the screw and the nut can ensure the clamping force of the end seat 3 on the rings 7, which not only ensures that the crushing side roller 2 is firmly fixed, but also facilitates disassembly and replacement later, making the operation convenient and the fixation reliable.

[0023] like Figure 4 and Figure 6As shown in this embodiment, the fixing mechanism 4 further includes a positioning component 8. The positioning component 8 includes a connecting strip 9 fixed between two adjacent square strips 5. The connecting strip 9 is fixed to the inner wall of the crushing roller 1. A slot 14 is provided on the side of the connecting strip 9. A connecting seat 11 is fixed on the side of the ring 7 near the connecting strip 9. An insert 10 is fixed on the side of the connecting seat 11. The insert 10 is inserted into the slot 14. The connecting strip 9 connects the adjacent square strips 5, which can enhance the connection strength between the square strips 5, making the inner wall structure of the crushing roller 1 more stable. At the same time, it provides a carrier for the opening of the slot 14. The insertion of the insert 10 and the slot 14 can limit the relative rotation of the crushing side roller 2 and the crushing roller 1, ensuring that the two operate synchronously and avoiding slippage of the crushing side roller 2 due to crushing resistance. This ensures crushing efficiency and particle size uniformity. The connecting seat 11 increases the connection area between the insert 10 and the ring 7, improves the fixing stability of the insert 10, prevents the insert 10 from falling off the ring 7 under long-term stress, and further enhances the reliability of the positioning component 8.

[0024] like Figure 7 As shown in this embodiment, the insert 10 is in the shape of a frustum, and the shape of the slot 14 is adapted to the shape of the insert 10. The frustum-shaped insert 10 and the adapted slot 14 cooperate with each other, which has better guidance and more stable fit compared with the rectangular shape. During installation, the insert 10 can automatically align with the slot 14, reducing the difficulty of alignment and improving the assembly efficiency. The frustum structure makes the side of the insert 10 fit tightly against the inner wall of the slot 14 after it is inserted into the slot 14, reducing gaps, enhancing the fixing effect, and preventing the crushing side roller 2 from rotating slightly.

[0025] like Figure 7 As shown in this embodiment, a connecting rib 12 is fixed to the side of the connecting seat 11. The connecting rib 12 is fixed to the side of the ring 7. The connecting rib 12 is arc-shaped, and the center of the connecting rib 12 is located on the central axis of the ring 7. The shape of the arc-shaped connecting rib 12 is adapted to the arc-shaped side of the ring 7, which can increase the contact area between the connecting seat 11 and the ring 7, improve the connection strength between the two, distribute the force at the connection, and prevent the connection between the connecting seat 11 and the ring 7 from cracking due to excessive local force.

[0026] like Figure 7 As shown in this embodiment, the length and width of the side of the connector 11 away from the plug 10 are greater than the length and width of the side of the plug 10 close to the ring 7. Compared with the plug 10 being directly connected to the ring 7, the connector 11 increases the contact area between the plug 10 and the ring 7, thus improving the fixing firmness of the plug 10.

[0027] like Figure 3As shown in this embodiment, the positioning component 8 also includes a positioning ring 13 fixed to the end of the crushing side roller 2. The end of the crushing middle roller 1 is provided with an annular groove. The positioning ring 13 is inserted into the annular groove. The positioning ring 13 and the annular groove are embedded and cooperated to further restrict the relative displacement of the crushing side roller 2 and the crushing middle roller 1 in the radial direction, ensuring their concentricity. The positioning ring 13 can also fill the gap between the ends of the crushing side roller 2 and the crushing middle roller 1, preventing debris from entering the gap during the crushing process.

[0028] like Figure 3 As shown in this embodiment, the outer wall of the positioning ring 13 is provided with an inclined surface, which fits against the inner wall of the annular groove. The inclined surface of the outer wall of the positioning ring 13 fits against the inner wall of the annular groove to form a conical surface fit structure. Compared with the straight surface fit, it has a better concentricity calibration effect. The inclined surface fit can also increase the contact area between the positioning ring 13 and the annular groove, enhance the radial fixing effect, prevent the crushing side roller 2 from radially jumping during high-speed operation, and ensure crushing accuracy. At the same time, the inclined surface structure makes it easier for the positioning ring 13 to be inserted into the annular groove, reducing jamming during installation and reducing assembly difficulty.

[0029] Working principle: The crushing roller 1 and two crushing side rollers 2 form a fine crushing roller, which is used for fine crushing of corn stalks and seeds. Multiple square bars 5 are fixed on the inner wall of the crushing roller 1. The positioning posts 6 at both ends of the square bars 5 provide the installation reference for the crushing side rollers 2. The crushing side rollers 2 are put on the positioning posts 6, so that multiple rings 7 fixed on the inner wall of the crushing side rollers 2 are put on the positioning posts 6. At this time, the insert 10 on the side of the ring 7 near the crushing roller 1 is inserted into the slot 14 on the side of the connecting strip 9. The insert 10 is in the shape of a truncated pyramid and is adapted to the shape of the slot 14, so that it can be tightly embedded in the slot 14. Then, the end seat 3 is put on the screw and fits against the ring 7 away from the crushing roller 1. The nut is tightened on the screw, so that the nut presses the end seat 3. Through the compression of the end seat 3 and the ring 7, the crushing side rollers 2 are fixed to both ends of the crushing roller 1, thus completing the assembly of the fine crushing roller. After the crushing side roller 2 is fixed at the end of the crushing middle roller 1, the positioning ring 13 at the end of the crushing side roller 2 is inserted into the annular groove at the end of the crushing middle roller 1. The inclined surface of the outer wall of the positioning ring 13 is in close contact with the inner wall of the annular groove, which can ensure the concentricity of the crushing middle roller 1 and the crushing side roller 2, ensure the smooth operation of the fine crushing roller as a whole, and thus ensure the crushing accuracy of corn stalks and seeds, and avoid uneven crushing particle size due to eccentricity. When the crushing teeth on the crushing roller 1 or the crushing side roller 2 are damaged, unscrew the nut on the screw of the positioning post 6, remove the end seat 3, move the crushing side roller 2 to separate the ring 7 from the positioning post 6. After separation, the crushing roller 1 and the crushing side roller 2 can be separated. After separation, the crushing roller 1 or the crushing side roller 2 can be replaced. After replacement, repeat the above installation steps to assemble the fine crushing roller.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
