A seed leading pipe is connected with a seed box and a shell of the seed sowing device, a guide plate is positioned at the frontage of the lower part of the seed leading pipe and supported by a pressure spring, and an adjusting plate is arranged at the backside of the entrance part of the shell of the seed sowing device; a seed sowing plate valve is arranged at the frontage of the entrance part of the shell of the seed sowing device and to keep a horizontal position through a plate valve torsion spring; a latch torsion spring drives a locating latch, the opening and the closing of the seed sowing plate valve are controlled by an opening cam, and seed sowing wheels and the opening cam are fixed on a seed sowing wheel shaft; the seed sowing operation can be realized exactly, rapidly, and without damaging potato seeds through the movement of the seed sowing plate valve, and thus, the utility model has the advantages of simple structure, small size, convenient adjustment, and stable operation.
Description
The utility model is the supporting seeding unit of a kind of sower, particularly a kind of plate valve formula seeding unit of potato sowing.
Seeding unit is the main working parts of sower, be configured at the bottom of the seed-box or the side-wall type case in.Forms such as seeding unit commonly used divides by structure grooved pulley type, type cellular type, centrifugal, pneumatic type have seeding units such as wheat, corn, soybean, cotton by the purposes branch; What the plantation of potato was adopted is block potato kind, generally use elevator chain bale-out kind feed mechanism (chief editor of Zhenjiang agricultural machinery institute. agricultural mechanics. Beijing. Chinese agriculture machinery publishing house, 1981; Han Jianqiang. small-sized potato culture series mechanical. rural area mechanization, 1998, (1): 29; Yan Qingyun. " marathon " potato tuber planter. Shanxi agricultural machinery, 1993, (2): 19; Wang Guangsheng, Wang Yuzhong, the research of Fan Wen constitution .2BXSM-1B type potato combined seed and fertilizer drill. agricultural machinery and food machinery, 1999, (3): 15～17; In ripple, the development of the few outstanding .2CM-2 type potato setter of merchant. the mechanization of pastoral area, rural area, 1998, (3): 30).The all kinds seeding unit that adopts all is that seed class planting seed is used now, does not also have to sow the seeding unit of block potato kind; In the plantation of potato, the feed mechanism complex structure of elevator chain bale-out kind, bulky, the parts ratio is easier to collsion damage potato kind at the volley, and is got the restriction of kind of mode, is easy to generate the phenomenon of broadcast leakage.
The objective of the invention is to design a kind of and the supporting plate valve formula seeding unit of Sowing machine for potatoes, can accurately, fast, damage potato kind ground and do not carry out seeding operation, and simple in structure, volume is little, easy to adjust, working stability.
The plate valve formula seeding unit of a kind of potato sowing of the present utility model is dredged pipe, adjustment plate, slideway, adjustment screw, opening cam, seed wheel, seed shaft, sow mouth, seeding unit shell, positioning engine, sincere sub-torsion spring, plate valve torsion spring, seed arrangement plate valve, stage clip, guide plate, seed-box etc. by seed and is formed.Seed is dredged pipe opening suitable for reading and at the bottom of the seed-box and is connected, and end opening is fixed on the seed import position of seeding unit cover top portion, and guide plate is installed in seed and dredges the anterior position of managing the bottom, by stage clip with its jack-up; Adjust the rear, seed import position that plate is arranged on the seeding unit cover top portion, fix with the adjustment screw along the size back that slideway is adjusted the seed import according to the specification of block potato kind; Seed arrangement plate valve is installed in the place ahead, seed import position of seeding unit cover top portion, makes it keep horizontal level by the plate valve torsion spring, and positioning engine is driven in the locating slot that make it top be stuck in seed arrangement plate valve by sincere sub-torsion spring, the open and close of control seed arrangement plate valve; Be installed on the seed shaft after seed wheel and the opening cam combination, be fixed in the seeding unit shell by seed shaft.
When the block seed of potato continuously by the seed-box bottom opening when seed is dredged the downslide suitable for reading of pipe, be subjected to slight thrust by stage clip jack-up guide plate, being close to seed dredges the rear wall of pipe and continues to slide into down the control mouth of adjusting plate and seed arrangement plate valve composition and stop, seed shaft drives seed wheel and opening cam rotates, when the salient point of opening cam turns to positioning engine it is pushed aside, the locating slot of the top and seed arrangement plate valve of positioning engine breaks away from, seed arrangement plate valve is out of hand and open when the block seed of potato presses down, and the block seed of potato just falls in the seed wheel; At this moment seed arrangement plate valve is utilizing the space that falls between two block seeds to reset rapidly under the effect of torsion spring, make seeding board keep horizontal level in sincere sub-torsion spring drives positioning engine the top locating slot that is stuck in seed arrangement plate valve immediately, stop the block seed of next piece potato to glide and fall in the seed wheel.Seed shaft drives seed wheel and opening cam is rotated further, when the salient point of opening cam turns to positioning engine again it is pushed aside, the locating slot of the top and seed arrangement plate valve of positioning engine breaks away from, the seed arrangement plate valve block seed potato out of hand opens when pressing down, the block seed of another potato falls in the seed wheel, seed arrangement plate valve is utilizing the space that falls between two block seeds to reset rapidly again under the effect of torsion spring, make it keep horizontal level in sincere sub-torsion spring drives positioning engine the top locating slot that is stuck in seed arrangement plate valve immediately, stop the block seed downslide of next piece potato to fall in the seed wheel, the block seed of the potato that falls freely falls when going to sowing mouthful of seeding unit shell with seed wheel, go round and begin again, finish the seeding operation of potato.
Plate valve formula seeding unit of the present utility model can be adjusted the spacing of seeding by adjusting the rotating speed that changes seed shaft, to satisfy the different technologies requirement of block planting seed agronomy such as potato.
The advantage of the plate valve formula seeding unit of a kind of potato sowing of the present utility model is: adopt plate valve to control the spacing in the rows of seeding unit sowing, be suitable for the sowing of block potato kind, have and accurately, fast, damage the characteristics that potato kind ground does not carry out seeding operation, and simple in structure, volume is little, easy to adjust, working stability.
Below in conjunction with drawings and Examples the utility model is further specified.
