Abstract
The utility model relates to an agricultural seeder, in particular to an automatic soil covering device used for a membrane hill-drop planter in the hill-drop planting process. The soil covering device mainly comprises a soil covering disc rack (11) and a soil covering disc (12) which are connected with a roller frame (3). The soil covering device is characterized in that the soil covering disc rack (11) is articulated with the tail part of the roller frame (3) through an articulated shaft (6); the tail end of the roller frame (3) is provided with a spring guide rod (7); the soil covering disc rack (11) is sleeved on the spring guide rod (7); and a spring (9), a gasket and a cotter pin are arranged on the spring guide rod (7). The soil covering device has the advantages that the structure is simple and practical through the reasonable structure design, the soil covering disc is organically combined with the roller frame, the penetration depth of the soil covering disc underground is adjusted through the characteristics of the spring, so that soil covering amount can be adjusted.
Description
Technical field
The utility model relates to hill-drop planter on a kind of agricultural seeding machine, particularly film, the automatic covering device that uses in the bunch planting process.
Technical background
The precise hole sowing machine of China generally includes the bunch planting cylinder that is installed on the rolling stand at present, fertile case, earthing dish or the like, bunch planting cylinder the interior or air inhaling type fine sowing device is set outward, this device is widely used in agricultural seeder, one of advantage of precise hole sowing machine is that precision drilling is carried out synchronously with kind cave earthing, but what of the adjusting earthing amount that present kind cave covering device can not be random, consequence causes kind of a cave earthing amount to have to be had less more, inhomogeneous, can have influence on the emergence rate of seed, though that the covering device that has can be regulated the effect of how many its earthing of earthing amount is bad.
The utility model content
The purpose of this utility model is that the problem that solves above-mentioned proposition provides the covering device on the hill-drop planter on a kind of spring film.
The purpose of this utility model is achieved in that
The utility model mainly comprises earthing plate rail 11 and the earthing dish 12 that connects with roller shelves 3, earthing plate rail 11 is hinged with the afterbody of roller shelves 3 by jointed shaft 6, tail end in roller shelves 3 is provided with spring guide 7, and earthing plate rail 11 is socketed on the spring guide 7, and spring guide 7 is provided with spring 9; Tail end in roller shelves 3 is provided with spring guide 7 and 3 vertical connections of roller shelves; The lower end of the spring 9 that spring guide 7 is provided with places in the centring ring 10 that earthing plate rail 11 is provided with.
The utility model has the advantages that, the utility model has the advantages that, pass through reasonable structural design, simple and practical, make earthing dish and rolling stand organically combine, and utilize the spring self characteristics to realize regulating the degree of depth that the earthing dish gos deep into ground, to realize regulating what of earthing amount.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the partial enlarged drawing at accompanying drawing 1 II place.
Embodiment
Below in conjunction with accompanying drawing the utility model feature and correlated characteristic thereof are described in further detail:
Wherein, the label among Fig. 1-2 is represented respectively: 1-frame, 2-cylinder pulling shaft, 3-roller shelves, 4-press mold wheel, 5-drum spindle, 6-jointed shaft, 7-spring guide, 8-pad, 9-spring, 10-centring ring, 11-earthing plate rail, 12-earthing dish, 13-mulch film.
As accompanying drawing 1,2 signals, the utility model mainly comprises earthing plate rail 11 and the earthing dish 12 that connects with roller shelves 3, earthing plate rail 11 is hinged with the afterbody of roller shelves 3 by jointed shaft 6, tail end in roller shelves 3 is provided with spring guide 7, earthing plate rail 11 is socketed on the spring guide 7, and spring guide 7 is provided with spring 9, pad and split pin; Tail end in roller shelves 3 is provided with spring guide 7 and 3 vertical connections of roller shelves; The lower end of the spring 9 that spring guide 7 is provided with places in the centring ring 10 that earthing plate rail 11 is provided with.Further describe in detail: press mold wheel 4 links by the bearing on drum spindle 5 and the roller shelves 3, and the afterbody of roller shelves 3 is by jointed shaft 6 and earthing plate rail 11 hinged linking.Spring guide 7 is fixed in the tail end of roller shelves 3, and links with earthing plate rail 11, is respectively equipped with spring 9 on the spring guide 7, pad 8, spring 9 is fixed on the spring guide 7 by pad 8 and split pin, and spring guide 7 is through in the spring 9, and the lower end places in the retainer plate 10.Earthing plate rail 11 is provided with centring ring 10, earthing dish 12, and the head end of roller shelves 3 is hinged and connected by cylinder pulling shaft 2 and frame 1.During work, frame 1 is being moved ahead by the motor vehicle traction, mulch film 13 is laid on the ground, the overlay film ditch that the film limit at mulch film 13 two ends is left the plough on the frame 1 on the ground covers, following closely press mold wheel 4 is pressed into the film limit in the overlay film ditch, earthing dish 12 is scraped the soil on film limit in the overlay film ditch, and will plant the cave and cover.Earthing dish 12 gos deep into the degree of depth on ground to be how much can realizing by the compression degree of regulating spring 9 of earthing amount, when spring 9 journey compressive states, 9 pairs of earthing plate rails 11 of spring have a downward power, power is big more, it is dark more that earthing dish 12 gos deep into the degree of depth on ground, the earthing amount is big more, is that short more its bounce of spring compression of certain-length is big more according to the spring self characteristics.
Though below design and example according to the utility model purpose have been done to elaborate with reference to accompanying drawing; but those of ordinary skills can recognize; under the precondition that does not break away from the claim limited range; still can make various improvement and conversion to the utility model, and this improvement and conversion still should belong to protection domain of the present utility model.
