Abstract

The invention relates to a binding mechanism of a round-binding pick-up binder, belonging to the field of agricultural machinery. A first drive roll and a second drive roll are sequentially assembled in a rear binding room; one ends of a first swing arm and a second swing arm are respectively articulated with the centers of the first drive roll and the second drive roll, and the other ends of the first swing arm and the second swing arm are respectively provided with a first loose roll and a second loose roll through hinges; first springs are arranged on the first swing arm and the rear binding room; second springs are arranged on the second swing arm and the rear binding room; grass rolling belts are respectively sleeved with the first drive roll and the first loose roll and the second drive roll and the second loose roll; a third drive roll is arranged in a front binding room; both ends of a third swing arm are respectively articulated with the third drive roll and a third loose roll; and third springs are connected with the third swing arm and the front binding room. The binding mechanism of the round-binding pick-up binder has the advantages of novel and reasonable design, smooth operation process, uniform and firm binding density, good quality, reliable operation, less failure and high production efficiency.

Description

Binding mechanism of round-binding pick-up binder

Technical field

The invention belongs to agricultural machinery, relate generally to the operating assembly on herbage and the straw picking up and bundling facility.

Background technology

Circle bundle picking up and bundling machine is to use comparatively general a kind ofly with fodder grass with the forage crop straw is picked up and break into the work tool of circular bale and straw bundle synchronously with machine during current farming and animal husbandry is produced, and has played positive role in farming and animal husbandry is produced.But, because the defective on traditional circle bundle picking up and bundling machine structural design, pick up feeding and unidimensional structures such as volume grass steel rider assembly such as only adopting single pickup with performance, herbage or straw easily take place pick up the clogging that very easily has some setbacks in bundling house's grass bar porch generation feeding when feeding, the feeding difficulty, the technical matters that the bundling quality descends.For addressing the above problem, applicant had once been developed a kind of circle bundle picking up and bundling machine of new construction, and transaction capabilities improves and improves.Yet owing to adopt careless bar to feed single roller feeding structure, feeding is still apparent during operation has some setbacks, and operating efficiency is low.In addition, the volume grass steel rider that is configured in the forward and backward bundling house is fixed in same big outside dimension position, and not removable and adjusting changes, the whole tight ness rating of its bundling is descended, portion and outside tight ness rating are inconsistent in the bale, and bundling is second-rate, and bundling is looser.

Summary of the invention

Purpose of the present invention is exactly the problem that exists at above-mentioned prior art, design provides a kind of binding mechanism of round-binding pick-up binder of new construction, reaches to make things convenient for forage grass and straw to pick up the feeding bundling, avoid feeding obstructions, reduce the operation fault, improve the purpose that circle is tied bundling quality and operating efficiency.

Basic design of the present invention is, binding mechanism of round-binding pick-up binder comprises the bundling cup, chamber behind the bundling, the elastic claw type pickup, hydraulic jack and bundling send rope mechanism, in the bundling cup, be positioned at careless bar inlet position last volume grass steel rider is installed, top, indoor behind the equipped bundling of the careless steel rider of last volume, indoor behind bundling, last volume grass steel rider with on position configuration installation first driven roller and second driven roller successively rotationally between the careless steel rider of volume, first swing arm, one end is connected with the second driven roller center hinge with the first driven roller center respectively with second swing arm, one end, on the first swing arm other end and the second swing arm other end, be hinged respectively first loose roll and second loose roll are installed, the two ends of first spring are connected with chamber behind the bundling with first swing arm respectively, the two ends of second spring are connected with chamber behind the bundling with second swing arm respectively, on volume turf band is set between first driven roller and first loose roll and between second driven roller and second loose roll; In the bundling cup, above being positioned at last volume grass steel rider side, be rotatably mounted the 3rd driven roller, the 3rd swing arm one end is connected with the 3rd driven roller center hinge, be hinged on the 3rd swing arm other end the 3rd loose roll is installed, the two ends of the 3rd spring are connected on the 3rd swing arm and the bundling cup.Below bundling cup grass bar inlet, the configuration of elastic claw type pickup back side top installs the feeding lower roll, the 4th swing arm one end is hinged on the pleasure boat axle, hinge dress feeding top roll on the other end of the 4th swing arm, this feeding top roll is positioned at feeding lower roll top, and cooperatively interact, the 4th both ends of the spring is connected with the bundling cup with the 4th swing arm respectively, and backplate is configured in feeding top roll sidepiece.

Structural design of the present invention is new reasonable, and operation process is smooth and easy, and volume encircling density is evenly firm, and quality is good, and operation is reliable, and fault is few, the production efficiency height.
