Description:
BACKGROUND 
     Technical Field 
     The present invention relates to a device for the frost prevention machine column, which relates to a fixed device and method of a stand column of the frost prevention machine used in tea (fruit) garden, which belongs to the technical field of agricultural machinery. 
     Description of Related Art 
     China has a long history of tea planting and drinking. The growth and development of tea trees requires a warm and moist climate. The germination of tea buds in early spring is easy to be affected by cold spell in later spring, which reduces quality and production of the tea. In recent years, research on tea tree defrosting technology has been carried out rapidly in China. The research shows that frost prevention effect can be achieved by using the frost prevention machine to conduct airflow disturbance from top to bottom. 
     At present, commonly used methods for fixing the frost prevention machine column are as below. (1) Manual digging a pit with a certain depth in a location where the frost prevention machine is installed. Pouring concrete in the pit, and a top of the concrete is provided with an anchor bolt. A column bottom flange is fixed on a foundation of the concrete by the anchor bolt. The disadvantage of this method is that labor intensity is high and installation efficiency of the frost prevention machine is low. (2) Use tools to dig a pit with a certain depth and a diameter slightly bigger than a diameter of the column in a location where the frost prevention machine is installed. The frost prevention machine column is placed in the pit with a body of the column being kept upright, and is buried via filling of soil or concrete after adjusting the direction. The disadvantage of this method is that: in order to guarantee working requirement of the column, the pit can only has the diameter slightly bigger than that of the column, such that in late burying, a gap between soil and column is hard to eliminate. The gap will further increase due to vibration and wind generated from frost prevention machine in the process of using machine, this severely reduces safety of using the frost prevention machine and work efficiency. To solve the problem of high labor intensity and low efficiency of digging the pit, the present invention provides the pedestal plate punched into the soil to replace the deep pit fixing frost prevention machine, which greatly reduces the labor intensity and improves the installation efficiency of the frost prevention machine. In addition, Chinese utility model patent CN201120394200.1 discloses a fixing device for a stand column of the frost prevention machine for plant, which includes several root stand institutions disposed at a bottom of the stand column. The root stand mechanisms include a steel root beam formed by a metal sheet beam transversely bent into trough type, and a U-shaped hoop. A pair of positioning rods is disposed on a middle of the steel root beam. A lower part of the column is positioned between a bunch of positioning rods, which are fixed vertically to the steel root beam through the U-shaped hoop. This method requires digging bigger and deeper pits, which increase the labor intensity and requirement of installation of the device itself is high and cost is relatively high. The common feature of the above method is that it is necessary to dig a small diameter and high precision deep pit in the installation position of frost prevention machine, and it is labor intensive, time consuming and costly. The present invention adopts the method of driving the pedestal plate to insert into the soil to avoid the work of digging deep pits, thus it reduces the labor intensity, and improves the installation efficiency of the frost prevention machine columns. The height of frost prevention machine to the ground needs to reach 6.7 meters to meet the frost prevention effect of the frost prevention machine. Non-standard pipe is adopted in the conventional frost prevention machine column since the standard length of the pipe is 6 meters, which has a high cost. The use of the connecting support provided by the present invention can make the frost prevention machine column adopt standard pipe material, which can save 50% of the fabricating cost.

     The structure, functionality, and processing of the present invention are further described below with reference to the accompanying drawings and the concrete implementation examples. However, claimed scope of this present invention includes but not limited to that. 
     A fixed support for frost prevention machine with a side extending plate at bottom according to the present invention can overcome difficulties of the high precision of digging aperture, deep pit with a small diameter and the backfill compaction in the commonly used fixed installation methods of the frost prevention machine by punching the pedestal into the soil, and reduces the labor intensity and improves installation efficiency. The use of connecting support enables the standard pipe can replace the conventional non-standard pip, which was originally used to meet a height of the frost prevention machine, thereby greatly saving the fabricating costs, and facilitating transportation and storage. The side extending plate  36  at a bottom of the pedestal plate  31  extends outward, which increases the stability of the frost prevention machine fixed support. The hole in the pedestal plate connects the soil inside and outside of the pedestal into a whole, which enhances the stability of the pedestal and reduces the damage to the soil. The present invention provides a device which can be used for fixing the stand column of the frost prevention machine, especially suitable for using in land with few stone. 
     The installation process of the frost prevention machine is as follows. Firstly, dig a shallow pit in a corresponding installation position. Secondly, the pedestal plate  31  is spliced together and formed. Thirdly, each pedestal plate  31  is punched into the soil with a certain depth successively after location of each pedestal plate  31  is determined. Fourthly, when the upper end of the lower hole  35  is close to the ground, the connecting ring will be stuck into the lower hole  35  of each pedestal plate  31 . Fifthly, continues punching until the upper hole  34  is close to the ground, and the connecting ring attaches the upper hole  34  of each pedestal plate  31 . Then, the side extending adjusting rob  32  is struck downward. When the side extending adjusting rob  32  is moved downward, the wedge-shaped tip pushes the side extending plate  36  outward, and the side extending adjusting rob  32  is lowered by a certain distance (about 55 mm). An oblique thrust of the side extending adjusting rob  32  will no longer act to push the side extension plate  36  outward. At this time, a first projection of the side extending adjusting rob  32  moves downward to a first projection of the side extending plate  36 , which will continue to extend the side extending plate  36  outward, thereby reinforcing the frost prevention machine. When the first projection of the side extending adjusting rob  32  no longer acts to push the side extending plate  36  outward, a second engagement groove of the side extending adjusting rob  32  just moves downward to a second projection of the side extension plate  36 . From the beginning, continue to extend the side extensions  36  to enhance anti-dumping and stabilizing performance of the anti-frost machine. An upper end hole of the side extending adjusting rod  32  is aligned with the corresponding hole on the pedestal plate  31 , and the bolt is installed in the hole to fix the side extending adjusting rod  32  and the pedestal plate  31 . The side extending plate  36  is outwardly deployed and the side extending adjusting rob  32  has a groove which cooperates with the projection on the side extending plate  36 . Under the action of the upper end bolt connection of the side extending adjusting rod  32 , the position of the side extending plate  36  is fixed. After the installation of the pedestal  3  is completed, the connecting support  2  is fixed on the pedestal  3  by using the pedestal bolt  33  in a symmetrical installation method. Finally, the frost prevention machine column  11  is put on the anti-tilting guide barrel  21 , and the anti-tilting guide barrel  21  and the frost prevention machine column  11  are fixed by the means of plug welding. 
     The embodiment of the preferred implementation manners of this present invention, however, this present invention includes but not limited to the foregoing implementation manners. Any obvious improvements, replacements or variations that can be made by a person skilled in the art without departing from the substantial content of the present invention fall within the protection scope of the present invention.
