Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and particularly relates to a quantitative anti-blocking soil-breaking and fertilizing integrated device. Background Art

[0002] Traditional soil loosening and fertilizing devices often face problems such as insufficient fertilization accuracy, easy blockage, and soil backfilling in agricultural operations, especially under the conditions of heavy clay soil; in the prior art, the functions of soil loosening and fertilizing mostly adopt a split design, resulting in a complex structure, low operation efficiency, and difficult accurate control of the fertilization amount. For example, conventional devices are prone to blockage of the fertilization port due to soil adhesion during the soil loosening process, resulting in uneven or interrupted fertilizer distribution; at the same time, when the soil loosening rod returns, the soil is prone to backflow and backfilling, affecting the retention effect of fertilizers in the roots and causing a decrease in utilization rate; in addition, most devices lack a quantitative fertilization mechanism and rely on manual adjustment or mechanical valve control, with defects such as large fluctuations in fertilization amount and poor adaptability, and it is difficult to meet the requirements of precision agriculture. Summary of the Invention

[0003] The present invention aims to provide a quantitative anti-blocking soil-breaking and fertilizing integrated device to solve the technical problems of insufficient fertilization accuracy, easy blockage, and soil backfilling of existing soil loosening and fertilizing devices.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A quantitative anti-blocking soil-breaking and fertilizing integrated device includes a fertilizer storage tank. A bracket is installed at the bottom of the fertilizer storage tank, and a fertilizing and soil loosening rod and an automatic reciprocating soil-breaking mechanism are arranged on the bracket. Under the action of the automatic reciprocating soil-breaking mechanism, the fertilizing and soil loosening rod can move up and down on the bracket;

[0006] The fertilizing and soil loosening rod is a hollow tubular structure, and the lower end of the fertilizing and soil loosening rod is a pointed structure. A central rod is arranged inside the fertilizing and soil loosening rod, and a conical head structure is arranged at the lower end of the central rod. The fertilizer storage tank is connected to the fertilizing and soil loosening rod through a fertilizer pipe. A plurality of fertilizer outlets are opened at the lower part of the fertilizing and soil loosening rod. All the fertilizer outlets are arranged along the circumferential direction, and the fertilizer outlets correspond to the conical head structure. A anti-blocking valve plate structure is arranged at each fertilizer outlet;

[0007] A gravity-type quantitative fertilizer dropping component is arranged inside the fertilizing and soil loosening rod. The gravity-type quantitative fertilizer dropping component includes three fan plates. The three fan plates are arranged around the central rod. One side edge of each fan plate is hinged to the inner wall of the fertilizing and soil loosening rod and the central rod through a pin shaft. A spring is connected to each fan plate, and the end of the spring is connected to the central rod.

[0008] Further, the automatic reciprocating soil-breaking mechanism includes a driving motor and a crank-link mechanism. The driving motor is connected to the fertilizing and soil loosening rod through the crank-link mechanism; A return spring and a circular plate are sleeved on the upper part of the fertilizing and soil loosening rod. The two ends of the return spring are connected to the circular plate and the bracket.

[0009] Furthermore, the anti-blocking valve plate structure includes a baffle, a movable plate and a pin. The pin is arranged on the outer wall of the fertilizing and soil-loosening rod. A long hole is provided on the movable plate. The movable plate is closely attached to the outer wall of the fertilizing and soil-loosening rod, and the pin is located in the long hole. The movable plate can slide up and down along the pin. The baffle is arranged at the upper end of the movable plate. When the movable plate moves downward, the movable plate can block the corresponding fertilizer outlet.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: By the coordinated operation of the driving motor, the crank and connecting rod mechanism, the gravity-type quantitative fertilizer dropping component and the anti-blocking valve plate structure, the present invention solves the problem of the coordinated operation of soil loosening and fertilization, and significantly improves the fertilization accuracy and anti-blocking ability under the condition of heavy clay soil. Its quantitative control mechanism reduces fertilizer waste, and the anti-blocking valve plate with a conical head structure fundamentally inhibits the problem of soil backfill, which is especially suitable for the efficient and precise fertilization of deep-rooted crops such as corn and sugarcane.

[0019] The present invention will be further described in detail below in conjunction with embodiments.

