Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization and sowing, specifically to a single-pendulum double-nozzle spot-sowing fertilization pick. Background Technology

[0002] In traditional agricultural production, sowing and fertilization are usually two separate processes, which not only consume a lot of manpower and time, but also make it difficult to ensure the proper spacing between seeds and fertilizers, easily leading to seed burn. Although there are some integrated sowing and fertilization tools on the market, they have problems such as complex structure, inconvenient operation, and high cost. Especially for small farmlands or mountainous plots, large machinery is difficult to operate, and there is an urgent need for a simple and practical manual sowing and fertilization tool. Utility Model Content

[0003] The purpose of this invention is to provide a single-pendulum double-nozzle seeding and fertilization hoe that is simple in structure, easy to operate, and capable of separating seeds and fertilizers while automatically covering and compacting the soil, thereby improving agricultural production efficiency and reducing labor intensity. The specific technical solution is as follows:

[0004] The single-pendulum double-nozzle fertilizing pick of the present invention includes a pick head, a hollow pick handle, and a seed storage bottle. The pick head is fixedly connected to the hollow pick handle via the pick head handle, and the seed storage bottle is fixed on the hollow pick handle.

[0005] The pickaxe head includes a pickaxe head housing, a cover plate, a swing shaft, a swing body, and a torsion spring. The cover plate is located at the front of the pickaxe head housing, and the two together form a receiving cavity for accommodating the swing body. The pickaxe head housing has a fertilizer distribution chamber and a seed distribution port corresponding to the hollow pickaxe handle. The seed distribution port corresponds to the outlet of the seed storage bottle, and the fertilizer distribution chamber is connected to the hollow pickaxe handle through the pickaxe handle.

[0006] The pendulum shaft is supported on two side plates of the housing, and the torsion spring and pendulum are sleeved on the pendulum shaft. The pendulum has a seeding slot and a fertilizer dispensing slot. Under the preload of the torsion spring, the pendulum is at the top dead center position, at which time the seeding slot is aligned with the seeding port and the fertilizer dispensing slot is aligned with the fertilizer dispensing chamber.

[0007] The lower part of the pick head casing also has seed-dispensing and fertilizer-dispensing nozzles arranged side by side. When the pick head of the spot-seeding and fertilizing pick is raised to a certain height and then dropped into the soil, the pendulum swings to its lower stop point under the action of inertia. At this time, the seed-dispensing trough is aligned with the seed-dispensing nozzle, and the fertilizer-dispensing trough is aligned with the fertilizer-dispensing nozzle. The seed and fertilizer enter the soil under the action of inertia and gravity, realizing the side-deep application of base fertilizer and the automatic soil covering and compaction operation of separating seed and fertilizer.

[0008] Both the seed and fertilizer distribution troughs are equipped with sponges, and the amount of seeds and fertilizer can be changed by adjusting the size of the sponges.

[0009] Beneficial effects of this utility model

[0010] Simple structure: This invention achieves the separation and application of seeds and fertilizers through the swinging of the pendulum, eliminating the need for complex mechanical structures and reducing manufacturing costs and maintenance difficulties.

[0011] Easy to operate: Simply lift and lower the pickaxe, and the sowing and fertilizing process can be completed by using inertia, which reduces labor intensity and improves work efficiency.

[0012] Seed and fertilizer separation: The seed and fertilizer outlets are set up side by side, and the body is positioned at different locations to align with the seed outlet and fertilizer outlet respectively, ensuring that the seeds and fertilizer are kept at an appropriate distance and avoiding seed burning.

[0013] Automatic soil covering and compaction: After the pick enters the soil, soil covering is naturally formed, realizing automatic soil covering and compaction after sowing and fertilization, reducing manual operation steps.

[0014] Adjustable fertilizer application: By adjusting the size of the sponges in the seed and fertilizer distribution troughs, the amount of seed and fertilizer can be flexibly adjusted according to the needs of different crops. Attached Figure Description

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The purpose and effects of the present invention will become clearer as a result. Further detailed description of the present invention will be provided below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] As shown in the figure, the single-pendulum double-nozzle seeding and fertilization pick of the present invention is mainly composed of a pick head, a hollow pick handle (5) and a seed storage bottle (4).

[0022] The pickaxe includes a pickaxe housing 3, a cover plate 1, a pendulum shaft 23, a pendulum 2, and a torsion spring 22. The cover plate 1 is fixed to the front of the pickaxe housing 3 by bolts, forming a closed receiving cavity for accommodating the pendulum 2 and its related components.

[0023] The pickaxe head shell 3 has a fertilizer distribution chamber 38 and a seed distribution port 39 at the corresponding positions of the hollow pickaxe handle 5. The seed distribution port 39 is connected to the outlet of the seed storage bottle 4 via a pipe, and the seed storage bottle 4 contains seeds. The fertilizer distribution chamber 38 is connected to the hollow pickaxe handle 5 via the pickaxe head handle 37, and fertilizer can be placed inside the hollow pickaxe handle 5.

[0024] The two ends of the pendulum shaft 23 are respectively supported on the two side plates of the pick head housing 3. The torsion spring 22 and the pendulum 2 are sequentially sleeved on the pendulum shaft 23. One end of the torsion spring 22 is fixed to the pendulum 2, and the other end is fixed to the pick head housing 3, providing preload to the pendulum 2 to keep it at the top dead center position.

[0025] The pendulum 2 has a seed-distributing trough 25 and a fertilizer-distributing trough 26, both of which contain a sponge (not shown in the figure). When the pendulum 2 is at its upper stop position, the seed-distributing trough 25 is aligned with the seed-distributing opening 39, allowing seeds from the seed storage bottle 4 to fall into the trough 25 through the opening 39. The fertilizer-distributing trough 26 is aligned with the fertilizer-distributing chamber 38, allowing fertilizer from the hollow pickaxe handle 5 to fall into the trough 26 through the chamber 38. By adjusting the size of the sponge, the amount of seed and fertilizer falling into the seed-distributing trough 25 and fertilizer-distributing trough 26 can be controlled.

[0026] The lower part of the pick head shell 3 is provided with a seed-discharging nozzle 33 and a fertilizer-discharging nozzle 34 arranged side by side. When using the spot-seeding and fertilizing pick, fertilizer is first loaded into the hollow pick handle 5, and seeds are loaded into the seed storage bottle 4. Then, the pick head is raised to a certain height and then lowered to dig into the soil. At the moment the pick head falls, due to inertia, the pendulum 2 will overcome the preload of the torsion spring 22 and swing around the pendulum axis 23 to the lower stop position. At this time, the seed distribution trough 25 is aligned with the seed-discharging nozzle 33, and the fertilizer distribution trough 26 is aligned with the fertilizer-discharging nozzle 34. Under the action of inertia and gravity, the seeds in the seed distribution trough 25 and the fertilizer in the fertilizer distribution trough 26 enter the soil through the seed-discharging nozzle 33 and the fertilizer-discharging nozzle 34 respectively, realizing sowing and fertilization.

[0027] After one round of sowing and fertilization is completed, the sowing and fertilization pick is lifted, and the pendulum 2 returns to the upper stop position under the pre-tension of the torsion spring 22. The seeding trough 25 and fertilizer trough 26 are aligned with the seeding port 39 and fertilizer chamber 38 again to prepare for the next round of sowing and fertilization.

[0028] In addition, during actual use, the soil depth of the seed-producing duckbill 33 and fertilizer-producing duckbill 34, as well as the size of the sponge in the seed-distributing trough 25 and fertilizer-distributing trough 26, can be adjusted according to the planting needs of different crops to achieve the best sowing and fertilization effect.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
