Abstract

The utility model discloses a peanut reaping machine, which includes a dig utensil, a stander, a driving part, a tube-style rotating sift, a nick-style picking sift and a transport device. The utility model is characterized in that the peanut fruit and the earth are scoop out together by a plough spade when harvesting peanuts, the utility model is lifted to a first raising chain, then is transported to a second raising chain in the sift. The second raising chain transports the peanut fruit to a transverse transport chain and then throws the peanut fruit to the right ground. The earth and the fruit fall in the sift, the earth is sieved by sieving, and the peanut fruits are gathered in a fruit-gathering slot. The utility model has new structure and can harvest nearly all peanut fruits, only less than 0.1 percent of fruit is remained in the field.

Description

Harvester for peanut

The utility model relates to a kind of agricultural machinery product, particularly relates to a kind of harvester for peanut.

In harvesting peanut season, people generally adopt dual mode to carry out operation at present, and a kind of is with traditional artificial work, and another kind is to adopt mechanical harvest.Artificial results peanut efficient is very low and the amount of labour is big, and the breakage of peanut, fruit drop rate are also higher.In the vast peanut cultivation zone of China, have some areas to adopt mechanical harvest now, this has just improved the results efficient of peanut on certain Cheng Du.Chinese patent CN2332158Y discloses a kind of " efficient peanut reaping machine " comprises the roller that buries, plough, rotary cutter, sieve curtain, bar shaped excavation cutter and transmission mechanism.It can improve results speed effectively, can prevent the peanut fragmentation, and the peanut seedling fruit is separated with earth, reaches and gathers in the crops effect preferably.But this efficient peanut reaping machine can not and be concentrated peanut shedding results.Because peanut is uneven flowering stage, so fruit has ripe sooner or later other on the homophyletic peanut straw.During results, the peanut pin of ripen in advance easily goes rotten, and this stays into underground with regard to causing part fruit and seedling to break away from, and meets rainy weather more very, and fruit seedling disengaging rate can reach more than 40%.Behind this machine operation, still need a large amount of artificial multiple receipts, make production efficiency be subjected to very big influence.

The purpose of this utility model is to overcome the deficiency of prior art, and providing a kind of can not only separate the peanut seedling fruit with earth, and can more effectively gather in the crops the peanut shedding totally and focus on the harvester for peanut in the fruit collecting groove on the machine.Thereby improve results efficient.

The purpose of this utility model is by providing a kind of harvester for peanut with following structure to realize, this harvester for peanut comprises: delver, frame, transmission mechanism, cylinder type strip-eye rotating screen, gap type pick cribellum and conveying plant, described delver is installed between the oblique fork of frame front both sides, comprises plough shovel, plough shovel frame, the first elevator chain and sprocket.Sprocket wheel is positioned at delver left side rear end lower, links by the minor sprocket of chain with second right-hand member that is installed in the frame front left side.Tension pulley block is arranged on the chain, link with steel wire rope and tractor lift arm, described frame front end is provided with pulls crossbeam and partly is connected with tractor-drawn, and the both sides, middle part are equipped with universal wheel.Described transmission mechanism: be equipped with first transverse axis and a bevel gear box at the frame front upper part, this axle crosses bevel gear box, and this case is installed in the first transverse axis right side.First transverse axis left side is equipped with minor sprocket, link with chain and second hinge wheel that is installed in the frame left side, the first transverse axis right side is equipped with bevel gear, it is on bevel gear box the right, with the 3rd axial cone gear interlock mutually that is installed in the frame upper right quarter, there are splined shaft and the line shaft that is installed in right side, tractor rear portion to link on the bevel gear box.

Described cylinder type strip-eye rotating screen is installed in the frame, above the gear ring and the interlock mutually of the 3rd shaft gear at two ends, two pulleys that four pulleys of the frame lower of being installed in arranged and be installed in the frame upper left quarter support.Described gap type picks cribellum, is installed in the upper rack left side, and the gear at two ends and the interlock mutually of cylinder type strip-eye rotating screen gear ring pick the support above the cribellum notch alignment cylinder type strip-eye rotating screen, stick in the sieve.Described conveying plant, comprise first elevating chain, second elevating chain and transversal chain conveyor, first elevating chain is installed on the delver, second elevating chain is installed in the cylinder type strip-eye rotating screen, front end links with the slip wheel shaft that is arranged on above the frame front column, the rear end links with the 5th sprocket wheel that is installed in the frame rear portion, transversal chain conveyor is installed in the frame rear portion, link with the 6th of lower left quarter, right and slip wheel shaft links, frame rear end top is provided with the 4th, is equipped with a gear, a bevel gear and a sprocket wheel on the axle.Gear and the interlock mutually of cylinder type strip-eye rotating screen rear end gear ring, bevel gear and the 5th axial cone gear interlock mutually, sprocket wheel and the 6th sprocket wheel join with chain, and the transversal chain conveyor upper stand is provided with oblique blend stop, and the bottom is equipped with fruit collecting groove.

The utility model compared with prior art has following advantage: owing on the anterior delver of harvester for peanut first elevating chain is installed, dark 11-the 13cm in plough shovel plough ground of front end during operation, peanut seedling fruit and earth have together been dug, risen on first elevating chain along the shovel face.Because this elevating chain chain seam is the same wide with the cylinder type strip-eye rotating screen seam, leak and not fall once the fruit that breaks away from peanut seedling, can only miss a small amount of earth, with being transported to back to back second elevating chain, second elevating chain chain seam broad, seam is apart from being 12cm, and it can only take away the peanut seedling fruit, and delivers to transversal chain conveyor and throw to the right on the ground.Shedding and earth fall in the sieve, and sieve rotates and to go soil, peanut to roll in the fruit collecting groove, gather in the crops peanut like this and can reach basically that Every grain should be sent to the granary.This machine per hour working area can reach more than 2.2 mu.

In addition then, this machine also has unexpected excellent results, and it can sift out soil insect grub and underground malignant weed root during operation, and this has just suppressed the growth of deriving of soil insect and malignant weed on certain Cheng Du.
