[0042] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0043] Example 1

[0044] like Figures 1 to 9 As shown, a sharpening guide rail seat calibration device of this embodiment is used to calibrate the sharpening guide rail seat 100 of the shredder assembly. It includes a positioning seat 200 and a measuring rod 201. The positioning seat 200 is mounted on the grindstone assembly mechanism 400 of the shredder assembly, and the measuring rod 201 is pluggable and mounted on the positioning seat 200. The two ends of the sharpening guide rail seat 100 are respectively detachably mounted on the housing weld 300 of the shredder assembly.

[0045] Among them, one side of the whetstone assembly mechanism 400 is slidably connected to the guide rail column 301 horizontally arranged in the shell weld 300, and can move axially and circumferentially along the guide rail column 301; the other side of the whetstone assembly mechanism 400 can move along the sharpening guide rail seat 100; the shell weld 300 is also provided with a first abutment limit portion 302 and a second abutment limit portion 303 located at the same height, and the first abutment limit portion 302 and the second abutment limit portion 303 are respectively located at the starting point and the end point of the movement of the whetstone assembly mechanism 400 along the sharpening guide rail seat 100; the measuring rod 201 is arranged perpendicular to the guide rail column 301, one end of the measuring rod 201 extends out from the outside of the upper end of the shell weld 300, and the other end of the measuring rod 201 extends into the shell weld 300 and is used to adapt and abut with the first abutment limit portion 302 or the second abutment limit portion 303.

[0046] like Figure 1 、 Figure 2 、 Figure 4 and Figure 6As shown, the positioning seat 200 of this embodiment is circular, and an axially extending insertion hole is provided at the center of the positioning seat 200. The measuring rod 201 is pluggable and disposed in the insertion hole of the positioning seat 200. The measuring rod 201 and the insertion hole can be a transition fit to ensure positioning accuracy and the accuracy of the measured value.

[0047] like Figure 4 As shown, the positioning seat 200 of this embodiment includes a limiting flange 202, a limiting cylinder 203, and a connecting rod 204. The limiting flange 202 is disposed around the outer wall of one end of the limiting cylinder 203, and the connecting rod 204 is fixed to the inner wall of one end of the limiting cylinder 203. The center of the limiting cylinder 203 is provided with an insertion hole that passes through the connecting rod 204. The structural configuration of the positioning seat facilitates press-fit fixation of the positioning seat, and the positioning seat can be detachably assembled without the need for additional connecting structures.

[0048] like Figure 2 and Figure 6 As shown, the connecting rods 204 of this embodiment are multiple and are fixed radially on the inner side wall of one end of the limiting cylinder 203 with the center of the limiting cylinder 203 as the center of the circle, and the plug hole is provided at the intersection of the multiple connecting rods 204. Preferably, there are three connecting rods 204.

[0049] like Figures 1 to 6 As shown, the whetstone assembly mechanism 400 of this embodiment includes a ratchet 401 and a guide sleeve 402, the outer wall of the guide sleeve 402 is slidingly connected to the guide rail column 301 through a connecting sleeve 403, the axis of the guide sleeve 402 is perpendicular to the guide rail column 301, the ratchet 401 is threadedly connected to the outer wall of the upper end of the guide sleeve 402, and an assembly gap is reserved between the ratchet 401 and the upper end face of the guide sleeve 402, and the positioning seat 200 is crimped and fixed in the assembly gap between the ratchet 401 and the upper end face of the guide sleeve 402; the measuring rod 201 is coaxially arranged with the guide sleeve 402.

[0050] Among them, Figure 6 and Figure 7 As shown, the whetstone assembly mechanism 400 can be brought into rolling contact with the bottom of the sharpening rail base 100 via a roller 405, and the top of the whetstone assembly mechanism 400 can be brought into contact with the top of the sharpening rail base 100 via a support plate 404. The roller 405 can be rotatably connected to one side of the whetstone assembly mechanism 400 via a roller shaft 406. The support plate 404 can be fixed to the top of the whetstone assembly mechanism 400 via bolts.

