Abstract

The utility model discloses a yam harvester, which comprises a stand, a suspension arm, a ditching knife chain and a vibrating soil loosening and fruit lifting device, wherein the stand is connected with a motor vehicle through the suspension arm and is provided with a transfer case; the transfer case is connected with the motor vehicle through a universal transmission shaft; an output end of the transfer case is connected with a driving wheel and the vibrating soil loosening and fruit lifting device respectively; and the driving wheel is connected with a ground wheel through the ditching knife chain. By using the yam harvester of the structure, longer yams can be prevented from being broken during yam harvesting by farmers, and the working efficiency of the farmers is increased.

Description

Chinese yam harvester

Technical field

The utility model relates to farm machinery, especially relates to a kind of Chinese yam harvester.

Background technology

Chinese yam has long plantation historical in China, and when the results Chinese yam, need the soil around the Chinese yam be dug and open, otherwise, very easily longer Chinese yam is fractureed.Owing to when Chinese yam is gathered in the crops, all will turn over the plane soil more deeply, labour intensity is bigger, and existing reaping machine is prone to Chinese yam is fractureed when Chinese yam is gathered in the crops owing to the structure setting is unreasonable, influences Chinese yam output, reduces peasant's operating efficiency simultaneously.

The utility model content

The purpose of the utility model provides a kind of Chinese yam harvester, can make the peasant when the results Chinese yam, avoid improving peasant's operating efficiency with fractureing than the Chang Mount medicine.

For realizing above-mentioned purpose; The utility model provides a kind of Chinese yam harvester, comprises frame, suspension arm, ditching knife chain and the vibration fruit device that loosens the soil liter, and said frame links to each other with motor vehicle through said suspension arm; Said frame is provided with transfer case; Said transfer case links to each other with motor vehicle through universal drive shaft, and the output of said transfer case is connected with driving wheel and the said vibration liter fruit device that loosens the soil respectively, and said driving wheel passes through the ditching knife chain and links to each other with land wheel.

Preferably, said transfer case links to each other through eccentric wheel and the said vibration fruit device that loosens the soil liter.

Preferably, be provided with the adjusting upper connecting rod between said suspension arm and said frame.

Preferably, be provided with earth separation plate above the said ditching knife chain.

Preferably, be provided with tensioning cutter chain frame above the said ditching knife chain.

Preferably, the said vibration fruit device that loosens the soil liter comprises connecting rod, perching knife and liter fruit tailgate.

Therefore, the utility model adopts the Chinese yam harvester of said structure, can make the peasant when the results Chinese yam, avoid improving peasant's operating efficiency with fractureing than the Chang Mount medicine.

Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.

Description of drawings

Fig. 1 is the structural representation of the utility model Chinese yam harvester embodiment;

Fig. 2 be among the utility model Chinese yam harvester embodiment land wheel the protecting cover structural representation.

Embodiment

Fig. 1 is the structural representation of the utility model Chinese yam harvester embodiment; As shown in Figure 1; Comprise frame 1, suspension arm 2, ditching knife chain 3 and the vibration fruit device 4 that loosens the soil liter, frame 1 links to each other with motor vehicle through suspension arm 2, through suspension arm 2 linking together present embodiment and motor vehicle; Motor vehicle is generally farm tractor described in the present embodiment, when Chinese yam is received as the power input device of present embodiment.Frame 1 is provided with transfer case 5; Transfer case 5 links to each other with motor vehicle through universal drive shaft 6; The output of transfer case 5 is connected with driving wheel 7 and the vibration liter fruit device 4 that loosens the soil respectively, and driving wheel 7 and vibration liter fruit device 4 iterative motion under the effect of motor vehicle that loosens the soil is accomplished the course of work of present embodiment.Transfer case 5 links to each other through eccentric wheel 9 and the vibration fruit device 4 that loosens the soil liter, and the vibration liter fruit device 4 that loosens the soil comprises connecting rod 41, perching knife 42 and rises really tailgate 43.Driving wheel 7 links to each other with land wheel 8 through ditching knife chain 3, and ditching knife chain 3 tops are provided with earth separation plate 31, is used for both sides soil separately being convenient to ditching knife chain 3 iterative motions.

1 of suspension arm 2 and frame are provided with regulates upper connecting rod 10, regulates upper connecting rod 10 through adjustment, regulates and vibrates liter terrain clearance of fruit device 4 of loosening the soil, and is convenient to present embodiment work.

Said ditching knife chain top is provided with tensioning cutter chain frame, is used for adjusting the length degree of tightness of ditching knife chain, is convenient to the working depth of user according to the Chinese yam demand adjustment present embodiment of different cultivars, makes things convenient for the user to use.

Come present embodiment is further explained through the course of work of present embodiment below.

With present embodiment with after motor vehicle is connected; Motor vehicle becomes the power input source of present embodiment, and motor vehicle flows to driving wheel 7 and the vibration liter fruit device 4 that loosens the soil through universal drive shaft 6 and transfer case 5 with power, drives driving wheel 7 and vibration liter fruit device 4 iterative motions that loosen the soil; Driving wheel 7 links to each other with land wheel 8 through ditching knife chain 3; Drive land wheel 8 and travel forward together,, thereby accomplish the operation of loosening the soil because ditching knife chain 3 is provided with cutter tooth 32.Transfer case 5 links to each other through eccentric wheel 9 and the vibration fruit device 4 that loosens the soil liter; Eccentric wheel 9 can be shape fluctuated and back and forth rotate under dynamic action, because eccentric wheel 9 links to each other through connecting rod 41 and the vibration liter fruit device 4 that loosens the soil, therefore also drive vibration and loosen the soil liter really that a device 4 is rising in the process of advancing and the decline mode is moved; Thereby Chinese yam is held out ground under liter drive of fruit tailgate 43; Perching knife 42 plays the effect of loosening the soil in advancing, thereby avoids improving peasant's operating efficiency with fractureing than the Chang Mount medicine.

In addition, land wheel 8 adopts labyrinth type grave mound structure in the present embodiment, and Fig. 2 is the protecting cover structural representation of land wheel 8 in the present embodiment, and it is nested against one another that preceding protecting cover and back protecting cover are several fonts, avoids soil to get into land wheel 8 inside, influences land wheel 8 operate as normal.

What should explain at last is: above embodiment only in order to the explanation the utility model technical scheme but not limit it; Although the utility model has been carried out detailed explanation with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical scheme of the utility model, also can not make amended technical scheme break away from the spirit and the scope of the utility model technical scheme and these are revised or be equal to replacement.
