Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to an integrated machine for deep plowing and mulching tobacco fields. Background Technology

[0002] In tobacco cultivation, deep tillage can loosen the soil and improve soil moisture, but the pollution problem caused by residual agricultural film (referred to as "film residue") is becoming increasingly serious. Traditionally, during the tobacco field cleanup stage, a field film removal machine is required, and deep tillage and film removal are carried out separately. This requires the separate use of a deep tillage plow and a film residue recycling machine, which is inefficient, costly, and the film residue easily gets tangled in agricultural machinery parts.

[0003] Furthermore, the efficiency of existing residual film recycling machines is as follows: 1.25 m operating width, 5-6 mu / hour operating efficiency, 95-98% film recycling rate, 20-30 cm deep tillage, 92%-95% film recycling rate, low recycling efficiency.

[0004] Meanwhile, existing residual film recycling machines experience film splattering during the cleaning process and collect a large amount of soil clumps, causing the machine to need to unload waste after operating for only a short distance, increasing the workload of manual stripping of soil and film waste. Summary of the Invention

[0005] To achieve integrated deep tillage and film removal operations, and to simultaneously complete deep tillage, soil breaking, film removal, film-soil separation, and film collection in a single pass, thereby reducing labor intensity, improving operational efficiency, and reducing costs, this utility model provides an integrated deep tillage and film removal machine for tobacco fields. Its features are: it consists of a power traction frame, a deep tillage module, a film removal module, a film collection module, and an intelligent control system.

[0006] The power traction frame is connected to the tractor's power take-off shaft, providing the machine with propulsion and hydraulic power.

[0007] The deep tillage module is horizontally connected to the rear of the power traction frame and is equipped with a curved deep loosening shovel for breaking up the compacted layer. A rotary tillage and soil-breaking roller is installed on the rear side of the curved deep loosening shovel for breaking up soil clods and reducing the particle size of the soil clods to ≤5cm, thereby separating the soil clods from the residual film.

[0008] The film-cleaning module is inclinedly connected to the rear of the deep tillage module. It includes an internal toothed picking roller and a soil-screening cylinder fitted outside the toothed picking roller. The bottom of the soil-screening cylinder is equipped with a double-layer reciprocating vibrating screen. A guide channel is provided on the lower front side of the soil-screening cylinder. The guide channel is inclined downward and opens towards the rotary tillage crushing roller. The soil clods crushed by the rotary tillage crushing roller and the separated residual film flow into the soil-screening cylinder along the guide channel. The double-layer reciprocating vibrating screen screens out the soil clods and they fall back to the ground. The toothed picking roller rotates and picks out the residual film from the soil clods. A fan is provided on the longitudinal inner wall of the front side of the soil-screening cylinder. The air outlet of the fan faces rearward and blows out the residual film on the toothed picking roller while preventing soil clods from mixing into the residual film.

[0009] The residual film collection module is connected to the rear of the film cleaning module and includes a screw conveyor and a compression film collection box. The screw conveyor is inclined and its conveying surface faces the direction of the airflow from the blower. After the blower blows the residual film off the toothed picking roller, the residual film falls onto the screw conveyor and is conveyed by the screw conveyor to the compression film collection box at the rear.

[0010] The top of the curved deep tillage shovel is provided with mounting holes spaced from top to bottom. By using different mounting holes, the height of the curved deep tillage shovel can be adjusted, thereby adjusting the depth of deep tillage. The adjustment range is 30cm-50cm.

[0011] The number of curved deep loosening shovels is greater than 3, arranged in a row and evenly distributed in the horizontal direction.

[0012] The double-layer reciprocating vibrating screen includes an upper screen and a lower screen. The upper screen has a screen hole diameter of 20 mm and is used to separate large soil particles. The lower screen has a screen hole diameter of 5 mm and is used for secondary filtration of fine soil.

[0013] The spring teeth on the spring tooth pickup roller are made of spring steel and coated with an anti-stick coating. When residual film gets entangled, the spring teeth can elastically reset, thereby preventing residual film from getting entangled on the spring tooth pickup roller.

