Description

Technical field:

[0001] The utility model belongs to the technical field of grape planting equipment, and in particular relates to a grape wintering insulation device, which is used to keep grapes warm in cold seasons or regions so that they can grow normally. Background technology:

[0002] Grapes are a crop that cannot tolerate low temperatures. When the ground temperature drops to -6°C in winter, the roots, stems, and branches of grapes will suffer varying degrees of frost damage. Therefore, winter management of grapes is crucial, as it affects the yield and quality of grapes the following year. Therefore, in winter, when ambient temperatures are low, they are usually buried in the soil for wintering. In the spring of the following year, because grape vines are typically secured with wire during their growth, the vines must be removed from the soil before being buried for wintering. After emerging in the spring, the branches must be dug out of the soil. This operation is not only time-consuming and labor-intensive, but can also easily damage the grape branches and rhizomes. There are many insulation devices in the prior art. For example, Chinese patent 201620447238.3 discloses a winter grape insulation shed, which includes a roof and a bracket, and also includes a floor heating device for heating the soil. The floor heating device includes a heating device, a temperature control device, a heat dissipation device and a recycling device. The heat dissipation device is a heat dissipation pipe including an inlet end and an outlet end. The inlet end is connected to the temperature control device, and the outlet end is connected to the heating device. The heat dissipation pipe is arranged in a "net" shape, and a branch pipe is provided on the heat dissipation pipe, and a heat dissipation head is provided on the branch pipe. The recycling device includes a collection tank arranged below the heat dissipation device, a filter screen is provided on the collection tank, and a recovery pipe is provided on the collection tank, and the recovery pipe is connected to the heating device. Chinese Patent 201520793391.7 discloses a grape insulation blanket comprising an inner layer and an outer layer, with the outer layer covering the outer surface of the inner layer. The inner layer is primarily composed of at least one layer of blended needle-punched felt, and the outer layer is primarily composed of at least one layer of PE film, which is fused to the outer surface of the inner layer by lamination or coating. The PE film is black. Chinese Patent 201020204711.8 discloses a steel-frame greenhouse for grape insulation and rain protection, comprising piles, galvanized steel pipes, angle steel, U-shaped hoops, V-shaped steel forks, wire mesh, and fasteners. The piles are spaced 3 meters apart, with every three piles connected by a 6-meter angle steel. The connection between the piles and the angle steel is secured with a U-shaped hoops. The individual grape racks are connected in series, and the galvanized steel pipes are connected with V-shaped steel forks and then bolted.Chinese Patent 200620102473.3 discloses a grape insulation rain shelter, which includes a double cross ￥-shaped frame composed of piles, lower beams, and upper beams. Each pair of ￥-shaped frames is connected by six hanging wires, two of which are fixed to the lower part of the piles, two of which are connected to the two opposite ends of the lower beam, and two of which are connected to the two opposite ends of the upper beam. The tops of the two piles are connected by a top wire. A bamboo bow is fixed to the top of the piles. The two ends of the bamboo bow are bent downward and connected by a bamboo bow fixing line. Each pair of ￥-shaped frames is evenly spaced. There are several bamboo bows distributed, and the two ends of each bamboo bow are connected by bamboo bow fixing lines. The top of each bamboo bow is fixed to the top steel wire, and the same side ends of each bamboo bow are connected by a longitudinal steel wire respectively. The grape insulation rain shelter array is connected in series and then arranged in parallel. The ends of adjacent bamboo bows in two adjacent rows are connected by transverse steel wires. Plastic film is fixed on the bamboo bows, and plastic film is also fixed on the transverse steel wire between the two rows of bamboo bows. The ends of the longitudinal steel wires are tilted outward and downward and fixed to the anchor stones buried in the ground. The ends of the top steel wire and the branch hanging steel wire are also tilted outward and downward and fixed to the anchor stones buried in the ground. However, it has a complex structure, is time-consuming to set up, and has a high economic cost, making it unsuitable for popularization and use. Therefore, it is necessary to develop and design a grape winter insulation device with a simple structure, simple to set up, and low cost. Summary of the invention:

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and develop a grape wintering insulation device, which is formed by a simple plug-in connection method, thereby improving efficiency and reducing cost.

[0004] In order to achieve the above-mentioned purpose, the main structure of the grape wintering insulation device involved in the present invention includes an array of brackets connected by cross bars;

[0005] The bracket 1 is composed of a hollow circular tube and three legs. The circular tube is located at the top. The top ends of the legs 12 are welded to the circular tube and the bottom ends are separately plugged into the ground. The angles between adjacent legs are 120 degrees.

[0006] The cavity of the round tube is used for passing the cross bar.

[0007] When the grape wintering heat preservation device of the utility model is used:

[0008] First, several supports are inserted into the grape planting area, and crossbars are inserted into the round tubes of two adjacent supports;

[0009] Then, run the heating cables between the legs and connect all the heating cables to the temperature controller;

[0010] Finally, lay the insulation film on the crossbar, bury the edge of the insulation film with soil, and then lay the insulation blanket on the outside of the insulation film;

[0011] The heating cable adopts air heating mode and is placed on the ground. The heating cable is powered to dissipate heat, and the insulation film reflects heat on its mirror surface.

[0012] Compared with the prior art, the utility model is composed of a bracket formed by welding legs and circular rings, and a cross bar and a bottom bar connecting the top and bottom ends of the bracket. The greenhouse frame is erected in an assembly manner, which saves time and effort. When in use, it is only necessary to lay heating cables inside the greenhouse frame and lay insulation film and insulation quilts on the outside in sequence to complete the erection of the insulation greenhouse in a short time. In winter, the heating temperature of the heating cable is controlled by a temperature controller, and the double-layer protection of the insulation film and insulation quilt can prevent wind and rain as well as keep out cold and keep warm, and the insulation effect is better. Description of the drawings:

[0013] Figure 1 It is a front schematic diagram of the main structure of the utility model. Specific implementation method:

Several brackets 1 are arranged in an array according to the size of the grape planting area, and the circular tubes 11 of two adjacent brackets 1 are connected by a cross bar 2.

[0017] The height of the brackets 1 involved in this embodiment is set according to the height of the insulation greenhouse, the number is set according to the area of ​​the insulation greenhouse, and the distance is set according to the planting density of the grapes; the length of the crossbars 2 is set according to the distance between the brackets 1.

[0018] The specific process steps for using the grape wintering insulation device involved in this embodiment are as follows:

[0019] First, several brackets 1 are inserted into the grape planting area, and crossbars 2 are inserted into the circular tubes 11 of two adjacent brackets 1;

[0020] Then, lay heating cables between the legs 12 and connect all heating cables to the temperature controller;

[0021] Finally, a thermal insulation film is laid on the cross bar 2, and the edge of the thermal insulation film is extended to the support leg 12 of the outermost ring bracket 1. The edge of the thermal insulation film is buried with soil, and then a thermal insulation quilt is laid on the outside of the thermal insulation film. The main structure of the thermal insulation quilt is windproof cloth, silk cotton, pearl cotton and reflective material from top to bottom, which can better prevent wind and store heat.
