Abstract

The utility model relates to a seeder which can dibbling irregular seeds in precision, composed of a seed taking and sowing mechanism, a driving mechanism and a travelling and supporting mechanism; the seed taking and sowing mechanism and the driving mechanism are installed on a common machine frame; the travelling and supporting mechanism are respectively installed at the front and the back ends of the machine frame. All rotating shafts of the seed taking and sowing mechanism, the driving mechanism and the travelling and supporting mechanism are mutually parallel and vertical with the longitudinal axis of the machine frame. As for the seed taking and sowing mechanism, seed taking fossae (the seed taking fossae are composed of flat seed taking foveae and vertical seed taking foveae) are equidistantly distributed along annular grooves on a seed taking and sowing roller, and sowing tongues are prearranged at the bottom parts of the annular grooves. The driving mechanism is composed of a chainwheel, a chain and a rotating shaft; the chainwheel, the chain and the rotating shaft are driven by a hand crank. The travelling and supporting mechanism is composed of a fossa pressing roller and back wheels; fossa pressing salient heads of the fossa pressing roller are conical.

Description

Smart amount seed dibbler

The utility model belongs to agricultural machinery, is a kind of sower of energy precision point sowing irregularity seed, is particularly useful for the program request ginseng seeds.

China's cultivation genseng always adopts artificial some broadcast mode, and efficiency is low, wastes seed again, and everyone per hour can only program request 5m ², usually incur loss through delay the best sowing time.The applicant in January 10 nineteen ninety-five application name to be called " seed dibbler " patent No. be 95200064.4 utility model patent, as shown in Figure 3, it gets kind of roller inner chamber the push rod (33) that is the radiation distribution, push rod is connected with little pin (35), also have cam (34) and spring (36), construct very complicatedly, make and to take a lot of work, to take material, also usually break down in the use.

The purpose of this utility model is on the basis of former patent 95200064.4, at former patent weak point, provide a kind of energy equidistant, smart amount is sowed at level land or slope with the seed points of irregularity, and can guarantee the essence amount seed dibbler of emergence rate, its simple structure, labor and material saving, easy break-down not in the use.

The purpose of this utility model realizes with following proposal, and smart amount seed dibbler is by kind of the sowing mechanism of getting that is installed on same central rack, and driving mechanism and the walking and the supporting device that are installed on the frame front and back end respectively constitute; Whole turning cylinders of the above 3 mechanism are parallel to each other and all the longitudinal axis with frame is vertical; It gets kind of sowing mechanism is to equidistantly distribute kind of the nest of getting of getting kind of a nest (15) and the upright concentric hollow cylindrical structure of getting kind of a nest (16) formation by flat along cannelure (27) getting kind sowing roller (12), the sowing tongue (18) that is preset in cannelure (27) bottom is arranged, its driving mechanism is sprocket wheel and the chain that drives with hand crank (3), to drive each turning cylinder, its walking and supporting device are nest-pressuring roller (25) and trailing wheel (13), and the nest-pressuring raised head of nest-pressuring roller (22) is conical.

Advantage of the present utility model is: compared with prior art, can reach to get at every turn and plant one, because when getting kind flat nest flat advance a seed, upright nest has just advanced not go seed under flat nest, enter a seed if upright nest is standing, and flat nest enters kind of the period of the day from 11 p.m. to 1 a.m again will be planted the roller removing clearly, so upright nest also can only be got a kind, so just can be as accurate as and only broadcast a seed at every turn, except that program request ginseng kind, but seeds such as program request corn, soybean, Chinese sorghum still.

Description of drawings:

Accompanying drawing 1 is a cross-sectional view of the present utility model;

Accompanying drawing 2 is the axial part sectioned view of Fig. 1;

Accompanying drawing 3 is the organigram of No. 95200064.4 patents of correlation technique the applicant approved;

1-2 illustrates in detail to the utility model below in conjunction with accompanying drawing: also be that embodiment of the present utility model is shown in Fig. 1-2.

A, get kind of a sowing mechanism, it is axial along it to get kind of sowing roller (12), on the cylinder curved surface, be distributed with several cannelure (27), equidistantly distributed along cannelure (27) and to have got kind of a nest (15.16), get kind of nest by flat kind of a nest (15) and upright kind of a nest (16) formation of getting of getting, both are concentric hollow cylindrical structure, and sowing tongue (18) is fixed on frame (11) bottom, and its front end injects the bottom of cannelure (27).

B, driving mechanism adopts the sprocket wheel chain drive, by the hand crank (3) that sets on driving shaft (26), chain (4), be loaded on the nest-pressuring roller sprocket wheel (24) on the pcketing roll shaft (23), set in getting kind getting kind of sowing roller chain (17) and setting clear kind of roller chain (32) on clear kind of roll shaft (31) and driving chain (6) (5) and (2) constitute by manpower rocking-turn hand crank (3) and pass through driving chain (6) and (5) respectively on the sowing roll shaft (19), drive nest-pressuring roller (25) and the clear roller (8) of planting, drive indirectly by nest-pressuring roller sprocket wheel (24) and driving chain (2) in addition and get kind of a sowing roller (12).

C, walking and supporting device are the trailing wheel (13) that is loaded on the nest-pressuring roller (25) of frame (11) front end and is loaded on frame (11) rear end, and there is number row conical nest-pressuring raised head (22) on the surface of nest-pressuring roller (25) along its circumference and axial distribution.

In the middle of the use, when getting kind a sowing roller (12) rotation, get kind of nest (15 facing to the sub-box of top seed storage tank (10), 16), flat or standing and enter a seed, exceed the unnecessary seed of getting kind of nest and planted the roller removing clearly, get back in the seed storage tank, get kind of a nest (15 and enter, 16) seed rotates with roller, is taken out of seed storage tank (10), protects kind of a cover (20) and enter, protect kind of cover (20) and seed dropping hole (30) is being arranged perpendicular to the place, ground, rack-mounted sowing tongue, front end put in the cannelure (27), fetch seed when getting kind of a sowing roller (12), get kind of a nest and forward when below to, shoveled out in the hole nest of broadcasting the nest-pressuring roller extrusion by sowing tongue (18), finish the task of sowing, because of getting kind of nest (15,16) can only get a seed, measure the purpose of planting so can reach essence, per hour can sow 800m ²-1500m ², be artificial program request 160-300 doubly, except that the program request ginseng seeds, get kind of a nest size as change, but also seeds such as program request corn, soybean, Chinese sorghum.

Be with rubber ring (7) in the clear roller periphery of planting, together rotate with clear kind of roller, its peripheral tangential motion direction is opposite with the contiguous direction of motion of getting kind of roller, and the nationality friction is removed unnecessary seed.Kind of a storage tank (10) end opening with get kind the parallel two slat gum ropes (29) that are equipped with of sowing roll axis, its friction of nationality is set upright seed and it is correctly fallen into get in kind of the nest (15,16).
