Description

Taro harvester

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to taro harvester.

Background

Taro is an important vegetable and food crop, has high nutritive and medicinal value, and is widely planted in southern areas. The tubers of the taros are main edible parts, and because the tubers of the taros are buried in soil, the soil around the taros is excavated by a traditional harvesting means by manually using a hoe, and finally, the tubers of the taros are lifted up completely, so that the taros are harvested. However, with the progress of agricultural modernization, the planting amount of the taros is gradually enlarged, the efficiency of the manual harvesting method cannot keep up with the increase of the planting amount, the labor cost is higher and higher, and the research and the application of the harvesting machine are very important in order to solve the problem of low-efficiency taro harvesting condition.

Taro plantation generally has a plurality of side by side ridges, and every ridge is neatly and evenly planted a row of taros, and there is a way on the ridge edge for people or agricultural machine's walking wheel to walk. Therefore, mechanized taro harvesting is possible.

The prior art of the existing taro harvester is inquired:

1. a multifunctional taro harvester; application No.: CN 201810579503.7; the applicant: university of Hainan; and (3) abstract:

the invention relates to a multifunctional taro harvester which comprises an excavating system, a conveying system, a traveling system, a soil separating system and a grading collecting system, wherein the excavating system comprises a dozer blade and a rotary table; the conveying system comprises a dozer blade and a conveying screen; the advancing system comprises a traction rod, a rotary table, an advancing wheel and a rack; the soil separation system comprises a conveying sieve and a grading harvesting box; the grading and collecting system comprises a motor, a transmission gear, a connecting rod, a grading harvesting box and a screening rod. The taro harvester is a harvesting machine integrating harvesting and grading screening, a dozer blade penetrates into the ground surface to harvest taros through the traction work of a tractor, a conveying sieve conveys the taros to a grading harvesting box, the soil is shaken off by the periodic swing of the grading harvesting box, and taros with different volumes can be collected in a grading manner. The taro harvester is simple in structure and convenient to operate, realizes the integration of taro harvesting and grading, can improve the taro collecting level, and drives the development of the taro industry.

However, the existing taro harvester has the defects of inconvenient running in a taro plantation, not compact mechanism, inconvenient steering and the like.

Disclosure of Invention

The utility model provides a can dig out taro tuber harvester fast, completely, the technical scheme of the utility model is realized like this:

a kind of taro harvesting machine, the share is fixedly mounted on the foremost end of the plow stock, the chain conveyer belt is mounted on plow stock and connected with share, the belt pulley fixedly mounted on harvesting machine drives the chain conveyer belt through the drive mechanism; a skid is arranged below the plow frame, and a traction frame is arranged above the front of the plow frame. The front of the traction frame is connected with a tractor and other traction machines, the harvester is pulled to move forward to plough the field, the ploughshare goes deep into the ground surface to turn up the taros planted on the surface layer of the field ridge, the turned-up taros enter the chain conveyor belt from the ploughshare to roll and move to the tail of the harvester, the connecting rod and the taros are scraped while the chain conveyor belt rolls, soil on the surface of the taros is cleaned, and the soil is screened off from the chain conveyor belt and returns to the field; finally, taros fall on the field ridges neatly from the tail of the harvester, and workers only need to pick up the taros subsequently. A skid below the plough frame contacts with soil and slides to support the harvester; the skid walks on the inter-ridge path beside the ridge.

The plough share is wedge-shaped and is provided with a plurality of vertical waist holes; the wedge-shaped tip of the ploughshare is inserted into soil, and the vertical waist hole can remove a part of soil on the surface of the taro and fall back to the field from the waist hole.

Baffles are arranged on two sides of the chain conveying belt; the baffle limits the taro in the middle of the chain conveyer belt, and the taro is prevented from dropping from two sides of the chain conveyer belt.

The transmission mechanism comprises a shaft, a driving wheel, a driven wheel and a chain; the belt pulley passes through the belt and links to each other with the traction machinery's in the place ahead belt pulley, and traction machinery's internal-combustion engine provides belt pulley rotation drive power, and belt pulley drive axle rotates, and the axle drives the action wheel and rotates, and the action wheel passes through the belt and drives from the driving wheel rotation, and it is coaxial with the driving gear of chain conveyor from the driving wheel, and then drives the chain conveyor and rotate.

The tail end of the plow stock is obliquely and downwards provided with a soil sieving grid, and the soil sieving grid is connected with the discharge end of the chain conveyor belt; soil screening grid will follow the taro of chain conveyer belt unloading and roll down to ridge ground through the slope, prevent taro surface damage, also further clear away taro surface earth.

The chain conveyer belt comprises two groups of driving gears, driven gears and chains which are parallel, and connecting rods are fixed between corresponding sections of the two groups of chains; and then constitute and use the transmission band on connecting rod as the surface, taro surface soil slick can drop to ridge ground fast.

The utility model has the advantages that:

1. the utility model is a taro harvester which collects harvesting and sifts mud, and can complete the automatic harvesting operation of taro planted on the shallow layer of the earth surface; the device has the characteristics of simple and compact structure and convenience in maintenance.

2. The ploughshare can dig tuber crops deep into the earth surface, the taros can shake off most of soil through the chain conveyer belt and the soil sieving grid plate to ensure that the dug tuber crops directly fall on the earth surface of the ridge field for subsequent harvesting, and the shortcoming that the travelling wheels of the traditional harvesting machine are easy to sink into the earth can be overcome.
