Description
Technical Field
The utility model belongs to a device for stabilizing the speed of a drip irrigation tape roll.
Background
At present, the drip irrigation technology is widely used in modern agriculture, and the drip irrigation of plants is realized by drip irrigation tapes (or pipes) laid on the ground. When laying the drip irrigation zone, lay the machines and put at the tractor rear portion, the machines and tools of laying the drip irrigation zone all are served at two axles that will leave factory the package card of drip irrigation zone on laying machines rear portion frame, and the drip irrigation zone book can the free rotation on two axles are served. When the tractor moves forward, the traction force of the drip irrigation tape which is already laid on the ground drives the drip irrigation tape roll to rotate, and the drip irrigation tape is released section by section and laid on the ground, so that the laying work is completed. During operation, when the tractor rotates from a high speed to a low speed, the drip irrigation tape roll pulled by the ground drip irrigation tape rotates rapidly to release the drip irrigation tape under the action of the inertia, so that the drip irrigation tape is bent or stacked on the ground.
Disclosure of Invention
The utility model aims at designing a device of stable drip irrigation tape roll speed can apply a damping for the drip irrigation tape roll, eliminates the change of the drip irrigation tape release amount that unit speed fluctuation leads to, improves the shop of drip irrigation tape and applies the quality, still has simple structure, convenient to use and excellent in use effect's advantage.
For this reason, the utility model discloses a frame and tapered roller bearing, the hole that link up is established at the middle part of roll joint, the one end welding of pivot is in the frame at laying machines rear portion, the other end of pivot is from the rear portion of roll joint and wears into the hole, be located the inner circle of fixed a pair of tapered roller bearing in the pivot in hole rear portion, be equipped with the clamping ring in the pivot of a pair of tapered roller bearing's outer lane front end, the rear end of clamping ring is held with the outer lane front end top of the tapered roller bearing of corresponding portion, the cover is equipped with the pressure spring in the pivot of clamping ring front end, be equipped with the sleeve between the periphery wall of pressure spring and the hole internal perisporium of corresponding portion, the rear end top of pressure spring is on the preceding terminal surface of clamping ring, the spiral shell is equipped with a pair of round.
The central axis of the roll joint and the central axis of the inner hole are the same straight line. The front part of the roll joint is in a circular truncated cone shape. The structure achieves the purpose of the utility model.
The utility model discloses can apply a damping for the drip irrigation tape roll, eliminate the change of the drip irrigation tape release amount that unit speed fluctuation leads to, improve the shop of drip irrigation tape and apply the quality, still have simple structure, convenient to use and excellent in use effect's advantage. The utility model discloses eliminated because the speed of traveling of tractor appears undulantly, and made the release amount of drip irrigation zone appear undulantly, and lead to the drip irrigation zone at ground curve or accumulational not enough, the drip irrigation zone that the drip irrigation zone coiled up in the frame promptly only receives and has laid under the certain pulling force of subaerial drip irrigation zone, just can derive, has saved the waste of drip irrigation zone, has improved the tape laying quality.

Detailed Description
As shown in figure 1, the device for stabilizing the speed of the drip irrigation tape coil comprises a rack and a tapered roller bearing 1, wherein a through inner hole is formed in the middle of a coil joint 8, and the central axis of the coil joint and the central axis of the inner hole are the same straight line. The front part of the roll joint is in a round table shape so as to facilitate the drip irrigation tape roll 4 to be sleeved on the joint.
One end of a rotating shaft 9 is welded on a machine frame 10 at the rear part of the laying machine, and the other end of the rotating shaft penetrates into the inner hole from the rear part of the rolling joint. The inner rings of the pair of tapered roller bearings are fixed on the rotating shaft in the rear part of the inner hole, the pair of tapered roller bearings support the rolling joint, the rolling joint can freely rotate around the rotating shaft, and the drip irrigation tape roll is sleeved on the rolling joint, so that the drip irrigation tape roll also freely rotates around the rotating shaft.
And a compression ring 7 is arranged on a rotating shaft at the front end of the outer ring of the pair of tapered roller bearings, and the rear end of the compression ring is propped against the front end of the outer ring of the tapered roller bearing at the corresponding part. The rotating shaft at the front end of the compression ring is sleeved with a compression spring 2, and a sleeve 6 is arranged between the outer peripheral wall of the compression spring and the inner peripheral wall of the inner hole of the corresponding part. The rear end of the pressure spring is pressed against the front end face of the compression ring, a pair of round nuts 5 are screwed on a rotating shaft at the front end of the pressure spring, and the tapered roller bearing is pressed on the step of the rotating shaft by the pair of round nuts through the pressure spring. Obviously, when the tightness pressure of the pressure spring is relatively adjusted by using a pair of round nuts, the compression degree between the compression ring and the outer ring of the tapered roller bearing can be increased, namely, the friction force is increased, and the damping is increased. That is, the pressure between the rolling bodies and the raceways of the tapered roller bearing is changed by adjusting the tightness of the pressure spring, so that the rolling friction force is changed. The tighter the compression spring is compressed, the greater the friction force.
The front end face of the roll joint is provided with a gland 3 for sealing the front end of the sleeve in the inner hole, the middle part of the gland is provided with a hole, the gland can be fixed on the front end face of the roll joint through a screw, and a bearing is arranged between the middle part of the gland and the rotating shaft of the corresponding part, so that the effect is optimal.
During the use, install one set respectively in the frame of two axle departments department of the former installation drip irrigation tape roll of current laying machines the utility model discloses a device, the both ends middle part of drip irrigation tape roll cup joints respectively on two book joints. The pair of round nuts is twisted to adjust the tightness of the pressure spring and the torque required by rotating the drip irrigation tape roll. Namely: after cup jointing the drip irrigation tape roll and rolling up the connector at two, draw out a plurality of length with the drip irrigation tape from the drip irrigation tape roll manual work again and lay on subaerially, start the drip irrigation tape laying machine, if find the drip irrigation tape can not follow the drip irrigation tape roll and normally release and lead to the laying machine to have the trend of dragging the drip irrigation tape forward, then counter-clockwise turning is a pair of round nut, reduces the pressure of pressure spring to reduce this rotation frictional force to tapered roller bearing. And conversely, the pair of round nuts are rotated clockwise, and the pressure of the pressure spring is increased, so that the rotating friction force of the pair of tapered roller bearings is increased until the release speed of the drip irrigation tape meets the laying requirement.
In a word, the utility model discloses can apply a damping for the drip irrigation tape roll, eliminate the change of the drip irrigation tape release amount that unit velocity fluctuation leads to, improve the shop of drip irrigation tape and apply the quality, still have simple structure, convenient to use and excellent in use effect's advantage.
