Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.

Referring to fig. 1-5, the invention focuses on a cold-region paddy rice dry direct seeding machine with fertilization function, and the working principle of the machine is analyzed in detail by combining the specific structure.

The basic structure of the dry direct seeding machine is composed of two groups of frame plates 1 which are arranged in parallel, as shown in figures 1, 2 and 3. The first supporting rods 102 are firmly connected above the two groups of frame plates 1, and the supporting rods are like key spandrel girders of the equipment, not only bear the responsibility of supporting other important parts, but also play the role of connecting the parts, and are important for maintaining the stability of the equipment in the running process. The first mounting platform 3 is firmly attached at a centered position below the first support bar 102.

On the left and right sides of the first mounting platform 3, a fertilizer application module 7 is carefully provided. The fertilizer assembly 7 is comprised of two fixed plates 701, the two fixed plates 701 being tightly connected to the frame plate 1 and the first mounting platform 3, respectively, as a solid base, supporting the fertilizer box 702. The bottom of the fertilizer box 702 is in a conical design, and the structure is beneficial to natural convergence of fertilizer, so that smooth and efficient downward conveying of the fertilizer is ensured. The lower end of the inside of the fertilizer box 702 is rotationally connected with a fertilizer application roller 706 through a precision mechanical device, the upper part of the fertilizer box is rotationally connected with a rotating rod 703, and a plurality of stirring rods 704 are uniformly fixed on the outer surface of the rotating rod 703. When the equipment is operated, the stirring rod 704 continuously rotates, so that the fertilizer is effectively prevented from caking, and the smoothness of the fertilization process is ensured. The surface of the fertilizing roller 706 is provided with a plurality of accurate gaps through special design, and when the fertilizing roller 706 rotates at a constant speed, fertilizer quantitatively falls down through the gaps, so that accurate fertilization is realized. One side of the fertilizer box 702 is connected with a high-performance speed reducer 708 which is specially used for driving the fertilizer roller 706 to rotate. One end of the fertilizing roller 706 far away from the speed reducer 708 penetrates through the side wall of the fertilizer box 702 to be connected with a second driving wheel 707, one end of the rotating rod 703 far away from the speed reducer 708 also penetrates through the side wall to be connected with a first driving wheel 705, and stable power transmission is achieved through the two driving wheels through a belt. Thus, when the speed reducer 708 is started to drive the fertilizing roller 706 to rotate, the rotating rod 703 synchronously rotates through belt transmission, so that the cooperative operation of stirring and fertilizing is realized. The working principle is that the rotation speed of the fertilizer application roller 706 can be precisely controlled by precisely regulating and controlling the rotation speed of the speed reducer 708, so that the falling amount of the fertilizer can be precisely regulated. Meanwhile, the rotating speed of the stirring rod 704 is also carefully designed to ensure that the fertilizer is fully stirred in the box, prevent caking and meet the fertilizer application requirements under different soil fertility conditions.

Between the two groups of frame plates 1, rotary tillage cutters, a ditch pressing wheel 8, a soil covering wheel 9 and a soil pressing roller 16 are sequentially arranged along the working direction, and all the components can be controlled by a driving gearbox 6 in a transmission way and are cooperated with one group of driving gearboxes 6. Specifically, the rotary tillage cutter comprises two sets of rotation shafts rotatably installed between the frame plates 1, and at least three sets of rotary tillage blades 5 are firmly fixed on the outer surface of the rotation shaft and on two sides of the first installation platform 3. The bottom of the first mounting platform 3 is provided with a powerful driving gearbox 6 for driving the rotating shaft to rotate at a high speed. After the driving gearbox 6 is started, the rotary tillage blade 5 is driven by the rotating shaft to deeply rotary tillage the land, so that proper soil conditions are created for subsequent seeding and fertilizing operations. The rotary tillage cutter top is provided with the mud shield 4, and the mud shield 4 is semicircular arc platy structure, and its concave surface just to the rotary tillage cutter can not cause the influence to the fertilization in the rotary tillage operation in-process, and mud shield 4 can also effectively block the earth that splashes moreover, not only keeps the cleanness of equipment and surrounding environment, can also reduce the adhesion of earth on equipment. On the one hand, the weight of the equipment increased due to the adhesion of soil is reduced, the operation load of the equipment is reduced, the operation efficiency is improved, and on the other hand, the labor, material resources and time cost required by the later cleaning of the equipment are reduced, and the maintainability of the equipment is improved. The working principle of the rotary tillage cutter is that the gearbox 6 is driven to transmit power to the rotating shaft, the rotating shaft drives the rotary tillage blades 5 to rotate at a high speed, the sharp cutting edges of the blades are utilized to crush and loosen soil, the soil structure is improved, and the air permeability and the water retention of the soil are improved.

The pressing wheel 8 plays a key role in the whole operation flow, and a plurality of groups of pressing wheels 8 are matched with the earthing wheel 9 in a cooperative manner, so that regular and uniform ravines can be pressed on the land. The ravines not only provide accurate positioning for seeds and ensure the uniformity of sowing, but also are beneficial to gathering soil into the ditches in the soil covering process.

