[0016] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0017] 1. This greenhouse insulation device, when the second connecting column reciprocates, by connecting the second connecting column and the connecting long rod, the connecting long rod is also reciprocated, by connecting the movable column to the connecting long rod, the outer sleeve of the movable column is connected to the grooved sleeve column, the top of the grooved sleeve column is connected to the heater, the movable column is driven to move by the movement of the connecting long rod, and the movement of the movable column drives the movement of the grooved sleeve column, and the movement of the grooved sleeve column drives the movement of the heater connected to the top of the grooved sleeve column. Through the reciprocating motion of the heater, when the heater delivers warm air to the greenhouse, the delivered warm air can be evenly supplied from front to back to the entire greenhouse through the linear back and forth motion of the heater, avoiding the problem of excessive local temperature caused by the warm air always being delivered to a certain place in the greenhouse, so that the warm air in the planting insulation greenhouse can be evenly covered from front to back, reducing the temperature difference between the front and back corners of the planting insulation greenhouse.

[0018] 2. This greenhouse insulation device rotates 90 degrees by connecting the long rod, driving the movable column fixedly connected to the connecting long rod to rotate 90 degrees. A cylindrical protrusion is arranged on the movable column, and a grooved sleeve column is connected to the outer surface of the cylindrical protrusion. By limiting the movable trajectory of the cylindrical protrusion in the spiral groove on the grooved sleeve column, when the cylindrical protrusion rotates 90 degrees, the spiral groove is driven to perform a spiral upward or downward movement. The upper surface of the grooved sleeve column is fixedly connected to the heater, and the heater rises or descends under the drive of the grooved sleeve column, so that the heater can move up and down when delivering warm air, so as to ensure that the upward warm air delivery in the vertical space of the planting insulation shed is uniform, and avoid the concentrated delivery of warm air at a certain height. At the same time, when the planting heights of fruits and vegetables are different, the up and down air supply of the heater can also achieve the goal that fruits and vegetables at different heights can be covered by warm air.

[0019] 3. This greenhouse insulation device, through the reciprocating motion of the first movable mechanism, drives the reciprocating motion of the heating mechanism connected to the first movable mechanism, so that the heater in the heating mechanism performs reciprocating motion, so that each heater will not always supply air at a fixed point. After a long period of blowing, the fruits and vegetables blown by the fixedly delivered warm air have the risk of being partially dried by high temperature on the leaves and other parts of the fruits and vegetables. The linear reciprocating air supply of the heater keeps the air supply of the heater in a moving state, and the phenomenon of excessive local temperature caused by fixed-point air supply will not occur.

[0020] 4. This greenhouse insulation device completes the forward and backward movement of the heater in the planting insulation greenhouse by setting the first movable mechanism, and transmits the swing of the connecting pin A to the swing groove by setting the movable end A and the movable end B in cooperation with the connecting piece. By setting one end of the rocker arm on the swing groove, the swing is transmitted to the swing groove, and then the spiral rising or falling action of the heater is completed by the rocker arm, ensuring that the heater can rotate while supplying air up and down in the vertical space. The warm air flow is gentler on fruits and vegetables, avoiding damage to the leaves of fruits and vegetables and other parts caused by direct blowing.

[0021] 5. This greenhouse insulation device drives the heating mechanism to perform upward reciprocating motion in the horizontal space through the extension and contraction of the first movable mechanism, and drives the heating mechanism to spirally rise and fall in the vertical space through the second movable mechanism. The forward and backward movement and up and down movement of the heating mechanism in the planting insulation shed ensures uniform temperature rise in the entire planting insulation shed, avoiding local overheating or local low temperature.

[0053] Working principle:

[0054] In the first step, the planting insulation shed 1 has an insulation effect. In modern fruit and vegetable planting technology, the insulation effect of the planting insulation shed 1 can be used to achieve off-season fruit and vegetable planting. However, when extreme abnormal weather causes the temperature in the planting insulation shed 1 to be lower than the suitable temperature required for fruit and vegetable planting, additional insulation measures are required in the planting insulation shed 1. At this time, turn on the external motor of the heater 21 in the device. After the motor is turned on, the heater 21 will deliver warm air to the outside, and the temperature in the planting insulation shed 1 will gradually increase by delivering warm air.

[0055] In the second step, the motor connected to the power arm 31 is turned on, and the connecting handle 312 starts to rotate. When the connecting handle 312 rotates, the long arm 311 fixedly connected to the connecting handle 312 starts to rotate. The power arm 31 is connected to four quadrilateral connecting rods 32 in sequence from left to right. Specifically, the long arm 311 is movably connected to one end of the first side rod 321 through the fourth connecting column 328, the other end of the first side rod 321 is movably connected to one end of the second side rod 323 through the first connecting column 322, the other end of the second side rod 323 is movably connected to one end of the third side rod 324 through the second connecting column 327, the other end of the third side rod 324 is movably connected to one end of the fourth side rod 326 through the third connecting column 325, and the other end of the fourth side rod 326 is movably connected to the first side rod 321 through the fourth connecting column 328. Figure 8 As shown, when the long arm 311 starts to move, it drives the first side rod 321 and the fourth side rod 326 to open and close, and the second side rod 323 and the third side rod 324 reciprocate along with the opening and closing movement of the first side rod 321 and the fourth side rod 326. Fig.16 As shown, when the long arm 311 moves, the entire first movable mechanism 3 will reciprocate on the second movable mechanism 4.

