Abstract

The utility model discloses a machinery screen for harvesting potatoes, sweet potatoes and beets. Rotating shafts 3, 4 and support frames 5, 6 are respectively arranged on the front-rear parts of two frames 1, 2 of the machinery screen. More than two gears 7 are arranged on the rotating shaft 3, and the number of gears arranged on the rotating shaft 4 is one as many as the number of the gears on the rotating shaft 3. The gear 9 which the gears arranged on the rotating shaft 4 is one as many as the gears on the rotating shaft 3 is arranged at the outside of the frame 1, and the rest gears 8 are arranged on the inner sides of the frames 1, 2. A plurality of reinforcing bars 10 are transversely and evenly welded on the support frames 5, 6. A plurality of scraping plates 11 are longitudinally lapped on the reinforcing bars 10 in equidistance. A plurality of scraping teeth 12 are arranged on the scraping plates 11; the number of chains 13 which are arranged on the gears 7, 8 is the same as the number of the gears on the rotating shaft 3. The chains 13 and the scraping plates 11 are connected by chain ears 14. In addition, a ploughshare 15 and two suspension rings 16 are also arranged on the front ends of the frame 1, 2. The utility model enables soil to completely separate from the potatoes, the sweet potatoes and the beets, so the collecting net rate of crops is raised; in addition, the chains and the gears can be effectively prevented from clamping and damaging by stones and soil blocks, so the mechanical work efficiency is raised.

Description

The harvesting sieve

Affiliated technical field

The utility model relates to a kind of mechanical sieve that gathers in crops such as potato, Ipomoea batatas, beet.

Background technology

The sieve of crops such as existing harvesting potato, Ipomoea batatas, beet, be directly to set up slide bar on chain, its shortcoming is, the one, and soil, tendril are difficult for dropping to ground, on sieve with potato or Ipomoea batatas or beet etc. mix in, can not guarantee to gather in neatly potato, Ipomoea batatas, beet etc.The 2nd, stone, soil block easily block damage chain and gear, destroy machine work.

Summary of the invention

For overcoming the deficiency of existing harvesting sieve, the utility model provides a kind of and can totally gather in potato, Ipomoea batatas, beet and make stone, soil block be difficult for the harvesting sieve that card decreases chain and gear again.

Solution of the present utility model is, this harvesting sieve respectively is provided with a turning cylinder and a support in the front and rear part of two frameworks, anterior turning cylinder is provided with two to cog, many one of the number of gears that the turning cylinder of the gear ratio front portion that the turning cylinder at rear portion is provided with is provided with, wherein a Duo gear is located at the outside of framework, remaining gear is located at the inboard of two frameworks, on support, laterally be welded with some reinforcing bars equably, vertically be erected with some scraper plates on the reinforcing bar equidistantly, the interval location place of scraper plate between reinforcing bar is provided with scraping teeth, be equiped with the chain of counting similar number with anterior turning cylinder gear on the turning cylinder gear, chain is connected by the chain ear with scraper plate, in addition, the front end at framework also is provided with a ploughshare and two links.

Owing to taked technique scheme, so when the harvesting riddler did, scraper plate and scraping teeth forced soil to drop to fully on the ground of sieve bottom, have improved the net harvesting rate of crops such as potato, Ipomoea batatas, beet greatly, and have protected chain by stone, soil block card damage; The effect of gear backplate has in addition in addition also protected gear not blocked, block bad by stone, soil block effectively, has improved mechanical operating efficiency.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model stereoscopic schematic diagram;

Fig. 2 is the utility model part frame schematic diagram.

Embodiment

As depicted in figs. 1 and 2, this harvesting sieve, at two frameworks 1,2 front and rear part respectively is provided with a turning cylinder 3,4 and one support 5,6, turning cylinder 3 is provided with two to cog 7, many one of the number of gears of the gear ratio turning cylinder 3 that turning cylinder 4 is provided with, many gears 9 is located at the outside of framework 1, this gear 9 links to each other with the driving shaft of motor vehicle, remaining gear 8 is located at framework 1,2 inboard, at support 5, laterally be welded with some reinforcing bars 10 on 6 equably, vertically be erected with some scraper plates 11 on the reinforcing bar 10 equidistantly, scraper plate 11 is provided with several scraping teeth 12, gear 7, be equiped with on 8 with turning cylinder 3 on the chain 13 of number of gears similar number, chain 13 is connected by chain ear 14 with scraper plate 11; In addition, the front end at framework 1,2 also is provided with a ploughshare 15 and two links 16.

For the protection gear is also gear backplate 17 can be set on support 5,6.

When harvesting sieve width is narrower, can establish two gears 7 on the turning cylinder 3, establish three gears on the turning cylinder 4, two gears 8 in these three gears are located at the inboard of framework 1,2, and another gear 9 is located at the outside of framework 1.

When harvesting sieve wider width, can establish three gears 7 on the turning cylinder 3, establish four gears on the turning cylinder 4, three gears 8 in these four gears are located at the inboard of framework 1,2, and another gear 9 is located at the outside of framework 1.

The working method of the utility model harvesting sieve is: two links 16 hang on the motor vehicle, and gear 9 links to each other by chain with the driving shaft of motor vehicle, and the motor vehicle drive shaft turns is ordered about gear 9 and rotated, and drive 3,4 and three chains of turning cylinder 13 then and rotate; Plough by ploughshare crops such as the potato plow, Ipomoea batatas, beet are brought to the harvesting sieve along with motor vehicle moves ahead after, under the effect of the promotion of scraper plate 11 and scraping teeth 12, soil is very fast to be separated on the ground of falling the sieve bottom with potato, Ipomoea batatas, beet, what obtain is clean potato, Ipomoea batatas, beet, reaches the purpose of results.
