Description

Technical Field

[0001] The present invention relates to the technical field of agricultural improvement, and in particular to agricultural equipment used for agricultural soil improvement. Background Art

[0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture is a basic industry that provides support for national economic construction and development. With the rapid development of economy and science and technology, the emission of pollutants continues to increase. In addition, with the increasing use of pesticides and fertilizers in agricultural production, soil pollution is becoming more and more serious, which in turn leads to worse soil performance. Therefore, it is necessary to improve the soil. Soil improvement is the use of agricultural technical measures to improve the soil. Traditional agricultural soil improvement equipment has many defects. In terms of salt response, it lacks real-time monitoring capabilities and can only rely on manual sampling, which makes it difficult to effectively respond to changes in soil salinity, resulting in low desalination efficiency. In terms of the operation process, operations such as turning over the soil, crushing, and fertilizing are separated from each other and carried out step by step, and the operation efficiency is extremely low. The energy consumption control is unreasonable, and a fixed power output is used, resulting in high no-load losses and energy waste. Moreover, the equipment needs to frequently clean the soil adhered to the blade during use, which not only increases the maintenance workload, but may also affect the normal operation of the equipment due to untimely maintenance, resulting in high overall maintenance costs.

[0005] In a possible implementation, the left and right ends of the fourth rotating shaft are respectively rotatably connected in two fixed rods, and the cleaning soft brush abuts against the outside of the corresponding scraper.

[0006] In a possible implementation, a plurality of slide grooves are provided outside the fixed cylinder, and the scraper penetrates and is slidably connected in the corresponding slide grooves.

[0007] In a possible implementation, four support rods are fixedly connected to the right side of the fixed cylinder, and ends of the four support rods that are away from each other are fixedly connected to pulleys, and the four pulleys are slidably connected in the same fixed cover.

[0008] In a possible implementation, limiting holes are provided in the two fixing rods, and the limiting posts penetrate through and are slidably connected in the corresponding limiting holes.

The speed and direction of the second motor are dynamically adjusted by the control unit based on the salt data. The control unit has a built-in PID algorithm, and the blade depth is matched with a preset salt-depth mapping table by adjusting the rotation angle of the third shaft.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are: 1. The multi-channel salt sensor array is installed behind the blade to directly contact the tilled soil and obtain the conductivity (EC value) data in real time. The control unit (PLC) has a built-in PID algorithm, combined with the preset salt-depth mapping table, to dynamically adjust the blade's exploration depth and the speed of the second motor. In saline-alkali land operations, the equipment can automatically identify high-salt areas (EC>4dS / m), deepen the blade to turn the soil to less than 40cm, and replace the deep low-salt soil to the surface, thereby increasing the desalination efficiency by 60%-80% (traditional equipment only relies on a fixed depth, with a desalination rate of about 30%). It can also dynamically adjust the speed to reduce the no-load energy consumption of the second motor, reducing the overall energy consumption by 25%.

[0013] 2. The tilling component drives the blade to rotate and till the soil through the rotating disk. The crushing component uses the cam to impact the crushing cone to crush the hard soil blocks. The cleaning component drives the soft brush to remove the soil stuck to the blade through the reciprocating screw. The unloading component feeds accurately: the drum slot is linked with the discharge port of the storage box to ensure that the amount of improver (such as gypsum, organic fertilizer) is matched with the tilling speed, so that the equipment can complete the whole process of tilling, crushing, applying improver and cleaning in one operation, with an operating efficiency of 3-5 mu / hour (traditional equipment needs to be operated in steps, with an efficiency of ≤1.5 mu / hour). The synergistic effect of the crushing cone and the blade makes the soil block particle size <2cm, directly generating a fine and broken soil layer suitable for sowing, reducing the subsequent raking operation by 70% compared with traditional equipment (particle size>5cm).

[0014] 3. The moving trajectory of the blade is constrained by the fixed cylinder slide, and the support rod pulley slides in the fixed cover to ensure the stability of the structure under high load. The limit column slides in the limit hole of the fixed rod to prevent the crushing component from shifting due to excessive soil resistance. When the equipment is operating in hard soil (compactness>200kPa), the amplitude of the crushing cone is automatically increased, and the crushing efficiency is increased by 40% compared with the traditional fixed amplitude design. The cleaning soft brush cleans synchronously with the movement of the blade to reduce the torque loss caused by clay, thereby extending the motor life by 30%. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Salt-depth mapping relationship The equipment solves the pain points of traditional agricultural machinery, which has single functions and relies on experience-based operation, through the closed loop of salt perception, intelligent decision-making and precise execution. Its core advantages are as follows: Precision: Dynamic adjustment based on soil parameters to avoid waste of resources; Efficiency: Multi-function collaboration reduces operation links and improves efficiency by 2-3 times; Intelligence: Reduce the skill requirements for operators and adapt to the needs of large-scale precision agriculture.

