Description

Technical Field

[0001] This invention relates to the technical field of agricultural implements, and more specifically, to an air-delivered, air-fertilizer separation, deep fertilization trenching device. Background Technology

[0002] Chemical fertilizers ensure the nutritional needs of crops during their growth. Side-deep fertilization technology is a scientifically proven and effective topdressing solution, significantly improving root absorption efficiency, reducing fertilizer loss, increasing fertilizer utilization, and mitigating resource and environmental pollution caused by fertilizer runoff. Side-deep fertilization involves equipping rice transplanters with deep fertilizer applicators to apply fertilizer to the soil beside the rice seedlings during transplanting. This technology is also known as side-strip fertilization or machine-transplanted deep fertilization.

[0003] Existing fertilization devices mainly include pneumatic fertilization devices and screw conveyor fertilization devices. Pneumatic fertilization devices rely on high-speed airflow to quickly and forcibly deliver fertilizer to the soil that needs fertilization. However, during rice growth, due to factors such as high soil moisture content, a shallow surface water layer, high soil fluidity, and deep and narrow fertilization trenches, the mud-water mixture is particularly prone to clogging the fertilizer inlet. Furthermore, when using pneumatic fertilization, the lack of an escape route for the airflow makes it easy for the high-speed airflow in the fertilization trench to blow out fertilizer and mud simultaneously, which is detrimental to fertilization operations and seriously affects the implementation and application of rice fertilization. Summary of the Invention

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide an air-fed fertilizer separation deep fertilization trenching device to prevent airflow blockage and the simultaneous blowing out of fertilizer and mud, thereby achieving the effect of air-fed fertilizer separation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A pneumatic-driven, air-fertilizer separation, deep fertilization trenching device includes a trenching mechanism, a contouring mechanism, a connecting mechanism, and a fertilizer discharge mechanism. The trenching mechanism, contouring mechanism, and connecting mechanism are connected sequentially from bottom to top. The connecting mechanism is used to connect with external agricultural machinery. The fertilizer discharge mechanism is connected to the trenching mechanism, and the tail of the contouring mechanism has a slot for installing the fertilizer discharge mechanism.

[0007] The fertilizer discharge mechanism includes a fertilizer inlet and a fertilizer discharge channel connected in sequence. The fertilizer inlet is used to connect to the fertilizer discharge port of an external agricultural machine. The fertilizer discharge channel has a gas venting channel for communicating with the outside air, and the fertilizer discharge channel extends to the bottom of the ditching mechanism. The external fertilizer mixture is transported to the fertilizer discharge channel through the fertilizer inlet. The gas in the fertilizer mixture is discharged through the gas venting channel, and the fertilizer in the fertilizer mixture is discharged into the bottom of the ditch through the fertilizer discharge channel.

[0008] According to a pneumatic-driven deep fertilization trenching device for separating gas and fertilizer according to the present invention, the fertilizer discharge mechanism further includes a material discharge plate extending from below the gas and fertilizer inlet to the bottom of the trenching mechanism and baffles disposed on both sides of the material discharge plate, wherein the material discharge plate and the baffles on both sides form the fertilizer discharge channel, and the space above the baffles on both sides is open to form the gas dissipation channel.

[0009] Furthermore, the blanking plate and the baffle are integrally molded.

[0010] According to a pneumatic conveying and fertilizer separation deep fertilization trenching device of the present invention, the length of the top of the baffle is greater than the length of the bottom of the baffle, and the material dropping plate is gradually inclined towards the tail of the baffle from top to bottom, so that the space enclosed by the baffle and the material dropping plate gradually shrinks from top to bottom.

[0011] Furthermore, the angle between the material drop plate and the baffle is 100°-160°. The tilt angle of the material drop plate lengthens the material drop path, allowing for more even distribution of the fertilizer. Simultaneously, it buffers the high-speed airflow, providing sufficient time for dissipation. Specifically, the space near the material drop plate forms a primary pressure relief channel A for airflow diffusion, while the space above the baffles on both sides connects with the external airflow, forming a secondary pressure relief channel B. Through the primary pressure relief channel A and the secondary pressure relief channel B, the high-speed gas is further ensured to dissipate fully.

