Problems solved by technology

But at present, in terms of the key cultivation technology of hole sealing, there is a lack of corresponding equipment and agricultural machinery and tools, and it is mostly done by manual shoveling. Damage to seedlings can easily lead to the occurrence and prevalence of viral diseases and other diseases
[0004] For tobacco seedlings or other high-value crop seedlings planted in holes, there is no special or special hole sealing device at present. Most of them use two simple tools to seal holes. The soil is dug down to fill the seedling hole. On the one hand, this method of sealing the hole is easy to damage the structure of the hole, which is labor-intensive and time-consuming, and the efficiency is low. Moreover, the amount of sealed soil is small, which easily leads to low quality of the hole sealing and affects the rooting of tobacco seedling crops. fast long
Another method uses a shovel to shovel the soil to seal the hole, which requires another person to hold the tobacco seedlings in a cage to prevent the damage to the seedlings during the sealing operation. On the one hand, the hole sealing is uneven, the work efficiency is low, and it is very easy. Tobacco virus disease is transmitted due to operational contact; on the other hand, improper operation of sealing holes and covering soil can easily cover the new leaves and growth points of young seedlings, inhibiting the normal growth and development of tobacco seedlings

Embodiment 1

[0027] A precision hole sealing device for transplanting tobacco crop seedlings, used for sealing holes after transplanting tobacco seedlings, its structure includes a head 10 and a connecting rod 20, the head 10 includes an outer cylinder 101 and The inner cylinder 102 inside; the outer cylinder 101 is a truncated conical shape with top and bottom openings, and the top area is larger than the bottom area; the inner cylinder 102 is a truncated conical shape with both top and bottom openings, and the bottom area is larger than the top area; The cylinder 102 and the outer cylinder 101 are nested inside and outside, and the gap formed is characterized by the fact that the top is larger than the bottom, which can facilitate the insertion of fine soil. At the same time, the area of ​​the bottom of the inner cylinder 102 is larger than the top, so that the inner cylinder 102 is at an inclined angle, which is convenient for the fine soil to slide into the hole. Inside the body; the in...

Embodiment 2

[0030] This embodiment has the same structure as Embodiment 1 except the following features:

[0031] Such as figure 1 , 2 As shown, the outer cylinder 101 and the inner cylinder 102 are two half-barrel bodies hinged in the vertical direction through movable hinges, and the hinged positions are located on the same side; through the connecting rod 20 and the handle 30, the inner cylinder 102 and the inner cylinder 102 can be controlled. The outer cylinder 101 opens and closes at the same time. For larger tobacco seedlings or larger holes, the head 10 needs to be enlarged. The inner cylinder 102 and outer cylinder 101 are controlled to open through the handle 30. For smaller tobacco seedlings, the inner cylinder 102 and the outer cylinder 101 are opened. The outer cylinder 101 can be closed by the handle 30 . The hole sealing device described in this embodiment can be adjusted in good time according to the size of the tobacco seedlings and the hole body.

Embodiment 3

[0033] This embodiment is identical in structure with Embodiment 2 except the following features:

[0034] Such as image 3 As shown, the handle is ear-shaped similar to the handle of scissors, and the end is provided with a hollow hand grip, which is convenient for holding and sealing acupoints.

Abstract

The invention discloses an accurate pit sealing device for transplanting seedlings of tobacco crops and belongs to the field of pit covering machines used for planting. The accurate pit sealing device is used for solving the problems that no special pit sealing equipment exists in the prior art, the manual pit sealing efficiency is low, diseases are spread easily, and pits are damaged easily. The accurate pit sealing device comprises a head and connecting rods. The head comprises an outer cylinder with openings formed in the upper portion and the lower portion respectively, and an inner cylinder arranged in the outer cylinder, wherein an opening is at least formed in the bottom end of the inner cylinder. The outer wall of the inner cylinder is fixedly connected with the inner wall of the outer cylinder through supporting rods. One ends of the connecting rods are fixed to the outer cylinder, and handles are arranged at the other ends of the connecting rods. The pit sealing device can protect tobacco seedlings better, make fine soil make contact with the tobacco seedlings as less as possible or not make contact with the tobacco seedlings, and reduce damage to the tobacco seedlings and disease infection caused by contact; the steps of manually removing the fine soil attached to the tobacco seedlings and the like are omitted, labor can be saved, the pit sealing efficiency and quality are improved, and root development and fast growth of the tobacco seedlings are guaranteed.

Description

technical field [0001] The invention relates to the field of machinery used for covering pits after planting small seedlings of economic crops, in particular to a hole sealing device for transplanting small seedlings of tobacco crops. Background technique [0002] Hole cultivation technology is mainly to form a microenvironment suitable for the growth and development of seedlings by digging or drilling holes in the plow layer or ridges during the cultivation process of crop seedlings, and to realize deep planting and improve light, temperature, water, and soil resources. The utilization rate can promote the development of the underground root system and the growth of the aboveground part of the crop, so as to achieve the purpose of rapid seedling growth and early growth. At present, in high-value economic crops such as tobacco, cotton, vegetables, flowers, etc., the cultivation method of single plant hole cultivation is more common. Due to the effects of natural resources s...
