Description

Technical Field

[0001] This utility model is an agricultural machine, specifically an integrated machine for fertilizing, pipe laying, and covering soil on onions. Background Technology

[0002] Onions are a common vegetable, and their cultivation has evolved from individual household production to large-scale mechanized cooperative production, with corresponding advancements in planting machinery. Currently, most onion planting machines are tractor-driven. The process involves loosening the soil with a rotary tiller, leveling the ground, planting the seedlings, laying drip irrigation pipes and a plastic film, and then securing the film with soil. However, a significant portion of these steps still requires manual labor, necessitating a large workforce and incurring substantial production costs. The final step, covering the soil and pressing the film, requires multiple people to operate behind the tractor, resulting in low efficiency, high labor costs, and uneven yields. Improvements to existing machinery are needed to meet production demands. Summary of the Invention

[0003] In response to this, this utility model proposes an integrated machine for fertilizing, pipe laying, and soil covering onions, which enables the fertilization, pipe laying, and soil covering operations of onion planting to be completed simultaneously by one machine, thereby improving work efficiency, ensuring stable and uniform planting quality, and overcoming the shortcomings of existing technologies.

[0004] This utility model proposes an integrated onion fertilization, pipe laying, and soil covering machine, which includes a tiller, a press roller, a fertilizer tank, a drip irrigation tape support, and a soil covering frame. The key feature is that the rotary tiller and press roller are mounted on the press roller frame, with the rotary tiller positioned in front of the press roller. The press roller frame has a traction component connected to a tractor, and the rotary tiller is connected to the tractor's output shaft for transmission. The drip irrigation tape support is mounted on the press roller frame, and the fertilizer tank's outlet is in front of the rotary tiller to allow fertilizer to be turned and buried in the soil. The soil covering frame is pinned to the tail of the press roller frame. The soil covering frame is equipped with a film roll frame, a film guide roller, a soil gathering wheel, and a soil covering roller. The soil covering roller is a hollow cylinder located behind the film guide roller, with soil inlets at both ends and soil covering holes on the cylinder arms to allow soil entering the cylinder to re-exit and press the film. The soil covering wheel is mounted on both sides of the soil covering roller to gather soil into the soil covering roller.

[0005] The covering frame has push rod connection holes to allow for the installation of hydraulic push rods between the covering frame and the pressure roller frame. The hydraulic pipes of the hydraulic push rods are connected to the hydraulic lines of the dragging phase.

[0006] The covering roller is mounted on the covering frame via its rocker arm, and a covering roller spring is installed between the rocker arm and the covering frame for cushioning.

[0007] The soil-collecting wheel has a disc-shaped structure and an angle between it and the soil inlet of the covering roller to facilitate soil collection.

[0008] The soil-collecting wheel also has a spring buffer between its rocker arm and the soil-covering frame.

[0009] The press roller is mounted on the press roller frame via press roller arms at both ends, and the shaft of the press roller moves within the floating groove of the press roller frame.

[0010] The soil covering frame is equipped with a loosening shovel in front of the soil gathering wheel so that the soil can be raised and gathered into the soil covering roller.

[0011] The fertilizer bin can be separated into a pesticide bin for applying pesticides when needed.

[0012] A floating pressure roller is installed between the soil-collecting roller and the guide roller to ensure that the film is pressed down before covering to prevent it from being blown away by the wind.

[0013] This invention works as follows:

[0014] Place the fertilizer to be applied into the fertilizer box, and attach the drip irrigation tape roll and film roll to their respective supports. The tractor, carrying this invention, drives to the edge of the cultivated land, uses the Beidou or GPS navigation system to plan and locate the plot, and sets the tractor to automatic driving mode to prepare for work.

[0015] First, loop the ends of the drip irrigation tape and film around the guide roller and secure them at the back of the field. Using the hydraulic pump switch, lower the pressing roller and covering roller onto the film. Start the tractor and allow it to drive forward automatically. Simultaneously, open the fertilizer bin, and fertilizer is automatically applied to the front of the rotary tiller, where it is turned over and buried in the soil. The compaction roller then flattens the soil surface, and the drip irrigation tape and film are automatically laid on the soil. The soil-gathering wheel gathers and scrapes loose soil from both sides into the covering roller, flowing out through the covering holes to form a row that presses down on the film. When the tractor reaches the back of the field, the fertilization, pipe laying, film covering, and soil covering operations are complete. At this point, cut the film and drip irrigation pipe, turn the tractor around, and repeat the same operation along the previously laid edge. This process is repeated until the planned plot is completed.