[0020] As Figures 1-6 shown, Specific Embodiment 1 of a quantitative anti-blocking soil-breaking and fertilizing integrated device provided by the present invention:

[0021] A quantitative anti-blocking soil-breaking and fertilizing integrated device includes a fertilizer storage tank 1. A bracket 2 is installed at the bottom of the fertilizer storage tank 1. A fertilizing and soil-loosening rod 4 and an automatic reciprocating soil-breaking mechanism are arranged on the bracket 2. Under the action of the automatic reciprocating soil-breaking mechanism, the fertilizing and soil-loosening rod 4 can move up and down on the bracket 2; the automatic reciprocating soil-breaking mechanism includes a driving motor 12 and a crank-link mechanism 8. The driving motor 12 is connected to the fertilizing and soil-loosening rod 4 through the crank-link mechanism 8; A return spring 5 and a circular plate 6 are sleeved on the upper part of the fertilizing and soil-loosening rod 4. Both ends of the return spring 5 are connected between the circular plate 6 and the bracket 2.

[0022] The fertilizing and soil-loosening rod 4 is of a hollow tubular structure. The lower end of the fertilizing and soil-loosening rod 4 is of a pointed structure. A central rod 15 is arranged inside the fertilizing and soil-loosening rod 4. A conical head structure 9 is arranged at the lower end of the central rod 15. The fertilizer storage tank 1 is connected to the fertilizing and soil-loosening rod 4 through a fertilizer pipe 3. A plurality of fertilizer outlets 10 are opened at the lower part of the fertilizing and soil-loosening rod 4. All the fertilizer outlets 10 are arranged along the circumferential direction, and the fertilizer outlets 10 correspond to the conical head structure 9. A anti-blocking valve plate structure is arranged at each fertilizer outlet 10; The anti-blocking valve plate structure includes a baffle 7, a movable plate 11 and a pin 16. The pin 16 is arranged on the outer wall of the fertilizing and soil-loosening rod 4. A long hole 17 is opened on the movable plate 11. The movable plate 11 is closely attached to the outer wall of the fertilizing and soil-loosening rod 4, and the pin 16 is located in the long hole 17. The movable plate 11 can slide up and down on the pin 16. The baffle 7 is arranged at the upper end of the movable plate 11; When the movable plate 11 moves downward, the movable plate 11 can block the corresponding fertilizer outlet 10.

[0023] A gravity-type quantitative fertilizer dropping component is arranged inside the fertilizing and soil-loosening rod 4. The gravity-type quantitative fertilizer dropping component includes three fan plates 13. The three fan plates 13 are arranged around the central rod 15. One side of each fan plate 13 is hinged to the inner wall of the fertilizing and soil-loosening rod 4 and the central rod 15 through a pin shaft. A spring 14 is connected to each fan plate 13. The end of the spring 14 is connected to the central rod 15.

[0024] The quantitative anti-blocking soil-breaking and fertilizing integrated device of this embodiment mainly realizes synchronous operation of soil loosening and fertilizing, accurately controls the fertilization amount, and prevents soil backfill through the coordinated design of the driving motor 12, the crank-link mechanism 8, the gravity-type quantitative fertilizer dropping component and the anti-blocking valve plate structure. The specific working principle is as follows:

[0025] The drive motor 12 drives the fertilizer application and soil loosening rod 4 to move vertically in a reciprocating manner through the crank - connecting rod mechanism 8. The fertilizer in the fertilizer storage tank 1 falls into the fertilizer application and soil loosening rod 4 through the fertilizer pipe 3. The gravity - type quantitative fertilizer - dropping assembly controls the opening of the fan - shaped plate 13 according to the amount of fertilizer. When the fertilizer falling on the fan - shaped plate 13 reaches a certain amount, the gravity of the fertilizer presses the fan - shaped plate 13, causing the fan - shaped plate 13 to rotate around the pin shaft, and the fertilizer slides off the fan - shaped plate 13. The spring 14 is used for the reset of the fan - shaped plate 13. All the fertilizer of a certain weight slides down to the cone - head structure 9. During operation, in the stage of the fertilizer application and soil loosening rod 4 being inserted downward, when the lower part of the fertilizer application and soil loosening rod 4 enters the soil, due to being blocked by the soil, the baffle 7 and the movable plate 11 move upward relative to the fertilizer application and soil loosening rod 4, thus opening the fertilizer outlet 10. The fertilizer on the cone - head structure 9 (made of a metal material with a small coefficient of friction) slides down to the soil through the fertilizer outlet 10. When returning, the fertilizer application and soil loosening rod 4 emerges from the soil. Due to the loss of the soil acting force, the baffle 7 slides downward, thereby closing the fertilizer outlet 10 to prevent soil from entering the interior of the fertilizer application and soil loosening rod 4.
