[0022] In order to be able to more clearly understand the technical means of the present utility model and implement it according to the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0023] See Figures 1-5 , this specific embodiment discloses a tractor for quickly replacing a belt, including: a support frame 1, a main traction roller 2, a driven traction roller 3, a common transition roller 4, and a perforated triangular belt 5. One end of the support frame 1 is hingedly installed with a turning plate 7 through a connecting block 6. The upper part of the turning plate 7 is fixedly connected with a triangular mounting plate 8. The triangular mounting plate 8 is provided with a plurality of mounting holes 8-1. Both ends of the driven traction roller 3 are respectively installed with a first adjusting plate 9 and a second adjusting plate 10. The first adjusting plate 9 is fixedly connected to the triangular mounting plate 8 through the mounting hole 8-1. Among them, the plurality of mounting holes 8-1 on the triangular mounting plate 8 are used for locking a plurality of components fixed on the triangular mounting plate 8.

[0024] More specifically, the support frame includes a left vertical plate 1-1, a right vertical plate 1-2, and a cross beam 1-3 located between the left vertical plate and the right vertical plate. The top of the left vertical plate 1-1 is fixedly connected with an inverted T-shaped positioning block 11. The vertical part of the inverted T-shaped positioning block 11 is used for limiting the turning of the turning plate 7 to the vertical position to ensure the assembly accuracy.

[0025] More specifically, the right vertical plate 1-2 is provided with a plurality of adjusting holes 1-2-1. The second adjusting plate 10 is fixedly installed on the right vertical plate 1-2 of the support frame. The first adjusting plate 9 can adjust the installation position on the triangular mounting plate 8 through a plurality of mounting holes 8-1. The second adjusting plate 10 can adjust the installation position on the right vertical plate 1-2 through a plurality of adjusting holes 1-2-1. By setting the first adjusting plate 9 and the second adjusting plate 10, the installation position of the driven traction roller 3 is adjusted, and finally the tension of the perforated triangular belt 5 is adjusted.

[0026] More specifically, the triangular mounting plate 8 is an inverted triangular mounting plate. The triangular mounting plate 8 is also fixedly connected with a common transition roller bearing seat 4-1 through the mounting hole 8-1. The first adjusting plate 9 is further fixedly connected with a driven traction roller bearing seat 3-1. The main traction roller 2, the driven traction roller 3, and the common transition roller 4 are arranged in an inverted triangle, and the common transition roller 4 is installed below the main traction roller 2 and the driven traction roller 3.

[0027] More specifically, a first limiting plate 9-1 is provided on one side of the first adjusting plate 9, and a second limiting plate 10-1 is provided on one side of the second adjusting plate 10. The first limiting plate 9-1 and the second limiting plate 10-1 are used for auxiliary positioning after the first adjusting plate 9 and the second adjusting plate 10 are fixed to a predetermined position by fasteners such as bolts, to prevent the first adjusting plate 9 and the second adjusting plate 10 from moving and affecting the tension accuracy.

[0028] More specifically, on one side of the traction idler roller bearing block 3-1 and the common transition roller bearing block 4-1, there are respectively provided third limit plates 3-4-1. Similar to the working principles of the first and second limit plates, the setting of the third limit plates 3-4-1 is used for the auxiliary positioning after the traction idler roller bearing block 3-1 and the common transition roller bearing block 4-1 are fixed to the predetermined positions through fasteners such as bolts, so as to prevent the traction idler roller bearing block 3-1 and the common transition roller 4-1 from moving and affecting the tensioning accuracy. In this specific embodiment, through the combined setting of the first limit plate 9-1, the second limit plate 10-1, and the third limit plate 3-4-1, the positioning position is guaranteed to the greatest extent, and the tensioning stability of the device is extremely improved.

[0029] More specifically, the middle part of the turning plate 7 is a guide groove, and a number of positioning pin shafts 7-1 are fixedly connected to the turning plate. After the perforated triangular belt 5 is assembled, the positioning pin shafts 7-1 fixedly connect the turning plate 7 and the triangular mounting plate 8. The positioning pin shafts 7-1 can ensure that the accuracy remains unchanged after reinstallation, which is convenient for operation and improves the efficiency of belt replacement operation mode.

[0030] More specifically, the guide groove is a U-shaped groove, which is used for the assembly of the bottom common transition roller and its bearing block to avoid interference in the installation position.

[0031] More specifically, the number of a number of positioning pin shafts 7-1 is 2, and they are symmetrically distributed on both sides of the U-shaped groove, so that the locking force is evenly distributed.

[0032] More specifically, there is a hinge shaft 6-1 between the connecting block 6 and the turning plate 7 to realize the smooth rotation of the turning plate 7.

[0033] The working principle of the present utility model is as follows:

[0034] The traction machine of the present utility model is made into a hinged and openable mechanism on one side of the perforated triangular belt. When it is necessary to replace the perforated triangular belt 5, the inverted T-shaped positioning block 11 and the positioning pin shaft 7-1 are disassembled, the turning 7 plate is opened, and the installation positions of the first adjusting plate 9 and the second adjusting plate 10 are adjusted. After the perforated triangular belt is loosened, it can be disassembled and replaced. When the perforated triangular belt 5 is reinstalled, the inverted T-shaped positioning block 11 and the positioning pin shaft 7-1 are reinstalled, the installation positions of the first adjusting plate 9 and the second adjusting plate 10 are adjusted, the belt is tensioned, and the accuracy remains unchanged after reinstallation, which is convenient for operation and greatly improves the efficiency of the traction machine to replace the belt.

[0035] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
