Description

Technical Field

[0001] The invention relates to the technical field of forest cultivation, and in particular to a seedling antifreeze device for forest cultivation. Background Art

[0002] As plants, seedlings have their own natural growth patterns. In view of the role of greening and oxygen production in purifying the air, local governments and countries strongly advocate green cities. Therefore, the demand for seedlings is very large. Tree seedlings are seedlings with roots and trunks. All seedlings cultivated in nurseries, regardless of their age, are called seedlings before they are left the nursery. The temperature is low in winter, and many overwintering seedlings will be attacked by frost damage. If appropriate measures are not taken in time, it will affect the growth of seedlings next year.

[0003] Nowadays, when protecting seedlings from frost, workers usually tie insulation belts to the branches of the seedlings to keep the seedlings warm. However, the efficiency of manual bundling is extremely low, and the insulation effect of the insulation belts is also average, which leads to a decrease in the survival rate of the seedlings. In addition, the insulation belts will also have a certain restriction on the growth of the seedling stems. For smaller, unformed seedlings, it is not realistic to use insulation belts for insulation. Therefore, we propose a seedling antifreeze device for forest cultivation, which can perform batch insulation treatment on tree seedlings and has little effect on the growth and development of the seedlings.

DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 6 As shown, this embodiment proposes a seedling antifreeze device for forest cultivation, including a protective cover, a connecting component, a closing component and a heating mechanism. Compared with the antifreeze method of the seedlings using the insulation belt in the prior art, the present invention uses a spliced ​​protective cover to seal and protect the seedlings, and at the same time, the fan 501 is used to supply air to the interior of the heating box 401, and the air is heated by the heating wire 402. The hot air enters the interior of the protective cover to protect the seedlings from freezing and ventilation at the same time. The water pump 702 sprays water into the interior of the protective cover through the cleaning pipe 701 to flush the inner wall of the protective cover, and at the same time increases the humidity in the protective cover to ensure the healthy growth of the seedlings and achieve better antifreeze effect.

[0021] There are multiple groups of protective covers for protecting seedlings. The protective covers are made of transparent material. The size of the protective covers is adjustable. The protective covers include a bottom plate 101, an adjustment plate 102, a top cover 103 and a telescopic cover 104. Two bottom plates 101 are provided, and two adjustment plates 102 are provided. The adjustment plates 102 correspond to the bottom plates 101 one by one. The adjustment plates 102 and the bottom plates 101 are slidably connected. A slider is fixedly connected to the adjustment plate 102. A slide groove matching the slider is provided on the bottom plate 101. The threaded connection on the bottom plate 101 is useful. There are two top covers 103 for locking bolts for locking the adjusting plate 102. The top covers 103 correspond to the adjusting plates 102 one by one. The top covers 103 are fixedly connected to the adjusting plates 102. The telescopic covers 104 are fixedly connected between the two top covers 103. Through the sliding cooperation between the adjusting plates 102 and the bottom plates 101, the height of the protective cover can be adjusted to adapt to the protection of seedlings of different heights. Through the extension and retraction of the telescopic covers 104, the distance between the two bottom plates 101 can be adjusted to adapt to the protection of seedlings of different widths.

[0022] The connecting assembly is used to connect two adjacent protective covers. The connecting assembly includes a connecting plate 201 and a connecting bolt 202. The connecting plate 201 is fixedly connected to the base plate 101. The connecting plate 201 is located at the edge of the base plate 101. A through hole for the connecting bolt 202 to pass through is opened on the connecting plate 201. The connecting bolt 202 is used to connect the two connecting plates 201 that are in contact with each other between the two adjacent base plates 101. By connecting the connecting plates 201 with the connecting bolts 202, the two adjacent base plates 101 can be connected, multiple protective covers can be spliced ​​into a whole, the total length of the protective covers can be adjusted, and the entire row of seedlings can be protected as a whole.

