Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a baler traction device with a gear box. Background Art

[0002] A baler is a machine used to bundle grass. It has the following characteristics: a wide range of applications, and can be used to pick up and bundle straw, wheat straw, cotton stalks, corn stalks, rape stalks, peanut vines, bean stalks and other straw and forage grass; it has many supporting functions, and can be picked up and bundled directly, or cut first and then picked up and bundled, or crushed first and then bundled. A round grass baler is a type of baler. Most of the existing round grass balers are started and moved by tractors. The connecting traction device between the round grass baler and the tractor is one of the safety functions of the round grass baler. When the baler is driven, the impact on the connection part is very large, which can easily cause the connection part to loosen and disconnect. However, the above two patents do not solve this problem, and the connection and installation of the traction device of the above comparative patents are more troublesome. Therefore, we propose a round grass baler hooking traction device.

[0003] After searching, the published announcement number CN109429599B discloses a round grass baler hanging and traction device, including a baler body, a driving vehicle body, a driving vehicle traction block, a baler traction block, a first steering block, a movable connecting block, a buffer spring, a connecting rod, a first pin, a pin slide groove, a rotating groove, a rotating chuck, a second steering block, a third steering block, a steering connecting block and an elastic groove. A second steering block is fixed at the rear of the driving vehicle body, and the second steering block is rotatably connected to the driving vehicle traction block. This is a round grass baler hanging and traction device.

[0004] However, when the baler is working, the gearbox responsible for transmitting power is under high load operation. In the absence of a buffer carrier, vibration and noise increase, wear intensifies, life is shortened, and transmission efficiency decreases. In severe cases, it can cause rigid fracture of the internal gears. Moreover, the baling operation of the baler is in complex terrain, especially when operating on hills and multi-ridge fields. Since the currently used traction mechanism has insufficient degrees of freedom, terrain changes cause deformation and vibration of the traction mechanism, which will inevitably aggravate the vibration of the operating equipment and affect power transmission. In addition, the universal joint used to transmit power will easily generate more heat and reduce its service life due to friction and the interaction of internal parts under conditions of high speed, high load or long-term continuous operation. Summary of the invention

When driving on an uneven road and encountering a gully, the traction frame or the transmission shaft will not be damaged due to torsion. Brief Description of the Drawings

A friction block 7 is fixedly connected to the end of the blade plate 6.Since the rotating shaft 36 is not coaxial with the second output shaft 211, when the rotating shaft 36 rotates, the lower surface of the rotating shaft 36 will contact the friction block 7, causing the rotating ring 5 to rotate. When the blade 6 rotates, it will drive the air flow inside the shielding cylinder 4, assisting in dissipating heat from the universal joint 2111. The friction block 7 on the upper blade 6 does not contact the rotating shaft 36, which can assist in dissipating heat at the universal joint 2111 and has a protective effect, blocking to prevent the problem of straw entanglement.

Through the round hole 141 provided on the horizontal traction frame 14, it is convenient for the staff to connect the horizontal traction frame 14 with the corresponding equipment. At the same time, through the anti - slip sleeve 142 provided in the round hole 141, the friction between the devices is increased, thereby improving the overall stability of the device. The swing connecting plate 12 provided on the bottom plate 1 enables the special double - joint gearbox 16 to control the horizontal rotation of the device when using the device. Through the vertical plate 33 provided on the long plate 31 and the sliding plate 35 slidably arranged on the vertical plate 33, when the staff controls the movement of the sliding plate 35, the cleaning ring 351 fixedly arranged on the sliding plate 35 can clean the impurities on the outer surface of the rotating shaft 36, ensuring the cleanliness of the outer surface of the rotating shaft 36. The reciprocating lead screw 342 provided between the two brackets 34 enables the sliding plate 35 threadedly connected to it to move when the reciprocating lead screw 342 rotates, realizing the cleaning of the outer surface of the rotating shaft 36. Through the pulley 343 provided between the rotating shaft 36 and the reciprocating lead screw 342, when the rotating shaft 36 rotates, the pulley 343 fixed on its outer peripheral surface rotates, and drives the pulley 343 on the reciprocating lead screw 342 to rotate through the belt.
