Description

Rice bundling machine

Technical Field

The invention relates to the technical field of rice equipment, in particular to a rice bundling machine.

Background

The rice bundling machine belongs to a machine tool of a rice harvesting machine, is key equipment of a rice segmented harvesting process, belongs to small and medium-sized agricultural machines, is low in price, and meets the requirements of domestic agricultural cooperative societies and individual farmers.

The rice harvesting machine goes through the difficult development process from simple to complex, low-grade to high-grade and laggard to advanced, the early mechanized harvesting mode of rice is to harvest directly after drying up and frosting, and the defects of high water content of rice, high drying cost, high pressure of a sunning ground, danger of being covered by snow and the like exist. In the whole-course mechanization of paddy fields, the rice harvesting problem is the key influencing the high yield and harvest of rice. The harvest loss is large, the grain moisture is large, the quality is reduced, the benefit is greatly reduced, and the bottleneck for improving the quality, increasing the yield and increasing the efficiency of the rice is formed. The current mechanized harvesting technology of rice is mechanized and segmented harvesting of rice. The rice is harvested in sections, so that the effective harvesting period can be prolonged, the rice harvesting progress is accelerated, the rice moisture is reduced, the quality is improved, the safe storage is realized, the rice selling price is improved, the benefit is increased, and the high yield and the high harvest of the rice are ensured. The technology is accepted by rice growers and widely applied to rice harvest. The rice sectional harvesting matching machine has the following advantages compared with a combined harvester: firstly, the cost is low, and farmers can bear the cost; secondly, the cut bamboo leaves are naturally aired without drying equipment, so that the production investment is saved; thirdly, the straws can be returned to the field or recycled; and fourthly, the sectional harvesting machine can be used as a supplementary machine type of the combine harvester.

The function of the rice bundler is to bundle rice (including ears), put the rice in the field for natural drying, then use a half-feeding thresher to thresh when the water content of the rice is reduced to about 15%, and bundle the rice at the same time. The bundling rope is bundled at the rhizome part.

The original paddy rice bander adopts the C-shaped knotter, has low bundling rate, has the phenomena of loose knot and easy tripping, and simultaneously has the phenomenon that the parts of the knotter are easy to wear. The enterprise improves the C-type knotter into a D-type knotter for making a dead knot, the tripping fault is solved, but the adaptability of the binding rope is poor, and the bundling rate of the thin rope, the hemp rope and the regenerated rope is not high and is lower than 90 percent; when the machine runs for a period of time, the knotter baling rate is reduced, loose bales are generated continuously, and farmers need to bundle again, thus wasting time and labor. Meanwhile, the phenomenon that the grass kicking mechanism is broken and the front and the rear grass bundles are adhered to each other occurs; influence the bale shape, fall the ear of grain volume greatly, and the sprocket setting of current bundling machine is in bundling machine both sides, and the component is more, and it is more troublesome to equip.

The transmission movable handle 607 rotates to drive the long link 610 and the short link 613 to drive the rope feeding needle shaft 605 to rotate, the rope feeding needle 601 is fixed with the rope feeding needle shaft 605, the rope feeding needle 601 rotates along the rope feeding needle shaft 605, the rope feeding needle 601 carries the binding rope, and the rope feeding needle 601 sends the binding rope to the knotter 707 to be knotted.

The knotting fixing handle 606 is fixed with the knotter mounting shaft 701, when the signal sending fixing handle 606 rotates, the knotter mounting shaft 701 also rotates, the thread shifting cam 7601 rotates along with the knotter fixing shaft 701, the thread shifting cam 7601 drives the roller 7602 to move in a thread shifting cam 7601 groove, the roller 7602 drives the thread shifting rod 7603 to swing so as to drive the thread shifting push rod 7605 to do reciprocating motion, and the thread shifting push rod 7605 drives the thread shifting plate 7606 to do reciprocating motion.

The knotting attachment handle 606 is fixed to the knotter mounting shaft 701, the knotter toothed disc 7704 rotates with the knotter mounting shaft 701, and the knotter toothed disc 7704 drives the olecranon 7705 and the worm 7702 to rotate. When the rope feeding needle 601 sends the bundling rope to the knotter 707, the worm 7702 drives the rope clamp 7701 to clamp the bundling rope, the wire poking plate 7606 pokes the bundling rope to a certain angle, and the olecranon 7705 rotates to knot; when the knotting is finished, the thread pulling plate 7606 returns to the thread pulling-out-free state, and the thread feeding needle 601 also exits from the knotter 707, so that the knotting operation is finished. The kicker needle 714 kicks the knotted rice bundle out of the discharge plate 907 to complete the knotting action of the rice bundle.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, various changes or modifications may be made by the patentees within the scope of the appended claims, and within the scope of the invention, as long as they do not exceed the scope of the invention described in the claims.