[0051] The blade sharpening guide rail calibration device of this embodiment is primarily used to adjust the blade sharpening guide rail 100 on the shredder assembly, a common mechanism in silage harvesters. A blade roller weld 304, a left half-shaft 305, and a right half-shaft 306 are disposed within the welded shell 300. The blade roller weld 304 is disposed within the welded shell 300, while the left half-shaft 305 and the right half-shaft 306 are disposed on the left and right walls of the welded shell 300, respectively. The first and second abutment stoppers 302 and 303 of this embodiment can be separate stopper protrusions disposed on the inner wall of the welded shell 300, or they can utilize existing structures on the shredder assembly, such as the left and right inner end caps on the left and right side walls of the welded shell 300. If the welded shell 300 lacks the left and right inner end caps, the measuring rod can be appropriately extended and abutted against the drive shaft within the welded shell 300.

[0052] After the silage machine has harvested a certain amount of forage, the blade of the moving blade will become blunt, and the quality of the forage chopped will decrease, falling below the standards of cattle and sheep farms. Sharpening is required, and the gap between the moving and fixed blades needs to be adjusted to ensure the quality of the forage. During the sharpening process, the sharpening device is required to have a sharpening uniformity, which can not only make the blade of the moving blade sharp, but also make the runout value of the knife roller on the rotating circumference within an acceptable range (that is, the circumferential motion range on the guide rail column is acceptable), and then the required gap between the moving and fixed blades (0.2 to 0.4 mm) can be adjusted. Therefore, it is particularly important to ensure the uniformity of the sharpening. The sharpening guide rail seat calibration device of this embodiment can calibrate the sharpening guide rail seat by setting a positioning seat and a measuring rod, so as to ensure that after sharpening, the moving blade on the knife roller is uniform and meets the forage chopped quality.

[0053] This embodiment also provides a knife sharpening guide rail seat calibration method, which is implemented using the knife sharpening guide rail seat calibration device described above, and includes the following steps:

[0054] S1: After assembling the calibration device for the sharpening rail seat 100, place the sharpening stone assembly mechanism 400 at the beginning of the sharpening rail seat 100. Insert the measuring rod 201 into the positioning seat 200, with the lower end of the measuring rod 201 abutting against the first abutting stop 302. Measure the distance X between the upper end of the measuring rod 201 and the upper surface of the positioning seat 200, and then remove the measuring rod 201 from the positioning seat 200.

[0055] S2: Push the whetstone assembly mechanism 400 from one end of the guide rail post 301 to the other end. Simultaneously, the whetstone assembly mechanism 400 also moves along the sharpening guide rail seat 100 from the beginning to the end of the sharpening guide rail seat 100. When the whetstone assembly mechanism 400 is located at the end of the sharpening guide rail seat 100, insert the measuring rod 201 into the positioning seat 200, and make the lower end of the measuring rod 201 abut against the second abutting limiter 303. Measure the distance Y between the upper end of the measuring rod 201 and the upper surface of the positioning seat 200.

[0056] S3, calculate the absolute value of the difference between X and Y as Z, and compare Z with a preset error value (the preset error value can be 0.1mm). If Z is not greater than the preset error value, the sharpening guide rail seat 100 is not offset; if Z is greater than the preset error value, the sharpening guide rail seat 100 is offset and needs to be adjusted.

[0057] The knife sharpening guide rail seat calibration method of this embodiment can calibrate whether the knife sharpening guide rail seat is offset.

[0058] Example 2

[0059] Based on the knife sharpening guide rail seat calibration device of Example 1, the knife sharpening guide rail seat calibration device of this embodiment is further provided with an adjustment component, and the two ends of the knife sharpening guide rail seat 100 are detachably mounted on the shell weld 300 of the shredding assembly through the adjustment component, and the adjustment component is mounted on the shell weld 300. The two ends of the knife sharpening guide rail seat 100 can be adjusted by the adjustment component to achieve a preset upward and downward deflection angle.