[0012] According to a pneumatic conveying type deep fertilization trenching device for separating gas and fertilizer, the bottom of the gas-fertilizer inlet is connected to a material drop plate, and a splash guard is provided on the top of the bottom of the gas-fertilizer inlet to prevent fertilizer from splashing out when the gas-fertilizer mixture falls from the gas-fertilizer inlet to the material drop plate.

[0013] Furthermore, the splash guard is disposed on the upper edge of the two side baffles and partially covers the space above the baffles.

[0014] According to a pneumatic-driven deep fertilization trenching device for separating gas and fertilizer according to the present invention, a soil covering mechanism is further included.

The tail end of the fertilizer discharge mechanism is provided with a receiving plate for receiving and fixing the soil covering mechanism.

[0015] Furthermore, the receiving plate is disposed on the upper edge of the rear of the two side baffles, and the height of the rear of the baffles is lower than the height of the front middle part of the baffles. The receiving plate and the baffles are integrally formed.

[0016] According to a pneumatic-driven deep fertilization trenching device for separating air and fertilizer according to the present invention, the soil covering mechanism includes a flat plate with a notch in the middle of the tail end for draining mud and water; and an inclined plate on each side of the tail end of the flat plate, the inclined plate extending downward and outward, and the inclined plate and the tail end of the flat plate forming an inverted V-shaped structure for soil covering.

[0017] The head of the plate is provided with a hanging ear and / or a mounting hole. The hanging ear is located on both sides of the head of the plate and is used to connect with the contouring mechanism. The mounting hole is located in the middle of the head of the plate and is used to connect with the fertilizer discharge mechanism.

[0018] The angle between the inclined plate and the flat plate is 90° to 145°. The flat plate, the inclined plate, and the hanging lug are integrally molded.

[0019] According to a pneumatic-driven deep fertilization trenching device for separating air and fertilizer according to the present invention, the trenching mechanism is disposed below the contouring mechanism, and the trenching mechanism includes a front-to-back tip trenching part and a trench body holding part. The horizontal cross-section of the tip trenching part is V-shaped, the horizontal cross-section of the trench body holding part is rectangular, and the trench body holding part is connected to the fertilizer discharge mechanism.

[0020] Furthermore, the grooved tip is gradually inclined backward from top to bottom. The V-shaped angle formed by the horizontal cross-section of the grooved tip is 20°-30°.

[0021] The trenching mechanism of this technical solution can perform deep fertilization under high viscosity and high humidity conditions, thereby applying fertilizer deep into the vicinity of the rice roots and providing nutrition for the growth of rice.

[0022] The pointed groove and the groove holding part are integrally formed, and the pointed groove and the groove holding part surround and form a hollow sealed cavity. The groove holding part and the baffle are integrally formed.

[0023] According to a pneumatic-driven deep fertilization trenching device for separating gas and fertilizer according to the present invention, the contouring mechanism is designed in the shape of a ship and includes a contouring bottom plate, wave-proof side plates and a stubble pressing plate. The bottom of the contouring bottom plate is connected to the top of the trenching mechanism, and the wave-proof side plates and the stubble pressing plate are respectively disposed on the two sides and the head of the contouring bottom plate.

[0024] The connecting mechanism is located within the space enclosed by the contoured base plate, the wave-proof side plate, and the stubble plate. The slot is located at the tail of the contoured base plate, and the fertilizer discharge mechanism protrudes from the contoured base plate.

[0025] According to a pneumatic-driven deep fertilization trenching device for separating air and fertilizer according to the present invention, the bottom of the stubble plate is connected to the contoured bottom plate, the top of the stubble plate has an arc-shaped structure, and the stubble plate is gradually inclined outward from the bottom to the top; the height of the wave-proof side plate gradually decreases from front to back; and the front shape of the wave-proof side plate matches the side shape of the stubble plate.

