Abstract

The utility model relates to a yam harvester, which is composed of a cutting band saw, a scarification plate and a scroll elevator. The band saw at the front cuts around a yam ditch, the upper part of the band saw is connected with a rotating wheel, the middle part of the band saw passes through a slender opening, the lower part of the band saw is sleeved on a bearing, the scarification plate at the middle looses soil following the band saw, the scarification plate is fixed on a telescopic link in a sleeve, an oil pressure pump provides power, the scroll elevator at the rear part rotates upwards at the lower part of cut soil, so yam can be pushed out upwards. Because of adopting a tractor as power, the cut soil is larger than the yam ditch, the yam harvester arches upwards from the bottom of the yam, the integrality of the yam is not only ensured, the yam is not broken, but also the original form of the yam ditch is kept, the working efficiency is greatly improved, and three to five mu of yams can be dug everyday.

Description

Chinese yam harvester

Technical field

The utility model belongs to the harvest machinery of crops harvesting equipment, particularly a kind of Chinese yam.

Background technology

At present, people during Chinese yam, mostly are to adopt manual type in results, promptly excavate with spade, like this results both took a lot of work, time-consuming, can only dig about 30 meters for each person every day, but also easily Chinese yam be fractureed.Now, the telescopic excavation of employing is arranged also, exactly a sleeve is entangled Chinese yam, firmly press down and Chinese yam is taken out, but, Chinese yam is fractureed, and can only dig for each person every day about half mu, inefficiency because growing way of Chinese yam and length are difficult for grasping by machinery.

Summary of the invention

The purpose of this utility model will provide a kind of Chinese yam harvester that adopts machinery to excavate, do not damage Chinese yam, high efficiency exactly.Basic structure of the present utility model is: frame is divided into outer frame and interior framework, outer frame is a rectangle, on wheel is housed, interior framework is positioned at the centre of outer frame, its height can be in the outer frame adjusted, also the degree of depth of just correspondingly having regulated cutting and having promoted is generally regulated between 100 to 150 centimetres.On interior framework, be fixed with three parts: the one, cutting part, it adopts the band saw form, in the band saw ring, one rotating shaft that is fixed on the outer frame is arranged at top, and the one end is provided with runner and band saw fixes, the other end has a belt pulley, link to each other with diesel engine by belt, the bottom is enclosed within on the flute profile baffle plate fixing on the interior framework, is fixed with three to six bearings on the flute profile baffle plate, band saw is formed a band saw ring just by the bearings of the runner on top and bottom.The 2nd, the part of loosening the soil, it is made up of two L-shaped steel plates, top links to each other with expansion link, the bottom is limited in the inboard movable of flute profile baffle plate, and sleeve pipe is fixed on the interior framework, and it is a hermetically-sealed construction, one end is connected to oil pressure air pump on the diesel engine by a pneumatic tube, expansion link in the other end can stretch therein, and the plate front and back of loosening the soil that drive is fixed in the above are scooped up moving, with cubic metre of earth further the becoming flexible of front band saw cutting.The 3rd, the spiral lift portion, it is aliform in the shape of a spiral, rotating shaft is fixed on the support in the middle of it, there is a rotating shaft on the support side, be fixed on the interior framework with an axle sleeve in the middle of the rotating shaft, there is a runner upper end, links to each other with diesel engine by belt, also there is a runner lower end, links to each other with runner in the screw elevator rotating shaft by belt.Whole interior framework can be on outer frame be adjusted height up and down, use when adapting to the Chinese yam of excavating different depth and carrying.During use, dig a hole in the termination of plantation Chinese yam ditch in advance, the width and the degree of depth of being a bit larger tham the Chinese yam ditch lie in outrigger on the groove face of Chinese yam ditch, and tractor is preceding starting, top diesel engine provides power to reaping machine, the band saw of front is around Chinese yam ditch cutting, middle loosen the soil plate along with after soil is further loosening, last screw elevator upwards rotates in the earthwork bottom of cutting, can upwards eject 20 to 40 centimetres to Chinese yam, get final product by manually extracting.Owing to adopt tractor as power, the earthwork of cutting is greater than the Chinese yam ditch, from the bottom of Chinese yam to arch, not only guaranteed the integrality of Chinese yam, the Chinese yam that do not fracture, and kept the original appearance of Chinese yam ditch, operating efficiency greatly improves, and can excavate three to five mu of Chinese yams every day.

Embodiment

As shown in Figure 1,

Interior framework 1 is mainly two cross bars, long 30 centimetres, there is sleeve pipe the termination, be enclosed within the carrying on the ear shape framework montant of outer frame 16 two ends, and can move up and down, make its location with pin along its montant, the degree of depth that can regulate cutting and promote, outer frame is wide to be 60 centimetres, the Chinese yam ditch can be covered, and the Chinese yam ditch generally is 50 centimetres wide.Rotating shaft 3 is fixed on the outer frame by axle sleeve, and the one end is fixed with runner 2, and the other end also is provided with runner, links to each other with diesel engine on the tractor by belt.On interior framework, be fixed with three parts: first is a cutting part, front end at interior framework 1, be fixed with a flute profile baffle plate 6 that connects, flute profile baffle plate 6 is a steel plate material, and its bottom port place is fixed with five bearings 5, the outer shroud of bearing protrudes from the outer surface of flute profile baffle plate, between two cross bars of flute profile baffle plate and interior framework, have a thin-and-long opening, band saw 4 tops connect runner 2, the thin-and-long opening is passed in the centre, make band saw not produce displacement, be limited in the thin-and-long opening, bearing is entangled in the bottom, band saw 4 is just by the bearings of the runner on top and bottom, form a band saw ring, band saw is the steel alloy material, and its width is 15 centimetres, cutting width is 50 centimetres, can be with the bottom and the both sides cutting of whole Chinese yam ditch.Second portion is the part of loosening the soil, in the middle of two cross bars of interior framework 1, be respectively arranged with a fixed frame 7, fixed frame 7 is a long frame shape shape, and center fixed has a sleeve pipe 8, and sleeve pipe 8 is a hermetically-sealed construction, one end has a joint 9, lead to the oil pressure air pump of tractor with a soft rubber tube, the other end has an expansion link 10, on the expansion link 10, be fixed with the plate 11 that loosens the soil, it is L shaped shape, and length is greater than 150 centimetres, and width is 20 centimetres, the lower end horizontal spacing of two plates that loosen the soil is greater than 10 centimetres, the stretching motion of expansion link 10 in sleeve pipe 8 drives the plate 11 that loosens the soil and also does corresponding activity, further makes the soil after the cutting loosening.Third part is the spiral lift portion, screw elevator 12 is conical, 30 centimetres of last diameters, 80 centimetres of following diameters, high 50 centimetres, be wound with helical form fin 13 around the outside, its rotating shaft 19 is fixed on two horizontal stands 14, and horizontal stand is connected to a fixed with two perpendicular supports 15 that are fixed on two cross bars of interior framework again.Be fixed on rotating shaft 17 on the interior framework cross bar by axle sleeve, its upper end is provided with a runner 18, links to each other with diesel engine on the tractor with belt, and the runner of its lower end passes through belt, links to each other with the runner of rotating shaft 19 lower ends in the elevator 12.(dotted portion illustrates in Fig. 3).
