Description

A kind of crawler belt is from walking dry type water chestnut harvester

Technical field

The utility model relates to crop harvesting technical fields, walk dry type water chestnut harvester certainly more particularly to a kind of crawler belt.

Background technique

Horseshoe is a kind of crop being planted in shallow-layer slowly drained soil, and the stolon apex for being grown on underground expands for ball Stem, this bulb are widely used as fruit or vegetables because of nutritional ingredient with higher with edible；China produces horseshoe per year about Ten thousand tons of 60-80, horseshoe is exported to the states such as South Korea, Japan, the U.S., Canada, Hong Kong and Association of South-east Asian Nations as important export-oriented commodity Family and area.The bulb of horseshoe is grown on 20~25cm of earth's surface or less more, and the harvesting approach of horseshoe plantation at present is still very backward, Manual work mode is mainly used, low efficiency, time-consuming, at high cost.Light is harvest link, average to need 20-30 people per acre Work harvesting.Light harvests about 2000 yuan/mu of cost, accounts for 1/5 or so of horseshoe income.Backward production method seriously constrains horseshoe The large-scale development of industry, and be also easy to cause the damage of water chestnut using hand digging, therefore, people's utility model horseshoe Cropper greatly improves the efficiency of crop to horseshoe in muddy ground, meets the needs of actual cut.

Chinese patent: a kind of water chestnut harvester, application number 201620638124.7, applying date 2016.06.18, authorization are public Announcement CN 205681862 U, authorized announcement date 2016.11.16, disclose a kind of water chestnut harvester, including crawler belt fuselage (1), Weeding mechanism (2), collecting mechanism (3) and sorting mechanism (4)；The crawler belt fuselage (1) is equipped with rack (11), rack (11) bottom is equipped with Athey wheel (111)；Weeding mechanism (2) and collecting mechanism (3) are movably arranged on rack (11) front end, screen Mechanism (4) is mounted in the middle part of rack (11)；Rinse bath (6) are equipped between collecting mechanism (3) and sorting mechanism (4), rinse bath 6 Discharge port (61) are equipped with by the side of sorting mechanism (4)；Engine (12) controls transmission device (14) work, transmission device (14) weeding mechanism (2), collecting mechanism (3) and sorting mechanism (4) is driven to work respectively.The utility model acquires out Horseshoe removes the process that the later period cleans again from by rinsing well twice, and in collection process by giant to soil It is separated, to guarantee the integrality of horseshoe, remarkable in economical benefits.But the technology has the disadvantage that (1) giant rushes Horseshoe caused by brush separation soil damages, and still receives the harvests of a small amount of fresh food horseshoes, but to need to carry out secondary operation such as tank Batch harvest this drawback of demand of first-born production is then fatal damage；(2) horseshoe is perishable after damaging, being soaked, not shelf-stable.

Chinese patent: a kind of water chestnut harvester, application number 201520471332.8 (10), applying date 2015.07.03 are awarded 204762132 U of notification number CN is weighed, authorized announcement date 2015.11.18 discloses a kind of water chestnut harvester comprising tracked machine Body, earth scraper structure, rotary blade and screen frame, crawler belt right side of machine body front connect earth scraper structure by support linking arm, and shovel is native Mechanism front upper is provided with rotary blade, and earth scraper structure is provided with water conservancy diversion roller, and water conservancy diversion roller rear lower is provided with screen frame, Screen frame top is connected with sieve by sieve rocker arm, and screen frame is connected with eccentric wheel, the eccentric wheel by rocker arm Pass through pulley drive.The water chestnut harvester power of the utility model is sufficient, cross-country ability is good, smooth ride and failure rate are low, pole Big improves horseshoe efficiency of crop, reduces cost of labor.But the technology has the disadvantage that the rotary tillage of (1) front fuselage Cutter tool in harvest easily causes to damage to horseshoe fruit.It (2) cannot be smoothly defeated after earth scraper structure scoops up soil and horseshoe It is sent to sieve.(3) due to harvest many horseshoes are still mixed in blocking soil when, are difficult to realize horseshoe from mud only with sieve It is separated in soil.

Chinese patent (utility model): a kind of double-deck shovel two-stage screening type water chestnut harvester, application number (patent No.): 204929634 U of 201520471519.8, Authorization Notice No. CN, authorized announcement date: 2016.01.06 discloses a kind of bilayer Shovel two-stage screening type water chestnut harvester, including crawler belt body, screening mechanism, conveying mechanism, rack and earth scraper structure, crawler belt body The rack promoted by hydraulic cylinder is installed, frame front is fixed with earth scraper structure, and earth scraper structure rear portion is equipped in front of right side By the conveying mechanism of hydraulic motor transmission, conveying mechanism rear portion is equipped with screening mechanism.The double-deck shovel two-stage sieve of the utility model Parting water chestnut harvester power is sufficient, cross-country ability is good, smooth ride and failure rate are low, greatly improves horseshoe efficiency of crop, Reduce cost of labor.But the technology has the disadvantage that (1) upper and lower distance for shoveling native plate is unable to adjust, and may cause fruit soil Easily shovel hurts horseshoe, the efficiency that blocked up and influence is sieved below when layer is excessively thin；(2) topsoil is led by the native subsequent fixation of plate of upper shovel Slot is arranged to fixed side, cannot be commutated, and has 50% probability to be emitted on the row not harvested, hence it is evident that increase the resistance of machine, And the fixed long friction of guide groove lead is greatly, and casting not in time, is easy to happen stifled native phenomenon；(3) due to the row using fixed guide groove Earthwork formula, the speed of travel of cropper is inevitable very slow, is not so easy blocking, has seriously affected efficiency of crop；(4) after shoveling native plate under Band-like fruit soil layer is cut into sectional mud item and is conveyed by the conveyer in face, although conveying distance can be shortened, while Increase probability of the horseshoe by cut wound.

Utility model content

In view of the above shortcomings of the prior art, the purpose of this utility model is to design a kind of crawler belt from walking dry type horseshoe harvest Machine, the machine excavate harvesting approach using the double-deck shovel, the soil layer of planting area are divided into acarpous topsoil and has the fruit of fruit Soil layer, upper layer shovel first roots out the topsoil of no growth horseshoe and quick drain is to the side of machine, and lower layer's shovel is again by fruit soil Layer scoops up, and is delivered to the separating treatment that rear end carries out fruit soil；Conveying mechanism is not segmented by the soil containing fruit, is in continuous band Shape conveys separating mechanism, crushes roller group mechanism in advance by soil adjustable in pitch, with concave-convex double roller group, band-like fruit soil layer is squeezed Pressure splits into big walk；Torn again native comb teeth roller mechanism by it is broken at the beginning of big walk, tear Xie Wei little walk, finally enter roller group fine crushing into Row is fine crushing, realizes the pre-separation of fruit and soil step by step, performs adequate preparation for subsequent screening sorting, while in structure It takes measures to avoid horseshoe impaired as far as possible.Water chestnut harvester designed by the utility model, when harvesting horseshoe by adjusting fruit The thickness of the layer is required with the harvest for adapting to different cultivars horseshoe, to realize optimal harvest effect；By the conveying and Separating mechanism avoids during processing caused by horseshoe fruit to greatest extent while guaranteeing harvest quality and efficiency Damage.It does not get wet by crawler belt from the horseshoe for walking dry type water chestnut harvester harvest, shelf-stable.
