Description

Potato planter

The utility model relates to agricultural machinery technological field, is specifically related to a kind of potato planter.

Domestic existing potato planter, particularly middle-size and small-size planting machine are generally taked single ridge list group spoon chain feed mechanism, the kind spoon shape on big pit, flat narrow limit, and kettleholder weak point, spoon and chain are nearer, have the problem of sowing hole rate height, replay rate height and seeding quality difference.

1, because the seeding of single group spoon chain, spoon chain movement linear velocity height is planted spoon and is filled kind badly, and it is more to produce empty spoon broadcast leakage phenomenon.

2, kettleholder is short, and spoon and chain distance are near, and holder is planted between the spoon chain, and it is more to produce resowing phenomenon.

3, pit is big and dark, the kind spoon shape that the edge is flat and narrow, and one spoonful of multiple phenomenon is more.

The purpose of this utility model is to provide a kind of potato planter, and it is good to have a seeding quality, hole rate, the characteristics that the replay rate is low.

The utility model is described in further detail at first to draw accompanying drawing below;

Fig. 1 is the front view of the utility model potato planter;

Fig. 2 is that the A of the utility model Fig. 1 is to view;

Fig. 3 is that the B of the utility model Fig. 1 is to view;

Fig. 4 is the front view of the utility model spoon chain;

Fig. 5 is that the A-A of the utility model Fig. 4 is to view.

As shown in the figure, the utility model is by mainframe 2, front beam 35, kind case 1, feed mechanism, row The compositions such as fertile mechanism, transmission mechanism, plough 25, land presser 5, coverer 6, mainframe 2 is installed On front beam 35, feed mechanism is installed at the middle part of mainframe, feed mechanism by upper and lower feed shaft 23, 28, upper and lower seeding sprocket wheel 21,8 and two groups of spoon chains form, upper feed shaft 23 two ends are by bearing block 33 Support, the middle part is connected with lower seeding sprocket wheel 8 pattern chains, and upper seeding sprocket wheel 21 trackslips at upper feed shaft 23, Upper feed shaft two ends are supported by upper spring seat 20, spring 42 and lower spring cup 41, and the spoon chain is by up and down seeding Axle and upper lower sprocket support, and the spoon of descending spoon chain is in grain conductor; Transmission mechanism is by land wheel 9, land wheel Axle 13, door shape ground wheeling rack 10 and land axle prop up handle 37 and form, the left and right sides circular beam of door shape ground wheeling rack 10 Be connected by the beam of U-shaped clamp 40 with mainframe 2, portal trestle bottom and land axle prop up handle by adjustment Bolt 38 connects, and portal trestle top is connected with adjusting screw 18, and seeding is installed initiatively in the land axle two ends Sprocket wheel 12 is articulated by movable sprocket 27 by seeding driving-chain 30 and seeding, and the land axle left side is the row of being equipped with also Fertile drive sprocket 11 is articulated by movable sprocket 14 by the fertilizer on fertilizer driving-chain 29 and the fertilizer expelling shaft 39, Kind of case 1, fertilizer mechanism, plough 25, land presser 5 and coverer 6 are set respectively on the mainframe.

Described spoon chain is by kettleholder 32, seeding spoon 3, plant pulling needle 22 clearly and seeding chain 7 forms, kettleholder 32 One end equidistantly is welded on the seeding chain 7, on the kettleholder other end welding seeding spoon 3, plants clearly pulling needle 22 and is welded in The back of kettleholder is also vertical with kettleholder, equidistantly stagger between the adjacent spoon on two groups of spoon chains, spoon and chain it Between separated by right baffle-plate 15, right baffle plate 16 and middle baffle plate 17. Also be provided with feed mechanism on the mainframe Lead kind of bend pipe 34, lead kind of straight tube 24, seed guiding groove 36, fill kind of pipe 4 and gear kind of a groove 26.

Fertilizer mechanism is made up of fertile case 19, fertile box bracket 31, fertilizer expelling shaft 39, fertilizer follower 14, fertilizer driving-chain 29 and fertilizer drive sprocket 11.

The course of work of the present utility model be by transmission mechanism power is passed to simultaneously about two spoon sprocket wheels at two following feed shafts and this feed shaft middle part, two spoon chains of following spoon chain wheel drive, the spoon chain is around feed shaft and spoon chain crop rotation circulatory motion up and down up and down, and then two groups of kind spoons are realized continuously evenly seeding operation along with the spoon chain is made well-regulated shuttling movement.

The utility model list ridge two spoon chain, two groups of kind spoons alternately fill kind of a seeding, do not disturb mutually, can be designed to three on single ridge or many seeds-sowing spoon chains on this architecture basics.

The ground wheeling rack of the utility model transmission system and ground wheel assembly design are unique, compact conformation, and the portal trestle dependable performance is convenient to adjust.

Two ridges of this machine one-stop operation, it is supporting to can be single ridge and animal power on this basis, also can many ridges and large and middle tractor supporting, power source can be exported by land wheel, also can be exported by tractor driving wheel.

The utility model compared with prior art, the one, be the two spoon chain seedings of single ridge by the single spoonful of chain seeding in single ridge, under certain condition, can reduce gearratio in the cave, can reduce a spoon chain linear velocity, solution is filled and is planted and seeding quality difference problem; The 2nd, kind of spoon shape is improved to the big edge of small rut by the little edge of big pit, and the edge angle of declination changes from small to big, and little kind of the spoon that can solve of pit is once got kind of the many and high problem of replay rate; The 3rd, kettleholder is long by weak point, adds the distance of strockle and chain, can solve holder kind of problem between spoon and the chain; The 4th, to set up on the kettleholder to plant clearly and dial pin, the kind piece that kettleholder can be entrusted pulls out; The 5th, the combination that a shape ground wheeling rack, land axle prop up handle and land axle has realized the land wheel adjustable height, row spacing is adjustable; Portal trestle to front hook or backward corner adjust the driving chain rate of tension simultaneously, deducted seeding chain regulating wheel, simplified structure, can solve the chain drive reliability.
