CN203597082U - Full-feeding conveying trough of combined harvester - Google Patents

Abstract

The utility model provides a full-feeding conveying trough of a combine harvester. The full-feeding conveying trough of the combine harvester is composed of a conveying trough box body, connection lugs, tension springs, arc troughs, a driven wheel, a rolling bearing, rocker shafts, a rocker shaft supporting frame, a conveying chain, a conveying chain supporting plate, a supporting plate supporting frame, a grass scraping plate, a drive wheel and a drive wheel supporting frame. The full-feeding conveying trough of the combine harvester is characterized in that two lateral box plates, at the driven wheel end, of the conveying trough box body are symmetrically provided with the arc troughs and provided with the connection lugs in a welded mode. The rocker shafts are installed in the arc troughs and can move along the arc troughs. An inner ring and an outer ring of the rolling bearing are matched with the rocker shafts and the driven wheel respectively. The conveying chain is matched with the driven wheel and the drive wheel and the grass scraping plate is arranged on the conveying chain. The tension springs are connected with the rocker shafts and the connection lugs. When the combine harvester works, the rocker shafts move along the arc troughs as the feeding amount varies so as to change a gap between the grass scraping plate and the bottom of the conveying trough. Crops are reliably conveyed to a threshing cylinder. The full-feeding conveying trough of the combine harvester is simple in structure, low in cost, reliable in performance and convenient to use and maintain.

Description

A kind of all feeding-in combine delivery chute

Technical field

The utility model relates to a kind of full-feeding combine harvester delivery chute, and especially a kind of full-feeding combine harvester delivery chute that can prevent that crop from stopping up, belongs to agricultural mechanical field.

Background technology

Agricultural production mechanization is not only beneficial to be robbed farming season, the season of catching up with, and more contributes to short volume increase, protects good harvest.Along with improving constantly of China's agricultural production mechanization level, oneself reaches 87.8% national wheat machine receipts level, and rice machine receipts level reaches 60%.But all feeding-in combine, after crop is cut, is transferred in threshing cylinder process by the ceding of Taiwan, traditional mechanical mode of movement is often because of feed quantity shakiness, and causes delivery chute plugging fault frequently to occur.Delivery chute plugging fault is got rid of, consuming time, effort.The frequent generation of fault, not only reduces machinery operation efficiency, reduces tractor driver's income, also can cause grain loss.Therefore, design a kind of block-resistant type delivery chute very necessary.

Utility model content

The problems referred to above that exist in process of production for all feeding-in combine, the purpose of this utility model is to provide a kind of all feeding-in combine delivery chute that prevents crop obstruction function that has.

The utility model is achieved through the following technical solutions:

A kind of all feeding-in combine delivery chute, by delivery chute casing 1, engaging lug 2, back-moving spring 3, arc groove 4, driven pulley 5, rolling bearing 6, swinging shaft 7, swinging shaft support 8, chain 9, chain gripper shoe 10, gripper shoe support 11, scrape standing grain plate 12, driving wheel support 13, driving wheel 14 and form; It is characterized in that: described delivery chute casing,, respectively there are one section of arc-shaped slot and an engaging lug in symmetric position place on two side box plates of driven pulley end; Described swinging shaft is installed in two Symmetrical Circular Arc grooves, can in arc groove, move; Described swinging shaft coordinates with the inner ring of rolling bearing, and the outer ring of rolling bearing coordinates with the endoporus of driven pulley; Described chain coordinates with driven pulley and driving wheel, is equipped with and scrapes standing grain plate on chain; Described back-moving spring one end is connected on swinging shaft, and the other end is connected on engaging lug;

The beneficial effects of the utility model are: a kind of all feeding-in combine delivery chute, has the advantages such as simple in structure, with low cost, elastic block-proof, dependable performance.

Accompanying drawing explanation

Accompanying drawing is a kind of all feeding-in combine delivery chute structural representation.

Specific embodiments

Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing, the utility model is further described.

As shown in the figure, a kind of all feeding-in combine delivery chute, by delivery chute casing 1, engaging lug 2, back-moving spring 3, arc groove 4, driven pulley 5, rolling bearing 6, swinging shaft 7, swinging shaft support 8, chain 9, chain gripper shoe 10, gripper shoe support 11, scrape standing grain plate 12, driving wheel support 13, driving wheel 14 and form, it is characterized in that: described delivery chute casing, symmetric position place on two side box plates of driven pulley end, respectively have one section of arc-shaped slot and be welded with an engaging lug, described swinging shaft is installed in the arc groove of two symmetries, can in arc groove, move, described swinging shaft coordinates with the inner ring of rolling bearing, the outer ring of rolling bearing coordinates with the endoporus of driven pulley, described chain coordinates with driven pulley and driving wheel, on chain, be equipped with and scrape standing grain plate, described back-moving spring one end is connected on swinging shaft, the other end is connected on engaging lug, when operation, driving wheel drives chain to move, chain takes driven pulley to and rotates, crop is pushed at the standing grain plate of scraping being installed on chain, under draw, at the bottom of delivery chute, transferred to threshing cylinder, in this process, if feeding crop amount is excessive, crop extruding swinging shaft, make it along arc groove move upward (back-moving spring is stretched), the gap of scraping at the bottom of standing grain plate and delivery chute increases, in the time that feed quantity diminishes, under the effect of spring tension, swinging shaft moves downward along arc groove, the gap of scraping at the bottom of standing grain plate and delivery chute reduces, and so forth, scrape the gap at the bottom of standing grain plate and delivery chute, under the acting in conjunction of spring and crop, size with feeding crop amount changes, thereby guarantee that crop is reliably transferred to threshing cylinder.

Above-described embodiment does not limit the utility model in any form, all take to be equal to replace or technical scheme that equivalent transformation obtains, all drop in protection domain of the present utility model.
