[0006] The effects achieved by the above components are as follows: When using the frost-proof pit, the operator reaches the bottom of the pit through the inlet and outlet pipe, then puts the filler at the bottom of the pit, lights the filler, and then drives the smoke to escape from the pit through the fan at the air duct to increase the temperature at the fruit tree. When the operator does not use the inlet and outlet pipe, the baffle can be moved, so that the support plate drives the column to move, and then the column drives the sliding block to move inside the first slide rail through the support plate.

[0028] Refer to Figures 1-4 As shown in the figure, this embodiment discloses a frost-proof pit for fruit trees in a pit type, which includes a pit body 1 dug underground. An inlet and outlet pipe 4 is provided at the upper end of the pit body 1. Air ducts 5 are provided on both sides of the pit body 1. A fan 6 is provided inside the air ducts 5. A filler material 7 is provided inside the pit body 1. A shielding device 2 is provided at the upper end of the inlet and outlet pipe 4.

[0029] Refer to Figures 1-4 As shown in the figure, this embodiment discloses that the shielding device 2 includes a placing rack 21. The placing rack 21 is fixedly connected to the inlet and outlet pipe 4. A first slide rail 22 is fixedly connected to one side of the placing rack 21. A sliding block 23 is slidably connected inside the first slide rail 22. A clamping block 24 is inserted into one side of the sliding block 23. Two clamping holes 25 are opened on one side of the first slide rail 22. The clamping block 24 is clamped with the clamping hole 25 inside the first slide rail 22. A support plate 26 is fixedly connected to one side of the sliding block 23. A column 27 is fixedly connected to one side of the support plate 26. A baffle plate 28 is fixedly connected to one side of the column 27. The size of the baffle plate 28 is larger than that of the inlet and outlet pipe 4. When using the frost-proof pit, the operator reaches the bottom of the pit body 1 through the inlet and outlet pipe 4, then puts the filler material 7 at the bottom of the pit body 1, then ignites the filler material 7, and then drives the smoke to escape from the pit body 1 through the fan 6 at the air duct 5 to increase the temperature at the fruit tree. When the operator does not use the inlet and outlet pipe 4, the baffle plate 28 can be moved to drive the column 27 to move through the support plate 26, and then the column 27 drives the sliding block 23 to move inside the first slide rail 22 through the support plate 26. When the baffle plate 28 reaches directly above the inlet and outlet pipe 4, the clamping block 24 is moved to make the clamping block 24 pass through the sliding block 23 and reach the clamping hole 25 on one side of the first slide rail 22 to complete the fixation of the position of the sliding block 23, and then the position of the baffle plate 28 is fixed to the upper end of the inlet and outlet pipe 4. By using the shielding device 2, when the inlet and outlet pipe 4 is not in use, the upper end of the inlet and outlet pipe 4 can be shielded to prevent rainwater from reaching the inside of the pit body 1 through the inlet and outlet pipe 4 during rain, which may affect the combustion of the internal filler material 7, thereby improving the use effect of the frost-proof pit for fruit trees in a pit type.

[0030] Refer to Figures 1-4As shown in the figure, in this embodiment, a control frame 29 is provided at the upper end of the baffle 28, and the cross-section of the control frame 29 is U-shaped. When moving the baffle 28, the control frame 29 can be used to increase the contact area between the operator and the baffle 28, making it easier for the operator to move the baffle 28. A rubber sleeve 210 is fixedly connected to one side of the control frame 29, and the size of the rubber sleeve 210 is adapted to the size of the control frame 29. By using the rubber sleeve 210, the friction between the control frame 29 and the operator can be increased, so that the control frame 29 can be more firmly held by the operator. A reinforcing plate 211 is fixedly connected to one side of the column 27, and one side of the reinforcing plate 211 is fixedly connected to the support plate 26. By using the reinforcing plate 211, the connection strength between the support plate 26 and the column 27 can be increased, avoiding the situation of deformation due to force at the connection between the support plate 26 and the column 27. A connecting rope 212 is fixedly connected to one side of the block 24, and one side of the connecting rope 212 is fixedly connected to the sliding block 23. By using the connecting rope 212, the block 24 and the sliding block 23 can be connected to avoid the loss of the block 24. A plurality of diversion grooves 213 are formed on both sides of the baffle 28, and the diversion grooves 213 on a plurality of baffles 28 are arranged at equal intervals. When using the baffle 28, the diversion grooves 213 at the upper end can quickly divert rainwater, thereby improving the use effect of the baffle 28.

[0031] Referring to Figures 1-4 As shown in the figure, in this embodiment, an auxiliary component 3 is provided on one side of the sliding block 23. The auxiliary component 3 includes a second slide rail 31, the second slide rail 31 is fixedly connected to the sliding block 23, and a blocking plate 32 is slidably connected inside the second slide rail 31. When using the block 24, the blocking plate 32 can be moved to make the blocking plate 32 move inside the second slide rail 31, so that the blocking plate 32 reaches the position of the block 24 to limit the position of the block 24. By using the auxiliary component 3, the position of the block 24 can be limited to avoid the situation that the block 24 accidentally disengages from the card hole 25, thereby improving the use effect of the shielding device 2.

[0032] Referring to Figures 1-4 As shown in the figure, in this embodiment, a magnet 33 is fixedly connected to one side of the blocking plate 32, and an iron block 34 is fixedly connected inside the second slide rail 31. The iron block 34 and the magnet 33 are magnetically attracted to each other. By using the magnet 33, the iron block 34 can be adsorbed, making it difficult for the blocking plate 32 to move inside the second slide rail 31, thereby improving the use effect of the blocking plate 32.

[0033] Working principle: When using the frost-proof pit, the operator reaches the bottom of the pit body 1 through the inlet and outlet pipe 4, then puts the filler 7 at the bottom of the pit body 1, lights the filler 7, and then drives the smoke away from the pit body 1 through the fan 6 at the air duct 5 to increase the temperature at the fruit tree. When the operator does not use the inlet and outlet pipe 4, the baffle 28 can be moved through the control frame 29 with a rubber sleeve 210, so that the support plate 26 drives the column 27 to move, and then the column 27 drives the sliding block 23 to move inside the first slide rail 22 through the support plate 26. Then when the baffle 28 reaches directly above the inlet and outlet pipe 4, the moving block 24 is moved so that the block 24 passes through the sliding block 23 and reaches the card hole 25 on one side of the first slide rail 22 to complete the fixation of the position of the sliding block 23, and then the position of the baffle 28 is fixed to the upper end of the inlet and outlet pipe 4. By using the shielding device 2, when the inlet and outlet pipe 4 is not in use, the upper end of the inlet and outlet pipe 4 can be shielded to prevent rainwater from reaching the inside of the pit body 1 through the inlet and outlet pipe 4 when it rains, which may affect the combustion of the internal filler 7, thus improving the use effect of the fruit tree ground pit type frost-proof pit.

[0034] When using the block 24, the blocking plate 32 can be moved to make the blocking plate 32 move inside the second slide rail 31 so that the blocking plate 32 reaches the block 24 to limit the position of the block 24. At this time, the iron block 34 is adsorbed by using the magnet 33, making it difficult for the blocking plate 32 to move inside the second slide rail 31. By using the auxiliary component 3, the position of the block 24 is restricted to prevent the block 24 from accidentally detaching from the card hole 25, thus improving the use effect of the shielding device 2.