[0040] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses an air-feeding type air-fertilizer separation deep fertilization trenching device, which integrates deep fertilization, trenching, fertilizer application, pressure release, and soil covering. It includes a trenching mechanism 1, a contouring mechanism 2, a connecting mechanism 3, a fertilizer discharge mechanism 4, and a soil covering mechanism 5. Among them, the trenching mechanism 1, the contouring mechanism 2, and the connecting mechanism 3 are connected sequentially from bottom to top. The fertilizer discharge mechanism 4 is connected to the trenching mechanism 1, and the fertilizer discharge mechanism 4 and the trenching mechanism 1 are integrally formed. The tail of the contouring mechanism 2 has a slot for installing the fertilizer discharge mechanism 4. The soil covering mechanism 5 is set at the tail of the fertilizer discharge mechanism 4, and the soil covering mechanism 5 is connected to the tail of the contouring mechanism 2. The contouring mechanism 2 and the connecting mechanism 3 are integrally formed, and the connecting mechanism 3 is used to connect with external agricultural machinery.

[0043] like Figure 2 and Figure 3 As shown, the connecting mechanism 3 further includes two connecting plates 310 vertically arranged on the contouring mechanism 2 and at least one connecting rod 320 for connecting and fixing the two connecting plates 310. The two connecting plates 310 are provided with mounting holes 6 for connecting with the external working body.

[0044] Furthermore, the contouring mechanism 2 is designed in a boat shape, including a contouring base plate 21, wave-breaking side plates 22, and stubble-pressing plates 23. The contouring mechanism 2 floats with the undulations of the field, thereby achieving contouring. The contouring base plate 21 is a horizontally positioned flat plate, with its bottom connected to the top of the ditching mechanism 1. The wave-breaking side plates 22 and stubble-pressing plates 23 are respectively located on the sides and head of the contouring base plate 21, extending upwards; specifically, the wave-breaking side plates 22 are generally obtuse-angled triangles. The connecting mechanism 3 is located on the contouring base plate 21, specifically within the space enclosed by the contouring base plate 21, wave-breaking side plates 22, and stubble-pressing plates 23. The slot for installing the fertilizer discharging mechanism 4 is located at the tail of the contouring base plate 21, and the fertilizer discharging mechanism 4 protrudes from the contouring base plate 21, that is, it protrudes from the space enclosed by the contouring base plate 21, wave-breaking side plates 22, and stubble-pressing plates 23. The soil covering mechanism 5 is located at the rear of the contoured base plate 21, the wave-breaking side plate 22, and the fertilizer discharge mechanism 4. The contoured base plate 21 and the wave-breaking side plate 22 are respectively provided with mounting holes 6 for fixed connection with the trenching mechanism 1 and the soil covering mechanism 5.

[0045] Furthermore, the bottom of the stubble plate 23 is connected to the contour base plate 21, the top of the stubble plate 23 has an arc-shaped structure, and the stubble plate 23 is gradually inclined outward from the bottom to the top; the height of the wave-resistant side plate 22 gradually decreases from front to back; and the front shape of the wave-resistant side plate 22 matches the side shape of the stubble plate 23. The above design of the contour mechanism 2 can separate the seedlings from the middle and upper part of the seedlings to both sides of the ditching mechanism 1 during ditching, avoiding accidental damage to the seedlings during ditching, and the arc-shaped structure at the top of the stubble plate 23 achieves separation of seedlings to both sides while minimizing damage to the seedlings.

[0046] like Figures 4-7 As shown, the trenching mechanism 1 is further positioned below the contouring mechanism 2. Specifically, the trenching mechanism 1 has a contouring plate at its top, with mounting holes on the plate and mounting nuts below the mounting holes. Bolts connect the two mechanisms together through the mounting holes on the contouring plate. The trenching mechanism 1 includes a front-to-back trenching section 110 and a trench holding section 120. The front-to-back trenching section 110 has a V-shaped horizontal cross-section for trenching; the trench holding section 120 has a rectangular horizontal cross-section to prevent soil from falling back into the trench after trenching. The trench holding section 120 is connected to the fertilizer discharge mechanism 4. Furthermore, the connection point between the trench holding section 120 and the fertilizer discharge mechanism 4 is higher than that of the contouring mechanism 2 to prevent mud and water from entering and causing fertilizer to stick to the surface of the machine.

[0047] Furthermore, the tip groove portion 110 is gradually inclined backward from top to bottom. To better achieve the groove, the V-shaped angle θ formed by the horizontal cross-section of the tip groove portion 110 is 20°-30°. Specifically, the horizontal cross-section of the groove holding portion 120 is rectangular. The top and bottom surfaces of both the tip groove portion 110 and the groove holding portion 120 are horizontal, and the top surface of the groove holding portion 120 is used for fixed connection with the contouring base plate 21 of the contouring mechanism 2. Specifically, the top surface of the groove holding portion 120 is provided with a mounting plate for fixed connection with the contouring base plate 21; the tip groove portion 110 and the groove holding portion 120 are integrally molded, and a hollow sealed cavity is formed inside.

