Problems solved by technology

However, the wheat straw scattered on the field by the wheat harvester after harvesting the wheat is unevenly distributed, forming agglomerates and forming rows, which is easy to block the columbine legs and cause seedling shortage. It also often causes the soil cover to be not dense enough to cause the seeds to hang in the air and affect the emergence of seedlings.

Embodiment 1

[0037] Such as figure 1 As shown, a straw throwing and seeding integrated machine capable of biological mulching includes a vehicle body 1, and a straw picking unit 2, a conveying unit 3, a cutting unit 4, and a buffer throwing unit are arranged on the vehicle body 1 in sequence from front to back 5. A seeding unit 6 is provided between the straw picking unit 2 and the buffer throwing unit 5 and below the cutting unit 4 . The sowing unit 6 can be a sowing device in the prior art, and will not be repeated here.

[0038] Such as figure 2 with image 3 As shown, the straw picking unit 2 includes a collecting bucket 21 in the shape of a bulldozing shovel, and the inside of the collecting bucket 21 is provided with a conveying auger 23, and the two ends of the conveying auger 23 are connected to the The collection bucket 21 is connected in rotation, and one end of the conveying auger 23 is connected with the power unit of the vehicle main body 1 through a transmission mechanism...

Embodiment 2

[0049] Since the first cutter 4411 tends to become blunt during the working process, in order to ensure the cutting effect, it needs to be replaced in time. In order to reduce maintenance costs and improve maintenance efficiency, the first cutter 4411 and the first cutting roller 441 A split structure is adopted between, the first cutter 4411 is provided with a T-shaped slider, and the first cutting roller 441 is provided with a T-shaped chute matching the T-shaped slider.

Embodiment 3

[0051] Such as Figure 9 with Figure 11 As shown, the cutting unit 4 includes a cutting box 46, in which a set of conveying rollers and a cutting mechanism are sequentially arranged from front to back, and the cutting mechanism includes a second cutter 452. Both ends of the second cutter 452 are fixedly connected to the piston rod of the second oil cylinder 451 respectively, and the cylinder body of the second oil cylinder 451 is fixedly arranged on the cutting box 46 . A fixed cutting plate 453 matched with the second cutting knife 452 is arranged below the second cutting knife 452 , and the fixed cutting plate 453 is fixedly arranged on the cutting box 46 .

[0052] Further, in order to ensure that the straw can be smoothly transported between the second cutter 452 and the fixed cutting plate 453, to avoid falling, as Figure 10 As shown, the end of the fixed cutting plate 453 close to the conveying roller set is in the shape of an arc coaxially arranged with the second c...

Abstract

The invention discloses a straw throwing and sowing integrated machine capable of realizing biological coverage. The integrated machine includes a vehicle body, a straw picking unit, a conveying unit, a cutting unit, and a buffer throwing unit. A seeding unit is arranged below the cutting unit. The straw picking unit includes a collecting hopper, a conveying auger and a mowing wheel arranged inside the collecting hopper, and a straw feeding port connected to the conveying unit is arranged on one side of the collecting hopper. The cutting unit includes a cutting box, and a conveying roller set and a cutting roller set are arranged in the cutting box. The buffer throwing unit includes a buffer box communicated with the cutting unit, the side of the buffer box is provided with a buffer box outlet, and the buffer box outlet is connected to the throwing pipeline through an induced draft fan. The all-in-one machine not only ensures the quality of corn sowing, reduces surface transpiration, and inhibits the growth of weeds, but also reduces the rising force of salt when used in saline-alkali soil conditions, alleviates salt stress, and promotes crop growth.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a straw throwing and sowing integrated machine capable of realizing biological coverage. Background technique [0002] Biological mulching is a new cultivation technology that uses crop straw and other vegetation to cover the ground to store water and moisture, suppress weeds, improve soil aggregate structure and rhizosphere microbial community. [0003] At present, in the wheat and corn double-cropping areas of Huanghuaihai, when sowing summer corn, it is generally used to direct seeding with stubble, that is, after the wheat is harvested, the land is not plowed, and the corn is directly sown. However, the wheat straw scattered on the field by the wheat harvester after harvesting the wheat is unevenly distributed, agglomerated and formed into rows, which is easy to block the columbine legs and cause seedling shortage, and often causes the soil cover to be not den...
