Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery engineering technology, and in particular to an integrated ridging and fertilizing machine. Background Technology

[0002] A rotary tiller is a power-driven soil tillage machine with strong soil breaking ability. It can achieve the effect of plowing and harrowing several times in one operation. After tilling, the surface is flat and soft, which can save time and labor.

[0003] Existing patent CN204634281U discloses a concave tobacco field ridging machine. It includes a frame, blades, and a shaping device, wherein the shaping device is fixed to the frame and located behind the blades, and the shaping device includes at least one set of shaping units. This ridging device has a relatively simple function, lacking a fertilization mechanism, and cannot perform fertilization operations simultaneously with rotary tillage and ridging. Therefore, a separate fertilization operation is required before rotary tillage, and the amount of fertilizer cannot be precisely controlled, easily resulting in over- or under-fertilization, increasing the number of operations and labor costs, and failing to meet the agronomical requirements of integrated ridging and fertilization operations in modern tobacco cultivation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an integrated machine for ridging and fertilizing.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a ridge-fertilizing integrated machine, including a rotary tiller and a ridge cover set at the rear end of the rotary tiller. The upper end of the rotary tiller is provided with a fertilizer box for holding fertilizer. The fertilizer box is provided with a feeding mechanism. The front end of the fertilizer box is provided with a discharge pipe communicating with its interior. The discharge pipe is located in front of the rotary tiller. The feeding mechanism is used to transport the fertilizer in the fertilizer box to the discharge pipe.

[0006] Furthermore, there are two fertilizer bins symmetrically arranged on the upper part of the rotary tiller.

[0007] Furthermore, the feeding mechanism includes a semi-circular conveying groove at the bottom of the fertilizer box, a conveying shaft inside the semi-circular conveying groove, and spiral blades outside the conveying shaft. A drive motor is provided at the rear end of the fertilizer box. The output shaft of the drive motor extends into the semi-circular conveying groove and its end is connected to the conveying shaft. The semi-circular conveying groove is connected to the discharge pipe.

[0008] Furthermore, the output shaft of the drive motor is connected to the conveyor shaft via a coupling.

[0009] Furthermore, the fertilizer box is shaped like an inverted square pyramid with an opening at the top.

[0010] Furthermore, the fertilizer box has two connecting plates at its lower end, which are connected to the upper end of the rotary tiller by welding.

[0011] Furthermore, there are two ridging covers, which are symmetrically arranged at the rear end of the rotary tiller. Each ridging cover includes a ridging top plate and ridging side plates located on both sides of the ridging top plate. The ridging top plate and the two ridging side plates form a trapezoidal cavity with a gradually narrowing cross section.

[0012] Furthermore, a ridging pressure plate is provided between the ridging top plate and the ridging side plate, and the ridging pressure plate is located at the rear end of the ridging cover.

[0013] The beneficial effects of this application are as follows: 1. By integrating a fertilizer box and feeding mechanism onto a rotary tiller and setting a discharge pipe at the front of the rotary tiller, this application achieves precise and uniform application of fertilizer before rotary tillage and ridging. Subsequently, the rotary tillage blades can fully mix the fertilizer with the soil, effectively solving the problem of existing equipment having a single function and requiring step-by-step operation, and greatly improving work efficiency.

[0014] 2. The system uses two symmetrically arranged fertilizer bins, which can be used to fertilize both ridges at the same time, further improving work efficiency and the uniformity of fertilization. It is especially suitable for large-scale field operations.

[0015] 3. The feeding mechanism adopts a design where a drive motor rotates the spiral blades. This design is simple and compact, ensuring stable and reliable material conveying. It effectively prevents fertilizer from becoming lodged or blocked within the box, achieving continuous and uniform delivery and guaranteeing fertilization quality. The fertilizer box is designed in the shape of an inverted quadrangular pyramid. Its sloping structure facilitates the automatic convergence of fertilizer to the semi-circular conveying groove at the bottom under gravity.

[0016] 4. The ridging cover adopts a special trapezoidal cavity structure. Its gradually narrowing cross-section design allows the soil to be smoothly guided, compressed, and shaped into high-quality ridges that meet agronomic requirements, resulting in excellent shaping. A ridging pressure plate is added at the rear end of the ridging cover to further compact and shape the surface of the formed ridges, making the ridge structure more compact and effectively preventing soil collapse.