[0029] The working principle of the present invention is as follows: the device is convenient for operators to use through the operating rod on the top of the base 1, the top of the base 1 is provided with a guide wheel, and the bottoms of the two fixed rods 4 are fixedly connected with electric drive wheels 39, so as to realize the movement of the device in the farmland, and facilitate the improvement of soil in different areas; The storage box 2 is used to store materials required for improving the soil. The materials are added from the feed port 38 at the top of the storage box 2. When the first motor 6 is started, it drives the first rotating shaft 7 to rotate, and the drum 8 fixed on the first rotating shaft 7 rotates accordingly. The plurality of slots 9 outside the drum 8 rotate with the drum 8. When the slots 9 rotate to communicate with the discharge port 37 at the bottom of the storage box 2, the materials in the storage box 2 will fall into the slots 9 and be brought out with the rotation of the drum 8, so as to realize quantitative discharge of the materials and sprinkle them on the soil that needs to be improved. At the same time, the first rotating shaft 7 drives the driving wheel 10 to rotate, and the driving wheel 10 drives the driven wheel 11 to rotate through the anti-slip conveyor belt, so that the second rotating shaft 12 fixedly connected to the driven wheel 11 rotates, providing power for the soil turning component; The rotation of the second rotating shaft 12 drives the fixed cylinder 14 and the corresponding four supporting rods 34 and the pulley 35 to rotate in the fixed cover 5, further enhancing the stability of the movement of the soil turning assembly; The first gear 13 on the first rotating shaft 7 rotates, driving the second gear 21 meshing therewith to rotate, thereby causing the fourth rotating shaft 22 fixed in the second gear 21 to rotate, and the two cams 23 fixedly connected to the outside of the fourth rotating shaft 22 rotate along with the fourth rotating shaft 22, and the raised part of the cam 23 will lift the moving frame 24, so that the limiting column 25 at the bottom of the moving frame 24 slides back and forth in the limiting hole 36 in the fixed rod 4 to ensure the vertical movement of the moving frame 24, and the moving plates 26 fixedly connected to the bottom of the two moving frames 24 will move along with the up and down movement of the moving frames 24, and the multiple crushing cones 27 at the bottom of the moving plates 26 will crush the turned-up soil to make the soil looser, which is conducive to improving the mixing of materials and soil; When the fourth rotating shaft 22 rotates, the reciprocating screw 28 on it also rotates. The fixed column 29 and the fixed sleeve 30 slidably connected to the outside of the reciprocating screw 28 make reciprocating linear motion under the action of the reciprocating screw 28. The cleaning soft brush 32 at the rear end of the limit rod 31 at the top of the fixed column 29 will slide on the surface of the blade 20 with the movement of the fixed column 29, cleaning the blade 20 to prevent soil from adhering to the blade 20 and affecting the soil turning effect. The front end of the limit rod 31 is slidably connected to the limit groove 3 on the rear side of the storage box 2, further ensuring the stability of the movement of the cleaning soft brush 32; The multi-channel salt sensor array behind the blade 20 detects the conductivity data of the soil in real time, and transmits the data to the programmable logic controller (PLC) in the control unit through a wireless transmission module (such as LoRa) or a waterproof cable. The signal processing module filters and calibrates the salt sensor data to eliminate interference such as mechanical vibration to ensure the accuracy of the data. The depth control algorithm dynamically adjusts the penetration depth of the blade 20 based on the preset salt threshold. The motor drive interface forms a closed-loop control with the second motor 15. The control unit has a built-in PID algorithm to dynamically adjust the speed and direction of the second motor 15 according to the salt data. By adjusting the rotation angle of the third rotating shaft 16, when the second motor 15 is started, the third rotating shaft 16 is driven to rotate. The two rotating disks 17 on the third rotating shaft 16 rotate accordingly, and the arc groove 18 opened outside the rotating disk 17 causes the moving column 19 and multiple blades 20 connected therein to move outward to a suitable distance in the slide groove 33, and makes the depth of the blade 20 match the preset salt depth mapping table, and then the soil can be turned over to achieve precise soil improvement operations and improve the improvement effect.

[0030] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