Two second support rods are fixedly connected to the rear sides of the two groups of frame plates 1, and a second mounting platform 11 is connected to the middle position below the two support rods. The four corners of the second mounting platform 11 are firmly connected with upright posts 12, and an air-assisted direct seeding machine collector 13 is connected above the four upright posts 12. The earthing wheel 9 is positioned below the air-assisted direct seeding machine collector 13. The working principle of the air-assisted direct seeding machine collector 13 is based on the aerodynamic principle, and a stable pressure field is formed inside the collector by high-speed air flow generated by a fan. Seeds are stored in a seed bin of the collecting and discharging device, and under the action of air flow, the seeds enter the seed conveying pipeline from the seed bin. The seed delivery pipeline is internally provided with a precise seed distribution device, and the device can precisely meter and distribute seeds according to preset sowing quantity and sowing intervals. Simultaneously, through the rotational speed of regulation fan, pressure and the flow of accurate control air current to adapt to the seed of different kinds, size and weight. For example, for seeds with larger particles and heavier weight, the rotation speed of the fan needs to be increased, the airflow pressure and flow rate are increased, the seeds can be ensured to pass through the seed conveying pipeline smoothly and accurately reach the preset sowing position, while for small and light seeds, the rotation speed of the fan needs to be reduced, the airflow parameters are accurately controlled, and the seeds are prevented from deviating from the preset position due to overlarge airflow. In addition, the collector is also provided with a sensor system, which can monitor the conveying state of seeds, such as the flow rate of the seeds, the blockage situation and the like in real time and feed back signals to the control system. The control system automatically adjusts the rotating speed of the fan or fine-adjusts the seed distribution device according to the feedback signal, so that the precision and stability of the sowing process are ensured.

In order to further improve the automatic seeding control level of the dry direct seeding machine, a radar speed measuring system is introduced. In the advancing process of the dry direct seeding machine, a radar speed measuring device arranged at the front end of the machine body monitors the traveling speed of the direct seeding machine in real time. The radar speed measurement system utilizes the Doppler effect, precisely measures the relative speed between the live broadcast machine and the surrounding environment by transmitting and receiving electromagnetic waves, and transmits speed data to the central control system in real time.

Based on the data fed back by radar speed measurement, the central control system adopts an automatic sowing control scheme, and the system stores optimal sowing quantity data of different crop seeds at different sowing speeds in advance. When the radar speed measuring device detects that the speed of the direct seeding machine changes, the central control system automatically adjusts working parameters of the seed distributing device according to a preset algorithm. For example, if the speed of the direct seeding machine is increased, the system can increase the quantity of seeds released by the seed distribution device each time in order to ensure the quantity of seeds in unit area to be consistent, otherwise, if the speed is reduced, the seed release quantity is correspondingly reduced. Thus, even and proper seeding can be realized at different running speeds. And meanwhile, according to radar speed measurement data, the central control system adjusts the working rhythm of the seed distribution device by combining with a preset sowing interval standard. For example, when the speed of the direct seeding machine is high, the system can properly shorten the time interval between two times of releasing seeds by the seed distributing device so as to ensure that the spacing between the seeds on the land meets the requirement, and when the speed is low, the time interval is prolonged so as to avoid too dense seeds. In consideration of special requirements of different crops on the sowing space, operators can input corresponding crop type information at a control system interface, and the system adjusts the sowing space control strategy accordingly to realize accurate sowing. In addition, the central control system can plan the running path of the direct seeding machine in real time by combining radar speed measurement data and a preset sowing area map. When the direct seeding machine deviates from a preset path, the system corrects the running direction of the direct seeding machine by controlling the steering mechanism according to the speed information and the current position information fed back by the radar. For example, if the speed of the direct seeding machine is high and deviates from the path, the system can increase the steering force to enable the direct seeding machine to return to the preset path as soon as possible, and if the speed is low, the direction is adjusted relatively softly, the accuracy of the driving track is ensured, and the full coverage and uniformity of the seeding area are further ensured.

When the rotating roller 14 rotates, the tapered teeth 15 are in ingenious engagement with the grooved wheel 8, so that the grooved wheel 8 is driven to work. After the ditch pressing wheel 8 finishes the ditch pressing action, the conical teeth 15 squeeze and lift the soil at the two sides of the ditch to the middle of the ditch along with the continuous rotation of the rotating roller 14, and a raised soil pile is formed at the two sides of the ditch. The soil piles have the functions of water retention and fertilizer retention, reduce the loss of water and fertilizer in ditches, protect seeds, reduce the influence of external factors on the seeds, and create favorable conditions for subsequent soil covering operation. The working principle is that the rotation of the rotating roller 14 transmits power to the grooved wheel 8 through the conical teeth 15, and the grooved wheel 8 presses out the ravines with specific shapes and intervals on the land according to the positions and the shapes of the conical teeth 15. Simultaneously, the subsequent action of the conical teeth 15 on the soil further optimizes the sowing environment, ensuring that the seeds grow under the proper soil conditions. When the seeds are transported to the set position through the seed transport pipe, the soil covering wheel 9 starts to work, and the surrounding soil is covered on the seeds through rotation or translation movement, so as to complete the soil covering operation.
