[0033] The top plate 141, bottom plate 15, and at least one pair of vertical plates 16 can all be constructed using scrap materials such as structural steel. This results in a robust and durable jig for assembling and disassembling the rotary screen tractor bearing. Each pair of vertical plates 16 is fixedly connected to the top plate 141 and the bottom plate 15.

[0034] For example, Figure 1 The image shows a pair of upright plates 16. In this embodiment of the invention, multiple pairs of upright plates may be provided according to the force application requirements (to improve the sturdiness of the tooling). This embodiment of the invention is not limited in this respect.

[0035] In some embodiments, such as Figure 1 As shown, the main body 10 of the square frame includes a pair of upright plates 16, the pair of upright plates 16 including a first upright plate 161 and a second upright plate 162; the top plate 141 and the bottom plate 15 are arranged in parallel, the first upright plate 161 and the second upright plate 162 are arranged in parallel; the first upright plate 161, the top plate 141, the second upright plate 162 and the bottom plate 15 are arranged in sequence to form an accommodating space 18.

[0036] Thus, by setting the first vertical plate 161 and the second vertical plate 162, the first vertical plate 161, the top plate 141, the second vertical plate 162 and the bottom plate 15 can be enclosed to form an accommodating space 18, so as to prepare a rotary screen tractor bearing disassembly and assembly tooling.

[0037] In some embodiments, such as Figure 1 As shown, the square frame body 10 also includes: a front side plate 142 and a rear side plate 143 arranged opposite to each other, both of which are connected to the top plate 141; at least one pair of upright plates 16 are located between the front side plate 142 and the rear side plate 143, and are fixedly connected to the front side plate 142 and the rear side plate 143.
