Abstract
The utility model provides an elastic conveying device and relates to agricultural machinery. The elastic conveying device comprises a conveying mechanism I arranged along the horizontal direction, a conveying mechanism II and a group of spring self-regulation devices; each conveying mechanism comprises conveying chains, conveying wheels and a tensioning mechanism, wherein a pair of clamp teeth is arranged on each section of the chains; the conveying mechanism II is arranged right above the conveying mechanism I; the conveying chains I and the conveying chains II are close to each other, and the tooth tips of the clamping teeth on the conveying chains I and II are opposite; each spring self-regulation device comprises a pressure plate and a compression spring with one end propped against the pressure plate; the pressure plates are contacted with the inner side of the chain on the lower side of the conveying mechanism II; in the nonworking state, the compression springs are unstrained, and the lengths of the pressure plates are equal to the distance between straws during feeding; and the pressure plates in the group of spring self-regulation devices are arranged in sequence, and the maximum value of the total length of the pressure plates can not influence rotation of the conveying wheels II. The elastic conveying device can regulate the size of a conveying port according to the thickness of each straw so as to avoid the circumstance of extreme tightness or looseness of clamping.
Description
Technical field
The utility model relates to farm machinery, and particularly a kind of green soybean that is used for is plucked the mechanical conveying plant of pod.
Background technology
The conveying plant that existing green soybean is plucked pod machinery all adopts the chain drive feeding.Described in ZL200920039340.X, conveying plant mainly is made up of carrier chain mechanism, load spring and clamping pressing plate.During use, the sprocket on the carrier chain blocks straw, and load spring and clamping pressing plate are pressed on straw on the carrier chain from top, and carrier chain drives straw and moves.This transporting pattern is feasible, but in actual production process, we find to exist drawback.The green soybean straw diameter of nature differs, and crosses when thick when the straw diameter, and this conveying plant can cause chain clamping tension, and then causes the feeding transmission to be interrupted; Otherwise when the straw diameter was meticulous, this conveying plant can cause the chain clamping loose excessively, and straw can fly out along with the falling power of nip rolls when causing taking off pod, influences operation effectiveness, has reduced threshing performance.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, provides a kind of in operation process, can regulate the elasticity conveying plant of transmission mouth according to the straw size automatically.
The technical solution of the utility model is: a kind of elasticity conveying plant; It comprises the conveying mechanism I that along continuous straight runs is provided with; On the chain of conveying mechanism I; Every pitch chain bar all has a pair of clamping tooth, it is characterized in that: it at least also comprises conveying mechanism II and one group of spring self-checking device; Said conveying mechanism II comprises the carrier chain II at least, with the supporting delivery wheel II of carrier chain II be used for the strainer II of tensioning carrier chain II; Every joint carrier chain II all has a pair of clamping tooth; The conveying mechanism II be horizontally set on the conveying mechanism I directly over; The downside chain of conveying mechanism II is close to the upside chain of conveying mechanism I, and clamping tooth crown is relative on carrier chain I of pressing close to each other and the carrier chain II; Said each spring self-checking device is become with the compression spring set that an end withstands pressing plate by pressing plate, side contacts in the downside chain of pressing plate and conveying mechanism II, and the compression spring does not stress the distance the when length of every block pressur plate equals feeding between straw during off working state; Every block pressur plate is arranged in order in one group of spring self-checking device, and total length is advisable with the maximum length that does not influence the rotation of delivery wheel II.
Said spring self-checking device is by pressing plate, and an end is fixed on the back shaft on the pressing plate, and the compression spring set that is enclosed within on the back shaft becomes.
When the utility model uses; Straw is clamped between carrier chain I and the carrier chain II, because the length of the pressing plate distance between straw when equaling feeding, so each spring self-checking device is only done to a straw and compressed; Can regulate transmission mouthful size automatically according to the straw size; Can not occur the too tight or too loose situation of clamping again, operation effectiveness is good, has improved threshing performance.