[0014] The power traction frame is also equipped with an intelligent control system, which is electrically connected to a soil hardness sensor and a camera. At the same time, the intelligent control system is also electrically connected to the power system.

[0015] The power system includes an electric push rod mounted on the top of the curved deep loosening shovel and a rotary motor mounted on the top of the soil screening cylinder.

[0016] The fixed rod of the electric push rod is fixedly connected to the crossbeam on the power traction frame, the reciprocating push-pull rod of the electric push rod is fixedly connected to the top of the curved deep loosening shovel, and the push-pull motor of the electric push rod is electrically connected to the intelligent control system.

[0017] The output shaft of the rotary motor is connected to the central shaft of the toothed pickup roller via a belt. When the output shaft rotates, it drives the central shaft to rotate, which in turn drives the toothed pickup roller to rotate. The rotary motor is electrically connected to the intelligent control system.

[0018] The soil hardness sensor is fixedly installed on the front side of the tire of the power traction frame to detect the hardness of the field and transmit the hardness data to the intelligent control system. After receiving the hardness data of the field, the intelligent control system determines the depth to which the curved surface deep loosening shovel needs to be deep-plowing based on the hardness data, and then controls the operation of the push-pull motor to move the reciprocating push-pull rod up and down, thereby driving the curved surface deep loosening shovel to move up and down and automatically adjusting the deep-plowing depth.

[0019] The camera is used to capture images of the toothed pickup roller and transmit the images to the intelligent control system. After the intelligent control system identifies the residual film density on the toothed pickup roller, it adjusts the rotation speed of the rotary motor according to the residual film density, thereby dynamically adjusting the rotation speed of the toothed pickup roller.

[0020] A rotary cutter is fixedly installed around the central shaft to cut the film strips wound on the central shaft and prevent the central shaft from getting stuck.

[0021] The residual film collection module includes a drive roller on its spiral conveyor. A rotary cutter is also fixedly installed around the drive roller to cut the film strips wound on the drive roller and prevent the drive roller from getting stuck.

[0022] This utility model integrates deep tillage and residual film removal functions through modular design, simultaneously completing deep tillage, soil breaking, residual film pickup, film-soil separation, and residual film collection in a single operation, significantly improving work efficiency and promoting labor reduction and cost reduction. It has the following advantages: (1) Collaborative operation capability: While the deep tillage module loosens the soil, it turns the shallow residual film to the surface; the film cleaning module picks up the residual film in time to avoid secondary burial.

[0023] (2) Anti-winding design: The spring teeth are made of spring steel and coated with an anti-stick coating, which can be elastically reset when they are wrapped; a rotary cutter is installed in the key transmission parts to actively cut the wrapping film strip.

[0024] (3) High-efficiency separation of membrane and soil: Vibration screening + airflow cleaning combination technology, residual membrane soil content ≤8%.

[0025] (4) Adaptive adjustment: Automatically optimizes operating parameters based on soil moisture and residual film distribution to adapt to different tobacco field conditions.

[0026] The innovative aspects of this invention are as follows: (1) Functional integration and innovation: It is the first to integrate deep plowing, film cleaning and baling processes, reducing the number of times the soil needs to be entered and reducing soil compaction; (2) Innovation of anti-membrane flying entanglement structure: dynamic obstacle avoidance with elastic teeth + active cutting dual mechanism to solve industry pain points; (3) Innovation of intelligent control system: Real-time optimization of operation parameters based on multi-sensor data to improve adaptability; (4) Environmental benefits innovation: efficient recycling of residual film reduces microplastic pollution and meets the needs of green agriculture.

[0027] In addition to tobacco fields, this machine is also suitable for areas where crops such as tobacco, cotton, and corn are grown under plastic film. It is especially suitable for spring preparation operations in large-scale tobacco fields, which can significantly reduce labor costs and improve the sustainable use of arable land.
