Generally, at least two labors are required to cooperate to complete the work. Not only is the labor intensity high and the efficiency is low, but also manual The holes dug are of different sizes and depths, and do not utilize the effective implementation of standardized production techniques. In recent years, although a variety of tobacco seedling transplanting machines have been developed in China, such as the technology disclosed in the patent No. CN201020694791.X and CN201020041259.8, this type of equipment has a complex structure and powerful functions, but it is relatively suitable for flat and open plains For regional use, it is difficult to carry for mountainous areas, which is not conducive to popularization. Therefore there have been many simple tobacco seedling transplanters. For the tobacco seedling transplanter disclosed in CN 202444767 U with the publication number, there are the following problems: 1. The hole-opening shovel is a two-piece movable structure. When opened, It is difficult to ensure that the force on both sides is even, so one side is not opened, and the other side is opened at a large angle. If the opening opened by the hole opener is not as large as the diameter of the seedling tube, it will affect the smoke. The fall of the seedlings causes interference. At the same time, when the transplanter is lifted, it will also scratch the immature tobacco seedlings, and even lift the fallen tobacco seedlings, which greatly reduces the work efficiency; , if they are processed separately, it will be laborious and time-consuming, which also affects work efficiency.

A return spring is connected between the middle part of the return control handle and the outer wall of the cylinder. When the fixed cone head and the movable cone head are closed, a cone with the tip facing down is formed. Body, when the fixed cone head and the movable cone head are opened, the inner diameter of the opening at the lower end of the fixed cone head and the movable cone head is not less than the inner diameter of the outer cylinder.

The tobacco seedling transplanter adopting the above-mentioned technical scheme can utilize the conical barrel formed by the closure of the fixed cone head and the movable cone head to punch holes. Since the hole opener is composed of a fixed fixed cone head and a movable movable cone head, there Worried about the uneven force on both sides of the hole opener, by holding the return control handle tightly, the moving cone head is pulled apart by the connecting rod, so that the tobacco seedlings can enter from the opened hole opener through the tobacco seedling channel In the hole, while the outline of the outer wall of the fixed cone coincides with the outline of the outer wall of the smoke seedling tube. Lifting after opening will not affect the planted tobacco seedlings. After letting go of the return control handle, the moving cone will close with the fixed cone under the action of the return spring.

For the fixed root water spraying process: under normal conditions, the upper valve body is opened and the lower valve body is closed. The distance between the valve bodies determines the quantity of fixed root water output. When in use, the upper linkage rod and the lower linkage rod rotate in a certain direction driven by the longitudinal linkage rod until the lower valve body opens, and the upper valve When the body is closed, the fixed-root water between the upper valve body and the lower valve body flows out through the opened lower valve body, and the upper valve body can prevent the fixed-root water in the water storage chamber from entering the quantitative pipe after the upper valve body is closed; After spraying, adjust the vertical linkage rod, the upper linkage rod and the lower linkage rod rotate in reverse under the drive of the longitudinal linkage rod, so that the upper valve body is opened and the lower valve body is closed. At this time, the fixed root of the water storage chamber Water is replenished to the metering tube again, waiting for the next root water spraying. It can be seen that the amount of each spray is determined by the volume between the upper valve body and the lower valve body, and the purpose of quantitative spraying root water is achieved.

It is further defined that when the hole opener is opened, the contour of the outer wall of the movable cone coincides with the contour of the outer wall of the outer cylinder. If the movable cone head is opened too far, the hole opener will be easily resisted by the soil when it exits the hole. Therefore, the outer wall contour of the movable cone head should preferably coincide with the outer wall contour of the outer cylinder, so that the hole exit is more labor-saving.

It is further defined that the upper valve body and the lower valve body are ball valves, and the length of the upper linkage rod is smaller than the distance between the upper valve body and the lower valve body. The use of ball valves is beneficial to control the opening and closing of the upper valve body and the lower valve body through the 90° rotation of the linkage assembly, and limiting the length of the upper linkage rod to be less than the distance between the upper valve body and the lower valve body can avoid the rotation process of the linkage assembly interference in.

Compared with the prior art, the utility model can avoid the situation that the tobacco seedlings do not fall and the tobacco seedlings go out of the hole with the hole opener, and on the basis of the tobacco seedling transplanting device that can complete the hole digging and seedling placement, an additional device that can The device for spraying fixed root water avoids the process of artificially replenishing fixed root water, which is convenient for one person to complete the work and improves work efficiency.
