[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] As attached Figure 1 To the attached Figure 5 As shown:

[0027] Embodiment 1: The present invention provides a hydraulic motor driven reel speed adjustable ratio device, comprising:

[0028] A follower shaft 4 is provided with a follower belt fixed plate 3 on the periphery of the follower shaft 4, and a follower belt driven plate 5 is movably provided on the periphery of the follower shaft 4 on one side of the follower belt fixed plate 3;

[0029] An oil pump 11 is connected to one side of the follower shaft 4. A high-pressure oil delivery pipe 19 is installed on the surface of the oil pump 11. The top of the high-pressure oil delivery pipe 19 is connected to the motor 12. An oil supply pipe 18 is installed on the surface of the oil pump 11. The bottom of the oil supply pipe 18 is connected to the oil tank 17.

[0030] Adjusting arm 2, the adjusting arm 2 is installed at both ends of the follower shaft 4, the top of the adjusting arm 2 is movably connected to the telescopic electric cylinder 1, and the bottom of the adjusting arm 2 is movably connected to the adjusting arm support 6;

[0031] A transmission shaft 9 is provided with a transmission leather driven disc 7 movably mounted on the periphery of the transmission shaft 9. A transmission belt fixed disc 8 is mounted on the periphery of the transmission shaft 9 on one side of the transmission leather driven disc 7. A spring pressing piece 14 is mounted on the periphery of the transmission shaft 9 on the other side of the transmission leather driven disc 7. A spring 13 is mounted between the spring pressing piece 14 and the transmission leather driven disc 7.

[0032] The top of the V-belt 15 is sleeved between the follower belt fixed plate 3 and the follower belt driving plate 5, and the bottom of the V-belt 15 is sleeved between the transmission belt driving plate 7 and the transmission belt fixed plate 8.

[0033] The transmission shaft 9 is connected to an external power mechanism.

[0034] As can be seen from the above, the thrust of the spring 13 makes the transmission belt drive plate 7 close to the transmission belt fixed plate 8, and the transmission shaft 9 rotates under the drive of the external power mechanism. During the rotation of the transmission shaft 9, the transmission belt fixed plate 8 is driven to rotate at the same time, and the V-belt 15 is driven to rotate in cooperation with the transmission belt drive plate 7. During the rotation of the V-belt 15, the follower belt fixed plate 3 and the follower belt drive plate 5 on the follower shaft 4 are driven to rotate at the same time, thereby driving the follower shaft 4 to rotate and realizing power transmission. During the rotation of the follower shaft 4, power transmission is provided to the oil pump 11. During the operation of the oil pump 11, the liquid inside the oil tank 17 is extracted through the oil supply pipe 18, and the liquid is transported to the inside of the motor 12 through the high-pressure oil pipe 19, providing power for the operation of 12;

[0035] When the adjusting arm 2 is turned, the adjusting arm 2 is pushed and the follower leather driving plate 5 is squeezed, and the follower leather driving plate 5 moves laterally on the follower shaft 4 under the push of the adjusting arm 2, thereby adjusting the clamping force of the follower belt fixed plate 3 and the follower leather driving plate 5 on the V-belt 15. The greater the clamping force of the follower belt fixed plate 3 and the follower leather driving plate 5 on the V-belt 15, the better the power transmission effect between the transmission shaft 9 and the follower shaft 4. Conversely, when the clamping force of the follower belt fixed plate 3 and the follower leather driving plate 5 on the V-belt 15 is reduced, the power transmission effect between the transmission shaft 9 and the follower shaft 4 is reduced, and the speed of the oil pump 11 changes, so that the speed of the motor 12 changes accordingly, thereby achieving the function of adjusting the speed of the motor 12 according to demand.

[0036] Specifically, regarding the above-mentioned adjustment arm 2, the adjustment arm 2 is located on one side of the follower belt drive plate 5, and a protruding column is installed at one end of the adjustment arm 2 that is close to each other.

[0037] The bosses are located at both ends of the follower belt driving disc 5 .

[0038] As can be seen from the above, the contact area between the adjusting arm 2 and the follower belt drive plate 5 can be expanded by the protruding column, so that the adjusting arm 2 can apply pressure to the follower belt drive plate 5 during the turning process.

[0039] Specifically, regarding the transmission belt fixed plate 8 , a locking pin 16 is installed on the surface of the transmission belt fixed plate 8 , and a rear end of the locking pin 16 penetrates the transmission belt fixed plate 8 and is connected to the transmission shaft 9 .

[0040] The transmission shaft 9 is provided with a hole for installing the locking pin 16 .

[0041] As can be seen from the above, by passing the locking pin 16 through the transmission belt fixed plate 8 and connecting it with the transmission shaft 9, the position of the transmission belt fixed plate 8 on the transmission shaft 9 is limited after connection, thereby achieving synchronous rotation of the transmission belt fixed plate 8 and the transmission shaft 9, thereby improving the power transmission capacity.

[0042] Specifically, regarding the above-mentioned spring 13, the spring 13 is sleeved on the periphery of the transmission shaft 9, and both sides of the spring 13 are connected to the spring pressing plate 14 and the transmission belt drive plate 7 respectively.

[0043] As can be seen from the above, the thrust of the spring 13 can limit the position of the transmission belt drive plate 7 on the transmission shaft 9, thereby improving the clamping effect of the transmission belt drive plate 7 and the transmission belt fixed plate 8 on the V-belt 15.

[0044] The working principle of this embodiment is as follows: by passing the lock pin 16 through the transmission belt fixed plate 8 and connecting it with the transmission shaft 9, the transmission shaft 9 is driven to rotate by the external power mechanism, and the transmission shaft 9 drives the transmission belt fixed plate 8 to rotate at the same time during the rotation of the transmission shaft 9, and drives the V-belt 15 to rotate in cooperation with the transmission belt driven plate 7. During the rotation of the V-belt 15, the follower belt fixed plate 3 and the follower belt driven plate 5 on the follower shaft 4 are driven to rotate at the same time, thereby driving the follower shaft 4 to rotate and realizing power transmission. During the rotation of the follower shaft 4, power transmission is provided to the oil pump 11. During the operation of the oil pump 11, the liquid inside the oil tank 17 is extracted through the oil supply pipe 18, and the liquid is transported to the inside of the motor 12 through the high-pressure oil pipe 19, providing power for the operation of 12;

[0045] During the operation of the telescopic electric cylinder 1, the adjusting arm 2 is pushed to flip with the adjusting arm support 6 as the fulcrum. During the flipping process of the adjusting arm 2, the follower leather driving plate 5 is squeezed, and the follower leather driving plate 5 is pushed by the adjusting arm 2 to move laterally on the follower shaft 4, thereby adjusting the clamping force of the follower belt fixed plate 3 and the follower leather driving plate 5 on the V-belt 15. After adjustment, the effect of power transmission between the drive shaft 9 and the follower shaft 4 is controlled, and the change in the number of revolutions of the oil pump 11 causes the speed of the motor 12 to change accordingly, thereby achieving the function of adjusting the speed of the motor 12 according to demand.

[0046] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that one side of the follower shaft 4 is connected to a coupling 10, and one side of the coupling 10 is connected to an oil pump 11;

[0047] An oil return port is provided on the surface of the motor 12 , and the oil return port is connected to the oil tank 17 via an oil return pipe 20 .

[0048] As can be seen from the above, the coupling 10 connects the follower shaft 4 and the oil pump 11 and allows them to rotate together, thereby transmitting torque. The liquid in the motor 12 can be discharged back into the oil tank 17 through the return oil pipe 20, saving energy.

[0049] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
