Description

Drill coulter for wheat

The utility model relates to a kind of agricultural machinery, specifically is the no-tillage trench digging drilling machine of a kind of wheat class.

The by artificial seeding of traditional wheat crops need turn over earlier, digs pit then, sowing, blinding four procedures altogether just can be finished, and wastes time and energy, though sower is arranged now, but still need turn over earlier, work efficiency is not high, and the seed ontogeny of especially sowing is bad, it is irregular to emerge, the percentage of earbearing tiller is not high, and its reason is that seed is directly broadcast in heatable adobe sleeping platform, in case of overcast and rainy, soil compaction, seed is immersed in the ponding, easily causes mashed kind, as continuous sunny, the seed germination that can not absorb water, postponed the period of emerging, existing ox is ploughed the plough sowing, though be drilling, but original backwardness can not satisfy the needs that modern agriculture is produced.

The purpose of this utility model just provides a kind of agronomy and combines with agricultural machinery, carries out a kind of wheat class sowing machine of no-tillage drilling in the rice field that gathered in the crops, and the work efficiency height can be embraced season, and seed development is good, percentage of earbearing tiller height.

Solution of the present utility model is: be made up of frame, seeding part and trench digging part, wherein seeding partly is by feed shaft, seeding unit and seed-storage box constitute, above-mentioned seeding part is contained on the support by the seed-storage box support, on the frame under the seeding unit, discharging tube is housed, the trench digging colter is equipped with in the place ahead at the outlet spout of discharging tube, the rear is equipped with arc and is covered native plate, bogie wheel and land wheel are housed on support, on the axle of land wheel, drive sprocket is housed, by chain be packed in feed shaft on be connected by movable sprocket, its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, Fig. 2, the no-tillage trench digging drilling machine of wheat class of the present utility model is by frame (1), seeding part and trench digging part are formed, wherein seeding partly is by feed shaft (9), seeding unit (10) and seed-storage box (11) constitute, be prior art, above-mentioned seeding partly installs on the support (1) by seed-storage box support (12), on the frame (1) under the seeding unit (10), discharging tube (3) is housed, trench digging colter (4) is equipped with in discharging opening the place ahead of discharging tube (3), the rear is equipped with arc and is covered native plate (23), feed shaft (9) rotates, driving seeding unit (10) discharges the seed in the seed-storage box (11), fall in the discharging tube (3), and enter in the ditch that colter leaves from discharging opening, covering native plate (23) subsequently will be piled up in loosening the soil of ditch both sides and cover on the seed in the ditch, bogie wheel (6) and land wheel (24) are housed on support (1), supported whole drilling machine, wherein land wheel (24) still is the power resources of feed shaft (9), on the axle (25) of land wheel (24), drive sprocket (7) is housed, by chain (14) be packed in feed shaft (9) on be connected by movable sprocket (8), land wheel (24) rotates, driving drive sprocket (7) rotates, rotated by movable sprocket (8) by chain (14) drive, rotate thereby drive feed shaft (9), make seeding unit (10) work.On discharging tube of the present utility model (3), be fixed with lifter plate (22), be fixed with lifting axle sleeve (16) on the lifter plate (22), lifting axle sleeve (16) is enclosed within on the lifting shaft (15) that is connected on the frame (1), make lifting axle sleeve (16) go up motion at lifting shaft (15), be that discharging tube (3) can move up and down, thereby regulate the trench depth that colter (4) is opened, on discharging tube (3) and frame (1), be hinged with the hinged connecting rod (20) of an end and lifter drawing bar (19) respectively, push away when on lifter drawing bar (19), applying, during pulling force, move up and down by connecting rod (20) the driving discharging tube (3) that is hinged on the discharging tube (3), thus the lifting of realization colter (4).Traction is housed on frame (1) closes (5), be used for connecting with the draw bar (18) of ploughing and leveling machine for paddy field, like this, the utility model is to be traction power with the ploughing and leveling machine for paddy field on the one hand, the ploughing and leveling machine for paddy field motion, just drive the utility model motion, thereby make drilling machine work, also enlarged the function of ploughing and leveling machine for paddy field on the other hand.

The no-tillage trench digging drilling machine of the wheat class that the utility model provides is the new technology that a kind of agronomy combines with agricultural machinery, can in the rice field that gathered in the crops, carry out no-tillage water furrow planting, the work efficiency height, can embrace season, the wheat seeds of sowing through this drilling machine both can fully absorb soil moisture, can not be immersed in the puddle again, cause mashed kind, therefore ontogeny is good, it is neat to emerge, and tillering ability is strong, percentage of earbearing tiller height, effective fringe of unit are increases, not only be suitable for the flat area use but also be suitable for the mountain area and the knob use, this drilling machine also is applicable to the no-tillage drilling operation of diameter less than 10 millimeters granular seeds, with the supporting use of ploughing and leveling machine for paddy field, enlarged the function of use of harvesting and tillage machine, very big promotional value has been arranged.

Accompanying drawing has been represented specific embodiments of the present utility model.

At first accompanying drawing is described:

Fig. 1 represents Facad structure schematic diagram of the present utility model;

Fig. 2 represents side view of the present utility model.

According to embodiment shown in the drawings, further structure of the present utility model is that frame (1) upward is equipped with the regulating handle (13) that connects with seeding unit (10) by journal stirrup (17), be used for regulating the size of amount of seed metering, connecting rod (20) connects with discharging tube (3) by journal stirrup (21), and promptly journal stirrup (21) is welded on the journal stirrup (21).Six seeding units (10) are housed on frame (1) altogether, and corresponding also has six discharging tubes (3), colter (4) and covers native plate (23).
