Mulch film spreading and seeding machine
Technical field
The utility model is a kind of agricultural tool, i.e. the mulch film spreading and seeding machine of dry field farming thing such as a kind of corn.
Background technology
Plastic mulching is a kind of proportion of crop planting technology of popularizing in recent years, and it to the effect that utilizes plastic film that ground is covered, at the punching place growth crop plant of film.This method can reduce the evaporation of moisture and the loss of fertility, can increase ground temperature, eliminates weeds, and sowing in advance prolongs the breeding time of crop.Though increased some costs, the advantages outweigh the disadvantages, meet the agricultural development direction, promotion rate is very fast.Not only adopted, even field crops such as corn also begin to adopt by the higher economic crops of added value.The plastic mulching workload is big, is pressed for time, and needs to adopt mechanical work., using more film-laying machine at present is that film on the ground, function ratio is more single between advancing by hitch frame traction film spool, can not once finish a complete set of operation.In recent years release the facility that can once finish fertilising, shop film and seeding operation, but operation quality is poor, efficient is low, and the fault rate height is higher to the smooth conditional request in field.
Summary of the invention
The purpose of this utility model provides a kind ofly can once finish trench digging, fertilising, shop film, seeding operation, and operation quality is good, efficient is high, stable performance, to the not high mulch film spreading and seeding machine of the smooth conditional request in field.
Above-mentioned purpose is realized by following technical scheme: developing a kind of mulch film spreading and seeding machine, also is to be made of hitch frame, plough, land wheel, fertile case, film spool, seeding unit etc., and different is: a leg-of-mutton scraper plate is arranged in the front of facility; Hitch frame is contained on the crossbeam of frame front by sliding sleeve, and the lateral attitude is adjustable; Land wheel is a cage cylinder that is surrounded by many reinforcing bars.
The fertilizer mechanism of the fertile case of said land wheel top is the fertilizer fertilizer mechanism.
The fertilizer mechanism of the fertile case of said land wheel top is the chemical fertilizer fertilizer mechanism.
Said seeding unit in film spool back has a kind case that circle is box-like, and planting the case periphery has platen, plants case uniform duck-beak type punching seeding unit all around.
In said seeding unit back, both sides respectively are provided with a slice blade formula banker, in the middle of two bankers, are provided with two breast boardss.
The beneficial effects of the utility model are: once finish operations such as smooth, trench digging, fertilising, shop film, sowing, lower to the smooth conditional request in field, operation quality is good, efficient is high, stable performance, can be competent at the mulch sowing operation of various crop such as corn, soybean, peanut, capsicum, cotton.And have characteristics such as simple in structure, with low cost, sturdy and durable, thereby have good market prospects.

Among the figure as seen: hitch frame 1, arm-tie 2, scraper plate 3, plough 4, land wheel 5, film spool 6, seeding unit 7, breast boards 8, banker 9, back arm-tie 10, pull bar 11, driving-chain 12, fertile case 13, towing plate 14, leading screw 15, sliding sleeve 16, crossbeam 17, reinforcing bar 18, platen 19 is planted case 20, seeding unit 21, pressing plate 22, spring 23.
Embodiment
Fig. 1,2 has introduced a kind of embodiment.As shown in the figure, this facility are a kind of once mulch film spreading and seeding machines of two row, and there is a hitch frame 1 its front, and arm-tie 2 is stretched out at hitch frame 1 two backward, and scraper plate 3, plough 4, land wheel 5, film spool 6 are housed successively.Connect back arm-tie 10 more backward, seeding unit 7, breast boards 8, banker 9 are housed, pull bar 11 tensions are arranged between the hitch frame 1 of back arm-tie 10 and front, and the axle head of land wheel 5 has sprocket wheel upwards to drive fertile case 13 fertilizers by driving-chain 12, and fertilizer is delivered to the back of plough 4 by defertilizing tube.During work, at first one of film is pressed, in traveling process, film on the ground, and by banker 9 in both sides ridgings, middle breast boards can prevent that soil from falling the middle part.
By Fig. 3,4 as seen, said scraper plate 3 is the delta-shaped members that are made of two sections angle steel.Be contained in the front, further ground grading is for the operation of back provides good conditions.
By Fig. 5,6,7 as seen, said hitch frame 1 is to be enclosed within on the crossbeam 17 of hitch frame 1 by sliding sleeve 16 by two relative towing plates 14, the screwed pipe of band screw is arranged at sliding sleeve 16 tops, the inside is fitted with a leading screw 15, and an end of leading screw 15 has handle, and the moving handle can drive sliding sleeve 16 left and right sides translations, even hitch frame 1 is displaced sideways, make facility be in a side of tractor, its effect is that facility can be near Chi Geng when walking, and can dwindle the distance between sown scope.
Shown in Fig. 8,9, land wheel 5 is cylinders of the squirrel-cage that surrounded by a plurality of reinforcing bars 18, is the power wheel of these facility fertilizer mechanism.Go up on reinforcing bar 18 surfaces among the figure also has striped, and purpose is to obtain bigger frictional force.This land wheel 5 is contained in the back of plough, both can prevent to skid, and has hack function preferably again, for the shop film and the protective film of back plays a role.In addition,, can be fertilizer mechanism bigger power is provided, thereby can be used for the discharging of fertilizer, can certainly drive the discharging of chemical fertilizer because the ground ability of grabbing of this land wheel 5 is stronger.
Figure 10,11 has introduced a kind of seeding unit 7.The kind case 20 of this seeding unit 7 is round boxs, one circle platen 19 is arranged on every side, plant case 20 uniform several seeding units 21 on every side, seeding unit 21 adopts the duck-beak type seeding unit, a cavity that can advance as seed is arranged in kind of case, case stretches out a sharp mouth outward, and there is long pressing plate 22 sharp foremost, and pressing plate 22 fronts are provided with spring 23.In rotation, the seeding unit 21 of kiss the earth sharp mouth when puncturing film, pressing plate 22 is pressed and is driven duckbilled and open, the seed of the inside spreads in the hole just, continues to advance again, the duckbilled of this seeding unit is closed, and the upwards operation of several seeds of splendid attire.Another seeding unit carries out seeding.