[0023] Two closing components are provided, and the two closing components are respectively arranged on both sides of the multiple protective covers for closing the multiple protective covers. The closing components are made of transparent material, and the closing components include sealing plates 301. Two sealing plates 301 are provided, and the sealing plates 301 are connected to the bottom plate 101 through a connecting component. A telescopic cover 104 is fixedly connected between the two sealing plates 301, and a connecting plate 201 is also fixedly connected to the edge of the sealing plate 301. The sealing plate 301 is connected to the bottom plate 101 at both sides through the connecting plate 201, so that the sealing plate 301 and the protective cover form a relatively closed cover body, which provides closed protection for the seedlings and reduces the entry of cold air from the outside. The telescopic cover 104 is adapted to the width change of the protective cover through the telescopic movement to protect seedlings of different widths. The height of the sealing plate 301 is relatively high, and both sides of the protective cover can be better closed.

[0024] The heating mechanism is used to heat the interior of the protective cover. The heating mechanism includes a heating box 401, a heating wire 402 and an air supply assembly. The heating box 401 is fixedly connected to the interior of the bottom plate 101, and the heating wire 402 is installed in the interior of the heating box 401. The air supply assembly is used to supply air to the interior of the protective cover through the heating box 401. The air supply assembly includes a fan 501 and an air inlet network 502. The air inlet network 502 is connected to the heating box 401. A plurality of air outlets are provided on the heating box 401. The air inlet network 502 is connected to the air outlet of the fan 501. In order to improve the heating and heat preservation effect on the seedlings, the air inlet network 502 surrounds the outside of the heating box 401. Figure 5 As shown, the air outlet of the fan 501 is connected to a diverter box, and a plurality of air supply pipes 503 are connected to the diverter box. Valves are installed on the air supply pipes 503. The air inlet network 502 is connected to the corresponding air supply pipes 503 through a connecting pipe. Air is supplied to the interior of the air inlet network 502 through the fan 501, and the heating box 401 is heated by the heating wire 402. The air inlet network 502 and the heating box 401 are tightly attached to each other, so that the air in the air inlet network 502 can be preheated. The air inlet network 502 is partially in the shape of a pipe network and surrounds the outer wall of the heating box 401, thereby extending the residence time of the air in the air inlet network 502, so that the wind has a certain temperature when entering the heating box 401, and then the air in the heating box 401 is heated by the heating wire 402. The hot air enters the interior of the protective cover through the air outlet, and the interior of the protective cover is heated and anti-freezing, thereby protecting the seedlings.

[0025] In order to regulate the temperature inside the protective cover, a temperature sensor 1 is installed inside the adjustment plate 102. The temperature sensor 1 and the heating wire 402 are electrically connected. The temperature range of the temperature sensor 1 is pre-set. When the temperature is lower than the set temperature, the heating wire 402 is turned on to heat the inside of the protective cover. When the temperature is higher than the set temperature, the heating wire 402 is turned off to allow normal air to enter. The air in the protective cover is circulated through the fan 501, and the excess air flows out through the gap between the telescopic covers 104, so that the air environment in the protective cover is in a circulating state, thereby ensuring the normal growth of the seedlings.

[0026] In order to fix the position of the protective cover, it also includes a fixing component, which is arranged on the base plate 101 and is used to fix the protective cover. The fixing component includes a fixing plate 601, an insertion rod 602 and a pulling plate 603. The fixing plate 601 is fixedly connected to the base plate 101, the insertion rod 602 is slidably connected to the fixing plate 601, the bottom of the insertion rod 602 is pointed, and the pulling plate 603 is fixedly connected to the top of the insertion rod 602. The insertion rod 602 is inserted into the ground to fix the position of the protective cover to prevent the protective cover from tipping over in windy weather and ensure the protection of the seedlings. When the protective cover needs to be moved or disassembled, the insertion rod 602 is pulled out from under the ground through the pulling plate 603 to release the limit on the protective cover and disassemble the protective cover.