[0016] Specialized mulch film is ordered, with pre-marked planting holes. One to two people work per row of film to insert the onion seedlings into the soil through the holes. This eliminates the need for manual shoveling and covering with mulch after planting, saving time, increasing efficiency, and reducing production costs.

[0017] Therefore, this invention enables one machine to simultaneously complete the fertilization, pipe laying, and soil covering operations of onion planting, thereby improving efficiency, reducing costs, and ensuring stable and uniform planting quality. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, the pressure roller frame 16 is welded from two steel plates and angle steel. The rotary tiller 3 is mounted on the pressure roller frame, and its input shaft is connected to the output shaft of the tractor for transmission. The fertilizer box 1 is mounted above the rotary tiller. The press roller 4 is mounted in the floating groove 1601 on the pressure roller frame via the pressure roller shaft 401, the pressure roller arm 17, and the pressure roller swing shaft 402, allowing it to float up and down according to the softness and unevenness of the tilled soil surface. The drip irrigation tape bracket 11 is welded and fixed to the pressure roller frame, or it can be fixed to the wall of the medicine box. The upper end of the drip irrigation tape bracket generally has a fork or round hole for installing the drip irrigation tape wheel 12. The medicine box 2 can be formed by dividing the fertilizer box with a partition. The discharge ports of the fertilizer box and the medicine box lead to the front of the rotary tiller, and there is a switch tongue on the discharge channel to control the discharge.

[0027] A traction component 15 is welded onto the pressure roller frame to accommodate connection with a tractor.

[0028] The soil covering frame 20 is generally welded from steel materials such as angle steel and square frame steel. It is connected to the soil covering frame pin connection hole 1602 on the pressure roller frame via a pin shaft. The soil covering frame has a push rod connection hole 14 for installing a hydraulic push rod 19 between the soil covering frame and the pressure roller frame, so that the soil covering frame can be raised and lowered. The film roll frame 13 is fixed on the soil covering frame and has a fork at its upper end for placing the film roll spool. A guide roller 5 is installed below the film roll frame. Behind the guide roller are two floating film pressing rollers 6, which press down the two sides of the film. Behind the film pressing rollers are two soil gathering rollers 7, which are installed in a figure-eight shape to gather and scrape the soil on both sides into the soil covering roller 8.

[0029] The covering roller 8 has four covering holes 801 on its cylinder wall to neatly throw the covering soil onto the film, ensuring accurate positioning of the pre-drilled planting holes between adjacent covering layers. Each end of the covering roller has three inlet holes 803 through which the soil-gathering wheel scrapes soil into the covering roller. The covering roller is mounted on the covering frame via its shaft and covering roller rocker arm 802, and a covering roller spring 10 is installed between the covering roller rocker arm and the covering frame to cushion impacts from hard objects such as stones. Correspondingly, the soil-gathering wheel is also equipped with a soil-gathering spring 9 for the same purpose.

[0030] To ensure proper soil collection and scraping by the soil-collecting wheel, a loosening shovel 18 is installed in front of it. This shovel is mounted on both sides of the covering frame, behind the compaction roller, to loosen and raise the soil, allowing the soil-collecting wheel to smoothly scrape it into the covering roller. The soil-collecting wheel is disc-shaped to facilitate soil collection and scraping.

[0031] This utility model is adapted to large and medium-sized tractors. Components and reference numerals not mentioned are as described above.

[0032] The working principle of this utility model is further described as follows: A tractor is connected for traction via a traction component 15; an electric motor drives a fertilizer applicator to spread base fertilizer; the tractor's drive shaft drives a rotary tiller to loosen the soil and bury the fertilizer; an electric motor drives an electric pump for pesticide application (when needed); a hydraulic motor drives a hydraulic push rod 11 to control the raising and lowering of the covering frame; the compaction roller is designed to be floating to better maintain consistent soil compaction; subsequently, drip irrigation tape and mulch film are laid; finally, a covering roller is used to cover the film with soil. These designs enable the onion fertilization, pipe-laying, and mulching integrated machine to play a stable role in improving production efficiency, reducing labor intensity, and promoting sustainable agricultural development.
