Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tea tree planting equipment, and in particular relates to a cold-resistant and temperature-increasing device for tea seedlings in high-altitude tea areas during the winter. Background Art
[0002] China's tea culture has a long history. Tea is used as both food and special beverage. Tea contains tea polyphenols, tea pigments, theanine and other trace elements, which have health benefits such as anti-oxidation, anti-aging, and enhanced memory and learning ability. Therefore, tea is an important economic crop in my country. When the tea trees are in the seedling stage in the first two years, they must be protected from the sun and cold, especially those planted in high-altitude mountainous areas. The temperature is low in winter, the temperature difference between day and night is large, and they are prone to freezing. It is necessary to lay grass in the tea field or cover the tea seedlings with a warm cover. Laying grass in the tea field can maintain the soil temperature and prevent the soil from cooling down too quickly, but the tea seedlings are still easily frozen when encountering rain, snow and frost; covering the tea seedlings with a thermal cover can help the tea seedlings effectively resist rain, snow, wind and frost, but when the frost and snow are heavy, the thermal cover is easily crushed and the tea seedlings are damaged. When the weather is clear, the thermal cover needs to be removed to allow the tea seedlings to breathe and transmit light. Therefore, the thermal cover needs to be covered and removed in time according to the weather conditions. The current thermal covers are not convenient enough when covering and removing, and require more manpower, material resources and time. In addition, the structural strength is not easy to resist heavy frost and snow, and it is easy to be crushed, which brings inconvenience to the management of the tea garden. Utility Model Content
[0003] The utility model aims to solve the deficiencies of the prior art and provide a device for increasing temperature and resisting cold during winter for tea seedlings in tea areas at high altitudes.
[0004] The utility model is realized by the following technical solutions:
[0005] A device for overwintering cold-resistant and warming tea seedlings in high-altitude tea areas, comprising two front and rear groups of brackets with the same structure, a cross bar, a fan, a heat exchanger and a blow pipe that are connected in sequence, each group of brackets is composed of the upper parts of two support rods cross-hinged and connected, the two support rods of the brackets can rotate relative to each other along the upper hinge points, the tops of the two groups of brackets are detachably connected to the two ends of the cross bar to form a support frame structure, a thermal insulation film is provided between the support rods on the same side of the front and rear groups of brackets, a plurality of pull rings are symmetrically provided on both sides of the thermal insulation film, the pull rings are sleeved on the support rods and can slide up and down along the support rods, the top two sides of the thermal insulation film are fixedly connected to the upper part of the support rod, the bottom two sides of the thermal insulation film are provided with hanging rings, the upper part of the support rods is provided with hooks matching the hanging rings, and the blow pipe is laid on the tea garden ground below the brackets.
[0006] Furthermore, the blowing pipe is provided with a plurality of air outlet holes.
[0007] Furthermore, the bottom of the support rod is provided with a footing that can be inserted into the soil.
[0008] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model sets up two sets of front and rear brackets across the two ends of the tea ridge, and strengthens the structural strength of the brackets through cross rod connection, which is easy to install. The thermal insulation film installed on the bracket can keep the tea seedlings warm. The thermal insulation film can be folded or put down by moving the pull ring along the support rod. The operation is simple and easy. When it is put down, it can help the tea seedlings to withstand rain, snow and frost. When it is folded up, the tea seedlings can be ventilated and light-permeable. When the weather changes, only the thermal insulation film needs to be folded or put down without disassembling the bracket. It can not only help the tea seedlings to withstand low temperatures, but also is easy to operate, saving manpower, material resources and time. 2. In extremely low temperature weather, the utility model can turn on the fan and the heat exchanger, and blow hot air to the tea garden through the blow pipe to increase the temperature, which can not only prevent the tea seedlings from freezing, but also quickly melt the frost and snow on the thermal insulation film, and prevent the thermal insulation film from being crushed to damage the tea seedlings.

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited by the embodiments. Example 1
[0012] like Figure 1As shown: A device for warming tea seedlings in winter in a high-altitude tea area, comprising two groups of front and rear brackets 2 with the same structure, a cross bar 3, a fan 7, a heat exchanger 6 and a blow pipe 11 connected in sequence, each group of brackets 2 is composed of two upper parts of two support rods 1 cross-hinged and connected, the two support rods 1 of the bracket 2 can rotate relative to each other along the upper hinge point, the two support rods 1 of the bracket 2 are opened and erected across the two sides of the tea ridge, the footing 9 at the bottom of the support rod 1 is inserted into the soil to fix the bracket 2, the tops of the front and rear two groups of brackets 2 are detachably connected to the two ends of the cross bar 3 to form a support frame structure, according to The distance between the two groups of brackets 2 is selected to be connected by a cross bar 3 of appropriate length. If the tea ridge is long and has a certain curvature, multiple support frames can be connected to each other to cover the tea ridge. After the support frames are built, the openings at the front and rear ends can be blocked by baffles to prevent the front and rear ventilation from lowering the temperature. A thermal insulation film 10 is provided between the support bars 1 on the same side of the front and rear groups of brackets 2. The thermal insulation film 10 is made of black plastic. A plurality of pull rings 5 are symmetrically provided on both sides of the thermal insulation film 10.