[0056] In the third step, the second connecting column 327 in the quadrilateral connecting rod 32 is connected to the connecting long rod 421 in the rocker arm 42. The entire first movable mechanism 3 has four quadrilateral connecting rods 32, and three connecting long rods 421 are connected to the four quadrilateral connecting rods 32. Fig.17As shown, the connecting long rod 421 passes through the curved groove 463 on the receiving platform 46 and is connected to the first rocking column 422. The first rocking column 422 is connected to one end of the connecting arm 423, and the other end of the connecting arm 423 is connected to the second rocking column 424. The second rocking column 424 is on the square groove 442. The diameter of the second rocking column 424 is adapted to the width of the square groove 442. The second rocking column 424 can slide on the connecting handle B432. When the second connecting column 327 in the second step reciprocates, the connecting long rod 421 connected to the second connecting column 327 also reciprocates. Each connecting long rod 421 is connected to a movable column 23. The outer side of the movable column 23 is sleeved with a grooved sleeve column 22. The top of the grooved sleeve column 22 is connected to the heater 21. The movement of the extension rod 421 drives the movable column 23 to move, the movement of the movable column 23 drives the movement of the grooved sleeve column 22, and the movement of the grooved sleeve column 22 drives the movement of the heater 21 connected to the top of the grooved sleeve column 22. Through the reciprocating motion of the heater 21, when the heater 21 is transporting warm air into the greenhouse, the transported warm air can be evenly supplied from front to back in the entire greenhouse through the linear back and forth motion of the heater 21, avoiding the problem of excessive local temperature caused by the warm air always being fixedly transported to a certain place in the greenhouse. If the fixedly transported warm air is just directed towards fruits and vegetables planted in a certain place, after a long period of blowing, the leaves and other parts of the fruits and vegetables there are at risk of being dried out by high temperature. This phenomenon can be avoided by the linear reciprocating air supply of the heater 21.

[0057] The fourth step is to turn on the motor connected to the connecting pin A414, and the connecting pin A414 starts to rotate in a semicircle, and the connecting pin A414 is fixedly connected to the cylindrical ring A411, and the cylindrical ring A411 is fixedly connected to one end of the connecting handle A412, and then the other end of the connecting handle A412 is fixedly connected to the cylindrical ring B413, and the cylindrical ring B413 is movably connected to the first slot head 441. At the same time, one end of the connecting member 45 is movably connected under the connecting pin A414, and the other end of the connecting member 45 is movably connected to the connecting pin B434, and the connecting pin B434 is fixedly connected to the cylindrical ring D433, and the cylindrical ring D433 is connected to the second On the slot head 443, therefore, when the connecting pin A414 rotates half a circle, it drives the swing slot 44 to swing ninety degrees through cooperation with the connecting piece 45, and the second rocker 424 on the swing slot 44 also swings ninety degrees through the swing of the swing slot 44. The second rocker 424 is connected to the connecting arm 423, and the connecting arm 423 is fixedly connected to the first rocker 422. When the second rocker 424 swings ninety degrees, the connecting arm 423 and the first rocker 422 also swing ninety degrees synchronously. The first rocker 422 is fixedly connected to the connecting long rod 421, and the connecting long rod 421 rotates ninety degrees under the drive of the first rocker 422.

[0058] In the fifth step, after the connecting rod 421 in the fourth step rotates 90 degrees, the movable column 23 fixedly connected to the connecting rod 421 rotates 90 degrees along with the movement of the connecting rod 421. The movable column 23 is provided with a cylindrical protrusion 232, and the outer surface of the cylindrical protrusion 232 is connected with a grooved sleeve column 22. By limiting the moving trajectory of the cylindrical protrusion 232 in the spiral groove 222 on the grooved sleeve column 22, when the cylindrical protrusion 232 rotates 90 degrees, the spiral groove 222 is driven to spirally rotate. The upper surface of the grooved sleeve column 22 is fixedly connected to the heater 21, and the heater 21 is driven by the grooved sleeve column 22 to perform the rising or falling action, that is, the heater 21 can move up and down when delivering warm air to ensure that the upward warm air delivery in the vertical space of the planting insulation shed 1 is uniform, and avoid the concentrated delivery of warm air at a certain height. At the same time, when the heights of fruits and vegetables are different, the upper and lower air supply of the heater 21 can also achieve the goal that fruits and vegetables at different heights can be covered by the warm air.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
