[0029] like Figure 1-3 As shown, the present invention provides a method for judging the quality of a chain, the method comprising sleeve-arranging two deformable plates at the two ends of a connecting pin of the chain, respectively, wherein the chain is an agricultural machinery chain with bucket teeth;

[0030] The inner walls on both sides of the bucket teeth are knocked and pressed a set number of times by the judging device, so that the inner walls on both sides of the bucket teeth are deformed, so as to obtain the deformation size of the inner walls on both sides of the bucket teeth;

[0031] The obtained deformation size is compared with the set deformation size to determine whether the chain is qualified.

[0032] The following is a detailed description

[0033] In one embodiment of the present invention, the judgment device includes a frame 4, a deformation structure 1 connected to the frame 4, and two feedback structures 2, wherein:

[0034] The feedback structure 2 includes an annular deformable plate 21, and a through hole 211 is formed on the deformable plate 21. The deformable plate 21 can be sleeved on both ends of the connecting pin 31 of the agricultural machinery chain 3, wherein the deformable plate 21 is made of metal aluminum;

[0035] The deformation structure 1 includes a knocking component 11 , and the knocking component 11 is used to knock the inner walls 321 on both sides of the bucket teeth 32 of the agricultural machinery chain 3 .

[0036] In one embodiment of the present invention, the feedback structure 2 also includes a connecting frame 22 and a bolt 23, wherein the connecting frame 22 is funnel-shaped, and one end of the connecting frame 22 is connected to the deformation plate 21, and the other end of the connecting frame 22 is connected to the output end of the motor 25, so that the deformation plate 21 can be sleeved on the outer periphery of the corresponding end of the connecting pin 31.

[0037] In addition, in this embodiment, in order to study the agricultural machinery chain in the laboratory and judge the quality of multiple agricultural machinery chains in the laboratory, the connecting pins 31 of the multiple agricultural machinery chains can also be threaded. At this time, a first threaded hole can also be opened at the center of the other end of the connecting frame 22, and a bolt 23 can be connected to the output end of the motor 25. The bolt 23 can be screwed into the first threaded hole, and the tail of the bolt 23 can be inserted into the second threaded hole 311 opened on the connecting pin 31.

[0038] In this embodiment, when the bolt 23 rotates, its tail can penetrate into the second threaded hole 311 opened on the connecting pin 31, so that the two deformable plates 21 can be sleeved on the outer periphery of the two connecting pins 31 through the connecting frame 22, so that the two deformable plates 21 can be against the outer walls of the two sides of the bucket tooth 32.

[0039] In this embodiment, the feedback structure 2 also includes a first hydraulic cylinder 24, a motor 25 and a fixing frame 26, wherein the output end of the motor 25 can be connected to the head of the bolt 23, the first hydraulic cylinder 24 is connected to the fixing frame 26, the output of the first hydraulic cylinder 24 is connected to the motor 25, and the fixing frame 26 is connected to the frame 4.

[0040] In this embodiment, by controlling the first hydraulic cylinder 24, the connecting frame 22 and the bolt 23 can be moved toward the direction close to the bucket tooth 32, and when the tail of the bolt 23 just penetrates into the second threaded hole 311, the motor 25 is turned on to rotate the tail of the bolt 23, so that the deformation plate 21 can be tightly fitted with the outer wall of the bucket tooth 32.

[0041] In this embodiment, the fixing frame 26 includes a stabilizing plate 261, a guide rod 262, two oblique rods 263 and two stabilizing rods 264, wherein the two oblique rods 263 are both connected to the frame 4, and the stabilizing plate 261 is connected to the two oblique rods 263; one end of one of the stabilizing rods 264 is connected to the frame 4, and the other end is connected to one of the oblique rods 263; one end of the other stabilizing rod 264 is connected to one of the oblique rods 263, and the other end is connected to the other oblique rod 263.

[0042] The guide rod 262 is connected to the bottom of the stabilizing plate 261 through a fixing seat, the first hydraulic cylinder 24 is fixedly connected to the guide rod through a connecting rod, a sliding sleeve 251 is provided on the top of the motor 25, and the sliding sleeve 251 is sleeved on the guide rod 262 and can slide between the guide rod 262.