[0048] Furthermore, the fertilizer discharge mechanism 4 is located at the tail end of the trench holding part 120. The fertilizer discharge mechanism 4 includes a fertilizer inlet 410 connected in sequence, a material discharge plate 420 extending from below the fertilizer inlet 410 to the bottom of the trenching mechanism 1, and baffles 430 disposed on both sides of the material discharge plate 420. The material discharge plate 420 and the baffles 430 are integrally formed. The fertilizer inlet 410 is used to connect to the fertilizer discharge port of external agricultural machinery. A fertilizer discharge channel is formed between the material discharge plate 420 and the two side baffles 430. The space above the two side baffles 430 is open to form a gas dissipation channel. The external fertilizer mixture is transported to the fertilizer discharge channel through the fertilizer discharge port and the fertilizer inlet 410. The gas in the fertilizer mixture is discharged through the gas dissipation channel, and the fertilizer in the fertilizer mixture is discharged into the bottom of the trench through the fertilizer discharge channel. Specifically, the back of the trench holding part 120 is the material discharge plate 420, and the trench holding part 120 and the baffles 430 are integrally formed.

[0049] Furthermore, the length of the top of the baffle 430 is greater than the length of the bottom of the baffle 430, and the material drop plate 420 is gradually inclined from top to bottom towards the tail of the baffle 430, thereby gradually reducing the space enclosed by the baffle 430 and the material drop plate 420 from top to bottom. This arrangement is mainly to allow the fertilizer to fall at an angle and into the bottom of the ditch, and also to facilitate the escape of gas from the gas escape channel. When the material drop plate 420 is set vertically, the falling fertilizer is prone to splashing mud and water, causing the fertilizer to stick to the inside of the material drop plate 420 and / or the baffle 430, resulting in material blockage.

[0050] Specifically, the space near the material drop plate 420 forms a primary pressure relief channel A for airflow diffusion, and the space above the side baffles 430 is connected to the external airflow to form a secondary pressure relief channel B.

[0051] Furthermore, the bottom of the gas fertilizer inlet 410 is connected to the discharge plate 420, and a splash guard 440 is provided on the upper bottom of the gas fertilizer inlet 410 to prevent fertilizer in the gas fertilizer mixture from splashing out when it falls from the gas fertilizer inlet 410 to the discharge plate 420. The splash guard 440 is located on the upper edge of the two side baffles 430 and partially covers the space above the baffles 430.

[0052] like Figure 2 and Figure 8 As shown, the soil covering mechanism 5 is further disposed at the tail end of the fertilizer discharge mechanism 4, and the tail end of the fertilizer discharge mechanism 4 is also provided with a receiving plate 450 for receiving and fixing the soil covering mechanism 5. The receiving plate 450 is disposed on the upper edge of the tail end of the two side baffles 430, and the height of the tail end of the baffles 430 is lower than the height of the front middle part of the baffles 430. The receiving plate 450 and the baffles 430 are integrally formed.

[0053] Specifically, the soil covering mechanism 5 includes a flat plate 510 with a notch in the middle of its tail for draining mud and water. Two inclined plates 520 are respectively provided on both sides of the tail of the flat plate 510, extending downwards and outwards, forming an inverted V-shape with the tail of the flat plate 510 for soil covering. The head of the flat plate 510 is respectively mounted on a receiving plate 450 and a contoured base plate 21. The head of the flat plate 510 has a hanging ear 511 and a mounting hole 6. The hanging ear 511 is located on both sides of the head of the flat plate 510 for connecting with the contouring mechanism 2. The mounting hole 6 is located in the middle of the head of the flat plate 510 for connecting with the receiving plate 450 of the fertilizer discharge mechanism 4. The angle between the inclined plate 520 and the flat plate 510 is 90° to 145°. The flat plate 510, the inclined plate 520, and the hanging ear 511 are integrally formed.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation of the present invention.
