Description

The end, a kind of ground crop harvester

Technical field

A kind of ground of the utility model end crop harvester relates to the mechanical designing technique field, is applicable to the crops of results ground at the end, is specially adapted to gather in the crops garlic.

Background technology

The results of the end, present stage ground crop mainly are to accomplish by manual work, and efficient is low, a lot of hinder kind occur, because the harvest time of ground end crop is shorter, are the cycle that shortens results, therefore press for machinery to replace manual work, improve results efficient and gather in the crops quality.

Summary of the invention

The purpose of the utility model is to above-mentioned weak point the end, a kind of ground crop harvester to be provided, and this machine mainly improves results efficient, solves ground end crop and can not utilize the difficult problem of mechanical harvest, thereby reduce farmer's burdens.

The end, a kind of ground crop harvester takes following technical scheme to realize: the end, a kind of ground crop harvester comprises roller, cutter, colter, pull bar, pulley, transition sieve, second delivery wheel, first gear, thumb wheel, second gear, conveyer belt, the 3rd gear, first delivery wheel, the 4th gear, wheel, first connecting rod, second connecting rod, slide block, support and sieve, and pull bar links to each other with frame, at central rack roller, cutter, colter and pulley is installed successively from front to back; Transition sieve and frame link to each other with the I axle, and second gear and second delivery wheel are installed on the I axle, and first gear and thumb wheel are installed on the II axle; The rotation that is meshed with second gear of first gear; First delivery wheel and the 3rd gear are installed on the III axle, and first delivery wheel is connected through conveyer belt with second delivery wheel, and wheel and the 4th gear are installed on the IV axle; The rotation that is meshed with the 4th gear of the 3rd gear; The V axle links to each other with the IV axle, and first connecting rod is installed on the IV axle, and second connecting rod is connected with first connecting rod; Support is installed on the frame; Support and horizontal plane have a certain degree, adjustable angle, and sieve and slide block link together; Second connecting rod is connected with slide block, and slide block drives sieve and in support, moves reciprocatingly.

The frame of described frame reaping machine.

Described support is provided with one, is the framework of a rectangle.

Described tractor can adopt civilian hand tractor.

Be equipped with at the back at said sieve and gather device, thereby realize the results of crop.

The described device of gathering adopts the scalable device of gathering of grooved.

Operation principle: a kind of ground of the utility model end crop harvester is primarily aimed in the crops of interplanting.Because interplanting crops and crop (being due-in crop) close together at the bottom of the ground that will gather in the crops; Hinder simultaneously crops easily the due-in crop of results; Then use roller as protection, roller mainly relies on the wheel and the frictional force on ground to rotate to advance, push down the soil block that colter has been ploughed.Cutter and colter remain in the same perpendicular, and cutter marks vestige with ground earlier, alleviates the colter resistance, makes soil loosening.With colter due-in crop and one in soil are ploughed, pulley alleviates transition sieve and frictional ground force, the pulley close proximity to ground, and native and due-in crop is risen by the transition sieve shovel together, because the sieve bar of transition sieve has flexibility, a part of soil is realized separating with due-in crop.Because soil and due-in crop accumulate in left end in a large number, with thumb wheel due-in crop and soil are sent into conveyer belt, the power of thumb wheel is provided by first gear and second gear.Conveyer belt is sent into due-in crop in the sieve, and conveyer belt power is provided by the 3rd gear and the 4th gear.The rotation of wheel mainly is to lean on pull bar to be connected with tractor to drive whole device, rotates through the frictional force on wheel and ground.The power of sieve comes transmission by second connecting rod and slide block.The axle of the IV axle being made similar bent axle drives second connecting rod, and second connecting rod drives slide block and in support, moves reciprocatingly, because the sieve aperture of sieve is less than harvesting crops, soil spills from sieve, and crop is stayed on the sieve, can realize that then soil separates with due-in crop.Add one at the back at sieve and gather device, due-in crop relies on the inertia backward inegration of deadweight and sieve, thereby realizes the results of garlic.

A kind of ground of the utility model end crop harvester is reasonable in design, has realized separating of due-in crop and soil, has made things convenient for due-in the crop particularly cutting and the garlic airing of garlic root, improves results efficient and results quality, shortens harvest cycle.This machine is convenient to operation, has alleviated the labour.Collection problem and the underground crop that has solved separation problem, the underground crop of underground crop and soil interplanted with crops and can not be used the problem of mechanical harvest.Realized semi-automation, shortened the harvesting time, reduced farmer's burdens.
