Description

A kind of root crop reaping machine

Technical field

The utility model relates to a kind of farm machinery, particularly a kind of root crop reaping machine.

Background technology

Be used to gather in the crops the reaping machine of root crops such as potato, pachyrhizus, ginger at present, it is in results during root crop, needs earlier the seedling of crop is sliced off, and is scattered on the ground after block rhizome can only being dug from the ground, also needs manually to pick up to choose block rhizome.Workload is big, and results speed is slow.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of root crop reaping machine that can remove seedling automatically and collect block rhizome is provided.

In order to solve the problems of the technologies described above, the utility model comprises frame, colter and road wheel, be fixed with native sieves and block rhizome sieves on the described frame, the soil sieves is between colter and block rhizome sieves, frame is provided with the conveying plant I that object is passed to the rear end of block rhizome sieves on the upper surface of native sieves and block rhizome sieves and from the front end of native sieves, the below of block rhizome sieves is provided with conveying plant II.

In order to make it simple in structure, described conveying plant I comprises at least two chains and a plurality of delivery board, but being enclosed within on native sieves and the block rhizome sieves of chain gyration, being fixed on the chain of a plurality of delivery boards space.

In order to realize automatic loading, described conveying plant II is for promoting conveyer, and the low side that promotes conveyer is in the below of tuberous root stem sieves, promotes the high-end of conveyer and is in outside the frame.

For the front portion that makes native sieves can filter out soil block, the rear portion can filter out little block rhizome, the block rhizome size that reaping machine is collected meets the requirements, and the sieve aperture of described native sieves front portion is less than the sieve aperture at rear portion.

In order to make simple in structure, the good filtration effect of native sieves and block rhizome sieves, described native sieves and block rhizome sieves respectively comprise the many reinforcing bars that are arranged in parallel and are fixed on the frame, the reinforcing bar of soil sieves and block rhizome sieves is vertical with delivery board, the reinforcing bar of soil sieves has two kinds of length types, length is staggered, the reinforcing bar front end alignment of native sieves.

The beneficial effects of the utility model are: use root crops such as the utility model results potato, pachyrhizus, ginger, can slice off the seedling of crop earlier, the novel elder generation of this reality with root crop from soil, dig out, after filtering soil and little block rhizome, isolating satisfactory block rhizome of size and seedling again, block rhizome is carried by conveying plant II and is collected, seedling is scattered on the ground automatically, and conveying plant II can be with promoting conveyer, the lifting conveyer can be transported to block rhizome follows in a side lorry, realizes automatic loading.

Description of drawings

Fig. 1 is the utility model structural representation; Fig. 2 is that the A of Fig. 1 is to figure;

Among the figure: 1, hitch frame, 2, colter, 3, frame, 4, chain, 5, native sieves, 6, delivery board, 7, promote conveyer, 8, rotating shaft, 9, sprocket wheel, 10, block rhizome sieves, 11, road wheel, 12, driving wheel.

Embodiment

A kind of specific embodiment as depicted in figs. 1 and 2 comprises hitch frame 1, colter 2, frame 3, native sieves 5, block rhizome sieves 10, conveying plant I, conveying plant II and road wheel 11.

Hitch frame 1, native sieves 5 and block rhizome sieves 10 all are fixed on the frame 3, and native sieves 5 is between hitch frame 1 and block rhizome sieves 10, and native sieves 5 tilts to the back upper place, and block rhizome sieves 10 is horizontally disposed with.Soil sieves 5 and block rhizome sieves 10 respectively are made up of the many reinforcing bars that are arranged in parallel, the reinforcing bar of soil sieves 5 has two kinds of length types, length is staggered, the reinforcing bar front end alignment of soil sieves 5, make the width of the width of native sieves 5 anterior sieve apertures less than the rear portion, soil block can be filtered in the front portion, and the rear portion can filter out little potato.The reinforcing bar at reinforcing bar soil sieves 5 rear portions of the block rhizome sieves 10 of reinforcement ratio of soil sieves 5 is also sparse, and block rhizome sieves 10 can leak down to meet the block rhizome of a certain size requirement and the seedling that do not leak down.Gap between the reinforcing bar of soil sieves 5 and block rhizome sieves 10 should be according to block rhizome size requirements is set.

Conveying plant I comprises three chains 4, four 8,12 sprocket wheels 9 of rotating shaft and a plurality of delivery boards 6, four rotating shafts 8 are arranged on the frame 3, intrinsic three sprocket wheels 9 in the every rotating shaft 8, three chains are enclosed within the sprocket wheel 9 of four rotating shafts 8 respectively, one of them rotating shaft 8 is provided with driving wheel 12, can move thereby drive rotating shaft 8, sprocket wheel 9 and chain 4 by driving wheel 12 input power.Delivery board 6 is made up of an angle steel and a placing of reinforcement that is fixed on the angle steel drift angle, one side of the angle steel of delivery board 6 fixes with chain 4, the another side of angle steel is perpendicular to chain 4 and reach outside the circle of chain 4, reinforcing bar extend in the circle of chain 4, soil sieves 5 and block rhizome sieves 10 are in the circle of chain 4, make chain 4 can drive delivery board 6 from the back end motion to block rhizome sieves 10 of the front end of native sieves 5.

Conveying plant II is for promoting conveyer 7, the low side of lifting conveyer 7 extend in the frame 3 and is in the below of block rhizome sieves 10, the low side that promotes conveyer 7 can be caught the potato piece that filters out from block rhizome sieves 10, promotes the high-end outside that is in frame 3 of conveyer.

Promote the drive unit that conveyer 7 comprises support, two chains, many reinforcing bars, a plurality of riser and chain drive-belt motions, support is fixed on the frame 3, but being arranged on the support of two chain gyrations, the two ends of reinforcing bar are fixed on two chains, block rhizome can not leak down in gap between reinforcing bar, every a segment distance, just have to be fixed with a riser on the reinforcing bar.

Hitch frame 1 is fixed on the front end of frame 3, and hitch frame 1 can be connected with dilatory head, and frame 3 is provided with the transmission shaft drive that connects driving wheel 12 and dilatory head.

Using method: earlier this grain header and dilatory head are connected, tractor drives this grain header and moves in the field, and driving conveying plant I and conveying plant II work, colter 2 digs out root crop earlier, block then rhizome, soil and seedling enter into the front end of native sieves 5, under the drive of chain 4 and delivery board 6, pass to block rhizome sieves 10 from native sieves 5, in the passing process, soil is missed from the front portion of native sieves 5 earlier, be that charlotte is missed from the rear portion of native sieves 5 again, size meets necessarily required block rhizome and drains to from block rhizome sieves 10 and promote on the conveyer 7 then, block rhizome is raised conveyer 7 and is transported to and follows in a side lorry, realize automatic loading, seedling falls down scattered on the ground from block rhizome sieves 10 rear ends.
