Description

Technical Field

[0001] This invention relates to the field of agricultural planting machinery and equipment technology, and in particular to a soil-turning device for agricultural planting. Background Technology

[0002] In the early stages of crop planting, tilling is one of the core processes. Its function is to loosen the soil, break up the compacted layer, and facilitate the even mixing of herbicides, pesticides, or base fertilizers with the soil, thus providing a good soil environment for crop sowing and growth.

[0003] In practical applications, existing tillage equipment has begun to integrate spraying structures, but several technical defects remain: First, the material mixing mechanism mostly uses a single-shaft straight rod mixer, resulting in a single mixing path, poor mixing uniformity, and problems such as pesticide sedimentation and uneven concentration. This can affect the effectiveness of the equipment or even cause localized soil damage. Second, the spray nozzles are mostly fixed, resulting in a narrow spraying range and insufficient coverage, easily creating blind spots or localized overspraying, leading to low material utilization. Third, the tillage rollers are mostly fixed-width structures, making it impossible to flexibly adjust the tillage width according to different planting row spacings and plot sizes, resulting in poor equipment versatility. Fourth, the overall structural layout is not reasonable enough, and the supporting components that carry the mixing tank lack stability. Long-term operation in the field can easily lead to loose connections and deformation, affecting the service life and operational reliability of the equipment, which is detrimental to practical application and operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) This invention adopts a dual-motion stirring structure with a rotating disk revolving around a gear and a toothed groove meshing and rotating, which drives the mixing roller to stir the material in the mixing tank in multiple dimensions. Compared with traditional single-shaft stirring, it can effectively avoid material sedimentation and stratification, ensure the uniform mixing concentration of herbicides, insecticides or fertilizers, prevent local high concentrations from burning seedlings or low concentrations from causing failure, and greatly improve the stability and consistency of application effect. Through the swing mechanism composed of a turntable, slider, chute and swing rod, the nozzle can realize reciprocating swing spraying. With the stable pressurization of the pressure pump, the horizontal spraying coverage can be expanded, avoiding spraying blind spots or local over-spraying. At the same time, the swing spraying can make the material fall evenly on the soil surface, significantly reducing material volatilization and loss, and improving fertilizer and pesticide utilization.

[0019] (2) The present invention drives the expansion cover to rotate relative to the protective cover by a hydraulic rod, which can quickly adjust the expansion range of the expansion roller, thereby realizing stepless adjustment of the width of the tillage operation. It can adapt to different crop planting row spacing, different plot sizes and different tillage needs. It can meet a variety of field operation scenarios without changing the implements, and the equipment's versatility and practicality are significantly improved. The mixing spraying structure and the tillage structure are integrated into the same vehicle body to realize continuous synchronous operation of "mixing, spraying and tillage", eliminating the separate operation process of separate spraying and tillage, reducing the number of trips in the field, shortening the operation time, and improving the overall efficiency of pre-planting land preparation. At the same time, tillage can quickly bury the surface material into the soil, improve the combination effect of fertilizer and pesticide with the soil, and make it more conducive to crop absorption.

[0020] (3) The present invention strengthens the support between the base plate and the vehicle body by means of diagonal bracing, which can effectively disperse the load of the mixing tank and the spraying mechanism and avoid structural deformation during long-term operation; the rotary tiller and the extension roller are connected by a snap-fit ​​joint, which is reliable and easy to disassemble and assemble; the protective cover and the extension cover can block the splashing of mud and stones during the tilling process, which protects the internal rotary tilling components and improves the safety of operation; the mounting frame and the vehicle body are connected by a rotating method, which can adaptively adjust the angle according to the undulation of the field ground during tilling operation, ensuring that the rotary tiller and the extension roller are always in contact with the soil, avoiding the problem of uneven depth, improving the uniformity of tilling, and adapting to uneven farmland terrain.

[0041] Working principle:

[0042] During use, herbicides, pesticides, or liquid fertilizers are added to the mixing tank 10 before operation. The servo motor 22 is then started, and its output power drives the rotating shaft 15 to rotate continuously. The rotating shaft 15 drives the rotating disk 12 to revolve synchronously. Simultaneously, the gear 13 on the rotating disk 12 rotates around the center of the rotating shaft 15, and continuously meshes with the toothed grooves 14 on the inner wall of the mixing tank 10, generating its own rotation. This, in turn, drives the mixing roller 16, which is fixedly connected to the gear 13, to simultaneously revolve and rotate, thus processing various materials inside the mixing tank 10. Multi-directional, thorough mixing ensures uniform concentration of the agent or fertilizer. Simultaneously, the rotating shaft 15 drives the bottom turntable 17 to rotate. The slider 20 at the bottom of the turntable 17 moves in a circular motion with the turntable 17 and slides back and forth within the groove 19 on the swing rod 18. Through the sliding engagement of the slider 20 and the groove 19, the circular motion of the turntable 17 is converted into the reciprocating oscillation of the swing rod 18 around its hinge point with the bottom plate 9. The pressure pump 23 pressurizes the inside of the mixing tank 10, allowing the uniformly mixed material to be delivered to the nozzle 2 via a hose. 1. The nozzle 21 swings back and forth within a set angle with the swing arm 18, achieving a large-area, uniform coverage spraying of the soil to be tilled; the transmission unit 8 transmits power to the rotary tiller 5 through the transmission shaft, and the rotary tiller 5 rotates and drives the extension roller 6 to rotate synchronously through the clamping joint, realizing the rotary tillage and soil turning operation; the mounting frame 2 is rotatably connected to the vehicle body 1 through the connecting rod, and can adaptively adjust the working angle according to the terrain undulations; when it is necessary to adjust the tillage working width, the hydraulic rod 7 is controlled to extend and retract, and the output piston of the hydraulic rod 7 drives the extension roller 6 to rotate synchronously, realizing the rotary tillage and soil turning operation; The spreader 4 rotates relative to the protective cover 3, synchronously driving the extension roller 6 to change the working range, thereby flexibly adjusting the overall soil turning width to adapt to different planting row spacing and plot size; as the vehicle body 1 moves forward, the nozzle 21 first sprays the mixed agent / fertilizer onto the soil surface, and then the rotary tiller 5 and extension roller 6 immediately turn over the sprayed area, directly turning the agent or fertilizer into the soil layer, realizing the rapid mixing of materials and soil, avoiding material volatilization and loss, and completing the continuous integrated operation of "spraying - turning over - mixing".
