Description

Technical Field

[0001] This invention relates to the field of agricultural intelligent equipment technology, and more specifically, to a self-propelled vineyard ditching and fertilizing machine. Background Technology

[0002] Fertilization is a crucial aspect of grapevine growth, and the quality of fertilization directly affects the vine's absorption of nutrients. Rational fertilization is an important measure to ensure stable and increased grape yields.

[0003] Currently, fertilization in China is mostly done manually or using a three-point suspended tractor, with some self-propelled machinery also used. However, these methods present several problems: manual fertilization is inefficient, labor-intensive, and prone to uneven fertilizer distribution due to improper operation, affecting the uniformity of grape growth; three-point suspended fertilizer applicators are severely limited by terrain, making turning difficult in hilly or narrow vineyards, potentially damaging vine supports, and the fertilization depth is difficult to control precisely, possibly resulting in waste of surface fertilizer or insufficient root absorption; while self-propelled machinery is efficient, it suffers from low levels of automation. Furthermore, these machines generally lack intelligent control systems, making precise variable-rate fertilization difficult and prone to localized over-fertilization or nutrient deficiency.

[0004] In view of the above-mentioned problems, a self-propelled vineyard trenching and fertilizing machine was designed. This machine can fertilize areas with grapevines and not fertilize areas without grapevines, and can monitor the amount of fertilizer applied in real time, reducing fertilizer waste and saving costs. This fertilizing machine features optimized fertilization technology, good maneuverability, and reduced labor intensity for workers. Summary of the Invention

[0033] In some specific embodiments, the fertilization assembly includes: a DC motor 26, a DC motor speed controller 23, a fertilizer discharger 214, a fertilizer discharge pipe 28, a hexagonal rod 29, and a bearing seat 27. The fertilizer discharger 214 is located on the lower side of the bottom plate of the fertilizer box 22. The DC motor 26 is connected to the fertilizer discharger 214 through the hexagonal rod 29 and the bearing seat 27. One end of the fertilizer discharger 214 is connected to the fertilizer discharge pipe 28.

[0034] In some specific embodiments, the fertilization assembly further includes: a furrow opener beam 313, a plow tip 39, a retaining plate 310, a soil dividing plate 38, and a feed pipe 37. The feed pipe 37 is welded to the rear of the furrow opener beam 313, and the other end of the feed pipe 37 is connected to the fertilizer discharge pipe 28. The plow tip 39 is installed at the front end of the furrow opener beam 313. Two soil dividing plates 38 are welded in parallel to the rear side of the retaining plate 310. The furrow opener beam 313 has several equidistant through holes.

[0035] In some specific embodiments, the fertilization assembly further includes: a soil covering disc 36, a soil covering support 35, and a limiting spring 34. The hollow round tubes on the soil covering disc 36 and the soil covering support 35 are connected and symmetrically spaced. The hollow round tubes on the soil covering support 35 and the limiting spring 34 can adjust the soil covering angle and the vertical height of the soil covering disc 36.

[0036] In some specific embodiments, the mounting plate 33 is connected to the slide rail 19 via the first connecting plate 32 and the guide roller 312. The mounting plate 33 has two through holes at the front and rear, and a pair of second connecting plates 311 are provided at the front through hole at a symmetrical interval. The front through hole and the second connecting plates 311 are connected to the trencher beam 313, and the rear through hole is connected to the soil covering support 35. One end of the suspension bracket 314 is connected to one end of the electric push rod 31, the other end of the suspension bracket 314 is connected to the mounting plate 33, and the other end of the electric push rod 31 is connected to the side frame 111. The motor drive module, motor reducer 115, battery pack A112, battery pack B24, wireless receiver, main controller, gasoline engine 211, generator 212, DC motor 26 and DC motor speed controller 23 are connected by wires.

[0037] It should be understood that the entire machine uses the main frame 113 as its core support structure, and the various components achieve closed-loop operation through modular assembly. The operator issues control commands using a remote control handle, and the wireless receiver inside the control box 17 receives the signals in real time. These signals are then processed by the built-in main controller and synchronously transmitted to the motor drive module, DC motor speed controller 23, electric push rod 31, and other electronic control components, enabling remote control of the entire process, including machine movement, operation adjustment, ditching, fertilization, and soil covering. The power supply adopts a dual-source complementary mode of gasoline and electricity. The gasoline engine 211 drives the generator 212 to generate electricity, which, together with the battery pack A112 inside the main frame 113 and the battery pack B24 on the top, continuously supplies power to all electronic control components. The heat dissipation holes on the side wall of the outer casing 213 can dissipate the heat from the power components in real time, preventing high-temperature failures.