[0043] In one embodiment of the present invention, the striking assembly 11 includes a stabilizing frame 111, two cylinders 112, two arc-shaped rods 113 and two connecting plates 114, wherein:

[0044] The stabilizing frame 111 is connected to the frame 4, the two connecting plates 114 are connected to the frame 4 through connecting rods, the two arc rods 113 are respectively hinged on the two connecting plates 114, and the two cylinders 112 are respectively hinged on the stabilizing frame 111; the output ends of the two cylinders 112 are respectively connected to the two arc rods 113, and the bottom of the arc rod 113 is connected to a knocking ball 1131.

[0045] In this embodiment, since the output end of the cylinder 112 moves very quickly, when the output end of the cylinder 112 extends, since the bottom of the corresponding arc rod 113 is connected with a knocking ball 1131, and the knocking ball 1131 is made of a hard material (for example, steel material, etc.), the knocking ball 1131 can quickly knock the inner wall 321 on the corresponding side of the bucket tooth 32. During the continuous knocking process, the inner wall 321 on the opposite side of the bucket tooth 32 can be knocked and deformed.

[0046] In one embodiment of the present invention, the deformation structure 1 also includes a support frame 12, two second hydraulic cylinders 13 and two pressure blocks 14, wherein the support frame 12 is connected to the stabilizing frame 111, the two second hydraulic cylinders 13 are connected to the support frame 12, and the two pressure blocks 14 are respectively connected to the output ends of the two second hydraulic cylinders 13, and the two second hydraulic cylinders 13 are symmetrically distributed.

[0047] In this embodiment, the outer surface of the pressure block 14 is a curved surface.

[0048] In this embodiment, by controlling the corresponding second hydraulic cylinder 13, the corresponding pressure block 14 can be moved toward the inner wall 321 on the corresponding side of the bucket tooth 32, and finally the inner wall 321 on the corresponding side of the bucket tooth 32 can be squeezed, so that the inner wall 321 on the corresponding side of the bucket tooth 32 can also be squeezed and deformed.

[0049] It should be understood that, in this embodiment, the pressure block 14 and the corresponding striking ball 1131 can work in a staggered manner, for example, Figure 2 The knocking ball 1131 on the left side is retracted after being rotated counterclockwise by the cylinder 112. At this time, the corresponding second hydraulic cylinder 13 can be controlled to move, so that the corresponding pressure block 14 moves toward the inner wall 321 on the corresponding side of the bucket tooth 32 and can squeeze the inner wall 321 on the corresponding side of the bucket tooth 32.

[0050] In the present invention, by knocking the inner wall 321 on the corresponding side of the bucket tooth 32 with the knocking ball 1131 and by the pressure block 14 exerting pressure on the inner wall 321 on the corresponding side of the bucket tooth 32, the inner wall 321 corresponding to the bucket tooth 32 is simulated to be knocked and squeezed in the actual process, so that the inner wall 321 corresponding to the bucket tooth 32 can be deformed. Since the deformation plate 21 is made of metal aluminum, it is relatively soft (the thickness of the deformation plate 21 can be changed according to demand) and fits the inner wall 321 corresponding to the bucket tooth 32 from the outside. Therefore, when the inner wall 321 corresponding to the bucket tooth 32 is deformed, the deformation plate 21 is also deformed accordingly.

[0051] When detecting whether the bucket teeth 3 of the agricultural machinery chain 3 are qualified, it is only necessary to knock the set number of times by the knocking ball 1131 and the set number of times by the pressure block 14, and then compare the deformation size of the deformation plate 21 with the set deformation size under the set number of knocking and pressure (this comparison can be done through manual observation or by scanning the deformation plate 21 with some existing equipment to obtain the deformation size of the deformation plate 21, which will not be elaborated here), thereby determining whether the bucket teeth 3 of the agricultural machinery chain 3 are qualified. For example, if the deformation size is not greater than the set deformation size, it means that it is qualified.

[0052] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
