Intelligent Local Loosening and Rotating and Even Straw Covering Crop Seeder
The invention relates to the technical field of agricultural machinery and equipment, in
particular to an intelligent local loosening and rotating and even straw covering crop
seeder.
In northern China, crop will be planted after wheat harvest. Before planting crop, the
wheat straw in the field needs to be treated first, and then field is ploughed and fertilized
before sowing crop. In order to reduce people's labor and improve the speed of planting
crop, a crop seeder has been developed, which can crush the straw with purpose of
returning it to the field while sowing crop.
Chinese patent CN201410798232.6 discloses a straw crushing and cleaning no-tillage
precision crop seeder, which comprises a suspension frame, a transmission device, a
crushing device, a supporting frame, a fertilizer distributor device and a sowing device,
wherein the transmission device comprises a gearbox, a driving pulley and a driven
pulley, and the driven pulley transmits power to the crushing device which comprises a
cutter shaft with a crushing knife and a guide wheel; the front end of the shell inner wall
is provided with a bend, and the rear end of the shell inner wall is provided with a
deflector; the deflector is in the shape of a quadrangular pyramid which gradually widens
from top to bottom. Straw and wheat stubble are distributed to two sides or one side after
being crushed. Fertilization device is arranged at the back end of the supporting frame;
sowing device is arranged in the movable frame, which is arranged at the back end of the
supporting frame through a four-bar linkage mechanism. Straw crushing, cleaning, fertilization and sowing can be realized simultaneously. Straw and wheat stubble crushing can improve the sowing environment, and the sowing speed is faster and the effect is better. Sowing crop on the strip after the straw is disposed by the deflector, so that seedlings can be protected from the harm of the noctuid. However, the patent above still has the following shortcomings: firstly; in the patent above, wheat stubble and straw are crushed by the crushing device to improve the environment of the sowing field, and the crushed wheat straw is diverted to two sides or one side of the deflector by the deflector, and a vacant strip is formed under each deflector, and crop are sown on the strip. However, the crushed straw is directly returned to the field, although the straw is crushed, the total amount of straw has not changed, and the accumulated area of straw is smaller after being separated by the deflector. The amount of straw accumulated on both sides of the strip is too large, which makes the straw not easy to decay, so that it can't play a role in returning fertilizer to the field. Moreover, the accumulation of straw can easily provide breeding places for pests and bring trouble to crop growth; Secondly, there is no automatic detection and warning device in the patent above. For example, the straw collecting device is not provided with sensing equipment, and if the straw collecting device is stuck and other conditions cannot be found and solved in time, the equipment will be seriously damaged. There is also no detection device in the sowing mechanism, and once the sowing mechanism fails to sow, the driver can't find it in time, resulting in sowing failure.
The purpose of the invention is to provide an intelligent local loosening and rotating and
even straw covering crop seeder, which solves the technical problems in the prior art that straw can't be effectively disposed and the automatic monitoring degree in equipment is low.

Compared with the prior art, the invention has the beneficial effects that:
Firstly, the collecting shaft is driven to rotate by the collecting motor, and the collecting
shaft drives the flail knife to rotate to scatter the straw to the auger, and at the same time
crush the straw. The crushed straw is transported by the packing auger and blown by the blower, and scattered to the straw scattering mechanism through the discharge channel for collection. When the packing auger carries out transport in the housing, the condition in the collecting cavity is monitored by the pressure sensor in real time. If the quantity of straw in the collecting cavity is too large, the straw will exert great pressure on the detection plate. The pressure of straw in the collection cavity can be detected through the collision between the pressure sensor and the detection plate. When the pressure is greater than a certain value, it means that there are excessive straw in the collection cavity, which will cause the collecting and crushing assembly to be stuck, thus reminding users to carry out detection and maintenance in time. At the same time, the controller controls the electromagnetic bolt to open, so that the detection gate is opened, thus relieving the pressure in the collection cavity and avoiding excessive damage to equipment. The problem that the straw collecting mechanism can't be found damaged in time in the prior art is solved, and the user can be reminded of the equipment damage in time, so that the equipment can be repaired in time, and excessive damage caused by continuous use of the equipment after damage is avoided.
Secondly, seeds in the seed containers are seeded by the seed metering device, and the
seed fall into the field through the sowing tube. In the process of sowing seeds, the
grating sensors will sense signals. If the signal interval time of the grating sensors is
incorrect, it indicates that there is a problem with the sowing assembly. The cameras are
set to shoot the sowing state, and the display directly displays to facilitate users to watch
the seeding state so that the problems during sowing can be found in time. The
arrangement of the cameras, the display screen and the grating sensors further improves
the intelligence of the invention, so that a user can grasp the working condition of the sowing assembly in time, and if the sowing assembly fails, users can detect and repair in time to avoid excessive damage to equipment.
Thirdly, the straw collected by the collecting and crushing assembly can be stored in the
straw receiving box; the material spreading shaft is driven to rotate by spreading motor,
and the pushing teeth on the material spreading shaft push the straw in the straw receiving
box to be discharged through the discharge ports; each discharge port corresponds to a
ridge, so that the straw are all scattered on the ridge so as to avoid excessive
accumulation of straw on the ridge, which is beneficial to the rapid decay of straw, and
can also avoid excessive accumulation of straw to provide growth conditions for pests;
and the remaining straw are also convenient for centralized disposal through straw
receiving box, thus solving the problem of damage to seeds caused resulted from direct
return of straw in the prior art.
Fourthly, during cultivation and sowing, the rotary tillage motor drives the rotary tillage
shaft to rotate, and the rotary tillage shaft drives the rotary blades to rotate for rotary
tillage. The interval arrangement of several sets of rotary blades makes the rotary blades
only carry out rotary tillage on local areas of the field, and no tillage is carried out on the
fields between adjacent rotary blade at two sides to prevent excessive evaporation of soil
moisture, etc.; after that, furrows appear in the rotary tillage area of the rotary blades
through a furrower; and after that, the scarification piece is located at the bottom of the
furrows and moves along with the movement of the vehicle. During the moving process,
both sides of the scarification piece extend to the lower end of the ridge in the middle of
the adjacent furrows, thus scarifying the deep part of the ridge. The interval rotary tillage
can allow the surface of the ridge zero-tillage, prevent the excessive evaporation of soil moisture, and the middle rotary tillage is beneficial to the rooting and germination of seeds. Deep scarification is beneficial to rooting. Compared with the prior art, it can effectively promote the growth of seeds and play a certain role in protecting fields.
Fifthly, the vehicle in this invention can adopt a tractor with considerable power
purchased from the market, which increases the feasibility and is easy to popularize.
