AI Technical Summary
In the production of existing cigar leaf, the conical punching head used in the fertilizer punching device causes the fertilizer hole to be small, the local fertilizer concentration is high, which can easily cause root damage, and the fertilizer dissolution is insufficient, affecting the growth and development of tobacco plants and the efficiency of nutrient utilization.
A cigar leaf fertilizer driller is designed, with a long rectangular cross-section of the punching shovel. The holes in the fertilizer are expanded through the open-closed punching shovel and the cross-hinged rod arm structure to ensure the appropriate local fertilizer concentration, and through the tip and hole depth limit plate with a gradient from top to bottom, avoiding excessive drilling and nutrient residue.
Effectively expand the holes in the fertilizer, ensure that the fertilizer is fully dissolved and absorbed, reduce nutrient residue, promote the normal growth and development of tobacco plants, and improve the fertilizer utilization efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco leaf planting, in particular to a cigar tobacco leaf fertilizer puncher. Background Art
[0002] Fertilization is an important part of cigar tobacco production. During the production process of cigar tobacco, fertilizer is applied five times. The first time is to apply furrow fertilizer before transplanting, and cover the ground with film after dry application and wait for planting tobacco seedlings; the second time is seedling fertilizer, which is applied in liquid form about 5-7 days after planting; the third time is seedling fertilizer, which is applied in liquid form about 15 days after planting; the fourth time is topdressing, which is applied in liquid form or dry form about 25 days after planting; the fifth time is dry application of fertilizer before 35 days after planting, using a puncher to apply fertilizer between plants and then cover with soil.
[0003] At present, the last topdressing in cigar tobacco production is to use a hole puncher to punch holes between plants, and then apply fertilizer and cover the soil. The hole puncher uses a conical punching head. Although this punching fertilization method improves the efficiency of fertilizer application, the fertilizer holes are small, and the local fertilizer concentration is often high, which can easily cause root damage and affect the growth and development of tobacco plants. In addition, the fertilizer holes are small, the amount of rainwater received is limited, the fertilizer is not fully dissolved, and it is not easy to be fully absorbed by the tobacco plants, which will cause excessive nutrient residues and affect the full utilization of nutrients. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a cigar tobacco leaf fertilizer puncher with a novel structure and reasonable design, which can effectively expand the fertilizer entry holes, ensure appropriate local fertilizer concentration, not easily cause root damage, and promote the normal growth and development of tobacco plants.
[0005] The utility model is implemented by the following scheme: a cigar tobacco leaf fertilizer puncher, comprising an openable and closable punching shovel, the punching shovel has a long rectangular cross-section, the punching shovel is composed of a left shovel shell and a right shovel shell, a first lever arm and a second lever arm for controlling the opening and closing of the punching shovel are arranged above the punching shovel, the first lever arm and the second lever arm are cross-hinged, and the lower ends of the first lever arm and the second lever arm are fixedly connected to the left shovel shell and the right shovel shell respectively.
[0006] Furthermore, the bottom of the punching shovel is provided with a pointed portion whose width gradually decreases from top to bottom.
[0007] Furthermore, a hole depth limiting plate is provided on the left or right side of the punching shovel, and the hole depth limiting plate is connected to the lower part of the first lever arm or the second lever arm through a connecting rod.
[0008] Furthermore, the first lever arm and the second lever arm are both fixedly connected with an operating handle.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a novel structure and a reasonable design, can effectively expand the fertilizer entry holes, ensures that the local fertilizer concentration is appropriate, is not easy to cause root damage, and promotes the normal growth and development of tobacco plants; at the same time, it can effectively increase the amount of rainwater received, the fertilizer is fully dissolved, the tobacco plants fully absorb nutrients, effectively reduce nutrient residues, and improve fertilizer utilization efficiency.

[0015] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0016] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0017] like Figures 1 to 3As shown, a cigar tobacco leaf fertilizer puncher includes an openable punching shovel 100, the cross section of the punching shovel is a long rectangle, the punching shovel 100 is composed of a left shovel shell 110 and a right shovel shell 120, and a first lever arm 200 and a second lever arm 300 are arranged above the punching shovel 100 to control the opening and closing of the punching shovel, the first lever arm and the second lever arm are cross-hinged, and the lower ends of the first lever arm and the second lever arm are fixedly connected to the left shovel shell and the right shovel shell respectively. The utility model puncher improves the traditional conical punching head and changes it to a punching shovel with a long rectangular (long strip) cross section, which enlarges the fertilizer entry hole, the local fertilizer concentration is appropriate, it is not easy to cause root damage, and promotes the normal growth and development of tobacco plants; the amount of rainwater received is increased, the fertilizer is fully dissolved, the tobacco plants fully absorb nutrients, the nutrient residue is effectively reduced, and the fertilizer utilization efficiency is improved.
[0018] In this embodiment, the bottom of the punching shovel is provided with a tip 130 whose width gradually decreases from top to bottom, so as to ensure that the punching shovel 100 is easy to insert into the soil. The length of the long rectangular cross section of the punching shovel is 10-15 cm and the width is 2-5 cm.
[0019] In this embodiment, a hole depth limit plate 400 is provided on the left or right side of the punching shovel.