[0060] Specifically, such as Figure 6 and Figure 7 As shown, the adjustment assembly of this embodiment includes an adjustment block 500 and an adjustment bolt 501. The adjustment block 500 is fixed to the housing weld 300. The adjustment block 500 is provided with an adjustment hole. The sharpening guide rail seat 100 is provided with a threaded hole. The adjustment hole and the threaded hole are arranged correspondingly, and the inner diameter of the adjustment hole is larger than the inner diameter of the threaded hole. The adjustment bolt 501 passes through the adjustment hole and is threadedly connected to the threaded hole. The adjustment block and the adjustment bolt cooperate to adjust the inclination of the two ends of the sharpening guide rail seat.

[0061] In a preferred embodiment of this invention, the adjustment block 500 is provided with a plurality of adjustment holes, which are arranged in a vertical sequence; the sharpening guide rail seat 100 is provided with a plurality of threaded holes, which are arranged in a one-to-one correspondence with the plurality of adjustment holes. Preferably, the adjustment block is provided with two adjustment holes, and the sharpening guide rail seat is provided with two threaded holes.

[0062] A knife sharpening guide rail seat calibration method of this embodiment is implemented using the knife sharpening guide rail seat calibration device described above, and includes the following steps:

[0063] S1: After assembling the calibration device for the sharpening rail seat 100, place the sharpening stone assembly mechanism 400 at the beginning of the sharpening rail seat 100. Insert the measuring rod 201 into the positioning seat 200, with the lower end of the measuring rod 201 abutting against the first abutting stop 302. Measure the distance X between the upper end of the measuring rod 201 and the upper surface of the positioning seat 200, and then remove the measuring rod 201 from the positioning seat 200.

[0064] S2: Push the whetstone assembly mechanism 400 from one end of the guide rail post 301 to the other end. Simultaneously, the whetstone assembly mechanism 400 also moves along the sharpening guide rail seat 100 from the beginning to the end of the sharpening guide rail seat 100. When the whetstone assembly mechanism 400 is located at the end of the sharpening guide rail seat 100, insert the measuring rod 201 into the positioning seat 200, and make the lower end of the measuring rod 201 abut against the second abutting limiter 303. Measure the distance Y between the upper end of the measuring rod 201 and the upper surface of the positioning seat 200.

[0065] S3, calculating the absolute value of the difference between X and Y as Z, and comparing Z with a preset error value. If Z is not greater than the preset error value, the sharpening guide rail seat 100 is not offset; if Z is greater than the preset error value, the sharpening guide rail seat 100 is offset and needs to be adjusted using an adjustment component;

[0066] During adjustment, loosen the adjustment component at the higher end of the sharpening guide rail seat 100, lower the higher end of the sharpening guide rail seat 100 by a distance Z, and then tighten the adjustment component; or loosen the adjustment component at the lower end of the sharpening guide rail seat 100, move the lower end of the sharpening guide rail seat 100 up by a distance Z, and then tighten the adjustment component.

[0067] The sharpening guide rail seat calibration method of this embodiment can both calibrate whether the sharpening guide rail seat is offset and adjust the position of the offset sharpening guide rail seat. During the installation of the shredder assembly, after the sharpening stone assembly mechanism is installed, the sharpening stone assembly mechanism can be installed on the sharpening guide rail seat via a support plate and rollers. The height difference between the sharpening guide rail seat and the upper surface of the support plate and roller is small, ensuring that the sharpening stone assembly mechanism does not jump around the guide rail post during the sharpening process, resulting in uneven sharpening of the movable blade. This avoids the phenomenon of the movable blade being fully sharpened on one side while the other side is not, when the sharpening guide rail seat is installed at an angle.
