Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a crawler-type induction adjustment mechanism. Background Art

[0002] The level of agricultural mechanization in my country's hilly and mountainous areas is generally low. Transportation, rotary tillage, ridging, soiling, weeding and other tillage operations are still mainly manual, with a large number of workers and high labor intensity. The proportion of labor input in the total cost of agricultural production is too large, which has become the main factor restricting the development of agricultural production in hilly and mountainous areas. In hilly areas, crawler walking mechanisms are mostly used for mechanical operations. However, due to the fragmentation and large slope of the fields in hilly areas, the walking of the crawler mechanism is greatly hindered. Therefore, a crawler sensing adjustment mechanism is proposed, which can adjust the arch and fall of the crawler according to different terrains. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a crawler type induction adjustment mechanism, which can adjust the arch and fall of the crawler according to different terrains.

[0004] The present invention is achieved through the following technical solutions:

[0005] A crawler-type inductive adjustment mechanism comprises an annular crawler, a driving wheel linked with the crawler and arranged at one end, and a driven wheel at the other end, wherein a support frame is arranged at one end of the driven wheel close to the driving wheel, and the driving wheel is driven to rotate by a driving mechanism so that the crawler-type inductive adjustment mechanism moves forward;

[0006] A flange is fixedly arranged on the rotating shaft of the driving wheel, and the flange is connected to a short spline shaft. A rectangular hole is arranged at one end of the short spline shaft. The torsion sensor passes through the driven hub of the torsion damper and is inserted into the rectangular hole of the short spline shaft. The torsion sensor rotates with the rotation of the short spline shaft. The short spline shaft is connected to the driven hub through a spline.

[0007] The torsion damper is fixedly connected to the swing arm of the crawler-type sensing adjustment mechanism, and the swing arm is fixedly connected to the lateral extension line of the support frame. The other end of the torsion sensor is fixedly connected to the swing shaft. A transmission mechanism for driving the overall structure of the crawler track to be lifted or lowered is arranged at one end of the crawler-type sensing adjustment mechanism close to the driving wheel. A control system is also arranged on the crawler-type sensing adjustment mechanism. The control system is electrically connected to the torsion sensor and the transmission mechanism. When the torsion sensor measures a change in torque, the signal is transmitted to the control system to control the operation of the transmission mechanism.

[0008] Furthermore, the short spline shaft, the driven disc hub and the torsion sensor are connected as one body.

[0009] Furthermore, the transmission mechanism includes but is not limited to an electric motor and a worm gear reducer, and the rotation of the electric motor drives the entire crawler structure to lift or fall.

[0010] Furthermore, an encoder is provided at one end of the worm gear reducer, and the rotation of the motor is recorded by the encoder.

[0011] Furthermore, the worm gear reducer is arranged on the frame plate of the crawler-type induction adjustment mechanism.

[0012] Furthermore, the torsional damper includes a damper disc, a spring, a driven disc hub, and a driven disc rivet spacer.

[0013] Furthermore, tension wheels are arranged between the driving wheel and the driven wheel and on both sides of the support frame.

[0014] Furthermore, the driving mechanism is a pair of worm gear reducers or bevel gear transmission sets with axes perpendicular to each other.

[0015] The beneficial effects of the present invention are:

[0016] The crawler sensing adjustment mechanism provided by the present invention can automatically adjust the lifting and lowering of the crawler according to different road conditions, and is suitable for different road surfaces. In particular, the advantages of the present invention will be more obvious in the case of rugged and complex terrain. The crawler sensing adjustment mechanism is equipped with a torsion damper, which changes the rigid connection into a flexible connection, greatly reduces the impact of obstacles on the crawler, and plays a good buffering role.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] A crawler-type inductive adjustment mechanism, comprising an annular crawler 13, a driving wheel 11 arranged at one end in linkage with the crawler 13, and a driven wheel 15 at the other end, a support frame 16 is arranged at one end of the driven wheel 15 close to the driving wheel 11, and tensioning wheels 14 are arranged between the driving wheel 11 and the driven wheel 15 and on both sides of the support frame, the driving wheel 11 is driven to rotate by a driving mechanism 1 so that the crawler-type inductive adjustment mechanism moves forward, and the driving mechanism 1 is a pair of worm reducers or bevel gear transmission groups with axes perpendicular to each other;

[0025] A flange 10 is fixedly arranged at a coaxial position of the rotating shaft 12 of the driving wheel 11, and the flange 10 is connected to the short spline shaft 2. One end of the short spline shaft 2 is provided with a rectangular hole matched with the front end of the torsion sensor 4. The torsion sensor 4 passes through the driven hub 902 of the torsion damper 9 and is inserted into the rectangular hole of the short spline shaft 2. The torsion sensor 4 rotates with the rotation of the short spline shaft 2. The short spline shaft 2 is connected to the driven hub 902 through a spline.

[0026] The torsional damper 9 includes a damper disc 903, a spring 904, a driven disc hub 902, and a driven disc rivet spacer 901. The torsional damper 9 is fixedly connected to the swing arm 3 of the crawler-type inductive adjustment mechanism, and the swing arm 3 is fixedly connected to the support frame 16. The other end of the torsional sensor 4 is fixedly connected to the swing shaft 5. A transmission mechanism for driving the overall structure of the crawler to be lifted or lowered is arranged at the end of the crawler-type inductive adjustment mechanism close to the driving wheel 11. The transmission mechanism includes but is not limited to an electric motor 8 and a worm gear reducer 6. The rotation of the motor 8 drives the overall structure of the crawler to be lifted or lowered. An encoder 7 is arranged at one end of the worm gear reducer 6, and the rotation of the motor 8 is recorded by the encoder 7. The worm gear reducer 6 is arranged on the frame plate 17 of the crawler-type inductive adjustment mechanism, that is, the frame plate 17 is arranged at the end of the crawler-type inductive adjustment mechanism close to the driving wheel 11, and can be on the same side as the torsional sensor 4. The short spline shaft 2, the driven disc hub 902, and the torsional sensor 4 are connected as a whole. A control system is also provided on the crawler-type sensing adjustment mechanism, and the control system is electrically connected to the torsion sensor 4 and the transmission mechanism. As the driven hub 902 of the torsion damper rotates, the driven hub 902 is connected to the short spline shaft 2 and rotates together, and the short spline shaft 2 is connected to the torsion sensor 4 and rotates. The torsion sensor 4 measures the change in torque and transmits the signal to the control system. When the torque value reaches a certain position set in the software, the motor 8 starts to rotate to drive the entire crawler structure to lift or fall.

[0027] Working principle: When the track sensing adjustment mechanism encounters resistance during the forward movement, the swing arm 3 tilts upward. At this time, the intermediate spring 904 of the torsion damper is compressed along with the swing arm 3, playing a buffering role. When the intermediate spring 904 is compressed to a certain position, the torsion damper 9 becomes a whole. At this time, the driven hub 902, the short spline shaft 2, the torsion sensor 4, and the swing shaft 5 form a whole. The torsion sensor 4 measures the change in torque, and the control system sets the torque to a certain position so that the motor starts to rotate. The rotation of the motor 8 drives the track to lift or fall, and the encoder 7 at one end records the rotation of the motor 8. According to the measurement data of the torsion sensor, the control software decides whether the motor 8 stops or not to achieve the purpose of crossing the obstacle.
