Abstract

The invention provides a push-pull cutting type asparagus harvester which comprises a handle, a spring, a draw bar, a fixing rack, a holder, a rocking bar and a blade, wherein the handle and the fixing rack are fixed by a nut; the fixing rack and the holder are fixed by a screw and the nut; the upper end of the rocking bar is connected with the holder by a hinge pin; the handle is provided with an upper locating plate and a lower locating plate; the spring is arranged between the two locating plates; the pull plate of the draw bar is positioned between the lower locating plate and the spring; the lower end of the draw bar is connected with the middle of the rocking bar via a hinge pin; the blade is fixed on the lower end of the rocking bar by a hinge pin; the draw bar drags the blade on the rocking bar to cut off asparagus stems on the rocking bar; and then, the spring causes the blade to reset by virtue of the draw bar and the rocking bar. According to the push-pull cutting type asparagus harvester, the asparagus stems can be cut off underground, and the asparagus can be pulled out of the ground. The repeated harvesting action of stooping and straightening the waist when an operator harvests the asparagus can be avoided, the asparagus harvesting program can be simplified, the harvesting labor intensity is lightened, and the harvesting efficiency is greatly improved.

Description

A kind of push-and-pull cutting type asparagus collector

Technical field

The present invention provides a kind of push-and-pull cutting type asparagus collector, belongs to the agricultural field of mechanical technique of gathering.

Background technology

Asparagus has another name called asparagus; Contain physiological activators such as abundant vitamin, mineral element and asparagus polysaccharide, asparagus flavones, asparagus saponin(e; Have cancer-resisting, enhances human body immunoregulation capability, transfer blood fat, the anti-ageing function of waiting for a long time; Be one of the world's ten big famous dishes, enjoy the good reputation of " kings of vegetables " in the international market.China's planting asparagus area just reached 120,000 hm in 2008 ², having formed a huge industry, Shandong, Hebei, Shanxi Province etc. are decided to be the pillar industry of earning foreign exchange with the asparagus industry especially.Only in Cao County, Shandong, the planting asparagus area just reaches 1.2 ten thousand hm ², 200,000,000 dollars of year foreign exchange earnings.

Asparagus was earthed up in preceding 1～2 week of gathering, and the drying that requires to earth up is loosened, ventilated good but can not have sunlight to penetrate, in order to avoid asparagus becomes green.When gathering, before the sun came out, the peasant held asparagus knife; See when the asparagus root that bassets is arranged, dial some soil with left hand, see the head of asparagus root after; Dial some soil again,, then the asparagus knife in the right hand is pricked in the past towards the direction at asparagus root base portion place until the direction of growth of seeing young stem; Handle of a knife is prized to next, prized soil to asparagus root.Asparagus is generally planted and can begin to gather in back 1 year, every year twice, and each duration one wheat harvesting period, asparagus producer great amount of labor and financial resources have been wasted in this simple heavy work of gathering.

The present invention provides a kind of push-and-pull cutting type asparagus collector, and the asparagus root that this collector can be directly gathered needs proposes ground with the asparagus of cutting off then in underground cut-out, reaches the purpose that asparagus is gathered.Characteristics such as that this collector has is small and exquisite, portable, flexible operation have greatly alleviated the labour intensity that asparagus is gathered, and have improved the asparagus efficient of gathering.

Summary of the invention

The object of the invention provides a kind of push-and-pull cutting type asparagus collector.The asparagus root that this collector can be directly gathered needs proposes ground with the asparagus of cutting off then in underground cut-out, reaches the purpose that asparagus is gathered.Its technical scheme is:

Comprise handle, spring, pull bar, fixed mount, clamper, rocking bar and blade.

Described push-and-pull cutting type asparagus collector is equipped with up and down two spacers on the handle, mounting spring between two stators is used for resetting behind the blade tractive, and the lower end and the fixed mount of handle are fixed with nut.

Described push-and-pull cutting type asparagus collector, pull bar upper end arm-tie is connected with handle, arm-tie be positioned at time spacer above; Below the spring; There is certain flexibility the pull bar lower end and links to each other with rocking bar, is convenient to handle rocking bar, with traction blade with reset; There is guide rail the pull bar upper end, is convenient to moving up and down of pull bar.

Described push-and-pull cutting type asparagus collector, the fixed mount upper end links to each other with handle and fixes with nut, and the lower end links to each other with clamper with screw rod, nut and is fixing.

Described push-and-pull cutting type asparagus collector, clamper hollow, the first half is a cuboid, and Lower Half is a wedge structure, is beneficial to insertion soil to reduce resistance, and the lower end of wedge shape forms a triangular blade backplate, the protection of blade when being convenient to bury.

Described push-and-pull cutting type asparagus collector, the upper end of rocking bar is fixed on the clamper with joint pin respectively, and the inwardly flat folding in the lower end of rocking bar is beneficial to blade and fixes, and flat folding part is divided can install joint pin, is convenient to fixing and changing of blade.

Its operation principle is: when asparagus root exposes soil soon, along the direction of growth of asparagus root, hold handle and press down; Utilize the strength of fixed mount that clamper is inserted soil, make the inside of asparagus root, then with drawing pull bar on hand at the hollow clamper; Pull bar affects rocking bar, makes blade in clamper, laterally move, and cuts off asparagus root; Last handle utilizes the strength of the inner soil of clamper that asparagus root is proposed ground, can take out asparagus root.Releasing lever utilizes the strength pushing drawing rod of spring and rocking bar that blade is resetted then, carries out the operation of next round.

The present invention compared with prior art, bend over significantly when having avoided the operator to gather, straight waist repeat the action of gathering, directly native face is proposed asparagus root, simplified the asparagus root program of gathering, alleviated the labour intensity of gathering, greatly improved the efficient of gathering.
