Description

Straightening axis structure of the towing machine

The present invention relates to an axial joint structure in which the power carrier or the leveling unit can be horizontally or tilted to the ground when the towing machine is passing through a flat or uneven ground.

At present, before the cultivation in the farmland, it is necessary to carry out the soil preparation for the agricultural land. Early land preparation relied entirely on manpower or animal power, but its land preparation efficiency was too low, and it cost manpower and was not economically viable. Later, the use of power tools such as towing machines or traction machines for land preparation has not only saved manpower but also greatly improved efficiency. The towing machine is a mechanized power tool. It can be loaded with a variety of different land preparation tools at the rear to carry out different land preparation work, so as to quickly achieve the effect of loosening the soil and leveling the agricultural land.

Common towed machine structures, such as the new type M367572, "The screeding aid of the traction machine leveling device" announced by the Republic of China on November 1, 1998, reveals that it can improve the leveling effect of agricultural land. The screed auxiliary mechanism is provided with a flat structure on the leveling device of the traction machine, and the screed structure is provided with a plurality of pivot seats on the leveling device, and each pivot seat is provided with a rearward Extending the extension rods, and each of the extension rods is provided with a specific weight of the smoothing group. Through the above design, when the traction machine uses the leveling device to complete the soil preparation, the protruding soil blocks can be further smoothed by the smoothing structure. , and can improve the effect of the traction machine on the farmland.

However, once the traction locomotive body of the patent case passes through a pothole or a bulge on the ground, it will tilt with the pothole or the bulge, so the screed device mounted at the rear will also follow The traction machine body is tilted together. Therefore, if the leveling device is being turned to the ground, the leveling unit will be damaged or malfunction due to the tilting state, and the repair and replacement will be required, resulting in waste of time and money. Therefore, it is not ideal in use.

Similarly, there is a new patent No. M462503 “Connecting device for agricultural machinery and leveling device” announced by the Republic of China on October 1, 102. It is disclosed that the leveling unit includes two sides of a main leveler. a secondary screed that can be folded and flattened by a hydraulic cylinder, and the main screed is fixed at the lower end of the link seat pivoted at the outer end of the lift arm, and then the connection The upper end of the rod base is pivotally fixed to the main hydraulic cylinder connected to the carrier, and the inner end of the lifting arm is firstly fixed to one end of the shaft, and then the shaft is pivoted and fixed on the carrier. In the pivoting seat provided, the lifting arm can be rotated up and down in addition to being driven by the main hydraulic cylinder, and the shaft can be rotated as the center, and then the flattening unit can pressurize the uneven agricultural land. When the flattening unit has different heights and undulations on the left and right sides, resulting in the twisting phenomenon of the lifting arm, the free rotation ability of the shaft can be transmitted, so that the lifting arm can be twisted, so that the lifting arm and the vehicle can be avoided. The pivot joint is easily damaged.

The agricultural machine carrier of the patent case also has a slope when it passes through a pothole or a bulge, and the leveling unit mounted at the rear of the patent is tilted with the agricultural vehicle carrier when it is turned to the ground. The leveling unit is damaged by the impact and is damaged in the soil, so it is also not ideal for use.

Accordingly, in view of the fact that the current towing machine has the above disadvantages in use. Therefore, the present invention provides a leveling shaft structure of a towing machine, comprising a power carrier, and a first pivoting end; a fixing base is provided with a pivot rod, and the pivoting rod is provided with a second pivoting end. The pivoting is pivoted to the first pivoting end, the fixed seat pivotally swings relative to the power carrier, and a flattening unit is pivotally connected to the fixed seat.

The first pivoting end is a round shaft hole, and the second pivoting end is a round shaft that fits the round shaft hole.

The present invention further includes a correction unit, the correction unit is disposed on the power carrier, the correction unit is provided with two lugs, and the two lugs are respectively fixed on two sides of the pivot rod, and the two lugs are respectively respectively One of the adjusting rods is inserted into the upper and lower sides, and the other ends of the two adjusting rods are respectively coupled with a pushing member, and the two pushing members respectively drive the adjusting rods to move up and down, and the two adjusting rods are respectively disposed on the two lugs A first spring and a second spring are respectively disposed on the upper and lower sides, and one of the two first springs and the second springs are respectively pressed against the two lugs.

The two pushing members are respectively driven by a power source to drive the two adjusting rods to move up and down.

The two power sources may be respectively a hydraulic cylinder and disposed on the rear side of the power carrier.

The two sides of the power carrier are respectively provided with a sliding portion, and the two ends of the pivoting rod are respectively provided with a pulley, and the two pulleys are respectively slidably contacted with respect to the two sliding portions, thereby having a supporting function and reducing frictional resistance.

The first pivoting end is disposed on a rear side of the power carrier.

The above technical features have the following advantages:

1. When the power carrier is tilted through the uneven ground, the leveling unit can still maintain the horizontal state, so as not to be damaged by the impact and the ground.

2. When the power carrier passes through the flat ground, and the leveling unit passes through the uneven ground, the power carrier can still maintain the horizontal state, and the leveling unit can be tilted with the uneven ground to avoid As the ground tilts, it hits the soil and is damaged.

3. The two ends of the pivot rod are respectively provided with a pulley, and the two pulleys can respectively slide with respect to the two sliding portions, so as to adjust the tilting angle of the leveling unit, it can have a supporting effect and reduce friction. resistance.