[0022] Please see Figure 1-3 This utility model embodiment provides a ridge-fertilizing integrated machine, including a rotary tiller 1 and a ridge cover 2 set at the rear end of the rotary tiller 1. The upper end of the rotary tiller 1 is provided with a fertilizer box 4 for holding fertilizer. The fertilizer box 4 is provided with a feeding mechanism 5. The front end of the fertilizer box 4 is provided with a discharge pipe 41 that communicates with the inside of the fertilizer box 4. The discharge position of the discharge pipe 41 is located in front of the rotary tiller 1. The feeding mechanism 5 is used to transport the fertilizer in the fertilizer box 4 to the discharge pipe 41.

[0023] The rotary tiller 1 is connected to a tractor, which pulls the rotary tiller 1 forward. The rotary tiller 1 includes a frame and rotary blades, and the fertilizer box 4 and ridging cover 2 are both mounted on the frame. The rotary tiller 1 uses existing rotary tillage equipment, and its specific structure will not be described in detail here.

[0024] Specifically, there are two fertilizer bins 4 arranged symmetrically. The feeding mechanism 5 includes a semi-circular conveying groove 54 located at the bottom of the fertilizer bin 4, a conveying shaft 52 located within the semi-circular conveying groove 54, and spiral blades 53 located outside the conveying shaft 52. A drive motor 51 is located at the rear end of the fertilizer bin 4. The output shaft of the drive motor 51 extends into the semi-circular conveying groove 54 and its end is connected to the conveying shaft 52. The semi-circular conveying groove 54 is connected to the discharge pipe 41. The output shaft of the drive motor 51 is connected to the conveying shaft 52 via a coupling. A support plate 55 is provided on the outer wall of the fertilizer bin 4, and the drive motor 51 is mounted on the support plate 55. When the drive motor 51 is working, it drives the conveying shaft 52 and the spiral blades 53 on it to rotate, pushing the fertilizer towards the discharge pipe 41. Below the opening of the discharge pipe 41 is the uncultivated land in front of the rotary tiller 1. This application also includes a PLC controller, and the drive motor 51 is a speed-regulating motor. The PLC controller is electrically connected to the drive motor 51 and is used to adjust the speed and start / stop of the drive motor 51, thereby achieving precise control of the fertilizer application amount.

[0025] The fertilizer bin 4 is shaped like an inverted frustum pyramid with an open top. Its sloping structure allows fertilizer to automatically collect at the bottom semi-circular conveying groove 54 under gravity, facilitating its smooth descent. Two connecting plates 42 are positioned opposite each other at the lower end of the fertilizer bin 4, and are welded to it. The connecting plates 42 are also welded to the upper end of the rotary tiller 1. It should be noted that any parts not detailed in this application are prior art.

[0026] Furthermore, there are two ridging covers 2, symmetrically arranged at the rear end of the rotary tiller 1. Each ridging cover 2 includes a ridging top plate 21 and two ridging side plates 22 located on either side of the top plate 21. The top plate 21 and the two side plates 22 form a trapezoidal cavity with a gradually narrowing cross-section. The top plate 21 and the side plates 22 form a trapezoidal tunnel-like cavity with a large opening at the front end and a small opening at the rear end. A ridging pressure plate 23 is provided between the top plate 21 and the side plates 22. The ridging pressure plate 23 is located at the rear end of the ridging cover 2 and is used to compact the soil passing through it. The ridging pressure plate 23 is triangular and has three connecting ends, which are respectively connected to the rear edge of the top plate 21, the rear edge of the side plates 22, and the connection point between the top plate 21 and the side plates 22.

[0027] During operation, the tractor pulls the entire machine forward. The drive motor 51 is started, causing the auger blades 53 to rotate, steadily conveying fertilizer from the fertilizer bin 4 to the discharge pipe 41 and spreading it on the ground in front of the rotary tiller 1. Immediately afterwards, the rotary tiller 1's blades rotate, tilling the soil where fertilizer has just been spread. During this process, the soil is thoroughly broken up and mixed with the fertilizer. Finally, the tilled and fertilizer-mixed soil is thrown into the ridging hood 2 at the rear. Under the constraint and compression of the gradually narrowing cavity of the ridging hood 2, a preliminary ridge shape is formed, and the final compaction and shaping are performed by the ridging plate 23 at the end, thus completing the entire process of fertilization, soil mixing, and ridging in one operation.

[0028] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