[0038] During operation, the motor drive module, in conjunction with the motor reducer 115, drives the drive wheels 11 of the tracked chassis. With the support of the support rollers 12, auxiliary rollers 16, track brackets 15, and track beams 13, the track 14 enables the machine to move smoothly across the vineyard, adapting to complex terrain. During the depth and height adjustment phase, the electric push rod 31 extends and retracts, causing the suspension frame 314 to shift, which in turn pulls the mounting plate 33 to slide up and down along the slide grooves 18 and rails 19 of the side frame 111. The side frame 111 is securely connected to the main frame 113 via U-shaped buckles 110, ensuring stability during adjustment. In the trenching stage, the plowshare tip 39 at the front end of the trencher beam 313 breaks the soil and opens the trench. The retaining plate 310 blocks excess loose soil, and two soil dividing plates 38 divert the soil in parallel to prevent the trench from collapsing. The fertilizer box 22 is covered with a cover plate 21 to prevent impurities from entering, and its inclined bottom plate guides the fertilizer to converge towards the fertilizer discharger 214. The DC motor 26 drives the fertilizer discharger 214 to rotate at a uniform speed through the hexagonal rod 29 and bearing seat 27. The metered fertilizer is accurately dropped into the trench through the fertilizer discharge pipe 28 and the feed pipe 37. The DC motor speed controller 23 can adjust the fertilizer discharge rate in real time. Finally, a pair of covering discs 36 rotate to cover the soil under the support of the covering support 35. The limiting spring 34, in conjunction with the hollow round tube of the covering support 35, flexibly adjusts the covering angle and height, completing the integrated operation of trenching, fertilization, and covering.

[0039] Remote control is safer and more labor-saving. The control box 17 integrates wireless receiving and main control functions, enabling remote wireless control without the need for operators to be close to the field. This avoids the safety risks of machinery collisions and grapevine scratches, and significantly reduces the intensity of manual labor, meeting the needs of large-scale and intensive management of vineyards. Secondly, it has excellent adaptability to terrain and operation. The tracked chassis 14 fits the soft soil in the field, and its passability is much higher than that of wheeled chassis, avoiding crushing the grape roots. The sliding grooves 18 and sliding rails 19 of the side frame 111, together with the electric push rod 31, can precisely adjust the working height of the fertilization components. The equidistant through holes of the furrow opener beam 313 can flexibly adjust the furrowing depth, and the limit spring 34 can finely adjust the soil covering angle of the soil covering disc 36. It is perfectly adapted to vineyards with different ages, different plant spacing, and different soil types, maximizing operational flexibility.

[0040] Integrated operation doubles efficiency. The equipment integrates three core functions: ditching, fertilizer application, and soil covering. The ditching is completed seamlessly by the plowshare tip 39, the fertilizer applicator 214, and the soil covering disc 36, eliminating the cumbersome procedures of traditional manual labor or multiple equipment rotations. A single unit can complete the entire fertilization process, increasing efficiency several times over compared to traditional methods. Simultaneously, it offers high precision and zero waste. The DC motor 26, in conjunction with the DC motor speed controller 23, ensures precise and controllable fertilizer application. The inclined bottom plate of the fertilizer tank 22 ensures smooth fertilizer dispensing without residue, preventing fertilizer accumulation and waste, achieving precise and quantitative fertilization, and improving fertilizer utilization. Furthermore, dual-power operation ensures uninterrupted operation. The gasoline engine 211, generator 212, and battery packs A112 and B24 form a complementary oil-electric power system, completely solving the problems of power outages and insufficient range in the field, ensuring long-term continuous operation. Finally, the structure is stable and easy to maintain. The main frame 113 and the side frame 111 are fastened together by U-shaped buckles 110, making disassembly and assembly simple. The outer cover 213 protects the power components and bearing seats 27, reducing component wear. The modular design of the whole machine reduces the difficulty of maintenance, effectively extends the service life of the equipment, and reduces the cost of vineyard cultivation and maintenance.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