[0027] In order to clean the protective cover, a cleaning assembly is also included. The cleaning assembly is used to clean the inner wall of the protective cover. The cleaning assembly includes a cleaning pipe 701, a water pump 702 and a nozzle 703. The cleaning pipe 701 is installed on the top cover 103. The cleaning pipe 701 is connected to the water outlet of the water pump 702 through the water inlet pipe 704. A plurality of nozzles 703 are provided. The nozzles 703 are connected to the cleaning pipe 701. The cleaning pipe 701 can be rotatably arranged on the top cover 103. The nozzles 703 are tiltedly arranged on the cleaning pipe. The outside of 701, the top cover 103 is fixedly connected with a mounting frame, the cleaning pipe 701 is rotatably connected to the mounting frame, the water inlet pipe 704 is connected with the water inlet seat 705, the cleaning pipe 701 and the water inlet seat 705 are rotatably connected, the two corresponding water inlet seats 705 on the two top covers 103 in the same protective cover are connected through a telescopic hose, the water inlet of the water pump 702 is connected to tap water, a water tank or a reservoir, etc., the water outlet of the water pump 702 is also connected with a diversion box, and the diversion box is connected with a plurality of water delivery pipes 706, a valve is installed on the water supply pipe 706, and the water inlet pipe 704 is connected to the corresponding water supply pipe 706. Water is supplied to the inside of the cleaning pipe 701 through the water pump 702, and the water is sprayed into the inside of the protective cover through the nozzle 703. The nozzle 703 is tilted, and the reaction force of the water spraying outward drives the cleaning pipe 701 to rotate, thereby expanding the water spraying range of the nozzle 703. Part of the water is sprayed on the inner wall of the top cover 103 and the adjusting plate 102 to wash the inner wall of the protective cover, thereby reducing the pollution of the inner wall of the protective cover by fog or other dirt, and reducing the impact on the lighting of the seedlings. The dirt outside the protective cover can be washed off by rainwater, or the outside of the protective cover can be cleaned regularly by humans. It is laborious to use manual labor to clean the inside of the protective cover, and the protective cover needs to be disassembled. Therefore, the inside of the protective cover is cleaned through the cleaning pipe 701 and the nozzle 703, and the inside of the protective cover is humidified at the same time to avoid long-term heating causing dryness and water shortage in the growth environment of the seedlings, thereby ensuring the healthy growth of the seedlings.

[0028] It should be additionally explained that solar panels and batteries may be provided to utilize solar energy to power electrical components such as the fan 501 , the heating wire 402 , the water pump 702 and the temperature sensor 1 .

[0029] The working principle or use process of the seedling antifreeze device for forest cultivation is as follows: According to the overall growth and morphology of the seedlings, select a suitable number of protective covers, adjust the height of the adjustment plate 102 at the same time, tighten the locking bolts to fix the height of the adjustment plate 102, splice multiple protective covers through the connecting bolts 202 and the connecting plate 201, cover the outside of the seedlings with the protective covers, and connect the sealing plates 301 to both sides of the protective covers; The plug rod 602 is inserted into the ground, and the protective cover is used to seal and protect the seedlings. The fan 501 supplies air to the interior of the heating box 401 through the air inlet network 502, and supplies air to the interior of the protective cover through the air outlet. The temperature sensor 1 monitors the temperature inside the protective cover. When the temperature is low, the heating wire 402 is turned on to heat the air sent into the air inlet network 502, thereby protecting the seedlings from freezing. When the temperature rises to a certain amount, the heating wire 402 is turned off to maintain a suitable temperature for the growth of the seedlings. Water is delivered to the inside of the cleaning tube 701 through the water pump 702, and water is sprayed outward through the nozzle 703. At the same time, the cleaning tube 701 is rotated under the reaction force to expand the water spraying range. The sprayed water washes the inner wall of the protective cover and waters the seedlings at the same time to ensure the humidity inside the protective cover.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
